Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted cameras, in particular to an anti-collision device for a vehicle-mounted camera. Background Art

[0002] At present, the commonly used car camera structure generally includes the lens, the shell and the PCB board with the photosensitive element and other main parts. The car camera refers to the function of presenting video and audio in real time, which provides a more scientific basis for the handling and positioning of traffic accidents, and fully protects our property and life safety. The car camera provides reliable evidence for the analysis and judgment of traffic accidents. Car cameras include two types installed inside the car body and outside the car body.

[0003] Existing vehicle-mounted cameras installed on the outside of the vehicle body are often impacted by foreign objects during vehicle driving, which may cause damage to the camera body, affect the camera's shooting effect, and cause the camera to be unable to be used normally. Utility Model Content

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing technology and provide an anti-collision device for a vehicle-mounted camera, so as to solve the problem in the existing technology that the camera body is often impacted by foreign objects during the driving of the vehicle, thereby affecting the shooting effect of the camera and causing the camera to be unable to be used normally.

[0005] In view of this, the present invention provides an anti-collision device for a vehicle-mounted camera, comprising a housing, a camera body being fixedly mounted inside the housing, and an anti-collision mechanism being provided inside the housing;

[0006] The anti-collision mechanism includes a protective part, a movable part and a sealing ring. A movable cavity is opened inside the shell. The movable part is slidably connected inside the shell. The sealing ring is fixedly installed on the side wall of the movable part. There are several sealing rings. The protective part is fixedly installed on the top of the movable part. The protective part is located on one side of the camera body.

[0007] Optionally, the interior of the protective element is filled with an inert gas, wherein the inert gas may be helium, neon or argon.

[0008] Optionally, the movable cavity is an annular cavity, and the movable part is an annular part.

[0009] Optionally, a mounting bracket is fixedly mounted on the side wall of the shell, and a mounting hole is provided inside the mounting bracket.

[0010] Optionally, the protective element consists of a wear-resistant layer, a light-transmitting layer and a protective layer.

[0011] Optionally, the wear-resistant layer is made of thermoelastic polyurethane.

[0012] It can be seen from the above technical solutions that the embodiments of the present invention have the following advantages:

[0013] 1. The utility model is an anti-collision device for a vehicle-mounted camera, which adopts an anti-collision mechanism. By arranging a protective part on the top of the movable part, the protective part can wrap and protect the camera body. When the protective part is subjected to an external collision, it drives the movable part to slide inside the movable cavity. At this time, the air inside the protective part is compressed and then recovered, playing a certain buffering role, thereby better protecting the camera body and preventing the camera body from being hit.

[0014] 2. The utility model is an anti-collision device for a vehicle-mounted camera, which adopts a wear-resistant layer design. Such a design can reduce scratches on the protective part and avoid affecting the shooting effect of the camera body.

[0015] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following is an explanation and description of the technical solutions of the embodiments of the present invention in conjunction with the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0023] An anti-collision device for a vehicle-mounted camera according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0024] Example 1

[0025] For easier understanding, see Figures 1 to 4 The utility model provides an embodiment of an anti-collision device for a vehicle-mounted camera, comprising a housing 1, a camera body 4 is fixedly mounted inside the housing 1, and an anti-collision mechanism is provided inside the housing 1;

[0026] The anti-collision mechanism includes a protective part 3, a movable part 6 and a sealing ring 7. A movable cavity 5 is opened inside the shell 1. The movable part 6 is slidably connected inside the shell 1. The sealing ring 7 is fixedly installed on the side wall of the movable part 6. There are several sealing rings 7. The protective part 3 is fixedly installed on the top of the movable part 6. The protective part 3 is located on one side of the camera body 4. The movable cavity 5 is an annular cavity and the movable part 6 is an annular part.

[0027] It should be noted that, by providing the movable cavity 5, the movable part 6 can slide inside the movable cavity 5, and by providing the protective part 3 on the top of the movable part 6, the protective part 3 can wrap and protect the camera body 4, and form a nearly sealed space between the protective part 3 and the surface of the shell 1. When the protective part 3 is subjected to an external collision, it drives the movable part 6 to slide inside the movable cavity 5. At this time, the air inside the protective part 3 is compressed and then recovered, which plays a certain buffering role, thereby better protecting the camera body 4 and preventing the camera body 4 from being hit.

[0028] In some embodiments, as Figure 2 As shown, the interior of the protective member 3 is filled with an inert gas, wherein the inert gas can be helium, neon or argon.

[0029] It should be noted that by providing an inert gas inside the protective member 3 , the lens inside the camera body 4 is prevented from being damaged by oxidation, thereby ensuring the shooting effect of the camera body 4 .

[0030] In some embodiments, as Figure 1 As shown, a mounting bracket 2 is fixedly mounted on the side wall of the housing 1 , and a mounting hole is provided inside the mounting bracket 2 .

[0031] It should be noted that, by providing the mounting bracket 2 with mounting holes, the housing 1 can be mounted at a desired location using bolts.

[0032] Example 2

[0033] In some embodiments, as Figure 4 As shown, the protective member 3 is composed of a wear-resistant layer 8, a light-transmitting layer 9 and a protective layer 10. The wear-resistant layer 8 is made of thermoelastic polyurethane.

[0034] It should be noted that, by providing the wear-resistant layer 8 , the wear-resistant effect of the protective element 3 can be increased, scratches on the protective element 3 can be reduced, and the impact on the shooting effect of the camera body 4 can be avoided.

[0035] The camera body 4 in the present invention is a well-known component and will not be described in detail here.

[0036] Working principle: When the protective part 3 is subjected to external collision, the air inside the protective part 3 is compressed and then recovered, playing a certain buffering role. At this time, the movable part 6 will slide inside the movable cavity 5 and play a damping effect through the sealing ring 7, thereby better protecting the camera body 4 and preventing the camera body 4 from being hit.

[0037] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
