[0028] The bracket 12 of the charger body 1 is pivotally arranged on the assembling portion 102, and one end of the bracket 12 is located in the housing 10, and the other end protrudes out of the mounting hole 1021 and the assembling portion 102. The bracket 12 can be pivoted relative to the assembling portion 102 to be parallel to the first side surface 101 or perpendicular to the first side surface 101. One end of the bracket 12 located in the housing 10 has a pair of first contact foot portions 121, and the other end protruding out of the assembling portion 102 has a pair of second contact foot portions 122. The bracket 12 is the main structure for pivoting the plug assembly 2. More specifically, the bracket 12 can be assembled from the inside of the housing 10, that is, through the mounting hole 1021 and pivotally arranged on the assembling portion 102, so that the bracket 12 is assembled in a state that one end protrudes out of the assembling portion 102 and the other end is located in the housing 10. In an embodiment, the pair of first contact foot portions 121 and the pair of second contact foot portions 122 of the bracket 12 are two ends of a conductive column 6, which protrude out of the two ends of the support rod 123 after being arranged in the support rod 123. By making the pair of first contact foot portions 121 and the pair of second contact foot portions 122 two ends of the same component, the conductivity of the pair of first contact foot portions 121 and the pair of second contact foot portions 122 can be improved. Since the bracket 12 is made of a non-conductive material in principle, and the pair of first contact foot portions 121 and the pair of second contact foot portions 122 need to have conductive properties, the above structure can effectively improve the process convenience, and the bracket 12 has good insulation performance, and the pair of first contact foot portions 121 and the pair of second contact foot portions 122 have excellent electrical conductivity.

[0029] The pair of circuit board conductive spring sheets 13 are arranged on the circuit board assembly 11 to contact the pair of first contact foot portions 121 of the bracket 12 when the bracket 12 is pivoted to be perpendicular to the first side surface 101 to form a conductive connection. Specifically, the circuit board assembly 11 can have through holes to facilitate the arrangement of the pair of circuit board conductive spring sheets 13. The pair of circuit board conductive spring sheets 13 are main components for conducting electricity from the plug assembly 2 to the circuit board assembly 11. According to the assembly and application requirements, the pair of circuit board conductive spring sheets 13 can further have a hook structure A to be stably assembled on the circuit board assembly 11, and a contact section B with elastic force relative to the pair of first contact foot portions 121 to provide a reverse force when the pair of first contact foot portions 121 contacts the contact section B to enhance the contact reliability of the pair of first contact foot portions 121. The contact section B can be elastically swung at the through hole of the circuit board assembly 11.

[0030] The plug assembly 2 is assembled on the assembling portion 102, and the plug assembly 2 is parallel to the first side surface 101 or perpendicular to the first side surface 101 due to the pivoting of the bracket 12. The plug assembly 2 includes an inner cover 20, a pair of conductive adapter springs 21, a pair of conductive fixing members 22, and a plug structure 23.

[0031] The inner cover 20 is assembled on the assembling portion 102 and has a first gap 201. The pair of conductive adapter springs 21 is symmetrically assembled on one side of the inner cover 20 and respectively has a clamping portion 211. The pair of conductive fixing members 22 is arranged corresponding to the pair of conductive adapter springs 21. One end of the pair of conductive fixing members 22 is inserted into the pair of conductive adapter springs 21 and the inner cover 20 to be combined and fixed with the pair of second pin portions 122, and the other end is in contact with the pair of conductive adapter springs 21. The pair of conductive fixing members 22 can enhance the contact stability of the pair of second pin portions 122 of the bracket 12 and the pair of conductive adapter springs 21, so that the overall conductive path remains in good contact state. The inner cover 20 can prevent the pair of conductive adapter springs 21 from being exposed when the plug assembly 2 is pivoted to be parallel to the first side surface 101, to avoid the risk of electric shock caused by accidental contact by children, effectively improving product safety. The plug structure 23 includes an outer cover 231 and a plug pin 232. The outer cover 231 is assembled on the inner cover 20 and has a second gap 2311 corresponding to the first gap 201. The plug pin 232 is inserted from the inner cover 231 to the outside of the outer cover 231, and one end of the plug pin 232 located in the outer cover 231 has a pair of third pin portions 2321. The pair of third pin portions 2321 passes through the clamping portion 211 and is clamped and fixed by the clamping portion 211. The pair of third pin portions 2321 can be inserted and combined to form a tight clamping effect, so that the pair of third pin portions 2321 is not easy to exit or pop out of the clamping portion 211, which can ensure good contact state between the plug pin 232 and the conductive adapter springs 21. The plug assembly 2 is an element for connecting with a socket. Electricity obtained from the socket is conducted to the circuit board assembly 11 through the third pin portions 2321 of the plug pin 232, the pair of conductive adapter springs 21, the pair of second pin portions 122, the pair of first pin portions 121, and the pair of circuit board conductive springs 13. The charging interface 111 of the circuit board assembly 11 provides electricity to electronic devices to achieve the purpose of charging. The part of the plug pin 232 inserted outside the outer cover 231 can be a pin of Type C or Type F according to European standards, Type A or Type B according to American standards, Type G according to British standards, and other types, to meet the voltage, frequency, and safety requirements of different places.

