[0053] In this document, “equal”, “same”, etc. are not strictly limited in a mathematical and / or geometric sense, but also include errors that can be understood by those skilled in the art and are allowed in manufacturing or use.

[0054] Unless otherwise stated, the numerical ranges herein include not only the entire range within its two endpoints but also include several sub-ranges contained therein.

[0055] Figure 1 A seat back plate 100 of a seat is shown. The seat back plate 100 is provided with an opening 101, and a support plate 110 is provided on the outer side of the seat back plate 100. A support rod 120 is provided inside the seat. The support rod 120 drives the support plate 110 through the opening 101, so as to realize the expansion and retraction of the support plate 110.

[0056] Therefore, when the tray 110 is unfolded, the portion of the opening 101 above the tray 110 is exposed. When the tray 110 is in use, foreign objects may easily enter the seat through the opening 101, which may affect the transmission of the support rod 120 and other components in the seat, thereby increasing the failure rate of the seat. In addition, the design of the exposed opening 101 is not beautiful.

[0057] For this purpose, refer to Figures 2 to 10 The utility model discloses a support plate device, which includes a support plate 110, a support rod 120 and a cover 130. The cover 130 is connected to the support rod 120, and the support rod 120 extends into the seat through an opening 101 of the seat. When the support rod 120 drives the cover 130 to move out of the seat, the cover 130 is blocked by the seat to cover the opening 101.

[0058] According to the pallet device of the present invention, when the support rod 120 drives the pallet 110 to unfold, the cover 130 first moves with the movement of the support rod 120 until the cover 130 is blocked by the seat and covers the opening 101, thereby preventing foreign objects from entering the opening 101 and affecting the use of the pallet device, thereby reducing the failure rate.

[0059] Furthermore, the first end of the support rod 120 extends into the seat through the opening 101 of the seat, and the second end of the support rod 120 is connected to the support plate 110. The support rod 120 is rotatably arranged between an extended position and a retracted position relative to the seat. When the support rod 120 is in the extended position, the support plate 110 is extended and can be used to support the legs of a human body; and when the support rod 120 is in the retracted position, the support plate 110 is attached to the seat back plate 100 of the seat along with the support rod 120.

[0060] Reference Figure 2 and Figure 3 The support device further includes a transverse tube 160 and a driving member 170. The transverse tube 160 is disposed in the seat and is rotatable relative to the seat. Figure 4 and Figure 5 As shown, the support plate device includes two support rods 120, and the two support rods 120 are connected to the cross tube 160. When the cross tube 160 rotates, the two support rods 120 are driven to rotate, thereby driving the support plate 110 to move. The driving member 170 is disposed on the seat and located at one end of the cross tube 160 (for example Figure 2 and Figure 3 As shown, the driving member 170 is located at the right end of the cross tube 160, and the driving member 170 is connected to the cross tube 160. The driving member 170 can be optionally a motor, and when the driving member 170 is started, the driving member 170 drives the cross tube 160 to rotate, so that the support rod 120 is rotatably arranged between the deployed position and the retracted position.

[0061] Optionally, refer to Figure 2 and Figure 3 A second elastic member 180 is sleeved on the transverse tube 160 , a first end of the second elastic member 180 is fixed to the transverse tube 160 , and a second end of the second elastic member 180 is fixed relative to the seat (specifically the seat back panel 100 ), so that the transverse tube 160 can be reset in cooperation with the driving member 170 .

[0062] For details, refer to Figure 5 The support plate 110 includes an upper cover plate 111 and a lower cover plate 112. The upper cover plate 111 and the lower cover plate 112 are buckled and fixed. The upper cover plate 111 and the lower cover plate 112 can be fixed by clamping, or can be fixed together by fasteners 190 or welding. The end of the support rod 120 away from the cross tube 160 extends into between the upper cover plate 111 and the lower cover plate 112. The support rod 120 is provided with a mounting hole so that it can be fixed to the lower cover plate 112 by fasteners 190, so that the support plate 110 and the support rod 120 are fixed together.

