Definitions

  • the invention is based on a locking device according to the preamble of the independent claims.
  • a rotary latch is brought into its closed position via a crank mechanism and a toggle lever arrangement.
  • This construction requires high engine power and a large number of individual components. Otherwise, a door that is motor-locked with this device can no longer be opened if the motor fails.
  • the locking device according to the invention with the characterizing features of the independent claims, in contrast, has the advantage of a wide range of functions with a simple construction and low-stress components. This makes the individual locks of the locking device lighter and smaller and the force to be applied by the motor is reduced to a minimum.
  • the locking device is also designed so that the vehicle can be mechanically opened and locked as usual, even if an electrical component fails, without the central locking function.
  • the embodiment according to claim 1 has the additional advantage that the door handles used to open the doors can be pulled through when the vehicle is locked and no forces are exerted on the internal components of the lock. This avoids an otherwise existing risk of breakage of the components involved.
  • the training according to independent claim 2 has the additional advantage that only the force to actuate one of the two unlocking levers must be applied simultaneously by the motor. This reduces the engine power by half compared to operating both levers at the same time.
  • the measures listed in the dependent claims allow advantageous developments and improvements of the locking device. It is particularly advantageous to mount movable catches on the unlocking levers, which are preferably arranged on bendable actuating arms. These can be brought into two different positions by the control segments of the control member, in which they can either be gripped by door handle levers connected to the door handles or in which they pass the drivers unaffected.
  • the operating arms have the advantage of being very light, so that only a small motor power is required.
  • unlocking levers and door handle levers on a common axis has the advantage that no additional friction occurs between unlocking levers and door handle levers when the door is opened. This ensures that the lock functions reliably and minimizes the force that the driver has to exert on the door handle.
  • the emergency locking and unlocking levers enable the affected door to be opened and closed even in the event of a motor failure or defect.
  • Figure 1 shows an interior view of a lock, with the motor, motor bracket and control member omitted for ease of understanding.
  • Figure 2 shows a view from the same perspective with the door handle lever omitted.
  • Figure 3 shows a side plan view of the same lock and
  • Figure 4 shows an interior view from viewing direction IV in Figure 2.
  • Figures 5 and 6 each show a control member for a front and for a front door of a motor vehicle with the arrangement of the control sectors.
  • Figures 7 to 9 show an unlocked lock.
  • Figure 10 shows a centrally locked lock.
  • Figures 11 and 12 show a lock with child lock, and Figures 13 and 14 show an anti-theft lock.
  • the emergency release is shown in FIG. 15 and the emergency release is shown in FIGS. 16 and 17.
  • the locking device provided for motor vehicles has door locks 10 which are assigned to the individual doors 11 of the motor vehicle.
  • a lock 10 is shown in simplified form, and a door 11 with a locking cylinder 12, outer door handle 13 and inner door handle 14 is shown schematically.
  • Each individual door lock 10 has a support plate 15, on which the inner functional parts of the lock are arranged.
  • Each door lock also includes a locking pin 16 which is arranged in the associated body-fixed door handle. The locking pin 16 engages when the door is closed 11 in a slot-shaped recess 17 of the support plate 15.
  • FIG. 1 This has two legs 21, one of which can optionally be locked with a blocking element 23 which can be rotated about an axis 22.
  • FIG. 1 an unlocked rotary latch is shown with the door open.
  • the blocking element 23 is always pushed into its latching position by a return spring 24, so that a closing blade 25 arranged thereon engages behind one of the legs 21 of the rotary latch 20 when the door is closed (cf. FIG. 2 and FIG. 12).
  • the legs 21 push the closing blade 25 of the blocking element 23 back, so that a snap-in is made possible.
  • the blocking element 23 can also be opened by actuating its arm 26, which is opposite the closing blade 25. This is done via two approximately congruent unlocking levers 27 and 28, which are rotatably arranged side by side on the axis 22.
  • the unlocking levers 27, 28 each have extensions 29 which bear against the arm 26. In its rest position shown in FIG. 1, the unlocking lever 27 or 28 bears against a stop 30.
