Description

Technical Field

[0001] The invention relates to a motor vehicle lock having an electronic control device, the control device having a circuit board and an energy storage device connected to the circuit board, the circuit board having electronic components arranged on the circuit board in a first level and connected to the circuit board. Background Art

[0002] A motor vehicle lock is understood to be a lock for a motor vehicle, which can be arranged in different parts of the motor vehicle. As soon as the associated motor vehicle door, motor vehicle hatch, motor vehicle sliding door, etc. is closed, the motor vehicle lock or in particular the locking mechanism of the motor vehicle lock interacts with the locking pin. For this purpose, the motor vehicle lock is usually arranged in or on the relevant motor vehicle door. In contrast, the locking pin is located on the vehicle body, for example on the B-pillar or C-pillar. The locking pin, also called lock holder, and the motor vehicle lock together define the motor vehicle door lock.

[0003] Today's motor vehicle locks contain a variety of functions, such as central locks, child safety locks, anti-theft protection locks or collision protection locks, which assume safety-related functions or increase the comfort of the motor vehicle. These functions are usually driven, connected or set directly or indirectly by electric motors. In order to control these motor vehicle locks, the motor vehicle locks include an electronic control device. The electronic control device for controlling the motor vehicle lock usually includes a circuit board and electronic components arranged on the circuit board and includes an accumulator. The electronic control device is also usually arranged in a motor vehicle door, a motor vehicle hatch, a motor vehicle sliding door, etc. Therefore, the size of the electronic control device must be small enough so that it can be installed in a motor vehicle door, a motor vehicle hatch, a motor vehicle sliding door, etc. in a space-saving manner.

[0004] In today's electronic control devices for controlling the movement of side windows, motor vehicle locks or opening devices (to name just a few applications), the required installation space is determined by the size of the circuit board arranged in the electronic control device, because the circuit board carries all the necessary electronic components. Traditionally, the electronic components and energy storage devices are arranged side by side on the circuit board in order to achieve a design that is as flat and space-saving as possible.

[0005] A design that saves as much space as possible is also known from EP 3 337 008 A2. This document discloses a circuit board that is mounted on one side and can be arranged in a control box. The arrangement of the electronic components allows a narrow implementation. The energy storage device is placed flat on the circuit board next to the electronic components. The flat design allows installation in the frame of a door panel or a moving or fixed leaf.

[0006] The electronic control devices in motor vehicle locks known from the prior art can be installed in flat doors or frames of motor vehicles due to their flat structural design. However, the flat structural design is accompanied by a wide base area, since the electrical components are arranged adjacent to each other and accordingly require sufficient space. The base area is understood to be the area of ​​the electronic control device that is mainly generated by the area of ​​the circuit board due to the length and width of the circuit board. In the case of insufficient structural space in the motor vehicle for a flat but wide electronic control device, the electronic control device or energy supply device described in the prior art encounters limitations and cannot be installed. The present invention is intended to solve this technical problem. Summary of the invention

[0007] The object of the present invention is to provide an improved electronic control device, in particular for controlling a motor vehicle lock. In particular, the object of the present invention is to provide an electronic control device, in particular for controlling a motor vehicle lock, which has a reduced footprint and can therefore also be installed when only a small amount of installation space is available. Furthermore, the object of the present invention is to ensure safe storage of electrical components.

[0008] The objects of the invention are achieved by the features of the independent claims. Advantageous embodiments of the invention are described in the dependent claims. It is pointed out that the embodiments described below are not restrictive; on the contrary, any feasible variation of the features disclosed in the description, the dependent claims and the drawings is possible.

[0009] Therefore, the object of the present invention is achieved by a motor vehicle lock with an electronic control device, which is designed to control in particular a motor vehicle lock, a door opener, etc., wherein the control device has a circuit board, electronic components arranged on the circuit board in a first layer, and an energy accumulator connected to the circuit board, the electronic components are connected to the circuit board, and the energy accumulator is arranged in a second layer offset from the first layer and at least partially arranged above the electronic components.

[0010] The arrangement according to the invention of the electronic components and the energy storage device (also referred to as the control electronics) ensures that the base area or the area of ​​the circuit board of the electronic control device is smaller than that of conventional electronic control devices, since the electronic components and the energy storage device are arranged one above the other. Since the energy storage device is usually flat and low in height, the proposed two-layer structure increases the height of the electronic control device only slightly. Due to this compact design, not only is installation in the door element possible with only a small amount of available installation space, but the electronic control device and therefore the motor vehicle lock are more stable / robust and lighter due to the reduced size.

