[0035] The connecting rod assembly 20 is installed on the base 10 and is located at the driver placement position. The connecting rod assembly 20 includes two first connecting rods 21, two second connecting rods 22, a central shaft 23, a support rod 24 and a support plate 25, wherein one end of one of the first connecting rods 21 is rotatably connected to one end of one of the second connecting rods 22, one end of the other first connecting rod 21 is rotatably connected to one end of the other second connecting rod 22, and the other ends of the two first connecting rods 21 are rotatably connected to each other, the central shaft 23 is penetrated at the connection of the two first connecting rods 21, one end of the support rod 24 is connected to the central shaft 23, the support plate 25 is fixedly connected to the other end of the support rod 24, and the side of the support plate 25 facing away from the support rod 24 abuts against the bottom of the servo driver 50;

[0036] The cover plate assembly 60 includes two upper cover plates 61 and a linkage assembly 62.

The linkage assembly 62 is connected to the support plate 25. The linkage assembly 62 is spaced apart from the servo driver 50. The two upper cover plates 61 are provided with exhaust holes 611. The cover plate assembly 60, the first side plate 11, the second side plate 12, and the two limit plates 13 enclose an installation cavity, and the installation cavity is used for installing the servo driver 50.

[0037] The fixing assembly 40 includes two clamping members 41 and two supports 42. The two clamping members 41 are arranged on two opposite sides of the base 10. The clamping members 41 are used to clamp the servo driver 50. Each clamping member 41 includes a clamping plate 411 and a connecting rod 414. The clamping plate 411 is connected to one end of the connecting rod 414. The other end of the connecting rod 414 is rotatably connected to an end of a second connecting rod 22 away from the first connecting rod 21. One of the supports 42 is installed on a side of the first side plate 11 away from the second side plate 12, and the other support 42 is installed on a side of the second side plate 12 away from the first side plate 11. One of the connecting rods 414 is movably connected to one of the supports 42, and the other connecting rod 414 is movably connected to the other support 42; and

[0038] The exhaust assembly 70 has mounting holes 131 formed on the two limiting plates 13 , and the exhaust assembly 70 is mounted in the mounting holes 131 .

[0039] Among them, two clamping members 41 are provided on the base 10 for installing and fixing the servo driver 50. The servo driver 50 is arranged in the first side plate 11 and the second side plate 12 to complete the positioning. At the same time, the servo driver 50 presses the support plate 25, and the support plate 25 is connected to the central axis 23 through the support rod 24. At this time, the servo driver 50 is pressed downward, and the support plate 25 moves downward, driving the central axis 23 to move. The central axis 23 connects the two first connecting rods 21 together, thereby driving the two first connecting rods 21 to rotate. When the two first connecting rods 21 approach parallelism, the two second connecting rods 22 will be pushed outward on both sides of the base 10, so that the connecting rod 4 connected to the second connecting rod 22 14 will gradually approach one side of the servo driver 50, and the clamping plates 411 on both sides will gradually clamp; when the two first connecting rods 21 gradually change from a parallel state to a certain angle, the two second connecting rods 22 gradually shrink inwards towards the direction of the first connecting rod 21, and the connecting rods 414 on both sides gradually open outwards; the two limiting plates 13 are arranged oppositely, the first side plate 11 and the second side plate 12 are arranged oppositely, and any limiting plate 13 is adjacent to the first side plate 11 and the second side plate 12, and the four are enclosed to form a driver placement position, that is, the first side plate 11 and the second side plate 12 are arranged oppositely in the width direction of the driver placement position, and the two limiting plates 13 are arranged oppositely in the length direction of the driver placement position. In this way, the two limiting plates 13 are respectively and individually abutted against the outer surface of the servo driver 50, thereby limiting the two sides of the servo drive, and at the same time, the first side plate 11 and the second side plate 12 limit the servo driver 50 separately.

[0040] The technical solution of the present invention is to set a first side plate 11, a second side plate 12 and two limit plates 13 around the driver placement position, and set a cover plate assembly 60 at one end away from the driver placement position. After the servo driver 50 is placed on the support plate 25, the cover plate assembly 60 is pressed down to cover the cover plate assembly 60 in a linkage manner, so that the cover plate assembly 60, the first side plate 11, the second side plate 12, and the two limit plates 13 are enclosed to form an installation cavity. An exhaust assembly 70 is provided on the limit plate 13 to discharge air from the installation hole 131 into the installation cavity, and then the air is discharged from the exhaust hole 611 of the upper cover plate 61 after flowing in the installation cavity. In this way, the servo driver 50 is installed in the installation cavity to reduce the direct contact between the servo driver 50 and the air. At the same time, the exhaust assembly 70 is set to allow the air inside the installation cavity to circulate continuously, so that the moisture in the air can be discharged from the installation cavity, so that the environment inside the installation cavity is gradually dried, and the possibility of moisture condensing into water droplets is reduced, thereby reducing the possibility of water droplets entering the interface of the servo driver 50, so as to reduce the possibility of damage to the servo driver 50.

