Description

Technical Field

[0001] The utility model belongs to the field of vehicle-mounted cameras, and particularly relates to a vehicle-mounted camera structure for preventing being affected by reflected light. Background Art

[0002] The existing filter of the vehicle-mounted camera is directly injection-molded onto the front shell for the second time. When the photosensitive LENS of the vehicle-mounted camera detects that the environment is too dark, the LED lights on the lamp board will light up, and the light will pass through the filter for supplementary lighting. At this time, the light emitted by the LED lights passes through the filter and irradiates onto the high-gloss parts inside the vehicle (such as the high-brightness black reading lamp), and stray light will be reflected back to the lens, affecting imaging and causing the product performance to decline. Summary of the Invention

[0003] In view of the above technical problems and disadvantages, the purpose of the utility model is to provide a vehicle-mounted camera structure for preventing being affected by reflected light. The filter of this structure is detachably installed with the front shell of the camera. The front end of the filter is provided with a light-transmitting area and a light-impermeable area. The light-impermeable area is used for shading to ensure that after the camera is installed on the vehicle, the light emitted by the LED lights does not irradiate onto the high-gloss parts inside the vehicle; the light-transmitting area ensures that the LED light can normally pass through for supplementary lighting. This kind of structure can avoid stray light being reflected back to the lens, causing problems such as poor imaging.

[0004] To achieve the above purpose, the utility model adopts the following technical scheme:

The improvement is that a lamp board installation groove is provided on the front side of the front shell of the camera body. A first positioning pin is provided on the lamp board installation groove. An outer ring of the lamp board installation groove is provided with a filter installation groove. A second positioning pin and at least two threaded holes are provided on the filter installation groove. The depth of the lamp board installation groove is greater than the depth of the filter installation groove; a positioning hole is provided on the lamp board of the camera body at a position opposite to the first positioning pin, and the lamp board is installed in the lamp board installation groove; a positioning hole is provided on the filter of the camera body at a position opposite to the second positioning pin, and an assembly hole is provided at a position opposite to the threaded hole, and the filter is installed in the filter installation groove; the filter includes a fixing frame and a light-transmitting plate provided at the front end of the fixing frame; wherein, a press-fitting avoidance groove is provided on one side of the fixing frame facing the filter installation groove, so that the lamp board is fixed between the front shell and the filter. A light-emitting channel is provided on the fixing frame at a position opposite to the lamp board. The front end of the light-emitting channel is provided with a light-shielding strip near the upper end. A light-transmitting plate is provided outside the light-shielding strip.

[0008] Advantages and beneficial effects of the present utility model:

[0009] (1) The camera structure provided by the present utility model improves the overall structure of the filter. After improvement, the filter (also called the infrared lamp cover) is detachably installed on the front shell of the camera. The front end of the filter forms a light-transmitting area and a light-blocking area by using light-transmitting materials and light-blocking materials. The light-transmitting area ensures that the LED light can normally penetrate for supplementary lighting; the light-blocking area is used for shading to ensure that after the camera structure is installed on the vehicle, the light emitted by the LED does not irradiate the high-brightness components inside the vehicle, avoiding the problem that stray light is reflected back to the lens and causing poor imaging.

[0010] (2) For different vehicle models, the camera structure provided by the present utility model only needs to replace the filter, and the remaining parts remain unchanged, which can solve the technical problem of poor imaging effect caused by reflected light in the existing camera. This can not only shorten the development cycle but also reduce costs such as materials.

[0011] (3) Using the camera structure provided by the present utility model can eliminate the reflected light from inside the vehicle, make the imaging effect of the camera better, reduce customer complaints, reduce after-sales problems, etc., and improve the customer satisfaction and usage experience of the product.
