Description

Technical Field

[0001] The present application relates to the technical field of energy storage devices, and more specifically, to an energy storage power supply. Background Art

[0002] Energy storage power supplies usually include battery cells, brackets and shells. During assembly, the battery cells are placed in the brackets to form a battery pack, which is then screwed into the shell to form an energy storage power supply. However, the screw locking process is inefficient, and due to the heavy weight of the battery pack, a large number of screws are required, which further reduces efficiency and increases component costs. Summary of the invention

[0003] The embodiments of the present application provide an energy storage power supply to solve at least one of the above-mentioned technical problems.

[0004] The energy storage power supply of the embodiment of the present application includes:

[0005] A battery pack, wherein first locking columns are provided on both sides of the battery pack along a first direction;

[0006] A housing, wherein at least two slide grooves are formed on the inner wall of the housing in the first direction, and the first locking column is slidably disposed in the slide grooves so that the battery pack is slidably connected to the housing;

[0007] A fixing structure is provided, wherein the fixing structure fixes the first locking column in the slide slot so that the battery pack is fixed in the housing.

[0008] The energy storage power supply proposed in the present application locks the first locking column through the cooperation of the slide groove and the fixing structure to fix the battery pack in the shell. During the process, there is no need to lock a large number of screws, which is beneficial to improving the assembly efficiency of the energy storage power supply. At the same time, it reduces the number of screws used and is also beneficial to reducing the component cost of the energy storage power supply.

[0009] In some embodiments, the battery pack is provided with second locking columns on both sides along the first direction, and a limiting groove is also formed on the inner surface of the shell. The second locking column is configured so that when the battery pack is installed in the shell, the second locking column is inserted into the limiting groove.

[0010] In this way, the second locking column is provided to further fix the battery pack, which is conducive to fixing the battery pack more firmly.

[0011] In some embodiments, the first locking post and the second locking post are spaced apart along the second direction.

[0012] In this way, the first locking column and the second locking column are arranged at intervals along the second direction so that the force on the battery pack can be more uniform, which is beneficial to improving the service life of the battery pack.

[0013] In some embodiments, the housing includes a first shell and a second shell, the slide groove is arranged on the inner wall of the first shell, and the fixing structure is arranged on the inner wall of the second shell.

[0014] In this way, the slide groove and the fixing structure are respectively arranged on the first shell and the second shell, which facilitates the assembly of the battery pack.

[0015] In some embodiments, the fixing structure is a limiting column, and the limiting column is configured to, when the second shell is connected to the first shell, be inserted into the slide groove and abut the first locking column to confine the first locking column in the slide groove.

[0016] In this way, the first locking column is restricted in the locking hole by using a limiting column with a simple structure, which is helpful to reduce the difficulty of processing the housing.

[0017] In some embodiments, the battery pack also includes a limit plate, which is arranged at an end of the first locking column away from the battery pack. The inner wall of the outer shell is also formed with an avoidance groove that cooperates with the limit plate. The limit plate is configured so that when the first locking column slides in the slide groove, the limit plate is slidably arranged in the avoidance groove so that the first locking column cannot be pulled out of the slide groove.

[0018] In this way, the limiting plate can restrict the first locking column in the slide slot so that it cannot be pulled out, thereby preventing the first locking column from falling out of the slide slot when the battery pack is vibrated or impacted, thereby preventing the first locking column from falling out of the slide slot and causing hidden dangers.

[0019] In some embodiments, the slide groove is provided with a connected branch, and the branch is formed with a locking hole, and the locking hole is located on one side of the slide groove. When the fixing structure fixes the first locking column in the slide groove, the first locking column is inserted into the locking hole.

[0020] In this way, the locking hole is set on one side of the slide slot. When the first locking column slides along the slide slot to the locking hole, the first locking column can be temporarily stuck in the locking hole to prevent the first locking column from easily sliding out along the slide slot when the energy storage power supply is overturned or hit.

[0021] In some embodiments, the first locking column is an elastic telescopic column, and the first locking column is configured to compress the first locking column so that the first locking column is slidably disposed in the slide groove during the process of the battery pack being loaded into the shell, so that when the battery pack is installed in the shell, the first locking column is reset and inserted into the locking hole to fix the battery pack in the shell.

