Description

Mechanical module type actuator and screen golf swing board using the same

Technical Field

The present invention relates to a new concept technology of ensuring reliable operability and achieving a structural simplification by actuating a mechanical golf swing plate without using a hydraulic part.

Background

In general, golf is a game in which a hole cup is provided at a distance from a predetermined distance, and a golf ball is hit with a golf club such as a driver 1 and the golf ball is hit into the hole cup, but a predetermined number of hits are made per course, wherein a golfer who completes 18 courses with the minimum number of hits obtains a win.

The golf course is composed of a tee area where a golfer initially strikes a golf ball, a hole area provided with a hole cup, and a flat fairway provided between the tee area and the hole area. In general, the inclination of the green is not serious, but various obstacles such as a grass pit, a sand pit, and a pool are provided in the fairway, and the fairway itself has a predetermined inclination. Further, the dark grass area or the periphery of the green other than the fairway has not only a predetermined inclination but also the length of the grass therearound is adjusted, and therefore, unless a ball is hit accurately toward the fairway or the green, it is difficult to hit the next ball.

Recently, in order to overcome the economy of a field, time limit, and space limit of an indoor Golf range, a Golf simulation system (Golf simulation system) that displays a flight trajectory of a golfer hitting a Golf ball in a three-dimensional image is being developed and applied.

That is, an Optical sensor (Optical sensor) for measuring dynamic information such as a speed and a flight angle of a golf ball is installed in front of a golf swing point, and a flight trajectory of the golf ball is predicted by a computer based on the dynamic information measured by the Optical sensor and displayed as a three-dimensional image on a screen installed in front of the swing point.

In this case, the stereoscopic image actually having the same foreground as the golf course is input to the computer for calculating and outputting the predicted flight path of the golf ball, so that the golfer can obtain the visual effect as if playing golf on a field golf course, and can enjoy the golf competition with the fellow. Such a golf simulation system is widely spread in the market under the name of "Screen golf".

As a prior art related to the above golf simulation system, korean patent publication No. 1712397 of the applicant of the present invention discloses a low-profile screen golf swing plate.

Unlike the conventional swing plate in which the module type actuator and the tilt cylinder are separately formed, the above-described conventional art can provide an effect of shortening the assembly process and time and improving productivity by simplifying the overall structure of the swing plate by integrating the module type and the tilt cylinder.

Disclosure of Invention

Since the above-mentioned prior art requires various hydraulic components such as a bidirectional hydraulic generator, a hydraulic cylinder, and hydraulic lines connecting them, it requires periodic after-sales service (a/S), and since mechanical energy is required to be converted into hydraulic energy, it is liable to cause a decrease in efficiency compared to direct transmission, and oil is widely affected by temperature due to its properties, and has a problem that oil itself is dirty or oxidized and its properties are liable to be changed, thereby causing inaccurate operability and a problem that the environment is dirty due to oil leakage from the connection portions such as the hydraulic lines.

Further, the integrated module type actuator and the tilt adjusting cylinder have a large size, a large weight, and a large number of components, and thus have problems of high manufacturing cost, a large footprint, and limited space when installed.

As a means for solving the above problems, an object of the present invention is to provide a technology for adjusting the inclination of a swing upper plate by lifting and lowering a tilt adjusting lifter screw screwed with a screw shaft rotated by receiving a rotational power of a motor through a gear combination.

It is still another object of the present invention to provide a technique for reducing the initial height of the tilt adjustment lifter to further reduce the overall height of the mechanical module type actuator, thereby achieving a compact structure, as the screw shaft is rotated without interference in a state in which the screw shaft is inserted into a screw shaft hiding hole formed in the tilt adjustment lifter.

Another object of the present invention is to provide a technique for maintaining an initial state of a mechanical module type actuator by automatically recognizing that a tilt adjusting lifter is in an original position when a sensor detector which moves up and down together with the tilt adjusting lifter is lowered and detected by an original position detection sensor provided on a circuit board.

The present invention provides the following effects, namely, the hydraulic part is not needed, the lifting rod is adjusted by mechanical lifting and inclining to work, thereby reducing the occurrence of after-sales service, improving the power transmission efficiency, ensuring very accurate operability and preventing the pollution of the surrounding environment caused by oil leakage.

Further, the present invention provides an effect that the motor and the tilt adjusting lifter are integrally formed into a module type, so that the entire width can be reduced to achieve miniaturization, the number of parts and the weight can be reduced to greatly reduce the manufacturing cost, and the occupied area of the module type actuator is small and is not limited by the installation space.

