Description

Technical Field

[0001] The utility model relates to an output pole protection device and a battery. Background Art

[0002] In the aspects of electric vehicles and energy storage in the new energy industry, the structures of the high-voltage output pole support member and the cover of the battery module are extremely important. Currently, there is only one opening method for the output pole cover of the front shell module. The module is placed in the battery pack. Due to the limited space in the pack, when installing high-voltage connecting wires or performing repair operations, the existing single opening method cannot handle some repair problems. When facing problems that cannot be solved by the existing opening of the cover, traditionally, it is necessary to disassemble the output pole cover, and the high-voltage output is directly exposed, which is likely to cause safety risks. At the same time, the cover disassembly operation increases the process steps, and it is easy to miss installing the cover later. Moreover, frequent disassembly and assembly are likely to cause damage to the cover.

[0003] In view of this, it is necessary to improve the existing output pole protection device to solve the above problems. Summary of the Utility Model

In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0033] As Figures 1 to 9 shown, the battery 100 of the present utility model includes an end plate 2 and an output pole protection device 1.

[0034] The end plate 2, as one of the main structural members providing the overall strength of the battery 100, is generally made of metal aluminum and can be a profile or cast aluminum.

[0035] As Figures 5 to 7 shown, the output pole protection device 1 includes: an output pole support member 11 provided with an open end 110; and a cover 12 provided at the open end 110 of the output pole support member 11.

[0036] The output pole support member 11 is made of plastic and is embedded with bolts to be assembled on the end plate 2 to provide the interconnection and installation support of the module output bus bar.

[0037] Among them, the cover 12 includes a first cover body 121 pivotally connected to the output pole support member 11 along the Y direction, a second cover body 122 pivotally connected to the first cover body 121 along the X direction, and elastic limiting members 114 provided on both sides of the output pole support member 11 along the X direction. Both the first cover body 121 and the second cover body 122 are used to open and expose the inside of the output pole support member 11. Among them, the first cover body 121 opens along the X direction, and the second cover body 122 opens along the Y direction. The cover 12 is used to cooperate with the end plate to wrap the module output bus bar, ensuring the high-voltage safety inside the battery pack.

[0038] As Figures 2 to 4 shown, in this embodiment, an installation groove 21 is formed on the end plate 2, and the output pole protection device 1 is detachably received in the installation groove 21. Further, the output pole protection device 1 is fixed to the end plate 2 by bolts.

[0039] An avoidance groove 22 is formed at one end of the installation groove 21 along the X direction. The avoidance groove 22 is used to make way for the rotation of the first cover body 121 so that the rotation angle of the first cover body 121 is greater than 100 degrees, so as to better expose the module output tab.

[0040] In this embodiment, a limiting groove 23 is formed on the end plate 2 adjacent to the installation groove 21. The elastic limiting member 114 is inserted into the limiting groove 23 along the Y direction, and the limiting groove 23 limits the up and down movement of the output pole support member 11.

[0041] As Figure 8 shown, the first cover body 121 is detachably arranged relative to the output pole support member 11.

[0042] The first cover body 121 includes a first plate portion 1215, a second plate portion 1216 and a third plate portion 1217. The second plate portion 1216 and the third plate portion 1217 are relatively spaced apart along the X direction on both sides of the first plate portion 1215 and are angularly connected. In this embodiment, both the second plate portion 1216 and the third plate portion 1217 are perpendicularly connected to the first plate portion 1215.

[0043] A gap is left between the first plate portion 1215 and the output pole support member 11 for easy installation.

[0044] In addition, a rotating shaft 1211 is provided on one side of the second plate portion 1216 close to the output pole support member 11 along the Z direction. A clamping claw 111 for clamping the rotating shaft 1211 is provided on one side of the output pole support member 11 along the X direction. The rotating shaft 1211 is rotatably arranged relative to the clamping claw 111. The clamping claw 111 has an opening 112, and the rotating shaft 1211 can be disengaged from the clamping claw 111 at the opening 112 under an external force, so as to achieve the effect of making the first cover body 121 detachable relative to the output pole support member 11. In this embodiment, the clamping claw 111 and the rotating shaft 1211 are arranged at one end close to the avoidance groove 22.

