Description

{AIR-CUSHION VEHICLE FOR AMUSEMENT}

More particularly, the present invention relates to an air play apparatus for a child who can safely ride and enjoy at high speed, a propeller rotatably mounted inside the housing, capable of rapid braking, This is a technology related to air suspension.

It is also known as HoverCraft in the name of Britain's Hovercraft, the first of its kind to develop this airfoil, and it produces air cushions by blowing compressed air to the surface of the water from the lower surface of the hull, Refers to a vessel that supports weight and floats slightly from the surface of the water.

Even if the bottom part of the ship of general shape blows air toward the sea surface, the hull levitation effect is small. Therefore, the air suspension hangs the skirt made of rubber or the like around the hull to the surface of the water, and floats the hull by preventing the compressed air blown out.

The hovercraft is relatively easy to obtain at high speed because the resistance of the hovercraft when the hull is raised is significantly smaller than that of a normal ship.

In addition, due to the floating nature of the air floating pillow, it has an advantage that it can run all over the ground such as sleeping pond, puddle, similar, and ice sheets. Therefore, hovercraft is used for various purposes such as civilian use and military use.

In recent years, designs and products have been emerging that allow individuals to ride and enjoy airplane miniaturization.

However, there is a problem in that braking is difficult because the air floating jets travel in a floated state on the ground and water surface, and a propeller projected to obtain driving propulsive force is provided, so that the body can be injured if it touches the body.

In addition, when the children carry the air-lifting device directly, they can not be relieved from the risk of accident because the range of movement is not restricted.

Patent Document 10-2013-0119370: Remote control lifting hovercraft

Accordingly, the present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a propeller which can be safely ridden and enjoyed at high speed by a propeller built in the inside of the housing, And an object of the present invention is to provide an air suspension for play which can be limited.

Technical Solution According to an aspect of the present invention, there is provided an air conditioner for a play, the air conditioner comprising: a housing having a plurality of exhaust holes penetrating downward; A lift device installed inside the exhaust hole to lift up the housing and to send air downward; A skirt having an upper portion fixed to the housing and a lower portion slidable downward to confine the air sent from the lifter to the space between the housing and the ground; A control unit for controlling driving of the lifting unit; A traveling input unit electrically coupled to the control unit to receive a traveling control from a user aboard the housing; And a power unit for supplying power to the lifter and the control unit, wherein at least one of the lifters rotates in a direction different from that of the other lifter.

In addition, the plurality of exhaust holes may be formed on all sides of the housing, and one of the lifters may rotate in the same direction as another lifter located diagonally with respect to the center of the housing.

A gyro sensor electrically coupled to the control unit to detect a tilting degree of the housing; The braking device according to any one of claims 1 to 3, further comprising: a braking unit coupled to the lower portion of the housing to stop the movement of the housing, wherein the controller detects that the braking operation is performed when the tilting angle of the housing detected by the gyro sensor And lowering the temperature.

The apparatus may further include a movement path storage unit coupled to the gyro sensor and the controller to store a traveling path of the housing.

The apparatus may further comprise a travel range setter disposed on the ground to define a movable area of the housing and in wireless communication with the control section, wherein the housing moves out of the movable range or wireless communication with the travel range setter The control unit controls the driving of the lifting unit such that the housing moves to a return position stored in the traveling path storing unit.

The remote controller may further include a remote controller connected to the travel range setter in a wired or wireless manner to control traveling of the housing at a remote place instead of the travel input unit.

The power supply unit may further include a power remaining amount detector for monitoring a remaining power amount of the power supply unit. If the power remaining amount of the power supply unit is less than a predetermined level, the control unit causes the housing to move to the return position, And controlling the driving of the lifting device.

The GPS module further includes a GPS module that acquires three-dimensional coordinates of the position of the housing and stores the three-dimensional coordinates in the movement path storage unit.

Further, the upper portion of the skirt is fixed around the side of the housing, and is expanded on the side of the housing when the lifter is driven.

According to the above-described play-by-play air conditioner,

First, it becomes possible to move the air lift forward and backward, leftward and rightward, and diagonal by the lifter disposed on all four sides of the housing.

Second, since the positive rotation of the air levitation uses the recoil torque of the lifting device, it becomes possible to rotate in place.

Third, since the lifting devices are all installed inside the housing, there is no fear that the young children will be injured by the rotating propeller.

Fourth, since all of the plurality of lifting devices send air downward to float the housing, it is possible to configure the motors installed in each lifting device to have lower specifications than the general air lifting information.

Fifth, when the lifting device is driven, the skirt is expanded toward the side of the housing, so that the impact transmitted to the occupant is alleviated even if a collision occurs.

Sixth, it is possible to prevent a safety accident in a ramp by providing a brake capable of braking an air-fueled vehicle.

