The present disclosure relates generally to door systems for motor vehicles and, more particularly, to a power swinging vehicle door and anti-pinch devices therefor.
This section provides background information related to the present disclosure which is not necessarily prior art.
Passenger doors on motor vehicles are typically mounted by upper and lower door hinges to the vehicle body for swinging movement about a generally vertical pivot axis. Each door hinge typically includes a door hinge strap connected adjacent to a leading front edge of the passenger door, a body hinge strap connected to the vehicle body, and a pivot pin arranged to pivotably connect the door hinge strap to the body hinge strap and define the pivot axis. Such swinging passenger doors (“swing doors”) have recognized issues such as, for example, when the vehicle is situated on an inclined surface and the swing door either opens too far or swings shut due to the unbalanced weight of the door. To address this issue, most passenger doors have some type of detent or check mechanism integrated into at least one of the door hinges that functions to inhibit uncontrolled swinging movement of the door by positively locating and holding the door in one or more mid-travel positions in addition to a fully-open position. In some high-end vehicles, the door hinge may include an infinite door check mechanism which allows the door to be opened and held in check at any desired open position. One advantage of passenger doors equipped with door hinges having an infinite door check mechanism is that the door can be located and held in any position to avoid contact with adjacent vehicles or structures.
In view of increased consumer demand for motor vehicles equipped with advanced comfort and convenience features, many current vehicles are now provided with passive keyless entry systems to permit locking and release of the passenger doors without the use of traditional key-type manual entry systems. In this regard, some of the more popular features now provided with vehicle closure systems include power locking/unlocking and power release. These “powered” features are typically integrated into a primary latch assembly mounted to the passenger door adjacent a trailing rear edge of the passenger door and which is configured to include a latch mechanism, a latch release mechanism and at least one electric actuator. As is known, movement of the passenger door to its closed position causes the latch mechanism to engage a striker (mounted to the vehicle body) and shift the primary latch assembly into a latched mode. To subsequently release the passenger door for movement from its closed position toward an open position, an electric “power release” actuator can actuate the latch release mechanism to mechanically release the striker from the latch mechanism and shift the primary latch assembly into an unlatched mode.
Typically, power door actuation systems include a power-operated device such as, for example, a power swing door actuator having an electric motor and a rotary-to-linear conversion device that are operable for converting the rotary output of the electric motor into translational movement of an extensible member. In many power door actuator arrangements, the power swing door actuator is mounted to the passenger door and the distal end of the extensible member is fixedly secured to the vehicle body. One example of a door-mounted power door actuation system is shown in commonly-owned U.S. Pat. No. 9,174,517 with a power swing door actuator having a rotary-to-linear conversion device configured to include an externally-threaded leadscrew rotatively driven by the electric motor and an internally-threaded drive nut meshingly engaged with the leadscrew and to which the extensible member is attached. Accordingly, control over the speed and direction of rotation of the leadscrew results in control over the speed and direction of translational movement of the drive nut and the extensible member for controlling swinging movement of the passenger door between its open and closed positions. Operation of the power swing door actuator is controlled in coordination with the power release operation of the primary latch assembly via the passive keyless entry system.
Some other door actuation systems, known as door presenter systems, are configured to include a power-operated door presenter assembly operable to “present” the door by opening it only a predetermined amount to a partially-open position so as to allow subsequent manual movement of the door to its fully-open position. Presenter systems are commonly used on handleless doors to allow the passenger to grasp the trailing rear edge of the presented door in order to manually swing the door to a fully open position.
While such power door systems function satisfactorily for their intended purpose, one recognized drawback relates to a potential pinch point created between a rear passenger door and a front passenger door. For example, when the rear passenger door is in an open position, and a passenger grasps the trailing rear edge of the front passenger door to open the front passenger door, a gap formed between the leading front edge of the rear passenger door and the trailing rear edge of the front passenger door can create a potential pinch point if while the passenger is grasping the rear trailing edge of the front passenger door, the rear passenger is suddenly closed. In the aforementioned scenario, the leading front edge of the rear passenger door may pinch the passenger's fingers present in the gap against the trailing rear edge of the front passenger door.
In view of the above, there remains a need to develop a handleless power door mechanism which addresses and remedies potential pinch points associated with known power door arrangements, while minimizing the cost and complexity associated therewith.
