Description

Technical Field

[0001] The utility model relates to the technical field of law enforcement recorders, and in particular to a rear-mounted camera mechanism for law enforcement recorders. Background Art

[0002] The law enforcement recorder is a piece of evidence-gathering technology that police officers carry with them when they are performing their duties. It integrates real-time video and audio recording, photography and audio recording. It can record and record the entire process of law enforcement officers in detail. The recorded content is authoritative and can be used as evidence. The law enforcement recorder can better regulate the law enforcement behavior of police officers and protect the legitimate rights and interests of police officers.

[0003] In the prior art, law enforcement recorders usually adopt an integrated design, with a camera and a display screen on the front side and a clamping part on the back side. When in use, the clamping part is clamped on the shoulder of the law enforcement officer, and the camera on the front side can record the scene in front of the law enforcement officer. However, such law enforcement recorders have the defect of not being able to record the situation behind the law enforcement officer, which is not conducive to comprehensive collection of the scene, and cannot record the scene when others cause harm to the police from behind, which is not conducive to protecting the legitimate rights and interests of the police and is not convenient for subsequent accountability.

[0004] In response to the above technical defects, the applicant intends to develop a front-to-back dual-camera law enforcement recorder that can capture the situation behind the law enforcement officer. A front camera is installed on the recorder body, and a rear camera is installed on the clamping part on the back of the recorder, so that the on-site situation can be captured more comprehensively. However, during the product design process, it was found that the clamping part of the recorder is composed of two sets of clips, which are directly clamped on the shoulder straps of the law enforcement officer's clothes when in use. This structure is not convenient for directly embedding the rear camera. Therefore, how to integrate the rear camera on the clamping part has become a technical problem that needs to be solved urgently. Utility Model Content

[0026] The utility model is further described below in conjunction with embodiments and drawings.

[0027] like Figure 1 and 2As shown, a rear camera mechanism for a law enforcement recorder includes a clamping assembly 1 and a rear camera 2 arranged at the rear end of the clamping assembly 1, wherein the clamping assembly 1 is used to clamp on the shoulder strap of the law enforcement personnel, and the front end of the clamping assembly 1 can be connected to the body A of the law enforcement recorder. Figure 2 It can be seen that when the clamping assembly 1 is clamped on the shoulder of the law enforcement officer, the rear camera 2 faces the rear of the law enforcement officer. Further, the clamping assembly 1 includes a first clamping plate 11 and a second clamping plate 12 whose ends are hinged to each other, and a first elastic element is provided between the first clamping plate 11 and the second clamping plate 12 to bring the two closer to each other. Figure 3 As shown, a slider 3 is slidably connected to the lower side of the first clamping plate 11, and the rear camera 2 is arranged at the rear end of the slider 3. A positioning component is provided on the first clamping plate 11, and the positioning component can expose the rear camera 2 to the rear end of the clamping component 1, or fold the rear camera 2 to the lower side of the first clamping plate 11.

[0028] Based on the above structural design, the clamping assembly 1 is folded and assembled on the back side of the law enforcement recorder in a rotating manner. When the law enforcement recorder is in use, the clamping assembly 1 is unfolded and can be clamped and fixed on the shoulder strap of the law enforcement officer's clothes. The slider 3 is pushed out by sliding backwards. The positioning assembly exposes the rear camera 2 at the rear end of the clamping assembly 1. The rear camera 2 can shoot and record the scene behind the law enforcement officer to ensure that there is no omission in the evidence collection at the law enforcement scene. In dangerous situations, the back is in a weak defense area. The presence of the rear camera 2 plays a deterrent role. If someone causes harm to the law enforcement officer from behind, the picture taken by the rear camera 2 can be used as evidence for subsequent accountability. After use, slide forward to retract the slider 3. The positioning assembly folds the rear camera 2 to the inner side of the first clamping plate 11, which is not only easy to carry, but also protects the rear camera 2 and extends the service life of the equipment.

