[0093] The specific implementation methods of the present application are further described in detail below with reference to the accompanying drawings.

[0094] like Figures 1 to 4 As shown, this embodiment provides a low-voltage cabinet 100 with an automatic cable plugging and unplugging function, including a first cabinet body 10, a second cabinet body 20, a plurality of plugging and unplugging components 30, a sliding component 40, an adjusting component 50, and a driving component 60.

[0095] For the convenience of subsequent reading, the present application introduces a first direction Y, a second direction Z, and a third direction X to describe the embodiments of the present application. The first direction Y, the second direction Z, and the third direction X may be three non-parallel linear directions in space; further, the first direction Y, the second direction Z, and the third direction X may be three mutually perpendicular directions in a three-dimensional coordinate system (three-dimensional Cartesian coordinate system). In the subsequent embodiments, the first direction Y is the Y-axis direction of the coordinate axis of the three-dimensional coordinate system, the second direction Z is the Z-axis direction of the coordinate axis of the three-dimensional coordinate system, and the third direction X is the X-axis direction of the coordinate axis of the three-dimensional coordinate system.

[0096] The first cabinet 10 is provided with electrical components, and the second cabinet 20 is connected to one side of the first cabinet 10 along the first direction Y. A plurality of drawer cavities 11 are provided on the side of the first cabinet 10 away from the second cabinet 20, and a drawer unit 12 is slidably provided in each drawer cavity 11. The drawer unit 12 can be drawn out or put into the drawer cavity 11 along the first direction Y, and the electrical components are placed in the drawer unit 12.

[0097] The second cabinet 20 is provided with cables, and the first cabinet 10 is provided with an interface end 22 on one side close to the second cabinet 20. The number of the interface ends 22 is multiple, and the multiple interface ends 22 are distributed in a rectangular array. The number of cables is multiple, and they are arranged corresponding to the multiple interface ends 22. Each cable can be inserted into the corresponding interface end 22 along the first direction Y, and the interface end 22 is electrically connected to the electrical component, so that the cable can transmit signals such as electrical signals or control signals to the electrical component.

[0098] The second cabinet 20 is provided with an inner cavity 21, and multiple groups of plug-in components 30 are provided in the inner cavity 21, and multiple interface ends 22 are provided on the inner wall of the inner cavity 21 on one side close to the first cabinet 10. Along the second direction Z, multiple groups of plug-in components 30 are arranged at intervals, and each group of plug-in components 30 in the multiple groups of plug-in components 30 includes multiple plug-in components 30. Along the third direction X, multiple plug-in components 30 in the same group of plug-in components 30 are arranged at intervals, and each plug-in component 30 corresponds to a cable to realize plugging and unplugging of the cable and the interface end 22.

[0099] The plug-in and unplugging assembly 30 includes a first sliding structure 31, a first lifting structure 32, and a clamping structure 33. The first sliding structure 31 is transmission-connected to the first lifting structure 32, and is used to drive the first lifting structure 32 to slide along the first direction Y, so as to realize the plug-in and unplugging of the cable along the first direction Y through the first sliding structure 31. The clamping structure 33 includes a fixed clamping plate 332 and a movable clamping plate 331. The fixed clamping plate 332 is transmission-connected to the first sliding structure 31, so that the fixed clamping plate 332 can slide along the first direction Y with the first lifting structure 32. Along the third direction X, the movable clamping plate 331 is arranged on one side of the fixed clamping plate 332, and the first lifting structure 32 is transmission-connected to the movable clamping plate 331, and is used to drive the movable clamping plate 331 to lift and lower along the second direction Z, and the movable clamping plate 331 can slide along the first direction Y with the first lifting structure 32. In this way, both the movable clamping plate 331 and the fixed clamping plate 332 can slide along the first direction Y, so that after the movable clamping plate 331 and the fixed clamping plate 332 clamp the cable and move along the first direction Y, the cable can be driven to move and the cable can be plugged and unplugged.

