Description

Technical Field

[0001] This invention relates to the field of airbags, and more particularly to an automatic airbag covering device. Background Technology

[0002] Car airbags are an essential component of automobiles. Current airbag bags are primarily made of textiles. During production, they are folded, placed in an airbag box, and finally sealed with an airbag cap. The current airbag caps are also made of textiles with perforations. The cap engages with hooks on the airbag box to seal the opening. The cap has tear strips; when the airbag rapidly inflates and deploys, these tear strips break through, providing safety protection. When the airbag is not in use, the airbag box is sealed by the cap. Currently, this is mainly done manually, but the cap needs to have a relatively tight seal to achieve a secure connection, making manual operation very difficult. Summary of the Invention

[0003] To solve the above problems, this technical solution provides an automatic fabric-wrapping device for air bags.

[0004] To achieve the above objectives, the technical solution is as follows:

[0005] Automatic fabric-fastening equipment for air bags, including

[0006] A securing mechanism used to secure the air bag box;

[0007] A movable mechanism that moves relative to the fixed mechanism;

[0008] A flipping mechanism is attached to the air bag cover on the air supply bag box; the flipping mechanism is mounted on the moving mechanism and moves with the moving mechanism.

[0009] A hooking mechanism is provided on the flipping mechanism and is used to hook the air bag cover of the air bag box; the hooking mechanism includes a positioning post into which a through hole on the air bag cover is inserted.

[0010] A push-in mechanism is provided on the hook-in mechanism;

[0011] The moving mechanism and the flipping mechanism work together to drive the hooking mechanism to flip from the rear side of the air bag box to the front side, so that the positioning post can be connected with the hook on the air bag box, and the pushing mechanism pushes the air bag cover into the hook.

[0012] The automatic air bag covering device described above also includes a lifting mechanism located between the moving mechanism and the flipping mechanism. The lifting mechanism is located on the moving mechanism and moves with the moving mechanism. The lifting mechanism drives the hooking mechanism to move away from the fixed mechanism so as to keep the air bag cover taut during the process of flipping around the air bag box until it covers the air bag box.

[0013] The automatic air bag covering device described above also includes a limiting mechanism provided on the hooking mechanism, which restricts the air bag cover from disengaging from the positioning post during the process of the hooking mechanism flipping from the rear side to the front side of the air bag box.

[0014] As described above, the automatic air bag fastening and wrapping device includes a limiting cylinder, a main rod, a limiting rod disposed on the main rod, and a connecting rod assembly connecting the limiting cylinder and the main rod. The limiting rod is provided with a slot for the positioning post to enter. The limiting cylinder drives the limiting rod to move simultaneously along the depth direction of the slot and the penetration direction of the slot through the connecting rod assembly, so as to disengage from the positioning post.

[0015] As described above, the automatic air bag covering device includes a connecting member on the output end of the limiting cylinder, a fixing member on the limiting cylinder, a first connecting rod with both ends hinged to the middle of the main rod and the fixing member, a second connecting rod with both ends hinged to the rear of the main rod and the rear of the connecting member, and a third connecting rod with both ends hinged to the middle of the first connecting rod and the lower part of the connecting member.

[0016] As described above, the automatic air bag covering device has a U-shaped main body on the positioning post and an abutting part protruding from the main body and used to abut against the end of the hook. The main body and the abutting part together wrap around the periphery of the end of the hook so that the air bag cover can transition from the positioning post to the hook.

[0017] As described above, the automatic air bag covering device includes a pushing mechanism comprising a pushing cylinder and a push plate disposed on the pushing cylinder, a pushing part disposed on the push plate, and a through hole for the positioning post to pass through, wherein the air bag cover passes through the positioning post and is placed on the pushing part.

[0018] As described above, the automatic fabric-wrapping device for air bags includes a moving mechanism comprising a moving slide rail, a moving slider disposed on the moving slide rail, and a moving cylinder for driving the moving slider.

