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.

[0019] Reference Figures 1 to 4 As shown, this utility model provides a waterproof testing device for electric bicycle battery packs, including: a water immersion tank 1 and a waterproof testing instrument 5. The waterproof testing instrument 5 is supported at the upper end of the water immersion tank 1 by a fixing frame 11.

[0020] The inner wall of the immersion pool 1 is supported by a support base 13. A clamp 2 is connected to the side end of the storage frame 2 by an adjusting stud 21. A rotating top plate 3 is fixedly connected to the upper end of the storage frame 2. A motor 31 is connected to the upper surface of the rotating top plate 3 by a rotating shaft 35. A symmetrical air supply slot 36 is provided on the surface of the rotating top plate 3. A powerful fan 34 is installed on the upper end of the air supply slot 36.

[0021] First, the electric bicycle battery pack to be tested is clamped in the storage frame 2 and lowered into the immersion tank 1. Water is poured into the immersion tank 1, and after the electric bicycle battery pack has been soaked for a period of time, the water in the immersion tank 1 is drained. The motor 31 drives the storage frame 2 to rotate, which spins the water off the surface of the electric bicycle battery pack. At the same time, a powerful fan 34 draws outside air to the surface of the electric bicycle battery pack to accelerate air circulation. After drying, the electric bicycle battery pack is moved up, and the waterproof testing instrument 5 is used to test the water-soaked electric bicycle battery pack to obtain the waterproof status of the electric bicycle battery pack.

[0028] In this embodiment, a fixing plate 32 is provided on the lower surface of the motor 31, and the upper end of the fixing plate 32 is connected to the fixing frame 11 through a hydraulic column 33. A rotating top plate 3 is attached to the lower surface of the fixing plate 32, and two sets of powerful fans 34 are embedded in the surface of the fixing plate 32.

[0029] In a preferred embodiment, the hydraulic column 33 is used to pull the rotating top plate 3, which is connected to the storage frame plate 2, out of the immersion tank 1. Two sets of powerful fans 34 draw outside air into the surface of the electric bicycle battery pack in the immersion tank 1, accelerating the evaporation of moisture from the surface of the electric bicycle battery pack.

[0030] This utility model's waterproof testing device for electric bicycle battery packs effectively solves the problem in existing technologies where water droplets on the surface of the battery pack after pumping water can easily affect the normal operation of waterproof testing instruments. It realizes a waterproof testing device with a rapid drying function, which facilitates the evaporation of moisture on the surface of the electric bicycle battery pack after immersion in water, avoids the influence of heating drying methods on the test results of electric bicycle batteries, ensures the dryness of the electric bicycle battery surface during testing, improves the practicality of immersion-type waterproof testing devices, and is suitable for waterproof testing devices for electric bicycle battery packs.
