DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Example 1: Reference Figure 1-Figure 2, a rollover suspension structure for an amphibious vehicle, comprising a vehicle body 1 for overall support and a plurality of moving wheels 2, wherein the vehicle body 1 is made of aviation high-strength aluminum material as a whole, and has the advantages of light weight, high strength, good corrosion resistance, etc.; 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 , and the two suspension boxes 3 are each provided with two moving wheels 2 for overall movement.

[0024] In a further embodiment, both suspension boxes 3 are provided with a flip suspension structure, and each flip suspension structure is composed of a supporting unit, a lifting unit and a buffer unit; The support unit is arranged in the suspension box 3, and is used to support the moving wheel 2 as a whole and realize the automatic flipping of the moving wheel 2, thereby improving the overall stability of the moving wheel 2, and realizing the flipping and angle adjustment of the moving wheel 2, so that the moving wheel 2 will not cause any obstruction when the vehicle body 1 travels on the water surface; The lifting unit is arranged in the suspension box 3 and is used to adjust the height of the moving wheel 2. It can adapt to the turning of the moving wheel 2 and automatically adjust the height of the moving wheel 2 according to the bumpiness of the road surface on land, thereby improving the overall driving stability of the vehicle body 1. The buffer unit is arranged in the suspension box 3, and is used to realize shock absorption and buffering of the moving wheel 2. The buffer strength is automatically adjusted according to the height position of the moving wheel 2 to realize targeted buffering and shock absorption, and can avoid the situation where the buffering effect is insufficient after the height of the moving wheel 2 is adjusted.

[0025] Example 2: Reference Figure 2-Figure 6 , the technical solution of this embodiment is different from that of the first embodiment in that: the support unit includes a support component and a flip component, wherein the flip component is used to adjust the angle of the moving wheel 2 to achieve automatic flipping; The supporting assembly includes a driving central axis 7, and the driving central axis 7 is connected to the driving system in the vehicle body 1. The driving system is a built-in drive of the vehicle body 1, which is used to transmit power and promote the rotation of the driving central axis 7. The driving system can adapt to the height adjustment of the driving central axis 7 so that the height adjustment of the driving central axis 7 will not affect the transmission of driving power. The specific driving method of the driving system is the existing technology and will not be elaborated here.

[0026] Two sliding sealing plates are slidably mounted on the side of the suspension box 3, and linkage rollers 10 are fixedly mounted on both ends of the driving central shaft 7, and the two linkage rollers 10 both penetrate the corresponding sliding sealing plates, and the two turnover components are both arranged on the two linkage rollers 10; The two sliding sealing plates can be raised or lowered in height as the height of the driving central shaft 7 and the linkage roller 10 is adjusted, and will not affect the normal rotation of the driving central shaft 7 and the linkage roller 10; The two sliding sealing plates play the role of sealing the suspension box 3, which will not affect the rotation of the linkage roller 10, and can also seal the inside of the suspension box 3 to prevent external water from entering the interior of the suspension box 3 during driving.

[0027] In a further embodiment, the flip assembly includes two traction motors 6 fixedly mounted on the suspension box 3, a support frame 5 is fixedly mounted on the linkage roller 10, a deflection shaft 11 is rotatably mounted on the support frame 5, a connecting shaft is fixedly mounted on the deflection shaft 11, and the moving wheel 2 is fixedly arranged at the end of the connecting shaft; When the driving center 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. The rotation of the support frame 5 will drive the deflection shaft 11 to rotate, thereby driving the moving wheel 2 to rotate through the connecting shaft, and then the moving wheel 2 rotates to drive the vehicle body 1 to move as a whole.

[0028] A protective cover is provided 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 travels on the water surface.

[0029] Traction rollers are fixedly installed on the driving ends of the two traction motors 6, and traction ropes are wound inside the traction rollers, and the ends of the traction ropes are fixedly connected to traction hooks 12. When the angle of the moving wheel 2 needs to be adjusted, the traction 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, the traction motor 6 is started to drive the traction roller to rotate. The rotation of the traction roller will reel in the traction rope, so that the connecting shaft is pulled through the cooperation of the traction hook 12 and the traction hanging ring 13 to deflect upward with the deflection axis 11 as the central axis, thereby driving the moving wheel 2 to flip upward as a whole, and the deflection angle of the moving wheel 2 can be flexibly adjusted according to actual use requirements, so that the flipping and angle adjustment of the moving wheel 2 can be realized.

