Description
Technical Field
[0001] This application relates to the field of electronic device housing structure technology, and in particular to a power supply box metal housing. Background Technology
[0002] In today's rapidly evolving digital and intelligent world, power supply equipment, as the core energy hub of electronic systems, directly impacts the stable operation of various devices through its performance and reliability. From uninterruptible power supply systems in data centers to power supply modules for industrial automation equipment, and even power battery management systems for new energy vehicles, the application scenarios for power supply boxes are constantly expanding, and the market's requirements for their safety, heat dissipation, and ease of maintenance are becoming increasingly stringent. Metal casings, with their superior mechanical strength, electromagnetic shielding, and heat dissipation capabilities, have become the mainstream choice for power supply boxes, and innovative iterations in their structural design have become a key direction for continuous exploration in the industry.
[0003] A search revealed Chinese Patent Publication No. CN219873889U, which discloses an energy storage battery installation structure, relating to the field of energy storage battery installation technology. The structure includes a battery box shell, with two partitions fixedly connected to the inner walls of both sides of the shell, and an adjustment box fixedly connected between the two partitions. Two positioning seats are fixedly connected to the inner walls of both sides of the shell and the outer walls of both partitions, and each of the eight positioning seats has a sliding groove on one outer wall. Two battery bodies are disposed on the inner wall of the shell. This application facilitates rapid battery positioning by providing positioning seats within the battery box shell and using the cooperation between the positioning seats and positioning strips on the battery bodies. The adjustment box between the two partitions allows for direct pushing of the clamping seat to clamp and fix the battery through the cooperation between the bidirectional screw, threaded sleeve, and adjustment plate within the adjustment box. The clamping plate further facilitates battery installation within the battery box.
[0004] The aforementioned patent specification mentions that "the positioning seat and the positioning strip on the battery body cooperate to facilitate quick positioning of the battery, and an adjustment box is set between the two partitions. The cooperation between the bidirectional screw, threaded sleeve and adjustment plate in the adjustment box facilitates direct pushing of the clamping seat to clamp and fix the battery, and the clamping plate facilitates the installation of the battery in the battery box." The above-mentioned method can directly push the clamping seat to clamp and fix the battery, and the clamping plate facilitates the installation of the battery in the battery box. Although some of the devices are securely connected, they require a lot of time during equipment maintenance or troubleshooting, resulting in extremely low disassembly and assembly efficiency, loosening or even falling off, affecting the sealing and protective performance of the casing. Therefore, a metal casing for the power supply box is proposed to solve the above problems. Utility Model Content
[0005] The purpose of this application is to provide a metal housing for a power supply box, which aims to improve the problem of low disassembly and assembly efficiency.
[0006] The power supply box metal housing provided in this application adopts the following technical solution: A power supply box metal housing includes a cover plate, a heat dissipation mechanism is provided on the outside of the cover plate, a housing body is fixedly connected to the outside of the heat dissipation mechanism, a quick-release mechanism is provided inside the housing body, an outer shell is provided outside the quick-release mechanism, a protective mechanism is provided inside the cover plate, the quick-release mechanism includes a connecting block, the connecting block is fixedly connected to the outside of the outer shell, a sliding block is fixedly connected to the outside of the connecting block, a sliding ball is slidably connected to the outside of the sliding block, and a locking mechanism is provided on the outside of the housing body. Through the above technical solution: during operation, the heat generated by the internal components of the power box is transferred to the heat dissipation mechanism through the cover plate to achieve the heat dissipation effect. The protective mechanism isolates dust from the inside out, buffers impact, provides structural support, and insulates against electric shock. When disassembly or assembly is required, the sliding ball of the quick-release mechanism is pushed, which slides outside the sliding block and compresses the locking mechanism to lock, effectively improving the performance and practicality of the metal shell of the power box.
