Summary of the Invention

Problems to be Solved by the Invention

[0004] A vehicle with a prime mover runs using the prime mover output, and attachment of a license plate is required. On the other hand, a bicycle that runs by the driver's pedaling force is often allowed to run even without a license plate.

[0005] If these vehicles with prime movers and pedal-driven vehicles have the same appearance, it is difficult for viewers existing outside the vehicle to distinguish which type of vehicle it is. For this reason, it is considered preferable to switch, for example, the display / shielding of the license plate in conjunction with the switching of the driving mode. Also, it is desirable that no malfunction occurs during the switching of the driving mode.

[0006] An object of the present disclosure is to provide a vehicle that can realize two driving modes and is less likely to cause an error in the switching operation of the driving mode.

Means for Solving the Problems

[0007] The problems to be solved by the present disclosure are as described above. Next, the means for solving this problem and its effects will be described.

[0008] According to a first aspect of the present disclosure, a vehicle having the following configuration is provided. That is, the vehicle includes a control unit, a display member, a shielding unit, a first operation member, and a second operation member. The control unit can switch the running mode of the vehicle between a driving mode in which the vehicle runs with power output by the prime mover and a suppression mode in which the output is suppressed compared to the output in the driving mode. Information for running in the driving mode is displayed on the display member. The shielding unit can shield at least a part of the display member. The first operation member is used for operating the shielding unit. The second operation member is used for operating the shielding unit. The shielding unit is movable between a shielding position that shields at least a part of the display of the information on the display member and a shielding release position that releases the shielding of the display. In conjunction with a shielding release operation for operating both the first operation member and the second operation member, the shielding unit moves from the shielding position to the shielding release position. The shielding portion includes a first shielding member and a second shielding member. The first operating member is connected to the first shielding member. The second operating member is connected to the second shielding member.

[0009] In this configuration, in order to release the shielding of the display on the display member, it is necessary to operate both the first operation member and the second operation member. Therefore, it is practically necessary to operate with both hands of the driver, so it is possible to prevent an unintended mode switch from occurring due to an erroneous operation or the like. Since the shielding unit moves in conjunction with the first operation member and the second operation member, the driver only needs to operate the first operation member and the second operation member, and the mode switching operation is easy. A simple configuration in which the shielding portion interlocks with the first operating member and the second operating member can be realized.

[0010] According to a second aspect of the present disclosure, a vehicle having the following configuration is provided. That is, the vehicle includes a control unit, a display member, and a shielding unit. The control unit can switch the traveling mode of the vehicle between a driving mode in which the vehicle travels with the power output by the prime mover and a suppression mode in which the output is suppressed compared to the output in the driving mode. The display member displays information for traveling in the driving mode. The shielding unit can shield at least a part of the display member. The display member is arranged such that a display surface on which the information is displayed is visible from the rear of the vehicle. The shielding unit is movable between a shielding position where at least a part of the display of the information on the display member is shielded and a shielding release position where the shielding of the display is released. The shielding unit covers the display surface from the rear at the shielding position. The shielding unit moves forward while passing at least one of the left or right of the display member in the process of moving from the shielding position to the shielding release position.

[0011] Thereby, since the shielding unit moves clearly between the shielding position and the shielding release position, it is possible to effectively prevent an erroneous operation during mode switching.

Effects of the Invention

[0012] According to the present disclosure, it is possible to realize two traveling modes and provide a vehicle in which an erroneous operation is less likely to occur in the traveling mode switching operation.

Embodiments for Carrying Out the Invention

[0014] Next, embodiments disclosed will be described with reference to the drawings. First, referring to FIGS. 1 and 2, an overview of a three-wheeled vehicle 1 according to an embodiment of the present disclosure will be described. FIG. 1 is a perspective view of a three-wheeled vehicle 1 according to an embodiment of the present disclosure. FIG. 2 is a block diagram showing an electrical configuration of the three-wheeled vehicle 1.

[0015] In the following description, the left-right direction of the three-wheeled vehicle 1 is defined in the direction seen from the driver riding on the three-wheeled vehicle 1. Therefore, in a state where the three-wheeled vehicle 1 is upright as shown in FIG. 1, the front-rear direction coincides with the vehicle length direction, and the left-right direction coincides with the vehicle width direction. Also, the up-down direction (vertical direction) coincides with the height direction.

[0016] The three-wheeled vehicle (vehicle) 1 of the present embodiment includes two front wheels 2 and 3 on the front side (one side in the vehicle length direction) and one rear wheel 4 on the rear side (the other side in the vehicle length direction).

[0017] The three-wheeled vehicle 1 includes a vehicle body 10. The vehicle body 10 supports a left front wheel 2, a right front wheel 3, and a rear wheel 4.

[0018] The vehicle body 10 includes a frame 11 that serves as the skeleton of the three-wheeled vehicle 1. The frame 11 has a base portion 11a, left and right wheel connecting portions 11b, a seat support portion 11c, and a handle support portion 11d.

[0019] The base portion 11a extends in the vehicle length direction between the front wheels 2, 3 and the rear wheel 4 and supports the front and rear wheels. The left and right wheel connecting portions 11b are connected to the base portion 11a, connect the left front wheel 2 and the right front wheel 3, and extend in the vehicle width direction. The seat support portion 11c extends upward from the base portion 11a and supports the seat 15. The handle support portion 11d extends upward from the base portion 11a and supports the handle 12.

