Technical Field

The invention relates to a wave-proof plate device, a control method and an amphibious vehicle thereof, belonging to the field of vehicle engineering.

Background

The amphibious vehicle combines the dual performance of the vehicle and the ship, has good amphibious traffic performance, and is an important transportation tool. In order to improve the navigation performance of vehicles in water, a breakwater device is required.

The traditional breakwater device adopts an upward-tipping unfolding mode, and adopts a manual or manual hydraulic pump to realize unfolding and retraction. The method of upward tilting, turning and unfolding enables the wave-proof plate to be folded and then covered above the front part of the vehicle body, and is inconvenient for the internal maintenance of the power cabin at the front part of the vehicle body; (2) the driver manually operates or manually pulls the hand pump pressing rod to unfold, and the retracting operation ensures that the working intensity of the driver is high; (3) the time for unfolding and retracting the wave-proof plate is long, and the action is about 2 min.

Prior art, such as chinese patent, application number: CN2013202155440, publication No.: CN203432465U discloses a surfboard operating mechanism for amphibious wheel type armored vehicles. The patent describes a structure for driving the body of the breakwater to slide up and down by using a winch, and the structure determines that the fixed structure is too close to the bottom of the breakwater, so that the cantilever part is too long in the working state of the breakwater, the stability is not strong, and the breakwater cannot bear too large acting force. When the amphibious vehicle is sailing on the sea, the potential safety hazard exists when the vehicle is tested by sea storms. In addition, the use state of the wave guard plate only has one angle, and the angle cannot be adjusted according to factors such as sea waves and the like, so that the minimum resistance is obtained.

Application No.: CN202110410775, publication No.: CN 113022243A; application No.: CN202110410778x, publication No.: CN 113147291A discloses an amphibious vehicle. The folding breakwater referred to in this patent can adjust the deployment angle by two sets of electric push rods, thereby reducing the resistance when the vehicle is moving underwater. But when the vehicle runs on land, the upper edge of the wave-proof plate is still higher than the outer surface of the top deck of the vehicle body after the two groups of electric push rods are completely retracted. Therefore, the use of the wave guard structure has certain limitation, if the vehicle is a manned vehicle, the retracted wave guard structure can block the view of the driver, interfere with the driving on the land and possibly influence the driving safety.

Application No.: CN2020115208949, publication No.: CN 112549882A, an electrically driven breakwater is disclosed. This patent relates to a flip-up breakwater device that retracts above the upper first deck when the breakwater is not in use. However, most of the engines of special vehicles are located at the front of the vehicle, and the daily maintenance of the engines needs to unfold the breakwater first and then open the engine compartment cover for maintenance.

Application No.: CN2010100501098, publication No.: CN106134341B discloses a wave plate mechanism for wheeled armored vehicle. The control mechanism of the breakwater is simple and practical in structure, is of an upturning structure, and can be used for daily maintenance of the engine only by opening the breakwater. In addition, the mechanism is fully operated manually for unfolding and folding, so that the workload of operators is increased; the vehicle can not be unfolded and retracted in the running motion state, and the possibility of casualties is inevitably increased if war and parking operation occur.

In addition, the prior art, such as chinese patent, its application number: CN201320023049x (CN201310016201.6), publication No.: CN203063604U (publication number: CN103112327A), discloses a front breakwater of an amphibious vehicle; publication No.: JP hei 2-185811A, US2009/0124142a1, CN213414977U and journal "journal of university of beijing" volume 23, first phase, authors: liu shuyan etc. discloses an amphibious vehicle of improved design on water performance test research, however, above-mentioned prior art all relates to breakwater and structure, but above-mentioned prior art all can not realize not needing to open breakwater, expand, withdraw drawbacks such as action separation control when the daily maintenance of power compartment inside, increases driver's working strength.
