Description

Technical Field

[0001] This utility model belongs to the field of motors, and in particular relates to a brushed motor that can be equipped with dual switches. Background Technology

[0002] Brushed motors are now widely used in many household appliances. During assembly, to prevent the coils from becoming tangled, they are wound around the stator frame and bound with cable ties, requiring considerable manpower. Furthermore, to facilitate connection to external switches, a wire is pulled out from one end of the coil and connected to an external plug. This external plug then engages with the corresponding switch to achieve electrical conductivity. Therefore, the overall wiring is complex, and switch assembly is inconvenient. Utility Model Content

[0003] The purpose of this invention is to provide a brushed motor that can be equipped with a dual switch, which can solve at least one of the above problems.

[0004] According to one aspect of the present invention, a brushed motor capable of mounting dual switches is provided, comprising a front bracket, a rear bracket, a stator assembly, a rotor assembly, a shaft, a carbon brush assembly, and a fan blade. The stator assembly includes a stator frame and a coil. The front bracket and the rear bracket are respectively fixed on the upper and lower sides of the stator frame. The coil is wound on the stator frame. The rotor assembly is disposed on the shaft and located inside the stator assembly. The two ends of the shaft pass through the front bracket and the rear bracket respectively. The fan blade is fixed to one end of the shaft. A commutator is provided on the shaft. The carbon brush assembly is disposed on the rear bracket and is correspondingly arranged with the commutator. The carbon brush assembly is electrically connected to the coil. The rear bracket is provided with a slot.

[0005] The beneficial effects of this utility model are: by providing a slot on the rear bracket, a micro switch can be easily installed in the slot, and the corresponding end of the coil can be connected to the micro switch in the slot. There is no need for external wires to connect to the switch or other structures, which greatly simplifies the wiring structure, reduces wiring, and facilitates connection with external structures.

[0006] In some implementations, there are two slots. This facilitates the installation of two microswitches to meet the corresponding usage requirements.

[0007] In some embodiments, a brushed motor capable of mounting dual switches further includes an upper winding frame and a lower winding frame. The upper winding frame is fixed to the upper end of the stator winding frame, and the lower winding frame is fixed to the lower end of the stator winding frame. The upper and lower winding frames are correspondingly arranged, and the coils are wound on the upper and lower winding frames. The number of upper and lower winding frames is consistent with the number of coils. Thus, the upper and lower winding frames can limit and fix the coils, preventing them from becoming tangled, eliminating the need for manual binding straps, facilitating automated operation, and saving labor.

[0008] In some embodiments, the lower wire frame is provided with two sockets, each containing a terminal. Each terminal is connected to a coil, and the carbon brush assembly is electrically connected to the corresponding terminal. Slots are correspondingly provided with the corresponding terminals. Thus, the sockets facilitate the installation of terminals; the terminals facilitate the connection to the carbon brush assembly and the coil, reducing the need for external wires and shortening the length of the coil pulled out at both ends.

[0009] In some implementations, the rear bracket has mounting holes into which the carbon brush assembly is inserted. This mounting hole facilitates the installation of the carbon brush assembly.

[0010] In some embodiments, the carbon brush assembly includes a carbon brush holder that mates with a mounting hole. A spring is provided at the end of the carbon brush holder, which abuts against a terminal. Thus, the contact between the spring and the terminal facilitates connection without the need for additional wiring.

[0011] In some embodiments, the rear bracket is provided with a mounting slot located on one side of the slot. This mounting slot facilitates the installation of other external structures.

[0012] In some embodiments, the rear bracket is provided with two mounting posts, each with a fixing hole, and the mounting posts are fixed to the stator frame. Thus, by providing mounting posts, the installation and fixing of the rear bracket on the stator frame is facilitated.

