[0002] This application is an international application filed on October 27, 2021, with application number PCT / IL2021 / 051276 entitled “SCOOTERWITH AUTOMATIC TILT OF THE STEERING POST”, which entered into the U.S. national phase under 35 U.S.SC § 371. This application claims priority and benefit to Israeli Patent Application No. 278369, filed on October 28, 2020. The contents of both applications are incorporated herein by reference in their entirety. Technical Field

[0003] This disclosure relates to a scooter with two front wheels, and more specifically, to a scooter with two front wheels controlled by a steering column connected to a steering mechanism such that when the steering column pivots, the steering mechanism synchronizes the tilt of the steering column to tilt toward the inner periphery of the turning curve. The scooter may also be a folding scooter. Background Technology

[0004] A scooter is a type of vehicle that is typically small in size and allows riders to carry it by hand when not in use. In some cases, it can also be folded from the riding position to a carry / storage position and vice versa (hereafter referred to as “folding”).

[0005] US Patent 9,272,739 to Amir Zaid et al. discloses a scooter including a deck section mounted on a pair of front wheels; at least one tail section foldably coupled to the deck section and narrower than the deck section, and mounted on at least one rear wheel to provide stability to the deck section. The scooter also includes a steering column coupled to the front wheels and foldable relative to the deck section.

[0006] Costel Dragomir's U.S. Patent US10322767 discloses an improved pedal-driven scooter that may have a main frame, a jointed frame, a front balance and steering mechanism, one or two front steering wheels, a rear drive wheel, and a drive mechanism. The pedals are pushed rearward and move independently of each other within an adjustable angle range. The drive mechanism converts the alternating motion of the pedals into a further amplified unidirectional rotation, driving the actual wheels. A tilt control mechanism allows the rider to maintain a riding position when the vehicle is stopped. The scooter can be folded, with the jointed frame pivoting at both ends so that the rear wheel rests between or near the front wheels, and the scooter can be carried like carry-on luggage. The scooter can also be further folded for storage via folding hinges connecting the lower and upper parts of the front steering mechanism. The term "scooter" as used herein in the specification and claims refers to any of various vehicles, scooters, motorized scooters, mopeds, etc., or any transport device having a steering column and at least two front wheels for carrying more than one rider.

[0007] One drawback of existing scooters is their small size, which can lead to unsafe riding. Some existing scooters have a steering column that remains upright when turning. Therefore, when riding a two-wheeled vehicle and turning, the wheel positioned on the inner edge of the curve often loses traction due to centrifugal force, including being lifted into the air. Furthermore, the front wheel tilts towards the inner edge of the curve, further contributing to the loss of traction.

[0008] Therefore, it is necessary and advantageous to have a mechanism that, when riding at a reasonable speed, automatically and synchronously tilts the steering column toward the inner periphery of the turning curve when the rider pivots the steering column to make a turn, while keeping the two front wheels upright. Even more advantageous is that the scooter can be folded and stored, or placed in a trolley and carried like carry-on luggage. Summary of the Invention

[0353] The teachings provided herein can be applied to other systems, not just those described herein. Elements and actions of the various embodiments described above can be combined to provide further embodiments.

[0354] According to one aspect of this disclosure, a scooter with two front wheels is provided, the front wheels being controlled by a steering column, which is part of a steering mechanism. When the steering column rotates, the steering mechanism synchronously tilts the steering column to tilt to one side towards the inner periphery of the turning curve. Furthermore, the scooter's standboard is configured to tilt to one side towards the inner periphery of the turning curve. Additionally, the steering mechanism is designed to keep both front wheels upright, including during turning.

[0355] According to another aspect of this disclosure, a foldable scooter is provided, which can be folded into a trolley, including a deck assembly. The foldable scooter may also include a removable bag, wherein the scooter can be folded into a trolley load rack, including the deck assembly and the removable bag.

[0356] Now refer to the accompanying drawings. According to the various embodiments of this disclosure, Figure 1 The schematic diagram illustrates a first non-limiting example embodiment of the scooter 100, including a steering column 110, a deck assembly 120 with a stand-up plate 121 and a rear wheel assembly 170, a steering mechanism 130, and an optional removable bag 199, wherein the steering column 110 is in a straight, upright position. The stand-up plate 121 is configured to tilt to one side toward the inner periphery of a turning curve and is configured to support the rider who would normally stand on it.

[0357] The steering column 110 may include a handlebar 118 with two handlebars 116 to assist the rider of the scooter 100 in turning left or right by pivoting the steering column 110 accordingly. A primary aspect of this disclosure is to provide a mechanism in which, when the steering column 110 pivots, it is also forced to tilt to one side toward the inner periphery of the turning curve. Typically, the pivot axis 115 of the steering column 110 is operatively located on the longitudinal axis 105 of the scooter 100.

[0358] Therefore, the steering mechanism 130 enables the rider to turn the scooter 100 to the left or right as he / she wishes when turning the steering column 110. Figure 2 The schematic diagram shows a scooter 100 according to various embodiments of the present disclosure in the following state, wherein the steering column 110 pivots to the left along direction 117 and thus also tilts to the left. Figure 3 This is a rear-view perspective view of a scooter 100 according to several embodiments of the present disclosure, wherein the steering column 110 pivots to the right and thus also tilts to the right. Tilt measurement is defined at a constant pre-construction rate. In one embodiment, the steering column 110 is subdivided into an upper column 112 and a lower column 114, wherein the upper column 112 slides retractably on the lower column 114.

[0359] Steering mechanism 130 also includes a pair of front wheels 132 interconnected with steering column 110 via the steering mechanism, wherein when steering column 110 pivots, the front wheels (132) L 132 R Each of them also pivots in the same direction via wheel pivoting mechanism 150, such as Figure 4 As shown. Figure 4 It is based on several schemes disclosed herein, such as Figure 3 The diagram shows a top perspective view of the front portion of a scooter 100, in which a non-limiting example of the wheel pivoting mechanism 150 is shown, based on the Ackerman Steering Principle (ASP). In such an ASP steering mechanism, the inner front wheel needs to rotate at a different angle than the outer wheel because they rotate at different radii. The ASP steering mechanism is a geometric arrangement of link components (e.g., 146, 154, 156) in the wheel pivoting mechanism 150, which is designed to rotate the inner and outer wheels at appropriate angles. Any other mechanism known in the art for coordinating the pivoting of two front wheels, such as in a car (but not, for example, a "carriage" mechanism), can be used. The exemplary wheel pivoting mechanism 150 includes a pivot receiving link component 146 that receives pivoting motion from the steering column 110, which is transmitted to the front wheels 132 via respective links 154. L and 132 R This is then transmitted to the corresponding linkage component 156, to which the corresponding front wheel 132 is rotatably attached. It should be understood that when the scooter 100 is in a turning position, the pivoting front wheel (132)... L 132 R Maintaining an upright orientation, where both wheels remain firmly on the road surface when traveling at a reasonable speed. Individual linkage components 156 (156) L 156 R It also includes the corresponding independent shaft 158 ​​(158)L 158 R When turning, the corresponding front wheel (132) L 132 R It pivots around this axis 158.

[0360] The rear wheel assembly 170 includes a rear wheel 172 rotatably connected to the rear axle. The rear wheel assembly 170 may also include a braking mechanism 174. The rear wheel assembly 170 may be operated by a motor, such as an electric motor (not shown).

[0361] Figure 5a This is a front view of the scooter 100, schematically illustrating a non-limiting example of the steering mechanism 130, where some parts (related to the steering column 110) have been removed for illustrative purposes only, and where the scooter 100 is shown in the deployed position. Similarly, Figure 6a This is a front view of the scooter 100, schematically illustrating the steering mechanism 130, where some obscured portions have been removed for illustrative purposes only, and where the scooter 100 is shown in a momentary left turn position.

[0362] Figure 5b This is a front view schematic diagram of the steering mechanism 130 of the scooter 100 shown in the unfolded position. Figure 5b The diagram illustrates the components involved in facilitating the scooter's left or right turn. Similarly, Figure 6b This is a front view schematic diagram of the steering mechanism 130 of the scooter 100, shown in a position at the moment of a left turn. Figure 6b The diagram illustrates participation in promoting scooter 100-degree turns (in...) Figure 6b The components shown in the non-limiting example are for left turns. The components of the steering mechanism 130 that utilize the automatic tilting of the steering column 110 to facilitate the steering of the scooter 100 include the steering column 110, a pair of front wheels 132, a tilt synchronization unit 140, and a pair of balance actuators 148 (shown as a pair of springs only, for example). The balance actuators 148 can also be implemented as, for example, a pair of pneumatic or hydraulic mechanisms.

