[0041] In order to facilitate the understanding of the present application, the present application will be described in more detail below in conjunction with the drawings and specific embodiments. It should be noted that when an element is described as "fixed to" another element, it can be directly on another element, or one or more intervening elements can be present therebetween. When an element is described as "connected to" another element, it can be directly connected to another element, or one or more intervening elements can be present therebetween. The terms "vertical", "horizontal", "left", "right", "inner", "outer" and similar expressions used in the specification are for illustrative purposes only.

[0042] Unless otherwise defined, all technical and scientific terms used in the specification are the same as those commonly understood by those skilled in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "and / or" used in the specification includes any and all combinations of one or more related listed items.

[0043] Please refer to Figures 1-3The embodiment of the present application provides a flow guide bar 1, which comprises a first connecting part 101 and a second connecting part 102; the first connecting part 101 is used for electrically connecting with a battery 2; the second connecting part 102 is connected with the first connecting part 101, at least two mounting parts 1021 are arranged on the second connecting part 102, and stress relief grooves 102s are arranged between any two adjacent mounting parts 1021, so that the any two adjacent mounting parts 1021 are arranged at intervals; and one mounting part 1021 is used for electrically connecting with one power terminal 3. Through the design of the flow guide bar 1, since the at least two mounting parts 1021 used for electrically connecting with the power terminal 3 are arranged at intervals through the stress relief grooves 102s, the mounting parts 1021 of the flow guide bar 1 connected with different power terminals 3 can be arranged respectively. In this way, when the power terminals 3 are mounted on the respective mounting parts 1021, they can be closely attached to the corresponding mounting parts 1021. This not only eliminates the height difference of the connection between the power terminal 3 and the conductive bar in the prior art, but also reduces the risk of poor contact between the power terminal 3 and the flow guide bar 1.

[0044] It is worth noting that in some embodiments, the number of mounting parts 1021 is three, and the number of stress relief grooves 102s is two. The number of power terminals 3 connected with the mounting parts 1021 in the energy storage power supply 100 is three, and one mounting part 1021 is used for mounting one power terminal 3.

[0045] It can be understood that the at least two mounting parts 1021 form a structure similar to a comb tooth, so that when the power terminal 3 is mounted on the mounting part 1021, the mounting part 1021 or the electronic terminal can be deformed slightly, so that the power terminal 3 and the mounting part 1021 are closely attached, and the connection gap between the power terminal 3 and the flow guide bar 1 in the prior art is eliminated, that is, the height difference of the connection between the power terminal 3 and the conductive bar in the prior art is eliminated.

[0046] It can be understood that the first connecting part 101 of the flow guide bar 1 is used for electrically connecting with the battery 2, and specifically, the first connecting part 101 of the flow guide bar 1 is electrically connected with the tab 201 of the battery 2.

[0047] It is worth noting that in some embodiments, the first connecting part 101 is electrically connected with the battery 2 in a welding manner.

[0048] It is worth noting that in some embodiments, the first connecting part 101 is bent and extended to form a buffer part 103 connected to the second connecting part 102. The provision of the buffer part 103 increases the distance between the first connecting part 101 and the second connecting part 102, thereby better adapting to the spatial layout between the battery 2 and the power terminal 3, and improving the flexibility and convenience of installation. In addition, the provision of the buffer part 103 can also alleviate the stress concentration between the battery 2 and the power terminal 3 caused by thermal expansion and cold shrinkage and other physical factors to a certain extent, further protecting the connection stability of the current-carrying bar 1 and the power terminal 3. At the same time, the shape and size of the buffer part 103 can be flexibly designed according to actual needs to meet the needs in different application scenarios.

[0049] It is worth noting that in some embodiments, the first connecting part 101 is provided with an observation hole 1011. Through the provision of the observation hole 1011, when the current-carrying bar 1 is electrically connected to the battery 2 at the first connecting part 101, the connection (such as welding) between the first connecting part 101 and the battery 2 tab 201 can be easily observed to ensure the connection quality. If the connection is poor, it can be found in time and reconnected to avoid unstable or failed power connection caused by poor connection between the current-carrying bar 1 and the battery 2. In addition, the provision of the observation hole 1011 also helps to check the connection state of the current-carrying bar 1 and the battery 2 during subsequent maintenance, ensuring the stability and reliability of the entire power transmission system. At the same time, the shape, position and number of the observation hole 1011 and other parameters can be flexibly designed according to actual needs to adapt to different specifications and layout requirements of the battery 2 and the current-carrying bar 1.

[0050] It is worth noting that in some embodiments, a mounting hole 1021s is provided in the mounting part 1021 for connecting the power terminal 3 to the mounting part 1021, such as locking the power terminal 3 to the mounting part 1021 through the first screw 12 and the mounting hole 1021s.

