[0036] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0040] Reference Figures 1 to 4 As shown, this embodiment provides a control cabinet, which includes a housing 100, a support 200, and a drive unit 300.

[0041] Specifically, the outer casing 100 has first through holes 101 on both sides along the first horizontal direction; two support members 200 are provided, each corresponding to one of the first through holes 101, and the support members 200 are slidably connected to the outer casing 100, each support member 200 including a door panel portion 210; a drive member 300 is connected to both support members 200, and the drive member 300 is used to drive the two support members 200 to slide relative to the outer casing 100 in opposite directions along the first horizontal direction. The first horizontal direction can be the length direction of the control cabinet.

[0042] The support member 200 has a first position and a second position that slide relative to the outer shell 100. When the support member 200 is in the first position, the door panel portion 210 is located inside the first through hole 101 and forms a seal with the first through hole 101. When the support member 200 is in the second position, the door panel portion 210 is disengaged from the first through hole 101 and is located outside the outer shell 100, that is, the first through hole 101 is open.

[0043] It is understandable that components can be installed on both support members 200, and when the support member 200 is in the first position, the components are located inside the outer shell 100, and the door panel 210 is located inside the first through hole 101 and forms a seal with the first through hole 101, which can protect the components.

[0044] When the control cabinet needs configuration, repair, or maintenance, the support member 200 can be slid to the second position via the drive member 300 to open the first through hole 101. Components can then move with the support member 200 to the outside of the housing 100, or remain inside the housing 100 and close to the first through hole 101. Workers do not need to extend their arms into the housing 100, or only need to extend their arms a short distance through the first through hole 101 to complete the task, effectively improving work efficiency. Furthermore, the two support members 200 facilitate component placement and ensure that the distance the support member 200 extends beyond the first through hole 101 in the second position is appropriate, effectively guaranteeing the stability of the sliding connection between the support member 200 and the housing 100.

[0045] In this embodiment, reference is made to Figure 1 and Figure 2 As shown, the support member 200 also includes a support plate portion 220 connected to the door panel portion 210. The support plate portion 220 is slidably connected to the outer casing 100, and the support plate portions 220 of one of the two support members 200 are spaced apart from the support plate portions 220 of the other in a vertical direction. In this embodiment, components can be mounted on the support plate portions 220, and the support plate portions 220 are spaced apart in a vertical direction, which facilitates the layout of components. The vertical direction can be the height direction of the control cabinet.

[0046] For example, the support member 200 includes at least one support plate portion 220, and preferably, the support member 200 includes one to three support plate portions 220.

[0047] In one feasible implementation, all support plate portions 220 of the two support members 200 except for the lowest support plate portion 220 are provided with ventilation holes 221 so that the space inside the outer casing 100 can be interconnected, and thus have a good heat dissipation effect.

[0048] In one feasible embodiment, the door panel 210 is provided with ventilation holes, and a dustproof net 211 is provided inside the ventilation holes. When the support member 200 is in the first position, air outside the outer casing 100 can enter the outer casing 100 through the dustproof net 211, or air inside the outer casing 100 can be discharged through the dustproof net 211, so that the outer casing 100 has a good heat dissipation effect; and the dustproof net 211 can effectively prevent dust and other substances outside the outer casing 100 from entering the outer casing 100.

[0049] In this embodiment, reference continues to be made to... Figure 1 and Figure 2 As shown, a support column 121 is provided inside the outer casing 100. A threaded sleeve 122 is threadedly connected to the support column 121. The threaded sleeve 122 is correspondingly provided with the support plate portion 220. The support plate portion 220 is provided with an elongated hole 222. The support column 121 passes through the elongated hole 222, and the threaded sleeve 122 abuts against the bottom surface of the corresponding support plate portion 220. Under the support of the corresponding threaded sleeve 122 and the guidance of the elongated hole 222, the support plate portion 220 can achieve stable and reliable sliding of the support member 200 relative to the outer casing 100 in the first horizontal direction. The elongated hole 222 can also limit the sliding range of the support member 200 in the first horizontal direction. Of course, the support plate portion 220 can also be slidably connected to the outer casing 100 through a slide rail slider structure, or by providing a guide rail groove or other structure on the outer casing 100. This embodiment does not limit this.

[0050] For example, the support column 121 is fixed to the bottom inside the housing 100 and extends vertically.

[0051] For example, the driving component 300 can be configured as a telescopic driving component 300, a motor or other driving structure, and this embodiment does not limit it.

[0052] Specifically, taking the drive component 300 as a telescopic drive component 300 as an example, the control cabinet also includes two connecting rods 410. The drive component 300 includes a cylinder body and two telescopic rods slidably connected to the cylinder body. The cylinder body is fixed inside the outer shell 100. The two telescopic rods, the two connecting rods 410, and the two support members 200 are arranged in a one-to-one correspondence. The first end of the connecting rod 410 is hinged to the corresponding support member 200, and the second end of the connecting rod 410 is hinged to the corresponding telescopic rod. The first end of the connecting rod 410 can be hinged to the connecting seat 230 via a first shaft. In this embodiment, when the telescopic rod extends outward from the cylinder body, the connecting rod 410 can drive the support member 200 to slide towards the second position; when the telescopic rod retracts into the cylinder body, the connecting rod 410 can drive the support member 200 to slide towards the first position. The transmission is stable and reliable, effectively preventing jamming.

