Description

Technical Field

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

[0002] In the automotive industry, seats, as components that come into contact with passengers, typically have a direct impact on the riding experience due to their comfort.

[0003] In related technologies, seat design usually focuses on torso support and posture adjustment. Such a design is not conducive to meeting the needs of passengers of different heights and in various application scenarios for seat comfort, and is not conducive to improving seat comfort. Utility Model Content

[0004] In view of this, this application aims to propose a footrest structure to improve the comfort of the seat.

[0005] To achieve the above objectives, the technical solution of this application is implemented as follows: A footrest structure, suitable for mounting on a seat, includes a mounting base, a footrest mounted on the mounting base, and a locking portion and a first elastic portion disposed between the mounting base and the footrest; The mounting base is used to install the footrest structure on the front or rear side of the seat. The footrest can rotate relative to the mounting base and switch between a storage state and a use state. In the storage state, the footrest is folded on the front or rear side of the seat. In the use state, the footrest unfolds outwards from the seat to support the feet. The locking part is used to lock the footrest in the stored state, and the first elastic part is used to drive the footrest to switch to the use state after the locking part is unlocked.

[0006] Furthermore, a limiting part is provided between the footrest and the mounting base, which is used to limit the rotation angle of the footrest when switching to the use state.

[0007] Furthermore, the footrest is provided with a connecting seat, the connecting seat has a connecting hole, the mounting base is provided with a rotating shaft, the end of the rotating shaft is provided with a swivel block, and the swivel block is rotatably inserted into the connecting hole; The limiting part includes a limiting surface provided on the inner wall of the connecting hole and a mating surface provided on the outer wall of the rotating block. The limiting surface abuts against the mating surface and can limit the rotation angle of the footrest.

[0008] Furthermore, the connecting seat is provided with a limiting block protruding into the connecting hole, the limiting surface is provided on the limiting block, and the limiting block has an abutting surface that is set at a preset angle with the limiting surface; when the footrest switches to the storage state, the abutting surface can abut against the mating surface to limit the rotation angle of the footrest.

[0009] Furthermore, the locking part includes a locking hole on the mounting base, a locking pin slidably disposed on the footrest, and a second elastic part disposed between the locking pin and the footrest; under the pushing of the second elastic part, the locking pin can be inserted into the locking hole to lock the footrest in the stored state.

[0010] Furthermore, the footrest is rotatably provided with a lever, which passes through the locking pin; by manipulating the lever, the locking pin can be driven to slide out of the locking hole to unlock the footrest.

[0011] Furthermore, the footrest is provided with a locking seat, the locking seat is provided with a sliding hole, the locking pin is slidably disposed in the sliding hole, and one end of the locking pin is used to insert into the locking hole, and the other end has a through hole, the through hole extending along the sliding direction of the locking pin; one end of the toggle is rotatably disposed on the mounting base, and the other end passes through the through hole, and the second elastic part includes a spring disposed in the sliding hole.

[0012] Furthermore, the locking pin is provided with a guide slope, which can guide the locking pin to be inserted into the lock hole.

[0013] Furthermore, the front side of the seat is provided with a receiving groove, and the footrest in the stored state is received in the receiving groove, with the front side of the footrest flush with the front side of the seat.

[0014] Compared with related technologies, this application has the following advantages: (1) The footrest structure described in this application allows it to switch between a storage state and a use state. When the footrest is not in use, it can be stored to prevent interference with the passenger. When the footrest is in use, it can support the passenger's feet, thereby meeting the needs of passengers of different heights and in various application scenarios for seat comfort and improving the seating comfort.

[0015] Meanwhile, the locking mechanism allows the footrest to fold stably in front of or behind the seat, thus reducing its footprint and minimizing interference with passengers. Furthermore, after releasing the locking mechanism, the first elastic element allows the footrest to automatically switch from its folded state to its usable state, further enhancing its ease of use.

[0016] (2) By setting a limiting part, the rotation angle of the footrest can be limited to avoid the footrest from being over-extended. Furthermore, the limiting part restricts the rotation angle of the footrest, so that the footrest can bear the pressure applied by the passenger's feet and maintain its use state, which is conducive to ensuring the reliability of the footrest.

