[0045] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , an embodiment of the present application provides a mobile energy storage device, comprising a power supply body 100, at least one heat dissipation mechanism 200, a first fan mechanism 300 and a second fan mechanism 400. The heat dissipation mechanism 200 is arranged in the power supply body 100 to achieve heat dissipation through heat exchange with the power supply body 100. The first fan mechanism 300 is arranged on one side of the power supply body 100, and the second fan mechanism 400 is arranged on the other side of the power supply body 100. By arranging the first fan mechanism 300 and the second fan mechanism 400 on the two sides of the power supply body 100, one of the first fan mechanism 300 and the second fan mechanism 400 blows air into the power supply body 100, and the other one of the first fan mechanism 300 and the second fan mechanism 400 draws air out of the power supply body 100 to achieve air flow in the power supply body 100, so that the heat generated by the heat dissipation mechanism 200 due to heat exchange can diffuse out of the power supply body 100 along the air flow, and the cycle is repeated to achieve the purpose of heat dissipation.

[0046] Specifically, the heat dissipation mechanism 200 comprises a first heat dissipation plate 210 and a second heat dissipation plate 220 arranged oppositely, and the first heat dissipation plate 210 and the second heat dissipation plate 220 are arranged at intervals to form an air duct 230 between the first heat dissipation plate 210 and the second heat dissipation plate 220. The air duct 230 serves as a channel for air flow. The first fan mechanism 300 is located at a first end of the air duct 230, and the second fan mechanism 400 is located at a second end of the air duct 230. The first fan mechanism 300 and the second fan mechanism 400 have the same rotation direction, so that when the first fan mechanism 300 and the second fan mechanism 400 work, air flow in the air duct 230 can be formed in a first direction or in a second direction opposite to the first direction.

[0047] In an exemplary embodiment, when the first fan mechanism 300 and the second fan mechanism 400 rotate in a forward direction, air in the air duct 230 flows in the first direction. When the first fan mechanism 300 and the second fan mechanism 400 rotate in the forward direction, air in the air duct 230 flows in the second direction opposite to the first direction.

[0048] The mobile energy storage device in the embodiment is provided with the power supply body 100, at least one heat dissipation mechanism 200, the first fan mechanism 300 and the second fan mechanism 400. The heat dissipation mechanism 200 is arranged in the power supply body 100. The heat dissipation mechanism 200 comprises the oppositely arranged first heat dissipation plate 210 and the second heat dissipation plate 220. The first heat dissipation plate 210 is arranged in the second heat dissipation plate 220 to form the air duct 230 between the first heat dissipation plate 210 and the second heat dissipation plate 220. The first fan mechanism 300 is arranged on one side of the power supply body 100 and corresponds to the first end of the air duct 230. The second fan mechanism 400 is arranged on the other side of the power supply body 100 and corresponds to the second end of the air duct 230. The rotation directions of the first fan mechanism 300 and the second fan mechanism 400 are the same. When the first fan mechanism 300 and the second fan mechanism 400 rotate forward, the air in the air duct 230 flows in the first direction. When the first fan mechanism 300 and the second fan mechanism 400 rotate forward, the air in the air duct 230 flows in the second direction opposite to the first direction. The heat exchange between the heat dissipation plate and the battery occurs. The rotation directions of the first fan mechanism 300 and the second fan mechanism 400 are the same when they work. One fan mechanism is used to guide the air and the other fan mechanism is used to blow the air to form the one-way and continuous air flow in the air duct 230 in the power supply body 100. The air flow carries the heat when flowing through the heat dissipation plate, which is beneficial to improve the heat dissipation efficiency. The first fan mechanism 300 and the second fan mechanism 400 can rotate in both directions, which is beneficial to the bidirectional heat dissipation and further improves the heat dissipation effect.

[0049] In one embodiment, the power supply body 100 comprises the energy storage battery 110, the battery compartment 120 and the cover plate 130. The inside of the battery compartment 120 is formed with the mounting cavity 121 with one end opening. The energy storage battery 110 and the heat dissipation mechanism 200 are assembled in the mounting cavity 121 to dissipate heat through the heat dissipation mechanism 200. The cover plate 130 is detachably mounted on the battery compartment 120 and blocks the opening of the mounting cavity 121 to isolate the mounting cavity 121 from the external space, thereby playing a protective role for the energy storage battery 110 in the battery compartment 120. At the same time, the cover plate 130 is detachably arranged to open the battery compartment 120 to repair, replace and maintain the energy storage battery 110 inside when repairing or maintaining. The first fan mechanism 300 is embedded on one side of the battery compartment 120 and the second fan mechanism 400 is embedded on the other side of the battery compartment 120.

