Summary of the Invention

In order to overcome the above-mentioned defects, the first purpose of the present invention is to provide a small-sized universal electronic lock as defined by claim 1, comprising a driving mechanism. By reasonably setting positions of a power supply assembly, a motor assembly, and a driving member, the electronic lock is small in size, convenient to transport and mount, and lower in cost.
In order to achieve the above-mentioned purposes, technical solutions of the present invention are defined by the dependent claims.
By reasonably setting positions of the motor, the gear assembly and the driving member, the driving mechanism is smaller in occupied spatial size; and based on the reduction of the size, the corresponding material loss and the cost are lower. Therefore, an electronic lock adopting the driving mechanism is small in size, convenient to transport and mount, and lower in cost. Moreover, the electronic lock is wider in application scope in addition to smaller size so as to become a universal electronic lock.
Due to the arrangement of the motor groove and the driving member groove, the motor and the driving member are mounted more conveniently and stably.
In the electronic lock, by reasonably setting positions of the power supply assembly, the motor and the driving member in the sequential arrangement of the power supply assembly, the motor and the driving member, the electronic lock is small in size and convenient to transport and mount; and based on the reduction of the size, the corresponding material loss and the cost are lower. Moreover, based on the arrangement that the motor is directly disposed on a side of the power supply assembly, when the motor is electrically connected with the power supply assembly, the phenomenon that a conducting wire between the motor and the power supply assembly is overlong due to an overlong distance therebetween can be avoided, and the position of the conducting wire can be more conveniently set, so that the electronic lock is more convenient to mount and lower in cost. Moreover, the electronic lock is smaller in size and wider in application range so as to become a universal electronic lock.
Battery grooves and PCB grooves respectively located on upper and lower sides of the battery housing ensure that the internal space of the battery housing can be more reasonably utilized, so that the overall structure of the power supply assembly is smaller.
By disposing the structures of the battery grooves and the PCB groove, the internal space of the battery housing can be more reasonably utilized, so that the overall structure of the power supply assembly is smaller.
Due to the arrangement that the keys are exposed out of the battery housing after penetrating through the isolating bulge, the internal space of the battery housing can be more reasonably utilized, so that the overall structure of the power supply assembly is smaller.
The battery surface cover is capable of playing a role in fixing the batteries, thereby playing a role in protecting the batteries.
Due to the arrangement that the battery surface cover is detachably connected with the upper side of the battery housing by the buckling structure, the batteries can be replaced by removing the battery surface cover when being damaged.
The driving through hole may penetrate through the lower side of the mounting housing, so that the driving connecting part is exposed out of the mounting housing after penetrating through the driving through hole; and a silica gel pad is fixedly disposed on the lower side of the mounting housing, and the driving through hole penetrates through the silica gel pad, so that the driving connecting part is exposed out of the silica gel pad after penetrating through the driving through hole. By using the silica gel pad, a door can be prevented from being scratched when the electronic lock is mounted on the door.
The present invention has the beneficial effects that in the electronic lock, by reasonably setting positions of the power supply assembly, the motor assembly and the driving member in the sequential arrangement of the power supply assembly, the motor assembly and the driving member, the electronic lock is small in size and convenient to transport and mount, and lower in cost. Moreover, based on the arrangement that the motor assembly is directly disposed on a side of the power supply assembly, when the motor assembly is electrically connected with the power supply assembly, the phenomenon that a conducting wire between the motor assembly and the power supply assembly is overlong due to an overlong distance therebetween can be avoided, and the position of the conducting wire can be more conveniently set, so that the electronic lock is more convenient to mount.
