The motor base assembly of the above embodiment can also be used in the technical field of air conditioners, that is, according to another aspect of the present invention, an air conditioner is provided. The air conditioner includes a motor base assembly. The motor base assembly is the motor base assembly in the above embodiment.

In this embodiment, different steps, that is, the first connection component and the second connection component, are provided in the opening direction of the cylindrical cavity of the motor base. A set of multiple motor fixing screw columns, that is, connection posts, are designed on the same step. Multiple sets of screw columns are used to install motors of different thicknesses, and by rotating a certain angle to achieve the universality of the motor pressure plate, the manufacturing cost is reduced and the production efficiency is improved.

In the prior art, the motor base in the air conditioner is detachably installed on the base, and the motor base is integrally formed into a cylindrical motor cavity with one end completely open, and the other end of the cavity is provided with a groove for the front rubber ring of the motor to support the motor It blocks the axial and radial movement of the motor. The motor is installed in the motor cavity. The motor pressure plate contains a flanged hole and a boss. The center of the hole and the boss coincides with the center of the motor apron groove. The motor pressure plate passes through the screw. Lock on the motor base, so that the rubber rings on both sides of the motor are pressed and fixed. At present, only one motor of one thickness can be installed on one motor base. When designing and manufacturing a wall-mounted air conditioner, different power motors are required according to the energy efficiency of the air conditioner. Different motors have the same diameter and different thickness. As a result, the manufacturing cost of air conditioners increases, the versatility of materials decreases, and the production efficiency is not high.

As shown in Figure 2, in order to ensure the strength of the thicker motor screw column and meet the air conditioner assembly requirements, the motor base is designed according to the thicker motor, and a set of three is set at an appropriate position according to the motor thickness to match the motor pressure plate The fixed screw columns of these screws and the end surface of the motor pressure plate are on the same step surface, that is, the first step surface, so that the entire motor pressure plate sheet metal part can be designed as a plane, which is beneficial to simplify the structure of the sheet metal part. When the thickness of the motor is thin, another set of three fixed screw columns matching the motor pressure plate are provided at appropriate positions according to the thickness of the motor. The end surfaces of these fixed screw columns and the motor pressure plate are on the other step surface, that is, the first On the two-step surface, at this time, the motor pressure plate has only been rotated at a certain angle, and no structural changes have been made. In this way, it has reached the universality of the motor pressure plate. When the motor is thick, lock the motor pressure plate to the three screw posts on the first step surface. The specific assembly diagram is shown in Figure 3. When the thickness of the motor is thin, lock the motor pressure plate to the three screw posts on the second step surface. The specific assembly diagram is shown in Figure 4. In this design, regardless of the thickness of the motor, the motor shaft extends from the motor seat in the same position, ensuring the minimum shaft length of the motor and improving the motor efficiency as much as possible. The motor base is designed with multiple sets of screw posts on different step surfaces, and the end surfaces of each set of screw posts and the motor pressure plate are on the same step surface, which achieves the installation and reliability of motors with different thicknesses, which meets the energy efficiency requirements of air conditioners. The universality of the motor base and the motor pressure plate is realized, the production cost is reduced, and the production efficiency is improved. Among them, for several motors with a small difference in thickness gradient, in order to meet the structural strength and air conditioning assembly requirements, the motor base can also be designed according to the motor with a smaller thickness, so that for thinner motors, the motor pressure plate is locked at the first On the three screw columns on a step surface, for a thicker motor, the motor pressure plate is locked on the three screw columns on the second step surface, and the depth of the cylindrical cavity where the second step surface is located is greater than The first step surface.