[0041] In one embodiment, the exhaust assembly 70 includes two exhaust fans 71 , and each of the mounting holes 131 of the two limiting plates 13 is provided with an exhaust fan 71 .

[0042] Specifically, air flows into the exhaust fan 71 from the mounting hole 131, and the exhaust fan 71 discharges the air into the mounting cavity for circulation, and then discharges it from the exhaust hole 611 of the upper cover 61. Compared with the passive air intake scheme, that is, air enters the mounting cavity from the mounting hole 131 and then discharges it from the exhaust hole 611 of the upper cover 61, the exhaust fan 71 is provided for active air intake, so that the flow rate of air in the mounting cavity is increased, which can speed up ventilation and better discharge moisture in the air. In some other embodiments, both exhaust fans 71 are installed on the side of the upper cover 61 facing the servo driver 50.

[0043] In one embodiment, the moisture-proof device for the servo driver 50 interface also includes a humidity sensor 80 and an electronic control component. The humidity sensor 80 is installed on the side of any limit plate 13 facing the servo driver 50, and the electronic control component is installed on the side of the first side plate 11 away from the servo driver 50 or the side of the second side plate 12 away from the servo driver 50. The humidity sensor 80 is electrically connected to the electronic control component, and the electronic control component is electrically connected to the exhaust fan 71.

[0044] Specifically, the servo driver 50 needs to work in a dry environment, so it is necessary to ensure that the humidity of the installation cavity is not too high to affect the operation of the servo driver 50. A humidity sensor 80 is provided in the installation cavity. The humidity sensor 80 can be installed on the first side wall or the second side wall. The humidity sensor 80 can monitor the humidity in the installation cavity in real time. When the humidity exceeds the ideal working state, it will send a signal to the electronic control component, and the electronic control component controls the speed of the exhaust fan 71. The speed of the exhaust fan 71 is low under normal humidity conditions; when the humidity is too high, the speed of the exhaust fan 71 will increase, so that the air flow rate will increase. When the humidity in the installation cavity returns to the normal value, the fan is controlled to return to low speed operation; such a setting can ensure real-time supervision of the humidity in the installation cavity, and at the same time can adjust the wind speed of the exhaust fan 71 according to different humidity, so that the fan does not need to work at high speed for a long time, which can save electricity costs; the electronic control component is arranged outside the cavity, which is convenient for maintenance when problems occur. In some other embodiments, the electronic control component is installed on the side of the first side plate 11 facing the servo driver 50 or the side of the second side plate 12 facing the servo driver 50.

[0045] In one embodiment, the exhaust assembly 70 includes a desiccant plate 72 , on which a plurality of air inlet holes 721 are provided. The desiccant plate 72 is connected to the exhaust fan 71 , and one air inlet end of the exhaust fan 71 is connected to the plurality of air inlet holes 721 .

[0046] Specifically, the moisture absorption plate 72 is arranged at one end of the exhaust fan 71 for air inlet, and the multiple air inlet holes 721 on the moisture absorption plate 72 are connected to one end of the exhaust fan 71 for air inlet. When air flows into the mounting hole 131, the air passes through the moisture absorption plate 72, and the moisture absorption plate 72 can absorb part of the moisture in the air. This arrangement makes the air entering the mounting cavity relatively dry, which can reduce the possibility of moisture entering the servo driver 50. In some other embodiments, a sponge block is provided, and the sponge block is arranged at one end of the exhaust fan 71 for air inlet.

[0047] In one embodiment, the moisture absorbing plate 72 is made of diatom mud, water-absorbing epoxy resin or silicone foam.

[0048] Specifically, the hygroscopic plate 72 made of diatom mud, water-absorbing epoxy resin or silica gel foam has the advantage of good water absorption. In this way, when air passes through the hygroscopic plate 72, it can better absorb moisture in the air. In some other embodiments, the hygroscopic plate 72 is made of glass fiber.

