[0040] To improve the ease of maintenance of electrical components 10 and reduce the possibility of misoperation during maintenance, this technical solution proposes an electrical box, including:

[0041] The housing 100 has a receiving cavity 110 with an opening on one side;

[0042] The sliding assembly 200 is disposed in the receiving cavity 110. The sliding assembly 200 has a fixed part 210 and a sliding part 220. The fixed part 210 is connected to the housing 100. The sliding part 220 is slidably connected to the fixed part 210 to move toward or away from the opening. The sliding part 220 is used to connect the electrical component 10.

[0043] The drive assembly 300 is disposed on the fixed part 210 and is drivenly connected to the sliding part 220.

[0044] In the technical solution of this utility model, by providing a sliding component 200 in the accommodating cavity 110 of the housing 100, the electrical component 10 can slide into or out of the accommodating cavity 110. When maintenance of the electrical component 10 is required, it is only necessary to slide the electrical component 10 out of the accommodating cavity 110. This increases the space for maintenance operations, facilitates maintenance, and also helps to reduce the risk of misoperation. In addition, by driving the sliding part 220 to slide through the driving component 300, the position adjustment of the electrical component 10 is also facilitated, which helps to further improve the convenience of maintenance.

[0045] like Figures 1 to 7 In one embodiment of this utility model, the electrical box includes a box body 100, which has a receiving cavity 110 with an opening on one side. A sliding assembly 200 is provided in the receiving cavity 110. The sliding assembly 200 has a fixed part 210 and a sliding part 220. The sliding part 220 can slide relative to the fixed part 210. The sliding assembly 200 can adopt the form of sliding cooperation between a slide rail and a slider. The fixed part 210 is connected to the inner wall of the receiving cavity 110. The sliding part 220 can slide towards the opening side, sliding into or out of the receiving cavity 110. The electrical component 10 can be fixed on the sliding part 220 by a detachable connection. In this way, when it is necessary to repair the electrical component 10, it is only necessary to slide the sliding part 220 to slide the electrical component 10 out of the receiving cavity 110. Since there is a larger operating space outside the receiving cavity 110, it is more convenient to repair the electrical component 10, which helps to reduce the difficulty of maintenance and also reduces the risk of misoperation. Figure 5 and Figure 6One structural form of the sliding assembly 200 is shown. In this design, the fixing part 210 is generally a long strip-shaped plate structure. Slide grooves are recessed on two opposite sidewalls of the fixing part 210 along its width direction, extending along its length. The sliding part 220 is generally a square structure. Two hooks protrude in the same direction on two opposite sidewalls of the sliding part 220. Each hook is embedded in a slide groove and slides in cooperation with it. Thus, the fixing part 210 and the sliding part 220 are connected together through the cooperation of the two hooks and the two slide grooves, allowing the sliding part 220 to slide along the extension direction of the slide groove. Furthermore, in this design, the electrical box also includes a drive assembly 300. The drive assembly 300 is mounted on the fixing part 210 and can drive the sliding part 220 to move. The drive assembly 300 can be a device such as an electric actuator. Driving the sliding part 220 into and out of the receiving cavity 110 via the drive assembly 300 saves manpower and further facilitates maintenance.

[0046] like Figure 2 In another embodiment of this utility model, the electrical box further includes a partition 400, which can be a flat plate structure. At least one partition 400 can be provided. The partition 400 is connected to the inner wall of the accommodating cavity 110 and divides the accommodating cavity 110 into multiple independent accommodating spaces. At least one sliding component 200 can be placed in each accommodating space, and each sliding component 200 is provided with a corresponding driving component 300. An electrical element 10 is provided on the sliding part 220 of each sliding component 200. In this embodiment, each electrical element 10 can be an independent circuit that can realize one or more functions. The modules, in which the various electrical components 10 are connected by wires to form a complete system, and the multiple sliding components 200 can be spaced apart, which reduces mutual interference between the various electrical components 10 in the system. Thus, when maintenance is required, each electrical component 10 can slide out of the housing 110 individually, and the operator can perform individual maintenance on each electrical component 10, improving the flexibility and convenience of maintenance. In addition, in this design, the partition 400 can be densely covered with mesh holes, which facilitates heat dissipation. When cooling fans and other devices are installed on the electrical box, it also helps to ensure ventilation and heat dissipation efficiency.

