Description

Technical Field

[0001] This utility model belongs to the field of motor housings and refers to a type of motor housing. Background Technology

[0002] An electric motor housing is an outer casing used to mount an electric motor. The motor housing serves many functions and is crucial to the motor. Firstly, it supports and connects the overall structure of the motor, protecting it from various types of damage and contamination. Another purpose of the motor housing is to protect the internal components of the motor from human interference or potential environmental pollution. The design of the motor housing is intended to prevent prying fingers or tools from coming into contact with inductively coupled conductors or rotating cooling fans, thus avoiding damage to electrical or mechanical equipment. They also significantly reduce the risk of internal moisture, dirt, or other contaminants that could harm the working components. Another function of the motor housing is heat dissipation. Heat dissipation surfaces or airflow paths must be installed within the housing to remove heat generated by internal losses, allowing the windings to operate within their rated temperature range.

[0003] The main structure of a motor housing includes a junction box, a housing, and a base. However, in existing motor housing technology solutions, the structure of the motor housing is not simple enough, and the parts are too scattered. In particular, the setting of the junction box will cause the motor housing to occupy a slightly larger volume, making it look somewhat bulky. This will waste some costs during installation, transportation, or storage.

[0004] Therefore, this utility model will propose a solution to the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a motor housing that makes the installation and connection between various components simpler and more integrated, while also providing a more reasonable junction box structure, reducing the size of the motor housing and assembly steps, and reducing installation and transportation costs.

[0006] The purpose of this utility model is achieved as follows: a motor housing, comprising an integrally formed housing and an end cap, the housing being cylindrical and having an arc-shaped upper top surface, the lower part of the housing integrally forming a fixed base, and the upper part of the housing integrally forming a junction box side wall, the junction box side wall and the arc-shaped upper top surface of the housing together forming a wiring space for accommodating the coil.

[0007] In the aforementioned motor housing, the housing is provided with several layers of reinforcing ribs along its length, and the reinforcing ribs extend at least to the peripheral sidewall of the end cover.

[0008] In the aforementioned motor housing, the reinforcing ribs are sheet-like, with the uppermost reinforcing ribs located on both sides of the arc-shaped top surface, together serving as the bottom surface of the wiring space.

[0009] In the aforementioned motor housing, a limiting groove is provided on the inner side of the junction box sidewall, and the limiting groove extends downward to the reinforcing rib on the bottom surface of the wiring space.

[0010] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0011] This utility model features a motor housing with an integrally formed shell and end cap. The top of the arc surface of the shell serves as the bottom of the wiring space, making the installation and connection between the components simpler, more stable, and more integrated. It also features a more rationally designed junction box structure. Compared with the existing technology of separate junction boxes, this reduces the volume of the motor housing and the number of assembly steps, thereby reducing installation and transportation costs.

[0017] The present invention will be further described below with reference to specific embodiments:

[0018] like Figure 1 and 2 As shown, a motor housing includes an integrally formed housing 1 and an end cap 2. The housing 1 is cylindrical and has an arc-shaped upper top surface 11. A fixed base 3 is integrally formed on the lower part of the housing 1, and a junction box sidewall 4 is integrally formed on the upper part of the housing 1. The junction box sidewall 4, together with the arc-shaped upper top surface 11 of the housing 1, forms a wiring space for accommodating the coil. In this technical solution, the housing 1 and the end cap 2 are cylindrical and integrally formed. Compared with the end cap in the prior art, which is fixed by the pitch, the integral end cap 2 in this technical solution is more stable and can reduce installation steps, making assembly more convenient. The cylindrical housing 1 has an arc-shaped periphery, hence the arc-shaped upper top surface 11. (See the attached instruction manual for details.) Figure 1With the arc-shaped top surface 11 as the base, junction box sidewalls 4 extend upwards around the perimeter. The space enclosed by the junction box sidewalls 4 and the arc-shaped top surface 11 is the wiring space. All the wiring and other components required by the motor are housed within the wiring space. The structure is simple and makes full use of the arc-shaped space around the housing 1, resulting in a small volume occupied by the wiring space. Compared with the wiring space solutions in the prior art, it is more convenient for transportation and assembly, and can save costs.

[0019] Furthermore, the housing 1 is provided with several layers of reinforcing ribs 5 along its length. The reinforcing ribs 5 extend at least to the peripheral sidewalls of the end cover 2. The reinforcing ribs 5 are sheet-like, with the uppermost reinforcing rib 5 located on both sides of the arc-shaped upper surface 11, collectively serving as the bottom surface of the wiring space. In this technical solution, the reinforcing ribs 5 extend to the periphery of the end cover 2, further stabilizing the motor housing. Because the reinforcing ribs 5 are sheet-like, the uppermost reinforcing rib 5 can be incorporated into both sides of the arc-shaped upper surface 11 of the housing 1. (See attached instruction manual). Figure 2 It serves as part of the bottom surface of the wiring space, thus preventing dead corners from forming and making it easier to clean and maintain.

[0020] Furthermore, a limiting slot 41 is provided on the inner side of the junction box side wall 4. The limiting slot 41 extends downward to the reinforcing rib 5 on the bottom surface of the wiring space. In this technical solution, the limiting slot 41 can be used to install coil parts of various motors.

[0021] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
