Electric scroll compressors are an important part of new energy vehicles. As the core component of the air-conditioning system of new energy vehicles, the role played by electric compressors is irreplaceable.

[0003] Electric compressors have extremely high product requirements. Some motor stators need to be baked at high temperatures during the manufacturing process to solidify the insulating paint and improve the insulation level of the motor. However, the frame of the motor stator is prone to deformation and inward expansion in a high temperature environment, which can cause interference during stator and rotor assembly, resulting in a series of problems such as low product qualification rate and low shipment volume.

[0004] The utility model improves the above-mentioned problem and specifically relates to an auxiliary support mechanism for a motor stator frame. Utility Model Content

When the built-in stud moves upward, it will pass through the top surface cone to top the slope moving column, and the slope moving column will move outward.

[0011] Preferably, vertical lines are arranged on the outer side of the toggle adjustment knob, and connecting threads are arranged on the inner side of the toggle adjustment knob.

The caliper body includes an arc-shaped outer wall, a top core groove surface and a screw insertion hole. The caliper body is connected through the arranged screw body through the caliper sliding rail and the screw insertion hole. When the top core moves, the top core groove surface is squeezed by its slope surface to make the caliper body move sideways, so as to adapt to motor stator frames with different inner diameters. When the arc-shaped outer wall of the caliper touches the motor stator frame, the threaded top is stopped from rotating, so that the inner supporter can be stably placed on the motor stator. The utility model can stably support the motor stator frame, effectively avoid deformation and inward expansion in a high temperature environment, so that interference occurs during stator and rotor assembly, resulting in a series of problems such as low product qualification rate and small shipment volume, thereby effectively improving its practicality.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides Figure 1-4As shown, an auxiliary support mechanism for a motor stator skeleton comprises a top core 7 and a connecting cover plate 4 arranged at the side position of the top core 7; a caliper sliding track 5 is arranged at the middle position of the connecting cover plate 4, and a caliper body 1 is connected to the connecting cover plate 4, the caliper body 1 comprises an arcuate outer wall 11, a top core groove surface 10 and a screw insertion hole 12, the caliper body 1 is connected through the arranged screw body 6 through the caliper sliding track 5 and the screw insertion hole 12, when the top core 7 moves, the top core groove surface 10 is squeezed by its slope surface so that the caliper body 1 can move sideways to adapt to motor stator skeletons with different inner diameters, when the arcuate outer wall 11 of the caliper touches the motor stator skeleton, the thread top is stopped from rotating, so that the inner supporter can be stably placed on the motor stator, and the motor stator skeleton can be stably supported by the utility model, which can effectively avoid deformation and inward expansion in a high temperature environment, so that interference occurs during the assembly of the stator and rotor, resulting in a series of problems such as low product qualification rate and small shipment volume, thereby effectively improving its practicality.

[0024] like Figure 1 As shown, a connecting threaded cylinder 2 is connected to the end position of the top core 7, the outer diameter of the connecting threaded cylinder 2 is equal to the central inner diameter of the connecting cover plate 4, and the middle position of the connecting cover plate 4 is a threaded through hole. The threaded connection structure allows the user to rotate the connecting threaded cylinder 2 to make the connecting threaded cylinder 2 move relatively along the connecting cover plate 4.

[0025] like Figure 1 As shown, a top rotating handle 3 is provided at the end position of the connecting threaded column 2, and the top rotating handle 3 is a square-shaped structure. The top rotating handle 3 and the connecting threaded column 2 are an integrated structure. The top rotating handle 3 with a square-shaped structure is more convenient for the user to hold, so that the rotation operation can be better performed. The connecting threaded column 2 is matched with the connecting cover plate 4, and the required size can be better selected.

[0026] like Figure 4 As shown, a toggle adjustment knob 9 is provided at the middle position of the connecting threaded cylinder 2, and a built-in stud 13 is provided on the inner wall of the toggle adjustment knob 9, and a top cone body 14 is provided at the upper end position of the built-in stud 13, and a slope moving column 17 is provided at the upper side position of the top cone body 14, and the outer side surface of the slope moving column 17 is a side groove 8. Rotating the toggle adjustment knob 9 can make the built-in stud 13 move up and down. When the built-in stud 13 moves up, it will pass through the top cone body 14 to the top of the slope moving column 17, and the slope moving column 17 will move outward. The lateral movement of the slope moving column 17 can increase the moving distance of the caliper, thereby increasing the adjustment range of the auxiliary support mechanism of the motor stator skeleton, thereby further improving its practicality.

[0027] like Figure 4As shown, vertical lines are arranged on the outer side of the toggle adjustment knob 9, and a connecting thread is arranged on the inner side of the toggle adjustment knob 9. The vertical lines on the outer side of the toggle adjustment knob 9 can increase the friction between the user's hand and the toggle adjustment knob 9, thereby avoiding the phenomenon that the user and the toggle adjustment knob 9 are unable to rotate due to relative sliding.

[0028] like Figure 4 As shown, a limiting slot column 15 is arranged at the upper end position of the slope moving column 17, and the length of the limiting slot column 15 is the same as the movable distance of the slope moving column 17. An extrusion return spring 16 is arranged in the limiting slot column 15, and the limiting slot column 15 is elastically connected to the top core 7 through the extrusion return spring 16. The limiting slot column 15 can effectively prevent the slope moving column 17 from being separated from the top core 7 and lost, and the extrusion return spring 16 can make the slope moving column 17 automatically return to its original position when the top surface frustum 14 descends.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
