[0028] like Figures 1 to 5 As shown, an automatic plug-in charger comprises a charger body 1, the charger body 1 comprises a plug, a groove is provided on a side of the charger body 1 close to the socket, a pop-up mechanism 2 for pushing the charger body 1 to move is installed inside the groove of the charger body 1, a protective mechanism 3 is installed on the outer surface of the charger body 1, two groups of grooves are provided on the side of the pop-up mechanism 2 away from the charger body 1, and positioning mechanisms 4 for limiting the moving range of the pop-up mechanism 2 are installed inside the two groups of grooves; specifically, the pop-up mechanism 2 is closed when the charger body 1 is disconnected, so that the internal device of the pop-up mechanism 2 pushes the charger body 1 to move to the side of the pop-up mechanism 2 away from the connection socket, thereby completing the automatic unplugging of the charger body 1 when the power is off, thereby improving the safety of the charger body 1 during use.

[0029] At the same time, the protective mechanism 3 is positioned on the outer surface of the charger body 1 so that the protective mechanism 3 wraps and protects the outer surface of the charger body 1, thereby minimizing wear of the charger body 1 during daily use, thereby increasing the service life of the charger body 1; the inner walls on the opposite sides of the two sets of positioning mechanisms 4 are clamped on the outer surface of the connecting socket, so that the two sets of positioning mechanisms 4 limit the moving position of the pop-up mechanism 2 on the front side of the connecting socket, thereby minimizing the movement of the pop-up mechanism 2 during use.

[0030] like Figure 1 and Figure 2 As shown, the pop-up mechanism 2 includes a U-shaped electromagnetic block 202, a spring telescopic rod 203 and a special-shaped fixing plate 201. A groove is provided on the side of the charger body 1 close to its own plug-in sheet, and the spring telescopic rod 203 is plugged into the inside of the groove of the charger body 1. A through hole is provided on the top of the inner wall of the groove of the charger body 1, and a groove is provided on the outer surface of the spring telescopic rod 203. A rubber block 204 is bonded inside the groove of the spring telescopic rod 203, and the position of the rubber block 204 is located at the lower end of the through hole in the charger body 1. The U-shaped electromagnetic block 202 is installed on the side of the charger body 1 close to the spring telescopic rod 203, and the outer surface of the plug-in sheet of the charger body 1 is plugged with a special-shaped fixing plate 201. The end of the spring telescopic rod 203 away from the charger body 1 is installed on the side of the special-shaped fixing plate 201 close to the charger body 1, and the U-shaped electromagnetic block 202 and the output end of the charger body 1 are electrically connected;

[0031] Specifically, when the charger body 1 is disconnected from a connecting device such as a mobile phone, an electrical connection is made between the U-shaped electromagnetic block 202 and the output end of the charger body 1, so that the U-shaped electromagnetic block 202 is closed after the charger body 1 is disconnected from a connecting device such as a mobile phone, and then the spring telescopic rod 203 pushes the charger body 1 to move to the side of the special-shaped fixing plate 201 away from the connecting socket under the action of elastic potential energy, thereby completing the automatic pull-out of the charger body 1 when the power is off, thereby improving the safety of the charger body 1 during use; the rubber block 204 is made of rubber, so that the spring telescopic rod 203 is snapped into the groove of the charger body 1 after the rubber block 204 is restored, and then the rubber block 204 is snapped into the through hole of the charger body 1 to limit the moving position of the spring telescopic rod 203 in the groove of the charger body 1, thereby trying to avoid the spring telescopic rod 203 from being disconnected from the charger body 1 during use, thereby improving the stability of the pop-up mechanism 2 during use.

[0032] like Figure 1 and Figure 2As shown, a plug rod 5 is inserted into the through hole of the charger body 1, and the outer surface of the special-shaped fixing plate 201 is coated with insulating paint; specifically, by pushing the plug rod 5, the plug rod 5 is inserted into the through hole of the charger body 1, and the rubber block 204 inside the through hole of the charger body 1 is pushed to move downward, and the rubber block 204 is pushed into the groove of the spring telescopic rod 203, and then the special-shaped fixing plate 201 is pulled to drive the spring telescopic rod 203 to move out of the groove of the charger body 1, so that the staff can quickly disassemble the charger body 1 and the ejection mechanism 2, and then the subsequent charger body 1 or the ejection mechanism 2 can be disassembled and replaced when damaged, thereby reducing the subsequent maintenance cost of the device; the insulating paint has good insulation, so that the staff is not easily electrocuted by the special-shaped fixing plate 201 when touching the special-shaped fixing plate 201, thereby improving the safety of the device during use.

[0033] like Figure 1 and Figure 2 As shown, the protective mechanism 3 includes a U-shaped fixing plate 301 and a protective cover 302. The U-shaped fixing plate 301 is installed on the outer surface of the charger body 1, and the protective cover 302 is slidably connected to the outer surface of the charger body 1. The side of the protective cover 302 close to the special-shaped fixing plate 201 is bonded to the side of the U-shaped fixing plate 301 away from the special-shaped fixing plate 201; specifically, when the pop-up mechanism 2 and the charger body 1 are assembled, the protective cover 302 is pushed to bond the side of the protective cover 302 close to the special-shaped fixing plate 201 to the side of the U-shaped fixing plate 301 away from the special-shaped fixing plate 201, so that the protective cover 302 wraps the outer surface of the charger body 1, and then the protective cover 302 blocks the exposed through holes of the charger body 1, thereby improving the aesthetics of the charger body 1 during use.

