Description

Technical Field

[0001] This utility model relates to the field of composite panel technology, and in particular to a collision testing device for anti-collision composite panels. Background Technology

[0002] The main purpose of crash testing of anti-collision composite panels is to evaluate their performance under specific impact conditions, including the degree of deformation after impact, energy absorption capacity, and buffering effect on impacting objects. Through testing, the safety and reliability of composite panels in practical applications can be understood.

[0003] However, most existing composite plate collision devices are designed to test single composite plates and cannot test multiple composite plates together. This results in limited data collected from collision experiments and makes it difficult to adjust the collision force in batches. Utility Model Content

[0004] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0005] Specifically, the technical problem to be solved by this utility model is to provide a collision testing device for anti-collision composite panels, so as to solve the technical problem that most existing composite panel collision devices often test a single set of composite panels and cannot test multiple sets of composite panels together, which leads to certain limitations in the data collected by the collision experiment and the difficulty in adjusting the collision force in batches.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A collision testing device for a composite anti-collision panel includes a test chamber and a collision assembly disposed on the upper end of the test chamber. The test chamber has four sets of symmetrical sliding rods at both ends of its inner wall, and sliders are fitted onto the outer walls of the sliding rods. A placement assembly is disposed within the inner cavity of the test chamber. A fixing rod is fixed to the inner wall of the test chamber, and a pressure sensor is connected to the front end of the fixing rod. The collision assembly includes first turntables fixedly disposed on both sides of the upper end of the test chamber, symmetrically arranged. A second turntable is disposed at one end of the first turntables, close to each other. A connecting frame is disposed at the middle of the second turntables, close to each other. A collision hammer is disposed at the lower end of the connecting frame. The placement assembly includes a placement frame disposed between the sliders, and the placement frame includes a placement slot inside the placement frame. A notch is formed through the outer wall of the placement frame. Four sets of symmetrical adjusting rods are inserted into the outer wall of one end of the placement frame. An abutment plate is provided at the front end of the adjusting rods on the same side, and a spring is fitted onto the abutment plate at one end of the outer wall of the placement frame.

[0008] As an improved technical solution, the second turntable and the first turntable are rotatably connected at the middle. Several sets of second positioning holes are evenly and circumferentially opened on the outer walls of both sides of the first turntable with the axis of the second turntable as the midpoint. First positioning holes corresponding one-to-one with the second positioning holes are opened on the outer walls of both sides of the second turntable.

[0009] As an improved technical solution, a positioning pin is movably inserted between the second positioning hole and a corresponding set of first positioning holes, the positioning pin moving through the first positioning hole and the second positioning hole.

[0010] As an improved technical solution, the placement frame is concave in shape, and the connecting frame can pass through both ends of the concave opening when rotating around the center of the second turntable.

[0011] As an improved technical solution, the slider is movably sleeved on the outer wall of the slide rod.

[0012] As an improved technical solution, the abutment plate is located in the placement groove, the adjusting rod is movably inserted into the outer wall of the placement frame, and a pull plate is fixedly connected between the two sets of adjusting rods located on the same vertical plane. The front and rear ends of the spring are fixedly connected to the outer wall of the placement frame and the pull plate, respectively.

[0013] As an improved technical solution, the inner wall of the test chamber is provided with scale lines at the upper end of the slide rod.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are:

[0015] This invention features a placement component. Pulling the pull plate outward causes the adjusting rod to slide along the outer wall of the placement frame. Simultaneously, the pull plate stretches the spring, allowing one or more composite plates to be tested to be placed side-by-side between the placement slot and the abutment plate. Then, the pull plate is released, and under the elastic force of the spring, the abutment plate fixes the composite plate in the placement slot. This allows for testing the collision performance of a single composite plate or the combined collision performance of multiple composite plates.

[0016] This invention incorporates a collision assembly. By adjusting the collision force as needed, the connecting frame is rotated upwards, causing the second turntable to rotate along the first turntable. A positioning pin is then inserted between any corresponding first and second positioning holes. When the collision hammer rotates upwards to its highest point on the vertical surface, the downward rotation of the hammer generates the greatest potential energy, resulting in the greatest impact force on the composite plate. The lower the height of the collision hammer is from the highest point on the vertical surface, the smaller the potential energy generated and the smaller the impact force on the composite plate. Using the scale lines, the position of the slider at the top of the slide rod can be adjusted, allowing for rapid adjustment of the impact force on the composite plate, resulting in richer experimental data. Based on the degree of deformation of the composite plate, different impact forces that it can withstand can be tested. Attached Figure Description

