Description

Technical Field

[0001] This invention relates to the field of power protection technology, specifically a reconfigurable power protection structure that can withstand bullets. Background Technology

[0002] Current military equipment is developing towards intelligence and new energy sources. As the primary power source, the safety of the power supply directly impacts the equipment's battlefield combat capability. During attacks on military equipment, vehicle-mounted power supplies are primarily threatened by bullets and shrapnel impacts, which not only compromise the power supply's own efficiency but also generate high levels of heat that seriously threaten the safety of equipment and personnel. Current battlefield ballistic protection mainly relies on high-performance fiber composite materials, high-performance ceramics and composite structures, and steel-fiber composite structures, focusing on overall protection or individual soldier equipment. It uses hard interception and soft absorption mechanisms to resist impacts, but research on customized protection for core power systems is limited.

[0003] Traditional armor materials suffer from insufficient heat dissipation and limited deformation restraint, making batteries susceptible to compression and impeded heat dissipation. Furthermore, impacts from bullets or shrapnel can easily trigger thermal runaway and explosions, causing instantaneous circuit failures, leading to equipment loss of control, loss of critical mission data, and severely hindering combat effectiveness. Therefore, the design of a protective structure for the core power system, namely the battery, is crucial. Current battery protection technologies often utilize integrated, universal armor shells, offering poor protection. Moreover, these structures require complete replacement after battlefield damage, making them unsuitable for rapid repair requirements in complex environments. Summary of the Invention

[0004] In order to solve the problems of poor protection effect of traditional battery protection structures and the need for complete replacement after being damaged on the battlefield, this invention provides a new reconfigurable power supply protection structure that can resist bullets.

[0005] This invention is achieved using the following technical solution: A reconfigurable power protection structure for bullet resistance includes a mounting frame with an upper opening, an insulation / heat dissipation layer with an upper opening, and a battery cover. The insulation / heat dissipation layer is fitted inside the mounting frame, and the battery is installed inside the insulation / heat dissipation layer. The battery cover is fixed to the upper opening of the insulation / heat dissipation layer. The battery cover has wiring holes that are adapted to the wiring terminals on the battery. A side mesh bag with its opening facing upward is fixed to the side wall of the mounting frame. A side high-hardness protective panel is installed inside the side mesh bag. A bottom mesh bag with its opening facing outward is fixed to the bottom of the mounting frame. A bottom high-hardness protective panel is installed inside the bottom mesh bag. The side high-hardness protective panels and the bottom high-hardness protective panels cover the side wall and bottom of the mounting frame.

[0006] Principle Explanation: The high-hardness side and bottom protective panels serve as the core bulletproof layers. Their high hardness effectively resists bullet penetration, preventing direct impact on the battery and thus avoiding loss of control of the aircraft equipment, loss of critical mission data, and severe constraints on combat effectiveness. Simultaneously, the design of the side and bottom mesh pockets allows the high-hardness protective panels to instantly enclose fragments upon impact, preventing secondary damage from high-speed scattering, forming a dual safety guarantee of "hard protection + soft restraint." Furthermore, the design of the mesh pocket openings facilitates timely and rapid replacement of broken high-hardness protective panels, achieving "tool-free maintenance," significantly shortening replacement time and reducing maintenance costs and material consumption. In addition, this power protection structure, as a power supply unit, is integrated into the military equipment, facilitating modular installation.

[0007] Furthermore, the battery and the insulation / heat dissipation layer are sized to fit each other, and there is filler between the insulation layer and the mounting frame. Due to environmental influences, the required wall thickness of the insulation layer varies (too thick a wall makes heat dissipation difficult), while since the size of the mounting frame is fixed, filler is provided between the insulation layer and the mounting frame to ensure that the battery does not swing back and forth relative to the mounting frame, thus affecting its service life.

[0008] Furthermore, the battery cover is equipped with heat dissipation holes to accelerate heat dissipation. This type of battery cover is used in conjunction with the heat dissipation layer and is suitable for power supply protection structures in high-temperature environments.

[0009] Furthermore, the cross-sections of the fixing frame and the insulation / heat dissipation layer are all square, there are four side mesh bags, and four side high-hardness protective panels, making the structure more specific and standardized.

[0010] Furthermore, the top end face of the insulation / heat dissipation layer is lower than the top end face of the mounting frame. After the battery cover is placed at the upper opening of the insulation / heat dissipation layer, its top surface is flush with the top end face of the mounting frame. The battery cover and the top end face of the mounting frame are pressed and fixed by cross-shaped adhesive tape extending downwards from its four ends to the four outer side walls of the mounting frame, forming a multi-point distributed bonding, which effectively improves the stability of the overall structure under vibration and impact conditions. The structure is simple, easy to assemble and disassemble, and lightweight.