[0011] When a door element is mentioned in the context of the present invention, in particular a component which is arranged movably on the motor vehicle and is held in a fixed position by a motor vehicle lock and / or can be actuated by an electric drive. The door element can be a side door, a hood, a sliding door, a tailgate, a cover on the motor vehicle or a similar component. The electric drive can be used to realize locking, unlocking, childproofing, unlocking or similar functions in a motor vehicle lock which is operated by an electric motor and therefore requires an electric power supply.

[0012] Even if the invention is presented in the description primarily in conjunction with a control device for a motor vehicle lock, this should not be understood restrictively. The control device can also be used in other areas of the motor vehicle, for example for controlling a charging plug lock.

[0013] In the sense of the present invention, if the term "above" or "arranged above and below" is used, this means in particular that the two levels are not identical, do not intersect, are spaced apart from each other, are partially offset, in particular are offset in the direction of the level normal, and / or are arranged almost parallel to each other. Thus, a two-layer structure is provided, in which the two levels are arranged above and below in layers. In the prior art, electronic components are usually arranged adjacent to each other on a circuit board of an electronic control device. However, the main point of the present invention is that in the electronic control device used according to the present invention, the energy storage device on the circuit board (also called printed circuit board) is at least partially arranged above the electronic components. In the usual construction mode, the circuit board preferably has an electrical conductor line, by means of which electrical components such as micro switches can be connected to each other. The base area of ​​the electronic control device (mainly obtained by the area of ​​the circuit board) can be reduced by a two-layer structure. The electronic components are preferably arranged on one side of the circuit board. This means that the electronic components are only mounted on one side of the circuit board. The circuit board can also be equipped with electronic components on both sides, etc.

[0014] If the energy storage device and the electronic components are arranged at least partially one above the other in the first and second planes, an advantageous embodiment can be provided. This shows a significant advantage of the present invention, namely that the base area of ​​the circuit board can be just large enough to arrange the electronic components on the circuit board. The energy storage device, which usually occupies a large space on the circuit board, is arranged at least partially one above the other, preferably completely one above the other, in the second plane above the electronic components. The energy storage device of the control device is preferably positioned so that the energy storage device is arranged in the second plane above the electronic components in the z direction. The z direction is preferably the direction in which the longitudinal axis of the control device is facing. The z direction is preferably perpendicular to the surface normal of the circuit board. Due to the two-layer structure, the base area of ​​the control device can be reduced.

[0015] In principle, within the scope of the invention, various energy accumulators can be used as energy accumulators. However, according to a preferred design variant, the energy accumulator comprises a supercapacitor, also called an ultracapacitor or "supercapacitor".

[0016] When the energy accumulator is arranged above the electronic components, it is expedient to fix the energy accumulator stably due to its heavy weight. In addition to the energy accumulator, possible contact units of the electronic control device, such as circuit board plugs, also called circuit board connectors, are also relatively heavy components and require stable fixing to prevent these heavy components from breaking or being damaged, especially in the case of high accelerations or vibrations.

[0017] In a further variant of the invention, it is advantageous if the electronic control device as part of the motor vehicle lock has a housing and a housing cover arranged on the housing, the circuit board with the electronic components and the energy accumulator are arranged inside the housing, and the energy accumulator is fixed in a positionally fixed manner by the housing and / or the housing cover. The housing or the housing bottom can preferably form the first level, and the housing cover can preferably form the second level, so that the housing cover or the second level is arranged above the housing bottom or above the first level. However, the housing cover can also be arranged above the second level and surround the energy accumulator arranged in the second level.

[0018] This ensures that the heavy energy storage device is securely fixed.

[0019] It is also advantageous if the housing and / or the housing cover comprises plastic and / or metal. Plastic material and / or metal allow for a number of different possibilities for securely fixing the energy store in the housing and / or the housing cover.

[0020] It is also advantageous and constitutes a design variant of the invention if the housing and / or the housing cover has a recess into which the energy accumulator can be inserted and can be fixed in a position-free manner by closing the housing cover. The energy accumulator is preferably connected to the circuit board on a first side and fixed in a position-free manner on a second side. In this design variant, the fixing is preferably carried out by positioning one side of the energy accumulator on and / or in the recess in the housing and / or the housing cover, so that the energy accumulator is fixed in the horizontal direction in a plane parallel to the circuit board. By closing the housing with the housing cover, the energy accumulator can also be fixed in a position-free manner in the vertical direction.

