Description

Technical Field

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

[0002] The comfort of vehicle seats is a crucial factor that directly affects the passenger's riding experience, making the rationality and functionality of seat design an important focus in seat design.

[0003] In related technologies, seats typically include structures such as cushions, backrests, and headrests. During the ride, passengers' legs are usually naturally hanging down or bent and placed on the vehicle floor. However, for shorter passengers, this arrangement will cause their feet to dangle in the air, which is not conducive to improving the comfort of the seat. Utility Model Content

[0004] In view of this, this application aims to provide a footrest structure and vehicle to improve seat comfort.

[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, a locking part disposed between the mounting base and the footrest, and an unlocking part throttlely connected to the locking part; The mounting base is used to mount the footrest structure on the 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 side of the seat. In the use state, the footrest unfolds outward of the seat to support the feet. The locking part has at least a first locking position and a second locking position. In the first locking position, the locking part locks the footrest in the storage state, and in the second locking position, the locking part locks the footrest in the use state. The unlocking part is used to unlock the locking part so that the footrest switches between the storage state and the use state.

[0006] Furthermore, the footrest is provided with a fixed seat, which is rotatably mounted on the mounting base via a rotating shaft; the locking part includes at least two locking grooves spaced circumferentially on the fixed seat along the rotating shaft, a locking rod slidably mounted on the mounting base, and an elastic part provided between the locking rod and the rotating shaft, wherein the locking rod can be engaged in any of the locking grooves under the action of the elastic part.

[0007] Furthermore, the unlocking part includes an unlocking plate slidably disposed on the mounting base, and the locking rod is connected to the unlocking plate; the unlocking plate is operable to slide and drive the locking rod to slide, so that the locking rod disengages from the locking groove.

[0008] Furthermore, the mounting base is provided with a first sliding groove, which extends radially along the rotating shaft; the locking rod is slidably disposed in the first sliding groove.

[0009] Furthermore, the mounting base is provided with a second sliding groove, and the unlocking plate is slidably disposed in the second sliding groove via a guide shaft; the second sliding groove is disposed on the side of the first sliding groove away from the rotating shaft, and the second sliding groove is set at an angle to the first sliding groove.

[0010] Furthermore, one end of the second groove is located on the extension line of the first groove, and the other end of the second groove extends away from the first groove.

[0011] Furthermore, the unlocking plate includes a main board and side plates disposed on two opposite sides of the main board, the locking rod and the guide shaft are disposed on the side plates, and the main board is provided with an operating rod extending away from the side plates; and / or, the fixing base includes a fixing plate and connecting plates disposed on two opposite sides of the fixing plate, the fixing plate is connected to the foot support, the connecting plate is rotatably disposed on the mounting base, and the connecting plate is an arc-shaped plate centered on the pivot, and the locking groove is disposed at the edge of the arc-shaped plate.

[0012] Furthermore, the elastic part includes a spring connected between the locking rod and the rotating shaft; and / or, the end of the footrest away from the fixed base is provided with a groove for a hand to enter and operate the footrest to rotate.

[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 the footrest to switch between a folded state and a use state. When the footrest is unfolded to the outside of the seat and in use state, it can support the passenger's feet, which is beneficial to improving the comfort of the seat. When the footrest is folded to the side of the seat and in the folded state, it can reduce the space occupied in the vehicle and help ensure the appearance quality of the seat.

[0015] Furthermore, by providing a locking mechanism with at least a first locking position and a second locking position, the stability of the footrest can be maintained whether it is in the storage or use state. Simultaneously, the unlocking mechanism facilitates switching between the storage and use states, improving the ease of use of the footrest structure.

[0016] (2) When the footrest is rotated to make the fixed base rotate around the pivot, the elastic part between the pivot and the locking rod can help the locking rod to automatically engage in the locking groove when it corresponds to the locking groove, which can improve the locking convenience of the locking part. Furthermore, by allowing the locking rod to engage in any locking groove, it is easier to switch the locking part between the first locking position and the second locking position, and it is also helpful to ensure the reliability and stability of the footrest when it is in the locked state.

[0017] (3) By setting an unlocking plate connected to the locking rod, it is easy to adjust the relative position of the locking rod and the locking groove by operating the unlocking plate, which helps to reduce the difficulty of operation and improve the convenience of unlocking. At the same time, by setting an unlocking plate so that the locking rod can be disengaged from the locking groove, it can effectively prevent the locking part from unlocking on its own, so as to keep the footrest in the preset use state or storage state.

