An insulation monitoring device for a new energy charging pile

Abstract

This utility model relates to an insulation monitoring device for a new energy charging pile, including a charging pile body, a plug, a housing, a conductive ring, and a metal plate. A plug is provided on one side of the charging pile body via a cable. A metal plate is located inside the housing on the surface of the charging pile body. The conductive ring is installed on the surface of the plug and is located in a groove at the top of the metal plate. A housing for storing the plug is provided on one side of the charging pile body. Because the conductive ring on the plug surface is in contact with the metal plate, and the metal plate is electrically connected to a dual-axis motor via a wire, when the plug leaks current, the dual-axis motor drives the two output rods to rotate, ultimately causing the cams on the output rod surfaces to rotate. The rotation of the cams squeezes the push plate, thereby continuously pushing the push plate to move. When the cam rotates for the first time and pushes the push plate to move, the contact frame does not limit the horizontal bar. Under the action of two springs, the two toothed plates are pushed out, realizing the rotation of the baffle to block the plug inside the housing.

[0002] During the use of new energy vehicle charging stations, leakage often occurs because the charging head is frequently plugged and unplugged. When the charging head leaks electricity, there is no way to alert people around. In the existing technology, when the charging head leaks electricity, it is impossible to store and cover the charging head, and it cannot alert the user. The charging station has a certain degree of danger and lacks a warning function.

[0004] The aforementioned patent has the drawback of not being able to shield the leaking charging head and not being able to alert people around that the charging pile is leaking electricity. Therefore, we need to provide an insulation monitoring device for new energy charging piles. Summary of the Invention

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution: an insulation monitoring device for new energy charging piles, comprising: The charging pile body 1, plug 2, box 3, conductive ring 4 and metal plate 5 are provided. The plug 2 is provided on one side of the charging pile body 1 through a cable. The metal plate 5 is provided inside the box 3 on the surface of the charging pile body 1. The conductive ring 4 is installed on the surface of the plug 2 and is located in the groove at the top of the metal plate 5. The surface of the conductive ring 4 is in contact with the metal plate 5. When the plug 2 leaks current, the current will be transmitted to the metal plate 5 through the conductive ring 4. The top of the metal plate 5 is provided with a groove to facilitate the placement of the conductive ring 4.

[0019] It also includes a sealing mechanism 6, which is used to shield and protect the plug 2. The sealing mechanism 6 includes a baffle 61, a gear 62, a rod 63, a toothed plate 64 and a spring 65. The rod 63 is rotatably mounted on the top of the box 3. The baffle 61 is fixedly mounted on the surface of the rod 63, and two gears 62 are provided on the surface of the rod 63. The gears 62 are located in the grooves inside the baffle 61. The toothed plate 64 is meshed on one side of each of the two gears 62. A spring 65 is provided between the bottom of the toothed plate 64 and the bottom of the inner wall of the box 3. Specifically, a box 3 for storing the plug 2 is provided on one side of the charging pile body 1. Since the conductive ring 4 on the surface of the plug 2 is attached to the metal plate 5, and the metal plate 5 is electrically connected to the dual-axis motor 8 through wires, when the plug 2 leaks current, the dual-axis motor 8 is driven to make the baffle 61 cover the top of the box 3, storing the plug 2 in the box 3 and sealing the plug 2. After the baffle 61 is closed, the gear 62 and the tooth plate 64 mechanism remain in a self-locking state under the tension of the spring 65. It needs to be manually reset to be reopened, to prevent the live plug 2 from being accidentally exposed when the fault has not been eliminated. The baffle 61 has a warning sign on its surface, which warns the user that it should not be used. The warning sign is located on one side of the baffle 61 and can only be seen when the baffle 61 is lowered and seals the box 3. When the baffle 61 is placed vertically, the warning sign will not be visible, thus avoiding misunderstanding.

[0020] It also includes a stop 7 for limiting the toothed plate 64. The stop 7 includes a crossbar 71, a stop frame 72, a push plate 73, a spring 65 and a plate body 75. A crossbar 71 for engaging the stop frame 72 is provided between the two toothed plates 64. Two springs 65 are provided on the surface of the push plate 73 at the bottom of the stop frame 72. One end of each spring 65 is located on the surface of the plate body 75. The plate body 75 is installed on the inner wall of the box body 3. It is worth noting that the crossbar 71 is always engaged in the groove on the surface of the contact frame 72 to limit and prevent the two toothed plates 64 from detaching. At this time, the baffle 61 is in a vertical position and can be used normally. Only when the plug 2 leaks electricity will the cam 10 push the push plate 73, thereby driving the push plate 73 and the contact frame 72 to move. When the contact frame 72 moves to the point where it is no longer limited by the crossbar 71, the two toothed plates 64 are pushed up under the action of the two springs 65. The toothed plates 64 mesh with the gear 62, thereby driving the baffle 61 to rotate, sealing the top of the box 3 and protecting the plug 2 inside the box 3. When the contact frame 72 moves, it will drive the push plate 73 to squeeze the two springs 65. The function of the springs 65 is to restore the push plate 73.

