Description

Technical Field

[0001] This utility model relates to the technical field of golf practice equipment, specifically a dynamic simulation platform for golf practice. Background Technology

[0002] For example, Chinese Patent Publication No. CN220345057U discloses an adjustable-angle golf practice platform, including a base, a fixed base, a tabletop at the top of the base, and the tabletop being rotatable relative to the base to adjust its tilt angle. A rotating platform is rotatably mounted at the top of the base, with the tabletop positioned on the side of the rotating platform away from the base. Two connecting ears are fixedly arranged opposite each other on the side of the rotating platform facing the tabletop, and the tabletop is rotatably connected to the corresponding connecting ears via a connecting plate. A linear module is fixedly mounted on the top surface of the rotating platform, with a support rod hinged to the output end of the linear module, and the other end of the support rod rotatably connected to the bottom end of the tabletop. This application's solution, through the hinged linear module and support rod, allows the movement of the linear module's output shaft to adjust the tabletop's tilt angle, facilitating the simulation of training fields with different tilt angles.

[0003] The aforementioned platform, with its rotating structure relative to the base, allows for adjustable tilt angles, but it lacks multi-point / multi-position height adjustment, resulting in limited adjustment and poor dynamic effect.

[0004] For example, Chinese Patent Publication No. CN2925553Y and Patent Application No. 200620062453.8 disclose a multi-functional golf practice table, including a practice platform, an adjustable support at the bottom of the platform, which can be adjusted and fixed at any angle, a rotating ball holder at the front of the platform, and holes at the four corners of the platform. By adjusting the angle of the platform and the height of the ball holder, various golf courses can be simulated.

[0005] The aforementioned platform, after being adjusted and fixed at any angle using adjustable supports, cannot be adjusted for multiple points or positions, resulting in limited adjustment and poor dynamic effect. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a dynamic simulation platform for golf practice with a reasonable structure. By setting multiple electric lifting and adjusting devices and controlling them to adjust the height difference, it simulates the natural practice field with different elevations outdoors.

[0007] The solution to the above technical problem is as follows:

[0008] A dynamic simulation platform for golf practice includes a base, a motion controller, a first electric lifting adjustment device, a second electric lifting adjustment device, a third electric lifting adjustment device, a fourth electric lifting adjustment device, and a top platform. The motion controller is electrically connected to the first, second, third, and fourth electric lifting adjustment devices. The four corners of the base are respectively fixedly connected to the bottoms of the first, second, third, and fourth electric lifting adjustment devices. The tops of the first, second, third, and fourth electric lifting adjustment devices are respectively fixedly connected to the opposite sides of the four corners of the top platform. The motion controller controls the height adjustment of the first, second, third, and fourth electric lifting adjustment devices by varying their elevation differences.

[0009] The beneficial effects of this dynamic simulation platform for golf practice are as follows: The dynamic controller of this product controls the lifting of the first, second, third, and fourth electric lifting adjustment devices, allowing for multi-point / multi-position height adjustment. The different heights of each electric lifting adjustment device create varying elevations at the four corners of the top platform, resulting in a dynamic effect similar to a natural outdoor practice area with varying elevations. This enhances the simulation of dynamic motion. The dynamic controller can control the elevation difference of each electric lifting adjustment device to adjust the dynamic effect. The varying elevations of the four electric lifting adjustment devices allow for a certain degree of tilt freedom on the top platform, simulating the terrain of an actual outdoor golf course, thus increasing practice interest and allowing for practice at various difficulty levels.

Detailed Implementation

[0028] like Figures 1-36 The image shows a motion simulation platform for golf practice, comprising a base 1, a motion controller 2, a first electric lifting adjustment device 3, a second electric lifting adjustment device 4, a third electric lifting adjustment device 5, a fourth electric lifting adjustment device 6, and a top platform 7. The first electric lifting adjustment device 3, the second electric lifting adjustment device 4, the third electric lifting adjustment device 5, and the fourth electric lifting adjustment device 6 have identical structures. The motion controller 2 is electrically connected to the first electric lifting adjustment device 3, the second electric lifting adjustment device 4, the third electric lifting adjustment device 5, and the fourth electric lifting adjustment device 6 via wires. The motion controller 2 can also be referred to as a motion control system. The top surface of the top platform 7 is flat. The top platform 7 includes a top metal support frame and several top flat metal plates. The top of the top metal support frame is welded to a portion of the top flat metal plates, and the top of the top metal support frame is bolted to the remaining portion of the top flat metal plates. The fixing method is selected according to the actual situation. The metal of the top metal support frame and the several top flat metal plates is made of iron or steel. The base 1 includes a bottom metal support frame and several bottom flat metal plates. The bottom of the bottom metal support frame is welded to a portion of the bottom flat metal plates, and the bottom of the bottom metal support frame is bolted to the remaining portion of the bottom flat metal plates. The fixing method is selected according to the actual situation. The metal of the bottom metal support frame and the several bottom flat metal plates is made of iron or steel.

