摘要:
A method for executing mechanical overload protection to prevent commanding a control signal to a linear actuator that may mechanically overload the linear actuator when an overload condition of the linear actuator is detected, the linear actuator utilized for controlling a movable element associated with the linear actuator responsive to the control signal, includes monitoring an overload condition based on position change of the movable element associated with the linear actuator during an integration period and excess energy during the integration period, de-energizing the linear actuator when an overload condition has been detected, monitoring an overload retry counter based on the number of cycles the overload condition is detected, comparing the overload retry counter to an overload retry threshold, an reenergizing the linear actuator when the overload retry counter is less than the overload retry threshold and maintaining de-energizing of the linear actuator when the overload retry counter is at least the overload retry threshold.
摘要:
A vent assembly is disposed within an interior space of a vehicle for opening and closing fluid communication between the interior space and an exterior of the vehicle. The vent assembly includes a housing defining a plurality of openings and a plurality of vanes disposed in the openings. An actuator mechanism moves the vanes between an open position and a closed position, and includes a shaped memory alloy (SMA) member for actuating the vanes between the open and closed positions. The SMA member is activated when a hatch of the vehicle is open to move the vanes into the open position and thereby open fluid communication between the interior space and the exterior to alleviate excessive air pressure buildup during closure of the hatch.

A pressure relief valve includes a housing and vane that is movable to one of an open position and a closed position. A linear actuator mechanically couples between the movable vane and the housing. The linear actuator is a wire device fabricated from a shape memory alloy. An actuable latching system is configured to retain the movable vane in one of the open position and the closed position for an indeterminate time period.

An ornamental wheel insert utilizing a snap-fit attachment to a wheel. In a first embodiment, fingers carrying bosses are attached to an insert body, wherein when the insert body is seated the bosses snappingly engage a boss abutment of the wheel. In a second embodiment, a snap ring snappingly engages the insert body from the inside of the wheel to thereby securely seat the insert body at the wheel.

Disclosed is a rotatably-mountable bumper configured for rotatably and ergonomically mounting to a mounting member for cushioning the contact between the mounting member and a potentially interfering member. The bumper transmits reactive forces between two members, such as a vehicle hood and grille, if portions of one member over travels. A fastening member on the bumper rotatably engages an aperture on the mounting member to secure the bumper to the mounting member. A registration member on the bumper retentively holds the bumper in rotatably-mounted engagement with the mounting member.
