Description

Technical Field

[0001]

[0001] The present invention relates to an opener device for an automotive door, comprising a drive unit for an opener element, and additionally at least one sensor and a holding element acting on the opener element and / or the automotive door.

[0002]

[0002] For aerodynamic reasons, there is an increasing attempt to design motor vehicles, particularly their automotive doors, without a door handle for opening from the outside. In order to still be able to open the automotive door, an opener device is provided. By means of the opener device, the automotive door is opened substantially after a possible prior question / answer dialogue between the operator wishing to enter the vehicle and the respective motor vehicle and, if applicable, after prior unlocking. This corresponds to the gap between the automotive door and the vehicle body associated therewith.

[0003]

[0003] The gap occurs in order to ensure that the drive unit of the opener element or the sealing force of the door rubber is usually moved to the gap position where the respective automotive door is slightly opened. This usually corresponds to a gap of a few centimeters with respect to the vehicle body, which enables the automotive door to be gripped with one hand through this gap and swung to be fully opened. Thereby, the interior of the motor vehicle becomes accessible.

[0004]

[0004] The opener device for the automotive door is provided with a first sensor assigned to the drive element and capable of distinguishing at least between the automatic opening process and the manual opening process of the automotive door, as described in German Patent Application Publication No. 1020161057601. This is intended to provide weight reduction while providing improved comfort.

[0005]

[0005] According to further prior art according to German Patent Application Publication No. 102018132666, a force measuring device having an associated sensor is accommodated in an opener device so as to be able to detect the movement of a gear carrier. The gear carrier belongs to an electric motor drive unit for an opener element and represents a component of a gear unit arranged between the opener element and the electric motor drive unit.

[0006]

[0006] In the general prior art according to German Patent Application Publication No. 102018132665, an automobile door or an associated door element can be held by adjustment means or by an opener element. For this purpose, a lock lever is provided which can be connected in a form-fitting manner to the automobile body. Thereby, it becomes possible to safely open the automobile door even on an inclined road, since the holding element prevents the automobile door from swinging open without being controlled.

[0007]

[0007] In addition, a sensor is realized, and by using this sensor, it is possible to detect the pulling force exerted by an operator on the automobile door, thereby making it possible to unlock the lock lever. Thereby, the automobile door is released from the body.

[0008]

[0008] The current state of the art is proven in principle in itself. However, for example, when an automobile having an automobile door without a handle is involved in an accident, the current approach reaches its limits. In this case, since the electric motor drive unit of the opener element is usually not operating, in order to open the automobile door, additional separate measures must be taken by the arrival of security personnel. However, the persons concerned may face problems such as the emergency operation handle not being immediately visible or being damaged when they arrive at the automobile. The present invention generally attempts to improve this.

[0009]

[0009] The present invention is based on the technical problem of further developing such an opener device so that possible accidents or collisions can also be brought under control and the door can be easily and quickly opened by the arrival of safety personnel.

[0010]

[0010] To solve this technical problem, a general opener device for an automotive door, in the context of the present invention, is characterized in that a sensor is designed as a collision sensor and, based on a collision signal, an opener element acts on the automotive door and a holding element fixes the automotive door and / or the opener element in a started open position.

[0011]

[0011] First, it should be noted that the term "automotive door" should be widely and generally understood comprehensively within the context of the present teachings of the invention. This includes both automotive side doors and automotive tailgates. Similarly, if applicable, the front hood, automotive sliding doors, loading flaps, etc. This means that according to the present invention, the term "automotive door" does not only include automotive side doors that enable access to automotive occupants inside the vehicle who may be injured. In principle, of course, in the case of a collision, there may be a case where the engine hood has to be opened to extinguish the engine, or a case where the tailgate has to be opened so that some dangerous load can be taken out.

[0012]

[0012] In either way, the relevant collision can be detected first with the help of a sensor designed as a collision sensor. This typically corresponds to a deceleration of the vehicle that exceeds a value of several g (where g is the acceleration due to gravity), typically several tens of g. In any case, an accident or collision can typically be reliably detected using a collision sensor connected to a control unit. The control unit then ensures that safety measures are initiated in the vehicle, such as, for example, the seat belt tensioner is activated and one or more airbags are triggered.

