Detailed Implementation

[0029] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0030] like Figures 1 to 4As shown, a modular brushless motor 10 for car models includes a stator assembly 100, a rear end cover 200, a front end cover 300, a rotor component 400, and several studs 500. The stator assembly 100 includes a housing 110, a stator winding 120, insulating paper 130, a PCB board 140, and several gold-plated posts 150. The stator winding 120 is disposed within the housing 110. The insulating paper 130 is disposed at one end of the stator winding 120. The PCB board 140 is disposed on the side of the insulating paper 130 away from the stator winding 120, and the PCB board 140 is electrically connected to the stator winding 120. A boss 160 is provided on the housing 110. The boss 160 extends radially along the housing 110 to the outside of the housing 110. Each gold plug 150 is spaced apart on the boss 160. The rear end cover 200 is located on the end of the housing 110 near the PCB board 140. The front end cover 300 is located on the end of the housing 110 away from the PCB board 140. The rotor 400 passes through the stator winding 120, and both ends of the rotor 400 are rotatably connected to the front end cover 300 and the rear end cover 200, respectively. Each stud 500 passes through the front end cover 300 and the stator winding 120 to be screwed to the rear end cover 200.

[0031] It should be noted that the stator assembly 100, rear end cover 200, front end cover 300, and rotor 400 are independent modular components. The rotor 400 passes through the stator assembly 100, the rear end cover 200 is installed at the rear end of the stator assembly 100, and the front end cover 300 is installed at the front end of the stator assembly 100, so that both ends of the rotor 400 are rotatably connected to the rear end cover 200 and the front end cover 300, respectively. For example, ball bearings are installed on both the front end cover 300 and the rear end cover 200, and both ends of the rotor 400 pass through the ball bearings of the front end cover 300 and the rear end cover 200. After all the studs pass through the front end cover 300 and the stator assembly 100, they are then screwed to the rear end cover 200 to form the modular brushless motor 10 for car models of this application. Furthermore, the stator assembly 100 is also a modular design, which facilitates production and assembly. Specifically, the stator winding 120 is installed inside the housing 110, the insulating paper 130 is installed on the end of the stator winding 120, and the PCB board 140 is installed on the insulating paper 130. The PCB board 140 is electrically connected to the coil of the stator winding 120. Further, the PCB board 140 extends radially to form a boss 160, which extends to the outside of the housing 110. Each gold pin 150 is spaced apart and installed on the boss 160. It should be noted that each gold pin 150 is electrically connected to the coil of the stator winding 120. In this way, the housing 110, stator winding 120, insulating paper 130, PCB board 140, and several gold pins 150 are modular components, which facilitate the assembly and fixing of the rear end cover 200 and the front end cover 300 into a modular brushless motor 10 for car models using screws 500. With its compact structure and modular design of each component, it facilitates production and assembly, thereby improving assembly efficiency and reducing production costs.

[0032] like Figure 4 As shown, in one embodiment, the stator winding 120 includes a stator base 121, two insulating covers 122 and three stator coils 123. The two insulating covers 122 are respectively disposed at both ends of the stator base 121. The three stator coils 123 are spaced apart inside the stator base 121. One end of the three stator coils 123 is connected to each other, and the other end of each of the three stator coils 123 is electrically connected to the PCB board 140.

[0033] It should be noted that the stator base 121 is a steel structure, and two insulating covers 122 abut against both ends of the stator base 121. Three stator coils 123 are wound spaced apart inside the stator base 121, with one end of each coil connected together. The other ends of the coils are soldered to the PCB board 140, which in turn connects to three metal terminals 150. Thus, the modular brushless motor 10 formed by assembly can be electrically connected to the three stator coils 123 via the three metal terminals 150.

[0034] In one embodiment, two insulating papers 130 are provided, and the two insulating papers 130 are respectively provided on the ends of the two insulating covers 122 that are away from the stator base 121.

[0035] Thus, the PCB board 140 and the stator coil 123 are separated by insulating paper 130, which prevents the PCB board 140 and the stator coil 123 from short-circuiting and improves the reliability of the assembled stator assembly 100.

[0036] like Figure 3 and Figure 4 As shown, in one embodiment, the stator base 121, the insulating cover 122, the insulating paper 130, and the PCB board 140 are all provided with a plurality of clearance slots 101, and each stud 500 is respectively inserted into each clearance slot 101.

[0037] This allows the stud 500 to pass through the clearance groove 101, so that the front cover 300 and the rear cover 200 can be reliably fixed to both ends of the housing 110.

[0038] In one embodiment, the outer wall of the stator base 121 is bonded to the inner wall of the housing 110.

[0039] Specifically, the outer wall of the stator base 121 is bonded and fixed to the inner wall of the housing 110 with glue, thereby improving the overall structural strength of the stator assembly 100.

[0040] In one embodiment, the boss 160 has a plurality of through holes, and each gold insert 150 is inserted into each through hole.

[0041] Thus, by pre-drilling through holes on the boss 160, the gold insert 150 can be quickly inserted and fixed onto the boss 160, simplifying the assembly difficulty between the gold insert 150 and the PCB board 140.

[0042] In one embodiment, the gold pin 150 is soldered to the PCB board 140. This ensures that the gold pin 150 and the PCB board 140 are reliably fixed together, preventing them from becoming loose. Moreover, the modular car model brushless motor 10 has a compact and simple structure, with little space occupied by the wiring, making it convenient for users to connect and use.

[0043] like Figure 4 As shown, in one embodiment, a current-carrying copper strip 170 is also provided on the PCB board 140. In this way, by soldering the current-carrying copper strip 170, the current-carrying capacity of the PCB board 140 can be enhanced.

[0044] like Figures 1 to 3 As shown, in one embodiment, the housing 110 has a groove 111, and the boss 160 is adapted to be accommodated in the groove 111.

[0045] Thus, the boss 160 is adapted to be housed in the groove 111, which is equivalent to achieving rapid and accurate positioning when the stator winding 120 is quickly assembled with the housing 110, effectively preventing misalignment between the stator winding 120 and the rotor component 400, and improving the installation accuracy and stability of the modular car model brushless motor 10.

[0046] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
