Description

TECHNICAL FIELD

The present disclosure relates to a hinge assembly for movably coupling a vehicle body to a vehicle door.

BACKGROUND

Vehicles, such as cars, include a vehicle body and a vehicle door movable relative to the vehicle body between an open position and a closed position. To couple the door to the vehicle body, the vehicle may include a hinge assembly. The hinge assembly can pivotally couple the vehicle door to the vehicle body.

SUMMARY

It is useful to enhance the structural integrity of the hinge assembly in order to maintain the vehicle door coupled to vehicle body, especially when the vehicle is subjected to an external force. To this end, the present disclosure describes a hinge assembly capable of maintaining the vehicle door coupled to the vehicle door even when an external force is applied to the vehicle. In an embodiment, a hinge assembly includes a body strap having a main body. The main body defines a first surface end and a second surface opposite the first body end. The body strap includes a first pin support and a second pin support. The first and second pin supports extend from the main body. The body strap includes a protrusion extending from the second body end of the main body. The protrusion defines a first protrusion end and a second protrusion end opposite the first protrusion end. A first distance is defined from the second surface to the second protrusion end in a direction orthogonal to the second surface. The hinge assembly further includes a door strap partially disposed between the first and second pin supports. Further, the hinge assembly includes a pin movably interconnecting the body strap and the door strap. The pin extends along an axis and is supported by the first and second pin supports. A second distance is defined from the second surface to the axis along the direction orthogonal to the second surface. The first distance is greater than the second distance. The protrusion may include an annular body at least partially surrounding the pin.
The present disclosure also relates to a vehicle including a vehicle body, a vehicle door, and a hinge assembly as described above. The hinge assembly movably couples the vehicle door to the vehicle body.
The above features and advantages and other features and advantages of the present invention are readily apparent from the following detailed description of the best modes for carrying out the invention when taken in connection with the accompanying drawings.

