Description

Technical Field

[0001] This utility model relates to the field of monitoring equipment, specifically to a monitoring camera with a protective lens function, which is particularly suitable for maintaining stable monitoring performance under harsh weather conditions such as low temperature and rain / snow. Background Technology

[0002] In the practical application of existing surveillance cameras, low temperatures often bring many problems to the monitoring work. In cold environments, the camera lens is prone to fogging due to temperature differences, resulting in blurry monitoring images and seriously affecting the monitoring effect. In addition, when it snows, snowflakes accumulate on the lens and obstruct the view. Conventional cleaning methods are difficult to deal with effectively, and may even cause the cleaning components to freeze and fail to work properly. Therefore, developing a surveillance camera that can keep the lens clear and work stably in severe weather is of great practical significance. Summary of the Invention

[0003] The purpose of this utility model is to provide a structural design that solves the problems of camera lens fogging and snow obstruction in low-temperature weather through heating and cleaning, thereby addressing the problems existing in the prior art. To achieve the above objective, the specific technical solution of this utility model is as follows: A surveillance camera with a protective lens function includes a main unit, a bracket for adjusting the camera angle installed on the main unit, a monitoring body inside the main unit, an upper shell covering the monitoring body, a lens mounted on the upper shell, a heat insulation component inside the upper shell, and the heat insulation component connected to the lower shell. The heat insulation component includes a rubber body, the front of the rubber body tightly fitting the inner edge ring of the lens, and the back of the rubber body having an inner mating concave surface. The rubber body and a fixing body are fixed by strong pressure. The fixing body has an outer mating convex surface, on which a heating coil is fitted. A heating conductor is connected to the fixing body. The inner mating concave surface and the outer mating convex surface are coupled to fix the heating coil between the rubber body and the fixing body. The fixing body is fixed to the lower shell and the upper shell respectively by inner and outer columns.

[0004] Preferably, the main unit is equipped with a control motor, and the main unit is provided with a brush strip for cleaning the mirror surface. The control motor is connected to the brush strip through a rotating shaft. A brush body rubber is installed on the brush strip, and a brush strip heating wire is inserted inside the brush body rubber. A connecting hole is provided on the brush strip, and a brush strip conductor is provided inside the main unit. The brush strip conductor is electrically connected to the brush strip heating wire, and the brush strip heating wire is embedded in the brush body rubber after passing through the connecting hole.

[0005] Preferably, the host is equipped with a temperature sensor and a control board is installed inside the host. The control board is electrically connected to the brush strip conductor, the temperature sensor, the insulation component and the monitoring unit respectively. The brush strip is used to remove dust, snow and frost from the mirror surface.

[0006] Preferably, the heating element is energized to activate the heating coil, and heat is transferred sequentially to the rubber body and the mirror surface to prevent the mirror surface from fogging in cold weather and from melting rain and snow.

[0007] Preferably, when the temperature sensor detects a low temperature, the control board controls the heating element to be powered on and activates the insulation component. When the mirror is covered by snow or there is dust on the outside of the mirror, the control board can be manually activated by a switch to drive the brush bar motor to work, and the heating wire of the brush bar will heat up at the same time.

[0008] Preferably, the rubber body and brush body rubber are made of a high-temperature resistant material.

[0009] The beneficial effects of this utility model are as follows:

[0010] Highly efficient defogging ensures clear images: Through a uniquely designed insulation component, the heating coil operates in cold weather, transferring heat sequentially through the rubber body to the mirror surface. This prevents the mirror temperature from becoming too high or too low, effectively preventing fogging. This feature allows the surveillance camera to continuously provide clear monitoring images in low-temperature environments, avoiding blind spots caused by blurred mirrors. It significantly improves the effectiveness and reliability of monitoring, meeting the demand for clear images in scenarios such as outdoor security and industrial monitoring during cold seasons.

[0011] Powerful cleaning to handle complex weather: The motor-driven brush bar, in conjunction with the brush body rubber and internal brush bar heating wire, not only removes dust from the lens surface under normal conditions, keeping the lens clean; but also, in rainy or snowy weather, the heating wire melts the rain and snow, preventing the brush bar from freezing and becoming inoperable. This gives the surveillance camera the ability to cope with complex and severe weather, ensuring normal operation under various extreme weather conditions and guaranteeing the continuity of monitoring work.

[0012] Flexible configuration to adapt to different environments: This invention offers high flexibility in configuration. For environments with relatively good conditions and primarily affected by low temperatures, only the insulation component can be used, with the heated mirror surface preventing fogging, thus meeting basic low-temperature protection requirements at a lower cost. For areas with relatively harsh environments prone to dust, rain, snow, and other complex conditions, the brush strip heating configuration can be activated to enhance cleaning and de-icing / snow melting capabilities. Both configurations can be used simultaneously; if one function fails, the other can still ensure stable operation of the surveillance camera, greatly improving the device's environmental adaptability and overall reliability.

