Electric car ramp

Abstract

The application discloses an electric car ramp, which comprises a driving mechanism and a foot support mechanism. The driving mechanism comprises a driving piece, a first transmission piece, a second transmission piece and a movable piece. The driving piece is in transmission connection with the first transmission piece. The movable piece is movably arranged between the first transmission piece and the second transmission piece. The first transmission piece is in transmission connection with the second transmission piece in the first direction through the movable piece. The second transmission piece is fixedly connected with the foot support mechanism. The driving piece drives the first transmission piece to reciprocate in the first direction, and drives the second transmission piece to move through the transmission connection between the first transmission piece and the second transmission piece through the movable piece. When the foot support mechanism is subjected to a force for switching from the supporting position to the storage position, the second transmission piece is locked in the first direction through the movable piece. Thus, the electric car ramp can automatically switch between the supporting position and the storage position, and can avoid the damage of the electric car body after the position switching caused by the external force.

Description

Technical Field

[0001] This application relates to the field of electric bicycle accessories, and in particular to an electric bicycle ladder. Background Technology

[0002] Electric vehicle ladders are crucial support components for electric vehicles, ensuring stability when parked. In some technologies, users can switch the ladder between an extended (supporting the vehicle) and a retracted (folded up when in motion) position by stepping on it or manually operating it. While convenient, this design presents significant safety hazards. When a vehicle is parked, if the ladder is subjected to unexpected external forces (such as a collision, scraping, or road bumps), it may unexpectedly switch from the extended to the retracted position, causing the vehicle to lose support and tip over. This could damage the vehicle and pose a risk to personal safety. Such accidental tipping incidents due to external interference are particularly common in public places or densely populated areas, affecting the stability and reliability of electric vehicle use.

[0004] In view of the above problems, this utility model proposes an electric vehicle ladder, which aims to solve the technical problem that the electric vehicle ladder is easily affected by external forces and may accidentally switch between the supported position and the stored position.

The driving member drives the first transmission member to reciprocate along the first direction, so that when the first transmission member is connected to the second transmission member through the movable member, it drives the second transmission member to reciprocate in the first direction, so that the foot support mechanism switches between the supported position and the retracted position. When the foot support mechanism is subjected to a force that causes it to switch from the supported position to the retracted position, the second transmission member is locked in the first direction via the movable member.

[0006] Furthermore, the driving member drives the first transmission member to reciprocate along a first direction, so that when the first transmission member is connected to the second transmission member through the movable member, it drives the second transmission member to reciprocate along the first direction.

[0007] Furthermore, an active space extending along the first direction is provided between the first transmission member and the second transmission member; the active space includes two abutment surfaces arranged opposite each other in the second direction, the second direction being perpendicular to the first direction and the rotation axis direction of the first transmission member; The driving component drives the first transmission component to move the movable component within the activity space to the transmission connection with the second transmission component, and the second transmission component drives the foot support mechanism to switch between the supported position and the retracted position; When the foot support mechanism is subjected to a force that causes it to switch from the supported position to the retracted position, the movable member locks between the two stop surfaces.

[0008] Furthermore, the drive member also includes an elastic member disposed between the movable member and the second transmission member; the movable member is elastically locked between the two stop surfaces by the elastic member, so that the movable member remains locked when the foot support mechanism is subjected to a force that switches it from the supported position to the retracted position.

[0009] Furthermore, the electric elevator also includes a limiting ring disposed between the first transmission member and the second transmission member. The limiting ring surrounds the periphery of the second transmission member, and the inner circumferential surfaces of the first transmission member, the second transmission member, and the limiting ring enclose the active space. The inner circumferential surface of the limiting ring is one of the stop surfaces, and both the inner circumferential surface of the limiting ring and the outer circumferential surface of the movable part are arc surfaces.

[0010] In one embodiment, the active space further includes a first transmission surface disposed on the first transmission member and a second transmission surface disposed on the second transmission member; the first transmission surface and the second transmission surface are disposed opposite to each other in the first direction; the first transmission surface, the second transmission surface and the two stop surfaces together enclose the active space; The first transmission member pushes the movable member toward the second transmission surface through the first transmission surface, and the movable member pushes the second transmission member to reciprocate in the first direction through the second transmission surface, so that the foot support mechanism switches between the supported position and the retracted position.

