Reinforcements provide structural support without a significant increase in cost and weight. For instance, reinforcements may be used in automobiles to reinforce cavities formed by various parts of the automobile such as a pillar, bumper, etc. To properly transfer loads from one side of the structure to the other, the reinforcement has features that generally match the inner surfaces of the cavity in which the reinforcement is placed. However, those features in reinforcements are difficult and expensive to manufacture. Accordingly, a reinforcement is needed that provides the same or additional structural and/or acoustic support within a cavity with less complexity than previous reinforcements.
Accordingly, one object of the invention is to provide a reinforcement that provides the same or additional structural and/or acoustic support within a cavity with less complexity than previous reinforcements.
The advantages of the invention can be seen, inter alia, in the fact that a reinforcement includes a carrier having an array of cylinders. The carrier is configured to be disposed in a structure, and each of the cylinders defines an axis aligned with a structural load applied to the structure. The axes defined by the cylinders are parallel to one another and define a plane. A bonding material is disposed on the carrier and is configured to connect the carrier to the structure. Further advantageous embodiments of the invention emerge from the dependent claims.
An exemplary reinforcement that transfers a load from one part of a structure to another part of a structure includes a carrier having an array of cylinders. Each cylinder in the array extends in a direction that is parallel to the other carriers, and the cylinders are generally aligned in a plane. That is, each cylinder defines an axis and the axes defined by the cylinders are parallel to one another and define a plane. The carrier is configured to be disposed in a structure, and at least one of the cylinders defines an axis aligned with a structural load that may be applied to the structure. A bonding material is disposed on the carrier and is used to connect the carrier to the structure. A reinforcement having this arrangement is able to transfer a structural load between sidewalls of the structure with a sufficient performance to weight ratio but without complex manufacturing complexity and costs.
As illustrated in
The carrier 105 may include one or more cylinders 120 that are disposed within a space 125 defined by the structure 115. In one exemplary approach, the cylinders 120 are integrally formed with one another. Alternatively, the cylinders 120 may be formed separately and attached to one another using an adhesive to mechanical fastener. The cylinders 120 are generally aligned in a plane. That is, each cylinder 120 defines an axis A extending, for instance, through a center of the cylinder 120, and the axes A of the cylinders 120 are generally parallel to one another.
The cylinder 120 may be slightly smaller than the space 125 defined by the structure 115, and one or both ends of the cylinder 120 may be disposed on the structure 115. The cylinder 120 is generally hollow and defines the axis A near the center of the cylinder 120. The cylinder 120 is configured to be placed within the structure 115 so that the axis A defined by the cylinder 120 is generally aligned with forces F applied to one or both sides of the structure 115. This allows the cylinder 120 to distribute forces F applied to one side of the structure 115. That is, the forces F applied to one side of the structure 115 are able to travel through the cylinder 120 to the other side of the structure 115.
The cylinder 120 has a length L that is slightly smaller than a width W of the space 125. In one exemplary approach, the cylinder 120 may be approximately 2-8 mm smaller than the width W of the structure 115. The reinforcement 100 may be disposed within any space 125 defined by a structure 115, regardless of size or shape of the space 125. Therefore, when multiple cylinders 120 are used in the carrier 105, some of the cylinders 120 may be different lengths L than other cylinders 120. For example, if the space 125 defined by the structure 115 is tapered, the cylinders 120 may have appropriate lengths L to fit within the tapered space 125. Moreover, to accommodate a tapered shape, the ends of the cylinder 120 need not be parallel to one another. That is, one end of the cylinder 120 may define one plane and another end of the carrier 105 may define a transverse plane. Further, the carrier 105 may include any number of cylinders 120. For instance,
The bonding material 110 is used to attach the carrier 105 to the structure 115. The bonding material 110 may be disposed on the carrier 105. For instance, the bonding material 110 illustrated in
The structure 115 may include any object that defines the space 125. For instance, the structure 115 may include two sidewalls 130 that are spaced from one another such that the space 125 is defined between them. The sidewalls 130 may at least partially extend in a parallel direction. One or both sidewalls 130 may define openings (not shown) for receiving fixation elements 135 (see
The fixation elements 135 may be used to fasten the carrier 105 to the sidewalls 130 of the structure 115. For instance, the structure 115 may define openings (not shown) that are configured to receive the fixation elements 135. The fixation elements 135 may be biased so that they hold the carrier 105 in place relative to the structure 115 when the fixation elements 135 are placed in the openings. For instance, the fixation element 135 may include a clip that contracts while being pushed into the opening and expands after the clip has been placed into the hole. Each fixation element 135 may be disposed on one cylinder 120, or alternatively, may be disposed between two cylinders 120.
With reference to
One or more of the cylinders 120 may define gaps 140, for example, about their peripheries, that allow the bonding material 110 disposed within one cylinder 120 to connect to the bonding material 110 within another cylinder 120. Therefore, the gaps 140 provide a mechanical linkage of the bonding material 110 between cylinders 120 at least until the cylinder 120 is disposed in the space 125.
