Description

Technical Field

[0001] The present invention relates to the technical field of drive motors, and in particular to a two-in-one structure of a motor and a controller that is compatible with both self-cooling and forced air cooling. Background Art

[0002] The two-in-one motor and controller structure, compatible with both self-cooling and forced air cooling, integrates the motor and controller into a single unit, reducing wiring complexity and space requirements. This helps reduce overall system costs and simplifies installation and maintenance.

[0003] However, during the actual installation and use of the existing two-in-one drive motor, the installation position of the motor on the equipment or the installation position of the motor equipment body will block the fixed air outlet position or air inlet position of the traditional air-cooled heat dissipation structure, resulting in the existing two-in-one drive motor being inconvenient to avoid affecting the heat dissipation effect by adjusting the position of the heat dissipation mechanism and the air inlet and outlet correspondingly with the installation position during installation. On the other hand, when the heat dissipation fin structure in the existing heat dissipation mechanism has limited installation space and a relatively small design volume, simply increasing the number of heat dissipation fins or the exposed area of the fins will have limited enhancement effect under the heat dissipation of a fixed-power heat dissipation fan. The traditional liquid circulation cooling effect is better, but the overall mechanism connection pipe volume is larger and more complicated, which is inconvenient to install and use. As a result, the heat dissipation mechanism in the current two-in-one drive motor is not convenient to enhance the heat dissipation effect of the controller circuit board by simplifying the traditional liquid circulation cooling mechanism in combination with the heat dissipation fins.

[0034] Example 1: Please refer to Figures 1-12 The present invention provides a technical solution: a two-in-one structure of a motor and a controller compatible with self-cooling and forced air cooling, a heat dissipation shell 2 is installed on the left end of the driving motor 1, and the left end of the heat dissipation shell 2 is connected to the mounting shell 3, and an adjustment frame 6 is rotatably installed in the inner cavity of the heat dissipation shell 2, and the left end of the rotor of the driving motor 1 is connected to the transmission column 5 through the docking block 4 and the concave-convex connection mechanism, and the transmission column 5 is installed between the heat dissipation shell 2 and the adjustment frame 6 through a bearing, and mounting strips 7 are fixed on both sides of the front and rear sides of the left inner wall of the groove of the adjustment frame 6, and the outer sides of the two mounting strips 7 are connected to the No. 1 gear ring 8 through bearings, and a heat dissipation fan 9 is connected to the outer side of the No. 1 gear ring 8, and the inner cavity of the heat dissipation shell 2 is designed to be a circular structure, and the circular inner cavity of the heat dissipation shell 2 is used for rotation adjustment of the adjustment frame 6, and circular holes are opened on the front and rear sides of the adjustment frame 6, and the circular holes of the adjustment frame 6 are used for the installation of the heat dissipation fan 9, and the right side of the No. 1 gear ring 8 is meshed with the No. 2 gear ring 10, which is fixed on the outer side of the transmission column 5 and the inner groove of the adjustment frame 6. A heat sink 11 is installed on the side, and circular grooves are provided on the front and rear sides of the heat sink 11. The circular grooves of the heat sink 11 correspond to the positions of the circular holes of the adjustment frame 6. The notch on the right side of the circular groove of the heat sink 11 is used for connecting the No. 1 gear ring 8 with the No. 2 gear ring 10. Heat dissipation aluminum fins are arranged equidistantly between the grooves on the front and rear sides of the heat sink 11. The heat dissipation aluminum fins of the heat sink 11 are designed to be a hollow structure. A lever 15 is installed on the left front side of the adjustment frame 6. Holes are equidistantly provided on the outer side of the heat sink 2. The holes on the outer side of the heat sink 2 are used for air intake and heat dissipation. A notch is provided on the left side of the holes on the outer side of the heat sink 2. The notch of the heat sink 2 is used for sliding of the lever 15. A connecting plate 12 is fixed to the left end of the transmission column 5. A heat sink 14 is sealed and rotatably connected to the left side of the connecting plate 12. The heat sink 14 is installed on the controller circuit board in the mounting shell 3. A heat dissipation component 16 is provided between the heat sink 14 and the heat sink 11. The heat dissipation component 16 is used for circulating heat dissipation of the heat sink 14;

[0035] According to the installation position of the drive motor 1 on the equipment or the installation position of the equipment with the drive motor 1, the positions of the adjustment frame 6 and the heat sink 11 in the heat dissipation shell 2 are adjusted, and the positions of the two heat dissipation fans 9 are adjusted synchronously, so that the positions of the two heat dissipation fans 9 are adjusted to a position where there is no obstruction or is conducive to air circulation. Then, the transmission column 5 and the second gear ring 10 are driven to rotate through the docking block 4. When the second gear ring 10 rotates, the meshed first gear ring 8 on both sides rotates oppositely, so that the two heat dissipation fans 9 rotate accordingly, and form an air inlet and an air outlet. The airflow from the air inlet passes through the heat sink 11 and is blown out from the air outlet. In this process, the heat in the heat dissipation shell 2 and the mounting shell 3 is dissipated through the flow of air.

