[0043] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0044] Please refer to the following Figures 1 to 10 A footrest assembly, a seat, and a vehicle according to embodiments of the present invention are described.

[0045] like Figures 1 to 8As shown, the footrest assembly according to an embodiment of the present invention includes a footrest 3 and a connecting device 2. The connecting device 2 includes a rotating arm assembly 22 and a driving assembly 21. The rotating arm assembly 22 is connected to the footrest 3 and the seat frame 4, and the rotating arm assembly 22 can rotate relative to the seat frame 4 to drive the footrest 3 to move between the unfolded position and the folded position. The driving assembly 21 includes a driving member 213, a rotating member 211 and a translation member 212, the driving member 213 is connected to the rotating member 211 to drive the rotating member 211 to rotate, the rotating member 211 is connected to the translation member 212, the translation member 212 is connected to the rotating arm assembly 22, and the rotating member 211 can drive the translation member 212 to translate to drive the rotating arm assembly 22 to rotate.

[0046] It is understandable that when the footrest 3 is in the folded position, the footrest 3 fits the rear side of the back plate 1. When the footrest 3 is in the unfolded position, a certain angle is formed between the footrest 3 and the back plate 1.

[0047] According to the footrest assembly of the embodiment of the present invention, when the footrest 3 needs to be adjusted, the driving member 213 can be used to drive the rotating member 211 to rotate, the rotating member 211 can drive the translation member 212 to translate, and the translation member 212 can drive the rotating arm assembly 22 to rotate, so that the rotating arm assembly 22 drives the footrest 3 to move between the unfolded position and the folded position. The footrest assembly of the embodiment of the present invention has a small number of parts by setting the driving assembly 21 to the above-mentioned structure, which can reduce the space occupied by the driving assembly 21, and the structural design is compact, which is conducive to improving the space utilization of the seat and does not affect the arrangement of other parts of the seat.

[0048] Optionally, the rotating member 211 and the translation member 212 may be a gear rack transmission pair, that is, the rotating member 211 is a gear 2111, and the translation member 212 is a rack 2121. Alternatively, the rotating member 211 and the translation member 212 may also be a screw nut transmission pair, that is, the rotating member 211 is a nut, and the translation member 212 is a screw.

[0049] In a specific example, if Figures 6 to 8As shown, the driving member 213 is a driving motor, the rotating member 211 is a gear 2111, and the translation member 212 is a rack 2121. The gear 2111 is meshed with the rack 2121. One end of the rack 2121 in the length direction is pivotally connected to the rotating arm assembly 22. The pivot position of the rack 2121 and the rotating arm assembly 22 is linearly separated from the rotating shaft 221 of the rotating arm assembly 22. It can be understood that the gear 2111 is connected to the output shaft of the driving motor, and the driving motor drives the gear 2111 to rotate so that the rack 2121 translates along the tangent direction of the pitch circle of the gear 2111, and the rack 2121 can drive the rotating arm assembly 22 to rotate around its rotating shaft 221. The footrest assembly of the embodiment of the present invention can make the transmission of the rotating member 211 and the translation member 212 stable, not easy to be damaged, and have a high transmission efficiency by setting the driving assembly 21 as the above structure.

[0050] For example, Fig. 9 As shown, a boss 21211 is provided at one end of the rack 2121 adjacent to the rotating arm 222, and the boss 21211 extends along the thickness direction of the rack 2121. A matching hole 2221 is provided on the rotating arm 222, and the boss 21211 is inserted into the matching hole 2221 and rotatably matched with the matching hole 2221. A rack fixing gasket 21212 and a rack fixing nut 21213 are provided at the end of the boss 21211, and the rack fixing gasket 21212 is provided between the boss 21211 and the rack fixing nut 21213, so that the boss 21211 can be installed in the matching hole 2221 and rotatably matched with the matching hole 2221.

