Description

Technical Field

[0001] The utility model relates to the technical field of automotive rearview mirrors, and specifically to an automotive rearview mirror with automatic water mist drying function. Background Art

[0002] The automotive rearview mirror with automatic water mist drying function enables the rearview mirror lens to automatically remain clear and not be interfered by water mist in rainy days or humid environments, thereby ensuring the clear line of sight of the driver and improving driving safety.

[0003] In order to remove the water mist on the automotive rearview mirror, the existing method is to install heating elements, such as electric heating wires or thin film heaters, inside the rearview mirror of the vehicle. When the driver turns on the rearview mirror heating function, an electric current will pass through the heating element, causing it to generate heat. This heat will be transferred to the surface of the rearview mirror, thereby increasing the temperature of the mirror surface. As the temperature of the mirror surface rises, the water mist on the mirror surface will evaporate.

[0004] However, the rearview mirror heating function usually needs to be activated when the external temperature is lower than a certain value (such as below 20 degrees Celsius). When the external temperature is relatively high, even if the rearview mirror heating function is turned on, due to the high ambient temperature, the heat generated by the electric heating wire or thin film heater is not sufficient to quickly raise the temperature of the lens surface and evaporate the moisture and fog. This method depends on the external environment, so its applicability is not high.

[0005] If the vehicle is in a stationary state, the driver can wipe off the water mist by hand. However, if water mist appears on the rearview mirror during vehicle driving, it will seriously interfere with the driver's line of sight, increase the driving difficulty and potential safety hazards, making the driver unable to clearly observe the traffic conditions behind. If the driver attempts to wipe off the water mist on the rearview mirror by hand during driving, it will distract their attention and increase the risk of traffic accidents. Especially in high-speed driving or complex traffic environments, such distracted operations may bring serious consequences. Summary of the Utility Model

Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1 - 6 , the present invention provides a technical solution:

[0028] Refer to Figures 1 - 6 As shown in , an automatic water mist air-drying automotive rearview mirror includes a rearview mirror housing 1 and a lens 2, including an air inlet 4 opened on one side of the rearview mirror housing 1 and located behind the lens 2, a chamber 5 opened on the rearview mirror housing 1, and an air outlet groove 16 opened at the bottom of the chamber 5 and located above the lens 2. The air outlet groove 16 is vertically corresponding to the outer surface of the lens 2.

[0029] The lens 2 inside the rearview mirror housing 1 faces the rear of the vehicle. Therefore, during the driving of the vehicle, the wind blows against the outer wall of the rearview mirror housing 1, that is, behind the lens 2. The air inlet 4 is located behind the lens 2. Therefore, during the driving of the vehicle, part of the wind will enter the chamber 5 through the air inlet 4. After the wind enters the chamber 5, it hits the inner wall of the chamber 5, and then the wind will float out from the air outlet groove 16 to the surface of the lens 2, dispersing the water mist formed on the outer wall of the lens 2, so that the water mist is quickly washed towards the bottom of the lens 2, and then flows out from the inner bottom wall of the rearview mirror housing 1, realizing the removal of the water mist on the lens 2.

[0030] Refer to Figures 5 - 6 , an arc-shaped block 6 is fixedly installed on the inner wall of the chamber 5, and a plurality of funnels 7 are fixedly installed at the bottom of the arc-shaped block 6. The bottom end of the funnel 7 corresponds to the outer surface of the lens 2.

[0031] The air in chamber 5 first enters the arc-shaped block 6 and then enters the multiple funnels 7. The function of the funnels 7 is to reduce the cross-sectional area of the gas outlet, so as to increase the flow rate of the gas. According to Bernoulli's principle, an increase in flow rate will lead to a decrease in static pressure and an increase in impact force. Then the gas ejected from the funnels 7 will be more impactful, making it easier for the gas to disperse the water mist on the surface of the lens 2, and the impactful gas can blow multiple areas of the lens 2, so as to prevent the gas from dispersing as soon as it floats out of the air outlet groove 16.

[0032] Refer to Figures 1 - 6 , a fixing rod 3 is arranged in the chamber 5. The fixing rod 3 is provided with a through hole 13, and the position of the through hole 13 corresponds to that of the air inlet 4. The fixing rod 3 is provided with a plurality of air outlet holes 15, and the air outlet holes 15 correspond to the outer surface of the lens 2.

