[0006] In a possible implementation, along the second direction, when the sliding mechanism drives the lifting mechanism to slide away from the first driving wheel and the second driving wheel, the second driving member drives the first driving wheel and the second driving wheel to lift through the one-way transmission mechanism;

[0007] Along the second direction, when the sliding mechanism drives the lifting mechanism to slide towards the first driving wheel and the second driving wheel, the second driving member is in a state of being disengaged from the one-way transmission mechanism.

[0014] In a possible implementation, the third driving assembly further includes a jacking mechanism. The one-way transmission mechanism includes a rack, a third transmission wheel, a first ratchet wheel, and a second ratchet wheel. The rack is arranged along the second direction and is connected to the push rod. Along the third direction, the third transmission wheel meshes with one side of the rack. The third direction is perpendicular to the second direction. The third transmission wheel is coaxially arranged with the first ratchet wheel.

In addition, unless clearly defined in the text, terms such as those defined in a general dictionary should be interpreted as having a meaning consistent with their meaning in the relevant art and the content of this application, and will not be interpreted in an idealized or overly formal sense.

[0030] The following will further describe in detail the specific embodiments of the present application with reference to the accompanying drawings.

[0031] As Figures 1 to 4 shown, this embodiment provides a switchgear cabinet 100 with a chamber adjustment function, and the switchgear cabinet 100 with a chamber adjustment function can be used for switchgear cabinets of types such as low-voltage switchgear cabinets.

[0032] For the convenience of subsequent reading, the present application introduces the first direction Z, the second direction Y, and the third direction X to describe the embodiments of the present application. The first direction Z, the second direction Y, and the third direction X can be three non-parallel straight-line directions in space; further, the first direction Z, the second direction Y, and the third direction X can be three mutually perpendicular directions in a three-dimensional coordinate system (three-dimensional Cartesian coordinate system). In subsequent embodiments, the first direction Z is taken as the Z-axis direction of the coordinate axis of the three-dimensional coordinate system, the second direction Y is taken as the Y-axis direction of the coordinate axis of the three-dimensional coordinate system, and the third direction X is taken as the X-axis direction of the coordinate axis of the three-dimensional coordinate system as an example for description.

[0033] The switch cabinet 100 with chamber adjustment function includes a cabinet body 10, a first drive assembly 30, multiple second drive assemblies 40, and multiple third drive assemblies 50. The cabinet body 10 is provided with an installation cavity, and multiple lifting plates 20 are provided in the installation cavity. The multiple lifting plates 20 are arranged in sequence and spaced apart along the first direction Z. The lifting plates 20 can be raised and lowered relative to the cabinet body 10. The lifting plates 20 are configured to support drawer units 21. The space between two adjacent lifting plates 20 can form a accommodating cavity for accommodating the drawer units 21. The size of the accommodating cavity can be changed by adjusting the position of the two lifting plates 20 forming the accommodating cavity in the first direction Z, thereby accommodating drawer units 21 of different sizes. The first drive assembly 30 includes a first driving member 31 and a driving shaft 32. The driving shaft 32 is arranged along the first direction Z. The first driving member 31 is configured to drive the driving shaft 32 to rotate. Multiple second drive assemblies 40 are disposed corresponding to the multiple lifting plates 20. Each second drive assembly 40 includes a lifting mechanism 43, a first driving wheel 41, and a second driving wheel 42. The first drive member 31 is configured to drive the first driving wheel 41 and the second driving wheel 42 to rotate. The first driving wheel 41 and the second driving wheel 42 rotate in opposite directions. The first driving wheel 41 and the second driving wheel 42 can be raised and lowered relative to the driving shaft 32 along the first direction Z. The lifting mechanism 43 is transmission-connected to its corresponding lifting plate 20 and is transmission-connected to the first driving wheel 41 or the second driving wheel 42. Multiple third drive assemblies 50 are disposed corresponding to the multiple second drive assemblies 40. The third drive assembly 50 is configured to drive the first driving wheel 41 and the second driving wheel 42 of its corresponding second drive assembly 40 to rise and fall along the first direction Z. In the second direction Y, the third drive assembly 50 is also configured to drive the lifting mechanism 43 of its corresponding second drive assembly 40 to move relative to the first driving wheel 41 and the second driving wheel 42.

