Description

A positioning structure for condenser motor stator and end cover assembly in automotive air conditioning Technical Field

[0001] This utility model relates to the field of motors, and in particular to an assembly and positioning structure for the stator and end cover of a condenser motor for automotive air conditioning. Background Technology

[0002] In the fields of automotive air conditioning systems and new energy vehicle air conditioning, automotive condenser fans play a crucial role in heat dissipation. Their working principle involves exchanging hot and cold air between components requiring heat dissipation, such as the automotive air conditioning condenser and water tank. A condenser fan mainly consists of a motor, fan blades, and a mounting frame. The motor's stator and end caps are extremely important components; the stator is responsible for conducting the magnetic circuit, and the end caps support the rotating parts.

[0003] However, current motors are mostly designed with a circular structure, which has caused numerous problems during production. During stator and end cover assembly, the lack of a stable positioning method makes them prone to rotation, making assembly extremely difficult and severely impacting production efficiency. The traditional approach to solve this problem is to create a notch in the housing and machine a boss on the end cover, using their cooperation for positioning. However, this method has significant drawbacks: a large gap appears at the connection between the housing notch and the end cover boss, directly reducing the motor's waterproof performance, lowering product reliability and lifespan, and making it difficult to meet the market's demand for high-quality, high-performance automotive air conditioning condenser fans. Therefore, developing a new structure that can solve the stator-end cover assembly rotation problem while improving waterproof performance and facilitating assembly is imperative. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the purpose of this utility model is to provide an assembly and positioning structure for the stator and end cover of a condenser motor for automotive air conditioning.

[0005] To achieve the above and other related objectives, the technical solution provided by this utility model is: a stator and end cover assembly and positioning structure for an automotive air conditioning condenser motor, comprising:

[0006] Stator housing, with a positioning boss on the inner ring of the open end of the stator housing;

[0007] The end cover has an annular protrusion on its bottom side, which corresponds to and matches the inner ring of the open end of the stator housing. The outer ring of the annular protrusion has a positioning groove, which corresponds to and matches the positioning protrusion.

[0008] The preferred technical solution is as follows: the inner ring of the stator housing is detachably installed with multiple sets of stator assembly springs arranged at equal angles, and a stator is assembled between two adjacent sets of stator assembly springs.

[0009] The preferred technical solution is that the end cap has a mounting hole at its center, and the mounting hole contains a bearing for connecting the rotor shaft.

[0010] Due to the application of the above technical solution, the beneficial effects of this utility model are as follows:

[0011] This utility model provides an assembly and positioning structure for the stator and end cover of a condenser motor for automotive air conditioning. By setting a positioning boss on the inner ring of the open end of the stator housing and a positioning groove on the outer ring of the annular boss on the bottom side of the end cover, the surface of the assembled housing no longer has obvious water leakage gaps. This effectively improves the motor's protection performance, reduces the risk of failure due to water ingress, thereby improving the overall quality of the fan product, enhancing its reliability and stability, and extending its service life.

[0017] Example:

[0018] As shown in Figures 1 and 2, according to a general technical concept of this utility model, a stator and end cover assembly and positioning structure for an automotive air conditioning condenser motor is provided, comprising:

[0019] Stator housing 1, with an inner ring positioning boss 11 at the open end of the stator housing 1;

[0020] End cover 2, the bottom side of end cover 2 is provided with an annular boss 21, the annular boss 21 is matched with the inner ring of the open end of the stator housing 1, the outer ring of the annular boss 21 is provided with a positioning groove 22, the positioning groove 22 is matched with the positioning boss 11.

[0021] As shown in Figures 1 and 2, in an exemplary embodiment of this utility model, the inner ring of the stator housing 1 is detachably fitted with multiple sets of stator assembly springs 3 arranged at equal angles, and a stator 4 is assembled between two adjacent sets of stator assembly springs 3.

[0022] As shown in Figures 1 and 2, in an exemplary embodiment of this utility model, the end cap 2 is provided with a mounting hole at its center, and a bearing 5 for connecting the rotor shaft is provided in the mounting hole.

[0023] Therefore, this utility model has the following advantages:

[0024] 1. Improve the quality of fan products: This technical solution changes the traditional design of notches in the casing and bosses in the end caps. Instead, it uses a method of machining bosses in the casing and grooves in the end caps. After assembly, there are no obvious leaks on the surface of the casing, which effectively improves the protection performance of the motor, reduces the risk of failure caused by water ingress, thereby improving the overall quality of the fan products, enhancing the reliability and stability of the products, and extending the service life of the fans.

[0025] 2. Improve the production efficiency of wind turbine installation: The matching and engaging design of the casing boss and the end cover groove enables the stator and end cover to be positioned quickly and accurately during assembly. This avoids the repeated adjustments caused by easy rotation and displacement in traditional methods, greatly simplifies the assembly process, reduces assembly time, and significantly improves the production efficiency of wind turbine installation. This helps companies increase production capacity and meet market demand for products.

[0026] 3. Reduced labor intensity for operators: As the assembly process becomes more convenient and efficient, operators do not need to spend a lot of energy and time dealing with the rotation and displacement of the stator and end cover during assembly. This reduces repetitive and tedious operation steps, thereby reducing the labor intensity of operators, improving the working environment, and helping to improve employee work enthusiasm and work quality.
