Description

Technical Field

[0001] This invention relates to the field of scooter technology, and more specifically to a folding scooter. Background Technology

[0002] Most folding mechanisms on the market today only consider ease of folding and simple operation. They do not take into account the potential for accidental activation of the folding mechanism during high-speed travel, which could lead to traffic accidents or safety hazards.

[0003] Existing scooters with anti-accidental activation devices typically only have one anti-folding lock, which is an overly simple mechanism. Alternatively, when folding, one hand must guide the folding while the other hand continuously grips the folding mechanism. This places high demands on the operator and is not effort-saving.

[0004] In existing scooter steering mechanisms, key components such as springs and nuts are exposed, making the structure unstable and prone to wear and tear.

[0005] In addition, when the scooter is large and heavy, conventional folding mechanisms are difficult to move when folded, and the tires are suspended in the air when folded, which is not conducive to towing the scooter.

[0006] Therefore, existing technologies still need to be improved and enhanced. Summary of the Invention

[0007] To address the problems existing in the background art, the present invention provides a folding scooter. The folding scooter of the present invention features stable folding and positioning, durability, controllable cost, and convenient operation.

When the main rod is folded, the hook is put into the sleeve for fixation.

[0011] The front wheel is connected to the pedal via the folding mechanism, and the front wheel remains on the ground when the main rod is folded. A side cover is provided on the side of the pedal to protect the internal battery and cover the side pivot, while also reducing wind resistance and extending range.

[0012] In the above technical solution, the side pivot includes a side pivot one and a side pivot two located on both sides of the pedal. The side pivot one and the side pivot two pass through the pedal and the bottom sides of the main rod and are connected to the folding mechanism.

[0013] Furthermore, the folding mechanism includes a folding connector, a folding unlocking mechanism, and a folding base;

[0014] The upper end of the folding connecting seat is connected to the riser, and the lower end is connected to the main rod; the folding connecting seat is connected to the folding base, and the folding base is connected to the front wheel, thereby realizing the steering of the front wheel through the riser; the folding unlocking mechanism cooperates with the folding base to realize the folding and unfolding of the main rod.

[0015] Furthermore, the structure of the folding connector specifically includes an upper inner connector, a lower inner connector, an upper outer connector, a lower outer connector, a bearing, and two connecting shafts;

[0016] The upper inner connector and the lower inner connector are connected; the upper outer connector and the lower outer connector are connected; the bearing is pressed against the inner side by the upper inner connector, the lower inner connector, the upper outer connector and the lower outer connector, thereby facilitating the rotation of the upper inner connector and the lower inner connector and reducing wear;

[0018] The lower inner connector has two symmetrically arranged vertically penetrating slots, and each slot has a limiting platform at its bottom. The two connecting shafts are located in the two slots of the lower inner connector. The connecting shafts are installed by inserting them into the slots from the top of the lower inner connector and being held in place by the limiting platform inside the lower inner connector. The tops of the two connecting shafts are equipped with springs, which exert downward pressure on the connecting shafts, thereby allowing the connecting shafts to move up and down within the slots of the lower inner connector. The connecting shafts cooperate with the folding base to control the direction of the front wheels.

[0019] The lower external connector is connected to the main rod.

[0020] Furthermore, the structure of the folding unlocking mechanism is as follows: the folding unlocking mechanism includes a folding hook, a folding pin, an upper slot, and a spring; the folding hook and the folding pin are connected, the upper slot is located at the bottom of the main rod, and the folding pin is installed in the upper slot; the spring is sleeved on the folding pin and located above the upper slot inside the main rod, and the spring is used to give the folding pin a downward force so that the bottom end of the folding pin is kept inside the folding base; the folding pin can be moved up and down by lifting and pressing the folding hook, the folding pin is located inside the folding base in the unfolded state, and the folding pin is located in the upper slot at the bottom of the main rod in the folded state.

