[0027] See also Figure 1-3The utility model provides a coil protection component, which is applied to a motor stator, including a protective cover 31 and a fixing component 32 arranged on the motor stator. The protective cover 31 and the fixing component 32 wrap the end of the coil 2 of the motor stator. The fixing component 32 includes a hanging plate 321 arranged on the motor stator. The protective cover 31 is provided with a hook 311, and the hanging plate 321 is connected to the hook 311. The utility model wraps the exposed end of the coil 2 inside through the protective cover 31 and the fixing component 32, which can prevent the coil 2 from colliding with other components during installation or operation, and can effectively protect the coil 2 to prevent the coil 2 from being damaged, thereby increasing the service life of the motor stator and improving product reliability and safety.

[0028] As an embodiment of the utility model, the coil 2 passes through the hanging plate 321, the fixing component 32 also includes an inner baffle 322 arranged on the hanging plate 321, and the protective cover 31 includes a top plate 312, a front baffle 313, a rear baffle 314 and an outer baffle 315. The top plate 312 is arranged opposite to the hanging plate 321, the front baffle 313 is arranged opposite to the rear baffle 314, and the inner baffle 322 is arranged opposite to the outer baffle 315. A six-sided geometric structure is formed by the top plate 312, the hanging plate 321, the front baffle 313, the rear baffle 314, the outer baffle 315 and the inner baffle 322, and the end of the coil 2 is wrapped inside the geometric structure, so that the end of the coil 2 is protected in all directions and the protection quality is improved.

[0029] Preferably, the geometric mechanism can adopt a variety of shapes according to the specific motor stator structure, such as a cube, a cuboid, a trapezoidal platform or other geometric shapes, and can even adopt an irregular geometric shape, as long as the protection function of the coil 2 is met. The preferred structure provided by the utility model is as follows:

[0030] Protective cover 31: the top plate 312 is parallel to the mounting plate 321, the front baffle 313 and the rear baffle 314 are both inclined, the end of the front baffle 313 close to the mounting plate 321 is outwardly spread, the end of the rear baffle 314 close to the mounting plate 321 is outwardly spread, the outer baffle 315 connects the top plate 312, the front baffle 313 and the rear baffle 314, and the outer baffle 315 is perpendicular to the top plate 312;

[0031] The fixing component 32: the hanging plate 321 is perpendicular to the inner baffle plate 322. The inner baffle plate 322 is an arc-shaped plate. The side of the inner baffle plate 322 close to the outer baffle plate 315 is convex, and the side of the inner baffle plate 322 away from the outer baffle plate 315 is concave.

[0032] As an embodiment of the utility model, a hanging groove 323 is provided on one side of the hanging plate 321 close to the motor stator, and the hook 311 is arranged on the outer baffle plate 315. The hook 311 is inserted into the hanging groove 323. Through the combination of the hook 311 and the hanging groove 323, the protective cover 31 and the fixing component 32 are combined into a geometric structure, and the hanging groove 323 limits the hook 311 to achieve a fixed connection between the protective cover 31 and the fixing component 32, thereby limiting the protective cover 31, improving the connection strength between the protective cover 31 and the fixing component 32, and avoiding unnecessary falling off of the protective cover 31.

[0033] As an embodiment of the utility model, a snap groove 324 is provided in the hanging groove 323, and a snap head 317 is provided at the end of the hook 311. The snap head 317 is inserted into the snap groove 324. On the basis of the connection between the connecting groove 323 and the hook 311, the snap head 317 and the snap groove 324 are fixed, which can further improve the connection strength between the protective cover 31 and the fixing part 32.

[0034] Preferably, according to specific usage requirements, the snap groove 324 can be set at any position in the hanging groove 323. For example, the snap groove 324 is set on the side of the hanging groove 323 opposite to the motor stator, and accordingly, the snap head 317 is set on the side of the hook 311 away from the motor stator. The combination of the snap groove 324 and the snap head 317 can limit the hook 311 from entering and exiting the hanging groove 323. For example, the snap groove 324 is set on other side surfaces of the hanging groove 323, and accordingly, the snap head 317 is also set on a side close to the snap groove 324. The function of limiting the hook 311 from entering and exiting the hanging groove 323 can also be realized, thereby further improving the connection strength between the protective cover 31 and the fixing component 32.

An additional set of connection components can avoid the protective cover 31 from falling off due to abnormalities in the hook 311, and can effectively improve the connection strength between the fixed component 32 and the protective cover 31.

[0036] As an embodiment of the utility model, a plug-in board 326 extending toward the outer baffle plate 315 is provided on the inner baffle plate 322, and the plug-in port 325 is arranged on the plug-in board 326. Compared with setting the plug-in port 325 on the inner baffle plate 322, the connection strength between the plug-in port 325 and the plug-in column 316 can be improved, and unnecessary influence on the protection of the inner baffle plate 322 can also be avoided.

[0037] As an embodiment of the present invention, a plug-in slot matching the plug-in board 326 is provided on one side of the top plate 312 close to the plug-in board 326. The plug-in slot can limit the plug-in board 326 to a certain extent, and can improve the connection strength between the fixing component 32 and the protective cover 31. Preferably, the plug-in column 316 is arranged inside the plug-in slot, so that the plug-in column 316 is buried inside the plug-in slot to avoid bumping or damage to the plug-in column 316 during installation, and also to avoid unnecessary damage to the operator caused by the plug-in column 316 during the installation process. When the top plate 312 is combined with the plug-in board 326, the plug-in board 326 is first placed in the plug-in slot, and then the plug-in column 316 is aligned with the plug-in interface 325, and finally the plug-in column 316 is inserted into the plug-in interface 325 to complete the combination of the top plate 312 and the plug-in board 326.

[0038] As an embodiment of the utility model, the distance between the plug board 326 and the hanging board 321 is greater than the exposed length of the coil 2, that is, the exposed coil 2 is located between the plug board 326 and the hanging board 321, which can reduce the difficulty of combining the plug board 326 and the top plate 312, and also avoid unnecessary influence on the coil 2 caused by the combination of the protective cover 31 and the fixing part 32.

The base 1 is provided with a plurality of coil protection components 3. The coil protection components 3 are arranged around the exposed coils 2, which can effectively reduce the size of the coil protection components 3 and can be effectively applied to motors with narrow spaces. At the same time, under the premise of not affecting the normal operation of the motor stator, the exposed coils 2 are protected by the coil protection components 3, so that the overall protection of the coils 2 is achieved, thereby improving the reliability and safety of the product.

[0040] As an embodiment of the utility model, the base 1 and the fixing component 32 are integrally formed, which can not only reduce the overall installation difficulty, but also effectively improve the connection strength between the base 1 and the fixing component 32, and at the same time improve the overall uniformity of the motor stator.