[0022] In this way, the first locking column is set as a compressible elastic telescopic column. During installation, it only needs to be compressed. After being installed in place, the first locking column will automatically pop out, which is conducive to reducing the difficulty of assembly.

[0023] In some embodiments, the energy storage power supply further includes a fastener, a fixing portion is formed on the battery pack, a fixing hole corresponding to the fixing portion is provided on the outer shell, and the fastener passes through the fixing hole to be threadedly connected with the fixing portion to fix the battery pack in the outer shell.

[0024] In this way, the fastener can assist the first locking column and the locking hole to further fix the battery pack, distribute the pressure of the first locking column and the locking hole, and fix the battery pack more firmly.

[0025] In some embodiments, the housing is provided with supporting feet, and the fixing holes are provided on the supporting feet.

[0026] In this way, the fixing holes are arranged at the supporting feet, and after the battery pack is fixed, the weight can be directly applied to the supporting feet, which is conducive to making the energy storage power supply more stable.

[0042] See also Figure 1 The energy storage power supply 100 of the embodiment of the present application includes a battery pack 10, a shell 20 and a fixing structure 231. The battery pack 10 is provided with first locking columns 11 on both sides along the first direction; the inner wall of the shell 20 in the first direction is formed with at least two slide grooves 221, and the first locking column 11 is slidably arranged in the slide groove 221 so that the battery pack 10 is slidably connected with the shell 20; the fixing structure 231 fixes the first locking column 11 in the slide groove 221, so that the battery pack 10 is fixed in the shell 20.

[0043] The energy storage power supply 100 proposed in the present application locks the first locking column 11 through the cooperation of the slide groove 221 and the fixing structure 231 to fix the battery pack 10 in the housing 20. During the process, a large number of screws do not need to be locked, which is beneficial to improving the assembly efficiency of the energy storage power supply 100. At the same time, it reduces the number of screws used and is also beneficial to reducing the component cost of the energy storage power supply 100.

[0044] For details, please refer to Figure 1 and Figure 2The energy storage power supply 100 is a device that can store electrical energy and release it when needed. Its main function is to provide a stable and reliable power supply. When the system needs to store electrical energy, the controller will charge the battery pack, and the battery pack will convert the electrical energy into chemical energy for storage; when the system needs to use electrical energy, the controller will first convert the DC energy stored in the battery pack into AC energy, and then output it.

[0045] In the embodiment of the present application, a receiving cavity is formed in the housing 20, and the battery pack 10 is disposed in the receiving cavity.

[0046] In the embodiment of the present application, a handle is provided on the top of the shell 20. The handle is made of metal, specifically, aluminum alloy, and the interior is hollowed out, which is beneficial to the lightweight of the energy storage power supply 100. The strength and durability of the aluminum alloy handle are relatively high, which is beneficial to increase the reliability of the handle and extend the service life of the handle.

[0047] In other embodiments, the handle may also be made of other materials, which may be specifically configured according to actual needs and is not limited here.

[0048] In other embodiments, the handle may also be configured as a flexible handle, which has good adaptability and flexibility, and has better comfort and touch.

[0049] The battery pack 10 includes a plurality of battery cells and a bracket for fixing the plurality of battery cells, the bracket includes a first bracket 12 and a second bracket 13. When the first bracket 12 is connected to the second bracket 13, a cavity for fixing the plurality of battery cells is enclosed between the first bracket 12 and the second bracket 13. The plurality of battery cells are arranged in an upright array in the cavity, that is, the length direction of the battery cells is arranged along the vertical direction to ensure that the space occupied is minimized.

[0050] In other embodiments, the plurality of battery cells may also be arranged in arrays along other directions according to actual needs.

[0051] Furthermore, the battery pack 10 is installed on one side of the housing 20 close to the bottom, which helps to lower the center of gravity of the energy storage power supply 100 and make the energy storage power supply 100 more stable when placed.

[0052] In the embodiment of the present application, the shape of the battery pack 10 is approximately a rectangular parallelepiped, and the first locking column 11 is arranged on the outer surface of the battery pack 10 bracket. Furthermore, the first locking column 11 extends outward from the outer surface of the battery pack 10 bracket in a straight line and is perpendicular to the surface where the first locking column 11 is located.

