Description

Motor vehicles are locked

The present invention relates to a kind of motor vehicles lock, and can be the lock suitable for door leaf, such as tail-gate or side door, or be applicable In automobile seat lock.

As it is known, such a lock includes the plate of typically metal, by means of the plate will lock for abut against door leaf or The edge of seat applies and is fixed to the edge, also including a shell being typically made up of plastic material, shell envelope Cover latch mechanism component.

The lock includes rotary latch, and the rotary latch is intended to be engaged with striker (coop é rer), and the striker is mounted It is to be protruded from fixed frame.For this purpose, the lock bolt is presented a notch, striker is nibbled when when closing door leaf or when positioning chair Conjunction (engage) is in the notch.The lock also includes a rotary pawl, and the rotary pawl is intended to lock bolt maintenance in closure Position, in this closing position lock bolt by striker maintenance.Therefore, when locking is closed, striker is on the side surface of the notch of lock bolt Slided along a path for being referred to as closed path, and the lock bolt is promoted in a rotative pattern.

Such lock is described in patent document EP1039079, the purpose is to improve on lock bolt and claw same plane Performance (tenue).

Positioned at lock bolt and the side of the mid-plane (plan moyen) of claw, the plate is not located at this side to one crosspiece, and The crosspiece by means of flange and screw order about the plate abut against moveable door leaf edge apply, therefore the crosspiece form to Make the barrier of the displacement of the mid-plane relative to the mid-plane of the claw of the lock bolt.

Additionally, a stop part being fabricated from a flexible material or striker packaging part () be generally located at so Lock in, all vibration frequencies when the vehicle is in movement are absorbed, or to the stopping (fin) when closing Enter row buffering.This stop part be located at the shell housing in, be fixed on crosspiece, and door leaf or seat lock be in close Position is closed, striker is abutted against the pressing of this striker packaging part, is removed stop, and deform under the compression of striker packaging part.

Additionally, generally there are one or more flanks on the shell, the flank is cast on the shell and quilt It is oriented substantially perpendicularly to the mid-plane of lock bolt.If shaking as the vehicle moves, then lock bolt and the one or more flank Contacted and be therefore retained in place in the mid-plane of lock bolt.

One known thickness of this striker packaging part, in the compression of the striker packaging part of the mid-plane parallel to lock bolt On direction and corresponding to the fastening part in this striker on crosspiece and the distance between closing position and striker touching position, It is about 9.5mm.But, it appears that such thickness result in the required pressure excessive when door leaf or seat is closed.

Therefore the reduction of this thickness can be considered as to reduce this closing force.However, striker in the notch of lock bolt, Compressed between striker packaging part and lock bolt, thus therefore the pressure to lock bolt be also reduced, and lock bolt is not kept well, Easily collided perpendicular to its middle planar movement and especially against metallic plate.

Additionally, the lock bolt is generally by coated with post forming material (materiau de surmoulage), the material is set It is calculated as reducing vibrations noise in movement and during shock is closed when vehicle.However, undergoing door leaf to increase this material The life-span of significant stress during closure, this material is often reinforced, and this causes its decrease to noise buffering effect.

The present invention solves these problems by proposing a solution, the program reduce lock bolt and metallic plate it Between contact and shock, and therefore reduce when lock close when and when lock it is in the close position when by lock bolt angular displacement (d é battement) noise that causes.

