[0002] A vending machine is a device that sells goods through automation technology and is widely used in various places, such as stations, shopping malls, office buildings, etc. The vending machine locks and unlocks the door through a door lock device.

[0003] In the related art, the door lock device of the vending machine includes an electromagnetic lock body and a lock plate with a magnet. The electromagnetic lock body is installed on the top of the machine box, and the lock plate with a magnet is installed on the top of the door body. When the door body is opened, the lock plate and the magnet on the lock plate rotate with the door body. When the door body is closed, the electromagnetic lock body and the lock plate lock and cooperate to lock the door body.

[0004] However, the door lock device of the relevant vending machine only locks the top of the door body and the box body. Due to the high height of the door body, the bottom of the door body is easily affected by external force to form a gap between the box body and the box body, resulting in the theft of goods in the box, reducing the anti-theft performance of the vending machine.

When the first locking rod and the second locking rod move away from each other until the first locking rod and the first locking structure are locked and matched, the second locking rod and the second locking structure are also locked and matched, so that the top and bottom of the door body are locked and matched with the box body, so that the bottom of the door body is difficult to separate from the box body under the action of external force, thereby improving the anti-theft performance of the vending machine. When the first locking rod and the second locking rod move toward each other until the first locking rod and the first locking structure are unlocked, the second locking rod and the second locking structure are also unlocked, so that the top and bottom of the door body are unlocked from the box body, and at this time the door body can rotate relative to the box body under the action of external force to open the storage chamber.

[0018] In some embodiments of the present application, the linkage mechanism includes:

[0019] The first transmission member includes:

[0020] A first connecting portion, hinged to the first locking rod;

[0021] A second connection portion is spaced apart from the first connection portion and is rotatably arranged relative to the door body;

[0030] The linkage structure is respectively connected to the first transmission shaft and the second transmission shaft so that the first transmission shaft and the second transmission shaft rotate in opposite directions.

[0031] With such arrangement, the linkage structure causes the first transmission shaft and the second transmission shaft to rotate in opposite directions, thereby driving the first locking rod and the second locking rod to move toward or away from each other.

[0032] In some embodiments of the present application, the linkage structure includes:

[0033] A first gear is arranged on the first transmission shaft, and the first transmission shaft rotates with the first gear;

[0034] The second gear is arranged on the second transmission shaft. The second transmission shaft rotates with the second gear. The second gear is meshed with the first gear.

[0035] With such arrangement, the second gear rotates in opposite directions to the first gear, driving the first transmission member and the second transmission member to rotate in opposite directions, thereby causing the first locking rod and the second locking rod to move toward or away from each other.

[0036] In some embodiments of the present application, the first connecting portion is configured with a first movable hole;

[0037] The linkage mechanism also includes a third transmission shaft, which is movably arranged in the first movable hole, and the third transmission shaft and the first locking rod are pivotally connected.

[0038] In this way, the first connecting part and the first locking rod can be pivotally connected via the third transmission shaft, so that both the first transmission member and the first locking rod can rotate relative to the third transmission shaft, thereby achieving hinged connection between the first connecting part and the first locking rod.

[0039] In some embodiments of the present application, the first movable hole is a long strip hole;

[0040] The lock body component also includes a first guide member, which is arranged on the door body and has a first guide structure. The first locking rod is movably arranged on the first guide structure, and the first guide structure is configured to enable the first locking rod to move along a set direction.

[0041] With such arrangement, the first guide structure can enable the first locking rod to move along a set direction, so as to reduce the deviation of the first locking rod from the set direction during upward or downward movement, thereby improving the stability of the cooperation between the first locking rod and the first locking structure.

[0042] In some embodiments of the present application, the third connecting portion is configured with a second movable hole;

[0043] The linkage mechanism also includes a fourth transmission shaft, which is movably arranged in the second movable hole, and the fourth transmission shaft is pivotally connected to the second locking rod.

[0044] In this way, the third connection part and the second locking rod can be pivotally connected via the fourth transmission shaft, so that the second transmission member and the second locking rod can both rotate relative to the fourth transmission shaft, thereby achieving hinged connection between the third connection part and the second locking rod.

