Summary of the Invention

{Technical problem}

In the foregoing electromobile, the stand of the front-wheel-side vehicle body needs to be moved from a horizontal position to a vertical position after the front-wheel-side vehicle body has been removed from the rear-wheel-side vehicle body. This change in the attitude of the stand means additional effort in disassembly.

In the latter scooter, since no stand is provided to support the rear end side of the front-wheel-side vehicle body remote from the rear-wheel-side vehicle body, a person performing the disassembly must support at least the rear end side of the front-wheel-side vehicle body after the front-wheel-side vehicle body is supported by the vehicle body Rear wheel-side vehicle body has been removed.

When removing the front-wheel-side vehicle body, the rear-wheel-side vehicle body is tilted rearward due to its own weight until the projection member of the rear-wheel-side vehicle body comes in contact with the ground as described in the present literature. In some cases, however, the rearward inclination of the rear wheel side vehicle body is controlled by gripping a part of the rear wheel side vehicle body to avoid contact of the rear wheel side vehicle body with a surrounding person or an object. In this case, it is necessary to support the rear wheel side vehicle body when lifting the rear end side of the front wheel side vehicle body, so that it may be impossible to easily perform disassembly of the front wheel side vehicle body and the rear wheel side vehicle body by a person.

The present invention is intended to bring about an improvement of the above-described circumstances and to provide an electric vehicle which enables a front-wheel-side vehicle body and a rear-wheel-side vehicle body to be easily disassembled and assembled by a person, and a method of disassembling it.

{The solution of the problem}

In order to achieve an improvement of the above-described circumstances, the present invention uses the following solutions.

An electric vehicle according to a first aspect of the present invention includes: a front-wheel-side vehicle body; and a rear-wheel-side vehicle body detachably connected to the front-wheel-side vehicle body, the rear-wheel-side vehicle body standing alone when the rear-wheel-side vehicle body is detached from the front-wheel-side vehicle body and tilted toward a vehicle rear side, the rear-wheel-side vehicle body is provided with a first engagement portion adapted for coupling is used with the front wheel side vehicle body, and the first Engaging member is able to support a second engagement part, which is provided on a rear end side of the front-wheel-side vehicle body and is used for the clutch when the rear-wheel-side vehicle body is alone.

In this aspect, for example, when the rear-wheel-side vehicle body is separated from the front-wheel-side vehicle body and stands alone, the second engagement part provided on the rear end side of the front-wheel-side vehicle body is supported by the first engagement part of the rear-wheel-side vehicle body, and the front-wheel-side vehicle body is passed through Front wheels and the first engagement part of the rear wheel-side vehicle body worn. Thus, a person performing disassembly in this state need not support the front-wheel-side vehicle body. When assembling work for assembling the rear wheel side vehicle body with the front wheel side vehicle body is performed, the front wheel side vehicle body is supported by the front wheels, and the first engaging part of the rear wheel side vehicle body stands alone.

While the rear wheel side vehicle body stands alone, the front wheel side vehicle body is supported by the front wheels and the first engagement part of the rear wheel side vehicle body. As a result, dismantling can be easily done.

In the above-described aspect, the first engagement part continuously supports the second engagement part from the lower side until the rear-wheel-side vehicle body is inclined toward the vehicle rear side and stands alone after releasing the connection of the front-wheel-side vehicle body with the rear-wheel-side vehicle body.

In this configuration, a person performing disassembly decouples the front-wheel-side vehicle body and the rear-wheel-side vehicle body from each other and then carries only the rear-wheel-side vehicle body so that the rear-wheel-side vehicle body stands alone. Accordingly, the rear end side of the front wheel side vehicle body is supported by the rear wheel side vehicle body standing alone. This is advantageous to facilitate disassembly.

In this configuration, for example, a person performing disassembly decouples the front-wheel-side vehicle body and the rear-wheel-side vehicle body from each other, and then carries only the rear-wheel-side Vehicle body, so that the rear wheel-side vehicle body is alone. Accordingly, the rear end side of the front wheel side vehicle body is supported by the rear wheel side vehicle body standing alone. This is advantageous to facilitate disassembly.

In the above-described aspect, it is preferable that the rear-wheel-side vehicle body includes an actuator to be operated to release the clutch between the front-wheel-side vehicle body and the rear-wheel-side vehicle body, wherein the rear-wheel-side vehicle body and the front-wheel-side vehicle body are coupled to be ready for driving , and the method further comprises releasing the clutch by operating the operating member while applying force to the vehicle rear side to the rear wheel side vehicle body.