[0021] Furthermore, the structure of the folding base specifically includes: a base, a connecting fitting, a connecting sleeve, a front wheel connecting fitting, a connecting pin, a folding guide seat, two steering bearings, and a slot;

[0022] The connecting fitting is provided on the surface of the base. There is a protrusion on the outer side of the connecting fitting. When the main rod is in the unfolded state, the protrusion is used to limit and retain the main rod.

[0023] The connecting fitting is connected to the connecting sleeve, and the connecting sleeve has a through circular hole, the size of which corresponds to the size of the connecting pin; the front wheel connector has a through track circular groove, and the connecting pin passes through the circular hole and the track circular groove to connect the connecting sleeve and the front wheel connector; two steering bearings are provided at the contact position between the connecting sleeve and the base.

[0024] The base is provided with an angle limiting groove at the installation position of the connecting pin to limit the steering angle of the front wheel. The angle limiting groove is composed of two symmetrical ° slots at the front and rear, and the steering range of the connecting pin is limited within the range of the slots.

[0025] The front wheel connector is connected to the connecting sleeve via a connecting pin, and the front wheel connector is connected to the front wheel to control the front wheel steering;

[0026] The connecting fitting has two grooves for engaging with the two connecting shafts of the folding connecting seat; when unfolded, the connecting shafts connect with the grooves, thereby enabling the riser to control the steering of the connecting fitting and thus the steering of the front wheels;

[0027] A copper sleeve is provided in the upper slot, and a copper sleeve is provided in the slot at the top of the base; the copper sleeves one and two are respectively interference-fitted with the upper slot and the slot to limit the axial displacement of the folding pin and maintain smoothness during displacement.

[0032] 2. The pedal side cover is easy and secure to install, and its streamlined design reduces wind resistance and extends the range of operation.

[0033] 3. The front wheels can absorb shocks and cushion the impact.

[0034] 4. The folding scooter of this invention has a main rod that is separated from the front wheel. When folded, the front wheel does not leave the ground, effectively protecting the scooter's bottom plate from friction with the ground and facilitating movement. The method of having both front and rear wheels on the ground is also suitable for moving heavier scooters in the folded state.

[0035] 5. In this invention, the main rod controls the rotation direction of the front wheel by setting two connecting shafts, so that the main rod is connected to the folding connecting seat, and the folding connecting seat is connected to the folding base. By cooperating with the connecting shaft and the folding base, the front wheel can be controlled by the riser. Compared with a single connecting shaft, this method has better stability.

[0036] 6. The folding mechanism, under the action of spring force, is less likely to be accidentally activated by the folding switch, thus achieving safety during driving in a simple way. Attached Figure Description

[0050] To make the present invention clearer, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0051] In such Figure 1 and Figure 2 In the embodiment shown, a folding scooter includes a riser 1, a main pole 2, a footboard 8, a folding mechanism 7, and front and rear wheels; the riser 1 is wrapped and fixed by the main pole 2.

[0052] The pedal 8 and the folding mechanism 7 are fixedly connected by side pivots 6 (including side pivot 6-a and side pivot 6-b located on both sides of the pedal 8). The side pivots 6 pass through the pedal 8 and the main rod 2 and are fixedly connected to the folding base 73. The main rod 2 can rotate around side pivot 6-a and side pivot 6-b. Through the above-mentioned connection relationship, the friction during the folding process can be reduced, thus reducing the resistance during folding.

[0053] A hook 11 is provided above the main rod 2, and a mudguard 12 is provided above the rear wheel at the bottom of the pedal 8. A sleeve is provided above the mudguard 12. When the main rod 2 is folded, the hook 11 is put into the sleeve for fixation.

[0054] from Figure 3 and Figure 4 As can be seen, the folding mechanism 7 includes: a folding connecting seat 71; a folding unlocking mechanism 72; and a folding base 73. The upper end of the folding connecting seat 71 is connected to the riser 1, and the lower end is connected to the main rod 2; the folding connecting seat 71 is connected to the folding base 73, and the folding base 73 is connected to the front wheel, thereby realizing the control of the front wheel steering through the riser 1; the folding unlocking mechanism 72 cooperates with the folding base 73 to realize the folding and unfolding of the main rod 2.

