Description

Technical Field

[0001] The invention relates to a scooter structure, in particular to a dual-purpose electric scooter which has the dual functions of electric drive and foot drive and can change the width of the pedal according to the use requirements. Background Art

[0002] There are some disadvantages in the use of general electric scooters, which limit their safety and practicality. First, electric scooters only have two wheels, front and rear. When users slide at a high speed, they are prone to tipping and falling due to unstable center of gravity. This design limits the user's balance ability, which is especially dangerous for beginners, the elderly or people who are not familiar with scooters.

[0003] Secondly, the width of the pedals of general electric scooters is usually too small, and users can only stand with their feet tilted forward and backward, which also affects the user's balance. Standing on the narrow pedals for a long time may cause foot discomfort or even foot pain. This uncomfortable experience limits people's comfort and durability on the scooter.

[0004] In addition, electric scooters can only be driven by electricity, and cannot be used when the battery is dead. This means that when users need to use the scooter for a long time, they must always pay attention to the power level to avoid running out of power during the journey and being unable to move forward. This limitation of relying on electricity makes electric scooters obviously less practical, especially when traveling long distances or in places without power, users will not be able to rely on electric scooters as their main means of transportation.

[0005] In summary, general electric scooters have obvious shortcomings in terms of safety, comfort and practicality. In order to improve the user experience of electric scooters, the present invention pays more attention to the balance and safety of users in design and provides a more comfortable pedal space, which will make electric scooters more popular and meet people's needs for convenient, environmentally friendly and safe travel.

[0081] In order to further understand and appreciate the purpose, features and effects of the present invention, please refer to the following (simple illustration with diagrams) for detailed description:

[0082] See also Figures 1 to 7A dual-purpose electric scooter includes: a battery box 10, an electric wheel 20, a control handle 30, two pedals 40, two telescopic rods 50 and a pedal controller 60, an electric wheel 20 is pivotally mounted on a bogie 22 with a wheel seat 21, and the wheel seat 21 is formed with a first rotating ring 23, and a male gear ring 231 is formed on one side of the first rotating ring 23, and the electric wheel 20 is fixed to the front end of the battery box 10 with the bogie 22, and the electric wheel 20 is connected to the battery box 10 to form an electrical connection, that is, the battery box 10 can supply power to the electric wheel 20 to form a power source. A control handle 30 is provided with a second hand grip 31 at one end, and the hand grip 31 is provided with at least one driving controller 32. The other end of the control handle 30 is connected to the wheel seat 21 of the electric wheel 20, and the driving controller 32 is electrically connected to the electric wheel 20 to form control, and the control includes instructions such as start, acceleration, deceleration, and shutdown. The control handle 30 can also drive the electric wheel 20 to swing and turn. The control handle 30 is penetrated by an outer tube 33, and the outer tube 33 is formed with a second rotating ring 34, and a female gear ring 341 is formed on one side of the second rotating ring 34, and a spring 35 is sandwiched between the first rotating ring 23 and the second rotating ring 34. A fixing bolt 36 is passed through the first rotating ring 23 and the second rotating ring 34, and a grip button 37 is screwed on the fixing bolt 36. When the grip button 37 is locked, the male gear ring 231 and the female gear ring 341 are meshed with each other. When the grip button 37 is loosened, the elastic force of the spring 35 separates the male gear ring 231 and the female gear ring 341 from each other. The battery box 10 is recessed with a receiving groove 11, and the receiving groove 11 runs through the front and rear ends of the battery box 10. The outer tube 33 can be rotatably received in the receiving groove 11 at the first rotating ring 23, thereby reducing the storage volume. The control handle 30 can be further received and used as a general skateboard. The two pedals 40 are relatively fixed with a first slide rail rod 41 and a second slide rail rod 42, and the first slide rail rod 41 and the second slide rail rod 42 slide against each other to form the separation and combination displacement of the two pedals 40, and the two pedals 40 are slidably arranged at the middle section of the battery box 10 by the first slide rail rod 41 and the second slide rail rod 42, and the other two pedals 40 are both provided with a rear wheel 43 at a position relatively far away from the electric wheel 20. Further, the first slide rail rod 41 is provided with a limit strip 411 on one side, and the second slide rail rod 41 is provided with a limit strip 412 on one side. A limiting groove 421 is recessed on one side of the rod 42, and the first slide rail rod 41 and the second slide rail rod 42 are slidably arranged with each other through the limiting strip 411 and the limiting groove 421, and the first slide rail rod 41 and the second slide rail rod 42 are both protruding on the other side with a side strip 412 (422), and the side strip 412 (422) is limited at the battery box 10, thereby limiting the two pedals 40 from sliding in parallel, and forming a load-bearing support for the pedal 40 through the first slide rail rod 41 and the second slide rail rod 42.Two telescopic rods 50 are symmetrically arranged on both sides of the battery box 10, and one end of the telescopic rod 50 is pivoted on the battery box 10, and the other end of the telescopic rod 50 is pivoted on the pedal 40. A tension spring 51 is installed inside the two telescopic rods 50, and the tension spring 51 pushes against the two ends of the telescopic rod 50 to provide tension. A pedal controller 60 is fixed to the rear end of the battery box 10, and the pedal controller 60 is connected to a connecting component 70, and the connecting component 70 connects the two pedals 40 to form a drive, that is, it can control the two pedals 40 to separate and approach each other.