[0051] In some embodiments, Figure 6 and Figure 7 As shown, the driving assembly 21 also includes a first fixed bracket 214 and a guide member 215. The first fixed bracket 214 is connected to the seat frame 4, the driving member 213 is connected to the first fixed bracket 214, the guide member 215 is arranged on the first fixed bracket 214, and a guide groove 2155 is arranged on the guide member 215. The rack 2121 slides with the guide groove 2155 along its length direction. It can be understood that the first fixed bracket 214 is arranged on the left or right side of the seat frame 4. The first fixed bracket 214 is detachably connected to the seat frame 4 and the driving member 213. When the gear 2111 rotates to drive the rack 2121 to move, the rack 2121 can translate under the limiting effect of the guide groove 2155.

[0052] For example, Figure 6 and Figure 7As shown, one side of the width direction of the rack 2121 has a tooth surface, which meshes with the gear 2111. The other side of the width direction of the rack 2121 is embedded in the guide groove 2155, so that the rack 2121 can only translate along its length direction. The footrest assembly of the embodiment of the present invention can provide guidance for the movement of the rack 2121 by providing the guide member 215, so as to ensure the smooth movement of the rack 2121, which is beneficial to improve the transmission efficiency of the drive assembly 21.

[0053] In one example, if Fig. 9 As shown, the guide member 215 includes a column 2151, a first limiting plate 2152 and a second limiting plate 2153. The column 2151 is connected to the first fixed bracket 214. The first limiting plate 2152 and the second limiting plate 2153 are arranged at intervals along the length direction of the column 2151 to form a guide groove 2155. It can be understood that the axis of the column 2151 is arranged parallel to the axis of the gear 2111. The first limiting plate 2152 and the second limiting plate 2153 are both circular. Since the first limiting plate 2152 and the second limiting plate 2153 are arranged at intervals along the length direction of the column 2151, an annular guide groove 2155 can be formed. The footrest assembly of the embodiment of the present invention can reduce the volume of the guide member 215 and the space occupied by the guide member 215 by setting the guide member 215 to the above structure, and is easy to assemble, and has a good guiding effect.

[0054] For example, Fig. 9 As shown, a first bushing 2154 is rotatably sleeved on the column 2151, and the first bushing 2154 is arranged in the guide groove 2155 and abuts against the rack 2121. When the rack 2121 moves relative to the guide groove 2155, the first bushing 2154 can rotate relative to the column 2151, so that the rack 2121 can move more smoothly and the transmission effect is better.

[0055] Alternatively, if Figure 7 and Fig. 9 As shown, the driving assembly 21 also includes a fixed cover 216, which is arranged on the side of the first fixed bracket 214 away from the driving member 213. The fixed cover 216, the first fixed bracket 214 and the driving member 213 are connected by a motor fixing bolt 218, and the end of the motor fixing bolt 218 is screwed with a motor fixing nut 217.

[0056] In some embodiments, Figure 6As shown, the rotating arm assembly 22 includes a rotating shaft 221 and at least two rotating arms 222. The length direction of the rotating shaft 221 is consistent with the left-right direction of the seat frame 4. The two rotating arms 222 are arranged at intervals along the length direction of the rotating shaft 221 and can rotate along the axis of the rotating shaft 221. The rotating arms 222 are all connected to the footrest 3, and at least one rotating arm 222 is connected to the translation member 212. It can be understood that there can be two or more rotating arms 222, and the translation member 212 can be connected to one or more rotating arms 222. In other words, when the translation member 212 drives one rotating arm 222 to rotate, multiple rotating arms 222 can rotate synchronously.

[0057] For example, Figure 6 and Fig. 9 As shown, there are two rotating arms 222 , which are spaced apart along the axis of the rotating shaft 221 . The rotating shaft 221 is relatively fixed to the seat frame 4 , and the rotating arms 222 are rotatable relative to the rotating shaft 221 .

[0058] Alternatively, if Figure 6 and Fig. 9 As shown, the rotating arm assembly 22 further includes a rotating shaft bracket 223, the rotating shaft 221 is detachably connected to the rotating shaft bracket 223 and is matched with the rotating shaft bracket 223 to prevent rotation, and the rotating shaft bracket 223 is detachably connected to the seat frame 4. Specifically, the rotating shaft bracket 223 is arranged at one end of the rotating shaft 221 away from the first fixed bracket 214, the rotating arm assembly 22 further includes a rotation limiting piece 225 and a rotating shaft fixing bolt 226, the rotating shaft fixing bolt 226 fixes the rotating limiting piece 225 on the rotating shaft 221, and the rotating shaft bracket 223 is provided with a clamping hole 2231, and the rotating limiting piece 225 is clamped in the clamping hole 2231, so that the rotating shaft 221 can be limited from rotating relative to the rotating shaft bracket 223.

