Description

Technical Field

[0001] The present invention relates to the technical field of energy storage equipment, and in particular to an energy storage power supply. Background Art

[0002] In existing energy storage products, in order to ensure that the battery module can be stably maintained inside the shell, two battery holders need to be fixed to the two ends of the battery cell to fix the battery cell. During the assembly process, after the two battery holders are connected to the two ends of the battery cell, the assembled battery module is placed in the shell. This will result in a larger weight and volume of the energy storage, increase the floor space occupied by the energy storage product during use, and increase the manufacturing cost of the energy storage product. Summary of the Invention

[0003] The object of the present invention is to provide an energy storage power supply, which has a small weight and a small volume, thereby reducing the use area and manufacturing cost of the energy storage power supply.

[0004] In order to achieve the above technical effects, the technical solutions of the present invention are as follows:

[0005] The present invention discloses an energy storage power supply, comprising: a housing, wherein the housing defines a receiving cavity;

[0006] A battery module, comprising a plurality of battery cells and a battery holder connected to one end of the plurality of battery cells, wherein the battery holder is connected to the shell; wherein: a support portion is provided on the inner wall of the accommodating cavity, and the support portion is used to support the other end of the battery cell.

[0007] In some embodiments, the support portion includes a plurality of clamping posts provided on the inner wall of the accommodating cavity, wherein the plurality of clamping posts are arranged in multiple rows and columns, and a plurality of accommodating grooves are defined between the plurality of clamping posts. The accommodating grooves cooperate with the other end of the battery cell, and the electrical connector connecting the plurality of battery cells is clamped between two adjacent rows of clamping posts.

[0008] In some specific embodiments, the other end of each of the battery cells is clamped between four clamping posts arranged in two rows and two columns.

[0009] In some specific embodiments, the outer peripheral wall of each of the clamping posts is provided with an arc-shaped surface, and the arc-shaped surface matches the shape of the outer peripheral wall of the battery cell.

[0010] In some specific embodiments, the clamping column is provided with a plurality of weight-reducing grooves spaced apart along the center line thereof.

[0011] In some embodiments, the support portion is disposed on a top wall, a bottom wall or a side wall of the accommodating cavity.

[0012] In some embodiments, the housing includes a first shell and a second shell that are buckled together, the support portion is provided on a side wall of the first shell that is disposed toward the second shell, and the second shell is connected to the battery holder.

[0013] In some specific embodiments, the support portion and the first shell are integrally formed.

[0014] In some embodiments, one side of the battery holder is used to mount the battery cell, and the other side of the battery holder is used to mount a control circuit board.

[0015] In some embodiments, the battery bracket is further provided with a plurality of cooling fans, and the plurality of cooling fans are distributed at both ends of the control circuit board.

[0016] The present invention has the following beneficial effects: Because one end of the battery cell is connected to the battery holder and the other end is supported on the support portion of the inner wall of the housing, the inner wall of the housing serves as a structure for supporting the battery cells. Multiple battery cells can be stably secured within the housing using only one battery holder.

In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0027] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0028] Reference below Figure 1-Figure 3 The specific structure of the energy storage power supply according to the embodiment of the present invention is described.

[0029] The present invention discloses an energy storage power supply, such as Figure 1As shown, the energy storage power supply includes a housing 1 and a battery module 2. The housing 1 defines a storage cavity. The battery module 2 includes a plurality of battery cells 21 and a battery holder 22 connected to one end of the plurality of battery cells 21. The battery holder 22 is connected to the housing 1. A support portion is provided on the inner wall of the storage cavity, which is used to support the other end of the battery cell 21. It can be understood that since one end of the battery cell 21 is connected to the battery holder 22 and the other end is supported on the support portion of the inner wall of the storage cavity, the inner wall of the housing 1 is used as a structure to support the battery cell 21. In this embodiment, only one battery holder 22 is used to stably fix the plurality of battery cells 21 in the housing 1. Since only one battery holder 22 is used, the energy storage power supply of this embodiment has a smaller thickness and lighter weight, which is conducive to the miniaturization design of the energy storage power supply, reduces the floor space occupied by the energy storage power supply during use, and reduces the manufacturing cost of the energy storage power supply.

[0030] In some embodiments, as Figure 3 As shown, the support portion includes multiple latches 111 disposed on the inner wall of the accommodating cavity. The multiple latches 111 are arranged in multiple rows and columns, and multiple accommodating slots 1111 are defined between the multiple latches 111. The accommodating slots 1111 engage with the other ends of the battery cells 21, and the electrical connectors connecting the multiple battery cells 21 are snapped in between two adjacent rows of latches 111. As a result, the other ends of the battery cells 21 can be stably snapped into the latches 111, ensuring that the battery cells 21 can be stably installed in the housing 1. Furthermore, the multiple connectors connecting the battery cells 21 can be snapped in between two adjacent latches 111, 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, which could cause deformation of the electrical connectors.

[0031] In some specific embodiments, such as Figure 3 As shown, the other end of each battery cell 21 is clamped between four clamping posts 111 arranged in two rows and two columns. In this way, the battery cell 21 can be fixed from all sides, ensuring the stability of the battery cell 21 in the housing 1 and preventing the battery cell 21 from shaking or even falling during handling, transportation or use.

