[0030] In order to make the technical problem solved by the utility model, the technical scheme adopted and the technical effect reached more clear, the technical scheme of the utility model is further explained below by combining with the drawings and through specific embodiments. It can be understood that the specific embodiments described here are only used for explaining the utility model, and not for limiting the utility model. In addition, it needs to be explained that, in order to facilitate the description, only the parts related to the utility model are shown in the drawings, not all.

For the person skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0032] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0033] In the description of this embodiment, the terms "upper," "lower," "right," and "left," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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 utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0034] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] This embodiment proposes a battery, which includes a battery module and an output electrode structure mounted on the battery module. The output copper busbars of different battery modules are electrically connected through the output electrode structure. For example... Figure 1 As shown, the output pole structure includes a base 2 and a top cover 3. The base 2 is mounted on the battery mounting component 1. The mounting component 1 can be the battery end plate or a crossbeam on the tray, etc.

[0036] The existing base is fixedly installed on the battery mounting interface (such as the end plate or crossbeam in the tray). Base 2 is installed into the pre-drilled mounting holes on the mounting interface using bolts or a snap-fit ​​structure. Bolt installation increases the number of fasteners such as bolts, raising costs, and the time spent tightening bolts also affects assembly efficiency. As for the snap-fit ​​structure, the snap-fit ​​mechanism is prone to wear and even breakage during assembly and disassembly.

[0037] To solve the above problems, such as Figure 2 and Figure 3As shown, the mounting component 1 has a first hole 11 and a second hole 12 that are connected. The diameter of the first hole 11 is larger than the diameter of the second hole 12. In the output electrode structure of this embodiment, the base 2 includes a main body 21 and a variable-diameter positioning post 22. The positioning post 22 is provided at the bottom end of the main body 21. The positioning post 22 can be inserted into or through the first hole 11 and can move between the first hole 11 and the second hole 12. The positioning post 22 opens radially in the second hole 12 and engages with the second hole 12. The top cover 3 is placed on the top of the base 2. When installing the output electrode structure, the positioning post 22 is inserted into the relatively larger diameter first hole 11 and can retract radially to slide into the relatively smaller diameter second hole 12. The positioning post 22 opens radially in the second hole 12 and engages with the second hole 12. When disassembling the output electrode structure, the positioning post 22 retracts radially to slide from the second hole 12 into the first hole 11, and then exits from the first hole 11. The output electrode structure is snapped onto the mounting component 1 using a variable-diameter positioning post 22, eliminating the need for screws or other fasteners. This simplifies the output electrode structure, reduces costs, and improves assembly efficiency. Because the diameter of the positioning post 22 can change as it slides into and out of the second hole 12, wear and breakage between the positioning post 22 and the first hole 11 and second hole 12 are prevented, enhancing protection for the positioning post 22 and thus improving the safety of the output electrode structure assembly process.

[0038] like Figure 3 As shown, the mounting component 1 has two first holes 11 and one second hole 12 along the mounting direction of the base 2 (left-right direction in the figure). The second hole 12 is located between the two first holes 11 and communicates with both first holes 11. By providing a first hole 11 on each of the left and right sides of the second hole 12, the base 2 can slide from left to right or from right to left, allowing the positioning post 22 to slide into or out of the second hole 12 from both directions. That is, the base 2 has two disassembly and assembly directions, improving the ease and flexibility of disassembly and assembly of the output pole structure.

[0039] Specifically, the connecting portion between the first hole 11 and the second hole 12 is configured with a rounded corner structure 13. When the positioning post 22 slides from the first hole 11 into the second hole 12, the positioning post 22 is squeezed by the connecting portion (two rounded corner structures 13) of the first hole 11 and the second hole 12, resulting in slight deformation. This allows the positioning post 22 to smoothly slide into or out of the second hole 12 after radial contraction. The inner walls of the first hole 11 and the second hole 12 are smoothly connected through the rounded corner structure 13, reducing the friction between the rounded corner structure 13 and the radially contracted positioning post 22. This prevents the positioning post 22 from wearing or breaking, enhances the protection of the positioning post 22, and improves the safety of the output pole structure assembly and disassembly process.

[0040] In the embodiment, the diameter of the first hole 11 is 8mm-10mm, and the diameter of the second hole 12 is 6mm-8mm. For example, the diameter of the first hole 11 can be 8mm, 8.5mm, 9mm, 9.5mm or 10mm, and the diameter of the second hole 12 can be 6mm, 6.5mm, 7mm, 7.5mm or 8mm, and the diameter of the first hole 11 is required to be larger than the diameter of the second hole 12. The diameter of the positioning column 22 in the initial natural state (hereinafter referred to as the diameter of the column body of the positioning column 22) is larger than the diameter of the second hole 12 and is not much different from the diameter of the first hole 11, so that the positioning column 22 can smoothly pass into the first hole 11 and can be radially expanded at the second hole 12. When the positioning column 22 is clamped in the second hole 12, the positioning column 22 is not fully expanded, that is, it does not return to the initial natural state, and the positioning column 22 still has a tendency to expand radially, thereby ensuring that the positioning column 22 is clamped with the second hole 12, and improving the reliability and stability of the output pole structure installation.

[0041] Specifically, as shown in Figure 3 , the distance h between the communication positions of the first hole 11 and the second hole 12 is 40%-60% of the diameter of the first hole 11. The distance h between the two circular corner structures 13 arranged in the front-rear direction is 40%-60% of the diameter of the first hole 11, so that when the positioning column 22 passes through the passage between the two circular corner structures 13, it is radially contracted and slides into or out of the second hole 12. When the ratio of h to the diameter of the first hole 11 is small (less than 40%), h is too small, which causes the positioning column 22 to be unable to slide into the second hole 12 after being radially contracted, and it is difficult to complete the assembly operation of the output pole structure. When the ratio of h to the diameter of the first hole 11 is large (greater than 60%), h is too large, which causes the positioning column 22 to be very easy to slide out of the second hole 12 to the first hole 11, and it is difficult to ensure the stability of the output pole structure assembly.

