The present application is a National Stage of International Application No. PCT/CN2021/087428, filed on Apr. 15, 2021, which claims the benefit of priority to Chinese Application No. 202021243529.3, filed on Jun. 29, 2020, both of which are incorporated by reference herein in their entireties for all purposes.
The present disclosure relates to the field of toy vehicle technologies, and more particularly, to a drift motorcycle.
Toy motorcycles having a drifting function are more cool and fun than ordinary toy motorcycles in terms of driving skills and traveling smoothness. At present, the drifting function of toy motorcycles on the market achieves the drifting effect of lateral translation of the body by adding transverse wheels and controlling the steering of the transverse wheels. In the drifting process, a body of the motorcycle does not tilt, so that the drifting effect is not realistic enough, and the motorcycle is easy to roll over.
The technical solution of the present disclosure provides a drift motorcycle. The drift motorcycle includes a body and an advancing unit arranged on the body and configured to provide advancing power for the body, and the body is further provided with a tilting unit and a transverse moving unit; the tilting unit is movably mounted on the body, and two ends of the tilting unit extend from two sides of the body to control the body to switch between an upright state and a tilting state; and the transverse moving unit is arranged at two sides of the body, and the transverse moving unit is in contact with a traveling surface when the tilting unit controls the body to switch to the tilting state, to generate transverse power along a width direction of the body.
With reference to accompanying drawings, the disclosed content of the present disclosure will become easier to understand. It should be understood that these accompanying drawings are only for the purpose of illustration and are not intended to limit the scope of protection of the present disclosure. In the figures:
Specific implementations of the present disclosure will be further described below with reference to accompanying drawings.
It is easy to understand that according to the technical solution of the present disclosure, a variety of structural modes and implementation modes can be mutually replaced by those skilled in the art without changing the substantive spirit of the present disclosure. Therefore, the following specific implementations and accompanying drawings are only exemplary descriptions of the technical solution of the present disclosure, and should not be regarded as the whole of the present disclosure or as the limitation or restriction of the technical solution of the present disclosure.
The directional terms of up, down, left, right, front, rear, front side, rear side, top, bottom and other orientations mentioned or possibly mentioned in this description are defined relative to the structures shown in the accompanying drawings. They are relative concepts, so they may change accordingly according to their different positions and use states.

A drift motorcycle according to embodiments of the present disclosure, as shown in
It should be noted that, as shown in
Specifically, the tilting unit 003 is configured to provide a tilting force for the body 001, and the transverse moving unit 004 is configured to provide transverse power for the body 001. The advancing power, the tilting force and the transverse power function jointly act on the body 001 to realize the tilt drifting.
Both the advancing unit 002 and the transverse moving unit 004 may be designed as wheels to drive the body 001 to move in the length direction Y and the width direction X through rolling of the wheels.
When the motorcycle moves forward, the tilting unit 003 does not provide the tilting force, the transverse moving unit 004 does not drive or is not in contact with the traveling surface, and the body 001 only moves forward under the advancing power provided by the advancing unit 002.
When the motorcycle drifts, the tilting unit 003 provides the tilting force by moving in the width direction X of the body 001 to tilt the body 001 to the left side or to the right side. The advancing unit 002 and the transverse moving unit 004 drive simultaneously to provide the advancing power and the transverse power for the body 001 respectively. The advancing power is along the length direction Y of the body 001, and the transverse power is along the width direction X of the body 001, the advancing power and the transverse power are perpendicular to each other, and combined action of the two types of power provides oblique power for the body 001. At this time, the body 001 tilts to the left side or to the right side and moves obliquely simultaneously, thus showing an effect of tilt drifting.
As shown in
According to embodiments of the present disclosure, the advancing unit 002 and the transverse moving unit 004 drive the body 001 to move obliquely, and the body 001 is tilted through the cooperation of the tilting unit 003, thus realizing the effect of tilt drifting of the motorcycle, simulating the drifting process of the real motorcycle, and improving the driving skills and traveling smoothness of the motorcycle.
In one embodiment, as shown in
Specifically, the balancing assembly 01 is arranged along the width direction X of the body 001. The two ends of the balancing assembly 01 are located at the left side and the right side of the body 001 respectively. The driving assembly 02 causes the left side and the right side of the body 001 to be unbalanced by driving the balancing assembly 01 to move, thus changing a center of gravity of the body 001 and tilting the body 001.
