Description

Technical Field

[0001] This invention relates to the field of glass testing technology, and in particular to a device for testing the puncture resistance of laminated glass for research and development. Background Technology

[0002] Laminated glass, as an important safety protection material, is widely used in fields with high safety requirements, such as automotive windshields, rail transit windows, building curtain walls, and skylights, due to its excellent impact resistance and ability to maintain its integrity after breakage. In these applications, laminated glass often needs to withstand high-speed impacts or puncture loads from external objects, such as being hit by flying stones while a vehicle is in motion, head impacts in pedestrian collisions, or falling objects that may strike in the building environment. To ensure its safety and reliability under real working conditions, puncture resistance testing has become a key link in product development and quality control. The common testing method is as follows: first, the glass is placed on a rigid table, then the edges of the glass are fixed with clamps, and then an impact head is dropped vertically from a certain height to hit the glass surface. Afterwards, the glass is observed to determine whether it is penetrated or cracked, in order to judge its puncture resistance.

[0003] However, with the increasing complexity of modern building and transportation designs, the application of curved and curved laminated glass is becoming more widespread, such as in car side windows, building domes, and the streamlined front of high-speed trains. This type of non-planar glass places higher demands on testing equipment, and existing testing devices exhibit significant technical shortcomings when applied to curved glass: First, in real-world conditions, the impact on the glass is often not ideally perpendicular. For example, during vehicle operation, impacts from pedestrian heads, flying stones, and debris are typically oblique, high-speed impacts. Such oblique impacts not only alter the direction of force decomposition but may also trigger more complex stress distributions and failure modes, with failure mechanisms significantly different from those of vertical impacts. Significant differences exist because traditional laminated glass puncture resistance testing devices generally employ a vertical free-fall structure, making it impossible to adjust the impact angle of the impact head. This makes it difficult to simulate common oblique impact conditions in real-world environments, resulting in a lack of comprehensiveness and authenticity in the test results. This limits the accurate assessment of the safety performance of laminated glass under complex usage conditions. Secondly, existing clamping systems lack adaptive adjustment capabilities and cannot match the curved edges with different radii of curvature. This leads to poor contact between the clamp and the glass surface, uneven distribution of clamping force, and insecure clamping, which can easily cause the glass to slip, warp, or shift entirely upon impact. This is especially pronounced when simulating oblique impacts, severely affecting the accurate positioning of the puncture point and the consistency of the stress state. Summary of the Invention

[0004] In view of this, the present invention provides a puncture resistance testing device for laminated glass research and development, which can solve the problems of existing testing devices being unable to simulate the oblique impact conditions commonly seen in real environments when applied to curved glass, resulting in a lack of comprehensiveness and authenticity in the test results, and the shortcomings of existing clamping systems being unable to clamp the glass firmly due to a lack of adaptive adjustment capability.

[0013] The beneficial effects of this invention are as follows: 1. By setting up a support frame, support plate, support rod, limiting rod, and corresponding lifting and telescopic mechanisms, this invention achieves stable and adaptive clamping of curved laminated glass, effectively preventing slippage, warping, or overall displacement during impact testing. This ensures the stability of the glass sample and the consistency of its stress state during the test. Furthermore, by adjusting the support frame to tilt and cooperating with the limiting mechanism to lock the angle, the test angle of the curved glass can be flexibly and accurately adjusted, thereby simulating the oblique impacts commonly encountered in real working conditions. This significantly improves the comprehensiveness, authenticity, and evaluation capability of the test results for actual application environments.

[0014] 2. By setting a guide rod, the operator can place the curved glass using the guide rod's guidance, thus facilitating the operator's placement of the curved glass.

[0015] 3. By setting up a replacement mechanism, combined with the circular track formed by the first guide rail and the second guide rail, the present invention can realize the rapid and automatic switching of impact heads of different shapes or materials. The operator does not need to manually disassemble and assemble, but only needs to drive the rotating frame with the third motor to move the required impact head to the test position, which greatly improves the testing efficiency and the versatility of the equipment, and meets the diverse testing needs of different impact conditions in the research and development stage.