[0363] The steering mechanism 130 further includes two frame elements: a pivoting frame element 188 and a non-pivoting frame element 180. The pivoting frame element 188 is configured to receive pivoting motion from the tilting synchronization unit 140, wherein the pivoting frame element 188 is pivotally connected to the non-pivoting frame element 180 at a bearing 185 arranged at the lateral center position of the non-pivoting frame element 180. The lower end 149 of the balance actuator 148... R 149 LIt is securely connected to the non-pivoting frame element 180 at the corresponding position, and the upper end 147 (147) of the balance actuator 148 is also securely connected to the non-pivoting frame element 180 at the corresponding position. R 147 L The balance actuator 148 is securely connected to the non-pivoting frame element 180 at the corresponding location. Therefore, the balance actuator 148 actuates the relative rotational drive force between the non-pivoting frame element 180 and the balance actuator 148, and applies a steering column return force on the steering column 110 opposite to the pivoting force applied by the driver. Once the driver reduces or releases the pivoting force (or turns the steering column 110 back), the balance actuator 148 pivots the steering column 110 toward its upright position. It should be understood that the balance actuator 148 can store the bias force by compressing the compressible balance actuator 148 or by pulling the balance actuator 148. This disclosure is described as if the balance actuator 148 were pulled, and the bias force attempts to return to its idle, unstretched state.

[0364] It should also be understood that the standing plate 121 attached to the pivot frame element 188 is configured to tilt to one side toward the inner periphery of the turning curve together with the pivot frame element 188 (see, for example, see...). Figure 6a ).

[0365] To further clarify the relationship between the steering mechanism 130 and the pivot frame element 188 and the non-pivot frame element 180, please refer to the following: Figure 7a and Figure 7b Steering tilt components 131a and 131b are introduced. Although Figure 7a Pivoting frame element 188 is also shown, but... Figure 7b For illustrative purposes only, pivot frame element 188 has been removed to expose tilt synchronization unit 140 and a pair of truncated rotating cones 142, which together facilitate automatic tilting of steering column 110 when it is pivoted. Figure 7c A detailed A view of the tilt synchronization assembly 155 is shown, which includes tilt synchronization units 140 and non-pivotable frame elements 180, which are pivotally connected to each other via shaft 185. Figure 8a This is a front view schematic diagram of the tilt synchronization unit 140 of the example steering mechanism 130, with the scooter 100 in the deployed position. The tilt synchronization unit 140 includes a column interface portion 141 having a rotation axis that coincides with the pivot axis 115 of the steering column 110, a pivot receiving link component 146, and a synchronization body 143. Figure 8b This is a side elevation view of an exemplary tilt synchronization unit 140 of the steering mechanism 130, with the scooter 100 shown in the unfolded position, in a straight, upright position. Figure 8c This is a top-view perspective view of the tilt synchronization unit 140 of the steering mechanism 130, with the scooter 100 shown in the unfolded position.

[0366] The synchronizing body 143 includes two arched walls 145, which are shown as part of an imaginary cylindrical thick wall 139 having a thickness W1 and an axis operatively coinciding with the pivot axis 115 of the steering column 110. The arched walls 145 are positioned at their base relative to an imaginary plane perpendicular to the pivot axis 115 at an angle α (see [reference]). Figure 8b It is diagonally truncated to form plane 144, including the right side 144. R And left side 144 L It should be noted that angle α can vary along plane 144. Plane 144 is also (relative to the pivot axis 115) laterally inclined at angle β (see...). Figure 8a It extends downwards, while extending inwards from the periphery of the arched wall 145 toward the pivot axis 115.

[0367] Figure 9a This is a front view schematic diagram of the tilt synchronization unit 140 of the steering mechanism 130, with the scooter 100 in the unfolded position, wherein the tilt synchronization unit 140 is operably paired with a pair of truncated rotating cones 142. Figure 9b This is a side elevation view of the tilt synchronization unit 140 of the scooter 100 in the unfolded position. The truncated rotating cone 142 has an inclination β relative to its central axis 113, such that when the tilted periphery of the truncated rotating cone 142 is operably placed against the corresponding tilted plane 144, the axis 113 is substantially perpendicular to the pivot axis 115.

[0368] Figure 10a This is a front-view stereoscopic diagram of the tilt synchronization unit 140 of the steering mechanism 130, illustrating the position of the scooter 100 at the instant of a left turn, as shown in the reference diagram. Figure 8a The tilt synchronization unit 140 includes a column interface portion 141 having a rotation axis that coincides with the pivot axis 115 of the steering column 110, a pivot receiving link component 146, and a synchronization body 143. Figure 10b This is a rear-view perspective view of the tilt synchronization unit 140 of the steering mechanism 130, showing the scooter 100 in a left-turn instantaneous position as an example.

[0369] The synchronizing body 143 includes, for example, two arched walls 145, wherein the arched walls 145 are part of an imaginary cylindrical thick wall 139 having a thickness W1 and an axis operatively coinciding with the pivot axis 115 of the steering column 110. The arched walls 145 are positioned at their base relative to an imaginary plane perpendicular to the pivot axis 115 at an angle α (see [reference needed]). Figure 8b It is diagonally truncated to form plane 144, including the right side 144. R And left side 144 LPlane 144 is also (relative to pivot axis 115) laterally inclined at an angle β (see...). Figure 10a It extends downwards, from the periphery of the arched wall 145 inwards toward the pivot axis 115.

[0370] Figure 11a This is a frontal perspective perspective view of the tilting unit 140 of the steering mechanism 130, showing, by way of example, the scooter 100 in a left-turn instantaneous position, wherein the tilting synchronization unit 140 is operatively paired with a pair of truncated rotating cones 142. Figure 11b This is a rear-view perspective perspective view of the tilt synchronization unit 140 of the scooter 100, illustrating by way of example the scooter 100 in a position at the instant of a left turn. The truncated rotating cone 142 has an inclination β relative to its central axis 113, such that when the inclined periphery of the truncated rotating cone 142 is operably placed against the corresponding inclined plane 144, the axis 113 of the truncated rotating cone 142 is substantially perpendicular to the pivot axis 115.

[0371] It should be understood that when the scooter 100 is in the unfolded position, the scooter 100 is in an idle state, including the balance actuator 148. It has an initial tension F. i The balancing actuators 148 are mutually balanced such that, at substantially the same corresponding position on plane 144, the truncated rotating cone 142 is adjacent to the corresponding inclined plane 144 at the center portion of the inclined plane 144, as... Figure 9a and Figure 9b The non-restrictive examples are shown in the text.

[0372] It should also be understood that when the scooter 100 is in a turning position, the pivoting front wheel (132) L 132 R ) Maintain an upright orientation, where both wheels remain firmly on the road when traveling at a reasonable speed. Additionally, the pivoting front wheel (132) L 132 R Each of these is configured to pivot about a corresponding independent axis with a turning radius of 158. (Return to reference) Figure 6a , Figure 6a The figure shows a front view of the scooter 100, where the scooter 100 is shown in a position at the moment of a left turn. It can be clearly seen that when the pivot frame element 188, together with the steering column 110, tilts to one side of the curve, the pivot frame element 188 tilts about the axis 185 of the non-pivot frame element 180, and the non-pivot frame element 180 remains tilted, approximately parallel to the ground. Therefore, the pivoting front wheel (132...) L 132 R ) Maintain an upright orientation, where both wheels remain firmly on the road when traveling at a reasonable speed. Additionally, the pivoting front wheel (132) L132 R Each of them is configured to pivot about its respective independent axis 158.

[0373] In order to bring the scooter 100 from an idle state into a position such as Figure 11a and Figure 11b In the example shown, with the desired instantaneous position for a left turn (a left turn is a non-limiting example of any desired direction for the driver), the driver of the scooter 100 typically pivots the steering column 110 to the left about the pivot axis 115 using one or both handlebars 116, while applying a pivoting force F. P The driver's pivoting motion triggers the following chain of reactions:

[0374] a. The steering column 110 overcomes the resistance F of the balance actuator 148. s Pivot to the left around pivot axis 115.

