Disclosure of Invention
Problems to be solved by the invention
In the two electric vehicles, if the center of gravity of the rear wheel-side vehicle body is not disposed rearward of the rotation axis of the rear wheel, the rear wheel-side vehicle body cannot be stably supported by the projecting member and the rear wheel, and thus the degree of freedom in designing the rear wheel-side vehicle body is low.
The present invention has been made in view of the above circumstances, and an object thereof is to provide an electric vehicle and a disassembling method thereof, in which a rear wheel-side vehicle body is detached from a front wheel-side vehicle body, the rear wheel-side vehicle body can be stably supported by a protruding member protruding from a rear wheel and the rear wheel, and the degree of freedom in designing the rear wheel-side vehicle body can be improved.
Means for solving the problems
In order to solve the above problems, the present invention adopts the following means.
The invention according to claim 1 provides an electric vehicle, including: a front wheel side vehicle body; a rear wheel side vehicle body detachably coupled to the front wheel side vehicle body; a projecting member which is tiltable in a vertical direction, one end side of which is supported by the rear wheel-side vehicle body and the other end of which projects forward or rearward of the vehicle with respect to an outer peripheral surface of a rear wheel provided on the rear wheel-side vehicle body; a 1 st regulating member that regulates tilting of the protruding member so that the protruding member does not tilt above a 1 st tilting position; a 2 nd regulating means for regulating the tilt of the projecting member so that the projecting member does not tilt above a 2 nd tilt position located above the 1 st tilt position; and an operation member capable of releasing the tilt restriction by the 1 st restriction member.
In this configuration, when the tilt restriction by the 1 st restricting member is released by the operating member, the projecting member tilts to the 2 nd tilting position above the 1 st tilting position, and the 2 nd restricting member restricts upward tilting at that position.
For example, in a state where the rear wheel-side vehicle body is connected to the front wheel-side vehicle body in a state where the tilt is restricted by the first restricting member 1, the other end portion of the projecting member is positioned in the vicinity of the ground surface behind the rear wheel in the vehicle, and the center of gravity of the rear wheel-side vehicle body is positioned in the front of the rotation axis of the rear wheel in the vehicle, the center of gravity position is not disposed between the ground contact portion of the rear wheel and the other end portion of the projecting member, and therefore, even if the other end portion of the projecting member is grounded, the rear wheel-side vehicle body cannot be stably supported by the rear wheel and the projecting member.
In contrast, in this aspect, when the projecting member is tilted to the 2 nd tilting position above the 1 st tilting position by the operating member and the other end portion of the projecting member is grounded, the center of gravity position of the rear wheel side vehicle body is moved rearward of the vehicle, and for example, the center of gravity position is disposed between the grounded portion of the rear wheel and the other end portion of the projecting member, so that the rear wheel side vehicle body can be supported by the rear wheel and the projecting member. The same applies to the case where the other end portion of the protruding member is located in the vicinity of the ground in front of the vehicle with respect to the rear wheel and the center of gravity of the rear wheel-side vehicle body is located in the vicinity of the ground in front of the vehicle with respect to the rear wheel, in a state where the rear wheel-side vehicle body is coupled to the front wheel-side vehicle body.
In the above aspect, it is preferable that the electric vehicle further includes a coupling lock member provided in the rear wheel-side vehicle body and movable to a lock position at which the coupling between the front wheel-side vehicle body and the rear wheel-side vehicle body is maintained and a retreat position at which the coupling can be released, the electric vehicle is configured such that the coupling lock member is moved from the lock position to the retreat position when the operation member is operated, and the electric vehicle is configured such that the tilt restriction by the 1 st restriction member is released when the coupling lock member is moved from the lock position to the retreat position by the operation of the operation member.
In this case, when the coupling lock member is moved to the retracted position by the operating member and the lock of the coupling between the front wheel-side vehicle body and the rear wheel-side vehicle body is released, the tilt restriction by the 1 st restricting member is released, and the projecting member tilts to the 2 nd tilt position above the 1 st tilt position and is restricted from tilting upward by the 2 nd restricting member at that position. Therefore, when the releasing operation of the coupling is performed, the rear wheel side vehicle body can be stably supported by the rear wheel and the projecting member, and therefore, the releasing operation of the coupling is advantageously performed easily.
