Description

Technical Field

[0001] This application relates to the technical field of explosion-proof and waterproof technology, specifically to a monitoring and identification device and its explosion-proof plastic structure. Background Technology

[0002] Currently, most surveillance and identification equipment used in riot control scenarios is concentrated in special industries, such as mines and flammable and explosive production environments. An IK10 riot control rating for surveillance cameras indicates that the camera's casing has an impact resistance rating exceeding level 10, meaning the casing can withstand more than 20J of energy five times, with no single point being impacted more than four times. The IK code is typically applied to the entire casing. If certain parts of the casing have different protection levels, their corresponding protection levels are marked. Table 1 shows the various riot control ratings, impact energies, and impact heights. Surveillance and identification equipment casings need to possess a certain level of protection to protect internal structures (such as lens modules) from harmful mechanical impacts.

[0005] Currently, most of the explosion-proof equipment on the market uses metal casings, which are not only costly but also have a limited range of applications, mostly applicable only to special industries.

[0006] The background description is provided for the purpose of understanding the relevant technologies in this field and is not intended as an admission of prior art. Summary of the Invention

[0007] Based on this, the present invention aims to provide a monitoring and identification device and its explosion-proof plastic structure to solve the problems of high cost and limited applicable scenarios caused by the use of metal materials in most traditional explosion-proof shells.

[0008] In a first aspect, embodiments of the present invention provide a blast-proof plastic structure, comprising: a plastic front shell, a plastic middle frame, and a metal rear cover;

[0009] A reinforcing layer is provided on the front side of the plastic front shell, and a plurality of protrusions are provided on the peripheral side of the plastic front shell, with a reinforcing part provided between each pair of adjacent protrusions.

[0010] The inner circumference of the plastic frame is provided with a plurality of grooves, each groove matching a corresponding protrusion; the plastic front shell and the plastic frame are assembled and connected by a plug-in structure consisting of protrusions and grooves.

[0011] The metal back cover is fixedly connected to the plastic front shell, and the plastic front shell, plastic frame and metal back cover form a sealed cavity.

[0012] Furthermore, the reinforcing layer includes multiple horizontal and vertical reinforcing ribs arranged perpendicularly to each other.

[0013] Furthermore, each of the reinforcing parts includes a first reinforcing rib, a second reinforcing rib, and a third reinforcing rib; the first reinforcing rib is disposed between two adjacent protrusions, the second reinforcing rib and the third reinforcing rib are obliquely disposed on the peripheral side of the plastic front shell, and the first reinforcing rib, the second reinforcing rib and the third reinforcing rib intersect at the same point.

[0014] Furthermore, the two ends of the second reinforcing rib are respectively connected to the corresponding protrusions via the fourth reinforcing rib and the fifth reinforcing rib; the two ends of the third reinforcing rib are respectively connected to the corresponding protrusions via the sixth reinforcing rib and the seventh reinforcing rib.

[0015] Furthermore, multiple reinforcing portions are evenly arranged on the peripheral side surface of the plastic front shell.

[0016] Furthermore, the gap between each of the reinforcing parts and the inner circumferential side of the plastic frame is ≤0.1mm.

[0017] Furthermore, each of the protrusions includes a connecting plate, and a first rib and a second rib disposed at both ends of the connecting plate; each of the grooves includes a first groove and a second groove; the first rib matches the first groove, and the second rib matches the second groove.

[0018] Furthermore, a waterproof ring is provided between the plastic front cover and the metal rear cover.

[0019] Furthermore, the metal rear cover and the plastic front cover are fixedly connected by a screw assembly.

