The embodiments, examples, and alternatives of the preceding paragraphs, the claims, or the following description and drawings, including any of their various aspects or respective individual features, may be taken independently or in any combination. Features described in connection with one embodiment are applicable to all embodiments, unless such features are incompatible.
The various features and advantages of this disclosure will become apparent to those skilled in the art from the following detailed description. The drawings that accompany the detailed description can be briefly described as follows.
This disclosure details exemplary closure member systems for motor vehicles. Exemplary closure member systems may include a hinge assembly having an internal stop. The internal stop may be established by portions of both a stationary hinge component and a movable hinge component of the hinge assembly. For example, the stationary hinge component may include one or more ears that are arranged to contact one or more stop surfaces provided on the movable hinge component. The ears may engage the stop surfaces to limit a range of motion of the closure member. These and other features of this disclosure are described in greater detail below.
Although a specific component relationship is illustrated in the figures of this disclosure, the illustrations are not intended to limit this disclosure. In other words, the placement and orientation of the various components of the vehicle 10 are shown schematically and could vary within the scope of this disclosure. In addition, the various figures accompanying this disclosure are not necessarily drawn to scale, and some features may be exaggerated or minimized to emphasize certain details of a particular component, assembly, or system.
The vehicle 10 may include one or more closure members 12 that are mounted relative to a vehicle body 14 and configured to move between closed and open positions for accessing a vehicle interior (e.g., a cargo space, a passenger cabin, etc.). In the illustrated embodiment, the closure member 12 is mounted at a rear 16 of the vehicle 10 and is configured as a swing gate. In other implementations, the closure member 12 could be part of a dual out-swinging door system that may be provided at the rear 16 of the vehicle 10 for gaining access to the vehicle interior, such as for loading and/or unloading cargo, for example. However, the teachings of this disclosure are not limited to swing gates and rear out-swinging type doors and could apply to various other types of closure members, including but not limited to side doors, tailgates, hearse back doors, etc.
The closure member 12 may be movably mounted to the vehicle body 14 by a first hinge assembly 18 and a second hinge assembly 20. The first and second hinge assemblies 18. 20 may movably support the closure member 12 relative to the vehicle body 14. Together, the closure member 12, the first hinge assembly 18, and the second hinge assembly 20 may establish a closure member system 22 of the vehicle 10. Although two hinge assemblies are illustrated in the exemplary embodiment, the closure member system 22 could include a greater or fewer number of hinge assemblies.
The first hinge assembly 18 may be mounted at a location of the closure member 12 that is vertically above the second hinge assembly 20. However, other configurations could be possible within the scope of this disclosure. Vertical and horizontal, for purposes of this disclosure, are with reference to ground in an ordinary orientation of the vehicle 10 during operation.
In an embodiment, the first hinge assembly 18 and the second hinge assembly 20 are visible when the closure member 12 is closed. The first and second hinge assemblies 18, 20 may therefore be considered exposed or “Class A” hinge assemblies.
The design of the second hinge assembly 20 may be substantially identical to that of the first hinge assembly 18. Therefore, for the purposes of this disclosure, details described herein related to the first hinge assembly 18 should be understood to apply equally to the second hinge assembly 20.
The closure member 12 is shown in a closed position P1 in
In an embodiment, the closure member 12 is angularly displaced relative to the vehicle body 14 by about 100° or more when moved to the fully open position P2. In this disclosure, the term “about” means that the expressed quantities or ranges need not be exact but may be approximated and/or larger or smaller, reflecting acceptable tolerances, conversion factors, measurement error, etc. A total range of motion of the closure member 12 may vary and is dependent on various design criteria.
