Description

Technical Field

[0001] This utility model relates to the field of scooter technology, and in particular to a single-axis folding scooter. Background Technology

[0002] With the acceleration of urbanization and the continuous improvement of public transportation systems, the demand for smaller and more convenient personal transportation tools is growing. Among them, scooters, as a lightweight and environmentally friendly short-distance transportation tool, have been widely welcomed. To adapt to different usage scenarios, especially to improve their portability and storage efficiency, folding scooters have emerged on the market.

[0003] However, it has been found that traditional scooters use a complex multi-axis folding structure, which usually requires relatively complicated assembly and operation steps. Users may need certain skills and time to fold and unfold them, which affects the user experience to some extent. Utility Model Content

[0004] To address the problems mentioned above in the background art, this utility model provides a single-axis folding scooter.

[0005] The solution adopted by this utility model to solve its technical problem is: a single-axis folding scooter, including a pedal, a front wheel unit located at the front of the pedal, a rear wheel unit located at the rear of the pedal, and a control component. A rotating mechanism is provided between the pedal and the front wheel unit. The rotating mechanism includes a first connecting member fixed and inclined to the front wheel unit and a second connecting member fixed and inclined to the bottom surface of the front of the pedal. The first connecting member can rotate relative to the second connecting member. One end of the control component is fixedly connected to the side of the front wheel unit, and when the relative rotation angle of the first connecting member is controlled in a first range, it can drive the front wheel unit to turn left or right; and when the relative rotation angle of the first connecting member is controlled in a second range, it can fold the control component to the bottom of the pedal.

[0006] By adopting the above technical solution, a rotating mechanism is inclinedly arranged between the bottom of the pedal and the front wheel unit, and the control unit is fixed to the side of the front wheel unit. Thus, the front wheel unit can be controlled to turn left and right through the control unit, and the control unit can be folded to the bottom of the pedal. This simplifies the folding mechanism and makes the scooter more compact after folding.

[0007] Furthermore, the first connecting member is a rotating shaft, which is inclined toward the rear side of the pedal, and the second connecting member is a rotating seat, which has an assembly hole for accommodating the rotating shaft and supporting its rotation. The assembly hole is inclined toward the front side of the pedal and has a plurality of bearing components inside.

[0008] By adopting the above technical solution, the rotating shaft is inclined towards the rear of the pedal and supported by the mounting hole in the rotating seat. The mounting hole is also inclined towards the front, ensuring good concentricity of the rotating shaft and effectively reducing shaking and unnecessary friction during rotation.

[0009] Furthermore, the bottom surface of the rear of the pedal is provided with a fixing seat, the fixing seat has a number of slots, and the control component has a snap-fit ​​part for being embedded in the slot after folding. The snap-fit ​​part includes a snap hook part, and the fixing seat is also hinged with a movable snap ring, which is used to rotate and fix the snap hook part after the snap-fit ​​part is embedded in the slot, thereby locking the control component.

[0010] By adopting the above technical solutions, the snap-fit ​​component of the folded control component can be accurately embedded in the slot for positioning, and the control component can be effectively locked by rotating the movable snap ring to fit its snap hook, thus ensuring its stability in the folded state.

[0011] Furthermore, the control component includes a telescopic riser, which includes a fixed part that is fixedly connected at one end to the front wheel unit, a movable part that slides through the fixed part, and a locking part for locking the movable part into the fixed part.

[0012] By adopting the above technical solution, the control component can be flexibly adjusted in height according to the user's height requirements, and the telescopic riser can be locked in different height positions by the locking part.

[0013] Furthermore, the control assembly also includes a controller located at the top of the telescopic riser, an electric drive device electrically connected to the controller is provided at the bottom of the pedal, the rear wheel unit is a drive wheel electrically connected to the controller and the electric drive device, and the controller has a handheld part for easy gripping.

[0014] By adopting the above technical solution, by installing a controller at the top of the telescopic riser and configuring a drive wheel at the bottom of the pedal that is electrically connected to the controller and the electric drive device, the user can control the scooter by holding the hand of the controller with one hand, and the scooter can move automatically through the built-in electric drive device.

