A license plate cover system includes a base plate defining a first surface configured to face a vehicle. A second surface of the base plate is configured to face away from the vehicle. A side surface of the base plate connects the first surface with the second surface. The base plate includes protrusions extending from the side surface. A cover plate defines a first surface configured to face the second surface of the base plate. A second surface of the cover plate is configured to face away from the base plate. An inner side surface connects the first surface of the cover plate with the second surface of the cover plate. The cover plate includes recesses configured to receive the protrusions therein. The cover plate is configured to be removably coupled with base plate by securing the protrusions in corresponding recesses of the plurality of recesses.

A positioning device for fixing a vehicle registration plate in an affix hole of a vehicle contains: a connection member, at least one fitting sleeve, a flexible bushing, an operation sheath, and a screw rod. The connection member includes an arcuate section and two flat sections, and the arcuate section has an elongated orifice. Each of the at least one fitting sleeve includes a first through orifice, a first protrusion, and an indentation. The flexible bushing includes a peripheral rib, a second through orifice, multiple slits, and a second protrusion. The operation sheath includes a taper, multiple retaining ribs, and a threaded orifice. The screw rod inserts through the first through orifice of each fitting sleeve and the second through orifice of the flexible bushing to screw with the threaded orifice of the operation sheath, and positioned on the screw rod are a washer and a nut.

Adjustable license plate brackets for vehicles comprising a first bracket element that is secured to a vehicle; a second bracket element having an upper end to be connected to a license plate and a lower end disposed upon the first end of the first bracket element; and a third bracket element having an upper end to be connected to a license plate and a lower end disposed upon the second end of the first bracket element. The second bracket element and the third bracket element are configured to be connected to the first bracket element at a plurality of positions, implemented using an elongated aperture with a plurality of notches into which a bracket element connector can be inserted, respective so that a distance between the upper ends of the second and the third bracket elements varies to accommodate license plates with different sizes.

This invention discloses a device and method for mounting and changeably displaying visual communications, including messages, logos, advertisement, public service announcements or indicia, on a vehicle. It incorporates a frame mounted on a license plate, optionally within the license plate recess at the front or rear of a vehicle, and utilizes panels that are continuous with or removeably attached to a central component framing the license plate in order to optimize visual appeal, minimize aerodynamic drag, and reduce or eliminate potential clearance issues. A removeably attachable panel configuration allows for panels to be mounted on one or both lateral sides, providing a means for customization based on a vehicle's exterior design or user preference.

There is provided an adapter plate assembly for mounting a license plate to a vehicle. The assembly includes an adapter plate with a backing portion shaped to couple with and inhibit bending of the license plate. The assembly includes a resilient member having a lower portion connectable with the adapter plate and an upper portion for coupling to the vehicle. The resilient member is configured to enable the license plate to move slightly forward and rearward.

Digital license plates having a range of physical and digital antitheft features are disclosed. Disengagement of the digital license plate from the vehicle triggers at least one of a wireless theft communication signal and the internal theft status indicator. Input of security credentials can prevent triggering the internal theft status indicator and disablement of the digital license plate.

A digital license plate can support methods for assuring preservation and user authorized electronic access to vehicle relevant information or vehicle history. An external user interface to the digital license plate is configured to allow a user to provide user authorization to control release of sensor and other data from the digital license plate.

A vehicle messaging system is provided. The vehicle messaging system includes a message panel configured to join the vehicle. The message panel includes a secondary power source in addition to the primary power source provided by the vehicle. The message panel includes a thermostat, a heating portion, and a cooling portion that together maintain the message panel at a pre-determined temperature. The message panel also includes alert systems, protection panels, and an image capturing device.

A license plate holder includes a frame defining a central opening to permit display of indicia on license plate display region(s) of a license plate and defining frame display region(s) adjacent the central opening. A transmissive substrate includes one or more connectors to removably connect the transmissive substrate to a license plate base. In an assembled state with the transmissive substrate removably connected to the license plate base via the connector(s) and the frame interposed between the transmissive substrate and the license plate base, a central region of the transmissive substrate is positioned in front of the central opening and the license plate display region(s) and a peripheral region of the transmissive substrate is positioned in front of the frame display region(s).
