Abstract

The invention discloses an electric height adjusting device for a seat. The electric height adjusting device comprises a seat height adjusting toothed plate and an electric mechanism driving the seat height adjusting toothed plate to rotate. The electric mechanism comprises a reduction gearbox body, a motor, a worm, a bevel gear component, a flexible bearing, a flexible wheel, a rigid wheel body, a reduction gearbox cover and an output transmission piece. The direct-current motor is used as a power source of the electric mechanism, motor torque is transmitted to the worm and then transmitted to the bevel gear component through the worm, and first-level speed reduction of the electric mechanism is composed of the worm and the bevel gear component. After first-level speed reduction transmission is completed, power is output to the output transmission piece through a harmonic gear mechanism composed of the bevel gear component, the flexible bearing, the flexible wheel to be output. The electric height adjusting device for the seat has the advantages of being small in size, large in output torque, large in transmission ratio, high in transmission precision, small in return stroke clearance, high in bearing capacity and the like, adjustment handleability and the overall strength of the seat are increased, and the noise level is greatly lowered.

Description

technical field [0001] The invention relates to the technical field of seats, in particular to an electric seat height adjustment device, which can adjust the height of a seat, especially a car seat, to rise and fall. 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 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. Almost all driving devices on the market are more or less faced with problems such as large volume, low transmission accuracy, large system backlash, low transmission ratio, low load-carrying capacity, and high requirements on the driving motor. [0003] The specific main problems of the height adjustment device of this structure include: [0004] 1. Large size and poor installation:...
