Description

Technical Field

[0001] This utility model relates to the field of mobile power technology, and more specifically, to a portable discharge device. Background Technology

[0002] With the diversification of modern life and the continuous growth in demand for portable power banks, the portable power bank market has experienced rapid development. Consumers have a particularly strong need for efficient and reliable power devices in outdoor activities, travel, and emergency power supply scenarios. Especially during outdoor use, portable power banks need to possess excellent ruggedness and reliability to withstand various harsh environments. Current energy storage technologies are evolving towards lightweighting, multi-functionality, and intelligence to meet users' needs for long-term power supply, fast charging, and compatibility with multiple devices. The shock resistance of these devices in complex outdoor environments is also crucial, directly affecting their reliability and lifespan.

[0003] Existing portable discharge devices typically use an outer shell combined with an internal fixing structure to protect the battery pack and other conversion components. Generally, the device uses a hard plastic or lightweight metal shell to provide physical protection, while its internal components are mostly fixed with rigid brackets. Although the structure has a certain structural strength, it lacks the ability to absorb and disperse vibrations and impacts from the external environment. Especially when used outdoors, the discharge device is prone to bumps and drops, which can easily cause secondary collisions between the internal circuits and battery modules and the outer shell, resulting in damage. In extreme cases, it may even cause short circuits or other safety hazards.

[0004] Therefore, there is a need to provide a portable discharge device to solve the problem that the aforementioned portable discharge devices lack the ability to absorb and disperse vibrations. Utility Model Content

[0030] Reference Figures 1 to 3 The present invention proposes a portable discharge device, comprising a detachably connected top shell 1 and a bottom shell 2, wherein a discharge assembly 3 is installed inside the top shell 1 and the bottom shell 2;

[0031] A plurality of buffer mechanisms 4 are provided between the bottom of the discharge assembly 3 and the bottom shell 2. Each buffer mechanism 4 includes a support plate 41 fixedly connected to the lower end face of the discharge assembly 3. Two symmetrically arranged support rods 42 are hinged to the lower end face of the support plate 41. The support rods 42 are slidably connected to the inner bottom wall of the bottom shell 2. Tensile elastic elements 43 are connected to the opposite sides of the two support rods 42. A fixing seat 44 is fixedly connected between the two tensile elastic elements 43. The fixing seat 44 is fixedly connected to the bottom shell 2.

[0032] In the above embodiments, the internal discharge component 3 is protected and encapsulated by the detachably connected top shell 1 and bottom shell 2, which not only facilitates the maintenance and replacement of components, but also ensures the overall sealing and safety of the equipment. In terms of equipment structure, the internal space of the top shell 1 and bottom shell 2 is rationally utilized, and the discharge component 3 is precisely installed therein, so that the entire device is lightweight and portable while also having sufficient stability and ease of operation.

[0033] The bottom of the discharge assembly 3 is connected to the bottom shell 2 via a buffer mechanism 4. Specifically, a support plate 41 is fixed to the lower end face of the discharge assembly 3, and its lower end face is slidably connected to the inner bottom wall of the bottom shell 2 via rotatable support rods 42. The support rods 42 are designed to be symmetrically arranged to ensure that they provide balanced and appropriate support when subjected to vertical or horizontal vibrations. To enhance the buffering effect, tensile elastic elements 43 are connected to the opposite sides of the two support rods 42. These elastic elements absorb and mitigate the impact force from the outside to a certain extent. The elastic elements are fixedly connected to each other by a fixing seat 44, so that the entire buffering system has good elastic recovery characteristics during vibration, while maintaining sufficient stability and positioning accuracy, effectively improving the adaptability and reliability of the device in harsh environments.

