This utility model discloses a precision embedded fully enclosed linear module, including a base plate. Two side plates are welded to the upper end of the base plate. Steel plates are welded to both sides of the two side plates, and the two steel plates are welded to the base plate. Guide grooves are provided on adjacent sides of the two side plates. A moving block is slidably connected between the two side plates. Protruding portions are provided on both the front and rear sides of the moving block, and these protruding portions are slidably connected to the two guide grooves. A placement platform is fixedly connected to the upper end of the moving block, and a through channel is provided within the placement platform. This utility model's linear module is completely enclosed from the machining workshop, thus preventing dust and other debris from adhering to the surface of the transmission components and reducing accuracy. It also prevents debris generated during the operation of the transmission components from entering the machining workshop and can collect debris generated by transmission wear, ensuring transmission accuracy.

The utility model relates to a waveform rotor, a brushless motor and a harmonic reducer, the waveform rotor is used for integration of the brushless motor and the harmonic reducer, the waveform rotor comprises a rotor main body, the rotor main body is provided with an elliptical outer circumferential surface and a circular inner circumferential surface, and the circular inner circumferential surface can be used for uniformly arranging permanent magnets. And the elliptical outer peripheral surface can be used as a wave generator of the harmonic reducer, so that the rotor of the brushless motor and the wave generator of the harmonic reducer are integrated into a whole. According to the waveform rotor, the rotor of the brushless motor and the wave generator of the harmonic reducer are combined, so that the waveform rotor can be used as the rotor of the brushless motor and the wave generator of the harmonic reducer at the same time, integration of the brushless motor and the harmonic reducer is achieved, the number of speed reduction parts adopting the waveform rotor is reduced, and the appearance is more compact; the size and the weight are correspondingly reduced, and the current application requirements of miniaturization and light weight can be met.

The utility model discloses an intelligent watch and PCB mainboard thereof. The PCB mainboard comprises: a mainboard main body; a plurality of functional circuit areas arranged on the mainboard main body, electronic components and / or metal wiring being arranged in the functional circuit areas; a plurality of signal isolation areas arranged on the mainboard main body, a plurality of first through holes penetrating through the mainboard main body being arranged in the signal isolation areas; and the plurality of first through holes are arranged in sequence at the edges of the signal isolation areas, so as to reduce signal interference and loss between different functional circuit areas.