[0059] Alternatively, if Figure 6 and Fig. 9 As shown, the rotating arm assembly 22 further includes a first elastic member 224, which is disposed on the rotating shaft 221 and connected to the seat frame 4. The first elastic member 224 has an elastic force that drives the footrest 3 to move from the unfolded position to the folded position. For example, the first elastic member 224 is a torsion spring, and the rotating arm assembly 22 further includes a second bushing 227, which is rotatable relative to the rotating shaft 221, and the first elastic member 224 is sleeved on the second bushing 227 and connected to the seat frame 4. The footrest assembly of the embodiment of the present invention is provided with the first elastic member 224, so that the footrest 3 can automatically move from the unfolded position to the folded position, thereby achieving a better use effect of the footrest 3.

[0060] like Fig.10As shown, a seat according to another embodiment of the present invention comprises: a back plate 1, a seat frame 4 and a footrest assembly, wherein the back plate 1 is arranged on the seat frame 4. The footrest assembly is the footrest assembly of the embodiment of the present invention, and the driving member 213 and the rotating arm assembly 22 are both connected to the seat frame 4. It can be understood that the back plate 1 is arranged on the rear side of the seat frame 4, and the footrest 3 is arranged on the rear side of the back plate 1.

[0061] According to the seat of the embodiment of the present invention, when the footrest 3 needs to be adjusted, the driving member 213 can be used to drive the rotating member 211 to rotate, the rotating member 211 can drive the translation member 212 to translate, and the translation member 212 can drive the rotating arm assembly 22 to rotate, so that the rotating arm assembly 22 drives the footrest 3 to move between the unfolded position and the folded position. The footrest assembly of the seat of the embodiment of the present invention has a small number of parts by setting the driving assembly 21 to the above-mentioned structure, which can reduce the space occupied by the driving assembly 21, and the structural design is compact, which is conducive to improving the space utilization of the seat and does not affect the arrangement of other parts of the seat.

[0062] In some embodiments, Figure 5 , Figure 6 and Fig. 9 As shown, the back plate 1 is provided with a mounting hole 11, the rotating arm assembly 22 is inserted into the mounting hole 11, the footrest assembly further includes a shielding assembly 23, the driving member 213 is provided at one side of the back plate 1 and is connected to the rotating arm assembly 22 and the shielding assembly 23, and in the unfolded position, the shielding assembly 23 covers at least part of the mounting hole 11. It can be understood that the driving member 213 is provided at the front side of the back plate 1, the footrest 3 is provided at the rear side of the back plate 1, the rotating arm 222 is respectively connected to the driving member 213 and the footrest 3, and the rotating arm 222 is inserted into the mounting hole 11. Since the shielding assembly 23 covers at least part of the mounting hole 11 in the unfolded position, the gap between the rotating arm 222 and the mounting hole 11 can be shielded to prevent the internal parts structure of the seat from being exposed, thereby improving the sealing and dustproof effect of the seat, and providing a better user experience.

[0063] It is understandable that if Figures 6 to 8 As shown, the shielding component 23 is a movable component. When the footrest 3 is in the folded position, in order to avoid interference between the rotating arm 222 and the shielding component 23, the driving component 213 can drive the shielding component 23 to be spaced apart from the mounting hole 11.

[0064] Alternatively, if Figures 6 to 8As shown, the shielding assembly 23 is connected to the rotating arm 222, and the rotating arm 222 can drive the shielding assembly 23 to move between the shielding position covering the mounting hole 11 and the recovery position avoiding the mounting hole 11. It can be understood that the driving member 213 can drive the rotating arm 222 to rotate, and the rotating arm 222 can synchronously drive the shielding assembly 23 to be linked, so the shielding assembly 23 and the rotating arm 222 can share a power source, thereby reducing the number of parts of the footrest assembly, reducing the occupied space of the footrest assembly, and making the linkage effect of the footrest assembly better, which is conducive to improving the transmission efficiency.

