[0001] This utility model relates to the field of electronic product technology, and in particular to a law enforcement device. Background Technology

[0002] Law enforcement equipment is a specialized device used for judicial interrogation, widely applied in public security organs, procuratorates, discipline inspection commissions, and other departments. It typically integrates functions such as high-definition audio and video recording, simultaneous recording, remote interrogation, evidence collection, and record management, ensuring the authenticity and impartiality of the interrogation process.

[0003] In existing law enforcement equipment, touch mechanisms are typically incorporated. As a crucial input device, the touch mechanism provides an intuitive interactive experience, replacing the traditional mouse for cursor control, gesture operations, and other functions. Currently, law enforcement equipment generally has a support structure within its body. During touch mechanism installation, the touch circuit board and cover plate must be manually installed sequentially into designated positions on the support structure to ensure proper operation.

[0004] However, this setup necessitates adjusting the touch circuit board's position during installation onto the bracket structure to ensure accurate alignment. This adds extra time for alignment, reducing installation efficiency. Furthermore, any looseness between the touch circuit board and the bracket structure could affect the stability of the touch circuit board's connection, rendering the law enforcement equipment unusable.

[0012] In one embodiment, the touch mechanism further includes a mounting bracket disposed within the accommodating cavity and corresponding to the mounting opening. One side of the mounting bracket engages with the inner wall of the accommodating cavity to clamp and fix the first end.

[0013] In one embodiment, the body is further provided with a support baffle located in the mounting port, the touch circuit board is provided with a micro switch corresponding to the support baffle, and the second end of the bracket plate is provided with a clearance hole to avoid the micro switch;

[0014] Pressing the cover plate causes the micro switch on the touch circuit board to come into contact with the support baffle, thereby changing the state of the micro switch.

[0036] Law enforcement equipment is a specialized device used for judicial interrogation, widely applied in public security organs, procuratorates, discipline inspection commissions, and other departments. It typically integrates functions such as high-definition audio and video recording, simultaneous recording, remote interrogation, evidence collection, and record management, ensuring the authenticity and impartiality of the interrogation process.

[0037] In existing law enforcement equipment, touch mechanisms are typically incorporated. As a crucial input device, the touch mechanism provides an intuitive interactive experience, replacing the traditional mouse for cursor control, gesture operations, and other functions. Currently, law enforcement equipment generally has a support structure within its body. During touch mechanism installation, the touch circuit board and cover plate must be manually installed sequentially into designated positions on the support structure to ensure proper operation.

[0038] However, this setup necessitates adjusting the touch circuit board's position during installation onto the bracket structure to ensure accurate alignment. This adds extra time for alignment, reducing installation efficiency. Furthermore, any looseness between the touch circuit board and the bracket structure could affect the stability of the touch circuit board's connection, rendering the law enforcement equipment unusable.

[0039] The main purpose of this utility model is to provide a law enforcement device 100, which aims to improve installation efficiency and ensure that the touch circuit board 22 and the bracket plate 23 can be quickly positioned and aligned.

[0040] Please see Figures 1 to 8 In one embodiment of this utility model, the law enforcement device 100 includes a body 1 and a touch mechanism 2. The body 1 has a receiving cavity 11 and an installation port 12 communicating with the receiving cavity 11. The touch mechanism 2 includes a cover plate 21, a touch circuit board 22, and a support plate 23. The support plate 23 has a first end 231 and a second end 232 disposed opposite to each other. The first end 231 is installed on the inner wall of the receiving cavity 11, and the second end 232 extends into the installation port 12. The support plate 23 is provided with a first alignment structure 233. The touch circuit board 22 is connected to the side of the support plate 23 facing away from the receiving cavity 11, and the touch circuit board 22 is provided with a second alignment structure 221 corresponding to the first alignment structure 233. The cover plate 21 is connected to the side of the touch circuit board 22 facing away from the support plate 23. The support plate 23 and the touch circuit board 22 are positioned by the first alignment structure 233 and the second alignment structure 221 to be connected and installed at the installation port 12.

[0041] The technical solution of this utility model involves setting a first alignment structure 233 on the bracket plate 23 and a corresponding second alignment structure 221 on the touch circuit board 22. During installation, the touch circuit board 22 and the bracket plate 23 are pre-assembled together using the first alignment structure 233 and the second alignment structure 221, ensuring quick positioning and alignment without additional adjustments, thus accelerating installation efficiency. Then, the touch circuit board 22 is installed onto the body 1, ensuring that it does not easily wobble between itself and the bracket plate 23 after installation. Finally, a cover plate 21 is installed on the surface of the touch circuit board 22 to further enhance the stability of the overall structure.

