[0026] To enable those of ordinary skill in the art to more clearly understand the purpose, technical solution and advantages of the present utility model, the following further elaborates the present utility model in conjunction with the accompanying drawings and embodiments.

[0027] The present utility model provides a folding charger. As Figures 1-3 shown, in an embodiment of the present utility model, the folding charger includes a housing 100, a charging main board (not shown), a charger output interface 200, and a folding hardware pin connection and conduction structure. The charging main board is electrically connected to the folding hardware pin connection and conduction structure and the charger output interface 200 respectively.

[0028] The present utility model also provides a folding hardware pin connection and conduction structure, which is applied to the above-mentioned folding charger.

[0029] As Figures 4-9 shown, in an embodiment of the present utility model, the folding hardware pin connection and conduction structure includes a fixing member 10, two elastic pieces 40, two hardware pins 20, and a rotating shaft 30. The hardware pins 20 are fixed on the rotating shaft 30. The rotating shaft 30 is installed on the fixing member 10 in a manner that can rotate relative to the fixing member 10. The two elastic pieces 40 are correspondingly arranged on both sides of the rotating shaft 30. A connecting portion 21 coaxial with the rotating shaft 30 is formed by bending the tail end of the hardware pin 20. The elastic piece 40 is connected to the connecting portion 21 and fixes the hardware pin 20 in an open state or a stored state.

[0030] In the folding hardware pin connection and conduction structure of this embodiment, the two elastic pieces 40 are correspondingly arranged on both sides of the rotating shaft 30. A connecting portion 21 coaxial with the rotating shaft 30 is formed by bending the tail end of the hardware pin 20. By connecting the elastic piece 40 to the connecting portion 21, the contact point between the hardware pin 20 and the elastic piece 40 is set on both sides of the rotating shaft 30, so that the space required for the rotating shaft 30 to rotate is no longer restricted by the position of the contact point between the hardware pin 20 and the elastic piece 40. The overall thickness L of the folding hardware pin connection and conduction structure can be reduced to less than 7.8 mm, which can effectively reduce the product space occupied by the folding hardware pin connection and conduction structure and is conducive to the miniaturization design of the charger product.

[0031] The fixing member 10 includes a fixing base 11 and a pressing plate 12. The fixing base 11 and the pressing plate 12 clamp and fix the hardware pin 20 and the elastic piece 40 on the fixing base 12. The fixing base 11 and the pressing plate 12 are connected and fixed by screws, snap connections or other means.

[0032] The hardware pin 20 is formed by stamping stainless steel, copper alloy or titanium alloy. The cross-section of the connecting portion 21 is a square with a size of 1.5mm * 1.5mm. The elastic piece 40 includes an upper contact portion 41 and a lower contact portion 42. The upper contact portion 41 and the lower contact portion 42 are parallel to each other. The connecting portion 21 is clamped between the upper contact portion 41 and the lower contact portion 42. Any two opposite side surfaces of the upper contact portion 41 and the lower contact portion 42 are in contact and cooperation with the connecting portion 21 to fix the hardware pin 20 in the open state or the storage state. Since the cross-section of the connecting portion 21 is square and the upper contact portion 41 and the lower contact portion 42 are parallel to each other, during the 0-90° rotation of the hardware pin 20, two opposite side surfaces of the connecting portion 21 are always in contact and cooperation with the upper contact portion 41 and the lower contact portion 42 under the clamping of the upper contact portion 41 and the lower contact portion 42, so as to fix the hardware pin 20 in the open state or the storage state.

[0033] The elastic piece 40 includes a side contact portion 43, and the side contact portion 43 is in contact and cooperation with the end of the connecting portion 21. In this embodiment, the side contact portion 43 is fixedly connected to the lower contact portion 42; in other embodiments, the side contact portion 43 can also be fixedly connected to the upper contact portion 41.

[0034] It should be noted that Figures 1-3 The folding charger in the illustrated embodiment is a regular charger, and the present invention also provides a US-standard folding charger, as Figure 9 shown. The difference between the US-standard folding charger and the folding charger in the Figures 1-3 illustrated embodiment is that: a round hole 22 is provided on the hardware pin 20 of the folding hardware pin connection and conduction structure.

[0035] The beneficial technical effects of the present invention are as follows:

[0036] 1. In the folding hardware pin connection and conduction structure of the present invention, two elastic pieces are correspondingly arranged on both sides of the rotation axis. The tail end of the hardware pin is bent to form a connecting portion coaxial with the rotation axis. By connecting the elastic piece with the connecting portion, the contact points between the hardware pin and the elastic piece are arranged on both sides of the rotation axis, so that the space required for the rotation axis to rotate is no longer restricted by the positions of the contact points between the hardware pin and the elastic piece, which can effectively reduce the product space occupied by the folding hardware pin connection and conduction structure and is beneficial to the miniaturization design of the charger product.

[0037] 2. The cross-section of the connecting part of the metal pin is square, and the upper contact part and the lower contact part of the elastic piece are parallel to each other. During the rotation of the metal pin within the range of 0 to 90°, under the clamping of the upper contact part and the lower contact part, two opposite side faces of the connecting part always contact and cooperate with the upper contact part and the lower contact part correspondingly, so as to fix the metal pin in the open state or the storage state.

[0038] 3. The connecting part of the metal pin contacts and cooperates with the upper contact part, the lower contact part and the side contact part of the elastic piece respectively. There are up to three contact points between the metal pin and the elastic piece. The multi-point contact can make the conduction between the metal pin and the elastic piece more reliable and stable. At the same time, it can also meet the design requirements of a larger output power of the charger.

[0039] The above are only the preferred embodiments of the present invention, rather than any form of limitation to the present invention. Those skilled in the art can make various equivalent changes and improvements on the basis of the above embodiments. Any equivalent changes or modifications made within the scope of the claims shall fall within the protection scope of the present invention.