[0020] In the present embodiment, the three-wheeled vehicle 1 is a type of leaning vehicle. A leaning vehicle means a vehicle in which the posture of the vehicle body 10 with respect to the road surface can be changed, and the vehicle body 10 is in an inclined state with respect to the road surface as it turns by steering. In FIG. 1, the three-wheeled vehicle 1 is in a state where the handle 12 for steering is operated to the neutral position and the vehicle body 10 is upright with respect to the road surface (in other words, in a normal straight-ahead driving state). Hereinafter, unless otherwise specified, the description will be based on this state.

[0021] The left front wheel 2 and the right front wheel 3 are arranged adjacent to each other with a space therebetween in the vehicle width direction. In the present embodiment, each of the front wheels 2, 3 functions as a driven wheel. The left front wheel 2 and the right front wheel 3 are supported at the front portion of the frame 11 so that the posture of the vehicle body 10 with respect to the road surface can be changed. Each of the front wheels 2, 3 functions as a steering wheel and changes its direction according to the rotation operation of the handle 12.

[0022] The left and right wheel connection parts 11b of the frame 11 have a known parallel link structure. The parallel link structure connects each of the front wheels 2 and 3 to the base part 11a of the frame 11 respectively. Due to this parallel link structure, in a front view, according to the change in the posture of the base part 11a, the postures of the front wheels 2 and 3 change in conjunction with each other.

[0023] The rear wheel 4 is disposed at the central position of the vehicle body 10 in the vehicle width direction. The rear wheel 4 is rotatably supported at the rear part of the frame 11. In the present embodiment, the rear wheel 4 functions as a driving wheel that transmits the driving force for running to the road surface.

[0024] The three-wheeled vehicle 1 includes a seat 15, left and right pedals 16, an electric motor 21 that functions as a prime mover, a battery 22, and a controller (control unit) 23.

[0025] The seat 15 is provided on the upper side of the intermediate part in the vehicle length direction of the frame 11. The driver can sit astride the seat 15 and place their feet on the left and right pedals 16.

[0026] The left and right pedals 16 are provided below the seat 15. The force applied by the driver sitting astride the seat 15 and stepping on the pedals 16 with their feet can be transmitted to the rear wheel 4, and the rear wheel 4 can be rotationally driven manually. Therefore, the three-wheeled vehicle 1 is provided with a mechanism as a so-called bicycle that is driven to run by the driver's manual power.

[0027] In the present embodiment, the electric motor 21 is provided on the axle part of the rear wheel 4. As shown in FIG. 2, the electric motor 21 is electrically connected to the controller 23. The electric motor 21 is controlled by the controller 23 and can rotationally drive the rear wheel 4.

[0028] The electric motor 21 can drive the drive wheels in a state where no driver's manual input is given. Also, the electric motor 21 can drive the drive wheels so as to assist the driver's manual input. The controller 23 adjusts the output of the electric motor 21 by giving an appropriate command to the electric motor 21. In the present embodiment, the controller 23 controls the electric motor 21 to output a driving force and assist according to the manual input given by the driver. That is, in the present embodiment, the three-wheeled vehicle 1 functions as an electric vehicle that can travel without the driver's manual input and also functions as an electric assist bicycle that electrically assists the driving by the driver.

[0029] The three-wheeled vehicle 1 of the present embodiment can switch between two driving modes: an electric vehicle mode that does not require the driver's manual input and a bicycle mode that requires the driver's manual input. When the two driving modes are switched, the control that the controller 23 performs on the electric motor 21 changes.

[0030] In the electric vehicle mode, it travels with the power output by the electric motor 21 which is the prime mover. In the bicycle mode, the output of the electric motor 21 is suppressed as compared with the electric vehicle mode. The electric vehicle mode is an example of a driving mode. The bicycle mode is an example of a suppression mode.

[0031] In the bicycle mode, compared with the electric vehicle mode, the output may be suppressed only in a part rather than the entire usable range. In the bicycle mode, for example, the maximum output output by the electric motor 21 may be suppressed, or the maximum vehicle speed at which the electric motor 21 can travel may be suppressed. In the bicycle mode, when the vehicle speed exceeds a predetermined vehicle speed, the assistance ratio of the electric motor 21 with respect to the manual input may decrease. In the bicycle mode, the vehicle speed range in which the electric motor 21 can operate may be set lower than that in the electric vehicle mode. In the bicycle mode, the electric motor 21 may be suppressed so as not to generate any power and become zero.

[0032] In the electric vehicle mode, the output is set so that the three-wheeled vehicle 1 can satisfy the output conditions for running as an electric vehicle. In the bicycle mode, the output is set so that the three-wheeled vehicle 1 can satisfy the output conditions for running as a bicycle, specifically an electric assist bicycle in this embodiment.

[0033] The battery 22 is provided on the lower side of the middle part in the front and rear of the frame 11. The battery 22 can supply power to the electric motor 21, the controller 23, and various auxiliary devices and the like.

[0034] The controller 23 is provided at an appropriate position of the vehicle body 10. The controller 23 is composed of a known computer and can control the electric motor 21.

[0035] The carrier 17 can carry loads. The carrier 17 is behind the seat 15 provided behind the handle 12 and above the rear wheel 4. The carrier 17 is attached to the rear part of the frame 11. A license light 18 is arranged at the rear end of the carrier 17.

