Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a pedal anti-

The present invention relates to a pedal anti-skid device capable of preventing a driver from being injured when a pedal is pushed to a driver's side when a vehicle collides.

Generally, when a vehicle collides, the pedal (brake pedal or clutch pedal) is pushed toward the driver. At this time, there is a problem that the pedal pays the driver's leg while the brake pedal is pushed in together.

Recently, there have been proposals of prior art documents using a variety of methods for preventing injury caused by the jumping of the pedal. The prior art documents largely prevent the brake pedal frame itself from being pushed into the driver's side, or even if the brake pedal frame is pushed in, the pedal can not be pushed into the driver's side, or even if the brake pedal is pushed in, There have been proposed ways to lose power.

In order to lose the price ability of the pedal itself, the pedal may be bent using the articulating part, the pedal itself may be released, the buffer may be applied by applying hydraulic pressure or pneumatic pressure, or a spring may be applied to provide elasticity , And the like.

As a method of folding the pedal using the joint, the Korean Patent Registration No. 10-0657586 (hereinafter referred to as "conventional") is most similar to the present invention.

19, 20, and 21), conventionally, the first bracket 120, the second bracket 130, the insertion protrusions 150e of the anti-skid unit 150, The first bracket 130 is engaged with the first bracket 120 and the first arm 150b of the anti-skid unit 150 is engaged with the first bracket 120. [ The sliding contact of the second bracket 130 causes the insertion protrusion 150e of the anti-skid unit 150 to be disengaged from the fourth insertion slot 140e of the brake pedal arm 140, The second arm 150c of the brake pedal arm 150 is pushed forward by pushing the upper portion of the brake pedal arm 140 forward.

The second arm of the anti-skid device 150 is configured to push the upper portion of the brake pedal arm 140 so that the driver's foot is pressed against the brake pedal 141 frequently, There was a fatal problem that the foot could not be escaped because the foot was stuck on the pedal.

In the prior art, the insertion protrusion 150e of the anti-skid device 150 and the fourth insertion groove 140e of the brake pedal arm 140 are coupled to each other, The break due to the break was unintentionally disengaged when the brake was applied more strongly than normal, such as a sudden stop, and the brake did not listen to it, thus causing a fatal problem causing a larger accident.

Korean Patent Registration No. 10-0657586.

In order to solve the conventional problems mentioned in the background art, the present invention improves the structure of the conventional pedal anti-jamming device so that the pedal is bent at the time of a collision to prevent the driver from being charged, And to provide a pedal jamming device capable of preventing the pedal from being bent.

In order to achieve the above object, the present invention provides a vehicle comprising: an upper arm hinged to a fixed shaft of a vehicle body at an upper middle portion thereof and hinged to a booster bracket at an intermediate portion of a rear portion thereof; And a second hinge shaft is provided at an upper middle portion of the upper hinge shaft so as to be slidably opened to the front lower portion in front of a lower portion of the upper arm, A lower arm for causing an axial groove to be hung rearward; A front surface of the upper arm is hinged to an upper front portion of the upper arm and a third hinge axis and a lower surface of the upper portion is hinged to the rear hinge axis, An operating arm provided with an axial groove and forwardly engaged with a second hinge axis of the lower arm and having a shear pin connected and fixed to an intermediate upper portion of the second hinge axis of the lower arm at an intermediate upper portion of the second axial groove; The upper rear portion is hinged to the third hinge shaft and the lower rear portion is formed to surround the first hinge axis and is cut by the engagement space of the second hinge axis and the shear pin, And the operating arm is configured such that when the pedal is pushed toward the driver in the event of a collision of the vehicle, the operating arm is brought into contact with the protruding surface of the third hinge shaft When the lower portion of the body rotates, the shear pin is cut, and when the shear pin is cut off, the lower portion of the body is continuously rotated while the second shaft is separated from the lower horn by separating the second shaft from the second hinge shaft, When the upper arm is pushed further toward the driver in a state of being separated from the lower arm, the first axial groove of the upper arm is separated from the second hinge axis of the lower arm so that the lower arm is separated from the upper arm And, when the lower arm is separated from the upper arm lower arm proposes to configure the free rotation about the first hinge axis.

According to the above-described means, since the middle of the pedal collapses at the time of collision, the lowering force of the pedal is lost, and the lower arm is in a free state in which the pressing force for pressing the foot is lost. Therefore, It is effective. In addition, the present invention can prevent abnormal breakage because the shear pin is not easily broken even if the brake is strongly pressed as in the case of a sudden stop because the break occurs due to the cutting method of the shear pin. This can prevent fatal accidents that may occur due to unexpected breakage of the brakes, thereby improving stability. Further, the present invention has a smooth effect of improving the sense of operation due to the configuration of the pad.

