Description

Technical Field

[0001] This utility model belongs to the field of drone airdrop technology, specifically relating to an airbag-buffered drone delivery bin. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment and their own program control devices. They are widely used in the field of safety rescue. UAVs can accurately deliver supplies to the required areas, especially in areas with complex terrain, where they perform even better.

[0003] Generally speaking, when using drones to deliver supplies, the supplies are placed in a matching delivery bin or container. The container normally serves the purpose of storage and transportation, and provides protection during airdrop. However, the delivery container will be subject to a large impact upon landing. Although it protects the supplies inside, it is still easy to damage the container itself. Therefore, a drone delivery bin with good protection is needed. Utility Model Content

[0004] In view of this, in order to solve the problems mentioned in the background art, the purpose of this utility model is to provide an airbag-buffered drone delivery bin.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An airbag-cushioned drone delivery bay includes: The main body has an upwardly recessed bottom forming an installation cavity; An airbag assembly, including an airbag and a receiving device capable of receiving the compressed airbag within the mounting cavity; A buffer assembly is fixed within the mounting cavity and at least partially protrudes from the body. A trigger component is fixed inside the mounting cavity. When the buffering process of the buffer component exceeds a threshold, the trigger component triggers the airbag to inflate. After inflation, the airbag protrudes from the body and causes the receiving device to be unlocked.

[0006] Preferably, the airbag assembly has a ring-shaped structure so that it circumferentially surrounds the buffer assembly and the trigger assembly.

[0007] Preferably, the receiving device includes a fixed magnetic base and a flexible magnetic strip that can attract each other. Both the fixed magnetic base and the flexible magnetic strip are connected to the surface of the airbag, and the fixed magnetic base is fixedly installed in the mounting cavity. When the receiving device is in the unlocked state, the fixed magnetic base and the flexible magnetic strip are separated.

[0008] Preferably, a receiving cavity is reserved between the fixed magnetic base and the inner wall of the mounting cavity, and when the flexible magnetic strip is magnetically locked onto the fixed magnetic base, the compressed airbag is received in the receiving cavity.

[0009] Preferably, the buffer assembly includes a fixed base and a first buffer spring connected to the fixed base.

[0010] Preferably, the buffer assembly further includes a contact that slides through the fixed base, and the first buffer spring connects the contact to the fixed base.

[0011] Preferably, the buffer assembly further includes a second buffer spring connected inside the fixed base, the contact and the second buffer spring are coaxially assembled, and a buffer gap is reserved between them.

[0012] Preferably, the triggering assembly includes a trigger switch, a solenoid valve, and a gas cylinder. The trigger switch is mounted on the mounting base, and the solenoid valve connects the gas cylinder and the air bag in response to the closing of the trigger switch.

[0013] Preferably, the contact head has an axial guide groove, a first inclined rod is fixed in the axial guide groove, and a second inclined rod adapted to the first inclined rod is damped and slidably mounted on the fixed seat. The trigger switch responds to the movement of the second inclined rod to open or close.

[0014] Preferably, a reset push rod extending from the axial guide groove to the outside of the fixed seat is fixed on the second inclined rod.

[0015] Compared with the prior art, this utility model has the following advantages: (1) In this utility model, the buffer component is used to buffer the impact force received by the delivery chamber body when it lands, and at the same time, the trigger component is used to change the airbag from a compressed state to an inflated state, so as to instantly complete the further buffer protection of the delivery chamber body after landing and avoid damage to the delivery chamber; in addition, the deflated airbag can be compressed and stored in the mounting cavity at the bottom of the delivery chamber body through the receiving device, so as to facilitate the reuse of the entire airbag component and the delivery chamber.

[0016] (2) In this utility model, the housing device includes a fixed magnetic base and a flexible magnetic strip that can attract each other. The structure is simple, and the deformable characteristics of the flexible magnetic strip can flexibly adapt to the compression and inflation of the airbag.