[0047] like Figure 1In one embodiment of this utility model, the electrical box further includes indicator lights 500, which are disposed on the box body 100. Each electrical component 10 is electrically connected to at least one indicator light 500. In this solution, multiple indicator lights 500 are provided, which are arranged in a matrix on the top of the box body 100 on the side away from the ground. Each indicator light 500 can be electrically connected to one electrical component 10. The indicator light 500 can indicate the working status of the electrical component 10 connected to it. In this way, the staff can determine which electrical component 10 has failed based on the status of the indicator light 500, which facilitates the location of the fault and further improves the convenience of maintaining the electrical component 10.

[0048] like Figure 4 and Figure 5 This utility model provides an embodiment of a drive assembly 300. In this embodiment, the drive assembly 300 includes: a lead screw 310, which is rotatably disposed on the fixed part 210 and extends along the sliding direction of the sliding part 220; a transmission member 320, which is connected to the sliding part 220 and threadedly engaged with the lead screw 310; and an actuator 330, which is connected to the lead screw 310 to drive the lead screw 310 to rotate. The two ends of the lead screw 310 are rotatably connected to the fixed part 210 via bearings. To reduce the size, a cavity with a top opening can be formed in the fixed part 210, and the lead screw 310 is rotatably mounted in the cavity. In addition, the lead screw 310 extends in the direction toward the opening of the receiving cavity 110. A transmission member 320 is also provided in the cavity of the fixed part 210. The transmission member 320 can be a square block structure. The transmission member 320 slides against the inner wall of the cavity and slides along the length of the lead screw 310. A threaded hole can be provided on the transmission member 320. The lead screw 310 passes through the threaded hole and is threaded into the threaded hole. When the lead screw 310 rotates, the lead screw 310 can rotate through the threaded hole. The drive transmission component 320 slides along the length direction of the lead screw 310. In addition, the sliding part 220 is connected to the transmission component 320. In this way, the transmission component 320 can drive the sliding part 220 to move along the length direction of the lead screw 310, thereby driving the sliding part 220. In addition, in order to facilitate the rotation of the lead screw 310, in this solution, one end of the lead screw 310 passes through the side wall opposite the opening in the accommodating cavity 110 and extends to the outside of the housing 100. The drive assembly 300 also includes an actuator 330, which can be in the form of a motor or a handle. The actuator 330 is connected to the lead screw 310 and drives the lead screw 310 to rotate through the actuator 330.

[0049] In one embodiment of this utility model, the sliding part 220 is detachably connected to the electrical component 10. For example, the sliding part 220 and the electrical component 10 can be fixed by screwing or snapping. This facilitates the disassembly and assembly of the electrical component 10 during later maintenance, which helps to further improve the convenience and efficiency of maintenance.

[0050] like Figure 6 and Figure 7 This utility model provides an embodiment of a detachable connection between the sliding part 220 and the electrical component 10. In this solution, one of the sliding part 220 and the electrical component 10 is provided with a limiting groove 610, and the other of the sliding part 220 and the electrical component 10 is provided with a limiting body 620, which is inserted into the limiting groove 610. The limiting groove 610 can be provided at the top of the sliding part 220 and can be of any shape. The limiting body 620 is provided at the bottom of the electrical component 10 and protrudes from the electrical component. The shape and size of the limiting body 620 of component 10 are adapted to the limiting groove 610. During assembly, the electrical component 10 can be placed on the sliding part 220, and the limiting body 620 can be inserted into the limiting groove 610. At this time, the limiting groove 610 limits the limiting body 620, restricting the movement of the electrical component 10 relative to the sliding part 220 in the radial direction of the limiting groove 610, thus ensuring the stability of the electrical component 10 after installation. Of course, the setting positions of the limiting groove 610 and the limiting body 620 can be interchanged, which can also achieve the same effect as the above solution, and will not be elaborated here.

[0051] like Figure 7 In one embodiment of this utility model, the specific structure of the limiting groove 610 is designed. In this design, the limiting groove 610 is polygonal in shape, such as a hexagon or pentagon. The limiting body 620 is also a polygonal shape that matches the limiting groove 610. When the limiting body 620 is inserted into the limiting groove 610, the polygonal shape prevents the limiting body 620 from rotating within the limiting groove 610, thereby restricting the rotation of the electrical component 10 relative to the sliding part 220 and further improving the stability of the electrical component 10 installed on the sliding part 220. Furthermore, in... Figure 6 and Figure 7 In another embodiment of this utility model, at least two limiting grooves 610 are provided, and each limiting groove 610 is inserted into a limiting body 620. In this solution, five limiting grooves 610 can be provided, one of which is located at the center of the top of the sliding part 220, and the other four limiting grooves 610 can be arranged at intervals around the central limiting groove 610. This arrangement is equivalent to increasing the number of connection points between the electrical component 10 and the sliding part 220, further ensuring the reliability of the connection. In addition, the size of the central limiting groove 610 can be larger than the size of the other four limiting grooves 610, which can increase the contact area between the electrical component 10 and the sliding part 220, and also help improve the stability of the electrical component 10.

