Description

Technical Field

[0001] The invention relates to the technical field of automobile seats, and in particular to a folding automobile seat and a control method thereof. Background Art

[0002] Car seats are an important part of car interiors, providing drivers and passengers with convenient operation, comfortable and safe driving experience. Car seats installed in commercial vehicles are generally divided into three rows, distributed in the front, middle and rear of the car.

[0003] Existing car seats are generally folded by flipping the backrest forward to a limit position and contacting the seat cushion. This folding method does not reduce the space occupied by the folded car seat, and the slide rails of the middle and rear row car seats are set separately, which makes it impossible for the middle row seats to move to the rear cabin. Therefore, the space in the car compartment is not increased after the car seats are folded and stowed, and the folding effect is poor.

[0004] For this reason, it is necessary to design a kind of automobile folding seat and control method to solve the problem. Summary of the invention

[0007] Furthermore, the two driving modules 1 and 2 are electrically controlled and connected to an external seat control switch.

[0008] Furthermore, the driving module 1 includes a driving motor 1, which is fixedly installed on one side of the inner side of the seat basin. The output ends of the driving motor 1 are transmission-connected with a transmission shaft, and the transmission shaft does not pass through the seat basin and is fixedly connected to a recliner 1.

[0009] Furthermore, the driving module 2 includes a driving motor 2 fixed on one side of the inner part of the backrest frame and a recliner 3 fixed on both sides of the lower part of the upper frame of the folding backrest, the two recliners 3 are in contact and overlap with the two recliners 2, and are connected with a connecting shaft, the connecting shaft is fixedly connected to the recliner 3 and rotatably connected to the recliner 2, and the connecting shaft is transmission-connected to the output end of the driving motor 2.

[0010] Furthermore, the two driving modules can be driven synchronously to drive the seat basin to flip and fold 90 degrees to a limit position.

[0011] Furthermore, the driving module 2 can drive the upper frame of the folding backrest to flip and fold 90 degrees to a limit position.

[0012] A method for controlling a folding seat of an automobile, characterized in that the sliding seat, the vehicle seat body, the seat basin and the backrest frame constitute a folding seat, the folding seat is divided into two rows and installed in the middle and rear of the automobile, the two rows of folding seats share the same sliding seat, the two rows of folding seats can be folded and stored to the rear of the automobile through program control of an external seat control switch, and the folding and storing comprises the following steps:

[0013] S1. First, fold up the rear folding seat of the vehicle: synchronously control two drive modules 1 through the seat control switch to drive the seat basin to flip upward 90 degrees and fold it to contact the backrest frame, and at the same time control drive module 2 to drive the upper frame of the folding backrest to flip downward 90 degrees and fold it;

[0014] S2, folding and stowing the middle row of folding seats in the car: synchronously controlling two drive modules 1 through the seat control switch to drive the seat basin to flip upward 90 degrees and fold it to contact the backrest frame, and at the same time controlling drive module 2 to drive the upper frame of the folding backrest to flip downward 90 degrees and fold it;

[0015] S3. Finally, the folded middle row folding seats are pushed toward the rear cabin by the sliding seat to be close to the folded rear row folding seats, thereby increasing the space for people in the middle cabin of the car.

[0016] Compared with the related art, the automobile folding seat and control method provided by the present invention have the following beneficial effects:

[0017] The present invention provides a method of synchronously controlling two drive modules through a seat control switch to drive one drive module to drive the seat basin to flip upward by 90 degrees and fold it to contact the backrest frame, and at the same time controlling a second drive module to drive the upper frame of the folding backrest to flip downward by 90 degrees and fold it, and then folding and stowing the middle row of folding seats in the same way, and finally pushing the folded middle row of folding seats to move to the rear cabin and close to the folded rear row of folding seats through a sliding seat, thereby increasing the space for people in the middle cabin of the car and facilitating people to have enough space to move around.

[0023] Embodiment 1, by Figure 1-4 A folding car seat is provided, comprising a seat body 2 which is slidably mounted on a slide rail 1, with recliners 62 symmetrically fixed on both sides of the top of the seat body 2, a seat basin 3 being arranged between the two recliners 62, two sets of drive modules 1 being symmetrically arranged between the seat body 2 and the seat basin 3 for transmission connection, a backrest frame 4 being mounted on the rear of the seat body 2, recliners 71 being fixed on both sides of the upper part of the backrest frame 4, a drive module 2 being arranged between the two recliners 71, a folding backrest upper frame 5 being transmission-connected via the drive module 2, and the two drive modules 1 and the drive module 2 being electrically controlled and connected to an external seat control switch.

[0024] Specifically, first, the rear folding seats of the car are folded and stowed: the two drive modules are synchronously controlled by the seat control switch to drive the seat basin 3 to flip upward 90 degrees and fold it into contact with the backrest frame 4, and the drive module 2 is controlled to drive the upper frame 5 of the folding backrest to flip downward 90 degrees and fold it; the middle row of folding seats of the car are folded and stowed: the two drive modules are synchronously controlled by the seat control switch to drive the seat basin 3 to flip upward 90 degrees and fold it into contact with the backrest frame 4, and the drive module 2 is controlled to drive the upper frame 5 of the folding backrest to flip downward 90 degrees and fold it; finally, the folded middle row of folding seats are pushed to the rear cabin by the sliding seat 1 to move close to the folded rear row of folding seats, thereby increasing the space for people in the middle cabin of the car.

[0025] In this embodiment, the driving module 1 includes a driving motor 16, which is fixedly installed on one side of the seat basin 3. The output ends of the driving motor 16 are connected to the transmission shaft 61, and the transmission shaft 61 does not penetrate the seat basin 3 and is fixedly connected to the angle adjuster 162 respectively. The synchronous driving of the two driving modules 1 can drive the seat basin 3 to flip and fold ninety degrees to the limit position; the driving of the driving motor 16 is synchronously controlled by the seat control switch. Since the two driving motors 16 are fixed on the backrest frame 4 and the two transmission shafts 61 are fixed on the transmission shaft 61, the driving motor 16 and the transmission shaft 61 drive the seat basin 3 to flip upward ninety degrees and fold it to contact the backrest frame 4.

[0026] In this embodiment, the driving module 2 includes a driving motor 2 7 fixed on one side of the backrest frame 4 and a recliner 3 73 fixed on both sides of the lower part of the upper frame 5 of the folding backrest.
