Description

Technical Field

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

[0002] Energy storage power supplies can store electricity and provide power to electrical appliances during power outages or when the user is away.

[0003] Currently, with the development of camping culture, the public's demand for outdoor energy storage power supplies is increasing, and there are more and more types of energy storage power supplies, which have advantages such as being easy to carry, having a variety of interfaces, and having large battery capacity.

[0004] However, most large-capacity energy storage power supplies suffer from high heat generation, meaning they have poor heat dissipation. To dissipate heat, they need to open a large number of ventilation holes to increase the cooling effect of the fan. However, opening too many ventilation holes will exacerbate the entry of dust, thereby creating safety hazards for the external circuitry of the product and reducing the lifespan of the energy storage power supply. Summary of the Invention

[0005] The purpose of this invention is to provide a portable energy storage power source to solve at least one technical problem existing in the prior art.

[0008] A heat-conducting core is fixed inside the ventilation duct, and the heat-conducting core is connected to the heat source inside the heat dissipation shell;

[0009] A heat dissipation shell is installed on the outer wall of the circular block and can rotate intermittently 180 degrees. Both sides of the outer wall of the heat dissipation shell are provided with through grooves, and filters are installed in both through grooves.

[0015] Preferably, the actuating component includes a fan-shaped groove formed on the plane of the circular block, and the fan-shaped groove is connected to the arc-shaped groove. The side wall of the arc panel is integrally formed with a fan-shaped plate. The fan-shaped plate is rotatably installed in the fan-shaped groove and rotates around the center of the circular block. A swing rod is also rotatably installed at the center of the circular block. The outer wall of the swing rod is fixed with a mounting rod, and the mounting rod is connected to the outer wall of the fan-shaped plate with a second tension spring.

[0016] The actuation assembly also includes two stop buttons fixed to the outer wall of the circular block, and the stop buttons are used to prevent the swing arm from contacting the sector plate.

[0017] The actuating assembly also includes two levers fixed to the inner wall of the heat dissipation housing. When the heat dissipation housing rotates, one of the levers will contact and actuate the mounting rod to rotate. When the heat dissipation housing stops rotating, the mounting rod will drive the swing arm to rotate past the diameter line where the second tension spring and the sector plate are connected.

[0018] Preferably, the drive assembly includes a hole formed on the outer wall of the circular block and communicating with the mounting cavity, and a wedge block is slidably connected in the hole.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Example 1;

[0042] Please see Figures 1 to 11 The present invention provides a technical solution: a portable energy storage power supply, including a power supply body 1 and a support for supporting it, and further including:

[0043] A circular block 4 is fixed to the side wall of the power supply body 1. A ventilation channel 5 is provided inside the circular block 4, which runs through the diameter. A cooling fan 6 is installed inside the ventilation channel 5.

[0044] The heat-conducting core 7 is fixed inside the ventilation duct 5 and is connected to the heat source inside the heat dissipation shell 2;

[0045] The heat dissipation shell 2 is installed on the outer wall of the circular block 4 and can rotate intermittently 180 degrees. Both sides of the outer wall of the heat dissipation shell 2 are provided with through grooves, and each of the two through grooves is equipped with a filter screen 3. The two filter screens 3 are located at the two outlet positions of the ventilation duct 5 respectively.

[0046] When in use, this portable energy storage power supply can be carried, moved and supported using a bracket. The specific bracket structure is not shown in the diagram, but can be implemented by those skilled in the art, so it will not be described in detail here.

[0047] When the energy storage power supply is connected to power, the heat generated in the power supply body 1 is conducted to the ventilation duct 5 by the heat conduction of the heat conduction core 7, and the heat is carried out with the air flow, thereby improving the heat dissipation effect of the power supply body 1. At the same time, the heat dissipation effect is improved by starting the cooling fan 6 and increasing the air flow rate.

[0048] The filter screen 3 filters out dust and other impurities in the outdoor air, preventing them from entering the ventilation duct 5, reducing safety hazards and improving the service life of the energy storage power supply.

[0049] Furthermore, during the heat dissipation process, driven by the external mechanism, the heat dissipation shell 2 rotates intermittently 180 degrees. The purpose of this is to change the position of the two filters 3. Since the airflow direction of the cooling fan 6 is fixed, by changing the position of the two filters 3, the dust and other impurities filtered on the filters 3 can be blown off by the airflow from the inside out. By intermittently changing the position of the two filters 3, the effect of alternating self-cleaning of the two filters 3 can be achieved. This can prevent dust from entering and at the same time ensure the filtering effect of the filters 3, so as to ensure the heat dissipation effect of the power supply body 1.

[0050] The specific driving method for the heat dissipation shell 2 can be a motor or other means, which can be powered by the power supply body 1.

