[0045] like Figure 1-3 A plug folding charger is shown, and the plug folding charger includes a main shell 1, a charging mainboard 2, a capacitor 3 and a plug 4. A charging hole is provided on the first surface of the main shell 1. The charging mainboard 2 is arranged in the main shell 1, and a plurality of charging interfaces are provided on the charging mainboard 2, and the charging interfaces are embedded in the charging hole. The capacitor 3 is arranged on the charging mainboard 2. The plug 4 is pivotally connected to the second surface of the main shell 1, and the plug 4 is electrically connected to the charging mainboard 2. Specifically, the overall shape of the main shell 1 is approximately a flat rectangular parallelepiped, the first surface is one of the side surfaces, and the second surface is the back of the main shell 1, that is, the plug 4 is pivotally connected to the back of the main shell 1.

[0046] In this embodiment, the plug 4 is arranged to be pivotally connected to the main housing 1, and the plug 4 can be swung to be perpendicular to the main housing 1 or close to the main housing 1. When charging is required, the plug 4 is manually swung to a position perpendicular to the main housing 1; after charging is completed, or when the plug needs to be packed and carried, the plug 4 can be manually swung to a position close to the main housing 1. In this way, the position of the plug 4 is changed by swinging the plug 4 in the utility model. When the plug 4 is swung close to the main housing 1, the thickness of the main housing 1 can be reduced, and the volume occupied by the main housing 1 can be reduced, which is convenient for packing and carrying, and has better portability.

[0047] In some articulated embodiments, such as Figure 4 As shown, the second surface of the main housing 1 is provided with a pivoting ear 11, and a first positioning mechanism is provided on the side of the pivoting ear 11. The plug 4 is pivoted to the pivoting ear 11, and a second positioning mechanism is provided on the plug 4. The second positioning mechanism and the first positioning mechanism are positioned and matched to position the charging position and the folding position. In this embodiment, the pivoting ear 11 and the plug 4 are pivoted, and each is provided with a first positioning mechanism and a second positioning mechanism. Through the positioning and matching of the first positioning mechanism and the second positioning mechanism, the plug 4 is positioned in the charging position and the folding position. The charging position is preferably a position perpendicular to the main housing 1, and the folding position is a position close to the main housing 1.

[0048] Furthermore, if Figure 4 As shown, the first positioning mechanism includes a charging recess 111 and a folding recess 112. The second positioning mechanism is an elastic member 4111, on which a protrusion is provided, which swings with the plug 4 and can at least move back and forth between the charging recess 111 and the folding recess 112. In the first positioning mechanism, the charging recess 111 is used to limit the position of the protrusion, so that the plug 4 is kept in the charging position, and the folding recess 112 is used to limit the position of the protrusion, so that the plug 4 is kept in a position close to the main housing 1. After the plug 4 is positioned in the charging position and the folding position, the charging recess 111 and the folding recess 112 increase the resistance to the swing of the plug 4, which can limit the free rotation of the plug 4 to a certain extent, so that the plug 4 can be kept in the charging position when charging and can be kept in the folding position when carrying.

[0049] Furthermore, if Figure 4 As shown, the first positioning mechanism further includes an arc groove 113, and the charging recess 111 and the folding recess 112 are arranged in the arc groove 113. The protrusion extends into the arc groove 113, and the protrusion moves along the arc groove 113 as the plug 4 swings. When the plug 4 swings, the protrusion moves along the arc groove 113, and the arc groove 113 guides the protrusion to move smoothly.

[0050] In some other embodiments of the first positioning mechanism and the second positioning mechanism, the first positioning mechanism may be two first magnetic blocks, the positions of the two first magnetic blocks are arranged corresponding to the aforementioned charging recess 111 and the folding recess 112, and the second positioning mechanism may be a second magnetic block, and the second magnetic block is arranged on the plug 4.

[0051] The second positioning mechanism can also be a ball-end screw, which cooperates with the aforementioned charging recess 111 and folding recess 112 at the same time.

[0052] In some embodiments where the plug 4 is pivotally connected to the main housing 1, two spaced-apart pivot ears 11 are provided on the second surface of the main housing 1. Specifically, two pivot ears 11 are provided on the back of the main housing 1, the side of the pivot ear 11 close to the other pivot ear 11 is the inner side, and the side of the pivot ear 11 away from the other pivot ear 11 is the outer side, and the aforementioned first positioning mechanism is specifically located on the outer side of the pivot ear 11.

[0053] like Figure 3 , Figure 4 As shown, a pin 43 is provided at one end of the plug 4, and a shaft 42 is provided at the other end of the plug 4. The shaft 42 is located between the two pivoting ears 11, and the two ends of the shaft 42 are respectively pivoted to the two pivoting ears 11. The plug 4 is pivoted to the pivoting ears 11 through the shaft 42, thereby realizing the pivot connection between the plug 4 and the main housing 1.