[0027] like Figures 1-4 As shown in the figure, this embodiment provides a collision testing device for a composite anti-collision panel, including a test chamber 1 and a collision component 2 disposed on the upper end of the test chamber 1. Four sets of sliding rods 3 are symmetrically arranged at both ends of the inner wall of the test chamber 1. Sliding blocks 4 are sleeved on the outer walls of the sliding rods 3. A placement component 5 is disposed in the inner cavity of the test chamber 1. A fixing rod 7 is fixedly disposed on the inner wall of the test chamber 1, and a pressure sensor 8 is connected to the front end of the fixing rod 7. The collision component 2 includes first turntables 21 symmetrically disposed on both sides of the upper end of the test chamber 1, and a second turntable 22 is disposed at one end of the first turntables 21 that are close to each other. The second turntable 22 is provided with a connecting frame 26 at its middle part close to each other. The lower end of the connecting frame 26 is provided with a collision hammer 27. The placement component 5 includes a placement component 5 located between the sliders 4. The placement component 5 includes a placement frame 51 fixedly located between the sliders 4. The placement frame 51 has a placement groove 52 inside. The outer wall of the placement frame 51 has a through notch 57. Four sets of adjusting rods 53 are inserted into the outer wall of one end of the placement frame 51. The front end of the adjusting rods 53 located on the same side is provided with an abutment plate 56. The abutment plate 56 is fitted with a spring 54 at one end of the outer wall of the placement frame 51.

[0028] The second turntable 22 and the first turntable 21 are rotatably connected at the middle. Several sets of second positioning holes 24 are evenly and circularly opened on both sides of the outer wall of the first turntable 21 with the axis of the second turntable 22 as the center point. First positioning holes 23 are opened on both sides of the outer wall of the second turntable 22, corresponding one-to-one with the second positioning holes 24.

[0029] A positioning pin 25 is movably inserted between the second positioning hole 24 and a corresponding set of first positioning holes 23, and the positioning pin 25 moves through the first positioning hole 23 and the second positioning hole 24.

[0030] The placement frame 51 is concave in shape. When the connecting frame 26 rotates around the center of the second turntable 22, it can pass through both ends of the notch 57.

[0031] The slider 4 is movably mounted on the outer wall of the slider 3.

[0032] The abutment plate 56 is located in the placement groove 52, the adjusting rod 53 is movably inserted into the outer wall of the placement frame 51, and the two sets of adjusting rods 53 located on the same vertical plane are fixedly connected to the pull plate 55. The front and rear ends of the spring 54 are fixedly connected to the outer wall of the placement frame 51 and the pull plate 55, respectively.

[0033] The inner wall of the test chamber 1 has a scale line 6 located at the upper end of the slide bar 3.

[0034] Pull the pull plate 55 outward, causing the adjusting rod 53 to slide along the outer wall of the placement frame 51. Simultaneously, the pull plate 55 stretches the spring 54, placing one or more sets of composite plates to be tested side-by-side between the placement slot 52 and the abutment plate 56. Then, release the pull plate 55; under the elastic force of the spring 54, the abutment plate 56 fixes the composite plates in the placement slot 52. Next, adjust the impact force as needed, and rotate the connecting frame 26 upward. The connecting frame 26 drives the second turntable 22 to rotate along the first turntable 21. Then, insert the positioning pin 25 between any corresponding first positioning hole 23 and second positioning hole 24. When the impact hammer 27 rotates upward to the highest point on the vertical surface, the downward rotation of the impact hammer 27 generates the greatest potential energy, resulting in the greatest impact force on the composite plate. The lower the height of the impact hammer 27 is from the highest point on the vertical surface, the smaller the potential energy generated and the smaller the impact force on the composite plate. Adjust the impact hammer 27 to a suitable height according to the required impact force, remove the positioning pin 25, and gently push the connecting frame 26 forward. The connecting frame 26 moves the impact hammer 27 along the second turntable 22 towards the composite plate in the placement slot 52. The impact hammer 27 passes through the notch 57 and strikes the composite plate. At this time, the kinetic energy of the impact hammer 27 is converted into the kinetic energy of the placement frame 51. The placement frame 51 drives the slider 4 to slide along the slide rod 3 towards the pressure sensor 8. The placement frame 51 strikes the pressure sensor 8. By measuring the vertical pressure of the pressure sensor 8, the impact force on the composite plate can be roughly detected. Thus, based on the degree of deformation of the composite plate after the impact, the impact resistance of the composite plate can be detected. Before the impact test, according to the scale line 6, the position of the slider 4 at the upper end of the slide rod 3 can be adjusted. The closer the composite plate is to the impact hammer 27 at the lowest point on the vertical plane, the greater the impact force on the composite plate.

Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