[0063] Figure 6 A support plate device (hidden support plate 110) according to the utility model is shown, combined with Figure 2 As shown, the support plate device includes two second connecting members 161 and a third connecting member 171, and the two second connecting members 161 are respectively arranged at both ends of the transverse tube 160, and the second connecting members 161 are fixed relative to the seat. Optionally, the second connecting member 161 is a sheet metal part and is fixed to the inner side of the seat back plate 100 by a fastener 190, and the end of the transverse tube 160 is passed through the second connecting member 161, so that the transverse tube 160 is rotatably arranged relative to the seat.

[0064] Continue to refer to Figure 2 and Figure 6 The third connecting member 171 can be a sheet metal part and is fixed to the inner side of the seat back plate 100 by a fastener 190, and the driving member 170 is fixed to the third connecting member 171 by a fastener 190, so that the driving member 170 is fixed relative to the seat (specifically, the seat back plate 100). The installation of the cross tube 160 and the driving member 170 is achieved by the second connecting member 161 and the third connecting member 171, which has a compact structure and high connection strength.

[0065] Refer to Figure 7The second connecting member 161 and the third connecting member 171 are constructed to form an accommodation space. Specifically, the second connecting member 161 is bent to form a U-shaped groove. The second connecting member 161 is connected to the connecting portion 121 by a fastener 190, thereby forming an accommodation space. The right end of the transverse tube 160 is passed through the accommodation space and is provided with a transmission gear 162. The output end of the driving member 170 is provided with a driving gear 172. The driving gear 172 and the transmission gear 162 are both arranged in the accommodation space and meshed. Therefore, when the driving member 170 is started, the driving gear 172 rotates, so that the transmission gear 162 and the transverse tube 160 rotate, thereby driving the support rod 120 and the support plate 110.

[0066] Preferably, the transmission gear 162 is an incomplete gear. When the support rod 120 is located at the retracted position and the deployed position, the driving gear 172 is respectively engaged with the two end points of the toothed stroke connected to the transmission gear 162. Therefore, the transmission gear 162 is configured as an incomplete gear, which can limit the rotation stroke of the cross tube 160 and the support rod 120 and prevent the support plate 110 from excessive rotation and causing bump damage.

[0067] Optionally, the cover 130 is movably connected to the support rod 120 , so that it can move with the support rod 120 and cover the opening 101 under the blocking effect of the seat.

[0068] As an alternative, the cover 130 may also be fixed relative to the support rod 120 , and the cover 130 may be made of elastic material such as rubber, so as to move with the support rod 120 and cover the opening 101 under the blocking effect of the seat.

[0069] Preferably, the support plate device further comprises a first elastic member 140, which is disposed on the support rod 120 and connected to the cover 130, so that the cover 130 can maintain a state of being pressed against the seat when being blocked by the seat.

[0070] Optionally, the cover 130 can be made by a stamping process and provided with a protrusion 132, which protrudes toward the support rod 120, so that when the support rod 120 extends out of the opening 101, the protrusion 132 of the cover 130 can fit into the opening 101, so that the cover 130 can well cover the opening 101.

[0071] Optionally, a limit opening 131 is further provided at the top of the cover 130. When the support rod 120 is in the retracted position, the limit opening 131 of the cover 130 is sleeved onto the support rod 120, so that the cover 130 can have a good fit with the push rod, preventing the cover 130 from being deflected and unable to cover the opening 101.

[0072] Reference Figure 2 and Figure 6The support rod 120 is provided with a connecting portion 121, and the cover 130 and the elastic member are both provided at the connecting portion 121. The cover 130 and the first elastic member 140 are integrated together to improve assembly efficiency.

[0073] Optionally, refer to Figure 8 The connecting part 121 is a sheet metal part, and the connecting part 121 is a semi-tube structure and is sleeved on the supporting rod 120. The connecting part 121 and the supporting rod 120 are fixed by fasteners 190, so that the connecting part 121 and the supporting rod 120 have sufficient connection contact area and the connection is stable.