[0042] As shown in Figure 4 , the positioning column 22 includes at least two clamping claws 221 arranged in the circumferential direction, one end of the clamping claw 221 is elastically arranged at the bottom end of the main body seat 21, and the at least two clamping claws 221 can be close to each other to move between the first hole 11 and the second hole 12. The at least two clamping claws 221 can be away from each other and clamped in the second hole 12. When the plurality of clamping claws 221 slide into the second hole 12 from the first hole 11, the plurality of clamping claws 221 are pressed and close to each other, so that the positioning column 22 is elastically deformed, at this time the positioning column 22 is radially contracted, so that the radially contracted positioning column 22 slides into the second hole 12. After the positioning column 22 slides into the second hole 12, the clamping claws 221 can be away from each other under the action of the elastic restoring force of the clamping claws 221, so that the positioning column 22 is radially expanded until the positioning column 22 is tightly abutted with the inner wall of the second hole 12, thereby realizing the clamping cooperation between the positioning column 22 and the second hole 12.

[0043] The positioning column 22 of the embodiment includes two oppositely arranged clamping claws 221, which are close to each other when being radially extruded, so that the diameter of the positioning column 22 is reduced. In other embodiments, the positioning column 22 can also include three or more than four clamping claws 221, which are arranged along the circumference of the positioning column 22.

[0044] Specifically, as shown in Figure 4 , the clamping claw 221 includes a clamping claw arm 2211 and a clamping claw head 2212, one end of the clamping claw arm 2211 is elastically arranged at the bottom end of the main body seat 21, and the other end of the clamping claw arm 2211 is connected with the clamping claw head 2212. The clamping claw arm 2211 is clamped in the second hole 12, and the clamping claw heads 2212 of at least two clamping claws 221 are arranged around the end of the positioning column 22, and the end is axially arranged along the positioning column 22. The projection area of the mounting component 1 is larger than the opening area of the second hole 12. The plurality of clamping claw arms 2211 collectively surround the column body of the positioning column 22, and the diameter of the column body is smaller than the diameter of the end, so that the positioning column 22 is thinned to form a column body with a smaller diameter, so that the clamping claw arm 2211 is relatively thin and is more likely to elastically deform.

[0045] Further, as shown in Figure 3 , the end is provided with a guide arc surface 220 along the circumference. When the mounting base 2 is assembled, the base 2 needs to be aligned with one of the first holes 11 and moved upwardly and downwardly until the positioning column 22 is inserted into the corresponding first hole 11. Then, the positioning column 22 is pushed into the second hole 12 from the first hole 11 in one of the left and right directions to complete the assembly of the base 2. The guide arc surface 220 guides the positioning column 22 to quickly align and insert into the corresponding first hole 11, thereby improving the assembly efficiency of the base 2.

[0046] As shown in Figure 4 and Figure 5 , one of the main body seat 21 and the upper cover 3 is provided with a first clamping part 23, and the other is provided with a second clamping part 31, and the first clamping part 23 and the second clamping part 31 are clamped and matched. The first clamping part 23 is arranged on the main body seat 21, and the second clamping part 31 is arranged on the upper cover 3, and the first clamping part 23 is a buckle head, and the first clamping part 23 is a clamping groove. Through the clamping and matching of the buckle head and the clamping groove, the assembly strength and stability of the main body seat 21 and the upper cover 3 are improved, the disassembly and assembly of the upper cover 3 are simple and easy to operate, and the assembly efficiency and assembly strength of the output pole structure are improved. In other embodiments, the main body seat 21 is provided with the second clamping part 31, and the upper cover 3 is provided with the first clamping part 23. The buckle head can be a triangular boss structure and various structures, as long as it can be clamped in the clamping groove.

[0047] The left and right sides of the top end of the main seat 21 of the embodiment are provided with a buckle head, and the left and right sides of the upper cover 3 are correspondingly provided with a clamping groove, and when the upper cover 3 is buckled on the top end of the base 2 from top to bottom, the buckle head is inserted into and clamped in the corresponding clamping groove. The number, position and specific structure of the first clamping part 23 and the second clamping part 31 can be flexibly set according to the assembly requirements, which will not be listed one by one here.

[0048] Further, as shown in Figure 5 One of the main seat 21 and the upper cover 3 is further provided with a boss 24, and the other one of the main seat 21 and the upper cover 3 is pressed on the boss 24 when the upper cover 3 is covered on the top end of the base 2. The boss 24 is located between the main seat 21 and the upper cover 3, so that the upper cover 3 and the main seat 21 are closely matched, avoiding the upper cover 3 from shaking or deviating relative to the main seat 21, improving the assembly strength and stability of the output pole structure, and also avoiding abnormal noise of the assembled output pole structure.

[0049] Specifically, the boss 24 of the embodiment has four, and the left and right sides of the top end of the main seat 21 have two, and the two bosses 24 on the same side have a first clamping part 23. In other embodiments, the number and position of the boss 24 can be flexibly adjusted according to the assembly requirements.

[0050] The battery of the embodiment can also be used on an electric device, which comprises an electric main body and a battery. The battery can be installed inside or outside the electric main body to provide stable electric energy to the electric main body. The electric main body of the embodiment can be a common fuel car, a new energy vehicle or other electric device, which is not limited here.