[0034] Thus, in the switch cabinet 100 with chamber adjustment function of the present application, the drawer unit 21 is placed on the lifting plate 20, and each lifting plate 20 can be independently lifted and lowered to adjust the size of the chamber for accommodating the drawer unit 21 formed between any two adjacent lifting plates 20, so that the various chambers of the switch cabinet can be adjusted based on actual project requirements to accommodate drawer units 21 of different sizes. In addition, the present application adopts a single first drive assembly 30 to provide power for the lifting and lowering of each lifting plate 20 at the same time, and through the cooperation of multiple second drive assemblies 40 and multiple third drive assemblies 50, the state adjustment of the driving force of each lifting plate 20 is achieved, so that under the action of the single first drive assembly 30, some lifting plates 20 can rise, some lifting plates 20 can fall, and some lifting plates 20 can remain in position unchanged, thereby quickly achieving the position adjustment of each lifting plate 20 according to preset requirements.

[0035] Please combine again Figures 1 to 4In one embodiment, a mounting opening 11 is defined on one side of the cabinet body 10 along the second direction Y, communicating with the accommodating cavity. A lifting plate 20 is partially located within the accommodating cavity and slidably connected to the cabinet body 10 along the second direction Y. The lifting plate 20 is also partially located within the mounting opening 11, allowing the lifting plate 20 to slide up and down along the walls of the mounting opening 11. A drawer unit 21 is slidably connected to the lifting plate 20 along the second direction Y, facilitating removal of the drawer unit 21 from the mounting opening 11.

[0036] In other embodiments, the lifting plates 20 spaced apart along the first direction Z along the third direction X form a group of lifting plates 20, and the lifting plates 20 are provided in two, three, or other groups. The multiple groups of lifting plates 20 are spaced apart along the third direction X, and each group of lifting plates 20 is provided with a driving shaft 32 to provide driving force thereto. The driving shafts 32 provided in the multiple groups of lifting plates 20 share a common first driving member 31. For example, the first driving member 31 synchronously drives the multiple driving shafts 32 via a belt transmission mechanism.

[0037] Please combine again Figures 3 to 5 In one embodiment, the third driving assembly 50 includes a second driving member 51, a sliding mechanism 52 and a one-way transmission mechanism 53. It is worth noting that Figure 3 and Figure 4 The positional relationship of the second drive assembly 40 and the third drive assembly 50 relative to the first drive assembly 30 is shown only to better illustrate the various components and the coordination relationship between the various components. In the actual manufacturing process, in order to ensure that the distance between two adjacent lifting plates 20 in the first direction Z remains within an appropriate range, the positions of the second drive assembly 40 and the third drive assembly 50 relative to the first drive assembly 30 and the sizes of the various components will be adaptively adjusted according to the actual space size. The second drive member 51 is connected in a transmission manner to the sliding mechanism 52 and the one-way transmission mechanism 53, and is used to provide a first driving force to the sliding mechanism 52 and a second driving force to the one-way transmission mechanism 53. Based on the first driving force, the sliding mechanism 52 drives the lifting mechanism 43 to slide along the second direction Y. Based on the second driving force, the one-way transmission mechanism 53 is connected in a transmission manner to the first driving wheel 41 and the second driving wheel 42, and is used to drive the first driving wheel 41 and the second driving wheel 42 to rise and fall.

[0038] When the sliding mechanism 52 drives the lifting mechanism 43 to slide toward the side away from the first driving wheel 41 and the second driving wheel 42 along the second direction Y, the second driving member 51 drives the first driving wheel 41 and the second driving wheel 42 to move up and down through the one-way transmission mechanism 53 .

[0039] When the sliding mechanism 52 drives the lifting mechanism 43 to slide toward the side close to the first driving wheel 41 and the second driving wheel 42 along the second direction Y, the second driving member 51 and the one-way transmission mechanism 53 are in a disengaged transmission connection state, that is, the second driving member 51 does not provide the second driving force to the one-way transmission mechanism 53. At this time, the one-way transmission mechanism 53 does not drive the first driving wheel 41 and the second driving wheel 42 to lift.

