[0003]
[Problems to be Solved by the Invention]
According to the above-mentioned technology, adjustment of height at the position where the stand is set out can only be performed, and unbalance of the bicycle at the time of moving and at the time of stopping is restrained by changing the swing angles of the roller legs 40 for both moving and stopping; therefore, the construction is complicated. In addition, there is no consideration about application to a vehicle whose vehicle height is changed largely before and after folding thereof.
[0004]
Accordingly, it is an object of the present invention to provide a stand structure for foldable vehicle which is simple in construction and can be applied even to a vehicle whose vehicle height is changed


largely before and after folding thereof.
[0005]

The rotary magnet body 112 and the stator 115 are members constituting an electric motor 116. Numeral 117 denotes an axle of the rear wheel 12. [0039]
FIG. 13 is a sectional view (exploded view) showing the wheel structure of the two-wheel vehicle according to the present invention. The wheel 68 includes a hub portion 121 for receiving the axle 117, a disk portion 122 spreading radially outwards from the hub portion 121, and a rim portion 123 provided at the outer circumference of the disk portion 122, with a tire 124 fitted on the rim portion 123.
The disk portion 122 is a portion integrally formed with a drum 127 constituting a drum brake 126 on the side facing the rear swing arm 42. Numeral 128 denotes a cast iron liner which is insert molded on the inside of the drum 127 for enhancing abrasion resistance, 131 denotes a magnet body fitting portion provided at the inside


surface of the rim portion 123 for fitting the rotary magnet body 112, 132 denotes an annular groove for fitting the fixing ring 113, and 133 ... denote positioning pins for positioning the rotary magnet body 112.
[0040]
The rear swing arm 42 includes a convex portion 135 provided at the periphery of the axle 117, and the stator 115 fitted to the convex portion 135 by bolts 137 ..., in which the convex portion 135 functions also as a brake panel (which is a component part of the drum brake 126).
Namely, the convex portion 135 is a portion for fitting thereto brake shoe shafts 138, 138 (the brake shoe shaft 138 on one side is not shown) which constitute a swing shaft for the brake shoe (not shown) to be pressed against the inner circumferential surface of the cast iron liner 128 of the drum 127, and a cam shaft 143 which is formed at its one end with a cam 141 for moving the brake shoe to the drum side and is integrally fitted at its other end with an arm member 142 to be swung attendant on a brake operation.
[0041]
FIG. 14 is a sectional view showing the wheel structure of the two-wheel vehicle according to the present invention, and shows the condition where the axle

117, the stator 115 of the electric motor 116, the brake shoe shafts 138, 138 (symbol 138 on one side is not shown) of the drum brake 126 and the cam shaft 143 are fitted to the convex portion 135 of the rear swing arm 42, the wheel 68 is rotatably fitted to the axle 117 through bearings 145, 146, the drum 127 of the drum brake 126 is integrally formed on the disk portion 122 of the wheel 68, the sensor ring 106 is fitted to the disk portion 122 of the wheel 68 by bolts 147 ..., and the rotary magnet body 112 is fitted to the inner circumferential surface of the rim portion 123. Numeral 148 denotes a collar, 151 and 152 denote oil seals, 153 denotes a washer, 154 denotes a nut, 155 denotes a return spring for the arm member 142, and 156 denotes a tire valve. [0042]
The above-mentioned wheel 68 has a structure in which the electric motor 116 for driving the wheel 68 is incorporated in the wheel 68, and the drum brake 12 6 for braking the wheel 68 is disposed on the radially inner side of the electric motor 116. Therefore, the electric motor 116 and the drum brake 126 can be disposed concentrically, the width of the wheel 68 can be made small, and a small-type compact wheel 68 can be achieved. Such a wheel structure may be adopted for the front

wheel 11 (See FIG. 2).
[0043]
In addition, since the electric motor 116 and the drum brake 126 are provided on the same side of the disk portion 122 of the wheel 68, it is possible to enhance the assemblability of the electric motor 116 and the drum brake 126 to the wheel 68 and the maintainability of the electric motor 116 and the drum brake 126.
[0044]
Further, since the rear swing arm 42 as a rear wheel support member for rotatably supporting the wheel 68 functions also as a brake panel of the drum brake 126 and is fitted with the stator 115 of the electric motor 126, the number of component parts can be reduced as compared with the case where a stator-fitting member is provided and/or the brake panel is specially provided. Besides, at the time of manufacture, component parts (the brake shoe shaft 138, the brake shoe, the cam shaft 143, the arm portion 142, etc.) of the drum brake 126 and the stator 115 can be preliminarily and partly assembled onto the rear swing arm 42, and, separately, the sensor ring 106 and the rotary magnet body 112 can be preliminarily and partly assembled onto the wheel 68; therefore, by the process of fitting the partly assembled wheel 68 to the

