1 to 6, the inhibitor switch according to the present invention includes a housing 10, a terminal 20, a rotor 30, a speed change stage detecting portion, a cover 40, (50), a spring (60), and the like.

The upper portion of the housing 10 is opened, and is made of a synthetic resin material.

The terminal 20 is made of a metal material and includes a first terminal 21 and a second terminal 22.

The first terminal 21 and the second terminal 22 are mounted on the upper portion of the housing 10 in parallel to each other.

Unlike the prior art, there is no protrusion for raising the starting contactor 50 between the first terminal 21 and the second terminal 22 in the present invention.

The rotor 30 is made of a synthetic resin material and is rotatably mounted on the upper portion of the housing 10.

The rotor 30 has a plurality of through holes 34 through which the starter contactor 50 passes.

At this time, the through holes 34 may be formed in a closed loop shape or an open loop shape in which more than one side is opened.

In the present embodiment, the rotor 30 includes a central shaft portion 31, a wing portion 32, and a drive gear portion 33.

The center shaft portion 31 is rotatably inserted into the housing 10.

The wing portion 32 protrudes in a flat plate shape at a portion of the outer peripheral surface of the central shaft portion 31 and is disposed on the first terminal 21 and the second terminal 22.

The wing portion 32 is formed with the through hole 34 and the starting contactor 50 is in contact with the upper surface of the wing portion 32 or through the through hole 34.

The inclined surface 35 is formed in the through hole 34 in the rotating direction of the wing portion 32 so that the lower surface of the starting contactor 50 is rotated It is possible to easily pass through the through hole 34 by raising the inclined surface 35 or to be raised and lowered on the upper surface of the wing portion 32.

The driving unit 33 is formed along the outer circumferential surface of the central shaft portion 31 on the side where the wing portion 32 is not formed.

The driver unit 33 is engaged with the speed change detecting unit as described later.

The shift detecting unit senses the rotational angle of the rotor 30 and detects the gear range of the automatic transmission.

As shown in FIGS. 2 and 3, the shift detection unit includes a driven gear 83, a rotation identifier 84, and a sensing unit 85.

The driven gear 83 is rotatably mounted on a protruding rotation protrusion formed on the housing 10, and is arranged to engage with the driver unit 33.

The rotation identifier 84 is mounted on the driven gear 83.

The sensing unit 85 senses the rotation angle of the rotation identifier 84 mounted on the driven gear 83 and rotates together with the driven gear 83 to calculate the rotation angle of the rotor 30, Thereby detecting the gear position of the automatic transmission.

In this embodiment, the rotation identifier 84 is made of a magnet.

The sensing unit 85 includes a circuit board 86 fixedly coupled to the housing 10 and a rotation identifier 84 mounted on the circuit board 86 and rotated together with the driven gear 83. [ That is, a hall sensor 87 for sensing a magnet.

Therefore, when the rotor 30 is rotated, the driven gear 83 engaged with the drive unit 33 is rotated. As the driven gear 83 rotates, the rotation identifier 84 also rotates At this time, the hall sensor 87 senses the rotation identifier 84 made of a magnet and senses the rotation angle of the driven gear 83.

The gear ratio of the driven gear 83 and the driven gear unit 33 is determined based on the rotation angle of the driven gear 83 sensed through the hall sensor 87, The rotation angle of the rotor 30 can be calculated.

When the rotation angle of the rotor 30 is calculated, the circuit board 86 compares the rotation angle of the rotor 30 with the rotation angle chart of the rotor 30, and determines whether the speed change stage of the automatic transmission is any one of P, R, N, Or the like.

The cover (40) is disposed on the rotor (30) and is fixedly coupled to the housing (10).

Although the cover 40 may be made of a synthetic resin material, the first cover 41 and the second cover 42 are separately manufactured to be robust against temperature conditions in the present invention.

The first cover (41) is made of a metal material coupled to the housing (10).

The second cover 42 includes a second cover 42 made of synthetic resin and fixed to the lower surface of the first cover 41.

At this time, the second cover (42) is fastened to the first cover (41) by an insert injection or forced indentation method.

A seating groove 43 in which the starting contactor 50 and the spring 60 are inserted is formed in a lower portion of the second cover 42 in a downward direction.

The starting contactor 50 is made of a metal material and the cover 40 is movably mounted on a seating groove 43 formed in the second cover 42 in a lower detail.

The starting contactor 50 penetrates through the through hole 34 when the rotor 30 rotates or contacts the upper surface of the blade 32 in detail on the upper surface of the rotor 30, (21) and the second terminal (22) to allow or block the starting of the engine by electrically connecting or disconnecting the first terminal (21) and the second terminal (22).

