Technical Field

[0001] This utility model belongs to the field of testing equipment technology, and mainly relates to a drop test device for objects. Background Technology

[0002] In the research and development testing of power banks, drop testing is an essential component. This drop test involves subjecting the power bank to several drops using a drop testing device to check whether its performance still meets requirements, the extent of damage to the protective casing, and other factors, thereby determining whether the power bank's overall performance meets the requirements.

[0003] Existing drop test devices typically only clamp the object to be tested at a certain height and then release it during testing. However, to ensure the accuracy of the test, the object should be dropped at different tilt angles to maintain the authenticity of the test. Existing test devices generally only clamp the object and lack the function of adjusting the initial posture of the object at different angles. Utility Model Content

[0023] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0024] Example: Please refer to Figures 1-5 A drop test device for an object includes a limiting frame 5, a fixed rod 1 mounted on the limiting frame 5, a movable block 7 adjustablely mounted on the fixed rod 1, a movable frame 2 rotatably connected to the movable block 7, and clamping cylinders 3 symmetrically distributed on the movable frame 2 for clamping the object. The fixed rod 1 has a slot 13. The movable frame 2 includes a U-shaped plate 17, a rotating platform 18, a transition rod 19, and a damping platform 21, which are fixedly connected in sequence. The clamping cylinders 3 are mounted on the U-shaped plate 17. The rotating platform 18 and the damping platform 21 are both rotatably connected to the movable block 7. The transition rod 19 passes through the slot 13. 3. A first wing bolt 14 is threaded onto the movable block 7, and the end of the first wing bolt 14 is tightly attached to the outer circle of the movable block 7. In this embodiment, the object 22 is a power bank. Therefore, when it is necessary to drop the power bank at different tilt angles, after clamping the power bank, simply loosen the first wing bolt 14, then rotate the movable frame 2 at a certain angle, and tighten the first wing bolt 14 to lock the damping platform 21, thereby adjusting the angle of the movable frame 2. Then, a drop test can be performed on the power bank to ensure the authenticity of the test.

[0025] In this embodiment, the rotation of the rotating platform 18 and the moving block 7 is achieved by a bearing connection, thereby ensuring the stable rotation of the moving frame 2. The moving block 7 is provided with a damping hole, and a damping rubber ring 20 is provided on the damping hole. The damping rubber ring 20 is interference-fitted with the damping platform 21, which dampens the rotation of the moving frame 2. The damping force achieves the following effect: when the first wing bolt 14 is loosened, the moving frame 2 will remain stationary even when it is not subjected to external force by the operator; this prevents the moving frame 2 from becoming too "sensitive" during angle adjustment, which would affect the accuracy of angle adjustment; and the end of the first wing bolt 14 passes through the damping rubber ring 20 and is tightly attached to the outer circle of the moving block 7, preventing the damping rubber ring 20 from rotating and ensuring the stability of the damping.

[0026] The end face of the damping hole is provided with an angle scale 16, and the end of the damping platform 21 is provided with a pointer 15 pointing to the angle scale 16, which facilitates the observation of the rotation angle; and the front and rear ends of the fixing rod 1 are respectively provided with two scale bars 12, the two scale bars 12 on the same end face are symmetrically distributed with respect to the slot 13, and the four scale bars 12 are located at the front and rear ends of the fixing rod 1, which facilitates the operator's observation and adjustment at different positions; in addition, the clamping end of the clamping cylinder 3 is generally in the form of a rubber block, and the clamping end is provided with a V-shaped notch, so as to achieve stable clamping of the power bank in different directions. For specific clamping states, please refer to Figures 4-5 The V-shaped notch is beneficial for the stable clamping of the power bank's smaller, wider surface.

[0027] In other embodiments, a horizontal plate 9 is fixedly connected to the movable block 7, and a camera 10 is provided at the bottom of the horizontal plate 9 to facilitate observation of the movement process of the power bank after falling and impact; a dovetail groove 8 is provided on the fixed rod 1, and a boss that cooperates with the dovetail groove 8 is provided on the movable block 7 to facilitate the stability of the movement of the movable block 7; a second wing bolt 11 is threadedly connected to the fixed rod 1, and the end of the second wing bolt 11 passes through the boss and is tightly attached to the inner wall of the dovetail groove 8, thereby realizing the adjustment of different heights of the movable block 7; in addition, an impact plate 4 is detachably installed at the bottom of the limiting frame 5, and the material of the impact plate 4 can be cement, steel plate, etc. Wooden boards or hard soil are used to simulate the ground hardness in a real environment, making the test results closer to actual use. In addition, the limiting frame 5 is equipped with several fire sprinklers 6 connected to the fire protection system. The limiting frame 5 also has several temperature sensors and smoke sensors connected to the fire protection system. The fire protection system can be a common carbon dioxide fire extinguishing system, which will not be elaborated on in this article. As long as the temperature sensors and smoke sensors can send signals to the fire protection system, the fire protection system can perform fire extinguishing operations on the limiting frame 5, thereby preventing the power bank from spontaneously combusting during the test.

[0028] Working principle: When it is necessary to drop the power bank at different tilt angles, after the power bank is clamped by the two clamping cylinders 3, simply loosen the first wing bolt 14, then move the U-shaped plate 17 to rotate it a certain angle, and then tighten the first wing bolt 14 to lock the damping platform 21. This allows for adjustment of the angle of the U-shaped plate 17, enabling the power bank to be tilted at different angles. Subsequently, a drop test can be conducted on the power bank, thus ensuring the authenticity of the test.
