Compact slide rail damper

Abstract

The utility model discloses a compact type sliding rail damper, which relates to the technical field of dampers and comprises a sleeve, an electromagnetic damping cavity is arranged on one side of an inner cavity of the sleeve, a pressure bearing groove is arranged on the other side of the inner cavity of the sleeve, an oil storage groove is arranged on one side of the pressure bearing groove, and the lower end of an inner cavity of the oil storage groove is communicated with an inner cavity of the pressure bearing groove. The inner wall of the electromagnetic damping cavity is fixedly connected with a sliding rail. Through the arrangement of the pressure-bearing groove and the electromagnetic damping cavity, when the damper works and the stress is small, the damping function is completed through the viscosity that hydraulic oil in the pressure-bearing groove gradually flows into the oil storage groove, the sensitivity is high, and when the stress is large or the stress time is long, the pressing block pushes the multiple strong magnetic plates to move downwards along the sliding rail, so that the strong magnetic plates move downwards along the sliding rail. When the pressing rod moves downwards, the pressing rod needs to overcome the magnetic force and the viscous force of hydraulic oil at the same time through the homopolar repulsive force among the strong magnetic plates, and therefore the bearing capacity of the damper is enhanced, and the high sensitivity is achieved while the large bearing capacity is achieved.

Description

Technical Field

[0001] The utility model relates to the technical field of dampers, in particular to a compact slide rail damper. Background Art

[0002] A damper is a device that provides resistance to motion and dissipates motion energy. In industries such as aerospace, aviation, military, guns, and automobiles, various dampers have long been used to reduce vibration and dissipate energy, and it is a device that can quickly stop the movable part of an instrument at a stable deflection position. In seismic instruments, dampers are used to absorb the inherent vibration energy of the vibration system, and its damping force is generally proportional to the velocity of the motion of the vibration system. There are mainly three types: liquid dampers, gas dampers, and electromagnetic dampers. Dampers play an important role in compensating for the very small friction and air resistance in the pendulum system of a pickup, and improving the frequency response, etc.

[0003] At present, for the dampers on the market, their bearing capacity is constant. For dampers with a high bearing capacity, the damper pressure rod needs to be subjected to a large pressure to make the damper contract and consume energy, and the damping sensitivity is relatively low. While for dampers with a small bearing capacity, although the damping sensitivity has been improved to a certain extent, their bearing capacity is low, and there are certain inconveniences in use. Content of the Utility Model

[0004] The utility model provides a compact slide rail damper to solve the problems raised in the above background art.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A compact slide rail damper includes a sleeve. On one side of the inner cavity of the sleeve, there is an electromagnetic damping cavity.

The lower end of the inner cavity of the oil storage groove is communicated with the inner cavity of the pressure-bearing groove. The inner wall of the electromagnetic damping cavity is fixedly connected with a slide rail.

[0007] A further improvement of the technical solution of the utility model is that: the top of the sleeve is fixedly connected with a sealing plate. Inside the sealing plate, there is a primary pressure rod slidingly connected. The lower end of the primary pressure rod is fixedly connected with a first piston. The inner wall of the oil storage groove is lapped with a second piston wearing a heavy block.

[0008] A further improvement of the technical solution of the utility model is that: the surface of the first piston is lapped with the inner wall of the pressure-bearing groove. The top of the primary pressure rod is fixedly connected with a connecting block.

[0009] A further improvement of the technical solution of the utility model is that: the top of the connecting block is fixedly connected with a first connecting ring. On one side of the bottom of the connecting block, there is a reinforcing pressure rod fixedly connected.

[0010] A further improvement of the technical solution of the present utility model lies in that: a pressing block is fixedly connected to the bottom of the reinforcing pressing rod, and the surface of the pressing block is slidably connected to the surface of the slide rail.