With this configuration, it is only necessary to release the clutch by operating the operating member while applying a force to the rear wheel side vehicle body to tilt in a direction in which the rear wheel side vehicle body stands alone, so that the rear end side of the front wheel side vehicle body by the alone standing rear wheel-side vehicle body is worn. This makes it possible to perform a dismantling easier.

{Advantageous Effects of Invention}

According to the present invention, disassembly and mounting of a front wheel side vehicle body and a rear wheel side vehicle body can be easily performed by a person.

The second cross member 113b touches the tilting surface 127b from the bottom when the rear wheel side vehicle body 120 around the rotation axis line 20a the rear wheels 20a is inclined to the vehicle front, while the first cross member 113a of the front wheel side frame 111 in the pair of first recesses 121 is placed (see 10 ).

If the second cross member 113b from below with the tilting surface 127b comes into contact, the clutch securing element 127 against the pressure force of the pressure element 127d tilted to the vehicle front, and accordingly, the second cross member 113b in the second recesses 121b used. As soon as the second cross member 113b in the second recesses 121b is inserted, the clutch securing element 127 through the pressure element 127d tilted to the vehicle rear, and the clutch of the front wheel-side vehicle body 110 with the rear wheel side vehicle body 120 is through the clutch securing element 127 maintained.

Each tilting element 126a is with an element engaging part 126e provided that from the top, the vehicle rear or the bottom in the cross member 124a intervenes. The tilting element 126a is also on the other end side of the element-engaging part 126e with a locking element engaging part 126f provided from the top or the vehicle rear side in an engagement pin 128a engages on an end part of a tilt protection element (first restriction means) 128 is provided.

A middle part of each anti-tip element 128 gets from the rear wheel side frame 121 worn, is about a running in the vehicle width direction Kippachslinie 128b swiveling and at one end (lower end) with the engagement pin 128a Mistake. If an end part of the anti-tip element 128 is inclined to the front of the vehicle, the engagement between the engagement pin 128a and the lock member engaging part 126f from every tipping prevention element 126 released so that the other end part of the tipping prevention element 126 can be tilted upwards.

If any tipping prevention element 126 is inclined upward, engages the lock bolt engaging part 126f the overturn prevention element 126 in the cross member (second limiting means) 124a from the top or the vehicle rear side, and accordingly, the upward inclination of the overturn preventing member becomes 126 limited.

In other words, when the locking element engaging part 126f each tipping prevention element 126 with the engagement pin 128a of the anti-tip element 128 is the upward inclination of the overturning prevention element 126 Limited beyond a first tilted position. When the locking element engaging part 126f each tipping prevention element 126 with the crossbeam 124a is engaged, is the upward inclination of the overturning prevention element 126 Limited beyond a second tilted position. If the element engaging part 126e each tipping prevention element 126 with the crossbeam 124a is engaged, is the downward inclination of the overturning prevention element 126 Limited beyond a third tilted position. The downward slope of each tipping prevention element 126 beyond the third inclination position may be restricted when part of the overturn preventing member 126 in another part of the rear wheel side vehicle body 120 intervenes. The second tilt position is higher than the first tilt position, and the third tilt position is at a height that is equal to or slightly lower than the first tilt position.

The other end part of the anti-tip element 128 is with an end part of a connecting element 129 connected to plate form, while the other end part of the connecting element 129 with the clutch securing element 127 at one of the Kippachslinie 127c coupled separate position. Through the coupling through the connecting element 129 grips the engagement pin 128a in the locking member engaging part 126f or at a position where the engagement pin is located 128a in the locking element engaging part 126f can engage when the clutch locking element 127 in the locking position A located. The engagement pin 128a however, it does not interfere with the locking element engaging part 126f when the clutch securing element 127 in the retracted position B located.

The other end side of the anti-tip element 128 is with one end of an operating lever 130 connected as actuating means. The operating lever 130 is about the rotation axis line 128b of the anti-tip element 128 tilted. Such as in the 1 and 6 shown, the other end of the operating lever protrudes 130 from the rear wheel side cover 120a the rear wheel side vehicle body 120 out. With this configuration, the connection between the engagement pin 128a and the lock member engaging part 126f be solved and the clutch securing element 127 can in the retracted position B by tilting the operating lever 130 be positioned to the vehicle rear or down.

