Description

Technical Field

[0001] This utility model relates to the technical field of automobile disassembly, and in particular to an automobile airbag detonation device. Background Technology

[0002] With the rapid growth of car ownership, the dismantling and processing of end-of-life vehicles has become a crucial part of the circular economy. During vehicle dismantling, airbag systems, due to their built-in highly sensitive pyrotechnic components (such as gas generators and igniters), pose an extremely high risk of accidental activation. For example, an accidental airbag explosion caused by improper dismantling operations can result in secondary equipment damage or even personal injury, seriously threatening operational safety and increasing company operating costs.

[0003] Currently, automotive airbags are mainly deployed manually by operators using simple conductive tools. However, this method has the following drawbacks: firstly, because the distance between the operator and the airbag components is relatively close (usually less than 1 meter), the shock wave and fragments generated by the airbag explosion can easily injure the operator; secondly, the triggering device can only process one airbag at a time, resulting in low efficiency. Therefore, to address these shortcomings, the automotive airbag detonation device of this application is proposed. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an automotive airbag detonation device with good operational safety and high processing efficiency.

[0009] Two clamping assemblies are respectively disposed on both sides of the cover plate. Each clamping assembly includes a clamping seat, a spring, a side rod, a clamping strip, a clamping bar, and a clamping element. The clamping seat is disposed on the cover plate. One end of the spring is disposed at the center of the clamping seat. The side rod is adjustablely disposed on one side of the clamping seat. The clamping element is disposed on the other side of the clamping seat. Both ends of the clamping strip are rotatably connected to the side rod and the clamping strip, respectively. When the clamping strip engages with the clamping element, it clamps the airbag onto the clamping seat, thereby compressing the spring.

[0010] Optionally, a pivot is provided at one end of the cover plate, and the pivot passes through the detonation chamber.

[0011] Optionally, a limiting strip is also provided on the inner wall of the detonation chamber, so that when the cover plate closes one of the detonation chambers, the cover plate abuts against the limiting strip.

The two cover-locking drive members are both disposed on the outer side wall of the detonation chamber, and the two cover-locking blocks are respectively disposed on the output shafts of the two cover-locking drive members. The cover-locking drive members are used to drive the cover-locking blocks to extend into the detonation chamber to lock the cover plate.

[0013] Optionally, two sensors are also provided on the outer wall of the detonation box, with the two sensors extending into the two detonation chambers respectively, and both sensors are used to detect the cover plate.

[0019] Compared with the prior art, the present invention has at least the following advantages:

[0020] This utility model discloses an automotive airbag detonation device, comprising a detonation box, a closing assembly, and two clamping assemblies. The detonation box contains two independent detonation chambers. The closing assembly includes a cover plate and a closing drive mechanism. The cover plate is rotatably mounted inside the detonation box, and the closing drive mechanism is located on the outer wall of the detonation box and connected to the cover plate.

[0027] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0028] like Figures 1 to 3 As shown, an automotive airbag detonation device 10 includes a detonation box 100, a closing assembly 200, and two clamping assemblies 300. The detonation box 100 contains two independent detonation chambers 110. The closing assembly 200 includes a cover plate 210 and a closing drive component 220. The cover plate 210 is rotatably disposed within the detonation box 100. The closing drive component 220 is disposed on the outer wall of the detonation box 100 and connected to the cover plate 210. The closing drive component 220 is used to open the other detonation chamber 110 when the cover plate 210 closes one of the detonation chambers 110. The two clamping assemblies 300 are respectively disposed on the cover plate 210. On both sides, the clamping assembly 300 includes a clamping seat 310, a spring 320, a side rod 330, a clamping bar 340, a clamping strip 350, and a clamping component 360. The clamping seat 310 is disposed on the cover plate 210. One end of the spring 320 is disposed at the center of the clamping seat 310. The side rod 330 is adjustablely disposed on one side of the clamping seat 310. The clamping component 360 is disposed on the other side of the clamping seat 310. The two ends of the clamping bar 340 are rotatably connected to the side rod 330 and the clamping strip 350, respectively. When the clamping strip 350 is engaged with the clamping component 360, the clamping bar 340 clamps the airbag onto the clamping seat 310, thereby compressing the spring 320.