[0053] For example, the telescopic drive 300 includes, but is not limited to, an electric push rod or a cylinder.

[0054] For example, the support member 200 is provided with a connecting seat 230, and the support member 200 is hinged to the corresponding connecting rod 410 through the connecting seat 230. The connecting seat 230 can be a U-shaped structure, that is, the first end of the connecting rod 410 is located between two opposite side plates of the connecting seat 230.

[0055] For example, a fixing seat 130 is provided at the bottom inside the housing 100, and the cylinder is fixed on the fixing seat 130.

[0056] In one feasible embodiment, the telescopic rod is connected to a sliding seat 420, which is hinged to the second end of the corresponding connecting rod 410. The sliding seat 420 is also slidably connected to the housing 100. This balances the force on the driving component 300, ensuring that the force exerted by the sliding seat 420 on the telescopic rod is in the same direction as the telescopic rod's extension and retraction, effectively extending the service life of the telescopic rod. The telescopic rod is hinged to the sliding seat 420. Exemplarily, the telescopic rod, the sliding seat 420, and the connecting rod can be hinged together via a second shaft.

[0057] For example, the slide seat 420 can be a U-shaped structure, that is, the second end of the connecting rod 410 is located between two opposite side plates of the slide seat 420.

[0058] For example, the sliding seat 420 can be slidably connected to the housing 100 by means of a slide rail slider structure, or by a guide rail groove or other structure provided on the housing 100. This embodiment does not limit the scope of the invention.

[0059] For example, taking the drive member 300 as a telescopic drive member 300, two drive members 300 can be arranged side by side. Of course, the number of drive members 300 can also be other than that specified in this embodiment.

[0060] In this embodiment, reference is made to Figure 3 and Figure 4 As shown, the outer casing 100 includes a cabinet 111 and two sealing plates 112. The cabinet 111 has first through holes 101 on both sides along a first horizontal direction, and second through holes 102 on both sides along a second horizontal direction. The sealing plates 112 are correspondingly positioned to cover the corresponding second through holes 102. The sealing plates 112 are detachably placed over the corresponding second through holes 102, protecting the components inside the outer casing 100. Removing the sealing plates 112 from the cabinet 111 facilitates the configuration, repair, and maintenance of the control cabinet, and also makes cleaning inside the outer casing 100 easier. The second horizontal direction can be the width direction of the control cabinet.

[0061] Exemplarily, the housing 100 further includes a fastener 113, which passes through the sealing plate 112 and connects to the housing 100 to enable the sealing plate 112 to be detached from the housing 100. The fastener 113 includes, but is not limited to, bolts. Multiple fasteners 113 are provided; for example, when the sealing plate 112 is a rectangular plate, four fasteners 113 are provided and located at the four corners of the sealing plate 112.

[0062] In this embodiment, reference is made to Figure 1 , Figures 3 to 5 As shown, the top of the outer casing 100 is provided with an exhaust vent 103. The control cabinet also includes a protective frame 500 and a negative pressure fan 600. The protective frame 500 includes a frame body 510 and a cylindrical part 520 connected to the frame body 510. The frame body 510 is located inside the outer casing 100, and the cylindrical part 520 is inserted into the exhaust vent 103. The exhaust port of the negative pressure fan 600 is connected to the cylindrical part 520. When the negative pressure fan 600 is started, low-temperature air enters the outer casing 100 through the dustproof net 211, and high-temperature gas inside the outer casing 100 is drawn out by the negative pressure fan 600 through the cylindrical part 520 of the frame body 510, achieving convection ventilation to achieve heat dissipation, which is stable and reliable.

[0063] It is understandable that the protective frame 500 is fixed inside the outer shell 100 by the frame body 510, and the connection is stable and reliable, and a seal is formed between the cylindrical part 520 of the protective frame 500 and the exhaust hole 103.

[0064] In one feasible embodiment, the control cabinet further includes an exhaust pipe 700, which includes a main pipe 710 and multiple branch pipes 720 communicating with the main pipe 710. The main pipe 710 is connected to the cylindrical portion 520 of the protective frame 500. Multiple negative pressure fans 600 are provided, each corresponding to one of the branch pipes 720, and the exhaust port of the negative pressure fan 600 is connected to the corresponding branch pipe 720. In this embodiment, the arrangement of multiple negative pressure fans 600 can effectively enhance airflow within the outer casing 100, thus facilitating heat dissipation.

[0065] For example, the top of the housing 100 is provided with a support base 140, and the negative pressure fan 600 is fixed on the support base 140, with a stable and reliable connection. The support base 140 and the negative pressure fan 600 are arranged in a one-to-one correspondence.

[0066] For example, the negative pressure fan 600 has two to six.

[0067] In one feasible implementation, multiple negative pressure fans 600 are electrically connected to the same controller, meaning the controller can control multiple negative pressure fans 600 to operate synchronously.

[0068] In one feasible implementation, a waterproof and breathable membrane (not shown) is provided inside the cylinder 520. The waterproof and breathable membrane can prevent moisture from entering the interior of the negative pressure fan 600 without affecting ventilation, thus effectively ensuring the air extraction efficiency and service life of the negative pressure fan 600.

[0069] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
