Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a motor with an integrated control box. Background Art

[0002] Existing motors often need to be controlled by a control box, such as a PLC control box, and in most motors, the control box and the motor are generally separate, that is, the control box is not arranged on the motor.

[0003] Of course, in the related art, there are also some motors that directly set the control box on the motor to form a motor with an integrated control box. The motor still has defects in practical applications. As we all know, electrical components are integrated in the control box. These electrical components will generate heat when working, so they need to be cooled when working. However, it is difficult for this kind of motor to fully dissipate the heat of the control box, so it still needs to be improved. Utility Model Content

[0004] In order to solve at least one of the technical problems mentioned in the background technology, the purpose of the present utility model is to provide a motor with an integrated control box.

In this way, when the fan blades that work for motor heat dissipation form airflow (wind) at work, part of the airflow can be blown into the air duct along the outer wall of the motor body and flow along the air duct, so that the heat from the heat dissipation side of the control box can be brought to dissipate the heat of the control box.

[0009] In short, the wind blown out by the fan blades in this solution is used to dissipate heat for the motor body itself and can also dissipate heat for the control box.

[0010] Preferably, the bracket assembly comprises two brackets arranged opposite to each other, and the brackets have surrounding walls extending along the axial direction of the motor body, and the surrounding walls constitute side walls on both sides of the air duct.

[0011] Preferably, the control box spans across the two brackets and is fixed on the top of the two brackets, and the lower side of the control box constitutes a heat dissipation side.

[0012] Preferably, the bracket further comprises a first fixing portion arranged at the lower side of the surrounding wall and a second fixing portion arranged at the upper side of the surrounding wall, the first fixing portion is fixed to the motor body, and the second fixing portion is fixed to the control box.

[0013] Preferably, a plurality of first heat dissipation fins distributed along the circumference of the motor body are provided on the outer wall of the motor body, and the first heat dissipation fins are recessed near the rear end of the motor body to form a circle of concave steps, and the control box is mounted on the concave steps.

[0014] Preferably, the control box comprises a shell and a cover plate, wherein the cover plate covers the shell and constitutes the heat dissipation side.

[0015] Preferably, a plurality of second heat dissipation fins are provided on a side wall of the cover plate away from the shell, and the second heat dissipation fins extend axially along the motor body; and the second heat dissipation fins are located in the air duct.

[0022] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0023] In the following description, terms such as "inside", "outside", "up", "down", "left", "right", etc. that indicate directions or positional relationships are only used to facilitate the description of the embodiments and simplify the description, and do not indicate or imply that the referred device or element must have a specific direction, be constructed and operate in a specific direction. Therefore, it should not be understood as a limitation on the present invention.

[0024] See also Figure 1-5 As shown, the present embodiment provides a motor with an integrated control box 2, comprising a motor body 1 and a control box 2, wherein a wind hood 12 is provided at the rear end of the motor body 1, and fan blades 13 driven by the motor body 1 are provided in the wind hood 12, and the fan blades 13 are encapsulated in the wind hood 12. When the motor is working, the fan blades 13 are driven to rotate, and the movement of the fan blades 13 generates airflow, which flows forward from the air outlet side of the wind hood 12 along the outer wall of the motor body 1 (the end where the main shaft of the motor is located can be considered as the front end) to dissipate heat from the motor.

[0025] In order to improve the heat dissipation effect of the motor body 1 , a plurality of first heat dissipation fins 11 distributed along the circumference of the motor body 1 are provided on the outer wall of the motor body 1 , and the first heat dissipation fins 11 extend along the axial direction of the motor body 1 .

[0026] In order to cooperate with the installation of the wind shield 12, as Figure 4 As shown, the first heat dissipation fin 11 is recessed near the rear end of the motor body 1 to form a circle of concave steps 111, and the air outlet side of the control box 2 is mounted on the concave steps 111, so that the wind generated by the fan blades 13 can flow out from between two adjacent first heat dissipation fins 11 to dissipate heat for the motor body 1.

[0027] The control box 2 is mounted on the motor body 1 through a bracket assembly. Figure 3 As shown, an air duct 4 extending axially along the motor body 1 is formed between the bracket assembly and the motor body 1, and the air outlet side of the wind cover 12 is at least partially facing the air duct 4; the control box 2 includes a heat dissipation side, for example, the bottom of the control box 2 can be used as the heat dissipation side, and the heat dissipation side is at least partially located in the air duct 4.

[0028] In this way, at least part of the airflow formed by the fan blades 13 passes forward from the air duct 4. The airflow advancing in the air duct 4 can take away the heat generated by the heat dissipation side when passing over the heat dissipation side, thereby achieving the purpose of control and heat dissipation.

[0029] It can be seen that when the fan blades 13, which are used for heat dissipation of the motor, form airflow (wind) at work, part of the airflow can be blown into the air duct 4 along the outer wall of the motor body 1 and flow along the air duct 4, so that the heat on the heat dissipation side of the control box 2 can be brought to realize the heat dissipation of the control box 2. In short, the wind blown out by the fan blades 13 in this solution is used to dissipate the heat of the motor body 1 itself and the control box 2.

[0030] The specific structure of the air duct 4 is as follows: Figure 3 As shown, the bracket assembly includes two brackets 3 arranged opposite to each other, and the bracket 3 has a surrounding wall 30 extending along the axial direction of the motor body 1. The surrounding wall 30 constitutes the side walls of the air duct 4 to limit the airflow flowing forward between the two surrounding walls 30.

[0031] The control box 2 spans across the two brackets 3 and is fixed on the top of the two brackets 3. The lower side of the control box 2 constitutes a heat dissipation side. Figure 1 As shown, at this time, the outer wall of the motor body 1, the two surrounding walls 30, and the bottom wall of the control box 2 together form the air duct 4, and the bottom wall of the control box 2 (i.e., the heat dissipation side) constitutes the top wall of the air duct 4.

[0032] The specific structure of the control box 2 in this embodiment is: Figure 5 As shown, the control box 2 includes a shell 22 and a cover plate 21, the cover plate 21 covers the shell 22, and the relevant electrical components are encapsulated between the cover plate 21 and the shell 22; the cover plate 21 constitutes a heat dissipation side; of course, in order to further improve the heat dissipation effect of the control box 2, a side wall of the cover plate 21 away from the shell 22 is provided with a plurality of second heat dissipation fins 211, and the second heat dissipation fins 211 extend axially along the motor body 1; the second heat dissipation fins 211 are located in the air duct 4 (such as Figure 1 as shown).

[0033] The specific structure of the bracket 3 is as follows: Figure 3 As shown, the bracket 3 also includes a first fixing portion 31 arranged on the lower side of the surrounding wall 30 and a second fixing portion 32 arranged on the upper side of the surrounding wall 30. Specifically, the lower side of the surrounding wall 30 is bent inward to form the first fixing portion 31, and the upper side is bent inward to form the second fixing portion 32. During assembly, the first fixing portion 31 is fixed to the motor body 1 by screws, and the second fixing portion 32 is fixed to the control box 2 by bolts and nuts to achieve the installation of the control box 2.

Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
