Description

Technical Field

[0001] This application relates to the field of power distribution technology, and more particularly to a power distribution cabinet. Background Technology

[0002] A distribution cabinet is an important piece of equipment used for power distribution and management, widely used in industrial, commercial, and residential sectors. Its main function is to rationally distribute electrical energy within a power system and provide protection and control for electrical equipment. Distribution cabinets typically include controllers and cooling systems to ensure the safety and stability of the power supply. In modern electrical systems, the design of distribution cabinets is increasingly moving towards modularity and intelligence to improve the convenience of installation and maintenance, as well as the reliability of system operation.

[0003] The existing power distribution cabinet structure has certain defects. The controller and heat dissipation device in the power distribution cabinet usually need to be fixed inside the cabinet with screws. This method is not only cumbersome to install, but also requires operators to tighten or loosen the screws in a small space, which is quite difficult to operate.

[0004] To address the aforementioned issues, there is an urgent need for a new type of power distribution cabinet structure to optimize the installation and disassembly of controllers and heat dissipation devices, simplify operating procedures, and improve maintenance convenience. Utility Model Content

[0005] The purpose of this application is to overcome the shortcomings of the prior art and propose a power distribution cabinet that solves the problem of cumbersome installation or disassembly of controllers and heat dissipation devices.

[0006] This application is achieved through the following technical solution:

[0007] This application proposes a power distribution cabinet, including a cabinet body and a controller and a heat dissipation device disposed in the cabinet body. The controller is detachably disposed on the heat dissipation device. The inner wall of the cabinet body is provided with a snap-fit ​​structure. The heat dissipation device includes a heat dissipation frame and a snap-fit ​​plate fixedly connected to the heat dissipation frame. The snap-fit ​​plate can be snapped onto the snap-fit ​​structure.

[0008] The distribution cabinet also includes a locking mechanism, which includes a sliding locking member and a rotating locking member. The sliding locking member is slidably connected to the inner wall of the cabinet, and the rotating locking member is rotatably connected to the inner wall of the cabinet. The sliding locking member is located above the rotating locking member.

[0009] A snap-fit ​​groove is formed between the top of the heat sink and the snap-fit ​​plate. When the snap-fit ​​plate is snapped onto the snap-fit ​​structure, the rotating locking member extends rotatably into the snap-fit ​​groove, and the locking mechanism slides downward and abuts against the rotating locking member to fix the rotating locking member.

[0010] In one embodiment of this application, the rotating locking member includes a first rotating part, a second rotating part, and a first hand-held part. The first rotating part and the second rotating part are perpendicular to each other and fixedly connected. The first hand-held part is disposed at the connection between the first rotating part and the second rotating part. The first rotating part is rotatably connected to the cabinet.

[0011] The first hand-held part can drive the first rotating part to rotate, so as to drive the second rotating part to extend into the snap-fit ​​groove or disengage from the snap-fit ​​groove.

[0012] In one embodiment of this application, the sliding lock member includes a sliding part and a second hand-held part. The sliding part is slidably connected to the inner wall of the cabinet, and the second hand-held part is fixedly connected to the side of the sliding part opposite to the inner wall of the cabinet.

[0013] The second hand-held part can drive the sliding part to slide downward so that the sliding part abuts against the first rotating part;

[0014] The second hand-held part can drive the sliding part to slide upward so that the sliding part is separated from the first rotating part.

[0015] In one embodiment of this application, the first rotating part is provided with a rotating shaft at both ends, and two connecting parts are provided on the inner wall of the cabinet. Each of the two connecting parts is provided with a positioning hole. The two positioning holes are on the same central axis, and the two rotating shafts extend into one of the positioning holes respectively. The first rotating part can rotate around the circumference of the positioning hole.

[0016] In one embodiment of this application, the rotating shaft is provided with a damping layer, so that the rotating locking member has resistance during rotation.

[0017] In one embodiment of this application, two guide rails are provided on the inner wall of the cabinet, and the sliding locking member is disposed between the two guide rails and slidably connected to the two guide rails.

[0018] In one embodiment of this application, the snap-fit ​​structure includes a first snap-fit ​​strip, a second snap-fit ​​strip, and a third snap-fit ​​strip. The first snap-fit ​​strip and the second snap-fit ​​strip are parallel to each other and perpendicular to each other. The third snap-fit ​​strip is located below the first snap-fit ​​strip and the second snap-fit ​​strip.

[0019] The spacing between the first and second snap-fit ​​strips is equal to the length of the snap-fit ​​plate. When the snap-fit ​​plate is snapped onto the snap-fit ​​structure, the third snap-fit ​​strip abuts against the bottom of the snap-fit ​​plate, the first snap-fit ​​strip abuts against the side of the snap-fit ​​plate, and the second snap-fit ​​strip abuts against the other side of the snap-fit ​​plate.