[0017] (3) By allowing the rotating block to rotatably pass through the connecting hole, it is beneficial to make the rotating shaft rotate smoothly without jamming. At the same time, by setting the limiting surface to abut against the mating surface, the rotation angle of the footrest is limited, without the need for additional limiting components, which can reduce the space occupied by the limiting part and make the footrest structure easier to design and implement.

[0018] (4) By setting a limiting block and making the limiting block have an abutting surface, it is beneficial to limit the rotation angle when the footrest is stored, and to keep the footrest in the preset storage posture, thereby ensuring the consistency of the seat appearance and the quality of the seat appearance.

[0019] (5) By providing a locking part including a second elastic part, the pushing action of the second elastic part helps to insert and retain the locking pin in the lock hole, which helps to ensure the stability of the footrest when it is in the storage state. At the same time, by compressing the second elastic part, the locking pin can be disengaged from the lock hole, and under the action of the first elastic part, the footrest can automatically switch from the storage state to the use state, which also makes the footrest more convenient to use.

[0020] (6) By setting a toggle through the lock cylinder, the sliding of the lock cylinder can be converted into the rotation of the toggle, which makes it easier to apply force to the lock cylinder and make the lock cylinder disengage from the lock hole, which is conducive to unlocking the locking part and has good operational convenience.

[0021] (7) By setting a through hole extending along the sliding direction of the lock pin and allowing the lever to pass through the through hole, the transmission connection between the lever and the lock pin is realized. The structure is simple and easy to design and implement. Moreover, it is also convenient to disengage the lock pin from the lock hole by using the lever, which helps to ensure the ease of unlocking the locking part. At the same time, the lever passing through the through hole also helps to keep the lock pin in the sliding hole, preventing the lock pin from disengaging from the locking seat, which helps to ensure the reliability of the locking part.

[0022] (8) By setting a guide slope, the lock pin can slide and the second elastic part can be compressed by the guiding effect of the guide slope. When the lock pin corresponds to the lock hole, the lock pin is inserted into the lock hole under the reset effect of the second elastic part. While ensuring the locking reliability of the locking part, it is beneficial to improve the locking convenience of the locking part.

[0023] (9) By setting up a receiving slot, the footrest can be flush with the seat, which helps to reduce the space occupied by the footrest when it is in the storage state. In addition, the fact that the footrest is flush with the seat can prevent the footrest from protruding from the seat when it is in the storage state, which can prevent interference to passengers and also help to ensure the appearance quality of the seat.

[0024] Another object of this application is to provide a vehicle in which the seat is provided with the footrest structure described above.

[0025] The vehicle described in this application, by providing a footrest structure on the vehicle seat as described above, can improve the comfort and functionality of the seat, thereby improving the quality of the vehicle. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application in light of the specific circumstances.

[0031] In this application, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0032] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0033] An embodiment of the first aspect of this application provides a footrest structure suitable for mounting on a seat 1, which can support the passenger's feet to improve the comfort of the seat 1. Furthermore, through innovative design, the footrest structure can switch between a folded state S1 and a usage state S2 to meet the needs of different users, thereby improving the functionality of the seat 1.

[0034] In related technologies, the design of seat 1 usually focuses on supporting the passenger's torso and adjusting posture. Since the seat cushion of seat 1 is a certain height from the vehicle floor, this setting makes it easy for shorter passengers or passengers sitting in child seats 1 to have their feet dangling in the air, which is not conducive to meeting the comfort needs of passengers of different heights and in various application scenarios, and is not conducive to improving the comfort of seat 1.

[0035] In view of this, in order to overcome the shortcomings of related technologies, the footrest structure of this embodiment combines... Figures 1 to 9As shown, the overall design includes a mounting base 2, a footrest 3 mounted on the mounting base 2, and a locking part 4 and a first elastic part 5 located between the mounting base 2 and the footrest 3. The mounting base 2 is used to mount the footrest structure on the front or rear side of the seat 1. The footrest 3 can rotate relative to the mounting base 2 and switch between a folded state S1 and a usage state S2. In the folded state S1, the footrest 3 is folded on the front or rear side of the seat 1. In the usage state S2, the footrest 3 unfolds outwards from the seat 1 to support the feet. The locking part 4 is used to lock the footrest 3 in the folded state S1, and the first elastic part 5 is used to drive the footrest 3 to switch to the usage state S2 after the locking part 4 is unlocked.