[0011] Furthermore, the driving mechanism includes multiple movable components and multiple movable spaces spaced apart along the first direction; the multiple movable components are respectively disposed in the multiple movable spaces; The first transmission component includes a first transmission part, which has two first transmission surfaces arranged opposite to each other along the first direction; the first transmission part is provided with the movable component on both sides of the first direction.

[0012] Furthermore, the first transmission component includes a transmission disk and at least two first transmission portions protruding from the side of the transmission disk; The second transmission member includes a plurality of second transmission parts and a plurality of locking parts; the transmission parts and the locking parts are alternately arranged at intervals in the first direction; the second transmission part has two second transmission surfaces arranged opposite to each other in the first direction, and the locking part has two stop surfaces arranged opposite to each other in the first direction; The drive mechanism further includes a housing and a limiting ring disposed between the housing and the first transmission member. The limiting ring surrounds the periphery of the second transmission member. The first transmission part is disposed between the limiting ring and the locking part. The first transmission part, the locking part, the second transmission part, and the transmission disk enclose the active space.

[0013] Furthermore, the electric elevator also includes a trigger and a sensor; the transmission disc is provided with a transmission rod, the axis of which is parallel to the axis of the transmission disc; the trigger and the transmission disc are engaged in a limit engagement on the axis of the transmission disc. The trigger can rotate along the first direction, with one end of the trigger located on the movement trajectory of the transmission rod, and the sensing element located on the movement trajectory of the other end of the trigger.

[0014] In one embodiment, the foot support mechanism includes a body and a first connecting member; the electric elevator further includes a drive shaft and a second connecting member; The drive component is placed inside the housing, and the transmission shaft passes through the first transmission component and the second transmission component; The first connector is engaged with the drive shaft in the first direction, and the first connector is provided with a limiting hole; the body is provided with a limiting tongue inserted into the limiting hole, the limiting tongue and the limiting hole are engaged in the first direction, and the limiting tongue and the limiting hole are engaged in the second direction; the second connector is fixedly connected to the housing of the electric elevator and rotatably connected to the body.

[0015] This utility model of an electric vehicle ladder utilizes the power transmission mechanism of its movable components to form a power transmission chain consisting of a driving component, a first transmission component, a movable component, and a second transmission component. This allows the foot support mechanism to switch between the extended and retracted positions. Simultaneously, when the foot support mechanism is subjected to a force that causes it to switch from the extended to the retracted position, the power blocking effect of the movable component locks the second transmission component in the first direction, preventing the foot support mechanism from changing its original position. Therefore, when the electric vehicle is parked in the extended position, even if the foot support mechanism is subjected to external forces (such as collisions, scrapes, or road vibrations), the locking design of the movable component prevents the second transmission component from transmitting force to the first transmission component (driving component), thus maintaining the foot support mechanism's position and preventing the vehicle from suddenly tipping over, thereby improving the safety of personnel and the vehicle.

[0023] This utility model proposes an electric elevator.

[0024] In this embodiment of the utility model, please refer to Figures 1 to 10 The electric elevator 100 includes a drive mechanism 10 and a foot support mechanism 20; The drive mechanism 10 includes a drive member 11, a first transmission member 12, a second transmission member 13, and a movable member 14; the drive member 11 is driveably connected to the first transmission member 12; the movable member 14 is movably disposed between the first transmission member 12 and the second transmission member 13, and the first transmission member 12 is reciprocally driveably connected to the second transmission member 13 in a first direction through the movable member 14; the second transmission member 13 is fixedly connected to the foot support mechanism 20. The driving member 11 drives the first transmission member 12 to reciprocate along the first direction, so that when the first transmission member 12 is connected to the second transmission member 13 through the movable member, it drives the second transmission member 12 to reciprocate in the first direction, so that the foot support mechanism 20 switches between the supported position and the retracted position. When the foot support mechanism 20 is subjected to a force that causes it to switch from the supported position to the retracted position, the second transmission member 13 is locked in the first direction by the movable member 14.