[0045] A first buckling portion 1212 is provided on one side of the third plate portion 1217 close to the output pole support member 11 along the Z direction. A second buckling portion 113 for buckling with the first buckling portion 1212 is provided on the output pole support member 11. A first handle 1213 for holding is further protruded on the third plate portion 1217 along the X direction.

[0046] Among them, the first clamping portion 1212 and the second clamping portion 113 are clamped, so that the first cover 121 and the output pole support 11 are relatively fixed. When the first cover 121 needs to be opened, the user needs to hold the first handle 1213 and drive the rotating shaft 1211 of the first cover 121 to rotate relative to the clamping claw 111.

[0047] The rotating shaft 1211 and the clamping claw 111 are set to be rotationally matched. Thus, when installing the high-voltage connecting wire or performing repair operations, only by opening the first cover 121 can the module output tab be exposed, rather than having to disassemble the first cover 121.

[0048] Such as Figure 9 As shown, in this embodiment, the second cover 122 is fixedly connected to the first cover 121. Of course, it is also an optional solution that the second cover 122 and the first cover 121 are detachably arranged.

[0049] The second cover 122 includes a fourth plate portion 1224, a fifth plate portion 1225 and a sixth plate portion 1226 that are angularly connected to the fourth plate portion 1224.

[0050] The fourth plate portion 1224 is angularly connected to the first plate portion 1215 through a plastic connecting piece 1221 and is located between the second plate portion 1216 and the third plate portion 1217. The plastic connecting piece 1221 is used to make the second cover 122 in an open state relative to the first cover 121 under the action of an external force, or to make the second cover 122 return to the closed state when the external force is lost. In this embodiment, the fourth plate portion 1224 is used to cover the top of the first cover 121 and can be opened to expose the inside of the output pole support 11.

[0051] A plurality of plastic connecting pieces 1221 are arranged at intervals along the X direction. A thinning area 1227 is provided at the connection position between the plastic connecting piece 1221 and the first plate portion 1215. Since the plastic connecting piece 1221 is provided with the thinning area 1227 and the plastic connecting piece 1221 is respectively connected to the fourth plate portion 1224 and the fifth plate portion 1225, even if there is an irregular operation of not buckling after the second cover 122 is opened, the second cover 122 itself will slowly fall back, avoiding the long-term exposure of the high-voltage live body and the risk of accidental contact by personnel, and increasing the safety during the installation process.

[0052] Clamping grooves 1214 are provided on the sides of the second plate portion 1216 and the third plate portion 1217 away from the plastic connecting piece 1221. The fifth plate portion 1225 is provided with a clamping block 1222 extending along the X direction for inserting into the clamping groove 1214 and a second handle 1223 protruding in the Y direction for holding.

[0053] The clamping block 1222 is inserted into the clamping groove 1214, so as to realize the relative fixation of the first cover body 121 and the second cover body 122. The second handle 1223 is used for the user to hold to open the first cover body 121.

[0054] The sixth plate portion 1226 extends downward along the Z direction from one end of the fifth plate portion 1225 away from the fourth plate portion 1224. The sixth plate portion 1226 is spaced from the cover 12 to leave an observation window, and can also be held by the user.

[0055] By providing the second cover body 122, when installing the high-voltage connection wire or performing repair operations, only the second cover body 122 needs to be opened to expose the module output bus bar, which is not likely to cause safety risks, eliminates the operation steps of disassembly, is not likely to cause omission of the installation of the cover 12, and will not cause damage to the cover 12 due to frequent disassembly and assembly.

[0056] The output pole protection device 1 and the battery 100 of the present utility model can be opened from two directions for maintenance operations to cope with different maintenance conditions; high-voltage connection assembly or repair can be achieved without removing the cover, improving the safety of the product during use and ensuring the life and property safety of the operating personnel.

[0057] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0058] The above embodiments only express several implementation manners of the present utility model, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
