Abstract

The utility model relates to a heating device for the reference mirror of a car. The utility model is composed of a main body (2), an adhesive tape (21) of double faces and thermal insulation, a copper foil (22), a heat-emanating sheet (23), a reinforced adhesive tape (24) and an insulating adhesive tape (26) of double faces, etc. The utility model is characterized in that the heat-emanating sheet with high molecular PTC is adopted, the heat-emanating sheet with high molecular PTC is made into sectional type, and each sectional part is thin and has large area; the electrode (231) of the heat-emanating sheet with high molecular PTC is directly led onto an output terminal; thus, the power of the cold state is very small, the heat-emanating speed is fast and homogeneous, and the frost and the mist can be quickly eliminated. The price of the utility model is lower than the price of the product of the same type.

Description

A kind of automobile rearview mirror heating arrangement

The utility model relates to the Automobile accessory, particularly a kind of automobile rearview mirror heating arrangement.

As everyone knows, the automobile that belongs to the vehicle is many, it plays an important role in communications and transportation, yet various automobiles travel on highway, safety traffic is important again, especially in autumn and winter season, weather that particularly colds and heat succeed each other and greasy weather, the back mirror of automobile is very easily gone up frost, last fog, have a strong impact on the field of view of automobilist to the rear, be the hidden danger of traffic accident, for preventing the generation of this class accident, the back mirror heating arrangement promptly addresses the above problem, this heating arrangement is embedded in mirror body inside, two vitreums are evenly heated, can in the extremely short time, remove frost and fog on the minute surface, kept minute surface limpid in sight under any weather condition, guaranteed the safety of running car, be common a kind of automobile rearview mirror heating arrangement as shown in Figure 1, it is to adopt two ceramic PTC heating sheets (12) to make pyrotoxin, make two electrodes conduct with double-deck Copper Foil (13), reach thermolysis, its structure is the recess in mirror holder body (1), the two-sided heat insulation adhesive tape (11) that is sticked is established a Copper Foil (13) thereon and is drawn conductive electrode (131), pastes one deck double-sided insulation adhesive tape (15) on Copper Foil (13), one deck Copper Foil (13) again is sticked on upper strata double-sided insulation adhesive tape (15), be provided with two ceramic heating plates of PCT (12) in the middle of the two-layer Copper Foil (13), draw conductive electrode (131) at the upper strata Copper Foil again, and one deck Acrylic Foam Tape (16) that is sticked on the upper strata of upper strata Copper Foil (13), the mirror (14) that is sticked on it is drawn two conductive electrode (131) to introduce electric current at two Copper Foils (13).This device is because exothermic body PTC ceramic plate is too small, so power ratio is bigger, and is general single at 36W, because exothermic body is two-sided conduction, therefore double-deck Copper Foil will take into full account insulativity, so manufacture craft is more loaded down with trivial details again.

The purpose of this utility model is exactly the shortcoming that exists at above-mentioned back mirror heating arrangement, provides that a kind of technology is simple, cost is low, the automobile rearview mirror heating arrangement of power saving.

Technical conceive of the present utility model:

According to the purpose of this utility model, a kind of automobile rearview mirror heating arrangement is provided, its structure pastes the two-sided heat insulation adhesive tape of a polyacrylic acid for the recess on the mirror holder body, on two-sided heat insulation adhesive tape, stick the heating sheet of the ultra-thin software of high molecular PTC and make thermal source, the heating sheet makes sectional type, its two ends scribble the PTC exothermic material, middle just high molecule plastic, be provided with copper mesh in the both sides of heating sheet and make electrode and directly electrode being guided on the lead-out terminal, adding the thin insulation double faced adhesive tape of one deck again above the heating sheet takes up bonding and insulating effect, and at the thin bonding one deck Copper Foil in double-sided insulation adhesive tape upper strata, play thermolysis, the powerful Acrylic Foam Tape of bonding again one deck on the Copper Foil upper strata again is in order to bonding mirror.

Accompanying drawings structure of the present utility model and embodiment:

Fig. 1 is the cross-sectional schematic of common a kind of automobile rearview mirror heating arrangement.

Fig. 2 is a cross-sectional schematic of the present utility model.

Fig. 3 is a heating plate scheme drawing of the present utility model.

Fig. 4 is the schematic top plan view of embodiment of the present utility model.

(1) is the mirror holder body, (11) be two-sided heat insulation adhesive tape, (12) be the PTC ceramic heating plate, (13) be Copper Foil, (131) be conductive electrode, (14) be mirror, (15) be the double-sided insulation adhesive tape, (16) be Acrylic Foam Tape, (2) be the mirror holder body, (21) be two-sided heat insulation adhesive tape, (22) be Copper Foil, (23) be high molecular PTC heating sheet, (24) be powerful Acrylic Foam Tape, (25) be mirror, (26) be the double-sided insulation adhesive tape, (251) be electrode, (232) be left heating plate, (233) be right heating plate, (234) be connector.

As shown in Figure 2, structure of the present utility model is by body (2), two-sided heat insulation adhesive tape (21), Copper Foil (22), heating sheet (23), mightiness belt (24), double-sided insulation adhesive tapes (26) etc. constitute, wherein the recess at mirror holder body (2) pastes the two-sided heat insulation adhesive tape of one deck polyacrylic acid (21), the ultra-thin software heating sheet of the high molecular PTC that is sticked on two-sided heat insulation adhesive tape (21) (23) is made thermal source, heating sheet (23) makes sectional type, as shown in Figure 3, on left heating plate (232) and right heating plate (233), scribble the PTC exothermic material, intermediate connector (234) is not coated with exothermic material PTC, has only high molecule plastic, and on heating sheet (23), following both sides pile things on has copper mesh directly to guide to electrode (231) on the lead-out terminal, above heating sheet (23), paste the thin double-sided insulation adhesive tape (26) of one deck again, play bonding and insulating effect, again at thin double-sided insulation adhesive tape (26) upper strata bonding one deck 0.1mm Copper Foil (22), it is to play thermolysis, and on the Copper Foil upper strata the powerful Acrylic Foam Tape (24) of bonding again one deck, when using, stick mirror (25) again.

In conjunction with the accompanying drawings 2 and accompanying drawing 4 explanation embodiment of the present utility model:

With assembled car back mirror heating arrangement; it is low to tear protection; minute surface (25) is bonding on it; install again on the motor head; connect electrode connecting line; the heat that the high molecular PTC heating plate distributes evenly is dispersed on the minute surface by Copper Foil, at once frost on the minute surface and fog is removed totally, guarantees traffic safety.
