Description

Technical Field

[0001] The invention relates to an all-terrain vehicle for traveling in water, in particular to a water propulsion device installed on a front vehicle and a rear vehicle. Background Art

[0002] A two-body all-terrain vehicle is a type of transportation equipment specially developed for complex and changeable roads. With the upgrading of demand and the need to cope with more terrain conditions, vehicles are required to have amphibious driving capabilities. Currently, the vehicle's water drive is mainly powered by the tracks of the chassis, and its water driving ability is very inefficient. By matching the shape and upgrading the tracks, the current fastest water driving speed is only close to 5km / h. In addition, some manufacturers have installed fixed water propellers at the rear of the vehicle. Through analysis, due to the vortex at the rear of the vehicle due to the shape of the body, the propulsion efficiency of the propeller is greatly reduced, so it is not a good solution.

[0003] In addition, the double-body all-terrain vehicle uses an articulated mid-position steering device, which can fully improve the vehicle's steering ability when driving on land, making the vehicle maneuverable and flexible, and fully activating the all-terrain driving ability. When driving in water, it can only rely on this steering method to adjust the direction of travel in the water. This snaking method in the water causes the vehicle's posture to change back and forth, and it is impossible to keep the forward lock, which greatly increases the difficulty of operation and pointing accuracy when reaching the other side. Therefore, driving in water has become the focus of drivers' complaints and seriously distracts drivers from observing the situation in the water. In the actual driving process in water, it often happens that the vehicle deviates from the green zone (designated landing point) when going ashore, and touches obstacles marked in the water due to steering difficulties in the water, which greatly reduces the vehicle's wading ability. Summary of the invention

[0004] The technical problem to be solved by the present invention is as follows: In view of the problems that an amphibious all-terrain vehicle has a slow speed on water and is difficult to turn, an all-terrain vehicle equipped with an underwater propeller is provided.

[0005] To achieve the above object, the present invention adopts the following technical solution:

[0006] A fast-moving amphibious all-terrain vehicle equipped with a water propulsion device comprises a front vehicle and a rear vehicle. A front vehicle propulsion device 2 is respectively installed on both sides of the front vehicle. The propeller assembly of the front vehicle propulsion device 2 is expanded or retracted by an oil cylinder. A rear vehicle propulsion device 4 is installed at the rear of the rear vehicle. A propulsion assembly is respectively installed at both ends of the base of the rear vehicle propulsion device 4. The extension and retraction of the two propulsion assemblies are controlled by a double-acting oil cylinder 402.

[0007] The front vehicle propulsion device 2 includes a propeller assembly and a front vehicle base 201. The front vehicle base 201 is a groove-shaped structure. The swing arm 202 of the propeller assembly is hinged on the front vehicle base 201 and is extended to 90° or retracted to 0° by a cylinder.

[0008] A horizontal cylinder 203 is installed in the front vehicle base 201. The movable end of the horizontal cylinder 203 has a hinge point d and is hinged to the first connecting rod 204. The distal end of the first connecting rod 204 has a hinge point f and is hinged to the second connecting rod 205 and the movable cylinder 206. The other end of the second connecting rod 205 is hinged to the hinge point e of the front vehicle base 201. The root of the rocker arm 202 is hinged to the hinge point a of the front vehicle base 201. The hinge point e is located between the horizontal cylinder 203 and the hinge point a and is close to the hinge point a; the other end of the movable cylinder 206 is hinged to the hinge point b in the middle of the rocker arm 202.

[0009] The rear vehicle propulsion device 4 includes a propeller assembly and a rear vehicle base 401. A propeller assembly is installed on each side of the rear vehicle base 401. A double-acting cylinder 402 is installed in the middle of the rear vehicle base 401. The two telescopic rods of the double-acting cylinder 402 drive the two propeller assemblies to extend and retract axially along the rear vehicle base 401.