[0025] In this embodiment, the main function of the drive mechanism 10 is to provide power and transmit the power to the foot support mechanism 20 through the transmission component, so that the foot support mechanism 20 can switch between the extended position (the ladder extends to support the vehicle) and the retracted position (the ladder retracts without affecting the vehicle's movement). The drive mechanism 10 includes a drive component 11, a first transmission component 12 and a second transmission component 13, and a movable component 14.

[0026] The drive component 11 serves as the power source, and can be a motor or hydraulic actuator, etc. Its function is to output power to move the electric ladder, switching it between the extended and retracted positions. The first transmission component 12 connects to the drive component 11, and plays the role of transmitting and changing the direction of motion; it is usually a gear, crank, or connecting rod mechanism. The transmission connection between the drive component 11 and the first transmission component 12 can be gear meshing or a connecting rod structure, which is not limited here.

[0027] The second transmission component 13 is fixedly connected to the foot support mechanism 20. It receives transmission from the first transmission component 12 (via the movable component 14), specifically enabling the switching of the position of the foot support mechanism 20. The second transmission component 13 can be a rotating shaft, gear, rack, or rocker arm. The fixed connection between the second transmission component 13 and the foot support mechanism 20 allows for synchronous movement of the second transmission component 13 and the foot support mechanism 20. This fixed connection can be achieved through a pin, bolt connection, etc.

[0028] The movable component 14 serves as a medium for power transmission, capable of both power transmission and locking. Specifically, when the driving component 11 drives the first transmission component 12, the movable component 14 will shift accordingly, transmitting power to the second transmission component 13. The second transmission component 13 then moves, thereby causing the foot support mechanism 20 to unfold or retract. When the foot support mechanism 20 transmits external force to the second transmission component 13, the presence of the movable component 14 causes the second transmission component 13 to lock in the first direction, preventing the foot support mechanism 20 from switching from the unfolded position to the retracted position due to external force. The movable component 14 can be a slider, cam, or pin, etc., and is not limited here.

[0029] The first direction can be the rotation direction of the foot support mechanism 20, or it can be a straight line direction; it is not limited here.

[0030] In the first scheme where the direction is linear, when the first transmission member 12 (e.g., a drive rack) of the driving member 11 moves in a specific direction, it drives the movable member 14 (e.g., a lever) to insert along the linear direction and engage with the ratchet of the second transmission member 13 (e.g., a transmission gear), achieving rigid transmission and driving the foot support to switch positions. When the foot support mechanism 20 is subjected to an external force that causes it to retract, the second transmission member 13 attempts to reverse. Because its ratchet and the ratchet of the movable member 14 are designed for a one-way locking engagement, the second transmission member 13 generates a linear counter-force acting on the movable member 14. At this time, the movable member 14 is rigidly locked in the linear position by the first transmission member 12 (e.g., a rack) or its guide rail, and cannot be pushed, thereby preventing the second transmission member 13 from reversing and achieving locking.

[0031] In some embodiments, the first direction is the rotation direction of the foot support mechanism 20, and the first transmission member 12 is reciprocally connected to the second transmission member 13 in the first direction via the movable member 14. The electric elevator 100 also includes a transmission shaft 60 passing through the first transmission member 12 and the second transmission member 13. The transmission shaft 60 includes a cylindrical section and a prism section connected to each other. The cylindrical end is rotatably connected to the first transmission member 12, and the prism section is upper-limited connected to the first transmission member 13 and the foot support mechanism 20 in the rotation direction.

[0032] This utility model's electric vehicle ladder 100, through the power transmission action of the movable component 14, forms a power transmission chain of "drive component 11, first transmission component 12, movable component 14, and second transmission component 13," allowing the foot support mechanism 20 to switch between the extended and retracted positions. Simultaneously, when the foot support mechanism 20 is subjected to a force that causes it to switch from the extended to the retracted position, the power blocking action of the movable component 14 locks the second transmission component 13 in the first direction, preventing the foot support mechanism 20 from changing its original position. Thus, when the electric vehicle is parked in the extended position, even if the foot support mechanism 20 is subjected to external forces (such as collisions, scrapes, or road vibrations), due to the locking design of the movable component 14, the second transmission component 13 will be unable to transmit force to the first transmission component 12 (drive component 11), thereby maintaining the position of the foot support mechanism 20, preventing the entire vehicle from suddenly tipping over, and improving the safety of personnel and the vehicle.

