[0029] The specific implementation methods of the present application are further described in detail below with reference to the accompanying drawings.

[0030] like Figures 1 to 4 As shown, this embodiment provides a switch cabinet structure 100 , which can be used for switch cabinets of other types such as low-voltage switch cabinets.

[0031] For the convenience of subsequent reading, the present application introduces a first direction Z, a second direction Y, and a third direction X to describe the embodiments of the present application. The first direction Z, the second direction Y, and the third direction X may be three non-parallel linear directions in space; further, the first direction Z, the second direction Y, 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 Z is the Z-axis direction of the coordinate axis of the three-dimensional coordinate system, the second direction Y is the Y-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.

[0032] The cabinet structure 100 of the switch cabinet includes a cabinet 10, a plurality of drawer assemblies 20, and a lifting assembly 30. Along the second direction Y, a mounting cavity 11 is provided on one side of the cabinet 10. A plurality of support plates 15 are provided in the mounting cavity 11. Along the second direction Y, one end of the support plate 15 is located in the mounting cavity 11 and connected to the cabinet 10, and the other end of the support plate 15 is exposed from the mounting cavity 11. Along the first direction Z, the plurality of support plates 15 are sequentially spaced so that a space for placing the drawer assembly 20 can be formed between any two adjacent support plates 15.

[0033] A plurality of drawer assemblies 20 are arranged corresponding to a plurality of support plates 15, and a drawer assembly 20 can be placed on each support plate 15. The drawer assembly 20 includes a drawer unit 21 and a lifting protrusion 22, and a cavity is provided in the drawer unit 21 to install electronic components. The lifting protrusion 22 is connected to the outer peripheral surface of the drawer unit 21, and is at least partially located in the installation cavity 11, and the lifting protrusion 22 is slidably connected to the cabinet 10 along the first direction Z. Another part of the lifting protrusion 22 is located outside the installation cavity 11, and can be supported by the lifting assembly 30 to drive the drawer unit 21 to rise and fall through the lifting protrusion 22. The support plate 15 is used to support the drawer unit 21, and the drawer unit 21 can slide relative to the support plate 15 along the second direction Y, so as to facilitate the drawer unit 21 to be pulled out of the cabinet 10.

[0034] Along the third direction X, the lifting assembly 30 is arranged on at least one side of the cabinet 10, and the lifting assembly 30 includes a lifting mechanism 31 and a plurality of supporting mechanisms 32. The plurality of supporting mechanisms 32 are arranged corresponding to the plurality of supporting plates 15, and the lifting mechanism 31 is transmission-connected to the plurality of supporting mechanisms 32 to drive the plurality of supporting mechanisms 32 to move along the first direction Z. Among them, the supporting mechanism 32 includes a box body 321, a push-out module 322, a retracting module 323 and a sliding member 324. The box body 321 is transmission-connected to the lifting mechanism 31 to drive the box body 321 to move along the first direction Z through the lifting mechanism 31. Along the third direction X, the sliding member 324 is slidably connected to the box body 321. A slide groove 151 is provided on one side of the support plate 15 close to the slide member 324. The slide groove 151 extends toward one side of the drawer unit 21 along the first direction Z to penetrate the support plate 15, so that the slide member 324 inserted into the slide groove 151 can abut against the lifting protrusion 22 when moving upward with the lifting mechanism 31, thereby driving the drawer unit 21 to move along the first direction Z. The push-out module 322 is configured to drive the slide member 324 to enter the slide groove 151, and the retracting module 323 is configured to drive the slide member 324 to leave the slide groove 151.

[0035] In this way, in the cabinet structure 100 of the switch cabinet of the present application, the lifting mechanism 31 can drive multiple support mechanisms 32 to move synchronously along the first direction Z, and then drive the corresponding drawer units 21 to move along the first direction Z through the multiple support mechanisms 32, thereby lifting the drawer unit 21 from the support plate 15, which not only facilitates the heat dissipation of the bottom of the drawer unit 21, but also can clean it in time when the cabinet structure 100 of the switch cabinet is in a humid environment and causes a lot of water stains to accumulate on the support plate 15 or the drawer unit 21, thereby avoiding short circuit of the circuit in the cabinet 10.