partly assembled rear swing arm 42, productivity can be enhanced.
[0045]
Furthermore, with the wheel 68 provided with the rotary magnet body 112, according to the present invention, a slip ring mechanism or the like for supplying electric current to the stator 115 is unnecessitated and structure is simplified, as compared with the case where, for example, the stator is provided on the side of the wheel. In addition, with the rotary magnet body 112 included of the magnetic material ring 111 and the permanent magnets 107 ..., 108 ... fixed on the magnetic material ring 111, the magnetic material ring 111 on which the permanent magnets 107 ..., 108 ... are preliminarily fixed can be fitted to the wheel 68, whereby assemblability can be enhanced as compared with the case where, for example, the permanent magnets are fitted directly to the wheel.

When the folding detection switch for the front and rear wheels is ON (YES), ST09 is entered.
ST09: Passage of electric current to the electric motor and the solenoid is stopped. [0061]
Next, the action of folding the front and rear wheels will be described along the flow shown in the flowchart in FIG. 10.
First, in FIG. 1, the motor operating switch 24 provided on the right-side handle 18 is tilted to the "FOLD" side. [0062]
Then, when the front brake is operated by gripping the front brake lever (not shown) provided on the right-side handle 18, the front lever is locked by the brake lock lever which will be described later, and a rear brake lever (not shown) provided on the left-side handle 17 is ungripped and therefore the rear brake is not operated, it is detected by a front brake operation detection switch (not shown) that the front brake is operated, whereas it is detected by a rear brake operation detection switch (not shown) that the rear brake is not operated, and a control device (not shown)

passes an electric current to the solenoid shown in FIG. 18, thereby operating the actuator 17 8. [0063]
FIGS. 21(a), (b) are action views for illustrating the action of the swing arm unlocking mechanism according to the present invention.
When the actuator 178 (See FIG. 18) is operated, in (a), the arm lock pin 165 is pulled through the wire 168, and is moved as indicated by the arrow, so that the tip end of the arm lock pin 165 is disengaged from the penetration hole 161a of the projected piece 161, and the front swing arm 37 is unlocked.
In (b), when the arm lock pin 165 is disengaged from the penetration hole 161a, the roller of the rollered arm 174c of the lock detection switch 174 comes off from the detection piece 173, so that the lock detection switch 174 is turned OFF. [0064]

In (a) and (b), when the lock detection switch 174 (See FIG. 21(b)) is turned OFF, the control device starts passing an electric current to the electric motor 116,


and the rear wheel 12 is driven at a low speed by the electric motor 116. The rotating direction of the electric motor 116, namely, of the rear wheel 12 at this time is the forward rotation direction (the rotating direction at the time of running, namely, the direction of the arrow).
[0065]
By this, the rear wheel 12 moves to the front side of the vehicle body (the direction of the void arrow (front) is the front side). At this time, the front wheel 11 is in the braked condition and is not moved to the front side of the vehicle body, so that the distance between the front wheel 11 and the rear wheel 12 is decreased, whereby the front swing arm 37 and the rear swing arm 42 respectively unlocked with reference to the vehicle body are tilted with the front swing shaft 57 and the rear swing shaft 58 as centers, respectively, gradually into folded conditions.
[0066]
Then, when the predetermined period of time has elapsed from the start of the passage of electric current to the electric motor 116 or when the front wheel folding detection switch 184 and the rear wheel folding detection switch 186 are both turned ON, the control device stops

the passage of electric current to the electric motor 116. By this, the folding of the front and rear wheels 11, 12 is completed. [0067]
Next, the action of unfolding the front wheel 11 and the rear wheel 12 which have been folded will be described below.
FIG. 23 is a flowchart for illustrating the main points of unfolding the front and rear wheels of the two-wheel vehicle according to the present invention. STXX represents a step number.
ST11: It is judged whether or not an unfolding switch (Here, the motor operating switch is referred to as the unfolding switch in the meaning of using the motor operating switch by tilting to the "UNFOLD" side.) provided on the handle is ON.
When the unfolding switch is OFF (NO), ST11 is carried out again.
When the unfolding switch is ON (YES), ST12 is entered. [0068]
ST12: It is judged whether or not the front brake has been operated by gripping the front brake lever.
When the front brake has not been operated (NO),


ST12 is carried out again.
When the front brake has been operated (YES), ST13 is entered. [0069]
ST13: It is judged whether or not the rear brake lever has been ungripped and the rear brake has not been operated.
When the rear brake has been operated (NO), ST12 is carried out again.
When the rear brake has not been operated (YES), ST14 is entered. [0070]
ST14: It is judged whether or not the lock detection switches on the front swing arm side and on the rear swing arm side are OFF.
When the lock detection switches are ON (NO), ST14 is carried out again.
When the lock detection switches are OFF (YES), ST15 is entered. [0071]
ST15: An electric current is passed to the electric motor to rotate the rear wheel reversely, thereby starting to unfold the front and rear wheels.
ST16: It is judged whether or not the lapse of


time t from the start of passage of electric current to the electric motor is shorter than a predetermined period of time tst.
When t = tst (NO), ST16 is carried out again.
When t ST17: The passage of electric current to the electric motor is stopped. [0072]
The condition of ST14 mentioned above will be described referring to the following figure.