[0036] Example 2: Based on Example 1, please refer to Figures 1-15 , the heat dissipation assembly 16 is arranged between the heat dissipation seat 14 and the heat dissipation body 11, the heat dissipation assembly 16 includes a first groove 161 and a second groove 162, the first groove 161 is opened at the center position on the right side of the heat dissipation seat 14, the second groove 162 is opened on the outside of the first groove 161, the inside of the first groove 161 is rotatably connected to the central convex column on the left side of the connecting plate 12, and the second groove 162 is sealed and rotatably connected with a rotating column 163. The rotating column 163 is rotatably installed at the opening position on the left side of the connecting plate 12 through a bearing. A third groove 164 is opened in the convex body on the front side of the heat dissipation seat 14, and the second groove 162 is divided into two upper and lower adjustable chambers by a slider 165 and a rotating column 163. The two adjustable chambers separated in the second groove 162 are respectively connected to the third groove The groove 164 corresponds to the upper and lower connecting holes where the second groove 162 passes through. The inner cavity of the third groove 164 is slidably connected to a slider 165 through a spring. The third groove 164 and the second groove 162 are connected to each other. The slider 165 slides in the third groove 164 and the second groove 162. Connecting holes are provided on both the upper and lower sides of the connection between the second groove 162 and the third groove 164. A heat dissipation chamber 166 and the second groove 162 are filled with heat dissipation liquid. The inner cavity of the second groove 162 is connected to the heat dissipation chamber 166 through two hoses. The heat dissipation chamber 166 is opened on the inner side of the heat sink 11. The inner side of the heat dissipation chamber 166 is connected to the hollow structure of the heat dissipation aluminum fins of the heat sink 11. The heat dissipation assembly 16 is used for circulating heat dissipation of the heat sink 14.

[0037] During the rotation of the transmission column 5, the connecting plate 12 is synchronously driven to rotate in a sealed manner on the right side of the heat sink 14. During this process, the central protrusion on the left side of the connecting plate 12 rotates in the first groove 161, and the rotating column 163 rotates in the second groove 162, so that the cavity on one side between the rotating column 163 and the slider 165 gradually becomes smaller. The rotating column 163 squeezes the heat dissipation liquid in the smaller cavity between the rotating column 163 and the slider 165 into the heat dissipation chamber 166 through the corresponding connecting hole in the second groove 162, and squeezes the cooled heat dissipation liquid in the heat dissipation chamber 166 into the heat dissipation chamber 166 from the other corresponding connecting hole in the second groove 162. In the enlarged cavity on the other side between the rotating post 163 and the slider 165, when the rotating post 163 rotates and contacts the slider 165 and rotates on its own, the slider 165 squeezes the spring forward and moves into the third groove 164. When the rotating post 163 rotates over the slider 165, the slider 165 quickly moves backward and resets in the third groove 164 as the spring returns, so that two chambers are always formed in the second groove 162. The rotating post 163 that cooperates with the rotation of the second groove 162 causes the heat dissipation liquid in the second groove 162 and the heat dissipation chamber 166 to circulate and replace, thereby completing continuous heat dissipation of the heat sink 14.

[0038] Working Principle: When using this two-in-one motor and controller structure that is compatible with both self-cooling and forced air cooling, the installer rotates and adjusts the position of the lever 15 by observing the installation position of the drive motor 1 on the equipment or according to the installation position of the equipment with the drive motor 1. The rotating lever 15 drives the adjustment frame 6 and the heat sink 11 to rotate and adjust their positions within the heat sink housing 2, so that the two cooling fans 9 are adjusted relative to each other. When the two fans are adjusted to a position without obstructions or conducive to air circulation, the position adjustment of the cooling fans 9 is completed.

[0039] When the drive motor 1 starts working, the rotor of the drive motor 1 drives the transmission column 5 through the docking block 4 and the concave-convex connection mechanism. During the rotation between the heat dissipation shell 2 and the adjustment frame 6, the transmission column 5 synchronously drives the second gear ring 10 to rotate. When the second gear ring 10 rotates, the meshed first gear rings 8 on both sides rotate in the opposite direction, causing the two cooling fans 9 to rotate accordingly and form an air inlet and an air outlet. The airflow from the inlet passes through the heat sink 11 and is then blown out from the air outlet. In this process, the heat in the heat dissipation shell 2 and the mounting shell 3, as well as the heat on the heat sink 11, is brought out by the flow of airflow to achieve cooling.

[0040] At the same time, during the rotation of the transmission column 5, the connecting plate 12 is synchronously driven to rotate in a sealed manner on the right side of the heat sink 14. During this process, the central protrusion on the left side of the connecting plate 12 rotates in the first groove 161, and the rotating column 163 rotates in the second groove 162, so that the cavity on one side between the rotating column 163 and the slider 165 gradually becomes smaller. The rotating column 163 squeezes the heat dissipation liquid in the smaller cavity between the rotating column 163 and the slider 165 into the heat dissipation chamber 166 through the corresponding connecting hole in the second groove 162, and squeezes the cooled heat dissipation liquid in the heat dissipation chamber 166 into the larger cavity on the other side between the rotating column 163 and the slider 165 from another corresponding connecting hole in the second groove 162. When the rotating column 163 rotates, When the rotary column 163 contacts the slider 165 and rotates, the slider 165 squeezes the spring forward and moves into the third groove 164. When the rotating column 163 rotates over the slider 165, the slider 165 quickly moves backward and resets in the third groove 164 as the spring returns, so that two chambers are always formed in the second groove 162. The rotating column 163 rotates with the second groove 162, so that the heat dissipation liquid in the second groove 162 that absorbs the heat of the controller circuit board is squeezed into the heat sink 11 through the rotating column 163, and the cooled heat dissipation liquid in the heat sink 11 is simultaneously squeezed into the second groove 162, realizing the circulation of heat dissipation of the heat dissipation liquid and improving the cooling effect of the control circuit board.