[0020] In one embodiment of this application, the heat dissipation device further includes a mounting plate, which is fixedly connected to the heat dissipation frame, and bolts can pass through the controller and be threadedly connected to the mounting plate.

[0021] Compared with the prior art, the beneficial effects of this application are:

[0022] The distribution cabinet includes a cabinet body and a controller and a heat dissipation device housed within the cabinet. The controller is detachably mounted on the heat dissipation device. The inner wall of the cabinet body has a snap-fit ​​structure. The heat dissipation device includes a heat dissipation frame and a snap-fit ​​plate fixedly connected to the heat dissipation frame. The snap-fit ​​plate can be snapped onto the snap-fit ​​structure. The locking mechanism includes a sliding locking member and a rotating locking member. The sliding locking member is slidably connected to the inner wall of the cabinet body, and the rotating locking member is rotatably connected to the inner wall of the cabinet body. The sliding locking member is located above the rotating locking member. A snap-fit ​​groove is formed between the top of the heat dissipation frame and the snap-fit ​​plate. During installation, the controller is mounted on the heat dissipation device. The snap-fit ​​plate of the heat dissipation frame first snaps onto the snap-fit ​​structure of the cabinet body to form a snap-fit ​​fixation. Subsequently, the rotating locking member rotates and extends into the snap-fit ​​groove formed between the top of the heat dissipation frame and the snap-fit ​​plate, achieving the first step of locking. Finally, the sliding locking member slides downward and abuts against the rotating locking member, thereby fixing the rotating locking member and completing the stable installation of the heat dissipation device. During disassembly, simply slide the sliding locking member upwards, then rotate the rotating locking member to disengage it from the locking slot, allowing the controller and heat sink to be removed together. This design eliminates the need for screws, freeing operators from complex screw tightening or disassembly in confined spaces, significantly improving installation and disassembly efficiency and simplifying maintenance.

[0038] Please refer to Figures 1 to 5 This application proposes a power distribution cabinet 10, including a cabinet 100 and a controller 200 and a heat dissipation device 300 disposed in the cabinet 100. The controller 200 is detachably disposed on the heat dissipation device 300. The inner wall of the cabinet 100 is provided with a snap-fit ​​structure (not shown in the figure). The heat dissipation device 300 includes a heat dissipation frame 310 and a snap-fit ​​plate 320 fixedly connected to the heat dissipation frame 310. The snap-fit ​​plate 320 can be snapped onto the snap-fit ​​structure.

[0039] The distribution cabinet 10 also includes a locking mechanism 120, which includes a sliding locking member 121 and a rotating locking member 122. The sliding locking member 121 is slidably connected to the inner wall of the cabinet 100, and the rotating locking member 122 is rotatably connected to the inner wall of the cabinet 100. The sliding locking member 121 is located above the rotating locking member 122.

[0040] A snap-fit ​​groove 330 is formed between the top of the heat sink 310 and the snap-fit ​​plate 320. When the snap-fit ​​plate 320 is snapped onto the snap-fit ​​structure, the rotating locking member 122 rotates into the snap-fit ​​groove 330, and the locking mechanism 120 slides downward and abuts against the rotating locking member 122 to fix the rotating locking member 122.

[0041] Specifically, the controller 200 is detachably mounted on the heat dissipation device 300, which includes a heat dissipation frame 310 and a fixedly connected snap-fit ​​plate 320. The snap-fit ​​plate 320 can cooperate with the snap-fit ​​structure of the inner wall of the cabinet 100. The locking mechanism 120 includes a sliding locking member 121 and a rotating locking member 122, wherein the sliding locking member 121 is slidably connected to the inner wall of the cabinet 100, and the rotating locking member 122 is rotatably connected to the inner wall of the cabinet 100, and the sliding locking member 121 is located above the rotating locking member 122. During installation, the controller 200 is mounted on the heat dissipation device 300. The snap-fit ​​plate 320 of the heat dissipation bracket 310 is first snapped onto the snap-fit ​​structure of the cabinet 100 to form a snap-fit ​​fixation. Then, the rotating locking member 122 rotates and extends into the snap-fit ​​groove 330 formed between the top of the heat dissipation bracket 310 and the snap-fit ​​plate 320 to achieve the first step of locking. Finally, the sliding locking member 121 slides down and abuts against the rotating locking member 122, thereby fixing the rotating locking member 122 and completing the stable installation of the heat dissipation device 300.

