Car headrest structure

Abstract

The invention provides a car headrest structure applied to the field of car seat parts. The car headrest structure comprises a headrest body (1), and a body cavity (2) is formed in the middle of the headrest body (1). The headrest body (1) is further provided with a front air vent (3). A PTC heater (4) is arranged in the body cavity (2), the PTC heater (4) is connected with a control component (5) capable of controlling starting and stopping of heating of the PTC heater (4), and the PTC heater (4) is further connected with a power supply. The car headrest structure is simple in structure and low in manufacturing cost, control over the temperature of the position, close to the neck of a driver or a passenger, of the car headrest portion can be effectively achieved, the effect that the temperature of the neck part and the temperature of other parts of the body of the driver or the passenger are balanced and proper is ensured, obvious temperature difference is avoided, local discomfort of the body of the driver or the passenger is avoided, and finally the driving comfort can be effectively improved for the driver or the riding comfort can be effectively improved for the passenger

Description

technical field [0001] The invention belongs to the field of car seat parts, and more specifically relates to a car headrest structure. Background technique [0002] At present, the automotive air conditioning system is not effective in controlling the temperature of specific parts of the human body and some specific vehicles. If you want to maintain the comfort of the ambient temperature in the car, you must keep the occupant's body temperature balanced and suitable, and there should be no obvious temperature difference. It is difficult to ensure the temperature of the back neck of the occupant, and it is easy to cause a temperature difference between the front face and the back neck of the occupant, causing discomfort in the occupant's neck. However, under extreme weather conditions, such as extremely cold and low temperature conditions, the temperature of the engine rises slowly after ignition, the temperature of the coolant rises slowly, and the vehicle maintains a "col...

Problems solved by technology

[0002] At present, the automotive air conditioning system is not effective in controlling the temperature of specific parts of the human body and some specific vehicles.

If you want to maintain the comfort of the ambient temperature in the car, you must keep the occupant's body temperature balanced and suitable, and there should be no obvious temperature difference. It is difficult to ensure the temperature of the back neck of the occupant, which may easily cause a temperature difference between the front face and the back neck of the occupant, causing discomfort in the occupant's neck

However, under extreme weather conditions, such as extremely cold and low temperature conditions, the temperature of the engine rises slowly after ignition, the temperature of the coolant rises slowly, and the vehicle maintains a "cold cycle". Heating the interior temperature of the car will also cause the engine water temperature to rise more slowly

In an extremely hot environment, the cold air from the air outlet of the air conditioner cannot blow to the back of the neck of the occupants due to the problem of the flow field, which will make the temperature of the occupant's face lower and the temperature of the back of the neck higher

Therefore, the air-conditioning system in the prior art is likely to cause a large temperature difference between different parts of the body of the driver and passengers, which affects the driving comfort.
