Description

Technical Field

[0001] The present invention relates to the technical field of vehicle tires, and in particular to a device and method for monitoring interference between a tire inner support body and the tire inner surface. Background Art

[0002] Tire blowouts and tire pressure loss during vehicle driving can cause serious safety accidents. Ordinary commercial vehicles will add tire protection emergency devices to ensure the stability of the tire after it is deflated. For off-road vehicles, especially military vehicles, the possibility of tire blowouts is greatly increased due to harsh road conditions, high loads, and high-speed driving. Simply ensuring the stability of the vehicle after deflation is no longer enough to meet usage requirements. In order to improve battlefield survivability, in most scenarios, the vehicle is required to be able to continue traveling for a certain distance in a deflated state to ensure the personal safety of the driver and passengers. At present, in order to achieve the above-mentioned performance and purposes, a tire internal support device is generally installed in the wheel to ensure that the vehicle can still be normally controlled and continue to travel safely for a certain distance in a deflated state.

[0003] In actual application, there should be no interference between the inner support and the inner surface of the tire, and there should be a sufficient safety distance between the outer surface of the inner support and the inner surface of the tire. However, during the driving process, due to factors such as road conditions, tire installation, insufficient tire pressure, deformation of the inner support, etc., the outer surface of the inner support and the inner surface of the tire may interfere with each other. If this interference collision is not discovered and handled in time, it may cause the tire side woven layer to delaminate, the inner surface of the tire to wear more severely, and the inner support to be damaged. bad It may even cause serious safety accidents such as tire blowout. However, there is currently a lack of an effective real-time monitoring device for the interference between the tire support body and the tire inner surface and an active alarm to solve this problem.

[0004] Chinese invention patent publication number CN113085449A discloses an intelligent and safe tire internal support device and control method. The technical problem to be solved by the invention patent is to be able to control the slip rate of the tire and the contact surface by controlling the wheel torque and tire temperature when the tire is suddenly under-pressure or zero-pressure, thereby improving the adhesion and stability of the tire. The invention patent does not solve the problem of real-time monitoring and alarm of interference between the tire internal support body and the inner surface of the tire. Summary of the Invention

[0005] The present invention aims to provide a device and method for monitoring the interference between the inner support body of a tire and the inner surface of the tire, so as to realize real-time monitoring and alarm of the interference between the inner support body of the tire and the inner surface of the tire.

[0006] To achieve the above objectives, the technical solution of the present invention is: A device for monitoring interference between an inner support body of a tire and the inner surface of the tire. The monitoring device includes multiple pressure sensors, which are evenly spaced and arranged on the outer surface of the inner support body of the tire. The multiple pressure sensors are located between the outer surface of the inner support body of the tire and the inner surface of the tire. The multiple pressure sensors are wirelessly connected to an on-board computer. When compression occurs between the inner support body and the inner surface of the tire, the pressure values collected by the pressure sensors are transmitted to the on-board computer.

[0007] Furthermore, the pressure sensor is a kinetic energy self-generating pressure sensor.

[0008] Furthermore, the kinetic energy self-generating pressure sensor includes a mounting base, which is fixed to the outer surface of the inner support body facing the inner surface of the tire by bolts.

After receiving the collected pressure value, the on-board computer displays the pressure value data on the on-board display screen; When the on-board computer receives the pressure data collected by the kinetic energy self-generating pressure sensor, the on-board computer issues an alarm.

[0010] Furthermore, the kinetic energy self-generating pressure sensor includes a micro-generator and a Wi-Fi wireless communication module. When compression occurs between the inner support body and the inner surface of the tire, the spherical probe of the kinetic energy self-generating pressure sensor converts the received pressure into displacement and drives the micro-generator to work. The micro-generator converts kinetic energy into electrical energy, which is stored in a micro-capacitor inside the kinetic energy self-generating pressure sensor. The Wi-Fi wireless communication module uses the electrical energy to send the collected pressure data to the on-board computer.

[0011] Furthermore, after the multiple kinetic energy self-generating pressure sensors are evenly spaced and arranged on the outer surface of the tire inner support body, the multiple kinetic energy self-generating pressure sensors are numbered in sequence. After each kinetic energy self-generating pressure sensor collects a pressure value, the pressure value is displayed on the vehicle display screen through the vehicle computer.

[0012] Furthermore, after the on-board computer receives the pressure value collected by the kinetic energy self-generating pressure sensor, the on-board computer activates the vehicle buzzer alarm to remind the user to check the pressure value data received on the on-board display screen.

[0023] In order to make the purpose, technical solutions and advantages of the invention clearer, the present invention is further described below with reference to the accompanying drawings.

[0024] like Figure 1As shown, the present invention discloses a device for monitoring interference between a tire inner support and the inner surface of the tire, comprising multiple pressure sensors 1. In one embodiment, the pressure sensors 1 may be kinetic energy self-generating pressure sensors, evenly spaced on the outer surface of the tire inner support 2, positioned between the outer surface of the tire inner support 2 and the inner surface of the tire 3. The multiple kinetic energy self-generating pressure sensors are wirelessly connected to an onboard computer. In practical applications, the multiple kinetic energy self-generating pressure sensors may be sequentially numbered.

