The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0030] See also Figures 1 to 6 The embedded hidden bracket of the utility model is applied to the backrest 1 of the vehicle seat. The embedded hidden bracket includes a frame 2, a connecting rod structure 3 connected to the frame 2, and a support plate 4 connected to the connecting rod structure 3. The frame 2 is embedded in the back of the backrest 1. The connecting rod structure 3 is symmetrically arranged on the two opposite inner sides of the frame 2 to improve the stability of the connection between the frame 2 and the support plate 4. In this embodiment, a fixing groove adapted to the frame 2 is opened in the middle position of the back of the backrest 1 of the vehicle seat. The groove depth range of the fixing groove can be set to 30mm-50mm. As a specific example, the groove depth of the fixing groove in this embodiment is 40mm. The frame 2 is embedded in the fixing groove and fixed inside the fixing groove by fasteners such as screws. A receiving groove 21 for receiving the support plate 4 is arranged in the frame 2.

[0031] As an example, the connecting rod structure 3 includes a pull rod 31, and the pull rod 31 is used to connect the frame 2 and the support plate 4. Specifically, Figure 4 As shown, one end of the tie rod 31 is rotatably connected to the side wall of the frame 2, and the other end of the tie rod 31 is rotatably connected to the side of the support plate 4 to realize the movable connection between the support plate 4 and the frame 2. In actual use, the two sides of the support plate 4 are movably connected to the two opposite inner sides of the frame 2 through the two tie rods 31. Since the connection mode of both ends of the tie rod 31 is a rotatable connection, the use angle of the support plate 4 can be changed under the action of the tie rod 31. It should be noted that the two ends of the tie rod 31 are respectively provided with connection holes, and the distance between the two connection holes ranges from 130mm to 140mm. As a specific example, in this embodiment, the distance between the connection holes at both ends of the tie rod 31 is 138mm.

[0032] Furthermore, in order to fix the use angle of the support plate 4 to meet the use requirements of the passengers, the connecting rod structure 3 in the utility model further includes a support rod 32, and the support rod 32 is used to limit the position of the pull rod 31. Specifically, as Figures 4 to 6 As shown, the support rod 32 includes a connecting portion 321 and a supporting portion 322 extending outward from the connecting portion 321. In the present embodiment, the support rod 32 is arranged on the side of the pull rod 31 away from the top end of the chair back 1. The connecting portion 321 is rotationally connected to the side wall of the frame 2, and the supporting portion 322 is rotationally connected to the side edge of the support plate 4. A supporting end surface 323 is provided on the side of the support portion 322 opposite to the pull rod 31. The supporting end surface 323 is used to abut against the side edge of the pull rod 31 to limit the position of the pull rod 31, thereby achieving the purpose of fixing the use angle of the support plate 4. In actual use, the support rod 32 and the pull rod 31 can be completely hidden and accommodated in the accommodating groove 21 of the frame 2 or fixedly displayed on the outside of the frame 2 under the action of external force. When the pallet 4 is accommodated in the accommodating groove 21, in the height direction of the chair back 1, the connection between the pull rod 31 and the side wall of the frame 2 is higher than the connection between the connecting part 321 of the support rod 32 and the side wall of the frame 2, and the connection between the pull rod 31 and the side of the pallet 4 is higher than the connection between the supporting part 322 of the support rod 32 and the side of the pallet 4.

[0033] Furthermore, if Figure 6 As shown, the angle b between the side of the support portion 322 opposite to the support end face 323 and the connecting portion 321 is set as an obtuse angle to improve the supporting stability of the support rod 32 on the pull rod 31. The range of the angle b is 145°-155°. As a specific example, in this embodiment, the angle b is 150°.

[0034] When the pull rod 31 abuts against the support end surface 323 on the support rod 32, the position of the pull rod 31 is restricted. Figure 4 As shown, the position of the support plate 4 is fixed and located outside the frame 2. At this time, the angle a between the plane direction of the support plate 4 and the vertical direction ranges from 80° to 90°. As a specific example, in this embodiment, the angle a between the support plate 4 and the ground is the best use angle of 85°, which maximizes the user experience of the occupants.

