Description

Technical Field

[0001]

[0001] The present invention relates to an automotive lock having an electronic control device, the control device comprising a circuit board, electronic components connected to the circuit board and arranged in a first plane, and an energy storage device connected to the circuit board.

[0002]

[0002] An automotive lock is understood to mean an automotive lock that can be arranged on different automotive parts. The automotive lock, in particular the locking mechanism of the automotive lock, interacts with the locking bolt as soon as the associated automotive door, automotive hatchback, automotive side door, etc. are closed. For this purpose, the automotive lock is usually arranged inside or on the automotive door in question. In contrast, the locking bolt is placed on the body, for example, on the B or C pillar. The locking bolt, which can also be called a lock holder, and the automotive lock together define a lock for an automotive door.

[0003]

[0003] Modern automotive locks include a plurality of functions such as, for example, a central locking system, a child lock, anti-theft protection, or collision protection. These functions, on the one hand, take over safety-related functions or improve the comfort of the vehicle. In most cases, these functions are powered or actuated indirectly or directly by an electric motor. To control these automotive locks, the automotive locks include an electronic control device. Conventionally, an electronic control device for controlling an automotive lock consists of a circuit board, electronic components arranged on the circuit board, and an energy storage device. The electronic control device is usually also arranged on an automotive door, the tailgate of the vehicle, the side door of the vehicle, etc. For this reason, the electronic control device needs to be sufficiently miniaturized so that it can be installed in a space-saving manner on an automotive door, the rear door of the vehicle, the sliding door of the vehicle, etc.

[0004]

[0004] In an electronic control device for controlling the movement of a side window, a vehicle lock, or a lifting device today, to give some applications as an example, the required installation space is due to the dimensions of the circuit board arranged within the electronic control device, because the circuit board has all the essential electronic components. Conventionally, the electronic components and the energy storage device have been arranged flatly adjacent to each other on the circuit board in order to enable a very flat and space-saving design.

[0005]

[0005] A very space-saving design is also known from EP 3 337 008 A2. This publication discloses a circuit board that can be fixed on one side and arranged within a control box. The narrow embodiment is achieved by the positioning of the electronic components. The energy storage device is arranged flatly adjacent to the electronic components on the circuit board. Due to the flat design, it can be installed within an active or non-active leaf or within a frame.

[0006]

[0006] The electronic control device of a vehicle lock known from the prior art can be installed on a flat door or frame of a vehicle due to its flat design. However, since the flat design requires sufficient space because the electrical components are arranged adjacent to each other, it requires a large base area. The base area is understood to mean the area of the electronic control device that basically results from the area of the circuit board based on the length and width of the circuit board. Also, if there is not enough space to install a wide but flat electronic control device within a vehicle, there are limitations with the electronic control devices and power supply devices described in the prior art, and they cannot be installed. This is where the invention begins.

Summary of the Invention

[0007]

[0007] The object of the present invention is, in particular, to provide an improved electronic control device for controlling a motor vehicle lock. In particular, the object of the present invention is to provide an electronic control device for controlling a motor vehicle lock that can be installed even when the base area is small and thus the available installation space is small. Furthermore, the object of the present invention is to ensure the safe storage of electrical components.

[0008]

[0008] The object of the present invention is achieved by the features of the independent claims. Advantageous embodiments of the present invention are described in the dependent claims. It should be noted that the exemplary embodiments described below are not limiting, but rather any possible variations of the features disclosed in the description, the dependent claims, and the drawings are possible.

[0009]

[0009] Accordingly, the object of the present invention is achieved by a motor vehicle lock having an electronic control device designed to control, in particular, motor vehicle locks, door openers, etc., the control device having a circuit board connected to a circuit board having electronic components arranged in a first plane, and an energy storage device connected to the circuit board, the energy storage device being arranged at least partially above the electronic components in a second plane offset from the first plane.

