[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figures 1 to 6This utility model provides a technical solution: a test device for the impact resistance performance of an anti-glare panel, comprising a support frame 1 and a bracket 8. The support frame 1 is located on one side of the bracket 8, and the bottom of the support frame 1 is at the same horizontal position as the bottom of the bracket 8. A lower base 2 is fixedly connected to one end of the support frame 1. An upper base 3 is slidably connected to the surface of the lower base 2 on the support frame 1. A first lead screw 4 is rotatably connected inside the support frame 1. One end of the upper base 3 passes through the support frame 1 and is threaded to the outer wall of the first lead screw 4. 1. A movable frame 5 is slidably connected to the surface of the other end. A second lead screw 6 is rotatably connected inside the movable frame 5. An indexing disk 7 is slidably connected to the outer wall of the movable frame 5. One end of the indexing disk 7 passes through a strip-shaped groove on the surface of the movable frame 5 and is threadedly connected to the outer wall of the second lead screw 6. A first fixing member 9 is fixedly connected to the top of the lower base 2 and the bottom of the upper base 3. A second fixing member 10 is slidably connected to the top of the lower base 2 and the bottom of the upper base 3. A screw rod 11 is threadedly connected to one end of the outer wall of the lower base 2 and the upper base 3.
[0026] The indexing disk 7 is internally connected to a drive gear 701 and a driven gear 702, which mesh together. The outer wall of the indexing disk 7 is rotatably connected to a positioning steering head 703. The bottom of the positioning steering head 703 is rotatably connected to a movable steering head 704. A pendulum 705 is fixedly connected to the upright at the bottom of the movable steering head 704. A limit pin 706 is provided below the pin connection point between the movable steering head 704 and the positioning steering head 703. The limit pin 706 passes through a through hole on the surface of the movable steering head 704 and is inserted into a corresponding slot on the inner wall of the positioning steering head 703.
[0027] The top of the bracket 8 is rotatably connected to the bottom of the first bogie 801. The top of the first bogie 801 is rotatably connected to one end of the second bogie 802 via a universal joint. The other end of the second bogie 802 is rotatably connected to the limit clamp 803 via a universal joint.
[0028] In this embodiment, as Figure 1 and Figure 2 As shown, the upper base 3 and the first lead screw 4 form a helical transmission structure and a lifting structure above the lower base 2. The axis of the upper base 3 and the axis of the lower base 2 are located on the same vertical center line. At the same time, the lower base 2 and the support frame 1 are integrally connected. By rotating the first lead screw 4, the height of the upper base 3 can be easily adjusted to accommodate anti-glare panels of different heights. In this way, no matter what the specific height of the anti-glare panel is, it can be ensured that its upper and lower ends are stably clamped by the upper base 3 and the lower base 2 respectively, which improves the versatility of the test device for anti-glare panels of different specifications.
[0029] In this embodiment, as Figure 1 and Figure 4 As shown, one end of the support frame 1 has a long strip-shaped groove for sliding connection of the movable frame 5. The surface of the groove adjacent to the lower base 2 has a threaded through hole. The surface of the T-shaped slider at the bottom of the movable frame 5 has a threaded through hole of the same specification. The movable frame 5 is threaded to the surface of the support frame 1 through the threaded through hole on the surface of the T-shaped slider at the bottom via a quick-release bolt. When installing and removing the anti-glare plate, the slidable movable frame 5 can be flexibly adjusted. When the anti-glare plate needs to be installed, the movable frame 5 can be slid open to make room for the anti-glare plate. The operator can easily place the anti-glare plate between the lower base 2 and the upper base 3 for fixation. At the same time, during the test, the movable frame 5 is threadedly fixed to the support frame 1 via quick-release bolts to ensure the effective progress of the subsequent test.
[0030] In this embodiment, as Figure 5 As shown, the driven gear 702 is coaxially connected to the positioning steering head 703, and a pointer is fixedly connected to one side of the outer wall of the positioning steering head 703. Angle markings are engraved on the surface of the indexing pendulum 7. Simultaneously, the indexing pendulum 7 forms a lifting structure on the outer wall of the moving frame 5 via a second lead screw 6 that constitutes a helical transmission structure with it. The angle markings on the surface of the indexing pendulum 7, combined with the pointer fixedly connected to one side of the outer wall of the positioning steering head 703, allow the test personnel to intuitively read the rotation angle of the pendulum 705. This makes the setting and adjustment of the impact angle more convenient and accurate, improving the efficiency and precision of the test operation. In actual road use, the anti-glare panel will be impacted at different heights on its surface. For example, a vehicle collision may occur at the top, middle, or bottom of the anti-glare panel. By adjusting the height of the pendulum 705 through the lifting structure of the indexing pendulum 7, the impact conditions at these different positions can be accurately simulated. Impact tests can be conducted on different areas of the anti-glare panel surface to comprehensively evaluate its overall impact resistance performance.
[0031] In this embodiment, as Figure 4 and Figure 5 As shown, one end of the pendulum 705 is conical, and a force sensor is installed inside the conical shape. The axis of the pendulum 705 and the axis of the lower base 2 are on the same axis in a horizontal position. At the same time, the pendulum 705 rotates 180° on the surface of the indexing disk 7 through the positioning and steering head 703 coaxially connected to the driven gear 702. The conical shape of one end of the pendulum 705 allows the impact force to be more concentrated on the anti-glare plate, simulating an impact scenario closer to reality. At the same time, the force sensor installed inside the conical shape can directly and accurately measure the magnitude of the impact force generated when the pendulum 705 hits the anti-glare plate. Furthermore, the tester can precisely set the starting angle of the pendulum 705 according to different test requirements to simulate the impact that the anti-glare plate may receive under different conditions.
