Abstract
Description
Technical Field
[0001] This invention relates to a cover / hatch cover lock or flap lock for a motor vehicle, the lock comprising a locking mechanism having a rotating locking fork and at least one pawl, a lock retainer / bolt interacting with the locking mechanism, a release lever, wherein the locked locking mechanism can be unlocked by means of the release lever, and the lock retainer can be moved from a locked position to a supported position after a first actuation operation, and the lock retainer can be moved to a released position after a second actuation operation of the release lever; and a closing actuator, wherein the locking mechanism can be moved from a supported position to a main locked position by means of the closing actuator, and at least one position of the rotating locking fork can be detected by means of a switching device. Background Technology
[0002] Locks or locking systems for motor vehicles are used in situations where doors, flaps, or movable parts must be kept in the vehicle to ensure safe driving. Even though locking systems are primarily used to keep movable parts in their closed positions, comfort features are increasingly emphasized today. In this context, for flaps, ensuring secure closure and ease of opening are paramount.
[0003] In this configuration, the hood or flap can be closed with a seal to provide, for example, a waterproof or dustproof seal. In this case, a seal means that when the lock is closed, counter-pressure resists the locking mechanism, which acts as a fixing element.
[0004] Preferably, and typically, for hood / engine cover or flap / hinge-type panels, a lock retainer is fastened to the hood or flap, and then interacts with the vehicle lock. The lock retainer generally interacts with the locking mechanism of the associated vehicle door lock. The lock retainer and the vehicle door lock together define the vehicle door locking device. By combining with the locking mechanism in the vehicle lock, the lock retainer ensures a safe and reliable closure. In principle, this can also be reversed.
[0005] Because of its primary closing function, which combines the lock holder with the locking mechanism in the vehicle lock, this is a particularly safety-related component, and especially in the event of an accident, it will bear specific loads. In fact, the protection of vehicle occupants in the event of an accident largely depends on the reliability of the lock retainer and the locking mechanism interacting with it in absorbing the forces acting upon it. This is because, in such cases, it is crucial that movable components on the vehicle remain closed, or that covers or flaps remain closed, so that safety devices installed in or on the vehicle (such as brake assist devices, side airbags, side impact protection devices, etc.) can function as intended.
[0006] The locking mechanism included in a vehicle lock has a pre-locked position or a holding, supporting, or latching position, as well as a main locking position. In the case of a flap lock or hood lock, a two-stroke / two-actuation actuation is provided. By means of the first stroke, for example via Bowden cable or by means of an electric actuator acting on the vehicle lock, the lock retainer moves from the main locking position (hood closed) to the pre-locked, supporting, or latching position. This ensures that the hood will not fully open and endanger the driver or passengers in the event of accidental actuation of the Bowden cable. The hood or hood will only be fully released after a second pull of the Bowden cable or electric actuator or manual actuation lever.
[0007] The aforementioned type of front flap lock is described in DE 296 00 386 U1. The front flap lock interacts with a closing lever. The front flap lock is typically located at the front of a motor vehicle and interacts with the closing lever of the front flap. The closing lever is pivotally mounted on the front flap and can pivot from a normal position to an averted position against the restoring force of the closing lever spring. This can be achieved by means of an actuating handle, which can be actuated by the user when the closing lever is in the pre-locked position. The closing lever then pivots away from its path of motion and can pivot about the end of the catch hook. During the closing of the closure, the closing lever, especially the rib forming the end of the closing lever, slides along the control side of the catch hook, which, in the prior art, is fixedly connected to the lock housing. The catch hook passes the end of the control side and is then moved rearward by a tensioned catch hook spring, so that it is in a rear-engaged position relative to the locking side. As the closing lever moves further, it enters the locking jaws of a rotary locking fork, which rotates and is secured in the locked position by a pawl during further movement of the closing lever.
