Description

Technical Field

[0001] This invention relates to the field of electric walking device technology, specifically an electric walking device with adjustable and foldable shape. Background Technology

[0002] Currently, people use a wide variety of transportation tools. The advent of various transportation tools, such as bicycles, has brought a lot of convenience to mankind. However, although these transportation tools are easy to use, they are inconvenient to carry, especially when traveling. Transportation tools are only needed in certain specific locations, and most of the time they are not needed. These inconvenient transportation tools become a burden. Therefore, the development of portable transportation tools has always been a public need. For example, the folding electric bicycles that have emerged in recent years have alleviated the problem of inconvenience to some extent. However, the folded bicycles are still relatively large and inconvenient for users to carry. Their portability is still not good. To address this, we propose an electric walking device with adjustable and foldable shape. Summary of the Invention

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: This adjustable and foldable electric walking device has the following advantages:

[0015] 1. By installing a pneumatic telescopic rod, the user can adjust the height of the saddle by toggling a switch located on the underside of the saddle. This switch, via a pipeline, controls the air valve on the pneumatic telescopic rod, causing it to extend and retract. Once adjusted, the user can sit on the saddle, where the two armrests provide safety. Movement is then achieved by rotating the two motor wheels using the operating handle.

[0016] 2. When the user needs to stand in a semi-standing position, adjust the height of the saddle and the length of the telescopic lever to adjust the height of the two handrails. After adjustment, place both feet on the upper side of the front pedal and then control the two motor wheels to rotate via the operating handle to achieve semi-standing mobility. This adjusts the user's posture, making it convenient and effortless.

[0017] 3. By setting up interlocking and locking buckles, when carrying is needed, the two motor frames can be flipped to the left around the connecting bracket to align with the lower sides of the two longitudinal tube supports, and the two traction wheels can be brought to contact the ground. Then, the saddle frame is rotated downwards around the pivot, causing the saddle to contact the left longitudinal tube. After contact, the two folding handles are pulled to move the two threaded rods and separate them from the two hinged frames. After separation, the support frame can be bent to extend the telescopic rod. Then, the telescopic rod is flipped to align with the right side of the longitudinal tube. Then, the four longitudinal tubes are rotated counterclockwise around the connection point of the concave and convex tube ends to align with the upper sides of the two longitudinal tube supports. After alignment, folding is completed. After folding, it can be moved by pulling the telescopic rod, making it very convenient to carry. Attached Figure Description

[0035] Among them: a wheel frame is installed on the right side of the motor frame 3, an anti-tilt wheel 18 is rotatably connected to the lower side of the wheel frame, and a trolley wheel 19 is installed on the upper side of the wheel frame. The trolley wheel 19 makes it convenient for users to drag the vehicle after folding it.

[0036] The telescopic rod 11 is equipped with a power supply box 44. The input end of the operating handle 10 is electrically connected to the output end of the power supply box 44, and the output end of the operating handle 10 is electrically connected to the input ends of the two motor wheels 25 respectively.

[0037] The working principle of the adjustable and foldable electric walking device provided by this invention is as follows: In use, the power supply box is installed on the telescopic rod 11. The operating handle 10 and motor wheels 25 are electrically connected to the power supply. The wiring is routed through a conduit to avoid obstruction during the folding process. Then, its output end is connected to the input end of the operating handle 10. After connection, the output end of the operating handle 10 is connected to the input ends of the two motor wheels 25 respectively. During use, the user can toggle the toggle switch 37 on the underside of the saddle 27 according to their needs. In this case, the toggle switch 37 controls the air valve of the pneumatic telescopic rod 5 through the conduit, thereby controlling the extension and retraction of the pneumatic telescopic rod 5. During the extension and retraction of the pneumatic telescopic rod 5, the height of the saddle 27 can be adjusted. The user can sit on the saddle 27 with both feet placed on the upper side of the front pedal 1. At this time, the two armrests 9 will protect the user. After adjustment, turning the two adjustment knobs 15 causes the two flexible shafts 14 to rotate, which in turn rotates the two threaded rods 42. During the rotation of the threaded rods 42, the distance between them and the top rod 17 can be adjusted. When adjusted to the appropriate position, pressing the armrest 9 causes the threaded rods 42 to move back and contact the top rod 17, forming a certain angle between the top rod 17 and the armrest 9. After contact, the angle of the armrest 9 is adjusted. Then, the two motor wheels 25 can be rotated by operating the handle 10 to move the user. When the user needs to stand semi-standing, adjust the saddle 27 to an appropriate height and simultaneously adjust the length of the telescopic pull rod 11 to adjust the distance between the two armrests. Adjusting the height of pedal 9, the user places both feet on the upper side of the front pedal 1, with their buttocks still against the saddle 27, forming a semi-standing posture. Then, by controlling the two motor wheels 25 with the operating handle 10, the user can stand and walk comfortably and effortlessly. When carrying the device, rotate the operating handle 10 and the left and right armrests 9 clockwise 90 degrees upwards to align with the telescopic lever 11. After aligning the operating handle 10, left and right armrests 9, and telescopic lever 11, pry open the lever folding buckle 8. The telescopic lever 11 can then rotate downwards 180 degrees. Then, pull up the saddle opening 7 to separate the lower end of the axle hook 39 from the retaining pin 35. After separation, rotate the saddle frame 6 downwards around the pivot 36, causing the saddle 27 to fold downwards and contact the left longitudinal tube. Then, engage the two locking buckles 12... Separate the two flaps 26, then separate the hoof-shaped clip 22 from the load-bearing tube 23, and rotate the four longitudinal tubes 4 counterclockwise by 90 degrees around the connection between the tube head concave 20 and the tube head convex 21 to fit against the upper side of the two longitudinal tube supports 2. Then rotate the two motor frames 3 clockwise around the connecting bracket 28 to move to the left and fit against the lower side of the two longitudinal tube supports 2, so that the two traction wheels 19 are in contact with the ground downwards. This completes the folding. After folding, rotate the two locking frames 45 to make them perpendicular to the longitudinal tube supports 2, and then lock the four folded longitudinal tubes 4 into the interior of the front and rear locking frames 45 respectively. After locking, the stability during carrying can be ensured. Then, it can be moved by pulling the telescopic rod 11, which is very convenient for carrying.