[0013]

[0013] According to the invention, as a result of a collision signal or a plurality of collision signals detected by a sensor or a collision sensor, here, the vehicle door is actuated by an opener element and moved to the initiated open position of the vehicle door. In principle, the initiated open position can be presented during a collision, but is substantially implemented only after a collision. This means that as soon as the deceleration force acting on the vehicle measured by the collision sensor subsides, the associated collision signal is evaluated by the control unit such that the associated vehicle door or some vehicle doors are opened then and thereafter (or can be opened).

[0014]

[0014] The opening of the associated vehicle door can be performed depending on whether the seat is occupied or not. This means, for example, that if only the driver's seat is occupied, the invention is limited to opening only the driver's door. For safety reasons, the general procedure can be such that all of the vehicle doors are opened to enable the arriving security personnel to have complete access to the interior of the vehicle. For example, it can be considered that the driver's door is immovable and the injured driver has to be rescued through the passenger door.

[0015]

[0015] The holding element additionally activated in this context ensures that the vehicle door is fixed in its initiated open position and does not swing uncontrollably and open. Alternatively or additionally, the same applies to the opener element. This can be the case, for example, in the event of a rollover or an accident on a slope, and of course, it must be prevented that any injured person inside the vehicle rolls out and possibly gets further injured.

[0016]

[0016] The overall procedure can be such that the opener element and the retaining element act simultaneously. It is also conceivable that the opener element acts on the automotive door first and then the retaining element fixes the automotive door at the initiated open position. Generally, to enhance functional reliability or avoid any functional problems, the procedure is such that the retaining element is first moved to the position of the retaining element that fixes the automotive door or the opener element, and only then does the opener element move the automotive door to the initiated open position.

[0017]

[0017] The normal procedure is to ensure that the gap corresponding to the open position is several centimeters, for example, 10 mm, 20 mm or more, and substantially up to 50 mm. Since the retaining element usually already assumes the position of the retaining element that fixes the automotive door when the opener element acts, it is necessary that the retaining element can withstand any force exerted by the opener element on the automotive door and thus also on the retaining element. Such a force can be up to approximately 1 kN. Such an opening force exerted by the opener element on the automotive door is often necessary in order to be able to move the automotive door that can be supported against the vehicle body after a collision. In most cases, the corresponding opening force is approximately 0.5 kN to 1 kN, and of course it can be made higher as required.

[0018]

[0018] In any case, both the drive part of the opener element and the retaining element are designed to be able to absorb the aforementioned opening force. At the same time, this ensures that the opening force is sufficient to provide access to the interior of the vehicle even after a collision and in the case of distortion where the automotive door may open relative to the vehicle body.

[0019]

[0019] Generally, the procedure is such that the collision sensor and the drive unit of the opener element, as well as the retaining element, or preferably a separately additionally provided drive unit of the retaining element, are connected to the aforementioned common control unit. This enables the control unit to control the drive unit of the opener element and, if applicable, an additional separate drive unit of the retaining element based on the collision signal emitted by the collision sensor and evaluated by the control unit. As already explained, a typical procedure is that the retaining element first assumes the position of the retaining element that holds or fixes the vehicle door, and only then is the opener element actuated.

[0020]

[0020] In this regard, various basic approaches are conceivable. The drive unit of the opener element can be designed as an electric motor drive unit. This can be useful for normal operation. In addition, an energy storage drive unit that is used only in the event of a collision or immediately after a collision can be provided for the opener element. As an alternative to the energy storage drive unit, a chemically reactive drive unit is also conceivable. According to a preferred embodiment, this can be a pyrotechnic drive unit, i.e., a pyrotechnic drive unit in which a chemical reaction that substantially causes the expansion of a cylinder, which in turn acts on the opener element to open the vehicle door, is triggered therein.

[0021]

[0021] As a principle, alternatively or in addition, electromechanical drive units can also be used for the opener element. Such electromechanical drive units typically act on the opener element without a motor, and in this context, for example, shape memory metals, piezoelectric drive units, etc. are used. The drive units already described can be used individually or in any combination. For example, the energy storage drive unit may be designed as a spring accumulator or may include one or more such spring accumulators. The said energy storage device can be provided with the energy already required in the factory. Then, the available energy in the energy storage device is only used in case of a collision to move the opener element to its open position. In this context, the energy storage device can also be used to move a vehicle door that can be seized or blocked in case of a collision with the body to the open position.

