Technical Field

[0001] This invention relates to the field of electric scooter technology, and particularly to a highly stable folding electric scooter. Background Technology

[0002] An electric scooter is a personal transportation device powered by electricity, typically consisting of an electric motor, battery pack, and controller. It combines the design of a traditional scooter with the power system of an electric vehicle, providing a convenient and fast way to commute in the city. Electric scooters offer significant advantages for urban commuting and short-distance travel: convenience, environmental friendliness, economy, health benefits, and entertainment. Overall, as a modern urban transportation tool, the electric scooter combines convenience, environmental friendliness, and economy, and is gradually becoming an important part of people's daily lives. Existing electric scooters generally have a folding function, meaning the pole at the front of the scooter can be folded for easy carrying. However, existing folding methods are cumbersome, requiring tedious disassembly and making subsequent maintenance inconvenient. Therefore, this invention proposes an electric scooter with a convenient folding operation, facilitating subsequent maintenance and simplifying operation. Summary of the Invention

Detailed Implementation

[0024] Example: Figures 1 to 8 As shown, a lower hinge seat 4 is rotatably mounted on the front end of the base 1, and a vertical tube 6 is detachably mounted on the lower hinge seat 4; an upper hinge seat 5 is mounted on the bottom end of the vertical tube 6, and the upper hinge seat 5 and the lower hinge seat 4 are connected by a pin; a front wheel 3 is mounted on the bottom end of the lower hinge seat 4, and a rear wheel 2 is mounted on the rear end of the base 1 for movement.

[0025] An adjustment mechanism is provided on the lower hinge seat 4. The adjustment mechanism includes push rods 9 arranged in an array on the lower hinge seat 4 to support the bottom of the upper hinge seat 5. The adjustment mechanism includes a protective cover 8 provided on the side of the lower hinge seat 4. An adjustment gear 13 is rotatably installed inside the protective cover 8. An adjustment bolt 12 is provided on the end face of the adjustment gear 13. The adjustment mechanism also includes an adjustment gear ring 11 rotatably installed on the lower hinge seat 4. The adjustment gear ring 11 and the adjustment gear 13 form a gear pair. A gear 10 meshes on the outside of the adjustment gear ring 11. The gear 10 is rotatably installed on the lower hinge seat 4, and the gear 10 and the push rods 9 form a helical pair. The push rods 9 are provided with threads 901, and the bottom end of the push rods 9 is provided with a sliding shaft 902. The sliding shaft 902 is telescopically installed on the lower hinge seat 4. The threads 901 and the gear 10 form a helical pair.

[0026] Fixing mechanisms are provided on both sides of the lower hinge seat 4 to fix the insert shaft. The fixing mechanism includes mounting cylinders 17 on both sides of the lower hinge seat 4, and a fixing seat 21 is slidably provided on the inner side of the mounting cylinder 17. The fixing seat 21 cooperates with the insert shaft to fix the insert shaft. The insert shaft includes an insert shaft body 7, and release balls 14 are arranged in an array on the circumference of the insert shaft body 7. The release balls 14 have oil holes. An oil pipe 703 is provided inside the insert shaft body 7, and the oil pipe 703 is connected to each release ball 14. Oil is introduced into the oil pipe 703 and the oil is transferred to the release balls 14. Fixing grooves 701 are provided at both ends of the insert shaft body 7. The fixing grooves 701 cooperate with the fixing seat 21 to fix the shaft. The fixing mechanism includes a mounting cylinder 17 rotatably mounted on the outside of the mounting cylinder 17. The actuating ring 18 has a pressure roller 20 on its inner circumference, which pushes the fixed seat 21. The fixed seat 21 has an inclined surface facing the pressure roller 20, which contacts the pressure roller 20. A spring 19 is connected between the fixed seat 21 and the inner side of the mounting cylinder 17 to provide elastic force. A spring 16 is connected between the actuating ring 18 and the side of the lower hinge seat 4 to provide elastic force. The actuating rings 18 on both sides of the lower hinge seat 4 are connected by a connecting shaft 15 to rotate synchronously. A fixing screw 22 is threaded on the outer circumference of the actuating ring 18. The fixing screw 22 is threaded on the side of the lower hinge seat 4 to fix the actuating ring 18. The insert shaft includes a cap 702 threaded on one end of the insert shaft body 7 to seal the oil pipe 703.

[0027] The principle of this invention is as follows: the riser 6 and the base 1 can be folded and completely disassembled; specifically, when folding, the front insert shaft is removed to fold the riser 6; when disassembling, the two insert shafts are removed to remove the riser 6.

[0028] The insert shaft fits between the upper hinge seat 5 and the lower hinge seat 4 to fix the riser 6. Specifically, when installing the insert shaft, the fixing groove 701 on the insert shaft body 7 fits with the fixing seat 21 to complete the fixation. That is, by turning the actuating ring 18, the actuating ring 18 rotates, and the pressure roller 20 pushes the inclined surface of the fixing seat 21, causing the fixing seat 21 to slide radially. The fixing seat 21 fits with the fixing groove 701, thus completing the fixation. Furthermore, the fixing screw 22 is fixed to the side of the lower hinge seat 4 by threaded connection to fix the actuating ring 18 to ensure stability.

[0029] During routine maintenance, i.e. when adding lubricating oil, the cover 702 can be removed to directly introduce oil into the shaft body 7. The oil is then transmitted through the oil pipe 703 to the release balls 14 at various locations and released through the oil holes on the release balls 14, thus adding oil to the lubrication area.

[0030] Furthermore, by adjusting the adjusting bolt 12, the adjusting gear 13 can be rotated. Under the gear transmission, the adjusting gear ring 11 rotates, and then the gear 10 rotates, causing the push rod 9 to move. Adjusting the height of the push rod 9 provides support for the upper hinge seat 5 at different heights. In other words, adjusting the height of the push rod 9 adjusts the height of the upper hinge seat 5, so that the insertion shaft will not vibrate due to dimensional tolerances after insertion.
