DETAILED DESCRIPTION

[0019] To make the objectives, technical solutions, and advantages of the present invention more apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that any directional terms such as "up," "down," "left," "right," "front," "back," "inside," and "outside" that appear or will appear herein are based solely on the accompanying drawings and are not intended to limit the present invention.

[0020] Example 1, a high-protection servo motor controller, such as Figures 1-6 As shown, it includes a base plate 1 and a cover 2; the cover 2 is bolted to the base plate 1, and the base plate 1 can be set to a plastic material or an alloy material; it also includes a button 3, an electrical component 4, a processor 5, a cover 6, a heat sink 7, a heat conducting plate 8, a heat conducting block 9 and a conveying assembly; the button 3 is installed on the cover 2; the electrical component 4 is installed on the base plate 1, and the electrical component 4 is located inside the cover 2, and the electrical component 4 is electrically connected to the button 3; the electrical component 4 is connected to the processor 5 ; A cover shell 2 6 is slidably connected to the cover shell 2; a number of heat sinks 7 are fixedly connected to the inner side of the cover shell 2 6; the heat sink 7 is arc-shaped and elastic; a heat conducting plate 8 is slidably connected to the inner side of the cover shell 2 6, and the heat conducting plate 8 is fixedly connected to the heat sink 7, and the heat conducting plate 8 is transferred to the heat sink 7 through the heat conducting plate 8; a heat conducting block 9 is welded to the lower side of the heat conducting plate 8, and the heat conducting block 9 is plugged into the cover shell 2, and the heat conducting block 9 is connected to the processor 5, and the heat conducting block 9 is set to be made of metal; a conveying component is connected to the cover shell 2.

[0021] The conveying assembly includes a fan 201 and a guide plate 202; three fans 201 are bolted to the cover 1 2, and the fans 201 are electrically connected to the electrical component 4; a guide plate 202 is fixed between the bottom plate 1 and the cover 1 2, and the guide plate 202 is arranged at an angle; a cavity 1 91 is formed between the bottom plate 1, the cover 1 2, the cover 2 6 and the guide plate 202; a cavity 2 92 is formed between the cover 2 6, the heat conducting plate 8 and each adjacent two heat sinks 1 7, and the cavity 2 92 is connected to the cavity 1 91; located A cavity three 93 is formed between the heat sink 1 7, the cover 2 6 and the heat conducting plate 8 at one end, and the cavity three 93 is communicated with the cavity one 91; a cavity four 94 is formed between the heat sink 1 7, the cover 2 6 and the heat conducting plate 8 at the other end, and the cavity four 94 is communicated with the cavity one 91. When the fan 201 is started, the fan 201 draws out the air in the cavity one 91, so that the air in the cavity two 92, the cavity three 93 and the cavity four 94 flows into the cavity one 91, thereby promoting the outside air to flow into each cavity and form a circulating airflow.

[0022] It also includes a filter 203; three filters 203 are fixed to the cover 2, and the filter 203 is located on the side of the corresponding fan 201. The filter 203 can intercept impurities in the air.

[0023] The second cover 6 is also provided with a second filter 204 ; the second filter 204 is fixedly connected to the cover 6 , and the impurities in the air are intercepted by the second filter 204 .

[0024] It also includes a heat sink 205; five heat sinks 205 are welded on the heat sink 1 7 at both ends, wherein a portion of the heat sink 205 is located in the cavity 3 93, and another portion of the heat sink 205 is located in the cavity 4 94.

[0025] It also includes a shock-absorbing component, which includes friction strips 206 and friction plates 207; two friction strips 206 are fixedly connected to the heat conducting plate 8; two friction plates 207 are fixedly connected to the cover 2 6, and the friction plates 207 are slidably connected to the corresponding friction strips 206.

