Technical Field
[0001] This invention relates to the field of charging pile technology, and in particular to a charging pile that is easy to maintain. Background Technology
[0002] Charging piles are energy-charging devices that provide charging services for electric vehicles. They can charge various models of electric vehicles according to different voltage levels, and are mainly divided into floor-mounted charging piles and wall-mounted charging piles. Wall-mounted charging piles are widely used due to their small footprint. Currently, most existing wall-mounted charging piles use traditional bolts to fix the outer shell, and the internal electrical components are generally also fixed. When repairing the charging pile, the entire pile needs to be disassembled, which cannot be done quickly and causes inconvenience in maintenance.
[0003] How to design a charging station that is easy to maintain is the technical problem that this patent needs to solve. Summary of the Invention
[0004] In order to overcome the shortcomings of existing technologies that cannot achieve quick disassembly and assembly, resulting in inconvenience in maintenance, the technical problem of the present invention is to provide a charging pile that is easy to maintain.
[0005] A maintenance-friendly charging pile includes a charging pile housing and a charging pile cover. The charging pile cover is rotatably connected to the front of the charging pile housing. The charging pile housing also includes a torsion spring, a first telescopic rod, an extension mechanism, and a flattening mechanism. A torsion spring connects the charging pile cover and the charging pile housing. The first telescopic rod is connected to the lower part of the charging pile housing, and a telescopic spring is connected inside the first telescopic rod. A locking slot is opened at the lower part of the charging pile cover, and the front part of the first telescopic rod is locked in the locking slot of the charging pile cover. The charging pile housing has an extension mechanism inside for the PCB board to extend out of the charging pile housing for easy inspection. The lower part of the charging pile housing has a flattening mechanism inside for the PCB board to be placed horizontally for easy maintenance.
[0006] Furthermore, the extension mechanism includes an electric push rod, a magnet, and an iron plate. An electric push rod is installed on the inner rear wall of the charging pile housing. Magnets are connected to the piston rods of the electric push rods. Iron plates are magnetically attracted between the magnets. The electric push rod drives the iron plates forward through the magnets. The iron plates drive the PCB board forward to extend out of the charging pile housing.
[0007] Furthermore, the leveling mechanism includes a multi-stage telescopic rod, a fixing ring, and a second telescopic rod. The multi-stage telescopic rod is connected to the lower side of the rear wall inside the charging pile housing. The front end of each multi-stage telescopic rod is connected to a fixing ring. The lower part of the iron plate is rotatably connected to the fixing ring. The second telescopic rod is connected to the bottom inside the charging pile housing. The second telescopic rod has a telescopic spring connected inside. The upper end of the second telescopic rod rests against the bottom of the iron plate. Pulling the iron plate forward separates it from the magnet. Then, rotating the iron plate backward places it on the second telescopic rod, and the PCB board is placed horizontally.
[0008] Furthermore, it also includes a protection mechanism for power outage protection during maintenance. The protection mechanism includes a positioning plate, a power connector, a power connector assembly, and a lead wheel. The power connector assembly is installed on the top inside the charging pile housing. The positioning plate is connected to the power connector assembly. The power connector is installed on the PCB board. The upper end of the power connector assembly passes through the positioning plate and plugs into the power connector assembly. The lead wheel is rotatably connected to the lower part of the positioning plate. The power connector assembly passes around the lead wheel.
[0009] Furthermore, it also includes a maintenance mechanism for locking the iron plate. The maintenance mechanism includes a third telescopic rod, a bidirectional telescopic rod, a locking block, and a locking pin. The bottom of the charging pile housing is connected to the third telescopic rod, the lower part of the third telescopic rod is locked with a locking pin, the upper end of the third telescopic rod is connected to the bidirectional telescopic rod, and both the left and right ends of the bidirectional telescopic rod are connected with locking blocks.
[0010] Furthermore, the card block is U-shaped.
[0011] Furthermore, it also includes a quick-release mechanism for quickly assembling and disassembling the wall-mounted charging pile. The quick-release mechanism includes an external plug, a protective cover, a fixing block, and an installation slide rail. A fixing block is connected to the rear side of the charging pile housing, and an installation slide rail is slidably connected to each fixing block. An external plug is plugged into the power connection group, and a protective cover is connected to the external plug. The power supply line is passed through the protective cover and connected to the external plug.
[0012] Furthermore, it also includes a placement mechanism for convenient maintenance. The placement mechanism includes a backrest, a foot support, a stop block, an elastic rope, and a placement plate. The placement plate is rotatably connected to the lower right side of the charging pile shell. The backrest is rotatably connected to the placement plate. The foot support is rotatably connected to the backrest. The stop block is connected to the placement plate and is located behind the backrest. The elastic rope is connected to the rear of the placement plate.
