[0002] Servo drives generate a large amount of heat during operation. If this heat cannot be dissipated in a timely manner, it will negatively impact the servo drive's operational stability. Currently, servo drive cooling solutions vary depending on the power level of the servo drive: for low-power servo drives, natural cooling with a radiator is typically used. For high-power servo drives, natural cooling alone often cannot meet their heat dissipation requirements, so additional fans are often installed on the radiator for air cooling.

[0032] Combine Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a heat dissipation structure, which is applied to a driver. The driver includes a heat dissipation base 100 and a heat sink group 200. The heat sink group 200 is arranged on the heat dissipation base 100. The heat dissipation structure includes a fan body 10 and a fan bracket 20. The fan bracket 20 is arranged near one end of the heat sink group 200 and is snap-connected to the heat dissipation base 100. A mounting groove 21 is provided on the fan bracket 20, and the fan body 10 is detachably arranged in the mounting groove 21.
[0033] In this embodiment, the fan bracket 20 can be installed or removed without affecting the heat sink group 200 (that is, the fan bracket 20 is arranged on the side of the heat sink group 200 by a snap connection). A mounting slot 21 is provided on the fan bracket 20. One fan bracket 20 may be provided with only one mounting slot 21, or two mounting slots 21 or more mounting slots 21 may be provided side by side. The fan body 10 is detachably installed in the mounting slot 21. The fan body 10 can be quickly and easily removed from the fan bracket 20 when maintenance or replacement is required, which greatly reduces maintenance time and cost. When installing the fan body 10, the fan body 10 only needs to be inserted into the fan bracket 20 to be installed and fixed; when the fan body 10 has a malfunction and needs to be dismantled for repair or replacement, it can be easily removed by simply pulling the fan body 10 out of the fan bracket 20. The operation is simple and convenient, which effectively reduces the cost of installation hours for the entire machine and the cost of subsequent maintenance.
[0034] In one embodiment, a receiving groove 101 is provided on the heat dissipation base 100 , and an end of the receiving groove 101 away from the heat dissipation base 100 has a first opening 1011 , which is communicated with the receiving groove 101 , and the fan bracket 20 is inserted into the receiving groove 101 through the first opening 1011 .
[0035] In this embodiment, a receiving slot 101 is designed on the heat dissipation base 100. The receiving slot 101 is located adjacent to the heat sink assembly 200 and is used to accommodate the fan bracket 20. In other embodiments, multiple receiving slots 101 may be designed on the heat dissipation base 100 to accommodate multiple fan brackets 20. The first opening 1011 is directly connected to the receiving slot 101. The provision of the first opening 1011 allows the fan bracket 20 to slide quickly into the receiving slot 101. It also facilitates quick removal from the receiving slot 101 when the fan bracket needs to be repaired or replaced, thereby improving maintenance efficiency. When the fan bracket 20 is installed in the receiving slot 101 or removed from the receiving slot 101, it moves in a straight line.
[0036] Combine Figure 3 and Figure 4 As shown, in one embodiment, a hook 22 is provided at one end of the fan bracket 20 close to the heat dissipation base 100, and a hole 102 corresponding to the hook 22 is provided on the heat dissipation base 100; or a hole 102 is provided at one end of the fan bracket 20 close to the heat dissipation base 100, and a hook 22 corresponding to the hole 102 is provided on the heat dissipation base 100, and the hook 22 is engaged with the hole 102.
[0037] In this embodiment, a hook 22 is provided at one end of the fan bracket 20 close to the heat sink base 100, and a latch hole 102 is provided at a corresponding position of the heat sink base 100. The fan bracket 20 can be quickly and stably installed or removed by the mutual engagement of the hook 22 and the latch hole 102. Of course, the latch hole 102 can also be provided on the fan bracket 20, and the corresponding hook 22 can be provided on the heat sink base 100, so that the hook 22 and the latch hole 102 can also be engaged. The advantage of this latching method is that it provides a simple and efficient installation and disassembly method. When installing the fan bracket 20, the latching operation between the hook 22 and the latch hole 102 is simple and intuitive. The fan bracket 20 can be firmly installed by pressing the latch, which also facilitates subsequent maintenance work. If the fan body 10 needs to be replaced or repaired, the fan bracket 20 can be directly removed from the heat sink base 100.