[0013] Intelligent control enhances the user experience: The temperature sensor on the main unit works in conjunction with the control board. When the temperature sensor detects a low temperature, it can automatically trigger the insulation components to work without manual intervention, achieving intelligent temperature regulation. In special weather conditions such as snow, the motor and brush heating wire can be controlled manually via the control board to promptly remove obstructions from the mirror surface, greatly improving the ease of use and user experience of the equipment and reducing manual maintenance costs.

[0019] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings. Specific examples will be used to illustrate the implementation of this disclosure. Those skilled in the art can easily understand other advantages and effects of this disclosure from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. Further explanation will follow with reference to the accompanying drawings.

[0020] See Figure 1-4 As can be seen, in a preferred embodiment of the present invention, a surveillance camera with a protective lens function includes a host 1, a mirror 5 on the host 1, a bracket 3 for adjusting the camera angle on the host 1, a control motor 4 on the host 1, and a brush strip 2 for cleaning the mirror 5 installed on the control motor 4.

[0021] Furthermore, the main unit 1 contains a monitoring body 8, which has an upper shell 6. The mirror 5 is mounted on the upper shell 6. The upper shell 6 contains a heat insulation component 9, which is connected to the lower shell 7. The heat insulation component 9 includes a rubber body 10 and a fixing body 14 that is fixed to the rubber body 10 by a strong pressure method. The front of the rubber body 10 fits against the edge of the mirror 5, and the back has an inner mating concave surface 11. The fixing body 14 has a corresponding outer mating convex surface 15. A heating coil 12 is fitted on the outer mating convex surface 15. The inner mating concave surface 11 and the outer mating convex surface 15 are coupled to fix the heating coil 12 between the rubber body 10 and the fixing body 14. The fixing body 14 has a heating conductor 13 that is electrically connected to the heating coil 12. The fixing body 14 also has an inner column and an outer column. The outer column is fixed to the upper shell 6, and the inner column is fixed to the lower shell 7. When the heating element 13 is powered on, the current is conducted through it to the heating coil 12, causing the heating coil 12 to generate heat, which is then transferred to the rubber body 10 in contact with it, and then conducted from the rubber body 10 to the mirror surface 5, thereby maintaining the temperature stability of the mirror surface 5. This process effectively prevents the mirror surface 5 from fogging due to low temperature in cold weather, ensuring that the mirror surface is always clear and guaranteeing the stable operation of the surveillance camera.

[0022] Furthermore, the control motor 4 is provided with a rotating shaft 19, which is connected to the brush strip 2. The brush strip 2 is connected to the control motor 4 through the rotating shaft 19. The brush strip 2 is equipped with a brush body rubber 17, and a brush strip heating wire 16 is inserted into the brush body rubber 17. The brush strip 2 is provided with a connecting hole 18. The main unit 1 is provided with a brush strip conductor 20, which is electrically connected to the brush strip heating wire 16. The brush strip heating wire 16 passes through the connecting hole 18 and is inserted into the brush body rubber 17.

[0023] Furthermore, a temperature sensor is installed on the host unit 1, and a control board is located inside the host unit 1. The control board is electrically connected to the brush conductor 20, the temperature sensor, the insulation component 9, and the monitoring unit 8. In operation, the control board first controls the monitoring unit 8 to start running. When the temperature sensor detects a low ambient temperature, the insulation component 9 will activate to prevent fogging of the mirror 5, ensuring its clarity and providing a guarantee for the stable operation of the monitoring camera. In snowy weather, if the mirror 5 is obscured by snow, the control board can control the insulation component 9 to drive the control motor 4 to operate the brush strip 2. When the brush strip 2 is running, its built-in brush strip heating wire 16 will heat up simultaneously, allowing the brush strip 2 to melt the rain and snow obstructing the mirror surface. At the same time, the heating of the brush strip heating wire 16 can prevent the brush strip 2 from freezing due to the low temperature of rain and snow, preventing it from becoming inoperable. In daily use, the brush strip 2 can also remove dust from the outside of the mirror 5. Through this dual heating combination of internal insulation and external brush strip heating, the problem of unclear mirror 5 can be quickly solved.

[0024] The internal and external protective lens functions enable the surveillance camera to adapt to low-temperature weather and work stably. In terms of configuration, only one function can be used. For example, in relatively good environments, only the heat preservation component 9 configuration can be used. If the environment is relatively poor, the brush strip heating configuration can be used. Of course, if both configurations are used together, the other can still allow the surveillance camera to work stably if one of them has a problem.

[0025] In summary, the above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
