Description

Technical Field

[0001] This utility model relates to the field of lithium battery casing technology, specifically a novel fast-charging universal lithium battery casing for two-wheeled vehicles. Background Technology

[0002] With changes in urban traffic conditions and increasingly stringent environmental requirements, new energy two-wheeled vehicles have become an important trend in future travel. Two-wheeled electric vehicles, especially electric bicycles and electric motorcycles, have been widely used due to their green, environmentally friendly, low-energy consumption, convenient, and efficient characteristics. Electric two-wheelers are powered by lithium batteries, which, as the most widely used power batteries on the market, have advantages such as high energy density, light weight, and long cycle life. With continuous technological advancements, the charging speed and battery life of lithium batteries have become key focuses in the industry, especially in the application of "fast charging" technology. The emergence of new fast charging technologies requires lithium batteries to be able to complete charging in a short time while ensuring safety and a long battery life.

[0003] The design of a lithium battery casing directly affects the battery's safety, heat dissipation performance, structural strength, and lifespan. Traditional lithium battery casings are mostly made of aluminum alloy or plastic. While these materials can meet basic safety requirements to a certain extent, they may experience poor heat dissipation and structural deformation under the high temperatures and currents of fast charging, thus affecting the battery's charging efficiency and lifespan. Furthermore, lithium battery casings are typically fixed structures, making installation and removal inconvenient. No solutions have yet been proposed to address these technical issues. Utility Model Content

[0004] In response to the problems in related technologies, this utility model proposes a novel fast-charging universal lithium battery casing for two-wheeled vehicles to overcome the aforementioned technical problems in existing related technologies. The purpose of this utility model is to facilitate the installation and removal of the lithium battery inside the casing, which is beneficial for later maintenance and replacement, effectively improves the heat dissipation generated by the battery during charging, avoids overheating, and improves the overall charging efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel fast-charging universal lithium battery housing for two-wheeled vehicles, comprising an outer shell, a top cover provided on the top of the outer shell, cooling fans provided on both sides of the outer shell, the outer shell and the top cover being connected by a connecting mechanism, a U-shaped groove being provided on the top of the outer shell, and a U-shaped locking block being provided at the bottom of the top cover;

[0006] The connecting mechanism includes a spring, a rubber column, a snap-fit ​​plate, a moving rod, and a support. The support is fixedly installed on the outer shell and has an opening. The two ends of the spring and the rubber column are fixedly connected to the opening and the snap-fit ​​plate, respectively. The spring is sleeved on the outer surface of the rubber column. Several moving rods are provided, and one end of each rod is fixedly connected to the bottom of the snap-fit ​​plate. The top cover has a snap-fit ​​groove.

[0007] Preferably, a pressure pad is provided inside the groove, and the pressure pad is made of rubber material.

[0008] Preferably, a handle is movably connected at the top center of the top cover.

[0009] Preferably, the outer shell has an internal cavity, and the cavity is further provided with heat dissipation fins.

[0010] Preferably, the connecting mechanism is provided in two sets, and is located on both sides of the outer shell respectively.

[0011] Preferably, the outer shell and top cover are made of aluminum alloy.

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

[0013] (1) This utility model is a new type of fast-charging universal lithium battery housing for two-wheeled vehicles. By setting a connecting mechanism, when installing the top cover, first manually press the moving rod at the bottom of the snap-fit ​​plate to move the snap-fit ​​plate to one side of the outer shell. At the same time, the spring and rubber column are compressed, and the top cover is placed on the outer shell.

[0014] (2) This utility model is a new type of fast-charging universal lithium battery shell for two-wheeled vehicles. By setting a cooling fan, the heat generated by the lithium battery inside the shell during the charging process can be effectively dissipated. The heat dissipation fins are attached to the outer surface of the lithium battery, which can effectively accelerate the dissipation of the lithium battery heat, avoid overheating, ensure that the battery can continuously exchange heat during the charging process, avoid the decrease in charging speed due to excessive temperature, improve the overall charging efficiency, prevent the internal temperature of the battery from being too high, extend the battery life, and ensure the safety of the charging process.

A U-shaped groove 4 is opened on the top of the outer shell 1, and a U-shaped locking block 5 is provided on the bottom of the top cover 2. Specifically, the U-shaped groove 4 and the U-shaped locking block 5 cooperate to improve the stability of the connection between the outer shell 1 and the top cover 2.

[0023] The connecting mechanism includes a spring 6, a rubber column 7, a snap-fit ​​plate 8, a moving rod 9, and a support 10. The support 10 is fixedly installed on the outer shell 1 and has an opening 11. The two ends of the spring 6 and the rubber column 7 are fixedly connected to the opening 11 and the snap-fit ​​plate 8, respectively. The spring 6 is sleeved on the outer surface of the rubber column 7. Several moving rods 9 are provided, and one end of each is fixedly connected to the bottom of the snap-fit ​​plate 8. The top cover 2 has a snap-fit ​​groove 12. Specifically, the support 10 provides support. When installing the top cover 2 onto the outer shell 1, first manually press the moving rod 9 at the bottom of the snap-fit ​​plate 8 to move the snap-fit ​​plate 8 to one side of the outer shell 1. At the same time, the spring 6 and the rubber column 7 are compressed, placing the top cover 2 onto the outer shell 1. Release the moving rod 9, and under the action of the spring 6 and the rubber column 7, the snap-fit ​​plate 8 moves into the snap-fit ​​groove 12 of the top cover 2, thus completing the installation. Disassembly can be performed according to the actual operation.

[0024] Please see Figure 2-3As shown, further, a pressure pad 13 is provided inside the groove 4, and the pressure pad 13 is made of rubber material.

[0025] In this embodiment, the sealing between the outer shell 1 and the top cover 2 is effectively improved by setting the compression pad 13.

[0026] Please see Figure 1-2 As shown, a handle 14 is movably connected to the top center of the top cover 2.

[0027] In this embodiment, a handle 14 is provided to facilitate the taking out of the outer shell 1.

[0028] Please see Figure 2 As shown, the outer casing 1 is further provided with a receiving cavity, and the receiving cavity is also provided with heat dissipation fins 15.
