Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic product technology, and in particular to a law enforcement device. Background Technology
[0002] In modern law enforcement, law enforcement equipment, as information display and recording devices, is widely used in various interrogation scenarios. Law enforcement equipment typically integrates high-definition displays, audio input / output devices, and multiple data interfaces to meet the complex needs of interrogation processes, including questioning suspects, presenting evidence, recording interrogations, and synchronous transmission. The display screen, in particular, needs to possess characteristics such as high resolution, high contrast, wide color gamut, and good viewing angles to ensure that interrogators can clearly and accurately view various information.
[0003] In existing law enforcement equipment, the display screen is mostly mounted using a mid-frame fixation method. First, the perimeter of the display screen is fixed to the mid-frame, forming a relatively independent display unit. Then, this display unit is mounted onto the rear cover, achieving a secure connection between the display unit and the rear cover. Finally, the panel is fitted onto the mounting structure of the display unit and rear cover, and sealed with sealant, screws, etc., to ensure the normal operation of the law enforcement equipment.
[0004] However, this setup makes the installation process complex and cumbersome, requiring sequential steps such as fixing the display screen to the mid-frame, connecting the display unit to the rear cover, and sealing the panel, which consumes a significant amount of time. Furthermore, repairing or replacing parts requires disassembling multiple components, which is tedious and can easily damage other parts, affecting the normal operation of the equipment and hindering rapid assembly and repair. Utility Model Content
[0005] The main purpose of this invention is to propose a law enforcement device that simplifies the structure of the display screen and improves installation and maintenance efficiency.
[0006] To achieve the above objectives, this utility model proposes a law enforcement device, which includes:
[0007] Main unit casing; and
[0008] A display assembly includes a rear cover, a display screen, and a panel. The rear cover is rotatably connected to the main housing. The rear cover includes an integrally formed bottom shell and a support portion. The support portion is located on the periphery of the bottom shell and surrounds the bottom shell to form an accommodating space. A support surface is formed on the side of the support portion facing away from the bottom shell. The display screen is located on the panel. The periphery of the panel is supported by the support surface and covers the opening of the accommodating space so that the display screen is located within the accommodating space.
[0009] In one embodiment, a first gap is formed between the periphery of the display screen and the side of the support facing the accommodating space;
[0010] And / or, a second gap is formed between the side of the display screen facing the bottom shell and the bottom shell.
[0011] In one embodiment, the periphery of the support portion is provided with a limiting protrusion protruding from the support surface, and the periphery of the panel is supported on the support surface and abuts against the limiting protrusion.
[0012] In one embodiment, the height of the limiting protrusion protruding from the support surface is the same as the thickness of the panel.
[0013] In one embodiment, the support portion is provided with a weight-reducing structure.
[0014] In one embodiment, the weight-reducing structure is a weight-reducing groove formed by a recess on the side of the support portion facing the accommodating space, with the opening of the weight-reducing groove facing the accommodating space.
[0015] Alternatively, the weight-reducing structure may be a weight-reducing inner cavity formed by the support portion, so that the support portion is a hollow structure.
[0016] In one embodiment, the support portion has two oppositely arranged short sides, and the weight reduction structure includes a plurality of such structures, which are symmetrically arranged on the two short sides.
[0017] In one embodiment, the support portion has a rotating opening on the side near the main housing, and the rear end cover also includes a support housing disposed on the bottom housing. The support housing is connected to the support portion and has a notch corresponding to the rotating opening. The support housing and the support portion enclose a rotating groove, and the rotating groove communicates with the rotating opening.
[0018] A rotating component is provided inside the rotating opening. One end of the rotating component is inserted into the rotating groove and connected to the supporting housing. The other end of the rotating component is located inside the rotating opening and is rotatably connected to the main housing.
[0019] In one embodiment, the supporting housing is further provided with a supporting structure on the side facing away from the bottom shell. The supporting structure is flush with the supporting surface, and the panel is supported on the supporting surface and the supporting structure.
[0020] In one embodiment, a wiring cavity is formed between the side of the support housing facing the bottom shell and the bottom shell, and a wiring channel is formed between the side of the support housing near the main housing and the support part. The wiring cavity communicates with the rotating port through the wiring channel and is coaxially arranged with the rotating groove.
[0021] The wiring of the display screen passes sequentially through the wiring cavity, the wiring channel, and the rotating port, and is electrically connected to the main unit housing.
