Abstract

The device consists of a lock mounted on each door and actuated by a key. The lock comprises a blocking element (22) pivotally held on the door and a holding element (16) co-operating with the latter and fixed to the bodywork near the door opening. The blocking element is constituted by a spring component for closing the door which engages, in its closed position, in the tenon-shaped blocking element, thanks to a hook-shaped protuberance. The locking element comprises two notched elements which form an angle with respect to their pivot axis; said elements co-operate with elements with corresponding notches which are returned by a spring to their latching position. In order to allow the actuation of said device also using a motor, the lock is provided with a motorized actuating element (50) which pivots towards its closed position to form the door, and which, to open the door moves the locking element against the force of the spring, so that the notched elements and their corresponding elements are mutually released.

Description

Device for locking and unlocking closed doors to the interior of a motor vehicle

State of the art

The invention relates to a device according to the preamble of the main claim. Such a device is already on the market, but in which it is actuated exclusively manually. There are devices for motorized locking and unlocking of closed motor vehicle doors, but there the locking element or an output element of a drive device is pushed back and forth in a straight line (DE-OS 31 20 000, DE-OS 35 16 991), but what is not provided in the device according to the invention.

When locking doors to the passenger compartment of motor vehicles, several operating positions are common and generally known:

A The so-called unlocked position, in which the door can be opened from the outside or opened from the inside without the need for any other mechanism.

B The first closing stage, also called the security or leaning position, in which the almost closed door is not locked correctly, but is nevertheless locked. Opening the door by pulling or pushing is not possible.

C The second closing level or locking position in which the door is properly closed and locked and which cannot be opened by simply pulling or pushing.

These three lock operating positions can also be reached in locks with a structure different from the lock in question via an appropriately adapted motorized actuator.

If the above-mentioned operating position C can be reached at the same time for all doors by the locking movement of a key inserted into a lock, this is referred to as a so-called central locking system.

If all the locks on the doors to the passenger compartment of a motor vehicle are in the operating position belonging to the second locking stage, this is also referred to as the anti-theft position.

In the case of the device according to the application, on the other hand, central locking (operating position D) means an operating state of the entire locking system in which all door locks are in the operating position C, but it is not possible to open the doors from the outside because then the one on the door handle Actuating lever or operating button has no function. However, each door can be opened easily from the passenger compartment if the so-called locking button on the door or a corresponding lever is operated beforehand. Finally, the device according to the present application for industrial property rights also has an operating position in which the doors can only be unlocked by means of an electric motor. This position cannot be changed even if, for example, a window pane was broken in and then pulled on the locking button. Since this operating position can only be entered from the outside via the door key to a so-called central electronics unit and from there onto a servomotor assigned to the actuating element, and the change thereof - with the exception of an emergency unlocking function, which is still to be explained - can only be reached via the servomotor, this operating position is to be referred to here as the anti-theft position (operating position E).

Advantages of the invention

In contrast, the locking and unlocking device according to the invention with the characterizing features of the main claim has the advantage that with it also a pivotable locking element and additionally a locking, also pivoting locking element can be moved by motor according to the requirements.

Advantageous further developments and improvements of the device specified in the main claim are possible through the measures listed in the subclaims.

Description of the embodiment

A locking and unlocking device for the doors to the interior of a motor vehicle includes, according to the exemplary embodiment, four door locks 10, of which one, namely the door lock arranged on the driver's door 11, has been drawn objectively. The Driver door 11 is indicated over a short partial area and provided with a door handle 12. The door lock 10 has a support plate 14 on which the further parts belonging to the lock are arranged. The door lock 10 also includes a so-called locking pin 16, which is arranged in the area of the door opening on the frame of the door and is firmly connected to it. The arrangement of the locking pin 16 is such that when the door is closed it reaches an open-ended channel 18 of the support plate 14 which narrows in its extent. At the end of the channel 18 there is an elastic buffer 20 which is acted upon and deformed by the locking pin 16 when the door is closed. On the support plate 14, a locking element 22 is pivotally mounted. The locking element 22 is approximately plate-shaped and has an open-edge recess 24, so that a hook-like arm 26 results (Fig. 2). Relative to the pivot axis 27 of the locking element 22, the edge-open recess 24 is approximately opposite a lever 28. The locking element 22 is spring-loaded in a clockwise direction via a prestressed leg spring 30 and, in the operating position shown, is placed against a stop 31, from which the locking element 22 can be pivoted counterclockwise and against the force of the leg spring 30.

