Detailed Description

The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

Referring to fig. 1, the embodiment discloses a cushion with adjustable hardness, a foaming body 1 is arranged inside the cushion, a groove is formed in the foaming body 1, an inflatable reticular air bag 2 is connected in the groove, and the reticular air bag 2 and an air pump 4 are connected through an air duct 3.

Wherein the air pump 4 is used for inflating the reticular bag 2 to make it expand and extracting air from the reticular bag 2 to reduce the expansion degree of the reticular bag 2.

The opening of recess can produce bigger sunken volume in order to obtain soft impression when making foaming body 1 pressurized, and the hardness of cushion can effectively be adjusted in the cooperation of rethread recess and the 2 inflation degrees of netted air bag.

Above-mentioned netted air pocket 2 adopts network structure, can make the interior gas of bag flow to different directions and position for the gas flow distribution's process is more mitigateed and even, and the riding that causes when having avoided adopting a whole gasbag is uncomfortable that the gas charging is too fast, the air current is unstable and local inflation obviously etc. causes.

In one embodiment, the groove is a net-shaped groove, and the shape of the net-shaped groove is matched with that of the net-shaped air bag 2, so that the net-shaped air bag 2 is matched with the net-shaped groove, and the net-shaped air bag 2 is convenient to fix. Wherein, netted recess (having a plurality of depressed parts) structure can be separated foaming body 1 for a plurality of independent foaming unit to can also make foaming body 1's whole sunken obtaining the decentralization (every foaming unit all shares and bears corresponding pressure) when increasing foaming body 1's sunken volume, easily cause the problem of local collapse when having avoided only setting up a depressed part, for example, if wholly hollowing out on foaming body 1 and only forming a depressed part, then when netted air pocket 2 inflation degree is lower or inflation degree is zero, will produce when this cushion pressurized and collapse and cause and take the discomfort.

In one embodiment, the reticular groove comprises a plurality of transverse grooves and longitudinal grooves which are arranged in a staggered manner to form a plurality of concave parts, the reticular air bag 2 comprises a plurality of transverse inflatable strips and longitudinal inflatable strips which are arranged in a staggered manner and are communicated with each other, each transverse groove contains a corresponding transverse inflatable strip, and each longitudinal groove contains a corresponding longitudinal inflatable strip;

two adjacent horizontal grooves are equidistant in every netted recess and arrange, and two adjacent vertical grooves are equidistant in every netted recess to through the horizontal groove and the vertical groove of evenly arranging and will foam body 1 and separate for a plurality of foaming units of evenly arranging, improve the atress homogeneity of foaming unit, make the holistic sunken more homogenization of foaming.

In one embodiment, the transverse grooves and the corresponding transverse inflatable strips can be fixed in a bonding mode, the longitudinal grooves and the corresponding longitudinal inflatable strips are also fixed in a bonding mode, the connection mode is convenient to operate, and the positioning effect is good.

In one embodiment, the mesh-shaped groove may be opened in the middle of the bottom surface of the foaming body.

In one embodiment, the air duct 3 is provided with an air valve 5 for controlling the air pump 4 to inflate or deflate the mesh-like air bag 2 and for adjusting the air pressure to control the degree of inflation of the mesh-like air bag 2.

In one embodiment, the foam body 1 is a polyurethane foam board, has a good supporting effect and certain elasticity, and can bear a large impact load.

In one embodiment, the air duct 3 is connected with a silencer to reduce the gas noise generated during inflation and air exhaust, so as to create a quiet environment in the vehicle and enhance the riding comfort.

The use method of the cushion with adjustable hardness of the embodiment comprises the following steps: when the driver and the passenger need to increase the hardness of the cushion, the air pump 4 is controlled to inflate the reticular air bag 2, the reticular air bag 2 is inflated to gradually fill all the sunken parts (the transverse groove and the longitudinal groove) of the reticular groove, the overall hardness of the cushion is gradually increased, the sinking amount of the passenger when the passenger sits on the seat is reduced, and when the required hardness is reached, the driver and the passenger can close the air pump 4 to stop inflating; when the driver or passenger needs to reduce the hardness of the cushion to increase the softness of the cushion, the air pump 4 can be controlled to partially or completely pump out the air in the mesh-shaped air bag 2 to reduce the expansion degree of the mesh-shaped air bag 2, so that the foaming body 1 can generate a larger amount of recess to increase the softness of the cushion.

The embodiment also discloses a seat, which comprises the cushion and a backrest connected with the cushion.

The embodiment also discloses an automobile which comprises the seat.

The automobile seat cushion can be subjected to hardness adjustment, so that a user can perform personalized adjustment according to driving road conditions or the height and the weight of the user, the riding comfort of the user is greatly improved, and the application range is wide; the hardness adjusting process is mild and uniform, the adjusting effect is good, and the user experience effect is greatly improved.

The above-mentioned embodiments are merely preferred embodiments for fully illustrating the present invention, and the scope of the present invention is not limited thereto. Equivalent substitutes or changes made by the technical personnel in the technical field on the basis of the utility model are all within the protection scope of the utility model. The protection scope of the present invention is subject to the claims.
