When one component is considered to be "provided on" another component, it can be directly provided on the other component or can exist with a middle component. The terms "top", "bottom", "upper", "lower", "left", "right", "front", "back", and the like used herein are for illustrative purposes only.

[0045] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments can be combined with each other in the case of no conflict.

[0046] Please refer to Figures 1-6 The embodiments of the present application provide a tempered film strength testing device 100, comprising a frame assembly 10, an impact mechanism 20 and a placing platform 30.

[0047] The frame assembly 10 is arranged along a vertical direction. The impact mechanism 20 is fixedly connected with the frame assembly 10, and the impact mechanism 20 slides along the vertical direction. The placing platform 30 is fixedly connected with the frame assembly 10 and the impact mechanism 20 respectively, the placing platform 30 is placed on the ground, and the placing platform 30 is arranged below the impact mechanism 20.

[0048] The placement platform 30 includes a fixed component 31, a placement slot 32, and a positioning piece 33. The fixed component 31 is connected with the rack component 10, and the fixed component 31 is attached to the tempered film. The placement slot 32 is located in the fixed component 31, and the direction away from the impact mechanism 20 is defined as the first direction F1. The placement slot 32 is opened along the first direction F1, and the tempered film is located in the placement slot 32. The positioning piece 33 is arranged opposite to the impact mechanism 20, and the positioning piece 33 is located in the placement slot 32. The tempered film is attached to the positioning piece 33, and after impact, the impact piece 222 is attached to the tempered film.

[0049] Specifically, the rack component 10 is arranged along the vertical direction to provide stable structural support for the entire device. Its role is to provide support for other components and ensure that the test device does not tilt or shift during operation, thereby ensuring the accuracy of the experiment.

[0050] The impact mechanism 20 is fixedly connected with the rack component 10 and can slide along the vertical direction, which means that the impact mechanism 20 can move freely in the vertical direction to simulate the impact force during a fall or collision.

[0051] The placement slot 32 contains the tempered film to ensure its positioning and accuracy, avoiding displacement or uneven stress during impact, and providing an effective carrier. The positioning piece 33 is arranged opposite to the impact mechanism 20 and is located in the placement slot 32. The tempered film is attached to the positioning piece 33 to ensure that the impact force is applied to the target position of the tempered film without deviation, thereby achieving precise testing. Finally, after impact, the impact piece 222 is attached to the tempered film, which ensures that the direct impact force of the impact is concentrated on the stress area of the tempered film, simulating the impact effect in actual application and effectively evaluating the impact resistance of the tempered film.

[0052] The impact mechanism 20 is fixedly connected with the rack component 10 and can slide along the vertical direction to simulate different impact strengths. The placement platform 30 is located below the impact mechanism 20 to provide a stable support surface. The tempered film is precisely positioned by the fixed component 31 and the placement slot 32, avoiding displacement during testing. The positioning of the positioning piece 33 further ensures the precise positioning of the tempered film, allowing the impact force to be concentrated on the target position of the tempered film. In this way, the design of the impact piece 222 attached to the tempered film can efficiently transfer the impact force, avoiding uneven distribution of force during testing, and enhancing the accuracy and reliability of the test results.

[0053] In a specific embodiment, in the impact state, the impact mechanism 20 is slidingly connected with the rack component 10 along the first direction F1 and is attached to the tempered film. In the non-impact state, the impact mechanism 20 is located above the placement platform 30 and is not attached to the tempered film.

[0054] Specifically, in the impact state, the impact mechanism 20 is slidingly connected with the rack assembly 10 along the first direction F1 and adheres to the tempered film. The key of the impact state is to apply high-precision impact force through the impact mechanism 20. In the non-impact state, the impact mechanism 20 is located above the placement platform 30 and does not adhere to the tempered film. This design ensures that the impact mechanism 20 does not interfere with the normal placement of the tempered film in the non-test state, avoiding unnecessary force during the test process.

[0055] In the non-impact state, the position of the impact mechanism 20 is reasonably controlled so that it does not directly contact the tempered film, which can avoid external force interference to the tempered film during the test process. In the impact state, the impact mechanism 20 slides along the first direction F1 and adheres to the tempered film. This switching mechanism ensures that the impact force is applied accurately and only when needed, thereby improving the controllability and reliability of the test results.

[0056] In a specific embodiment, the impact mechanism 20 includes a sliding assembly 21 and an impact assembly 22. The second direction F2 opposite to the first direction F1, the sliding assembly 21 is fixedly connected with the placement platform 30 along the second direction F2, and the sliding assembly 21 is arranged in the same direction as the rack assembly 10. The impact assembly 22 is slidingly connected with the sliding assembly 21, the impact assembly 22 is located above the placement platform 30, and the impact assembly 22 is connected with the driving assembly 40.

