Description

Technical Field

[0001] The present invention belongs to the technical field of vehicle seats, and particularly relates to a folding and sunken storage seat. Background Art

[0002] A vehicle seat is a seat for passengers when riding in a vehicle. Traditional vehicle seats usually adjust the space by simple folding or sliding rail translation. However, after folding, the seat still occupies a certain height and is difficult to be completely hidden on one side of the vehicle body. Some vehicle models adopt a sunken storage design, but there are problems such as complex structure, cumbersome operation, and insufficient stability. Therefore, the present invention proposes a folding and sunken storage seat to solve the above problems. Summary of the Invention

[0003] The present invention provides a folding and sunken storage seat, aiming to solve the problems raised in the background art.

[0004] The present invention is implemented as follows. A folding and sunken storage seat includes a seat cushion assembly, a backrest assembly, a support frame, a recliner assembly, a slide rail assembly, and a frame.

[0005] The seat cushion assembly includes a seat cushion frame. Left and right seat cushion side plates are respectively arranged on the left and right sides of the seat cushion frame, and the left and right seat cushion side plates are used to provide support force for the seat cushion frame.

[0006] The backrest assembly includes a headrest guide sleeve frame and a backrest U-shaped tube. Two relatively distributed headrest guide sleeve frames are arranged on the backrest U-shaped tube. A headrest guide sleeve is arranged on the headrest guide sleeve frame, and a headrest rod is arranged on the headrest guide sleeve. Left and right side plates are respectively arranged on the left and right sides of the backrest U-shaped tube.

[0007] The recliner assembly includes a backrest recliner assembly and a seat cushion recliner assembly. The upper ends of the bottoms of the left and right side plates are connected to the seat cushion recliner assembly, and the lower ends of the bottoms of the left and right side plates are connected to the backrest recliner assembly. The backrest recliner assembly is connected to a left support frame and a right support frame. The left side plate and the left support frame are connected through the recliner assembly, and the right side plate and the right support frame are connected through the recliner assembly.

[0008] The slide rail assembly is connected to the left support frame and the right support frame, and is fixedly connected to the frame. The slide rail assembly is used to drive the seat cushion frame to move up and down.

[0009] Preferably, both the left and right seat cushion side plates are of L-shaped structure.

[0010] Preferably, it further includes a backrest motor and a seat cushion motor. The backrest motor is used to drive the backrest angle adjuster assembly to drive the backrest assembly to rotate, and the seat cushion motor is used to drive the seat cushion angle adjuster assembly to drive the seat cushion assembly to rotate.

[0011] Preferably, it further includes a panel and a seat control module. The panel is fixedly arranged at the lower end of the slide rail in the slide rail assembly, and the seat control module is fixedly arranged on the panel.

[0012] Preferably, when the seat is in the unfolded working state, the seat cushion frame is horizontally set through the operation of the seat cushion angle adjuster assembly and the seat cushion motor, and then the slide rail assembly starts to drive the seat cushion frame to lift. Then, the backrest assembly realizes a backward tilt of 5-7° through the operation of the backrest angle adjuster assembly and the backrest motor.

[0013] Preferably, when the seat is in the folded and sunken state, the seat cushion frame realizes an upward flip of 95° through the operation of the seat cushion angle adjuster assembly and the seat cushion motor. Synchronously, the backrest assembly realizes a forward tilt of 5-7° through the operation of the backrest angle adjuster assembly and the backrest motor. Then, the slide rail assembly starts to drive the seat cushion frame to sink.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. When the seat is in the unfolded working state, the seat cushion frame is horizontally set through the operation of the seat cushion angle adjuster assembly and the seat cushion motor, and then the slide rail assembly starts to drive the seat cushion frame to lift, that is, the slide rail assembly enters the motion state and drives the seat cushion frame to move upward to the top. Then, the backrest assembly realizes a backward tilt of 5-7° through the operation of the backrest angle adjuster assembly and the backrest motor.

[0016] 2. When the seat is in the folded and sunken state, the seat cushion frame realizes an upward flip of 95° through the operation of the seat cushion angle adjuster assembly and the seat cushion motor. Synchronously, the backrest assembly realizes a forward tilt of 5-7° through the operation of the backrest angle adjuster assembly and the backrest motor. Then, the slide rail assembly starts to drive the seat cushion frame to sink, that is, after the seat cushion frame flips upward by 95°, the slide rail assembly enters the motion state and drives the seat cushion frame to move downward to the end, realizing the folding and sunken function of the whole seat; the folding and sinking of the whole seat solves the problem of improving the space utilization rate of the car. An electric drive folding and sinking mechanism is adopted, and users can easily realize the storage and unfolding operations of the seat only through the in-vehicle control panel or the remote control device.

[0017] 3. In the present invention, the left side plate and the right side plate are provided to integrate both the backrest angle adjuster assembly and the seat cushion angle adjuster assembly on the side plates. Such an integrated structure is a double-rotation structure, which can not only meet the strength requirements but also optimize the internal space of the seat. BRIEF DESCRIPTION OF THE DRAWINGS