  • the unlocking levers 27, 28 have joints 31 to which an actuating arm 32 for the outer door handle 13 and 33 for the inner door handle 14 is articulated within limits. On the actuating arms 32, 33 a protruding driver 34 is attached laterally.
  • two door handle levers 35 each associated with them are also pivotably mounted about the axis 22. Each of these door handle levers 35 has a driving lug 36 which cooperate with the driving members 34.
  • the door lock 10 has an emergency button which can be operated manually from the inside and which acts on an emergency locking lever 37.
  • an emergency locking lever 37 At its lock end is a switching pin 38 arranged, which interacts both with an emergency locking hook 39 of the outer actuating arm 32 and with a reset plate 40 on the door handle lever 35 for the inner door handle 14.
  • the door handle levers 35 are each urged by a tension spring 41 in the direction of the stop 30, pressing them against the associated unlocking levers 27, 28 when they strike a contact plate 42 with the stop 30.
  • a spiral spring 43 is arranged, the projecting arms of which are applied to the unlocking levers 27 and 28 and the actuating arms 32 and 33 in such a way that the actuating arms in FIG below to be pushed onto the axis 22.
  • FIG. 2 shows the further components of the door lock 10 which are not shown in FIG. 1 for reasons of clarity.
  • the door handle levers 35 are omitted.
  • the core of the door lock 10 is a control member 44 acting on the actuating arms 32, 33. This is rotatably held in a control member carrier 45.
  • the axis of rotation located perpendicular to the control member carrier 45 and the extension of the actuating arm 32 is denoted by 46.
  • the control member 44 has two control cams 47, 48 located next to one another.
  • the outer control cam 47 shown in FIG. 2 acts on the actuating arm 32 for opening the door from the outside.
  • the control member 44 also has a gear 49 which is arranged concentrically with the axis of rotation 46 and which meshes with the worm of a small electric motor 50.
  • the motor 50 is fastened on the control member carrier 45, which is pivotally mounted about an axis 51.
  • the control member carrier 45 has a holding arm 52 which projects beyond the control member 44 and which is in contact with a stop 54 on the by an emergency release lever 53 designed as an eccentric Support plate 15 is held.
  • the emergency release lever 53 is fastened to a pivot pin 55 which is mounted in a side wall 56 of the support plate 15 which is angled by 90 ° and can be rotated in the locking cylinder 12 by actuating a key 57 (cf. FIG. 1).
  • An eccentric 58 is further fastened to the outside of the side wall 56 with the pivot pin 55.
  • the eccentric 58 is shown with a lever arm 59, on which a rod 60 connected to the lock cylinder 12 is rigidly connected. The other end engages in an elongated hole 61 of a second lever arm 62 on the locking cylinder 12 (cf. FIG. 3).
  • the elongated hole 61 has the effect that the eccentric 58 is influenced only when the key 57 is turned to the right in FIG. 3 into the N position, but not when the key 57 is turned to the left in the I, II, III positions.
  • the eccentric 58 acts on a slide 64 guided on the support plate 15. Lifting the slide 64 releases the emergency locking lever 37.
  • FIG. 4 shows a side view of a lock 10 from viewing direction IV in FIG. 2, the side wall 65 of the support plate 15 being cut away.
  • the individual components visible there have already been explained in the previous figures.
  • the control cams 47 and 48 which act on the actuating arms 32 and 33, are particularly clearly visible here.
  • the control cam 47 is directed upward and lifts the actuating arm 32 so that the driving lug 36 on the door handle lever 35 for the outer handle cannot reach the driver 34. In this position of the control member 44, the door in question cannot be opened from the outside.
  • the control cam 48 is rotated downward, so that here the driving lug 36 of the door handle lever 35 can catch the driver 34.
  • the actuating arm 33 is taken along, so that the catch 20 is released.
  • control elements 44 for the driver's door and front door are shown in individual representations.