[0015] Furthermore, a braking mechanism is provided on the rear side of the pedal. The braking mechanism includes a rear wheel cover plate rotatably connected to both sides of the pedal and a brake pad fixed to the bottom of the rear wheel cover plate and located above the rear wheel unit. The brake pad is used to make the rear wheel cover plate press down so that the brake pad contacts the rear wheel unit, thereby braking.

[0016] By adopting the above technical solution, the rear wheel cover can be rotated and moved down simply by stepping on the rear wheel cover at the rear end. This allows the brake pads fixed at the bottom of the rear wheel cover to contact the rear wheel unit located below it and generate friction, thereby achieving the braking effect.

[0017] Furthermore, the rear sides of the pedal are provided with limiting posts, and each limiting post is fixedly fitted with a return spring for resetting the rear wheel cover. The beginning of each return spring is fixedly connected to the pedal, and its end is fixedly connected to the rear wheel cover.

[0018] By adopting the above technical solution, when the rear wheel cover is stepped on for braking, the return spring is stretched, and when the external force disappears, the spring elastic force causes the rear wheel cover to return to its original position.

[0019] Furthermore, it also has a wireless charging mechanism for charging the controller, the wireless charging mechanism including a receiver on the controller and a transmitter on the rear side of the pedal, the receiver being able to align with the transmitter after folding, thereby charging the controller.

[0020] By adopting the above technical solution, when the control component is folded, the receiver on the controller can accurately align and contact the transmitter, thereby realizing the wireless charging function.

[0021] Furthermore, a headlight is provided on the front side of the pedal and a taillight is provided on the rear side. Both the headlight and taillight are electrically connected to the electric drive device and controller.

[0022] By adopting the above technical solutions, the visibility of users riding at night or in dimly lit environments can be improved, thereby enhancing safety.

[0023] In summary, the beneficial effects of this utility model are as follows:

[0024] 1. This utility model has a single-axis rotating folding mechanism consisting of a rotating shaft inclinedly arranged on the front wheel unit and a rotating seat inclinedly arranged on the bottom surface of the front of the pedal to support its rotation. It is fixedly connected to the side of the front wheel unit by a control component, which can control the scooter to turn left and right. At a specific control angle, it can be folded to the bottom of the pedal, which can reduce the overall length of the scooter and make the scooter more compact after folding, making it easier for users to store and carry in small spaces.

[0025] 2. This utility model, by setting a locking mechanism consisting of a fixed base, a slot, a snap-fit ​​component, and a movable snap ring, enables the snap-fit ​​component of the control component to be accurately embedded in the slot for positioning after folding, and can effectively lock the control component by rotating the movable snap ring to fit its snap hook, thus ensuring its stability in the folded state.

[0026] 3. This utility model provides a braking mechanism consisting of a rear wheel cover plate, brake pads, and a return spring at the rear end of the pedal. By simply stepping on the rear wheel cover plate, the rear brake pads can make contact with the rear wheel unit located below it and generate friction, thereby achieving the braking effect. When the external force disappears, the elastic force of the spring causes the rear wheel cover plate to return to its original position.

[0027] 4. This utility model provides a wireless charging mechanism by setting a receiver on the controller and a transmitter on the back of the pedal, which can conveniently wirelessly charge the controller when it is folded.

[0037] To make the content of this utility model easier to understand, the present utility model will be further described below with reference to specific embodiments and accompanying drawings.

[0038] It should be noted that the terms "center," "upper," "lower," "front," "rear," "left," "right," "inner," and "outer" used herein to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Unless otherwise stated, "a plurality of" means two or more.

