Description

Technical Field

[0001] This application relates to the field of intelligent cockpit technology, and in particular to a footrest assembly and a vehicle. Background Technology

[0002] Footrests are typically located on the driver's side to support the driver's left foot and alleviate fatigue during long drives. They are usually fixed to the vehicle floor by support blocks, creating a fixed tilt angle. However, currently common footrests and support blocks are designed as a single piece, making the position and tilt angle of the pedals unadjustable. This fixed structure is ill-suited to drivers of different heights, leg lengths, shoe types, and driving habits, reducing comfort and ergonomics. Utility Model Content

[0003] In view of this, this application provides a footrest assembly and a vehicle, which allows the tilt angle and position of the footrest to be adjusted.

[0004] One embodiment of this application provides a footrest assembly, including a support member, a footrest, a telescopic assembly, and a translational assembly. The footrest is movably disposed on the support member. The translational assembly is disposed on the support member and rotatably connected to the footrest; the telescopic assembly is disposed on the translational assembly and rotatably connected to the footrest. The telescopic assembly causes the footrest to rotate relative to the support member by telescoping. The translational assembly is configured to cause the telescopic assembly and the footrest to move relative to the support member.

[0005] The footrest's tilt angle can be adjusted by extending and retracting the telescopic component. The position of the footrest can be adjusted by moving the telescopic component and the footrest relative to the support through the translation component. This allows the footrest assembly to adapt to the needs of users with different heights, leg lengths and driving habits, significantly improving driving comfort.

[0006] In at least one embodiment, the translation component includes a first driving member, a sliding member, and a first transmission member. The support member has a guide rail, and the sliding member slides in cooperation with the guide rail. The first driving member is disposed on the support member, and the first driving member drives the first transmission member to move so as to cause the sliding member to slide.

[0007] The first driving component converts the driving force into the linear motion of the sliding component through the first transmission component. The cooperation between the guide rail and the sliding component helps to improve the accuracy of the movement trajectory and reduce the risk of the footrest shifting or wobbling. The translation component, through the coordinated cooperation of the first driving component, the sliding component, and the guide rail, realizes the position adjustment of the footrest relative to the support component.

[0008] In at least one embodiment, the first transmission member includes a first worm wheel and a first worm, the first driving member drives the first worm wheel to rotate, one end of the first worm is engaged with the first worm wheel, and the other end is rotatably connected to the support member; the first worm drives the slider to slide by threading with the slider.

[0009] The first transmission component employs a worm gear drive with threaded engagement to achieve the sliding of the sliding component. Firstly, the first worm gear and the first worm mesh to transmit power. The worm gear drive has a self-locking characteristic, reducing reverse sliding of the sliding component when the drive stops, thus improving positioning stability. Secondly, the threaded engagement converts the rotational motion of the first worm into the linear motion of the sliding component, improving transmission accuracy. Simultaneously, the first worm is supported by both the first worm gear and the support component, enhancing the structural stability of the first transmission component and reducing vibration during transmission.

[0010] In at least one embodiment, the footrest assembly further includes a first rotating connector that connects the sliding member and the footrest, and the footrest and the sliding member are rotatably connected through the first rotating connector.

[0011] When the angle of the footrest is adjusted, the footrest and the sliding member rotate relative to each other through the first rotating connector as the telescopic assembly extends and retracts. The sliding member provides support to the footrest through the first rotating connector, which also guides the rotation direction of the footrest, reducing jamming during rotation and improving the smoothness and accuracy of the footrest's rotation.

[0012] In at least one embodiment, the translation component further includes an extension plate disposed on the support and connected to the slider, the extension plate being slidably connected to the guide rail; a telescopic component is disposed on the extension plate.

