Steering wheel capable of conducting heating according to hand temperature

Abstract

A steering wheel capable of conducting heating according to hand temperature comprises an annular outer layer and an annular inner layer, wherein the inner layer is wrapped in the outer layer, and the inner layer and the outer layer are divided into a plurality of inner-layer accommodating grooves and outer-layer accommodating grooves which have the same shape and same area and are attached correspondingly; an electric heating element is arranged in each inner-layer accommodating groove, and a temperature sensing element is arranged in each outer-layer accommodating groove to be used for acquiring the temperature value and comparing the temperature value with a preset low-temperature threshold value and a preset high-temperature threshold value after sensing hand temperature independently, outputting a heating electric signal to an electric heating element if the temperature value is lower than the low-temperature threshold value so that the electric heating element can be switched on to conduct heating, outputting a cooling electric signal to the electric heating element if the temperature value is higher than the high-temperature threshold value so that the electric heating element can stop heating, and outputting a thermoregulation electric signal to the electric heating element if the temperature value is between the low-temperature threshold value and the high-temperature threshold value (low-temperature threshold value<=temperature value<= high-temperature threshold value) so that the electric heating element can conduct thermoregulation.

Description

technical field [0001] The invention relates to a steering wheel, in particular to a steering wheel which is heated according to the temperature of hand-to-body bonding. Background technique [0002] In the prior art, people will put a steering wheel cover on the steering wheel of the car, which can prevent the steering wheel from getting dirty and keep the hands warm when driving. However, the effect of this warming method is not good. Then a new steering wheel with a heating function was developed on the market, that is, the heating element built into the steering wheel is heated to keep the user's hands warm. Although this heating method has made great progress compared with the traditional steering wheel cover, it still has certain defects. Specifically, when the steering wheel is heated, it heats the entire ring-shaped steering wheel. However, in practical applications, users When holding the steering wheel, the hand body will not cover the entire surface of the steeri...

Problems solved by technology

Although this heating method has made great progress compared with the traditional steering wheel cover, it still has certain defects. Specifically, when the steering wheel is heated, it heats the entire ring-shaped steering wheel. However, in practical applications, users When holding the steering wheel, the hand body will not cover the entire surface of the steering wheel, that is, the surface of the steering wheel has a certain area that does not fit the user's hand body, which will cause waste of power resources and disperse heat, which cannot be concentrated User's hand is heated

[0003] In the actual environment, not all positions of the user's hand body need to be heated, and the body temperature of different positions of the hand body is different. Adjust the temperature according to the difference

In addition, the heated steering wheel in the prior art will continue to heat after heating, and the user needs to manually turn off the switch of the heating device to stop the heating. Reheating, but the existing technology cannot automatically turn off the heating function when the user's hand temperature reaches a certain amount of heat
