Abstract: A non-contact force type micro-rotating mechanism driven by attractive/repulsive force and a manufacturing method thereof, belongs to the field of intelligent micro devices, and mainly relates to micro electromechanical system technology, precision machining technology, precision assembly and the like. The mechanism adopts the interaction force between magnetic poles to replace the connection mode of a traditional through-hole bearing pressure spring positioning shaft, so that the component part structure of the mechanism can be optimized, and the space utilization rate can be greatly improved. Moreover, the attractive force type structure also has the effect of weakening the radial vibration of the motor, and the coaxiality of the rotor and the stator is improved in the running process of the motor. Meanwhile, the rotating mechanism does not directly output shaft work, a structure can be added on the disc-shaped rotor to realize different functions, an actuator and a control object are integrated.

Abstract: A folding vehicle roof top tent. The fixed base is in a ladder shape and fixed to the vehicle roof, and one end of the fixed base is connected to one end of the movable base which is in a ladder shape by a pair of the connection block assemblies. Each of the connection block assembly comprises a first connection block connected to the fixed base, a second connection block connected to the movable base, and a main connection block, both the first connection block and the second connection block are hinged to the main connection block. The support is hinged to the main connection block. The tent cloth covers the support in a fixed manner, and bottom edges of the tent cloth are fixedly connected to the fixed base and the movable base simultaneously. One end of the telescopic ladder is hinged to the other end of the movable base.