This section provides a general summary of the present disclosure and is not a comprehensive disclosure of its full scope or all of its features, aspects and objectives.

These and other aspects, features, and advantages of the present disclosure will be readily appreciated, as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings wherein:
In general, several example embodiments of an anti-pinch mechanism for a motor vehicle swing door constructed in accordance with the teachings of the present disclosure will now be disclosed. Each of the example embodiments is provided so that this disclosure will be thorough, and will fully convey the scope to those who are skilled in the art. Numerous specific details are set forth such as examples of specific components, devices, and methods, to provide a thorough understanding of embodiments of the present disclosure. It will be apparent to those skilled in the art that specific details need not be employed, that example embodiments may be embodied in many different forms and that neither should be construed to limit the scope of the disclosure. In some example embodiments, well-known processes, will-known device structures, and well-known technologies are described in detail.
The terminology used herein is for the purpose of describing particular example embodiments only and is not intended to be limiting. As used herein, the singular forms “a,” “an,” and “the” may be intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms “comprises,” “comprising,” “including,” and “having,” are inclusive and therefore specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring their performance in the particular order discussed or illustrated, unless specifically identified as an order of performance. It is also to be understood that additional or alternative steps may be employed.
When an element or layer is referred to as being “on,” “engaged to,” “connected to,” or “coupled to” another element or layer, it may be directly on, engaged, connected or coupled to the other element or layer, or intervening elements or layers may be present. In contrast, when an element is referred to as being “directly on,” “directly engaged to,” “directly connected to,” or “directly coupled to” another element or layer, there may be no intervening elements or layers present. Other words used to describe the relationship between elements should be interpreted in a like fashion (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.
Although the terms first, second, third, etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms may be only used to distinguish one element, component, region, layer or section from another region, layer or section. Terms such as “first,” “second,” and other numerical terms when used herein do not imply a sequence or order unless clearly indicated by the context. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the example embodiments.
Spatially relative terms, such as “inner,” “outer,” “beneath,” “below,” “lower,” “above,” “upper,” “top”, “bottom”, and the like, may be used herein for ease of description to describe one element's or feature's relationship to another element(s) or feature(s) as illustrated in the figures.

Thus, the example term “below” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated degrees or at other orientations) and the spatially relative descriptions used herein interpreted accordingly.
To better describe and illustrate the inventive aspects of the present disclosure, initial reference is directed to
Power door actuation system 20 is shown schematically to include a latch assembly 21 and a presenter assembly 22. Latch assembly 21 is mounted to front door 12 and includes (in this non-limiting configuration) a latch mechanism configured to engage a striker (not shown) provided on the vehicle body 14, a power-operated latch release mechanism, and a power-operated lock mechanism. Latch assembly 21 is defined to be operating in a locked-latched mode when the latch mechanism is latched and the lock mechanism is locked for holding front door 12 in a locked-closed position. Latch assembly 21 is also defined to be operating in an unlocked-latched mode when the latch mechanism is latched and the lock mechanism is unlocked for holding front door 12 in an unlocked-closed position. Finally, latch assembly 21 is defined to be operating in an unlatched mode when the latch mechanism is released and the lock mechanism is unlocked so as to permit movement of front door 12 from its unlocked-closed position toward a fully-open position. At least one electrically-powered latch actuator is provided in association with latch assembly 21 for controlling operation of the latch release and lock mechanism to provide a power release function and a power lock function. An activation command signal generated by an authentication device is used by a latch controller to initiate operation of the electric latch actuator to provide the desired power release and power lock functions. The authentication device is associated with a passive keyless entry system and may include, without limitation, a key fob, a contact or non-contact interface provided on front door 12, and a voice recognition interface. The specific details of latch assembly 21 and its activation protocol are not required as those skilled in the art understand the provisions of the power release and power lock functionality discussed above.
