Description

Technical Field

[0001] This utility model relates to the field of charging gun technology for new energy vehicles, specifically to a self-locking quick connector for new energy vehicles. Background Technology

[0002] When charging new energy vehicles, a charging gun on a charging station is required. To ensure a stable connection between the charging gun and the new energy vehicle or charging station, a locking component needs to be installed on the charging gun. To reduce the manufacturing cost of the charging gun, a spring-loaded locking mechanism is used. When the connector of the charging gun is connected to the socket on the new energy vehicle or charging station, the spring will pull the locking block on the locking tongue to automatically disengage into the slot on the socket, thereby achieving a self-locking effect on the connector. When it is necessary to remove the charging gun, simply press down on the locking tongue to make it tilt forward and separate from the slot on the socket, thus achieving a quick unlocking effect.

[0003] However, the locking tongue on most common charging guns on the market is installed on the outside of the charging gun. Since the charging guns are mostly exposed to the air, dust and rainwater can easily get into the connection between the locking tongue and the gun shell. The influence of pollutants can make it difficult for the spring to pull the locking tongue to fully reset, which in turn makes it impossible for the locking hole on the locking tongue to be fully inserted into the slot on the socket. This makes it difficult for the connector and the socket to be stably connected. In order to address the above situation, we will innovate the technology based on the existing self-locking quick connector for new energy vehicles. Utility Model Content

[0004] The purpose of this utility model is to provide a self-locking quick connector for new energy vehicles to solve the problems mentioned in the background art.

[0020] 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.

[0021] Please see Figures 1-4 A self-locking quick connector for new energy vehicles includes a charging gun 1. The top of the charging gun 1 has a groove that extends through the left side of the charging gun 1. A locking tongue 13 is placed in the groove. A protective cover 11 is fixedly installed on the top of the charging gun 1. A clearance cavity is opened at the bottom of the protective cover 11 and extends through the left side of the protective cover 11. The clearance cavity is connected to the groove. A clearance opening is opened through the right side of the clearance cavity. A flap 12 is placed inside the right side of the protective cover 11. A first through hole is opened through the front side of the flap 12. A second rotating shaft 121 is rotatably installed in the first through hole. The second rotating shaft 121 is fixedly installed in the clearance cavity. A torsion spring 122 is fixedly installed between the second rotating shaft 121 and the first through hole. The flap 12 is located to the left of the clearance opening. The left side of the protective cover 11 is flush with the left side of the housing of the charging gun 1.

[0022] A sealing gasket 126 is fixedly installed on the right side of the inner wall of the clearance cavity. The left side of the sealing gasket 126 is in contact with the right side of the flap 12. The torsion of the torsion spring 122 causes the flap 12 to be in contact with the sealing gasket 126, thereby sealing the clearance opening of the cover 11 through the flap 12. Through the cooperation of the cover 11 and the flap 12, external contaminants can be effectively prevented from contacting the gap between the lock tongue 13 and the charging gun 1, so that the spring 15 can pull the lock tongue 13 to fully reset, thereby ensuring the lock The locking effect of the tongue 13 on the connector is achieved by uniformly fixing two sets of support blocks 124 at the bottom of the flip plate 12. A third rotating shaft 123 is fixedly fixed between the two sets of support blocks 124. A roller 127 is rotatably sleeved on the outer ring of the third rotating shaft 123. A rubber sleeve 125 is fixedly installed on the outer wall of the roller 127. When the user holds the charging gun 1 and inserts his thumb through the avoidance opening of the cover 11 into the avoidance cavity, the thumb will push the flip plate 12 to flip to the left around the second rotating shaft 121. When the latch 13 comes into contact with the thumb, the flap 12 flips to the top of the thumb, at which point the roller 127 comes into contact with the thumb. The rubber sleeve 125 can improve the comfort of the thumb when it comes into contact with the roller 127. The front side of the latch 13 has a second through hole, and the first rotating shaft 14 is rotatably installed in the second through hole. The bottom right side of the latch 13 is fixedly installed with a spring 15. The bottom right side of the groove has an installation groove. When the thumb presses down on the latch 13, the latch 13 will flip around the center of the first rotating shaft 14 and press down on the spring 15, thereby causing the locking block on the latch 13 to move upward and separate from the slot on the socket of the new energy vehicle or charging pile. At this time, the connector of the charging gun 1 can be separated from the socket. Then, when the user's thumb is pulled out from the clearance opening, the roller 127 will roll on the surface of the thumb, thereby reducing the chance of the thumb being stuck by the flap 12 and improving the safety of use. The first rotating shaft 14 is fixedly installed in the groove, and the spring 15 is fixedly installed in the installation groove.

[0023] Working principle: When the user holds the charging gun 1 and inserts their thumb through the clearance opening of the cover 11 into the clearance cavity, the thumb pushes the flip plate 12 to rotate to the left around the second pivot 121. When the thumb contacts the locking tongue 13, the flip plate 12 rotates to the top of the thumb, at which point the roller 127 contacts the thumb. The rubber sleeve 125 improves the comfort of the thumb when contacting the roller 127. When the thumb presses down on the locking tongue 13, the locking tongue 13 rotates around the first pivot 14 and compresses the spring 15 downwards, causing the locking block on the locking tongue 13 to move upwards and separate from the slot on the socket of the new energy vehicle or charging pile. At this time, the connector of the charging gun 1 can be separated from the socket. Then, when the user's thumb is pulled out from the clearance opening, the roller 127 rolls on the surface of the thumb, thereby reducing the chance of the thumb being stuck by the flip plate 12, thus improving the safety of use. During separation, the torsion of the torsion spring 122 causes the flap 12 to fit against the sealing gasket 126, thereby sealing the clearance opening of the cover 11 through the flap 12. Through the cooperation of the cover 11 and the flap 12, external contaminants can be effectively prevented from contacting the gap between the locking tongue 13 and the charging gun 1, so that the spring 15 can pull the locking tongue 13 to fully reset, thus ensuring the locking effect of the locking tongue 13 on the connector. When the connector of the charging gun 1 is inserted into the slot on the socket of the new energy vehicle or charging pile, the spring 15 uses its own rebound force to drive the locking tongue 13 to reset, thereby driving the locking block on the locking tongue 13 to move downward and insert into the slot on the socket, thus realizing the self-locking of the connector. The working principle of the spring locking tongue assembly is now quite mature, so it will not be elaborated here. At this time, the left side of the housing of the charging gun 1 will fit against the socket, and since the left side of the cover 11 is flush with the left side of the housing of the charging gun 1, the left side of the cover 11 will also fit against the socket.