[0035] The embedded hidden bracket of the utility model is also provided with a locking structure 5, which is used to improve the connection stability between the support plate 4 and the frame 2 to prevent the support plate 4 from being separated from the frame 2 when not in use. In this embodiment, the locking structure 5 includes a locking plate 51 and a locking hole 52 adapted to the locking plate 51. The frame 2 is provided with a locking plate 51 on the side close to the top of the chair back 1, and the support plate 4 is provided with a locking hole 52. Specifically, when the support plate 4 is accommodated in the receiving groove 21 of the frame 2, the support plate 4 is provided with a locking hole 51 on the side close to the top of the chair back 1, and the frame 2 is provided with a locking plate 52 on the side close to the top of the chair back 1. The locking plate 52 is a knob-type locking plate. When the knob-type locking plate is screwed into the locking hole 52 on the support plate 4 located in the receiving groove 21 under the action of an external force, the support plate 4 is locked and fixed in the receiving groove 21.

[0036] Furthermore, a mounting groove (not shown) is provided on one side of the pallet 4, in which an external keyboard 6 is installed, and a plurality of handle grooves 41 are provided on the other side of the pallet 4. As a specific example, in this embodiment, when the pallet 4 is accommodated inside the frame 2, the inner surface of the pallet 4, that is, the side opposite to the inner wall of the fixing groove on the chair back 1, is provided with the mounting groove, and the outer surface of the pallet 4, that is, the side opposite to the inner wall of the fixing groove on the chair back 1, is provided with two handle grooves 41 at the end close to the top of the chair back 1.

[0037] It should be noted that the support plate 4 in the present invention is generally formed by milling, and through the design of reserved installation slots, it can meet the installation requirements of external keyboards of different specifications, thereby greatly improving the applicability of the support plate 4.

[0038] In actual use, the use principle of the embedded hidden bracket of the utility model is as follows: Figures 1 to 3 As shown, the knob-type locking piece 51 is first operated, and the locking piece 51 is disengaged from the locking hole 52 on the support plate 4, so that the locking piece 51 is completely accommodated in the frame 2 to prevent the locking piece 51 from affecting the removal of the support plate 4 from the receiving groove 21. Then, the support plate 4 is lifted and the use angle is adjusted through the handle groove 41 on the support plate 4. In this process, the partial rod body of the pull rod 31 connected to both sides of the support plate 4 and the supporting part 322 of the support rod 32 gradually move away from the receiving groove 21, and the angle between the pull rod 31 and the support rod 32 also changes accordingly. When the rod body of the pull rod 31 abuts against the supporting end surface 323 on the support rod 32, the position of the pull rod 31 is restricted, and the side of the support plate 4 with the keyboard 6 installed is arranged toward the top of the seat back 1, and the angle between the support plate 4 and the ground is fixed, so that the keyboard is presented to the occupant at the best operating angle of 85°, improving the occupant's use experience.

[0039] When the keyboard 6 is not in use, the support plate 4 can be operated to be hidden in the receiving groove 21 of the frame 2. Specifically, the support plate 4 is lifted by the handle groove 41 on the support plate 4, and the support plate 4 is gradually pushed back into the receiving groove 21 by the deadweight of the support plate 4, the pull rod 31 and the support rod 32. When the support plate 4 is completely located in the receiving groove 21, that is, Figure 1 As shown, the knob-type locking piece 51 on the frame 2 is then operated to insert the locking piece 51 into the locking hole 52 on the support plate 4, thereby achieving locking and fixing between the frame 2 and the support plate 4.

[0040] In summary, the beneficial effect of the embedded hidden bracket of the utility model is that by embedding a frame in the seat back and providing a receiving groove for accommodating the pallet in the frame, the pallet can be stored and hidden when not in use, avoiding the compression of the space between the front and rear seats when the pallet is not in use, improving the riding comfort of the vehicle occupants, and not affecting the occupants' emergency leaving actions. Furthermore, by providing a connecting rod structure between the frame and the pallet, an active connection between the frame and the pallet is achieved, the convenience of storing the pallet when not in use is improved, and the pallet can be fixed in front of the occupants at a better use angle when in use, thereby improving the occupants' use experience. In addition, a mounting groove is provided on the pallet, and the setting of the mounting groove can fix the external keyboard, improve the stability of the external keyboard, and avoid the problem of swaying during the use of the external keyboard, which affects the work efficiency of the occupants. In addition, the mounting groove can also be installed with external keyboards of different specifications, greatly improving the applicability of the embedded hidden bracket of the utility model.