DETAILED DESCRIPTION

Referring to the drawings, wherein like reference numbers correspond to like or similar components throughout the several figures, FIG. 1 schematically illustrates a vehicle 10 including a vehicle body 12, a vehicle door 14, and a hinge assembly 16 movably coupling the vehicle door 14 to the vehicle body 12. The vehicle 10 may be a car or any other land, air, or sea vehicle. Regardless of the kind of vehicle 10, the hinge assembly 16 allows the vehicle door 14 to move (e.g., pivot) relative to the vehicle body 12 between an open position and a closed position.
The hinge assembly 16 includes a body strap 18, a door strap 20, and a pin 22 movably coupling the door strap 20 to the body strap 18. As such, the door strap 20 can move relative to the body strap 18. For example, the pin 22 can rotatably (e.g., pivotally) couple the door strap 20 to the body strap 18. Consequently, the door strap 20 can rotate (e.g., pivot) relative to the body strap 18. The body strap 18, the door strap 20, and the pin 22 are wholly or partly made of a substantially rigid material, such as a metal, metal alloy, a rigid polymeric material, or a combination thereof.
The body strap 18 is coupled to the vehicle body 12. In particular, the body strap 18 is fixed to the vehicle body 12. Accordingly, the vehicle body 12 remains stationary relative to the body strap 18. As a non-limiting example, at least one fastener 24, such as a screw or bolt, can fix the body strap 18 to the vehicle body 12. In the depicted embodiment, two fasteners 24 fix the vehicle body 12 to the body strap 18.
The door strap 20 is coupled to the vehicle door 14. In particular, the door strap 20 is fixed to the vehicle door 14. Accordingly, the vehicle door 14 remains stationary relative to the door strap 20. As a non-limiting example, at least one fastener 24, such as a screw or bolt, can fix the door strap 20 to the vehicle door 14. In the depicted embodiment, two fasteners 24 fix the vehicle door 14 to the door strap 20.
With reference to FIGS. 2-4, the body strap 18 includes a main body 26 extending along a first axis A. In other words, the main body 26 extends along a first direction X. The main body 26 defines a first body end 36 and a second body end 38 opposite the first body end 36. The first body end 36 is spaced apart from the second body end 38 along the first direction X. Moreover, the body strap 18 defines at least one body hole 28 extending through the main body 26. In the depicted embodiment, the body strap 18 defines two body holes 28. It is contemplated, however, that the body strap 18 may have more or fewer body holes 28. Irrespective of the quantity, each body hole 28 is configured, shaped, and sized to receive at least one fastener 24.
The main body 26 also defines a first or top surface 27 and a second or bottom surface 29 opposite the first surface 27. The second surface 29 is spaced apart from the first surface 27 along a second direction Y. The second direction Y is substantially perpendicular to the first direction X. Further, the second direction Y may be referred to as “a direction orthogonal to the second surface 29” or as “a direction orthogonal to the first surface 29.”
The body strap 18 includes a first pin support 30 and a second pin support 32 each configured to support the pin 22. Each of the first and second pin supports 30, 32 extends from the main body 26 along a second axis B. The second axis B is substantially perpendicular to the first axis A. Each of the first and second pin supports 30, 32 extends from the main body 26 along the second direction Y. Furthermore, the first pin support 30 is spaced apart from the second pin support 32 along a third direction Z. The third direction Z is substantially perpendicular to the first direction X and the second direction Y. The pin 22 extends along the third direction Z and is supported by the first and second pin supports 30, 32. The body strap 18 also defines pin body holes 34 extending through the first pin support 30 and the second pin support 32. In particular, one pin body hole 34 extends through the first pin support 30, and another pin body hole 34 extends through the second pin support 32. Each of the pin body holes 34 is configured, shaped, and sized to receive at least a portion of the pin 22. When the pin 22 extends through the pin body holes 34, the first and second pin supports 30, 32 carry the pin 22, thereby coupling the pin 22 to the body strap 18. In other words, the pin 22 is supported by the first and second pin supports 30, 32.
The body strap 18 further includes a protrusion 40 extending from the main body 26. In the depicted embodiment, the protrusion 40 is configured as a column and extends from the second body end 38 of the main body 26 along the second direction Y. As such, at least a portion of the protrusion 40 is disposed over the pin 22 such that the protrusion 40 at least partially overlaps the pin 22 along the first direction X. Placing the protrusion 40 over the pin 22 helps maintain the pin 22 connected to the body strap 18 and the door strap 20 when an external force is applied to the vehicle 10 (FIG. 1). In the depicted embodiment, the protrusion 40 only partially overlaps the pin 22 at least along the third direction Z. In other words, the protrusion 40 extends from the second body end 38 along the second direction such that the pin is at least partially aligned with the protrusion along the first direction X.
The protrusion 40 defines a first protrusion end 45 and a second protrusion end 47 opposite the first protrusion end 45. The first protrusion end 45 is directly coupled to the main body 26, whereas the second protrusion end 47 may be free. That is, the second protrusion end 47 may be decoupled from the rest of the main body 26. In other words, the second protrusion end 47 is only coupled to the main body 26 through the first protrusion end 45. A first distance D1 is defined from the second surface 45 of the main body 26 to the second protrusion end 47 in a direction orthogonal to the second surface (i.e., the second direction Y).