[0011] Furthermore, the four outer side walls of the fixing frame are fixed to the four side mesh bags with Velcro, and the outer bottom wall of the fixing frame is fixed to the bottom mesh bag with Velcro. The structure is specific, standardized, and lightweight, making it easy to assemble and disassemble.

[0012] Furthermore, the inner surface of each side mesh bag is bonded and fixed to the upper surface of the fixing frame and battery cover with L-shaped tape, making the side mesh bags more secure.

[0013] Furthermore, the bottom mesh bag has its opening facing left. A high-rigidity protective panel is installed within the bottom mesh bag. One end of the bottom tape is adhered to the lower outer surface of the bottom mesh bag, bent upwards past the opening, and then adhered to the corresponding outer wall of the mounting frame. This bottom tape positions the high-rigidity protective panel, preventing misalignment during severe impacts or vibrations that could affect its protective effect. Additionally, this structure requires assembly in a "bottom first, then sides" sequence; that is, the bottom high-rigidity protective panel must be installed and positioned before the side high-rigidity protective panels are installed.

[0014] Furthermore, each side mesh bag is a cuboid mesh bag, and the cross-section of each of the three side end faces of each side mesh bag is oblong, with its length being longer than the corresponding side length of the fixing frame. The bottom mesh bag is a cuboid mesh bag, and the cross-section of the three side end faces of the bottom mesh bag (one side end face is exactly the bag opening) is semi-circular. The four side high-hardness protective panels and the bottom high-hardness protective panel are respectively matched with the shapes of the four side mesh bags and the bottom mesh bag, achieving full coverage of the fixing frame and effectively improving the impact resistance of the edges of the power supply chemical protection structure.

[0015] Furthermore, both the side high-hardness protective panel and the bottom high-hardness protective panel are ceramic panels, which can be selected from one of the following: boron carbide ceramic material, silicon carbide ceramic plate, alumina ceramic plate, boron nitride ceramic plate, silicon nitride ceramic plate, and silicon dioxide ceramic plate.

[0016] The beneficial effects of this invention are as follows: This invention uses a high-hardness protective panel as the core bulletproof layer, which effectively resists bullet penetration due to its high hardness. The design of the side and bottom mesh pockets can immediately wrap the fragments when the high-hardness protective panel is impacted and shattered, preventing secondary damage caused by high-speed splatter, forming a dual safety guarantee of "hard protection + soft constraint." Simultaneously, the fixing frame provides stable support, and the mesh pockets with elongated cross-sections fully cover the fixing frame, further improving the impact resistance of the structural edges. The modular design greatly optimizes maintenance, ease of use, and cost. The high-hardness protective panel adopts a pull-out assembly; when a side panel fails, there is no need to disassemble the entire structure. A single panel can be quickly replaced simply by using the corresponding pocket opening, achieving "tool-free maintenance," significantly shortening replacement time and reducing maintenance costs and material consumption.

[0024] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0025] like Figures 1-5 As shown, a reconfigurable power protection structure for resisting bullets includes a mounting frame 6 with an upper opening, an insulation / heat dissipation layer 5 with an upper opening, and a battery cover 3. The insulation / heat dissipation layer 5 is fitted inside the mounting frame 6, and a battery 4 is installed inside the insulation / heat dissipation layer 5. The battery cover 3 is fixed at the upper opening of the insulation / heat dissipation layer 5. The battery cover 3 is provided with wiring holes 11 that are adapted to the wiring terminals on the battery 4. A side mesh bag 2 with its opening facing upward is fixed on the side wall of the mounting frame 6. A side high-hardness protective panel 1 is installed inside the side mesh bag 2. A bottom mesh bag 7 with its opening facing outward is fixed to the bottom of the mounting frame 6. A bottom high-hardness protective panel 8 is installed inside the bottom mesh bag 7. The side high-hardness protective panels 1 and the bottom high-hardness protective panels 8 cover the side wall and bottom of the mounting frame 6.

[0026] Principle Explanation: The high-hardness protective panels 1 on the sides and 8 on the bottom serve as the core bulletproof layers. Their high hardness effectively resists bullet penetration, preventing direct impact from bullets on the battery 4, which could cause loss of control of the aircraft equipment, loss of critical mission data, and severe constraints on combat effectiveness. At the same time, the design of the side mesh pockets 2 and the bottom mesh pockets 7 allows the high-hardness protective panels to immediately enclose fragments when they are impacted and broken, preventing secondary damage caused by high-speed splashes, forming a dual safety guarantee of "hard protection + soft restraint". In addition, the design of the mesh pocket openings facilitates the timely and rapid replacement of broken high-hardness protective panels, achieving "tool-free maintenance", significantly shortening replacement time and reducing maintenance costs and material consumption. Furthermore, this power protection structure is placed as a whole in the military equipment as a power supply unit, which facilitates modular installation.

