Abstract
Description
Technical Field
[0001] This utility model relates to the field of vibration damper valve system technology, and in particular to a composite functional vibration damper valve system. Background Technology
[0002] Traditional shock absorber valve systems mostly employ a fixed valve core structure, whose damping characteristics rely on a preset valve opening degree and cannot be dynamically adjusted according to actual vibration frequency or load changes. Especially under complex working conditions (such as road impacts during high-speed driving or sudden load changes), a single damping mode can easily lead to delayed damping effect or excessive energy consumption. In addition, existing valve systems mostly rely on mechanical levers or hydraulic feedback for adjustment, resulting in slow response speed and limited adjustment accuracy, making it difficult to meet the requirements of high-precision vibration damping. Although some designs have attempted to introduce electric drive, problems such as complex structure, poor sealing, or limited adjustment range lead to insufficient reliability in practical applications. Utility Model Content

[0006] The adjusting mechanism includes a piston block, a first valve core, a second valve core, a rotating ring, and a rotating shaft. The piston block has a guide groove around its bottom periphery and is slidably installed inside the valve system housing. Several first valve cores and second valve cores are embedded around the axis in the piston block. A rotating shaft is rotatably installed at the bottom of the piston block, and several rotating rings are sleeved on the rotating shaft. Sliding sealing blocks are fixedly installed on each of the rotating rings. The ends of the sliding sealing blocks away from the rotating rings are slidably installed in the grooves of the piston block.

Detailed Implementation
[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0025] like Figure 1-7 As shown, the composite functional shock absorber valve system includes a valve system housing 1, an upper end cover 2 fixedly connected to the top of the valve system housing 1, a lower end cover 5 fixedly connected to the bottom of the valve system housing 1, an adjustment mechanism 9 slidably installed inside the valve system housing 1, and a power mechanism 8 installed on the bottom surface of the lower end cover 5.
[0026] The adjusting mechanism 9 includes a piston block 901, a first valve core 902, a second valve core 903, a rotating ring 904, and a rotating shaft 905. The piston block 901 has a guide groove around its bottom periphery. The piston block 901 is slidably installed inside the valve system housing 1. Several first valve cores 902 and second valve cores 903 are embedded around the axis in the piston block 901. The rotating shaft 905 is rotatably installed at the bottom of the piston block 901. Several rotating rings 904 are sleeved on the rotating shaft 905. Sliding sealing blocks 909 are fixedly installed on the rotating rings 904 respectively. The ends of the sliding sealing blocks 909 away from the rotating rings 904 are slidably installed in the grooves of the piston block 901. The first valve core 902, the second valve core 903, and the sliding sealing blocks 909 are radially corresponding.
[0027] In this embodiment, the bottom surface of the piston block 901 is provided with several fixed blocks 911, which correspond to the positions of the first valve core 902. A stop post 910 is fixedly installed on the bottom surface of several sliding sealing blocks 909. A sleeve 906 is fixedly installed on one side surface of the rotating shaft 905. A return spring is provided inside the sleeve 906, one end of which is connected to a shaft post 907. One end of the shaft post 907 rotatably passes through the sleeve 906. A toggle block 908 is fixedly installed on the top surface of the shaft post 907, and the toggle block 908 overlaps with the stop post 910. The several sliding sealing blocks 909 slide and seal with the bottom surfaces of the first valve core 902 and the second valve core 903. The fixed blocks 911 correspond to the positions of the first valve core 902, providing mechanical limits for the toggle block 908 and preventing excessive movement of the sliding sealing blocks 909 that could lead to sealing failure. The stop post 910 acts as a transmission medium, converting the linear displacement of the toggle block into the radial displacement of the sliding sealing block. The return spring inside sleeve 906 is linked to shaft 907 to ensure that the actuating block 908 automatically resets after passing stop 910, preventing loss of adjustment state due to motor stoppage or power interruption. The sliding seal stop 909 cooperates with the sliding seal of the valve core, compensating for machining errors through elastic deformation, and is guided by the guide groove of piston block 901 to ensure a constant contact area of the sealing surface, improving sealing reliability under high pressure conditions.