Hereinafter, an exemplary method for releasing the connection of the front-wheel-side vehicle body 110 with the rear wheel side vehicle body 120 described in the thus configured electric vehicle.

First, when the seat unit 40 from the rear wheel side vehicle body 120 is removed, the operating lever 130 in the direction of the vehicle rear or inclined downwards, while the handle part 125c with one hand from the upper end side of the back surface 33b of the seat carrier part 33b protrudes, and on the handle part 125c a force is applied upwards or in the direction of the vehicle rear side. By this operation, the connection between the engagement pin 128a and the lock member engaging part 126f solved, the clutch securing element 127 is in the retracted position B , and the second cross member 113b dissolves from the second recesses 121b ,

In this state, when the rear wheel-side vehicle body 120 around the wheel shaft of the rear wheels 20 tilted back, come the auxiliary wheels 126b at the other end part of the overturn prevention elements 126 in contact with the ground. When the rear wheel-side vehicle body 120 around the wheel shafts of the rear wheels 20 is further inclined backwards, engages the locking element-engaging part 126f each tipping prevention element 126 in the cross member 124a in the second inclination position, so that the upward inclination of the overturn preventing element 126 is limited.

In this state, the position of the center of gravity of the rear wheel-side vehicle body is located 120 preferably at or near a position between the ground-level positions of the rear wheels 20 and the on-ground positions of the auxiliary wheels 126b the overturn prevention element 126 in vehicle front-back direction. Accordingly, the rear wheel side vehicle body becomes 120 from the rear wheels 20 and the overturn prevention elements 126 sturdy worn.

When the rear wheel-side vehicle body 120 tilted backwards, is every first recess 121 , as in 7 shown, open obliquely upwards and stably carries the first cross member 113a of the front-wheel-side vehicle body 110 , In other words, as in 7 shown, it is unlikely that the first cross member 113a of the front-wheel-side vehicle body 110 due to the front contact part FC from the first recesses 121 falls. Thus, the front wheel-side vehicle body 110 from the rear wheel side vehicle body 120 be removed by the hand from the handle part 125c dissolved and the rear end side of the front wheel-side vehicle body 110 is raised to the first cross member 113a from the first recesses 121 to remove. Also in this case, the rear wheel side vehicle body 120 from the rear wheels 20 and the overturn prevention elements 126 sturdy worn. After this dismantling, the front wheel-side vehicle body becomes 110 and the rear wheel side vehicle body 120 loaded in an automobile or the like.

Hereinafter, an exemplary method for coupling the front wheel side vehicle body 110 and the rear wheel side vehicle body 120 described.

First come the auxiliary wheels 126b the overturn prevention elements 126 and the rear wheels 20 in contact with the ground while the tipping prevention elements 126 in the second tilt position. In this state, the first cross member 113a of the front-wheel-side vehicle body 110 in the first recesses 121 used. Accordingly, the front wheel side vehicle body becomes 110 through the first recesses 121 and the front wheels 10 carried.

Subsequently, the rear wheel side vehicle body 120 around the wheel shafts of the rear wheels 20 tilted forward. Accordingly, the second cross member touches 113b the tilting surface 127b the clutch securing element 127 from the bottom, as in 10 shown. In this state, when the rear wheel-side vehicle body 120 around the wheel shafts of the rear wheels 20 is further tilted forward, the clutch securing element 127 inclined to the vehicle front, and accordingly, the second cross member 113b in the second recesses 121b used. If the second cross member 113b in the second recesses 121b is used, the clutch securing element 127 through the pressure element 127d tilted to the vehicle rear side, and the clutch of the front-wheel-side vehicle body 110 with the rear wheel side vehicle body 120 is through the clutch securing element 127 maintained.

As described above, according to the present embodiment, when the rear wheel side vehicle body 120 from the front wheel side vehicle body 110 is removed and the rear wheel-side vehicle body 120 alone stands, the first cross member 113a (second engagement part), which is on the rear end side of the front wheel-side vehicle body 110 is provided by each first recess 121 (First engagement part) of the rear wheel side vehicle body 120 worn, and the front-wheel-side vehicle body 110 gets through the front wheels 10 and the first recesses 121 the rear wheel side vehicle body 120 carried. Thus, a person performing dismantling in this state must use the front-wheel-side vehicle body 110 do not wear. When assembling work for assembling the rear wheel side vehicle body 120 to the front wheel side vehicle body 110 is performed, the front wheel-side vehicle body 110 through the first recess 121 the stand-alone rear wheel-side vehicle body 120 and the front wheels 10 be supported.