[0032] In this embodiment, as Figure 6 As shown, the limiting clamp 803 consists of an L-shaped base plate and two vertical plates that are attached to the surface of the L-shaped base plate. One vertical plate is integrally connected to the L-shaped base plate, and the other vertical plate is movably connected to the surface of the L-shaped base plate by a spring. A laser displacement sensor is tightly attached between the two vertical plates. Because the spring is retractable, the limiting clamp 803 can adapt to laser displacement sensors of different sizes and is also very easy to install and remove.
[0033] In this embodiment, as Figure 3 As shown, both the first fixing member 9 and the second fixing member 10 are composed of a transverse beam plate, a sponge body, and a trapezoidal rubber pad. The transverse beam plate and the trapezoidal rubber pad are bonded together by the sponge body. The shaft end of one end of the screw 11 passes through the interior of the lower base 2 and the upper base 3, and is rotatably connected to one end of the second fixing member 10 corresponding to the top and bottom of the lower base 2 and the upper base 3. Firstly, the distance of the second fixing member 10 can be adjusted by the screw 11, so that the distance between it and the first fixing member 9 can be adjusted, thus accommodating anti-glare panels of different thicknesses. Secondly, since the anti-glare panel is not a regular shape, and the sponge and rubber body have a certain degree of elasticity, the first fixing member 9... The second fixing member 10 can adaptively adjust to fit the surface of the anti-glare plate within a certain range. The sponge and rubber body can be compressed to adjust the contact pressure between the fixing member and the anti-glare plate, ensuring a reliable fixing effect at all times. This adaptability allows the test device to be used to test anti-glare plates of various specifications, improving the versatility and applicability of the device. Furthermore, the trapezoidal rubber body greatly increases the coefficient of friction, which enables the anti-glare plate to be firmly fixed between the first fixing member 9 and the second fixing member 10 during the test.
[0034] The method of use and advantages of this utility model: The anti-glare plate impact resistance testing device works as follows:
[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the test device is first fixed to the test table through the mounting holes on the surface of the support frame 1. The bottom end of the anti-glare plate to be tested is placed at the position of the first fixing member 9 on the surface of the lower base 2, so that one side of the anti-glare plate is in contact with the surface of the first fixing member 9. During fixing, the center position of the anti-glare plate should be aligned with the midpoint position of the first fixing member 9 as much as possible. Depending on the thickness of the anti-glare plate, the screw 11 on one side of the lower base 2 is rotated to adjust the position of the second fixing member 10 on the surface of the lower base 2, so that it is tightly in contact with the other side of the anti-glare plate. The height of the anti-glare plate is usually 70cm to 1.1m. The first lead screw 4 can be driven to rotate by the servo motor, which will drive the upper base 3 to descend to a suitable distance. Using the first fixing member 9 and the second fixing member 10 on the surface of the upper base 3, the same operation as the lower base 2 is performed. In this operation, the top of the anti-glare plate is fixedly clamped, and the strain gauge is adhered to the area of the anti-glare plate to be tested using tape. The strain gauge can be connected to an external data acquisition device via wires. The position of the laser displacement sensor inside the limit clamp 803 is adjusted. Utilizing the rotation structure of the first bogie 801 and the second bogie 802, the laser sensor beam illumination angle is adjusted. The sliding frame 5 is moved to the vicinity of the slot closest to the lower base 2 on the surface of the support frame 1, and secured with quick-release bolts. The power is turned on, and the servo motor drives the drive gear 701 to rotate, which in turn drives the driven gear 702, causing the positioning steering head 703, the movable steering head 704, and the pendulum 705 to rotate. The rotation angle of the pendulum 705 is displayed by the pointer on the surface of the positioning steering head 703. After rotating to the required test angle, the power is turned off. With the power off, pull out the limit pin 706. Under the gravity of the pendulum 705, the movable steering head 704 rotates downward along the pin connection point with the positioning steering head 703. The pendulum 705 strikes the anti-glare plate. If the impact height of the pendulum 705 needs to be adjusted, it can be achieved by rotating the second lead screw 6. The strain gauge, force sensor, and laser displacement sensor can all be connected to the data acquisition device via wires to convert analog signals into digital signals. Depending on the model of the selected sensor and data acquisition device, the acquired data can be transmitted to an external display device via serial communication, USB interface, Ethernet, etc. Based on the metal resistance strain effect, the anti-glare plate deforms under impact, causing the strain gauge to deform and change its resistance value. This change is converted into an electrical signal by the circuit, thereby detecting the anti-glare plate. Surface strain; while the laser displacement sensor uses the principle of laser beam emission and reflection. By measuring the time difference between the emitted and received lasers or by triangulation, when the anti-glare plate is impacted and displaced or deformed, the distance between the sensor and the surface of the anti-glare plate changes, thus monitoring the displacement of the anti-glare plate in real time; when the pendulum 705 strikes the anti-glare plate, the impact force acts on the force sensor, causing physical changes in the sensitive element inside the sensor. These physical changes are converted into electrical signals. The magnitude of the impact force when the pendulum 705 strikes the anti-glare plate is determined by measuring the magnitude of the electrical signal. The above sensor transmits the electrical signal to the data acquisition device. Finally, the display device will react to this data through the data acquisition device electrically connected to it, and analyze and process it through relevant software.