[0022]

[0022] Instead of filling the energy storage drive unit at the factory or realizing the energy storage device or spring accumulator at this point, it is also possible to charge the energy storage device during normal operation via the drive unit of the opener device or opener element at regular or certain predefined intervals. When the spring accumulator is used as the energy storage drive unit or the associated energy storage device, it can be designed such that when the open position is reached, no force is (any longer) exerted on the holding element that is already in its holding or fixed position, and as a result, any damage caused thereby is avoided. In addition, by combining two or more springs, it is possible to realize the said energy storage device or spring accumulator. Here, for example, a strong spring as a component of the energy storage device or spring accumulator can be considered to act on the opener element to such an extent that the vehicle door is almost moved to the open position of the vehicle door or just before that. An additional second, weaker spring can then ensure that the opener element completes the rest of the path of the opener element to the open position.

[0023]

[0023] In this regard, the drive unit of the opener element can also be provided with a separate energy source independent of the vehicle battery. This enables the drive unit of the opener element to ensure that the vehicle door is opened even if the power supply line to the vehicle battery is interrupted in the event of a collision. This separate energy source can be a battery, one or more capacitors, or a combination.

[0024]

[0024] Of course, when on the one hand the electric motor drive unit for normal operation and on the other hand the energy storage drive unit in the event of a collision are realized in parallel, it is also possible to advance both of the aforementioned drive units jointly to act on the opener element and thus on the vehicle door. Such a joint action is also in principle possible outside of and unrelated to a collision, for example when a particularly large force has to be overcome on the vehicle door in order to be able to open it, as is the case, for example, when the vehicle door is frozen. In this case, a force sensor may also be realized in addition to the sensor or the collision sensor, in which case, depending on the signal from the force sensor, the opener element is acted upon by the electric motor drive unit for normal operation and additionally by the energy storage drive unit.

[0025]

[0025] As a rule, the drive unit can also act on the release member of the mechanical energy storage device. This means in this case that the drive unit itself does not act on the opener element. Rather, the release member is actuated via the drive unit such that when the release member is removed or released, the mechanical energy storage device can release the energy stored therein. In the simplest case, the mechanical energy storage device is the spring accumulator already described in detail above. The release member may be designed as a latch that releases the spring accumulator and is actuated by the drive unit. As a rule, the release member or latch can be actuated via the opener element and the drive unit for normal operation, for example, such that the drive unit for normal operation is actuated in the opposite direction beyond a specific end position. In any case, such a release member requires substantially only a small amount of energy from the drive unit for its actuation, so that in this case, the energy source that can be additionally provided to the drive unit can be designed to be particularly simple, small, lightweight, and have a low capacity independent of the vehicle battery.

[0026]

[0026] In a typical case, the opener element and / or the retaining element can be moved to a position that releases the vehicle door by means of an actuating means. The actuating means may be a door handle, in particular an interior door handle. However, alternatively or additionally, an actuating element that is preferably externally accessible can also be realized.

[0027]

[0027] In this way, for example, the retaining element can be actuated via the door handle or the interior door handle. This enables the people inside the vehicle involved in an accident to be secured using the retaining element and to easily open the vehicle door which is in the open position initiated after the collision. Of course, this operating option also takes into account the fact that the child safety lock function is implemented in the rear side doors of the vehicle or that the child safety lock can be engaged. In this case, it has proven to be effective when the actuating means is mechanically coupled to the opener element and / or the retaining element via a push-in and push-out coupling. In the "child safety lock on" position, the coupling is disengaged so that a child in the rear area cannot open the respective vehicle door using the door handle or the interior door handle even after an accident. This requires engaging the coupling so that the associated rear side door of the vehicle can subsequently be opened using the interior door handle as the actuating means.

