Description

Technical Field

[0001] This invention belongs to the fields of transportation vehicles and human-assisted walking equipment, specifically relating to a human-assisted scooter that uses stationary stepping and cycling. Background Technology

[0002] Scooters, as a common short-distance transportation tool, promote green travel due to their simple structure, ease of use, and low-carbon environmental friendliness. Scooters are widely popular among teenagers, serving not only as entertainment but also as a means of transportation or exercise, making them a very popular type of outdoor recreational and sports equipment.

[0003] Currently, most scooters sold and used by consumers are designed for children. Although their structures vary, their user base is limited. Existing scooters are mostly for entertainment purposes, and there is a lack of suitable products for adults, especially the elderly with limited mobility, who urgently need assistive devices. Existing scooters rely on pushing off the ground or twisting the body to glide, resulting in weak driving force. Most existing scooters use two-wheel or three-wheel support, which leads to poor stability and a tendency to tilt or even tip over. Existing scooters have limited steering angles, making it difficult to adjust the angle precisely and prone to veering off course. Existing scooters also place a significant burden on the body's metabolism, making them unsuitable for sustained long-distance use and unable to meet daily commuting needs. Summary of the Invention

[0022] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0023] Example 1 This invention relates to a human-assisted stationary pedaling scooter, such as... Figure 1 As shown, the system includes a frame module 2, which is connected to an upwardly extending handlebar module 6. A steering module 5 is connected to the bottom of the frame module 2 near the handlebar module 6. A pedal module 1 is also movably connected to the frame module 2. The bottom of the pedal module 1 is connected to a gear steering module 3 via a rope drive module 4. The gear steering module 3 is rotatably connected to the frame module 2 via a shaft. In this embodiment, the pedal module 1, gear steering module 3, rope drive module 4, steering module 5, and handlebar module 6 are assembled into a complete structure using the frame module 2. When the pedal module 1 is pressed, it moves the rope drive module 4, which in turn drives the gear steering module 3 to rotate, thus moving the frame module 2. The steering module 5 can change the direction of movement of the overall structure, and the handlebar module 6 provides support for the user and assists in controlling the steering module 5 to change direction.

[0024] Example 2 like Figure 2As shown, in this embodiment, the pedal module 1 includes a left pedal 1-12 and a right pedal 1-17 symmetrical about the centerline of the frame module 2. The forefoot portion of the right pedal 1-17 is fixedly connected to the pivot of a right pulley 1-1. It also includes a grooved pulley plate A1-2, which is fixedly connected to the frame module 2. Each right pulley 1-1 slides back and forth in the groove of the pulley plate A1-2. A fixing member A1-16 is fixedly connected to the bottom rear end of the right pedal 1-17. The fixing member A1-16 is perpendicularly connected to the shaft A1-15. A hollow shaft A1-3 is fixedly sleeved at the end of the shaft A1-15. The hollow shaft A1-3 is fixedly connected to a crank A1-5 perpendicular to the corresponding shaft A1-15. The bottom of the left pedal 1-12 has a dovetail groove, and a slider A1-10 is slidably connected within the dovetail groove of the left pedal 1-12. The bottom of block A1-10 is connected to gear steering module 3; the front part of the left pedal 1-12 is fixedly connected to the shaft of a left pulley 1-4, and also includes a grooved pulley plate B1-9. The pulley plate B1-9 is fixedly connected to the frame module 2, and each left pulley 1-4 slides back and forth in the groove of the pulley plate B1-9; the bottom of the rear end of the left pedal 1-12 is also fixedly connected to a fixing member B1-8. A shaft B1-7 passes through the fixing member B1-8. A hollow shaft B1-6 is fixedly sleeved at the end of the shaft B1-7. The hollow shaft B1-6 is fixedly connected to a crank B1-13 perpendicular to the corresponding shaft B1-7. The ends of crank A1-5 and crank B1-13 are both vertically connected to a connecting shaft 1-14. The connecting shaft 1-14 is rotatably connected to the frame module 2. The bottom of the fixing member A1-16 is fixedly connected to a rope transmission module 4.