Furthermore, the lock 10 has a locking element 32, which is also pivotally mounted on the support plate 14. The locking element 32 has a first swivel arm 34, on which counter-latching means 36 are formed on a correspondingly aligned edge, which can work together with edges 38 and 40 of the blocking element 22 designed as latching means during operation of the device. (See Figures 2 and 3). Furthermore, the locking element 32 has a second swivel arm 42, which is cranked out of the plane of the drawing in relation to the first swivel arm 34 and extends further in a plane which is closer to the viewer than the plane in which the locking element 22 is located. The free end of the second swivel arm 42 extends into the area of the lever 28 of the locking element 22. A tension spring 46 anchored to the support plate 14 engages on a tab 44 of the locking element 22 and tries to pivot the locking element 32 clockwise. In the operating position shown in Figure 2, the tab 44 is supported on a buffer 48 of the support plate 14, so that the operating position of the locking element 32 shown here is initially maintained. Finally, an actuating element 50 is mounted in the support plate 14 (FIG. 2), which is designed as a two-armed lever and is fixedly connected to a shaft 52 which is connected via an electric lock or drive motor 54 (FIG. 1) in the direction of the arrow 53 can be driven. The drive connection between the shaft 52 and the drive motor 54 has been indicated by a line 55 shown in FIG. 1. It is pointed out that the actuating element 50 in FIGS. 2 to 7 is drawn in a greatly simplified manner for the sake of a better overview. In the area of the free ends of the lever arms 56 and 58, two bolts are anchored, of which one bolt 60 first stretches towards the viewer, while the other bolt 62 protrudes from the arm 58 toward the support plate 14. The lever arms 56 and 58 are arranged such that the pivoting plane of the arms 56, 58 is located between the lever 28 of the locking element 22 and the second pivot arm 42 of the locking element 32. The flight circles of the two bolts 60 and 62 are dimensioned such that one bolt 60 cooperates with the second swivel arm 42 while the bolt 62 is connected to the lever 28.

Finally, an elongated slide 64 is slidably guided in tab 66 bent out of the support plate 14 on the support plate. In its central region, the slide 64 has a cam 68 which cooperates with an oblique contact surface 70 which is formed on the second swivel arm 42 of the locking element 32. Furthermore, the slide 64 is held in a first operating position by means of a prestressed tension spring 72, from which the slide 64 can be raised against the force of the spring 72. This can For example, by a locking button 73, which has been indicated in Figure 1. A connection line 75 has been drawn in there to demonstrate the connection between the locking button 72 and the slider 64. The locking button 73 is known to be located inside the vehicle in the lower region of the window frame. However, it can also be replaced, for example, by a folding lever or the like provided in the region of the inner door handle. In order to understand the present invention, it is in any case important to know that the slide 64 can only be lifted out of its operating position shown manually, with the aid of the locking button 73 and from inside the vehicle.

In the exemplary embodiment shown, the door handle 12 is designed as a so-called lever handle, which can be folded out of the door 11 acting like a one-armed lever. The door handle 12 works together with a component 74 which is operatively connected to the slide 64 via a line designated 76 in FIG. 1. The line 76 is intended to demonstrate that when the door handle 12 is actuated in the direction of the arrow 77 in FIG. 2, the slide 64 can be lifted out of the operating position shown in FIG. 2 against the force of the spring 72. When the door handle 12 returns to its starting position, the slide 64 is pulled back into its operating position shown in FIG. 2 by the force of the spring 72. Finally, the device according to the invention is provided with a locking unit 78 which has a servomotor 80 which is able to pivot a blocking element 84 via a spur gear reduction gear 82.

