[0040] Embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0041] When the rim bolts of a car are not tightened, they will gradually loosen during driving, eventually causing the rim to detach from the car, which usually causes the car to lose control or even roll over. Most existing monitoring methods rely on regular manual inspections of bolt tightness, which is cumbersome and cannot achieve real-time monitoring, posing a major safety hazard.

[0042] In view of the above situation, the present disclosure provides a looseness-detectable automobile wheel. Figure 1 FIG. 1 is a schematic diagram of a loose and detectable automobile wheel structure according to an exemplary embodiment. Figure 1 As shown, the looseness detectable automobile wheel comprises:

[0043] Rim 01;

[0044] Wheel decorative cover 02, fixed at the center of the wheel rim;

[0045] A signal transmitting device, comprising a positive electrode, a negative electrode, a battery connected between the positive electrode and the negative electrode, and a signal generator; wherein the positive electrode and the negative electrode are fixed side by side on the outside of the wheel decorative cover 02;

[0046] When the wheel decorative cover 02 is fixed at the center of the rim 01, the positive electrode and the negative electrode on the outside of the wheel decorative cover are conductively connected through the bearing 03 of the rim, so that the circuits among the battery, the positive electrode, the negative electrode and the signal generator are connected; wherein the electrodes of the positive electrode and the negative electrode that are away from the bearing are located at the edge of the bearing.

[0047] In this exemplary embodiment, the signal transmitter can be installed in the wheel of the automobile, and the positive electrode and the negative electrode are fixed side by side on the outside of the wheel decorative cover. When the wheel decorative cover is fixed at the center of the rim, the positive electrode and the negative electrode on the outside of the wheel decorative cover are both connected to the bearing of the rim; at the same time, the electrode of the positive electrode and the negative electrode away from the bearing is located at the edge of the bearing, so that the positive electrode and the negative electrode are conductively connected through the bearing of the rim, so that the signal generator transmits a signal to the outside, and when the rim begins to move outward and fall off, the rim can drive the positive electrode and the negative electrode to move outward and fall off the contact with the bearing, so that the signal generator stops transmitting a signal to the outside, and then it can be determined whether the rim begins to fall off according to the signal transmission state of the signal generator, so as to improve the driving safety of the automobile. Among them, the positive electrode and the negative electrode are one of 04 and 06, that is, the positive electrode can be electrode 04 or electrode 06; the negative electrode can also be electrode 04 or electrode 06. Among them, the electrode of the positive electrode and the negative electrode that is far away from the bearing is located at the edge of the bearing. It can be determined that the distance between the positive electrode and the negative electrode that is far away from the bearing and the edge of the bearing (the edge of the bearing here is the edge close to the electrode) can range from 3 to 4 mm.

[0048] In this exemplary embodiment, the battery and the signal generator are fixed on the inner side of the wheel decorative cover. By fixing the battery and the signal generator on the inner side of the wheel decorative cover, when the wheel rotates, the battery and the signal generator are driven to rotate with the wheel, thereby avoiding the situation where the battery and the signal generator interfere with the normal rotation of the wheel.

[0049] In this exemplary embodiment, the bearing may be a brake bearing. When the wheel trim cover is fixed at the center of the wheel rim, the wheel trim cover is just coaxially mounted at the center of the wheel rim.

[0050] In some embodiments, Figure 2 A schematic diagram of a wheel decorative cover structure according to an exemplary embodiment is shown. Figure 1 .like Figure 2 As shown, the wheel decorative cover includes a flat top and a support portion 05 extending from the surface of the flat top;

[0051] When the wheel decorative cover is fixed at the center of the rim, the support portion 05 extends into the center of the rim and contacts the bearing of the rim; wherein the positive electrode and the negative electrode are both spring-shaped structure electrodes;

[0052] The positive electrode of the snap-spring-shaped structure and the negative electrode of the snap-spring-shaped structure are fixed to the outside of the support portion 05 of the wheel decorative cover.

[0053] In this exemplary embodiment, Figure 2 As shown, the positive electrode 04 and the negative electrode can both be spring-shaped structure electrodes, fixed on the outside of the support portion 05 of the wheel decorative cover. The support portion 05 of the wheel decorative cover contacts the bearing, so that the positive electrode and the negative electrode can both contact the bearing, thereby achieving electrical conduction between the positive electrode and the negative electrode, so that the signal generator forms a conductive path and can emit signals externally.

[0054] In some embodiments, the positive electrode and the negative electrode are both ring-shaped structures.

[0055] In the present exemplary embodiment, the positive electrode and the negative electrode having a circular ring structure can be more easily fixed to the outside of the support portion of the wheel trim cover.

[0056] In some embodiments, the bearing of the rim is made of conductive material.

[0057] In this exemplary embodiment, the positive electrode and the negative electrode are both annular structures, so that the positive electrode and the negative electrode are both fixed on the outside of the support portion of the wheel decorative cover. The bearing of the rim is a conductive material, so that the positive electrode and the negative electrode are conductively connected, so that the signal generator forms a conductive path and can emit signals externally. Among them, the conductive material can be a conductive iron material. Figure 3 A schematic diagram of a wheel decorative cover structure according to an exemplary embodiment is shown. Figure 2 .like Figure 3 As shown, the signal generator 07 can be located in the flat top portion 08 of the wheel decorative cover. At the same time, when the rim starts to fall off and move outward, the positive electrode and the negative electrode move outward with the rim, and the electrode of the positive electrode and the negative electrode far from the bearing can fall off and connect with the bearing, so that the signal generator stops emitting signals to the outside, and then it can be determined whether the rim starts to fall off according to the signal emission state of the signal generator, so as to improve the driving safety of the car.

