Specific meanings of the above terms in the embodiments of the present invention can be understood in specific cases by those of ordinary skill in the art.

In the description herein, references to the description of the term "one embodiment," "some embodiments," "an example," "a specific example," or "some examples," etc., mean that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of an embodiment of the invention. In this specification, the schematic representations of the terms used above are not necessarily intended to refer to the same embodiment or example. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples. Furthermore, various embodiments or examples and features of different embodiments or examples described in this specification can be combined and combined by one skilled in the art without contradiction.

Referring to fig. 1 to 10, according to an embodiment of the first aspect of the present invention, there is provided a door lock assembly for a locker, including an elastic latch tongue 101 and a latch member (not shown). The elastic bolt 101 is suitable for being mounted on one of a cabinet body 104 of a storage cabinet and a door body 105 of the storage cabinet; the lock member is adapted to be mounted to the other of the cabinet 104 and the door body 105, and is configured to be switched between a lock position and an unlock position. In the locking position, the locking member is movable relative to the resilient latch bolt 101 in the direction of rotation of the door body 105, so that the locking member compresses the resilient latch bolt 101 during locking of the door body 105. Alternatively, in the lock position, the lock member locks the resilient latch tongue 101 so that the door body 105 is maintained at the closed position. At the unlocking position, door body 105 can be freely opened or closed, but even if door body 105 is in the closed state, door body 105 cannot be locked.

According to the door lock assembly of the storage cabinet, even if the locking piece is already at the locking position when the door body 105 is not closed, due to the telescopic performance of the elastic bolt 101, the door body 105 can be ensured to be normally closed. After the door body 105 is closed, the locking piece at the locking position can enable the door body 105 to maintain the locking state, and the storage cabinet is prevented from being abnormally opened. Furthermore, when the door lock assembly is applied to the storage cabinet, even if the storage cabinet is locked by fraud, the door body 105 can still be closed to ensure the normal operation of the storage cabinet, and the reliability of the storage cabinet is ensured. In addition, since the lock member can be switched to the unlock position, the door body 105 can be freely opened and closed at this time.

Here, the "locking process" refers to a process in which the elastic latch tongue 101 is about to contact the latch member in the closing direction until the elastic latch tongue 101 is about to separate from the latch member.

The locking position of the locking piece corresponds to a state that the elastic bolt 101 can be locked so as to lock the door body 105; the lock release position corresponds to a state in which the door 105 can be freely opened and closed. For convenience of understanding the different states of the lock member, a case where the door 105 is closed will be described as an example: when the door body 105 is closed, the locking piece corresponds to a locking position in a state that the locking piece extends towards the direction of the lock tongue; the state that the lock part contracts towards the direction of keeping away from the spring bolt corresponds the unblock position.

The locking piece can adopt any structural style as long as can cooperate with the elastic bolt locking.

Referring to fig. 5, in the door lock assembly of the locker according to the embodiment of the present invention, the elastic latch 101 includes an elastic member (not shown) and a latch body 1012. The bolt body 1012 is provided with an inclined surface at one side and an elastic member at the other side, and the inclined surface is configured to form a guiding sliding fit with the locking member along the closing direction of the door body 105 at the locking position to compress the elastic member.

In connection with fig. 5, the slope satisfies: during the rotation of the door body 105, the locking piece contacts the bolt body 1012 from the edge of the inclined surface; as the door body 105 rotates in the direction of closing the door, the latch member gradually compresses the latch body 1012 and slides against the ramp; until the locking piece leaves the bolt body 1012, the bolt body 1012 extends out under the action of the elastic piece, and then the bolt body 1012 is locked by the locking piece, and at the moment, the door body 105 cannot move towards the opening direction.

According to the embodiment of the invention, the elastic bolt 101 is installed on the door body 105, and the locking piece is installed on the cabinet body 104. Since the elastic latch bolt 101 may have a simple mechanical structure, it is not necessary to change the structure of the door body 105 to mount the elastic latch bolt 101 to the door body 105. In addition, the locking member needs to be switched between the locking position and the unlocking position, and the switching between the two states often needs to be based on an external instruction, and further, for the locking member, some electronic control components or electrical elements often need to be configured, so that the locking member is installed on the cabinet body 104, and the installation of the electronic control components or the electrical elements can be facilitated.

Of course, the elastic tongue 101 may be attached to the door body 105, and the lock may be correspondingly attached to the cabinet 104. Or, the elastic bolt may be set to switch between different states based on an external instruction, and it is more reasonable to install the elastic bolt in the cabinet 104 at this time.

