[0002] In the field of unmanned equipment, aluminum alloy sheet structures are widely used due to their lightweight and corrosion resistance. Aluminum alloy sheet structures for unmanned equipment typically serve as load-bearing and protective components, requiring good strength, toughness, and stability to ensure the normal operation of the unmanned equipment in complex environments.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-5 As shown, a reinforced aluminum alloy sheet structure for unmanned equipment includes: an outer frame 1, an inner frame 2, an inner side plate 3, a lower base 4, a reinforcing support column 5, an auxiliary reinforcing column 6, small spiral reinforcing ribs 7, large spiral reinforcing ribs 8, a first curved reinforcing plate 9, and a second curved reinforcing plate 10. The outer frame 1 is arranged around the outermost layer of the structure, and the inner frame 2 and the inner side plate 3 are arranged inside the outer frame 1. The lower base 4 is located at the bottom of the structure. The reinforcing support column 5 connects the lower base 4 to the upper external component. The auxiliary reinforcing column 6 is distributed beside the reinforcing support column 5. The small spiral reinforcing ribs 7 and the large spiral reinforcing ribs 8 are arranged in specific areas inside the structure. The first curved reinforcing plate 9 and the second curved reinforcing plate 10 are installed in corresponding positions to enhance the structural strength.

[0023] The rest are used in the manufacturing of the body shell of an unmanned reconnaissance vehicle, where the reinforced aluminum alloy sheet structure of the unmanned equipment is applied.

[0024] First, the outer frame 1 is made of high-strength aluminum alloy and is integrally formed, surrounding the outermost layer of the vehicle body shell. Its shape is customized according to the outline of the reconnaissance vehicle, providing a basic protective frame for the entire vehicle body. The inner frame 2 and the inner side plate 3 are set inside the outer frame 1. Through precise size design, it is ensured that they can share the pressure with the outer frame 1 when subjected to external impact. The L-shaped structure design of the inner frame 2 and the outer frame 1 makes it more convenient to install some internal equipment. In addition, the structure that the bottom of the inner frame 2 is higher than the bottom of the outer frame 1 helps to prevent the accumulation of mud and sand and other debris at the bottom from causing corrosion or damage to the structure during vehicle operation.

[0025] The lower base 4 is located at the bottom of the vehicle body and bears the weight of the vehicle itself as well as various forces from the ground during driving. The reinforcing support columns 5 are evenly distributed between the lower base 4 and the equipment mounting platform above the vehicle body. Its circular cross-section design ensures stability when transmitting vertical loads. For example, when the unmanned reconnaissance vehicle is driving on rough terrain, the vertical impact force transmitted from the wheels is transmitted to the lower base 4 through the reinforcing support columns 5. The auxiliary reinforcing columns 6 are located on the side of the reinforcing support columns 5 to further disperse these impact forces and prevent local structures from deforming due to excessive force.

[0026] Small spiral reinforcing ribs 7 and large spiral reinforcing ribs 8 are installed in key parts inside the vehicle body, such as around the battery compartment and equipment compartment. These parts are prone to stress concentration due to vehicle vibration or external impact. Small spiral reinforcing ribs 7 absorb and disperse energy in a small area to protect the safety of the battery in the battery compartment; while large spiral reinforcing ribs 8 disperse vibration and impact forces in a larger area to ensure the integrity of the entire vehicle body structure.

[0027] The first curved reinforcing plate 9 and the second curved reinforcing plate 10 are installed on the sides and top of the vehicle body, which are prone to impact. The curvature of the plate is designed according to the wind resistance and stress distribution of possible side impacts when the reconnaissance vehicle is driving. In terms of material, a material with a hardness higher than that of the main body of aluminum alloy plate is selected. When the reconnaissance vehicle is hit by an object flying from the side, the curved reinforcing plate can effectively change the stress transmission path and is not easily deformed, thereby protecting the internal equipment of the vehicle body.

[0028] The rest will be used in the manufacturing of the fuselage of unmanned aerial vehicles (UAVs) using this reinforced aluminum alloy sheet structure.

[0029] The outer frame 1 is integrally formed and surrounds the outermost layer of the drone fuselage, providing the basic shape and protection for the fuselage. During the flight of the drone, the outer frame 1 directly bears the pressure and friction of the airflow. The inner frame 2 and the inner side plate 3 are inside the outer frame 1 and work together with the outer frame 1 to maintain the stability of the fuselage structure. When encountering strong airflow that causes uneven stress on the fuselage, the two work together to disperse the stress.

[0030] The lower base 4 is located at the bottom of the fuselage and bears the weight of the internal equipment of the drone. The reinforcing support column 5 connects the lower base 4 to the equipment installation area in the middle of the fuselage. Since the drone will be subjected to vibration and forces in different directions during flight, the reinforcing support column 5 transmits these forces to the lower base 4 to ensure the stability of the equipment installation area. The auxiliary reinforcing columns 6 are distributed on the side of the reinforcing support column 5. When the drone is performing rapid maneuvering flight or encountering sudden airflow disturbances, the auxiliary reinforcing columns 6 can promptly disperse additional stress and prevent structural damage.