Power door actuation system 20 is diagrammatically shown in
Although not expressly illustrated, electric motor 24 can include Hall-effect sensors for monitoring a position and speed of vehicle door 12 during movement between its open and closed positions. For example, one or more Hall-effect sensors may be provided and positioned to send signals to electronic control module 52 that are indicative of rotational movement of electric motor 24 (e.g. a motor shaft) and indicative of the rotational speed of electric motor 24, e.g., based on counting signals from the Hall-effect sensor detecting a target on a motor output shaft. In situations where the sensed motor speed is greater than a threshold speed and where the current being supplied to the motor 24 (e.g. as detected by a current sensor or sensing circuitry) registers a significant change in the current draw, electronic control module 52 may determine that the user is manually moving door 12 while motor 24 is also operating, thus moving vehicle door 12. Electronic control module 52 may then send a signal to electric motor 24 to stop motor 24 and may even disengage slip clutch 28 (if provided) to facilitate manual override movement. Conversely, when electronic control module 52 is in a power open or power close mode and the Hall-effect sensors indicate that a speed of electric motor 24 is less than a threshold speed (e.g., zero) and a current spike is registered either directly or indirectly by microprocessor 54 and/or any current sensing circuitry, electronic control module 52 may determine that an obstacle is in the way of vehicle door 12, in which case the electronic control system may take any suitable action, such as sending a signal to turn off electric motor 24. As such, electronic control module 52 receives feedback from the Hall-effect sensors to ensure that a contact obstacle has not occurred during movement of vehicle door 12 from the closed position to the partially-open position, or vice versa. Other position sensing techniques to determine that the vehicle door 12 is being moved, either by the electrical motor 24 and/or a manual user control are also possible.
As is also schematically shown in
Electronic control module 52 can also receive an additional input from proximity sensor, such as an ultrasonic sensor 64 positioned on a portion of vehicle door 12, such as on a door mirror 65 or the like. Ultrasonic sensor 64 detects if an obstacle, such as another car, tree, or post, is near or in close proximity to vehicle door 12. If such an obstacle is present, ultrasonic sensor 64 will send a signal to electronic control module 52 and electronic control module 52 will proceed to turn off electric motor 24 to stop movement of vehicle door 12, thereby preventing vehicle door 12 from hitting the obstacle. This provides a non-contact obstacle avoidance system. In addition, or optionally, a contact obstacle avoidance system, such as a pinch detection system, can be placed in vehicle 10 which includes a contact sensor 66 mounted to door, such as in association with molding component 67, and which is operable to send a signal to controller 52 that an obstacle is detected, such as a user's finger detected in a gap between the vehicle body 14 and the door 12. Although the electronic pinch detection can be provided if desired, a simplified real-time anti-pinch prevention mechanism, referred to hereafter as anti-pinch shield 100 is provided in accordance with the disclosure, discussed further below, which functions mechanically and simply to prevent an object, such as a user's finger(s) from being pinched in a gap between the vehicle body 14 and the door 12.
Power door actuation system 20 is also shown schematically in
Referring to
The anti-pinch shield 100 has a first body 104 providing a mount surface 106 configured for fixed attachment to a body 14 of the motor vehicle 10, between at least one leading front edge 15, 15′ of at least one of the respective front and rear swing doors 12, 12′, and one of a trailing rear edge 23 of an adjacent swing door 12 and an adjacent vehicle panel 108. In one non-limiting embodiment, the mount surface 106 of one anti-pinch shield 100 can be attached to at least one of the B-pillar 13 of the motor vehicle 10, between and/or adjacent the trailing rear edge 23 of the front passenger swing door 12 and the leading front edge 15′ of the rear passenger swing door 12′, and the A-pillar 11 of the motor vehicle 10, between the leading front edge 15 of the front passenger swing door 12 and an adjacent trailing edge 108′ of a front vehicle panel 108, such as a front quarter panel, such as that forming a front fender of the motor vehicle 10, by way of example and without limitation. The first body 104 has a shape the fills or substantially fills the gap G, shown as being generally triangular to match the peripheral shaped of the gap G. The first body 104 has an arcuate surface 110, shown as being concave, facing opposite the mount surface 106 outwardly toward an outer environment. The arcuate surface 110 has a geometric contour that matches or substantially matches (closes approximates by not identical) the arc of travel of a respective one of the leading front edge 15′ of the rear passenger swing door 12′ and the leading front edge 15 of the front passenger swing door 12. As such, the contour of the arcuate surface 110 has a smooth radius, whether constant or varying, such as a logarithmic curve. By way of example and without limitation, the anti-pinch shield 100 is shown disposed on the B-pillar 13, though it is to be recognized that, as discussed above, it can also be disposed on the A-pillar 11.
