[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] This utility model provides, for example Figures 1-4 The camera shown is for a streaming media rearview mirror based on dynamic ambient light compensation technology. It includes a housing 1 with a through hole 2. The camera body 3 is fixedly installed inside the through hole 2. The camera body 3 uses dynamic ambient light compensation technology to sense changes in ambient light in real time and dynamically adjust the display or imaging parameters. It is mainly used to improve the adaptability of the visual device under different lighting conditions and is used in conjunction with a streaming media rearview mirror. Dynamic ambient light compensation and its integration with a streaming media rearview mirror are common existing technologies and will not be described in detail here.
[0022] Considering that water droplets are easily left on the shooting end of the camera body 3, especially in rainy or snowy weather, and are difficult to clean in time, posing a safety hazard when reversing, in order to improve the utilization efficiency of the streaming media rearview mirror camera, a recycling chamber 4 is provided on the outer wall of the housing 1. An air box 5 is provided inside the recycling chamber 4. An air outlet 6 is provided on the side of the air box 5 near the camera body 3. When the gas is sprayed out from the air outlet 6, it can be tilted to act on the shooting end of the camera body 3, making it easier to blow away residual water droplets. Multiple air outlets 6 can be provided, and a one-way valve can be provided at the air outlet 6 to prevent rainwater from entering the interior of the air box 5.
[0023] A square groove 7 is provided on the inner wall of the recovery chamber 4. The recovery chamber 4 is connected to the inside of the shell 1 through the square groove 7. A square box 8 is provided inside the square groove 7, and the square box 8 is connected to the air box 5. The square box 8 can move synchronously with the air box 5. When the square box 8 drives the air box 5 to extend outward, air can be blown towards the camera body 3 through the air outlet 6 to blow away residual water droplets on the camera body 3.
[0024] An electric push rod 18 is installed inside the housing 1. One end of the electric push rod 18 is hinged to the inner wall of the housing 1, and the other end of the electric push rod 18 is hinged to the inner wall of the housing 1. When the extension end of the electric push rod 18 is retracted, the square box 8 drives the air box 5 to extend outward; when the extension end of the electric push rod 18 is extended, the air box 5 is retracted into the recovery chamber 4.
[0025] The end of the square box 8 furthest from the air box 5 is connected to an airbag 9, which has a certain degree of elasticity. The end of the airbag 9 furthest from the square box 8 is connected to an air tube 10. In actual use, a miniature air pump (not shown in the figure) can be set up to work with a streaming media rearview mirror camera. The miniature air pump is installed on the vehicle body and can deliver gas into the airbag 9 through the air tube 10.
[0026] A sliding channel 11 is provided on the square box 8, and the sliding channel 11 extends through the upper and lower surfaces of the square box 8. A slider 12 is slidably arranged inside the sliding channel 11, and a through groove 13 that cooperates with the square box 8 is provided on the slider 12.
[0027] A guide block 15 is fixedly connected to the inner wall of the housing 1. A first oblique cut 16 is provided on the slider 12, and a second oblique cut 17 is provided on the guide block 15. The first oblique cut 16 and the second oblique cut 17 cooperate with each other, as shown in the reference. Figure 4 When the square box 8 extends the air box 5 outward, the first oblique cut 16 first contacts the second oblique cut 17, and then the guide block 15 will press the slider 12 to slide downward. In actual use, a ball bearing or other structure can be set on the top of the slider 12 to reduce the friction between the guide block 15 and the slider 12. A bracket is fixedly connected to the outer wall of the square box 8, and the bracket is located on the side of the square box 8 away from the guide block 15. An elastic telescopic rod 14 is fixedly connected to the bracket, and the slider 12 is fixedly connected to the elastic telescopic rod 14.
[0028] When residual water droplets appear on the shooting end of the camera body 3, the driver observes the shadow on the streaming rearview mirror, activates the micro air pump, and delivers gas into the airbag 9 through the air pipe 10. At this time, the through groove 13 is misaligned with the square box 8, and the slider 12 separates the square box 8. The gas accumulates inside the airbag 9, and the airbag 9 inflates. Then, the telescopic end of the electric push rod 18 is retracted, and the square box 8 drives the air box 5 to extend outward. With the cooperation of the first oblique cut 16 and the second oblique cut 17, the guide block 15 will squeeze the slider 12 to slide downward. The through groove 13 is connected to the square box 8, and the gas accumulated inside the airbag 9 enters the air box 5 through the square box 8 and is sprayed towards the shooting end of the camera body 3 through the air outlet 6. The reset elasticity of the airbag 9 can accelerate the gas ejection speed and quickly blow away the residual water droplets.
[0029] After use, the wind box 5 is retracted into the recycling chamber 4. The hidden design does not affect the normal use of the streaming rearview mirror camera.
[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