[0030] Example 3: Reference Figure 7-Figure 9 , the technical solution of this embodiment is different from that of the second embodiment in that: the lifting unit includes a liquid pushing component and an adjusting component, wherein the adjusting component realizes the height adjustment of the moving wheel 2 under the drive of the liquid pushing component; The liquid pushing assembly includes a storage box 8 fixedly installed in the suspension box 3, a liquid pushing plate 20 is slidably installed in the storage box 8, and the storage box 8 is filled with hydraulic oil at the upper part of the liquid pushing plate 20, a hydraulic lifting rod 21 is arranged at the bottom of the storage box 8, and the liquid pushing plate 20 is fixedly installed on the driving end of the hydraulic lifting rod 21, and a plurality of supporting springs 22 are fixedly installed between the liquid pushing plate 20 and the bottom wall of the storage box 8; When the overall height of the moving wheel 2 needs to be adjusted, the hydraulic lifting rod 21 can be started to drive the liquid pushing plate 20 to move upward in the storage box 8. When the liquid pushing plate 20 moves upward (the liquid pushing plate 20 moves upward and simultaneously stretches multiple supporting springs 22), the hydraulic oil on the upper part thereof will be squeezed, thereby pushing the hydraulic oil out of the storage box 8.

[0031] In a further embodiment, two adjustment components are arranged in each suspension box 3, and the adjustment components include a lifting adjustment box 9 fixedly arranged in the suspension box 3, and a lifting plate 23 is slidably installed in each lifting adjustment box 9, and a lifting ring 18 is sleeved on the linkage roller 10, and two bent linkage rods 15 for adjusting the height are fixedly installed between the lifting ring 18 and the lifting plate 23, and a liquid guide tube 19 for conducting hydraulic oil is fixedly connected between the storage box 8 and the lifting adjustment box 9, and a control valve 14 is arranged on the liquid guide tube 19; When the push plate 20 moves upward, the control valves 14 in the two liquid guide tubes 19 are opened, so that the hydraulic oil pushed out of the storage box 8 is poured into the liquid guide tubes 19, and then poured into the lifting and adjusting box 9 through the liquid guide tubes 19; When the hydraulic oil in the lifting adjustment box 9 increases, the lifting plate 23 will be pushed upward, and the lifting plate 23 will drive the two bent linkage rods 15 to move upward, thereby pulling the lifting ring 18 to move upward. Since the lifting ring 18 is sleeved on the outside of the linkage roller 10, when the lifting ring 18 moves upward, it will pull the linkage roller 10 to move upward, and when the linkage roller 10 moves upward, it will drive the moving wheel 2 to move upward, thereby completing the automatic adjustment of the height position of the moving wheel 2.

[0032] When the hydraulic lifting rod 21 drives the liquid pushing plate 20 to move downward, the multiple supporting springs 22 will automatically shrink, and at the same time, the gravity of the linkage roller 10 will drive the bending linkage rod 15 and the lifting plate 23 to descend. When the lifting plate 23 descends, the hydraulic oil in the lifting adjustment box 9 will be pressed back to the storage box 8 through the liquid guide tube 19, so that the hydraulic oil recovery and the lowering of the height of the linkage roller 10 can be completed, and the position of the moving wheel 2 can be adjusted downward.

[0033] By utilizing the flow resistance characteristics of hydraulic oil and the incompressibility of liquid, a larger lifting force can be applied so that the moving wheel 2 can be automatically lifted in different environments. In addition, two sets of lifting units can lift the two linked rollers 10 at the same time, which is more efficient. There will be no tilting due to uneven force when adjusting the height.

