Description

Technical Field

[0001] The present application relates to the technical field of distribution cabinet control, and more specifically, to a control method and system for an in-vehicle distribution cabinet. Background Art

[0002] Currently, in cities and industrial parks, small unmanned vehicles such as unmanned delivery vehicles, unmanned retail vehicles, and unmanned cleaning vehicles have begun to appear in people's daily lives. These unmanned vehicles can replace humans to perform certain tasks, spreading the concept of contactless delivery and contactless economy. In semi-closed and closed industrial parks and fixed areas beside certain roads, some unmanned vending vehicles have also started commercial operations.

[0003] Compared with traditional fixed express storage cabinets, the in-vehicle distribution cabinets of existing unmanned vehicles have higher requirements for timeliness and safety, require higher loading and unloading efficiency. At the same time, if the unmanned vehicle moves when the cabinet door is opened, it may cause safety accidents. Summary of the Invention

[0004] The main purpose of the present invention is to provide a control method for an in-vehicle distribution cabinet, aiming to solve the technical problems of poor safety, low convenience and low work efficiency for staff operation of the in-vehicle distribution cabinet in the prior art.

[0018] Further, the on-vehicle delivery cabinet control method further includes: after triggering a control instruction to open the cabinet door corresponding to the misclosed grid opening, identify the corresponding information of the cabinet door closed before triggering the control instruction to open the cabinet door corresponding to the misclosed grid opening, and sort the cabinet doors according to the corresponding information. Establish a corresponding relationship between the number of times of triggering the control instruction to open the cabinet door corresponding to the misclosed grid opening and the sorted cabinet doors to open the corresponding cabinet doors.

[0019] Further, the on-vehicle delivery cabinet control method further includes:

[0020] After triggering a control instruction to open the cabinet door corresponding to the misclosed grid opening, identify the sequence of the cabinet doors closed before triggering the control instruction to open the cabinet door corresponding to the misclosed grid opening, and arrange them in order from near to far according to the time interval; establish a correspondence between the number of times of triggering the control instruction to open the cabinet door corresponding to the misclosed grid opening and the misclosed cabinet doors arranged in order from near to far according to the time interval to open the corresponding cabinet doors.

[0021] Further, the on-vehicle delivery cabinet control method further includes: after triggering a control instruction to open the cabinet door corresponding to the misclosed grid opening, identify the cargo information in the grid opening corresponding to the cabinet door closed before triggering the control instruction to open the cabinet door corresponding to the misclosed grid opening, and sort the cabinet doors according to the cargo information; establish a correspondence between the number of times of triggering the control instruction to open the cabinet door corresponding to the misclosed grid opening and the sorted cabinet doors to open the corresponding cabinet doors.

[0022] Further, the on-vehicle delivery cabinet control method further includes: continuously trigger the control instruction to open the cabinet door corresponding to the misclosed grid opening for more than a predetermined time to open all cabinet doors or all misclosed cabinet doors.

[0023] In addition, the present invention also provides a vehicle-mounted delivery cabinet control system. Among them, the vehicle-mounted delivery cabinet includes a cabinet body provided with a plurality of compartments and cabinet doors corresponding to each of the compartments. Each of the compartments matches a target location. The vehicle-mounted delivery cabinet control system includes:

[0024] A status information acquisition module, configured to acquire the initial status of the compartment matched with the target location;

[0025] An actuator, configured to unlock the cabinet door from the cabinet body or lock the cabinet door to the cabinet body. After the cabinet door is unlocked from the cabinet body and before loading and / or unloading the compartment, keep the cabinet door and the cabinet body at a second preset angle. When loading and / or unloading the compartment, the cabinet door remains at a first preset angle relative to the cabinet body, and the first preset angle is greater than the second preset angle;

[0026] A total control unit, which is signal-connected to the status information acquisition module and the actuator.