[0375] b. The tilt synchronization unit 140, which is securely attached to the steering column 110, pivots together with the steering column 110.

[0376] c. As the tilting synchronization unit 140 pivots, the tilting plane 144 also pivots, transferring the frictional force F F It is applied to the inclined periphery of the truncated rotating cone 142.

[0377] d. The corresponding fixed shaft 138 mounted on the non-pivoting frame element 180 (see Figure 7b and Figure 7c 138 R and 138 L ) on the truncated rotating cone 142 (142) R and 142 L It can rotate freely around the corresponding fixed axis 138, and the inclined plane 144 is on the freely rotating truncated rotating cone 142.

[0378] (142 R and 142 L It pivots while rolling on the inclined periphery of the ) . It should be understood that the inclined synchronization unit 140 and the truncated rotating cone 142 (142 R and 142 L ) and the corresponding fixed shaft 138 (138) R and 138 L The set of components, which can be called tilt synchronization components 155 (see [link]). Figure 7c ).

[0379] It should also be understood that due to the frictional force F between the two inclined surfaces F The inclined plane 144 rolls on the corresponding inclined periphery of the freely rotating truncated cone 142. It should also be understood that the frictional force F... FThis will cause abrasion on the surfaces of planes 144 and / or 142, which can be calibrated by a calibration mechanism (e.g., calibrating the attachment bolts of the corresponding fixed shaft 138, see...). Figure 7b and Figure 7c The calibration mechanism moves the inclined periphery of the freely rotating truncated cone 142 along the axis of rotation 113, while the inclined plane 144 remains stationary.

[0380] e. Due to the angle α of the inclined plane 144 (see...) Figure 8b When the corresponding plane 144 (right plane 144 in this example) R As it moves upward, an arched wall 145 moves upward (145 in this example). R ), and at the same time in the truncated rotating cone 142 R (In this example) the corresponding inclined perimeter rolls, and when the corresponding plane 144 (in this example, the left side 144) rolls. L As it moves downwards, another arched wall 145 either moves downwards or remains idle (in this example, 145). L ), and at the same time in the corresponding truncated rotating cone 142 L Scroll up.

[0381] As long as the driver keeps the pivot steering column 110 in place, the pivot steering column 110 will also tilt toward the selected turning side.

[0382] As the steering column 110 continues to tilt, a balance actuator 148 (in this example, the right balance actuator 148) R Increase its relative to the initial tension F i The tension, while another balance actuator 148 (in this example, the left balance actuator 148) L Reduce its relative to the initial tension F i Tension.

[0383] It should be understood that the balancing actuators 148 are unbalanced and tend to balance their tensions, that is, return them to their initial tension F. i The idle state. Therefore, once the driver reduces or releases the pivoting force, the balance actuator 148 pivots the steering column 110 toward a straight, upright position.

[0384] Preferably, the scooter 100 includes a folding mechanism that facilitates folding the scooter 100 into a folded state, such that the rear wheel 172 is positioned between or near the front wheels 132, wherein the rear wheel 172 is positioned above the front wheels 132, and wherein the scooter 100 can be carried as if it were personal luggage or a trolley rack. Figure 12aThis is a front perspective perspective view of a folded scooter 100 according to an embodiment of the present disclosure. The folded scooter 100 is shown in an upright position, which is the idle state of the scooter 100. Figure 12b This is a rear-view perspective view of the folded scooter 100, showing how the folding process is facilitated by unlocking the deck assembly 120 and a pair of interface profile arms 210 using the folding handle 200. It should be understood that the folded components can also be locked in the folded state. Figure 13a This is a front perspective perspective view of a folded scooter 100 in a folded state according to an embodiment of the present disclosure, wherein the scooter 100 may further include a utility toolbox 199 configured to be attached to a steering column 110, including in the folded state. Figure 13b Is it like this? Figure 13a The side view of the folded scooter 100 is shown.

In the example of the initial folding phase shown, the front end of the deck assembly 120 (which, without limitation, is generally parallel to the road surface) is shown as pivotally rising relative to the pivotally connected interface profile arm 210. Figure 14b This is a rear perspective view of the lower part of the scooter 100 according to an embodiment of the present disclosure, wherein the folding handle 200 has been raised to initiate the folding process. During folding, the interface profile arm 210 folds upward and pivots about axis 215, while the front end of the deck assembly 120 rises relative to the pivotally connected interface profile arm 210 and pivots about axis 125. While folding, the rear wheel 172 remains on the ground, but when folding is complete, the rear wheel 172 is in the air, allowing the scooter to be comfortably carried using the front wheel 132, similar to a trolley carrying rack.

[0386] Figure 15a This is a rear perspective view of the lower part of a scooter 100 according to an embodiment of the present disclosure, wherein the view shown is a close-up view of the locking / unlocking mechanism that facilitates the folding process of the scooter 100. The main folding components of the scooter 100 are the deck assembly 120 and the interface profile arm 210, which are pivotally connected to each other.

Figure 14a and Figure 14b As described, pulling the folding handle 200 upwards along direction 205 initiates the folding process. When the folding handle 200 is pulled along direction 205, the traction cable 252 is pulled along direction 255 on each side of the scooter 100, as the traction cable 252 is securely attached to the folding handle 200. Typically, the traction cable 252 and other traction cables connected to each traction cable 252 are segmented in a protective sleeve (250s, see...). Figure 16b ). Figure 15c The figure illustrates as follows Figure 15a The lower part of the scooter 100 shown has the stand 121 removed for illustration purposes only.

Locking pin unit 242 is also shown. Figure 16c As shown, the locking pin unit 242 includes a main elongated body 244, a locking end 246, and a pull-out end 245. The locking end 246 is shown located within an external fixing cavity 236 and locked therein. The pull-out end 245 is configured to securely receive the end of a corresponding cable segment 250. The cable segment 250 is shown covered by a protective sleeve 250s. Figure 16c In the non-limiting example shown, the end of cable segment 250 is inserted into a hole 241 formed at the center of the end of the pulled end 245, and a fastening screw (not shown) secures the end of cable segment 250 to locking pin unit 242 via a corresponding thread 243.

The locking pin housing 248 may also include a biasing element, such as a spring 249 or any other type of biasing element.

[0392] When the folding handle 200 is pulled along direction 205, the traction cable 252 is pulled backward toward the folding handle 200. When the traction cable 252 is pulled, the cable segment 250 is pulled, causing the corresponding pulled end 245 of the corresponding locking pin unit 242 to be pulled into the corresponding locking pin housing 248 and resist the corresponding biasing element 249.

When the scooter 100 is in the folded state, one or more first magnets 320 and corresponding one or more complementary magnets 310 are pre-configured to be positioned adjacent to each other, so that the folded scooter 100 is held in the folded state by the resulting interacting magnetic forces.

[0397] Figure 22 The schematic diagram illustrates a second non-limiting example embodiment of a scooter 500 according to some aspects of this disclosure. The scooter 500 includes a steering column 510, a deck assembly 520 having a stand-up plate 521 and a rear wheel assembly 570, a steering mechanism 530, and an optional removable bag 599, wherein the steering column 510 is in a straight, upright position. The stand-up plate 521 is configured to tilt to one side toward the inner periphery of a turning curve and is configured to support a rider who typically stands on it.

[0398] The steering column 510 may include a handlebar 518 with two handlebars 516, assisting the rider of the scooter 500 in turning left or right by pivoting the steering column 510 accordingly. A primary aspect of this disclosure is to provide a mechanism in which, when the steering column 510 is pivoted, it is also forced to tilt to one side toward the inner periphery of the turning curve. Typically, the pivot axis 515 of the steering column 510 is operatively located on the longitudinal axis 505 of the scooter 500.

[0399] Therefore, the steering mechanism 530 allows the rider to turn the steering column 510 as desired to turn the scooter 500 to the left or right. Figure 23 The schematic diagram shows a scooter 500 according to various embodiments of the present disclosure in a state where the steering column 510 is pivoted to the left along direction 517 and thus also tilts to the left. Figure 24 This is a rear-view perspective view of a scooter 500 according to several embodiments of the present disclosure, wherein the steering column 510 pivots to the left and therefore also tilts to the left. Tilt measurement is indicated at a constant pre-configured rate. In one embodiment, the steering column 510 is subdivided into an upper column 512 and a lower column 514, wherein the upper column 512 slides retractably on the lower column 514.