[0021] The box 3 is equipped with a dual-axis motor 8 that is electrically connected to the metal plate 5. Both ends of the dual-axis battery are equipped with output rods 9. One end of the output rod 9 is rotatably mounted on the inner wall of the box 3. Both output rods 9 are equipped with cams 10 that cooperate with the push plate 73. It should be noted that, since the conductive ring 4 on the surface of plug 2 is attached to the metal plate 5, and the metal plate 5 is electrically connected to the dual-axis motor 8 through wires, when plug 2 leaks current, the dual-axis motor 8 drives the two output rods 9 to rotate, which in turn drives the cam 10 on the surface of the output rod 9 to rotate. The rotation of the cam 10 will squeeze the push plate 73, thereby continuously pushing the push plate 73 to move. When the cam 10 rotates and pushes the push plate 73 to move for the first time, the abutment frame 72 does not limit the crossbar 71. Under the action of the two springs 65, the two toothed plates 64 are pushed out, so that the baffle 61 rotates to block the plug 2 inside the box 3. Then, as the abutment frame 72 moves continuously, it will not touch the crossbar 71, but will only drive the push plate 73 to move continuously.

[0022] A bell 11 is installed at the bottom of the push plate 73 via two cables, and a reserved slot 12 for the movement of the two bells 11 is provided at the bottom of the box body 3. Specifically, the push plate 73 is pressed and moved by the cam 10 and reset under the pressure of the spring 65, realizing the reciprocating motion of the push plate 73. A bell 11 is installed at the bottom of the push plate 73 by a cable, so the bell 11 is driven to swing continuously to sound an alarm. The cable pulls the bell 11 at the bottom of the box 3 to shake violently and emit a high-frequency sound to remind the surrounding people to move away immediately.

[0023] Guide rods 13 are fixedly installed at the bottom of both toothed plates 64. The lower end of the guide rods 13 passes through the bottom of the box 3 and extends out. The surface of the guide rods 13 is movably connected to the inside of the spring 65. The guide rod 13 is vertically fixed to the bottom of the toothed plate 64, extends through the bottom of the box 3, and slides with the inner ring of the spring 65 to constrain the movement trajectory of the toothed plate 64, ensuring that the vertical up and down movement is free from sway. The spring 65 is positioned as a reference to prevent twisting during compression or release.

[0024] The surface of plug 2 is provided with an insulating layer 14, and the surface of the insulating layer 14 is provided with an insulating handle 15; The charging pile plug 2 adopts a dual protection structure of "insulation layer 14 and insulation handle 15". The insulation layer 14 is made of silicone or EPDM material to wrap the conductor of plug 2, with a withstand voltage of ≥10kV, ensuring that even if the internal circuitry ages, there will be no leakage current. The insulation handle 15 is made of ABS engineering plastic, which completely isolates the charge from the part that comes into direct contact with the human body. The dual protection complies with the IEC 60364-7-712 standard.

[0025] One side of the baffle 61 is integrally machined with a protective plate 16; The protective plate 16 is located on one side of the baffle 61. When the baffle 61 is rotated down to cover the top of the box 3, the protective plate 16 can cover the opening on one side of the box 3. On the side of the baffle 61 away from the protective plate 16, there is a warning sign that the user should not use the box. This warning sign is located on one side of the baffle 61 and can only be observed when the baffle 61 is lowered to seal the box 3. When the baffle 61 is placed vertically, the warning sign will not be visible. Baffle 61 is raised (usable state): The warning signs are completely hidden to avoid interfering with normal use; Baffle 61 closed (fault condition): Fluorescent red / black stripe warning signs are automatically displayed, conforming to ISO 3864-1 hazard labeling standard.

[0026] Both sides of the conductive ring 4 are integrally machined with limiting rings 17. The two limiting rings 17 are used to limit the plug 2 to the surface of the metal plate 5. The metal plate 5 is located between the two limiting rings 17. Both limiting rings 17 are made of conductive material. In addition to being attached to the metal plate 5 for conducting electricity, they also limit the plug 2 to the metal plate 5.

[0027] This device has a box 3 on one side of the charging pile body 1 for storing the plug 2. Since the conductive ring 4 on the surface of the plug 2 is attached to the metal plate 5, and the metal plate 5 is electrically connected to the dual-axis motor 8 through wires, when the plug 2 leaks current, the dual-axis motor 8 drives the two output rods 9 to rotate, which in turn drives the cam 10 on the surface of the output rod 9 to rotate. The rotation of the cam 10 will squeeze the push plate 73, thereby continuously pushing the push plate 73 to move. When the cam 10 rotates for the first time and pushes the push plate 73 to move, the contact frame 72 does not limit the crossbar 71, and the two springs 65 act as... When the two toothed plates 64 are pushed out, the baffle 61 rotates to block the plug 2 inside the box 3. Then, as the contact frame 72 moves continuously, it will not hit the crossbar 71, but will only drive the push plate 73 to move continuously. The push plate 73 is pressed and moved by the cam 10 and reset under the pressure of the spring 65, realizing the reciprocating motion of the push plate 73. The bottom of the push plate 73 is equipped with a bell 11 through a cable, so the bell 11 is driven to swing continuously to sound an alarm. The cable pulls the bell 11 at the bottom of the box 3 to shake violently and emit a high-frequency sound to remind the surrounding people to move away immediately.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
