The present invention relates to a pedal simulator device, and more particularly, to a pedal simulator device capable of reducing an operation error caused by restraining movement of a damper member attached to a stopper.

일반적으로 전동 브레이크장치(Brake-By-Wire System)는 기계적 연결 없이 전자제어되는 전동 캘리퍼를 이용해 제동을 이루는 방식이다.Generally, a brake-by-wire system is a braking system using an electronically controlled electric caliper without mechanical connection.

이러한 전동 브레이크 장치는 유압을 적용하지 않는 특성상 운전자가 느끼는 페달감(Pedal Feeling)이 낮으므로, 유압이 갖는 히스테리시스(Hysteresis)를 구현하여 운전자의 페달 조작감을 저하시키지 않는 페달 시뮬레이터(Pedal Simulator)를 적용한다.This electric braking device has a pedal feeling that the driver does not feel due to the nature of not applying the hydraulic pressure, so a pedal simulator that implements hysteresis of the hydraulic pressure and does not deteriorate the operation feeling of the driver's pedal is applied do.

페달 시뮬레이터는, 중첩된 스프링의 마찰 저항을 이용하거나, 전자석이나 영구자석의 자력을 이용하는 방식으로 구현한다.The pedal simulator is realized by using the frictional resistance of the overlapped springs, or by using the magnetic force of the electromagnet or the permanent magnet.

피스톤(20)과 연결된 하우징부(30)와, 하우징부(30)의 이동을 구속하는 스토퍼부(40) 및 페달 조작감을 부여하는 댐퍼부재(50)는, 원통 형상으로 형성된 케이스부(10)의 내측에 설치된다.A housing portion 30 connected to the piston 20, a stopper portion 40 for restricting the movement of the housing portion 30 and a damper member 50 for giving a pedal operation feeling are formed in a cylindrical case portion 10, As shown in Fig.

케이스부(10)의 일측(도 1기준 우측)에는 캡부재(12)가 설치되며, 이러한 캡부재(12)를 관통하여 피스톤(20)이 설치된다.A cap member 12 is provided on one side (reference right side in FIG. 1) of the case portion 10 and a piston 20 is installed through the cap member 12.

피스톤(20)은, 페달의 조작과 연동되어 좌우(이하 도 1기준) 이동되며 댐퍼부재(50)와 하우징부(30)를 이동시키는 기술사상 안에서 다양한 형상으로 형성될 수 있다.The piston 20 may be formed in various shapes within the technical idea of moving the damper member 50 and the housing part 30 by moving left and right (refer to FIG. 1) according to the operation of the pedal.

일 실시예에 따른 피스톤(20)은, 캡부재(12)를 관통하여 설치되는 연결로드(22) 및 연결로드(22)의 타측(도 1기준 좌측)에 연결되는 장착부재(24)를 포함한다.The piston 20 according to one embodiment includes a connecting rod 22 provided through the cap member 12 and a mounting member 24 connected to the other side of the connecting rod 22 do.

장착부재(24)는, 하우징부(30)의 일측 단부를 감싸며 설치되므로, 피스톤(20)과 함께 하우징부(30)도 이동된다.The mounting member 24 is installed so as to surround one end of the housing portion 30 so that the housing portion 30 is also moved together with the piston 20. [

하우징부(30)는, 댐퍼부재(50)가 장착되는 내측홈부를 구비하며 피스톤(20)과 같이 이동되는 기술사상 안에서 다양한 형상으로 형성될 수 있다.The housing portion 30 has an inner groove portion on which the damper member 50 is mounted and may be formed in various shapes within the technical idea of moving the piston 20.

일 실시예에 따른 하우징부(30)는, 원통 형상으로 형성되어 피스톤(20)에 일측이 연결되는 하우징몸체(32)와, 하우징몸체(32)의 외측 둘레를 따라 돌출되는 외측돌기(34)를 포함한다.The housing part 30 according to one embodiment includes a housing body 32 formed in a cylindrical shape and connected to one side of the piston 20 and an outer protrusion 34 protruding along the outer circumference of the housing body 32, .

