Detailed Description of the Invention

[0059] In some embodiments, the present invention relates to personal vehicles, and more specifically, but not exclusively, to multi-purpose vehicles. <Overview>

[0060] People of all ages face mobility challenges due to illness, age, medical conditions, surgery, or recovery from injury. A wide variety of mobility devices exist to assist with mobility, including walkers, wheelchairs, and powered scooters. While each is designed to support specific problems or activities, their scope of benefit is narrow, and each single device tends to limit the range of activities a user can engage in using that particular device.

[0061] Therefore, in order to reduce the physical, emotional, and economic burden of purchasing mobility devices, there is a need for mobility devices that can be converted from one form to another to support people in various situations, in line with improvements or declines in physical strength and abilities.

[0062] The present invention relates to a motor-driven scooter that can be reversibly converted into a cart in some embodiments. In some embodiments, the cart may include a power-assisted cart and / or an unpowered push cart and / or a remotely controlled cart and / or an auto-follow cart and / or an independent robotic cart. Optionally, the scooter is configured for use by persons with mild physical limitations, and / or persons who have difficulty walking long distances and / or uneven terrain (such as outside curbs). For example, a user of a mobility scooter may be able to walk indoors (e.g., along store aisles) with or without limited assistance (e.g., using a walker). For example, a person may use the device as a mobility scooter to go to a store, but in a more crowded store, they may use it as a shopping cart and / or walker to stabilize themselves. For example, a healthy person may also find this function useful.

[0063] In some embodiments, the vehicle may include a front and a rear section interconnected by a deformable coupling. For example, the coupling may be extendable and / or retractable. Optionally, the front section may include a deformable steering system. For example, the steering system may have a forward position (e.g., when used in scooter mode [e.g., scooter mode may include stand-up scooter mode, mode in which the user rides using a bicycle-type seat, and / or mode in which the user sits on a bench and / or full seat]) and / or a rear position on the front of the vehicle. For example, the steering column and / or handle of the steering system may extend behind the rear wheels in pushcart mode.

[0064] In some embodiments, the pushcart mode may have a shorter wheelbase than one or more possible scooter modes. For example, the wheelbase of the scooter mode may be 1.1 to 1.3 times and / or 1.05 to 1.1 times and / or 1.3 to 1.8 times and / or 1.8 to 2.5 times the wheelbase of the pushcart mode. For example, the wheelbase of the pushcart mode may be in the range of 70 to 90 cm and / or 90 to 150 cm and / or 150 to 250 cm and / or 40 to 70 cm. For example, the wheelbase of the scooter mode may be in the range of 90 to 110 cm and / or 110 to 170 cm and / or 170 to 270 cm and / or 60 to 90 cm. For example, the wheelbase of the scooter mode may be 10 to 30 cm and / or 5 to 10 cm and / or 30 to 100 cm larger than the wheelbase of the pushcart mode.

[0065] In some embodiments, the width of the vehicle may be in the range of 60-100 cm and / or 30-60 cm and / or 100-200 cm. In some embodiments, the height of the vehicle may be in the range of 70-120 cm and / or 40-70 cm and / or 120-200 cm. In some embodiments, the vehicle may have footrests for standing and / or for placing feet while seated. For example, the footrest height in scooter mode may be in the range of 5-15 cm and / or 2-5 cm and / or 15-30 cm.

[0066] In some embodiments, the vehicle may include one or more motors, such as electric motors. Optionally, each motor may have an output in the range of 100–300W and / or 300–600W and / or 600–1000W. Optionally, the combined power of the motors may be in the range of 200–600W and / or 600–1200W and / or 1200–3000W. Optionally, the vehicle may include a battery. For example, the battery may have a capacity of 10–20Ah and / or 5–10Ah and / or 20–40Ah.