According to an embodiment of the present invention, the door lock assembly of the storage cabinet further comprises a mounting box 103, and the locking member is fixed to the cabinet body 104 through the mounting box 103, so that the locking member can be reliably mounted.

In one embodiment, referring to fig. 6 and 7, the mounting case 103 includes a fixing portion 1031, a mounting portion 1032, and a receiving groove 1033. Wherein the fixing part 1031 is used for fixing the mounting box 103 to the cabinet 104; the mounting portion 1032 is used for mounting a lock member; the receiving groove 1033 is located between the fixing portion 1031 and the mounting portion 1032, and is used for receiving an electric component or an electric control part of the latch member, and the like.

As can be seen from fig. 6 and 7, a plurality of connecting holes are provided on the fixing portion 1031, and the connecting holes may be, but are not limited to, threaded holes, so that the fixing portion 1031 may be fixed to the cabinet 104 by using screws.

In one embodiment, the cables required for the locker door lock assembly can be disposed in the receiving slots 1033; for another example, the electric control component of the locking member can be disposed in the receiving groove 1033. Of course, the receiving groove 1033 can be used for mounting other parts required by the cabinet, not limited to the electric components including the cable, but also not limited to the electric control part of the locking member.

The electronic control component included in the lock member refers to a component which controls the state of the lock member (in the case of no specific reference, the state of the lock member refers to at least one of the locked position and the unlocked position) to be switched based on an external command.

According to an embodiment of the present invention, in conjunction with fig. 5 and 6, the mounting portion 1032 is formed with a mounting groove 10321, the mounting groove 10321 is used for mounting the lock body 102, and the lock body 102 includes the lock case 1021 and the above-mentioned locking member. The lock body 102 may take the form of an electrically controlled lock, although other forms may be used.

In the locked position, the lock housing 1021 and the locking member form a locking slot 1022 (in fig. 5, the position of the locking slot 1022 is indicated for clarity, and the locking member is in the unlocked position), and the locking slot 1022 is configured to receive an elastic bolt when the door 105 is in the closed state to prevent the door 105 from rotating.

Wherein, when the bolt body 1012 is detected to enter the locking groove 1022, the locking piece can be controlled to be switched to the locking position. In this case, a sensing component may be correspondingly disposed in the locking groove 1022 to ensure the accuracy of detection.

In addition, the mounting portion 1032 is further formed with an escape notch 10322, and the provision of the escape notch 10322 can ensure that the elastic latch tongue 101 does not interfere with the mounting portion 1032 of the mounting box 103 with the opening and closing of the door 105 even if the door 105 is deformed.

It can be seen from fig. 5 that the lock case 1021 has a lock case position-limiting portion 10211 for fixing with a region outside the installation slot 10321, and further, most of the structure of the lock case 1021 is hidden in the installation slot 10321, and meanwhile, the lock case 1021 can be positioned by the lock case position-limiting portion 10211, which is convenient for the lock case 1021 to be disassembled and assembled. A connection hole may be formed in the lock case limiting portion 10211 of the lock case 1021, and the connection hole corresponds to the connection hole in the mounting portion 1032, so as to ensure the fixation between the lock case 1021 and the mounting portion 1032.

In one embodiment, in conjunction with fig. 5, the resilient latch bolt 101 includes a bolt body 1012 and a mount 1013 for mounting the bolt body 1012. The elastic member may be a spring disposed in the installation seat 1013, one end of the spring is connected to the tongue body 1012, and the other end of the spring is connected to the bottom of the installation seat 1013, so that when external pressure is applied, the tongue body 1012 compresses the spring and contracts into the installation seat 1013; when the pressure of the external pressure to the elastic latch 101 is removed, the latch body 1012 is extended out of the installation seat 1013 by the restoring force of the spring.

In one embodiment, mount 1013 includes mount stop 10131. When the elastic latch tongue 101 is mounted to the door body 105 and the mounting hole 1064 is formed in the door body 105 (e.g., the handle 106 of the door body 105), the mounting seat 1013 and the mounting hole 1064 are engaged with each other by the mounting seat stopper 10131.

The door lock assembly of the storage cabinet according to the embodiment of the invention may comprise at least one of a controller (belonging to one form of the above-mentioned electric control component) and a sensing component, and both the controller and the sensing component may be attached to the storage cabinet independently of the door lock assembly. The operation principle of the controller and the sensing component will be described in detail below.

In one embodiment, a door lock assembly for a stowage bin includes a controller for controlling switching of the state of a latch.

The controller may be installed in the aforementioned accommodation groove 1033, or may be installed independently of the aforementioned mounting box 103, as long as the controller can control the locking member to switch the states. When the controller was installed in holding tank 1033, can leave the factory at the lock subassembly before, all integrate in mounting box 103 with controller and locking piece, and then follow-up only need fixed mounting box 103 just fixed the controller simultaneously, its suitability is higher.