[0021] In the blast-proof plastic structure used in this embodiment of the invention, the combination of a plastic front shell and a plastic middle frame increases the thickness of the structural sides, improving structural strength and blast-proof capability while reducing manufacturing difficulty. Multiple reinforcing parts located on the periphery of the plastic front shell further enhance the strength of the structural sides. These reinforcing parts are evenly distributed across the entire periphery of the plastic front shell, allowing for more uniform and rapid dispersal of external forces when the structure is subjected to them. This reduces the force at the stress points or stress surfaces, improving the structural sides' resistance to external forces and thus enhancing the blast-proof capability of the structure, ensuring overall structural integrity. The reinforcing layer on the front of the plastic front shell prevents the front of the structure from being affected by external forces, further improving the overall structural strength. The sealed cavity formed by the plastic front shell, plastic middle frame, and metal rear cover ensures the structure's waterproof capability.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings. Here, the illustrative embodiments and descriptions of this invention are used to explain the invention, but are not intended to limit the invention.

The term "based on" means "at least partially based on". The terms "one example embodiment" and "one embodiment" mean "at least one example embodiment".

[0031] Most surveillance and identification equipment used in riot control scenarios is concentrated in mines and flammable and explosive production environments. To protect the structural components from external damage, an outer casing is installed. To improve the strength and riot control capability of the casing, it is usually made of metal, resulting in high cost and a limited range of applicable scenarios. Meanwhile, the average wall thickness of the plastic parts in traditional surveillance and identification equipment is typically around 2.0mm. Excessive wall thickness makes manufacturing difficult due to limitations in plastic structure molds, while insufficient wall thickness results in insufficient strength, making it unsuitable for riot control scenarios. Therefore, this invention provides a riot-resistant plastic structure where the front shell and middle frame are made of plastic, and only the rear cover is made of metal. This reduces structural costs and expands the range of applicable scenarios. The combination of the plastic front shell and plastic middle frame increases the wall thickness of the structural sides, improving the strength and riot control capability of the structural sides.

[0032] In an embodiment of the present invention, Figure 1A schematic diagram of the various parts of the riot-proof plastic structure 1000 before assembly is shown. The riot-proof plastic structure 1000 includes a plastic front shell 1100, a plastic middle frame 1200, and a metal rear cover 1300. A reinforcing layer 1130 is provided on the front side of the plastic front shell 1100, and multiple protrusions 1110 are provided on the peripheral side of the plastic front shell 1100. A reinforcing part 1120 is provided between each adjacent protrusion 1110. Multiple grooves 1210 are provided on the inner peripheral side of the plastic middle frame 1200, and each groove 1210 matches a corresponding protrusion 1110. The plastic front shell 1100 and the plastic middle frame 1200 are assembled and connected by a plug-in structure formed by the protrusions 1110 and the grooves 1210. The metal rear cover 1300 is fixedly connected to the plastic front shell 1100, and the plastic front shell 1100, the plastic middle frame 1200, and the metal rear cover 1300 form a sealed cavity.

[0033] In one specific embodiment of the present invention, each of the reinforcing portions 1120 includes a first reinforcing rib 1121, a second reinforcing rib 1122, and a third reinforcing rib 1123; the first reinforcing rib 1121 is disposed between two adjacent protrusions 1110, the second reinforcing rib 1122 and the third reinforcing rib 1123 are obliquely disposed on the peripheral side surface of the plastic front shell 1100, and the first reinforcing rib 1121, the second reinforcing rib 1122 and the third reinforcing rib 1123 intersect at the same point, such as... Figure 2 As shown, a portion of the second reinforcing rib 1122 and a portion of the third reinforcing rib 1123 form a triangle with the top frame of the plastic front shell 1100, while another portion of the second reinforcing rib 1122 and another portion of the third reinforcing rib 1123 form a triangle with the bottom frame of the plastic front shell 1100. The triangle provides better stability, thereby improving the strength and riot protection capability of the plastic front shell 1100's periphery.

[0034] The first reinforcing rib 1121, the second reinforcing rib 1122, the third reinforcing rib 1123, the top and bottom frames of the plastic front shell 1100, and the protrusion 1110 form two trapezoids. To further improve stability and strength, the two ends of the second reinforcing rib 1122 are connected to the corresponding protrusion 1110 via the fourth and fifth reinforcing ribs, respectively; the two ends of the third reinforcing rib 1123 are connected to the corresponding protrusion 1110 via the sixth and seventh reinforcing ribs, respectively. Figure 1 and 2 As shown.