[0008] A front flap / flip lock is known from DE 10 2010 061 518 A1, comprising a latch assigned to the lock housing for capturing a closing lever. The latch includes a control side and a locking side located in the movement path of the closing lever, which can deviate from its movement path. Specifically, when the front flap is closed, the closing lever initially slides on the control ramp of the latch, which is fixed in a locked position relative to the lock housing. After passing through, the end of the latch enters a pre-locked position behind the locking side and is held in a locked position by a locking port of a pawl—in which the closing lever enters the locking port in the open position of the rotary fork after the front flap has moved further in the closing direction. The latch is fixedly connected to the rotary fork, and the rotary fork is prevented from pivoting to its open position by a spring-loaded pop-out arm. When the closing lever enters the locking port, the pivoting preventer is released due to the movement of the pop-out arm.
[0009] To enable the transfer of the lock from the support position to the master locking position with electric motor assistance, for example to increase operational comfort in motor vehicles, it is known from the undisclosed document DE 10 2021 119 635 A1 that the cover lock is transferred from the support position to the master locking position by a closing actuator. In this case, a switching device can be used to detect the position of the rotating lock fork in order to control the closing actuator. Summary of the Invention
[0010] The purpose of this invention is to improve the control technology of the aforementioned front-flip lock. Furthermore, the purpose of this invention is to design the lock in a way that is generally simpler in structure and lower in cost.
[0011] This objective is achieved by the features of independent claim 1. Advantageous embodiments of the invention are described in the dependent claims. It should be noted that the embodiments described below are not limiting; rather, any variations of the features described in the specification and dependent claims may be implemented.
[0012] According to claim 1, the object of the present invention is achieved by providing a cover lock for a motor vehicle, the cover lock comprising a locking mechanism having a rotating locking fork and at least one pawl, a lock retainer interacting with the locking mechanism, a release lever, and a closing actuator, wherein the locked locking mechanism can be unlocked by means of the release lever, the lock retainer can be transferred from a locked position to a supported position after a first actuation operation, and the lock retainer can be moved to a released position after a second actuation operation of the release lever, the locking mechanism can be moved from the supported position to a main locking position by means of the closing actuator, at least one position of the rotating locking fork can be detected by means of a switching device, and at least one additional switching device is provided for detecting the pawl position. As a result of the lock design according to the invention, a lock for a motor vehicle, particularly a cover lock, can now be provided, wherein the transfer of the rotating locking fork from the supported position to the main locking position is optimized in terms of control technology. Specifically, the combination of rotating locking fork position detection and pawl position detection can be used to achieve a safe transfer of the cover to the closed position, i.e., the main locking position. In this case, detecting the pawl position allows the closing operation to be initiated in a targeted and clearly controlled manner. The closing operation can only be initiated when the pawl reliably detects that the rotary locking fork is in the supported position, i.e., the pre-locked position. Therefore, further securing of the specified closure can be provided. This is particularly advantageous because the closing of the cover and the transfer to the fully closed position are performed in a motor-assisted manner. If the pawl has not fully engaged in the rotary locking fork when reaching the supported position, i.e., the pre-locked position, it can be identified that, for example, the cover cannot be closed using the motor. This is advantageous because, for example, there might be an object between the cover and the vehicle body, which would prevent full access to the supported position. Therefore, the securing device for controlling the closure can be provided by another switching device.
[0013] As described above, the present invention relates not only to cover locks, but also particularly to hinged panels (flip-ups) or components that are movably arranged in a similar manner on a motor vehicle. However, preferably, the present invention relates to a cover lock for a motor vehicle. The cover lock particularly relates to cases where the cover is located in the front area of the motor vehicle. Therefore, the cover can also be referred to as an engine hood / engine cover. However, it is also conceivable that a trunk is located below the cover or flip-up, or that an electric motor for the motor vehicle or a controller driven by the electric motor is located there. In this case, the cover may be provided with a peripheral seal to, for example, protect luggage from moisture intrusion. The cover must then be pulled closed against this seal, moving from a supported position to a main locking position or a closed position. For this purpose, the closing actuator must overcome the resistance of the seal, thus requiring a significant force to be applied in the lock to securely close and reach the main locking position.