[0010] The rear vehicle base 401 is a square tube structure. The double-acting cylinder 402 is installed in the middle position inside the rear vehicle base 401 and fixed by hinge point A. The thruster is installed at the end of the square tube structure. The square tube is inserted from both ends of the rear vehicle base 401. There is a hinge point B on the square tube. The telescopic end of the double-acting cylinder 402 is hinged to the square tube through the hinge point B. The distance from the hinge point B to the end of the square tube can ensure that the square tube and the rear vehicle base 401 remain matched when the double-acting cylinder 402 is extended to the deployed position.

[0011] After the two front vehicle propulsion devices 2 are fully deployed, the distance between the two turbines is L1, and after the rear vehicle propulsion device 4 is fully deployed, the distance between the two turbines is L2, L1>L2+R, R is the turbine diameter.

[0012] The installation positions of the two front vehicle propulsion devices 2 are higher than the rear vehicle propulsion device 4 .

[0013] Beneficial effects of the present invention:

[0014] The propeller can exert its efficient propulsion ability when driving in water, effectively avoid the eddy current interference caused by the vehicle's own shape, and fully improve the maneuvering speed in water; when driving on land, the propeller can be folded and stored inside the vehicle body, organically integrated, fully improving the vehicle's driving ability and meeting the vehicle's road driving and transportation standards, similar to the landing gear of an airplane.

[0015] When turning in water, lock the neutral steering device and control the speed difference of the propulsion devices on the left and right sides of the front vehicle to make the thrust on both sides of the vehicle body different, thus realizing the vehicle's underwater turning with clear direction, accurate underwater driving route and landing point.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] Embodiment 1:

[0028] like Figure 1 A fast-moving amphibious all-terrain vehicle equipped with a water propulsion device, the vehicle body 1 includes a front vehicle and a rear vehicle, and the front vehicle propulsion device 2 and the front vehicle propulsion device 3 are respectively provided on both sides of the front vehicle. The propeller assembly of the front vehicle propulsion device 2 is unfolded or retracted by a cylinder, and the rear vehicle propulsion device 4 is installed at the rear of the rear vehicle. A propulsion assembly is installed at each end of the base of the rear vehicle propulsion device 4, and the two propulsion assemblies are controlled to be extended and retracted by a double-acting cylinder 402. The propulsion assembly includes a turbine and a bracket for installing the turbine. When the two front vehicle propulsion devices 2 are fully unfolded, the distance between the two turbines is L1, and when the rear vehicle propulsion device 4 is fully unfolded, the distance between the two turbines is L2, L1>L2+R, and R is the turbine diameter. The installation position of the two front vehicle propulsion devices 2 is higher than that of the rear vehicle propulsion device 4.

[0029] The front vehicle propulsion device 2 includes a propeller assembly and a front vehicle base 201. The front vehicle base 201 is a groove-shaped structure. The swing arm 202 of the propeller assembly is hinged on the front vehicle base 201 and is extended to 90° or retracted to 0° by a cylinder.

[0030] A horizontal cylinder 203 is installed in the front vehicle base 201. The movable end of the horizontal cylinder 203 has a hinge point d and is hinged to the first connecting rod 204. The distal end of the first connecting rod 204 has a hinge point f and is hinged to the second connecting rod 205 and the movable cylinder 206. The other end of the second connecting rod 205 is hinged to the hinge point e of the front vehicle base 201. The root of the rocker arm 202 is hinged to the hinge point a of the front vehicle base 201. The hinge point e is located between the horizontal cylinder 203 and the hinge point a and is close to the hinge point a; the other end of the movable cylinder 206 is hinged to the hinge point b in the middle of the rocker arm 202.

[0031] The rear vehicle propulsion device 4 includes a propeller assembly and a rear vehicle base 401. A propeller assembly is installed on each side of the rear vehicle base 401. A double-acting cylinder 402 is installed in the middle of the rear vehicle base 401. The two telescopic rods of the double-acting cylinder 402 drive the two propeller assemblies to extend and retract axially along the rear vehicle base 401.

