Description

Technical Field

[0001] This utility model relates to the field of energy storage power supply, specifically to a portable small energy storage power supply. Background Technology

[0002] Energy storage power is a device that can store electrical energy and release it when needed. It is an indispensable core device in energy transition and power system. Its core function is to solve the time and space mismatch problem of "generation-storage-use" of electricity. It is widely used in backup power, renewable energy integration and grid peak shaving. Energy storage power is classified according to energy storage medium: electrochemical energy storage, lead-acid battery and sodium-ion battery.

[0003] Existing portable small energy storage power supplies often suffer from poor structural stability in their casings. The connections between components are not robust or reliable enough, making them prone to loosening during daily use or transportation, affecting their overall lifespan and safety. Furthermore, these power supplies are inconvenient to carry and place; either they lack a structure that facilitates movement, making handling difficult, or their mounting structure is poorly designed, occupying considerable space when not in use. In addition, the casing is usually exposed, lacking effective protective structures, making it susceptible to damage from dust and other factors. Even when simple protective components are provided, their positions are difficult to adjust flexibly according to usage needs, causing inconvenience to users and impacting the user experience. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned defects and provide a portable small energy storage power supply. By using a rotating shaft shield, it solves the technical problem that the position of the simple shielding component in the prior art is difficult to adjust flexibly according to the usage requirements.

[0005] The objective of this utility model is achieved through the following means:

[0006] A portable small energy storage power supply includes a housing. A display screen is mounted on the upper front of the housing, and control buttons are evenly distributed below the display screen. Power supply interfaces are evenly distributed below the control buttons. Heat dissipation vents are located at the center of both sides of the housing. A connecting upper seat and a connecting lower seat are respectively mounted on the upper and lower surfaces of the housing. Fixing posts are mounted around the upper surface of the connecting lower seat, with the tops of the fixing posts extending upwards through the housing and the connecting upper seat. Fixing rods are inserted around the upper parts of the fixing posts, and compression springs are installed between the inner ends of the fixing rods and the inner walls of the fixing posts. Threaded screws are rotatably connected to the front and rear ends of both sides of the housing. An external connecting handle is mounted at the top of the threaded screw, and a sliding block is fitted on the surface of the threaded screw. A universal pulley is connected directly below the sliding block. A T-shaped seat is rotatably connected to the center of the upper surface of the connecting upper seat. Side connecting seats are mounted on the front and rear ends of both sides of the T-shaped seat. A rotating shaft is rotatably connected to the upper inner surface of the side connecting seat. A baffle plate is mounted on the front of the rotating shaft, and a triangular top plate is added above the rotating shaft.

[0007] When not in use, the portable small energy storage power supply has an integral basic structure. The display screen at the top of the front, the control button and power interface at the bottom are idle. The heat dissipation vents in the center of both sides allow for natural air circulation. The top of the fixing posts around the upper surface of the connecting base penetrates the outer shell and the connecting base. The fixing rod extends out of the fixing post surface under the elastic force of the compression spring, limiting and fixing the connecting base. The sliding blocks on the threaded screws at the front and rear ends of both sides of the outer shell are located at the top. The universal pulleys are located in the inner cavity of the outer shell and are suspended in the air, not in contact with the ground. The T-shaped seat in the center of the upper surface of the connecting base can rotate freely. The rotating shaft on the side connecting base drives the shield. Under the action of the triangular top plate, the shield is in a relatively stable position, which can provide a certain degree of protection for the structure below.

[0008] When the energy storage power supply needs to be moved, rotate the outer connecting handle at the top of the threaded screw at the front and rear ends of both sides of the outer casing. The threaded screw rotates accordingly, causing the sliding block sleeved on its surface to move downward along the threaded screw. The universal pulley connected directly below the sliding block moves downward until it contacts the ground. At this time, the energy storage power supply can be moved by pushing the universal pulley. During the movement, the direction can be adjusted by rotating the T-shaped seat at the center of the upper surface of the connecting seat for easy operation.

[0009] If it is necessary to disassemble, maintain or replace parts of the energy storage power supply, press the fixing rods on the upper part of the fixing column. The fixing rods will compress the springs and move into the fixing column, releasing the limit on the connecting upper seat, and the connecting upper seat can be separated from the outer shell.

