[0018] Figure 2 This is a connection block diagram of a preferred embodiment of the logistics smart lock of the present invention. DETAILED DESCRIPTION

[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] Please refer to FIG. 1 and FIG. 2 , which are a preferred embodiment of the present invention. The logistics intelligent lock includes a mechanical lock 100, a limiting structure 130 and a control module 300. The mechanical lock 100 includes a lock chain 110 and a lock body 120. A lock rod 111 is disposed at at least one end of the lock chain 110. The lock rod 111 is movably disposed in the lock body 120. A lock bolt for clamping the lock rod 111 when the lock is closed is disposed in the lock body 120. The limiting structure 130 includes a limiting column 131 and a driving mechanism 134. The driving mechanism 134 is fixedly connected to one end of the limiting column 131. The other end of the limiting column 131 is used to abut against the lock bolt to limit the lock bolt when the lock is closed. The mechanical lock 100 also includes a chain detection mechanism 2 for detecting whether the chain 110 is illegally opened. 00, the chain detection mechanism 200 includes a detection spring piece 210 that contacts the lock rod 111 when locked, a lock core 240, a sensor 220 for detecting whether the lock core 240 is in the locked position or the unlocked position, and an alarm module 230. The lock core 240 is connected to the driving mechanism 134, and the driving mechanism 134 drives the lock core 240 to move between the locked position and the unlocked position. The detection spring piece 210, the sensor 220, and the alarm module 230 are respectively electrically connected to the control module 300. The detection spring piece 210, the chain 110, and the control module 300 form a chain detection circuit. When the lock core 240 is in the locked position and the chain detection circuit is a non-closed circuit, the alarm module 230 gives an alarm. The above components are further described in detail below.

[0021] The logistics smart lock is mainly used to lock the doors, containers, etc. of logistics tools and to locate the logistics tools or containers. It includes a mechanical lock 100, a chain detection mechanism 200, a control module 300, an RFID module 400, a power module (not shown in the figure) and a positioning module 600.

[0022] The mechanical lock 100 includes a chain 110 , a lock body 120 and a limiting structure 130 . The chain 110 and the lock body 120 cooperate with each other to lock the target to be locked, and the limiting structure 130 prevents the chain 110 and the lock body 120 from accidentally separating.

[0023] The lock chain 110 includes a lock rod 111, a lock slot 112 and a guide portion 113. There are two lock rods 111, which are respectively arranged at the two ends of the lock chain 110, and the lock rods 111 are movably arranged in the lock body 120. When the lock needs to be closed, the lock rod 111 is inserted into the lock body 120; when the lock needs to be unlocked, the lock rod 111 is pulled out from the lock body 120. In order to lock, a lock slot 112 is provided on the lock rod 111. In order to facilitate locking and unlocking, guide portions 113 are provided on both sides of the lock slot 112, and the guide portions 113 are surfaces inclined toward the lock slot 112.

[0024] The lock body 120 is in a block shape as a whole, and includes a main body 122, a lock hole 121, a lock bolt and an elastic member (not shown in the figure). The lock hole 121 is a through hole that runs through the main body 122, and its inner diameter is adapted to the outer diameter of the lock rod 111, and the lock rod 111 can move in the lock hole 121. Specifically, the lock rod 111 can enter the main body 122 from one end of the lock hole 121 and extend from the other end of the lock hole 121. The lock bolt and the elastic member are arranged inside the main body 122, and the direction in which they are arranged is perpendicular to the extension direction of the lock hole 121. The lock bolt is fixedly connected to the elastic member, and the elastic member is fixed to the main body 122, that is, the lock bolt is fixed in the main body 122 through the elastic member. The lock bolt extends under the action of the elastic member to enter the lock groove 112 provided on the lock rod 111, clamp the lock rod 111, and prevent the lock rod 111 from detaching from the lock body 120. The elastic member is preferably a spring. The guide portions 113 on both sides of the locking slot 112 facilitate the locking bolt to enter or escape from the locking slot 112 .

[0025] Furthermore, in order to prevent the lock bolt from accidentally detaching from the lock body 120 under the action of external force, the limiting structure 130 limits the lock bolt after the lock bolt clamps the lock rod 111. The limiting structure 130 includes a limiting column 131, a limiting hole 132, a limiting column connecting plate 133, a lock core 240 and a driving mechanism 134.

[0026] The main body 122 is also provided with a limiting hole 132, which is arranged parallel to the lock hole 121, and whose inner diameter is adapted to the outer diameter of the limiting column 131, so that the limiting column 131 can move in the limiting hole 132. When the lock needs to be closed, the lock bolt extends forward and enters the lock slot 112, and one end of the limiting column 131 extends under the drive of the driving mechanism 134, and abuts against the rear end of the lock bolt to prevent the lock bolt from moving backward, so that the lock bolt accidentally disengages from the lock body 120. When the lock needs to be unlocked, the limiting column 131 retracts under the drive of the driving mechanism 134, and when the lock rod 111 is pulled outward, the lock bolt disengages from the lock slot 112, and the locking of the lock rod 111 is released.

[0027] Since there are two locking rods 111, there are two corresponding limit posts 131, and the other ends of the two limit posts 131 are connected together through a limit post connecting plate 133. The driving mechanism 134 is connected to the limit post connecting plate 133, thereby driving the limit posts 131 to extend or retract. The driving mechanism 134 is electrically connected to the control module 300, and the control module 300 controls the working state of the driving mechanism 134.