하우징몸체(32)의 내측에는 장착홈부(36)가 형성되며, 이러한 하우징몸체(32)의 일측은 장착부재(24)에 접하여 차폐되며, 하우징몸체(32)의 타측은 스토퍼부(40)를 향하여 개구된다.One side of the housing body 32 is shielded against the mounting member 24 and the other side of the housing body 32 is connected to the stopper 40 Lt; / RTI >

하우징몸체(32)의 내측 중앙에는 수평방향(도 1기준)으로 가이드바(38)가 설치되며, 가이드바(38)의 일측은 장착부재(24)에 삽입되어 고정된다.A guide bar 38 is installed horizontally (refer to FIG. 1) in the inner center of the housing body 32, and one side of the guide bar 38 is inserted and fixed to the mounting member 24.

이러한 가이드바(38)는 댐퍼부재(50)를 관통하여 스토퍼부(40)의 내측으로 삽입되며, 피스톤(20)의 장착부재(24)와 함께 수평방향으로 이동된다.The guide bar 38 penetrates the damper member 50 and is inserted into the stopper portion 40 and is moved in the horizontal direction together with the mounting member 24 of the piston 20.

즉, 피스톤(20)에 일측이 고정되는 가이드바(38)는, 댐퍼부재(50)를 관통하여 스토퍼부(40)로 삽입되므로, 댐퍼부재(50)의 수평이동을 안내한다.That is, the guide bar 38, one side of which is fixed to the piston 20, is inserted into the stopper 40 through the damper member 50, thereby guiding the horizontal movement of the damper member 50.

하우징부(30)를 탄성 지지하는 스토퍼부(40)는, 케이스부(10)에 고정되며 피스톤(20)의 이동으로 하우징몸체(32)의 내측으로 인입되는 스토퍼몸체(42) 및 스토퍼몸체(42)와 하우징몸체(32)의 사이에 설치되어 하우징몸체(32)를 탄성 지지하는 탄성가압부재(48)를 포함한다.The stopper portion 40 elastically supporting the housing portion 30 is fixed to the case portion 10 and includes a stopper body 42 and a stopper body 42 which are inserted into the housing body 32 by the movement of the piston 20, And an elastic pressing member 48 provided between the housing body 32 and the housing body 32 for elastically supporting the housing body 32.

스토퍼몸체(42)는, 케이스부(10)의 타측에 고정되는 지지캡(44) 및 지지캡(44)에서 케이스부(10)의 내측으로 연장되는 지지부재(46)를 포함한다.The stopper body 42 includes a support cap 44 fixed to the other side of the case portion 10 and a support member 46 extending inside the case portion 10 from the support cap 44.

이러한 스토퍼몸체(42)의 형상은 "ㅏ"자 형상으로 형성되며, 스토퍼몸체(42)의 지지캡(44)과 하우징몸체(32)의 외측돌기(34)에 탄성가압부재(48)의 양측이 지지된다.The stopper body 42 is formed in a shape such that the stopper body 42 has a shape such that the stopper body 42 and the outer protrusion 34 of the housing body 32 are fixed to both sides of the elastic pressing member 48 .

코일 스프링을 사용하는 탄성가압부재(48)의 일측은 외측돌기(34)에 접하여 지지되며, 탄성가압부재(48)의 타측은 지지캡(44)에 지지된다.One side of the elastic pressing member 48 using a coil spring is held in contact with the outer projection 34 and the other side of the elastic pressing member 48 is supported on the support cap 44. [

이와 같은 탄성가압부는, 페달의 조작으로 피스톤(20)이 이동되는 경우, 피스톤(20)과 함께 이동되는 하우징부(30)를 탄성지지하므로, 외력이 제거된 하우징부(30)를 초기 위치로 이동시킨다. When the piston 20 is moved by the operation of the pedal, the resilient pressing portion elastically supports the housing portion 30 moved together with the piston 20, so that the housing portion 30 from which the external force is removed is moved to the initial position .

도 2 내지 도 4에 도시된 바와 같이, 하우징몸체(32)의 장착홈부(36)에 설치되는 댐퍼부재(50)는, 하우징부(30)와 함께 이동되어 스토퍼부(40)에 접하는 방향으로 이동된다.2 to 4, the damper member 50 provided in the mounting groove portion 36 of the housing body 32 is moved together with the housing portion 30 to be in contact with the stopper portion 40 .