Seventh, since the air lifting movement route is stored in the travel route storing unit, it is possible to return to the safe place by moving back the travel route, and the air lifting jig can be automatically caused to travel along the stored travel route.

Eighth, the remaining power detector monitors the remaining power of the power source and outputs a warning signal to the occupant when the remaining power level is less than a certain level, or forwards the air suspension to a safe place, .

Ninth, because the range-of-movement adjuster can limit the range of air-levitation movements, it is possible for a child to use the air-lifts only in a safe position, even when the guard does not monitor them.

In the tenth, since the remote controller communicates with the travel range setting device capable of long distance radio communication with the air lift type, it controls the air float, so that the traveling of the housing can be controlled from a remote place even with a smart phone having a relatively short wireless communication range.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 3, a play air vending machine 100 according to an embodiment of the present invention includes a housing 110 having a plurality of exhaust holes 116 penetrating downwardly, a housing 110, A lifting unit 120 installed inside the exhaust hole 116 for lifting up the lifting unit 120 and delivering air downward and a lifting unit 120 for lifting the upper portion of the housing 110 to confine the air sent from the lifting unit 120 between the housing 110 and the ground. A control unit 150 for controlling the driving of the lifting unit 120 and a control unit 150 for controlling the driving of the lifting unit 120. The control unit 150 controls the driving of the lifting unit 120, A power input unit 162 electrically connected to the controller 150 and a power unit 170 for supplying power to the lifter 120 and the controller 150.

In particular, as shown in FIG. 1, at least one of the lifting devices 120 has a feature of rotating in a different direction from the other lifting devices 120.

In the middle of the upper portion of the housing 110, a cockpit 112 on which a user can ride is formed. In the cockpit 112, a seat 113 and a seat belt 114 . It is preferable that the travel input unit 162 is disposed on the front side of the seat 113 so that the user can ride on the cockpit 112.

The travel input unit 162 is a type of human interface that can be operated by a user who is aboard the housing 110 and can be implemented by a handle, a joystick, a game pad, or the like.

The housing 110 may be made of a structure or material suspended from water so that the air lift 100 does not sink into the water even if the lifting unit 120 stops due to an unexpected failure during traveling on the water surface .

The lifter 120 discharges air to the lower side of the housing 110 to compress the air between the housing 110 and the ground to float the housing 110 from the ground to a predetermined height.

In particular, the lifting device 120 is installed inside a plurality of exhaust holes 116 formed in the four sides of the housing 110, respectively.

2A and 2B, the lifter 120 includes an electric motor 121 generating a rotational power when power is supplied thereto, a propeller 123 coupled to the rotational shaft of the electric motor 121 and generating wind when the electric motor 121 rotates, And a fixed frame 122 fixed to the housing 110 to fix the electric motor 121 on the exhaust hole 116 of the housing 110.

In order for the suspended air lifting body 100 to advance, the rear lifting unit 120 rotates more quickly than the front lifting unit 120 to tilt the housing 110 forward. Further, at the time of the backward movement, the lifter 120 located at the front rotates more quickly and tilts the housing 110 backward. When the housing 110 is tilted, more air is blown out in the opposite direction and the housing 110 is moved. With this principle, it is possible to move the air suspension 100 also diagonally to the right and left.

Further, when the motor 121 is driven to rotate the air suspension 100, a reaction torque acting in a direction opposite to the direction of rotation of the rotation shaft is used.

 One of the plurality of lifting devices 120 rotates in the same direction as the other lifting device 120 located diagonally with respect to the center of the housing 110 and the lifting device 120 In the direction opposite to the direction of rotation.

1, the first lifter 120a located on the front left side of the housing 110 and the fourth lifter 120d located on the rear right side of the housing 110 of the lifter 120 are the same And the second lifter 120b located on the front right side of the housing 110 and the third lifter 120c located on the rear left side of the housing 110 rotate in the same direction and the first lifter 120a and the second lifter 120b rotate in opposite directions to each other.

Although the lifting devices 120 are rotated in opposite directions, it is the same that the air is delivered to the lower side of the housing 110.

When all the lifters 120 rotate at the same speed, the backlash torque generated in each lifter 120 is canceled by the other lifter 120 rotating in the opposite direction. However, when only the rotational speeds of the lifting devices 120 rotating in any one direction are increased, the backward torque acting as the opposite eccentricity increases, and the air lifting device 100 is rotated in the rotational direction of the lifter 120 As shown in FIG. That is, to rotate the air cylinder 100 in the clockwise direction, the second lifter 120b and the third lifter 120c that rotate in the counterclockwise direction rotate faster than the other lifters 120a and 120d The first lifter 120a and the fourth lifter 120d that rotate in the clockwise direction rotate faster than the other lifters 120b and 120c in order to rotate the air lifter 100 in the counterclockwise direction.