[0014] The locking mechanism in motor vehicle locks is well-known, consisting of a rotary fork and at least one pawl. In the claimed motor vehicle lock, a rotary fork is provided that holds the lock retainer in a closed master locking position and can also be in a support position where the hood is held partially open. This is particularly important because the hood must be held in the support position in the event of accidental opening. A single actuation of the locking mechanism to fully open the hood poses a risk of immediate full opening, potentially leading to an accident during driving. Therefore, the claimed hood lock provides a two-step opening process. In other words, the locking mechanism is unlocked twice. First, the master locking position is unlocked, and the rotary fork is moved to the support or pre-locked position, where the pawl re-enters the rotary fork and secures / locks it. Only during the second unlocking process, after the pawl movement, is the rotary fork released or the lock retainer released, leaving the rotary fork in the open position. The hood can then be opened manually and / or with spring assistance.
[0015] When the open hood is closed, the hood is secured by the rotary locking fork, or more precisely, the locking retainer engages with the rotary locking fork, and due to the weight of the hood, the rotary locking fork reaches the supported or pre-locked position of the locking mechanism. In the supported position, the pawl engages the rotary locking fork, thus firmly holding the hood in place. The rotary locking fork is monitored by means of a microswitch or switching device, thereby allowing the detection of the supported position and / or the main locking position. According to the invention, the locking mechanism has an additional switching device by which the position of the pawl can be detected. The locking mechanism can only be accurately determined to be in the supported or pre-locked position after the pawl is fully engaged in the pre-locked position. The closing actuator can then transfer the rotary locking fork from the pre-locked position to the main locking position. Therefore, the hood can be transferred to the main locking position, i.e., the closed position, a transfer that is technically safe.
[0016] In a later part of the invention, a dual-arm pawl is provided, capable of achieving a main locking position by means of a first arm and a pre-locking position in the locking mechanism by means of a second arm. The dual-arm design of the pawl is achieved such that the pawl is mounted approximately in a central position, allowing pivoting movements in different directions to lock the pawl into the rotary fork. In this case, after the locking mechanism is unlocked, that is, after the pawl is removed from the locking position of the rotary fork, the first arm engages with the main locking portion of the rotary fork with a first locking profile, and the pawl directly enters the range of motion of the rotary fork, thereby ensuring a secure engagement in the pre-locking position. Therefore, unlocking the locking mechanism from the main locking position directly causes the pawl to lock into the second locking profile on the rotary fork. If the pawl is subsequently released by a release lever, the pawl re-enters the engagement area with the rotary fork in a spring-preloaded manner. There, the pawl again locks into the pre-locking profile of the rotary fork, thereby securing the pre-locking or support position of the cover or flap. In the supported position, the lock retainer remains engaged with the rotary lock fork, thus preventing accidental full opening of the cover. In this position, reliable locking of the locking mechanism is achieved by moving / driving the pawl back and forth. The rotary lock fork is only fully released after the pawl is actuated a second time by the release lever, thereby allowing the rotary lock fork to enter the open position and releasing the lock retainer.
[0017] In another variation of the invention, the pawl can be electrically actuated, particularly by means of a release lever. To improve vehicle comfort, the hood can be opened electrically. For this purpose, other safety features can also be achieved, for example, that to fully open the hood, the electric actuator must be actuated twice: first, to move the hood from the main locking position to the pre-locked position, and then, to move the hood from the pre-locked or supported position to the released position. In this case, the electric actuation of the release lever allows for comfortable unlocking without manual intervention, such as when a release hook is required. In this case, the release lever can be moved / driven by an electric motor and a corresponding mechanism. Preferably, the release lever actuates the pawl such that, for example, the release lever is movable or pivotable.
[0018] Advantageously, the pawl position can be indirectly determined or detected via a release lever, which can constitute another design variation of the invention. The release lever is preferably pivotally arranged in the vehicle lock and is pivotally movable via a release actuator, preferably a linear linkage. When the release lever moves, the pawl moves and the locking mechanism can be unlocked. To reliably detect the pre-locked position, a switching device is provided, which can be facilitated to engage with the release lever such that the switching device is actuated only when the pawl is fully engaged in the pre-locked position. In other words, the support position or pre-locked position is detected by a pawl switch. For this purpose, the release lever can have a control profile, for example, that can be facilitated to engage with the switching device, preferably a microswitch.
