Description

Technical Field

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

[0002] The motor is generally composed of a stator, a rotor, a motor housing and other components. In order to facilitate assembly, the motor housing of a traditional motor is generally divided into an upper motor housing and a lower motor housing. The following problems exist during the manufacturing and installation process:

[0003] 1. Usually, in order to accommodate the stator and the rotor inside the motor housing, a corresponding accommodation cavity is formed inside the motor housing, and the motor housing is usually made of one-piece molding, so the material of the motor housing needs to have a large tensile performance, and at the same time, the bearing holes on the upper and lower motor housings need to maintain a concentric position during the installation process, which makes the production of the motor housing not only cumbersome but also requires high molding accuracy;

[0004] 2. In addition, when installing the two ends of the stator into the inner cavity of the upper motor housing and the lower motor housing, it is necessary to use external tools to press the upper motor housing and the lower motor housing into the two ends of the stator respectively. In addition, when the upper motor housing and the lower motor housing are pressed into the installation process with the help of external tools, it is also necessary to always pay attention to whether the connection holes on the upper motor housing and the lower motor housing are aligned. Therefore, the installation process is relatively cumbersome and difficult to install.

[0005] 3. After the traditional upper motor housing and the lower motor housing are installed in place, the two form an almost closed space. The heat generated by the motor during use is difficult to dissipate, resulting in poor heat dissipation performance. Utility Model Content

[0006] In view of the defects existing in the prior art, the purpose of the utility model is to provide a motor mounting housing which is simple to manufacture and quick to install.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0009] Furthermore, the upper connecting column includes a first upper connecting column and a second upper connecting column, one end of the first upper connecting column extends vertically downward from the outer edge of the end surface of the upper motor housing body, and the second upper connecting column extends vertically downward from the other end of the first upper connecting column, wherein the outer diameter of the first upper connecting column is greater than the outer diameter of the second upper connecting column.

[0010] Furthermore, the lower connecting column includes a first lower connecting column and a second lower connecting column, one end of the first lower connecting column extends vertically upward from the outer edge of the end surface of the lower motor housing body, and the second lower connecting column extends vertically upward from the other end of the first lower connecting column, wherein the outer diameter of the first lower connecting column is larger than the outer diameter of the second lower connecting column.

[0011] Furthermore, a plurality of connecting plates are arranged around the outer edge of the upper mounting hole and are connected to the plurality of upper connecting columns, and a gap is arranged between an adjacent pair of connecting plates.

[0012] Furthermore, upper reinforcing ribs arranged along the length direction of the connecting plate are also provided on the end surface of the connecting plate.

[0014] Furthermore, a lower reinforcing rib is provided between the outer edge of the lower mounting hole and the lower connecting column.

[0015] The beneficial effects of the utility model are as follows: by correspondingly arranging upper connecting columns and lower connecting columns on the upper motor housing and the lower motor housing respectively, the upper and lower ends of the motor stator are positioned and installed by the upper connecting columns and the lower connecting columns respectively, so that the installation and assembly process of the motor adopting this motor housing structure is very convenient and quick. At the same time, since the connecting columns are used to position, support and install the stator of the motor, there is no need to stretch the motor housing, so the motor housing can be made of a material with higher hardness, and the rigidity of the motor housing is better. In addition, the setting of the connecting columns improves the rigidity of the electromechanical housing; in addition, the hollow setting around the motor housing is more conducive to the heat dissipation of the motor.

DETAILED DESCRIPTION

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] See attached Figure 1 As shown, this embodiment provides a motor mounting housing 100, which includes an upper motor housing 1 and a lower motor housing 2. When installed, the upper motor housing 1 and the lower motor housing 2 are arranged opposite to each other in an upper and lower direction, and the stator module on the motor is installed between the upper motor housing 1 and the lower motor housing 2.

