Description

Technical Field

[0001] This utility model relates to the field of airbag technology, and in particular to an airbag for maintaining the parallel propulsion of a passive component. Background Technology

[0002] Airbags are an important component of a vehicle's passive safety system. They are generally used in conjunction with an inflation device. Specifically, one end of the airbag is fixed to an inflation device, and the other end expands continuously as the inflation device inflates, providing passive protection for the occupant.

[0003] To facilitate transportation, large items such as drones are often housed in small shipping containers. During loading and unloading, tools are needed to insert or remove them from these confined spaces. Current methods often result in collisions between the drones and the tools, causing scratches and damage. Therefore, the applicant proposes using inflated airbags to push the drones into or out of these confined spaces. These airbags effectively prevent scratches and damage to the drones. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model proposes an airbag for keeping the passive component moving in parallel, so as to reduce the probability of the passive component being scratched or bumped during the propulsion process.

[0005] This utility model is achieved through the following technical solution: an airbag for maintaining the parallel propulsion of a passive component, comprising a bag body, the bag body comprising a first piece and a second piece, the second piece comprising a square body and four extended pieces extending outward from the four sides of the square body, the first piece being disposed opposite to the square body, the extended pieces being bent relative to the square body and then sewn together with the first piece, adjacent extended pieces also being sewn together, a sealed inflation cavity being formed between the first piece and the second piece, an inflation device being provided on the body, the inflation device being able to inflate the inflation cavity to make it expand, the sewn joint between the first piece and the extended pieces forming a pushing surface, used to push the passive component to move parallel as the inflation cavity expands.

[0006] As a further improved technical solution, the extended sheet is bent at 90° relative to the square body.

[0007] As a further improved technical solution, a plurality of first pull straps are provided between the extended sheet and the square body.

[0008] As a further improved technical solution, multiple second pull straps are provided between the oppositely arranged extension pieces.

[0009] As a further improved technical solution, a first positioning protrusion is provided on the periphery of the first piece, and a second positioning protrusion is provided on the end of the extension piece away from the square body. When the first piece and the second piece are sewn together, the first positioning protrusion and the second positioning protrusion are aligned.

[0010] As a further improved technical solution, silicone is applied to the seam between the first sheet and the second sheet, as well as the seam between adjacent extension sheets.

[0011] As a further improved technical solution, the square body is provided with a through hole, and the inflation device is inserted into the through hole.

[0012] As a further improved technical solution, the square body is provided with reinforcing plates on both opposite end faces, and the inflation device is inserted through the square body and the reinforcing plates.

[0013] As a further improved technical solution, silicone is also applied between the reinforcing sheet and the square body.

[0014] The airbag provided by this utility model gradually expands under the inflation device. During the expansion process, the pushing surface pushes the passive component to move in parallel. The pushing surface comes into contact with the passive component, which can reduce the occurrence of scratches or bumps on the passive component and can play a good protective role for the passive component.

[0021] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 6 As shown, this utility model discloses an airbag for maintaining the parallel propulsion of a passive component, comprising a bag body, the bag body including a first piece 1 and a second piece 2, the second piece 2 including a square body 3 and four extension pieces 4 extending outward from the four sides of the square body 3 respectively, the first piece 1 and the square body 3 are arranged opposite to each other, the extension pieces 4 are bent relative to the square body 3 and then sewn together with the first piece 1, and adjacent extension pieces 4 are also sewn together, thus forming a sealed inflation cavity 5 between the first piece 1 and the second piece 2, an inflation device is provided on the square body 3, the inflation device can inflate the inflation cavity 5 to make it expand, the sewn joint between the first piece 1 and the extension pieces 4 forms a pushing surface 6, which is used to push the passive component to move parallel as the inflation cavity 5 expands.

[0024] The pushing surface 6 is used to contact the passive component. Due to the setting of the first piece 1, the pushing surface 6 can fit and abut against the passive component. The pushing surface 6 and the square body 3 can be rectangular or square. Their size is mainly set according to the contact size with the passive component. When the pushing surface 6 is not in contact with the passive component, the inflation device inflates it. At this time, the shape and area of ​​the pushing surface 6 are consistent with the square body 3. The shape of the first piece 1 is not limited in any way. It can be rectangular, square, circular, etc.

[0025] The inflation device is the same as existing technology and will not be described in detail here. When the inflation device is inflated, the inflation chamber 5 expands, the extension plate 4 extends, and the pushing surface 6 pushes the passive component to move in parallel. In this embodiment, the extension plate 4 and the square body 3 are bent at 90°, that is, the extension plate 4 extends perpendicularly from the four sides of the square body 3 towards the first plate 1, so that the inflation chamber 5 forms a cube after being inflated.