[0010]

[0010] The arrangement of the electronic components and the energy storage device of the present invention, also called a control electronics, ensures that the base area of the electronic control device or the area of the circuit board is reduced compared to conventional electronic control devices, since the electronic components and the energy storage device are arranged one above the other. The height of the electronic control device is only slightly increased by the proposed two-plane structure. This is because the energy storage device is usually flat and designed to have a low height. The compact design not only makes it possible to install on door elements with only limited available space, but also makes the electronic control device, and thus the motor vehicle lock, more robust and lightweight due to its reduced size.

[0011] When the term "door element" is used in the sense of the present invention, this term refers in particular to components that are movably arranged on a motor vehicle, held in a position fixed by a motor vehicle lock, and / or can be actuated by electric drive. This can be a side door, a hood, a sliding door, a hatchback, a cover, or an equivalent component of a motor vehicle. By means of an electric drive device, in a motor vehicle lock, it is possible to carry out locking, unlocking, child protection, release, or equivalent functions, the functions being operated by an electric motor and thus requiring an electrical energy supply.

[0012]

[0012] Although the present invention is mainly referred to in the description with reference to a control device for a motor vehicle lock, this should not be understood as a limitation. The control device can be used, for example, not only for controlling a charging lock but also in other areas of the motor vehicle.

[0013] In the context of the present invention, when referring to "above" or "one above the other", this particularly means that the two planes are not identical, do not intersect, are spaced apart from each other, are spatially offset, particularly in the direction of the normal of the plane, and / or are arranged substantially parallel to each other. This provides a two-plane structure in which the two planes are particularly arranged one above the other in a layered manner. In the prior art, electronic components are usually arranged adjacent to each other on a circuit board of an electronic control device. However, the essential point of the present invention is that in an electronic control device used according to the present invention, an energy storage device on a circuit board, also called a printed circuit board, is at least partially arranged above the electronic components. In a normal design, the circuit board preferably has conductive tracks, and electrical components such as microswitches can be connected to each other by the conductive tracks. Basically, the base area of the electronic control device due to the area of the circuit board can be reduced by the two-plane structure. The arrangement of the electrical components on the circuit board is preferably on one side. This means that the electronic components are equipped only on one side of the circuit board. It is also possible to equip both sides of the circuit board with electronic components and the like.

[0014]

[0014] When the energy storage device and the electronic components are arranged one above the other at least partially coinciding in the first plane and the second plane, an advantageous embodiment can be provided again. This reveals an important advantage of the present invention, namely that the base area of the circuit board is just large enough for the electronic components arranged thereon. Conventionally, an energy storage device that would occupy a relatively large space on the circuit board is arranged at least partially coinciding, preferably completely coinciding, in a second plane above the electronic components. The energy storage device of the control device is preferably positioned to be arranged in a second plane in the z-direction above the electronic components. The z-direction is preferably the direction in which the longitudinal axis of the control device is oriented. The z-direction is preferably oriented perpendicular to the surface normal of the circuit board. By adopting the two-plane structure, the base area of the control device can be reduced.

[0015]

[0015] In principle, various energy storage devices can be used as the energy storage device in connection with the present invention. However, according to a variant of the preferred embodiment, the energy storage device comprises an ultracapacitor or a supercapacitor, also called an "ultracap".

[0016]

[0016] When placing the energy storage device on top of an electronic component, it is advisable to fix it in a stable manner due to the substantial weight of the energy storage device. In addition to the energy storage device, possible contact units of the electronic control device, for example, a circuit board connector, also called a circuit board plug-in connector, are one of the relatively heavy components, and stable fixation is necessary to prevent these heavy components from breaking or being damaged, especially in the case of strong acceleration or vibration.

[0017]

[0017] A variant of an embodiment of the present invention can be advantageously formed when an electronic control device as part of an automotive lock has a housing and a housing cover disposed thereon, a circuit board having electronic components and an energy storage device are disposed within the housing, and the energy storage device is held in place by the housing and / or the housing cover. The bottom of the housing or the housing preferably can form a first plane, and the housing cover preferably can form a second plane, such that the housing cover or the second plane is disposed above the housing bottom or the first plane. However, it is also possible that the housing cover is disposed above the second plane and surrounds the energy storage device disposed within the second plane.