[0018] (4) By setting the first slide groove and making the first slide groove extend radially along the rotating shaft, it is beneficial to make the locking rod slide in the first slide groove, accurately correspond to the locking groove and engage in the locking groove, which is beneficial to improve the locking smoothness and reliability of the locking part. Furthermore, setting the first slide groove to extend radially along the rotating shaft is beneficial to make the elastic part apply force between the rotating shaft and the locking rod.

[0019] (5) By setting the first slide groove and the second slide groove at an angle, it is beneficial to apply a force other than that along the extension direction of the first slide groove to the unlocking plate, thereby driving the locking rod to slide along the extension direction of the first slide groove, which helps to reduce the difficulty of operation and improve the unlocking convenience of the unlocking part.

[0020] (6) By setting one end of the second slide groove to be located on the extension line of the first slide groove, the guide shaft, locking rod, and rotating shaft are arranged along the extension direction of the first slide groove. This ensures that when the locking rod is engaged in the lock groove, there is an operating space between the unlocking rod and the seat, so that the unlocking rod can unlock the locking part when it moves within this operating space. Furthermore, this helps to ensure the overall compactness of the mounting base, locking part, and unlocking part.

[0021] (7) By including two oppositely arranged side plates in the unlocking plate, it is easier to apply a uniform force to the locking rod through the main plate, which helps to ensure the smooth sliding of the locking rod. In addition, by setting an operating lever, it is possible to unlock the locking part by operating the unlocking plate in different positions, which helps to improve the convenience of use.

[0022] By designing the connecting plate as an arc shape, the locking rod can slide along the edge of the connecting plate under the action of the elastic part, thus ensuring the smoothness of the sliding rod's movement. Furthermore, it facilitates the locking rod's engagement into the locking groove.

[0023] (8) By setting the elastic part to include a spring, the elastic part can be assembled between the rotating shaft and the locking rod, which is beneficial to the design and implementation of the elastic part.

[0024] By designing grooves to allow the hand to enter the recess, a force-applying space is created to exert force on the footrest, which improves ease of operation.

[0025] (9) By setting the footrest to be stored in the receiving slot, the footrest is flush with the seat, which helps to reduce the space occupied by the footrest and improves the overall appearance quality of the seat.

[0026] Another object of this application is to provide a vehicle in which the seat is provided with the footrest structure described above.

[0027] The vehicle described in this application, by providing the footrest structure as described above on the seat, can support the passenger's feet, which is especially beneficial for passengers who are shorter or those sitting in child seats, thus improving the comfort of the seat.

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.

[0033] 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.

[0034] 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.

[0035] 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 and improve the comfort of the seat 1. The footrest structure also has a folded state S1 through innovative design. In this state, the footrest structure is folded and stored on the side of the seat, which helps to reduce the space occupied in the vehicle and helps to ensure the appearance quality of the seat 1.

[0036] In related technologies, seat 1 typically includes a cushion, backrest, and headrest. During the ride, the passenger's legs are usually naturally hanging down or bent and placed on the vehicle floor. However, for shorter passengers or passengers in child seats 1, the cushion is a certain distance from the vehicle floor, which makes it easy for the passenger's feet to dangle, which is not conducive to improving the comfort of seat 1.

[0037] In view of this, in order to overcome the shortcomings of related technologies, the footrest structure of this embodiment combines... Figures 1 to 6As shown, the overall design includes a mounting base 2, a footrest 3 mounted on the mounting base 2, a locking part 4 located between the mounting base 2 and the footrest 3, and an unlocking part 5 that is kinetically connected to the locking part 4. The mounting base 2 is used to mount the footrest structure on the 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 side of the seat 1. In the usage state S2, the footrest 3 unfolds outwards from the seat 1 to support the feet.

[0038] The locking part 4 has at least a first locking position T1 and a second locking position T2. ​​In the first locking position T1, the locking part 4 locks the footrest 3 in a stored state S1. In the second locking position T2, the locking part 4 locks the footrest 3 in a used state S2. The unlocking part 5 is used to unlock the locking part 4 so that the footrest 3 switches between the stored state S1 and the used state S2.

