Technical Field

[0001] This utility model relates to the field of battery pack wiring technology, specifically a convenient wiring structure for an electric motorcycle battery pack. Background Technology

[0002] The battery pack is the core component of an electric motorcycle's power system, typically consisting of multiple lithium-ion battery cells connected in series or parallel. For ease of installation, maintenance, and battery replacement, the battery pack's wiring structure needs to be simple, reliable, and convenient.

[0003] The existing patent with publication number CN211828992U proposes a convenient wiring lithium-ion battery pack. The device does not require repeated flipping of the battery pack body. Instead, the bent welding piece is covered with a cover plate, and the protection board cable connector and the bent welding piece can be welded in the operation port of the cover plate, which can quickly position the device. At the same time, each operation port is also marked with a welding sequence, which reduces the difficulty of wiring.

[0004] However, when the device connects the two sets of battery blocks through the connecting wire, it cannot achieve quick guiding and docking between the connecting plates at both ends of the connecting wire and the docking device. When using screws to fix the connecting plates, quick connection cannot be achieved. Utility Model Content

[0005] The purpose of this utility model is to provide a convenient wiring structure for electric motorcycle battery packs, so as to solve the problem that existing devices cannot achieve quick guiding and docking of the connecting plates at both ends of the connecting wire with the docking device, and cannot achieve quick connection when using screws to fix the connecting plates.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a convenient wiring structure for an electric motorcycle battery pack, comprising a housing, a top cover fixedly mounted on the upper end of the housing, a groove inside the housing, a battery block disposed inside the groove, a connecting wire mounted on the upper end of the battery block, connecting plates fixedly mounted on both ends of the connecting wire, a connector fixedly mounted on the upper end of the battery block, a guide structure between the battery block and the connecting plate, the guide structure comprising two fixing members fixedly mounted on the upper end of the battery block and a snap-fit ​​member fixedly mounted on the lower end of the connecting plate, and a screw disposed inside the connecting plate, the screw output end entering the connector.

[0007] Preferably, a fixing plate is fixedly provided on both sides of the lower end of the upper cover, and a fixing groove is fixedly provided on the upper end of the upper cover located at the lower end of the fixing plate.

[0008] Preferably, the upper cover has a bolt inside, and a threaded hole is provided at the upper end of the housing located below the bolt.

[0009] Preferably, a fixing cover is fixedly provided on the upper end of the connecting plate located on the outer wall of the screw.

[0010] Preferably, a rubber strip is fixedly provided at the upper end of the connecting plate, and a rubber cap is fixedly provided at the upper end of the rubber strip.

[0011] Preferably, a sealing gasket is fixedly provided at the upper end of the housing.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1) By setting a guide structure, when connecting two sets of battery blocks through connecting wires, the fasteners and snap-fit ​​components can be used to quickly assemble the battery blocks and connecting plates, and the installation efficiency of fixing the battery blocks and connecting plates can be accelerated when installing screws.

[0014] 2) By setting a fixing plate and fixing groove, after the top cover and the shell are closed, the fixing plate enters the fixing groove, thereby ensuring the stability of the installation of the top cover and the shell and enhancing the overall pressure resistance.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Combination Figures 1-4 A convenient wiring structure for an electric motorcycle battery pack includes a housing 1, a top cover 2 fixedly mounted on the upper end of the housing 1, a groove 3 inside the housing 1, a battery block 4 inside the groove 3, a connecting wire 5 on the upper end of the battery block 4, connecting plates 6 fixedly mounted at both ends of the connecting wire 5, a connector 7 fixedly mounted on the upper end of the battery block 4, a guide structure 8 between the battery block 4 and the connecting plate 6, the guide structure 8 including two fixing parts 9 fixedly mounted on the upper end of the battery block 4 and a snap-fit ​​part 10 fixedly mounted on the lower end of the connecting plate 6, and a screw 132 inside the connecting plate 6, the output end of the screw 132 entering the interior of the connector 7.

[0023] See Figure 1 , Figure 2 and Figure 4 Furthermore, the upper cover 2 is provided with a bolt 16 inside, and the upper end of the housing 1 located at the lower end of the bolt 16 is provided with a threaded hole. A fixing cover 11 is fixedly provided on the upper end of the connecting plate 6 located on the outer wall of the screw 132. A rubber strip 12 is fixedly provided on the upper end of the connecting plate 6. A rubber cap 13 is fixedly provided on the upper end of the rubber strip 12. A sealing gasket 131 is fixedly provided on the upper end of the housing 1.

[0024] Specifically, bolt 16 passes through the upper cover 2 and connects to the threaded hole to achieve the fixed installation of the upper cover 2. The fixing cover 11 is used to fix the rubber cap 13, thereby protecting the screw 132. The sealing gasket 131 is used to ensure the stable connection between the upper cover 2 and the housing 1.

[0025] Example 2

[0026] See Figure 2 Furthermore, based on Embodiment 1, a fixing plate 14 is fixedly provided on both sides of the lower end of the upper cover 2, and a fixing groove 15 is fixedly provided on the upper end of the upper cover 2 located at the lower end of the fixing plate 14.

[0027] Specifically, after the fixing plate 14 enters the fixing groove 15, it strengthens the stable connection between the top cover 2 and the housing 1.

[0028] In actual operation, when it is necessary to connect the two battery blocks 4 of the motorcycle battery, the snap-fit ​​10 at the lower end of the connecting plate 6 is snapped into the reserved groove at the upper end of the fixing part 9. At this time, the round hole inside the connecting plate 6 is precisely connected with the docking device 7 to achieve the guiding installation of the connecting plate 6.

[0029] Install screw 132 into the round hole inside the connecting plate 6, rotate it into the connector 7, thereby realizing the installation of the connecting wire 5. Flip the rubber cap 13 so that the rubber cap 13 is fitted on the outer wall of the fixing cover 11 to prevent dust from damaging screw 132.

[0030] After the fixing plate 14 at the lower end of the upper cover 2 is inserted into the fixing groove 15, the bolt 16 is passed through the upper cover 2 and enters the threaded hole to achieve a stable installation of the upper cover 2 and the housing 1.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
