Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to an electric pedal motor. Background Technology

[0002] With the development of the automotive industry and consumers' increasing pursuit of driving comfort and convenience, electric car pedals have been widely used as a convenient facility to assist in getting in and out of vehicles. However, existing electric car pedals face many challenges in the design and manufacturing process, especially in the connection method between the motor shaft and the rotating shaft.

[0003] Traditional connection methods typically rely on screw-locking structures, where the motor shaft is connected to the rotating shaft via a locking block and secured with screws. While this method enables mechanical transmission between the motor shaft and the rotating shaft, it results in high production costs due to the need for numerous components and a complex assembly process. Furthermore, this connection method requires high precision in the machining of parts and carries the risk of functional failure due to insufficient screw tightening or loosening of screws over long-term use. Utility Model Content

[0004] This application provides an electric pedal motor that solves the technical problem of numerous parts and complex assembly in the existing motor shaft and rotating shaft connection structure.

[0005] This application provides an electric pedal motor, comprising:

[0038] When installing motor 1, the rotating shaft 5 is installed on the base plate 3, and then the connector 7 is inserted into the rotating shaft 5 so that the first outer flat part 9 and the first inner flat part 6 are engaged. Finally, the motor shaft 2 of motor 1 is engaged with the connector 7 so that the second outer flat part 10 and the second inner flat part 8 are engaged. This reduces the number of parts used in the installation, simplifies the installation process, and reduces the risk of parts detaching.

[0039] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