[0018]

[0018] Thereby, the heavy energy storage device can be stably installed.

[0019]

[0019] Also advantageously, the housing and / or the housing cover contain plastic and / or metal. The plastic material and / or metal enable various different stable fixing options for the energy storage device within the housing and / or the housing cover.

[0020]

[0020] Moreover, a variant of an embodiment of the present invention can be advantageously formed if the housing and / or the housing cover have a recess into which the energy storage device can be inserted and can be installed in a predetermined position by closing the housing cover. Preferably, the energy storage device is connected to the circuit board on a first side and installed in a predetermined position on a second side. In a variant of this embodiment, the installation is preferably performed by positioning one side of the energy storage device on and / or within the recess of the housing and / or the housing cover such that the energy storage device is installed in a plane parallel to the circuit board in a horizontal direction. By closing the housing with the housing cover, the energy storage device can also be installed in a predetermined position in a vertical position.

[0021]

[0021] The recess of the housing and / or the housing cover are preferably designed as a holding device, and the holding device is formed, for example, by the outer shape of the storage within the housing. Protrusions are designed on the housing, and the outer shape thereof matches the outer shape of the component to be held. Next, the component to be held can be set on the protrusion by a shape-conforming method. The holding device can also be formed, for example, by an intermediate element having a recess. Next, the components to be held can be guided within or through the recess so that they can be held by the intermediate element.

[0022]

[0022] Installation at a specified position can be achieved, for example, by clip - fixing the energy storage device within the recess, and / or by using clip - fixing and / or plug connection to attach the housing cover to the housing. The installation can also include screwing or adhesion.

[0023]

[0023] A further embodiment of the present invention is achieved when the energy storage device is at least partially injected into the housing. The energy storage device can be at least partially integrated within the housing and / or the housing cover. This integration is preferably performed by embedding the energy storage device into the plastic material of the housing and / or the housing cover. This embedding can be carried out, for example, by a plastic injection - molding process. Alternatively, it is possible to coat the housing and / or the housing cover with an epoxy resin or immerse them in an epoxy resin to embed the energy storage device in an epoxy resin layer. Preferably, other heavy electrical components, such as the contact unit of the electronic control device, are embedded because they require a particularly stable installation due to their high weight.

[0024]

[0024] In a variant of a further embodiment of the present invention, the energy storage device is at least locally held within an elastic bearing. In particular, the elastic bearing of a heavy energy storage device is advantageous in the case of vibrations occurring during vehicle operation. The elastic bearing within the elastic plastic can elastically absorb the kinetic energy of the energy storage device. The elastic holder of the energy storage device can be locally arranged around the perimeter of the energy storage device, so that the shape - conforming receptacle of the energy storage device can ensure firm holding. The elastomer can locally accommodate and hold the energy storage device at one or several regions. Preferably, a cylindrical energy storage device that is held in a shape - conforming and at least partially circular manner within the elastomer material is used.

[0025]

