Description

Technical Field

[0001] This invention belongs to the field of vehicle engineering technology, specifically relating to a closed modular cargo compartment for amphibious vehicles. Background Technology

[0002] Amphibious vehicles combine the capabilities of both cars and ships, allowing them to travel on land like automobiles and navigate waterways like boats. Due to their superior amphibious capabilities, they can cross rivers, lakes, and seas without being restricted by bridges or other vessels, making them increasingly important in transportation. Currently, amphibious vehicles, used as transport vehicles, employ open cargo holds similar to those of land vehicles for easy loading and unloading. This type of cargo hold is suitable for operations on inland rivers and lakes. However, when used at sea, the unpredictable sea conditions and the influence of wind, waves, and currents mean that the buoyancy reserve of open-top amphibious vehicles is severely insufficient, making it easy for seawater to enter the cargo hold and seriously threatening maritime safety. Currently, there is also a fully enclosed cargo hold type for amphibious vehicles, equipped with a rear door for loading and unloading cargo from the rear. While this type solves the safety problem on water, the size of the rear door limits cargo loading and unloading to manual labor, making it extremely inconvenient for handling large quantities of cargo. Summary of the Invention

[0003] In view of this, the present invention provides a closed modular cargo hold for amphibious vehicles, which is suitable for amphibious vehicle transportation operations, improves the vehicle's sea state adaptability and buoyancy reserve, facilitates cargo loading and unloading, and improves the vehicle's water safety.

[0004] This invention is achieved through the following technical solution:

[0005] An enclosed modular cargo compartment for an amphibious vehicle includes: a hull, a top hatch, a rear hatch, and a front cover.

[0006] The cabin is a rectangular box with a mounting hole at the bottom through which it is mounted on the amphibious vehicle body; the top of the cabin has a top opening, the rear of the cabin has a rear opening, and the front of the cabin has a front opening.

[0007] The top hatch is installed at the top opening of the hold, providing a passage for transporting bulk cargo into and out of the hold; the stern hatch is installed at the stern opening of the hold, providing a passage for personnel to get on and off and for loading and unloading small cargo into and out of the hold; the front cover is installed at the front opening of the hold, providing a passage for personnel to enter the hold from the front for work and inspection; the hold with the top hatch, stern hatch, and front cover installed forms a closed cargo hold.

[0008] Furthermore, the top hatch includes four top doors: a front top door, a rear top door, a left top door, and a right top door. Each top door is connected to the hatch body via a hinged joint. The front and rear top doors are identical, as are the left and right top doors. The left and right top doors are joined together to form a rectangular central top door, while the front and rear top doors are located on opposite sides of the central top door, forming a rectangular top hatch.

[0009] The top hatch of the hull is equipped with an H-shaped support beam. The H-shaped support beam is an H-shaped structure composed of two longitudinal beams and one transverse beam, and the three beams are detachably connected to each other with bolts. The H-shaped support beam is detachably installed on the top hatch opening with bolts. The H-shaped support beam is used to support the top hatch door. The transverse beam of the H-shaped support beam corresponds to the joint of the left top door and the right top door, and is used to support the left top door and the right top door. The two longitudinal beams of the H-shaped support beam correspond to the joint of the front top door and the middle top door on one side, and the joint of the rear top door and the middle top door on the other side, respectively, and are used to support the front top door and the rear top door.

[0010] Furthermore, the top compartment opening has an L-shaped folded edge structure, meaning the edge of the top compartment opening has an upward-protruding folded edge; the three beams of the H-shaped support beam all have a channel-shaped structure, meaning the cross-section of each beam is U-shaped. When the H-shaped support beam is installed at the top compartment opening, the two folded edges of the U-shaped structure of each beam are set upwards; the edge of each top door has an L-shaped folded edge structure, meaning the edge of each top door has a downward-protruding folded edge when fastened. The folded edges of the top compartment opening, the H-shaped support beam, and the top door are all covered with sealing strips. When the top door is fastened to the top compartment opening and supported on the H-shaped support beam, the folded edges of the top compartment opening and the H-shaped support beam cooperate with the folded edges of the top door, and the sealing strips on the two cooperating folded edges abut against each other.

[0011] Furthermore, all three beams of the H-shaped support beam adopt a channel structure, with the two folded edges of the U-shaped structure of each beam facing upwards. The cavity formed by the two folded edges of each beam and the bottom plate forms a water passage channel, and the water passage channels of the three beams are interconnected.

[0012] Furthermore, the cabin adopts a structure of a supporting frame plus a thin-shell skin. The supporting frame includes side ribs and top ribs. The side ribs enclose the side frame of the cabin, and the top ribs are fixed to the top of the side frame of the cabin. The thin-shell skin covers the outside of the supporting frame and is made of composite material or aluminum alloy.

[0013] Furthermore, each top door adopts a structural form with a supporting frame and a thin-shell skin.

[0014] Furthermore, the left top door, right top door, front top door, and rear top door are all equipped with a pressure lock and a lifting handle.