[0052] like Figure 4In one embodiment of the present invention, the electrical box further includes a locking rod 710 and a latch 720. The locking rod 710 is rotatably disposed on one of the sliding part 220 and the electrical component 10, and the latch 720 is disposed on the other of the sliding part 220 and the electrical component 10. The locking rod 710 and the latch 720 engage or disengage to fix or release the electrical component 10. The locking rod 710 has a rod-shaped structure. One end of the locking rod 710 is hinged to the side wall of the electrical component 10 and can swing towards the sliding part 220 below. A latch 720 that cooperates with the locking rod 710 is provided on the side wall of the sliding part 220. The latch 720 can be a ball lock or other structural form. When the electrical component 10 is placed on the sliding part 220, the locking rod 710 can swing towards the latch 720, and the locking rod 710 and the latch 720 can be locked together. At this time, the electrical component 10 and the sliding part 220 are connected as one unit, and the electrical component 10 can be fixed. When it is necessary to disassemble the electrical component 10, the locking rod 710 can be swung in the opposite direction, so that the locking rod 710 is disengaged from the latch 720, thereby unlocking the electrical component 10. This design ensures the reliability of the installation of the electrical component 10 and facilitates the disassembly and assembly of the electrical component 10.

[0053] like Figure 2 In one embodiment of this utility model, the electrical box further includes a heat dissipation component 800, which is disposed in the box body 100. The heat dissipation component 800 is used to drive airflow into and out of the accommodating cavity 110 to dissipate heat from the electrical component 10. The heat dissipation component 800 can be a cooling fan or the like. By delivering airflow into the box body 100 through the heat dissipation component 800 and then exiting the box body 100, the external airflow can be exchanged with the electrical component 10 for heat, thereby improving the heat dissipation efficiency of the electrical component 10 and improving the reliability of the operation of the electrical component 10.

[0054] like Figure 2This utility model provides an embodiment of a heat dissipation component 800. In this solution, the housing 100 is provided with an air inlet 120 and an air outlet 130. The heat dissipation component 800 includes: an airflow generating device 810, which is provided at the air inlet 120 to deliver airflow into the accommodating cavity 110; and a louver 820, which is movably provided at the air outlet 130 to adjust the opening of the air outlet 130. The air inlet 120 can be located on the top of the housing 100. The airflow generating component can be a fan. When the airflow generating component is working, it draws in external air through the air inlet 120. A filter can be installed at the air inlet 120 to ensure the cleanliness of the drawn-in air. In addition, the air outlet 130 can be located on at least one side wall of the housing 100. The drawn-in air can first come into contact with the electrical components 10 and then be discharged from the air outlet 130 to achieve heat dissipation. A louver 820 is also provided at the air outlet 130. The louver 820 can be rotatably installed at the air outlet 130 and can also be driven to rotate by a motor or the like. By rotating the louver 820, the opening of the air outlet 130 can be adjusted, thereby achieving airflow regulation to meet the needs of different airflow sizes.

[0055] like Figure 1 In one embodiment of this utility model, the electrical box further includes telescopic feet 900. The telescopic feet 900 are disposed on the box body 100 and supported on the ground. The telescopic feet 900 are used to adjust the height of the box body 100. The telescopic feet 900 can adopt conventional anchor bolts or similar structural forms. The telescopic feet 900 can be located on the side of the box body 100 facing the ground, and multiple feet can be spaced at intervals around the center of the box body 100. The telescopic feet 900 can be adjusted according to the flatness of the ground to ensure the electrical box is placed stably, improving the adaptability of the equipment. Figure 2 In another embodiment of this utility model, the electrical box further includes a door 1000, which is rotatably connected to the box 100 to open or close the opening. The door 1000 can be rotatably connected to the periphery of the opening of the box 100 via a hinge. A latch 720 can be provided on the door 1000 to lock or unlock the box 100 to open or close the opening. In addition, a transparent observation window can be provided on the door 1000 to facilitate personnel to observe the operating status of the electrical components 10 inside the box 100.

[0056] This utility model also proposes an electrical device, which includes an electrical box for housing electrical components 10. The specific structure of the electrical box is as described in the above embodiments. Since this electrical device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0057] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model.
