Description

Technical Field

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

[0002] As the automotive industry continues to develop, users have increasingly higher demands for vehicle comfort. Vehicles are no longer just a means of transportation; they have become important spaces for people to travel and rest. To improve user comfort, more and more cars are being equipped with zero-gravity seats, allowing users to rest in an optimal reclining position. Currently, most zero-gravity seats on the market, due to space constraints, generally only have short leg rests. These short footrests only support the user's lower legs and cannot effectively support the user's heels. Although some vehicles have footrest structures that support the user's feet, these structures are generally directly mounted on the horizontal floor in front of the seat, severely encroaching on the space beneath the horizontal floor or causing the entire horizontal floor to be raised. Furthermore, the drive components of these footrest structures need to bear the entire load applied by the user, placing high demands on the output load of the drive components. Summary of the Invention

[0003] On the one hand, in order to solve the above problems, this application provides a footrest device that can prevent the entire load borne by the footrest support plate from being transferred to the drive component.

[0004] On the other hand, in order to solve the above problems, this application provides a vehicle that can effectively support the user's feet and improve the user's riding comfort.

[0005] On one hand, this application provides a footrest device, which includes a mounting base, a footrest connecting plate, a footrest support plate, and a drive assembly. The front end of the footrest connecting plate is rotatably connected to the mounting base, the front end of the footrest support plate is rotatably connected to the footrest connecting plate, and the rear end of the footrest support plate is rotatably connected to the mounting base. The footrest support plate has a hidden state and a raised state. In the hidden state, the footrest support plate is in contact with the mounting base. In the raised state, the front end of the footrest support plate is raised upward and the front end of the footrest support plate is higher than the rear end. The footrest support plate, the footrest connecting plate, and the mounting base form a quadrilateral structure. The drive assembly is disposed on the mounting base and connected to the footrest connecting plate. The drive assembly can drive the footrest support plate to switch between the hidden state and the raised state.

[0006] Specifically, in the first aspect, in the raised state, the footrest support plate, the footrest connecting plate, and the mounting base form a quadrilateral structure. At this time, the force exerted by the user's foot on the footrest support plate can be decomposed into a vertically downward component and a horizontally forward component. The horizontally forward component acts directly on the mounting base through the footrest connecting plate. This horizontally forward component is not transmitted to the drive assembly, thereby reducing the load on the drive assembly. This helps to prevent the drive assembly from bearing a large load for a long time during use and can help extend the service life of the drive assembly. Secondly, since the rear end of the footrest support plate is rotatably connected to the mounting base, and the front end of the footrest support plate is rotatably connected to the footrest connecting plate, in the raised state, the footrest support plate only swings and lifts its front end relative to the mounting base, while the rear end remains connected to the mounting base. This design only requires applying a driving force to the front end of the footrest support plate, thus allowing the driving component to be positioned in front of the footrest support plate, unlike other solutions where the footrest support plate is raised as a whole relative to the mounting base, requiring the driving component to be positioned directly below the footrest support plate. This prevents the overall structure of the footrest device from encroaching too much on the space below the vehicle's horizontal floor (if the entire structure of the footrest device is placed on the vehicle's horizontal floor, it will inevitably encroach on the space below the vehicle's horizontal floor), avoiding the passive raising of the vehicle's horizontal floor or encroaching on the layout space of the power battery or other structures below. Thirdly, the design of the footrest connecting plate, with its front and rear ends connected to the drive assembly and the footrest support plate respectively, makes the footrest connecting plate a dual-function structure. On the one hand, the footrest connecting plate forms a transmission structure to realize the power transmission connection between the drive assembly and the footrest support plate; on the other hand, when the footrest support plate is in the raised state, the footrest connecting plate is in a nearly horizontal state, and the footrest connecting plate can form an auxiliary support structure to provide auxiliary support for the user's feet.

[0007] As a technical solution, the footrest device is installed on the horizontal floor of the vehicle's passenger compartment. The mounting base includes a rear floor plate and a forward-tilting plate disposed at the front end of the rear floor plate. The rear floor plate is used to connect with the horizontal floor plate. The forward-tilting plate is inclined upward in a direction from back to front. The footrest support plate is located above the rear floor plate. The front end of the footrest connecting plate is rotatably connected to the forward-tilting plate. In the hidden state, the footrest connecting plate is in contact with the forward-tilting plate. In the raised state, the footrest support plate, the footrest connecting plate, the forward-tilting plate, and the rear floor plate form a quadrilateral structure.

