Disclosed is a hinge module including a hinge structure having a first sub-hinge structure including a first center bracket and a first hinge bracket that rotates through a specified angle in a first direction and a second sub-hinge structure including a second center bracket and a second hinge bracket that rotates through a specified angle in an opposite direction to the first direction. The first hinge bracket and the second hinge bracket are separated from each other and are disposed between the first center bracket and the second center bracket, and hinge motion of the first sub-hinge structure is performed independently of hinge motion of the second sub-hinge structure. The hinge module and a foldable display device including the hinge module suppress a phenomenon in which the hinge module is opened when the housing structures are twisted, thereby preventing damage to the foldable display device.

A foldable display device includes a hinge, a support plate connected to opposite ends of the hinge and a display panel module disposed on the support plate. The hinge includes a rotation axis module having a rotation axis. A first slider is connected to the rotation axis and includes a first guide line. A second slider is connected to the support plate and includes a second guide line. A link arm includes a link arm body. The link arm body has a link arm rotation axis disposed at a first end of the link arm body and a link arm pin hole disposed at a second end of the link arm body. A link arm pin is configured to extend through the link arm pin hole, the first guide line and the second guide line.

Provided is a refrigerator. The refrigerator is characterized by enabling at least a part of a refrigerator door to be selectively transparent by a user's operation, such that the user sees through an inside of the refrigerator while the refrigerator door is closed.

A combination door guide and protector can be used to safely and easily attach or remove vehicle doors. A set of two guides can be used for each door. Each guide can include a forward curved portion and a second curved portion that extend outwardly away from a body and form a groove. Each guide also includes a crenellated void. A body can connect the two guides and can extend away from each side of the curved portions to provide protection to the vehicle frame and body. The crenellated voids can be placed on top of weldments of hinge pin receivers located on the vehicle body frame. Hinge pin housings on the vehicle door can be slid within the groove until hinge pins on the door engage with the hinge pin receivers. The combination device makes it easier to align the hinge pins with hinge pin receivers.

A security door assembly is disclosed including a hinge assembly having a first hinge plate having at least a first hinge pin receptacle extending from the first hinge plate, and a second hinge plate having at least a second hinge pin receptacle extending from the second hinge plate. A hinge pin is removably received in a longitudinal direction within the first and second hinge pin receptacles such that the first and second hinge plates are pivotal with respect to one another via the hinge pin. The hinge assembly includes a bearing assembly disposed between the hinge pin and one of the first or second hinge pin receptacles, and a retention member removably extending in a first lateral direction into one of the first or second hinge pin receptacles and engaging the hinge pin.

An embodiment system for illuminating a charging port of an electric vehicle is provided. The charging port is provided in a vehicle body for supplying electrical power to a vehicle driving battery, and the system includes a charging port door configured to open and close the charging port, and a lamp device disposed on the charging port door and configured to illuminate the charging port.

A foldable screen and a shower room are provided. The foldable screen includes a transmission gear mechanism and a plurality of panel bodies arranged in sequence. End portions of two adjacent sides of two adjacent panel bodies enclose to form a mounting opening into which the transmission gear mechanism is installed for realizing folding and unfolding of the plurality of panel bodies. The transmission gear mechanism includes a housing having a receiving cavity therein, the housing being installed in the mounting opening; a first gear located in the receiving cavity and installed on one of the two adjacent panel bodies; and a second gear meshed with the first gear, the second gear being located in the receiving cavity and installed on the other of the two adjacent panel bodies.

A hinge includes a base frame unit and two rotatable axle units. The base frame unit includes a base seat and a protective cover. The base seat has two guideways having upper and lower segments, and two shaft sliding slots. The protective cover has a base wall and two pivot pins. Each axle unit rotatably extends through the base seat, and includes a hinge shaft rotatably extending through the shaft sliding slot, a first rotary member non-rotatably fitted to the hinge shaft, a second rotary member connected with the first rotary member, and a support bracket non-rotatably fitted to the hinge shaft. The first rotary member has a guide key slidably engaged in the guideway. The second rotary member is pivoted to the pivot pin and has an engaging hole for receiving the guide key.

Provided is a refrigerator. The refrigerator is characterized by enabling at least a part of a refrigerator door to be selectively transparent by a user's operation, such that the user sees through an inside of the refrigerator while the refrigerator door is closed.

A door hinge sized and configured to cover at least one door hinge of a vehicle includes a cover body that at least partially surrounds the at least one door hinge when connected to a pillar of the vehicle. The cover body includes fastening locations that are located to align with fastening location on the pillar for fastening the hinge cover in place.
