detailed description

Preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the figure shows The preferred embodiments of the present disclosure are shown, but it should be understood that the present disclosure may be embodied in various forms and not limited by the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

The present disclosure introduces a scooter including a novel steering structure, so that the wheel of the scooter can be controlled by swinging the swing lever, in view of the problem that the steering mode of the existing scooter described in the background is unstable and unfavorable for control. Steering simplifies steering operations. Further, since the human body naturally tilts in order to resist the centrifugal force when the vehicle is turning, the scooter based on the present disclosure only needs the user to tilt the swing lever together when the body is tilted, and the steering action can be completed. Thereby, the steering operation can be further simplified.

1 to 3 are schematic views showing the structure of a scooter at different viewing angles based on an embodiment of the present disclosure. The scooter of the embodiment of the present disclosure may be an electric scooter, a scooter of other power, or an unpowered scooter. Further, the scooter of the embodiment of the present disclosure may be a reverse three-wheel or four-wheeled pulley.

Referring to FIGS. 1-3, the scooter of the embodiment of the present disclosure includes a fixed bracket 1, two steering wheels, two steering wheel mounting plates, two connecting rods, a swinging bar 5, and a swinging disk 6. Wherein, the two steering wheels respectively correspond to the two steering wheel mounting plates, only the left steering wheel 2, the steering wheel mounting plate 3 and the connecting rod 4 are marked in the figure, it should be known that the following is for the left steering wheel 2, steering The description of the wheel mounting plate 3 and the connecting rod 4 also applies to the right steering wheel, the steering wheel mounting plate and the connecting rod.

The steering wheel 2 is preferably the front wheel of the scooter, and the inside of the steering wheel 2 is mounted on the corresponding steering wheel mounting plate 3. The structure of the steering wheel 2 here is the same as that of the existing wheel, and its size can be selected according to actual conditions.

The steering wheel mounting plate 3 is arranged to be rotatable about a plate axis perpendicular to the axis of the shaft of the steering wheel 2 and intersecting the centerline of the shaft of the steering wheel 2, the plate axis being substantially perpendicular to the horizontal plane. Thus, when the steering wheel mounting plate 3 is subjected to a force inclined with respect to the axis of the plate, the steering wheel 2 connected thereto can be rotated to provide a steering foundation for the steering wheel 2.

The steering wheel mounting plate 3 is disposed on the fixed bracket 1. The lower end of the swing link 5 is pivotally connected to the fixed bracket 1 so that the swing lever 5 can swing left and right. The swash plate 6 is fixed to the swinging rod 5, and one end of the connecting rod 4 is connected to the swash plate 6, and the other end is connected to the steered wheel mounting plate 3.

Wherein, in order to apply force to the steering wheel mounting plate 3 when the connecting rod 4 is applied, the steering wheel is mounted The plate 3 can drive the steering wheel 2 to rotate about the axis of the plate, and the position of the connecting rod 4 connected to the corresponding steering wheel mounting plate 3 should be a position of the force biased away from the axis of the plate.

In this way, by swinging the swing lever 5 to the left or to the right, the swinging disc 6 can be swung in a corresponding direction, so that the two connecting rods respectively apply the thrust and the pulling force to the corresponding force receiving positions on the corresponding steering wheel mounting plate. In turn, the two steering wheel mounting plates drive the two steering wheels to deflect in the same direction.

For example, when swinging the swing lever to the left, the left connecting lever applies a leftward thrust to the left steering wheel mounting plate, and the biasing portion deviates from the plate axis of the left steering wheel mounting plate under the thrust. The steering wheel mounting plate on the left will drive the left steering wheel to the left. Correspondingly, when swinging the swing lever to the left, the right connecting tie rod applies a pulling force to the left of the right steering wheel mounting plate. Since the biasing portion deviates from the plate axis of the right steering wheel mounting plate, under the pulling force, the right side The steering wheel mounting plate will drive the right steering wheel to the left. Thus, under the action of the two rotating wheels, the scooter will slide to the left. Thus, by swinging the swing lever to the left or to the right, it is possible to control the two steering wheels (preferably the front wheels) of the scooter to turn in the corresponding directions, and the steering operation is simple and convenient.

As described above, the swash plate 6 is fixedly coupled to the swing link 5. As shown in FIG. 2 and FIG. 3, the swinging rod 5 may be provided with a first longitudinal rod 51 extending rearward. The first end of the first longitudinal rod 51 is connected to the swinging rod 5, and the swinging disc 6 can pass through the pivot shaft. The connection to the pendulum rod 5 is achieved by connecting to the first longitudinal rod 51. In addition, FIG. 2 and FIG. 3 are only a specific connection manner of the oscillating disc 6 and the swinging rod 5. The specific fixed position of the swash plate 6 fixed on the swinging rod 5 can be determined according to the spatial structure required for the steering. It may be fixed to the rear of the swing link 5, or may be fixed to both sides of the swing link 5, but is preferably fixed to the rear of the plane formed by the left and right mounting plates (here, the rear is the rear with respect to the traveling direction).

