Description

Technical Field

[0001] This invention relates to the field of vehicle engineering technology, and more particularly to the field of all-terrain vehicle technology, specifically to a quick-mount propulsion structure for an all-terrain vehicle. Background Technology

[0002] All-terrain vehicles are amphibious multi-functional engineering vehicles with high off-road capability, high flexibility, and reliable protection.

[0003] Existing all-terrain vehicles can only propel themselves in water using their tracks, allowing them to float on water at slow speeds. Furthermore, the compact design of the rear frame of existing all-terrain vehicles makes it impossible to install and maintain the fuel tank if a propeller bracket is added. Installing a propeller on an all-terrain vehicle reduces its departure angle, affecting its climbing ability and off-road capability. Additionally, the compact design makes it difficult to install and maintain the propeller motor piping. Summary of the Invention

[0004] The main objective of this invention is to propose a quick-mount propulsion structure for all-terrain vehicles, aiming to solve the aforementioned technical problems.

[0005] To achieve the above objectives, this invention proposes a quick-mount propeller structure for all-terrain vehicles, including a propeller assembly and a folding assembly. The propeller assembly is installed to the rear of the all-terrain vehicle via the folding assembly. When the propeller is in operation, the propeller assembly is folded to a horizontal position via the folding assembly, so that the thrust direction of the propeller assembly is horizontal and rearward. When the propeller is not in operation, the propeller assembly is folded upward via the folding assembly, so that the propeller assembly is retracted upward.

[0006] Preferably, the folding assembly includes a vehicle-mounted bracket and a thruster mounting bracket; the vehicle-mounted bracket is disposed on the rear of the all-terrain vehicle; the thruster assembly is mounted on the thruster mounting bracket; and the vehicle-mounted bracket and the thruster mounting bracket are hinged together.

[0007] Preferably, the vehicle-mounted bracket includes multiple parallel first rods; the first ends of the multiple first rods are connected to the rear of the all-terrain vehicle, and the second ends of the multiple first rods are connected to a first connecting plate; the pusher mounting bracket includes multiple parallel second rods; the first ends of the multiple second rods are connected to a second connecting plate, and the second ends of the multiple second rods are connected to a transverse rod; the number of first rods is the same as the number of second rods; the second ends of the first rods are connected to the first ends of the second rods by hinges.

[0008] Preferably, a limiting plate is provided on the second connecting plate; when the pusher is in working state, the first rod and the second rod are in a horizontal state, and the first connecting plate and the second connecting plate are fixed by a bolt assembly; when the pusher is not in working state, the second rod folds upward around the hinge, and the first connecting plate and the limiting plate are fixed by a bolt assembly.

[0009] Preferably, a motor mounting plate is provided on the transverse rod, and a flange plate is provided on the outer cylindrical surface of the thruster on the thruster assembly; the flange plate and the motor mounting plate are connected by screws.

[0010] Preferably, an arc-shaped slot is provided on the motor mounting plate, and the outer cylindrical surface of the thruster on the thruster assembly is disposed in the slot.

[0011] Preferably, the top of the motor mounting plate is bent to form a bent portion, which is then hung on the transverse rod and welded.

[0012] Preferably, the first rod, the second rod, and the transverse rod are all made of hollow square tubes.

[0013] Preferably, the propulsion assembly includes a hydraulic motor and a propulsion unit, the propulsion unit being connected to the hydraulic motor, and a quick-connect coupling being provided on the hydraulic motor for connecting to an interface on the rear body of the all-terrain vehicle.

[0014] Preferably, there are two hydraulic motors and two thrusters, with one thruster corresponding to each hydraulic motor.

[0015] Due to the adoption of the above technical solution, the beneficial effects of the present invention are as follows:

[0016] (1) By installing a propulsion assembly on the rear body of the all-terrain vehicle, the present invention can greatly improve the speed of the all-terrain vehicle on water, and overcome the problem that the all-terrain vehicle can only rely on the tracks to propel itself slowly when driving in water in the prior art.

