Description

[0001] This application is a divisional application of patent application number 202210831941.4 (the original application was filed on July 14, 2022, and the invention was entitled "An Energy Storage Power Supply"). Technical Field

[0002] This invention relates to the field of energy storage technology, and more particularly to an energy storage power source. Background Technology

[0003] In existing energy storage products, in order to ensure that the battery module can be stably kept inside the casing, two battery brackets are needed to fix the battery cell at both ends. During the assembly process, after the two battery brackets are connected to both ends of the battery cell, the assembled battery module is placed into the casing. This results in a large weight and volume of energy storage, increasing the footprint of the energy storage product and increasing the manufacturing cost of the energy storage product. Summary of the Invention

[0004] The purpose of this invention is to provide an energy storage power source that has a small weight and a small volume, thereby reducing the area to be used and the manufacturing cost of the energy storage power source.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] This invention discloses an energy storage power supply, comprising: a housing defining a receiving cavity, the inner wall of which defines a plurality of receiving slots, the receiving slots being integrally formed with the housing; a battery module including a plurality of battery cells and a battery bracket connected to one end of each battery cell, the battery bracket being connected to the housing, and the other end of each battery cell engaging with a receiving slot; a control circuit board located within the receiving cavity; and cooling fans distributed at both ends of the control circuit board.

[0007] In some embodiments, the receiving groove is disposed on the top wall, bottom wall or side wall of the receiving cavity.

[0008] In some embodiments, the housing includes a first outer shell and a second outer shell connected together, the first outer shell and the second outer shell being connected by a connector or fastened together.

[0009] In some specific embodiments, the receiving groove is disposed on the side wall of the first housing facing the second housing.

[0010] In some embodiments, a support portion is integrally formed on the inner wall of the receiving cavity, the support portion being used to support the battery cell, and the support portion defining the receiving groove.

[0011] In some embodiments, the support includes a plurality of retaining posts disposed on the inner wall of the receiving cavity, the plurality of retaining posts defining a plurality of receiving slots.

[0012] In some specific embodiments, the outer peripheral wall of the card post is provided with an arc-shaped surface, which matches the shape of the outer peripheral wall of the battery cell.

[0013] In some specific embodiments, the battery module further includes electrical connectors that connect multiple battery cells in series or in parallel, and the electrical connectors are snapped between two adjacent rows of locking posts.

[0014] In some embodiments, the control circuit board is mounted on the battery bracket.

[0015] In some specific embodiments, the control circuit board is mounted on the side of the battery bracket away from the battery cell, and the battery bracket isolates the battery cell and the control circuit board.

[0016] The beneficial effects of this invention are as follows: Since one end of the battery cell is connected to the battery bracket and the other end is supported on the receiving groove on the inner wall of the receiving cavity, the inner wall of the housing serves as the structure supporting the battery cell. In this embodiment, multiple battery cells can be stably fixed in the housing using only one battery bracket. Because only one battery bracket is used, the energy storage power supply of this embodiment has a smaller thickness and lighter weight, which facilitates the miniaturization design of the energy storage power supply, reduces the footprint during use, and lowers the manufacturing cost. Furthermore, the cooling fans are distributed at both ends of the control circuit board, which effectively ensures that the temperature inside the receiving cavity of the energy storage power supply remains low, preventing overheating of the battery cells or the control circuit board.

[0017] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0024] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0026] Furthermore, features specified as "first" or "second" may explicitly or implicitly include one or more of those features, used to distinguish and describe features, without any order or emphasis. In the description of this invention, unless otherwise stated, "multiple" means two or more.

[0027] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0028] The following is for reference. Figures 1-3 The specific structure of the energy storage power supply according to an embodiment of the present invention is described.

[0029] This invention discloses an energy storage power source, such as... Figure 1As shown, the energy storage power supply includes a housing 1, a battery module 2, a control circuit board 23, and a cooling fan 24. The housing 1 defines a receiving cavity, and a receiving groove 1111 is provided on the inner wall of the receiving cavity. The receiving groove 1111 is integrally formed with the housing 1. The battery module 2 includes multiple battery cells 21 and a battery bracket 22 connected to one end of the multiple battery cells 21. The battery bracket 22 is connected to the housing 1. The other end of the battery cell 21 mates with the receiving groove 1111. The control circuit board 23 is located inside the receiving cavity.