[0029] It should be noted that the cover plate 210 is rotated between the two detonation chambers 110 by the cover-closing drive 220, so that the cover plate 210 can open the other detonation chamber 110 while closing one of the detonation chambers 110. Furthermore, a clamping assembly 300 is installed on each of the two sides of the cover plate 210. Specifically, the clamping seat 310 is fixedly installed on the cover plate 210 with screws, one end of the spring 320 is welded and fixed to the clamping seat 310, and the other end of the spring 320 is a free end. The side rod 330 and the clamping component 360 are installed on opposite sides of the clamping seat 310 relative to the spring 320, wherein the height of the side rod 330 relative to the clamping seat 310 is adjustable. The two ends of the clamping strip 340 are rotatably connected to the clamping strip 350 and the side rod 330, respectively. Thus, when the clamp 340 spans above the spring 320 and engages with the locking strip 350 and the locking member 360, the clamp 340 secures the airbag to the locking seat 310 and keeps it fixed. At this time, the airbag compresses the spring 320. Then, when the cover drive 220 rotates the cover plate 210 relative to the detonation box 100, causing the airbag to face the detonation chamber 110, the detonation chamber 110 is also closed by the cover plate 210. By controlling the locking member 360 to disengage from the locking strip 350, the clamp 340 releases the airbag. Under the elastic force of the spring 320, the airbag is forcefully struck against the bottom of the detonation chamber 110, and the airbag is violently detonated by the applied impact force. Meanwhile, the clamping assembly 300 on the other side of the cover plate 210 faces upwards vertically. While the dust settles in the detonation chamber 110 of the previously detonated airbag, another airbag can be secured to the upward-facing clamping assembly 300 on the cover plate 210, and the detonated airbag in the currently open detonation chamber 110 can be removed. This process is repeated continuously. Compared to the manual triggering method in the prior art, the airbag detonation device 10 of this application offers better operational safety and higher processing efficiency.

[0030] like Figure 1 and Figure 2 As shown, in one embodiment, a rotating shaft 230 is provided on one end of the cover plate 210, and the rotating shaft 230 passes through the detonation chamber 110.

[0031] It should be noted that the cover plate 210 is welded and fixed to the outer wall of the rotating shaft 230. The rotating shaft 230 is rotatably mounted inside the detonation box 100 via bearings, allowing the cover plate 210 to rotate stably relative to the detonation box 100. Further, in one embodiment, a pulley is installed on one end of the rotating shaft 230, and the cover-closing drive component 220 is a motor fitted with a belt, with the belt connected to the pulley. Thus, the motor drives the rotating shaft 230 to rotate, thereby causing the cover plate 210 to rotate relative to the detonation box 100.

[0032] like Figure 1 and Figure 2 As shown, in one embodiment, a limiting strip 120 is also provided on the inner side wall of the detonation chamber 110, so that when the cover plate 210 closes one of the detonation chambers 110, the cover plate 210 abuts against the limiting strip 120.

[0033] It should be noted that each of the inner walls of the two detonation chambers 110 is provided with a ring-shaped limiting strip 120. The limiting strip 120 is used to support the cover plate 210 and ensure that the cover plate 210 stably closes the detonation chamber 110. In one embodiment, the limiting strip 120 is welded to the inner wall of the detonation chamber 110.

[0034] like Figure 1 and Figure 2 As shown, in one embodiment, the cover assembly 200 further includes two cover-locking drive members 240 and two cover-locking blocks 250. The two cover-locking drive members 240 are both disposed on the outer side wall of the detonation box 100, and the two cover-locking blocks 250 are respectively disposed on the output shafts of the two cover-locking drive members 240. The cover-locking drive members 240 are used to drive the cover-locking blocks 250 to extend into the detonation chamber 110 to lock the cover plate 210.

[0035] It should be noted that, in order to improve the sealing stability of the cover plate 210, two cover locking drive components 240 are also installed on the detonation box 100. Two cover locking blocks 250 are respectively installed on the output shafts of the two cover locking drive components 240. The cover locking drive components 240 drive the cover locking blocks 250 to extend into the detonation chamber 110, thereby locking the cover plate 210 tightly, improving the stability of the cover plate 210 and preventing the cover plate 210 from opening accidentally. In one embodiment, the cover locking drive component 240 is an electromagnetic engagement switch.

