[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to enable readers to better understand this utility model. However, the technical solutions claimed by this utility model can be implemented even without these technical details and with various changes and modifications based on the following embodiments.

[0019] To facilitate understanding of the embodiments of this application, relevant content regarding vehicle tire safety will be introduced first.

[0020] High tire temperatures are a particularly prominent issue for mining trucks operating under heavy loads for extended periods. In the high temperatures of summer, excessively high internal and external temperatures of the tires can easily lead to problems such as tire heat separation and bulges. Tire bulges are usually caused by poor adhesion or air bubbles between the rubber and fabric layers during manufacturing, which then cause them to be subjected to excessive pressure and high temperatures during operation. Heat separation can be caused by overloading, uneven loading, excessively high truck speeds, long-distance and long-duration operation leading to excessively high tire temperatures, or improper tire pressure. These problems not only shorten tire lifespan and increase transportation costs, but more importantly, they pose serious safety hazards to mining operations, potentially leading to serious accidents such as tire blowouts.

[0021] Example 1: The present invention relates to a tire condition management system.

[0022] Compared with the prior art, the present invention integrates a module built into the tire to comprehensively monitor the tire condition, which helps to detect tire abnormalities in a timely manner and prevent tire failures. In case of abnormal high temperature, the automatic spraying device can be driven to swing by controlling the swing mechanism, so that the automatic spraying device can accurately spray the tire to cool it down, effectively preventing performance degradation and potential safety risks caused by tire overheating, protecting tire performance and service life, and improving the safety and reliability of vehicle operation.

[0023] The following is a detailed description of the implementation details of the tire condition management system in this embodiment. The following content is only for the convenience of understanding and is not necessary for implementing this solution.

[0024] The present invention provides a tire condition management system, such as... Figure 1 As shown, it includes an integrated module 1, a controller 2, an automatic sprinkler device 3, and a swing mechanism 4; wherein: Integrated module 1 is built into the tire. Integrated module 1 includes a detection module for detecting tire status information, including tire acceleration, temperature and pressure. By detecting various data of the tire through the detection module, comprehensive monitoring can help to detect abnormal tire conditions in a timely manner and prevent tire failure. Controller 2 is connected to integration module 1 and is used to receive information fed back by integration module 1; The automatic spraying device 3 and the swing mechanism 4 are both connected to and controlled by the controller 2; the automatic spraying device 3 is used to cool the tire, and the automatic spraying device 3 is installed on the swing mechanism 4, which is used to drive the automatic spraying device 3 to swing upwards towards the tire. The controller 2 receives status information and sends control signals to the swing mechanism 4 and the automatic spraying device 3, thereby enabling automatic control of spraying and cooling based on status data, achieving precise spraying and cooling of the tires.

[0025] Specifically, such as Figure 2 and Figure 3 As shown, the detection module includes an acceleration sensor 11, a temperature sensor 12, a pressure sensor 13, and a control unit 14: the acceleration sensor 11 is used to collect tire acceleration; the temperature sensor 12 is used to collect tire temperature; the pressure sensor 13 is used to collect tire pressure; the control unit 14 is connected to the acceleration sensor 11, the temperature sensor 12, and the pressure sensor 13, and the control unit 14 is used to receive the status information and send it to the controller 2.

[0026] Furthermore, such as Figure 2 As shown, the integrated module 1 is connected to the controller 2 via a wireless communication device 5. The wireless communication device 5 includes a first wireless communication module 51 disposed within the integrated module 1 and a second wireless communication module 52 disposed on the controller 2. The first wireless communication module 51 is electrically connected to the control unit 14 and is wirelessly connected to the second wireless communication module 52. That is, in this embodiment, the control unit 14 establishes a wireless communication connection with the controller 2 through the first wireless communication module 51 and the second wireless communication module 52.

[0027] The communication method between the first and second wireless communication modules includes one or more of Bluetooth, WiFi, NB-IoT, and ZigBee.

[0028] Specifically, such as Figure 2 and Figure 6 As shown, the automatic spraying device 3 includes a nozzle 31 for spraying coolant onto the tires and a switching valve 32 connected to the nozzle 31; the opening and closing state of the switching valve 32 corresponds to the opening and closing state of the nozzle 31; the controller 2 is used to control the opening and closing of the switching valve 32, thereby controlling the opening and closing of the spray from the nozzle 31. By directly controlling the switching valve 32 through the controller 2, the opening and closing of the automatic spraying device 3 can be quickly controlled, improving the convenience of control operation.

