An electronic device is provided. The electronic device includes a first body with a base and a movable member, a second body, a lifting member, and a linkage mechanism. The movable member is located on an upper surface of the base and includes a first side and a second side. The first side is pivotally connected to the base. The second body is pivotally connected to the second side by using a first rotary shaft. The lifting member is pivotally connected to the movable member by using a second rotary shaft. The linkage mechanism is disposed on the movable member, is linked to the second body by using the first rotary shaft, and drives the lifting member to rotate by using the second rotary shaft. When the second body is opened upward, an air outlet on a rear side of the first body is prevented from being covered.

A protective cover (10) for a portable computing device (1) provides a fuel source (14) disposed within a compartment in the protective cover. The fuel source may be a hydrogen fuel source suitable for delivering hydrogen to a fuel cell (15) within the protective cover or within the portable computing device, for generating electrical power for use by the portable computing device. The protective cover may have a plurality of planar panels (11) separated by a one or more hinge regions (12) which can each house a fuel source compartment. The protective cover may also be serviceable as a stand.

A portable computing device such as a laptop computer has a base unit (2) and a display screen unit (3) coupled together by a hinge assembly (7) configured to allow rotation of the base unit and the screen unit relative to one another. The display screen unit has a display panel on a first face of the display screen unit and a fuel cell array (12a, 12b) disposed adjacent to a second face of the display screen unit. Ventilation apertures through the second face of the display screen unit provide air flow to the fuel cell array. A fuel conduit extends between the base unit and the display screen unit across the hinge assembly for delivering fuel from the base unit to the display screen unit.

A foldable display device is provided. The foldable display device includes a flexible display module, a bottom frame, middle frames, and a connecting member. Two ends of the connecting member are provided with filter components. An accommodating cavity is formed among the flexible display module, the middle frames and the bottom frame communicating with an external environment through the filter components, so as to prevent the dust generated by the friction of components of the connecting member and the dust entering the accommodating cavity from the external environment, thereby avoiding short circuits and display malfunction of the foldable display device.

The laptop includes a host, a screen and a heat dissipation structure. The screen is pivotally connected to the host and includes a clamp member. The heat dissipation structure is connected to the host adjacent to where the screen is pivotally connected and covers a back of the host. The heat dissipation structure includes a back case body and a hatch cover. The back case body defines a heat dissipation opening. One side of the hatch cover is pivotally connected to the back case body. The hatch cover is set to match the heat dissipation opening. When the screen is closed with respect to the host, the clamp member urges the hatch cover to close the heat dissipation opening; when the screen is open with respect to the host, the clamp member is released from the hatch cover, and the hatch cover rotates to expose the heat dissipation opening.

An electronic device including two bodies, at least one hinge assembly, and a hinge cover is provided. The two bodies are pivoted to each other through the hinge assembly. The hinge cover is connected between the two bodies and covers the hinge assembly. The hinge cover includes a plurality of shell parts, and the shell parts are movably connected to each other in sequence. The hinge cover has at least one first heat dissipation opening and at least one heat dissipation flow channel, and the at least one heat dissipation flow channel communicates the first heat dissipation opening and an inner space of at least one of the bodies.

Volumetric resistance blowers are disclosed herein. An example volumetric resistance blower includes a housing, a motor, and a rotor disposed within the housing and rotated by the motor. The rotor is constructed of metal foam.

A portable electronic device is disclosed. The portable electronic device may include a laptop computing device that includes a base portion and a display housing rotationally coupled to the base portion. The base portion includes a fan designed to drive heated air out of the base portion, thus cooling the portable electronic device. A dynamic (movable) air diverter is integrated into the base portion near the fan's outlet. The air diverter is designed to direct airflow from the fan outlet. Moreover, the air diverter can be repositioned by, for example, rotating the display housing relative to the base portion. As a result of the repositioned air diverter, the airflow from the fan outlet is redirected out of the portable electronic device through a different location. The air diverter can be positioned in different discrete locations, or alternatively, can move continuously with the rotational movement of the display housing.