[0058] In this exemplary embodiment, in order to improve the detection accuracy, a vibration detection sensor can be added to the wheel rim. The vibration detection sensor is used to detect the vibration frequency of the wheel when the vehicle is running. The wheel abnormality is detected by the vibration frequency of the vehicle. When it is found that the signal generator of the signal transmitting device stops transmitting the signal, the vibration frequency of the vehicle wheel detected by the vibration detection sensor can be analyzed, so as to facilitate the detection of whether the vehicle wheel is loose.

[0059] The present disclosure provides a vehicle capable of detecting loose wheels, comprising the loose detectable vehicle wheel described in the first aspect above, and a signal detection device; wherein:

[0060] The signal detection device is used to detect the signal emitted by the signal generator, and when it is determined that the signal generator does not emit a signal, it is determined that the wheel is loose; wherein,

[0061] When the wheel rim is loose, the electrode of the positive electrode and the negative electrode that is away from the bearing is separated from the bearing, so that the signal generator stops emitting signals.

[0062] In this exemplary embodiment, the loose state of the wheel in the vehicle can be detected, a signal transmitter is installed in the wheel, and a signal detection device is installed in the vehicle. The positive electrode and the negative electrode of the signal transmitter are fixed side by side on the outside of the wheel decorative cover. When the wheel decorative cover is fixed at the center of the rim, the positive electrode and the negative electrode on the outside of the wheel decorative cover are both connected to the bearing of the rim; at the same time, the electrodes of the positive electrode and the negative electrode away from the bearing are located at the edge of the bearing, so that the positive electrode and the negative electrode are conductively connected through the bearing of the rim, so that the signal generator transmits a signal to the outside, and when the rim begins to move outward and fall off, the rim can drive the positive electrode and the negative electrode to move outward and fall off the contact with the bearing, so that the signal generator stops transmitting the signal to the outside, and then it can be determined whether the rim begins to fall off according to the signal transmission state of the signal generator, so as to improve the safety of the driving state of the vehicle.

[0063] The present disclosure provides a method for identifying looseness of a car rim, which is applied to a car wheel provided with a signal transmitter, wherein the signal transmitter comprises a positive electrode, a negative electrode, a battery connected between the positive electrode and the negative electrode, and a signal generator, wherein the positive electrode and the negative electrode are fixed side by side on the outside of a wheel decorative cover; the battery and the signal generator are fixed on the inside of the wheel decorative cover, and the electrode of the positive electrode and the negative electrode that is away from the bearing is located at the edge of the bearing; the wheel decorative cover is fixed at the center of the rim;

[0064] The method comprises:

[0065] Step 10, based on the conductive connection between the positive electrode and the negative electrode through the bearing of the rim, triggering the signal generator to emit a signal externally;

When the wheel decorative cover is fixed at the center of the rim, the positive electrode and the negative electrode on the outside of the wheel decorative cover are both connected to the bearing of the rim; at the same time, the electrodes of the positive electrode and the negative electrode away from the bearing are located at the edge of the bearing, so that the positive electrode and the negative electrode are conductively connected through the bearing of the rim, so that the signal generator transmits a signal to the outside, and when the rim begins to move outward and fall off, the rim can drive the positive electrode and the negative electrode to move outward and fall off the contact with the bearing, so that the signal generator stops transmitting the signal to the outside, and then it can be determined whether the rim begins to fall off according to the signal transmission state of the signal generator, so as to improve the safety of the driving state of the vehicle.

[0071] If the signal detection device detects the signal emitted by the signal generator, it is determined that the rim state of the vehicle wheel is a normal rim state.

[0072] In this exemplary embodiment, the rim state of the vehicle wheel can be determined based on the signal transmission state of the signal generator emitting a signal detected by the signal detection device. For example, if the signal detection device cannot detect the signal emitted by the signal generator, the rim state of the vehicle wheel is determined to be a rim-off state; if the signal detection device detects the signal emitted by the signal generator, the rim state of the vehicle wheel is determined to be a rim-normal state, which can improve the driving safety of the vehicle.

[0073] In some embodiments, including:

[0074] If the signal detection device cannot detect the signal emitted by the signal generator, the fault warning information of the automobile wheel rim fault is broadcasted through the vehicle control system.

[0075] In this exemplary embodiment, for the sake of vehicle driving safety, when the signal detection device cannot detect the signal emitted by the signal generator, the vehicle may have a rim detachment fault, and at this time, the vehicle control system may broadcast a fault warning message of the vehicle rim fault. The vehicle control system broadcasts the fault warning message of the vehicle rim fault to remind the driver that the vehicle has a rim detachment fault, so as to draw the driver's attention to safety.

[0076] In some embodiments, including:

[0077] If the signal detection device cannot detect the signal emitted by the signal generator, the vehicle control system controls the safety warning light to turn on.

[0078] In this exemplary embodiment, for the safety of vehicle driving, when the signal detection device cannot detect the signal emitted by the signal generator, the vehicle may have a rim detachment failure.