[0025] In this embodiment, the transmission route of the pedal module 1 is as follows: The right pedal 1-17 and the left pedal 1-12 are arranged symmetrically along the central axis. Specifically, the forefoot portion of the right pedal 1-17 is fixedly connected to the pivot of the right pulley 1-1. The right pulley 1-1 slides back and forth in the groove of the pulley plate A1-2. The rear end of the right pedal 1-17 is fixedly connected to the fixing member A1-16. The shaft A1-15 passes through the fixing member A1-16, allowing the right pedal 1-17 to rotate around the shaft A1-15 at the right heel. The hollow shaft A1-3 is coaxially connected to the fixed shaft A1-15 and is fixedly connected to the crank A1-5. The crank A1-5 rotates around the connecting shaft 1-14.

[0026] Similarly, the left pedal 1-12 and right pedal 1-17 are connected in the same way, with the left and right sides of the connecting shaft 1-14 differing by 180 degrees. The forefoot portion of the left pedal 1-12 is fixedly connected to the pivot of the left pulley 1-4, which slides back and forth in the groove of the pulley plate B1-9. The rear end of the left pedal 1-12 is fixedly connected to the fixing piece B1-8, and the shaft B1-7 passes through the fixing piece B1-8, allowing the left pedal 1-12 to rotate around the shaft B1-7 at the left heel. The hollow shaft B1-6 is coaxially connected to the shaft B1-7, and the shaft B1-7 is fixedly connected to the crank B1-13. The crank B1-13 rotates around the connecting shaft 1-14.

[0027] It also includes a pin 1-11, which securely connects the left pedal 1-12 and the slider A1-10. The bottom of the left pedal 1-12 has a dovetail groove. When the slider A1-10 slides into the bottom of the left pedal 1-12, the pin 1-11 secures the left pedal 1-12 to the slider A1-10. The slider A1-10 has a rectangular through hole along its length, allowing the small shaft 3-14 to reciprocate. The small shaft 3-14 passes through pre-drilled holes at both ends of the U-shaped slider 3-13, forming a hinge structure with the connecting rod a3-7. The upper end of the connecting rod a3-7 rotates around the small shaft 3-14, and the lower end of the connecting rod a3-7 rotates with the thick shaft 3-5. The thick shaft 3-5 passes through the hole at the smallest angle of the reversing triangle 3-12. Thus, the left pedal 1-12 and the reversing triangle 3-12 are connected.

[0028] Example 3 like Figure 3 As shown, the frame module 2 includes an integral frame 2-4. A crank support 2-6 is fixedly connected to the integral frame 2-4. The crank support 2-6 is rotatably connected to a connecting shaft 1-14. A circular hole is formed on the crank support 2-6, through which a support rotation shaft 2-5 is connected. Multiple support frames 2-1 are fixedly connected to the integral frame 2-4. The support frames 2-1 are connected to the support rotation shaft 2-5 via bearings. A gear steering module 3 and a rope drive module 4 are fixedly connected to the support rotation shaft 2-5. The rear end of the integral frame 2-4 is open... The outer ring of the one-way bearing 2-10 is connected via a connecting sleeve. The inner ring of the one-way bearing 2-10 is fixedly connected to the hollow rotating shaft 2-9. The inner ring of the rotating shaft 2-9 is connected to the rotating shaft a2-7 via key a2-8. The rotating shaft 2-9 is connected to the transmission gear 2-3 via spline 2-11. The transmission gear 2-3 is meshed with the gear steering module 3. A rotating wheel 2-2 is connected to each end of the rotating shaft a2-7. The front end of the overall frame 2-4 is connected to the steering module 5 and the handlebar module 6. A front wheel 2-12 is connected to each end of the rotating shaft a2-7.

[0029] The transmission route of frame module 2 is as follows: The outer ring of the rotating shaft 2-9 is connected to the one-way bearing 2-10, and the inner ring is fixed to the rotating shaft a2-7 via key a2-8. The rotating shaft a2-7 is connected to the rotating wheel 2-2 to transmit torque.

[0030] In the pre-drilled holes at the front end of the overall frame 2-4, the right-side fixing pin 5-17 and the left-side fixing pin 5-1 are connected to the right-side steering linkage 5-15 and the left-side steering linkage 5-5 respectively, thus forming a connection between the frame module 2 and the steering module 5.

