[0002] Laminated glass is made of two or more layers of glass bonded with an elastic layer in the middle (such as PVB film, EVA film, etc.), and has strong anti-breakage performance. With the wide application of laminated glass in high-rise buildings, transportation and other fields, the requirements for its impact performance are becoming increasingly stringent, especially when subjected to external impact or pressure, effectively evaluating the impact resistance of laminated glass has become the key.

[0003] Existing impact test methods for laminated glass mainly rely on traditional impact sources, such as pendulum impact test, steel ball falling impact test, etc. These methods have shortcomings in practical applications. Traditional testing equipment can usually only simulate vertical impact, and the impact angle is difficult to accurately control. It cannot reflect the inclined or tilted impact scenarios that laminated glass may encounter in actual use. In fact, laminated glass may be impacted from different angles, especially in transportation or architectural glass. The impact angle has an important influence on the fracture mode and impact resistance.

[0004] In addition, the traditional method has low accuracy in adjusting the impact speed and energy. The impact energy is usually adjusted by changing the height of the pendulum or the weight of the impact body. This method makes it difficult to accurately control the applied impact speed and energy, and cannot meet the needs of high-precision impact testing. Summary of the invention

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] In the description of the present invention, it should be understood that terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “top”, “bottom”, “inside” and “outside” indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0021] like Figure 1-Figure 9 As shown, the detection device proposed in this embodiment includes a sample fixing component 100, an electromagnetically driven impact test component 200 and an adjustment frame 300, wherein the sample fixing component 100 is connected to the adjustment frame 300, and the electromagnetically driven impact test component 200 is arranged on the adjustment frame 300, wherein a glass plate clamp 101 is provided on the sample fixing component 100, and the glass plate clamp 101 is configured to clamp and fix the laminated glass; the electromagnetically driven impact test component 200 includes an impact body 201, an impact acceleration track 202 and an AC electromagnetic acceleration coil 203, the impact body 201 and the AC electromagnetic acceleration coil 203 are arranged on the impact acceleration track 202, the material of the impact body 201 includes magnetic metal, and the AC electromagnetic acceleration coil 203 is configured to electromagnetically accelerate the impact body 201; a test component base 305 is slidably provided on the adjustment frame 300, and the electromagnetically driven impact test component 200 is arranged on the test component base 305.

[0022] When this embodiment is used, the electromagnetically driven AC electromagnetic acceleration coil 203 in the impact test assembly 200 accelerates the impact body 201 through electromagnetic force, so that it reaches a preset speed and is ejected on the impact acceleration track 202. When the impact body 201 contacts the laminated glass clamped on the sample fixing assembly 100, the impact test is completed; the AC electromagnetic acceleration coil 203 accurately controls the acceleration of the impact body by adjusting the magnitude, frequency and duration of the current, thereby achieving precise adjustment of the impact body speed, thereby simulating impact scenes of different intensities.

[0023] The AC electromagnetic acceleration coil 203 makes the acceleration process of the impact body 201 more controllable and precise. Through the current intensity and frequency of the AC electromagnetic acceleration coil 203, the speed and acceleration of the impact body 201 can be accurately controlled, thereby realizing the adjustment of the impact energy and impact speed. It can not only realize the acceleration of the impact body quickly and stably, but also allow the mass and speed of the impact body to be adjusted under different test conditions to meet the test requirements of laminated glass samples of different thicknesses.

[0024] This embodiment also includes an adjustment frame 300 and a sliding test assembly base 305 thereon, so that the electromagnetically driven impact test assembly 200 can be precisely adjusted in multiple directions. By adjusting the position and angle of the test assembly base 305, multi-angle impact testing of the impact body can be achieved, such as simulating impacts at different angles such as vertical and inclined surfaces, so that the device can flexibly adapt to various testing requirements, especially for the impact performance testing of laminated glass in different application environments, providing higher flexibility.