[0022] The technical solution of this utility model eliminates the need for a middle frame structure by using an integrally formed bottom shell and support part. During installation, the display screen is first pre-assembled with the panel, and then the panel is placed directly on the support surface of the support part, ensuring that the panel covers the accommodating space formed by the bottom shell and the support part. This completes the installation of the display screen. This not only simplifies the installation process and improves installation efficiency, but also facilitates maintenance and replacement of parts, solving the problem of complex display screen installation structure in existing law enforcement equipment.

[0038] In modern law enforcement, law enforcement equipment, as information display and recording devices, is widely used in various interrogation scenarios. Law enforcement equipment typically integrates high-definition displays, audio input / output devices, and multiple data interfaces to meet the complex needs of interrogation processes, including questioning suspects, presenting evidence, recording interrogations, and synchronous transmission. The display screen, in particular, needs to possess characteristics such as high resolution, high contrast, wide color gamut, and good viewing angles to ensure that interrogators can clearly and accurately view various information.
[0039] In existing law enforcement equipment, the display screen is mostly mounted using a mid-frame fixation method. First, the perimeter of the display screen is fixed to the mid-frame, forming a relatively independent display unit. Then, this display unit is mounted onto the rear cover, achieving a secure connection between the display unit and the rear cover. Finally, the panel is fitted onto the mounting structure of the display unit and rear cover, and sealed with sealant, screws, etc., to ensure the normal operation of the law enforcement equipment.
[0040] However, this setup makes the installation process complex and cumbersome, requiring sequential steps such as fixing the display screen to the mid-frame, connecting the display unit to the rear cover, and sealing the panel, which consumes a significant amount of time. Furthermore, repairing or replacing parts requires disassembling multiple components, which is tedious and can easily damage other parts, affecting the normal operation of the equipment and hindering rapid assembly and repair.
[0041] The main purpose of this utility model is to propose a law enforcement device 100, which aims to simplify the structure of the display screen and improve installation and maintenance efficiency.
[0042] Please see Figures 1 to 8 In one embodiment of this utility model, the law enforcement device 100 includes a main housing 1 and a display screen assembly 2. The display screen assembly 2 includes a rear end cover 21, a display screen 22, and a panel 23. The rear end cover 21 is rotatably connected to the main housing 1. The rear end cover 21 includes an integrally formed bottom shell 211 and a support portion 212. The support portion 212 is disposed on the periphery of the bottom shell 211 and surrounds the bottom shell 211 to form an accommodating space 213. A support surface 2121 is formed on the side of the support portion 212 facing away from the bottom shell 211. The display screen 22 is disposed on the panel 23. The periphery of the panel 23 is supported by the support surface 2121 and covers the opening of the accommodating space 213 so that the display screen 22 is located within the accommodating space 213.
[0043] In this embodiment, the display screen 22 is disposed on the panel 23 and can be pre-assembled by means of adhesive, snap-fit, or screws, etc., which is not limited here. Then, the periphery of the panel 23 is connected to the support portion 212 of the rear cover 21, so that the rear cover 21 is supported on the support surface 2121 and covers the receiving space 213 of the rear cover 21, thereby placing the display screen 22 within the receiving space 213 to complete the installation of the display screen.
[0044] Understandably, the support 212 and the base shell 211 are integrally molded to improve structural strength and reduce the number of parts. The seamless integration between the base shell 211 and the support 212 effectively prevents dust, moisture, and other foreign matter from entering the accommodating space 213, providing excellent protection for the display screen 22 and related circuit components, thus improving equipment reliability. Simultaneously, this design makes the display screen assembly 2 more compact, contributing to the overall miniaturization and weight reduction of the law enforcement equipment 100.
[0045] Optionally, to further enhance the sealing performance of the display assembly 2, a sealing strip or other sealing structure may be provided between the panel 23 and the support surface 2121. The sealing strip can fill the tiny gap between the panel 23 and the support surface 2121 to prevent foreign objects from entering the accommodating space 213, while also providing a certain degree of cushioning and shock absorption to protect the display 22 from external impacts.
[0046] The technical solution of this utility model eliminates the need for a middle frame structure by using an integrally formed bottom shell and support part. During installation, the display screen is first pre-assembled with the panel, and then the panel is placed directly on the support surface of the support part, ensuring that the panel covers the accommodating space formed by the bottom shell and the support part. This completes the installation of the display screen. This not only simplifies the installation process and improves installation efficiency, but also facilitates maintenance and replacement of parts, solving the problem of complex display screen installation structure in existing law enforcement equipment.