[0021] The recess in the housing and / or the housing cover is preferably designed as a retaining device, which is formed, for example, by a storage contour in the housing. In this case, a projection is formed in the housing, the contour of which imitates the contour of the parts to be retained. The parts to be retained can then be placed on the projection in a form-fitting manner. The retaining device can also be formed, for example, by an intermediate element with a recess. The parts to be retained can then be extended into or through the recess so that the parts can be retained by the intermediate element.

[0022] For example, the fixed position fixing can be achieved by clipping the energy storage device into the recess and / or securing the housing cover to the housing by clipping and / or by a plug connection. The fixing can also include screwing or gluing.

[0023] If the energy accumulator is at least partially injection molded in the housing, another embodiment of the present invention is achieved. Here, the energy accumulator can be at least partially integrated into the housing and / or the housing cover. Preferably, the integration is achieved by embedding the energy accumulator in the plastic material of the housing and / or the housing cover. This embedding can be achieved, for example, by a plastic injection molding process. Optionally, the housing and / or the housing cover can be coated with epoxy resin or impregnated in epoxy resin, and the energy accumulator can be embedded in the epoxy resin layer. Preferably, other heavy electrical components, such as the contact unit of the electronic control device, are embedded here, because these components also need to be particularly stably fixed due to their heavy weight.

[0024] In another design variant of the invention, the energy accumulator is at least partially held in an elastomeric support. In particular, elastically supporting a heavy energy accumulator is particularly advantageous for vibrations that occur during the operation of a motor vehicle. Here, the elastic support in the elastomeric plastic can elastically absorb the kinetic energy of the energy accumulator. The elastic holding of the energy accumulator can be arranged in a partial area around the energy accumulator so that the form-locking reception of the energy accumulator can be reliably maintained. The elastomer can receive and hold the energy accumulator locally in a point-like manner or in multiple areas. Preferably, a cylindrical energy accumulator is used, which is received in the elastomeric material in a form-locking manner and at least in an arc-shaped manner.

[0025] If the elastomer support is designed as an independent component and / or an integral component of the housing, an advantageous design variant of the present invention can be achieved. The elastomer, i.e., the elastic material, used as the support can be received in the housing of the motor vehicle lock as an independent component and in a form-locking manner. This results in design variants in which the energy accumulator can also be arranged only in a local area above the circuit board, because the elastomer in the housing forms a support portion for the energy accumulator. Of course, the support portion can also be arranged in a notch in the circuit board, for example, so that an elastic support can be provided for the energy accumulator. The elastomer material can be placed in the housing as an independent component, in particular in the dry space of the motor vehicle lock, or the elastomer material can constitute an integral component of the housing. For example, a two-component injection molding process is suitable for use here, in which different materials can be manufactured in one mold and provide a support portion for the energy accumulator. Preferably, two energy accumulators are used, and at the same time, an independent component can be used, in which the independent component can be placed in the housing, for example, in a form-locking manner, and in turn, for example, a form-locking receiving portion can be provided for the energy accumulator. Even though two energy accumulators are preferred, it is of course also possible to accommodate only one energy accumulator or more than two energy accumulators in the motor vehicle lock. In another design variant, the energy accumulator can be fixed using a housing cover and an elastic bearing. The elastomer area can be arranged in a partial area around one or more energy accumulators, so that a form fit can preferably be provided for the energy accumulator. The elastomer areas can also be opposite, so that, for example, the energy accumulator can be fixed in two ways. On the one hand, the energy accumulator can be directly contacted by the housing cover and held or fixed relative to the elastic bearing, and on the other hand, the energy accumulator can also be provided with an elastic bearing or a receiving part on the housing cover, so that the energy accumulator can, for example, remain supported in the elastic material in at least two ways.

[0026] The elastomeric material or the elastic bearing of the energy accumulator can be made of an elastomeric material, so that a preload can be generated in the elastomeric material by the energy accumulator with the help of the housing cover. The elastic material can also have a rib structure, for example, so that the energy accumulator is held in the elastomeric material at a plurality of bearing points or receiving lines. This allows the damping rate / damping coefficient to be adjusted while the weight of the elastomeric vibration damping body is reduced to a minimum.

