In order to facilitate the user's understanding of the inventive concept of the present invention, the following description will exemplify the detection process of the detection apparatus with a tire.
As shown in fig. 6, the supporting seat 103 of the detection device 1 is abutted against the surface of the tire 2, then the detection device 1 is started by the start button 106, the control unit 50 controls the optoelectronic component 201 to emit a light beam to the tire 2, the image acquisition device 30 acquires an image emitted by the optoelectronic component 201 onto the tire 2 and transmits the acquired image to the control unit 50, and the control unit 50 performs an operation process according to the image transmitted by the image acquisition component 202 and obtains the wear state of the tire 2.
In some embodiments, when the optoelectronic device 201 is placed in the first receiving cavity 104, a central axis of a light beam emitted by the optoelectronic device 201 is at a right angle to the supporting base 103.
In some embodiments, in order to improve the detection effect, a straight line formed by projecting the light beam emitted by the optoelectronic assembly 201 to the brake disc or the tread is parallel to the central axis of the brake disc or the tread.
Referring to fig. 7, the detecting apparatus 1 further includes an illuminating device 31, and the code reading unit 30 includes a fixing frame 301, a camera module 302, and a lens 303. The camera module 302, the lighting device 31 and the lens 303 are all mounted on the fixing frame 301, and the fixing frame 301 is disposed on the handheld housing 10. The camera module 302 and the lighting device 31 are electrically connected to the control unit 50. The illumination device 31 is used for illuminating the position of the code on the tire, and the camera module 302 is used for acquiring the image of the code on the tire. The lighting device 31 and the lens 303 are oppositely arranged on the fixing frame 301, and the lens 303 is used for matching with the fixing frame 301 to seal the lighting device 31 in the handheld housing 10, so that the lighting device 31 is prevented from being polluted, light emitted by the lighting device 31 is reduced, and the camera module 302 is prevented from capturing images.
Specifically, in the embodiment of the present invention, the number of the lighting device 31 and the number of the lens 303 are two, the fixing frame 301 is provided with two mounting grooves 3011 and two unthreaded holes 3012, the unthreaded holes 3012 are located between the two mounting grooves 3011, the two mounting grooves 3011 are symmetrically arranged on two sides of the unthreaded hole 3012, the lighting device 31 is fixed to the fixing frame 301, the camera module 302 corresponds to the unthreaded holes 3012, one lighting device 31 is mounted in one mounting groove 3011, and one lens 303 covers a notch of one mounting groove 3011. Therefore, the brightness of the illumination device 31 irradiating the code on the tire area is ensured, the situation that the left brightness and the right brightness of the image acquired by the camera module 302 are inconsistent can be avoided as much as possible, and the accuracy of the analyzed code information or vehicle information is further ensured.
Further, the camera module 302 includes a zoom lens. Referring to fig. 8, since the wheels 2 have different sizes, and the sizes of the areas of the encoded information attached to the tires 2 are different due to the different sizes of the tires 2, the distances from the detecting device 1 to the tires 2 are different when the encoded information of the tires 2 is recognized by the encoded reading unit 30, and the zoom lens can focus the encoded information of the tires by zooming. When the code reading unit 30 transmits the focused tire information image to the control unit 50, the control unit 50 analyzes the code information image to obtain corresponding information of the tire 2, such as: tread width, aspect ratio, meridian, hub size, load index, speed and DOT information of the tire (manufacturer, manufacturer information, wear index, traction index, high temperature resistance index, load bearing quality, tread wear index, etc.), then the control unit 50 transmits the corresponding information of the tire 2 to the display unit 60 for the user to check, and simultaneously the control unit 50 stores the tire information, and after the detection device 1 detects the brake disc or the tread, the information of the tire 2 is combined to perform calculation and analysis to obtain an accurate tire wear condition, so as to judge whether the brake disc or the tire 2 needs to be replaced, and transmit the tire wear condition and judgment information to the display unit 60 for the user to check.
In an embodiment of the present invention, the field of view of the image capture assembly 202 is smaller than the field of view of the code reading unit 30. The image acquisition assembly 202 has a centralized view range to improve the acquisition accuracy of the light-containing image, and the code reading unit 30 has a wider view range to adapt to different ranges of codes on different tires printed on the tires.
In some embodiments, the lighting device 31 is separate from the holder 301, and the lighting device 31 is fixed to the hand-held housing 10.
For the feedback unit 40, the feedback unit 40 is disposed in the handheld housing 10, and the feedback unit 40 is electrically connected to the control unit 50. After the control unit 50 performs the operation processing on the image transmitted by the image acquisition component 202, the control unit 50 controls the feedback unit 40 to output a prompt message.
Specifically, the feedback unit 40 includes a vibration motor (not shown) and a buzzer (not shown), and both the vibration motor and the buzzer are electrically connected to the control unit 50. Wherein the vibration motor prompts a user to perform different operation steps by generating vibration and the buzzer buzzing, such as: the vibration of the vibration motor represents that the contact surface of the detection device 1 with the brake disc or the tread is poor, the contact position of the supporting seat 103 with the brake disc or the tread needs to be adjusted again, and the buzzer sends out buzzing to represent that the detection is not finished but the supporting seat 103 is separated from the brake disc or the tread.
The detecting device 1 further includes a display unit 60, and the display unit 60 is electrically connected to the control unit 50 and the code reading unit 30. The display unit 60 and the optoelectronic component 201 are oppositely arranged on two sides of the handheld housing 10, namely: the display unit 60 is disposed on one side of the hand-held housing 10, and the optoelectronic assembly 201 and the image capturing assembly 202 are disposed on the other side of the hand-held housing 10.