[0029] Please refer to Figures 3 to 5 , a slide groove 1a extending along the length direction is provided on the lower side of the first clamping plate 11, and the slide groove 1a is recessed toward the inner side of the first clamping plate 11, and its rear end is open, and the slider 3 is slidably assembled in the slide groove 1a and can penetrate the open end of the slide groove 1a. A mounting hole 1b is provided on one side of the width direction of the slide groove 1a, and the positioning assembly includes a ball b arranged in the mounting hole 1b, and a second elastic element a supported between the end of the mounting hole 1b and the ball b. A first limiting groove 31 and a second limiting groove 32 adapted to the ball b are provided at intervals on one side of the slider 3 relative to the mounting hole 1b. By sliding the slider 3, the ball b can be positioned on the first limiting groove 31 or the second limiting groove 32 in one way. In this embodiment, the second elastic element a is a compression spring, which can apply an outward thrust to the ball b, so that the ball b can be fixedly limited in the first limiting groove 31 or the second limiting groove 32.

[0030] When the ball b is positioned on the first limiting groove 31, the rear camera 2 is exposed to the rear end of the clamping assembly 1 (refer to Figure 3 ), at this time, the rear camera 2 can be used to shoot the situation behind the law enforcement personnel; when the ball b is positioned on the second limiting groove 32, the rear camera 2 is folded and on the lower side of the first clamping plate 11 (refer to Figure 7 ) to prevent the rear camera 2 from being damaged due to long-term exposure.

[0031] Further, refer to Figure 5 The circumferential edge of the slide groove 1a protrudes downward from the lower surface of the first clamping plate 11. This design increases the thickness of the slide groove 1a and the slider 3, ensuring a stable connection between the slider 3 and the first clamping plate 11, that is, ensuring the stable installation of the rear camera 2, making the structure of the entire mechanism more stable.

[0032] like Figure 3 As shown, the rear end of the first clamping plate 11 is provided with a support portion 1c extending outwardly in an inclined manner, and the rear camera 2 is rotatably connected to the rear end of the slider 3. When the ball b is positioned on the first limiting groove 31, the rear camera 2 is exposed to the rear end of the clamping assembly 1, and the rear camera 2 can be rotated downward by gravity and supported on the support portion 1c. Considering this, refer to Figure 2 After the clamping assembly 1 is fixed on the shoulder of the law enforcement officer, the rear camera 2 can be horizontally facing the rear of the law enforcement officer, thereby ensuring the comprehensiveness and stability of the shooting.

[0033] like Figure 1 and 3 As shown, the hinge of the first clamping plate 11 is provided with two groups of first ears 1d extending downward, and the two groups of first ears 1d are symmetrically distributed along the width direction of the front part of the first clamping plate 11. Figure 6 As shown, two groups of second ears 1e extending upward are provided at the hinge of the second splint 12, the two groups of first ears 1d are hinged with the two groups of second ears 1e, and the two groups of second ears 1e are located between the two groups of first ears 1d. The first elastic element is arranged between the first ear 1d and the second ear 1e. By pressing the front end of the first splint 11, the rear ends of the first splint 11 and the second splint 12 can be moved away from each other, so as to facilitate the wearing of the law enforcement personnel.

[0034] Please refer to Figure 1 and 6 The second clamping plate 12 is provided with two groups of protrusions 1f extending upward at one end away from the first elastic element, and the upper ends of the two groups of protrusions 1f abut against the two ends of the lower side of the first clamping plate 11. Such a design can prevent the clamping assembly 1 from falling off when worn.

[0035] Re-attend Figure 2 and 6An annular hinge portion 121 is provided at one end of the second clamping plate 12 away from the rear camera 2. The annular hinge portion 121 is used to be rotatably connected to the law enforcement recorder body A, so as to facilitate the folding of the clamping assembly 1 to the rear side of the law enforcement recorder body A, thereby facilitating storage and carrying.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make a variety of similar expressions without violating the purpose and claims of the present invention, and such changes fall within the scope of protection of the present invention.
