Description

Technical Field

[0001] The present invention relates to the technical field of door locks, and particularly to a low-power intelligent motor and an intelligent door lock. Background Art

[0002] As is well known, an electric starter is what people usually refer to as a motor today, also known as a starter. It drives the rotation of the starter rotor by the force of a current-carrying coil in a magnetic field. The small gear on the rotor drives the engine flywheel to rotate, thereby driving the crankshaft to rotate and start the vehicle. The innovation of two components, a new low-cost spark plug with a porcelain core base and a starter, laid the technical foundation for the development of automobiles.

[0003] The electric starter discarded the heavy and dangerous hand crank, making driving a car safer, easier, and more convenient, and was especially favored by a large number of new consumer groups including women. At that time, Henry Leland, the manager of the Cadillac division of General Motors, immediately keenly perceived the potential of this technological achievement and quickly adopted it as a standard configuration for the 1912 version of the Cadillac model of the company. This Cadillac was thus named the "crankless car". The advent of the electric starter is still recognized as the most influential automotive innovation of the 20th century.

[0004] For example, the patent with the publication number "CN201495854U" and the patent name "Intelligent Motor Electronic Lock" discloses that "the present invention discloses an intelligent motor electronic lock, including a lock body and a lock tongue. The lock tongue (20) of the lock is a device structure driven by an electric motor. An electric motor (40) and a microcontroller device (30) are provided inside the lock body (10). The electric motor is connected to a transmission slider (50) through a transmission eccentric wheel (41) connected to the motor shaft. A key input structure (61) is provided on the outer panel (60) of the lock. The electric motor (40) drives and controls the execution action of the lock tongue (20) through the input signal of the key (61). It increases the anti-impact strength of the lock tongue, solves the problem that the lock tongue of an electronic lock using an electromagnet will retract when being impacted, uses an electronic key, eliminates the need to carry a physical key, has a large number of keys, can also store unlocking records and execute alarm actions, and is small in size and more convenient to install than ordinary electronic locks."

[0005] It is found in the use of existing intelligent motor electronic locks that they are inconvenient to assemble without a motor. After the lock body is impacted, the motor is not firmly fixed and is prone to dislocation, resulting in the lock body being unable to continue to be used. There is no heat dissipation device and dust removal device, the working environment of the motor cannot be adaptively adjusted, and the service life of the motor is low, resulting in relatively high limitations in its use.
