A keyboard device is applied to an electronic apparatus and includes a main body, a connection base, a first tilt sensor, a second tilt sensor, and a processor. The connection base is rotatably connected to the main body and configured to detachably be engaged to the electronic apparatus. The first tilt sensor is disposed on the main body and configured to generate first tilt data. The second tilt sensor is disposed on the connection base and configured to generate second tilt data. The processor is electrically connected to the first tilt sensor and the second tilt sensor, and is configured to calculate angle difference data according to the first tilt data and the second tilt data.

User interface apparatuses include a main body having a hinge portion integral with a long-edge at a top edge portion of the main body and a support body having a hinge portion integral with a long-edge at a bottom edge portion of the support body. The hinge portion of the support body is engaged with the hinge portion of the main body for enabling the support body to be pivoted between an in-plane orientation and a deployed orientation relative to the main body. Top and bottom surfaces of the support body each lay one of on and inboard of a reference plane defined by a respective one of a top surface and a bottom surface of the main body when the support body is in the in-plane orientation with respect to the main body. An overall thickness of the main body and the support body is preferably about the same.

A keyboard device according to one embodiment includes: a box-shape body, comprising a first side-wall and a second side-wall arranged opposite to and is pivotably openable relative to the first side-wall; a support assembly, configured to be connected detachably to the first side-wall of the box-shape body such that the box-shape body is adapted to support the electronic apparatus; and a flexible membrane keyboard which is connected with an internal surface of the second side-wall of the box-shape body and switchable between an unfolded condition in which the flexible membrane keyboard functions as a keyboard of the electronic apparatus and a folded condition in which the flexible membrane keyboard is received within the box-shape body. The keyboard device of the embodiments of the disclosure may function as both a keyboard for the electronic device and a support, and is provided with a limited size so as to facilitate portability thereof.

Examples apparatus, systems, articles of manufacture and methods to adjust a keyboard position are disclosed. An example keyboard position adjustment system includes a keyboard orientation detector to determine a first keyboard position of a keyboard and/or a hand position detector to determine a hand position near the keyboard. The example system also includes an adjuster to move the keyboard to a second keyboard position based on the first keyboard position and/or the hand position.

An adjustable keyboard having a number of keys is formed in at least two segments which are mutually movable relative-to one another using a hinge or joint. Each of the segments of the keyboard has mounted thereon some of the keys. The adjustable nature of the keyboard reduces stress and discomfort to the user by reducing contortion to the user's wrists. More particularly, discomfort to the user caused by pronation of the wrists and/or ulnar deviation of the wrists is reduced. The hinge or joint is in the form of a ball and socket-type joint with a locking mechanism, which preferably includes a pivoted handle, in the form of a lever, used for locking and unlocking the hinge or joint. The surface of at least one of the ball and socket of the joint define a plurality of recesses or a plurality of projections, to provide increased resistance to joint movement.

A mechanical keyboard with reduced number of keys includes many mechanical keys which are divided into a function section and an alphanumeric section disposed at one side of the function section. Each mechanical key has a keycap. The keycap has a light-transmitting character symbol on a top surface thereof. At least one mechanical key is a self-defined key in the function section or the alphanumeric section. Each keycap of the self-defined key has a top wall and a side wall facing a user. The top wall and the side wall respectively have a light-transmitting character symbol. Each self-defined key has a first lighting module and a second lighting module which are alternatively activated to light. The first lighting module corresponds to the top wall of the self-defined key. The second lighting module corresponds to the side wall of the self-defined key.

A keyboard set may be provided on chair armrests. The keyboard set includes a left keyboard, a right keyboard, a first detachable support, a second detachable support, and two multidirectional angle adjusting mechanisms. Each of the left keyboard and the right keyboard includes a plurality of keys. One end of the first detachable support is combined with the left keyboard, and one end of the second detachable support is combined with the right keyboard. The two multidirectional angle adjusting mechanisms are respectively provided between the first detachable support and the left keyboard, and between the second detachable support and the right keyboard.

A stand includes: a frame body has an opening portion and a supporting portion is around the opening portion and supports a rear surface of the electronic apparatus; a leg portion is rotatably connected to the supporting portion inside the opening portion via a torque hinge and is capable of moving between a first angular position, at which the leg portion is accommodated at least inside the opening portion, and a second angular position, at which the leg portion protrudes from the supporting portion by rotating in a first direction from the first angular position; a first magnet that is provided on an inside surface of the supporting portion to face the opening portion; and a second magnet that is provided on an outside surface of the leg portion to face the inside surface of the supporting portion and that is capable of being attracted to the first magnet.

A bracket and an electronic device are provided. The bracket includes a support mechanism and a keyboard. The support mechanism includes a fixed plate and a support seat rotatably connected to the fixed plate. The fixed plate is provided with a fixed surface and a mounting surface. The fixed surface and the mounting surface are respectively located on both sides of the fixed plate which are opposite each other, and the fixed surface can be detachably connected to the electronic equipment. The keyboard is connected to the support seat and is used for inputting data to the electronic device. The electronic equipment such as tablet computer or mobile phone can be detachably set on the fixed surface to support the electronic equipment. Users can input data to the electronic equipment through the operation keyboard without touching the screen of the electronic equipment, which is convenient for users to operate.

A keyboard includes: a recessed portion formed along a rear edge and open from a rear surface to a bottom surface; and a magnet located at a recessed portion top surface. A stand includes: a frame body that abuts a rear surface of an electronic apparatus; a plate connected to part of the frame body via a torque hinge, and having a distal edge abutting a placement surface in a state of being open relative to a frame surface of the frame body; a band portion connected to a long-side frame of the frame body along the long-side frame, and having a width that allows side surfaces of the electronic apparatus to be supported; and a bar of an iron material located along a distal edge of the band portion.