[0019] As described above, the automatic fabric-wrapping device for air bags includes a lifting mechanism comprising a lifting slide rail disposed on the movable slider, a lifting slider disposed on the lifting slide rail, and a lifting cylinder for driving the lifting slider.

[0020] As described above, the automatic air bag covering device includes a rotating motor mounted on the lifting slider and a rotating frame mounted on the output end of the rotating motor. The hooking mechanism and the pushing mechanism are mounted on the rotating frame.

[0021] The beneficial effects of this application are:

[0022] This invention provides an automatic airbag covering device. The airbag cover is pre-attached to the hanging mechanism, allowing the positioning pin to be inserted into the positioning hole on the airbag cover. Then, through the combined assistance of a moving mechanism and a flipping mechanism, the hanging mechanism is flipped from the rear to the front of the airbag box, thus completing the closing action of the airbag cover. Finally, a pushing mechanism pushes the airbag cover from the positioning pin onto the hook that mates with the positioning pin, achieving a fixed connection. This replaces manual operation, saving manpower and improving efficiency. Attached Figure Description

[0029] To make the technical problems solved, the technical solutions, and the beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0030] like Figures 1-5 As shown, the automatic fabric-fastening device for air bags includes...

[0031] The fixing mechanism 1 is used to fix the airbag box 9; the airbag box is generally made of metal such as iron or iron alloy. The fixing mechanism has clamping claws to fix the airbag box.

[0032] The moving mechanism 2 moves relative to the fixed mechanism 1;

[0033] The flipping mechanism 3 is attached to the air bag cover 91 on the air supply bag box; the flipping mechanism 3 is mounted on the moving mechanism 2 and moves with the moving mechanism 2.

[0034] The hooking mechanism 4 is mounted on the flipping mechanism 3 and is used to hook the air bag cover of the air bag box. The hooking mechanism 4 includes a positioning post 41 into which a positioning hole 92 on the air bag cover is inserted. Because the air bag cover needs to remain taut after the hook is inserted into the positioning hole, a relatively large force is required to pull the air bag cover during the hooking process to ensure successful hooking when the positioning hole aligns with the end of the hook. Figure 1 In the diagram, the dotted line represents the airbag cover pre-attached to the positioning post, while the solid line represents the airbag cover attached to the hook. Both lines show the airbag cover after it has been flipped over.

[0035] The push-in mechanism 5 is disposed on the hook-in mechanism 4;

[0036] The moving mechanism 2 and the flipping mechanism 3 cooperate to drive the hooking mechanism 4 to flip from the rear side to the front side of the air bag box so that the positioning post 41 is connected with the hook 93 on the air bag box, and the pushing mechanism 5 pushes the air bag cover into the hook.

[0037] This invention provides an automatic airbag covering device. The airbag cover is pre-attached to the hanging mechanism, so that the positioning pin is inserted into the positioning hole on the airbag cover. Then, with the assistance of the moving mechanism and the flipping mechanism, the hanging mechanism is driven to flip from the rear side to the front side of the airbag box, so that the airbag cover completes the closing action. Finally, through the pushing mechanism, the airbag cover can be pushed from the positioning pin into the hook that is connected to the positioning pin to achieve a fixed connection.

[0038] Furthermore, as a preferred embodiment of this solution, and not a limitation thereof, a lifting mechanism 6 is also included, located between the moving mechanism 2 and the flipping mechanism 3. This lifting mechanism 6 is mounted on the moving mechanism 2 and moves with it. The lifting mechanism 6 drives the hooking mechanism 4 to move away from the fixing mechanism 1, maintaining tension as the airbag cover flips around the airbag box until it covers the airbag box. Because the airbag cover is elastic, and its movement trajectory is not circular when pre-hung on the positioning post compared to when transitioning from the positioning post to the hook, the airbag cover is prone to loosening when the flipping mechanism only performs circular motion, and it is difficult for the airbag cover to smoothly transition onto the hook. Therefore, a lifting mechanism is added to adjust the distance between the airbag cover and the airbag box during the flipping process, maintaining the tension of the airbag cover. During the docking process, the tilt angle of the positioning post relative to the hook is adjusted, allowing the airbag cover to smoothly transition into the hook.