[0034] In summary, by setting a buffer mechanism 4 between the bottom of the discharge assembly 3 and the bottom shell 2, the shock resistance of the equipment is effectively improved. The bearing plate 41 in the buffer mechanism 4 is slidably connected to the bottom shell 2 through the rotating support rod 42, so that the discharge assembly 3 has a certain space to move when subjected to external impact. The sliding connection of the support rod 42 enables the equipment to obtain appropriate buffer support under impacts in different directions. The support rod 42, through the setting of the tension elastic element 43 and the fixed seat 44, realizes the dispersion and cancellation of vibration and impact force, effectively improving the overall shock resistance and impact resistance of the discharge device.

[0035] refer to Figure 3 In one embodiment, the buffer mechanism 4 further includes a hinge seat 45, which is fixedly disposed on the lower end face of the bearing plate 41 and is rotatably connected to the support rod 42.

[0036] In the above embodiments, the hinge seat 45 further enhances the flexibility and adaptability of the buffer mechanism 4. When subjected to impact, the hinge seat 45 allows for a certain angle change between the bearing plate 41 and the support rod 42, and provides support, thereby enabling the discharge assembly 3 to better absorb and disperse impact energy from different directions. This not only improves the shock resistance of the device but also ensures the stability and reliability of the discharge assembly 3 under extreme conditions.

[0037] In one embodiment, the buffer mechanism 4 further includes a roller 46, which is rotatably connected to the end of the support rod 42 away from the bearing plate 41, and the roller 46 is rolledly connected to the inner bottom wall of the bottom shell 2, so that the support rod 42 is slidably connected to the inner bottom wall of the bottom shell 2.

[0038] In the above embodiment, the roller 46 optimizes the operation mechanism of the buffer mechanism 4. When subjected to impact, the roller 46 can roll along the surface of the inner bottom wall of the bottom shell 2, thereby reducing friction and enabling the discharge component 3 to move and adjust its position more smoothly when subjected to impact. This ensures that the discharge component 3 can quickly return to a stable state under severe vibration or impact, avoiding damage or performance degradation caused by severe vibration.

[0039] In addition, the use of rollers 46 also has the effect of reducing noise. During the operation of the equipment, due to the rolling contact between rollers 46 and the inner bottom wall of the bottom shell 2, the noise generated by friction is reduced compared to the traditional sliding contact, making the equipment quieter during operation and improving the user experience.

[0040] refer to Figure 3 In one embodiment, a support assembly 5 is provided on the lower end face of the support plate 41. The support assembly 5 includes a telescopic rod 51. The two ends of the telescopic rod 51 are fixedly connected to the support plate 41 and the bottom shell 2, respectively. A compression elastic member 52 is sleeved on the outer side of the telescopic rod 51. The two ends of the compression elastic member 52 are fixedly connected to the support plate 41 and the bottom shell 2, respectively.

[0041] The telescopic rod 51 and the compression elastic element 52 together constitute the core part of the support assembly 5. The telescopic rod 51 allows the bearing plate 41 to shift to a certain extent when subjected to external impact, while the compression elastic element 52 provides the necessary elasticity during the extension and retraction of the telescopic rod 51 to help the bearing plate 41 quickly return to its original position. Furthermore, the compression elastic element 52 also absorbs impact energy. When the equipment is impacted, the compression elastic element 52 can absorb some of the impact energy, reducing the direct impact on the discharge assembly 3, thereby extending the service life of the equipment and further improving its stability and reliability.

[0042] refer to Figure 1 , Figure 2 and Figure 4 In one embodiment, the discharge assembly 3 includes a battery module 31, which is fixedly disposed on the upper surface of the support plate 41. The upper surface of the battery module 31 is provided with a control module 32, an interface module 33, and an inverter power conversion module 34. The control module 32 and the interface module 33 are respectively embedded in the upper surface of the top shell 1, and the inverter power conversion module 34 is disposed below the top shell 1.

[0043] Battery module 31, as the core component of discharge assembly 3, is responsible for storing and providing the electrical energy required for discharge. Control module 32 is responsible for the intelligent control of the entire discharge process. Through cooperation with interface module 33, it can achieve communication and data exchange with external devices, thereby enabling more flexible and intelligent discharge management. The inverter power conversion module 34 converts the DC power provided by battery module 31 into AC power suitable for the load, ensuring the stability and efficiency of the discharge process.