이러한 댐퍼부재(50)는, 댐퍼부재(50)에서 돌출된 접착방지돌기부(60)가 스토퍼부(40)에 접하면서 압축되므로, 페달 조작감을 부여하는 기술사상 안에서 다양한 재질 및 형상으로 형성된다.The damper member 50 is formed in a variety of materials and shapes in a technique that imparts a pedal operation feeling because the anti-bonding protrusions 60 protruding from the damper member 50 are compressed while being in contact with the stopper portion 40.

일 실시예에 따른 댐퍼부재(50)는, 가이드바(38)가 관통되는 중공이 내측에 구비되는 원기둥 형상의 댐퍼몸체(52)와, 댐퍼몸체(52)의 외측으로 돌출되는 측면돌출부(54)를 포함한다.The damper member 50 according to one embodiment includes a cylindrical damper body 52 having a hollow inside which a guide bar 38 penetrates and a side protrusion 54 protruding outward from the damper body 52 ).

측면돌출부(54)는 댐퍼몸체(52)의 길이방향(도 4기준 좌우방향)으로 설치되며, 측면돌출부(54)의 원주를 따라 복수로 돌출되므로, 댐퍼부재(50)의 재료비를 절감하며, 구조강성을 보강한다.The side protrusions 54 are provided in the longitudinal direction of the damper body 52 and protrude along the circumference of the side protrusions 54 to reduce the material cost of the damper member 50, Strengthen structural rigidity.

스토퍼부(40)와 마주하는 댐퍼부재(50)에서 돌출되는 접착방지돌기부(60)는, 스토퍼부(40)와 댐퍼부재(50)를 이격시키므로, 댐퍼부재(50)가 스토퍼부(40)에 접착됨을 방지하기 위한 기술사상 안에서 다양한 형상으로 형성된다.Since the damper member 50 separates the stopper portion 40 from the damper member 50 by separating the stopper portion 40 and the damper member 50 from the damper member 50 facing the stopper portion 40, So as to prevent adhesion to the substrate.

일 실시예에 따른 댐퍼부재(50)와 접착방지돌기부(60)는 고무를 포함하여 성형되므로, 생산비를 절감하는 한편 자체 탄성을 가진다.Since the damper member 50 and the anti-sticking protrusion 60 according to the embodiment are formed by including rubber, the manufacturing cost is reduced and the elastic member has its own elasticity.

따라서, 댐퍼부재(50)와 접착방지돌기부(60)는, 압축에 의한 변형으로 페달의 조작감을 형성하는 한편, 외력이 제거된 상태에서는 원상태로 복원된다.Therefore, the damper member 50 and the adhesion preventive projection 60 form a feeling of operation of the pedal by deformation due to compression, and are restored to their original state when the external force is removed.

접착방지돌기부(60)는, 댐퍼부재(50)의 가압시 스토퍼부(40)와 댐퍼부재(50) 사이의 접착을 방지하기 위해, 댐퍼부재(50)에서 스토퍼부(40)를 향하여 복수 개의 지지돌기(62)가 돌출된다.The adhesion preventive protrusion 60 is provided on the damper member 50 toward the stopper portion 40 to prevent adhesion between the stopper portion 40 and the damper member 50 when the damper member 50 is pressed, The support protrusions 62 protrude.

일 실시예에 따른 지지돌기(62)의 개수는 3개이며, 이러한 지지돌기(62)는 원주 방향을 따라 서로 이격된 상태로 설치된다.The number of the support protrusions 62 according to one embodiment is three, and the support protrusions 62 are installed to be spaced from each other along the circumferential direction.

댐퍼부재(50)의 조립시, 접착방지돌기부(60)가 구비된 부분을 스토퍼부(40)를 향한 방향으로 조립하면 되므로, 댐퍼부재(50)의 일측에만 접착방지돌기부(60)를 형성한다.Since the portion of the damper member 50 that is provided with the adhesive preventing protrusion 60 can be assembled in the direction toward the stopper 40, the adhesive preventing protrusion 60 is formed only on one side of the damper member 50 .

