The present invention relates to a haptic feedback device, and more particularly to a haptic feedback device for steering simulation with improved wheel slip effect.
In electronic game arcades, haptic feedback arcade games are popular with players, because they can interact with players and offer exercise feedback player can experience virtual reality, which makes haptic feedback arcade games welcomed. Besides, in large amusement parks, haptic feedback recreational facilities are always popular and full of people.
Motorcycle companies with well initial development produce racing training simulators for simulating the body actual motion while riding. In addition, the movement of motorcycle is presented by three degrees of freedom: roll, pitch, and yaw.

In the aforementioned riding simulation system, the roll movement is constructed by the motor 17, the pitch movement is constructed by the movable carriage 2, and the yaw movement is constructed by the slide member 7, so that the actual riding experience can be simulated for training.
Please refer to
The multiple haptic feedback technique is disclosed by the prior arts, but its center line of roll is disposed below or in the center of the model motorcycle, so that the model motorcycle can only swing or lean in rightward or leftward directions. When rotating around the rotation center line to perform cylindrical rotation, if the model motorcycle simulates multiple motions, plural actuators are required, and haptic feedback system will become more complicate.
However, certain problems exist in the current device and system:
1. Less Realistic Haptic Feedback
In the motorcycle gaming device, it has rolling mechanism to move the motorcycle body, so wheel slip motion can be simulated, but rolling the motorcycle body is lack of outward slip effect, and haptic feedback is not realistic enough.
2. Wasting More Energy
The swing structure in the conventional motorcycle gaming device is located below the motorcycle body, so the body center of gravity is higher, no matter the motorcycle body is driven by feet or motor, more energy is wasted for supporting a higher center.
3. Complicate Mechanism Structure
In prior art system, the slide member can control the side slip of rear wheel to simulate yaw movement. However, if more realistic slip or other haptic feedback is required, more actuators are required for stimulating roll, pitch and yaw movements, and the mechanism structure will become relatively complicate.
Therefore, developing a mechanism structure with less power components to simulate various haptic feedback which can applied to other haptic feedback recreational facilities is the objective those in the field are seeking to achieve.
Therefore, an objective of an embodiment of the present invention is to provide a haptic feedback device, comprising a base unit and a rolling unit.
The base unit includes a base, a base supporting body extended upward from the base, a first rolling component located on the base, and a second rolling component located on top of the base supporting body. A roll center line is formed by the first and the second rolling components.
The rolling unit includes a rolling base being capable of carrying at least one person, and a rolling supporting body connected to the rolling base. One part of the rolling base is pivotally connected to the first rolling component, and one part of the rolling supporting body is pivotally connected to the second rolling component, so that the rolling base can rotate around the roll center line and a cone rotation can be performed.
Another technique of an embodiment of the present invention is that the first and the second rolling components are respective bearings, and the roll center of the first and the second rolling components is aligned with the roll center line.
Another technique of an embodiment of the present invention is that height of the first component is lower than the second rolling component.
Another technique of an embodiment of the present invention is that the rolling unit further includes a rotating power component being capable of rotating the rolling base.
Another technique of an embodiment of the present invention is that the rolling supporting body is provided with a length-adjustable actuation component to control the length of rolling supporting body.
Another technique of an embodiment of the present invention is that the rolling unit further includes a first joint component disposed between the first rolling component and the rolling base, a second joint component disposed between the second rolling component and the rolling supporting body, and a third joint component disposed between the rolling base and the rolling supporting body.
Another technique of an embodiment of the present invention is that the rolling supporting body is provided with a first rolling supporting shaft connected to the second rolling component, and a second rolling supporting shaft connected to the third joint component. The rolling unit further includes a fourth joint component disposed between the first and the second rolling supporting shafts.
Another technique of an embodiment of the present invention is that a carrying component being capable of carrying a person is disposed on the rolling base, which is selected from a set consisting of standing platform, standard seat, straddle seat, supine-position platform, and prone-position platform.
Another technique of an embodiment of the present invention is that the present invention further includes a motorcycle gaming unit, a motorcycle controlling component disposed on the rolling base, a game controlling component electrically connected to the motorcycle controlling component, and a game display component electrically connected to the game controlling component. A controlling order can be sent to the game controlling component by the motorcycle controlling component, so that the game controlling component can control the rotating power component, the actuation component and the game display component.
Another technique of an embodiment of the present invention is that the present invention further includes a haptic feedback unit, which includes a haptic feedback controlling component installed with a haptic feedback program, and an image display component electrically connected to the haptic feedback controlling component. When the haptic feedback program is executed by the haptic feedback controlling component, the rotating power component, the actuation component and the image display component can be controlled.
Another technique of an embodiment of the present invention is that the present invention further comprises a slip gaming unit, which includes an angle detecting part being capable of detecting the rotating angle of the rolling base, a game controlling component electrically connected to the angle detecting part, and a game display component electrically connected to the game controlling component. When the game controlling component executes a game program, and receives the angle information detected by the angle detecting part, the rotating power component, the actuation component and the game display component can be controlled.
An advantage of embodiments of the invention is that the rolling base uses the first rolling component as a cone apex, and uses the rotating center line as center, a cone pendulum or rotation can be performed. When the rolling base driven by the rotating power component swings around in a cone pendulum, the centrifugal effect of motorcycle leaning motion can be simulated, such a like roll, pitch and yaw movement. The conventional motorcycle simulating devices use plural motors to simulate the actual steering operation of motorcycle, and the present invention can effectively reduce the amount of motors.
The actuation component can control one part of the rolling base to move outward, so that actual riding slip situation can be simulated, and is more realistic than the conventional rotating motorcycle carriage technique. Besides, the present invention can be applied to large haptic feedback cabin, and when the rolling base is rotated to the top by the rotating power component, diving motion can be simulated.

