Description

Technical Field

[0001] This utility model relates to the field of motor hook frame technology, specifically a motor hook frame with high safety. Background Technology

[0002] Although brushless motors have a relatively short history of development in my country, they have experienced rapid growth due to the increasing maturity and sophistication of the technology. They are now widely used in various fields such as model aircraft, medical devices, home appliances, and electric vehicles. A brushless motor consists of a motor body and a driver, making it a typical mechatronic product. Structurally, brushless motors are similar to brushed motors, also having a rotor and stator, but their structures are reversed. In a brushed motor, the rotor is a coil winding connected to the power output shaft, and the stator is a permanent magnet. In a brushless motor, the rotor, along with the housing, is a permanent magnet connected to the output shaft, and the stator is a coil winding. It eliminates the commutator brushes used in brushed motors to alternately change the electromagnetic field, hence the name "brushless motor." Brushless motors use semiconductor switching devices to achieve electronic steering, replacing the contact commutator and brushes of traditional brushed motors. Therefore, the wiring connection between the electronic switching devices and the brushless motor stator must be secure and reliable.

[0003] In response, Chinese utility model patent CN214384883U discloses a wear-resistant motor hook bracket with a long service life, including a connecting part.

One end of the fixing cap is rotatably connected to the connecting part through a threaded structure. Several hook brackets are coaxially slidably engaged with the outer wall of the connecting part. The structure of sliding engagement between the fastening parts and the hook brackets facilitates the assembly and disassembly of the hook brackets. With the fixing cap, it can be securely installed on the motor shaft, and the structure is sturdy and safe. The two connecting pieces of the hook bracket facilitate the fixing of the wiring and are compatible with different types of motors.

[0004] The hook structure in this device has the potential to detach during operation. To address this issue, we propose a highly safe motor hook frame. Utility Model Content
