Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vehicle seats, and particularly relates to a vehicle seat with good heat conduction. Background Art
[0002] As a component that plays a decisive role in the comfort of vehicle driving and riding, vehicle manufacturers have improved it from different angles, including surface materials, internal fillers, morphological designs, seat heating, etc. Among them, seat heating cooperates with electric heating wires and temperature sensors to enable drivers and passengers to have a good driving and riding experience even in low-temperature situations.
[0003] However, the existing vehicle seats lack a structure for further heat homogenization, and the seat surface is covered with a thick flexible filler. Generally, the flexible filler has good heat insulation performance, so the heat conduction performance is poor. After the seat heating is turned on, the heat cannot be quickly homogenized, resulting in a situation where the local temperature is high while the temperature of other parts is low. The seat surface temperature is uneven, and there is also a lack of an auxiliary heat dissipation structure. In the hot summer, the part of the seat in contact with the skin cannot be blown by the air conditioner, making it easy for the skin contact position to remain stuffy, and the comfort needs to be further improved.
[0004] Therefore, a vehicle seat with good heat conduction is proposed. Content of the Utility Model
[0005] The purpose of the utility model is to provide a vehicle seat with good heat conduction to solve the problems mentioned in the above background art.
[0006] The utility model specifically adopts the following technical solutions to achieve the above purpose:

[0025] As Figures 1 to 4 shown, a car seat with good heat conduction includes a supporting seat 1, a seat cushion 2, a backrest 3 and a headrest 4. The seat cushion 2 is fixedly installed on the top surface of the supporting seat 1. The backrest 3 is arranged at the rear side of the seat cushion 2. The headrest 4 is arranged on the upper side of the backrest 3. A rotation adjustment assembly 5 for driving the backrest 3 to rotate is arranged on the surface of the supporting seat 1. The seat cushion 2 includes an inner box 8. An electric heating tube 15 is fixedly installed inside the inner box 8. The outer layer of the inner box 8 is fixedly wrapped with a first flexible layer 9. A uniform air hole 12 is opened on the surface of the inner box 8 on the side for supporting the human body. A ventilation hole 13 is opened on the surface of the first flexible layer 9 on the side for supporting the human body and a second flexible layer 10 is fixedly installed. The number of the uniform air holes 12 is several and they are evenly distributed. The uniform air holes 12 and the ventilation holes 13 are in one-to-one correspondence and are communicated. A protective skin 11 is fixedly wrapped outside the first flexible layer 9 and the second flexible layer 10. A spring 14 is placed in the ventilation hole 13. The spring 14 is fixedly installed on the surface of the inner box 8. A communication assembly 6 is connected between the seat cushion 2, the backrest 3 and the headrest 4.
[0026] More specifically, by connecting the supporting seat 1 with the air conditioning system and the fresh air system of the car, cold air generated by air conditioning refrigeration can be blown into the supporting seat 1 in high-temperature weather. In low-temperature weather, the air is heated by the electric heating tube 15. Under the action of the communication assembly 6, the air in the supporting seat 1 is blown into the seat cushion 2, the backrest 3 and the headrest 4, so that the air inside the three inner boxes 8 is quickly made uniform. And the air enters the ventilation holes 13 through the uniform air holes 12 and thus comes into full contact with the first flexible layer 9, making the temperature of the first flexible layer 9 quickly uniform, solving the problem of poor heat conduction caused by the large thickness and good heat preservation performance of the first flexible layer 9. The spring 14 is used to fill the ventilation holes 13 and cooperate with the first flexible layer 9 to ensure the elastic supporting force. The second flexible layer 10 is used to buffer stress and avoid the spring 14 from stabbing the human body, thereby ensuring the comfort of driving and riding. While improving the heat conduction performance of the seat, the comfort of the seat is ensured, and both the cooling and heating effects are achieved.
[0027] The supporting seat 1 includes a base box 101. A fresh air pipe 102 and an air conditioning connection pipe 103 are opened on the bottom wall of the base box 101. Ear plates 104 are fixedly installed on the left and right sides of the top surface of the base box 101. The seat cushion 2 is fixedly installed on the top surface of the base box 101 and is located between the two ear plates 104.
[0028] Specifically, by connecting the fresh air duct 102 to the fresh air system of the vehicle and connecting the air conditioner connecting pipe 103 to the air conditioner system of the vehicle, the air inside the base box 101 can interact with the outside through the fresh air duct 102, and the cold air generated by the air conditioner refrigeration can be introduced through the air conditioner connecting pipe 103. The ear plates 104 surround the seat cushion 2 from both sides, making the seat cushion 2 more stable and reliable.
