Abstract
Description
Technical Field
[0001] This application relates to the field of vehicle interior technology, and in particular to a footrest assembly and a vehicle. Background Technology
[0002] Vehicle ride comfort is a crucial factor affecting the driving experience. Since seats are in direct contact with passengers, their design comfort and rationality become key concerns.
[0003] In related technologies, seat design often focuses on functions such as torso support and posture adjustment, which makes the seats less adaptable to individual differences among people of different heights and makes it difficult to adapt to diverse application scenarios, thus hindering the improvement of seat comfort. Utility Model Content
[0004] In view of this, this application aims to provide a footrest assembly to improve seat comfort.
[0005] To achieve the above objectives, the technical solution of this application is implemented as follows: A footrest assembly, adapted to be mounted on a seat, includes a mounting bracket slidably disposed on the side of the seat in the fore-and-aft direction of the seat, a footrest rotatably disposed on the mounting bracket, and a locking part disposed between the mounting bracket and the seat; The locking part can lock the mounting bracket and the footrest to the side of the seat. After unlocking, the mounting bracket can slide to the outside of the seat and switch the footrest between a storage state and a use state. In the stowed state, the footrest is folded onto the mounting bracket; in the use state, the footrest is flipped over to the outside of the seat.
[0006] Furthermore, the footrest includes a footrest body rotatably mounted on the mounting bracket at one end, a support frame rotatably mounted on the other end of the footrest body, and a limiting portion disposed between the support frame and the footrest body; the support frame can switch between a first state and a second state, in the first state the support frame is folded onto the footrest body, in the second state the support frame is supported below the footrest body, and the limiting portion can restrict the rotation angle of the support frame.
[0007] Furthermore, the footrest body is provided with a pivot and a rotating protrusion at the end of the pivot, the support frame is provided with a shaft hole, and the rotating protrusion is rotatably disposed in the shaft hole; the limiting part includes a limiting protrusion protruding into the shaft hole and a mating surface provided on the outer wall of the rotating protrusion, the limiting protrusion abutting against the mating surface, which can limit the rotation angle of the support frame.
[0008] Furthermore, the support frame has a support protrusion projecting toward the side away from the shaft hole, the support protrusion being used to abut against an external carrier; in the second state, the support protrusion is biased toward the side of the shaft hole away from the mounting frame.
[0009] Furthermore, the mounting bracket includes a frame body and a slider protruding outward from the frame body; the frame body is annular and has a receiving hole, and in the retracted state, the footrest body and the support frame are located in the receiving hole, and the mounting bracket is slidably mounted on the seat by the slider.
[0010] Furthermore, one of the support frame and the frame body is provided with a limiting groove, and the other of the two is provided with a limiting block; the limiting block can be inserted into the limiting groove to limit the rotation angle of the footrest when switching from the use state to the storage state.
[0011] Furthermore, a locking part is provided between the mounting bracket and the footrest, which can lock the footrest in the stored state.
[0012] Furthermore, the locking part includes a locking hole on the footrest, a locking pin slidably disposed on the mounting bracket, and an elastic part disposed between the locking pin and the mounting bracket; under the action of the elastic part, the locking pin is inserted into the locking hole to restrict the footrest from rotating relative to the mounting bracket.
[0013] Furthermore, the locking part includes a retaining ring disposed on the seat and a retaining block disposed on the mounting bracket; the retaining block can be engaged in the retaining ring to lock the mounting bracket to the side of the seat.
[0014] Compared with related technologies, this application has the following advantages: (1) The footrest assembly described in this application allows the footrest to switch between a use state and a storage state. When the footrest is not in use, it is locked to the side of the seat to prevent interference with the passenger and reduce space occupation. When the footrest is in use, it can support the passenger's feet, thereby meeting the needs of people of different heights, especially short passengers or children, for seat comfort and improving the seating comfort of the seat.
[0015] Meanwhile, when the footrest is in the folded state, the locking mechanism effectively prevents the mounting bracket from moving unnecessarily, thus ensuring that the footrest remains stably folded.
[0016] (2) By having the support frame in a first state, it is easy to fold the support frame onto the footrest body, thereby reducing the space occupied by the footrest when stored. Furthermore, by having the support frame in a second state, supporting the support frame under the footrest body, it is beneficial to improve and ensure the load-bearing capacity of the footrest body. At the same time, the limiting part can effectively limit and maintain the rotation angle of the support frame, effectively preventing excessive rotation of the support frame, thereby helping to ensure the reliability of the footrest in the second state.
