Description

Technical Field

[0001] This invention relates to the field of law enforcement recorder technology, and in particular to a stable head-mounted law enforcement recorder. Background Technology

[0002] A law enforcement recorder is a small, portable electronic device worn on the shoulder, chest, head, or glasses of law enforcement officers. The core function of a law enforcement recorder is to record audio and video information of the law enforcement process in real time and objectively.

[0003] Currently, head-mounted law enforcement recorders mainly consist of a support structure worn on the head and the recorder itself mounted on the support structure, connected by a mounting mechanism. The support structure is typically positioned above the user's head. This placement prevents the user from observing the recorder's recording angle and position in real time, affecting recording quality. Furthermore, positioning the recorder above the user's head results in poor stability during walking and running, causing significant swaying with the user's head and leading to blurry and inaccurate footage. In addition, a significant height difference between the user's eye level and the recorder's shooting height results in inaccurate recording range. Therefore, this invention provides a stable head-mounted law enforcement recorder to meet these requirements. Summary of the Invention

[0004] The technical problem this invention aims to solve is to provide a stable head-mounted law enforcement recorder. By setting up a mounting mechanism, the traditional wearing method of head-mounted law enforcement recorders is changed. The user's neck and head can both provide support and limit the device, improving its stability and preventing large-scale shaking of the recorder during use. When the recorder is installed between the base and the top mount, the distance between the recorder and the user's line of sight is closer, thereby improving the recording effect. Moreover, the user can observe the status of the recorder in real time during use, facilitating timely adjustments and improving the ease of use. Through the above settings, the problems of poor stability and unsatisfactory recording effect in the current use of head-mounted law enforcement recorders can be solved.

[0010] Optionally, the second positioning plate is provided with a second adjustment groove, and the second head positioning mechanism includes a fixing screw inserted into the second adjustment groove. The fixing screw is adapted to the size of the second adjustment groove. One end of the fixing screw is fixedly connected to a second ball seat, and a second damping ball is rotatably connected inside the second ball seat. A second fitting plate is fixedly connected to the second damping ball. The other end of the fixing screw is screwed to a second adjustment knob. The outer wall of the second positioning plate is provided with a scale, and the scale is set on the upper and lower sides of the second adjustment groove.

[0011] Optionally, both the first and second bonding plates have a disc-shaped profile, and the center of both the first and second bonding plates has an inwardly concave arc-shaped profile.

[0012] Optionally, the third positioning plate is provided with a third adjustment groove, and a third adjustment knob is slidably connected to the third adjustment groove. The first connecting rod and the third positioning plate are connected together by the third adjustment groove and the third adjustment knob. A fourth adjustment knob is installed at the connection position of the first connecting rod and the second connecting rod, and the first connecting rod and the second connecting rod are connected together by the fourth adjustment knob.

[0013] Optionally, a fifth adjustment knob is installed at one end of the bottom support rod near the connecting plate, and the bottom support rod and the connecting plate are connected together by the fifth adjustment knob.

Those skilled in the art can adjust or modify these devices and environments according to specific needs. Detailed Implementation

[0038] The present invention provides a stable head-mounted law enforcement recorder in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0039] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0040] Generally, terms can be understood at least partly from their use in context. For example, depending at least partly on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in a singular sense, or a combination of features, structures, or characteristics in a plural sense. Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.

[0041] It is understood that the meanings of “on”, “above”, and “above” in this invention should be interpreted in the broadest manner, such that “on” means not only “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” means not only “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.

[0042] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings.

[0043] like Figures 1 to 12 As shown, an embodiment of the present invention provides a stable head-mounted law enforcement recorder, including a neck support 1 and a law enforcement recorder body 37. Connecting plates 2 are symmetrically mounted at both ends of the neck support 1, and the neck support 1 and connecting plates 2 are integrally formed. Figure 8 As shown, a rotating plate 3 is fixedly connected to the side of the connecting plate 2 away from the neck support plate 1. An adjusting seat 4 is rotatably connected to the outer wall of the rotating plate 3. The adjusting seat 4 has a relief groove 5 that matches the contour of the rotating plate 3. A rotating shaft 6 is fixedly connected inside the relief groove 5. The rotating plate 3 and the adjusting seat 4 are rotatably connected together through the rotating shaft 6. Figure 9 As shown, a positioning seat 8 is slidably connected to the side of the adjusting seat 4 away from the rotating plate 3. A first adjusting groove 7 is provided on the adjusting seat 4, and a first adjusting rod 9, whose size is adapted to the first adjusting groove 7, is fixedly connected to the positioning seat 8. The adjusting seat 4 and the positioning seat 8 are slidably connected together by the first adjusting groove 7 and the first adjusting rod 9. Figure 10As shown, a first adjustment knob 32 is screwed onto the outer wall of the first adjustment rod 9, and a scale is provided on the outer wall of the adjustment seat 4, with the scale located on the upper and lower sides of the first adjustment groove 7.

