The lower half part of the outer wall of the sleeve 451 and the inner side wall of the partition 453 are fixedly provided with a plurality of choke rings 456, and the choke rings 456 distributed inside and outside are staggered with each other in the vertical direction.
So that the hydraulic oil between the partition cylinder 453 and the bottom wall of the protective case 410 passes through the oil groove 455 to flow upward, and then enters the outer annular groove, and then enters the inner annular groove from the upper side under the barrier of the cap assembly 460. And turbulent flow is formed by the blocking effect of the plurality of choke rings 456 on hydraulic oil, so that the resistance of the hydraulic oil to flow is increased. Similarly, when the piston rod 440 moves downward to drive the piston plate assembly 480 to move downward and squeeze the hydraulic oil in the lower half of the sleeve 451, the hydraulic oil passes through the arc-shaped through grooves between the bosses 452 and enters the annular groove on the inner side, and the hydraulic oil is blocked by the choke ring 456 to form turbulence, so that the flow resistance of the hydraulic oil is increased. Then, the hydraulic oil enters the annular groove from the upper side by the blocking action of the cap assembly 460, and finally passes through the oil groove 455 and enters between the bottom of the partition 453 and the bottom wall of the protective case 410.
Referring to fig. 3-4 and 7, the cap assembly 460 includes a cap body 461 disposed over the top of the sleeve 451, the cap body 461 being configured to seal the top opening of the sleeve 451.

The bottom end of the inserted post 464 is fixedly provided with a lower slip ring 466, and the lower slip ring 466 is attached to the outer side wall of the sleeve 451 and the inner side wall of the protective shell 410.
When the hydraulic pressure of the lower cavity in the protective case 410 is increased by the pressurizing assembly 800, or when the hydraulic pressure in the lower cavity is increased by injecting hydraulic oil into the protective case 410 by the oiling assembly 700, the assembly of the lower slip ring 466, the plunger 464 and the upper slip ring 465 is moved upward, the space of the upper cavity is reduced, the hydraulic pressure in the upper cavity is increased, and the deformation of the rubber main spring 420 is suppressed, thereby resisting the downward movement of the piston rod 440.
The assembly of the lower slip ring 466, the post 464, and the upper slip ring 465 moves downward when the hydraulic pressure of the lower cavity in the protective case 410 is reduced by the pressing assembly 800, or when hydraulic oil is pumped from the inside of the protective case 410 by the oil injection assembly 700 to reduce the hydraulic pressure in the lower cavity.
When the assembly of the lower slip ring 466, the post 464 and the upper slip ring 465 moves upward, hydraulic oil between the lower slip ring 466 and the upper slip ring 465 is pushed to move upward synchronously, the hydraulic oil flows upward through a gap between the through hole 463 and the post 464, and an upward thrust is applied to the cap body 461 by a friction force between the hydraulic oil and a wall of the through hole 463, and when the lower slip ring 466 is attached to the bottom of the seal ring 462, an upward thrust is directly applied to the seal ring 462. In this process, the piston rod 440 moves downward, and the pressing plate 441 presses the elastic connection member 470 downward, and applies a downward pushing force to the cap body 461 through the elastic connection member 470.
Similarly, when the assembly of the lower slip ring 466, the post 464, and the upper slip ring 465 moves downward, a downward pushing force is applied to the cap body 461, and in the process, the piston rod 440 moves upward, and an upward pulling force is applied to the cap body 461 through the elastic connection 470.
Thereby adjusting the pressure inside the lower chamber through the pressure applying assembly 800 or the oil filling assembly 700, so that the cap assembly 460 applies a pushing or pulling force to the piston rod 440 to restrain the piston rod 440 from moving.
The cross section of the lower slip ring 466 is in an inverted V shape, and the top edge of the separation barrel 453 is located right below the middle of the lower slip ring 466. The hydraulic oil is thus guided by the lower slip ring 466 to flow each other in the two annular grooves between the outer side wall of the sleeve 451 and the inner side wall of the protective case 410.

Therefore, when the piston rod 440 moves downwards, the second fixing plate 485 moves downwards along the inner wall of the sleeve 451, and simultaneously, through the arrangement of the elastic connecting piece 470, the cylinder cover body 461 is driven to move downwards, so that the hydraulic pressure of the hydraulic oil in the sleeve 451 is increased, and in the process, the hydraulic oil flows through the two groups of vortex-shaped channels. The flow length of the hydraulic oil is extended by the provision of the swirl passage, and the piston plate assembly 480 is restrained from moving downward by the frictional force of the hydraulic oil and the swirl passage.

