[0034] Example 1

[0035] A UK-standard folding PIN structure includes a housing, a first PIN, and two second PINs hinged to the housing. The housing front is provided with a first PIN receiving slot and two second PIN receiving slots. The first PIN receiving slot is located in the upper portion of the housing, while the second PIN receiving slots are symmetrically located on either side of the lower portion.

[0036] Specifically, a first rotating member is rotatably connected in the first PIN receiving slot. A second rotating member is rotatably connected in each second PIN receiving slot. The first PIN is rotatably set on the shell through the first rotating member; the two second PINs are rotatably set on the shell through the two second rotating members. Two groups of transmission members are provided between the first rotating member and the two second rotating members, and the transmission members are symmetrically arranged on both sides of the first PIN. Each group of transmission members includes a tension spring, a first eccentric member and a second eccentric member. One end of the first eccentric member is connected to the first rotating member and can make a circular motion around the first rotating member. One end of the second eccentric member is connected to the first rotating member and can make a circular motion around the second rotating member. The end of the first eccentric member away from the first rotating member is connected to the end of the second eccentric member away from the second rotating member through a tension spring. Rotating the first PIN or any second PIN will drive the other PINs to rotate in the same direction and by the same angle.

[0037] Rotating the first pin 90° counterclockwise to a vertical position causes the first rotating member and the first eccentric member to rotate synchronously, compressing the spring and pushing the second eccentric member to rotate counterclockwise by the same angle. This in turn causes the second rotating member and the second pin to rotate counterclockwise by 90° until they reach a vertical position. The spring returns to its natural position, completing the pin's unfolding. Conversely, rotating the first pin 90° clockwise to fold it up causes the second pin to rotate 90° clockwise, driven by the first rotating member, the second rotating member, and the transmission member, completing the pin's folding action.

[0038] Example 2

[0039] Please refer to Figure 1-5 The UK-standard folding PIN structure shown here includes a housing 1, a first PIN 2, and two second PINs 3, which are hinged to the housing 1. The housing 1 is provided with a first PIN receiving slot 11 and two second PIN receiving slots 12. The first PIN receiving slot 11 is located on the back of the housing 1; the two second PINs 3 are symmetrically located on the front. A rotation slot 13 is provided on the top of the housing 1, connecting to the first PIN receiving slot 11. The first PIN 2 rotates within the rotation slot 13, rotating from the back of the housing 1 to the front, where it becomes vertically aligned with the front.

[0040] Specifically, a first screw rod 4 is rotatably connected in the first PIN receiving slot 11. A second screw rod 5 is rotatably connected in each second PIN receiving slot 12. Figure 7-8The British standard folding PIN plug shelling structure shown. The first PIN 2 is rotatably set on the housing 1 through the first screw 4; the two second PINs 3 are rotatably set on the housing 1 through the two second screws 5. Two groups of transmission parts are provided between the first screw 4 and the two second screws 5, and the transmission parts are symmetrically arranged on both sides of the first PIN 2. Each group of transmission parts includes a first gear 6, a second gear 7, a tension spring 10, a first eccentric member 8 and a second eccentric member 9. The first screw 4 is provided with meshing teeth that match the inner teeth of the first gear 6. The first screw 4 is connected to the inner meshing of the first gear 6 through the meshing teeth, and the first screw 4 can drive the first gear 6 to rotate synchronously. The second gear 7 is externally meshed with the first gear 6 and the gear ratio of the first gear 6 to the second gear 7 is 1:3. The first eccentric member 8 is provided on the second gear 7 and is connected to the first screw 4 through the second gear 7, the first gear 6 and the first screw 4. The second eccentrics 9 of the two transmission components are connected to the two second screws 5, respectively. The distance from the connection between the tension spring 10 and the first eccentric 8 to the center of rotation of the first eccentric 8 is equal to the distance from the connection between the tension spring 10 and the second eccentric 9 to the center of rotation of the second eccentric 9, ensuring that the first and second eccentrics 8 and 9 rotate at equal angles. Rotating the first pin 2 or any second pin 3 can cause the other pins to flip.

[0041] The implementation method of turning the PIN of the British standard folding PIN pin structure from the folded state to the vertical state is as follows:

[0042] An external force is applied to flip the first pin 2 clockwise, driving the first gear 6 and first screw 4 to rotate synchronously. Simultaneously, the first gear 6 drives the second gear 7 counterclockwise, which in turn drives the first eccentric 8 to rotate synchronously. As the first eccentric 8 rotates counterclockwise, one end of the tension spring 10 follows its movement. The tension spring 10 compresses, pushing the second eccentric 9 counterclockwise, which in turn drives the second screw 5 and the second pin 3 to rotate. When the first pin 2 flips to its front, it reaches a vertical position, rotating 270° clockwise. Due to the transmission ratio, the 270° clockwise rotation of the first gear 6 drives the second gear 7 counterclockwise by 90°. The second eccentric 9, driven by the tension spring 10, also rotates counterclockwise by 90°, returning the tension spring 10 to its natural position. Consequently, the second eccentric 9 drives the second screw 5 and the second pin 3 to rotate counterclockwise by 90°, returning them to their normal position. At this point, the first and second pins 2 and 3 flip from their folded position to a vertical position, ready for charging.

[0043] Similarly, the principle of flipping the PIN from the vertical state to the folded state can be deduced from the above-mentioned motion process of unfolding the PIN.

[0044] Example 3

[0045] like Figure 8-9As shown, the only difference between this embodiment and embodiment 2 is that: in the PIN folded state, the ends of the first screw 4 and the second screw 5 connected to the tension spring 10 are both at the upper left of their motion circular trajectory.

[0046] Compared with Example 2, the PIN of the British standard folding PIN pin structure can be changed from the folded state to the vertical state by the following methods:

[0047] Apply external force to rotate the second pin 3 counterclockwise 90°, driving the second screw 5 and the second eccentric 9 to rotate synchronously. During this rotation, the tension spring 10 is stretched at one end, causing the second gear 7 to rotate counterclockwise 90°, allowing the spring 10 to return to its free state. This in turn drives the first gear 6 clockwise 270°, which in turn drives the first screw 4 and the first pin 2 clockwise 270°. At this point, both the first and second pins 2 and 3 are flipped to an upright position on the front of the housing 1, ready for charging and use.

[0048] Similarly, the principle of flipping the PIN from the vertical state to the folded state can be deduced from the above-mentioned motion process of unfolding the PIN.

[0049] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