[0073]
In (b), with the arm lock pin 165 moved to the most left-side position, the roller of the lock detection


switch 174 comes off from the detection piece 173, so that the lock detection switch 174 is turned OFF.
Based on this OFF condition, the control device starts passing an electric current to the electric motor 116, in FIGS. 22(a) and (b), so that the front and rear wheels 11, 12 are unfolded. [0074]
Next, the condition immediately before completion of the unfolding of the front and rear wheels 11, 12 will be described.

The handle post 23 is a member provided with step portions 23d, 23e (symbol 23e is not shown; detailed later), adjacently to the groove portions 23b, 23c. [0100]
The action of the handle support mechanism 227 described above will be described below.
FIGS. 37 (a) to (c) are action views for illustrating the action of the knob of the handle support mechanism according to the present invention, in which (a) is a sectional view, and (b) and (c) are views of the bar 266 and the handle post 23 from direction A of (a).
In (a), the knob 236 is pushed, whereby the bar 266

is lifted from the groove portions 23b, 23c of the handle post 23.
[0101]
In (b), with the bar 266 lifted from the groove portions 23b, 23c, the knob 236 comes to be rotatable. Then, the knob 236 is rotated in the direction of the arrow. Since the above-mentioned step portions 23d, 23e are present in the direction of the arrow of each of the groove portions 23b, 23c, the knob 236 can be rotated without interference with the handle post 23.
[0102]
In (c), the knob 236 is shown as being rotated by 90° from the position of (b). The bar 266 comes into the condition of being disposed along the cutout portion 23a of the handle post 23, whereby the knob 236 becomes capable of coming out of the cutout portion 23a of the handle post 23 together with the handle clamp lever 237 (See (a)), namely, the connection between the handle post 23 and the handle clamp lever 237 is released by the knob 236.
[0103]
FIGS. 38(a), (b) are action views for illustrating the actions of the handle clamp lever and peripheral component parts of the handle support mechanism according


to the present invention. While description will be made below based on the constitution on the side of the handle 17, the same action applies also to the side of the handle 18:
In FIGS. 37(a) to (c), the knob 236 is rotated to release the connection between the handle post 23 and the handle clamp lever 237, and, thereafter, in FIG. 38(a), the handle clamp lever 237 is kicked up in the direction of the arrow with the connection pin 243 as a center. [0104]
Returning to FIG. 34, the distance LI between the first end portion 241a of the handle clamp lever 237 and the axis of the connection pin 243 is greater than the distance L2 between the second end portion 241b and the axis of the connection pin 243, and, therefore, in FIG. 38(a), a gap with a distance C is generated between the second end portion 241b and the washer 262 by the kick-up of the handle clamp lever 237. [0105]
With the gap with the distance C thus generated, in (b), the handle 17 can be moved in the direction of the arrow together with the nut member 244 and the center bolt 253, and the convex portion 17d of the handle 17 can be disengaged from the recessed portion 263 of the handle

post 23, whereby restriction on the rotation of the handle 17 is eliminated, and the handle 17 can be folded.
[0106]
FIG. 39 is a front view showing the folded condition of the handles according to the present invention, and shows the condition where the handles 17, 18 are folded to the greatest extent.
Thus, by folding the handles 17, 18, the maximum width WH (The maximum width WH is smaller than the width of the above-mentioned number plate.) of the handles 17, 18 can be made to be very small, as compared with the maximum width of the handles 17, 18 before folding, which is markedly advantageous as to the containing space, particularly, the containing width in the case of mounting the two-wheel vehicle on a vehicle.
[0107]
FIG. 40 is an illustration for illustrating the folding of the rearview mirrors according to the present invention. After the folding of the handles 17, 18 is completed, the rearview mirrors 21, 22 are rotated in the directions of the arrows so as to have roughly the same width as the width in the vehicle width direction of the handles 17, 18 (namely, the interval of the handles 17, 18) . Here, after the rearview mirrors 21, 22 are rotated,

the reflective surfaces of the rearview mirrors 21, 22 are directed to the lateral sides of the vehicle body. Where the maximum width of the rearview mirrors 21, 22 at this time is WM, the maximum width WM is smaller than the width of the above-mentioned number plate. [0108]
