[0035] The following is for reference. Figures 1 to 7 The charger described in this application is described in detail.

[0036] refer to Figure 1 According to an embodiment of the present invention, the charger includes a housing 100, a pin structure 200, and a plug structure 300. The housing 100 has a receiving groove 111. The pin structure 200 is movably disposed on the housing 100 and can be received in or extend out of the receiving groove 111 under the action of external force. The plug structure 300 is detachably connected to the housing 100 and electrically connected to the pin structure 200. The plug structure 300 is disposed at the opening of the receiving groove 111 and closes the receiving groove 111.

[0037] It should be noted that when the charger of this application is being carried normally, the plug structure 200 is stored in the receiving slot 111. When the charger needs to be used, when facing the first type of socket corresponding to the plug structure 200, the user can detach the plug structure 300 from the housing 100 and extend the plug structure 200 from the receiving slot 111. At this time, the plug structure 200 can be smoothly inserted into the first type of socket, so that the charger of this application can still be used normally when facing the first type of socket. When facing the second type of socket corresponding to the plug structure 300, the user can drive the plug structure 200 to retract into the receiving slot 111 and detachably connect the plug structure 300 to the housing 100. At this time, the plug structure 300 can be smoothly inserted into the second type of socket, so that the charger of this application can still be used normally when facing the second type of socket. Therefore, the charger of this application can be adapted to multiple types of sockets, improving the versatility of the charger of this application.

[0038] It is understood that since the plug structure 300 is located at the opening of the receiving groove 111 and closes the receiving groove 111, after the plug structure 300 is installed on the housing 100, the plug structure 300 can cover the receiving groove 111 on the housing 100, so as to hide the receiving groove 111 and the pin structure 200 inside the receiving groove 111, thereby improving the aesthetics of the charger of this application.

[0039] It is understandable that since the plug structure 300 can be electrically connected to the pin structure 200 after it is installed on the housing 100, there is no need to set an additional electrical connection structure on the housing 100 to electrically connect with the plug structure 300, thereby simplifying the overall structure of the charger of this application.

[0040] It is worth noting that in some embodiments of this utility model, the charger includes plug structures 300 of various specifications, and users can install the corresponding plug structure 300 onto the housing 100 according to their actual needs.

[0041] In some embodiments of this utility model, reference is made to Figures 1 to 4 The plug structure 300 has a plug portion 310, which is plugged into and connected to the groove wall of the receiving groove 111. The plug portion 310 is provided with a relief groove 311 for avoiding the pin structure 200. An electrical connector 320 is provided in the relief groove 311 for electrical connection with the pin structure 200.

[0042] Furthermore, when achieving a detachable connection between the plug structure 300 and the housing 100, the user can insert the plug portion 310 into the receiving groove 111 to achieve a detachable connection between the plug structure 300 and the housing 100. Simultaneously, since the plug portion 310 is provided with a clearance groove 311, and an electrical connector 320 is provided within the clearance groove 311, after the plug portion 310 is inserted into the receiving groove 111, the pin structure 200 within the receiving groove 111 can extend into the clearance groove 311, thereby achieving clearance between the plug portion 310 and the pin structure 200. By providing an electrical connector 320 in the clearance groove 311, after the plug part 310 is inserted into the receiving groove 111, the pin structure 200 can automatically insert into the clearance groove 311 and contact with the electrical connector 320 in the clearance groove 311, and connect electrically, thereby realizing the electrical connection between the plug structure 300 and the pin structure 200; when separating the plug structure 300 from the housing 100, the user can directly pull the plug part 310 out of the receiving groove 111 to separate the plug structure 300 from the housing 100.

[0043] It is understandable that by providing a plug-in connection between the plug portion 310 and the groove wall of the receiving groove 111, the assembly and disassembly of the plug structure 300 and the housing 100 can be made more convenient and quick. By providing an electrical connector 320 in the clearance groove 311, when the plug portion 310 is inserted into the receiving groove 111, the pin structure 200 can extend into the clearance groove 311 to make an electrical connection with the electrical connector 320, thereby realizing the electrical connection between the plug structure 300 and the pin structure 200.

[0044] In a further embodiment of the present invention, a plug protrusion 330 is formed on the plug structure 300, and a plug groove 112 is provided on the housing 100 corresponding to the plug protrusion 330, and the plug protrusion 330 is plugged into and disconnected from the groove wall of the plug groove 112.