[0040] In this way, when it is necessary to drive the first driving wheel 41 and the second driving wheel 42 to lift, the second driving member 51 drives the lifting mechanism 43 to slide away from the first driving wheel 41 and the second driving wheel 42 through the sliding mechanism 52, so that the lifting mechanism 43 is disengaged from the transmission connection relationship with the first driving wheel 41 or the second driving wheel 42, avoiding the influence of the lifting mechanism 43 on the lifting of the first driving wheel 41 and the second driving wheel 42. In addition, when the second driving member 51 works, the second driving member 51 also drives the first driving wheel 41 and the second driving wheel 42 to lift synchronously through the one-way transmission mechanism 53 until one of the first driving wheel 41 and the second driving wheel 42 is at the same height as the lifting mechanism 43, or neither the first driving wheel 41 nor the second driving wheel 42 is at the same height as the lifting mechanism 43, and then the second driving member 51 acts in the reverse direction to drive the lifting mechanism 43 to slide toward the side close to the first driving wheel 41 and the second driving wheel 42, thereby completing the switching of the driving mode.

[0041] Please also combine Figures 3 to 5 In an embodiment, the second driving assembly 40 further includes a first shaft sleeve 45, a second shaft sleeve 46, and a third driving wheel 47. Both the first shaft sleeve 45 and the second shaft sleeve 46 are hollow cylindrical structures. Along the first direction Z, both ends of the driving shaft 32 are rotatably connected to the upper and lower cavity walls of the installation cavity respectively. The first driving member 31 is a motor, and the motor is installed in the installation cavity and drives the driving shaft 32 to rotate through the motor.

[0042] Along the first direction Z, the first shaft sleeve 45 and the second shaft sleeve 46 of each second driving assembly 40 are sequentially and spacedly sleeved on the outer peripheral surface of the driving shaft 32, and the first shaft sleeve 45 is located below the corresponding second shaft sleeve 46. The driving shaft 32 can rotate relative to the first shaft sleeve 45 and the second shaft sleeve 46, and the first shaft sleeve 45 and the second shaft sleeve 46 can move up and down along the first direction Z relative to the driving shaft 32. The first shaft sleeve 45 and the second shaft sleeve 46 can be slidably connected to the inner wall of the cabinet body 10 through the slide plates 440 respectively.

[0043] The first driving wheel 41 is rotatably sleeved on the outer peripheral surface of the first shaft sleeve 45, that is, the first driving wheel 41 can rotate relative to the first shaft sleeve 45 around the axis of the driving shaft 32, and the first driving wheel 41 can move up and down along the first direction Z together with the first shaft sleeve 45. Along the first direction Z, the third driving wheel 47 can slide relative to the driving shaft 32, and the driving shaft 32 drives the third driving wheel 47 to rotate. The third driving wheel 47 is sleeved on the outer peripheral surface of the driving shaft 32, and the third driving wheel 47 is located between the first shaft sleeve 45 and the second shaft sleeve 46, so that when the first shaft sleeve 45 slides upward, the first shaft sleeve 45 pushes the third driving wheel 47 to slide upward, and the third driving wheel 47 further pushes the second shaft sleeve 46 to slide upward. Specifically, a keyway can be formed on the inner peripheral surface of the third driving wheel 47, and a connecting key can be provided on the outer peripheral surface of the driving shaft 32. The connecting key cooperates with the keyway, so that when the third driving wheel 47 slides along the axis of the driving shaft 32, the driving shaft 32 can also drive the third driving wheel 47 to rotate.

[0044] The second driving wheel 42 is sleeved on the outer peripheral surface of the driving shaft 32. Along the first direction Z, the second driving wheel 42 is located above the second shaft sleeve 46. When the second shaft sleeve 46 moves upward, the second shaft sleeve 46 can abut against the second driving wheel 42 to slide upward relative to the driving shaft 32, and the driving wheel drives the second driving wheel 42 to rotate. The connection relationship between the second driving wheel 42 and the driving shaft 32 can also adopt a key structure, that is, the same as the connection relationship between the above-mentioned third driving wheel 47 and the driving shaft 32, which will not be elaborated here.

[0045] In this embodiment, the second driving assembly 40 further includes a reverse transmission mechanism 44. The third driving wheel 47 drives the first driving wheel 41 to rotate through the reverse transmission mechanism 44, and the rotation direction of the first driving wheel 41 is opposite to that of the third driving wheel 47.

