The application provides a bight button structure, this bight button structure can set up in the bight of display frame, bight button structure includes fixed bolster, circuit board and key cap from interior to exterior in proper order, wherein: the key cap is connected with the circuit board through a rebound member and is provided with conductive contacts so that the circuit board can be conducted when the key cap is pressed down; the key cap has a right triangle cross-sectional shape to accommodate the mounting space of the corner; and the key cap can be exposed to the outside through a through hole arranged on the front surface of the display frame so as to be pressed by a user.

One end of the fixed bracket is used for installing the circuit board and the keycap; the other end of the fixed support is arranged on the display frame through a corner connecting piece arranged at the corner.

Preferably, the fixing bracket is made of hard plastic or metal material to improve the stability of the corner key structure.

Preferably, the resilient member is a silica gel pad or spring to ensure a good resilient effect after the key cap is pressed and to provide tactile feedback to the user.

Preferably, the circuit board includes a microprocessor for receiving and interpreting the electrical signal generated by the key cap depression.

The application also discloses a display frame, this display frame has at least one bight that is right angle shape, this bight can be used for installing bight button structure, wherein:

the front surface of the corner is provided with a through hole to expose the key cap of the corner key structure; the side of the corner is provided with an open space for the corner key structure to be installed, and the open space can be closed by a detachable external corner cover so as to facilitate the installation and the disassembly of the corner key structure, wherein: the size of the open space can be adjusted according to the size of the corner key structure. Preferably, the open space is designed to prevent dust from entering and affecting normal use of the key structure. The dust-proof design may take various suitable forms, for example, a sealing material (such as a rubber gasket) may be provided at the junction of the outer rotating cover and the open space; and a corner connector is arranged on the inner side of the corner part to provide a mounting point for the corner key structure. The corner connector is made of a high-strength and wear-resistant material, such as metal (stainless steel, aluminum alloy) or reinforced plastic, so as to ensure that the corner connector can be stable even when the key is frequently used. Structurally, the corner connector may have an L-shaped or V-shaped cross-sectional shape to facilitate installation at the corner. Meanwhile, the corner connecting piece is provided with a reserved mounting hole site, so that the fixing support is convenient to mount. The corner connector is sized according to the size of the display bezel and the size of the corner key structure to ensure that it has sufficient space to accommodate the circuit board and the key cap. Preferably, the corner connector should be installed simply, conveniently and easily for maintenance or replacement, for example, screw fixation, slot insertion, magnetic attraction or fastener fixation may be adopted.

Preferably, the shape of the through hole is matched with the cross-sectional shape of the key cap to ensure smoothness of operation: when the shape of the through hole is matched with that of the key cap, a user can operate the key cap more smoothly when pressing the key cap, and unnecessary friction or clamping stagnation of the key cap in the through hole is avoided. In addition, if the shape of the through hole is completely matched with the shape of the key cap, the lateral movement of the key cap can be reduced to a certain extent, and the stability of the key in the use process is improved. Furthermore, the shape of the through hole is matched with the shape of the key cap, so that the space of the opening part can be reduced, dust and moisture are prevented from entering the inside, and the dustproof and waterproof performances of the product are improved.

Preferably, the corner connector has an L-shaped or V-shaped cross-sectional shape to conform to the shape of the corner.

To sum up, the corner key structure can be arranged in the installation space of the corner of the display frame, and the key cap is exposed to the outside through the through hole arranged on the front surface of the display frame, so that the width of the display screen frame can be reduced as much as possible on the premise that the key is kept on the front surface of the display screen frame.