[0029] The four corners of the base 1 are respectively fixedly connected to the bottoms of the first electric lifting adjustment device 3, the second electric lifting adjustment device 4, the third electric lifting adjustment device 5, and the fourth electric lifting adjustment device 6 using screw assemblies or welding. The tops of the first electric lifting adjustment device 3, the second electric lifting adjustment device 4, the third electric lifting adjustment device 5, and the fourth electric lifting adjustment device 6 are respectively fixedly connected to the four corners of the top platform 7 using screw assemblies, snap-fit, through-connection, insertion, or snap-fit ​​connection structures. The four electric lifting adjustment devices support the top platform 7. During operation, the motion controller 2 controls the height difference between the first electric lifting adjustment device 3, the second electric lifting adjustment device 4, the third electric lifting adjustment device 5, and the fourth electric lifting adjustment device 6, thereby creating a dynamic top platform 7. The motion controller 2 controls the height difference between the first electric lifting adjustment device 3, the second electric lifting adjustment device 4, the third electric lifting adjustment device 5, and the fourth electric lifting adjustment device 6. The four electric lifting adjustment devices (3, 4, 5, and 6) operate at varying heights, creating different elevation differences at the four corners of the top platform 7. The lifting range of each device is 0-5 cm. The motion controller 2 can control the elevation difference of each device to adjust the dynamic effect. The varying elevation differences of the four devices allow for a degree of tilt freedom on the top platform, simulating the terrain of an actual golf course. The platform can be adjusted to any side to create a slope, increasing the difficulty and enhancing the learning experience. Of course, when all four devices are at the same height, the platform simulates a flat terrain.

[0030] The top surface of the top platform 7 is covered with a golf practice mat 71, which has a ball-loading hole 711. The golf practice mat 71 is an artificial turf mat. One end of the top platform 7 has a ball machine mounting hole 72. An electric ball machine 73 is embedded in the ball machine mounting hole 72 and fixedly connected with screws. The electric ball machine 73 is an existing technology product and can be used immediately after installation. The electric ball machine 73 fits perfectly into the ball machine mounting hole 72. The top surface of the electric ball machine 73 is flush with the top surface of the top platform 7. The ball-ejection hole at the top of the electric ball machine 73 is vertically aligned with the ball-loading hole 711. The electric ball machine 73 will automatically push the ball from the ball-ejection hole to the opening of the ball-loading hole 711 at the top, ready to be hit.

[0031] Further, in the preferred technical solution: the first electric lifting adjustment device 3 includes a first drive motor 31, a first gear reducer 32, a first rotating screw 33, a first spiral lifting seat 34, and a first elastic tension reset device 35. The first rotating screw 33 and the first spiral lifting seat 34 are vertically arranged. The first spiral lifting seat 34 has a first internal threaded hole 341 vertically opened in the middle of its body. The first rotating screw 33 is movably screwed into the first internal threaded hole 341 and forms a threaded connection with the first spiral lifting seat 34. The top of the first spiral lifting seat 34 is movably connected to the first elastic tension reset device 35. The top of the first elastic tension reset device 35 is fixedly connected to the opposite side of the top platform 7 by a screw assembly, snap-fit, through-connection, insertion, or snap-fit ​​connection structure.

