Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

A tire wear detection system 100 for a vehicle 1000 and the vehicle 1000 according to an embodiment of the present invention are described below with reference to fig. 1 to 6. The vehicle 1000 includes a vehicle body 200 and a tire 300, and the tire 300 is rotatable with respect to the vehicle body 200. The tire wear detection system 100 is used to detect the degree of wear of the tire 300.

As shown in fig. 1 to 2, in the tire wear detection system 100 for a vehicle 1000 according to the embodiment of the present invention, the vehicle body 200 includes a holder 210 provided above the tire 300, and since the tire 300 is rotatable with respect to the vehicle body 200, the tire 300 is rotatable with respect to the holder 210 included in the vehicle body 200, the tire 300 has a groove 310 on a circumferential wall surface thereof, and the tire wear detection system 100 includes the filling assembly 110 and the detection assembly 120.

Specifically, referring to fig. 2 to 3, the filling assembly 110 is embedded in the groove 310 and includes the rubber 111 and the light reflecting member 112, the rubber 111 is a transparent member, the outer surface S1 of the rubber 111 is coplanar with the outer circumferential surface of the tire 300, so as to illustrate that the outer surface S1 of the rubber 111 is not lower than or higher than the outer circumferential surface of the tire 300, and the light reflecting member 112 is disposed on the side of the rubber 111 close to the central axis of the tire 300, that is, the light reflecting member 112 is disposed on the inner surface S2 of the rubber 111.

Thus, referring to fig. 3, when light is irradiated to the outer surface S1 of the rubber member 111, the light may be reflected and refracted at the outer surface S1 of the rubber member 111, and the light refracted into the rubber member 111 may be reflected by the light reflecting member 112 on the inner surface S2 side of the rubber member 111 and may be refracted by the outer surface S1 of the rubber member 111 to be emitted out of the rubber member 111.

As shown in fig. 2-3, the detecting assembly 120 includes a transmitter 121 and a receiver 122, the transmitter 121 and the receiver 122 are disposed on the fixture 210 and spaced apart from each other along the circumferential direction of the tire 300, the tire 300 embedded with the filling assembly 110 is rotatable relative to the transmitter 121 and the receiver 122 disposed on the fixture 210, the transmitter 121 can transmit light to the tire 300, the tire 300 rotates relative to the fixture 210 to a certain time, the light transmitted from the transmitter 121 can be transmitted to the filling assembly 110 on the tire 300, wherein, of the light transmitted from the transmitter 121 to the rubber 111, a part of the light is reflected by the outer surface S1 of the rubber 111 to be received by the receiver 122 (such as the light M1 and M3 shown in fig. 3), and another part of the light is transmitted to the rubber 111, refracted by the outer surface S1 of the rubber 111 to the reflector 112, and reflected by the reflector 112 to the outer surface S1 of the rubber 111, And refracted by the outer surface S1 of the rubber member 111 to be received by the receiving device 122 (i.e., refracted light rays, which are refracted into the rubber member 111 by the outer surface S1 of the rubber member 111, reflected by the light reflecting member 112, and pass through the outer surface S1 of the rubber member 111, such as light rays M2, M4 shown in fig. 3).

For example, in the specific example shown in fig. 3, the outer surface S1 of the rubber 111 at the time of the previous inspection is defined as a pre-abrasion rubber surface a1, and the light reflected by the pre-abrasion rubber surface a1 is defined as: the light ray M1 reflected by the rubber member before wear, which is reflected by the light reflecting member 112 after being refracted by the rubber member surface a1 before wear and refracted through the rubber member surface a1 before wear, is defined as: the worn front reflector reflects ray M2. The outer surface S1' of the rubber 111 at the time of the latter inspection is defined as a worn rubber surface a2, and the light reflected by the worn rubber surface a2 is defined as: the light ray M3 reflected by the worn rubber member, which is refracted by the worn rubber member surface a2, reflected by the reflector 112, and refracted through the worn rubber member surface a2 is defined as: the reflector reflects light ray M4 after wear.

