    Car disc brake pad wear detection device
    The present invention relates to a brake pad wear detection device of a vehicle. Specifically, when a pad of a brake is worn over a certain amount, a warning means is operated so that a driver can take immediate action and display the wear level of the brake pad. The present invention relates to a brake pad wear detection preventing device for allowing a driver to frequently check and recognize a wear state of a brake pad.
    As shown in Fig. 1, the conventional disc brake 10 is provided with hydraulic cylinders 11a and 11b respectively on the left and right sides of the disc 15 and attached to the pistons 12a and 12b of the hydraulic cylinders 11a and 11b. The piston rods 13a and 13b were operated to the disk 15 side, but the pads 14a and 14b opposed to the disk 15 were attached to the ends of the piston rods 13a and 13b.
    The conventional disc brake 10 transfers the hydraulic pressure generated when the brake is operated to the hydraulic cylinders 11a and 11b to move the pistons 12a and 12b of the hydraulic cylinders 11a and 11b to the disc 15 side. As a result, the pads 14a and 14b attached to the piston rods 13a and 13b were brought into close contact with the disk 15 to stop the rotating disk to obtain braking force.
    However, such a conventional disc brake 10 is caused to wear the pads (14a, 14b) due to the frequent use of the disc brake 10, at this time, if more than the appropriate amount of wear occurs because the braking force is greatly reduced pads (14a, 14b) ) To secure safety by immediately replacing, but the driver can not accurately detect this, there was a high risk of a safety accident because the braking force of the disc brake 10 is lowered before the replacement time.
    Therefore, the present invention has been made to solve the above problems, the purpose is to display the wear level of the disc brake pad of the vehicle, the driver can easily recognize the wear level of the pad from time to time, the wear of the pad proceeds more than a certain amount When the warning means is activated by the driver to recognize the immediate action to ensure a good braking force always to provide a disc brake pad wear detection device of the vehicle to suppress the occurrence of safety accidents.
    In order to achieve the above object, the present invention installs a piston sensor in a hydraulic cylinder, and attaches a distance sensor to the pad attachment plate of the cylinder rod, while connecting the piston sensor and the distance sensor to the ECU, It is a basic feature of the technical configuration that the display is connected to the output unit and the warning means.

    An embodiment of the present invention configured as described above will be described in detail with reference to the accompanying drawings.
    As shown in Figs. 1 and 2, the disc brake 10 is provided with hydraulic cylinders 11a and 11b on the left and right sides of the disc 15, respectively, and a piston rod 13a formed on the piston of the hydraulic cylinders 11a and 11b. And plates 16a and 16b having pads 14a and 14b attached to 13b, and the pads 14a and 14b are opposed to the left and right surfaces of the disk 15.
    The detection unit 20 installs the piston sensor 22 on the pistons 12a and 12b and installs the distance sensor 23 on the piston rods 13a and 13b so as to face the disk 15. The sensor 22 and the distance sensor 23 are connected to the ECU 21, but the display 24 and the warning lamp 25 are connected to the output terminal of the ECU 21, and the piston sensor 22 is separated from the distance. The switch 27 is installed between the detection sensors 23, and the battery 26 is connected to the piston detection sensor 22.
    Referring to the operation of the present invention as follows.
    The operation of the pistons 12a and 12b in the hydraulic cylinders 11a and 11b causes the pistons 12a and 12b to move to the disk 15 side, at which time the piston sensor 22 senses this and inputs it to the ECU 21. At the same time, the distance sensor 23 detects the distance from the disk 15 and inputs it to the ECU 21. At this time, the input value is analyzed by the ECU 21 and the current pads 14a, 14b) displays the degree of wear, and when a certain amount of wear is applied to the warning light (25) so that the driver can recognize it immediately replace the pads (14a, 14b).
    As described above, the present invention senses the position of the hydraulic cylinder and the distance between the pad and the disk to display the wear level of the pad in the ECU, so that the driver can easily recognize the current wear level of the pad as well as the ideal amount of the pad. In case of abnormal wear, the warning means is activated so that the driver can immediately change the pad to maintain good brake performance at all times to suppress the occurrence of safety accidents.
