Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, and in particular to an adjustable universal automobile side curtain air generator bracket. Background Technology

[0002] Side curtain airbags, as a core component of a vehicle's passive safety system, are typically installed along the roof longitudinal beams from the A-pillar to the C-pillar. In the event of a side collision, they deploy instantly to cover the side window area, buffering the direct impact between the occupant and the vehicle structure, reducing the risk of head injury by more than 40%. The side curtain airbag generator bracket, as a crucial carrier connecting the generator to the side panel of the vehicle, directly determines the airbag's deployment posture through its installation precision and compatibility.

[0003] In the existing technology, traditional track fastener inspection brackets are mostly customized fixed structures, which need to be designed separately according to the track gauge and fastener type. This has certain problems. For different specifications of tracks, multiple brackets need to be stocked, which increases inventory costs. When changing track inspection scenarios, the entire bracket needs to be replaced, which increases replacement time and is inefficient. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an adjustable universal automotive side curtain air generator bracket.

[0005] This utility model is achieved using the following technical solution: an adjustable universal car side curtain airbag generator bracket, including an airbag generator, a connecting groove is provided on the outer wall of the airbag generator, a metal connecting strip is disposed in contact with the inner wall of the connecting groove, a metal connecting block is fixedly connected to the back of the metal connecting strip, a fixing block shell is fixedly connected to the back of the metal connecting block, a connecting shaft is fixedly connected to the end of the metal connecting strip away from the metal connecting block, a connecting bolt is threadedly connected to the inner wall of the connecting shaft, the connecting bolt extends through the inner wall of the connecting shaft, a connecting shaft is threadedly connected to the outer wall of the connecting bolt, a limiting groove is provided on the inner wall of the fixing block shell, a metal connecting plate is slidably connected to the inner wall of the limiting groove, and a connecting bolt is threadedly connected to the inner wall of the metal connecting plate.

[0006] As a further improvement to the above solution, the back of the second connecting shaft is fixedly connected to the front of the metal connecting block, and the second connecting bolt penetrates the inner wall of the metal connecting plate and extends therethrough.

[0007] As a further improvement to the above solution, two connecting slots are provided, and the two connecting slots are symmetrically arranged around the center of the fixing block shell. Two metal connecting blocks are provided, and the two metal connecting plates are provided.

[0008] Through the above technical solution, the air curtain generator, as a key functional component of the detection device, has two connecting grooves on its outer wall that are symmetrically arranged around the center of the fixed block shell. These grooves provide dedicated assembly slots for the metal connecting strips, ensuring precise connection positions and balanced force distribution. The fixed block shell, as the main load-bearing structure of the device, has two metal connecting blocks fixed to its front that are symmetrically arranged around the center of the fixed block shell. These blocks provide rigid support for the subsequent installation of the connecting shaft and connecting shaft two.

[0009] As a further improvement to the above solution, a second limiting groove is provided on the inner wall of the fixed block housing, and a bidirectional threaded rod is rotatably connected to the inner wall of the fixed block housing, with an adjustment groove provided on the right side of the bidirectional threaded rod.

[0010] As a further improvement to the above solution, the outer wall of the bidirectional threaded rod is threadedly connected to a threaded slider, and the bottom of the second limiting groove is provided with a guide groove, and the outer wall of the threaded slider is slidably connected to the inner wall of the guide groove.

[0011] As a further improvement to the above solution, two threaded sliders are provided, and the two threaded sliders are arranged symmetrically about the center of the fixed block housing.

[0012] As a further improvement to the above solution, the surface of the threaded slider is fixedly connected with a positioning buckle, and two positioning buckles are provided.

