Technical Field

[0001] The utility model belongs to the technical field of motor housings, and particularly relates to an integrated motor housing die-casting part. Background Art

[0002] A motor housing die-casting part is a motor housing component manufactured by a die-casting process. A die-casting part is a pressure-cast part. It uses a die-casting machine, a pressure-casting machine equipped with a casting mold, to pour heated liquid metal (such as copper, zinc, aluminum, or aluminum alloy, etc.) into the feed inlet of the die-casting machine. Through the die-casting process of the die-casting machine, a part with the shape and size restricted by the mold is cast. As an important part of the motor, the motor housing die-casting part has multiple important functions.

[0003] In the existing technology, the motor housing die-casting part generally does not have heat dissipation holes. When the motor rotates inside the housing, a large amount of heat energy will be generated. The long-term heat will reduce the service life of the motor. Therefore, we need to perform heat dissipation treatment on the inside of the motor. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems raised in the above background art, and a kind of integrated motor housing die-casting part is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An integrated motor housing die-casting part, including an inner layer housing and an outer layer housing. The annular inner surface of the outer layer housing is fixedly sleeved on the outer surface of the inner layer housing. Four heat dissipation grooves are evenly penetrated and opened on the side surface of the inner layer housing. Multiple reinforcing ribs are fixedly connected to the annular outer surface of the outer layer housing. A placement box is fixedly connected to the outer layer housing evenly. Three mounting rods are fixedly connected to the annular outer surface of the outer layer housing evenly. Triangular steels are symmetrically fixedly connected to the left and right sides of the annular outer surface of the outer layer housing.

[0007] Preferably, a placement groove is opened on the upper surface of the placement box, and a mounting groove is penetrated and opened on the lower surface of the placement groove.

[0008] Preferably, square grooves are opened on the upper surfaces of the three mounting rods, and mounting holes are penetrated and opened on the side surfaces of the three mounting rods.

[0009] Preferably, notch openings are symmetrically penetrated and opened on the upper surface of the triangular steel.

[0010] Preferably, a plurality of heat dissipation holes are penetrated and opened on the connection surface of the inner layer housing and the outer layer housing, and the heat dissipation holes penetrate through the inner walls of the inner layer housing and the outer layer housing.

[0011] Preferably, the placement box is located above the annular surface of the outer shell, the triangular steel is located on both sides below the outer surface of the outer shell, and the three mounting rods are evenly distributed on the annular outer surface of the outer shell.

[0012] Compared with the prior art, the present utility model has the following advantages:

[0013] By providing heat dissipation holes and heat dissipation grooves, the present utility model can dissipate the heat generated inside the motor housing. The heat generated inside the housing during the operation of the motor flows out through the heat dissipation holes, preventing heat concentration from causing component damage and thus affecting the service life of the motor.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The technical solutions in the present utility model will be further described below with reference to the accompanying drawings and embodiments.

[0019] Referring to Figures 1 - 3 , an integrated motor housing die-casting part includes an inner housing 1 and an outer housing 3. The annular inner surface of the outer housing 3 is fixedly sleeved on the outer surface of the inner housing 1. Four heat dissipation grooves 2 are evenly and penetratingly formed on the side surface of the inner housing 1. A plurality of heat dissipation holes 10 are penetratingly formed on the connection surface between the inner housing 1 and the outer housing 3. The heat dissipation holes 10 penetrate through the inner walls of the inner housing 1 and the outer housing 3. When the motor is operating internally, since the motor converts electrical energy into mechanical energy during rotation, a large amount of heat energy will be generated. Part of this heat energy will be carried out by the fan, but there is still part of it that will concentrate inside the motor housing. Therefore, by providing the heat dissipation grooves 2 and the heat dissipation holes 10, a large amount of heat inside the motor housing is dissipated. The heat generated inside the housing during the operation of the motor flows out through the heat dissipation holes, preventing heat concentration from causing component damage and thus affecting the service life of the motor.

[0020] In this utility model, multiple reinforcing ribs 4 are fixedly connected to the annular outer surface of the outer shell 3. The reinforcing ribs 4 can play a role in strengthening and fixing the motor shell to prevent the shell from deforming due to external forces. A placement box 5 is evenly and fixedly connected to the outer shell 3. A placement groove 6 is provided on the upper surface of the placement box 5, and an installation groove 7 is penetratingly provided on the lower surface of the placement groove 6. The placement box 5 is located above the annular surface of the outer shell 3. The placement groove 6 of the placement box 5 is used to store wires and connecting wires. The wires are passed through the installation groove 7 to be connected to the internal wires. When the motor is not in use, the wires are cut and placed in the placement groove for storage, which is convenient for carrying.

[0021] In this utility model, three mounting rods 11 are evenly and fixedly connected to the annular outer surface of the outer shell 3. Square grooves 12 are provided on the upper surfaces of the three mounting rods 11, and mounting holes 13 are penetratingly provided on the sides of the three mounting rods 11. The three mounting rods 11 are evenly distributed on the annular outer surface of the outer shell 3. The motor is connected and installed to other parts of the motor through the mounting holes 11 provided at both ends of the mounting rods 11, making the motor a complete whole.

[0022] In this utility model, triangular steels 8 are symmetrically and fixedly connected to the left and right sides of the annular outer surface of the outer shell 3. Notch openings 9 are symmetrically penetratingly provided on the upper surfaces of the triangular steels 8. The triangular steels 8 are located on both sides below the outer surface of the outer shell 3. The notch openings 9 provided on the triangular steels 8 are for fixing the motor and other fixing parts through bolts. The notch openings 9 are set to be relatively long to prevent the threaded holes from having errors during installation, resulting in inability to install. The bolts can move within the notch openings through the relatively long notch openings 9.

[0023] The functional principle of this utility model can be described through the following operation methods:

[0024] The motor housing die-casting part is divided into an inner shell 1 and an outer shell 3, and it is formed by die-casting. The formed motor housing die-casting part is further processed, such as processing the notch openings 9. The notch openings 9 provided on the triangular steels 8 are for fixing the motor and other fixing parts through bolts. The notch openings 9 are set to be relatively long to prevent the threaded holes from having errors during installation, resulting in inability to install. The bolts can move within the notch openings through the relatively long notch openings 9. For example, heat dissipation grooves 2 and heat dissipation holes 10 are processed. When the motor is working internally, since the motor converts electrical energy into mechanical energy during rotation, a large amount of heat is generated. Part of this heat is taken out by the fan, but part of it will be concentrated inside the motor housing. Therefore, by providing the heat dissipation grooves 2 and heat dissipation holes 10, a large amount of heat inside the motor housing is dissipated. The heat generated inside the outer shell during the operation of the motor flows out through the heat dissipation holes, preventing the heat from concentrating and causing component damage, thereby affecting the service life of the motor.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