[0027] It is also advantageous if the energy accumulator is connected to the circuit board by means of an at least partially elastic connection, and this forms a further design variant of the invention. Here, the energy accumulator is connected via an elastic contact or an at least partially elastic contact, so that movements that may occur in the heavy energy accumulator can be damped by the electrical connection. In other words, any movement of the energy accumulator is prevented from contacting the circuit board. As a result, the movement of the energy accumulator is not transmitted to the printed circuit board or the circuit board, but is absorbed by the elastic connection. As a result, on the one hand, an elastic support can be provided for the energy accumulator, and on the other hand, the circuit board can be protected from loads caused by the movement of the energy accumulator.

[0028] Furthermore, a method for producing an electronic control device for controlling a motor vehicle lock according to the invention is provided. In this case, in a first step, a circuit board and electronic components arranged on the circuit board in a first level and connected to the circuit board are arranged. 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 level offset from the first level. Thus, a circuit board is produced on which the electronic components are arranged in the first level and the energy storage device is arranged in the second level and partially located above the electronic components.

[0029] In the next step, the circuit board together with the electronic components and the energy storage device is advantageously placed in a housing, and the housing at least fixes the energy storage device in a position-invariable manner. For example, the energy storage device is clamped by the housing, or the energy storage device is clipped into the housing.

[0030] Advantageously, in a further and / or alternative step, the circuit board together with the electronic components and the energy storage device are overmolded with plastic to obtain the housing. The energy storage device is preferably overmolded with plastic so that the energy storage device becomes an integral component of the housing and / or the housing cover and is therefore fixed in a positionally fixed manner.

[0031] In a further advantageous method step, the energy accumulator is arranged at least partially in the elastic support. Inserting the energy accumulator in the elastic support can advantageously protect sensitive components from overloading. Furthermore, by means of the elastic receiving portion, the energy accumulator can be advantageously balanced relative to the circuit board by placing it in the elastomeric support. The energy accumulator is also advantageously connected to the circuit board via an elastic contact.

[0032] Further embodiments and advantages of the method can be derived by a person skilled in the art in a manner analogous to the control device described above. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] 1 shows a printed circuit board 2 of an electronic control device according to the prior art in a top view. On the printed circuit board 2, electronic components 3, energy storage devices 4 and contact-making units 8 are arranged side by side in one level.

[0041] exist Figure 2 1 shows a housing cover 6 of an electronic control device 1 according to a preferred embodiment of the present invention in a top view. Unlike the circuit board 2 of the prior art shown in FIG. 1 , the energy storage device 4 and / or the contact unit 8 are now 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 in a form-fitting and / or force-fitting (friction-fitting) manner. In addition, the energy storage device 4 integrated in the housing cover 6 is arranged above the electronic components 3 located on the circuit board 2 (not shown here), as described further below.

[0042] The energy storage device 4 and / or the contact unit 8 can be pushed into a recess or opening provided in the housing cover 6 and / or fixed to the housing cover 6 by, for example, gluing and / or screwing. Alternatively, the energy storage device 4 and / or the contact unit 8 can be at least partially integrated into the plastic material of the housing cover 6 by injection molding. For example, during the plastic injection molding process, the energy storage device 4 and / or the contact unit 8 can become an integral component of the housing cover 6 molded from the plastic material.

[0043] Alternatively, the energy accumulator 4 and / or the contact unit 8 may not be integrated in the housing cover 6, but at least partially integrated in the housing 5, so that the energy accumulator 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 accumulator 4 and / or the contact unit 8 can be pushed into a recess or opening provided for this purpose in the housing 5, and / or fixed by, for example, gluing, and / or screwing, and / or by closing the housing 5 with the housing cover 6.

[0044] exist Figure 3 1 shows an electronic control device according to a preferred embodiment of the present invention in a perspective view. The energy storage device 4 and the contact unit 8 are partially integrated in the housing 5, as described in detail below. The circuit board 2 is arranged in 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, that is, above the electronic components 3, and is electrically connected to the circuit board via an electronic contact 9. As in other conventional circuit boards, electrical conductor lines for contacting the electronic components 3 and the energy storage device 4 are embedded in the circuit board 2, which are not shown here.

[0045] The longitudinal axis of the energy storage device 4 is Figure 3 The z-direction is shown. By arranging the energy storage device 4 above the electronic component 3, the base area is reduced compared to the designs known from the prior art. The recess 7 in the housing 5 forms an integrated retaining device 10. The energy storage device 4 is inserted into the recess 7 with its ends in a form-fitting manner. For this purpose, the recess 7 is shaped according to the contour of the energy storage device 4. The energy storage device 4 is therefore connected to the circuit board 2 at one end via the electronic contact 9 and is fixed at the other end by the recess 7 in the housing 5.

