Definitions
- Motor vehicle lock in particular motor vehicle door lock
- the invention relates to a motor vehicle lock, in particular a motor vehicle door lock, with a locking mechanism consisting essentially of a rotary latch and a pawl, also with at least one electric motor drive and a control unit, and with an at least two-part housing with a wet room housing part and a dry room housing part, the drive and the Control unit in the dry room housing part and the locking mechanism in the wet room housing part are arranged.
- Motor vehicle locks and in particular motor vehicle door locks are exposed to very different environmental conditions, depending on the climatic areas in which an associated motor vehicle is located. This applies in general to motor vehicle locks, including those that are not necessarily arranged on and in a motor vehicle door.
- the motor vehicle lock can be a lock on a seat back, a glove compartment, a tailgate, etc.
- motor vehicle door locks ie motor vehicle locks which are fitted in or on motor vehicle doors and ensure that they are closed.
- motor vehicle door is to be interpreted broadly, because this expressly includes not only motor vehicle side doors, but also motor vehicle front hoods, motor vehicle tailgates, motor vehicle sliding doors, etc.
- the different environmental conditions not only include different temperatures far below to far above the freezing point (from -50 °C to +80 °C), but also and especially dust and moisture as well as rain.
- the ratchet interacts from im Essential rotary latch and pawl usually with a locking bolt on the motor vehicle. This presupposes that the locking bolt can move into an inlet mouth of the housing, which is therefore open and consequently exposed to the different environmental conditions.
- wet room in contrast to the dry room, for example inside a motor vehicle door, in which safety devices such as side airbags, window regulators, loudspeakers, etc. are located.
- the dry room is particularly splash-proof compared to the wet room. Accordingly, there are already a variety of approaches in the prior art to implement a perfect, splash-proof and dust-tight separation between the wet room and the dry room.
- the invention is based on the technical problem of further developing a motor vehicle lock and in particular a motor vehicle door lock of the configuration described at the outset in such a way that the electric motor drive can be designed to be particularly low-power, so that weight and cost advantages are observed compared to the prior art.
- a generic motor vehicle lock and in particular a motor vehicle door lock is characterized within the scope of the invention in that both housing parts of the housing are arranged parallel to one another and are sealingly connected to one another at the edges.
- the invention uses a special topological orientation of the two housing parts. These are namely - in contrast to the generic prior art according to EP 2754799 B1 - not perpendicular or L-shaped to each other, but parallel.
- This provides a particularly compact form of the housing consisting of the two housing parts, which can be sealed off from the environment in a particularly simple manner because the two housing parts are sealed to one another at the edges are connected, consequently the housing has the desired dust and moisture-proof encapsulation.
- the electric motor drive usually works on the locking mechanism and is therefore designed as an electric motor opening drive. In principle, however, the electric motor drive can also be used for other functions, for example as a locking drive.
- the electric motor drive usually has a driver lever, which extends through a passage between the two housing parts.
- the driver lever regularly interacts with a release lever, which in turn lifts the pawl from its locking engagement with the rotary latch in the closed state of the locking mechanism in the example case.
- an actuating lever is usually also implemented, which is coupled to the driver lever.
- the electric motor drive can be designed to be small and inexpensive, because this usually means that only small operating forces are required to open the locking mechanism and, moreover, due to the arrangement of the electric motor drive in the dry housing part, wear due to environmental pollution practically does not occur for the reasons already described.
- the actuating lever, the driver lever and also the release lever are usually made of plastic, so that a solution that is both weight-optimized and cost-effective is available.
- this allows the passage between the two housing parts to be designed particularly advantageously and, in particular, tightly. In fact, the passage is regularly the only connection between the two housing parts. If the passage is therefore designed to be sealed, any moisture or dust from the wet room housing part cannot get into the dry room housing part.
- the passage is advantageously designed as a rotary feedthrough with a seal.
- the design can also be made such that the seal is supported on the driver lever and rests against an upper side of the wet room housing part.
- the seal may be present and implemented as a separate component.
- the seal can also define a structural unit together with the driver lever.
- the seal is attached to or molded onto the driver lever, for example by means of an adhesive connection or in such a way that the seal is molded onto the driver lever. Such a procedure is particularly recommended in the event that the driver lever is made of plastic and the seal, which is also made of plastic, is molded onto it.
- At least one separate seal can also be provided for sealing the two housing parts in the edge area.
- the two housing parts it is also possible to connect the two housing parts to one another in a materially bonded manner in the edge region.
- the housing as a whole and, consequently, the two housing parts are generally made of plastic and designed as plastic injection-molded parts. Accordingly, such an integral connection in the edge area of the two housing parts can be realized in such a way that the plastic of the housing, for example, in the edge area is melted at certain points by a welding process (including ultrasonic welding or laser welding), thereby ensuring the material connection of the two housing parts at this point.
- a welding process including ultrasonic welding or laser welding
- a motor vehicle lock and in particular a motor vehicle door lock is made available which first of all ensures particularly reliable and low-friction operation of the electric motor drive due to its arrangement in the dry room housing part. Since, according to the invention, both housing parts are arranged parallel to one another and are sealingly connected to one another at the edges, an encapsulated design for the housing is provided overall and the desired low-power operation of the electric motor drive is further supported. This is where the main advantages can be seen.
- Fig. 1 the motor vehicle lock according to the invention in a perspective overview
- Fig. 2 is a plan view of the object of FIG. 1 and
- Fig. 3 shows a cross section through the object according to Figures 1 and
- a motor vehicle lock is shown, which is not limited to a motor vehicle door lock, which is placed in or on a motor vehicle door, not shown.
