Electric turnover device for automobile rear seats

Abstract

The invention provides an electric turnover device for automobile rear seats. The electric turnover device for the automobile rear seats comprises a turnover assembly fixedly connected with an automobile seat; a drive assembly connected to the turnover assembly and used for driving the turnover assembly to rotate, and a support mechanism bracket of the drive assembly. The electric turnover devicefor the automobile rear seats reduces the high rotational speed of a direct current motor to achieve the target rotational speed of seat turnover by adopting the worm helical gear transmission and thespur gear transmission to form a secondary transmission mechanism. As the weight of the rear seats of the automobile is large, the prior art only play a power-assisting role in manual turnover. The electric turnover device realizes the liberation of hands, completely saves labor, and improves the operability of the automobile seat accessories and the convenience and comfort when the seats are used.

Description

technical field [0001] The invention relates to an electric turning device for rear seats of an automobile. Background technique [0002] The seat flips up to make efficient use of the car's interior space. The flipping form of the rear seat of the car is to put the seat back down, the backrest is close to the seat cushion, and finally the whole seat is flipped into the trough of the trunk of the car. In order to realize the storage of the rear seats of the car and increase the storage space of the car. Because the gravity of the car seat will generate a resistance moment during the turning process of the car seat, in order to overcome the resistance moment, the existing rear seat turning mechanism is to reduce the operating force of the seat turning in a power-assisted manner. To the role of labor-saving. [0003] Existing overturning booster mechanisms such as Patent Publication No. CN201710453353 disclose a kind of overturning booster device, which realizes the role of...

Problems solved by technology

[0003] Existing overturning booster mechanisms such as Patent Publication No. CN201710453353 disclose a kind of overturning booster device, which realizes the role of boosting in the process of seat overturning through its internal elastic parts, and because the seat overturning booster mechanism is in the process of seat overturning , since the assisting torque is smaller than the resistance torque generated by gravity, it is necessary to manually drag the seat to reach the flip position; secondly, the flipping of the seat requires manual pulling, and the human hand still needs to apply force to the seat, the operation is cumbersome and cannot be completely labor-saving ; Again, the seat flip assist device, due to a large number of parts, production and assembly are more complicated