[0028] In this embodiment, the power mechanism 8 includes a column 81, a fixing plate 82, and a motor 83. Two columns 81 are fixedly installed on the bottom surface of the lower end cover 5. Anti-detachment limiting plates 84 are fixedly installed on the bottom ends of the two columns 81. The fixing plate 82 is slidably installed through the two columns 81. The motor 83 is fixedly installed on the fixing plate 82. An output gear 85 is fixedly sleeved at the output end of the motor 83. A lower rotating column 7 is fixedly installed on the bottom surface of the rotating shaft 905. The bottom end of the lower rotating column 7 rotatably passes through the lower end cover 5 and is fixedly sleeved with a first gear 87. The first gear 87 meshes with the output gear 85. Limiting rings 86 are fixedly installed on both the top and bottom surfaces of the first gear 87. The column 81 and the limiting ring 86 form a vertical limit to prevent the first gear 87 from moving axially; the meshing transmission between the output gear 85 and the first gear 87 accurately transmits the rotational motion of the motor to the rotating shaft 905, reducing torque loss. At the same time, the anti-disengagement limiting plate 84 can drive the motor 83 to move up and down, so as to provide continuous power.
[0029] In this embodiment, a connecting column 4 is fixedly installed on the top of the adjusting mechanism 9, and the top end of the connecting column 4 slides through the upper end cover 2. Several support plates 6 are fixedly installed on the bottom end of the valve system housing 1, and support seats 3 are fixedly installed on the bottom ends of the several support plates 6. The connecting column 4 serves as a guide component for the piston block 901, ensuring that it slides linearly along the valve system housing 1; the support plates 6 and support seats 3 distribute the load-bearing pressure of the lower end cover 5, enhancing the overall structural stability.
[0030] Working principle: When the motor 83 starts, the output gear 85 drives the first gear 87 to rotate, which in turn drives the lower rotating column 7 and the rotating shaft 905 to rotate synchronously. The sleeve 906 on the rotating shaft 905 swings with the shaft, and the internal return spring pushes the actuating block 908 to slide along the stop column 910 through the shaft column 907.
[0031] Clockwise rotation: The actuating block 908 pushes the stop pins 910 in sequence, causing the sliding sealing stop block 909 to move inward along the groove of the piston block 901, covering the corresponding first valve core 902 and second valve core 903, blocking the fluid passage. When the actuating block 908 slides past the fixed stop block 911, the shaft 907 is forced to rotate due to the stop block's limitation. The return spring releases its elastic potential energy, driving the actuating block to switch to the next stop pin 910, realizing multi-level continuous adjustment.
[0032] Counterclockwise rotation: The actuating block 908 moves the sliding sealing block 909 outward in the opposite direction, gradually releasing the seal on the valve core and increasing the fluid flow area. During adjustment, the radial correspondence between the sliding sealing block 909 and the valve core ensures uniform contact of the sealing surface, avoiding localized wear.
[0033] The fixed stop 911 corresponds to the position of the first valve core 902, providing a mechanical limit for the actuating block 908 and preventing the sliding sealing stop 909 from moving excessively and causing sealing failure; the stop post 910 serves as a transmission medium, converting the linear displacement of the actuating block into the radial displacement of the sliding sealing stop.
[0034] The return spring inside the sleeve 906 is linked with the shaft 907 to ensure that the actuating block 908 automatically resets after passing the stop 910, and can realize the position adjustment of all sliding sealing stops 909 by a single actuating block 908.
[0035] The sliding sealing block 909 is in sliding sealing cooperation with the valve core. It compensates for machining errors through elastic deformation, and at the same time, it uses the guide groove of the piston block 901 to guide the flow, ensuring that the contact area of the sealing surface is constant and improving the sealing reliability under high pressure conditions.
[0036] The circuits, electronic components, and control modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon.
