Abstract: An electronic device having an expansion interface includes a shell, a button, a circuit board, switch and a voltage adjusting unit. The shell defines a through hole. The button is movably received in the through hole. The button includes a first electroluminescent portion and a second electroluminescent portion. The switch is electrically connected to the circuit board and is activated by the button to control whether to load a same voltage to the first electroluminescent portion and a second electroluminescent portion to drive them to emit light of equal brightness. The voltage adjusting unit changes the voltage loaded to the second electroluminescent portion to drive the second electroluminescent portion to emit light having a different brightness from the light emitted from the first electroluminescent portion when an expansion device is connected to the expansion interface.

Abstract: A mounting apparatus for securing a display includes a base; a clipping device attached to the base, a first positioning device attached to the base, and a second positioning device attached to the base. The clipping device includes a first securing member and a second securing member. The clipping device is moveable relative to the base between a locked position and an unlock position. When the clipping device is located on the locked position, the first securing member and the second securing member are configured to secure to a display. When the clipping device is located on the unlock position, the first securing member is engaged with the first positioning device, the second securing member is engaged with the second positioning device, thereby the first securing member and the second securing member are configured to remove from the display.

Abstract: An electronic device enclosure includes a chassis, a mounting tray attached to the chassis, a handle rotatably attached to the mounting tray, and a resilient member. The handle includes a securing post. The resilient member includes a first portion, a second portion, and a curling portion connected to the first portion and the second portion. The curling portion is engaged with the securing post. The first portion is engaged with the handle, and the second portion extends out of the handle and abuts the mounting tray. The handle is rotated away from the mounting tray to deform the resilient member, and the resilient member is released to rotate the handle towards the mounting tray.

Abstract: An automatic vending machine includes a front door, a thermal insulation door, and a latching member. The thermal insulation door is rotatably secured to the front door. The latching member is secured to the thermal insulation door and engages with the front door to prevent the thermal insulation door from rotating relative to the front door, so that the thermal insulation door is secured to the front door without screws.

Abstract: A vending machine includes a mounting bracket and a balance assembly. The mounting bracket includes two side panels and a cover panel pivotably mounted between the two side panels. The balance assembly includes a loading arm, a loading panel secured to the loading arm, and a balance member secured to the loading arm. The loading arm is pivotably mounted between the two side panels. The loading panel and the balance member are mounted to opposite sides of the loading arm to maintain the loading panel in a first position. The loading panel includes a panel body and an engaging member. The engaging member blocks the cover panel from rotating inward. The loading panel rotates from the first position to a second position after a product is dropped on the loading panel, and the engaging member is moved down to unblock the cover panel.

Abstract: An electronic device enclosure includes a front bezel defining a first slot and a second slot; and a light assembly secured to the front bezel and including a lamp duct, a light guiding board, and one or more LED lamps. The lamp duct and the light guiding board are secured to the front bezel. The lamp is secured to the lamp duct. The light guiding board includes a light guiding rib aligned with the first slot. The lamp emits light or different lights according to the volume and different types of media played by the electronic device light.

Abstract: An enclosure includes a chassis, a side panel and a knob structure. The chassis includes a rear panel in which a latching hole is defined. The knob structure includes a mounting member, a sliding member engaged in the mounting member, a positioning member secured to the side panel and a resilient member elastically engaged between the sliding member and the positioning portion. The mounting member is secured to the side panel. The sliding member includes a hook. The sliding member can slide from a first position to a second position; when the sliding member is in the first position, the hook engages in the latching hole, when the sliding member is in the second position, the hook disengages from the latching hole; the resilient member elastically deforms to bias the sliding member to slide from the first position to the second position.

Abstract: A mounting apparatus includes a drive bracket, a maintaining plate and a mounting bracket, the drive bracket includes a bottom plate, a first side plate and a second side plate, a receiving space is defined among the bottom plate, the first side plate and the second side plate, the receiving space is divided into a top portion and bottom portion by the maintaining plate. The top portion is adapted to secure a first disk drive, the mounting bracket is secured to the bottom portion of the two portions and configured for securing a second disk drive that is smaller than the first disk drive.