When considering the blocking assembly 78, it should be noted that it has been drawn rotated by 90 degrees. A key opening 86 (FIG. 2) arranged in the blocking element 84 must face the wall of the door 11. The components 74, the blocking element 84 and the slide 64 are each assigned sensors 88, 90 and 92, by means of which the respective operating position of these components are communicated to central control electronics 100 via control lines 94, 96 and 98. Further sensors of this type are assigned to the actuating element 50 and the blocking element 22. The control lines of these sensors, which are not visible in the drawing, are designated 102 and 104. Finally, control lines 106 and 108 lead from the drive or lock motor 54 and the servomotor 80 to the control electronics 100. An output shaft 110 of the lock motor 54 is operatively connected to the shaft 52 of the crank-like actuating element 50 (line 55). All control lines 94, 96, 98, 102, 104, 106 and 108 are shown as cable harnesses for the other door locks 10 indicated in FIG. 1 and have been given the reference number 112.

In operation, the locking and unlocking device described works as follows:

Starting from the operating position A shown in Figure 2, the door can be closed manually. When the door closes, the locking pin 16 reaches the recess 24 of the locking element 22 which is open at the edge and pivots the latter against the force of the leg spring 30 into the operating position B shown in FIG. 3. During this pivoting movement of the locking element 22, the locking element 22 becomes locked locking element 32 temporarily pivoted against the force of the tension spring 46 until the counter-locking means 36 of the first pivot arm 34 cooperate with the locking means 38 of the locking element 22. The resulting operating position B is shown in Figure 3. By further pressing the door 11, the locking element 22 is pivoted further against the force of the leg spring 30 until it reaches the operating position C shown in FIG. The locking element 32 is temporarily deflected against the force of the tension spring 46 until the counter-locking means 36 of the first swivel arm 34 cooperate with the locking means 40 of the hook-like arm 26 of the locking element 22. In this operating position the door is close and the locking element 22 secured by the locking element 32. The operating position of the blocking element 22 thus achieved is communicated to the control electronics 100, which causes the actuating element 50 to be pivoted by 180 degrees in the direction of the arrow 53 (FIG. 3). This already occurs during the closing of the door, as can be seen from the position of the actuating element 50 from FIG. 3. If, however, the door is only brought into the operating position B and the actuating element 50 then executes the movement just described, the lever 28 of the locking element 22 is carried along by the bolt 62, so that the door 11 is completely closed by the lock motor 54, because the locking element 22 engages behind the locking pin 16 with its hook-shaped arm 26 and pulls into the operating position C during the swiveling movement. It is therefore clear that the door 11 can be closed both manually and by motor. The driver's door in particular can also be opened both manually and by motor. This is effected from the outside by actuating the door handle 12, because as a result the mechanical connection from the component 74 via the connecting line 76 to the slide 64 is raised against the force of the spring 72. The cam 68 presses the second swivel arm 42 of the locking element 32 counter-clockwise while running against the inclined surface 70, so that the counter-latching means 36 disengage from the latching means 40. The biasing force of the leg spring 30 then pivots the locking element 22 into its operating position shown in FIG. 2, so that the locking pin 16 is released. The buffer 20 deformed when the door is closed pushes the door slightly out of its closed position so that it can be pushed open or pulled open both from the inside and outside without difficulty.

The sensors assigned to the blocking element 22 inform the control electronics 100 via the control line 102 of its current operating position and the lock motor 54 brings the actuating element 50 back into the operating position shown in FIG. When opening the Door from the inside is also raised by pulling the locking button 73 or by actuating a corresponding lever via the connection indicated by the line 75 (FIG. 1), so that the procedure described above is carried out. If the door is now to be opened from the inside, the lock motor 54 is activated, which swivels the actuating element 50 by 180 degrees. The shoulder 60 forming a shoulder strikes a counter shoulder 43 formed on the second swivel arm 42, so that the locking element 32 is swiveled counterclockwise by a motor. Here too, the counter-locking shoulder 36 releases the locking shoulder 40 of the hook-like arm 26 of the locking element 22, so that the latter reaches its operating position A shown in FIG. 4 into the operating position A shown in FIG.

