Description

Technical Field

[0001] The invention relates to the field of vibration isolation technology, and more particularly to a vibration isolation device with a self-resetting function. Background Art

[0002] A vibration isolation device is a device used to reduce or isolate vibration transmission. It is mainly used in many fields such as mechanical engineering, construction engineering, transportation, etc. Its basic function is to absorb, attenuate or reflect vibration energy through its own structure and material properties, thereby reducing the impact of vibration on equipment or structures.

[0003] In the field of modern transportation, whether it is trucks and buses for road transportation, trains for rail transportation, or various precision instruments and equipment, shock absorption and protection during transportation are crucial. During transportation, the road conditions are complex and changeable, and vehicles will encounter various vibrations. Among them, low-frequency vibrations mainly come from vehicles driving on relatively flat but undulating roads, such as gentle slopes and slight unevenness on ordinary roads. The vibration amplitude is relatively large but the frequency is low; while high-frequency vibrations are mostly caused by tiny defects in the road surface when the vehicle is driving at high speed, such as small stones and slight joints on the road surface, and the vibration frequency is high and relatively rapid.

[0004] There are many kinds of vibration isolators that we use daily, many of which have self-resetting functions. Among them, spring vibration isolators are the most common. Spring vibration isolators mainly use the elastic deformation of the spring to absorb vibration energy. The stiffness and damping characteristics of the spring determine the vibration isolation effect. The advantages are large load-bearing capacity and good low-frequency vibration isolation effect; the disadvantages are that it is easy to resonate, and the vibration isolation effect decreases at high frequencies, and it cannot be continuously applied to high-frequency vibration isolation. When the transportation road conditions change, the vibration frequency changes from low frequency to high frequency, and its vibration isolation effect will be greatly reduced. In the long run, the transported goods or equipment will be easily damaged, affecting the safety of transportation and the integrity of the goods.

[0016] The beneficial effects of the present invention are:

[0017] 1. The vibration isolation device with a self-resetting function described in the present invention can make the pressure plate and the mounting cylinder suitable for low-frequency vibrations during transportation through a supporting mechanism. When high-frequency vibrations occur during transportation, the frequency of the vibrations increases, the friction speed between the friction block and the friction box increases, and the heat that can be quickly generated increases. The first threaded plate can be effectively moved with the help of heat, and the high-pressure nitrogen filled in the air storage tank can be squeezed with the help of the first threaded plate, so that the high-pressure nitrogen is compressed into the cylinder body. Increasing the amount of high-pressure nitrogen in the cylinder body will increase its natural frequency, which helps to make more high-frequency vibrations fall outside the effective frequency range of vibration isolation, thereby improving the high-frequency vibration isolation efficiency. In this way, high-frequency vibration isolation or low-frequency vibration isolation can be automatically switched according to the need of vibration isolation during transportation, and the scope of application is wider, and it can be suitable for transportation on different road surfaces.

[0018] 2. The vibration isolation device with self-resetting function described in the present invention increases the amount of high-pressure nitrogen in the cylinder by compressing high-pressure nitrogen, and also increases the amount of high-pressure nitrogen in the piston rod. With the help of air pressure, the blocking column can be moved, and the moving blocking column will block part of the damping hole. From the perspective of energy absorption, reducing the damping hole will cause the oil to be subjected to greater viscous resistance when flowing through the rubber ring. Under high-frequency vibration, this greater resistance can more effectively convert vibration energy into heat energy, thereby better absorbing high-frequency vibration energy, and can be effectively applied to the effect of high-frequency vibration isolation.

[0019] 3. The vibration isolation device with a self-resetting function described in the present invention can drive the friction block to move continuously inside the friction box through the continuous up and down compression movement of the pressure plate. Each movement of the friction box will extract and discharge the heat in the installation frame to ensure that the heat of the pressure plate does not accumulate during the low-frequency vibration process and no heat acts on the bimetallic strip. However, when the high-frequency vibration is too fast, the heat increases rapidly and cannot be dissipated quickly, thereby acting on the bimetallic strip. In this way, the vibration isolation mode can be effectively switched according to the frequency of vibration, and the extracted gas will also be discharged through the hollow heat sink, which can dissipate heat for the support mechanism to avoid excessive temperature and reduce the vibration isolation effect. The hollow heat sink will also swing continuously, so that the exhausted gas can be blown to different positions of the support mechanism and accelerate the flow of air inside and outside the installation cylinder.

