[0002] Brushless Motor is a type of motor, also known as brushless DC motor or electronic speed control motor. Compared with traditional brushed DC motor, brushless motor does not need brushes and collector rings for commutation, so it has higher efficiency, longer life and lower maintenance requirements. The working principle of brushless motor is to use electronic controller to realize timely switching of current to drive the motor rotor to rotate. It usually consists of stator and rotor. The stator contains several coils, which generate a rotating magnetic field by switching current. Permanent magnets or magnets are installed on the rotor, which rotate under the action of the rotating magnetic field.

[0003] When the brushless motor is in use, a wiring harness needs to be connected to control the motor; the existing motor connection harness is generally directly connected to the motor, and no plug-in connector is provided on the motor. The connection cannot be effectively plugged in and out during use, which is inconvenient to use. Utility Model Content

In this embodiment, a connecting mounting groove 14 is arranged on the base 1 for the installation of the first connector 2. After the first connector 2 is installed, it is connected to the control board inside the motor, and then the second connector 3 with the wiring harness is connected to the first connector 2 through plugging. The wiring harness does not need to be directly connected to the control board of the motor, and the connection is more convenient. In addition, the two sets of connectors are plugged in, and the connection is stable and the transmission performance is good. The problem of unstable connection and inconvenience in use of the existing motor wiring harness is solved.

[0029] In the above-mentioned embodiment, the wiring harness can be easily plugged in and out through the design of the first connector 2 and the second connector 3. This structure makes it easy to replace and repair the wiring harness, saving time and cost. The setting of the fixed mounting platform 12 and the connecting mounting groove 14 enables the first connector 2 to be firmly mounted on the base 1. This ensures that the connection between the wiring harness and the brushless motor is firm and reliable, avoiding loosening and falling off. Since the wiring harness can be quickly plugged in and out, when it needs to be replaced or repaired, there is no need to disassemble the entire brushless motor, and only the wiring harness needs to be simply plugged in and out. This saves time and energy and improves work efficiency.

[0030] In the above embodiment, by installing the first connector 2 in the connection installation groove 14, the wiring harness can be better tightly integrated with the brushless motor without taking up additional space. This is particularly important for application scenarios with space constraints. The cooperation between the first connector 2 and the second connector 3 makes the electrical connection stable and reliable. This design can effectively prevent electrical connection problems such as poor contact and short circuit, and ensure the transmission quality and stability of electrical signals. The wiring harness can be quickly plugged in and out and connected firmly, improving work efficiency and reliability. This brings convenience to operations such as installation, maintenance and replacement of the wiring harness of the brushless motor, and also improves the reliability and service life of the overall system.

[0031] The fixed mounting platform 12 is arranged at one end of the motor mounting platform 11, and one end of the motor mounting platform 11 is arranged inside the motor. Specifically, the fixed mounting platform 12 is provided with a mounting surface 121, and the mounting surface 121 is provided with a mounting hole 122. In this embodiment, the motor mounting platform 11 is used for mounting the stator or rotor of the motor, and is installed inside the motor housing when in use to facilitate the installation of internal components. The mounting surface 121 and the mounting hole 122 are provided for the fixed installation of the base 1 so that it can be used in different scenarios.

[0032] A groove 123 is provided on one side of the fixed installation platform 12 close to the connecting platform 13. The arrangement of the groove 123 facilitates the opening of the connecting installation slot 14 on the connecting platform 13, and also facilitates the plugging of the connector.

[0033] One end of the connection installation groove 14 is connected from the connection platform 13 to the motor installation platform 11. Specifically, a convex strip is provided at the groove wall of the connection installation groove 14, and the convex strip is used to tightly fit the first connector 2 in the connection installation groove 14. In this embodiment, the connection installation groove 14 is set in a through manner to facilitate the assembly of the first connector 2. A convex strip is provided in the connection installation groove 14, and the first connector 2 is tightly fitted and installed through the convex strip to ensure structural stability.

[0034] The first connector 2 includes a first housing 21, a plug port 22 disposed on the first housing 21, and a contact terminal 23 disposed in the first housing 21 and extending to the plug port 22 at one end; the second connector 3 is used to be inserted into the plug port 22; the second connector 3 includes a second housing 31, a connection plug 32 disposed at one end of the second housing 31, and a plug terminal 33 disposed in the second housing 31 and extending to the connection plug 32 at one end; the connection plug 32 is used to be inserted into the plug port 22 to contact the contact terminal 23 with the plug terminal 33. In this embodiment, through the design of the first connector 2 and the second connector 3, a reliable connection between the contact terminal 23 and the plug terminal 33 can be achieved. This connection method ensures the stable transmission of current, reduces the occurrence of problems such as poor contact and contact impedance, and improves the performance and reliability of the motor. The connection plug 32 can be easily inserted into the plug port 22 of the first connector 2 to achieve fast wiring harness plugging and unplugging. This can save time and energy, and facilitate operations such as installation, maintenance and replacement of wiring harnesses of the motor.

[0035] A guiding bevel 221 is provided at the opening of the plug port 22; the insertion end of the plug port 22 faces the connection platform 13. In this embodiment, the guiding bevel 221 of the plug port 22 can guide the connection plug 32 of the second connector 3 to be correctly inserted into the plug port 22. In this way, the plugging process is smoother, the friction and resistance during plugging are reduced, and the accuracy and stability of the connection are improved. The insertion end of the plug port 22 faces the connection platform 13, so that the second connector 3 can be easily inserted into the base 1 of the motor. This design makes the plugging and unplugging process simpler and faster, saving operation time and labor.

[0036] Plug-in slots 222 are provided on both sides of the plug-in port 22, and plug-in buckles 321 are provided on both sides of the connecting plug 32.
