A hydraulic seat system

Abstract

A hydraulically controlled seat system, including a hydraulic drive system; the hydraulic drive system includes a hydraulic pump, a switching valve, a filter, a sensor, a first overflow valve, an oil tank, a second overflow valve, an accumulator, a throttling valve; wherein the hydraulic pump extracts the oil in the oil tank, the filter is arranged between the hydraulic pump and the oil tank, the output end of the hydraulic pump is provided with the sensor, and the sensor is A pressure sensor, the output end of the hydraulic pump is connected to the switching valve, when the switching valve is at the first position, the hydraulic pump outputs oil to the first passage, and when the switching valve is at the second position, the hydraulic pump Output oil to the second passage.

Description

technical field [0001] The invention relates to the field of automobile safety, in particular to a hydraulic control seat system. Background technique [0002] With the rapid development of self-driving cars, future self-driving cars will be more of a combination of manual and automatic modes, or manual and automatic vehicles can switch between manual and automatic. The seat can be rotated at any angle according to the driver's needs, so as to satisfy people's comfort in automatic driving. The space layout inside the car must have a big change. People want to turn around to enjoy the scenery outside the window, or turn around to talk and entertain with other friends and relatives in the car. On the other hand, there is still a big gap between the self-driving technology and the "zero accident" that people expect, and there are many cases of traffic accidents of self-driving cars around the world. When self-driving cars face unavoidable collisions, it is a good choice to re...

AI Technical Summary

Problems solved by technology

[0004] 1. In the automobiles of the prior art, collision is an unavoidable problem. Even if the driving skills are good, various situations may be encountered on the road, and collisions cannot be avoided. However, the automobiles of the prior art do not have enough protection for personal safety

[0005] 2. If the driving position is equipped with a protective shell, the right-hand side of the driving position often needs more space, such as the control unit and storage box on the right-hand side, but the protective shell will hinder the activity space on the right-hand side

[0006] 3. According to the statistics of the Automobile Safety Association, one of the reasons for car accidents is that when the driver needs to pick up and place items in the back seat, when the driver leans back, due to the automatic response of the joints, the feet will subconsciously stretch forward, which is easy Trigger the accelerator, even in the parking state at this time, it is easy to empty the accelerator

cause an accident or reduce the life of the car

[0007] 4. If the car seat in the prior art is rotated, it is only a conventional motor to control the rotation, and the buffered rotation cannot be realized, and the buffered rotation can play a good role in buffering when it is hit

[0008] 5. The piston drive structure of the prior art needs to reserve the position of the liquid opening to ensure the smooth flow of liquid and the reciprocating movement of the piston. However, there is no corresponding structural design for the ring piston

[0009] 6. If the car seat takes into account the protective effect of the protective shell and the problem that the protective shell affects the activity space, the two are contradictory, and how to coordinate this problem is difficult

[0010] 7. When the car seat in the prior art uses a buffered rotating structure, there will inevitably be a rotation limit, which makes it impossible to realize a large-scale rotation of the seat

Unable to achieve e.g.: the front seat turns backwards to interact with the rear seat

[0011] 8. The mounting belt of the prior art is fixed on the B-pillar, but due to the space limitation of the B-pillar, the upper point of the seat belt cannot be adjusted, and the dynamic adjustment of the seat belt according to the height cannot be realized