[0039] Unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] like Figures 1 to 7As shown, this embodiment provides a single-axis folding scooter, which includes a footboard 1, a front wheel unit 2 located at the front of the footboard 1, a rear wheel unit 3 located at the rear of the footboard 1, and a control assembly 4. In this embodiment, a rotating mechanism 5 is provided between the footboard 1 and the front wheel unit 2. The rotating mechanism 5 includes a first connecting member fixed and inclinedly disposed on the front wheel unit 2 and a second connecting member fixed and inclinedly disposed on the bottom surface of the front part of the footboard 1. The first connecting member can rotate relative to the second connecting member. One end of the control assembly 4 is fixedly connected to the side of the front wheel unit 2. When the relative rotation angle of the first connecting member is controlled in a first range, the control assembly 4 can drive the front wheel unit 2 to turn to the left or right. When the relative rotation angle of the first connecting member is controlled in a second range, the control assembly 4 can be folded to the bottom of the footboard 1.

[0041] In this embodiment, the front wheel unit 2 and rear wheel unit 3 are respectively provided on the bottom surface of the front and rear parts of the pedal 1, and a control component 4 is also provided at the front end of the pedal 1 for the user to support and control, thus forming a scooter. To increase the scooter's flexibility, a steering mechanism is provided between the pedal 1 and the front wheel unit 2 in this embodiment. The steering mechanism includes a first connector and a second connector. The first connector is fixedly mounted on the front wheel unit 2 in an inclined position, while the second connector is fixedly mounted on the bottom surface of the front part of the pedal 1 in an inclined position, and is configured such that the first connector can rotate relative to the axis of the second connector. The tail end of the control component 4 is fixedly connected to one side of the front wheel unit 2. When the control component 4 is in its original position, both the front wheel unit 2 and the control component 4 are parallel to the axis of the pedal 1, ensuring that the scooter can travel in a straight line. Specifically, the user can control the control component 4 to rotate to the left and right by operating it from the top. Because the tail end of the control component 4 is fixedly connected to one side edge of the front wheel unit 2, when the control component 4 rotates to the left or right at an angle within the first range of 0 to 90 degrees (usually between 30 and 45 degrees), this angle represents the angle between the front wheel unit 2 and the axis of the pedal 1, allowing the scooter to complete the corresponding left or right turn. When the control component 4 rotates to the left or right at a second range of 170 to 190 degrees (usually close to 180 degrees), the scooter can rotate from the left or right side of the pedal 1 and fold to the bottom of the pedal 1, thus greatly reducing the overall length of the scooter. This makes it easier for users to store the scooter in smaller spaces (such as a car trunk or a corner of their home) or to carry it easily.

[0042] The first interval mentioned above can also be any interval within which the front wheel unit 2 can turn left or right relative to the pedal 1, while the second interval is any interval within which the control component 4 can fold to the bottom of the pedal 1. The value ranges of the first and second intervals mentioned above are only for reference and example. The first and second intervals can be selected according to actual needs, and the tilt angles of the first and second connecting members, as well as the positional relationship of the steering mechanism, the front wheel unit 2 and the control component 4, can be adjusted accordingly. This embodiment does not impose any limitations.

[0043] like Figure 4 as well as Figure 5 As shown, in this embodiment, the first connecting member is a rotating shaft 51, which is inclined towards the rear of the pedal 1. The second connecting member is a rotating seat 52, which has a mounting hole 53 for accommodating the rotating shaft 51 and supporting its rotation. The mounting hole 53 is inclined towards the front of the pedal 1 and contains several bearing components 54. Specifically, in this embodiment, the first connecting member is a rotating shaft 51 fixedly mounted on the housing of the front wheel unit 2, which is inclined at approximately 45 degrees towards the rear of the pedal 1. The second connecting member is a rotating seat 52 fixedly mounted on the ground in front of the pedal 1, which has a mounting hole 53 inclined towards the front and capable of accommodating the rotating shaft 51. Two bearings are installed in the hole, with the outer rings of the two bearings abutting against the inner wall of the mounting hole 53, and their inner rings in close contact with the rotating shaft 51, so that the rotating shaft 51 can drive the inner rings of the bearings to rotate together. This provides good concentricity and effectively reduces shaking and unnecessary friction during rotation.

