Chapter 1, system outline

Shown in the general frame of this system such as Fig. 1 (system overall framework figure), wherein each lattice is a mould group, There are the rotor of 25 similar spin in totally 150 mould groups, each mould group the inside.

The design principle of this system is that user's foot steps down on one group of spheroidal ball of class, when the sliding friction of ball When power is smaller, user may feel that skidding, he needs to move to get up just to be able to maintain balance with cracking speed.Work as rolling When the force of sliding friction of pearl is bigger, user can use in low speed keep balance.This frictional force of reasonable utilization, Such a treadmill without power supply power supply may be implemented in we.

This system move ball can with transverse direction and longitudinal direction both direction using the ball of similar ellipse.Laterally Movement is 0 fricting movement, and longitudinal movement is resistant fricting movement.Multiple groups ball cross arrangement, when user's longitudinal movement When, the ball of longitudinal arrangement plays a role, and makes user's longitudinal movement, transversely arranged ball freely rolls, not to user It has an impact；Similarly, when user's transverse movement, transversely arranged ball generation effect, and the ball of longitudinal arrangement does not produce It is raw to influence；When user needs oblique movement, according to the decomposition principle of strength, user needs to pay more 0.5 times of strength Effect can be reached.If ball is smaller, user feels more natural.

In order to allow user's comfortable foot feeling, the size design of ball is smaller, and the ball module of this system design is 100cm ^2, each module are 25 balls.By taking 38 yards of shoes as an example, the area of a shoes is about 200cm^2, can cover about 50 rollings Pearl；Height about 2mm ~ 4mm of the prominent basal plane of each ball, since sport footwear has certain elasticity, user's fundamental sensation is not To sole injustice.

Specifically, being below column with a ball module, its design, composition and motion mode is discussed in detail.

The core of this system is using the rotor of three balls superposition, which can be using X-axis as rotary shaft, in YZ plane Upper free non-resistance rotation, and the resistant rotation (using Y-axis as rotary shaft) in XZ plane, resistance is from damping layer.When User moves forwards, backwards, sole and friction rotor, and rotor is driven to rotate in XZ plane.Fig. 2 (rotor schematic diagram) is drawn out The rotor schematic diagram of one 200 times of amplification.

User's foot steps down on rotor, rearward exerts a force, and is travelled forward by reaction strength.

1. then user moves in situ always when the strength that the movement that the resistance of rotor is equal to user is advanced.

2. applying strength when the resistance of rotor is greater than user, then user obtains positive reaction force, so that user can be to Preceding movement.

3. then user obtains negative reaction force, thus user's energy when the strength that the movement that resistance is less than user is advanced It moves backward.

Specifically, our this treadmill can dispose fixed plate in start-up portion, then it is larger to install resistance by about 20cm Rotor mould group, user's low-speed motion, or accelerate advance；Resistance rotor mould group appropriate is installed in middle position, is used Person can keep middling speed to move herein, and when speed gradually reduces, sole has the feeling of skidding, can gradually recede into low regime, and When speed raising, high velocity can be entered；In the rear end of treadmill, the small rotor mould group of resistance is installed, user enters the region, Faster speed must be kept, intermediate region otherwise will be dragged into.

Chapter 2, the design of rotor

The structure of rotor is superposition such as Fig. 3 (rotor structure exemplary diagram 1) that one big ball adds two hemisphere, wherein big ball is straight Diameter is 10mm, the small ball's diameter 5mm.

Rotor is also possible to a big ball, respectively has the spherical crown protrusion of 2mm at the both ends of ball, the radius of spherical crown should be less than big The radius of a ball at least 2mm.Such as Fig. 4 (rotor structure exemplary diagram 2)

Rotor can be moved upwards two kinds of sides.Reference axis as shown in Figure 3, definition horizontal direction are X-axis, front-rear direction For Y-axis, vertical direction is Z axis, then rotor can be rolled around X-axis, can also be rolled around Y-axis.

When the longitudinal direction of rotor is applied some strength, then rotor is rolled around X-axis, and rotor is equivalent to sphere, in spherical cavity Interior free movement, hardly by drag effects.