[0055] like Figure 5-7As shown, the folding connector 71 includes a bearing 715; two connecting shafts 716; an upper inner connector 711; a lower inner connector 712; an upper outer connector 713; and a lower outer connector 714.

[0056] The upper inner connector 711 and the lower inner connector 712 are connected by screws; the upper outer connector 713 and the lower outer connector 714 are also connected by screws. The bearing 715 is pressed inward by the upper inner connector 711, the lower inner connector 712, the upper outer connector 713, and the lower outer connector 714, which facilitates the rotation of the upper inner connector 711 and the lower inner connector 712 and reduces wear.

[0057] The riser 1 is fixedly connected to the upper inner connector 711 by two symmetrical screws, so that the upper inner connector 711 and the lower inner connector 712 can be rotated by rotating the riser 1.

[0058] like Figure 7 and 8 As shown, the lower inner connector 712 has two symmetrically arranged vertically penetrating slots, and each slot has a limiting platform 7121 at its bottom. The two connecting shafts 716 are located in the two slots of the lower inner connector 712. The connecting shafts 716 are installed by inserting them into the slots from the top of the lower inner connector 712 and being held in place by the limiting platform 7121 inside the lower inner connector 712. The tops of the two connecting shafts 716 are provided with springs, and the springs are connected to screws installed in the slots of the lower inner connector 712. The springs are used to generate downward pressure on the connecting shafts 716, thereby causing the connecting shafts 716 to move up and down within the slots of the lower inner connector 712. The connecting shafts 716 cooperate with the folding base 73 to control the direction of the front wheels.

[0059] The lower outer connector 714 in the folding connector 71 is connected to the main rod 2 by screws.

[0060] The folding unlocking mechanism 72 includes a folding hook 3, a folding pin 4, an upper slot 721, and a spring 9. The folding hook 3 and the folding pin 4 are connected by screws. The upper slot 721 is located at the bottom of the main rod 2. The folding pin 4 is installed in the upper slot 721. The spring 9 is sleeved on the folding pin 4 and is located above the upper slot 721 inside the main rod 2. By pressing the folding hook 3, the folding pin 4 can be moved up and down. In the unfolded state, the folding pin 4 is in the slot 739 of the folding base 73; in the folded state, the folding pin 4 is in the upper slot 721 at the bottom of the main rod 2. The spring 9 is used to apply a downward force to the folding pin 4, so that its bottom end is normally kept in the slot 739 of the folding base 73.

[0061] To reduce friction, a copper sleeve 10-a is provided in the upper slot 721 at the bottom of the main rod 2, and a copper sleeve 10-b is provided in the slot 739 at the top of the folding base 73. Copper sleeves 10-a and 10-b are interference-fitted with the upper slot 721 and slot 739, respectively. Copper sleeves 10-a and 10-b are used to limit the axial displacement of the folding pin 4 and to maintain smooth movement during displacement.

[0062] like Figure 9 and 10 As shown, the folding base 73 includes a base, a connecting fitting 733, a connecting sleeve 734, a front wheel connector 735, a connecting pin 736, a folding guide seat 731, two steering bearings 732, and a slot 739.

[0063] A protrusion 737 is provided on the outer side of the connecting and mating part 733 on the surface of the base. When the main rod 2 is in the extended state, the protrusion 737 is used to limit and retain the main rod 2.

[0064] The connecting fitting 733 and the connecting sleeve 734 are connected by screws. The connecting sleeve 734 has a through hole, the size of which corresponds to the size of the connecting pin 736. The front wheel connector 735 has a through racetrack-shaped circular slot, through which the connecting pin 736 passes to connect the connecting sleeve 734 and the front wheel connector 735. Two steering bearings 732 are located at the contact position between the connecting sleeve 734 and the base.