[0034] Example 4: Reference Figure 7 as well as Figure 10-15 , the technical solution of this embodiment is different from that of the third embodiment in that: the buffer unit includes a linkage support component and a buffer component, wherein the linkage support component is used to realize the height following and stable support of the buffer component, and cooperates with the buffer component to realize the shock absorption and buffering of the moving wheel 2; The linkage support assembly includes a telescopic support rod fixedly mounted on the bottom of the suspension box 3, the telescopic support rod has a certain elasticity, the end of which can automatically pop out and retract, and a buffer box 16 is fixedly mounted on the telescopic support rod; The buffer assembly includes a buffer ring 24 mounted on the linkage roller 10. When the linkage roller 10 moves upward, it will pull the buffer ring 24 mounted thereon to move upward. When the buffer ring 24 moves upward, it will pull the buffer box 16 as a whole 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 with the height of the linkage roller 10, so that the distance between the buffer box 16 and the linkage roller 10 is always maintained within a certain range, thereby ensuring that the buffering and shock-absorbing effect of the buffer box 16 will not be affected by the height of the linkage roller 10.

[0035] A linkage slide 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 the linkage slide rod 26 is opened on the limit support plate 25. When the buffer box 16 is lifted or slid, the linkage slide rod 26 will be driven to slide vertically on the limit support plate 25, thereby ensuring that the buffer box 16 can only slide vertically without position displacement.

[0036] In a further embodiment, a positioning mechanism is installed between the limit support plate 25 and the linkage slide rod 26, and the positioning mechanism includes a hydraulic push rod 30 arranged at the lower part of the linkage slide rod 26, and a positioning card plate 31 is fixedly installed on the driving end of the hydraulic push rod 30, and a plurality of positioning card slots 28 matching with the positioning card plate 31 are opened in the limit support plate 25, and a support card frame 29 is fixedly installed at the lower part of the linkage slide rod 26, and the support card frame 29 is slidably matched with the positioning card plate 31; When 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 supporting card frame 29, and the positioning card plate 31 can be slid and engaged into the corresponding position positioning card slot 28 in the limiting support plate 25, so that the linkage slide rod 26 and the buffer box 16 can be rigidly fixed and supported, so that the buffer box 16 is fixed in position after the height adjustment of the linkage roller 10 is completed, so that the vibration effect generated by the moving wheel 2 during driving will only act on the inside of the buffer box 16, and will not affect the buffer box 16 itself and cause the buffer box 16 to shake.

[0037] Instructions attached Figure 11-12 The number of the positioning slots 28 on the limit support plate 25 shown is only a schematic number and does not represent the actual number of the positioning slots 28. The actual number of the positioning slots 28 can be opened according to actual conditions.

[0038] In a further embodiment, two partition plates 33 are fixedly installed in the buffer box 16, and a squeeze plate 4 is slidably installed between the two partition plates 33, and the squeeze plate 4 is fixedly connected to the lower part of the buffer ring 24, and a damping mechanism is provided in the buffer box 16; The damping mechanism includes two lifting buffer plates 35 slidably mounted on the two partition plates 33 and the side walls of the buffer box 16, and a plurality of damping springs 36 are fixedly mounted between the two lifting buffer plates 35 and the top wall of the buffer box 16. The lower parts of the squeeze plate 4 and the two lifting buffer plates 35 in the buffer box 16 are filled with hydraulic oil, and a plurality of liquid-passing conduits 34 for guiding liquid are fixedly connected to the two partition plates 33. When the moving wheel 2 vibrates during travel, the vibration will be transmitted to the linkage roller 10 and then to the buffer ring 24. The vibration of the buffer ring 24 will drive the squeeze plate 4 to move up and down between the two partition plates 33.