More specifically, when the rotor 30 rotates, the starter contactor 50 contacts the first terminal 21 and the second terminal 22 through the through-hole 34, And connects the first terminal 21 and the second terminal 22 or blocks the first terminal 21 and the second terminal 22 by contacting the upper surface of the wing portion 32.

Preferably, when the speed change stage of the P or N is detected by the speed change stage detection unit, the starting contactor 50 penetrates through the through hole 34 to connect the first terminal 21 and the second terminal 22 The starting contactor 50 is disposed on the upper surface of the wing portion 32 so as to allow the first terminal 21 and the second terminal 22 so that the starting of the engine is suppressed.

In this embodiment, the starting contactor 50 is formed as one, and the through holes 34 are formed in two.

The spring 60 is disposed between the second cover 42 and the starting contactor 50 in the seating groove 43 so as to move the starting contactor 50 in a downward direction .

At this time, the buckling prevention protrusion 44 protruding downward from the second cover 42 and inserted into the spring 60 is formed on the inside of the seating groove 43.

As a result, the spring 60 can be prevented from being bent in the left-right direction when the starting contactor 50 rises and the spring 60 is compressed.

As described above, according to the present invention, since the starting contactor 50 and the spring 60 are mounted on the fixed cover 40 rather than mounted on the rotating rotor 30, It is possible to reduce the moment of inertia and the defective contact ratio when the rotor 30 rotates.

The lower surface of the starter contactor 50 is formed in an arc shape about a vertical direction of the rotation direction of the wing portion 32 so that the starter contactor 50 rotates in the through- So that it can be moved more easily to the upper surface of the portion 32.

A cleaning member 70 for wiping the upper surface of the first terminal 21 and the upper surface of the second terminal 22 may be mounted on the rotor 30.

The cleaning member 70 is preferably mounted on a lower surface of the wing portion 32 as shown in FIG. 8 (b).

The cleaning member 70 contacts the upper surface of the first terminal 21 and the upper surface of the second terminal 22 in contact with the first terminal 21 and the second terminal 22 when the rotor 30 rotates. It is possible to increase the contact ratio between the terminal 20 and the starting contactor 50 by making the top surface of the first terminal 21 and the second terminal 22 free from foreign substances.

An accumulation groove 36 is formed on the upper surface of the wing portion 32.

The accumulation groove 36 is formed along the projecting direction of the wing portion 32 protruded from the central shaft portion 31.

In the present embodiment, the accumulation grooves 36 are three and are disposed on the sides of the two through holes 34. [

The accumulation groove 36 is provided with a lower surface of the starting contactor 50 which is separated from the through hole 34 when the rotor 30 rotates and is lifted up to the wing portion 32.

In addition, foreign matter attached to the lower surface of the starting contactor 50 is received in the accumulation groove 36 by being dropped or scratched.

An outlet groove 37 communicating with the accumulation groove 36 is formed on the upper surface of the wing portion 32.

The discharge groove 37 is formed along the rotational direction of the wing portion 32.

In the present embodiment, the discharge groove 37 is formed in an arc shape at both ends of the accumulation groove 36.

The discharge groove 37 is a passage through which the foreign matter contained in the accumulation groove 36 moves. The foreign matter contained in the accumulation groove 36 flows through the discharge groove 37 due to the influence of wind due to the movement of the contactor, (37) by centrifugal force or the like due to the rotation of the contactor (30), and is not attached again to the lower surface of the contactor.

At this time, the discharge groove 37 is located at an upper portion which is not overlapped with the first terminal 21 and the second terminal 22 in the vertical direction.

That is, when viewed from above, the discharge groove 37 and the first terminal 21 and the second terminal 22 are spaced apart from each other without being overlapped with each other.

Even if the foreign material that has moved to the discharge groove 37 is dropped from the wing portion 32 along the discharge groove 37 because both ends or side faces of the discharge groove 37 are opened to the outside, May not be attached to the first terminal (21) and the second terminal (22).

The shift detecting unit may have a structure as shown in FIG.

9 is a perspective view and a cross-sectional view showing a modified structure of the shift detecting portion of the inhibitor switch according to the embodiment of the present invention.

As shown in FIG. 9, the driven gear 83 is rotatably mounted on the housing 10, and is arranged to engage with the driver unit 33.

To this end, a rotation protrusion 11 protrudes from the upper surface of the housing 10, and the driven gear 83 is rotatably mounted on the rotation protrusion 11.

