Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0045] See Figures 1 to 6 This application provides a draped bulletproof and insulated box, including an equipment compartment 1 and a work compartment 2.

[0046] The equipment compartment 1 and the work compartment 2 are connected. Equipment compartment 1 houses the equipment needed for the bulletproof vehicle, while work compartment 2 houses the operating components of the equipment. For example, air conditioners, heaters, oxygen generators, generators, and communication equipment are placed in equipment compartment 1, while the electrical equipment corresponding to the generator and the communication equipment corresponding to the communication equipment are placed in work compartment 2. It is understood that the air conditioners, heaters, oxygen generators, generators, and communication equipment are merely illustrative examples and could be other equipment; this application does not limit this. This design avoids noise generated by the equipment affecting the work of personnel in work compartment 2. The interior of work compartment 2 serves as a personnel transfer and first-aid area, where first-aid equipment, casualty transport equipment, functional support equipment, and electrical systems can be installed.

[0047] Specifically, the equipment compartment 1 includes a frame 11 and a bulletproof protective layer 12. The frame 11 forms the supporting structure of the equipment compartment 1. The frame 11 can be a rectangular steel tube frame 11, a supporting structure formed by intersecting horizontal and vertical tubes. The bulletproof protective layer 12 is laid on the frame 11. The bulletproof protective layer 12 is used to protect the equipment placed inside the frame 11.

[0048] Furthermore, the bulletproof cladding layer 12 includes a first left side plate 121, a first right side plate 122, a first top plate 123, a first bottom plate 124, and a first front plate 125.

[0049] The first left side panel 121 and the first right side panel 122 are arranged opposite each other on both sides of the frame 11. The first left side panel 121 is provided with louvers 1211, and the first right side panel 122 is provided with a door that connects to the outside. In this way, ventilation can be carried out through the first left side panel 121, and the door on the first right side panel 122 can be used to enter the frame 11 for loading and maintenance of the equipment inside the frame 11.

[0050] The top phase angle of the first left side plate 121 and the first right side plate 122 is preferably 16°, the bottom phase angle is 8°, and the thickness of the first left side plate 121 and the first right side plate 122 is 4.6mm steel plate. The top phase angle of the first front plate 125 is preferably 39° and the thickness is 15mm steel plate.

[0051] The first top plate 123 is connected at both ends to the top edges of the first left side plate 121 and the first right side plate 122, respectively. A skylight is provided in the central area of ​​the first top plate 123. The skylight has bulletproof glass, allowing observation of the operation of the equipment inside the frame 11. The skylight can also be used for lighting.

[0052] The first base plate 124 is connected to the first left side plate 121 and the first right side plate 122 at both ends, and is used to support the equipment. The first base plate 124 has holes 1241 and other structures to allow for the installation of support frames 126 and other structures, creating multiple layers within the frame 11 so that different equipment can be placed on each layer. The holes 1241 are used to connect with the support frames 126, thus fixing the support frames 126. For example, the support corners of the support frames 126 are inserted into the holes 1241. The support corners are then fixed to the holes 1241 by welding or screwing.

[0053] The first front panel 125 is connected to the edges of the first left side panel 121, the first right side panel 122, the first top panel 123, and the first bottom panel 124, respectively. The first front panel 125 is provided with a heat dissipation vent 1251. The heat dissipation vent 1251 is used to dissipate heat from the equipment arranged within the frame 11. It should be noted that since the equipment compartment 1 is located in the vehicle's driving direction, airflow can enter the equipment compartment 1 through the heat dissipation vent 1251 during vehicle operation, thus dissipating heat from the equipment within the equipment compartment 1.

[0054] The work cabin 2 can accommodate items and personnel as needed. The work cabin 2 is an insulated, large-panel structure 21 container, with at least a portion of the outer side of the large-panel structure 21 covered with bulletproof protective cladding 3. The bulletproof cladding 3 provides bulletproof protection for the work cabin 2.

[0055] like Figure 6 As shown, specifically, the large panel structure 21 includes a first skin 211, a heat insulation layer 212, a metal frame 213, and a second skin 214.