[0054] In some specific embodiments of the plug 4, such as Figure 3 , Figure 4 As shown, the plug 4 includes a plug housing 41, a rotating shaft 42 and a pin 43. The pin 43 is arranged at the front end of the plug housing 41. The rear end of the plug housing 41 is provided with a sleeve, and the rotating shaft 42 is passed through the sleeve. The plug housing 41 is mounted by the sleeve at its rear end.

[0055] Furthermore, if Figure 4 , Figure 5 As shown, the plug housing 41 includes a first housing 411 and a second housing 412. A first arc-shaped portion 4112 is provided at the rear end of the first housing 411. A second arc-shaped portion 4121 is provided at the rear end of the second housing 412. The first housing 411 and the second housing 412 are snap-fitted and connected, and the first arc-shaped portion 4112 and the second arc-shaped portion 4121 are snap-fitted to form a sleeve. The plug housing 41 includes two first housings 411 and second housings 412 that are snap-fitted and connected, and the sleeve is formed by snapping the first arc-shaped portion 4112 at the rear end of the first housing 411 and the second arc-shaped portion 4121 at the rear end of the second housing 412.

[0056] Furthermore, if Figure 4 , Figure 5 and Figure 6As shown, a positioning protrusion 4113 is provided at the end of the first arc-shaped portion 4112, and a positioning hole 4122 is provided at the end of the second arc-shaped portion 4121. By providing the positioning protrusion 4113 at the first arc-shaped portion 4112 and providing the positioning hole 4122 at the end of the second arc-shaped portion 4121, when the first shell 411 and the second shell 412 are buckled, the first arc-shaped portion 4112 and the second arc-shaped portion 4121 are butted, and the positioning protrusion 4113 is embedded in the positioning hole 4122. After being positioned by the positioning protrusion 4113 and the positioning hole 4122, the stability of the connection between the end of the first arc-shaped portion 4112 and the end of the second arc-shaped portion 4121 is improved, the end of the first arc-shaped portion 4112 and the end of the second arc-shaped portion 4121 are prevented from being misaligned, and the strength of the sleeve is improved.

[0057] In some embodiments of the rotating shaft 42, such as Figure 4 , Figure 5 As shown, a limiting groove 4114 is provided in the plug housing 41, and the limiting groove 4114 extends into the sleeve. The limiting groove 4114 can be specifically provided in the aforementioned first housing 411, or in the aforementioned second housing 412.

[0058] like Figure 4 , Figure 5 As shown, the rotating shaft 42 includes a first shaft section 421, a second shaft section 422 and an elastic connector 423. The first shaft section 421 and the second shaft section 422 are arranged at intervals at both ends of the sleeve. The first shaft section 421 and the second shaft section 422 are coaxially arranged. The elastic connector 423 is arranged in the limiting groove 4114. The two ends of the elastic connector 423 are respectively connected to the first shaft section 421 and the second shaft section 422. In this embodiment, the rotating shaft 42 includes three parts, two coaxially arranged first shaft sections 421 and second shaft sections 422, and the first shaft section 421 and the second shaft section 422 are connected by the elastic connector 423. Under the action of external axial pressure, the first shaft section 421 and the second shaft section 422 can both be pushed along the axial direction. After the pressure is removed, the first shaft section 421 and the second shaft section 422 return to the initial position. In this way, when installing the plug 4, the first shaft segment 421 and the second shaft segment 422 can be pressed from both sides respectively, so that the first shaft segment 421 and the second shaft segment 422 are retracted into the sleeve, and then the sleeve is moved between the two pivot ears 11. When the sleeve is aligned with the two pivot ears 11, the first shaft segment 421 and the second shaft segment 422 are acted upon by the elastic force of the elastic connecting member 423, and the first shaft segment 421 and the second shaft segment 422 are pivotally connected to the two pivot ears 11 respectively.

[0059] Specifically, the elastic connecting member 423 is a U-shaped spring sheet, and two ends of the U-shaped spring sheet are connected to the first shaft section 421 and the second shaft section 422 respectively.

[0060] In some embodiments of the main housing 1, as Figure 1 , Figure 2As shown, a limiting step 12 is provided on the second surface of the main housing 1 near the pivot ear 11. The end of the plug 4 near the main housing 1 is aligned with the limiting step 12, and the plug 4 is perpendicular to the main housing 1. By providing the limiting step 12 on the back of the main housing 1, the limiting step 12 limits the charging position of the plug 4, and prevents the plug 4 from swinging excessively, so that the plug 4 can be accurately swung to a position perpendicular to the main housing 1.

[0061] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