Further, the present invention provides an effect that the initial height of the tilt adjusting lifter is lowered to reduce the overall height of the module type actuator, thereby realizing a compact structure, and the tilt adjusting range of the swing upper plate can be extended because the vertical stroke distance is long.

Detailed Description

The technical solution of the present invention is further explained in detail by preferred embodiments.

Viewing the overall structure with reference to the drawings, the mechanical module type actuator a according to the preferred embodiment of the present invention includes a gear box 10, a motor 20, a motive gear 30, a driven gear 40, a bottom block 50, a screw shaft 60, a tilt adjusting elevating bar 70, a plurality of anti-rotation guide bars 90, and a lower plate joint 110.

The present invention having the above-described configuration will be described in further detail below so as to facilitate the practice of the present invention.

First, the gear case 10 of the present invention has a rectangular parallelepiped shape, the motor 20 for supplying rotational power to the screw shaft 60 in a forward/reverse rotatable manner is directly provided at one upper end, the motor shaft 21 of the motor 20 is rotatably inserted through the bearing 22, the bearing 22 is inserted through the upper surface of the gear case 10 into the inside and is provided at the bottom surface of the gear case 10, and the motive gear 30 is integrally coupled to the motor shaft 21 inserted into the gear case 10, whereby the motive gear 30 can be smoothly rotated inside the gear case 10.

A driven shaft 41 penetrating the other side of the upper end of the gear case 10 and entering the gear case 10 is rotatably penetrated through a pair of bearings 42 provided on the upper and bottom surfaces of the inner surface of the gear case 10, a driven gear 40 integrally coupled to the driven shaft 41 is engaged with the driving gear 30, and the rotational power of the motor 20 is transmitted to the driven shaft 41 through the gear combination of the driving gear 30 and the driven gear 40, thereby rotating the driven shaft 41 in an interlocking manner.

A plurality of spacers 51 are stacked on the other upper end of the gear case 10, the bottom block 50 is continuously stacked on the upper ends of the spacers 51, the spacers 51 and the bottom block 50 are integrally fixed to the upper end of the gear case 10 by a plurality of fasteners penetrating fastening holes 52 formed around the spacers 51 and the bottom block 50, and the driven shaft 41 is rotatably coupled to a rotation through hole 53 formed in the centers of the spacers 51 and the bottom block 50.

The screw shaft 60 is directly connected to the driven shaft 41 coaxially and integrally, and the screw shaft 60 has a structure in which a coupling shaft portion 61 directly connected to the driven shaft 41 is formed at a lower portion and a screw 62 is formed at an upper portion of the coupling shaft portion 61.

In the screw shaft 60, as the coupling boss 61 formed at the lower portion is rotatably inserted through the pair of bearings 54 provided at the upper and lower portions of the inner surface of the rotation through hole 53 formed in the bottom block 50, the driven shaft 41 is fixed to the inside of the coupling shaft 61 by a key after being inserted through the center of the coupling shaft 61, so that the screw shaft 60 and the driven shaft 41 are directly connected to each other, and the fastening nut 63 is screwed to the lower outer side of the coupling shaft 61, thereby preventing the screw shaft 60 from being separated from the driven shaft 41 due to the upward movement thereof.

A tilt adjusting elevation bar 70 is screw-coupled to an outer side of the screw shaft 60, the tilt adjusting elevation bar 70 being selectively ascended or descended according to forward/reverse rotation of the screw shaft 60, the tilt adjusting elevation bar 70 having a guide flange 71 protrudingly formed on an outer circumferential surface of a lower end thereof and being screw-coupled integrally to an upper end bar end 72.

However, in order to prevent the screw shaft 60 from rotating together with the screw shaft when rotating in the forward/reverse direction, the tilt adjusting elevating rod 70 must be maintained in a non-rotating fixed state, thereby being capable of smoothly elevating.

Therefore, in the guide flange 71, a plurality of guide holes 73 are formed to penetrate vertically in a radial shape, a plurality of rotation preventing guide rods 90 for guiding the vertical movement of the tilt adjusting lifter 70 are coupled to each other through the guide holes 73 formed to penetrate vertically in the guide flange 71, the lower sides of the plurality of rotation preventing guide rods 90 are integrally fitted to and coupled to coupling grooves 55 formed in the circumferential direction on the upper surface of the bottom block 50, and the upper sides thereof are integrally fitted to and coupled to coupling grooves 85 formed in the circumferential direction on the lower surface of the top block 80 fitted to the outer side of the upper portion of the tilt adjusting lifter 70.

Therefore, when the screw shaft 60 is rotated in the forward/reverse direction, the tilt adjustment lifter 70 is smoothly raised or lowered in a non-rotating state as the guide flange 71 is moved up and down along the rotation preventing guide rod 90.