[0100] The sliding assembly 40 is disposed in the inner cavity 21, and includes a second sliding structure 41 and a plurality of sliding boxes 43. Along the third direction X, the plurality of sliding boxes 43 are arranged at intervals.

[0101] The plurality of sliding boxes 43 are arranged corresponding to the plurality of plug-in assemblies 30 of any group of plug-in assemblies 30, and the second sliding structure 41 is transmission-connected to the plurality of sliding boxes 43, and is used to drive the plurality of sliding boxes 43 to slide synchronously along the third direction X. Along the second direction Z, a mounting cavity 430 is provided at the top of the sliding box 43, and the movable clamping plate 331 can at least partially extend into the mounting cavity 430. The adjustment assembly 50 is arranged in the mounting cavity 430, and the adjustment assembly 50 includes a second adjustment structure 51 and a supporting plate 52. Along the third direction X, the movable clamping plate 331 can slide relative to the first lifting structure 32, and the supporting plate 52 is used to support the movable clamping plate 331 to drive the movable clamping plate 331 to slide along the third direction X. When the second sliding structure 41 drives the sliding box 43 to slide along the third direction X, the sliding box 43 pushes the movable clamping plate 331 to slide along the third direction X through the supporting plate 52, thereby realizing that the movable clamping plate 331 is close to the fixed clamping plate 332.

[0102] The second adjustment structure 51 is transmission-connected to the abutment plate 52, and is used to drive the abutment plate 52 to slide along the third direction X, so as to adjust the distance between the abutment plate 52 and the movable clamping plate 331 along the third direction X, so that each sliding box 43 needs to move different distances during the synchronous sliding process to make the abutment plate 52 abut against the movable clamping plate 331, thereby enabling each plug-in assembly 30 in the same group of plug-in assemblies 30 to plug in and out cables with different outer diameters.

[0103] The driving assembly 60 is disposed in the inner cavity 21, and the driving assembly includes a second lifting structure 61 and a driving structure 62. The driving structure 62 is disposed corresponding to any group of plug-in and unplug-in assemblies 30, and the second lifting structure 61 is connected to the driving structure 62 in a transmission manner, and is used to drive the driving structure 62 to rise and fall along the second direction Z, so as to cooperate with any group of plug-in and unplug-in assemblies 30. The driving structure 62 is selectively connected to each first sliding structure 31 in a group of plug-in and unplug-in assemblies 30 in a transmission manner, and is used to selectively provide driving force to each first sliding structure 31 in a group of plug-in and unplug-in assemblies 30, so as to selectively realize the plug-in and unplugging of cables.

[0104] In this way, in the low-voltage cabinet 100 with the automatic plug-in and unplug function of the present application, multiple sliding boxes 43 are driven by the same second sliding structure 41 to realize the moving clamping plate 331 approaching or moving away from the fixed clamping plate 332 along the third direction X, which greatly reduces the structural complexity of the entire low-voltage cabinet and reduces the manufacturing cost. At the same time, the first lifting structure 32 can not only drive the moving clamping plate 331 to approach the positioning plate along the second direction Z to press the cable, but also make the moving clamping plate 331 partially extend into the sliding box 43 through the first lifting structure 32 and move along the third direction X with the sliding box 43. Furthermore, the adjustment component 50 set in the sliding box 43 can adjust the spacing between each abutting plate 52 and the moving clamping plate 331 by adjusting the working state of the second adjustment structure 51 in each sliding box 43, so that each clamping structure 33 can clamp cables with different outer diameters. In addition, the second lifting structure 61 can make the driving structure 62 cooperate with different groups of plug-in components 30 after lifting, so that each plug-in component 30 shares a group of driving structures 62, which can reduce costs. The driving structure 62 selectively drives the plugging and unplugging components 30 required to work in a group of plugging and unplugging components 30 to realize the plugging and unplugging of corresponding cables, thereby selectively plugging and unplugging any number of cables in the same row.

