Description

Technical Field

[0001] The invention relates to a blind spot-filling rearview mirror, in particular to a defogging self-cleaning blind spot-filling rearview mirror. Background Art

[0002] In order to provide the driver with sufficient vision, the exterior rearview mirrors of buses generally have a main rearview mirror and a blind spot rearview mirror. However, in bad weather such as rain, snow, cold weather, etc., the main rearview mirror and the blind spot rearview mirror are prone to fogging, being covered by rain and snow, and being attached with dust and other impurities, making it difficult for the driver to see the road conditions in time, posing a safety hazard. Summary of the invention

[0003] The purpose of the present invention is to provide a defogging self-cleaning blindness-complementing rearview mirror capable of timely removing impurities such as water drops and dust on the mirror surface of the rearview mirror.

[0004] The technical solution for achieving the purpose of the present invention is as follows:

[0005] The defogging self-cleaning blind spot-filling rearview mirror comprises a mounting seat and a rearview mirror housing, wherein a fan and a mounting tube are fixed in the mounting seat, one end of the mounting tube is fixedly connected to the inner wall of the mounting seat, and the other end extends from the mounting seat and extends into the rearview mirror housing, and one end of the mounting tube extending into the rearview mirror housing is fixedly connected to the rearview mirror housing;

[0006] The mounting tube is a hollow tube structure, a ventilation tube is arranged inside the mounting tube, the ventilation tube contacts the inner wall of the mounting tube, one end of the ventilation tube extends into the mounting seat and faces the position where the fan discharges air, and the other end extends into the rearview mirror housing;

[0007] The rearview mirror housing comprises a main rearview mirror housing and a blind-complementary rearview mirror housing, wherein the main rearview mirror is installed in the main rearview mirror housing, and the blind-complementary rearview mirror is installed in the blind-complementary rearview mirror housing;

[0008] One end of the ventilation pipe extending into the rearview mirror housing is provided with a first branch pipe and a second branch pipe, the first branch pipe extends into the main rearview mirror housing, and the second branch pipe extends into the blind rearview mirror housing;

[0009] The main rearview mirror housing includes a first side edge located on both sides of the main rearview mirror, a first upper side edge located above the first side edge, and a first lower side edge located below the first side edge near the main rearview mirror, a first gap is formed between the first upper side edge and the main rearview mirror, and an end of the first branch pipe extending into the main rearview mirror housing has a first air outlet, the first air outlet faces the first gap, and the air blown out from the first air outlet passes through the first gap and is blown onto the mirror surface of the main rearview mirror;

[0010] The blind-complementing rearview mirror housing includes second side edges located on both sides of the blind-complementing rearview mirror, a second upper side edge located above the second side edge, and a second lower side edge located below the second side edge near the blind-complementing rearview mirror, a second gap is formed between the second upper side edge and the blind-complementing rearview mirror, and one end of the second branch pipe extending into the blind-complementing rearview mirror housing has a second air outlet, the second air outlet faces the second gap, and the air blown out from the second air outlet passes through the second gap and is blown onto the mirror surface of the blind-complementing rearview mirror;

[0011] The cross-sectional area of ​​the ventilation pipe is greater than the sum of the cross-sectional area of ​​the first branch pipe and the cross-sectional area of ​​the second branch pipe;

[0012] The first air outlet and the second air outlet are elliptical in shape, the major axis of the first air outlet is greater than twice the diameter of the first branch pipe, and the minor axis is less than half the diameter of the first branch pipe, the major axis of the second air outlet is greater than twice the diameter of the second branch pipe, and the minor axis is less than half the diameter of the second branch pipe.

[0013] After adopting the above structure, when there are impurities such as water drops and dust on the main rearview mirror and / or the supplementary blind rearview mirror, the driver can control the fan to start by pressing the button inside the car, and the wind blown by the fan is blown into the main rearview mirror housing and the supplementary blind rearview mirror housing through the ventilation pipe, and is blown out from the first gap and the second gap, so that the water drops and dust and other impurities on the mirror surface of the main rearview mirror and the supplementary blind rearview mirror can be quickly and timely removed, thereby improving the safety of vehicle driving. By setting the size of the cross-sectional area of ​​the ventilation pipe and the sum of the cross-sectional areas of the first branch pipe and the second branch pipe, the flow rate of the wind will increase when it enters the first branch pipe and the second branch pipe from the ventilation pipe, thereby improving the effect of the blown wind in removing impurities such as water drops and dust. By setting the elliptical first air outlet and the second air outlet, the second air outlet can be The first air outlet and the second air outlet are more adapted to the first gap and the second gap, thereby reducing the loss of air volume and wind speed of the wind blown onto the mirror surface. At the same time, the fan is arranged in the mounting seat instead of the rearview mirror housing, which reduces the weight of the rearview mirror housing and the vibration amplitude of the rearview mirror during vehicle driving. It also avoids the situation where the fan and the rearview mirror housing are separated due to the vibration of the rearview mirror during vehicle driving, thereby improving the service life of the product. The double-layer pipe structure of the mounting pipe and the ventilation pipe also strengthens the connection strength between the rearview mirror housing and the mounting seat, improves the structural strength of the mounting pipe, and reduces the risk of the mounting pipe being bent and damaged by force. The present invention can effectively remove impurities such as water droplets and dust on the mirror surface of the rearview mirror, is safe and reliable, and has a long service life.
