[0024] Please refer to Figures 1-6 , an audio-visual equipment detection device, including a drop table 1 and a detection mechanism 2 arranged on one side of its top. Protection mechanisms 3 are correspondingly arranged on the front and back sides of the drop table 1, and an auxiliary blocking mechanism 4 is arranged on the side of the top of the drop table 1 away from the detection mechanism 2:

[0025] The drop table 1 is the basic platform of the entire detection device, used to carry the audio-visual equipment to be tested and provide a fixed drop point. The design of the drop table 1 should consider strength and stability to ensure that it will not move or deform due to the impact of the equipment during the test.

[0026] Furthermore, the protection mechanism 3 includes a protection shell 301 fixed to the top of the drop table 1. A protection plate 302 is slidably connected inside the protection shell 301. One end inner wall of the protection plate 302 is threadedly connected with a threaded rod 304. The bottom of the threaded rod 304 is rotatably connected to the top of the drop table 1. A first bevel gear 305 is fixedly sleeved on the lower surface of the threaded rod 304. A second bevel gear 306 is meshed and connected to one side of the first bevel gear 305. The inner walls of the second bevel gear 306 are respectively fixedly connected with a first rotating rod 307 and a second rotating rod 308. One ends of the first rotating rod 307 and the second rotating rod 308 extend outside the protection shell 301 and are rotatably connected thereto.

[0027] The detection mechanism 2 is located on one side of the drop table 1. Its function is to immediately collect and analyze relevant data such as acceleration, impact force, and device status after the device drops, so as to evaluate the anti-drop performance of the audio-video device. The protection mechanism 3 is to prevent the device under test from flying out of the detection area during the dropping process, causing potential safety hazards or affecting the accuracy of the test results. By transmitting and converting the rotation direction through the first bevel gear 305 and the second bevel gear 306, the rotation of the first rotating rod 307 and the second rotating rod 308 is transmitted to the threaded rod 304 to realize the lifting of the protection plate 302. The auxiliary blocking mechanism 4 is arranged on the side of the drop table 1 away from the detection mechanism 2. Its function is to further prevent the device from moving laterally during the dropping process, ensure that the device can fall within the predetermined detection area, improve the accuracy and repeatability of the test. This device realizes the protection and blocking functions through a fine mechanical structure, ensuring the safety and effectiveness of the drop test of the audio-video device. By adjusting the position of the protection plate 302, it can adapt to different sizes of devices under test, improving the versatility and flexibility of the device. At the same time, through the transmission system of the first bevel gear 305 and the second bevel gear 306, the stable lifting of the protection plate 302 is realized, reducing the operation difficulty and improving the test efficiency.

[0028] Further, the detection mechanism 2 includes a U-shaped seat 201 fixedly arranged on one side of the top of the drop table 1. A lifting block 202 is slidably connected inside the U-shaped seat 201. A first electric push rod 203 is fixedly connected to the bottom of the inner wall of the U-shaped seat 201. The telescopic end of the first electric push rod 203 is fixedly connected to the bottom of the lifting block 202. A guide rod 204 is slidably connected to the inner wall of the lifting block 202, and the guide rod 204 is fixedly arranged inside the U-shaped seat 201.

[0029] The lifting block 202 is a component that slides up and down inside the U-shaped seat 201 through the first electric push rod 203.

[0030] Further, a mounting plate 205 is fixedly connected to one side of the lifting block 202. A bidirectional lead screw 206 is rotatably connected to one side of the mounting plate 205. One end of the bidirectional lead screw 206 extends outside the mounting plate 205 and is fixedly connected to a first motor 207, and the first motor 207 is fixedly arranged on one side of the mounting plate 205.

[0031] The first motor 207 drives the bidirectional lead screw 206 to rotate. By rotating the bidirectional lead screw 206 forward and backward, two clamping plates 208 in opposite directions can be driven to move horizontally, realizing the clamping and positioning of the audio-video device, ensuring the accurate position of the device during the drop test.

[0032] Further, clamping plates 208 are threadedly connected to the left and right sides of the surface of the bidirectional lead screw 206.

[0033] The inner wall of the clamping plate 208 is slidably connected to the limiting rod 209, and the limiting rod 209 is fixed on the mounting plate 205, ensuring that the clamping plate 208 moves in a straight line and avoiding any lateral displacement caused by the rotation of the bidirectional lead screw 206, guaranteeing the stability and precision of the equipment clamping.

[0034] Further, a second motor 309 is fixedly connected to one end of the first rotating rod 307. The second motor 309 is fixedly arranged on the top of the dropping table 1. First belt pulleys 310 and second belt pulleys 311 are respectively fixedly sleeved on the surfaces of the first rotating rod 307 and the second rotating rod 308, and a belt 312 is drivingly connected between the first belt pulley 310 and the second belt pulley 311.

[0035] The second motor 309 is fixed on the top of the dropping table 1 and is used to drive the rotation of the first rotating rod 307. When the second motor 309 drives the rotation of the first rotating rod 307, through the transmission of the belt 312, the second rotating rod 308 also rotates accordingly, thereby realizing the power transmission between the first bevel gear 305 and the second bevel gear 306, and finally controlling the rotation of the threaded rod 304 to achieve the purpose of lifting the protective plate 302.

[0036] Further, a limiting block 303 is fixedly connected to the surface of the protective plate 302, and a limiting groove is formed in the inner wall of the protective shell 301. The limiting block 303 is slidably connected to the limiting groove.

[0037] Through the sliding of the limiting block 303 in the limiting groove, the protective plate 302 can be lifted and lowered in a straight line, avoiding any possible deflection caused by the rotation of the threaded rod 304 and ensuring that the movement track of the protective plate 302 meets the design requirements.

[0038] Further, the auxiliary blocking mechanism 4 includes a first baffle 401 rotatably arranged on the top of the dropping table 1. A second electric push rod 402 is rotatably connected to one side of the first baffle 401, and the second electric push rod 402 is rotatably arranged on the top of the dropping table 1.

By changing the angle of the first baffle 401, it is possible to adapt to test devices of different sizes and shapes, ensuring the effectiveness of the blocking. The use of the second electric push rod 402 makes the adjustment of the first baffle 401 more flexible and precise.

[0040] Further, a third electric push rod 403 is fixedly connected to the inner wall of the first baffle 401, and a second baffle 404 is fixedly connected to the telescopic end of the third electric push rod 403.

[0041] The third electric push rod 403 is connected to the second baffle 404. By controlling the expansion and contraction of the third electric push rod 403, the position of the second baffle 404 can be adjusted to achieve adaptive blocking of devices of different sizes. This design enables the auxiliary blocking mechanism 4 to meet more diverse test requirements and improves the flexibility and efficiency of the test.
