[0026] See also Figure 1-3 , an automobile air-conditioning electromagnetic clutch coil frame, comprising a frame body and a fixing mechanism, wherein the fixing mechanism is arranged on the frame body.

[0027] Example 1

[0028] The skeleton body includes a clutch magnetic wheel 1, a fixed key wheel 2 is fixedly installed in the middle of the top of the clutch magnetic wheel 1, a circle of winding cavity groove 3 is arranged on the outer wall of the fixed key wheel 2 on the top of the clutch magnetic wheel 1, a circle of electric drive sleeve 4 is arranged on the top of the winding cavity groove 3, a layer of electric drive plate 5 is arranged on the top of the electric drive sleeve 4, and a key groove 6 is opened in the middle of the top of the electric drive plate 5.

[0029] In this embodiment, a buckle ring groove 9 is provided between the bottom of the clutch magnetic wheel 1 and the outer wall of the fixed key wheel 2 , and a plurality of fixing holes are provided on the surface of the clutch magnetic wheel 1 .

[0030] It should be noted that the buckle ring groove 9 can fix the entire clutch coil on the clutch, and the fixing hole can additionally limit and fix the clutch magnetic wheel 1.

[0031] In this embodiment, a coil 10 is wound on the inner surface of the winding cavity 3 , and a wire outlet 11 is opened on the outer wall of the winding cavity 3 .

[0032] It should be noted that the function of the coil 10 is to generate an electromagnetic field to realize the operation of the clutch. The function of the wire outlet 11 opened on the outer wall of the winding cavity 3 is to facilitate the lead wire of the coil 10 to be led out and connected to an external power supply or control circuit. This design can make the connection between the coil 10 and the external circuit more convenient, and is also beneficial to the installation and maintenance of the coil 10.

[0033] In this embodiment, a circle of brake pads 12 is arranged between the electric drive sleeve 4 and the electric drive plate 5 above the coil 10 , and the brake pads 12 are sleeved on the protrusions on the top of the electric drive sleeve 4 .

[0034] It should be noted that the function of the brake pad 12 is to increase the friction and connection force between the electric drive sleeve 4 and the electric drive plate 5. When the electromagnetic clutch is working, the current passes through the coil 10 to generate a magnetic field, causing the electric drive sleeve 4 to be affected by the electromagnetic force, thereby generating relative movement with the electric drive plate 5. The brake pad 12 is sleeved on the protrusion on the top of the electric drive sleeve 4. When the electric drive sleeve 4 moves, the friction between the brake pad 12 and the electric drive plate 5 will hinder the sliding of the electric drive sleeve 4, thereby maintaining the relative position between the electric drive sleeve 4 and the electric drive plate 5 stable. In this way, the components can prevent the electric drive sleeve 4 and the electric drive plate 5 from loosening or falling off during operation, thereby improving the stability and reliability of the electromagnetic clutch, while also reducing the wear between the electric drive sleeve 4 and the electric drive plate 5 and extending their service life.

[0035] In this embodiment, a spring sheet 13 is fixedly mounted on the top of the electric drive board 5 , and the spring sheet 13 is provided with a plurality of positioning holes.

[0036] It should be noted that the spring piece 13 can connect the electric drive board 5 to the shaft for rotation, and can return the electric drive board 5 to its original position when the power is cut off.

[0037] Example 2

[0038] The fixing mechanism includes a positioning groove 7 provided at the connection between the outer wall of the winding cavity groove 3 and the inner wall of the electric drive sleeve 4, a plug connector 8 is inserted into the positioning groove 7, and the end of the plug connector 8 away from the positioning groove 7 is arranged on the inner wall of the electric drive sleeve 4 and penetrates the outer wall of the electric drive sleeve 4.

[0039] In this embodiment, a push rod 14 is fixedly installed at the bottom of the plug connector 8 , and the bottom of the push rod 14 passes through the bottom of the electric drive sleeve 4 .

[0040] It should be noted that, by pressing the ejector rod 14 , the plug connector 8 can be released from the fixing of the positioning groove 7 , so that the electric drive sleeve 4 can be quickly taken out to replace the coil 10 wound inside the cavity groove 3 .

[0041] To sum up, the automobile air-conditioning electromagnetic clutch coil skeleton is provided with a positioning groove 7 at the connection between the winding cavity 3 and the electric drive sleeve 4, and is connected through the plug connector 8, so that the coil 10 inside the winding cavity 3 can be sealed and fixed relatively quickly. At the same time, a push rod 14 is arranged at the bottom of the plug connector 8. By pressing the push rod 14, the plug connector 8 is pushed out of the positioning groove 7 to quickly release the fixation, so as to replace the coil 10 inside the winding cavity 3, which greatly shortens the disassembly and assembly time and is convenient for users.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