[0035] The structural design of the reinforcing part 1120 in this embodiment of the invention has two advantages:

[0036] On the one hand, it can prevent the concentration of external forces from causing structural damage: when the structure is subjected to external forces, the structure of the reinforcing part 1120 can decompose the external forces evenly and quickly (that is, decompose the external force at a certain point of the structure into forces in multiple directions, thereby reducing the external force at that point), thereby reducing the magnitude of the external force on the stress point or stress surface, reducing the impact of external forces on the structure, improving the structure's ability to resist external forces, and thus improving the strength and blast resistance of the structure.

[0037] On the other hand, it reduces the difficulty of the manufacturing process. Due to the influence of the plastic structure mold, the average wall thickness of the plastic parts cannot be too large, usually around 2.0mm, as excessive wall thickness leads to manufacturing difficulties. The strength advantage of the reinforcing part 1120 allows for a reduction in the wall thickness of the peripheral sides of the plastic front shell 1100, thus lowering the manufacturing difficulty. This structural design of the reinforcing part 1120 improves the ability to prevent damage from external forces, and its combination with the plastic middle frame 1200 increases the wall thickness of the structural sides, improving strength without increasing manufacturing difficulty. The side wall thickness of the plastic front shell 1100 combined with the plastic middle frame can reach approximately 5mm.

[0038] In one specific embodiment of the present invention, a plurality of reinforcing portions 1120 are evenly arranged on the peripheral side surface of the plastic front shell 1100, and the number of reinforcing portions 1120 is designed according to the overall structural length. For example, when the structural length is 183mm, six reinforcing portions 1120 are provided on each side of the long side of the plastic front shell 1100, and two reinforcing portions 1120 are provided on each side of the short side of the plastic front shell 1100.

[0039] In one specific embodiment of the present invention, after the plastic front shell 1100 and the plastic middle frame 1200 are assembled, the gap between each of the reinforcing parts 1120 and the inner circumferential side of the plastic middle frame 1200 is ≤0.1mm, preferably 0.1mm. The assembly gap maintained between the plastic front shell 1100 and the plastic middle frame 1200, preventing direct hard contact, can provide cushioning when subjected to external forces, further reducing the impact of external forces on the structure.

[0040] In one specific embodiment of the present invention, the reinforcing layer 1130 includes a plurality of mutually perpendicularly arranged transverse strip reinforcing ribs 1131 and longitudinal strip reinforcing ribs 1132, such as... Figure 3 As shown. The horizontal strip reinforcing rib 1131 is perpendicular to the long side of the plastic front shell 1100, and the vertical strip reinforcing rib 1132 is perpendicular to the short side of the plastic front shell 1100. The horizontal strip reinforcing rib 1131 and the vertical strip reinforcing rib 1132 are arranged perpendicular to each other, which ensures the strength of the front of the plastic front shell 1100 and thus improves the riot protection capability of the overall structure.

[0041] The plastic front shell 1100 includes a top frame, a bottom frame, and multiple protrusions 1110 located between the top frame and the bottom frame. The portion between the top frame and the bottom frame forms the peripheral side surface of the plastic front shell 1100. A front cover 1140 with triangular patterns is provided on the top frame. The front cover 1140, the top frame, the bottom frame, and the multiple protrusions 1110 constitute the plastic front shell 1100 with an open bottom. In this embodiment, the front cover 1140 and the top frame are an integral structure, and the cross-section of the front cover 1140 is an arc-shaped surface, which further strengthens the front strength of the structure and improves the front anti-riot capability.

[0042] The transverse strip reinforcing ribs 1131 and longitudinal strip reinforcing ribs 1132 of the reinforcing layer 1130 are located inside the top frame; the second reinforcing rib 1122 and the third reinforcing rib 1123 are inclinedly located between the top frame and the bottom frame.

