Description

Technical Field

[0001] This utility model relates to the field of law enforcement recorders, and in particular to an outdoor drop-resistant law enforcement recorder. Background Technology

[0002] Body-worn cameras are indispensable equipment for law enforcement officers during outdoor operations. They record the actual situation at the scene of law enforcement, providing crucial evidence for law enforcement activities. The recorded audio and video data plays an important role in subsequent case handling and dispute resolution.

[0003] In current technology, law enforcement officers working outdoors carry body cameras. They typically wear the cameras on their bodies, such as on their chest or shoulders, or hold them in their hands, so that they can start recording at any time.

[0004] However, if law enforcement officers accidentally fall while enforcing the law in mountainous areas, the impact force cannot be effectively dispersed when they fall. They can only rely on the hardness of the outer shell to resist the impact. This means that when they fall, the impact force acts directly on the law enforcement recorder, which can easily cause internal components to loosen or be damaged, affecting the normal operation of the equipment. Therefore, an outdoor drop-resistant law enforcement recorder is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an outdoor drop-resistant law enforcement recorder, which aims to solve the problem of insufficient protection in the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an outdoor drop-resistant law enforcement recorder, comprising a law enforcement recorder, a protective box externally disposed on the law enforcement recorder, a protective mechanism internally disposed on the protective box, the protective mechanism comprising a ball groove, the bottom outer wall of the ball groove being fixedly connected to the inner wall of the bottom of the protective box, a ball being slidably connected inside the ball groove, a damper being fixedly connected to the inner wall of the protective box, a fixing plate being fixedly connected to the end of the damper away from the inner wall of the protective box, a first spring being fixedly connected to the outer wall of the fixing plate, the end of the first spring away from the fixing plate being fixedly connected to the inner wall of the protective box, and the outer wall of the fixing plate contacting the outer wall of the law enforcement recorder.

[0007] As a further description of the above technical solution: a glass window is fixedly connected to the inner wall of the protective box.

[0008] As a further description of the above technical solution: a shape memory alloy is embedded in the inner wall of the ball groove, and the outer wall of the shape memory alloy is in contact with the outer wall of the ball.

[0009] As a further description of the above technical solution: a rubber pad is fixedly connected to the inner wall of the back of the protective box.

[0010] As a further description of the above technical solution: a placement groove is fixedly connected to the inner wall of the front of the protective box, a second spring is fixedly connected to the inner wall at the bottom of the placement groove, and a baffle plate is fixedly connected to the top of the second spring.

[0011] As a further description of the above technical solution: a telescopic rod is fixedly connected to the inner wall of the bottom of the placement slot, the top end of the telescopic rod is fixedly connected to the bottom of the baffle, and the outer wall of the baffle is slidably connected to the inner wall of the protective box.

[0012] As a further description of the above technical solution: the top of the protective box is hinged to a top cover, and a handle is fixedly connected to the outer wall of the top cover.

[0013] As a further description of the above technical solution: a connecting plate is fixedly connected to the outer wall of the handle, and a limiting rod is fixedly connected to the bottom of the connecting plate. The bottom end of the limiting rod is inserted into a through groove opened on the plug rod.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, when subjected to a falling impact, the ball rolls in the ball groove, changing the direction of the impact force and dispersing some of the energy. After the shape memory alloy generates heat during the impact and reaches the phase transition temperature, it locally hardens the ball groove, more effectively constraining the movement of the ball and further dispersing the impact force. The first spring stores energy during the impact, and after the impact disappears, it pushes the law enforcement recorder back to a relatively stable position with the cooperation of the damper, reducing the impact on it.

[0016] 2. In this utility model, when subjected to a strong drop impact, the limiting rod disengages from the through groove of the insert rod, the insert rod no longer restricts the shield, the second spring releases its stored energy, and drives the shield to slide down along the telescopic rod, thus protecting the lens in time. This not only does not affect the convenience of normal shooting operation of the law enforcement recorder, but also provides protection for the lens and extends the lens's service life.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1 - Figure 3 This utility model provides an embodiment of an outdoor drop-resistant law enforcement recorder, including a law enforcement recorder 1. A protective case 2 is provided on the outside of the law enforcement recorder 1. The protective case 2 serves to protect the law enforcement recorder 1, effectively preventing it from being directly impacted or dropped in complex outdoor environments. The protective case 2 has an internal protective mechanism, including a ball groove 9. The bottom outer wall of the ball groove 9 is fixedly connected to the inner wall of the bottom of the protective case 2. A ball 10 is slidably connected inside the ball groove 9, providing a track for the ball 10. When dropped, the ball 10 can roll within the ball groove 9. The rolling of the ball 10 disperses some of the impact force and changes its direction, thereby reducing the direct impact on the law enforcement recorder 1 and enhancing the drop resistance of the entire device. Regardless of the direction of the impact, it provides a certain buffering effect, improving the all-round protection.