[0047] In existing law enforcement equipment 100, the display screen 22 typically uses a relatively delicate and fragile material, such as a liquid crystal display (LCD) or an organic light-emitting diode display (OLED). These displays are quite sensitive to stress during installation. When the middle frame fixes the display screen 22, the rigid constraint of the middle frame will generate significant stress around the display screen 22, which can easily cause slight deformation of the display screen 22, thereby affecting its display effect, such as image distortion and uneven color.
[0048] To address the above problems, in one embodiment, please refer to... Figure 4 A first gap 221 is formed between the periphery of the display screen 22 and the side of the support 212 facing the accommodating space 213.
[0049] In this embodiment, the first gap 221 can solve the problem of minor errors that may occur during the installation of the display screen 22, and ensure that the display screen 22 and the support 212 will not generate installation stress due to excessive tightness, thereby improving the convenience of installation.
[0050] Understandably, the first gap 221 also provides a certain expansion space for the display screen 22, preventing damage due to lack of space for expansion and contraction when the display screen 22 undergoes thermal expansion and contraction. At the same time, the first gap 221 can also be used to accommodate sealant and other substances, further enhancing the connection strength and sealing performance between the display screen 22 and the support 212, preventing dust, moisture and other foreign objects from entering the accommodating space 213 from the gap between the periphery of the display screen 22 and the support 212, thus preventing damage to the internal components.
[0051] In one implementation, please refer to Figure 4 A second gap 222 is formed between the side of the display screen 22 facing the bottom shell 211 and the bottom shell 211.
[0052] In this embodiment, the second gap 222 provides space for the wiring of the display screen 22, allowing the wiring of the display screen 22 to be arranged within the second gap 222, avoiding clutter in the accommodating space 213, thereby improving the utilization rate of the accommodating space 213 and making the internal structure of the display screen assembly 2 more compact and orderly. At the same time, the second gap 222 can also prevent the display screen 22 from colliding with the bottom shell 211, reducing the risk of damage.
[0053] In one implementation, please refer to Figure 6 and Figure 7 The periphery of the support part 212 is provided with a limiting protrusion 2122 protruding from the support surface 2121. The periphery of the panel 23 is supported on the support surface 2121 and is limited and abutted against the limiting protrusion 2122.
[0054] In this embodiment, panel 23 is placed on support surface 2121. When the periphery of panel 23 contacts the limiting protrusion 2122, it indicates that panel 23 has reached the correct installation position. This eliminates the need for additional alignment processes, avoids the problem of panel 23 misalignment, and improves installation efficiency. It should be noted that the limiting protrusion 2122 is flush with the outer wall of support portion 212. When the limiting protrusion 2122 protrudes beyond the outer wall of support portion 212, it is prone to bumping or knocking. When the limiting protrusion 2122 is located inside support portion 212, it affects usability and is not aesthetically pleasing.
[0055] Understandably, the contact between the limiting protrusion 2122 and the periphery of the panel 23 forms a structure similar to a reinforcing rib. When the panel 23 is subjected to external force, such as a collision, the limiting protrusion 2122 can disperse and bear part of the external force, reducing the direct impact of the external force on the display screen 22 and internal components, thereby improving the structural strength of the display screen assembly 2 and extending the service life of the law enforcement equipment 100.
[0056] In one implementation, please refer to Figure 4The limiting protrusion 2122 protrudes from the support surface 2121 at a height that is the same as the thickness of the panel 23.
[0057] In this embodiment, the height of the limiting protrusion 2122 is the same as the thickness of the panel 23. That is, the side of the limiting protrusion 2122 facing away from the support surface 2121 is flush with the side of the panel 23 facing away from the support surface 2121. This allows the panel 23 to fit tightly against the support surface 2121 without any obvious gaps. This makes the appearance of the display assembly 2 more flat and aesthetically pleasing, while also ensuring uniform force distribution between the panel 23 and the support 212, thus improving the overall structural stability.
[0058] Optionally, the height of the limiting protrusion 2122 protruding from the support surface 2121 is slightly greater than the thickness of the panel 23. When the panel 23 is installed in place, the periphery of the panel 23 will be slightly squeezed by the limiting protrusion 2122, thereby achieving a tighter fit and further preventing the panel 23 from loosening during use.
[0059] In one implementation, please refer to Figure 4 , Figure 6 and Figure 7 The support part 212 is equipped with a weight reduction structure 2123.