[0045] In some embodiments of the present application, the second movable hole is a long strip hole;

[0046] The lock body component also includes a second guide member, which is arranged on the door body. The second guide member is constructed with a second guide structure. The second locking rod is movably arranged on the second guide structure. The second guide structure is constructed to enable the second locking rod to move along a set direction.

[0047] With such arrangement, the second guide structure can enable the second locking rod to move along a set direction, so as to reduce the deviation of the second locking rod from the set direction during upward or downward movement, thereby improving the stability of the cooperation between the second locking rod and the first locking structure.

[0048] In some embodiments of the present application, the driving mechanism includes an electric driving mechanism, which is configured to convert electrical energy into mechanical energy and drive one of the first locking rod and the second locking rod to move along a set direction.

[0049] With such an arrangement, the electric drive mechanism can realize automatic control of locking and unlocking between the door body and the box body, thereby reducing labor costs.

[0050] In some embodiments of the present application, the lock body component further includes a mechanical drive mechanism, and the mechanical drive mechanism includes:

[0051] A lock cylinder is rotatably arranged relative to the door body;

[0052] A lock hole is constructed on the lock core;

[0053] A sliding member is disposed on the lock core and rotates with the lock core, and the sliding member is eccentrically disposed relative to the rotation center of the lock core;

[0054] a connecting assembly hinged to one of the first locking rod and the second locking rod;

[0055] A third movable hole is configured in the connecting assembly, and the sliding member is slidably disposed in the third movable hole;

[0056] The key can be inserted into the key hole, and the lock core can rotate with the key when the key is inserted into the key hole.

[0057] With such arrangement, when the lock core rotates, the sliding member can drive the connecting assembly to move upward or downward, thereby driving one of the first locking rod and the second locking rod that is transmission-connected to the mechanical drive mechanism to move upward or downward, thereby locking or unlocking the door body and the box body. When the vending machine is powered off or the electric drive mechanism fails, the first locking rod and the first locking structure, as well as the second locking rod and the second locking structure, can be normally unlocked or locked through the mechanical drive mechanism.

[0058] In some embodiments of the present application, the electric drive mechanism is connected to the connecting component and drives the connecting component to move along a set direction.

[0059] With such arrangement, the electric drive mechanism reuses the connection components of the mechanical drive mechanism, thus simplifying the structure of the door lock device.

[0060] In some embodiments of the present application, the connection assembly includes an iron core;

[0061] The electric drive mechanism includes:

[0062] The electromagnet is constructed with a movable channel, the movable channel extends along the axis direction of the iron core, a part of the iron core is inserted in the movable channel, and when the electromagnet is energized, the iron core moves toward the electromagnet along a set direction under the action of the magnetic attraction of the electromagnet;

[0063] The elastic member is respectively arranged on the iron core and the electromagnet. The elastic member is constructed so that when the electromagnet is powered off, the iron core moves away from the electromagnet in a set direction by its own elastic force.

[0064] With such arrangement, when the electromagnet is energized, the iron core moves toward the electromagnet along the set direction under the action of the magnetic attraction of the electromagnet; when the electromagnet is de-energized, the magnetic attraction of the electromagnet on the iron core disappears, and the iron core moves away from the electromagnet along the set direction under the action of the elastic restoring force of the elastic part. In this way, by controlling the electromagnet to be energized or de-energized, one of the first locking rod and the second locking rod can be driven to move upward or downward along the set direction, which is convenient for control.

[0065] In some embodiments of the present application, one of the first locking rod and the second locking rod connected to the electric drive mechanism is spaced apart from the iron core;

[0066] The connecting assembly also includes a first connecting member, an iron core is arranged on the first connecting member, and one of the first locking rod and the second locking rod connected to the electric drive mechanism is hinged to the first connecting member.

[0067] In this arrangement, the first connecting member connects the one of the first locking rod and the second locking rod connected to the electric drive mechanism to the iron core, which simplifies the assembly difficulty between the one of the first locking rod and the second locking rod connected to the electric drive mechanism and the iron core.

The third transmission shaft 634 may be inserted into the first movable hole 6312. The third transmission shaft 634 may also be rotatably disposed on the first locking rod 610. The first connecting portion 6311 and the first locking rod 610 may be pivotally connected via the third transmission shaft 634, so that both the first transmission member 631 and the first locking rod 610 may be rotated relative to the third transmission shaft 634, thereby enabling the first connecting portion 6311 and the first locking rod 610 to be hinged.

