[0024] The application is described below Figures 1-6 A land, water and mud multi-modal amphibious rescue boat is described.

[0025] As Figures 1-2 shown, in one embodiment, a land, water and mud multi-modal amphibious rescue boat, comprising a hull 1 and a main frame 2 fixedly installed on both sides of the hull 1, further comprising: a servo cylinder 3, axially symmetrically installed at both ends of the same side main frame 2; amphibious wheels 4, arranged on both sides of the hull 1, with two on each side; a bracket 5, sleeved on both ends of the amphibious wheel 4; a four-bar linkage floating wheel frame 6, driven by the servo cylinder 3, for adjusting the height of the amphibious wheel 4; a telescopic rod 7, movably installed inside the servo cylinder 3, one end of which is in transmission connection with the four-bar linkage floating wheel frame 6.

[0026] Specifically, the amphibious wheels 4 are arranged at both ends of the hull 1, two on each side, a total of four, which provide power for the overall movement of the hull 1 through rotation of the amphibious wheels 4. The hull 1 is made of a material with high hardness and light texture. High hardness can have good wear resistance, and light texture can make the hull 1 have good buoyancy, which is convenient for driving on water. During driving, the telescopic rod 7 is moved by the servo cylinder 3 to adjust the height of the four-bar linkage floating wheel frame 6 to the bracket 5 and the amphibious wheel 4. When driving on water, the amphibious wheels 4 are lifted upwards, which can significantly reduce the "form drag" caused by the volume of the vehicle body and wheels immersed in water, thereby improving the running speed on water. When driving on land, the height of the amphibious wheels 4 relative to the hull 1 can be raised when encountering rough and uneven roads or obstacles, increasing the ground clearance of the rescue boat and improving the passability to avoid chassis bumping. When driving on mud, adjusting the height of the amphibious wheels 4 helps the rescue boat to adjust to the appropriate height according to the softness of the mud and the depth of the water, etc. At the same time, combined with the tire pressure self-adjusting technology of the amphibious wheels 4, the ground pressure can be reduced, the risk of sinking into soft mud can be reduced, and the center of gravity of the rescue boat can be changed by adjusting the height of the amphibious wheels 4, thereby enhancing the stability of driving.

[0027] Referring to Figure 1 and Figure 2As shown in the embodiment, the four-bar linkage floating wheel frame 6 includes a fork arm 61, one end of which is movably connected with the telescopic rod 7, the other end of which is movably connected with the support 5, and the middle part of which is rotatably connected with the main frame 2. The support 5 is movably connected with a connecting rod 62 at two axially symmetrical ends, and the other end of the connecting rod 62 is movably connected with the support 5.

[0028] Specifically, the rotation of the fork arm 61, the support 5 and the connecting rod 62 can be realized by the transverse reciprocating movement of the telescopic rod 7, so as to adjust the overall height of the support 5 and the amphibious wheel 4, adapt to various terrains, realize seamless switching, enhance the adaptability of the rescue boat, and provide support by the main frame 2.

[0029] Referring to Figure 1 and Figure 2 As shown in the embodiment, the bottom of the support 5 is fixedly provided with a sliding plate 8, the center of which is provided with a notch 81, and the amphibious wheel 4 is movably arranged in the notch 81, and the lower part of the amphibious wheel 4 partially penetrates the notch 81.

[0030] Specifically, when the hull 1 is moving, the sliding plate 8 is always in parallel with the bottom of the hull 1, and the height of the support 5 and the sliding plate 8 is adjusted by the four-bar linkage floating wheel frame 6, so that the bottom of the sliding plate 8 is always in contact with the water surface or the mud surface, and only a part of the amphibious wheel 4 is below the liquid surface or the mud surface. The water or mud under the sliding plate 8 is quickly rotated by the amphibious wheel 4 to provide forward driving force, the sliding plate 8 in contact with the water surface can provide a certain buoyancy for the whole hull 1, making it more convenient to drive the hull 1 on the water surface or the mud surface, and the notch 81 provides accommodation space for the amphibious wheel 4.

[0031] Referring to Figure 1 As shown in the embodiment, one end of the sliding plate 8 is provided with a liquid level sensor 9, and the liquid level sensor 9 is electrically connected with the servo cylinder 3.

