The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1, 2 and 3, a vehicle 10 according to an embodiment includes a first frame 100, a first wheel 200, a second frame 300, a second wheel 400 and a steering shaft 500.
The first frame 100 is used for steering. In the present embodiment, the first frame 100 has a steering portion 110, a wheel mounting portion 120, and a guide portion 130.
The steering portion 110 is provided at one end of the guide portion 130. The steering control portion 110 is provided with a handle 140. The handle 140 is fixedly connected to the steering control 110 for controlling steering. It will be appreciated that in other embodiments, the steering control 110 may be manipulated by other automatically controlled steering mechanisms.
The wheel mounting portion 120 is located below the steering portion 110. The wheel mounting portion 120 is a bifurcated structure for mounting the first wheel 200.
The other end of the guide 130 is limitedly connected to the steering shaft 500. The limiting connection means that the connection part of the steering part 130 and the steering shaft 500 is fixed in position relative to the steering shaft 500. It will be appreciated that when the steering shaft 500 has a plurality of adjustable connection points for the guide 130, the above-described limit connection is also provided that the connection point of the guide 130 to the steering shaft 500 is fixed in position relative to the steering shaft 500 at each connection point. The limited connection of the guide 130 to the steering shaft 500 serves to limit the rotation of the guide 130 relative to the steering shaft 500 in the horizontal direction.
When the vehicle 10 travels (in the folded configuration, travel in the unfolded state), the positions of the steering portion 110, the wheel mounting portion 120, and the guide portion 130 are fixed. The steering control portion 110, the wheel mounting portion 120 and the guiding portion 130 may be integrally formed, or may be formed by fixedly connecting or limiting a plurality of connecting rods. It is to be appreciated that in other embodiments, the specific structure of the first frame 100 is not limited to that described above, as long as the first frame 100 can be used to mount the first wheel 200 and make a limited connection with the steering shaft 500.
The first wheel 200 is provided on the first frame 100 and is rotatable with respect to the first frame 100. In the present embodiment, the rotation plane of the first wheel 200 is fixed relative to the steering control portion 110, the wheel mounting portion 120 and the guiding portion 130, so that the first wheel 200 is not steerable relative to the first frame 100, that is, the vehicle 10 of the present embodiment is not steerable by the conventional horizontal rotation of the first wheel 200, unlike the conventional steering by the horizontal rotation of the first wheel 200.
The first wheel 200 of the present embodiment has one. The first wheel 200 is rotatably mounted to the wheel mounting portion 120 of the first frame 100. It is understood that in other embodiments, the mounting of the first wheel 200 to the first frame 100 is not limited to the above, nor is the wheel mounting 120 limited to a diverging configuration. The number of the first wheels 200 is not limited to one, and for example, two or more first wheels 200 may be connected by a deformable link structure, and the connection structure may be deformed during the tilting steering, for example, may be deformed from a rectangular shape to a non-rectangular parallelogram shape.
The second frame 300 is used for an operator to stand or sit on. For a vehicle that can be ridden, a hip support assembly may be provided on the second frame 300. The hip support assembly may be fixedly coupled to the second frame 300 or may be foldably coupled to the second frame 300.
In the present embodiment, the second frame 300 includes a main body portion 310 and a connecting portion 320. The connecting portion 320 is disposed at an acute angle or perpendicular to the main portion 310. Preferably, the connection portion 320 is disposed at an acute angle, such as an acute angle of 5 ° to 85 °, with the main body portion 310. More preferably, the angle between the connecting portion 320 and the main body portion 310 is 10 ° to 40 °. The steering shaft 500 is conveniently installed by providing the connection part 320 disposed at a certain angle with the main body part 310. It is to be understood that, in other embodiments, the second frame 300 is not limited to the structure of the main body 310 and the connecting portion 320, but may be only the main body 310, and the main body 310 and the connecting portion 320 may be considered to be disposed at an angle of 0 °.
The second wheel 400 is rotatably provided on the body portion 310 of the second frame 300. In this embodiment, there are two second wheels 400, and two second wheels 400 and one first wheel 200 form a tricycle-type structure. It is appreciated that in other embodiments, the number of second wheels 400 is not limited to two, as may be only one, or three or more, etc.
The total number of the first wheels 200 and the second wheels 400 is preferably at least three, but may be two, and for the total number of two, at least one of the first wheels 200 and the second wheels 400 has a larger wheel width so as to form a stable support when steering.
The steering shaft 500 is rotatably provided to the second frame 300. Specifically, in the present embodiment, the steering shaft 500 is rotatably connected to the connection portion 320 of the second frame 300 through a bearing. The rotation plane of the bearing is parallel to the connection portion 320, and the axial direction of the steering shaft 500 is perpendicular to the rotation planes of the connection portion 320 and the bearing.
It will be appreciated that in other embodiments, the steering shaft 500 is not limited to being rotatably coupled to the second frame 300 via bearings.
In the present embodiment, the steering shaft 500 is deviated toward the rear of the second frame 300 from its bottom to its top in a direction opposite to the vertical direction. Preferably, the steering shaft 500 has an acute angle, such as between 5 ° and 85 °, with the vertical direction. Still more preferably, the steering shaft 500 has an angle of 10 ° to 40 ° with respect to the vertical direction. The included angle is set so that after the first frame 100 and the second frame 300 are connected through the steering shaft 500, the first frame 100 can tilt relative to the second frame 300 through the steering shaft 500, and when an operator needs to turn, the first frame 100 can tilt relative to the second frame 300, so that the first wheel 200 can be synchronously driven to tilt and turn, and the second frame 300 and the second wheel 400 can be synchronously driven to deflect in a direction opposite to the travelling direction of the first wheel 200 through the steering shaft 500, so that the travelling direction of the second wheel 400 deviates from the original direction and is matched with the first wheel 200 to turn. Since the second wheel 400 also cooperates to steer when steering, is no longer limited to steering by the first wheel 200, the required turning radius is small.