[0083] For the actual operation, please refer to Figure 1 , 5, 7, 8, the battery box 10 is provided with a battery and a control circuit, because it is not the focus of the present invention, so it is not further marked in the figure. The front end of the battery box 10 is pivotally provided with the electric wheel 20 by the bogie 22, and the electric power supplied by the battery box 10 drives the electric wheel 20 to roll forward, and the electric wheel 20 is sequentially connected to the wheel seat 21, the outer tube 33, and the control handle 30 upward, and the control handle 30 can be extended and lowered relative to the outer tube 33, and the first rotating ring 23 and the second rotating ring 34 form a stepless angle adjustment of the control handle 30, that is, it can adjust the appropriate position to suit users of different heights, so that the user can comfortably hold the grip 31 with both hands, and operate the drive controller 32 to form the acceleration and deceleration control of the electric wheel 20. Among them, the two pedals 40 are slidably arranged above the battery box 10 by the first slide rod 41 and the second slide rod 42 respectively, and are provided for the user to step on with both feet. The two pedals 40 are both equipped with the rear wheels 43, that is, the two rear wheels 43 can cooperate with the electric wheel 20 to form a triangular stable arrangement. Furthermore, two telescopic rods 50 are connected between the two pedals 40 and the battery box 10, thereby improving the stability of the two pedals 40 at any position, that is, the swing gap between the two pedals 40 can be eliminated, thereby reducing the shaking of the user stepping on the pedals 40. Furthermore, the pedal controller 60 includes a stepping motor 61, and the connecting component 70 includes a shaft 71 and a bidirectional screw 72. One end of the shaft 71 is connected to the stepping motor 61, and the other end of the shaft 71 is provided with a worm 711. A worm gear 721 is sleeved at the middle section of the bidirectional screw 72, and the worm gear 721 engages with the worm 711. The two pedals 40 are symmetrically provided with a connecting block 44, and the two ends of the bidirectional screw 72 are passed through the connecting block 44, so that the bidirectional screw 72 engages with the internal thread of the connecting block 44, and the axial rotation of the bidirectional screw 72 drives the connecting block 44 and the pedal 40 to form a displacement. When the two pedals 40 are close together, the two pedals 40 form a shape that is large enough for the user to stand with both feet together, especially to stand with both toes facing forward. This is the most stable and comfortable way to stand and is suitable for slower electric drive modes. The power can also be turned off to slide with one foot on the ground. That is, the two pedals 40 in a close relationship do not affect the sliding action of one foot on the ground. On the other hand, the two pedals 40 can be tightly close together to cover the receiving groove 11, thereby preventing foreign objects from falling into the receiving groove 11. To further explain, when sliding with one foot on the ground, the electric wheel 20 can be driven to roll, and the electric wheel 20 can be used to charge the battery box 10 using the generator principle. It can also be used for long descents and braking to achieve the purpose of reverse charging. For another actual use action, please refer to Figure 4 , 6As shown in Figures 7 and 9, when high-speed electric driving is required, the stepper motor 61 of the pedal controller 60 is controlled, and the stepper motor 61 drives the shaft 71 of the connecting assembly 70 to rotate along the axis. At this time, the worm 711 of the shaft 71 is engaged to drive the worm gear 721, so that the bidirectional screw 72 rotates to push the linkage blocks 44 of the two pedals 40, so that the two pedals 40 move symmetrically to the two outer sides of the battery box 10, thereby forming a larger spacing between the pedals 40, so that the user can stand on the two pedals 40 with feet as wide as shoulders, and at the same time, the relative distance between the two rear wheels 43 is increased, that is, a more stable use state can be provided, which is more suitable for high-speed electric driving. In summary, the scooter has the dual functions of electric drive and foot drive at the same time, and cooperates with the stepless spacing adjustment of the two pedals 40, so that the user can adjust the pedal 40 to a comfortable and safe position according to needs and body shape, so as to provide a scooter structure with both practicality and safety.