[0008] As a technical solution, in the raised state, the interior angle of the quadrilateral formed by the foot support plate and the rear base plate is greater than 0 degrees and less than or equal to 60 degrees.

[0009] As a technical solution, in the raised state, the footrest connecting plate is parallel to the rear bottom plate.

[0010] As a technical solution, the rear end of the rear base plate is provided with a first sliding structure, and the rear end of the foot support plate is provided with a second sliding structure. The first sliding structure and the second sliding structure are slidably connected and rotatably connected.

[0011] Specifically, by setting the foot support plate and the rear base plate to be slidably and rotatably connected, on the one hand, interference between the foot support plate and the mounting base can be avoided during the process of the foot support plate being raised and lowered by the foot support plate, and on the other hand, the reliability and stability of the raising and lowering of the foot support plate can be improved.

[0012] As a technical solution, the first sliding structure is a sliding groove, which extends along the front-rear direction and is disposed on the left and right sides of the rear end of the rear base plate. The second sliding structure is a sliding rod, which is disposed on the left and right sides of the rear end of the foot support plate and is inserted into the sliding groove.

[0013] Specifically, the sliding rod is a round rod, and the sliding rod and the sliding groove structure realize the sliding and rotating connection between the foot support plate and the rear bottom plate, making the foot support device simple and reliable in structure and low in production cost.

[0014] As a technical solution, the rear end of the rear base plate is also provided with an installation clearance port, which is located at the front end of the sliding groove, and the sliding rod can enter and leave the sliding groove through the installation clearance port.

[0015] Specifically, by providing the installation clearance opening, the sliding rod can be easily and conveniently installed into or removed from the sliding groove, improving the efficiency of early manufacturing and later maintenance.

[0016] As a technical solution, the mounting base also includes two hinged shaft seats, which are spaced apart in the left-right direction on the tilting plate;

[0017] The footrest device further includes a first hinge shaft and a second hinge shaft. The footrest connecting plate is rotatably connected to the two hinge shaft seats through the first hinge shaft and the second hinge shaft. The first hinge shaft is drive-connected to the drive assembly. The first hinge shaft rotates synchronously with the footrest connecting plate.

[0018] Specifically, on the one hand, the first hinge shaft is connected to the drive assembly, enabling the drive assembly to rotate the first hinge shaft, thereby rotating the footrest connecting plate relative to the forward tilting plate, and thus raising and lowering the front end of the footrest support plate; on the other hand, the horizontal forward component of the load borne by the footrest support plate can be transmitted through the footrest connecting plate to the first hinge shaft and the second hinge shaft, and then to the forward tilting plate, so that the forward tilting plate helps the drive assembly bear part of the load, thereby avoiding the drive assembly from bearing a large load for a long time during use, and helping to extend the service life of the drive assembly.

[0019] As a technical solution, an accommodating space is formed on the side or below the tilting plate, and the drive assembly is disposed on the tilting plate and located within the accommodating space.

[0020] Specifically, in the concealed state, since the footrest support plate is flush with the rear floor plate and the drive assembly is not positioned above or below the rear floor plate, the flatness and height of the horizontal floor plate are similar to those of conventional vehicles without footrests, thus not affecting the user's legroom. When the footrest support plate is raised, its front end (the end closest to the forward-leaning plate) detaches from the rear floor plate, forming a noticeable upward protrusion close enough to the user, thus providing effective support for the user's feet. This design, while ensuring effective support for the user's feet, effectively reduces the design complexity of the footrest device and minimizes encroachment on the space beneath the vehicle's horizontal floor plate. Furthermore, on the one hand, this design of placing the footrest support plate on the rear bottom plate ensures that the footrest support plate is close enough to the user, thereby providing the user with better support. At the same time, it avoids the complex front and rear movement structure of the footrest support plate (if the footrest device is placed far away from the user, a certain front and rear movement structure is required so that the footrest can reach the user's feet during use), simplifying the overall structure of the footrest device and greatly reducing the design difficulty and manufacturing cost of the footrest device. On the other hand, this design of placing the drive component in the accommodating space on the left and right sides or below the front tilting plate ensures that the overall structure of the footrest device does not encroach too much on the space below the vehicle's horizontal floor (if the entire structure of the footrest device is placed on the vehicle's horizontal floor, it will inevitably encroach on the space below the vehicle's horizontal floor), avoiding the passive raising of the vehicle's horizontal floor or encroaching on the layout space of the power battery or other structures below.