[0105] Please combine again Figures 1 to 4 In one embodiment, the first sliding structure 31 includes a first lead screw 311 and a first sleeve 312. The first lead screw 311 is arranged along the first direction Y, and the first sleeve 312 is sleeved on the outer circumferential surface of the first lead screw 311 and threadedly engaged with the first lead screw 311. The first lead screw 311 is used to drive the first sleeve 312 to slide along the first direction Y. One end of the first lead screw 311 is rotatably mounted on the inner wall of the inner cavity 21 on the side close to the first cabinet 10, and the other end of the first lead screw 311 is spaced apart from the inner wall of the inner cavity 21 on the side away from the first cabinet 10.

[0106] The first lifting structure 32 includes a lifting drive member 321 and a lifting plate 322. The lifting drive member 321 is a cylinder, and the lifting drive member 321 can be connected to the bottom end of the first sliding sleeve 312 through a cylinder mounting plate, so that the lifting drive member 321 slides along the first sliding sleeve 312 in the first direction Y. The lifting plate 322 is arranged at the bottom end of the lifting drive member 321, and the lifting drive member 321 is transmission-connected to the lifting plate 322, and is used to drive the lifting plate 322 to rise and fall along the second direction Z.

[0107] In this embodiment, the fixed clamping plate 332 is connected to the first sliding sleeve 312. Along the third direction X, a connecting rod 35 is connected to the right side of the first sliding sleeve 312. The connecting rod 35 is substantially "L" shaped, and one end of the connecting rod 35 away from the first sliding sleeve 312 is connected to the fixed clamping plate 332.

[0108] Along the third direction X, the movable clamping plate 331 is slidably connected to the lifting plate 322 to ensure that the movable clamping plate 331 can slide relative to the lifting plate 322 along the third direction X with the sliding box 43. The movable clamping plate 331 is used to approach the fixed clamping plate 332 along the second direction Z and / or the third direction X to clamp the cable.

[0109] The movable clamping plate 331 approaches the fixed clamping plate 332 along the third direction X to clamp the cable in the third direction X. The movable clamping plate 331 approaches the fixed clamping plate 332 along the second direction Z to press the cable in the second direction Z to prevent the cable from warping after being clamped in the third direction X, thereby ensuring accuracy during subsequent cable plugging and unplugging.

[0110] In this embodiment, the fixed clamping plate 332 and the movable clamping plate 331 are both in an "L" shape.

[0111] The fixed clamping plate 332 includes a first fixed area portion 3321 and a second fixed area portion 3322, both of which are flat plate structures. The first fixed area portion 3321 is arranged along the second direction Z, and the second fixed area portion 3322 is arranged along the third direction X. The second fixed area portion 3322 is connected to the bottom end of the first fixed area portion 3321 on one side close to the movable clamping plate 331 along the third direction X, and the second fixed area portion 3322 is used to place cables.

[0112] The movable clamping plate 331 includes a first movable area portion 3311 and a second movable area portion 3312, and the first movable area portion 3311 and the second movable area portion 3312 are both flat plate structures. The first movable area portion 3311 is arranged along the second direction Z, and the second movable area portion 3312 is arranged along the third direction X, and the second movable area portion 3312 is connected to the top of the first movable area portion 3311 on one side close to the fixed clamping plate 332 along the third direction X. Among them, along the second direction Z, the second movable area portion 3312 is spaced above the second fixed area portion 3322, so that the cable can be compressed between the second movable area portion 3312 and the second fixed area portion 3322.

[0113] It is worth noting that the fixed clamping plate 332 plays a role in positioning the cable to ensure that the cable can be accurately inserted into the interface end 22. When the first movable area portion 3311 presses the cable against the first fixed area portion 3321 in the third direction X, and the second movable area portion 3312 presses the cable against the second fixed area portion 3322 in the second direction Z, the first fixed area portion 3321 and the second fixed area portion 3322 limit the cable in the second direction Z and the third direction X, ensuring that the cable clamped by the passive clamping plate 331 and the fixed clamping plate 332 can be accurately inserted into the interface end 22.