[0032] The rear vehicle base 401 is a square tube structure. The double-acting cylinder 402 is installed in the middle position inside the rear vehicle base 401 and fixed by hinge point A. The thruster is installed at the end of the square tube structure. The square tube is inserted from both ends of the rear vehicle base 401. There is a hinge point B on the square tube. The telescopic end of the double-acting cylinder 402 is hinged to the square tube through the hinge point B. The distance from the hinge point B to the end of the square tube can ensure that the square tube and the rear vehicle base 401 remain matched when the double-acting cylinder 402 is extended to the deployed position.

[0033] Embodiment 2:

[0034] The present invention is a fast-moving amphibious all-terrain vehicle and a water propulsion device, comprising a vehicle body 1, a propulsion device 2 arranged on the left side of the front vehicle body, a propulsion device 2 arranged on the right side of the front vehicle body, and a propulsion device 4 arranged on the rear vehicle body, such as Figure 1 , Figure 2 shown.

[0035] The propulsion device 2 is composed of a front vehicle base 201, a propeller assembly swing arm 202, a cylinder 203, a connecting rod 204, a connecting rod 205, a cylinder 206, and hinges a, b, c, d, e, and f, wherein hinges a, c, and e are inherent hinges on the front vehicle base 201, hinge b is a side hinge on the propeller assembly swing arm 202, and hinge c is the connection point between the front vehicle base 201 and the cylinder 203. Here, hinge c is similar to a square hole and square shaft connection and has no rotation function, that is, the cylinder 203 no longer rotates relative to hinge c after installation. Figure 3 , Figure 4 As shown (the two propulsion devices 2 are symmetrically installed and have the same function).

[0036] The propulsion device 4 comprises a base 401, a double-acting oil cylinder 402, a propeller assembly 403, a propeller assembly 404, and hinges A, B, C, and sliding connections D and E. The double-acting oil cylinder 402 is hinged to the base 401 through a hinge a and is built inside the base, the propeller assembly 403 is hinged to the double-acting oil cylinder 402 through a hinge B, the propeller assembly 404 is hinged to the double-acting oil cylinder 402 through a hinge C, the propeller assembly 403 is slidably connected to the base 401 (sliding connection pair D), and the propeller assembly 404 is slidably connected to the base 401 (sliding connection pair E), as shown in FIG. Figure 5 , Figure 6 , Figure 7 shown.

[0037] When the fast-moving amphibious all-terrain vehicle is traveling on land, the propulsion device is in a folded state, which does not affect the vehicle's driving width limit requirements, such as Figure 8 , Figure 2 When the fast-moving amphibious all-terrain vehicle is traveling in water, the propulsion device is in the deployed state, which fully provides the propulsion speed and turning ability of the all-terrain vehicle in water, such as Fig. 9 , Figure 1 Status shown.

[0038] The front vehicle base 201 and the base 401 are fixedly connected to the vehicle body 1 .

[0039] The working process of the front vehicle propulsion device from the folded state to the unfolded state is as follows: drive the oil cylinder 203 and the oil cylinder 206 to retract (which can be performed independently or separately). Conversely, the front vehicle propulsion device from the unfolded state to the folded state only needs to drive the oil cylinder 203 and the oil cylinder 206 to extend (which can be performed independently or separately).

[0040] The working process of the rear vehicle propulsion device from the folded state to the unfolded state is as follows: the double-acting oil cylinder 402 is extended. Conversely, the rear vehicle propulsion device from the unfolded state to the folded state is retracted by the double-acting oil cylinder 402.

[0041] When the vehicles need to go straight in the water, they only need to keep the propulsion devices on the left and right sides of the front vehicle rotating at the same speed, and keep the propulsion devices on both sides of the rear of the rear vehicle rotating at the same speed.

[0042] When the vehicle needs to turn in the water, the speed difference is achieved by controlling and changing the rotation speed of the propulsion devices on the left and right sides of the vehicle body, that is, the thrust on the left and right sides of the vehicle body is different, so as to achieve the vehicle's underwater turning.

[0043] The state of a vehicle driving in water is as follows Fig.10 shown.
