Abstract: A wearable device includes a main body, a housing, and two connection elements fixed to the housing. The connection element includes a body and at least one elastic protrusion protruding from one side of the body. When mounting the main body to the housing, the elastic protrusion of the connection element is deformed to generate elastic force to fix the main body to the housing.

Abstract: An exemplary charger is to charge an electronic device, which includes one first contact. The charger includes a housing, a lithium battery, a circuit board. The housing includes a top cover and a bottom cover attached to the top cover. The top cover defines at least one through hole. The lithium battery is fixed in the housing. The lithium battery is electrically connected to the circuit board. The circuit board includes a second contact. The second contact passes through the through hole and is external to the top cover. When the at least one first contact contacts the at least one second contact, an electrical connection is created between the electronic device and the charger, the charger charges the electronic device through the lithium battery.

Abstract: An electronic device includes a front cover and a back cover. A number of first connecting members are fixed to the back cover, and each of the plurality of first connecting members is made of elastically deformable material and defines a first hole. A number of second connecting members are fixed to the front cover, and each of the plurality of second connecting members includes a protruding post. The protruding post engages the first hole to connect the front cover to the back cover.

Abstract: A wrist worn device is provided. The wrist worn device includes a cover, a case, and a rotatable ring. The case is coupled to the cover. The case includes a switch. The rotatable ring is rotatably arranged between the cover and the case. A number of protrusions protrude from the surface of the rotatable ring. Each protrusion can move together with the rotatable ring to a position to actuate the switch.

Abstract: A monitor includes a base member, a rotatable portion, a monitor body, and a screw. The base member has a mounting end. The rotatable portion is assembled on the mounting end and defines a latching slot and a screw hole communicating with the latching hole. The monitor body has a latching protrusion engaged with the latching slot of the rotatable portion. The screw corresponds to the screw hole for locking the latching protrusion in the latching slot of the rotatable portion.

Abstract: A display device includes a glass sheet, a front frame, and a fastening device. The glass sheet is used for protecting a display module disposed in an enclosure of the display device. The front frame is a part of the enclosure of the display device. The fastening device has a first surface and a second surface opposite to the first surface. The first surface is glued to the glass sheet with adhesive. The second surface is detachedly attached to the front frame.