[0114] Please combine again Figures 2 to 5 In one embodiment, the clamping structure 33 further includes a mounting plate 34, which is disposed on a side of the lifting plate 322 away from the lifting driving member 321. A sliding protrusion 341 is convexly disposed on a side of the mounting plate 34 close to the lifting plate 322, and a sliding groove 3220 is disposed along a third direction X on a side of the lifting plate 322 close to the mounting plate 34. The sliding protrusion 341 is slidably disposed in the sliding groove 3220, so that the mounting plate 34 can slide relative to the lifting plate 322 along the third direction X.

[0115] The movable clamping plate 331 is connected to the side of the mounting plate 34 away from the lifting plate 322. A connecting rod 36 is provided between the movable clamping plate 331 and the mounting plate 34, and the shape of the connecting rod 36 is roughly "L"-shaped. One end of the connecting rod 36 is connected to the mounting plate 34, and the other end thereof is connected to the first movable section 3311. A supporting protrusion 342 is provided on the side of the mounting plate 34 away from the lifting plate 322, and the supporting protrusion 342 is arranged at intervals on the side of the connecting rod 36 away from the first cabinet 10 along the first direction Y. The supporting protrusion 342 is a flat plate structure and is arranged along the first direction Y. The supporting protrusion 342 is used to support the supporting plate 52 along the third direction X. The supporting plate 52 pushes the mounting plate 34 to slide rightward along the third direction X by supporting the supporting protrusion 342, thereby driving the movable clamping plate 331 to approach the fixed clamping plate 332 along the third direction X.

[0116] In particular, the length of the sliding box 43 along the first direction Y should be large enough so that when the movable clamping plate 331 and the fixed clamping plate 332 clamp the cable along the first direction Y for wiring operation, the supporting protrusion 342 is always located in the mounting cavity 430 and is in a state of being pressed tightly by the supporting plate 52, thereby ensuring the stability of cable clamping.

[0117] It is worth noting that when the cable needs to be loosened, the sliding box 43 moves to the left along the third direction X, the installation cavity 430 abuts against the abutting protrusion 342 on the right inner wall along the third direction X, and then pushes the installation plate 34 to slide to the left along the third direction X, thereby driving the movable clamping plate 331 away from the fixed clamping plate 332 along the third direction X, thereby loosening the cable.

[0118] In this embodiment, the second adjustment structure 51 is configured as an electromagnetic spring. The electromagnetic spring is disposed on the inner wall of the installation cavity 430 on the left side along the third direction X, and the electromagnetic spring is disposed along the third direction X. The abutting plate 52 is transmission-connected to the electromagnetic spring, and the electromagnetic spring can drive the abutting plate 52 to move back and forth along the third direction X after being energized, and the electromagnetic spring is configured to adjust the moving distance of the abutting plate 52 along the third direction X based on the magnitude of the current connected thereto, thereby realizing that each sliding box 43 needs to move a different distance when moving synchronously before starting to push the movable clamping plate 331 close to the fixed clamping plate 332, so that when each sliding box 43 stops moving, each sliding box 43 pushes the corresponding movable clamping plate 331 to press the cable against the fixed clamping plate 332, thereby realizing synchronous clamping of the cable.

[0119] Please combine again Figures 2 to 4 In one embodiment, the number of sliding components 40 is multiple and corresponds to the number of multiple sets of plug-in components 30, so that each sliding component 40 acts on the corresponding plug-in component 30.

[0120] The second sliding structure 41 includes a second lead screw 411 and a second sleeve 412. The second lead screw 411 is arranged along the third direction X, and the two ends of the second lead screw 411 are rotatably mounted on the inner walls of the left and right sides of the inner cavity 21 respectively. The second lead screw 411 is transmission-connected to a motor to drive the second lead screw 411 to rotate through the motor, and the motor is mounted on the inner wall of the inner cavity 21. The second sleeve 412 is sleeved on the outer circumference of the second lead screw 411, and the second sleeve 412 is threadedly matched with the second lead screw 411, and the second lead screw 411 is used to drive the second sleeve 412 to slide along the third direction X. Each sliding box 43 is connected to at least one second sleeve 412, so that the sliding box 43 is driven to slide back and forth along the third direction X through the second sleeve 412.