If the plurality of lifters 120 are all rotated in the same direction, the rebound torque of the lifter 120 is biased in only one direction, so that the air lift 100 will continue to rotate.

For safety, a safety net 118 (see FIG. 5) is preferably provided on the upper and lower sides of the exhaust hole 116 to block entry of the body and foreign matter.

The embodiment of the present invention can omit a propelling rotor for sending air backward to travel a general air suspension, and it is possible for the air suspension 100 to rotate in place. In addition, since all the lifting devices 120 are installed inside the housing 110, there is no fear that the young children are injured by the rotating propeller 123, and all the lifting devices 120 float the housing 110 It is possible to configure the motor 121 provided in each lifter 120 to have a lower specification than the general air suspension 100. [

The skirt 130 is configured to confine the air delivered to the lower side of the housing 110 through the lifter 120 between the lower portion of the housing 110 and the ground.

The skirt 130 is fixed tightly around the housing 110 only with the bottom opened.

The lower portion of the skirt 130, which is opened to the ground, is in contact with the ground so that the air sent to the lower portion of the housing 110 is not discharged, and the air between the lower portion of the housing 110 and the ground is compressed. The compressed air pushes the bottom of the housing 110 and the inside of the skirt 130 including the ground, and the pushing force causes the housing 110 to float.

Since the lower portion of the skirt 130 is opened, some of the compressed air is discharged through the gap formed between the skirt 130 and the ground. However, since the air is delivered from the lifter 120 to the lower portion of the housing 110, Air is kept at a certain level.

Since the skirt 130 is fixed to the periphery of the housing 110, when the lifting unit 120 is driven and the air is delivered to the lower portion of the housing 110, the compressed air pushes the inner surface of the skirt 130 And is inflated on the side of the housing 110. Even when the airbag 100 collides against the wall surface or the structure during traveling due to the inflated skirt 130 on the side of the housing 110, the collision impact is mitigated and transmitted to the user who rides the airbag 100, thereby preventing injury.

The control unit 150 controls the driving of the air lift 100 through the driving control of the lifting unit 120. [ The control unit 150 controls the operation of the lift unit 160 based on the driving control signal input by the user on the housing 110 to the driving input unit 162 and the signal from the remote controller 164 and the driving range setting unit 200, (120).

It is preferable to further include a communicator 154 coupled to the controller 150 to be wirelessly connected to the remote controller 164 and the travel range setter 200.

The power supply unit 170 supplies power to all the electronic configurations provided in the housing 110 of the air suspension 100 including the control unit 150 and the lifting unit 120.

In order to drive the lifter 120 for a long time, the power supply unit 170 is preferably configured as a rechargeable secondary battery that does not need to be replaced.

If the lifting device 120 is stopped due to the exhaustion of power during the operation of the air lifting device 100 on the water surface, the user who rides on the housing 110 drifts together with the air lifting device 100. In order to prevent such a situation, a power remaining amount detector 172 is coupled to the power source unit 170 to monitor the remaining power level of the power source unit 170 in real time while the air suspension 100 travels.

The power remaining amount monitored by the power remaining amount detector 172 is transmitted to the control unit 150. The control unit 150 outputs a warning signal to the user when the remaining power of the power unit 170 is less than a predetermined level, 100) to a safe place to protect the user.

Since the airbag 100 floats on the ground at a predetermined height, braking is not easy. Particularly, when the airbag 100 running on the ground enters the ramp, it may fall rapidly along the ramp to cause an accident.

The air suspension 100 includes a gyro sensor 152 electrically coupled to the controller 150 to detect the degree of tilting of the housing 110 and a housing 110 for stopping the movement of the housing 110. [ And a brake 140 which is movably coupled to a lower portion of the vehicle.

The gyro sensor 152 is a sensor capable of detecting a three-dimensional attitude, and is installed in the housing 110 to detect a direction in which the housing 110 is oriented and an inclined angle. 2B, when the inclination angle of the housing 110 detected by the gyro sensor 152 is equal to or greater than the limit angle set in the controller 150, the controller 150 moves the brake 140 downward, So that the air-bearing surface 100 is stopped.

The limit angle is a value preset in the controller 150 and is preferably set to an irreversible tilt angle of the output of the lifting device 120 of the air suspension 100. For example, The controller 150 descends the brake 140 when the posture of the housing is maintained for a predetermined time in a state where the posture of the housing is inclined beyond a limit angle in any direction.

The values of the attitude of the housing 110 detected by the gyro sensor 152 may be controlled by controlling the lifting device 120 of the controller 150 to balance the housing 110 suspended by the lifting devices 120. [ So that stable travel can be performed.