[0028]

[0028] Actuating elements accessible from the outside can be, for example, an emergency handle. For this purpose, the actuating means can preferably comprise flexible connecting means, for example Bowden cables, via which the actuating means establish the necessary mechanical connection to the retaining element and / or the opener element. In this context, the said actuating element accessible from the outside is marked in the event of a collision, slightly mechanically exposed, or otherwise identified in such a way that arriving security personnel can recognize the said actuating element accessible from the outside and can immediately open the motor vehicle door. All that is necessary for this is that the retaining element is removed from its fixed position in a typical case, or from the position of the retaining element that holds the motor vehicle door via the actuating element accessible from the outside, so that the said motor vehicle door can then be easily swung open manually. This is because the said motor vehicle door is already in the open position of the motor vehicle door after the collision, so that the arriving security personnel can easily grip the corresponding door leaf through the gap between the door leaf and the motor vehicle body and swing it open.

[0029]

[0029] Finally, it has been proven to be effective when the opener element and / or the retaining element engage with the contour of the motor vehicle door. This contour of the said is particularly preferably a lock holder connected to the motor vehicle door. The design is usually such that both the opener element and the retaining element engage with the said lock holder. As a result, since the lock holder functions in the corresponding sense and is used for this purpose, no additional means or additional configuration on the motor vehicle door is clearly necessary.

[0030]

[0030] As a result, an opener device for a motor vehicle door is provided that ensures that in the event of a collision, the motor vehicle door assumes its open position. This makes it particularly easy and intuitive for arriving emergency personnel to gain access to any person inside the vehicle involved in the accident. All that is required is to remove the retaining element that fixes the motor vehicle door in the open position or the initiated open position. This can be done very easily manually through the gap between the motor vehicle door and the motor vehicle body in the initiated open position or the open position assumed by the motor vehicle door.

[0031]

[0031] However, for example, it is also possible that the arriving emergency personnel act on an actuating element accessible from the outside for this purpose, whereby the retaining element is moved from the position where it fixes the motor vehicle door to a position where it releases the motor vehicle door. This means that the motor vehicle door is then immediately accessible and can be easily swung open manually.

[0032]

[0032] In this context, it is also preferable to proceed in such a way that even a bent or jammed motor vehicle door can be substantially opened after a collision. For this purpose, the invention substantially additionally and by way of example uses an energy storage drive unit and / or a chemically reactive drive unit and / or an electromechanical drive unit in addition to the electric motor drive unit for the normal operation (i.e., other than in the event of a collision) of the opener element. The said drive units provide an opening force that significantly exceeds the opening force of the electric motor drive unit for normal operation. For example, an opening force of up to 1 kN or more can be achieved and implemented with such an energy storage drive unit, for example by using a spring accumulator.

[0033]

[0033] This significantly improves the overall safety of any vehicle occupants involved in an accident and greatly facilitates the work of the arriving emergency personnel. In the best scenario, for example, the opener device according to the present invention already ensures that the motor vehicle door is in its open position after a collision, so that no tools or bars are required to pry open one or more motor vehicle doors. These are the main advantages.

[0034]

[0034] The present invention will now be described in more detail with reference to the drawings showing only one exemplary embodiment.

Embodiments for Carrying Out the Invention

[0036]

[0035] The figure shows an opener device for a motor vehicle door 1. In the exemplary embodiment, the motor vehicle door 1 is the front motor vehicle side door 1. However, in general, the motor vehicle door 1 can also be designed as a rear motor vehicle side door, a tailgate, etc., as already explained in the introduction section. For this purpose, the opener device of the motor vehicle door 1 first has a drive part 2 of an opener element 3. In addition, the sensor 4 shown in FIG. 1 is realized, which is a collision sensor 4 according to the present invention. This means that an accident or collision of the associated motor vehicle can be detected with the help of the sensor or the collision sensor 4. This usually corresponds to a deceleration far exceeding 5g.

[0037]

[0036] From FIG. 1, in addition to the drive unit 2 of the opener element 3, within the scope of the exemplary embodiments, and not by way of limitation, a further energy storage drive unit 7 or a chemically reactive drive unit 6 is realized, and using these, it can be seen that the opener element 3 can be operated as an alternative to the drive unit 2 for normal operation, i.e., it can be actuated in the event of a collision. In addition, a release member 8 is also realized in this context and will be described in more detail below.