[0042] Understandably, the mounting opening 12 is an opening area extending outward from the accommodating cavity 11. The size of the mounting opening 12 is adapted to the projected area of ​​the touch circuit board 22. Optionally, the edge of the mounting opening 12 can be chamfered to assist in the insertion of the cover plate 21. The bracket plate 23 is used to support the touch circuit board 22. The first end 231 of the bracket plate 23 can be fixed to the inner wall of the accommodating cavity 11 by bolts or clips. At the same time, the second end 232 extends into the mounting opening 12 to provide a mounting surface for the touch circuit board 22. Furthermore, the edge of the mounting opening 12 and the edge of the second end 232 of the bracket plate 23 form a limiting fit.

[0043] The first alignment structure 233 and the second alignment structure 221 cooperate with each other to complete the positioning and alignment of the touch circuit board 22 and the support plate 23. Specifically, the first alignment structure 233 can adopt a boss, groove or through hole structure, for example, a positioning hole is formed by punching on the surface of the support plate 23. The second alignment structure 221 is a positioning post corresponding to the positioning hole. The height of the positioning post is slightly higher than the depth of the positioning hole so as to form an interference fit with the positioning hole.

[0044] In one implementation, please refer to Figure 7 and Figure 8 The first alignment structure 233 is a first alignment hole provided on the bracket plate 23, and the second alignment structure 221 is a second alignment hole provided on the touch circuit board 22. The first alignment hole and the second alignment hole have the same shape.

[0045] In this embodiment, both the first alignment structure 233 and the second alignment structure 221 are through-hole structures. During pre-assembly, the positioning pins of the fixture are simultaneously inserted into the first alignment hole of the support plate 23 and the second alignment hole of the touch circuit board 22, allowing the touch circuit board 22 and the support plate 23 to quickly align. Then, the touch circuit board 22 and the support plate 23 are bonded together and removed from the fixture, thus completing the pre-assembly operation. The shapes of the first alignment hole and the second alignment hole can be triangular, rectangular, circular, or other shapes, and are not limited here.

[0046] Understandably, the positioning pins of the fixture are generally cylindrical structures. When the first alignment hole and the second alignment hole have the same shape, the positioning pins are inserted into the first alignment hole and the second alignment hole to ensure that the bracket plate 23 and the touch circuit board 22 are aligned.

[0047] In one implementation, please refer to Figure 7 and Figure 8 Multiple first alignment holes are provided, and multiple first alignment holes are symmetrically arranged inside the bracket plate 23. The touch circuit board 22 is provided with a second alignment hole corresponding to each first alignment hole.

[0048] In this embodiment, the support plate 23 has a plurality of first alignment holes symmetrically arranged inside, and the touch circuit board 22 has the same number of second alignment holes at the corresponding positions that contact the support plate 23. When the fixture passes through the first alignment holes and the second alignment holes, multiple independent positioning points are formed between the touch circuit board 22 and the support plate 23. It can be understood that since the first alignment holes are symmetrically distributed inside the support plate 23, force balance can be ensured, avoiding offset caused by unilateral positioning.

[0049] In one implementation, please refer to Figure 3 and Figure 7 The touch mechanism 2 also includes a mounting bracket 24, which is located in the accommodating cavity 11 and corresponds to the mounting port 12. One side of the mounting bracket 24 cooperates with the inner wall of the accommodating cavity 11 to clamp and fix the first end 231.

[0050] In this embodiment, the mounting bracket 24 is disposed on the inner wall of the accommodating cavity 11 and adjacent to the mounting port 12. When fixing the first end 231 of the bracket plate 23, one end of the mounting bracket 24 abuts against the first end 231 of the bracket plate 23. At this time, a fixing structure such as a bolt or screw passes through the mounting bracket 24 and the bracket plate 23 in sequence and is inserted into the inner wall of the accommodating cavity 11, fastening the mounting bracket 24 to the inner wall of the accommodating cavity 11. Furthermore, the first end 231 of the bracket plate 23 is clamped between the mounting bracket 24 and the inner wall of the accommodating cavity 11 to restrict the movement of the bracket plate 23 and ensure the stability of the bracket plate 23.