[0017] (3) By setting a rotating protrusion inside the shaft hole, it is possible to make the support frame and the footrest body rotate relative to each other without jamming. At the same time, by setting a mating surface to abut against the limiting protrusion to limit the rotation angle of the support frame, without the need to set other limiting components, the space occupied by the limiting part can be effectively reduced, making the footrest easier to design and implement.
[0018] (4) By setting the support protrusion to be biased on the side of the shaft hole away from the mounting bracket, when the support protrusion abuts against the external carrier, the reverse force of the external carrier on the support protrusion can apply torque to the support frame, and the direction of the torque is opposite to the direction of the force required to fold the support frame. This setting can prevent the support frame from folding on its own when stepping on the footrest body, which is conducive to further ensuring the support stability of the footrest.
[0019] (5) By enabling the footrest body and support frame to be stored in the receiving hole, the compactness of the footrest in the first state can be improved, thereby further reducing the space occupied by storing the footrest.
[0020] (6) By setting limit blocks and limit grooves, when the footrest is switched from the use state to the storage state, the support frame can be effectively prevented from rotating excessively, which is conducive to the support frame being stored in the receiving hole.
[0021] (7) By setting a locking part, the footrest can be effectively prevented from accidentally flipping over, which helps the footrest assembly to be stably kept in the storage state.
[0022] (8) By providing a locking part that includes an elastic part, when locking the corresponding keyhole, the locking pin can be inserted into the keyhole by the elastic part, which improves the ease of use of the locking part. Furthermore, the elastic part can keep the locking pin in the keyhole, thus ensuring the stability of the foot support and the mounting bracket when locked.
[0023] (9) By setting a locking part including a retaining ring and a retaining block, the mounting bracket can be locked to the side of the seat, and the mounting bracket can be easily unlocked by adopting a retaining locking structure, which is conducive to improving the convenience of use.
[0024] Another object of this application is to provide a vehicle in which the seat is provided with the footrest assembly as described above.
[0025] The vehicle described in this application, by providing the footrest assembly as described above on the seat, can better meet the needs of people of different heights for seat comfort, thereby improving riding comfort. 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.

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 assembly suitable for mounting on a seat 1, which can support the feet of passengers. Furthermore, through innovative design, the footrest assembly can switch between a folded state S1 and a usage state S2 for different user groups, thereby improving the functionality of the seat 1.
[0034] In related technologies, the design of car seats focuses on functions such as torso support and posture adjustment. Since the seat cushion of seat 1 is a certain height from the vehicle floor, it is easy for shorter passengers or passengers sitting in child seats to have their feet dangling in the air. This makes seat 1 unsuitable for adapting to individual differences among people of different heights, and also makes it difficult for seat 1 to adapt to diverse application scenarios, which is not conducive to improving the comfort of seat 1.
[0035] In view of this, in order to overcome the shortcomings of the related technology, the footrest assembly of this embodiment combines... Figures 1 to 6 ,as well as Figure 14 As shown, the overall design includes a mounting bracket 2 that slides along the front-back direction of the seat 1 on the side of the seat 1, a footrest 3 that rotates on the mounting bracket 2, and a locking part 4 that is located between the mounting bracket 2 and the seat 1.
[0036] The locking part 4 can lock the mounting bracket 2 and the footrest 3 to the side of the seat 1. After unlocking, the mounting bracket 2 can slide to the outside of the seat 1, and the footrest 3 can switch between a storage state S1 and a use state S2. In the storage state S1, the footrest 3 is folded on the mounting bracket 2. In the use state S2, the footrest 3 is flipped to the outside of the seat 1.
[0037] Based on the above description, by enabling the footrest 3 to switch between the usage state S2 and the storage state S1, when the footrest 3 is not in use, it is locked to the side of the seat 1 to prevent interference with the passenger and reduce space occupation. When the footrest 3 is in the usage state S2, it can support the passenger's feet, thereby meeting the comfort needs of people of different heights, especially shorter passengers or children, and improving the seating comfort of the seat 1.
[0038] Meanwhile, when the footrest 3 is in the folded state S1, the locking part 4 can effectively prevent the mounting bracket 2 from moving arbitrarily in the front-back direction of the seat 1, so that the footrest 3 can be stably kept in the folded state S1.
