[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0032] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0033] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-6 A comprehensive performance testing device for alarm devices, comprising a base 1;

[0034] The base 1 is equipped with an impact sensitivity testing mechanism 2 for adjusting the magnitude of simulated impact force and testing the sensitivity of the collision alarm.

[0035] The base 1 is equipped with an impact material replacement mechanism 3 for self-replacing the impact material;

[0036] like Figure 2 As shown, the impact sensitivity testing mechanism 2 includes a collision simulation component 21, a power storage component 22, a rotating rod limiting component 23, and a collision force adjustment component 24; the base 1, the power storage component 22, the rotating rod limiting component 23, and the collision force adjustment component 24 are all connected to the collision simulation component 21; the power storage component 22 and the rotating rod limiting component 23 are both connected to the base 1; the collision simulation component 21 is used to simulate the force of a collision, the power storage component 22 is used to store power in the collision simulation component 21 and adjust the impact force; the rotating rod limiting component 23 is used to limit the collision simulation component 21, and the collision force adjustment component 24 is used to place an alarm and adjust the impact force range;

[0037] In this invention, the operator installs the collision alarm to be tested inside the collision force adjustment component 24 and adjusts the collision force range to be tested using the collision force adjustment component 24. Then, the force storage component 22 stores the impact force of the collision simulation component 21 as needed. Under the limit of the rotating rod limiting component 23, the collision simulation component 21 impacts the collision alarm with the impact material replacement mechanism 3 to test the reliability of the collision alarm at various force ranges. When the collision material needs to be changed, the impact material replacement mechanism 3 automatically changes the collision material, thereby simulating the sensitivity and reliability of the collision alarm when it collides with objects of different materials.

[0038] The collision simulation component 21 includes a rotating rod 211 and a rotating frame 212; the lower end of the rotating frame 212 is fixedly connected to the left end of the base 1, the rotating rod 211 is rotatably connected to the rotating frame 212 via a rotating shaft, and the energy storage component 22, the rotating rod limiting component 23, and the collision force adjustment component 24 are all connected to the rotating rod 211; the energy storage component 22 is connected to the rotating frame 212.

[0039] The energy storage component 22 includes an energy storage drive component and an energy storage limit and avoidance component; the base 1, the rotating rod 211 and the rotating frame 212 are all connected to the energy storage drive component; the rotating rod 211 and the energy storage drive component are all connected to the energy storage limit and avoidance component;

[0040] The power storage drive assembly includes an electric cylinder 221, a support frame 224, and a dial 225; the lower end of the support frame 224 is fixedly connected to the left end of the base 1, the support frame 224 is located on the left side of the rotating frame 212, the support frame 224 is fixedly connected to the electric cylinder 221, and the electric cylinder 221 is connected to the power storage limit and avoidance assembly; the dial 225 is fixedly installed on the front side of the rotating frame 212.

[0041] The power storage and limiting avoidance assembly includes a pressure block 222 and a cylinder 226; a limiting groove 223 is provided at the left end of the rotating rod 211; the pressure block 222 is slidably connected to the rotating rod 211 through the limiting groove 223, and the pressure block 222 is fixedly connected to the driving end of the cylinder 226; the cylinder 226 is fixedly connected to the driving end of the electric push cylinder 221.

[0042] The rotating rod limiting assembly 23 includes a limiting frame 231; the lower end of the limiting frame 231 is fixedly connected to the base 1, the limiting frame 231 is located on the right side of the rotating rod 211, and a limiting groove 232 is provided on the limiting frame 231. The rotating rod 211 is slidably connected to the limiting frame 231 through the limiting groove 232. The limiting groove 232 is used to limit the rotating rod 211 when it rotates.

[0043] The collision force adjustment component 24 includes a positioning pin 241 and an alarm placement box 244; the right end of the rotating rod 211 is provided with a plurality of force adjustment holes 242 at equal intervals; the alarm placement box 244 is provided with a positioning hole 243; the positioning pin 241 is inserted into the force adjustment hole 242 and the positioning hole 243.

[0044] In this invention, the operator installs the alarm in the alarm placement box 244, and then inserts the positioning pin 241 into the positioning hole 243 and the corresponding force adjustment hole 242 to fix the position of the alarm placement box 244. When the positioning pin 241 is inserted into the force adjustment hole 242 closer to the right end of the rotating rod 211, the impact force provided by the simulated impact at the same rotation angle of the rotating rod 211 is greater. The electric push cylinder 221 is activated, which drives the pressure block 222 to press down the left end of the rotating rod 211 through the cylinder 226, thus pressing down the right end of the rotating rod 211. The lever 222 is lifted and slids within the limiting groove 232. At this time, the pressure block 222 is slidably connected to the rotating rod 211 within the limiting groove 223. The reading on the dial 225 is observed. When the reading matches the predetermined value, the electric push cylinder 221 stops driving the rotating rod 211 to move. Then, the cylinder 226 drives the pressure block 222 to slide out of the limiting groove 223, canceling the limitation on the left end of the rotating rod 211. This causes the alarm placement box 244 at the right end of the rotating rod 211 to fall downwards, thus achieving a test of the reliability of the collision alarm at various force ranges.

[0047] The material replacement component 32 includes an impact material block 321 and a rotating frame 322. Multiple impact material blocks 321 are arranged in a circular array on the right side of the base 1. All impact material blocks 321 are fixedly connected to the rotating frame 322. The rotating frame 322 is fixedly connected to the rotating shaft 312. The lower end of the impact material block 321 is slidably connected to the base 1.

[0048] In this utility model, when the operator needs to change the impact material, the servo motor 311 is started. The servo motor 311 drives the rotating frame 322 to rotate at the upper end of the base 1 through the rotating shaft 312. The rotating frame 322 rotates and rotates the impact material block 321 of the required material to the lower part of the alarm placement box 244; thus completing the self-replacement of the impact material.

[0049] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