[0032] The specific structures of the first drive motor 31 and the first gear reducer 32 are existing technology products, which can be used simply by assembling them together. The first gear reducer 32 is fixedly connected to the first corner of the base 1 with a screw assembly. The first drive motor 31 is driven by the first gear reducer 32, and the first rotating screw 33 is also driven by the first gear reducer 32. The first drive motor 31 drives the internal gear assembly of the first gear reducer 32 to rotate forward and backward, and the internal gear assembly of the first gear reducer 32 drives the first rotating screw 33 to rotate forward and backward. The first rotating screw 33 drives the first spiral lifting seat 34 to rise and fall, and the first elastic tension reset device 35 and the top platform 7 rise and fall synchronously. The first drive motor 31 is connected to the motion controller 2 via a wire. When the motion controller 2 controls the first drive motor 31 to rotate forward, the first drive motor 31 drives the first gear reducer 32 to rotate forward synchronously, the internal gear assembly of the first gear reducer 32 drives the first rotating screw 33 to rotate forward synchronously, and the first elastic tension reset device 35 and the top platform 7 rise synchronously. When controller 2 controls the first drive motor 31 to rotate in the reverse direction, the first drive motor 31 drives the first gear reducer 32 to rotate synchronously in the reverse direction. The internal gear assembly of the first gear reducer 32 drives the first rotating screw 33 to rotate synchronously in the reverse direction. The first elastic tension reset device 35 and the top platform 7 descend synchronously. Due to the height difference of the four electric lifting adjustment devices, the top platform 7 is tilted due to the height difference. The first spiral lifting seat 34 and the first elastic tension reset device 35 are separated due to the imbalance of the top platform 7. The first elastic tension reset device 35 plays an elastic pulling and buffering role. Therefore, the first spiral lifting seat 34 and the first elastic tension reset device 35 cannot be in rigid contact. The first spiral lifting seat 34 and the first elastic tension reset device 35 can only be connected by a movable elastic connection. During operation, due to the height difference of the four electric lifting adjustment devices, when the top platform 7 on the first corner position is tilted due to the height difference, the top platform 7 on the first corner position will be elastically stretched and buffered by the first elastic tension reset device 35.

[0033] The second electric lifting adjustment device 4 includes a second drive motor 41, a second gear reducer 42, a second rotating screw 43, a second spiral lifting seat 44, and a second elastic tension reset device 45. The second rotating screw 43 and the second spiral lifting seat 44 are vertically arranged. The second spiral lifting seat 44 has a second internal threaded hole 441 vertically opened in the middle of its body. The second rotating screw 43 is movably screwed into the second internal threaded hole 441 and forms a threaded connection with the second spiral lifting seat 44. The top of the second spiral lifting seat 44 is movably connected to the second elastic tension reset device 45. The top of the second elastic tension reset device 45 is fixedly connected to the opposite side of the top platform 7 by a screw assembly, snap-fit, through-connection, insertion, or snap-fit ​​connection structure.

[0034] The second gear reducer 42 is fixedly connected to the second corner of the base 1 with screws. The second drive motor 41 is driven by the second gear reducer 42, and the second rotating screw 43 is also driven by the second gear reducer 42. The second drive motor 41 drives the internal gear assembly of the second gear reducer 42 to rotate in both directions, which in turn drives the second rotating screw 43 to rotate in both directions. The second rotating screw 43 drives the second spiral lifting seat 44 to rise and fall, and the second elastic tension reset device 45 and the top platform 7 rise and fall synchronously. The second drive motor 41 is connected to the motion controller 2 via wires. The specific structures of the second drive motor 41 and the second gear reducer 42 are existing technologies and can be used after assembly. When the motion controller 2 controls the second drive motor 41 to rotate in the forward direction, the second drive motor 41 drives the second gear reducer 42 to rotate synchronously in the forward direction, the internal gear assembly of the second gear reducer 42 drives the second rotating screw 43 to rotate synchronously in the forward direction, and the second elastic tension reset device 45 and the top platform 7 rise synchronously. When controller 2 controls the second drive motor 41 to rotate in the reverse direction, the second drive motor 41 drives the second gear reducer 42 to rotate synchronously in the reverse direction. The internal gear assembly of the second gear reducer 42 drives the second rotating screw 43 to rotate synchronously in the reverse direction. The second elastic tension reset device 45 and the top platform 7 descend synchronously. Due to the height difference of the four electric lifting adjustment devices, the top platform 7 is tilted due to the height difference. The second spiral lifting seat 44 and the second elastic tension reset device 45 are separated due to the imbalance of the top platform 7. The second elastic tension reset device 45 plays an elastic tension buffering role. Therefore, the second spiral lifting seat 44 and the second elastic tension reset device 45 cannot be in rigid contact. The second spiral lifting seat 44 and the second elastic tension reset device 45 can only be connected by a movable elastic connection. During operation, due to the height difference of the four electric lifting adjustment devices, when the top platform 7 on the second corner position is tilted due to the height difference, the top platform 7 on the second corner position will be elastically stretched and buffered by the second elastic tension reset device 45.