[0036] The three-wheeled vehicle 1 is equipped with an operator that can be operated by hand, for example, by the driver. Although not shown in the drawings, the operator is arranged near the handle 12, for example. When the three-wheeled vehicle 1 runs in the electric vehicle mode, the electric motor 21 is controlled when the driver operates the operator. On the other hand, when the three-wheeled vehicle 1 runs in the bicycle mode, the electric motor 21 is controlled based on the driver's pedaling force.

[0037] As shown in FIG. 2, the three-wheeled vehicle 1 includes an accelerator sensor 81 and a brake sensor 82. The operation of the aforementioned operator is detected by appropriate sensors such as the accelerator sensor 81 and the brake sensor 82. The three-wheeled vehicle 1 is provided with a vehicle speed sensor 83 and a meter 84. The meter 84 can display at least the above-described traveling mode (travel mode) and the state of the battery 22. The state of the battery 22 can be detected by a battery state sensor 86. The three-wheeled vehicle 1 is further provided with a sensor (for example, a pedaling force sensor 87) for calculating the assist amount in the assist bicycle mode.

[0038] The three-wheeled vehicle 1 includes a mode switching sensor (detection unit) 91. In the present embodiment, the mode switching sensor 91 functions as a switch for switching the traveling mode. When the mode switching sensor 91 detects that the shielding portion 50 described later is in the shielding release position where it does not cover the display surface of the license plate 32, it gives an electric vehicle mode command to the controller 23. When the mode switching sensor 91 detects that the shielding portion 50 is in the shielding position where it covers the display surface of the license plate 32, it gives a bicycle mode command to the controller.

[0039] The controller 23 includes a mode determination unit 96, a motor command output unit 97, and a motor drive circuit 98.

[0040] The mode determination unit 96 determines the traveling mode to be selected based on the detection value of the mode switching sensor 91.

[0041] In the case of the electric vehicle mode, the motor command output unit 97 calculates a motor command based on the detection values of the accelerator sensor 81 and the brake sensor 82. At this time, the motor command may be corrected based on the vehicle speed, the state of the battery 22, the state of the electric motor 21, and the like.

[0042] In the case of the bicycle mode, the motor command output unit 97 calculates a motor command based on the detected value of the pedaling force sensor 87. The motor command may be corrected based on the vehicle speed, the state of the battery 22, and the state of the electric motor 21. In the bicycle mode, either the maximum vehicle speed or the maximum output by the drive of the electric motor 21 is limited compared to the electric vehicle mode. In the bicycle mode, the motor command output unit 97 may generate a motor command based on the detection information of the operation of the operator, similarly to the electric vehicle mode. In this case, even if the same command is given, the motor command output unit 97 generates a suppressed motor command compared to the electric vehicle mode.

[0043] The motor drive circuit 98 is configured as a power supply circuit. The motor drive circuit 98 supplies power corresponding to the motor command given from the motor command output unit 97 to the electric motor 21.

[0044] The three-wheeled vehicle 1 includes a number plate device 31 for identifying its traveling mode from the surroundings (outside) of the three-wheeled vehicle 1. The number plate device 31 is disposed at the rear end of the vehicle body 10. The number plate device 31 can indicate the current traveling mode of the three-wheeled vehicle 1 to the surroundings.

[0045] As shown in FIG. 1, the number plate device 31 is disposed behind the seat 15 with the loading platform 17 interposed therebetween, and is provided below the loading platform 17.

[0046] As shown in FIGS. 3 and 4, the number plate device 31 includes a base plate 40, a first link member 41, a second link member 42, a first cover 43, a second cover 44, and a protection cover 45. The first cover 43 corresponds to a first shielding member. The second cover 44 corresponds to a second shielding member. The first cover 43 and the second cover 44 constitute a shielding portion 50. The shielding portion 50 can shield a part of the back surface of the number plate 32.

[0047] The base plate 40 is fixed to the rear end portion of the loading platform 17 via members such as brackets (not shown). The base plate 40 is formed in a plate shape. The base plate 40 is arranged such that one surface in the thickness direction faces rearward, precisely diagonally upward to the rear. The surface of the base plate 40 facing rearward also functions as an attachment surface to which the number plate (display member) 32 is attached.

[0048] The number plate 32 is installed on the vehicle in order to permit the vehicle to run as an electric vehicle. An individual identification number (identification information) of the vehicle is attached to the number plate 32. The number plate 32 is fixed to the base plate 40 such that the display surface, which is the surface with the identification number attached, faces rearward.

[0049] The first hinge base 51 and the second hinge base 52 are fixed to the surface of the base plate 40 facing forward. The first link member 41 is rotatably supported by the first hinge base 51. The second link member 42 is rotatably supported by the second hinge base 52. The first link member 41 and the second link member 42 are arranged in front of the base plate 40.

[0050] As shown in FIG. 4, the first link member 41 is composed of two arc-shaped elongated plates. The two plates are formed in substantially the same shape and are arranged at intervals in the vertical direction. One end in the longitudinal direction of the first link member 41 is supported by the first hinge base 51 via a support shaft 53. A first cover 43 is rotatably supported via a cover support shaft 55 at the end of the first link member 41 on the side far from the support shaft 53. The support shaft 53 and the cover support shaft 55 are arranged to face in the vertical direction and are oriented parallel to the base plate 40.

