Abstract: A fixing structure used to connect a display panel to a housing of an electronic device during manufacture of the electronic device includes a fixing member, an auxiliary member spaced apart from the fixing member, and supporting posts disposed between the fixing member and the auxiliary member. The fixing member is to be bonded to the display panel. A projection of an outer edge of the auxiliary member on a plane of the fixing member is outside of an outer edge of the fixing member. The supporting posts and the auxiliary member are removed after the display panel is bonded to the fixing member. A method for assembling the display panel with the fixing structure is also disclosed.

Abstract: A hinge assembly includes two hinge arms, a fixing structure, and a plurality of balls. Each of the two hinge arms includes a gear portion. A shaft hole and at least one groove are defined on the gear portion, and the shaft hole connects to the at least one groove. The fixing structure includes two central shafts, each of the two central shafts passes through the shaft hole respectively. Each ball is accommodated in the at least one groove. The balls are in interference fit with the two central shafts. The balls and the two central shafts generate a damping force while they rotate relative to each other or tend to rotate relative to each other to maintain the position of the two hinge arms. The hinge assembly has a long service life and sufficient space. A terminal device is provided according to the present disclosure.

Abstract: An air purification equipment and an air purification method are provided, including a housing, a purification device, a guiding assembly, and an air driving device. The housing defines an air inlet and an air outlet, the air inlet imports air into the housing, the air outlet exports air out of the housing. The purification device purifies the air in the housing. The guiding assembly guides the air from the air inlet to the purification device. The air driving device drives the air from the air inlet to the purification device, and drives the air to the air outlet. The guiding assembly forms a first channel and a second channel, the first channel is corresponding to the air inlet, the first channel guides the air to flow into the second channel, at least a part of the purification device is positioned in the second channel.

Abstract: A fixing device for accurately fixing an optical assembly to a rear housing of an electronic device fixes the optical assembly in a predetermined position and includes a cover plate. The cover plate defines a hole and a limiting portion. The hole corresponds to a photosensitive portion of the optical assembly and the photosensitive portion is configured to protrude out of the cover plate. The limiting portion is configured to limit a movement of the optical assembly away from the rear housing before being fixed in position. The fixing device fixes the optical assembly in the predetermined position so that the assembly accuracy and efficiency are improved. An optical module including the fixing device, and an electronic device including the optical module are also provided.