[0025] The electromagnetically driven impact test assembly 200 is set on the test assembly base 305. By adjusting the position of the test assembly base 305, the posture of the electromagnetically driven impact test assembly 200 can be accurately adjusted, thereby achieving flexible adjustment of the impact angle and position.

[0026] In this embodiment, the electromagnetically driven impact test assembly 200 further includes a laser indicator 204, which is precisely mounted on the test assembly base 305 and aligned parallel to the impact acceleration track 202. The laser indicator 204 forms an indicating light path parallel to the motion trajectory of the impact body 201 by emitting a laser beam. When performing an impact test, the laser emitted by the laser indicator 204 will project a clear point on the laminated glass sample. By observing the position of the laser projection, the tester can accurately determine the landing point of the impact body 201, thereby ensuring the accuracy of the impact test.

[0027] With the aid of the laser pointer 204, the tester can intuitively monitor the landing point of the impact body without relying on calculations or manually adjusting the position of the equipment, thereby reducing the possibility of human error and making it easier to perform multiple precise impacts on a specific area, which is suitable for scenarios where fine impact testing is required at a specific position or angle.

[0028] The impact acceleration track 202 in this embodiment is provided with a plurality of track rollers 207 on a directional array along the track at the bottom, and each track roller 207 is connected to the impact acceleration track 202 by rotation, and the track roller 207 enables the impact body 201 to move smoothly on the track; when performing an impact test, the impact body 201 is accelerated along the path of the track roller 207 and finally ejected, and the rotation of the track roller 207 reduces the friction between the impact body 201 and the impact acceleration track 202, so that the impact body can move more smoothly along the track, ensuring that the impact body maintains a stable trajectory during the acceleration process, reducing energy loss and speed fluctuation caused by friction, thereby improving the accuracy and consistency of the test.

[0029] The electromagnetic driven impact test assembly 200 in this embodiment also includes a recovery wire 205 and a hoisting wire drum 206. The two ends of the recovery wire 205 are respectively connected to the impact body 201 and the hoisting wire drum 206. When the impact test is carried out, the AC electromagnetic acceleration coil 203 pushes the impact body 201 to accelerate and eject along the impact acceleration track 202 through electromagnetic force. The impact body 201 will drag the recovery wire 205 while moving along the track. After the impact body 201 hits the laminated glass sample, the recovery wire 205 begins to be tightened, and the hoisting wire drum 206 automatically pulls the impact body 201 back to its original position by winding the recovery wire 205. Through this recovery system, the impact body 201 can quickly and smoothly return to the impact acceleration track 202 to prepare for the next test.

[0030] Through the cooperation of the recovery pull wire and the winch drum, the impact body 201 can be quickly and automatically recovered after each test, reducing manual intervention and the complexity of operation, thereby saving time and labor costs. At the same time, the automatic recovery mechanism ensures the stability and accuracy of the impact body 201, so that the impact body can be quickly put back into the next test, maintaining the high efficiency of the test, improving experimental efficiency and reducing equipment wear.

[0031] The sample fixing assembly 100 in this embodiment includes a fixed back plate 102, a clamping jaw adjustment groove 106, a fixing bolt 104 and an impact pad 105. The glass plate clamping jaw 101 is fixed in the clamping jaw adjustment groove 106 by the fixing bolt 104. The clamping jaw adjustment groove 106 is designed as an adjustable structure, which allows the position of the glass plate clamping jaw 101 on the fixed back plate 102 to be adjusted according to glass samples of different sizes. The tester can flexibly adjust the position of the clamping jaw according to the actual size of the sample to ensure that the clamping jaw can firmly clamp laminated glass of various sizes and ensure the stability of the glass in the impact test.

[0032] In addition, an impact pad lining plate 105 is provided on the fixed back plate 102, and the lining plate is located between the fixed back plate 102 and the laminated glass. The provision of the impact pad lining plate 105 reduces the risk of the glass sample being subjected to uneven pressure, thereby ensuring the stability of the glass during the test, and at the same time preventing friction or damage that may be caused when the fixed back plate 102 is in direct contact with the laminated glass.

