EP1801324A2 - Locking and unlocking device for a vehicle lock - Google Patents

Abstract

The device has a seat play provided between a handle (20) and a carrier (10), for moving the actuators toward each other. The actuators are evaluated by a sensor (40) and are directed to two different functions in a lock (30). The locking or unlocking of the lock is effected during a desired actuation. The lock is locked or unlocked during a play actuation of the handle in the one direction.

Description

The invention is initially directed to a device of the type specified in the preamble of claim 1. 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 a sensor.

From the DE 196 17 038 C2 is a, device known which has a capacitive sensor, which already responds to the handle when approaching the hand and causes unlocking of the lock. For locking the lock is a separate pressure switch in the handle. This device is expensive to manufacture and susceptible to interference in operation, especially when the capacitive sensitivity is set high. In this case, rain or falling leaves can cause an unwanted capacitive reversal of the lock by the sensor. Although this can be avoided to a certain extent by a low set capacitive sensitivity of the sensor, but this has the disadvantage of relatively long action time for the reversal of the lock during unlocking. That is undesirable.

In this regard, more favorable is a corresponding to the preamble of claim 1 device, which from the WO 2005/038176 A1 is known. Here, a two-part, non-contact sensor is used, which is designed as a Hall sensor and only acts as an unlocking sensor. The one sensor part, namely a permanent magnet, sits on the handle, while the associated electronic part of the Hall sensor is integrated in the handle. To trigger the sensor are the usual, required to open the door operations of the handle. Because the permanent magnet of the Hall sensor sits in the handle, no electrical lines between the handle and the carrier need to be coupled, as required for example in the aforementioned capacitive sensor.

The WO 2005/116376 A1 shows a device in which the handle also has a two-part auxiliary sensor in addition to a main sensor in order to distinguish whether a control of the sensor by a human hand or by error objects. In the case of actuation, both sensors release separate signals, but these are evaluated together. Upon successful evaluation, the lock is transferred in a locking position. The use of a main and an auxiliary sensor requires a lot of space and causes double costs.

The US 4,835,533 A shows a closure with a locking and unlocking system, which is controlled via an identification transmitter in the possession of the authorized person and an identification taker in the vehicle. The identification givers and receivers interact wirelessly and are effectively set when a discriminator in the vehicle detects a match in the communication. There is no sensor here. In the area of the handle an electrical switch with an actuator is arranged, via which a code can be entered.

From the EP 0 218 251 B1 a device with two separate switches is known, which are selectively set by two lying in the same plane, opposing operations of the handle with respect to their rest position effective. When pulling the handle of a switch is actuated, which then unlocks the lock, while pressing the handle of the other switch responds and causes locking of the lock. For unlocking the lock on the one hand and the locking on the other hand are two different Sensors or switches at two different locations required. This is space consuming and causes high production costs.

Such a construction principle is also in the EP 1 111 171 B1 realized. There, the two switches consist of Hall sensors. Again, the handle must be operated by opposing operation from a rest position in the same plane to either address the one Hall sensor or the other.

In the two latter cases, a complex storage of the handle is required, which allows a pulling operation for locking and a pressure actuation for unlocking the lock and must therefore be kept in a neutral rest position without actuation. The means for positioning the handle in the rest position may e.g. Failure of a moving vehicle and unintentionally cause unlocking or locking the lock. In addition, these known devices require a complex storage of the handle on the carrier in order to pivot the handle in Eindrücksinne and pull-out can. These measures are basically not applicable to devices whose handles are connected to their carrier without articulation, so do not need to be pivotally operated to open the lock.

The invention has for its object to develop a reliable device referred to in the preamble of claim 1 species, which is designed to be simpler and more cost-effective. This is inventively achieved by the measures mentioned in claim 1 or claim 3, which have the following special significance.

The invention utilizes and promotes the fact that the seat of the handle on the carrier in addition to the intended target operation to open the lock additionally has a always undesirable in the prior art seat game. Such a seat game, for example, can result from a handle pivotally mounted on the support between the bearing points on the movable handle on the one hand and the stationary bearing mounts on the other. This seat game uses the Invention aware of a respect to the target operation in another direction taking place "game operation" of the handle. 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 desired operation is first used to unlock the lock before it is then used in the same or a subsequent rectified operation to open the lock. The deviating play operation of the handle, conversely, causes a locking or unlocking of the lock.

