Description

Technical Field

[0001] This utility model belongs to the field of scooter technology, specifically relating to a foldable electric scooter. Background Technology

[0002] Electric scooters are vehicles based on traditional human-powered skateboards, with the addition of an electric motor. Electric scooters are generally divided into two-wheel drive or single-wheel drive, with the most common transmission methods being hub motors and belt drive, and their main power source being lithium battery packs.

[0003] Currently, electric scooters often require riders to stand on top of the platform during use, which can easily lead to rider fatigue and poses certain safety hazards over time. To optimize the performance of electric scooters, existing models are equipped with seats, which riders can sit on while riding. These seats are usually foldable. However, even when folded, the seats on existing electric scooters remain above the footboard, occupying footboard space and preventing riders from standing on the footboard to use the scooter. Utility Model Content

[0004] This utility model provides a foldable electric scooter, which aims to solve the problem in the prior art that the seat of the electric scooter is still above the footboard after being folded, occupying the footboard space and making it impossible for the rider to stand on the footboard to use the electric scooter.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A foldable electric scooter includes a frame on which a rear wheel assembly is mounted, and a seat assembly is also mounted on the frame.

[0007] The seat assembly is mounted on the vehicle frame via a folding mechanism. The seat assembly includes a used state and a folded state. When the folding mechanism is operated to put the seat assembly in the folded state, the seat assembly is folded above the rear wheel assembly. When the folding mechanism is operated to put the seat assembly in the used state, the seat assembly is located above the vehicle frame.

[0008] A further improved solution: the seat assembly is rotatably connected to the vehicle frame via a rotating frame, and the folding mechanism is disposed between the rotating frame and the vehicle frame.

[0009] Based on the above technical solution, a rotating frame is installed between the seat assembly and the vehicle frame. This rotating frame, serving as the rotational connection point for the seat assembly, not only enhances the stability of the seat during folding and unfolding but also allows the seat to maintain stable support at different angles. This design not only improves seat comfort but also further enhances the structural stability and safety of the entire vehicle.

[0010] A further improved solution: The folding mechanism includes a fixed seat fixed to the rotating frame and a sliding seat slidably connected to the vehicle frame. The fixed seat is provided with a limit block, and the sliding seat is provided with a protrusion that contacts the limit block. When the sliding seat is operated so that the limit block aligns with the protrusion, the folding mechanism locks the seat assembly in the use state. When the sliding seat is operated so that the limit block and the protrusion are misaligned, the folding mechanism folds the seat assembly to the folded state.

[0011] Based on the above technical solution: the locking structure of the limiting block and the protrusion ensures the stability of the seat during use, providing users with a comfortable riding experience. The sliding seat design allows users to easily lock and fold the seat without additional tools or complicated steps. The close cooperation between the various components of the folding mechanism makes the overall structure more compact, reducing unnecessary space occupation and improving the vehicle's portability. During the seat folding process, the folding mechanism ensures that the seat assembly folds smoothly and safely above the rear wheel assembly, avoiding safety hazards caused by improper operation.

[0012] A further improved solution: The frame is provided with a sliding column, the sliding seat is slidably connected to the sliding column, the cross-sectional shape of the sliding column is polygonal, and the sliding seat is provided with a sliding hole that mates with the sliding column.

[0013] Based on the above technical solution: the cross-sectional shape of the polygonal slide column allows the sliding seat to maintain a stable movement trajectory during sliding, avoiding the wobbling problem caused by a circular slide column. This design not only improves the stability of the seat assembly during folding and locking, but also extends the service life of the slide seat and slide column. The geometry of the polygonal slide column allows the slide seat to automatically position itself when it slides to a specific location, without the need for additional adjustments or calibrations. This design simplifies the folding and locking operation of the seat assembly, improving the user experience. The tight fit between the polygonal slide column and the sliding hole reduces the friction area during sliding, thereby reducing wear. This design not only improves the durability of the slide seat and slide column, but also reduces noise and vibration caused by wear.

