Description

Technical Field

[0001] The utility model belongs to the technical field of motor casings, in particular to a shock absorbing structure of a motor casing. Background Art

[0002] A motor refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. An electric motor converts electric energy into mechanical energy (commonly known as a motor). The electric motor is represented by the letter "M" in the circuit. Its main function is to generate driving torque as a power source for electrical appliances or various machines. According to the purpose, it can be divided into: driving motors and control motors. The motor will generate vibrations during operation. The vibrations will be transmitted to the mounting structure through the casing, thereby causing the mounting structure to vibrate. Long-term vibrations will cause the mounting structure to loosen. Once the structure is loose, the vibrations during the operation of the motor will directly convert into strong noise. For this reason, this application proposes a motor casing shock-absorbing structure. Utility Model Content

Through the cooperation between the card blocks 5 at the bottom of the motor 2 and the card slots 4, the bottom of the motor 2 can be stably located in the storage slot at the top of the base 3.

[0022] In addition, the size of the connecting plate 8 is compatible with the size of the connecting groove 7, and the diameter of the screw 11 is the same as the diameter of the through opening 10 and the through hole 9, so that the screw 11 will not shake when inserted into the through opening 10 and the through hole 9, and the connecting plate 8 can also be stably fixed in the connecting groove 7.

[0023] In addition, the curvature of the bending part of the through hole 9 is the same as the curvature of the bending part of the screw rod 11 , so that the outer wall of the screw rod 11 can fit tightly with the inner wall of the through hole 9 .