Every first recess 121 the rear wheel side vehicle body 120 standing alone contains the lower contact part LC , which is the first cross member 113a of the front-wheel-side vehicle body 110 contacted from the bottom, and the front contact part FC at the vehicle front with respect to the lower contact part LC - arranged and higher than the lower contact part LC is positioned. In this configuration, the movement of the first cross member 113a in the direction of the vehicle front through the front contact part FC of the first engaging part 121 restricted or prevented while the first cross member 113a of front wheel-side vehicle body 110 in the first recesses 121 the stand-alone rear wheel-side vehicle body 120 intervenes.

The rear wheel-side vehicle body 120 is tilted backwards and is in operation, while the front-wheel-side vehicle body 110 and the rear wheel side vehicle body 120 coupled together, the actuating lever 130 with one hand alone, so that the clutch is released while the handle part 125c held with the other hand, and then the handle part 125c is raised. While the rear wheel-side vehicle body 120 stands alone, becomes the front wheel-side vehicle body 110 from the front wheels 10 and the first recesses 121 the rear wheel side vehicle body 120 carried. As a result, dismantling can be easily done.

Every first recess 121 continues to carry the first cross member 113a from the bottom between a state in which the clutch of the front wheel-side vehicle body 110 with the rear wheel side vehicle body 120 is dissolved, and a state in which the rear wheel-side vehicle body 120 is tilted to the vehicle rear and stands alone. Thus, a person performing disassembly releases the clutch of the front wheel-side vehicle body 110 with the rear wheel side vehicle body 120 and then carries only the rear wheel-side vehicle body 120 such that the rear wheel side vehicle body 120 alone stands. In this process, the rear end side of the front wheel side vehicle body becomes 110 from the stand-alone rear wheel-side vehicle body 120 carried. This structure is advantageous to facilitate disassembly.

In the present embodiment, when the tilt limit by the anti-tip element 128 through the operating lever 130 is solved, the tipping prevention elements 126 tilted to the second inclination position, which is higher than the first inclination position, so that the upward inclination by the cross member 124a is limited in the position.

So if the auxiliary wheels 126b the overturn prevention elements 126 come in contact with the ground, the position of the center of gravity of the rear wheel-side vehicle body 120 shifted to the vehicle rear side and for example between an on-earth located part of each rear wheel 20 and an on-earth portion of each auxiliary wheel 126b arranged. Accordingly, the rear wheel side vehicle body becomes 120 from the rear wheels 20 and the overturn prevention elements 126 sturdy worn.

In the present embodiment, when the clutch securing element 127 through the operating lever 130 is moved to the retracted position B to the locking of the coupling of the front wheel-side vehicle body 110 with the rear wheel side vehicle body 120 to solve the tilt limit by the anti-tip element 128 canceled. Accordingly, the overturn preventing elements become 126 inclined to the second tilting position, which is higher than the first tilting position, so that the upward inclination by the cross member 124a is limited in the position. Thus, the rear wheel side vehicle body becomes 120 in a clutch release operation of the rear wheels 20 and the overturn prevention elements 126 sturdy worn. This is advantageous to facilitate the clutch release operation.

When the anti-tip element 128 is tilted, the clutch securing element 127 through the connecting element 129 tilted. Thus, at a clutch release at the same time the inclination limitation by the anti-tip element 128 solved and thus easily and reliably reaches a state in which the rear wheel-side vehicle body 120 from the rear wheels 20 and the overturn prevention elements 126 is worn stable. The operating lever 130 can on the clutch securing element 127 be attached. In this case, the anti-tip element becomes 128 through the connecting element 129 tilted when the clutch securing element 127 is tilted.

The overturn prevention elements 126 that are in the first tilted position to prevent the rear of the scooter tipping over when the front wheel-side vehicle body 110 and the rear wheel side vehicle body 120 connected to each other, serve to support the rear wheel-side vehicle body 120 when the connection between the rear wheel side vehicle body 120 and the front-wheel-side vehicle body 110 is solved. Therefore, it is not necessary to have a special member for supporting the rear wheel side vehicle body 120 provided.

