Description

Technical Field

[0001] This utility model relates to the field of shock absorber technology, and more specifically, to a built-in adjustable damping shock absorber. Background Technology

[0002] A damping shock absorber is a device that converts vibration kinetic energy into heat energy or other forms of energy. It is commonly used in automobile shock absorption. It dissipates the vibration energy of the automobile structure through the friction or resistance of the damping material, reduces the risk of resonance, protects the automobile structure from vibration damage, significantly extends its service life, and improves the driving comfort of the automobile.

[0003] Based on the above, the inventors have discovered that existing damping shock absorbers are installed after the damping is adjusted. However, the road conditions in which cars travel are complex and unpredictable, and the damping requirements of shock absorbers vary under different driving conditions. Although the damping of some car shock absorbers can be manually adjusted, the operation is very troublesome and laborious. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a built-in adjustable damping shock absorber, in order to achieve a more practical purpose. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a built-in adjustable damping shock absorber. This solution uses an electromagnetic adjustment component to adjust the damping, enabling the vehicle to adjust the damping of the suspension system in real time according to different driving environments and driving needs, thereby optimizing handling and comfort. Furthermore, a guide component is set up to guide the movement of the adjustment component and reduces the movement resistance through rotation, thereby improving the movement stability of the adjustment component and ensuring the damping adjustment effect.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] An internally mounted adjustable damping shock absorber includes an upper support base and a lower support base. A spring and a protective sleeve are fixedly connected to the opposite surfaces of the upper and lower support bases. A piston rod is fixedly connected to the bottom of the upper support base. A piston valve is fixedly connected to the bottom end of the piston rod. An oil guide hole is provided inside the piston valve. A liquid storage pipe is fixedly connected to the top surface of the lower support base. An electromagnetic ring is sleeved on the outside of the liquid storage pipe. A support rod and a wire are fixedly connected to both ends of the electromagnetic ring, and a set of guide mechanisms is provided on the side of the electromagnetic ring.

[0009] The guiding mechanism includes a sliding sleeve, a guide rod is provided through the inside of the sliding sleeve, and several sets of movable balls are movably connected inside the sliding sleeve. A set of guide grooves is provided on the outer side of the guide rod.

[0010] Furthermore, the upper support and the lower support are symmetrically arranged, and both the outer side of the upper support and the outer side of the lower support are fixedly connected with lifting lugs.

[0011] Furthermore, the protective sleeve is located outside the piston rod and the liquid reservoir, and the spring is located outside the protective sleeve.

[0012] Furthermore, the upper end of the support rod and the upper end of the wire are both fixedly connected to the upper support base, and the wire passes through the upper support base.

[0013] Furthermore, the interior of the liquid storage tube is filled with magnetorheological fluid, which is compatible with the electromagnetic ring.

[0016] 3. Beneficial Effects

[0017] Compared with existing technologies, the advantages of this utility model are:

[0018] (1) This solution uses the upper support seat to drive the support rod and the electromagnetic ring to move synchronously, ensuring that the electromagnetic ring is located outside the piston valve. At the same time, the electromagnetic strength is adjusted by adjusting the electromagnetic ring through the wire, changing the resistance of the magnetorheological fluid when passing through the oil guide hole. Compared with the existing technology, by setting the electromagnetic adjustment component to adjust the damping, the vehicle can adjust the damping of the suspension system in real time according to different driving environments and driving needs, thus optimizing the handling and comfort.

[0019] (2) By setting a guide mechanism, the movement of the electromagnetic ring drives the sliding sleeve to slide on the outside of the guide rod. At this time, the movable ball rubs against the guide groove and the movable ball rotates, reducing the moving resistance of the sliding sleeve. Compared with the prior art, the guide component plays a role in guiding the movement of the adjustment component and reduces the moving resistance by rotating, thereby improving the moving stability of the adjustment component and ensuring the damping adjustment effect.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Example:

[0027] Please see Figure 1-4 An adjustable damping shock absorber with built-in damping includes an upper support base 1 and a lower support base 2. A spring 4 and a protective sleeve 5 are fixedly connected to the opposite surfaces of the upper support base 1 and the lower support base 2. A piston rod 6 is fixedly connected to the bottom of the upper support base 1. A piston valve 7 is fixedly connected to the bottom end of the piston rod 6. An oil guide hole 8 is opened inside the piston valve 7. A liquid storage pipe 17 is fixedly connected to the top surface of the lower support base 2. An electromagnetic ring 9 is sleeved on the outside of the liquid storage pipe 17. A support rod 10 and a wire 11 are fixedly connected to both ends of the electromagnetic ring 9, and a set of guide mechanisms 12 is provided on the side of the electromagnetic ring 9.

