Description

Technical Field

[0001] The utility model relates to the technical field of airbag buffering, in particular to an airbag buffering device for aerial delivery. Background Technique

[0002] Aerial delivery by unmanned aerial vehicle (UAV) refers to the operation of dropping goods or materials using a UAV. This technology has a wide range of applications in the fields of military, emergency rescue, material transportation, etc. When using a UAV to drop items, a buffering device is generally set on the items to prevent the items from being damaged due to the large impact force when landing.

[0003] Chinese Patent with the publication number CN221091227U discloses an airbag buffering device for UAV aerial delivery, including a placement box and a buffer box fixed at the bottom. An airbag buffering mechanism including an airbag pad connecting plate, a damping rod and a bottom plate is arranged in the buffer box. During use, the buffering of the item can be achieved by deflating the airbag pad and contracting the damping rod. After use, the airbag pad can be re-inflated, which is convenient for the secondary use of the airbag pad, enabling the buffering structure to be used multiple times and greatly reducing the use cost of the buffering mechanism.

[0004] The above-mentioned prior art solution has the following defects: The airbag pad can be protected from overpressure through an adjustable pressure relief valve, avoiding rupture due to excessive internal pressure after the airbag pad is impacted. However, after the adjustable pressure relief valve protects the airbag pad from overpressure, the gas inside the airbag pad will decrease. If it is to be used for the second time, an air pump needs to be used to inflate it, which makes it difficult for the device to be quickly reused for the second time, thus affecting the efficiency of using aerial delivery in emergency situations. In view of the above situation, technical innovation is carried out on the basis of the existing airbag buffering device for aerial delivery. Content of the Utility Model

[0005] The purpose of the utility model is to provide an airbag buffering device for aerial delivery to solve the problems raised in the above background technique.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0021] Please refer to Figures 1 - 3, An airbag type buffer device for airdrop, which includes an installation box 11. At the bottom of the inner side wall of the installation box 11, there is a pressing plate 2 placed. On the top of the pressing plate 2, there is a first airbag 21 placed. On the top of the first airbag 21, there is a partition plate 22 placed. The top of the partition plate 22 is connected to the second airbag 23. Inflation valves 24 and adjustable pressure relief valves 25 are connected to both the left and right sides of the first airbag 21 and the second airbag 23. Threaded holes are evenly penetrated and opened on the front and back sides of the installation box 11 respectively. Two groups of jacks are evenly opened on the front and back sides of the partition plate 22 respectively. A hand-tightening bolt 16 is screwed in the threaded hole, and the hand-tightening bolt 16 is inserted into the jack. Among them: A set of avoidance grooves are penetrated and opened on both the left and right sides of the installation box 11. The inflation valve 24 is located in the left avoidance groove, and the adjustable pressure relief valve 25 is located in the right avoidance groove. A base 1 is placed at the bottom of the installation box 11. Grooves are evenly opened on the top of the base 1. Damping telescopic rods 111 are fixedly arranged in the grooves. Guide rods 112 are evenly fixedly arranged on the top of the base 1. The tops of the guide rods 112 and the damping telescopic rods 111 both penetrate the bottom of the installation box 11 and are connected to the pressing plate 2. When the device lands during the first airdrop, the impact force generated by the contact between the base 1 and the ground will drive the guide rods 112 and the damping telescopic rods 111 to move upward, and then drive the pressing plate 2 to move upward to squeeze the first airbag 21, and the buffer effect is achieved through the compression of the first airbag 21. When the pressure borne by the first airbag 21 is too large, the adjustable pressure relief valve 25 outside the first airbag 21 is used to deflate and protect it. At this time, the air pressure in the first airbag 21 is not enough to withstand the impact generated by the second airdrop landing. At this time, turn the hand-tightening bolt 16 to separate it from the jack of the partition plate 22. After the second airdrop lands, the generated impact force will squeeze the second airbag 23 upward through the first airbag 21 and the partition plate 22, so that the second airbag 23 provides buffer protection for the second airdrop landing of the device. In this way, the device can quickly perform a second airdrop, thereby improving the airdrop efficiency in an emergency. The first airbag 21 and the second airbag 23 can be inflated through the inflation valves 24 outside them, so as to achieve the effect of recycling.

[0022] A storage box 12 is fixedly arranged on the top of the installation box 11. A box cover 13 is slidably arranged on the top of the storage box 12. A set of buckles 15 are fixedly arranged on the left and right sides of both the storage box 12 and the box cover 13. The length and width dimensions of the base 1 are larger than those of the installation box 11, and the length and width dimensions of the installation box 11 are larger than those of the storage box 12. Two groups of lifting lugs 14 are respectively and evenly fixedly arranged on the front and rear sides of the storage box 12. Emergency supplies can be placed in the storage box 12. The box cover 13 is fixed on the top of the storage box 12 through the buckles 15. The device is suspended at the bottom of the drone through the lifting lugs 14. The length and width dimensions of the whole device gradually expand from top to bottom. Therefore, when the device is airdropped and lands, the base 1 can provide stable support for the device, preventing the device from falling and toppling and damaging the supplies in the storage box 12, thereby ensuring the reliability of the device. The top of the second airbag 23 is attached to the top of the inner side wall of the installation box 11.

[0023] Working principle: Emergency supplies can be placed in the storage box 12. The box cover 13 is fixed on the top of the storage box 12 through the buckles 15. The device is suspended at the bottom of the drone through the lifting lugs 14. The length and width dimensions of the whole device gradually expand from top to bottom. Therefore, when the device is airdropped and lands, the base 1 can provide stable support for the device, preventing the device from falling and toppling and damaging the supplies in the storage box 12, thereby ensuring the reliability of the device. When the device lands for the first time by airdrop, the impact force generated by the contact between the base 1 and the ground will drive the guide rod 112 and the damping telescopic rod 111 to move upward, and then drive the pressing plate 2 to move upward to squeeze the first airbag 21, and the buffer effect is achieved through the compression of the first airbag 21. When the pressure borne by the first airbag 21 is too large, the adjustable pressure relief valve 25 on the outer side of the first airbag 21 is used to deflate and protect it. At this time, the air pressure in the first airbag 21 is not enough to withstand the impact generated by the second airdrop landing. At this time, turn the hand-tightening bolt 16 to separate it from the jack of the partition plate 22. After the device lands for the second time by airdrop, the generated impact force will squeeze the second airbag 23 upward through the first airbag 21 and the partition plate 22, so that the second airbag 23 provides buffer protection for the second airdrop landing of the device, so that the device can be quickly airdropped for the second time, thereby improving the airdrop efficiency in an emergency. The first airbag 21 and the second airbag 23 can be inflated through the inflation valve 24 on their outer sides, so as to achieve the effect of recycling.
