Embodiment 1

[0024] Embodiment 1: as figure 1 As shown, a car seat height adjustment device has two sliding rails 11A / 11B fixed side by side on the bottom of the vehicle body, and the codes A and B respectively represent the left component and the right component; the two sliding rails 11A / 11B Each is equipped with an upper slide rail 13A / 13B, and the two-way upper slide rail 13A / 13B is horizontally fixedly connected to a double-axis motor 2 through a motor installation bracket 1. The double-axis motor 2 is a stepping motor with shaft extension at both ends, and the stepping motor has The advantage of accurate and convenient control is that the shaft extensions at both ends can be used in one machine, especially to ensure the synchronization of the left and right transmission chains. The left and right output ends of the biaxial motor 2 are respectively connected to the input ends of the gear box 3A / 3B fixed at both ends of the motor mounting bracket 1, and the vertical output ends of the ...

Embodiment 2

[0030] Embodiment 2: The optimal initial setting angle between the rear rocker 7A / 7B and the upper slide rail 13A / 13B is 25°. At this time, the traction point Q, the front connection point of the height adjustment link 4A / 4B and the rear rocker The rotation point Z of 7A / 7B, the three-point relationship should take the traction point as the apex to form a right-angle relationship, and then the torque generated by the traction force on the rear rocker reaches the maximum value.

Abstract

The invention discloses an automobile seat height adjusting device. A double-shaft motor is transversely fixed between upper sliding rails in lower sliding rails arranged on a vehicle body bottom plate in a sliding fit mode, the left output end and the right output end of the double-shaft motor are connected with gearboxes fixed to the two ends, the gearboxes are in vertical output connection withheight adjusting connecting rods, and the height adjusting connecting rods are connected with rear rockers rotationally connected to the upper sliding rails. The upper end of the rear rocker is connected with a seat cushion rear transverse pipe, the seat cushion rear transverse pipe is connected with the upper end of a front rocker through a side plate, and the lower end of the front rocker is rotationally connected with an upper sliding rail. The rear rocker, the side plate, the front rocker and the upper slide rail form a double-rocker mechanism; and the seat cushion is arranged between theside plates. The double-shaft motor drives the rear rocker to rotate through the gear box and the height adjusting connecting rod, so that the double-rocker mechanism is pushed to drive the seat cushion installed between the side plates, and the purpose of adjusting the height of the seat is achieved. Gearboxes at the two ends of the double-shaft motor are worm reducers, and the worm reducers onthe two sides have the self-locking function of symmetrical locking.

Description

technical field [0001] The invention relates to the technical field of car seat structures, in particular to a height-adjustable device for a car seat. Background technique [0002] With the continuous development of automobile technology and driving concepts, there are more and more requirements for the functionality and structural diversity of car seats. Most of the existing car seat height adjustment mechanisms are complex in structure and unilaterally locked, which cannot meet the requirements of easy operation and high-intensity rate changes. The prior art has various operating implements and transmission structures for seat height adjustment, each with advantages and disadvantages. For example, the utility model of patent No. 201721253854.6 is a driver’s seat height adjustment mechanism, which is operated by a height adjustment pump, which not only takes up a lot of space but also has the potential disadvantage of failing the mechanism due to the high failure rate of ...