[0017] (2) In this invention, the propeller assembly is installed at the rear of the all-terrain vehicle via a folding assembly. When in use, the propeller assembly is lowered, and when not in use, the propeller assembly is rotated and raised and folded up, providing space for the fuel tank to be installed and maintained. In addition, when the propeller assembly is not in use, the propeller assembly can be raised via the folding assembly to increase the vehicle's departure angle, so that the addition of the propeller assembly does not affect the all-terrain vehicle's climbing ability and passability.

[0029] like Figure 1 As shown, an all-terrain vehicle quick-mount propulsion structure includes a propulsion assembly 300 and a folding assembly. The propulsion assembly 300 is installed to the rear of the all-terrain vehicle via the folding assembly.

[0030] When the thruster is in operation, the thruster assembly 300 is folded to a horizontal state by the folding assembly so that the thrust direction of the thruster assembly 300 is horizontal and backward.

[0031] When the thruster is not in operation, the thruster assembly 300 is folded upward by the folding component, so that the thruster assembly 300 is retracted upward.

[0032] like Figure 1 As shown, in this embodiment, the folding assembly includes a vehicle-mounted bracket 100 and a thruster mounting bracket 200; the vehicle-mounted bracket 100 is disposed on the rear of the all-terrain vehicle; the thruster assembly 300 is mounted on the thruster mounting bracket 200; the vehicle-mounted bracket 100 and the thruster mounting bracket 200 are hinged together.

[0033] Specifically, the vehicle-mounted bracket 100 includes multiple parallel first rods 1; the first ends of the multiple first rods 1 are connected to the rear of the all-terrain vehicle, and the second ends of the multiple first rods 1 are connected to the first connecting plate 8. The pusher mounting bracket 200 includes multiple parallel second rods 10; the first ends of the multiple second rods 10 are connected to the second connecting plate 14, and the second ends of the multiple second rods 10 are connected to the transverse rod 13; the number of first rods 1 is the same as the number of second rods 10; the second ends of the first rods 1 and the first ends of the second rods 10 are connected by hinges 7; one side of the hinge 7 is fixed to the second end of the first rod 1 by a first screw 6 and a first washer 5, and the other side of the hinge 7 is fixed to the first end of the second rod 10 by a first screw 6 and a first washer 5.

[0034] Combination Figure 2 and Figure 4 As shown, a limit plate 15 is provided on the second connecting plate 14; when the thruster is in working state, the first rod 1 and the second rod 10 are in a horizontal state, and the first connecting plate 8 and the second connecting plate 14 are fixed by a bolt assembly. After the first connecting plate 8 and the second connecting plate 14 are fixed by the bolt assembly, the thruster mounting bracket 200 can be prevented from rotating around the hinge 7 during the use of the thruster assembly 300, so as to always ensure that the thrust of the thruster assembly 300 is horizontal and backward. When the thruster is not in operation, the second rod 10 folds upward around the hinge 7, and the first connecting plate 8 is fixed to the limiting plate 15 by a bolt assembly. The limiting plate 15 is located on the side of the second connecting plate 14, and the surface of the limiting plate 15 is perpendicular to the surface of the second connecting plate 14. When the second rod 10 folds upward 90 degrees around the hinge 7, the bolt assembly fixes the limiting plate 15 to the first connecting plate 8, ensuring that the second rod 10 remains in an upward folded state. This means the thruster mounting bracket 200 remains folded upward, keeping the thruster assembly 300 in a retracted state and preventing the thruster assembly 300 from falling back down on its own. In this embodiment, the bolt assembly includes a bolt 9, a nut 2, an elastic washer 3, and a gasket 4.

[0035] Combination Figure 1 As shown, the thruster assembly 300 includes a hydraulic motor 18 and a thruster 19. The thruster 19 is connected to the hydraulic motor 18. A quick-connect coupling 16 is provided on the hydraulic motor 18 for connecting to an interface on the rear body of the all-terrain vehicle. Specifically, there are two hydraulic motors 18 and two thrusters 19, with one thruster 19 corresponding to each hydraulic motor 18. A motor mounting plate is provided on the transverse rod 13, and a flange plate 191 is provided on the outer cylindrical surface of the thruster 19 on the thruster assembly 300; the flange plate 191 is connected to the motor mounting plate by screws. Figure 1 As shown, specifically, the flange 191 is connected to the motor mounting plate using a second screw 20. In this embodiment, there are two motor mounting plates: a right motor mounting plate 11 and a left motor mounting plate 12. Arc-shaped slots 121 are provided on both the right and left motor mounting plates 11 and 12, and the outer cylindrical surface of the thruster 19 on the thruster assembly 300 is disposed within these slots 121. The slots 121 are used to position the thruster 19. Furthermore, the thruster assembly 300 is installed by connecting the flange 191 to the motor mounting plate using screws. This screw connection is a detachable fixing structure, facilitating the installation and removal of the thruster assembly 300.

