Furthermore, the plastic materials of the lock wheel, the left positioning arm, the right positioning arm and the lock cylinder have the characteristics of wear resistance and self lubrication, the strength of the electronic door lock device is ensured, the service life of the electronic door lock device is prolonged, and meanwhile, the device is lighter in weight.
Furthermore, a probe hole, a magnetic reed switch fixing groove and a wire through-inserting hole are respectively processed at the fixed positions of the lock cylinder, and the lock cylinder can only be processed and manufactured by a rapid forming technology.
Furthermore, magnetic steel is arranged in a magnetic steel fixing groove designed on the lock cylinder, probes are fixedly arranged in the probe holes, a magnetic reed switch is arranged in the magnetic reed switch fixing groove, two ends of the magnetic reed switch are respectively connected with the two probes through leads, a probe signal acquisition circuit board 19 is arranged at the connecting position of the lock shell and the lock head, and after the electronic door lock is assembled, 2 probe signal acquisition points on the probe signal acquisition circuit board are respectively connected with a probe A and a probe B in a compression mode, so that acquisition of probe signals is guaranteed.
Furthermore, the electromagnet assembly comprises an electromagnet 7, a metal push rod 6 and a metal push rod connector 11, the metal push rod connector is made of plastic materials and is provided with a groove, and a magnetic element 24 is fixedly installed in the groove. The circuit control board is provided with a precise magnetic field sensor 25 at a corresponding position, and when the circuit control board detects that the magnetic element moves to an ideal position, a level signal is output outwards.
Further, when the precise magnetic field sensor senses the existence of the magnetic element, the circuit control board drives the electromagnet component to insert the metal push rod into the metal push rod fixing groove 22, and the method can realize the controllability of opening and closing the door of the electric appliance and extremely low power consumption when the door of the electric appliance is opened.
When the electric appliance box door is not normally closed, the lock tongue fixedly mounted on the box door is not correctly inserted into the side lock tongue groove 16 or external force is not applied to the side lock tongue groove to push the lock wheel to rotate anticlockwise around the lock wheel shaft, and the magnetic steel is fixed relative to the lock wheel, so that the magnetic steel is far away from the magnetic reed switch (shown in figure 2) at the moment and can not drive the magnetic reed switch to be closed, and the magnetic reed switch is represented as being blocked, namely the probe A and the probe B are blocked.
When the door of the electric appliance box is normally closed, the lock tongue fixedly arranged on the door of the box passes through the side lock tongue guide groove 14 and contacts with the side lock tongue groove on the lock wheel, so that the lock wheel is pushed to move anticlockwise by taking the lock wheel shaft as a center, and the magnetic steel also moves anticlockwise. When the magnetic steel moves above the magnetic reed switch, and the magnetic reed switch senses the existence of the magnetic steel, the magnetic reed switch is closed, so that the probe A and the probe B are conducted (shown in figure 3), the correct insertion of the lock tongue can be judged, and the door of the electric appliance box is closed in place. When the normal insertion of the lock tongue is detected, that is, the closing of the electric appliance box door is judged to be in place, the electromagnet is driven by the circuit control board, and then the boosting metal push rod is inserted into the push rod fixing groove to limit the movement of the lock wheel, so that the locking operation of the electric appliance box door is achieved; if need unblock electrical apparatus chamber door, only need circuit control panel to remove the drive to electromagnet assembly, the reed that electromagnet assembly inside helping hand kick-backed can the helping hand metal push rod leave the push rod fixed slot to this restriction to the locking wheel of removing can realize opening of electrical apparatus chamber door.
All parts and all positions in the lock head are designed very carefully, and corresponding functions are achieved through the cooperation of all the parts. For example, as shown in fig. 3, when the magnetic reed switch correctly detects the position of the magnetic steel, at this time, the push rod fixing groove has also moved above the metal push rod, and the metal push rod connected with the push rod moves upwards under the action of the electromagnet, and is accurately inserted into the push rod fixing groove, so that accurate positioning is realized.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art.