[0056] A metal frame 213 is provided between the first skin 211 and the second skin 214, and a heat insulation layer 212 is filled between the metal frame 213.

[0057] Furthermore, the first skin 211 and the second skin 214 can be metal sheets of the same thickness or different thicknesses. For example, the first skin 211 and the second skin 214 are aluminum alloy sheets, and the thickness of the first skin 211 and the second skin 214 is 0.5-1mm. Preferably, the thickness of the first skin 211 and the second skin 214 is 0.8mm.

[0058] The first skin 211 and the second skin 214 are provided with a heat insulation layer 212 and a metal frame 213. The heat insulation layer 212 can be replaced with other heat-insulating materials; this application is not limited to this. Exemplarily, the heat insulation layer 212 is polyurethane foam. The metal frame 213 forms a support structure for supporting the first skin 211 and the second skin 214. The space between the frames of the metal frame 213 is filled with the heat insulation layer 212, thus providing a certain degree of insulation for the interior of the working chamber 2. Exemplarily, the metal frame 213 uses the same material as the first skin 211 and the second skin 214; that is, the metal frame 213 is made of aluminum alloy and can be formed by overlapping several aluminum rectangular tubes.

[0059] It should be noted that, due to the good thermal conductivity of the metal frame 213, heat insulation plates 215 are provided at the contact points between the metal frame 213 and the first skin 211, and between the metal frame 213 and the second skin 214 to prevent heat transfer from the metal frame 213. The heat insulation plates 215 block heat transfer between the metal frame 213 and the first skin 211, and between the metal frame 213 and the second skin 214, thereby further ensuring the temperature inside the working compartment 2. In addition, this also effectively reduces the weight of the compartment.

[0060] In this embodiment, the large panel structure 21 possesses excellent airtightness, thermal insulation, sound insulation, and properties such as waterproofing, fireproofing, heat radiation protection, salt spray corrosion resistance, and insect resistance. Through the rational arrangement and structural design of the metal frame 213 of the large panel, and by comprehensively considering the overall rigidity and weight of the carriage, the objectives of thermal insulation and sound insulation are achieved, fully demonstrating the superior performance of the carriage formed by the large panel structure 21. Heat-blocking panels (heat insulation boards 215) are installed at all frame positions on the inner lining (the contact points between the first skin 211 and the second skin 214 and the metal frame 213) of the large panel structure 21 to reduce heat loss from the carriage and improve its thermal insulation performance.

[0061] It should also be noted that the working compartment 2 includes a second front panel 22, a second left side panel 23, a second rear panel 24, a second right side panel 25, a second top panel 26, and a second bottom panel 27.

[0062] The second front panel 22, the second left side panel 23, the second rear panel 24, and the second right side panel 25 are connected in sequence to form the side wall of the working compartment 2. That is to say, the second front panel 22, the second left side panel 23, the second rear panel 24, and the second right side panel 25 together form the side wall of the working compartment 2.

[0063] The edge of the second top plate 26 is connected to the top edges of the second front plate 22, the second left side plate 23, the second rear plate 24, and the second right side plate 25, respectively. That is, the second top plate 26 serves as the top sealing structure of the side wall of the working compartment 2 and is connected to the top edge of the side wall of the working compartment 2.

[0064] Specifically, the second top plate 26 includes a front inclined plate 261, a left inclined plate 262, a rear inclined plate 263, a right inclined plate 264, and a top cover 265. The front inclined plate 261, left inclined plate 262, rear inclined plate 263, and right inclined plate 264 are connected sequentially, and the top edges of the front inclined plate 261, left inclined plate 262, rear inclined plate 263, and right inclined plate 264 are connected to the top cover 265. The bottom edges of the front inclined plate 261, left inclined plate 262, rear inclined plate 263, and right inclined plate 264 are correspondingly connected to the top edges of the second front plate 22, second left side plate 23, second rear plate 24, and second right side plate 25. The front inclined plate 261, left inclined plate 262, rear inclined plate 263, and right inclined plate 264 have the same slope; preferably, the normal phase angle is 61°. The thickness of the front inclined plate 261 and the rear inclined plate 263 is preferably 10 mm, and the thickness of the left inclined plate 262 and the right inclined plate 264 is preferably 4.6 mm.