[0044] like Figure 3 as well as Figure 4As shown, in this embodiment, the bottom surface of the rear of the pedal 1 is provided with a fixing seat 11. The fixing seat 11 has a plurality of slots 12, and the control component 4 has a locking member 13 for being embedded in the slots 12 after folding. The locking member 13 includes a hook portion 131, and a movable retaining ring 14 is also hinged to the fixing seat 11, which is used to rotate the fixed hook portion 131 after the locking member 13 is embedded in the slot 12, thereby locking the control component 4. Specifically, in this embodiment, the locking member 13 is fixedly provided on the control component 4, and the locking member 13 is specifically arranged on the side of the control component 4 facing the bottom surface of the pedal 1 after folding. The bottom surface of the rear of the pedal 1 is provided with a corresponding fixing seat 11, and one or more slots 12 are provided on the fixing seat 11. These slots 12 match the locking member 13, so that when the control component 4 is folded, the locking member 13 can be accurately embedded in the slot 12, thereby achieving positioning. Furthermore, to achieve a better locking effect, a hook portion 131 is provided on the latching component 13, and a retaining ring that can rotate relative to the retaining base 11 is installed on the retaining base 11. When the control component 4 is folded and the latching component 13 fits into the latching slot 12, the retaining ring can be rotated to lock the control component 4 around the hook portion 131. At this time, the user can simply lift the control component 4 by hand to achieve a portable effect.

[0045] like Figure 1 as well as Figure 6 As shown, the control component 4 in this embodiment includes a telescopic riser 41. The telescopic riser 41 includes a fixed part 411 with one end fixedly connected to the front wheel unit 2, a movable part 412 slidably passing through the fixed part 411, and a locking part 413 for locking the movable part 412 into the fixed part 411. The fixed part 411 serves as the basic structure of the telescopic riser 41. One end of it is fixedly connected to the front wheel unit 2 of the scooter, and its interior has a sliding space for the movable part 412 to slide. The movable part 412 passes through the sliding space inside the fixed part 411 and can slide up and down along the fixed part 411 to adjust the height of the control component 4 to meet the needs of different users. The locking part 413 uses a quick-release locking device, allowing users to easily adjust the height without tools.

[0046] like Figure 5 as well as Figure 6As shown, the control assembly 4 of this embodiment also includes a controller 42 located at the top of the telescopic riser 41. An electric drive device 8 electrically connected to the controller 42 is also located at the bottom of the pedal 1. The rear wheel unit 3 is a drive wheel electrically connected to the controller 42 and the electric drive device 8. The controller 42 has a handgrip 421 for easy gripping. The controller 42 is fixed at the top of the telescopic riser 41, located on either the left or right side of the top, and has a handgrip 421 for easy gripping by the user, allowing for one-handed operation of the scooter. The electric drive device 8, which integrates a battery box and the main board of the controller 42, is located at the bottom of the pedal 1. The rear wheel unit 3 is a drive wheel driven by the controller 42 and the electric drive device 8, enabling the scooter of this embodiment to move automatically by electric power.

[0047] like Figure 7 As shown, a braking mechanism 6 is also provided on the rear side of the pedal 1 in this embodiment. The braking mechanism 6 includes a rear wheel cover plate 61 rotatably connected to both sides of the pedal 1 and a brake pad 62 fixed to the bottom of the rear wheel cover plate 61 and located above the rear wheel unit 3. This mechanism allows the user to step on the rear wheel cover plate 61 to make the brake pad 62 contact the rear wheel unit 3, thereby braking. The braking mechanism 6 mainly consists of two parts: the first part is the rear wheel cover plate 61, which is rotatably connected to both sides of the pedal 1, allowing the rear wheel cover plate 61 to rotate freely within a certain range. The second part is the brake pad 62, which is fixedly installed at the bottom of the rear wheel cover plate 61 and located above the rear wheel unit 3. The user only needs to step on the rear wheel cover plate 61 at the rear end to rotate and move it downwards. In this way, the brake pad 62 fixed to the bottom of the rear wheel cover plate 61 will contact the rear wheel unit 3 below, generating friction and thus achieving a braking effect, slowing down or stopping the scooter.