[0033] In this embodiment, the adjustment frame 300 includes key components such as a rotating joint 302, a lifting bracket 303 and a vertical track 304. The lifting bracket 303 is connected to the adjustment frame through the rotating joint 302, so that the lifting bracket 303 can realize rotational movement under the action of the rotating joint 302. A vertical track 304 is arranged on the lifting bracket 303, and the test assembly base 305 is slidably installed in the vertical track 304, and can be freely lifted and rotated in the track; when the test assembly base 305 moves up and down or rotates along the vertical track 304, the electromagnetically driven impact test assembly 200 on the test assembly base 305 will also be adjusted with the movement of the base, so that the impact body 201 can perform impact tests on the laminated glass at different angles and positions, ensuring that the device can flexibly adapt to different experimental needs and simulate multiple impact angles and positions.

[0034] Through the cooperation between the lifting bracket 303 and the rotating joint 302, the adjustment frame 300 can realize multi-angle and multi-position adjustment of the electromagnetic driven impact test assembly 200, so that the device can simulate more complex impact situations, such as the situation where laminated glass is subjected to an inclined or tilted impact, thereby more realistically reflecting the impact situation in actual applications.

[0035] The adjustment frame 300 proposed in this embodiment also includes a mobile chassis 301, a rotating joint 302 is arranged on the mobile chassis 301, and then a lifting bracket 303 is arranged on the rotating joint 302. The lifting bracket 303 can be rotated through the rotating joint 302. At the same time, a moving wheel group 306 is arranged at the bottom of the mobile chassis 301. The mobile chassis 301 can realize its own movement with the help of the moving wheel group 306. When the lifting bracket 303 moves and rotates with the mobile chassis 301, the test component base 305 moves synchronously therewith, thereby realizing the posture adjustment of the electromagnetic driven impact test component 200, so that the height, position and pointing angle of the electromagnetic driven impact test component 200 can be adjusted, and impact tests at various angles and positions can be realized.

[0036] Meanwhile, a test track 103 is provided on the fixed back plate 102 , and the mobile chassis 301 moves on the test track 103 . The test track 103 limits the moving range of the mobile chassis 301 , so that the mobile chassis 301 can move along a specific path when needed.

[0037] In this embodiment, a support rod 307 is provided on the lifting bracket 303 to improve the stability of the lifting bracket 303 during operation. When the center of gravity of the electromagnetically driven impact test assembly 200 is at a higher position, the support rod 307 can support the lifting bracket 303 to ensure that it does not tilt or become unstable during rotation or lifting. A universal wheel 308 is provided at the bottom of the support rod 307, so that the support rod 307 can adjust its position as the lifting bracket 303 rotates or moves, providing more flexible support. The universal wheel 308 can not only ensure the smooth movement of the lifting bracket 303 during rotation, but also can conveniently adjust the position of the support rod 307 when needed, to ensure the balance and stability of the overall system.

[0038] When using the laminated glass detection device of this embodiment, first check that all parts of the equipment are working properly and ensure that the electromagnetic driven impact test assembly, adjustment frame and sample fixing assembly are intact; fix the laminated glass sample on the sample fixing assembly, and adjust the clamping claws to ensure that the sample is firmly fixed; according to the test requirements, adjust the height, position and angle of the test assembly base by adjusting the lifting bracket and the rotating joint, and use the laser indicator to calibrate the exact landing point of the impact body; after starting the electromagnetic acceleration system, adjust the acceleration coil current to accelerate the impact body, and observe its smooth acceleration along the track; when performing the impact test, the impact body hits the glass sample and records the impact data; after the test, the impact body is automatically recovered by recovering the pull wire and the winch drum, and prepare for the next test; adjust the equipment to perform multiple impact tests as needed, ensure the precise position and angle of each impact by the laser indicator, and complete data recording and analysis; finally, clean the equipment and check each component, and perform necessary maintenance and care.
