Description

Technical Field

[0001] This utility model relates to the field of amphibious boats, specifically to a keel frame for an amphibious boat. Background Technology

[0002] Amphibious boats are hybrid vehicles that integrate the functions of automobiles, ships, and aircraft. Their keel frame, as the key structure for supporting and connecting the various functional modules, directly affects the stability and adaptability of amphibious boats on land, in water, and in the air.

[0003] In existing technologies, conventional keel frames typically have support ribs connected at intervals on the main keel. To ensure the structural strength of amphibious boats, thickened steel structures are often used. Additional steel is required at the locations connecting the wheels and rotors, resulting in a bulky overall structure that is difficult to meet the amphibious boat's flexible transformation requirements in different operating environments. Furthermore, it easily increases the weight of the amphibious boat's keel frame itself, leading to increased energy consumption and affecting its endurance in flight and maneuverability on land.

[0004] In summary, the existing amphibious boat keel frame design lacks sufficient consideration for lightweighting, making it difficult to achieve efficient adaptability in multi-functional environments. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a keel frame for amphibious boats, so as to solve the technical problem that the existing keel frames for amphibious boats lack sufficient lightweight considerations in structural design and are difficult to achieve efficient adaptability in multi-functional environments.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a keel frame for an amphibious boat, comprising a keel, with two ribs spaced apart at the front and rear ends of the keel, and no ribs in other positions; and a crossbeam, the ends of which are connected between two adjacent ribs via a first horizontal strut; both ends of the crossbeam are provided with rotor mounting slots for mounting rotors; and the lower ends of both ends of the crossbeam are connected to the two adjacent ribs via a diagonal bracing mechanism with a fixing frame; and the middle of the fixing frame is provided with a hub bearing hole for mounting hub bearings.

[0007] By adopting the above technical solution, two ribs are reinforced with a strut structure at the installation positions of the rotor and wheel axle to form a stable frame structure, and no extra ribs are connected at other positions of the keel, thereby effectively reducing the overall weight while ensuring structural strength and effectively improving the lightweight level of the amphibious boat.

[0008] The present invention is further configured such that a first diagonal brace is fixedly connected between the middle part of the crossbeam and the middle part of the two adjacent ribs.

[0009] Preferably, the first diagonal brace connects the ribs together as a whole, which can effectively strengthen the stability of the connection between the ribs and the keel.

[0010] The present invention is further configured such that the middle of each of the two adjacent ribs is connected to one end of a second horizontal support rod, the other ends of the second horizontal support rods are connected to each other, the fixing frame is installed at the top of the position where the two second horizontal support rods are connected to each other, and a second diagonal support rod is provided obliquely downward at the position where the first horizontal support rod is connected to the crossbeam, and the second diagonal support rod is fixedly connected to the top of the fixing frame.

[0011] Preferably, a stable wheel axle connection position is provided for the amphibious boat while keeping it as lightweight as possible.

[0012] The present invention is further configured such that each of the two adjacent ribs is fixedly connected with a connecting ear for installing a power battery at a position near the keel.

[0013] Preferably, the load of the heavy power battery inside the amphibious boat is distributed within the frame composed of ribs and struts to avoid deformation of the amphibious boat frame structure due to the weight of the power battery.

[0014] The present invention is further configured such that a frame strip is fixedly connected to the top of the keel and the top of each rib.

[0015] Preferably, the frame strips are used to provide mounting positions for the skin panels of the amphibious boat.

[0016] The present invention is further configured such that the frame strip is fixedly connected with ribs at intervals along a direction parallel to the ribs.

[0017] Preferably, the diameter of the ribs is significantly smaller than that of the ribs, and they are mainly used to enhance the structural strength of the amphibious boat's skin panels.

[0018] The present invention is further configured such that all the ribs connected to the keel are parallel to each other.

[0019] Preferably, this makes the center of gravity of the amphibious vessel's frame structure more stable.

[0020] The present invention is further configured such that the crossbeam is located in the middle of two adjacent ribs and its height is level with the top of the ribs, and the crossbeam is parallel to the two adjacent ribs.

[0021] Preferably, the two first diagonal braces and the first horizontal brace on both sides of the crossbeam are subjected to more balanced forces.

[0022] The present invention is further configured such that each rib is provided with four connecting ears, and the connecting ears on two adjacent ribs face opposite directions.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] The embodiments of this utility model will be described below based on its overall structure.

[0031] First embodiment: A keel frame for an amphibious vessel, please refer to Figure 1-5 It includes a keel 1, with two ribs 2 connected at intervals at the front and rear ends of the keel 1, and no ribs 2 are provided in other positions. Specifically, in this embodiment, a total of four ribs 2 are used.

[0032] It also includes a crossbeam 5, the end of which is connected to two adjacent ribs 2 via a first horizontal strut 4. Both ends of the crossbeam 5 are provided with rotor mounting slots 501 for mounting rotors. The lower ends of the crossbeam 5 are connected to the two adjacent ribs 2 via a diagonal bracing mechanism with a fixing frame 8. The middle of the fixing frame 8 is provided with a hub bearing hole 801 for mounting hub bearings.