[0013] The extension plate provides a stable mounting platform for the telescopic components, enabling the movement of the telescopic components to coordinate with the sliding of the translational components, thereby improving the overall structural rigidity and motion accuracy. Furthermore, the design of the extension plate's slidable connection to the guide rail maintains the freedom of the translational components while reducing localized wear on the guide rail by distributing the load at the sliding connection point between the sliding components and the guide rail, thus extending its service life.

[0014] In at least one embodiment, the telescopic assembly includes a second driving member, a telescopic member, and a second transmission member. The second driving member is disposed on the translation assembly. One end of the telescopic member is connected to the second transmission member, and the other end is rotatably connected to the footrest. The second driving member drives the second transmission member to move, thereby causing the telescopic member to extend or retract.

[0015] The connection and cooperation between the telescopic component, the second transmission component, and the resting plate not only ensures the stability of the telescopic movement, but also allows the resting plate to adaptively adjust its angle during the telescopic component's extension and retraction, reducing jamming. The second drive component drives the telescopic component through the second transmission component, forming a modular transmission structure that facilitates maintenance and adjustment of the extension and retraction stroke.

[0016] In at least one embodiment, the telescopic member includes a sleeve and a push rod, one end of which is rotatably connected to the rest plate; the sleeve has an internal thread, the push rod has an external thread, a portion of the push rod is disposed inside the sleeve, and the push rod can move relative to the sleeve through the engagement of the internal and external threads; the second driving member moves through the second transmission member to drive the push rod to rotate.

[0017] The rotational motion of the push rod is converted into a stable linear telescopic motion through the engagement of the internal thread of the sleeve and the external thread of the push rod, improving the accuracy of telescopic control. The rotatable connection design between the sleeve and the rest plate automatically adapts to angle changes during telescopic movement, reducing motion interference. The engagement of the internal and external threads has a self-locking characteristic, which can reliably lock at any position, ensuring the stability of the telescopic component under load. The second drive component drives the push rod to rotate through the second transmission component, making power transmission direct and efficient, reducing energy loss.

[0018] In at least one embodiment, the second transmission member includes a second worm wheel and a second worm, the second driving member is connected to the second worm and drives the second worm to rotate, the second worm meshes with the second worm wheel, and the second worm wheel is coaxially fixed with the push rod.

[0019] Utilizing the self-locking characteristic of the second worm gear, the relative positions of the push rod and sleeve can be locked immediately when the drive stops, reducing the possibility of load backlash. The coaxial fixed design of the second worm gear and the push rod eliminates intermediate transmission components, reduces motion errors, and improves transmission accuracy. Furthermore, the compact layout of the second worm gear and the second worm gear makes the overall structure more streamlined.

[0020] In at least one embodiment, the footrest assembly further includes a second rotating connector disposed on the translation assembly and connected to the telescopic assembly; the telescopic assembly is rotatably disposed on the translation assembly via the second rotating connector.

[0021] The footrest assembly rotatably connects the telescopic component to the translation component via a second rotating connector, enabling the telescopic component to adaptively adjust its angle during translation or telescoping, reducing motion interference while maintaining stable power transmission.

[0022] In at least one embodiment, the footrest includes a footrest body and a connecting shaft. One end of the telescopic component is provided with a connecting hole, and the connecting shaft passes through the connecting hole. The telescopic component rotates relative to the footrest body through the cooperation between the connecting shaft and the connecting hole.

[0023] The footrest achieves the rotation of the telescopic component relative to the footrest body through the cooperation of the connecting shaft and the connecting hole, allowing the telescopic component to flexibly adjust its angle during movement, avoiding jamming or interference, while maintaining a stable connection and power transmission.

[0024] In at least one embodiment, the footrest assembly further includes a third drive member disposed on the footrest, the third drive member being used to drive the footrest to vibrate.

[0025] When drivers of vehicles or other transportation vehicles are fatigued or inattentive while in motion, the footrest can be vibrated by a third drive component to alert the driver and improve driving safety.

[0026] Embodiments of this application also provide a transportation vehicle including the footrest assembly of any of the above embodiments.

