EP1801324B1 - Locking and unlocking device for a vehicle lock - Google Patents

Description

The invention is directed to a lock with a device for unlocking and locking this lock in a vehicle. The lock is normally located in the door of the vehicle and cooperates with a stationary part on a stationary body part. To operate the lock is an accessible from the outside of the door handle, which sits on a carrier mounted inside the door. The operation of the handle is monitored by at least one sensor.

Such a lock is from the WO 2005/116376 A1 known. In this known device, a two-part auxiliary sensor is arranged in the contact region of the handle except a main sensor, which consists of a permanent magnet and Hall element. One part of the auxiliary sensor is seated on the movable handle, while the other part is arranged on the stationary support. There is a seated game between the handle and the carrier. Thus, a vertical and / or horizontal movement of the handle against the carrier is possible. The main and auxiliary sensors emit separate signals. Only a successful evaluation of both signals transfers the lock into a locking position, where the operation of the handle for the lock is ineffective. For reversing the lock in an unlocked position, where the operation of the handle for the lock is effective, you need a third sensor. These sensors can not distinguish each other directionally different operations of the handle. This is space and costly.

The invention has for its object to develop a reliable and cost-saving lock with a device for unlocking and locking the lock, where the unlocking and locking of the castle are effected by different movements of the handling.

The invention uses the seat of the handle on the carrier except for the intended target operation to open the lock also in terms of his seat game. Such a seat game can be e.g. result from a pivotally mounted on the carrier handle between the bearing points on the movable handle on the one hand and the stationary bearing receptacles on the other hand. This seat game uses the invention specifically for a "play operation" of the handle taking place in a different direction in relation to the desired actuation. That is enough. However, it would be possible to define and use everything as a "game operation", which takes place in a direction deviating from the desired operation.

In the first solution of the invention specified in claim 1, the sensor is designed as a discriminator, the operations of the handle differs in different directions and leads to two different functions in the castle. A set operation not only causes the opening of the lock, but also serves for unlocking. In a game operation of the handle, however, which takes place in the opposite direction, the lock is locked.

According to claim 2 is in the possession of an authorized person an identification transmitter, which will be referred to briefly below with ID donors. Upon approach of the authorized person to the castle wireless communication takes place with a fixed identification takers, which should be called ID-taker. This is located in the vehicle and is connected to an evaluator in the vehicle. Normally, if the ID transmitter is outside the communication range of the ID slave, the sensor electronics are disabled. The evaluator monitors the communication between the ID transmitter and the ID receiver. Normally, if the ID transmitter is outside a communication range from the ID receiver, the sensor electronics are deactivated. Within the communication range, however, the sensor electronics are set to effective. In this case - starting from a locked lock - in an initial phase of the set operation, the handle unlocks the lock and in the subsequent phase of this set operation, the lock is opened, allowing the door or flap of the vehicle to open.

The aforementioned ID transmitter and ID receiver are also used in a second solution according to claim 3. In this case, the ID transmitter or the ID receiver are constantly in use and ready for communication. When approaching the ID transmitter to the ID receiver, therefore, a start of the communication is not necessary, but results in successful communication immediately unlocking the lock. For this reason, takes place at the desired operation of the handle immediately opening the lock; a previous unlocking is no longer necessary in this case. The locking, however, takes place in the manner already described by utilizing the game operation of the handle. This is detected by a sensor, which then locks the lock. In this case, a sensor or electronics need not be arranged in the region of the handle of the outside door handle. The invention according to claim 1 uses for unlocking and locking the lock the same sensor, and thus basically dispenses with two different sensors. Namely, the invention has recognized that such a sensor can function as a discriminator capable of discriminating different operating directions of the handle. In a desired operation of the handle of the discriminator will cause the unlocking of the lock, while the game operation according to the invention causes the handle the same discriminator to cause the locking of the lock.

Further measures and advantages of the invention will become apparent from the dependent claims, the following description and the drawings. In the drawings, the invention is shown only schematically in three embodiments. Show it:

Fig. 3

a second embodiment of the first version of the invention, whose internal structure largely the Fig. 1 corresponds additional components according to claim 2 have been drawn in addition and

4,

also with reference to the first embodiment of Fig. 1 , A second version of the invention, which illustrates the subject matter of claim 3 on the basis of additional components.

All three devices according to Fig. 1 to 4 have a substantially more consistent structure, first with reference to the first embodiment of Fig. 1 and 2 should be described. Each of the three devices comprises a carrier 10, which is fixed in the interior 11 of a door 15 of a vehicle in a known manner. From the door 15 is in Fig. 1 only the door outer panel 13 is shown, which determines a clarified by the dashed line 14 door level 14.