[0017] (3) In this utility model, the buffer component includes a multi-level buffer structure and a slant structure that can cause the trigger switch to open or close. In this way, while realizing the linkage between the buffer component and the trigger component, it can also effectively prevent the trigger switch from being crushed when the buffer component is subjected to excessive force.

[0020] like Figure 1 and Figure 3As shown, the present invention provides an airbag-cushioned drone delivery container, comprising a main body 1, an airbag assembly 2, a cushioning assembly 3, and a triggering assembly 4. Specifically, the main body 1 has a box-like structure, and the delivery materials are placed inside the main body 1; the bottom of the main body 1 is recessed to form an installation cavity, and the airbag assembly 2, the cushioning assembly 3, and the triggering assembly 4 are all adapted to be installed in the installation cavity, thereby automatically cushioning and protecting the main body 1 after it is released and touches the ground, preventing damage.

[0021] Example: In the initial state, the airbag 21 in the airbag assembly 2 presents as follows Figure 1 and Figure 2 The airbag 21 is compressed and recessed inside the mounting cavity. After the delivery chamber of this invention is deployed by a drone, the main body 1 falls freely and touches the ground. Upon impact, the buffer component 3 cushions the landing of the main body 1. Simultaneously, when the cushioning process of the buffer component 3 exceeds a threshold, the trigger component 4 is activated, thereby causing the airbag 21 to instantly change from a compressed state to a compressed state. Figure 3 and Figure 4 As shown in the inflated state, the airbag 21 protrudes from the body 1 after inflation, thereby providing further protection for the overall delivery compartment body 1.

[0022] Continue to refer to Figure 2 and Figure 4 As shown, the airbag assembly 2 further includes a receiving device 22 capable of housing the deflated, compressed airbag 21 within the mounting cavity. The receiving device 22 includes a fixed magnetic base 221 and a flexible magnetic strip 222 that attract each other. Both the fixed magnetic base 221 and the flexible magnetic strip 222 are connected to the surface of the airbag 21, and the fixed magnetic base 221 is fixedly installed within the mounting cavity. Specifically, a receiving cavity is reserved between the fixed magnetic base 221 and the inner wall of the mounting cavity. When the flexible magnetic strip 222 is magnetically locked onto the fixed magnetic base 221, the compressed airbag 21 is housed within the receiving cavity; after the airbag 21 inflates and protrudes from the body 1, when the receiving device 22 is in an unlocked state, the fixed magnetic base 221 separates from the flexible magnetic strip 222.

[0023] For example, combined Figure 2 and Figure 4As shown, the connection point between the fixed magnetic base 221 and the airbag 21 is used as a distinguishing point. The two sides of the distinguishing point are considered as the inner and outer sides of the airbag 21, respectively. The flexible magnetic strip 222 is fixed to the outer side of the airbag 21, and the inner part of the airbag 21 connected between the flexible magnetic strip 222 and the fixed magnetic base 221 is larger than the outer part of the airbag 21. That is, the fixed magnetic base 221 and the flexible magnetic strip 222 are asymmetrically arranged relative to the airbag 21. Based on this, when accommodating the compressed airbag 21, the inner part of the airbag 21 is folded into... Figure 2 In the indicated state, the flexible magnetic strip 222 is then magnetically locked onto the fixed magnetic base 221, and the outer part of the airbag 21 is used to wrap the inner part of the folded airbag 21, thereby ensuring that the entire airbag 21 can be compressed and housed inside the receiving cavity. When the airbag 21 is inflated, the expansion of the airbag 21 overcomes the magnetic attraction between the fixed magnetic base 221 and the flexible magnetic strip 222, thereby making the fixed magnetic base 221 and the flexible magnetic strip 222 form a Figure 4 The separation state is shown. The flexible magnetic strip 222 has flexible deformation characteristics, enabling it to flexibly adapt to the compression and inflation of the airbag 21.

[0024] It is worth noting that the airbag assembly 2 is in the form of a ring structure, so that the airbag assembly 2 surrounds the buffer assembly 3 and the trigger assembly 4 in a circumferential manner, thereby ensuring the protective effect of the airbag 21 on the body 1, the buffer assembly 3 and the trigger assembly 4 after inflation.