In the previous detection, the before-worn rubber piece reflected light M1 and the before-worn reflector reflected light M2 may be received by the receiving device 122, and thus, an area between the before-worn rubber piece reflected light M1 and the before-worn reflector reflected light M2 is an area where the receiving device 122 may detect reflected light (referred to as an before-worn light band). During the subsequent detection, the worn rubber member reflected light M3 and the worn reflector reflected light M4 may be received by the receiving device 122, and thus, an area between the worn rubber member reflected light M3 and the worn reflector reflected light M4 is an area where the receiving device 122 may detect reflected light (referred to as a worn light band). Thus, the receiver 122 can determine the degree of wear of the tire 300 from the detected deviation of the reflected light region, and can detect the degree of wear at any time and anywhere.

In short, as shown in fig. 3, the tire 300 has different wear degrees, and the incident position of the incident light is different, and the path along which the light passes is different due to the decrease in the tread height of the tire 300, so that the position of the light band formed by the reflected light and the refracted light is changed, and the current wear degree of the tire 300 can be determined from the change in the position, width, and the like of the light band.

In the field of vehicle technology, in order to detect the wear of tires, the related art indicates that a colored chimney type wear warning tire can be adopted, and colored rubber and tread components are compounded in a compounding extrusion mode in the process of processing the tread rubber of the tire. The colored glue is arranged at the minimum limit of safe driving of the tire of the passenger vehicle, so that the circumferential colored glue can be displayed when the tire reaches the safe abrasion degree after being abraded. However, the chimney type wear warning tire can only take effect once, and cannot detect the tire wear amount at any time and many times. In addition, there is a detection platform for detecting the wear condition of the tire in the related art, which can drive a vehicle into the detection platform and then detect the wear condition of the tire by using a detection device on the detection platform. However, this method cannot detect the vehicle at any time and any place, and the vehicle must be driven to the detection platform before detection.

In contrast, the tire wear detection system 100 for the vehicle 1000 according to the embodiment of the present invention can detect the wear of the tire 300 many times during the life cycle of the vehicle 1000, so as to detect the wear at any time. Moreover, the detection assembly 120 on the vehicle body 200 is matched with the filling assembly 110 embedded on the tire 300, so that the vehicle 1000 does not need to be driven to a detection platform for detection, and the detection can be carried out anywhere.

In addition, in order to avoid accidental errors from influencing the authenticity of results, the average value can be set and measured for multiple times in the program, the full life cycle of the whole vehicle is realized, the effectiveness of data can be corrected, the abrasion trend can be pre-judged, and the risk is reduced to the maximum extent. That is to say, the more the detection times, the larger the database can be, the more accurate the data can be made by removing the deviation data by using the database matching algorithm, and the more accurate the tire 300 wear degree can be predicted.

In addition, the physical properties of the rubber 111 and the tire 300 are similar or identical, so that the wear of the tire 300 is ensured to be similar or identical to the wear of the rubber 111, and the running noise of the vehicle 1000 can be reduced to a certain extent, and the riding comfort of the whole vehicle can be improved. For example, the rubber member 111 may be composed of a compounding agent, a filler and an accelerator. In the preparation of the rubber member 111, a compounding agent having a refractive index identical to that of the tire 300 may be selected, an amorphous magnesium carbonate may be selected as a filler, and a transparent oxidation accelerator may be selected as an accelerator. Or the filler can be transparent raw rubber ethylene propylene rubber EPR, natural rubber NR, butadiene rubber BR or styrene butadiene rubber SBR. Meanwhile, in order to improve the transparency of the rubber part 111, a transparent active agent thioacetamide or white carbon black can be added. Therefore, the transparency of the rubber piece 111 is improved as much as possible while the physical properties of the rubber piece 111 and the tire 300 are kept similar to the maximum extent (for example, the block stiffness of the rubber piece 111 and the tire 300 is similar, the rolling damping of the rubber piece 111 and the tire 300 is similar, the tread wear of the rubber piece 111 and the tire 300 is similar, and the like), so as to improve the accuracy of the wear detection system of the tire 300.

