Electronic unit for measuring the operation parameters of a vehicle wheel including an electronic housing and an inflation valve
First Claim
1. A valve stem assembly, comprising:
- a valve body being constructed of a flexible material, the valve body defining a longitudinal bore extending therethrough; and
a rigid core disposed within and extending entirely through the bore, the core having at least one detent formed along a periphery of the core, the detent being configured to receive a locking member positioned outside of the bore and around the rigid core and including a locking insert configured to be inserted into the detent, the locking member being coupled to an electronic module that monitors a condition of a tire,wherein moving the locking insert of the locking member into the detent ensures at least a partial locking between the core to the electronic module.

Abstract
An electronic unit includes an inflation valve (2) designed to be attached to a wheel rim (J) and an electronic module (1) assembled with the inflation valve. The inflation valve includes a rigid tube (12) extending in the extension of the valve, on the periphery of which is formed at least one transversal detent (20, 21), and the electronic module is attached to a ring (15) slideably mounted around the rigid tube. A latch plate (22) having a locking tooth (24) for insertion into a transversal detent, is mounted on the electronic module with a capacity to travel between a locking position and an unlocking position, the latch plate being associated with elastic elements designed, in the absence of stresses, to exert a force maintaining the latch plate in its locking position, and, upon an action exerted on these elastic elements, to displace this latch plate to its unlocking position.

9. A valve stem assembly comprising:
-
a valve body being constructed of a flexible material, the valve body defining a longitudinal bore extending therethrough; and a hollow core disposed within the valve body, the hollow core being constructed of a rigid material and having an end portion extending through the bore, the hollow core having at least one detent formed along a periphery of the end portion of the core, the detent being configured to receive a locking member positioned outside of the bore and around the core and including a locking insert configured to be inserted into the detent, the locking member being coupled to an electronic module that monitors a condition of a tire, wherein moving the locking insert of the locking member into the detent ensures at least a partial locking between the hollow core to the electronic module, and the partial locking is effective to incline the electronic module with respect to a longitudinal axis of the hollow core at a non-right angle. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A tire pressure measurement system comprising:
-
a valve body being constructed of a flexible material, the valve body having a longitudinal bore extending therethrough; a core disposed within and extending through the bore, the core having at least one detent formed along a periphery of the core; an electronic module configured to measure tire pressure, the electronic module communicating with the core; and a locking member positioned outside of the bore and around the core and including a locking insert configured to be inserted into the detent, the locking member being coupled to the electronic module, the detent being configured to receive the locking insert of the locking member, wherein moving the locking insert of the locking member into the detent ensures at least a partial locking between the hollow core to the electronic module. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