[0051] As shown in FIG. 4, the second link member 42 is composed of two arc-shaped elongated plates. The two plates are formed in substantially the same shape and are arranged at intervals in the vertical direction. One end of the second link member 42 in the longitudinal direction is supported by the second hinge base 52 via the support shaft 54. A second cover 44 is rotatably supported at the end of the second link member 42 on the side far from the support shaft 54 via the cover support shaft 56. The support shaft 54 and the cover support shaft 56 are arranged to face the vertical direction and are oriented parallel to the base plate 40.

[0052] The first link member 41 includes a round bar-shaped connecting rod 60 that connects the two plates. The connecting rod 60 is oriented parallel to the support shafts 53 and 54. Curved elongated interlocking grooves 61 are formed through each of the two plates of the second link member 42. The connecting rod 60 is inserted into the interlocking groove 61.

[0053] The first cover 43 is a plate-shaped member. The first cover 43 is formed by being bent in an L shape when viewed along the cover support shaft 55. The vicinity of the bent portion of the first cover 43 is supported by the tip of the first link member 41 by the cover support shaft 55.

[0054] The second cover 44 is a plate-shaped member. The second cover 44 is formed by being bent in an L shape when viewed along the cover support shaft 56. The vicinity of the bent portion of the second cover 44 is supported by the tip of the second link member 42 by the cover support shaft 56.

[0055] The first cover 43 and the second cover 44 are formed symmetrically. Each of the first cover 43 and the second cover 44 includes a shielding plate (shielding body) 63 and a rotation restricting portion 64. Both the shielding plate 63 and the rotation restricting portion 64 are formed in a flat plate shape. The shielding plate 63 and the rotation restricting portion 64 are connected to each other via a bent portion.

[0056] The shielding plate 63 is formed in a horizontally elongated plate shape. The length of the shielding plate 63 in the longitudinal direction is approximately equal to half of the left - right width of the base plate 40. The shielding plates 63 provided on the first cover 43 and the second cover 44 can be positioned behind the number plate 32 so as to be close to the display surface of the number plate 32 as shown in FIGS. 5 and 6. At this time, each shielding plate 63 hides the display of the number plate 32 over half of the left - right width. As shown in FIG. 5, by arranging the first cover 43 and the second cover 44 side by side while being close to each other in the left - right direction to cover the display surface of the number plate 32, the display of the number plate 32 can be blocked.

[0057] As shown in FIG. 4, in the shielding plate 63 of the first cover 43, a first operation member 46 is fixed to the end portion on the side far from the cover support shaft 55. In the shielding plate 63 of the second cover 44, a second operation member 47 is fixed to the end portion on the side far from the cover support shaft 56. The first operation member 46 and the second operation member 47 are each formed in a loop shape.

[0058] In the state of FIG. 5 where the first cover 43 and the second cover 44 shield the display of the number plate 32, the first operation member 46 and the second operation member 47 are located at the left - right center of the base plate 40. In this state, the first operation member 46 and the second operation member 47 protrude rearward from the first cover 43 and the second cover 44.

[0059] In the state of FIG. 3 where the first cover 43 and the second cover 44 are retracted without shielding the display of the number plate 32, the first operation member 46 and the second operation member 47 are arranged so as to protrude outward to the left and right from the vicinity of the left - right ends of the base plate 40.

[0060] For example, in the state of FIG. 5, the driver can hold the first operating member 46 with the right hand and the second operating member 47 with the left hand respectively. In this state, the driver can operate to open and close the first cover 43 and the second cover 44 in the left - right direction with both hands. Also, the driver can operate to pull out the first cover 43 and the second cover 44, which are in the open state to the left and right, backward or push them forward.

[0061] Hereinafter, the direction in which the first cover 43 and the second cover 44 are opened away from each other around the cover support shafts 55, 56 may be referred to as the opening direction. Also, the direction in which the first cover 43 and the second cover 44 are closed toward each other around the cover support shafts 55, 56 may be referred to as the closing direction. The names of the opening direction and the closing direction may also be used with respect to the operating directions of the first operating member 46 and the second operating member 47.

[0062] Hook portions 70 are provided at the left and right ends of the upper front portion of the base plate 40. Each hook portion 70 has an open front. By inserting the first operating member 46 or the second operating member 47 into the hook portion 70 from the front, the first operating member 46 and the second operating member 47 can be fixed in a state of being hooked on the hook portion 70.

[0063] The rotation restricting portion 64 is formed in a plate shape. The rotation restricting portion 64 of the first cover 43 restricts the first cover 43 from rotating too much in the opening direction by hitting the edges of the two plates of the first link member 41. The rotation restricting portion 64 of the second cover 44 restricts the second cover 44 from rotating too much in the opening direction by hitting the edges of the two plates of the second link member 42.

[0064] Elastic members 76 and 77 are attached to the first link member 41 and the second link member 42. The elastic members 76 and 77 are configured as, for example, torsion coil springs. The elastic member 76 attached to the first link member 41 constantly acts on the first link member 41 with a force to rotate it in a direction approaching the base plate 40. The elastic member 77 attached to the second link member 42 constantly acts on the second link member 42 with a force to rotate it in a direction approaching the base plate 40.