[0013] Through the above technical solution, the limiting groove 2 opened on the inner wall of the fixed block shell and the guide groove opened at the bottom form a double track limiting structure. The limiting groove 2 restricts the vertical displacement of the threaded slider, and the guide groove restricts its lateral displacement, providing a stable sliding path for the threaded slider.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention uses an air curtain generator as a key functional component of the detection device. Two connecting grooves symmetrically arranged around the center of the fixed block housing on its outer wall provide dedicated assembly slots for the metal connecting strip, ensuring precise connection and balanced force. The fixed block housing serves as the main load-bearing structure of the device. Two metal connecting blocks symmetrically arranged around the center of the fixed block housing, fixed to its front, provide rigid support for the subsequent installation of the connecting shaft and connecting shaft two, preventing structural misalignment from affecting detection accuracy after assembly. The end of the metal connecting strip furthest from the metal connecting block is inserted into the connecting groove on the outer wall of the air curtain generator, ensuring tight contact between the outer wall of the metal connecting strip and the inner wall of the connecting groove. The symmetrically arranged connecting grooves, in conjunction with the metal connecting strip, restrict the horizontal displacement of the air curtain generator, preventing lateral shift. Simultaneously, the back of the metal connecting strip is fixedly connected to the front of the metal connecting block, forming the initial connection path of the fixed block housing, metal connecting block, metal connecting strip, and air curtain generator, laying the foundation for subsequent bolt tightening. The end of the metal connecting strip furthest from the metal connecting block is fixedly connected to the connecting shaft, and the back of the connecting shaft two is fixedly connected to the front of the metal connecting block, with the axes of the connecting shaft and connecting shaft two aligned. Insert connecting bolt one from the end of connecting shaft away from connecting shaft two, so that connecting bolt one penetrates the inner wall of connecting shaft two and extends to the inner wall of connecting shaft two. The connecting shaft and connecting shaft two are rigidly fixed through threaded engagement. This structure further strengthens the connection strength between the metal connecting strip and the metal connecting block, preventing the connection from loosening due to vibration of the air curtain generator and ensuring the stability of the device position during testing. A limiting groove one opened on the inner wall of the fixing block shell provides a sliding track for the two metal connecting plates. The inner wall of the metal connecting plate slides along the inner wall of the limiting groove one, allowing flexible movement along the length of the limiting groove one, enabling fine-tuning of the installation position of the fixing block shell. After the metal connecting plate slides to the target installation position, connecting bolt two penetrates the inner wall of the metal connecting plate and extends to the external installation structure, such as the track side frame or sleeper fixing seat. This adjustment function can adapt to the installation spacing of fasteners of different specifications, solving the compatibility problem of traditional fixed brackets that are used for only one type.

[0016] This utility model uses a limiting groove two opened on the inner wall of the fixed block shell to form a double track limiting structure with a guide groove opened at the bottom. The limiting groove two restricts the vertical displacement of the threaded slider, and the guide groove restricts its lateral displacement, providing a stable sliding path for the threaded slider. The bidirectional threaded rod, rotatably connected to the inner wall of the fixed block housing, has two sections of threads with opposite directions machined on its outer wall. An adjustment slot on the right side allows for the insertion of an adjustment tool, providing an operating interface for manual or mechanical rotation of the bidirectional threaded rod. This is the core power input for the entire adjustment assembly. Two threaded sliders, symmetrically arranged around the center of the fixed block housing, have their inner walls meshing with the opposing threads on the outer wall of the bidirectional threaded rod. When the bidirectional threaded rod is rotated by inserting an adjustment tool into the adjustment slot, the symmetrically arranged threaded sliders will move synchronously inward or outward. Throughout the process, the outer wall of the threaded sliders remains in close contact with the inner wall of the guide groove. Combined with the vertical limiting of the second limiting groove, this ensures that the sliders move synchronously in the opposite direction only in the horizontal direction, without tilting or jamming. Two positioning buckles fixed to the surface of the threaded sliders move synchronously in the opposite direction as the threaded sliders slide. The adjustable range of the bidirectional adjustment assembly, combined with the sliding adjustment of the original metal connecting plate, allows the device to adapt to different specifications of track fasteners.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] Example:

[0027] Please combine Figure 1-6 This embodiment of an adjustable universal car side curtain airbag generator bracket includes an airbag generator 1. The outer wall of the airbag generator 1 has a connecting groove 2. The inner wall of the connecting groove 2 is contacted by a metal connecting strip 3. A metal connecting block 4 is fixedly connected to the back of the metal connecting strip 3. A fixing block housing 5 is fixedly connected to the back of the metal connecting block 4. A connecting shaft 6 is fixedly connected to the end of the metal connecting strip 3 away from the metal connecting block 4. A connecting bolt 7 is threadedly connected to the inner wall of the connecting shaft 6. The connecting bolt 7 passes through the inner wall of the connecting shaft 6 and extends. A connecting shaft 8 is threadedly connected to the outer wall of the connecting bolt 7. A limiting groove 9 is provided on the inner wall of the fixing block housing 5. A metal connecting plate 10 is slidably connected to the inner wall of the limiting groove 9. A connecting bolt 11 is threadedly connected to the inner wall of the metal connecting plate 10.

[0028] The back of the connecting shaft 2 8 is fixedly connected to the front of the metal connecting block 4, and the connecting bolt 2 11 penetrates the inner wall of the metal connecting plate 10 and extends thereafter.

[0029] Two connecting grooves 2 are provided, symmetrically arranged around the center of the fixing block housing 5. Two metal connecting blocks 4 are provided, symmetrically arranged around the center of the fixing block housing 5. Two metal connecting plates 10 are provided. A connecting shaft 6 is fixedly connected to the end of the metal connecting strip 3 away from the metal connecting block 4. The back of the connecting shaft 2 8 is fixedly connected to the front of the metal connecting block 4, and the axes of the connecting shaft 6 and the connecting shaft 2 8 are aligned. A connecting bolt 1 7 is inserted from the end of the connecting shaft 6 away from the connecting shaft 2 8, so that the connecting bolt 1 7 penetrates the inner wall of the connecting shaft 6 and extends to the inner wall of the connecting shaft 2 8, and the connecting shaft 6 and the connecting shaft 2 8 are rigidly fixed by thread engagement.

[0030] The inner wall of the fixed block housing 5 is provided with a limiting slide groove 12, and the inner wall of the fixed block housing 5 is rotatably connected with a bidirectional threaded rod 13. An adjustment groove 14 is provided on the right side of the bidirectional threaded rod 13.

[0031] The outer wall of the bidirectional threaded rod 13 is threadedly connected to a threaded slider 15. The bottom of the limiting slide groove 12 is provided with a guide groove 16, and the outer wall of the threaded slider 15 is slidably connected to the inner wall of the guide groove 16.

[0032] There are two threaded sliders 15, which are arranged symmetrically with respect to the center of the fixed block housing 5.

[0033] The threaded slider 15 is fixedly connected to a positioning buckle 17. There are two positioning buckles 17. When the bidirectional threaded rod 13 is rotated by inserting an adjustment tool into the adjustment groove 14, the symmetrically arranged threaded sliders 15 will move inward or outward synchronously. Throughout the process, the outer wall of the threaded slider 15 is always in close contact with the inner wall of the guide groove 16. With the vertical limiting of the limiting groove 12, it is ensured that the slider moves synchronously in the opposite direction only in the horizontal direction, without tilting or jamming.