[0011] A further improvement of the technical solution of the present utility model lies in that: a strong magnetic plate is arranged below the pressing block, the adjacent surfaces of the four strong magnetic plates are of the same pole, and the surface of the strong magnetic plate is slidably connected to the surface of the slide rail.

[0014] Due to the adoption of the above technical solution, the technical progress achieved by the present utility model compared with the prior art is:

[0015] The present utility model provides a compact slide rail damper. Through the arrangement of the pressure-bearing groove and the electromagnetic damping cavity, when the damper works, when the force is small, the damping function is completed through the viscosity of the hydraulic oil in the pressure-bearing groove gradually flowing into the oil storage tank, and the sensitivity is relatively high. When the force is large or the force application time is long, the pressing block pushes multiple strong magnetic plates to move downward along the slide rail. By using the repulsive force between the same poles of the multiple strong magnetic plates, when the pressing rod moves downward, it is necessary to overcome the magnetic force and the viscosity of the hydraulic oil at the same time, thereby enhancing the bearing capacity of the damper, making it have a large bearing capacity while having a relatively high sensitivity.

Detailed implementation mode

[0022] The following further describes the present utility model in detail in conjunction with embodiments: Embodiment

[0023] As Figures 1-5 shown, the present utility model provides a compact slide rail damper, including a sleeve 1. On one side of the inner cavity of the sleeve 1, there is an electromagnetic damping chamber 2. On the other side of the inner cavity of the sleeve 1, there is a pressure-bearing groove 3. On one side of the pressure-bearing groove 3, there is an oil storage tank 4. The lower end of the inner cavity of the oil storage tank 4 is communicated with the inner cavity of the pressure-bearing groove 3. The inner wall of the electromagnetic damping chamber 2 is fixedly connected with a slide rail 5.

[0024] In this embodiment, when the force is relatively large, the connecting block 15 continuously moves downward, so that the reinforcing pressure rod 10 pushes the pressure block 11 to slide downward along the slide rail 5 and contacts the strong magnetic plate 12, pressing the strong magnetic plate 12 downward along the slide rail 5. When the connecting block 15 moves downward, it is necessary to overcome the viscosity of the hydraulic oil and the like-pole repulsion force between the strong magnetic plates 12 at the same time, thereby enhancing the bearing capacity of the damper, making it have good damping sensitivity while also having a large bearing capacity. Embodiment

[0025] As Figures 1-5 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, on one side of the inner cavity of the sleeve 1, there is an electromagnetic damping chamber 2. On the other side of the inner cavity of the sleeve 1, there is a pressure-bearing groove 3. On one side of the pressure-bearing groove 3, there is an oil storage tank 4. The lower end of the inner cavity of the oil storage tank 4 is communicated with the inner cavity of the pressure-bearing groove 3. The inner wall of the electromagnetic damping chamber 2 is fixedly connected with a slide rail 5. The top of the sleeve 1 is fixedly connected with a sealing plate 6. The inside of the sealing plate 6 is slidably connected with a primary pressure rod 7. The lower end of the primary pressure rod 7 is fixedly connected with a first piston 8. The inner wall of the oil storage tank 4 is lapped with a second piston 9 wearing a heavy block. The surface of the first piston 8 is lapped with the inner wall of the pressure-bearing groove 3. The top of the primary pressure rod 7 is fixedly connected with a connecting block 15. The top of the connecting block 15 is fixedly connected with a first connecting ring 16. One side of the bottom of the connecting block 15 is fixedly connected with a reinforcing pressure rod 10.

