[0035] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10As shown, in order to solve the problems existing in the prior art, the present invention provides a portable waterproof integrated fast charging device, including a fast charging shell 31, a rotating pin assembly 19 is provided at the left end of the fast charging shell 31, a circuit extension board 17 is provided at the right end of the fast charging shell 31, a circuit board 18 is provided inside the fast charging shell 31, a first micro spur gear 21 is provided on the rotating pin assembly 19, a first fixed block 23 is fixedly installed inside the fast charging shell 31, a rotating rod 25 is rotatably installed on the first fixed block 23 through a micro plastic bearing, a second micro spur gear 24 is fixedly installed on the rotating rod 25, a gear timing belt 22 is meshed between the second micro spur gear 24 and the first micro spur gear 21, and a rotating rod 25 is fixedly installed on the rotating rod 25. A third micro spur gear 26, a movable rack 27 is meshed at the lower end of the third micro spur gear 26, a U-shaped pull rod 28 is fixedly mounted on the movable rack 27, a charging panel 37 is fixedly mounted on the side end of the U-shaped pull rod 28, two baffles 34 are provided at the right end of the fast charging shell 31, two fixed plates 35 are fixedly mounted on the opposite surfaces of the two baffles 34, a circuit connection box 11 is fixedly mounted on the circuit extension plate 17, a circuit connection plate 15 is slidably mounted in the circuit connection box 11, two second contacts 16 are provided on the circuit connection plate 15, two first contacts 13 are provided in the circuit connection box 11, and the two second contacts 16 on the circuit connection plate 15 are respectively fitted with the two first contacts 13. When the fast charging device is in use, Figure 1 As shown, the rotating pin assembly 19 and the two baffles 34 are in an open state, and the second contact 16 is located at the side end of the fast charging shell 31 and is flush with the end of the fast charging shell 31. The device only needs to insert the pin in the rotating pin assembly 19 into the power end, and then the charging port 14 at the other end thereof and the charging cable connected to the charging port 14 can be used to charge the battery inside the load device, and the charging head of the charging cable is placed in the positioning groove 36 opened by the two fixing plates 35. Under the rotation of the two torsion springs and the rotating shaft 32, the charging head can be fixed to avoid shaking of the charging head and the charging port 14. The present invention provides two fixing plates 35 and the positioning groove 36 opened by the fixing plate 35, so that the charging head can be fixed in the positioning groove 36 of the fixing plate 35, which can avoid shaking of the charging head and the charging port 14, ensure the stability of the charging connection, prevent poor contact from causing reduced charging efficiency or charging interruption, thereby improving the reliability and safety of charging, and effectively protecting the charging port 14 to avoid damage to the charging port 14 due to long-term shaking and wear.