[0036] Please combine again Figures 1 to 3 In one embodiment, the cabinet 10 is a substantially square structure. Along the second direction Y, the installation cavity 11 is provided on one side of the cabinet 10, and a drawer opening 12 is provided on the other side of the cabinet 10, the drawer opening 12 being connected to the installation cavity 11. The number of the drawer openings 12 is the same as that of the support plate 15, and the positions of the drawer openings 12 correspond to those of the support plate 15, so that the drawer unit 21 placed on the support plate 15 can leave the installation cavity 11 from the drawer openings 12.

[0037] The lifting protrusion 22 is roughly a "U"-shaped structure and is wrapped around the outer circumference of the drawer unit 21. The lifting protrusion 22 can be connected to the drawer unit 21 by welding or threaded connection. The bottom end surface of the lifting protrusion 22 is coplanar with the bottom end surface of the drawer unit 21, so that the sliding member 324 can abut against the bottom end surface of the lifting protrusion 22 after extending into the slide groove 151. Along the third direction X, the opposite sides of the lifting protrusion 22 are slidably matched with the cabinet 10. For example, along the third direction X, the opposite sides of the lifting protrusion 22 are convexly provided with sliding protrusions, and the inner walls of the mounting cavity 11 on the adjacent sides are provided with guide grooves, and the sliding protrusions can be slidably arranged in the guide grooves to guide the lifting protrusion 22 to slide along the first direction Z.

[0038] Along the second direction Y, one end of the lifting protrusion 22 away from the drawing opening 12 extends to the outside of the installation cavity 11, and the end of the lifting protrusion 22 located outside the installation cavity 11 is provided with extensions 220 on opposite sides of the third direction X. The extension direction of the extension 220 is parallel to the third direction X, and one end of the extension 220 away from the lifting protrusion 22 extends toward one side of the sliding member 324, and extends to the lifting path of the extended sliding member 324, so that the sliding member 324 can resist the extension 220 during the upward movement and drive it to move synchronously.

[0039] Please combine again Figures 2 to 4 In one embodiment, the cabinet structure 100 of the switch cabinet further includes a plurality of switching components 40. Along the third direction X, the plurality of switching components 40 are arranged on one side of the cabinet 10 close to the lifting component 30, and the plurality of switching components 40 are arranged corresponding to the plurality of supporting mechanisms 32. Along the first direction Z, the plurality of switching components 40 are arranged in sequence and spaced apart.

[0040] In this embodiment, the number of lifting assemblies 30 is set to two. Along the third direction X, the two lifting assemblies 30 are arranged at intervals on opposite sides of the cabinet 10. Correspondingly, the number of switching assemblies 40 is twice that of the supporting mechanism 32, and the switching assemblies 40 are divided into two groups. One group of switching assemblies 40 is located on one side of the cabinet 10 along the third direction X, and the other group of switching assemblies 40 is located on the other side of the cabinet 10 along the third direction X. The number of each group of switching assemblies 40 is the same as the number of the supporting mechanism 32, and each switching assembly 40 in each group of switching assemblies 40 is arranged in a one-to-one correspondence with the supporting mechanism 32.

[0041] The switching assembly 40 includes a rotating member 41, which is rotatably connected to the cabinet 10. The switching assembly 40 also includes a rotating shaft 42, the axis of which is parallel to the third direction X, one end of which is rotatably connected to a side of the cabinet 10 close to the lifting assembly 30, and the rotating member 41 is connected to the other end of the rotating shaft 42.

[0042] The rotating member 41 is generally an "L"-shaped structure and includes a first section 411 and a second section 412. The extension direction of the first section 411 is parallel to the radial direction of the rotating shaft 42, and the second section 412 is integrally formed at one end of the first section 411. The middle section of the second section 412 is fixed to the rotating shaft 42.

[0043] The rotating member 41 has a first state and a second state. The first state is set as the first section 411 is at least partially located on the path of the support mechanism 32 moving upward in the first direction Z. When the rotating member 41 is in the first state, the first section 411 can resist the upwardly moving ejection module 322 and provide a first driving force to the ejection module 322. Based on the first driving force, the ejection module 322 drives the sliding member 324 to enter the slide groove 151.