[0067] In some embodiments, the weight of the vehicle may be in the range of 20-60 kg and / or 10-20 kg and / or 60-120 kg. Optionally, the weight ratio between the front and rear may be 1.2-0.8 and / or 0.5-0.8 and / or 1.2-2.0. <Exemplary Embodiment>

[0068] Before describing in detail at least one embodiment of the present invention, it should be understood that the application of the present invention is not necessarily limited to the details of the configuration and arrangement of components and / or methods described below and / or illustrated in the drawings and / or embodiments. The present invention can be realized in other embodiments or carried out in various ways.

[0069] Figure 1 is a schematic perspective view of a vehicle in scooter mode according to an embodiment of the present invention. Figure 2 is a schematic perspective view of a vehicle in pushcart mode according to an embodiment of the present invention. In some embodiments, the vehicle can be reversibly converted from scooter mode (e.g., Figure 1) to pushcart mode (e.g., Figure 2). Optionally, the vehicle comprises a front section 106. For example, the front section may include a steering system. For example, the steering system may include one or more steerable front wheels 128. Optionally, the front wheels and / or the entire front section may rotate around a steering column 112 for steering. Alternatively or additionally, steering may be hub-centered. For example, the front section may remain in line with the rear section while the wheels 128 rotate around their own axes. For example, the vehicle may include a rack and pinion system and / or a variable ratio steering system.

[0070] In some embodiments, the length of the steering column 112 may be varied. For example, the column 112 may be nested. The steering system optionally includes one or more handles and / or steering wheels and / or steering sticks. For example, the vehicle may be steered by turning the handlebar 102 and / or by turning the walking handle 108 left and right.

[0071] In some embodiments, the vehicle includes a rear section that is movable relative to the front section. Optionally, the rear section comprises one or more rear wheels 124. Additionally or alternatively, the rear section may include one or more footboards 134. Additionally or alternatively, the rear section may include a seat and / or seat support port 136. For example, the support section may include a port 136 for inserting a seat post. Alternatively or additionally, there may be a permanently mounted seat.

[0072] In some embodiments, the rear is connected to the front and / or steering system by a deformable coupling system. For example, the coupling system may include one or more spacers. For example, the spacers may include bars 118, 132 and / or coupling section 122. In some embodiments, the spacers may be deformable. For example, the bars 118, 132 and coupling section 122 may be interconnected by hinges 114, 130. Optionally, a lockable coupling section 122 secures the vehicle to one or another configuration. For example, the coupling system may be deformable between a scooter mode with a long wheelbase and / or a pushcart mode with a short wheelbase. Optionally, when the wheelbase is deformed between the scooter mode and the pushcart mode, the steering column 112 may be tilted rearward. Additionally or alternatively, a steering stick (e.g., a walking handle 108) may extend rearward from the steering column. For example, in pushcart mode, the steering stick (e.g., handle 108 and / or handlebar 102) may extend behind the rear wheel 124. Additionally or alternatively, in scooter mode, the steering column 112 may be tilted vertically (e.g., more forward and / or more vertical than in pushcart mode).

[0073] In embodiments, the coupling system transforms into a pushcart mode and / or shortens the axle-to-axle distance of the vehicle by folding bars 118, 132 and / or coupling section 122 around hinges 114, 130. For example, a spacer connected to the front (e.g., bars 118, 132) may be folded upward by pivoting upward from the front connection (e.g., at hinges 114 and / or 130). Additionally or alternatively, a spacer connected to the rear (e.g., coupling section 122) may be folded upward (e.g., around the axle of the rear wheel 124). Optionally, the front moves closer to the rear by folding the coupling section. For example, the front spacers (e.g., bars 118, 132) are folded toward the rear spacers (e.g., coupling section 122) around a pivot (e.g., the axle of the rear wheel 124). Alternatively or additionally, the connecting section may be nesting and / or bending and / or accordion-like folding and / or lateral folding, etc. Optionally, the connecting section 122 is transformable into and / or lockable into two configurations to provide a scooter mode and a pushcart mode.

