Under the same power, the size of charging piles is required to be smaller and smaller. As the main component of the charging pile, the size of the cold source is also required to be smaller and smaller. The charging market is becoming more and more complete, and the guarantee for maintenance is getting higher and higher. The convenience of maintenance is indispensable.

[0003] Traditional electric control boxes are usually fixed inside or on the top of the cold source box. When fixed inside the cold source, it is necessary to open the box cover for maintenance, and even more so, it is necessary to remove the refrigerant for maintenance. The cold source is often installed on the top of the charging equipment, which requires high-altitude work to complete. Due to environmental influences and conditions, it is quite difficult to open the box cover at a high altitude, and there is no space to place the cover; if the electric control box is placed on the top of the cold source, it is more convenient to open, but the waterproof performance is poor, and the sealing strip is prone to aging and failure due to long-term exposure to the outdoor environment. Moreover, the electric control box is usually fixed with dustproof parts, usually dustproof plates, at the heat dissipation holes by bolts. When the dustproof plates need to be maintained after long-term use, the removal and installation process of the dustproof plates is relatively complicated, time-consuming and labor-intensive.

[0004] Therefore, there is a need for an electric control box with a drawer-type structure to solve the problems in the prior art that the maintenance process of the traditional electric control box is relatively cumbersome and the installation and removal of the dustproof parts on the electric control box are relatively complicated.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] See also Figure 1-Figure 5The utility model provides an electric control box with a drawer-type structure, comprising a cold source box 1, an electric control box body 2 being slidably arranged inside the cold source box 1, a cover plate 3 being fixedly connected to the outer wall of one end of the electric control box body 2, a handle 4 being fixedly connected to the outer wall of one end of the cover plate 3, a plurality of evenly distributed heat dissipation holes 5 being penetrated through the outer wall of one end of the cover plate 3, and a dustproof mechanism 6 cooperating with the plurality of heat dissipation holes 5 being arranged on the outer wall of one end of the cover plate 3;

[0024] The dustproof mechanism 6 includes an air intake frame 61, which is fixedly connected to the outer wall of one end of the cover plate 3. The inner walls on both sides of the air intake frame 61 are fixedly connected with positioning plates 62, and the same dustproof plate 63 is placed on the two positioning plates 62. The inner walls on both sides of the air intake frame 61 are provided with an accommodating cavity 64, and a plug-in block 65 is slidably connected inside the accommodating cavity 64. The plug-in block 65 is fixedly connected to the center of the outer wall on the side away from the dustproof plate 63, and a reset spring 67 is sleeved on the outer surface of the pull rod 66. The outer walls on both sides of the dustproof plate 63 are provided with slots 68 that are compatible with the plug-in blocks 65. The two plug-in blocks 65 are respectively plugged into the two slots 68 on the side away from the pull rod 66.

[0025] Further as Figure 1 、 Figure 4 and Figure 5 As shown, it is worth mentioning that the dust-proof mechanism 6 also includes two parallel through grooves 69 and two locking grooves 614. The two through grooves 69 are both opened on the outer wall of one end of the air intake frame 61 and are respectively communicated with the two accommodating cavities 64. The two locking grooves 614 are respectively opened on the outer wall of one end of the two plug-in blocks 65. An insertion rod 610 is inserted into the through groove 69. The outer wall of the end of the insertion rod 610 away from the through groove 69 is coaxially fixedly connected with a pull plate 611. A tensioning spring 612 is sleeved on the outer surface of the insertion rod 610, and a pull ring 613 is provided at the center of the outer wall of the end of the pull plate 611 away from the insertion rod 610.

[0026] Further as Figure 2 and Figure 3 As shown, it is worth mentioning that the top surface of the electric control box 2 is fixedly connected with a large sealing strip 7, a large cover plate 8, a small sealing strip 9 and a small cover plate 10 by nuts and screws, the inner walls on both sides of the electric control box 2 are fixedly connected with wire binding vertical rods 11 and wire binding horizontal rods 12, and two sets of grounding studs 13 are provided on the inner wall of the bottom surface of the electric control box 2.