[0036] The rotating pin assembly 19 includes a pin, a rotating shaft, and a retracting locking mechanism. The first micro spur gear 21 is fixedly mounted on the rotating shaft in the rotating pin assembly 19. The upper and lower ends of the U-shaped pull rod 28 are slidably sleeved with second fixing blocks 29. The two second fixing blocks 29 are fixedly mounted in the fast charging housing 31. When the device is not in use, Figure 2As shown, the user can store the rotating pin assembly 19, the second contact 16 and the two baffles 34 through a series of structures inside the rotating pin assembly 19, so that the fast charging housing 31 forms an integrated state. The user twists the pins inside the rotating pin assembly 19 to rotate the pins inside. At this time, the pins on the rotating pin assembly 19 drive the rotating shaft to rotate, and the rotating shaft drives the first micro spur gear 21 to rotate. The first micro spur gear 21 and the second micro spur gear 24 are meshed through the gear timing belt 22, so that when the first micro spur gear 21 rotates, it will drive the second micro spur gear 24 to rotate. At this time, the second micro spur gear 24 drives the rotating shaft. The movable rod 25 and the third micro spur gear 26 rotate, and the movable rod 25 is in a state where it can rotate and will not move left and right through the bearing and the first fixed block 23. Through the engagement between the third micro spur gear 26 and the movable rack 27, the movable rack 27 can move, and moves toward the position of the rotating pin assembly 19. At this time, the movable rack 27 drives the U-shaped pull rod 28 and the charging panel 37 to move, and the charging panel 37 will be brought into the fast charging shell 31. The two baffles 34 are installed on the fast charging shell 31 through the rotating shaft 32 and the torsion spring. Therefore, under the elastic force of the torsion spring, the two baffles 34 will be relatively opened toward the fast charging shell 31. When the charging panel 37 moves to the innermost part of the fast-charging housing 31, the two baffles 34 are also closed with the rectangular holes opened in the fast-charging housing 31. At this time, the user presses the two baffles 34 again to make the two baffles 34 and the rectangular holes opened in the fast-charging housing 31 more tightly connected. The sealing gasket provided between the baffles 34 and the rectangular holes can effectively improve the overall sealing of the fast-charging housing 31. In this way, the fast-charging device is stored. In the present invention, the baffles 34 are closed under the action of the torsion spring, and the cooperation with the rectangular holes opened in the fast-charging housing 31 and the sealing gasket improves the overall sealing of the fast-charging housing 31, effectively preventing dust, water vapor, etc. from entering the interior and protecting the interior. Circuit elements ensure the normal operation of internal elements, extend the service life of the device, and make the fast charging device portable and waterproof. The present invention uses a third micro spur gear 26, a movable rack 27, and a U-shaped pull rod 28 and other structures set inside the fast charging shell 31, so that the device can store the charging panel 37 and the like inside the fast charging shell 31. After the charging panel 37 and the charging port 14 are stored in the fast charging shell 31, dust can be effectively prevented from entering the charging port 14 when the charging port 14 is not in use, thereby maintaining the good conductivity of the charging port 14, allowing the charging device to be charged in the best state and maintain normal charging speed and efficiency.

[0037] The two baffles 34 are fixedly mounted with a rotating shaft 32, and the upper and lower ends of the two rotating shafts 32 are mounted in the fast charging shell 31 through torsion springs. A rectangular hole is provided at the side end of the fast charging shell 31, and the two baffles 34 are slidably mounted in the rectangular hole provided in the fast charging shell 31. A sealing gasket is provided between the two baffles 34 and the rectangular hole provided in the fast charging shell 31. The charging panel 37 is parallel to the rectangular hole provided in the fast charging shell 31, and a positioning groove 36 for clamping the charging connector is provided at the side end of each fixing plate 35. When the charging panel 37 on the fast charging device is received in the fast charging shell 31, the charging port 14 at the rear end of the charging panel 37 will drive the circuit connection board 15 to slide in the circuit connection box 11. The two second contacts 16 on the circuit connection board 15 will be separated from the two first contacts 13 when the fast charging head 14 moves in the slot 12. At this time, the two second contacts 16 on the circuit connection board 15 will be in a separated state. The present invention sets the connection between the circuit board 18 and the charging port 14 in the device as a contact connection, so that when the charging port 14 is not in use, the short circuit caused by unexpected circumstances can be effectively avoided. For example, when a small amount of conductive material (such as metal debris) enters the inside of the fast charging head, if a direct connection is used, these conductive materials may cause a short circuit between the charging port 14 and the circuit board 18. By using a contact connection that can be disconnected, when not in use, the charging port 14 and the circuit board 18 are in a disconnected state, which can avoid the occurrence of such a short circuit and improve the safety of the fast charging device.

