Description

Brake light sensor module < RTI ID = 0.0 >

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a brake system, and more particularly, to a brake light sensor module that detects whether a brake is operated to turn on a brake light in a brake operation.

When the vehicle's brake is activated, the brake light is turned on so that the brake operation can be recognized from the outside.

Conventionally, a method has been known in which a sensor is mounted on a master cylinder to detect a movement of an input element that operates in conjunction with a depression of a brake pedal, thereby lighting a brake light.

Here, the input element is formed in a capsule shape. Specifically, the input element includes a rod-shaped magnet having one side and the other side formed in the same shape and having different polarities, and a housing accommodating the magnet therein.

Therefore, the operator performs a process of assembling the magnet and the housing such that the magnet is stably received in the housing before the input element is installed in the master cylinder.

However, it is practically impossible for the operator to distinguish the polarity of the magnet by the external shape only by one side and the other side of the magnet being formed in the same rod shape, so that the input element accommodating the magnet, The sensor is malfunctioning due to its operation in the cylinder, and furthermore, the lighting of the brake light is not operated correctly, leading to a safety accident of the vehicle.

Meanwhile, in order to solve the above-mentioned problems, prior to assembling the magnet and the housing, an additional process of distinguishing the polarity of the magnet has been performed.

However, due to the additional process for distinguishing the polarity of the magnet, the work process is complicated, the working time is increased, the productivity is lowered, and the cost is increased.

Illustratively, the elastic member 10 can be applied as a coil spring.

The brake light sensor module includes a signal generating portion 20 elastically supported by the elastic member 10 and a rod 30 supporting the signal generating portion 20 from another direction.

The signal generating unit 20 is disposed in the insertion hole 110 of the master cylinder 100 together with the elastic member 10 and is supported on one side by the elastic member 10 and on the other side by the rod 30 .

The signal generating unit 20 is a element for generating a signal capable of operating a sensor 40 to be described later. Specifically, the signal generating unit 20 includes a magnet 21 having one side and the other side having different polarities, And a container 23 having a receiving space 23a corresponding to the magnet 21 and accommodating the magnet 21 therein.

On the other hand, the rod 30 is supported by the retainer 60 moved together with the power piston (not shown) in accordance with the depression of the brake pedal to support the signal generating unit 20.

That is, the rod 30 is disposed between the signal generating portion 20 and the retainer 60 to pressurize and support the signal generating portion 20 toward the elastic member 10 in response to the depression of the brake pedal.

The brake light sensor module includes a sensor 40 mounted on the master cylinder 100 and operated by the signal generating section 20. [

The sensor 40 is a component for generating a signal for turning on the brake light and is mounted on the master cylinder 100 to detect the position of the signal generating unit 20, that is, the position of the magnet 21, And outputs a corresponding signal to turn on the brake light.

[ Therefore, a support protrusion 215, which is supported on the inner surface of the container 23, may be formed between the body portion 211 and the release portion 213.

4, the mold releasing portion 213 is formed by being recessed inward along the longitudinal direction of the body portion 211 from one end of the body portion 211, The inner diameter and the recess depth may be smaller than the outer diameter of the body portion 211 and the entire length of the body portion 211. [

That is, by forming the protruding or depressed portion 213 on one side of the body 211 constituting the magnet 21, the shape of one side and the other side of the magnet 21 becomes different, The operator can easily distinguish the polarity of the magnet 21 without performing any separate work for polarity classification.

On the other hand, the container 23 is formed in an inner shape so that the deformable part 213 can be received therein, so that the magnet 21 can be assembled only to one side.

Meanwhile, the air enclosing space 23b in which the air remaining in the accommodating space 23a is concentrated can be formed inside the receiving body 231 without being discharged to the outside when the magnet 21 is inserted.

Therefore, even when the magnet 21 is inserted into the accommodation space 23a, the magnet 21 can be stably received in the accommodation space 23a without being pushed outward by the reaction force of the compressed air.

Further, the separation preventing protrusion 2311 may further include an air vent hole 2311a communicating with the air confining space 23b.