[0027] Further as Figure 2 and Figure 3 As shown, it is worth mentioning that the outer walls on both sides of the electric control box 2 are fixedly connected with guide plates 14 by hexagonal screws, so as to facilitate the sliding of the electric control box 2 inside the cold source box 1, and a drag chain plate 15 is provided on the outer wall of one end of the electric control box 2 away from the cover plate 3, and a drag chain 16 is installed on the bottom surface of the drag chain plate 15.

[0028] Further as Figure 4 and Figure 5 As shown, it is worth mentioning that the two pull rods 66 slide through the outer walls of the air intake frame 61 on the side away from the plug-in block 65, so that the operator can pull the pull rods 66. The two sides of the reset spring 67 are fixedly connected to the inner side wall of the accommodating cavity 64 and the outer wall of the plug-in block 65, respectively. The automatic reset of the plug-in block 65 is achieved by the action of the reset spring 67.

[0029] Further as Figure 4 and Figure 5 As shown, it is worth mentioning that the two ends of the tensioning spring 612 are fixedly connected to the outer wall of one end of the air intake frame 61 and the outer wall of one end of the pull plate 611, respectively. The tensioning spring 612 is used to push the insertion rod 610 into the locking groove 614. The through groove 69 and the locking groove 614 are located on the same axis to ensure the cooperation between the insertion rod 610 and the locking groove 614.

[0030] In summary: when the electric control box needs to be repaired, with the cooperation of the guide plate 14 and the drag chain 16 and the cold source box 1, the operator only needs to pull the handle 4 to move the electric control box 2, and pull the electric control box 2 until the large cover 8 is completely placed outside the cold source box 1 for maintenance. The provided handle 4 can be used to pull the electric control box 2, and can also prevent the aviation socket below from being exposed to rain. At the same time, the wire binding vertical rods 11 and wire binding horizontal rods 12 provided inside the electric control box 2 provide fixed points for the internal lines, and the large sealing strip 7 provided on the bottom of the large cover 8 and the small sealing strip 9 provided on the bottom of the small cover 10 ensure the sealing effect inside the electric control box 2, thereby improving the waterproofness of the electric control box 2. After the maintenance is completed, the electric control box 2 slides to the inside of the cold source box 1 under the action of the drag chain 16, and the electric control box 2 is reset, effectively avoiding the more cumbersome problem of the traditional electric control box maintenance process.

[0031] When the electric control box 2 is working normally, the dustproof plate 63 blocks the dust from the outside to prevent the dust from entering the electric control box 2 through the heat dissipation holes 5. When the dustproof plate 63 needs to be disassembled for maintenance, the operator pulls the two pull rods 66 to both sides at the same time. The two pull rods 66 respectively drive the two plug-in blocks 65 to separate from the two slots 68. At this time, the reset spring 67 is forced to contract. When the plug-in block 65 moves to the locking groove 614 and is coaxial with the through groove 69, the tensioning spring 612 pushes the plug-in rod 610 to insert into the locking groove 614, locking the plug-in block 65 to a limit position, and then the operator The author can pull the dustproof plate 63 outward to separate it from the air intake frame 61 to complete the disassembly of the dustproof plate 63. After the dustproof plate 63 is replaced in the air intake frame 61 after maintenance, the two pull rings 613 are pulled at the same time to drive the two plug rods 610 to move, so that the plug rods 610 and the locking grooves 614 are separated from each other. Under the elastic action of the reset spring 67, the plug-in block 65 is pushed to be reinserted into the slot 68 to fix the dustproof plate 63, thereby completing the installation of the dustproof plate 63. The operation is simple and effectively avoids the problem of complicated installation and disassembly of dustproof parts on the electrical control box.
