Description

Technical Field

[0001] The utility model relates to the field of charging equipment, in particular to an anti-leakage protection device for a new energy vehicle charging station. Background Art

[0002] A charging pile, also known as an electric vehicle charging station or electric vehicle power supply equipment, is a device that provides electrical energy to electric vehicles, enabling them to store enough electricity to support their operation. It consists of a pile body, an electrical module, a metering module and other parts, and generally has functions such as electricity metering, billing, communication, and control.

[0003] Floor-mounted charging piles are also more common in large outdoor public places. A large number of floor-mounted charging piles have been built, which are directly connected to the three-phase AC power grid via the input end. Under severe weather conditions and improper human operation, electric leakage accidents are prone to occur, posing a great threat to the safety of people's lives and property.

[0004] The charging gun and power cord are exposed to the sun and wind for a long time, which will cause rainwater to enter the charging pile, causing leakage, posing a safety hazard to personnel. When leakage occurs, the power is often not cut off in time, which may lead to more serious situations such as fire. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a new energy vehicle charging station anti-leakage protection device to solve the technical problem that leakage of general charging piles may cause safety hazards.

[0006] The cam is secured to the interior of the charging station with a secure lock and secured to the interior of the charging station with a secure lock.

[0007] The utility model is further configured such that one end of the positioning block is connected to a pulley, and a fixing groove matching the pulley is provided inside the charging pile.

[0008] The present invention is further configured such that a contact piece is provided on one side of the socket, and a contact head is provided on one side of the fixing seat.

[0009] The present invention is further configured such that a water baffle is provided on the side wall of the charging pile above the socket.

[0010] The present invention is further configured such that a slot is provided inside the socket, and the shape and size of the slot match the shape and size of the plug.

[0011] The utility model is further configured such that one end of the fixing seat is connected to a guide plate, and a guide groove is provided on a side wall of the socket.

[0012] To sum up, the utility model mainly has the following beneficial effects: the utility model can prevent leakage caused by misoperation. When the plug is inserted into the socket, the plug will squeeze the blocking block inward. At this time, the connecting rod will move inward and cause the rotating plate to rotate. While rotating, the positioning block will be pulled inward to unlock the socket. At this time, the socket can move inward with the plug until the socket is stuck by the blocking block and power is supplied. When the plug may leak electricity, the temperature at the position of the plug and the socket will rise linearly. At this time, the mercury expands due to heat, pushing the push plate forward. When the push plate contacts the movable block and squeezes the movable block inward, the movable block pulls the connecting strip and the blocking block inward, and the movable block unlocks the socket. The socket pops up under the action of the first spring, and the power supply is released, which can effectively prevent the occurrence of combustion caused by continued power supply.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0021] A new energy vehicle charging station anti-leakage protection device, such as Figure 1-6 As shown, it includes a charging pile 1 and a fixing seat 3, the fixing seat 3 is installed inside the charging pile 1, the side wall of the charging pile 1 is movably provided with a socket 2, the inside of the socket 2 is provided with a groove 7, the inner bottom wall of the groove 7 is rotatably connected with a rotating plate 6, one side of the rotating plate 6 is rotatably provided with a connecting rod 5, one end of the connecting rod 5 is connected with a card block 4, the inside of the socket 2 is movably provided with a positioning block 8, the side wall of the positioning block 8 is provided with a through groove, one end of the rotating plate 6 passes through the through groove and is cross-arranged with the positioning block 8. When the plug is used for charging operation, the ground wire end of the plug is first inserted into the socket 2, and the ground wire end will squeeze the card block 4, causing the card block 4 to move inward. At this time, the connecting rod 5 moves inward accordingly and causes the rotating plate 6 to rotate. While rotating, the positioning block 8 is pulled inward to unlock the socket 2, so that the socket 2 can move inward with the plug.

[0022] A positioning seat 10 is provided on one side of the fixing seat 3, and a movable block 11 is provided inside the positioning seat 10. A first spring 12 is connected between the movable block 11 and the inner wall of the fixing seat 3. The outer wall of the movable block 11 is rotatably connected to a connecting strip 14, and one end of the connecting strip 14 is rotatably connected to an insert block 13. A slot 15 is provided inside the socket 2, and the shape and size of the slot 15 match the shape and size of the insert block 13. A second spring 21 is provided between the fixing seat 3 and the socket 2, and a fixing sleeve 16 is provided in the internal mounting groove of the socket 2. The fixing sleeve 1 6 is filled with mercury, and a push plate 17 is provided at one end of the fixing sleeve 16. When the socket 2 moves inward with the plug, the inclined portion of the plug block 13 will contact the side wall of the mounting groove and be squeezed into the interior of the positioning seat 10. At this time, the plug block 13 will push the connecting strip 14 and the movable block 11 to move inward and squeeze the first spring 12. When the plug block 13 moves to the position of the slot 15, the plug block 13 is no longer squeezed. Under the action of the first spring 12, the plug block 13 is inserted into the slot 15, completing the fixation of the positioning seat 10 and the socket 2.

[0023] A contact piece 19 is provided on one side of the socket 2, and a contact head 18 is provided on one side of the fixing seat 3. When the positioning seat 10 and the socket 2 are fixed, the contact piece 19 contacts the contact head 18. At this time, the charging pile 1 supplies power to the socket 2 and the plug. This power supply method is the power supply method in the prior art, so it is not described in detail.

[0024] When the plug leaks during charging, a large amount of heat is generated during the leakage process, and high temperature may also be generated when the plug is not working properly. At this time, the heat will be conducted to the fixed sleeve 16, and the mercury inside the fixed sleeve 16 will expand due to the heat, pushing the push plate 17 forward. The fixed sleeve 16 is in the shape of a telescopic corrugated shape. Therefore, after the mercury expands, the push plate 17 will move forward with the movement of the fixed sleeve 16 until the push plate 17 contacts the movable block 11 and pushes the movable block 11 to move inward and squeeze the first spring 12. When the movable block 11 moves inward, it will synchronously drive the connecting strip 14 and the plug block 13 to move synchronously. At this time, the plug block 13 is disengaged from the slot 15, releasing the fixation of the positioning seat 10 and the socket 2. At the same time as the fixation is released, it will pop outward under the action of the second spring 21. At this time, the contact piece 19 is no longer in contact with the contact 18, and charging stops, effectively preventing the safety hazard caused by continuing charging in the case of leakage and malfunction.

[0025] A water baffle 20 is provided on the side wall of the charging pile 1 above the socket 2 , and the water baffle 20 can effectively protect the plug.

[0026] One end of the fixing seat 3 is connected to a guide plate, and a guide groove is provided on the side wall of the socket 2. The guide plate and the guide groove can guide the movement of the socket 2.

[0027] One end of the positioning block 8 is connected to a pulley 9, and a fixing groove that matches the pulley 9 is opened inside the charging pile 1. The pulley 9 is inserted into the fixing groove to fix the socket 2 and the charging pile 1, and the pulley 9 can assist in movement.

[0028] Furthermore, some charging plugs can use other types of plugs other than three-pin plugs, and they only need to be able to be inserted into the hole inside the socket 2 to release the fixation of the socket 2.