[0027] This vehicle features a footrest assembly that allows for multi-degree-of-freedom adjustment of the footrest. Combined with translation and rotation functions, it enables drivers to flexibly adjust the angle and position of the footrest according to their needs, significantly improving passenger comfort.

[0036] The following detailed description, in conjunction with the accompanying drawings, further illustrates this application. Detailed Implementation

[0037] To make the technical problems, technical solutions, and beneficial effects solved by this application clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0038] Footrests are typically located on the driver's side to support the driver's left foot and alleviate fatigue during long drives. They are usually fixed to the vehicle floor by support blocks, creating a fixed tilt angle. However, currently common footrests and support blocks are designed as a single piece, making the position and tilt angle of the pedals unadjustable. This fixed structure is ill-suited to drivers of different heights, leg lengths, shoe types, and driving habits, reducing comfort and ergonomics.

[0039] One embodiment of this application provides a footrest assembly, including a support member, a footrest, a telescopic assembly, and a translational assembly. The footrest is movably disposed on the support member. The translational assembly is disposed on the support member and rotatably connected to the footrest; the telescopic assembly is rotatably connected to the footrest and is disposed on the translational assembly. The telescopic assembly drives the footrest to rotate relative to the support member by telescoping. The translational assembly is configured to drive the telescopic assembly and the footrest to move relative to the support member.

[0040] The footrest's tilt angle can be adjusted by extending and retracting the telescopic component. The position of the footrest can be adjusted by moving the telescopic component and the footrest relative to the support through the translation component. This allows the footrest assembly to adapt to the needs of users with different heights, leg lengths and driving habits, significantly improving driving comfort.

[0041] The embodiments of this application will be further described below with reference to the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0042] like Figure 1 and Figure 2 As shown, one embodiment of this application provides a footrest assembly 100, which includes a support member 10, a footrest 20, a telescopic component 30, and a translation component 40.

[0043] A footrest 20 is movably mounted on the support 10. A translation component 40 is mounted on the support 10 and rotatably connected to the footrest 20. A telescopic component 30 is mounted on the translation component 40 and rotatably connected to the footrest 20. The telescopic component 30 can extend and retract to rotate the footrest 20 relative to the support 10, thereby adjusting the tilt angle of the footrest 20 relative to the support 10. The translation component 40 is configured to move the telescopic component 30 and the footrest 20 relative to the support 10.

[0044] The tilt angle of the footrest 20 can be adjusted by extending and retracting the telescopic component 30. The telescopic component 40 drives the telescopic component 30 and the footrest 20 to move relative to the support member 10, thereby realizing the position adjustment of the footrest 20. This allows the footrest assembly 100 to adapt to the needs of users with different heights, leg lengths and driving habits, significantly improving driving comfort.

[0045] In some embodiments, such as Figure 1 As shown, when the telescopic component 30 is shortened, the footrest 20 rotates relative to the support member 10 in the first direction R; when the telescopic component 30 is extended, the footrest 20 rotates relative to the support member 10 in the opposite direction of the first direction R; when the translation component 40 is in the adjustment position, the footrest 20 and the telescopic component 30 can move relative to the support member 10 in the second direction X or the opposite direction of the second direction X.

[0046] Please see Figure 1 and Figure 2 In some embodiments, the footrest 20 includes a footrest body 21, which has a first support surface 211 and a second support surface 212 disposed opposite to each other. The first support surface 211 is used to support the driver's feet, and the second support surface 212 is connected to the telescopic component 30, so that the telescopic component 30 is less likely to interfere with the driver's feet when it moves.

[0047] Please see Figure 2 In some embodiments, the footrest 20 further includes a connecting shaft 22, which is disposed on the second support surface 212. One end of the telescopic component 30 is provided with a connecting hole 3211, through which the connecting shaft 22 passes. The telescopic component 30 is rotatably connected to the footrest 20 through the cooperation of the connecting shaft 22 and the connecting hole 3211.