[0027] Further, the status information acquisition module includes a switch door status detection sensor and a cargo detection sensor, and the vehicle-mounted delivery cabinet control system further includes a misclosed compartment opening control unit;

[0028] The misclosed compartment opening control unit is signal-connected to the total control unit, and the misclosed compartment opening control unit is configured to receive a control instruction for triggering the opening of the cabinet door corresponding to the misclosed compartment;

[0029] The actuator includes an electric control switch door actuator for unlocking or locking the cabinet door to / from the cabinet body, and electronic components and / or mechanical components for keeping the cabinet door at the first preset angle.

[0030] Further, the electric control switch door actuator includes a lock hook hinged to the cabinet door, a lock catch cooperating with the lock hook is provided on the cabinet body, and the electric control switch door actuator further includes a driving mechanism, a sliding mechanism, and an unlocking mechanism for driving the lock hook to swing. Both the unlocking mechanism and the sliding mechanism are connected to the driving mechanism.

[0031] The beneficial effects of the vehicle-mounted delivery cabinet control method and the vehicle-mounted delivery cabinet control system provided by this application are as follows:

[0032] In the vehicle-mounted delivery cabinet control method provided by the present invention, on the one hand, after the cabinet door is unlocked from the cabinet body, the cabinet door still remains in a closed state at a second preset angle. Therefore, when the vehicle-mounted delivery cabinet moves with the vehicle (such as a driverless vehicle), the cabinet door will not open, effectively preventing related safety accidents. For example, to avoid blocking and scraping accidents when the vehicle starts or when vehicles and pedestrians pass by. In addition, since the cabinet door can be opened to a first preset angle and maintained at the first preset angle, there is no need for the loading and unloading personnel to hold the door open with one hand and pick up and place goods with the other hand, thus improving the operation convenience and work efficiency of the staff. Moreover, by identifying the misclosed compartments, the cabinet door corresponding to the misclosed compartment can be automatically controlled to open, efficiently opening the misclosed cabinet door.

[0033] In a further solution, the vehicle-mounted delivery cabinet control system adopts an electric control switch door actuator that unlocks or locks the cabinet door to the cabinet body, facilitating the automatic closing of the cabinet door. BRIEF DESCRIPTION OF THE DRAWINGS

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, "a plurality of" means two or more unless otherwise specifically defined.

[0048] In order to illustrate the technical solutions described in the present application, the following will be described in detail with reference to specific drawings and embodiments.

[0049] See Figure 1 , an embodiment of the present invention provides a control method for a vehicle-mounted delivery cabinet, which is particularly suitable for but not limited to an unmanned vehicle express cabinet. The vehicle-mounted delivery cabinet includes a cabinet body provided with a plurality of compartments and cabinet doors corresponding to each of the compartments. Each of the compartments is matched with a target location. The control method for the vehicle-mounted delivery cabinet includes:

[0050] Control the compartment 3 matched with the target location to trigger an unlocking signal;

[0051] Unlock the cabinet door 2 corresponding to the compartment 3 that triggers the unlocking signal from the cabinet body 1;

[0052] Open the cabinet door 2 relative to the cabinet body 1 to a first preset angle and keep the cabinet door 2 at the first preset angle;

[0053] Before the cabinet door 2 is unlocked and before the cabinet door 2 is opened to the first preset angle, the cabinet door 2 remains at a second preset angle relative to the cabinet body 1, where the second preset angle is smaller than the first preset angle. In fact, the second preset angle is as small as possible. When the cabinet door 2 remains at the second preset angle relative to the cabinet body 1, it can still be understood as being in a closed state;

[0054] After the first preset angle, perform the following operations:

[0055] After loading and / or unloading the goods in the compartment 3, close the cabinet door 2 and lock the cabinet door 2 to the cabinet body 1;

[0056] When the cabinet door 2 is accidentally closed, compare the status of the compartment 3 to identify the accidentally closed compartment 3;

[0057] Trigger a control instruction to open the cabinet door 2 corresponding to the accidentally closed compartment 3 to automatically control the opening of the cabinet door 2 corresponding to the accidentally closed compartment 3.