[0028] The guide mechanism 12 includes a sliding sleeve 13, a guide rod 14 is provided through the inside of the sliding sleeve 13, and several sets of movable balls 15 are movably connected inside the sliding sleeve 13. A set of guide grooves 16 are provided on the outside of the guide rod 14. The guide mechanism 12 is provided to ensure the movement stability of the electromagnetic ring 9.

[0029] See Figure 1 The upper support 1 and the lower support 2 are symmetrically arranged, and the outer side of the upper support 1 and the outer side of the lower support 2 are both fixedly connected with lifting lugs 3. The shock absorber is installed and fixed by the cooperation of the two lifting lugs 3.

[0030] See Figure 1The protective sleeve 5 is located outside the piston rod 6 and the liquid storage tube 17, and the spring 4 is located outside the protective sleeve 5. When vibration occurs, the gap between the upper support seat 1 and the lower support seat 2 is adjusted, thereby causing the protective sleeve 5 and the spring 4 to deform.

[0031] See Figure 2 The upper end of the support rod 10 and the upper end of the wire 11 are both fixedly connected to the upper support seat 1, and the wire 11 passes through the upper support seat 1. The piston rod 6 drives the piston valve 7 to move inside the liquid storage tube 17, and at the same time drives the support rod 10 to move.

[0032] See Figure 2 The inside of the reservoir 17 is filled with magnetorheological fluid, which is compatible with the electromagnetic ring 9. The movement of the piston valve 7 causes the magnetorheological fluid inside the reservoir 17 to pass through the oil guide hole 8. At this time, the friction between the hole wall and the magnetorheological fluid and the internal friction between the oil molecules form a damping force on the vibration, which converts the vibration energy of the car into the heat energy of the oil and then dissipates it into the atmosphere.

[0033] See Figure 3 The two ends of the guide rod 14 are fixedly connected to the lower support 2 and the liquid storage tube 17 respectively. The sliding sleeve 13 is fixedly connected to the electromagnetic ring 9. The movement of the electromagnetic ring 9 causes the sliding sleeve 13 to slide on the outside of the guide rod 14.

[0034] See Figure 4 The movable ball 15 and the guide groove 16 are arranged in a ring array, and one side of the movable ball 15 is in contact with the guide groove 16. The movable ball 15 rubs against the guide groove 16 and rotates, reducing the moving resistance of the sliding sleeve 13 and ensuring the moving stability of the electromagnetic ring 9.

[0035] In use: The shock absorber is installed and fixed by the cooperation of two lifting lugs 3. When the car structure vibrates, the gap between the upper support 1 and the lower support 2 is adjusted, which causes the protective sleeve 5 and the spring 4 to deform. At the same time, the piston rod 6 drives the piston valve 7 to move inside the reservoir 17. The movement of the piston valve 7 causes the magnetorheological fluid inside the reservoir 17 to pass through the oil guide hole 8. At this time, the friction between the hole wall and the magnetorheological fluid and the internal friction between the oil molecules form a damping force on the vibration, which converts the vibration energy of the car into the heat energy of the oil and then dissipates it into the atmosphere. In the middle, it plays a role in shock absorption. At the same time, the upper support seat 1 drives the support rod 10 and the electromagnetic ring 9 to move synchronously, so that the electromagnetic ring 9 is located outside the piston valve 7. Meanwhile, the electromagnetic strength of the electromagnetic ring 9 is adjusted by the wire 11, which changes the resistance of the magnetorheological fluid when it passes through the oil guide hole 8, thereby adjusting the damping. The movement of the electromagnetic ring 9 causes the sliding sleeve 13 to slide outside the guide rod 14. At this time, the movable ball 15 rubs against the guide groove 16, and the movable ball 15 rotates, reducing the moving resistance of the sliding sleeve 13 and ensuring the moving stability of the electromagnetic ring 9.