[0039] Therefore, by enabling the footrest 3 to switch between a stowed state S1 and a used state S2, when the footrest 3 is unfolded to the outside of the seat 1 and in the used state S2, it can support the passenger's feet, which helps to improve the comfort of the seat 1. When the footrest 3 is folded to the side of the seat 1 in the stowed state S1, it can reduce the space occupied in the vehicle and help to maintain the appearance quality of the seat 1.

[0040] Furthermore, by providing the locking part 4 with at least a first locking position T1 and a second locking position T2, it is beneficial to maintain the stability of the footrest 3 when it is in the storage state S1 or the use state S2. At the same time, providing the unlocking part 5 facilitates the switching of the footrest 3 between the storage state S1 and the use state S2, which helps to improve the ease of use of the footrest structure.

[0041] Based on the above overview, it is worth noting that the mounting base 2 is used to install the footrest structure on the side of the seat 1. Specifically, the footrest structure can be installed on the front side of the seat 1 or on the rear side of the seat 1 via the mounting base 2.

[0042] In detail, when the footrest structure is installed on the front side of seat 1, it means that the footrest 3 is installed on the front side of the seat cushion of seat 1 in the normal fore-aft direction to support the feet of the passenger on seat 1. When the footrest structure is installed on the rear side of seat 1, it means that the footrest 3 is installed on the rear side of seat 1 in the fore-aft direction of the entire vehicle. Specifically, it can be installed on the rear side of the seat cushion of seat 1 or on the backrest of seat 1 for use by the rear passengers of seat 1.

[0043] In this embodiment, taking the footrest structure installed on the front side of seat 1 as an example, in the usage state S2, the footrest 3 unfolds outwards from the seat 1, meaning that the footrest 3 unfolds forward along the front-to-back direction of the vehicle so that the footrest 3 is parallel to the vehicle floor, thus supporting the passenger's feet. Of course, it can be understood that when the footrest structure is installed on the rear side of seat 1, the footrest 3 unfolds outwards from the seat 1, meaning that it unfolds backwards along the front-to-back direction of the vehicle, and similarly makes the footrest 3 parallel to the vehicle floor.

[0044] It is worth noting that, as an optional implementation of the mounting base 2, combined with Figures 2 to 6 As shown, to facilitate the connection between the mounting base 2 and the footrest 3 and the seat 1, in this embodiment, the mounting base 2 includes a first part 201 and a second part 202. The first part 201 is used to connect the second part 202 to the frame 101 of the seat 1. The second part 202 has an outwardly protruding portion 203, which connects to the footrest 3. Preferably, in this embodiment, the first part 201 is fixed to the frame 101, for example, by welding the first part 201 to the frame 101, to ensure the reliable connection between the first part 201 and the seat 1. The second part 202 is detachably connected to the first part 201, for example, by using threaded parts to connect the first part 201 and the second part 202. This arrangement allows the footrest structure to be assembled onto the seat 1 after the seat 1 is fully formed, which optimizes the assembly process and facilitates the later maintenance of the footrest 3.

[0045] In some of the exemplary implementations, combined with Figure 5 and Figure 6 As shown, the footrest 3 is provided with a fixed seat 6, which is rotatably mounted on the mounting base 2 via a rotating shaft 7; the locking part 4 includes at least two locking grooves 4a spaced apart on the fixed seat 6 along the circumference of the rotating shaft 7, a locking rod 401 slidably mounted on the mounting base 2, and an elastic part 402 provided between the locking rod 401 and the rotating shaft 7, wherein the locking rod 401 can be engaged in any locking groove 4a under the action of the elastic part 402.

[0046] Therefore, when the footrest 3 is rotated to make the fixed base 6 rotate around the pivot 7, the elastic part 402 provided between the pivot 7 and the locking rod 401 facilitates the locking rod 401 to automatically engage with the locking groove 4a when it corresponds to the locking groove 4a, thereby improving the locking convenience of the locking part 4. Furthermore, by allowing the locking rod 401 to engage with either locking groove 4a, it is easier for the locking part 4 to switch between the first locking position T1 and the second locking position T2, and it helps to ensure the reliability and stability of the footrest 3 when it is in the locked state.