[0050] The energy storage battery 110 is in contact with the heat dissipation mechanism 200, so that the heat dissipation mechanism 200 can transfer the heat generated by the energy storage battery 110 through heat exchange between the energy storage battery 110 and the heat dissipation mechanism 200, thereby achieving heat dissipation of the energy storage battery 110. Specifically, the energy storage battery 110 is in contact with the side of the first heat dissipation plate 210 and / or the second heat dissipation plate 220 away from the air duct 230, so that the heat of the energy storage battery 110 can be exchanged through the contact between the energy storage battery 110 and the first heat dissipation plate 210 and / or the second heat dissipation plate 220, and the heat is transferred to the first heat dissipation plate 210 and / or the second heat dissipation plate 220 in contact, and then the heat is exchanged again through the contact between the first heat dissipation plate 210 and / or the second heat dissipation plate 220 and the air in the air duct 230 to transfer the heat to the air in the air duct 230, and the heat is carried out of the power supply body 100 along with the flow of the air in the air duct 230, thereby achieving heat dissipation.

[0051] In an optional embodiment, the power supply body 100 further comprises a power supply panel 140 embedded on the battery compartment 120, and a display module 141 and a power supply interface 142 are mounted on the power supply panel 140. The display module 141 can be a display screen, a touch screen with display function, etc., for displaying data such as power, internal temperature and air volume. The power supply interface 142 can be a power socket, a data interface, etc. The power socket can be divided into a power supply socket and a charging socket, and the power supply socket and the data interface are used to supply power to external devices, and the charging socket is used to charge the energy storage battery 110. In specific implementation, multiple groups of power supply interfaces 142 can be provided according to actual needs.

[0052] In an optional embodiment, the bottom of the battery compartment 120 is further provided with a roller 150 to facilitate the movement of the entire power supply body 100. The roller 150 can be a universal wheel with a self-locking function to improve the flexibility and stability of the movement of the power supply body 100.

[0053] In an embodiment, a plurality of heat dissipation mechanisms 200 are provided in the power supply body 100, and the plurality of heat dissipation mechanisms 200 are arranged at intervals to form an installation space 240 for installing the energy storage battery 110 between two adjacent heat dissipation mechanisms 200, and the size of the installation space 240 is adapted to the size of the energy storage battery 110, so that the energy storage battery 110 can be in contact with the heat dissipation mechanism 200 after installation.

[0054] Each heat dissipation mechanism 200 is provided with a first heat dissipation plate 210 and a second heat dissipation plate 220; the side of the first heat dissipation plate 210 facing the air duct 230 is provided with a plurality of first fins 211, and the side of the second heat dissipation plate 220 facing the air duct 230 is provided with a plurality of second fins 221. In the embodiment, the first fins 211 and the second fins 221 are oppositely arranged, and the first fins 211 and the second fins 221 extend into the air duct 230 to play a certain blocking role on the air flowing through the air duct 230, so as to reduce the air flow rate, ensure the air to fully contact with each heat dissipation plate and fin, and further improve the heat dissipation effect. It can be understood that, in some other embodiments, the first fins 211 and the second fins 221 can also be staggered, and the projection parts of the first fins 211 and the second fins 221 on the plane perpendicular to the air flow direction overlap, so that the flow path of the air in the air duct 230 is S-shaped, so as to prolong the flow path of the air, further reduce the flow rate of the air, and make the air more fully contact with each heat dissipation plate and fin, so as to further improve the heat dissipation effect.

[0055] In an optional embodiment, the materials of the first heat dissipation plate 210, the second heat dissipation plate 220, the first fins 211 and the second fins 221 are all copper, so that the first heat dissipation plate 210, the second heat dissipation plate 220, the first fins 211 and the second fins 221 have good heat resistance and corrosion resistance, which is conducive to faster heat dissipation to the external environment.

[0056] In an embodiment, referring to Figure 4 and Figure 5 , the first fan mechanism 300 includes a first housing 310, a first fan 320, a first filter screen 330 and a first mounting plate 340.

