Problems solved by technology

[0003] At present, during the use of automobile rearview mirrors, in rainy and foggy weather, a large number of water droplets will condense on the lenses, which greatly reduces the reflective effect of the rearview mirrors and greatly affects the driver's observation of the rear road conditions. In order to solve this problem Generally, electric heating devices are used to remove water, but the disadvantages of this device are also obvious, such as large power consumption, slow heating of the mirror surface, resulting in low water removal efficiency, especially for continuous rainwater, its effect is not ideal

Embodiment 1

[0024] refer to Figure 1-2 , a self-draining automobile rearview mirror housing based on injection mold processing, including a housing 1, a scraper 2 is slidably connected to the housing 1, and soft bristles are fixedly connected to the side wall of the scraper 2. And the scraper 2 is elastically connected to the inner wall of the housing 1 through the conductive spring 3, the side wall of the housing 1 is provided with a ventilation hole 4, and the side wall of the housing 1 is provided with a bar-shaped groove 7, and the bar-shaped groove 7 is embedded with a There is a power generation piece 10, and the power generation piece 10 is electrically connected to the conductive spring 3 through the capacitor 11. Specifically, the power generation piece 10 is made of piezoelectric ceramic material, which can guide the charge to the two plates of the capacitor 11 under constant vibration Above, when the accumulated charge reaches a certain value, the capacitor 11 can conduct the ...

Embodiment 2

[0028] refer to Figure 3-4 , the difference from Embodiment 1 is that the side wall of the scraper 2 is provided with a through hole 13, and the housing 1 is equipped with an air guide tube 15 communicating with the ventilation hole 4, and the air guide tube 15 communicates with the through hole 13 through a bellows 16 , A plurality of capillary holes 14 are opened on the inner wall of the through hole 13 .

[0029] It should be noted that by arranging a plurality of capillary holes 14, since the pore diameter of the capillary holes 14 is extremely small, not only can the air flow in the through holes 13, it will not be discharged from the capillary holes 14, but only along the larger pore diameter. The through hole 13 is discharged, and at the same time, the water drops on the mirror surface can be continuously sucked into the through hole 13 under capillary action, so as to improve the water removal efficiency of the device. A plurality of capillary holes 14 are equally sp...

Abstract

The invention discloses a self-dewatering automobile rearview mirror shell based on injection mold processing; the shell comprises a shell body, a scraping plate is slidably connected into the shell body, the scraping plate is elastically connected to the inner wall of the shell body through a conductive spring, a vent hole is formed in the side wall of the shell body, and a strip-shaped groove is formed in the side wall of the shell body. A power generation piece is embedded in the strip-shaped groove, the power generation piece is electrically connected with the conductive spring through a capacitor, a knocking plate is slidably connected into the strip-shaped groove, a driving device for driving the knocking plate to move up and down is installed in the vent hole, and a drainage groove is formed in the lower end of the shell. The knocking plate continuously moves up and down and forces the power generation piece to vibrate to generate power, so that the capacitor is continuously charged; when charges gathered on the capacitor reach a certain value, the conductive spring can be electrified once, and the scraper blade can be pushed to move back and forth once, so that water drops on the lens are scraped off, and the shell is energy-saving, environment-friendly, high in water removal speed and obvious in effect.

Description

technical field [0001] The invention relates to the related technical field of auto parts, in particular to a self-water-removing automobile rearview mirror housing based on injection mold processing. Background technique [0002] The car rearview mirror is located on both sides of the head of the car, allowing the driver to see through the rear of the car. It is generally composed of a shell and a lens. The shell is basically made of plastic and processed by an injection mold. [0003] At present, during the use of automobile rearview mirrors, in rainy and foggy weather, a large number of water droplets will condense on the lenses, which greatly reduces the reflective effect of the rearview mirrors and greatly affects the driver's observation of the rear road conditions. In order to solve this problem Generally, an electric heating device is used to remove water, but the disadvantages of this device are also obvious, such as large power consumption, slow heating of the mirr...