[0074] In some embodiments, spacers (bars 132, 118 and coupling 122) and / or connectors (e.g., hinges 130, 114) are configured such that the steering column 112 tilts backward as the axle distance decreases. For example, the lower front spacer (e.g., bar 132) is connected closer to the pivot point (e.g., the axle of the rear wheel 124) of the rear spacer (e.g., coupling 122) than the upper front spacer (e.g., bar 118), so that when the coupling is folded, the upper part of the steering column 112 is pulled further backward than the lower part of the steering column 112, and / or tilts the steering column 112 backward.

[0075] In one embodiment, in scooter mode (for example, as shown in Figure 1), the height of one or more footboards 134 from the ground is reduced to allow for easy mounting and dismounting of the scooter and / or to stabilize and / or ensure safety while riding. For example, one or more footboards 134 are designed to deform in a way that increases the minimum ground clearance in pushcart mode. For example, a footboard 134 may pivot upward by rotation around a pivot (for example, the axle 138 of the rear wheel 124 as illustrated in Figure 2). In one embodiment, one or more footboards are foldable.

[0076] Optionally, the vehicle includes an accessory support 126. For example, the accessory support 126 may be connected to the front. Optionally, the support 126 rotates with the front wheels during steering. Alternatively or additionally (for example, in the case of hub-center steering), the orientation of the support 126 may be fixed during steering.

[0077] Optionally, the vehicle may include one or more motors. For example, the vehicle may include dual motors on the front wheels 128 of the vehicle. Additionally or alternatively, one or more motors may be mounted on the rear wheels 124 of the vehicle. Alternatively or additionally, the motors may be mounted on the vehicle's chassis (e.g., front and / or rear) and / or drive the wheels 124,128 via a drive chain.

[0078] In embodiments that convert to pushcart mode, the walking handle 108 is extended backward toward the user pushing the cart. For example, the handle 108 pivots upward toward the user toward the steering column 112 located below the handlebar 102 of the steering system from its stowed position (e.g., Figures 1, 4, and 7), and is then locked in place (e.g., Figures 2, 5, and 8). For example, the hands holding the handle may become tired after walking for a long time. Therefore, the locking mechanism of the walking handle allows the user to place their hands on the handle and / or steer more easily (e.g., Figure 5). The height and / or angle of the walking handle 108 is optionally adjustable 110, as is the height and / or angle of the handlebar, and / or the length of the linking system, to suit individual users. Alternatively or additionally, the handlebar 102 may be folded backward in pushcart mode for storage and / or transport purposes using an adjustable hinge 110.

[0079] In one embodiment of the pushcart mode (for example, Figures 2 and 5), the length of the vehicle is shortened by the above-described modification, and the walking handle 108, which is connected to the handlebar 102 and held by the user, is made as short as possible so that it is easy to steer with one hand and / or so that the user's feet do not hit the footboard 134 while walking.

[0080] In one embodiment, in scooter mode, the vehicle is long enough (e.g., Figures 1, 3, and 4) for the user to stand / sit in front of the rear wheel accelerator, thus reducing the risk of tipping over backward, especially on steep inclines. In one embodiment, the front of the scooter is positioned in front of the steering system, providing further stability.

[0081] In some embodiments, the throttle and / or other control units may be located on one or both of the left and / or right handlebars 102 and / or the control panel 104 and / or the pedestrian handle 108. In some embodiments, the braking system automatically stops the scooter when the throttle is released and / or automatically sets the parking brake when the vehicle is stopped (optionally after a certain period of time). Alternatively or additionally, a manual brake engagement mechanism may be present.

[0082] Figure 3 is a schematic perspective view of a scooter with a bicycle-like seat according to one embodiment of the present invention. Figure 4 is a schematic perspective view of a scooter with a mobile scooter / tractor-like seat according to one embodiment of the present invention. In one embodiment, riding is performed in scooter mode, while sitting on a high bicycle-like seat 302 (e.g., in Figure 3) and / or while sitting on a mobile scooter / tractor-like seat 402 (e.g., in Figure 4), optionally in a standing position on one or more footboards 134 (e.g., in Figure 1). The bicycle-like seat 302 or the mobile scooter / tractor-like seat 402 is optionally supported by a height-adjustable, nesting tubular seat support 304. The support 304 is optionally secured to a coupling system by a connector. Optionally, the connection may be reversible. For example, the connector may include a port 136. Optionally, the port 136 is located at the rear of the scooter.