[0033] Furthermore, the driving member 11 drives the first transmission member 12 to reciprocate along the first direction, so that when the first transmission member 12 is connected to the second transmission member 13 through the movable member 14, it drives the second transmission member 13 to reciprocate along the first direction.

[0034] Unlike the first transmission component 12 which uses linear reciprocating or unidirectional rotary transmission, in this embodiment, the first transmission component 12 is connected to the second transmission component 13 by reciprocating rotation along the first direction. This allows the first transmission component 12 to be directly coaxial with the drive component 11 or to engage with a simple gear, thus driving the foot support mechanism 20 in both forward and reverse stroke directions. This eliminates the need for a linear-to-rotation conversion mechanism or a unidirectional clutch mechanism, reducing the number of intermediate transmission links and friction pairs, resulting in a more compact structure. At the same time, when the vehicle is subjected to unexpected external forces, the reciprocating rotary connection provides a certain degree of obstruction due to the limited rotation angle. This, combined with a locking mechanism, can prevent accidental storage, thereby improving the safety and reliability of the entire vehicle when parked.

[0035] Furthermore, an active space 15 extending along a first direction is provided between the first transmission member 12 and the second transmission member 13; the active space 15 includes two abutment surfaces 151 arranged opposite each other in a second direction, the second direction being perpendicular to the first direction and the rotation axis direction of the first transmission member. The driving component 11 drives the first transmission component 12 to push the movable component 14 to move within the activity space 15 to the transmission connection to the second transmission component 13. The second transmission component 13 drives the foot support mechanism 20 to switch between the supported position and the folded position. When the foot support mechanism 20 is subjected to a force that causes it to switch from the supported position to the retracted position, the movable member 14 is locked between the two stop surfaces 151.

[0036] In this embodiment, the movement of the movable member 14 within the movable space 15 physically separates the transmission and locking functions, ensuring smooth transmission and rigidity during locking. Specifically, the movable space 15 provides an orderly and defined movement path for the movable member 14, allowing it to move in a predetermined direction (the first direction) while preventing disorderly swaying. Furthermore, the change in the movable space 15 provides a locking position for the movable member 14, so that when an external force is applied to the foot support mechanism 20, the movable space 15 and the movable member 14 cooperate to lock the second transmission member 13 in the first direction, thereby preventing the foot support mechanism 20 from rotating. The specific shape of the movable space 15 is not limited here. It is understood that the size and position of the movable space 15 are constantly changing during the movement of the movable member 14.

[0037] Specifically, in the active space 15, the stop surface 151, which is arranged opposite to the movable member 14 in the second direction, cooperates with the movable member 14 to lock the movable member 14, thereby blocking the power transmission of the movable member 14 and preventing the second transmission member 13 from driving the foot support mechanism 20 to rotate. The shape of the stop surface 151 can be flat or curved, and is not limited here.

[0038] Furthermore, the drive member 11 also includes an elastic member 16 disposed between the movable member 14 and the second transmission member 13; the movable member is elastically locked between the two stop surfaces 151 by the elastic member 16, so that the movable member 14 remains locked when the foot support mechanism 20 is subjected to a force that switches it from the supported position to the retracted position.

[0039] In this embodiment, the elastic element 16 can be a spring, an elastic washer, or other structure with elastic recovery function. When an external force causes the foot support mechanism 20 to attempt to switch from the supported position to the retracted position, the elastic force generated by the elastic element 16 presses the movable element 14 toward the locking position, so that the stop surface 151 of the movable element 14 stably abuts against the surface of the corresponding movable element 14, forming a mechanical lock.

[0040] Understandably, regardless of its position, the resilient element 16 always tends to press the movable element 14 towards the locked position. Considering the minute wear gaps that may develop between components during mechanical use, the resilient element 16 provides a continuous clamping force that automatically compensates for gaps caused by wear or installation tolerances, ensuring the locking mechanism maintains reliable engagement over a long period and extending product lifespan.

[0041] In some embodiments, the second transmission member 13 is provided with a mounting groove, and part of the elastic member 16 is placed in the mounting groove. In this way, the positioning accuracy between the elastic member 16 and the second transmission member 13 is improved, and problems such as deviation or tilting of the elastic member 16 during operation are avoided, which could cause unstable or interrupted power transmission.