In the above-described aspect, it is preferable that the 1 st regulating member is a tilt lock member that engages with the projecting member at the 1 st tilt position to regulate the tilt, and the electric vehicle further includes a link mechanism that links a movement of the coupling lock member from the lock position to the retreat position and a movement of the tilt lock member from a position where the tilt lock member engages with the projecting member to a position where the engagement with the projecting member is released.
In this case, when one of the coupling lock member and the tilt lock member is tilted, the other of the coupling lock member and the tilt lock member is also tilted by the link mechanism, and therefore, when the releasing operation of the coupling is performed, the tilt restriction by the 1 st restriction member is released in an interlocking manner, and the rear wheel-side vehicle body can be stably supported by the rear wheel and the projecting member easily and reliably.
In the above aspect, it is preferable that the projecting member is a member that prevents the electric vehicle from falling over backward when the projecting member is disposed at the 1 st tilt position.
In this case, since the rear wheel-side vehicle body, the connection of which to the front wheel-side vehicle body has been released, can be stably supported using the projecting member that prevents the electric vehicle from tipping over rearward, it is not necessary to provide a dedicated member for supporting the rear wheel-side vehicle body.
In the above aspect, it is preferable that the operating member is a tiltable operating lever provided to the rear wheel side vehicle body, and the electric vehicle is configured such that one of the coupling lock member and the tilt lock member is operated and the other of the coupling lock member and the tilt lock member is operated via the link mechanism by tilting of the operating lever.
In this case, since the tilt restriction state by the 1 st restriction member and the lock state by the coupling lock member can be physically confirmed by confirming the tilt state of the operation lever, it is possible to prevent an unreasonable operation such as tilting the rear wheel side vehicle body in a state where the tilt restriction by the 1 st restriction member and the lock by the coupling lock member are not released. In addition, even when the front wheel side vehicle body and the rear wheel side vehicle body are connected, the tilt restriction state by the 1 st restriction member and the lock state by the connection lock member can be physically confirmed.
In the above-described aspect, preferably, the projecting member is brought into contact with a predetermined frame constituting the rear wheel-side vehicle body, so that the projecting member is restricted from tilting to a position below the 1 st tilting position or tilting to a position below the 3 rd tilting position below the 1 st tilting position, and the projecting member is brought into contact with the predetermined frame, so that the projecting member is restricted from tilting to a position above the 2 nd tilting position.
In this case, in a state where the upward tilting is restricted by the 1 st restricting member, when the downward tilting of the projecting member is restricted by the predetermined frame and the projecting member is tilted to the 2 nd tilting position based on the release of the tilting restriction by the 1 st restricting member, the upward tilting of the projecting member is also restricted by the same frame. Therefore, the structure for controlling the tilting of the protruding member can be made simple, which is advantageous in an electric vehicle that has a strong demand for weight reduction and a limited design space.
A second aspect of the present invention provides a method of disassembling an electric vehicle capable of disassembling a rear wheel-side vehicle body from a front wheel-side vehicle body, wherein the rear wheel-side vehicle body includes a projecting member that is tiltable in an up-down direction and one end side of which is supported by the rear wheel-side vehicle body, and a 1 st regulating member that projects toward a vehicle front side or a vehicle rear side from an outer peripheral surface of a rear wheel provided in the rear wheel-side vehicle body, and the 1 st regulating member regulates tilting of the projecting member so as not to tilt the projecting member to a position above a 1 st tilting position, the method comprising: releasing the tilt restriction by the 1 st restriction member to tilt the protruding member to a 2 nd tilt position above the 1 st tilt position; and grounding the other end portion of the projecting member disposed at the 2 nd tilting position, and supporting the rear wheel side vehicle body by the other end portion and the rear wheel.