[0036] Therefore, by allowing the footrest structure to switch between a retracted state S1 and a usable state S2, the footrest 3 can be retracted in state S1 when not in use, preventing interference with passengers. When short passengers or children sit in seat 1, the footrest 3 can be put into usable state S2, supporting the passenger's feet. This helps meet the comfort needs of passengers of different heights and in various application scenarios, thus improving the seating comfort of seat 1.

[0037] Meanwhile, by providing the locking part 4, the footrest 3 can be stably folded in front of or behind the seat 1, thus placing the footrest 3 in the stowed state S1, which reduces the space occupied in the vehicle and effectively prevents interference with passengers. Furthermore, after releasing the locking part 4 from the footrest 3, the first elastic part 5 allows the footrest 3 to automatically switch from the stowed state S1 to the use state S2, improving the ease of use of the footrest 3.

[0038] Based on the above overview, it is understood that, in specific implementation, the footrest structure can be set on the front side of seat 1 as needed for the feet of passengers sitting on seat 1, and can also be set on the rear side of seat 1 to support the feet of passengers in the rear seats 1.

[0039] This embodiment specifically illustrates the use of a footrest structure located on the front side of seat 1 as an example. Preferably, this footrest structure is located on the front side of the seat cushion of seat 1. When the footrest 3 is unfolded outward from its folded-in storage state S1 on the front side of seat 1 and is in its use state S2, the footrest 3 is parallel to the vehicle floor to support the feet of the passenger on seat 1. Furthermore, at this time, the footrest 3 unfolds outward in the longitudinal direction of the vehicle, that is, it unfolds towards the side closer to the front of the vehicle.

[0040] When the footrest structure is located behind seat 1, it is positioned behind the backrest or the seat cushion of seat 1, allowing rear passengers to use it. In this case, the footrest 3 unfolding outwards means unfolding rearwards along the vehicle's longitudinal direction, i.e., towards the rear of the vehicle. It can be understood that when the footrest structure is located behind seat 1, the unfolded footrest 3 is parallel to the vehicle floor, allowing rear passengers to step on it and have their feet supported.

[0041] It is worth noting that one of the functions of the mounting base 2 is to support the footrest 3, so that the footrest 3 can be connected to the seat 1 and can support the passenger's feet when the footrest 3 is in use state S2. In a specific implementation, the mounting base 2 includes a first connecting part 201, which can be connected to the frame 101 of the seat 1 and can be rotatably connected to the footrest 3.

[0042] In some of the exemplary implementations, combined with Figure 4 as well as Figures 9 to 12 As shown, a limiting part 6 is provided between the footrest 3 and the mounting base 2. The limiting part 6 is used to limit the rotation angle of the footrest 3 when switching to the use state S2.

[0043] Therefore, by setting the limiting part 6, the rotation angle of the footrest 3 can be limited, so as to prevent the footrest 3 from being over-extended. Furthermore, the limiting part 6 restricts the rotation angle of the footrest 3, so that the footrest 3 can bear the pressure applied by the passenger's feet and maintain the use state S2, which helps to ensure the reliability of the footrest 3.

[0044] In some of the exemplary implementations, combined with Figure 4 as well as Figures 9 to 12 As shown, the footrest 3 is provided with a connecting seat 601, and the connecting seat 601 has a connecting hole 602. The mounting base 2 is provided with a rotating shaft 603, and the end of the rotating shaft 603 is provided with a rotating block 604, which is rotatably inserted into the connecting hole 602. The limiting part 6 includes a limiting surface 602a provided on the inner wall of the connecting hole 602, and a mating surface 604a provided on the outer wall of the rotating block 604. The limiting surface 602a abuts against the mating surface 604a, which can limit the rotation angle of the footrest 3.

[0045] Therefore, by allowing the rotating block 604 to rotatably pass through the connecting hole 602, it is beneficial to ensure that the rotating shaft 603 rotates smoothly without jamming. At the same time, by setting the limiting surface 602a to abut against the mating surface 604a, the rotation angle of the footrest 3 is limited, without the need for additional limiting components, which can reduce the space occupied by the limiting part 6 and make the footrest structure easier to design and implement.