[0025] When the elastic bearing is designed as a separate component and / or as an integrated part of the housing, a variant of an advantageous embodiment of the present invention can be achieved again. The elastomer used as a bearing, i.e., the elastic material, can be shaped and fitted into the housing of the automotive lock as a separate component. This results in a variant of the embodiment where the energy storage device can be arranged locally only on the circuit board because the elastomer in the housing forms a bearing point for the energy storage device. Of course, the bearing point can also be arranged in a recess of the circuit board so as to provide, for example, an elastic bearing for the energy storage device. The elastomer material can be inserted into the housing as an independent component, especially into the dry space of the automotive lock, or can form an integral part of the housing. For example, when different materials are manufactured with one tool and made available as a bearing point for the energy storage device, a two-component injection molding process is advisable. Preferably, two energy storage devices are used and a single separate component can be used, which can be inserted into the housing in a shape-conforming manner, for example, and then can provide, for example, a shape-conforming receptacle for the energy storage device. Although two energy storage devices are preferably mentioned, it is of course also possible to accommodate only one energy storage device or more than two energy storage devices in the automotive lock. In a further variant of the embodiment, the energy storage device can be fixed by the housing cover and the elastic bearing. The elastic region can be arranged locally around the energy storage device or the energy storage device so as to preferably provide a shape conformity to the energy storage device. The elastic regions can also be arranged to face each other in the diameter direction, for example, to mount the energy storage device on both sides. On the one hand, it is possible to directly contact the energy storage device by the housing cover and hold or fix them against the elastic bearing, and on the other hand, it is also possible to provide an elastic bearing or a receptacle for the energy storage device on the housing cover so that, for example, the energy storage device is mounted on at least two sides of the elastic material.

[0026]

[0026] The elastic material or elastic bearing of the energy storage device can be made of an elastic material such that an initial stress can be generated by the housing through the energy storage device in the elastic material and through the housing cover. The elastic material can also have a rib structure, for example, so that the energy storage device is held at several support points or receiving lines in the elastic material. Thereby, the attenuation rate can be adjusted, and at the same time, the weight of the elastomeric damping body can be minimized.

[0027]

[0027] Also, when the energy storage device is connected to the circuit board by at least a local elastic connection, it is advantageous to form a variant of a further embodiment of the present invention. The connection of the energy storage device via a spring-loaded contact or at least a partially spring-loaded contact makes it possible in this case to cushion any movement occurring in the heavy energy storage device via the electrical connection. In other words, the movement of the energy storage device that occurs can be kept away from the circuit board. Therefore, the movement of the energy storage device is not transmitted to the printed circuit or the circuit board and is absorbed by the elastic connection. This means that, on the one hand, an elastic bearing for the energy storage device can be provided, and on the other hand, the circuit board can be protected from stress due to the movement of the energy storage device.

[0028]

[0028] Furthermore, a method for producing an electronic control device for controlling an automotive lock according to the present invention is provided. In a first step, a circuit board is arranged, and electronic components are arranged in a first plane thereon and connected to the circuit board. In a second step, an energy storage device connected to the circuit board is arranged at least partially above the electronic components in a second plane offset from the first plane. As a result, a circuit board is produced in which the electronic components are arranged in the first plane and the energy storage device is arranged in the second plane partially above the electrical components.

[0029]

[0029] Advantageously, in a further step, a circuit board having electronic components and an energy storage device is inserted into a housing, the housing positioning at least the energy storage device in a predetermined position. For example, the energy storage device is clamped by the housing or the energy storage device is clipped into the housing.

[0030]

[0030] Advantageously, in a further and / or alternative step, to obtain the housing, the circuit board having electronic components and an energy storage device is overmolded with plastic. The energy storage device is preferably overmolded with plastic such that the energy storage device becomes an integral part of the housing and / or the housing cover and is thus positioned in a predetermined position.

[0031]

[0031] In a further advantageous method step, the energy storage device is at least locally arranged within an elastic bearing. Advantageously, by inserting the energy storage device into the elastic bearing, sensitive components can be prevented from being overloaded. In addition, the elastic receptacle enables the insertion of the energy storage device into the elastic bearing to form a balance with respect to the circuit board. Advantageously, the energy storage device is also connected to the circuit board by elastic contacts.

[0032]

[0032] Further embodiments and advantages of a method similar to the control device described above will be apparent to those skilled in the art.

[0033]

[0033] Hereinafter, based on preferred embodiments of the present invention, the present invention will be described in more detail with reference to the accompanying drawings. However, the exemplary embodiments do not limit the present invention, and the principle that they are merely advantageous embodiments applies. The features shown can be implemented individually or in combination, either individually or in combination with further features of the specification and the claims.