[0014] A further improved solution: There are two protrusions, which are symmetrically arranged on the sliding seat; there are two limiting blocks, which are symmetrically arranged on the fixed seat.

[0015] Based on the above technical solution: the symmetrical arrangement of the two protrusions and two limiting blocks provides the folding mechanism with stronger stability in the locked state. When the sliding seat slides to the position opposite to the fixed seat, the two protrusions simultaneously contact and lock with the two limiting blocks, forming a stable locking structure. This design effectively prevents the seat from loosening or shifting due to uneven force on a single protrusion or limiting block. The symmetrical design simplifies the operation of the folding mechanism. The user simply slides the sliding seat along the slide column to the position opposite to the fixed seat, and the two protrusions automatically align and lock with the two limiting blocks. This design requires no additional adjustment or calibration steps, making operation faster and more accurate. Because the protrusions and limiting blocks are symmetrically designed, they are subjected to more even force in the folding mechanism. This design effectively reduces wear and damage caused by uneven force, thereby extending the service life of the folding mechanism.

[0016] A further improved solution: The sliding seat is also provided with a handle for pressing the sliding seat, and the sliding seat and the frame push the sliding seat to make the protrusion correspond to the limiting block.

[0017] Based on the above technical solution: the handle design allows users to more easily push the sliding seat without directly touching it, thus avoiding discomfort caused by hand friction with the sliding seat. Furthermore, the shape and size of the handle are carefully designed to ensure users can comfortably and accurately grip and push the sliding seat. By pushing the sliding seat with the handle, users can more accurately control the sliding seat's movement distance and speed, ensuring that the protrusion and the limiting block accurately align and engage. This design effectively prevents seat loosening or displacement due to improper operation. With the assistance of the elastic element, the folding mechanism has stronger stability in the locked state. When the protrusion and the limiting block are engaged, the elastic element provides a certain pressure, ensuring the seat assembly is firmly fixed to the frame.

[0018] A further improved solution: the fixed base is cylindrical, the sliding base is located inside the fixed base, the rotating frame is provided with a through hole, the handle extends out of the rotating frame through the through hole, and the handle is located on the side of the rotating frame away from the vehicle frame.

[0019] Based on the above technical solution: the cylindrical fixed seat can tightly wrap around the sliding seat, reducing unnecessary space occupation and making the folding mechanism more compact and aesthetically pleasing. The tight fit between the fixed seat and the sliding seat ensures the stability of the folding mechanism in the locked state. When the sliding seat slides along the fixed seat to the position corresponding to the limit block, the fixed seat provides solid support, preventing the seat assembly from shaking or shifting due to uneven force.

[0020] A further improved solution: The frame is also provided with a handlebar assembly, which is rotatably connected to the frame. A locking mechanism is provided between the handlebar assembly and the frame to lock the handlebar assembly. The handlebar assembly includes a stowed state and an extended state. The handlebar assembly can be switched between the extended state and the stowed state by operating the locking mechanism.

[0021] Based on the above technical solution, the locking mechanism design ensures that the handlebar assembly is securely fixed to the frame in the unfolded state, preventing it from loosening or shifting due to bumps or collisions. This design effectively improves vehicle safety during riding. The locking mechanism is simple and straightforward to operate; users can easily fold and unfold the handlebar assembly. This design not only saves users time but also enhances the user experience.

[0022] A further improved solution: The locking mechanism includes a locking groove disposed on the frame, a slider disposed on the handlebar assembly that cooperates with the locking groove, an operating part for operating the slider to move the slider, and a guide groove disposed on the handlebar assembly that cooperates with the slider. When the slider is operated to cooperate with the locking groove, the handlebar assembly is in an unfolded state. When the slider is operated to disengage from the locking groove, the handlebar assembly is in a retracted state.