[0065] In the first embodiment, if Figures 6 to 9 As shown, the shielding assembly 23 includes a shielding cover 231 and a first linkage component 232. The rotating arm assembly 22 is pivotally connected to the shielding cover 231. One end of the first linkage component 232 is pivotally connected to the shielding cover 231. The other end of the first linkage component 232 is relatively fixed to the back plate 1. In the shielding position, the shielding cover 231 is located between the upper edge of the mounting hole 11 and the rotating arm assembly 22. In the retracted position, the shielding cover 231 is located on the side of the back plate 1 away from the footrest 3 and is spaced apart from the mounting hole 11.

[0066] It can be understood that when the shielding cover 231 moves from the shielding position to the recovery position, the driving member 213 drives the rotating arm 222 to rotate, and the rotating arm 222 drives the shielding cover 231 to rotate, and due to the restraint and guiding effect of the first linkage component 232, the shielding cover 231 also rotates relative to the first linkage component 232, so that the shielding cover 231 is separated from the mounting hole 11 and does not interfere with other components in the seat.

[0067] For example, in the shielding position, the outer surface of the shielding cover 231 and the outer surface of the rotating arm 222 are located in the same horizontal plane, thereby improving the flatness of the back panel 1 and improving the shielding effect of the seat.

[0068] Alternatively, if Figures 6 to 9 As shown, the first linkage component 232 includes a first fixing seat 2321, a first connecting rod 2322 and a second elastic member 2323. One end of the first connecting rod 2322 (such as Figure 7 The lower end of the first connecting rod 2322) is pivotally connected to the shielding cover 231, and the other end of the first connecting rod 2322 (such as Figure 7 The upper end of the first connecting rod 2322 is pivotally connected to the first fixing seat 2321, and the first fixing seat 2321 is installed on the seat frame 4 and relatively fixed to the back plate 1 and the seat frame 4. The second elastic member 2323 is connected to the shielding cover 231 and the first connecting rod 2322, and the second elastic member 2323 has an elastic force that drives the shielding cover 231 to move from the retracted position toward the shielding position.

[0069] It is understandable that when the shielding cover 231 gradually moves from the retracted position toward the shielding position, the angle between the shielding cover 231 and the first connecting rod 2322 gradually increases and finally becomes substantially 180°. When the shielding cover 231 gradually moves from the shielding position toward the retracted position, the shielding cover 231 gradually moves away from the back plate 1, and the angle between the shielding cover 231 and the first connecting rod 2322 gradually decreases. The seat of the embodiment of the present invention can improve the stability of the transmission of the shielding cover 231 and the rotating arm 222 by setting the shielding assembly 23 as the above-mentioned transmission structure, and is easy to process and manufacture.

[0070] Specifically, Figures 7 to 9 As shown, the first linkage component 232 also includes a first rotating shaft 2324 and a second rotating shaft 2325. The length directions of the first rotating shaft 2324 and the second rotating shaft 2325 are both consistent with the left-right direction of the back plate 1. The first rotating shaft 2324 is rotatably penetrated in the first fixed seat 2321, and the second rotating shaft 2325 is rotatably penetrated in the shielding cover 231. The first connecting rod 2322 has a first support arm 23221 and a second support arm 23222. The first support arm 23221 and the second support arm 23222 are arranged at intervals along the length direction of the first rotating shaft 2324. The first support arm 23221 and the second support arm 23222 are both connected to the second rotating shaft 2325. The second elastic member 2323 is a torsion spring, which is sleeved on the second rotating shaft 2325 and connected to the shielding cover 231.

[0071] It is understandable that if Figures 7 to 9 As shown, the first connecting rod 2322 can rotate relative to the first fixed seat 2321 around the axis of the first rotating shaft 2324, and the shielding cover 231 can rotate relative to the first connecting rod 2322 around the axis of the second rotating shaft 2325. The first linkage component 232 also includes a third rotating shaft 2326, and the third rotating shaft 2326 is located below the second rotating shaft 2325, and the first rotating shaft 2324 is located above the second rotating shaft 2325. The third rotating shaft 2326 is rotatably arranged in the rotating arm 222, and the shielding cover 231 is connected to the third rotating shaft 2326, and the shielding cover 231 can rotate relative to the rotating arm 222 around the axis of the third rotating shaft 2326. The seat of the embodiment of the present invention can improve the stability of the transmission of the first linkage component 232 by setting the first linkage component 232 as the above structure, and is not easy to be damaged and has a long service life.