Further, as shown in fig. 1 and 2, it has been found through the study of the present embodiment that, when the second frame 300 and the second wheel 400 are caused to deflect in the direction opposite to the traveling direction of the first wheel 200 by the above-mentioned arrangement of the steering shaft 500 and the corresponding angle, the first frame 100 and the first wheel 200 are also subsequently driven to deflect in the required steering direction due to the rotation of the steering shaft 500 relative to the second frame 300 as the steering proceeds, i.e. the first frame 100 and the first wheel 200 are gradually changed from tilting relative to the second frame 300 to steering rotation relative to the second frame 300 in the horizontal direction until the first frame 100 is reset to be vertical.
Further, as shown in fig. 4 and 5, in other embodiments, when the steering shaft 500 is directed from the bottom portion thereof to the top portion thereof toward the first frame 100 with respect to the vertical direction, steering can also be achieved in a similar manner by arranging the steering shaft 500 at an angle to the vertical direction similar to that described above, except that, at the time of steering operation, it is necessary to tilt the first frame 100 in a direction different from the steering direction. The steering mode can be applied to some interesting vehicles, so that operators experience different steering feelings.
In this embodiment, the steering shaft 500 is located between the first wheel 200 and the second wheel 400 of the vehicle 10 to facilitate the operator tilting the first frame 100.
In addition, in the present embodiment, the vehicle 10 further includes a control device (not shown), a warning device (not shown), a lighting device (not shown), a wireless communication device (not shown), a rechargeable power supply assembly (not shown), and a driving device (not shown). The control device, the rechargeable power supply assembly and the driving device are provided on the first frame 100 and/or the second frame 300. The control device and the chargeable power supply assembly are electrically connected with the driving device. The lighting device, the warning device and the wireless communication device are respectively and electrically connected with the control device and the chargeable power supply assembly. The warning device can be an LED tail lamp, a steering lamp and the like. The rechargeable power supply assembly may be, but is not limited to, a lithium ion battery, a metal air battery, a fuel cell, a solar cell, a lead acid battery, a nickel hydrogen battery, or the like. The drive device is coupled to the first wheel 200 and/or the second wheel 400 to drive rotation of the respective wheels. It is understood that in other embodiments, the vehicle 10 may be a foot-operated drive or the like.
The rotation plane of the first wheel 200 of the vehicle 10 is fixed relative to the position of the first frame 100, so that the first wheel 200 is not steerable relative to the first frame 100, that is, steering cannot be achieved by horizontally rotating the first wheel 200. The first frame 100 and the second frame 300 are rotatably connected, when an operator needs to turn, the operator can tilt the first frame 100 to enable the traveling direction of the first wheel 200 to be inconsistent with the traveling direction of the second wheel 400, and the deviation direction of the second wheel 400 is just matched with the traveling direction of the first wheel 200 in a turning way, so that the turning radius is small, and the operator can easily and conveniently realize turning. The vehicle 10 has the advantages of safety, easy operation, simple structure, low cost, small turning radius, etc.
Further, by arranging the steering shaft 500 to be deviated from the bottom to the top thereof toward the tail of the second frame 300 with respect to the vertical direction, and the angle formed by the axial direction of the steering shaft 500 and the vertical direction is preferably an acute angle, the direction in which the operator tilts the first frame 100 is consistent with the direction in which the vehicle 10 rotates, so that the balance between the gravity of the body and the centrifugal force generated during steering is ensured, thereby ensuring the safety of the operator; in addition, the steering mode is more in line with human engineering mechanics and physical intuition, can bring more experience and riding fun to operators, and has higher practical value.
It will be appreciated that in other embodiments, the entire first frame 100 is not limited to being tiltable or rotatable relative to the second frame, as long as the end of the first frame 100 near the steering shaft 500 and the end of the second frame 300 near the steering shaft 600 are capable of rotating relative to each other, and the traveling directions of the first wheel 200 and the second wheel 400 are different, so long as synchronous cooperative steering is achieved, and accordingly, the vehicle 10 travels straight when the end of the first frame 100 near the steering shaft 500 and the end of the second frame 300 near the steering shaft 500 are in the same direction; when the end of the first frame 100 near the steering shaft 500 and the end of the second frame 300 near the steering shaft 500 rotate around the steering shaft 500 but are not in the same direction, the first frame 100 drives the first wheel 200 to deflect, and can synchronously drive the second frame 300 and the second wheel 400 to deflect in a direction opposite to the steering direction of the first wheel 200 through the steering shaft 500, so that the travelling direction of the second wheel 400 deviates from the original direction to be matched with the first wheel 200 for steering.
In addition, it will be appreciated that in other embodiments, the steering mode of the present embodiment may be combined with the conventional steering mode in which the handle is turned horizontally to steer the first wheel.
The term "fixed" as used herein refers to the relative fixing of the positions of the components, including fixing by welding, screwing, etc., and also includes the relative fixing of the positions of the components in a certain stage of the multistage adjustable state.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