As an extension, as shown in FIGS. 1-3, the fixing bracket 1 may include a horizontally disposed lower crossbar 11, which may further include a horizontally disposed upper crossbar 7, an upper crossbar 7 and a lower crossbar The left and right ends of the 11 are respectively pivotally connected to the upper and lower ends of the two steering wheel mounting plates, thereby forming a parallelogram structure, the lower end of the swinging bar 5 is pivotally connected to the middle position of the lower crossbar 11, and the swinging bar 5 is also pivoted. Connected to the middle position of the upper crossbar 7. Here, the upper crossbar 7 can be pivotally connected to the first longitudinal rod 51.

The shape of the quadrangular structure formed based on the upper crossbar 7, the lower crossbar 11, and the two steering wheel mounting plates is not fixed. Specifically, the swing link 5 is connected to the movable parallelogram structure so that When the swing lever 5 is swung left or right, the parallelogram structure is deformed, so that the left steering wheel mounting plate and the right steering wheel mounting plate are inclined in one direction, thereby causing the two steering wheels to tilt in the same direction.

That is to say, by swinging the swing lever to the left or right, the parallelogram structure can be deformed, so that the left steering wheel mounting plate and the right steering wheel mounting plate are inclined in the same direction, thereby driving the two steering wheels to tilt.

4 and 5 show schematic views of the scooter when tilted in different directions. Referring to FIGS. 4 and 5, when the steering wheel is tilted, the gravity G of the scooter can be decomposed into a horizontal component F1 and a downwardly directed component F2. Wherein, the magnitude of the component force F2 of the gravity G tilting downward is equal to the support force of the ground, and the component force F1 of the gravity G horizontal direction can be used as the centripetal force to cancel the centrifugal force at the time of steering.

Therefore, the swing lever, the connecting rod, the swash plate, and the parallelogram structure may preferably be disposed such that the gravity horizontal direction component corresponding to the tilt angle of the steering wheel is substantially the same as the centrifugal force corresponding to the deflection angle of the steering wheel at the predetermined traveling speed. And in the opposite direction. In this way, when steering, there is no need to apply additional force to offset the centrifugal force caused by the steering.

So far, the easy-to-operate steering mechanism of the steering wheel in the scooter of the present disclosure and the tilting mechanism that can be used to counteract the centrifugal force are highlighted in conjunction with FIGS. The specific implementation structure of the steering mechanism and the tilting mechanism of the steering wheel in the scooter of the present disclosure will be further described in detail below in conjunction with the preferred embodiment.

As shown in FIG. 1 to FIG. 5, four connecting members may be respectively pivotally connected between the left and right ends of the upper crossbar 7 and the lower crossbar 11 and the upper and lower sides of the two steering wheel mounting plates to form a movable body. Quadrilateral structure. Wherein the first ends of the four connecting members are respectively pivotally connected to the ends of the upper cross bar 7 or the lower cross bar 11, and the second ends of the four connecting members are pivotally connected to the corresponding steering wheel mounting plates.

In order to allow the formed parallelogram structure to be deformed under the swing of the swing link 5, the ends of the four connecting members connected to the upper cross bar 7 or the lower cross bar 11 should be movably connected. Thus, when the swing lever 5 swings to the left or to the right, the angle between the upper crossbar 7 and the lower crossbar 11 and the corresponding steering wheel mounting plate is changed, thereby making the left steering wheel mounting plate and the right steering wheel The mounting plate is tilted to drive the steering wheel to tilt.

In addition, the connection of the four connectors to the respective steering wheel mounting plates is such that the respective steering wheel mounting plates are rotatable about the corresponding plate axis to provide a basis for steering of the steering wheel.

Thus, when the swing lever 5 is swung, both the steering wheel steering and the steering wheel tilting effects can be achieved at the same time.

The connecting members 8 of the four connecting members for connecting the lower crossbar 11 and the left steering wheel mounting plate 3 are indicated in Figs. The connection between the steering wheel mounting plate 3 and the lower crossbar 11 will be described below by taking the connecting member 8 as an example. The connection manner of the other three connecting members can be referred to the relevant description of the connecting member 8.