According to the embodiment of the invention, the controller may control the state switching of the lock member based on the relative positional relationship between the door body 105 and the cabinet body 104, or may control the state switching of the lock member based on other external instructions. The other instruction includes a door closing instruction sent by a mobile terminal of the locker, a settlement instruction sent by the mobile terminal of the locker, a prompt instruction sent when the locker receives a code scanning requirement, a prompt instruction sent when the locker identifies information such as a human face or a fingerprint, and the like.

In one embodiment, the door lock assembly includes a sensing component configured to emit a sensing signal based on the relative positional relationship between the cabinet 104 and the door body 105. The controller controls the locking piece to switch between the locking position and the unlocking position based on the sensing signal.

For example, the sensing part may include a hall sensor and a magnetic member corresponding to the hall sensor. When the relative position relationship between the door body 105 and the cabinet body 104 changes, the distance between the magnetic part and the hall sensor changes, and then the hall sensor can sense the change of the magnetic field around the hall sensor in time and send the change to the controller. At this time, the controller may send a control signal to effect the switching of the state of the lock. When the door body 105 approaches the cabinet body 104 and is finally closed, the controller controls the locking member to be switched to the locking position.

Wherein the magnetic member may, but need not, take the form of a magnet. Magnetic elements refer to objects that react in some way to a magnetic field and do not require themselves to be capable of generating a magnetic field. The magnetic part can be prepared from any magnetic material, such as magnets, low-carbon steel and the like; of course, the first magnetic member may be an energized coil.

In one embodiment, the hall sensor may include a spring plate and a circuit, the spring plate is matched with the magnet, and when the magnet is far away from or close to the spring plate, the spring plate springs up, and the current of the circuit changes. In this case, the controller controls the state switching of the lock member based on the change in the current. Of course, the specific type of hall sensor is not limited by the examples herein.

Among them, the hall sensor may be fixed to one of the above-mentioned mounting case 103 and the mount 1013, and the magnetic member may be fixed to the other of the above-mentioned mounting case 103 and the mount 1013.

It should be noted that the kind of the sensing component is not limited by the examples herein. For example, the sensing component may also be a pressure sensor or an infrared sensor, etc. When the sensing component is a pressure sensor, the sensing component may be disposed on the door frame or the door frame of the cabinet 104. During the closing process of the door body 105, the sensing part senses pressure and controls the locking piece. When the sensing part is an infrared sensor, whether the door body 105 is about to be closed is judged by sensing the position change of the door body 105.

The working process of the storage cabinet is explained by taking a sales cabinet as an example:

when the mobile terminal (for example, a mobile phone) scans codes of the storage cabinet, or the storage cabinet identifies a human face or a fingerprint, the user initiates a purchase demand, the controller sends a door opening signal at the moment, the locking piece is switched to an unlocking position based on the door opening signal, then the door body 105 is unlocked at the moment, and the sales counter can be opened.

When the user takes the goods from the storage cabinet and the mobile terminal deducts money and settles accounts, which means that the current transaction is completed, the controller sends a door locking signal, the locking piece is switched to a locking position based on the door locking signal, and then the door body 105 is locked at the moment, so that the goods are prevented from being lost. Or, when the mobile terminal does not select settlement, but the door 105 of the sales counter is closed, which means that the user has completed the current transaction, the controller may send a door locking signal, switch the locking member to the locking position based on the door locking signal, and complete the deduction of money from the mobile terminal based on the door locking signal.

Since there may be repentance after the user closes the door, in the case of sending the door locking signal based on the closing of the door 105, a certain delay time may be set, for example, the door locking signal is sent after the door 105 is closed, and the user may open the door 105 again within the delay time to replace the goods. Wherein, the delay time is not too long, otherwise, the transaction risk is brought. For example, the delay time period may be 0.5 seconds to 2 seconds, although other suitable values may be selected.

According to the embodiment of the second aspect of the invention, a storage cabinet is provided, which comprises the door lock assembly, a cabinet body 104 and a door body 105.

In fig. 3 and 4, the door lock assembly is disposed outside the storage cabinet, so that condensation (for the storage cabinet with a refrigeration function) can be prevented from occurring at the door lock assembly, and the arrangement of the door lock assembly hardly affects the original structure of the storage cabinet. Of course, the door lock assembly can be arranged inside the storage cabinet, so that the door lock assembly is prevented from being damaged, and the safety of the storage cabinet is guaranteed.