[0047] Based on the above overview, given that the mounting base 2 has a protruding portion 203, to achieve the rotatable connection between the fixed base 6 and the mounting base 2 via the rotating shaft 7, it can be understood that the protruding portion 203 and the fixed base 6 have an overlapping area that always overlaps. The rotating shaft 7 passes through this overlapping area, allowing the footrest 3 to switch between a folded state S1 and a usage state S2. It can also be understood that, given the protruding portion 203 of the mounting base 2, a locking rod 401 passes through the protruding portion 203. Furthermore, two sets of protruding portions 203 are provided along the axial direction of the locking rod 401.

[0048] It is understandable that the locking groove 4a is provided on the fixed seat 6 along the circumference of the rotating shaft 7, which means that the distance between the rotating shaft 7 and the two locking grooves 4a is the same. This arrangement is such that when the fixed seat 6 rotates around the rotating shaft 7, the locking rod 401 can be inserted into either locking groove 4a, thereby allowing the locking part 4 to be locked in the first locking position T1 or the second locking position T2.

[0049] It is worth noting that, in specific implementation, the locking rod 401 is cylindrical. To effectively ensure the stability of the locking rod 401 when it is engaged in the locking groove 4a, in this embodiment, the locking groove 4a is preferably an arc-shaped groove, so that the locking rod 401 fits snugly against the locking groove 4a. Furthermore, the depth of the locking groove 4a is set to be the same as the radius of the locking rod 401. This design not only ensures the stability of the locking rod 401 when it is engaged in the locking groove 4a, but also facilitates the unlocking part 5 to disengage the locking rod 401 from the locking groove 4a.

[0050] In some of the exemplary implementations, combined with Figure 5 and Figure 6 As shown, the unlocking part 5 includes an unlocking plate 501 slidably disposed on the mounting base 2, and a locking rod 401 connected to the unlocking plate 501; the unlocking plate 501 can be slidable when operated, and drives the locking rod 401 to slide, so that the locking rod 401 disengages from the locking groove 4a.

[0051] Therefore, by connecting the unlocking plate 501 to the locking rod 401, it is convenient to adjust the relative position of the locking rod 401 and the locking groove 4a by operating the unlocking plate 501, which helps to reduce the difficulty of operation and improve the convenience of unlocking. At the same time, by setting the unlocking plate 501 so that the locking rod 401 can disengage from the locking groove 4a, it can effectively prevent the locking part 4 from unlocking on its own, so as to keep the footrest 3 in the preset use state S2 or storage state S1.

[0052] It is worth noting that, in order to enable the locking rod 401 to disengage from the locking groove 4a by operating the unlocking plate 501, in this embodiment, the unlocking plate 501 is fixedly connected to the locking rod 401, and the unlocking plate 501 is slidably clamped between the two protruding portions 203.

[0053] In some of the exemplary implementations, combined with Figure 5 and Figure 6 As shown, the mounting base 2 is provided with a first sliding groove 2a, which extends radially along the rotating shaft 7; the locking rod 401 is slidably disposed in the first sliding groove 2a.

[0054] Therefore, by providing the first slide groove 2a and extending it radially along the rotating shaft 7, it is beneficial for the locking rod 401 to slide within the first slide groove 2a and accurately correspond to and engage with the locking groove 4a, thereby improving the smoothness and reliability of the locking part 4. Furthermore, by providing the first slide groove 2a to extend radially along the rotating shaft 7, it is beneficial for the elastic part 402 to apply force between the rotating shaft 7 and the locking rod 401.

[0055] It is worth noting that, as an optional method of opening the first slide groove 2a, in this embodiment, the first slide groove 2a is set on the protruding portion 203, and the first slide groove 2a is opened approximately along the vertical direction of the entire vehicle. With this configuration, the locking rod 401 can be slid along the first slide groove 2a by operating the unlocking plate 501, thereby disengaging from the locking groove 4a.

[0056] In some of the exemplary implementations, combined with Figures 5 to 7 As shown, the mounting base 2 is provided with a second slide groove 2b, and the unlocking plate 501 is slidably disposed in the second slide groove 2b through the guide shaft 502; the second slide groove 2b is disposed on the side of the first slide groove 2a away from the rotating shaft 7, and the second slide groove 2b is set at an angle to the first slide groove 2a.

