[0041] like Figures 1 to 3As shown, the present invention provides an impact simulation device, which includes an impact platform 1 and a release device 2. The release device 2 includes a workbench 21, a rotating shaft 22, a connecting assembly 23 and a swing rod 27. The connecting assembly 23 includes a shaft fork 231 and a vertical shaft 232 arranged on the shaft fork 231. The rotating shaft 22 is rotatably arranged on the workbench 21. The shaft fork 231 can rotate around the axis of the vertical shaft 232. The vertical shaft 232 is vertically connected to the rotating shaft 22. The swing rod 27 is arranged on the shaft fork 231. The product to be tested can be fixed on the swing rod 27. The swing rod 27 can be rotated and adjusted around its own axis. The swing rod 27 can rotate around the axis of the rotating shaft 22 under the action of gravity, driving the product to be tested thereon to collide with the impact platform 1. In this embodiment, the product under test is fixed on the swing rod 27, and the swing rod 27 is set on the rotating shaft 22 through the shaft fork 231 and the vertical shaft 232. Since the rotating shaft 22 is rotatably set on the workbench 21, and the swing rod 27 can rotate around the rotating shaft 22 under the action of gravity to drive the product under test thereon to collide with the impact platform 1, the impact platform 1 cooperates with the release device 2 to perform an impact simulation test on the product under test; since the swing rod 27 is rotatably matched with the rotating shaft 22 through the shaft fork 231 and the vertical shaft 232, and since the shaft fork 231 can rotate around the vertical shaft 232 and the rotating shaft 22 is rotatably set on the workbench 21, the shaft fork 231 and the vertical shaft 232 can rotate. 32 and the rotating shaft 22 form a universal connection structure. By rotating the shaft fork 231, the product under test on the swing arm 27 can be flexibly moved, and can be aligned with the impact platform 1 at any angle and position, so that the damage of the product under test under different impact scenarios can be obtained, which greatly improves the practicality of the impact simulation device. At the same time, because the swing arm 27 can rotate around its own axis, the swing arm 27 can drive the product under test thereon to rotate, so that different positions on the product under test collide with the impact platform 1, further improving the practicality of the impact simulation device, thereby facilitating the staff to perform impact tests on a certain position of the product under test. Specifically, a support frame 29 is provided on the workbench 21, and the rotating shaft 22 is horizontally arranged on the support frame 29 and rotates with the support frame 29 through a bearing; the impact platform 1 is coated with an asphalt layer, a cement layer or other coating to simulate real road conditions, so as to obtain test results that are closer to the actual situation; the swing arm 27 simulates the user's arm, and the product under test is a bracelet or smart watch. The product under test is fixed near the end of the swing arm 27 to simulate the user's wrist.

[0042] Furthermore, if Figure 1 and Figure 2As shown, the release device 2 further includes a force-applying assembly 24 connected to the workbench 21. The force-applying assembly 24 is capable of applying a force to the swinging rod 27 to move it closer to the impact platform 1. In this embodiment, the force-applying assembly 24 is disposed on the workbench 21 and above the swinging rod 27. The force-applying assembly 24 is capable of applying a force to the swinging rod 27 to move it closer to the impact platform 1, thereby increasing the speed and force of the collision between the product under test and the impact platform 1, thereby meeting a wider range of simulated test conditions.

[0043] Specifically, if Figure 2 As shown, the force-applying assembly 24 includes an elastic member 241, a push plate 242, and a stopper 243. The stopper 243 is connected to the workbench 21, the push plate 242 is disposed on the stopper 243, and the elastic member 241 is disposed between the push plate 242 and the stopper 243. The elastic member 241 is capable of applying an elastic force to the push plate 242 to move it toward the impact platform 1. In this embodiment, the stopper 243 is connected to the workbench 21, and the push plate 242 is movably disposed on the stopper 243. The elastic member 241 is capable of applying an elastic force to the push plate 242 to move it toward the impact platform 1, thereby increasing the speed and force of the tested product when it collides with the impact platform 1. Specifically, the elastic member 241 is a spring.

[0044] Specifically, if Figure 2 and Figure 4 As shown, the force-applying assembly 24 further includes a first assembly rod 244, which is fixedly connected to the workbench 21 and extends toward the impact platform 1. A stopper 243 is adjustably mounted on the first assembly rod 244. In this embodiment, the end of the first assembly rod 244 is fixed to the workbench 21, and the stopper 243 is detachably mounted on the first assembly rod 244. A worker can adjust the position of the stopper 243 on the first assembly rod 244 to adjust the thrust of the elastic member 241 on the push plate 242.

