Description

Technical Field

[0001] The present invention relates to the technical field of amphibious vehicles, and in particular to a flip suspension structure for an amphibious vehicle and a method for using the same. Background Art

[0002] An amphibious vehicle, also known as an amphibious boat, is a special equipment that combines the dual performance of a vehicle and a boat. It can not only travel on land but also float on water, with strong mobility and can adapt to various complex terrains and waters. A flip suspension structure is usually provided on the wheels of an amphibious vehicle to facilitate adaptation to road surfaces in different environments and achieve automatic flipping of the wheels on water.

[0003] There are various forms of the existing flip suspension structures for amphibious vehicles. For example, a wheel retracting adjustable suspension structure for an amphibious vehicle with the publication number of CN116811505A includes an axle; a wheel retracting mechanism, which includes a suspension assembly, a wheel retracting assembly, a telescopic assembly, and a rotation limiting assembly; among them, the wheel retracting assembly includes a driving oil cylinder, the lower end of the driving oil cylinder is fixedly connected to the axle, and the upper end of the driving oil cylinder is hinged with a three-way joint.

[0004] The existing flip suspension structures usually adjust the wheels by means of height lifting and flipping, without regulating the running shock absorption effect of the wheels. The shock absorption system in the suspension structure cannot be adaptively adjusted according to the height of the wheels, resulting in a worse shock absorption effect when the wheel height is higher. For example, in the above-mentioned existing technology for reference, the device only uses a driving oil cylinder and the first telescopic link and the second telescopic link to lift the wheels, and the driving oil cylinder, the first telescopic link, and the second telescopic link are all rigidly connected, with poor shock absorption effect and unable to be adjusted by itself. At the same time, the shock absorber used in this device cannot achieve the adaptability of the shock absorption effect of the wheels under complex road surfaces, and the overall support shock absorption effect is poor.

[0005] Therefore, it is urgent to design a flip suspension structure for an amphibious vehicle and a method for using the same to solve the above problems. Summary of the Invention

[0028] 2. When the flipping suspension structure is actually used, through the cooperation of the liquid-pushing component, the automatic adjustment of the height of the moving wheels can be realized. By using the flow resistance characteristics of hydraulic oil, a large lifting force can be applied, so that the moving wheels can be automatically lifted in different environments, with high lifting efficiency and strong stability.

[0029] 3. When the flipping suspension structure is actually used, it can automatically adjust the height of the moving wheels according to the bumpy situation of the road surface, and can adjust the height of the buffer unit along with the height adjustment of the moving wheels, avoiding the problem of reduced buffering effect due to different heights, with better buffering effect and stronger driving stability.

Specific implementation mode

[0050] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0051] Embodiment 1: Refer to Figure 1 - Figure 2 , a flipping suspension structure for an amphibious vehicle, including a vehicle body 1 for overall support and a plurality of moving wheels 2. The vehicle body 1 is made of aviation high-strength aluminum material as a whole, having the advantages of light weight, high strength, and good corrosion resistance;

[0052] Two suspension boxes 3 are fixedly arranged in the vehicle body 1, and the two suspension boxes 3 are respectively located at the front and rear parts of the vehicle body 1. Two moving wheels 2 for overall movement are arranged on both suspension boxes 3.

[0053] In a further embodiment, a flipping suspension structure is arranged in each of the two suspension boxes 3, and each flipping suspension structure is composed of a support unit, a lifting unit and a buffer unit;

[0054] The support unit is arranged in the suspension box 3, and is used for overall support of the moving wheel 2 and realizing the automatic flipping of the moving wheel 2, improving the overall stability of the moving wheel 2, and at the same time realizing the flipping and angle adjustment of the moving wheel 2, so that when the vehicle body 1 travels on the water surface, the moving wheel 2 will not cause obstruction;

[0055] The lifting unit is arranged in the suspension box 3, and is used for realizing the height adjustment of the moving wheel 2, which can not only adapt to the flipping of the moving wheel 2, but also automatically adjust the height of the moving wheel 2 according to the bumpiness of the road surface on land, improving the overall driving stability of the vehicle body 1;

[0056] The buffer unit is arranged in the suspension box 3, and is used for realizing the shock absorption and buffering of the moving wheel 2, automatically adjusting the buffer strength according to the height position of the moving wheel 2, realizing targeted shock absorption and buffering, and can avoid the situation of insufficient buffer effect after the height adjustment of the moving wheel 2.

[0057] Embodiment 2: Referring to Figure 2 - Figure 6 , the different technical solution of this embodiment compared with Embodiment 1 is that the support unit includes a support component and a flipping component, wherein the flipping component is used to adjust the angle of the moving wheel 2 to achieve automatic flipping;

[0058] The support component includes a driving central shaft 7, and the driving central shaft 7 is connected to the driving system in the vehicle body 1. The driving system is an in-built drive of the vehicle body 1, which is used to transmit power and promote the rotation of the driving central shaft 7. The driving system can adapt to the height adjustment of the driving central shaft 7 so that the height adjustment of the driving central shaft 7 will not affect the transmission of driving power. The specific driving method of the driving system is the prior art and will not be elaborated here.