이러한 접착방지돌기부(60)를 구성하는 지지돌기(62)의 높이는, 댐퍼부재(50) 전체길이의 2% 내외로 한다.The height of the support protrusion 62 constituting the adhesion preventive protrusion 60 is set to about 2% of the total length of the damper member 50. [

접착방지돌기부(60)의 길이가 댐퍼부재(50)의 전체 길이 대비 4% 이상인 경우, 페달의 조작감에 영향을 주게 된다.When the length of the anti-adhesion protruding portion 60 is 4% or more of the total length of the damper member 50, the operation feeling of the pedal is affected.

또한 접착방지돌기부(60)의 길이가 댐퍼부재(50)의 전체 길이 대비 1% 이하인 경우, 댐퍼부재(50)가 스토퍼부(40)에 접촉되는 현상이 발생한다.Also, when the length of the anti-adhesion protrusion 60 is 1% or less of the total length of the damper member 50, the damper member 50 contacts the stopper 40.

예를 들어, 59mm 길이의 댐퍼부재(50)에 지지돌기(62)의 최대 높이를 1.2mm로 한정하여, 지지돌기(62)에 의해 페달 조작감에 영향을 미치지 않도록 한다. For example, the maximum height of the support protuberance 62 is limited to 1.2 mm in the damper member 50 of 59 mm in length, so that the support protuberance 62 does not affect the pedal operation feeling.

지지돌기(62)가 댐퍼부재(50)에서 돌출되는 높이는 서로 다르게 형성되며, 이러한 지지돌기(62)의 개수는 3개가 바람직하다.The height at which the support protrusions 62 protrude from the damper member 50 is different from each other and the number of the support protrusions 62 is preferably three.

이때, 지지돌기(62) 3개의 높이는 모두 상이하게 하며, 이러한 지지돌기(62)의 높이는, 최대 1.2mm부터 0.3~0.4mm 의 높이 차를 둔다.At this time, the height of the three support protrusions 62 is different from each other, and the height of the support protrusions 62 is set to a height difference of a maximum of 1.2 mm to 0.3 to 0.4 mm.

지지돌기(62)의 높이를 서로 상이하게 함은, 정상적인 페달 조작감에 영향을 미치지 않으면서, 댐퍼부재(50)가 지지부재(46)에 접착됨을 방지하기 위함이다.The height of the support protrusions 62 is different from each other in order to prevent the damper member 50 from adhering to the support member 46 without affecting the normal pedal operation feeling.

즉, 지지돌기(62)가 스토퍼부(40)의 지지부재(46)에 접촉된 이후, 댐퍼부재(50)가 지지부재(46)에 접하여 발생하는 페달 조작감의 차이를 최소화하는 동시에, 댐퍼부재(50)가 스토퍼부(40)에 접촉됨을 방지하기 위함이다.In other words, after the support projection 62 comes in contact with the support member 46 of the stopper portion 40, the difference of the pedal operation feeling generated by the damper member 50 in contact with the support member 46 is minimized, (50) is prevented from coming into contact with the stopper portion (40).

이러한 지지돌기(62)의 역할은, 점착 방지 외에도, 고무를 재질로 하는 지지돌기(62)의 압축 시점에서 발생하는 충격감, 또는 반력감이 순간 높아지는 현상을 완화한다.The role of the support protrusions 62 alleviates a phenomenon in which, at the time of compression of the support protrusions 62 made of rubber, the impact feeling or reaction force feeling instantaneously increases in addition to the adhesion prevention.

또한, 지지돌기(62)의 높이가 서로 다르게 구성됨으로 인해, 지지돌기(62)의 압축 시점에서 지지돌기(62)가 순차적으로 압축되면서 지지돌기(62)의 압축으로 발생하는 충격감을 완화한다.In addition, since the support protrusions 62 are configured to have different heights, the support protrusions 62 are sequentially compressed at the time of compression of the support protrusions 62, thereby alleviating the impact caused by compression of the support protrusions 62.

이하에서는 첨부된 도면들을 참조하여 본 발명의 일 실시예에 따른 페달 시뮬레이터장치(1)의 작동상태를 상세히 설명한다.Hereinafter, the operating state of the pedal simulator apparatus 1 according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 1과 도 2에 도시된 바와 같이, 운전자가 페달을 밟으면, 피스톤(20)과 함께 하우징부(30)가 이동된다.As shown in FIGS. 1 and 2, when the driver depresses the pedal, the housing portion 30 is moved together with the piston 20.

