Compact motor support type inner wire passing structure

Abstract

The invention provides a compact motor support type inner wire passing structure, which is characterized in that a stator and rotor module and a planet module which are in transmission connection, anda main side shaft and an auxiliary side shaft which are assembled on two sides of a hub are assembled in the hub, and the planet module is fixed between a connecting structure of the main side shaftand a stator seat. A strip-shaped support is connected between the connecting structure and the stator seat, the support passes between two adjacent planet modules of a planet gear structure, a wire passing groove along the strip-shaped structure of the support is machined in the support, and an outer wire passing hole used for enabling the stator and rotor module to be communicated with an external circuit is machined in the connecting structure. The side wire passing holes are communicated with the wire passing grooves, and circuits on the two sides of the support are connected in a penetrating mode through the side wire passing holes, the wire passing grooves and the outer wire passing holes. Due to the independent design of the support structure, circuit installation is more convenient, connection and assembly of all components are more convenient and free, and the assembly cost of a circuit can be effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of motor wire passing structure, and in particular relates to a compact motor bracket type inner wire passing structure. Background technique [0002] In the design and manufacture process of the motor, in addition to the rotor and stator structures, a deceleration structure is usually added in one piece. Depending on the deceleration structure, its application range is also varied, but the compact structure has always been the common pursuit of most integrated motors. Taking the integrated motor used on the electric bicycle as an example, in order to make the structure of the integrated motor attached to the electric bicycle more compact, various compact structural designs are often required.

Problems solved by technology

Taking the integrated motor used on the electric bicycle as an example, in order to make the integrated motor structure attached to the electric bicycle more compact, various compact structure designs are often required. Usually, due to the high-speed moving parts inside the motor, it is impossible to carry out motor fine-tuning. In this way, in the traditional integrated motor, its compact structure can usually only design the periphery of the motor, which not only makes the external structure of the motor too complicated, but also cannot fundamentally solve the compact structure design of the motor.

Especially in some motor structures, it is necessary to connect circuit structures or circuit modules on both sides of the motor. The traditional way is to connect the circuit lines through the peripheral structure of the motor, which not only makes the lines longer, but also makes the lines The structure is more complex, which not only makes the circuit shape and weight larger

This is very unfavorable for some occasions that require high size and weight, such as in the bicycle power-assisted motor structure
