Description

Technical Field

[0001] This utility model relates to the field of inner tube safety monitoring technology, specifically a gas molecule adsorption type inner tube leak safety early warning device. Background Technology

[0002] As the core load-bearing component of a vehicle, the airtightness of tires is directly related to driving safety and stability. Inner tube leakage is a common tire failure. Initially, a small amount of leakage is difficult to detect, but as the amount of leakage increases, it will lead to a drop in tire pressure, abnormal tire wear, and even tire blowout accidents at high speeds.

[0003] In the prior art, Chinese Patent No. CN222682135U discloses an inner tube for engineering heavy-duty vehicles with a tire pressure monitoring system, including a sensor, an inner tube body, and a valve stem. The sensor is fitted to the inner wall of the inner tube body, and the valve stem is fitted to the outer wall of the inner ring of the inner tube body. The sensor includes an outer protective layer, a sensing unit, a wall-mounted substrate, a signal transmission unit, a circuit board, and a battery. It adopts a built-in wall-mounted tire pressure detection system. The inner tube tire pressure monitoring device also has high reliability and stability. Since the sensor is directly embedded inside the tire, it is not affected by external environmental interference, such as mud, water, or dirt, enabling the device to work stably under various harsh weather and road conditions, providing drivers with continuous and reliable tire pressure monitoring services.

[0004] Based on the above information, existing inner tube leak detection devices monitor macroscopic tire pressure changes and only trigger an alarm when the tire pressure drops to a threshold due to an inner tube leak. They cannot identify initial minor leaks, thus failing to detect and address them in a timely manner. Therefore, we propose a gas molecule adsorption type inner tube leak safety early warning device. Utility Model Content

[0005] The purpose of this invention is to provide a gas molecule adsorption type inner tube leak safety early warning device to solve the problem that the existing inner tube leak monitoring devices mentioned in the background art monitor macroscopic tire pressure changes and only alarm when the tire pressure drops to a threshold due to inner tube leaks. They cannot identify initial micro-leaks and therefore cannot detect and deal with them in time.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a gas molecule adsorption type inner tube leak safety warning device, comprising an outer tire and a device body, wherein an inner tube is disposed inside the outer tire, and the device body is disposed at an equal angle between the outer tire and the inner tube, the device body being composed of an insulating substrate, a gas molecule sensing module, a signal transmission module, and a power supply module, wherein an assembly groove is provided on the inner wall of the outer tire, and a limiting flange is provided on the inner wall of the assembly groove, and a guiding structure for guiding leaked gas is provided at the end of the device body.

[0007] Furthermore, a gas molecule adsorption cavity is formed inside the insulating substrate, and the gas molecule sensing module is located inside the gas molecule adsorption cavity. The gas molecule sensing module and the signal transmission module are electrically connected by wires.

[0008] Furthermore, the signal transmission module is wirelessly connected to the external control module, and both the signal transmission module and the gas molecule sensing module are electrically connected to the power supply module via wires.

[0009] Furthermore, the outer wall of the insulating substrate is provided with uniformly distributed adsorption pores, one end of which is connected to the inside of the outer tire, and the other end of which is connected to the inside of the gas molecule adsorption cavity.

[0010] Furthermore, the assembly groove is adapted to the main body of the device, the outer wall of the main body of the device is provided with an adhesive layer, and the adhesive layer is bonded to the inner wall of the assembly groove. The limiting flange is provided along the side wall of the assembly groove near the opening end, and the outer wall of the limiting flange is in contact with the outer wall of the main body of the device.

[0011] Furthermore, the guiding structure includes a gas molecule guiding tube fixedly installed at the end of the device body, and an air inlet is provided on the outer wall of the gas molecule guiding tube.

[0012] Furthermore, the two ends of the gas molecule guiding tube are respectively connected to the ends of the two sets of device main bodies, and the gas molecule guiding tubes are arranged at equal intervals, and the gas molecule guiding tubes are connected to the gas molecule adsorption cavity.

[0013] Furthermore, the air inlets are evenly distributed on the sidewall of the gas molecule guide tube, and the air inlets on both sides of the gas molecule guide tube are staggered, and the ends of the air inlets are connected to the inside of the outer tire.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This gas molecule adsorption type inner tube leak safety warning device, through the structure of setting up a gas molecule sensing module and a gas molecule adsorption chamber, can directly adsorb and sense leaking gas molecules. With the help of the adsorption holes evenly distributed on the outer wall of the insulating substrate, as well as the gas molecule guide tube and staggered air inlet holes at the end of the main body of the device, it can efficiently capture gas molecules generated by the initial trace leak of the inner tube, realize the monitoring dimension of gas molecule leak warning, and greatly improve the sensitivity of leak detection. It allows the driver to detect the potential inner tube leak before the tire pressure changes significantly, and buys valuable time for timely handling of faults and prevention of accidents.

[0015] 2. The fitting groove on the inner wall of the outer tire, combined with the fitting design of the limiting flange and the outer wall of the device body, and the bonding and fixing of the adhesive layer on the outer wall of the device body to the inner wall of the fitting groove, forms a double fixing structure. This not only ensures that the device body is stably installed at an equal angle between the outer tire and the inner tire, effectively preventing the device from falling out of the preset position due to vibration and displacement during vehicle operation, thus ensuring the continuous stability of the monitoring function; at the same time, the design of the fitting groove and the limiting flange also protects the device body, reducing frictional damage to the device caused by the relative movement of the inner tire and the outer tire, extending the service life of the device, and further improving the reliability of the device under complex road conditions.