[0038]

[0037] Particularly important is the retaining element 9 acting on the motor vehicle door 1. It can be seen that the drive unit 2 of the opener element 3 during normal operation, the sensor or collision sensor 4, and also the chemically reactive drive unit 6, or alternatively the energy storage drive unit 7, and the retaining element 9, or a separate drive unit associated with the retaining element 9, are connected to a common control unit 5. In this way, the control unit 5 can be designed such that, as a whole, based on the collision signal from the collision sensor 4, the opener element 3 or the chemically reactive drive unit 6 or the energy storage drive unit 7 can act on the opener element 3 and thus on the motor vehicle door 1 and can operate. In addition, the control unit 5 in the exemplary embodiment ensures that the retaining element 9 fixes the motor vehicle door 1 in the initiated open position.

[0039]

[0038] The drive units 2, 6, 7 can be functionally and conceptually distinguished such that the drive unit 2 for normal operation is hereinafter referred to as the normal operation drive unit 2, while the alternative drive units, i.e., the energy storage drive unit 7 or the chemically reactive drive unit 6, are hereinafter referred to as the collision operation drive units 6, 7. Thus, according to the exemplary embodiment, the collision operation drive units 6, 7 are only used when a collision event is detected using the collision sensor 4. In principle, the combined operation of both the normal operation drive unit 2 and the two collision operation drive units 6, 7 is of course conceivable. However, this is not shown in detail. As already described in detail herein, no further possibility of alternatively or additionally using an electromechanical drive unit as the collision operation drive units 6, 7 is shown either.

[0040]

[0039] In any case, the drive units 2, 6, 7 can be provided with a separate energy source 10 independent of the battery of the motor vehicle. In an exemplary embodiment, this separate energy source 10 may be, but is not limited to, an accumulator or battery, one or more capacitors, etc. In addition, the drive units 2, 6, 7, more specifically the impact operation drive units 6, 7 or the energy storage drive unit 7, can be provided with a release member 8. In this regard, the release member 8 ensures that the energy stored in the mechanical energy storage device 11 is released. For this purpose, a small amount of electrical energy is sufficient to operate the release member 8.

[0041]

[0040] Only the actuating means 12, 13 are shown, by means of which the opener element 3 and / or the retaining element 9 can act on the motor vehicle door 1 and move it to a position where the motor vehicle door 1 is released. According to an exemplary embodiment, the actuating means 12, 13 are the door handle or the interior door handle 12. In the example shown, the retaining element 9 can move from the position of the retaining element that fixes the motor vehicle door 1 to the position of the retaining element that releases the motor vehicle door 1 via the interior door handle 12. For this purpose, the retaining element 9 is simply pivoted with respect to the lock holder 15, as can be seen from FIG. 5. In fact, in the position of the retaining element that fixes the motor vehicle door 1, the retaining element 9 engages between the two brackets of the lock holder 15, ensuring that the opened motor vehicle door 1 cannot swing open in an uncontrolled manner.

[0042]

[0041] The same function is executed by an additionally shown actuating element 13 that is accessible from the outside. For this purpose, the actuating element 13 may preferably be connected to the holding element 9 by means of a flexible connecting means 14. The flexible connecting means 14 according to an exemplary embodiment is a Bowden cable. Thus, when the actuating element 13 accessible from the outside is actuated, the holding element 9 is moved again from the position of the holding element that fixes the motor vehicle door 1 to the position of the holding element that releases the motor vehicle door 1. As a result, the motor vehicle door 1 can be easily swung open as a whole, for example, by a safety official arriving after the described collision gripping the motor vehicle door 1 through the gap with the motor vehicle body in the open position and thereby swinging and opening the motor vehicle door 1.

