Description

Technical Field

[0001] The utility model relates to the technical field of motor drivers, in particular to a motor driver with a heat dissipation structure. Background Art

[0002] A motor driver is a device used to control the operation of a motor. It converts input electrical signals into current and voltage suitable for the motor's operation, enabling speed regulation, forward and reverse rotation control, and start and stop operations. The motor driver operates by receiving external control signals, such as speed and direction reference signals, through a control circuit. Based on these signals, it generates corresponding control instructions. These control instructions are then sent to the driver circuit, which amplifies the control signals and drives switching devices in the power circuit, such as transistors and IGBTs. The power circuit converts the input power supply voltage into a voltage and current suitable for the motor's operation, thereby driving the motor's rotation.

[0003] Motor drivers generate significant heat during operation, but existing motor drivers lack heat dissipation structures to manage this heat. High temperatures can severely damage the electronic components within the motor driver. For example, semiconductor devices can experience performance degradation, increased leakage, or even burn out when exposed to high temperatures. Effective heat dissipation measures can keep the driver's temperature within a safe range and extend the life of the electronic components. When the motor driver's temperature is too high, the resistance of the internal electronic components increases, leading to increased energy loss. Utility Model Content

[0029] Example 1, combined with Figures 1 to 3 A motor driver with a heat dissipation structure includes a motor driver body 3, a heat dissipation mechanism 1 is arranged on the top of the motor driver body 3, and a fixing mechanism 2 is arranged on the front side of the heat dissipation mechanism 1.

[0030] The heat dissipation mechanism 1 includes a heat dissipation component 11, a flip component 12, an installation component 13 and a fixing component 14.

[0031] The heat dissipation component 11 includes a top cover 1101, which is snapped onto the top of the motor driver body 3. An exhaust fan 1102 is fixedly connected to the top of the top cover 1101. Air inlet holes 1103 are provided at the bottom of the left and right sides of the top cover 1101.

[0032] Furthermore: the staff only needs to start the exhaust fan 1102 to draw the air in the top cover 1101 outward, so that the external air continuously flows into the top cover 1101 through the air inlet 1103 and contacts the top components of the motor driver body 3 for heat exchange, thereby completing the cooling treatment of the top components of the motor driver body 3, so that the components of the motor driver body 3 will not malfunction or be damaged due to overheating when in use, thereby increasing the service life of the motor driver body 3 and improving the stability of the motor driver body 3 when in use.

[0033] Example 2, see Figure 1 、 Figure 2 、 Figure 4 and Figure 5 , and on the basis of Example 1, it is further obtained that the fixing mechanism 2 includes a splicing component 21, a reset component 22 and a positioning component 23, the splicing component 21 is arranged on the front side of the heat dissipation component 11, the reset component 22 is arranged on the left and right sides of the splicing component 21, and the positioning component 23 is arranged on the rear side of the reset component 22.

[0034] The splicing component 21 includes a positioning rod 2101, which is fixedly connected to the front side of the motor driver body 3, and the positioning rod 2101 is clamped in the front side of the top cover 1101. The outer ring of the positioning rod 2101 is sleeved with a sleeve 2102, and the rear side of the sleeve 2102 fits the front side of the top cover 1101. The front side of the sleeve 2102 is fixedly connected with a handle 2103. The reset component 22 includes a fixing frame 2201, which is fixedly connected to the front side of the top cover 1101 and is located on the left and right sides of the sleeve 2102. The fixing frame 2201 is fixedly connected to a fixing box 2202. A slide 2203 is slidably connected inside the fixed box 2202, a compression spring 2204 is fixedly connected to the outside of the slide 2203, a pull rod 2205 is fixedly connected to the front side of the slide 2203, and the pull rod 2205 is slidably connected to the front side of the fixed box 2202. The positioning assembly 23 includes a connecting slide 2301, the connecting slide 2301 is fixedly connected to the rear side of the slide 2203, the connecting slide 2301 is slidably connected to the rear side of the fixed box 2202, and a positioning frame 2302 is fixedly connected to the inside of the connecting slide 2301. The positioning frame 2302 is sleeved on the front left and right sides of the sleeve 2102.

[0035] Furthermore: the positioning frames 2302 on the left and right sides are sleeved on the outside of the sleeve 2102 and the positioning of the top cover 1101 is completed through the positioning rod 2101 connected to the sleeve 2102, so that the top cover 1101 will not shake when the motor driver body 3 is in use, ensuring the contact and sealing between the top cover 1101 and the top of the motor driver body 3. At the same time, the staff only needs to pull the pull rods 2205 on the left and right sides outward to drive the positioning frames 2302 on the left and right sides to move outward. After that, the staff can flip the top cover 1101 upward to complete the opening and closing of the top cover 1101, so that the setting of the top cover 1101 will not hinder the maintenance of the motor driver body 3 and is convenient for the staff to use.

[0036] In actual operation, when this device is used, the staff only needs to start the exhaust fan 1102. The exhaust fan 1102 starts to draw the air in the top cover 1101 upward and discharge it. At this time, negative pressure is formed in the top cover 1101, drawing the external air into the internal space of the top cover 1101 through the air inlet 1103. The air entering the top cover 1101 exchanges heat with the components on the top of the motor driver body 3, completing the cooling of the components. After that, the heated air continues to be discharged upward, and this reciprocating process completes the cooling and heat dissipation treatment of the motor driver body 3.

[0037] When it is necessary to open and close the top cover 1101, the staff first pulls the pull rods 2205 on the left and right sides to move outward. The pull rods 2205 move outward and drive the connecting slide rods 2301 and the positioning frames 2302 to move outward through the slide cylinder 2203. The positioning frames 2302 on the left and right sides move outward to release the positioning of the sleeve plate 2102. Then the staff pulls the handle 2103 forward, and the handle 2103 drives the sleeve plate 2102 forward. After that, the staff can flip the top cover 1101 upward to complete the opening and closing of the top cover 1101. After that, the staff can inspect and maintain the components on the top of the motor driver body 3.

[0038] When the top cover 1101 needs to be disassembled, the staff first rotates the bolt 1401, and the bolt 1401 rotates and moves backward on the inner ring of the fixed screw barrel 1402. The bolt 1401 moves backward and disengages from the connection with the fixed screw barrel 1402, and then continues to move the bolt 1401 backward to disengage the bolt 1401 from the sleeve 1304 and the clamping rod 1303. After that, the staff can move the top cover 1101 upward. The upward movement of the top cover 1101 drives the clamping rod 1303 to move upward, and the clamping rod 1303 disengages from the connection with the sleeve 1304 and the frame plate 1301. At this time, the disassembly of the top cover 1101 is completed.

[0039] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising a..." does not exclude the presence of additional identical elements in the process, method, article, or device comprising the element.
