[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application clearer and more understandable, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0027] Based on this, it is possible to improve the technical problem that the angle control device in the related art is prone to shaking during use, which affects the detection effect of the pod. The embodiments of the present application provide the following solutions.

[0028] Please refer to Figures 1 to 5 simultaneously, the embodiments of the present application provide an angle control device, including an angle control mechanism 10, a connection assembly 20 and a plurality of shock pads 30;

[0029] The connection assembly 20 includes a top plate 21, a fixed seat 22 and a plurality of bolts 23. The top plate 21 is disposed on the top of the angle control mechanism 10, and the top plate 21 is connected to the fixed seat 22 by bolts 23;

[0030] The shock pad 30 includes a base 31 and a pressurized bladder 32. The base 31 is configured to be between the top plate 21 and the fixed seat 22. An installation cavity 311 is provided on the base 31. The installation cavity 311 can be compressed due to the vibration of the top plate 21 relative to the fixed seat 22 and the volume becomes smaller. The pressurized bladder 32 is installed and filled in the installation cavity 311, and a medium with a set pressure is filled in the pressurized bladder 32, so that the pressurized bladder 32 can form an inhibition of the reduction of the volume of the installation cavity 311.

[0031] As can be seen from the above, by providing a mounting cavity 311 on the base 31 and mounting a pressurized bladder 32 filled with a pressure medium in the mounting cavity 311, when the shock pad 30 disposed between the top plate 21 and the fixed seat 22 is compressed due to the vibration of the equipment, the elastic buffer vibration isolation effect of the shock pad 30 can be achieved by relying on the elastic reaction force of the pressurized bladder 32 under pressure. Moreover, by changing the medium pressure in the pressurized bladder 32, the elastic deformation performance of the pressurized bladder 32 can be changed, which is beneficial to increasing the applicable range of the vibration isolation performance of the shock pad 30. The base 31 is preferably integrally injection-molded from a rubber material, and the rubber material can be any one of NBR (nitrile rubber), EPDM (ethylene propylene diene monomer rubber), etc. In this way, the connecting portion can expand and contract correspondingly in response to the shape change of the mounting cavity 311, and the base 31 itself can also have the vibration isolation effect of elastic deformation. From the perspective of reducing the probability of the angle control device shaking during use, and with a stable mechanical structure and high system reliability, the detection effect of the pod is improved.

[0032] Optionally, in some embodiments, please refer to Figures 3 to 5 , a limiting platform 321 protruding outward is formed by the middle parts on both sides of the pressurized bladder 32, and a limiting groove 312 for cooperating with the limiting platform 321 is provided in the mounting cavity 311.

[0033] With such a setting, as the pressurized bladder 32 is inserted into the mounting cavity 311, the limiting platform 321 is clamped in the limiting groove 312, thereby constituting the limitation of the pressurized bladder 32 in the mounting cavity 311. This design has a simple structure, is convenient for processing and manufacturing, and due to the deformable characteristics of the pressurized bladder 32, the pressurized bladder 32 can be slightly flattened during insertion to allow the limiting platform 321 to enter the limiting groove 312 of the mounting cavity 311.

[0034] Optionally, in some embodiments, please refer to Figure 4 , a filling port 322 for the medium to be filled is provided at the edge of the pressurized bladder 32.

[0035] With such a setting, in order to facilitate the filling of the medium into the inner cavity of the pressurized bladder 32, a filling port 322 for the medium to be filled is provided at the edge portion of the pressurized bladder 32.

[0036] Optionally, in some embodiments, please refer to Figures 3 to 5 , an insertion hole 313 is provided on the base 31, and the bolt 23 is inserted into the insertion hole 313.

[0037] With such a setting, the bolt 23 is inserted into the insertion hole 313 from the bottom of the base 31 to form the assembly between the top plate 21 and the fixed seat 22. The insertion hole 313 penetrates through the entire base 31, and the top of the bolt 23 passes through the insertion hole 313 and is connected to the fixed seat 22 to improve the connection reliability between the fixed seat 22 and the shock pad 30.

[0038] Optionally, in some embodiments, refer to Figures 3 to 5 , a plugging pair hole 323 is formed in the middle of the pressurizing bladder 32, and the inner wall of the plugging pair hole 323 is in a corrugated shape.

[0039] With such a setting, the plugging pair hole 323 is aligned with the plugging hole 313 so that the bolt 23 can be inserted into both of them. In this way, the bolt 23 is inserted through and arranged in the plugging pair hole 323 and the plugging hole 313 and is located at the axis of the entire shock pad 30, which can make the load-bearing center of gravity of the shock pad 30 located at the central part of the pressurizing bladder 32, so that the force distribution of the pressurizing bladder 32 being squeezed is balanced, which is beneficial to the exertion of the elastic vibration isolation effect of the pressurizing bladder 32. In order to make the bladder skin of the part of the pressurizing bladder 32 located on the inner wall of the plugging pair hole 323 have smoother elastic deformation in the axial direction of the plugging pair hole 323, that is, in the load-bearing direction of the shock pad 30, and reduce the occurrence of irregular wrinkles and ruptures of the bladder skin of the inner wall part, the bladder skin of the pressurizing bladder 32 located on the inner wall of the plugging pair hole 323 is also configured to be corrugated in the axial direction.

[0040] Optionally, in some embodiments, refer to Figures 2 to 3 , a plurality of first threaded holes 24 for fitting the bolt 23 are formed in both the top plate 21 and the fixing seat 22.

[0041] With such a setting, the bolt 23 is rotatably connected in the first threaded holes 24 on the top plate 21 and the fixing seat 22, so that the top plate 21 and the fixing seat can be firmly connected through the bolt 23.

[0042] Optionally, in some embodiments, refer to Figures 1 to 3 , the connecting component 20 further includes a nut 25, and the nut 25 is rotatably connected to the bolt 23 and abuts against the side wall of the fixing seat 22 on the side away from the top plate 21.

[0043] With such a setting, the nut 25 is used in cooperation with the bolt 23 to ensure that the fixing seat 22 and the top plate 21 are firmly fixed together.