[0057] In a specific embodiment, the impact assembly 22 includes a fixed plate 221 and an impact piece 222. The impact piece 222 is a component located on the fixed plate 221, arranged in the vertical direction, and fixedly connected with the fixed plate 221. The main function of the impact piece 222 is to simulate the actual drop or impact and apply impact force to the tempered film. The design of the impact piece ensures the accurate application of impact force, enhancing the reliability of the test results. The connection between the impact piece 222 and the fixed plate 221 ensures that the impact force is concentrated on the target area of the tempered film, thereby improving the accuracy of the test.

[0058] Specifically, the sliding assembly 21 is fixedly connected with the placement platform 30 along the second direction F2 and arranged in the same direction as the rack assembly 10, which enables the impact mechanism 20 to freely slide to the set position, providing flexibility for impact testing. The impact assembly 22 is slidingly connected with the placement platform 30 through the sliding assembly 21 and has a certain adjustability, which can ensure that the impact force can be accurately transmitted to the tempered film, avoiding test deviation caused by position error. This structure improves the test precision, ensures the uniform distribution of impact force, and avoids damage caused by local impact.

[0059] The sliding connection between the sliding assembly 21 and the impact assembly 22 ensures that the impact mechanism 20 can move accurately, avoiding errors or deviations during testing. The use of the impact assembly 22 in conjunction with the sliding assembly 21 can ensure that the impact force is evenly applied during the impact process, resulting in uniform stress on the tempered film and more reliable test results. The connection between the sliding assembly 21 and the rack assembly 10 further improves the stability and accuracy of the device.

[0060] In practical applications, the sliding assembly 21 and the impact assembly 22 can be adjusted in position according to different testing requirements to ensure that the impact force can be accurately applied to the tempered film. This structural design is widely used in impact tests of tempered films, glass screens, and other impact-resistant materials, especially when multiple tests of different samples are required, the adjustability of the device is particularly important.

[0061] Specifically, the impact assembly 22 includes a fixed plate 221 and an impact piece 222, wherein the fixed plate 221 is arranged opposite to the placement platform 30 in the vertical direction and has a connecting hole, and the sliding assembly 21 is connected to the fixed plate 221 through the connecting hole. The impact assembly 22 is allowed to slide freely in the vertical direction, ensuring the accurate application of impact force. The impact piece 222 is fixedly connected to the fixed plate 221 and is arranged along the first direction F1, which ensures that the impact force is directly applied to the tempered film, effectively simulating the actual drop impact scenario and enhancing the accuracy of the test results.

[0062] The sliding connection between the fixed plate 221 and the sliding assembly 21 ensures that the impact assembly 22 can move freely during testing and accurately position the stress point of the tempered film. The fixed connection of the impact piece 222 to the fixed plate 221 and the arrangement along the first direction F1 ensure that the impact force is concentrated on the target area of the tempered film, thereby improving the accuracy of the test and avoiding unnecessary errors.

[0063] In a specific embodiment, the sliding assembly 21 includes a sliding rod 211, a sliding block 212, and a connecting plate 213. The sliding rod 211 is arranged along the second direction F2, and the sliding rod 211 is connected to the placement platform 30. Two sliding rods 211 are located at the length ends of the placement platform 30. The sliding block 212 is fixedly connected to the connecting hole. One sliding block 212 is sleeved on one sliding rod 211, and the sliding block 212 is slidably connected to the sliding rod 211. The connecting plate 213 is connected to the fixed plate 221, and the two ends of the connecting plate 213 are bolted to the two sliding rods 211.

[0064] Specifically, the sliding rod 211 is arranged along the second direction F2, which mainly provides a support path for the sliding assembly 21 and is connected with the placement platform 30. Through the layout at both ends of the length direction of the placement platform 30, the sliding rod 211 can uniformly bear the sliding pressure of the impact mechanism 20, thereby ensuring the stability and precision during the operation of the test equipment. The beneficial effect is to reduce the shaking or deviation of the sliding assembly 21 during the impact operation, further improving the reliability of the test.

[0065] The sliding block 212 is fixedly connected with the fixed plate 221 through the connecting hole and is sleeved on the sliding rod 211, and is in sliding connection with the sliding rod 211. The design of the sliding block 212 allows the impact assembly 22 to freely slide along the sliding rod 211, thereby realizing the smooth movement of the impact mechanism 20 in the second direction F2. Its role is to serve as the core moving part of the sliding assembly 21, ensuring smooth operation when the test equipment switches between different impact points. The beneficial effect is to optimize the dynamic performance of the equipment, reduce the friction resistance and jamming problem during movement, and improve the test efficiency.