  • the control member 44 can be rotated in four different positions by the motor 50 in the direction of the arrow. It has four sectors 1 to 4, which are assigned control cams or not, depending on the locking function.
  • the control cam 47 for the outer door actuation covers the sectors 1 and 2.
  • the control cam 48 behind it in FIG. 5 for the inner door actuation only covers the sector 2.
  • the control element 44 'in FIG. 6 differs from the control element only in a different design of the control cam 48' 44.
  • the control cam 48 'for the inner door actuation covers not only sector 2 but also sector 3.
  • Opposing cams 47/48 are always designed and arranged in such a way that they do not both start in the same sector and, when the control member continues to rotate in the direction of the arrow, only one of them two actuating arms 32, 33 is raised simultaneously.
  • the same locking functions apply to the four sectors 1 to 4 for both control members 44, 44 '.
  • the locking function is determined by the sector which in the door lock 10 (see also FIG. 2) is directed slightly obliquely towards the top right onto the actuating arm 32 .
  • Sector 1 means "centrally locked", ie the outer door handles 13 are ineffective, all doors can be opened from the inside by pulling the inner door handles 14. If sector 2 is effective, the vehicle is "theft-proof", ie all door handles can be pulled ineffectively, none of the doors can be opened from the outside or from the inside.
  • "Child safety" is active in sector 3, ie front doors can be opened from the inside and outside, but the front doors can only be opened from the outside. In sector 4, all doors are “unlocked”, i.e. they can be opened both from the inside and outside by pulling the door handles.
  • Figures 7 to 9 show the locking function "unlocked", in which the sector 4 of the control elements is effective. Parts that may not be designated have the same reference numerals as in the previous figures.
  • the two actuating arms 32 and 33 are in the same position, their lower position, close to the control members 44. In this position, when the door handles 13, 14 or the door handle lever 35 are actuated, the catches 34 on the actuating arms 32/33 are gripped by the driving lugs 36 on the door handle levers 35 and pulled to the right, so that the respective unlocking levers 27, 28 move away from one another remove their stop 30. This is shown in FIG. 9 for internal actuation.
  • the extension 29 on the unlocking lever 28 presses the blocking element 23 down on its arm 26, so that the locking pawl 25 releases the catch 20. If the emergency locking lever 37 has possibly been actuated here, its arm carrying the switching pin 38 is pressed down by the reset plate 40.
  • Figure 10 shows the locking function "centrally locked", in which the doors cannot be opened from the outside. Only the lever position for external actuation is shown.
  • the control cam 47 is pivoted upwards as in FIG. 2, so that the sector 1 shown in FIG. 5 is directed towards the actuating arm 32.
  • the actuating lever 32 is raised so that the driving lug 36 does not reach the driver 34 and the door handle lever 35 can be pulled through between control cam 47 and driver 34 without resistance and ineffectively.
  • the outer door handle is actuated, only the door handle lever 35 moves.
  • the actuating arm 32 and the unlocking lever 27 remain at rest, so that the blocking element 23 also holds the catch 20 in its closed position.
  • the function of the lever position for the internal actuation corresponds to the central locking function as shown in Figures 8 and 9, so the doors are unlocked from the inside.
  • the function of the child lock is shown in FIGS. 11 and 12.
  • the control cam 47 for the external actuation does not raise the actuating arm 32, so that opening as in the position according to FIG. 7 is possible here.

Abstract

Un système de verrouillage centralisé des portes d'un véhicule automobile comporte toutes les fonctions d'ouverture et de fermeture intervenant en service normal, en cas de défaillance de différentes composantes. Un véhicule ainsi équipé peut, le cas échéant, être ouvert et verrouillé même si les moteurs des serrures de portes ne sont pas en état de fonctionnement (50). Les poignées de portes extérieures (13) peuvent être tirées à fond sans résistance et sans effet lorsque le véhicule est fermé. A cet effet, une came de commande (47) soulève un bras de man÷uvre (32) de telle sorte qu'un levier de poignée de porte (35) puisse être actionné sans saisir le bras de man÷uvre (32).