[0016] 3. The design of connecting the two ends of the gas molecule guide tube to the ends of the two main units of the device and communicating with the gas molecule adsorption chamber enables the linkage monitoring of multiple main units of the device, expands the coverage of leak detection, and avoids missed detection due to blind spots of a single device; the cooperation between the guide tube and the air inlet can guide the gas inside the tire to flow directionally to the adsorption chamber, improving the adsorption efficiency of gas molecules.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1: Please refer to Figures 1-6 The present invention provides the following technical solution: a gas molecule adsorption type inner tube leak safety warning device, including an outer tire 2 and a device body 1, an inner tube 3 is provided inside the outer tire 2, and the device body 1 is set at an equal angle between the outer tire 2 and the inner tube 3. The device body 1 is composed of an insulating substrate 4, a gas molecule sensing module 404, a signal transmission module 403 and a power module 402. An assembly groove 201 is provided on the inner wall of the outer tire 2, and a limiting flange 202 is provided on the inner wall of the assembly groove 201.

[0021] like Figure 6 As shown, a gas molecule adsorption cavity 5 is formed inside the insulating substrate 4, and the gas molecule sensing module 404 is located inside the gas molecule adsorption cavity 5. The gas molecule sensing module 404 and the signal transmission module 403 are electrically connected by wires. The signal transmission module 403 is wirelessly connected to the external control module. Both the signal transmission module 403 and the gas molecule sensing module 404 are electrically connected to the power module 402 by wires.

[0022] like Figures 2-6 As shown, the outer wall of the insulating substrate 4 is provided with uniformly distributed adsorption holes 501, one end of the adsorption hole 501 is connected to the inside of the outer tire 2, and the other end of the adsorption hole 501 is connected to the inside of the gas molecule adsorption cavity 5.

[0023] like Figures 2-4 As shown, the assembly groove 201 is adapted to the device body 1. The outer wall of the device body 1 is provided with an adhesive layer 401, and the adhesive layer 401 is bonded to the inner wall of the assembly groove 201. The limiting flange 202 is provided along the side wall of the assembly groove 201 near the opening end, and the outer wall of the limiting flange 202 is in contact with the outer wall of the device body 1.

[0024] During installation, first align the main body 1 of the device with the mounting groove 201 on the inner wall of the outer tire 2. Then, firmly bond the adhesive layer 401 on the outer wall of the main body 1 to the inner wall of the mounting groove 201. Simultaneously, ensure that the limiting flange 202 on the side wall of the mounting groove 201 near the opening fits against the outer wall of the main body 1. This double-fixing method ensures that the main body 1 is stably installed at an equal angle between the outer tire 2 and the inner tire 3, preventing it from dislodging from its preset position due to vibration or displacement during vehicle operation. After assembly, the power module 402 supplies power to the gas molecule sensing module 404 and the signal transmission module 403 via wires, putting the device into monitoring mode. When the inner tire 3 experiences an initial minor leak, the leaked gas molecules will diffuse to... Between the outer tire 2 and the inner tube 3, some gas molecules directly enter the gas molecule adsorption chamber 5 through the adsorption pores 501 evenly distributed on the outer wall of the insulating substrate 4, while others diffuse to the surroundings under the influence of the concentration difference. The gas molecule sensing module 404 in the gas molecule adsorption chamber 5 captures the gas molecules entering the chamber in real time. When gas molecules are sensed, the gas molecule sensing module 404 transmits an electrical signal to the signal transmission module 403 through a wire. The signal transmission module 403 then sends a warning signal to an external control module, such as a display terminal in the vehicle's cockpit, through a wireless connection, so that the driver can detect the potential danger when the tire pressure has not dropped significantly.

[0025] Example 2: Please refer to Figures 1-6 Based on Embodiment 1, a guiding structure is also disclosed, the specific structure of which is as follows: The end of the main body 1 of the device is provided with a guiding structure for guiding leaked gas. The guiding structure includes a gas molecule guiding tube 6 fixedly installed at the end of the main body 1 of the device, and an air inlet 601 is opened on the outer wall of the gas molecule guiding tube 6. The two ends of the gas molecule guiding tube 6 are respectively connected to the ends of the two sets of the main body 1 of the device, and the gas molecule guiding tubes 6 are arranged at equal intervals. The gas molecule guiding tubes 6 are connected to the gas molecule adsorption chamber 5. The air inlets 601 are evenly distributed on the side wall of the gas molecule guiding tube 6, and the air inlets 601 on both sides of the gas molecule guiding tube 6 are staggered. The end of the air inlet 601 is connected to the inside of the outer tire 2.

[0026] The guiding structure is centered on the gas molecule guiding tube 6, with its two ends connected to the ends of two adjacent sets of device bodies 1. Its internal channels are connected to the gas molecule adsorption chamber 5 of the device body 1. Simultaneously, the gas molecule guiding tubes 6 are evenly spaced along the inner wall of the outer tire 2, forming a guiding and adsorption system covering the interior of the outer tire 2. When the inner tire 3 leaks air, the leaked gas molecules diffuse along the inner wall of the inner tire 3. The air inlets 601, evenly spaced and staggered on both sides of the outer wall of the gas molecule guiding tubes 6, can capture diffused gas molecules from different directions and positions, avoiding blind spots caused by single-direction air intake. Gas molecules entering the air inlets 601 are guided directionally by the internal channels of the guiding tubes, quickly flowing to the connected gas molecule adsorption chamber 5, shortening the path for gas molecules to reach the sensing module and improving gas capture efficiency. Through the linkage of multiple sets of guiding tubes with the device body 1, the dispersed leaking gas molecules are gathered into the adsorption chamber, enabling the gas molecule sensing module 404 to monitor more quickly, further enhancing the device's sensitivity to initial minor leaks and ensuring timely transmission of warning signals.