[0021] As a technical solution, a first protrusion is provided on the top of the rear bottom plate, the first protrusion extends in the front-rear direction, and a relief groove is provided on the bottom of the foot support plate, the first protrusion being embedded in the relief groove.

[0022] Specifically, by setting the first protrusion and the clearance groove, the bending resistance of the rear bottom plate in the front-rear direction and the bending resistance of the foot support plate in the front-rear direction can be improved. Moreover, this design can keep the foot support plate and the rear bottom plate with a small overall thickness, avoiding the passive raising of the vehicle's horizontal bottom plate or encroachment on the layout space of the power battery or other structures below.

[0023] As a technical solution, the drive assembly includes a drive motor and a worm gear structure, wherein the drive motor is connected to the footrest connecting plate through the worm gear structure.

[0024] Specifically, the worm gear structure includes a worm connected to the output shaft of the drive motor and a worm wheel that is connected to the footrest connecting plate. By setting the worm gear structure, when the drive motor is not outputting power, the footrest connecting plate and the footrest support plate can achieve self-locking at any position within the stroke range. That is, the footrest support plate can be fixed at different angles, thereby achieving effective support for the feet of different users and improving the applicability of the footrest device to different users.

[0025] As a technical solution, the footrest device further includes a flexible outer shell, which covers the footrest support plate and the footrest connecting plate when the footrest support plate is in contact with the rear bottom plate.

[0026] Specifically, by providing the flexible outer shell on top, the foot support plate and the foot support connecting plate can be provided with dustproof and waterproof protection without hindering their movement, thereby improving the reliability and durability of the foot support device's motion structure.

[0027] On the other hand, embodiments of this application also provide a vehicle, which includes a seat and the aforementioned footrest device, the footrest device being disposed in front of the seat.

[0028] Specifically, by installing the footrest device in front of the seat, the user's feet can be effectively supported, thereby improving the user's riding comfort.

[0029] The beneficial effects of this application are:

[0030] First, in the raised state, the footrest support plate, the footrest connecting plate, and the mounting base form a quadrilateral structure. At this time, the force exerted by the user's foot on the footrest support plate can be decomposed into a vertically downward component and a horizontally forward component. The horizontally forward component acts directly on the mounting base through the footrest connecting plate. This horizontally forward component is not transmitted to the drive assembly, thereby reducing the load on the drive assembly. This helps to prevent the drive assembly from bearing a large load for a long time during use and can help extend the service life of the drive assembly.

[0031] Secondly, since the rear end of the footrest support plate is rotatably connected to the mounting base, and the front end of the footrest support plate is rotatably connected to the footrest connecting plate, in the raised state, the footrest support plate only swings and lifts its front end relative to the mounting base, while the rear end remains connected to the mounting base. This design only requires applying a driving force to the front end of the footrest support plate, thereby allowing the driving component to be located in front of the footrest support plate. This prevents the overall structure of the footrest device from encroaching too much on the space under the vehicle's horizontal floor, avoiding the passive raising of the vehicle's horizontal floor or encroaching on the layout space of the power battery or other structures below.

[0032] Finally, the footrest device is installed in front of the vehicle's seat to effectively support the user's feet and improve the user's riding comfort. Attached Figure Description

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0043] Example 1:

