Description

Technical Field

[0001] The utility model relates to the technical field, in particular to a ventilation and heat dissipation structure of a car seat. Background Art

[0002] In recent years, the automobile industry has developed rapidly, and cars have become one of the common tools that people need in their daily lives. As an important component that affects the comfort and safety of passengers, more and more car models have added electrical functions such as ventilation and massage to the rear seats to improve the comfort and luxury of the seats.

[0003] For example, the announcement number is CN219789971U, a ventilation and heat dissipation structure of a car seat, comprising: a backrest, a plurality of air outlets are arranged on the front of the backrest, a fixing interface for connecting with a child safety seat is arranged on the back of the backrest, and the fixing interface includes a connecting shaft; a cover is detachably connected to the backrest, the cover is arranged on the fixing interface, the cover is provided with an air inlet, and the connecting shaft is exposed outside the cover; a heat dissipation component is arranged in the backrest, the heat dissipation component includes a fan, and the fan rotates to drive air to enter from the air inlet and be discharged from the air outlet;

[0004] The ventilation and heat dissipation structure of the automobile seat in the above-mentioned application is achieved by directly setting the air inlet on the cover used to cover the fixed interface, that is, combining the ventilation grille and the rear top tether cover into one part, thereby reducing the number of parts and components and lowering the manufacturing cost; at the same time, the number of openings is reduced to improve the appearance quality of the seat. However, the backrest of the current automobile seat is easy to fit completely with the back of the human body, and the heat at the fitting point cannot be dissipated, resulting in insufficient heat dissipation effect on the back of the human body and poor effect in use. Therefore, the market urgently needs to develop a ventilation and heat dissipation structure for automobile seats to help people solve the existing problems. Utility Model Content

[0005] The purpose of the utility model is to provide a ventilation and heat dissipation structure for a car seat, so as to solve the problem in the above-mentioned background technology that the backrest of the car seat is easy to fit completely with the back of the human body, and the heat at the fitting point cannot be dissipated, resulting in insufficient heat dissipation effect on the back of the human body and poor use effect.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a ventilation and heat dissipation structure of a car seat, comprising a main shell, an elastic band is arranged on one side of the main shell, a rubber top is arranged on the elastic band, a plurality of the rubber tops are arranged, a lifting mechanism is arranged in the main shell, two of the lifting mechanisms are arranged, a roller is arranged between the two lifting mechanisms, when the roller moves vertically, the elastic band is squeezed and extended, when the elastic band is extended, a plurality of the rubber tops are staggered and ejected.

[0007] Through the above technical solution, an elastic band and rubber end heads are utilized. There are multiple rubber end heads, and the material used is hard rubber. When the roller moves up and down, it will squeeze the elastic band, causing the rubber end heads to be pushed out. Since the rubber end heads are independently arranged, each time they are pushed out, they will squeeze the filling wrapped by the human back and the seat backrest. There will be a height difference between multiple extrusion heads, so that there is a gap between the human back and the seat backrest, allowing air to circulate, thereby efficiently dissipating heat from the human back, improving the heat dissipation effect. During the extrusion process, the rubber end heads can also squeeze and massage the human back, playing a role in massaging and relaxing, making the functional aspect of this ventilation and heat dissipation structure more comprehensive and the use effect better.

[0008] In a preferred example of the present utility model, it can be further configured as follows: A lead screw is rotatably connected inside the lifting mechanism. A lead screw seat is threadedly connected to the outside of the lead screw. An axle seat is arranged between the lead screw seat and the roller. A driven gear is installed on the outside of the lead screw. A driving device is arranged inside the main machine shell. The output end of the driving device is connected to a driving gear, and the driving gear is engaged with the driven gear.

[0009] Through the above technical solution, the driving device drives the driving gear to rotate. The driving gear drives the lead screw to rotate through the driven gear. The rotation of the lead screw drives the lead screw seat to move vertically, and the lead screw seat drives the roller to move vertically up and down.

[0010] In a preferred example of the present utility model, it can be further configured as follows: An air inlet chamber is arranged on the main machine shell. A connecting pipe is arranged on one side of the air inlet chamber. An air outlet is arranged below the air inlet chamber.

[0011] Through the above technical solution, the connecting pipe is used to connect the air supply pipeline of the car air conditioner, and the cold air of the air conditioner is blown towards the back of the seat through the air outlet.

[0012] In a preferred example of the present utility model, it can be further configured as follows: A power distribution connector is arranged on the air inlet chamber. A heating resistor electrically connected to the power distribution connector is arranged inside the air inlet chamber. A temperature sensor is arranged inside the air inlet chamber.

[0013] Through the above technical solution, the heating resistor can be used to heat the air inside the air inlet chamber, so that the air output from the air inlet chamber can be independently controlled. When the temperature of the car air conditioner is too low, the heating resistor can be used for secondary heating and then adjusted to a suitable temperature before being blown towards the back of the chair, thereby improving the use comfort of the ventilation and heat dissipation structure.

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

[0015] 1. The utility model utilizes an elastic band and rubber end caps. There are multiple rubber end caps, and the material is hard rubber. When the roller moves up and down, it will squeeze the elastic band, causing the rubber end caps to be pushed out. Since the rubber end caps are independently arranged, each time they are pushed out, they will squeeze the back of the human body and the filling wrapped by the seat backrest. There will be a height difference between multiple extrusion heads, so that there is a gap between the back of the human body and the seat backrest, allowing air to circulate, thereby efficiently dissipating heat from the back of the human body and improving the heat dissipation effect. During the extrusion process, the rubber end caps can also squeeze and massage the back of the human body, playing a role in massaging and relaxing, making the ventilation and heat dissipation structure more functional and having a better use effect.

[0016] 2. The utility model uses a heating resistor to heat the air in the air inlet chamber, so that the air output from the air inlet chamber can be independently controlled. When the temperature of the car air conditioner is too low, the heating resistor can be used for secondary heating, and then adjusted to a suitable temperature and blown towards the back of the chair, thereby improving the use comfort of the ventilation and heat dissipation structure.
