Description

Technical Field

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

[0002] Some batteries use cylindrical cells, with multiple cylindrical cells forming 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, with multiple pull rods between the clamps. Tightening these pull rods clamps the nickel plates at both ends of the cylindrical cells, reducing the risk of loosening. However, to avoid interference between the pull rods and the cylindrical cells, the pull rods can only be located on the periphery of the cell module, with both ends connected to the edges of the clamps. This results in poor force application from the pull rods to the center of the clamps, leading to a weaker clamping effect on the nickel plates at the ends of the central cylindrical cell. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a battery that provides a better clamping effect on the cylindrical battery cell at all positions of the clamping plate, thereby improving the anti-loosening effect of the nickel sheet.

[0004] This utility model also proposes an electric two-wheeled vehicle.

[0005] A battery according to a first aspect embodiment of the present invention includes a housing, an anti-loosening component, a cell module, and a BMS module. The anti-loosening component is disposed within the housing and includes two clamping plates, multiple pull rods, and two abutment structures. The two clamping plates are arranged side by side, the multiple pull rods are disposed between the two clamping plates, and the two abutment structures are respectively located on opposite sides of the two clamping plates. The two ends of the multiple pull rods are respectively connected to the two abutment structures, and the abutment structures abut at least at the middle position of the opposite sides of the two clamping plates. The cell module includes multiple cylindrical cells clamped between the two clamping plates. The BMS module includes a BMS mounting bracket, a BMS main control board, and a BMS slave control board. The BMS mounting bracket is disposed within the housing and located above the cell module. The BMS main control board and the BMS slave control board are mounted on the BMS mounting bracket.

[0006] The battery according to the embodiments of the present invention has at least the following beneficial effects: In this application, when assembling the battery, multiple cylindrical cells are clamped between two clamping plates, with the length direction of the cylindrical cells parallel to the length direction of the pull rod. The two clamping plates press against the nickel sheets at the ends of the cylindrical cells to prevent the nickel sheets at the ends of the cylindrical cells from coming loose. Then, the assembled anti-loosening components and cell modules are placed inside the housing, and then the BMS module is installed inside the housing and positioned above the cell modules. According to the battery embodiment of this utility model, in addition to the effective clamping of the cylindrical battery cell near the pull rod (i.e., at the edge of the clamping plate), the clamping plate also includes two abutment structures. These two abutment structures are located on opposite sides of the two clamping plates. The two ends of multiple pull rods are connected to the two abutment structures, and each abutment structure abuts at least the middle of the opposite side of the two clamping plates. Thus, the abutment structures can apply opposing forces to the middle of the two clamping plates, ensuring that the middle of the clamping plates can also effectively clamp the central cylindrical battery cell.

[0022] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0023] The following is for reference. Figures 1 to 8 This invention describes a battery and an electric two-wheeler according to embodiments of the present invention.

[0024] like Figures 1 to 8 As shown, the battery according to the first aspect of the present invention includes a casing 100, an anti-loosening component 200, a cell module 300, and a BMS module 400.

[0025] An anti-loosening assembly 200 is disposed within the housing 100. The anti-loosening assembly 200 includes two clamping plates 201, multiple pull rods 202, and two abutment structures 203. The two clamping plates 201 are arranged side by side, and the multiple pull rods 202 are disposed between the two clamping plates 201 to prevent the two clamping plates 201 from moving away from each other. Specifically, the multiple pull rods 202 can be connected to the clamping plates 201 near the edge to avoid interference with the cylindrical battery cell 301. Two abutting structures 203 are located on opposite sides of the two clamping plates 201. The two ends of the multiple pull rods 202 are connected to the two abutting structures 203 respectively. The abutting structure 203 abuts at least the middle position of the opposite side of the two clamping plates 201. For example, the abutting structure 203 may abut only the middle position of the opposite side of the two clamping plates 201, or it may abut not only the middle position of the opposite side of the two clamping plates 201, but also other positions of the opposite side of the two clamping plates 201. This will not be elaborated here.