[0065] Elastic members 78 and 79 are attached to the first cover 43 and the second cover 44. The elastic members 78 and 79 are configured as, for example, torsion coil springs. The elastic member 78 attached to the first cover 43 constantly acts on the first cover 43 with a force to rotate it in the closing direction. The elastic member 79 attached to the second cover 44 constantly acts on the second cover 44 with a force to rotate it in the closing direction. The elastic member 78 and the elastic member 79 constitute a restoring force imparting structure.

[0066] A switch mount 75 is fixed at a position on the front surface of the base plate 40 between the first hinge base 51 and the second hinge base 52. A mode switching sensor 91 is fixed at an appropriate position of the switch mount 75. The mode switching sensor 91 is located in front of the base plate 40. The mode switching sensor 91 is configured as a push switch having a mover.

[0067] As the first link member 41 rotates about the support shaft 53, the connecting rod 60 moves along an arc-shaped locus. The mode switching sensor 91 can detect a state in which the first link member 41 has rotated forward by a sufficient angle through the mover being pushed by the connecting rod 60.

[0068] The first link member 41 and the second link member 42 are connected to each other via a connecting rod 60 and an interlocking groove 61.

[0069] The interlocking groove 61 is formed as follows. That is, when attempting to rotate only the first link member 41 forward about the support shaft 53 from the state where both the first link member 41 and the second link member 42 are close to the base plate 40 as shown in FIG. 7 due to the action of the elastic members 76 and 77, the movement locus of the connecting rod 60 does not coincide with the interlocking groove 61. Similarly, when attempting to rotate only the second link member 42 forward about the support shaft 54, the relative movement locus of the connecting rod 60 does not coincide with the interlocking groove 61. On the other hand, when the first link member 41 and the second link member 42 are simultaneously rotated forward at substantially the same angular velocity, the connecting rod 60 relatively moves along the longitudinal direction of the interlocking groove 61.

[0070] In the configuration of the present embodiment, even if only the first link member 41 or only the second link member 42 is rotated forward, it is difficult because significant friction occurs between the outer peripheral surface of the connecting rod 60 and the inner wall surface of the interlocking groove 61. Thus, the connecting rod 60 and the interlocking groove 61 constitute a blocking mechanism 67 for preventing the shielding release operation when an operating force is applied to one of the first operating member 46 and the second operating member 47 and no operating force is applied to the other. In practice, the driver needs to hold the first operating member 46 and the second operating member 47 respectively and rotate both the first link member 41 and the second link member 42 via the first cover 43 and the second cover 44. Since such two-handed operation is forced, the driver can be surely made aware of the operation, and inadvertent operation can be prevented.

[0071] As shown in FIG. 4, at the midpoint in the longitudinal direction of the interlocking groove 61 formed in the second link member 42, a convex portion 71 is formed on the inner wall closer to the tip of the first link member 41, and a convex portion 72 is formed on the inner wall closer to the support shaft 53. Since the convex portions 71 and 72 are small, the convex portions 71 and 72 are not shown in FIGS. 6 and later.

[0072] Although it is not impossible to rotate only the first link member 41 forward with a large operating force exceeding the aforementioned surface friction, even in this case, the connecting rod 60 gets caught on the convex portion 71 during the operation. In order for the connecting rod 60 to cross over the convex portion 71, it is necessary to rotate the second link member 42 forward so that the convex portion 71 moves away from the connecting rod 60.

[0073] Similarly, when only the second link member 42 is rotated forward, the connecting rod 60 gets caught on the convex portion 72 during the operation. In order for the connecting rod 60 to cross over the convex portion 72, it is necessary to rotate the first link member 41 forward so that the connecting rod 60 moves away from the convex portion 72.

[0074] In this way, the two convex portions 71, 72 formed in the interlocking groove 61 can surely force the driver to operate with both hands.

[0075] Hereinafter, a state where both the first link member 41 and the second link member 42 are close to the base plate 40 as shown in FIGS. 6 and 7 is sometimes referred to as a folded state, and a state where the first link member 41 and the second link member 42 are separated from the base plate 40 as shown in FIG. 8 is sometimes referred to as an unfolded state. In the unfolded state, operations such as hanging and removing the first operating member 46 and the second operating member 47 with respect to the hook portion 70 can be performed. The shielding positions of the first cover 43 and the second cover 44 shown in FIGS. 5 and 6 correspond to the folded state of the first link member 41 and the second link member 42. The shielding release positions of the first cover 43 and the second cover 44 shown in FIGS. 3, 4, and 9 correspond to a state where the first link member 41 and the second link member 42 are slightly returned from the unfolded state to the folded state.

[0076] The convex portion 71 and the convex portion 72 are arranged at positions in the interlocking groove 61 where the connecting rod 60 passes on the way from the folded state of FIG. 7 to the unfolded state of FIG. 8. Thereby, it is extremely difficult for the driver to operate the first cover 43 and the second cover 44 with one hand from the shielding position to the shielding release position.

[0077] As shown in FIG. 4, when the first cover 43 and the second cover 44 do not shield the display of the number plate 32 and most of them are located inside the protection cover 45, the connecting rod 60 of the first link member 41 presses the mover of the mode switching sensor 91. As a result, the controller 23 enters the electric vehicle mode.

[0078] As shown in FIG. 6 and the like, when the first cover 43 and the second cover 44 shield the display of the number plate 32, the connecting rod 60 moves away from the mover of the mode switching sensor 91. As a result, the controller 23 enters the bicycle mode.