[0057] The first shell 310 is embedded on one side of the power supply body 100, and the power supply body 100 is provided with a first clamping groove 122 at a position corresponding to the first shell 310. The first shell 310 is embedded in the first clamping groove 122. For example, the first clamping groove 122 includes a first outer groove section 122a with a smaller size, a first inner groove section 122b with a larger size, and a first tapered section 122c connecting the first outer groove section 122a and the first inner groove section 122b. The first outer groove section 122a is located at the outer end of the first clamping groove 122, that is, the end close to the outside of the power supply body 100. The first inner groove section 122b is located at the inner end of the first clamping groove 122, that is, the end close to the inside of the power supply body 100. In this way, the first shell 310 can be stably assembled on the power supply body 100, thereby improving the overall installation stability of the first fan mechanism 300. It can be understood that in other embodiments, only the first outer groove section 122a and the first inner groove section 122b can be provided, or the sizes of the first outer groove section 122a and the first inner groove section 122b can be set to be the same size and the first shell 310 can be fixed by buckling, bolting or other methods. The outer wall of the first shell 310 is adapted to the outer wall of the first clamping groove 122, and after the first shell 310 is embedded in place, the outer wall of the first shell 310 is attached to the groove wall of the first clamping groove 122, so as to prevent air from flowing out of the gap between the first shell 310 and the first clamping groove 122, thereby improving the air inlet and outlet efficiency.

[0058] The inner end of the first shell 310 is provided with a first ventilation groove 311 in communication with the first end of the air duct 230. The size of the first ventilation groove 311 is adapted to the size of the air duct 230 or the size of the first ventilation groove 311 is greater than the size of the air duct 230, so as to ensure the flow of air when entering and exiting the air duct 230, thereby ensuring the heat dissipation efficiency. It can be understood that in other embodiments, according to the heat dissipation requirement of the power supply body 100, the size of the first ventilation groove 311 can also be smaller than the size of the air duct 230 to adapt to different heat dissipation requirements.

[0059] The outer end of the first shell 310 is provided with a first mounting port 312. The first mounting port 312 is provided on the inner wall of the first shell 310 at a position corresponding to the first outer groove section 122a. The first fan 320 is mounted on the inner wall of the first mounting port 312. The first fan 320 is located closer to the outside of the power supply body 100, so that there is a certain distance between the first fan 320 and the air duct 230 or the first ventilation groove 311. When the first fan 320 blows air, it is beneficial to the efficient entry of external air into the power supply body 100. When the first fan 320 draws air, it is beneficial to the sufficient outflow of air in the power supply body 100. The first fan 320 is detachably mounted on the inner wall of the first mounting port 312, so as to facilitate the disassembly, maintenance and the like of the first fan 320.

[0060] The first mounting plate 340 is detachably connected to the outer end of the first housing 310. Specifically, the first mounting plate 340 covers the outer wall of the power supply body 100 at a position corresponding to the first clamping slot 122. The first mounting plate 340 is in contact with the outer end of the first housing 310 and is connected to the first housing 310 by buckling or screwing. The first mounting plate 340 fixes the first housing 310 and can be detached from the first housing 310 when maintenance is required.

[0061] The first filter screen 330 is detachably mounted on the side of the first mounting plate 340 facing the first fan 320, i.e., the first filter screen 330 is arranged between the first mounting plate 340 and the first fan 320. The first filter screen 330 is used to filter dust and impurities in the air to prevent dust and impurities from entering the inside of the power supply body 100 and causing damage to the power supply body 100. Specifically, the first filter screen 330 can filter dust and impurities in the air and adsorb them on the outer side of the first filter screen 330. When the air flows in the first direction, the air flows through the first filter screen 330 from the outside to the inside, so that the outer side of the first filter screen 330 can block and accumulate dust and impurities, preventing dust and impurities from entering the inside of the power supply body 100. When the air flows in the second direction, the air flows through the first filter screen 330 from the inside to the outside, so that the dust and impurities accumulated on the outer side of the first filter screen 330 are blown off to clean the first filter screen 330.

[0062] The first mounting plate 340 is detachably connected to the outer end of the first housing 310. Specifically, the first mounting plate 340 covers the outer wall of the power supply body 100 at a position corresponding to the first clamping slot 122. The first mounting plate 340 is in contact with the outer end of the first housing 310 and is connected to the first housing 310 by buckling or screwing. The first mounting plate 340 fixes the first housing 310 and can be detached from the first housing 310 when maintenance is required.

[0063] In an alternative embodiment, please refer to Figure 6 and Figure 7The first arc-shaped baffle 342 is arranged at a position corresponding to the first air outlet 341 on the first mounting plate 340, and an end of the first arc-shaped baffle 342 away from the first mounting plate 340 is spaced apart from the first mounting plate 340 to form a first auxiliary air outlet 343. The first auxiliary air outlet 343 is arranged at an angle with the first air outlet 341. Since hot air is lighter than cold air, the hot air will naturally rise. The first auxiliary air outlet 343 is arranged at an angle with the first air outlet 341, so that the first auxiliary air outlet 343 faces downward, which can change the flow direction of the air sucked or blown by the first fan 320, so as to suck more cold air and further improve the heat dissipation efficiency. In addition, when the dust and impurities in the air are sucked in, the first arc-shaped baffle 342 can block the dust and impurities, so as to reduce the accumulation of dust and impurities on the first filter screen 330. When the dust and impurities on the first filter screen 330 are blown off, the first arc-shaped baffle 342 can also block the blown-off dust and impurities, so as to prevent the dust and impurities from being blown into the external air.

