Description

Technical Field

[0001] The invention relates to the technical field of transmission parts for amphibious vehicles, in particular to a transmission system capable of quickly converting from water to land. Background Art

[0002] An amphibious boat is a special equipment that combines the dual performance of a car and a ship. It can travel on land and float on the water. This vehicle has a wide range of applications in professional fields such as transportation, military, disaster relief, and detection due to its excellent water and land performance. Whether it is rugged mountains, vast deserts or turbulent rivers, amphibious boats can demonstrate excellent maneuverability to ensure that tasks are completed in various complex environments. The application fields of amphibious boats are very wide, mainly including: military, disaster relief, environmental detection, and scientific research. When performing search and rescue missions for disaster relief, environmental conditions are often unpredictable, and the vehicle needs to quickly switch to another mode to approach the trapped people. At present, when switching, a clutch is usually used to connect or disconnect the engine from different drive systems, which causes greater wear on the clutch, and the degree of wear on the clutch is not easy to detect. If the clutch fails during the search and rescue mission for disaster relief, not only will the trapped people not be rescued immediately, but it will also bring danger to the search and rescue personnel themselves;

[0003] For example, the transmission system of an amphibious vehicle disclosed in the publication number CN212353503U reduces the space occupied by the power system, but the clutch is used to connect or disconnect the engine and different drive systems, which causes great wear on the clutch, and the degree of wear of the clutch is difficult to detect. The transmission system of a high-speed four-wheel drive amphibious vehicle disclosed in the publication number CN203637488U also has the problem that the clutch is used to connect or disconnect the engine and different drive systems, which causes great wear on the clutch, and the degree of wear of the clutch is difficult to detect.

[0054] (2) The transmission system capable of rapid conversion from water to land provides support force to the corresponding reinforcing rod through the transmission rod one or the transmission rod two, the reinforcing rod provides support force to the magnet, the magnet and the magnetic ring are magnetically attracted to each other, the fixed rod provides support force to the magnetic ring, the electric push rod provides support force to the fixed rod, and the guide sleeve provides support force to the electric push rod; the impact and vibration that may be generated during sudden switching are reduced, the adjustment of the power path is accelerated, and the switching process is ensured to be both fast and smooth, while helping to reduce the noise level of the entire transmission system.

[0086] The conversion assembly also includes: an extrusion plate 3, a second guide rod 31, a second spring 32, an air bag 33, an air pipe 34, a stopper 35, a third guide rod 36, and a third spring 37;

[0087] The outer wall of the extrusion plate 3 is slidably mounted in the switching rod 28 to assist in switching the power mode of the amphibious boat;

[0095] When in use, when the amphibious boat is traveling alone on land or in water, the driving rod 1 11 or the driving rod 2 12 is driven alone to drive the amphibious boat to move;

[0096] When the amphibious boat is in the process of entering water from land or moving from water to land, the transmission part is switched from the transmission rod 11 to the transmission rod 2 12 or from the transmission rod 2 12 to the transmission rod 1 11 by controlling the conversion assembly to start;

[0097] During the transmission state switching process, the following state is always maintained: the transmission gear 14 drives the transmission shaft 101 to rotate, so that the transmission shaft 101 is always in a rotating state, the transmission shaft 101 drives the sliding sleeve 26 to rotate synchronously, the sliding sleeve 26 drives the limit rod 23 to rotate, the limit rod 23 drives the guide rod 24 to rotate, and the guide rod 24 and the support ring 27 are slidably adapted to each other, so that the guide rod 24 can make a circular motion along the support ring 27 under the drive of the limit rod 23, and the sliding rod 22 is driven to rotate by the limit rod 23;