[0051] The application also provides a kind of energy storage power supply 100, please refer to Figure 4 And Figure 5The energy storage power supply 100 comprises a housing 4, a battery 2, an electric control board 5 and the current-carrying bar 1; the housing 4 is provided with a receiving cavity 4s, and the battery 2 and the electric control board 5 are both received in the receiving cavity 4s; the first connecting part 101 is connected to the battery 2; the electric control board 5 is provided with at least two power terminals 3, the number of the power terminals 3 is the same as the number of the mounting parts 1021, and one power terminal 3 is mounted on one mounting part 1021. In the energy storage power supply 100, at least two mounting parts 1021 for electrically connecting the power terminals 3 in the current-carrying bar 1 in the energy storage power supply 100 are spaced apart by stress relief grooves 102s, so that different power terminals 3 are connected to different mounting parts 1021 of the current-carrying bar 1 which are spaced apart, so that when the power terminals 3 are mounted on the mounting parts 1021, different power terminals 3 can be closely attached to the corresponding mounting parts 1021, that is, the height difference between the power terminals 3 and the current-carrying bar in the prior art can be eliminated, and the risk of poor contact between the power terminals 3 and the current-carrying bar 1 is reduced. In addition, since the energy storage power supply 100 is provided with a plurality of power terminals 3, large-current power supply can be realized.

[0052] It can be understood that the first connecting part 101 of the current-carrying bar 1 can be connected to the tab 201 of the battery 2. The number of the current-carrying bar 1 is two, and one current-carrying bar 1 is connected to one tab 201 of the battery 2.

[0054] It is worth noting that in some embodiments, referring to Figure 6 At least two of the power terminals 3 are flushly arranged on one side of the mounting part 1021, so that the power terminals 3 can maintain a consistent mounting height when mounted on the mounting part 1021 of the current-carrying bar 1, further ensuring the close attachment between the power terminals 3 and the current-carrying bar 1, and improving the stability and reliability of power transmission. In addition, such flush arrangement also helps to simplify the installation process of the power terminals 3 and improve the installation efficiency.

[0055] It is worth noting that in some embodiments, the first connecting part 101 is bent and extended in a direction away from the battery 2 to form a buffer part 103, which is connected to the second connecting part 102. Through this arrangement, the space adaptability between the first connecting part 101 and the battery 2 can be further increased, making the flow guide 1 more flexible and convenient when installed on the battery 2. In addition, this bent and extended design can also reduce the direct stress between the battery 2 and the flow guide 1 to some extent, protecting the connection between the flow guide 1 and the battery 2 from external physical factors, thereby improving the stability and service life of the entire power transmission system. At the same time, the buffer part 103 also has a buffering effect to some extent, which can absorb the vibration or impact that may occur during the installation or use of the battery 2, further ensuring the stable connection between the flow guide 1 and the battery 2, as well as the flow guide 1 and the power terminal 3. In addition, when the battery 2 expands, the design of the buffer part 103 can buffer the impact force of the battery 2 expansion on the energy storage power supply 100, avoiding the hard extrusion between the battery 2 and the flow guide 1 or the shell 4, thereby protecting the battery 2 and the flow guide 1.

[0056] It is worth noting that in some embodiments, referring to Figure 4 and Figure 5 , the shell 4 is provided with a reinforcing rib 401 towards the accommodation cavity 4s, and the energy storage power supply 100 further comprises a support plate 6, which is stacked on the reinforcing rib 401, and the battery 2 is stacked on the support plate 6. Through the arrangement of the reinforcing rib 401, the structural strength of the shell 4 is enhanced, and the load-bearing capacity and anti-deformation ability of the shell 4 are improved. In addition, the support plate 6 is stacked on the reinforcing rib 401, and the design of the support plate 6 can also provide a stable installation platform for the battery 2, ensuring the stability and safety of the battery 2 during installation and use.

[0057] It is worth noting that the material of the support plate 6 can be selected according to actual needs, for example, an epoxy plate can be selected.

[0058] It is worth noting that in some embodiments, the energy storage power supply 100 further comprises a buffer member 7, which is stacked between the support plate 6 and the battery 2. Through the arrangement of the buffer member 7, the vibration or impact that may occur during the installation or use of the battery 2 can be reduced to some extent, protecting the battery 2 from damage due to vibration or impact.

[0059] It is worth noting that the material of the buffer member 7 can be selected according to actual needs, for example, buffer cotton, rubber, plastic or other materials with certain elasticity and heat insulation performance can be selected.

[0060] It is worth noting that in some embodiments, referring to Figure 4 ,Figure 5 and Figure 7 The energy storage power supply 100 further comprises a sheet metal part 8 stacked between the battery 2 and the electric control panel 5; the electric control panel 5 is fixed to the sheet metal part 8; the shell 4 is provided with a fixing column 402, and the sheet metal part 8 is fixed to the fixing column 402. Through the provision of the sheet metal part 8, the sheet metal part 8 is fixed to the fixing column 402 of the shell 4, and the sheet metal part 8, the shell 4 and the battery 2 form an integral whole. The sheet metal part 8 pre-presses the battery 2, thereby enhancing the stability of the installation and use of the battery 2. In addition, the shell 4 provided with the reinforcing ribs 401 can serve as the main pressure-bearing component, so that the energy storage power supply 100 does not need to separately provide a pressure-bearing component, thereby saving material cost and installation procedures.

[0061] In some embodiments, each fixing column 402 is injection molded with a nut, and a single nut can withstand a force of 280 kgf. When six fixing columns 402 are provided, six nuts are provided, and the six nuts can collectively withstand a force of 1680 kgf, which is greater than the end expansion force 1000 kgf of the battery 2.