[0039] Based on the above overall introduction, specifically, combined with Figures 1 to 3 As shown, the mounting bracket 2 is slidably disposed on the side of the seat 1 along the front-to-back direction of the seat 1. This means that the mounting bracket 2 can slide along the front-to-back direction of the entire vehicle, and along the left-to-right direction of the entire vehicle, the mounting bracket 2 can be disposed on the left or right side of the seat 1. In this embodiment, the mounting bracket 2 is disposed on the right side of the seat 1 as an example for explanation.
[0040] To effectively ensure both the comfort and aesthetic quality of the seat 1, a receiving cavity 1a can be formed on the right side of the seat 1, with the opening of the receiving cavity 1a facing the front of the seat 1. The mounting bracket 2 can slide along the front-back direction of the seat 1 and be stored in the receiving cavity 1a. This arrangement helps to ensure the aesthetic quality of the seat 1. Preferably, to facilitate pushing and pulling the mounting bracket 2, in this embodiment, a pull knob 203 is fixedly connected to the front side of the mounting bracket 2, which allows the mounting bracket 2 to be easily pulled forward.
[0041] Furthermore, in specific implementation, improvements can be made to the conventional seat technology. Specifically, a trim panel 101 can be provided on the outer side of the side panel of the seat 1, with the opening located on the front side of the trim panel 101. In this case, the accommodating cavity 1a is formed by the trim panel 101 and the side panel of the seat. It should be noted that, in order to improve the overall aesthetics of the seat 1 when the footrest assembly is in the folded state S1, zippers can be provided on both sides of the opening of the trim panel 101. Thus, when the footrest structure is stored in the accommodating cavity 1a, the footrest assembly can be concealed by closing the zippers, which helps to maintain the overall appearance of the seat 1.
[0042] Of course, for ease of application, in specific implementation, the trim panel 101 may not be provided, and the footrest assembly may be directly exposed on the outside of the side panel of the seat 1. In this case, when viewed from the front and rear sides of the seat 1, the footrest structure is hidden in the side of the seat, which also makes the seat more aesthetically pleasing.
[0043] Therefore, it is worth noting that the unlocked mounting bracket 2 can slide outwards from the seat 1. This means that after the locking part 4 releases the locking of the mounting bracket 2, the mounting bracket 2 can slide forward along the front-rear direction of the seat 1 and move to the outside of the receiving cavity 1a, so that the mounting bracket 2 is located at the side front of the seat 1, thereby facilitating the flipping of the footrest 3. Based on this, it can be understood that when the footrest 3 changes from the storage state S1 to the use state S2, causing the footrest 3 to flip to the outside of the seat 1, it means that with the mounting bracket 2 located at the side front of the seat 1, the footrest 3 is reversed, so that the footrest 3 is located directly in front of the seat 1, thereby facilitating support for the passenger's feet.
[0044] In some of the exemplary implementations, combined with Figures 2 to 8 As shown, the footrest 3 includes a footrest body 301 rotatably mounted on the mounting bracket 2 at one end, a support frame 302 rotatably mounted on the other end of the footrest body 301, and a limiting part 303 disposed between the support frame 302 and the footrest body 301. The support frame 302 can switch between a first state T1 and a second state T2. In the first state T1, the support frame 302 is folded onto the footrest body 301. In the second state T2, the support frame 302 is supported under the footrest body 301. The limiting part 303 can limit the rotation angle of the support frame 302.
[0045] Therefore, by having the support frame 302 in a first state T1, it is easy to fold the support frame 302 onto the footrest body 301, thereby reducing the space occupied by the footrest 3 when stored. Furthermore, by having the support frame 302 in a second state T2, supporting the support frame 302 under the footrest body 301, the load-bearing capacity of the footrest body 301 is improved and guaranteed. At the same time, the limiting part 303 effectively restricts and maintains the rotation angle of the support frame 302, effectively preventing excessive rotation of the support frame 302, thus ensuring the reliability of the footrest 3 in the second state T2.
