Electronic unit for measuring operating parameters of a vehicle wheel, comprising an electronic module and an inflation valve
First Claim
1. An electronic unit for measuring operating parameters of a vehicle wheel, the electronic unit comprising:
- an inflation valve includinga valve body configured to extend through an orifice in a wheel rim, and comprised of a trunk and an abutment head against the rim, anda rigid hollow tube extending in a continuation of the abutment head;
an electronic module configured to be mounted in a slidable manner around the rigid tube; and
a securing system configured to secure the electronic module and the inflation valve in a locked position of said electronic module, the electronic module extending in a direct continuation of the abutment head of said inflation valve, the securing system comprisinga locking system including locking devices for relative locking in translation of the electronic device along the rigid tube, defining at least two positions of relative locking, each of the locking devices being configured to correspond to a preselected thickness of the rim to be equipped with the electronic unit,wherein the electronic device and the abutment head of the inflation valve comprise;
two complementary front faces configured to come into correspondence in the locked position of the electronic device, at a predetermined minimum distance from each other that is identical for all preselected thicknesses of rims to be equipped with the electronic unit, andoptical tracking devices configured to optically track a longitudinal position of the electronic device along the rigid tube, configured to permit verification of whether the distance separating the two complementary front faces, in the locked position of said electronic device, corresponds to the predetermined minimum distance, the optical tracking devices including at least one projecting lug extending in relation to the front face of one of the electronic device and the abutment head and having a length substantially greater than the minimum predetermined distance for the locked position of the electronic device, and a recess configured to accommodate an extremity of the lug, arranged opposite one another in the front face of the other of the electronic device and the abutment head.

Abstract
The electronic unit includes an inflation valve adapted to be secured to a wheel rim and including an abutment head against the rim, extending in the continuation of which are a rigid tube, an electronic module mounted in a slidable manner along the tube, and elements for the relative locking in translation of the module along the tube, defining at least two positions of relative locking, each adapted to correspond to a preselected thickness of the rim intended to be equipped with the unit. The module and abutment head include two complementary front faces adapted in order to come into correspondence at a predetermined minimum distance from each other that is identical for all the preselected widths of rims intended to be equipped with the unit. Optical tracking devices are provided to permit verification of whether the distance separating the two complementary front faces corresponds to the predetermined minimum distance.
