Description

Technical Field

[0001] This utility model relates to the field of buzzer detection technology, specifically a detection device for vehicle instrument buzzers. Background Technology

[0002] Most cars have buzzers in their instrument panels, which emit different audio signals according to the instrument panel's prompts and alarm functions. During the production and assembly of cars, the buzzers in the instrument panels need to be tested. During testing, the buzzer's pins are usually inserted into the test holes, and the buzzer is powered on to test whether it is working properly.

[0003] The detection holes of current detection devices lack protective measures. When not in use, the detection holes are directly exposed to the outside, making them prone to dust entering and causing poor contact during detection, which can affect the accuracy of the buzzer. Therefore, we have proposed a detection device for vehicle instrument buzzers. Utility Model Content

[0019] 2. The detection device for the vehicle instrument buzzer utilizes a support rod, mounting block, and clamping mechanism. After placing the buzzer in the placement slot, rotating the knob drives the bidirectional threaded rod to rotate. The cooperation of the limiting block and the limiting slot causes the moving rod to move closer together, which in turn causes the clamping plates to move closer together, thereby clamping the buzzer. This prevents the buzzer from vibrating too much when it sounds, which could lead to poor contact between the pin and the detection hole, thus ensuring stable detection. Attached Figure Description

[0028] This utility model provides a detection device for vehicle instrument buzzers, preventing dust from entering the detection hole, thus preventing poor contact and ensuring the accuracy of the detection. Please refer to [link / reference]. Figure 1-4 It includes a detection device body 100, a controller 200, and a power interface 300;

[0029] Please refer to it again. Figure 1 The front center of the detection device body 100 is embedded with a controller 200. The right center of the detection device body 100 is provided with a power interface 300. The top center of the detection device body 100 is provided with a placement slot 110. The bottom of the placement slot 110 is symmetrically provided with detection holes 120. The rear center of the top of the detection device body 100 is fixedly connected with a connecting seat 400. The front center of the detection device body 100 is fixedly connected with a mounting box 410. The top of the detection device body 100 is provided with a protective mechanism.

[0030] Please refer to it again. Figure 1 The top of the detection device body 100 is symmetrically and fixedly connected with support rods 500, and the top of the support rods 500 is fixedly connected with mounting blocks 510. The mounting blocks 510 are equipped with clamping mechanisms inside.

[0031] Please refer to it again. Figure 3 The protective mechanism includes a return spring 420, a connecting plate 430, a plug rod 440, a pull plate 450, a moving groove 460, a connecting block 470, a protective plate 480, a plug hole 481, and a sealing gasket 490.

[0032] Please refer to it again. Figure 3 A reset spring 420 is fixedly connected to the middle of the front side of the inner cavity of the mounting box 410. A connecting plate 430 is fixedly connected to the other end of the reset spring 420. A plug rod 440 is fixedly connected to the middle of the rear side of the connecting plate 430.

[0033] Please refer to it again. Figure 3 A pull plate 450 is fixedly connected to the top center of the connecting plate 430. A moving groove 460 is opened through the top center of the mounting box 410. A connecting block 470 is rotatably connected inside the connecting seat 400. A protective plate 480 is fixedly connected to the front side of the connecting block 470. An insertion hole 481 is opened on the front side of the outer wall of the protective plate 480. A sealing gasket 490 is fixedly connected to the bottom center of the protective plate 480.

[0034] In summary, by utilizing the connector 400, mounting box 410, and protective mechanism, when not in use, pulling the pull plate 450 moves the connecting plate 430, causing the insertion rod 440 to retract into the mounting box 410, compressing the return spring 420. Then, rotating the protective plate 480 positions the sealing gasket 490 in the placement groove 110. Loosening the pull plate 450 and resetting the return spring 420 causes the connecting plate 430 to move the insertion rod 440 back to its original position in the insertion hole 481, thus fixing the protective plate 480 and shielding the placement groove 110. This prevents dust from entering the detection hole 120, thus preventing poor contact and ensuring the accuracy of the detection.

[0035] Please refer to it again. Figure 3 The connecting plate 430 is slidably connected to the inside of the mounting box 410, and the outer side wall of the connecting plate 430 is in contact with the inner side wall of the mounting box 410.

[0036] Please refer to it again. Figure 3 The pull plate 450 is slidably connected to the inside of the moving groove 460, and the diameter of the sealing gasket 490 is equal to that of the placement groove 110.

[0037] Please refer to it again. Figure 4The clamping mechanism includes a mounting groove 520, a limiting groove 530, a bidirectional threaded rod 540, a knob 550, a moving rod 560, a limiting block 570, and a clamping plate 580. The mounting block 510 has a mounting groove 520 through the top center. The mounting groove 520 has a limiting groove 530 in the middle of the front and rear sides. The bidirectional threaded rod 540 is rotatably connected through the middle between the left and right sides of the mounting groove 520. The knob 550 is fixedly connected to both ends of the bidirectional threaded rod 540. The moving rod 560 is symmetrically threaded to the outer wall of the bidirectional threaded rod 540. The limiting block 570 is fixedly connected to the top of the front and rear sides of the moving rod 560. The clamping plate 580 is fixedly connected to the bottom end of the moving rod 560.

[0038] Please refer to it again. Figure 4 The limiting block 570 is slidably connected to the inside of the limiting groove 530, and rubber pads are glued to the opposite sides of the left and right clamps 580.

[0039] In summary, by utilizing the support rod 500, mounting block 510, and clamping mechanism, after placing the buzzer in the placement slot 110, rotating the knob 550 drives the bidirectional threaded rod 540 to rotate. The cooperation of the limiting block 570 and the limiting slot 530 causes the moving rods 560 to move closer together, which in turn causes the clamping plates 580 to move closer together, thus clamping the buzzer and preventing excessive vibration of the buzzer during sounding, which could lead to poor contact between the pins and the detection hole 120, ensuring stable detection.

[0040] In practical use, when performing testing, those skilled in the art insert the buzzer's pins into the test hole 120, positioning the buzzer inside the placement slot 110. Rotating the knob 550 causes the bidirectional threaded rod 540 to rotate. Utilizing the cooperation of the limiting block 570 and the limiting slot 530, the moving rods 560 move closer together, causing the clamping plates 580 to move closer together, thereby clamping the buzzer. The controller 200 controls the current to be turned on for testing of the buzzer. When not in use... When the pull plate 450 is pulled, the connecting plate 430 is moved, causing the insertion rod 440 to retract into the mounting box 410, which compresses the reset spring 420. Then, the protective plate 480 is rotated so that the sealing gasket 490 is located in the placement groove 110. The pull plate 450 is then loosened, and the reset spring 420 resets the connecting plate 430, causing the insertion rod 440 to reset and be located in the insertion hole 481. This fixes the protective plate 480, thereby blocking the placement groove 110.
