Abstract: A display apparatus includes a display panel, a mirror switching screen, a first photosensitive sensor, a first flexible circuit board and a driver board. The mirror switching screen is disposed on a light-exit side of the display panel. The first photosensitive sensor is configured to sense a light intensity of ambient light at a side of the mirror switching screen away from the display panel. The first flexible circuit board includes a bonding portion, a component portion and a wiring portion. The bonding portion is electrically connected to the mirror switching screen. The first photosensitive sensor is disposed on a side of the component portion proximate to the mirror switching portion. The wiring portion has lines electrically connected to the first photosensitive sensor and bonding pads of the bonding portion. The driver board is electrically connected to the wiring portion of the first flexible circuit board.

Abstract: The present disclosure provides a rear-view device, including a helmet and a rear-view image guiding system arranged on the helmet. The rear-view image guiding system includes a light conduction optical fiber bundle, and an objective lens group and an eyepiece lens group arranged at two ends of the light conduction optical fiber bundle respectively; the helmet includes a first cladding region and a second cladding region; the objective lens group is arranged in the second cladding region, and configured to convert received incident light into parallel light; the light conduction optical fiber bundle is configured to transmit the parallel light to the eyepiece lens group; and the eyepiece lens group is configured to converge the parallel light and transmit convergent light to an eye region of the helmet.

Abstract: A rearview mirror includes a display device, at least one switch, a photosensitive sensor, a rear housing and a button. The at least one switch, the photosensitive sensor and the rear housing are disposed on a non-display side of the display device. The photosensitive sensor is configured to sense a light intensity of ambient light located on the non-display side of the display device. An avoidance opening is disposed in the rear housing, and exposes the photosensitive sensor and the at least one switch. The button is disposed on a side of the photosensitive sensor and the at least one switch away from the display device, and is connected to the rear housing at the avoidance opening. The button has a light-transmitting region. The button is configured to receive a pressing operation to trigger a respective switch in the at least one switch.

Abstract: The present disclosure provides a rotation type electric toothbrush. The electric toothbrush includes a brush handle module, a vibration module and a brush head module having a brush base, a brush cover and bristles. The brush cover and the brush base are in a detachable connection. The bristles are disposed on the brush base. The brush base includes a groove. The vibration module includes a motor and an eccentric shaft having a transmission connection with the motor. The eccentric shaft inserts into the groove. When the rotation type electric toothbrush is working, the eccentric shaft rotates eccentrically to contact a side surface of the groove, so as to drive the brush base and the brush cover to have a reciprocating rotation synchronously.

Abstract: The present disclosure provides an electric toothbrush including a driving module, a connection shaft, a battery supporter, a support cover, a print circuit board and a switch. The driving module includes a driving element, a driving element supporter, a reset elastic element and a stress element. The connection shaft passes through the driving element supporter and the battery supporter. The driving element is used to drive the driving module to rotate from a starting position to a triggering position and make the reset elastic element generate elastic deformation. In the starting position, the driving element supporter is separated from the switch, and the switch is in an OFF state. In the triggering position, the driving element supporter contacts the switch and the switch is in an ON state, and the driving module rotates to the starting position with a reset force of the elastic deformation of the elastic element.