In order to accomplish this point, the present invention proposes a kind of motor vehicles lock, and the lockset has a plate and by the whole of the lock One shell of mechanism's sealing cover, the lock includes：One rotary latch, it is intended to be engaged with a striker, the striker quilt It is installed as being protruded from a fixed frame；With a rotary pawl, it is intended to striker maintenance in closing position, when closure is described The striker is slided along a path for being referred to as closed path on the side surface of lock bolt and promotes the lock bolt during lock, It is characterized in that：The side surface is inclined relative to the preceding surface of the lock bolt, the preceding surface of the lock bolt with towards the plate Orientation preceding opposing surface, at least Part I of the closed path, when close the lock when striker with before this The EDGE CONTACT on surface, the lock includes a striker packaging part being fabricated from a flexible material, and it is disposed in the shell In housing, striker described in the closing position in lock is crushed between striker packaging part and the lock bolt, and the shell is also comprising extremely A few flank, the flank is oriented substantially perpendicular to the mid-plane of lock bolt, wherein the striker packaging part has extremely A few extension, the extension is accommodated near the flank, and the thickness that the extension has is in the side of lock bolt The height of flank is extended upwardly beyond, to cause that the movement perpendicular to its mid-plane of lock bolt causes the compression of this extension, Without being contacted with the flank.

The present invention is given the credit to, striker applies contact force to lock bolt, and the one-component of the contact force is approximately perpendicular to the side Surface and orientation is upward, and lock bolt undergoes moment of torsion as a result, the moment of torsion promotes lock bolt upwardly toward shell.

During shaking, therefore lock bolt abuts the shell, and especially against the flank of shell.The shell is by plastics material Material is made, and caused noise is much smaller than caused by the shock to metallic plate.

Additionally, lock bolt does not collide metallic plate during shaking, but abut the extension of striker packaging part.This hardly leads Cause noise.

Preferably, the side surface is the preceding surface opposed with the plate relative to the lock bolt with less than 90 degree and big In or equal to 85 degree of overturning angle, and between advantageously this angle is spent 85 to 88.

Preferably, the striker packaging part is fixed on a crosspiece, and the crosspiece is located at the centre of lock bolt and claw The side of plane, the plate not be located at this side, and the crosspiece form prevent the lock bolt mid-plane relative to the claw The barrier of mid-plane displacement.

Advantageously, the thickness of extension protrudes about 0.4mm from the height of flank.

The present invention is more fully described below with reference to accompanying drawing, accompanying drawing only represents the preferred embodiments of the invention.

In the following description, for purposes of clarity, direction is such as " upward ", " down " will be to be considered merely as according to attached The orientation of figure, and lock can be positioned by different way on the rolling stock.

As shown in Figure 1, it is intended to which the motor vehicles lock for door leaf or seat includes that a unshowned plate and one should The shell 1 of whole mechanism's sealing cover of lock, the lock includes：One rotary latch 2, it is intended to be engaged with a striker 3, described Striker is installed to be from a fixed frame and protrudes；One rotary pawl 4, it is intended to the maintenance of striker 3 in closing position, with And, a striker packaging part 5 being fabricated from a flexible material, it is located in the housing of the shell, described in the closing position in lock Striker 3 is crushed between striker packaging part 5 and the lock bolt 2.

Therefore, the striker 3 on a side surface of the notch of lock bolt 2 along lock bolt 2 respective surfaces a quilt The path of referred to as closed path AA' is slided, and the striker packaging part is deformed by compression.

Preferably, striker packaging part is made up of nitrile rubber, it is therefore preferred to have more than the hardness of 50 Shore As, preferably It is about 70 Shore As.

The lock also includes a crosspiece 6, positioned at the side (plate is not located at this side) of lock bolt and the mid-plane of claw, And the crosspiece forms barrier of the mid-plane relative to the mid-plane displacement of the claw for preventing the lock bolt, such as specially Described in sharp document EP1039079, and striker packaging part 5 is fixed on this crosspiece 6, as shown in Figures 2 and 3.Striker Packaging part includes that an aperture 5A, a branch 6A of crosspiece 6 are inserted into the aperture.

This fastening part 5A, 6A constitute the fastening part of striker packaging part, can be according to the construction of lock and with the presence or absence of crosspiece And make it by different way.

Additionally, as shown in Figure 4, shell 1 includes a flank 1A, the flank is oriented substantially perpendicular to lock bolt 2 Mid-plane.According to prior art, this flank is intended to be held in place lock bolt 2 in shell.The some of this type can be used Individual flank.