[0043]

[0042] The further possibility that the actuating means 12, 13, in particular the inner door handle 12, are mechanically coupled to the opener element 3 or the holding element 9 via an engagable and disengageable coupling is not explicitly shown. This makes it possible, as before and without modification, to implement and implement a child safety lock function on a rear motor vehicle side door (not shown here). When the associated child safety lock unit is in its "child safety lock on" position, the disengaged coupling in this case ensures that the holding element 9 cannot pivot via the inner door handle 12, and as a result, even after a collision, the position of the holding element that fixes the motor vehicle door 1 is held in a way that does not change. This is released only when the holding element 9 is moved, for example, from the outside from the position of the holding element that fixes the motor vehicle door 1 to the release position, or when the aforementioned coupling is engaged. This is because in this case the inner door handle 12 is mechanically coupled to the holding element 9, and as a result, the action on the inner door handle 12 ensures that the holding element 9 is moved from the position of the holding element that fixes the motor vehicle door 1 to the position that releases the motor vehicle door 1.

[0044]

[0043] The operating mode is as follows. When the motor vehicle is moving in normal operation, the opener element 3 is actuated by the normal operation drive unit 2 following the question / answer dialog and unlocking described in the description, and, if applicable, the electric motor release of the motor vehicle lock not shown here. For this purpose, the normal operation drive unit 2 ensures that the motor vehicle door 1 is moved to the open position of the motor vehicle door relative to the motor vehicle body, which is only shown in FIG. 1. In this open position, since the motor vehicle door 1 presents a gap of several centimeters relative to the motor vehicle body, the operator attempting to gain access can grip and swing open the motor vehicle door 1 through the gap.

[0045]

[0044] When a collision occurs, this is usually associated with the fact that the normal operation drive unit 2 is electrically disconnected from the battery of the motor vehicle and thus does not substantially function (or no longer functions). In this case, the energy source 10 independent of the vehicle battery ensures that the collision operation drive units 6, 7 can continue to operate and move the motor vehicle door 1 to its initiated open position or open position. This is usually done after a collision in an exemplary embodiment. This means that first, the collision sensor 4 records the collision and reports it to the control unit 5. After the collision or the corresponding deceleration has subsided, the control unit 5 evaluates the corresponding collision signal of the collision sensor 4 and ensures that the collision operation drive units 6, 7 are activated with the help of the energy source 10 independent of the vehicle battery.

[0046]

[0045] Here, the collision operation drive units 6, 7 ensure that after a collision, the motor vehicle door 1 according to an exemplary embodiment is moved to the open position using the energy storage drive unit 7, or by using the chemically reactive drive unit 6, or by both. The collision operation drive units 6, 7 can exert a high opening force, for example, of 1 kN or more, on the opener element 3 or the motor vehicle door 1. In this way, in typical cases and after a collision, the vehicle door can be opened even if it becomes immovable or jammed.

[0047]

[0046] Previously, the retaining element 9 has been moved to the position of the retaining element that fixes the vehicle door 1. As a result, after a collision event, in an exemplary embodiment, the collision operation drive units 6, 7 cause the vehicle door 1 to be moved not only to the initially opened position of the vehicle door using the opener element 3, but also ensure that the vehicle door 1, more specifically the lock holder 15, moves relative to the retaining element 9. In order to keep the forces observed at this point low, according to the individual figures of FIG. 4 in combination with the energy storage drive unit 7 or the mechanical energy storage device 11 implemented at this point, the energy storage device 11 can be advanced to act on the vehicle door 1 only until the open position is reached, as a result of which an impact on the retaining element 9 is prevented or at least the impact is reduced. For this purpose, in a variant not shown, it is conceivable to design the mechanical energy storage device in two parts, a strong spring and a weak spring.

[0048]

[0047] In this connection, the strong spring ensures that the vehicle door 1 is opened by acting on the opener element 3 until it reaches approximately the open position. Then, the weak spring completes the remaining path to reach the open position and specifically ensures that the lock holder 15 moves relative to the retaining element 9. In either case, the lock holder 15 functions substantially as the contour of the vehicle door 1 that interacts with the opener element 3 and the retaining element 9 according to the exemplary embodiment.

[0049]

[0048] This is best understood from the individual figures of FIG. 5. Here, it is clear that the opener element 3 as a whole is actuated via a lever drive using the electric motor drive unit 2 and moves relative to the lock holder 15. In the context of the exemplary embodiment, as a result of the action of the electric motor drive unit 2, the opener element 3 adjusts the lock holder 15 "to the left", which corresponds to the vehicle door 1 being opened "to the right" relative to the vehicle body until the open position is reached.