[0044] The above-described structure allows the connecting plate 2 and the adjusting seat 4 to rotate relative to each other. Because the adjusting seat 4 has a clearance groove 5, which can enclose and limit the rotating plate 3, the adjusting seat 4 can only rotate towards the inside of the connecting plate 2. This hidden rotating structure between the connecting plate 2 and the adjusting seat 4 makes the device more aesthetically pleasing and the overall structure more compact. The adjusting seat 4 and the positioning seat 8 are slid together by the first adjusting groove 7 and the first adjusting rod 9. The user can press and fix the positioning seat 8 by turning the first adjusting knob 32. Because the adjusting seat 4 has a scale, the user can refer to the scale when adjusting the relative position between the adjusting seat 4 and the positioning seat 8, thus making the length adjustment more precise. This design makes the device structure more flexible and adaptable to users with different head circumferences.

[0045] As one implementation method in this embodiment, such as Figures 1 to 12 As shown, the main body mounting mechanism is used to mount and fix the law enforcement recorder body 37, and the main body mounting mechanism is connected to the connecting plate 2 and the positioning seat 8 respectively. Figure 3 As shown, the main body mounting mechanism includes a first positioning plate 10, a second positioning plate 11, and a third positioning plate 13, which are sequentially mounted on the positioning seat 8 from top to bottom. The positioning seat 8, the first positioning plate 10, the second positioning plate 11, and the third positioning plate 13 are integrally formed. A first head positioning mechanism 15 is mounted on the first positioning plate 10, a second head positioning mechanism 21 is mounted on the second positioning plate 11, and a first connecting rod 26 is rotatably connected to the end of the third positioning plate 13 away from the positioning seat 8. A second connecting rod 27 is rotatably connected to the end of the first connecting rod 26 away from the third positioning plate 13. Figures 10-12 As shown, a third adjustment groove 14 is provided on the third positioning plate 13, and a third adjustment knob 34 is slidably connected to the third adjustment groove 14. The first connecting rod 26 and the third positioning plate 13 are connected together by the third adjustment groove 14 and the third adjustment knob 34. Specifically, a threaded rod is provided on one end of the first connecting rod 26, which is inserted into the third adjustment groove 14, and the third adjustment knob 34 is threadedly connected to the threaded rod. A fourth adjustment knob 35 is installed at the connection position of the first connecting rod 26 and the second connecting rod 27, and the first connecting rod 26 and the second connecting rod 27 are connected together by the fourth adjustment knob 35. Specifically, a threaded rod is provided on the other end of the first connecting rod 26, which is inserted into the second connecting rod 27, and the exposed end of the threaded rod is threadedly connected to the fourth adjustment knob 35.

[0046] In the above structure, the first connecting rod 26 and the third positioning plate 13 are connected together by a third adjusting knob 34. The third adjusting knob 34 can slide in the third adjusting groove 14 to adjust the relative position between the first connecting rod 26 and the third positioning plate 13. The first connecting rod 26 can also rotate on the third adjusting knob 34. The user can fix the first connecting rod 26 by turning the third adjusting knob 34. Similarly, the user can adjust and fix the relative position between the first connecting rod 26 and the second connecting rod 27 by turning the fourth adjusting knob 35.