[0046] Based on the above general introduction, in detail, as follows: Figure 9 As shown, the first connecting portion 201 includes a first connecting piece 2011 and a first supporting piece 2012. The first connecting piece 2011 can fixably connect the frame 101 and the first supporting piece 2012. The first supporting piece 2012 has an extension portion 2013 extending towards the connecting seat 601. The rotating shaft 603 is inserted into the extension portion 2013 and fixedly connected to the extension portion 2013, so that the connecting seat 601 can rotate relative to the extension portion 2013, and the footrest 3 is connected to the extension portion 2013 through the connecting seat 601, thereby allowing the footrest 3 to be rotatably connected to the mounting base 2.

[0047] In specific implementation, at least two first connecting parts 201 are provided, and each first connecting part 201 is correspondingly provided with a connecting seat 601. Preferably, in this embodiment, first connecting parts 201 are provided at both ends of the footrest 3 along the length direction of the footrest 3. That is, first connecting parts 201 are provided at both ends of the footrest 3 along the left-right direction of the whole vehicle. This arrangement helps to improve the installation reliability of the footrest 3.

[0048] It is worth noting that, based on the above overall description, as an optional implementation of the first elastic part 5, in this embodiment, the first elastic part 5 is set as a torsion spring. In specific implementation, the torsion spring is sleeved on the rotating shaft 603, and one end of the torsion spring abuts against the first bearing plate 2012, and the other end abuts against the connecting seat 601, so as to drive the connecting seat 601 to rotate, thereby driving the footrest 3 to switch to the use state S2.

[0049] Understandably, to effectively ensure the reliability of the connection between the first connecting part 201 and the frame 101, in this embodiment, the first connecting piece 2011 is fixed to the frame 101 by welding. Furthermore, to facilitate the assembly of the footrest structure onto the seat 1, in this embodiment, the first supporting piece 2012 is screwed together with the first connecting piece 2011. For example, self-tapping screws are used to connect the first supporting piece 2012 and the first connecting piece 2011. Simultaneously, to facilitate the connection between the footrest 3 and the connecting seat 601, in this embodiment, the footrest 3 is screwed together with the connecting seat 601, for example, using self-tapping screws.

[0050] In some of the exemplary implementations, combined with Figures 9 to 12 As shown, the connecting base 601 is provided with a limiting block 605 protruding into the connecting hole 602. A limiting surface 602a is provided on the limiting block 605, and the limiting block 605 has an abutting surface 602b that is set at a preset angle with the limiting surface 602a. When the footrest 3 switches to the storage state S1, the abutting surface 602b can abut against the mating surface 604a to limit the rotation angle of the footrest 3.

[0051] Therefore, by setting the limiting block 605 and making the limiting block 605 have an abutment surface 602b, it is beneficial to limit the rotation angle of the footrest 3 when it is stored, and to make the footrest 3 maintain the preset storage posture, thereby helping to ensure the appearance consistency of the seat 1 and the appearance quality of the seat 1.

[0052] Based on the above overview, it is worth noting that in specific implementation, the limiting block 605 is designed as a fan-shaped plate with a 90° cross-section. The two vertical surfaces of the limiting block 605 serve as the limiting surface 602a and the abutment surface 602b, respectively. Furthermore, the radius of the connecting hole 602 is the same as the radius of the limiting block 605, and the limiting block 605 is positioned within the connecting hole 602, making the connecting hole 602 a fan-shaped hole with a 270° cross-section.

[0053] Meanwhile, the rotating block 604 is set in a semi-cylindrical shape, and the diameter of the rotating block 604 is the same as the diameter of the connecting hole 602. That is, the cross-section of the rotating block 604 is a 180° sector, and the plane of the rotating block 604 serves as the mating surface 604a. As configured above, by causing the limiting block 605 to rotate around the rotating block 604, the mating surface 604a abuts against the limiting surface 602a or the abutting surface 602b, thereby placing the footrest 3 in either the storage state S1 or the use state S2.

[0054] Of course, it is understood that the above description is only a preferred embodiment of this example. When the cross-section of the limiting block 605, the cross-section of the rotating block 604, or the size of the opening of the connecting hole 602 changes, it is possible to enable the footrest 3 to switch between the storage state S1 and the use state S2.

[0055] It is worth noting that, in order to effectively ensure the stability of the connection between the limiting block 605 and the connecting seat 601, in this embodiment, the limiting block 605 and the connecting seat 601 are integrally formed. In specific implementation, the connecting hole 602 is formed on the connecting seat 601 by milling, so that the connecting seat 601 has the limiting block 605.