[0044] This embodiment provides a footrest device, which is installed on the horizontal floor 100 of the passenger compartment of a vehicle, such as... Figure 1 As shown, the footrest device includes a mounting base 1, a drive assembly 2, a footrest support plate 3, and a footrest connecting plate 4. The front end of the footrest connecting plate 4 is rotatably connected to the mounting base 1, the front end of the footrest support plate 3 is rotatably connected to the footrest connecting plate 4, and the rear end of the footrest support plate 3 is rotatably connected to the mounting base 1. The footrest support plate 3 has a concealed state (e.g., ...). Figure 5 (as shown) and the raised state (as shown) Figure 6 As shown), in the hidden state, the footrest support plate 3 is attached to the mounting base 1. In the raised state, the front end of the footrest support plate 3 is raised upwards and the front end of the footrest support plate 3 is higher than the rear end. The footrest support plate 3, the footrest connecting plate 4, and the mounting base 1 form a quadrilateral structure. The drive component 2 is located on the mounting base 1 and is connected to the footrest connecting plate 4. The drive component 2 can drive the footrest support plate 3 to switch between the hidden state and the raised state. (Note: During use, the footrest device is placed in front of the seat. Here, "front" refers to the direction in which the user's feet are facing when sitting in the seat. This "front" is not necessarily the same as the front of the vehicle. Specifically, under normal circumstances, this "front" is the same as the conventional understanding of the front of the vehicle. However, if the seating direction is rearward, that is, the user's feet are facing the rear of the vehicle when sitting in the seat, then this "front" is opposite to the direction in which the front of the vehicle is pointed. The terms "front," "rear," "left," and "right" in this application are defined relative to the definition of "front" here.)

[0045] Specifically, in the first aspect, when the footrest support plate 3, footrest connecting plate 4, and mounting base 1 form a quadrilateral structure, the force exerted by the user's foot on the footrest support plate 3 can be decomposed into a vertically downward component and a horizontally forward component. The horizontally forward component acts directly on the mounting base 1 through the footrest connecting plate 4. This horizontally forward component is not transmitted to the drive component 2, thereby reducing the load on the drive component 2. This helps to prevent the drive component 2 from bearing a large load for a long time during use, which can help extend the service life of the drive component 2. Furthermore, during use, the user may apply a large load to the footrest support plate 3 at a certain moment (for example, when the user adjusts their sitting posture). The above structure can use the mounting base 1 to bear a part of the large force applied by the user (i.e., the horizontally forward component) instead of the drive component 2, thus avoiding the drive component 2 bearing a large load. Secondly, since the rear end of the footrest support plate 3 is rotatably connected to the mounting base 1 and the front end of the footrest support plate 3 is rotatably connected to the footrest connecting plate 4, in the raised state, the footrest support plate 3 only swings and lifts relative to the mounting base 1 at the front end, while the rear end remains connected to the mounting base 1. This design only requires applying a driving force to the front end of the footrest support plate 3, thus allowing the drive component 2 to be placed in front of the footrest support plate 3, instead of having to place the drive component 2 directly below the footrest support plate 3 as in other solutions where the footrest support plate 3 is raised as a whole relative to the mounting base 1. This prevents the overall structure of the footrest device from encroaching too much on the space below the vehicle body horizontal floor 100 (if the entire structure of the footrest device is placed on the vehicle body horizontal floor 100, it will inevitably encroach on the space below the vehicle body horizontal floor 100), thus avoiding the passive raising of the vehicle body horizontal floor 100 or encroaching on the layout space of the power battery or other structures below. Thirdly, the design of the footrest connecting plate 4, which is connected to the drive component 2 and the footrest support plate 3 at its front and rear ends respectively, makes the footrest connecting plate 4 a dual-function structure. On the one hand, the footrest connecting plate 4 forms a transmission structure to realize the power transmission connection between the drive component 2 and the footrest support plate 3; on the other hand, when the footrest support plate 3 is in the raised state, the footrest connecting plate 4 is in a nearly horizontal state, and the footrest connecting plate 4 can form an auxiliary support structure to provide auxiliary support for the user's feet.

[0046] In one embodiment, the mounting base 1 includes a rear base plate 11 and a forward tilting plate 12 disposed at the front end of the rear base plate 11. The rear base plate 11 is used to connect with a horizontal base plate 100. The forward tilting plate 12 is tilted upward in a direction from back to front. The foot support plate 3 is located above the rear base plate 11. The front end of the foot support connecting plate 4 is rotatably connected to the forward tilting plate 12. In the hidden state, the foot support connecting plate 4 is in contact with the forward tilting plate 12. In the raised state, the foot support plate 3, the foot support connecting plate 4, the forward tilting plate 12 and the rear base plate 11 form a quadrilateral structure (during the raising process, at certain moments the foot support plate 3 and the foot support connecting plate 4 are on the same straight line, at which time the four form a triangular structure).

