The present invention relates to a displacement sensing device for vehicle pedals. More specifically, the present invention relates to a displacement sensing device for a vehicle pedal, and more specifically, it is capable of accurately and reliably detecting the rotational displacement of a pedal provided in a vehicle and rotated by the driver's operation. In particular, the cost is reduced by simplifying the assembly components. It relates to a displacement sensing device for vehicle pedals that can achieve savings and improved productivity, and can secure waterproofness through a completely sealed structure.

Typically, vehicles are equipped with pedals that the driver operates and rotates, such as a brake pedal and a clutch pedal.

Below, the brake pedal will be explained.

The rear of the vehicle is equipped with a stop lamp (so-called brake lamp) that helps in safe driving by alerting the rear driver's attention. The stop lamp is activated by the stop lamp switch when the driver of the vehicle steps on the brake pedal. It is designed to light up when activated.

In addition, these days, awareness of vehicle braking safety is becoming more and more important, and a separate sensor is provided to detect the displacement of the brake pedal. The displacement detection sensor of the brake pedal detects the driver's signal when the driver presses the brake pedal. The intention to brake is immediately transmitted as an electrical signal to the vehicle's braking system, thereby maximizing the vehicle's braking safety performance.

However, vehicles up to now have had the disadvantage of requiring separate installation space for the stop lamp switch and displacement detection sensor, which operate in conjunction with the operation of the brake pedal, and a separate wire harness (electrical/signal wiring) for the vehicle.

In order to solve these conventional problems, the applicant of the present invention proposed a "displacement detection sensor for a brake pedal with a stop lamp switch function" in Korean Patent Publication No. 10-2012-0024131.

Looking at the displacement detection device for the brake pedal proposed in the above patent (hereinafter referred to as 'conventional'), a protrusion 39 is provided on the shaft tube 31 of the pedal 9 to form a locking portion 39a, and the locking portion 39a is formed. A rod 11 is formed from the portion 39a so that its center coincides with the rotation axis 33 of the pedal 9, and a sensor housing 1 is installed on one side of the rotation axis 33 of the pedal 9. Constructed, the end of the rod (11) is coupled to be inserted into the sensor housing (1), and the end of the rod (11) is connected to the locking member (27, 29, 5) formed on one side of the sensor housing (1). The magnet 7 is configured to rotate, and the sensor housing 1 is configured with a hall sensor 15 to detect the rotating magnet 7.

In this displacement detection sensor, when the pedal 9 operates, the locking portion 39a protruding from the rotation shaft 33 rotates, and when the locking portion 39a rotates, the end of the rod 11 rotates, and the rod 11 When the end of rotates, the magnet (7) rotates, and when the magnet (7) rotates, the hall sensor (15) is configured to detect the rotation of the magnet (7).

However, the displacement detection sensor described above has the following problems.

First, there is a problem that the number of parts that make up the displacement sensor is large and the connection relationship is complex, which causes manufacturing difficulties and increased costs.

Second, when used for a long period of time, the rod may be separated or damaged, and the rod and magnet may not be restored properly, which reduces operational reliability.

Third, as a contact-type connection means that directly transmits the rotation of the pedal to the sensor, there is a problem in that it does not reliably ensure smooth operation, noise prevention, and operating feel.

Accordingly, the applicant of the present invention came up with the present invention to solve the problems of the displacement detection sensor described above.

Republic of Korea Patent Publication No. 10-1197417 (announced on November 5, 2012) Republic of Korea Patent Publication No. 10-0980936 (announced on September 7, 2010) Republic of Korea Patent Publication No. 10-1438609 (announced on September 5, 2014) Republic of Korea Patent Publication No. 10-1536196 (announced on November 20, 2015) Republic of Korea Patent Publication No. 10-2160633 (announced on September 29, 2020)