DETAILED DESCRIPTION

[0033] The subject matter described herein will now be discussed with reference to example implementations. It should be understood that the discussion of these implementations is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Various examples may omit, replace, or add various processes or components as needed. In addition, the features described in some examples may also be combined in other examples.

[0034] like Figure 1 to Figure 2 , Fig.11As shown, a vibration isolation device with a self-resetting function according to an embodiment of the present invention comprises a mounting tube 2 with a plurality of through holes, a pressurizing mechanism is fixedly mounted at the bottom of the inner cavity of the mounting tube 2, the pressurizing mechanism comprises a support column 315, a mounting groove 314 is formed on the support column 315, a support mechanism is fixedly connected inside the mounting groove 314, an air delivery pipe 705 is fixedly connected to the support mechanism, the air delivery pipe 705 is fixedly connected to the support column 315 and extends to the inside of the air storage tank 313, a pressure plate 1 is fixedly connected to the top of the support mechanism; the support mechanism comprises a cylinder body 702, the bottom end of the cylinder body 702 is located at The interior of the mounting groove 314 is fixedly connected to the support column 315, and a floating piston 707 is slidably connected to the interior of the cylinder body 702. A pressure relief assembly is arranged above the floating piston 707, and the pressure relief assembly passes through the cylinder body 702 and is slidably connected to the cylinder body 702. A mounting cover 701 is fixedly connected to the top of the pressure relief assembly, and the mounting cover 701 is fixedly connected to the pressure plate 1, and the mounting cover 701 is slidably connected to the mounting cylinder 2; a fixing sleeve is fixedly connected to the cylinder body 702, and the fixing sleeve is connected to the mounting cover 701 through a first spring 703; a connecting plate 8 is fixedly connected to the top of the pressure plate 1 and the bottom of the mounting cylinder 2;

[0035] It should be noted that the device can be installed on the transport device through the connection plate 8, one connection plate 8 is connected to the placement platform of the transport device, and the other connection plate 8 is connected to the moving part of the transport device. The two connection plates 8 can also be connected to the two placement platforms respectively, so as to achieve a vibration isolation effect at the placement platform.

[0036] When low-frequency vibration occurs, the pressure plate 1 will move toward the mounting cylinder 2, thereby pressing down the first spring 703, and in this process, the piston rod 706 will also drive the rubber ring 711 to move downward. The downward movement of the rubber ring 711 will squeeze the oil, and part of the oil will move to the top of the rubber ring 711 through the damping hole 708, while part of the oil will squeeze the floating piston 707, and the floating piston 707 will squeeze the high-pressure nitrogen, thereby consuming energy with the help of the resistance in the squeezing process, thereby achieving the effect of low-frequency shock absorption.

[0037] Please refer to Figure 5 , Figures 7 and 8A friction drive mechanism is fixedly installed on the mounting cylinder 2, and the friction drive mechanism includes a fixed frame 401, which is fixedly connected to the mounting cylinder 2; friction boxes 408 are fixedly connected on both sides of the mounting frame, and a friction plate 404 is slidably connected inside the friction box 408, and a driving plate 414 is fixedly connected to the top of the friction plate 404, and the driving plate 414 is fixedly connected to the pressure plate 1; the friction drive mechanism also includes a heat absorbing plate 411, which is fixedly connected to the friction box 408, and a bimetallic strip 409 is fixedly connected to the heat absorbing plate 411, and grooves are provided on the bimetallic strip 409 and the heat absorbing plate 411. A pulling rope 412 is arranged inside the groove, and a limited position seat 413 is slidably connected to the pulling rope 412, and the limited position seat 413 is fixedly connected to the friction box 408; one end of the pulling rope 412 is fixedly connected to the bimetallic strip 409, and the other end of the pulling rope 412 is fixedly connected to the partition plate 405, and the partition plate 405 is slidably connected to the fixed frame 401, and the partition plate 405 is slidably connected to the friction box 408 through the fifth spring; a first magnetic plate 403 is arranged above the partition plate 405, and the first magnetic plate 403 is embedded in the fixed frame 401; a plurality of one-way exhaust pipes 407 are fixedly installed on the fixed frame 401; a mounting frame is arranged below There is a driving mechanism, which includes a first screw 302, the first screw 302 is rotatably connected to the mounting cylinder 2, a worm wheel 301 is fixedly connected to the first screw 302, a worm 304 is meshed on the worm wheel 301, a fixing plate 309 is rotatably connected to the worm 304, the fixing plate 309 is fixedly connected to the mounting cylinder 2, a first rotating shaft 307 is rotatably connected to the fixing plate 309, the first rotating shaft 307 and the worm 304 are both fixedly connected with a pulley 306, the two pulleys 306 are connected by a connecting belt 305, a first gear 303 is fixedly connected to the first rotating shaft 307, and the first gear 303 is fixedly connected to the first gear 303. A driving frame 402 is provided, and a plurality of latch teeth 410 are fixedly connected to the driving frame 402, and the latch teeth 410 are meshed with the first gear 303. The driving frame 402 is slidably connected to the fixed frame 401, and a second magnetic plate 406 is fixedly connected to the top of the driving frame 402, and the first magnetic plate 403 and the second magnetic plate 406 are magnetically repelled from each other. The bottom of the driving frame 402 is connected to the mounting cylinder 2 through a sixth spring 415; the driving mechanism also includes a plurality of first sprocket wheels 311, and the plurality of first sprocket wheels 311 are respectively fixedly connected to the first screw rod 302 and the second screw rod 310, and the plurality of first sprocket wheels 311 are connected through a first chain 312;