[0400] Steering mechanism 530 also includes a pair of front wheels 532 interconnected to steering column 510 via the steering mechanism, wherein when steering column 510 pivots, the front wheels (532) L 532 R Each of them also pivots in the same direction via wheel pivoting mechanism 550, such as Figure 25 As shown. Figure 25 This is a top perspective perspective view of the front portion of a scooter 500 according to several embodiments of the present disclosure, wherein a non-limiting example of the wheel pivoting mechanism 550 is shown based on the Ackermann steering principle. In such an ASP steering mechanism, the inner front wheel needs to turn at a different angle than the outer wheel because they turn at different radii. The ASP steering mechanism is the geometric arrangement of the link components (e.g., 567, 552, 554, 556) in the wheel pivoting mechanism 550, which is designed to turn the inner and outer wheels at appropriate angles. Any other mechanism known in the art for coordinating the pivoting of two front wheels, such as in a car (but not, for example, in a "carriage" mechanism), can be used. An exemplary wheel pivoting mechanism 550 includes a pivot receiving link component 556 that receives pivoting motion from a steering column 510, which is transmitted to the front wheel 532 via a pair of axially moving links 552 and 554. L and 532 R This is transmitted to the corresponding linkage component 556, to which the corresponding front wheel 532 is rotatably attached. It should be understood that when the scooter 500 is in a turning position, the pivoting front wheel (532)...L 532 R Maintaining an upright orientation, where both wheels remain firmly on the road when traveling at a reasonable speed. Individual linkage components 556 (556) L 556 R It also includes the corresponding independent axis 558 (558) L 558 R When turning, the corresponding front wheel (532) L 532 R It pivots around the corresponding axis 558.

[0401] Rear wheel assembly 570 (see example) Figure 22 , Figure 23 and Figure 25 The rear wheel assembly 570 includes a rear wheel 572 rotatably connected to the rear axle. The rear wheel assembly 570 may also include a rear wheel cover 574. The rear wheel assembly 570 can be operated by a rear wheel motor, which, without limitation, may be powered by, for example, a battery 999 (see example...). Figure 26b , Figure 36c The electric motor (not shown) provides power. The rear wheel cover 574 may also serve as a braking mechanism or part thereof. It should be understood that the wheel motor can be configured to drive the scooter device forward or backward, or both forward and backward.

[0402] Figure 26a This is a partial front view of the scooter 500, schematically illustrating a non-limiting example of the steering mechanism 530, where some parts (related to the steering column 510) have been removed for illustrative purposes only, and the scooter 500 is shown in the deployed position (state). Similarly, Figure 27a This is a front view of the scooter 500, schematically illustrating the steering mechanism 530, where some obscured portions have been removed for illustrative purposes only, and where the scooter 500 is shown in a position at the moment of a left turn.

[0403] Figure 26b This is a front view schematic diagram of the steering mechanism 530 of the scooter 500 shown in the unfolded position. Figure 26b The diagram illustrates the components that facilitate the scooter's left or right turns. Similarly, Figure 27b This is a front view schematic diagram of the steering mechanism 530 of the scooter 500, shown as being in a position of instantaneous left turn. Figure 27b The diagram illustrates participation in promoting scooter 500 turns (in...) Figure 27b The non-restrictive example shown is a component for turning left.

[0404] The steering mechanism 530, which utilizes the automatic tilting of the steering column 510 to facilitate the turning of the scooter 500, includes a steering column 510, a pair of front wheels 532, a tilt synchronization unit 540, and a pair of balance actuators 592. UP 592 LW (Seen as a pair of springs only, for example only). The balance actuator 592 can also be implemented as, for example, a pair of pneumatic or hydraulic mechanisms. The steering mechanism 530 also includes the following interface components: pivot interface unit 560, tilt conveyor unit 590, and non-pivot frame element 580.

[0405] It should be understood that when the rider pivots the steering column 510, the pivot interface unit 560, which is firmly attached to the steering column 510, pivots together with the steering column 510, while the tilting delivery unit 590, which is pivotally connected to the non-pivoting frame element 580 at the bearing 585, tilts to one side in sync with the pivoting movement of the steering column 510.

[0406] This pair of similar balance actuators 592 (592 UP 592 LW ) Installed on a common vertical support rod 595 (see example) Figure 26a ), including a pair of end stops (upper end stop 591) UP and lower end stop 591 LW Limiting the balance actuator (592) UP 592 LW The movement of the balancing actuator (592) UP 592 LW End stops (591) arranged on vertical support rod 595 UP 591 LW Between them, the vertical support rod 595 has an upper open end and a lower open end (see example). Figure 27a and Figure 27b When the balance actuator (592) UP 592 LW Balanced actuator (592) UP 592 LW When an external force is applied (or extended), the external force is stored internally, where the balancing actuator (592) is located. UP 592 LW The stored force is used to attempt to return to its idle state. Balance actuator 592 UP and 592 LW Separated by a force-transmitting ring 594 arranged therebetween, wherein the force-transmitting ring 594 receives from the inclined conveying unit 590 along the vertical support rod 595 and toward the balancing actuator 592. UP Or 592 LWThe force transmission vector, the tilting transmission unit 590 is securely attached to the steering column 510 and configured to pivot about a bearing 585 located at the lateral center of the non-pivoting frame element 580. When no tilt is applied to the steering column 510, the force transmission ring 594 applies equal pressure to the two balancing actuators 592 (592 UP 592 LW )superior.

[0407] It should be understood that the upper end stop 591 UP and lower end stop 591 LW The corresponding position can be, for example, by the corresponding nut 593 UP Or 593 LW To adjust (see example) Figure 27a and Figure 27b ).

[0408] The force conveying ring 594 is securely and operably connected to the inclined conveying unit 590. Therefore, the force conveying ring 594 actuates the non-pivoting frame element 580 and the corresponding balancing actuator 592. UP and / or 592 LW The relative rotational driving force between the steering column 510 and the steering column 592 applies a steering column return force in the opposite direction to the pivoting force applied to the steering column 510 by the driver. Once the driver reduces or releases the pivoting force (or turns the steering column 510 back), the balance actuator 592 applies a counterforce to the force delivery ring 594, which causes the steering column 510 to pivot toward a straight, upright position. It should be understood that the balance actuator 592 can store bias force by compressing the compressible balance actuator 592 or by pulling the balance actuator 592. This disclosure is described as if the corresponding balance actuator 592 is compressed, and the bias force stored in the corresponding balance actuator 592 attempts to return to its idle, uncompressed state (or balance actuator 592). UP and balance actuator 592 LW The equilibrium compression state between the two.

[0409] It should also be understood that the standing plate 521, which is also attached to the tilting conveyor unit 590, is configured to tilt to one side toward the inner periphery of the curve, together with the tilting conveyor unit 590 (see, for example, see...). Figure 27a and Figure 27b And for example, in the following Figure 28a The scooter folding interface assembly 600 shown is illustrated.

[0410] supply Figure 28a and Figure 28b To further clarify the interrelationship between the steering mechanism 530 and the pivot interface unit 560, tilt synchronization unit 540, tilt conveying unit 590 and non-pivot frame element 580. Figure 28a This is a rear-view perspective view of the steering mechanism 530 component when the scooter 500 is in the instant of a left turn. Figure 28b This is a frontal elevation perspective view. When the steering column 510 is pivoted (to the left in the non-limiting example shown), the tilt synchronization unit 540 and the truncated rotating cone 542 together facilitate the automatic tilting of the steering column 510.

[0411] The non-pivotable frame element 580 includes a tilt sync unit retaining ring 582 configured to secure the tilt sync unit 540 to the non-pivotable frame element 580. On the other hand, the pivot interface unit 560 is secured to the steering column 510 such that when the steering column 510 is pivoted by the rider or otherwise, the pivot interface unit 560 pivots together with the steering column 510. Figure 28c This is a rear vertical cross-sectional view of a part of the steering mechanism 530 component, in which the steering column 510 is in an upright position.