[0045] Specifically, if Figure 2 As shown, the blocking seat 243 includes a seat body 2431 and a second assembly rod 2432 fixedly connected to the seat body 2431. The second assembly rod 2432 extends toward the impact platform 1. The seat body 2431 is slidably mounted on the first assembly rod 244. The push plate 242 is mounted on the second assembly rod 2432. The ends of the elastic member 241 respectively abut against the push plate 242 and the seat body 2431. In this embodiment, the seat body 2431 is mounted on the first assembly rod 244 and is tightened with bolts. After the bolts are removed, the seat body 2431 can slide on the first assembly rod 244. The second assembly rod 2432 is parallel to the first assembly rod 244. The push plate 242 is mounted on the second assembly rod 2432 and can slide along the second assembly rod 2432. A stopper is provided at the end of the second assembly rod 2432 to prevent the push plate 242 from falling off the second assembly rod 2432.

[0046] Furthermore, the force-applying assembly 24 also includes a support rod 245, one end of which is fixed on the workbench 21, and the other end is connected to the end of the first assembly rod 244, thereby forming a triangular structure between the support rod 245, the first assembly rod 244 and the workbench 21, thereby ensuring the structural stability of the entire force-applying assembly 24.

[0047] Furthermore, if Figure 2 and Figure 3 As shown, the connecting assembly 23 also includes a fixed block 233, which is fixedly connected to the rotating shaft 22, and the vertical shaft 232 is rotatably connected to the fixed block 233. In this embodiment, the shaft fork 231 is a fork-shaped structure surrounded on both sides, and the fixed block 233 is a cube structure. The fixed block 233 is fixedly connected to the middle part of the rotating shaft 22; the two ends of the vertical shaft 232 are fixed to the two opposite side plates of the shaft fork 231. The vertical shaft 232 is perpendicular to the rotating shaft 22 and is arranged in the fixed block 233 and rotates with the fixed block 233 through a bearing. Therefore, the shaft fork 231 can simultaneously rotate the vertical shaft 232 and the rotating shaft 22, so that the product under test on the swing arm 27 can be moved to any position relative to the impact platform 1. In conjunction with the rotation of the swing arm 27, the product under test can be subjected to impact simulation at any angle relative to the impact platform 1.

[0048] Specifically, if Figure 2 and Figure 4 As shown, the release device 2 also includes a rotation positioning assembly 25, which includes a pin 251 and a toothed disk 252. The toothed disk 252 is coaxially connected to the swing rod 27. The toothed disk 252 has multiple slots evenly spaced along the circumference, and the pin 251 is inserted into any slot. In this embodiment, a toothed disc 252 is coaxially mounted on the swinging rod 27. A controllable latch 251 is provided on the shaft fork 231. When the latch 251 is inserted into a slot on the outer periphery of the toothed disc 252, the swinging rod 27 is locked and cannot rotate. This allows the operator to rotate the swinging rod 27 upward about the rotation axis 22 to the test height. Subsequently, the operator releases the swinging rod 27, causing it to rotate about the rotation axis 22 and fall downward. During this process, the latch 251 disengages from the slot in the toothed disc 252, ensuring that the swinging rod 27 is in a free-rotating state at the moment of impact with the impact platform 1, consistent with the actual arm movement of a user during a fall. Specifically, the slot on the shaft fork 231 corresponding to the toothed disc 252 is marked with an angle value to facilitate recording of the angle during each test. The latch 251 is made of iron and can be controlled by an electromagnetic control device to quickly insert or remove it from the slot in the toothed disc 252.

[0049] Furthermore, if Figure 2 and Figure 3As shown, the release device 2 also includes an angle limiting assembly 26, which includes a limiting shaft 261 and a fixing frame 262. The fixing frame 262 is fixedly connected to the workbench 21, and the limiting shaft 261 is coaxially connected to the rotating shaft 22 and can be rotatably set on the fixing frame 262; the limiting shaft 261 is provided with a limiting surface 2611, and the rotating shaft 22 is provided with a control surface 221. When the rotating shaft 22 rotates, the control surface 221 can push against the limiting surface 2611. In this embodiment, the limiting shaft 261 is arranged on the fixing frame 262, and the control surface 221 of the rotating shaft 22 can be pushed against the limiting surface 2611 of the limiting shaft 261, thereby limiting the rotation range of the rotating shaft 22; specifically, before each impact test, the staff sets the test height of the product to be tested and rotates the limiting shaft 261 to the corresponding angle. When the rotating shaft 22 rotates to a certain position, it is blocked. At this time, the product to be tested on the swing arm 27 is correspondingly lifted to the specified test height, which makes it convenient for the staff to record the test height each time and ensures the accuracy of the test.