[0048] The footrest 20 achieves the rotation of the telescopic component 30 relative to the footrest body 21 through the cooperation of the connecting shaft 22 and the connecting hole 3211, so that the telescopic component 30 can flexibly adjust the angle during the movement, avoid jamming or interference, and maintain a stable connection and power transmission.

[0049] Please see Figure 2 In some embodiments, the connecting shaft 22 is rotatably connected to the footrest body 21, and the connecting shaft 22 is rotatably disposed in the connecting hole 3211 to achieve a rotatable connection between the telescopic component 30 and the footrest 20. Alternatively, the connecting shaft 22 is fixedly disposed on the footrest body 21, and the connecting shaft 22 is rotatably disposed in the connecting hole 3211 to achieve a rotatable connection between the telescopic component 30 and the footrest 20.

[0050] Please see Figure 1 In some embodiments, the translation component 40 includes a first driving member 41, a sliding member 42, and a first transmission member 43. The support member 10 has a guide rail 11, and the sliding member 42 is slidably engaged with the guide rail 11. The first driving member 41 is disposed on the support member 10, and the first driving member 41 drives the first transmission member 43 to move, thereby causing the sliding member 42 to slide. For example, the sliding member 42 and the guide rail 11 are slidably engaged along a second direction X and in the opposite direction of the second direction X.

[0051] The first driving member 41 converts the driving force into the linear motion of the sliding member 42 through the first transmission member 43. The cooperation between the guide rail 11 and the sliding member 42 helps to improve the accuracy of the movement trajectory and reduce the risk of the footrest 20 deviating or wobbling. The translation component 40 realizes the position adjustment of the footrest 20 relative to the support member 10 through the coordinated cooperation of the first driving member 41, the sliding member 42 and the guide rail 11.

[0052] In some embodiments, the first drive element 41 is a rotary motor.

[0053] Please see Figure 1 , Figure 3 and Figure 4 In some embodiments, the first transmission member 43 includes a first worm gear (not shown) and a first worm 431. The first driving member 41 drives the first worm gear to rotate. One end of the first worm 431 meshes with the first worm gear, and the other end is rotatably connected to the support member 10. The first worm 431 drives the sliding member 42 to slide by threading with the sliding member 42.

[0054] For example, the first worm 431 extends along the second direction X and can rotate about its own axis under the drive of the first drive member 41 and the first worm wheel.

[0055] The first transmission component 43 achieves the sliding of the sliding component 42 through a worm gear drive and threaded engagement. Firstly, the first worm gear and the first worm 431 achieve power transmission through mutual meshing. The worm gear drive has a self-locking characteristic, which reduces the reverse sliding of the sliding component 42 when the drive stops, improving positioning stability. Secondly, the threaded engagement converts the rotational motion of the first worm 431 into the linear motion of the sliding component 42, improving transmission accuracy. Simultaneously, the first worm 431 is doubly supported by the first worm gear and the support component 10, enhancing the structural stability of the first transmission component 43 and reducing vibration generated during transmission.

[0056] Please see Figure 1 and Figure 3 In some embodiments, the support member 10 includes a base 12 and a mounting plate 13. The mounting plate 13 is disposed on the base 12, and the first drive member 41 is disposed on the base 12. The other end of the first worm gear 431 is connected to the base 12.

[0057] In some embodiments, the base 12 is configured as a rectangular frame structure, and the base 12 forms a clearance space 121. The guide rail 11 is disposed on the base 12, and the slider 42 is slidably disposed in the clearance space 121. The first worm gear 431 extends within the clearance space 121, thereby preventing the first worm gear 431 from interfering with other structures and improving the smoothness of the rotation of the first worm gear 431.

[0058] Please see Figure 1 and Figure 3 In some embodiments, two guide rails 11 are provided, and the two guide rails 11 are arranged opposite each other in a third direction Y, which is perpendicular to the second direction X. For example, the third direction Y is the left-right direction of a vehicle or other transportation vehicle.