[0412] Also referenced Figure 29a and Figure 29b , Figure 29a The figure shows a front-view perspective view of the tilting synchronization unit 540, and Figure 29b The figure shows a front-view perspective view of the tilt synchronization unit 540. The tilt synchronization unit 540 includes two parallel arched deep ribs: a top arched rib 544 and a bottom arched rib 546. See also... Figure 29c The figure shows a side view of the tilting synchronization unit 540, facing the top arched rib 544 and the bottom arched rib 546. Each arched rib (544 and 546) has a corresponding inner plane (543 and 547) that slopes laterally inward, wherein the inner arched gap D... in Compared to the external arched gap D ext It is wide and remains operable even along the full operating length of the two arched ribs (544 and 546).

[0413] It should be understood that when the steering column 510 is in the upright position, a pair of arched ribs (544 and 546) have an initial tilt angle relative to the horizon.

[0414] Also refer to Figure 29dThe figure shows a front vertical section view of the tilting synchronization unit 540, in which a truncated rotating cone 542 is arranged between a top arched rib 544 and a bottom arched rib 546. The tilted periphery 548 of the truncated rotating cone 542 and the periphery of the inner planes (543 and 547) operably have the same angle γ, such that the truncated rotating cone 542 can freely and adaptively roll from one end of the inner plane (543 or 547) of the corresponding arched rib (544 and 546) to the other end of the inner plane (543 or 547) of the corresponding arched rib (544 and 546) within the internal space formed between the inner planes (543 and 547).

[0415] Also refer to Figure 29e The figure shows a frontal transverse cross-sectional view of the tilt synchronization unit 540. Figure 29f The figure shows Figure 29e The top view of the section shown shows the arched inner plane 547 of the arched rib 546 fully displayed, and the arched rib 546 (also implying arched rib 544) is shown as part of a hypothetical cylindrical ring 539 having a depth W2 and a lateral axis that operatively coincides with the pivot axis 515 of the steering column 510.

[0416] It should be understood that when the steering column 510 is in the upright position, the truncated rotating cone 542 is arranged between the top arch rib 544 and the bottom arch rib 546, at (or near) the center of the inner plane (543 and 547). Figure 30a The figure shows a top perspective view of the tilting synchronization unit 540, in which the truncated rotating cone 542 is arranged between the top arched rib 544 and the bottom arched rib 546, at the center of the inner plane (543 and 547). Figure 30b The figure shows Figure 30a A bottom-view perspective view of the tilt synchronization unit 540 shown. Also referenced is... Figure 30c , Figure 30c The figure shows a top perspective view of the tilting synchronization unit 540, in which the truncated rotating cone 542 is arranged between the top arched rib 544 and the bottom arched rib 546, near the front end of the inner plane (543 and 547), showing the instantaneous position of the left turn. Figure 30d The figure shows Figure 30c The tilt synchronization unit 540 shown is viewed from below.

[0417] Also referenced Figure 31a , Figure 31aThis is a front elevation perspective view of the pivot interface unit 560 according to the present disclosure. The pivot interface unit 560 includes a column interface portion 564 having a rotation axis coinciding with the pivot axis 515 of the steering column 510, a pivot receiving link arm 566, a pivot receiving link assembly 567, a rotating cone link arm 562, and a rotating cone link assembly 561. The rotating cone link assembly 561 includes a fixed shaft 531, wherein the truncated rotating cone 542 is rotatably mounted on the fixed shaft 531, such as... Figure 31b As shown. The pivot receiving link arm 566 is securely attached to the pivot interface unit 560, as... Figure 28b As shown.

[0418] Figure 32a This is a slightly elevated perspective view of the tilt synchronization unit 540 of the steering mechanism 530, with the scooter 500 in the deployed position, the steering column 510 in an upright position, and the tilt synchronization unit 540 operablely paired with a truncated rotating cone 542, which is rotatably mounted on the rotating cone link assembly 561, the rotating cone link arm 562, and the fixed shaft 531 of the pivot interface unit 560. It should be understood that, since the steering column 510 is in an upright position, the truncated rotating cone 542 is arranged between the top arched rib 544 and the bottom arched rib 546 at (or near) the center of the inner planes (543 and 547).

[0419] Figure 32b This is a forward-looking perspective view of the tilt synchronization assembly 555, which includes a tilt synchronization unit 540 of the steering mechanism 530. The scooter 500 is in the deployed position, where, as an example, the scooter 500 is shown in a position of instantaneous left turn. The tilt synchronization unit 540 is operatively paired with a truncated rotating cone 542, which is rotatably mounted on a fixed shaft 531 of the rotating cone link assembly 561, the rotating cone link arm 562, and the pivot interface unit 560. It should be understood that, since the steering column 510 is pivoted to the left in this example, the truncated rotating cone 542, positioned between the top arched rib 544 and the bottom arched rib 546 near the front end of the inner planes (543 and 547), shows the position of instantaneous left turn. When the rider pivots the steering column 510 to the left, the truncated rotating cone 542, arranged between the top arch rib 544 and the bottom arch rib 546, rolls proportionally to the pivot angle at its front end toward the inner plane (543 and 547) between the arch ribs 544 and 546.

[0420] It should be understood that when a right turn is made (in this example embodiment), the truncated rotating cone 542 rolls toward the rear end of the inner plane (543 and 547) between the arched ribs 544 and 546 by pivoting the steering column 510 to the right.

[0421] The tilt synchronization unit 540 of the steering mechanism 530 may also include a tilt biasing mechanism for the steering column 510, which, in addition to the degree of pivoting of the steering column 510, is based on the drive speed of the scooter 500. A speed biasing motor 549 is pivotally attached to the tilt synchronization unit 540 via a central shaft 541, the rotation axis 545 of which (see, for example) Figure 29d and Figure 29e It coincides with the rotation axis of the speed bias motor 549.

[0422] Typically, without restrictions, the tilt angle is preset to a balanced (no bias) state pre-designed for a certain average riding speed. If the current speed is higher than that average riding speed, the speed bias motor 549 can be activated to pivot the tilt synchronization unit 540, thereby increasing the tilt angle of the arch ribs (544 and 546) and the tilt angle of the steering column 510; and if the current speed is lower than that average riding speed, the speed bias motor 549 can be activated to pivot the tilt synchronization unit 540, thereby decreasing the tilt angle of the arch ribs (544 and 546) and the tilt angle of the steering column 510.

[0423] It should be understood that when the scooter 500 is in the unfolded position, the scooter 500 is in an idle state, including the balance actuator 592. It has an initial tension F. j The balancing actuators 592 are mutually balanced, such that the rotating cone 542 is located near the inclined inner planes (543 and 547), at the center portion of the inclined planes (543 and 547), as... Figure 29a , Figure 29f , Figure 30a and Figure 30c The non-restrictive examples are shown in the figure.

[0424] It should also be understood that when the scooter 500 is in a turning position, the pivoting front wheel (532) L 532 R ) Maintain an upright orientation, where both wheels remain firmly on the road when traveling at a reasonable speed. Additionally, the pivoting front wheel (532) L 532 R Each of these is configured to pivot about its respective independent axis 558. (Return to reference) Figure 27a , Figure 27a The figure shows a front view of the scooter 500, which is shown in a position at the moment of a left turn. It can be clearly seen that while the pivot interface unit 560 tilts to one side of the curve along with the steering column 510, the pivot interface unit 560 tilts about the axis 585 of the non-pivoting frame element 580, and the non-pivoting frame element 580 remains flat and approximately parallel to the ground. Therefore, the pivoting front wheel (532)...L 532 R ) Maintain an upright orientation, where both wheels remain firmly on the road when traveling at a reasonable speed. Additionally, the pivoting front wheel (532) L 532 R Each of these is configured to pivot about its respective independent axis 558 (see [link]). Figure 25 ).

[0425] To enable the scooter 500 to transition from an idle state to the desired left-turn instantaneous position, such as... Figure 22 and Figure 23 As shown in the example (left turn is a non-restrictive example of any desired direction by the driver), the pivoting force F is typically applied by using one or both levers 516. p Simultaneously, the rider of the scooter 500 pivots the steering column 510 to the left around the pivot axis 515. The rider's pivoting action triggers the following chain of reactions:

[0426] a. The steering column 510 pivots to the left around the pivot axis 515, overcoming the resistance Fs of the balance actuator 592.

