[0043] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0044] This embodiment relates to a vehicle seat. In terms of overall structure, a footrest 2 is provided on the backrest 1 of the vehicle seat, and a driving mechanism is provided between the backrest 1 and the footrest 2. The footrest 2 is driven by the driving mechanism to rotate relative to the backrest 1 and switch between an expanded state and a stored state. The backrest 1 includes a backrest frame 101 and a backrest trim 102 provided at the rear side of the backrest frame 101. A limiting portion is provided between the rotating shaft 3 of the footrest 2 and the backrest trim 102, and the limiting portion is used to limit the displacement of the backrest trim 102 along the left and right direction of the vehicle.

[0045] The vehicle seat of this embodiment is provided with a limiter between the rotating shaft 3 of the footrest 2 and the backrest trim 102, and the limiter limits the displacement of the backrest trim 102 along the left and right direction of the vehicle, which is conducive to improving the installation and positioning effect of the backrest trim 102 on the backrest frame 101, thereby improving the installation accuracy and efficiency of the backrest trim 102. The setting of the limiter is also conducive to improving the consistency of the peripheral gap between the footrest 2 and the backrest trim 102 in the storage state, thereby helping to improve the exquisiteness of the vehicle seat. In addition, by switching the footrest 2 between the unfolded state and the storage state, it is conducive to improving the comfort of the vehicle seat.

[0046] Based on the above overall introduction, an exemplary structure of the vehicle seat described in this embodiment is as follows Figures 1 to 5 As shown in . The rotating shaft 3 is installed at the bottom of the backrest frame 101 and is located at the front side of the backrest trim 102. The footrest 2 is plate-shaped and is located at the rear side of the backrest trim 102. In order to facilitate the connection between the footrest 2 and the rotating shaft 3, connecting plates 302 arranged close to each end are respectively provided on the rotating shaft 3. Each connecting plate 302 passes through the backrest trim 102 and is connected to the footrest 2, so that the footrest 2 can rotate synchronously with the rotating shaft 3. Among them, the through hole 1025 on the backrest trim 102 for each connecting plate 302 to pass through is in the shape of a long strip extending along the up and down direction of the whole vehicle, so as to facilitate the footrest 2 to switch between the storage state and the unfolded state.

[0047] As a preferred embodiment, Figure 5 and Figure 6As shown in , the limiting part in this embodiment includes a limiting plate 301 provided along the radial outward projection of the rotating shaft 3, and a limiting groove 1023 provided on the backrest trim 102. The limiting plate 301 is inserted into the limiting groove 1023 to limit the movement of the backrest trim 102 along the left and right direction of the vehicle. Here, the limiting plate 301 and the limiting groove 1023 have simple structures, and the cooperation between the two is conducive to the installation and positioning of the backrest trim 102, thereby facilitating the improvement of the installation accuracy and efficiency of the backrest trim 102.

[0048] In terms of specific structure, a limiting seat 1021 is provided on the backrest trim 102, and a protrusion 1022 is formed on the limiting seat 1021, and the protrusion 1022 protrudes in the direction away from the backrest trim 102. There are two protrusions 1022 arranged at intervals along the left and right direction of the vehicle, and they are surrounded to form a limiting groove 1023. Here, the two protrusions 1022 on the limiting seat 1021 form the limiting groove 1023, which is not only conducive to the structural formation of the limiting groove 1023, but also has a good limiting effect, further improving the installation effect of the backrest trim 102.

[0049] The limiting plate 301 is located in the middle of the rotating shaft 3, and the limiting seat 1021 is arranged in the middle of the rear side of the bottom of the backrest trim 102 corresponding to the limiting plate 301. Here, the limiting part is located in the middle of the rotating shaft 3 and the backrest trim 102 in the width direction, which is conducive to further improving the consistency of the gap between the footrest 2 and the outer periphery of the backrest trim 102 in the storage state. Compared with the solution without a limiting structure between the traditional footrest 2 and the backrest trim 102, the vehicle seat of this embodiment can avoid the problem of poor refinement of the vehicle seat caused by the large or small gap between the footrest 2 and the backrest trim 102.