[0059] Two sliding sealing plates are slidably installed on the side of the suspension box 3, and linkage rollers 10 are fixedly installed at both ends of the driving central shaft 7. Both linkage rollers 10 penetrate through the corresponding sliding sealing plates, and both flipping components are arranged on the two linkage rollers 10;

[0060] The two sliding sealing plates can be lifted and lowered with the height adjustment of the driving central shaft 7 and the linkage rollers 10, and will not affect the normal rotation of the driving central shaft 7 and the linkage rollers 10;

[0061] The two sliding sealing plates play a role in sealing the suspension box 3, which will neither affect the rotation of the linkage rollers 10 nor internally seal the suspension box 3 to prevent external water from entering the interior of the suspension box 3 during driving.

[0062] In a further embodiment, the flipping component includes two traction motors 6 fixedly installed on the suspension box 3. A support frame 5 is fixedly installed on the linkage roller 10, and a deflecting shaft 11 is rotatably installed on the support frame 5. A connecting shaft is fixedly installed on the deflecting shaft 11, and the moving wheel 2 is fixedly arranged at the end of the connecting shaft;

[0063] When the driving central shaft 7 rotates, it will drive the linkage roller 10 to rotate. When the linkage roller 10 rotates, it will drive the support frame 5 to rotate. When the support frame 5 rotates, it will drive the deflecting shaft 11 to rotate, thereby driving the moving wheel 2 to rotate through the connecting shaft, and further realizing the rotation of the moving wheel 2 to drive the whole vehicle body 1 to move.

[0064] A protective cover is arranged on the suspension box 3, and the traction motor 6 is located inside the protective cover. The protective cover plays a role in protecting the traction motor 6 to prevent water on the water surface from entering the traction motor 6 when the vehicle body 1 is driving on the water surface.

[0065] On the driving ends of both traction motors 6, traction rollers are fixedly installed, and a traction rope is wound inside the traction rollers. The end of the traction rope is fixedly connected to a traction hook 12. When it is necessary to adjust the angle of the moving wheel 2, the traction rope can be pulled out and the traction hook 12 can be hung into the traction loop 13 on the connecting shaft. At this time, the traction motor 6 is started to drive the traction roller to rotate. When the traction roller rotates, it will wind up the traction rope. Thus, through the cooperation of the traction hook 12 and the traction loop 13, the connecting shaft is pulled to deflect upward with the deflection shaft 11 as the center axis, thereby driving the entire moving wheel 2 to flip upward. The deflection angle of the moving wheel 2 can be flexibly adjusted according to actual use requirements, realizing the free adjustment of the flip and angle of the moving wheel 2.

[0066] Embodiment 3: Refer to Figure 7 - Figure 9 , the different technical solution of this embodiment compared with Embodiment 2 is that: the lifting unit includes a liquid pushing component and an adjusting component, and the adjusting component realizes the height adjustment of the moving wheel 2 under the drive of the liquid pushing component;

[0067] The liquid pushing component includes a storage tank 8 fixedly installed in the suspension box 3. A liquid pushing plate 20 is slidably installed in the storage tank 8, and hydraulic oil is filled in the upper part of the storage tank 8 where the liquid pushing plate 20 is located. A hydraulic lifting rod 21 is arranged at the bottom of the storage tank 8, and the liquid pushing plate 20 is fixedly installed on the driving end of the hydraulic lifting rod 21. A plurality of support springs 22 are fixedly installed between the liquid pushing plate 20 and the bottom wall of the storage tank 8;

[0068] When it is necessary to adjust the overall height of the moving wheel 2, the hydraulic lifting rod 21 can be started to drive the liquid pushing plate 20 to move upward in the storage tank 8. When the liquid pushing plate 20 moves upward (while the liquid pushing plate 20 moves upward and stretches a plurality of support springs 22), it will squeeze the hydraulic oil above it, thereby pushing the hydraulic oil out of the storage tank 8.