[0007] Preferably, the heat dissipation mechanism includes a heat-conducting layer, the heat-conducting layer is fixedly connected to the outside of the cover plate, and a water collection box is fixedly connected to the outside of the heat-conducting layer; By adopting the above technical solution, when the internal components of the power supply box generate heat, the heat is first conducted to the heat-conducting layer that is fixedly connected to the outside of the cover plate. Utilizing the excellent thermal conductivity of the heat-conducting layer, the heat is quickly transferred to the water collection box. The water collection box dissipates the heat through heat exchange by contacting the outside air, thereby cooling the inside of the power supply box and improving the stability and reliability of the power supply box during long-term operation.
[0008] Preferably, the locking mechanism includes a limiting post, the limiting post being fixedly connected to the inside of the housing body, and a buffer spring being sleeved on the outside of the limiting post; By adopting the above technical solution, when it is necessary to disassemble the outer shell and the main body of the housing, the sliding ball is pushed, and the sliding ball squeezes the buffer spring sleeved outside the limiting post, so that the buffer spring is compressed and the limiting post is driven to retract inward against the spring force, thereby releasing the lock between the main body of the housing and the outer shell. During installation, the sliding ball is released, and the buffer spring, which has lost the external force, restores its deformation and pushes the limiting post out with its own elasticity, and re-inserts it into the corresponding limiting hole of the connecting block, so as to achieve a stable connection between the outer shell and the main body of the housing, thereby improving the maintenance efficiency and safety of the metal housing of the power supply box.
[0009] Preferably, the buffer spring is externally fixedly connected to the outside of the sliding ball, and the buffer spring is externally fixedly connected to the outside of the housing body; By adopting the above technical solution, when disassembling the outer shell and main body of the power box metal casing, the sliding ball is manually pushed. The sliding ball compresses the buffer spring. Since the two ends of the buffer spring are fixedly connected to the sliding ball and the outside of the main body of the casing respectively, the spring is compressed, and the elastic potential energy increases. At the same time, it drives the limiting post that cooperates with the buffer spring to retract inward, thereby releasing the lock between the main body of the casing and the outer shell. During installation, the sliding ball is released, and the buffer spring releases its elastic potential energy. With the structure that is fixedly connected at both ends, the elastic force generated by its own deformation is transferred to the sliding ball, pushing the limiting post to extend again and lock into the corresponding connection structure, thereby achieving a stable lock between the main body of the casing and the outer shell.
[0010] Preferably, a fixing plate is fixedly connected to the outside of the water collection box, an inlet is fixedly connected to the inside of the fixing plate, and multiple partitions are fixedly connected to the outside of the water collection box. By adopting the above technical solution, when the heat dissipation mechanism is working, the water collection box absorbs the heat transferred by the heat-conducting layer and dissipates heat to the air. Water vapor in the air condenses into water droplets on the surface of the water collection box upon encountering the cold air. At this time, the partition strips on the outside of the water collection box guide the condensate to flow along a specific path, preventing large-area accumulation of condensate from affecting the heat dissipation efficiency. If it is necessary to improve the heat dissipation effect, coolant can be injected through the liquid inlet fixedly connected to the external fixing plate of the water collection box. The coolant enters the water collection box for circulation, enhancing the heat exchange process.
[0011] Preferably, the protective mechanism includes a protective functional layer, an anti-drop layer is fixedly connected to the outside of the protective functional layer, and a support structure layer is fixedly connected to the outside of the anti-drop layer. By adopting the above technical solution, when the power supply box is affected by the external environment, the protective mechanism begins to function. The innermost protective layer is the first to prevent dust, fine particles and other foreign objects from entering the power supply box, ensuring the cleanliness of the internal components. When subjected to external impact, the shock-proof layer absorbs the impact force through its own elastic deformation, buffering the damage to the power supply box from external forces. The supporting structure layer provides mechanical support for the entire protective mechanism, evenly distributing external pressure, avoiding local stress concentration, and improving the protective performance and durability of the power supply box's metal shell.
