Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to an integrated fastening connection structure and an electric motorcycle battery. Background Technology

[0002] The lithium battery industry is booming, and lithium batteries are being used more and more widely not only in electric vehicles and electric bicycles, but also in electric motorcycles.

[0003] For electric motorcycles, due to the strong acceleration / braking impact and significant road vibration during operation, the lithium batteries used in electric motorcycles require high structural strength and anti-slip properties. Otherwise, insecure fixing can cause displacement, leading to wire harness breakage or short circuits. For example, the utility model patent application with application number CN202021829283.8 uses the thread on the module tensioning screw and the locking nut to lock and fix multiple battery modules, which improves the structural strength of the battery. However, the upper and lower battery covers still need to be connected with screws, leaving screw mounting holes exposed on the outer surface of the battery, affecting aesthetics. In addition, the anti-slip effect of this battery is poor. Another example is the utility model patent application with application number CN202222325710.4, where a connecting rod passes through multiple cell modules, with one end of the connecting rod extending to fix the connecting cover. This effectively improves the structural strength of the battery, but one side still has exposed connecting rod mounting holes, affecting aesthetics. In addition, the anti-slip effect of this battery is also poor. Utility Model Content

The locking connection assembly 400 includes a stop 410 and a fastener 420. The stop 410 is disposed at the anti-slip decorative area 301 and abuts against the side of the lower cover 300 away from the cylindrical shell 100, and the side of the stop 410 near the cylindrical shell 100 is connected to the fastener 420. The fastener 420 passes through the lower cover 300, and the end of the fastener 420 away from the stop 410 is fastened to the side of the upper cover 200 near the cylindrical shell 100. The anti-slip decorative area 301 is configured to allow the anti-slip decorative element 500 to be attached and to allow the anti-slip decorative element 500 to contact the vehicle body, with the fastener 420 located on the side of the anti-slip decorative element 500 near the lower cover 300.

[0042] The aforementioned integrated fastening connection structure 10 allows the stop member 410 to be located at the anti-slip decorative area 301 and abut against the side of the lower cover 300 away from the cylindrical shell 100. The side of the stop member 410 closest to the cylindrical shell 100 is connected to the fastener 420, thus enabling the fastener 420 to limit and fix the lower cover 300 through the stop member 410. Furthermore, the fastener 420 passes through the lower cover 300, and the end of the fastener 420 away from the stop member 410 is fastened to the side of the upper cover 200 closest to the cylindrical shell 100. This effectively achieves the integration of the upper cover 200, lower cover 300, and cylindrical shell 100. The tight connection effectively ensures the structural strength of the battery. The anti-slip decorative area 301 on the lower cover 300 is configured to accommodate the anti-slip decorative element 500 and allow it to contact the vehicle body. Furthermore, the fastener 420 is positioned on the side of the anti-slip decorative element 500 closest to the lower cover 300. This ensures that the anti-slip decorative element 500 not only provides anti-slip protection for the battery but also decorates the battery and conceals the exposed mounting holes of the locking connection assembly 400, effectively ensuring the battery's anti-slip effect. This significantly improves the battery's secure fixation and enhances its aesthetics.

[0043] Please refer to the following: Figures 4 to 6In one embodiment, the upper cover 200 has a drilled and tapped threaded hole 201 on the side near the cylindrical shell 100.

The fastener 420 of each locking connection assembly 400 is located on the side of the anti-slip decorative member 500 near the lower cover 300, further improving the reliability of the integral fastening connection of the upper cover 200, lower cover 300, and shell 100, thereby further improving the battery's secure fixing.

[0048] In one embodiment, the fastener is screwed onto the lower cover. It can be understood that when the fastener is inserted into the lower cover, it is connected to the lower cover via a threaded connection. That is, the fastener achieves an integrated fastening connection between the upper cover, lower cover, and casing by threading onto both the upper and lower covers respectively, effectively improving the reliability of the fastener's threaded connection and further enhancing the battery's secure fixation.

[0049] Please refer to the following: Figure 2, Figures 4 to 6 In one embodiment, the cylindrical shell 100 is provided with a through-hole area 101, the extension direction of the through-hole area 101 being the same as the length direction of the cylindrical shell 100. The fastener 420 passes through the through-hole area 101 and is connected to the cylindrical shell 100. It can be understood that by providing the through-hole area 101 extending along its own length direction on the cylindrical shell 100, the fastener 420 passes through the through-hole area 101, thereby achieving the positioning and fixing of the cylindrical shell 100 by the fastener 420, improving the alignment accuracy of the fastening connection between the cylindrical shell 100 and the upper cover 200 and the lower cover 300 respectively, and also improving the reliability of the limiting and fixing of the cylindrical shell 100 at the upper cover 200 and the lower cover 300.

[0050] In one embodiment, the through-hole area is a through-hole, which better ensures the effective positioning and fixation of the fastener on the shell.