[0064] In one embodiment, please refer to Figure 8 The second fan mechanism 400 includes a second housing 410, a second fan 420, a second filter screen 430, and a second mounting plate 440.

[0065] The second housing 410 is embedded on the other side of the power supply body 100. The power supply body 100 is provided with a second clamping groove 123 at a position corresponding to the second housing 410. The second housing 410 is embedded in the second clamping groove 123. For example, the second clamping groove 123 includes a second outer groove segment 123a with a smaller size, a second inner groove segment 123b with a larger size, and a second tapered segment 123c connecting the second outer groove segment 123a and the second inner groove segment 123b. The second outer groove segment 123a is located at the outer end of the second clamping groove 123, i.e., the end close to the outside of the power supply body 100. The second inner groove segment 123b is located at the inner end of the second clamping groove 123, i.e., the end close to the inside of the power supply body 100. In this way, the second housing 410 can be stably assembled on the power supply body 100, so as to improve the overall installation stability of the second fan mechanism 400. It can be understood that in other embodiments, only the second outer groove segment 123a and the second inner groove segment 123b can be provided, or the sizes of the second outer groove segment 123a and the second inner groove segment 123b can be set to be the same, and the second housing 410 can be fixed by buckling, bolting, or other methods. The outer wall of the second housing 410 is adapted to the outer wall of the second clamping groove 123, and after the second housing 410 is embedded in place, the outer wall of the second housing 410 is attached to the groove wall of the second clamping groove 123, so as to prevent air from flowing out from the gap between the second housing 410 and the second clamping groove 123, thereby improving the air inlet and outlet efficiency.

[0066] The inner end of the second shell 410 is provided with a second air vent 411 in communication with the second end of the air duct 230, the size of the second air vent 411 is matched with the size of the air duct 230 or the size of the second air vent 411 is larger than the size of the air duct 230, so as to ensure the air flow when entering and leaving the air duct 230, thereby ensuring the heat dissipation efficiency; it can be understood that in other embodiments, according to the heat dissipation requirement of the power supply body 100, the size of the second air vent 411 can also be smaller than the size of the air duct 230, so as to adapt to different heat dissipation requirements.

[0067] The outer end of the second shell 410 is provided with a second mounting port 412, the second mounting port 412 is arranged on the inner wall of the second shell 410 at the position corresponding to the second air groove segment 123a, and the second fan 420 is mounted on the inner wall of the second mounting port 412. The position of the second fan 420 is closer to the outside of the power supply body 100, so that there is a certain distance between the second fan 420 and the air duct 230 or the second air vent 411. When the second fan 420 blows air, it is beneficial to the efficient entry of external air into the power supply body 100, and when the second fan 420 draws air, it is beneficial to the sufficient outflow of air in the power supply body 100. The second fan 420 is detachably mounted on the inner wall of the second mounting port 412, so as to facilitate the disassembly, maintenance and the like of the second fan 420.

[0068] The second mounting plate 440 is detachably connected with the outer end of the second shell 410. Specifically, the second mounting plate 440 covers the position of the outer wall of the power supply body 100 corresponding to the second clamping groove 123, the second mounting plate 440 is in contact with the outer end of the second shell 410, and is connected with the second shell 410 through buckling or bolts, so as to fix the second shell 410, and when maintenance is required, the second shell 410 can be detached.

[0069] The second filter screen 430 is detachably mounted on the side of the second mounting plate 440 facing the second fan 420; that is, the second filter screen 430 is arranged between the second mounting plate 440 and the second fan 420. The second filter screen 430 is used for filtering dust and impurities in the air, so as to avoid damage to the power supply body 100 caused by dust and impurities entering the inside of the power supply body 100. Specifically, the second filter screen 430 can filter dust and impurities in the air and be adsorbed on the outer side of the second filter screen 430. When the air flows in the first direction, the air flows through the second filter screen 430 from the outside to the inside, so that the outer side of the second filter screen 430 can block and accumulate dust and impurities, preventing dust and impurities from entering the inside of the power supply body 100; when the air flows in the second direction, the air flows through the second filter screen 430 from the inside to the outside, so that the dust and impurities accumulated on the outer side of the second filter screen 430 are blown off, so as to achieve the purpose of cleaning the second filter screen 430.

