Description

Technical Field

[0001] This utility model relates to the field of drones, and in particular to a shockproof and spark-proof buffer bracket for drone battery packs. Background Technology

[0002] Drone vibration refers to the vibration or shaking of the fuselage during flight caused by various reasons. This phenomenon can affect the performance and control of the drone, and may even lead to flight accidents. Therefore, reducing drone vibration is of great significance for ensuring flight safety. Drone vibration may be caused by factors such as structural instability, failure of the flight control system, and strong winds. Among these, structural instability is the most significant cause of vibration. This is especially true during high-speed flight or in complex airflow environments, where structural vibration becomes more pronounced. To reduce the impact of drone vibration on flight safety, measures must be taken to reduce the vibration amplitude. Therefore, it is necessary to design a structure that can reduce vibration during flight to protect the drone battery pack from shock. Thus, there is an urgent need to invent a shockproof and spark-proof buffer bracket for drone battery packs to address the vibration problem during drone flight. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a shockproof and spark-proof buffer bracket for drone battery packs.

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

[0005] This technical solution relates to a shockproof and spark-proof buffer bracket specifically designed for drone battery packs, mainly composed of a support box, a spring assembly, a positioning mechanism, and a linkage device. A first helical spring is fixedly installed on the right end inside the support box, and the left end of the spring is connected to a top plate with a magnet, used to attract and stabilize the battery pack position. An annular positioning ring is located in the middle of the box, with a through groove connecting it to an external arc-shaped folding cover. The surface of the folding cover is designed with guide grooves to facilitate the movement of the linkage components. Multiple sets of composite ribbons are distributed on the left end face of the positioning ring. The ribbons are made of nylon substrate with a rubber layer, combining flexibility and insulation to effectively suppress vibration and spark generation. A support rod structure is set on the side wall of the support box, with a sleeve assembly installed at its top. An internal sliding linkage with a pull rod with a tail fin is connected to the pull rod surface, forming a two-stage buffer system. The folding cover is linked to the pull rod hinge via a groove. When the battery pack is subjected to force, the folding cover deforms, guiding the pull rod to slide along the sleeve axis, achieving multi-dimensional impact absorption in conjunction with the dual-spring system. Furthermore, the entire inner wall of the support box is covered with a rubber buffer layer, which further reduces the risk of mechanical collision through elastic deformation, while also blocking potential electrical sparks generated by contact between metal components. Through the application of composite materials and mechanical linkage design, this structure forms a multi-layered protection system within a limited space, significantly improving the safety and stability of the battery pack under complex operating conditions.

[0006] Compared with the prior art, the beneficial effects of this utility model are:

[0007] This invention utilizes the wind generated during drone flight to provide a certain amount of wind force to the ribbon, and the swaying of the ribbon helps to levitate the battery pack. Compared with current battery pack installations, this further enhances the shock absorption protection of the battery pack. The tail fin, combined with the pull rod, controls the opening and closing of the folding cover using wind force. The top plate, with its suction force on the battery pack and the cushioning effect of the first helical spring, further reduces shock. This invention, by utilizing the wind generated during drone flight and the ribbon design, reduces the rigid connection between the battery pack and the drone, providing levitation support through wind force, thereby reducing shock to the drone battery.

[0012] 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.

[0013] Please see Figure 1-3 This utility model provides a technical solution:

[0014] A shockproof and spark-proof buffer bracket for a drone battery pack includes a support box 3. A first helical spring 1 is fixedly connected to the right end inside the support box 3, acting as a buffer to reduce shock to the drone battery pack. A top plate 2 is fixedly installed at the left end of the first helical spring 1. A positioning ring 4 is fitted inside the middle of the support box 3. Streamers 12 are evenly distributed on the left end face of the positioning ring 4. The streamers 12 help provide support for the drone battery pack, allowing it to be suspended on the surface of the support box 3 and in contact with the positioning ring 4. A folding cover 5 is installed at the corresponding position of ring 4. The function of the folding cover 5 is to collect wind and use the wind force to make the battery float inside the drone. A support rod 9 is fixedly installed on the left side of the folding cover 5 and fixedly installed on the support box 3. A sleeve 8 is fixedly installed at the top of the support rod 9. A pull rod 6 is sleeved inside the sleeve 8. A tail fin 11 is installed at the left end of the pull rod 6. A second helical spring 7 connected to the sleeve 8 is sleeved on the surface of the pull rod 6. When the wind force increases, the pull rod 6 is pulled through the tail fin 11, and the folding cover 5 is unfolded at the same time, so as to collect wind quickly using the folding cover 5.