[0066] The connecting plate 213 is connected with the fixed plate 221, and both ends thereof are fixed on the two sliding rods 211 by bolts, respectively. The design of the connecting plate 213 is mainly used to provide a rigid structure for the impact assembly 22, ensuring that the sliding rods 211 maintain an accurate spacing, avoiding deformation or loosening due to uneven stress during operation. The beneficial effect is to strengthen the integrity of the entire sliding assembly 21, improve the impact resistance, and prolong the service life of the equipment.

[0067] In a specific embodiment, the sliding rod 211 includes a sliding part 2111, a first buffer part 2112, and a second buffer part 2113. The sliding block 212 and the fixed plate 221 are respectively sleeved on the sliding part 2111. The first buffer part 2112 is sleeved on one end of the sliding part 2111, the first buffer part 2112 is respectively attached to the connecting plate 213 and the sliding block 212, and the first buffer part 2112 is located between the connecting plate 213 and the sliding block 212. The second buffer part 2113 is sleeved on the other end of the sliding part 2111, and the second buffer part 2113 is located between the placement platform 30 and the fixed plate 221.

[0068] Specifically, the sliding part 2111 is the main component of the sliding rod 211, which provides stable support and sliding path for the sliding block 212 and the fixed plate 221. The sliding block 212 and the fixed plate 221 are both sleeved on the sliding part 2111, ensuring that there is no deviation or instability phenomenon when moving on the sliding part 2111. Its role is to provide smooth sliding conditions for the sliding block 212, while maintaining the relative position relationship between the fixed plate 221 and the sliding block 212. The beneficial effect is to enhance the stability of the sliding assembly 21, reduce the interference of friction and vibration on the test results, thereby ensuring the precision and reliability of the impact testing equipment.

[0069] The first buffer part 2112 is sleeved on one end of the sliding part 2111, adheres to the connecting plate 213 and the sliding block 212, and is located between the two. Its role is to absorb part of the force when the sliding block 212 is impacted or slides to the limit position, reducing the rigid impact when the sliding block 212 hits the connecting plate 213. The beneficial effect is to effectively reduce the wear of the sliding block 212 and the vibration of the equipment, thereby prolonging the service life of the sliding assembly 21, while improving the stability and test safety of the impact testing equipment.

[0070] The second buffer part 2113 is sleeved on the other end of the sliding part 2111, adheres to the fixed plate 221 and the placement platform 30. Its role is to provide effective buffer support when the fixed plate 221 is stressed or slides to the limit due to impact testing, preventing the fixed plate 221 from directly impacting the placement platform 30. The beneficial effect is to protect the core components of the equipment from excessive impact force, while ensuring the smooth distribution of stress during the impact testing process, further optimizing the performance of the testing equipment.

[0071] In a specific embodiment, the first buffer part 2112 is a rubber part, and the second buffer part 2113 is a spring.

[0072] Specifically, the rubber part as the material of the first buffer part 2112 has good elasticity and pressure resistance, which can absorb part of the impact energy during the movement of the sliding assembly 21, thereby reducing the direct impact force between the connecting plate 213 and the sliding block 212, avoiding hard impact between the sliding block 212 and the sliding part 2111, and protecting the integrity of the equipment structure. The flexible properties of the rubber part can also effectively reduce high-frequency vibration, improve the stability of the equipment during the strength test, and make the test results more accurate.

[0073] The spring serves as the second buffer 2113 and mainly functions to provide further energy absorption and recovery capability for the sliding part 2111. When the fixed plate 221 or the sliding block 212 is impacted, the spring accumulates energy by deformation and gradually releases the energy, thereby slowing down the speed and intensity of the impact effect transmitted to the placement platform 30, and avoiding damage to the test platform. In addition, the spring has a restoring force, which can help the sliding assembly 21 to recover to the initial position, thereby improving the repeated test efficiency of the equipment. The combination of the spring and the rubber piece forms a double-buffering design, which takes into account both flexible buffering and recovery capability.

[0074] In an embodiment, the fixed assembly 31 comprises a first fixed piece 311 and a second fixed piece 312.

[0075] The first fixed piece 311 is located at one end close to the impact mechanism 20. The second fixed piece 312 is located at an end away from the impact mechanism 20, and the second fixed piece 312 overlaps the first fixed piece 311.

