A buckle assembly and an electronic device using the buckle assembly are provided. The buckle assembly is assembled in a housing of the electronic device. The housing has an inner surface and a column with a first through hole, wherein the column protrudes from the inner surface toward inside of the housing. The buckle assembly includes a fixing element, a shaft and a pair of retaining rings. The fixing element is assembled in the first through hole. The shaft is fixed in the housing. The retaining rings are pivoted to the shaft. Each of the retaining rings has an arc portion, and the retaining rings buckle each other and abut on the column. The arc portions are co-constructed to form a first hole communicating with the first through hole while the retaining rings buckle each other, and the fixing element is inserted in the first hole and column to be fixed in the housing.

The invention relates to a power MOSFET with a Miller clamp function, belonging to the technical field of power semiconductor devices. A power MOSFET (insulated gate field effect transistor) with a Miller clamp function of the present invention can discharge the charging and discharging current on the Miller capacitor to the source through a monolithically integrated BJT (bipolar transistor) and Only a small amount of gate-source voltage drop is generated, which effectively reduces the risk of false turn-on of the power MOSFET caused by charging and discharging the Miller capacitor, and greatly improves the short-circuit robustness of the device.

The invention provides a multifunctional mainboard module support, an electric appliance box with the same, and an air conditioner. The multifunctional mainboard module support is used for the electric appliance box. At least one clamping buckle and at least one spigot are arranged on the front surface of the multifunctional main board module support; at least one heating element accommodating groove is formed in the back surface of the multifunctional mainboard module support; each heating element accommodating groove is provided with a flange; through holes corresponding to an electric appliance box mainboard are formed in each clamping buckle and each spigot respectively; the multifunctional mainboard module support is connected with the electric appliance box mainboard in a buckled mode; and after screws penetrate through the through holes of the multifunctional mainboard module support, the electric appliance box mainboard can be connected with a radiator. The heat dissipation ofheating elements can be facilitated, and meanwhile, production is facilitated; the utilization rate of the mainboard can be increased, and board arrangement and wiring are facilitated; insects and other animals can be prevented from climbing to the back surface of the electric appliance box mainboard from the front surface of the mainboard, so that insect prevention is achieved; and the short-circuiting fault and burnout of the electric appliance box mainboard which are caused by the condition that insects climb to pins on the back surface of the mainboard can be avoided.

The invention relates to a motor with a braking energy recovery function for a new energy vehicle. The motor comprises a main body, an output shaft, a first gear, a recycling mechanism and a dust removing box. The main body is internally provided with a PLC, a rotor and a stator. The dust removing box is internally provided with a dust removing mechanism. The recycling mechanism comprises a storage battery, a casing, a rotating shaft, a return pipe, a compressor, a connecting rod, a second gear and a plurality of blades. A control unit is arranged in the second gear. The dust removing mechanism comprises a dust cleaning unit, a drying pipe, a drying chamber and an air intake unit, and the air intake unit includes a third gear, a rotating rod, a roller, a thread, an air intake pipe and a communication pipe. According to the motor with a braking energy recovery function for a new energy vehicle, through the recycling mechanism, the kinetic energy of the rotor of the motor is recovered and stored in the storage battery in braking or coasting, and the unit energy consumption of the motor is reduced. Moreover, the dust removing mechanism can prevent water, mud or foreign matter from entering the inside of the motor from a vent hole, and the motor is prevented from being short-circuited and burned.

The invention discloses a new type of incubator, which comprises: an incubator, multiple pairs of egg tray resting blocks, a plurality of egg trays and a lifting device. By placing the egg trays eccentrically on the egg tray resting blocks, the eggs are lifted by the lifting device. The tray realizes the flipping of the egg tray, and then relies on the self-gravity of the egg tray to automatically reverse the reverse rotation. At the same time, the lifting device is used to control the speed of the egg tray reverse flipping, so as to realize the stable and reliable flipping of the egg tray. In addition, through the folding plate and the lifting device in the lifting device The heat insulation board keeps the temperature and humidity in the hatching room as stable as possible. The present invention realizes the function of turning eggs inside the small incubator by arranging multiple pairs of egg tray shelving blocks and lifting devices in the incubator.