[0038] When the pressure plate 1 is close to the mounting cylinder 2 due to vibration, the pressure plate 1 will also drive the driving plate 414 and the friction plate 404 to move. The friction plate 404 moves inside the friction box 408 and will continuously rub against the friction box 408, thereby generating heat, which will be absorbed by the bimetallic strip 409 in contact with it. When the pressure plate 1 is acted on by low-frequency vibration, the friction plate 404 moves slowly and moves a short distance. The heat generated by friction will be dispersed and cannot be concentrated on the bimetallic strip 409. In addition, during the up and down movement of the friction plate 404, the generated heat can be largely extracted through the one-way exhaust pipe 407 to avoid the heat from acting on the bimetallic strip 409. In this way, when the device is in a low-frequency state, it will continue to work in the current state; when encountering high-frequency vibration, the friction plate 404 moves faster and its distance becomes shorter, and it is only concentrated on The bimetallic strip 409 is rubbed quickly, so that all the heat generated will act on the bimetallic strip 409, greatly reducing heat waste, and due to the high speed, the heat is generated quickly, and the bimetallic strip 409 can be bent quickly. When the bimetallic strip 409 is bent, the bimetallic strip 409 will pull the pull rope 412, and the pull rope 412 will pull the partition plate 405, and the partition plate 405 will move away and release the first magnetic plate 403. The first magnetic plate 403 will act on the second magnetic plate 406 to move, and the first magnetic plate 403 is isolated by the partition plate 405. The amount of release will be determined by the bending degree of the bimetallic strip 409, and the bending degree of the bimetallic strip 409 is determined by the time of the high-frequency vibration. In this way, the movement of the second magnetic plate 406 can be adaptively driven effectively according to the time of the high-frequency vibration, thereby making corresponding high-frequency vibration isolation switching.

[0039] Please refer to Figure 3 to Figure 4 The support column 315 is fixedly connected to the mounting tube 2, and an air storage tank 313 is provided inside the support column 315. A first threaded plate 308 is slidably connected inside the air storage tank 313. A second screw 310 is threadedly connected to the first threaded plate 308. The second screw 310 passes through the support column 315 and is rotatably connected to the support column 315.

[0040] When the second magnetic plate 406 moves downward, the second magnetic plate 406 will drive the driving frame 402 to move downward, and the driving frame 402 will rotate the first gear 303 through the latching tooth 410. The rotation of the first gear 303 will drive the worm 304 to rotate through the pulley 306 and the connecting belt 305. The worm 304 drives the worm wheel 301 to rotate. The worm wheel 301 drives the first screw 302 to rotate. The first screw 302 drives the second screw 310 to rotate through the first sprocket 311 and the first chain 312. The second screw 310 drives the first threaded plate 308 to move upward. The first threaded plate 308 moves upward. More high-pressure nitrogen will enter the cylinder 702, so that there will be more high-pressure nitrogen in the cylinder 702. Since the increase of high-pressure nitrogen in the cylinder 702 will increase its natural frequency, this will help to make more high-frequency vibrations fall outside the effective frequency range of vibration isolation, thereby improving the efficiency of high-frequency vibration isolation. In this way, according to the needs of vibration isolation during transportation, high-frequency vibration isolation or low-frequency vibration isolation can be automatically switched, and the upward movement distance of the first threaded plate 308 will increase with the time of high-frequency vibration. In this way, according to the situation of high-frequency vibration, it can be adaptively adjusted to better isolate high-frequency vibration.