[0046] The basic area of ​​the electronic control device 1 mainly comes from the area of ​​the circuit board 2. Figure 3 In the embodiment, the area is defined by the length of the circuit board 2 in the z direction and the width of the circuit board in the x direction. Since the energy storage device 4 is not arranged beside the electronic components 3 as in the conventional electronic control device for motor vehicle locks shown in FIG. 1 , but is arranged above the electronic components 3, the area of ​​the circuit board 2 or the base area of ​​the electronic control device 1 is significantly reduced.

[0047] Since the energy storage device 4 is arranged above the electronic components 3, the electronic control device 1 is slightly higher than conventional electronic control devices for motor vehicle locks. Figure 3 However, since the energy storage device 4 is usually designed to be relatively flat, the increase in height is small. Since the base area is reduced, material can also be saved, so that the electronic control device 1 can be manufactured more cost-effectively.

[0048] exist Figure 4 A two-layer structure is shown in FIG. Figure 4 Shows Figure 3 The electronic control device 1 in Figure 3 The sectional view of the cutting line XX is shown. The electronic components 3 are arranged in the first plane A on the circuit board 2. The energy storage device 4 is arranged in the second plane B above the electronic components 3. The planes A and B are respectively formed by vectors in the z direction and vectors in the x direction. Figure 4 This is not shown in the figure due to the two-dimensional illustration. However, it is shown that the level B is arranged above the level A. Therefore, it is shown that the energy storage device 4 is arranged above the electronic component 3.

[0049] The housing 5 comprises a recess 7 and thus forms an integrated retaining device 10. The energy accumulator 4 is inserted into the recess 7. By clamping the energy accumulator between the recess 7 and the housing cover 6, the energy accumulator 4 is fixed in a position-invariable manner together with the housing cover 6. The two-layer structure of the electronic control device 1 for controlling a motor vehicle lock according to the present invention achieves a compact design, because the basic area of ​​the electronic control device 1 is reduced by arranging the energy accumulator 4 above the electronic components 3.

[0050] Advantageously, the energy accumulator 4 and / or the contact unit 8 are fixed in position by clamping, injection molding, gluing, screwing, clipping or coating or impregnation with, for example, epoxy resin, so that the energy accumulator 4 and / or the contact unit 8, which each have a relatively large weight, are firmly fixed and will not break or be damaged in other ways even under high acceleration and / or vibration.

[0051] Figure 51 shows a cross-sectional view of a motor vehicle lock 11 constructed according to the invention in a section through the circuit board 12, the housing 13, the housing cover 14 and the energy accumulators 15, 16. In this embodiment, the energy accumulators 15, 16 are arranged in the second plane CC and the circuit board 12 is arranged in the first plane DD. Here, the energy accumulators 15, 16 are received in an elastomer support 17 in a form-fitting manner, which is formed in the form of ribs in this embodiment. With the help of the ribs 18, line contact can be achieved between the elastomer material 17 and the energy accumulators 15, 16. In order to reliably support or fix the energy accumulators 15, 16, the energy accumulators are fixed between the housing cover 14 and the elastomer material 17. In this embodiment, the elastic support 17 is also received in a form-fitting manner in the recess 19 of the housing 13. Therefore, this embodiment shows the elastic support 1 as an independent component. The energy accumulators 15 and 16 are fixed by pressing the housing cover 14 onto the energy accumulators 15 and 16, and thus the pressing force of the energy accumulators 15 and 16 presses against the elastic bearing 17. It can be clearly seen that the planes CC and DD are spaced apart from each other and the energy accumulators are arranged only in a partial area above the circuit board 12. In this embodiment, the electrical contacts of the energy accumulators 15 and 16 and a part of the circuit board 12 are not shown. The electrical components 20 on the circuit board 12 can be seen, wherein the circuit board 12 also extends below the energy accumulators 15 and 16. In this embodiment, the energy accumulators 15 and 16 are arranged only in a partial area above the circuit board 12.

[0052] Figure 5 A part of a mechanical device 21 of the motor vehicle lock 11 is also shown, wherein the mechanical device 21 is separated from a dry space 23 of the circuit board 12 by a partition wall 22. The energy storage devices 15, 16, the electrical components 20 and the circuit board 12 are located in the dry space of the motor vehicle lock 11, i.e. the mechanical device 21 is arranged in the motor vehicle lock 11 in a sealed manner relative to the electrical components 20, 15, 16 and the elastic bearing 17.