[0045] For example, such as Figures 1 to 4 As shown, the rear end face of the plug structure 300 is provided with a plug portion 310 and a plug protrusion 330. The plug protrusion 330 is located below the plug portion 310. The front end face of the housing 100 is provided with a receiving groove 111 and a plug groove 112. The plug groove 112 is located below the receiving groove 111.

[0046] Furthermore, when it is necessary to connect the plug structure 300 and the housing 100, the plug portion 310 can be engaged in the receiving groove 111, and the plug protrusion 330 can be engaged in the plug groove 112, thereby connecting the plug structure 300 and the housing 100; when it is necessary to disassemble the plug structure 300 and the housing 100, the user can pull the plug portion 310 out of the receiving groove 111 and pull the plug protrusion 330 out of the plug groove 112, thereby disassembling the plug structure 300 and the housing 100.

[0047] Understandably, the design of the insertion protrusion 330 on the plug structure 300 and the insertion groove 112 on the housing 100 makes the connection between the plug structure 300 and the housing 100 more secure.

[0048] To improve the connection strength between the insertion protrusion 330 and the insertion groove 112, in a further embodiment of this utility model, referring to... Figures 2 to 4 The side end of the insertion protrusion 330 is provided with a hook 331, and the side wall of the insertion groove 112 is provided with a hook groove 112a, and the hook 331 passes through the hook groove 112a.

[0049] It is understandable that after the insertion protrusion 330 is inserted into the insertion groove 112, the hook 331 can be inserted into the hook groove 112a. At this time, the hook 331 can abut against the groove wall of the hook groove 112a to prevent the insertion protrusion 330 from disengaging from the insertion groove 112, thereby improving the connection strength between the insertion protrusion 330 and the insertion groove 112.

[0050] It should be noted that when it is necessary to disengage the plug protrusion 330 from the plug slot 112, the user needs to shake the plug structure 300 within the plug slot 112 so that the hook 331 can disengage from the hook slot 112a. At this time, the plug protrusion 330 can smoothly disengage from the plug slot 112.

[0051] In some embodiments of this utility model, reference is made to Figure 1 The charger also includes a locking structure 400, which is located inside the housing 100 and is used to lock and fix the plug structure 300 onto the housing 100.

[0052] It is understandable that by setting the locking structure 400, after the plug structure 300 is installed on the housing 100, the locking structure 400 can lock and fix the plug structure 300 so that the plug structure 300 can be firmly installed on the housing 100.

[0053] In a further embodiment of the present invention, the locking structure 400 includes a locking member 410 and an elastic connector 420. The locking member 410 is slidably disposed on the housing 100 and has a snap-fit ​​protrusion 412a. The plug structure 300 is provided with a snap-fit ​​groove 312. The elastic connector 420 is connected to the locking member 410 and the housing 100 respectively. The elastic connector 420 is used to provide elastic force to keep the snap-fit ​​protrusion 412a inserted into the snap-fit ​​groove 312.

[0054] For example, such as Figure 3 and Figure 4 As shown, the snap-fit ​​groove 312 is provided on the plug part 310. After the plug structure 300 is installed on the housing 100, the plug part 310 passes through the receiving groove 111. Under the elastic force of the elastic connector 420, the snap-fit ​​protrusion 412a on the locking member 410 passes through the snap-fit ​​groove 312 to prevent the plug part 310 from disengaging from the receiving groove 111, thereby achieving a stable connection between the plug structure 300 and the housing 100.

[0055] Understandably, when a user needs to disassemble the plug structure 300, the user can overcome the elastic force of the elastic connector 420 so that the locking member 410 disengages from the snap-fit ​​groove 312. At this time, the user can drive the plug part 310 to smoothly disengage from the receiving groove 111, so as to realize the disassembly of the plug structure 300 on the housing 100.

[0056] In some embodiments of this utility model, the locking member 410 includes a connecting part 411, a snap-fit ​​part 412, and a pressing part 413. The snap-fit ​​part 412 and the pressing part 413 are respectively connected to the two ends opposite to the connecting part 411. The snap-fit ​​protrusion 412a is provided at the end of the snap-fit ​​part 412 near the pressing part 413. The end face of the pressing part 413 away from the snap-fit ​​part 412 forms a pressing surface 413a.

[0057] For example, such as Figures 5 to 7 As shown, the locking member 410 includes a connecting part 411, a snap-fit ​​part 412, and a pressing part 413. The snap-fit ​​part 412 is connected to the lower end of the connecting part 411, and the pressing part 413 is connected to the upper end of the connecting part 411. A snap-fit ​​protrusion 412a is provided at the upper end of the snap-fit ​​part 412, and the upper end surface of the pressing part 413 forms a pressing surface 413a.

