Abstract

The utility model discloses a steering wheel and a seat heater, which are made of organic semiconductor materials. The utility model has the characteristics of automatic control temperature, sustained temperature, softness, flexibility, etc. The hands, the waist and the buttocks of drivers warm and comfortable by utility model, channels are dredged, and finger numbness is eliminated. The utility model is convenient for enhancing work efficiency, and is the ideal product for heating the low temperature parts, such as hands, waists, and buttocks of drivers.

Description

Steering wheel and seat heater for vehicle

The utility model is a kind of human body hand, waist, the blood circulation of stern position to be improved, and satisfies people to low temperature heating, the new demand of physiotherapy articles for use and the design-calculated temperature booster from hand, waist, stern.

Automobile, operator on the tractor are when steering vehicle, always there is a hand to handle and holds direction at any time, so constantly can not the departure direction dish, arrived winter weather cold, at present, the warming measure of most automobile and trac. is not ideal, the driver is kept out the cold to such an extent that have on leather gloves and operate, make troubles to machine department steering vehicle like this, even, can increase very big potential danger owing to have on the muffler operation.

The purpose of this utility model is to release a kind of electro-heat equipment that is installed on bearing circle and the seat, can make driver's hand, waist, stern warm comfortable, and passages through which vital energy circulates mediation, the numb art of elimination finger are of value to and increase work efficiency.

Concrete measure of the present utility model is as follows: motor vehicle steering wheel, seat heater, form by organic PTC exothermic body, dedicated fixed card, lead, switch.What electric heating element adopted is flaky semiconductor material organic PTC, soft flexible, but automatic constant-temperature when being heated to body heating's optimum temperature, compare with traditional alloy silk electric heating element, at safety, reliability, aspect such as energy-conservation, heat retaining property and mechanical strength all improves a lot and breaks through, and there are many outstanding dots on the organic PTC surface, both anti-skidding, but stimulating acupoint dredges the channels again.

Below in conjunction with accompanying drawing the utility model is elaborated:

Fig. 1 is the utility model electric heating element figure;

Fig. 2 is that the utility model electric heating element is at the steering wheel position scheme drawing.

Fig. 3 is the utility model electrothermal principle figure;

Fig. 4 is that the utility model electric heating element is at the seat position view.

That the organic PTC exothermic body has is temp autocontrolled, stable performance, characteristics such as soft flexible, can be warmed up to the design-calculated Curie-point temperature in 3-5 minute to its energising back, and can continue constant temperature, therefore, it is reached the purpose of heating as the main element of bearing circle, seat heater.As Fig. 2, in the place that driver's two hands are often held bearing circle, will long 130mm, wide 120mm, 1 two of thick 1mm organic PTC exothermic bodys are fixing with dedicated fixed card 2, press Fig. 3 electrothermal principle with two block semiconductor exothermic material organic PTC parallel connections, according to Fig. 2 lead 3 trends, switch 4 is installed in place by driver's choosing, and any one lead is connect the general supply insurance by switch 4 controls, and another lead is at correct position and car body bonding.The enforcement of seat and bearing circle are in like manner.

This heater structure is simple, and manufacturing and use are all very convenient, and the characteristics of long service life are arranged, and is the desirable good merchantable brand of numerous drivers' hand, waist, the heating of stern position low temperature, physiotherapy.

Claims

1, bearing circle, seat heater comprise organic PTC exothermic body 1, dedicated fixed card 2, lead 3, switch 4, it is characterized in that:

What electric heating element adopted is the flaky semiconductor material, and the organic PTC softness is flexible.

2, bearing circle as claimed in claim 1, seat heater is characterized in that: there are many outstanding little round spots on flaky semiconductor exothermic material organic PTC surface.
