Abstract
Description
Technical Field
[0001] This utility model relates to the field of emergency power supply technology, and in particular to a novel emergency power supply device. Background Technology
[0002] Emergency power supply units, as key devices providing temporary power supply in municipal, industrial, and household power systems, are widely used in scenarios such as sudden power outages and protection of critical loads. With the increasing demands for power supply continuity and stability across industries, emergency power supply units face higher technical requirements in terms of functional integration, structural compactness, and heat dissipation reliability. Especially in high-power applications, the continuous operation of internal components in emergency power supply units leads to significant heat accumulation. If heat cannot be dissipated effectively and promptly, it will not only affect the system's performance stability but may even pose safety hazards. Therefore, reasonable and efficient heat dissipation design has become an indispensable and crucial aspect of emergency power supply unit design.
[0003] In existing technologies, emergency power supply devices typically employ cooling fans and ventilation holes for heat dissipation. Specifically, conventional structures often use cooling fans to directly draw outside air into the device, creating airflow circulation. This airflow carries away heat from the surface of the heating elements, and the hot air is then expelled through the vents to lower the internal temperature. Additionally, some devices incorporate simple filters at the air inlet to prevent large particles from entering. However, in pursuit of increased ventilation, some designs sacrifice filtration precision, allowing fine dust to enter with the air. Over time, this accumulation can negatively impact the normal operation of electrical components and the efficiency of heat dissipation.
[0004] However, in the aforementioned traditional structure, relying solely on a cooling fan for airflow exchange and lacking adequate dust protection, dust particles are easily drawn directly into the emergency power supply unit, accumulating on the surfaces of electrical components. This reduces heat dissipation efficiency and increases the risk of electrical short circuits or malfunctions. Furthermore, the simple dust filter design makes cleaning and replacement inconvenient and maintenance costs high. Therefore, existing emergency power supplies suffer from limited heat dissipation and are susceptible to dust contamination under high-temperature, long-term operation, leading to performance degradation and shortened lifespan. Improvements are urgently needed to enhance their practicality and reliability. Utility Model Content

[0007] The dustproof component includes a dustproof net, which is disposed on one side of the cooling fan.

[0013] The emergency power supply body has a shell fixedly connected to its outer wall, a fixing column fixedly connected to the inside of the shell, and a locking block fixedly connected to the inside of the shell.
[0014] As a further description of the above technical solution:
[0015] The outer wall of the fixed column is rotatably connected to a storage tray, and the storage tray has a slot inside.
[0016] As a further description of the above technical solution:
[0017] The storage tray is equipped with a torsion spring. One end of the torsion spring is fixedly connected to the inside of the storage tray, and the other end of the torsion spring is fixedly connected to the inside of the fixing post.
[0018] As a further description of the above technical solution:
[0019] The housing has a groove inside, and a sliding plate is provided inside the housing. The sliding plate is slidably connected inside the groove, and a top block is fixedly connected to the top of the groove.