[0042] Furthermore, the electric elevator 100 also includes a limiting ring 30 disposed between the first transmission member 12 and the second transmission member 13. The limiting ring 30 surrounds the periphery of the second transmission member 13, and the inner circumferential surfaces of the first transmission member 12, the second transmission member 13, and the limiting ring 30 enclose an active space 15. The inner circumferential surface of the limiting ring 30 is one of the stop surfaces 151, and both the inner circumferential surface of the limiting ring 30 and the outer circumferential surface of the movable member 14 are arc surfaces.

[0043] In this embodiment, the limiting ring 30, in cooperation with the first and second transmission members 13, encloses the range of motion of the movable member 14, i.e., the activity space 15. The inner circumferential surface of the limiting ring 30 and the outer circumferential surface of the movable member 14 form continuous contact through surface contact, improving guiding accuracy. At the same time, the cooperation between the arc surfaces can reduce frictional resistance and prevent jamming during the movement of the movable member 14. Compared with planes or angular surfaces, arc surfaces are better able to cope with slight eccentricity and have strong fault tolerance.

[0044] In one embodiment, the active space 15 includes a first transmission surface 121 disposed on the first transmission member 12 and a second transmission surface 131 disposed on the second transmission member 13; the first transmission surface 121 and the second transmission surface 131 are disposed opposite to each other in a first direction; the first transmission surface 121, the second transmission surface 131 and the two stop surfaces 151 together enclose the active space 15. The first transmission member 12 pushes the movable member 14 toward the second transmission surface 131 via the first transmission surface 121. The movable member 14 pushes the second transmission member 13 to reciprocate in the first direction via the second transmission surface 131, so that the foot support mechanism 20 switches between the supported position and the retracted position.

[0045] In this embodiment, since the first transmission surface 121 and the second transmission surface 131 are arranged opposite to each other in the first direction, the movable part 14 moves along a controlled trajectory between the two transmission surfaces, which effectively reduces the transmission loss and movement deviation caused by component offset, vibration or external force interference.

[0046] Furthermore, the drive mechanism 10 includes a plurality of movable parts 14 and a plurality of movable spaces 15 spaced apart along a first direction; the plurality of movable parts 14 are arranged one-to-one within the plurality of movable spaces 15; the first transmission member 12 includes a first transmission part 122, the first transmission part 122 having two first transmission surfaces 121 arranged opposite to each other along the first direction; the first transmission part 122 is provided with movable parts 14 on both sides in the first direction.

[0047] In this embodiment, multiple activity spaces 15 can distribute stress and wear, extending the overall lifespan of the structure.

[0048] When the driving member 11 drives the first transmission part 122 to move forward in the first direction, the first transmission surface 121 facing the forward side contacts and pushes the movable part 14 in the movable space 15 on that side in turn, so that the movable part 14 is displaced in the corresponding movable space 15, and further transmits the power to the second transmission member 13 through the movable part 14 to realize the action of the foot support mechanism 20 (e.g., switching from storage to support).

[0049] When the driving member 11 drives the first transmission part 122 to move in the opposite direction along the first direction, the first transmission surface 121 facing the opposite side contacts the movable part 14 of the movable space 15 on that side in sequence, pushing it to move in the opposite direction, thereby transmitting the force to the second transmission member 13, causing the foot support mechanism 20 to move in the opposite direction (e.g., switching from supporting to storing). It is worth noting that the forward and reverse directions mentioned above are only set for the convenience of description, and can be adjusted according to the specific structure and requirements in actual applications.

[0050] Furthermore, the first transmission member 12 includes a transmission disk 123 and at least two first transmission portions 122 protruding from the side of the transmission disk 123; The second transmission member 13 includes a plurality of second transmission parts 132 and a plurality of locking parts 133; the transmission parts and locking parts 133 are alternately arranged at intervals in a first direction; the second transmission part 132 has two second transmission surfaces 131 arranged opposite to each other in the first direction, and the locking part 133 has two stop surfaces 151 arranged opposite to each other in the first direction. The drive mechanism 10 also includes a housing 80 and a limiting ring 30 disposed between the housing 80 and the first transmission member 12. The limiting ring 30 surrounds the periphery of the second transmission member 13. The first transmission part 122 is disposed between the limiting ring 30 and the locking part 133. The first transmission part 122, the locking part 133, the second transmission part 132, and the transmission disk 123 enclose and form an active space 15.