[0057] Therefore, by setting the first slide groove 2a and the second slide groove 2b at an angle, it is beneficial to apply a force other than that along the extension direction of the first slide groove 2a to the unlocking plate 501, thereby driving the locking rod 401 to slide along the extension direction of the first slide groove 2a, which helps to reduce the difficulty of operation and improve the unlocking convenience of the unlocking part 5.

[0058] It is understood that the unlocking plate 501 is slidably clamped between the two protruding portions 203 via the guide shaft 502 and the second sliding groove 2b. In specific implementation, similar to the first sliding groove 2a, the second sliding groove 2b is also formed on the protruding portion 203. The guide shaft 502 is fixed to the unlocking plate 501 and slidably inserted into the second sliding groove 2b.

[0059] It is worth noting that the second slide 2b is located at the end of the first slide 2a away from the rotating shaft 7. Based on the first slide 2a being opened roughly along the vertical direction of the whole vehicle, in this embodiment, the rotating shaft 7 is located below the first slide 2a, while the second slide 2b is located above the first slide 2a. This arrangement makes the unlocking plate 501 located entirely above the rotating shaft 7, which facilitates the operation of the unlocking plate 501.

[0060] It is also worth noting that the second slide groove 2b is set at an angle to the first slide groove 2a. Specifically, the second slide groove 2b is inclined, meaning that as it extends upward along the vertical direction of the vehicle, it gradually tilts towards the side of the seat 1 or away from the seat 1 to form an inclined second slide groove 2b. This arrangement allows the guide shaft 502 to slide along the second slide groove 2b when the unlocking plate 501 is subjected to a pressing or pulling force. At this time, as the unlocking plate 501 moves, a portion of the upward pulling force can be distributed and acted on the locking rod 401, causing the locking rod 401 to disengage from the locking groove 4a.

[0061] In this specific embodiment, the second slide groove 2b extends upward along the vehicle direction while gradually tilting towards the side closer to the seat 1. With this configuration, pressing or pulling the unlocking plate 501 towards the side closer to the seat 1 allows the locking rod 401 to disengage from the locking groove 4a, thus unlocking the locking part 4. Specifically, the angle between the first slide groove 2a and the second slide groove 2b can be set to 135°. Of course, the angle between the first slide groove 2a and the second slide groove 2b can be any other angle, so that as the unlocking plate 501 moves, a portion of the upward pulling force is distributed and applied to the locking rod 401, causing the locking rod 401 to disengage from the locking groove 4a.

[0062] In some of the exemplary implementations, combined with Figure 7 As shown, one end of the second groove 2b is located on the extension line of the first groove 2a, and the other end of the second groove 2b extends away from the first groove 2a.

[0063] Therefore, by setting one end of the second slide groove 2b to be located on the extension line of the first slide groove 2a, the guide shaft 502, the locking rod 401, and the rotating shaft 7 are arranged along the extension direction of the first slide groove 2a. This ensures that when the locking rod 401 is engaged in the locking groove 4a, there is an operating space between the unlocking rod 401 and the second part 202, allowing the unlocking rod 401 to unlock the locking part 4 when it moves within this operating space. Furthermore, this helps to ensure the compactness of the overall arrangement of the mounting base 2, the locking part 4, and the unlocking part 5.

[0064] In some of the exemplary implementations, combined with Figure 2 , Figure 3 , Figure 5 and Figure 10 As shown, the unlocking plate 501 includes a main board 5011 and side plates 5012 disposed on two opposite sides of the main board 5011. The locking rod 401 and the guide shaft 502 are disposed on the side plates 5012. The main board 5011 is provided with an operating rod 503 extending to the side away from the side plates 5012.

[0065] Therefore, by including two opposing side plates 5012 in the unlocking plate 501, it is easier to apply a uniform force to the locking rod 401 through the main plate 5011, which helps to ensure the smooth sliding of the locking rod 401. Furthermore, by providing the operating lever 503, it is possible to unlock the locking part 4 by operating the unlocking plate 501 in different positions, which improves the ease of use.