[0033] Specifically, the first diagonal brace 3, the first horizontal brace 4, the crossbeam 5, and other structures used in this embodiment are all made of high-strength lightweight alloy materials, which further improves the strength and rigidity of the overall structure while taking into account the design requirements of lightweighting.

[0034] For details regarding the above embodiments, please refer to [link / reference]. Figure 1-2 The middle of the crossbeam 5 and the middle of the two adjacent ribs 2 are both fixedly connected by a first diagonal brace 3. The first diagonal brace 3 connects the ribs 2 into a whole, which can effectively strengthen the stability of the connection between the ribs 2 and the keel 1. The setting of the first diagonal brace 3 not only enhances the lateral connection strength between the ribs 2, but also makes the entire keel frame have a higher resistance to deformation when subjected to external forces. The combined use of the second horizontal brace 6 and the second diagonal brace 7 further improves the rigidity and stability of the overall structure, enabling the amphibious boat to maintain good operating performance in various environments.

[0035] For details regarding the above embodiments, please refer to [link / reference]. Figure 1-4 The middle of each of the two adjacent ribs 2 is connected to one end of the second horizontal support rod 6, and the other ends of the second horizontal support rod 6 are connected to each other. The fixing frame 8 is installed at the top of the position where the two second horizontal support rods 6 are connected to each other. The first horizontal support rod 4 is connected to the crossbeam 5 and a second diagonal support rod 7 is set diagonally downward. The second diagonal support rod 7 is fixedly connected to the top of the fixing frame 8, providing a stable wheel axle connection position for the amphibious boat while minimizing weight.

[0036] Specifically, the fixing frame 8 can not only securely connect the wheel hub bearing, but also effectively disperse the impact force from the wheel to the rib 2 and the crossbeam 5 through the second diagonal brace 7, thereby improving the overall frame's durability and load-bearing capacity.

[0037] Furthermore, each of the two adjacent ribs 2 is fixedly connected with a connecting lug 9 for installing the power battery near the keel 1. This allows the load of the relatively heavy power battery inside the amphibious boat to be distributed within the frame formed by the ribs 2 and the strut structure, preventing deformation of the amphibious boat frame structure due to the weight of the power battery. The connecting lugs 9 are symmetrically distributed on both sides of the keel 1, making the overall structure more evenly stressed and further improving the stability and fatigue resistance of the amphibious boat under complex working conditions. The power battery is firmly installed inside the frame through the connecting lugs 9, which not only lowers the center of gravity of the vehicle and improves driving safety, but also facilitates later maintenance and replacement.

[0038] Second embodiment: A keel frame for an amphibious vessel, please refer to Figure 1-5 Based on the first embodiment, the difference from the first embodiment is that the top of the keel 1 and the top of each rib 2 are fixedly connected to a frame strip 11. The frame strip 11 is used to provide the installation position of the skin panel of the amphibious boat. The frame strip 11 is fixedly connected to ribs 10 at intervals along the direction parallel to the rib 2. The diameter of the ribs 10 is significantly smaller than that of the rib 2, and is mainly used to enhance the structural strength of the skin panel of the amphibious boat.

[0039] For details regarding the above embodiments, please refer to [link / reference]. Figure 1-2 Each rib 2 connected to the keel 1 is parallel to each other, making the center of gravity of the amphibious boat's frame structure more stable. The crossbeam 5 is located in the middle of two adjacent ribs 2, and its height is level with the top of the rib 2. The crossbeam 5 is parallel to the two adjacent ribs 2, making the two first diagonal braces 3 and the first horizontal braces 4 on both sides of the crossbeam 5 more evenly stressed.

[0040] For details regarding the above embodiments, please refer to [link / reference]. Figure 1-4 Each rib 2 is provided with four connecting ears 9. The connecting ears 9 on two adjacent ribs 2 face opposite directions, which facilitates the connection of bolts between the power battery outer frame and the connecting ears 9.

[0041] Furthermore, the distance between two adjacent ribs 2 is greater than the width of the power battery, and the first diagonal brace 3 contacts the edge of the top of the power battery. The first diagonal brace 3, the keel 1, the ribs 2 and other structures provide good protection for the power battery, preventing it from falling or being damaged due to collision. This effectively improves the stability and safety of the power battery within the amphibious boat frame, allowing the battery to maintain a good fixed state even under complex working conditions.

[0042] The principle behind this invention for reducing the weight of the amphibious boat is as follows: The original 10 to 12 robust ribs 2 that needed to be spaced along the length of the keel 1 only require four ribs in this embodiment. The first diagonal brace 3, the first horizontal brace 4, and other structures between the four ribs 2 together form a stable frame structure, providing a stable mounting position for the rotor and wheel axle of the amphibious boat. Under the premise of ensuring the structural strength of the amphibious boat, the lighter first diagonal brace 3, the first horizontal brace 4, and other structures replace the original 6 to 8 ribs 2, greatly reducing the overall weight of the amphibious boat.

[0043] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
