The control unit 240 is configured to recognize the information of the brake disc or the tire based on the image.

In some embodiments, the image capturing assembly 222 includes a prime lens (not shown). Since the distance from the image capturing assembly 222 to the base 100 is fixed, the use of a prime lens can quickly capture an image formed by the light emitted by the photoelectric assembly 221 and irradiated on the brake disc or the tread surface.

In some embodiments, the first accommodating cavity 213 and the second accommodating cavity 214 are provided at a predetermined angle to achieve a better arrangement of a preset included angle between a central axis of a light beam emitted by the photoelectric assembly 221 provided within the first accommodating cavity 213 and an optical axis of the image capturing assembly 222 provided within the second accommodating cavity 214. The optical axis of the image capturing assembly 222 is at a preset angle to the central axis of the light beam emitted by the photoelectric assembly 221, so that the image capturing assembly 222 can better capture an image formed by the light emitted by the photoelectric assembly 221 and irradiated on the brake disc or the tread surface.

In some embodiments, the central axis of the light beam emitted by the photoelectric assembly 221 is at right angles to the first base body 110 when the photoelectric assembly 221 is placed in the first accommodating cavity 213.

In some embodiments, in order to enhance the checking effect, the light beam emitted by the photoelectric assembly 221 is projected onto the brake disc or the tread surface to form a straight line parallel to the central axis of the brake disc or the tread surface.

In some embodiments, since the tires have different sizes, and since different tires have different sizes and the sizes of the areas of the coded information attached to the tires are different, the distances of the check device 1000 from the tires are different when the code reading unit 230 recognizes the coded information of the tire.

When the code reading unit 230 transmits the tire information image to the control unit 240, the control unit 240 parses the coded information image to obtain the corresponding information of the tire, for example: the tread width, the aspect ratio, the meridian, the size of a used wheel hub, the loading index, the speed, and the DOT information of the tire (manufacturer, manufacturer information, wear resistance index, traction index, high temperature resistance index, load-bearing mass, and tread wear index, etc.), then the control unit 240 transmits the corresponding information of the tire to the display unit 250 for a user to view, and meanwhile, the control unit 240 stores the tire information; after the check device 1000 checks the brake disc or the tread surface, calculation analysis is performed in combination with information about the tire to obtain an accurate tire wear condition, so as to judge whether the brake disc or the tire needs to be replaced, and the tire wear condition and judgement information are transmitted to the display unit 250 for a user to view.
