Motor vehicle lock with pivotable lock assembly

Technical field

The present invention relates to a kind of motor vehicle lock with locking mechanism, the locking mechanism includes pawl and for locking this The lock claw of pawl.

Background technique

Motor vehicle lock, especially motor vehicle door lock generally include at least one jam plate or the lock housing with jam plate, and jam plate is logical It is often made of the metal being arranged in lock housing, locking mechanism is located on jam plate.Jam plate is commonly equipped with inlet slot to accommodate locking bolt. Locking mechanism includes the rotatable pawl for installing bolt.Locking mechanism also includes lock claw, and pawl can pass through the lock claw quilt Locking.

The pawl of motor vehicle lock usually has the fork-shaped inlet slot formed by load arm and latch arm, wherein motor vehicle door or The locking bolt of the wing, such as hood or luggage-boot lid enters the inlet slot when door or the wing are closed.Under the auxiliary of latch arm, Locking bolt then makes pawl turn to closed position from open position.If pawl arrived closed position, locked via lock claw In the position.Locking bolt cannot leave the inlet slot of pawl again, because it is supported arm prevention.The latched position is referred to as main locking Position.

Some motor vehicle locks have the second latched position, i.e., so-called pre-locked position.The purpose of pre-locked position be as The relevant door of fruit or the wing do not reach primary locking position in the down periods and then intercept the door or the wing.

Therefore, in pre-locked position, pawl is not completely closed.However, the open movement of pawl is prevented by lock claw.It will lock Pawl accommodates pawl region in the position and is therefore also been described as prelock.Finally, pawl is fully closed in primary locking position. Therefore, prelock is the transition state between opening state and main lock state, and is for security reasons arranged.

The shell for being connected to jam plate or lock housing protects lock assembly from external action.In motor vehicle door lock, motor vehicle lock It is installed to car door in this way: substantially can only see the inlet slot for installing locking bolt in the outside of motor vehicle door.By It is base closed in motor vehicle door, the external opening of the inlet slot of the inside as shell and motor vehicle lock usually will not be due to External environment influence such as moisture etc. and cause problem deserving of attention.But it is generable be, such as since the window of abrasion is close Sealing and there is rainwater and drain to the shell that inside motor vehicle door and therefore can also reach motor vehicle lock.In summer, such rain Water can also evaporate and cause in power door, i.e. the air humidity of the hull outside of motor vehicle lock increases.

In the case where sealing, it can throw into question and damage due to the permeability moisture in existing motor vehicle lock.But Additional rubber seal is provided to increase manufacturing cost.

" stretching out upwards " refers to that object stretches out outward or to the outside of housing exterior walls from shell.Upwards therefore correspond to Outside, i.e. the outer wall far from shell or shell.

Elevated portion in the fringe region that " sheath stretched out around access " refers to access, in hull outside or outer wall Or protrusion, it extends out or up, such as surround mountain valley similar to mountain belts.Sheath in a manner of wall-like by especially being formed, such as Wall-like protruding portion.

" being covered by the first lock assembly " refers to the first lock assembly with being especially parallel to the outside of shell or the outer wall of shell The sheath of the stretching is covered, is covered.

Since sheath stretches out upwards around access, is also covered by the first lock assembly, can particularly effectively resist moisture With infiltration of the water such as rainwater through access to shell for penetrating into shell.As long as the influx of the water on shell is more than discharge rate, Water on the outside of shell --- otherwise it can directly penetrate into the access --- is retained and stopped to a certain extent by sheath. Therefore settable rubber seal is as additional component.

Preferably, the sheath stretched out upwards fully or closely around access and/or the first lock assembly is completely covered and stretches Sheath out.It is possible thereby to obtain particularly preferred sealing effect.

In one embodiment, the first lock assembly and the second lock assembly together the closely adjacent shell at least three And/or most five not ipsilaterals.

Different sides refers to the side with different directions.Side is the inner housing surface of such as access.Therefore transversally Especially observe side in cross-section, process/comprising access axis and perpendicular to cross-sectional axis.

" close adjacent/neighbouring/adjacent " refers to two surfaces --- i.e. the surface of shell and first or second lock assembly Surface --- mutually directly (contact) and/or partly Two-dimensional Overlapping or extremely is obtained with very small spacing in two-dimentional dimension Few gap formed less than one millimeter, the gap is very narrow so that liquid water cannot flow through at normal atmospheric pressure, therefore due to Adhesion strength is maintained in gap.

Especially, shell and/or lock assembly are made of plastics.It therefore, can be special in the close adjacent position in two surfaces Do not resist infiltration or advance of the water in close clearance easily.Preferred gap width is 5/10ths millimeters of maximum, preferably It is 3/10ths millimeters maximum, it is most preferably 1/10th millimeters maximum.

Since the first lock assembly and the second lock assembly are at least three and/or most five different flank abutments of shell Together, this particularly effectively can prevent rain penetration into shell.

In one embodiment, different sides is oriented to be parallel with access axis in cross-section, at right angles to each other or Substantially right angle and/or continuously neighbouring.

Side is also possible to arc/arch or curved shape, therefore a straight line determines the slave arc or curve of side Starting point to the direction of arc or the terminal of curve, the side with another side at right angle or substantially at right angle and/or with another phase Adjacent side continuously abuts.

It is parallel to the cross section of access axis more particularly to passes through access axis and the cross section perpendicular to cross-sectional axis.

" continuous neighbouring " refers to a side especially directly close to adjacent side.Therefore, continuous adjacent is certain Side chain is formed in degree.

By the side oriented toward each other at right angle or at a substantially right angle, the water of infiltration must overcome weight at least once Power is mobile by gap, to enter the inside for the shell for constituting particularly preferred barrier.The side of continuous adjacent can produce especially It is mazy and/or intertexture and/or meander-shaped gap, this also particularly effectively resists water leaking-in and passes through certainly.Cause This generates particularly effective sealing effect without caoutchouc elasticity sealing element is arranged.

In one embodiment, the first lock assembly surrounds sheath and/or close together in outside from top with being in U-shape On at least three and/or most four housing sides.

The U-shaped come from above includes ' U ' of reversion.Therefore water is not only prevented by the first lock assembly in plateau by sheath Shell is penetrated into, but also plateau is flowed down by sheath on two side faces close together.Therefore close in no caoutchouc elasticity Particularly effective sealing effect is realized in the case where sealing.

In one embodiment, the second lock assembly is immediately adjacent at least one and/or most three sides of shell.Especially It is the additional water barrier that can be therefore formed on the inner surface of shell, can particularly effectively be sealed.