[0050] The four corners of the limiting seat 1021 are respectively provided with connection holes 1024, and the limiting seat 1021 is connected to the backrest decorative plate 102 through the connection holes 1024. Preferably, the limiting plate 301 is in the shape of a disc coaxially arranged with the rotating shaft 3. In this way, when the limiting plate 301 rotates with the rotating shaft 3, it is beneficial to keep the limiting plate 301 in the limiting groove 1023, so as to have a better limiting matching effect. In addition, the middle part of each protrusion 1022 is concave, so that the protrusion 1022 is in the shape of an arc, which is beneficial to prevent the rotating shaft 3 from contacting the protrusion 1022 during the rotation process, thereby ensuring the smoothness of the use of the rotating shaft 3.

[0051] To facilitate the installation of the rotating shaft 3 on the backrest frame 101, as shown in FIG. Figure 3 As shown in the figure, brackets are connected to the left and right sides of the backrest frame 101 corresponding to the two ends of each rotating shaft 3. For the convenience of distinguishing description, the bracket connected to the left side of the backrest frame 101 is called the left bracket 305, and the bracket connected to the right side of the backrest frame 101 is called the right bracket 306. The rotating shaft 3 is rotatably arranged on the left bracket 305 and the right bracket 306.

[0052] As a preferred embodiment, the driving mechanism includes a rotary power device provided on the backrest frame 101, and a transmission mechanism provided between the rotary power device and the rotating shaft 3. The transmission mechanism includes a gear 402 provided at the output end of the rotary power device, and a toothed plate 304 provided on the rotating shaft 3, and the toothed plate 304 has a rack portion meshing with the gear 402. Here, by providing the rotary power device and the transmission mechanism, and the provision of the gear 402 and the toothed plate 304, it is convenient to drive the rotating shaft 3 to rotate, so that the footrest 2 can be switched between the unfolded state and the stowed state.

[0053] In terms of specific structure, Figures 7 to 11 As shown in , the rotary power device is a motor 4. To facilitate the arrangement of the motor 4, a motor bracket 401 is provided on the outside of the right bracket 306. The motor 4 is specifically installed on the outside of the motor bracket 401 and is connected to the right bracket 306 by passing through its own step bolts. The motor bracket 401 is located inside the right side of the backrest frame 101, and has two first front flanges 4011 folded forward, and a first rear flange 4012 folded backward. Bolts for connecting with the backrest frame 101 are penetrated on the first front flange 4011 and the first rear flange 4012, and a space for placing the motor 4 is formed between the motor bracket 401 and the backrest frame 101. The arrangement of the motor bracket 401 structure in this embodiment is conducive to avoiding the assembly relationship with the backrest angle adjustment motor, and is conducive to preventing the motor 4 from being bumped, and is not affected by the backrest frame 101 and the angle adjustment motor space, and is also conducive to arrangement and installation.

[0054] like Fig.13 As shown in the figure, the left bracket 305 in this embodiment is located inside the left side of the backrest frame 101 and has a second rear flange 3051 folded backward. The left bracket 305 is provided with a plurality of bolts passing through the second rear flange 3051 to be connected to the backrest frame 101. The left bracket 305 and the right bracket 306 in this embodiment have simple structures, high connection strength with the backrest frame 101, and both brackets are easy to process and form.

[0055] In addition, by arranging both the left bracket 305 and the right bracket 306 on the inner side of the backrest frame 101, it is beneficial to improve the space utilization of the backrest frame 101 and reduce the space occupied in the vehicle. Of course, in specific implementation, the structural form of the left bracket 305 and the right bracket 306 can also be adjusted according to the use requirements. It should be noted that the positions of the left bracket 305 and the right bracket 306 can also be swapped, and in this case, the rotary power device can be arranged on the left side of the backrest frame 101.

[0056] The tooth plate 304 in this embodiment is fan-shaped and is located between the left bracket 305 and the motor bracket 401. The rack portion on the tooth plate 304 is coaxially arranged with the rotating shaft 3, and the rack portion is specifically a plurality of meshing teeth that mesh with the gear 402. When the motor 4 drives the gear 402 to rotate, the rotation angle of the rotating shaft 3 can be changed by changing the meshing position of the gear 402 and the rack portion, thereby changing the state of the footrest 2. For example Fig.11 As shown in , when the gear 402 and the top of the rack portion remain engaged, the footrest 2 is in the stowed state. Fig.12 As shown in FIG, when the gear 402 and the bottom of the rack portion remain engaged, the foot rest 2 is in the unfolded state.