[0036] like Figure 1 and Figure 2 As shown, in one embodiment, two sensors 260 are also provided on the outer wall of the detonation box 100. The two sensors 260 extend into the two detonation chambers 110 respectively, and both sensors 260 are used to detect the cover plate 210.

[0037] It should be noted that the two sensors 260 are installed adjacent to the limit strips 120 in the two detonation chambers 110 respectively. In this way, when the cover plate 210 abuts against the limit strip 120 to close the detonation chamber 110, the sensor 260 detects whether the cover plate 210 abuts against the limit strip 120 to complete the closure, thereby ensuring that the control system can further control the clamping component 360 to release the car airbag.

[0038] like Figures 1 to 3 As shown, in one embodiment, the material holder 310 includes a base plate 311, a shelf 312 and a plurality of support columns 313. Both ends of each support column 313 are connected to the base plate 311 and the shelf 312 respectively. The base plate 311 is disposed on the cover plate 210.

[0039] It should be noted that, supported by the support column 313, the shelf 312 and the bottom plate 311 form a double-layer structure. The side rod 330 and the clamping component 360 are both located on the shelf 312.

[0040] In one embodiment, one end of the spring 320 is disposed on the base plate 311, and the spring 320 passes through the shelf plate 312. Thus, when the clamp 340 clamps and fixes the car airbag to the shelf plate 312, the spring 320 is compressed and located between the shelf plate 312 and the base plate 311.

[0041] In one embodiment, the side rod 330 is screwed onto the shelf 312. Thus, by rotating the side rod 330, its height can be adjusted, allowing the clamp 340 to secure the car airbag, which varies in height depending on the brand. Furthermore, it should be noted that a nut is screwed onto the side rod 330, and the nut abuts against the side shelf 312, so that after the height of the side rod 330 is adjusted, the nut can lock and fix the side rod 330 to the shelf 312.

[0042] like Figure 3 As shown, in one embodiment, the locking strip 350 has a plurality of spaced locking holes 351. Correspondingly, when the height of the side rod 330 is adjusted, in order to make the distance between the two ends of the hoop 340 and the layer plate 312 relatively consistent, a plurality of locking holes 351 are opened on the locking strip 350, so that the material clamping member 360 can pass through one of the locking holes 351 to be clamped and fixed with the locking strip 350.

[0043] like Figure 3 As shown, in one embodiment, the material clamping component 360 includes a material clamping drive unit 361 and a material clamping block 362. The material clamping drive unit 361 is disposed on the shelf 312, and the material clamping block 362 is slidably disposed on the shelf 312. The material clamping block 362 is connected to the output shaft of the material clamping drive unit 361. The material clamping drive unit 361 is used to drive the material clamping block 362 to engage or disengage from one of the clamping holes 351.

[0044] It should be noted that the material-clamping drive unit 361 drives the material-clamping block 362 to extend or retract from some parts of the shelf plate 312, thereby allowing the material-clamping block 362 to engage with or disengage from the clip 350. In one embodiment, the material-clamping drive unit 361 is also an electromagnetic engagement switch, so that when the material-clamping block 362 extends, it can be inserted into one of the clip holes 351, thereby allowing the material-clamping block 362 to engage and fix with the clip 350.

[0045] like Figure 1 As shown, in one embodiment, the bottom of the detonation box 100 is provided with several rollers 400. In this way, the rollers 400 facilitate transfer.

[0046] In one embodiment, both the clamp strip 340 and the retaining strip 350 are thin-patch structures, so the clamp strip 340 and the retaining strip 350 can be bent and deformed at will, thereby better clamping the car airbag.

[0047] Furthermore, it should be noted that the automotive airbag detonation device 10 of this application is used to detonate and scrap the airbag component that is mounted together with the horn on the steering wheel of the vehicle.

[0048] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. Unless otherwise specifically defined, the installation / fixing / setting mentioned in this utility model can be understood as including, but not limited to, locking and fixing with screws / bolts, welding, or bonding with adhesives, wherein the adhesives used can be commercially available finished products. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