[0044] The second state is set as the second section 412 being at least partially located on the path of the support mechanism 32 moving downward in the first direction Z. When the rotating member 41 is in the second state, the second section 412 can resist the downward moving retraction module 323 and provide a second driving force to the retraction module 323. Based on the second driving force, the retraction module 323 drives the sliding member 324 to leave the slide groove 151.

[0045] It is understandable that the specific shape and size of the rotating member 41 can be adaptively adjusted according to actual design requirements, and it is only necessary to ensure that the rotating member 41 can be rotated to a first state to apply a force to the ejection module 322 and can be rotated to a second state to apply a force to the retraction module 323.

[0046] In other embodiments, the rotating member 41 may also be configured as a "U"-shaped structure and have two second sections 412, the two second sections 412 are respectively connected to the two ends of the first section 411, and the position of the first section 411 to which the rotating shaft 42 is connected may be adaptively designed according to actual design requirements.

[0047] Please combine again Figures 2 to 4 In one embodiment, the cabinet structure 100 of the switch cabinet further includes a driving assembly 50. The driving assembly 50 includes a first driving member, a plurality of transmission wheels 51 and a transmission belt 52. A transmission wheel 51 is sleeved on the outer circumference of each rotating shaft 42, and the transmission wheel 51 is coaxially fixed on the rotating shaft 42 to drive the rotating shaft 42 to rotate through the transmission wheel 51. The plurality of transmission wheels 51 are transmission-connected through the transmission belt 52, and the first driving member is transmission-connected to any one of the transmission wheels 51. The first driving member is a power device such as a rotary motor, and the first driving member drives each rotating member 41 installed on the same side of the cabinet 10 to rotate through the transmission wheel 51 and the transmission belt 52.

[0048] It is understandable that in other embodiments, the transmission wheels 51 on both sides of the cabinet 10 share the same first driving member to reduce costs. For example, a transmission wheel 51 on one side where the first driving member is located is coaxially connected to a transmission wheel 51 on the other side through a shaft.

[0049] Please combine again Figures 4 to 6 In one embodiment, the ejection module 322 includes a first wedge 3221 and a second wedge 3222. The first wedge 3221 is slidably connected to the box body 321 along the first direction Z, and the second wedge 3222 is slidably connected to the box body 321 along the third direction X, and the second wedge 3222 is connected to the sliding member 324.

[0050] The box body 321 is generally a square structure. Along the first direction Z, a first sliding groove 3211 is provided on the top surface of the box body 321. The first sliding groove 3211 extends along the first direction Z and penetrates the box body 321. Along the third direction X, a second sliding groove 3212 is provided on the side of the box body 321 close to the cabinet 10. The second sliding groove 3212 extends along the third direction X and does not penetrate the box body 321. The first wedge 3221 is penetrated in the first sliding groove 3211 and slidably cooperates with the first sliding groove 3211. The extension length of the first wedge 3221 is greater than that of the first sliding groove 3211. The second wedge 3222 is slidably provided in the second sliding groove 3212, and the extension length of the second wedge 3222 is less than that of the second sliding groove 3212, so as to ensure that the second wedge 3222 and the sliding member 324 connected to the second wedge 3222 can be completely accommodated in the first sliding groove 3211.

[0051] The second sliding groove 3212 is connected to the first sliding groove 3211 , and the position where the second sliding groove 3212 is connected to the first sliding groove 3211 is approximately located in the middle section of the second sliding groove 3212 , so that the first wedge 3221 and the second wedge 3222 can act on each other.

[0052] A first inclined surface P1 is provided at the bottom end of the first wedge 3221 on the side close to the cabinet 10, and the first inclined surface P1 extends obliquely from the bottom end thereof toward the side close to the cabinet 10 along the first direction Z. A second inclined surface P2 is provided at the top of the end of the second wedge 3222 away from the cabinet 10. The first inclined surface P1 is arranged parallel to the second inclined surface P2, and the first inclined surface P1 and the second inclined surface P2 abut against each other, so that the first wedge 3221 cooperates with the second wedge 3222 to form a wedge mechanism.