[0025] Continue to refer to Figure 5 As shown, the buffer assembly 3 includes a fixed base 31, a first buffer spring 32, a contact 33, and a second buffer spring 34. Specifically, the fixed base 31 is directly fixed inside the mounting cavity by bolts, and a cavity is provided inside the fixed base 31. The second buffer spring 34 is fixed inside the cavity. The contact 33 slides through the bottom of the fixed base 31, so that the upper end of the contact 33 extends into the cavity and forms a buffer gap with the second buffer spring 34. The lower end of the contact 33 extends below the fixed base 31, and the first buffer spring 32 is connected between the lower end of the contact 33 and the bottom of the fixed base 31. It is worth noting that the buffer assembly 3 is correspondingly arranged at the four corners of the body 1 to form a balanced buffer for the body 1. The contact 33 and the second buffer spring 34 are coaxially assembled, and the lower end of the contact 33 extends to the outside of the body 1.

[0026] For example, when the body 1 falls to the ground, the lower end of the contact 33 will first contact the ground, and the contact 33 will abut against the ground, causing the contact 33 to compress the first buffer spring 32, which is the first-level buffer; when the impact force of the body 1 landing is large, the upper end of the contact 33 will move to abut against the second buffer spring 34, and compress the second buffer spring 34, which is the second-level buffer; in this way, the impact force received by the body 1 when landing can be effectively reduced.

[0027] Continue to refer to Figure 1 and Figure 3 As shown, the triggering component 4 includes a trigger switch 41, a solenoid valve 42, and a gas cylinder 43. The trigger switch 41 is mounted on the fixed base 31. The solenoid valve 42, in response to the closing of the trigger switch 41, connects the gas cylinder 43 and the air bag 21. Specifically, the triggering component 4 also includes a power module (not shown in the figure). The solenoid valve 42 is electrically connected to the power module through the trigger switch 41, so that when the trigger switch 41 is closed, the solenoid valve 42 connects the gas cylinder 43 and the air bag 21. The gas cylinder 43 contains helium or carbon dioxide. Regarding the connection position between the solenoid valve 42 and the air bag 21, an inflation port is provided at the position where the air bag 21 connects to the fixed magnetic base 221. In addition, the air bag 21 is also provided with a deflation valve (not shown in the figure) that is not obstructed by the fixed magnetic base 221 and the flexible magnetic strip 222, so as to facilitate the deflation and compression operation of the inflated air bag 21.

[0028] For example, combined Figure 5 and Figure 6 As shown, the contact 33 has an axial guide groove 331, and a first inclined rod 332 is fixed inside the axial guide groove 331. A second inclined rod 333, adapted to the first inclined rod 332, is damped and slidably mounted on the fixing base 31. The trigger switch 41 responds to the movement of the second inclined rod 333 by opening or closing. Therefore, when the contact 33 abuts against the ground and moves into the cavity, it drives the first inclined rod 332 to move synchronously. Figure 5 The orientation shown indicates that the contact 33 and the first inclined rod 332 move upwards. The first inclined rod 332, through its mating inclined surface, pushes the second inclined rod 333 to the right, causing the second inclined rod 333 to act on the trigger switch 41 fixed to the right side of the fixed base 31, thereby driving the trigger switch 41 to close. The damped sliding of the second inclined rod 333 ensures that it will not move erroneously when no external force is applied, thus guaranteeing the accurate triggering of the trigger assembly 4.

[0029] It is worth noting that a reset push rod 334 extending from the axial guide groove 331 to the outside of the fixed seat 31 is also fixed on the second inclined rod 333. In this way, the second inclined rod 333 can be reset and the trigger switch 41 can be disconnected by manually pushing the reset push rod 334, thereby ensuring that the overall buffer assembly 3 and the trigger assembly 4 can be adapted to the airbag assembly 2 for repeated use and reducing the cost of using the delivery chamber.