In one embodiment, the sensing component is independent of the door lock assembly, and the storage cabinet further comprises a sensing component configured to send a sensing signal based on the relative position between the cabinet 104 and the door 105, and the locking component is configured to switch between the locking position and the unlocking position based on the sensing signal.

According to an embodiment of the present invention, the elastic latch tongue 101 or the latch bolt is installed at an opening side of the door body 105, and the latch tongue or the latch bolt is installed at a middle portion of the door body 105 in a height direction of the door body 105. In this case, the deformation stress point of the door body 105 under the condition that the door body 105 is opened by external force when the locker door body 105 is locked can be changed, so that the deformation of the door body 105 is reduced. Specifically, break a body 105 increase the clearance between the body 105 and the cabinet body 104 off with the fingers and thumb from the outside as someone to when trying to let the hand get into the cabinet body 104 and take the goods, this kind of set up in the locker and open the door lock subassembly in the side middle part and can guarantee that a body 105 deflection is little, and then the clearance between the body 105 and the cabinet body 104 is very little, guarantees that the locker has the theftproof function.

Here, "the middle of door body 105 in the height direction of door body 105" refers to an area between the top and bottom of door body 105, that is, "the middle" is a relative concept, and does not refer to the middle of door body 105 in the height direction. The "open side" of door body 105 corresponds to the left side of fig. 3, and is relative to the rotational side of door body 105. Specifically, the side which is not always away from the cabinet 104 refers to the rotation side of the door 105, and the side which can be opened and closed relative to the cabinet 104 refers to the opening side of the door 105.

According to the storage cabinet provided by the embodiment of the invention, the elastic bolt 101 or the locking piece is positioned in an area which is 0.3h to 0.7h away from the bottom of the door body 105, and h is the height of the door body. Furthermore, the cabinet can be pried from the top or the bottom of the door body 105, so that the door body 105 can be prevented from being deformed. The elastic spring bolt or the locking piece is positioned at a distance from the bottom of the door body

According to the storage cabinet of the embodiment of the invention, when the latch or the locking piece is installed in the middle of the door body 105 along the height direction of the door body 105, the sensing part of the storage cabinet can be arranged at the top or the bottom of one of the cabinet body 104 and the door body 105. Because the positions of the sensing component and the door lock assembly do not correspond to each other, the position of the sensing component is not easy to find, and the lock can be prevented from being cheated at the moment.

Of course, the induction component can be arranged at other positions of the storage cabinet, and the induction component can be hidden in the storage cabinet, so that a better anti-cheating lock effect is achieved.

Taking the magnetic induction component as an example, the existing storage cabinet has the situation that a user maliciously holds the magnetic piece to cheat the lock. The storage cabinet provided by the invention can hide the sensing component, so that the lock can be prevented from being cheated.

According to the storage cabinet of the embodiment of the invention, the opening side of the door body 105 is provided with the handle 106, and one of the elastic bolt 101 and the locking piece is arranged on the handle 106. Furthermore, the door lock assembly can be installed without changing the basic structure of the original door body 105, and the door lock assembly can be replaced only by replacing the handle 106.

In one embodiment, referring to fig. 8 to 10, the door body 105 includes a side plate, and the handle 106 includes a bridging portion 1061 bridging the side plate, an operating portion 1062 for operating an opening and closing state of the door body 105, and a reinforcing portion 1063 formed between the bridging portion 1061 and the operating portion 1062. The operation part 1062 may be formed with a handle slot, or the operation part 1062 may be formed with another structure for opening and closing the door.

Among them, since the handle 106 is mounted to the side plate of the door body 105 through the lap portion 1061, the structural strength of the door body 105 can be enhanced to the maximum extent.

Of course, the structure of the handle 106 is not limited to the examples provided herein, as long as the installation of the door lock assembly can be facilitated and the door opening operation can be ensured.

In one embodiment, the latch member is generally disposed on the cabinet 104, and for the elastic latch tongue 101 with a simple structure, the latch member is mounted on the handle 106 of the door 105, since the latch member generally needs to be disposed with an electric control component or needs to be connected with an electric component. At this time, the reinforcing part 1063 of the handle 106 is hollow and forms an expansion space of the resilient latch 101

In one embodiment, handle 106 extends from the top of door body 105 to the bottom of door body 105. Under the condition, the door body 105 can be operated by people with different heights and ages conveniently, the structural strength of the door body 105 can be guaranteed, the deformation of the door body 105 is reduced, and the anti-theft function of the storage cabinet is improved.

According to an embodiment of the present invention, the storage cabinet is a sales counter, a courier cabinet, or a showcase, and is not limited to the examples herein.
