EP2669453B1 - Device for opening locks of doors and wings on vehicles - Google Patents

Description

The invention is directed to a device of the type specified in the preamble of claim 1. The device comprises a carrier mounted inside the door. The carrier is a handle, which is operable from the outside of the door.

In addition to the handle in the carrier a tower is provided and accessible from the outside of the door. Normally, the tower serves to receive a lock cylinder, which is used to secure and unlock a lock. Sometimes, for example As to passenger doors, the lock cylinder may be missing. It is then a tower dummy. There is a mitbeweglichen upon actuation of the handle approach, which is used to open the lock. Finally, at least one sensor is provided which becomes effective upon actuation of the handle.

Normally, the lock is in the door and an associated closure member on a fixed part of the body of the vehicle. It would of course also be possible to proceed in the opposite direction and to arrange the closing element on the door or flap and the lock in the fixed body of the vehicle. The invention is directed to both possibilities.

Such a device is from the FR 2 864 981 A known. There is a first sensor which becomes effective upon actuation of the handle in the device. In addition, a second sensor is still provided, which responds when moving the handle in the opposite direction. The lock is opened, regardless of which of the two directions the handle is moved. By this alternative operation, the door can be opened even if the operator has no hand free.

The invention has for its object to facilitate the opening of the lock in a device of the type mentioned in the preamble. This is achieved according to the invention by the solution specified in claim 1

The handle is provided with a lug which is directly or indirectly aligned with a shoulder and engages in the arranged next to the carrier tower. In between, the sensor is arranged, which is designed to be sensitive to force here. Upon actuation of the handle a force or a force change is exerted on the sensor by the interaction between the shoulder and the neck. The sensor then gives a force change signal to an electronic evaluation and control unit. The control unit then opens a lock by means of a motor. So that not any person can open the lock, but only the authorized person, can take place between an owned in the possession of the authorized person identification transmitter and provided in the vehicle or in the handle Identifier communication. Only when the communication is successful, the lock is opened upon actuation of the handle.

As the handle is actuated, the hub, sensor and shoulder move toward each other, compressing the sensor. So an operating force acts on the sensor. For the construction of the device according to the invention can proceed from known devices, which already cause a mechanical opening of the castle. By installing fewer components, namely the approach, the force-sensitive sensor and the shoulder, such a conventional device can be converted into the device according to the invention. Therefore, it is possible to develop a uniform type of door handles which can be used both conventionally and according to the invention. Because of the resulting large quantities, the device according to the invention can be produced inexpensively.

Despite different shape and position, the essential components are provided with the same reference numerals in all embodiments. In not belonging to the invention example of Fig. 1 a portion 11 of a fixed body of the vehicle is shown, on which a door 10 is pivotally mounted. Inside the door is only schematically indicated lock 12, which cooperates with a seated on the body 11 closing piece 13. In the present case, the lock 12 has a rotary latch 14, which sits on a rotatably mounted in the lock shaft 16. The catch has a receptacle which is in the closed position of Fig. 1 the trained here as a bolt closing piece 13 detected.

The door 10 has an outer lining 15. Inside the door, behind the door outer panel 15, a carrier 20 is attached to a door inner frame not shown in detail, which serves for the rotatable mounting 31 of a handle 30. The handle 30 is located on the outside of the door and has at its ends two arms 36, 34 which protrude through two openings in the door outer panel 15 in two openings 23, 24 from the carrier 20 and project. The one arm 36 acts as a bearing end, at which a bearing point 31 between the handle 30 and carrier 20 is located. The other arm 34 is provided with a projection 33 which engages behind a shoulder 21 associated therewith from the carrier 20. Between the shoulder 33 and the shoulder 21 is a sensor 40, which is suitable to sense a force acting on it. The elements 33, 40, 21 touch each other, which is why when actuated in the direction of the arrow 32, the handle 30 performs only a very minimal movement. Right at the beginning of the movement, a signal application of the sensor 40 takes place. For applying force to the sensor 40, the lever action of the handle 30 is utilized.

The force sensing element 40 may be e.g. be a piezoelectric element. By a spring, not shown, the handle 30 is held in its initial position. The piezoelectric element is connected via an electrical line 41 with an evaluation device 42 in connection. The evaluation device is connected by a further line 43 to a control unit 44. If the evaluator 42 detects a force change on the piezoelectric element 40 by means of an actuation 32, the control unit 44 is switched on. The control unit sets an electric motor 45 in motion, which brings the rotary latch 14 out of engagement with the locking pin 13 via the shaft 16. The door 10 is opened by motor.