[0046] The reverse transmission mechanism 44 includes a first transmission wheel 441 and a second transmission wheel 442. The first transmission wheel 441 is located between the third driving wheel 47 and the second transmission wheel 442, and the third driving wheel 47 and the second transmission wheel 442 are respectively engaged on the opposite sides of the first transmission wheel 441, and the second transmission wheel 442 is engaged with the first driving wheel 41. Thus, when the driving shaft 32 drives the third driving wheel 47 to rotate counterclockwise, the third driving wheel 47 drives the first transmission wheel 441 to rotate clockwise, the first transmission wheel 441 drives the second transmission wheel 442 to rotate counterclockwise, and the second transmission wheel 442 drives the first driving wheel 41 to rotate clockwise. In addition, the driving shaft 32 drives the second driving wheel 42 to rotate counterclockwise, so as to realize the rotation actions with opposite rotation directions of the first driving wheel 41 and the second driving wheel 42 under the drive of the driving shaft 32.

[0047] It should be noted that the above-mentioned slide plate 440 is provided on the outer peripheral surface of the second bushing 46. One end of the slide plate 440 is connected to the outer peripheral surface of the second bushing 46, and the other end of the slide plate 440 is slidably connected to the cavity wall of the cabinet body 10. The first driving wheel 441 and the second driving wheel 442 are rotatably connected to the slide plate 440 to ensure that the first driving wheel 441 and the second driving wheel 442 slide synchronously with the first driving wheel 41 and the third driving wheel 47.

[0048] Please also combine with Figures 3 to 5 , in an embodiment, the sliding mechanism 52 includes a mounting plate 522 and a push rod 521. Along the second direction Y, the lifting mechanism 43 is slidably connected to the mounting plate 522. The second driving member 51 is connected to the mounting plate 522. One end of the push rod 521 is connected to the driving end of the second driving member 51, and the other end of the push rod 521 is connected to the lifting mechanism 43 to drive the lifting mechanism 43 to slide along the second direction Y through the second driving member 51.

[0049] The mounting plate 522 is fixed to the cavity wall of the cabinet body 10, and the second driving member 51 is an electromagnetic spring, which is mounted on the top surface of the mounting plate 522. Based on the energized state of the electromagnetic spring, the electromagnetic spring can drive the push rod 521 to slide back and forth along the second direction Y. It should be noted that in other embodiments, the second driving member 51 can also adopt driving members such as push-pull cylinders. The second driving member 51 adopts an electromagnetic spring, and its cost is lower than that of driving members such as push-pull cylinders.

[0050] The lifting mechanism 43 includes a first lead screw 432, a lead screw sliding sleeve 434, a lead screw connecting plate 433, and a driven wheel 431. The first lead screw 432 is arranged along the first direction Z and is rotatably connected to the lead screw connecting plate 433. Along the second direction Y, the lead screw connecting plate 433 is slidably connected to the mounting plate 522. A strip-shaped hole 5220 is formed in the mounting plate 522. Along the first direction Z, the strip-shaped hole 5220 penetrates through the mounting plate 522, and the strip-shaped hole 5220 is arranged along the second direction Y. The bottom end of the first lead screw 432 can pass through the strip-shaped hole 5220, and the driven wheel 431 is sleeved on the outer peripheral surface of the bottom end of the first lead screw 432 passing through the strip-shaped hole 5220.

[0051] The lead screw sliding sleeve 434 is sleeved on the outer peripheral surface of the first lead screw 432, and the lead screw sliding sleeve 434 is in threaded cooperation with the first lead screw 432. When the first lead screw 432 rotates, the first lead screw 432 can drive the lead screw sliding sleeve 434 to slide along the extension direction of the first lead screw 432. The lifting plate 20 is connected to the lead screw sliding sleeve 434 to drive the lifting plate 20 to lift and lower synchronously along the first direction Z through the lead screw sliding sleeve 434.

[0052] Along the second direction Y, the lifting plate 20 can slide relative to the lead screw sleeve 434. Specifically, a connecting rod 22 is provided on the lifting plate 20 and connected thereto. The connecting rod 22 is generally in a "U" shape, and the middle section of the connecting rod 22 is arranged along the second direction Y. A through hole 4340 is formed in the lead screw sleeve 434. Along the second direction Y, the through hole 4340 penetrates through the lead screw sleeve 434, and the middle section of the connecting rod 22 is inserted into the through hole 4340, so that the lead screw sleeve 434 can slide relative to the connecting rod 22 along the second direction Y.