[0427] b. Securely attached to the steering column 510, the tilt synchronization unit 540 pivots together with the steering column 510.

[0428] c. When the tilting synchronization unit 540 pivots, the inner planes (543 and 547) of the arched ribs (544 and 546 respectively) also pivot, transferring the frictional force F F It is applied to the inclined periphery 548 of the truncated rotating cone 542.

[0429] d. Frustum rotary cone 542 mounted on fixed shaft 531 (see Figure 31a and Figure 31b It can rotate freely about a fixed axis 531, while the inner planes (543 and 547) roll on the inclined periphery of the freely rotating truncated rotating cone 542, wherein the fixed axis 531 is fixed on the rotating cone link arm 562 of the pivot interface unit 560.

[0430] It should be understood that the assembly of the tilt synchronization unit 540, the truncated rotary cone 542, and the pivot interface unit 560 can be referred to as the tilt synchronization assembly 555 (see [link to documentation]). Figure 26b , Figure 27b , Figure 28b , Figure 32a and Figure 32b ).

[0431] It should also be understood that due to the frictional force F between the two inclined surfaces... pThe inclined inner planes (543 and 547) roll on the inclined periphery of the freely rotating truncated cone of revolution 542. It should also be understood that the frictional force F... F This can cause abrasion on the surfaces of the inclined inner planes (543 and / or 547), which can be mitigated by a calibration mechanism (e.g., calibration bolt 538, see...). Figure 31b The calibration mechanism moves the inclined periphery of the freely rotating truncated cone 542 along the axis of rotation 565 while the inclined inner planes (543 and 547) remain stationary.

[0432] e. The pivot interface unit 560, securely attached to the steering column 510, pivots together with the steering column 510 about the pivot axis 515 of the steering column 510. The pivot interface unit 560 is also securely attached to the tilting conveyor unit 590, which is pivotally connected to the non-pivoting frame element 580 at the bearing 585. Therefore, when the pivot interface unit 560 pivots about the pivot axis 515 of the steering column 510, the pivoting motion of the pivot interface unit 560 is also converted by the tilting conveyor unit 590 into the tilting motion of the tilting conveyor unit 590, and the tilting motion of the pivot interface unit 560 and the steering column 510 (with respect to the bearing 585).

[0433] Therefore, the steering column 510 tilts to one side synchronously with its pivoting movement, and as long as the driver maintains the pivoting steering column 510, it also tilts to the selected pivoting movement side. As the steering column 510 continues to tilt, a balance actuator 592 (in this example, the right balance actuator 592)... LW (relative to the initial tension F) j Increase its tension, while another balance actuator 592 (in this example, the left balance actuator 592) increases its tension. UP (relative to the initial tension F) j Reduce its tension.

[0434] It should be understood that during the tilting of the steering column 510, the unbalanced balancing actuators 592 attempt to balance their tensions and return them to their initial tension of F. j The idle state. Therefore, once the driver reduces or releases the pivoting force applied to the steering column 510, the balance actuator 592 pivots the steering column 510 toward a straight, upright position.

[0435] Preferably, the scooter 500 includes a folding mechanism that facilitates folding the scooter 500 into a folded state, such that the rear wheel 572 is positioned between or near the front wheels 532, wherein the rear wheel 572 is positioned above the front wheels 532, and wherein the scooter 500 can be carried as if it were personal luggage or a trolley rack.

[0436] Figure 33a This is a front perspective view of a folded scooter 500 according to an embodiment of the present disclosure, with the scooter in a folded state. The folded scooter 500 is shown in an upright position, which is the idle state of the scooter 500. Figure 33b This is a rear perspective view of the folded scooter 500, showing the interface profile arm 610 of the scooter folding interface assembly 600 (e.g., as described below). Figure 34a The folding process is facilitated after the locking mechanism (shown in the diagram) is unlocked. It should be understood that the folding component can also be locked in the folded state. It should be understood that, according to embodiments of this disclosure, the scooter 500 may also include a utility toolbox 599 configured to be attached to the steering column 510, including in the folded state.

[0437] Figure 34a This is a rear perspective elevation view of the lower part of a scooter 500 according to an embodiment of the present disclosure. During the folding process when the scooter folding interface assembly 600 is activated, the interface profile arm 610 folds upward and pivots about axis 615, while the front end of the deck assembly 520 rises relative to the pivotally connected interface profile arm 610 about axis 625 (e.g., below). Figure 34c (As shown below) Pivoting. When folded, the rear wheel 572 remains on the ground, but when folded, the rear wheel 572 is in the air, facilitating comfortable use of the front wheel 532 to park the scooter or carry the scooter as a trolley rack. The lower rear end of the interface profile arm 610 is pivotally connected to the lower rear pivot joint (see below, for example). Figure 34c , Figure 34d , Figure 35a , Figure 35b and Figure 36a 620 RR The lower rear pivot joint is securely attached to the panel assembly 520, facilitating pivoting movement between the interface profile arm 610 and the panel assembly 520. It should be noted that the upper front end of the interface profile arm 610 is pivotally attached to the upper front rotary joint (see below, for example...). Figure 34e , Figure 35a and Figure 36a 620 FR It is securely attached to the inclined conveyor unit 590, facilitating pivoting movement between the interface profile arm 610 and the steering mechanism 530.

In the illustrated state, the front end of the deck assembly 520 (typically parallel to the road surface where there are no restrictions) is connected to the forward tilting conveyor unit 590 (see also...) via an interface profile arm 610. Figure 28a The interconnections facilitate the tilting of the board assembly 520 while the scooter 500 is in the unfolded position.

[0444] For example, Figure 22 The illustration shows a scooter 500 in its unfolded position, where, typically, the rear lower locking mechanism 630 is in the unfolded position. RR Preferably in a locked state (see) Figure 34c ), of which the lower rear latch threaded bolt 638 RR Locked in the unfolded rear receiving threaded cavity 621 RR In the middle; and the front locking mechanism 630 FR Preferably in the locked state, wherein the front upper latch threaded bolt 638 FR Locked in the unfolded front receiving threaded cavity 621 FR middle.

[0445] Without restrictions, the folding mechanism of the scooter 500 can preferably be fully automatic. See also... Figure 36a The illustration shows a scooter folding interface assembly 600, in which the scooter 500 is in the unfolded position and includes a folding motor 640. Figure 36b The figure shows Figure 36a The scooter folding interface assembly 600 shown has the folding motor 640 removed for the purposes illustrated.

[0446] Scooter 500 from unfolded position (see Figure 22 ) to folded state (see Figure 33c The transition from the folded position to the unfolded position typically involves two basic movements: 1) a movement of the scooter folding interface assembly 600 toward and back towards the steering column 510; and 2) a movement of the deck assembly 520 toward and back towards the scooter folding interface assembly 600. The paths executed by these two components simultaneously are neither the same nor equal: the movement of the deck assembly 520 toward and back towards the scooter folding interface assembly 600 is longer than the movement executed by the scooter folding interface assembly 600. The method for transitioning the scooter 500 from the unfolded position to the folded position and from the folded position to the unfolded position is configured to synchronize the movements of these two components.

[0447] The folding and unfolding mechanism of the scooter 500 described in this disclosure also includes an upper front pivot joint 620. FR Lower rear pivot joint 620 RR A non-elastic tensioned cable (or tape) 650, which is wound around a pair of reels: (see example) Figure 36a and Figure 36bThe rear spool 654 is pivoted. The tension cable 650 is anchored to the front spool 652 via the front anchoring element 651 and to the rear spool 654 via the lower anchoring element 653. Each pivot joint 620 (620...) FR 620 RR ) includes shaft retaining hinge device 628 (628) FR 628 RR ) and ring (or bearing) element 624 (624 FR 624 RR It should be understood that the tension cable 650 can be replaced by a timing belt or a chain connected to a pair of gears.