[0046] It is worth noting that, in specific implementation, it should be combined with Figure 5As shown, in this embodiment, the footrest body 301 is a long strip-shaped plate structure, and the rotatable connection position between the footrest body 301 and the mounting frame 2 is located at the bottom of the mounting frame 2. Meanwhile, the support frame 302 is generally an n-shaped columnar structure. When the support frame 302 is folded onto the footrest body 301, it can be fitted onto the other end of the footrest body 301 along its length, thus reducing the space occupied by the footrest 3 in the first state T1. Furthermore, to facilitate the flipping of the footrest body 301, a clearance groove 301a is formed between the footrest body 301 and the support frame 302, allowing the passenger's hand to reach into the clearance groove 301a to flip the footrest body 301.
[0047] Based on the above settings, when the support frame 302 is in the second state T2, the support frame 302 and the mounting frame 2 are located at both ends of the foot support body 301 in the length direction, and the rotation angle of the support frame 302 is limited by the limiting part 303 to achieve stable support for the foot support body 301.
[0048] Of course, it is understandable that, as an optional implementation of the footrest 3, the footrest may also consist only of the footrest body 301. In this case, a limiting block can be provided at the bottom of the mounting bracket 2. This limiting block can support the footrest body 301 in use, thereby restricting the downward rotation of the footrest body 301. This structure can also keep the footrest body 301 in use. However, this structure only supports one end of the footrest body 301, and because the cantilever of the footrest body 301 is large, the stability of the footrest body 301 is poor. Therefore, in this embodiment, the footrest 3 is preferably configured to include the footrest body 301, the support frame 302, and the limiting part 303.
[0049] In some of the exemplary implementations, combined with Figures 5 to 12 As shown, the footrest body 301 is provided with a rotating shaft 5 and a rotating protrusion 501 at the end of the rotating shaft 5. The support frame 302 is provided with a shaft hole 302a, and the rotating protrusion 501 is rotatably disposed in the shaft hole 302a. The limiting part 303 includes a limiting protrusion 3031 protruding into the shaft hole 302a and a mating surface 501a provided on the outer wall of the rotating protrusion 501. The limiting protrusion 3031 abuts against the mating surface 501a, which can limit the rotation angle of the support frame 302.
[0050] Therefore, by setting the rotating protrusion 501 rotatably within the shaft hole 302a, it is beneficial to ensure that the support frame 302 and the footrest body 301 can rotate relative to each other without jamming. At the same time, by setting the mating surface 501a to abut against the limiting protrusion 3031 to limit the rotation angle of the support frame 302, without the need for additional limiting components, the space occupied by the limiting part 303 can be effectively reduced, making the footrest 3 easier to design and implement.
[0051] It is worth noting that, in specific implementation, it should be combined with Figures 10 to 12 As shown, the rotating shaft 5 includes a first half-shaft 5a and a second half-shaft 5b. Both the first half-shaft 5a and the second half-shaft 5b have a cross-section of 180° sector, and the radius of the first half-shaft 5a is larger than the radius of the second half-shaft 5b. The first half-shaft 5a and the second half-shaft 5b are fixedly connected along the same axis, allowing the rotating shaft 5 to be inserted into the footrest body 301 without rotation. Furthermore, the first half-shaft 5a can be extended axially into the shaft hole 302a to form a rotating protrusion 501, with the radius of the shaft hole 302a being the same as the radius of the first half-shaft 5a.
[0052] Of course, it is understandable that the above configuration is only one optional implementation of the rotating shaft 5 and the rotating protrusion 501. Other implementations can be adopted to enable the rotating protrusion 501 to rotate within the shaft hole 302a.
[0053] In specific implementation, combined with Figures 10 to 12 As shown, the limiting protrusion 3031 is configured as a fan-shaped plate structure with a cross-section of 90°, and the radius of the limiting protrusion 3031 is the same as the radius of the rotating protrusion 501. This configuration gives the limiting protrusion 3031 two mutually perpendicular limiting surfaces 3031a. The limiting protrusion 3031 protrudes into the shaft hole 302a, making the cross-section of the shaft hole 302a a fan shape of 270°. Based on the above overall description, when the support frame 302 and the footrest body 301 rotate relative to each other, causing the two limiting surfaces 3031a to abut against the mating surface 501a, the rotation angle of the support frame 302 can be limited, thereby enabling the support frame 302 to switch between the first state T1 and the second state T2.
[0054] In some of the exemplary implementations, combined with Figure 8 and Figure 9 As shown, the support frame 302 has a support protrusion 3021 protruding away from the shaft hole 302a, which is used to abut against an external carrier. In the second state T2, the support protrusion 3021 is biased on the side of the shaft hole 302a away from the mounting frame 2.