[0148] In some embodiments, reference Figure 6 , the first movable hole 6312 may be a long strip hole.

[0154] One, two or more first guide members 640 may be provided. A plurality of first guide members 640 may improve the guiding effect on the first locking bar 610 .

[0155] In some embodiments, reference Figure 6 The linkage mechanism 630 may include a second transmission member 632. The second transmission member 632 may be a connecting rod, a connecting column, a connecting plate, etc. In the drawings, the second transmission member 632 is shown as a long strip connecting plate. The long strip connecting plate has a small thickness, which can reduce the occupied space of the lock body component 60.

[0156] The second transmission member 632 may include a third connection portion 6321, and the third connection portion 6321 may be located at one end of the second transmission member 632. The third connection portion 6321 is hinged to the second locking rod 620.

[0157] In some embodiments, reference Figure 6 , the third connecting portion 6321 may be configured with a second movable hole 6322. The linkage mechanism 630 may include a fourth transmission shaft 635. The axis of the fourth transmission shaft 635 may be parallel to the axis of the third transmission shaft 634. The fourth transmission shaft 635 may be inserted into the second movable hole 6322. The fourth transmission shaft 635 may also be rotatably disposed on the second locking rod 620. The third connecting portion 6321 and the second locking rod 620 may be pivotally connected via the fourth transmission shaft 635, so that both the second transmission member 632 and the second locking rod 620 may rotate relative to the fourth transmission shaft 635, thereby enabling the third connecting portion 6321 and the second locking rod 620 to be hinged.

[0158] In some embodiments, the second movable hole 6322 is a long strip hole. The extension direction of the second movable hole 6322 can be parallel to the direction from the fourth transmission shaft 635 to the second transmission shaft 6332. The extension direction of the second movable hole 6322 can also be inclined at a small angle relative to the direction from the fourth transmission shaft 635 to the second transmission shaft 6332. During the rotation of the second transmission member 632 around the second transmission shaft 6332, the fourth transmission shaft 635 can slide along the second movable hole 6322.

[0159] refer to Figure 3 , Figure 4 and Figure 5 The lock body component 60 also includes a second guide member 650, which can be a guide block, a guide ring, a guide sleeve or other components with a guiding function. The guide member is shown as a guide block in the accompanying drawings.

[0160] The second guide member 650 is disposed on the door body 20 , and the second guide member 650 is configured with a second guide structure 651 .

[0161] In the implementation manner in which the second guide member 650 is a guide block, the second guide structure 651 may be a guide hole, a guide channel or other structures with a guide function.

[0162] In an implementation in which the second guide member 650 is a guide ring, the second guide structure 651 may be a guide channel surrounded by the guide ring.

[0163] The second locking rod 620 is movably disposed on the second guide structure 651, and the second guide structure 651 can enable the second locking rod 620 to move along a set direction to reduce the deviation of the second locking rod 620 from the set direction during the upward or downward movement, thereby improving the stability of the cooperation between the second locking rod 620 and the first locking structure 40.

[0164] One, two or more second guide members 650 may be provided. A plurality of second guide members 650 may improve the guiding effect on the second locking bar 620 .

[0165] In some embodiments, reference Figure 6 The first transmission member 631 may further include a second connection portion 6313. The second connection portion 6313 is spaced apart from the first connection portion 6311. The second connection portion 6313 may be located at an end of the first transmission member 631 away from the first connection portion 6311.

[0166] The second connection part 6313 is rotatably arranged relative to the door body 20. Exemplarily, the linkage mechanism 630 may include a first transmission shaft 6331. The axis of the first transmission shaft 6331 may be parallel to the axis of the third transmission shaft 634. The first transmission shaft 6331 is rotatably arranged relative to the door body 20 with its own axis as the center.

[0167] In some embodiments, reference Figure 7 and Figure 8 The door lock device 30 may further include a lock housing 70. The lock housing 70 may be detachably disposed on the door body 20. A fixing seat 710 may be disposed in the lock housing 70. The first transmission shaft 6331 may be rotatably disposed on the fixing seat 710, so that the first transmission shaft 6331 may be rotatably disposed relative to the door body 20 with its own axis as the center.