[0030] It is understandable that, since one end of the battery cell 21 is connected to the battery bracket 22 and the other end is supported on the receiving groove 1111 on the inner wall of the receiving cavity, the inner wall of the housing 1 is used as the structure to support the battery cell 21. In this embodiment, multiple battery cells 21 can be stably fixed in the housing 1 using only one battery bracket 22. Because only one battery bracket 22 is used, the energy storage power supply in this embodiment has a smaller thickness and lighter weight, which is beneficial to the miniaturization design of the energy storage power supply, reduces the footprint of the energy storage power supply during use, and reduces the manufacturing cost of the energy storage power supply. In addition, the cooling fans 24 are distributed at both ends of the control circuit board 23, which can better ensure that the temperature inside the receiving cavity of the energy storage power supply remains low, avoiding overheating of the battery cell 21 or the control circuit board 23.

[0031] In some embodiments, the receiving groove 1111 is disposed on the top wall, bottom wall, or side wall of the receiving cavity. Therefore, during actual installation, the battery cell 21 can be positioned in the housing 1 according to actual needs. For example, when the receiving groove 1111 is disposed on the top or bottom wall of the receiving cavity, the battery cell 21 is placed upright; when the receiving groove 1111 is disposed on the side wall of the receiving cavity, the battery cell 21 is placed horizontally. This allows the energy storage power supply of this embodiment to place the battery cell 21 according to actual needs, improving the compatibility of the energy storage power supply with the usage environment.

[0032] In some embodiments, such as Figure 1 As shown, the housing 1 includes a first outer shell 11 and a second outer shell 12 connected together. The first outer shell 11 and the second outer shell 12 are connected by a connector or fastened to each other. Disassembling the housing 1 into the connected first outer shell 11 and second outer shell 12 facilitates assembly and improves assembly efficiency.

[0033] In some specific embodiments, the receiving groove 1111 is disposed on the side wall of the first outer shell 11 facing the second outer shell 12. Thus, in the actual assembly process, the battery cell 21 can be installed on the battery bracket 22 and then fixed to the second outer shell 12 by the battery bracket 22. Finally, the first outer shell 11 and the second outer shell 12 are fastened together, so that the side of the battery cell 21 facing away from the second outer shell 12 is completely inserted into the receiving groove 1111. This assembly method is very convenient and improves the assembly efficiency of the energy storage power supply in this embodiment.

[0034] It should be noted that in this embodiment, the first outer shell 11 and the second outer shell 12 can be fastened together vertically, horizontally, or front-back. The first outer shell 11 and the second outer shell 12 can be connected by connectors such as pins, screws, or rivets, or by a snap-fit ​​structure. The second outer shell 12 and the battery bracket 22 can be connected by connectors such as pins, screws, or rivets, or by a snap-fit ​​structure. The fastening direction of the first outer shell 11 and the second outer shell 12, the connection method of the first outer shell 11 and the second outer shell 12, and the connection method of the second outer shell 12 and the battery bracket 22 can all be selected according to actual needs.

[0035] In some embodiments, a support portion is integrally formed on the inner wall of the receiving cavity. The support portion supports the battery cell 21 and defines a receiving groove 1111. Thus, the other end of the battery cell 21 can stably engage with the support portion, and the support portion can restrict and support the battery cell 21, thereby ensuring that the battery cell 21 can be stably installed in the housing 1.

[0036] In some specific embodiments, such as Figure 3 As shown, the support includes multiple locking posts 111 on the inner wall of the receiving cavity. Multiple receiving grooves 1111 are defined between the locking posts 111. The receiving grooves 1111 engage with the other end of the battery cell 21, and the electrical connectors connecting the multiple battery cells 21 are engaged between adjacent rows of locking posts 111. Thus, the other end of the battery cell 21 can be stably engaged with the locking posts 111, ensuring that the battery cell 21 can be stably installed inside the housing 1. Furthermore, the connectors connecting the multiple battery cells 21 can be engaged between adjacent rows of locking posts 111, thus preventing the electrical connectors connecting the multiple battery cells 21 in series or parallel from being pressed against the inner wall of the housing 1, thereby avoiding deformation of the electrical connectors.

[0037] In some more specific embodiments, such as Figure 3 As shown, the other end of each battery cell 21 is snapped between four locking posts 111 arranged in two rows and two columns. This allows the battery cell 21 to be fixed from all sides, ensuring the stability of the battery cell 21 within the housing 1 and preventing the battery cell 21 from shaking or even falling off during handling, transportation, or use.