[0026] The battery module 300 includes multiple cylindrical battery cells 301, which are clamped between two clamping plates 201. The length direction of the cylindrical battery cells 301 is parallel to the length direction of the pull rod 202. The two clamping plates 201 press against the nickel sheet at the end of the cylindrical battery cells 301 to prevent the nickel sheet at the end of the cylindrical battery cells 301 from coming loose.

[0027] The BMS module 400 includes a BMS mounting bracket 401, a BMS main control board 402, and a BMS slave control board 403. The BMS mounting bracket 401 is located inside the housing 100 and above the cell module 300. The BMS main control board 402 and the BMS slave control board 403 are mounted on the BMS mounting bracket 401. The BMS main control board 402 and the BMS slave control board 403 work together to prevent overcharging and over-discharging of the battery, extend the battery's lifespan, and monitor the battery's status.

[0028] In this application, when assembling the battery, multiple cylindrical cells 301 are clamped between two clamping plates 201. The length direction of the cylindrical cells 301 is parallel to the length direction of the pull rod 202. The two clamping plates 201 press against the nickel sheets at the ends of the cylindrical cells 301 to prevent the nickel sheets at the ends of the cylindrical cells 301 from coming loose. Then, the assembled anti-loosening assembly 200 and the cell module 300 are placed inside the housing 100. Finally, the BMS module 400 is installed inside the housing 100 and positioned above the cell module 300.

[0029] According to the anti-loosening structure of this utility model embodiment, in addition to the position near the pull rod 202, that is, the edge position of the clamping plate 201, which can effectively clamp the cylindrical battery cell 301, the clamping plate 201 also includes two abutment structures 203. The two abutment structures 203 are respectively located on the opposite side of the two clamping plates 201. The two ends of the multiple pull rods 202 are respectively connected to the two abutment structures 203. The abutment structures 203 abut at least at the middle position of the opposite side of the two clamping plates 201. In this way, the abutment structures 203 can apply opposing forces to the middle position of the two clamping plates 201, so that the middle position of the clamping plate 201 can also effectively clamp the cylindrical battery cell 301 in the middle, so that the clamping effect of each position of the clamping plate 201 is good, thereby making the anti-loosening effect of the nickel sheet better. In addition, in this invention, a BMS module 400 is provided inside the housing 100. The BMS module 400 can prevent the battery from overcharging and over-discharging, extend the battery's service life, and monitor the battery's status.

[0030] refer to Figure 2 and Figure 3 As shown, in some embodiments of this application, both clamping plates 201 are provided with multiple through holes 204, and the two ends of the pull rod 202 are respectively passed through the corresponding through holes 204 on the two clamping plates 201. The pull rod 202 is threaded with a locking nut 205 on the opposite side of the two clamping plates 201.

[0031] In this embodiment, when assembling the battery cell module 300, two clamping plates 201 can be respectively attached to the ends of the cylindrical battery cell 301. Then, the pull rod 202 is inserted through the corresponding through holes 204 on the two clamping plates 201. Next, a locking nut 205 is threaded onto the opposite side of the two clamping plates 201. Finally, the locking nut 205 is tightened so that the clamping plates 201 press against the cylindrical battery cell 301. This operation is more convenient and saves more time and effort. Moreover, by rotating the locking nut 205, the degree to which the edge of the clamping plate 201 presses against the cylindrical battery cell 301 can be adjusted. This can prevent the edge of the clamping plate 201 from pressing against the cylindrical battery cell 301 too much, which would damage the cylindrical battery cell 301, and can also prevent the edge of the clamping plate 201 from pressing against the cylindrical battery cell 301 too little, which would reduce the effect of preventing the nickel sheet from loosening.