According to some embodiments of the present invention, in conjunction with fig. 5, tire 300 includes tread portion 320 and pattern groove portion 330, with grooves 310 formed in tread portion 320. Therefore, when the filling element 110 is embedded in the groove 310, the filling element 110 is not filled in the groove 330, so that the groove 310 can be opened according to the shape of the filling element 110, that is, the groove 310 can be processed into a shape matched with the filling element 110, so as to improve the embedding stability of the filling element 110 in the groove 310 and improve the working reliability of the filling element 110, for example, when the filling element 110 is embedded in the groove 310 formed on the tread 320, the problem that the peripheral wall surface of the tire 300 influences the transmission of light rays due to long-term wear to cause inaccuracy of an information vehicle owner can be avoided, and the judgment of the wear degree of the vehicle owner is prevented from being influenced.

However, the present invention is not limited thereto, and for example, in some other embodiments of the present invention, the filling member 110 may be filled in the groove portion 330, thereby simplifying processing and the like of the tire 300. Further, when the tire 300 includes the tread portion 320, the tread portion 320 is an outer peripheral surface of the tire 300, that is, the outer surface S1 of the rubber 111 is coplanar with the tread portion 320.

In some embodiments of the present invention, as shown in fig. 4-5, the filling assembly 110 may be plural, and at least two filling assemblies 110 are spaced apart in the axial direction of the tire 300 (as shown in the direction F1 in fig. 4). Therefore, at least two sets of light beams can be reflected by the at least two filling assemblies 110 to the receiving device 122, so that the receiving device 122 can determine the wear degree of the tire 300 according to at least two sets of data, and the accuracy of the receiving device 122 in determining the wear degree of the tire 300 can be improved, thereby increasing the accuracy of the detection of the tire wear detection system 100. Moreover, by disposing at least two filling members 110 at intervals in the axial direction of the tire 300, it is possible to determine whether the tire 300 has the partial wear phenomenon, that is, whether there is a problem that one filling member 110 is worn more seriously than the other filling member 110, according to the extent of the region where the light is reflected after the two filling members 110 are worn.

According to some embodiments of the present invention, the filling assembly 110 may be plural, and at least two filling assemblies 110 are disposed at intervals in the circumferential direction of the tire 300 (the direction of F2 as shown in fig. 4). Therefore, at least two sets of light beams can be reflected by the at least two filling assemblies 110 to the receiving device 122, so that the receiving device 122 can determine the wear degree of the tire 300 according to at least two sets of data, and the accuracy of the receiving device 122 in determining the wear degree of the tire 300 can be improved, thereby increasing the accuracy of the detection of the tire wear detection system 100. Further, by disposing at least two filling assemblies 110 so as to be spaced apart in the circumferential direction of the tire 300, it is possible to make a plurality of filling assemblies 110 have more disposition spaces, and it is possible to arrange a larger number of filling assemblies 110.

In some embodiments of the present invention, as shown in fig. 4-5, the detection assembly 120 is located in a central region X of the tire 300 in the axial direction. The central region X is not meant to be a position at the center in the axial direction, but is to be understood in a broad sense as long as it is near the position at the center in the axial direction, and for example, the tire 300 is equally divided into N equal parts (N may be 3, 4, 5, 6, etc.) in the axial direction, and the middle part may be the central region X. Since the outer surface of the central region X of the tire 300 is slightly higher than the two side edge regions in the axial direction of the tire 300, the filling assembly 110 is located in the central region X, so that the wear amount of the filling assembly 110 is closer to that of the tire 300, and the wear degree of the tire 300 can be predicted more accurately.