It is recommended to determine the type of target and game operation by a sensor according to claim 2. In a specific embodiment, the sensor electronics is switched off; the sensor is ineffective. In this case, the authorized person should be in the possession of a mobile identification giver, which shall be referred to below as "ID giver". In the vehicle there is a fixed identification taker, who is to be named in the same way as an ID-taker. The ID slave is connected to an evaluator in the vehicle. If the authorized person moves with her ID transmitter in a defined position with respect to the vehicle or the door, there is a wireless communication between the ID transmitter and the ID receiver. This communication is monitored by the evaluator.

Also in the second solution according to claim 3, the aforementioned ID transmitter and ID receiver are used. 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 from a sensor recognized, who 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 can be used particularly advantageously if, in the solution according to claim 1, the same sensor is used for unlocking and locking the lock, ie basically dispensing 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:

a second embodiment of the first version of the invention, the internal structure of which largely corresponds to FIG. 1, additional components according to claim 2 have been shown 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 with reference to additional components.

All three devices according to FIGS. 1 to 4 have a substantially more consistent construction, which will first be described with reference to the first embodiment of FIGS. 1 and 2. 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. Of the door 15, only the door outer panel 13 is shown in Fig. 1, 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 lines indicated operating position movable, which is marked by an auxiliary line 20.2 in Fig. 1. 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 cooperates in the present case by mechanical means with an only partially fragmented in Fig. 1 illustrated input member 31 of a illustrated only in a block diagram lock 30 of the door 15. 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 expression 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 34 occurs in the first embodiment shown in FIG. 1 and 2 by a special sensor 40. The sensor 40 consists of two sensor parts 41, 42, the non-contact via electrical and / or magnetic fields with each other communicate. 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 symbolically divided into two component groups in FIG. 1. 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 carrier 10 via a pivot bearing 23, the aforementioned desired operation 24 is a pivotal movement of the handle 20. This pivoting movement takes place in FIG. 2 in the pivot plane marked by the auxiliary line 29, which in the present case is perpendicular to FIG the aforementioned door level 14 extends. Each seat 25 of the handle 20 on the carrier 10, including the pivot bearing 23 used in all embodiments, has a illustrated in Fig. 2 seat game 27. The invention uses this seat game 27 in the following manner.

Pressing the handle in the direction of the arrow 28, the handle 20 enters the exaggerated in Fig. 2 dash-dotted play position 20 '. This game position 20 'is also detected by the Hall sensor 40 in the first embodiment of the invention of FIGS. 1 and 2. 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 pivotal movement 29, or transversely thereto, in the direction of the arrow 28 of FIG. 2. Because of this discriminating capability, this Hall sensor 40 "discriminator " to be named. 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.

When the discriminator 49 senses the game operation 28, in the first exemplary embodiment according to FIGS. 1 and 2 of the invention, the already mentioned other group 44 of the electrical components is put into effect, via the lines 37, the control unit 36 and its connection 35 the lock 30 from its unlocked position 34 lead back into 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, as already said, a comparison with FIGS. 1 and 2 modified, third embodiment shown. Because of the analogous structure of the device in Fig. 3, the same reference numerals as in the first embodiment will be used. 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. If the authorized person approaches with his ID transmitter 51 to a minimum distance 18 to the vehicle or to the door 15, a communication illustrated by the arrows 50 in FIG. 3 can 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, 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 illustrates in phantom, the receiver 54. ' for the ID receiver 52 may be located outside the outside door handle in the vehicle as needed, e.g. inside the door 15. Then, a direct connection 55 'between the receiver 54' and the ID receiver 52 is possible, which is also illustrated in phantom in Fig. 3. In other respects, the operation described above applies.

As already mentioned, FIG. 4 shows a third embodiment with a second version of the device according to the invention, which in many respects is similar to the construction of the second embodiment of FIG. It is therefore sufficient in turn, if one enters into Fig. 4 only to the differences from Fig. 3. 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 via the sensor 40. In contrast to the previous embodiment of FIG. 3, the sensor electronics 45 in FIG 4, only the component 44 for locking the lock 30. Thus, the sensor 40 only needs to sense the play operation 28 already described in connection with FIG. 2 and then to continue it via the electrical connections 37 already described to the control unit 36. Then, the locking of the lock 30 marked 33 in FIG. 4 takes place.