[0038] A slide groove 12 is provided in the circuit connection box 11, and the circuit connection board 15 is slidably installed in the slide groove 12 provided in the circuit connection box 11. A charging port 14 is fixedly installed on the side end of the circuit connection board 15, and the charging port 14 is fixedly installed on the charging panel 37. The circuit board 18 includes a high-frequency transformer, an output rectifier filter circuit, a control chip, a fast charging protocol chip, etc., wherein the circuit board 18 is electrically connected to the rotating pin assembly 19 and the circuit extension board 17. When it is needed, it is only necessary to rotate and pull out the pin in the rotating pin assembly 19. At this time, through the reverse movement in the above structure, the movable rack 27 can drive the U-shaped pull rod 28 and the charging panel 37 to move toward the rectangle provided in the fast charging housing 31. At this time, the charging panel 37 will move the two baffles 34. The fixing plate 35 generates an extrusion force, and then the two baffles 34 are turned outward through the torsion spring between the two baffles 34 and the fast charging shell 31. When the charging panel 37 moves to be flush with the rectangular hole opened in the fast charging shell 31, it stops. At this time, the circuit connection board 15 at the rear end of the charging port 14 will also move synchronously in the slide groove 12 opened in the circuit connection box 11. When the charging panel 37 stops moving, the two second contacts 16 on the circuit connection board 15 will also be completely in contact with the two first contacts 13 inside the circuit connection box 11. In the fitted state, at this time, the circuit extension board 17 and the circuit connection box 11 and the first contact 13 are electrically connected, and the second contact 16 is electrically connected to the charging interface inside the charging port 14, so that the charging current can flow from the position of the rotating pin assembly 19 to the circuit board 18, and then be transmitted to the circuit extension board 17 and the two first contacts 13 in the circuit connection box 11 through the circuit board 18, and finally, through the contact between the first contact 13 and the second contact 16, the current is transmitted to the load device through the two second contacts 16 and the circuit connection board 15 and the charging port 14, so that the battery of the load device can be powered. The present invention uses various connecting components arranged inside the fast charging shell 31, so that when the device is needed, the pins of the rotating pin assembly 19 are rotated and pulled out, and the charging panel 37 and the baffle 34 are restored to the working state through the reverse movement, and the position changes of the charging panel 37 and the baffle 34 are linked with the rotating pin assembly 19, which effectively improves the convenience of operation, saves preparation time, and improves the use efficiency.

[0039] Working principle:

[0040] The first step is that when the fast charging device is used, Figure 1As shown, the rotating pin assembly 19 and the two baffles 34 are in an open state, and the second contact 16 is located at the side end of the fast charging shell 31 and is flush with the end of the fast charging shell 31. The device only needs to insert the pin in the rotating pin assembly 19 into the power end, and then the charging port 14 at the other end thereof and the charging cable connected to the charging port 14 can be used to charge the battery inside the load device, and the charging head of the charging cable is placed in the positioning groove 36 opened by the two fixing plates 35. Under the rotation of the two torsion springs and the rotating shaft 32, the charging head can be fixed to avoid shaking of the charging head and the charging port 14. The present invention provides two fixing plates 35 and the positioning groove 36 opened by the fixing plate 35, so that the charging head can be fixed in the positioning groove 36 of the fixing plate 35, which can avoid shaking of the charging head and the charging port 14, ensure the stability of the charging connection, prevent poor contact from causing reduced charging efficiency or charging interruption, thereby improving the reliability and safety of charging, and effectively protecting the charging port 14 to avoid damage to the charging port 14 due to long-term shaking and wear.

[0041] The second step is when the device is not in use, such as Figure 2As shown, the user can store the rotating pin assembly 19, the second contact 16 and the two baffles 34 through a series of structures inside the rotating pin assembly 19, so that the fast charging housing 31 forms an integrated state. The user twists the pins inside the rotating pin assembly 19 to rotate the pins inside. At this time, the pins on the rotating pin assembly 19 drive the rotating shaft to rotate, and the rotating shaft drives the first micro spur gear 21 to rotate. The first micro spur gear 21 and the second micro spur gear 24 are meshed through the gear timing belt 22, so that when the first micro spur gear 21 rotates, it will drive the second micro spur gear 24 to rotate. At this time, the second micro spur gear 24 drives the rotating shaft. The movable rod 25 and the third micro spur gear 26 rotate, and the movable rod 25 is in a state where it can rotate and will not move left and right through the bearing and the first fixed block 23. Through the engagement between the third micro spur gear 26 and the movable rack 27, the movable rack 27 can move, and moves toward the position of the rotating pin assembly 19. At this time, the movable rack 27 drives the U-shaped pull rod 28 and the charging panel 37 to move, and the charging panel 37 will be brought into the fast charging shell 31. The two baffles 34 are installed on the fast charging shell 31 through the rotating shaft 32 and the torsion spring. Therefore, under the elastic force of the torsion spring, the two baffles 34 will be relatively opened toward the fast charging shell 31. When the charging panel 37 moves to the innermost part of the fast-charging housing 31, the two baffles 34 are also closed with the rectangular holes opened in the fast-charging housing 31. At this time, the user presses the two baffles 34 again to make the two baffles 34 and the rectangular holes opened in the fast-charging housing 31 more tightly connected. The sealing gasket provided between the baffles 34 and the rectangular holes can effectively improve the overall sealing of the fast-charging housing 31. In this way, the fast-charging device is stored. In the present invention, the baffles 34 are closed under the action of the torsion spring, and the cooperation with the rectangular holes opened in the fast-charging housing 31 and the sealing gasket improves the overall sealing of the fast-charging housing 31, effectively preventing dust, water vapor, etc. from entering the interior and protecting the interior. Circuit elements ensure the normal operation of internal elements, extend the service life of the device, and make the fast charging device portable and waterproof. The present invention uses a third micro spur gear 26, a movable rack 27, and a U-shaped pull rod 28 and other structures set inside the fast charging shell 31, so that the device can store the charging panel 37 and the like inside the fast charging shell 31. After the charging panel 37 and the charging port 14 are stored in the fast charging shell 31, dust can be effectively prevented from entering the charging port 14 when the charging port 14 is not in use, thereby maintaining the good conductivity of the charging port 14, allowing the charging device to be charged in the best state and maintain normal charging speed and efficiency.