In certain situations it is desirable to secure the doors of a motor vehicle in such a way that they cannot be opened from the outside but without difficulty from the inside. For this purpose, the device to be described here has the blocking unit 78. If the doors are to be secured from the inside, the servomotor 80 is actuated, which swivels the blocking element 84 from its operating position shown in FIG. 2 by approximately 90 degrees and transfers it to the operating position shown in FIG. The process is communicated to the central control electronics 100 via the control line 96. From Figure 6 it can be seen that the door handle 12 is now blocked because the blocking element 84 prevents the component 74 from moving. To simplify the device, it is sufficient if only a single vehicle door, for example the driver's door or its lock, has a locking unit 78. The other door locks can be designed as shown in FIG. 7. Instead of the locking unit 78, the door lock only has an electronic switch 120 which can be operated using a door key. The electronic switch 120 has a movable component which is connected to a carrier 122 which can be rotated with the key. It acts with a magnetic component 124 of the electronic switch 120 together. Switch 120 is undefined. When the carrier 120 is rotated, the signal to the central electronics 100 changes. This then causes the lock motor 54 of each door to be activated such that all the actuating elements 50 are moved from their current operating position to the other operating position . If the actuating element 50 is in its operating position shown in FIG. 2, it is brought into the operating position shown in FIG. 4 and vice versa.

Furthermore, the door on the locking element 22 is automatically closed and closed when this door is in the operating position B shown in FIG. 3. This is effected by the sensor, which detects that the locking element 22 is in its so-called leaning position shown in FIG. 3. This applies to all doors.

Finally, an anti-theft position (operating position E) shown in FIGS. 6 and 7 can be set. In this position, the locking element 22 is blocked by the bolt 62 in its operating position shown in FIG. 4. This means that it cannot snap back into the operating position shown in FIG. 2 under the pretension of the leg spring 30 when the locking element 32 releases the locking element 22. In FIGS. 6 and 7, the anti-theft locking position designated initially as operating position E is reached. As far as the lock has been described so far, this operating position E can only be canceled by actuating the lock motor 54, because only this is able to move the actuating element 50 into a position in which it releases the locking element 22 again.

However, in order to enable problem-free, manual opening of the door even if the electrical system of the motor vehicle fails, the actuating element 50 is constructed as shown in FIGS. 8 to 10. In Figures 11 and 12, the driver's door Side door lock 10 shown with this special actuating element 150, the locks being in the operating positions already described in both cases. FIG. 11 shows an operating position as shown in FIG. 4. FIG. 12, on the other hand, shows a lock position, as has already been explained with reference to FIG. 6. This special actuating element 150 is constructed according to FIGS. 8 to 10 from two sub-elements 152 and 154. One sub-element 152 is connected in a rotationally fixed manner to the shaft 52. The other sub-element 154, on the other hand, can be rotated with respect to the shaft 52 because it is guided on a stepped sleeve 156 which is connected to the shaft 52 in a rotationally fixed manner. One sub-element 152 has a bolt 160, while the other sub-element 154 is provided with a pin 162. Both the bolt 160 and the pin 162 correspond to the components 60 and 62, which have been described with reference to the figures described above. Furthermore, the sub-element 154 has a segment-like recess 164 which is open at the edge and into which an entrainment extension 166 of the bolt 160 projects. One wall 168 of the recess 164 serves as a driver for the entrainment extension 166 of the bolt 160. Finally, the other sub-element 154 also has a hook-shaped extension 170, which can interact with a counter-hook 171 of the slide 64 if the two-part actuating element 150 according to FIGS Figures 8 to 10 is rotated counterclockwise (Figure 12). During normal operation, the entrainment extension 166 of the bolt 160 is held against the entraining surface 168 of the recess 164 open at the edge by a prestressed tension spring 172. For this purpose, the tension spring 172 is suspended at one end on one component 152 on a hook 174, while its other end is fixed on the other sub-element 154. Against the biasing force of the tension spring 172, the other sub-element 154 can be rotated relative to the one sub-element 152 by a certain angle 06, which is determined by the arc length of the recess 164 open at the edge and the diameter of the driving extension 166. The bolt 160 extends from the one element 152 so that it is connected to the lever 28 of the locking elements 22 can work together. The pin 162, however, corresponds essentially to the pin 62 according to the embodiment shown in Figure 2 and works with the second pivot arm 42 of the locking element 32. Relative to the axis of rotation of the shaft 52, the pin 162 and the bolt 160 are diametrically opposite one another when the tension spring 172 holds the driving extension 166 of the bolt 160 against the driving surface 168 of the open-edge recess 162 of the other partial element 154. Furthermore, the other sub-element 154 has a hook-like projection 170, which is able to cooperate with the counter-hook 171 of the slider 64 when the actuating element 150 is rotated counterclockwise. If the lock 10 is now in the operating position shown in FIG. 12, in which the operating position E is shown, the pin 162 blocks the lever 28 of the locking element 22. If the electrical system of the motor vehicle fails, however, the vehicle can act as can be opened manually without difficulty:

Via the door lock, the blocking element can be turned from its blocking position according to FIG. 12 into an operating position, as shown for example in FIGS. 1 to 4, with the aid of the key or another auxiliary means. This is possible because the reduction gear 82 is designed as a spur gear. Then the door handle can be operated manually so that the slide 64 is raised against the force of the spring 72 via the connection 76. The cam 68 of the slide 64 lifts the securing element 32 out of its detent position relative to the locking element 22 and at the same time the two hook configurations 171 and 170 of the slide 64 and the other partial element 154 work together in such a way that the other partial element 154 is in the clock ¬ is pivoted by an amount which is made possible by the arc length or the angle <λ of the segment-like recess 164 which is open at the edge. With respect to the diameter of the entraining extension 166, this radian measure is dimensioned such that the pin 162 releases the lever 28 of the locking element 22. Then the locking element 22 jumps in under the biasing force of the leg spring 30 its position shown in Figure 2, in which the door is open. All of these special designs enable the door or lock positions A, B, C, D and E to be reached by motor in a door lock of the type described here. Furthermore, it remains completely free to manually close the doors from the outside and from the inside. Operating position D also enables the door to be opened easily from the inside. Finally, the operating position E creates a possibility in which the door can be opened neither by motor nor manually without a vehicle key.

A particularly simple embodiment of the device according to the invention is explained below with reference to FIGS. 13 to 21. In this embodiment, the blocking assembly 78, together with the associated components 80, 84, 90, 96, 108 and 74, is omitted in accordance with the embodiment already described. Since all other components of this embodiment - with the exception of the actuating element 150 and the slide 64 - correspond to the embodiment described above, the designations and reference numbers used there are retained in the following. However, the locking element 32 has a slight deviation insofar as its second swivel arm 42 is shortened, so that the counter shoulder 43 is omitted. This avoids possible, unintentional opening of the door 11 in certain operating situations.