[0039] See Figure 11 and Figure 12 As shown, the limiting mechanism includes a movable block 1101, a sliding plate 1102, and a brake caliper 1103.

[0040] See Figure 14 and Figure 15As shown, the lifting mechanism includes a connecting frame 1501, a movable plate 1502, a second spring 1503, a gear plate 1504, a first rotating shaft 1505, a first gear 1506, and a second motor 1507. Connecting frames 1501 are provided on both the front and rear sides of the bottom of the support plate 13, and movable plates 1502 are slidably arranged within each of the two connecting frames 1501. Two sets of support rods 14 at the top of the same support plate 13 are slidably connected to the two movable plates 1502 respectively, with the lower side of the support rods 14 and the bottom of the movable plates 1502 connected together. A second spring 1503 is connected; both movable plates 1502 are connected to toothed plates 1504 at their bottoms, and the toothed plates 1504 slide through the bottom of the connecting frame 1501; a first rotating shaft 1505 is rotatably mounted on the lower side of the support plate 13; two first gears 1506 are mounted on the first rotating shaft 1505, and the two first gears 1506 mesh with the two toothed plates 1504 respectively; a second motor 1507 is mounted on the lower front side of the support plate 13, and the output shaft of the second motor 1507 is connected to the front end of the first rotating shaft 1505.

[0041] See Figures 16-18 As shown, the telescopic mechanism includes a second rotating shaft 1901, a second transmission component 1902, a second gear 1903, a first tooth block 1904, and a third spring 1905; the second rotating shaft 1901 is rotatably mounted on the upper side of the support plate 13; the second transmission component 1902 includes a synchronous pulley and a synchronous belt, and synchronous pulleys are provided in the middle of the first rotating shaft 1505 and the middle of the second rotating shaft 1901, with a synchronous belt wound between the two synchronous pulleys, and the first rotating shaft 1505 and the second rotating shaft 1901 are driven by the synchronous pulleys and the synchronous belt; four second gears 1903 are connected at intervals on the second rotating shaft 1901; first tooth blocks 1904 are evenly spaced on the outer side of the movable tube 17, and the first tooth blocks 1904 mesh with the second gears 1903; a third spring 1905 is connected between the inner side of the movable tube 17 and the limiting rod 18.

[0042] In the initial state, because the abutment 704 abuts against the touch plate 701, the touch plate 701 limits the linkage structure of the lever frame 702, thereby causing the first spring 703 to be in a stretched state;

[0043] In use, first pull the cabinet door of cabinet 1 to open it. Then, drive the two support plates 13 to move simultaneously via the electric slide rail 12 to adjust the distance between the two support plates 13 so that the curved glass can be placed between the tops of the two support plates 13. After adjustment, place the curved glass between the tops of the two support plates 13 (with the test area of ​​the curved glass facing upwards), so that the support rod 14 is located on the inside of the curved glass and the limiting rod 18 is located on the outside of the curved glass. Then, drive the first rotating shaft 1505 via the second motor 1507. Rotating clockwise causes the first gear 1506 to rotate clockwise, which in turn moves the gear plate 1504 and the movable plate 1502 upwards. This, in turn, causes the movable plate 1502 to move the support rod 14 upwards via the second spring 1503. Simultaneously, when the first rotating shaft 1505 rotates clockwise, it drives the second rotating shaft 1901 and the second gear 1903 to rotate clockwise via the second transmission component 1902. This causes the second gear 1903 to drive the movable tube 17 via the first tooth block 1904. Extending from the curved tube 16, the movable tube 17, via the third spring 1905, moves the limiting rod 18 closer to the curved glass. When the supporting rod 14 contacts the inner surface of the curved glass, the inner surface of the curved glass abuts against the supporting rod 14, stopping its upward movement. Then, as the movable plate 1502 continues to move upward, the second spring 1503 stretches, applying an upward force to the supporting rod 14 through deformation, thus supporting the inner surface of the curved glass. Furthermore, when the limiting rod 18 contacts the curved glass... When the outer surface of the glass comes into contact, the outer surface of the curved glass will abut against the limiting rod 18, causing the limiting rod 18 to stop moving. Then, as the movable tube 17 continues to extend from the curved tube 16, the third spring 1905 is compressed. The third spring 1905 applies pressure to the limiting rod 18 through deformation, causing the limiting rod 18 to press against the outer surface of the curved glass. In this way, by applying pressure to the inner and outer surfaces of the curved glass through the support rod 14 and the limiting rod 18, the support rod 14 and the limiting rod 18 can clamp the end area of ​​the curved glass, thereby limiting the curved glass.

