Description

Technical Field

[0001] This utility model relates to the field of camera accessory technology, and in particular to a lightweight camera cover. Background Technology

[0002] In today's digital age, the application scenarios of cameras are constantly expanding, and the performance requirements for camera covers are also increasing. As cameras are deeply integrated into scenarios such as intelligent monitoring in the security field, electronic police capture in urban traffic, remote care in home scenarios, and equipment inspection in industrial production, camera covers, as key protective components to ensure image clarity and equipment durability, have different requirements for the protection level and environmental adaptability of protective covers in different application environments, from extremely cold snow regions to high-temperature deserts, from high-humidity coastal areas to strong wind and sand mining areas. This has driven the industry to continuously explore materials science and structural design.

[0003] In actual use, due to changes in ambient temperature or the heat generated by the camera itself during operation, a significant temperature difference is created between the inside of the cover and the outside. Moisture in the air easily condenses inside the cover, forming fog. This fog adheres to the camera lens or the transparent viewing parts of the cover, severely obstructing the camera's field of view, resulting in blurry images, reduced clarity, and even the inability to obtain effective monitoring or shooting information at critical moments, causing great trouble for security monitoring, outdoor shooting, and other scenarios. Utility Model Content

[0004] The purpose of this utility model is to address the following shortcomings in the existing technology: During actual use, due to changes in ambient temperature or the heat generated by the camera itself during operation, a significant temperature difference is formed between the inside of the cover and the outside. Moisture in the air easily condenses inside the cover to form fog. This fog adheres to the camera lens or the transparent observation component of the cover, which severely obstructs the camera's field of view, resulting in blurry images, reduced clarity, and even the inability to obtain effective monitoring or shooting information at critical moments. This causes great trouble for security monitoring, outdoor shooting, and other scenarios. Therefore, a lightweight camera cover is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A lightweight camera cover includes a camera body and a cover body, wherein the cover body is mounted on the camera body by a clamping assembly, and a rubber sealing ring is installed at one end of the cover body; An installation ring is fixedly installed on the inner wall of the enclosure, and a ring-shaped heating wire is fixedly installed on the installation ring. A temperature sensor is fixedly installed on the inner wall of the enclosure. An installation bracket is fixedly installed on the outer side of the enclosure, and a power module is installed on the installation bracket. The power module, the temperature sensor, and the heating wire are electrically connected by wires.

[0006] Preferably, a ventilating pipe is installed on the top of the cover, and a one-way breathable membrane is fixedly installed inside the ventilating pipe.

[0007] Preferably, the clamping assembly includes two support rods symmetrically fixedly installed on the side of the cover, two movable blocks respectively slidably sleeved on the two support rods, two screws respectively fixedly installed on the two movable blocks, and two clamping blocks respectively sleeved on the two screws. An adjustment assembly for driving relative movement between the two clamping blocks is provided, and nuts are threaded onto both screws.

[0008] Preferably, the adjustment assembly includes a mounting base, an adjusting threaded rod with opposite helical directions at its left and right ends, which is horizontally rotatably mounted on the mounting base, an adjusting block fixedly mounted on one end of the adjusting threaded rod, and two symmetrical movable seats threaded onto the adjusting threaded rod. The mounting base has a strip-shaped hole, the adjusting threaded rod is horizontally rotatably mounted in the strip-shaped hole, and the two movable seats are horizontally slidably mounted in the strip-shaped hole. The two clamping blocks are respectively fixedly connected to the two movable seats.

[0009] Preferably, a stop block is fixedly installed at one end of each of the two support rods, and the diameter of the stop block is larger than the diameter of the support rod.

[0010] Preferably, the power module includes a lithium battery and a control circuit board. The control circuit board integrates an STM32 series microcontroller. The signal output terminal of the temperature sensor is connected to the ADC sampling pin of the microcontroller. The PWM output pin of the microcontroller is connected to the heating wire through a MOSFET driving circuit.

[0011] The beneficial effects of this utility model are as follows: 1. With the help of a temperature sensor, the internal temperature of the cover can be monitored in real time. When the ambient temperature difference causes the risk of water vapor condensation, the heating wire will automatically start heating. By increasing the internal temperature of the cover, the temperature difference can be eliminated, which will suppress the formation of fog from the source and prevent the lens or transparent observation parts from being blocked. This ensures that the camera can maintain a clear shooting field of view in different temperature and humidity environments, and solves the core problem of blurry images caused by fog in traditional camera covers. 2. The clamping components allow the cover to fit camera bodies of different sizes and specifications, making it suitable for cameras in various scenarios such as security monitoring, home care, and industrial inspection. The overall structure adopts a lightweight design, and the connection of each component is simple, making it easy to install, disassemble, and maintain, effectively improving the portability of the camera cover.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figures 1-2 A lightweight camera cover includes a camera body 1 and a cover 2. The cover 2 is mounted on the camera body 1 by a clamping assembly. A rubber sealing ring 3 is installed at one end of the cover 2. The cover 2 serves as a protective structure for the camera body 1. The clamping assembly enables a detachable connection between the cover 2 and the camera body 1, facilitating installation and maintenance. The rubber sealing ring 3 fits against the camera body 1 or the mounting surface, reducing the entry of external moisture, dust, and other impurities into the cover 2, improving the overall sealing and protection performance, and preventing impurities from adhering to the lens and affecting image formation.

