[0002] Audio is a professional term. The term audio has been used to generally describe the equipment and functions related to sound within the audio range. All sounds that humans can hear are called audio, which may include noise, etc. Video generally refers to various technologies that capture, record, process, store, transmit and reproduce a series of static images in the form of electrical signals. During the manufacturing process, audio and video equipment needs to be subjected to a series of tests to ensure product quality.

[0003] The impact test is one of the testing processes. The existing impact test is a destructive test, which usually tests whether the crash resistance and collision compatibility of various vehicles or related systems and components meet the safety design standards. The impact test requires a mandatory pressure test on the body parts, such as the audio housing and display screen. However, during the test, the test object is placed on the test table and hit by the impact plate. The test object will vibrate due to the impact force. If there is no shock absorption treatment during the test, the test table will be worn, and long-term testing will reduce the life of the equipment.

[0004] Therefore, it is necessary to design an audio and video impact test device to solve the above technical problems. Utility Model Content

[0026] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0027] Embodiment: An audio and video impact test device, such as Figure 1-Figure 6As shown, it includes a test bench 1, a controller 2, an impact plate 7, a cylinder 11, a T-bar 12, a receiving plate 101, a damper 102 and a first elastic member 103. The controller 2 is installed on the left side of the middle of the test bench 1 by screws, the impact plate 7 is slidably connected to the upper part of the test bench 1, the cylinder 11 is installed on the front side of the top of the test bench 1 by screws, the cylinder 11 is electrically connected to the controller 2, the T-bar 12 is connected to the telescopic rod of the cylinder 11 by welding, and the end of the T-bar 12 away from the cylinder 11 is clamped with the bottom surface of the impact plate 7, the receiving plate 101 is slidably connected to the lower part of the test bench 1, the receiving plate 101 is made of wear-resistant and pressure-resistant material, a plurality of dampers 102 are installed between the test bench 1 and the receiving plate 101, and a plurality of the first elastic members 103 are connected between the test bench 1 and the receiving plate 101. 3. The first elastic member 103 is a buffer spring, and each of the first elastic members 103 is wound around the corresponding damper 102.

[0028] like Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 7 As shown, it also includes a weight-increasing plate 8 and a latch 9. A plurality of the weight-increasing plates 8 are stacked on top of the impact plate 7. Each of the weight-increasing plates 8 is symmetrically provided with a clamping hole 10 on both sides thereof, and a latch 9 is slidably placed in each of the clamping holes 10. Each of the latching holes 10 passes through the upper part of the test bench 1.

[0029] like Figure 6 As shown, it also includes a limiting block 13 and a second elastic member 14. Each of the weight-increasing plates 8 is provided with a slot on both the front and rear sides. The front and rear sides of the impact plate 7 are symmetrically slidably and rotatably connected to the limiting block 13. The four limiting blocks 13 are all engaged with the slots of the weight-increasing plates 8. The second elastic member 14 is connected between the four limiting blocks 13 and the impact plate 7. The second elastic member 14 is a compression spring.

[0030] When the device is needed, the object to be tested is placed on the receiving plate 101, and then the staff starts the cylinder 11 through the controller 2. The telescopic rod of the cylinder 11 extends to push the T-shaped rod 12 forward. When the T-shaped rod 12 is separated from the impact plate 7, the impact plate 7 falls directly downward by its own gravity and hits the object to be tested. After hitting the object to be tested, the staff observes the impact degree of the object to be tested and can measure its mass. When hitting the object to be tested, the damper 102 and the first elastic member 103 cooperate to buffer the object to be tested on the receiving plate 101 to prevent the receiving plate 101 from being scrapped due to a major impact. After the test is completed, the impact plate 7 is lifted up to its original position. Then the staff controls the cylinder 11 through the controller 2 to retract the telescopic rod of the cylinder 11 to drive the T-shaped rod 12 to move backward to its original position and engage with the bottom surface of the impact plate 7 to prevent the impact plate 7 from falling down. Finally, the receiving plate 101 is lifted up to its original position. 1, and repeat the above operation to test again. If you need to increase or decrease the impact force during the test, you can adjust it by increasing or decreasing the number of weight-added plates 8. After the number of weight-added plates 8 is determined, insert the latch 9 into the corresponding card hole 10 on the weight-added plate 8. Then, when the impact plate 7 falls, the weight-added plate 8 inserted with the latch 9 and the weight-added plates 8 above will not fall with it. To ensure that the weight-added plate 8 will not separate from the impact plate 7 when it falls, the staff can pull the limit block 13 upwards. At this time, the second elastic member 14 is squeezed and deformed, and then the limit block 13 is rotated clockwise to the topmost weight-added plate 8 card slot of the impact plate 7. Release the limit block 13, and the limit block 13 will move downward through the force of the second elastic member 14 to press the weight-added plate 8 and the impact plate 7 together. Then, when falling, the weight-added plate 8 and the impact plate 7 will not separate. If you need to adjust the number of weight-added plates 8, move the limit block 1 3 is rotated counterclockwise to disengage the slot of the weight-increasing plate 8, and the limit block 13 is reset and moved downward to the original position through the second elastic member 14, and then the latch 9 is pulled outward to disengage the slot 10 of the weight-increasing plate 8, and the number of weight-increasing plates 8 can be adjusted to adjust the impact force.

[0031] like Figure 1-Figure 7 As shown, it also includes a motor 3, a bidirectional screw 4, a guide rod 5 and a clamping rod 6. The motor 3 is installed on the right side of the lower part of the test bench 1 by screws, and the motor 3 is electrically connected to the controller 2. The output shaft of the motor 3 is connected to the bidirectional screw 4 by welding. The bidirectional screw 4 is rotatably connected to the front side of the lower part of the test bench 1, and the guide rod 5 is connected to the rear side of the lower part of the test bench 1 by welding. The clamping rod 6 is symmetrically connected between the guide rod 5 and the bidirectional screw 4. The two clamping rods 6 are both located above the receiving plate 101, and the two clamping rods 6 are slidably connected to the guide rod 5, and the two clamping rods 6 are threadedly connected to the bidirectional screw 4.

[0032] To prevent the object to be tested from moving at will during the inspection, the staff can start the motor 3 through the controller 2 after placing the object to be tested on the receiving plate 10 1. The output shaft of the motor 3 drives the bidirectional screw 4 to rotate clockwise, and the clamping rods 6 on both sides move toward each other along the guide rod 5 until the object to be tested is clamped. The motor 3 can be turned off through the controller 2. When the inspection of the object to be tested is completed, the staff can start the motor 3 through the controller 2 again. The output shaft of the motor 3 drives the bidirectional screw 4 to rotate counterclockwise, and the clamping rods 6 on both sides move toward each other along the guide rod 5 until they are separated from the object to be tested. At this time, the receiving plate 10 1 can be taken out.
