Direct-drive type manual half-basin lifting device for automobile seat

Abstract

The invention belongs to the technical field of automobile manufacturing, and discloses a direct-drive type manual half-basin lifting device for an automobile seat. The direct-drive type manual half-basin lifting device comprises a box cover, a gear ring, a gear, a sliding block, an eccentric shaft and a box body; the box cover is connected with the box body in a fastened mode, the input end of the eccentric shaft is inserted into a center hole of the box body, the gear ring is mounted at the output end of the eccentric shaft, and the output end of the gear ring penetrates through the box cover; and a sliding groove is formed in the box body, the eccentric shaft is sleeved with the sliding block, the sliding block can slide in the sliding groove, an eccentric wheel of the eccentric shaft is sleeved with the gear, the gear is provided with a boss, and the boss is inserted in a transverse groove formed in the sliding block. According to the direct-drive type manual half-basin lifting device for the automobile seat, the structure is simple, and the strength is high; the direct-drive type structure is adopted, the output end of the lifting device directly drives a half-basin connectingrod, the lifting function is achieved, and the defect that stability of a gear tooth plate type structure is poor is overcome; and after speed reducing and torque increasing through a few tooth difference type gear with large transmission ratio are conducted, operating force is smaller compared with the gear tooth plate type, and operating comfort of the seat is improved.

Description

technical field [0001] The invention belongs to the technical field of automobile manufacturing, and relates to a manual half-basin lifting device for a car seat, in particular to a direct-drive manual half-basin lifting device for a car seat. Background technique [0002] The existing manual half-basin lifting structure of car seats is mainly the gear tooth plate type. The half-basin lifting is not a stable four-bar linkage mechanism, so the meshing of the gear and the tooth plate will be difficult after a long-term use of the seat with this structure. Looseness occurs, which affects the adjustment function and even produces abnormal noise. Therefore, the existing technology has the problem and deficiency that it is difficult to ensure the stability of long-term use. Contents of the invention [0003] Aiming at the above-mentioned problems and deficiencies in the prior art, the present invention provides a direct-drive manual semi-basin lifting device for car seats, whic...
