Fig. 1 is a schematic structural view of a seat 100 with adjustable hardness according to an embodiment of the present application, and fig. 2 is a schematic structural view of an adjusting device 4.

Referring to fig. 1 and 2, the seat 100 with adjustable hardness includes: seat cushion 1 and backrest 2. The seat cushion 1 and/or the backrest 2 are/is filled with a compressible first elastic member 3, and the original volume of the first elastic member 3 can be adjusted to change the hardness of the first elastic member 3, and the original volume refers to the volume of the first elastic member 3 when the seat is empty.

In the present embodiment, the seat cushion 1 and the backrest 2 constitute a basic structure of the seat, and can satisfy basic functions of riding a driver. Since the seat cushion 1 and/or the backrest 2 are/is filled with the compressible first elastic member 3, the driver can feel a soft feel when using the seat. Next, since the original volume of the first elastic member 3 can be adjusted to change the hardness of the first elastic member 3, specifically, when the original volume of the first elastic member 3 is reduced, the deformation range of the first elastic member 3 is reduced, so that the driver feels harder when using the seat, and when the original volume of the first elastic member 3 is increased, the deformation range of the first elastic member 3 is enlarged, so that the driver feels softer when using the seat. Therefore, even after the seat leaves the factory, the hardness of the seat can be adjusted according to the actual demands of drivers and passengers, and the driving experience of the drivers and passengers is improved.

The shape of the seat cushion 1 and the backrest 2 may be a square disk-shaped body, a circular disk-shaped body, or may be other shapes, which is not limited in the embodiment of the present application. The fabric of the seat cushion 1 and the backrest 2 may be cloth fabric, leather fabric, or may be fabric made of other materials, which is not limited in the embodiment of the present application. The seat cushion 1 and the backrest 2 may be connected to or separated from each other, and the embodiment of the present application is not limited thereto.

The hardness is a physical quantity describing the degree of hardness of the object, and the softer the object, the smaller the hardness and the harder the object, the greater the hardness.

Referring to fig. 1 and 2, when the driver is the elderly, the hardness of the seat needs to be reduced, the elderly sits on the seat at the moment, the original volume of the first elastic member 3 is increased, and the deformation range of the first elastic member 3 is enlarged, so that the elderly feel softer. When the driver and the passenger are young people, the hardness of the seat is required to be increased, the young people sit on the seat at the moment, then the original volume of the first elastic piece 3 is reduced, the deformation range of the first elastic piece 3 is reduced, and the young people feel softer.

In some embodiments, referring to fig. 1 and 2, the first elastic member 3 is a block-shaped body, the larger surface of which is parallel to the structural plane of the seat cushion 1 and/or the backrest 2. Since the seat cushion 1 and the backrest 2 are generally block-shaped, the first elastic member 3 is formed into a block-shaped body and is filled in the seat cushion 1 and the backrest 2, so that the appearance of the seat cushion 1 is more attractive, and in addition, a driver and a passenger can sit more comfortably.

The structural plane of the seat cushion 1 is a plane formed by connecting the front and rear ends of the upper surface of the seat cushion 1. The structural plane of the backrest 2 is a plane formed by connecting the upper and lower ends of the larger side of the backrest 2.

The adjusting device 4 may apply pressure to the first elastic member 3, and the applied pressure may be adjusted, when the applied pressure is reduced from large to small, the original volume of the first elastic member 3 is enlarged, so that the first elastic member 3 is softened, and when the applied pressure is reduced from small to large, the original volume of the first elastic member 3 is reduced, so that the first elastic member 3 is hardened. So that the original volume of the first elastic member 3 is more convenient to adjust.

In some embodiments, referring to fig. 1 and 2, the adjusting device 4 comprises a pressing plate 41, the pressing plate 41 being parallel to the larger surface of the first elastic member 3 for compressing the first elastic member 3. Since the pressing plate 41 is used to compress the first elastic member 3, the pressure applied to the first elastic member 3 can be more uniform, and the deformation of the first elastic member 3 can be more uniform, so that the softness and hardness of each position of the seat can be uniform, and the comfort of the seat can be improved.

The pressing plate 41 may be a rigid plate, has small deformation, may be a metal plate, may be a high-strength plastic plate, or may be another rigid plate, and the embodiment of the present application is not limited thereto.

In some embodiments, referring to fig. 1 and 2, the adjustment device 4 further comprises a driving member 42, the driving member 42 being configured to drive the platen 41 to move in a direction perpendicular to the structural plane of the seat cushion 1 and/or the backrest 2. The driving member 42 is driven by a mechanical structure, so that the driving force is saved more than manual driving, the driving efficiency is higher, and the driving experience of drivers is improved.

To achieve the function of automatic adjustment of the seat, in some embodiments, referring to fig. 1 and 2, the driving member 42 is an intelligent driving member electrically connected to the automatic control member a. Wherein, this intelligent driving piece includes singlechip 421, and this singlechip 421 is connected with automatic control spare A electricity.