[0044] The discharge assembly 3 may also include a grid access terminal, a discharge connection device, a control power supply, a human-machine interface unit, a communication unit, a portable remote control unit, and a status detection module. The discharge connection device can be connected to the electric vehicle. The controller sends signals to the discharge control module 32 and the inverter control module 32. The discharge control module 32 controls the opening or closing of the discharge access terminal of the discharge connection device, and the inverter control module 32 controls the opening or closing of the inverter power conversion unit. The human-machine interface unit can display the discharge amount, discharge status, and other discharge information during the discharge process. Users can interact with the discharge process through the human-machine interface unit or a mobile APP.

[0045] In one embodiment, the battery module 31 is provided with heat dissipation fin arrays 6 on opposite sides, and a gap is provided between the heat dissipation fin arrays 6 and the side wall of the bottom shell 2 so that the battery module 31 and the bottom shell 2 form an air duct.

[0046] The heat dissipation fin array 6 can effectively improve the heat dissipation efficiency of the battery module 31. Since the battery generates heat during discharge, the heat dissipation fin array 6 forms an air duct through the gap between itself and the side wall of the bottom shell 2, allowing air to flow in the air duct and carry away the heat generated by the battery module 31.

[0047] In one embodiment, a fan assembly 7 is provided on one side of the battery module 31, a heat dissipation mesh 8 is provided on the top shell 1 covering the fan assembly 7, and an air inlet is provided at the end of the top shell 1 and the bottom shell 2 away from the heat dissipation mesh 8.

[0048] The fan assembly 7 includes a fan and a fan drive circuit. The fan is mounted on one side of the battery module 31, and the fan drive circuit controls the fan speed. When the fan is working, it draws air in through the air inlet, passes through the heat dissipation mesh 8, and blows it onto the battery module 31, thereby accelerating the heat dissipation process of the battery module 31. The air inlet design allows a continuous flow of external air into the fan assembly 7, ensuring the amount of air drawn in by the fan and thus improving heat dissipation efficiency.

[0049] In addition, the heat dissipation mesh 8 not only protects the fan and prevents foreign objects from entering the fan, but also filters dust in the air, reducing the damage of dust to the fan and battery module 31.

[0050] refer to Figure 5 In one embodiment, the bottom of the bottom shell 2 is covered with a flexible shock-absorbing pad 9, the flexible shock-absorbing pad 9 has a plurality of mounting holes, and an anti-slip pad 10 is provided in the mounting holes, the lower end surface of the anti-slip pad 10 protruding from the lower end surface of the flexible shock-absorbing pad 9.

[0051] The main function of the flexible shock-absorbing pad 9 is to absorb vibrations and impacts generated during the movement or transportation of the equipment, thereby protecting the internal battery module 31 and fan assembly 7 from damage. Since portable discharge devices often need to be moved between different working environments, the design of the shock-absorbing pad is crucial for improving the stability and durability of the equipment.

[0052] Furthermore, the anti-slip pad 10 further enhances the stability of the device on various surfaces. The lower end face of the anti-slip pad 10 protrudes beyond the lower end face of the flexible shock-absorbing pad 9, allowing the anti-slip pad 10 to directly contact the ground when the device is placed horizontally, thereby effectively preventing the device from sliding during operation. This design is particularly suitable for using portable discharge devices on uneven or smooth surfaces.

[0053] In one embodiment, a handle 11 is provided on one side of the top shell 1. The handle 11 is integrally formed with the top shell 1, and the surface of the handle 11 is provided with anti-slip texture.

[0054] The handle 11 not only facilitates gripping when carrying and moving the portable discharge device, but its one-piece molded structure also ensures a firm connection between the handle 11 and the top shell 1, thereby improving the overall structural strength. The anti-slip texture further enhances the user's comfort and safety when gripping the handle 11, especially in humid or oily industrial production environments, where the anti-slip texture effectively prevents hand slippage and ensures operator safety.

[0055] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