The driving assembly 02 may control the balancing assembly 01 to move in the width direction X of the body 001, and may further control the balancing assembly 01 to rotate relative to the body 001.
In the tilting unit 003 according to the embodiments of the present disclosure, the movable balancing assembly 01 is mounted on the body 001, so that the weight and structure of the left side and the right side of the body 001 may become asymmetric, to tilt the body 001.
In one embodiment, as shown in
The balance detecting assembly 08 may be designed as a contact switch. The balancing assembly 01 is not in contact with the contact switch when it is in the unbalanced state. Only when the balancing assembly 01 is in the balanced state, it may be in contact with the contact switch. Therefore, the contact switch may detect whether the balancing assembly 01 is restored to the balanced state, so as to control the driving mechanism to stop driving.
Specifically, the balance detecting assembly 08 and the driving assembly 02 may communicate with each other through a controller, such as a one-chip computer. When the balance detecting assembly 08 detects the balancing assembly 01, the balance detecting assembly sends a signal to the controller, and the controller disconnects the power supply of the driving assembly 02, thus controlling the driving assembly 02 to stop driving, so that the balancing assembly 01 remains in the balanced state.
In one embodiment, as shown in
The swing bar is arranged symmetrically in the left-right direction; when the body 001 is in the upright state, a length of the swing bar extending from the left side and a length of the swing bar extending from the right side of the body 001 are identical, and the swing bar is in the balanced state; and at this time, the body 001 is symmetrical in the left-right direction;
Specifically, as shown in
An upper end of the swing arm 12 is the coupling end coupled to the central swing member 11, and a lower end is the free end. The central swing member 11 is configured to couple to the driving assembly 02. When the driving assembly 02 drives the central swing member 11 to swing to the left, the swing bar moves to the left side as a whole, and at this time, the lower end of the swing arm 12 on the left side abuts against the traveling surface, to push the body 001 to tilt to the right side. When the driving assembly 02 drives the central swing member 11 to swing to the right, the swing bar moves towards the right side as a whole, and at this time, the lower end of the swing arm 12 on the right side abuts against the traveling surface, to push the body 001 to tilt to the left side.
The swing arm 12 is resiliently and rotatably coupled to the central swing member 11. The swing arm 12 is squeezed by the traveling surface and rotates slightly relative to the central swing member 11 when the lower end of the swing arm 12 abuts against the traveling surface. If the body 001 returns to the upright state, the swing arm 12 is resiliently restored. This arrangement reduces the impact on the swing arm 12 when the body 001 tilts, and prevents the swing arm 12 from being damaged.
The driving assembly 02 includes a swing bar power device 21 and a swing bar transmission assembly 22. The swing bar transmission assembly 22 couples the swing bar power device 21 and the central swing member 11. The swing bar power device 21 drives the central swing member 11 to swing through the transmission of the swing bar transmission assembly 22.
The swing bar power device 21 may adopt a rotary motor or an extension-retraction motor. The swing bar transmission assembly 22 is configured to match the output power of the swing bar power device 21 with the central swing member 11. For example, a rotating force of the rotary motor is converted into a pushing force in the left-right direction of the central swing member 11. Or, when an extension-retraction direction of an extension-retraction shaft of the extension-retraction motor is not in a same direction as a swinging direction of the central swing member 11, the swing bar transmission assembly 22 may drive the central swing member 11 to swing when the extension-retraction shaft extends or retracts.
As shown in
In this embodiment, the swing bar power device 21 adopts a rotary motor, the swing bar input gear 221 is fitted over a rotating shaft of the rotary motor, and the rotating shaft drives the swing bar input gear 221 to rotate synchronously when rotating.
The swing bar input gear 221 may be meshed with the swing bar output gear 222 to directly drive the swing bar output gear 222 to rotate. The swing bar output gear 222 may also be indirectly driven through at least one swing bar transmission gear 223. As shown in
The swing gear 111 on the central swing member 11 is meshed with the swing bar output gear 222. An arc where the swing gear 111 is located is arranged along the width direction X of the body 001. The swing bar output gear 222 drives the swing gear 111 to rotate. The central swing member 11 is controlled to swing in the width direction X of the body 001 by controlling a rotating direction of the swing bar power device 21.
