The charging pile and the construction method of charging gun for new energy electric vehicle
In the existing technology, the power connection between the charging pile and the electric vehicle is realized through the charging gun. Generally, the gun head of the charging gun is designed with a handle for holding and pinching. Therefore, the gun head of the whole charging gun is large in volume and heavy in weight. The charging gun is inserted into the fixed slot of the charging pile head and is supported by the gun head of the charging gun, so the burden of the gun head of the charging gun is relatively large.
In addition, if the fixed part of the charging gun head is firmly inserted into the gun head fixing groove, it is easy to cause the gun head to fall to the ground, and the charging gun head has poor sealing performance and poor water resistance after being inserted into the gun head fixing groove.
In addition, if someone steps on or pulls the connecting wire at the interface between the charging gun and the connecting wire, the end of the connection will be cracked. This is the most vulnerable place to be damaged, regardless of any charging line.
Technical implementation elements:
The technical problem to be solved by the utility model is to provide a smaller volume of the charge gun head, separate the handle from the charge gun head, simplify the structure of the charging gun, increase the connection strength between the wire rod and the charging gun, and have a sliding sleeve to reduce the pressure of the charging gun, increase the sealing between the charging gun and the charging pile, and effectively prevent the charging gun from being on the charging pile The problem of falling.
The utility model is realized by the following technical scheme: a charging pile and a charging gun structure of a new energy electric vehicle, including a charging pile and a charging gun, two sides of the charging gun are respectively provided with a sliding sleeve, the two ends of the sliding sleeve are opened, the charging gun penetrates through the sliding sleeve and extends out of the outer end, the tail end of the sliding sleeve is directly opposite to the two sliding grooves, and the corresponding sliding blocks are arranged on the two sliding grooves The sleeve slides in the chute through the sliding block, and a protection bracket is installed at the tail of the charging gun, and the connecting line of the charging gun is clamped into the protection bracket and forms a bending section.
As an optimization, a limit groove is arranged on both sides of the inner wall of the positioning groove, which is perpendicular to the horizontal plane, and the two ends of the sliding sleeve are respectively provided with a limit block, and the two limit blocks are respectively clamped into the limit groove from top to bottom.
As a preferred method, one end of the protection bracket is provided with two fixing sets, the outer end of the protection bracket extends out and is provided with a fixing clip, the connecting line of the charging gun is clamped in the fixing clip, and the bending section is formed between the protection bracket and the fixing clip.
Preferably, the top of the protection bracket is provided with a handle for holding.
The beneficial effects of the utility model are: the utility model has simple structure, can protect the plug of the charging gun through the sliding sleeve, and complete the positioning of the charging gun through the sliding sleeve. The sliding sleeve can effectively increase the sealing property of the plug of the charging gun, increase the waterproof property, and effectively prevent the charging gun from slipping off the charging pile. In addition, the utility model has a protective bracket to better protect the wire rod and charging The connection end of the electric gun increases the service life.
The codes are as follows: 1 is charging pile, 2 is charging gun socket, 3 is limit block, 5 is handle, 7 is protection support, 8 is fixing clamp, 9 is connecting wire, 11 is bending section, 12 is fixing sleeve, 13 is sliding sleeve, 14 is charging gun, 15 is sliding block, 16 is sliding groove.
Specific implementation mode
As shown in Figure 1, the charging pile and charging gun structure of the new energy electric vehicle include charging pile 1 and charging gun 14, two sides of charging gun 14 are provided with a sliding sleeve 16, the head of charging gun 14 is equipped with a sliding sleeve 13, both ends of the sliding sleeve 13 are opened, the charging gun 14 extends out of the outer end through the sliding sleeve 13, and the tail end of the sliding sleeve 13 is directly opposite to the two sliding grooves 16, and the sliding sleeve 13 is provided with corresponding sliding blocks 15 through the sliding sleeve 15 A protection bracket 7 is installed at the tail of the charging gun 14. The connecting line 9 of the charging gun 14 is clamped into the protection bracket 7 and forms a bending section 11.
In this embodiment, the top of the charging pile is arranged in a positioning groove from top to bottom, the positioning groove is directly opposite to the charging gun socket 2 of the charging pile at the bottom, the socket of the charging gun 14 is arranged on the bottom surface of the positioning groove, the sliding sleeve 13 slides into the positioning groove from top to bottom, a limit groove is set on both sides of the inner wall of the positioning groove, the limit groove is vertical to the horizontal plane, and the two ends of the sliding sleeve 13 are respectively provided with a limit block 3, The two limit blocks 3 are movably clamped into the limit slot from top to bottom. The charging gun 14 is installed from the top of the charging pile 1 through the sliding sleeve 13, and then the charging gun retracted in the sliding sleeve is inserted into the socket of the charging gun. The sliding sleeve is used as a sealing element to cover the outside of the charging gun to ensure the sealing and prevent the charging gun from charging The gun socket slips to prevent the charging gun from being fully inserted into the charging gun socket.
In this embodiment, one end of the protection bracket 7 is provided with two fixing sets 12, the outer end of the protection bracket 7 extends out and is provided with a fixing clip 8, the connecting line of the charging gun 14 is clamped in the fixing clip 8, the bending section 11 is formed between the protection bracket 7 and the fixing clip 8, and the top of the protection bracket is provided with a handle 5 for holding and pinching, The buffer can be completed through the bending section, which can effectively protect the connecting line between the charging gun and the charging gun, and increase the service life; in addition, the handle is separated from the charging gun, which can effectively reduce the weight of the charging gun, damage the better protection bracket, and reduce the cost.
The utility model has the following beneficial effects: the utility model has simple structure, can protect the plug of the charging gun through the sliding sleeve, and complete the positioning of the charging gun through the sliding sleeve. The sliding sleeve can effectively increase the sealing of the plug of the charging gun, increase the waterproof property, and effectively prevent the charging gun from slipping off the charging pile, and has a protective bracket, which is better
