Abstract: The present application relates to a speed reduction rotation device based on photovoltaic modules, which includes a high tooth-slot torque permanent magnet motor and a planetary reducer. The output of the motor is connected to the input of the planetary reducer. The motor includes a stator body with multiple stator slots and a rotor body with permanent magnets, where the ratio of stator slots to magnets is a multiple of 3:2. This application utilizes the high tooth-slot torque of the permanent magnet motor, which, when amplified by the speed ratio of the planetary reducer, achieves sufficient reverse braking torque to resist reverse torque on the actuator shaft caused by external forces. Additionally, replacing the worm gear reducer with the planetary reducer for speed reduction and rotation of the actuator shaft improves service life, energy efficiency, and reliability while reducing product costs.

Abstract: The present disclosure discloses a head-wearable displaying and powering system, comprising a head-wearable display device, a portable terminal and a powering device; the powering device comprises a first communication interface for connecting to the portable terminal and a second communication interface for connecting to the head-wearable display device; a data pathway is disposed between two communication interfaces to implement direct communication between the head-wearable display device and the portable terminal; when the powering device is simultaneously connected with the portable terminal and head-wearable display device, the powering device powers the head-wearable display device, and the head-wearable display device does not consume electrical power of a battery of the portable terminal. Meanwhile, the head-wearable display device is directly connected to the portable terminal. When the powering device is only connected with the portable terminal, the powering device powers the portable terminal.

Abstract: The head-wearable display device according to the present invention is provided with one communication interface via which the head-wearable display device is connected with a portable terminal, to obtain audio and video data from the portable terminal, exchange data with the portable terminal and obtain working power supply from the portable terminal. As compared with current externally-connected type head-wearable display device which has to employ a plurality of cables, the head-wearable display device according to the present invention may operate normally in a way of connecting with the portable terminal via only one cable, without occupying too many communication interfaces of the portable terminal, avoids the problem that the head-wearable display device and portable terminal cannot establish connection because types and number of communication interfaces on the portable terminal cannot meet the needs of the head-wearable device.

Abstract: The present disclosure discloses a head-wearable displaying and powering system, comprising a head-wearable display device and a portable terminal; the head-wearable display device is provided with one communication interface to connect with the portable terminal; The portable terminal, through the communication interface, transmits audio and video data to the head-wearable display device, exchanges data with the head-wearable display device and provides the working power supply to the head-wearable display device. The head-wearable display device may operate normally after being connected to the portable terminal only via one communication interface, needn't occupy too many communication interfaces on the portable terminal and does not limit the application of the portable terminal. As the head-wearable display device acquires the working power supply mainly from the portable terminal, the problem of the overheating of the product caused by the heat generation of the built-in battery is avoided.
