Description

Technical Field

[0001] This utility model relates to the field of motor technology, specifically to a motor magnet fixing structure. Background Technology

[0002] In the field of motor manufacturing, the magnet is a key component of the motor, and its fixing method directly affects the motor's performance, stability, and service life. In current motor structures, the common method for fixing the magnet is to use side panels and retaining springs for abutment fixing (as shown in the attached image). Figure 5 , 6 As shown in the figure, this method only prevents the magnetic tile from moving horizontally, while it can still move vertically. Therefore, in the existing technology, the magnetic tile is fixed by applying glue between the magnetic tile and the motor housing. Although this method can restrict the magnetic tile from moving horizontally and vertically, it requires applying glue, which increases the use of chemicals. The glue can cause harm to the human body, and it also increases manpower, resulting in increased costs. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a motor magnet fixing structure, which solves the problems mentioned in the background.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a motor magnetic tile fixing structure, including a motor housing, a magnetic tile, and a retaining spring. A side fan is connected to the inner side of the motor housing, and a retaining groove is opened at one end of the magnetic tile. The magnetic tile is symmetrically fixed inside the motor housing by the side fan and the retaining spring. After fixing, the magnetic tile cannot move horizontally or vertically inside the motor housing.

[0005] Furthermore, the side fan is symmetrically and integrally connected to the inner side of the motor housing, and the angle between the side fan and the motor housing is at least 15°.

[0006] Furthermore, the slot is a rectangular planar slot, and when the magnetic tile is fixed inside the motor housing, the end of the side fan abuts against the slot.

[0007] Furthermore, one end of the card slot is fixed by a side fan and a card slot, and the other end of the card slot is fixed by the elastic force of a retaining spring.

[0008] Furthermore, the retaining ring is configured with a "U"-shaped structure, and the retaining ring is capable of elastic deformation.

[0009] Furthermore, the motor housing and the magnetic tile have the same curvature, and their adjacent end faces abut each other.

[0010] This utility model provides a motor magnet fixing structure. Compared with the prior art, it has the following advantages:

[0011] This motor magnet fixing structure, through the design of the side fan inside the motor housing engaging with the slot of the magnet, and in conjunction with the spring with elastic deformation capability, achieves stable fixing of the magnet inside the motor housing, preventing it from moving horizontally or vertically. This effectively replaces the traditional glue fixing method, not only reducing manufacturing costs but also reducing the potential health risks to workers caused by glue use, which is more in line with environmental protection concepts and improves the safety and economy of motor manufacturing.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5This utility model provides a technical solution: a motor magnetic tile fixing structure, which consists of a motor housing 1, two magnetic tiles 2, and a retaining spring 3. The motor housing 1 serves as the main structure of the motor and has an internal space for installing and fixing the magnetic tiles 2. The inner side of the motor housing 1 is symmetrically formed by stamping, and the side fan 11 forms an angle of not less than 15° with the motor housing 1. It is used to cooperate with the slot 21 of the magnetic tile 2 to restrict the magnetic tile 2 in the horizontal and vertical positions. The magnetic tile 2 is an important component of the motor, responsible for generating a magnetic field and driving the motor to run. One end of each of the two magnetic tiles 2 is designed with a slot 21. The side fan 11 inside the motor housing 1 is engaged and fixed with the slot 21. The retaining spring 3 is set as a "U"-shaped structure with elastic deformation capability, which is used to cooperate with the side fan 11 to fix the magnetic tile 2 inside the motor housing 1.

[0021] In addition, the slot 21 is designed as a rectangular flat slot, which makes it less likely to fall off when it abuts against the end of the side fan 11.

[0022] Finally, in order to improve the stability of the motor structure design, the motor housing 1 and the magnet 2 have the same curvature and their adjacent end faces abut each other.

[0023] When assembling the motor, two side fans 11 need to be stamped out in the corresponding area of ​​the motor housing 1 first. Then, two magnetic tiles 2 are filled into the inside of the motor housing 1. After filling, it is necessary to ensure that the side fans 11 and the slots 21 at one end of the magnetic tiles 2 engage with each other. Finally, a U-shaped retaining spring 3 is filled into the area between the other ends of the two magnetic tiles 2. Under the action of the spring force of the retaining spring 3, it will resist the magnetic tiles 2. According to the above technical solution, after the magnetic tiles 2 are fixed inside the motor housing 1, they cannot move in either the horizontal or vertical direction. This method replaces the glue bonding method commonly used in the existing technology, which reduces costs and also reduces the problem of glue causing health damage to workers.
