Description

Technical Field

[0001] This utility model relates to the field of lightweight and high-strength drone shell technology, and in particular to a lightweight and high-strength drone shell. Background Technology

[0002] Currently, drone shells are generally made of metal alloys or ordinary engineering plastics. While these meet basic strength requirements, they struggle to balance lightweight design with high strength. Excessive weight of metal shells significantly shortens flight time, while plastic shells are prone to deformation and cracking under complex operating conditions. In particular, poor heat dissipation in the battery compartment leading to module overheating and failure is a core pain point. Furthermore, fixed battery slots cannot accommodate battery modules of different sizes, hindering the functional expansion and maintenance efficiency of drones.

[0003] To address these issues, we propose a lightweight and high-strength drone shell. Utility Model Content

[0004] The purpose of this invention is to provide a lightweight and high-strength drone shell. When using this lightweight and high-strength drone shell, the main body is made of glass fiber reinforced nylon material. This reduces weight while significantly improving impact resistance through the directional arrangement of fibers. The hollowed-out mesh design of the mounting bracket and battery compartment forms a dual-channel heat dissipation system: the upper mesh accelerates airflow exchange with the control module, and the bottom support guides heat away from the battery module, simultaneously achieving weight reduction and improved temperature control efficiency. The locking bar and adjustable rotating blocks work together to overcome the limitations of traditional fixed battery compartments. Four sets of rotating blocks rotate synchronously within the mounting bracket via embedded rings, driving a screw to precisely adjust the height of the mounting bracket, allowing a single shell to accommodate battery modules of various thicknesses. The locking bar passes through the hollowed-out bracket slot and is secured with bolts, forming a three-point suspended fixing structure, effectively suppressing battery displacement caused by flight vibrations, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A lightweight and high-strength drone shell includes a shell body made of glass fiber reinforced nylon material. The upper end of the shell body is provided with a mounting bracket, the inner wall of which is provided with a perforated mesh. A connecting hole is also provided in the middle of the mounting bracket. A battery mounting slot is provided in the middle of the shell body. A perforated bracket is provided in the inner wall of the battery mounting slot. A locking strip is provided in the inner wall of the perforated bracket. A slot is provided in the inner wall of the perforated bracket, and fixing screw holes are installed in the inner walls at both ends of the locking strip.

[0007] In a further embodiment, a rotating block is provided on the inner wall of the mounting bracket, and an embedding ring is installed on the outer wall of the rotating block and is movably embedded in the inner wall of the mounting bracket.

[0008] In a further embodiment, a screw is provided at the lower end of the rotating block, and the screw is threadedly installed on the inner wall of the battery mounting slot.

[0009] In a further embodiment, a control module is provided at the upper end of the outer casing, while a battery module is installed in the inner wall of the outer casing.

[0010] In a further embodiment, the control module is bolted to a mounting bracket and connected to the battery module via wires passing through connection holes.

[0011] In a further embodiment, the battery module is movably inserted into the slot of the hollow bracket, and the locking strip passes through the battery module base and connects to the mounting bracket.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention utilizes a lightweight and high-strength drone shell made of glass fiber reinforced nylon material. This reduces weight while significantly improving impact resistance through directional fiber arrangement. The hollowed-out mesh design of the mounting bracket and battery compartment forms a dual-channel heat dissipation system: the upper mesh accelerates airflow exchange with the control module, while the bottom support guides heat away from the battery module, simultaneously achieving weight reduction and improved temperature control efficiency. The innovative combination of locking strips and adjustable rotating blocks overcomes the limitations of traditional fixed battery compartments. Four sets of rotating blocks rotate synchronously within the mounting bracket via embedded rings, driving screws to precisely adjust the bracket height, allowing a single shell to accommodate battery modules of various thicknesses. The locking strip passes through the hollowed-out bracket slot and is secured with bolts, forming a three-point suspended fixing structure that effectively suppresses battery displacement caused by flight vibrations.

[0022] 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.

[0023] Please see Figure 1-5A lightweight and high-strength drone shell includes a shell body 1. The core of this drone shell is a glass fiber reinforced nylon injection molded shell body 1. Its high strength and lightweight characteristics reduce the weight of the whole machine to 1 / 3 of that of traditional metal shells. The top of the shell body 1 is integrated with a mounting bracket 4. The surface of the mounting bracket 4 is opened with a honeycomb-shaped hollow grid 5, which reduces the structural load and promotes the heat dissipation and airflow circulation of the control module 2. The control module 2 is fixed to the surface of the mounting bracket 4 by bolts, and its power supply wires extend downward to the battery mounting slot 7 through the connection hole 6.

[0024] The battery mounting slot 7 is welded with a hollow bracket 14, and the bracket has a pre-set slot 9. During assembly, the battery module 3 is installed along the guide groove of the hollow bracket 14. Then, the locking strip 8 is inserted horizontally into the slot 9 and passes through the screw hole of the base of the battery module 3. Finally, it is tightened by the bolts of the screw holes 10 at both ends of the locking strip 8, forming a vibration-resistant three-point constraint system. The four corners of the inner wall of the mounting bracket 4 are embedded with rotating blocks 11. The embedded ring 12 on the outer periphery of the rotating block 11 is in clearance fit with the inner wall of the mounting bracket 4, allowing it to rotate along the axis.

[0025] When adjusting the height of the battery compartment, the four sets of rotating blocks 11 are rotated synchronously, and the screws 13 at the bottom of them rise and fall in the threads on the inner wall of the battery mounting slot 7, which drives the mounting bracket 4 to rise or fall as a whole. This design allows battery modules with a thickness of 20-35mm to be securely installed by locking strips 8, and the mesh structure of the hollow bracket 14 continuously dissipates battery heat.

[0026] The working principle of this utility model is as follows: As shown in the figure, it includes a shell body 1. The core of the shell of this drone is a glass fiber reinforced nylon injection molded shell body 1. Its high strength and lightweight characteristics reduce the weight of the whole machine to 1 / 3 of the traditional metal shell. The top of the shell body 1 integrates a mounting frame 4. The surface of the mounting frame 4 is opened with a honeycomb hollow grid 5, which reduces the structural load and promotes the heat dissipation and airflow circulation of the control module 2. The control module 2 is fixed to the surface of the mounting frame 4 by bolts. Its power supply wire extends downward to the battery mounting groove 7 through the connection hole 6.

[0027] The battery mounting slot 7 is welded with a hollow bracket 14, and the bracket has a pre-set slot 9. During assembly, the battery module 3 is installed along the guide groove of the hollow bracket 14. Then, the locking strip 8 is inserted horizontally into the slot 9 and passes through the screw hole of the base of the battery module 3. Finally, it is tightened by the bolts of the screw holes 10 at both ends of the locking strip 8, forming a vibration-resistant three-point constraint system. The four corners of the inner wall of the mounting bracket 4 are embedded with rotating blocks 11. The embedded ring 12 on the outer periphery of the rotating block 11 is in clearance fit with the inner wall of the mounting bracket 4, allowing it to rotate along the axis.

[0028] When adjusting the height of the battery compartment, the four sets of rotating blocks 11 are rotated synchronously, and the screws 13 at the bottom of them rise and fall in the threads on the inner wall of the battery mounting slot 7, which drives the mounting bracket 4 to rise or fall as a whole. This design allows battery modules with a thickness of 20-35mm to be securely installed by locking strips 8, and the mesh structure of the hollow bracket 14 continuously dissipates battery heat.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