[0021] An N-shaped frame is fixedly connected to the outer wall of the skateboard, and a protrusion is fixedly connected to one end of the N-shaped frame. The protrusion engages with the locking block.
[0022] This utility model has the following beneficial effects:
[0023] 1. In this utility model, the cooling fan first draws external air into the emergency power supply body after filtering it through the dust filter. The cool air is then blown onto the outer wall of the components inside the emergency power supply body, carrying away the heat. The hot air is then discharged through the air outlet, achieving the effects of heat dissipation and dust prevention, and facilitating the cleaning of the filter. This solves the problem that the internal heat generation of the emergency power supply device is huge during use, and the traditional heat dissipation structure easily draws in dust, thus improving the practicality of the emergency power supply device.
[0024] 2. In this utility model, the sliding plate pushes downward to release the cable, and then the torsion spring rebounds and releases energy to drive the storage tray to rotate, thereby driving the cable to be stored on the outer wall of the storage tray, which achieves the effect of convenient cable storage. This solves the problem that the cables of the emergency power device are exposed and inconvenient to store, and improves the convenience of the emergency power device. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0034] Reference Figures 1-3 The present invention provides an embodiment of a novel emergency power supply device, comprising an emergency power supply body 1. The emergency power supply body 1 is an HQ-EP series emergency power supply, which is existing technology and will not be described in detail here. A cooling fan 2 is fixedly connected inside the emergency power supply body 1. The cooling fan 2 is used to draw external cold air into the emergency power supply body 1 to enhance the heat dissipation effect of the internal components. An air outlet 10 is provided inside the emergency power supply body 1 to discharge internal hot air in a timely manner to prevent temperature accumulation. A dustproof component is provided on one side of the emergency power supply body 1 to filter external impurities during air flow and prevent dust from entering the interior.
[0035] The dustproof component includes a dustproof mesh 6, which is located on one side of the cooling fan 2. The dustproof mesh 6 provides initial filtration of incoming air, preventing larger particles from entering the emergency power supply unit 1, thus improving the overall cleanliness and stability of the device. A fixing ring 5 is fixedly connected to the outer wall of the dustproof mesh 6 to stabilize its position and ensure consistent and reliable dustproof performance. A frame 7 is slidably connected to the outer wall of the fixing ring 5, facilitating the disassembly and installation of the dustproof component and improving maintenance convenience. A magnet 8 is fixedly connected inside the frame 7, attracting a magnet 4 inside the emergency power supply unit 1 to form a stable positioning structure. A magnet 4 is also fixedly connected inside the emergency power supply unit 1, providing magnetic attraction to quickly fix and disassemble the dustproof component, improving replacement and cleaning efficiency. The attraction between magnet 4 and magnet 8 ensures stable positioning of the frame 7 during use, preventing the dustproof component from loosening due to vibration. A seal is provided on one side of the frame 7. The components include a sealing component to further seal the connection gaps and prevent fine dust particles or moisture from entering the interior. A limiting component is provided on one side of the emergency power supply body 1 to guide and restrict the installation position of the frame 7, ensuring accurate and reliable installation. The limiting component includes a limiting ring 3, one side of which is fixedly connected to one side of the emergency power supply body 1. The limiting ring 3 guides and limits the outer contour of the frame 7, improving the assembly accuracy and firmness of the dustproof component. The frame 7 is slidably connected inside the limiting ring 3, facilitating quick movement and disassembly of the frame 7 during maintenance or replacement. The sealing component includes a sealing ring 9, one side of which is fixedly connected to one side of the frame 7. During installation, the sealing ring 9 forms a tight fit with one side of the emergency power supply body 1, further improving the sealing performance of the dustproof component and preventing air leakage or dust infiltration. The sealing ring 9 fits against one side of the emergency power supply body 1, ensuring the overall sealing and protection level of the device and extending the service life of internal components.
[0036] Reference Figures 4-6The emergency power supply body 1 has a housing 11 fixedly connected to its outer wall. The housing 11 protects and supports the internal structure, ensuring the stability and reliability of the overall device. A fixing column 12 is fixedly connected inside the housing 11. The fixing column 12 serves as a central support, supporting and limiting the rotation axis position of the storage tray 13. A locking block 20 is fixedly connected inside the housing 11. The locking block 20 limits and locks the sliding structure, improving the stability and safety of the overall components. The storage tray 13 is rotatably connected to the outer wall of the fixing column 12. The storage tray 13 is used to store power cables, facilitating cable organization and storage, and preventing exposed cables from affecting the cleanliness of the equipment. The storage tray 13 has a slot 14 inside, which is used to cooperate with the subsequent drive structure to limit the starting position of the rotation of the storage tray 13 and prevent it from spinning freely or sliding in the opposite direction. A torsion spring 15 is installed inside the storage tray 13. The torsion spring 15 provides the storage tray 13 with a rebound driving force for automatically winding up the cable, improving the convenience and neatness of cable management. One end of the torsion spring 15 is fixedly connected to the inside of the storage tray 13. By fixing one end to the storage tray 13, the torque is transmitted and the storage tray 13 has a self-resetting function. The other end of the torsion spring 15 is fixedly connected to the inside of the fixing post 12. By fixing the other end to the fixing post 12, the torsion spring 15 is ensured to contract and release... During the placement process, a stable rebound torque is formed. A groove 16 is provided inside the housing 11 to guide the sliding plate 17 to slide in a specific direction, ensuring accurate trajectory during sliding and preventing deviation and jamming. The sliding plate 17 is installed inside the housing 11. The sliding plate 17 triggers and controls the storage function through sliding, improving operational flexibility. The sliding plate 17 is slidably connected inside the groove 16, allowing it to move smoothly along the inner wall of the groove 16, improving the stability and responsiveness of the structure. A top block 21 is fixedly connected to the top of the groove 16, limiting the movement of the sliding plate 17 and preventing it from sliding... 17. During the sliding process, if the sliding exceeds the set range, the safety and reliability of the overall device operation are ensured. An N-shaped frame 18 is fixedly connected to the outer wall of the slide plate 17. The N-shaped frame 18 is used to strengthen the structural strength of the slide plate 17 and realize the cooperation operation with other components, thereby improving the overall force performance. A protrusion 19 is fixedly connected to one end of the N-shaped frame 18. The protrusion 19 serves as a linkage control component and is used to achieve a locking connection with the locking block 20. Locking and releasing are achieved through mechanical limiting. The protrusion 19 and the locking block 20 are engaged. Through the engagement of the two, the slide plate 17 can be effectively locked in the non-operational state to prevent accidental sliding and improve the stability and safety of the overall structure.
[0037] Working principle: When using this new emergency power supply device, when the emergency power supply body 1 is used to dissipate heat, the cooling fan 2 draws outside air into the emergency power supply body 1 after it is filtered by the dustproof net 6. The cool air is blown towards the outer wall of the components inside the emergency power supply body 1, and the heat is carried away. The hot air is then discharged through the air outlet 10. The dustproof net 6 is supported by the fixing ring 5 and installed on one side of the cooling fan 2 by the frame 7. The frame 7 and the emergency power supply body 1 are attracted by the magnetic force of magnet 1 4 and magnet 2 8 and are limited by the limiting ring 3 to prevent misalignment. This achieves the effect of heat dissipation, dust prevention and easy cleaning of the filter.
[0038] When using the cable, the slide plate 17 slides downward within the groove 16, separating the top block 21 from the cable. The cable is then pulled out of the housing 11. As the cable is pulled out, it causes the storage tray 13 to rotate and stores force in the torsion spring 15. When the cable is fully pulled out, the slide plate 17 slides upward within the groove 16. The N-shaped bracket 18 drives the protrusion 19 to engage with the top of the locking block 20, fixing the slide plate 17 in place. The top block 21 clamps and fixes the cable. When storing the cable, the slide plate 17 pushes downward to release the cable. Then, the torsion spring 15 rebounds, releasing energy to rotate the storage tray 13, thereby storing the cable on the outer wall of the storage tray 13, achieving the effect of convenient cable storage.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
