[0028] 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.

[0029] like Figs. 1 to 3 As shown, a tilting device for a suspended platform 4 includes: a fixed base 2, a movable base 3, a platform 4, and a drive assembly 5. The movable base 3 is hinged relative to the fixed base 2; the platform 4 is fixed on the fixed base 2; the drive assembly 5 is connected to the movable base 3 to drive the movable base 3 to swing. The drive assembly 5 includes a drive shaft 51, a drive block 52, and two connector assemblies 53. The drive shaft 51 is rotatably mounted on the fixed base 2. One end of the drive block 52 is fixed to the drive shaft 51. The two connector assemblies 53 are rotatably connected to the other end of the drive block 52, and the other ends of the two connector assemblies 53 are rotatably connected to the movable base 3.

[0030] In this application, the drive shaft 51 rotates, and the drive block 52 rotates with the drive shaft 51 to generate power transmission. The other end of the drive block 52 is connected to the movable seat 3 through two connector assemblies 53. The rotational motion of the drive block 52 is converted into the swinging motion of the movable seat 3 through the connector assembly 53, so that the movable seat 3 tilts relative to the fixed seat 2.

[0031] Compared to traditional multi-degree-of-freedom hydraulic control systems, this device adopts a design of drive shaft 51 and joint assembly 53, which reduces the complex hydraulic transmission mechanism and multiple support structures. The device has fewer components and a more streamlined structural design, which significantly reduces manufacturing costs.

[0032] Specifically, the movable seat 3 is connected to the fixed seat 2 via a hinge assembly 6. The hinge assembly 6 includes a rotating shaft 61, and two first bearing seats 62 are respectively provided at both ends of the rotating shaft 61. The first bearing seats 62 are fixed on the fixed seat 2. The movable seat 3 is fixedly connected to the rotating shaft 61 via a connecting block 31.

[0033] The rotating shaft 61 is fixed to the fixed base 2 by two first bearing seats 62, which provides reliable support and ensures the overall structure is stable during the movement of the movable base 3, making it less prone to shaking or deviation. The rotating shaft 61 achieves smooth rotation through the first bearing seats 62, reducing friction. The two first bearing seats 62 are evenly distributed at both ends of the rotating shaft 61, sharing the force on the rotating shaft 61, reducing the risk of excessive force at a single point, and improving the durability of the device.

[0034] Specifically, there are two connecting blocks 31, which are spaced apart.

[0035] Two connecting blocks 31 are arranged at intervals, which can disperse the stress on the rotating shaft 61 to two places, effectively reduce the stress burden of a single connection point, and avoid shaking or deformation of the movable seat 3 during movement due to uneven stress.

[0036] Specifically, the driving assembly 5 further comprises a driving motor 54, an output shaft of the driving motor 54 is fixedly connected with the driving shaft 51 through a speed reducer 55, and the driving motor 54 is fixed on the fixed seat 2.

[0037] The output shaft of the driving motor 54 is fixedly connected with the driving shaft 51 through the speed reducer 55, the speed reducer 55 converts the high-speed and low-torque output of the driving motor 54 into low-speed and high-torque output, the driving shaft 51 is driven to rotate by the high-torque output of the speed reducer 55, and the driving block 52 fixedly connected with the driving shaft 51 also rotates, and the rotation of the driving block 52 transmits power to the movable seat 3 through the joint assembly 53.

[0038] Specifically, the other end of the driving shaft 51 is connected to the fixed seat 2 through two second bearing seats.

[0039] The two second bearing seats are distributed at the other end of the driving shaft 51, forming a double-point support structure to enhance the stability of the driving shaft 51.

[0040] Specifically, the fixed seat 2 has a first mounting portion 21 and a second mounting portion 22, a difference is formed between the first mounting portion 21 and the second mounting portion 22, the second mounting portion 22 is closer to the movable seat 3, the first bearing seat 62 is mounted on the first mounting portion 21, and the second bearing seat is mounted on the second mounting portion 22.

[0041] Specifically, the joint assembly 53 comprises two fisheye joints 531 fixedly connected together.

[0042] The fisheye joint 531 can flexibly rotate in multiple directions, allowing the movable seat 3 to have greater freedom during inclined movement, adapting to complex angle changes, and allowing slight deviations during movement, improving the service life of the equipment, the flexibility of the fisheye joint 531 can absorb and buffer the impact force generated during movement, reduce the vibration and noise during operation of the device, and improve the operation stability.

[0043] It should be noted that all directional indications in the embodiments of the present application, such as up, down, left, right, front, back, etc., are only used to explain the relative positional relationship between components, the movement condition, etc., between components in a certain specific posture, as shown in the drawings, if the specific posture changes, the directional indications also change accordingly.
