Detailed Description

In order to make the technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings. It is to be understood that the described embodiment may be preferred, but is intended to cover only some, but not all, embodiments of the invention.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "left", "right", "vertical", "horizontal", "tail", "inner", "outer", "positive", "negative", "start position", "end position", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, which are only for convenience of description and simplification of description, and are not to be construed as limiting the present invention.

Fig. 1 shows the effect of the motor lock.

Fig. 2 to 6 show a specific embodiment of the internal structure of the motor lock. The motor lock comprises a housing comprising an upper shell 11 and a lower shell 12. The motor 21 is vertically fixed in the cavity of the lower shell 12, the driving shaft of the motor 21 is connected with the transmission sleeve 31, and one side of the transmission sleeve 31 is provided with a pulling rod 311. The driving sleeve is adjacent to and connected with the lock tongue sleeve 51, one side surface of the lock tongue sleeve 51 facing the driving sleeve 31 is provided with a connecting hole 512, and the pull rod 311 of the driving sleeve 31 is movably connected with the connecting hole 512 of the lock tongue sleeve 51. When the motor 21 drives the transmission sleeve 31 to rotate, the transmission sleeve 31 drives the lock tongue sleeve 51 to move left and right. The upper surface of the lock bolt sleeve 51 is provided with a movable hole 511, the tail part of the lock bolt 61 is provided with a connecting column 611, the lock bolt 61 is sleeved in the lock bolt sleeve 51, and the lock bolt 61 can be movably arranged in the lock bolt sleeve through the matching of the movable hole 511 and the connecting column 611. The latch tongue 61 is hollow inside, and a spring 41 is placed in the hollow structure, and the spring 41 is transverse to the shell. One end of the spring 41 is positioned in the bolt and is propped by the bolt, and the other end is propped by the shell. The housing is also fixed with a circuit board 71, and a first position switch 711 and a second position switch 712 are arranged in the circuit board. The tail of the bolt 61 is also provided with a projection 612. The protrusion 612 is used to touch the first position switch 711 or the second position switch 712. The circuit board 71 further includes a third position switch 713, the upper case 11 is provided with a through hole 111, the through hole 111 corresponds to the third position switch 713, and a lock catch (not shown) matching with the motor lock is provided with a top pillar, and the top pillar is used for triggering a signal of the third position switch. When the top column of the lock catch touches the third position switch of the circuit board, the position of the door body can be detected, the door body is judged to be in a closed state, and the motor lock is triggered to initiate a locking instruction according to the position.

As shown in fig. 4, when the motor lock is unlocked, the motor 21 drives the transmission sleeve 31 to rotate forward, the pull rod 311 of the transmission sleeve 31 drives the lock tongue sleeve 51 to move to the right, the lock tongue 61 retracts into the housing under the driving of the lock tongue sleeve 51, and the protrusion 612 of the lock tongue can touch the first position switch 711 of the circuit board. Based on the signal transmitted from the first position switch 711, the position of the lock tongue can be known, so that the state of the electromechanical lock can be known.

As shown in fig. 5, when the motor lock is locked, the motor 21 drives the driving sleeve 31 to rotate reversely, the pull rod 311 of the driving sleeve 31 drives the latch sleeve 51 to move to the left, the latch 61 extends out of the housing under the thrust of the spring 41, and the protrusion 612 of the latch can touch the second position switch 712 of the circuit board. Based on the signal from the second position switch 712, the position of the bolt can be known, and thus the state of the electromechanical lock can be known. In the locking process of the motor lock, if the lock tongue cannot be aligned with the lock hole and is pinned, the motor 21 drives the transmission sleeve 31 to rotate reversely, the pull rod 311 of the transmission sleeve 31 drives the lock tongue sleeve 51 to normally move towards the left side, and the spring 41 in the lock tongue 61 is still in a compressed state. In this process, although the latch tongue 61 is caught, the latch tongue sleeve 51 is normally movable, thereby protecting the motor. Since the latch tongue 61 is not pushed out, the protrusion 612 on the latch tongue 61 cannot touch the second position switch 712, and therefore the locking operation of the electric lock may not be completed.

The existing locks for medium and large-sized sales counter are generally arranged on the top end. Because the cabinet body is higher, the only upper end of cabinet door is locked, and the lower extreme of cabinet door can be pulled open the slit, still can steal the action through the slit. An effective solution is that the lock is also installed at the lower end of the sales counter, but the cost of the equipment is increased, and the risk of managing and controlling two locks is higher than the risk of managing and controlling one lock. Therefore, the motor lock can be arranged in the middle of a sales counter, and the lock catch is arranged in the middle of the cabinet door and matched with the motor lock. This reduces the risk of failure, i.e. without increasing the cost of the sales counter.

For an unmanned sales container, particularly an unmanned sales container based on image recognition, automatic settlement is carried out after a door is opened to obtain a commodity required by the self and the door is closed, and the sales container judges the commodity obtained by a user at a server end to form a purchase order based on the image recognition technology. The image recognition-based unmanned sales counter comprises at least two layers of shelves, wherein each layer is provided with a camera which is connected to a processor, and the processor is connected with a background server through a network; the camera shoots real-time image information of goods to be sold on the goods shelf and sends the real-time image information to the background server through the processor; and the background server identifies the commodities and the quantity taken away by the user according to the image information before opening the cabinet and after closing the cabinet to settle accounts. Therefore, such devices need to obtain signals through the device side for the server to make some judgments. In the invention, the first position switch and the second position switch are touch switches, and signals need to be obtained through direct touch. The third position switch may be a touch switch or an inductive switch. The inductive switch can be a reed switch or a Hall element, and the trigger piece can be a magnet or magnetic steel. The inductive switch and the trigger may also be a pair of light sensitive switches. The inductive switch is a non-touch switch, and obtains signals through magnetic induction or light induction.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified and recombined, or some technical features may be equivalently replaced; and the modifications, the recombination or the replacement do not make the essence of the corresponding technical scheme depart from the scope of the technical scheme of the embodiments of the invention.