[0031] Small spiral reinforcing ribs 7 and large spiral reinforcing ribs 8 are set in specific areas inside the fuselage, such as around the motor mounting area. The vibration generated when the motor is working can easily cause fatigue damage to the surrounding structure. Small spiral reinforcing ribs 7 absorb vibration energy in a small area near the motor, while large spiral reinforcing ribs 8 disperse the stress generated by vibration in a larger area of ​​the fuselage, ensuring the reliability of the fuselage structure.

[0032] The first curved reinforcing plate 9 and the second curved reinforcing plate 10 are installed on the parts of the fuselage surface that are susceptible to airflow impact. Their curvature is designed according to the aerodynamic characteristics of the UAV during flight, and the material has high hardness. When the UAV flies at high speed, the airflow exerts a large pressure on the fuselage surface. The curved reinforcing plate can change the stress transmission path and enhance the fuselage's ability to resist airflow pressure. At the same time, it can also protect the key components inside the fuselage when it encounters a small object impact, ensuring the normal flight of the UAV.

[0033] Working principle: When using this reinforced aluminum alloy plate structure for unmanned equipment, the outer frame 1 is set around the outermost layer of the structure. It is made of high-strength aluminum alloy and is integrally formed. As the outer boundary of the entire structure, it plays a basic protective and support role, withstands direct impact and pressure from the outside, and disperses and transmits it. The inner frame 2 and the inner side plate 3 are set inside the outer frame 1. Both the outer frame 1 and the inner frame 2 are L-shaped structures, and the bottom edge of the inner frame 2 is higher than the bottom edge of the outer frame 1. The inner frame 2 and the inner side plate 3 help the outer frame 1 to further define the internal space, while enhancing the overall rigidity of the structure. When bearing external loads, they work together with the outer frame 1 to share and transmit stress and reduce local deformation.

[0034] The lower base 4 is located at the bottom of the structure and is the basic support of the entire structure. It bears the weight of the upper components and the pressure transmitted to the bottom from the outside. The reinforcing support column 5 connects the lower base 4 and the upper components. Its cross-section is circular and it is evenly distributed between the lower base 4 and the upper components. Its main function is to bear the load in the vertical direction and transfer the weight of the upper components and the external vertical pressure to the lower base 4. At the same time, it enhances the stability of the structure in the vertical direction and prevents the structure from undergoing excessive deformation in the vertical direction when under stress. The auxiliary reinforcing columns 6 are distributed on the side of the reinforcing support column 5 to assist the reinforcing support column 5 in its work, further disperse and transfer the load, and improve the overall load-bearing capacity of the structure. Especially when subjected to uneven loads or local concentrated loads, the auxiliary reinforcing columns 6 can effectively reduce the stress on the reinforcing support column 5 and avoid damage to the local structure due to overload.

[0035] Small spiral stiffeners 7 and large spiral stiffeners 8 are installed in specific areas inside the structure. The spiral shape design allows them to absorb and disperse energy through the deformation of the spiral structure when subjected to external forces. Small spiral stiffeners 7 mainly address the stress concentration problem in small local areas inside the structure. Through their own elastic deformation and stress transmission, they reduce the possibility of cracks or damage caused by stress concentration in local areas. Large spiral stiffeners 8 are responsible for strengthening the structure over a larger area. When the structure is subjected to large external forces, such as impacts and vibrations, they disperse the external forces to the surrounding areas through their own structural characteristics, enhancing the overall deformation resistance and toughness of the structure and preventing overall structural failure due to excessive external forces.

[0036] The first curved reinforcing plate 9 and the second curved reinforcing plate 10 are installed in corresponding positions. Their curvature is designed according to the stress distribution of the structure, and the hardness of their materials is higher than that of the main body of the aluminum alloy plate. When the structure is under stress, the curved shape can effectively change the stress transmission path, so that the stress is more evenly distributed on the structure and avoids stress concentration. At the same time, due to their high material hardness, they are not easily deformed when subjected to external forces, thus providing support and constraint for the surrounding aluminum alloy plates, further enhancing the overall strength and stability of the structure. Especially when subjected to complex loads such as bending and torsion, the curved reinforcing plate can play an important role.

[0037] When the aluminum alloy sheet structure of the unmanned equipment is subjected to external loads, the outer frame 1 first bears and initially disperses part of the load. Then, the inner frame 2 and the inner side plate 3 jointly resist the external pressure. The load in the vertical direction is transmitted to the lower base 4 through the reinforced support column 5 and the auxiliary reinforced column 6. Inside the structure, the small spiral reinforcing ribs 7 and the large spiral reinforcing ribs 8 disperse the local and overall stresses to prevent the structure from being damaged due to stress concentration. The first curved reinforcing plate 9 and the second curved reinforcing plate 10 enhance the overall strength and stability of the structure by changing the stress transmission path and their own high hardness. All components work together to ensure the normal use and stable performance of the reinforced aluminum alloy sheet structure of the unmanned equipment under complex working conditions.

Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