[0026] First, manually press the button 3 to control the servo motor through the electrical component 4 and the processor 5 to realize the basic function of controlling the servo motor; the processor 5 generates heat during operation, and the heat is transferred to the heat conducting plate 8 through the heat conducting block 9, and then conducted to all the heat sinks 7 through the heat conducting plate 8, and the fan 201 is started by the electrical component 4 and the processor 5. The fan 201 draws out the air in the cavity 1 91, so that the air in the cavity 2 92, the cavity 3 93 and the cavity 4 94 flows into the cavity 1 91, prompting the outside air to flow into each cavity and form a circulating airflow. In this process, the air is guided by the guide plate 202, so that the air flows from the cavity 2 92, the cavity 3 93 and the cavity 4 94 into the cavity 1 91 more smoothly, and the heat on the heat sink 7 is taken out by the flowing air, thereby realizing Heat dissipation effect on processor 5; when falling rocks fall onto cover 2 6, a downward impact force is generated, which drives cover 2 6 to move downward. At this time, the heat conducting plate 8 supported on cover 1 2 is in a stationary state, so that cover 2 6 moves downward relative to the heat conducting plate 8, and then squeezes heat sink 1 7. Since heat sink 1 7 is set in an arc shape, heat sink 1 7 undergoes adaptive elastic deformation to reduce the impact force and realize buffering function. Then heat sink 1 7 rebounds and drives cover 2 6 to move upward back to its original position. When in use, the processor 5 is cooled by heat sink 1 7. The arc-shaped heat sink 1 7 can also be used to buffer falling rocks, thereby protecting the controller. At the same time, after setting heat sink 1 7 to an arc shape, the heat exchange area between heat sink 1 7 and airflow can be increased, which is beneficial to improving the heat dissipation effect.

[0027] After the heat sink 1 7 is set to an arc shape, a cavity 3 93 and a cavity 4 94 will be formed at the inner front and inner rear of the cover 2 6, and the cavity 3 93 and the cavity 4 94 are much larger than the cavity 2 92, so that the heat exchange efficiency of the air flowing through the cavity 3 93 and the cavity 4 94 is low, resulting in the heat dissipation efficiency of this area not being fully utilized. Therefore, a heat sink 205 is set in the cavity 3 93 and the cavity 4 94. During the heat dissipation process, the heat sink 1 7 located at the front and rear ends will transfer heat to the heat sink 205. When the air flows through the cavity 3 93 and the cavity 4 94, it fully contacts the heat sink 205 and exchanges heat with it, so that the heat dissipation function of this part of the air can be fully utilized. By setting the heat sink 205 in the cavity 3 93 and the cavity 4 94, the heat dissipation function of the air in the cavity 3 93 and the cavity 4 94 can be fully utilized, which is beneficial to improving the heat dissipation effect of the processor 5.

[0028] After the rockfall hits the cover 2 6, the impact force is buffered by the elastically deformed heat sink 1 7. However, vibration is generated during the reciprocating rebound process of the heat sink 1 7. The vibration is transmitted to the electrical component 4 and the processor 5, which will cause the electrical connection points therein to become loose, thereby increasing the failure rate. Therefore, a shock-absorbing component is provided on the cover 2 6. When the cover 2 6 moves downward and resets upward, the cover 2 6 drives the friction plate 207 to move in the vertical direction. The friction plate 207 slides on the friction strip 206 and generates friction heat energy, thereby converting the mechanical vibration energy into heat energy through friction damping to achieve a shock-absorbing effect. At the same time, the friction strip 206 and the friction plate 207 are located close to the cavity 3 93 and the cavity 4 94, that is, the additional friction generated Frictional heat energy is located in cavity three 93 and cavity four 94, and cavity three 93 and cavity four 94 are set to be larger than cavity two 92, so that the air flow in cavity three 93 and cavity four 94 is greater than the air flow in cavity two 92, which can just meet the greater heat dissipation demand of cavity three 93 and cavity four 94. When in use, the friction strip 206 and the friction plate 207 cooperate to convert mechanical vibration energy into heat energy through friction damping to achieve a shock absorption effect, which is beneficial to improving the operating stability of the controller. At the same time, the location where the friction strip 206 and the friction plate 207 generate frictional heat is located in cavity three 93 and cavity four 94, and the air flow in cavity three 93 and cavity four 94 is greater than the air flow in cavity two 92, which can just meet the greater heat dissipation demand.

