Description

Technical Field

[0001] This utility model relates to the field of testing device technology, specifically a suitcase drop testing device. Background Technology

[0002] During the production of suitcases, drop tests are typically conducted. This test is usually performed early in the design and manufacturing stages of the suitcase to ensure it can withstand the forces of drops and impacts in real-world use. Drop testing equipment is typically used to simulate drop scenarios that a suitcase might experience during normal use. A search revealed Chinese patent publication number CN221056017U, which discloses a drop testing device for suitcases, including a base, a guide frame, a guide rod, a threaded rod, and a first servo motor. The guide frame is bolted to the upper rear of the base, the guide rod is connected to the front of the guide frame, the threaded rod is rotatably connected to the front of the guide frame, and the first servo motor is bolted to the upper rear of the guide frame.

[0003] While the above-mentioned technical solutions can effectively limit the tilt of the luggage, improve the diversity of the testing process, and make the test results more complete, the fixed base structure used to support the luggage cannot simulate the situation of the suitcase falling on different ground surfaces, thus reducing its versatility. Furthermore, manual assistance is required when adjusting the angle of the luggage through the limiting mechanism, which increases the workload. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a suitcase drop test device, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a suitcase drop test device, comprising a base, a first receiving plate placed on the upper surface of the base, a placement frame fixedly installed on one side of the upper surface of the base, a plurality of second receiving plates sequentially placed inside the placement frame, a lifting mechanism fixedly installed on one side of the upper surface of the base, an angle adjustment mechanism installed on the outer surface of the lifting mechanism, an adjustable clamping mechanism for clamping the suitcase fixedly connected to one end of the angle adjustment mechanism, and a protective mechanism installed on the upper surface of the base.

[0006] Preferably, the lifting mechanism includes a bracket fixedly installed on the upper surface of the base, a first motor fixedly installed on the top of the bracket, a one-way lead screw fixedly connected to the output shaft of the first motor, a movable block slidably connected to the inner wall of the bracket on the outer surface of the one-way lead screw, and an angle adjustment mechanism fixedly installed on one side of the movable block. The operation of the first motor can drive the adjustable clamping mechanism to lift and lower, thereby driving the clamped suitcase to be lifted.

[0007] Preferably, the angle adjustment mechanism includes a second motor fixedly installed on one side of the movable block, the output shaft of the second motor being fixedly connected to a connecting frame, a third motor fixedly installed on one side of the connecting frame, the output shaft of the third motor being fixedly connected to a connecting block rotatably connected to the inner wall of the connecting frame, and an adjustable clamping mechanism fixedly installed on one side of the connecting block. The rotation of the second motor and the third motor can respectively drive the adjustable clamping mechanism to rotate, thereby changing the angle of the suitcase.

[0008] Preferably, the adjustable clamping mechanism includes a mounting frame fixedly installed on one side of the connecting block. Two movable frames are symmetrically slidably connected inside the mounting frame. A fourth motor is fixedly installed on the top of the movable frames. A bidirectional lead screw is fixedly connected to the output shaft of the fourth motor. Two clamping plates for clamping suitcases are symmetrically threaded on the outer surface of the bidirectional lead screw. The rotation of the fourth motor drives the bidirectional lead screw to rotate, and the two clamping plates on one side can move relative to each other through the threads, which is convenient for clamping suitcases of different sizes.

[0009] Preferably, two cylinders are symmetrically fixedly installed at the top center of the mounting frame. The movable end of the cylinder is fixedly connected to a slider that is fixedly connected to the top of the corresponding movable frame. The top of the mounting frame has two sliding grooves that cooperate with the sliders. The cylinders have a fast execution speed, which can quickly retract the clamps on both sides, thereby allowing the suitcase to fall freely.

[0010] Preferably, the protective mechanism includes two L-shaped baffles symmetrically fixedly connected to the top of the base. One end of each of the two L-shaped baffles is rotatably connected to a protective plate via a hinge, which can protect the area around the base and thus prevent debris from flying when the suitcase breaks.

[0020] In this technical solution, the first receiving plate 2 and the multiple second receiving plates 4 are made of different materials, such as steel plates, concrete, or asphalt boards. When conducting drop tests on the suitcase, different receiving plates can be selected for drop tests, thus allowing drop tests on different sides of the suitcase. This adapts to different ground conditions and testing requirements, improving the accuracy and versatility of the test. Example 2

[0021] like Figure 1 and Figure 2As shown, a lifting mechanism 5 is fixedly installed on one side of the upper surface of the base 1. The lifting mechanism 5 includes a bracket 51 fixedly installed on the upper surface of the base 1. A first motor 52 is fixedly installed on the top of the bracket 51. A one-way lead screw 53 is fixedly connected to the output shaft of the first motor 52. A moving block 54 that is slidably connected to the inner wall of the bracket 51 is threadedly connected to the outer surface of the one-way lead screw 53. An angle adjustment mechanism 6 is fixedly installed on one side of the moving block 54.