[0015] Furthermore, the left top door, right top door, front top door, rear top door and tailgate are all equipped with door alarm devices, which are connected to the vehicle display and control terminal.

[0016] Furthermore, the annular planar area at the top of the cabin, excluding the top cabin opening, serves as a working passage for personnel, with a width of 0.5 meters.

[0017] Furthermore, the side of the cabin is equipped with multiple sets of observation windows.

[0018] Beneficial effects:

[0019] (1) When transporting large quantities of goods, the top hatch can be opened to expose the top hatch opening and complete the loading and unloading of large quantities of goods; when transporting small goods or personnel, the rear hatch can be used to enable personnel to get on and off and goods to be loaded and unloaded, greatly improving the loading and unloading efficiency of goods; when sailing at sea, the cargo hold can be closed to effectively improve the buoyancy reserve and wind and wave resistance of the whole vehicle and improve the water safety of the vehicle; and the cargo hold of the present invention is an independent modular cargo hold. When the cargo hold needs to be replaced or repaired, the entire cargo hold can be removed from the vehicle as a separate module for repair.

[0020] (2) When the front top door, rear top door, left top door and right top door of the present invention are all opened, the loading and unloading area of ​​the top compartment opening can be completely released by disassembling the H-shaped support beam, thereby facilitating the entry and exit of bulk cargo into and out of the compartment.

[0021] (3) The top compartment opening, the H-shaped support beam and the folded edge of the top door of the present invention are all covered with sealing strips. When the top door is fastened to the top compartment opening and supported on the H-shaped support beam, the folded edge of the top compartment opening and the folded edge of the H-shaped support beam are matched with the folded edge of the top door, and the sealing strips on the two matching folded edges abut against each other. The sealing strips can effectively ensure the watertightness after the top door is closed, prevent water from entering the cargo compartment, and improve the vehicle's buoyancy reserve and safety performance.

[0022] (4) The cavity formed by the two folded edges and the bottom plate of each of the H-shaped support beams of the present invention forms a water passage channel. The water passage channels of the three beams are connected. When the vehicle is driving in the sea, the water passage channels of the three beams can promptly drain the water that is splashed or splashed onto the top of the cabin, preventing water from seeping into the cargo hold and further improving the vehicle's buoyancy reserve and safety performance.

[0023] (5) The cabin and each top door of the present invention adopt a structure of supporting frame plus thin shell skin, which can reduce weight while ensuring strength, thereby reducing the impact on the overall vehicle weight and water mobility performance.

[0024] (6) The clamping lock of each top door of the present invention can press the top door and the cabin together to achieve a sealing effect, and the lifting handle of each top door can facilitate the opening and closing of the top door.

[0025] (7) Each top door and tail door of the present invention is equipped with a door alarm device. The door alarm device can promptly notify the driver of the current opening and closing status of each top door and tail door, ensuring the safety of the vehicle when navigating on water.

[0026] (8) The top of the cabin of the present invention is provided with a working passage for personnel, which makes it convenient for personnel to stand on the top of the cabin to carry out operations and improve loading and unloading efficiency.

[0027] (9) The side of the cabin of the present invention is provided with multiple sets of observation windows. On the one hand, the external environment can be observed through the observation windows, and on the other hand, light can enter the cabin through the observation windows to ensure lighting conditions.

[0040] The stern door 2 is installed at the stern opening of the hull 1, and the front cover plate 3 is installed at the front opening of the hull 1; the hull 1 with the top door, stern door 2 and front cover plate 3 installed forms a closed cargo hold.

[0041] After the four sets of top doors are opened, it is convenient for bulk cargo to enter and exit the cabin 1. After the front cover plate 3 is opened, it is convenient for personnel to enter the cabin 1 from the front for work and inspection. After the tail hatch 2 is opened, it is convenient for personnel to get on and off and for small cargo to be loaded and unloaded into and out of the cabin 1.

[0042] In one specific embodiment, see Appendix Figure 3 The cabin 1 adopts a structure of supporting frame plus thin shell skin. The supporting frame includes side support ribs 16 and top support ribs 17. The side support ribs 16 enclose the side frame of the cabin 1, and the top support ribs 17 are fixed to the top of the side frame of the cabin 1. The thin shell skin covers the outside of the supporting frame and is made of composite material or aluminum alloy. The cabin 1 with supporting frame plus thin shell skin structure can reduce weight while ensuring strength, thereby reducing the impact on the overall vehicle weight and water mobility performance.

[0043] In one specific embodiment, see Appendix Figure 4 Each top door adopts a structural form with a supporting frame and a thin-shell skin.

[0044] In one specific embodiment, an H-shaped support beam 13 is installed at the top compartment opening 14 of the cabin 1, as shown in the attached figure. Figure 5As shown, the H-shaped support beam 13 is an H-shaped structure composed of two longitudinal beams and one transverse beam, and the three beams are detachably connected to each other by bolts. The H-shaped support beam 13 is detachably installed on the top hatch opening 14 by bolts. The H-shaped support beam 13 is used to support the top hatch door.