[0016] Reference Figures 4-5 A mounting ring 4 is fixedly installed on the inner wall of the cover 2, and a ring-shaped heating wire 5 is fixedly installed on the mounting ring 4. A temperature sensor 6 is fixedly installed on the inner wall of the cover 2. A mounting bracket 7 is fixedly installed on the outer side of the cover 2, and a power module 8 is installed on the mounting bracket 7. The power module 8 includes a lithium battery and a control circuit board. An STM32 series microcontroller is integrated on the control circuit board. The signal output terminal of the temperature sensor 6 is connected to the ADC sampling pin of the microcontroller. The PWM output pin of the microcontroller is connected to the heating wire 5 through a MOSFET drive circuit. The connections of the lithium battery, control circuit board, and circuit are not shown in the figure, as they are prior art and will not be described in detail here. Refer to [reference needed]. Figure 6 .

[0017] The mounting ring 4 provides a fixed carrier for the heating wire 5, ensuring that the heating wire 5 is distributed in a ring shape within the cover 2 to achieve uniform heating. The temperature sensor 6 monitors the internal temperature of the cover 2 in real time. When it detects a temperature difference between the inside and outside that may cause water vapor condensation, it transmits the signal to the power module 8 through a wire. The power module 8 supplies power to the heating wire 5, and the heating wire 5 heats up, raising the internal temperature of the cover 2, eliminating the temperature difference to suppress fog formation. The mounting bracket 7 is used to fix the power module 8, ensuring the stable installation of the power module 8 and ensuring the continuous operation of the power supply system.

[0018] The temperature sensor 6 monitors the temperature inside the enclosure in real time, and the STM32 microcontroller in the power module 8 forms a closed-loop control to achieve an intelligent response of "temperature difference trigger - precise heating - stop heating", thus eliminating the temperature difference conditions for fog formation at the source.

[0019] A vent pipe 9 is installed on the top of the cover 2, and a one-way breathable membrane 10 is fixedly installed inside the vent pipe 9. The vent pipe 9 provides a passage for air circulation inside the cover 2. When the heating wire 5 is working and the air inside the cover 2 is heated and expanded, the air can be discharged through the one-way breathable membrane 10, which avoids the internal air pressure from being too high and damaging the sealing performance of the rubber sealing ring 3. At the same time, the one-way breathable membrane 10 can prevent external moisture and dust from entering the cover 2 in the reverse direction, achieving a dynamic balance between sealing and ventilation, and further reducing the risk of fogging.

[0020] Reference Figure 3 The clamping assembly includes two support rods 11 symmetrically fixedly installed on the side of the cover 2, two movable blocks 12 respectively slidably sleeved on the two support rods 11, two screws 13 respectively fixedly installed on the two movable blocks 12, and two clamping blocks 14 respectively sleeved on the two screws 13. An adjustment assembly for driving relative movement is provided between the two clamping blocks 14. Nuts 15 are threaded onto both screws 13. The adjustment assembly includes a mounting base 16, an adjusting threaded rod 17 with opposite helical directions at the left and right ends, which is horizontally rotatably installed on the mounting base 16, an adjusting block 18 fixedly installed on one end of the adjusting threaded rod 17, and two movable seats 19 symmetrically threaded onto the adjusting threaded rod 17. A strip-shaped hole is opened on the mounting base 16. The adjusting threaded rod 17 is horizontally rotatably installed in the strip-shaped hole. The two movable seats 19 are horizontally slidably installed in the strip-shaped hole. The two clamping blocks 14 are fixedly connected to the two movable seats 19 respectively.

[0021] Mounting base 16 provides a mounting foundation for adjusting threaded rod 17 and movable seat 19. The strip hole restricts the movement trajectory of movable seat 19, ensuring its stable sliding in the horizontal direction. Rotating adjusting block 18 can drive adjusting threaded rod 17 to rotate horizontally within the strip hole. Since the two movable seats 19 are symmetrically threaded onto adjusting threaded rod 17, when adjusting threaded rod 17 rotates, it will drive the two movable seats 19 to move closer to each other along the strip hole, thereby driving the two clamping blocks 14 to move relative to each other, thus clamping the camera body 1 and adapting to the installation requirements of cameras of different sizes. When the two clamping blocks 14 are installed on the camera body 1, the two screws 13 are respectively installed on the two clamping blocks 14, and at the same time, the cover 2 is placed on the lens of the camera body 1. Then, the nut 15 is tightened on one end of the screw 13, so that the nut 15 contacts the clamping block 14, thereby installing the cover 2 on the two clamping blocks 14 through screw 13 and support rod 11. The overall structure adopts a lightweight design, and the connection of each component is simple, which is convenient for installation, disassembly and daily maintenance.

[0022] Both support rods 11 are fixedly equipped with a stop block 20 at one end. The diameter of the stop block 20 is larger than the diameter of the support rod 11. The stop block 20 can prevent the moving block 12 from sliding off the end when it slides along the support rod 11, thus preventing the moving block 12 from detaching from the support rod 11 and causing the clamping assembly to fail, and ensuring the structural stability of the clamping assembly.

[0023] In this invention, the temperature sensor 6 monitors the internal temperature of the cover 2 in real time. When the temperature sensor 6 detects that the internal temperature of the cover is more than 3°C lower than the ambient dew point temperature, the microcontroller outputs a PWM signal with a duty cycle of 50% to control the heating wire 5 to work at half power. When the temperature difference is less than 1°C, heating stops. Through this control logic, the heating wire 5 can accurately adjust the internal temperature of the cover 2, eliminate temperature differences to suppress fog formation, prevent the lens or transparent observation components from being blocked, and ensure that the camera can maintain a clear shooting field of view under different temperature and humidity environments. This solves the core problem of blurred images caused by fog in traditional camera covers.

[0024] 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.