[0168] In other embodiments, the first transmission shaft 6331 can be rotatably disposed on the door body 20, so that the first transmission shaft 6331 can be rotatably disposed relative to the door body 20 with its own axis as the center.

[0169] The first transmission shaft 6331 can also be arranged on the second connection part 6313, and drive the first transmission member 631 to rotate around the axis of the first transmission shaft 6331. Since the first connection part 6311 and the second connection part 6313 are arranged at intervals, when the first transmission member 631 rotates around the axis of the first transmission shaft 6331, the first connection part 6311 drives the third transmission shaft 634 and the first locking rod 610 to move upward or downward.

[0170] refer to Figure 6 The second transmission member 632 may further include a fourth connection portion 6323. The fourth connection portion 6323 is spaced apart from the third connection portion 6321. The fourth connection portion 6323 may be located at an end of the second transmission member 632 away from the third connection portion 6321.

[0171] The fourth connection part 6323 is rotatably arranged relative to the door body 20. Exemplarily, the linkage mechanism 630 may include a second transmission shaft 6332. The axis of the second transmission shaft 6332 may be parallel to the axis of the fourth transmission shaft 635. The second transmission shaft 6332 is rotatably arranged relative to the door body 20 with its own axis as the center.

[0172] In the implementation mode in which the door lock device 30 includes a lock housing 70, and a fixing seat 710 is arranged in the lock housing 70, refer to Figure 7 and Figure 8 The second transmission shaft 6332 can be rotatably disposed on the fixed seat 710, so that the second transmission shaft 6332 can be rotatably disposed relative to the door body 20 with its own axis as the center.

[0173] In other embodiments, the second transmission shaft 6332 can be rotatably disposed on the door body 20, so that the second transmission shaft 6332 can be rotatably disposed relative to the door body 20 with its own axis as the center.

[0174] The second transmission shaft 6332 may also be disposed on the fourth connection portion 6323, and drive the second transmission member 632 to rotate around the axis of the second transmission shaft 6332. Since the third connection portion 6321 and the fourth connection portion 6323 are disposed at intervals, when the second transmission member 632 rotates around the axis of the second transmission shaft 6332, the third connection portion 6321 drives the fourth transmission shaft 635 and the second locking rod 620 to move upward or downward.

[0175] refer to Figure 6The linkage mechanism 630 may further include a linkage assembly 633. The linkage assembly 633 is respectively connected to the second connection portion 6313 and the fourth connection portion 6323. The linkage assembly 633 is configured to drive the second connection portion 6313 and the fourth connection portion 6323 to rotate in opposite directions, so that the first locking rod 610 and the second locking rod 620 move toward or away from each other.

[0176] When the first locking rod 610 and the second locking rod 620 move toward each other, when the first locking rod 610 is unlocked from the first locking structure 40, the second locking rod 620 is also unlocked from the second locking structure 50, so that the top and bottom of the door body 20 are unlocked from the box body 10 at the same time. At this time, the door body 20 can rotate relative to the box body 10 under the action of external force to open the storage chamber 110.

[0177] When the first locking rod 610 and the second locking rod 620 move away from each other, when the first locking rod 610 is locked with the first locking structure 40, the second locking rod 620 is also locked with the second locking structure 50, so that the top and bottom of the door body 20 are locked with the box body 10 at the same time. In this way, the bottom of the door body 20 is difficult to separate from the box body 10 under the action of external force, thereby improving the anti-theft property of the vending machine.

[0178] In some embodiments, reference Figure 6 The linkage assembly 633 may include the first transmission shaft 6331 and the second transmission shaft 6332 mentioned above.

[0179] The first connection portion 6311 and the third connection portion 6321 may be located on the same side of a line connecting the axis of the first transmission shaft 6331 and the axis of the second transmission shaft 6332 .

[0180] The linkage assembly 633 may further include a linkage structure 6333. The linkage structure 6333 is respectively connected to the first transmission shaft 6331 and the second transmission shaft 6332 in a transmission manner so that the first transmission shaft 6331 and the second transmission shaft 6332 rotate in opposite directions.

