Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicles, and in particular to a method for using a European standard charging socket. Background Art

[0002] With the development of the times, the technology of new energy vehicles is becoming more and more mature. New energy vehicles are highly praised by the society because of their pollution-free emissions. Most of the existing new energy vehicles are powered by electricity and charged by charging piles. The charging piles can be fixed in the parking lot of the community or in the charging station. The input end of the charging pile is connected to the AC power grid, and a charging gun is installed at the output end. A charging socket is provided on the body of the vehicle. Insert the charging gun into the charging socket to charge the new energy vehicle.

[0003] The charging socket is an important accessory on electric vehicles. At present, the charging socket of electric vehicles is generally installed on the body of the electric vehicle. A dust cover is provided on the outside of the charging socket. When the electric vehicle needs to be charged, the dust cover is opened and the charging socket is exposed to the outside world. The conductive battery cells in the charging socket are also exposed to the outside world. There is generally no anti-electric shock component inside the charging socket. When people plug and unplug the charging plug, if the operation is improper, they are very likely to touch the charged conductive battery cells, which may cause electric shock accidents. Summary of the invention

[0004] The purpose of the present invention is to solve the problems existing in the existing new energy vehicle charging technology and to provide a method for using a new type of European standard charging socket with a protective door to prevent electric shock.

[0005] The objective of the present invention is achieved in this way. A new type of European standard charging socket with a protective door to prevent electric shock comprises a charging plug, a charging gun, a socket electromagnetic lock, an outer shell, an inner shell, a charging interface, and an anti-electric shock protection door assembly; the outer shell is provided with a dust cover mounting assembly, a positioning protrusion and a limit locking groove; the dust cover mounting assembly comprises a dust cover and a dust cover opening; the inner shell is provided with a spring limit assembly, a spring limit locking assembly, an inner slide rail, an outer slide rail, a limit reinforcement rib, a limit guide column and a spring limit flange; the anti-electric shock protection door assembly comprises an anti-electric shock protection door panel, a sliding groove, a rotating groove, a muzzle groove, and a limit protrusion.

[0006] The spring limit assembly includes an external limit slider and an internal limit slider, the external limit slider includes a fixed slot, an upper inclined surface and a lower inclined surface, and a limit spring is arranged at the connection between the external limit slider and the internal limit slider; the internal limit slider includes an inner slide groove, an outer slide groove, a limit slide groove and a sliding guide column; the spring limit locking assembly includes a locking buckle, a locking groove, a limit locking spring, an arc surface, a locking inclined surface and a locking sliding guide column.

[0007] A method for using a novel European standard charging socket with a protective door to prevent electric shock, the method comprising the following steps;

[0008] Step 1: Fix the charging socket, with the dust cover on the charging socket in the closed state, and open the dust cover.

[0009] Step 2: After opening the dust cover, slowly push the charging gun along the charging port until it fits into the muzzle groove on the anti-electric shock protection door panel.

[0010] Step three: The anti-electric shock protection door panel is closed, and the limiting protrusion at the bottom of the anti-electric shock protection door panel is fixed in the locking groove of the locking buckle.

[0011] Step 4: While slowly pushing the charging gun in, the bottom of the front end of the charging gun will contact the locking bevel on the locking buckle. Under the action of the charging gun, the locking bevel will cause the limit locking spring at the bottom of the locking buckle to elastically deform and move downward, causing the limit protrusion at the bottom of the anti-electric shock protection door panel to separate from the locking groove of the locking buckle. The anti-electric shock protection door panel is initially opened, and the locking buckle returns to its original state.

[0012] Step 5: Under the action of the locking bevel on the charging gun, the charging gun will tilt upward to a certain extent, slightly lifting the charging gun so that the front end of the charging gun contacts the lower bevel of the external limit slider.

[0013] Step 6: Lift the charging gun, and the front end of the charging gun will slide on the lower slope until the front end of the charging gun is fixed between the upper slope and the lower slope.

[0014] Step 7: Continue to lift the charging gun, the external limit module slides upward, driving the internal limit slider to move upward. During the sliding process of the spring limit component, the anti-electric shock protection door is driven to open.