[0060] In this embodiment, while ensuring the structural strength of the support 212, weight reduction is achieved by removing material from some non-critical load-bearing areas. The support 212 is equipped with a weight-reduction structure 2123 to reduce the weight of the display screen assembly 2, making the law enforcement equipment 100 lighter overall, easier for law enforcement personnel to carry and use, and reducing costs.
[0061] In one implementation, please refer to Figure 4 , Figure 6 and Figure 7 The weight reduction structure 2123 is a weight reduction groove formed by a recess on the side of the support part 212 facing the accommodating space 213, with the groove opening facing the accommodating space 213.
[0062] In this embodiment, the weight-reducing structure 2123 is a weight-reducing groove, and the groove opening is oriented towards the receiving space 213. This ensures that the weight-reducing groove reduces weight without affecting the appearance of the support 212 or the installation of the panel 23. Furthermore, the recessed area formed by the weight-reducing groove can also serve as additional storage space for placing auxiliary components or cushioning materials.
[0063] Understandably, weight reduction channels can be designed in different shapes and sizes to adapt to different stress requirements and component layouts.
[0064] In one implementation, please refer to Figure 4 , Figure 6 and Figure 7The weight-reducing structure 2123 is the weight-reducing inner cavity formed by the support part 212, so that the support part 212 is a hollow structure.
[0065] In this embodiment, by providing a weight-reducing inner cavity inside the support portion 212, the weight can be significantly reduced while maintaining the external shape of the support portion 212 without changing.
[0066] Understandably, reinforcing ribs or partitions can be added to the weight-reducing cavity to enhance the structural strength in specific directions.
[0067] In one embodiment, the support portion 212 has two oppositely arranged short sides 2124, and the weight reduction structure 2123 includes a plurality of weight reduction structures 2123 symmetrically arranged on the two short sides 2124.
[0068] In this embodiment, by symmetrically arranging multiple weight-reducing structures 2123, material in non-critical stress areas can be eliminated to the maximum extent. When the law enforcement device 100 is subjected to an external impact, the symmetrically distributed weight-reducing structures 2123 can evenly distribute the impact force to various parts of the support 212, reducing adverse effects on the display screen 22 and panel 23.
[0069] Understandably, the shapes of multiple weight-reducing structures 2123 can be set to the same shape, or they can be set to a gradual weight-reducing structure 2123 according to the force on different areas of the support 212. That is, more or larger weight-reducing structures 2123 are set in areas with less force, while fewer or smaller weight-reducing structures 2123 are set in areas with greater force.
[0070] In one implementation, please refer to Figure 5 , Figure 6 and Figure 7 The support portion 212 has a rotating opening 2125 on the side near the main housing 1. The rear cover 21 also includes a support housing 214 disposed on the bottom housing 211. The support housing 214 is connected to the support portion 212 and has a notch (unlabeled) corresponding to the rotating opening 2125. The support housing 214 and the support portion 212 enclose a rotating groove 2141, which communicates with the rotating opening 2125. A rotating component 24 is provided in the rotating opening 2125. One end of the rotating component 24 is inserted into the rotating groove 2141 and connected to the support housing 214. The other end of the rotating component 24 is located in the rotating opening 2125 and is rotatably connected to the main housing 1.
[0071] In this embodiment, one end of the rotating component 24 is connected to the supporting housing 214, and the other end of the rotating component 24 is rotatably connected to the main housing 1, thereby allowing the display screen assembly 2 to rotate relative to the main housing 1 about the axis of the rotating component 24. The rotatable connection between the rotating component 24 and the main housing 1 can be achieved using a structure combining a rotating shaft and a bearing; this structure is quite common and will not be described in detail here. This allows the display screen assembly 2 to freely adjust its angle within a certain range, facilitating law enforcement personnel to find the optimal viewing angle according to different law enforcement scenarios and lighting conditions.
[0072] Alternatively, one end of the rotating member 24 can be connected to the main housing 1, and the other end of the rotating member 24 can be rotatably connected to the support housing 214.
[0073] In one implementation, please refer to Figures 6 to 8 The supporting shell 214 is also provided with a supporting structure 2142 on the side opposite to the bottom shell 211. The supporting structure 2142 is flush with the supporting surface 2121, and the panel 23 is supported on the supporting surface 2121 and the supporting structure 2142.
