[0026] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0027] On the one hand, the present invention provides a device for detecting tread wear of automobile tires, including a detection unit 100, wherein the detection unit 100 includes a base 1, a motion module 3 and a tread depth detector 4. A groove 2 is provided on the base 1, and the opening of the groove 2 serves as a detection area for the tread wear of the tire; the motion module 3 is arranged in the groove 2, and the tread depth detector 4 is installed on the motion module 3 and can move along the length and width directions of the groove 2 with the motion module 3 to detect the tread depth of the tire at the opening of the groove 2.

[0028] A groove 2 serving as a detection area for tire tread wear is provided on the base 1 of the detection unit 100, a motion module 3 is arranged in the groove 2, and a tread depth detector 4 is installed on the motion module 3 and can move along the length and width directions of the groove 2 with the motion module 3 to detect the tread depth of the tire located at the opening of the groove 2; the car is driven above the detection device, the tire is parked on the base 1 and corresponds to the detection area, and the tire tread can be detected without disassembling the car tire, which is convenient and quick, effectively improves the detection efficiency, and saves the detection cost.

[0029] As an optional implementation, the motion module 3 includes a cross-shaped first direction motion component and a second direction motion component, the pattern depth detector 4 can be slidably installed on the second direction motion component, and the second direction motion component can be slidably set on the first direction motion component.

[0030] The use of a cross-shaped first-direction motion component and a cross-shaped second-direction motion component as a driving component for the pattern depth detector 4 to move in two vertical directions facilitates control and positioning.

[0031] As an optional embodiment, the first direction movement component includes a first motor and a first slide rail 31 arranged along the length direction of the groove 2, and the second direction movement component includes a second motor and a second slide rail 32 arranged along the width direction of the groove 2. The second slide rail 32 can be slidably installed on the first slide rail 31 and is connected to the first driving member; the pattern depth detector 4 can be slidably installed on the second slide rail 32 and is connected to the second motor.

[0032] It adopts the method of sliding along the slide rail, with small movement resistance, smooth movement and good guidance.

[0033] As an optional implementation, the pattern depth detector 4 is a distance sensor.

[0034] The distance sensor is used to measure the tire tread depth, which is accurate and low in cost.

[0035] As an optional implementation, the number of the detection units 100 is two, and the two bases 1 are arranged side by side and connected via a connecting portion 5 .

[0036] Reference Figure 2 The two openings on the left and right above the square base 1 are for the convenience of parking the truck in the detection area without lifting the truck for detection. Because the tire spacing of different trucks is different, the detection range of the square base 1 cannot be too small. The groove 2 is about 1 meter long and can adapt to tires of different models and sizes (the width of a single tire of a truck is about 300mm and the width of a double tire is about 700mm. The reserved 300mm is to adapt to different models). Because the width of the car is different, the wheelbase is also very different, and there are one tire on one side and two tires on one side, so the detection range of 1 meter on the left and right is to be able to detect a variety of models; in addition, in order to detect the vehicle more conveniently and quickly, the square base 1 can simultaneously detect the two front wheels or four rear wheels on the same axis, so the purpose of rapid detection can be achieved.

[0037] As an optional implementation, Figure 3 As shown, the detection unit 100 also includes a general control unit, a controller and a display. The general control unit includes an information collection module, an information analysis module and an information feedback module; the information collection module is signal-connected to the pattern depth detector 4, and the general control unit is signal-connected to the controller; the controller is signal-connected to the motion module 3, and the information feedback module is signal-connected to the display.

[0038] like Figure 1 and Figure 2 A truck tire tread wear detection device provided as a specific embodiment of the present invention includes a square base 1, a controller and a display. Open areas are provided on both sides of the top of the square base 1, and the opening area is a detection area. A tire is supported by the square base 1; the detection area includes a cross-shaped linear motion module 3, and the cross-shaped linear motion module 3 includes a first direction motion component and a second direction motion component. A distance sensor serving as a tire tread depth detector 4 is provided on the second direction motion component.

[0039] The tire tread depth detector 4 is fixedly connected to the second direction motion component, and is driven to move longitudinally by the second direction motion component. The second direction motion component is fixedly connected to the first direction motion component, and is driven to move transversely by the first direction motion component. The two motion components are combined to drive the distance sensor to realize movement in the X and Y directions;

[0040] The tire tread depth detector 4 is connected to a general control unit, which includes an information collection module, an information analysis module and an information feedback module. The general control unit is connected to the controller through signals, and the controller and the information feedback module are both connected to a display through signals. The tire tread depth detector 4 is connected to the controller, and one end of the controller receives the detection information of the tire tread depth detector 4 through signals, and the detection information includes the detection distance from the tire tread depth detector 4 to the tire. The controller can adopt the Xinjie XD5-32T4 PLC controller.

[0041] Specifically, the cross-linear motion module 3 is connected to the tire tread depth detector 4, and the cross-linear motion module 3 is used to drive the tire tread depth detector 4 to move laterally and longitudinally in the detection area, so that the tire tread depth detector 4 can perform detection along the tire cross section, and can perform multiple detections at multiple positions along the tire cross section.

