[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] During specific implementation: As Figures 1-5 shown, the motor stator-rotor chip insulating device includes: a stator 1; an insulating mechanism 2, and the insulating mechanism 2 is arranged on the surface of the stator 1; wherein, the insulating mechanism 2 includes insulating frames 21 arranged at the top and bottom of the stator 1, the end of the insulating frame 21 is fixedly connected with an insulating soft sleeve 22, an annularly distributed insulating frame 23 is fixedly connected to the inner side of the insulating soft sleeve 22, the surface of the insulating soft sleeve 22 is clamped to the inner side of the stator 1, an insulating soft pad 24 is fixedly connected to the surface of the insulating frame 21, and both the insulating soft sleeve 22 and the insulating soft pad 24 are synthetic rubber components. Synthetic rubber components such as nitrile rubber, silicone rubber, ethylene propylene diene monomer rubber, etc., and specific models can be selected according to actual needs.

[0025] The insulating soft sleeve 22 is installed in the stator 1 through an insulating automatic press-fitting machine, and the insulating frame 21 and the insulating frame 23 are installed on the stator 1. Similarly, the matching insulating soft sleeve 22, insulating frame 21 and insulating frame 23 are installed on the rotor. The wire is installed on the insulating soft pad 24, stator 1 and rotor, and then subsequent assembly and processing are carried out. During the high-speed operation of the motor on the compressor, the vibration generated will be transmitted into the insulating frame 21 and the insulating frame 23. At this time, the insulating soft pad 24 and the insulating soft sleeve 22 neutralize the transmitted vibration force, reduce the wear of the insulating frame 21 and the insulating frame 23, and strengthen the electrical isolation degree between the stator 1 and the rotor inside the motor, avoiding arc or current leakage.

[0026] As Figure 3 shown, the top end of the insulating frame 21 is provided with a first through hole 25 distributed in a ring shape, the top end of the insulating soft sleeve 22 is provided with a second through hole 26 distributed in a ring shape, the first through hole 25 is communicated with the second through hole 26, the inner wall of the insulating soft sleeve 22 is provided with a third through hole 27 distributed in a ring shape, and the second through hole 26 is communicated with the third through hole 27. The inner wall of the first through hole 25 is fixedly connected with an installation frame 29, and a waterproof and breathable film is fixedly connected to the inner side of the installation frame 29. When the motor generates heat during operation, the first through hole 25, the second through hole 26 and the third through hole 27 enable the heat on the insulating frame 21, the insulating soft sleeve 22 and the insulating soft pad 24 to dissipate quickly, avoiding the heat from always accumulating on the insulating frame 21, the insulating soft sleeve 22 and the insulating soft pad 24. The waterproof and breathable film blocks the moisture from entering the insulating soft pad 24, the stator 1 and the insulating frame 23.

[0027] As Figure 3 and Figure 5 shown, the bottom end of the insulating soft sleeve 22 is fixedly connected with an installation rod 210 distributed in a ring shape. Installation grooves 212 are provided at both the top end and the bottom end of the stator 1. The surface of the installation rod 210 is clamped to the inner wall of the installation groove 212. An expansion block 28 is fixedly connected to the inner bottom wall of the installation groove 212. The installation rod 210 is a polystyrene component. A limiting block 211 is fixedly connected to the surface of the installation rod 210, and the surface of the limiting block 211 is clamped to the inner wall of the installation groove 212. The insulating soft sleeve 22 is inserted into the stator 1, so that the installation rod 210 is clamped in the installation groove 212. During the downward movement of the installation rod 210 in the installation groove 212, the expansion block 28 will be inserted into the inner side of the installation rod 210. Because the installation rod 210 is a polystyrene component, it has good elasticity, enabling the limiting block 211 to be stably clamped in the installation groove 212 and enabling the insulating soft sleeve 22 to be stably installed in the stator 1.

[0028] When the utility model is in use, an insulating soft sleeve 22 is installed on a stator 1 through an insulating automatic press-fitting machine, so that a mounting rod 210 is clamped in a mounting groove 212. During the downward movement of the mounting rod 210 in the mounting groove 212, an expansion block 28 will be inserted into the inner side of the mounting rod 210. Since the mounting rod 210 is a polystyrene component, it has good elasticity, enabling a limiting block 211 to be stably clamped in the mounting groove 212, and enabling an insulating frame 21 and an insulating frame 23 to be stably installed on the stator 1. Similarly, a matching insulating soft sleeve 22, insulating frame 21 and insulating frame 23 are installed on a rotor, wires are installed on an insulating soft pad 24, stator 1 and rotor, and then subsequent assembly and processing are carried out. During the high-speed operation of the motor on the compressor, vibrations generated will be transmitted into the insulating frame 21 and insulating frame 23. At this time, the insulating soft pad 24 and insulating soft sleeve 22 neutralize the transmitted vibration force, reducing the wear of the insulating frame 21 and insulating frame 23, and enabling the insulating frame 21 and insulating frame 23 to enhance the electrical isolation degree between the stator 1 and rotor inside the motor, avoiding arc or current leakage.

[0029] It should be noted that in the above description, the stator 1, insulating frame 21, insulating frame 23, etc. are all devices with relatively mature applications in the prior art. Specific models can be selected according to actual needs and will not be elaborated here.

[0030] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
