Embodiment 1

[0030] This embodiment relates to a vehicle seat pressure adjustment system. In terms of overall structure, it mainly includes a cushion body, a liquid storage unit and a pressure adjustment unit arranged on the vehicle seat, and the backrest and seat cushion on the vehicle seat are at least One of them is provided with a pad body, and the liquid storage unit communicates with the pad body, and a fluid that can communicate between the pad body and the liquid storage unit is stored in the pad body and the liquid storage unit, and the pressure adjustment unit responds to the seat pressure carried by the pad body , and can form the compression or decompression of the liquid storage unit, so that the fluid flows between the liquid storage unit and the cushion body.

[0031] In the vehicle seat pressure adjustment system of this embodiment, by setting the cushion body filled with fluid on the backrest and / or the seat cushion, when the occupant sits on the cushion body, the character...

Embodiment 2

[0041] This embodiment relates to a vehicle seat pressure adjustment system, such as image 3 As shown in , its overall structure is similar to that of the vehicle seat pressure adjustment system described in Embodiment 1, the difference is that the driving part of this embodiment is a linear power output device, and the extrusion part includes a The first squeeze plate unit that can be opened and closed, the fluid storage bag 9 is clamped inside, and the linear power output device is configured to drive the first squeeze plate unit through the elastic member to squeeze the fluid storage bag 9 .

[0042] Specifically, the linear power output device of this embodiment specifically adopts the linear motor 17 , of course, in addition to the linear motor 17 , an air cylinder can also be used. Such as image 3 As shown in , the first extruded plate unit of this embodiment includes a first extruded plate 14 fixed on the vehicle seat, and a second extruded plate 15 hinged at one en...

Embodiment 3

[0046] This embodiment relates to a vehicle seat pressure adjustment system, such as image 3 As shown in , it mainly includes a pad body 3, a liquid storage unit and a pressure regulating unit, wherein the structures of the pad body 3 and the liquid storage unit are similar to those of the pad body 3 and the liquid storage bag 9 described in Embodiment 1, I won't repeat them here.

[0047] In order to reduce the processing cost, the pressure adjustment unit of this embodiment is realized by mechanical elements, and the specific structure of the pressure adjustment unit is as follows image 3 As shown in , it includes a lever member 21 arranged on the vehicle seat, a second extruded plate unit that can be opened and closed, and a first brake line 20 connected between one end of the lever member 21 and the second extruded plate unit , and the second brake line 22 connected between the other end of the lever member 21 and the pad body 3 .

[0048] Wherein, the structure of the...

Abstract

The invention relates to a vehicle seat pressure adjusting system. The vehicle seat pressure adjusting system comprises cushion bodies arranged on a vehicle seat, a liquid storage unit and a pressureadjusting unit, one or more parts of a backrest and a cushion on the vehicle seat are provided with the cushion bodies, the liquid storage unit communicates with the cushion bodies, a fluid which canflow between the cushion bodies and the liquid storage unit is stored in the cushion bodies and the liquid storage unit, in respond to the riding pressure borne by the cushion bodies, the pressure adjusting unit can form the pressing on the liquid storage unit or release the pressure to make the fluid flow between the liquid storage unit and the cushion bodies. According to the vehicle seat pressure adjusting system, the cushion bodies filled with the fluid are arranged on the backrest and/or the cushion, when passengers sit on the cushion bodies, the liquid storage unit can be pressed by thepressure adjusting unit to make the fluid in the liquid storage unit flow into the cushion bodies, thus the high-pressure area of the cushion bodies can be dispersed, meanwhile the uniformity of the pressure distribution on the cushion bodies can also be improved, and the riding comfort of the passengers can be improved.

Description

technical field [0001] The invention relates to the technical field of vehicle seats, in particular to a vehicle seat pressure adjustment system. Background technique [0002] At present, the structure of a car seat mainly includes a seat frame, a foam on the seat frame, and a cover covering the foam. Among them, the main components that determine the comfort of the occupant are the foam and the seat frame supporting the foam. , and after the seat is manufactured, the shape and hardness of the foam and the structure of the seat frame are determined thereupon, so that the seat cannot provide better comfort for occupants of different body types. With the gradual improvement of people's requirements for car comfort and the development of intelligent cockpits, it is urgent to develop a seat that can provide higher comfort for occupants of different sizes. Contents of the invention [0003] In view of this, the present invention aims to propose a vehicle seat pressure adjustme...
