Description

A kind of anti-rain and anti-fog car rearview mirror

technical field

The utility model belongs to the technical field of traffic safety and auto parts, in particular to a mixed ventilation and heating anti-rain and anti-fog automobile rearview mirror.

Background technique

When driving in rainy or foggy weather, the rearview mirror of the car is easily wetted by rain and fog, making the rearview mirror blurred, affecting the driver's vision to a certain extent, and laying hidden dangers for the occurrence of traffic accidents. Usually, the probability of traffic accidents in rainy and foggy weather is much higher than that in normal weather, so rearview mirrors with rainproof and antifog functions are very important.

Contents of the invention

In order to effectively solve the problem that the car rearview mirror is wet by rain and fog, the utility model continuously cleans the car rearview mirror lens through the combination of heating the car rearview mirror lens and wind power to remove rain, so as to achieve the driver's vision clearer purpose.

A rainproof and anti-fog automotive rearview mirror, comprising a rearview mirror housing assembly, an electric heating system, a ventilation system and a circuit protection system, wherein the rearview mirror housing assembly includes a rearview mirror housing and a rearview mirror The lens, the electric heating system is a resistance wire heater, the ventilation system includes an air collection port, an air outlet and a filter screen, and the circuit protection system includes a circuit protection shell, a heat insulation layer and a drainage tank.

The rearview mirror lens is embedded in the edge of the rearview mirror housing, and the edge of the rearview mirror housing protrudes from the plane of the rearview mirror lens by 1-2cm. The output of the spiral air outlet around the rearview mirror lens achieves the purpose of defogging the rearview mirror lens and blowing raindrops on the rearview mirror lens; the resistance wire heater is arranged behind the rearview mirror lens to play a role in heating The effect of the rearview mirror lens; the ventilation system includes an air collection port, an air outlet and a filter screen, wherein the air collection port and the filter screen are arranged at the rear of the rearview mirror housing, and the air outlet is arranged around the rearview mirror lens, so that the The air entering the air collecting port at the bottom can be output from the air outlet through the channel inside the casing; the circuit protection system is fixed inside the rearview mirror casing to protect the internal circuit of the rearview mirror casing from short circuit due to moisture; the heat insulation The layer is arranged between the resistance wire heater and the internal circuit of the rearview mirror housing to avoid thermal aging of the internal circuit of the rearview mirror housing.

The air outlets of the utility model are evenly arranged on the inner frame of the rearview mirror housing, and the air outlets are spiral air outlets.

The air collecting port of the utility model is arranged on the back of the rearview mirror housing to avoid the position of the automobile turn signal, and this position can improve the air intake efficiency when the automobile is running.

There is a layer of metal filter screen at the air collecting port of the utility model, and the filter screen is arranged on the inner layer of the rearview mirror housing, which can prevent fallen leaves and other sundries in the environment from entering the rear view mirror through the air collecting port to block the ventilation system.

The utility model is provided with an independently sealed circuit protection housing inside the rearview mirror housing to prevent short circuit of the internal circuit and the resistance wire heater of the rearview mirror housing by the moist air entering through the air collecting port in rainy and foggy days.

The drainage groove described in the utility model is arranged at the lowest point below the rearview mirror, and the opening is a drainage groove of 0.3-0.5cm, which ensures that the rainwater entering from the air collection port in rainy days can be discharged from the rearview mirror housing, and at the same time, a drainage groove is arranged at the bottom It also minimizes loss of ventilation system air flow.

The beneficial effects of the utility model are:

1. The air collecting port is set at the rear of the rearview mirror housing, so that a larger flow of gas enters the rearview mirror housing when the car is driving at high speed, generating stronger airflow and better cleaning effect of the rearview mirror lens;

2. The heat insulation layer is arranged between the resistance wire heater and the internal circuit, so that when the resistance wire heater heats the rearview mirror lens, it can avoid aging or short circuit of the rearview mirror internal circuit.

detailed description

Below in conjunction with Fig. 1, Fig. 2, Fig. 3, Fig. 4 specific embodiment and the utility model are described in further detail: when the automobile is driving in rainy or foggy days, due to the forward movement of the automobile, the air produces a backward movement relative to the automobile. The air flow enters the interior of the rearview mirror housing 2 through the air collecting port 4, and the mesh opening radius of the filter screen 7 provided at the air collecting port 4 is very small, which can isolate debris larger than the mesh opening radius in the rear Outside the mirror housing 2; the circuit protection housing 6 wraps all the circuits and heating systems inside the rearview mirror housing 2. When raindrops enter the air collection port 4 in rainy days, the rainwater can be isolated, and the rainwater flows along the rearview mirror housing. 2 Drainage groove 8 at the bottom to drain. After the airflow enters the rearview mirror housing 2, according to the inertia of the airflow, it is finally discharged according to the spiral trajectory from the opening direction provided by the air outlet 5; The mist on the mirror eyeglass 1 evaporates quickly due to the combined effect of the flow of the air outlet 5 air and the heating of the resistance wire type heater 3, and keeps the rearview mirror eyeglass 1 clean. At the same time, the heat insulating layer 9 isolates the resistance wire heater 3 from the internal circuit, thereby protecting the circuit and preventing the circuit from aging due to heat.

According to the dual function of electric heating and drying and air ventilation system, the utility model realizes the continuous cleaning of the automobile rearview mirror, and protects the circuit inside the rearview mirror housing 2 by the dual function of the circuit protection housing and the filter screen. , so as to ensure the driving safety of the driver.