[0035] Detailed Description of the Invention

[0036]

[0035] In FIG. 1, a circuit board 2 of a conventional electronic control device is shown in a plan view. On the circuit board 2, an electronic component 3, an energy storage device 4, and a contact unit 8 are arranged adjacent to each other on the same plane.

[0037]

[0036] In FIG. 2, a housing cover 6 of an electronic control device 1 according to an embodiment of the present invention is shown in a plan view. Different from the circuit board 2 of the prior art shown in FIG. 1, the energy storage device 4 and / or the contact unit 8 are at least partially integrated into the housing cover 6. This means that the energy storage device 4 and / or the contact unit 8 are connected to the housing cover 6 by shape and / or force fitting. Further, as will be described later, above an electronic component 3 (not shown) arranged on the circuit board 2, an energy storage device 4 integrated into the housing cover 6 is arranged.

[0038]

[0037] The energy storage device 4 and / or the contact unit 8 can be pushed into a recess or an opening provided in the housing cover 6 and / or, for example, can be mounted on the housing cover 6 by adhesion and / or screwing. Alternatively, the energy storage device 4 and / or the contact unit 8 may be at least partially integrated into the plastic material of the housing cover 6 by injection. For example, in a plastic injection molding process, the energy storage device 4 and / or the contact unit 8 can be an integral component of the housing cover 6 formed from the plastic material.

[0039]

[0038] Alternatively, the energy storage device 4 and / or the contact unit 8 may be at least partially integrated not within the housing cover 6 but within the housing 5, so that the energy storage device 4 and / or the contact unit 8 are connected to the housing 5 in a form-fitting and / or force-fitting manner. For this purpose, for example, the energy storage device 4 and / or the contact unit 8 are pushed into a recess or an opening provided in the housing 5 for this purpose and / or, for example, are mounted by adhesion and / or screwing and / or, for example, by closing the housing 5 with the housing cover 6.

[0040]

[0039] FIG. 3 shows a perspective view of an electronic control device according to a preferred embodiment of the invention. The energy storage device 4 and the contact unit 8 are partially integrated into the housing 5 as will be described in detail below. The circuit board 2 is arranged within the housing 5 of the electronic control device 1. On the circuit board 2, the contact unit 8 and the electronic components 3 are arranged in a first plane. The energy storage device 4 is arranged in a second plane above the first plane, i.e., above the electronic components 3, and is connected galvanically to the circuit board via an electrical contact 9. As with other conventional circuit boards, although not shown here, the conductive tracks for contacting the electronic components 3 and the energy storage device 4 are embedded in the circuit board 2.

[0041]

[0040] The energy storage device 4 is aligned with their longitudinal axes along the z direction shown in FIG. 3. Since the energy storage device 4 is arranged above the electronic components 3, the base area is reduced compared to the designs known from the prior art. The recess 7 of the housing 5 represents the integrated holding device 10. The energy storage device 4 is form-fittingly inserted into the recess 7 by its ends. For this purpose, the recess 7 is shaped according to the outer shape of the energy storage device 4. Thus, one end of the energy storage device 4 is connected to the circuit board 2 via the electrical contact 9, and the other end is installed via the recess 7 of the housing 5.

[0042]

[0041] The base area of the electronic control device 1 is basically due to the area of the circuit board 2 defined by the length of the circuit board 2 in the z direction and the width in the x direction in FIG. 3. The energy storage device 4 is not arranged adjacent to the electronic components 3 like the electronic control device of a conventional automotive lock as shown in FIG. 1, but rather above them, so the area of the circuit board 2 or the base area of the electronic control device 1 is significantly reduced.

[0043]

[0042] Since the energy storage device 4 is arranged above the electronic components 3, the electronic control device 1 has a slightly higher height than the electronic control device of a conventional automotive lock. The height of the electronic control device 1 extends in the y direction in FIG. 3. However, since the energy storage device 4 is usually designed to be relatively flat, the increase in height is small. Also, since the base area becomes smaller, materials can be saved and the electronic control device 1 can be manufactured more economically.