[0047] In this embodiment, as Figure 7 As shown, the main body mounting mechanism also includes a bottom support rod 28 rotatably connected to the bottom of the connecting plate 2. A fifth adjustment knob 36 is installed at one end of the bottom support rod 28 near the connecting plate 2, and the bottom support rod 28 and the connecting plate 2 are connected together by the fifth adjustment knob 36. Specifically, a threaded rod is provided on the connecting plate 2, the threaded rod is inserted into the bottom support rod 28, and the exposed end of the threaded rod is threadedly connected to the fifth adjustment knob 36. Figure 15 and Figure 16 As shown, the end of the bottom support rod 28 is rotatably connected to the base 29, and the end of the second connecting rod 27 is rotatably connected to the top seat 30. The base 29 and the top seat 30 have the same outline. The top and bottom of the law enforcement recorder body 37 are respectively limited and locked into the top seat 30 and the base 29. The outer walls on both sides of the base 29 and the top seat 30 are fixedly connected to the third ball seat 31. The bottom support rod 28 and the base 29, as well as the second connecting rod 27 and the top seat 30, are all limited and connected together by the third ball seat 31.

[0048] Users can adjust and fix the relative position between the bottom support rod 28 and the connecting plate 2 by turning the fifth adjustment knob 36. Since the top seat 30 and the base 29 are respectively installed at the ends of the second connecting rod 27 and the bottom support rod 28, the top seat 30 and the base 29 can respectively wrap and limit the top and bottom of the law enforcement recorder body 37. Therefore, the law enforcement recorder body 37 can be fixed by means of the base 29 and the top seat 30. Since the second connecting rod 27 and the bottom support rod 28 can be rotated and adjusted, the height of the law enforcement recorder body 37 can be adjusted when the user rotates the second connecting rod 27 and the bottom support rod 28 at the same time. When the user rotates the second connecting rod 27 or the bottom support rod 28 alone, the relative distance between the base 29 and the top seat 30 can be changed, thereby achieving the effect of assembling and disassembling the law enforcement recorder body 37.

[0049] In summary, this technical solution not only allows for quick assembly and disassembly of the law enforcement recorder body 37 by setting up a mounting mechanism, but also allows the user to adjust the height of the law enforcement recorder body 37 appropriately, thereby increasing the recording range of the law enforcement recorder body 37. Furthermore, this device has multiple usage states. When the user installs the law enforcement recorder body 37 between the base 29 and the top seat 30, the height of the law enforcement recorder body 37 can be changed by synchronously rotating the bottom support rod 28 and the second connecting rod 27. State 1: The bottom support rod 28 is tilted towards the bottom of the neck support plate 1. At this time, the law enforcement recorder body 37 is located below the neck support plate 1 (e.g., Figure 1 and Figure 2 (As shown); State 2: The bottom support rod 28 is parallel to the neck support plate 1, and at this time the law enforcement recorder body 37 is located directly in front of the neck support plate 1 (as shown). Figure 3 and Figure 4 (As shown); State 3: When the device is not worn by the user, the user can rotate the adjusting seat 4 inward towards the connecting plate 2 to fold the device (as shown). Figure 5 and Figure 6 As shown, when the device is folded up, it not only takes up less space but is also easier for users to carry, thus improving the portability of the device.

[0050] In this embodiment, as Figures 10 to 14 As shown, the first head positioning mechanism 15 includes a mounting plate 16 fixed to the end of the first positioning plate 10. The end of the mounting plate 16 away from the first positioning plate 10 is threadedly connected to a first ball seat 17 by a fixing bolt 20. A first damping ball 18 is rotatably connected inside the first ball seat 17, and a first bonding plate 19 is fixedly connected to the first damping ball 18. A second adjustment groove 12 is provided on the second positioning plate 11. The second head positioning mechanism 21 includes a fixed screw 23, which is adapted to the size of the second adjustment groove 12. One end of the fixed screw 23 is threadedly connected to a second ball seat 22, and a second damping ball 24 is rotatably connected inside the second ball seat 22. A second bonding plate 25 is fixedly connected to the second damping ball 24. The other end of the fixed screw 23 is threadedly connected to a second adjustment knob 33. The fixed screw 23 is located in the second adjustment groove 12. The second ball seat 22 and the second adjustment knob 33 cooperate to clamp or loosen the second positioning plate 11. The outer wall of the second positioning plate 11 is provided with a scale, and the scale is located on the upper and lower sides of the second adjustment groove 12. The first bonding plate 19 and the second bonding plate 25 are both disc-shaped contours, and the center of the first bonding plate 19 and the second bonding plate 25 are both inwardly concave arc-shaped contours.