[0038] In some specific embodiments, such as Figure 3As shown, each locking post 111 has an arc-shaped surface 1112 on its outer peripheral wall, and the arc-shaped surface 1112 matches the shape of the outer peripheral wall of the battery cell 21. It can be understood that matching the shape of the arc-shaped surface 1112 with the outer peripheral wall of the battery cell 21 can improve the connection effect of multiple locking posts 111 to the battery cell 21, thereby ensuring the stability of the battery cell 21 within the housing 1 and preventing the battery cell 21 from shaking or even falling off during handling, transportation, or use.

[0039] In some more specific embodiments, such as Figure 3 As shown, the end of the arc-shaped surface 1112 away from the inner wall of the receiving groove 1111 is connected to a conical surface 1113 with a gradually increasing diameter. It can be understood that during assembly, multiple battery cells 21 are first fixed to the battery bracket 22, and then the battery bracket 22 is placed inside the housing 1, allowing the battery cells 21 to be inserted into the receiving groove 1111. The conical surface 1113 with a gradually increasing diameter at the end of the arc-shaped surface 1112 away from the inner wall of the receiving groove 1111 makes the opening of the receiving groove 1111 gradually widening, facilitating the insertion of the battery cells 21 and thus facilitating the assembly of the energy storage power supply.

[0040] In some specific embodiments, such as Figure 3 As shown, the locking post 111 is provided with multiple weight-reducing grooves 1114 spaced apart along its center line. This further reduces the weight of the entire energy storage power supply, thereby facilitating the handling and transportation of the energy storage power supply and reducing its manufacturing cost.

[0041] In some specific embodiments, the support portion and the first outer shell 11 are integrally formed. This simplifies the assembly process and improves the connection stability between the support portion and the first outer shell 11, preventing the support portion from breaking during use and causing the battery cell 21 to tilt or even fall off.

[0042] In some embodiments, the battery module 2 further includes electrical connectors that connect multiple battery cells 21 in series or in parallel. The electrical connectors are snapped between two adjacent rows of latches 111. It is understood that snapping the electrical connectors between two adjacent rows of latches 111 allows the electrical connectors to be held relatively stably within the receiving cavity, ensuring the stability of the series and parallel connections between the multiple battery cells 21, thereby reducing the probability of electrical connection failure between the multiple battery cells 21.

[0043] In some embodiments, such as Figure 1 As shown, the control circuit board 23 is mounted on the battery bracket 22. It is understood that mounting the control circuit board 23 on the battery bracket 22 ensures the stability of the control circuit board 23.

[0044] In some specific embodiments, such as Figure 1As shown, the control circuit board 23 is mounted on the side of the battery bracket 22 away from the battery cell 21, and the battery bracket 22 isolates the control circuit board 23 from the battery cell 21. This simplifies the structure of the battery module 2 and isolates the battery cell 21 from the control circuit board 23, preventing the heat generated by the battery cell 21 from adversely affecting the control circuit board 23, and vice versa.

[0046] The following is for reference. Figures 1-3 This invention describes an energy storage power supply according to a specific embodiment of the present invention.

[0047] The energy storage power supply includes a housing 1 and a battery module 2. The housing 1 includes a first outer shell 11 and a second outer shell 12 that are interlocked. A support portion is provided on the side wall of the first outer shell 11 facing the second outer shell 12. The support portion includes multiple locking posts 111 on the inner wall of the receiving cavity. The multiple locking posts 111 are arranged in multiple rows and columns, and multiple receiving slots 1111 are defined between the multiple locking posts 1111. The receiving slots 1111 mate with the other end of the battery cell 21. Electrical connectors connecting the multiple battery cells 21 are snapped between two adjacent rows of locking posts 111. The outer peripheral wall of each locking post 111 is provided with an arc-shaped surface 1112, and the shape of the arc-shaped surface 1112 matches the shape of the outer peripheral wall of the battery cell 21. The inner wall end of the arc-shaped surface 1112 away from the receiving slot 1111 is connected to a tapered surface 1113 with a gradually increasing diameter. Each locking post 111 is provided with multiple weight-reducing slots 1114 that are spaced apart along its center line. The battery module 2 includes multiple battery cells 21 and a battery bracket 22 connected to one end of the multiple battery cells 21. One side of the battery bracket 22 is used to mount the battery cells 21, and the other side of the battery bracket 22 is used to mount the control circuit board 23 and is connected to the second housing 12. The battery bracket 22 is also equipped with four cooling fans 24, which are distributed at both ends of the control circuit board 23.
