A display device according to an embodiment of the present disclosure may include a base, a stand bar extending upward from the base in a vertical direction, and a head having a display on a front side and having a pair of long sides and a pair of short sides on a peripheral portion, the head being pivotable between a landscape mode in which the long side is in a horizontal state and a portrait mode in which the long side is in a vertical state, wherein the head may include a processor configured to determine whether a rotation unlock condition of the head is satisfied, and when the rotation unlock condition of the head is satisfied, rotate the head about a rotation axis as external force is applied to the head.

An angle adjustment apparatus, a sensor assembly, and a driverless vehicle, in the field of mechanical technologies. The angle adjustment apparatus includes first and second mounting brackets, a crisscross shaft, and first and second locking rings, where the crisscross shaft includes first and second adjustment shafts crossing each other, the first adjustment shaft is rotatably connected to the first mounting bracket, and the second adjustment shaft is rotatably connected to the second mounting bracket; the first locking ring is fixed to a fixed mounting bracket, and the second locking ring is fixed to a movable mounting bracket; one end of the first adjustment shaft close to the first locking ring is provided with first and second elastic locking pieces; and one end of the second adjustment shaft close to the second locking ring is provided with third and fourth elastic locking pieces.

An attachment mechanism for mounting an electronic device to a surface including a mounting plate configured to attach to the surface, the mounting plate having at least one projection, and a base configured to releasably couple to the mounting plate. The base may include a first biasing member, and a first arm pivotably coupled to the base and biased toward a first direction by the first biasing member, the first arm configured to interlock with the at least one projection when the base is coupled to the mounting plate. The base may further include a release mechanism coupled to the first arm such that actuation of the release mechanism when the base is coupled to the mounting plate in a secured engagement causes movement of the first arm in a second direction to disengage the first arm from the at least one projection to enable detachment of the base from the mounting plate.

A display apparatus includes a display module displaying an image, a support assembly facing toward the display module, a driver installed on the support assembly for supplying power to rotate the display module, a linearly-movable assembly connected to the driver to receive power therefrom and configured to perform a linear movement in a first direction along the support assembly, and a rotation guiding mechanism that connects the linearly-movable assembly to the display module, and guides rotation of the display module using the movement of the linearly-movable assembly.

A supporting device for supporting a display is provided. The supporting device includes an upright, a bearing slider, an actuating module, a driving module, and a control module. The upright includes a column body and a receiving space. The bearing slider is slidably disposed in the receiving space. The actuating module includes a screw rod and a screwing element, the screw rod is pivoted to the upright along a first axis and inserted to the screwing element, and the screwing element is disposed on the bearing slider and screws with the screw rod. The driving module is connected to the actuating module and drives the screw rod to rotate about the first axis. The control module controls the driving module to drive the screw rod to rotate to make the screwing element and the bearing slider move between a highest position and a lowest position along the first axis.

A supporting device for carrying a display is provided and includes: a support upright; a protruding neck provided on the support upright; and a carrying board unit being able to be detachably arranged on the protruding neck and used for carrying the display. The carrying board unit includes a quick-release fixing member detachably arranged on the protruding neck.

A supporting device is provided for carrying a display and includes: an upright column; a protruding neck arranged on the upright column; a spindle rod unit with a main spindle rod fixed on the protruding neck along a second axis; a carrying board unit pivoted on the main spindle rod, used for carrying the display and having an upper half area and a lower half area relative to a gravity direction and the second axis; and an elastic element set including a first elastic element with one end arranged on the protruding neck and the other end arranged on one of the upper half area and the lower half area, where the first elastic element constantly provides a first elastic force, and the first elastic force enables the carrying board unit to rotate about the second axis as an axis.

A display apparatus is provided. The display apparatus includes: a display panel; a support bracket coupled to the display panel; a support arm coupled to the support bracket and supporting the display panel, wherein the support arm is configured to rotate between a first and second orientations; and a support stand supporting the support arm and defining a limiting groove, the support stand being configured to allow the support arm to move along a vertical direction. The support arm includes a limiting link configured to be in a first position that is offset from the limiting groove when the display panel is in the first orientation and a second position extending into the limiting groove when the display panel is in the second orientation.