[0031] Example 4 like Figure 4 As shown, the gear steering module 3 includes a sprocket 3-1 connected to the supporting rotating shaft 2-5 via key b3-2. The supporting rotating shaft 2-5 is connected to gear a3-6 near its end via key c3-15. The end of the supporting rotating shaft 2-5 is connected to the middle of the reversing triangle plate 3-12 via a bearing. The three corners of the reversing triangle plate 3-12 are respectively rotatably connected to the fixed shaft a3-10, the fixed shaft b3-11, and the coarse shaft 3-5. The fixed shaft a3-10 is rotatably connected to gear b3-8 via one-way bearing a3-9. The fixed shaft b3-11 is rotatably connected to gear c3-3 via one-way bearing b3-4. Gear c3-3 meshes with gear a3-6 and gear b3-8. Gear b3-8 meshes with transmission gear 2-3. The coarse shaft 3-5 passes through the bottom end of the connecting rod a3-7. The top end of the connecting rod a3-7 is connected to the slider A1-10 via a hinge device. The sprocket 3-1 meshes with the rope transmission module 4.

[0032] The hinge device includes a U-shaped slider 3-13, with the top end of the connecting rod a3-7 inserted into the U-shaped slider 3-13, and also includes a small shaft 3-14, which passes through the connecting rod a3-7 and the U-shaped slider 3-13 to fix and connect to slider A1-10.

[0033] The transmission route of gear steering module 3 is as follows: like Figure 4 As shown, the small shaft 3-14 passes through the holes reserved at both ends of the U-shaped slider 3-13, forming a hinge structure with the connecting rod a3-7. The upper end of the connecting rod a3-7 rotates around the small shaft 3-14, and the lower end of the connecting rod a3-7 rotates with the thick shaft 3-5. The thick shaft 3-5 passes through the hole of the smallest angle of the reversing triangle 3-12, so that the reversing triangle 3-12 can rotate around the supporting rotation axis 2-5.

[0034] One-way bearings a3-9 and b3-4 are installed in the largest pre-drilled hole in the middle of the reversing triangle 3-12, passing through the supporting rotating shaft 2-5. Simultaneously, a fixed shaft b3-11 passes through the right-angle hole in the reversing triangle 3-12, and a fixed shaft a3-10 passes through the hole with the smallest angle. Sprockets 3-1 are connected to the supporting rotating shaft 2-5 via key b3-2, and gear a3-6 is connected to the supporting rotating shaft 2-5 via key c3-15. Gear a3-6 meshes with gear c3-3, and gear c3-3 meshes with gear b3-8. Gears a3-6, c3-3, and b3-8 are installed in the reversing triangle 3-12, forming the gear reversing module C. By changing the angle of the reversing triangle 3-12, transmission gear 2-3 can mesh with both gear c3-3 and gear b3-8.

[0035] Gear c3-3 is connected to fixed shaft b3-11 via one-way bearing b3-4, and gear b3-8 is connected to fixed shaft a3-10 via one-way bearing a3-9. Transmission gear 2-3 is fixedly connected to rotating shaft 2-9 via spline 2-11. The inner ring of rotating shaft 2-9 is connected to rotating shaft a2-7 via key a2-8. Rotating shaft 2-7 is connected to rotating wheel 2-2 to transmit torque. This establishes a connection between gear reversing module C and frame module B.

[0036] Example 5 like Figure 5 As shown, the rope drive module 4 includes a rope A4-2, one end of which is connected to a fixing member A1-16. The rope A4-2 passes through a pulley assembly and connects to one end of a chain 4-1. The other end of the chain 4-1 is connected to the left pedal 1-12 via a rope B. The chain 4-1 is engaged with a sprocket 3-1.

[0037] The pulley assembly includes a right vertical fixed pulley 4-5 fixedly sleeved on the supporting rotating shaft 2-5, and also includes a fixed shaft c4-7 and a fixed shaft d4-3 fixedly connected to the overall frame 2-4. A right horizontal fixed pulley 4-6 is sleeved on the fixed shaft c4-7, and a left horizontal fixed pulley 4-4 is sleeved on the fixed shaft d4-3. Rope A4-2 passes through the right vertical fixed pulley 4-5, the right horizontal fixed pulley 4-6, and the left horizontal fixed pulley 4-4 in sequence and then connects to the chain 4-1.

