The present application claims the benefit of German Patent Application No. 10 2022 131 428.6, filed Nov. 28, 2022, titled “Operating Mechanism for Operating Vehicle Doors,” the contents of which are hereby incorporated by reference.
In particular in the automotive industry, doors and flaps are increasingly no longer only opened or closed (locked and unlocked) manually, i.e., mechanically. Rather, the opening or closing movements are performed more frequently automatically, in particular electrically. For example, an electric motor is used here, which, when desired, drives a mechanism for opening or closing (locking and unlocking) the doors and flaps. In order to generate a signal for opening or closing (locking and unlocking) to such electric drives or the associated control devices, a switch can be provided, which generates the desired signal by an actuation of the user. Such switches can be configured as push-buttons, which, when pressed in by the user, generate the aforementioned signal.
In order to not be reliant on the opening or closing of the doors by the electric drive, it is known to provide a mechanical (manual) emergency release. This allows the user to open the doors or flaps manually. Such mechanical actuating elements, such as conventional interior or exterior door handles, are often provided separately from the push-buttons configured as signal transmitters. Not only does this require additional design space for the mechanical variant, but it also results in a non-uniform overall image in which modern electrical push-buttons are connected to traditional mechanical levers.
For the above-mentioned reasons, the problem addressed by the present disclosure is to specify an actuating mechanism for actuating vehicle doors, which enables an electrical as well as manual actuating function and can be arranged even in the smallest possible space. The new actuating mechanism is intended to generate, in a simple manner, haptic feedback, by way of which the user can feel the actuation of the electrical signal transmitter or the actuation of the emergency release.
The present disclosure relates generally to an actuating mechanism, substantially as illustrated by and described in connection with at least one of the figures, as set forth more completely in the claims.
The foregoing and other objects, features, and advantages of the devices, systems, and methods described herein will be apparent from the following description of particular examples thereof, as illustrated in the accompanying figures; where like or similar reference numbers refer to like or similar structures. The figures are not necessarily to scale, emphasis instead being placed upon illustrating the principles of the devices, systems, and methods described herein.
References to items in the singular should be understood to include items in the plural, and vice versa, unless explicitly stated otherwise or clear from the text. Grammatical conjunctions are intended to express any and all disjunctive and conjunctive combinations of conjoined clauses, sentences, words, and the like, unless otherwise stated or clear from the context. Recitation of ranges of values herein are not intended to be limiting, referring instead individually to any and all values falling within and/or including the range, unless otherwise indicated herein, and each separate value within such a range is incorporated into the specification as if it were individually recited herein. In the following description, it is understood that terms such as “first,” “second,” “top,” “bottom,” “side,” “front,” “back,” and the like are words of convenience and are not to be construed as limiting terms. For example, while in some examples a first side is located adjacent or near a second side, the terms “first side” and “second side” do not imply any specific order in which the sides are ordered.
The terms “about,” “approximately,” “substantially,” or the like, when accompanying a numerical value, are to be construed as indicating a deviation as would be appreciated by one of ordinary skill in the art to operate satisfactorily for an intended purpose. Ranges of values and/or numeric values are provided herein as examples only, and do not constitute a limitation on the scope of the disclosure. The use of any and all examples, or exemplary language (“e.g.,” “such as,” or the like) provided herein, is intended merely to better illuminate the disclosed examples and does not pose a limitation on the scope of the disclosure. The terms “e.g.,” and “for example” set off lists of one or more non-limiting examples, instances, or illustrations. No language in the specification should be construed as indicating any unclaimed element as essential to the practice of the disclosed examples.
The term “and/or” means any one or more of the items in the list joined by “and/or.” As an example, “x and/or y” means any element of the three-element set {(x), (y), (x, y)}. In other words, “x and/or y” means “one or both of x and y”. As another example, “x, y, and/or z” means any element of the seven-element set {(x), (y), (z), (x, y), (x, z), (y, z), (x, y, z)}. In other words, “x, y, and/or z” means “one or more of x, y, and z.”
The present disclosure relates to an actuating mechanism for actuating vehicle doors, in particular for opening vehicle doors. The present disclosure further relates to a vehicle having an actuating mechanism for actuating vehicle doors.
Accordingly, the disclosure relates to an actuating mechanism for actuating, in particular unlocking and opening, vehicle doors, wherein the actuating mechanism comprises the following: an actuator, in particular with a handle, for opening vehicle doors; a kinematics for transmitting a movement of the actuator to a signal transmitter, wherein the kinematics comprises a cam disk; an elastic biasing element biased against the cam disk, wherein the cam disk cooperates with the biasing element in order to define a first force threshold for a first rotation of the cam disk as well as a second, higher force threshold for a second, downstream rotation of the cam disk.
