Abstract

A collision sensor module configured to be attached to a surface of a vehicle. The module includes a collision sensor circuit board configured to detect acceleration indicative of a vehicle collision event. The exterior of the module is defined by a housing that includes a rigid part and a flexible part. The rigid part is configured to define a wing portion for attaching the rigid part to the surface, provide an underside surface of the rigid part to couple the collision sensor circuit board to the surface in a manner effective for the circuit board to detect when the vehicle is involved in a collision event. The flexible part is configured to sealingly contact the rigid part and the collision sensor circuit board in a manner effective to seal the protective cavity when the rigid part is attached to the surface and thereby protect the collision sensor circuit board.

Claims

1. A collision sensor housing configured to be attached to a surface of a vehicle, said housing comprising:

a rigid part configured to define a wing portion for attaching the rigid part to the surface, said rigid part further configured to define a protective cavity between a top portion of the rigid part and the surface, wherein the top portion is separated from the surface by the wing portion, wherein said protective cavity is configured to receive a collision sensor circuit board; and

a flexible part configured to sealingly contact the rigid part and the collision sensor circuit board in a manner effective to seal the protective cavity when the rigid part is attached to the surface and thereby protect the collision sensor circuit board, wherein the flexible part is formed of elastomeric material being one of silicone rubber, neoprene, and ethylene propylene diene Monomer (EPDM), and characterized as having a durometer of 65-85 Shore A.

2. The housing in accordance with claim 1, wherein the collision sensor circuit board is coupled to the surface via the rigid part in a manner effective for the collision sensor circuit board to detect when the vehicle is involved in a collision event.

3. The housing in accordance with claim 2, wherein the rigid part defines an underside of the top portion facing the surface, and the collision sensor circuit board is attached to the underside.

4. The housing in accordance with claim 1, wherein the wing portion includes a first wing portion configured to couple a first edge of the top portion to the surface, and a second wing portion configured to couple a second edge of the top portion opposite the first edge to the surface, whereby the top portion, the first wing portion, and the second wing portion are arranged to define a first opening and a second opening along opposite edges of the top portion between the first edge and the second edge.

5. The housing in accordance with claim 1, wherein the rigid part is formed of aluminum by way of extrusion.

6. The housing in accordance with claim 1, wherein the flexible part includes a member configured to engage with a receiving hole in the collision sensor circuit board in a manner effective to hold the flexible part proximate to the collision sensor circuit board when the rigid part is not attached to the surface.

7. A collision sensor module configured to be attached to a surface of a vehicle, said module comprising:

a collision sensor circuit board configured to detect acceleration indicative of a vehicle collision event;

a rigid part configured to define a wing portion for attaching the rigid part to the surface, said rigid part further configured to define a protective cavity between a top portion of the rigid part and the surface, wherein the top portion is separated from the surface by the wing portion, wherein said protective cavity is configured to receive the collision sensor circuit board and couple said collision sensor circuit board to the surface in a manner effective for the collision sensor circuit board to detect when the vehicle is involved in a collision event; and

a flexible part configured to sealingly contact the rigid part and the collision sensor circuit board in a manner effective to seal the protective cavity when the rigid part is attached to the surface and thereby protect the collision sensor circuit board, wherein the flexible part is formed of elastomeric material being one of silicone rubber, neoprene, and ethylene propylene diene Monomer (EPDM), and characterized as having a durometer of 65-85 Shore A.

8. The module in accordance with claim 7, wherein the wing portion includes a first wing portion configured to couple a first edge of the top portion to the surface, and a second wing portion configured to couple a second edge of the top portion opposite the first edge to the surface, whereby the top portion, the first wing portion, and the second wing portion are arranged to define a first opening and a second opening along opposite edges of the top portion between the first edge and the second edge.

9. The module in accordance with claim 7, wherein the flexible part includes a member configured to engage with a receiving hole in the collision sensor circuit board in a manner effective to hold the flexible part proximate to the collision sensor circuit board when the rigid part is not attached to the surface.

10. The module in accordance with claim 7, wherein the collision sensor circuit board includes a connector header configured so one or more connector pins are exposed and available for contact with a connector from outside the module, and the flexible part is configured to sealingly contact a perimeter surface of the connector header.