[0053] The driven wheel 431 is sleeved on the outer peripheral surface of the first lead screw 432, and the driven wheel 431 is fixedly connected to the first lead screw 432 to drive the first lead screw 432 to rotate through the driven wheel 431. The driven wheel 431 can be selectively engaged with the first driving wheel 41 or the second driving wheel 42. The rotation axes of the driven wheel 431, the first driving wheel 41, and the second driving wheel 42 are arranged parallel to each other.

[0054] Please also combine Figures 3 to 7 In an embodiment, the one-way transmission mechanism 53 includes a rack 531, a third transmission wheel 532, a first ratchet wheel 534, and a second ratchet wheel 535. The rack 531 is arranged along the second direction Y, and the rack 531 is connected to the push rod 521. It can be understood that the rack 531 can also be integrally formed with the push rod 521.

[0055] The third transmission wheel 532 is rotatably connected to the top surface of the mounting plate 522, and the direction of the rotation axis of the third transmission wheel 532 is parallel to the first direction Z. Along the third direction X, the third transmission wheel 532 meshes with one side of the rack 531, so that when the rack 531 slides along the second direction Y with the push rod 521, the rack 531 can drive the third transmission wheel 532 to rotate. The third transmission wheel 532 is coaxially arranged with the first ratchet wheel 534, and the first ratchet wheel 534 is connected to the second ratchet wheel 535 in a one-way transmission manner.

[0056] Further, the one-way transmission mechanism 53 further includes a first transmission shaft 533, a second transmission shaft 536, a third transmission shaft 539, a first bevel gear 537, and a second bevel gear 538. The first transmission shaft 533 is arranged along the first direction Z. One end of the first transmission shaft 533 is coaxially fixed to the third transmission wheel 532, and the other end of the first transmission shaft 533 is coaxially fixed to the first ratchet wheel 534. The second ratchet wheel 535 is arranged on one side of the first ratchet wheel 534, and the first ratchet wheel 534 is in one-way transmission connection with the second ratchet wheel 535. The third driving assembly 50 further includes a jacking mechanism 54. The second ratchet wheel 535 is configured to provide a driving force for the jacking mechanism 54, so that the jacking mechanism 54 jacks up the first driving wheel 41 to mesh with the driven wheel 431 or the second driving wheel 42 to mesh with the driven wheel 431. In this way, when the second driving member 51 drives the driven wheel 431 to slide along the second direction Y away from the first driving wheel 41 and the second driving wheel 42, the first rack 531 drives the third transmission wheel 532 to rotate. The third transmission wheel 532 drives the first ratchet wheel 534 to rotate. Along the rotation direction of the first ratchet wheel 534, the ratchet teeth of the first ratchet wheel 534 abut against the ratchet teeth of the second ratchet wheel 535. Further, the first ratchet wheel 534 drives the second ratchet wheel 535 to rotate, so as to provide a driving force for the jacking mechanism 54 to realize the up-and-down sliding of the first driving wheel 41 and the second driving wheel 42, thereby realizing the alignment of the driven wheel 431 with the first driving wheel 41 or the second driving wheel 42. When the second driving member 51 drives the driven wheel 431 to slide along the second direction Y towards the first driving wheel 41 and the second driving wheel 42, the first rack 531 drives the third transmission wheel 532 to rotate. The third transmission wheel 532 drives the first ratchet wheel 534 to rotate. The ratchet teeth of the first ratchet wheel 534 slide along the extending direction of the ratchet teeth of the second ratchet wheel 535, so that the first ratchet wheel 534 does not drive the second ratchet wheel 535 to rotate. At this time, the second ratchet wheel 535 does not provide a driving force for the jacking mechanism 54, and the positions of the first driving wheel 41 and the second driving wheel 42 do not change, so as to facilitate the driven wheel 431 to approach and mesh with the first driving wheel 41 or the second driving wheel 42 after approaching it.

