[0021] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0022] The rearview mirror and vehicle of the embodiment of the utility model are described below with reference to the accompanying drawings. In view of the problem mentioned in the background technology that the scheme for removing rainwater from the rearview mirror in the prior art cannot achieve a good water removal effect when the rain is heavy, the utility model provides a rearview mirror, in which the current rainfall mode, the current wind direction and the current wind speed are detected by a detection component, and the airflow generating component is controlled by a control component to generate an airflow to the lens according to the current rainfall mode, the current wind direction and the current wind speed. Thus, the problem that the scheme for removing rainwater from the rearview mirror in the prior art cannot achieve a good water removal effect when the rain is heavy is solved, and the direction and speed of the airflow output to the air barrier of the rearview mirror can be intelligently adjusted according to the size of the rain, the direction of the environment and the wind speed, and the rearview mirror can further achieve a clear view of the oncoming vehicle behind in the rain.

[0023] Specifically, Figure 1 The present invention is a block diagram of a rearview mirror provided in an embodiment of the present invention.

[0024] like Figure 1 As shown, the rearview mirror 10 includes: a housing 100 and a lens 200 disposed in the housing, an airflow generating member 300 , a detecting member 400 and a controlling member 500 .

[0025] Among them, the detection component 400 detects the current rainfall pattern, the current wind direction and the current wind speed; the control component 500 is respectively connected to the detection component 400 and the airflow generating component 300, and the control component 500 controls the airflow generating component 300 to generate airflow to the lens 200 according to the current rainfall pattern, the current wind direction and the current wind speed.

[0026] In some embodiments, the lens 200 is a reflective lens.

[0027] In some embodiments, the detection element 400 is disposed on the outer wall of the housing, and / or the surface of the lens, and / or the surface of the front windshield of the vehicle.

[0028] It can be understood that the detection element 400 can be set on the outer wall of the shell, or on the lens surface, or on the front windshield surface of the vehicle, or the detection element 400 can be set on the outer wall of the shell, the lens surface, and the front windshield surface of the vehicle.

[0029] In some embodiments, the airflow generating member 300 is a motor or a blower.

[0030] Optionally, in some embodiments, the detection unit 400 includes: a first detection unit, a second detection unit and a third detection unit. The first detection unit is connected to the control unit 500, and the first detection unit detects the current rainfall mode; the second detection unit is connected to the control unit 500, and the second detection unit detects the current wind speed; the third detection unit is connected to the control unit 500, and the third detection unit detects the current wind direction.

[0031] In some embodiments, the first detection unit is a rainfall sensor, the second detection unit is an ultrasonic wind speed sensor, and the third detection unit is a wind direction sensor.

[0032] In the embodiment of the utility model, the current rainfall mode is measured by installing a rain sensor on the front windshield of the car. When there are raindrops on the outer surface of the windshield, the light incident on the windshield is partially scattered, and the light of the receiving tube becomes less after reflection. The greater the rainfall, the less light is reflected back. By comparing the received light intensity with the windshield when it is dry, the size and amount of water drops on the windshield at this time can be obtained, and then different rain modes can be judged, including light rain mode, moderate rain mode, and heavy rain mode.

[0033] Detection principle of wind speed and wind direction: The working principle of ultrasonic wind measurement is to use the ultrasonic time difference method to realize the measurement of wind speed and wind direction by ultrasonic wind speed sensor and wind direction sensor. Due to the propagation speed of sound in the air, it will be superimposed with the airflow speed in the wind direction. If the propagation direction of the ultrasonic wave is the same as the wind direction, then its speed will increase; conversely, if the propagation direction of the ultrasonic wave is opposite to the wind direction, then its speed will slow down. Therefore, under fixed detection conditions, the propagation speed of the ultrasonic wave in the air can correspond to the wind speed function, and the accurate wind speed and wind direction can be obtained by calculation.