[0079] The protection cover 45 is arranged to cover the front surface of the base plate 40. The protection cover 45 is formed in a hollow shape, and inside it, the first link member 41, the second link member 42, the connecting rod 60, the mode switching sensor 91, etc. are arranged. Thereby, the blocking mechanism 67, the resilience imparting structure, etc. can be protected. Also, unauthorized access to the mode switching sensor 91 can be prevented.

[0080] A cover bracket 48 is fixed to the front surface of the base plate 40. The protection cover 45 is fixed to the base plate 40 by an appropriate fixing member such as a screw via the cover bracket 48. As the fixing member of the protection cover 45, a component that is difficult to remove unless a special method is used can also be used. For example, as the fixing member, a screw that cannot be removed unless a special tool is used can be used. Thereby, unauthorized modification, etc. can be prevented.

[0081] Next, the operation when switching the first cover 43 and the second cover 44 provided in the shielding portion 50 from the shielding position to the shielding release position will be described. Hereinafter, this operation may be referred to as a shielding release operation.

[0082] When the driver wishes to remove the shielding of the license plate 32, the driver holds the first operating member 46 and the second operating member 47 in Fig. 6 with the left and right hands respectively, and rotates them in the opening direction as shown by the thick arrows in Fig. 6. As a result, the entire license plate 32 can be brought into the state shown in Fig. 7 where it is exposed. Subsequently, the driver pushes both the first operating member 46 and the second operating member 47 forward as shown by the thick arrows in Fig. 7. As a result, the state shown in Fig. 8 can be achieved.

[0083] Next, the driver rotates the first operating member 46 and the second operating member 47 slightly in the closing direction and hooks them on the pair of left and right hook portions 70 respectively. After that, the driver releases the hands from the first operating member 46 and the second operating member 47. Due to the action of the elastic members 76, 77, the first link member 41 and the second link member 42 tend to rotate in the direction approaching the base plate 40, but this rotation is blocked by the first cover 43 and the second cover 44 stretching between the cover pivot shafts 55, 56 and the hook portions 70. As described above, the first cover 43 and the second cover 44 can be held at the shielding removal position shown in Fig. 9.

[0084] In this way, the shielding removal operation includes the step of operating both the first operating member 46 and the second operating member 47. For example, as shown in Fig. 7, in the shielding removal operation, with the first operating member 46 and the second operating member 47 positioned apart from each other so as to sandwich the license plate 32 in a rear view, the operation of simultaneously pushing the first operating member 46 and the second operating member 47 forward is essential. Therefore, it is possible to strongly prompt the driver to operate with both hands.

[0085] In the present embodiment, as shown in Fig. 3 and the like, a license light 18 is arranged above the license plate 32, and a reflecting member 19 is arranged below the license plate 32. In this regard, by the operation shown in Fig. 7, the first cover 43 and the second cover 44 in the shielding position move forward while separating in the left - right direction and passing through both the left and right sides of the license plate 32 to reach the shielding removal position. In this process, the first operating member 46 and the second operating member 47 pass near both the left and right ends of the license plate 32.

[0086] Therefore, it is possible to realize a configuration in which the first cover 43, the second cover 44, the first operating member 46, and the second operating member 47 are less likely to interfere with the upper and lower parts of the number plate 32. In addition, since the movement of the first cover 43 and the second cover 44 between the shielding position and the shielding release position is easily visible, it is possible to prevent an erroneous operation during mode switching.

[0087] Next, the operation when switching the first cover 43 and the second cover 44 provided in the shielding portion 50 from the shielding release position to the shielding position will be described. Hereinafter, this operation may be referred to as a shielding operation.

[0088] When the driver wishes to shield the number plate 32, the driver holds the first operating member 46 and the second operating member 47 in FIGS. 9 with the left and right hands respectively, and as shown by the thick arrow in FIG. 10, after pushing it slightly forward, it is rotated slightly in the opening direction. Thereby, the first operating member 46 and the second operating member 47 can be removed from the left and right hook portions 70.

[0089] When the first operating member 46 and the second operating member 47 are pushed forward, the connecting rod 60 passes through the convex portions 71, 72 in the interlocking groove 61. Therefore, when the driver tries to push only one of the first operating member 46 and the second operating member 47 forward, the operation is blocked because the connecting rod 60 is caught by one of the two convex portions 71, 72.

[0090] Thereafter, the driver pulls out the first operating member 46 and the second operating member 47 backward, and then operates in the closing direction. Thereby, the first cover 43 and the second cover 44 can be moved to the shielding position shown in FIG. 6.

[0091] The driver can also release their hands from the first operating member 46 and the second operating member 47 while removing the first operating member 46 and the second operating member 47 held by hand from the left and right hook portions 70. Due to the action of the elastic members 76 and 77, the first link member 41 and the second link member 42 rotate in a direction approaching the base plate 40. Further, due to the action of the elastic members 78 and 79, the first cover 43 and the second cover 44 rotate in the closing direction. Thus, the first cover 43 and the second cover 44 can be moved to the shielding position shown in FIG. 6.

[0092] All of the elastic members 76, 77, 78, and 79 provided in the license plate device 31 always act with a force to move the first cover 43 and the second cover 44 to the shielding position. Therefore, it has become difficult to hold the first cover 43 and the second cover 44 at an intermediate position between the shielding position and the shielding release position. Thereby, erroneous operation can be prevented.

