[0002] The scooter battery is a container-type substance filled with electrolyte solution or metal electrodes, which acts on the scooter. It is a device that can directly convert energy into electrical energy through the chemical reaction of the substance contained inside it, thereby providing driving energy for the scooter.

[0003] When a scooter battery is used to provide electric energy for a scooter, in order to ensure that the scooter has relatively good power performance, the scooter battery needs to have good charge and discharge capabilities, and the charge and discharge performance of the scooter battery is mainly controlled by the BMS arranged inside the scooter battery. When the BMS is used to control the balanced charge and discharge of the scooter battery, since the BMS is arranged inside the scooter battery pack and is closely attached to each independent battery in the scooter battery, each battery in the scooter battery is prone to generate current flow heat, which conducts too much heat to the BMS board, and the BMS board packaged inside the battery pack is not convenient for users to repair and maintain it. Therefore, a balanced charge and discharge scooter battery is proposed to address the above problems. Utility Model Content

[0023] A balanced charge and discharge scooter battery comprises a battery pack 1 and a battery 2, wherein the battery 2 is fixedly connected to the inner side of the battery pack 1, a nickel sheet 3 is fixedly connected to the outer side of the battery 2, a connecting line 4 is fixedly connected to the outer side of the nickel sheet 3, a BMS board 5 is fixedly connected to the other end of the connecting line 4, a heat conductive sheet 6 is fixedly connected to the outer side of the BMS board 5, a transmission line 7 is fixedly connected to the outer side of the BMS board 5, a rubber sleeve 8 is slidably connected to the outer side of the transmission line 7, a box body 9 is snap-connected to the outer side of the rubber sleeve 8, a fixed shaft 10 is slidably connected to the inner side of the box body 9, a cover plate 11 is fixedly connected to the outer side of the fixed shaft 10, a rubber column 12 is fixedly connected to the outer side of the cover plate 11, a fixed block 13 is fixedly connected to the outer side of the cover plate 11, a clamping ring 14 is slidably connected to the inner side of the fixed block 13, a clamping block 15 is fixedly connected to the outer side of the box body 9, and a rubber ring 16 is provided on the inner side of the box body 9.

[0024] The box body 9 is fixedly connected to the outside of the battery pack 1, and the cover plate 11 is engaged with the inside of the box body 9. The rubber ring 16 on the inside of the box body 9 is in close contact with one side of the cover plate 11, which is convenient for shielding and sealing the upper space of the box body 9; there are 4 rubber columns 12, and the other end of the rubber column 12 is in close contact with the BMS board 5. The length of the rubber column 12 is the same as the distance from the cover plate 11 to the BMS board 5, which is convenient for fixing and restricting the BMS board 5 on the inside of the box body 9; the snap ring 14 is arranged directly above the rubber sleeve 8, and the snap ring 14 is engaged with the card block 15. One of the corners of the card block 15 is arc-shaped, which is convenient for the snap ring 14 to be engaged with the outside of the card block 15, thereby fixing and restricting the position of the cover plate 11; the heat conductive sheet 6 is arranged on the inside of the box body 9, and the side of the heat conductive sheet 6 away from the BMS board 5 is in close contact with the battery pack 1, which is convenient for conducting and dissipating the heat generated by the BMS board 5.

[0025] Working process: When the balanced charge and discharge scooter battery is used, the BMS board 5 for controlling the voltage balance inside the battery 2 is arranged on the outside of the battery pack 1 under normal use, and the BMS board 5 is protected by the box body 9 to prevent the BMS board 5 from being damaged by the outside. At the same time, the BMS board 5 arranged on the inside of the box body 9 can avoid being directly close to the battery 2, and prevent the heat generated during the charging and discharging process of the battery 2 from being conducted to the BMS board 5, affecting the normal working performance of the BMS board 5. The BMS board 5 on the inside of the box body 9 is stably restricted to the inside of the box body 9 by the cover plate 11 and the rubber column 12 fixedly connected thereto, and the outside of the cover plate 11 is stably engaged with the block 15 through the engagement of the snap ring 14, so that the cover plate 11 is stably engaged with the inside of the box body 9. When the BMS board 5 on the inside of the box body 9 needs to be repaired and maintained, the snap ring 14 can be moved to make the snap ring 14 break away from its engagement restriction on the block 15 and make a circular movement inside the fixed block 13. When the clamping ring 14 is lifted, the cover plate 11 can be driven by the fixing block 13 to rotate inside the box body 9 with the axis of the fixed shaft 10 as the center of the circle, so as to expose the opening position at the upper end of the box body 9, which is convenient for the operator to repair and maintain the BMS board 5 placed inside the box body 9, and effectively avoids the cumbersome process of the operator disassembling the battery pack 1 to take out the BMS board 5. After the operator has repaired and maintained the BMS board 5 inside the box body 9, the cover plate 11 can be re-engaged on the inside of the box body 9 by reverse operation. The cover plate 11 is engaged inside the box body 9 and can squeeze the rubber ring 16 arranged on the inside of the box body 9, so that the cover plate 11 has a better sealing and engaging effect on the box body 9, reducing the probability of the BMS board 5 inside the box body 9 being damaged by the outside. This device greatly facilitates the operator to repair and maintain the BMS board 5, and effectively avoids the heat generated by the current flow of each battery 2 in the scooter battery, which conducts too much heat to the BMS board 5 and affects the normal operation of the BMS board 5.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