[0057] As a preferred embodiment, an elastic member is sleeved on the rotating shaft 3, and the two ends of the elastic member are respectively connected to the backrest 1 and the footrest 2, and can apply a driving force to the expansion of the footrest 2. By arranging the elastic member on the rotating shaft 3, it is helpful to improve the stability of the footrest 2 in use. In particular, considering that the gear 402 and the rack part have deviations due to processing accuracy, the cooperation of the elastic member is helpful to eliminate the movement gap between the gear 402 and the rack part, and prevent vibration caused by the gap between the two, thereby helping to improve the meshing stability of the gear 402 and the rack part, and then improve the use stability of the footrest 2.

[0058] like Figure 7 and Figure 8 As shown in the figure, the elastic member in this embodiment is two torsion springs 303 arranged on the rotating shaft 3, and the two torsion springs 303 are respectively sleeved on the rotating shaft 3 and located on the left and right sides of the limiting plate 301. One end of the torsion spring 303 is constrained on the backrest frame 101, and the other end of the torsion spring 303 is connected to the connecting plate 302. The torsion spring 303 here is a mature product, easy to arrange, and has a good use effect.

[0059] Further Figure 7 As shown in , a sleeve 308 is sleeved on the rotating shaft 3, and the elastic member is sleeved outside the sleeve 308. The sleeve 308 on the rotating shaft 3 is helpful to prevent abnormal noise caused by the collision between the elastic member and the rotating shaft 3. In a specific implementation, the sleeves 308 are two, respectively arranged between each torsion spring 303 and the rotating shaft 3, and respectively located between the connecting plate 302 and the limiting plate 301. The sleeve 308 is preferably made of polyvinyl chloride. Here, the sleeve 308 is made of polyvinyl chloride, which is easy to process and shape, and has a good effect of preventing abnormal noise. Of course, in a specific implementation, the material of the sleeve 308 can also be adjusted according to the use requirements.

[0060] In addition, a blocking portion 307 is provided on the rotating shaft 3, and the blocking portion 307 abuts against the sleeve 308, so as to prevent the sleeve 308 from moving along its axial direction. By providing the blocking portion 307 to prevent the sleeve 308 from moving along the axial direction, the stability of the sleeve 308 in use is improved. Fig.10 As shown in FIG. 3 , one end of the sleeve 308 abuts against the connecting plate 302, and the blocking portion 307 is provided at the other end of the sleeve 308. The connecting plate 302 and the blocking portion 307 cooperate to limit the movement of the sleeve 308 in its own axial direction. Of course, the sleeve 308 and the connecting plate 302 are spaced apart, and in this case, the blocking portion 307 needs to be provided at both ends of the sleeve 308 to ensure the reliability of the sleeve 308.

[0061] In a specific implementation, the blocking portion 307 includes felt coated on the rotating shaft 3. The felt has the advantages of being easy to implement and having a good limiting effect. Of course, in a specific implementation, the material of the blocking portion 307 and the arrangement method on the rotating shaft 3 can also be adjusted according to the use requirements.

[0062] As a preferred embodiment, Figure 2 As shown in the figure, in this embodiment, a receiving groove 1026 is provided at the rear side of the backrest trim 102, and the footrest 2 in the stored state is stored in the receiving groove 1026. Here, by storing the footrest 2 in the stored state in the receiving groove 1026, it is beneficial to improve the flatness of the backrest 1 and reduce the amount of space occupied by the footrest 2 in the vehicle. In this embodiment, by setting the limiting part, the gap between the outer periphery of the footrest 2 and the receiving groove 1026 has good consistency, which is beneficial to enhance the exquisiteness of the vehicle seat.

[0063] When installing the vehicle frame in this embodiment, the rotating shaft 3 is first installed on the backrest frame 101 through the left bracket 305, the right bracket 306 and the motor bracket 401, and then the foam body and surface guard and other exterior decorations on the seat are installed. Then, the backrest decorative panel 102 is installed through the cooperation of the limiting plate 301 and the limiting groove 1023, and finally the footrest 2, interior decorative panel and exterior decorative panel are installed.

[0064] The vehicle seat in this embodiment optimizes its own structure, makes the driving mechanism simple and stable, and requires little space for arrangement, thus solving the problem that the vehicle seat has a small internal space and cannot be arranged. In addition, the assembly of the entire vehicle seat is simple, which is conducive to improving assembly accuracy and assembly efficiency.

[0065] In addition, the present embodiment also relates to a vehicle, on which the vehicle seat as described above is provided.

[0066] The vehicle of this embodiment is provided with the vehicle seat as described above, which helps to improve the assembly efficiency and comfort of the vehicle.

[0067] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
