Abstract: An electronic device includes a housing and a button. The housing has a first surface and a second surface opposite to the first surface, and defines a mounting hole passing through the first surface and the second surface. The mounting hole has an inner surface. The button is received in the mounting hole, and includes a metallic keycap and an annular buffer member. The keycap has a peripheral side surface, and defines a receiving groove on the peripheral side surface which extends around the peripheral side surface. The buffer member is composed of flexible material, sleeved on the keycap cap, partially received in the mounting hole, and partially positioned outside of the mounting hole to resist the second surface of the housing.

Abstract: A support and cushioning device for supporting and holding an electronic device includes a first supporting assembly, a fixed bracket, an adjusting board, and a plurality of elastic members. The adjusting board is mounted to the distal end of the first support assembly. The fixed bracket is elastically mounted to the adjusting board by means of a plurality of elastic members. The fixed bracket includes a base body and a plurality of holding arms extending out from a periphery of the base body. The plurality of holding arms and the base body cooperatively define a holding space for holding an electronic device.

Abstract: An electronic device housing includes a bottom housing, a support plate, a display panel, and a side frame. The support frame is welded in the bottom housing. The display panel is positioned on the support plate. The side frame is connected to a top edge of the bottom housing, such that the display panel is sandwiched between the support plate and the side frame. A manufacturing method for an electronic device housing is also provided.

Abstract: An electronic device housing includes a bottom housing, a support frame, a display panel, and a side frame. The bottom housing includes a base plate and four sidewalls extending from a periphery of the base plate. The support frame is welded to the sidewalls of the bottom housing. The support frame is received in the bottom housing and made up of at least two support plates, two ends of each are welded to ends of the adjacent support plates. The support frame forms at least two welding lines at joints of the at least two support plates, and each welding line corresponds to a middle portion of one sidewall. The display panel is positioned on the support frame sandwiched between the support frame and the side frame. The side frame is connected to a top edge of the bottom housing.

Abstract: A machining device includes a support platform, a machining assembly, a clamping assembly, a driving assembly, and a controlling assembly. The support platform includes a first supporting member, a sliding rail mounted on the first supporting member, and a second supporting member mounted on the sliding rail. The machining assembly mounted on the second supporting member includes a machining tool. The clamping assembly is mounted on the first supporting member, for clamping and rotating the workpiece. The driving assembly is fixed to the second supporting member. The controlling assembly includes a connecting member mounted on the second supporting member and a resisting member mounted on the connecting member. The driving member drives the second supporting member to slide along the sliding rail, to make a gradual and increasing depth of contact by the machining tool on the workpiece, until a preset limit is reached.