And specific descriptions of well-known and commonly-used techniques may be omitted to avoid obscuring the subject matter, or to be omitted or replaced with a simple code or name.

Below, 1  To 4  The present invention is described below with reference to the drawings.

As shown in the figure, the present invention includes an upper arm 1 hinged to a fixed axis A1 of a vehicle body at an upper middle portion thereof and hinged to a booster bracket A2 at a rear middle portion thereof; And a second hinge shaft 52 is provided at an upper middle portion of the upper hinge shaft 51 so that the upper arm 1 and the lower hinge shaft 51 are hinge- A lower arm (2) for hanging a first axial groove (11) opened obliquely to the front lower portion rearward of the lower front side of the lower arm (1); A contact surface 31 which comes into contact with the protruding surface A3 of the vehicle at the time of the collision of the vehicle is provided at the front upper portion and hinge-connected to the upper front portion of the upper arm 1 and the third hinge shaft 53 at the rear upper portion, A second shaft groove 32 is formed at an intermediate portion of the lower portion of the lower arm 2 so as to be sloped open toward the rear lower portion of the lower arm 2 so as to be hung in front of the second hinge shaft 52 of the lower arm 2, An operating arm (3) having a shear pin (54) connected and fixed to an intermediate upper portion of a second hinge shaft (52) of the second hinge shaft (2); The upper rear portion is hinged to the third hinge axis 53 and the lower rear portion is formed to surround the first hinge axis 51 and the second hinge axis 52 is formed to surround the first hinge axis 51. [ And a pad 4 made of a rubber material. The pad 4 has a plurality of frictional protrusions 41 formed on both surfaces thereof.

Hereinafter, the configuration of the present invention will be described in more detail.

2, the upper arm 1 is in the form of a plate, and the remaining lower arm 2, the operation arm 3, and the pads 4 are fitted on the front of the upper arm 1, Sectional shape is bent in a "C" shape.

1 and 2, the pad 4 is coupled to the front of the upper arm 1 in such a manner that the pad 4 is put on the front side of the upper arm 1. The operation arm 3 is coupled to the front side of the pad 4 The upper arm 1, and the operation arm 3 in such a manner that the lower arm 2 is covered. The upper arm 1, the lower arm 2 and the operation arm 3 are made of a metal material and the pad 4 is made of a rubber material. The metal material may be replaced with a synthetic resin having high strength, and the rubber material may be made of a soft synthetic resin having a friction, a buffering force, and a stretching force, or a similar material.

2, the shear pin 54 is inserted into one end face of a plate bent in a "C" shape of the lower arm 2 and the actuating arm 3, and is installed. When the shear pin 54 is installed on one end surface, the shear pin 54 can be cut more quickly and quickly than the shear pin 54 provided on both end surfaces of the shear pin 54. At this time, the material of the shear pin 54 is made of synthetic resin. If the shear pin 54 is formed of a synthetic resin, the cutting action is faster than that of the metal. The material of the shear pin 54 may be replaced with a material such as a metal, if necessary, and a cutting groove may be formed so that cutting is performed more quickly.

2, the friction protrusion 41 formed on the pad 4 serves to prevent the operation arm 3 and the lower arm 2 from slipping from the upper arm 1, and the pad 4 function to buffer the transfer force when the pedal of the lower arm 2 is depressed and transmit the buffered force to the upper arm 1 to improve the operation feeling.

3, the upper arm 1 is rotatable about the fixed axis A1 and the upper arm 1 is pushed by the booster bracket A2 when the pedal A of the lower arm 2 is depressed. And if the booster bracket A2 is pushed, although not shown, the booster cylinder can be operated to operate the brake or the clutch.

3, the upper arm 1 and the lower arm 2 are connected by a first hinge shaft 51, and the upper arm 1 and the operation arm 3 are connected to a third hinge shaft The lower arm 2 and the operation arm 3 are fixed by a shear pin 54 and the upper arm 1 is fixed by the engagement of the second axial groove 32 of the actuating arm 3 The lower arm 2 is fixed to the lower arm 2 by the engagement by the second shaft groove 32 of the operation arm 3 and the engagement by the first shaft groove 11 of the upper arm 1, The pad 4 and the upper arm 1 are connected by a third hinge shaft 53 and the pad 4 and the lower arm 2 are connected by a first hinge shaft 51 . Therefore, the upper arm 1, the lower arm 2, the operating arm 3, and the pads 4 are connected to each other and integrally fixed. The upper arm 1 is actuated when the pedal A of the lower arm 2 is depressed and the brake or the clutch can be operated according to the operation of the upper arm 1. [

Below, 5  The operation of the present invention will now be described with reference to FIG.