[0059] The sliding member 42 includes a sliding bracket 421, and the rest plate 20 is rotatably connected to the sliding bracket 421. One end of the sliding bracket 421 is slidably engaged with one of the guide rails 11, and the other end of the sliding bracket 421 is slidably engaged with the other guide rail 11. Both ends of the sliding bracket 421 are supported by the guide rails 11, thereby improving the smoothness of the sliding of the sliding bracket 421.

[0060] In some embodiments, the guide rail 11 includes a first slide groove 111, and the two ends of the sliding bracket 421 are respectively provided with first sliders 4211. Each first slider 4211 is slidably engaged with one of the first slide grooves 111, thereby realizing the sliding connection between the slider 42 and the base 12.

[0061] In some implementations, the guide rail 11 includes a second slider (not shown), and the two ends of the sliding bracket 421 are respectively provided with second slide grooves (not shown). Each second slider slides in cooperation with one of the second slide grooves, thereby realizing the sliding connection between the slider 42 and the base 12.

[0062] Please see Figure 1 and Figure 3 In some embodiments, the slider 42 further includes a nut seat 422, which is connected to the sliding bracket 421. For example, the nut seat 422 is fixed inside the sliding bracket 421. Figure 3 The nut seat 422 marked in the figure indicates the position of the nut seat 422 on the sliding bracket 421. The specific structure of the nut seat 422 is not shown. The nut seat 422 has internal threads (not shown in the figure). The first worm gear 431 passes through the nut seat 422 and is threadedly connected to the nut seat 422, so that when the first worm gear 431 rotates, the sliding member 42 can translate relative to the support member 10.

[0063] Please see Figure 3 In some embodiments, the support member 10 further includes a support base 14 disposed on the base 12. The support base 14 has a mounting hole (not shown), and the other end of the first worm gear 431 is rotatably disposed in the mounting hole. The other end of the first worm gear 431 is connected to the base 12 through the support base 14, so that the base 12 can support the first worm gear 431 and allow the first worm gear 431 to rotate relative to the base 12.

[0064] Please see Figure 4 In some embodiments, the footrest assembly 100 further includes a first rotating connector 50, which connects the sliding member 42 and the footrest 20, and the footrest 20 and the sliding member 42 are rotatably connected through the first rotating connector 50.

[0065] When the angle of the footrest 20 is adjusted, with the extension and retraction of the telescopic assembly 30, the position where the footrest 20 is connected to the sliding member 42 rotates relative to each other through the first rotating connector 50. The sliding member 42 can provide support for the footrest 20 through the first rotating connector 50, and the first rotating connector 50 can guide the rotation of the footrest 20, reducing the problem of jamming during the rotation of the footrest 20 and improving the smoothness and accuracy of the rotation of the footrest 20.

[0066] In some embodiments, the first rotating connector 50 connects the slider 42 and the footrest body 21, and the footrest body 21 and the slider 42 are rotatably connected through the first rotating connector 50.

[0067] In some embodiments, the first rotating connector 50 is a rotating shaft extending along a third direction Y, and the first direction R is the direction about the axis of the first rotating connector 50, so that the footrest 20 can rotate along the first direction R and the opposite direction of the first direction R to achieve adjustment of the tilt angle.

[0068] For example, the first rotating connector 50 passes through the sliding bracket 421 and the resting plate 20, and is rotatably connected to the sliding bracket 421 and the resting plate 20 respectively. Alternatively, the first rotating connector 50 passes through the sliding bracket 421 and the resting plate 20, and is rotatably connected to one of the sliding bracket 421 and the resting plate 20, and is fixedly connected to the other of the sliding bracket 421 and the resting plate 20.