The base unit 3 includes a base 31, a base supporting body 32 extended upward from the base 31, a first rolling component 33 located on the base 31, and a second rolling component 34 located on top of the base supporting body 32.
The first rolling component 33 is separated from base supporting body 32 in a certain interval, and a roll center line 35 is formed by the first and the second rolling components 33, 34.
The rolling unit 4 includes a rolling base 41 being capable of carrying the person A, and a rolling supporting body 42 connected to the rolling base 41. One part of the rolling base 41 is pivotally connected to the first rolling component 33, and one part of the rolling supporting body 42 is pivotally connected to the second rolling component 34, so that the rolling base 41 can rotate around the roll center line 35 and a cone rotation can be performed. In addition, the person A sitting on the rolling base 41 faces the first rolling component 33.
The first and the second rolling components 33, 34 are bearings of the rolling unit 4. In this case, the first and the second rolling component 33, 34 can be apertures formed on the base 31 and the base supporting body 32, and so should not be construed as limiting the invention.
The roll center of the first and the second rolling components 33, 34 is aligned with the roll center line 35, and the roll center of the first and the second rolling components 33, 34 is the roll center line 35, so that the rolling unit 4 can rotate around the roll center line 35 smoothly. Moreover, the rolling base 41 can rotate around the roll center line 35 and a cone rotation can be performed.
The cone image depicted herein is a conical surface of a conical cylinder which is a three-dimensional geometric shape that tapers smoothly from a flat circle to a point.

Preferably, the motorcycle seat can be located on the rolling base 41, so that the person A can sit astride the rolling base 41. Force can be applied to the base 31 or the ground by the person A's feet, so that the rolling base 41 can rotate around the first rolling component 22 presented as a cone apex to perform a cone rotation. In this case, height of the first rolling component 33 is lower than the second rolling component 34, so that when the rolling base 41 is rotating, the actual knee down motion can be simulated. In addition, when the rolling base 41 is rotating, the roll, pitch and yaw motion can also be simulated.
The first preferred embodiment can be applied to the steering control in the current racing game, so that the motorcycle direction in the game can be controlled by swinging the motorcycle body.

The controlling technique in racing game is already applied to various gaming systems, and so details related to this are not explained further herein. In this case, a three-dimensional environment can be displayed by a head mount display and virtual reality technology which can offer the users a realistic visual experience, so that they can observe the objects in three-dimensional environment directly.
In the first preferred embodiment, the motorcycle body is heading toward the first rolling component 33, and the motorcycle seat is horizontally placed, when the person A swings the rolling base 41 by feet, the steering or knee down movement can be simulated. Compare to the leaning controlling technique in the conventional racing game, the haptic feedback effect of operation presented to the person A is added in the present invention.
The axle mechanism for tilt in conventional racing games is located below the motorcycle body, and the roll center is high, so much force is required to move back the leaned body by the person A.
The roll center of rolling base 41 in the first preferred embodiment is located different in response to motorcycle structure, but the rolling base 41 rotates around the roll center line 35 to perform a cone rotation, and the roll center of the rolling base 41 moves closer to the roll center line 35, so that the person A can swing the rolling base 41 with less force, and can efficiently spend less energy.
