The specific embodiment
Below, in conjunction with the accompanying drawings, the utility model is described in detail.
As shown in Figure 1, the vehicle door lock that the utility model provides comprises outdoor handle unlatching arm 1, inner handle is opened arm 2, child lock control arm 3, inner handle power transmission arm 4 and installing plate 7, inner handle is opened arm 2 and inner handle power transmission arm 4 is rotatably connected on the installing plate 7, inner handle is opened arm 2 and is comprised pressure-bearing surface 2a, inner handle power transmission arm 4 comprises chute 4a and pressure-bearing surface 4b, child lock control arm 3 comprises pressure-bearing projection 5, outdoor handle is opened arm 1 and is comprised bearing plate 1a, the bearing plate 1a that outdoor handle is opened arm 1 cooperates with the pressure-bearing surface 4b of inner handle power transmission arm 4, and the pressure-bearing projection 5 of child lock control arm 3 is assemblied among the chute 4a of inner handle power transmission arm 4 and with the pressure-bearing surface 2a of inner handle unlatching arm 2 and cooperates.
Wherein, described door lock also comprises gangbar 6, and gangbar 6 can be pivotally attached on the installing plate 7 by various known modes, and under the preferable case, gangbar 6 is pivotally attached on the installing plate 7, as shown in Figure 1 by bearing pin 8.Gangbar 6 can be a different shape, as long as can realize stirring pressure-bearing projection 5,, and can be linear pattern as long strip-board shape, rod shape etc. along the chute 4a of inner handle power transmission arm 4 function to lower slider, can be bending type also, or have certain curve shape.Regardless of the geomery of gangbar 6, all should comprise pressure-bearing surface 6a that cooperates with the bearing plate 1a of outdoor handle unlatching arm 1 and the pressure-bearing surface 6b that cooperates with the pressure-bearing projection 5 of child lock control arm 3.
Under the preferable case, on the position that is rotationally connected with installing plate 7 of described gangbar 6 return spare is installed, and preferred, described return spare is installed between gangbar 6 and the bearing pin 8, is used to make gangbar 6 at the stressed initial position that rotates back into again after bearing pin 8 turns over certain angle.Described return spare can be for the various members that can make the gangbar return, and as helical spring, cylindrical spring, taper spring, torsion spring etc., preferred, described return spare is a helical spring.
Pressure-bearing projection 5 on the described child lock control arm 3 can be the projection of different shape and size, as cylinder, oval cylinder, tetragonal body etc., merges and can slide in chute 4a as long as can match with the chute 4a of inner handle power transmission arm 4.Under the preferable case, described pressure-bearing projection 5 is a cylinder.In addition, pressure-bearing projection 5 can be one, also can for along and two of being arranged side by side of the perpendicular direction of child lock control arm 3 length directions, perhaps can be size cylinder unanimous between the higher and lower levels, also can be size two sections different cylinders up and down.Mode and position that pressure-bearing projection 5 is connected on the child lock control arm 3 are conventionally known to one of skill in the art, and can decide as the case may be.
Under the preferable case, pressure-bearing projection 5 is two sections different cylinders about size cylinder unanimous between the higher and lower levels or the size.When pressure-bearing projection 5 was size cylinder unanimous between the higher and lower levels, as shown in Figure 1, inner handle was opened the pressure-bearing surface 2a of arm 2 and the pressure-bearing surface 6b of gangbar 6 matches with this cylinder respectively, from different angles masterpiece is used on the pressure-bearing projection 5.And when pressure-bearing projection 5 is the different up and down two sections cylinders of size, as shown in Figure 4, the pressure-bearing surface 2a that inner handle is opened arm 2 cooperates with one section cylinder, and the pressure-bearing surface 6b of gangbar 6 cooperates with another section cylinder, and two sections cylinders bear different active forces respectively.Under the preferable case, bigger near one section cylindrical size of installing plate 7.When pressure-bearing projection 5 is the different up and down two sections cylinders of size, can adopt various connected mode known in those skilled in the art to connect between two sections cylinders.
Below, the operation process of the vehicle door lock that the utility model is provided is described.At first, be under the state of unlatching in door lock locking and child safety lock, as shown in Figure 2, the pressure-bearing surface 6a of gangbar 6 cooperates with the bearing plate 1a that outdoor handle is opened arm 1, and the pressure-bearing surface 6b of gangbar 6 cooperates with the pressure-bearing projection 5 of child lock control arm 3.The pressure-bearing projection 5 of child lock control arm 3 is positioned at the child lock enable possition near the chute 4a top of inner handle power transmission arm 4, and on this position, the pressure-bearing surface 2a that inner handle is opened arm 2 does not contact with the pressure-bearing projection 5 of child lock control arm 3.Therefore, under this state, can't open arm 2 and promptly can't open car door by the car internally-opened handle by inner handle.
Subsequently, when opening car door, as shown in Figure 3 by the car external-open handle, outdoor handle is opened arm 1 and is swayed, make and lift on the bearing plate 1a,, so can drive gangbar 6 and rotate counterclockwise around bearing pin 8 because the pressure-bearing surface 6a of gangbar 6 matches with the bearing plate 1a that outdoor handle is opened arm 1.Because the pressure-bearing surface 6b of gangbar 6 matches with the pressure-bearing projection 5 of child lock control arm 3, therefore when pressure-bearing surface 6b pressed down, pressure-bearing projection 5 moved downward stressed chute 4a along inner handle power transmission arm 4.
When the action of opening car door by the car external-open handle is finished, as shown in Figure 4, the pressure-bearing projection 5 of child lock control arm 3 will reset under the effect of the pressure-bearing surface 6b of gangbar 6, and promptly the chute 4a along inner handle power transmission arm 4 moves downward the child lock fastening position.Under this state, pressure-bearing projection 5 residing positions can guarantee that inner handle opens the pressure-bearing surface 2a of arm 2 and match with pressure-bearing projection 5 and contact.Therefore, when opening car door by the car internally-opened handle, promptly inner handle is opened arm 2 when axle rotates counterclockwise, and will promote 5 motions of pressure-bearing projection.Because pressure-bearing projection 5 is assemblied among the chute 4a of inner handle power transmission arm 4, so inner handle power transmission arm 4 will be rotated counterclockwise around axle by drive.Thereby lift on the pressure-bearing surface 4b of inner handle power transmission arm 4, drive bearing plate 1a that the outdoor handle that cooperates with it opens arm 1 and lift on also, rotate so outdoor handle is opened arm 1, thereby make door-lock opening, car door opening.
In addition, owing between gangbar 6 and bearing pin 8, return spare is installed, therefore after the action of opening car door by the car external-open handle is finished, gangbar 6 will rotate back into initial position again under the effect of the screen resilience of return spare, as shown in Figure 5, promptly the pressure-bearing projection 5 of the pressure-bearing surface 6b of gangbar 6 and child lock control arm 3 is separated.