[0049] In one embodiment, there are multiple exhaust holes 611 , and the multiple exhaust holes 611 are arranged at intervals on the upper cover plate 61 .

[0050] Specifically, the more exhaust holes 611 there are, the larger the volume of air that can be discharged at a time, and the spacing allows the air to be discharged from different angles. In this way, with each additional exhaust hole 611, the total area of ​​the holes for air discharge increases, so that the volume of air that can be discharged each time is larger. At the same time, the multiple exhaust holes 611 are spaced apart from each other, so that the air is discharged from each exhaust hole 611 in irregular motion, which can improve the air exchange efficiency in the installation cavity and ensure that moisture will not accumulate in the installation cavity. In some other embodiments, multiple exhaust holes 611 are arranged adjacent to each other in pairs on the upper cover plate 61.

[0051] In one embodiment, a plurality of exhaust holes 611 constitute a plurality of exhaust rings, and the plurality of exhaust rings are nested in sequence from the inside to the outside, and a line connecting the center points of the plurality of exhaust holes 611 on each exhaust ring forms a ring, and an interval between any two adjacent exhaust holes 611 on the same exhaust ring gradually increases from the inside to the outside, and the exhaust holes 611 on the same exhaust ring have the same size.

[0052] Specifically, the multiple exhaust holes 611 are arranged in a ring shape to form multiple exhaust rings. The closer the multiple exhaust holes 611 are to the middle area, the denser they are arranged, and the farther the multiple exhaust holes 611 are from the middle area, the sparser they are arranged. In this way, the multiple exhaust holes 611 in the middle area are more concentrated, so that the air convergence speed in the middle area is greater than the air convergence speed in other areas. In this way, the air flow rate in the middle area is greater, so the ventilation efficiency in the middle area is higher. In some other embodiments, the multiple exhaust holes 611 are arranged in a rectangular array.

[0053] In one embodiment, the linkage assembly 62 includes at least two first hinges 621 and two linkage rods 622, any one of the first hinges 621 is installed on one of the upper cover plates 61, and the other first hinge 621 is installed on the other upper cover plate 61, each linkage rod 622 is rotatably connected to a first hinge 621, and the other end is connected to the support plate 25, the cover plate assembly 60 also includes at least two second hinges 601, one second hinge 601 is installed on the first side plate 11, and the other second hinge 601 is installed on the second side plate 12, and each upper cover plate 61 is connected to a second hinge 601.

[0054] Specifically, the first hinge 621 is fixed to the side of the upper cover 61 facing the servo drive 50, the linkage rod 622 can rotate on the first hinge 621, the other end of the linkage rod 622 is fixed to the support plate 25, and one side of the upper cover 61 is rotatably connected to the second hinge 601. When the support plate 25 moves downward, the linkage rod 622 can pull the first hinge 621, thereby driving the upper cover 61 to flip and cover the top of the servo drive 50. This arrangement has a simple structure, and when the servo drive 50 is placed on the support plate 25, the support plate 25 moves downward, and the upper cover 61 automatically closes, which is convenient and simple to operate. In some other embodiments, the cover assembly 60 also includes two second hinges 601, one second hinge 601 is installed on the first side plate 11, and the other second hinge 601 is installed on the second side plate 12, and each upper cover 61 is connected to a second hinge 601.

[0055] In one embodiment, there are four first hinges 621 and four connecting rods 622, and each upper cover plate 61 is installed with two first hinges 621. The two first hinges 621 are spaced apart on a side of the upper cover plate 61 facing the servo drive 50, and the two first hinges 621 are spaced apart from each other in the length direction of the upper cover plate 61.

[0056] Specifically, two first hinges 621 are provided on one upper cover plate 61, and the two first hinges 621 are spaced apart from each other. In this way, when the support plate 25 moves downward to drive the upper cover plate 61 to close, the two linkage rods 622 simultaneously pull the upper cover plate 61 to flip and close, and the two linkage rods 622 can evenly distribute the pulling force, and will not apply all the force to one first hinge 621, so that the connection between the linkage rod 622 and the first hinge 621 is more stable, and the service life of the linkage assembly 62 is increased. In some other embodiments, there are two first hinges 621, two linkage rods 622, and each upper cover plate 61 is equipped with a first hinge 621.

[0057] In one embodiment, the base 10 also includes a second elastic member 14 and a mounting plate 19 , the mounting plate 19 is connected to the second elastic member 14 , the mounting plate 19 is arranged on the opposite side of any one of the limiting plates 13 , and the second elastic member 14 is connected to the limiting plate 13 close to the mounting plate 19 .

