Adjustable mechanism for a motion platform

Abstract

This utility model relates to the field of motion platform technology, specifically an adjustable mechanism for a motion platform, including a support frame. A threaded sleeve is fixedly connected to the bottom of the support frame, and a lifting screw is threadedly connected to the threaded sleeve. A rotating block is fixedly connected to the bottom of the lifting screw, and a foot pad is rotatably connected to the bottom of the rotating block. By rotating the rotating block, the lifting screw is rotated, which in turn moves the foot pad up and down, thereby adjusting the height of the support frame and thus the height of the motion platform. This allows for adjustment to suit the usage needs of different scenarios and users. Multiple sets of foot pads can be adjusted to different heights to adapt to uneven ground, ensuring that the motion platform does not tilt.

Description

Technical Field

[0001] This utility model relates to the field of motion platform technology, specifically to an adjustable mechanism for a motion platform. Background Technology

[0002] A motion platform is a platform capable of movement. Through advanced motors, drives, and control systems, it achieves precise motion control of the platform in multiple degrees of freedom, ensuring smoothness, accuracy, and rapid response. It uses various sensors to perceive the platform's motion status and the user's body movements in real time, providing feedback signals for motion control and enabling interactive control. It has wide applications in entertainment, training, and other fields.

[0003] When installing a motion platform, it is typically mounted on a support frame, which is then welded and fixed to the ground. However, this method prevents the platform's height from being adjusted, making it unsuitable for different scenarios and user needs. Furthermore, when the ground is uneven, the platform may tilt slightly. To address this issue, we propose an adjustable height mechanism to accommodate different scenarios and user needs, while also preventing tilting. Utility Model Content

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1: Please refer to Figure 1-2 This utility model provides a technical solution: an adjustable mechanism for a dynamic platform, including a support frame 1, a threaded sleeve 2 fixedly connected to the bottom of the support frame 1, a lifting screw 3 threadedly connected to the threaded sleeve 2, a rotating block 4 fixedly connected to the bottom of the lifting screw 3, and a foot pad 5 rotatably connected to the bottom of the rotating block 4.

[0028] In use, manually rotate the rotating block 4 to drive the lifting screw 3 to rotate. Under the action of the threaded sleeve 2, the lifting screw 3 moves up and down, which drives the foot pads 5 to move up and down, thereby adjusting the height of the support frame 1. In turn, the height of the dynamic platform can be adjusted to adapt to the usage needs of different scenarios and different people. Multiple sets of foot pads 5 can be adjusted to different heights to adapt to uneven ground and ensure that the dynamic platform will not tilt.

[0029] The bottom of the foot pad 5 is fixedly connected to an anti-slip pad 6, which can increase the friction with the ground and prevent the foot pad 5 from shifting.

[0030] The foot pad 5 has several sets of first mounting holes, and the anti-slip pad 6 has several sets of second mounting holes. The first mounting holes and the second mounting holes are connected.

[0031] Example 2: Please refer to Figure 3-4 The difference from Embodiment 1 of this application is that a sliding cover 8 is fixedly connected to the bottom of the support frame 1, and an installation cover 7 is slidably fitted on the outside of the sliding cover 8. The bottom of the installation cover 7 is fixedly connected to the top of the threaded sleeve 2. A damping shock absorber 9 and a spring 10 are fixedly connected to the bottom of the inner cavity of the installation cover 7. The tops of the damping shock absorber 9 and the spring 10 are both fixedly connected to the top of the inner cavity of the sliding cover 8, and the spring 10 is fitted on the outside of the damping shock absorber 9.

[0032] When the motion platform is running, the damping shock absorber 9 and the spring 10 can reduce the vibration of the motion platform to a certain extent, thereby improving the user experience.

[0033] Example 3: Please refer to Figure 5-6 The difference from Embodiments 1 and 2 of this application is that the support frame 1 is provided with a mounting block 17 at the bottom, and a slider 14 is fixedly connected to the top of the mounting block 17. The bottom of the support frame 1 is provided with a sliding groove 13 that matches the slider 14. The slider 14 is slidably connected to the sliding groove 13. The bottom of the mounting block 17 is fixedly connected with a mounting plate 12. Two sets of sliding plates 11 are slidably connected to the top of the mounting plate 12. The bottom of the mounting plate 12 is fixedly connected to the top of the threaded sleeve 2. A bidirectional screw 18 is rotatably passed through the mounting block 17. The bidirectional screw 18 is threaded through the sliding plate 11.

[0034] Manually rotating the bidirectional screw 18 can move the two sets of sliding plates 11 away from the support frame 1. At this time, the mounting block 17 can slide at the bottom of the support frame 1, thereby adjusting the foot pad 5 to a suitable position to adapt to different installation situations. After adjustment, rotate the bidirectional screw 18 again to make the two sets of sliding plates 11 clamp the support frame 1 and position the foot pad 5.

[0035] A pressure plate 15 is fixedly connected to the side of the sliding plate 11 near the support frame 1. Several sets of protrusions are provided on the side of the pressure plate 15 near the support frame 1 to increase friction and ensure positioning effect.

[0036] Two sets of limiting rings 16 are fixedly sleeved on the outside of the bidirectional screw 18. The side of the limiting ring 16 closest to the mounting block 17 is slidably connected to the mounting block 17 to prevent the bidirectional screw 18 from sliding on the mounting block 17 and affecting the operation of the mechanism.

[0037] Several sets of reinforcing connecting blocks 19 are provided on the sliding plate 11 to enhance the overall strength of the sliding plate 11 and extend its service life.

[0038] Working principle: When in use, manually rotate the rotating block 4 to drive the lifting screw 3 to rotate. Under the action of the threaded sleeve 2, the lifting screw 3 moves up and down, driving the foot pads 5 to move up and down, thereby adjusting the height of the support frame 1, and thus the height of the dynamic platform can be adjusted to adapt to the usage needs of different scenarios and different people. Multiple sets of foot pads 5 can be adjusted to different heights to adapt to uneven ground, ensuring that the dynamic platform will not tilt. The anti-slip pad 6 can increase the friction with the ground and prevent the foot pads 5 from shifting.

[0039] When the motion platform is running, the damping shock absorber 9 and the spring 10 can reduce the vibration of the motion platform to a certain extent, thereby improving the user experience.

[0040] Manually rotating the bidirectional screw 18 can move the two sets of sliding plates 11 away from the support frame 1. At this time, the mounting block 17 can slide at the bottom of the support frame 1, thereby adjusting the foot pad 5 to a suitable position to adapt to different installation situations. After adjustment, rotate the bidirectional screw 18 again to make the two sets of sliding plates 11 clamp the support frame 1 and position the foot pad 5.