To facilitate attachment of the first body 104 to the respective A and/or B pillar 11, 13, the first body 104 has at least one, and shown as a pair of through openings 112, by way of example and without limitation, extending through the arcuate surface 110 and the mount surface 106. The through openings 112 have a counterbore 114 extending into the arcuate surface 110, wherein the counterbores 114 are sized and configured for full receipt of a head 116 of a fastener 118 therein. As such, the head 116 of the fastener 118 is fully recessed below the arcuate surface 110 to avoid interference with the leading front edge 15′ of the rear passenger door 12′.

It is to be recognized that the anti-pinch shield 100 is readily attachable to a B-pillar 13 of an existing vehicle not originally equipped with the anti-pinch shield 100, or it can be assembled at an original equipment manufacturer. The anti-pinch shield 100 functions mechanically in real-time to sweep the object O outwardly without pinching the object O, and thus, reliance on signals from sensors is negated, thereby doing away with inherent delays present with sensors. Further, the anti-pinch shield is economical in manufacture, such as via a molding process, by way of example and without limitation, and is further economical in assembly.
It is to be further recognized, as discussed above, the anti-pinch shield 100 can be attached to the A-pillar 11 of the motor vehicle 10, between the leading front edge 15 of the front passenger swing door 12 and an adjacent trailing edge 108′ of a front vehicle panel 108. Although this region is not considered a grasp area, as discussed above for the B-pillar grasp area 102, it can still present a pinch point. Accordingly, the anti-pinch shield 100 discussed above can be shaped having an outer periphery, as desired, to fill the geometric shape of a potential pinch area between the front passenger swing door 12 and the adjacent front vehicle panel 108.
In accordance with another aspect of the disclosure, a method 1000 of blocking a potential pinch region P between a leading front edge 15, 15′ of a swing door 12, 12′ and at least one of a trailing rear edge 23, 108′ of an adjacent swing door, such as front passenger swing door 12, and an adjacent vehicle panel 108 of a motor vehicle 10. The method 1000 includes a step 1050 of providing a first body 104 having a mount surface 106 and an arcuate anti-pinch surface 110 facing away from the mount surface 106. Further, a step 1100 of attaching the mount surface 106 of the first body 104 to a fixed body member 11, 13 of the motor vehicle 10, adjacent the leading front edge 15, 15′ of the swing door 12, 12′, and adjacent at least one of the trailing rear edge 23 and the adjacent vehicle panel 108.
It is a further aspect of the method 1000 to include a step 1150 of providing the arcuate surface 110 having a contour that matches an arc of travel of the leading front edge 15, 15′ of the swing door 12, 12′.
It is a further aspect of the method 1000 to include a step 1200 of attaching the mount surface 106 of the first body 104 to at least one of a B-pillar 13 and/or A-pillar 11 of the motor vehicle 10.
It is a further aspect of the method 1000 to include a step 1250 of attaching a second mount surface 106′ of a second body 104′ to a rear passenger swing door 12′ adjacent the leading front edge 15′ of the rear passenger swing door 12′ and providing the second body 104′ having a second contour shaped for close matching travel along the arcuate anti-pinch surface 110 of the first body 104 as the rear passenger swing door 12′ moves between an open and closed position.
It is a further aspect of the method 1000 to include a step 1300 of providing the arcuate anti-pinch surface 110 having a concave contour and providing the second contour having a convex contour shaped for close matching travel along of the concave contour as the rear passenger swing door 12′ moves between an open and closed position
The foregoing description of the several embodiments has been provided for purposes of illustration and description. It is not intended to be exhaustive or to limit the disclosure. Individual elements or features of a particular embodiment are generally not limited to that particular embodiment, but, where applicable, are interchangeable and can be used in a selected embodiment, even if not specifically shown or described. The same may also be varied in many ways. Such variations are not to be regarded as a departure from the disclosure, and all such modifications are intended to be included within the scope of the disclosure. Those skilled in the art will recognize that concepts disclosed in association with the example detection system can likewise be implemented into many other systems to control one or more operations and/or functions.