[0055] Therefore, by setting the support protrusion 3021 to be biased on the side of the shaft hole 302a away from the mounting bracket 2, when the support protrusion 3021 abuts against the external carrier, the reverse force of the external carrier on the support protrusion 3021 can apply a torque to the support frame 302, and the direction of this torque is opposite to the direction of the force required to fold the support frame 302. This arrangement can prevent the support frame 302 from folding on its own when the footrest body 301 is stepped on, thereby further ensuring the support stability of the footrest 3. The external carrier can be the vehicle floor or other components, depending on the installation environment of the seat.
[0056] It is worth noting that, in order to further improve the stability of the support frame 302 against the external carrier, in this embodiment, a notch 3021a is formed on one end of the support protrusion 3021 that abuts against the external carrier. This setting can reduce the contact area between the support protrusion 3021 and the external carrier, which is conducive to improving manufacturing precision and thus improving its stability.
[0057] In some of the exemplary implementations, combined with Figure 5 and Figure 6 As shown, the mounting bracket 2 includes a frame body 201 and a slider 202 protruding outward from the frame body 201. The frame body 201 is annular and has a receiving hole 201a. In the retracted state S1, the footrest body 301 and the support frame 302 are located in the receiving hole 201a, and the mounting bracket 2 is slidably mounted on the seat 1 via the slider 202.
[0058] Therefore, by allowing the footrest body 301 and the support frame 302 to be stored in the receiving hole 201a, the compactness of the footrest 3 in the storage state S1 can be improved in the first state T1, so as to further reduce the space occupied by storing the footrest 3.
[0059] It is understood that the slider 202 protruding outward from the frame body 201 means that the slider 202 protrudes outward from the frame body 201 along the sliding direction of the mounting bracket 2. In this embodiment, it specifically means that the slider 202 extends along the front-back direction of the seat 1.
[0060] Based on the above introduction, combined with Figure 4 , Figure 5 and Figure 13 As shown, in one embodiment where the mounting bracket 2 is slidably mounted on the seat 1 via the slider 202, a connecting member 8 is provided between the slider 202 and the frame 102 of the seat 1. This connecting member 8 includes a slide rail 801 extending along the front-rear direction of the seat 1, and a sliding bearing 802 connected to the slider 202. The slide rail 801 is fixed to the frame 102, and the sliding bearing 802 is slidably disposed within a groove 801a of the slide rail 801 along the extending direction of the slide rail 801. This arrangement allows the mounting bracket 2 to slide in a predetermined direction, thereby helping to ensure the stability of the sliding of the mounting bracket 2.
[0061] In some of the exemplary implementations, combined with Figure 5 As shown, one of the support frame 302 and the frame body 201 is provided with a limiting groove 6a, and the other is provided with a limiting block 6; the limiting block 6 can be inserted into the limiting groove 6a to limit the rotation angle of the footrest 3 when switching from the use state S2 to the storage state S1.
[0062] Therefore, by setting the limiting block 6 and the limiting groove 6a, when the foot support 3 switches from the use state S2 to the storage state S1, the excessive rotation of the support frame 302 can be effectively avoided, which is conducive to the support frame 302 being stored in the receiving hole 201a.
[0063] It is worth noting that, in specific implementation, as an optional embodiment of the setting of the limiting block 6 and the limiting groove 6a, the limiting block 6 is fixedly connected to the frame body 201, while the limiting groove 6a is formed on the support frame 302. Based on this, in this embodiment, taking the mounting frame 2 located on the right side of the seat 1 as an example, the limiting block 6 should be fixedly connected to the right side of the frame body 201.
[0064] It is understandable that when the mounting bracket 2 is installed on the left side of the seat 1, the limiting block 6 should be fixed to the left side of the frame body 201. Of course, the limiting block 6 can be set on the support frame 302, and the limiting groove 6a can be opened on the frame body 201. Alternatively, both the support frame 302 and the frame body 201 can be provided with limiting blocks 6 and limiting grooves 6a, so as to limit the rotation angle of the footrest 3 when switching from the use state S2 to the storage state S1. The specific configuration will not be described here.