In some embodiments of the present invention, as shown in FIG. 1, tire wear detection system 100 further includes a switching device 130, switching device 130 being electrically connected to detection assembly 120. The switch device 130 may facilitate the driver and the passenger to start the detecting component 120, so that the emitting device 121 may emit light, and the receiving device 122 may receive light, thereby determining the degree of wear of the tire 300. For example, after the tire wear detecting system 100 is started, the emitting device 121 may emit light, and during the rotation of the tire 300, when the rubber member 111 rotates to a position where the light can be irradiated, part of the light is reflected by the outer surface S1 of the rubber member 111 and received by the receiving device 122, and part of the light enters the rubber member 111, is refracted, is reflected by the reflective member 112, is refracted by the outer surface S1 of the rubber member 111 and received by the receiving device 122, so that the receiving device 122 may detect the reflective light region, and the wear degree of the tire 300 may be determined according to the detected change of the reflective light region.

For example, in some specific examples, the switching device 130 is provided within the vehicle body 200 to be adapted to be activated by an occupant. The driver or passenger can start the tire wear detection system 100 to detect the wear condition of the tire 300 at any time in the vehicle body 200 (not limited to the driving state or the parking state). Of course, the present invention is not limited to this, and in another embodiment of the present invention, the switch device 130 may be provided on a remote controller or the like, and the remote controller is not limited to use in the vehicle body 200.

According to some embodiments of the present invention, as shown in fig. 1, the tire wear detection system 100 further includes an alarm device 140, and the alarm device 140 is electrically connected to the detection assembly 120, so that an alarm, such as a prompt to the driver or passenger that the tire 300 needs to be replaced, can be issued at a proper time according to the detected degree of wear of the tire 300. For example, when the receiving device 122 determines that the tire 300 is worn to the extent that the tire needs to be replaced according to the area receiving the light, the alarm device 140 may be activated, and the alarm device 140 may intuitively remind the driver and the passenger that the tire 300 needs to be replaced through voice, flash, text, and the like, so as to reduce the probability that the vehicle 1000 is dangerous due to the loss of the tire 300, thereby improving the safety of the vehicle 1000. In addition, the alarm device 140 may be a flashing alarm light or an audible alarm for the convenience of prompting the driver and the passenger for identification, and is not limited specifically here. Further, the specific installation position of the alarm device 140 is not limited, and may be, for example, in the vehicle body 200 or the like.

In the related art, the chimney type abrasion warning tire is not suitable for the driver to use, but is not suitable for the driver to use, and the driver still has a risk. In the tire wear detection system 100 according to the embodiment of the present invention, the alarm device 140 is provided to prompt the driver or the passenger whether the tire 300 needs to be replaced, so that the probability of the driver or the passenger neglecting the tire is low, the probability of the vehicle 1000 causing danger due to the loss of the tire 300 can be reduced, and the safety of the vehicle 1000 can be improved.

In some embodiments of the present invention, as shown in fig. 1-2, the fixing member 210 may be a wheel cover provided on the vehicle body 200 itself, thereby facilitating the rotation of the tire 300 during the running of the vehicle 1000 and avoiding interference with the fixing member 210 when the tire 300 rotates. Moreover, the wheel cover of the vehicle body 200 itself is used as the fixing member 210, so that the installation of the detection assembly 120 can be simplified, and other installation seats are not required to be additionally arranged, thereby reducing the cost. Moreover, since there is no obstacle between the wheel cover and the tire 300, the interference of other components during the light emitting and receiving processes can be avoided, so that the effectiveness and reliability of the detection work performed by the detection assembly 120 can be ensured.

For example, in some embodiments of the present invention, after the occupant activates the switch device 130, the emitting device 121 may continuously emit light at a specific frequency, in a low-speed driving state of the vehicle 1000, every time the tire 300 rotates until the rubber 111 passes through the light, a part of the light is reflected by the rubber 111, received by the receiving device 122, refracted by the rubber 111, reflected by the reflective member 112, refracted by the outer surface S1 of the rubber 111, received by the receiving device 122, processed by the processing unit, fed back into the vehicle, and directly read by the occupant in the form of the tread pattern depth of the tire 300, so that the occupant can grasp the wear amount and the wear trend map of the tire 300 in the current state. It should be noted that the processing unit may be configured to process information such as the position and the width of the acquired optical tape, and the algorithm is simple and can be completed by a central processing unit of the vehicle 1000, so the processing unit may be a processing unit of the detection assembly 120 itself or a central processing unit.