[0012] Preferably, an insulating protective layer is fixedly connected to the outside of the supporting structure layer, the insulating protective layer is fixedly connected to the outside of the housing body, and the protective functional layer is fixedly connected to the inside of the cover plate. By adopting the above technical solution, when the power supply box is running, the protective functional layer fits tightly against the inside of the cover plate, isolating external dust, moisture, and other impurities to prevent them from entering the power supply box; the shock-proof layer absorbs energy through its own deformation when subjected to external impact, reducing damage to internal components; the support structure layer provides stable support for the entire protection system and evenly distributes external pressure. The insulating protective layer is fixed to the outside of the support structure layer and connected to the main body of the casing, effectively preventing the main body of the casing from becoming electrified, avoiding the risk of electric shock to operators, and simultaneously isolating external electric fields from interfering with the internal circuitry.
[0013] Preferably, the outer shell includes a sealing and waterproof layer, the outer side of which is fixedly connected to the outside of the connecting block, and an impact-resistant buffer layer is fixedly connected to the outer side of the sealing and waterproof layer; By adopting the above technical solution, when the power supply box is in operation, the sealed waterproof layer of the outer shell tightly adheres to the connecting block, forming a tight seal at the joints. This effectively prevents rainwater, moisture, and dust from entering the power supply box, preventing circuit components from malfunctioning due to moisture or dust accumulation. Simultaneously, the impact-resistant buffer layer on the outside of the sealed waterproof layer continues to function. When the power supply box is subjected to impacts, drops, or other external forces, the impact-resistant buffer layer absorbs energy through its own elastic deformation, mitigating the impact on the internal structure.
[0014] In summary, this application includes at least one of the following beneficial technical effects: 1. By linking the sliding ball, sliding block, buffer spring and limiting post, the quick disassembly and installation of the main body and the outer shell are realized. During disassembly, pushing the sliding ball compresses the spring and causes the limiting post to retract and unlock, which is convenient and labor-saving. After installation, the sliding ball is released and the spring force drives the limiting post to lock automatically, ensuring a stable connection, improving maintenance efficiency, shortening maintenance time, and avoiding the problems of easy loss of parts and cumbersome disassembly and assembly of traditional screw fixing methods. It significantly enhances the practicality and convenience of the power box metal shell. 2. Through the coordinated operation of a multi-layer structure, efficient heat dissipation and condensation management are achieved. The heat-conducting layer quickly conducts heat, and the water collection box combines coolant circulation and air heat exchange for dual heat dissipation. The partition prevents condensate buildup from interfering with heat dissipation, and the liquid inlet supports coolant replenishment, ensuring the long-term operation of the heat dissipation system. It quickly reduces the internal temperature of the power supply box, preventing components from degrading in performance or being damaged due to overheating. Furthermore, by guiding condensate and circulating coolant, it solves the problems of water accumulation and efficiency degradation in traditional heat dissipation systems, effectively improving the stability and service life of the power supply box under high load operation.

[0016] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6 This application will be described in further detail below.
[0017] Example: A metal casing for a power supply box, as shown in the reference. Figures 1 to 3 The power supply box includes a cover plate 1, which is in direct contact with the outside world and provides initial protection. It is also an important channel for heat dissipation. A heat dissipation mechanism 6 is provided on the outside of the cover plate 1. The heat dissipation mechanism 6 is responsible for efficiently dissipating the heat generated inside the power supply box, maintaining the stable operating temperature of the internal components, and preventing performance degradation or failure due to overheating. The heat dissipation mechanism 6 is fixedly connected to the outer shell body 2, which carries the internal electronic components and provides mechanical support. The main body 2 is equipped with a quick-release mechanism 4 inside. The quick-release mechanism 4 is used to quickly disassemble and install the main body 2 and the outer shell 3, which facilitates the inspection and replacement of the internal components of the power box and improves maintenance efficiency. The outer shell 3 is provided outside the quick-release