[0026] In this embodiment, when the damper is stressed, the first connecting ring 16 pushes the connecting block 15 downward, causing the primary pressure rod 7 and the reinforcing pressure rod 10 to move downward simultaneously. Under the action of the primary pressure rod 7, the first piston 8 is pushed to slide along the inner wall of the pressure-bearing groove 3, so that the hydraulic oil in the pressure-bearing groove 3 enters the oil storage groove 4. The pressure received by the damper is consumed by the viscosity of the flowing hydraulic oil. When the stress is large, the connecting block 15 continues to move downward, causing the reinforcing pressure rod 10 to push the pressing block 11 to slide downward along the slide rail 5 and contact the strong magnetic plate 12, pressing the strong magnetic plate 12 downward along the slide rail 5. During the process of the connecting block 15 moving downward, it is necessary to overcome the viscosity of the hydraulic oil and the like-pole repulsion force between the strong magnetic plates 12 at the same time, thereby enhancing the bearing capacity of the damper. While having good damping sensitivity, it also has a large bearing capacity. Embodiment

[0027] As Figures 1-5 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, an electromagnetic damping cavity 2 is provided on one side of the inner cavity of the sleeve 1, a pressure-bearing groove 3 is provided on the other side of the inner cavity of the sleeve 1, an oil storage groove 4 is provided on one side of the pressure-bearing groove 3, the lower end of the inner cavity of the oil storage groove 4 is communicated with the inner cavity of the pressure-bearing groove 3, a slide rail 5 is fixedly connected to the inner wall of the electromagnetic damping cavity 2, a pressing block 11 is fixedly connected to the bottom of the reinforcing pressure rod 10, the surface of the pressing block 11 is slidably connected to the surface of the slide rail 5, a strong magnetic plate 12 is arranged below the pressing block 11, the adjacent surfaces of the four strong magnetic plates 12 are of the same pole, the surface of the strong magnetic plate 12 is slidably connected to the surface of the slide rail 5, an electromagnet 13 is fixedly connected below the strong magnetic plate 12, a wire 14 for supplying power to the electromagnet is arranged on one side of the electromagnet 13, a second connecting ring 17 is fixedly connected to the bottom of the sleeve 1, and the inside of the sleeve 1 is in contact with the surface of the wire 14.

[0028] In this embodiment, when the stress is large, the connecting block 15 continues to move downward, causing the reinforcing pressure rod 10 to push the pressing block 11 to slide downward along the slide rail 5 and contact the strong magnetic plate 12, pressing the strong magnetic plate 12 downward along the slide rail 5. During the process of the connecting block 15 moving downward, it is necessary to overcome the viscosity of the hydraulic oil and the like-pole repulsion force between the strong magnetic plates 12 at the same time, thereby enhancing the bearing capacity of the damper. While having good damping sensitivity, it also has a large bearing capacity. The setting of the electromagnet 13 can make the electromagnet 13 have a large repulsive force with the upper strong magnetic plate 12 by energizing the wire 14, thereby enhancing the bearing capacity of the damper again.

[0029] Next, the working principle of the compact slide rail damper will be specifically described.

[0030] As Figures 1-5As shown, when the damper is under force, the first connecting ring 16 pushes the connecting block 15 downward, causing the primary pressure rod 7 and the reinforcing pressure rod 10 to move downward simultaneously. Under the action of the primary pressure rod 7, the first piston 8 is pushed to slide along the inner wall of the pressure-bearing groove 3, causing the hydraulic oil in the pressure-bearing groove 3 to enter the oil storage groove 4. The pressure received by the damper is consumed through the viscosity of the flowing hydraulic oil. When the force is relatively large, the connecting block 15 continues to move downward, causing the reinforcing pressure rod 10 to push the pressing block 11 to slide downward along the slide rail 5 and come into contact with the strong magnetic plate 12, pressing the strong magnetic plate 12 downward along the slide rail 5. During the process of the connecting block 15 moving downward, it is necessary to overcome the viscosity of the hydraulic oil and the like-pole repulsive force between the strong magnetic plates 12 at the same time, thereby enhancing the bearing capacity of the damper. While having good damping sensitivity, it also has a large bearing capacity. At the same time, the setting of the electromagnet 13 can, by energizing the wire 14, make the electromagnet 13 have a large repulsive force with the upper strong magnetic plate 12, thereby enhancing the bearing capacity of the damper again.
