  10. The electric scooter according to claim 9, wherein the end cover (4) has a protrusion on either side in a left-right direction, and the protrusion of the end cover (4) abuts against the frame (5) to prevent the battery compartment (100) from falling out of the opening (501) downwards.

Description

FIELD The present disclosure relates to a field of battery technologies, and in particular to a battery compartment, a battery compartment assembly and an electric scooter. BACKGROUND Generally, a battery compartment of a scooter is horizontally mounted in the middle of a frame, and a top plate of the battery compartment forms a deck area. The battery compartment is complexly mounted to the frame in the related art, and the connection between the battery compartment and the frame has a low strength. When a top of the battery compartment is subjected to an overlarge impact force from a rider, the connection between the battery compartment and the frame tends to loose, and even the battery compartment falls out of an opening of the frame. CN210592288U relates to an electric scooter which includes a scooter body, a battery pack, a controller and a front vertical rod, the scooter body includes a scooter frame, a bottom box and a cover plate, a hollowed-out opening is formed in the scooter frame, the bottom box is located in the hollowed-out opening, and the top of the bottom box is opened to form an opening; the edge of the opening protrudes outwards to form a flange part, and the flange part is stopped above the frame and is fixedly connected with the frame through a fastener; the cover plate is fixed on the bottom box and seals the opening; the battery pack and the controller are accommodated in the bottom box; the front upright is pivotally connected to the front end of the vehicle body about its own axis. CN104210592A relates to an electric scooter. The electric scooter includes a frame, two front wheels mounted on the front part of the frame, a rear wheel mounted on the rear part of the frame, a driving device mounted on the frame and on one side of the rear wheel, and a power box mounted in the middle part of the frame. The battery and the controller of the electric scooter are integrated in one power box, and a motor is assembled with a gearbox, and due to high integrity, the whole electric scooter can be assembled conveniently; a region formed by the supporting pipe of the frame and a rear connecting plate is just used for containing the power box, and convenient positioning can be achieved during mounting; the gearbox is mounted in such a manner that the rear wheel can be demounted conveniently, and once a rear wheel shaft is removed, the rear wheel can be separated from the gearbox. The housing part of the electric scooter is integrally molded, so that the number of parts is reduced and the convenient mounting can be realized; a cover cap is used for covering the connection part of a head end pipe and a vertical pipe so that the scooter is smooth and attractive in overall shape. US2020398694A1 relates to an electric scooter with a top-swappable battery. The electric scooter includes a frame having an opening, and a removable deck assembly disposed in the opening. The removable deck assembly includes a deck having an upper surface and a lower surface, and a battery pack attached to the lower surface of the deck. SUMMARY The present disclosure seeks to solve at least one of the problems in the related art to some extent.