[0047] like Figure 3 As shown, the footrest device also includes a hinged long shaft 5, which passes through the rear end of the footrest connecting plate 4 and the front end of the footrest support plate 3, thereby realizing the rotatable connection between the footrest connecting plate 4 and the footrest support plate 3.

[0048] In one embodiment, in the raised state, the foot support plate 3, foot support connecting plate 4, forward tilting plate 12 and rear bottom plate 11 form a quadrilateral structure that is trapezoidal or parallelogram, that is, in the raised state, the foot support connecting plate 3 is parallel to the rear bottom plate 11.

[0049] In one embodiment, when the footrest support plate 3 and the rear base plate 11 are in the raised state, the interior angle of the quadrilateral formed by them is greater than 0 degrees and less than or equal to 60 degrees. In specific implementation, this interior angle can be 5 degrees, 10 degrees, 15 degrees, 20 degrees, 25 degrees, 30 degrees, 35 degrees, 40 degrees, 45 degrees, 50 degrees, or 55 degrees.

[0050] In one embodiment, a first sliding structure is provided at the rear end of the rear base plate 11, and a second sliding structure is provided at the rear end of the footrest support plate 3. The first sliding structure and the second sliding structure are slidably and rotatably connected. Specifically, by setting the footrest support plate 3 and the rear base plate 11 to be slidably and rotatably connected, interference between the footrest connecting plate 4 and the mounting base 1 can be avoided during the lifting and lowering of the footrest support plate 3, and the reliability and stability of the lifting and lowering of the footrest support plate 3 can be improved. The slidably and rotatably connected structure here can be a sliding hinge, or other structures that simultaneously achieve sliding and rotational relationships.

[0051] Furthermore, in the specific implementation process, such as Figure 2 and Figure 4As shown, the first sliding structure is a sliding groove 13, which extends along the front-rear direction and is located on the left and right sides of the rear end of the rear base plate 11, with the sliding grooves 13 on the left and right sides arranged symmetrically. The second sliding structure is a sliding rod 31, which is located on the left and right sides of the rear end of the foot support plate 3 and is inserted into the sliding groove 13. Specifically, the sliding rod 31 is a round rod. The sliding rod 31 and the sliding groove 13 structure enable a sliding and rotating connection between the foot support plate 3 and the rear base plate 11, making the foot support device simple and reliable in structure and low in production cost.

[0052] Of course, in some other embodiments, it can also be designed as follows: the first sliding structure is a sliding rod 31, which is disposed on the left and right sides of the rear end of the rear base plate 11; the second sliding structure is a sliding groove 13, which extends in the front-back direction and is disposed on the left and right sides of the rear end of the foot support plate 3; the sliding rod 31 is inserted into the sliding groove 13.

[0053] In one embodiment, such as Figure 4 As shown, the rear end of the rear base plate 11 is also provided with an installation clearance port 14, which is located at the front end of the sliding groove 13. The sliding rod 31 can enter and leave the sliding groove 13 through the installation clearance port 14. Specifically, by providing the installation clearance port 14, the sliding rod 31 can be easily and conveniently installed into or removed from the sliding groove 13, improving the efficiency of early manufacturing and later maintenance.

[0054] Furthermore, the installation clearance port 14 is located at the top of the sliding groove 13. The length of the sliding groove 13 is greater than the maximum stroke of the foot support plate 3 during actual use. This design can prevent the sliding rod 31 from sliding to the front end of the sliding groove 13 and disengaging from the sliding groove 13 through the installation clearance port 14, thus ensuring a reliable connection between the foot support plate 3 and the rear base plate 11 during use.