[0069] Please see Figure 1 and Figure 3 In some embodiments, the translation assembly 40 further includes an extension plate 44, which is disposed on the support member 10 and connected to the slider 42. The extension plate 44 is slidably connected to the guide rail 11. For example, the extension plate 44 is slidable relative to the guide rail 11 along a second direction X and the opposite direction of the second direction X. In embodiments where the guide rail 11 includes a first groove 111, the side of the extension plate 44 is inserted into the first groove 111 and is slidable along the first groove 111. A telescopic assembly 30 is disposed on the extension plate 44.

[0070] The extension plate 44 provides a stable mounting platform for the telescopic assembly 30, enabling the movement of the telescopic assembly 30 to coordinate with the sliding of the translation assembly 40, thereby improving the overall structural rigidity and motion accuracy. Furthermore, the design of the extension plate 44 being slidably connected to the guide rail 11 maintains the degree of freedom of the translation assembly 40 while reducing localized wear on the guide rail 11 by distributing the load at the sliding connection point between the sliding member 42 and the guide rail 11, thus extending its service life.

[0071] In some embodiments, a sliding wheel (not shown) is provided below the extension plate 44 to support the extension plate 44, so that the extension plate 44 can slide smoothly.

[0072] Please see Figure 1 and Figure 2 In some embodiments, the telescopic assembly 30 includes a second driving member 31, a telescopic member 32, and a second transmission member 33. The second driving member 31 is disposed on the translation assembly 40. One end of the telescopic member 32 is connected to the second transmission member 33, and the other end is rotatably connected to the footrest 20. The second driving member 31 drives the second transmission member 33 to move, thereby causing the telescopic member 32 to extend or retract.

[0073] The connection and cooperation between the telescopic component 32, the second transmission component 33, and the resting plate 20 not only ensures the stability of the telescopic movement, but also allows the resting plate 20 to adaptively adjust its angle during the telescopic component 32's extension and retraction, reducing jamming. The second drive component 31 drives the telescopic component 32 to move through the second transmission component 33, forming a modular transmission structure that facilitates maintenance and adjustment of the extension and retraction stroke.

[0074] Please see Figure 1 and Figure 2 In some embodiments, the telescopic member 32 includes a sleeve 321 and a push rod 322, one end of which is rotatably connected to the footrest 20. The sleeve 321 has an internal thread (not shown), and the push rod 322 has an external thread (not shown). A portion of the push rod 322 is disposed within the sleeve 321, and the push rod 322 can move relative to the sleeve 321 through the engagement of the internal and external threads. The relative movement direction between the push rod 322 and the sleeve 321 is the telescopic direction of the telescopic member 32. The second driving member 31 moves through the second transmission member 33 to drive the push rod 322 to rotate.

[0075] The rotational motion of the push rod 322 is converted into a stable linear telescopic motion through the engagement of the internal thread of the sleeve 321 and the external thread of the push rod 322, improving the accuracy of telescopic control. The rotatable connection design between the sleeve 321 and the rest plate 20 automatically adapts to angle changes during telescopic movement, reducing motion interference. The engagement of the internal and external threads has a self-locking characteristic, which can reliably lock at any position, ensuring the stability of the telescopic component 32 under load. The second drive component 31 drives the push rod 322 to rotate through the second transmission component 33, making the power transmission direct and efficient, reducing energy loss.

[0076] Please see Figure 2 In some embodiments, the sleeve 321 has a connecting hole 3211, through which the sleeve 321 is rotatably connected to the connecting shaft 22.

[0077] In some embodiments, the second drive element 31 is a rotary motor.

[0078] Please see Figure 5 In some embodiments, the second transmission member 33 includes a second worm 331 and a second worm wheel 332. The second driving member 31 is connected to the second worm 331 and drives the second worm 331 to rotate. The second worm 331 meshes with the second worm wheel 332, and the second worm wheel 332 is coaxially fixed with the push rod 322.

