Description

Technical Field

[0001] The utility model relates to the field of audio and video recorders, and in particular to an audio and video recorder with mechanical automatic focusing. Background Art

[0002] A body camera is a portable electronic device commonly used by police officers, security personnel, and other law enforcement agencies to record them performing their duties. These devices are typically affixed to uniforms to capture and record video and audio to promote fair and transparent law enforcement practices, reduce disputes and misunderstandings, and provide objective evidence for courts and internal reviews.

[0003] However, there are some problems in the actual working process of the existing audio and video law enforcement recorders. For example, a recorder with an automatic focus function with a publication number of CN216414443U can adjust the angle of the camera during work, but it cannot provide convenient and stable protection for the external camera after work. Therefore, the camera is easily damaged by bumps, and its practicality and safety are poor; and an anti-vibration automatic focus law enforcement recorder with a publication number of CN213930048U can effectively reduce the vibration force in all directions that may be brought to the recorder during use during work, and prevent its internal precision parts from being damaged due to excessive vibration. However, in the actual working process, when it encounters backlight conditions, the captured picture will be black and shadows will be easily formed. Therefore, we have made improvements to this and proposed an audio and video recorder with mechanical automatic focus. Utility Model Content

[0036] Example 2:

[0037] The solution in Example 1 is further introduced below in conjunction with a specific working method, as described below:

[0038] like Figure 3 Figure 6 and Figure 7 As shown, as a preferred embodiment, on the basis of the above method, further, the length and width of the mounting bracket 3 are respectively equal to the width and thickness of the audio and video recorder body 1, the rotating shaft 4 is symmetrically distributed on both sides of the auto-focus camera 5, and the rotating shaft 4 corresponds to the first spring 8 and the push plate 9 one by one, the first clamping rod 10 is symmetrically distributed on the upper and lower sides of the push plate 9, the first clamping slot 7 is equiangularly distributed on the inner walls on both sides of the mounting bracket 3, and the telescopic sleeve 11 is symmetrically distributed on both sides of the mounting bracket 3.

[0039] like Figure 3 As shown, as a preferred embodiment, on the basis of the above-mentioned manner, further, the bottom side end of the protective cover 13 is fixedly connected to a third spring 14, and the other end of the third spring 14 is fixedly connected to a positioning block 15, and the positioning block 15 is slidably connected to the bottom side end of the protective cover 13, and a positioning groove 16 is provided at the bottom side end of the mounting frame 3. The end of the positioning block 15 is snap-fitted and connected in the positioning groove 16, and the third springs 14 are symmetrically distributed on both sides of the bottom of the protective cover 13. The third springs 14 correspond one-to-one with the positioning groove 16 through the positioning block 15, and the end cross section of the positioning block 15 The cross-sections of the positioning block 15 and the positioning groove 16 are both right-angled trapezoids. The length of the positioning block 15 is greater than the length of the positioning groove 16. The positioning block 15 and the positioning groove 16 can be used to conveniently and stably engage, fix and disassemble the protective cover 13. The engaged protective cover 13 can conveniently and stably protect the stopped audio and video recorder body 1 to prevent it from being damaged by bumps. By disassembling the protective cover 13, the protective cover 13 can be pushed away from the audio and video recorder body 1 through the telescopic sleeve 11, thereby ensuring the stability and convenience of the subsequent working state of the audio and video recorder body 1.

[0040] like Figure 5-Figure 9As shown, as a preferred embodiment, on the basis of the above method, further, the limiting groove 17 is opened in the middle part of the protective cover 13, the inner wall of the protective cover 13 is fitted with the sunshade 19, the length and width of the sunshade 19 are respectively larger than the length and width of the auto-focus camera 5, and two groups of second card slots 20 are provided, each group of second card slots 20 is provided with two, and the two groups of second card slots 20 are symmetrically distributed on the upper and lower sides of the protective cover 13, and each group of two second card slots 20 is symmetrically distributed on the left and right sides of the limiting groove 17, and the second clamping rod 23 is symmetrically distributed on both sides of the connecting plate 22. Through the provided second clamping rod 23 and the second card slot 20, the sunshade 19 can be pushed downward and unfolded, and can be conveniently engaged and fixed. At this time, the sunshade 19 can be used to prevent the auto-focus camera 5 from being directly exposed to sunlight or strong light sources, thereby reducing the influence of backlighting and making the camera picture clearer.