[0013] In some implementations, both the upper and lower conductor frames are equipped with pins, and the stator conductor frame has corresponding sockets, with the pins and sockets engaging with each other. Thus, the upper and lower conductor frames can be quickly installed on the stator conductor frame through the engagement of the pins and sockets. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] Reference Figures 1-6 A brushed motor capable of mounting dual switches includes a front bracket 1, a rear bracket 2, a stator assembly 3, a rotor assembly 4, a shaft 5, a carbon brush assembly 6, and a fan blade 7. The stator assembly 3 includes a stator wire frame 31 and a coil 32. The front bracket 1 and the rear bracket 2 are respectively fixed to the upper and lower sides of the stator wire frame 31. The coil 32 is wound on the stator wire frame 31. The rotor assembly 4 is mounted on the shaft 5 and located inside the stator assembly 3. The two ends of the shaft 5 pass through the front bracket 1 and the rear bracket 2, respectively. The fan blade 7 is fixed to one end of the shaft 5. A commutator 8 is provided on the shaft 5. The carbon brush assembly 6 is mounted on the rear bracket 2 and is correspondingly arranged with the commutator 8. The carbon brush assembly 6 is electrically connected to the coil 32. The rear bracket 2 has two slots 21.

[0022] In actual use, microswitches are inserted into the two slots 21, and the corresponding ends of coil 32 are pulled to the slots 21 to achieve connection with the microswitches, which is convenient.

[0023] The present invention provides a brushed motor capable of mounting dual switches, which further includes an upper winding frame 9 and a lower winding frame 10. The upper winding frame 9 is fixed to the upper end of the stator winding frame 31, and the lower winding frame 10 is fixed to the lower end of the stator winding frame 31. The upper winding frame 9 and the lower winding frame 10 are arranged correspondingly, and the coil 32 is wound on the upper winding frame 9 and the lower winding frame 10. The number of the upper winding frame 9 and the lower winding frame 10 is the same as the number of the coil 32.

[0024] Specifically, the upper wire frame 9 and the lower wire frame 10 are each formed with a pin 30. The upper and lower end faces of the stator wire frame 31 are respectively provided with insertion holes 311 (not shown in the figure, but obscured by the upper and lower wire frames). The pins 30 mate with the corresponding insertion holes 311. During assembly, the pins 30 of the upper wire frame 9 are inserted into the corresponding insertion holes 311 to fix the upper wire frame 9 to the stator wire frame 31; similarly, the lower wire frame 10 is also fixed to the stator wire frame 31. After the upper wire frame 9 and the lower wire frame 10 are fixed to the stator wire frame 31, the coils are wound on the wire frames. There are two coils 32, and both the upper wire frame 9 and the lower wire frame 10 have two coils. The top of the upper wire frame 9 is higher than the top of the coil 32, and the bottom of the lower wire frame 10 is higher than the bottom of the coil 32.

[0025] By providing an upper wire frame 9 and a lower wire frame 10, the coil 32 can be limited to prevent it from contacting the rotor and ensure the normal operation of the motor. The limiting effect of the upper wire frame 9 and the lower wire frame 10 can also prevent the coil from becoming messy, eliminating the need for manual binding straps.

[0026] The lower wire frame 10 has two sockets 101 formed on it. Each socket 101 has a terminal 20 inserted into it. The terminal 20 is fixed on the socket 101 and each terminal 20 is connected to the coil 32. The carbon brush assembly 6 is electrically connected to the corresponding terminal 20. The slot 21 is set to correspond to the corresponding terminal 20. That is, the micro switch inserted in the slot 21 makes contact with the corresponding terminal 20 and conducts electricity. It is easy to install.

[0027] The rear bracket 2 has mounting holes, into which the carbon brush assembly 6 is inserted.

[0028] The carbon brush assembly 6 includes a carbon brush box 61, which mates with a mounting hole. A spring 62 is provided at the tail end of the carbon brush box 61, which abuts against the terminal 20.

[0029] The rear bracket 2 is provided with a mounting groove 22, which is located on one side of the slot 21.

[0030] The rear bracket 2 is provided with two mounting posts 23, and the mounting posts 23 are provided with fixing holes 231. The mounting posts 23 are fixed to the stator wire frame 31. The mounting posts 23 and the rear bracket 2 are integrally injection molded structures. After the rear bracket 2 is positioned on the stator wire frame 31, external screws are locked and fixed to the stator wire frame 31 through the fixing holes, thereby fixing the rear bracket 2.

[0031] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
