Technical Field

[0001] This utility model belongs to the field of mechanical technology, specifically a rotary lifting platform. Background Technology

[0002] In the field of Virtual Reality (VR), with the rapid development of technology, users' demands for immersive experiences are constantly increasing. To support users' free movement and precise operation in virtual environments, VR devices typically require specific interactive devices. Against this backdrop, highly flexible lifting and rotating platforms have gradually become an important auxiliary device for simulating realistic three-dimensional spatial motion and other scenarios.

[0003] Existing rotating lifting platforms typically use mechanical or hydraulic devices to enable users' vertical and rotational movements, aiming to provide a more realistic sense of immersion in VR systems. However, these platforms have limited lifting height, preventing users from experiencing significant height differences and allowing only minor height adjustments, thus limiting the overall user experience. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a rotating lifting platform that allows for greater adjustment of the platform height and provides a more realistic sense of immersion.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A rotating lifting platform, comprising:

[0007] A fixed frame, the fixed frame having a base and two uprights fixed on the base, each upright having a lifting frame slidably disposed thereon, the lifting frame sliding along the height direction;

[0008] Two vertical lifting chain drive mechanisms are respectively mounted on two uprights and connected to the lifting frame to drive the lifting frame to lift.

A limiting plate is fixed on the mounting plate, and the limiting plate is disposed within the active area between the two limiting blocks. The limiting plate has two limiting surfaces on both sides, and the two limiting surfaces can respectively abut against the corresponding two limiting blocks to restrict the rotating platform from swinging within a predetermined angle.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0028] like Figures 1 to 3 As shown, a rotating lifting platform includes: a fixed frame 2, two vertical lifting chain drive mechanisms 3, a rotating platform 4, a slewing bearing 5, and a rotating assembly 6. The fixed frame 2 has a base and two uprights 21 fixed on the base. A lifting frame 22 is slidably mounted on each upright 21 and slides along the height direction. The two vertical lifting chain drive mechanisms 3 are respectively mounted on the two uprights 21 and connected to the lifting frame 22 for driving the lifting frame 22 to rise and fall. The rotating platform 4 has connecting frames 41 on both sides, and mounting plates 42 are fixed on the connecting frames 41. The inner ring of the slewing bearing 5 is fixedly connected to the mounting plate 42, and the outer ring of the slewing bearing 5 is fixedly connected to the lifting frame 22. The rotating assembly 6 is mounted on the rotating platform 4 and connected to the outer ring of the slewing bearing 5 for driving the rotating platform 4 to rotate.

[0029] In this application, a vertical lifting chain drive mechanism 3 is installed on the two uprights 21 of the fixed frame 2. The drive mechanism is connected to the lifting frame 22 through the chain. When the drive mechanism is started, the chain moves and drives the lifting frame 22 to slide along the height direction of the uprights 21 to realize the lifting function. The slewing bearing 5 is connected between the lifting frame 22 and the rotating platform 4. Its inner ring is fixed to the connecting frame 41 through the mounting plate 42, and its outer ring is fixedly connected to the lifting frame 22. The slewing bearing 5 allows the rotating platform 4 to achieve smooth rotational movement relative to the lifting frame 22. A rotating component 6 is installed on the rotating platform 4. This component is connected to the outer ring of the slewing bearing 5. When the rotating component 6 is started, it drives the outer ring of the slewing bearing 5 to rotate, thereby driving the entire rotating platform 4 to perform horizontal rotational movement. Through the linkage of the vertical lifting chain drive mechanism 3 and the rotating component 6, the platform can realize a combination of vertical lifting and horizontal rotational movement to simulate complex movements in real three-dimensional space.

[0030] With the cooperation of the vertical lifting chain drive mechanism 3 and the rotating component 6, the platform can achieve precise adjustment of height and rotation angle to meet the needs of different application scenarios. Furthermore, the vertical lifting chain drive mechanism 3 can achieve greater adjustment within a wider height range.

[0031] In this application,

[0032] Specifically, the connecting frame 41 is a frame structure.

[0033] The frame structure is typically optimized with materials to reduce unnecessary material usage, lower the overall weight of the connecting frame 41, help reduce the load on the platform, and improve energy efficiency.

[0034] Specifically, the rotating assembly 6 includes a drive motor 61, a reducer 62, and a gear 63, one of which is an external gear slewing bearing 5; the drive motor 61 is connected to the gear 63 through the reducer 62, and the drive motor 61 and the reducer 62 are fixed on the connecting frame 41; the gear 63 meshes with the external teeth of the external gear slewing bearing 5, and the gear 63 can move around the outer ring of the external gear slewing bearing 5.

[0035] The drive motor 61 generates power, which is transmitted to the gear 63 through the reducer 62. The function of the reducer 62 is to reduce the speed and increase the torque to ensure the smoothness and accuracy of the platform's rotational movement. The first gear 63 meshes with the outer teeth of the external gear slewing bearing 5. The drive motor 61 drives the first gear 63 to rotate. The rotation of the gear 63 acts on the outer ring of the external gear slewing bearing 5, thereby driving the platform to achieve horizontal rotational movement. The inner ring of the external gear slewing bearing 5 is fixed on the mounting plate 42, and the outer ring is fixedly connected to the lifting frame 22. Through the movement of the first gear 63 around the outer ring of the external gear slewing bearing 5, the rotating platform 4 can achieve clockwise or counterclockwise rotation. The movement process is smooth and controllable.

[0036] Specifically, the drive motor 61 and the reducer 62 are located inside the connecting frame 41.

[0037] The drive motor 61 and reducer 62 are built into the connecting frame 41, making full use of the internal space of the connecting frame 41, reducing the overall size of the equipment, making the platform structure more compact, and the built-in design provides additional protection for the drive motor 61 and reducer 62, which can effectively avoid unexpected situations in the external environment and improve the durability of the equipment.

[0038] Specifically, two limiting blocks 221 are fixed on the lifting frame 22, forming an active area between the two limiting blocks 221. A limiting plate 421 is fixed on the mounting plate 42, and the limiting plate 421 is set in the active area between the two limiting blocks 221. The limiting plate 421 has two limiting surfaces 4211 on both sides, and the two limiting surfaces 4211 can abut against the corresponding two limiting blocks 221 respectively to restrict the rotating platform 4 from swinging within a predetermined angle.

[0039] The design of the limiting plate 421 effectively limits the swing amplitude of the rotating platform 4 by contacting the limiting surfaces 4211 on both sides with the limiting block 221, preventing the platform from exceeding the predetermined angle range and reducing safety hazards caused by excessive swing.

[0040] Specifically, a reinforcing plate 43 is fixed at the middle position of the bottom of the rotating platform 4.

[0041] The reinforcing plate 43 is located in the middle of the bottom of the rotating platform 4, which effectively enhances the overall rigidity of the platform and avoids deformation or bending due to long-term use or excessive load.
