Description

Technical Field

[0001] The present invention relates to the technical field of electric vehicles, in particular to a multi-purpose four-wheeled electric scooter for both passengers and cargo. Background Art

[0002] In an era of environmental protection and green transportation, electric vehicles are widely used in small and medium-sized cities and rural areas due to their simple structure, low price, and ease of use. They are suitable for carrying daily necessities over short distances. Furthermore, they are low in operating and maintenance costs, consume no gasoline, and do not emit polluting exhaust gases. Electric vehicles are generally referred to as electric vehicles that use batteries as their energy source and convert electrical energy into mechanical motion through components such as controllers and motors, controlling the current flow to change speed.

[0003] Electric vehicles can be divided into the following categories according to the number of tires and structural type: electric bicycles, electric unicycles, electric four-wheeled vehicles, etc. In recent years, new energy electric vehicles have become popular, and four-wheeled electric vehicles have developed rapidly.

[0004] The patent application number CN201420863715.5 provides a chassis structure for an electric vehicle that can be used for both passenger and cargo. Since a rear mounting frame is provided for mounting passenger seats or cargo boxes, when a seat is mounted on the rear mounting frame, the chassis becomes a chassis for an electric vehicle for carrying passengers; when a cargo box is mounted on the rear mounting frame, the chassis becomes a chassis for an electric vehicle for carrying cargo.

[0005] Although this technical solution can improve the functionality of four-wheeled electric vehicles to a certain extent and provide a certain amount of cargo storage space while meeting the needs of carrying passengers, it still has certain shortcomings: the cargo space and seats need to be disassembled and assembled cumbersomely when changing, which is cumbersome to operate and inconvenient for users, and foreign objects are easily mixed into the installation position, causing inconvenience in installation.

[0006] The patent with application number CN201921473499.2 provides a new type of electric sightseeing vehicle. By setting up a passenger and cargo seat, a passenger and cargo seat is designed at the rear of the electric vehicle when in use, which effectively avoids the situation where the sightseeing vehicle is limited in the unloading position when there is a lot of cargo, which is not conducive to loading cargo. When carrying passengers, the original position of the passenger and cargo seat is that the top surface of the main board is in contact with the upper surface of the support board. Tourists sit on the main board pad for sightseeing, the pedals make it convenient for tourists to get on and off, the left and right handrails are convenient for protecting the safety of tourists, and the backrest allows tourists to lie down for sightseeing.

[0007] Although this technical solution can improve the functionality of four-wheeled electric vehicles to a certain extent and provide a certain amount of cargo storage space while meeting the needs of carrying passengers, it still has certain shortcomings: the cargo space has poor hidden storage capabilities and occupies a certain amount of space when not in use, affecting the use of the electric vehicle.
