Description

Technical Field

[0001] This utility model relates to the field of electric vehicle technology, and in particular to a waterproof battery box structure for two-wheeled electric vehicles. Background Technology

[0002] In recent years, with the rapid development of lithium-ion battery technology, lithium-ion batteries have been replacing traditional lead-acid batteries in various power supply fields, such as electric vehicles. Compared with traditional lead-acid batteries, lithium-ion batteries have advantages such as high energy density, small size, light weight, long service life, and wide operating temperature range. Currently, the process of lithium-ion batteries is becoming increasingly mature, and the cost is gradually becoming more reasonable, making them a mainstream high-end starting power solution. However, when electric vehicles are driven in the rain, the road surface is prone to water accumulation. When riding electric vehicles in water, the battery box with a low sealing level is not waterproof, which makes it easy for water to enter the battery box. Moreover, after being soaked for a long time, the battery will be damaged and corroded, shortening the service life of the electric vehicle.

[0003] Chinese utility model patent application number 202420177395.1 discloses an electric vehicle battery box and an electric vehicle. The battery box includes a main body and a heat dissipation assembly. The main body includes a box and a cover, with the cover fixedly mounted on the top of the box. Inside the box is a battery placement box with an open top. Cavities are provided between the battery placement box and the inner wall of the box, as well as between adjacent battery placement boxes. Air inlets are provided on both sides of the box. A cover with an open top is fixed to the bottom of the cover, with a sealing block at the bottom of the cover that inserts into the open top of the battery placement box. Connecting holes are provided on both sides of the cover, and an exhaust vent is provided on the top of the cover. However, this type of electric vehicle battery box uses a sealed structure to achieve waterproofing. While this effectively improves the sealing and waterproofing of the battery box, it affects the heat dissipation of the battery, leading to increased battery operating temperature and impacting battery performance. Furthermore, prolonged exposure to high temperatures can shorten battery life. Summary of the Invention

The waterproof top plate 4, through its arc-shaped streamlined structure, guides water to achieve a waterproof function. A schematic diagram of the waterproof mechanism structure of this utility model is shown below. Figure 2 As shown.

[0020] It also includes mounting blocks 5 and mounting screws 6. There are two sets of mounting blocks 5, which are symmetrically arranged at both ends of the waterproof substrate 2 and fixedly connected to the waterproof substrate 2. The mounting screws 6 are arranged in the middle of the mounting blocks 5 and pass through the mounting blocks 5. The mounting screws 6 are threadedly connected to the housing 1. The waterproof substrate 2 is fixedly connected to the housing 1 through the mounting blocks 5 and the mounting screws 6.

The heat dissipation through holes 12 are located on the upper part of one side of the casing 1, corresponding to the heat dissipation fan 11, and penetrate through the casing 1. The heat dissipation through holes 12 consist of several arrayed through holes. On one side of the casing 1, two sets of ventilation holes are arranged side by side at intervals corresponding to the heat dissipation through holes 12.

[0025] Working principle: The battery pack 8 is positioned between two sets of mounting end blocks 7 and installed and positioned using the mounting positioning bracket 9. The waterproof mechanism is then assembled onto the housing 1 using mounting screws 6, thus completing the assembly of the battery box. After that, the housing 1 is installed inside the frame of the electric vehicle, thus completing the installation of the battery box. During operation, the cooling fan 11 works in conjunction with the cooling through holes 12 to dissipate heat from the battery pack 8, ensuring the working condition of the battery pack 8. In the assembled state, when water flows into the electric vehicle through the gaps in the frame of the electric vehicle, the waterproof top plate 4 at the top of the battery box guides the water to achieve water drainage, preventing water from entering the battery box and thus achieving the purpose of waterproofing.