[0029] The rotation adjustment assembly 5 includes a motor 501. The motor 501 is fixedly installed on the side wall of the base box 101. The output end of the motor 501 is fixedly connected with a driving rotating shaft 502. The driving rotating shaft 502 is rotatably installed between the left and right side walls of the base box 101. A driving gear 503 is fixedly installed on the surface of the driving rotating shaft 502. A driven gear 504 is meshed on the surface of the driving gear 503. An installation shaft 505 is fixedly installed on the surface of the driven gear 504. The installation shaft 505 is rotatably installed on the surface of the ear plate 104. A connecting block 506 is fixedly installed on the surface of the installation shaft 505. The connecting block 506 is fixedly installed on the bottom surface of the inner box 8 inside the backrest 3.
[0030] Specifically, after the motor 501 is started, its output end drives the driving rotating shaft 502 and the driving gear 503 to rotate, so that the driven gear 504 meshed on the surface of the driving gear 503 rotates, and then drives the installation shaft 505 fixedly installed on the surface of the driven gear 504 to rotate, so that the connecting block 506 fixedly installed on the surface of the installation shaft 505 rotates, and finally drives the backrest 3 fixedly installed on the surface of the connecting block 506 to rotate, realizing the electric adjustment of the inclination angle of the backrest 3.
[0031] The communication assembly 6 includes an air duct 601, a fan 602, a first communication pipe 603 and a second communication pipe 604. The air duct 601 is fixedly installed on the bottom surface of the inner box 8 inside the seat cushion 2 and is fixedly inserted into the top wall of the base box 101. The fan 602 is fixedly installed inside the air duct 601. The first communication pipe 603 is fixedly installed between the inner box 8 inside the backrest 3 and the inner box 8 inside the seat cushion 2. The first communication pipe 603 is arranged between the two connecting blocks 506. The second communication pipe 604 is fixedly installed between the inner box 8 inside the backrest 3 and the inner box 8 inside the headrest 4.
[0032] Specifically, through the connection of the first communication pipe 603 and the second communication pipe 604, the interiors of the three inner boxes 8 are interconnected. The fan 602 is used to introduce the air inside the support seat 1 into the inner box 8 to promote air flow, so that the heat inside the three inner boxes 8 is quickly and evenly distributed, and then the temperatures on the surfaces of the seat cushion 2, the backrest 3 and the headrest 4 are quickly and evenly distributed.
[0033] The first communication pipe 603 is a telescopic hose, and the second communication pipe 604 is a rigid pipe.
[0034] Specifically, when the backrest 3 rotates, the first connecting pipe 603 will bend and stretch. The second connecting pipe 604 is used to support and fix the headrest 4, and at the same time, the interiors of the backrest 3 and the headrest 4 are connected.
[0035] A protective layer 7 is fixedly connected between the outer surface of the backrest 3 and the outer surface of the seat cushion 2. The protective layer 7 covers the outside of the first connecting pipe 603 and the rotation adjustment assembly 5. The protective layer 7 is made of a flexible elastic material.
[0036] Specifically, the protective layer 7 is used for dust prevention and protection. While improving the aesthetic degree, it prevents passengers from accidentally touching the rotation adjustment assembly 5 and the connection assembly 6, making it safer.
[0037] In summary: By connecting the support seat 1 to the air conditioning system and the fresh air system of the vehicle, cold air generated by air conditioning refrigeration can be blown into the support seat 1 in hot weather, and the air can be heated by the electric heating pipe 15 in cold weather. Under the action of the connection assembly 6, the air in the support seat 1 is blown into the seat cushion 2, the backrest 3, and the headrest 4, so that the air in the three inner boxes 8 is quickly made uniform. And the air enters the ventilation holes 13 through the air distribution holes 12 and thus comes into full contact with the first flexible layer 9, making the temperature of the first flexible layer 9 quickly uniform, solving the problem of poor heat conduction caused by the large thickness and good heat preservation performance of the first flexible layer 9. The ventilation holes 13 are filled with springs 14, which cooperate with the first flexible layer 9 to ensure the elastic support force. The second flexible layer 10 buffers the stress to prevent the springs 14 from stabbing the human body, thereby ensuring the comfort of driving and riding. While improving the heat conduction performance of the seat, the comfort of the seat is ensured, and both the cooling and heating effects are achieved.