[0121] Please combine again Figures 5 to 7 In one embodiment, the driving assembly 60 further includes a height adjustment plate 63. The second lifting structure 61 is transmission-connected to the height adjustment plate 63, and is used to drive the height adjustment plate 63 to rise and fall along the second direction Z. Along the first direction Y, the height adjustment plate 63 is arranged at intervals at the end of the first lead screw 311 away from the first cabinet 10, and the driving structure 62 is installed on the side of the height adjustment plate 63 close to the first lead screw 311, so as to utilize the space between the first lead screw 311 and the inner wall of the inner cavity 21 on the side away from the first cabinet 10 to install the height adjustment plate 63 and the driving structure 62, so as to avoid the volume of the entire cabinet being too large, and the driving structure 62 can be used in conjunction with the plug-in assembly 30 of different heights after the height adjustment plate 63 is raised and lowered.

[0122] The second lifting structure 61 includes a third lead screw 611 and a third sleeve 612. The third lead screw 611 is arranged along the second direction Z, and its upper and lower ends are rotatably mounted on the top wall and the bottom wall of the inner cavity 21, respectively. The third lead screw 611 is driven by a motor to rotate. The third sleeve 612 is sleeved on the outer circumference of the third lead screw 611 and is threadedly matched with the third lead screw 611, so that the third sleeve 612 is driven to rise and fall along the second direction Z by the rotation of the third lead screw 611. The height adjustment plate 63 is connected to the third sleeve 612 to rise and fall with the third sleeve 612.

[0123] In this embodiment, the number of the second lifting structures 61 is two, and the two second lifting structures 61 are arranged at intervals along the third direction X, and the two second lifting structures 61 are respectively arranged close to the inner walls of the inner cavity 21 on the left and right sides along the third direction X. The shape of the height adjustment plate 63 is roughly "U"-shaped, and the two ends of the height adjustment plate 63 are respectively connected to the two third sliding sleeves 612, and the middle part of the height adjustment plate 63 is arranged close to the inner wall of the inner cavity 21 on the side away from the first cabinet 10, so as to reasonably utilize the space of the inner cavity 21 for installation, so that the structure of the entire cabinet is more compact. The two second lifting structures 61 share a motor as a driving source, and the two third lead screws 611 of the two second lifting structures 61 are connected by a synchronous belt and a synchronous wheel transmission to achieve synchronous rotation of the two.

[0124] The driving structure 62 includes a rotating driving member 621, a driving wheel 622, a plurality of driven wheels 623, and a transmission belt 624. The axes of the driving wheel 622 and the plurality of driven wheels 623 are parallel to the first direction Y. The rotating driving member 621 is a device such as a motor, and is fixed on the height adjustment plate 63.

[0125] The rotation driving member 621 is installed in the middle part of the height adjustment plate 63, and is connected to the driving wheel 622 by transmission to drive the driving wheel 622 to rotate. Along the third direction, multiple driven wheels 623 are arranged at intervals and corresponding to multiple first lead screws 311 of the same group, and the driven wheels 623 are coaxially arranged with the corresponding first lead screws 311. Multiple driven wheels 623 are rotatably installed on one side of the height adjustment plate 63 close to the first lead screw 311, and the driving wheel 622 drives the multiple driven wheels 623 to rotate synchronously through the transmission belt 624.

[0126] An intermediate transmission structure 64 is provided on one side of each driven wheel 623 close to the first lead screw 311 , and the intermediate transmission structure 64 is used to selectively drive the corresponding first lead screw 311 to rotate.