[0035] The third electric lifting adjustment device 5 includes a third drive motor 51, a third gear reducer 52, a third rotating screw 53, a third spiral lifting seat 54, and a third elastic tension reset device 55. The third rotating screw 53 and the third spiral lifting seat 54 are vertically arranged. The third spiral lifting seat 54 has a third internal threaded hole 541 vertically opened in the middle of its body. The third rotating screw 53 is movably screwed into the third internal threaded hole 541 and forms a threaded connection with the third spiral lifting seat 54. The top of the third spiral lifting seat 54 is movably connected to the third elastic tension reset device 55, and the top of the third elastic tension reset device 55 is fixedly connected to the opposite side of the top platform 7.

[0036] The third gear reducer 52 is fixedly connected to the third corner of the base 1 with a screw assembly. The third drive motor 51 is driven by the third gear reducer 52, and the third rotating screw 53 is also driven by the third gear reducer 52. The third drive motor 51 drives the internal gear assembly of the third gear reducer 52 to rotate in both directions, which in turn drives the third rotating screw 53 to rotate in both directions. The third rotating screw 53 drives the third spiral lifting seat 54 to rise and fall, and the third elastic tension reset device 55 and the top platform 7 rise and fall synchronously. The third drive motor 51 is connected to the motion controller 2 via a wire. The specific structure of the third drive motor 51 and the third gear reducer 52 is existing technology. When the motion controller 2 controls the third drive motor 51 to rotate in the forward direction, the third drive motor 51 drives the third gear reducer 52 to rotate synchronously in the forward direction, the internal gear assembly of the third gear reducer 52 drives the third rotating screw 53 to rotate synchronously in the forward direction, and the third elastic tension reset device 55 and the top platform 7 rise synchronously. When the third drive motor 51 rotates in the reverse direction, it drives the third gear reducer 52 to rotate synchronously in the reverse direction. The internal gear assembly of the third gear reducer 52 drives the third rotating screw 53 to rotate synchronously in the reverse direction, and the third elastic tension reset device 55 and the top platform 7 descend synchronously. Due to the height difference of the four electric lifting adjustment devices, the top platform 7 is tilted due to the height difference. The third spiral lifting seat 54 and the third elastic tension reset device 55 are separated due to the imbalance of the top platform 7. The third elastic tension reset device 55 plays an elastic tension buffering role. Therefore, the third spiral lifting seat 54 and the third elastic tension reset device 55 cannot be in rigid contact. The third spiral lifting seat 54 and the third elastic tension reset device 55 can only be connected by a movable elastic connection. During operation, due to the height difference of the four electric lifting adjustment devices, when the top platform 7 on the third corner position is tilted due to the height difference, the top platform 7 on the third corner position will be elastically stretched and buffered by the third elastic tension reset device 55.

[0037] The fourth electric lifting adjustment device 6 includes a fourth drive motor 61, a fourth gear reducer 62, a fourth rotating screw 63, a fourth spiral lifting seat 64, and a fourth elastic tension reset device 65. The fourth rotating screw 63 and the fourth spiral lifting seat 64 are vertically arranged. The fourth spiral lifting seat 64 has a fourth internal threaded hole 641 vertically opened in the middle of its body. The fourth rotating screw 63 is movably screwed into the fourth internal threaded hole 641 and forms a threaded connection with the fourth spiral lifting seat 64. The top of the fourth spiral lifting seat 64 is movably connected to the fourth elastic tension reset device 65, and the top of the fourth elastic tension reset device 65 is fixedly connected to the opposite side of the top platform 7.

[0038] The fourth gear reducer 62 is fixedly connected to the fourth corner of the base 1 with screws. The fourth drive motor 61 is driven by the fourth gear reducer 62, and the fourth rotating screw 63 is also driven by the fourth gear reducer 62. The fourth drive motor 61 drives the internal gear assembly of the fourth gear reducer 62 to rotate in both directions, which in turn drives the fourth rotating screw 63 to rotate in both directions. The fourth rotating screw 63 drives the fourth spiral lifting seat 64 to rise and fall, and the fourth elastic tension reset device 65 and the top platform 7 rise and fall synchronously. The fourth drive motor 61 is connected to the motion controller 2 via wires. The specific structures of the fourth drive motor 61 and the fourth gear reducer 62 are existing technologies and can be used after assembly. When the motion controller 2 controls the fourth drive motor 61 to rotate in the forward direction, the fourth drive motor 61 drives the fourth gear reducer 62 to rotate synchronously in the forward direction, the internal gear assembly of the fourth gear reducer 62 drives the fourth rotating screw 63 to rotate synchronously in the forward direction, and the fourth elastic tension reset device 65 and the top platform 7 rise synchronously. When controller 2 controls the fourth drive motor 61 to rotate in the reverse direction, the fourth drive motor 61 drives the fourth gear reducer 62 to rotate in the reverse direction synchronously. The internal gear assembly of the fourth gear reducer 62 drives the fourth rotating screw 63 to rotate in the reverse direction synchronously. The fourth elastic tension reset device 65 and the top platform 7 descend synchronously. Due to the height difference of the four electric lifting adjustment devices, the top platform 7 is tilted due to the height difference. The fourth spiral lifting seat 64 and the fourth elastic tension reset device 65 are separated due to the imbalance of the top platform 7. The fourth elastic tension reset device 65 plays an elastic tension buffering role. Therefore, the fourth spiral lifting seat 64 and the fourth elastic tension reset device 65 cannot be in rigid contact. The fourth spiral lifting seat 64 and the fourth elastic tension reset device 65 can only be connected by a movable elastic connection. During operation, due to the height difference of the four electric lifting adjustment devices, when the top platform 7 on the fourth corner position is tilted due to the height difference, the top platform 7 on the fourth corner position will be elastically stretched and buffered by the fourth elastic tension reset device 65.