The first hinge assembly 18 may include a stationary hinge component 24 and a movable hinge component 26. The stationary hinge component 24 may be mounted to the vehicle body 14 by one or more mechanical fasteners (not shown), and the movable hinge component 26 may be mounted to an exterior surface 99 of the closure member 12 by one or more mechanical fasteners 28 (see
The stationary hinge component 24 may include a base portion 30 and a bracket portion 32, and the movable hinge component 26 may also include a base portion 34 and a bracket portion 36. The base portions 30, 34 may be configured to interface with one another, the bracket portion 32 of the stationary hinge component 24 may be mounted to the vehicle body 14, and the bracket portion 36 of the movable hinge component 26 may be mounted to the closure member 12 to movably support the closure member 12 relative to the vehicle body 14.
The movable hinge component 26 may be pivotably connected to the stationary hinge component 24 by a pivot pin 45. The pivot pin 45 may extend through openings provided by a first arm 38 of the base portion 34 of the movable hinge component 26, a barrel mount 42 of the base portion 30 of the stationary hinge component 24, and second arm 40 of the base portion 34 of the movable hinge component 26.
The first hinge assembly 18 may additionally include an internal stop 44 that is configured to limit the range of motion of the closure member 12 as it is moved between the closed position P1 and the fully open position P2. The internal stop 44 is therefore responsible for controlling the lower and upper limits of the swing path of the closure member 12. The internal stop 44 is contained inside (e.g., internal of) the first hinge assembly 18 and is therefore concealed and thus not visible from the exterior of the first hinge assembly 18.
The internal stop 44 may be established by features of both the stationary hinge component 24 and the movable hinge component 26. For example, the base portion 30 of the stationary hinge component 24 may include a beam 46 that protrudes radially outwardly from an outer circumferential surface 48 of the barrel mount 42 of the base portion 30. A first car 50 may extend outwardly in a first direction from the beam 46, and a second car 52 may extend outwardly in a second, opposite direction from the beam 46. The first direction and the second, opposite direction are both parallel to a pivot axis 55 of the barrel mount 42, in an embodiment.
The first arm 38 of the base portion 34 of the movable hinge component 26 may include a pair of stop surfaces 54A, 54B, and the second arm 40 of the base portion 34 of the movable hinge component 26 may include another pair of stop surfaces 56A, 56B. The stop surfaces 54A, 54B may be provided within a first cavity 58 formed in the first arm 38, and the stop surfaces 56A, 56B may be provide within a second cavity 60 formed in the second arm 40. The stop surfaces 54A, 54B may each extend at an angle relative to a first pivot pin boss 62 of the first arm 38, and the stop surfaces 56A, 56B may each extend at an angle relative to a second pivot pin boss 64 of the second arm 40.
In an assembled condition of the first hinge assembly 18, the barrel mount 42 may be accommodated within the open space between the first arm 38 and the second arm 40. The barrel mount 42 may therefore be flanked by the first arm 38 and the second arm 40. As the movable hinge component 26 is rotated about the pivot axis 55, the first car 50 may be accommodated within the space afforded by the first cavity 58 and the second car 52 may be accommodated within the space afforded by the second cavity 60. The first car 50 may engage the stop surface 54A and the second car 52 may engage the stop surface 56A to arrest further movement in a first direction D1 beyond the closed position P1 (see
The vehicle closure member systems described herein provide a simple and robust manner for opening and closing vehicle closure members while providing an internal stop. The proposed systems provide the internal stop feature without adding additional components or increasing the necessary packaging space required by the closure member system. The internal stop is further provided without influencing styling at the expense of the functional requirements of the closure member system.
Although the different non-limiting embodiments are illustrated as having specific components or steps, the embodiments of this disclosure are not limited to those particular combinations. It is possible to use some of the components or features from any of the non-limiting embodiments in combination with features or components from any of the other non-limiting embodiments.
It should be understood that like reference numerals identify corresponding or similar elements throughout the several drawings. It should be understood that although a particular component arrangement is disclosed and illustrated in these exemplary embodiments, other arrangements could also benefit from the teachings of this disclosure.
The foregoing description shall be interpreted as illustrative and not in any limiting sense. A worker of ordinary skill in the art would understand that certain modifications could come within the scope of this disclosure. For these reasons, the following claims should be studied to determine the true scope and content of this disclosure.