On the display side 17 of the door outer panel 13 protrudes a handle 20 in the door outer area 12 out. The handle 20 is seated in a manner known per se on the carrier 10. In the present case, the seat 25 consists of a pivot bearing 23 between the one end 21 of the handle 20 and the carrier 10. It is a "bearing end 21" of the handle 20th As a result, the handle 20 in the sense of the pivot arrow 24 of Fig. 1 between its solid lined and illustrated by the auxiliary line 20.1 rest position in a dash-dotted line indicated operating position movable by an auxiliary line 20.2 in Fig. 1 is marked. A return spring not shown in detail is anxious to hold the handle 20 in its rest position 20.1. The handle 20 is thus pivoted away from the door plane 14 at the intended operation in the sense of the pivot arrow 24. This pivotal movement 24 is intended to be referred to below as "nominal operation" of the handle.

Opposite the above-described bearing end 21, the handle 20 has a working end 22, which in the present case by mechanical means with only a fragmentary in Fig. 1 clarified input member 31 of a illustrated only in a block diagram lock 30 of the door 15 cooperates. In the rest position 20.1 of the handle, the lock 30 is closed, but can alternatively be converted into a locking position 33 or an unlocking position 34, which is expressed by a complementary portion of the block diagram to express comes. In the locking position 33, a set operation 24 of the handle 20 is ineffective; the lock 30 remains closed. The door can not be opened. The opening of the door 15 is possible only in the unlocked position 34 of the lock 30.

The working end 22 of the handle 20 has a hook which engages behind the input member 31 from the lock 30. If the handle 20 is pivoted into its actuating position 20.2, the hook 26 arrives in its dash-dot clarified position in the sense of the movement arrow 32, whereby the lock 30 is opened when it is, as I said, in its unlocked position 34. Then, the door 15 can be moved over the handle 20 relative to the stationary body part.

The reversal of the lock 30 between the aforementioned locking position 33 and unlocking position 34 is done in accordance with the first embodiment Fig. 1 and 2 by a special sensor 40. The sensor 40 consists of two sensor parts 41, 42 which communicate with each other without contact via electrical and / or magnetic fields. In the present case, a Hall sensor 40 is used, whose one sensor part 41 consists of a permanent magnet which is integrated in the handle 20 and is therefore moved in its desired operation 24 relative to the other stationary sensor part 42 of the Hall sensor 40. This stationary sensor part 42 is indirectly, namely via an electronics housing 45, detachable component of the carrier 10. If the vehicle is to be equipped with the sensor electronics 45, the electronics housing is subsequently attached to the back 16 of the carrier.

The sensor electronics 45 comprises a main housing 46 and a housing extension 47, which receives the stationary sensor part 42 of the Hall sensor 40 and connects it to electrical components 43, 44 in the main housing 46. The electrical components 43, 44 are in Fig. 1 symbolically divided into two component groups. The one component group 43 responds to the set operation 24 of the handle. Then, the lock 30 is reversed electrically and / or mechanically via the schematically indicated connection 35; it is transferred from its locking position 33 in its unlocked position 34. This connection 35 goes from one electrical control unit 36, which is connected via an electrical cable 37 and a plug 38 with a corresponding electrical coupling 48 on the electronics housing 45.

In the present case, where the handle 20 is seated on the support 10 via a pivot bearing 23, the aforementioned desired operation 24 is a pivoting movement of the handle 20. This pivoting movement takes place in Fig. 2 in the marked by the auxiliary line 29 pivoting plane, which in the present case is perpendicular to the door level 14 mentioned above. Each seat 25 of the handle 20 on the carrier 10, including the pivot bearing 23 used in all embodiments, has a in Fig. 2 illustrated seat game 27. The invention utilizes this seat game 27 in the following manner.

If you press the handle in the direction of the arrow 28, the handle 20 enters the in Fig. 2 exaggerated dash-dotted game position 20 '. This game position 20 'is in the first embodiment of the invention of Fig. 1 and 2 also detected by the Hall sensor 40. Namely, the Hall sensor 40 can discriminate whether the two sensor parts 41, 42 move toward each other in a predetermined operation 24 in the aforesaid pivoting movement 29, or transversely thereto, in the direction of the arrow 28 of FIG Fig. 2 , Because of this discrimination, this Hall sensor 40 can be called a "discriminator". In addition, the movement 28 of the handle from its normal position 20 in its playing position 20 'hereinafter referred to as "game operation". This game operation 28 takes place substantially parallel to the door plane 14. The discriminator 49 could also consist of two Hall sensors, or have a double stationary sensor part 42 in the housing arm 47 in order to distinguish the aforementioned operations 24, 28 can.