[0065] like Figure 11 As shown, an angle limiting groove 730 is provided on the base corresponding to the mounting position of the connecting pin 736. The angle limiting groove 730 consists of two symmetrical slots with angles of 90° to 150°, which limit the steering range of the connecting pin 736 within the range of the slots. This angle limiting groove 730 is used to limit the steering angle of the front wheels.

[0066] The front wheel connector 735 is equipped with a shock-absorbing spring. Under the action of the shock-absorbing spring, the front wheel connector 735 can move up and down within the range of the runway circular slot, and can achieve shock absorption and cushioning of the front wheel after being connected to the front wheel.

[0067] The front wheel connector 735 is connected to the connecting sleeve 734 via a connecting pin 736. The front wheel connector 735 is connected to the front wheel and controls the steering of the front wheel.

[0068] The connecting fitting 733 has two grooves 738 for engaging with the two connecting shafts 716 of the folding connecting seat 71. In the unfolded state, the connecting shafts 716 connect with the grooves 738, thereby enabling the riser 1 to control the steering of the connecting fitting 733 and thus control the steering of the front wheels.

[0069] Slot 739 is used to install copper sleeve 10-b and to house the folding pin 4. Copper sleeve 10-b is interference-fitted with slot 739.

[0070] The folding guide seat 731 is located next to the slot 739. Its surface is arc-shaped along the folding path. It is used to hold the folding pin 4 when the scooter is unfolded and serves as a guide.

[0071] Folding process: Lifting the folding hook 3 moves the folding pin 4 upward, overcoming the spring force of the spring 9 and disengaging it from the slot 739. This method allows for easy and convenient folding and unlocking. At this time, the main rod 2 can be folded. When the main rod 2 is folded backward, the folding pin 4 will abut against the arc surface of the folding guide seat 731, guiding the vehicle body to rotate around the side pivot 6-a and the side pivot 6-b. The folding guide seat 731 ensures stable and reliable folding.

[0072] When the hook 11 is rotated to contact the mudguard 12, the hook 11 is locked in the sleeve on the mudguard, thus achieving self-locking.

[0073] Deployment process: Disconnect hook 11 from mudguard, lift main rod 2 forward, and folding pin 4 will fall into slot 739 under the action of spring 9, completing the deployment and locking. If the connecting shaft 716 on main rod 2 is not connected to the groove 738 on folding base 73 at this time, the connecting shaft 716 will be pressed back into the lower inner connecting member 712 by connecting fitting 733. At this time, the riser 1 cannot control the front wheel steering. Simply use your foot to straighten the front wheel, and the connecting shaft 716 will be locked into the groove 738 on folding base 73 under the action of spring, so that the riser 1 can drive the front wheel to rotate, and the deployment is fully realized.

[0074] The inner side of the pedal 8 is provided with a mounting platform 81 for the side pivot 6, and the side pivot 6 is fixed to the mounting platform 81 of the pedal 8 by mounting screws 811.

[0075] To achieve an overall aesthetically pleasing and streamlined design, reduce wind resistance, extend battery life, protect the internal battery, and cover the side pivot 6, the side of the pedal 8 is provided with a pedal side cover 83.

[0076] like Figure 12 The installation method for the pedal side cover 83 shown is as follows: a special screw 821 is threadedly connected to the mounting hole 82 on the inner side of the pedal 8. For example... Figure 13 As shown, the surface of the special screw 821 has a groove 822. The buckle 823 on the pedal side cover 83, which corresponds to the mounting hole 82, passes through the special screw 821 and engages with the groove 822, thus completing the installation of the pedal side cover 83. This achieves a stable connection, making installation convenient and simple, and greatly improving installation efficiency.

[0077] Inside the pedal side cover 83, the battery is encased in a battery box. The battery box has two screw holes that connect to the screw slots inside the pedal 8 for easy and simple installation.

[0078] Finally, a foot pad can be added to the pedal of the present invention to enhance foot comfort and make it more aesthetically pleasing.