[0034] At the same time, by setting the protection mechanism 3 on the outer surface of the charger body 1, the protection mechanism 3 wraps and protects the outer surface of the charger body 1, thereby minimizing the wear of the charger body 1 during daily use, thereby increasing the service life of the charger body 1.

[0035] like Figure 3 As shown, a groove is provided at the bottom of the inner wall of the protective cover 302, and the inner contour of the groove of the protective cover 302 is matched with the outer contour of the plug rod 5; specifically, when the plug rod 5 is removed from the through hole of the charger body 1 and is idle, the plug rod 5 is pushed and connected to the inside of the U-shaped fixing plate 301, so that the internal groove of the U-shaped fixing plate 301 stores the plug rod 5, thereby minimizing the loss of the plug rod 5 during idleness, thereby increasing the service life of the plug rod 5.

[0036] like Figure 1 and Figure 2As shown, the two groups of positioning mechanisms 4 both include an L-shaped slider 401, and two groups of card slots are provided on the side of the special-shaped fixing plate 201 away from the charger body 1, and the two groups of L-shaped sliders 401 are respectively slidably connected inside the two groups of card slots of the special-shaped fixing plate 201, and the two groups of L-shaped sliders 401 are installed on the opposite sides of the two groups of L-shaped sliders 401. The insides of the two groups of fixing blocks 402 are provided with threaded holes, and the internal threads of the two groups of fixing blocks 402 are connected to screws 403, and the upper and lower sides of the special-shaped fixing plate 201 are provided with threaded holes, and the positions of the two groups of threaded holes of the special-shaped fixing plate 201 are respectively located on the moving paths of the two groups of screws 403;

[0037] Specifically, when the side of the special-shaped fixing plate 201 away from the charger body 1 abuts against the surface of the connecting socket, the two groups of L-shaped sliders 401 are used to make the inner walls on the opposite sides of the two groups of L-shaped sliders 401 abut against the upper and lower sides of the connecting socket respectively, and then by rotating the two groups of screws 403, the adjacent ends of the two groups of screws 403 are respectively installed in the two groups of threaded holes of the special-shaped fixing plate 201, so that the inner walls on the opposite sides of the two groups of L-shaped sliders 401 are clamped on the outer surface of the connecting socket, and then the two groups of positioning mechanisms 4 limit the moving position of the special-shaped fixing plate 201 on the front side of the connecting socket, so as to avoid the movement of the pop-up mechanism 2 during use as much as possible, thereby improving the stability of the pop-up mechanism 2 during use.

[0038] like Figure 1 As shown, the inner walls of the two groups of L-shaped sliders 401 on the opposite sides are both bonded with anti-skid pads 6; specifically, when the inner walls of the two groups of L-shaped sliders 401 are respectively in contact with the upper and lower sides of the connecting socket of the charger body 1, the positions of the two groups of anti-skid pads 6 are set between the inner walls of the two groups of L-shaped sliders 401 and the upper and lower contact surfaces of the connecting socket, so that the two groups of anti-skid pads 6 increase the friction between the two groups of L-shaped sliders 401 and the contact surfaces of the connecting socket, thereby making it difficult for the two groups of positioning mechanisms 4 to move when the charger body 1 is hit, thereby improving the stability of the two groups of positioning mechanisms 4 during use.

[0039] In summary: by electrically connecting the U-shaped electromagnetic block 202 and the output end of the charger body 1, the U-shaped electromagnetic block 202 is turned off after the charger body 1 and the connecting device such as the mobile phone are disconnected, so that the spring telescopic rod 203 pushes the charger body 1 to move to the side of the special-shaped fixing plate 201 away from the connecting socket under the action of elastic potential energy, thereby completing the automatic removal of the charger body 1 when the power is cut off; by pushing the plug rod 5, the plug rod 5 is inserted into the through hole of the charger body 1 to push the rubber block 204 inside the through hole of the charger body 1 to move downward, and the rubber block 204 is pushed into the groove of the spring telescopic rod 203, and then the special-shaped fixing plate 201 is pulled to drive the spring telescopic rod 203 to move out of the groove of the charger body 1, so that the staff can quickly disassemble the charger body 1 and the pop-up mechanism 2, so that the subsequent charger body 1 or the pop-up mechanism 2 can be disassembled and replaced when damaged.

[0040] At the same time, by pushing the protective cover 302, the side of the protective cover 302 close to the special-shaped fixing plate 201 is bonded to the side of the U-shaped fixing plate 301 away from the special-shaped fixing plate 201, so that the protective cover 302 wraps the outer surface of the charger body 1, and then the protective cover 302 covers the through hole exposed to the outside of the charger body 1; by pushing the plug rod 5, the plug rod 5 is snapped into the inside of the U-shaped fixing plate 301, so that the internal groove of the U-shaped fixing plate 301 stores the plug rod 5, thereby trying to avoid the plug rod 5 from being lost during idleness. ; Through the two groups of L-shaped sliders 401, the inner walls of the opposite sides of the two groups of L-shaped sliders 401 are respectively abutted against the upper and lower sides of the connecting socket, and then by rotating the two groups of screws 403, the adjacent ends of the two groups of screws 403 are respectively installed in the two groups of threaded holes of the special-shaped fixing plate 201, so that the inner walls of the opposite sides of the two groups of L-shaped sliders 401 are clamped on the outer surface of the connecting socket, and then the two groups of positioning mechanisms 4 limit the moving position of the special-shaped fixing plate 201 on the front side of the connecting socket, thereby minimizing the movement of the pop-up mechanism 2 during use.