[0051] In one preferred embodiment, a cleaning assembly for cleaning dust inside the filter mesh 3 is also included, and two sets of cleaning assemblies are provided, respectively disposed on both sides of the ventilation duct 5.

[0052] The cleaning assembly includes a mounting cavity 8 formed on the outer wall of the arc surface of the circular block 4, a sliding plate 9 slidably mounted on the inner wall of the mounting cavity 8, a first tension spring 10 connecting the sliding plate 9 and the inner wall of the mounting cavity 8, and brush bristles mounted on the outer wall of the sliding plate 9 away from the first tension spring 10.

[0053] The cleaning assembly also includes a drive assembly for driving the slide plate 9 to slide back and forth within the mounting cavity 8.

[0054] During the process of the heat dissipation shell 2 rotating to switch between the two filters 3, when the filter 3 rotates to the mounting cavity 8, the slide plate 9 slides back and forth in the mounting cavity 8 under the drive of the drive component, and the bristles on it are inserted into the filter holes of the filter 3 from the inside to the outside, pushing the impurities outward and clearing the filter holes. At the same time, the impurities or dust pushed out are also in a loose state, so that when they rotate to the ventilation duct 5, they can fall off more easily under the action of the wind, further improving the cleaning effect of the filter 3.

[0055] By setting up two sets of cleaning components, the cleaning process of the two filters 3 can be performed separately as the heat sink housing 2 reciprocates. See details below. Figure 3 .

[0056] In one preferred embodiment, an arc-shaped groove 15 is provided on the outer wall of the circular block 4 located at the air outlet of the ventilation duct 5, and an arc panel 14 is slidably installed on the inner wall of the arc groove 15. A through hole groove 21 is provided on the outer wall in the middle of the arc panel 14, and the arc length of the arc panel 14 is at least three times the arc length at the outlet of the ventilation duct 5.

[0057] The outer wall of the circular block 4 is also equipped with a toggle assembly for driving the arc panel 14 to swing back and forth, and the swinging of the arc panel 14 begins after the heat sink housing 2 has finished rotating.

[0058] As we know from the previous content, when the heat sink 2 rotates, the cleaning component can be used to poke out the dust and impurities in the filter screen 3 and loosen it. Then, after the heat sink 2 rotates 180 degrees to complete the switching.

[0059] At this point, the toggle component causes the curved panel 14 to begin swinging. (See details below.) Figure 3 That is, the arc panel 14 starts to rotate counterclockwise. Since the arc length of the arc panel 14 is at least three times the arc length of the outlet of the ventilation duct 5, the arc panel 14 will first seal the outlet of the ventilation duct 5. Then, as the arc panel 14 rotates, the air outlet changes to air outlet through the through hole groove 21. By reducing the size of the air outlet, the air flow rate is increased. As the arc panel 14 rotates, the through hole groove 21 will sweep the filter screen 3 from the edge. The high-speed airflow sweeps the filter screen 3 from the inside to the outside, thereby improving the cleaning effect of the filter screen 3. Since the cleaning component previously pushed out the impurities in the filter holes and made them loose, it is easier to deal with the loose dust during sweeping, further improving the cleaning effect of the filter screen 3.

[0060] In one preferred embodiment, the actuating component includes a fan-shaped groove 13 formed on the plane of the circular block 4, and the fan-shaped groove 13 is connected to the arc-shaped groove 15. The side wall of the arc panel 14 is integrally formed with a fan-shaped plate 22. The fan-shaped plate 22 is rotatably installed in the fan-shaped groove 13 and rotates around the center of the circular block 4. A swing rod 16 is also rotatably installed at the center of the circular block 4. An installation rod 18 is fixed to the outer wall of the swing rod 16, and a second tension spring 19 is connected to the outer wall of the fan-shaped plate 22.

[0061] The toggle assembly also includes two stop buttons 17 fixed to the outer wall of the circular block 4, and the stop buttons 17 are used to prevent the swing arm 16 from contacting the sector plate 22.

[0062] The actuation assembly also includes two toggle blocks 20 fixed to the inner wall of the heat sink housing 2. When the heat sink housing 2 rotates, one of the toggle blocks 20 will contact and actuate the mounting rod 18 to rotate. When the heat sink housing 2 stops rotating, the mounting rod 18 will drive the swing arm 16 to rotate past the diameter line where the second tension spring 19 and the sector plate 22 are connected.