When the pedal A is pushed to the driver's side in the event of a vehicle collision, the operation arm 3 is rotated about the third hinge shaft 53 by the contact of the protruding surface A3 with the contact surface 31, The shear pin 54 is cut and the shear pin 54 is cut so that the lower end of the body is continuously rotated while the second shaft groove 32 is separated from the second hinge shaft 52 The upper arm 1 is separated from the lower arm 2 so that the upper arm 1 is pushed further toward the driver in a state in which the operating arm 3 is separated from the lower arm 2, The lower arm 2 is separated from the upper arm 1 by being separated from the second hinge shaft 52 of the lower arm 2. When the lower arm 2 is separated from the upper arm 1, Is free to rotate about the first hinge axis 51. [ Thus, according to the present invention, when the pedal A is pushed to the driver's side in the event of a vehicle collision, the lower arm 2 is free to rotate around the first hinge axis 51, Can be prevented from being worn.

Hereinafter, effects of the present invention will be described with reference to the entire drawings.

The upper arm (1) is connected to the booster bracket (A2). In the conventional structure, the lower arm 2 is connected to the booster bracket A2. In this case, even if the lower arm 2 rotates freely during the collision, the force applied by the booster bracket A2 causes the driver Causing the problem that the pricing power to price is not completely lost. However, when the upper arm 1 is connected to the booster bracket A2 as in the present invention, the price of the lower arm 2 can be completely eliminated at the time of a collision.

Further, the present invention has a structure in which the operation of the anti-skid means starts from the cutting of the shear pin 54 in the event of a vehicle collision. Conventional arrangements have a structure in which the anti-skid prevention means is started to operate the components such as the operation arm 3 in the event of a collision without the configuration of the shear pin 54. This method does not start the accurate anti- The operation arm 3 after the collision is in a state of pushing the pedal A, which causes a problem that the foot may be caught. However, the system according to the present invention has an effect that the pedal A is not likely to have a foot.

Further, the present invention has a structure in which the shear pin 54 is not cut even when the pedal A is pressed normally. 3, the pressing force of the pedal A is transmitted from the lower arm 2 to the upper arm 1 via the operating arm 3. At this time, when the operating arm 3 is in contact with the second arm 2 So that even if the pedal A is strongly depressed, the force acts to transmit the upper arm 1 without being transmitted to the shear pin 54. The second hinge shaft 52 and the shear pin 54 are close to each other and the third hinge shaft 53 corresponding to the center where the operation arm 3 is rotatable is provided at a long distance So that the sheer pin 54 is hardly cut unless the impact is extremely strong. This action has the effect of preventing an operation error due to the unintentional cutting of the shear pin 54.

Further, the present invention has a structure in which the shear pin 54 is cut only when the vehicle is hit. 3 and 5, the pressing force of the pedal A is not transmitted to the shear pin 54, and the force causes the working arm 3 to immediately rotate to cut the shear pin 54. More specifically, the contact surface 31 rotates about the third hinge axis 53 on the same principle as the leverage method. The rotary arm 3 can transmit a direct load to the shear pin 54, so that the shear pin 54 can be easily transferred. This cutting method is effective in preventing an operation error of the unintentional anti-skid means because the shear pin 54 is cut only when the vehicle is hit, and the anti-skid means operates.

Further, the present invention has a structure in which the anti-skid means is operated by the pad (4). 2 and 3, the pad 4 is in contact with the upper arm 1, the working arm 3 and the lower arm 2. This is because the force generated when the pedal A is depressed The upper arm 1 and the operation arm 3 can be transferred as they are. As a result, the entire device can be operated in an integrated manner, the unexpected cutting of the shear pin 54 can be more positively prevented, and a hard rubber material is inserted into the metal connection, Is improved.

Also, according to the present invention, the pedal A is capable of performing the function of re-assembling the rest of the components other than the sheer pin 54 even if the sheer pin 54 is broken after the collision. 5, the shear pin 54 after the collision is cut, the operating arm 3 is turned, and the lower arm 2 is folded. At this time, the shear pin 54 The upper arm 1, the lower arm 2 and the operation arm 3 can be reassembled in place and the frictional force of the pad 4 at the time of reassembly The pedal A is temporarily rendered ready for reuse. Such a function has an effect that the vehicle can be moved to a place for repairing.

Hereinafter, the application of the above-described configuration will be described.

It is most preferable that the present invention includes all of the above-described configurations, but it is possible to select only some of the configurations described above according to cost reduction, manufacturing convenience, or need. In addition, each of the above-described configurations may be independently applied to a technical field other than the technical field in consideration of the purpose, function, role, action, and the like.