Alternatively or additionally, as shown in
In one embodiment, as shown in
The swing arm 12 is designed to two sections, namely the first arm body 121 and the second arm body 122. A rotation axis L1 of the first arm body 121 and the central swing member 11 is arranged along the length direction Y of the body 001. A rotation axis L2 of the second arm body 122 and the first arm body 121 is arranged along the height direction Z of the body 001 when the first arm body 121 rotates into a condition in which the first arm body 121 is arranged along the width direction of the body 001. In addition, the rotation axis L2 is always perpendicular to the rotation axis L1 during the rotation of the first arm body 121. Restoring torsion springs are coupled between the first arm body 121 and the central swing member 11 and between the first arm body 121 and the second arm body 122 to realize resilient restore of the swing arm 12.
The roller 123 is configured to reduce friction between the swing arm 12 and the traveling surface, so that the body 001 moves forward and drifts more smoothly.
In one embodiment, as shown in
The side wheel assembly 07 drives the body 001 to move along the width direction X when rotating, and the transmission shaft 61 is arranged along the width direction of the body 001. The two side wheel assemblies 07 are rotatably mounted at two ends of the transmission shaft 61, respectively. The power assembly 06 simultaneously drives the two side wheel assemblies 07 to rotate through the transmission of the transmission shaft 61.
The two side wheel assemblies 07 are not in contact with the traveling surface when the body 001 is in the upright state. The side wheel assembly 07 at the left side is in contact with the traveling surface when the body 001 tilts towards the left side, to provide the body 001 with the transverse power towards the left side. The side wheel assembly 07 at the right side is in contact with the traveling surface when the body 001 tilts towards the right side, to provide the body 001 with the transverse power towards the right side.
Specifically, as shown in
The side wheel 73 and the first bevel gear 72 are fitted over the wheel shaft 71. The first bevel gear 72 and the side wheel 73 are coupled through a clearance fit between a polygonal shaft core and a polygonal shaft hole. As shown in
The power assembly 06 further includes a driving motor 63, the driving motor 63 drives the transmission shaft 61 to rotate, to drive the second bevel gears 62 at two ends to rotate synchronously, and the two second bevel gears 62 drive the two side wheels 73 to rotate around the wheel shafts 71, respectively.
In some examples, as shown in
The driving motor 63 drives the rotating gear 611 to rotate, the rotating gear 611 drives the wheel input gear 641 to rotate, the wheel input gear 641 drives the wheel output gear 642 to rotate through the wheel transmission gear 643, and the wheel output gear 642 drives the rotating gear 611 and the transmission shaft 61 to rotate, thus realizing the transmission of power from the driving motor 63 to the transmission shaft 61. A reduction ratio between the driving motor 63 and the transmission shaft 61 may be changed by changing the number of teeth of the wheel input gear 641, of the wheel output gear 642 and of the wheel transmission gear 643.

The driving wheel 03 drives the track 05 to rotate, and the track 05 drives the driven wheel 04 to rotate when the driving wheel 03 rotates.
The advance of the body 001 is realized by the track, which makes the movement of the body 001 more stable and may adapt to various sites.
The first snap portion 31/41 may be designed as a notch, the second snap portion 51 may be correspondingly designed as a snap member, and the snap member is inserted into the notch to be fitted with the notch for positioning. Alternatively, the first snap portion 31/41 may be designed as the snap member, and the second snap portion 51 may be correspondingly designed as the notch.

A driving wheel limiting shaft core 612 is fixedly provided on the transmission shaft 61. At least part of a cross section of the driving wheel limiting shaft core 612 is polygonal, and a driving wheel shaft hole 32 at a center of the driving wheel 03 is designed as a polygonal hole corresponding to the driving wheel limiting shaft core 612. The driving wheel limiting shaft core 612 is in a clearance fit with the driving wheel shaft hole 32, which is convenient for mounting and may effectively drive the driving wheel 03 to rotate.
Alternatively or additionally, the driving wheel 03 is arranged at a rear end of the body 001, and the driven wheel 04 is arranged at a front end of the body 001. The body 001 is driven from the rear end, so that the driving force is more stable.
