Device for reinforcing, sealing or damping a structural element
A device for reinforcing, sealing, or damping a structural element in a motor vehicle including a support which has multiple cells, wherein each cell surrounds a cavity. Each cavity is at least partially delimited by walls in each direction, wherein each cell has an extension in length, height, and width between 5 mm and 100 mm. An outer surface of the support can be connected to the structural element by an adhesive.
1. A device for reinforcing, sealing or damping a structural element in a motor vehicle, the device comprising a support with multiple cells, each cell having multiple walls and a cavity that is surrounded by the multiple walls, each side of the cell being delimited by at least a portion of a wall of the multiple walls,
wherein each cell has an extension in length, height, and width between 5 mm and 100 mm,
an outer surface of the support is configured to be connected to the structural element by an adhesive, and
the multiple walls are integrally formed.
2. The device as claimed in claim 1 , wherein the support has at least four cells.
3. The device as claimed in claim 1 , wherein the walls of the cells close at least 70% of the outer surface of the support.
4. The device as claimed in claim 1 , wherein the cells are arranged in only one layer.
5. The device as claimed in claim 1 , wherein an arrangement and form of the cells is based on an estimated load for the device.
6. The device as claimed in claim 1 , wherein at least one of (i) the cells have different dimensions and (ii) the cells are irregular in form.
7. The device as claimed in claim 1 , wherein a thickness of the walls of the cells is based on an estimated load for the device.
8. The device as claimed in claim 1 , wherein a thickness of the walls of the cells is uneven.
9. The device as claimed in claim 1 , wherein the cells have openings.
10. The device as claimed in claim 9 , wherein the openings are round, oval, rectangular, square or irregular in form.
11. The device as claimed in claim 9 , wherein the cells have at least one opening on at least two walls.
12. The device as claimed in claim 11 , wherein the openings are arranged in walls which are not adjacent to each other.
13. The device as claimed in claim 1 , wherein at least one of (i) the support contains metal, steel, aluminum, magnesium, plastic, fiber-reinforced plastic, organic sheet material, or a combination of the materials, and (ii) all walls of the support are made from the same material.
14. A system of a reinforced, sealed or damped structural element in a motor vehicle, the system comprising:
a structural element;
a support as claimed in claim 1 , wherein the support is arranged in the structural element; and
an adhesive,
wherein the adhesive connects the support and the structural element together.
15. The system as claimed in claim 14 , wherein the adhesive is a non-expandable adhesive or an expandable adhesive.
16. A device for reinforcing, sealing or damping a structural element in a motor vehicle, the device comprising a support with multiple cells, each cell being defined by multiple walls disposed on opposing ends of each of a length, height, and width direction, and having a cavity being surrounded by the multiple walls,
wherein each of the length, height, and width of the cavity extends between 5 mm and 100 mm,
an outer surface of the support is configured to be connected to the structural element by an adhesive, and
the multiple walls are integrally formed.
17. A device for reinforcing, sealing or damping a structural element in a motor vehicle, the device comprising a support with multiple cells, each cell being defined by a cavity being surrounded by multiple walls of the cell, the cavity having no side that is not at least partially enclosed by a wall of the multiple walls of the cell,
wherein each cell has an extension in length, height, and width between 5 mm and 100 mm,
an outer surface of the support is configured to be connected to the structural element by an adhesive, and
the multiple walls are integrally formed.