For example, in a state where the rear wheel-side vehicle body is connected to the front wheel-side vehicle body in a state where the tilt is restricted by the first restricting member 1, the other end portion of the projecting member is positioned in the vicinity of the ground surface behind the rear wheel in the vehicle, and the center of gravity of the rear wheel-side vehicle body is positioned in the front of the rotation axis of the rear wheel in the vehicle, the center of gravity position is not disposed between the ground contact portion of the rear wheel and the other end portion of the projecting member, and therefore, even if the other end portion of the projecting member is grounded, the rear wheel-side vehicle body cannot be stably supported by the rear wheel and the projecting member.
In contrast, in this aspect, when the projecting member is tilted to the 2 nd tilting position above the 1 st tilting position and the other end portion of the projecting member is grounded, the center of gravity position of the rear wheel side vehicle body is moved rearward of the vehicle, and for example, the center of gravity position is disposed between the grounding portion of the rear wheel and the other end portion of the projecting member, so that the rear wheel side vehicle body can be supported by the rear wheel and the projecting member. The same applies to a state in which the rear wheel-side vehicle body is coupled to the front wheel-side vehicle body, and the other end of the protruding member is positioned in the vicinity of the ground in front of the vehicle with respect to the rear wheel, and the center of gravity of the rear wheel-side vehicle body is positioned in the vicinity of the ground in front of the vehicle with respect to the rotation axis of the rear wheel.
ADVANTAGEOUS EFFECTS OF INVENTION
With the present invention, after the rear wheel-side vehicle body is detached from the front wheel-side vehicle body, the rear wheel-side vehicle body can be stably supported by the projecting member projecting from the rear wheel and the rear wheel, and the degree of freedom in designing the rear wheel-side vehicle body can be improved.

The setting of the lock of the electric vehicle includes setting of a password for applying the lock, setting of a timing for releasing the lock, and the like. The setting signal of the setting unit 43c is transmitted to a control unit 60 described later, and the setting of the electric vehicle can be registered or changed in the control unit 60.
As shown in fig. 12, the control unit 60 has a control device 80 and a motor driver 70 for driving each motor 50.
The motor driver 70 is connected to the battery BA via an electric power line and to each motor 50 via an electric power line, and supplies electric power to each motor 50 to drive each motor 50.
The control device 80 includes: a control section 81 having, for example, a CPU, a RAM, and the like; a storage device 82 having a nonvolatile memory, a ROM, and the like; and a transmitting/receiving unit 83. A program for controlling the electric vehicle is stored in the storage device 82, and the control unit 81 operates according to the program, and the control unit 81 transmits a drive signal for driving each motor 50 to the motor driver 70 in accordance with signals from the operation unit 43a and the setting unit 43 c.
Next, a connection structure for connecting the front wheel side vehicle body 110 and the rear wheel side vehicle body 120 will be described.
As shown in fig. 4 to 6, each side member 122a of the rear wheel side frame 121 is formed with a 1 st substantially U-shaped recess (1 st rear engagement portion) 121a that opens toward the vehicle front, and is formed with a 2 nd substantially U-shaped recess (2 nd rear engagement portion) 121b that is disposed further toward the vehicle front than the 1 st recess 121a and opens downward. The 1 st recessed portion 121a is a portion where the 1 st cross member 113a of the front wheel side frame 111 is engaged, and the 2 nd recessed portion 121b is a portion where the 2 nd cross member 113b of the front wheel side frame 111 is engaged (see fig. 9).
More specifically, as shown in fig. 7, the 1 st cross member 113a of the front wheel-side frame 111 is placed in the pair of 1 st concave portions 121a in a state in which the rear wheel-side vehicle body 120 is tilted rearward about the rotation axis 20a of the rear wheel 20, as compared with a state in which the rear wheel-side vehicle body 110 is connected thereto. In this state, since the 1 st recessed portion 121a is opened diagonally upward, the 1 st cross member 113a of the front wheel-side vehicle body 110 is less likely to fall off from the 1 st recessed portion 121 a.