[0051] It is understandable that a snap-fit ​​structure can also be provided on the inner wall of the accommodating cavity 11 to fix the mounting bracket 24 to the inner wall of the accommodating cavity 11.

[0052] In one implementation, please refer to Figure 3 and Figure 4The main body 1 is also provided with a support baffle 121 located in the mounting port 12. The touch circuit board 22 is provided with a micro switch 222 corresponding to the support baffle 121. The second end 232 of the bracket plate 23 is provided with a clearance hole 234 to avoid the micro switch 222. Pressing the cover plate 21 causes the micro switch 222 of the touch circuit board 22 to abut against the support baffle 121, thereby changing the state of the micro switch 222.

[0053] In this embodiment, the micro switch 222 can generate electrical signal changes through physical contact deformation. A support baffle 121 is provided in the mounting port 12 to provide a reference surface for mechanical contact of the micro switch 222. The second end 232 of the bracket plate 23 is provided with a clearance hole 234, which can provide clearance for the movement of the micro switch 222.

[0054] Understandably, when an external force is applied to the surface of the cover plate 21, the touch circuit board 22 moves relative to the support baffle 121 under pressure, at which point the trigger end of the micro switch 222 can make physical contact with the support baffle 121. When the micro switch 222 is pressed to the deformation threshold, the internal contact state of the micro switch 222 switches and outputs an electrical signal. This signal is transmitted to the control system of the law enforcement device 100 through the control circuit of the touch circuit board 22, thereby completing the corresponding operation.

[0055] In one implementation, please refer to Figure 3 and Figure 4 The support baffle 121 facing the touch circuit board 22 has an elastic pad 1211 corresponding to the micro switch 222.

[0056] In this embodiment, the elastic pad 1211 is fixed to the surface of the support baffle 121 by adhesive or snap-fit, and is used to absorb the pressing pressure when the touch circuit board 22 contacts the support baffle 121.

[0057] Optionally, the elastic gasket 1211 can be implemented using a sheet structure of silicone or rubber material, with a thickness ranging from 0.5 mm to 3 mm.

[0058] Understandably, when the cover plate 21 is pressed, the touch circuit board 22 drives the micro switch 222 to move towards the support baffle 121. At this time, the elastic pad 1211 is compressed and deformed. The elastic pad 1211 undergoes elastic deformation under pressure, converting the pressing force into internal stress, and then eliminating residual stress through elastic restoring force. In this way, the rigid contact between the micro switch 222 and the support baffle 121 is transformed into elastic contact, which not only effectively reduces the impact force during contact, but also maintains a stable contact pressure value through elastic support, avoiding poor contact due to wear.

[0059] In one implementation, please refer to Figure 5 The inner wall of the accommodating cavity 11 is provided with a limiting protrusion 111. The limiting protrusion 111 is arranged along the periphery of the support plate 23 and has a gap with the support plate 23. The limiting protrusion 111 is used to limit the support plate 23.

[0060] In this embodiment, a limiting protrusion 111 is provided on the inner wall of the accommodating cavity 11. The limiting protrusion 111 surrounds the periphery of the support plate 23 to prevent the support plate 23 from shifting in the lateral direction. At the same time, a gap is provided between the limiting protrusion 111 and the edge of the support plate 23. The gap avoids rigid contact between the support plate 23 and the limiting protrusion 111, reducing stress concentration caused by processing errors or temperature changes.

[0061] Understandably, when the bracket plate 23 is abutted and fixed by the mounting bracket 24, the limiting protrusion 111 and the mounting bracket 24 work together to limit the vertical and horizontal movement of the bracket plate 23, so as to ensure the alignment accuracy of the touch circuit board 22 and the bracket plate 23 during installation.

[0062] In one implementation, please refer to Figure 5 and Figure 7 The two sides of the mounting bracket 24 located between the first end 231 and the second end 232 abut against the limiting protrusion 111 respectively, and are fixed to the inner wall of the accommodating cavity 11 by the locking member.

