TECHNICAL FIELD

[0001] The utility model relates to the technical field of wheel hub motor especially relates to a motor wire package parallel structure. BACKGROUND

[0002] Electric vehicle wheel hub motor is one of the core components of electric vehicle, its performance directly influences the electric vehicle's power, endurance and other key indicators. In the wheel hub motor, the wrapping and parallel of coil wire plays a crucial role. Coil wire is usually composed of enameled wire, and these enameled wires need to be reasonably parallel to ensure the normal operation of the motor.

[0003] The wrapping and parallel of coil wire mainly combines multiple enameled wires together in a certain way to form a specific circuit connection. Different parallel methods will affect the electrical performance of the motor, such as resistance, inductance and other parameters, and thus affect the output power, efficiency and other parameters of the motor. Common parallel methods include single parallel, double parallel, four parallel and so on. During parallel operation, it is necessary to ensure that the connection between enameled wires is firm and reliable to avoid problems such as looseness and poor contact, so as to ensure stable transmission of current. At the same time, in order to prevent enameled wires from being affected by external factors such as vibration and friction during motor operation, some insulating materials are usually used to wrap the parallel coil wire to improve the safety and reliability of the motor.

[0004] In the actual production and maintenance process of electric vehicle wheel hub motor, the existing technology has some problems in the wrapping and parallel of coil wire. In the parallel operation process, the traditional method usually uses U-shaped block compression and screw fastening. This method has many disadvantages in practical application. First of all, the operation is relatively complicated, and special tools are needed to install and remove screws, which not only increases the operation time, but also requires a certain skill level of the operator. For example, in some small electric vehicle repair shops, due to incomplete tools or insufficient experience of the operator, the parallel operation time is long, which affects the maintenance efficiency. Secondly, the screw is easy to loosen and lose during use. If the screw is loose, it will cause the enameled wire connection to be not firm, affecting the performance of the motor; if the screw is lost, it also needs to spend time to find the appropriate screw to replace. In addition, during disassembly, tools are needed to tighten the screw, which is easy to damage the enameled wire or other parts. For example, the insulating layer of enameled wire may be scratched during disassembly, causing short circuit and other safety hazards. Moreover, the screw fastening method is more difficult to operate for some limited space motor structures, which requires more time and effort to complete the parallel operation, therefore the technical field proposes a motor wire package parallel structure to solve the above problems.