Next, as shown in fig. 8 and 9, when the rear wheel-side vehicle body 120 is tilted toward the vehicle front about the rotation axis 20a of the rear wheel 20, the 2 nd cross member 113b of the front wheel-side frame 111 enters the pair of 2 nd recessed portions 121b from below. Thus, the movement of the 1 st cross member 113a in the vertical direction with respect to the rear wheel side frame 121 is restricted by the pair of side surfaces 121c of the 1 st concave portion 121a shown in fig. 11, and the movement of the 2 nd cross member 113b in the upward direction with respect to the rear wheel side frame 121 is restricted by the bottom surface 121f of the 2 nd concave portion 121b shown in fig. 11. Further, the movement of the 2 nd cross member 113b in the front-rear direction with respect to the rear wheel side frame 121 is restricted by the pair of side surfaces 121e (see fig. 11) of the 2 nd recessed portion 121b or the pair of side surfaces 121e of the 2 nd recessed portion 121b and a coupling lock member 127 described later. In this way, the front wheel side vehicle body 110 and the rear wheel side vehicle body 120 are coupled. Further, the movement of the 1 st cross member 113a rearward with respect to the rear wheel side frame 121 is also restricted by the bottom surface 121d of the 1 st recess 121 a.
As shown in fig. 4 and 6, the rear wheel side frame 121 is provided with a coupling lock member 127 that tilts about a tilting axis 127c extending in the vehicle width direction. One end side of the coupling lock member 127 is supported by the pair of side members 122a, any one of the plurality of cross members 124a to 124c, the support frame 125, and the like, and the coupling lock member 127 tilts about the tilt axis 127 c. In the present embodiment, the coupling lock member 127 is disposed on the vehicle width direction inner side of the pair of 2 nd concave portions 121b provided in the pair of side members 122a in the vehicle width direction.
The coupling lock member 127 is biased by a biasing member 127d such as a torsion spring so that the other end side of the coupling lock member 127 tilts rearward. Further, when the coupling lock member 127 is tilted rearward by the biasing member 127d, a part of the coupling lock member 127 or a member fixed to the coupling lock member 127 abuts a part of the rear wheel side frame 121, and the coupling lock member 127 is configured not to be tilted rearward of the vehicle from the abutting position.
The coupling lock member 127 is formed with a projecting portion 127a projecting rearward, and when the coupling lock member 127 is tilted rearward by the biasing member 127d and is disposed in the lock position a shown by the solid line in fig. 6, the projecting portion 127a comes into contact with the 2 nd cross member 113b entering the 2 nd recessed portion 121b from below as described above. Therefore, the engagement between the 2 nd cross member 113b and the 2 nd concave portion 121b is maintained by the coupling lock member 127. That is, the coupling between the front wheel side vehicle body 110 and the rear wheel side vehicle body 120 is maintained by the coupling locking member 127. When the coupling lock member 127 is disposed at the lock position a, as shown in fig. 11, a part of the protrusion 127a (a part in the vehicle rear direction) is disposed at a position behind the vehicle rear side surface 121e out of the pair of side surfaces 121e of the 2 nd recess 121b.
On the other hand, when the coupling lock member 127 is tilted toward the vehicle front and disposed at the retracted position B shown in fig. 6, the projecting portion 127a is not in contact with the 2 nd cross member 113B, and the coupling between the front-wheel-side vehicle body 110 and the rear-wheel-side vehicle body 120 can be released or the coupling between the front-wheel-side vehicle body 110 and the rear-wheel-side vehicle body 120 can be released.
Further, an inclined surface 127b is provided on the vehicle rear side surface of the other end side of the coupling lock member 127, and the inclined surface 127b is inclined from below to above toward the vehicle rear side in a state where the front-wheel-side vehicle body 110 and the rear-wheel-side vehicle body 120 are coupled. When the rear-wheel-side vehicle body 120 is tilted forward in the vehicle about the rotation axis 20a of the rear wheel 20 in a state where the 1 st cross member 113a of the front-wheel-side frame 111 enters the pair of 1 st recesses 121a, the 2 nd cross member 113b is configured to abut against the tilted surface 127b from below (see fig. 10).
When the 2 nd cross member 113b abuts on the inclined surface 127b from below, the connection locking member 127 tilts toward the vehicle front against the biasing force of the biasing member 127d, and the 2 nd cross member 113b enters the 2 nd recessed portion 121b. When the 2 nd cross member 113b enters the 2 nd recessed portion 121b, the coupling lock member 127 tilts toward the vehicle rear side by the biasing member 127d, and the coupling between the front wheel-side vehicle body 110 and the rear wheel-side vehicle body 120 is maintained by the coupling lock member 127.