[0013] The advantages are as follows: The electric push rod moves the iron plate forward via a magnet, which in turn moves the PCB board forward to extend it out of the charging pile housing, facilitating inspection of the PCB board by maintenance personnel. Pulling the iron plate forward separates it from the magnet, and then rotating it backward places it on the second telescopic rod, horizontally positioning the PCB board for easy maintenance. When the PCB board extends forward out of the charging pile housing, it pulls the power connector, causing it to detach from the power connector assembly for forced power-off protection, preventing safety accidents. By securing the locking block to the iron plate, from... The iron plate is positioned to prevent rotation and maintain its position during maintenance. The mounting rails are installed on the wall, and the charging pile casing is secured to the rails with fixing blocks, allowing for quick installation and removal of the wall-mounted charging pile. When removing the charging pile from the wall, the external plug can be unplugged to disconnect the power supply cable, eliminating the need for technicians to disconnect the wires. When using a multimeter for inspection, technicians can rest the multimeter against the backplate and use the multimeter probes to check the PCB board, eliminating the need for technicians to hold the multimeter while performing the inspection.

Detailed Implementation
[0026] The technical solution of the present invention will be further described below with reference to the accompanying drawings.
[0027] Example 1
[0028] A charging station that is easy to maintain, refer to Figures 1-5 The charging pile includes a charging pile housing 1, a charging pile cover plate 2, a torsion spring 3, a first telescopic rod 4, an extension mechanism 5, and a flattening mechanism 6. The charging pile cover plate 2 is rotatably connected to the front of the charging pile housing 1. Two torsion springs 3 are connected between the charging pile cover plate 2 and the charging pile housing 1. The first telescopic rod 4 is installed at the lower part of the charging pile housing 1. The first telescopic rod 4 is internally connected to a telescopic spring. The lower part of the charging pile cover plate 2 has a locking slot. The front part of the first telescopic rod 4 is locked in the locking slot of the charging pile cover plate 2. The charging pile housing 1 has an extension mechanism 5 inside for the PCB board to extend out of the charging pile housing 1 for easy inspection. The lower part of the charging pile housing 1 has a flattening mechanism 6 inside for the PCB board to be placed horizontally for easy maintenance.
[0029] Reference Figures 3-4 The extension mechanism 5 includes an electric push rod 51, a magnet 52 and an iron plate 53. Four electric push rods 51 are installed on the inner rear wall of the charging pile housing 1. Magnets 52 are connected to the piston rods of the four electric push rods 51. An iron plate 53 is magnetically attracted between the four magnets 52. The iron plate 53 is used to install the PCB board.
[0030] Reference Figure 5 The leveling mechanism 6 includes a multi-stage telescopic rod 61, a fixing ring 62, and a second telescopic rod 63. Two multi-stage telescopic rods 61 are installed on the lower side of the inner rear wall of the charging pile housing 1. The front end of each multi-stage telescopic rod 61 is welded with a fixing ring 62. The lower part of the iron plate 53 is rotatably connected to the fixing ring 62. Two second telescopic rods 63 are installed at the bottom inside the charging pile housing 1. The second telescopic rod 63 is internally connected to a telescopic spring, and the upper end of the second telescopic rod 63 abuts against the bottom of the iron plate 53.
[0031] The PCB board is mounted on the iron plate 53. Initially, the torsion spring 3 deforms, and the telescopic spring inside the second telescopic rod 63 is stretched. When repairing the PCB board, the first telescopic rod 4 is manually pressed, and the telescopic spring inside the first telescopic rod 4 is compressed, causing the front part of the first telescopic rod 4 to disengage from the locking jaw of the charging pile cover 2. The first telescopic rod 4 is released, and it resets under the action of the telescopic spring. Simultaneously, under the action of the torsion spring 3, it drives the charging pile cover 2 to rotate upward and open. Then, the electric push rod 51 is activated, controlling the piston rod of the electric push rod 51 to drive the iron plate 53 forward through the magnet 52. The iron plate 53 drives the fixing ring 62 and the PCB board forward, so that the PCB board extends out of the charging pile housing 1, making it convenient for the repairman to inspect the PCB board. Then, the electric push rod 51 is closed. When the iron plate 53 moves forward, the iron plate 53 separates from the second telescopic rod 63. The second telescopic rod 63 resets under the action of the telescopic spring. Then, the repairman manually pulls the iron plate 53 forward to separate it from the magnet 52. The iron plate 53 drives the PCB board and the fixing ring 62 to rotate upward and open. 2. Move forward, the multi-stage telescopic rod 61 extends, then manually rotate the iron plate 53 backward. The iron plate 53 drives the PCB board to rotate backward and place it on the second telescopic rod 63, facilitating the repairman's repair of the PCB board. After the repair is completed, manually rotate the iron plate 53 forward to reset it, then manually push the iron plate 53 backward to attract it to the magnet 52. Subsequently, activate the electric push rod 51, controlling the piston rod of the electric push rod 51 to drive the iron plate 53 backward to reset via the magnet 52. When the iron plate 53 moves backward and contacts the upper end of the second telescopic rod 63... When the iron plate 53 pushes the second telescopic rod 63 to retract, the telescopic spring inside the second telescopic rod 63 is stretched. Then the charging pile cover 2 is closed, the torsion spring 3 deforms. When the charging pile cover 2 contacts the front end of the first telescopic rod 4, the charging pile cover 2 pushes the first telescopic rod 4 to retract, the telescopic spring inside the first telescopic rod 4 is compressed. When the front part of the first telescopic rod 4 corresponds to the locking hole of the charging pile cover 2, the first telescopic rod 4 is reset under the action of the telescopic spring, so that the front part of the first telescopic rod 4 is stuck in the locking hole of the charging pile cover 2.
