[0002] When an automotive battery is working, a large amount of heat is generated during energy conversion, which will cause the battery to generate heat. In order to prevent the battery from being damaged by high temperature, a water-cooling method is used to protect and cool the battery. Since the water-cooling effect always exists, in winter, the external temperature is already low, and due to the water-cooling effect, the battery temperature will be reduced. The low temperature will affect the chemical reaction rate of the battery, resulting in battery attenuation, making the battery unable to turn off the water-cooling according to the external air temperature, which affects the operation of the battery. Content of the Utility Model

[0018] Embodiment 1: Refer to Figures 1 - 3 , a water-cooled protective vehicle battery, including an outer shell 1, heat dissipation ribs 2 fixedly connected to the outer shell 1, an internal battery cell 13 arranged in the outer shell 1, a cavity 12 arranged on the outer shell 1, and water filled in the cavity 12, and the water plays a role in cooling and dissipating heat from the internal battery cell 13.
[0019] A connecting pipe 4 is connected to the cavity 12 in a communicating manner. A valve 5 is arranged on the connecting pipe 4. A connecting cylinder 6 is connected to the connecting pipe 4 in a communicating manner. The connecting cylinder 6 is fixedly connected to the outer shell 1. A piston 16 is abutted inside the connecting cylinder 6. A connecting rod 15 is fixedly connected to the piston 16. A moving part 11 is fixedly connected to the connecting rod 15. The moving part 11 is fixed by a fixing mechanism. A support plate 3 is fixedly connected to the outer shell 1. When battery heat dissipation is required, the water in the cavity 12 absorbs heat to cool the internal battery cell 13. When heat dissipation is not required in winter, by pulling the connecting rod 15 to move, the water in the cavity 12 is pumped into the connecting cylinder 6, so that there is no water in the cavity 12 and cooling and heat dissipation cannot be carried out, so as to turn off the water cooling according to the external temperature environment, which is beneficial to the normal operation of the battery.
[0020] The fixing mechanism includes a threaded rod 7. A threaded hole 14 is formed in the connecting rod 15. The threaded hole 14 is threadedly connected to the threaded rod 7. The threaded rod 7 threadedly penetrates through the moving part 11. The moving part 11 is limited by a limiting mechanism. The threaded rod 7 is rotatably connected to a connecting ear 10 through a bearing. The connecting ear 10 is fixedly connected to the outer shell 1. By rotating the threaded rod 7, the position of the threaded rod 7 in the threaded hole is adjusted, so as to adjust the position of the piston 16, and water is filled into the cavity 12 or the water in the cavity is pumped out.
[0021] When it is necessary to turn off the water cooling: by rotating the threaded rod 7, the position of the threaded rod 7 in the threaded hole is adjusted, the piston 16 is pulled, so that the water in the cavity 12 enters the connecting cylinder 6, and then the valve 5 is closed. When it is necessary to turn it on, rotate the threaded rod 7, the piston 16 is pushed, and the water is pushed back into the cavity 12.
[0022] Embodiment 2: Refer to Figures 1 - 3 , as another preferred embodiment of the present invention, on the basis of Embodiment 1, the limiting mechanism includes a fixing ear 9. A limiting post 8 is fixedly connected to the fixing ear 9. The limiting post 8 penetrates through the moving part 11.