The mounting plate 600 is fixedly installed at the right side of the top of the air conditioner compressor.
The inside of the base 100 is hollow, and the oil injection assembly 700 is disposed inside the base 100. A sliding groove 503 communicated with the inside of the base 100 is formed in the center of the top of the base, and the sliding groove 503 is parallel to the sliding rail 501. A sliding column 504 is fixedly arranged at the bottom of the sliding seat 502, the sliding column 504 is slidably connected in the sliding groove 503, a transverse plate 505 is fixedly arranged at the bottom of the sliding column 504, and the transverse plate 505 is positioned in the base 100.

The hydraulic oil inside the protective case 410 and the square oil box 701 can flow by the connection of the connection pipe 704. Because square oil box 701 is the platykurtic design, can increase the area of contact with the air, ensure the radiating effect to the hydraulic oil, prevent the high temperature of hydraulic oil in the damping process. Therefore, the flow effect of the hydraulic oil is guaranteed by radiating the hydraulic oil, and a stable damping effect is provided for vibration of the air conditioner compressor.

The output end of the actuator 801 drives the sliding disk 802 to move upwards, so that hydraulic pressure between the bottom of the partition 453 and the bottom wall of the protective shell 410 is increased, and hydraulic oil is driven to flow upwards through the oil groove 455. When the output end of the actuator 801 pulls the slide plate 802 downward, hydraulic oil flows downward through the oil passage 455. Alternatively, the actuator 801 may be replaced with a micro cylinder. An acceleration sensor may be disposed on the base 100 to monitor vibration of the base 100 in a vertical direction, where the acceleration sensor is electrically connected to a processor in the vehicle, and the processor controls the expansion and contraction of the output end of the actuator 801. For example, when the base 100 vibrates downward, the processor controls the output end of the actuator 801 to extend, and the slide plate 802 presses the hydraulic oil inside the protective case 410 to increase the hydraulic pressure and suppress the vibration of the base 100.

The slide seat 502 drives the slide column 504 to slide rightwards along the slide groove 503, the transverse plate 505 synchronously moves rightwards, the slide plate 702 moves rightwards along the square oil box 701 by matching with the connecting action of the connecting rod 703, the hydraulic pressure in the square oil box 701 on the right side is increased, and the hydraulic oil enters the two groups of protection shells 410 on the right side through the connecting pipe 704;
When the piston rod 440 moves toward the inside of the protective shell 410, the pressure plate 441 pushes the metal skeleton 430 and drives the rubber main spring 420 to deform, the rubber main spring 420 elastically resists the piston rod 440 to move toward the inside of the protective shell 410, meanwhile, the lower group of pressure plates 441 presses the spring 473, the elasticity of the spring 473 inhibits the piston rod 440 from moving, the piston plate assembly 480 follows the piston rod 440 to move, the piston plate assembly 480 presses hydraulic oil in the sleeve 451, part of hydraulic oil flows through two groups of vortex channels between the vortex strips one 482 and two 483, and the friction force between the hydraulic oil and the vortex channels inhibits the piston plate assembly 480 from moving in the sleeve 451;
Because the hydraulic oil inside the square oil box 701 passes through the connection pipe 704, between the bottom wall of the protective housing 410 and the bottom of the partition 453, and flows upward through the oil groove 455, into the outer annular groove, then downward through the lower slip ring 466, into the inner annular groove, then through the arc-shaped through groove between the bosses 452, into the sleeve 451, and then through the swirl passage of the piston plate assembly 480, thereby inhibiting the piston plate assembly 480 and the piston rod 440 from moving downward.
And through the hydraulic oil entering the lower cavity, the hydraulic pressure inside the lower cavity is increased, the assemblies of the lower slip ring 466, the insert post 464 and the upper slip ring 465 are driven to move upwards, the space of the upper cavity is reduced, the hydraulic pressure inside the upper cavity is increased, the deformation of the rubber main spring 420 is restrained, so that the downward movement of the piston rod 440 is resisted, meanwhile, the assemblies of the lower slip ring 466, the insert post 464 and the upper slip ring 465 apply upward thrust to the cylinder cover body 461, and when the piston rod 440 moves downwards, the downward thrust applied to the cylinder cover body 461 through the elastic connecting piece 470 is resisted, so that the downward movement of the piston rod 440 is further restrained.
Similarly, when the air-conditioning compressor vibrates vertically, the base 100 vibrates vertically at the same time, the protective housing 410 of the secondary suspension moves downward relative to the piston rod 440, and meanwhile, the output end of the actuator 801 extends to drive the sliding disc 802 to slide in the protective housing 410, so that the hydraulic pressure of hydraulic oil between the bottom of the separation tube 453 and the bottom wall of the protective housing 410 is increased, and the relative movement between the protective housing 410 and the piston rod 440 is suppressed.
