[0044] To match the mounting plate on the lower housing, such as Figure 2 As shown, the upper end cover 132 is provided with a U-shaped opening matching the mounting plate 1312 .

[0045] To adapt the charging plug, such as Figure 2 As shown, the mounting boss 1321 of this embodiment includes a boss body 13211, a first extension body 13212 and a second extension body 13213. The first extension body 13212 and the second extension body 13213 are symmetrically arranged on both sides of the boss body 13211 and extend in the length direction of the upper end cover 132.

[0050] In order to facilitate the charging plug to press the lock button, the angle between the first surface of the lock button 142 and the first surface of the boss body 13211 is an acute angle. The first surface of the lock button 142 is the surface of the lock button 142 away from the slider 141, and the first surface of the boss body 13211 is the surface of the boss body 13211 away from the lower shell 131.

[0051] One end of the elastic member 143 is inserted into the slider 141, and the other end is fixed to the lower housing 131. In this embodiment, the elastic member 143 may be a spring. When the locking mechanism 14 is in the initial state, the elastic member 143 does not undergo elastic deformation.

[0052] The stopper 144 is disposed on the side of the slider 141 facing the mounting plate 1312 and is inserted into the limiting hole 1314 , so that the sliding stroke of the slider 141 is limited by the cooperation between the stopper 144 and the limiting hole 1314 .

[0053] In order to ensure smooth conduction between the pin of the charging plug and the wire, in this embodiment, a conductive mechanism 15 is provided on the lower shell 131, and the conductive mechanism 15 corresponds to the mounting boss 1321, wherein one end of the conductive mechanism 15 is connected to the wire extending from the other connection end, and the other end of the conductive mechanism 15 is in contact and extrusion with the charging plug 2 inserted into the mounting boss 1321.

[0054] Specifically, in order to make the conductive mechanism simple in structure and easy to conduct electricity, the conductive mechanism 15 includes at least two conductive bodies 151 and at least two elastic conductive sheets 152. Figure 3 and Figure 5 As shown, this embodiment comprises two conductive bodies 151 and two elastic conductive sheets 152. One end of the conductive body 151 is used to connect with the wire, and the other end of the conductive body 151 is provided with a metal sheet extending toward the mounting boss 1321, on which the elastic conductive sheet 152 is provided, and a through hole 151A is opened in the center of the conductive body 151.

[0055] In order to facilitate the insertion of the plug and reduce the friction of the plug, the elastic conductive sheet 152 in this embodiment is in an arc shape and is bent toward the upper end cover 132 .

[0056] In order to stabilize the conductive mechanism, Figure 2 and Figure 3 As shown, a first support platform 1315 and a second support platform 1316 are also provided on the lower shell 131, the first support platform 1315 corresponds to the first extension body 13212, the second support platform 1316 corresponds to the second extension body 13213, the first support platform 1315 and the second support platform 1316 are inverted T-shape, the first support platform 1315 and the second support platform 1316 are respectively inserted into the corresponding through holes 151A, and the two are interference fit, the first support platform 1315 and the second support platform 1316 are used to insert the columns in the through holes 151A, and the card slots are used to engage the conductive body 151 to stabilize the conductive mechanism 15.

[0057] In this embodiment, in order to allow the plug to contact and press the elastic conductive sheet, the distance between the first support platform 1315 and the second support platform 1316 and the lower housing 131 is smaller than the distance between the top of the elastic conductive sheet 152 and the lower housing 131. Therefore, when the plug of the charging plug is inserted, the arc-shaped elastic conductive sheet 152 is contacted and pressed by the plug, and rotates around the connection point with the metal sheet, causing the elastic conductive sheet 152 to gradually move toward the lower housing 131, providing a space for the plug.

[0058] In this embodiment, in order to compress the wire, Figure 2 As shown, a wire pad 1317 is also provided on the lower shell 131, and two receiving grooves matching the shape of the wire are provided on the wire pad 1317. A wire pressing rib is provided on the surface of the upper end cover 132 facing the lower shell 131, and the wire pressing rib corresponds to the wire pad 1317, so that the wire pad 1317, the wire pressing rib, the upper end cover 132 and the lower shell cooperate to press and fix the extension wire.

[0059] In this embodiment, in order to classify the L and N levels of the charging head, continue to refer to Figure 2 A wire divider 1318 is also provided on the lower shell 131, which is arranged between the wire pad 1317 and the accommodating slot 1311 for grading the wires.

[0060] The present application also provides a Figure 1 The charging device 3 shown in the figure comprises: the adapter device 1 as described above and a charging plug 2, and the charging plug 2 is arranged on the mounting boss 1321 of the adapter device 1. The specific structure of the adapter device 1 is not described in detail here.

[0061] In order to secure the charging plug on the mounting boss of the adapter device, a slot is provided on the surface of the charging plug 2 facing the mounting boss 1321 in this embodiment.

[0062] As shown in FIG. 2 , the mounting boss 1321 is disposed at one end of the upper end cover 132 . The mounting boss 1321 includes a boss body 13211 . The boss body 13211 is provided with a plug hole 13214 . The plug hole 13214 corresponds to the card slot one by one.

[0063] The following is the process of the adapter 1 locking the charging plug 2:

[0064] Insert the pin of the charging plug 2 into the pin hole provided inside the first extension body 13212 and the second extension body 13213. When the charging plug 2 is slowly pushed into the socket, the charging plug 2 applies pressure to the lock button 142 of the lock mechanism 14. The elastic member 143 of the lock mechanism 14 undergoes elastic deformation, driving the slider 141 to gradually slide toward the lower shell 131. When the slot on the surface of the charging plug 2 facing the mounting boss 1321 moves to above the lock button 142, the pressure applied to the lock button 142 disappears, the elastic member 142 resumes its elastic deformation, and the lock button 142 is snapped into the slot on the charging plug 2, completing the locking of the charging plug 2, thereby effectively preventing the charging plug from falling off.

[0065] The following is the process of the adapter 1 releasing the charging plug 2:

[0066] The stopper 144 of the locking mechanism 14 is pressed toward the lower shell 131 , and the elastic member 143 of the locking mechanism 14 is elastically deformed, driving the slider 141 to gradually slide toward the lower shell 131 , so that the locking button 142 of the locking mechanism 14 slides out of the card slot on the charging plug 2 , thereby completing the release of the charging plug 2 .

[0067] It should be understood that although this specification is described according to various embodiments, not every embodiment contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