[0039] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, a limiting mechanism 7 is also provided on the hooking mechanism 4, which restricts the air bag cover from disengaging from the positioning post 41 during the process of the hooking mechanism 4 flipping from the rear side to the front side of the air bag box.

[0040] Furthermore, as a preferred embodiment of this solution and not a limitation, the limiting mechanism 7 includes a limiting cylinder 71, a main rod 72, a limiting rod 73 disposed on the main rod 72, and a connecting rod assembly 74 connecting the limiting cylinder 71 and the main rod 72. The limiting rod 73 is provided with a slot 731 for the positioning post 41 to enter. The limiting cylinder 71 drives the limiting rod 73 to move simultaneously along the depth direction and the penetration direction of the slot 731 through the connecting rod assembly 74, so as to disengage from the positioning post 41. The air bag cover is pressed against the push-in part by the limiting rod, so that all positioning holes are in the same horizontal position, so that when the air bag cover is pushed in, each hook can engage with the corresponding positioning hole.

[0041] Furthermore, as a preferred embodiment of this solution and not a limitation, the linkage assembly 74 includes a connector 741 disposed on the output end of the limiting cylinder 71, a fixing member 742 disposed on the limiting cylinder 71, a first connecting rod 743 with both ends hinged to the middle of the main rod 72 and the fixing member 742 respectively, a second connecting rod 744 with both ends hinged to the rear of the main rod 72 and the rear of the connector 741 respectively, and a third connecting rod 745 with both ends hinged to the middle of the first connecting rod 743 and the lower part of the connector 741 respectively. When the limiting rod disengages from the positioning post, since the positioning post is engaged with the hook at this time, if the limiting rod moves along the depth direction of the latch, it will rub against the air bag cover; if it moves along the penetration direction of the latch, it is easy to collide with the hook or the air bag box. Moving along the direction of their convergence can avoid the above situation.

[0042] Furthermore, as a preferred embodiment of this solution and not a limitation, the positioning post 41 is provided with a U-shaped main body 411 and an abutment part 412 protruding from the main body 411 for abutting with the end of the hook. The main body 411 and the abutment part 412 together wrap around the periphery of the end of the hook, so that the air bag cover transitions from the positioning post 41 to the hook. The abutment part abuts with the hook. With the cooperation of the lifting mechanism and the flipping mechanism, the main body uses the position where the ground contact part abuts with the hook as a fulcrum to pry the air bag cover, so that the air bag cover is further tightened, making it easier for the positioning hole to fit into the hook. The abutment part gradually protrudes from the outer periphery of the main body towards the end of the bottom surface of the main body.

[0043] Furthermore, as a preferred embodiment of this solution and not a limitation, the pushing mechanism 5 includes a pushing cylinder 51, a push plate 52 disposed on the pushing cylinder 51, and a pushing part 53 disposed on the push plate 52. The pushing part 53 has a through hole 531 through which the positioning post 41 passes. The air bag cover passes through the positioning post 41 and is placed on the pushing part 53. The push plate has multiple pushing parts that are pushed in simultaneously.

[0044] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the moving mechanism 2 includes a moving slide rail 21, a moving slider 22 disposed on the moving slide rail 21, and a moving cylinder 23 for driving the moving slider 22.

[0045] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the lifting mechanism 6 includes a lifting slide rail 61 disposed on the movable slider 22, a lifting slider 62 disposed on the lifting slide rail 61, and a lifting cylinder 63 for driving the lifting slider 62.

[0046] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the flipping mechanism 3 includes a rotary motor 31 disposed on the lifting slider 62, and a flipping frame 32 disposed on the output end of the rotary motor 31, wherein the hooking mechanism 4 and the pushing mechanism 5 are disposed on the flipping frame 32.

[0047] The above description is only a preferred embodiment of this application and is not intended to limit the scope of implementation of this application. Any other embodiments whose principles and basic structures are the same as or similar to those of this application are within the protection scope of this application.