[0098] By driving the sliding rod 22 to slide to the side away from the sliding sleeve 26, the sliding rod 22 drives the limiting rod 23 to move, and the limiting rod 23 and the sliding sleeve 26 slide together so that the limiting rod 23 can only move linearly along the sliding sleeve 26, so that the sliding rod 22 can slide to the side away from the sliding sleeve 26 while rotating with the transmission rod 11 as the axis. When the sliding rod 22 is extended a long enough distance, the sliding rod 22 will slide into the switching rod 28 along the opening of the switching rod 28, so that the sliding rod 22 squeezes the extrusion plate 3 to move, and the extrusion plate 3 and the guide rod 2 31 slide together, and the switching rod 28 gives the guide The second rod 31 provides a supporting force, so that the extrusion plate 3 can only move linearly along the second guide rod 31 under the extrusion of the sliding rod 22, and the extrusion plate 3 squeezes one of the airbags 33, so that the air in the airbag 33 is transported to the airbag on the other side through the trachea 34, and the expansion of the airbag on the other side squeezes the stopper 35 to move, and the stopper 35 and the third guide rod 36 are slidably matched, so that the stopper 35 can only move linearly along the third guide rod 36 under the action of the airbag, so that the stopper 35 extends from the inside of the switching rod 28 to the opening, so that the switching rod 28 and the stopper 35 cooperate with each other to limit the sliding rod 22 in the narrow space between the two;

[0099] At this time, when the transmission gear 14 drives the transmission shaft 101 to rotate, the transmission shaft 101 drives the limit rod 23 to rotate through the sliding sleeve 26, the limit rod 23 drives the switching rod 28 to rotate through the sliding rod 22, and the switching rod 28 drives the transmission rod 1 11 or the transmission rod 2 12 to rotate, thereby completing the transmission switching;

[0100] When switching from the current transmission mode to another transmission mode, the sliding rod 22 currently in the transmission state is controlled to slide toward the side close to the sliding sleeve 26, so that the sliding rod 22 slides directly out of the switching rod 28. At this time, the former power can be stopped, and the switched power unit drives the transmission rod 1 11 or the transmission rod 2 12 to rotate to provide power to the amphibious boat. After the sliding rod 22 that no longer provides power to the amphibious boat slides out of the switching rod 28, the air bag 33 no longer provides an extrusion force to the group of blocks 35, but the spring three 37 provides an elastic force to the block 35, so that the block 35 can be retracted into the switching rod 28 under the action of the spring three 37, and the block 35 retracted in the switching rod 28 squeezes the air bag 33 in turn, so that the capsule body on one side of the extrusion plate 3 expands, and at the same time, the spring two 32 provides an elastic force to the extrusion plate 3, squeezing the extrusion plate 3 to the side where the block 35 is located to reset it, waiting for the next switch to be used;

[0101] When switching, when the sliding rod 22 is just at the same horizontal line with the switching rod 28, the push block 25 at one end of the sliding rod 22 abuts against the sliding block 29, so that the push block 25 squeezes the sliding block 29 to move, so that the sliding rod 22 and the push block 25 squeeze the sliding block 29 to rotate sideways, so that the sliding block 29 drives the switching rod 28 to move synchronously, and the switching rod 28 drives the transmission rod 1 11 or the transmission rod 2 12 to move, so that the sliding rod 22 and the switching rod 28 can be staggered, until the sliding rod 22 can be stuck in the switching rod 28 from the opening;

[0102] The moving rod 210 provides support force to the sliding block 29, and the moving rod 210 and the switching rod 28 are slidably matched, so that the moving rod 210 can drive the sliding block 29 to move linearly along the switching rod 28 under the action of external force, so that when one end of the sliding rod 22 reaches the switching rod 28 at a high speed, it can be smoothly inserted into the switching rod 28 from the opening;

[0103] After the sliding rod 22 is moved out of the switching rod 28, the sliding block 29 is no longer subjected to the force exerted by the sliding rod 22, and the spring 1 211 provides elastic force to the moving rod 210, and the moving rod 210 drives the sliding block 29 to move downward, thereby resetting to the initial state and waiting for the next switching.

[0104] If the sliding rod 22 is not on the same horizontal line as the switching rod 28 during switching, the sliding rod 22 directly slides into the switching rod 28 from the opening, thereby forcing the extrusion plate 3 and the sliding block 29 to move synchronously.

