If it is not replaced or repaired in time, it may cause serious consequences such as tire blowout and loss of grip, increasing the risk of traffic accidents. At present, there are two main methods for tire wear monitoring technology: visual diagnosis and physical diagnosis. Visual diagnosis: This method uses a camera to capture an image of the tire surface and estimates the wear of the tire by calculating the area of ​​the black area in the image. However, this method is affected by grayscale errors and light, and cannot accurately judge the wear of the tire. Physical diagnosis: Physical diagnosis technology monitors the degree of tire wear by installing sensors. These sensors can measure the wear of the tire through ultrasound, microwaves or magnetic fields. However, this method requires sophisticated equipment and high costs, and is not suitable for large-scale application. Therefore, it is very necessary to monitor tire wear and give warnings.

[0003] In the prior art, during the safe use of a vehicle, the tire wear warning device cannot quickly judge and analyze the wear or foreign matter blockage of the tire and give a corresponding signal; therefore, we make improvements on this and propose a tire wear warning device.

[0027] like Figure 1-5 As shown, the present embodiment proposes a tire wear warning device, comprising a tire body 1, a central embedding groove 2 is provided in the center of the tire body 1, a plurality of linkage circular grooves 4 are embedded in the inner end of the central embedding groove 2, a plate groove 5 is provided at the inner end of the linkage circular groove 4, an embedding ring 3 is provided between the plate grooves 5, a linkage spring 7 and a movable plate 6 are provided at the inner end of the plate groove 5, a warning device 8 is provided at the upper end of the movable plate 6, an upper connecting rod 9 is provided at the tail end of the warning device 8, an auxiliary threaded plate 12 is provided at the inner end of the upper connecting rod 9, a threaded rod 10 is provided at the inner end of the auxiliary threaded plate 12, a linkage fan 11 is provided at the head end of the threaded rod 10, and the outer end of the warning device 8 is wrapped with a protective leather cover 13.

[0028] The linkage circular grooves 4 are arranged at equal intervals along the central embedding groove 2, the plate grooves 5 are embedded in the linkage circular grooves 4, and the plate grooves 5 are fixedly connected by embedding rings 3, and the embedding rings 3 are made of elastic material.

[0029] During the installation process, the warning device connected to the embedding ring 3 is inserted as a whole into the central embedding groove 2 so that the warning device is stably connected.

[0030] The embedding ring 3 is embedded and installed in the central embedding groove 2 , one end of the linkage spring 7 is fixedly connected to the plate groove 5 , and the other end of the linkage spring 7 is fixedly connected to the movable plate 6 , and the movable plate 6 slides up and down along the plate groove 5 .

[0031] The movable plate 6 and the warning device 8 are connected to each other, which can ensure that after the tire is worn, the warning device 8 bounces inwards to avoid the warning device 8 being crushed.

[0032] The upper end of the movable plate 6 is fixedly connected to the alarm device 8 , the open end of the plate slot 5 is fixedly connected to the upper connecting rod 9 , and the inner end of the movable plate 6 is fixedly connected to the auxiliary threaded plate 12 .

[0033] By means of the movable plate 6, it is possible to facilitate the movement of the auxiliary threaded plate 12 to follow the movement of the warning device 8 being pressed inwards;

[0034] The movable plate 6 is located at the inner end of the upper connecting rod 9 , and the upper connecting rod 9 can limit the movement range of the movable plate 6 .

[0035] The center of the auxiliary threaded plate 12 is threadedly connected to the threaded rod 10 , and both ends of the threaded rod 10 are movable in the upper connecting rod 9 and the plate groove 5 respectively.

[0036] The auxiliary threaded plate 12 moves in the plate groove 5, driving the threaded rod 10 to rotate in the upper connecting rod 9 and the plate groove 5.

[0037] The linked fan 11 is fixedly mounted on the head end of the threaded rod 10 , and the outer end of the alarm 8 is covered by a protective leather cover 13 , and the outer edge of the protective leather cover 13 is fixed in the central embedding groove 2 .

[0038] Through the protective leather cover 13, when foreign objects such as stones are stuck in the tire, the wear warning of the alarm device 8 will not be triggered. After the tire is worn to the point that the protective leather cover 13 is damaged, the wear warning of the alarm device 8 will be triggered.

[0039] First, install the plate groove 5 connected to the embedding ring 3 in the central embedding groove 2, and then wrap the protective leather cover 13 on the outer end of the central embedding groove 2. The protective leather cover 13 is used to protect the warning device 8. When the tire is installed on the car and driving, there will be foreign objects such as gravel on the road surface of the car, which are easy to get stuck in the central embedding groove 2. After the foreign object is stuck in the central embedding groove 2, it will squeeze the warning device 8 connected to the protective leather cover 13. At this time, the warning device 8 will move backward along the plate groove 5 through the movable plate 6 to squeeze the linkage spring 7. During the squeezing process, the movable plate 6 is The connected embedded threaded plate slides along the corresponding threaded rod 10, pushing the threaded rod 10 to rotate, driving the linkage fan 11 located at the outer end of the threaded rod 10 to rotate, and during the rotation of the linkage fan 11, the part is subjected to heat dissipation and cooling treatment. At this time, the protective leather cover 13 corresponding to the outer end of the linkage fan 11 is blocked to block the wind of the linkage fan 11. The warning device 8 at the corresponding part can detect that the corresponding part is not worn by the tire, but squeezed by foreign objects through the induction of the resistance wind. Then, the foreign object signal is transmitted to the vehicle central control through the warning device 8 to notify the owner to deal with the foreign object;

[0040] If the protective leather cover 13 is damaged by vehicle wear, gaps or holes will appear in the protective leather cover 13. During this process, the return amount of wind at the same rotation speed of the linked fan 11 is inconsistent. The alarm 8 determines that the wear of this part exceeds the standard value, and then returns the information that the tire is too worn and needs to be replaced to the central control screen.

[0041] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the present invention are included in the scope of the claims of the present invention.