[0056] In some of the exemplary implementations, combined with Figures 4 to 8 As shown, the locking part 4 includes a locking hole 4a provided on the mounting base 2, a locking pin 401 slidably provided on the footrest 3, and a second elastic part 402 provided between the locking pin 401 and the footrest 3. Under the pushing of the second elastic part 402, the locking pin 401 can be inserted into the locking hole 4a to lock the footrest 3 in the retracted state S1.

[0057] Therefore, by providing the locking part 4 with a second elastic part 402, the pushing action of the second elastic part 402 facilitates the insertion and retention of the locking pin 401 within the locking hole 4a, thus ensuring the stability of the footrest 3 in the retracted state S1. Simultaneously, by compressing the second elastic part 402, the locking pin 401 can disengage from the locking hole 4a, and under the action of the first elastic part 5, the footrest 3 automatically switches from the retracted state S1 to the usage state S2.

[0058] Based on the above description, another function of the mounting base 2 is to lock the footrest 3 onto the seat 1 via the locking part 4, thereby placing the footrest 3 in the retracted state S1. In a specific implementation, the mounting base 2 is provided with a second connecting part 202, which can be connected to the frame 101 and can form a locking hole 4a for the locking pin 401 to be inserted.

[0059] Specifically, the second connecting part 202 includes a second connecting piece 2021 and a locking piece 2022. The second connecting piece 2021 connects the frame 101 and the locking piece 2022. The locking piece 2022 is bent into an n-shape and fixed to the second connecting piece 2021 to form a lock hole 4a.

[0060] As an optional embodiment of the locking part 4's placement, in this embodiment, the locking part 4 is positioned along the length of the footrest 3 at the middle of the footrest 3, and the locking part 4 is located in the upper half of the footrest 3 when the footrest 3 is in the retracted state S1. Furthermore, in this embodiment, the second connecting piece 2021 extends upwards along the vertical direction of the entire vehicle, so that the locking pin 401 can be inserted into the locking hole 4a.

[0061] In some of the exemplary implementations, combined with Figure 5 , Figure 7 and Figure 8 As shown, a lever 403 is rotatably mounted on the footrest 3, and the lever 403 passes through the locking pin 401. By rotating the lever 403, the locking pin 401 can be driven to slide and disengage from the locking hole 4a, thereby unlocking the footrest 3.

[0062] Therefore, by setting the toggle 403 through the lock pin 401, the sliding of the lock pin 401 can be converted into the rotation of the toggle 403, which makes it easier to apply force to the lock pin 401 and make the lock pin 401 disengage from the lock hole 4a, which is beneficial to unlocking the locking part 4.

[0063] In some of the exemplary implementations, combined with Figure 5 , Figure 7 and Figure 8As shown, the footrest 3 is provided with a locking seat 404, which has a sliding hole 404a. The locking pin 401 is slidably disposed in the sliding hole 404a, and one end of the locking pin 401 is used to insert into the locking hole 4a, while the other end has a through hole 401a that extends along the sliding direction of the locking pin 401. One end of the toggle knob 403 is rotatably disposed on the mounting base 2, and the other end passes through the through hole 401a. The second elastic part 402 includes a spring disposed in the sliding hole 404a.

[0064] Therefore, by providing a through hole 401a extending along the sliding direction of the locking pin 401, and allowing the lever 403 to pass through the through hole 401a, it is easy to disengage the locking pin 401 from the lock hole 4a by using the lever 403, which helps to ensure the ease of unlocking the locking part 4. At the same time, the lever 403 passing through the through hole 401a also helps to keep the locking pin 401 in the sliding hole 404a, preventing the locking pin 401 from disengaging from the locking seat 404, thus helping to ensure the reliability of the locking part 4.

[0065] Based on the above overview, it is worth noting that, as Figure 7 As shown, in a specific implementation, the locking seat 404 includes a guide tube 4041, an ear plate 4042, and a fixing part 4043. A sliding hole 404a is formed on the guide tube 4041 along its axial direction to allow the locking pin 401 to be inserted. The ear plate 4042 is fixedly connected to both sides of the guide tube 4041 to facilitate the overall connection of the locking seat 404 to the foot support 3. The fixing part 4043 is located at one end of the locking pin 401 with a through hole 401a along its axial direction, and a clearance groove is formed on the fixing part 4043 along its axial direction. A toggle switch 403, with one end rotatably mounted on the mounting base 2, is inserted into the clearance groove and rotatably connected to the fixing part 4043 to achieve a rotatable connection with the mounting base 2.

