Abstract

The invention discloses a seat heightening system based on a 3Z gear mechanism. The seat heightening system comprises a seat, a sliding sail, a front connecting rod and a rear connecting rod, wherein a seat cushion part of the seat is supported on the sliding rail through the front connecting rod and the rear connecting rod, and a four-bar mechanism is composed of the front connecting rod, the rear connecting rod, the seat cushion part and the sliding rail. The seat heightening system further comprises the 3Z gear mechanism for driving the front connecting rod and the rear connecting rod to swing up and down. When the seat heightening system based on the 3Z gear mechanism is compared with an existing seat heightening system, the 3Z gear mechanism is adopted for directly driving a seat and connecting rod mechanism, the structure is more compact, universality is higher, the weight is small, and the size is small. In addition, the strength of 3Z gears is larger than 500 Nm, and safety is greatly enhanced.

Description

technical field [0001] The invention relates to the technical field of seat height adjustment systems, in particular to a seat height adjustment system based on a 3Z gear mechanism. Background technique [0002] The height adjustment devices used in passenger car seats are generally divided into two types, electric and manual, according to different configuration requirements of users. Electric seat height adjustment devices currently on the market mainly use a motor assembly to drive the gear plate and drive a four-bar linkage mechanism to realize the height adjustment function. At present, similar mechanisms in the market are facing problems such as heavy weight, complex structure, limited output torque, and high cost. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a seat height adjustment system based on a 3Z gear structure which is light in weight, simple in structure, large in output torque and lower in pr...