[0043] In one specific embodiment of the present invention, each of the protrusions 1110 includes a connecting plate 1111, and a first rib 1112 and a second rib 1113 disposed at both ends of the connecting plate 1111; each of the recesses 1210 includes a first groove 1211 and a second groove 1212; the first rib 1112 matches the first groove 1211, and the second rib 1113 matches the second groove 1212. Figure 2 As shown, during assembly, each protrusion 1110 of the plastic front shell 1100 is aligned with the corresponding groove 1210, and then the first rib 1112 and the second rib 1113 of the protrusion 1110 are inserted into the first groove 1211 and the second groove 1212 respectively, thus completing the assembly between the plastic front shell 1100 and the plastic middle frame 1200. After assembly, an assembly gap is maintained between the reinforcing part 1120 on the peripheral side of the plastic front shell 1100 and the inner peripheral side of the plastic middle frame 1200 to provide cushioning.

[0044] After the plastic front shell 1100 and the plastic middle frame 1200 are assembled, the metal back cover 1300 is fixedly installed on the bottom frame of the plastic front shell 1100 by screw assembly. The plastic front shell 1100, the plastic middle frame 1200 and the metal back cover 1300 form a hollow and sealed cavity, forming a relatively waterproof environment, reaching the level of outdoor waterproof use. Figure 4 The assembled riot-proof plastic structure 1000 is shown.

[0045] To further improve the waterproof effect, a waterproof ring 1150 is provided between the plastic front cover 1100 and the metal back cover 1300.

[0046] Based on the unified inventive concept, this embodiment of the invention also provides a monitoring and identification device, including the aforementioned anti-riot plastic structure 1000, a camera assembly 1160 disposed inside the anti-riot plastic structure 1000, a camera hole disposed on the anti-riot plastic structure 1000, and a PC sheet 1170 disposed at the camera hole. The anti-riot plastic structure 1000 can prevent the camera assembly 1160 from being damaged by external forces and is waterproof, thus protecting the camera assembly 1160.

[0047] In a specific implementation, the camera assembly 1160 includes two or more cameras, an image processing module for processing the image information acquired by the two or more cameras, and a power supply module for providing power to the cameras and the image processing module.

[0048] The monitoring and identification device and its riot-proof plastic structure 1000 provided by this invention increase the thickness of the side of the structure by combining a plastic front shell 1100 and a plastic middle frame 1200, thereby improving the structural strength and riot-proof capability, while reducing the difficulty of manufacturing process. Multiple reinforcing parts 1120 provided on the periphery of the plastic front shell 1100 further improve the strength of the side of the structure. Since the reinforcing parts 1120 are evenly distributed across the entire periphery of the plastic front shell 1100, they can more evenly and quickly decompose external forces when the structure is subjected to external forces, reducing the external force at the stress point or stress surface, improving the ability of the side of the structure to resist external forces, and thus improving the riot-proof capability of the structure and ensuring the overall integrity of the structure. The reinforcing layer 1130 on the front of the plastic front shell 1100 prevents the front of the structure from being affected by external forces, further improving the strength of the entire structure. The sealed cavity formed by the plastic front shell 1100, the plastic middle frame 1200, and the metal rear cover 1300 ensures the waterproof capability of the structure.

[0049] The explosion-proof plastic structure 1000 of this invention, including the plastic front shell 1100 and the plastic middle frame 1200, are all made of plastic. Compared to a metal shell, this invention reduces manufacturing costs and the difficulty of the manufacturing process. Simultaneously, the combination of the plastic front shell 1100 and the plastic middle frame 1200, along with the reinforcing layer 1130 and the reinforcing part 1120, ensures structural strength, enabling the product to achieve the waterproof and explosion-proof rating required by special industries. Because the main body of the structure of this invention is made of plastic, it has a wider range of applications, covering most scenarios, such as civilian industries, outdoor environments, and harsh environments with poor security.