[0029] Specifically, such as Figure 2 and Figure 6 As shown, the swing mechanism 4 is mounted on the chassis of the vehicle corresponding to the tire. The swing mechanism 4 includes a drive motor 41 and a linkage component 42 connected to the output end of the drive motor 41. The drive motor 41 is connected to and controlled by the controller 2 to drive the linkage component 42 to swing. The end of the linkage component 42 away from the drive motor 41 is connected to an automatic sprinkler device 3 to drive the automatic sprinkler device 3 to swing. The swing mechanism 4 can be controlled by directly controlling the start and stop of the drive motor 41 through the controller 2, improving the convenience of operation.

[0030] In some embodiments, the driving components of the swing mechanism 4 include a fixed base 421, a drive wheel 422, a linkage rod 423, and a linear slide 424. The drive wheel 422 is rotatably mounted on the fixed base 421 and connected to the output end of a drive motor 41, so that the drive motor 41 can drive it to rotate. One end of the linkage rod 423 is eccentrically hinged to the drive wheel 422, and the other end is hinged to the linear slide 424. A slide rail is installed on the fixed base 421 for the linear slide 424 to slide on, and the linear slide 424 is used for mounting the automatic spraying device 3. The drive motor 41 drives the drive wheel 422 to rotate, causing the linkage rod 423 to swing back and forth during rotation. This, in turn, causes the linear slide 424 to slide back and forth on the slide rail via the linkage rod 423, thereby driving the automatic spraying device 3 to slide back and forth, facilitating comprehensive spraying and cooling treatment of the tires.

[0031] In some embodiments, such as Figure 3 and Figure 5As shown, the tire condition management system provided in this embodiment also includes a speed sensor 6, which is installed on the wheel and used to detect the vehicle speed information corresponding to the tire. The controller 2 is connected to the speed sensor 6 to control the operation of the automatic spraying device 3 through the feedback information from the speed sensor 6. Specifically, the controller 2 has a speed change threshold set in it. By comparing the speed sensor 6 with the speed change threshold, it can detect whether the vehicle is braking suddenly. Then, when sudden braking occurs, it automatically controls the automatic spraying device 3 to spray and cool the tires, avoiding the impact of the high temperature caused by sudden braking on the tires.

[0032] In some embodiments, such as Figure 3 and Figure 5 As shown, the tire condition management system provided in this embodiment also includes a load sensor 7. The load sensor 7 is installed at the wheel cargo box where the wheel is applied. The load sensor 7 is connected to the controller 2 and is used to feed back the detected load information to the controller 2. Specifically, as shown... Figure 4 As shown, there are four load sensors 7, which are respectively located on the front, rear, left and right sides of the bottom of the vehicle cargo box, so that the load-bearing weight information of the vehicle cargo box can be comprehensively and accurately evaluated by simultaneously measuring the weight of the four load sensors 7.

[0033] In some embodiments, such as Figure 3 and Figure 5 As shown, the tire status management system provided in this embodiment also includes a remote control communication module 8 and a controller 2. One end of the remote control communication module 8 is connected to the controller 2, and the other end is connected to a remote controller 9. The remote controller 9 is used to generate control signals and send them to the controller 2 through the remote control communication module 8, so that the controller 2 can send control signals to the automatic spraying device 3 and the swing mechanism 4 for execution. The remote control communication module 8 allows the remote controller 9 to interact with the controller 2, thereby enabling remote control of the working status of the automatic spraying device 3 and the swing mechanism 4, enhancing the system's flexibility and response speed.

[0034] In some embodiments, such as Figure 3 and Figure 5 As shown, the tire status management system provided in this embodiment also includes a cloud communication module 10 and a cloud 101 connected to the cloud communication module 10; the cloud communication module 10 is connected to the controller 2 and is used to report the status information received by the controller 2 to the cloud 101. By reporting the collected data to the cloud 101 in real time through the cloud communication module 10, managers can view the tire status of each mining truck in the entire mining area on the cloud 101, which facilitates the monitoring of the tire status of each vehicle.