[0074] In this embodiment, the support structure 2142 is a support groove recessed on the side of the support housing 214 facing the panel 23. It is understood that the bottom wall of the support groove is at the same horizontal plane as the support surface 2121 to ensure that when the panel 23 is closed over the opening of the accommodating space 213, the panel 23 remains horizontal and does not wobble. The side of the panel 23 closest to the main housing 1 is tightly fitted to the bottom wall of the support groove, ensuring the flatness of the panel 23 after installation. Simultaneously, the panel 23 is restrained and abutted against the side wall of the support groove, further limiting the displacement of the panel 23 in the horizontal and vertical directions, preventing the panel 23 from loosening due to external forces during use, thereby improving the overall stability of the display assembly 2.
[0075] Optionally, a buckle or limiting structure can be provided on the side wall of the support structure 2142 to cooperate with the corresponding structure on the panel 23, further enhancing the limiting effect of the panel 23 and making the installation of the panel 23 more reliable.
[0076] In one implementation, please refer to Figures 6 to 8 A wiring cavity 2143 is formed between the side of the support housing 214 facing the bottom housing 211 and the bottom housing 211. A wiring channel 2144 is also formed between the side of the support housing 214 near the main housing 1 and the support part 212. The wiring cavity 2143 communicates with the rotation port 2125 through the wiring channel 2144 and is coaxially arranged with the rotation groove 2141. The wiring of the display screen 22 passes sequentially through the wiring cavity 2143, the wiring channel 2144, and the rotation port 2125, and is electrically connected to the main housing 1.
[0077] In this embodiment, the support portion 212 has two symmetrically arranged rotating ports 2125 on the side near the main housing 1. A wire passage 2144 is provided on the side adjacent to the two rotating ports 2125, and a rotating groove 2141 is provided on the side away from each other. The wire passage 2144 is located between the two rotating ports 2125, facilitating wiring and ensuring that the rotating component 24 is installed within the rotating groove 2141 without affecting the wiring space. Furthermore, the rotating groove 2141 and the wire passage 2144 are coaxially arranged, ensuring that the wiring direction is parallel to the rotation direction. When the rotating component 24 rotates around its axis, the wiring within the wire passage 2144 will not rotate, preventing damage to the wiring due to torsion.
[0078] In one implementation, please refer to Figures 6 to 8 The support part 212 is also provided with an installation port 2127 on the side away from the main body shell 1. Two cameras 25 are rotatably installed in the installation port 2127. The two cameras 25 are coaxially arranged and face opposite directions.
[0079] In this embodiment, the two cameras 25 are coaxially arranged and face opposite directions, enabling shooting from both the front and rear without changing the orientation of the main body of the law enforcement equipment 100. This allows law enforcement officers to quickly record the situation from all angles. Furthermore, the rotatable camera 25 can adjust its shooting angle as needed, further improving shooting flexibility and enabling better capture of details.
[0080] Optionally, each camera 25 may also be equipped with a microphone and an indicator light, with the microphone used for listening to sound and the indicator light used to show whether the camera 25 is working properly.
[0081] In one implementation, please refer to Figure 6 and Figure 7 A cable passage cavity 2126 is provided between the support part 212 and the bottom shell 211. The cable passage cavity 2126 corresponds to the mounting port 2127. The wiring of the camera 25 is electrically connected to the display module through the cable passage cavity 2126.
[0082] In this embodiment, the cable passage cavity 2126 corresponds to the mounting port 2127, so that the wiring of the camera 25 can be directly led out from the mounting port 2127, pass through the cable passage cavity 2126, and finally connect to the display module. This reduces the problem of messy wiring and reduces the loss during signal transmission.
[0083] In one implementation, please refer to Figure 1 The main unit housing 1 has a cuboid structure. A touch area 11 and a button area 12 are formed on the side of the main unit housing 1 opposite to the display screen assembly 2. A heat dissipation vent 13 and a transmission port 14 are provided on the side wall of the main unit housing 1.
[0084] In this embodiment, the cuboid main casing 1 provides a stable foundation, facilitating the installation and fixation of other components. The touch area 11 and button area 12 allow law enforcement personnel to easily operate the law enforcement equipment 100, performing operations such as data input and function switching. The touch area 11 enables gesture operations such as zooming and swiping, while the button area 12 provides physical keypad typing input. The heat dissipation vent 13 dissipates heat from inside the main casing 1, ensuring the stability of the law enforcement equipment 100 during long-term operation and preventing performance degradation due to overheating. The transmission port 14 supports multiple data transmission protocols, such as USB and HDMI, facilitating data exchange with other devices, charging, or connection to external display devices, improving the versatility and expandability of the law enforcement equipment 100.