[0032] In summary, the folding charger 9 can achieve the effect of not reserving space for accommodating the plug assembly 2 in the charger body 1, thereby effectively maintaining the overall volume of the folding charger 9 to be light, thin, small and short. Through the bracket 12 and the assembly portion 102, the plug assembly 2 can be pivoted to a state perpendicular to the first side 101 for use, or pivoted to a state parallel to the first side 101 for folding and storage, thereby having the advantage of being convenient to carry and use. In addition, through the bracket 12, the pair of circuit board conductive springs 13, the pair of conductive adapter springs 21, and the pair of conductive fixing members 22, a conductive path with very stable contact state can be formed, thereby effectively avoiding the contact failure phenomenon caused by the dislocation of the elements due to the pivoting operation of the bracket 12 and the plug assembly 2, and greatly improving the use reliability of the charger.

[0033] In a preferred embodiment, the folding charger 9 further comprises a pivot spring 3 and a cover plate 4. The support 12 has a pair of support rods 123 and a shaft rod 124. The pair of support rods 123 are symmetrically arranged. The shaft rod 124 is arranged between the pair of support rods 123 and is perpendicular to the pair of support rods 123. The shaft rod 124 has a first guide concave surface 1241 and a second guide concave surface 1242. The first guide concave surface 1241 is arranged adjacent to the second guide concave surface 1242. The pair of first pin portions 121 and the pair of second pin portions 122 are respectively located at opposite ends of the pair of support rods 123. The cover plate 4 is arranged in the housing 10 and is located at one side of the shaft rod 124. The pivot spring 3 is arranged between the shaft rod 124 and the cover plate 4. The pivot spring 3 has a convex arc section 31. When the support 12 is pivoted to be parallel to the first side surface 101, the convex arc section 31 abuts against the first guide concave surface 1241. When the support 12 is pivoted to be perpendicular to the first side surface 101, the convex arc section 31 abuts against the second guide concave surface 1242. Through the first guide concave surface 1241 and the second guide concave surface 1242 of the shaft rod 124, in combination with the convex arc section 31 of the pivot spring 3, the plug assembly 2 can be automatically slid to be positioned when pivoted to be perpendicular to the first side surface 101 or parallel to the first side surface 101. Thus, the user can easily know whether the plug assembly 2 is rotated to the appropriate position for use or storage. Specifically, when the user pivots the plug assembly 2 to be perpendicular to the first side surface 101, the shaft rod 124 is rotated with the center as the center. When the plug assembly 2 is about to be perpendicular to the first side surface 101, the second guide concave surface 1242 can quickly make the convex arc section 31 slide into the second guide concave surface 1242 to be in contact and abut against each other to be positioned. The same is true when the plug assembly 2 is pivoted to be parallel to the first side surface 101. When the plug assembly 2 is about to be parallel to the first side surface 101, the first guide concave surface 1242 can quickly make the convex arc section 31 slide into the first guide concave surface 1242 to be in contact and abut against each other to be positioned. The cover plate 4 can provide a pressing and fixing effect on the pivot spring 3 to avoid the pivot spring 3 from being forced to swing and causing the plug assembly 2 to be loose or deviated.

[0034] Further, the cover plate 4 is screwed into the housing 10. Thus, the assembly firmness of the cover plate 4 and the housing 10 can be enhanced, the bearing capacity of the pivot spring 3 swinging force can be improved, and the stability of the overall structure can be maintained.

[0035] In addition, regarding the clamping portions 211 of the pair of conductive adapter springs 21, in an embodiment, each clamping portion 211 has a pair of clamping pieces 2111 arranged in mirror image, and the distance between the pair of clamping pieces 2111 is tapered toward the inner cover 20. More specifically, the clamping portions 211 can form a stable assembly strength relative to the pair of third pin portions 2321, and each clamping portion 211 has the pair of clamping pieces 2111 described above, so that the pair of clamping portions 211 can further have the tapered opening of the pair of clamping pieces 2111, so that when the pair of third pin portions 2321 passes through the pair of clamping portions 211, the pair of clamping pieces 2111 of each clamping portion 211 can form a barb-like fixing effect, and the pair of conductive adapter springs 21 is less likely to pop out or detach, so that the elements on the conductive path can maintain good contact.

[0036] To allow the plug assembly 2 to be pivoted to the use state perpendicular to the first side surface 101, and to be stably maintained in the structure, to avoid the plug assembly 2 from being automatically bent close to the first side surface 10 due to accidental impact, the assembly portion 102 can have at least one protruding rib 1022, the inner cover 20 can have at least one positioning hole 202, and when the plug assembly 2 is pivoted to the state perpendicular to the first side surface 101, the protruding rib 1022 is clamped and fixed with the positioning hole 202. In this way, the plug assembly 2 can be more firmly fixed in the state perpendicular to the first side surface 101, and the overall structural stability is improved.