[0019] If the position of the rotary fork can be detected by means of a drive rod, another design variation of the invention arises. The drive rod can be arranged in the vehicle lock such that it contacts the rotary fork. Specifically, in the main locking position, the drive rod rests against the rotary fork in a spring-preloaded manner and maintains its resting position. The drive rod only reaches the position where it engages with the pawl when the rotary fork is released from the pre-locked position to the open position. Therefore, the rotary fork controls the position of the drive rod, thereby enabling the pawl to be positioned in the released position. In other words, when the rotary fork has reached its open position, the drive rod keeps the pawl disengaged. In the open position, the pawl therefore cannot engage in the rotary fork. In the open position of the rotary fork, the hood can be lifted and opened. Therefore, during the opening of the hood or flap, the drive rod serves to fix the pawl in the released position. For this purpose, the drive rod is pivotally and spring-preloaded in the vehicle lock and preferably rests against the outer surface of the rotary fork. Therefore, the drive rod can also be referred to as a safety rod for positioning the pawl.
[0020] In another design variation of the invention, the position of the rotary locking fork can be detected by means of a control lever. In other words, the switching device does not rest directly on the rotary locking fork, but is instead equipped with a control lever that engages with and can move via the rotary locking fork. Therefore, the control lever functions to detect the position of the rotary locking fork, and can thus be used to control the closing actuator. Consequently, the position of the cover lock can be determined very precisely, allowing for reliable opening and closing or pulling of the cover lock.
[0021] It is also advantageous if the control lever can be facilitated to engage with a profile portion, particularly a pin, on the rotary lock fork. The control lever is spring-preloaded in the vehicle lock and received within it in a preloaded manner in the direction of the rotary lock fork. Preferably, the control lever is movable about a pivot axis, i.e., the control lever is pivotally received within the vehicle lock. In this case, the control lever abuts against the profile portion of the rotary lock fork, thereby allowing reliable detection, particularly direct detection, of the rotary lock fork's position. This profile portion can be formed, for example, by a cover on the rotary lock fork, particularly a plastic cover, or, as described in another embodiment, by a pin arranged on the rotary lock fork. The profile portion or pin moves the control lever, thereby directly engaging it, enabling reliable detection of the rotary lock fork's position.
[0022] Another design variation of the invention arises if the control lever can be facilitated to engage with the switching devices, preferably two switching devices. The control lever interacts with the switching devices such that the control lever operates via the movement of the rotary locking fork, and the control lever actuates the switching devices. In this case, the switching device can be a microswitch, but it can also be designed as, for example, a non-contact sensor, such as a Hall sensor. The switching device is preferably a microswitch. In this case, the control lever interacts with the switching devices in such a way that a profile formed on the control lever engages with the switching device, or for example, a magnet is provided on the control lever that interacts with the non-contact sensor. If two switching devices that can be facilitated to engage with the control lever are arranged in the vehicle, targeted and explicit control of the closure actuator can be achieved. In the main locking position of the rotary locking fork, both switching devices are released, i.e., the switching devices are in an inactive state and released by the control lever. When the pre-locking position is reached, the first switching device is actuated, thereby initiating the closure operation. When the rotary locking fork is fully released by the pawl, that is, when the rotary locking fork reaches the open position, the second switching device will also be actuated, so that the controller can receive a clear signal indicating that the engine hood is in the open position. The combination of the two switching devices allows the position of the rotary locking fork to be clearly inferred, thereby reliably detecting the pre-locked or supported position and the main locking position of the rotary locking fork.
[0023] In an advantageous improvement of the invention, the profile on the rotary locking fork can be facilitated to engage with the closing lever. Therefore, the profile or pin on the rotary locking fork has a dual function. First, the profile or pin controls the control lever, and simultaneously, the pin or profile can serve as an engagement device for the closing actuator. For this purpose, the closing lever directly engages with the profile or pin, moving the rotary locking fork from a pre-locked or supported position to the main locking or closed position.