[0093] The seating surface of the seat 15 provided in the three-wheeled vehicle 1 is disposed in front of the axle of the rear wheel 4. The first operating member 46 and the second operating member 47 are disposed lower than the seating surface of the seat 15 and behind the axle of the rear wheel 4. Furthermore, the first operating member 46 and the second operating member 47 are disposed behind the rear end portion of the rear wheel 4. Thereby, it becomes extremely difficult for the driver to perform the shielding release operation by stretching their hand backward while sitting forward on the seat 15. Therefore, it is possible to strongly encourage the driver to perform the shielding release operation while getting off the three-wheeled vehicle 1.

[0094] As described above, the three-wheeled vehicle 1 of the present embodiment includes a controller 23, a number plate 32, a shielding portion 50, a first operation member 46, and a second operation member 47. The controller 23 can switch the traveling mode of the three-wheeled vehicle 1 between a driving mode in which the vehicle travels with the power output by the electric motor 21 and a suppression mode in which the output is suppressed compared to the output in the driving mode. Information for traveling in the driving mode is displayed on the number plate 32. The shielding portion 50 can shield at least a part of the number plate 32. Each of the first operation member 46 and the second operation member 47 is used to operate the shielding portion 50. The shielding portion 50 is movable between a shielding position that shields at least a part of the information display on the number plate 32 and a shielding release position that releases the shielding of the display. In conjunction with a shielding release operation of operating both the first operation member 46 and the second operation member 47, the shielding portion 50 moves from the shielding position to the shielding release position.

[0095] Thereby, in order to release the shielding of the display on the number plate 32, it is necessary to operate both the first operation member 46 and the second operation member 47. Therefore, since it is practically necessary to operate with both hands of the driver, it is possible to prevent an unintended mode switch from occurring due to an incorrect operation or the like. Since the shielding portion 50 moves in conjunction with the first operation member 46 and the second operation member 47, the driver only needs to operate the first operation member 46 and the second operation member 47, and the mode switching operation is easy.

[0096] In the three-wheeled vehicle 1 of the present embodiment, in the shielding release operation, both the first operation member 46 and the second operation member 47 located at positions separated from each other are operated.

[0097] Thereby, it becomes more difficult to operate with only one hand of the driver, and it is possible to suppress an unintended mode switch from occurring due to an incorrect operation or the like.

[0098] In the three-wheeled vehicle 1 of the present embodiment, as shown in FIGS. 7 and 8, the shielding release operation includes the simultaneous operation of the first operation member 46 and the second operation member 47 in a state where the first operation member 46 and the second operation member 47 are positioned so as to sandwich the license plate 32 in a rear view.

[0099] This makes it more difficult for the driver to operate with only one hand, and can suppress the occurrence of unintended mode switching due to incorrect operation or the like.

[0100] In the three-wheeled vehicle 1 of the present embodiment, in the shielding release operation, a blocking mechanism 67 is provided that blocks the shielding release operation when an operating force is applied to one of the first operation member 46 and the second operation member 47 and no operating force is applied to the other.

[0101] Thereby, it is possible to prevent the driver from operating with only one hand.

[0102] In the three-wheeled vehicle 1 of the present embodiment, the blocking mechanism 67 is located on the side opposite to the display surface on which information is displayed, rather than the license plate 32.

[0103] Thereby, unauthorized access to the blocking mechanism 67 can be prevented.

[0104] The three-wheeled vehicle 1 of the present embodiment includes a protective cover 45 that covers the side opposite to the display surface of the license plate 32. The blocking mechanism 67 is disposed inside the protective cover 45.

[0105] Thereby, a configuration in which unauthorized access to the blocking mechanism 67 is made more difficult can be realized.

[0106] In the three-wheeled vehicle 1 of the present embodiment, the first operation member 46 is movable between a first shielding operation position (FIG. 6) corresponding to the shielding position and a first shielding release operation position (FIG. 9) corresponding to the shielding release position. The second operation member 47 is movable between a second shielding operation position (FIG. 6) corresponding to the shielding position and a second shielding release operation position (FIG. 9) corresponding to the shielding release position. The number plate device 31 includes a restoring force imparting structure composed of elastic members 76, 77, 78, and 79. The restoring force imparting structure imparts a restoring force in a direction to move the first operation member 46 to the first shielding operation position and imparts a restoring force in a direction to move the second operation member 47 to the second shielding operation position.

[0107] As a result, since it is difficult to hold the first operation member 46 and the second operation member 47 at the intermediate position, erroneous operations can be reliably prevented.

[0108] In the three-wheeled vehicle 1 of the present embodiment, the shielding portion 50 includes a first cover 43 and a second cover 44. The first operation member 46 is connected to the first cover 43. The second operation member 47 is connected to the second cover 44.

[0109] As a result, a simple configuration in which the shielding portion 50 interlocks with the first operation member 46 and the second operation member 47 can be realized.

[0110] In the three-wheeled vehicle 1 of the present embodiment, the number plate 32 is arranged such that the display surface on which information is displayed is visible from the rear of the three-wheeled vehicle 1. The shielding portion 50 is behind the number plate 32 in the shielding position. The first cover 43 constituting the shielding portion 50 moves forward while passing to the right of the number plate 32 in the process of moving from the shielding position to the shielding release position. The second cover 44 constituting the shielding portion 50 moves forward while passing to the left of the number plate 32 in the process of moving from the shielding position to the shielding release position.

