Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a stator housing structure of a motor. Background Art

[0002] As the core power component of various mechanical equipment, the performance and reliability of the motor directly affect the working effect of the entire system. In the construction of the motor, the stator housing is an important component that supports and protects the internal structure of the motor. The traditional motor stator housing is usually made of metal, and the upper and lower shells are connected together by welding. Although welding technology has been widely used in industrial production, there are still several major problems in the manufacturing process of the motor stator housing:

[0003] Unstable welding quality: The welding process is affected by many factors such as operator skills, welding parameters, environmental conditions, etc., which can easily lead to welding defects such as cracks, pores, and lack of fusion, affecting the reliability and safety of the motor.

[0004] Low production efficiency: The welding process requires multiple steps such as preheating, welding, and post-processing. The production cycle is long and the operator's skills are required to be high, which limits the improvement of production efficiency.

[0005] Environmental pollution problem: The welding process will produce pollutants such as smoke, harmful gases, etc., which pose a potential threat to the environment and human health.

[0006] Difficulty in maintenance and disassembly: Once the motor needs to be repaired or parts replaced, the welded stator housing is difficult to disassemble, increasing maintenance costs and time.

[0007] Material waste: Spatter may be generated during the welding process, resulting in material waste and increasing production costs.

[0008] Although there have been some improvement measures for the above problems, such as the use of automated welding equipment and optimization of welding processes, these problems cannot be fundamentally solved. Therefore, developing a new type of motor stator housing connection method that can not only ensure the stability and reliability of the connection, but also improve production efficiency, reduce costs, and reduce environmental pollution has become an important research direction in the motor manufacturing industry.

[0014] When the first engaging protrusion is engaged with the second engaging groove and the second engaging protrusion is engaged with the first engaging groove, the first engaging claw abuts against the second engaging claw.

[0034] Furthermore, the number of the first clamping claws 11 and the number of the second clamping claws 21 are both plural and equal.

[0035] It can be seen from the above description that the number of the plurality of first claws 11 and the second claws 21 is equal and symmetrically distributed, which provides a uniform connection force and ensures the overall balance and stability of the motor stator housing structure.

[0036] Furthermore, a plurality of the first claws 11 are distributed symmetrically on the upper shell 1 ; and a plurality of the second claws 21 are distributed symmetrically on the lower shell 2 .

[0037] It can be seen from the above description that the central symmetrical distribution of the first claw 11 and the second claw 21 further enhances the symmetry and balance of the motor stator housing, and helps to reduce the structural stress caused by improper assembly.

[0038] Furthermore, the first clamping claw 11 is further provided with a first deformation notch 14 , and the first deformation notch 14 is located outside the root of the first clamping protrusion 12 .

[0039] It can be seen from the above description that the design of the first deformation notch 14 allows the first claw 11 to deform appropriately during the clamping process, which helps the clamping protrusion to be inserted into the second clamping groove 23 more easily, thereby improving the convenience of assembly.

[0040] Furthermore, the second clamping claw 21 is further provided with a second deformation notch 24 , and the second deformation notch 24 is located outside the root of the second clamping protrusion 22 .

[0041] It can be seen from the above description that the second deformation notch 24 allows the second claw 21 to deform during the assembly process, so that the second engaging protrusion 22 is more easily engaged with the first engaging groove 13, further improving the assembly efficiency.

[0042] Furthermore, the first claw 11 and the upper shell 1 are an integrally formed one-piece structure.

[0043] It can be seen from the above description that the integrated structure of the first claw 11 and the upper shell 1 reduces the number of parts in the assembly process, simplifies the production process, and helps to reduce manufacturing costs.

[0044] Furthermore, the second claw 21 and the lower shell 2 are an integrally formed one-piece structure.

[0045] It can be seen from the above description that the integrated structure of the second claw 21 and the lower shell 2 reduces the number of parts in the assembly process, simplifies the production process, and helps to reduce manufacturing costs.

[0046] Furthermore, the upper shell 1 is further provided with a first anti-slip protrusion 15 , which is located in the first clamping groove 13 and is used to abut against the outer side wall of the second clamping protrusion 22 .

[0047] As can be seen from the above description, the design of the first anti-dropping protrusion 15 provides an additional anti-dropping mechanism to ensure that the second engaging protrusion 22 is stable in the first engaging groove 13 to prevent the second engaging protrusion 22 from being released due to vibration or impact.

[0048] Furthermore, the lower shell 2 is further provided with a second anti-slip protrusion 25 , which is located in the second clamping groove 23 and is used to abut against the outer side wall of the first clamping protrusion 12 .