[0057] The second transmission shaft 536 is arranged along the first direction Z. The second transmission shaft 536 is rotatably connected to a fixing plate, and the fixing plate can be fixed to the cavity wall of the cabinet body 10. The first bevel gear 537 is coaxially connected to the second ratchet wheel 535 through the second transmission shaft 536, so that the second ratchet wheel 535 can drive the first bevel gear 537 to rotate through the second transmission shaft 536. The third transmission shaft 539 is arranged along the second direction Y. The third transmission shaft 539 is rotatably connected to a fixing plate, and the fixing plate can be fixed to the cavity wall of the cabinet body 10. The second bevel gear 538 meshes with the first bevel gear 537, and the second bevel gear 538 is coaxially connected to the third transmission shaft 539, so as to drive the second bevel gear 538 to rotate through the first bevel gear 537, and further drive the third transmission shaft 539 to rotate through the second bevel gear 538.

[0058] In this embodiment, the jacking mechanism 54 includes a cam 542 and a top block 541. The direction of the rotation axis of the cam 542 is parallel to the second direction Y, and the cam 542 is fixed to the third transmission shaft 539 to drive the cam 542 to rotate through the third transmission shaft 539. The top block 541 is connected to the outer peripheral surface of the first bushing 45. Along the radial direction of the cam 542, convex portions 5421 and concave portions 5422 are respectively provided on the opposite sides of the cam 542, that is, the included angle between the convex portion 5421 and the concave portion 5422 is 180°. When the first driving wheel 41 meshes with the driven wheel 431, the convex portion 5421 abuts against the top block 541. When the second driving wheel 42 meshes with the driven wheel 431, the concave portion 5422 abuts against the top block 541.

[0059] The cam 542 is generally a cylindrical structure. Along the radial direction of the cam 542, the convex portion 5421 protrudes outward from the outer peripheral surface of the cam 542, and the concave portion 5422 is recessed inward from the outer peripheral surface of the cam 542. Along the first direction Z, the top block 541 is located above the cam 542, and a resisting portion 5411 protrudes from one end of the top block 541 close to the cam 542. The resisting portion 5411 can be accommodated in the concave portion 5422.

[0060] It should be noted that the sum of the protruding length of the convex portion 5421 and the recessed depth of the concave portion 5422 can be set based on the distance between the first driving wheel 41 and the second driving wheel 42, so as to realize the switching between the first driving wheel 41 and the second driving wheel 42 by rotating the cam 542 by 180°.

[0061] Thus, in the initial state, taking the driven wheel 431 meshing with the first driving wheel 41 and the convex portion 5421 abutting against the resisting portion 5411 as an example. When it is necessary to make the driven wheel 431 mesh with the second driving wheel 42, the second driving member 51 drives the driven wheel 431 to move toward the side away from the first driving wheel 41, and the second driving member 51 drives the cam 542 to rotate 180° until the concave portion 5422 abuts against the resisting portion 5411. During this process, the first bushing 45, the second bushing 46, the first driving wheel 41, the second driving wheel 42, and the third driving wheel 47 descend under their own gravity, and the second driving wheel 42 just descends to the same height as the driven wheel 431. Subsequently, the second driving member 51 drives the driven wheel 431 to move toward the side close to the second driving wheel 42 until the driven wheel 431 meshes with the second driving wheel 42. During this process, based on the one-way transmission principle of the first ratchet wheel 534 and the second ratchet wheel 535, the cam 542 will not rotate, thus ensuring that the position of the second driving wheel 42 will not change.

[0062] In addition, when the lifting plate 20 does not need to perform a lifting action, the second driving member 51 drives the driven wheel 431 to move away from the first driving wheel 41, and the second driving member 51 drives the cam 542 to rotate 90° until the abutting portion 5411 abuts against the outer peripheral surface of the region outside the convex portion 5421 and the concave portion 5422 of the cam 542. During this process, the first bushing 45, the second bushing 46, the first driving wheel 41, the second driving wheel 42, and the third driving wheel 47 descend under their own gravity, and the second driving wheel 42 and the first driving wheel 41 descend to a position where the driven wheel 431 is in the space between the first driving wheel 41 and the second driving wheel 42, that is, the driven wheel 431 does not mesh with the first driving wheel 41 and the second driving wheel 42, and even if the driving shaft 32 rotates, the lifting plate 20 will not be driven to lift or lower.

However, those of ordinary skill in the art can understand that various changes and substitutions can be made to the specific embodiments of the present application without departing from the scope of the present application. These changes and substitutions all fall within the scope defined by the present application.
