Detailed Description

Exemplary embodiments that embody features and advantages of the present invention will be described in detail in the following description. It is to be understood that the invention is capable of other and different embodiments and its several details are capable of modification without departing from the scope of the invention, and that the description and drawings are to be regarded as illustrative in nature and not as restrictive.

Referring to fig. 1 to 4, the present embodiment provides a motor lock device installed on the inner side of a door, which can be used with a single lock head, a card swiping panel, a fingerprint panel or a password panel installed outside the door. The motor lock device comprises a lock shell 1, a lock shell mounting plate 2 matched with the lock shell 1, a pinch plate piece 3 matched with the lock shell 1, a pinch plate mounting plate 4 matched with the pinch plate piece 3, a knob 5, a connecting rod 6, a shifting peach 7, a motor 8, a first gear 9, a second gear 10, a shifting rod 11 and a bolt piece 12.

Wherein, one end of the connecting rod 6 is fixedly connected with the knob 5 positioned at the outer side of the lock shell 1, and the other end is inserted into the lock shell 1. The connecting rod 6 is fixedly connected with the shifting peach 7, and when the connecting rod 6 rotates, the shifting peach 7 also rotates together. The shift peach 7 is in driving connection with the bolt piece 12, and when the shift peach 7 rotates, the bolt piece 12 is driven to extend or retract in the lock shell 1.

The motor 8 is fixed in the lock shell 1 through the pressure plate 801, and the output shaft of the motor 8 is coaxially connected with the first gear 9 and can drive the first gear 9 to rotate. The second gear 10 is rotatably fitted over the connecting rod 6 and is engaged with the first gear 9. In particular, the first gear 9 and the second gear 10 are both helical gears. The shifting peach 7 is provided with an arc hole 701. One end of the shift lever 11 is fixedly connected to the second gear 10 and rotates with the second gear 10, and the other end of the shift lever 11 is inserted into the arc hole 701. When the motor 8 drives the first gear 9 to rotate, the second gear 10 rotates together with the shift lever 11, and the shift lever 11 pushes the shift lever 7 to rotate, thereby driving the latch 12 to extend or retract in the lock case 1.

This scheme both can order about the star 7 through motor 8 and rotate, also can order about star 7 through knob 5 and rotate to when rotating knob 5, because second gear 10 rotationally overlaps on connecting rod 6, consequently connecting rod 6 is together rotated can not be followed to second gear 10, and first gear 9, motor 8's output shaft also can not rotate because of connecting rod 6, thereby has realized protection motor 8, has guaranteed motor 8 life's effect.

Specifically, referring to fig. 5, the lock case 1 has a hollow structure.

Referring to fig. 6, the cross section of the connecting rod 6 is substantially a middle rectangle and two semicircular ends.

Referring to fig. 7, the peach pull 7 includes a peach pull body and a push block 702. Wherein, the peach-shifting main body is provided with a mounting hole which is matched with the shape of the connecting rod 6 and the arc-shaped hole 701. Similarly, the mounting hole is also rectangular in the middle and semicircular at two ends. Thus, when the connecting rod 6 rotates, the shifting peach 7 is also driven to rotate together. The push block 702 extends out of the main body and is inserted into the notch 123 of the latch member 12.

Referring to fig. 8, one end of the latch bolt 12 is a bolt body 121, and the other end is an actuating arm 122 with a notch 123. Notch 123 is funnel-shaped, and both sides are equipped with the inclined plane, and when thumb peach 7 rotated, this inclined plane can be parallel gradually with between the terminal surface of ejector pad 702, guarantees that ejector pad 702 can smoothly promote bolt spare 12.

With reference to fig. 8, the driving arm 122 is provided with an elongated limiting hole 124 along the length direction. Referring to fig. 6, a vertical limiting rod 101 is disposed in the lock case 1, and the limiting rod 101 is inserted into the limiting hole 124 to limit the extension length of the bolt 12 in the lock case 1.

Referring to fig. 10, the middle portion of the second gear 10 is a circular hole having an inner diameter larger than an outer diameter of the connecting rod 6, so that the second gear 10 does not rotate when the connecting rod 6 rotates. One side of the second gear 10 is provided with a vertical shift lever 11.

Referring to fig. 11, the motor lock apparatus further includes an anti-lock switch 13. As shown in fig. 9, a first stopper 125 is disposed at one end of the transmission arm 122 close to the latch body 121. The back lock switch 13 includes a push rod 131, a slider 132, and a second stopper 133. As shown in fig. 5, the lock case 1 is provided with a slide groove 102 for receiving the locking member. A slide 132 is slidably disposed in the chute 102. The push rod 131 is fixedly connected with the slide block 132 and extends out of the lock shell 1. The second stopper 133 is fixedly connected to the other side of the slider 132. Preferably, the counter lock switch 13 of the present embodiment is produced in an integrally molded manner. In order to prevent the lock switch 13 from falling off the sliding slot 102, the lock switch 13 further includes a cover plate 134 (see fig. 2) covering the lock switch 13, and the cover plate 134 is provided with an avoiding hole for the second stopper 133 to pass through.

Referring to fig. 12, when the lock switch 13 moves to the right (in the illustrated direction), the second stopper 133 and the first stopper 125 are in tandem. Thus, when the latch 12 is extended or retracted, the first stopper 125 collides with the second stopper 133 and is stopped by the second stopper 133, so that the latch 12 cannot move. At the moment, the lock can not be unlocked outside the door, and the lock can be unlocked only by pushing the back locking switch 13 inside the door, so that the anti-theft performance is greatly enhanced.

Referring to fig. 1 and 4 together, the motor lock apparatus further includes a battery case 14 for accommodating a battery and a battery case cover 15. Wherein, a containing groove for containing a plurality of batteries (such as No. 7 batteries) is arranged in the battery box 14, and an elastic arc-shaped fixture block 141 for clamping the batteries is arranged in the containing groove. The right end of the lock shell 1 is provided with a step. The battery case 14 is mounted at the step. The battery case cover 15 covers the battery case 14 and is flatly engaged with the outer surface of the lock case 1.

Referring again to fig. 2, the lock case mounting plate 2 of the present embodiment is embedded in the lock case 1, and the pinch plate mounting plate 4 is embedded in the pinch plate member 3, so that the outer surface of the device is relatively flat. A plurality of through holes are formed in the lock shell mounting plate 2 and the buckle plate mounting plate 4, and the device can be mounted on the inner side of a door through the through holes.

More preferably, as shown in fig. 3, in the present embodiment, a transistor placing groove 103 for accommodating a transistor is provided on one side of the lock case 1 close to the buckle member 3. A magnet placing groove 301 for accommodating a magnet is arranged at a position of one side of the buckle piece 3 close to the lock shell 1 corresponding to the triode placing groove 103. Like this, after closing the door, lock shell 1 aligns with buckle spare 3, and triode standing groove 103 also aligns with magnet standing groove 301, and after the triode monitored magnet, electric control module will control the power and give motor 8 power-on, and motor 8 orders about first gear 9, second gear 10, driving lever 11, dial peach 7 rotation again to order about spring bolt main part 121 and stretch out from lock shell 1, inject buckle spare in, realize automatic the locking.
