Problems solved by technology
The electromagnet needs enough working current to release the constraints on the transmission parts during use, and the stepper motor needs not only enough working current, but also needs a hardware program drive. There are driving devices such as electromagnets and stepper motors A common feature is that a relatively large operating current is required, which obviously cannot be satisfied in the passive mode; the operating voltage required by the DC geared motor is relatively low, generally between 1.5V and 4.5V, and the operating current is between 1.5V and 4.5V. 20mA to 100mA can work normally, but how to control the DC geared motor to achieve stable torque output and finally achieve intelligent release of constraints for the transmission mechanism is still an unsolved structural problem

The invention discloses an unlocking device and an intelligent lock for an intelligent lock, wherein the unlocking device includes a housing, a pull plate bracket, an unlocking shaft mechanism, an unlocking kit mechanism and a DC geared motor mechanism; the DC geared motor used in the present invention Drive the transmission gear and the unlocking gear to rotate, and then provide the power required for the unlocking operation of the smart lock, so that in the ultra-low power consumption mode, for example, the working voltage is only 1.5V to 4.5V, and the working current is only 20mA to 100mA. The transmission mechanism inside the smart lock can obtain the torque required to release the restraint stably, without being affected by any external transmission mechanism, and can realize ultra-low power consumption driving. The invention can be widely used in the technical field of intelligent locks.
Description
technical field [0001] The present invention relates to the field of intelligent locks, in particular to an unlocking device of an intelligent lock and an intelligent lock. Background technique [0002] In passive mode, the operating current provided to the smart lock is usually mA (milliampere) level, which is only suitable for low-power, low-power driving devices, and the driving devices are limited by the weak The working current cannot output strong torque during operation, which makes it extremely difficult for the intelligent lock to realize intelligent operation in passive mode. [0003] At present, the interior of most smart locks uses the structural mode of lateral restraint. In addition to the necessary transmission components, various elastic parts that are necessary for the reset of each component are also required. To remove the internal restraint, the elastic parts must be overcome. Only the resistance can realize the internal lifting action, so as to realize ...