[0041] Specifically, when the audio and video recorder with mechanical autofocus is in use: first, when the staff needs to use the audio and video recorder, they can wear the audio and video recorder body 1 by using the fixing clip 2, and then the staff can pull the positioning block 15 outward until the positioning block 15 moves out of the positioning slot 16 on the mounting bracket 3. At this time, under the elastic action of the second spring 12 inside the telescopic sleeve 11, the telescopic sleeve 11 can be pushed to extend, and then the protective cover 13 can be pushed to automatically move upward. When the telescopic sleeve 11 is fully extended, the protective cover 13 can be pushed to move upward until it is completely separated from the autofocus camera 5, thereby ensuring the stability of the subsequent working state of the autofocus camera 5 and preventing the protective cover 13 from blocking the autofocus camera 5.

[0042] Then the staff can push the push plates 9 on both sides to move toward the middle at the same time until the first clamping rods 10 on the push plates 9 on both sides move out of the first clamping slots 7. Then the staff can push the auto-focus camera 5 on the rotating shaft 4 to rotate, and then the working angle of the auto-focus camera 5 can be conveniently adjusted according to actual needs, so that it can be conveniently aimed at the person or object to be recorded, ensuring the accuracy of the recording work; and when the angle of the auto-focus camera 5 is adjusted, the staff can release the push plates 9. At this time, under the elastic action of the first spring 8, the push plates 9 can drive the first clamping rod 10 to automatically engage with the adjacent first clamping slot 7, ensuring the stability of the engaged state of the auto-focus camera 5, and thus ensuring the stability of the subsequent recording work of the auto-focus camera 5;

[0043] During the operation of the audio and video recorder body 1, when encountering a backlight environment, the staff can pull the connecting plate 22 outward, at this time the connecting plate 22 can drive the second card rods 23 on both sides to move out of the second card slot 20 at the top, and then the staff can pull the limit block 18 to move downward in the limit slot 17. At this time, the limit block 18 can pull the shading plate 19 downward to expand until the second card rods 23 on both sides of the connecting plate 22 move to the second card slot 20 at the bottom, and then the staff can release the connecting plate 22. At this time, under the elastic action of the fourth spring 21, the second card rod 23 can be driven by the connecting plate 22 to automatically engage with the second card slot 20 at the bottom. The slot 20 can be easily and conveniently engaged and fixed with the connecting plate 22, thereby enabling the sunshade 19 to be engaged and fixed, thereby ensuring the stability of the subsequent working state of the sunshade 19. When the sunshade 19 is pushed downward and expanded, it can shield the auto-focus camera 5 from light, thereby preventing the auto-focus camera 5 from being directly exposed to sunlight or strong light sources, thereby reducing the influence of backlighting and making the camera picture clearer. Similarly, when the sunshade 19 is not needed, the same operation is only required to push the limit block 18 upward to drive the sunshade 19 to be stored and reset, and when the light is insufficient, the fill light 6 can be used to illuminate the fill light.

[0044] When the audio and video recorder body 1 finishes working, the staff only needs to press the protective cover 13 downward. At this time, the protective cover 13 can drive the positioning block 15 to move downward. During the downward movement of the positioning block 15, the inclined surface at the end of the positioning block 15 can contact the top of the mounting bracket 3. At this time, under the blocking action of the top of the mounting bracket 3, the positioning block 15 can be pushed automatically outward by the inclined surface at the end of the positioning block 15 until the protective cover 13 drives the positioning block 15 to move downward to the positioning groove 16. At this time, under the elastic action of the third spring 14, the positioning block 15 can be driven to automatically engage in the positioning groove 16, completing the convenient engagement of the protective cover 13, and then the stopped audio and video recorder body 1 can be conveniently and stably protected to prevent it from being damaged by bumps.

[0045] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements that do not deviate from the spirit and scope of the utility model are included in the scope of the claims of the present invention.