[0028] The logistics smart lock of the present invention adopts unlocking and locking at both ends of the chain 110 instead of traditional single-sided unlocking and locking. On the one hand, when a fault occurs at one end of the chain 110, the logistics smart lock can still work normally; on the other hand, the load of the driving mechanism 134 is symmetrically set, which reduces the wear and power demand of the driving mechanism 134, extends the life of the logistics smart lock, and reduces the production cost.

[0029] The chain detection mechanism 200 is used to detect whether the chain 110 is illegally opened, and includes a detection spring 210 , a sensor 220 , an alarm module 230 and a lock core 240 .

[0030] The detection spring piece 210 is disposed at one end of the lock hole 121 and is electrically connected to the control module 300. When the lock is closed, the lock rod 111 can contact the detection spring piece 210. In order to correspond to the number of the lock rods 111, in an embodiment of the present application, there can also be two detection spring pieces 210.

[0031] The lock core 240 is connected to the driving mechanism 134, and the driving mechanism 134 drives the lock core 240 to move between the locked position and the unlocked position. In a preferred embodiment of the present application, the driving mechanism 134 is a motor, and the motor includes an output shaft, which is threadedly connected to the lock core 240. When the motor is working, it drives the lock core 240 to move between the locked position and the unlocked position. The lock core 240 is fixedly connected to the above-mentioned limit column connecting plate 133, and when the driving mechanism 134 is working, it drives the lock core 240 and the limit column 131 to move at the same time.

[0032] The sensor 220 is disposed near the lock cylinder 240 and is electrically connected to the control module 300 to detect whether the lock cylinder 240 is in a locked position or an unlocked position and to send a locked position or unlocked position signal to the control module 300. Specifically, the sensor 220 includes but is not limited to a position sensor or an infrared sensor.

[0033] The alarm module 230 is electrically connected to the control module 300 and is used to generate an alarm when the mechanical lock 100 is illegally damaged.

[0034] When the lock is closed, the locking rod 111 is inserted into the lock body 120, the locking bolt clamps the locking rod 111, and the end of the locking rod 111 contacts the detection spring 210. The detection spring 210 and the chain 110 and the control module 300 form a chain detection circuit; at the same time, the driving mechanism 134 drives the limit column 131 and the lock core 240 to move, the limit column 131 contacts the locking bolt, and the lock core 240 moves to the locked position. The sensor 220 detects the locking signal and sends the locking signal to the control module 300. When the lock core 240 is in the locked position and the chain detection circuit is a non-closed circuit, the alarm module 230 alarms.

[0035] The RFID module 400 is electrically connected to the control module 300 to detect whether the RFID used for unlocking is legal. If it is legal, the unlocking signal is sent to the control module 300. The control module 300 controls the limit structure 130 to release the limit on the lock bolt. At the same time, the lock cylinder 240 moves to the unlocking position. The sensor 220 sends the unlocking position signal to the control module 300. At this time, the lock rod 111 is pulled outward to unlock the door without triggering the alarm module 230. RFID, also known as wireless identification, is a communication technology that can identify specific targets and read and write related data through radio signals without establishing mechanical or optical contact between the identification system and the specific target. The present invention adopts a keyless design, is green and safe, and has high reliability.

[0036] The control module 300 includes a mainboard 310 and a single-chip microcomputer 320, the mainboard 310 is electrically connected to the single-chip microcomputer 320, and the RFID module 400 is electrically connected to the mainboard 310 and the single-chip microcomputer 320, respectively. In order to save power and extend the standby time of the logistics smart lock, in most cases, the mainboard 310 is in a dormant state, and the single-chip microcomputer 320 monitors and wakes up the mainboard 310 when necessary, such as unlocking. With such a setting, the standby time of the logistics smart lock can be greatly extended to 30 days. Of course, in order to simplify the structure, in other embodiments, the control module 300 may also include only the mainboard 310, but not the single-chip microcomputer 320.

[0037] The positioning module 600 is used to track the location of the logistics smart lock, including at least one of a satellite positioning unit, a GPS positioning unit or a mobile network positioning unit. The logistics smart lock can use a variety of positioning units to work alone or in cooperation with each other, with a wide selection range and high positioning accuracy, and can be positioned in specific situations where the weather and environment are not good.

[0038] When the positioning module 600 includes a mobile network positioning unit, an unlocking signal can be sent to the mobile network positioning unit through the user's terminal device, and the mobile network positioning unit sends the unlocking signal to the control module 300, thereby performing remote legal unlocking without RFID. A positioning module cover 610 can also be provided on the outside of the positioning module 600 to prevent the positioning module 600 from being damaged.

[0039] The power module is electrically connected to the driving mechanism 134, the control module 300, the sensor 220, the alarm module 230, the control module 300, the RFID module 400 and the positioning module 600 respectively to supply power to the above devices.

[0040] The logistics smart lock also includes a shell 700, a waterproof rubber pad 710, etc., which are waterproof and impact-proof, and play a role in protecting the internal structure of the logistics smart lock.

[0041] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scopes based on the ideas of the present invention. As long as these changes do not deviate from the concept of the present invention, they all belong to the protection scope of the present invention.