[0069] In a further embodiment, two adjusting components are arranged in each suspension box 3. The adjusting component includes a lifting adjusting box 9 fixedly arranged in the suspension box 3. A lifting plate 23 is slidably installed in each lifting adjusting box 9. A lifting ring 18 is sleeved on the linkage roller 10, and two bending linkage rods 15 for adjusting the height are fixedly installed between the lifting ring 18 and the lifting plate 23. A liquid guiding pipe 19 for conducting hydraulic oil is fixedly connected between the storage tank 8 and the lifting adjusting box 9, and a control valve 14 is arranged on the liquid guiding pipe 19;

[0070] While the liquid pushing plate 20 moves upward, the control valves 14 in the two liquid guiding pipes 19 are opened, so that the hydraulic oil pushed out of the storage tank 8 is poured into the liquid guiding pipe 19 and then poured into the lifting adjusting box 9 through the liquid guiding pipe 19;

[0071] When the hydraulic oil in the lifting adjustment box 9 increases, it will push the lifting plate 23 upward. When the lifting plate 23 moves upward, it will drive the two bent linkage rods 15 upward, thereby pulling the lifting ring 18 upward. Since the lifting ring 18 is sleeved outside the linkage roller 10, when the lifting ring 18 moves upward, it will pull the linkage roller 10 upward. When the linkage roller 10 moves upward, it will drive the moving wheel 2 upward, and the automatic adjustment of the height position of the moving wheel 2 can be completed.

[0072] When the hydraulic jacking rod 21 drives the liquid pushing plate 20 downward, at this time, the multiple support springs 22 will automatically contract, and at the same time, the gravity of the linkage roller 10 is used to drive the bent linkage rod 15 and the lifting plate 23 to descend. When the lifting plate 23 descends, it will press the hydraulic oil in the lifting adjustment box 9 back into the storage box 8 through the liquid guide pipe 19, and the recovery of the hydraulic oil and the descent of the height of the linkage roller 10 can be completed, realizing the downward adjustment of the position of the moving wheel 2.

[0073] By utilizing the flow resistance characteristics of the hydraulic oil and the incompressibility of the liquid, a relatively large lifting force can be applied, enabling the moving wheel 2 to be automatically lifted in different environments, and the two sets of lifting units simultaneously lifting the two linkage rollers 10 has higher efficiency, and there will be no situation of uneven force and tilting during height adjustment.

[0074] Example 4: Refer to Figure 7 and Figure 10 - Figure 15 , the different technical solutions of this embodiment compared with Embodiment 3 are: The buffer unit includes a linkage support component and a buffer component, wherein the linkage support component is used to realize the height follow-up and stable support of the buffer component, and cooperate with the buffer component to realize the shock absorption and buffering of the moving wheel 2;

[0075] The linkage support component includes a telescopic support rod fixedly installed at the bottom of the suspension box 3. The telescopic support rod has a certain elasticity, its end can automatically pop out and stretch, and a buffer box 16 is fixedly installed on the telescopic support rod;

[0076] The buffer component includes a buffer sleeve ring 24 sleeved on the linkage roller 10. When the linkage roller 10 moves upward, it will pull the buffer sleeve ring 24 sleeved on it upward. When the buffer sleeve ring 24 moves upward, it will pull the whole buffer box 16 upward under the action of the internal negative pressure of the buffer box 16 and the cooperation of the telescopic support rod, thereby completing the automatic adjustment of the height of the buffer box 16 following the height of the linkage roller 10, so that the distance between the buffer box 16 and the linkage roller 10 always remains within a certain range, and further ensuring that the shock absorption and buffering effect of the buffer box 16 will not be affected by the height of the linkage roller 10.

[0077] A linkage sliding rod 26 is fixedly installed on the side of the buffer box 16. A limit support plate 25 is fixedly installed in the suspension box 3, and a sliding groove 27 matching with the linkage sliding rod 26 is formed on the limit support plate 25. When the buffer box 16 moves up and down and slides, it will drive the linkage sliding rod 26 to slide vertically on the limit support plate 25, so as to ensure that the buffer box 16 can only slide vertically and will not be displaced.

[0078] In a further embodiment, a positioning mechanism is installed between the limit support plate 25 and the linkage sliding rod 26. The positioning mechanism includes a hydraulic push rod 30 arranged at the lower part of the linkage sliding rod 26, and a positioning card plate 31 is fixedly installed on the driving end of the hydraulic push rod 30. A plurality of positioning card slots 28 matching with the positioning card plate 31 are formed in the limit support plate 25. A support card frame 29 is fixedly installed at the lower part of the linkage sliding rod 26, and the support card frame 29 is slidably matched with the positioning card plate 31;

[0079] After the height position of the buffer box 16 is adjusted, the hydraulic push rod 30 can be started to drive the positioning card plate 31 to slide on the support card frame 29, and the positioning card plate 31 is slidably engaged into the corresponding positioning card slot 28 in the limit support plate 25, so as to complete the rigid fixation and support of the linkage sliding rod 26 and the buffer box 16. Thus, after the height of the linkage roller 10 is adjusted, the position of the buffer box 16 is fixed, so that the vibration effect generated during the running of the moving wheel 2 only acts on the inside of the buffer box 16 and will not affect the buffer box 16 itself to cause the buffer box 16 to shake.