[0053] In the embodiment of the present application, a first side plate 222 and a second side plate 223 are provided in the outer shell 20. When the battery pack 10 is installed in the outer shell 20, the battery pack 10 is located between the first side plate 222 and the second side plate 223. Furthermore, the width between the first side plate 222 and the second side plate 223 is equal to or slightly larger than the width of the battery pack 10.

[0054] Furthermore, the first locking columns 11 are arranged in pairs, and the two first locking columns 11 arranged in pairs are respectively arranged on two opposite surfaces of the battery pack 10 along a first direction, and the first direction is perpendicular to the first side plate 222 and the second side plate 223. The number of the slide grooves 221 is the same as the number of the first locking columns 11, and the two slide grooves 221 are respectively arranged on the first side plate 222 and the second side plate 223, and are arranged one-to-one with the first locking columns 11.

[0055] The width of the slide slot 221 is slightly greater than the width of the first locking column 11 . When the battery pack 10 is installed in the housing 20 , the first locking column 11 passes through the first side plate 222 and the second side plate of the slide slot 221 .

[0056] In some embodiments, the first locking column 11 may also be disposed inside the housing 20 , and the slide groove 221 may be disposed on the bracket of the battery pack 10 .

[0057] In some embodiments, the number of the first locking posts 11 and the number of the sliding slots 221 may be different, that is, a plurality of first locking posts 11 may be slidably disposed in one sliding slot 221 at the same time.

[0058] See also Figures 1 to 3 In some embodiments, a second locking column 14 is provided on both sides of the battery pack 10 along the first direction, and a limiting groove 232 is also formed on the inner surface of the shell 20. The second locking column 14 is configured so that when the battery pack 10 is installed in the shell 20, the second locking column 14 is inserted into the limiting groove 232.

[0059] In this way, the second locking column 14 further fixes the battery pack 10 , which helps to fix the battery pack 10 more firmly.

[0060] Specifically, in the embodiment of the present application, the number of the second locking columns 14 is two, and the two first locking columns 11 are arranged on two opposite surfaces of the battery pack 10 along the first direction.

[0061] In the embodiment of the present application, there are two limiting grooves 232, both of which are arranged on the second shell 23. When the battery pack 10 is installed in the outer shell 20, the two limiting grooves are respectively located on both sides of the battery pack 10, and the first locking column 11 is clamped in the limiting groove.

[0062] In some embodiments, the first locking post 11 and the second locking post 14 are spaced apart from each other along the second direction.

[0063] In this way, the first locking column 11 and the second locking column 14 are arranged at intervals along the second direction so that the force on the battery pack 10 can be more uniform, which is beneficial to improving the service life of the battery pack 10.

[0064] Specifically, in the embodiment of the present application, the second direction is perpendicular to the first direction and parallel to the horizontal plane. In some embodiments, the second direction may also be perpendicular to the first direction and form an angle of no more than 30° with the horizontal plane.

[0065] See also Figures 3 to 5 In some embodiments, the housing 20 includes a first shell 22 and a second shell 23 , the slide groove 221 is disposed on the inner wall of the first shell 22 , and the fixing structure 231 is disposed on the inner wall of the second shell 23 .

[0066] In this way, the slide groove 221 and the fixing structure 231 are respectively disposed on the first shell 22 and the second shell 23 , so as to facilitate the assembly of the battery pack 10 .

[0067] Specifically, in an embodiment of the present application, the first shell 22 and the second shell 23 are detachably connected, and further, the first shell 22 and the second shell 23 are snap-connected, mortise and tenon connected, or fastener connected. Among them, the fasteners can be selected from bolts, screws, rivets, etc. The selection and installation of fasteners have an important impact on the stability and safety of the connection. The fastener material should have good mechanical properties and chemical stability to adapt to different working environments and load requirements. The selection of fastener size should be calculated and determined based on the size and load requirements of the housing 20 and the bracket. When using fasteners, it is necessary to control the size of the fastening force to ensure the stability and safety of the connection. Excessive fastening force may cause damage or deformation of the connector, while too small a fastening force may result in a loose connection.

[0068] In some embodiments, the connection method between the first shell 22 and the second shell 23 may also be selected to be a non-detachable connection, such as gluing, hot pressing, hot melting, etc.