It is possible to change the state of inclination limitation through the anti-tilt element 128 and the lock state by the clutch lock member 127 physically check by the tilt state of the operating lever 130 checked on the rear wheel side vehicle body 120 is provided and tiltable. This becomes an unreasonable operation such as the rearward tilting of the rear wheel side vehicle body 120 prevented while the tilt limit by the anti-tip element 128 or the lock by the clutch securing element 127 not released. In addition, it is possible to control the state of tilt limitation by the anti-tip element 128 and the lock state by the clutch lock member 127 physically check when the front wheel-side vehicle body 110 and the rear wheel side vehicle body 120 to be coupled with each other.

The downward slope of the overturn prevention elements 126 is through the cross member 124a the rear wheel side frame 121 limited, while the upward inclination by the anti-tip element 128 is limited. In addition, the upward inclination of the overturn prevention elements becomes 126 through the same cross member 124a limited if the tilt limit by the anti-tip element 128 is released and the tipping prevention elements 126 inclined to the second inclination position. This makes it possible to simplify a structure for controlling the tilt of the overturn prevention elements 126 , which is advantageous for the electric vehicle, for which a weight reduction is strongly required and in which a limited space is available.

In the present embodiment, the anti-tilt element 128 and the clutch securing element 127 through the operating lever 130 tilted. For example, at least one of the anti-tilt element 128 and the clutch securing element 127 be coupled to the working shaft of a transmission, and the drive shaft of the transmission can be driven by a motor. In this case, the controller can 80 the motors 50 based on a lock enable signal or one from the controller 80 control received blocking signal.

In the present embodiment, the front wheel side vehicle body becomes 110 and the rear wheel side vehicle body 120 dismantled after the seat unit 40 from the mobility body 30 was removed. However, it is possible to use the front wheel-side vehicle body 110 and the rear wheel side vehicle body 120 to disassemble without the seat unit 40 expand. The seat unit 40 does not have to be removed when the seat unit 40 on the front wheel side vehicle body 110 not on the rear wheel side vehicle body 120 is attached, or if the seat unit 40 is small.

In the present embodiment, the overturn preventing members protrude 126 in terms of the rear wheels 20 towards the vehicle rear side, and when the tipping prevention elements 126 tilted upward, the rear wheel side vehicle body 120 from the auxiliary wheels 126b at the other end portions of the overturn prevention elements 126 and the rear wheels 20 carried. The overturn prevention elements 126 However, do not allow auxiliary wheels 126b include. Also in this case, the reverse tilting of the scooter by the tipping prevention elements 126 be prevented, and the rear wheel-side vehicle body 120 can through the other end portions of the tipping prevention elements 126 and the rear wheels 20 be worn.

In the present embodiment, for example, when the position of the center of gravity of the rear wheel-side vehicle body 120 at the vehicle rear side with respect to the rotation axis line 20a the rear wheels 20a The tipping prevention elements may be located 126 configured to not tilt up beyond the first tilting position, and in addition, a protruding member may be provided with respect to the rear wheel side vehicle body 120 protrudes toward the vehicle front.

In this case, the protrusion member may be inclined in an up-down direction with one end of the rear-wheel-side vehicle body 120 will be carried. For example, the protrusion member is in the first inclined position and extends in the vehicle front-rear direction while the front-wheel-side vehicle body 110 and the rear wheel side vehicle body 120 coupled together. Then, when or after releasing the clutch of the front-wheel-side vehicle body 110 with the rear wheel side vehicle body 120 , The projection element can be tilted in the second tilted position, which is higher than the first tilted position. Accordingly, the rear wheel side vehicle body becomes 120 through the other end part of the projection element and the rear wheels 20 supported, and the position of the center of gravity of the rear wheel-side vehicle body 120 is shifted from that of the clutch state to the vehicle front.

The rear wheel side frame 121 may be provided with a cross member, an engagement pin or the like, which instead of the first recesses 121 extend in the vehicle width direction, and the side members 112 of the front wheel side frame 111 For example, they may be provided with recesses which each having a substantially U-shape and obliquely down to the vehicle front side instead of the first cross member 113a are open. In this configuration, the cross member, the engagement pin or the like of the rear wheel side frame engages 121 into the recesses.

In addition, instead of the second recesses 121b of the rear wheel side frame 121b a cross member, an engagement pin or the like may be provided, and the side members 112 of the front wheel side frame 111 For example, can be provided with recesses, each having a substantially U-shape, instead of the second cross member 113b is open to the top. In this configuration, the cross member, the engagement pin or the like of the rear wheel side frame engages 121 into the recesses.