[0015] Preferably, the top plate 2 is equipped with a magnet, which is used to position the battery pack and, together with the buffer of the first helical spring 1, supports the drone battery pack. The first helical spring 1 provides buffer protection for the drone battery pack.

[0016] Preferably, the positioning ring 4 is a ring structure with a through groove, so that the positioning ring 4 communicates with the folding cover 5. The positioning ring 4 is supported in the support box 3 and is mainly used to connect the ribbon 12. The folding cover 5 is used to collect wind power during flight, which does not require external energy and is more energy-efficient.

[0017] Preferably, the folding cover 5 has an arc-shaped structure, and a groove is provided on the surface of the folding cover 5 for the sliding of the hinge of the pull rod 6. The groove prevents the pull rod 6 from being constrained when it is pulled, and the unfolding of the folding cover 5 can be controlled by wind power. The presence of wind power also further cools the battery when it blows on it, thus protecting the battery.

[0018] Preferably, the ribbon 12 is made of nylon material and has a rubber outer layer. The nylon material makes the ribbon 12 more robust and durable. At the same time, the ribbon 12 is wrapped around the outside of the drone battery. With the help of the wind generated by the drone's flight, the ribbon 12 provides support for the battery, allowing the battery to be suspended and further reducing shock.

[0019] Preferably, the inner wall of the support box 3 is equipped with a buffer pad made of rubber material, which further protects the battery.

[0020] Working principle: The support box 3 is installed inside the drone battery box, and then the battery is placed inside the support box 3 with its end attached to the top plate 2. When the drone is in flight, the folding cover will unfold, blowing air into the support box 3 and causing the ribbon 12 to swing. At the same time, the wind force keeps the battery in a suspended state, preventing violent vibration between the battery and the drone. This effectively protects the battery with double buffer protection. The buffer layer 10 further buffers the impact, improving the shock resistance of the drone battery pack and preventing sparks caused by vibration, thus effectively protecting the drone battery pack.

[0021] It should be noted that the buffer bracket uses the wind generated by the drone's flight to make the ribbon 12 flutter. The ribbon 12 covers the battery pack, allowing the battery pack to be suspended inside the battery box, rather than in direct contact with the battery box. This prevents the drone's own vibration from vibrating the battery during flight, providing shock protection for the battery pack. It transforms the existing fixed battery installation method into a suspended one, supporting the battery while further reducing vibration and improving battery protection.

[0022] Based on this, the bracket can be used in drone flight to effectively reduce the vibration of the drone battery pack, prevent the damage caused by battery pack vibration, and save energy without the need for external resources, making reasonable use of the wind energy generated by the drone itself.

[0023] This invention utilizes the wind generated during drone flight through the folding cover 5 to provide a certain amount of wind force to the ribbon. The swaying of the ribbon helps to levitate the battery pack. Compared with current battery pack installations, this further provides shock protection for the battery pack. The tail fin 11, combined with the lever 6, controls the opening and closing of the folding cover 5 using wind force. The top plate 2, with its suction force on the battery pack and the cushioning of the first helical spring, further provides shock absorption protection for the battery pack. This invention, by utilizing the wind generated during drone flight and the ribbon design, reduces the rigid connection between the battery pack and the drone, providing levitational support through wind force, thereby reducing shock for the drone battery.

[0024] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit the technical solution. Although the applicant has described the utility model in detail with reference to the preferred embodiments, those skilled in the art should understand that any modifications or equivalent substitutions made to the technical solution of this utility model that do not depart from the spirit and scope of this technical solution should be covered within the scope of the claims of this utility model.