[0035] In some embodiments, such as Figure 3 and Figure 5As shown, the tire condition management system provided in this embodiment also includes an audible and visual alarm module 15. The audible and visual alarm module 15 is connected to the controller 2 so that when an abnormality is detected in the tire condition, the controller 2 can control the audible and visual alarm module 15 to issue an audible and visual alarm. Specifically, the audible and visual alarm module 15 includes a speaker and an LED light to provide both audible and flashing light alarms. The audible and visual alarm module 15 is installed in the driver's cab of the vehicle so that the driver can quickly receive alarm information and take timely action.

[0036] In some embodiments, such as Figure 3 and Figure 5 As shown, the tire status management system provided in this embodiment also includes a display screen 16, which is connected to the controller 2. The display screen 16 displays the health status of each tire and the working status of each automatic spraying device 3. The displayed information includes, but is not limited to, tire number, acceleration value of each tire, temperature value of each tire, pressure value of each tire, number of sprays for each tire, and working status of each automatic spraying device 3. In this embodiment, the display screen 16 is located in the driver's cab of the vehicle, allowing for quick monitoring of the status of each tire and the working information of the automatic spraying device 3 from the driver's cab.

[0037] The tire condition management system provided in this embodiment, by integrating the module 1 built into the tire, can comprehensively monitor the tire condition, which helps to detect tire abnormalities in a timely manner, prevent tire failures, and, in the event of abnormal high temperature, can control the drive motor 41 to start through the controller 2 and control the switch valve 32 to open, so that the drive motor 41 drives the drive wheel 422 to rotate, and then drives the linear slide block 424 to slide back and forth through the linkage rod 423, causing the nozzle 31 of the automatic spraying device 3 to swing back and forth towards the tire, thereby enabling the automatic spraying device 3 to precisely spray the tire to cool it down, and to cool the tire comprehensively, effectively preventing performance degradation and potential safety risks caused by tire overheating, protecting tire performance and service life, and improving the safety and reliability of vehicle operation.

[0038] Example 2 This utility model also provides an unmanned mining truck, see [link to relevant documentation]. Figure 5 and Figure 7 As shown, the unmanned mining truck includes wheels, tires mounted on the wheels, and the tire status management system described in Embodiment 1. In this embodiment, the tire status management system manages the tire information of the mining truck, facilitating the detection of tire condition and enabling timely and comprehensive cooling of the tires via spraying. This improves the comprehensiveness and effectiveness of cooling, protects tire performance and lifespan, and enhances the safety and reliability of vehicle operation.

[0039] Furthermore, the unmanned mining truck provided in this embodiment includes six wheels. Therefore, this system is configured with six tire-integrated modules 1, that is, each tire has a tire-integrated module 1 installed inside it. The tire-integrated module 1 is placed inside the tire, at the valve position, to facilitate independent monitoring of each tire.

[0040] Specifically, the unmanned mining truck mounts its wheels on a front and rear axle. The front axle has two wheels, and the rear axle has four. The two front wheels are located on the front sides of the truck, and the two rear wheels are located on the rear sides. Figure 3 As shown, two automatic spray devices 3 (not shown in the figure) are installed for each of the two wheels on the front axle. Because the two wheels on the rear axle are closer together, two automatic spray devices 3 (not shown in the figure) are installed for each of the two wheels on one side of the rear axle. The automatic spray devices 3 are directly installed on the chassis of the mining truck, so that the front axle wheels and the rear axle wheels can be sprayed and cooled independently according to the information of their respective tires.

[0041] Furthermore, the two wheels on the same side of the rear axle can be cooled simultaneously by an automatic spray device 3 in conjunction with the swing mechanism 4. That is, the swing mechanism 4 of the rear axle drives the automatic spray device 3 to move back and forth between the two wheels on the same side, so that the automatic spray device 3 in conjunction with the swing mechanism 4 can simultaneously cool the two wheels, rationally allocate resources, and reduce costs.

[0042] Correspondingly, the swing direction of the automatic spraying device 3 aligned on the front axle wheel can swing back and forth along the width direction of the wheel tire, so as to fully cover the tire surface during spraying, thereby promoting comprehensive spraying and cooling of the wheel tire during the wheel tire's movement, and improving the efficiency and accuracy of spraying and cooling.

In practical applications, the technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
