  • Patent number: 11987306
    Abstract: A system for modifying the range capability of an electric vehicle includes a vehicle body having a front axle and a rear module secured to the vehicle body. The rear module includes a rear axle and the rear module is detachable from the vehicle body and replaceable with another rear module. The rear modules may include different range extension capabilities. The rear modules may include a battery or a combustion engine that may supplement the standard battery and electric motor of the vehicle. A pair of laterally translatable pins of the rear module may be moveable into and out of engagement with the vehicle body. The rear module may also include vertically extending posts that engage with the vehicle body. The vehicle body may be raised to disengage the posts from the vehicle body.

  • Publication number: 20240093538
    Abstract: A vehicle door system includes doors with a door module attached to a hinge module, which is attached to the vehicle body. The door module includes a latch mechanism configured to engage a striker pin of the vehicle body, with a pawl that pivots to accommodate a misalignment with the striker pin during a door closing operation, with the latch mechanism shifting following engagement with the striker pin. A door check mechanism includes a permanent magnet and a steel plate. Activation of the permanent magnet shifts the steel plate from a closed position to an open position permitting the hinge module to move from a locked position. An interface between doors includes a primary and secondary seal each having a constant cross section, with filler pieces disposed between the door and the secondary seal along a portion of the interface.

  • Patent number: 11807080
    Abstract: A vehicle door system includes a door with a door module and a hinge module. The hinge module is attached to the vehicle body. The door module is attached to the hinge module. The hinge module includes a hinge bracket attached to the vehicle body, and a pair of arms extending from the hinge bracket that can pivot relative to the hinge bracket and a cross brace attached at the ends of the arms. The door module attaches to the cross brace. The door module moves along with the cross brace, which moves along with the arms as they pivot relative to the hinge bracket. The door module includes a latch mechanism at a bottom edge, with the latch mechanism engaging with the vehicle body. A lateral edge of the door may seal against a lateral edge of the second door without a latch interface.

  • Publication number: 20220017019
    Abstract: A system for modifying the structure of a unibody vehicle includes a vehicle body having a unibody construction and a first module attached to the vehicle body. The first module is removable from the vehicle body and replaceable with a second module having a different size and/or functionality. A rear portion of the first module may be removed from the first module and attached to the second module. The first module may be a stock cargo module, and the second module may be an aftermarket module. The rear portion may be a stock tail tamp and/or sensor module. The rear portion may be removed before or after removing the first module from the vehicle body, and may be attached to the second module before or after attaching the second module to the vehicle body.

  • Publication number: 20190301231
    Abstract: A system for opening and closing a closure of a vehicle, such as a door or a tailgate, is provided. The system includes a motor such as an electric motor which may be coupled to the closure via an output linkage, with the output linkage mechanically coupled to the closure and operable to move the closure between a closed position and an open position. The output linkage may include a driven pulley which may be coupled to the motor. The output linkage may include a driven pulley and a cable. The output linkage may include a leadscrew threadedly engaging a nut. A high-bandwidth MR clutch having a high dynamic response may selectively couple the motor with the closure to provide a haptic or tactile feedback to a user interacting with the closure as it is opened or closed.

  • Patent number: 9561766
    Abstract: A bumper assembly includes a bumper beam for absorbing an impact of a vehicle and a crash box attached to the bumper beam and extending along an axis A. A mounting plate is attached to the crash box and defines at least one lateral slot extending laterally along the mounting plate in spaced and perpendicular relationship to the axis A. A fastener extends through the lateral slot for mating with a mounting surface of the vehicle frame to establish a secured position of the bumper assembly. The fastener includes a shoulder disposed in abutting relationship with the mounting surface in the secured position to dispose the mounting plate and the mounting surface in spaced relationship to one another for allowing the fastener to slide laterally along the lateral slot during a vehicle impact to reduce the transfer of lateral impact forces from the bumper assembly to the vehicle frame.