[0023] Based on the above technical solution: the locking groove and the slider are the core components of the locking mechanism. The locking groove is positioned appropriately on the frame to ensure a tight fit with the slider. The slider is mounted on the handlebar assembly, corresponding one-to-one with the locking groove. When the slider is fully embedded in the locking groove, the handlebar assembly is securely fixed to the frame, forming a stable support structure. The operating part is the key component for user control of the slider's movement. This design places the operating part in an easily accessible location on the handlebar assembly for convenient user operation. The guide groove ensures the stability and accuracy of the slider during movement. The shape of the guide groove matches the slider, guiding it along a predetermined trajectory. This design not only improves the smoothness of slider movement but also avoids locking mechanism failure caused by slider misalignment.

[0024] A further improvement: The handlebar assembly is also equipped with a front wheel assembly.

[0025] Based on the above technical solution, the direct connection between the front wheel assembly and the handlebar assembly allows the rider to control the direction and steering angle of the front wheel more directly through the handlebars, thereby improving the vehicle's handling and responsiveness. As a crucial component of the electric scooter, the design of the front wheel assembly's position significantly impacts the vehicle's stability. Placing the front wheel assembly on the handlebar assembly helps lower the vehicle's center of gravity, enhancing stability during riding, especially when turning or encountering uneven surfaces. Space utilization is a critical consideration in the design of foldable electric scooters. Placing the front wheel assembly on the handlebar assembly allows for more efficient use of space, making the folded scooter more compact and easier to carry and store. The integrated design of the front wheel assembly and handlebar assembly also makes front wheel maintenance more convenient. The rider can more easily access the front wheel for inspection, tire replacement, or other necessary maintenance.

[0026] The beneficial effects of this utility model are as follows:

[0027] In this design, the seat folds up above the rear wheels, completely freeing up the footboard space. The rider can then freely stand on the footboard to control the electric scooter without worrying about the seat obstructing their movement. This design significantly improves space utilization, ensuring the electric scooter maintains high flexibility and convenience in various usage scenarios. The rider can flexibly choose between standing or riding modes based on their needs. Standing mode is suitable for rapid movement or intense maneuvering; the seat can be easily unfolded for rest or long-distance riding. This versatility greatly enhances the user experience and satisfaction.

[0028] With the seat folded above the rear wheels, the electric scooter becomes more compact, making it easier to carry and store. This is undoubtedly a huge convenience for users who frequently need to bring their electric scooters into public transportation or confined spaces. By cleverly designing the seat folding mechanism above the rear wheels, this invention not only solves the space occupation problem but also makes the overall design of the vehicle simpler and more aesthetically pleasing. This design concept provides new inspiration and direction for the future development of electric scooters. With the increasing popularity of electric scooters and intensifying market competition, user demands for the product are becoming more diversified. This invention, by solving the space occupation problem after the seat is folded, meets users' needs for portability, flexibility, and versatility, thus gaining stronger competitiveness in the market.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model. All other embodiments obtained by users of the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0040] refer to Figures 1 to 7 A foldable electric scooter includes a frame 1, a rear wheel assembly 2 mounted on the frame 1, and a seat assembly 3 mounted on the frame 1.

[0041] The seat assembly 3 is mounted on the frame 1 via a folding mechanism 4. The seat assembly 3 has a used state and a folded state. When the folding mechanism 4 is operated to put the seat assembly in the folded state, the seat assembly 3 is folded above the rear wheel assembly 2. When the folding mechanism 4 is operated to put the seat assembly 3 in the used state, the seat assembly 3 is located above the frame 1.

[0042] Wherein: the seat assembly 3 is rotatably connected to the vehicle frame 1 via a rotating frame 5, and the folding mechanism 4 is disposed between the rotating frame 5 and the vehicle frame 1. The rotating frame 5 may have an arc-shaped portion, and after the seat assembly 3 is folded, the curved portion surrounds the upper half of the rear wheel assembly 2 to further reduce the space occupied by the seat assembly 3.