[0066] Based on the above overview, it can be understood that both the rotating shaft 7 and the guide shaft 502 are connected to the side plate 5012. In specific implementation, to effectively improve the stability of the footrest 3 on the seat 1, in this embodiment, mounting seats 2 are provided at both ends of the footrest 3 along its length. Each mounting seat 2 corresponds to a locking part 4 and an unlocking part 5. Furthermore, to facilitate the simultaneous unlocking of multiple locking parts 4, it is preferable to provide a crossbar at the end of each operating lever 503 facing away from the main board, connecting two operating levers 503. With this configuration, controlling the crossbar allows simultaneous control of two operating levers 503. Of course, it can be understood that when there are two or more mounting seats 2 along the length of the footrest 3, the crossbar is connected to multiple operating levers 503 to achieve simultaneous unlocking of multiple locking parts 4, which helps improve operational convenience.

[0067] In some of the exemplary implementations, combined with Figures 5 to 8 As shown, the fixed base 6 includes a fixed plate 601 and a connecting plate 602 disposed on two opposite sides of the fixed plate 601. The fixed plate 601 is connected to the foot support 3. The connecting plate 602 is rotatably disposed on the mounting base 2. The connecting plate 602 is an arc-shaped plate centered on the rotating shaft 7. The locking groove 4a is disposed at the edge of the arc-shaped plate.

[0068] Therefore, by setting the connecting plate 602 as an arc-shaped plate, it is beneficial for the locking rod 401 to slide along the edge of the connecting plate 602 under the action of the elastic part 402, thus ensuring the smoothness of the sliding rod. Furthermore, it facilitates the locking rod 401 to engage with the locking groove 4a.

[0069] It is worth noting that, in specific implementation, the connecting plate 602 is set perpendicular to the rotating shaft 7, so that when the connecting plate 602 rotates around the rotating shaft 7, the locking rod 401 can be engaged into the locking groove 4a. It can be understood that the connecting plate 602 is an arc-shaped plate centered on the rotating shaft 7, specifically meaning that the center of the arc corresponding to the arc contour of the arc-shaped plate is located on the axis of the rotating shaft 7.

[0070] It is understandable that, as a specific implementation of the two locking grooves 4a, in this embodiment, it is preferable to set the angle between the two lines connecting the center of the two locking grooves 4a and the axis of the rotating shaft 7 to be 90°, and to position one of the locking grooves 4a in the middle of the arc-shaped contour of the connecting plate 602. Of course, it is understandable that the angle between the two lines connecting the center of the two locking grooves 4a and the axis of the rotating shaft 7 can be other angles, so that when the locking part 4 switches between the first locking position T1 and the second locking position T2, the footrest 3 can switch between the use state S2 and the storage state S1.

[0071] In some of the exemplary implementations, combined with Figure 5 As shown, the elastic part 402 includes a spring connecting the locking rod 401 and the rotating shaft 7. By including a spring in the elastic part 402, it is easier to assemble the elastic part 402 between the rotating shaft 7 and the locking rod 401, which facilitates the design and implementation of the elastic part 402. In a specific implementation, it is preferable to position the spring hook at the midpoint of the length direction of the rotating shaft 7.

[0072] In some of the exemplary implementations, combined with Figure 1 As shown, the footrest 3 has a groove 3a at the end away from the fixed base 6. The groove 3a is for the hand to enter and operate the footrest 3 to rotate.

[0073] Therefore, by setting the groove 3a to facilitate the hand entering the groove, a force application space is formed to apply force to the footrest 3, which helps to improve the ease of operation.

[0074] 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.

[0075] Therefore, by storing the footrest 3 within the receiving slot 1a, making the footrest 3 flush with the seat 1, the space occupied by the footrest 3 is reduced, which helps to improve the overall appearance quality of the seat 1. At the same time, by storing the footrest 3 within the receiving slot 1a, the footrest 3 is prevented from protruding onto the outer surface of the seat, thus avoiding interference between the footrest 3 and the passenger's legs, which helps to ensure the comfort of the seat 1.

[0076] It is worth noting that, in specific implementation, the footrest 3 includes a base plate 301 and a decorative layer 302 disposed on the outer side of the base plate 301, and a groove 3a is formed by the base plate 301 protruding towards the decorative layer 302. Furthermore, to effectively improve the overall appearance quality of the footrest 3, the outer surface of the decorative layer 302 is made complete and flush with the outer surface of the seat 1, and the decorative layer 302 is made to be identical to the seat 1 in terms of color, material, etc., thus improving the overall appearance quality of the seat 1.

