Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to an active anti-fog and rainproof rearview mirror for vehicles. Background Technology

[0002] Rearview mirrors are crucial components for ensuring driving safety, providing drivers with a view of the sides and rear of the vehicle, which is essential for maneuvering such as lane changing, overtaking, turning, and parking. However, in adverse weather conditions such as rain, snow, and fog, the performance of rearview mirrors deteriorates significantly, creating substantial safety hazards.

[0003] Existing technologies have made numerous improvements to vehicle rearview mirrors. For example, Chinese patent CN111845565B discloses a car rearview mirror, including a mounting base, a support mechanism, a protective shell, and a mirror surface. The support mechanism is movably mounted on the top of the mounting base, and the protective shell is movably mounted on the top of the support mechanism. A fixing bracket effectively secures the internal components, preventing them from shifting due to vehicle vibration. Fixing clips allow for quick and easy installation by snapping the device onto the vehicle body, saving installation time. Sealing gaskets prevent water ingress, extending the device's lifespan. Applying force to the mirror surface and adjusting the rotating shaft allows for adjustment of the mirror's angle, making it suitable for different users. Furthermore, the inclusion of a heating layer effectively heats the mirror surface, reducing fogging and improving visibility, thus enhancing the device's practicality and ease of use.

[0004] However, the following problems still exist in actual use:

[0005] 1. The glass defrosting relies solely on heating the electric heating layer, resulting in a slow defrosting speed and an inability to effectively handle different weather conditions;

[0006] 2. Lacking adequate waterproofing and water-repellent properties, it cannot effectively adapt to rainy road conditions.

[0007] Based on this, this utility model designs an active anti-fog and anti-rain rearview mirror for vehicles to solve the above problems. Utility Model Content

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0034] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0035] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-6An active anti-fog and rainproof vehicle rearview mirror includes a rearview mirror body, a rearview mirror connecting assembly, an automatic defogging liquid spraying assembly, a multiplier air pressure cleaning assembly, and a heating defogging and defrosting assembly. The rearview mirror body is connected to the rearview mirror connecting assembly, and the automatic defogging liquid spraying assembly, the multiplier air pressure cleaning assembly, and the heating defogging and defrosting assembly are respectively connected to the rearview mirror body.

[0036] The rearview mirror body includes an air outlet frame 1, a mirror surface 2, a mirror support 4, a central support shell 6, a second air guide shell 7, a first air guide shell 9, and a rearview mirror housing 10. The central support shell 6, the second air guide shell 7, the first air guide shell 9, and the rearview mirror housing 10 are connected by a rearview mirror connecting assembly. The automatic demisting liquid spraying assembly is connected to the central support shell 6. Both the central support shell 6 and the first air guide shell 9 are connected to the multiplier air pressure cleaning assembly. The front end of the central support shell 6 is fixedly connected to the mirror support 4, the front end of the mirror support 4 is fixedly connected to the mirror surface 2, and the air outlet frame 1 is fixedly connected to the front end of the mirror surface 2.

[0037] The rearview mirror connection assembly includes a first bolt 15, a second bolt 18 and a third bolt 21. The rearview mirror housing 10 is fixedly connected to the first air guide housing 9 by the third bolt 21. The first air guide housing 9 is fixedly connected to the second air guide housing 7 by the second bolt 18. The second air guide housing 7 and the central support housing 6 are fixedly connected by the first bolt 15.

[0038] To reduce wind resistance and ensure smooth flow of high-pressure air, the first bolt 15 is streamlined in shape.

[0039] The automatic demisting liquid spraying assembly includes a demisting liquid delivery pipe 11 and a demisting liquid storage tank 5. The demisting liquid storage tank 5 is used to store demisting liquid. One end of the demisting liquid delivery pipe 11 is fixedly connected to the demisting liquid storage tank 5, and the other end of the demisting liquid delivery pipe 11 is fixedly connected to a nozzle. Both the nozzle and the demisting liquid delivery pipe 11 have multiple sets. The number of nozzles and the number of demisting liquid delivery pipes 11 are the same and correspond one-to-one. The demisting liquid delivery pipe 11 delivers the demisting liquid in the demisting liquid storage tank 5 to the nozzle. The nozzle is used to spray the demisting liquid evenly on the mirror surface 2 in the form of atomization to form a layer of demisting liquid surface. The central support shell 6 has a receiving cavity for accommodating the demisting liquid storage tank 5. The rear end of the demisting liquid storage tank 5 is fixedly connected to the central support shell 6.