[0022] The first motor 52 rotates, driving the one-way lead screw 53 to rotate. Through the screw, it can drive the moving block 54 and the adjustable clamping mechanism 6 to lift and lower, thereby lifting the suitcase. Example 3

[0023] like Figure 1 and Figure 2 As shown, an angle adjustment mechanism 6 is installed on the outer surface of the lifting mechanism 5. The angle adjustment mechanism 6 includes a second motor 61 fixedly installed on one side of the moving block 54. The output shaft of the second motor 61 is fixedly connected to a connecting frame 62. A third motor 63 is fixedly installed on one side of the connecting frame 62. The output shaft of the third motor 63 is fixedly connected to a connecting block 64 that is rotatably connected to the inner wall of the connecting frame 62. An adjustable clamping mechanism 7 is fixedly installed on one side of the connecting block 64.

[0024] The rotation of the second motor 61 and the third motor 63 can drive the suitcase to rotate at different angles without manual adjustment, thus meeting different testing needs and fully simulating various drop postures that may occur in actual use, improving the accuracy and reliability of the test. Example 4

[0025] like Figures 1 to 3 As shown, one end of the angle adjustment mechanism 6 is fixedly connected to an adjustable clamping mechanism 7 for holding a suitcase. The adjustable clamping mechanism 7 includes a mounting frame 71 fixedly installed on one side of the connecting block 64. Two movable frames 72 are symmetrically slidably connected inside the mounting frame 71. A fourth motor 73 is fixedly installed on the top of the movable frame 72. The output shaft of the fourth motor 73 is fixedly connected to a bidirectional lead screw 74. Two clamping plates 75 for holding the suitcase are symmetrically threaded on the outer surface of the bidirectional lead screw 74. Two cylinders 76 are symmetrically fixedly installed at the center of the top of the mounting frame 71. The movable end of the cylinder 76 is fixedly connected to a slider 77 that is fixedly connected to the top of the corresponding movable frame 72. Two grooves 78 that cooperate with the sliders 77 are opened on the top of the mounting frame 71.

[0026] The rotation of the fourth motor 73 drives the bidirectional lead screw 74 to rotate, which in turn drives the two clamping plates 75 on one side to move relative to each other through the screw thread, making it convenient to clamp suitcases of different sizes. The relative movement of the clamping plates 75 on both sides is controlled by the cylinder 76, which can quickly clamp and release the suitcase, thereby simulating the free fall of the suitcase. Example 5

[0027] like Figure 1 and Figure 2 As shown, a protective mechanism 8 is installed on the upper surface of the base 1. The protective mechanism 8 includes two L-shaped baffles 81 that are symmetrically fixedly connected to the top of the base 1. One end of each of the two L-shaped baffles 81 is rotatably connected to a protective plate 82 via a hinge.

[0028] Two L-shaped baffles 81 and a protective plate 82 can be used to enclose the area around the test site to prevent debris from flying and improve safety.

[0029] Working principle: The first support plate 2 and multiple second support plates 4 are made of different materials, such as steel plates, concrete, or asphalt boards. When conducting drop tests on suitcases, different support plates can be selected for drop tests, thus allowing drop tests on different sides of the suitcase. This adapts to different ground conditions and testing requirements, improving the accuracy and versatility of the test.

[0030] The first motor 52 rotates, driving the one-way lead screw 53 to rotate. Through the thread, it drives the moving block 54 and the adjustable clamping mechanism 6 to rise and fall, thereby lifting the suitcase. The second motor 61 and the third motor 63 rotate, respectively, driving the suitcase to rotate at different angles without manual adjustment, thus meeting different testing needs and fully simulating various drop postures that may occur in actual use, improving the accuracy and reliability of the test. The fourth motor 73 rotates, driving the two-way lead screw 74 to rotate. Through the thread, it drives the two clamping plates 75 on one side to move relative to each other, facilitating the clamping of suitcases of different sizes. The relative movement of the clamping plates 75 on both sides is controlled by the cylinder 76, which can quickly clamp and release the suitcase, thus simulating the free fall of the suitcase.

[0031] Two L-shaped baffles 81 and a protective plate 82 can be used to enclose the area around the test site to prevent debris from flying and improve safety.