[0051] In this embodiment, the first direction is the direction in which the first transmission member 12 reciprocates relative to the second transmission member 13, and may also be the direction in which the locking action occurs. The second transmission part 132 has two second transmission surfaces 131 arranged opposite each other in the first direction, meaning that the second transmission part 132 has two mutually opposing contact surfaces in this direction, corresponding to two possible force directions (forward / reverse). The locking part 133 has two stop surfaces 151 arranged opposite each other in the first direction. The two stop surfaces 151 respectively cooperate with the inner circumferential surface of the corresponding limiting ring 30, forming a mechanical lock with the moving member 14, preventing the foot support mechanism 20 from rotating under external force.

[0052] When the movement of the second transmission unit 132 in the first direction is subjected to an unexpected external force (whether from the forward or reverse direction), it may be pushed away from its normal position. If the locking part 133 only has a single-sided stop, it can only block unexpected external forces in one direction.

[0053] Furthermore, the electric elevator 100 also includes a trigger 40 and a sensor 50; a transmission rod 124 is provided on the transmission disk 123, and the axial direction of the transmission rod 124 is parallel to the axial direction of the transmission disk 123; the trigger 40 and the transmission disk 123 are in upper limit engagement in the axial direction of the transmission disk 123; the trigger 40 can rotate in a first direction, one end of the trigger 40 is located on the movement trajectory of the transmission rod 124, and the sensor 50 is located on the movement trajectory of the other end of the trigger 40.

[0054] In this embodiment, the trigger 40 converts the mechanical movement of the transmission rod 124 into a triggering action at the other end, thereby enabling physical or non-contact interaction with the sensing element 50 (sensor) to achieve detection or status signal feedback. The trigger 40 can be a plate-shaped paddle or a spring, etc.

[0055] The sensor 50 detects whether the trigger 40 has reached the predetermined position, thereby determining the operating state of the electric elevator 100 (e.g., fully extended, fully retracted, or in an intermediate state), and providing a signal for the control circuit or safety protection. The sensor 50 can be a limit switch, a mechanical limit switch, a photoelectric sensor, a Hall sensor, etc., and is not limited here.

[0056] The axis of the transmission rod 124 is parallel to the axis of the transmission disc 123, meaning that the transmission rod 124 moves synchronously with the transmission disc 123, and can accurately reflect the operating status of the transmission disc 123. The transmission rod 124 can be a cylindrical pin, a bent rod (with an adjustable trigger angle), etc.

[0057] The trigger 40 is engaged with the transmission disk 123 at the upper limit of the axial direction of the transmission disk 123, so that the trigger 40 will not slide along the axial direction, reducing positional deviation. At the same time, the trigger 40 can rotate around the first direction, so that it can undergo controlled displacement when pushed by the transmission rod 124.

[0058] Specifically, after the transmission disc 123 rotates, the transmission rod 124 enters the trigger position and pushes the trigger element 40 to rotate. Then, the other end of the trigger element 40 enters the sensing area, and the sensing element 50 outputs a signal. This indirect triggering method has a simple structure and can add a state detection function without changing the original transmission path, which is beneficial to achieving multiple functions while maintaining a compact overall structure.

[0059] In some embodiments, a mounting boss is provided on the inner wall surface of the housing 80, the trigger 40 is sleeved on the mounting boss, and the drive shaft 60 passing through the drive disk 123 is inserted into the mounting boss; at the same time, a flange is provided on the drive disk 123, which abuts against the trigger 40 so that the trigger 40 and the drive disk 123 are in upper axial positioning engagement.

