[0031] See also Figure 1 The utility model provides a detection device 100 for detecting the tone of a car horn, comprising a switch component, a sampling component 1 and a central control platform. The sampling component 1 comprises a first bracket 11, a second bracket 12 rotatably mounted on the first bracket 11 and a sound receiver 13 mounted on the second bracket 12. The switch component and the sound receiver 13 are both connected to the central control platform signal. The sound receiver 13 is used to receive the sound emitted by the car horn. The switch component is used to control the start and stop of the sound receiver 13. The central control platform is used to analyze whether the sound emitted by the car horn is qualified. Specifically, the normal tone of the car horn is now recorded in the central control platform, and then the operator drives the car to the measuring runway. The car is now conducting various tests on the measuring runway. When the car drives to the exit of the measuring runway, the operator presses the switch component, and then presses the horn button in the car to make the horn sound. The sound receiver 13 will receive the sound emitted by the horn. The sound receiver 13 transmits the received sound to the central control platform, and then the central control platform will analyze whether the sound emitted by the horn has defects such as hoarseness, gurgling, sound stratification and timbre change; after the sound receiver 13 receives the sound, it transmits the sound to the central control platform. The timbre of the sound received by the sound receiver 13 is then compared with the timbre of the normal car horn stored in the central control platform. If they are basically the same, it indicates that the operator has driven the car to a qualified position without any defects; if there is a big difference, it indicates that there is a defect and the horn needs to be adjusted or replaced again to make the horn meet the requirements; through such a structure, there is no need for the operator to judge the quality of the horn by his own hearing, and there will be no situation where the quality is different due to different evaluation standards of different operators; this greatly improves the accuracy and consistency of the detection and improves the qualified rate of factory products.

[0032] See also Figures 2 to 4In one embodiment, a spherical groove 111 is provided at one end of the first bracket 11, and a connecting ball head 121 is provided at one end of the second bracket 12, and the connecting ball head 121 is rotatably installed in the spherical groove 111. Specifically, the sound receiver 13 is installed in the second bracket 12, and the connecting ball head 121 is clamped in the spherical groove 111. The connecting ball head 121 can rotate 360 ​​degrees in the spherical groove 111. When the operator rotates the connecting ball head 121 through the second bracket 12, a certain angle will be formed between the second bracket 12 and the first bracket 11, and the receiving end of the sound receiver 13 will face the car. In this way, when the car horn makes a sound, the receiving end of the sound receiver 13 faces the car, which can more easily and accurately obtain the sound when the car horn makes a sound, and can further improve the accuracy of detection.

[0033] See also Figure 4 In one embodiment, two spaced-apart protrusions 122 are formed at one end of the second bracket 12 away from the first bracket 11, and an open groove 123 is formed between the two protrusions 122. The second bracket 12 is also formed with a mounting hole 124, which is communicated with the open groove 123. The two protrusions 122 are both formed with locking holes 122a. The detection device 100 also includes a locking member 2, and the sound receiver 13 is installed in the mounting hole 124. The two ends of the locking member 2 are respectively installed in the two locking holes 122a so that the two protrusions 122 are close to each other. Specifically, when installing the sound receiver 13, the operator first inserts the installation end of the sound receiver 13 into the installation hole 124, and then the operator respectively installs the two ends of the locking member 2 on the two locking holes 122a of the two protrusions 122, so that the two protrusions 122 are close to each other, and the open groove 123 between the two protrusions 122 becomes smaller, so that the inner wall of the installation hole 124 abuts against the outer wall of the sound receiver 13, so that the sound receiver 13 can be fixed in the installation hole 124. Through such an arrangement, the sound receiver 13 can be firmly fixed, and through such an arrangement, installation or disassembly is relatively simple and convenient.

[0034] See also Figure 4In one embodiment, both protrusions 122 are elastic protrusions 122. Specifically, when installing the sound receiver 13, the operator first inserts the installation end of the sound receiver 13 into the installation hole 124, and then the operator installs the two ends of the locking member 2 on the two locking holes 122a of the two elastic protrusions 122, so that the two elastic protrusions 122 are close to each other and produce elastic deformation, and the opening groove 123 between the two elastic protrusions 122 becomes smaller, so that the inner wall of the installation hole 124 abuts against the outer wall of the sound receiver 13, so that the sound receiver 13 can be fixed in the installation hole 124. When the operator needs to disassemble the sound receiver 13 When the locking member 2 is in the state of being pressed against the locking hole 124, the operator only needs to remove the two ends of the locking member 2 from the two locking holes 122a respectively, so that the two elastic protrusions 122 that were originally close to each other will restore their deformation due to the elastic force, and the two elastic protrusions 122 will separate from each other and return to their original positions, and the inner wall of the mounting hole 124 will not abut against the sound receiver 13, so that the sound receiver 13 can be taken out from the mounting hole 124; by providing the elastic protrusion 122, the situation that the protrusion 122 cannot return to its original position after being squeezed, resulting in the sound receiver 13 being unable to be removed from the mounting hole 124, will not occur.

Specifically, when the elastic plate 126 needs to be replaced, the operator rotates the elastic plate 126, so that the external thread of the rotating rod 125 will be disengaged from the threaded hole of the elastic plate 126; when the elastic plate 126 needs to be installed, the operator rotates the elastic plate 126 in the opposite direction, so that the external thread of the rotating rod 125 will be locked in the threaded hole of the elastic plate 126; through such a setting, the elastic plate 126 can be quickly installed and removed.

When the position of the sound receiver 13 is too high to accurately receive the sound emitted by the horn, the operator first removes the two fixing parts 3, and then extends the first connecting rod 112 or the second connecting rod 113 according to the height, or extends the first connecting rod 112 and the second connecting rod 113 at the same time. After extending to a certain length, the first connecting rod 112, the second connecting rod 113 and the third connecting rod 114 are locked with each other, so that the sound receiver 13 on the second bracket 12 can be closer to the car, so that the sound signal emitted by the horn can be received at a closer distance. Through such a structure, the length of the first bracket 11 can be adjusted according to different types of cars, so that the sound receiver 13 can receive sound close to cars of various types and heights.