[0066] like Figure 7 As shown in the diagram, as an optional embodiment of the toggle switch 403, in this embodiment, the toggle switch 403 includes a guide portion 4031 and a pressing portion 4032. One end of the guide portion 4031 is inserted into the relief groove and hinged to the fixing portion 4043, and the other end extends at a certain angle into the through hole 401a and connects to the pressing portion 4032. The locking pin 401 is formed with a guide slope 401c adapted to the guide portion 4031. With this configuration, when the toggle switch 403 is operated, the guide portion 4031 pushes the locking pin 401 to slide in the sliding hole 404a under the action of the guide slope 401c, which can effectively reduce the wear between the toggle switch 403 and the device. Furthermore, the diameter of the through hole 401a is larger than the thickness of the pressing portion 4032, which also allows the toggle switch 403 to press and rotate, driving the locking pin 404 to slide, thereby unlocking the footrest 3.

[0067] It is worth noting that, based on the guide tube 4041 included in the locking seat 404, as a specific assembly method of the second elastic part 402, in this embodiment, the inner wall of the guide tube 4041 is provided with a groove 4041a, the spring is sleeved on the locking post 401, and one end of the spring abuts against the bottom wall of the groove 4041a, and the other end is connected to the locking post 401.

[0068] In some of the exemplary implementations, combined with Figure 7 and Figure 8 As shown, the locking pin 401 is provided with a guide slope 401b, which can guide the locking pin 401 to be inserted into the lock hole 4a.

[0069] Therefore, by setting the guide slope 401b, the locking pin 401 can slide and the second elastic part 402 can be compressed by the guiding action of the guide slope 401b. When the locking pin 401 corresponds to the lock hole 4a, the locking pin 401 is inserted into the lock hole 4a under the reset action of the second elastic part 402. This ensures the locking reliability of the locking part 4 and improves the locking convenience of the locking part 4.

[0070] Understandably, when the footrest 3 is flipped from its active state S2 to its retracted state S1, with the locking plate 2022 in place, the guide ramp 401b will abut against the locking plate 2022 and continue to rotate as the footrest 3 rotates. Under the action of the guide ramp 401b, the rotational force can be decomposed into a force extending axially along the locking pin 401, thereby causing the second elastic part 402 to gradually align with the lock hole 4a. When the locking pin 401 is fully aligned with the lock hole 4a, the guide ramp 401b disengages from the locking plate 2022, and under the restoring force of the second elastic part 402, the locking pin 401 is inserted into the lock hole 4a.

[0071] In some of the exemplary implementations, combined with Figure 1 and Figure 2 As shown, the front side of the seat 1 is provided with a receiving groove 1a, and the footrest 3 in the storage state S1 is housed in the receiving groove 1a, and the front side of the footrest 3 is flush with the front side of the seat 1.

[0072] Therefore, by providing the receiving slot 1a, the footrest 3 is made flush with the seat 1, which helps to reduce the space occupied by the footrest 3 in the folded state S1. Furthermore, the fact that the footrest 3 is flush with the seat 1 prevents the footrest 3 from protruding from the seat 1 in the folded state S1, thus helping to maintain the appearance quality of the seat 1.

[0073] Based on the above overview, the seat 1, in addition to having a frame 101, also has a foam layer and a finish covering the frame 101. In this embodiment, the receiving groove 1a is formed on the foam layer and the finish. Furthermore, the receiving groove 1a is provided on the front side of the seat 1, meaning that the footrest 3 is placed on the seat cushion of the seat 1 for use by passengers on the seat 1. It can be understood that when the footrest 3 is installed on the backrest side of the seat 1 or the back of the seat cushion of the seat 1 for use by passengers in the rear row of the seat 1, the receiving groove 1a is located on the backrest side of the seat 1 or the back of the seat cushion; the specific location depends on the actual placement of the footrest 3.

[0074] It is worth noting that, to effectively improve the overall appearance quality of seat 1, the footrest 3 is specifically designed to include a main body 301 and a decorative part 302 mounted on the main body 301. The main body 301 is mounted on seat 1 via mounting base 2. Similar to seat 1, the decorative part 302 also includes a foam layer and a finish. The foam layer and finish on the main body 301 are designed with reference to the foam layer and finish on seat 3, and will not be detailed here. Furthermore, to further improve the overall appearance quality of seat 1, the outer finish of the footrest 3 is made of the same material and color as the outer finish of seat 1.

