Description

Technical Field

[0001] The utility model relates to the technical field of seat cushions, and in particular to a slow-rebound seat cushion. Background Art

[0002] Seat cushions have the effect of keeping warm and being comfortable. They are usually matched with back cushions and are indispensable fabric products in rooms and carriages. They are comfortable to use and have irreplaceable decorative effects that other items cannot replace. A large number of seat cushions are used in transportation vehicles such as buses.

[0003] A Chinese patent discloses a car seat cushion that is easy to disassemble, with the publication number CN219706757U. The technical solution disclosed in the patent document is as follows: a second connecting belt and a first connecting belt are respectively arranged at the front and rear sides of the cushion body, a connecting female buckle and a connecting sub-buckle are respectively arranged on the inner side of the first connecting belt and the outer side of the second connecting belt, and an anti-slip pad is installed at the lower end of the cushion body.

[0004] In order to solve the problem that the installation and disassembly of existing automobile seat cushions are relatively troublesome, the existing technology adopts a method of designing a connecting mother buckle and a connecting sub-buckle and other components to cooperate with each other. However, there is still a situation where ventilation cannot be performed. When users ride in a vehicle for a long time, the air circulation effect of the part in contact with the seat cushion is poor, which is not conducive to the removal of sweat, and thus makes the human body feel uncomfortable. Utility Model Content

[0005] The utility model aims to provide a slow-rebound seat cushion to solve the problem of poor air flow effect on the contact surface of the seat cushion in the prior art.

[0006] The utility model provides the following technical solution: a slow-rebound seat cushion, comprising a positioning base plate, a ventilation buffer mechanism is arranged on the top of the positioning base plate, and a slow-rebound support mechanism is arranged on the top of the ventilation buffer mechanism.

[0007] The ventilation buffer mechanism includes a rubber cover, a branch pipe and a receiving mesh plate. The left side of the branch pipe is fixedly connected with a central pipe, and the back side of the central pipe is movably connected with a filter pipe. A non-woven filter cylinder is fixedly installed on the inner wall of the filter pipe, and an external air pipe is movably connected with the back side of the filter pipe. Sealing rings are fixedly sleeved on the outer walls of the filter pipe and the external air pipe, and the outer walls of the two groups of sealing rings are movably connected with the inner walls of the central pipe and the filter pipe respectively. One end of the external air pipe away from the filter pipe is fixedly connected to the air outlet end of an external vehicle air conditioner. Through the cooperation of the external air pipe, the central pipe and the branch pipe, the air output by the external vehicle air conditioner can be introduced into the interior of this structure and then output from the top to achieve the ventilation function.

[0008] As a preferred embodiment of the above technical solution, the rubber cover is fixedly connected to the top of the positioning base plate, the branch pipe is fixedly connected to the left side of the rubber cover, the top of the rubber cover is fixedly connected to the bottom of the receiving mesh plate, and the rubber cover is used to provide dust-proof protection for the supporting spring.

[0009] As a preferred embodiment of the above technical solution, a support spring is fixedly installed on the top of the rubber cover, and the top of the support spring is fixedly connected to the bottom of the receiving mesh plate. The support spring can increase the softness of the structure.

[0010] As a preferred embodiment of the above technical solution, the slow rebound support mechanism includes a slow rebound sponge board, which is fixedly connected to the top of the receiving mesh plate. The thickness of the slow rebound sponge board is set to three centimeters. By setting the thickness of the slow rebound sponge board to three centimeters, the user comfort can be fully increased.

[0011] As a preferred embodiment of the above technical solution, the top of the slow rebound sponge board is fixedly connected with a fabric protrusion, the inner wall of the fabric protrusion is fixedly connected with a slow rebound sponge protrusion, and the bottom of the slow rebound sponge protrusion is fixedly connected to the top of the slow rebound sponge board. Through the design of the fabric protrusion and the slow rebound sponge protrusion, the anti-slip effect of the top of the structure is improved.

[0012] As a preferred embodiment of the above technical solution, a breathable sponge strip is fixedly connected to the inner wall of the slow-rebound sponge board, and a breathable through hole is opened on the top of the breathable sponge strip. The breathable performance of the structure can be further increased through the design of the breathable sponge strip and the breathable through hole.

[0013] As a preferred embodiment of the above technical solution, the front side of the fabric protrusion is fixedly connected with a Velcro, and the front side of the fabric protrusion is detachably connected with a silicone leg support strip through the Velcro. The silicone leg support strip can provide soft support for the user's legs and reduce the user's fatigue.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The utility model can transmit the air output by the external vehicle air conditioner to the inner cavity of the central pipe through the design of the external air pipe, and the air is then evenly transported to the inside of the structure from the branch pipe, and then output from the top of the structure, thereby increasing the air circulation effect of the part in contact with the user and increasing the comfort of the user. At the same time, the ventilation gas can be filtered through the design of the non-woven filter cylinder to avoid the problem that impurities in the air can easily cause clogging effect inside the structure.