[0024] Another variation of the invention arises when the closing lever can be guided within a reinforcing plate of the vehicle lock. The vehicle lock has a lock housing that at least supports the shaft of the locking mechanism components. Under extreme loads, such as in the event of an accident, the locking mechanism must be able to absorb significant forces. For this purpose, the lock base plate or lock housing is made of steel, and the shaft of the locking mechanism components, as well as the locking mechanism components themselves, are made of metal or steel. The reinforcing plate can support the locking mechanism components and / or the closing actuator and / or the locator lever, or attach them to said shaft. In other words, the reinforcing plate serves to strengthen the vehicle lock and acts as a support for movable parts within the vehicle lock. Advantageously, the reinforcing plate serves as additional support and reinforcement in the vehicle lock, while also acting as a guide for the closing lever. As mentioned above, the closing lever sometimes must transmit significant forces, i.e., when the cover must be closed against the peripheral seal. In particular, it is important to ensure a secure engagement between the closing lever and the rotating lock fork. The guide in the reinforcing plate functions as a guide profile for the closing lever. The guide in the reinforcing plate can be provided, for example, by a pin / bolt on the closing rod, which can be guided in a groove in the reinforcing plate. Of course, the opposite design can also be achieved, for example, with a pin disposed on the reinforcing plate, which functions as a guide for the closing rod.
[0025] It is also advantageous if the release lever and control lever are pivotally housed on the electrical component carrier. Both the release lever and control lever are components that transmit only small forces. Preferably, the release lever and control lever are made of plastic. These two levers—the release lever and control lever—interact with the switching device by means of their control profiles, and the switching device is preferably directly housed and held on the electrical component carrier. This reduces the number of required components and simplifies the overall design of the vehicle lock. If the electrical component carrier also provides a support point for the release lever and control lever, the structural design can be further simplified, allowing the lock to be constructed more cost-effectively overall. Of course, it is also conceivable to mount only one lever on the electrical component carrier and house the second lever in the vehicle lock housing. However, in this case, the housing of the microswitch and lever can form an advantageous design variation that achieves the number of components required for a reliable design of the vehicle lock in terms of control technology. Attached Figure Description
[0026] The present invention will now be explained in more detail with reference to the accompanying drawings, based on preferred exemplary embodiments. However, it should be noted that these embodiments are not intended to limit the invention, but rather to present only one implementation. The various features shown may be implemented individually or in combination with other features of the specification and claims.
[0027] In the attached diagram: Figure 1A side view of a cover lock designed according to the present invention in the main locking position is shown; Figure 2 It shows according to Figure 1 Detailed view of arrow II, control lever shown in sectional view, and Figure 3 It shows according to Figure 1 The rear view of the cover lock shown is a view of the electrical component carrier. Detailed Implementation
[0028] Figure 1 A plan view of the locking mechanism 3 of a motor vehicle lock 1 is shown, which includes a rotary locking fork 3 and a pawl 4. The cover lock 1 is shown in the main locking position, in which the lock retainer 5 is held by the rotary locking fork 3, so that the cover is closed in principle. The lock also mainly includes a lock housing 6, a closing actuator 7, an electrical component carrier 8, a control lever 9, a release lever 10, a transmission lever 11, a positioner 12, and a spring element 13.
[0029] The cover lock 1 is shown in the main locking position, with the pawl 4 abutting against the main locking portion 14 of the rotary fork 3, or the pawl 4 engaged with the rotary fork 3. In this main locking position, the control lever 9 is preloaded by the spring element 15 in the opposite direction to the profile 16 on the rotary fork 3. In this embodiment, the profile 16 takes the form of a bolt / pin on the rotary fork 3. The release lever 10 interacts with the rotary fork 3, particularly the guide pin 18, and interacts with the pawl 4 via the guide 17. The release lever 10 is pivotally housed in the electrical component carrier 8 via the shaft 19 and can be moved counterclockwise by a motor. To move the release lever 10, the drive element 20 engages with the extension 21 of the pawl 4 and moves the release lever 10 counterclockwise. The drive element 20 can be driven, for example, via a linear motor, so that pivoting motion can be introduced into the pawl.
[0030] The positioner 12 rests against the lock retainer / bolt 5 in a preloaded manner by the tension spring 13, such that force acts on the lock retainer 5 in the opening direction of the rotating lock fork. For this purpose, the spring 13 is preferably in the form of a tension coil spring. The spring 13 is fixed to the lock housing 6 at one end, while at the other end, the coil spring engages in the positioner.