[0084] Another practical function of the present invention is to refer to Fig.10 , 11 As shown in Figures 12, the control handle 30 is provided with a connecting block 38 on the outer sides of the two gripping parts 31, and the connecting block 38 is tubular and has a blocking member 381 which can be telescopically penetrated at both ends. When the control handle 30 is folded into the receiving groove 11 of the battery box 10, the control handle 30 will be aligned with or slightly lower than the stepping plane of the pedal 40, and the blocking member 381 will be higher than the stepping plane of the pedal 40, so that a box or an object can be stably placed on the pedal 40, and The blocking member 381 blocks one end of the box or the article, that is, blocks the rear end of the battery box 10. On the other hand, the battery box 10 is equipped with a pull rod 12 at the front end. The user can hold the pull rod 12 to suspend the electric wheel 20 in the air, and push and pull the two rear wheels 43 against the ground to accommodate the scooter or cargo. When the scooter is to be stored, the blocking member 381 can be extended so that the blocking member 381 can support the scooter against the ground, so that it has the function of standing storage.

[0085] The present invention provides another use state, see Figure 1 , 2As shown in Figure 13, the pedal controller 60 includes a stepping motor 61, and the connecting assembly 70 includes a shaft 71 and a bidirectional screw 72. One end of the shaft 71 is connected to the stepping motor 61, and the other end of the shaft 71 is provided with a conical threaded portion 712, and a bevel gear 722 is sleeved at the middle section of the bidirectional screw 72, and the conical threaded portion 712 is meshed by the bevel gear 722. The two pedals 40 are symmetrically provided with a linkage block 44, and the two ends of the bidirectional screw 72 are penetrated by the linkage block 44, so that the bidirectional screw 72 is meshed with the internal thread of the linkage block 44, and the bidirectional screw 72 is meshed with the internal thread of the linkage block 44, and the linkage block is driven by the axial rotation of the bidirectional screw 72. 44 and the pedal 40 form displacement. When the user operates the stepper motor 61 to rotate, the shaft 71, the conical threaded portion 712, the bevel gear 722 and the bidirectional screw 72 can be driven in sequence. The bidirectional screw 72 pushes the linkage block 44 in both directions, so that the two pedals 40 slide along the first slide rail 41 and the second slide rail 42, so that the two pedals 40 form a stepless adjustment action of mutual folding and unfolding. Therefore, it has the dual functions of electric drive and foot drive, and cooperates with the stepless spacing adjustment of the two pedals 40, so that the user can adjust the pedal 40 to a comfortable and safe position according to needs and body shape, so as to provide a scooter structure with both practicality and safety.

[0086] The present invention provides another embodiment. Figure 6 , 14As shown in FIGS. 15 , the pedal controller 60 includes a knob 62, and the connecting assembly 70 includes a cable reel 73 and two rotating wheel seats 74. The knob 62 is connected to the cable reel 73 to form a manual operation. The cable reel 73 is wound with at least one pull rope 731, and the pull rope 731 is respectively extended and connected to the two rear wheels 43. The two rotating wheel seats 74 are fixed to the two sides of the battery box 10 and face the rear wheels 43, and the pull rope 731 is wound around the rotating wheel seats 74. The battery box 10 is symmetrically provided with two spring push rods 75, and the two spring push rods 75 are respectively pushed on the two rear wheels 43. The pedal controller 60 further includes a ratchet gear 63, at least one position-limiting ratchet 64 and a control ring 65. The ratchet gear 63 is connected between the knob 62 and the wire reel 73, and the position-limiting ratchet 64 is disposed on the outer edge of the ratchet gear 63 to form a one-way meshing. The control ring 65 is disposed on the outer edges of the ratchet gear 63 and the position-limiting ratchet 64, and the control ring 65 can press the position-limiting ratchet 64 to disengage it from the ratchet gear 63. When the two pedals 40 need to be moved, the position-limiting ratchet 64 can be moved. When adjusting the position, the knob 62 is held by hand and rotated clockwise, driving the ratchet gear 63 and the reel 73 to rotate synchronously, the reel 73 pulls the pull rope 731 to reel in, and then the pull rope 731 pulls back the rear wheel 43, so that the two pedals 40 can be close to each other to slide along the first slide rail 41 and the second slide rail 42. On the other hand, the pedal controller 60 can only rotate the knob 62 in the clockwise direction through the one-way engagement of the ratchet gear 63 and the limit ratchet 64. The two pedals 40 can be adjusted by rotating the control ring 65 and the control ring 65 can be used to press the limit ratchet 64 to separate the ratchet gear 63. When the ratchet gear 63 is not blocked by the limit ratchet 64, the knob 62, the ratchet gear 63 and the reel 73 can all rotate in the reverse direction. The two spring push rods 75 push the telescopic rod 50 to form an extension thrust, and then the two pedals 40 are automatically pushed outward to the unfolded position without being restricted by the pedal controller 60. The two pedals 40 have the dual functions of electric drive and foot drive, and the stepless spacing adjustment of the two pedals 40 allows the user to adjust the pedals 40 to a comfortable and safe position according to needs and body shape, so as to provide a scooter structure with both practicality and safety.
