[0032] A camera device is an electronic device capable of capturing moving images and converting them into digital or analog signals for storage, transmission, or display. By mounting a camera device at the rear of a vehicle, it can play a crucial role in driving safety, accident liability determination, and daily driving record-keeping. In actual production and use, researchers have found that traditional camera devices are prone to fogging on their imaging surfaces, resulting in unclear images. This fogging is particularly severe in low temperatures due to the significant temperature difference between the camera device and the external environment, further exacerbating the problem and significantly affecting the clarity of the captured images.
[0033] This utility model proposes a camera device to solve the technical problem of unclear images caused by fogging in camera devices.
[0034] Please see Figures 1 to 3 In one embodiment of the present invention, the camera device includes a housing 100, a circuit board 200, a camera 300, and a heating cable 400. The circuit board 200 is disposed inside the housing 100, the camera 300 is disposed inside the housing 100 and electrically connected to the circuit board 200, the camera 300 is provided with a shooting surface 310, the shooting surface 310 is exposed outside the housing 100, and at least a portion of the heating cable 400 is wound around the end of the camera 300 near the shooting surface 310, and the heating cable 400 is electrically connected to the circuit board 200.
[0035] The technical solution of this utility model involves heating the camera 300 by wrapping a heating cable 400 around the end of the camera 300 near the shooting surface 310. This heats the camera 300, allowing water vapor adhering to the shooting surface 310 to evaporate in a timely manner, ensuring the clarity of the images captured by the imaging device. In this embodiment, the camera 300 is used to capture images in real time and convert them into digital or analog signals for storage, transmission, or display by electronic devices. By mounting the circuit board 200 and the camera 300 inside the housing 100, they can be better protected, reducing the risk of damage. By wrapping at least a portion of the heating cable 400 around the end of the camera 300 near the shooting surface 310, the camera 300 can be heated to evaporate water vapor adhering to the shooting surface 310, ensuring the clarity of the images captured by the imaging device. Specifically, when water vapor adheres to the imaging surface 310 of the camera 300, by applying current to the heating cable 400, the temperature of the portion of the heating cable 400 wound around the camera 300 can be increased, heating the camera 300 to evaporate the water vapor adhering to the imaging surface 310 of the camera 300, thus ensuring the clarity of the image captured by the imaging device. This camera device is applied in the field of vehicle rear-view camera technology.
[0036] Please see Figure 2 In one embodiment of this utility model, the heating cable 400 includes a winding section 410 and a connecting section 420.

By placing the sealing member 130 in the L-shaped sealing groove 121 and abutting against the bent surface 111, an L-shaped sealing structure can be formed to improve the waterproof performance of the camera device. Specifically, when the cover 120 is installed onto the housing 110, the sealing member 130 will deform due to compression, thereby forming an L-shaped sealing structure. The L-shaped sealing structure can increase the sealing contact area and improve the sealing performance.

The heat-conducting plate 220 and the inner wall of the outer shell 100 form an accommodating gap, and a heat-conducting block 221 is disposed in the accommodating gap. In this embodiment, by providing a heat-conducting block 221 between the heat-conducting plate 220 of the circuit board 200 and the inner wall of the outer shell 100, the heat generated by the circuit board 200 is conducted to the metal outer shell 100, thereby improving the heat dissipation capacity of the camera device. In a specific embodiment, the heat-conducting block 221 is a thermally conductive silicone component, that is, the heat-conducting block 221 is made of thermally conductive silicone.