The upper and lower sides of the external cylinder 91 are integrally fitted and coupled to the outer circumferential surfaces of the bottom block 50 and the top block 80, thereby preventing the tilt adjusting lift rod 70 and the rotation preventing guide rod 90 from being exposed to the outside, and preventing foreign substances from flowing into a screw coupling portion between the screw shaft 60 and the tilt adjusting lift rod 70, thereby ensuring smooth operability of the tilt adjusting lift rod 70.

As shown in fig. 6, in the tilt adjusting lift lever 70, a nut press-fitting groove 74 is formed in a recessed manner in a lower inner peripheral surface, a phosphor bronze nut 75 is press-fitted into the nut press-fitting groove 74, and the screw shaft 60 is screwed only partially to the phosphor bronze nut 75 and is rotated without interference in a state of being inserted into a screw shaft hiding hole 76 communicating with an upper portion of the nut press-fitting groove 74.

Therefore, the screw shaft 60 is screwed into a short section corresponding to the length of the phosphor bronze nut 75, and a smooth lifting effect is provided to the tilt adjustment lifter 70 by reducing the rotation resistance, and the screw shaft 60 is rotated without interference in a state of being inserted into the screw shaft hiding hole 76, and the initial height of the tilt adjustment lifter 70 is reduced to further reduce the overall height of the mechanical module type actuator a, thereby realizing a more compact structure.

In order to connect the mechanical module type actuator a to the screen golf swing plate S for use, the present invention has a structure in which a lower plate joint 110 is integrally attached to a lower end of the gear case 10 by a fastener directly below the bottom block 50, and a rod end 111 is integrally formed on a lower surface of the lower plate joint 110 so as to be smoothly moved with a gap removed.

The mechanical module type actuator a of the present invention configured in this way provides effects of reducing the occurrence of after-sales service by mechanically elevating and lowering the tilt adjustment lifter 70 without using hydraulic parts, improving power transmission efficiency, making operability very accurate, and preventing pollution of the surrounding environment due to oil leakage.

The present invention also includes a technique for making the movement of the tilt adjusting lift lever 70 more smooth when it is lifted.

With this structure, the

guide bushes

77 and 82 for reducing frictional resistance are fitted into the lift rod through-holes 81 formed in the top block 80 so that the guide holes 73 formed in the guide flange 71 for guiding the lift of the rotation preventing guide rod 90 and the lift adjustment lift rod 70 are raised and lowered, respectively, thereby reducing the resistance received when the lift adjustment lift rod 70 is raised and lowered and achieving a smooth operation.

On the other hand, the present invention also includes a technique of an automatic origin maintaining apparatus 100 for automatically recognizing that the tilt adjusting lifter 70 is in an origin state when the sensor detector 102, which is lifted together with the tilt adjusting lifter 70, is lowered and detected by an origin detection sensor 105 provided on the circuit board 104, thereby maintaining the initial state of the mechanical module type actuator a.

As shown in fig. 9 and 10, as a technical configuration of the automatic origin maintaining apparatus 100, a pair of detector fixing rods 101 are integrally connected to an upper end of a guide flange 71 through a guide hole 83 formed to penetrate through an upper portion and a lower portion of a top block 80, a sensor detector 102 is attached to a lower portion of an upper end of the detector fixing rods 101, a circuit board fixing plate 103 is integrally attached to a bottom block 50 on a side where the detector fixing rods 101 are provided, a circuit board 104 is fixedly provided to the circuit board fixing plate 103 at a predetermined interval, and an origin detecting sensor 105 is provided at a lower portion of the circuit board 104.

Therefore, when the sensor detector 102, which ascends or descends together with the tilt adjusting lifter 70, descends, it is recognized that the tilt adjusting lifter 70 is in the original position state at the moment when the origin detection sensor 105 is detected by the detection protrusion 102a formed at the lower end, and thus, the driving of the motor 20 is automatically interrupted and the initial state of the mechanical module type actuator a is accurately maintained, and an error due to the operation can be prevented.

As shown in fig. 9 and 10, an upper limit stopper 108 and a lower limit stopper 109 are provided on the upper portion of the circuit board 104 and below the origin detection sensor 105, and when the detection protrusion 102a formed at the lower end of the sensor detector 102 comes into contact with one of the upper limit stopper 108 and the lower limit stopper 109, the upper limit elevation or the lower limit depression of the tilt adjustment lifter 70 is automatically limited, thereby preventing the mechanical module type actuator a from being damaged due to excessive elevation.

Next, a technical structure of a screen golf swing plate S to which the mechanical module type actuator a of the present invention is applied will be described.