[0038] Specifically, in this embodiment, one hook 22 and one corresponding hole 102 constitute a set of snap-fit groups, with a total of four snap-fit groups provided. Since the fan bracket 20 in this embodiment is rectangular, the four snap-fit groups are distributed on the four sides of the fan bracket 20. Of course, if the direct connection between the fan bracket 20 and the heat sink base 100 is not tight enough, more snap-fit groups can be provided as needed to strengthen the fixation.
[0039] In one embodiment, the fan bracket 20 is further provided with a fixing column 23 at one end close to the heat dissipation base 100, and a fixing hole 103 corresponding to the fixing column 23 is opened on the heat dissipation base 100; or the fan bracket is further provided with a fixing hole at one end close to the heat dissipation base, and a fixing column corresponding to the fixing hole is opened on the heat dissipation base, and the fixing column 23 is embedded in the fixing hole 103.
[0040] In this embodiment, a fixing column 23 is provided at one end of the fan bracket 20 close to the heat dissipation base 100 to further improve the stability of the structure. A fixing hole 103 corresponding to the fixing column 23 is opened at the corresponding position of the heat dissipation base 100. Of course, the fixing hole 103 can also be provided on the fan bracket 20, and the fixing column 23 can be correspondingly provided on the heat dissipation base 100, so that the connection between the fixing column 23 and the fixing hole 103 can also be achieved. When the fan bracket 20 is installed, the fixing column 23 is embedded in the fixing hole 103 to position the fan bracket 20 when installing it, so as to achieve quick installation. The number of fixing columns 23 can be set according to needs, as long as it does not interfere with the normal operation of other functions of the driver.
[0041] Combine Figure 5As shown, in one embodiment, the mounting slot 21 has a second opening 211 at one end away from the heat dissipation base 100, and the second opening 211 is connected to the mounting slot 21. The fan body 10 is inserted into the mounting slot 21 through the second opening 211. The fan bracket 20 has a first wire groove 24 at one end close to the heat dissipation base 100, and the heat dissipation base 100 is provided with a second wire groove 104 corresponding to the first wire groove 24.
[0042] In this embodiment, the fan body 10 is inserted into the mounting slot 21 through the second opening 211. When installing or removing the fan body 10 from the mounting slot 21, it moves in a straight line, namely, the direction of the second opening 211. This improves maintenance efficiency. The mounting slot 21 also prevents displacement of the fan body 10 due to vibration or external forces.
[0043] Furthermore, to optimize wire management, a first wire trough 24 is provided on the end of the fan bracket 20 near the heat sink 100, and a second wire trough 104 is provided on the heat sink 100 corresponding to the first wire trough 24. The design of the first and second wire troughs 24 and 104 allows the power cord to pass from the fan body 10 through the fan bracket 20 into the heat sink 100, and ultimately to the circuit board or other power interface. This not only protects the wires from damage but also enhances the overall layout simplicity.
[0044] In one embodiment, a protrusion 212 is provided on the inner wall of the mounting groove 21, and a groove 11 corresponding to the protrusion 212 is provided on the outer wall of the fan body 10, or a groove 11 is provided on the inner wall of the mounting groove 21, and a protrusion 212 corresponding to the groove 11 is provided on the outer wall of the fan body 10.
[0045] In this embodiment, a protrusion 212 is provided on the inner wall of the mounting slot 21 of the fan bracket 20, and a groove 11 corresponding to the protrusion 212 is correspondingly provided on the outer wall of the fan body 10. When the fan body 10 is installed in the mounting slot 21, the protrusion 212 is embedded in the groove 11, thereby completing positioning and fixing. Alternatively, in another design, the inner wall of the mounting slot 21 is provided with a groove 11, and the outer wall of the fan body 10 is provided with a protrusion 212 corresponding to the groove 11, which can also complete positioning and fixing. In addition, the mutual cooperation between the protrusion 212 and the groove 11 can reduce the displacement of the fan body 10 caused by vibration or other external forces.