[0448] Figure 36c This is a rear-view perspective view showing the interconnectivity of the scooter folding interface assembly 600 and other units of the scooter 500 according to the present invention. Figure 36d It is the lower rear pivot joint 620 RR The rear cross section diagram DD' (see) Figure 36a ), including the lower rear pivot joint 620 RR Including rear axle retaining hinge device 628 RR and the ring element 624 RR . Figure 36e It is a pivot retaining hinge device 628 RR A three-dimensional diagram. Shaft-holding hinge device 628 RR Including attachment body 626 RR The attachment body 626 RR Configured to use the rear connector interface element 634 RR Securely attached to the lower rear end of the interface profile arm 610. Rear connector interface element 634 RR It is also configured to accommodate the rear latch threaded bolt 638. RR and fixed drive sleeve 632 RR (See example) Figure 36a , Figure 36b Shaft-holding hinge device 628 RR It also includes a pair of rear hinge walls (627) RR and 629 RR ), of which the rear hinge shaft 623 RR Fixed between them. Similarly, the front axle retaining hinge device 628 FR Including attachment body 626 FR The attachment body 626 FR Configured to use front connector interface element 634 FR Securely attached to the upper front end of the interface profile arm 610. Front connector interface element 634 FR It is also configured to accommodate the upper front latch threaded bolt 638 FRand fixed drive sleeve 632 FR (See example) Figure 36a , Figure 36b Shaft-holding hinge device 628 F R also includes a pair of front hinge walls (627) FR and 629 FR ), of which the front hinge shaft 623 FR Fixed between them.

[0449] Because the scooter folding interface assembly 600 and the deck assembly 520 are not of equal diameter when folding or unfolding, the diameter of the rear wheel 654 is smaller than that of the front wheel 652 by a certain proportion. This proportion allows the scooter folding interface assembly 600 and the deck assembly 520 to achieve a pre-constructed state of simultaneous stillness.

[0450] The tension cable 650 is stretched between the pivoting rear reel 654 and the fixed front reel 652, establishing a tension τ. The tension cable 650 is anchored to both reels, ensuring that it is not sliding on either reel (652, 654) but rather wound around it. When the scooter 500 is folded or unfolded, the two moving elements (scooter folding interface assembly 600 toward or away from the steering column 510) simultaneously begin and complete their respective movements because the inelastic tension cable 650 remains stretched.

[0451] According to variations of this disclosure, the internal locking mechanism can be implemented using various locking / unlocking mechanisms known in the art. Another locking / unlocking mechanism for the interface profile arm 610 is described below. (Referring now to...) Figures 37a-37c . Figure 37a This is a side vertical cross-sectional schematic diagram of the interface profile arm 611 according to some non-limiting example embodiments of the present disclosure. The interface profile arm 611 includes a lower rear locking pin mechanism 670 of the steering column 510. RR Similar to the front-locking mechanism 670 FR Both are shown as being in the unlocked state, with the corresponding latch bolt (678) RR (For panel locking pin), 678 FR (The locking pin) is in the unlocked position. Figure 37a In the example state shown, the deployed receiving cavity (661) RR 661 FR ) is shown as facing the latch bolt (678) RR 678 FR The corresponding locking end (671) RR 671 FR The end of the folded receiving cavity (662)RR 662 FR ) is shown as being away from the corresponding latch bolt (678) RR 678 FR Locking end (671) RR 671 FR ) is adapted to be housed in the corresponding locking pin housing (672) RR 672 FR Within, guide the corresponding locking end (671) RR 671 FR ) enters and exits the corresponding receiving cavity (662) RR 662 FR ).

[0452] Figure 37b This is a side view schematic diagram of the internal components of the interface profile arm 611 according to some non-limiting example embodiments of the present disclosure, wherein the interface profile 611 has been removed for illustrative purposes only. Figure 37b As shown, the lower motor 675 RR and the upper motor 675 FR These are all corresponding motor gear assemblies (676) RR 676 FR These components may also include corresponding gears (677) as part of the overall structure.

Figure 38d This is a side view of the scooter 500 at the moment of its fold in the middle; Figure 38e This is a rear-view 3D illustration of the 500 scooter in its folded state; and Figure 38f This is a front-view stereoscopic illustration of the 500 scooter in a folded state.

[0456] Without restrictions, the folding mechanism of the scooter 500 can be fully automatic. See also... Figure 36a It shows a scooter folding interface assembly 600, in which the scooter 500 is in the unfolded position, including a folding motor 640. Figure 36b The figure shows Figure 36a The scooter folding interface assembly 600 shown has the folding motor 640 removed for illustrative purposes only.

[0457] It should be understood that although the folding motor 640 is shown as being attached to the panel assembly 520, the folding motor 640 can be fixed to other locations along the tension cable 650.

[0458] It should also be understood that the folding of a scooter can be fully manual or partially manual, as will be further described below.

[0459] Figure 39aThis is a front perspective perspective view of the interface between the rear pulley 654 and the folding motor 640 according to some non-limiting example embodiments of the present disclosure, wherein the folding motor 640 is configured to drive the pivot pulley 654 via the rear wheel axle 645, thereby winding or unwinding a portion of the tension cable 650 onto or from the rear pulley 654. Figure 39b This is a partial cross-sectional perspective view of the interface between the rear pulley 654 and the folding motor 640, in which various components have been removed for illustrative purposes only. Figure 39c It is the lower rear pivot joint 620 RR A three-dimensional view of the rear facade of the interface, including the folding motor 640.

[0460] By using the lower latch threaded bolt 638 RR Drive away from the selected receiving thread cavity (the lower expanded receiving thread cavity 621) RR Or folded receiving threaded cavity 622 RR And drive the front latch threaded bolt 638 FR Leaving the selected receiving threaded cavity (front-expanded front receiving threaded cavity 621) FR Or folded front receiving threaded cavity 622 FR After unlocking the scooter folding interface assembly 600, an automatic folding / unfolding process can be initiated. For example, in the unfolded position, the lower rear latch threaded bolt 638... RR Driven away from the lower unfolded rear receiving threaded cavity 621 RR And the front latch bolt 638 FR Driven away from the front receiving threaded cavity 621 that has expanded at the front FR Then, the automatic folding / unfolding process can be initiated by activating the folding motor 640.

[0461] As described above, the folding motor 640 is configured to power the pivot spool 654 via the rear axle 645, which is fixed to the rear axle 645. This is due to the rear pivot joint 620. RR and front pivot joint 620 FR It has been unlocked, therefore the ring element 624 RR Relative to shaft retaining element 628 RR The rear spool 654 pivots freely about axis 655. Therefore, once the folding motor 640 is activated, the rear spool 654 pivots and the tension cable 650, anchored to the rear spool 654, begins to wind around it, thus applying tension to the tension cable 650. The tension generated by the tension cable 650 is transmitted to the lower rear pivot joint 620. RR And due to the rear annular element 624 RR It can be relative to the shaft retaining element 628 RR Free pivoting, and the front annular element 624 FRIt can be relative to the shaft retaining element 628 FR It can pivot freely about axis 656. The front annular element 624 is fixed to the inclined conveyor unit 590. FR Remains in place, while being fixed to the front hinge wall (627) FR and 629 FR ,See Figure 36a The front end of the interface profile arm 610 is connected to the front hinge shaft 623. FR Pivot to front annular element 624 FR Inside.

[0462] Thus, the folding process begins: fixed to the rear annular element 624. RR The front end of the standing plate 521, together with the rear end of the interface profile arm 610, begins to tilt upward and forward toward the steering column 510 (see...). Figure 36a , Figure 36b Path curve 618).

[0463] The rear wheel cover 574 of the scooter 500 can also be used as a stand. Figure 40a An exemplary rear wheel cover 574 is illustrated in a slightly elevated perspective view. Figure 40b This is a side view illustration of example rear wheel cover 574. Now refer to... Figure 40c The scooter 500 is shown in a side view, where it is shown at the instant just before the folding process is completed, and where the rear wheel 572 is still on the road surface of the road 50. See also... Figure 40d ,in Figure 40c The scooter 500 shown has just reached the end of the folding process, and the rear wheel 572 is preferably in the air, above the ground plane, and the scooter 500 is tilted back on the rear wheel cover 574, which now serves as a support.

[0464] It should be understood that because the scooter 500 includes at least two front wheels 532, it is able to stand still without any support. This also facilitates the autonomous movement of the scooter 500. The scooter 500 can be equipped with sensors, without limitations, such as cameras, GPS, controllers, and devices for remote communication, enabling operation via remote communication.