[0032] refer to Figure 2 and Figure 3 As shown, in some embodiments of this application, the abutment structure 203 is provided with a plurality of first sleeve holes, and is respectively sleeved on a plurality of pull rods 202 through the plurality of first sleeve holes, and the locking nut 205 is located on the opposite side of the two abutment structures 203.

[0033] In this embodiment, when assembling the battery cell module 300, the abutment structure 203 is respectively fitted onto the multiple pull rods 202 through multiple first sleeve holes, and finally the locking nut 205 is tightened. This makes assembly more convenient and makes the connection of the abutment structure 203 more stable.

[0034] refer to Figures 2 to 4 As shown, in some embodiments of this application, the abutment structure 203 includes a connecting portion 206 and a plurality of abutment bolts 207. The connecting portion 206 is connected to all the tie rods 202, and the plurality of abutment bolts 207 are threadedly connected to the connecting portion 206. The abutment bolts 207 abut against the opposite sides of the two clamping plates 201. For example, the plurality of abutment bolts 207 may abut against the middle position of the clamping plate 201.

[0035] In this embodiment, rotating the abutment bolt 207 allows it to abut against the middle position of one of the two opposing clamping plates 201, thereby effectively clamping the cylindrical battery cell 301 in the middle position of the clamping plates 201. Furthermore, rotating the abutment bolt 207 also adjusts the clamping degree of the middle position of the clamping plates 201 against the cylindrical battery cell 301. This prevents both excessive clamping of the middle position of the clamping plates 201, which could damage the cylindrical battery cell 301, and insufficient clamping, which could reduce the effectiveness in preventing the nickel sheet from loosening.

[0036] refer to Figure 2 and Figure 3As shown, in some embodiments of this application, the connecting part 206 includes a vertical bar 208, a horizontal bar 209, and a plurality of connecting bars 210. The vertical bar 208 is located at the middle position in the width direction of the clamping plate 201 and extends along the height direction of the clamping plate 201. Part of the abutment bolts 207 are threadedly connected to the vertical bar 208. The horizontal bar 209 is located at the middle position in the height direction of the clamping plate 201 and extends along the width direction of the clamping plate 201. The horizontal bar 209 is connected to the vertical bar 208, and another part of the abutment bolts 207 are threadedly connected to the horizontal bar 209. The plurality of connecting bars 210 are respectively connected to the vertical bar 208 and the plurality of pull rods 202.

[0037] In this embodiment, the connecting part 206 includes a vertical bar 208 and a horizontal bar 209. The vertical bar 208 is located at the middle position in the width direction of the clamping plate 201 and extends along the height direction of the clamping plate 201. The horizontal bar 209 is located at the middle position in the height direction of the clamping plate 201 and extends along the width direction of the clamping plate 201. Both the vertical bar 208 and the horizontal bar 209 are threaded with multiple abutment bolts 207. In this way, the clamping effect on the middle position of the clamping plate 201 is better, so that the clamping of the cylindrical battery cell 301 in the middle position of the clamping plate 201 is more comprehensive and the clamping effect is better.

[0038] refer to Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments of this application, the anti-loosening component 200 further includes two first mounting plates 211, which are respectively disposed on the top of the two clamping plates 201. The two first mounting plates 211 can be moved and adjusted in a direction that moves closer to or further away from each other. The first mounting plate 211 is provided with a plurality of first connecting holes 212.

[0039] In this embodiment, a first mounting plate 211 is provided at the top of the clamping plate 201. The first mounting plate 211 is located at the top of the cell module 300. When the cell module 300 needs to be installed inside the battery casing 100, the operator can grasp the first mounting plate 211 to move the cell module 300 into the casing 100, making transportation more convenient and suitable for situations where the space in the casing 100 is limited. At the same time, the first connecting hole 212 is located on the first mounting plate 211 at the top, near the opening at the top of the casing 100, making it easier to install and fix the cell module 300 with bolts, and improving its practicality. In addition, the two first mounting plates 211 can be moved and adjusted in a direction that moves closer or further away from each other. This can accommodate situations where there are slight errors in the size of the cell module 300 and the size of the battery casing 100, making installation more convenient.

