Description

Technical Field

[0001] This utility model relates to the field of cameras, and in particular to a camera structure with glass heating function. Background Technology

[0002] In the fields of intelligent driving and security monitoring, the frosting and fogging problems of camera glass have become a key technical bottleneck restricting image quality and equipment reliability. In low-temperature, high-humidity, or rainy / foggy weather, the frost and fog layer formed on the glass surface due to temperature differences or water vapor condensation can cause light scattering, blurred images, and even functional failure, seriously threatening the environmental perception capabilities of intelligent driving systems and the reliability of security monitoring. Current technologies address the frosting and fogging problems of camera glass by arranging printed or etched resistance wires on the waterproof glass of the camera. Current is passed through the resistance wires to heat the waterproof glass, achieving the effect of defrosting and defogging. However, due to uneven temperature distribution on the waterproof glass and exposure to sunlight, the printed or etched resistance wires are at risk of breakage with long-term use, resulting in ineffective defrosting and defogging, thus affecting the camera's image quality and reliability. Utility Model Content

[0003] The purpose of this invention is to provide a camera structure with glass heating function that can effectively defrost and defog, so as to improve the imaging quality and reliability of the camera.

[0004] The camera structure with glass heating function described in this utility model includes a housing, a lens body installed inside the housing, a window for recording and taking pictures on the front of the housing, a waterproof glass installed on the window, a fixing bracket inside the housing, the lens body installed on the back of the fixing bracket, and a through hole reserved on the fixing bracket for the lens body to extend from the back of the fixing bracket to the waterproof glass. A foam gasket is installed at the edge of the through hole on the front of the fixing bracket, and an aluminum base ring is provided in front of the foam gasket, which is pressed against the waterproof glass by the fixing bracket. The front of the aluminum base ring is in close contact with the waterproof glass, and a resistor for heating the waterproof glass is provided on the back of the aluminum base ring.

[0005] The camera structure with glass heating function described in this utility model uses an aluminum base ring, which is pressed against the waterproof glass by the mounting bracket, to be installed at the edge of the through-hole. Heat is generated by the resistance on the back of the aluminum base ring and transferred to the waterproof glass, effectively defrosting and defogging the waterproof glass, thereby improving the imaging quality and reliability of the camera. In addition, installing a foam gasket at the edge of the through-hole on the front of the mounting bracket effectively presses the aluminum base ring against the waterproof glass, further improving the utilization rate of the heat generated by resistance and enhancing the defrosting and defogging of the waterproof glass. Furthermore, the mounting bracket has a through-hole for the lens body to extend from the back of the mounting bracket to the waterproof glass, which can improve the imaging quality and reliability of the camera.

[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] In this utility model, it should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0024] A camera structure with glass heating function, such as Figure 1 - Figure 7 As shown, the device includes a housing 1, a lens body 2 installed inside the housing, a window 3 on the front of the housing for the lens body to record video and take pictures, a waterproof glass 4 installed on the window, a mounting bracket 5 inside the housing, the lens body is installed on the back of the mounting bracket, and a through hole 6 is reserved on the mounting bracket for the lens body to extend from the back of the mounting bracket to the waterproof glass. A foam gasket 7 is installed on the edge of the through hole on the front of the mounting bracket, and an aluminum base ring 8 is provided in front of the foam gasket and pressed against the waterproof glass by the mounting bracket. The front of the aluminum base ring is close to the waterproof glass, and a resistor 9 is provided on the back of the aluminum base ring to heat the waterproof glass.

[0025] The housing includes a front housing 101 and a rear housing 102 that covers the front housing and is then fixed with screws or bolts. This seals the lens body 2, mounting bracket 5, foam gasket 7, and aluminum base plate ring 8 within the housing, thus achieving a waterproof function. The window is located on the front housing. The inner edge of the window on the front housing has a stepped surface 11 that abuts against the waterproof glass. The edge of the waterproof glass has a soft retainer 12 that holds the waterproof glass in place. The soft retainer 12 is a retainer ring made of soft plastic. The waterproof glass is fitted onto the soft plastic retainer ring, and then sealant is applied to press or press it firmly against the stepped surface, achieving a sealing and waterproof effect.

[0026] The front of the mounting bracket has a through-hole edge with a mounting groove 10 for installing a foam gasket and an aluminum base ring. The mounting groove 10 is a recessed stepped surface on the mounting bracket at the edge of the through-hole. The inner holes of the foam gasket and the aluminum base ring are connected to the through-hole, allowing the lens body to extend towards the waterproof glass. The foam gasket is made of ethylene-vinyl acetate copolymer (EVA), which has the characteristics of high temperature resistance, good compressibility, and good insulation. Its high temperature resistance (thermal decomposition temperature) is between 230 and 250°C. The heat generated by the resistance is transferred to the waterproof glass at a temperature between 35 and 40°C for defrosting and defogging. One side of the foam gasket is covered with double-sided adhesive, which adheres firmly to the recessed stepped surface on the mounting bracket at the edge of the through-hole. The other side is in direct contact with the aluminum base ring, ensuring that the aluminum base ring is tightly attached to the waterproof glass.

[0027] Eight resistors are arranged around an aluminum substrate ring, ensuring more even heat transfer from the ring to the waterproof glass and improving defrosting and defogging performance. The resistors are soldered to the aluminum substrate ring, which is then coated with thermally conductive silicone sealant and pressed firmly onto the waterproof glass.

[0028] A supplementary light 13 and a photoresistor extending towards the waterproof glass are provided between the lens body and the mounting bracket. In low light conditions, the supplementary light not only improves the image quality and reliability of the camera at night, but also generates heat to defrost and defog the waterproof glass. The mounting bracket has a supplementary light through-hole 14 for the supplementary light to extend into the waterproof glass. The supplementary light is mounted on a supplementary light circuit board 15, which is screwed onto the mounting bracket. Additionally, a lens body circuit board 16 is located on the back of the lens body 2, which is screwed onto the lens body 2. The four corners of the lens body circuit board are screwed onto the mounting bracket. Furthermore, the mounting bracket is bolted or screwed to the front housing 101, thereby securing the aluminum substrate ring tightly to the waterproof glass. The mounting bracket also has four support pillars 17 protecting the lens body 2, located at the four corners of the mounting bracket with the lens body 2 in the middle position. These four support pillars 17 serve to fix and protect the lens body.

[0029] The above embodiments are only used to illustrate the detailed solution of this utility model. This utility model is not limited to the above detailed solution, that is, it does not mean that this utility model must rely on the above detailed solution to be implemented. Those skilled in the art should understand that any improvement to this utility model, equivalent substitution of the raw materials of this utility model product, addition of auxiliary components, selection of specific methods, etc., all fall within the protection scope and disclosure scope of this utility model.