[0015] Step 8: The spring limit assembly continues to slide until the limit groove on the built-in limit slider fits with the limit guide post on the limit reinforcement rib, at which time the spring limit assembly stops sliding.

[0016] Step 9: The spring limit assembly stops sliding, the anti-electric shock protection door is fully opened, and the charging gun is pushed into the charging port.

[0017] Step 10: Insert the charging gun into the charging port to complete the charging operation. The socket electromagnetic lock will lock the charging gun. The spring limit assembly cannot slide down because the charging gun is locked, so the anti-electric shock protection door panel is fixed.

[0018] Step 11: After charging is completed, slowly pull out the charging gun and slide the spring limit assembly downward until the outer wall of the inner groove of the built-in limit slider fits against the top of the charging port.

[0019] Step 12: When pulling out the charging gun, the limit locking spring at the bottom of the locking buckle will elastically deform and slide downward.

[0020] Step 13: After the charging gun is completely pulled out, the anti-electric shock protection door panel is closed, and the limiting protrusion at the bottom of the anti-electric shock protection door panel is fixed in the locking groove of the locking buckle.

[0021] As a further improvement of the present invention, in order to facilitate the functional linkage between the built-in limit slider and the anti-electric shock protection door assembly, the built-in limit slider slides upward, and the built-in limit slider drives the anti-electric shock protection door panel to open. The anti-electric shock protection door panel is rotated and arranged on the limit guide post. The sliding guide post slides out of the lower end limit groove and slides along the sliding groove on the anti-electric shock protection door panel. The inner slide groove of the built-in limit slider moves along the inner slide rail on the inner shell, and the outer slide groove on the built-in limit slider moves along the outer slide rail on the inner shell.

[0022] When the present invention is working, the charging socket is fixed on the wall and the dust cover on the charging socket is in a closed state. The dust cover on the charging socket is opened. At this time, the anti-electric shock protection door panel is locked in combination with the spring limit locking assembly. The anti-electric shock protection door panel is fixed in the card slot of the external limit sliding block. The limit protrusion at the bottom of the anti-electric shock protection door panel is fixed in the locking groove inside the locking buckle. The sliding guide column is fixed in the lower end limit groove of the sliding groove of the anti-electric shock protection door panel, which can effectively prevent the anti-electric shock protection door panel from being easily opened by humans.

[0023] The beneficial effect of the invention is that the invention avoids direct contact between the operator's limbs and the metal conductive parts of the charging socket through a method of using an anti-electric shock European standard charging socket, effectively prevents electric shock accidents, effectively improves the safety of the use of charging equipment, is easy to operate, and has wide applicability.

[0043] Step 4: While slowly pushing the charging gun in, the bottom of the front end of the charging gun will contact the locking bevel 39 on the locking buckle 35. Under the action of the charging gun, the locking bevel 39 will cause the limiting locking spring 37 at the bottom of the locking buckle 35 to elastically deform and move downward, so that the limiting protrusion 24 at the bottom of the anti-electric shock protection door panel 20 is separated from the locking groove 36 of the locking buckle 35, the anti-electric shock protection door panel 20 is initially opened, and the locking buckle 35 returns to its original state.

[0044] Step 5: Under the action of the locking bevel 39 on the charging gun, the charging gun will tilt upward to a certain extent, slightly lifting the charging gun so that the front end of the charging gun contacts the lower bevel 29 of the external limit slider 25 .

[0045] Step 6: Lift the charging gun, and the front end of the charging gun will slide on the lower inclined surface 29 until the front end of the charging gun is fixed between the upper inclined surface 28 and the lower inclined surface 29 .

[0046] Step 7: Continue to lift the charging gun, the external limit module slides upward, driving the internal limit slider 26 to move upward, and during the sliding process of the spring limit assembly 12, the anti-electric shock protection door panel 20 is driven to open.

[0047] Step 8: The spring limiting assembly 12 continues to slide until the limiting groove 33 on the built-in limiting slider 26 fits with the limiting guide post 17 on the limiting reinforcement rib 16, at which time the spring limiting assembly 12 stops sliding.