[0040] refer to Figure 2 , Figure 3 and Figure 5As shown, in some embodiments of this application, the bottom end of the first mounting plate 211 is bent to form a third connecting plate 213. The third connecting plate 213 is provided with a plurality of waist-shaped holes 214. The waist-shaped holes 214 extend along the arrangement direction of the two clamping plates 201. Fasteners are installed between the top end of the third connecting plate 213 and the clamping plate 201. The fasteners pass through the waist-shaped holes 214.

[0041] In this embodiment, the fastener is loosened, and then the first mounting plate 211 is moved along the arrangement direction of the two clamping plates 201 so that the fastener passes through different positions in the length direction of the waist-shaped hole 214. Finally, the fastener is tightened to adjust the position of the first mounting plate 211. The structure is simple and the adjustment is convenient.

[0042] It should be noted that the two first mounting plates 211 can also be adjusted in other ways, which will not be elaborated here.

[0043] refer to Figure 2 and Figure 3 As shown, in some embodiments of this application, the anti-loosening assembly 200 further includes an insulating plate 215, which is located between two clamping plates 201. The insulating plate 215 is provided with a plurality of second sleeve holes and is respectively sleeved on a plurality of pull rods 202 through the plurality of second sleeve holes. The bottom ends of the insulating plate 215 are respectively provided with first bearing strips 216 on both sides, and the bottom ends of the two clamping plates 201 are respectively provided with second bearing strips 217 on the side that are close to each other.

[0044] In this embodiment, the insulating plate 215 is made of an electrically insulating material. When the cylindrical battery cell 301 includes two sets, and the two sets of cylindrical battery cells 301 are arranged side by side, the insulating plate 215 can be located between the two sets of cylindrical battery cells 301 to electrically insulate the two sets of cylindrical battery cells 301. This can prevent the nickel sheets on the adjacent sides of the two sets of cylindrical battery cells 301 from coming into contact with each other, thus avoiding short circuits and affecting the electrical conduction of the nickel sheets. The bottom ends of the insulating plate 215 are respectively provided with first support strips 216 on both sides, and the bottom ends of the two clamping plates 201 are respectively provided with second support strips 217 on the adjacent sides. The first support strips 216 and the second support strips 217 can cooperate to support all the cylindrical battery cells 301, preventing the cylindrical battery cells 301 from directly contacting the battery casing 100, and reducing short circuits and leakage.

[0045] It should be noted that the clamp 201 can also be made of electrical insulating material, which will not be elaborated here.

[0046] refer to Figures 6 to 8 As shown, in some embodiments of this application, the BMS mounting bracket 401 includes a second mounting plate 404, two side plates 406, and a wiring structure 407.

[0047] For example, the top and bottom surfaces of the second mounting plate 404 are respectively provided with mounting structures 405. The two mounting structures 405 are used to mount the BMS main control board 402 and the BMS slave control board 403, respectively. For example, the mounting structure 405 on the top surface of the second mounting plate 404 can be used to mount the BMS main control board 402, and the mounting structure 405 on the bottom surface of the second mounting plate 404 can be used to mount the BMS slave control board 403. Two side plates 406 are respectively connected to opposite sides of the second mounting plate 404. The two side plates 406 and the bottom surface of the second mounting plate 404 enclose a receiving space to accommodate the BMS board below the second mounting plate 404. The two side plates 406 are used to install inside the battery casing 100. The wiring structure 407 is connected to the side of the second mounting plate 404. The wiring structure 407 is provided with a wiring groove 408 that runs vertically through the top and bottom. The wiring groove 408 is used for routing the high-voltage or low-voltage lines led out from the BMS main control board 402 and the BMS slave control board 403.