Each tilting member 126a is provided with a beam engagement portion 126e that engages with the cross beam 124a from above, the vehicle rear, or below. Further, a lock member engaging portion 126f is provided on the other end side of the beam engaging portion 126e of each tilt member 126a, and the lock member engaging portion 126f engages with an engaging pin 128a provided at one end of the tilt lock member (1 st regulating member) 128 from above or behind the vehicle.
The center side of each tilt lock member 128 is supported by the rear wheel side frame 121 so as to be tiltable about a tilt axis line 128b extending in the vehicle width direction, and an engagement pin 128a is provided at one end (lower end) of each tilt lock member 128. When one end portion of the tilt lock member 128 is tilted toward the vehicle front, the engagement between the engagement pin 128a and the lock member engagement portion 126f of the anti-toppling member 126 is released, and the other end portion of the anti-toppling member 126 is allowed to tilt upward.
When the anti-toppling member 126 is tilted upward, the lock member engagement portion 126f of the anti-toppling member 126 engages with the cross member (2 nd restricting member) 124a from above or behind the vehicle, whereby the upward tilting of the anti-toppling member 126 is restricted.
That is, the tilt of the anti-toppling member 126 is restricted to the position above the 1 st tilt position by engaging the lock member engaging portion 126f of the anti-toppling member 126 with the engaging pin 128a of the tilt lock member 128. When the lock member engagement portion 126f of the anti-toppling member 126 is engaged with the cross member 124a, tilting of the anti-toppling member 126 to a position above the 2 nd tilting position is restricted. Further, the beam engagement portion 126e of the anti-toppling member 126 is engaged with the cross beam 124a, thereby restricting the anti-toppling member 126 from tilting to a position below the 3 rd tilting position. A part of the anti-toppling member 126 may be engaged with another part of the rear wheel-side vehicle body 120, thereby restricting the anti-toppling member 126 from tilting to a position below the 3 rd tilting position. The 2 nd tilt position is a position above the 1 st tilt position, and the 3 rd tilt position is a position equivalent to the 1 st tilt position or a position slightly below the 1 st tilt position.
One end of a plate-shaped link member 129 is connected to the other end of the tilt lock member 128, and the other end of the link member 129 is connected to a position apart from the tilt axis 127c in the connection lock member 127. By the connection of the link member 129, in a state where the connection lock member 127 is disposed at the lock position a, the engagement pin 128a is engaged with the lock member engagement portion 126f or the engagement pin 128a is disposed at a position engageable with the lock member engagement portion 126 f. On the other hand, in the state where the coupling lock member 127 is disposed at the retracted position B, the engagement pin 128a and the lock member engagement portion 126f are not engaged with each other.
One end of an operating lever 130 as an operating member is connected to the other end side of the tilt lock member 128, and the operating lever 130 tilts about the tilt axis line 128b of the tilt lock member 128. As shown in fig. 1, 6, etc., since the other end of the operating lever 130 protrudes from the rear wheel side cover 120a of the rear wheel side vehicle body 120, the engagement between the engagement pin 128a and the lock member engagement portion 126f can be released and the coupling lock member 127 can be disposed at the retracted position B by tilting the operating lever 130 rearward or downward of the vehicle.
In the electric vehicle configured as described above, an example of a method of releasing the connection between the front wheel side vehicle body 110 and the rear wheel side vehicle body 120 will be described.
First, in a state where the seat unit 40 is detached from the rear wheel-side vehicle body 120, the handle portion 125c protruding from the upper end side of the back surface 33b of the seat support portion 33 is gripped with one hand, and the operating lever 130 is tilted rearward or downward of the vehicle while applying a force upward or rearward of the vehicle to the handle portion 125 c. This causes the following states: the engagement between the engagement pin 128a and the lock member engagement portion 126f is released, the connection lock member 127 is disposed at the retreat position B, and the 2 nd beam 113B is released from the 2 nd recess 121B.
