Description

Technical Field

[0001] The utility model relates to the technical field of electric motorcycles, in particular to a battery installation structure for a small electric motorcycle. Background Art

[0002] An electric motorcycle is a type of electric vehicle that uses a battery to drive the motor. The electric drive and control system consists of a drive motor, a power supply, and a motor speed control device. The other devices of an electric motorcycle are basically the same as those of an internal combustion engine. The types are divided into electric light motorcycles and electric ordinary motorcycles according to the maximum speed or motor power.

[0003] Currently, the more popular small electric motorcycles on the market are much smaller than ordinary electric motorcycles. They are for single-person riding and relatively cheap, and are more popular among young consumer groups. However, the current small electric motorcycles, such as application number CN202321370424.8 discloses an electric motorcycle, and application number CN202121431250.2 discloses a new type of detachable battery and long-range electric motorcycle, both of which have battery components installed on the inside, but both electric motorcycles can only be installed with one battery pack, and the range is very low. They run out of power and need to be charged after a short distance. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a small electric motorcycle battery installation structure, which has a simple structure and a reasonable layout and effectively improves the endurance.

[0005] In order to solve the above problems, the utility model adopts the following technical solutions:

[0006] A battery mounting structure for a small electric motorcycle comprises an upper panel, a lower panel and front and rear baffles on both sides, the upper panel and the lower panel are connected to each other by bolts, the front and rear baffles are fixed to the front and rear ends of the upper panel and the lower panel by bolts, a transmission motor and a battery support frame are placed at the bottom end of the inner side enclosed by the upper panel, the lower panel and the front and rear baffles, a bottom battery is placed on the battery support frame, a middle partition is placed between the upper panel and the lower panel and on the bottom battery, more than three top batteries are placed on the middle partition, a top battery locking plate is placed on the top battery, and the left and right ends of the top battery locking plate are connected to the left and right ends of the middle partition by bolts.

[0007] A further technical solution is that baffle flanges are also distributed on the side ends of the front and rear baffles, and the baffle flanges on the front and rear baffles are fixedly connected to the upper enclosure plate and the lower enclosure plate by bolts.

[0008] A further technical solution is that a bracket with an "L"-shaped structure is also fixed to the left end of the battery support frame, and the bracket can hold the top battery and prevent it from moving outward, and is relatively fixed on the battery support frame.

[0009] A further technical solution is that motor protection plates are also installed on the front and rear end sides of the transmission motor to protect the transmission motor from collision and bump, and at the same time are configured to interfere with the battery support frame and the lower enclosure to limit the movement of the transmission motor.

[0010] A further technical solution is that the front and rear end sides of the middle partition are also provided with upwardly folded partition flanges for limiting the front and rear position movement of the three top batteries.

[0011] A further technical solution is that ventilation holes opening downwards are distributed on the left and right side ends of the lower enclosure plate to discharge the heat generated by the four batteries and the transmission motor inside the upper enclosure plate, the lower enclosure plate and the front and rear baffles.

[0012] The beneficial effects of the utility model are as follows: the utility model provides a battery installation structure for a small electric motorcycle, under the encirclement of an upper enclosure, a lower enclosure and front and rear baffles, at least four batteries can be arranged, and a transmission motor can be added under the premise of a reasonable layout, so that the small electric motorcycle has a longer endurance. At the same time, a top battery locking plate, a battery support frame and a middle partition are adopted, so that the four batteries can be reasonably installed inside the encirclement of the upper enclosure, the lower enclosure and the front and rear baffles and cannot move, thereby improving safety.
