Description

Technical Field

[0001] The utility model relates to the field of electric vehicles, and in particular to a motor placement device for a two-wheeled electric vehicle. Background Art

[0002] Electric vehicle motors vary in form factor depending on their operating environment and frequency. Each motor type has distinct characteristics. Currently, permanent magnet DC motors are the most commonly used in electric vehicle motors. Electric vehicle motors can be categorized by the type of power supply: brushed and brushless. Based on the mechanical structure of the motor assembly, they are generally divided into "geared" (high-speed motors requiring gear reduction) and "gearless" (motor torque output without any gear reduction). The drive motors used in electric vehicles differ from conventional industrial motors. They typically require frequent starting / stopping, acceleration / deceleration, high torque at low speeds or when climbing grades, low torque at high speeds, and a wide speed range. Industrial motors, on the other hand, are typically optimized for their rated operating point. Therefore, electric vehicle drive motors are unique and should be classified in their own category.

[0003] During the assembly and production process of electric vehicles, various components need to be placed. For example, after the motor is installed on the wheel hub, it needs to be placed on a rack to prevent the motor from rolling around. In the authorized Chinese utility model patent "Announcement No.: CN217731244U, Name: A Motor Mounting and Placing Platform", a limit groove is set on the platform body so that the motor can be placed in the limit groove to prevent the motor from moving relative to the motor. A second connecting piece is then set on this basis, and the first connecting piece of the motor itself is used to cooperate with the second connecting piece so that the motor can be fixed in the limit groove and will not rotate relative to the limit groove, thereby achieving stable placement of the motor and facilitating subsequent operation procedures. However, due to the different models of electric vehicles, the models of their wheel hubs are also different. The above application can only fix a single model of wheel hub, resulting in a limited scope of application of the placement device, which affects the placement of the motor. Utility Model Content