[0065] The top cover 265 is equipped with a first observation window.

[0066] The edges of the second base plate 27 are connected to the bottom edges of the second front plate 22, the second left side plate 23, the second rear plate 24, and the second right side plate 25, respectively.

[0067] The second front panel 22, second left side panel 23, second rear panel 24, second right side panel 25, second top panel 26, and second bottom panel 27 together form a workspace for personnel transfer and first aid, as well as for the installation of first aid equipment, casualty transport equipment, functional support equipment, and electrical systems. The second front panel 22 is connected to the equipment compartment 1 and has multiple connecting windows 221 to connect the interior of the equipment compartment 1 and its internal workspace. The second top panel 26 has a first observation window. The second left side panel 23 and the second right side panel 25 have corresponding second observation windows. The connection between the second left side panel 23 and the second bottom panel 27, and the connection between the second right side panel 25 and the second bottom panel 27, are respectively provided with inwardly recessed grooves 28 to accommodate part of the wheels. The second rear panel 24 has a door with a third observation window.

[0068] The first, second, and third observation windows are all equipped with bulletproof glass. Preferably, the bulletproof glass is 55mm thick, and the type of bulletproof glass can be selected as needed; this application does not limit this selection. The first, second, and third observation windows are used not only for observation but also for light transmission.

[0069] The bulletproof drape 3 is fixed to the outer wall of the working cabin 2 by a buckle. The bulletproof drape 3 is a bulletproof steel plate with a thickness of 4-5mm. The bulletproof steel plate 32 has a frame 31 around its perimeter. The frame 31 protrudes from the bulletproof steel plate 32 so that when the bulletproof drape 3 is in close contact with the outer wall of the working cabin 2, a storage space is formed between the bulletproof steel plate 32 and the outer wall of the working cabin 2.

[0070] Among them, bulletproof steel plate 32 can be made of type 6252 bulletproof steel plate.

[0071] It should be noted that the position where the bulletproof cloak 3 overlaps with the second observation window has bulletproof glass, so that observation and lighting can be carried out through the second observation window and the bulletproof glass of the bulletproof cloak 3.

[0072] In this embodiment, the thermal insulation properties of the large panel structure 21, as well as its sound insulation, waterproofing, fireproofing, heat radiation protection, salt spray corrosion protection, and insect resistance, are utilized to improve the protective effect of the compartment. Furthermore, the metal frame 213 and the infill insulation layer 212 within the large panel structure 21 reduce the weight of the compartment while ensuring thermal insulation, allowing the advantages of the large panel structure 21 to be fully realized. The bulletproof cladding layer 12 and bulletproof cladding section 3, installed on the frame 11, provide protection for the equipment compartment 1 and the work compartment 2.

[0073] In addition, the bulletproof cladding structure (bulletproof cladding part 3 and bulletproof cladding layer 12) adopts a cladding-type bulletproof structure in the front, rear, left and right of the working compartment 2, achieving all-round protection in the front, rear and sides; the bulletproof cladding part 3 is made of 6252 bulletproof steel plate 32, which has excellent protective performance; the bulletproof cladding structure can be installed on the working compartment 2 and equipment compartment 1 by bolt connection, and when the bulletproof steel plate 32 is damaged, the damaged bulletproof steel plate 32 can be replaced without replacing the whole plate, saving costs and time.

[0074] In one embodiment, bulletproof strips (not shown in the figure) are installed inside the splicing gap formed between the second front plate 22, the second left side plate 23, the second rear plate 24, the second right side plate 25, the front inclined plate 261, the left inclined plate 262, the rear inclined plate 263, the right inclined plate 264, the top cover 265, and the second bottom plate 27. The bulletproof strips are arranged along the splicing gap. That is, bulletproof strips are installed at the splicing points of the plates, thus adding embedded bulletproof strips to all the joints of the plates, ensuring corresponding protection behind the joints, and increasing the protective capability of the splicing points.