[0033] A part of the gas in the chamber 5 enters the fixing rod 3 through the through hole 13 and then floats to the outer wall of the lens 2 through the plurality of air outlet holes 15, ensuring that multiple areas of the lens 2 can be blown by the wind. This is to prevent the gas ejected from the funnel 7 from not being able to blow to the middle and lower parts of the lens 2, because the gas will float into the air after being ejected. Therefore, the fixing rod 3 is moved left and right along one side of the lens 2, so that the gas ejected from the air outlet holes 15 can cover multiple areas of the lens 2, and the fixing rod 3 can be made of a transparent material to prevent the fixing rod 3 from blocking the lens 2.

[0034] Refer to Figures 5 - 6 , the rearview mirror housing 1 is provided with a sliding groove 12, and the fixing rod 3 is slidably connected with the sliding groove 12, and the outer wall of the fixing rod 3 is in contact with the inner wall of the sliding groove 12.

[0035] The sliding groove 12 provides a space for the fixing rod 3 to slide left and right, so that the fixing rod 3 can slide along the sliding groove 12 when it needs to move.

[0036] Refer to Figures 5 - 6 , a cavity 8 is arranged in the fixing rod 3. The through hole 13 is communicated with the cavity 8, and the cavity 8 is communicated with the air outlet holes 15.

[0037] The wind directly enters the cavity 8 through the through hole 13, and the cavity 8 provides a guiding function for the wind, so that the wind can smoothly reach the air outlet holes 15 and then float out.

[0038] Refer to Figures 5 - 6 , a fan blade 9 is arranged in the chamber 5. The inner wall of the chamber 5 is rotatably connected with a bidirectional lead screw 11. A plurality of fan plates 10 are fixedly installed on the outer wall of the bidirectional lead screw 11. The fan plates 10 are meshed with the fan blade 9, and the fixing rod 3 is threadedly connected with the outer wall of the bidirectional lead screw 11.

[0039] After the wind enters the chamber 5, it will impact the fan blade 9, causing the fan blade 9 to rotate. After the fan blade 9 rotates, it will move the fan plate 10, thereby causing the fan plate 10 and the bidirectional lead screw 11 to rotate. After the bidirectional lead screw 11 rotates, the fixed rod 3 will slide along the outer wall of the bidirectional lead screw 11, achieving the effect of automatically moving the fixed rod 3.

[0040] Refer to Figure 5 , a rotating rod 14 is rotatably connected to the inner wall of the chamber 5, and the fan blade 9 is fixedly installed on the outer wall of the rotating rod 14.

[0041] The rotating rod 14 is used to support the fan blade 9, so that the fan blade 9 is fixed inside the chamber 5. Then, when the fan blade 9 is blown, it can rotate along the inner wall of the chamber 5 through the rotating rod 14.

[0042] Refer to Figures 1 - 4 , the outer wall of the lens 2 is fixedly connected to the inner wall of the rearview mirror housing 1, and the fixed rod 3 is located inside the rearview mirror housing 1.

[0043] The rearview mirror housing 1 provides stable support for the lens 2, enabling the lens 2 to be fixed outside the vehicle, making the lens 2 more stable.

[0044] Working principle:

[0045] The lens 2 inside the rearview mirror housing 1 faces the rear of the vehicle. Therefore, during the driving of the vehicle, the wind will blow against the outer wall of the rearview mirror housing 1, that is, behind the lens 2. The air inlet 4 is located behind the lens 2. Therefore, during the driving of the vehicle, part of the wind will enter the chamber 5 through the air inlet 4. After the wind enters the chamber 5, it hits the inner wall of the chamber 5, and then the wind will float out from the air outlet groove 16 to the surface of the lens 2, dispersing the water mist formed on the outer wall of the lens 2, causing the water mist to be quickly washed towards the bottom of the lens 2, and then flowing out from the inner bottom wall of the rearview mirror housing 1, achieving the removal of the water mist on the lens 2.

[0046] The wind in the chamber 5 first enters the arc-shaped block 6, and then enters the multiple funnels 7. The function of the funnels 7 is to reduce the cross-sectional area of the gas outlet, increasing the flow rate of the gas. According to Bernoulli's principle, an increase in flow rate will lead to a decrease in static pressure and an increase in impact force. Then, the gas ejected from the funnels 7 will be more impactful, making it easier for the gas to disperse the water mist on the surface of the lens 2, and the impactful gas can blow multiple areas of the lens 2, preventing the gas from dispersing as soon as it floats out from the air outlet groove 16.