[0029] Example 2, based on Example 1, Figure 7 and Figure 8 As shown, it also includes a fixing component, which includes a fixing bar 208, a connecting block 209, a fixing block 2010 and a screw 2011; two fixing bars 208 are welded on the cover 2 6; four connecting blocks 209 are welded on the cover 1 2, and the connecting blocks 209 are set to plastic material; each connecting block 209 is slidably connected to a fixing block 2010; each fixing block 2010 is screwed to a screw 2011, and the screw 2011 is screwed to the corresponding connecting block 209.

[0030] A spring 2012 is also included; a spring 2012 is fixedly connected between each connecting block 209 and the corresponding fixing block 2010, and the corresponding fixing block 2010 is ejected by the spring 2012.

[0031] The electrical component 4 is provided with a temperature sensor for monitoring the temperature of the processor 5 .

[0032] A gallium-indium-tin alloy coating is provided between the processor 5 and the heat-conducting block 9 to enhance the heat transfer effect between the processor 5 and the heat-conducting block 9 .

[0033] During installation, the gallium indium tin alloy coating is manually applied to the side of the processor 5, and then the cover 2 6 and the parts thereon are inserted into the upper side of the cover 1 2, and the heat conducting block 9 is fitted with the processor 5. Then, the cover 2 6 is manually pressed downward, and the cover 2 6 drives the heat sink 1 7, the heat conducting plate 8 and the heat conducting block 9 to move downward, pressing the heat conducting block 9 tightly against the processor 5 until the fixing bar 208 moves below the corner of the fixing block 2010. At this time, the heat sink 1 7 is deformed by the extrusion force, and then the screw 2011 is manually tightened, so that the screw 2011 pushes the fixing block 2010 toward the cover 1 2 and compresses the spring 2012. Figure 7 As shown, the corner of the fixing block 2010 is moved to above the fixing bar 208, and the upper side of the fixing bar 208 is limited. After the extrusion is stopped, the elastic restoring force of the heat sink 1 7 pushes the cover 2 6 to move upward, and the cover 2 6 drives the fixing bar 208 to move upward, so that the fixing bar 208 is against the corner of the fixing block 2010, and the installation operation is completed. At this time, the heat sink 1 7 is still in a bent state, so that the heat sink 1 7 presses the heat conductive block 9 on the processor 5 through elastic force. Compared with conventional rigid fixation, elastic fixation can offset thermal expansion displacement (such as thermal expansion of the processor 5 and the heat conductive block 9), maintain constant pressure, avoid loosening of the contact surface or sudden increase in pressure due to thermal expansion and contraction, and ensure that the processor 5 and The stable connection of the heat-conducting block 9 ensures the heat dissipation effect. When in use, the fixing bar 208 and the fixing block 2010 cooperate to make the heat sink 7 press the heat-conducting block 9 onto the processor 5 through elastic force. Compared with the conventional rigid fixation, the elastic fixation can offset the thermal expansion displacement, maintain a constant pressure, and avoid loosening of the contact surface or a sharp increase in pressure due to thermal expansion and contraction, thereby ensuring a stable connection between the processor 5 and the heat-conducting block 9, thereby ensuring the heat dissipation effect. At the same time, the movement distance of the cover 2 6 can be limited by the connecting block 209 to avoid excessive squeezing of the cover 2 6 on the heat sink 7. In addition, the fixing bar 208 can also block falling rocks to prevent them from falling to the position of the button 3, further improving the protection effect.