[0127] The intermediate transmission structure 64 includes a rotating plate 641, a first adjustment structure 642, a first clamping wheel 643, and a second clamping wheel 644. The rotating plate 641 is coaxially connected to the driven wheel 623 through a connecting rod, so that the driven wheel 623 drives the rotating plate 641 to rotate synchronously. The first adjustment structure 642 is configured as an electromagnetic spring and is disposed on a side of the rotating plate 641 close to the first lead screw 311. The first adjustment structure 642 can rotate synchronously with the rotating plate 641. The first clamping wheel 643 is disposed at the driving end of the first adjustment structure 642. The first clamping wheel 643 can rotate synchronously with the first adjustment structure 642. The second clamping wheel 644 is coaxially connected to the first lead screw 311, and the first lead screw 311 can be driven to rotate through the second clamping wheel 644. The first clamping wheel 643 is used to be movably engaged with the second clamping wheel 644. The first adjustment structure 642 is set along the first direction Y. The first adjustment structure 642 is configured to adjust the moving distance of the first clamping wheel 643 along the first direction Y based on the size of the current it is connected to, so as to make the first clamping wheel 643 approach or move away from the second clamping wheel 644, thereby realizing the engagement or separation of the first clamping wheel 643 and the second clamping wheel 644.

[0128] When the first holding wheel 643 is engaged with the second holding wheel 644, the first holding wheel 643 drives the second holding wheel 644 to rotate, and then the second holding wheel 644 drives the first lead screw 311 connected thereto to rotate, and then the clamping structure 33 corresponding to the first lead screw 311 moves to realize the plugging and unplugging of the cable. When the first holding wheel 643 is separated from the second holding wheel 644, the first holding wheel 643 will not drive the second holding wheel 644 to rotate during the rotation process, and then the first lead screw 311 corresponding to the first holding wheel 643 is in a non-rotating state, so that the clamping structure 33 corresponding to the first lead screw 311 will not move.

[0129] Furthermore, a clamping protrusion 6430 is convexly provided on one side of the first clamping wheel 643 close to the second clamping wheel 644, and a clamping groove 6440 is concavely provided on one side of the second clamping wheel 644 close to the first clamping wheel 643. The clamping protrusion 6430 is matched with the clamping groove 6440, and the clamping protrusion 6430 can be clamped in the clamping groove 6440, and when the clamping protrusion 6430 can be clamped in the clamping groove 6440, the outer circumference of the clamping protrusion 6430 abuts against the inner circumference of the clamping groove 6440.

[0130] Here is an explanation of how this application works:

[0131] When some cables in the same row need to be clamped, the current connected to the corresponding second adjustment structures 51 is adjusted according to the outer diameter of the cables to be clamped, thereby adjusting the initial distance between the abutting plate 52 and the movable clamping plate 331. Subsequently, the lifting drive member 321 corresponding to the cables to be clamped is controlled to move so as to lower the abutting protrusions 342 corresponding to the cables to be clamped to enter the installation cavity 430, while the abutting protrusions 342 corresponding to the cables that do not need to be clamped remain outside the installation cavity 430. Subsequently, the second lead screw 411 rotates to drive the sliding box 43. After each sliding box 43 moves a different distance, it starts to push against the movable clamping plate 331 to slide toward the fixed clamping plate 332. After each movable clamping plate 331 presses the cable against the fixed clamping plate 332 along the third direction X, the second lead screw 411 stops rotating and controls each lifting drive member 321 to continue to move, and adjusts the descending distance of the lifting plate 322 according to the outer diameter of the cable corresponding to each lifting drive member 321, so that each movable clamping plate 331 presses the cable against the fixed clamping plate 332 in the second direction Z. Next, the first lead screw 311 rotates to control the movable clamping plate 331 and the fixed clamping plate 332 to move the clamped cable toward the interface end 22 until the cable is inserted into the interface end 22. During this process, the pushing protrusion 342 is always located in the sliding box 43.

[0132] After the cable is inserted into the interface end 22, the second lead screw 411 rotates in the opposite direction, and the sliding box 43 moves leftward along the third direction X, and drives the moving clamping plate 331 away from the fixed clamping plate 332. Subsequently, the lifting drive member 321 drives the abutting protrusion 342 to leave the sliding box 43, thereby completely loosening the cable.

[0133] In the above, the specific embodiments of the present application are described with reference to the accompanying drawings. However, those skilled in the art will appreciate that various changes and substitutions may be made to the specific embodiments of the present application without departing from the scope of the present application. These changes and substitutions are all within the scope defined by the present application.