2B, the brake 140 is lowered from the housing 110 and comes into contact with the ground, thereby braking the housing 110. The brake 140 for this operation is constituted by a foot which comes into contact with the ground and an ascending and descending means which is fixed to the lower portion of the housing 110 to move the foot plate up and down from the housing 110. The foot plate may be a rubber plate having a concavo-convex portion formed at the bottom thereof to improve frictional force. The foot plate may be composed of a motor driven by receiving power from the control unit 150 and coupled with a foot plate and a gear. (A structural feature relating to the brake 140 is related to a general braking device and a detailed description will be given)

The embodiment of the present invention also includes a movement route storage unit 151 coupled with the gyro sensor 152 and the control unit 150 to store the traveling route of the housing 110.

The movement path storage unit 151 may store the posture value and the time of the housing 110 detected by the gyro sensor 152 and the driving speed of the lifting unit 120 to estimate the movement path of the housing 110 It is used as information. This movement path may be used to return to a safe place when the remaining power level of the air suspension 100 is less than a predetermined level and may cause the air suspension 100 to automatically travel along the stored movement route.

The movement path storage unit 151 preferably stores the attitude values of the housing 110 detected by the gyro sensor 152 and represented by numerals, and is preferably composed of a flash memory and coupled to the controller 150.

In order to store the position of the housing 110 more accurately in the movement route storage unit 151, a GPS module for obtaining three-dimensional coordinates of the position of the housing 110 and storing the three- 153).

When the coordinate value of the position where the operation of the air suspension 100 is started by the GPS module 153 is stored in the movement route storage unit 151, the air suspension 100 such as a situation where the power source is insufficient needs to return to the safe position The GPS coordinate value at the current position may be compared with the coordinate value of the travel start position stored in the movement route storage unit 151 so that the air lift 100 immediately moves to the start position.

In order to safely use the airbag 100 even in a situation in which the guard does not monitor, the child range setting device 200 further includes a travel range setting device 200 that defines a movable area of the housing 110, as shown in FIG.

The controller 150 controls the operation of the driving range setting device 200 so that the housing 110 travels only within the movable range of the moving range setting device 200 And controls the driving of the lifting device 120 so that the lifting device 120 is driven.

If the housing 110 is out of the movable range of the travel range setting device 200 or if the power supply of the power supply unit 170 is less than a certain level after the wireless communication is cut off or the power supply unit 170 is under a certain amount, And controls the driving of the lifter 120 to move the housing 110 to the pre-stored return position.

When the return position is not specifically set, the position may be the position of the travel range setting device 200 or the position where wireless communication with the travel range setting device 200 can be performed. However, It may be the position of the coordinate value.

The travel range setter 200 may be connected to the communicator 154 through a wireless communication method such as Wi-Fi, Bluetooth, ZigBee, or the like.

The setting of the movable area may be set by the travel range setting device 200, but may also be set by the control part 150. [

The travel range setter 200 includes communication means (not shown) for performing long-range wireless communication with the communicator 154 and a power source device (not shown) for supplying power to the communication means, But may be implemented in the form of a flat dish so that the housing 110 that travels can move without hitching upward.

Also, as shown in FIG. 5, a remote controller 164 for wirelessly communicating with the travel range setter 200 to directly control the running of the air lift 100 at a remote place by a guardian of a child is included.

The remote controller 164 is connected to the travel range setter 200 via wired or wireless lines and is transmitted through the travel range setter 200 in which a control signal of the remote controller 164 is capable of long distance wireless communication with the controller 150. Therefore, even in a smartphone having a relatively short wireless communication coverage, traveling of the housing 110 can be controlled from a remote place.

Also, the remote controller 164 may be implemented as a controller connected to the travel range setter 200 by wire.

Next, an example of using the play air suspension 100 according to the embodiment of the invention will be described.

First, the travel range setter 200 is disposed at a position where the protector will be a reference of the movable range of the housing 110.

The child then rides in the cockpit 112 of the housing 110 to drive the lifter 120 to cause the housing 110 to float on the ground.

The driving of the housing 110 can be directly controlled by the child through the driving input portion 162 or the remote control can be controlled by the protector remote from the remote controller 164.

If the housing 110 enters the ramp, the brake 140 is lowered and the housing 110 is braked.

When the traveling housing 110 is out of the movable range, the controller 150 interrupts the control signal input of the traveling input unit 162 and automatically moves the housing 110 to the return position.

Also, when the remaining power of the power source unit 170 becomes less than a preset level, the controller 150 outputs a warning signal indicating that the remaining power source is insufficient, and moves the housing 110 to the pre-stored return position.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It is clear that the present invention can be suitably modified and applied in the same manner. Therefore, the above description does not limit the scope of the present invention, which is defined by the limitations of the following claims.
