[0022] See also Figure 1-5 The utility model provides an embodiment: an automobile air-conditioning clutch, comprising a pulley body 1 and a suction cup body 2, the front end of the pulley body 1 is provided with the suction cup body 2, the front end of the suction cup body 2 is fixedly connected with a turntable 3, the turntable 3 is annularly equidistantly provided with limit blocks 4, the left and right ends of the limit blocks 4 are provided with movable plates 5, the rear end of the pulley body 1 is provided with an electromagnetic coil body 7, the electromagnetic coil body 7 is provided with a heat dissipation component, the limit block 4 is provided with a movable component, and the rear end of the pulley body 1 is provided with an engine body 10, such as Figure 1 As shown, the device solves the problem that most of the related devices mentioned above need to be connected to the air-conditioning compressor at one end when in use, and the connection structure of the device is simple and the fit is limited, so that it will slip sideways when in use, and will also affect the working process. In addition, the device will generate a lot of heat when it is used for power generation, and the heat needs to be quickly dissipated. In addition, the structure of the device is relatively simple, and it is quick and convenient to use. In addition, the device has good practicality, and the production cost is relatively low, which is convenient for promotion and use.

[0023] Furthermore, the heat dissipation assembly includes an air duct 6, a motor body 8 and a fan blade body 9. The pulley body 1 is provided with an air duct 6 at equal intervals in an annular manner. The motor body 8 is provided in the electromagnetic coil body 7. The output end of the motor body 8 is fixedly connected to the fan blade body 9. Figure 1 and Figure 2 As shown, this structure makes it easy for the motor body 8 to start and drive the fan blade body 9 at its output end to rotate when the electromagnetic coil body 7 generates a large amount of heat, so that the heat generated by the electromagnetic coil body 7 can be quickly dissipated through the air duct 6, and the structure is simple and convenient to use.

[0024] Further, the movable assembly includes a movable groove 11, a spring body 12, a movable block 13 and an anti-sliding block 14. The movable groove 11 is opened in the limit block 4, and the spring body 12 is equidistantly arranged in the movable groove 11. The movable block 13 is arranged at one end of the spring body 12 close to the movable plate 5, and the outer wall of the movable plate 5 is equidistantly arranged with anti-sliding blocks 14. Figure 4 and Figure 5 As shown, this structure facilitates the connection between the limit block 4, the movable plate 5 and the air-conditioning compressor to be more precise, so that it will not slip sideways during use, and the device can be fixed more quickly. The device has a simple structure and good practicality.

[0025] Furthermore, the inner wall of the air passage 6 is made of copper, the suction cup body 2 and the turntable 3 are disc-shaped, and the limit blocks 4 are three groups equidistantly arranged in a circle of the turntable 3, such as Figure 1 As shown, the structure has better thermal conductivity and a smoother round shape, making it easier to rotate and use the device.

[0026] Further, the movable block 13 is a T-shaped block, the movable groove 11 is a T-shaped groove, the movable groove 11 and the movable block 13 are adapted, and the track of the movable groove 11 is an arc, such as Figure 4 and Figure 5 As shown, this structure facilitates the stable sliding of the movable block 13 in the movable groove 11 so that the movable block 13 will not accidentally slide off during the sliding period.

[0027] Furthermore, the outer wall edge of the movable plate 5 is arc-shaped, and the movable plate 5 is made of rubber material. The hardness of the movable plate 5 is greater than the hardness of the anti-sliding block 14. Figure 5 As shown, the arc shape has no obvious edges and corners, which effectively prevents the movable plate 5 from scratching the outer wall of the device or the skin of the staff during use, and makes the connection fit of the device higher and the stability better.

[0028] Furthermore, the anti-sliding block 14 is made of rubber material, the outer wall of the anti-sliding block 14 is rough, and the anti-sliding block 14 is hemispherical. Figure 5 As shown, this structure facilitates the anti-sliding block 14 in the device to produce a certain deformation when pressure is generated, so that the anti-sliding block 14 and the movable plate 5 are more tightly connected with the relevant clamping components, and the structure is simple and quick and convenient to use.

[0029] Working principle: When in use, first place the device on a horizontal working surface, and then connect and fix the pulley body 1 and the electromagnetic coil body 7 and other related components. Then, when the electromagnetic coil body 7 generates a large amount of heat during operation, start the motor body 8 at the front end of the engine body 10. The motor body 8 drives the fan blade body 9 at its output end to rotate, so that the fan blade body 9 drives the air flow in the hole groove of the electromagnetic coil body 7, and dissipates the heat from the air duct 6 to the outside through the air flow. At the same time, the heat is dissipated from the air duct 6 through heat conduction. When it is necessary to connect and fix the turntable 3 on the suction cup body 2 with the related components, first push the limit block 4 toward one end of the air-conditioning compressor. During this period, the movable block 13 slides in the movable groove 11 and compresses the spring body 12. The movable plate 5 is arranged in the groove along the shape of the air-conditioning compressor, and the anti-sliding block 14 is compressed to produce corresponding deformation. During this period, the spring body 12 produces a strong restoring elastic force, which can make the movable plate 5 and the anti-sliding block 14 tightly fit with one side of the air-conditioning compressor. The device is not only simple in structure, but also convenient and quick to use. The above is the entire working principle of the utility model.

[0030] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