In the embodiment of Fig. 2 is the handle 30 in a similar manner as in Fig. 1 trained and connected in an analogous manner with the carrier 20. In that regard, the previous description applies. All you have to do is address the differences.

A first difference between Fig. 2 and Fig. 1 is that the approach 33 on the handle 30 is not directly, but indirectly via a gear on the Piezo element 40 acts. This transmission consists in the present case of a transmission lever 28 which is pivotally mounted at 27. The lever 28 is in contact with its one control end 25 with the projection 33, while its opposite working end 26 acts on the force-sensitive sensor 40. The handle 30 is already at rest under a illustrated by a force arrow 35 restoring force. Upon actuation 32 of the handle, the sensor 40 detects a change in the force signals, which are supplied via an electrical line 41 to the aforementioned evaluation and control units.

The second difference is that the approach 33 at Fig. 2 not sitting on the second arm 34. The boom 34 at Fig. 2 has a driving hook 59 which engages behind an initial piece 17 of a linkage. This linkage initial piece 17 to a mechanical connection, not shown, to the lock. In an emergency, when the electrical components of the device fail, a mechanical opening of the lock is possible by means of the handle 30 via the elements 59, 17. For better detection of the handle 30, the carrier 20 and the door outer panel 15 are provided with a recessed grip 18.

A third difference from Fig. 2 across from Fig. 1 is that the pressure-sensitive sensor 40 and its control means 28, 33 are arranged in a tower 50 adjacent to the handle 30. In the present case, the tower 50 has a lock cylinder 51 which is provided with a head piece 52. In the head piece 52 is an access for a mechanical key, which cooperates with the lock cylinder 51. Upon rotation of the lock cylinder by means of the key, a working end 53 of the lock cylinder 51 moves and performs a backup or release of the lock. The head piece 52 is located on the outside of the door outer panel 15 and is connected via a fastening 22 to the carrier 20. The tower 50 could also be a tower dummy without such a lock cylinder 51.

Fig. 3 shows a modification of the in Fig. 2 shown execution. It suffices, therefore, to emphasize the differences here, while in other respects the descriptions too Fig. 1 and 2 be valid.

Also in Fig. 3 is the approach 33 in the upper region of the handle 30 and not in the arm 34. Again, upon actuation 32 of the handle 30 of the pressure-sensitive sensor 40 indirectly, namely pressurized via a transmission member 37. The transmission member consists in the present case of a plunger 37, by a force load 38 in a Fig. 3 apparent starting position. In the present case, the sensor 40 is not force-loaded in the starting position. Upon actuation 32 of the handle 30, the plunger 37 is longitudinally displaced in the direction of the double arrow 39 and exerts a force on the sensor 40, which is forwarded via the electrical line 41 again to the evaluation and control units not shown in detail.

In Fig. 4 schematically a device not according to the invention is shown. In Fig. 4 the handle 30 is provided with two shafts 19, which pass through two longitudinal guides 29 in the carrier 20. Due to springs, a restoring force 35 is exerted on both shafts 19, which are then held pressed against end surfaces 61 which are connected to the carrier 20. When an actuation of the handle 30 in the direction of the arrow 32, the two shafts 19 in the direction of the movement arrows 60 in their guides 29 are moved longitudinally.

At least one of the two shafts 19 is provided with a projection 33, which is again opposed to a shoulder 21 on the carrier 20. In between is the pressure-sensitive sensor 40. Upon actuation 32, the force load determined by the sensor 40 is returned to the evaluation and control unit via the electrical line 41.

In Fig. 5 a device not according to the invention is shown. While in the Fig. 1 to 3 the handle 30 was designed as a one-armed lever, it is in Fig. 5 two-armed trained. The one lever arm is the actual manual actuating point of the handle 30, which is pivotable again in the direction of the arrow 32. On the opposite side of the bearing 31 in the carrier 20 is a second lever arm 62, at the end of the projection 33 is provided. Between the projection 33 and a shoulder 21 of the carrier 20th is again the sensor 40. Without operation 32, the handle 30 of a return spring not shown in one of Fig. 5 apparent starting position held. Then the second lever arm 62 or its projection 33 abuts a stationary stop 54. The stop 54 may be part of the carrier 20.