One end of the connecting member 8 is connected to the lower cross bar 11, here a movable connection, so that the angle between the lower cross bar 11 and the steering wheel mounting plate 3 can be changed, and the quadrangular structure can be operated by the four connecting members. Deformation. The other end of the connecting member 8 is connected to the steering wheel mounting plate 3, which is also an active connection. The bottom of the connecting member of the upper portion of the steering wheel mounting plate 3 is also movably connected to the steering wheel mounting plate 3, and the steering wheel mounting plate 3 is rotatable about its plate axis by the two connecting members.

FIG. 6 shows a detailed structural diagram of the steering wheel mounting plate 3 connected to the steering wheel 2.

As shown in Fig. 6, the steering wheel mounting plate 3 may include a base portion 31 that is parallel to the radial direction of the steering wheel 2 and two extensions that extend away from the steering wheel 2 at both ends of the base portion 31, as shown in the figure at the lower end of the base portion 31. The extension 32, the base 31 and the two extensions may be arranged in a "U" shape. The steering wheel 2 is pivotally coupled to the base 31, and the upper end of the connector 8 is pivotally coupled to the extension 32 at the lower end of the base 31. Here, the extending portion 32 may be provided with a through hole, and the upper end of the connecting member 8 may be inserted into the through hole to realize the pivotal connection of the connecting member 8 and the extending portion 32.

Further, referring to FIG. 6, the steering wheel mounting plate 3 may further include a socket connecting portion 33 extending substantially perpendicular to the axis of the plate, and a first through hole 34 is provided at a position on the socket connecting portion 33 that is offset from the axis of the plate. The connecting rod 4 corresponding to the steering wheel mounting plate 3 can be connected to the first plunger 41 through a universal joint, and the other end of the first plunger 41 can be inserted into the first through hole 34.

As described above, the other end of the connecting rod 4 can be connected to the swash plate 6. Fig. 7 shows the specific structure of the swash plate 6 and the specific connection of the other end of the connecting rod 4 to the swash plate 6.

Referring to Fig. 7, the swash plate 6 includes a vertical portion 61 parallel to the swing link 5 and a horizontal portion 62 extending from the lower end of the vertical portion. The horizontal portion 62 is symmetrically disposed with two second through holes through which the second end of the connecting rod 4 passes. The universal joint is connected to the first end of the second plunger 12, and the second end of the second plunger 12 is inserted into the second through hole on the left side.

Up to this point, the specific structure of connecting the swing link 5 to the left steering wheel mounting plate 3 by connecting the tie rod 4 will be described in detail with reference to FIGS. 6 and 7. The connection manner of the swing lever 5 and the right steering wheel mounting plate and the connection manner of the swing lever 5 and the left steering wheel mounting plate 3 are the same, and details are not described herein. Thus, when the swing lever 5 is swung left and right, the swinging disc 6 can be driven in the corresponding direction. The swinging causes the two connecting rods to respectively apply thrust and pulling force to the corresponding force receiving positions on the corresponding steering wheel mounting plate, so that the two steering wheel mounting plates drive the two steering wheels to deflect in the same direction.

As shown in FIG. 8, as an extension, the scooter of the present disclosure may further include two left and right pedal assemblies. Only the left pedal assembly is shown in the figure, wherein the structure of the right pedal assembly is the same as that of the left pedal assembly, so the description of the left pedal assembly below applies equally to the right pedal assembly.

The two connecting portions and the two connecting rods of the two pedal assemblies may be arranged in an "M" shape, wherein the swinging rod 5 is swung left or right to sandwich the connecting rods between the left and right sides and the connecting portion The angles are changed so that the pedal portions are tilted in the same direction.

In this way, when the user is in use, the two feet can stand apart from each other and can hold the swing bar. In this way, the support points of the two foot stations below, together with the support points above, form a triangle, and the person can stand stably in the car, even if the car is stationary, it will not fall off the car.

Preferably, the inclination angle of the pedal portion is substantially the same as the inclination angle of the steering wheel. Thus, when turning, the user's gravity can also be decomposed into a downwardly directed component and a horizontal component, wherein the horizontal component can be used to offset the centrifugal force caused by the steering.

In addition, as shown in FIG. 8, the swinging rod 5 may further be provided with a second longitudinal rod 52 extending rearward. The first end of the second longitudinal rod 52 is connected to the swinging rod 5, and the second end of the connecting rod 22 is pivotable. The shaft is coupled adjacent the second end of the second longitudinal rod 52.

Further, the fixing bracket 1 may further include three third longitudinal rods and a rear horizontal rod 13 , wherein the three third longitudinal rods extend from the front to the rear, and the first ends thereof are fixedly connected to the lower cross rails 11 respectively. The two ends are connected to the rear crossbar 13, respectively. The third longitudinal rod 12 on the left is indicated in the drawing. Referring to Figure 8, the lower end of the connecting portion 212 in the left pedal assembly can be pivotally coupled adjacent the second end of the third longitudinal rod 12.