[0063] In this embodiment, the mounting bracket 24 has a stepped structure. The distance between the side of the mounting bracket 24 corresponding to the first end 231 and the bracket plate 23 is a first distance, and the distance between the side of the mounting bracket 24 corresponding to the second end 232 and the bracket plate 23 is a second distance, which is greater than the first distance. This allows one side of the mounting bracket 24 to be fixedly abutted against the first end 231, while the other side of the mounting bracket 24 has a gap with the bracket plate 23, thus providing movement space for the micro switch 222. At the same time, the other two opposite sides of the mounting bracket 24 abut against the limiting protrusion 111 in the vertical direction, ensuring that the side of the mounting bracket 24 away from the first end 231 does not shift in the vertical direction, thereby ensuring the stability of the mounting bracket 24.

[0064] It is understandable that, in order to further improve the stability of the mounting bracket 24, the two sides of the mounting bracket 24 located between the first end 231 and the second end 232 can be fixed to the inner wall of the accommodating cavity 11 by locking components. The locking components can be bolts or screws, and are not limited here.

[0065] In one implementation, please refer to Figure 7 and Figure 8The bracket plate 23 is provided with a first through hole 235, and the mounting bracket 24 is provided with a second through hole 241 corresponding to the first through hole 235. The first through hole 235 and the second through hole 241 are used to avoid the electronic components of the touch circuit board 22.

[0066] In this embodiment, the bracket plate 23 and the mounting bracket 24 are respectively provided with a first through hole 235 and a second through hole 241, both of which are used to provide clearance space for the electronic components of the touch circuit board 22. The first through hole 235 and the second through hole 241 can be implemented in the form of a circle, rectangle or other geometric shapes, and their size and position can be adjusted according to the layout of the electronic components of the touch circuit board 22, which is not limited here.

[0067] In existing technologies, support assemblies typically employ a solid structure. During pressing, the pressure is directly transmitted to the entire structure of the support assembly, causing it to deform. However, the deformation of the support assembly lacks a clear guiding path and is randomly distributed across various areas. This uncontrollable deformation not only reduces the pressing response performance of the microswitch 222 but may also lead to localized damage to the support assembly, thereby affecting the stability of the structure.

[0068] To address the above problems, in one embodiment, please refer to... Figure 7 and Figure 8 The support plate 23 is provided with multiple strip holes 236, which are arranged along the same straight line and close to the first end 231.

[0069] In this embodiment, when the touch circuit board 22 is assembled with the support plate 23, an external force is applied to the second end 232 of the support plate 23, causing local bending deformation of the second end 232. Multiple strip holes 236 are distributed along a straight line near the first end 231, forming a region with weak structural strength, allowing deformation energy to be preferentially released along the extension direction of the strip holes 236. During the pressing process, the solid connection between the strip holes 236 undergoes elastic deformation, thereby limiting the deformation range from spreading to the second end 232. This allows the support plate 23 to preferentially undergo controllable elastic deformation near the first end 231 when under pressure, reducing the risk of damage to the second end 232. Simultaneously, directional deformation maintains the connection stability between the support plate 23 and the touch circuit board 22, preventing loosening due to stress concentration.

[0070] Understandably, the strip hole 236 is located near the first end 231 and in the area corresponding to the edge of the bracket plate 23 and the mounting port 12. Specifically, it can be located within a range of 5-15 mm from the edge of the first end 231 to form a deformable area.

[0071] In one implementation, please refer to Figure 1The main body 1 includes a main casing 13, a motherboard, and a display screen 14. The main casing 13 forms a receiving cavity 11, and the motherboard is located inside the receiving cavity 11. The display screen 14 is rotatably connected to one end of the main casing 13 for displaying information, and a camera 15 is provided at the end of the display screen 14 away from the main casing 13.

[0072] Optionally, two cameras 15 are provided, facing opposite directions, to record information about the interrogator and the interrogated person respectively, ensuring complete recording of the law enforcement process. Simultaneously, each camera 15 can rotate around its own axis to adjust the camera angle for easier recording.

[0073] In this embodiment, a fan is provided inside the accommodating cavity 11, and a heat dissipation port 131 communicating with the accommodating cavity 11 is also provided on the main casing 13. At least two heat dissipation ports 131 are provided to form a heat dissipation channel between the two heat dissipation ports 131. When the fan rotates, it drives the air to flow in the heat dissipation channel, thereby blowing out hot air and drawing in cold air to dissipate heat from the motherboard.

[0074] Meanwhile, the main unit casing 13 is also equipped with a transmission port 132, which is electrically connected to the motherboard. Other devices can be connected to the transmission port 132 via a data cable to achieve information exchange.

[0075] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