[0053] When the rotating member 41 is in the first state, the lifting mechanism 31 can drive the box body 321 to move upward so that the top of the first wedge member 3221 is supported by the first section 411, so as to provide a first driving force to the first wedge member 3221 through the first section 411. Based on the first driving force, the first wedge member 3221 can drive the sliding member 324 to enter the sliding groove 151 by pushing the second wedge member 3222.

[0054] In this embodiment, the retracting module 323 includes an elastic member 3230. The elastic member 3230 is arranged along the third direction X, one end of the elastic member 3230 is elastically connected to the second wedge member 3222, and the other end of the elastic member 3230 is elastically connected to the bottom wall of the second sliding groove 3212. The elastic member 3230 is a tension spring, and the elastic member 3230 is configured to provide a second driving force to the second wedge member 3222. Based on the second driving force, the second wedge member 3222 drives the sliding member 324 to leave the sliding groove 151.

[0055] When the sliding member 324 extends into the slide groove 151 , the portion of the first wedge member 3221 having the first inclined surface P1 is located below the second wedge member 3222 along the first direction Z to limit the second wedge member 3222 from being driven by the elastic member 3230 to reset, thereby preventing the sliding member 324 from leaving the slide groove 151 .

[0056] In particular, the first wedge-shaped member 3221 is provided with a first elastic protrusion 32210 on the outer circumference of the portion where the first inclined surface P1 is not provided. The second elastic protrusion 32110 is provided on the inner circumference of the first sliding groove 3211. Along the first direction Z, the second elastic protrusion 32110 is located above the second sliding groove 3212, and the second elastic protrusion 32110 and the first elastic protrusion 32210 abut against each other in the first direction Z, so that the first wedge-shaped member 3221 is restricted from sliding downward under the action of gravity by the second elastic protrusion 32110 abutting against the first elastic protrusion 32210. When the sliding member 324 is located in the second sliding groove 3212, the elastic member 3230 is in a natural state, and under the limiting action of the second elastic protrusion 32110 on the first elastic protrusion 32210, the first inclined surface P1 of the first wedge 3221 is in contact with the second inclined surface P2 of the second wedge 3222, so that the first wedge 3221 can overcome the abutment of the second elastic protrusion 32110 and move downward by the rotating member 41, thereby driving the second wedge 3222 to slide and push the sliding member 324 into the sliding groove 151. In addition, when the sliding member 324 is located in the second sliding groove 3212 and the elastic member 3230 is in a natural state, the lifting mechanism 31 can smoothly drive the box body 321 to move upward along the first direction Z to the opening of the sliding groove 151.

[0057] It is worth noting that, along the first direction Z, the depth of the sliding groove 151 needs to be greater than the thickness of the sliding member 324 .

[0058] In this way, when the first wedge 3221 is rotated to be pressed against by the rotating member 41 above it and moves downward along the first direction Z, the first wedge 3221 can push the second wedge 3222 to slide along the third direction X toward one side of the cabinet 10, so that the second wedge 3222 drives the sliding member 324 to slide into the chute 151. In this process, the elastic member 3230 is continuously stretched. In addition, after the sliding member 324 enters the chute 151, the portion of the first wedge 3221 provided with the first inclined surface P1 moves downward to the outside of the box body 321, so that the portion of the first wedge 3221 not provided with the first inclined surface P1 presses against the second wedge 3222, thereby preventing the second wedge 3222 from being reset under the action of the elastic member 3230 and driving the sliding member 324 to leave the chute 151, and also facilitates the subsequent pressing of the bottom end of the first wedge 3221 by the rotating member 41 to push the first wedge 3221 upward. After the sliding member 324 enters the sliding groove 151, the lifting mechanism 31 continues to drive the box body 321 to move upward, and then drives the drawer unit 21 to move upward through the sliding member 324 supporting the extension part 220, thereby lifting the drawer unit 21, making it convenient to clean the drawer unit 21 and the support plate 15 from the pull-out opening 12, and also helping the drawer unit 21 to quickly dissipate heat by blowing cold air to the bottom of the drawer unit 21.