[0069] In the embodiment of the present application, the first shell 22 and the second shell 23 are both an integral structure formed by integral injection molding. Furthermore, the first side plate 222 and the second side plate 223 are both arranged on the first shell 22. The first side plate 222, the second side plate 223 and the first shell 22 are an integral structure formed by integral processing.

[0070] In other embodiments, the first side plate 222 and the second side plate 223 may both be disposed on the second shell 23 , and the limiting column 231 may be disposed on the first shell 22 .

[0071] In some embodiments, the fixing structure 231 is a limiting column, and the limiting column is configured to be inserted into the slide groove 221 when the second shell 23 is connected to the first shell 22 to limit the first locking column 11 in the locking hole 21.

[0072] In this way, the first locking column 11 is restricted in the locking hole 21 by using a limiting column with a simple structure, which is helpful to reduce the difficulty of processing the housing 20 .

[0073] Specifically, the limiting column 231 and the second shell 23 are also an integrated structure formed by integral processing.

[0074] In some embodiments, when the first shell 22 is connected to the second shell 23, the limiting column 231 is inserted into the slide groove 221 to form a locking space with the slide groove 221 for accommodating and locking the first locking column 11. Furthermore, the outer surface of the limiting column 231 presses against the first locking column 11.

[0075] See also Figure 2 , Figure 4 and Figure 6 In some embodiments, the battery pack 10 further includes a limit plate 111, which is disposed at an end of the first locking column 11 away from the battery pack 10. The inner wall of the housing 20 is further formed with an avoidance groove 224 that cooperates with the limit plate 111. The limit plate 111 is configured such that when the first locking column 11 slides in the slide groove 221, the limit plate 111 is slidably disposed in the avoidance groove 224 so that the first locking column 11 cannot be pulled out of the slide groove 221.

[0076] In this way, the limiting plate 111 can restrict the first locking column 11 in the slide slot 221 so that the first locking column 11 cannot be pulled out, thereby preventing the first locking column 11 from falling out of the slide slot 221 when the battery pack 10 is vibrated or impacted, thereby preventing the first locking column 11 from falling out of the slide slot 221 and causing hidden dangers.

[0077] Specifically, in the embodiment of the present application, the limiting plate 111 is a rounded rectangle, the width of the limiting plate 111 is greater than the width of the slide groove 221, and the width of the limiting plate 111 is also greater than the diameter of the locking hole 21. Further, the width of the avoidance groove 224 is slightly greater than the width of the limiting plate 111, and it is easy to understand that the width of the avoidance groove 224 is also greater than the width of the slide groove 221 and the diameter of the locking hole 21.

[0078] Furthermore, the avoidance groove 224 is also provided on the first side plate 222 and / or the second side plate 223, and is connected with the slide groove 221 to form a T-shaped groove, and the first locking column 11 slides in the T-shaped groove. Furthermore, the locking hole 21 is a blind hole, and the locking hole 21 is also connected with the avoidance groove 224. When the first locking column 11 slides to the locking hole 21, the limit plate 111 is restricted in the avoidance groove 224 and cannot escape from the slide groove 221 or the locking hole 21, so that the first locking column 11 cannot be pulled out from the slide groove 221 or the locking hole 21.

[0079] In some embodiments, the avoidance groove 224 may not be provided. Specifically, taking the locking hole 21 and the slide groove 221 being provided on the first side plate 222 as an example, the locking hole 21 and the slide groove 221 may pass through the first side plate 222, that is, when the first locking column 11 slides in the slide groove 221, the first locking column 11 may extend from the other side of the first side plate 222 through the avoidance groove, and the limiting plate 111 is provided at the end of the first locking column 11 and presses on the surface of the first side plate 222 away from the battery pack 10, so that the first locking column 11 cannot be pulled out of the slide groove 221 or the locking hole 21.

[0080] In some embodiments, the slide groove 221 is provided with a connected branch, and the branch is formed with a locking hole 21. The locking hole 21 is located on one side of the slide groove 221. When the fixing structure 231 fixes the first locking column 11 in the slide groove 221, the first locking column 11 is inserted into the locking hole 21.

[0081] In this way, the locking hole 21 is set on one side of the slide groove 221. When the first locking column 11 slides along the slide groove 221 to the locking hole 21, the first locking column 11 can be temporarily stuck in the locking hole 21 to prevent the first locking column 11 from easily sliding out along the slide groove 221 when the energy storage power supply 100 is overturned or hit.