[0037] In addition, considering the assembly stability of the pair of conductive adapter springs 21 and the pair of second pin portions 122, the pair of conductive fixing members 22 can be screw structures, which are combined and fixed with the pair of second pin portions 122 in a locking manner, so that the pair of conductive adapter springs 21 and the pair of second pin portions 122 can be in good contact, and have excellent electrical conduction stability.

[0038] In another aspect, to make the inner cover 20 and the outer cover 231 have better assembly stability, avoid structural disengagement when rotating the plug assembly 2, preferably the inner side of the outer cover 231 has at least one first combination part 2312, the outer side of the inner cover 20 has at least one second combination part 203, the outer cover 231 and the inner cover 20 are assembled and fixed through the first combination part 2312 and the second combination part 203, wherein the first combination part 2312 and the second combination part 203 are corresponding groove and block structures. In this way, the outer cover 231 and the inner cover 20 can have firm structural assembly strength and stability, and in the present embodiment, the number of the first combination part 2312 and the second combination part 203 is two, the first combination part 2312 and the second combination part 203 are symmetrically arranged, and the first combination part 2312 is a block structure and the second combination part 203 is a corresponding groove structure. However, this is only a preferred structure example, and the present application is not limited thereto.

[0039] Please continue to see Figure 6 As shown in FIG. 9, which is a folded charger assembly perspective view of another embodiment of the present application. In this embodiment, the folded charger 9 further comprises a retractable charging cord 5, and the shell 10 has a receiving groove 103 on the outer side, the retractable charging cord 5 is arranged in the shell 10 and one end is located in the shell 10 and electrically connected with the circuit board assembly 11, the other end is located outside the shell 10 and has a charging connector 50 and is received in the receiving groove 103. This can provide more versatile applications, so that users do not need to prepare electrical transmission lines to use the folded charger 9 for charging electronic devices. And the retractable charging cord 5 has the advantages of being easy to pull out for use and automatically retracting when not in use, so that one end with the charging connector 50 is received in the receiving groove 103. Preferably, the retractable charging cord 5 can be designed with a stress relief structure to relieve the stress between the charging connector 50 and the wire, avoiding damage to the wire due to bending or pulling. In addition, the charging connector 50 can also be selected from one of USB-A, Mini USB, Micro USB, USB Type-C or Lighting specifications or a combination thereof, to meet the charging needs of various electronic devices. In Figure 6 In addition, in terms of storage and fixation, the retractable charging cord 5 can be stored and fixed in the receiving groove 103 by magnetic attraction, or the width of the receiving groove 103 can be adjusted to clamp and fix the retractable charging cord 5 to form storage, etc.

[0040] In summary, the folding charger is designed by a novel mechanism, so that the plug assembly does not need to be embedded in the charger body when it is pivoted to be parallel or perpendicular to the first side, thereby maintaining the advantage of small size, and providing the user with the convenience of carrying and using. At the same time, the folding charger also has good electrical conduction stability. Through the structure design of the conductive adapter spring, the pair of third pins and the pair of second pins of the bracket form stable assembly contact, and the pair of first pins can contact the pair of circuit board conductive springs when the plug assembly is pivoted to be perpendicular to the first side, thereby constructing a complete conductive path from the plug to the circuit board assembly, effectively eliminating the problem of poor contact of the charger. Further, the utility model also proposes many additional detailed technical features, such as the folding charger, which is realized by the cooperation of the shaft spring, the gland and the shaft of the bracket. And the gland can be assembled by screw locking to improve the bearing capacity of the shaft spring. In order to enhance the stability of the plug assembly in the perpendicular state of the first side, the assembly part can be provided with the convex rib to be clamped with the positioning hole of the inner cover. In addition, in order to improve the combination stability of each element and the pair of conductive adapter springs, the clamping parts can be provided with the pair of clamping pieces arranged in mirror image and gradually decreasing in distance towards the inner cover, so as to form a hook-like clamping and fixing effect relative to the pair of third pins. Or the pair of conductive fixing pieces are screws. In consideration of process convenience and electrical conduction certainty, the pair of first pins and the pair of second pins are conductive columns penetrating the pair of struts. In order to improve the structural stability under pivoting operation, the outer cover and the inner cover can be fixed by the first combination part and the second combination part of the corresponding groove and the convex block structure. In consideration of the applicability of the folding charger, it can further include the retractable charging line stored in the housing storage slot, so as to provide diversified charging use mode. Finally, the charging interface or the charging connector can be selected from USB-A, Mini USB, Micro USB, USB Type-C or Lighting specification to meet the charging needs of most electronic devices today.
