Description

Technical Field

[0001] The utility model belongs to the technical field of motor accessories, and in particular relates to a motor housing that is easy to dissipate heat. Background Art

[0002] The motor will generate significant heat during operation. If the heat is not dissipated in time and effectively, it will cause internal temperature rise, which will have an adverse effect on the performance and service life of the motor. Traditional motor housing design often only opens heat dissipation ports on the surface of the housing and relies on natural convection to dissipate heat. Although this method is simple and easy, its heat dissipation efficiency is seriously affected by external factors such as ambient temperature and wind speed, and the heat dissipation effect is limited. Utility Model Content

[0003] To solve the problems raised in the above background technology. The utility model provides a motor housing that is easy to dissipate heat, including a housing body, characterized in that: the housing body includes an end cover and a protective shell for mounting a stator and a rotor, the end of the protective shell is connected to the end cover, the outer wall of the protective shell is evenly distributed with heat dissipation ports, the end of the protective shell away from the end cover is connected to a compensation cover, the compensation cover is connected to the inner cavity of the protective shell, an impeller is connected inside the compensation cover, an end of the impeller adjacent to the end cover is provided with an assembly groove, the outer wall of the compensation cover is provided with an air inlet groove, and the air inlet groove is evenly distributed with air inlet holes.

[0004] Furthermore, a boss is provided at one end of the protective shell away from the end cover, the compensation cover shell is connected with the protective shell through the boss, a limiting opening and an air inlet channel are provided on the boss, the limiting opening is located in the air inlet channel and the central axis is aligned with the assembly groove.

[0005] Furthermore, the assembly groove is in the shape of a trumpet opening, and the compensation cover is threadedly connected to the boss.

[0006] Furthermore, a butt ring is arranged in the compensation housing, and the butt ring is in abutment with the end of the boss.

[0007] Furthermore, the outer wall of the air inlet slot is connected with a filter.

[0008] Furthermore, the heat dissipation port is obliquely arranged on the outer wall of the protective shell.

[0009] The beneficial effects of the utility model are as follows: the heat dissipation port is tilted on the outer wall of the protective shell, which is conducive to changing the direction of the heat dissipation airflow and enhancing the heat dissipation effect. When the airflow is ejected from the heat dissipation port, due to the existence of the tilt angle, the airflow will form a certain vortex on the surface of the protective shell, increasing the contact time between the airflow and the protective shell, thereby more effectively taking away the heat from the surface of the protective shell. At the same time, the tilted heat dissipation port can also prevent impurities such as dust and moisture from directly entering the interior of the protective shell, playing a certain protective role; through the modular design and the heat dissipation method directly connected to the rotor, efficient heat dissipation of the motor is achieved, and the stability and reliability of the motor are improved. At the same time, the design also has the advantages of environmental protection and recyclability, which conforms to the concept of modern industrial design. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-7The utility model provides the following technical solutions: a housing of a motor that is easy to dissipate heat, comprising a housing body, characterized in that: the housing body comprises an end cover 1 and a protective shell 2 for mounting a stator and a rotor, the end of the protective shell 2 is connected to the end cover 1, and the outer wall of the protective shell 2 is evenly provided with heat dissipation ports 3, the end of the protective shell 2 away from the end cover 1 is connected to a compensation cover 4, the compensation cover 4 is communicated with the inner cavity of the protective shell 2, an impeller 5 is connected inside the compensation cover 4, an end of the impeller 5 adjacent to the end cover 1 is provided with an assembly groove 6, an outer wall of the compensation cover 4 is provided with an air inlet groove 7, and air inlet holes 8 are evenly distributed on the air inlet groove 7; a boss 9 is provided at one end of the protective shell 2 away from the end cover 1, the compensation cover 4 body is communicated with the protective shell 2 through the boss 9, a limited opening 10 and an air inlet channel 11 are provided on the boss 9, the limited opening 10 is located in the air inlet channel 11 and the central axis is aligned with the assembly groove 6.

[0020] With the above structure, the boss 9 is provided to facilitate the connection between the compensation cover 4 and the protective shell 2, and the assembly is more convenient; the rotor passes through the limit opening 10, and the limit opening 10 has the technical effect of limiting the freedom of the rotor; the rotor drives the impeller 5 to rotate, and the air enters the compensation cover 4 from the air inlet 8. Driven by the impeller 5, the low-temperature air moves toward the protective shell 2 through the air inlet channel 11, and the low-temperature air exchanges heat to take away the heat, and finally ejects it from the heat dissipation port 3; compared with the existing products, the technical solution does not need to add a fan for heat dissipation by directly connecting the impeller 5 to the rotor; when the motor is damaged, the compensation cover 4 can be partially removed and reused, which improves the recyclability of the components and is more environmentally friendly; on the contrary, when the compensation cover 4 is partially damaged, it only needs to be replaced evenly to complete the repair; the modular structural design effectively improves the recyclability of the components.

[0021] In this embodiment, the assembly groove 6 is in the shape of a trumpet opening, and the compensation housing 4 is threadedly connected to the boss 9 .

[0022] With the above structure, the compensation housing 4 is threadedly connected to the boss 9. As the connection continues, the rotor is gradually inserted into the assembly groove 6. The trumpet-shaped assembly groove 6 can be interference-fitted with the assembly to ensure that the rotor can drive the impeller 5 to rotate.

[0023] In this embodiment, a butt ring 12 is disposed in the compensation housing 4 , and the butt ring 12 abuts against the end of the boss 9 .

[0024] With the above structure, when the end of the boss 9 abuts against the retaining ring 12, the rotor is connected to the assembly groove 6 in place, which makes it easy for the assembler to judge whether the rotor is connected to the assembly groove 6 in place by feel.

[0025] In this embodiment, the outer wall of the air inlet slot 7 is connected with a filter screen 13 .

[0026] With the above structure, the filter 13 is used to block dust and impurities in the air, reducing the impurities from entering the protective shell 2, thereby avoiding contamination of the rotor or the stator.

[0027] In this embodiment, the heat dissipation opening 3 is obliquely arranged on the outer wall of the protective shell 2 .

[0028] The heat dissipation opening 3 is obliquely arranged on the outer wall of the protective shell 2, which is beneficial to changing the direction of the heat dissipation airflow and enhancing the heat dissipation effect.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