[0082] Specifically, in the embodiment of the present application, the first shell 22 and the second shell 23 are a left shell and a right shell, the first side plate 222 and the second side plate 223 extend along the width direction of the energy storage power supply 100, the slide groove 221 is arranged along the length direction of the first side plate 222, and the branch is arranged in a direction perpendicular to the slide groove 221.

[0083] Furthermore, the locking hole 21 is arranged on one side of the slide groove 221 close to the bottom of the energy storage power supply 100. In this way, after the battery pack 10 is installed in the first shell 22, if the energy storage power supply 100 needs to be rotated to an upright position, the first locking column 11 will not slide out of the locking hole 21.

[0084] In the embodiment of the present application, the locking hole 21 is arranged near the end of the slide groove 221, so that the sliding length of the first locking column 11 in the slide groove 221 can be extended as much as possible, so that when the energy storage power supply 100 is overturned or hit, it will not easily slide out of the slide groove 221.

[0085] In other embodiments, the locking hole 21 may also be disposed at other locations close to the slide groove 221 , and the specific location of the locking hole 21 may be selected according to actual needs.

[0086] See also Figure 7In some embodiments, the first locking column 11 is an elastic telescopic column, and the first locking column 11 is configured to compress the first locking column 11 so that the first locking column 11 is slidably set in the slide groove 221 during the process of installing the battery pack 10 into the shell 20, so that when the battery pack 10 is installed in the shell 20, the first locking column 11 is reset and inserted into the locking hole 21 to fix the battery pack 10 in the shell 20.

[0087] In this way, the first locking column 11 is configured as a compressible elastic telescopic column. During installation, the first locking column 11 only needs to be compressed. After being installed in place, the first locking column 11 will automatically pop out, which is conducive to reducing the difficulty of assembly.

[0088] Specifically, in some embodiments, the first locking columns 11 can all be configured as elastic telescopic columns, that is, the first locking columns 11 can be compressed to shorten them by pressing or the like. During installation, the battery pack 10 can be installed into the outer shell 20 after all the first locking columns 11 are compressed. When the battery pack 10 is installed in place, the first locking columns 11 will be aligned with the locking holes 21 on the outer shell 20, so that the first locking columns 11 obtain space for expansion, and the compressed first locking columns 11 will be reset immediately, thereby extending into the locking holes 21 to lock the battery pack 10.

[0089] Furthermore, the second locking column 14 may also be configured as an elastic telescopic column.

[0090] It should be noted that the first locking column 11 and the second locking column 14 on the same side of the battery pack 10 should be staggered to avoid the first locking column 11 or the second locking column 14 being inserted into the wrong locking hole 21 during the installation of the battery pack 10, causing the battery pack 10 to be incorrectly fixed, affecting the installation efficiency and making disassembly inconvenient.

[0091] See also Figure 6 and Figure 8 In some embodiments, the energy storage power supply 100 further includes a fastener, a fixing portion 15 is formed on the battery pack 10, and a fixing hole 24 corresponding to the fixing portion 15 is provided on the outer shell 20, and the fastener passes through the fixing hole 24 and is threadedly connected with the fixing portion 15 to fix the battery pack 10 in the outer shell 20.

[0092] In this way, the fastener can assist the first locking column 11 and the locking hole 21 to further fix the battery pack 10, distribute the pressure of the first locking column 11 and the locking hole 21, and fix the battery pack 10 more firmly.

[0093] Specifically, in the embodiment of the present application, four fixing parts 15 are provided on the battery pack 10, and each fixing part 15 is provided with a threaded hole. Correspondingly, four fixing holes 24 are provided on the outer shell 20. It is easy to understand that the number of fasteners is also four. Each fastener passes through a fixing hole 24, extends into the interior of the outer shell 20, and is threadedly connected to the fixing part 15 through the threaded hole.

[0094] Furthermore, in the embodiment of the present application, the fastener is a screw, and a countersunk groove is provided on the periphery of the fixing hole 24. When the screw passes through the fixing hole 24, the nut will sink into the countersunk groove, thereby preventing the nut from being exposed and causing damage, which makes the screw unable to be removed. At the same time, it can also make the surface of the energy storage power supply 100 look smoother, thereby improving the aesthetics.
