Technical Field

[0001] The utility model relates to the technical field of electric scooters, in particular to an electric scooter with a detachable battery. Background Art

[0002] Electric scooters are a kind of portable means of transportation, which have become increasingly popular in short-distance urban travel in recent years. They are powered by electricity and have the advantages of being light, fast and environmentally friendly. They have gradually become an important means of transportation in people's daily lives. Compared with traditional human-powered skateboards, the main difference between electric scooters is that they are equipped with electric drive kits. According to different driving modes, electric scooters can be divided into two types: two-wheel drive and single-wheel drive. The most common transmission modes are hub motors and belt drives.

[0003] The core components of an electric scooter include a motor, battery, controller and frame. Among them, the motor is the key component of power output, while the battery provides the necessary electrical energy. Modern electric scooters mostly use lithium batteries because of their high energy density, light weight and long life. The controller is responsible for adjusting the working state of the motor to ensure the stable operation of the scooter under different working conditions. The advantage of an electric scooter is its convenient and fast use, which can save a lot of social resources. Its maximum speed can reach 32 kilometers per hour, and its weight is usually between 6 and 15 kilograms, which makes it very easy to carry and store. Its control method is similar to that of a traditional electric bicycle and is easy to use. Many electric scooters are also equipped with a detachable and foldable seat, which further enhances portability.

[0004] The battery of a common electric scooter is placed in a battery slot on the top of the body, and the battery is fixed by a cover plate and a limit block so that the battery is bound to the body. However, since the user usually stands on the top of the body and the wheels support the body at both ends of the body, the body is prone to bending. The body is a metal structure and bending deformation can be restored, but the battery shell is a plastic structure and is prone to cracking after bending, which reduces the battery life. In view of this, the present application proposes an electric scooter with a detachable battery. Utility Model Content