[0080] Instruction manual appendix Figure 11 - 12 The number of the positioning card slots 28 shown on the limit support plate 25 is only a schematic number and does not represent the actual number of the positioning card slots 28. The actual number of the positioning card slots 28 can be opened according to the actual situation.

[0081] In a further embodiment, two partition plates 33 are fixedly installed in the buffer box 16, and a liquid extrusion plate 4 is slidably installed between the two partition plates 33. The liquid extrusion plate 4 is fixedly connected with the lower part of the buffer sleeve ring 24, and a damping mechanism is arranged in the buffer box 16;

[0082] The damping mechanism includes two lifting buffer plates 35 slidably installed between the two partition plates 33 and the side wall of the buffer box 16. A plurality of shock absorption springs 36 are fixedly installed between the two lifting buffer plates 35 and the top wall of the buffer box 16. Hydraulic oil is filled in the buffer box 16 below the liquid extrusion plate 4 and the two lifting buffer plates 35, and a plurality of liquid guiding conduits 34 for guiding liquid are fixedly communicated with the two partition plates 33;

[0083] When the moving wheel 2 generates vibrations during driving, the vibration effect will be transmitted into the linkage roller 10 and then into the buffer collar 24. Once the buffer collar 24 generates vibrations, it will act on the liquid extrusion plate 4, driving the liquid extrusion plate 4 to move up and down between the two partition plates 33.

[0084] For the convenience of description, the area within the buffer tank 16 between the two partition plates 33 and the liquid extrusion plate 4 is named the middle position area herein, and the lower area of the side parts of the two partition plates 33 and the lifting buffer plate 35 is named the side part area. The same applies to the following descriptions.

[0085] When the liquid extrusion plate 4 moves downward, it will squeeze the hydraulic oil in the middle position area below it, causing the hydraulic oil to be conducted through multiple liquid passing conduits 34 to the two side part areas. The increase in hydraulic oil in the two side part areas will push the lifting buffer plate 35 upward. When the lifting buffer plate 35 moves upward, it will compress multiple shock absorption springs 36. After the shock absorption springs 36 are compressed, they will rebound, pushing the lifting buffer plate 35 downward, and then pressing the hydraulic oil in the side part areas back to the middle position area through the multiple liquid passing conduits 34. During this process, the reciprocating flow of the hydraulic oil and the compression and rebound of the shock absorption springs 36 are used to consume the vibration potential energy. At the same time, the flow resistance of the hydraulic oil is relatively large and it consumes more energy during flow, resulting in a better absorption effect on the vibration potential energy, thus achieving a better buffering and shock absorption effect.

[0086] A liquid supplement pipe 17 for liquid supplement is fixedly connected to the storage tank 8, and a control valve 14 is provided on the liquid supplement pipe 17. Two connecting pipes 32 are fixedly connected between the liquid supplement pipe 17 and the buffer tank 16, and the liquid outlet ends of the two connecting pipes 32 are respectively located on both sides of the two partition plates 33.

[0087] The buffer intensity can be adjusted according to the bumpiness of the driving road surface. In the initial state, by starting the pushing component, the hydraulic oil in the storage tank 8 is respectively poured into the two side part areas in the buffer tank 16 through the liquid supplement pipe 17 and the two connecting pipes 32, thereby pushing the two lifting buffer plates 35 in the side part areas upward, and then compressing multiple shock absorption springs 36. Thus, the compression degree of the shock absorption springs 36 can be adjusted in the initial state, so as to adjust the energy consumption and the compression, stretching and rebound amount of the shock absorption springs 36 (the lower the compression degree, the greater the energy consumption and the better the buffer effect), thereby playing a role in adjusting the buffer intensity and making the overall buffer effect of the buffer tank 16 better.

[0088] The working principle of this flip suspension structure is as follows:

[0089] When it is necessary to adjust the overall height of the moving wheel 2, start the hydraulic jacking rod 21 to drive the liquid pushing plate 20 to move upward, so that the hydraulic oil pushed out of the storage tank 8 is poured into the liquid guide pipe 19, and through the liquid guide pipe 19, it is poured into the lifting adjustment box 9. The increase in the hydraulic oil in the lifting adjustment box 9 will push the lifting plate 23 to move upward. When the lifting plate 23 moves upward, it will drive the two bent linkage rods 15 and the lifting ring 18 to move upward. The upward movement of the lifting ring 18 pulls the linkage roller 10 to move upward. When the linkage roller 10 moves upward, it drives the moving wheel 2 to move upward, and the automatic adjustment of the height position of the moving wheel 2 can be completed;

[0090] When it is necessary to adjust the angle of the moving wheel 2, the traction pull rope can be pulled out and the traction hook 12 can be hung in the traction hanging ring 13 on the connecting shaft. At this time, start the traction motor 6 to drive the traction roller to rotate. When the traction roller rotates, it will wind up the traction pull rope.