[0063] For an example of how to implement the toggle assembly, please refer to [link / reference]. Figure 6-8 ,in Figure 6 This is the initial state before the heat sink housing 2 rotates. When the heat sink housing 2 rotates, the lever 20 fixed to its inner wall will swing the mounting rod 18 to rotate, thereby driving the swing rod 16 to rotate. At the same time, the second tension spring 19 is stretched until the swing rod 16 rotates to... Figure 6 When the position marked 'a' is reached, the direction of the tension of the second tension spring 19 is collinear with that of the swing rod 16. That is, the connection point between the second tension spring 19 and the sector plate 22, the connection point between the sector plate 22 and the sector groove 13, and the mounting rod 18 are all on the same straight line. Then, when the heat dissipation shell 2 stops rotating, the mounting rod 18 drives the swing rod 16 to cross this line. At this time, the second tension spring 19 will apply a reverse tangential force to the sector plate 22, thereby causing the sector plate 22 to start rotating to complete the process of the through hole groove 21 sweeping the filter screen 3.

[0064] It is worth noting that before the three points are aligned on the same straight line, the tangential component of the force exerted by the second tension spring 19 on the sector plate 22 will keep the sector plate 22 in a stationary state.

[0065] The purpose of this is to allow the filter screen 3 to rotate only after the heat dissipation shell 2 has stopped rotating, thus creating a sequential order between the two. This prevents the filter screen 3 from rotating simultaneously with the fan-shaped plate 22, which would result in insufficient cleaning of the filter screen 3 and improve the cleaning effect of the filter screen 3.

[0066] Similarly, when the heat sink 2 rotates in the opposite direction, another lever 20 will drive the mounting rod 18 to rotate, so it will not be described in detail. In this way, the heat sink 2 can drive the fan-shaped plate 22 to rotate back and forth.

[0067] In one preferred embodiment, the drive assembly includes a hole formed on the outer wall of the circular block 4 and communicating with the mounting cavity 8, and a wedge 11 is slidably connected in the hole. The end of the wedge 11 that extends into the mounting cavity 8 is formed as an inclined surface, and the inclined surface contacts and abuts against the sliding plate 9.

[0068] The drive assembly also includes multiple extrusion protrusions 12 fixed to the inner wall of the heat sink housing 2, and the extrusion protrusions 12 are spaced apart. When the heat sink housing 2 rotates, the multiple extrusion protrusions 12 alternately contact and extrude the wedge block 11.

[0069] In summary, when the heat dissipation housing 2 rotates, it will cause the internal pressing protrusion 12 to rotate as well. The pressing protrusion 12 will alternately contact and press the wedge 11. Under the action of pressing, the wedge 11 will slide into the mounting cavity 8. Under the action of its inclined surface, it will push the slide plate 9 to move. Then, when the pressing protrusion 12 separates from the wedge 11, the slide plate 9 will return to its original position under the action of the first tension spring 10. At the same time, the wedge 11 will also return to its original position. In this way, as the pressing protrusion 12 alternately presses the wedge 11, the slide plate 9 can be driven to slide back and forth continuously, thereby using the bristles on it to clean the filter screen 3.

[0070] In one preferred embodiment, the extrusion bumps 12 are distributed on the heat dissipation housing 2 near the filter screen 3.

[0071] By setting the position of the pressing protrusion 12, the slide plate 9 can only start moving when the filter screen 3 rotates to the mounting cavity 8. This can prevent the bristles on the slide plate 9 from bending due to prolonged pressure on the inner wall of the heat dissipation shell 2 during movement, thus affecting the cleaning effect on the filter screen 3.

[0072] In one preferred embodiment, the heat-conducting core 7 is made of copper, and one end of the heat-conducting core 7 inserted into the ventilation duct 5 is flat.

[0073] The copper core can improve the heat conduction effect, thereby improving the heat dissipation effect of the power supply body 1, while the flat shape can increase its heat exchange area with the air.

[0074] In one preferred embodiment, the external shape of the heat dissipation shell 2 is the same as the external shape of the power supply body 1, and the planes are flush.

[0075] Example 2 is basically the same as Example 1, except that it provides a second implementation method for the driving component. See details below. Figure 12 ;

[0076] In one preferred embodiment, the drive assembly includes an inflatable airbag 23 mounted between the slide plate 9 and the inner wall of the mounting cavity 8, and the inflatable airbag 23 is connected to an external inflation pump assembly.

[0077] An external air pump assembly can intermittently inflate the airbag 23, thereby using its expansion and contraction to drive the slide plate 9 to move back and forth, and the inflation and deflation time can also be easily set.

[0078] In Example 3, based on Example 1 or Example 2, two sets of the above structure are provided, and they are respectively located on both sides of the power supply body 1. For details, please refer to... Figure 13 This not only improves heat dissipation efficiency, but also makes the local heat dissipation of the power supply body 1 more uniform.

[0079] The standard parts used in this embodiment can be purchased directly from the market, while the non-standard structural parts described in the specification and drawings can be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0080] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