The actuating element 250 (FIGS. 13 to 21) has on its one partial element 252 a deflection cam 255, which cooperates with a slide 264, which replaces the slide 64 of the embodiment described. The slider 264 is U-shaped in cross section in the area adjacent to the actuating element 250. The two U-legs encompass a second slide 266, which is longitudinally displaceable independently of the first slide 264. The one, in the figures 13 to 20 lower leg of the slider 264 has a hook projection 270 which corresponds to the hook formation 171 of the other embodiment. The upper U-leg 275 has a cam 268 which functions as the cam 68 of the first takes over and which thus cooperates with the swivel arm 42 of the locking element 32 when the slide 264 is moved against the force of the prestressed spring 72. For this purpose, for example the locking button 73 (FIG. 1) can be actuated at the end of the slide 264 facing away from the spring 72 in an elongated hole 274, in which the one end of a Bowden cable 275 is hung, which is operated by a handle located in the passenger compartment of the motor vehicle is. The other, second slide 266 is likewise loaded in its longitudinal direction via a prestressed tension spring 172. Its end facing away from the spring 172 is operatively connected via a linkage 268 to a crank 269 which is fastened to the locking cylinder 282 of a locking device 284 belonging to the door 11 which can be rotated by a key 280. Finally, the second slide 266 is provided with a hook projection 286. The two hooks 270 and 286 of the two sliders 264 and 266 are located in mutually adjacent planes which extend within the plane of the sub-element 254 with its hook-shaped extension 170. The Auslenk¬ cam 255 of the sub-element 252 is arranged so that it cooperates with the leg 275 of the slide 264. The leg 275 is equipped in this area with a plastic slide 276 (FIG. 21), so that no undesirable operating noises occur. Furthermore, the arrangement of the already described pin 160 with respect to the deflection cam 255 is such that an operating position is obtained even when the slide 264 is deflected, in which the pin 160 blocks the locking element 22 in the operating position shown in FIG. 18 because it against the counter shoulder formed on the second swivel arm 42 of the locking element 22, formed by the lever 28. The locking element 32 is provided with an actuating lever 133, on which the handle 12 (FIG. 1) attached to the outside of the door 11 engages via a linkage 134. When the handle 12 is actuated, the locking element 32 is pivoted counterclockwise via the linkage 134 and the actuating lever 133, so that the locking and counter-locking means 38, 40, 36 of locking element 32 and locking element 22 disengage. The operation of the embodiment according to Figures 13 to 21 is explained below with reference to the drawing. The lock actuation from the operating position according to FIGS. 13 and 14 (open or unlocked position A) into the positions according to FIG. 15 (leaning position B, which also represents the lock during the closing process) and FIG. 16 (locked position C) corresponds entirely to that already described operation according to Figures 3 and 4. This also applies to the motorized reaching of the operating positions according to Figures 17 (central locking D) and 18 (anti-theft device E).

The removal of the position D from the passenger compartment of the motor vehicle takes place here as follows: When the handle located in the passenger compartment (inner handle or unlocking button) is actuated, the Bowden cable 275 pulls the slide 264 upwards, its hook 270 with the hook formation 170 of the other sub-element 154 of the actuating element 250 comes into engagement, so that the latter is rotated clockwise and the bolt 160 releases the lever 28 of the locking element 22. At the same time, the cam 268 of the slider 264 runs against the inclined surface 70 of the second swivel arm 42 of the locking element 32 and pivots this in the counterclockwise direction, so that the locking element 32 releases the locking element 22 because the locking and counter-locking means 40 and 36 except Intervention. This means that the central locking system on the relevant door is released from the inside.

The effect of the so-called anti-theft device (E) comes about in this embodiment in that, as shown in FIG. 18, the bolt 264 has been removed so far from the shaft 52 of the actuating element 250 by the deflecting cam 255 of the one partial element 252 that the Hook 270 of the bolt 264 is outside the flight circle of the hook formation 170 of the other sub-element 154. The deflection cam 255 has pressed the bolt 264 away against the force of the tension spring 72. A defined position of the bolt 264 is achieved by a guide pin 290 fixed to the frame reached, which engages in a longitudinal slot 292 of the bolt 264. In this operating position, the door in question can be opened neither from the inside nor from the outside, because actuation of the outer handle or the outside handle pivots the locking element 32 counterclockwise, so that the locking element 22 is released by the locking element 32, but the locking element 22 remains blocked the bolt 160 of the other sub-element 254. When the inner handle is actuated, the Bowden cable 275 pulls the bolt 264 upward, but its hook 270 and the hook formation 170 do not engage with one another, so that the blocking of the locking element 22 cannot be released either. The locking pin 16 serving as a holding element thus remains engaged by the blocking element 22.
