Definitions

  • the present invention can be included in the technical field of tyre tests, as well as in that of measuring arrangements characterized by using optical means by projecting a pattern and it refers in particular to an apparatus that, by means of a tape comprising sensors and cameras, allows analysing a tyre surface so as to diagnose wear and damage caused by objects incrusted therein or cracking.
  • the scanner is a device based on the scanning devices and method under the principle established in patent number US7313264B2.
  • the manual device has an elongated shape and is similar to those shown in patent numbers US8526067B2 and USD77165S, with the difference that this is horizontal and is provided with buttons to make a zoom.
  • the manual device also comprises a screen the operation of which is similar to that described in patent number USD754663 with the difference that this allows realizing in a screen a zoom or close-up of an image taken with the camera so as to determine the magnitude of the crack or object, and also having LED lighting which turns on during the inspection process upon detection of an object.
  • the invention also comprises a flexible tape capable of adopting several shapes so as to adapt to the type of tyre, unlike that described in patent number US6539789B1 .
  • the semi-rigid tape with which the scanning process is performed comprises a plurality of sensors for detection of different types of objects, and a plurality of cameras for obtaining images thereof. The sensors and cameras will be placed along the surface of the tape.
  • the present invention refers to a portable, electronic and computing device, scanning a tyre surface so as to detect irregularities. It uses a scanning method by means of sensors and cameras placed on a tape, which can be adapted to the tyre shape.
  • the portable scanner sends the image of the detected object to a screen, so that it is analysed by making a zoom. Also the portable scanner is provided with LEDs which, by means of a colour code, turn on upon detecting the type of object found on the tyre surface.
  • the device comprises a portable casing inside of which there is the wind-up tape and an electronic device for image recognition and treatment, as well as a battery, preferably of the rechargeable type.
  • the casing is also provided with at least one screen for displaying the obtained images by means of the imaging devices, operating controls and means for modifying the magnitude of the image shown on screen, in a zoom-like manner.
  • lighting means is foreseen, preferably LED lighting, linked to the recognition device, which turns on when the sensors detect any irregularity on the tyre surface.
  • the main object of the present invention is to provide a mechanism for tyre inspection and diagnosis, which allows performing said diagnosis in situ, without dismounting the tyres from the vehicle they are attached to.
  • Figure 1 shows an upper perspective view of the portable scanner object of the invention.
  • Figure 2. shows a detailed view of the tape being deployed, wherein the cameras and sensors can be seen as being linked to the surface thereof.
  • Figure 3. It shows a view of the scanner use for determining the state of the tyre surface.
  • the portable scanner for tyre damage diagnosis being described, schematically shown in figure 1 , comprises an outer casing (1 ) inside of which a flexible and deployable tape (2) is wound.
  • the casing (1 ) has an upper face (3) and a handle (4) for manual gripping.
  • FIG. 1 illustrates a front view of the tape (2) being deployed, which shows it comprises a plurality of sensors (10) and at least one camera (1 1 ).
  • Figure 3 illustrates the use of the portable scanner for tyre damage diagnosis, which shows that it is not necessary to dismount said tyres in order to inspect them.
  • the cameras (1 1 ) progressively send the images to screen (5) that can be inspected by an operator who, in case of requiring observation of any element in more detail, can activate the zoom (7) for magnifying the image.
  • the sensors (10) send a signal to the lighting means (8) for them to activate and emit a flashing light as a warning.

Abstract

La présente invention concerne un appareil ou un dispositif électronique et informatique qui balaye une surface de pneu pour détecter des irrégularités, sans nécessiter un démontage de celui-ci à partir du véhicule sur lequel il est installé. L'invention utilise un procédé de balayage au moyen de capteurs et de caméras placés sur une bande, qui peut être adaptée à la forme du pneu. Le dispositif de balayage portatif envoie l'image de l'objet détecté à un écran pour qu'elle soit analysée au moyen d'un grossissement. Le dispositif de balayage portatif comprend également des DEL qui, au moyen d'un code couleur, s'allument lors de la détection de l'objet trouvé sur la surface du pneu.