[0036] Combination Figure 1 As shown in this embodiment, the quick-connect connector 16 is used to quickly connect or disconnect with the interface on the rear body of the all-terrain vehicle. There are three quick-connect connectors 16: the oil inlets of the two hydraulic motors 18 are connected via hydraulic hoses 17 and share one quick-connect connector 16; the oil return ports of the two hydraulic motors 18 are connected via hydraulic hoses 17 and share another quick-connect connector 16; and the oil drain ports of the two hydraulic motors 18 are connected via hydraulic hoses 17 and share a third quick-connect connector 16. The structure of the oil inlets, oil return ports, and oil drain ports of the two hydraulic motors 18 sharing quick-connect connectors 16 effectively reduces the number of quick-connect connectors 16 used, facilitating quick connection or disconnection between the propeller assembly 300 and the interface on the rear body of the all-terrain vehicle. When the propeller is in the working state, it is quickly connected to the interface on the rear body of the all-terrain vehicle via the quick-connect connector 16; when the propeller is not in the working state, it is quickly disassembled from the interface on the rear body of the all-terrain vehicle via the quick-connect connector 16, facilitating the upward folding of the propeller assembly 300.

[0037] Combination Figure 2 As shown, the tops of the right motor mounting plate 11 and the left motor mounting plate 12 are bent to form bent portions 122. The right motor mounting plate 11 and the left motor mounting plate 12 are respectively hung on the transverse rod 13 and welded. By setting the bent portions 122, it is convenient to connect the motor mounting plate and the transverse rod 13, and it can increase the contact area to ensure the strength of the weld, thereby ensuring the reliability of the thruster mounting bracket 200.

[0038] In this embodiment, the first rod 1, the second rod 10, and the transverse rod 13 are all hollow square tubes. Using square tubes helps to reduce the weight of the entire folding assembly, and the materials are readily available and easy to process and manufacture.

[0039] The all-terrain vehicle quick-mount propeller structure provided by this invention allows for manual adjustment of the propeller assembly 300 when it is folded downwards or upwards. The specific adjustment method is as follows:

[0040] When the thruster is not in operation, the thruster assembly 300 is in the upward retracted state. At this time, the first connecting plate 8 and the limiting plate 15 are connected and fixed by bolts 9, nuts 2, elastic washers 3 and gaskets 4 to form a limiting effect, so that the second rod 10 and the first rod 1 are always in a perpendicular state.

[0041] When the thruster is needed, manually adjust it by first removing nut 2, taking off bolt 9, and disconnecting the bolt connection between connecting plate 8 and limiting plate 15. Then, manually adjust the thruster mounting bracket 200 and the thruster assembly 300 to fold downward around hinge 7, so that the second connecting plate 14 abuts against the first connecting plate 8. Then, use bolt 9, nut 2, elastic washer 3, and gasket 4 to fix the second connecting plate 14 and the first connecting plate 8. At this time, the thruster assembly 300 is in a horizontal state. Then, the quick-connect connector 16 can be connected to the interface on the rear body of the all-terrain vehicle.

[0042] When the thruster is not needed, remove the quick-connect connector 16 from the interface on the rear body of the all-terrain vehicle. At the same time, remove the bolts 9, nuts 2, elastic washers 3 and shims 4 between the second connecting plate 14 and the first connecting plate 8. By manually folding, fold the thruster mounting bracket 200 and the thruster assembly 300 upwards by 90 degrees around the hinge 7. Then, connect and fix the connecting plate 8 and the limiting plate 15 with the bolts 9, nuts 2, elastic washers 3 and shims 4.

[0043] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