[0025] Reference Figure 1 - Figure 3A damper 5 is fixedly connected to the inner wall of the protective box 2. A fixing plate 7 is fixedly connected to the end of the damper 5 away from the inner wall of the protective box 2. A first spring 6 is fixedly connected to the outer wall of the fixing plate 7. The end of the first spring 6 away from the fixing plate 7 is fixedly connected to the inner wall of the protective box 2. The outer wall of the fixing plate 7 contacts the outer wall of the law enforcement recorder 1. The first spring 6 is elastic and will undergo elastic deformation when impacted, storing energy. When the impact force disappears, the first spring 6 will return to its original shape, releasing the stored energy and pushing the law enforcement recorder 1 back to a relatively stable position. Under the restriction of the damper 5, simple harmonic motion is avoided, enhancing the buffering and reset ability of the law enforcement recorder 1 and reducing the impact on the law enforcement recorder 1. A glass window 4 is fixedly connected to the inner wall of the protective box 2. While protecting the law enforcement recorder 1, its recording function is not affected. A shape memory alloy 11 is embedded in the inner wall of the ball groove 9. The outer wall of the shape memory alloy 11 contacts the outer wall of the ball 10. The shape memory alloy wire 11 is in a soft state at room temperature. At this time, the ball groove 9 can flexibly restrain the ball 10. When the protective box 2 is dropped, the mechanical energy generated by the impact causes the ball 10 to roll at high speed. It rubs against the outer wall of the shape memory alloy 11 and generates heat. When the temperature reaches the phase transition temperature of the shape memory alloy 11, the alloy wire quickly returns to the pre-set high-rigidity shape, making the outer wall harder and able to withstand greater impact force, preventing the ball groove 9 from deforming. At the same time, it restrains the movement of the ball 10 more effectively, dispersing the impact force more effectively and enhancing the protection of the law enforcement recorder 1.

[0026] Reference Figure 2 - Figure 4 A rubber pad 8 is fixedly connected to the inner wall of the back of the protective box 2. The rubber pad 8 has good elasticity and cushioning performance. A placement groove 12 is fixedly connected to the inner wall of the front of the protective box 2. A second spring 13 is fixedly connected to the inner wall of the bottom of the placement groove 12. Under normal conditions, the second spring 13 is in a tensile state. A baffle plate 14 is fixedly connected to the top of the second spring 13. A telescopic rod is fixedly connected to the inner wall of the bottom of the placement groove 12. The telescopic rod has a limiting effect on the second spring 13 to prevent the second spring 13 from twisting. The top of the telescopic rod is fixedly connected to the bottom of the baffle plate 14. The outer wall of the baffle plate 14 is slidably connected to the inner wall of the protective box 2.

[0027] Reference Figure 1 - Figure 3The top of the protective box 2 is hinged to a top cover 3. A handle 16 is fixedly connected to the outer wall of the top cover 3. A connecting plate 17 is fixedly connected to the outer wall of the handle 16. A limit rod 18 is fixedly connected to the bottom of the connecting plate 17. The bottom end of the limit rod 18 is inserted into a through groove on the insert rod 15 to restrict the position of the insert rod 15. If it is impacted, the limit rod 18 will disengage from the through groove, thereby causing the insert rod 15 to disengage from its original position, so that the shield 14 is no longer restricted. Under the release of the energy stored in the second spring 13, the shield 14 will move downward to protect the lens of the law enforcement recorder 1.

[0028] Working principle: Law enforcement officers hold handle 16, which drives the top cover 3 to rotate around the hinge point, opening the top cover 3 of the protective box 2. Then, by pulling the shield 14 upward, the insert rod 15 is inserted to limit the shield 14. The top cover 3 is then closed, allowing the limiting rod 18 to be inserted into the through groove of the insert rod 15. At this time, the second spring 13 is in a stretched state, the shield 14 is kept in a high position, and the lens of the law enforcement recorder 1 is exposed, allowing normal law enforcement recording work. This ensures that the law enforcement recorder 1 can also record normally when it is inside the protective box 2.

[0029] When subjected to a falling impact, the ball 10 begins to roll within the ball groove 9. The ball groove 9 provides a track for the ball 10. The rolling of the ball 10 disperses some of the impact force, changes its direction, and reduces the direct impact on the law enforcement recorder 1. The ball 10 generates heat through friction with the shape memory alloy 11 on the inner wall of the ball groove 9. When the temperature reaches the phase transformation temperature of the shape memory alloy 11, the alloy returns to the preset high-rigidity shape, and the ball groove 9 locally hardens, more effectively restraining the movement of the ball 10 and further dispersing the impact force.

[0030] The damper 5 and the first spring 6 function to suppress the vibration of the law enforcement recorder 1 and reduce the amplitude and speed of the swaying. The first spring 6 undergoes elastic deformation to store energy during impact and returns to its original shape after the impact disappears, pushing the law enforcement recorder 1 back to a relatively stable position. The two work together to reduce the impact on the law enforcement recorder 1. When the protective box 2 is dropped, the rubber pad 8 on the back absorbs the impact force on the back of the device using its good elasticity and cushioning performance, protecting the back components of the law enforcement recorder 1.

[0031] If the impact intensity is large, causing the limiting rod 18 to disengage from the through slot on the insert rod 15, the position of the insert rod 15 changes, and it no longer restricts the cover plate 14. At this time, the second spring 13, which is in a stretched state, releases its stored energy, causing the cover plate 14 to move downward along the telescopic rod. The telescopic rod not only limits the second spring 13 to prevent it from twisting, but also provides guidance for the movement of the cover plate 14, ensuring that the cover plate 14 slides down stably and provides timely protection for the lens of the law enforcement recorder 1 to prevent damage to the lens.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