mechanism 4. The cover plate 1 is equipped with a protective mechanism 5 inside. The protective mechanism 5 is used to protect the internal components of the power box from multiple dimensions such as dust prevention, drop prevention, and insulation to ensure the safe operation of the power box. The quick-release mechanism 4 includes a connecting block 41, which is used to ensure the overall structural stability of the quick-release mechanism 4. The connecting block 41 is externally fixedly connected to the inside of the outer shell 3. A sliding block 42 is externally fixedly connected to the connecting block 41. The sliding block 42 is used to provide a sliding track for the sliding ball 43 and guide the movement direction of the sliding ball 43. The sliding ball 43 is externally slidably connected to the sliding block 42. The sliding ball 43 is used to unlock the device by pushing it manually. It is the triggering component of the quick-release mechanism 4. The operation is convenient and labor-saving. The outer side of the housing body 2 is provided with a locking mechanism 44. The locking mechanism 44 is used to lock and unlock the outer shell 3 and the housing body 2, ensuring the stability of the overall structure of the power box during normal use. The buffer spring 441 is externally fixed to the outside of the sliding ball 43. The buffer spring 441 is externally fixed to the outside of the housing body 2. The outer casing 3 includes a sealed waterproof layer 31. The sealed waterproof layer 31 is made of sealing material and forms a tight waterproof and dustproof barrier at the seams to prevent rainwater, moisture, dust and other substances from entering the power box. The sealed waterproof layer 31 is fixedly connected to the outside of the connecting block 41. An impact-resistant buffer layer 32 is fixedly connected to the outside of the sealed waterproof layer 31. The impact-resistant buffer layer 32 is made of elastic buffer material. When the power box is subjected to external impacts such as collisions or drops, it absorbs energy through its own deformation, reduces the impact force on the internal components, and improves the power box's resistance to external damage. Specifically, the metal casing of the power supply box uses an aluminum alloy cover plate 1 as a top barrier, which not only blocks foreign objects but also conducts heat through its high thermal conductivity. The heat is quickly transferred to the aluminum alloy water collection box 61 through the copper heat conduction layer 63 of the heat dissipation mechanism 6. The coolant in the box circulates and dissipates heat through the inlet 65. The partition 62 guides the condensate to drain. The main body of the casing 2 is made of stainless steel to provide high-strength support. The internal quick-release mechanism 4 slides on the track of the sliding block 42 through the sliding ball 43. The compression spring steel buffer spring 441 enables quick assembly and disassembly. The EPDM rubber sealing waterproof layer 31 of the outer shell 3 fits tightly against the connecting block 41 to resist moisture and dust. The external polyurethane impact-resistant buffer layer 32 absorbs energy through deformation when impacted. The polycarbonate protective functional layer 51 of the protective mechanism 5 is dustproof, the silicone drop-proof layer 52 buffers impact, the carbon fiber support structure layer 53 disperses pressure, and the epoxy resin insulating protective layer 54 prevents leakage. All structures work together to ensure the stable operation of the power box in complex environments.
[0018] Reference Figure 4 and Figure 6The heat dissipation mechanism 6 includes a heat-conducting layer 63, which is fixedly connected to the outside of the cover plate 1. A water collection box 61 is fixedly connected to the outside of the heat-conducting layer 63. The water collection box 61 exchanges heat with the air and dissipates heat to the external environment. At the same time, it collects the condensate generated during the heat dissipation process to prevent water accumulation from affecting the heat dissipation effect. A fixing plate 64 is fixedly connected to the outside of the water collection box 61. The fixing plate 64 is used to fix the liquid inlet 65, provide structural support for the addition of coolant, and enhance the overall strength of the water collection box 61. The fixed plate 64 has an internal fixed connection to a liquid inlet 65, which can be filled with coolant. The coolant circulates in the water collection box 61, which further improves heat dissipation efficiency. It is suitable for high-power, long-term operation power supply scenarios. The water collection box 61 has multiple partitions 62 externally fixed connections. The partitions 62 are used to guide the flow of condensate and direct the condensate to a specific location for discharge or collection. The heat-conducting layer 63 is made of a material with high thermal conductivity, which can quickly absorb the heat generated by the internal components of the power supply box. The protective mechanism 5 includes a protective functional layer 51, which is used to directly contact the internal components of the power