[0044]

[0043] The two-plane structure is illustrated in FIG. 4. FIG. 4 shows a cross-sectional view of the electronic control device 1 as seen from FIG. 3 along the cutting axis X-X shown in FIG. 3. The electronic component 3 is arranged on the first plane A on the circuit board 2. One of the energy storage devices 4 is arranged on the second plane B above the electronic component 3. The plane A and the plane B are each spanned by a vector in the z direction and a vector in the x direction. The x direction is not shown in FIG. 4 for two-dimensional display. However, it is clear that the plane B is placed above the plane A. As a result, it is clear that the energy storage device 4 is arranged above the electronic component 3.

[0045]

[0044] The housing 5 surrounds the recess 7 and integrally forms the holding device 10. The energy storage device 4 is inserted into the recess 7. The energy storage device 4, together with the housing cover 6, is placed in a predetermined position by clamping the energy storage device between the recess 7 and the housing cover 6. According to the two-plane structure of the electronic control device 1 for controlling the automobile lock according to the present invention, by arranging the energy storage device 4 above the electronic component 3, the base area of the electronic control device 1 can be reduced, and miniaturization can be achieved.

[0046]

[0045] It is advantageous to place the energy storage device 4 and / or the contact unit 8 in a predetermined position by clamping, injection molding, adhesion, screwing, clipping, or, for example, coating or dipping with an epoxy resin. As a result, the energy storage device 4 and / or the contact unit 8, each of which can have a relatively high weight, are securely placed and will not break or otherwise be damaged even in the case of high acceleration and / or vibration.

[0047]

[0046] FIG. 5 depicts a cross-section through the automotive lock 11 constructed in accordance with the present invention in a cross-section through the circuit board 12, the housing 13, the housing cover 14, and the energy storage devices 15, 16. In this exemplary embodiment, the energy storage devices 15, 16 are arranged in a second plane C-C, and the circuit board 12 is arranged in a first plane D-D. The energy storage devices 15, 16 are received in form-fitting engagement within the elastic bearing 17, and the elastic bearing in this exemplary embodiment is rib-shaped. By means of the ribs 18, a linear contact between the elastic material 17 and the energy storage devices 15, 16 can be realized. In order to safely carry or mount the energy storage devices 15, 16, the energy storage devices are mounted between the housing cover 14 and the elastic material 17. Also, in the exemplary embodiment, the elastic bearing 17 is received in form-fitting engagement within the recess 19 of the housing 13. Thus, in the present embodiment, the elastic bearing 1 is shown as a separate component. In this case, the mounting of the energy storage devices 15, 16 is achieved by pressing the housing cover 14 against the energy storage devices 15, 16, and as a result, by the contact force of the energy storage devices 15, 16 against the elastic bearing 17. As can clearly be seen, the planes C-C and D-D are spaced apart from each other, and the energy storage devices are arranged only locally above the circuit board 12. The electrical contact of a part of the energy storage devices 15, 16 and the circuit board 12 is not shown in this exemplary embodiment. The electrical components 20 on the circuit board 12 can be seen, and the circuit board 12 also extends beneath the energy storage devices 15, 16. In this exemplary embodiment, the energy storage devices 15, 16 are arranged only locally above the circuit board 12.

[0048]

[0047] Also, in FIG. 5, a part of the mechanism 21 of the automotive lock 11 can be seen, and this mechanism 21 is arranged separated from the dry space 23 of the circuit board 12 by the partition wall 22. The energy storage devices 15, 16, the electrical components 20, and the circuit board 12 are placed in the dry space of the automotive lock 11, i.e., the mechanism 21 is arranged so as to be sealed against the electrical components 20, 15, 16, and the elastic bearing 17 within the automotive lock 11.