[0010] During use, if the external environment may affect the display screen and other components, rotate the upper pivot on the inner side of the side connector. The pivot will drive the shield to rotate, and the triangular top plate can support the shield. Adjust the shield to a suitable angle to block external debris or light and protect the display screen and control buttons.

[0011] Furthermore, the power supply interface has sliding grooves on both sides, a protective plate is slidably connected to the front of the power supply interface, and sliding protrusions are installed on both sides of the back of the protective plate, with the sliding protrusions slidably connected to the sliding grooves.

[0012] The sliding grooves on both sides of the power supply interface provide a sliding path for the sliding protrusions on both sides of the back of the protective front plate. The protective front plate can cover or expose the front of the power supply interface by sliding the sliding protrusions in the sliding grooves.

[0013] Furthermore, a protective single plate is inserted and connected to the front of the protective plate, and the protective single plate corresponds to the corresponding power supply interface.

[0014] The protective panel inserted on the front of the protective plate is positioned to correspond to the power supply interface, and the specific power supply interface is blocked by inserting it.

[0015] Furthermore, positioning blocks are installed on both sides of the protective panel, and positioning grooves are evenly provided on the inner wall of the protective panel, with the positioning blocks and positioning grooves slidably connected.

[0016] The positioning blocks on both sides of the protective panel are embedded in the positioning grooves on the inner wall of the protective panel. By sliding the positioning blocks in the positioning grooves, the position of the protective panel on the protective panel can be adjusted and fixed.

[0017] Furthermore, plug-in frames are installed at the center of both sides of the outer casing, and filter elements are inserted into the inner cavity of the plug-in frames. The plug-in frames are connected to the heat dissipation vents.

[0018] The insertion frames at the center of both sides of the outer casing provide space for the filter element. After the filter element is inserted into the inner cavity of the insertion frame, it filters the airflow entering through the heat dissipation port through the connection between the insertion frame and the heat dissipation port.

[0019] Furthermore, a limiting groove is formed around the top of the fixed column, and a limiting plate is slidably connected to the top of the limiting groove. The limiting plate is connected to the corresponding fixed rod.

[0020] The limiting grooves around the top of the fixed column provide a sliding base for the limiting plate. The limiting plate slides at the top of the limiting groove and, through connection with the corresponding fixed rod, achieves relative fixation between the fixed rod and the fixed column.

[0021] The beneficial effects of this utility model are: the connecting upper seat on the upper surface of the outer shell and the connecting lower seat on the lower surface cooperate with the fixing posts around the upper surface of the connecting lower seat. The top of the fixing post extends upward through the outer shell and the connecting upper seat. The interaction between the fixing rod inserted at the upper part of the fixing post and the compression spring between the fixing rod and the inner wall of the fixing post can enhance the overall structural stability of the outer shell and make the connection between the components more firm and reliable.

[0022] The screw threaded screws rotatably connect the front and rear ends of both sides of the outer casing, and are combined with the external connecting handle at the top, the sliding block sleeved on the surface, and the universal pulley connected directly below the sliding block. The position of the universal pulley can be adjusted by rotating the external connecting handle. When a mobile power supply is needed, the universal pulley can be put down for easy carrying and transportation. When no movement is required, the universal pulley can be folded up to save storage space.

[0023] The T-shaped base is rotatably connected to the center of the upper surface of the upper seat. The upper part of the inner side of the side connecting seats on both sides is rotatably connected to the shaft. With the cover plate on the front of the shaft and the triangular top plate above the shaft, the cover plate can protect the display screen and control buttons when the power supply is not in use. The triangular top plate can help fix the position of the cover plate. The rotation of the T-shaped base makes it easy to adjust the direction of the cover plate according to the usage needs, further improving the convenience of using the power supply.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0032] In this embodiment, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The portable small energy storage power supply specifically implemented includes a housing 1. A display screen 2 is installed on the upper front of the housing 1. Control buttons 3 are evenly distributed below the display screen 2. Power supply interfaces 4 are evenly distributed below the control buttons 3. Heat dissipation vents 13 are opened in the center of both sides of the housing 1. A connecting upper seat 5 and a connecting lower seat 6 are respectively installed on the upper and lower surfaces of the housing 1. Fixing posts 16 are installed around the upper surface of the connecting lower seat 6. The top of the fixing posts 16 extends upward through the housing 1 and the connecting upper seat 5. Fixing rods 17 are inserted into the upper part of the four sides of the fixing posts 16. A compression spring 18 is provided between the inner end of 7 and the inner wall of the fixed column 16. The front and rear ends of both sides of the outer shell 1 are rotatably connected to threaded screws 21. An outer connecting handle 22 is installed at the top of the threaded screw 21. A sliding block 23 is sleeved on the surface of the threaded screw 21. A universal pulley 24 is connected directly below the sliding block 23. A T-shaped seat 25 is rotatably connected to the center of the upper surface of the connecting seat 5. Side connecting seats 26 are installed on the front and rear ends of both sides of the T-shaped seat 25. A rotating shaft 28 is rotatably connected to the upper part of the inner side of the side connecting seat 26. A baffle plate 29 is installed on the front of the rotating shaft 28. A triangular top plate 27 is added above the rotating shaft 28.