When the rear wheel-side vehicle body 120 is tilted backward around the axle of the rear wheel 20 in this state, the auxiliary wheel 126b, which is the other end portion of the anti-toppling member 126, is grounded. When the rear wheel-side vehicle body 120 is further tilted backward around the axle of the rear wheel 20, the locking member engaging portion 126f of the anti-toppling member 126 engages with the cross member 124a at the 2 nd tilting position, and the upward tilting of the anti-toppling member 126 is restricted.
At this time, it is preferable that the position of the center of gravity of the rear-wheel-side vehicle body 120 is disposed between or near the ground contact position of the rear wheel 20 and the ground contact position of the auxiliary wheel 126b of the anti-toppling member 126 in the vehicle front-rear direction. This allows the rear wheel-side vehicle body 120 to be stably supported by the rear wheels 20 and the rollover prevention member 126.
On the other hand, when the rear wheel side vehicle body 120 tilts backward, the 1 st recessed portions 121a are opened diagonally upward, and therefore the 1 st cross member 113a of the front wheel side vehicle body 110 is stably supported by the 1 st recessed portions 121 a. Therefore, the front wheel side vehicle body 110 can be detached from the rear wheel side vehicle body 120 by separating the hand from the grip portion 125c, lifting the rear end side of the front wheel side vehicle body 110, and pulling out the 1 st cross member 113a from the 1 st recessed portion 121 a. At this time, the rear wheel-side vehicle body 120 is also stably supported by the rear wheel 20 and the anti-toppling member 126. After thus disassembled, the front-wheel-side vehicle body 110 and the rear-wheel-side vehicle body 120 are placed on an automobile or the like.
Next, an example of a method of coupling the front wheel side vehicle body 110 and the rear wheel side vehicle body 120 will be described.
First, in a state where the anti-toppling member 126 is disposed at the 2 nd tilted position, the auxiliary wheel 126b of the anti-toppling member 126 and the rear wheel 20 are grounded. In this state, the 1 st cross member 113a of the front wheel-side vehicle body 110 is put into the 1 st recessed portion 121 a. This causes the front wheel-side vehicle body 110 to be supported by the 1 st recessed portion 121a and the front wheel 10.
Next, the rear-wheel-side vehicle body 120 is tilted forward around the axle of the rear wheel 20. Thereby, as shown in fig. 10, the 2 nd cross member 113b abuts on the inclined surface 127b of the coupling lock member 127 from below. When the rear wheel-side vehicle body 120 is further tilted forward around the axle of the rear wheel 20 in this state, the coupling lock member 127 tilts forward of the vehicle, and the 2 nd cross member 113b enters the 2 nd recessed portion 121b. When the 2 nd cross member 113b enters the 2 nd recessed portion 121b, the coupling lock member 127 tilts toward the vehicle rear side by the biasing member 127d, and the coupling between the front wheel side vehicle body 110 and the rear wheel side vehicle body 120 is maintained by the coupling lock member 127.
In this way, according to the present embodiment, when the tilt restriction by the tilt lock member 128 is released by the operation lever 130, the anti-toppling member 126 tilts to the 2 nd tilting position above the 1 st tilting position, and is restricted from tilting upward by the cross member 124a at that position.
Therefore, when the auxiliary wheels 126b of the anti-toppling member 126 are grounded, the center of gravity position of the rear wheel-side vehicle body 120 is shifted rearward of the vehicle, and for example, the center of gravity position is disposed between the ground contact portions of the rear wheels 20 and the ground contact portions of the auxiliary wheels 126b, so that the rear wheel-side vehicle body 120 can be stably supported by the rear wheels 20 and the anti-toppling member 126.
In the present embodiment, when the coupling lock member 127 is moved to the retracted position B by the operating lever 130 and the locking of the coupling between the front wheel-side vehicle body 110 and the rear wheel-side vehicle body 120 is released, the tilt restriction by the tilt lock member 128 is released, and the tip-over prevention member 126 tilts to the 2 nd tilt position above the 1 st tilt position and is restricted from tilting upward by the cross member 124a at that position. Therefore, when the releasing operation of the coupling is to be performed, the rear wheel-side vehicle body 120 is in a state of being stably supported by the rear wheel 20 and the rollover prevention member 126, which is advantageous in that the releasing operation of the coupling is easily performed.