[0043] Specifically: The folding mechanism 4 includes a fixed seat 6 fixed to the rotating frame 5 and a sliding seat 7 slidably connected to the frame 1. The fixed seat 6 is provided with a limiting block 61, and the sliding seat 7 is provided with a protrusion 71 that contacts the limiting block 61. When the limiting block 61 aligns with the protrusion 71 by operating the sliding seat 7, the folding mechanism 4 locks the seat assembly 3 into the use state. When the limiting block 61 and the protrusion 71 are displaced by operating the sliding seat 7, the folding mechanism 4 folds the seat assembly 3 into the folded state.

[0044] Wherein: a sliding column 8 is provided on the frame 1, and a sliding seat 7 is slidably connected to the sliding column 8. The sliding column 8 has a polygonal cross-sectional shape, and the sliding seat 7 has a sliding hole that mates with the sliding column 8. There are two protrusions 71, which are symmetrically arranged on the sliding seat 7. There are also two limiting blocks 61, which are symmetrically arranged on the fixing seat 6.

[0045] Specifically: The sliding seat 7 is also provided with a handle 9 for pressing the sliding seat 7. An elastic element, which pushes the sliding seat 7 against the frame 1, causes the protrusion 71 to correspond with the limiting block 61. The elastic element can be a spring, used to push the sliding seat 7 into the fixed seat 6 to lock the rotating frame 5, preventing accidental movement of the sliding seat 7. When accidental movement of the sliding seat 7 is less likely, the elastic element may not be provided. The handle 9 is rotatably connected to the sliding seat 7.

[0046] Wherein: the fixed base 6 is cylindrical, the sliding base 7 is located inside the fixed base 6, the rotating frame 5 is provided with a through hole, and the handle 9 extends out of the rotating frame 5 through the through hole, and the handle 9 is located on the side of the rotating frame 5 away from the frame 1. The handle 9 can be fixed to the sliding base 7 with screws. Alternatively, the handle 9 can also be an integral structure with the sliding base 7.

[0047] The frame 1 is equipped with a handlebar assembly 10, which is rotatably connected to the frame 1. A locking mechanism 11 is provided between the handlebar assembly 10 and the frame 1 to lock the handlebar assembly 10. The handlebar assembly 10 has a retracted state and an extended state. By operating the locking mechanism 11, the handlebar assembly 10 can switch between the extended and retracted states. The locking mechanism 11 includes a locking groove on the frame 1. The handlebar assembly 10 has a slider that engages with the locking groove. The handlebar assembly 10 also has an operating part that moves the slider. The handlebar assembly 10 also has a guide groove that engages with the slider. When the slider engages with the locking groove, the handlebar assembly 10 is in the extended state. When the slider disengages from the locking groove, the handlebar assembly 10 is in the retracted state. A front wheel assembly 12 is also provided on the handlebar assembly 10.

[0048] The working principle of this embodiment:

[0049] After the folding mechanism 4 is unlocked, gently lift the seat assembly 3 upwards to gradually unfold it from the folded state. During the unfolding process, be careful to maintain the balance of the seat assembly 3 to avoid suddenly letting go and causing the seat to fall. Once the seat assembly 3 is fully unfolded, secure it to the designated position on the frame 1. In this state, the rider can then ride the electric scooter.

[0050] When the seat needs to be folded, the folding mechanism 4 gently presses down on the seat assembly 3, causing it to gradually fold over the rear wheels. During the folding process, care should be taken to maintain the balance and stability of the seat assembly 3 to avoid collisions with the frame 1 or other components. After the seat assembly 3 is folded, the driver can drive the electric sliding board while standing.

[0051] This utility model is not limited to the above-mentioned optional embodiments. Under the premise of non-contradiction, the various solutions can be combined arbitrarily. Anyone can derive other forms of products under the guidance of this utility model. However, no matter what changes are made in their shape or structure, all technical solutions that fall within the scope of the claims of this utility model are within the protection scope of this utility model.