[0058] Furthermore, after the plug portion 310 passes through the receiving groove 111, under the elastic force of the elastic connector 420, the locking member 410 can move upward, so that the snap-fit ​​protrusion 412a passes upward into the snap-fit ​​groove 312 of the plug portion 310, thereby locking and fixing the plug structure 300. When the user needs to remove the plug structure 300 from the housing 100, the user can press down on the pressing surface 413a of the locking member 410 to drive the entire locking member 410 to move downward against the elastic force of the elastic connector 420, and cause the snap-fit ​​protrusion 412a to disengage from the snap-fit ​​groove 312 of the plug portion 310. At this time, the user can smoothly drive the plug portion 310 to disengage from the receiving groove 111, thereby removing the plug structure 300 from the housing 100.

[0059] Understandably, since the snap-fit ​​protrusion 412a is located at the end of the snap-fit ​​portion 412 near the pressing portion 413, and the pressing portion 413 forms a pressing surface 413a away from the end face of the snap-fit ​​portion 412, when the user needs to release the locking structure 400 from the plug structure 300, the user can release the locking structure 400 from the plug structure 300 by pressing the pressing surface 413a. The operation of the locking structure 400 is simpler and more convenient for the user.

[0060] In some embodiments of this utility model, the snap-fit ​​part 412 is provided with a limiting groove 412b at one end away from the snap-fit ​​protrusion 412a; the elastic connector 420 is a spring, one end of the spring extends into the limiting groove 412b and abuts against the bottom of the limiting groove 412b, and the other end of the spring abuts against the housing 100.

[0061] For example, such as Figure 6 and Figure 7 As shown, the lower end of the snap-fit ​​part 412 is provided with a limiting groove 412b, the elastic connector 420 is a spring, the upper end of the spring extends into the limiting groove 412b and abuts against the bottom of the limiting groove 412b, and the lower end of the spring abuts against the housing 100.

[0062] Understandably, springs have a simple structure and are inexpensive.

[0063] It is understandable that by setting the limiting groove 412b, on the one hand, it facilitates the connection between the spring and the locking member 410, and on the other hand, the groove wall of the limiting groove 412b can limit the spring to ensure that the spring can stably deform in the vertical direction.

[0064] In some embodiments of this utility model, the housing 100 includes an outer shell 110 and a mounting bracket 120. The outer shell 110 is provided with a receiving cavity 113, the mounting bracket 120 is disposed in the receiving cavity 113, the outer shell 110 is formed with a receiving groove 111, the locking member 410 is disposed in the receiving cavity 113, the snap-fit ​​part 412 is slidably connected to the mounting bracket 120, and the pressing part 413 extends to the outside of the receiving cavity 113.

[0065] For example, such as Figure 5 As shown, the housing 100 includes an outer shell 110 and a mounting bracket 120. A receiving cavity 113 is formed inside the outer shell 110. The mounting bracket 120 is disposed inside the receiving cavity 113 and has a vertically extending slide groove 121. A locking member 410 is disposed inside the receiving cavity 113. A snap-fit ​​part 412 is slidably disposed in the slide groove 121 in the vertical direction. An opening is provided at the upper end of the receiving cavity 113. A pressing part 413 passes through the opening and extends upward to the outside of the receiving cavity 113.

[0066] Furthermore, when the user presses the pressing part 413, the pressing part 413 can drive the entire locking member 410 to move downward along the slide groove 121, so that the snap-fit ​​protrusion 412a on the locking member 410 disengages from the snap-fit ​​groove 312.

[0067] Understandably, the design of the slide groove 121 allows the locking element 410 to move accurately in the vertical direction under the limitation of the slide groove 121 wall.

[0068] In some embodiments of this utility model, reference is made to Figure 5 The pin structure 200 includes a rotating shaft 210, a first pin 220 and a second pin 230. The rotating shaft 210 is rotatably connected to the housing 100, and both the first pin 220 and the second pin 230 are connected to the rotating shaft 210.

[0069] Understandably, the hinge 210 allows the user to rotate the pin structure 200 around the hinge 210 so that the pin structure 200 can be received into the receiving groove 111 or extend out of the receiving groove 111, making it more convenient for the user to operate the pin structure 200.

[0070] For details, please refer to Figure 5 The rotating shaft 210 is rotatably mounted on the mounting bracket 120.

[0071] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