[0070] A plurality of second air outlets 441 are arranged on the second mounting plate 440 and face away from the second air blower 420. The plurality of second air outlets 441 are in communication with the second end of the air duct 230 through the second air vent groove 411.

[0071] In an alternative embodiment, referring to Figure 9 Similarly to the first mounting plate 340, the second mounting plate 440 is provided with a second arc-shaped baffle 442 at a position corresponding to the second air outlet 441. An end of the second arc-shaped baffle 442 away from the second mounting plate 440 is spaced apart from the second mounting plate 440 to form a second auxiliary air outlet 443. The second auxiliary air outlet 443 is arranged at an angle with the second air outlet 441. Similarly to the first auxiliary air outlet 343, the second auxiliary air outlet 443 is arranged at an angle with the second air outlet 441 so that the second auxiliary air outlet 443 faces downward. This can change the flow direction of the air sucked in or blown out by the second air blower 420, which is conducive to sucking in more cold air and further improving the heat dissipation efficiency. In addition, the second auxiliary air outlet 443 faces downward. When dust and impurities in the air are sucked in, the second arc-shaped baffle 442 can block the dust and impurities, thereby reducing the accumulation of dust and impurities on the second filter screen 430. When the dust and impurities on the second filter screen 430 are blown off, the second arc-shaped baffle 442 can also block the blown-off dust and impurities to prevent the dust and impurities from being blown into the external air.

[0072] Specifically, when the first fan 320 and the second fan 420 are both rotating forward, the first fan 320 functions as a blower to blow cold air into the power body 100, at this time, the cold air flows into the air duct 230 from the first end of the air duct 230 along the first direction in sequence through the first auxiliary air port 343, the first air port 341, the first shell 310, the first ventilation slot 311, and the cold air exchanges heat with the first heat sink 210 and the second heat sink 220 to be heated up and form hot air opposite to the cold air, the second fan 420 functions as an inducer to induce the hot air in the air duct 230 out of the power body 100, at this time, the hot air flows out of the air duct 230 from the second end of the air duct 230 along the first direction in sequence through the second ventilation slot 411, the second shell 410, the second air port 441 and the second auxiliary air port 443, and the cycle is repeated to realize continuous and efficient heat dissipation of the energy storage battery 110. When the first fan 320 and the second fan 420 are both rotating reversely, the second fan 420 functions as a blower to blow cold air into the power body 100, at this time, the cold air flows into the air duct 230 from the second end of the air duct 230 along the second direction in sequence through the second auxiliary air port 443, the second air port 441, the second shell 410, the second ventilation slot 411, and the cold air exchanges heat with the first heat sink 210 and the second heat sink 220 to be heated up and form hot air opposite to the cold air, the first fan 320 functions as an inducer to induce the hot air in the air duct 230 out of the power body 100, at this time, the hot air flows out of the air duct 230 from the first end of the air duct 230 along the second direction in sequence through the first ventilation slot 311, the first shell 310, the first air port 341 and the first auxiliary air port 343, and the cycle is repeated to realize continuous and efficient heat dissipation of the energy storage battery 110.

The control module 520 is used to control the first fan mechanism 300 and the second fan mechanism 400 to rotate forward synchronously and rotate reversely synchronously according to the real-time air volume.

[0074] In an exemplary embodiment, the air volume measuring module 510 is installed on the inner wall of the first housing 310 and / or the second housing 410, for monitoring the air volume entering and exiting the power supply body 100 in real time, so that when the real-time air volume is lower than the preset threshold, the first fan 320 and the second fan 420 are controlled by the control module 520 to rotate reversely synchronously, so as to blow off the dust and impurities accumulated on the first filter screen 330 and the second filter screen 430; after the first fan 320 and the second fan 420 rotate reversely, the air volume measuring module 510 continues to monitor the real-time air volume, and if the real-time air volume is still lower than the preset threshold, the user can be prompted to replace or clean the filter screen in time by using the sound and / or photoelectric alarm.

[0075] In an optional embodiment, the mobile energy storage device further comprises a temperature sensing module 530, which is arranged inside the power supply body 100 and corresponds to the position of the air duct 230, and is electrically connected with the control module 520, for monitoring the temperature inside the power supply body 100 in real time and displaying the temperature by the display module 141, so that the user can know the real-time state of the mobile energy storage device, and thus ensure the safe use of the mobile energy storage device.