[0050] Furthermore, if Figure 4 As shown, the impact simulation device also includes a lifting component 3, which includes a mounting plate 31 and a lifting drive 32 connected to each other. The impact platform 1 is arranged on the mounting plate 31, and the lifting drive 32 can drive the mounting plate 31 to move vertically. In this embodiment, the lifting drive 32 is a cylinder, and the piston rod of the lifting drive 32 is connected to the mounting plate 31. The impact platform 1 is arranged on the mounting plate 31. Therefore, the impact platform 1 can move vertically under the drive of the lifting drive 32 to adjust the distance from the product being tested on the swing rod 27, thereby further expanding the test range of the impact simulation device; specifically, the lifting component 3 also includes a plurality of guide rods 33, which are arranged vertically and cooperate with the mounting plate 31 through linear bearings. Therefore, the mounting plate 31 can move along the guide rods 33 during the movement, ensuring that the impact platform 1 Stability and accuracy of vertical movement; in addition, the impact simulation device also includes a first driving member 6, the first driving member 6 is fixedly mounted on the mounting plate 31, the first driving member 6 is a motor, and the first driving member 6 is connected to the impact platform 1 through a chain. The impact platform 1 can rotate around its own axis under the drive of the first driving member 6. When the product under test on the release device 2 collides with the impact platform 1, there is a relative speed between the two, so the real friction process when the product under test contacts the ground can be simulated, thereby highly restoring the damage to the product under test during the user's dynamic fall.

[0051] Furthermore, if Figure 4As shown, the release device 2 also includes a second drive member 28, which is used to drive the swing arm 27 to rotate upward about the rotation axis 22, thereby raising the product under test to the test height. Specifically, the second drive member 28 is a pneumatic cylinder, located below the shaft fork 231 in the height direction. The piston rod of the second drive member 28 extends upward to abut against the shaft fork 231 and drive the shaft fork 231 to rotate about the rotation axis 22. After the product under test is raised to the test height, the piston rod of the second drive member 28 rapidly descends and retracts, causing the swing arm 27 to rotate downward under the action of gravity, ultimately driving the product under test to collide with the impact platform 1 below.

[0052] Furthermore, if Figure 4 and Figure 5 As shown, the impact simulation device also includes an installation box 5 and a supporting plate 4, and the installation box 5 includes an upper box body 51 and a lower box body 52; the workbench 21 and the second driving member 28 are fixedly connected to the supporting plate 4; an avoidance hole for the vertical passage of the impact platform 1 is opened on the supporting plate 4; an upper box body 51 is arranged above the supporting plate 4, and the upper box body 51 encloses the impact platform 1, the rotating shaft 22, the swing rod 27, the connecting component 23, the rotation positioning component 25, the force-applying component 24, the workbench 21 and the angle limit component 26 inside, and a lower box body 52 is arranged below the supporting plate 4, and the lower box body 52 encloses the lifting component 3 and the second driving member 28 inside; the upper box body 51 and the lower box body 52 are assembled to form a complete installation box 5, and the simulation test is carried out inside the installation box 5 to avoid the splashing of debris generated by the impact during the test, thereby improving the safety and practicality of the impact simulation device.

[0053] This embodiment also provides a crash test method, using the crash simulation device described above, comprising the following steps:

[0054] S1. Fix the product under test on the swing rod 27. Specifically, the staff fixes the product under test on the swing rod 27 near the end to simulate the situation where the user wears the electronic product on the wrist.

[0055] S2. Rotate the fork 231 to adjust the angle between the product under test and the impact platform 1, move the product under test to the test height, and rotate the swing rod 27 to align the designated position of the product under test with the impact platform 1. Specifically, the staff activates the second drive member 28. The piston rod of the second drive member 28 pushes the fork 231 upward, causing the swing rod 27 to rotate about the rotation axis 22 and lift the product under test to the test height. The staff then rotates the swing rod 27 and rotates the fork 231 about the vertical axis 232, aligning the product under test with the impact platform 1 at the designated angle and designated collision position.

[0056] S3. Release the swing lever 27. Specifically, the staff activates the first driving member 6, which drives the impact platform 1 to rotate. Then, the staff controls the piston rod of the second driving member 28 to quickly retract. Then, under the action of gravity, the swing lever 27 rotates downward around the rotating shaft 22, and drives the product under test to finally collide with the impact platform 1.

[0057] Furthermore, after the product under test collides with the impact platform 1 , the piston rod of the second driving member 28 will quickly extend again and push the shaft fork 231 upward to prevent the rotating impact platform 1 from causing continuous damage to the product under test and the swing rod 27 .

[0058] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