When the transverse direction of rotor is applied some strength, then rotor is rolled around Y-axis, and rotor is equivalent to spheroid, and the half of both ends The resistant layer of club and lower section rubs, and generates corresponding frictional force.Fig. 5 (rotor moves schematic diagram around Y-axis) display then turns The effect that son is rolled around Y-axis.

In no external force, rotor is in a horizontal position.

Chapter 3, the design of pivoted housing

Pivoted housing is the cube without upper cover, package rotor use, by shell, spherical pit pivoted housing, elliposoidal pivoted housing, 4 part such as spring, gasket composition, shown in Fig. 6 (structural schematic diagram of pivoted housing).

Wherein, shell surface B, is equipped with spherical pit pivoted housing, and the diameter in ball hole is identical as the big bulb diameter of rotor.Equally in B Also there is same spherical pit pivoted housing on the opposite (face D) in face.To which rotor can be in the spherical hole that the face BD is formed around X-axis freedom Rotation.

The face bottom case C is equipped with elliposoidal pivoted housing, and the major diameter of ellipsoid and the major diameter of rotor are identical, but the minor axis of ellipsoid is greater than Equal to the diameter of the big ball of rotor, less than the major diameter of rotor.Several springs are installed below ellipsoidal surface, it is crowded for generating Pressure, to generate frictional force.It is transferred to ellipsoid hole the inside end to end when rotor, squeezes spring, generates friction with ellipsoid pivoted housing, produce Raw resistance.

The height of bottom gasket is adjusted, different pressure can be presented in groups of springs, so as to generate different resistances,

On the face A of shell and its opposite, it is only necessary to a thin layer of protective layer.

Fig. 7 (the integral perspective effect picture of monomer) illustrates the integral perspective effect picture of monomer,

Specifically, design drawing such as Fig. 8 (design drawing of spherical shape hole set) of spherical hole set, right part of flg is perspective effect figure

Specifically, shown in design drawing such as Fig. 9 (elliposoidal hole set figure) of elliposoidal hole set.Wherein, the height of adjusting gasket, Intermediate groups of springs can produce different drags.Inside the head movement to elliposoidal pit of rotor, different power is needed Amount can just be such that rotor rolls.

Chapter 4, the design of mould group

Each module is made of a pivoted housing and rotor, and the area of each module is about 20*20mm.By 25 module spliceds At a square, wherein it is longitudinal to be arranged with lateral cross, such as Figure 10 (structure chart of mould group), form the mould of 100*100mm Group.

When user is in longitudinal movement, the column of A/C two generate frictional resistance, and B/D two arranges free rolling, without hindrance.

When user is in transverse movement, the column of B/D two generate frictional resistance, and A/C two arranges free rolling, without hindrance.

Chapter 5, the construction of entirety treadmill

On a long 1500mm, the treadmill frame of wide 1000mm, by every 200mm place fixed frame, by mould group according to It is secondary to be fixed on fixed frame, in this way, omnidirectional's treadmill is just built up.As shown in Figure 1.

By placing the module of different resistances, can play the role of adjusting movement velocity.

In general, in lateral first group, the module of low two groups of placement high-drags, third group to the 5th group of placement higher drag Module, the 6th group to the tenth group medium resistance module of placement, the 11st group to the 15th group placement low-resistance power module.

When two such treadmills are placed side by side together, just the wide cut treadmill of composition 1500mm*2000mm, is adjusted Resistance module reduces the resistance of edge module, in this way, need to keep fair speed, or retract when user is moved to edge Intermediate region.User can both be moved left and right with transverse movement, realization, can also be realized and be moved forward and backward with longitudinal movement, perfect right The motor pattern of game role is answered.

Chapter 6, the acquisition of kinematic parameter

For needing to obtain the parameters such as moving direction, movement speed in AR/VR game.

Moving direction can be obtained by three-axis gyroscope, in general, three-axis gyroscope can other Intelligent bracelets, mobile phone, In game station.

The acquisition of movement speed is somewhat difficult.Because user for treadmill, is to have very big movement speed, But for other stationary bodies, movement speed is almost 0.It, can be each more rationally to get movement speed Weight sensor is installed below mould group, by detecting the weight and variable quantity that each mould group measures, and then passes through some logics Calculate the movement velocity of user.