supply box. Its main function is to isolate foreign objects such as dust and fine particles. A drop-proof layer 52 is fixedly connected to the outside of the protective functional layer 51. The drop-proof layer 52 is made of cushioning material. When the power supply box is subjected to external force such as drop or collision, it absorbs energy through its own elastic deformation, reduces the impact of the impact on the internal components, and protects the components from damage. A support structure layer 53 is fixedly connected to the outside of the drop-proof layer 52. The support structure layer 53 ensures that the protective functional layer 51 and the drop-proof layer 52 will not deform or shift when subjected to external force. An insulating protective layer 54 is fixedly connected to the outside of the support structure layer 53. The insulating protective layer 54 is used to prevent the power supply box shell from becoming electrified and avoid the risk of electric shock to the operator. The insulating protective layer 54 is fixedly connected to the outside of the shell body 2, and the protective functional layer 51 is fixedly connected to the inside of the cover plate 1. Specifically, the heat dissipation and protection systems of this power supply box work together to ensure stable operation of the equipment in complex environments. The copper heat-conducting layer 63 of the heat dissipation mechanism 6 is in close contact with the aluminum alloy cover plate 1, quickly absorbing internal heat and conducting it to the aluminum alloy water collection box 61. The coolant inside the box is injected and circulated through the inlet 65, enhancing heat exchange efficiency. The surface partition strip 62 guides the condensate to flow into the drainage channel along a specific path, preventing water accumulation from affecting heat dissipation. The protective functional layer 51 of the protection mechanism 5 isolates dust, the silicone anti-drop layer 52 buffers impact, the carbon fiber support structure layer 53 disperses stress, and the epoxy resin insulating protective layer 54 eliminates the risk of leakage. The five-layer structure is compounded in sequence, forming a complete protection system from dust prevention, impact resistance, support to insulation, ensuring the safe operation of the power supply box under harsh conditions such as high temperature, vibration, and humidity.
[0019] The implementation principle of this application embodiment is as follows: When the internal components of the power supply box generate heat, the heat is transferred to the heat-conducting layer 63 through the cover plate 1. Due to the good thermal conductivity of the heat-conducting layer 63, the heat can be quickly absorbed. The heat continues to be conducted to the water collection box 61. The surface of the water collection box 61 is in contact with the air and dissipates the heat to the surrounding environment through heat exchange. Water vapor in the air condenses into water droplets on the surface of the water collection box 61 when it is cooled. The partition strip 62 can guide the flow of condensate to prevent water accumulation from affecting the heat dissipation effect. The coolant can be injected through the liquid inlet 65 inside the fixing plate 64. The coolant circulates in the water collection box 61 to further improve the heat dissipation efficiency.
[0020] When it is necessary to disassemble or install the housing body 2 and the outer shell 3, push the sliding ball 43. The sliding ball 43 slides outside the sliding block 42 and compresses the buffer spring 441 at the same time. This causes the limiting post 442 to retract inward against the elastic force of the buffer spring 441. After the limiting post 442 retracts, it releases the lock on the housing body 2 and the outer shell 3, allowing them to be separated or installed. After installation, release the sliding ball 43. Under the elastic force of the buffer spring 441, the limiting post 442 extends and re-inserts into the corresponding limiting hole of the connecting block 41, thus achieving a stable connection between the housing body 2 and the outer shell 3. The protective functional layer 51 is in direct contact with the inside of the cover plate 1, isolating external factors that may affect the inside of the power box. The drop-proof layer 52 absorbs the impact force through its own buffering and deformation when the power box is subjected to external impact or drop. The support structure layer 53 provides structural support for the entire protective mechanism 5, avoiding excessive local pressure from damaging the internal components. The insulating protective layer 54 prevents the main body 2 of the shell from becoming electrified, avoiding the risk of electric shock to the operator. The sealing and waterproof layer 31 is tightly attached to the connecting block 41 to prevent moisture and liquid from seeping into the inside of the power box. The impact-resistant buffer layer 32 absorbs the impact energy through its own elastic deformation, reducing the impact force on the internal components of the power box and reducing the risk of component damage.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