[0065] In some of the exemplary implementations, combined with Figure 5 and Figure 6 As shown, a locking part 7 is provided between the mounting bracket 2 and the footrest 3, which can lock the footrest 3 in the folded state S1. Therefore, by providing the locking part 7, the footrest 3 can be effectively prevented from accidentally flipping over, which helps the footrest assembly to be stably kept in the folded state S1.
[0066] In some of the exemplary implementations, combined with Figure 5 and Figure 6 ,as well as Figure 15 and Figure 16 As shown, the locking part 7 includes a locking hole 7a on the footrest 3, a locking pin 701 slidably disposed on the mounting bracket 2, and an elastic part 702 disposed between the locking pin 701 and the mounting bracket 2. Under the action of the elastic part 702, the locking pin 701 is inserted into the locking hole 7a to restrict the footrest 3 from rotating relative to the mounting bracket 2.
[0067] Therefore, by providing the locking part 7 with an elastic part 702, when the corresponding lock hole 7a is locked, the locking pin 701 can be automatically inserted into the lock hole 7a under the drive of the elastic part 702, which improves the ease of use of the locking part 7. Furthermore, the elastic part 702 can keep the locking pin 701 in the lock hole 7a, thus ensuring the stability of the locking between the foot support 3 and the mounting bracket 2.
[0068] It is worth noting that, in specific implementation, it should be combined with Figure 16As shown, a locking hole 7a is provided on the footrest body 301. In this embodiment, the locking pin 701 includes a locking pin 7011, a pull rod 7012, and a pull head 7013. The mounting bracket 2 is provided with a relief groove 2a for the locking pin 7011 to be inserted. One end of the pull rod 7012 is fixedly connected to the pull head 7013, and the other end is inserted into the relief groove 2a and coaxially connected to the locking pin 7011. Thus, pulling the pull head 7013 allows the locking pin 7011 to slide in the relief groove 2a.
[0069] Based on this, in the preferred embodiment, the elastic part 702 is set as a spring, and the cross-sectional area of the pull rod 7012 is set to be smaller than the cross-sectional area of the locking pin 7011. This arrangement allows the spring to be sleeved on the outside of the pull rod 7012, so that one end of the spring abuts against the locking pin 7011 and the other end abuts against the bottom of the relief groove 2a, thereby providing the locking pin 7011 with the driving force to insert it into the lock hole 7a.
[0070] Preferably, the pull rod 7012 can be inserted into the locking pin 7011 and threadedly connected to the locking pin 7011. This arrangement makes it easier to put the spring on the pull rod 7012 and to put the locking pin 701 on the mounting bracket 2.
[0071] In some of the exemplary implementations, combined with Figure 4 , Figure 5 and Figure 14 As shown, the locking part 4 includes a retaining ring 401 provided on the seat 1 and a retaining block 402 provided on the mounting bracket 2. The retaining block 402 can be engaged in the retaining ring 401 to lock the mounting bracket 2 to the side of the seat 1.
[0072] Therefore, by providing a locking part 4 including a retaining ring 401 and a retaining block 402, the mounting bracket 2 can be locked to the side of the seat 1, and the mounting bracket 2 can be easily unlocked by adopting a snap-locking structure, which improves the ease of use.
[0073] Based on the above overall introduction, in this embodiment, the mounting bracket 2 includes a slider 202. In this embodiment, a locking block 402 is connected to the end of the slider 202 that is away from the frame body 201, and a retaining ring 401 is connected to the frame 102 of the seat 1. This arrangement is such that when the mounting bracket 2 is stored in the receiving cavity 1a, the locking block 402 can be locked in the retaining ring 401.
[0074] It is worth noting that, in specific implementation, this embodiment combines... Figure 14As shown, the retaining ring 401 is C-shaped, allowing it to elastically deform. This means that under external force, the gap between the two ends of the retaining ring 401 can increase, and it can return to its normal spacing when the external force disappears. Furthermore, the retaining block 402 has a pointed end near the retaining ring 401, and retaining grooves 402a are formed in the middle of opposite sides of the retaining block 402.
[0075] When the locking part 4 is used to fix the mounting bracket 2, pushing the mounting bracket 2 causes the end of the locking block 402 to insert into the gap between the two ends of the retaining ring 401. Guided by the end of the locking block 402, the gap between the two ends of the retaining ring 401 gradually increases, allowing the two ends of the retaining ring 401 to abut against the opposite sides of the locking block 402. As the locking block 402 is continuously inserted, when the two ends of the retaining ring 401 correspond to the retaining groove 402a, the two ends of the retaining ring 401 are engaged in the retaining groove 402a, thus locking the mounting bracket 2. To unlock, applying an opposing force to the mounting bracket 2 causes the two ends of the retaining ring 401 to disengage from the retaining groove 402a, thus unlocking the mounting bracket 2.
