[0041] According to some embodiments of the present application, please refer to Figures 1 to 5 The present embodiment relates to a vehicle-mounted sofa bed, comprising a seat cushion 1, a backrest 2, a support member 3 and a driving mechanism 4, wherein a seat cushion bracket 11 is provided on the seat cushion 1, the seat cushion 1 is located at the front end of the backrest 2, the backrest 2 is connected to one side of the seat cushion 1, a backrest bracket 21 is provided on the backrest 2, and the backrest bracket 21 is hinged to one end of the seat cushion bracket 11; the support member 3 is installed at the rear end of the backrest 2, one end of the support member 3 is hinged to the backrest 2, and the other end of the support member 3 is hinged to the bottom of the car; the driving mechanism 4 is transmission-connected with the seat cushion bracket 11, the driving mechanism 4 is used to drive the seat cushion bracket 11 to move horizontally forward away from one end of the support member 3, and at the same time, the seat cushion bracket 11 drives the backrest 2 to move horizontally forward, and the backrest 2 rotates counterclockwise, and the driving mechanism 4 is used to drive the seat cushion bracket 11 to move horizontally backward close to one end of the support member 3, and at the same time, the seat cushion bracket 11 pushes the backrest 2 to move horizontally backward, and the backrest 2 rotates clockwise.

[0042] The seat cushion 1 and the backrest 2 in the prior art cannot move at the same time, and the position of the backrest 2 can only be adjusted after the seat cushion 1 is adjusted to the corresponding position. There is a certain distance between the backrest 2 and the seat cushion 1. The technical solution of the present application designs the backrest 2 and the seat cushion 1 as one body, shortening the distance between the seat cushion 1 and the backrest 2. When the seat cushion 1 moves, the backrest 2 will also move accordingly, and a support member 3 is added behind the backrest 2, one end of the backrest 2 is hinged to the seat cushion 1, and the other end of the backrest 2 is hinged to the support member 3. When in use, a person can sit on the seat cushion 1, and the driving mechanism 4 can be equipped with a remote control to facilitate the person to start the driving mechanism 4. The driving mechanism 4 is connected to the seat cushion bracket 11 for transmission. When the driving mechanism drives the seat cushion bracket 11 to move forward horizontally, it has a pulling force on the backrest 2, thereby generating a certain force on the support member 3. During the forward movement, the backrest 2 gradually falls backward, so that the backrest 2 is flattened relative to the seat cushion 1. The support member 3 is hinged to the bottom of the car, so that the support member 3 can adjust the angle according to the rotation of the backrest 2 and support the backrest 2 at the same time. After use, the driving mechanism 4 can be controlled to drive the seat cushion bracket 11 to move backward horizontally, and the backrest 2 moves backward accordingly and gradually rises, so that the backrest 2 is upright relative to the seat cushion 1, and the support member 3 adjusts the angle to support the backrest 2.

[0043] According to some embodiments of the present application, optionally, a positioning frame 7 is provided on one side of the seat cushion bracket 11 close to the backrest 2 , the height of the positioning frame 7 matches the height of the seat cushion bracket 11 , and the positioning frame 7 is used to fix the seat cushion bracket 11 .

[0044] In this way, when the driving mechanism 4 drives the cushion bracket 11 to move to the position of the positioning frame 7 close to one end of the support member 3, the positioning frame 7 and the cushion bracket 11 are engaged with each other, and the backrest 2 and the seat cushion 1 are relatively fixed, thereby reducing the shaking of the backrest 2.

[0045] The positioning frame 7 can be made of wood or metal and is set at the bottom of the backrest bracket 21. The driving mechanism 4 drives the seat cushion bracket 11 to move horizontally backward for a certain distance and will contact the positioning frame 7, so that the seat cushion bracket 11 can no longer move.

[0051] In this way, when the cushion bracket 11 moves close to one end of the positioning frame 7, the positioning portion 1131 does not need to be accurately docked with the positioning groove 71 at one time. The bottom of the positioning portion 1131 passes through a certain arc and gradually engages with the arc-shaped snap-fitting opening 711, and finally the positioning groove 71 is docked with the positioning portion 1131. The arc-shaped snap-fitting opening 711 increases the probability of successful docking.

[0052] The driving mechanism 4 drives the cushion bracket 11 to move horizontally backward and approach the positioning frame 5. During the docking process, errors are prone to occur due to position adjustment. The arc-shaped snap-fitting opening 511 improves the effectiveness of the docking, and the bottom of the positioning portion 1131 can gradually extend into the arc-shaped snap-fitting opening to form a snap-fitting structure.

[0053] According to some embodiments of the present application, optionally, the driving mechanism 4 includes a driving motor 41, a screw 42 and a screw nut 43, the driving motor 41 is installed at the bottom of the seat cushion bracket 11, the screw 42 is located at the bottom of the seat cushion bracket 11, the screw 42 is transmission connected to the driving motor 41, the screw nut 43 is threadedly transmission connected to the screw 42, and the screw nut 43 is fixedly connected to the seat cushion bracket 11.

[0054] In this way, the drive motor 41 is started, the screw rod 42 rotates, and the screw nut 43 moves horizontally on the screw rod 42, thereby driving the seat cushion bracket 11 and the backrest 2 to move forward or backward, so that the backrest 2 is flattened or upright relative to the seat cushion 1.

[0055] A fixing plate may be provided at the bottom of the cushion bracket 11 , and one end of the screw rod 42 may be fixed on the fixing plate.

[0056] The driving motor 41 drives the screw rod 42 to rotate clockwise, and the screw nut 43 moves horizontally forward on the screw rod 42, driving the cushion bracket 11 to move horizontally forward toward the end away from the support member 3, and the cushion bracket 11 drives the backrest 2 to move forward, and the backrest 2 rotates counterclockwise. It can rotate a certain angle according to actual needs. When the backrest 2 rotates to be flat relative to the cushion 1, the counterclockwise rotation angle is the largest. The driving motor 41 drives the screw rod 42 to rotate counterclockwise, and the screw nut 43 moves horizontally backward on the screw rod 42, driving the cushion bracket 11 to move horizontally toward the end close to the support member 3, and the cushion bracket 11 pushes the backrest 2 to move backward, and the backrest 2 rotates clockwise. It can rotate a certain angle according to actual needs. When the backrest 2 rotates to be upright relative to the cushion 1, the clockwise rotation angle is the largest.
