Title:
VEHICLE TIRE TEST DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/074077
Kind Code:
A1
Abstract:
Provided is a vehicle tire test device. The device comprises a TPMS sensor, an antenna matching network and a terminal antenna, wherein the TPMS sensor uses ASK/OOK/FSK transmission technology, and a data transmission rate is greater than 20 kbps; the TPMS sensor is connected to the terminal antenna by means of the antenna matching network; and the terminal antenna is an inflating valve, a metal base or a tire rim. A radio frequency data transmission rate is improved, so as to reduce a radio frequency transmission time of a sensor, thereby reducing the transmission power consumption; and a data transmission time is shortened, thereby achieving the aims of enhancing the penetrability of signal transmission and improving the radio frequency interference resistance performance. An inflating valve, a metal base or a tire rim is used as a terminal antenna, such that the length and area of the antenna are increased, the signal conversion efficiency is higher, and the transmission stability of a sensor on a whole vehicle is better; and the terminal antenna is located on an outer side of a tire body, such that an improvement in the strength of a wireless signal is facilitated, and it is easier to realize longer-distance wireless communication and to reduce a bit error rate when the transmitting power of a TPMS sensor is the same.