The protrusion 40 may include a structural integrity feature 49 for enhancing the structural integrity of the protrusion 40. It is useful to enhance the structural integrity of the protrusion 40 in order to minimize separation of the pin 22 from the body strap 18 and the door strap 20. The structural integrity feature 49 may be an undulation 51 that may extend at least from the first protrusion end 45 to the second protrusion end 47.
The door strap 20 includes a first door connection section 42, and a second door connection section 44, and a pin connection section 46 interconnecting the first and second door connection sections 42, 44. The first and second door connection sections 42, 44 extend substantially along the third direction Z, and the protrusion 40 is disposed between the first and second door connection sections 42, 44. The pin connection section 46 is disposed between the first pin support 30 and the second pin support 32. The first and second door connection sections 42, 44 extend along the third direction Z and are each directly coupled to the door 14 (FIG. 1). The door strap 20 defines a first section hole 48 extending through the first door connection section 42 and a second section hole 50 extending through the second door connection section 44. The first and second section holes 48, 50 are each configured, shaped, and sized to receive at least one fastener 24 (FIG. 1). Accordingly, the fasteners 24 (FIG. 1) can be disposed in the first and second section holes 48, 50 to fix the body strap 18 to the vehicle door 14.
The pin connection section 46 is disposed between the first and second door connection sections 42, 44 and may have a C-shape. In particular, the pin connection section 46 is entirely disposed between the first and second pin supports 30, 32. In the depicted embodiment, the pin connection section 46 includes a first wall 52 directly connected to the first door connection section 42, a second wall 54 directly connected to the second door connection section 44, and a third wall 56 directly interconnecting the first and second walls 52, 54. The protrusion 40 is disposed between the first and second walls 52, 54. The first and second walls 52, 54 may extend along the first direction X, while the third wall 56 may extend along the third direction Z. However, the first, second, and third walls 52, 54 56 may have other structural arrangements relative to one another. Regardless of their specific arrangements, the first, second, and third walls 52, 54, 56 may be entirely disposed between the first and second pin supports 30, 32. Accordingly, the door strap 20 is partially disposed between the first and second pin supports 30, 32. The pin 22 extends through the first and second walls 52, 54.
The door strap 20 further defines at least one pin opening 58 extending through the pin connection section 46. In the depicted embodiment, one pin opening 58 extends through the first wall 52, and another pin opening 58 extends through the second wall 54. Irrespective of their exact location and quantity, each pin opening 58 is configured, shaped, and sized to receive the pin 22 such that the door strap 20 is capable of rotating about the pin 22. Thus, when the pin openings 58 receive the pin 22, the door strap 20 can rotate (e.g., pivot) relative to the body strap 18 about the pin 22. Because the pin 22 extends through the pin connection section 46 along a third axis C, the door strap 20 can rotate (e.g., pivot) relative to the body strap 18 about the third axis C. The third axis C is substantially perpendicular to the first axis A and the second axis B.
As discussed above, the pin 22 extends through the first and second pin supports 30, 32 along the third axis C. Further, the pin 22 extends through a portion of the door strap 20 (e.g., the pin connection section 46) along the third direction Z. Specifically, the pin 22 extends through the first wall 52 and the second wall 54 along the third axis C. In the depicted embodiment, the pin 22 is fixed to the body strap 18 (via the first and second pin supports 30, 32) such that the pin 22 remains stationary relative to the body strap 18.
The pin 22 movably interconnects the body strap 18 and the door strap 20 and defines an outer surface 60. The outer surface 60 in turn defines an outer perimeter 62 of the pin 22. The outer perimeter 62 may be, for example, a circumference. For instance, the pin 22 may have a substantially cylindrical shape, and, in that case, the outer perimeter 62 is a circumference. It is envisioned, however, that the pin 22 may have other suitable shapes.
A second distance D2 is defined from the second surface 29 to the third axis C extending along the pin 22 in a direction orthogonal to the second surface 29 (i.e., the second direction Y). The third axis C may be simply referred to as an axis. The first distance D1 may be at least equal to the second distance D2. In the depicted embodiment, the first distance D1 is greater than the second distance D2.
FIGS. 5 and 6 depict a hinge assembly 100 in accordance with another embodiment of the present disclosure. The hinge assembly 100 is substantially similar to the hinge assembly 16 described above, except for the features described below. In the hinge assembly 100, at least part of the protrusion 40 is disposed around the outer perimeter 62 of the pin 22. In this embodiment, the protrusion 40 includes a protrusion body 41 directly connected to the second body end 38 of the main body 26 (as shown in FIG. 4) and an annular body 43 extending from the protrusion body 41. In this embodiment, the second protrusion end 47 corresponds to an end of the protrusion body 41. Accordingly, it can be stated that the protrusion body 41 includes a first protrusion end 45 (FIG. 4) directly coupled to the second end 38 of the main body 26 and a second protrusion end 47 (FIG. 6) opposite to the first protrusion end 45. The annular body 43 is coupled to the second protrusion end 47 and is disposed around the outer perimeter 62 (e.g., circumference) of the pin 22. In other words, the annular body 43 surrounds at least a portion of the outer surface 60 of the pin 22. Thus, the annular body 43 completely or partly surrounds the pin 22. Accordingly, the protrusion 40 is at least partially disposed around the outer perimeter 62 (e.g., circumference) of the pin 22. In other words, the protrusion 40 at least partially surrounds the pin 22. Specifically, the annular body 43 at least partially surrounds the pin 22.