[0051] Compared with existing technologies, this device changes the traditional way of wearing a head-mounted law enforcement recorder. By incorporating a neck support 1, connecting plate 2, adjustment seat 4, and positioning seat 8, the user places the device from top to bottom around the neck. After placement, the neck support 1 is positioned behind the user's neck. The user's head automatically lifts the adjustment seat 4, causing it to open outwards towards the connecting plate 2 and applying an inward clamping force to the user's head. The first head positioning mechanism 15 and the second head positioning mechanism 21 fit snugly against both sides of the user's head. With the support of the neck and head, the device is securely fixed during law enforcement recording. After the main body 37 is installed between the base 29 and the top seat 30, the law enforcement recorder 37 is located in front of the user's neck and face. The user can change the height of the law enforcement recorder 37 by rotating and adjusting the bottom support 28 and the second connecting rod 27 to make the law enforcement recorder 37 at a suitable height for recording. This setting makes the law enforcement recorder 37 closer to the user's line of sight, thereby improving the recording effect. Moreover, the user can observe the usage status of the law enforcement recorder 37 in real time during use, which facilitates timely adjustments and improves the ease of use of the law enforcement recorder 37.

[0052] By setting a first head positioning mechanism 15 and a second head positioning mechanism 21 in the main body mounting mechanism, the stability of the device when worn by the user can be further improved. Specifically, when the user wears the device, the first fitting plate 19 and the second fitting plate 25 on the first head positioning mechanism 15 and the second head positioning mechanism 21 will fit against the surface of the user's head. At this time, the support force of the user's neck on the neck support plate 1 and the support force of the head on the first head positioning mechanism 15 and the second head positioning mechanism 21 can improve the stability of the device and prevent the law enforcement recorder body 37 from shaking significantly during use. In addition, the positions of the adjustment seat 4, the positioning seat 8, the first head positioning mechanism 15 and the second head positioning mechanism 21 in the main body mounting mechanism can be adjusted to suit different users and improve the adaptability of the device.

[0053] The working principle of the technical solution provided by this invention is as follows:

[0054] In use, the user puts the device on from the top of their head to their neck. After placement, the neck support 1 is located behind the user's neck. The user's head will automatically lift the adjustment seat 4, causing the adjustment seat 4 to open outward toward the connecting plate 2 and apply an inward clamping force to the user's head. The first head positioning mechanism 15 and the second head positioning mechanism 21 fit against the sides of the user's head. At this time, with the support of the neck and head, the device can be fixed. During the wearing process, the user can adjust the relative position between the adjustment seat 4 and the positioning seat 8 by turning the first adjustment knob 32, adjust the relative position between the second head positioning mechanism 21 and the second positioning plate 11 by turning the second adjustment knob 33, and change the relative position between the first head positioning mechanism 15 and the first positioning plate 10 by pulling the mounting plate 16, thereby ensuring that the device can be firmly and stably worn on the user's body.

[0055] During use, the user can adjust and fix the angle of the bottom support rod 28 by turning the fifth adjustment knob 36, and adjust and fix the angle of the first connecting rod 26 and the second connecting rod 27 by turning the third adjustment knob 34 and the fourth adjustment knob 35. When the user adjusts the angle of the second connecting rod 27 and the bottom support rod 28 simultaneously, the height of the law enforcement recorder body 37 can be adjusted. When the user rotates the second connecting rod 27 or the bottom support rod 28 separately, the relative distance between the base 29 and the top seat 30 can be changed, thereby achieving the effect of assembling and disassembling the law enforcement recorder body 37. In addition, this device has multiple usage states. When the user puts the law enforcement recorder body into position... When the device is installed between the base 29 and the top seat 30, the height of the law enforcement recorder body 37 can be changed by synchronously rotating the bottom support rod 28 and the second connecting rod 27. State 1: The bottom support rod 28 is tilted towards the bottom of the neck support plate 1, and the law enforcement recorder body 37 is located below the neck support plate 1. State 2: The bottom support rod 28 is parallel to the neck support plate 1, and the law enforcement recorder body 37 is located directly in front of the neck support plate 1. State 3: When the device is not worn by the user, the user can rotate the adjustment seat 4 inward to the connecting plate 2 to fold the device. When the device is folded up, it not only takes up less space, but also makes it easier for the user to carry, thus improving the portability of the device.