[0048] In this application, the second mounting plate 404 is mounted inside the battery housing 100 via two side plates 406. The top and bottom surfaces of the second mounting plate 404 are respectively provided with mounting structures 405. The BMS main control board 402 and the BMS slave control board 403 can be mounted on the two mounting structures 405 respectively, without the need for multiple mounting brackets, making the structure simpler. In addition, the side of the second mounting plate 404 is provided with a wiring structure 407, which has a vertically penetrating wiring groove 408. The wiring groove 408 facilitates the routing of the lines led out from the BMS main control board 402 and the BMS slave control board 403, reducing messy wiring and tangling, and improving practicality.

[0049] refer to Figure 6 As shown, in some embodiments of this application, there are two wiring structures 407, which are located at both ends of the same side of the second mounting plate 404. The two wiring structures 407 are respectively used for high-voltage lines and low-voltage lines.

[0050] In this embodiment, two wiring structures 407 are provided, with a gap between them. The two wiring structures 407 are respectively used for high-voltage lines and low-voltage lines. In this way, mutual interference between high-voltage and low-voltage lines can be avoided, which would affect the function of the BMS module and thus affect the normal use of the battery.

[0051] refer to Figure 6 As shown, in some embodiments of this application, the wiring structure 407 is provided with a plurality of wiring slots 408, which are arranged along the length of the side of the second mounting plate 404 on which the wiring structure 407 is provided. In addition to being connected to each other via wiring, the BMS main control board 402 is generally also connected to the battery cell module 300 via wiring, and the BMS slave control board 403 is also connected to the battery cell module 300 via wiring.

[0052] In this embodiment, the wiring structure 407 is provided with multiple wiring grooves 408. The multiple wiring grooves 408 are arranged along the length direction of the side of the second mounting plate 404 where the wiring structure 407 is provided, which makes it more convenient to route various lines and makes wiring more convenient.

[0053] refer to Figures 6 to 8 As shown, in some embodiments of this application, the BMS mounting bracket 401 further includes a partition 409, which is located below the second mounting plate 404. The bottom end of the side plate 406 is bent to form a first connecting plate 410, which is attached to the top surface of the partition 409 and connected to the partition 409 by fasteners.

[0054] During assembly, the separator 409 is connected to the battery casing 100 and located above the cell module 300. The first connecting plate 410 at the bottom of the side plate 406 is attached to the top surface of the separator 409 and connected to the separator 409 by fasteners. This makes it easier to install the second mounting plate 404. In addition, the separator 409 can also separate the BMS module from the cell module 300, reducing the risk of leakage.

[0055] refer to Figure 7 and Figure 8 As shown, in some embodiments of this application, a wire fastener 415 is provided in the wiring trough 408. The wire fastener 415 is used to clamp the high-voltage or low-voltage wires with the inner wall of the wiring trough 408. For example, multiple wire fasteners 415 may be provided in the wiring trough 408, and the multiple wire fasteners 415 may be arranged vertically.

[0056] In this embodiment, a wire fixing buckle 415 is provided in the wiring trough 408. The wire fixing buckle 415 can cooperate with the inner wall of the wiring trough 408 to clamp the high-voltage or low-voltage wires, reduce the free shaking of the high-voltage or low-voltage wires, and make wiring more convenient.

[0057] refer to Figure 7 and Figure 8 As shown, in some embodiments of this application, the partition 409 is provided with a through groove 411, and the bottom end of the wiring structure 407 passes through the through groove 411. That is, the bottom end of the wiring structure 407 extends into the installation space of the cell module 300.

[0058] In this embodiment, this configuration makes it easier to route the high-voltage or low-voltage lines connecting the BMS main control board 402, the BMS slave control board 403, and the battery cell module 300.

[0059] refer to Figure 7 and Figure 8 As shown, in some embodiments of this application, the wiring structure 407 abuts against the inner wall of the clearance groove 411.

[0060] In this embodiment, this configuration reduces vibration of the wiring structure 407 during driving, making the wiring structure 407 connection more stable and extending its service life.