[0465] Now refer to Figure 41a The image shows elements of a non-limiting example embodiment of an autonomous driving mechanism 680, which includes an automatic motor 682 disposed in an upper column 512 of a steering column 510, a rotary drive rod 684, and a rotary receiving rod 686 fixed to a lower column 514, wherein the rotary drive rod 684 and the rotary receiving rod 686 are operably disengaged. Figure 41b yes Figure 41aThe diagram shows a rear-view cross-section of the autonomous driving mechanism 680. Figure 41c This is a rear view of the automatic driving mechanism 680, in which the rotary drive rod 684 and the rotary receiver rod 686 are operatively engaged. Figure 41d yes Figure 41c The diagram shows a rear-view cross-section of the autonomous driving mechanism 680.

[0466] Therefore, in this example embodiment, to activate the drive mechanism 680, the upper column 512 moves downward on (or inside) the lower column 514 until, for example, the tip 685 of the lower end of the rotary drive rod 684 is fixed within the receiving opening formed at the upper end of the rotary receiving rod 686, at which point the rotary drive rod 684 engages with the rotary receiving rod 686. Then, when the automatic motor 682 is activated, the rotary drive rod 684, which is rotatably connected to the rotary drive rod 684, begins to pivot in a selected direction; the rotary receiving rod 686, fixed to the rotary drive rod 684, pivots together with the rotary drive rod 684. Since the rotary receiving rod 686 is fixed to the lower column 514, the steering column 510 pivots together with the rotary receiving rod 686. To disengage from automatic driving, the drive unit can simply lift the upper column 512.

[0467] It should be understood that by using sensors (without limitations, such as camera units and GPS) and by remotely controlling the scooter motor connected to the rear wheel 572, the scooter 500 can be remotely driven in any direction, transport goods, engage with a battery charging device, and perform a variety of other tasks.

[0468] According to variations of this disclosure, Figure 42a and Figure 42b The schematic diagram illustrates a third non-limiting example embodiment of scooters 700 and 701 according to the present disclosure, which includes a steering column 710, a deck assembly 720 having a stand-up plate 721 and a rear wheel assembly 770, a steering mechanism 730, and an optional removable bag 799, wherein the steering column 710 is in a straight, upright position. The stand-up plate 721 is configured to tilt to one side toward the inner periphery of a turning curve and is configured to support the rider who typically stands on it.

[0469] It is important to note that the difference between scooter 700 and scooter 701 is that scooter 700 includes an electrically operated folding mechanism, while scooter 701 includes a manually operated folding mechanism. Otherwise, scooter 700 and scooter 701 are identical. Therefore, when referring to mechanisms that do not involve a folding mechanism, the descriptions relating to scooter 700 also apply to scooter 701.

[0470] Scooter 700 (and scooter 701) are similar to scooter 500, but specifically (without limitation) scooter 700 differs from scooter 500 in the implementation of the following mechanisms: steering mechanism 730 relative to steering mechanism 530; tilt synchronization unit 740 relative to tilt synchronization unit 540; tilt synchronization assembly 755 relative to tilt synchronization component 555; pivot interface unit 760 relative to pivot interface unit 560; and tilt conveying unit 790 relative to tilt conveying unit 590.

[0471] Scooter 700 Figure 42a - As shown in Figure 54d. Figure 42a - Figure 54d is compared with the scooter 500. Figures 22-41d Similar (without limitation). Variations of the scooter 700 embodiment compared to the scooter 500 embodiment are described below.

[0472] Referencing the steering mechanism 730 Figure 42a - Figure 52d. The steering mechanism 730 enables the rider to turn the steering column 710 to turn the scooter 700 to the left or right as desired. Figure 42b The schematic diagram shows a scooter 700 according to the present disclosure, in which the steering column 710 is pivoted to the left along direction 717 and thus also tilts to the left. Figure 43 This is a rear-view perspective view of a scooter 701 according to the present disclosure, wherein the steering column 710 pivots to the left and thus also tilts to the left. Tilt measurement is indicated at a constant pre-configured rate. In one embodiment, the steering column 710 is subdivided into an upper column 712 and a lower column 714, wherein the upper column 712 can slide retractably on the lower column 714.

[0473] The steering mechanism 730 also includes a pair of front wheels 732, which are connected to the steering column 710 via the steering mechanism. When the steering column 710 pivots, the front wheels (732) L 732 R Each of them also pivots in the same direction via wheel pivoting mechanism 750, such as Figure 44 As shown. Figure 44This is a top perspective view of the front portion of a scooter 701 according to the present disclosure, wherein a non-limiting example of the wheel pivoting mechanism 750 shown is based on the Ackermann Steering Principle (ASP). In such an ASP steering mechanism, the inner front wheel needs to rotate at a different angle than the outer wheel because they rotate at different radii. The ASP steering mechanism is the geometric arrangement of the link components (e.g., 767, 752, 754, 756) in the wheel pivoting mechanism 750, which is designed to rotate the inner and outer wheels at appropriate angles. Any other mechanism known in the art for coordinating the pivoting of two front wheels, such as in a car (but not, for example, in a "carriage" mechanism), can be used. The exemplary wheel pivoting mechanism 750 includes a pivot receiving link component 756 that receives pivoting motion from the steering column 710, which is transmitted to the front wheel 732 via a pair of axially moving links 752 and 754. L and 732 R This is transmitted to the corresponding linkage component 756, and the corresponding front wheel 732 is rotatably attached to the corresponding linkage component 756. It should be understood that when the scooter 700 is in a turning position, the pivoting front wheel (732)... L 732 R Maintaining an upright orientation, where both wheels remain firmly on the road surface when traveling at a reasonable speed. Individual linkage components 756 (756) L 756 R It also includes the corresponding independent shaft 758 (758) L 758 R When turning, the corresponding front wheel (732) L 732 R It pivots around axis 758.

[0474] Figure 45a This is a front partial view of scooter 700 / 701, schematically illustrating a non-limiting example of the steering mechanism 730, where some parts (related to the steering column 710) have been removed for illustrative purposes only, and where scooter 700 is shown in the unfolded position (state). Similarly, Figure 46a This is a front view of the scooter 700, schematically showing the steering mechanism 730, where some obscured parts have been removed for illustrative purposes only, and where the scooter 700 is shown in a position at the moment of a left turn.

[0475] Figure 45b This is a front view schematic diagram of the steering mechanism 730 of the scooter 700 / 701, shown in the unfolded position. Figure 45b The diagram illustrates the components involved in facilitating left or right turns for the scooter 700 / 701. Similarly, Figure 46b This is a front view schematic diagram of the steering mechanism 730 of the scooter 700 / 701, shown in a position at the moment of a left turn. Figure 46b The diagram illustrates activities that promote scooter 700 / 701 turns (in...) Figure 46b The non-restrictive example shown is a component for turning left.

[0476] The steering mechanism 730 is a component that utilizes the automatic tilting of the steering column 710 to assist in facilitating the steering of the scooter 700 / 701. It includes the steering column 710, a pair of front wheels 732, a tilt synchronization unit 740, and a pair of balance actuators 792. UP 792 LW (This is shown as a pair of springs only, for example.) The balance actuator 792 can also be implemented as, for example, a pair of pneumatic or hydraulic mechanisms. The steering mechanism 730 also includes the following interface components: a pivot interface unit 760, a tilt conveyor unit 790, and a non-pivot frame element 780.

[0477] It should be understood that while the rider pivots the steering column 710, the pivot interface unit 760, which is firmly attached to the steering column 710, pivots together with the steering column 710, while the tilting delivery unit 790, which is pivotally connected to the non-pivoting frame element 780 at the bearing 785, tilts to one side in sync with the pivoting movement of the steering column 710.

[0478] This pair of similar balance actuators 792 (792 UP 792 LW ) Installed on a common vertical support rod 795 (see example) Figure 45a ), including a pair of end stops (upper end stop 791) UP and lower end stop 791 LW Limiting the balance actuator (792) UP 792 LW The movement of the balance actuator (792) UP 792 LW An end stop (791) is arranged on the vertical bearing rod 795. UP 791 LW Between them, there is an upper open end and a lower open end (see example). Figure 46a and Figure 46b Balance actuator 792 UP and 792 LW Separated by a force-transmitting ring 794 arranged therebetween, wherein the force-transmitting ring 794 receives from the inclined conveying unit 790 along the vertical bearing rod 595 and toward the balancing actuator 792.
