CN203345007U - Steering wheel with heating function - Google Patents

Abstract

The utility model discloses a steering wheel with a heating function. The steering wheel with the heating function comprises a steering wheel body, a plurality of heating silicon wafers are disposed in the steering wheel body, the heating silicon wafers are in a series connection through guide lines to be connected with a power port on the steering wheel body, and the power port is connected with a vehicle power supply. The steering wheel with the heating function has the advantages that the steering wheel can be automatically heated when a driver drives in winter, driving comforts can be improved, electromagnetic interference can also be avoided, and driving comforts and safety can be improved.

Description

A kind of bearing circle with heating function

Technical field

The utility model relates to steering wheel for vehicle, relates in particular to a kind of bearing circle with heating function.

Background technology

Bearing circle is the direction of traffic actuation means, and the parts that must contact while being the chaufeur driving, therefore must guarantee its comfort.Current vehicle steering seldom has heating function, if it is very cool not wear gloves operation meeting cold winter, affects traveling comfort, and wearing gloves can affect processing safety.In order to address the above problem, existing people considers to increase electro-heat equipment at bearing circle, as patent No. ZL201220228794.3 and the disclosed technology contents of ZL201220129842.3, the bearing circle inside that this class has heating function all arranges resistor wire, with wire connecting valve and power supply, its advantage is simple in structure, cost is low, easy to use, improve comfort, but because they are all to adopt the resistor wire heating principle, can be to certain electromagnetic interference of generation such as other instrument Source Musics in car, quality is driven in impact.

The utility model content

Technical problem to be solved in the utility model is to realize that a kind of use is comfortable, and other electronic equipments are affected to little electro heat bearing circle.

To achieve these goals, the technical solution adopted in the utility model is: a kind of bearing circle with heating function, comprise the bearing circle body, be provided with several heating silicon chips in described bearing circle body, between described heating silicon chip, by being connected with the power interface on the bearing circle body after the wire series connection, described power interface is connected with Vehicle Power.

Be in series with switch on described wire, described switch is arranged on the bearing circle body.

Described heating silicon chip arranges 2-10, and is evenly distributed in the steering handwheel of bearing circle body.

The utility model bearing circle can be when driving winter Automatic-heating, can improve driving comfort, can avoid producing again electromagnetic interference, improve traveling comfort and the safety of driving.

The accompanying drawing explanation

Below the content of every width accompanying drawing expression in the utility model specification sheets and the mark in figure are briefly described:

Fig. 1 is for having heating function steering wheel arrangement schematic diagram;

Fig. 2 is for having heating function bearing circle schematic circuit diagram;

Mark in above-mentioned figure is: 1, wire; 2, power interface; 3, heating silicon chip; 4, switch.

The specific embodiment

Referring to Fig. 1, 2 is known, the utlity model has the bearing circle of heating function mainly by being arranged on the intrinsic wire 1 of bearing circle, switch 4, heating silicon chip 3 and power interface 2 form, 3 operated by rotary motion 2-10 steering handwheel inner chambers that are evenly distributed on the bearing circle body of heating silicon chip, as arranged 4 in Fig. 1, lay respectively at the steering handwheel inner chamber up and down on four direction, between all heating silicon chips 3, by wire 1 series connection is rear, with the power interface 2 on the bearing circle body, be connected, source interface 2 is connected with Vehicle Power, and be in series with switch 4 on wire 1, this master cock 4 can be arranged on the bearing circle body, the convenient like this bearing circle heating function that starts when needed.

After the vehicle launch energising, open switch 4, wire 1 conducting, all heating silicon chip 3 heatings, the material of bearing circle body can be plastic material, after 3 heatings of heating silicon chip, by the heat transmission, makes the temperature that whole bearing circle is comfortable in human body.The steering wheel arrangement that the utlity model has heating function is simple, is easy to realize that industrialization takes a large amount of stock productions, with the demand of supply automotive field, can better realize practical value and the economic value of the utility model bearing circle heating function.

Claims (3)

1. the bearing circle with heating function, comprise the bearing circle body, it is characterized in that: be provided with several heating silicon chips (3) in described bearing circle body, between described heating silicon chip (3), by being connected with the power interface (2) on the bearing circle body after wire (1) series connection, described power interface (2) is connected with Vehicle Power.

2. the bearing circle with heating function according to claim 1, it is characterized in that: be in series with switch (4) on described wire (1), described switch (4) is arranged on the bearing circle body.