[0055] In one embodiment, such as Figure 2As shown, the mounting base 1 also includes two hinged shaft seats 15, which are spaced apart in the left-right direction on the forward tilting plate 12. The footrest device also includes a first hinge shaft 6 and a second hinge shaft 7. The footrest connecting plate 4 is rotatably connected to the two hinged shaft seats 15 through the first hinge shaft 6 and the second hinge shaft 7. The first hinge shaft 6 is also connected to the drive assembly 2, and the first hinge shaft 6 rotates synchronously with the footrest connecting plate 4. Specifically, on the one hand, the drive assembly 2 is connected to the first hinge shaft 6 through the first hinge shaft 6, enabling the drive assembly 2 to drive the first hinge shaft 6 to rotate, thereby realizing the rotation of the footrest connecting plate 4 relative to the forward tilting plate 12, thus realizing the lifting and lowering of the front end of the footrest support plate 3. On the other hand, the horizontal forward component of the load borne by the footrest support plate 3 can be transmitted through the footrest connecting plate 4 to the first hinge shaft 6 and the second hinge shaft 7, and then to the forward tilting plate 12. This allows the forward tilting plate 12 to help the drive assembly 2 bear part of the load, thereby preventing the drive assembly 2 from bearing a large load for a long time during use and helping to extend the service life of the drive assembly 2.

[0056] Furthermore, in the specific implementation process, such as Figure 1 and Figure 2 As shown, the drive assembly 2 is located at the upper right end of the inclinometer plate 12, and the first hinge shaft 6 is mounted on the hinge shaft seat 15 on the right side of the inclinometer plate 12. A connecting gear 8 is mounted on the first hinge shaft 6, and the connecting gear 8 meshes with the drive assembly 2.

[0057] In one embodiment, a receiving space is formed to the side or below the tilting plate 12, and the drive assembly 2 is disposed on the tilting plate 12 and located within the receiving space. Specifically, as shown... Figure 5 and Figure 6As shown, when the footrest support plate 3 is in the hidden state, since the footrest support plate 3 is in contact with the rear floor plate 11 and the drive component 2 is not located above or below the rear floor plate 11, the flatness and height of the horizontal floor plate 100 are similar to those of a conventional vehicle without a footrest device, thus not affecting the user's leg and foot placement space. When the footrest support plate 3 is in the raised state, the end of the footrest support plate 3 near the forward tilt plate 12 (i.e., the front end of the footrest support plate 3) is detached from the rear floor plate 11, forming a noticeable upward protrusion structure at a position sufficiently close to the user, thus providing effective support for the user's feet. This design, while ensuring effective support for the user's feet, effectively reduces the design difficulty of the footrest device and the encroachment on the space below the vehicle's horizontal floor plate 100. Furthermore, on the one hand, this design of placing the footrest support plate 3 on the rear bottom plate 11 ensures that the footrest support plate 3 is close enough to the user, thereby providing the user with better support. At the same time, it avoids the complex front and rear movement structure of the footrest support plate 3 (if the footrest device is placed far away from the user, a certain front and rear movement structure is required so that the footrest can reach the user's feet during use), simplifying the overall structure of the footrest device and greatly reducing the design difficulty and manufacturing cost of the footrest device. On the other hand, this design of placing the drive component 2 in the accommodating space on the left and right sides or below the front tilt plate 12 ensures that the overall structure of the footrest device does not encroach too much on the space below the vehicle body horizontal bottom plate 100 (if the entire structure of the footrest device is placed on the vehicle body horizontal bottom plate 100, it will inevitably encroach on the space below the vehicle body horizontal bottom plate 100), avoiding the vehicle body horizontal bottom plate 100 being passively raised or encroaching on the layout space of the power battery or other structures below.

[0058] In a specific embodiment, the footrest device is used inside the vehicle in conjunction with a zero-gravity seat. When the zero-gravity seat is adjusted to a zero-gravity state, the footrest support plate 3 of the footrest device adaptively lifts and supports the user's feet (e.g., ...). Figure 6 (As shown). Furthermore, the zero-gravity seat is located in the passenger seat, the footrest is located below the passenger glove box, the rear floor 11 is in contact with the horizontal floor 100 of the vehicle body, the forward tilting plate 12 is in contact with the tilting plate 200 below the passenger glove box, and the storage space is also located below the passenger glove box.

[0059] In one embodiment, such as Figure 2 As shown, a first protrusion 16 is provided on the top of the rear base plate 11. The first protrusion 16 extends in the front-rear direction. A relief groove 32 is provided at the bottom of the foot support plate 3. The first protrusion 16 is embedded in the relief groove 32.

[0060] Specifically, by setting the first protrusion 16 and the clearance groove 32, the bending resistance of the rear bottom plate 11 in the front-rear direction and the bending resistance of the foot support plate 3 in the front-rear direction can be improved. Moreover, this design can keep the foot support plate 3 and the rear bottom plate 11 with a small overall thickness, avoiding the passive raising of the vehicle body horizontal bottom plate 100 or encroaching on the layout space of the power battery or other structures below.