하우징부(30)의 내측에 설치된 댐퍼부재(50)가 스토퍼부(40)에 접하는 방향으로 이동되며, 접착방지돌기부(60)의 지지돌기(62) 가운데, 높이가 가장 높은 지지돌기(62)부터 높이가 가장 낮은 지지돌기(62)까지 순차적으로 스토퍼부(40)의 지지부재(46)에 닿는다.The damper member 50 provided on the inner side of the housing portion 30 is moved in the direction in contact with the stopper portion 40 and the support protrusion 62 having the highest height among the support protrusions 62 of the anti- The support member 46 of the stopper portion 40 sequentially reaches the support protrusion 62 with the lowest height.

따라서, 지지돌기(62)의 높이차에 따라 순차적으로 가압이 이루어지면서 지지돌기(62)가 압축된다.Accordingly, the support protrusions 62 are compressed while being sequentially pressed according to the height difference of the support protrusions 62.

지지돌기(62)의 압축 이후에는 댐퍼부재(50)도 압축되나, 댐퍼부재(50)와 지지부재(46)의 사이에는 지지돌기(62)에 의해 미세한 틈이 생성되므로, 댐퍼부재(50)의 접착을 방지할 수 있다.The damper member 50 is also compressed after the compression of the support protrusion 62. Since the minute protrusion 62 is formed between the damper member 50 and the support member 46, Can be prevented.

스토퍼부(40)의 지지돌기(62)와 마주하는 댐퍼부재(50)의 전 면적을 100이라 가정하면, 스토퍼부(40)와 마주하는 지지돌기(62)의 면적은 2.5정도이므로, 이러한 지지돌기(62)가 순차적으로 스토퍼부(40)의 지지돌기(62)에 접하므로, 댐퍼부재(50)의 접착을 방지할 수 있다.Assuming that the total area of the damper member 50 facing the support protrusion 62 of the stopper portion 40 is 100, the area of the support protrusion 62 facing the stopper portion 40 is about 2.5, Since the protrusions 62 sequentially abut against the support protrusions 62 of the stopper portion 40, adhesion of the damper members 50 can be prevented.

상술한 바와 같은 구성에 의하면, 일 실시예에 따른 페달 시뮬레이터장치(1)는, 접착방지돌기부(60)가 댐퍼부재(50)에서 복수로 돌출되며, 접착방지돌기부(60)의 돌출되는 높이도 서로 상이하므로, 페달 조작감 형성에 영향을 주지 않으면서도, 댐퍼부재(50)가 스토퍼부(40)에 접착되어 발생하는 동작이상을 감소시켜 동작신뢰성을 향상시킬 수 있다.According to the above-described configuration, the pedal simulator apparatus 1 according to the embodiment has the plurality of the anti-bonding protrusions 60 protruding from the damper member 50, and the height of the anti-stick protrusions 60 It is possible to improve the operation reliability by reducing the operation abnormality caused by the damper member 50 adhering to the stopper portion 40 without affecting the formation of the pedal operation feeling.

또한, 페달 가압시 댐퍼부재(50)가 스토퍼부(40)에 접착되어 발생하는 동작이상 상황을, 고무를 재질로 하는 댐퍼부재(50)의 형상 변화만으로 방지할 수 있으므로, 생산원가를 절감할 수 있다.In addition, since the operation abnormal situation that occurs when the damper member 50 is adhered to the stopper portion 40 when the pedal is pressurized can be prevented only by the shape change of the damper member 50 made of rubber, .

본 발명은 도면에 도시된 실시예를 참고로 하여 설명되었으나, 이는 예시적인 것에 불과하며, 당해 기술이 속하는 분야에서 통상의 지식을 가진 자라면 이로부터 다양한 변형 및 균등한 타 실시예가 가능하다는 점을 이해할 것이다.While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.

또한, 자동차에 설치되는 페달 시뮬레이터장치를 예로 들어 설명하였으나, 이는 예시적인 것에 불과하며, 페달을 사용하는 다른 장치에도 본 발명에 의한 페달 시뮬레이터장치가 사용될 수 있다.Also, although a pedal simulator device installed in an automobile has been described as an example, the pedal simulator device according to the present invention can also be used in other devices using pedals.

따라서, 본 발명의 진정한 기술적 보호범위는 특허청구범위에 의해서 정하여져야 할 것이다.