[0041] like Figure 11 to Figure 12 As shown, the pressure relief assembly includes a fixed ring 709, a rubber ring 711 is fixedly connected to the outer surface of the fixed ring 709, and a plurality of damping holes 708 are formed on the rubber ring 711; a piston rod 706 is fixedly connected to the inside of the fixed ring 709, the piston rod 706 is fixedly connected to the mounting cover 701, a groove is formed inside the piston rod 706, a third magnetic plate 714 is provided inside the groove, a blocking column 716 is fixedly connected to the third magnetic plate 714, the blocking column 716 extends to the inside of the damping hole 708, a third spring 715 is sleeved on the blocking column 716, and two ends of the third spring 715 are fixedly connected to the third magnetic plate 714 and the piston rod 706 respectively;

[0042] A limiting plate 713 is provided between the two third magnetic plates 714, and the limiting plate 713 is fixedly connected to the piston rod 706. A second spring 712 is provided between the two limiting plates 713, and one end of the second spring 712 is fixedly connected to the piston rod 706, and the other end of the second spring 712 is fixedly connected to a magnetic block 710, and the magnetic block 710 is slidably connected to the groove, and the magnetic block 710 and the third magnetic plate 714 repel each other magnetically; a sliding tube 602 is fixedly connected to the support column 315, and a first air guide tube 601 is fixedly connected to the sliding tube 602, and the first air guide tube 601 is connected to the air storage tank 313, and a second air guide tube 603 is slidably connected inside the sliding tube 602, and the second air guide tube 603 extends to the inside of the mounting cover 701 and is connected to the groove in the piston rod 706.

[0043] It should be noted that, in the process of the first threaded plate 308 moving upward, high-pressure nitrogen will not only be added to the cylinder body 702, but also to the inside of the piston rod 706 through the first air pipe 601 and the second air pipe 603, so that the air pressure inside can be increased, and the magnetic block 710 can be continuously moved downward by means of the air pressure. When the magnetic block 710 moves downward to the specified position, it will act on the third magnetic plate 714, and the third magnetic plate 714 will extend the blocking column 716 to the inside of the damping hole 708, thereby blocking part of the damping hole 708. From the perspective of energy absorption, reducing the damping hole 708 will cause the oil to be subjected to greater viscous resistance when flowing through the rubber ring 711. Under high-frequency vibration, this greater resistance can more effectively convert vibration energy into heat energy, thereby better absorbing high-frequency vibration energy, and thus can be effectively applied to the effect of high-frequency vibration isolation.

[0044] like Figures 5 and 6 , Fig. 9 As shown, a plurality of hollow tubes 502 are rotatably connected to the friction box 408, a second sprocket 506 is fixedly connected to the hollow tube 502, and the plurality of second sprockets 506 are connected via a second chain 503, a second gear 504 is fixedly connected to the hollow tube 502, a rack 505 is meshed on the second gear 504, the rack 505 is slidably connected to the friction plate 404, the rack 505 penetrates the friction box 408 and is slidably connected to the friction box 408, and a hollow heat sink 501 is fixedly connected to the hollow tube 502;

[0045] It should be noted that the gas extracted during the up and down movement of the friction plate 404 will be discharged through the hollow tube 502, and the discharged gas will act on the first spring 703, the piston rod 706, and the cylinder body 702 to cool them down and prevent their temperature from being too high and affecting the vibration isolation effect. In addition, the friction plate 404 will also drive the rack 505 to move during the up and down movement, and the rack 505 will rotate the second gear 504, and the second gear 504 will drive the hollow tube 502 to rotate. The rotation of one hollow tube 502 will drive multiple hollow tubes 502 to rotate through the second sprocket 506 and the second chain 503. The rotation of the hollow tube 502 will drive the hollow heat sink 501 to rotate. The rotation of the hollow heat sink 501 can not only change the trajectory of the ejected gas, but also accelerate the air flow in the mounting tube 2, thereby further achieving a heat dissipation effect.