[0033] When not in use, the portable small energy storage power supply has an outer shell 1 as the basic structure. The display screen 2 on the upper front, the control button 3 and the power supply interface 4 on the lower front are idle. The heat dissipation vents 13 on both sides can allow natural air circulation. The top of the fixing posts 16 around the upper surface of the connecting base 6 passes through the outer shell 1 and the connecting base 5. The fixing rod 17 extends out of the surface of the fixing post 16 under the elastic force of the compression spring 18, and limits and fixes the connecting base 5. The sliding blocks 23 on the threaded screws 21 at the front and rear ends on both sides of the outer shell 1 are located at the upper position. The universal pulleys 24 are suspended and do not contact the ground. The T-shaped seat 25 in the center of the upper surface of the connecting base 5 can rotate freely. The rotating shaft 28 on the side connecting seat 26 drives the shield 29. Under the action of the triangular top plate 27, the shield 29 is in a relatively stable position, which can provide a certain degree of protection for the structure below.

[0034] When the energy storage power supply needs to be moved, rotate the outer connecting handle 22 at the top of the threaded screw 21 at the front and rear ends of both sides of the outer casing 1. The threaded screw 21 rotates accordingly, causing the sliding block 23 sleeved on its surface to move downward along the threaded screw 21. The universal pulley 24 connected directly below the sliding block 23 moves downward until it contacts the ground. At this time, the energy storage power supply can be moved by pushing the universal pulley 24. During the movement, the direction can be adjusted by rotating the T-shaped seat 25 at the center of the upper surface of the connecting upper seat 5 for easy operation.

[0035] If the energy storage power supply needs to be disassembled for maintenance or parts replaced, press the fixing rod 17 on the upper part of the fixing post 16. The fixing rod 17 compresses the spring 18 and moves into the fixing post 16, releasing the limit on the connecting upper seat 5, and the connecting upper seat 5 can be separated from the outer shell 1.

[0036] During use, if the external environment may affect the display screen 2 and other components, rotate the shaft 28 on the upper inner side of the side connecting seat 26. The shaft 28 drives the shield 29 to rotate. The triangular top plate 27 can support the shield 29. Adjust the shield 29 to a suitable angle to block external debris or light and protect the display screen 2 and control button 3 and other structures.

[0037] The upper connecting seat 5 is connected and fixed to the outer shell 1 and the lower connecting seat 6 through the fixing post 16, the fixing rod 17 and the compression spring 18. Pressing the fixing rod 17 can release the fixation, which is convenient for quick disassembly and installation and is beneficial for later maintenance and component replacement.

