Definitions

  • the invention relates to a sensor, and more particularly to a tire pressure monitoring sensor. Background technique
  • Vehicle Tire Pressure Monitoring System monitors tire pressure, temperature, etc. in real time while driving or stationary by installing a highly sensitive sensor on each tire, and wirelessly transmits it to the receiver built into the central monitor.
  • the central monitor displays the above data on the display or alerts the driver in the form of a beep, etc., and alarms when the tire leaks and the pressure changes beyond the safety threshold (the threshold can be set by the display) to ensure driving Safety.
  • sensors There are two types of sensors currently in use, one is an inactive type sensor, that is, the sensor case is fixed and cannot be moved, so that it is difficult to adapt to different wheel requirements when installed; the other is a movable type sensor, the sensor The sensor housing can be rotated around the central axis of rotation, so that it can meet the installation requirements of different specifications of the hub, but this sensor can not be automatically adjusted, and when the vehicle is running, it is easy to lift upwards under the centrifugal force of the hub, thus affecting Tire handling and tire safety. Disclosure of invention
  • the object of the present invention is directed to the deficiencies of the prior art, and provides a tire pressure monitoring sensor, which adopts a movable sensor housing, and can automatically adjust the activity of the sensor housing by rotating a nut, thereby realizing automatic installation and positioning.
  • a tire pressure monitoring sensor includes a sensor housing, a screw, a nut mated with the screw, and a gasket abutting the hub mounting hole, the sensor solid Positioned in the sensor housing, one end of the screw passes through the sensor housing, and the sensor housing is movably connected to the screw through a rotating central shaft, a valve rod is fixed at the screw port, and a sliding is disposed on the sensor housing a sloped surface, the valve rod abuts on a sliding slope of the sensor housing and forms a contact line A sliding diametric surface that is straight to the sliding slope and passes through the contact line is located between the central axis of rotation and the surface of the shell hub.
  • one end of the valve rod contacting the sliding slope is arc-shaped, and the valve is capped with a valve cap.
  • a circular arc-shaped spacer is disposed between the gasket and the sensor housing, and the gasket is in close contact with the sensor housing.
  • the shape of the circular arc-shaped gasket matches the circular arc-shaped edge of the sensor casing, so that it fits tightly together, thus not only increasing the support strength of the gasket, but also supporting the gasket to closely fit the hub surface to ensure that it The tightness of the joint.
  • Figure 1 is a schematic view of the overall structure of the present invention.
  • FIG. 2 is a schematic illustration of the mounting of the present invention on a hub. The best way to implement the invention
  • a tire pressure monitoring sensor includes a sensor housing 8 and a screw 9 .
  • the screw 9 is sleeved with a valve.
  • a cap 1 a nut 2 mated with the thread 9 , a gasket 4 abutting against the hub mounting hole 10
  • the sensor 7 is fixed in the sensor housing 8

  • a circular arc-shaped metal gasket 5 is disposed between the gasket 4 and the sensor casing 8, and the gasket 5 is in close contact with the sensor casing 8.
  • the specific principle of the present invention is that the screw 9 has a force F1 on the valve rod 6 when the nut is tightened.
  • the technical effect of the present invention is: Since the sensor is a built-in sensor, when one end of the screw passes through the hub mounting hole, a nut is screwed onto the screw. When the nut is tightened, the screw is caused by the function of the hub.
  • the valve stem fixed at the screw port exerts a force on the sliding bevel provided on the sensor housing that it contacts, since the sensor housing is movably connected to the screw through a rotating central shaft
  • the sliding diameter surface perpendicular to the sliding slope and passing through the contact line ie, the contact line formed by the valve rod abutting on the sliding slope
  • the shell hub ie, the sensor housing is fitted to the hub
  • the valve stem will exert a downward force on the sensor housing (ie, the force acting in the direction of the shell hub), forcing the sensor housing to move downward, through the continuous tightening of the nut
  • the sensor housing can be continuously pressed down, and finally the sensor housing and the hub are closely attached to meet the tire loading and unloading. Convenience.

Abstract

Capteur de surveillance de la pression des pneumatiques comprenant un corps (8) de capteur pivotant, une vis (9) dont une extrémité traverse ledit corps (8) de capteur qui est relié pivotant à la vis (9) par un axe central rotatif (11), un écrou (2) qui est couplé à ladite vis (9) et une plaque d'étanchéité (4) qui est installée sur un trou de montage (10) du moyeu (14) de roue. Le capteur est fixé dans le corps (8) du capteur. L'extrémité filetée (9) de la vis est couplée à demeure à un corps de valve de gonflage (6). Le corps (8) du capteur comporte un plan de glissement incliné (12). Le corps de valve de gonflage (6) vient buter contre ledit plan de glissement incliné (12) du corps (8) de capteur pour former une ligne de contact. Une surface de glissement radial verticale par rapport au plan de glissement incliné (12) traverse la ligne de contact et s'étend entre l'axe central rotatif (11) et une surface de liaison corps-moyeu (13). La position du corps (8) de capteur peut être ajustée automatiquement par le vissage dudit écrou (2).