[0025] like Figure 4 、 Figure 5 and Figure 6 As shown, the kinetic energy self-generating pressure sensor is mounted on the outside of the tire inner support 2. Regarding the installation of the kinetic energy self-generating pressure sensor on the inner support, the kinetic energy self-generating pressure sensor includes a mounting base, which can be mounted on the tire inner support 2 via a threaded connection. Structural adhesive is applied to the contact area between the mounting base and the tire inner support 2 for reinforcement.

[0026] The kinetic energy self-generating pressure sensor is located on the outer surfaces of both sides of the tire inner support body 2, and the kinetic energy self-generating pressure sensor is arranged toward the inner surface of the tire 3. In one embodiment, three kinetic energy self-generating pressure sensors are evenly spaced on the outer surface of each side of the tire inner support body 2 to facilitate dynamic balance adjustment of the tire. The kinetic energy self-generating pressure sensor is tilted at the side end of the tire inner support body 2, and the axis of the spherical probe of the kinetic energy self-generating pressure sensor is at an angle of 45° to the horizontal line, so that the kinetic energy self-generating pressure sensor can simultaneously receive pressure from the side, top and bottom surfaces of the tire 3.

[0027] As a preferred embodiment, in addition to installing kinetic energy self-generating pressure sensors on the outer surfaces of both sides of the tire inner support body 2, kinetic energy self-generating pressure sensors can also be installed on the top and bottom surfaces of the tire inner support body 2. When kinetic energy self-generating pressure sensors are installed on the top and bottom surfaces of the tire inner support body 2, the kinetic energy self-generating pressure sensors on the outer surfaces of both sides of the tire inner support body 2 can be installed horizontally.

[0028] The working principle of kinetic energy self-generating pressure sensor is mainly based on energy conversion and wireless communication technology. Figure 2 and Figure 3 As shown in the figure, the kinetic energy self-generating pressure sensor contains a micro generator and Wi-Fi wireless communication module. The magnet and coil inside the generator will move relative to each other, generating electromagnetic induction, thereby converting kinetic energy into electrical energy. The electrical energy is then stored in the micro capacitor inside the kinetic energy self-generating pressure sensor and used by the switch's Wi-Fi wireless communication module. Its working principle is as follows: When the kinetic energy self-generating pressure sensor is squeezed, a micro-generator converts kinetic energy into electrical energy, which is stored in a micro-capacitor inside the sensor. The Wi-Fi wireless communication module uses this energy to send wireless signals, establishing a wireless connection with the onboard computer and display, thereby providing fault alarms. The spherical probe of the kinetic energy self-generating pressure sensor converts pressure within a certain angle range into displacement, which drives the micro-generator.

[0029] When the inner support body 2 is squeezed against the inner surface of the tire 3, the kinetic energy self-generating pressure sensor generates electricity through the built-in micro-generator, and the electricity is stored in the capacitor to supply the Wi-Fi module with electricity. The Wi-Fi signal is converted into an alarm message through the on-board computer and displayed on the screen.

[0030] The present invention also discloses a method for monitoring interference between a tire inner support body 2 and an inner surface of a tire 3, the method comprising: Step 1: a plurality of kinetic energy self-generating pressure sensors are evenly spaced apart on the outer surface of the tire inner support body 2, and the plurality of kinetic energy self-generating pressure sensors are wirelessly connected to the vehicle-mounted computer.

[0031] Step 2: When the outer surface of the tire inner support body 2 is squeezed with the inner surface of the tire 3, the Wi-Fi wireless communication module of the kinetic energy self-generating pressure sensor transmits the pressure value collected by the sensor to the on-board computer. After receiving the collected pressure value, the on-board computer displays the pressure value data on the on-board display screen.

[0032] Step 3: When the on-board computer receives the pressure value collected by the kinetic energy self-generating pressure sensor, the on-board computer issues an alarm.

[0033] In actual engineering applications, the tire inner support 2 and the tire 3 are both installed on the rim 4. The tire inner support 2 cannot interfere with the inner surface of the tire, and there is a sufficient safety distance between the outer surface of the inner support and the inner surface of the tire. When the kinetic energy self-generating pressure sensor collects a pressure value, it indicates that the inner support has interfered with the inner surface of the tire. After the on-board computer receives the pressure value collected by the kinetic energy self-generating pressure sensor, the inner support needs to be inspected and repaired, and the inner support is restored or replaced according to the inspection result. In the present invention, when the on-board computer receives the pressure value collected by the kinetic energy self-generating pressure sensor, the on-board computer can activate the vehicle buzzer alarm to remind the driver to check the pressure value data received on the on-board display screen and repair or replace the inner support to prevent accidents.

[0034] The present invention also discloses a device comprising: at least one processor; and a memory communicatively connected to the at least one processor; wherein the memory stores instructions executable by the at least one processor, and the instructions are executed by the at least one processor to enable the at least one processor to execute the described method.

[0035] The present invention also discloses a computer-readable storage medium storing a computer program, which implements the method when executed by a processor.