[0048] Furthermore, in this embodiment, the rear sides of the pedal 1 also have limiting posts 63, and each limiting post 63 is fixedly fitted with a return spring 64 for resetting the rear wheel cover 61. The starting end of each return spring 64 is fixedly connected to the pedal 1, and its ending end is fixedly connected to the rear wheel cover 61. Specifically, limiting posts 63 are fixedly provided at fixed positions on both sides of the pedal 1. These limiting posts 63 are perpendicular to the axial direction of the pedal 1, and a return spring 64 is fitted on the limiting post 63. One end of the return spring 64 is provided with a limiting part to limit its displacement. The starting end of the return spring 64 is firmly connected to the pedal 1 to ensure that the return force on the pedal 1 is always maintained regardless of the position of the rear wheel cover 61. The ending end of the return spring 64 is firmly connected to the rear wheel cover 61, which means that when an external force is applied to the rear wheel cover 61, the return spring 64 will be stretched due to the displacement of the rear wheel cover 61. When the external force disappears or decreases, the elastic restoring force of the return spring 64 will cause the rear wheel cover 61 to return to its original position where it is firmly connected to the pedal 1.

[0049] like Figure 5 as well as Figure 7 As shown, the scooter in this embodiment also has a wireless charging mechanism 7 for charging the controller 42. The wireless charging mechanism 7 includes a receiver 71 on the controller 42 and a transmitter 72 located at the rear of the footboard 1. The receiver 71 can align with and contact the transmitter 72 after folding, thereby charging the controller 42. Specifically, in this embodiment, the controller 42 is provided with a wireless charging receiver 71, while the rear of the footboard 1 is provided with a wireless charging transmitter 72 electrically connected to the battery box; the two together constitute the wireless charging mechanism 7. When the control assembly 4 is folded, the receiver 71 on the controller 42 can precisely align with and contact the transmitter 72, thereby realizing the wireless charging function.

[0050] like Figure 1 As shown, in this embodiment, a headlight 15 is provided on the front side of the pedal 1, and a taillight 16 is provided on the rear side. Both the headlight 15 and the taillight 16 are electrically connected to the electric drive unit 8 and the controller 42. A headlight 15 is designed at the front end of the pedal 1, and a taillight 16 is designed at the rear end of the pedal 1. Both the headlight 15 and the taillight 16 are connected to the electric drive unit 8 and its associated controller 42 via electrical wiring. This improves the user's visibility while riding at night or in low-light conditions, effectively enhancing safety.

[0051] In summary, the beneficial effects of this embodiment are as follows: This embodiment constructs a single-axis rotation and folding mechanism by tilting a rotating shaft 51 on the front wheel unit 2 and tilting a rotating seat 52 on the bottom front surface of the pedal 1 to support its rotation. This mechanism is fixedly connected to the side of the front wheel unit 2 via the control component 4, allowing the scooter to turn left and right. At a specific control angle, it can be folded to the bottom of the pedal 1, reducing the overall length of the scooter and making it more compact after folding, facilitating storage and carrying in confined spaces. The locking mechanism, consisting of a fixed seat 11, a slot 12, a latching member 13, and a movable retaining ring 14, allows the latching member 13 of the control component 4 to be accurately embedded in the slot 12 for positioning after folding. Furthermore, rotating the movable retaining ring 14 to engage its hook portion 131 effectively locks the control component 4, ensuring its stability in the folded state. A braking mechanism 6, consisting of a rear wheel cover 61, brake pads 62, and a return spring 64, is installed at the rear end of the pedal 1. By simply stepping on the rear wheel cover 61, the rear brake pads 62 can contact the rear wheel unit 3 located below it, generating friction and achieving a braking effect. When the external force disappears, the spring's elasticity returns the rear wheel cover 61 to its original position. Furthermore, a wireless charging mechanism 7 is constructed by a receiver 71 on the controller 42 and a transmitter 72 located at the rear of the pedal 1, allowing for convenient wireless charging of the controller 42 when it is folded.

[0052] The embodiments described above are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and modifications made by those skilled in the art based on this utility model shall fall within the scope of protection of this utility model.
