[0006] A retracting structure, which is arranged on the charging gun handle and is used to control the plug to retract;

[0007] The telescopic structure includes a first cavity and a second cavity, the first cavity and the second cavity are arranged inside the charging gun handle, the first cavity is sleeved with a first spring, the second cavity is sleeved with a movable rod, the bottom end of the movable rod is connected with a clamping block, the outer surface of the movable rod is sleeved with a second spring, the top of the movable rod is sleeved with a fixed shaft, a fixing frame is installed on the top of the charging gun handle, a pressing piece is hinged on the top of the fixing frame, and a sliding groove is opened on one side of the pressing piece;

[0008] An extension member, which is disposed on the charging gun handle and is used to control the extension of the plug;

[0009] Among them, the extension component includes a first sleeve and a second sleeve, both of which are arranged inside the charging gun handle, a pressure rod is sleeved inside the first sleeve, and the end of the pressure rod passes through the charging gun handle. A round tube is connected between the first sleeve and the second sleeve, and a support rod is sleeved inside the second sleeve.

[0010] Preferably, the second spring is elastically supported between the second cavity and the block.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figures 1 to 3 As shown, the utility model provides a telescopic charging plug structure, including a charging gun handle 1 and a plug 3, and also includes:

[0023] A retracting structure, which is arranged on the charging gun handle 1 and is used to control the plug 3 to retract;

[0024] The telescopic structure includes a first cavity 2 and a second cavity 5, which are arranged inside the charging gun handle 1. The first spring 4 is sleeved inside the first cavity 2, and the movable rod 6 is sleeved inside the second cavity 5. The bottom end of the movable rod 6 is connected to a clamping block 7, and the outer surface of the movable rod 6 is sleeved with a second spring 8. The top of the movable rod 6 is sleeved with a fixed shaft 9. A fixing frame 10 is installed on the top of the charging gun handle 1, and a pressing piece 11 is hinged on the top of the fixing frame 10, and a sliding groove 12 is opened on one side of the pressing piece 11.

[0025] An extension member, which is disposed on the charging gun handle 1 and is used to control the plug 3 to extend;

[0026] Among them, the extension component includes a first sleeve 14 and a second sleeve 15, both of which are arranged inside the charging gun handle 1, and a pressure rod 13 is sleeved inside the first sleeve 14, and the end of the pressure rod 13 passes through the charging gun handle 1. A round tube 16 is connected between the first sleeve 14 and the second sleeve 15, and a support rod 17 is sleeved inside the second sleeve 15.

[0027] Through the cooperation between the pressing piece 11 and the fixing frame 10, when the pressing piece 11 rotates along the inner side of the fixing frame 10, it will drive the slide groove 12 to squeeze the fixed shaft 9, so that the movable rod 6 will move upward along the inner side of the second cavity 5 and drive the block 7, thereby driving the block 7 to separate from the plug 3. At this time, since the first spring 4 is in a compressed state, it will apply an elastic force to the plug 3, thereby driving the plug 3 to shrink along the inside of the first cavity 2, so as to facilitate its direct removal from the car charging socket.

[0028] The second spring 8 is elastically supported between the second cavity 5 and the clamping block 7 .

[0029] The design of the second spring 8 allows the block 7 to have good elastic reset performance. At this time, since the second spring 8 is in a compressed state, an elastic force is applied to the block 7, so that the block 7 can limit the plug 3.

[0030] One side of the clamping block 7 is provided with a chamfer, and the clamping block 7 is movably clamped with the plug 3 .

[0031] Through the chamfer provided on one side of the clamping block 7 , when the plug 3 is pressed against the chamfer of the clamping block 7 , the movable rod 6 will be driven to move upwards through the second spring 8 .

[0032] The fixed shaft 9 is slidably matched with the slide groove 12 , and the interior of the second sleeve 15 is filled with hydraulic oil.

[0033] Through the cooperation between the fixed shaft 9 and the slide groove 12, when the pressing member 11 rotates along the top of the fixing frame 10, the fixed shaft 9 will be squeezed through the slide groove 12 and the movable rod 6 will be driven to move upward, thereby driving the block 7 to separate from the plug 3.

[0034] The first spring 4 is elastically supported between the first cavity 2 and the plug 3 , and the end of the support rod 17 is in contact with the plug 3 .

[0035] The design of the first spring 4 enables the plug 3 to have good elastic reset performance. At this time, since the first spring 4 is in a compressed state, an elastic force is applied to the plug 3 to facilitate the plug 3 to retract into the first cavity 2.

[0036] The plug 3 is sleeved with the first cavity 2 , and the plug 3 is connected to the charging gun handle 1 through a line.

[0037] Through the cooperation between the plug 3 and the first cavity 2, the plug 3 can be extended and retracted along the inside of the first cavity 2. Before the plug 3 is pulled out, the plug 3 can be controlled to be extended and retracted to avoid shaking and prevent the pins inside it from loosening.

[0038] The working principle and use process of this utility model:

[0039] When the plug 3 is inserted into the car charging socket, the pressure rod 13 will be squeezed, so that the hydraulic oil inside the first sleeve 14 will enter the second sleeve 15 through the round tube 16, so that the hydraulic oil inside the second sleeve 15 will squeeze the support rod 17, so that the support rod 17 will squeeze the plug 3 and insert it into the car charging socket. When the plug 3 needs to be unplugged, the user can press the pressing piece 11. When the pressing piece 11 rotates along the inner side of the fixing frame 10, it will drive the slide groove 12 to squeeze the fixed shaft 9, so that the movable rod 6 will move upward along the inner side of the second cavity 5 and drive the block 7, so that the block 7 can be driven to separate from the plug 3. At this time, since the first spring 4 is in a compressed state, it will apply an elastic force to the plug 3, so that the plug 3 can be driven to shrink along the inside of the first cavity 2, so that it is convenient to directly pull it out from the car charging socket.
