Embodiment Construction

[0022] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the implementation of the present invention will be further described below in conjunction with specific illustrations.

[0023] see figure 2 and image 3 , the seat electric lift adjustment device with a damping structure shown in the figure includes a drive motor 100, a reduction box body 200, a reduction box cover 300 and a reduction mechanism. The drive motor 100 is a DC motor, the reduction box body 200 is a plastic part, and the reduction box cover 300 is a metal part.

[0024] The reduction box body 200 and the reduction box cover 300 define an installation cavity, which includes a worm accommodation cavity 210 and a planetary reduction member accommodation cavity 220, the axis of the planetary reduction component accommodation cavity 220 is perpendicular to the axis of the worm accommodation cavity 210, And the top of the planetary ...

Abstract

The invention discloses a seat electric lifting adjusting device provided with a damping structure. The seat electric lifting adjusting device provided with the damping structure comprises a reducer box body, a reducer box cover, a driving motor and a reducing mechanism. A planetary reduction mechanism in the reducing mechanism comprises a geared ring board, a planet carrier transmission component, a sun gear and a plurality of planet wheels. The planet carrier transmission component comprises a wheel disc, a lifting adjusting gear and a shaft part, wherein the wheel disc and the lifting adjusting gear are arranged coaxially, and the shaft part and the lifting adjusting gear are coaxially arranged between the wheel disc and the lifting adjusting gear. A center hole is formed in the center of the reducer box cover. An outward flanging which at least contains part of the shaft part is arranged on the periphery of the center hole. A volute-roll spring is wound on the shaft part to provide friction torque for the planetary reduction mechanism. The extremely large friction torque is generated to the planet carrier transmission component by the volute-roll spring of the seat electric lifting adjusting device provided with the damping structure, rotational speed of the planet carrier transmission component can be largely reduced, and therefore speed during descending of the seat is reduced, and the goal that speed difference of the ascending direction and the descending direction is reduced is achieved.

Description

technical field [0001] The invention relates to the technical field of seats, in particular to the technical field of car seats, in particular to an electric seat lift adjustment device with a damping structure. Background technique [0002] The lifting adjustment devices used in passenger car seats are generally divided into two types: electric or manual, according to different configuration requirements of users. Seat electric lift adjustment devices currently on the market mainly use a motor-driven reduction box system to enable the driver or passenger to achieve a comfortable seating position. [0003] DE10 2004 040602A1 discloses an electric lifting adjustment device in which a planetary reduction mechanism is driven by a drive motor through a worm gear transmission mechanism. The worm gear transmission mechanism and the planetary reduction mechanism are installed in the installation cavity defined by the reduction box body and the reduction box cover. , The worm in th...