[0105] Embodiment 2, the technical solution of this embodiment is different from that of embodiment 1, including: an auxiliary component for assisting the conversion component to quickly and smoothly convert is arranged in the transfer case 1, and the auxiliary component includes: a reinforcing rod 38, a magnet 39, a magnetic ring 310, a fixing rod 311, an electric push rod 312, a guide sleeve 313, and a displacement sensor 4;

[0106] One end of the reinforcing rod 38 is fixedly mounted on the transmission rod 11 to assist the conversion assembly in rapid and smooth conversion;

[0107] The outer wall of the magnet 39 is fixed to the side wall of the reinforcing rod 38 to apply resistance to the reinforcing rod 38;

[0108] The magnetic ring 310 is sleeved outside the transmission rod 11, and the side wall of the magnetic ring 310 is magnetically connected to the magnet 39. The magnetic ring 310 is used to apply resistance to the reinforcing rod 38;

[0109] One end of the fixing rod 311 is fixed on the side wall of the magnetic ring 310 to provide support for the magnetic ring 310;

[0110] One end of the electric push rod 312 is fixedly mounted on the side wall of the fixed rod 311 to provide power to the fixed rod 311;

[0111] The bottom of the guide sleeve 313 is fixedly installed in the transfer case 1 to provide support for the electric push rod 312, and the outer wall of the fixed rod 311 is slidably inserted into the guide sleeve 313, and the guide sleeve 313 supports and guides the fixed rod 311;

[0112] The bottom of the displacement sensor 4 is fixedly installed in the transfer case 1 to determine the start timing of the auxiliary component.

[0113] When in use, the transmission rod 1 11 or the transmission rod 2 12 provides support force to the corresponding reinforcing rod 38, the reinforcing rod 38 provides support force to the magnet 39, the magnet 39 and the magnetic ring 310 are magnetically attracted to each other, the fixing rod 311 provides support force to the magnetic ring 310, the electric push rod 312 provides support force to the fixing rod 311, and the guide sleeve 313 provides support force to the electric push rod 312;

[0114] During the conversion of the transmission system, the magnet 39 and the magnetic ring 310 are first kept in a magnetically attracted state. When the sliding rod 22 moves toward the opening of the switching rod 28 and squeezes the extrusion plate 3, a certain resistance is applied to the transmission rod 1 11 or the transmission rod 2 12 by the magnetic attraction between the magnet 39 and the magnetic ring 310, so that the transmission rod 1 11 or the transmission rod 2 12 that has not rotated will not shake greatly when the sliding rod 22 just contacts the switching rod 28 or the sliding block 29, so that the sliding rod 22 cannot be smoothly inserted into the switching rod 28, thereby improving the smoothness of the switching of the sliding rod 22;

[0115] After the conversion is completed, the sliding rod 22 is inserted into the opening of the switching rod 28 and extends a short distance from the switching rod 28. Figure 6In the state shown, when the sliding rod 22 rotates to the top of the displacement sensor 4, the value detected by the displacement sensor 4 will be converted from the fixed value A to the fixed value B. The distance of the fixed value A is the distance between the displacement sensor 4 and the transmission rod 1 11 or the transmission rod 2 12. The fixed value B is the distance between the displacement sensor 4 and the sliding rod 22 when the sliding rod 22 rotates to the top of the displacement sensor 4. At this time, the electric push rod 312 is started, and the fixed rod 311 is driven to move by the electric push rod 312. The fixed rod 311 and the guide sleeve 313 are slidably adapted to each other. The fixed rod 311 drives the magnetic ring 310 to move, so that the magnetic ring 310 is separated from the magnet 39, thereby no longer applying a certain resistance to the transmission rod 11 and the transmission rod 2 12.

[0116] Embodiment 3, the technical solution of this embodiment is different from that of embodiment 2 in that: the conversion assembly further includes: a connecting rod 5, a support rod 51, a spring 4 52, a guide block 53, a driven plate 54, a power plate 55, a positioning rod 56, a threaded rod 57, and a fixing block 58;

[0117] One end of the connecting rod 5 is fixedly mounted on the side wall of the support ring 27 to transmit the power required for the movement of the support ring 27;

[0118] The top of the support rod 51 is fixedly mounted on the bottom of the connecting rod 5 to guide and limit the connecting rod 5;

[0119] One end of the spring 4 52 is fixedly mounted on the side wall of the support rod 51, and the other end of the spring 4 52 is fixedly mounted on the inner wall of the guide block 53. The spring 4 52 is used to provide elastic force for the support rod 51 to reset.