[0031] The closing actuator 7 is shown in a non-actuated state, i.e., the closing lever 22 is disengaged from the profile 16. To guide the closing lever 22, a guide pin 23 can be guided in a reinforcing plate (not shown). The closing actuator 7 also includes a drive lever 23, which is pivotally housed in the lock housing via a shaft 24. The closing lever 22 can be actuated by an electric actuator, particularly a motor-actuated Bowden cable 24. For this purpose, the Bowden cable moves in the direction of arrow P and pivots / oscillates the drive lever 23, allowing the closing lever 22 to engage with the pin 16 on the rotary lock fork 3.
[0032] To further explain the control-related design of the cover lock 1, the cover lock 1 has three microswitches 25, 26, and 27. In the shown master locking position, all microswitches 25, 26, and 27 are not actuated, thus the precise positions of the pawl 4 and the rotary locking fork 3 can be detected. To actuate the microswitches 25, 26, and 27, the release lever 10 and the control lever 9 can pivot about axes 19 and 28, respectively. The release lever 10 is preferably moved / driven by the guide pin 18, while the control lever 9 follows the movement of the rotary locking fork 3 via the support leg spring 15.
[0033] Figure 2 A portion of the electrical component carrier 8 is shown, in which the control lever 9 is partially cut open to reveal the positions of the microswitches 26 and 27 beneath it. Figure 1 As shown, neither of the two microswitches was activated.
[0034] Figure 3 The rear view of the cover lock 1, viewed from the perspective of the electrical component carrier 8, is now shown, without the lock housing 6. The electrical component carrier 8 includes conductor lines 29 and a plug 30. The electrical component carrier 8 is shown transparently, allowing the microswitches 25, 26, and 27 to be seen, and explaining the interaction between the microswitches 25, 26, and 27 and the control lever 9 and release lever 10. Control profiles 31 and 32 are shown on the control lever 9 and release lever 10, respectively. The control profile 32 is arranged on the release lever 10 such that movement of the release lever 10 in the direction of arrow P1 actuates the microswitch 25. If the plastic-like extension 21 on the metal pawl 4 is actuated, the release lever 10 pivots in the direction of arrow P1, and the control profile 32 engages with the microswitch 25. The control profile 32 then actuates the microswitch, allowing a clear signal related to the position of the pawl 4 to be detected. If the rotating locking fork 3 is released by the pawl 4, the control lever 9 also moves counterclockwise, specifically in the direction of arrow P2. The movement of the control lever 9 in the direction of arrow P2 first—specifically through the control profile 31—causes the micro switch 26 to be actuated, thereby identifying or detecting the support position or pre-locking position of the rotary locking fork 3.
[0035] If pawl 4 is now actuated a second time, the rotary fork moves from the pre-locked or supported position to the open position, and the control lever follows the movement of the rotary fork. The control lever moves further in the direction of arrow P2, causing the micro switch 27 to also engage with the control profile 31. The second micro switch 27 is now also actuated, and the precise position of the rotary fork can be detected. In the fully open position of the rotary fork 3, pawl 4 is also kept disengaged from the rotary fork 3 by means of the drive rod 11, the profile 33 of the drive rod 11 engaging with the locking surface 34 on the plastic cover 21 of the pawl 4. For this purpose, the drive rod 11 is preloaded with spring force against the rotary fork 3 by means of the spring element 35. When the rotary fork 3 is closed, the rotary fork 3 disengages the drive rod 11 from the locking profile 34 again, allowing pawl 4 to re-enter the rotary fork 3. Then, the microswitches 25, 26, and 27 are actuated in reverse order, so that the locked position, pre-locked or supported position, and main locked (position) can be detected again and sent to the higher-level controller 36 via the electrical component carrier 8 and plug element 30. When the pre-locked position is reached during the closing process, the closing actuator 7 can then be actuated, and the rotating locking fork 3 can be transferred from the supported position or pre-locked position to the main locked position.
[0036] By means of the interaction between microswitches 25, 26, 27 and the rotatable mounting of control lever 9 and release lever 10, the precise allocation of the position of locking mechanism 2 can be detected, thereby enabling the safe closing and opening of cover lock 1.
