Embodiment Construction

[0036] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0037] In order to solve the troublesome operation of the current wired equipment, and the technical problem of being unable to accurately and effectively judge the location of the abnormal noise of the vehicle.

[0038] The invention provides a device for wirelessly detecting abnormal noise of a vehicle, comprising:

[0039] A piezoelectric ceramic sensor, the piezoelectric ceramic sensor converts the received vibration into an electrical signal;

[0040] A clamping part, the clamping part is installed on any part of the vehicle where abnormal noise is suspected, and the piezoelectric ceramic sensor is arranged in the clamping part;

[0041] An FM transmitter, the...

Abstract

The invention provides a device for wirelessly detecting abnormal sound of a vehicle, and the device comprises a piezoelectric ceramic sensor which converts the received vibration into an electric signal; a clamping component installed on any part, suspected to have abnormal sound, of the vehicle, wherein the piezoelectric ceramic sensor is arranged in the clamping component; a FM transmitter used for receiving the electric signal and amplifying the electric signal, wherein the FM transmitter outputs the amplified electric signal as an audio signal, and the FM transmitter is fixed on the clamping part; and a vehicle-mounted radio used for receiving the audio signal and judging the part where the abnormal sound is located according to the frequency corresponding to the abnormal sound of the vehicle-mounted radio. The problem that an existing wired detection device needs to pull a lot of long wires into a cab and is unsafe is solved. Meanwhile, the problem of misjudgment caused by the fact that various abnormal sounds exist at the same time and the abnormal sounds fed back by a maintainer and a vehicle owner are not from the same source due to the fact that the used earphone is operated by a single person is solved.

Description

technical field [0001] The invention relates to the technical field of vehicle abnormal sound detection, in particular to a device and method for wirelessly detecting vehicle abnormal sound. Background technique [0002] For a long time, with the aging of the vehicle, various parts of the car have begun to produce various abnormal noises, especially on the chassis. Some abnormal noises need to be produced during the driving process of the vehicle. It has always been a troublesome problem for the maintenance industry. Things have always been judged by experience or replacement parts. [0003] In the past few years, the maintenance industry has made some progress, and a kind of abnormal sound detection equipment has begun to appear, but the effect of use is not satisfactory. [0004] 1. For wired ones, it is unsafe to pull a lot of long wires into the cab. [0005] 2. For multiple abnormal noises at the same time, because the earphones used are operated by one person, the ab...
