Description

Technical Field

[0001] This utility model relates to the technical field of automotive airbag folding machines, specifically a quick-change structure for an automotive airbag folding machine sealing device. Background Technology

[0002] When installing a car airbag, it needs to be folded using a folding machine. In order to prevent the airbag from expanding due to accidental inflation during the folding process, a sealing device is needed to block the air inlet of the airbag. In order to ensure the flexibility of the sealing device during use, the sealing device itself can be disassembled and installed through a quick-change structure.

[0003] During use, the traditional quick-change mechanism may have gaps that cause it to shake, affecting the sealing performance of the sealing device when blocking the air inlet of the airbag. At the same time, the shaking of the sealing device itself will also reduce its applicability when folding the airbag. Utility Model Content

[0004] The purpose of this utility model is to provide a quick-change structure for a sealing device for an automotive airbag folding machine, in order to solve the problem mentioned in the background art that the traditional quick-change mechanism may have gaps during use, causing shaking and affecting the sealing performance of the sealing device when sealing the air inlet of the airbag.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-change structure for a sealing device of an automotive airbag folding machine, comprising a mounting base, a sealing module mounted on the bottom end of the mounting base, and a fixed base sleeved on the outer side of the mounting base; a locking mechanism for fixing the fixed base is provided on the outer side of the mounting base, the locking mechanism including a mating groove, the mating groove being opened at the upper end of the outer side of the mounting base, and a mating block for matching the mating groove being provided on the inner side of the fixed base; and an anti-slip mechanism for increasing friction is sleeved on the outer side of the mounting base.

[0006] Furthermore, connecting plates are installed on the outer side of the fixed base and the upper end of the mounting base, and bolts are threaded at equal angles to the bottom end of the connecting plates.

[0007] Furthermore, a sealing and limiting mechanism is provided on the outer side of the mounting base to prevent the mounting base and the fixed base from shaking during docking. The sealing and limiting mechanism includes a mounting box, which is fitted on the outer side of the mounting base. A second airbag is attached to the bottom of the inside of the mounting box, and a pressing plate is attached to the top of the second airbag. A first airbag is attached to the top of the pressing plate, and the first airbag and the second airbag are connected by a flexible hose.

[0008] Furthermore, the inner side of the mounting box is provided with a sliding groove at an equal angle, and a slider matching the sliding groove is fixedly connected to the outer side of the pressing plate. The pressing plate and the mounting box are slidably connected through the slider and the sliding groove to form a sliding mechanism.

[0009] Furthermore, the top of the first airbag is fitted with the bottom of the connecting plate, and the inner side of the first airbag is fitted with the mounting base.

[0010] Furthermore, the anti-slip mechanism includes an anti-slip layer, which is sleeved on the outside of the mounting base, and wear-resistant layers are evenly distributed on the outside of the anti-slip layer.

[0011] Furthermore, a fixing groove is provided on the outer side of the wear-resistant layer, and the fixing grooves are evenly distributed on the outer side of the wear-resistant layer.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By sliding the docking block to the bottom of the docking groove and twisting the mounting base to deflect its angle, the docking block can be locked inside the docking groove. The docking groove is "L" shaped, and the docking block is locked at the bottom of the docking groove, thus fixing the position of the mounting base and the fixed base. Then, the mounting base and the fixed base are reinforced by bolts and threaded connections between the connecting plate and the mounting box. This effectively avoids the situation where the sealing module becomes loose due to the rapid folding of the airbag after quick installation.

[0014] Furthermore, the bottom of the fixed base will squeeze the top of the first airbag, so that the gas inside the first airbag is delivered to the inside of the second airbag through the hose. This allows the second airbag to fill the gap between the mounting box and the mounting base, thereby fixing the position between the mounting base and the fixed base and preventing the mounting base from shaking after the mounting base and the fixed base are engaged.

[0015] Furthermore, when the pressing plate applies pressure due to the deformation of the first airbag, it will move downwards synchronously. A vertical sliding connection is formed between the pressing plate and the mounting box. The pressing plate drives the slider to slide inside the groove, which makes the movement of the pressing plate smoother and avoids jamming when the pressing plate is pushed downwards, increasing the flexibility during use.

[0016] 2. The anti-slip layer on the outside of the mounting base increases the gripping area, making it easier to hold and tighten during installation. The wear-resistant layer on the outside of the anti-slip layer increases the friction during tightening, preventing the anti-slip layer from slipping off.

[0017] Furthermore, by creating equally spaced fixing grooves on the outer side of the wear-resistant layer, the contact area can be increased, thereby increasing the docking stability between the mounting base and the fixed base. Attached Figure Description

[0025] 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.