[0038] like Figure 2 and Figure 5As shown, the power supply interface 4 has sliding grooves 7 on both sides. A protective plate 8 is slidably connected to the front of the power supply interface 4, and sliding protrusions 9 are installed on both sides of the back of the protective plate 8. The sliding protrusions 9 are slidably connected to the sliding grooves 7. The sliding grooves 7 on both sides of the power supply interface 4 provide a sliding path for the sliding protrusions 9 on both sides of the back of the protective plate 8. The protective plate 8 can cover or expose the front of the power supply interface 4 by sliding the sliding protrusions 9 in the sliding grooves 7. Through the sliding cooperation between the sliding protrusions 9 and the sliding grooves 7, the protective plate 8 can stably protect the power supply interface 4, reducing the probability of external dust and impurities directly contacting the power supply interface 4. The sliding connection method facilitates the opening and closing of the protective plate 8. A protective single plate 11 is inserted and connected to the front of the protective plate 8, and the protective single plate 11 corresponds to the power supply interface 4. The protective panel 11 inserted into the front of the protective plate 8 is positioned corresponding to the power supply interface 4, and the insertion connection achieves targeted shielding of the specific power supply interface 4. The protective panel 11 corresponds one-to-one with the power supply interface 4, which can provide more precise protection for a single power supply interface 4 on the basis of the overall protection of the protective plate 8. The insertion connection method allows for the individual installation and removal of the protective panel 11 as needed. Positioning blocks 12 are installed on both sides of the protective panel 11, and positioning grooves 10 are evenly opened on the inner wall of the protective plate 8. The positioning blocks 12 are slidably connected to the positioning grooves 10. The positioning blocks 12 on both sides of the protective panel 11 are embedded in the positioning grooves 10 on the inner wall of the protective plate 8. By sliding the positioning blocks 12 in the positioning grooves 10, the position of the protective panel 11 on the protective plate 8 can be adjusted and fixed. The sliding connection between the positioning blocks 12 and the positioning grooves 10 can limit the position of the protective panel 11 on the protective plate 8, prevent the protective panel 11 from shifting during use, and facilitate the adjustment of the insertion position of the protective panel 11 according to actual needs, thereby improving the connection stability.

[0039] like Figure 6 As shown, plug-in frames 14 are installed at the center of both sides of the outer casing 1. Filter elements 15 are inserted into the inner cavity of the plug-in frames 14, and the plug-in frames 14 are connected to the heat dissipation vents 13. The plug-in frames 14 at the center of both sides of the outer casing 1 provide space for the filter elements 15. After the filter elements 15 are inserted into the inner cavity of the plug-in frames 14, the airflow entering through the heat dissipation vents 13 is filtered through the connection between the plug-in frames 14 and the heat dissipation vents 13. The filter elements 15 can filter impurities in the air entering the outer casing 1, absorb moisture from the air, and reduce the adhesion of impurities to internal components. Furthermore, the insertion and connection method between the plug-in frames 14 and the filter elements 15 facilitates the periodic replacement of the filter elements 15, ensuring the filtration effect.

[0040] like Figure 3As shown, limiting grooves 19 are formed around the top of the fixed column 16. A limiting plate 20 is slidably connected to the top of the limiting groove 19, and the limiting plate 20 is connected to the corresponding fixed rod 17. The limiting grooves 19 around the top of the fixed column 16 provide a sliding base for the limiting plate 20. The limiting plate 20 slides at the top of the limiting groove 19 and, through connection with the corresponding fixed rod 17, achieves relative fixation between the fixed rod 17 and the fixed column 16. The sliding fit between the limiting plate 20 and the limiting groove 19 enhances the stability of the connection between the fixed rod 17 and the fixed column 16. The limiting function effectively prevents unnecessary displacement of the fixed rod 17 during use, and the sliding connection method facilitates adjustment of the position of the limiting plate 20 during installation.

[0041] The usage process of a portable small energy storage power supply in this embodiment is as follows: When the energy storage power supply is not in use, the outer shell 1 is the overall basic structure. The display screen 2 on the upper part of its front, the control button 3 and the power supply interface 4 are idle. The heat dissipation vents 13 on both sides can allow natural air circulation. The top of the fixing posts 16 around the upper surface of the connecting lower seat 6 penetrates the outer shell 1 and the connecting upper seat 5. The fixing rod 17 extends out of the surface of the fixing post 16 under the elastic force of the compression spring 18, and limits and fixes the connecting upper seat 5. The sliding blocks 23 on the threaded screws 21 at the front and rear ends on both sides of the outer shell 1 are located in the upper position. The universal pulley 24 is in a suspended state and does not contact the ground. The T-shaped seat 25 in the center of the upper surface of the connecting upper seat 5 can rotate freely. The rotating shaft 28 on the side connecting seat 26 drives the shield 29. Under the action of the triangular top plate 27, the shield 29 is in a relatively stable position, which can provide a certain degree of protection for the structure below.

