The aforementioned solution enables convenient and quick opening and closing of the car seat backrest 101, improving user convenience.

[0021] In this specific embodiment, the two transmission components 102 are located on both sides of the back plate 101; each transmission component 102 includes a connecting part 106, two transmission parts 107, and a mounting plate 108. The connecting part 106 is disposed on the side of the back plate 101, the two transmission parts 107 are disposed on both sides of the connecting part 106, and the mounting plate 108 is disposed on the side of the two transmission parts 107; the cylinder 103 is fixedly connected to the mounting plate 108 and is located on the side of the mounting plate 108; the rack 104 is fixedly connected to the output rod of the cylinder 103 and is located on the side of the cylinder 103; the gear 105 is disposed on the side of the connecting part 106 and meshes with the rack 104. The mounting plate 108 is installed on the car seat. The mounting plate 108 and the transmission component 102 provide support for the back panel 101. Storage space is provided in the seat back. By controlling the output rod of the cylinder 103 to retract, the cylinder 103 drives the rack 104 to move, and the rack 104 drives the gear 105 to rotate. Under the transmission of the transmission component 107, the connecting part 106 and the back panel 101 flip outwards, revealing the storage space in the seat back. The user can place items in the storage space in the seat back. After the items are placed... The output rod of the cylinder 103 extends, and under the transmission of the rack 104, the gear 105, and the transmission unit 107, the back panel 101 flips inward to fit against the back of the car seat, sealing the storage space of the seat back and preventing items from falling out. The cylinder 103 is a mature existing technology, and the solenoid valve in the air circuit of the cylinder 103 can be controlled by an electric switch button to control the operation of the cylinder 103 and realize the opening and closing of the back panel 101. This utility model can conveniently and quickly open and close the car seat back panel 101, improving the convenience for users.

[0022] The two connecting seats 109 are respectively disposed on the sides of the two transmission parts 107; the connecting plate 110 is fixedly connected to the two connecting seats 109 and is located on the sides of the two connecting seats 109; the spring 111 is fixedly connected to the connecting plate 110 and is located inside the connecting plate 110; the limiting block 112 is fixedly connected to the spring 111 and is located on the side of the spring 111. First, the limiting block 112 is pulled away from the connecting plate 110, at which time the spring 111 is stretched. Then, the back plate 101 is placed on the connecting plate 110, and the limiting block 112 is released. The limiting block 112 moves to the surface of the back plate 101 under the action of the spring 111, and the back plate 101 is installed on the connecting plate 110.

[0023] Secondly, the two positioning blocks 113 are respectively fixedly connected to the connecting plate 110 and are located on the side of the connecting plate 110. The back plate 101 has two positioning slots 114, which are located on the side of the back plate 101 near the connecting plate 110. The positioning slots 114 are adapted to the positioning blocks 113. First, pull the limiting block 112 away from the connecting plate 110, then place the back plate 101 on the connecting plate 110, so that the positioning block 113 is inserted into the positioning slot 114. Then, release the limiting block 112, which moves to the surface of the back plate 101 under the action of the spring 111. The positioning block 113 and the limiting block 112 fix the position of the back plate 101, thereby installing the back plate 101 on the connecting plate 110. This fixing method makes it easy to disassemble and replace the back plate 101.

[0024] Simultaneously, the rotating shaft 115 is rotatably connected to the mounting plate 108 and located on the side of the mounting plate 108; the connecting arm 116 is fixedly connected to the rotating shaft 115 and located on the side of the rotating shaft 115; one end of the rotating arm 117 is rotatably connected to the connecting arm 116, and the other end is rotatably connected to the connecting seat 109 and located between the connecting arm 116 and the connecting seat 109. The output rod of the cylinder 103 is extended, causing the cylinder 103 to drive the rack 104 to translate, which in turn drives the gear 105 and the rotating shaft 115 to rotate. The rotating shaft 115 then drives the connecting arm 116 and the rotating arm 117 to rotate, and the rotating arm 117 drives the connecting seat 109, the connecting plate 110, and the back plate 101 to rotate, thus achieving the flipping of the back plate 101.

[0025] In using this utility model, the mounting plate 108 is installed on a car seat. The mounting plate 108 and the transmission component 102 provide support for the back panel 101. Storage space is provided in the seat back. By controlling the output rod of the cylinder 103 to retract, the cylinder 103 drives the rack 104 to move. The rack 104 drives the gear 105 to rotate. The rotating shaft 115 drives the connecting arm 116 and the rotating arm 117 to rotate. The rotating arm 117 drives the connecting seat 109, the connecting plate 110, and the back panel 101 to rotate. The movement causes the back panel 101 to flip outward, revealing the storage space on the back of the seat, where the user can place items. After the items are placed, the output rod of the cylinder 103 extends, and under the transmission of the rack 104, the gear 105, the connecting arm 116, and the rotating arm 117, the back panel 101 flips inward to fit against the back of the car seat, sealing the storage space and preventing items from falling out. This invention allows for convenient and quick opening and closing of the car seat back panel 101, improving user convenience.
