The present invention relates to an anti-pinch sensor for a door of a vehicle. In particular, the present invention is directed to an easy install pinch sensor for a horizontal or vertical exterior body closure.
Anti-pinch sensors are often used by automotive OEM's on the sides of a liftgate as a due care type safety item. Such sensors are used on liftgate doors that have a power actuation system, to stop or reverse a door if there is an obstacle in the way. These anti-pinch sensors create additional parts, additional costs, create assembly complexity, packaging concerns, appearance concerns, and quality concerns. Integrating the mounting surface of the anti-pinch sensor to the liftgate inner panel is an improvement over a conventional molded carrier but continuing to use two-sided sticky tape with adhesion promotor and mechanical fasteners as a primary attachment is not the most efficient.
Thus, it is an object of the present invention to reduce complexity, reduce cost, reduce possibility of poor assembly, improve quality, reduce assembly time, reduce weight, improve appearance when providing for an anti-pinch sensor in a vehicle liftgate and any other closure panel.
A liftgate or other closure panel assembly for a vehicle having an anti-pinch sensor attached at an outer peripheral area of the liftgate is provided. The liftgate includes an outwardly extending flange portion. An anti-pinch sensor mount including a U-shaped cross section which is adapted to fit over and secure to the outwardly extending flange portion. An anti-pinch sensor is attached to the mount for sensing an interference in opening or closing of the liftgate and reversing the opening or closing of the liftgate.
This invention allows for a small easy to mold flange on the inner panel, does not require adhesion promotor, or two-sided sticky tape, has better self-locating features, has better performance and durability for real life testing such as car wash brushes.
Creating a pocket in the extrusion portion of the anti-pinch sensor that allows for easy assembly and locating onto a simple flange.
The present invention provides an open section that allows loading on a flange and is integrated into the anti-pinch sensor extrusion without adding extra components.
The invention provides the anti-pinch sensor operable to attach to the outer peripheral area of the closure panel. This invention allows for the easy to form flange on a panel, the anti-pinch sensor installed to the flange.
The invention provides an easy install anti-pinch sensor for horizontal or vertical thermoplastic exterior body closures in accordance with aspects of the present invention.
Further areas of applicability of the present invention will become apparent from the detailed description provided hereinafter. It should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.
The present invention will become more fully understood from the detailed description and the accompanying drawings, wherein:
The following description of the preferred embodiment(s) is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses.
Referring to
In accordance with the present invention there is provided a liftgate for a vehicle generally shown at 10. The liftgate 10 has an anti-pinch sensor generally shown at 12 attached at an outer peripheral area of the liftgate 10. The liftgate 10 includes an outer show surface panel 14 and an inner panel 16. The inner panel 16 includes reinforcement structure 18. Attachment structure 20, 22 attaches the inner panel 16 to outer panel 14. The inner panel 16 is preferably formed of a filled thermoplastic and includes an outwardly extending flange portion 24.
Anti-pinch sensor 12 includes an outer pinch sensor bulb portion 26 and a pinch sensor mount 28. The mount portion 28 including a U-shaped cross section formed by two outer legs 30 and 32 connected by an inner wall 34 this mount is designed to fit over and secure to the outwardly extending flange portion 24. Preferably the mount portion 28 is adapted for press fitting onto the flange 24. Preferably the anti-pinch sensor bulb 26 and the pinch sensor mount 28 are an elongated one-piece extrusion. Typically, the mount portion 28 is mechanically attached and is of a durometer that will provide enough compression to hold onto the flange 24. However, mount 28 can also be glued to the flange 24 with butyl adhesives or the like if further securement is necessary. Mechanical fasteners, staples and/or crimping of the flange are also used in other embodiments. Additionally, the flange 24 in other embodiments includes a stepped surface or openings which can promote securement of the mount portion 28 onto the flange.
The anti-pinch sensor bulb 26 is attached to the mount portion for sensing an interference in opening or closing of the liftgate and reversing the opening or closing of the liftgate thus the anti-pinch sensor bulb portion 26 is of a softer durometer than the mount to provide proper compression for sensing of an object which interferes with opening or closing of the liftgate.
The anti-pinch sensor 12 is operably adaptable for suitably connecting to at least one panel of any closure panels 10, e.g., liftgate, hood, frunk, forward storage compartment, frunk cover, forward storage cover, electric vehicle's front storage area or cover, door, sliding door, side door, hinged door, rear door, storage lid, tailgate, decklid, trunk, rear storage compartment, trunk cover, decklid cover, storage compartment cover, etc., operably adapted to connect to a vehicle.

The closure panel 10 includes at least one of the anti-pinch sensors 12 attached adjacent at least one outer peripheral area, indicated generally at 40, of the closure panel 10. According to aspects of the present invention, at least two of the anti-pinch sensors 12, 12 on at least two outer peripheral areas 40, 40, respectively.
The anti-pinch sensor 12 includes an outer pinch sensor bulb portion 26 and a pinch sensor mount 28 (e.g., see
The anti-pinch sensor bulb 26 is attached to the mount portion for sensing an interference in opening or closing of the closure panel 10. The closure panel 10 is operably adapted for reversing the opening or closing of the closure panel 10 (e.g., by an operably coupled predetermined device indicated at 38 in a predetermined location, actuator, motor, or other suitable device or mechanism operably adapted for automatically reversing opening/closing of the closure panel 10 a predetermined amount) if an interference is sensed. Thus, the anti-pinch sensor bulb portion 26 is of a predetermined softer durometer than the pinch sensor mount 28 to provide proper compression for sensing of an object which interferes with opening or closing of the closure panel 10.
The anti-pinch sensor 12 bulb 26 and pinch sensor mount 24 are preferably an integral extrusion. Either the first or second panel 14 or 16, e.g., inner panel 16, is preferably a molded panel having an integrally molded outer flange 24 for engagement of the mount portion of the anti-pinch sensor 12.