When the tilt lock member 128 is tilted, the coupling lock member 127 is also tilted by the link member 129. Therefore, when the releasing operation of the coupling is performed, the tilt restriction by the tilt lock member 128 is released in an interlocked manner, and the rear wheel-side vehicle body 120 can be stably supported by the rear wheels 20 and the rollover prevention member 126 easily and reliably. Further, when the operation lever 130 is fixed to the coupling lock member 127 and the coupling lock member 127 is tilted, the tilt lock member 128 may also be tilted by the link member 129.
Further, since the anti-overturn device 126, which is disposed at the 1 st inclination position when the front wheel-side vehicle body 110 and the rear wheel-side vehicle body 120 are connected to each other to prevent the electric motorcycle from overturning rearward, can be used to support the rear wheel-side vehicle body 120 from which the connection with the front wheel-side vehicle body 110 has been released, it is not necessary to provide a dedicated device for supporting the rear wheel-side vehicle body 120.
Further, by checking the tilting state of the tiltable lever 130 provided to the rear wheel-side vehicle body 120, the tilt restriction state by the tilt lock member 128 and the lock state by the coupling lock member 127 can be physically checked. Therefore, it is possible to prevent an unreasonable operation such as tilting the rear wheel side vehicle body 120 backward in a state where the tilt restriction by the tilt lock member 128 and the lock by the coupling lock member 127 are not released. When the front wheel side vehicle body 110 and the rear wheel side vehicle body 120 are coupled, the tilt restriction state by the tilt lock member 128 and the lock state by the coupling lock member 127 can be physically confirmed.
In addition, in a state where the upward tilting is restricted by the tilt locking member 128, the downward tilting of the falling prevention member 126 is restricted by the cross member 124a of the rear wheel side frame 121. When the tilt restriction by the tilt lock member 128 is released and the anti-toppling member 126 tilts to the 2 nd tilting position, the upward tilting of the anti-toppling member 126 is also restricted by the same cross member 124 a. Therefore, the structure for controlling the tilting of the anti-toppling member 126 can be made simple, which is advantageous in an electric vehicle that has a strong demand for weight reduction and a limited design space.
In the present embodiment, the tilt lock member 128 and the coupling lock member 127 are tilted by the operating lever 130, but it is also possible to couple the output shaft of the reduction gear to at least one of the tilt lock member 128 and the coupling lock member 127, and to drive the drive shaft of the reduction gear by a motor, for example. In this case, the controller 80 may be configured to control the motor 50 in response to the received lock release signal or lock signal.
In the present embodiment, the seat unit 40 is disassembled into the front-wheel-side vehicle body 110 and the rear-wheel-side vehicle body 120 after being detached from the vehicle main body 30. On the other hand, the seat unit 40 may be disassembled into the front-wheel-side vehicle body 110 and the rear-wheel-side vehicle body 120 without being disassembled. In the case where the seat unit 40 is not attached to the rear wheel-side vehicle body 120 but to the front wheel-side vehicle body 110, or in the case where the seat unit 40 is small, there is a case where it is not necessary to detach the seat unit 40.
In the present embodiment, the rollover prevention unit 126 is shown as protruding rearward of the vehicle with respect to the rear wheel 20, and the rollover prevention unit 126 is tilted upward to support the rear wheel-side vehicle body 120 by the auxiliary wheel 126b at the other end of the rollover prevention unit 126 and the rear wheel 20. In contrast, the anti-toppling member 126 may be a member without the auxiliary wheel 126 b. In this case, the electric vehicle can be prevented from falling backward by the fall prevention member 126, and the rear-wheel-side vehicle body 120 can be supported by the other end portion of the fall prevention member 126 and the rear wheel 20.
In the present embodiment, when the center of gravity of the rear wheel-side vehicle body 120 is located rearward of the vehicle with respect to the rotation axis 20a of the rear wheel 20, the anti-rollover member 126 may be configured so as to be provided with a protruding member protruding forward of the rear wheel-side vehicle body 120 without tilting upward of the 1 st tilting position.