[0046] Specifically, the protrusion 212 in this embodiment is set as a circular protrusion, and the groove 11 is correspondingly set as a circular groove, and can also be set to other shapes, such as a rectangle. The fan body 10 has a front and a back side, and a groove 11 is set at the four end corners of the front and back sides respectively (a total of eight grooves 11); a corresponding protrusion 212 is set in the mounting groove 21 of the fan bracket 20, and there are four protrusions 212 here, namely, the grooves 11 at the two end corners corresponding to the front of the fan body 10, and the grooves 11 at the two end corners corresponding to the back of the fan body 10. When the grooves 11 of the fan body 10 are adapted to the protrusions 212 of the fan bracket 20, only four grooves 11 need to be used, and the four unused grooves 11 can remain idle. This makes it convenient for the fan body 10 to be quickly installed on the fan bracket 20 without having to spend time looking for the corresponding grooves 11 on the fan body 10.
[0047] In one embodiment, a first elastic member 213 is disposed on the inner wall of the installation slot 21 and extends toward the inside of the installation slot 21 . The first elastic member 213 abuts against the outer wall of the fan body 10 .
[0048] In this embodiment, the first elastic member 213 can exert a certain amount of pressure on the fan body 10, thereby ensuring a relatively stable position of the fan body 10 during operation. Due to the natural elastic force of the first elastic member 213, the fan body 10 can be easily pushed into or pulled out of the mounting slot 21, achieving quick installation and removal.
[0049] In one embodiment, the first elastic member 213 includes a connecting end and a movable end. The connecting end is connected to the inner wall of the installation slot 21 , and the movable end is movably arranged and extends toward the inside of the installation slot 21 .
[0050] In this embodiment, the end of the first elastic member 213 away from the heat sink base 100 serves as the connection end, and the end of the first elastic member 213 closer to the heat sink base 100 serves as the movable end. The movable end can swing, such as back and forth or left and right, in response to the compression of the fan body 10. The movable end extends toward the interior of the mounting slot 21. The first elastic member 213 can provide elastic force when the fan body 10 is installed or removed, thereby securing or releasing the fan body 10. The movable arrangement of the first elastic member 213 enables the first elastic member 213 to provide appropriate displacement to adjust the space when subjected to external forces.
[0051] In summary, the present invention eliminates the need for a fan frame in a conventional fixing structure and directly fixes the fan body 10 , thereby improving the efficiency of disassembling the fan body 10 and reducing the space occupied by components of the conventional fan fixing structure.
[0052] Combine Figure 6 and Figure 7As shown, an embodiment of the present invention also provides a driver, which includes a shell 300, a heat dissipation base 100, a heat sink group 200 and the heat dissipation structure as described above, the heat dissipation base 100 is arranged on the shell 300, the heat dissipation structure and the heat sink group 200 are both arranged on the heat dissipation base 100, and the heat dissipation structure is located at one end of the heat sink group 200.
[0053] In this embodiment, the heat dissipation structure is located to the side of the heat sink assembly 200. This layout enables the heat dissipation structure to effectively dissipate heat from the heat sink assembly 200. By integrating the heat dissipation structure and the heat sink assembly 200 on the heat dissipation base 100, the overall structure of the driver is simplified, making assembly and maintenance more convenient.
[0054] In one embodiment, a second elastic member 301 is disposed on the inner wall of the housing 300 and abuts against the fan body 10 .
[0055] In this embodiment, a second elastic member 301 is provided on the inner wall of the housing 300. The second elastic member 301 abuts against the fan body 10 to ensure the stability of the fan body during operation. When the fan body 10 is installed in the driver, the second elastic member 301 contacts the outer wall of the fan body 10 with slight pressure. This reduces minor vibrations or displacements caused by the operation of the fan body 10 without causing excessive mechanical stress on the fan body 10.
[0056] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention.
