[0038] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0039] Please refer to Figure 1-Figure 7 The charger 100 provided in the embodiment of the utility model can solve the above problems, which will be described in detail below.

[0040] refer to Figure 1 and Figure 2 The charger 100 includes a housing 110, an electrical connector 120 and an elastic member 130; wherein the electrical connector 120 is rotatably disposed on the housing 110, and the elastic member 130 is rotatably connected to the rear end of the electrical connector 120;

[0041] The elastic member 130 is used to provide two pushing forces in opposite directions when the electrical connector 120 rotates to a critical position.

[0042] It is worth noting that the electrical connector 120 has a certain rotation stroke relative to the housing 110. When the electrical connector 120 rotates to one of the extreme positions, it can be easily stored; when the electrical connector 120 rotates to the other extreme position, it can perform power input or output operations. The critical rotation position can be regarded as the midpoint position of the rotation stroke of the electrical connector 120.

[0043] When the charger 100 is working, the electrical connector 120 can be rotated, and the elastic member 130 can be compressed or stretched during the rotation. By connecting the elastic member 130 to the tail end of the electrical connector 120, the space on both sides of the electrical connector 120 can be optimized, thereby improving the space utilization of the charger 100 and helping to reduce the overall volume of the charger 100.

[0044] refer to Figure 1 and Figure 2 The charger 100 further includes a connecting wire 150, which is electrically connected to the electrical connector 120. In order to ensure communication stability, the connecting wire 150 can be a soft flat cable with a certain width, and the soft material will not be easily damaged due to the rotation of the electrical connector 120.

[0045] Of course, in order to simplify the assembly steps, the elastic member 130 can be made of a conductive material, and one end of the elastic member 130 is electrically connected to the tail end of the electrical connector 120. In addition, the charger 100 also includes a circuit board 140, and one end of the elastic member 130 away from the electrical connector 120 can be electrically connected to the circuit board 140. Specifically, the material of the elastic member 130 can be silver, copper, gold or aluminum, etc., and the specific material type is not limited, as long as it can conduct electricity to the electrical connector 120.

[0046] refer to Figure 3 The housing 110 includes a shell 111 and a shell bracket 112. The shell 111 is formed with a bracket opening 1111. The shell bracket 112 is embedded in the bracket opening 1111. The outer side of the shell bracket 112 is formed with a receiving groove 1101. At least a part of the electrical connector 120 is received in the receiving groove 1101.

[0047] It should be noted that the volume of the electrical connector 120 should be smaller than the volume of the receiving groove 1101, so that the electrical connector 120 can be completely received in the receiving groove 1101, and the electrical connector 120 is prevented from protruding out of the receiving groove 1101 in the received state, thereby protecting the electrical connector 120 in the received state and preventing it from being damaged during transportation and storage.

[0048] During the assembly process, the housing 111 is a hollow piece, so that the elastic piece 130 and the circuit board 140 can be accommodated inside the housing 111, and the housing 111 shields and protects them to ensure safety during the charging process. At the same time, in order to ensure stable support for the electrical connector 120, the housing bracket 112 is embedded by opening the bracket opening 1111 to ensure that the relative position of the housing bracket 112 and the housing 111 will not change easily during the rotation of the electrical connector 120.

[0049] refer to Figure 4 and Figure 5 The shell support 112 includes a first frame body 1121 and a second frame body 1122 connected to each other. A rotation hole 1123 is formed between the first frame body 1121 and the second frame body 1122 , and the electrical connector 120 is rotatably connected to the rotation hole 1123 .

[0050] Specifically, the two sides of the electrical connector 120 are provided with rotating shafts 122, which are engaged with the rotating holes 1123. During the molding process, the side of the first frame 1121 close to the second frame 1122 can be recessed inward to form a semicircular groove, and the side of the second frame 1122 close to the first frame 1121 can be recessed inward to form a semicircular groove, and the two semicircular grooves correspond to each other and enclose the rotating hole 1123.

[0051] Of course, in order to prevent the first frame 1121 and the second frame 1122 from being easily separated, the two can be detachably connected or fixedly connected, and the specific connection methods include but are not limited to: threaded connection, snap connection, bonding or welding, etc. In addition, in order to improve the molding efficiency, the first frame 1121 and the second frame 1122 can also be integrally molded.

[0052] It should be noted that in order to ensure that the tail end of the electrical connector 120 can be smoothly connected to the elastic member 130, a hollow hole 1124 is provided near the tail end of the electrical connector 120 on the first frame 1121 and the second frame 1122. The hollow hole 1124 is used to avoid the tail end of the electrical connector 120 during the rotation process.