[0044] Subsequently, follow-up steps are performed according to requirements. If a vertical puncture test is required on the curved glass, no additional operation is needed. If an oblique puncture test is required, the first motor 1001 drives the lead screw 1002 to rotate via the first transmission component 1003. This causes the lead screw 1002 to move the sleeve 1004 to the left, thereby causing the sleeve 1004 to press against the support frame 9 through the connecting plate 1005 and rotate counterclockwise. This, in turn, causes the electric slide rail 12, support plate 13, and curved glass to rotate counterclockwise, thereby adjusting the inclination of the support frame 9, electric slide rail 12, and support plate 13, and thus adjusting the curvature. The orientation of the glass is adjusted until the surface of the curved glass forms a certain angle with the movement trajectory of the first impact head 6. During this period, when the support frame 9 rotates counterclockwise, the support frame 9 will drive the slide plate 1102 to slide on the movable block 1101, causing the slide plate 1102 to drive the movable block 1101 to rotate, so that the movable block 1101 adapts to the posture change of the slide plate 1102. After the orientation of the curved glass is adjusted, the slide plate 1102 is braked by the brake caliper 1103 to limit the sliding of the slide plate 1102, and then the slide plate 1102 limits the support frame 9 to ensure the stability of the tilt angle of the support frame 9.

[0045] Then, the cabinet door of cabinet 1 is pushed to close in reverse. Subsequently, the winch 4 unwinds the steel cable, releasing it from the sliding frame 3. This causes the sliding frame 3, the first guide rail 5, the first impact head 6, and the touch plate 701 to fall downwards under gravity. The first impact head 6 then impacts the surface of the curved glass, performing a puncture test. During this process, when the touch plate 701 moves downwards and separates from the stop rod 704, the first spring 703 returns to its original position. The first spring 703 drives the locking rod frame 702 downwards, causing it to engage with the groove of the first impact head 6, thus locking the first impact head 6 and preventing it from detaching from the first guide rail 5. Simultaneously, the downward movement of the locking rod frame 702 causes the touch plate 701 to rotate via a linkage structure. After the first impact head 6 impacts the curved glass, the winch 4 winds up the steel cable, causing the cable to pull the sliding frame 3 upward. This, in turn, moves the first guide rail 5, the first impact head 6, and the touch plate 701 upward to reset. When the touch plate 701 moves upward to contact the abutment rod 704, the abutment rod 704 will press the touch plate 701 to reverse and reset. This causes the touch plate 701 to move the locking rod frame 702 upward to reset via the linkage structure. The first spring 703 is stretched, causing the locking rod frame 702 to leave the groove of the first impact head 6, thus unlocking the first impact head 6. In this way, the puncture test of the curved glass can be completed. During this process, the camera 8 can continuously observe the puncture test of the curved glass and obtain the test results based on the surface condition of the curved glass.

[0046] After the curved glass test is completed, the operation is carried out according to the state of the support frame 9. If the support frame 9 is not tilted, no additional operation is required. If the support frame 9 is tilted, the brake on the slide plate 1102 is released by the brake caliper 1103, so that the slide plate 1102 releases the limit on the support frame 9. Then, the first motor 1001 drives the lead screw 1002 to reverse through the first transmission component 1003, so that the lead screw 1002 drives the sleeve 1004 to move to the right to reset. This causes the sleeve 1004 to pull the support frame 9 to rotate clockwise to reset through the connecting plate 1005, thereby driving the electric slide rail 12, the support plate 13 and the curved glass to rotate clockwise to reset. During the clockwise rotation reset of the support frame 9, the support frame 9 will drive the slide plate 1102 to slide on the movable block 1101 to reset, so that the slide plate 1102 drives the movable block 1101 to reverse to reset.

