Description

Technical Field

[0001] This utility model relates to the field of drones, specifically a drone battery compartment support structure with buffer and shock absorption. Background Technology

[0002] With the widespread application of drones in aerial surveying, material delivery, and emergency rescue, the complexity of their operating environment places higher demands on battery safety. During flight, drones are affected by factors such as airflow disturbances, takeoff and landing impacts, and high-frequency motor vibrations, resulting in vibrations of different directions and frequencies. When traversing complex terrain or encountering emergencies, they may also be subjected to severe impacts. If these vibrations and impacts directly affect the battery, they can easily lead to loosening of internal electrodes, cracking of the casing, or even short circuits, seriously affecting the drone's endurance and flight safety, and shortening battery life.

[0003] Existing drone battery compartment support structures have significant deficiencies in shock absorption performance. Some designs rely solely on simple rigid frames to secure the battery, lacking effective cushioning components, allowing vibrations and impacts to be transmitted to the battery with almost no loss. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model aims to provide a drone battery compartment support structure with buffering and shock absorption. This application solves the aforementioned problems through structural innovation and functional integration. It adopts a double-layer vertical shock absorption structure combining V-shaped plastic ribs and spring washers. By utilizing the elastic deformation of the ribs and the dynamic compensation of the spring washers, it effectively absorbs vertical impacts during takeoff, landing, and flight. Rubber pads with hexagonal honeycomb holes are embedded at the four corners of the cabin and battery bracket. Through multi-directional elastic deformation and frictional damping, it achieves buffering of lateral and side vibrations. At the same time, the battery bracket is designed as a cage structure with heat dissipation holes, which ensures the battery is fixed and stable while also meeting heat dissipation requirements. The reinforcing ribs at the upper end of the ribs enhance the fatigue resistance of the structure and ensure the long-term stability of the shock absorption system, thereby comprehensively improving the safety and reliability of drone batteries in complex environments.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a drone battery compartment support structure with buffer and shock absorption, including a cabin, a battery bracket embedded inside the cabin, a battery fixed inside the battery bracket (3), and rubber pads embedded at the four corners of the cabin and the battery bracket.

[0008] Preferably, the upper part of the cabin is provided with two sets of ribs, the ribs are V-shaped, the included angle of the two arm-shaped parts is 140° to 150°, and the ribs are integrally formed with the cabin;

[0009] Preferably, the battery bracket is fixed to the rib by bolts, and a spring washer is provided between the battery bracket and the rib.

[0010] Preferably, the battery holder has a cage-like structure, and multiple sets of heat dissipation holes are provided on the side of the battery holder.

[0011] Preferably, the rubber pad has regularly arranged hexagonal honeycomb holes, and the hole depth accounts for 1 / 2 to 2 / 3 of the thickness of the rubber pad.

[0013] Preferably, the ribs are made of plastic, and the upper end of the ribs is provided with reinforcing ribs.

[0014] (III) Beneficial Effects

[0015] This invention achieves multi-dimensional technological breakthroughs through innovative structural design: a double-layer vertical shock absorption system is constructed using V-shaped plastic ribs and spring washers. The elastic deformation of the ribs absorbs low-frequency large impacts, while the spring washers compensate for high-frequency vibrations. Combined with the three-dimensional buffering of the four corner honeycomb pads, it can filter multi-directional vibrations and impacts from vertical, horizontal, and lateral directions during drone flight. The cage-type battery bracket, combined with a heat dissipation hole design, securely holds the battery while forming an efficient heat dissipation channel, preventing heat accumulation during shock absorption. The rib reinforcement and terminal fixing structure respectively improve the fatigue resistance of the shock absorption components and the stability of the battery's electrical connection, ultimately achieving a synergistic "shock absorption-heat dissipation-fixation" function for the battery. This significantly reduces the risk of structural damage and performance loss caused by battery vibration, extends battery life, and improves the flight safety and reliability of drones in complex environments.

[0024] The following will refer to the appendix in the example of this utility model. Figures 1-7 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] like Figure 1-7 As shown, this utility model provides a drone battery compartment support structure with buffer and shock absorption, including a cabin 1, a battery bracket 2 embedded inside the cabin 1, a battery 3 fixed inside the battery bracket 2, and rubber pads 4 embedded at the four corners of the cabin 1 and the battery bracket 2; and a top cover 5 fixed to the upper end of the cabin 1.

[0026] The cabin 1 serves as the main frame of the battery compartment support, providing fundamental support for the entire structure. Its internal space provides an environment for battery installation and operation. The battery bracket 2 adopts a cage-like structure to secure the battery 3, ensuring that the battery will not shake or shift during flight. Multiple sets of heat dissipation holes 21 on the sides effectively promote air circulation and dissipate the heat generated by the battery during use in a timely manner, preventing heat accumulation from affecting battery performance or causing safety hazards.