[0061] Furthermore, in the specific implementation process, such as Figure 2 As shown, a second protrusion 17 is also provided on the top of the rear base plate 11. The second protrusion 17 extends in the left and right direction and can improve the bending resistance of the rear base plate 11 in the left and right direction.

[0062] In one embodiment, such as Figure 1 As shown, the drive assembly 2 includes a drive motor 21 and a worm gear structure 22. The drive motor 21 is connected to the footrest connecting plate 4 via the worm gear structure 22. Specifically, the worm gear structure 22 includes a worm connected to the output shaft of the drive motor 21 and a worm wheel connected to the footrest connecting plate 4. By setting the worm gear structure 22, when the drive motor 21 is not outputting power, the footrest connecting plate 4 and the footrest support plate 3 can achieve self-locking at any position within the stroke range, that is, the footrest support plate 3 can be fixed at different angles, thereby achieving effective support for the feet of different users and improving the applicability of the footrest device to different users.

[0063] Furthermore, such as Figure 1 As shown, the mounting base 1 also includes a drive cover 18, which is located at the upper right side of the tilting plate 12, and the drive assembly 2 is mounted on the drive cover 18.

[0064] Of course, in some other embodiments, the drive component 2 can also use a cylinder, hydraulic cylinder or other structure as the power source.

[0065] In one embodiment, such as Figure 1 As shown, the footrest device also includes a flexible outer shell 9, which covers the footrest support plate 3 and the footrest connecting plate 4 when the footrest support plate 3 is in contact with the rear base plate 11. Furthermore, the flexible outer shell 9 is a bent shell structure, and its initial bending angle is equal to the angle between the rear base plate 11 and the forward tilting plate 12. Specifically, by providing the flexible outer shell 9 on top, dust and water protection can be provided to the footrest support plate 3 and the footrest connecting plate 4 without hindering their movement, thereby improving the reliability and durability of the footrest device's motion structure.

[0066] In the specific implementation process, such as Figure 5 and Figure 6As shown, the flexible shell 9 has a ring structure. When the foot support plate 3 is in the hidden state, the flexible shell 9 covers the entire periphery of the foot support plate 3 and the foot support connecting plate 4. When the foot support plate 3 is in the raised state, the foot support plate 3 and the foot support connecting plate 4 pass upward through the flexible shell 9 from the middle position of the ring structure.

[0067] Of course, in some embodiments, the flexible shell 9 may also be designed as follows: the flexible shell 9 includes an upper shell and a side shell, the side shell is arranged around the periphery of the upper shell, and the side shell is fastened to the periphery of the foot support plate 3 and the foot support connecting plate 4, so as to realize the connection and fixation between the flexible shell 9 and the foot support plate 3 and the foot support connecting plate 4.

[0068] Of course, in some other embodiments, it can also be designed as follows: the flexible shell 9 covers the top of the mounting base 1 and covers the foot support plate 3 and the foot connecting plate 4. The flexible shell 9 includes an upper shell and a side shell. The side shell is arranged around the periphery of the upper shell and is fastened to the periphery of the mounting base 1 to realize the connection and fixation between the flexible shell 9 and the mounting base 1.

[0069] Example 2:

[0070] This embodiment provides a vehicle, such as Figure 5 and Figure 6 As shown, the vehicle includes a seat and a footrest device as described in Embodiment 1, with the footrest device positioned in front of the seat. Specifically, by providing a footrest device in front of the seat, the user's feet can be effectively supported, thereby improving the user's riding comfort.

[0071] In practice, the seat is a zero-gravity seat. When the zero-gravity seat is adjusted to a zero-gravity state, the footrest support plate 3 of the footrest device is adaptively raised to support the user's feet.

[0072] Furthermore, the seat is positioned in the front passenger seat, with the footrest located below the front passenger glove box. The rear floor 11 is flush with the horizontal floor 100 of the vehicle body, and the forward tilting plate 12 is flush with the inclined plate 200 below the front passenger glove box. Of course, the seat can also be a rear seat, with the footrest located between the rear seat and the front seat.