In this case, one end of the protruding member is supported by the rear wheel-side vehicle body 120 and can tilt in the vertical direction. In the coupled state where the front wheel side vehicle body 110 and the rear wheel side vehicle body 120 are coupled, the projecting member is disposed at the 1 st tilting position so as to extend in the vehicle front-rear direction, for example. When the connection between the front wheel-side vehicle body 110 and the rear wheel-side vehicle body 120 is released, the projecting member can tilt to the 2 nd tilt position above the 1 st tilt position after the release of the connection. Thus, when the rear wheel-side vehicle body 120 is supported by the other end portion of the protruding member and the rear wheel 20, the center of gravity of the rear wheel-side vehicle body 120 is shifted toward the front of the vehicle than when coupled.
Further, the rear wheel side frame 121 may be provided with a cross member, an engagement pin, or the like extending in the vehicle width direction without the 1 st recess 121a, and the side members 112 of the front wheel side frame 111 may be provided with, for example, substantially U-shaped recesses opening obliquely downward toward the vehicle front direction without the 1 st cross member 113a, so that the cross member, the engagement pin, or the like of the rear wheel side frame 121 is engaged with the respective recesses.
Further, the rear wheel side frame 121 may be provided with a cross member, an engagement pin, and the like extending in the vehicle width direction without the 2 nd recessed portion 121b, the side members 112 of the front wheel side frame 111 may be provided with, for example, a substantially U-shaped recessed portion opening upward without the 2 nd cross member 113b, and the cross member, the engagement pin, and the like of the rear wheel side frame 121 may be engaged with the recessed portions. The front wheel-side vehicle body 110 and the rear wheel-side vehicle body 120 may be detachably coupled to each other by another method.
In the present embodiment, the case where the 1 st recessed portion 121a and the 2 nd recessed portion 121b having substantially U-shapes are provided in the rear wheel side frame 121 is shown. On the other hand, if the 1 st recessed portion 121a is a portion that is open toward the vehicle front side while coming into contact with the 1 st cross member 113a from below, above, and vehicle rear when the front-wheel-side vehicle body 110 and the rear-wheel-side vehicle body 120 are coupled, the same operational effects as described above can be obtained even if the 1 st recessed portion 121a has another shape. Further, as long as the 2 nd concave portion 121b is also a portion that is in contact with the 2 nd cross member 113b from above, behind, and in front of the vehicle and is open downward when the front wheel side vehicle body 110 and the rear wheel side vehicle body 120 are coupled, the same operational effects as described above can be obtained even if the 2 nd concave portion 121b is of another shape.
In the case where the concave portion that opens obliquely downward toward the vehicle front direction is provided in the front wheel side frame 111 as described above and the 1 st cross member 113a is not provided, the same operational effects as described above can be obtained even if the concave portion has another shape as long as the concave portion is a portion that opens obliquely downward toward the vehicle front direction from above, below, and the vehicle rear side, when the front wheel side vehicle body 110 is coupled to the rear wheel side vehicle body 120, such as a cross member or an engagement pin that contacts the rear wheel side vehicle body 120 from above.
In the case where the recessed portion that opens upward is provided in the front wheel side frame 111 as described above and the 2 nd cross member 113b is not provided, the same operational effects as described above can be obtained even if the recessed portion has another shape as long as the recessed portion is a portion that opens upward from below, behind the vehicle, and in front of the vehicle, when the front wheel side vehicle body 110 and the rear wheel side vehicle body 120 are coupled, and abuts against the cross member, the engagement pin, and the like of the rear wheel side vehicle body 120.
In the present embodiment, the case where the tilting of the anti-toppling member 126 to the position above the 2 nd tilting position is restricted by engaging the lock member engaging portion 126f of the tilting member 126a with the cross member 124a is shown. In contrast, a portion between the other end of the tilting member 126a and the tilting center 126d may be engaged with the rear wheel side cover 120a and the rear wheel side frame 121, thereby restricting the tilting of the anti-toppling member 126 to a position above the 2 nd tilting position. If the rear wheel-side vehicle body 120 can be supported by the rear wheels 20 and the anti-toppling member 126, the anti-toppling member 126 may be restricted from tilting to a position above the 2 nd tilting position by another structure.