[0040] A liquid pump, not shown in the figure, is installed inside the demister liquid storage tank 5 to drive the demister liquid from the demister liquid storage tank 5 to the nozzle along the demister liquid delivery pipe 11.

[0041] The defogger fluid is an anti-fogging agent for automotive glass, and its main component is a surfactant.

[0042] The surface-active ingredients in the above-mentioned defogging liquid can effectively reduce the surface tension of water, allowing the rain and fog adhering to the mirror 2 to quickly condense into large droplets and slide off rapidly, thereby achieving the anti-fogging function.

[0043] A sensor for detecting liquid level is fixedly connected to the defrost fluid storage tank 5. The sensor is electrically connected to the vehicle's display screen. The low liquid level indicator is set to A. When the sensor detects that the liquid level in the defrost fluid storage tank 5 is lower than A, the vehicle's external controller receives the signal and reminds the user to add liquid via the display screen.

[0044] The upper end of the demisting liquid storage tank 5 is fixedly connected to the demisting liquid filling pipe 12, and the upper end of the central support shell 6 is provided with a demisting liquid filling port 14. The demisting liquid filling port 14 is connected to the demisting liquid filling pipe 12, and the user can add demisting liquid into the demisting liquid filling pipe 12 through the demisting liquid filling port 14.

[0045] The pressure-boosting cleaning assembly includes a worm gear blower 8. The rear end housing of the worm gear blower 8 is fixedly connected to the first air guide housing 9, the front end housing of the worm gear blower 8 is fixedly connected to the blower pipe 17, the blower pipe 17 is fixedly connected to the second air guide housing 7, an active ventilation port 20 is provided in the middle of the rearview mirror housing 10, and multiple sets of radially distributed passive ventilation ports 22 are provided on the rearview mirror housing 10 around the active ventilation port 20. A natural air guide channel 23 is formed between the rearview mirror housing 10 and the first air guide housing 9, and an internal pressurized air guide channel 24 is formed between the second air guide housing 7 and the central support housing 6. The worm gear blower 8 is connected to an external control system.

[0046] An active ventilation port 20 is provided in the middle of the rearview mirror housing 10, an air guide port 19 is provided in the middle of the first air guide housing 9, and a blower port 16 is provided in the middle of the second air guide housing 7. External airflow enters the natural air guide duct 23 through the passive ventilation port 22, and the airflow in the natural air guide duct 23 enters the internal pressurized air guide duct 24 through the blower pipe 17.

[0047] In this invention, when the vehicle is in motion, the airflow in front enters the natural air duct 23 through the passive ventilation port 22, and the airflow blows towards the mirror surface 2 to remove residual water droplets. When the user starts the mirror holder 4, a high-pressure airflow is generated in the internal pressurized air duct 24. Based on Bernoulli's principle, the low-speed airflow in the natural air duct 23 is drawn out at the intersection 25 of the inner and outer air ducts, realizing the airflow multiplication effect and further enhancing the removal effect of dust and water droplets on the worm gear blower 8.

[0048] The heating defrosting and defogging assembly includes a heating element 3, which is fixedly connected to the rear end of the mirror 2. The heating element 3 can heat the mirror 2 to quickly evaporate fog and melt frost, adapting to various climatic conditions and ensuring that the mirror 2 is clear.

[0049] The nozzle and the demister fluid delivery pipe 11 are in four sets, and one end of each of the four sets of demister fluid delivery pipes 11 is fixedly connected to the four corners of the demister fluid storage tank 5.

[0050] In this invention, four sets of rearview mirror housings 10 are arranged at the four corners of the rearview mirror. This arrangement helps the spray to quickly cover the entire mirror surface 2, forming a uniform liquid film. The airflow direction is designed to converge from the periphery of the mirror surface 2 towards the center, thereby effectively repelling residual droplets and dust and enhancing the synergistic cleaning effect.

[0051] like Figure 6 As shown, the arrows around the internal pressurized air duct 24 indicate the direction of airflow. The right end of the central support shell 6 is fixedly connected to the mounting bracket 26, which is used to install the active anti-fog and rainproof rearview mirror on the car. The right end of the central support shell 6 has a control line channel 13, and the mounting bracket 26 has a clearance hole 27. The control line channel 13 is connected to the clearance hole 27. The control line channel 13 and the clearance hole 27 are used to avoid and accommodate various power and control lines of the active anti-fog and rainproof rearview mirror.

[0052] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