[0032] Example 2
[0033] Based on Example 1, referring to Figure 1 , Figure 2 , Figure 6 and Figure 7 It also includes a protection mechanism 7, which includes a positioning plate 71, a power connector 73, a power connector group 74, and a lead wheel 75. The power connector group 74 is installed on the top inside the charging pile housing 1, and the positioning plate 71 is installed on the power connector group 74. The power connector 73 is installed on the PCB board, and the upper end of the power connector 73 passes through the positioning plate 71 and is inserted into the power connector group 74. The lead wheel 75 is rotatably connected to the lower part of the positioning plate 71, and the power connector 73 passes around the lead wheel 75.
[0034] When the PCB moves forward and extends out of the charging pile housing 1, the PCB pulls the power connector 73, causing the power connector 73 to disengage from the power connector group 74 for forced power-off protection to prevent safety accidents. After the maintenance is completed, the PCB moves backward to reset and then the power connector 73 is plugged into the power connector group 74.
[0035] Reference Figure 1 , Figure 2 and Figure 8 It also includes a maintenance mechanism 8, which includes a third telescopic rod 81, a bidirectional telescopic rod 82, a locking block 83, and a locking pin 84. The third telescopic rod 81 is installed at the bottom inside the charging pile housing 1. The lower part of the third telescopic rod 81 is locked with a locking pin 84. The upper end of the third telescopic rod 81 is welded with a bidirectional telescopic rod 82. Both the left and right ends of the bidirectional telescopic rod 82 are welded with locking blocks 83, which are U-shaped.
[0036] After the iron plate 53 drives the PCB board to rotate backward and place it on the second telescopic rod 63, remove the locking pin 84, manually stretch the third telescopic rod 81 so that the locking block 83 and the iron plate 53 are on the same horizontal plane, then reset the locking pin 84 to lock the third telescopic rod 81. Then manually move the locking block 83 outward, and the bidirectional telescopic rod 82 extends. Since the locking block 83 is U-shaped, it locks the iron plate 53, thereby locking the iron plate 53 and preventing the iron plate 53 from rotating and affecting the maintenance. After the maintenance is completed, manually move the locking block 83 inward to reset it, then remove the locking pin 84, manually retract and reset the third telescopic rod 81, and then reset the locking pin 84.
[0037] Reference Figure 1 , Figure 2 and Figure 9 It also includes a quick-release mechanism 9, which includes an external plug 91, a protective cover 92, a fixing block 93, and a mounting rail 94. Two fixing blocks 93 are installed on the rear side of the charging pile housing 1. The mounting rail 94 is slidably connected to each fixing block 93. An external plug 91 is plugged into the power connection group 74. The external plug 91 is connected to the protective cover 92. The power supply line is passed through the protective cover 92 and connected to the external plug 91.
[0038] The mounting rail 94 is installed on the wall, and the charging pile housing 1 is secured to the mounting rail 94 by the fixing block 93, enabling quick installation and removal of the wall-mounted charging pile. By passing the power supply line through the protective cover 92 and connecting it to the external plug 91, the external plug 91 can be unplugged when the charging pile is removed from the wall, thus separating the power supply line from the charging pile without the need for a maintenance worker to disassemble the wires.
[0039] Reference Figure 1 , Figure 2 , Figure 10 and Figure 11It also includes a placement mechanism 10, which includes a backing plate 101, a foot support 102, a stop block 103, an elastic rope 104, and a placement plate 105. The placement plate 105 is rotatably connected to the lower right side of the charging pile housing 1. The backing plate 101 is rotatably connected to the placement plate 105. The foot support 102 is rotatably connected to the rear side of the backing plate 101. The stop block 103 is welded to the placement plate 105 and is located behind the backing plate 101. The elastic rope 104 is connected to the rear of the placement plate 105.
[0040] During maintenance, manually open the placement plate 105 to the right, then stand the back plate 101 upright. The back plate 101 is supported by the foot support 102, which abuts against the stop block 103. When the maintenance personnel are inspecting with a multimeter, they can place the multimeter against the back plate 101 and use the multimeter probes to check the PCB board. This eliminates the need for the maintenance personnel to hold the multimeter, allowing for better inspection. After maintenance, remove the multimeter, retract the foot support 102, and reset the back plate 101. Press the back plate 101 down with the elastic rope 104 to limit its movement.