[0042] Disassembly is also simple: first slide the sliding locking member 121 upwards, then rotate the rotating locking member 122 to disengage it from the locking slot 330, and the controller 200 and the heat dissipation device 300 can be removed together.

[0043] This design eliminates the need for screws, freeing operators from complex screw tightening or disassembly in confined spaces. This significantly improves installation and disassembly efficiency, simplifies maintenance, and gives the distribution cabinet 10 remarkable advantages such as quick installation or disassembly and easy operation.

[0044] Please refer to Figures 2 to 4 In one embodiment, the rotating locking member 122 includes a first rotating part 1221, a second rotating part 1222, and a first hand-held part 1223. The first rotating part 1221 and the second rotating part 1222 are perpendicular to each other and fixedly connected. The first hand-held part 1223 is disposed at the connection between the first rotating part 1221 and the second rotating part 1222. The first rotating part 1221 is rotatably connected to the cabinet 100. The first hand-held part 1223 can drive the first rotating part 1221 to rotate, so as to drive the second rotating part 1222 to extend into the locking groove 330 or disengage from the locking groove 330.

[0045] Specifically, the rotating locking member 122 is used to fix the heat dissipation device 300. The rotating locking member 122 includes a first rotating part 1221, a second rotating part 1222, and a first handheld part 1223. The first rotating part 1221 is rotatably connected to the cabinet 100, and the second rotating part 1222 is perpendicular to and fixedly connected to the first rotating part 1221, forming an L-shaped structure to achieve the locking function. The first handheld part 1223 is located at the connection between the first rotating part 1221 and the second rotating part 1222. The operator can drive the first rotating part 1221 to rotate through the first handheld part 1223, thereby driving the second rotating part 1222 to extend downward into the locking groove 330 of the heat dissipation frame 310 to complete the fixation of the heat dissipation frame 310. Conversely, when it is necessary to disassemble the heat dissipation device 300, the operator can hold the first handheld part 1223 to make the first rotating part 1221 rotate in the opposite direction, thereby driving the second rotating part 1222 to disengage from the locking groove 330, thereby realizing the unlocking operation. This design allows the heat dissipation device 300 to be locked or unlocked with a simple rotation, avoiding the complicated operation of using screws in the traditional method, making the installation and disassembly process more convenient, while ensuring the stability of the fixed structure.

[0046] Please refer to Figures 2 to 4 In one embodiment, the sliding lock connector 121 includes a sliding part 1211 and a second hand-held part 1212. The sliding part 1211 is slidably connected to the inner wall of the cabinet 100, and the second hand-held part 1212 is fixedly connected to the side of the sliding part 1211 that is away from the inner wall of the cabinet 100.

[0047] The second hand-held part 1212 can drive the sliding part 1211 to slide downward so that the sliding part 1211 abuts against the first rotating part 1221; the second hand-held part 1212 can drive the sliding part 1211 to slide upward so that the sliding part 1211 separates from the first rotating part 1221.

[0048] Specifically, the sliding lock connector 121 includes a sliding part 1211 and a second hand-held part 1212. The sliding part 1211 is slidably connected to the inner wall of the cabinet 100 and can move up and down. The second hand-held part 1212 is fixedly connected to the outside of the sliding part 1211 for easy manual control by the operator. After the heat dissipation device 300 is installed in place, the operator drives the first rotating part 1221 to rotate through the first hand-held part 1223, thereby causing the second rotating part 1222 to extend downward into the locking groove 330 of the heat dissipation frame 310, thus fixing the heat dissipation frame 310. Then, the operator pushes the second hand-held part 1212 to slide the sliding part 1211 downward, so that the sliding part 1211 abuts against the top of the first rotating part 1221, thereby locking the rotating lock connector 122 a second time to prevent it from loosening or accidentally opening due to external force or vibration. When the heat dissipation device 300 needs to be disassembled, the operator can push the second hand-held part 1212 upwards, causing the sliding part 1211 to move upwards and disengage from the first rotating part 1221, thereby releasing the rotating locking member 122 and allowing the rotating locking member 122 to be rotated and unlocked. This design improves the stability of the heat dissipation device 300 by limiting and locking the rotating locking member 122 with the sliding locking member 121, and provides a smooth and convenient operation during installation and disassembly, avoiding the cumbersome operation of traditional screw fixing methods.

[0049] Please refer to Figure 2 In one embodiment, the first rotating part 1221 has a rotating shaft (not marked in the figure) at both ends. The inner wall of the cabinet 100 has two connecting parts 130. Each of the two connecting parts 130 has a positioning hole (not marked in the figure). The two positioning holes are on the same central axis. The two rotating shafts extend into one positioning hole respectively. The first rotating part 1221 can rotate around the circumference of the positioning hole.