[0042] In the third step, when the charging panel 37 on the fast charging device is stored in the fast charging shell 31, the charging port 14 at the rear end of the charging panel 37 will drive the circuit connection board 15 to move in the slide groove 12 opened in the circuit connection box 11. At this time, the two second contacts 16 on the circuit connection board 15 will be in a separated state from the two first contacts 13. The present invention sets the connection between the circuit board 18 and the charging port 14 in the device as a contact connection, so that when the charging port 14 is not in use, short circuits caused by unexpected situations can be effectively avoided. For example, when a small amount of conductive material (such as metal debris) enters the fast charging head, if a direct connection is used, these conductive materials may cause a short circuit between the charging port 14 and the circuit board 18. By using a contact connection that can break contact, when not in use, the charging port 14 and the circuit board 18 are in a broken contact state, which can avoid the occurrence of such a short circuit and improve the safety of the fast charging device.

[0043] The fourth step, when it is needed, just rotate and pull out the pin in the rotating pin assembly 19, and through the reverse movement in the above structure, the movable rack 27 can drive the U-shaped pull rod 28 and the charging panel 37 to move toward the rectangle opened in the fast charging shell 31, and the charging panel 37 will generate an extrusion force on the fixed plate 35 on the two baffles 34, and then the two baffles 34 can be turned outward through the torsion spring between the two baffles 34 and the fast charging shell 31, and when the charging panel 37 moves to the rectangular hole opened in the fast charging shell 31, it stops. At this time, the circuit connection board 15 at the rear end of the charging port 14 will also synchronously move in the slide groove 12 opened in the circuit connection box 11, and when the charging panel 37 stops moving, the two second contacts 16 on the circuit connection board 15 will also be completely in a fit state with the two first contacts 13 inside the circuit connection box 11, and at this time, through the circuit extension board 17 and the circuit connection box 11 and the first contacts 13 The first contact 13 and the second contact 16 are electrically connected to each other, and the second contact 16 is electrically connected to the charging interface inside the charging port 14, so that the charging current can flow from the position of the rotating pin assembly 19 to the circuit board 18, and then be transmitted to the circuit extension board 17 and the two first contacts 13 in the circuit connection box 11 through the circuit board 18. Finally, through the contact between the first contact 13 and the second contact 16, the current is transmitted to the load device through the two second contacts 16, the circuit connection board 15 and the charging port 14, so that the battery of the load device can be powered. The present invention uses various connecting components arranged inside the fast charging shell 31, so that when the device is needed, the pin of the rotating pin assembly 19 is rotated and pulled out, and the charging panel 37 and the baffle 34 are restored to the working state through the reverse movement, and the position change of the charging panel 37 and the baffle 34 is linked with the rotating pin assembly 19, which effectively improves the convenience of operation, saves preparation time, and improves the use efficiency.

[0044] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