[0027] In practice, the battery 4 and the insulation / heat dissipation layer 5 are sized to match, and a filler is provided between the insulation layer and the fixing frame 6. Due to environmental influences, the required wall thickness of the insulation layer varies (too thick a wall makes heat dissipation difficult). Since the size of the fixing frame 6 is fixed, a filler is provided between the insulation layer and the fixing frame 6 to ensure that the battery 4 does not swing back and forth relative to the fixing frame 6, thus affecting its service life.

[0028] In practical implementation, the battery cover 3 is equipped with heat dissipation holes to accelerate the heat dissipation rate. This type of battery cover 3 is used in conjunction with the heat dissipation layer and is suitable for power supply protection structures in high-temperature environments.

[0029] In practice, the cross-sections of the fixing frame 6 and the insulation / heat dissipation layer 5 are square, there are four side mesh bags 2 and four side high-hardness protective panels 1, making the structure specific and standardized.

[0030] In practice, the top surface of the insulation / heat dissipation layer 5 is lower than the top surface of the fixing frame 6. After the battery cover 3 covers the upper opening of the insulation / heat dissipation layer 5, its top surface is flush with the top surface of the fixing frame 6. The battery cover 3 and the top surface of the fixing frame 6 are pressed and fixed by cross-shaped adhesive tape 9 extending downward to the four outer walls of the fixing frame 6 at its four ends, forming a multi-point distributed bonding, which effectively improves the stability of the overall structure under vibration and impact conditions. The structure is simple, easy to install and disassemble, and lightweight.

[0031] In practice, the four outer side walls of the fixing frame 6 are all fixed to the four side mesh bags 2 by Velcro (also called Velcro). The outer bottom wall of the fixing frame 6 is also fixed to the bottom mesh bag 7 by Velcro. The structure is specific, standardized, lightweight, and easy to assemble and disassemble.

[0032] In practice, the inner surface of each side mesh bag 2 is also bonded and fixed to the upper surface of the fixing frame 6 and the battery cover 3 with L-shaped tape 10, making the side mesh bag 2 more secure.

[0033] In practice, the bottom mesh bag 7 has its opening facing left. The bottom high-rigidity protective panel 8 is installed on the bottom mesh bag 7. One end of the bottom adhesive tape 12 is bonded to the lower outer surface of the bottom mesh bag 7, bent upwards through the opening of the bottom mesh bag 7, and then bonded to the corresponding outer wall of the fixing frame 6. The bottom adhesive tape 12 positions the bottom high-rigidity protective panel 8 to prevent it from shifting during severe impacts or vibrations, thus affecting its protective effect. In addition, this structure requires assembly to follow the "bottom first, then sides" sequence, that is, the bottom high-rigidity protective panel 8 is installed and positioned first, and then the side high-rigidity protective panels 1 are installed.

[0034] In practice, each side mesh bag 2 is a cuboid mesh bag, and the cross-section of each of the three side end faces (one side end face is exactly the bag opening) of each side mesh bag 2 is oblong, and its length is longer than the corresponding side length of the fixing frame 6. The bottom mesh bag 7 is a cuboid mesh bag, and the cross-section of each of the three side end faces (one side end face is exactly the bag opening) of the bottom mesh bag 7 is semi-circular. The four side high-hardness protective panels 1 and the bottom high-hardness protective panel 8 are respectively matched with the shapes of the four side mesh bags 2 and the bottom mesh bag 7, so as to achieve full wrapping of the fixing frame 6 and effectively improve the impact resistance of the edge of the power supply chemical protection structure.

[0035] In this specific embodiment, both the side high-hardness protective panel 1 and the bottom high-hardness protective panel 8 are ceramic panels, which can be selected from one or more of boron carbide ceramic materials, silicon carbide ceramic plates, alumina ceramic plates, boron nitride ceramic plates, silicon nitride ceramic plates and silicon dioxide ceramic plates.

[0036] In this specific embodiment, the fixing frame 6 is a carbon fiber fixing frame, which can be selected from high-strength carbon fiber (T300, T700, T800, etc.) or high-modulus carbon fiber.

[0037] In this specific embodiment, both the side mesh bag 2 and the bottom mesh bag 7 are soft composite materials based on woven fabrics, which can be woven from one or two high-strength woven fabrics such as aramid fiber and UHMWPE fiber.

[0038] The above description is merely a specific embodiment of the present invention, enabling those skilled in the art to understand or implement the present invention. Although detailed descriptions have been provided with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments, and they should all be covered within the protection scope of the claims.
