Abstract: A housing module having a circuit board quick-assembling function is applied to an electronic device with a circuit board having a specific height. The housing module includes a housing, an spacer and two pivoting components. The housing includes a substrate and several lateral boards. The spacer includes a main body, two pivoting portions and a locking portion. The pivoting portions are disposed on corresponding sides of the main body, the locking portion stretches from a lower side of the main body and is fixed on the circuit board via an external fixing component. The pivoting portions pass through the lateral boards and are connected to the pivoting portions. While the circuit board slides relative to the substrate to push the spacer, the main body is rotated inside the housing via the pivoting portions to lift the lower side.

Abstract: A server includes a case and function modules. The case includes a frame, a first upright partition and a second upright partition. The frame has an internal space and an opening. The opening corresponds to the internal space. The first upright partition and the second upright partition jointly define a first accommodating portion, a second accommodating portion and a third accommodating portion in the internal space. Each of the function modules is a first function module, a second function module or a third function module. A width of the first function module is half of the width of the second accommodating portion. The width of the first function module, a width of the second function module and a width of the third function module have a ratio of 1:2:4.

Abstract: A light guiding structure includes a resilient base and a plurality of light guiding columns. A plurality of through holes is separately formed on the resilient base. The plurality of light guiding columns resiliently engages with the plurality of through holes. Each of a plurality of light emitting components is disposed on an end of each of the plurality of the light guiding columns. The light guiding structure utilizes the plurality of light guiding columns for guiding the light transmitted from the plurality of light emitting components and further utilizes the resilient base for allowing the light transmitted from one of the plurality of light emitting components to pass through the corresponding light guiding column only. Therefore, the light transmitted from the plurality of light emitting components can be guided to a correct position, which effectively reduces human misjudgment.

Abstract: A server device including a chassis having an accommodating space and an opening, a least one server having a front part and a back part, and at least one connecting rod assembly having a first connecting rod, a second connecting rod, and a third connecting rod. The server may be located in the accommodating space and be drawable from the opening. The first connecting rod is pivoted on the front part of the server. The second connecting rod is pivoted on the back part of the at least one server.

Abstract: A foldable supporting mechanism includes at least one hinge secured to a device, a bracket rotatably fixed to the device by the at least one hinge, and an elastic assembly secured to the at least one hinge. The supporting mechanism provides an elastic force to retain the bracket at an angle with the device when the bracket is unfolded. When the bracket is folded, the elastic assembly restores to continue urging the bracket to be fully retracted against the device. The at least one buffering assembly impedes the free rotation of the bracket relative to the device when the bracket is being unfolded and when it is being folded. An electronic device having the supporting mechanism is also provided.