Further, if the processing unit has a strong calculation capability, it is also possible to visually display the wear trend line of the tire 300 and to predict the remaining mileage that the tire 300 can travel, the remaining number of days of use, and the like. For example, a tire wear graph as shown in fig. 6 may be processed, in which the abscissa represents the mileage (unit kilometer) of the tire 300, the left ordinate represents the tread depth (unit millimeter), and the right ordinate represents the number of days (unit day) of use of the tire 300, wherein the tread depth curve may be the actual value of the tread depth measured by the detecting component 120, the tire wear curve may be a tire wear trend line fitted according to the tread depth curve, the driver may predict the mileage of the tire 300 when the tire 300 is worn to a critical value to be replaced according to the tire wear curve, and the remaining mileage that the tire 300 can travel is known by subtracting the current mileage from the mileage of the tire 300 when the tire 300 is worn to the critical value to be replaced.

The usage days curve may be an actual value of the usage days of the tire 300, the usage days trend line may be a trend line of the usage days of the tire 300 fitted according to the usage days curve, the trend line of the usage days shown in fig. 6 coincides with the usage days curve, and according to the usage days trend line and the tire wear curve, a driver and a passenger may predict how many days the tire 300 can be used when worn to a critical value to be replaced, and the remaining usage days of the tire 300 may be known by subtracting the number of days currently driven from the number of days in common.

For example, it can be known from the tread depth curve that when the tread depth is 1.5 mm, it indicates that the tire 300 should be replaced, at this time, the driving range (e.g., 6 km) corresponding to 1.5 mm can be found from the tire wear curve, and when the tire 300 is worn to a critical value to be replaced, the driving range is 6 km, which is the driving range of the tire 300, for example, the current tread depth is 3 mm, the driving range corresponding to 3 mm of the current tread depth is 3.5 km, and the remaining driving range of the tire 300 can be obtained by subtracting 3.5 km from 6 km. Then, by using the trend line of days of use, it can be known that the number of days of travel corresponding to a tire pattern depth of 1.5 mm is 720 days, and 720 days is the total number of days that the tire 300 can be used when the tire 300 is worn to a critical value that needs to be replaced, for example, the current tire pattern depth is 3 mm, and the current number of days of use of the tire 300 can be known from the curve of the number of days of use, for example, 410 days, and the number of days of use left for the tire 300 is obtained by subtracting 410 days from 720 days.

In summary, according to the tire wear detection system 100 of some embodiments of the present invention, the wear information of the current tire 300 can be detected in real time, which is not limited by time and space, and is not a disposable reminding device, but can continuously provide information, so that the driver and the passenger can know the wear condition of the current tire 300 of the vehicle 1000 in real time, and thus determine whether to replace the tire 300. Moreover, the detected data may be recorded in a database of the vehicle 1000 to modify the tire wear profile so that the anticipation of partial wear and tire 300 wear may be more accurate.

The vehicle 1000 according to an embodiment of the present invention includes the tire wear detection system 100 for the vehicle 1000 as described above. This makes it possible to detect the wear of the tire 300 at any time and anywhere.

In some embodiments of the present invention, as shown in fig. 1, the vehicle 1000 further includes a sound-collecting device 400, and the sound-collecting device 400 is used for collecting friction noise generated between the tire 300 and the ground during the running of the vehicle 1000. Specifically, the sound pickup device 400 may be mounted on the vehicle body 200 close to the tire 300, so that the sound pickup device 400 collects friction noise generated between the tire 300 and the ground, and the sound pickup device 400 may be connected to a central processing unit or the like of the vehicle 1000, and the central processing unit may determine whether the road surface condition is dry or wet according to the frequency of the friction noise. For example, the frequency band of the friction noise corresponding to a dry road surface and the frequency band of the friction noise corresponding to a wet road surface may be implanted into the central processing unit, and the road surface condition may be known to be dry or wet by analyzing the frequency of the friction noise collected by the radio.
