Description

Smart Simulator {SMART SIMULATOR}

The present invention relates to a simulator that can experience virtual reality while moving in the virtual space the same as the actual human motion.

The virtual reality simulator is configured to move the virtual reality only through specific movements such as walking, shooting posture, and hand manipulation.

The conventional virtual reality simulator has only limited operation, and there is a limit to experiencing a realistic experience in a situation such as the actual ground.

SUMMARY OF THE INVENTION An object of the present invention is to provide a smart simulator that can walk, run, sit and jump in various ground environments to implement all movements while walking.

In order to achieve the above object, the present invention provides a simulator, comprising: a walking part composed of a treadmill free to rotate; A resistance generation unit which gives a resistance to the drive shaft of the walking unit and experiences walking in accordance with the relationship between the weight and the ground; A roller part which is installed at the lower end of the belt of the walking part and comprises a plurality of roller beams to minimize frictional resistance between the belt and the bottom plate; An automatic elastic damping adjustment unit capable of expressing various floor states; A safety part that is worn on the waist and can be safely used when the user uses a wearable display such as a head mounted display; An inclination adjustment unit capable of adjusting the inclination of the floor; A rotating unit configured to experience natural curved walking by rotating the system when the user is walking in a curved path; Connected to the cable of the safety section, it provides a smart simulator consisting of a position sensor that detects the user running up or down.

Here, unlike the conventional simulator that detects a human motion and is driven by a motor, the walking part adjusts the load appropriately according to the state of the ground through the adjusting action of the resistance generating unit to achieve the same effect as actually walking.

At this time, the elastic damping adjustment unit adjusts the elasticity and the damping coefficient according to the floor state of the virtual reality so as to produce a soft effect in the sand and hard on the concrete floor.

And, at this time, the safety unit to freely rotate the user's waist by fixing to enable the use of a safe simulator. At the end of the support wire connected to the safety unit, the position sensing unit is configured to detect the movement of the user sitting or running, so that various operations can be expressed.

On the other hand, there is an inclination adjustment unit can appropriately implement a variety of ground conditions, it is also possible to implement a system capable of linear walking as well as curved walking by using a rotating unit for rotating the entire system.

According to the smart simulator according to the present invention, it is possible to supply a simulator at a relatively low cost, in which the overall structure is simple but can produce the same experience effect as the actual walking and can express all the movements taken by the human at walking.

Smart simulator according to an embodiment of the present invention, as shown in Figure 1, while walking the walking unit 1 while watching the housekeeping reality appearing on the monitor is able to move into the virtual reality as the belt of the walking unit rotates.

There is a safety portion (4) for supporting the user's waist can prevent the user from falling in various situations.

As shown in Figure 2, the smart simulator according to an embodiment of the present invention is provided with an automatic elastic damping adjustment unit (3) is installed at the bottom of the walking portion, such as soil floor, concrete floor, sand floor in the virtual reality, such as when the floor state is changed Adjust the modulus of elasticity and damping to achieve the same effect as walking the bottom of a real situation. The lower portion of the walk portion (1) is provided with an inclination adjustment unit (5) consisting of a screw jack is generated in accordance with the ground state in the virtual reality can maximize the movement effect. Referring to FIG. 2, a screw jack according to an embodiment may be positioned between a flat plate and a rotating part and may generate a slope according to a ground state by elevating and adjusting a front end of the walking part.

As shown in FIG. 3, there is a resistance generation unit 2 on one of the rotating shafts of the walking unit 1, so that a person actually generates a resistance to spur off the ground. In the early stage of walking operation, less resistance is generated and when walking is made in earnest, the resistance is increased so that the operation of the smart simulator and the actual walking operation are performed smoothly. The lower part of the smart simulator is provided with a rotating part 6 consisting of a worm and a worm wheel. When the user walks, the rotation sensing system configured in the safety part 4 operates to rotate the whole system in the direction in which the user rotates to walk linearly. In addition, rotational walking is possible.

As shown in FIG. 5, the position detecting unit 7 connected to the safety unit has a rotation sensor therein, which rotates the entire system as the user rotates, and detects this operation when the user sits or runs and interworks with the virtual reality. Make it work.

As shown in FIG. 7, the automatic elastic damping adjusting unit 3 includes a cam 8 and a motor 11 including an elastic damping unit composed of a damper 10 in the form of a damping block formed of a spring 9 and an elastic material such as rubber. By adjusting the space inside the elastic attenuation part, the elastic modulus and the damping coefficient can be adjusted according to the various floor states appearing in the virtual reality.

As shown in FIG. 8, the smart simulator may wear and use a head mounted display 12.

As shown in FIG. 9, a roller 13 is provided between the belt and the bottom plate of the walking part 1 to minimize the resistance between the belt and the bottom plate so that the driving resistance of the belt is transferred to the resistance generation part 2. Control only by
