Description

Technical Field

[0001] The utility model relates to the technical field of automobile seats, in particular to a variable hardness seat and an automobile. Background Art

[0002] At present, most vehicle seats on the market have a fixed and single hardness, and the seat hardness is generally adjusted by covering the seat with different thicknesses of the soft foam layer. Even if the seat comfort is adjusted during the seat development process, only whole seats with different foam hardness are produced. In the actual driving process, due to differences in the body shape of passengers, driving habits, etc., different evaluation results often appear for the same product. In order to meet the comfort needs of more passengers, seats with freely adjustable hardness have become the design choice of seat manufacturers.

[0003] The current design scheme is to compress or relax the foam layer in a specific direction through a mechanical device, and realize the seat hardness adjustment function by pre-compressing the foam layer; 202310446207.0 provides a design scheme for adjusting the seat hardness by compressing the foam layer through a motor and an elliptical adjustment rod, and realizes intelligent operation through a display unit and a controller; however, this scheme requires the installation of multiple adjustment motors and transmission mechanisms, which makes it difficult to control the design cost and occupied space, and the weight of the entire chair also greatly exceeds the current mainstream design. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a variable hardness seat and a car, which can freely adjust the seat hardness according to the needs of passengers, and when the vehicle collides and impacts, the seat will give the occupants a reverse supporting force, thereby ensuring that the anti-diving function is not invalid; at the same time, the seat will absorb part of the impact energy to reduce the damage to the occupants.

[0005] The utility model provides a variable hardness seat, comprising a seat frame, a plurality of rows of thickness adjustment fluid bags, a fluid delivery pipe and an electric fluid storage tank;

[0006] Several rows of thickness adjustment fluid bags are fixedly arranged on the upper surface of the seat frame from front to back. The thickness adjustment fluid bags can adjust the thickness of the stored fluid according to the needs of the passengers to meet the needs of different passengers for seat surface comfort.

[0007] One end of the fluid delivery tube is connected to each thickness regulating fluid bag respectively, and the other end of the fluid delivery tube is connected to the electric fluid storage tank. Each row of thickness regulating fluid bags has a separate fluid delivery tube, and the thickness of the thickness regulating fluid bag can be adjusted separately to meet the needs of different human bodies.

[0008] The upper surfaces of several rows of thickness-adjusting fluid bags are covered with a soft foam layer of seat fabric to form a complete seat surface.

[0009] Several rows of thickness regulating fluid bags are adjacent to each other, and the lower end surface of each row of thickness regulating fluid bags is bonded to the upper surface of the seat frame at the corresponding position to prevent each row of thickness regulating fluid bags from sliding backward due to gravity after the fluid is injected.

[0010] A through hole is provided in the middle of the seat frame corresponding to the position between two adjacent thickness adjustment fluid bags from front to back, and the fluid delivery pipe is matched and correspondingly penetrated in the through hole and the fluid delivery pipe is connected to the rear side wall of each row of thickness adjustment fluid bags to facilitate each row of thickness adjustment fluid bags to be quickly and evenly filled with fluid material from the middle to both sides.

[0011] Each row of thickness regulating fluid bags is divided into 2-4 independent chambers from left to right, and the rear side wall of each chamber is connected to the front end of a fluid delivery tube to more accurately control the filling of the fluid in the corresponding area into the corresponding chamber.

[0012] The electric fluid storage tank includes a fluid storage chamber, several electric pumps, and a controller; the liquid inlets of the several electric pumps are connected to the fluid storage chamber through pipelines, and the liquid outlets of the several electric pumps are respectively connected to the corresponding fluid delivery pipes, and the controller is electrically connected to each electric pump to adjust the inflow and outflow of fluid in each row of thickness-regulating fluid bags according to the needs of passengers.

[0013] The electric fluid storage tank also includes a refrigerator and a heater, which are respectively arranged in the fluid storage cavity, and the refrigerator and the heater are respectively electrically connected to the controller so as to continuously cool or heat the fluid according to the needs of the passengers, and transport it to each row of thickness adjustment fluid bags to achieve the cooling or heating effect of the seats.

[0014] The fluid storage chamber contains non-Newtonian fluid, which is a rubber solution or ceramic slurry. Considering the safety of the car when it collides, this structure is filled with non-Newtonian fluid. The occupant quickly presses down on the seat cushion surface, which is equivalent to the liquid surface of the non-Newtonian fluid being suddenly impacted by an external force. The particles in the fluid do not have sufficient time to move, and will give the occupant a reverse supporting force like a solid, thereby ensuring that the anti-diving function does not fail. In a collision, the non-Newtonian liquid can absorb the impact energy brought by the occupant and reduce the damage to the occupant. After the collision, the external force disappears and the non-Newtonian fluid returns to the properties of an ordinary liquid.

[0015] The material of each row of thickness adjustment fluid bags is TPO (full name: Thermoplastic polyolefin, thermoplastic polyolefin elastomer is a high-performance polyolefin product, which is rubber elastic at room temperature, has the characteristics of low density, large bending, high low-temperature impact resistance, easy processing, and reusability), single-layer thickness 0.45mm-0.55mm, compression strength 200N-240N, and burst strength 0.4MPa-0.8MPa.

[0016] A car comprises a cockpit and a central controller, and also comprises the variable hardness seat. The variable hardness seat is arranged in the cockpit, and a controller is electrically connected to the central controller.

[0017] Beneficial Effects

[0018] The utility model can freely adjust the hardness of the seat according to the needs of passengers, and when the vehicle collides and impacts, the seat will give the occupants a reverse supporting force, thereby ensuring that the anti-diving function is not invalid; at the same time, the seat will absorb part of the impact energy to reduce the damage to the occupants.