[0059] When the lifted drawer unit 21 needs to be reset, the rotating member 41 rotates until its second section 412 is located below the box body 321. Subsequently, the lifting mechanism 31 drives the box body 321 to move downward, and the bottom end of the first wedge 3221 abuts against the second section 412, so that the first wedge 3221 moves upward through the second section 412 until the first inclined surface P1 contacts the second inclined surface P2. At this time, the second wedge 3222 moves toward the side away from the cabinet 10 under the action of the elastic member 3230, thereby retracting the sliding member 324 from the sliding groove 151. In this process, the second wedge 3222 pushes the first wedge 3221 to move upward. When the elastic member 3230 returns to its original length, the first wedge 3221 has overcome the limiting effect of the second elastic protrusion 32110 on it and moves upward to pass over the second elastic protrusion 32110.

[0060] Please combine again Figures 5 to 8 , and see Figure 3 In one embodiment, the switch cabinet structure 100 further includes a locking assembly 60. The locking assembly 60 includes a third wedge 61 and a fourth wedge 62.

[0061] The bottom wall of the slide groove 151 is provided with a third slide groove 152, which extends along the third direction X and is connected to the slide groove 151. One end of the third wedge 61 is slidably disposed in the slide groove 151, and the other end thereof is slidably disposed in the third slide groove 152. Along the first direction Z, the thickness of the end of the third wedge 61 close to the sliding member 324 is greater than the thickness of the sliding member 324, so as to ensure that the sliding member 324 always abuts against the third wedge 61 when the sliding member 324 moves upward in the slide groove 151 along the first direction Z. A third inclined surface P3 is provided on the side of the end of the third wedge 61 away from the sliding member 324 away from the drawing port 12.

[0062] Along the second direction Y, a fourth sliding groove 153 is provided on the side of the support plate 15 away from the cabinet 10. The fourth sliding groove 153 extends along the second direction Y, and the fourth sliding groove 153 extends to connect with the third sliding groove 152. The fourth wedge 62 is generally a "U"-shaped structure, and its opening is arranged toward the support plate 15. One end of the fourth wedge 62 is slidably arranged in the fourth sliding groove 153, and the other end of the fourth wedge 62 is located above the lifting protrusion 22 and abuts against the lifting protrusion 22 to limit the upward movement of the lifting protrusion 22 and ensure the stability of the drawer unit 21 when placed on the support plate 15. In addition, a fourth inclined surface P4 is provided at one end of the fourth wedge 62 close to the third wedge 61, and the fourth inclined surface P4 is arranged parallel to the third inclined surface P3 and the two abut against each other, so that the third wedge 61 and the fourth wedge 62 constitute an inclined wedge mechanism.

[0063] In this way, when the sliding member 324 extends into the sliding groove 151, the sliding member 324 abuts against the third wedge member 61 and pushes the third wedge member 61 to slide along the third direction X, and the third wedge member 61 abuts against the fourth wedge member 62, thereby pushing the fourth wedge member 62 to slide along the second direction Y, so that the fourth wedge member 62 moves toward the side away from the support plate 15, and then the area of ​​the fourth wedge member 62 located above the lifting protrusion 22 moves along the second direction Y until it no longer abuts against the lifting protrusion 22, thereby releasing the fourth wedge member 62 from limiting the lifting protrusion 22. At this time, the sliding member 324 can support the lifting protrusion 22 to move upward, thereby driving the drawer unit 21 to move upward.

[0064] Furthermore, the locking assembly 60 further includes a compression spring 63, which is located in the fourth sliding groove 153 and sleeved on the outer periphery of the portion of the fourth wedge member 62 located in the fourth sliding groove 153. The compression spring 63 abuts against the fourth wedge member 62 and provides an elastic force for the fourth wedge member 62 to move toward the third wedge member 61. For example, one end of the compression spring 63 abuts against a protruding structure provided on the groove wall of the fourth sliding groove 153, and the other end thereof abuts against a protruding structure provided on the fourth wedge member 62.

[0065] Thus, when the third wedge 61 pushes the fourth wedge 62 to move toward the side away from the support plate 15, the compression spring 63 is continuously compressed. When the sliding member 324 leaves the slide groove 151, the sliding member 324 no longer abuts against the third wedge 61, and the compression spring 63 pushes the fourth wedge 62 to slide toward the side close to the support plate 15 and continues to abut against the lifting protrusion 22, and the third wedge 61 is pushed back by the fourth wedge 62, so that the sliding member 324 can abut against the third wedge 61 when it enters the slide groove 151 again.