[0060] In one embodiment, the foot support mechanism 20 includes a body 21 and a first connecting member 22; the electric elevator 100 also includes a drive shaft 60 and a second connecting member 23; the drive member 11 is placed inside the housing 80, and the drive shaft 60 passes through the first drive member 12 and the second drive member 13; the first connecting member 22 is in upper limit engagement with the drive shaft 60 in a first direction, and the first connecting member 22 is provided with a limiting hole 221; the body 21 is provided with a limiting tongue 211 inserted into the limiting hole 221, the limiting tongue 211 and the limiting hole 221 are in upper limit engagement in the first direction, and the limiting tongue 211 and the limiting hole 221 are in movable engagement in the second direction of the drive shaft 60; the second connecting member 23 is fixedly connected to the housing 80 of the electric elevator 100 and rotatably connected to the body 21.

[0061] In this embodiment, the main body 21 is the main load-bearing and support part of the foot support structure, which can directly contact the ground to provide stable support for the vehicle.

[0062] The first connector 22 cooperates with the body 21 to make a limiting connection with the drive shaft 60, thereby realizing the position limitation and force transmission or restriction between the drive shaft 60.

[0063] The drive shaft 60 passes between the first drive member 12 and the second drive member 13, and is equivalent to an intermediate shaft for power transmission.

[0064] A limiting hole 221 is formed on the first connecting member 22, and a limiting tongue 211 is disposed on the body 21, which can be inserted into the limiting hole 221. The limiting hole 221 and the limiting tongue 211 engage in a limiting fit in the first direction, so that after the first connecting member 22 receives the transmission from the drive shaft 60, it can drive the body 21 to move synchronously through the engagement of the limiting hole 221 and the limiting tongue 211. In other words, in this embodiment, the engagement of the limiting hole 221 and the limiting tongue 211 enables the drive shaft 60 to drive the foot support mechanism 22 to move.

[0065] The second connector 23 is fixedly connected to the housing 80 of the electric vehicle ladder 100 and is rotatably connected to the body 21 of the foot support mechanism 20.

[0066] In related technologies, the drive shaft 60 is directly inserted into the foot support mechanism 20, meaning the foot support mechanism 20 is directly rotatably connected to the drive shaft 60. As the foot support mechanism 20 is used more frequently, the drive shaft 60 connected to the foot support mechanism 20 may become loose to some extent, leading to instability in the foot support mechanism 20 during position switching.

[0067] In this embodiment, the cooperation between the limiting hole 221 and the limiting tongue 211 allows the foot support structure to rotate stably in the first direction. Simultaneously, due to the gap between the limiting hole 221 and the limiting tongue 211 in the second direction, the limiting member and the limiting tongue 211 can maintain a movable engagement in the second direction, thus allowing the foot support mechanism 20 to have a certain degree of freedom in the second direction. It can be understood that even if the pivot shaft 94, which is rotatably connected to the body 21 of the foot support mechanism 20, becomes loose, this embodiment compensates for the deviation caused by the loosening of the pivot shaft 94 by maintaining a movable engagement between the limiting hole 221 and the limiting tongue 211 in the second direction. This effectively reduces the swaying amplitude of the foot support mechanism caused by the loosening of the pivot shaft 94, thereby effectively avoiding instability of the foot support mechanism caused by the loosening of the pivot shaft 94 (i.e., the drive shaft in related technologies).

[0068] In some embodiments, the electric vehicle ladder 100 further includes a first housing 80, a second housing 80, a motor, a buzzer 91, a circuit board, a waterproof and breathable membrane 92, and a gear set. The first housing 80 and the second housing 80 are aligned and joined together. The circuit board, gear set 17, trigger 40, and sensor 50 are all housed within the first housing 80. The motor, buzzer 91, transmission mechanism, and part of the drive mechanism 10 (first transmission component 12, second transmission component 13, etc.) are all housed within the second housing 80. The second housing 80 has an assembly groove, within which the waterproof and breathable membrane 92 is installed and exposed. The second housing 80 also has a cable passage hole 93 adjacent to the mounting groove, through which the electric vehicle connection cable passes.

[0069] Understandably, in some embodiments, due to the large size of the motor, a portion of the second housing 80 is raised to accommodate the motor. Therefore, other areas of the second housing 80, together with the second connector 23, form an accommodating space for the installation of part of the drive mechanism 10 and the foot support mechanism 20. This allows for a more compact overall structure of the electric elevator 100.

[0070] In some embodiments, the second connector 23 is provided with a mounting portion for connecting to an electric vehicle. The mounting portion can be any shape, such as plate or strip.