[0181] In some embodiments, reference Figure 6 The linkage structure 6333 may include a first gear 6334. The first transmission shaft 6331 may be passed through the first gear 6334, and the first transmission shaft 6331 may rotate with the first gear 6334.

[0182] The linkage structure 6333 may further include a second gear 6335. The second transmission shaft 6332 may be inserted into the second gear 6335, and the second transmission shaft 6332 may rotate along with the second gear 6335. The second gear 6335 is meshed with the first gear 6334, so that the second gear 6335 and the first gear 6334 rotate in opposite directions, driving the first transmission member 631 and the second transmission member 632 to rotate in opposite directions, thereby causing the first locking rod 610 and the second locking rod 620 to move toward or away from each other.

[0183] In some other embodiments, the linkage structure 6333 may include a first gear 6334. The first transmission shaft 6331 may be passed through the first gear 6334, and the first transmission shaft 6331 may rotate along with the first gear 6334.

[0184] The linkage structure 6333 may further include a second gear 6335 . The second transmission shaft 6332 may be passed through the second gear 6335 , and the second transmission shaft 6332 may rotate along with the second gear 6335 .

[0185] The linkage structure 6333 may further include a rack, which is slidably arranged relative to the door body 20. The first gear 6334 and the second gear 6335 are both meshed with the rack.

[0186] Since the first gear 6334 and the second gear 6335 are both engaged with the rack, the first gear 6334 and the second gear 6335 rotate in opposite directions, driving the first transmission member 631 and the second transmission member 632 to rotate in opposite directions, thereby causing the first locking rod 610 and the second locking rod 620 to move toward or away from each other.

[0187] In some embodiments, the door lock device 30 further includes a driving mechanism that is in driving connection with one of the first locking rod 610 and the second locking rod 620 to drive one of the first locking rod 610 and the second locking rod 620 to move along a set direction.

[0188] Taking the driving mechanism driving the second locking rod 620 to move along the set direction as an example, refer to Figure 6 When the driving mechanism drives the second locking rod 620 to move upward in the set direction, the second transmission shaft 6332 and the second gear 6335 rotate clockwise synchronously, driving the first transmission shaft 6331 and the first gear 6334 to rotate counterclockwise synchronously, and the first connecting part 6311 rotates downward, driving the first locking rod 610 to move downward, thereby causing the second locking rod 620 and the first locking rod 610 to move toward each other.

[0189] When the driving mechanism drives the second locking rod 620 to move downward in a set direction, the second transmission shaft 6332 and the second gear 6335 rotate counterclockwise synchronously, driving the first transmission shaft 6331 and the first gear 6334 to rotate clockwise synchronously, and the first connecting part 6311 rotates upward, driving the first locking rod 610 to move upward, so that the second locking rod 620 and the first locking rod 610 move oppositely, so that the top and bottom of the door body 20 are locked with the box body 10 at the same time, so that the bottom of the door body 20 is difficult to separate from the box body 10 under the action of external force, thereby improving the anti-theft property of the vending machine.

[0190] Of course, the driving mechanism can also drive the first locking rod 610 to move along a set direction, and drive the second locking rod 620 and the first locking rod 610 to move toward or away from each other through the linkage mechanism 630 .

[0191] The driving mechanism only needs to drive one of the first locking rod 610 and the second locking rod 620 to drive the other of the first locking rod 610 and the second locking rod 620 to move in the opposite direction through the linkage mechanism 630, thereby reducing the energy consumption of the lock body component 60.

[0192] In some embodiments, reference Figure 6 , Figure 7 , Figure 8 and Fig. 9 The driving mechanism may include an electric driving mechanism 660, which is configured to convert electrical energy into mechanical energy and drive one of the first locking rod 610 and the second locking rod 620 to move in a set direction, and drive the other of the first locking rod 610 and the second locking rod 620 to move in the opposite direction through the linkage mechanism 630, so that the first locking rod 610 and the second locking rod 620 move toward or away from each other, thereby realizing unlocking and locking of the top of the door body 20 and the box body 10, and unlocking and locking of the bottom of the door body 20 and the box body 10. The electric driving mechanism 660 can realize automatic control of locking and unlocking between the door body 20 and the box body 10, thereby reducing labor costs.

