Description

Technical Field

[0001] This application relates to the field of battery technology, and in particular to an anti-loosening component, a battery, and an electric two-wheeler. Background Technology

[0002] Some batteries use cylindrical cells, which are stacked to form a cell module. Each cell module has multiple nickel plates on both sides, welded to the end faces of the cylindrical cells for electrical conduction. To prevent the nickel plates from loosening due to impacts or vibrations during driving, related technologies use clamps at opposite ends of the cell module. Multiple pull rods are placed between the clamps, and tightening these rods secures the nickel plates at both ends of the cylindrical cell, reducing the risk of loosening.

[0003] However, in order to avoid interference between the pull rod and the cylindrical battery cell, the pull rod can only be located on the periphery of the battery cell module, with both ends of the pull rod connected to the edge of the clamping plate. As a result, the pull rod has a poor force application effect on the middle position of the clamping plate, which leads to a poor clamping effect of the clamping plate on the nickel sheets at both ends of the cylindrical battery cell.

[0027] The following is for reference. Figures 1 to 3 This application describes an anti-loosening component, a battery, and an electric two-wheeler according to embodiments thereof.

[0028] According to the anti-loosening component of the first aspect of this application, such as Figures 1 to 3 As shown, it includes two clamping plates 100, multiple tie rods 200 and two abutment structures 300.

[0029] Two clamping plates 100 are arranged side by side, and multiple pull rods 200 are located between the two clamping plates 100 to limit the distance between the two clamping plates 100. Specifically, the multiple pull rods 200 can be connected to the clamping plates 100 near the edge to avoid interference with the cylindrical battery cell.

[0030] Two abutting structures 300 are located on opposite sides of the two clamping plates 100. The two ends of the multiple pull rods 200 are connected to the two abutting structures 300 respectively. The abutting structure 300 abuts at least the middle position of the opposite side of the two clamping plates 100. For example, the abutting structure 300 may abut only the middle position of the opposite side of the two clamping plates 100, or it may abut not only the middle position of the opposite side of the two clamping plates 100, but also other positions of the opposite side of the two clamping plates 100. This will not be elaborated here.

[0031] In this application, when assembling the battery cell module, multiple cylindrical battery cells are clamped between two clamping plates 100. The length direction of the cylindrical battery cells is parallel to the length direction of the pull rod 200. The two clamping plates 100 press against the nickel sheets at the ends of the cylindrical battery cells to prevent the nickel sheets at the ends of the cylindrical battery cells from coming loose.

[0032] According to the anti-loosening structure of this utility model embodiment, in addition to the position near the pull rod 200, that is, the edge position of the clamping plate 100, which can effectively clamp the cylindrical battery cell, the clamping plate 100 also includes two abutment structures 300. The two abutment structures 300 are respectively located on the opposite sides of the two clamping plates 100. The two ends of the multiple pull rods 200 are respectively connected to the two abutment structures 300. The abutment structures 300 abut at least at the middle position of the opposite side of the two clamping plates 100. In this way, the abutment structures 300 can apply opposing forces to the middle position of the two clamping plates 100, so that the middle position of the clamping plate 100 can also effectively clamp the cylindrical battery cell in the middle, so that the clamping effect of each position of the clamping plate 100 is good, thereby making the anti-loosening effect of the nickel sheet better.

[0033] refer to Figure 1 As shown, in some embodiments of this application, both clamping plates 100 are provided with multiple through holes 101, and the two ends of the pull rod 200 are respectively passed through the corresponding through holes 101 on the two clamping plates 100. The pull rod 200 is threaded with a locking nut 201 on the opposite side of the two clamping plates 100.

[0034] In this embodiment, when assembling the battery cell module, two clamping plates 100 can be respectively attached to the ends of the cylindrical battery cell. Then, the pull rod 200 is inserted through the corresponding through holes 101 on the two clamping plates 100. Next, a locking nut 201 is threaded onto the opposite side of the two clamping plates 100. Finally, the locking nut 201 is tightened so that the clamping plates 100 are pressed against the cylindrical battery cell. This operation is more convenient and saves more time and effort. Moreover, by rotating the locking nut 201, the degree to which the edge of the clamping plate 100 presses against the cylindrical battery cell can be adjusted. This can prevent the edge of the clamping plate 100 from pressing against the cylindrical battery cell too much, which could damage the cylindrical battery cell, and also prevent the edge of the clamping plate 100 from not pressing against the cylindrical battery cell enough, which would reduce the effect of preventing the nickel sheet from loosening.

[0035] refer to Figure 1 As shown, in some embodiments of this application, the abutment structure 300 is provided with a plurality of first sleeve holes, and is respectively sleeved on a plurality of pull rods 200 through the plurality of first sleeve holes, and the locking nut 201 is located on the opposite side of the two abutment structures 300.

[0036] In this embodiment, when assembling the battery cell module, the abutment structure 300 is respectively fitted onto the multiple pull rods 200 through multiple first sleeve holes, and finally the locking nut 201 is tightened. This makes assembly more convenient and makes the connection of the abutment structure 300 more stable.

[0037] refer to Figure 1 and Figure 2 As shown, in some embodiments of this application, the abutment structure 300 includes a connecting portion 301 and a plurality of abutment bolts 302. The connecting portion 301 is connected to all the tie rods 200, and the plurality of abutment bolts 302 are threadedly connected to the connecting portion 301. The abutment bolts 302 abut against the opposite sides of the two clamping plates 100. For example, the plurality of abutment bolts 302 may abut against the middle position of the clamping plate 100.