[0026] To maintain the extension direction of extension sheet 4 during inflation, please refer to... Figure 2 As shown, multiple first pull straps 7 are provided between the extension sheet 4 and the square body 3. After inflation, the first pull straps 7 are arranged obliquely. Please refer to... Figure 3As shown, multiple second pull straps 8 are provided between the oppositely positioned extension pieces 4. After inflation, the second pull straps 8 are parallel to the square body 3, that is, the second pull straps 8 are vertically positioned. Please refer to... Figure 4 As shown, both the first pull strap 7 and the second pull strap 8 are disposed within the inflation chamber 5. The first pull strap 7 and the second pull strap 8 cause the extension plate 4 to extend towards the first plate 1, allowing the force of the gas filling the inflation chamber 5 to act on the pushing surface 6, thereby pushing the passive component.

[0027] In this embodiment, a first positioning protrusion 9 is provided on the periphery of the first piece 1, and a second positioning protrusion 10 is provided on the end of the extension piece 4 opposite to the square body 3. When the first piece 1 and the second piece 2 are sewn together, the first positioning protrusion 9 and the second positioning protrusion 10 are aligned. The seam between the first piece 1 and the second piece 2 is located within the outer periphery of the first piece 1, and there is a certain distance between the seam and the end of the extension piece 4 opposite to the square body 3, that is, the area of ​​the pushing surface 6 is smaller than the area of ​​the first piece 1. Please refer to [reference needed]. Figure 5 The above, Figure 5 The dotted line in the figure represents the seam where the extended piece 4 and the first piece 1 are stitched together on the first piece 1.

[0028] To better achieve a tighter seal in the inflation chamber 5 and improve the heat resistance of the bag, silicone is applied to the seams between the first sheet 1 and the second sheet 2, as well as the seams between adjacent extension sheets 4. Silicone is first applied to the first sheet 1 and the second sheet 2, and then the sheets are sewn together.

[0029] The square body 3 has a through hole 11, and the inflation device passes through the through hole 11. In this embodiment, at least one layer of reinforcing sheet 12 is provided on each of the opposite end faces of the square body 3. The number of reinforcing sheet 12 layers is not limited, but generally, two layers of reinforcing sheet 12 are preferred on one end face of the square body 3. The inflation device passes through the square body 3 and the reinforcing sheet 12, that is, the through hole 11 passes through the reinforcing sheet 12 and the square body 3 respectively. The reinforcing sheet 12 provides a fixing effect for the inflation device.

[0030] In this embodiment, silicone is applied between the reinforcing sheet 12 and the square body 3, as well as between adjacent reinforcing sheets 12, and then the reinforcing sheet 12 is sewn and fixed to the square body 1.

[0031] When the passive component needs to be pushed into a narrow container, it is first positioned on a platform flush with the container. Then, a tool with an airbag is used to push the passive component. Specifically, the pushing surface 6 contacts the passive component, and the inflation device inflates it, causing the extension plate 4 to expand. During expansion, the pushing surface 6 pushes the passive component to move parallel. The square body 3 can be fixed to the tool; alternatively, the tool can be mounted on a hydraulic cylinder, pneumatic cylinder, or other similar component. The airbag can also be pushed by a hydraulic cylinder, pneumatic cylinder, or other driving mechanism, simultaneously pushing the passive component into the container. When the passive component needs to be pushed out of a narrow container, the airbag is positioned on the side wall of the container. Specifically, the square body 3 is fixed to the side wall of the container, the pushing surface 6 contacts the passive component, the inflation device inflates it, and the extension plate 4 expands. During expansion, the pushing surface 6 pushes the passive component out of the container and onto a support platform flush with the container. By designing the first piece 1, the likelihood of the passive component being scratched or damaged by it can be reduced. Furthermore, the pushing surface 6 can be adapted to and abut against the passive component, allowing it to be pushed forward or backward in parallel, further protecting it. We conducted multiple tests on agricultural drones, setting the length of the square body 3 and the pushing surface to approximately 3 meters. Then, by filling the drone with gas to push a 150 kg drone, we achieved parallel propulsion without scratches or damage.

[0032] This utility model has been described through several specific embodiments. Those skilled in the art should understand that various modifications and equivalent substitutions can be made to this utility model without departing from its scope. Furthermore, various modifications can be made to this utility model for specific situations or circumstances without departing from its scope. Therefore, this utility model is not limited to the specific embodiments disclosed, but should include all embodiments falling within the scope of the claims of this utility model.