[0047] After the support frame 9 returns to its original state, pull the cabinet door of cabinet 1 again to open it. Then, the second motor 1507 drives the first rotating shaft 1505 to rotate counterclockwise, thereby driving the first gear 1506 to rotate counterclockwise. This causes the first gear 1506 to drive the toothed plate 1504 and the movable plate 1502 to move downwards and reset. During this process, the second spring 1503 gradually returns to its original state. At the same time, when the first rotating shaft 1505 rotates counterclockwise, it will drive the second rotating shaft 1901 and the second gear 1903 to rotate counterclockwise through the second transmission component 1902. This causes the second gear 1903 to drive the movable tube 17 to retract into the arc-shaped tube 16 through the first toothed block 1904, thereby... The third spring 1905 gradually returns to its original state. When the second spring 1503 returns to its original state, the movable plate 1502 will drive the support rod 14 to move downwards and reset through the second spring 1503, so that the support rod 14 is separated from the inner surface of the curved glass. When the third spring 1905 returns to its original state, the movable tube 17 will drive the limiting rod 18 to move away from the curved glass and reset through the third spring 1905, so that the limiting rod 18 is separated from the outer surface of the curved glass, thereby releasing the end area of ​​the curved glass from the support rod 14 and the limiting rod 18, and thus releasing the limiting of the curved glass. After that, the curved glass that has completed the test can be taken out from between the tops of the two support plates 13, and then the cabinet door of the cabinet 1 can be pushed to reverse and close.

[0048] See Figure 13 As shown, it also includes guide rods 20; guide rods 20 are symmetrically arranged at the top front and back of the support plate 13, and the guide rods 20 are used to guide the curved glass.

[0049] By setting up the guide rod 20, the operator can use the guide rod 20 to place the curved glass, thus making it convenient for the operator to place the curved glass.

[0050] See Figures 6-8As shown, it also includes a replacement mechanism, which includes a fixed frame 21, a rotating frame 22, a second guide rail 23, a third motor 24, a third gear 25, a second gear block 26, and a second impact head 27; a fixed frame 21 is installed on the upper front side of the cabinet 1; a rotating frame 22 is rotatably mounted inside the fixed frame 21, and a second guide rail 23 is rotatably mounted on the upper side of the rotating frame 22. The second guide rail 23 is arc-shaped and contacts the first guide rail 5, forming a ring guide rail through contact; a fixed frame 21 is installed on the front side of the cabinet 1. There is a third motor 24; a third gear 25 is connected to the output shaft of the third motor 24; second tooth blocks 26 are evenly spaced on the inner side of the rotating frame 22, and the third gear 25 meshes with the second tooth blocks 26; second impact heads 27 are slidably arranged on the second guide rail 23 at intervals. The types of second impact heads 27 are different, so that different second impact heads 27 can be replaced before testing to test the curved glass. The top of the second impact head 27 is also provided with a slot, so that after replacement, the second impact head 27 can be locked into the slot by using the clamping rod bracket 702.

[0051] By setting up a replacement mechanism, when the first impact head 6 needs to be replaced, the third motor 24 can drive the third gear 25 to rotate, so that the third gear 25 drives the rotating frame 22 to rotate through the second tooth block 26. This causes the rotating frame 22 to push the first impact head 6 and the second impact head 27 to slide on the annular guide rail formed by the first guide rail 5 and the second guide rail 23, thereby adjusting the position of the first impact head 6 and the second impact head 27 until the required second impact head 27 is fully inserted into the first guide rail 5. In this way, when the sliding frame 3 and the first guide rail 5 fall downwards under gravity, the first guide rail 5 can drive the required second impact head 27 to fall downwards, so that the required second impact head 27 can perform a puncture test on the curved glass, thus making it convenient for the operator to use different second impact heads 27 to test the curved glass.