[0026] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 5The technical solution shown addresses the problem of inconvenient quick-connection during the installation of the sealing device, which leads to excessive installation time. The quick-change structure for the sealing device of the automotive airbag folding machine discloses a locking mechanism, including a mounting base 2. A sealing module 1 is mounted on the bottom of the mounting base 2, and a fixed base 3 is sleeved on the outer side of the mounting base 2. A locking mechanism for fixing the fixed base 3 is provided on the outer side of the mounting base 2. The locking mechanism includes a mating groove 12, which is located at the upper end of the outer side of the mounting base 2. A mating block 13 matching the mating groove 12 is provided on the inner side of the fixed base 3. Connecting plates 4 are mounted on both the outer side of the fixed base 3 and the upper end of the mounting base 2, and bolts 5 are threaded at equal angles to the bottom of the connecting plates 4.

[0027] In this example, by aligning the mounting base 2 with the fixed base 3, the mating block 13 on the inner side of the fixed base 3 corresponds to the mating groove 12 on the outer side of the mounting base 2. The mating block 13 is slid to the bottom of the mating groove 12 and the mounting base 2 is rotated to deflect its angle, so that the mating block 13 can be engaged inside the mating groove 12. The mating groove 12 is "L" shaped, and the mating block 13 is engaged at the bottom of the mating groove 12, thus fixing the positions of the mounting base 2 and the fixed base 3. Then, the bolt 5 is threadedly connected to the connecting plate 4 and the mounting box 6 to achieve secondary reinforcement between the mounting base 2 and the fixed base 3, effectively preventing the sealing module 1 from loosening due to the rapid folding of the airbag after quick installation.

[0028] Example 2: Figure 1 , Figure 2 , Figure 3 and Figure 6 The technical solution shown addresses the issue of gaps and wobbling that can occur in traditional quick-change mechanisms, affecting the sealing performance of the sealing device when blocking the airbag inlet. The quick-change structure of this automotive airbag folding sealing device discloses a sealing limiting mechanism. A sealing limiting mechanism is fitted onto the outer side of the mounting base 2 to prevent wobbling between the mounting base 2 and the fixed base 3. This sealing limiting mechanism includes a mounting box 6, which is fitted onto the outer side of the mounting base 2. The bottom of the mounting box 6 is fitted with a... The second airbag 9 has a pressing plate 8 attached to its top, and the first airbag 7 is attached to the top of the pressing plate 8. The first airbag 7 and the second airbag 9 are connected by a hose. The inner side of the mounting box 6 has a sliding groove 11 at equal angles, and the outer side of the pressing plate 8 is fixedly connected to a slider 10 that matches the sliding groove 11. The pressing plate 8 and the mounting box 6 are slidably connected by the slider 10 and the sliding groove 11 to form a sliding mechanism. The top of the first airbag 7 is attached to the bottom of the connecting plate 4, and the inner side of the first airbag 7 is attached to the mounting base 2.

[0029] In this example, after the fixed base 3 is fitted onto the outside of the mounting base 2, the bottom end of the fixed base 3 will squeeze the top end of the first airbag 7, thereby allowing the gas inside the first airbag 7 to be delivered to the inside of the second airbag 9 through the hose. This allows the second airbag 9 to fill the gap between the mounting box 6 and the mounting base 2, thus fixing the position between the mounting base 2 and the fixed base 3. This prevents the mounting base 2 from shaking even after it is locked in place. When the pressing plate 8 applies pressure due to the deformation of the first airbag 7, the pressing plate 8 will move downwards synchronously. The pressing plate 8 and the mounting box 6 form a vertical sliding connection. The pressing plate 8 drives the slider 10 to slide inside the slide groove 11, making the movement of the pressing plate 8 smoother and preventing it from getting stuck when pushed downwards, thus increasing the flexibility during use.

[0030] Example 3: Figure 1 , Figure 2 , Figure 4 and Figure 5 The technical solution shown addresses the problem of the quick-change structure of the sealing device for the folding mechanism of an automotive airbag. It discloses an anti-slip mechanism, with the outer side of the mounting base 2 fitted with an anti-slip mechanism to increase friction. The anti-slip mechanism includes an anti-slip layer 14, which is fitted onto the outer side of the mounting base 2. Wear-resistant layers 15 are evenly distributed on the outer side of the anti-slip layer 14. Fixing grooves 16 are formed on the outer side of the wear-resistant layer 15, and these grooves are evenly distributed on the outer side of the wear-resistant layer 15.

[0031] In this example, when docking the mounting base 2 and the fixed base 3, the anti-slip layer 14 on the outer side of the mounting base 2 increases the gripping area, making it easier to hold and tighten. The wear-resistant layer 15 on the outer side of the anti-slip layer 14 increases the friction of the anti-slip layer 14 during tightening, preventing the anti-slip layer 14 from slipping off. At the same time, the fixing grooves 16 evenly spaced on the outer side of the wear-resistant layer 15 increase the contact area, thereby increasing the docking stability between the mounting base 2 and the fixed base 3.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