[0032] Specifically, when the depth of the liquid level changes, the liquid level sensor 9 is used for monitoring, and the monitoring result is sent to one end of the servo cylinder 3. The height of the sliding plate 8 can be adjusted by moving the telescopic rod 7 driven by the servo cylinder 3, so that the bottom of the sliding plate 8 is always in contact with the liquid surface or the mud surface, which is more convenient for the rescue boat to travel.

[0033] Referring to Figure 1 As shown in the embodiment, the outer edge of the amphibious wheel 4 is provided with a land surface tread 10 for contacting and walking on hard land surface, and a hub motor is arranged inside the amphibious wheel 4 to provide walking power.

[0034] Specifically, the power of the amphibious wheel 4 comes from the hub motor arranged inside the amphibious wheel 4, and the land surface tread 10 arranged on the outer side of the amphibious wheel 4 can facilitate the amphibious wheel 4 to walk on the hard land surface, and can effectively enhance the anti-skid effect of the amphibious wheel 4.

[0035] Referring to Figure 1 , Figure 4 and Figure 5 , in the embodiment, the tri-wheel 4 is provided with sawtooth lugs 11 on both sides for water and mud.

[0036] Specifically, the tri-wheel 4 is provided with a plurality of sawtooth lugs 11 arranged in a ring shape on both sides, which can stir water flow and mud during rotation of the tri-wheel 4, increase the contact area with water flow and mud, and make the driving force stronger.

[0037] Referring to Figure 4 , in the embodiment, the support 5 is movably provided with a baffle 12 on one side of the tri-wheel 4, and the tri-wheel 4 is located inside the baffle 12.

[0038] Specifically, the tri-wheel 4 drives the whole boat body 1 to move in water or mud, which can splash water flow or mud, and the baffle 12 arranged outside the tri-wheel 4 can effectively prevent water flow or mud from splashing out and dirtying the operator's clothes.

[0039] Referring to Figures 4-6 , in the embodiment, the baffle 12 is provided with a notch 121, so that the baffle 12 is in a C shape.

[0040] Specifically, the sawtooth lug 11 is provided with a C-shaped baffle 12 outside to increase the driving force. When moving forward, the notch 121 of the C-shaped baffle 12 faces downward, the front of the notch 121 is attached to the sawtooth lug 11, and the sawtooth lug 11 can block the direction of water or mud, so that water or mud can only be thrown downward, and the sawtooth lug 11 can enter the notch 121 segment after passing through the C-shaped baffle 12 directly below, so that water or mud can quickly slide down the inclined surface of the sawtooth lug 11 and will not be taken upward, reducing resistance; similarly, when moving backward, the notch 121 of the C-shaped baffle 12 is turned to the lower front, and the wheel hub motor inside the tri-wheel 4 is controlled to rotate in reverse to make the tri-wheel 4 rotate in reverse, so that water or mud can only be thrown forward, and water flow or mud can also be prevented from splashing.

[0041] Referring to Figure 2 and Figure 3 , in the embodiment, the baffle 12 is provided with a ring-shaped rack 13 outside, and the support 5 is provided with a reversing motor 14 on one side, which drives the ring-shaped rack 13 to rotate synchronously with the baffle 12 through a driving gear 15.

[0042] Specifically, when the position of the gap 121 needs to be switched to adapt to whether the hull 1 is advancing or retreating, the gear 15 is driven to rotate by the reversing motor 14, the gear 15 meshes with the ring gear 13 to realize the rotation of the ring gear 13, and then the rotation of the baffle 12 is realized, the clockwise and counterclockwise rotation of the baffle 12 can be realized by the forward and reverse rotation of the gear 15, and the position of the gap 121 can be adjusted correspondingly.

[0043] Referring to Figures 4-6 In the embodiment, the baffle 12 is located at one side of the gap 121 and provided with a nozzle 16.

[0044] Specifically, when the tricycle wheel 4 drives the sawtooth denticle 11 to rotate to the gap 121, the relatively viscous mud can be stripped from the sawtooth denticle 11 by intermittently providing pulse spray through the nozzle 16, and the resistance of the tricycle wheel 4 during rotation can be reduced.