[0034] The implementation principle of an adjustable universal automotive side curtain airbag generator bracket in this application embodiment is as follows: The airbag generator 1 serves as a key functional component of the detection device. Two connecting grooves 2, symmetrically arranged around the center of the fixed block housing 5, are opened on its outer wall, providing dedicated assembly slots for the metal connecting strip 3, ensuring precise connection and balanced force. The fixed block housing 5 serves as the main load-bearing structure of the device. Two metal connecting blocks 4, symmetrically arranged around the center of the fixed block housing 5, are fixed to its front, providing rigid support for the subsequent installation of the connecting shaft 6 and connecting shaft 8, preventing structural misalignment from affecting detection accuracy after assembly. The end of the metal connecting strip 3 furthest from the metal connecting block 4 is inserted into the connecting groove 2 on the outer wall of the airbag generator 1, ensuring close contact between the outer wall of the metal connecting strip 3 and the inner wall of the connecting groove 2. The symmetrically arranged connecting grooves 2, in conjunction with the metal connecting strip 3, restrict the horizontal displacement of the airbag generator 1, preventing lateral displacement. Meanwhile, the back of the metal connecting strip 3 is fixedly connected to the front of the metal connecting block 4, forming a preliminary connection path for the fixed block shell 5, the metal connecting block 4, the metal connecting strip 3, and the air curtain generator 1, laying the foundation for subsequent bolt tightening. The end of the metal connecting strip 3 away from the metal connecting block 4 is fixedly connected to the connecting shaft 6, and the back of the connecting shaft 2 8 is fixedly connected to the front of the metal connecting block 4, and the axis of the connecting shaft 6 is aligned with the axis of the connecting shaft 2 8. Insert connecting bolt 7 from the end of connecting shaft 6 furthest from connecting shaft 8, so that connecting bolt 7 penetrates the inner wall of connecting shaft 6 and extends to the inner wall of connecting shaft 8. The connecting shaft 6 and connecting shaft 8 are rigidly fixed through threaded engagement. This structure further strengthens the connection between metal connecting strip 3 and metal connecting block 4, preventing the air curtain generator 1 from loosening due to vibration and ensuring the stability of the device position during testing. The limiting groove 9 on the inner wall of the fixing block housing 5 provides a sliding track for the two metal connecting plates 10. The inner wall of the metal connecting plate 10 slides along the inner wall of the limiting groove 9, allowing for flexible movement along the length of the limiting groove 9, enabling fine-tuning of the installation position of the fixing block housing 5. After the metal connecting plate 10 slides to the target installation position, connecting bolt 11 penetrates the inner wall of the metal connecting plate 10 and extends to the external installation structure, such as a track side frame or sleeper fixing seat. This adjustment function can adapt to the installation spacing of fasteners of different specifications, solving the compatibility problem of traditional fixed brackets that are used for only one type. The limiting groove 12 opened on the inner wall of the fixed block shell 5 forms a double track limiting structure with the guide groove 16 opened at the bottom. The limiting groove 12 restricts the vertical displacement of the threaded slider 15, and the guide groove 16 restricts its lateral displacement, providing a stable sliding path for the threaded slider 15.The bidirectional threaded rod 13, rotatably connected to the inner wall of the fixed block housing 5, has two sections of threads with opposite directions machined on its outer wall. The adjustment groove 14 on the right side can be connected to an adjustment tool, providing an operating interface for manually or mechanically driving the bidirectional threaded rod 13 to rotate. It is the core of the power input for the entire adjustment assembly. Two threaded sliders 15 are symmetrically arranged around the center of the fixed block housing 5. Their inner walls mesh with the opposite threads on the outer walls of the bidirectional threaded rod 13. When the bidirectional threaded rod 13 is rotated by inserting an adjustment tool into the adjustment groove 14, the symmetrically arranged threaded sliders 15 will move synchronously inward or outward. Throughout the process, the outer wall of the threaded slider 15 is always in close contact with the inner wall of the guide groove 16. With the vertical limit of the limiting slide groove 12, it is ensured that the slider moves synchronously in the opposite direction only in the horizontal direction without tilting or jamming. Two positioning buckles 17 fixed on the surface of the threaded slider 15 move synchronously in the opposite direction with the sliding of the threaded slider 15. The adjustable range of the bidirectional adjustment assembly, combined with the sliding adjustment of the original metal connecting plate 10, allows the device to be adapted to different specifications of track fasteners.

[0035] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