[0074] Optionally, refer to Figure 8 The connecting portion 121 is provided with a first plug hole 122 and a second plug hole 124, and the connecting portion 121 is provided with a first pin shaft 123 and a second pin shaft 125. The first pin shaft 123 is inserted into the connecting portion 121 through the first plug hole 122, and the second pin shaft 125 is inserted into the connecting portion 121 through the second plug hole 124. Further, the first pin shaft 123 is penetrated by the cover 130, so that the cover 130 can be rotatably arranged relative to the support rod 120, and the second pin shaft 125 is arranged parallel to the first pin shaft 123. The first elastic member 140 is sleeved on the second pin shaft 125, and the first end of the first elastic member 140 is connected to the connecting portion 121, and the second end of the first elastic member 140 abuts against the cover 130. Therefore, the first elastic member 140 has an elastic force on the cover 130, so that the cover 130 moves with the rotation of the support rod 120 and can abut against the inner side of the opening 101 of the seat back plate 100, thereby covering the opening 101.

[0075] Reference Figure 8 The second pin 125 is located on the side of the first pin 123 away from the middle of the cover 130, and the second end of the first elastic member 140 extends toward the cover 130 and bypasses the first pin 123. Therefore, the first elastic member 140 has a larger force arm for driving the cover 130, ensuring that the first elastic member 140 has sufficient elastic force on the cover 130.

[0076] Optionally, the second end of the first elastic member 140 can abut against the inner wall of the protrusion 132 (i.e., the inner wall of the protrusion 132 that is away from the support rod 120 and is in a recessed structure), thereby limiting the second end of the first elastic member 140 and making the abutment between the first elastic member 140 and the cover 130 more stable.

[0077] Optionally, the first elastic member 140 is a torsion spring, so that the first elastic member 140 can be sleeved on the second pin shaft 125 and is not easily separated.

[0078] Optionally, refer to Figure 8The support plate device includes two first elastic members 140, and two first elastic members 140 are correspondingly arranged for one second pin shaft 125, and the two first elastic members 140 are arranged along the axial direction of the second pin shaft 125 and are located at both ends of the second pin shaft 125. The two first elastic members 140 apply elastic force to the cover 130, which can not only ensure that the cover 130 can be subjected to sufficient elastic force, but also prevent the failure of a single first elastic member 140 to cause the cover 130 to fail to cover the opening 101.

[0079] Furthermore, the first end of the first elastic member 140 may be optionally passed through the connecting portion 121, so that the first end of the first elastic member 140 is fixed relative to the supporting rod 120. The second ends of the two first elastic members 140 located on the same second pin shaft 125 are connected together, so that the abutment effect of the two first elastic members 140 on the second pin shaft 125 on the cover 130 is more consistent.

[0080] Optionally, the support plate device may also include more than two first elastic components 140 , and one second pin shaft 125 may be provided with more than two first elastic components 140 , which may also ensure the abutment effect on the cover 130 .

[0081] Reference Fig. 9 and Fig.10 In order to shield the opening 101 from the outside of the seat back plate 100, the support plate device can also be configured to include a shielding curtain 150. The first end of the shielding curtain 150 is connected to the support plate 110, and the second end of the shielding curtain 150 extends to the bottom of the seat and is fixed to the inner side of the seat back plate 100. Fig. 9 It can be seen that when the support rod 120 is in the retracted position, the support plate 110 is retracted into the chair back plate 100, and the shielding curtain 150 shields the opening 101 of the seat, thereby preventing foreign objects from entering the opening 101 and making the seat more beautiful. The shielding curtain 150 can be made of leather or rubber material. When the support rod 120 is in the extended position, the support plate 110 can be moved and extended without being interfered by the shielding curtain 150.

[0082] The utility model also discloses a seat, comprising a seat body and a support plate device according to the above. The seat body is provided with an opening 101. The support plate 110 is located outside the opening 101 of the seat body, the first end of the support rod 120 is connected to the support plate 110, and the second end of the support rod 120 extends into the seat body through the opening 101. According to the seat of the utility model, when the support plate 110 on the seat is unfolded by the drive of the support rod 120, the cover 130 abuts against the edge of the opening 101 of the seat under the elastic force of the first elastic member 140, so that the cover 130 covers the opening 101 of the seat, which not only makes the seat more beautiful, but also prevents foreign matter from entering the opening 101 and causing seat failure.

[0083] The utility model also provides a vehicle, comprising the seat according to the above. According to the vehicle of the third aspect of the utility model, the seat of the vehicle has a support plate device, and the opening 101 formed by the setting of the support plate device can be covered after the support plate 110 is unfolded, which is not only beautiful but also can reduce the failure rate of the seat.