[0076] It is worth noting that, regarding the footrest assembly of this embodiment, based on the above exemplary embodiments, in specific implementation, as a preferred embodiment, it is still composed of... Figures 1 to 16 As shown, it may include, for example, a mounting bracket 2 that is slidably disposed on the side of the seat 1 in the front-back direction of the seat 1, a footrest 3 that is rotatably disposed on the mounting bracket 2, and a locking part 4 disposed between the mounting bracket 2 and the seat 1.
[0077] The locking part 4 can lock the mounting bracket 2 and the footrest 3 to the side of the seat 1. After unlocking, the mounting bracket 2 can slide to the outside of the seat 1 and switch the footrest 3 between the storage state S1 and the use state S2. In the storage state S1, the footrest 3 is folded on the mounting bracket 2. In the use state S2, the footrest 3 is flipped to the outside of the seat 1.
[0078] The footrest 3 includes a footrest body 301 rotatably mounted on the mounting bracket 2 at one end, a support frame 302 rotatably mounted on the other end of the footrest body 301, and a limiting part 303 disposed between the support frame 302 and the footrest body 301. The support frame 302 can switch between a first state T1 and a second state T2. In the first state T1, the support frame 302 is folded onto the footrest body 301. In the second state T2, the support frame 302 is supported under the footrest body 301. The limiting part 303 can limit the rotation angle of the support frame 302.
[0079] Furthermore, a locking part 7 is provided between the mounting bracket 2 and the footrest 3, which can lock the footrest 3 in the retracted state S1. The locking part 7 includes a locking hole 7a provided on the footrest 3, a locking pin 701 slidably provided on the mounting bracket 2, and an elastic part 702 provided between the locking pin 701 and the mounting bracket 2; under the action of the elastic part 702, the locking pin 701 is inserted into the locking hole 7a to restrict the footrest 3 from rotating relative to the mounting bracket 2.
[0080] In the preferred embodiment of the footrest assembly above, the specific configuration and arrangement of the footrest 3, locking part 4, locking part 7, etc. can still be referred to the description 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 locking part 7, etc., can also be referred to the description in the above exemplary embodiments.
[0081] The footrest assembly of this embodiment adopts the above design. When used to support the passenger's feet, firstly, the mounting bracket 2 is pulled along the front-to-back direction of the seat 1. At this time, the locking block 402 disengages from the locking ring 401, allowing the mounting bracket 2 to slide outside the receiving cavity 1a. Then, the locking pin 701 is pulled to disengage from the locking hole 7a, causing the footrest body 301 and the support frame 302 to flip over, so that the support frame 302 is supported on the carriage floor for passenger use.
[0082] When the footrest 3 is not in use, first, flip the support frame 302 and the footrest body 301 and store them in the receiving hole 201a. At the same time, pull the locking pin 701 so that the locking pin 701 is aligned with the locking hole 7a and inserted into the locking hole 7a, so that the footrest 3 is in the stored state S1. Then, push the mounting bracket 2 behind the seat 1 to complete the storage of the footrest assembly.
[0083] Therefore, by allowing the footrest 3 to switch between a usage state S2 and a storage state S1, when the footrest 3 is not in use, it locks itself to the side of the seat 1 to prevent interference with the passenger and reduce space occupation. When the footrest 3 is in usage state S2, it supports the passenger's feet, thus meeting the comfort needs of people of different heights and improving the seating comfort of the seat 1. At the same time, when the footrest 3 is in storage state S1, the locking part 4 effectively prevents the mounting bracket 2 from moving arbitrarily, ensuring that the footrest 3 can stably maintain the storage state S1.
[0084] An embodiment of the second aspect of this application provides a vehicle in which a seat 1 is provided with a footrest assembly as described in the first aspect embodiment.
[0085] The vehicle in this embodiment, by providing a footrest assembly as described in the first aspect embodiment on the seat 1, is conducive to meeting the comfort needs of passengers of different heights and in various application scenarios for the seat 1, thereby improving riding comfort.
