[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0023] like Figures 1 to 6 As shown, the present invention provides an outdoor mountaineering foot-operated power generation device, comprising a fluid pad 1 and a base 13. The base 13 is provided with a power chamber 4, a bearing 7, and a reset chamber 11. The fluid pad 1 and the power chamber 4 are connected via a guide pipe 2. A linear gear 6, a large circular gear 8, a generator 9, and a small circular gear 10 are disposed between the power chamber 4 and the reset chamber 11. A coaxial small gear 14 is installed in the middle of the bearing 7. The two ends of the linear gear 6 are connected to the power chamber 4 and the reset chamber 11 respectively. The side of the linear gear 6 meshes with the coaxial small gear 14. The coaxial small gear 14 is coaxial with the large circular gear 8. The generator 9 is connected to the small circular gear 10, and the large circular gear 8 meshes with the small circular gear 10. The linear gear 6 transmits power to the coaxial small gear 14. The rotation of the coaxial small gear 14 drives the large circular gear 8. The large circular gear 8 contacts the small circular gear 10 above the generator 9, and the large circular gear 8 transmits power to the small circular gear 10. The small circular gear 10 drives the generator 9 to rotate and generate electricity.

[0024] Both the fluid pad 1 and the power chamber 4 have fluid inlets and outlets, and the inlets and outlets on the fluid pad 1 are connected by a guide pipe 2. The fluid pad 1 is filled with fluid, and the fluid inside the fluid pad 1 enters the power chamber 4 through the guide pipe 2.

[0025] The end of the power chamber 4 is provided with a power chamber fluid inlet 31 and a power chamber fluid outlet 32. The power chamber fluid inlet 31 and the power chamber fluid outlet 32 ​​are located at the two ends of the power chamber 4, respectively. The power chamber fluid inlet 31 has an internal thread hole structure and is connected to the guide pipe 2.

[0026] In this embodiment, the power chamber fluid inlet 31 and the power chamber fluid outlet 32 ​​constitute the power chamber fluid inlet and outlet 3. The guide pipe 2 is connected to the power chamber fluid inlet 31. Figure 6 The diagram shows the cross-sectional structure of the power chamber 4, and the fluid inlet 31 of the power chamber is an internally threaded hole structure.

[0027] The diameter of the sealing baffle 5 is the same as the inner diameter of the power chamber 4. The sealing baffle 5 has a sealing structure; the corresponding diagram in the attached figure is only a schematic diagram of the principle.

[0028] The linear gear 6 includes a linear gear body 61 and a linear gear connecting rod 62, which are fixedly connected in sequence. The linear gear body 61 has a flat cuboid structure with gear-shaped sides. The linear gear connecting rod 62 has a cylindrical structure, and a sealing baffle 5 is provided at the end of the linear gear connecting rod 62. The sealing baffle 5 has a disc-shaped structure. Figure 4 The diagram shown is a cross-sectional view of the linear gear 6.

[0029] The two sides of the spur gear body 61 are gear-shaped spur gears, which connect with the coaxial pinion 14 below the large circular gear 8. The position of the coaxial pinion 14 is as follows: Figure 3 As shown.

[0030] The gear-shaped part of the linear gear body 61 is a straight tooth, and the linear gear body 61 meshes with the coaxial small gear 14 below the large circular gear 8.

[0031] The large circular gear 8 and the coaxial small gear 14 are connected by a concentric shaft. The lower part of the concentric shaft is connected to a small bearing 7, which supports the two coaxial gears. In this embodiment, the structure formed by the large circular gear 8 and the coaxial small gear 14 is two in number and is symmetrically distributed on both sides of the linear gear 6, and is connected to two generators 9 respectively.

[0032] The reset cavity 11 is a cylindrical structure with an open end. A reset spring 12 is provided inside the reset cavity 11. The end of the reset spring 12 contacts the linear gear 6. The diameter of the reset spring 12 is smaller than the width of the linear gear 6.

[0033] The bottom of the reset cavity 11 is provided with a reset cavity support block 111. The top of the reset cavity support block 111 is fixedly connected to the reset cavity 11 as an integral structure, and the bottom of the reset cavity support block 111 is connected to the base 13.

[0034] In practical use, the linear gear 6 has a flat-headed end, but it can also be designed as a T-shaped structure to compress the return spring 12. The return spring 12 is placed inside the return cavity 11, and a cross-sectional view of the return cavity 11 is shown in the figure. Figure 5 As shown. The diameter of the reset spring 12 is smaller than the inner diameter of the reset cavity 11, and one end of the reset spring 12 contacts the bottom of the reset cavity 11. During the power generation process, the linear gear 6 compresses the reset spring 12, and the reset spring is in a compressed state; during the reset process, the reset spring 12 extends, pushing the sealing baffle 5 on the linear gear 6 to compress the fluid back to the fluid pad 1, and one power generation cycle is completed.

[0035] The working principle and process of this invention are as follows:

[0036] The fluid pad 1 has a fluid outlet, and the fluid pressure within the fluid pad 1 during walking is transmitted to the power chamber 4 through the guide pipe 2. The power chamber 4 contains a sealing baffle 5, which transmits the internal pressure to the linear gear 6. The sealing baffle 5 acts as a sealing piston, completely sealing the fluid within the power chamber 4 and the fluid pad 1. The outer diameter of the sealing baffle 5 is the same as the inner diameter of the power chamber 4. The sealing baffle 5 is directly connected to the linear gear 6, simultaneously transmitting power to the linear gear 6. The end of the linear gear 6 contacts the return spring 12, and the gear side of the linear gear 6 contacts the coaxial pinion 14 to transmit kinetic energy. The coaxial pinion 14 is concentric with the large circular gear 8, and its rotation drives the large circular gear 8 to rotate. A bearing 7 is located below the large circular gear 8 to ensure its normal rotation. The large circular gear 8 contacts the small circular gear 10 of the generator 9, and its rotation drives the small circular gear 10 to rotate. The linear gear 6 contacts the return spring 12. The diameter of the return spring 12 is smaller than the width of the linear gear 6 to ensure that the linear gear 6 can properly compress the return spring 12. The return spring 12 is placed inside the return cavity 11. The diameter of the return spring 12 is smaller than the inner diameter of the return cavity 11 to achieve normal compression and reset of the return spring 12.