With the new actuating mechanism, haptic feedback is generated by two different force thresholds. Firstly, when actuating the actuator, the user immediately feels the first force threshold, which must be overcome in order to move the actuator and thus the kinematics. The first movement results in a first rotation of the cam disk. This first rotation of the cam disk can, for example, actuate an electrical signal transmitter (e.g., a microswitch). As soon as the actuator is actuated, i.e., pressed or pulled, after the first rotation, a second force threshold is felt by the user. This force threshold is preferably higher than the first force threshold and can thus be perceived by the user as a stop, in particular. However, if the user continues to move the actuator even after the second force threshold, i.e., the perceived stop, has been felt, a mechanical emergency release can be activated as soon as the second force threshold has been overcome.
According to the aforementioned embodiment, with a single biasing element as well as a simple cam disk, it is possible to provide an actuating mechanism with two different functionalities, namely an electrical unlocking as well as a mechanical emergency release.
According to a further embodiment, the cam disk comprises a second step, which is configured to deform, in particular to compress, the biasing element by a first length before the first rotation is released, and preferably a second step, which is configured to deform, in particular to compress, the biasing element by a second length before the second rotation is released. The second length can be greater than the second length. Accordingly, it is achieved in a very straightforward manner that the second force threshold is higher than the first force threshold. In particular, the cam disk need only have a particular design with two consecutive shoulders or ledges. The second shoulder can be formed wider than the first shoulder.
According to a further embodiment, the cam disk comprises a transition region between the first step and the second step defining a rotational path of the cam disk during the first rotation. The transition region can be configured such that no further force threshold is felt after the first force threshold has been overcome until the second shoulder and thus the second force threshold has been reached. In other design variants, the transition region can be configured such that the force also increases slightly after overcoming the first force threshold, whereby a slight resistance is felt even after overcoming the first force threshold, until it increases again abruptly once the second shoulder is reached.
According to a further embodiment, the first step is formed by a ledge or nose of the cam disk.
According to a further embodiment, the biasing element comprises a metal spring configured to contact the cam disk with a first end. The biasing element configured as a metal spring has the advantage that it is inexpensive and robust.
According to a further embodiment, the biasing element comprises a plastic attachment arranged on the first end of the biasing element. With the plastic attachment, a high precision is achieved in addition to the inexpensive and robust metal spring, because the plastic element is very precisely adaptable to the shape of the cam disk.
According to a further embodiment, the biasing element comprises a plastic spring. According to this embodiment, a particularly precise transmission of force between the cam disk and the biasing element can occur.
According to a further embodiment, the kinematics is configured such that the first rotation of the cam disk serves to activate the signal transmitter and/or wherein the kinematics is configured such that the second rotation of the cam disk serves to activate an emergency release.
In a further aspect, the present disclosure relates to a vehicle door having an actuating mechanism as described above.
It is noted at this point that the actuator 104 according to
The first end 205 of the biasing element 206 configured as a metal spring, shown in a J-shape here, initially comes into contact with a first shoulder 208 of the cam disk 204 according to
By overcoming the first force threshold, a first rotation of the cam disk 204 in relation to the biasing element is released. Accordingly, the latter can move clockwise. The biasing element prevents a movement of the cam disk 204 until the first force threshold is overcome and the biasing element 206 is elastically deformed.
At this time, the first end of the biasing element is guided on a transition surface 210 (here, a straight surface) of the cam disk 204 until the biasing element 206 meets a downstream second shoulder 212 of the cam disk 204. The length of the transition surface 210 between the first shoulder 208 and the second shoulder 212 determines how far the cam disk 204 can be rotated after overcoming the first force threshold. Thus, using the extent of the transition surface 210, it can be determined in particular how far the actuator (cf.
Once the cam disk 204 has been rotated so far that the first end 205 of the biasing element 206 comes into contact with the second shoulder 212, the user in turn feels haptic feedback from the resistance now generated. This resistance generated by the second shoulder 212 results in a second force threshold, which can be higher than the first force threshold. For example, this is achieved in that the second shoulder 212 is wider than the first shoulder 208 and thus prevents the cam disk 204 from rotating further until the biasing element 206 is further compressed than was the case due to the first shoulder 208. In other words, the user feels a stop at this point, which, however, can be overcome with a sufficient force input (higher than the second force threshold), for example in order to activate an emergency release. The emergency release can be achieved, for example, via a Bowden pull, but this does not restrict the scope of the disclosure. To accommodate a Bowden pull, the kinematics 200 comprises a hook 216, which is connected to the cam disk 204, in particular integrally.