[0083] Figure 5 is a schematic perspective view of a vehicle in pushcart mode with accessories (in this exemplary case, a child seat and a shopping cart) according to one embodiment of the present invention.

[0084] In one embodiment, the pushcart mode is optionally powered or unpowered (e.g., Figure 9). In one embodiment, the pushcart mode is configured to be pushed manually and / or to function as a walker in unpowered mode (e.g., Figure 5).

[0085] Figure 6 is a schematic perspective view of a scooter with a bicycle-like seat equipped with accessories (in this exemplary case, a child seat and a shopping cart) according to one embodiment of the present invention. In one embodiment, a control panel 104 allows the user to preset or adjust the speed in scooter mode and / or push-cart powered mode. For example, the panel 104 may be mounted on the handlebars 102. In one embodiment, while in scooter mode, the speed of the scooter is controlled by the user with a throttle. In one embodiment, while in push-cart powered mode, the movement of the cart is controlled by the user with push buttons on the walking handle 108.

[0086] Figure 7 is a schematic perspective view of the walking handle in the retracted position according to one embodiment of the present invention. Figure 8 is a schematic perspective view of the walking handle in the extended position according to one embodiment of the present invention. When the vehicle is in pushcart unpowered mode, it may be difficult to push it up steep slopes, especially when the load is heavy. Additionally or alternatively, it may be difficult to stop it on steep slopes. Optionally, the user may be able to switch to powered mode. For example, there may be a switch on the control panel. In some cases, this operation may not be easy under pressure. Optionally, in one embodiment, the motor may be activated by pressing button 802 in pushcart mode. In one embodiment, the walking handle 108 has one button 802 on each side for activating the motor when in pushcart mode, and it is possible to switch hands while walking in powered mode. Alternatively or additionally, the walking handle may have a control unit for the brake system (e.g., a brake lever and / or a dead man's switch that automatically applies the brakes to the vehicle when the user releases it).

[0087] In one embodiment, when the button 802 on the walking handle is released in pushcart mode, the vehicle automatically stops, and / or the parking brake is automatically activated after stopping.

[0088] In one embodiment, the vehicle's motor is powered by a battery 120. For example, the battery 120 may be held in place by a battery support. Optionally, the battery support may be located at the front of the vehicle. The battery 120 is optionally removable and / or rechargeable (similar to, for example, a battery in an electric bicycle). The motor and / or motor driven by the battery is optionally located inside the front and / or rear wheels.

[0089] In one embodiment, the vehicle is directed remotely, automatically follows the user, and / or manually while in pushcart powered mode. Optionally, the vehicle may be directed remotely (remote control mode) and / or automatically follows the user (follow-me mode) in any mode. For example, the vehicle may be directed remotely and / or automatically follows the user while in scooter mode (e.g., with the coupling extended and / or the steering column oriented vertically). Alternatively or additionally, the vehicle may be directed remotely and / or automatically follows the user while in pushcart mode (e.g., with the coupling retracted (e.g., folded) and / or the steering column oriented rearward).

[0090] In one embodiment, accessory support units 116, 126 are configured to carry a shopping basket or cart 502, a golf bag, one or more child seats 504, an umbrella, a drink bottle or thermos, other types of luggage, or a combination thereof, in both scooter mode (e.g., Figure 5) and / or pushcart mode (e.g., Figure 6).

[0091] Figure 9 is a flowchart illustrating the reversible transformation of a vehicle between scooter mode, pushcart powered mode, and / or pushcart unpowered mode according to one embodiment of the present invention.