If the discriminator 49 senses the game operation 28, then in the first embodiment according to Fig. 1 and 2 the invention, the aforementioned other group 44 of the electrical components effectively set, which lead back through the lines 37, the controller 36 and its connection 35, the lock 30 from its unlocked position 34 in its locking position 33. As it can be seen, the reversal of the lock 30 between its two positions 33, 34 in both control directions by utilization or non-utilization of the seat game 27 of the handle 20 is possible. The unlocking takes place in the initial phase of the required anyway to open the door pivoting movement 24 of the handle 20. For locking the lock, however, as I said, the seat game 27 of the handle used in their storage 23. For the latter, therefore, apart from the discriminator 49, no special measures for the device according to the invention need to be made.

The device according to the invention is also applicable to handles 20, which do not have a hinge connection 23 with the carrier 10, but, apart from an analog seat game, sit substantially immovably on the carrier. Also, such immovable handles of course have a game in their seat 25, which can be used in an analogous manner for the described game operation 28. In this case, one uses in different directions operations, all based on the seat game 27, on the one hand for the desired operation 24 and on the other hand for the game operation 28th

In Fig. 3 is, as already said, one opposite Fig. 1 and 2 modified, second embodiment illustrated. Because of the analogous structure of the device in Fig. 3 the same reference numerals should be used as in the first embodiment. In that regard, the previous description applies. All you have to do is address the differences.

According to Fig. 3 There is first an ID transmitter 51, which is in the possession of an authorized person not shown in detail. Stationary in the vehicle, the ID transmitter 51 is associated with an ID receiver 52, which in turn is connected to an evaluator 53. Approaches the authorized person with its ID transmitter 51 to a minimum distance 18 to the vehicle or to the door 15, so one by the arrows 50 in Fig. 3 illustrated communication take place. It is understood that this communication 50 can be mono- or bidirectional and that corresponding transmitting and receiving means are provided in the ID transmitter 51 and in the vehicle or in the outside door handle. In the embodiment of Fig. 3 is located, for example Such a receiver 54 of the ID receiver 52 in a further component 19 of the outside door handle, namely a cover, which is arranged next to the handle 20.

The receiver 54 is connected via lines 39, which may occasionally be guided by the main housing 46 of the sensor electronics 45, and a first output line 55 of the main housing 46 with the ID-receiver 52. The result of the communication 50 is monitored by the evaluator 53. In this second embodiment, the receiver 54 is a constant query, which is ready for communication 50. As a result, the communication 50 takes place immediately when the ID transmitter 51 has reached the prescribed minimum distance 18. If the evaluator 53 detects a match in the communication 50, it switches the sensor electronics 45 to focus. Then, the discriminator 49 acting in a double sense sensor 40 is turned on and reacts in the already described in connection with the manner described in the first embodiment, both a desired operation 24 and a game operation 28th

As Fig. 3 illustrated by the dot-dash line, the receiver 54 'for the ID receiver 52 could if necessary be located outside the outside door handle in the vehicle, eg inside the door 15. Then a direct connection 55' between the receiver 54 'and the ID receiver 52 is possible, in the Fig. 3 also dash-dotted lines is illustrated. In other respects, the operation described above applies.

As already mentioned, the shows Fig. 4 a third embodiment with a second version of the device according to the invention, which in many ways the structure of the second embodiment of Fig. 3 like. It is sufficient, therefore, once again in Fig. 4 only to the differences Fig. 3 received. In other respects, the previous description applies.

Also in this third embodiment, there is a constant query of the ID transmitter 51 by the ID receiver 52 in the manner described. If the minimum distance 18 is reached, the communication is 50 if the communication matches The controller 36 then switches the lock 30 directly into its unlocked position 34, without the use of the sensor 40. Then, by the set operation 24 of the handle 20, the door 15 in the usual manner be opened.

The lock 33 of the lock 30 is then again in the usual manner, as seen in isolation, has been explained in the first and second embodiments, namely the sensor 40. In contrast to the previous embodiment of Fig. 3 includes the sensor electronics 45 in Fig. 4 only the component 44 for locking the lock 30. So the sensor 40 only needs in connection with Fig. 2 already described game operation to sense 28 and then continue on the already described electrical connections 37 to the controller 36. Then the in Fig. 4 33 with the locking of the lock 30.
