Abstract

The utility model discloses a vapour-proof rear-view mirror of automobile, comprising a shell body, a mirror surface, a support and a rotation shaft. The reverse surface of the mirror surface is evenly provided with three n'-shaped electrothermal wires, and the both ends of the three n'-shaped electrothermal wires are fixedly connected through a plurality of clips which are straightened and intercepted and are made of the same materials with the electrothermal wires. The internal and external electrothermal wires are connected in parallel and are connected in parallel with the middle electrothermal wire. Each electrothermal wire penetrates the shell body through an electric wire and is connected with the power supply, and a switch is arranged in each wire line. When the rear-view mirror generates the vapour, frosts or has rain water in bad weather, the switch of the electrothermal wires is opened. The electrothermal wires generate heat, and the heat penetrates the mirror surface to transfer outwards and makes the vapour, frost and rain water evaporated, and the original normal situation is recovered. So the driver can easily observe the condition out of the automobile, and the running safety is ensured.

Description

The antifog back mirror of automobile

Technical field:

The utility model relates to the auto parts and components field, the antifog back mirror of particularly a kind of automobile.

Background technology:

Automobile rearview mirror is requisite parts in the vehicle safety travel, when automobile during in travels down, the situation that chaufeur is observed the left and right vehicle wheel rear by left and right sides back mirror, to guarantee vehicle cut-ins or lane change or safety when stopping.But present automobile rearview mirror runs into adverse weather can be produced fog or frosting or rainwater is arranged, and makes chaufeur can not observe the situation at left and right vehicle wheel rear, is unfavorable for the safe driving vehicle.

Summary of the invention:

In order to overcome the prior art deficiency, the utility model provides a kind of automobile antifog back mirror, and this back mirror can be removed fog or the frosting or the water smoke of automobile rearview mirror, and then guarantees the safety traffic of chaufeur.

For addressing the above problem, the technical solution adopted in the utility model is: the antifog back mirror of a kind of automobile, comprise housing, minute surface, support, rotating shaft, it is characterized in that: at the heating wire of uniform three roads of the reverse side of minute surface " ∩ " shape, above-mentioned three road heating wire are fixing with glueing joint with the clamp two ends of several and the stretching intercepting of the same material of heating wire, inside and outside twice heating wire parallel connection is in parallel with middle heating wire again, passes housing by electric wire separately and is connected with power supply, and in circuit separately switch is set.

The beneficial effects of the utility model are: when running into generation fog or the frosting of adverse weather back mirror or water smoke is arranged, open the switch of inside and outside twice heating wire, heating wire produces heat and outwards transmits fog or frosting or the rainwater evaporation that makes on the minute surface through minute surface, recover original normal condition, make the driver can observe the outer situation of car smoothly, guarantee traffic safety; If the situation of minute surface mist, frost, rain is serious, the switch of heating wire in the middle of can opening simultaneously.

Description of drawings:

Below in conjunction with the drawings and the specific embodiments the utility model is further described.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is schematic circuit diagram of the present utility model.

Among the figure 1, housing; 2, support; 3, rotating shaft; 4, joint; 5, electric wire; 6, switch; 7, switch; 8, outer course heating wire 9, middle heating wire; 10, interior road heating wire; 11, minute surface; 12, clamp.

The specific embodiment

In Fig. 1, minute surface (11) is embedded on the plastic casing (1), housing (1) passes the location with support (2) with rotating shaft (3), the reverse side of minute surface (11) is uniform with the heating wire of three roads " ∩ " shape, they are respectively outer course heating wire (8), middle heating wire (9), interior road heating wire (10), with glueing joint fixing with AB glue with 10-15 clamp (12) two ends of the stretching intercepting of the same material of heating wire, inside and outside twice heating wire (10), (8) one end parallel connections, in parallel with middle heating wire (9) again, connect electric wire (5) by joint (4) separately, electric wire (5) passes the hole that is positioned at the following close rotating shaft (3) of housing (1) and connects switch (6) respectively, switch (7) is connected with automobile power source is anodal again; The common joint (4) that inserts of the other end of three road heating wire is connected with power cathode by electric wire.In Fig. 2, inside and outside twice heating wire (10), (8) parallel connection are provided with switch (6) in the circuit, and be in parallel with middle heating wire (9) again, and switch (7) is set in the circuit, is connected with automobile 12V power supply again.

When running into generation fog or the frosting of adverse weather back mirror or water smoke being arranged, the driver at first opens the switch (6) of inside and outside twice heating wire, if situation is serious, and the switch (7) of heating wire in the middle of then opening again, three road heating wire are worked simultaneously, eliminate fast to look the barrier phenomenon on the back mirror.

Claims

1. antifog back mirror of automobile, comprise housing, minute surface, support, rotating shaft, it is characterized in that: at the heating wire of uniform three roads of the reverse side of minute surface " ∩ " shape, above-mentioned three road heating wire are fixing with glueing joint with the clamp two ends of several and the stretching intercepting of the same material of heating wire, inside and outside twice heating wire parallel connection is in parallel with middle heating wire again, pass housing by electric wire separately and be connected, and in circuit separately, switch is set with power supply.