[0111] As a result, interference of the shielding portion 50 with components (for example, lighting that illuminates the display surface) above or below the number plate 32 can be prevented.

[0112] In the three-wheeled vehicle 1 of the present embodiment, the shielding release operation includes, for example, as shown in FIG. 6, simultaneous operations of the first operation member 46 and the second operation member 47 in different directions from each other.

[0113] This makes it more difficult for the driver to operate with only one hand, and can suppress the occurrence of unintended mode switching due to incorrect operation or the like.

[0114] In the three-wheeled vehicle 1 of the present embodiment, the shielding member 50 moves from the shielding release position to the shielding position by the shielding operation of simultaneously operating the first operation member 46 and the second operation member 47. The shielding operation includes, as shown in FIG. 10, simultaneous operations of the first operation member 46 and the second operation member 47 in a state where the first operation member 46 and the second operation member 47 are positioned so as to sandwich the number plate 32 in a rear view.

[0115] Thus, even when the display on the number plate 32 is shielded, it is necessary for the driver to operate with both hands. Therefore, it is possible to prevent unintended mode switching from occurring due to incorrect operation or the like of the first operation member 46 and the second operation member 47.

[0116] The three-wheeled vehicle 1 of the present embodiment includes a controller 23, a license plate 32, and a shielding portion 50. The controller 23 can switch the running mode of the three-wheeled vehicle 1 between a driving mode in which the vehicle runs with the power output from the electric motor 21 and a suppression mode in which the output is suppressed compared to the output in the driving mode. Information for running in the driving mode is displayed on the license plate 32. The shielding portion 50 can shield a part of the license plate 32. The license plate 32 is arranged such that the display surface on which information is displayed is visible from the rear of the three-wheeled vehicle 1. The shielding portion 50 is movable between a shielding position where a part of the information display on the license plate 32 is shielded and a shielding release position where the shielding of the display is released. The shielding portion 50 covers the display surface from the rear at the shielding position. The first cover 43 constituting the shielding portion 50 moves forward while passing to the right of the license plate 32 in the process of moving from the shielding position to the shielding release position. The second cover 44 constituting the shielding portion 50 moves forward while passing to the left of the license plate 32 in the process of moving from the shielding position to the shielding release position.

[0117] Thereby, while easily avoiding interference of the shielding portion 50 with components (for example, lighting that illuminates the display surface) above or below the license plate 32, switching between shielding and shielding release of the license plate 32 can be realized. Further, since the shielding portion 50 moves clearly between the shielding position and the shielding release position, erroneous operations during mode switching can be effectively prevented.

[0118] The three-wheeled vehicle 1 of the present embodiment includes a mode switching sensor 91 that detects that the shielding portion 50 is in the shielding release position. When the mode switching sensor 91 detects that the shielding portion 50 is in the shielding release position, the controller 23 switches the running mode from the suppression mode to the driving mode. The mode switching sensor 91 is arranged in front, on the side opposite to the display surface on which information is displayed, rather than the license plate 32.

[0119] Thereby, unauthorized access to the mode switching sensor 91 can be prevented.

[0120] The three-wheeled vehicle 1 of this embodiment includes a protective cover 45 that covers the side of the license plate 32 opposite to the display surface. The mode switching sensor 91 is disposed inside the protective cover 45.

[0121] Thereby, unauthorized access to the mode switching sensor 91 can be prevented.

[0122] Although the preferred embodiments of the present disclosure have been described above, the above configuration can be modified as follows, for example. The modifications may be made individually or in any combination of a plurality of modifications.

[0123] The first cover 43 may also be configured to also serve as the first operating member 46, and the second cover 44 may also be configured to also serve as the second operating member 47. In this configuration, the first operating member 46 and the second operating member 47 can be omitted.

[0124] Instead of the configuration in which the first operating member 46 and the second operating member 47 open left and right, the configuration may be changed to open up and down.

[0125] One of the first cover 43 and the second cover 44 may also be omitted. In this configuration, by opening and closing one cover in a single-opening manner, switching between the shielding position and the shielding release position can be realized. The opening and closing of one cover is permitted on the condition that operating forces are simultaneously applied to the first operating member 46 and the second operating member 47.

[0126] In the above embodiment, when the shielding portion 50 is in the shielding position, a part of the license plate 32 is shielded as shown in FIG. 5. Instead of this, the entire license plate 32 may be shielded by the shielding portion 50.

[0127] The convex portions 71 and 72 may also be omitted in the interlocking groove 61. In this case, the forward rotation of only the first link member 41 or only the second link member 42 is blocked only by the frictional force generated between the outer peripheral surface of the connecting rod 60 and the inner wall surface of the interlocking groove 61.

[0128] As the mode switching sensor 91, a non-contact sensor can be used instead of the contact sensor. Examples of the non-contact sensor include an optical sensor such as an infrared sensor, or an inductive sensor that utilizes a magnetic field change.

[0129] The blocking mechanism 67 and the mode switching sensor 91 may be disposed outside the protective cover 45. The protective cover 45 can also be omitted.

[0130] The present disclosure is not limited to the three-wheeled vehicle 1. For example, it can be widely applied to a vehicle whose driving mode is switched according to the presence or absence of the license plate display. Further, the present disclosure can also be applied to, for example, a rowing boat equipped with an electric motor.