[0050] Specifically, the first rotating part 1221 has a rotating shaft at both ends, and the inner wall of the cabinet 100 has two connecting parts 130 accordingly. Each connecting part 130 has a positioning hole, and the two positioning holes are located on the same central axis, thereby ensuring that after the rotating shaft is inserted into the positioning hole, the first rotating part 1221 can rotate freely around the circumference of the positioning hole. During installation, after the rotating shaft is inserted into the positioning hole, the first rotating part 1221 rotates around the axis of the positioning hole, driving the second rotating part 1222 to lock or unlock the heat dissipation device 300.

[0051] Please refer to Figure 2 and Figure 3 In one embodiment, the rotating locking member 122 is made to have resistance during rotation.

[0052] Specifically, a damping layer is provided on the outer surface of the rotating shaft to provide appropriate rotational resistance during locking or unlocking, forming frictional damping between the rotating shaft and the inner wall of the positioning hole to improve operational stability and safety. The damping layer is made of a high-friction elastic material or a damping coating, covering the outside of the rotating shaft and contacting the inner wall of the positioning hole in the inner wall of the cabinet 100, thereby generating appropriate damping force when the first rotating part 1221 rotates around the rotating shaft, improving the stability of the rotating locking member 122.

[0053] Please refer to Figure 2 and Figure 3 In one embodiment, two guide rails 140 are provided on the inner wall of the cabinet 100, and a sliding locking member 121 is disposed between the two guide rails 140 and slidably connected to the two guide rails 140.

[0054] Specifically, the sliding part 1211 of the sliding lock connector 121 is fitted with the two guide rails 140, and the guide rails 140 allow it to slide vertically along the inner wall of the cabinet 100, thus making the operation of the sliding lock connector 121 smoother and more precise. During the locking process, the sliding lock connector 121 moves down along the guide rail 140 and abuts against the first rotating part 1221, thereby completing the secondary locking; during unlocking, the sliding lock connector 121 moves up along the guide rail 140, separating it from the first rotating part 1221 and releasing the fixed state.

[0055] Please refer to Figure 4 and Figure 5 In one embodiment, the snap-fit ​​structure includes a first snap-fit ​​strip 111, a second snap-fit ​​strip 112, and a third snap-fit ​​strip 113. The first snap-fit ​​strip 111 and the second snap-fit ​​strip 112 are parallel to each other and perpendicular to each other with the third snap-fit ​​strip 113. The third snap-fit ​​strip 113 is located below the first snap-fit ​​strip 111 and the second snap-fit ​​strip 112.

[0056] The distance between the first snap-fit ​​strip 111 and the second snap-fit ​​strip 112 is equal to the length of the snap-fit ​​plate 320. When the snap-fit ​​plate 320 is snapped onto the snap-fit ​​structure, the third snap-fit ​​strip 113 abuts against the bottom of the snap-fit ​​plate 320, the first snap-fit ​​strip 111 abuts against the side of the snap-fit ​​plate 320, and the second snap-fit ​​strip 112 abuts against the other side of the snap-fit ​​plate 320.

[0057] Specifically, the spacing between the first snap-fit ​​strip 111 and the second snap-fit ​​strip 112 matches the length of the snap-fit ​​plate 320, ensuring that the snap-fit ​​plate 320 can be accurately inserted and avoiding loosening or over-tightening during installation. Simultaneously, the third snap-fit ​​strip 113 is located below the first and second snap-fit ​​strips 111 and abuts against the bottom of the snap-fit ​​plate 320, providing additional vertical support and further enhancing the stability of the snap-fit. When the snap-fit ​​plate 320 is installed in place, the third snap-fit ​​strip 113 abuts against the bottom of the snap-fit ​​plate 320, the first snap-fit ​​strip 111 abuts against the side of the snap-fit ​​plate 320, and the second snap-fit ​​strip 112 abuts against the other side of the snap-fit ​​plate 320, forming a three-way limiting fixation, ensuring that the heat dissipation device 300 can be firmly installed inside the cabinet 100 and preventing loosening or displacement due to external forces or vibrations.

[0058] Please refer to Figure 4 In one embodiment, the heat dissipation device 300 further includes a mounting plate 340, which is fixedly connected to the heat dissipation bracket 310, and bolts can pass through the controller 200 and be threadedly connected to the mounting plate 340.

[0059] Specifically, bolts can pass through the controller 200 and be threaded onto the mounting plate 340, so that the controller 200 can be detachably mounted on the heat dissipation device 300.

[0060] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