[0032] In some specific embodiments, such as Figure 3 As shown, the outer peripheral wall of each clamping post 111 is provided with a curved surface 1112, and the curved surface 1112 matches the shape of the outer peripheral wall of the battery cell 21. It is understood that the matching of the curved surface 1112 with the shape of the outer peripheral wall of the battery cell 21 can improve the connection effect of the multiple clamping posts 111 to the battery cell 21, thereby ensuring the stability of the battery cell 21 in the housing 1 and preventing the battery cell 21 from shaking or even falling during handling, transportation, or use.

[0033] In some more specific embodiments, Figure 3As shown, the end of the arcuate surface 1112 away from the inner wall of the receiving groove 1111 is connected to a tapered surface 1113 with a gradually increasing diameter. It is understandable that during the assembly process, the multiple battery cells 21 are first fixed to the battery holder 22, and then the battery holder 22 is placed inside the shell 1 so that the battery cells 21 are inserted into the receiving groove 1111. The end of the arcuate surface 1112 away from the inner wall of the receiving groove 1111 is connected to the tapered surface 1113 with a gradually increasing diameter, so that the opening of the receiving groove 1111 is gradually expanded, which facilitates the insertion of the battery cells 21 and thus facilitates the assembly of the energy storage power supply.

[0034] In some specific embodiments, Figure 3 As shown, the column 111 is provided with a plurality of weight-reducing grooves 1114 spaced along its centerline. This can further reduce the weight of the entire energy storage power supply, thereby facilitating the handling and transportation of the energy storage power supply and reducing the manufacturing cost of the energy storage power supply.

[0035] In some embodiments, the support portion is disposed on the top, bottom, or side walls of the accommodating cavity. Thus, during actual installation, the battery cell 21 can be positioned in a different position within the housing 1 according to actual needs. For example, when the support portion is disposed on the top or bottom wall of the accommodating cavity, the battery cell 21 is positioned upright; when the support portion is disposed on the side walls of the accommodating cavity, the battery cell 21 is positioned horizontally. This allows the energy storage power supply of this embodiment to position the battery cell 21 according to actual needs, improving the compatibility of the energy storage power supply with the operating environment.

[0036] In some embodiments, as Figure 1 As shown, the housing 1 includes a first housing 11 and a second housing 12 that interlock together. The support portion is provided on the side wall of the first housing 11 facing the second housing 12. The second housing 12 is connected to the battery holder 22. Therefore, during the actual assembly process, the battery cell 21 can be installed on the battery holder 22, and then the battery holder 22 can be fixed to the second housing 12 using a connector. Finally, the first housing 11 and the second housing 12 are interlocked. This assembly method is very convenient and improves the assembly efficiency of the energy storage power supply of this embodiment.

[0037] It should be noted here that, in this embodiment, the first shell 11 and the second shell 12 can be buckled together in the up and down direction, or in the left and right direction, or in the front and back direction. The first shell 11 and the second shell 12 can be connected by connectors such as pins, screws or rivets, or by a snap-fit structure. The second shell 12 and the battery holder 22 can be connected by connectors such as pins, screws or rivets, or by a snap-fit structure. The buckling direction of the first shell 11 and the second shell 12, the connection method of the first shell 11 and the second shell 12, and the connection method of the second shell 12 and the battery holder 22 can all be selected according to actual needs.

[0038] In some specific embodiments, the support portion and the first housing 11 are integrally formed, thereby simplifying the assembly process and improving the connection stability between the support portion and the first housing 11, thereby preventing the support portion from breaking during use, causing the battery cell 21 to tilt or even fall.

[0039] In some embodiments, as Figure 1 As shown, one side of the battery holder 22 is used to mount the battery cells 21, and the other side of the battery holder 22 is used to mount the control circuit board 23. This simplifies the structure of the battery module 2 and isolates the battery cells 21 from the control circuit board 23, preventing the negative effects of heat generated by the battery cells 21 on the control circuit board 23 and vice versa.

[0040] In some embodiments, as Figure 1 As shown, the battery holder 22 is also provided with a plurality of cooling fans 24, which are distributed at both ends of the control circuit board 23. This can better ensure that the temperature in the storage power supply cavity is always low, and avoid overheating of the battery cell 21 or the control circuit board 23.

A support portion is provided on the sidewall of the first outer shell 11 facing the second outer shell 12. The support portion comprises a plurality of latches 111 disposed on the inner wall of a receiving cavity. The latches 111 are arranged in multiple rows and columns, defining a plurality of receiving slots 1111 between the latches 111. The receiving slots 1111 engage the other ends of the battery cells 21, and the electrical connectors connecting the multiple battery cells 21 are snapped in between two adjacent rows of latches 111. The outer circumference of each latch 111 is formed with a curved surface 1112 that matches the shape of the outer circumference of the battery cell 21. The end of the curved surface 1112, facing away from the inner wall of the receiving slot 1111, is connected to a tapered surface 1113 with a gradually increasing diameter. Each latch 111 is provided with a plurality of weight-reducing slots 1114 spaced along its centerline. The battery module 2 includes multiple battery cells 21 and a battery holder 22 connected to one end of the multiple battery cells 21. One side of the battery holder 22 is used to mount the battery cells 21, and the other side of the battery holder 22 is used to mount the control circuit board 23 and is connected to the second housing 12.