[0066] Please combine again Fig. 9 , and see Figure 1 and Figure 2 In one embodiment, the number of cabinets 10 is set to be multiple, and along the third direction X, the multiple cabinets 10 are arranged in sequence and spaced apart, and a lifting assembly 30 is provided between any two adjacent cabinets 10. In addition, along the third direction X, a lifting assembly 30 is also provided on the opposite sides of the cabinets 10 located on both sides.

[0067] Among them, the multiple supporting mechanisms 32 in the same lifting assembly 30 can rotate relative to the lifting mechanism 31, so that the multiple supporting mechanisms 32 in the same lifting assembly 30 can cooperate with any adjacent cabinet 10. In this way, when a cabinet 10 completes the cleaning or cooling operation, and another cabinet 10 adjacent to the cabinet 10 also needs to be cleaned or cooled, the multiple supporting mechanisms 32 in the lifting assembly 30 between the two cabinets 10 rotate 180° synchronously, so that the lifting assembly 30 serves the current cabinet 10, and a group of lifting assemblies 30 can serve at least two cabinets 10 at the same time, which greatly reduces the production cost.

[0068] In this embodiment, the cabinet structure 100 of the switch cabinet further includes a sealing cabinet 13 and a sealing plate 14. Along the second direction Y, the sealing cabinet 13 is connected to the side of the plurality of cabinets 10 away from the drawer opening 12, and the installation cavity 11 is sealed by the sealing cabinet 13, and the lifting assembly 30 is protected therein. The sealing plate 14 is connected to the cabinet 10 and the sealing cabinet 13, so as to seal the space between any two adjacent cabinets 10.

[0069] In this embodiment, the lifting mechanism 31 includes a second driving member 311, a lead screw 312, a threaded sleeve 313 and a rotating sleeve 314. The lead screw 312 is arranged along the first direction Z, and the two ends of the lead screw 312 are rotatably connected to the sealing cabinet 13. The second driving member 311 is a power device such as a motor, and the driving end of the second driving member 311 is connected to the lead screw 312 to drive the lead screw 312 to rotate. The threaded sleeve 313 is sleeved on the outer periphery of the lead screw 312 and is threadedly matched with the lead screw 312 to drive the threaded sleeve 313 to move along the first direction Z through the rotation of the lead screw 312. The rotating sleeve 314 is sleeved on the outer periphery of the threaded sleeve 313, and the rotating sleeve 314 can rotate relative to the threaded sleeve 313. The box bodies 321 of the multiple supporting mechanisms 32 are all connected to the rotating sleeve 314, so that the multiple box bodies 321 are driven to rotate 180° through the rotating sleeve 314. The rotating sleeve 314 can be driven to rotate by a motor, or one end of the rotating sleeve 314 can be extended out of the cabinet 10 and the rotating sleeve 314 can be rotated manually.

[0070] It is understandable that in other embodiments, the number of support mechanisms 32 of the same lifting assembly 30 is twice the number of support plates 15 of an adjacent cabinet 10. In addition, along the first direction Z, two support mechanisms 32 are provided at the same height of the same lifting assembly 30, and the two support mechanisms 32 are arranged back to back, so that the two support mechanisms 32 at the same height can be simultaneously matched with two adjacent cabinets 10.

[0071] Please combine again Figure 2 and Figure 5 In one embodiment, the cabinet structure 100 of the switch cabinet further includes an air circulation assembly 70. When the slide member 324 supports the drawer unit 21 to move toward a side away from the support plate 15, the air circulation assembly 70 is configured to deliver low-temperature gas to the space between the drawer unit 21 and the support plate 15. The air circulation assembly 70 may be composed of an air pump and an air blowing pipe, the air blowing pipe having a plurality of air outlet ends, each of which corresponds to a drawer unit 21, so that after each drawer unit 21 of the same cabinet 10 moves, the air blowing pipe simultaneously blows gas to the bottom of each drawer unit 21 to quickly cool the drawer unit 21.

[0072] In addition, the gas circulation component 70 may also be provided with a condensation tower or other device to cool the blown gas.

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.