[0038] The transmission route of the rope drive module 4 is as follows: like Figure 5 As shown, one end of rope A4-2 is connected to the fixing member A1-16, passes through the right vertical fixed pulley 4-5 and the right horizontal fixed pulley 4-6 respectively, and then passes over the left horizontal fixed pulley 4-4. The other end of rope A4-2 is connected to the chain 4-1.

[0039] The right vertical fixed pulley 4-5 is installed on the supporting rotating shaft 2-5, the right horizontal fixed pulley 4-6 is installed on the fixed shaft c4-7, and the left horizontal fixed pulley 4-4 is installed on the fixed shaft d4-3.

[0040] One end of rope A4-2 is fixedly connected to the fixing part A1-16, and the other end is connected to the left pedal 1-12 through chain 4-1 and rope B, so that the rope transmission module 4 is connected to the pedal module 1. The sprocket 3-1 cooperates with the chain 4-1 for transmission, and the sprocket 3-1 and gear a3-6 are coaxially driven, all of which are installed on the support rotating shaft 2-5.

[0041] Example 6 like Figure 6 As shown, the steering module 5 includes a right steering link 5-7 and a left steering link 5-5, which are connected to the overall frame 2-4 at one end via a right fixing pin 5-2 and a left fixing pin 5-1. The other end of the left steering link 5-5 is connected to one end of the link b5-6 via a rotating shaft b5-3. Similarly, in the left-right symmetrical structure, one end of the right steering link 5-7 is connected to one end of the link c5-8 via a rotating shaft c5-4. It also includes a T-shaped rod 5-9. The two ends of the T-shaped rod 5-9 are connected to the other ends of the link b5-6 and the link c5-8 via rotating shafts e5-10 and f5-11, respectively. The third end of the T-shaped rod 5-9 is rotatably connected to the bottom of the handlebar module 6.

[0042] The transmission route of steering module 5 is as follows: Reference Figure 6 One end of the left steering link 5-5 rotates around the left fixing pin 5-1, and the other end of the left steering link 5-5 rotates around the rotation axis b5-3. Similarly, in the left-right symmetrical structure, one end of the right steering link 5-7 rotates around the right fixing pin 5-2, and the other end of the right steering link 5-7 rotates around the rotation axis c5-4.

[0043] One end of connecting rod b5-6 rotates around rotation axis b5-3, and the other end of connecting rod b5-6 rotates around rotation axis e5-10. Similarly, in the left-right symmetrical structure, one end of connecting rod c5-8 rotates around rotation axis f5-11.

[0044] One end of the T-shaped rod 5-9 rotates around the hollow shaft e6-4 to transmit the handlebar steering torque. The other end of the T-shaped rod 5-9 is connected to the connecting rod b5-6 and the connecting rod c5-8 respectively. Thus, the handlebar steering module 5 and the frame module 2 are connected.

[0045] Example 7 like Figure 7As shown, the handlebar module 6 includes an integral handlebar 6-1. The upper end of the hollow shaft c6-10 is connected to the middle of the integral handlebar 6-1. The lower end of the hollow shaft c6-10 is threaded to the top of the rotating shaft d6-8. The rotating shaft d6-8 is sleeved with the hollow shaft d6-2. The bottom of the rotating shaft d6-8 is connected to the top of the hollow shaft e6-4 through the fixing pin 6-3. The hollow shaft e6-4 is sleeved with the hollow shaft f6-5. The hollow shaft f6-5 is connected to the folding device 6-6. The hollow shaft d6-2 is sleeved with the hollow device 6-9 and the buckle 6-7. The hollow shaft e6-4 passes through the third end of the T-shaped rod 5-9 and is connected to the front end of the integral frame 2-4.

[0046] The transmission route of handlebar module 6 is as follows: like Figure 7 As shown, the integral handlebar 6-1 is fixedly connected to the hollow shaft c6-10. The top of the hollow shaft e6-4 is connected to the rotating shaft d6-8 via a fixing pin 6-3. The outside of the hollow shaft e6-4 is connected to the hollow shaft f6-5. The outside of the hollow shaft f6-5 is fixedly connected to the folding device 6-6. The top of the rotating shaft d6-8 is coaxially connected to the hollow shaft d6-2, forming a threaded connection with the lower end of the hollow shaft c6-10. The outside of the hollow shaft d6-2 is fixedly connected to the telescopic device 6-9 and the buckle 6-7.