The rotation protrusion 11 is elastically deformed by an external force so that the driven gear 83 is easily inserted into the rotation protrusion 11 and then the driven gear 83 So that it is not arbitrarily separated from the rotation protrusion (11).

A guide protrusion 12 protrudes from the upper surface of the housing 10 about the rotation protrusion 11.

The guide protrusions 12 are preferably formed in a ring shape, but may be formed in an arc shape or the like spaced apart as the case may be.

A ring-shaped guide groove 88 into which the guide protrusion 12 is inserted is formed on a lower surface of the driven gear 83.

Therefore, when the driven gear 83 is coupled to the rotation protrusion 11, the guide protrusion 12 is inserted into the guide groove 88.

Therefore, the driven gear 83 can be stably rotated in the horizontal direction around the rotation protrusion 11 when the driven gear 83 rotates.

In addition, the rotation identifier 84 is formed of a ring-shaped magnet and is adapted to inject inserts into the driven gear 83.

The rotation identifier 84 made of a magnet has N poles and S poles magnetized in the horizontal direction.

Therefore, when the driven gear 83 rotates, the sensing unit 85 can more easily detect the rotation angle of the rotation identifier 84.

Hereinafter, an operation process of the present invention having the above-described configuration will be described.

FIG. 7 is an explanatory view for explaining the position of the speed change stage and start contactor 50 of the inhibitor switch according to the embodiment of the present invention, and FIG. 8 is a view for explaining the position of the start contactor 50 of the inhibitor switch according to the embodiment of the present invention. (50) according to an embodiment of the present invention.

7 (a), 7 (b), 7 (c) and 7 (d) show the position of the gear position at the D-stage.

As shown in FIGS. 7 (a) and 7 (c), when the rotor 30 rotates and detects the P-stage or N-stage in the speed change stage detecting unit, And penetrates the hole 34 to contact the first terminal 21 and the second terminal 22.

Therefore, when the shift of the automatic transmission is at the P-stage or N-stage, the driver can start the engine.

7 (b) and (d), when the rotor 30 is rotated and the R-stage or D-stage is detected by the speed-change stage detecting unit, So that the first terminal (21) and the second terminal (22) can not contact the upper surface of the rotor (30).

As a result, when the shift of the automatic transmission is at the R-stage or D-stage, the driver can not start.

When the starting contactor 50 is in contact with the terminal 20 through the through hole 34 as shown in FIG. 7, the starting contactor 50 (see FIG. 8) Passes through the through hole 34 and contacts the terminal 20.

8 (b), when the rotor 30 is rotated for shifting of the speed change stage, the starting contactor 50 rides on the inclined surface 35 by the rotational movement of the rotor 30 The spring 60 ascends while compressing it.

Therefore, the lower surface of the starting contactor 50 comes into contact with the upper surface of the wing portion 32, and is blocked without contacting the terminal 20.

When the rotor 30 further rotates, the starter contactor 50 passes through the new through-hole 34 different from the through-hole 34 shown in FIG. 8 (a) .

8 (b), when the rotor 30 rotates, the cleaning member 70 mounted on the undersurface of the wing portion 32 contacts the first terminal 21 and the second terminal 22 so that the upper surface of the first terminal 21 and the upper surface of the second terminal 22 are cleaned so that no foreign substance is present on the upper surfaces of the first terminal 21 and the second terminal 22, It is possible to increase the contact ratio of the starting contactor (20) and the starting contactor (50).

As shown in FIG. 7, the start of the engine can be allowed or blocked according to the position of the speed change stage through the above-described operation process.

In the present invention, the upper surface of the rotor 30 and the lower surface of the starting contactor 50 are in contact with each other when the rotor 30 rotates. However, since the rotor 30 is made of a synthetic resin material, It is possible to prevent the lower surface of the metal plate 50 from being easily worn due to friction between the metals.

Since the rotator 30 is rotated only by the inhibitor switch of the present invention as described above, there are few individuals to be rotated compared to the prior art, so that the moment of inertia can be reduced and the rotating object is reduced, Can be significantly reduced.

The starting contactor 50 and the terminal 20 can be opened or closed during the rotation of the rotor 30 because the starting contactor 50 is moved up and down without moving in contact with the terminal 20. [ Wear of the metallic material due to friction can be reduced, and occurrence of vibration in the starting contactor (50) can be reduced, and generation of foreign matter by abrasion or the like can be minimized.

The inhibitor switch having the elevating type starting contactor of the present invention is not limited to the above-described embodiment, but can be variously modified and embodied within the scope of the technical idea of the present invention.