[0079] Utilizing the self-locking characteristic of the second worm gear 331, the relative positions of the push rod 322 and the sleeve 321 can be locked immediately when the drive stops, reducing the possibility of load backlash. The coaxial fixed design of the second worm gear 332 and the push rod 322 eliminates intermediate transmission components, reduces motion errors, and improves transmission accuracy. The compact layout of the second worm gear 332 and the second worm gear 331 makes the overall structure more streamlined.

[0080] Please see Figure 4 In some embodiments, the footrest assembly 100 further includes a second rotating connector 60, which is disposed on the translation assembly 40 and connected to the telescopic assembly 30. The telescopic assembly 30 is rotatably disposed on the translation assembly 40 via the second rotating connector 60.

[0081] The footrest assembly 100 rotatably connects the telescopic component 30 to the translation component 40 via the second rotating connector 60, enabling the telescopic component 30 to adaptively adjust its angle during translation or telescopic movement, reducing motion interference while maintaining stable power transmission.

[0082] In some embodiments, the second rotating connector 60 is a rotating shaft extending along a third direction Y, and the first direction R is the direction about the axis of the second rotating connector 60, so that the telescopic component 30 can rotate along the first direction R and the opposite direction of the first direction R, thereby realizing the adaptive adjustment of the angle between the telescopic component 30 and the translation component 40 during the telescopic process.

[0083] For example, the second rotating connector 60 is connected to the second driving member 31 and the extension plate 44, and is rotatably connected to both the second driving member 31 and the extension plate 44. Alternatively, the second rotating connector 60 is connected to the second driving member 31 and the extension plate 44, and is rotatably connected to one of the second driving member 31 and the extension plate 44, and fixedly connected to the other of the second driving member 31 and the extension plate 44.

[0084] Please see Figure 2 and Figure 3 In some embodiments, the footrest assembly 100 further includes a third drive member 70 disposed on the footrest 20, the third drive member 70 being used to drive the footrest 20 to vibrate. For example, the third drive member 70 is a vibration motor or an electromagnetic vibrator.

[0085] When a driver is fatigued or inattentive while driving a vehicle or other transportation vehicle, the third drive component 70 can drive the footrest 20 to vibrate, thereby reminding the driver and improving driving safety.

[0086] In some embodiments, the third drive member 70 is disposed on the second support surface 212.

[0087] Please seeFigure 6 An embodiment of this application also provides a transportation vehicle 200, including the rest board assembly 100 in any of the above embodiments.

[0088] The vehicle 200, by setting up a footrest assembly 100, realizes multi-degree-of-freedom adjustment of the footrest 20. Combined with translation and rotation functions, it enables the driver to flexibly adjust the angle and position of the footrest 20 according to needs, significantly improving riding comfort.

[0089] In some embodiments, the footrest assembly 100 can be applied in various vehicles driven and ridden by passengers to support the driver's left foot or the feet of other passengers, relieving foot fatigue over long periods. The vehicle 200, such as a car, has the footrest assembly 100 installed in the driver's cabin, with the support member 10 mounted on the floor of the driver's cabin. The footrest 20 changes its distance from the driver's seat by moving in the fore-and-aft direction of the vehicle to accommodate different driver leg lengths. The vehicle 200 can also be a flying car, train, etc.

[0090] In some embodiments, the vehicle 200 further includes a control system (not shown) connected to the first drive member 41, the second drive member 31 and the third drive member 70, and the control system is capable of sending signals to the footrest assembly 100 to control the operation of the first drive member 41, the second drive member 31 and the third drive member 70.

[0091] In some embodiments, the vehicle 200 further includes a brake pedal (not shown) and an accelerator pedal (not shown), and the footrest assembly 100 is arranged side by side with the brake pedal and the accelerator pedal in the left-right direction of the vehicle 200. Compared to the brake pedal and the accelerator pedal, the footrest 20 is located on the far left of the driver, thereby facilitating the placement of the driver's left foot.