[0072] In the second embodiment, the shielding assembly 23 includes a shielding cover 231, which is elastic and connected to the back plate 1. In the unfolded position, the shielding cover 231 covers the mounting hole 11. In the folded position, the rotating arm assembly 22 squeezes the shielding cover 231 to elastically deform the shielding cover 231 and avoid the mounting hole 11. For example, the shielding cover 231 is an elastic rubber sheet or a spring sheet, and the shielding cover 231 can be elastically deformed under the action of an external force.

[0073] It is understandable that when the footrest 3 is in the unfolded position, a gap appears between the rotating arm assembly 22 and the mounting hole 11, and the shielding cover 231 covers the gap between the rotating arm assembly 22 and the mounting hole 11. When the footrest 3 moves from the unfolded position to the folded position, due to the squeezing effect of the rotating arm assembly 22, the shielding cover 231 can be elastically deformed, so that it can avoid the mounting hole 11 under the squeezing effect of the rotating arm assembly 22, and will not interfere with the movement trajectory of the rotating arm assembly 22. When the footrest 3 moves from the folded position to the unfolded position, the rotating arm assembly 22 is gradually separated from the shielding cover 231, so the shielding cover 231 can be elastically reset and re-cover the mounting hole 11, thereby improving the shielding effect of the seat gap, and the structural design is simple and the processing cost is low.

[0074] In the third embodiment, the shielding assembly 23 includes a shielding cover 231 and a traction member (not shown), the shielding cover 231 is pivotally connected to the back panel 1, one end of the traction member is connected to the shielding cover 231, and the other end of the traction member is connected to the rotating arm assembly 22, and the rotating arm assembly 22 can drive the traction member to move to drive the shielding cover 231 to rotate between a shielding position covering the mounting hole 11 and a recovery position avoiding the mounting hole 11.

[0075] For example, the traction rope can be a flexible member such as a wire rope or a spring. When the footrest 3 moves from the unfolded position to the folded position, the rotating arm assembly 22 can drive the traction member to move, and the traction rope can synchronously drive the shielding cover 231 to rotate, so that the shielding cover 231 gradually moves away from the mounting hole 11. When the footrest 3 moves from the folded position to the unfolded position, the rotating arm assembly 22 can drive the traction member to move, so that the shielding cover 231 gradually approaches and covers the mounting hole 11. The footrest assembly of the embodiment of the present invention can improve the linkage effect of the rotating arm assembly 22 and the shielding assembly 23 by setting the shielding assembly 23 to the above-mentioned structure, avoid the problem of interference between the rotating arm assembly 22 and the shielding cover 231, and improve the reliability of the movement of the shielding assembly 23.

[0076] In some embodiments, Figure 5 and Fig. 9 As shown, there are two rotating arms 222, and the two rotating arms 222 are arranged at intervals along the axis of the rotating shaft 221. There are two mounting holes 11, and the two mounting holes 11 are arranged at intervals along the axis of the rotating shaft 221 on the back plate 1, and the two mounting holes 11 correspond to the two rotating arms 222. Correspondingly, there are two shielding components 23, and the two shielding components 23 are respectively installed on the two rotating arms 222, so that the two mounting holes 11 can be shielded by the two shielding components 23.

[0077] In some embodiments, Fig. 9As shown, the footrest 3 includes an upper plate 31, a lower plate 32 and a support frame 33, wherein the support frame 33 is disposed between the upper plate 31 and the lower plate 32, and the support frame 33 is connected to the rotating arm 222. Optionally, the footrest 3 further includes a fixed plastic part 34, which is disposed between the upper plate 31 and the lower plate 32 to further improve the structural strength of the footrest 3.

[0078] For example, Fig. 9 As shown, the support frame 33 and the rotating arm 222 are connected by the foot support fixing bolt 35, so as to facilitate the installation and disassembly of the support frame 33 and the rotating arm 222.
