Abstract
Description
Technical Field
[0001] This invention relates to a charging station with a replaceable charging gun. Background Technology
[0002] The charging gun is a key connecting component between an electric vehicle and the charging equipment. Its core function is to efficiently transmit electrical energy to the electric vehicle. Depending on the type of current entering the vehicle, charging guns are divided into two types: DC charging guns and AC charging guns. AC charging guns are mainly divided into three types: Type 1, Type 2, and GB / T, which can also be referred to as American standard, European standard, and Chinese standard. Currently, most charging piles on the market are directly connected to one of these types of charging guns, making it inconvenient to adjust and adapt the charging gun head according to the vehicle's plug type. Summary of the Invention

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0024] like Figures 1 to 7 As shown, the charging station with a replaceable charging gun includes a detachably connected station body 100 and a charging gun body 200. The lower end of the station body 100 is connected to a power cord 101 and a charging gun connection line 102. The end of the charging gun connection line 102 is provided with a male connector 1.
[0025] The male connector 1 includes an annular outer wall 11, an annular locking cavity 111 is provided on the inner side of the outer wall 11, and several positioning grooves 112 are also provided at intervals on the inner side of the outer wall 11, 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, the plug 12 includes a first pin cavity 121 and several second pin cavities 122, the second pin cavities 122 are arranged at intervals around the first pin cavity 121, the first pin cavity 121 is provided with a positive pin, and the second pin cavity 122 is provided with a negative pin.
[0026] A buckle 13 is provided on the outer wall 11. The buckle 13 includes a channel 131 that penetrates the outer wall 11. The channel 131 is annular and contains a ball bearing 132. The diameters at both ends of the channel 131 are smaller than the diameters of the ball bearing 132. The ball bearing 132 can be partially exposed in the channel 131 but cannot completely leave the channel 131. Furthermore, the diameter of the ball bearing 132 is greater than the length of the channel 131.
[0027] One end of the gun body 200 is provided with a charging gun head 201, and the other end is provided with a connecting female head 2; the connecting female head 2 includes a locking cavity wall 22 that cooperates with the locking cavity 111, and the outer side of the locking cavity wall 22 is provided with outwardly protruding positioning blocks 221 that cooperate with the positioning groove 112.
[0028] The inner side of the locking cavity wall 22 is provided with a first cavity 23 that mates with the plug 12. The first cavity 23 is provided with a first pin post 231 and a second pin post 232 that mate with the first pin cavity 121 and the second pin cavity 122. Both the first pin post 231 and the second pin post 232 are provided with pin holes.
[0029] The lower outer side of the locking cavity wall 22 is provided with a locking groove 222 that cooperates with the buckle 13. The locking groove 222 is located 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. 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 inner wall of the sliding sleeve 21 is provided with a protruding wall 211. When the sliding sleeve 21 is in the 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 located at the lower end of the locking groove 222.
[0030] The connection and locking method between the pile body 100 and the gun body 200 is as follows: First, align the positioning groove 112 of the male connector 1 with the positioning block 221 of the female connector 2, and push the female connector 2 into the male connector 1. When the ball 132 is aligned with the protruding wall 211, the protruding wall 211 pushes the ball 132 inward. Continue pushing inward until the ball 132 enters the locking groove 222. At this time, because the protruding wall 211 is pushing the ball 132, the ball 132 is locked in the locking groove 222, thereby achieving the locking of the male connector 1 and the female connector 2. When unlocking, slide the sliding sleeve 21 backward. The protruding wall 211 no longer pushes the ball 132, so the ball 132 can be pulled out of the locking groove 222 by external force, thereby separating the female connector 2 and the male connector 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 Chinese standard gun head; by connecting the male connector 1 and the female connector 2, a charging station can be connected to multiple standard gun heads, allowing users to change them according to their needs.
[0032] The charging pile of the present invention with a replaceable charging gun has a male connector 1 on the charging gun connection line 102 of the pile body 100 and a female connector 2 at one end of the gun body 200. The male connector 1 has a buckle 13 on its outer wall 11 and a locking cavity 111 on its inner side. The female connector 2 has a locking groove 222 on its locking cavity wall 22. The female connector 2 has a sliding sleeve 21 on its outermost side, and a protruding wall 211 at its lower end that is opposite to the locking groove 222. When engaged with the male connector 1, the protruding wall 211 pushes 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 pushes the ball 132. 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 Chinese standard gun head. Through the mutual connection of the male connector 1 and the female connector 2, a charging pile can be connected to gun heads of multiple standards.
