Description

Technical Field

[0002] The current tire puncture alarm uses an air pressure sensor for feedback and reminders, and cannot provide immediate signal feedback when the tire is punctured. The detection method of obtaining a short-circuit signal by pasting two mutually insulated conductive layers on the inner wall of the tire can provide feedback on the puncture signal after the two conductive layers are punctured to generate a short-circuit signal. However, this signal feedback detection mode has the problem of underreporting, and still needs to be optimized after simulation testing. When conducting simulation tests, the cost of directly using the tire test method is high, and the clamping and disassembly is time-consuming and labor-intensive. Summary of the invention

[0005] The leak feedback mechanism consists of a first conductive layer, a second conductive layer, an insulating layer, an adhesive layer, a control module and a signal transmission module. The first conductive layer and the second conductive layer are fixedly bonded to the upper and lower sides of the insulating layer, the adhesive layer is fixedly bonded to the bottom surface of the second conductive layer, and the adhesive layer is also bonded to the top surface of the rubber pad.

The base 1, the carrier plate 2 and the top plate 12 are respectively fixedly mounted on the bottom, middle and top of the support column 11, the cylinder body of the first telescopic cylinder 33 is fixedly mounted on the top plate 12, the first guide rod 32 is fixedly mounted on both sides of the test box 3, the upper end of the first guide rod 32 is slidably mounted on the top plate 12, and the piston rod of the first telescopic cylinder 33 is fixedly connected to the center position of the top of the test box 3. Then, the top of the test box 3 is provided with an inflation and exhaust interface 31, the bottom of the test box 3 is set as an open structure, the carrier 4 is fixedly mounted on the carrier plate 2, and the middle of the carrier 4 has a through hole, the cylinder seat 51 is fixedly mounted on the bottom of the carrier plate 2, the cylinder body of the second telescopic cylinder 5 is fixedly mounted on the cylinder seat 51, the second guide rod 55 is slidably mounted on the carrier plate 2, the push plate 52 is fixedly mounted on the top of the second guide rod 55, the piston rod of the second telescopic cylinder 5 is fixedly connected to the push plate 52, the clamp 53 is fixedly mounted on the top surface of the push plate 52, the puncture nail 54 is fixedly mounted in the clamp 53, the push plate 52 is located in the middle through hole of the carrier 4, and the rubber pad 9 can be sealed and pressed and fixed between the test box 3 and the carrier 4;

[0016] The leak feedback mechanism is composed of a first conductive layer 71, a second conductive layer 72, an insulating layer 73, an adhesive layer 8, a control module and a signal transmission module. The first conductive layer 71 and the second conductive layer 72 are fixedly bonded to the upper and lower sides of the insulating layer 73, the adhesive layer 8 is fixedly bonded to the bottom surface of the second conductive layer 72, and the adhesive layer 8 is also bonded to the top surface of the rubber pad 9. The first conductive layer 71 is connected to the power supply module through a circuit, and the second conductive layer 72 is connected to the current detection module through a circuit. The power supply module, the current detection module and the signal transmission module are respectively connected to the control module through circuits. A signal receiving module and a sound / light alarm device are arranged outside the test box 3, and the signal receiving module is circuit-connected to the sound / light alarm device.

[0017] It also includes a pre-positioning mechanism, which consists of a screw rod 6, a pressure plate 61, a nut 62 and a spring 63. The screw rod 6 is slidably installed on the top flange of the carrier 4 in a circular array. Four screw rods 6 are arranged in a circular array. The nut 62 is threadedly installed at the lower end of the screw rod 6. The spring 63 is sleeved and installed on the screw rod 6. The upper and lower ends of the spring 63 act on the top flange of the carrier 4 and the nut 62 respectively. The pressure plate 61 is fixedly installed on the top of the screw rod 6. A pull ring 64 is fixedly installed on the top of the pressure plate 61. The screw rod 6 is pulled upward by the pull ring 64 to overcome the elastic force of the spring 63. When the rubber pad 9 is placed between the pressure plate 61 and the carrier 4, the upward pulling force on the screw rod 6 is released. Under the action of the spring 63, the rubber pad 9 is pressed and pre-positioned between the pressure plate 61 and the carrier 4, so that single-person operation can be achieved.

[0018] Since the top plate 12 is relatively thin and has poor guiding performance for the first guide rod 32 , a guide sleeve 10 is fixedly mounted on the top plate 12 , and the first guide rod 32 is slidably mounted in the guide sleeve 10 , which can improve the straightness of the first guide rod 32 when it moves up and down.

The first telescopic cylinder 33 is started to push the test box 3 to move downward, and the rubber pad 9 is sealed and pressed and fixed between the test box 3 and the carrier 4. The inflation and exhaust interface 31 is connected to the air pressure station, and the test box 3 is inflated through the inflation and exhaust interface 31 to simulate the tire pressure. The second telescopic cylinder 5 is started to push the push plate to move upward. After the puncture nail 54 pierces the rubber pad 9, the first conductive layer 71, the second conductive layer 72, the insulating layer 73, and the adhesive layer 8, the first conductive layer 71 and the second conductive layer 72 are in a circuit connection state at the iron puncture nail 54. The current detection module sends an electrical signal to the control module, and the signal transmission module sends the signal to the signal receiving module. Feedback reminders are given through the sound / light alarm device. If the sound / light alarm device does not give feedback reminders after the puncture nail 54 passes through the first conductive layer 71, then there are practical problems in the design structure of the leak feedback mechanism of this structure, which needs to be optimized and improved.