[0047] The handlebars can be folded around the fixing pin 6-3, the integral handlebar 6-1, and the hollow shafts c6-10 and d6-2.

[0048] The working principle of the human-powered stationary stepping scooter of this invention is as follows: When a person steps down with their left foot, the rear side of the left pedal 1-12 will move downward, and the front side of the left pedal 1-12 will move upward.

[0049] When the rear side of the left pedal 1-12 moves downward, the fixing part B1-8 connected to the rear side of the left pedal 1-12 will drive the crank B1-13 to rotate clockwise through the shaft B1-7 and the hollow shaft B1-6, while the left pulley 1-4 moves backward.

[0050] At the same time, crank B1-13 drives crank A1-5 to rotate clockwise through connecting shaft 1-14. Crank A1-5 drives chain 4-1 and rope A4-2 to start transmission through fixed hollow shaft A1-3 and shaft A1-15.

[0051] At the same time, the right pulley 1-1 moves forward, while the rear side of the right pedal 1-17 moves upward and the front side of the right pedal 1-17 moves downward.

[0052] The U-shaped slider 3-13 moves forward, driving the reversing triangle 3-12 to rotate counterclockwise via the thick shaft 3-5. This causes the reversing triangle 3-12 to drive the entire reversing gear set to rotate counterclockwise, enabling the five gears to drive in sequence. The sprocket 3-1 rotates coaxially with gear a3-6, gear a3-6 meshes with gear c3-3, gear c3-3 simultaneously meshes with gear b3-8, and gear b3-8 meshes with transmission gear 2-3.

[0053] Specifically, the gear transmission involves chain 4-1 driving sprocket 3-1 to rotate clockwise. Sprocket 3-1, through key b3-2, key c3-15, and supporting rotating shaft 2-5, drives gear a3-6 to rotate clockwise. Gear a3-6 meshes with gear c3-3, driving gear c3-3 to rotate counterclockwise. Gear c3-3 meshes with gear b3-8, driving gear b3-8 to rotate clockwise. Gear b3-8 meshes with transmission gear 2-3, driving transmission gear 2-3 to rotate counterclockwise. Gear d3-5, through a key and shaft, provides assistance for the counterclockwise rotation of the wheel.

[0054] When a person steps down with their right foot, the rear side of the right pedal 1-17 will move downward, and the front side of the right pedal 1-17 will move upward.

[0055] When the rear side of the right pedal 1-17 moves downward, the fixing part A1-16 connected to the rear side of the right pedal 1-17 will drive the crank A1-5 to rotate clockwise through the shaft A1-15 and the hollow shaft A1-3, while the right pulley 1-1 moves backward.

[0056] Crank A1-5 drives crank B1-13 to rotate clockwise via connecting shaft 1-14. Crank B1-13 is connected to fixing piece B1-8 via hollow shaft B1-6 and shaft B1-7, which drives chain 4-1 and rope A4-2 to start transmission.

[0057] The left pulley 1-4 moves forward, while the rear side of the left pedal 1-12 moves upward and the front side of the left pedal 1-12 moves downward.

[0058] At the same time, the hinge U-shaped slider 3-13 moves backward, driving the reversing triangle plate 3-12 to rotate clockwise through the thick shaft 3-5, thereby causing the reversing triangle plate 3-12 to drive the entire gear set to rotate clockwise, so that the four gears can be driven at the same time.

[0059] In this state, the gear transmission specifically involves chain 4-1 driving sprocket 3-1 to rotate counterclockwise. Sprocket 3-1, through key b3-2, key c3-15, and support shaft 2-5, drives gear a3-6 to rotate counterclockwise. Gear a3-6 meshes with gear c3-3, driving gear c3-3 to rotate clockwise. Gear c3-3 meshes with transmission gear 2-3, driving transmission gear 2-3 to rotate counterclockwise. Transmission gear 2-3 provides assistance for the counterclockwise rotation of the wheel.