An improvement of the invention, such known flank reduces in height, and striker packaging part 5 includes one Individual extension 5B, extension 5B are accommodated in flank 1A nearby and are more than the height of groove (rainure) on thickness, with So that the movement for being basically perpendicular to its mid-plane of lock bolt 2 causes the compression of extension 5A, without being contacted with flank 1A, such as scheme Shown in 5.Preferably, the big 0.4mm of height of the thickness of extension 5A than flank 1A.More generally, the thickness of extension 5B from The height of flank 1A about 0.4mm prominent to lock bolt 2.

In Fig. 1 it also shows that flank 1A is shortened about 0.6mm, and including an end section 1B, the end section quilt Be formed so that the end section is as often as possible inclined at its edge, at the same form triangle and in its relative positioning On the not section relative with flank 1A.Therefore, extension 5B is also equally inclined outward flange 5C including one, corresponding to this End section 1B.

However, this end section 1B of flank 1A can also be formed so that it in its edge tilt, while foring one Individual triangle and the not section relative with flank 1A on its relative positioning, as shown in Fig. 4,5 and 6, the wherein end region Plane of the plane of section perpendicular to flank 1A.Therefore, extension 5B includes a straight outward flange 5C, corresponding to this end section 1B。

Finally, this end section 1B of flank 1A can be neither in its edge tilt again not with respect to it relative to flank 1A Position incline, but one perpendicular to flank 1A and be in shape rectangle flank section.Therefore, extension 5B is also wrapped A straight outward flange 5C is included, corresponding to this end section 1B.

Alternatively, the flank 1C of narrower (fine) may reside in the top of the extension 5A of striker packaging part 5, such as Shown in Fig. 6 and 7, therefore the thickness of extension 5B changed.

The thickness of striker packaging part 5, its parallel to the striker packaging part of the mid-plane of lock bolt 2 compression direction It is upper and corresponding to the fastening part in this striker packaging part on crosspiece 6 and between closing position and the touching position of striker 3 away from From preferably about 8.7mm.

Striker packaging part 5 can include multiple extensions, all extension 5B described above, according to being positioned over the shell On flank 1A positioning.Especially, striker packaging part can have two extensions, and they are relative in striker packaging part Heart plane P is symmetrical.

As shown in figs, according to the present invention, (when the lock is closed, striker 2 abuts against the side to the side surface 2A of lock bolt Slide on surface) it is (the preceding surface 2B and 2C pairs, the preceding surface towards the orientation of plate 7 inclined relative to the preceding surface 2B of lock bolt 2 Put), at least Part I of closed path A-A', the striker 2 enters with the edge of surface 2B before this when the lock is closed Row contact.

Preferably, (the preceding surface 2A is fixed with towards the plate relative to the preceding surface 2A of the lock bolt for this side surface 2B To described preceding surface 2C it is opposed) inclined with the angle α less than 90 degree and more than or equal to 85 degree, and advantageously this angle α arrives 85 Between 88 degree.The specific yardstick of each different elements of the lock is more accurately depended on to the selection of this angle α.

Therefore, contact force F (power be basically perpendicular to side surface 2B) of the striker 3 on lock bolt 2 is oriented upward, and lock Door bolt 2 undergoes moment of torsion as a result, and the moment of torsion promotes lock bolt upwardly toward shell 1.

With the arrangement of prior art conversely, the lock bolt is collided not against metallic plate 7 during shaking, but is preferably against The extension 5B of striker packaging part 5 as described above.This hardly causes noise.

It should be noted that even if striker packaging part 5 is not equipped with such extension 5A, lock bolt 2 also abuts against shell 1, And especially against flank 1A.The shell is made up of plastic material, and the noise for being generated is much smaller than hitting to metallic plate 7 Hit what is generated, and the geometry for being exclusively used in reducing noise can be cast out by plastic material.