[0042] When the energy storage power supply needs to be moved, rotate the outer connecting handle 22 at the top of the threaded screw 21 at the front and rear ends of both sides of the outer casing 1. The threaded screw 21 rotates accordingly, causing the sliding block 23 sleeved on its surface to move downward along the threaded screw 21. The universal pulley 24 connected directly below the sliding block 23 moves downward until it contacts the ground. At this time, the energy storage power supply can be moved by pushing the universal pulley 24. During the movement, the direction can be adjusted by rotating the T-shaped seat 25 at the center of the upper surface of the connecting upper seat 5 for easy operation.

[0043] If the energy storage power supply needs to be disassembled for maintenance or parts replaced, press the fixing rod 17 on the upper part of the fixing post 16. The fixing rod 17 compresses the spring 18 and moves into the fixing post 16, releasing the limit on the connecting upper seat 5, and the connecting upper seat 5 can be separated from the outer shell 1.

[0044] During use, if the external environment may affect the display screen 2 and other components, rotate the shaft 28 on the upper inner side of the side connecting seat 26. The shaft 28 drives the shield 29 to rotate. The triangular top plate 27 can support the shield 29. Adjust the shield 29 to a suitable angle to block external debris or light and protect the display screen 2 and control button 3 and other structures.

[0045] The upper connecting seat 5 is connected and fixed to the outer shell 1 and the lower connecting seat 6 through the fixing post 16, the fixing rod 17 and the compression spring 18. Pressing the fixing rod 17 can release the fixation, which is convenient for quick disassembly and installation, and is beneficial for later maintenance and component replacement.

[0046] The sliding grooves 7 on both sides of the power supply interface 4 provide a sliding path for the sliding protrusions 9 on both sides of the back of the protective plate 8. The protective plate 8 can cover or expose the front of the power supply interface 4 by sliding the sliding protrusions 9 in the sliding grooves 7.

[0047] The sliding engagement between the side sliding protrusion 9 and the side sliding groove 7 enables the protective plate 8 to stably protect the power supply interface 4, reducing the probability of external dust and impurities directly contacting the power supply interface 4. The sliding connection method also facilitates the opening and closing of the protective plate 8.

[0048] The protective single plate 11 inserted on the front of the protective plate 8 is positioned corresponding to the power supply interface 4, and the specific power supply interface 4 is blocked by the insertion connection.

[0049] The protective panel 11 corresponds one-to-one with the power supply interface 4, which can provide more precise protection for a single power supply interface 4 on the basis of the overall protection of the protective panel 8. The plug-in connection method makes it easy to install and remove the protective panel 11 individually as needed.

[0050] The positioning blocks 12 on both sides of the protective panel 11 are embedded in the positioning grooves 10 on the inner wall of the protective plate 8. The position of the protective panel 11 on the protective plate 8 can be adjusted and fixed by the sliding of the positioning blocks 12 in the positioning grooves 10.

[0051] The sliding connection between the positioning block 12 and the positioning groove 10 can limit the position of the protective plate 11 on the protective plate 8, prevent the protective plate 11 from shifting during use, and facilitate the adjustment of the insertion position of the protective plate 11 according to actual needs, thereby improving the connection stability.

[0052] The insertion frame 14 at the center of both sides of the outer casing 1 provides an insertion space for the filter element 15. After the filter element 15 is inserted into the inner cavity of the insertion frame 14, the airflow entering through the heat dissipation port 13 is filtered by the connection between the insertion frame 14 and the heat dissipation port 13.

[0053] The filter element 15 can filter impurities in the air entering the housing 1, absorb moisture in the air, and reduce the adhesion of impurities to the internal components. The insertion connection between the plug frame 14 and the filter element 15 facilitates the regular replacement of the filter element 15 and ensures the filtration effect.

[0054] The limiting grooves 19 around the top of the fixed column 16 provide a sliding base for the limiting plate 20. The limiting plate 20 slides at the top of the limiting groove 19 and is connected to the corresponding fixed rod 17 to achieve relative fixation between the fixed rod 17 and the fixed column 16.

[0055] The sliding fit between the limiting plate 20 and the limiting groove 19 can enhance the stability of the connection between the fixing rod 17 and the fixing column 16. The limiting function can effectively prevent unnecessary displacement of the fixing rod 17 during use, and the sliding connection method makes it easy to adjust the position of the limiting plate 20 during installation.

[0056] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