[0039] When the top platform 7 is tilted and tends to be flat / horizontal, the top platform 7 will automatically be elastically pulled back to the center by the first elastic tension reset device 35, the second elastic tension reset device 45, the third elastic tension reset device 55, and the fourth elastic tension reset device 65, so that the top platform 7 is reset to a flat / horizontal state.

[0040] The above describes a further refined structure for the first electric lifting adjustment device 3, the second electric lifting adjustment device 4, the third electric lifting adjustment device 5, and the fourth electric lifting adjustment device 6. This design prevents rigid connections between the elastic tension and reset devices and the screw lifting seats. The dynamic tension and reset structures of the elastic tension and reset devices and the screw lifting seats are rationally designed, resulting in overall dynamic stability, preventing jamming, extending service life, and reducing mechanical wear. Each elastic tension and reset device exhibits good tension performance and reset effect. The overall dynamic balance between the elastic tension and reset devices and the top platform 7 is well coordinated. The first drive motor 31, the second drive motor 41, the third drive motor 51, and the fourth drive motor 61 are all AC asynchronous motors with forward and reverse rotation functions. The AC asynchronous motors use 100V-120V, 50 / 60Hz or 220V-240V, 50 / 60Hz.

[0041] Further, in the preferred technical solution: the housing of the first drive motor 31 is fixedly connected to the housing of the first gear reducer 32 using a screw assembly. The motor shaft of the first drive motor 31 is inserted into the first gear reducer 32 and meshes with the first gear of the first gear reducer 32. The first gear is a small gear. The end of the motor shaft has toothed segments, so the motor shaft meshes with the first gear of the first gear reducer 32 through the toothed segments of the motor shaft. The bottom section of the first rotating screw 33 is inserted into the first gear reducer 32, and the bottom section of the first rotating screw 33 passes through the center of the last gear of the first gear reducer 32. The last gear of the first gear reducer 32 is a large gear. The bottom section of the first rotating screw 33 is clamped or welded to the last gear of the first gear reducer 32 for fixed connection. During operation, the motor shaft of the first drive motor 31 drives the first gear of the first gear reducer 32 to rotate, and the first gear synchronously drives the first gear. The next-stage gear assembly rotates until the driving force is transmitted to the last gear of the first gear reducer 32. The last gear of the first gear reducer 32 synchronously drives the first rotating screw 33 to rotate. The motor shaft of the first drive motor 31 rotates in the forward direction, and the corresponding gear assembly inside the first gear reducer 32 and the first rotating screw 33 rotate in the forward direction. The first spiral lifting seat 34 rises, and the first elastic tension reset device 35 and the top platform 7 rise synchronously. The motor shaft of the first drive motor 31 rotates in the reverse direction, and the corresponding gear assembly inside the first gear reducer 32 and the first rotating screw 33 rotate in the reverse direction.

The shape of the platform mounting recess is consistent with the shape of the dynamic simulation platform of this golf practice, and the depth of the platform mounting recess is basically consistent with the height of the dynamic simulation platform of this golf practice. The soft rubber corrugated frame 17 is used to cover or shield the gaps at the edge to prevent impurities from falling into the platform mounting recess. At the same time, when the top platform 7 is in motion, the soft rubber corrugated frame 17 plays an elastic buffer role of elastic compression and elastic extension and reset, always keeping the edge gaps covered or shielded.

[0075] The dynamic simulation platform for golf practice is square in shape, which facilitates manufacturing and installation.
