Description

Technical Field

[0001] The invention relates to the technical field of motors, in particular to a dust removal mechanism for a heat sink at the tail of a motor. Background Art

[0002] The electric motor is mainly composed of a stator, a rotor and other accessories. The working principle of the motor is based on the law of electromagnetic induction and the law of electromagnetic force. When the motor converts energy, two components that can move relative to each other are required: one is the component that establishes the excitation magnetic field, and the other is the induced component that induces electromotive force and flows the working current. Of these two components, the stationary part is called the stator and the rotating part is called the rotor. There is an air gap between the stator and the rotor so that the rotor can rotate freely.

[0003] As the motor is used for a long time, the temperature inside the motor increases. However, the existing motor tail is not equipped with a corresponding dust removal component. At the same time, the heat sink at the motor tail will adhere to a lot of dust, resulting in blockage of the heat sink at the motor tail after a long time of use, thereby reducing the heat dissipation efficiency of the motor. Improvements need to be made to this problem. Summary of the invention

[0004] The object of the present invention is to provide a dust removal mechanism for a heat sink at the tail of a motor to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a dust removal mechanism for a heat sink at the tail of a motor, comprising a motor body, a driving assembly, a folding assembly and a cleaning assembly, wherein a motor output shaft is arranged on the front of the motor body, a motor heat sink at the tail of the motor is arranged on the back of the motor body, and a motor cooling fan is arranged on the inner rear side of the motor body.

[0006] Wherein, the driving component comprises: A driving fixed cylinder is fixedly connected to the middle part of the back side of the heat dissipation plate at the tail of the motor. A driving motor is fixedly connected to the middle part of the back side of the driving fixed cylinder. The driving motor has a driving shaft. The driving shaft of the driving motor is fixedly connected to a moving screw. A ball nut pair is threadedly connected to the outer side of the moving screw. A driving frame is fixedly connected to the outer side of the ball nut pair.

[0007] According to the above technical solution, the folding assembly includes a folding frame, a folding rotating block, a folding arm plate, an adjustment frame and a connecting arm plate. The folding frame is fixedly connected to the outside of the driving fixed cylinder, the folding rotating block is rotatably connected to the middle part of the folding frame, the folding arm plate is fixedly connected to the side of the folding rotating block away from the folding frame, the adjustment frame is fixedly connected to the back of the folding arm plate, and the connecting arm plate is rotatably connected to the middle part of the adjusting frame.

[0008] According to the above technical solution, the cleaning component includes an installation groove, a rotating roller, a cleaning roller, a magnetic block 1, a disassembly plate and a limiting plug. The installation groove is opened inside the folding arm plate, the rotating roller is arranged inside the installation groove, and the rotating roller is rotatably connected to the installation groove, the cleaning roller is fixedly connected to the middle part of the rotating roller, the magnetic block 1 is embedded in the back of the folding arm plate, the limiting plug is plugged into the left and right sides of the installation groove, and the disassembly plate is fixedly connected to the back of the limiting plug.

[0009] According to the above technical solution, a connecting rod is fixedly connected to the middle of the back of the motor cooling fan, and the connecting pipe passes through the motor tail heat sink and extends to the back of the motor tail heat sink and is fixedly connected to the front of the driving fixed tube.

[0010] According to the above technical solution, a sliding groove is provided inside the ball nut pair, and the ball nut pair is slidingly connected to the outer wall of the driving fixed cylinder through the sliding groove. The driving shaft of the driving motor passes through the back of the driving fixed cylinder and extends into the driving fixed cylinder to be fixedly connected to the movable screw. The movable screw is rotatably connected to the inner wall of the driving fixed cylinder at one end away from the driving motor, and a rectangular groove is provided on the outside of the driving fixed cylinder to accommodate the rotation of the connecting arm plate.

[0011] According to the above technical solution, the end of the connecting arm plate away from the adjusting frame is rotatably connected to the middle part of the driving frame.

[0012] According to the above technical solution, magnetic blocks 2 are embedded on the top and bottom of the front side of the disassembly plate.

[0013] According to the above technical solution, the number of the driving frame, folding frame, folding rotating block, folding arm plate, adjusting frame and connecting arm plate are two each, and the two driving frames, folding frames, folding rotating block, folding arm plate, adjusting frame and connecting arm plates are symmetrically distributed on the left and right sides of the driving fixed cylinder.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: when the motor body is working, the motor cooling fan at the rear side of the motor body rotates when the motor body is working, and the driving motor is controlled to work, so that the driving motor drives the moving screw to rotate. At this time, the ball nut pair moves forward on the outer side of the moving screw, so that the ball nut pair drives the adjusting frame to move synchronously. When the adjusting frame moves, the adjusting frame squeezes the connecting arm plate, and when the connecting arm plate is squeezed, the adjusting frame is pushed to make the folding arm plate stressed. At the same time, the folding rotating block on the folding arm plate rotates on the inner side of the folding frame outside the driving fixed cylinder, so that the folding rotating block, the folding arm plate and the folding frame are in the same plane. At this time, the cleaning roller contacts the outer surface of the heat dissipation plate at the tail of the motor. With the working of the motor body, the motor cooling fan drives the folding frame to rotate. At the same time, when the folding frame rotates, the cleaning roller rotates and rubs against the outer surface of the heat dissipation plate at the tail of the motor, so that the dust adhering to the surface of the heat dissipation plate at the tail of the motor can be swept away, so that the device can be used for dust removal without stopping, which is more convenient when used. After the dust removal work is completed, the driving motor is controlled to work, so that the driving motor drives the moving screw to rotate, and at the same time the ball nut pair moves backward on the outside of the moving screw, so that the adjustment frame on the ball nut pair pulls the adjustment frame through the connecting arm plate. At this time, the folding rotating block on the folding arm plate rotates in the folding frame, and the folding arm plate gradually rotates and approaches the outer wall of the folding frame, so that the folding arm plate can be folded and stored to avoid blocking the ventilation area of ​​the heat dissipation plate at the tail of the motor, thereby ensuring the overall heat dissipation rate of the motor body; When the cleaning roller needs to be cleaned, the driving motor is controlled to rotate the folding arm plate to be flush with the folding frame. At this time, the disassembly plate is pulled to pull the limiting plug out of the installation slot. At this time, magnetic block 1 is separated from magnetic block 2 on the lower side of the disassembly plate to expose the cleaning roller. By pushing the rotating roller, the rotating roller and the cleaning roller can be taken out of the installation slot as a whole, so that the device can be taken out and cleaned according to the hygiene of the surface of the cleaning roller when in use, so that the device can be cyclically cleaned when in use, and the cleaning roller can be quickly installed and disassembled.