[0025] Refer to the attached Figure 2 and 3 As shown, the lower motor housing 2 includes a lower motor housing body 21 that is approximately disc-shaped, and a lower mounting hole 23 for matching and mounting with the motor rotor is formed at the center of the lower motor housing body 21. At the same time, lower connecting columns 22 extending upward are correspondingly arranged at the four sides of the end surface of the lower motor housing body 21. The number of the lower connecting columns 22 is not limited, and the function of the lower connecting columns 22 is to provide support for the installation of the rotor and stator of the motor. In one embodiment, the number of the lower connecting columns is four, and the four lower connecting columns are evenly arranged around the end surface of the lower motor housing body 21.

[0026] Continue to refer to the attached Figure 2 and 3As shown, in order to facilitate the installation of the motor stator module 200 on the lower connecting column 22, the lower connecting column 22 is formed by two parts, namely a cylindrical first lower connecting column 221 and a second lower connecting column 222, one end of the first lower connecting column 221 extends vertically upward from the end surface of the lower motor housing body 21, and the second lower connecting column 222 extends vertically upward from the other end of the first lower connecting column 221, and at the same time, the outer diameter of the first lower connecting column 221 is larger than the outer diameter of the second lower connecting column 222, so that a step-shaped step portion is formed at the connection between the second lower connecting column 222 and the first lower connecting column 221, and correspondingly, a mounting hole is formed at the lower end surface of the motor stator module, and the aperture size of the mounting hole matches the outer diameter size of the second lower connecting column 222, so that when the second lower connecting column 222 is installed in the mounting hole at the lower end surface of the motor stator module, when the second lower connecting column 222 can no longer continue to move along the mounting hole, it indicates that the second lower connecting column 222 has been installed in place. In one embodiment, a lower reinforcing rib 25 is disposed between the outer edge of the mounting hole and the lower connecting column 22 .

[0027] Continue to refer to the attached Figure 2 and 3 As shown, openings 24 are arranged around the outer edge of the lower mounting hole 23, and the plurality of openings 24 are evenly spaced along the circumferential direction of the outer edge of the mounting hole. The arrangement of the openings 24 can provide heat dissipation capacity for the motor. In one embodiment, the opening size of the openings 24 is gradual, that is, the opening size of the openings 24 near the lower mounting hole 23 is smaller, and the opening size of the openings 24 far from the lower mounting hole 23 is larger.

[0028] Refer to the attached Figure 4 and 5 As shown, the upper motor housing 1 includes an upper motor housing body 11, and an upper mounting hole 13 is formed at the center of the upper motor housing body 11. When the upper motor housing is installed, the upper mounting hole 13 is in a concentric position with the lower mounting hole 23 on the lower motor housing body 21. Correspondingly, upper connecting columns 12 are formed on the end surface of the upper motor housing body 11, and the number and position of the upper connecting columns on the lower motor housing body 21 correspond to each other.

[0029] The structure of the upper connecting column 12 is the same as that of the lower connecting column, that is, the upper connecting column 12 includes a first upper connecting column 121 and a second upper connecting column 122, one end of the first upper connecting column 121 extends vertically downward from the outer edge of the end surface of the upper motor housing body 11, and the second upper connecting column 122 extends vertically downward from the other end of the first upper connecting column 121. Similarly, the outer diameter of the first upper connecting column 121 is greater than the outer diameter of the second upper connecting column 122, and a step-shaped step portion is formed at the connection between the second upper connecting column 122 and the first upper connecting column 121, so that when the second upper connecting column 122 is installed in the mounting hole at the upper end surface of the motor stator module, when the second upper connecting column 122 can no longer continue to move along the mounting hole, it indicates that the second upper connecting column 122 has been installed in place.

[0030] Continue to refer to the attached Figure 4 and 5 As shown, a strip-shaped connecting plate 14 is formed between the upper connecting column and the upper mounting hole 13, and a notch 15 is formed between two adjacent connecting plates 14. The presence of the notch 15 can effectively improve the heat dissipation performance inside the motor. In addition, in order to further improve the connection strength between the upper connecting column and the mounting hole, an upper reinforcing rib 16 is also formed at the end surface of the connecting plate 14.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include these modifications and variations.
