Technical Field

[0001] This utility model relates to a gearbox housing structure, specifically a gearbox housing structure for an automotive air conditioning system. Background Technology

[0002] The automotive air conditioning gearbox refers to the mechanical component in an automotive air conditioning system used to transmit and regulate the flow of refrigerant. Its main function is to control the flow speed and direction of refrigerant by changing the rotation speed and direction of the gears, thereby realizing the cooling or heating function of the air conditioning system.

[0003] In existing automotive air conditioning gearboxes, the iron shaft is usually installed and fixed only by magnets. However, the effect of magnets is limited. In actual use, the end of the iron shaft may become unstable, resulting in a decrease in the precision of the gearbox. Utility Model Content

[0004] The purpose of this utility model is to provide a housing structure for an automotive air conditioning gearbox. Through the central seat and the upper convex seat, the stability of the main internal structure of the automotive air conditioning gearbox housing structure is enhanced, ensuring the stability of the iron shaft during operation and improving the precision of the gearbox.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a car air conditioning gearbox housing structure, including a housing and a housing base. The housing base is a cavity structure with openings at both ends and a hollow interior. An iron shaft and a magnet are disposed inside the cavity of the housing base. The iron shaft is installed inside the magnet. The magnet includes a main body and a lower edge seat disposed below the main body. A base cover is disposed below the iron shaft. The base cover includes a central seat and an upper protrusion seat disposed on the central seat. Both the central seat and the upper protrusion seat abut against the lower edge seat, so that the base cover provides better support for the magnet, making the structure of the magnet and the iron shaft inside it more stable.

[0006] Preferably, the housing is a cavity structure with an opening at one end and a hollow interior, and the base is fixed inside the cavity of the housing.

[0007] Preferably, the base cover also includes an extension platform, which is fixed to the outer circle of the center seat.

[0008] Preferably, the extension platform is fixed to the lower end face of the housing, so that the extension platform supports the lower end face of the housing and ensures the stability of the housing.

[0009] Preferably, an installation groove is provided on the upper end face of the upper protrusion, and the bottom of the iron shaft is fixed in the installation groove. The installation depth of the iron shaft in the installation groove can be determined as needed, so that the length of the iron shaft can be adjusted to meet more different needs.

[0010] Preferably, the two ends of the iron shaft abut against the main body and the mounting groove respectively, so that the upper and lower ends of the iron shaft are both limited, ensuring the stability of the iron shaft structure.

[0011] Preferably, the main body is fixed inside the cavity of the housing, so that the main body maintains structural stability under the action of the housing and the base cover.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting a central seat and an upper convex seat, fully contacts and supports the magnet, ensuring the stability of the magnet. At the same time, the upper convex seat fixes and supports the iron shaft. Therefore, the design of the central seat and the upper convex seat enhances the stability of the main internal structure of the automotive air conditioning gearbox housing, ensures the stability of the iron shaft during operation, and improves the precision of the gearbox.

[0014] 2. This utility model, by setting an installation groove on the upper protrusion, allows the installation depth of the iron shaft in the installation groove to be adjusted as needed, thereby adapting to different installation requirements and increasing the applicability in actual use.