[0053] It is worth noting that the first end of the electrical connector 120 can be a type-C, USB3.2, Lightning or other interface, and the specific interface type is not limited; it can also have multiple interface types at the same time, and then select a matching interface according to the interface type of the device to be charged.

[0054] refer to Figure 6The elastic member 130 includes a first sub-segment 131, a second sub-segment 132 and a third sub-segment 133 which are connected in sequence. The first sub-segment 131 and the third sub-segment 133 are arranged in parallel. The second sub-segment 132 is inclined relative to the first sub-segment 131 and the third sub-segment 133. The first sub-segment 131 is rotatably connected to the tail end of the electrical connector 120.

[0055] In this embodiment, when the electrical connector 120 is flipped under the action of external force, the second sub-segment 132 can be compressed by the first sub-segment 131, so that the distance between the two sides of the second sub-segment 132 and the first sub-segment 131 and the third sub-segment 133 is reduced, and the angle between the two ends of the second sub-segment 132 and the first sub-segment 131 and the third sub-segment 133 is reduced.

[0056] It is worth noting that in the present embodiment, the electrical connector 120 compresses the elastic member 130 during the rotation process, and when the rotation limit position is reached, the elastic member 130 will relax and reset to provide tension to the electrical connector 120; in other embodiments of the present invention, the electrical connector 120 can also stretch the elastic member 130 during the rotation process, and when the rotation limit position is reached, the elastic member 130 will contract and reset to provide pulling force to the electrical connector 120.

[0057] In addition, in order to improve the elastic potential energy storage capacity of the elastic member 130, a first elastic ring 134 may be formed at the connection between the first sub-segment 131 and the second sub-segment 132, and a second elastic ring 135 may be formed at the connection between the second sub-segment 132 and the third sub-segment 133. By forming the elastic ring, the extreme position of the elastic member 130 during the compression process is ensured to prevent the elastic member 130 from breaking through the compression limit and being easily damaged.

[0058] It is worth noting that the elastic ring can be a closed circle or an open spiral structure, and the specific structural shapes of the two elastic rings are not limited.

[0059] It should be noted that the elastic member 130 may also be a spring, and the electrical connector 120 may also directly compress the spring during the rotation process; when the rotation reaches the limit position, the spring may reset itself to support the electrical connector 120 .

[0060] refer to Figure 5 , a limiting hole 121 may be provided at the tail end of the electrical connector 120, and one end of the elastic member 130 close to the electrical connector 120 is accommodated in the limiting hole 121. Specifically, at least part of the first subsection 131 is accommodated in the limiting hole 121.

[0061] In this embodiment, the opening direction of the limiting hole 121 is perpendicular to the extension direction of the electrical connector 120, that is, the extension direction of the first sub-segment 131 is also perpendicular to the extension direction of the electrical connector 120, which can prevent the elastic frame from twisting when the electrical connector 120 drives the elastic member 130 to rotate.

[0062] refer to Figure 2 and Figure 7 The housing 110 further includes an inner bracket 113, and the end of the elastic member 130 away from the electrical connector 120 can be rotatably connected to the inner bracket 113. In addition, the circuit board 140 can be detachably connected to the inner bracket 113, and the inner bracket 113 is used to fix and support the circuit board 140. When the circuit board 140 is damaged, the circuit board 140 can be directly disassembled and replaced, and the position accuracy of the reinstalled circuit board 140 can be guaranteed.

[0063] In addition, the housing 110 further includes a limit block 114 , which is connected to the inner bracket 113 and forms a limit cavity 119 with the inner bracket 113 . An end of the elastic member 130 away from the electrical connector 120 is accommodated in the limit cavity 119 and abuts against the inner bracket 113 and the limit block 114 .

[0064] In this embodiment, the stopper 114 is L-shaped, one end of which is connected to the inner bracket 113, and the other end is parallel to the plate surface of the connected inner bracket 113, thereby forming a stopper cavity 119 with an opening. A portion of the third sub-segment 133 of the elastic member 130 can be placed in the stopper cavity 119 through the opening, and both ends of the third sub-segment 133 protrude from the stopper 114, and by abutting against the stopper 114 and the inner bracket 113, the third sub-segment 133 can be stably supported during the rotation process.

[0065] In summary, the charger 100 provided in the embodiment of the present invention has at least the following advantages:

[0066] (1) By connecting the elastic member 130 to the rear end of the electrical connector 120, the charger 100 can optimize the space on both sides of the electrical connector 120, thereby improving the space utilization of the charger 100 and helping to reduce the overall volume of the charger 100.

[0067] (2) The charger 100 can make the elastic member 130 of a conductive material so that the elastic member 130 is electrically connected to the electrical connector 120, thereby simplifying the assembly steps and reducing or eliminating the arrangement of the connecting wire 150 between the circuit board 140 and the electrical connector 120.

[0068] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
