One end of the first main swing arm is hinged to the base, and the other end of the first swing arm is hinged to the first connector. When the rotating mechanism rotates between an unfolded state and a folded state, a rotation angle of the first main swing arm relative to the base is smaller than a rotation angle of the first door panel relative to the base.

Abstract: An electronic device which includes a rear cover, a mounting member, a camera assembly, and a decorative ring. The rear cover is provided with a mounting hole. The mounting member is fixed to an inner wall of the rear cover, a part of the mounting member protrudes from the mounting hole, and the part of the mounting member that protrudes from the mounting hole is provided with a fixing hole. The camera assembly includes a lens, where the lens is fixed to the fixing hole. The decorative ring is fixed to the part of the mounting member that protrudes from the mounting hole, where the decorative ring abuts against an inner wall of the mounting hole, a surface of the decorative ring away from the mounting member is a first surface, the first surface is an inclined surface.

Abstract: An electronic device and an electronic device assembly method. A through hole is provided in a rear cover. An inner wall of the through hole protrudes to form an annular flange. A camera decorative member is designed to include an inner decorative member and an outer decorative member. The outer decorative member is arranged on a side of the rear cover facing away from a middle frame and is connected to the annular flange by a bonding layer, and the inner decorative member is fastened to a side of the outer decorative member facing the middle frame, so that a gap between the outer decorative member and the annular flange can be blocked by the bonding layer, and the bonding layer is used for sealing to prevent water in an external environment from entering the electronic device through space between the outer decorative member and the rear cover.

Abstract: An electronic device comprises a housing and a camera decoration assembly including a first decoration part and a second decoration. The second decoration part sleeves an outer side surface at an end, outside the housing, of the first decoration part, and an outer edge of the second decoration part extends to an outer surface of the housing, such that in addition to a camera decoration assembly having diverse appearance effects, a size of a hole formed in the housing can be decreased to enhance overall strength of the housing. Moreover, a form of connection between a buckle and a connection assembly facilitates disassembly, decreases occupied space, and can increase flexibility in disassembling the camera decoration assembly.

Abstract: Embodiments of this application provide a rear cover of an electronic device, an electronic device, and an air tightness detection system of an electronic device. The electronic device may include a mobile or fixed terminal having waterproof performance such as a mobile phone, a tablet computer, or a notebook computer. The rear cover includes a body portion and a structure layer fixed to a rear surface of the body portion. A smooth detection plane is formed on a rear surface of the structure layer, and a rear end of a balance channel of the rear cover is located within the detection plane, thereby resolving the problem that the material of the rear cover affects air tightness detection on the electronic device.

Abstract: This application provides a folding assembly and a foldable electronic device. The folding assembly is applied to a foldable electronic device, and is configured to carry a flexible display screen. The folding assembly includes a shaft base, a first housing, and a second housing. The first housing and the second housing are respectively disposed on both sides of the shaft base. A door plate swing arm is located above the shaft base and is disposed on each of both sides of a center line of the shaft base, one end of each door plate swing arm is rotatably connected to the shaft base, and the other end of each door plate swing arm is rotatably connected to the first housing or the second housing.

Abstract: A fingerprint module includes a fingerprint component, a button component, a support, and a resilient fixing element. The button component is fastened to a lower surface of the fingerprint component. The resilient fixing element is disposed on the lower surface of the fingerprint component and is located between the fingerprint component and the support. The resilient fixing element surrounds the button component, and the resilient fixing element resiliently connects the fingerprint component and the support. There is a gap between the button component and the support. When the fingerprint component is pressed, the resilient fixing element deforms, the gap becomes smaller, and the button component comes in contact with the support.

Abstract: A battery cover is applied to the electronic device and configured to couple to a housing of the electronic device, and includes a glass substrate. A non-transparent layer is disposed on a first side of the glass substrate. At least one first through-hole is disposed on the non-transparent layer opposite to a camera assembly disposed in the electronic device. A camera region is disposed on the first side of the glass substrate disposed opposite to the at least one first through-hole. A film-coated layer is disposed in the camera region of the glass substrate. An area of the camera region is greater than or equal to an area of the at least one first through-hole.