- the motor vehicle door lock shown has one that can only be seen in FIG Locking mechanism 1, 2 consists essentially of a rotary latch 1 and pawl 2.
- the locking mechanism 1, 2 is mounted in a lock case 3, which is attached to or connected to a housing 4, 5.
- the housing 4, 5 is designed in two parts and has a wet room housing part 4 and a dry room housing part 5. Since the locking mechanism 1, 2 with the lock case 3 is attached to the wet room housing part 4 or belongs to it, the wet room housing part 4 not protected against dust or splashing water in particular. Because the lock case 3 has, as usual, an infeed mouth, not expressly shown, via which a locking bolt can move into the locking mechanism 1, 2 and interact with it in a known manner. In contrast, the dry room housing part 5 is sealed against spray water and dust.
- the basic structure also includes an electric motor drive 6, 7, which is located in the dry room housing part 5.
- the electric motor drive 6, 7 works on an actuating lever chain 8, 9, which is composed of an actuating lever 8 and a driver lever 9 according to the embodiment.
- the electric motor drive 6, 7 consists of an electric motor 6 on the one hand and a driven pulley 7 on the other hand.
- the electric motor 6 is equipped on its output shaft with a worm, which meshes with a toothing of the output disk 7 on the outer circumference, so that the latter can be rotated.
- the driven pulley 7 has a helical actuating contour on its rear surface, which cannot be seen in FIG Axis 9b completed.
- the axis 9b of the actuating lever 8 is formed by a bearing pin 9b of the driver lever 9, which engages in the actuating lever 8. Since the actuating lever 8 and the driver lever 9 are coupled to one another in a rotationally fixed manner, the anti-clockwise rotation of the actuating lever 8 in the illustration according to Fig. 1 to open the locking mechanism 1, 2 results in the arm 9a on the driver lever 9 in the sectional illustration according to Fig. 3 is moved out of the drawing plane in the direction of the viewer. The consequence of this is that the pawl 2 is lifted from its latching engagement with the catch 1 . A previously caught locking bolt is released as a result.
- the control unit 10 is part of a circuit board 12 which, like the control unit 10, is located in the dry room housing part 5.
- the emergency energy source 11 is also arranged on the printed circuit board 12 and, according to the exemplary embodiment, consists of two supercapacitors which are consequently also arranged in the dry space housing part 5 .
- the electric motor drive 6, 7 is protected in the dry housing part 5, but also the control unit 10, the emergency energy source 11 and also the circuit board 12 with the other electrical/electronic components located thereon and not expressly shown.
- the housing 4, 5 is at least in two parts with the locking mechanism 1, 2 receiving wet room housing part 4 and the dry room housing part 5, in which the electric motor drive 6, 7 and the control unit 10 and beyond the emergency power source 11 and finally the circuit board 12 are located.
- the two housing parts 4, 5 are now arranged parallel to one another and are connected to one another in a sealing manner at the edges, as can best be understood from the sectional view in FIG.
- the electric motor drive 6, 7 works on the locking mechanism 1, 2, according to the exemplary embodiment in such a way that at this point the actuating lever chain 8, 9 with the actuating lever 8 and the driver lever 9 are interposed.
- the electromotive drive 1 , 2 acts on the driver lever 9 which, in order to act on the locking mechanism 1 , 2 , extends through a passage 13 between the two housing parts 4 , 5 .
- the passage 13 represents the only connection between the two housing parts 4, 5.
- the passage 13 is designed as a rotary feedthrough with a seal 14.
- the driver lever 9 reaches through the relevant passage 13 or the rotary feedthrough 13 with the seal 14 with its bearing pin 9b .
- the driver lever 9 is equipped with a radial projection 9c relative to the bearing journal 9b.
- the design is also such that the upper side of the wet room housing part 4 is equipped with a vertically drawn-down annular wall 4a, which overall defines an annular housing open towards the bottom, in which the seal 14 together with the radial support 9c of the driver lever 9 is recorded.
- the arm 9a of the driver lever extends radially outwards, with the help of which the driver lever 9 acts on the locking mechanism 1, 2.
- the previously mentioned and provided in the rotary union 13 seal 14 can be generally formed as a separate component.
- the driver lever 9 and said seal 14 define a structural unit 9, 14.
- the driving lever 9 is made of plastic.
- the actuating lever 8. This makes it possible for the seal 14, which is also made of plastic, to be molded onto the driver lever 9, which is also made of plastic, and this can be realized and implemented overall in a so-called two-component injection molding process.
- a solid plastic for the driver lever 9 and an elastic plastic for the seal 14 are processed together and connected to each other.
- the housing 4, 5 is also made of plastic, with the two housing parts 4, 5 each being plastic injection molded parts.
- the two housing parts 4, 5 are equipped in their edge region 15 with a seal is not provided.
- the edge area 15 there is the possibility in the edge area 15 that the two housing parts 4, 5 are connected to one another with a material fit.
- the two housing parts 4, 5 are each equipped in the edge area with an interlocking U-shaped profile.
- the seal already mentioned or a casting compound 16 indicated in FIG. 3 can be used at this point.
- the two housing parts 4, 5 it is also possible for the two housing parts 4, 5 to be (ultrasonic) welded to one another in the edge region 15. It is just as possible for the seal (not shown) to be molded onto one or both housing parts 4 in the edge area 15 . Combinations are also conceivable.
- a two-component injection molding process can be used. Because the respective housing part 4, 5, like the seal, is made of plastic, so that the said elements can pass through allow the mentioned two-component injection molding process to be connected to one another in a cohesive manner.