[0193] In some embodiments, the electric drive mechanism 660 may include a connection assembly 672. The connection assembly 672 may include an iron core 6721. The iron core 6721 has ferromagnetism. The iron core 6721 may be in a rod shape. The axis of the iron core 6721 may extend along a set direction. The iron core 6721 may be disposed on one of the first locking rod 610 and the second locking rod 620.

[0194] The electric drive mechanism 660 may further include an electromagnet 661. When the electromagnet 661 is powered on, the electromagnet 661 generates a magnetic field with magnetism, and thus can attract ferromagnetic objects. When the electromagnet 661 is powered off, the magnetic field disappears and it has no magnetism.

[0195] The electromagnet 661 may be configured with a movable channel 662. The movable channel 662 may extend along the axis of the iron core 6721. Part of the iron core 6721 is inserted into the movable channel 662. When the electromagnet 661 is energized, the iron core 6721 moves toward the electromagnet 661 along a set direction under the action of the magnetic attraction of the electromagnet 661. Figure 6 and Fig. 9 When the electromagnet 661 is energized, the iron core 6721 moves upward along the set direction, and drives the second locking rod 620 to move upward along the set direction, so that the door body 20 and the box body 10 are unlocked.

[0196] The electric drive mechanism 660 may further include an elastic member 663. The elastic member 663 may be a spring, a spring sheet or other elastic member, and the elastic member 663 is shown as a spring in the accompanying drawings. One end of the elastic member 663 may be provided on the iron core 6721, and the other end may be provided on the electromagnet 661. Exemplarily, a stopper 664 may be provided on the side wall of the iron core 6721, and the stopper 664 and the electromagnet 661 are spaced apart. The elastic member 663 may be provided between the electromagnet 661 and the stopper 664, and the elastic member 663 is compressed when the electromagnet 661 is energized.

[0197] When the electromagnet 661 is powered off, the magnetic attraction of the electromagnet 661 to the iron core 6721 disappears, and the iron core 6721 moves away from the electromagnet 661 in a set direction under the elastic restoring force of the elastic member 663. Figure 6 and Fig. 9 When the electromagnet 661 is powered off, the iron core 6721 moves downward along the set direction, and drives the second locking rod 620 to move downward along the set direction, so that the door body 20 and the box body 10 are locked and matched.

[0198] In this way, the second locking rod 620 can be driven to move upward or downward along a set direction by controlling the electromagnet 661 to be energized or deenergized, which is convenient for control.

[0199] In some embodiments, reference Figure 6 , the connecting component 672 may also include a first connecting member 6722.

[0200] In other embodiments, the electric drive mechanism 660 may be an electric push rod. The electric push rod may include a telescopic rod, and the axis of the telescopic rod may extend along a set direction. The electric push rod may also include a push rod body, the telescopic rod is disposed on the push rod body, and the push rod body drives the telescopic rod to extend and retract along the set direction.

[0201] The end of the telescopic rod may be disposed at one of the first locking rod 610 and the second locking rod 620 to drive one of the first locking rod 610 and the second locking rod 620 to move upward or downward along a set direction.

[0202] In some embodiments, one of the first locking rod 610 and the second locking rod 620 connected to the electric drive mechanism 660 and the iron core 6721 may be spaced apart.

[0203] The connecting assembly 672 may further include a first connecting member 6722. The first connecting member 6722 may be in the shape of a rod, a plate, etc. Figure 6 The first connecting member 6722 may include a first connecting arm, a second connecting arm and an intermediate connecting arm. The first connecting arm and the second connecting arm are arranged opposite to each other, and the intermediate connecting arm is arranged between the first connecting arm and the second connecting arm.

[0204] The fourth transmission shaft 635 may be passed through the first connecting arm and the second connecting arm to improve the supporting strength of the first connecting member 6722 on the fourth transmission shaft 635 .

[0205] The iron core 6721 can be arranged in the middle connecting arm.

[0206] On the one hand, the first connecting member 6722 can improve the supporting strength of the fourth transmission shaft 635. On the other hand, the one of the first locking rod 610 and the second locking rod 620 connected to the electric drive mechanism 660 can be connected to the iron core 6721, which simplifies the assembly difficulty between the one of the first locking rod 610 and the second locking rod 620 connected to the electric drive mechanism 660 and the iron core 6721.

