[0023] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0024] like Figures 1 to 7 As shown, the charging pile with a replaceable charging gun includes a detachably connected pile body 100 and a gun body 200. The lower end of the pile body 100 is connected to a power line 101 and a charging gun connecting line 102. The end of the charging gun connecting line 102 is provided with a connecting male connector 1.

[0025] The connecting male plug 1 includes an annular outer wall 11, and an annular locking cavity 111 is provided on the inner side of the outer wall 11. A plurality of positioning grooves 112 are also provided on the inner side of the outer wall 11 at intervals, and the positioning grooves 112 are connected to the locking cavity 111; a plug 12 is provided on the inner side of the locking cavity 111, and the plug 12 includes a first pin cavity 121 and a plurality of second pin cavities 122, and the second pin cavities 122 are arranged at intervals around the first pin cavity 121, and a positive pin is provided inside the first pin cavity 121, and a negative pin is provided inside the second pin cavity 122.

[0026] A buckle 13 is provided on the outer wall 11, and the buckle 13 includes a channel 131 that passes through the outer wall 11. The channel 131 is annular and has a ball 132 provided inside. The diameters at both ends of the channel 131 are smaller than the diameter of the ball 132. The ball 132 can be partially exposed from the channel 131 but cannot completely leave the channel 131; and the diameter of the ball 132 is greater than the length of the channel 131.

[0027] A charging gun head 201 is provided at one end of the gun body 200, and a connecting female head 2 is provided at the other end; the connecting female head 2 includes a locking cavity wall 22 that cooperates with the locking cavity 111, and a positioning block 221 that protrudes outward and cooperates with the positioning groove 112 is provided at an interval on the outer side of the locking cavity wall 22.

[0028] A first cavity 23 that cooperates with the plug 12 is provided on the inner side of the locking cavity wall 22, and a first pin column 131 and a second pin column 232 that cooperate with the first pin cavity 121 and the second pin cavity 122 are provided inside the first cavity 23. Pin holes are provided inside the first pin column 131 and the second pin column 232.

[0029] The lower end of the outer side of the locking cavity wall 22 is provided with a circle of locking grooves 222 that cooperate with the buckle 13, and the locking grooves 222 are provided at the lower end of the positioning block 221; the outermost side of the connecting female head 2 is provided with a sliding sleeve 21, and a second cavity 24 that cooperates with the outer wall 11 is provided between the sliding sleeve 21 and the locking cavity wall 22; the sliding sleeve 21 can slide backward relative to the locking cavity wall 22; the lower end of the inner wall of the sliding sleeve 21 is provided with a protruding wall 211. When the sliding sleeve 21 is in a normal state, the protruding wall 211 is opposite to the locking groove 222. When the sliding sleeve 21 is slid backward, the protruding wall 211 is relatively located at the lower end of the locking groove 222.

[0030] The connection and locking method of the pile body 100 and the gun body 200 is as follows: first, the positioning groove 112 of the connecting male head 1 and the positioning block 221 of the connecting female head 2 are aligned, and the connecting female head 2 is pushed into the connecting male head 1. When the ball 132 is aligned with the protruding wall 211, the protruding wall 211 pushes the ball 132 inward. Continuing to push inward, the ball 132 enters the locking groove 222. At this time, since the protruding wall 211 forces the ball 132, the ball 132 is locked in the locking groove 222, thereby achieving the locking of the connecting male head 1 and the connecting female head 2; when unlocking, the sliding sleeve 21 is slid backward, and the protruding wall 211 no longer forces the ball 132. Therefore, the ball 132 can be pulled out of the locking groove 222 by external force, thereby separating the connecting female head 2 and the connecting male head 1.

[0031] The gun head 201 of the gun body 200 can be a European standard gun head, an American standard gun head, or a national standard gun head; by connecting the male head 1 and the female head 2 in coordination with each other, a charging pile can be connected to gun heads of multiple standards, allowing users to replace them according to their needs.

[0032] The charging pile of the replaceable charging gun of the present invention is provided with a connecting male head 1 on the charging gun connecting line 102 of the pile body 100, and a connecting female head 2 is provided at one end of the gun body 200. A buckle 13 is provided on the outer wall 11 of the connecting male head 1, a locking cavity 111 is provided on the inner side of the outer wall 11, a locking groove 222 is provided on the locking cavity wall 22 of the connecting female head 2, a sliding sleeve 21 is provided on the outermost side of the connecting female head 2, and a protruding wall 211 opposite to the locking groove 222 is provided at the lower end of the sliding sleeve 21. When matched with the connecting male head 1, the protruding wall 211 forces the ball 132 of the buckle 13 into the locking groove 222 to achieve locking; when unlocking, the sliding sleeve 21 is slid backward, and the protruding wall 211 no longer forces the ball 132, and the ball 132 can be pulled out of the locking groove 222 by external force. The connection method is simple, and the gun head 201 can be a European standard gun head, an American standard gun head, or a national standard gun head; through the mutual cooperation connection of the connecting male head 1 and the connecting female head 2, one charging pile can be connected to gun heads of multiple standards.