[0039] For the convenience of explanation, the area between the two partition plates 33 and the squeezing plate 4 in the buffer box 16 is named as the middle area, and the side parts of the two partition plates 33 and the lower area of ​​the lifting buffer plate 35 are named as the side area, and the same applies to the above descriptions. When the squeezing plate 4 moves downward, it squeezes the hydraulic oil in the lower middle area thereof and transmits it to the two side areas through multiple liquid-passing ducts 34. The increase of hydraulic oil in the two side areas will push the lifting buffer plate 35 to move upward. The upward movement of the lifting buffer plate 35 will compress multiple shock-absorbing springs 36. The shock-absorbing springs 36 will rebound after compression, thereby pushing the lifting buffer plate 35 down, and then pressurizing the hydraulic oil in the side areas back to the middle area through multiple liquid-passing ducts 34. In this process, the reciprocating flow of the hydraulic oil and the compression and rebound of the shock-absorbing springs 36 are used to consume the vibration potential energy. At the same time, the hydraulic oil has a larger flow resistance and consumes more energy when flowing, so the absorption effect of the vibration potential energy is better, thereby achieving a better buffering and shock-absorbing effect.

[0040] The storage box 8 is fixedly connected with a liquid replenishing pipe 17 for replenishing liquid, and a control valve 14 is arranged on the liquid replenishing pipe 17. Two connecting pipes 32 are fixedly connected between the liquid replenishing pipe 17 and the buffer box 16, and the liquid outlet ends of the two connecting pipes 32 are respectively located on both sides of the two partition plates 33; The buffering strength can be adjusted according to the bumps of the road surface. In the initial state, the hydraulic oil in the storage box 8 is injected into the two side areas of the buffer box 16 through the infusion pipe 17 and the two connecting pipes 32 by starting the push assembly, thereby pushing the two lifting buffer plates 35 in the side areas to move upward, thereby compressing multiple shock-absorbing springs 36. The compression degree of the shock-absorbing springs 36 can be adjusted in the initial state, so as to adjust the energy consumption and the compression-stretching rebound amount of the shock-absorbing springs 36 (the lower the compression degree, the greater the energy consumption and the better the buffering effect), thereby playing a role in adjusting the buffering strength, so that the overall buffering effect of the buffer box 16 is better.

[0041] The working principle of this flip suspension structure is: When the overall height of the moving wheel 2 needs to be adjusted, the hydraulic jacking rod 21 is started to drive the liquid pushing plate 20 to move upward, so that the hydraulic oil pushed out of the storage box 8 is poured into the liquid guide tube 19, and then poured into the lifting adjustment box 9 through the liquid guide tube 19. The increase of hydraulic oil in the lifting adjustment box 9 will push the lifting plate 23 to move upward, and the lifting plate 23 will move upward, which will drive the two bent linkage rods 15 and the lifting ring 18 to move upward. The lifting ring 18 moves upward and 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. When the angle of the moving wheel 2 needs to be adjusted, the traction rope can be pulled out and the traction hook 12 can be hung in the traction ring 13 on the connecting shaft. At this time, the traction motor 6 is started to drive the traction roller to rotate. The rotation of the traction roller will reel in the traction rope, so that through the cooperation of the traction hook 12 and the traction ring 13, the connecting shaft is pulled to deflect upward with the deflection axis 11 as the central axis, thereby driving the moving wheel 2 to flip upward as a whole. The deflection angle of the moving wheel 2 can be flexibly adjusted according to actual use requirements, and the flipping and angle adjustment of the moving wheel 2 can be realized.

[0042] The buffer strength is adjusted according to the bumps of the road surface. In the initial state, the hydraulic oil in the storage box 8 is injected into the two side areas of the buffer box 16 through the infusion pipe 17 and the two connecting pipes 32 by starting the push assembly, thereby pushing the two lifting buffer plates 35 in the side areas to move upward, thereby compressing multiple shock-absorbing springs 36. The compression degree of the shock-absorbing springs 36 can be adjusted in the initial state, so as to adjust the energy consumption and compression-stretching rebound amount of the shock-absorbing springs 36, thereby playing a role in adjusting the overall buffer strength.

[0043] The embodiment of the present invention further provides a method for using a rollover suspension structure for an amphibious vehicle, which is used for the rollover suspension structure of the amphibious vehicle, and comprises the following steps: S1, the plurality of moving wheels 2 rotate under the drive of the driving system in the vehicle body 1, so as to realize the movement of the vehicle body 1 on the road; S2.
