Description

Technical Field

[0001] The utility model relates to the technical field of motor controllers, in particular to an air-cooled motor controller. Background Art

[0002] A motor controller is a device used to manage the operation of an electric motor. It usually controls the speed, direction and other parameters of the motor by controlling the current and voltage. It is widely used in mechanical motion control in industrial production, drive systems of electric vehicles, and household appliances.

[0003] Existing motor controllers mainly use forced air cooling to dissipate heat, relying on cooling fins to transfer internal heat to the outside. The overall heat dissipation effect is average. At the same time, the exposed idle interfaces of the controller are very easy to enter dust. A large amount of dust accumulation affects the overall operating stability of the controller. In addition, most motor controllers are directly fixed with screws. When disassembly and maintenance are required, disassembly and installation are more difficult in a small installation space. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the heat dissipation effect of the motor controller is average, the idle interface is not sealed and dust is easily accumulated, and it is inconvenient to install and disassemble by bolts and nuts in a small space.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: the utility model proposes an air-cooled motor controller, including a mounting shell and a motor controller body slidably installed inside the mounting shell, the mounting shell is a cavity structure with an opening at the upper end, the bottom wall and two side walls of the mounting shell are provided with exhaust grooves, the front and bottom of the motor controller body are provided with cooling fins, the front of the mounting shell is provided with a heat dissipation window, a heat dissipation bin is installed on the heat dissipation window, the heat dissipation bin is open on both sides, two groups of cooling fans are arranged in the heat dissipation bin, positioning components are also arranged on both sides of the mounting shell, and a dustproof bin is arranged on the rear wall of the mounting shell.

[0006] Preferred technical solution one: the positioning assembly includes a positioning bin, a sliding column, a pulling plate and a limiting plate. The positioning bin is arranged on both side walls of the mounting shell and close to the top. The sliding column passes through and is slidably arranged on the positioning bin. The sliding column is located in the positioning bin and is provided with a boss. A spring is sleeved on the sliding column. The two ends of the spring are respectively connected to the boss and the inner wall of the positioning bin. The sliding column is symmetrically provided with two groups. The pulling plate and the limiting plate are respectively arranged on both sides of the sliding column. One end of the limiting plate is chamfered to facilitate pressing the motor controller into the mounting shell.

[0007] Preferred technical solution two: a sealed door is hingedly provided on the top of the dustproof bin, and a socket window is hingedly provided on the rear wall of the dustproof bin. When in use, the sealed door is opened so that the wiring terminal of the motor controller body is located inside the dustproof bin, and then the sealed door is closed. To use a specific wiring terminal, only the corresponding socket window needs to be opened.

[0008] Preferred technical solution three: mounting side panels are provided on both sides of the mounting shell, and bolt fixing holes are provided on the mounting side panels.

[0009] Preferred technical solution four: cooling air holes are evenly distributed on the heat dissipation fins.

[0010] Preferred technical solution five: the opening of the heat dissipation bin is set to correspond to the size of the heat dissipation window, and a dustproof net is provided at the opening of the heat dissipation bin.

[0011] The utility model proposes an air-cooled motor controller, which adopts the above structure to achieve the following beneficial effects:

[0012] (1) The motor controller body is installed inside the mounting shell through a positioning assembly, so that the motor controller body has good protection and is easy to install and disassemble. At the same time, the heat dissipation bin and the two sets of internal heat dissipation fans can efficiently dissipate the heat from the heat dissipation fins, thereby increasing the heat dissipation efficiency;

[0013] (2) The dustproof bin can effectively prevent dust from reaching the wiring terminals of the motor controller, and at the same time, it still has good protection when connecting to the external wiring. BRIEF DESCRIPTION OF THE DRAWINGS