[0077] Based on the above overview, it is understandable that, combined with Figure 2 and Figure 9 As shown, in order to facilitate the application of force to the footrest 3 through the groove 3a, when the footrest 3 is in the storage state S1, that is, when the footrest 3 is housed in the receiving groove 1a, an operation opening 1b is formed between the footrest 3 and the seat 1. The operation opening 1b corresponds to the groove 3a, so that the hand can be inserted into the groove 3a through the operation opening 1b.

[0078] Based on this, a crossbar connected to the operating lever 503 is provided with an operating port 1b, so that force can be applied to the operating lever 503 through the operating port 1b, thereby unlocking the locking part 4 through the unlocking part 5. This facilitates the switching of the locking part 4 between the first locking position T1 and the second locking position T2, ultimately allowing the footrest 3 to switch between the use state S2 and the storage state S1. It can also be understood that when the footrest 3 is stored in the receiving groove 1a, there is a certain operating space between the footrest 3 and the side wall of the receiving groove 1a, allowing the force to be transmitted to the unlocking plate 501 through the operating lever 503, thereby unlocking the locking part 4 through the unlocking part 5.

[0079] Preferably, the crossbar connected to the operating lever 503 also has an extension portion 5031 that protrudes outward into the operating port 1b. By providing the extension portion 5031, the hand does not need to be fully inserted into the operating port 1b to apply force to the operating lever 503, which helps to improve the convenience of operation.

[0080] 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 10 As shown, it includes, for example, a mounting base 2, a footrest 3 mounted on the mounting base 2, a locking part 4 located between the mounting base 2 and the footrest 3, and an unlocking part 5 pulsatorically connected to the locking part 4. The mounting base 2 is used to mount the footrest structure on the 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 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 has at least a first locking position T1 and a second locking position T2. ​​In the first locking position T1, the locking part 4 locks the footrest 3 in a stored state S1. In the second locking position T2, the locking part 4 locks the footrest 3 in a used state S2. The unlocking part 5 is used to unlock the locking part 4 so that the footrest 3 switches between the stored state S1 and the used state S2.

[0081] The seat 1 has a receiving groove 1a on its front side, and the footrest 3 in the storage state S1 is housed in the receiving groove 1a, with the front side of the footrest 3 flush with the front side of the seat 1.

[0082] In the preferred embodiment of the above footrest structure, the specific settings and arrangements of the mounting base 2, locking part 4, unlocking 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 mounting base 2, locking part 4, and unlocking part 5, etc., can also be referred to the descriptions in the above exemplary embodiments.

[0083] The footrest structure of this embodiment adopts the above design. When foot support is required, the operating lever 503 can be pressed inward or pulled upward to transmit force to the unlocking plate 501, causing the guide shaft 502 to slide along the second slide groove 2b and the rotating shaft 7 to slide along the first slide groove 2a. This causes the locking lever 401 to disengage from the locking groove 4a, rotating the footrest 3 to a horizontal position. At this time, the locking lever 401 engages in another locking groove 4a, switching the footrest 3 to the use state S2. When switching to the storage mode, the operating lever 503 is pressed or pulled to disengage the locking lever 401 from the locking groove 4a. The footrest 3 is then flipped over to be stored in the receiving groove 1a. When the locking lever 401 engages in another locking groove 4a, the footrest 3 is switched to the storage state S1.

[0084] By allowing the footrest 3 to switch between a stowed state S1 and a usable state S2, when the footrest 3 is unfolded outwards from the seat 1 and in the usable state S2, it can support the passenger's feet, thus improving the comfort of the seat 1. When the footrest 3 is folded to the side of the seat 1 in the stowed state S1, it reduces the space occupied in the vehicle interior and helps maintain the appearance quality of the seat 1. Furthermore, by providing the locking part 4 with at least a first locking position T1 and a second locking position T2, the stability of the footrest 3 in both the stowed state S1 and the usable state S2 can be maintained. At the same time, the unlocking part 5 facilitates the switching of the footrest 3 between the stowed state S1 and the usable state S2, thus improving the ease of use of the footrest structure.

[0085] 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.

[0086] In this embodiment, the vehicle provides foot support for passengers by providing a footrest structure on the seat 1 as described in the first aspect embodiment. This is particularly beneficial for improving the comfort of passengers who are shorter or those sitting in child seats 1.

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.