[0034] Furthermore, the controller (ie, the control element 500 ) controls a high-power motor or blower, which can generate a sufficiently strong air flow velocity.

[0035] Optionally, in some embodiments, the above-mentioned rearview mirror 10 further includes: an air guide hole 600 disposed in the shell; and a first adjustment member, the first adjustment member adjusting the outlet air flow direction of the air guide hole 600 .

[0036] Specifically, an air outlet guide device with adjustable direction is installed in the shell of the rearview mirror. By adjusting the outlet airflow direction of the guide hole 600 by the first adjustment member, airflow in different directions can be output, so that the airflow barrier generated by the high-speed airflow prevents rainwater from entering the protective area on the surface of the rearview mirror lens.

[0037] Optionally, in some embodiments, the airflow generating member 300 further includes: a second adjusting member, the second adjusting member is connected to the control member 500 , and the second adjusting member adjusts the airflow speed of the airflow generating member 300 .

[0038] Specifically, the airflow generating member 300 is provided with a second adjusting member, and the control member 500 can adjust the airflow speed of the airflow generating member 300 through the second adjusting member.

[0039] Optionally, in some embodiments, the detection component 400 further includes: a fourth detection unit, the fourth detection unit is connected to the control component 500, and the control component 500 reduces the current airflow speed of the airflow generating component 300 to a preset airflow speed when the fourth detection unit detects that the current rainfall is less than or equal to a preset threshold.

[0040] The preset threshold may be a threshold set in advance by a user, a threshold obtained through a limited number of experiments, or a threshold obtained through a limited number of computer simulations, which is not specifically limited here.

[0041] It should be understood that the detection member 400 is provided with a fourth detection unit, and when the fourth detection unit detects that the current rainfall is less than or equal to a preset threshold, the current airflow speed of the airflow generating member 300 is reduced to a preset airflow speed to reduce energy consumption.

[0042] In order to enable those skilled in the art to further understand the rearview mirror of the embodiment of the utility model, it is described in detail below in conjunction with specific embodiments.

[0043] The overall working principle of the intelligent system is: Figure 2 As shown, when the vehicle is driving and encounters rainy weather, the rain sensor detects the amount of rainfall and sends it to the controller. At the same time, the ultrasonic wind speed and wind direction sensors detect the relative wind speed and direction when the vehicle is driving and send them to the controller. The controller comprehensively calculates and determines whether the starter motor or blower starts running and generates high-speed airflow, and at the same time adjusts the airflow direction of the rearview mirror guide hole to the optimal direction, so that the airflow barrier generated by the high-speed airflow will prevent rain from entering the rearview mirror lens protection area.

[0044] The principle of adaptive adjustment: sensors continuously monitor changes in rain and wind speed, the ultrasonic system detects the relative wind speed and direction when the vehicle is driving, and the speed control system automatically adjusts the speed and direction of the fan output to the protected area of ​​the rearview mirror to adapt to different weather conditions and rain intensity, ensuring efficient and continuous operation in different situations to maintain the airflow barrier until the rain stops or decreases to an acceptable level. Once the rain stops, the speed control system can reduce the speed of the fan to reduce energy consumption.

[0045] According to the rearview mirror proposed in the embodiment of the utility model, the current rainfall mode, the current wind direction and the current wind speed are detected by the detection part, and the airflow generating part is controlled by the control part to generate airflow to the lens according to the current rainfall mode, the current wind direction and the current wind speed. Thus, the problem that the solution for removing rainwater from the rearview mirror in the prior art cannot achieve a good water removal effect when the rainwater is heavy is solved. It does not require the driver to turn on the automatic rearview mirror heating function or manually click the automatic heating function of the rearview mirror. It can intelligently adjust the direction and speed of the airflow output to the rearview mirror air barrier according to the size of the rainwater, the direction of the environment and the wind speed, and further realize that the rearview mirror can clearly see the oncoming vehicles behind in the rainy situation.
