[0032] The present disclosure describes in detail an exemplary opening and closing member system for a motor vehicle. The exemplary opening and closing member system may include a hinge assembly having an internal stop. The internal stop may be established by portions of both a fixed hinge component and a movable hinge component of the hinge assembly. For example, the fixed hinge component may include one or more ears that are arranged to contact one or more stop surfaces disposed on the movable hinge component. The ears may engage the stop surfaces to limit the range of motion of the opening and closing member. These and other features of the present disclosure are described in more detail below.
[0033] Figure 1 and Figure 2 Selected portions of a motor vehicle 10 (hereinafter referred to simply as the "vehicle") are schematically illustrated. Vehicle 10 may be a car, truck, van, sport utility vehicle, hearse, semi-tractor trailer, or any other type of vehicle. Vehicle 10 may also be a conventional motor vehicle, a traction battery powered hybrid or electric vehicle, or an autonomous vehicle (i.e., a driverless vehicle).
[0034] Although specific component relationships are shown in the drawings of the present disclosure, the illustrations are not intended to limit the present disclosure. In other words, the layout and orientation of the various components of the vehicle 10 are shown schematically only and may vary within the scope of the present disclosure. In addition, the various drawings attached to the present 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.
[0035] The vehicle 10 may include one or more opening and closing members 12, which are mounted relative to the vehicle body 14 and are configured to move between a closed position and an open position for access to the interior of the vehicle (e.g., a cargo compartment, a passenger compartment, etc.). In the illustrated embodiment, the opening and closing member 12 is mounted at the rear 16 of the vehicle 10 and is configured as a swing door. In other embodiments, the opening and closing member 12 may, for example, be part of a two-way outward swinging door system that may be disposed at the rear 16 of the vehicle 10 for access to the interior of the vehicle, such as for loading and / or unloading cargo. However, the teachings of the present disclosure are not limited to swinging doors and rear outward swinging doors, and may be applied to various other types of opening and closing members, including but not limited to side doors, tailgates, tailgates, rear doors of hearses, etc.
[0036] The opening and closing member 12 may be movably mounted to the vehicle body 14 via a first hinge assembly 18 and a second hinge assembly 20. The first hinge assembly 18 and the second hinge assembly 20 may movably support the opening and closing member 12 relative to the vehicle body 14. The opening and closing member 12, the first hinge assembly 18, and the second hinge assembly 20 may together establish an opening and closing member system 22 of the vehicle 10. Although two hinge assemblies are shown in the exemplary embodiment, the opening and closing member system 22 may include a greater or lesser number of hinge assemblies.
[0037] The first hinge assembly 18 can be mounted at a location of the opening and closing member 12 that is vertically above the second hinge assembly 20. However, other configurations are possible within the scope of the present disclosure. For the purposes of this disclosure, vertical and horizontal are referenced to the ground in the normal orientation of the vehicle 10 during operation.
[0038] In one embodiment, the first hinge assembly 18 and the second hinge assembly 20 are visible when the opening and closing member 12 is closed. Therefore, the first hinge assembly 18 and the second hinge assembly 20 can be considered as exposed or "Class A" hinge assemblies.
[0039] The design of the second hinge assembly 20 may be substantially the same as the design of the first hinge assembly 18. Therefore, for purposes of this disclosure, details described herein in relation to the first hinge assembly 18 should be understood to be equally applicable to the second hinge assembly 20.
[0040] The opening and closing member 12 is Figure 1 is shown in the closed position P1 and in Figure 2 1 is shown in the fully open position P2. When moved to the fully open position P2, the opening and closing member 12 allows a user to enter and exit the vehicle interior. When closed, the opening and closing member 12 provides a barrier between the interior and exterior of the vehicle 10. Although not specifically shown, the opening and closing member 12 can be moved to various angular positions between the closed position P1 and the fully open position P2.
[0041] In one embodiment, when moved to the fully open position P2, the opening and closing member 12 is angularly displaced about 100° or more relative to the vehicle body 14. In the present disclosure, the term "about" indicates that the amount or range expressed need not be exact, but may be approximate and / or larger or smaller, thereby reflecting acceptable tolerances, conversion factors, measurement errors, etc. The total range of motion of the opening and closing member 12 may vary and depends on various design criteria.
