Problems solved by technology
[0002] The existing electric vehicles are usually two-speed electric vehicles, and the two-speed electric vehicles usually have the following problems: 1. The conversion is not stable enough and comfortable; 2. The motor power is insufficient; 3. The working efficiency of the motor is low; 4. A single relay cannot satisfy multiple gears. The needs of switching; how to solve the above problems become the subject of research by those skilled in the art

The invention provides a novel electrocar. The novel electrocar comprises a three-speed motor and a three-gear relay. A coil of the motor comprises three gears, namely a high-speed gear, a middle-speed gear and a low-speed gear. The three-gear relay comprises two independent relays integrated inside a shell, one of the two relays is provided with a common end and the other is not provided with the common end, and a normally closed contact of the former relay is connected with a movable contact of the other relay. By adopting the three-speed motor and the three-gear relay to control the speed of the electrocar, the rotative speed difference among the three gears is small, and the shifting effect is stable and comfortable. Due to the fact the three-gear relay adopts two existing relays which are integrated inside the shell, one common end is saved, and the wire arrangement is well-ordered and well-organized. Compared with the two independent relays, the space is saved, and the wiring is convenient during the utilization.
Description
technical field [0001] The invention belongs to the technical field of electric vehicles and relates to a novel electric vehicle. Background technique [0002] The existing electric vehicles are usually two-speed electric vehicles, and the two-speed electric vehicles usually have the following problems: 1. The conversion is not stable enough and comfortable; 2. The motor power is insufficient; 3. The working efficiency of the motor is low; 4. A single relay cannot satisfy multiple gears. The need for handover; how to solve the above problems has become a research topic for those skilled in the art. Contents of the invention [0003] The problem to be solved by the present invention is to provide a novel electric vehicle with smooth and comfortable switching. [0004] In order to solve the above problems, the technical solution adopted by the present invention is: a new type of electric vehicle, including a three-speed motor and a three-speed relay; [0005] The three-spe...