[0027] Battery 3 serves as the power source for the UAV, providing electrical energy for its flight and avionics. Its terminal 31 at the end engages with the terminal slot 13 and fixing post 14 at the end of the cabin 1, and is connected by bolts to achieve a stable electrical connection between the battery and the UAV's circuit system, ensuring reliable power transmission.

[0028] The rubber pad 4 is embedded in the four corners of the cabin 1 and the battery bracket 2. Its surface has regularly arranged hexagonal honeycomb holes, and the depth of the holes is 1 / 2 to 2 / 3 of the thickness of the rubber pad. This structural design allows the hole walls to undergo multi-directional elastic deformation when subjected to vibration or impact from different directions, thereby absorbing and dispersing energy and playing a role in buffering and shock absorption. At the same time, the friction between the rubber pad and the contact parts can suppress small relative displacements, reduce vibration noise, and reduce energy transfer efficiency, thus achieving all-round protection for the battery.

[0029] The top cover 5 is fixed to the upper end of the cabin 1 to seal the battery compartment, prevent dust, moisture and other foreign objects from entering, protect the battery from the influence of external environmental factors, and improve the safety and stability of battery use.

[0030] The upper part of the cabin 1 is provided with two sets of ribs 11. The ribs 11 are V-shaped, with the included angle of the two arm-shaped parts being 140° to 150°. The ribs 11 are made of plastic, and the upper end of the ribs 11 is provided with reinforcing ribs 111. The ribs 11 are integrally formed with the cabin. The battery bracket 2 is fixed to the ribs 11 by bolts, and a spring washer 12 is provided between the battery bracket 2 and the ribs 11.

[0031] Rib 11 is V-shaped with an included angle of 140° to 150° on both sides. It is integrally molded with the nacelle 1 and made of plastic. This angle design allows the rib to absorb energy through its own elastic bending deformation when subjected to vertical vibration or impact. The reinforcing rib 111 at its upper end increases the structural strength and rigidity of the rib, preventing deformation or damage due to frequent stress during long-term use and ensuring that the rib can continuously and stably perform its shock absorption function.

[0032] The spring washer 12 is disposed between the battery bracket 2 and the rib 11. When the drone vibrates during flight, the spring washer can absorb and buffer the vibration energy through its own elastic compression or expansion, forming a double-layer shock absorption system together with the rib to enhance the overall shock absorption effect. At the same time, the elastic tension of the spring washer can offset the small gaps at the bolt connection, prevent the bolts from loosening due to vibration, and ensure the reliability of the connection between the battery bracket and the rib.

[0033] The terminal slot 13 is used to initially position the battery terminal 31 to facilitate battery installation; the fixing post 14 is connected to the battery terminal 31 by bolts to firmly fix the battery in the cabin, ensuring that the battery will not be displaced due to vibration or other factors during flight, while ensuring a stable connection between the battery and the UAV circuit system, so that electrical energy can be transmitted safely and efficiently.

[0034] Working principle:

[0035] When a drone is in flight, takeoff, or landing, it will inevitably be subjected to vibrations and impacts from the outside world. This battery compartment support structure provides all-round protection for the battery through the following mechanisms:

[0036] Multi-stage shock absorption: Vibrations and impacts generated during UAV operation first act on the cabin 1. At this time, the V-shaped plastic ribs 11, with an angle of 140° to 150°, undergo bending deformation in the vertical direction due to their geometry and elastic material, converting most of the low-frequency vibration energy into their own elastic potential energy, achieving initial buffering. At the same time, the spring washers 12 between the battery bracket 2 and the ribs 11 further play a role, elastically compressing or extending under medium- and high-frequency vibrations to absorb the remaining vibration energy, forming a double-layer vertical shock absorption system with the ribs 11. The rubber pads 4 at the four corners of the cabin 1 and the battery bracket 2, with their hexagonal honeycomb structure, undergo multi-directional elastic deformation of the hole walls when subjected to lateral and side vibrations, absorbing and dispersing vibration energy in different directions, suppressing small relative displacements, reducing vibration noise, and jointly providing all-round shock absorption protection for the battery 3.

[0037] Secure Battery Fixation: Battery 3 is placed within a cage-like battery holder 2. The three-dimensional frame of the holder limits the battery from multiple directions, preventing it from shaking or shifting within the compartment. After the terminal 31 at the end of the battery is initially positioned and engaged with the terminal slot 13 inside the cabin 1, it is securely connected to the fixing post 14 by bolts. This dual mechanical and electrical fixing method ensures that the battery remains stable even under severe vibration and maintains a reliable electrical connection with the UAV's circuitry system, guaranteeing stable power transmission.