[0075] Understandably, based on the footrest 3 including the main body 301 and the decorative part 302, to further improve the overall appearance quality of the seat 1, the footrest 3 is formed with an operating groove 3a. The operating groove 3a is formed on the decorative part 302 so that the locking part 4 can be housed within the operating groove 3a, thus preventing the locking part 4 from protruding from the outer surface of the footrest 3, thereby helping to ensure the overall appearance quality of the seat 1. It should be noted that the structure of the footrest 3 is not limited to this; as long as it can support the passenger's feet, it is acceptable, for example, the footrest 3 may only include the main body 301.

[0076] It is worth noting that, regarding the footrest structure of this embodiment, based on the above exemplary embodiments, in specific implementation, as a preferred embodiment, it is still composed of... Figures 1 to 12 As shown, it may include, for example, a mounting base 2, a footrest 3 disposed on the mounting base 2, and a locking part 4 and a first elastic part 5 disposed between the mounting base 2 and the footrest 3. The mounting base 2 is used to mount the footrest structure on the front or rear side of the seat 1. The footrest 3 is rotatable relative to the mounting base 2 and can switch between a folded state S1 and a use state S2. In the folded state S1, the footrest 3 is folded on the front or rear side of the seat 1. In the use state S2, the footrest 3 unfolds outwards from the seat 1 to support the feet. The locking part 4 is used to lock the footrest 3 in the folded state S1, and the first elastic part 5 is used to drive the footrest 3 to switch to the use state S2 after the locking part 4 is unlocked.

[0077] Among them, a limiting part 6 is provided between the footrest 3 and the mounting base 2. The limiting part 6 is used to limit the rotation angle of the footrest 3 when switching to the use state S2.

[0078] The locking part 4 includes a locking hole 4a on the mounting base 2, a locking pin 401 slidably disposed on the footrest 3, and a second elastic part 402 disposed between the locking pin 401 and the footrest 3. Under the push of the second elastic part 402, the locking pin 401 can be inserted into the locking hole 4a to lock the footrest 3 in the retracted state S1.

[0079] In the preferred embodiment of the footrest structure above, the specific configuration and arrangement of the footrest 3, locking part 4, first elastic part 5, etc. can still be referred to the descriptions in the above exemplary embodiments. Furthermore, in this preferred embodiment, the beneficial effects brought about by the design of the footrest 3, locking part 4, and first elastic part 5, etc., can also be referred to the descriptions in the above exemplary embodiments.

[0080] The footrest structure of this embodiment adopts the above design. When used to support the passenger's feet, pressing the lever 4031 causes the locking pin 401 to disengage from the locking hole 4a, thereby unlocking the footrest 3. At this time, the footrest 3 can be flipped to a state parallel to the floor under the action of the first elastic part 5, switching to the use state S2. When the footrest 3 is not in use, by flipping the footrest 3 upward, the locking pin 401 can slide into the locking hole 4a under the action of the guide slope 401c, thereby stably locking the footrest 3 to the storage state S1, preventing interference with the passenger.

[0081] Therefore, the footrest structure of this embodiment is beneficial in meeting the comfort needs of passengers of different heights and in various application scenarios, thereby improving the comfort of the seat 1. Simultaneously, the locking part 4 allows the footrest 3 to fold in front of or behind the seat 1, placing it in a stowed state S1, thus reducing its footprint in the vehicle. Furthermore, after releasing the locking part 4, the first elastic part 5 allows the footrest 3 to automatically switch from the stowed state S1 to the usable state S2, providing good ease of use.

[0082] An embodiment of the second aspect of this application provides a vehicle in which the seat 1 is provided with a footrest structure as described in the first aspect embodiment.

[0083] In this embodiment, by providing a footrest structure on the seat 1 as described in the first aspect embodiment, the comfort and functionality of the seat 1 can be improved, thereby improving the quality of the vehicle.

[0084] The above descriptions are merely some embodiments of this application and are not intended to limit this application. The technical features or structures in the foregoing different embodiments can be arbitrarily combined to form other specific technical solutions as needed. For those skilled in the art, this application can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of the claims of this application.