[0042] The controller is connected to the tire tread depth detector 4 through the general control unit, and is used to receive the detection information of the tire tread depth detector 4. The general control unit collects and analyzes this information, and then transmits the analyzed data to the controller and the display. While being able to effectively and detailedly display the data information, the controller and the cross-cross linear motion module 3 are connected by signals, and the cross-cross linear motion module 3 can be operated according to the results of data analysis during detection, and timely and accurate information detection can be performed. At the same time, the detection process and results are sent to the display, which is used to display the detection information results in real time, and the detection process is clearer and more definite.

[0043] Specifically, the detection information detected by the tire tread depth detector 4 can be the distance size obtained by the distance sensor. The pattern detection is to detect the depth of the pattern, which is used to reflect the wear condition of the tire. Therefore, the data information of the tire pattern is obtained by the distance sensor to determine whether the depth of the pattern is within a reasonable value. Because when the truck stops at the detection area, the pattern groove does not necessarily stop exactly at the upper end of the pattern depth detector 4, so it is necessary to move the position of the pattern depth detector 4 multiple times and scan the results to avoid missed detection.

[0044] The data obtained by the detection device will be transmitted one by one to the main control unit for data collection, analysis and feedback, and then the information will be transmitted to the controller, which will collect, analyze and process it to draw relevant conclusions. The conclusions will be transmitted to the cross-linear motion module 3 and the display. While displaying the data, the cross-linear motion module 3 will be adjusted to the corresponding position according to the detected data, and the tire will continue to be tested in detail.

[0045] The data transmission between the controller and the display can be carried out through a transmission line or a wireless transmission module, and the content of the display can also be transmitted wirelessly to the cloud, mobile phone, or other electronic display devices, which is convenient for data recording and organization. It can also retrieve multiple detection data of the same customer at different times on mobile devices such as mobile phones and tablets, giving customers a better service experience.

[0046] The controller is connected to the distance sensor and the position sensor through the general control unit to receive the detection information of the tire tread depth detector 4. The general control unit collects and analyzes this information, and then transmits the analyzed data to the controller and the display. While being able to effectively and detailedly display the data information, the controller and the cross-crossed linear motion module 3 are connected by signals, and the linear motion module 3 can be driven according to the results of the data analysis during the detection, and timely and accurate information detection can be performed. At the same time, the detection process and results are sent to the display together, which is used to display the detection information results in real time, and the detection process is clearer and clearer. While displaying the data, the cross-crossed linear motion module 3 is adjusted to the corresponding position according to the detected data, and the tire is continuously tested in detail, which can be more intuitive and detailed during the detection. Through this system, the tread depth information of the truck tire can be detected quickly and conveniently, avoiding the time-consuming manual detection and possible omissions, and the detection is faster and more convenient.

[0047] The number of tire tread depth detectors 4 is at least four, and each detection unit 100 is provided with two tread depth detectors 4. Two contour lines can be obtained by scanning along the axial direction of the automobile, which can improve the detection efficiency.

[0048] As an optional implementation, the detection device also includes a crossbeam 6, which divides the opening of the groove 2 into two detection areas 21. The two detection areas 21 are arranged in sequence along the direction of travel of the vehicle to be detected. This can increase the range of the detection area, and the driver can park the car with a larger range, thereby avoiding increasing the difficulty of parking due to the limited tire position range being too narrow. Simply increasing the opening of the groove will cause the tire to sink more after reaching the detection area. After adding the crossbeam 6 in the middle, the opening is divided into two detection areas 21, and the width of each detection area 21 will not be particularly large, so that the tire will not sink too much when passing through, and the driving smoothness will be better.

[0049] As an optional embodiment, a tire cleaning device is provided on the base 1 .

[0050] A tire cleaning device is provided on the base 1 to clean the tire before testing to ensure the accuracy of the measurement data.

[0051] On the other hand, the present invention provides a detection method, using any of the above detection devices to detect the wear of automobile tire tread, the method comprising the following steps:

[0052] S1, the car drives above the detection device, and the tire to be detected corresponds to the opening of the groove 2;

[0053] S2, the tread depth detector 4 moves along the first direction driven by the motion module 3 to obtain tread depth data of multiple sections perpendicular to the tire axis;

[0054] S3. The tread depth detector 4 moves along a second direction perpendicular to the first direction driven by the motion module 3 to obtain tread depth data of multiple axial sections of the tire.

[0055] It should be noted that:

[0056] The automatic detection device for truck tire tread wear provided in some embodiments also includes a camera for photographing the vehicle's license plate number, appearance, etc., so as to facilitate the server to record and retrieve multiple detection results of the vehicle at different time periods;

[0057] Some embodiments provide an automatic detection device for truck tire tread wear, further comprising a server, which is connected to the controller and is used to record and store each detection condition of the truck, so that the owner can have a certain understanding of the tire wear and tear of the vehicle, and can roughly understand how long the vehicle tire can continue to be used based on periodic data collection, so as to avoid tire failure in advance. Therefore, the owner can view the existing detection data table of the vehicle at any time and any place when there is a network.

[0058] The detection device can detect multiple wheels on the same axis at one time, so if a truck has more than four tires (i.e. more than two rows), the purpose of detecting multiple tires can be achieved by moving the vehicle forward multiple times.

[0059] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
