The gear 5 29 is coaxially fixedly connected to the input shaft of the three-phase brushless generator 32. The three-phase brushless generator 32 is installed on the upper surface of the lower base plate 12.

[0029] In specific use, the wearable electromagnetic high-efficiency sole energy capture device described in this embodiment can be set in public areas such as roads and stairs; it can also be set on the sole of the human foot, such as inside the sole.

[0030] like Figure 1 As shown, in order to limit the pressure plate 1, the guide rod 16 in this embodiment is a plug screw, which passes through the cylindrical tube 14 from bottom to top, and its nut is limited by the lower surface of the lower base plate 12, and the middle part of the screw rod is gap-fitted with the cylindrical tube 14, and the threaded part at the end of the screw rod is threadedly connected with the pressure plate 1, so as to limit the pressure plate 1 in the vertical direction and prevent the pressure plate 1 from scattering or detaching.

[0031] The specific working principle of this embodiment is as follows: Compression stage: When the pedal plate 1 in this embodiment is subjected to human body pressure, the guide rod 16 cooperates with the cylindrical tube 14 to guide the pedal plate 1 downward in the vertical direction. At the same time, the scissor mechanism 2 on both sides of the pedal plate 1 is squeezed in the vertical direction, and the scissor mechanism 2 gradually extends in the horizontal direction ( Figure 2 As shown in the figure, it is stretched to the right), and under the cooperation of the linear bearing 10 and the horizontal optical axis 11, the push block 7 is driven to move to the right along the horizontal direction on the upper surface of the lower base plate 12 (as shown in the figure). Figure 2 At the same time, since the movable pulley 1 8 and the movable pulley 2 9 are rotatably mounted on the push block 7, the movable pulley 1 8 and the movable pulley 2 9 also move to the right in the horizontal direction. Since one end of the pulley line 24 is fixed on the boss 15, the body of the pulley line 24 is wound on the annular track 23. At this time, due to the movement of the push block 7, the distance between the movable pulley 1 8, the movable pulley 2 9 and the fixed pulley 2 19 is lengthened, and the pulley line 24 is pulled out from the annular track 23, and the annular track 23 rotates and drives the gear 1 20 to rotate; due to the generation The inner end of the spring 21 is engaged with the slot 51 of the concave optical axis 5, and the outer end of the spring 21 is engaged with the stopper 231 fixed inside the annular track 23. When the gear 20 rotates, the outer end of the spring 21 rotates and the inner end is relatively fixed, and the spring 21 is tightened to store energy; the one-way bearing 27 is in a locked state, and the gear 20 drives the gear 4 28 and the gear 3 26 to rotate coaxially through the gear 2 25, and the gear 4 28 drives the gear 5 29 and the input shaft of the three-phase brushless generator 32 to rotate coaxially to achieve power generation.

[0032] Reset stage: when the external force on the pressure plate 1 is removed, the spring 21 releases energy. Since the inner end of the spring 21 is relatively fixed, the outer end of the spring 21 pushes the stopper 231 to rotate in the opposite direction, thereby driving the gear 1 20 to rotate in the opposite direction. At this time, the body of the pulley line 24 is rewound on the annular track 23; the gear 1 20 rotates in the opposite direction, driving the gear 3 26 to rotate through the gear 2 25, the one-way bearing 27 is in a disengaged state, and the gear 4 28 does not rotate with the gear 3 26, but rotates with the three-phase inertia under the action of inertia. The brush motor 32 and the gear five 29 continue to rotate for a while (the same direction as in the compression stage); at the same time, since the pulley line 24 is retracted again, the distance between the movable pulley 1 8, the movable pulley 2 9 and the fixed pulley 2 19 is shortened, the movable pulley 1 8, the movable pulley 2 9 moves and drives the push block 7 to reset in the horizontal direction, the push block 7 moves in the horizontal direction and pulls the scissor-fork mechanism 2 on both sides to contract in the horizontal direction, after the scissor-fork mechanism 2 returns to its original state, the clockwork 21 returns to its original state, and the pressure plate 1 returns to its initial position.

[0033] like Figure 3 As shown, in order to facilitate the installation of gear three 26 and gear four 28, the upper cover plate 3 has a mounting hole 301 that is connected and matched with the bearing seat of the one-way bearing 27.

[0034] like Figure 4 As shown, this embodiment provides an installation method for movable pulley 1 8 and movable pulley 2 9, specifically: a support plate 701 is supported on the upper surface of the push block 7, and shaft 1 and shaft 2 are provided between the upper surface of the push block 7 and the support plate 701, which are respectively rotatably matched with movable pulley 1 8 and movable pulley 2 9.

[0035] Furthermore, the upper surface of the lower base plate 12 is provided with a slide groove 121 which is slidably matched with the bottom of the push block 7. The slide groove 121 in this embodiment is arranged along the sliding direction of the push block 7 and is guided and matched with the push block 7.

[0036] In a preferred embodiment, since the vibration of this embodiment during use may cause the body of the pulley line 24 to move in the annular track 23, a semicircular baffle 14 is provided on the lower surface of the upper cover plate 3 of this embodiment, which is gap-matched with the annular track 23. The semicircular baffle 14 cooperates with the annular track 23 to ensure that the pulley line 24 can be smoothly released or reeled in the track.

[0037] Similarly, in order to prevent the pulley line 24 from moving on the fixed pulley 19 , a semicircular baffle 131 is provided on the T-shaped optical axis 13 to be in clearance with the fixed pulley 19 .

[0038] Furthermore, the present embodiment also provides a method for installing the three-phase brushless generator 32 , specifically: the casing of the three-phase brushless generator 32 is installed on the upper surface of the lower base plate 12 through a connecting column 321 .

[0039] like Figure 5 As shown, this embodiment also provides a method for installing the gear 5 29, specifically: a D-shaped hole 30 is opened in the center of the gear 5 29, and the D-shaped hole 30 is matched with the D-shaped shaft 31 of the three-phase brushless generator 32. The D-shaped shaft 31 in this embodiment is the input shaft of the three-phase brushless generator 32.

[0040] Preferably, flange bearings are provided on one side of the gear 1 20 and the gear 2 25. The gear 1 20 and the gear 2 25 are respectively arranged on the lower surface of the upper cover plate 3 through corresponding flange bearings.

[0041] Furthermore, rolling bearings are respectively provided at the hinge points of the scissor arms at the head and tail of the scissor mechanism 2 to convert the contact relationship of the hinge points into rolling friction, thereby reducing frictional resistance and improving the smoothness of the extension and retraction of the scissor mechanism 2.

[0042] The above is only a specific implementation of the present invention, which enables those skilled in the art to understand or implement the present invention. Although detailed descriptions are given with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments, and they should all be covered by the protection scope of the claims.
