DETAILED DESCRIPTION

[0023] This disclosure is further explained in combination with drawings and embodiments.

[0024] Referring to FIGS. 1 to 5, this disclosure provides a high-energy power generation device for casual shoes, which comprises a worm, an upper cover 2 and a lower cover 3 which can be buckled together, as well as a battery 4, a motor 5, a forward transmission crown gear 10, a transmission gear set, a backward transmission crown gear 16 and a planetary gear set which are disposed between the upper cover 2 and the lower cover 3.

[0025] The upper end of the worm extends out of the surface of the upper cover 2. The high-energy power generation device further comprises a pedal 1 disposed above the worm. The worm is meshed with a through hole in the center of the forward transmission crown gear 10. The planetary gear set nests the periphery of the forward transmission crown gear 10 and is meshed with the periphery of the forward transmission crown gear 10. The backward transmission crown gear 16 nests the periphery of the forward transmission crown gear 10, is disposed above the planetary gear set and is meshed with a gear in the planetary gear set. The backward transmission crown gear 16 is meshed with a gear in the transmission gear set. The gear in the transmission gear set is meshed with the gear of the motor 5, and the motor 5 is connected to the battery 4.

[0026] It should be noted that a circuit board is further disposed between the motor 5 and the battery 4. The electrical energy generated by the motor 5 firstly flows into the circuit board and is then transmitted to be stored in the battery 4 after flowing into the circuit board. The electric energy stored in the battery 4 can be configured to charge an external electrical appliance (for example, a mobile phone). Charging of the battery may be performed using a universal interface or wirelessly.

[0027] Further, the worm is a dual-tooth worm 7. Threads of the dual-tooth worm 7 are meshed with a through hole in the center of the forward transmission crown gear 10. A linear bearing 8 is arranged below each of two support pillars of the dual-tooth worm 7 respectively. A compression spring 9 sleeves the periphery of the linear spring 8. The high-energy power generation device further comprises a spring cover disposed on the bottom of the forward transmission crown gear 10. The bottoms of the two compression springs 9 are disposed on the spring cover respectively. The high-energy power generation device further comprises a backward positioning clip and an extension spring 17. One end of the backward positioning clip is fixed on the spring cover by the extension spring 17, and the other end of the backward positioning clip is clamped on meshing teeth on the outer surface of the planetary outer gear.

[0028] The planetary gear set nests the periphery of the forward transmission crown gear 10. The planetary gear set comprises a planetary outer gear 12, three forward positioning clips 18 and three planetary gears 19. The planetary outer gear 12 nests the periphery of the forward transmission crown gear 10. The forward positioning clips 18 and the planetary gears are disposed on the planetary outer gear 12 alternately. One ends of the forward positioning clips 18 are fixed on the planetary outer gear 12, and the other ends thereof clamp the meshing teeth on the side surface of the forward transmission crown gear 10. The planetary gears 19 are conical teeth. One surfaces of the planetary gears 19 are meshed with meshing teeth on the bottom of the forward transmission crown gear 10 at the bottom, while the other surfaces of the planetary gears are meshed with the meshing teeth on the bottom of the backward transmission crown gear 16. The backward transmission crown gear 16 nests the periphery of the forward transmission crown gear 10, is disposed above the planetary gear set and is meshed with the gear in the planetary gear set. The backward transmission crown gear 16 is meshed with the gear in the transmission gear set.

[0029] The transmission gear set comprises a first transmission gear 14 and a second transmission gear 15. The backward transmission crown gear 16 is meshed with the first transmission gear 14. The first transmission gear 14 is meshed with the second transmission gear 15. The second transmission gear 15 is meshed with an output shaft of the motor 5.

[0030] The high-energy power generation device further comprises two thrust bearings 11. One of the two thrust bearings 11 is disposed above the backward transmission crown gear 16 on the periphery of the worm 7, while the other of the two thrust bearings is disposed below the forward transmission crown gear 10.

[0031] A working principle of this disclosure is as follows.

[0032] When the pedal 1 is pedaled down, the dual-tooth worm 7 moves downwards. Since the dual-tooth worm 7 is meshed with the forward transmission crown gear, the forward transmission crown gear is driven to rotate; at this point, the three forward positioning clips 18 in the planetary gear set stop the planetary outer gear 12 from moving, and the planetary outer gear 12 is allowed to only rotate along with the forward transmission crown gear 10. Due to the characteristics of the planetary gear 19, at this point, the backward transmission crown gear on the upper part can only synchronously rotate in the same direction along with the forward transmission crown gear 10. The backward transmission crown gear transmits power to the next transmission tooth, thereby finishing a transmission process of downward pedaling.

[0033] At this point, the meshing between the dual-tooth worm 7 and the forward transmission crown gear 10 is disengaged, and the forward transmission crown gear 10 continues rotating due to inertia. When the feet are lifted up, the pedal 1 and the dual-tooth worm 7 are lifted upwards due to a counteraction force of the compression springs 9. The dual-tooth gear 7 is meshed with the forward transmission crown gear 10 again; the forward transmission crown gear 10 starts to rotate backwards. Meanwhile, the three forward positioning clips 18 lose effects due to backward rotation; at this point, the planetary outer gear 12 is fixed by the backward positioning clip and cannot rotate, and the integral planetary gears 19 start the transmission to drive the backward transmission crown gear on the upper part. At this point, the backward transmission crown gear is unchanged in transmission direction, so that the transmission from the pedaling down and lifting up of the teeth without direction change is finished. Finally, the meshing between the worm and the forward transmission crown gear 10 is disengaged, and the forward transmission crown gear 10 is allowed to continuously move due to inertia.

[0034] Referring to FIG. 6, as an embodiment, this disclosure may be placed in the heel 20 of a shoe 20, such that the pedal 1 is fully fitted with the heel. When the pedal 1 and the compression springs 9 drive the dual-tooth worm 7 to move vertically, the forward transmission crown gear 10 is then driven to rotate, so as to drive the gear in the planetary gear set to rotate. The backward transmission crown gear 16 is caused to rotate, and then the backward transmission crown gear 16 causes the power generator 5 to generate power by the transmission gear set.

[0035] In conclusion, this disclosure provides an efficient high-energy power generation device with a concise structure and an exquisite design. By the transmission design of the forward transmission crown gear, the transmission gear set, the backward transmission crown gear and the planetary gear set, this disclosure can generate power when the feet are pedaled down or lifted up, and power generation efficiency is doubled totally.

[0036] Only preferable embodiments of this disclosure are provided in the preceding text and are not intended to limit this disclosure. Any modification, equivalent replacement and improvement made within the spirit and principle of this disclosure shall be included within the protection scope of this disclosure.