[0038] In this embodiment, rotating the abutment bolt 302 causes it to abut against the middle position of the two opposing sides of the clamping plates 100, thereby effectively clamping the cylindrical battery cell in the middle position of the clamping plates 100. Furthermore, rotating the abutment bolt 302 also adjusts the clamping degree of the middle position of the clamping plates 100 against the cylindrical battery cell. This prevents both excessive clamping of the cylindrical battery cell by the middle position of the clamping plates 100, which could damage it, and insufficient clamping, which could reduce the effectiveness of preventing the nickel sheet from loosening.

[0039] refer to Figure 1 As shown, in some embodiments of this application, the connecting part 301 includes a vertical bar 303, a horizontal bar 304, and a plurality of connecting bars 305. The vertical bar 303 is located at the middle position in the width direction of the clamping plate 100 and extends along the height direction of the clamping plate 100. Part of the abutment bolts 302 are threadedly connected to the vertical bar 303. The horizontal bar 304 is located at the middle position in the height direction of the clamping plate 100 and extends along the width direction of the clamping plate 100. The horizontal bar 304 is connected to the vertical bar 303, and another part of the abutment bolts 302 are threadedly connected to the horizontal bar 304. The plurality of connecting bars 305 are respectively connected to the vertical bar 303 and the plurality of pull rods 200.

[0040] In this embodiment, the connecting part 301 includes a vertical bar 303 and a horizontal bar 304. The vertical bar 303 is located at the middle position in the width direction of the clamping plate 100 and extends along the height direction of the clamping plate 100. The horizontal bar 304 is located at the middle position in the height direction of the clamping plate 100 and extends along the width direction of the clamping plate 100. Both the vertical bar 303 and the horizontal bar 304 are threaded with multiple abutment bolts 302. In this way, the clamping effect on the middle position of the clamping plate 100 is better, thereby making the clamping of the cylindrical battery cell in the middle position of the clamping plate 100 more comprehensive and the clamping effect better.

[0041] refer to Figure 1 and Figure 3 As shown, in some embodiments of this application, the anti-loosening assembly further includes two mounting plates 400, which are respectively disposed on the top of the two clamping plates 100. The two mounting plates 400 can be moved and adjusted in a direction that moves closer to or further away from each other. The mounting plates 400 are provided with a plurality of connecting holes 401.

[0042] In this embodiment, a mounting plate 400 is provided at the top of the clamping plate 100. The mounting plate 400 is located at the top of the cell module. When the cell module needs to be installed inside the battery casing, the operator can grasp the mounting plate 400 to move the cell module into the casing, making transportation more convenient and suitable for situations where the casing space is limited. At the same time, the connection hole 401 of the cell module is located on its top mounting plate 400, near the opening at the top of the casing, making it easier to install and fix the cell module with bolts, and improving its practicality. In addition, the two mounting plates 400 can be moved and adjusted in a direction that moves closer or further apart from each other. This can accommodate situations where there are slight errors in the size of the cell module and the size of the battery casing, making installation more convenient.

[0043] refer to Figure 1 and Figure 3 As shown, in some embodiments of this application, the bottom end of the mounting plate 400 is bent to form a connecting plate 402. The connecting plate 402 is provided with a plurality of oblong holes 403. The oblong holes 403 extend along the arrangement direction of the two clamping plates 100. Fasteners 404 are installed between the connecting plate 402 and the top end of the clamping plate 100. The fasteners 404 pass through the oblong holes 403.

[0044] In this embodiment, the fastener 404 is loosened, and then the mounting plate 400 is moved along the arrangement direction of the two clamping plates 100 so that the fastener 404 passes through different positions in the length direction of the oblong hole 403. Finally, the fastener 404 is tightened to adjust the position of the mounting plate 400. The structure is simple and the adjustment is convenient.

[0045] It should be noted that the two mounting plates 400 can also be adjusted in other ways, which will not be elaborated here.

[0046] refer to Figure 1 As shown, in some embodiments of this application, the anti-loosening assembly further includes an insulating plate 500, which is located between two clamping plates 100.

A first bearing strip 502 is provided on both sides of the bottom end of the insulating plate 500, and a second bearing strip 102 is provided on the side of the bottom end of the two clamping plates 100 that are close to each other.

[0047] In this embodiment, the insulating plate 500 is made of an electrically insulating material. When the cylindrical battery cell comprises two sets arranged side by side, the insulating plate 500 can be located between the two sets of cylindrical battery cells to electrically insulate them. This prevents the nickel sheets on the adjacent sides of the two sets of cylindrical battery cells from contacting each other, thus avoiding short circuits and affecting the electrical conduction of the nickel sheets. The bottom ends of the insulating plate 500 are respectively provided with first support strips 502 on both sides, and the bottom ends of the two clamping plates 100 are respectively provided with second support strips 102 on the adjacent sides. The first support strips 502 and the second support strips 102 can cooperate to support all the cylindrical battery cells, preventing the cylindrical battery cells from directly contacting the battery casing and reducing short circuits and leakage.

[0048] It should be noted that the clamp 100 can also be made of electrically insulating material, which will not be elaborated here.