[0058] Specifically, one of the limit plates 13 is connected to the second elastic member 14, and the limit plate 13 can move in the extension direction of the second elastic member 14, so that when the servo driver 50 is installed, the second elastic member 14 connected to the limit plate 13 can be compressed first, so that the limit plate 13 moves a certain distance, and when the servo driver 50 is placed on the support plate 25, the compressed second elastic member 14 is released, and the limit plate 13 rebounds and abuts against one side of the servo driver 50. In this way, the second elastic member 14 can be compressed to different lengths, so that the limit plate 13 moves different distances, so as to adapt to the installation of servo drivers 50 of different lengths or widths, thereby enhancing the adaptability of the installation structure of the servo driver 50. In some other embodiments, two limit plates 13 are fixed to the base 10.

[0059] In one embodiment, the base 10 is provided with a reset hole 15, the opening of the reset hole 15 faces the connecting rod assembly 20, and the connecting rod assembly 20 further includes a reset structure 30, the reset structure 30 includes a first elastic member 31 and a reset block 32, the first elastic member 31 and the reset block 32 are arranged in the reset hole 15, the first elastic member 31 is sleeved on the reset block 32, one end of the first elastic member 31 abuts against the bottom of the reset hole 15, and the reset block 32 is connected to the central shaft 23;

[0060] A first pin hole 16 is also provided on one side of the base 10, and the first pin hole 16 is connected to the reset hole 15. The reset block 32 is provided with a second pin hole 321, and the second pin hole 321 faces the first pin hole 16. The fixing assembly 40 also includes a first pin 43, and the first pin 43 is inserted into the second pin hole 321 through the first pin hole 16.

[0061] Specifically, the reset block 32 is connected to the central axis 23. When the servo drive 50 is placed on the support plate 25 during the installation process, the support plate 25 moves downward to press the central axis 23 downward. At this time, the reset block 32 gradually moves to the connection between the reset hole 15 and the first pin hole 16. The first latch 43 is inserted into the second pin hole 321 on the reset block 32. The first latch 43 can limit the up and down movement of the reset block 32, thereby limiting the up and down movement of the servo drive 50. The first elastic member 31 is in a compressed state; when the disassembly process is carried out, the first latch 43 is pulled out of the second pin hole 321, and the first elastic member 31 in the compressed state rebounds, so that the reset block 32 moves upward, and the support plate 25 moves upward with the movement of the reset block 32 to eject the servo drive 50. In this way, when the servo drive 50 is disassembled, the support plate 25 will automatically rebound, thereby reducing the steps of manually lifting the support plate 25, making the process of installing and disassembling the servo drive 50 simpler. In some other embodiments, the reset hole 15 is set through the base 10, and the reset structure 30 includes a reset block 32 and a limit clamping protrusion, the reset block 32 and the limit clamping protrusion are set in the reset hole 15, the limit clamping protrusion is connected to the reset block 32, and the other end of the limit clamping protrusion is clamped on the lower surface of the base 10.

[0062] In one embodiment, a first limiting protrusion 431 is provided on the first latch pin 43, a second limiting protrusion 17 is provided on the inner wall of the first pin hole 16, and the fixing assembly 40 also includes a third elastic member 44, one end of the third elastic member 44 abuts against the second limiting protrusion 17, and the other end of the third elastic member 44 abuts against the first limiting protrusion 431 and is located between the first limiting protrusion 431 and the second limiting protrusion 17, and the third elastic member 44 provides elastic force so that the first latch pin 43 has a tendency to move toward the reset hole 15.

[0063] Specifically, the third elastic member 44 is installed on the second limiting protrusion 17 on the inner wall of the first pin hole 16, and extends along the axial direction of the first pin hole 16 to the first limiting protrusion 431. The distance between the first limiting protrusion 431 and the second limiting protrusion 17 is less than the length of the third elastic member 44 after compression. The third elastic member 44 is arranged in the first pin hole 16 after compression, so that an elastic force can be applied to the first limiting protrusion 431, so that the first latch 43 is pushed inward, and the end of the first latch 43 close to the reset hole 15 abuts against the outer surface of the reset block 32. When the reset block 32 is pressed down to a certain distance to expose the second pin hole 321, the first latch 43 can be automatically inserted into the second pin hole 321 due to the elastic force of the third elastic member 44. The first latch 43 is pulled outward to compress the third elastic member 44, and the reset block 32 can move upward. This arrangement is convenient and simple to operate. When the servo driver 50 is pressed down to the final installation position, the first latch 43 can automatically snap into the second pin hole 321 to fix the reset block 32, which can save the step of manually controlling the insertion of the latch. At the same time, the elastic force provided by the third elastic member 44 can press the first latch 43 against the reset block 32.

