Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1-3, the present invention provides an automobile seat cushion, which comprises a seat covering layer 1, an intermediate covering layer 2 and a cushion core 3, wherein the intermediate covering layer 2 and the seat covering layer 1 are sequentially covered on the cushion core 3 from inside to outside; the cushion core 3 is formed by meshing a first cushion core 31 and a second cushion core 32; the first cushion core 31 and the second cushion core 32 are both hollow structures with hexagonal prism-shaped vertical periodic arrangement.

Specifically, the cushion core 3 is a hexagonal-prism-shaped hollow structure which is made of a polyurethane foam material and is arranged in a vertical periodic manner, and the hexagonal-prism-shaped hollow structure which is arranged in the vertical periodic manner can reduce the weight of the cushion and improve the bearing strength of the cushion; because a plurality of holes are arranged between the two layers, the manufacturing cost of the automobile cushion can be greatly reduced, and the strength and resilience of the cushion are improved; when sound waves enter the hollow structure, the vibration of air and materials can be caused, and partial sound energy can be converted into heat energy to be dissipated due to friction resistance and viscous resistance, so that the aim of silencing can be achieved under the combined action of other sound-absorbing materials in the automotive trim.

Specifically, the polyurethane foam material is a flexible polyurethane foam material obtained by reacting a polyol composition with polyisocyanate in the presence of a catalyst, a foaming agent, a foam stabilizer and a flame retardant. During manufacturing, the adhesive in the middle of the hexagonal prism-shaped hollow structure which is made of the polyurethane foam material and is vertically and periodically arranged can be achieved by changing the raw materials, additives and the manufacturing process. The melting point of the adhesive can be guaranteed to be lower than the softening point of the hollow structure by utilizing the principle, so that the hollow structure, which is arranged in the hexagonal prism-shaped vertical period, of the cushion core 3 can be adhered by adopting the same material, the uniformity of the cushion material is guaranteed, and the manual adhesion traces are weakened.

Preferably, the first cushion core 31 and the second cushion core 32 have the same projection in the vertical surface direction; the surface of the first cushion core 31, which is far away from the side of the central sleeve layer, is provided with a first sawtooth structure, the surface of the second cushion core 32, which is far away from the side of the central sleeve layer, is provided with a second sawtooth structure, and the first sawtooth structure and the second sawtooth structure are mutually matched, meshed and bonded by gluing; the middle sleeve layer 2 covers and shapes the cushion core 3, and the middle sleeve layer 2 is made of soft fabric.

Specifically, all be equipped with the sawtooth on the first cushion core 31 of cushion core 3 and the second cushion core 32 and connect the line, this sawtooth is connected the line and is waved the cutting along original hollow structure, does not influence holistic connection structure.

Preferably, a waist rest is further glued on the other surface of the second cushion core 32 away from the second saw teeth, and the waist rest is made of one or more of rubber, silica gel and latex.

Specifically, the side of the second cushion core 32 facing away from the second serrations is cut into a curve that conforms to the back of the user; the waist rest is additionally arranged near the waist of the user, so that the lumbar of the passenger can be protected, and more comfortable riding experience can be provided for the passenger.

Preferably, the cushion core 3 is coated and shaped by the middle sleeve layer 2; the middle sleeve layer 2 is made of soft fabric, and the soft fabric is cotton-flax fabric blended with silver ion fibers. The middle sleeve layer 2 is wrapped by the seat sleeve; the seat cover is made of leather and is provided with a plurality of ventilation holes; the ventilation through holes can be matched with the hollow structure, so that the whole automobile cushion is of a ventilation structure.

Specifically, the middle sleeve layer 2 of the cushion core 3 is wrapped by soft fabrics, and antibacterial silver ion fibers are blended. The narrow space in the automobile is blocked and difficult to ventilate, and the temperature in the automobile is usually not very low because most automobiles adopt a braking principle that combustion engine oil drives a cylinder to work. Under such conditions, the automobile seat cushion is extremely likely to become a culture dish for bacteria. The silver ions on the surface of the silver ion fiber have very strong biological activity, and can be combined with deteriorated protein to solidify the protein inside and outside the bacterial cell membrane, so that the breathing and the reproduction process of bacterial cells are blocked, and the effects of disinfection and odor removal are achieved. A plurality of small ventilation holes are further formed in the seat cover on the outer surface and matched with the hollow structure, so that the whole automobile cushion can dissipate heat and ventilate.

The beneficial effects of the utility model include: compared with the traditional sponge material, the automobile cushion made of the polyurethane foam material is softer, so that the riding experience of passengers is improved; an antibacterial and breathable middle sleeve layer is additionally arranged between the seat cover and the cushion core; in addition, the cushion core is a hollow structure which is vertically and periodically arranged in a hexagonal prism shape, and the structure improves the supporting force of the traditional cushion and improves the softness of the cushion; due to the special porous structure, the noise of other sound-absorbing plates in the automobile can be well removed, and the riding experience of passengers is further improved; moreover, the hollow structures which are vertically and periodically arranged in the hexagonal prism shape can reduce the manufacturing cost of the cushion, buffer external force to a certain extent, and improve the safety of riding.

The above description of the present invention does not limit the scope of the present invention. Any other corresponding changes and modifications made according to the technical idea of the present invention should be included in the scope of the claims of the present invention.