[0042] Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 Shown with Figure 1 and Figure 2For the sake of simplicity, since the second hinge assembly 20 is understood to include the same design as the first hinge assembly 18, Figures 3 to 7 Only the first hinge assembly 18 is shown and described with respect to the opening and closing member 12 and the vehicle body 14 .
[0043] The first hinge assembly 18 may include a fixed hinge component 24 and a movable hinge component 26. The fixed 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 the vehicle body 14 by one or more mechanical fasteners 28 (see FIG. Figure 3 ) is mounted to an outer surface 99 of the shutter member 12. The outer surface 99 may be referred to as the "Class A surface" of the shutter member 12.
[0044] The fixed 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 abut against each other, the bracket portion 32 of the fixed 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 opening and closing member 12 to movably support the opening and closing member 12 relative to the vehicle body 14.
[0045] The movable hinge component 26 can be pivotally connected to the fixed hinge component 24 by a pivot pin 45. The pivot pin 45 can extend through an opening provided by the first arm 38 of the base portion 34 of the movable hinge component 26, the barrel mount 42 of the base portion 30 of the fixed hinge component 24, and the second arm 40 of the base portion 34 of the movable hinge component 26.
[0046] The first hinge assembly 18 may further include an internal stopper 44 configured to limit the range of motion of the opening and closing member 12 when it moves between the closed position P1 and the fully open position P2. Thus, the internal stopper 44 is responsible for controlling the lower and upper limits of the swing path of the opening and closing member 12. The internal stopper 44 is included on the inner side (e.g., inside) of the first hinge assembly 18 and is therefore hidden and therefore not visible from the outside of the first hinge assembly 18.
[0047] The internal stop 44 can be established by features of the fixed hinge component 24 and the movable hinge component 26. For example, the base portion 30 of the fixed hinge component 24 can include a beam 46 that projects radially outward from the outer circumferential surface 48 of the barrel mount 42 of the base portion 30. The first ear 50 can extend outward from the beam 46 in a first direction, and the second ear 52 can extend outward from the beam 46 in an opposite second direction. In one embodiment, the first direction and the opposite second direction are both parallel to the pivot axis 55 of the barrel mount 42.
[0048] The first arm 38 of the base portion 34 of the movable hinge member 26 may include a pair of stop surfaces 54A, 54B, and the second arm 40 of the base portion 34 of the movable hinge member 26 may include another pair of stop surfaces 56A, 56B. The stop surfaces 54A, 54B may be disposed within a first cavity 58 formed in the first arm 38, and the stop surfaces 56A, 56B may be disposed 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.
[0049] In the assembled state of the first hinge assembly 18, the barrel mount 42 can be received in the open space between the first arm 38 and the second arm 40. Therefore, the barrel mount 42 can be flanked by the first arm 38 and the second arm 40. When the movable hinge component 26 rotates about the pivot axis 55, the first ear 50 can be received in the space provided by the first cavity 58, and the second ear 52 can be received in the space provided by the second cavity 60. The first ear 50 can engage the stop surface 54A, and the second ear 52 can engage the stop surface 56A to prevent further movement in the first direction D1 beyond the closed position P1 (see Figure 4 ). The first ear 50 can engage the stop surface 54B and the second ear 52 can engage the stop surface 56B to prevent further movement in the second direction D2 beyond the fully open position P2 (see Figure 5 ). Thus, the first ear 50 , the second ear 52 , and the stop surfaces 54A, 54B, 56A, and 56B may cooperate to provide the inner stop 44 .
[0050] The vehicle opening and closing member system described herein provides a simple and robust way for opening and closing the vehicle opening and closing member while providing an internal stop. The proposed system provides an internal stop feature without adding additional components or increasing the necessary packaging space required for the opening and closing member system. The internal stop is further provided without affecting the styling at the expense of the functional requirements of the opening and closing member system.
[0051] Although different non-limiting embodiments are shown as having specific components or steps, the embodiments of the present disclosure are not limited to these specific combinations. Some components or features from any one of the non-limiting embodiments may be used in combination with features or components from any one of the other non-limiting embodiments.