[0064] In one embodiment, each clamping member 41 further includes a first rotating shaft 415 and a connecting block 413 , the first rotating shaft 415 is sequentially passed through the connecting block 413 and the connecting rod 414 , and the clamping plate 411 is disposed on the connecting block 413 , so that the clamping plate 411 can rotate relative to the connecting rod 414 .

[0065] Specifically, the connection block 413 is rotatable in the circumferential direction of the first rotating shaft 415, so the clamping plate 411 installed on the connection block 413 can swing within a certain angle range and form a certain angle with the connecting rod 414. If the outer surface of the servo driver 50 is a plane, the clamping plate 411 and the connecting plate are parallel to clamp the servo driver 50; if the outer surface of the clamped servo driver 50 is not a plane, the clamping plate 411 can be rotated to form a certain angle with the connecting rod 414 and then clamp the servo driver 50. This arrangement increases the installation adaptability of the clamping member 41 to servo drivers 50 with different surfaces. In some other embodiments, the clamping plate 411 is fixed to the connecting rod 414.

[0066] In one embodiment, the clamping plate 411 is detachably connected to the connecting block 413 .

[0067] Specifically, at least two screw holes are provided on the surface of the clamping plate 411, and screws are passed through the screw holes and screwed to the connecting block 413. The clamping plate 411 will undergo irreversible deformation after long-term use, which reduces the service life of the clamping plate 411. This arrangement makes it easy to disassemble and replace the clamping plate 411 with a new one after the clamping plate 411 is damaged, thus ensuring the working state of the clamping member 41. In some other embodiments, the clamping plate 411 is welded to the connecting block 413.

[0068] In one embodiment, a buffer pad 412 is provided on a side of the clamping plate 411 facing away from the connecting block 413 , and the buffer pad 412 is used to abut against the servo driver 50 .

[0069] Specifically, when installing the servo driver 50, the clamping plate 411 is clamped inwards, and at this time, the buffer part contacts the servo driver 50 first, and the buffer pad 412 is made of elastic material, and the buffer pad 412 is bonded to the clamping plate 411. In this way, when the buffer part contacts the servo driver 50, the deformation of the buffer part can provide a certain degree of buffering to the servo driver 50, and the outer shell of the servo driver 50 will not be deformed due to excessive clamping force; at the same time, the buffer part is made of elastic material, which can prevent the surface of the servo driver 50 from being scratched during the installation process. In some other embodiments, the buffer pad 412 is at least partially installed on the side of the clamping plate that contacts the servo driver 50.

[0070] In one embodiment, there are multiple support rods 24 , each support rod 24 is connected to the central axis 23 , the multiple support rods 24 are evenly spaced apart in the axial direction of the central axis 23 , and each support rod 24 is connected to the support plate 25 .

[0071] Specifically, multiple support rods 24 are evenly spaced on the central shaft 23, and the multiple support rods 24 support the support plate 25. During the installation of the servo driver 50, the servo driver 50 presses down the support plate 25, and the support plate 25 can evenly distribute the pressure to the central shaft 23 through the multiple support rods 24. This arrangement can make the force on the central shaft 23 uniform and prevent the central shaft 23 from being deformed locally; at the same time, multiple support rods 24 are used to connect the support plate 25, and there are more fulcrums for installation, and the installation of the support plate 25 is also more stable. In some other embodiments, the multiple support rods 24 are randomly distributed in the axial direction of the central shaft 23.

[0072] In one embodiment, the base 10 is further provided with a connecting piece and a fixing through hole 18 , and the connecting piece is connected to the installation wall surface of the base 10 through the fixing through hole 18 to fasten the base 10 .

[0073] Specifically, at least two fixing holes 18 are provided on the base 10, and the connecting member is a screw, a bolt or a pin; in this embodiment, the connecting member is a screw, and the screw passes through the fixing hole 18 and is screwed to the installation wall. In this way, the base 10 can be installed on a variety of different installation walls. More than two fixing holes 18 make the installation of the base 10 more stable, and the connection between the base 10 and the installation wall is detachable. In some other embodiments, the base 10 is bonded to the installation wall.