[0207] In some embodiments, reference Figure 6 , the driving mechanism may further include a mechanical driving mechanism 670 .

[0208] refer to Figure 6 , Fig.10 and Fig.11 The mechanical driving mechanism 670 may include a lock core 671, and the lock core 671 is rotatably arranged relative to the door body 20. In an implementation in which the door lock device 30 includes a lock housing 70, the lock core 671 may be rotatably arranged on the lock housing 70.

[0209] The lock core 671 may be configured with a lock hole 6711. The lock hole 6711 may be oriented toward the front side of the vending machine.

[0210] The lock core 671 may also be provided with a sliding member 6712, and the sliding member 6712 may rotate with the lock core 671. The sliding member 6712 is eccentrically arranged relative to the rotation center of the lock core 671, so that when the lock core 671 rotates, the sliding member 6712 will not rotate in place.

[0211] The mechanical drive mechanism 670 may further include a connection assembly 672 , which may be hinged to one of the first locking rod 610 and the second locking rod 620 .

[0212] The connecting component 672 can be constructed with a third movable hole 6723, and the sliding member 6712 can be slidably disposed in the third movable hole 6723, so that when the lock core 671 rotates, the sliding member 6712 can drive the connecting component 672 to move upward or downward, thereby driving one of the first locking rod 610 and the second locking rod 620 that is transmission-connected to the mechanical drive mechanism 670 to move upward or downward, thereby locking or unlocking the door body 20 and the box body 10.

[0213] When the vending machine is powered off or the electric drive mechanism 660 fails, the first locking rod 610 and the first locking structure 40 , and the second locking rod 620 and the second locking structure 50 can be normally unlocked or locked through the mechanical drive mechanism 670 .

[0214] In some embodiments, the electric drive mechanism 660 and the mechanical drive mechanism 670 may be respectively connected to the first locking rod 610 and the second locking rod 620. For example, the electric drive mechanism 660 may be connected to the second locking rod 620, and the mechanical drive mechanism 670 may be connected to the first locking rod 610. Alternatively, the electric drive mechanism 660 may be connected to the first locking rod 610, and the mechanical drive mechanism 670 may be connected to the second locking rod 620.

[0215] In other embodiments, the electric drive mechanism 660 and the mechanical drive mechanism 670 may be transmission-connected to the same one of the first locking rod 610 and the second locking rod 620. For example, the electric drive mechanism 660 and the mechanical drive mechanism 670 may be transmission-connected to the first locking rod 610 at the same time. Alternatively, the electric drive mechanism 660 and the mechanical drive mechanism 670 may be transmission-connected to the second locking rod 620 at the same time.

[0216] Reference 6. Figure 7 , Figure 8 , Fig.10 and Fig.11 The following embodiments are described by taking the example that the electric drive mechanism 660 and the mechanical drive mechanism 670 are simultaneously transmission-connected to the second locking rod 620 .

[0217] In the implementation mode in which the electric drive mechanism 660 includes the electromagnet 661, the connection assembly 672 of the mechanical drive mechanism 670 and the connection assembly 672 of the electric drive mechanism 660 can be the same connection assembly 672, that is, the mechanical drive mechanism 670 reuses the connection assembly 672 of the electric drive structure, simplifying the structure of the door lock device 30. When the lock cylinder 671 rotates, the sliding member 6712 slides relative to the connection assembly 672 while rotating, so as to drive the lock cylinder 671 to move upward or downward along the set direction, and finally drive the first locking rod 610 and the second locking rod 620 to move toward or away from each other, so as to achieve locking and unlocking of the door body 20 and the box body 10.

[0218] In some embodiments, the connecting assembly 672 may further include a second connecting member 6724. The second connecting member 6724 may be in the shape of a rod, a plate, or other shapes. Exemplarily, the second connecting member 6724 may include a first portion and a second portion, the first portion may be in the shape of a column, the second portion may be in the shape of a plate, and the first portion and the second portion may be integrally arranged. The first portion may be connected to the core 6721 by fastening bolts, and the columnar first portion may improve the connection strength between the second connecting member 6724 and the core 6721. The third movable hole 6723 may be constructed in the second portion, and the plate-shaped second portion facilitates the construction of the third movable hole 6723.