The Fig. 6a to 6e show a device not according to the invention. There is a first arm 36 on the handle 30, which acts as a bearing end and forms the bearing point 31 for a rotary actuation of the handle 30 with a pin. Here, too, an indirect actuation of a pressure-sensitive sensor 40 takes place via the handle 30, specifically by a deflection lever 46. This deflection lever 46 is pivotably mounted in the carrier 40 by means of bearing journals 47. There are two springs 48, 49, one through the force arrow 66 in FIG Fig. 6d clarified high restoring force exert on the lever 46 and hold it in a defined starting position. The use of two springs 48, 49 serves to better match the spring characteristic. The lever 46 has, as best of Fig. 6c and 6d can be seen, at its one end a receptacle 56, in which a projection 39 engages the end of a handle hook 57. This handle hook 57 is similar to that associated with Fig. 2 already described second arm 34 of the handle 30th

The Fig. 6b shows the top view of a preassembled unit consisting of the carrier 20, the pivotally mounted therein lever 46 and the two return springs 48, 49. The unit of Fig. 6b is in the direction of arrow VIb of Fig. 6a shown. This assembly is first mounted inside the door not shown in detail, behind a door outer panel.

The handle 30 is then subsequently, from the outside of the door, by the already in connection with the first embodiment of Fig. 1 illustrated openings in the carrier 20 and mounted in the door outer panel. This is done by a Einrenkbewegung, according to the pull handles Fig. 6a to 6e is common. In the Einrenkbewegung finds an engagement of the bearing 31 from the bearing end 36 in the in Fig. 6b recognizable opening 23 of the carrier 20 instead. The result is in Fig. 6e to see.

What happens with the handle hook 57 at the opposite end of the handle 30 can best be seen from the Fig. 6c and 6d to explain. As already mentioned, there is at the free end of the reversing lever 46 has a receptacle 56, in which in the Einrenkbewegung the handle hook 57 is introduced with its end-side projection 33. The one wall in the region of the receptacle 56 has an opening 63, in which the handle hook 57 comes to rest after completion of the Einrenkbewegung. In addition to the opening 63 remain wall parts 64, of which at least one is provided with a responsive to force sensor 40. It results in the Fig. 6d recognizable circumstances, to which the following should be noted.

In the case of rest, so if the handle 30 is not yet operated, the two return springs 48, 49 exert the already mentioned spring force 66. It is already possible for a force to act on the sensor 40, which recognizes an evaluation device connected thereto, but does not yet trigger any functions in the vehicle. When the handle 30 according to Fig. 6e is operated manually in the direction of the arrow 32, it is about the seated on the handle hook 57 approach 33 Fig. 6d an actuating force 65 on the sensor 40 exerts. The actuating force 65 is opposite to the spring force 66 in the present case. In a modified construction of this embodiment, the actuating force 65 could be rectified to the spring force 66. In both cases, the force change is detected by the sensor 40 and fed to the evaluation unit 42, which then performs the required functions in the vehicle. Evidently the Fig. 6d is a washer 58 is disposed between the projection 33 and the sensor 40. According to Fig. 6b the carrier is provided with an opening 55 into which a tower and a tower dummy can be mounted.

Despite its movable mounting 31 on the carrier 20 is not only in the last embodiment of Fig. 6a to 6e but also in the preceding embodiments, the handle almost by the mentioned spring load fixedly arranged on the carrier 20. One can speak of a "quasi-stationary handling" at the door. There remain only minimal mobility between the handle 30 and its carrier 20, which are sufficient to produce the detected by the evaluation unit force change on the force-sensitive sensor 40 upon actuation 32. It would also be sufficient to deform elastomeric elements, eg gaskets, upon actuation. The handle 30 then does not need to be rotatably mounted on the carrier 20 or to be longitudinally displaceable. These elastic elements are arranged between a shoulder on the handle 30 and a counter-shoulder on the carrier 20.

The opening of the lock should only be carried out by authorized persons who are in possession of an identification transmitter. In the vehicle is then a corresponding Identifikationsnehmer who communicates during or prior to the operation with the identification transmitter. Code is exchanged monodirectionally or bidirectionally between encoder and slave. This is normally done by remote communication, eg by electromagnetic means. Of course, it is also a close communication between encoder and slave possible, for example by electrical or mechanical contact. If the result of the communication is successful, the sensor 40 and / or its evaluation device 42 are effectively set.