[0076] Specifically, the first fixed piece 311 is arranged at one end close to the impact mechanism 20, and directly adheres to the tempered film, for limiting the movement of the tempered film that may occur during the test. The function is to fix the front end of the film body, to ensure that the tempered film remains stable under the action of the impact force during the test, thereby improving the accuracy of the test. The design of the first fixed piece 311 helps to uniformly distribute the external force received by the tempered film, avoiding damage to the film body due to single-point stress, and thus more accurately reflecting the overall strength characteristics of the film body.

[0077] The second fixed piece 312 is located at an end away from the impact mechanism 20, and overlaps the first fixed piece 311. The second fixed piece 312 is used to fix the other end of the tempered film, to provide bidirectional support for the film body, and further improve the stability thereof. The overlapping design ensures the complete fixing of the tempered film in the longitudinal direction, avoiding test errors caused by insufficient tension or uneven support. By fixing both ends, a clamping effect in the vertical direction is formed, so that the tempered film is uniformly stressed during the impact test, reflecting the true strength thereof.

[0078] In an embodiment, a fixed gap 313 is formed between the first fixed piece 311 and the second fixed piece 312, and the tempered film is placed in the fixed gap 313 and adheres to the positioning piece 33, forming a vertical abutment.

[0079] Specifically, the fixed gap 313 between the first fixing member 311 and the second fixing member 312. The fixed gap 313 provides a space to accommodate the tempered film, ensuring that the tempered film can be stably placed in the fixing assembly 31. The size of the fixed gap 313 is reasonably set, which can accurately clamp tempered films of different thicknesses without causing additional indentation or stress on their surfaces. This design not only ensures the stability of the film body, but also avoids mechanical damage caused by excessive clamping, thereby improving test accuracy and repeatability.

[0080] The tempered film is placed in the fixed gap 313 and is in contact with the positioning member 33. The placement of the tempered film directly determines its stress state during testing. Through the action of the positioning member 33, the tempered film is tightly attached to the positioning member 33 in the fixed gap 313, further limiting the lateral and longitudinal displacement of the film body, especially providing vertical support during impact testing. This design ensures that the stress path of the tempered film during testing is clear, making the test results more realistic and consistent.

[0081] The positioning member 33 forms an abutting support in the vertical direction by attaching to the back of the tempered film, which can effectively disperse the impact force and prevent the tempered film from breaking due to uneven local stress. This abutting method, through structural optimization, ensures the stability of the tempered film under high-strength testing, improving the application range and reliability of the testing equipment.

[0082] In a specific embodiment, the positioning member 33 is provided with an impact groove 331, and the shape of the impact groove 331 matches the shape of the impact piece 222. After impact, the impact piece 222 is located in the impact groove 331.

[0083] Specifically, the impact groove 331 provides a fixed guide and action area for the impact piece 222, and its shape matches the impact piece 222, which can effectively ensure the accuracy of the impact force application position and avoid inaccurate test results due to impact deviation from the target area. At the same time, the impact groove 331 can constrain the movement trajectory of the impact piece 222 after impact, preventing the impact piece 222 from rebounding or shifting and causing secondary damage to the tempered film and equipment. This design significantly improves the accuracy and safety of impact testing.

[0084] The matching relationship between the impact piece 222 and the impact groove 331 ensures uniform distribution of the impact force. The shape of the impact groove 331 can be accurately matched according to the shape of the impact piece 222, avoiding local stress concentration caused by uneven contact area or contact point deviation, and improving the authenticity of tempered film strength testing. In addition, this structure also allows the design of various shapes of impact grooves 331 and impact pieces 222 to adapt to the testing needs of tempered films of different types or shapes, enhancing the application range of the equipment.

[0085] When the impact is completed, the impact piece 222 is embedded in the impact groove 331, and part of the impact energy can be absorbed by the structural characteristics of the groove body, reducing the vibration and impact force of the equipment. This design plays a key role in protecting the equipment and the test sample, while providing a stable initial state for subsequent testing and improving test efficiency.

[0086] Therefore, the strength test equipment 100 for tempered film provided above can ensure that the tempered film is accurately positioned and kept stable through the fixing assembly 31 and the placing groove 32 in the placing platform 30, so as to avoid inaccurate test results caused by force deviation; the positioning piece 33 further enhances the fixing effect, so as to ensure that the acting force of the impact mechanism 20 and the tempered film is concentrated on the target position. The accuracy and repeatability of the test results are improved, so that the impact resistance of the tempered film can be more effectively evaluated.

[0087] The above only describes the embodiments of the present application, and it should be pointed out that those skilled in the art can make improvements without departing from the creative concept of the present application, but these all belong to the protection scope of the present application.