[0058] In the control method for the vehicle-mounted delivery cabinet provided by the embodiment of the invention, on the one hand, after the cabinet door 2 is unlocked from the cabinet body 1 but the cabinet door 2 still remains in the closed state at the second preset angle, the cabinet door 2 will not open when the vehicle-mounted delivery cabinet moves with the vehicle (such as an unmanned vehicle), effectively preventing related safety accidents. For example, to avoid blocking and rubbing accidents when the vehicle starts or when vehicles and pedestrians pass by. In addition, since the cabinet door 2 can be opened to the first preset angle and the cabinet door 2 can be kept at the first preset angle, there is no need for the loading and unloading personnel to hold the door open with one hand and pick up and place the goods with the other hand, thus improving the operation convenience and work efficiency of the staff. And the accidentally closed compartment 3 can be identified, and the cabinet door 2 corresponding to the accidentally closed compartment 3 can be automatically controlled to open, efficiently and automatically opening the accidentally closed cabinet door 2.

[0059] According to specific embodiments of the present invention, the opening of the cabinet door 2 corresponding to the target location is achieved by at least one of the following methods: automatically opening the cabinet door corresponding to the compartment after reaching the target location; the on-site user opens the cabinet door corresponding to the compartment through the APP or a Bluetooth, WIFI key, or password lock; opening the cabinet door corresponding to the compartment through a button or touch operation; in addition, other opening methods are not excluded.

[0060] According to an embodiment of the present invention, the first preset angle is greater than or equal to 90°. Such an opening angle can effectively ensure the convenience of staff for picking up and delivering goods. Therefore, the first preset angle is as large as possible, and further preferably greater than or equal to 100° and less than or equal to 120°. Of course, even a solution where the first preset angle is less than 90° will fall within the protection scope of the present invention. It should be understood that the second preset angle is preferably a suitable small angle, such as less than 3° or less than 5°, etc.

[0061] According to an embodiment of the present invention, when the cabinet door 2 is maintained at the first preset angle, an external force that does not cause the opening angle of the cabinet door 2 relative to the cabinet body 1 to be greater than the first preset angle cannot drive the cabinet door 2. Such an external force is, for example, a certain level of wind force, or a collision force when accidentally touched by an operator or other person or object.

[0062] According to a preferred embodiment of the present invention, both opening the cabinet door 2 to a preset angle and closing the cabinet door 2 are manually operated. This can simplify the relevant equipment structure. Of course, if an automated control solution for opening the cabinet door 2 to a preset angle and closing the cabinet door 2 is adopted, it will also fall within the protection scope of the present invention.

[0063] According to an embodiment of the present invention, before the unlocking signal of the compartment 3 corresponding to the control target location is triggered, the on-vehicle delivery cabinet control method further includes:

[0064] Identifying the target location information to determine whether the current location reached is for picking up goods or delivering goods;

[0065] Detecting and obtaining the initial state of the compartment 3 matching the target location, such as determining whether there is goods in the compartment 3, whether the cabinet door 2 corresponding to the compartment 3 is closed or open, locked or unlocked, etc.

[0066] According to an embodiment of the present invention, the logic for identifying a misclosed compartment can be specifically:

[0067] The misclosed compartment opening control unit 7 includes an operation button installed on the on-vehicle delivery cabinet. When the operator discovers a misclosed compartment, pressing the operation button once, the system will identify the first closed door as the misclosed door from the moment the button is triggered. Pressing it again will identify the second misclosed door. In principle, it can be inferred in sequence, but in fact, only identifying twice is enough. Setting an operation of long pressing the button is for fully opening the cabinet door;

[0068] Trigger a control instruction to open the cabinet door 2 corresponding to the misclosed compartment 3, so as to automatically control the opening of the cabinet door 2 corresponding to the misclosed compartment 3. It is possible to trigger a control instruction to open the cabinet door 2 corresponding to the misclosed compartment 3 automatically after identifying the misclosed compartment 3 or manually trigger a related operation instruction. During specific operation, the cabinet door 2 corresponding to the misclosed compartment 3 should be quickly opened, so as to avoid the situation that it is difficult to open the cabinet door 2 or it is very complicated to open the cabinet door 2 after the cabinet door 2 is misclosed, and improve the user experience. Specifically, it can completely automate the control to open the cabinet door 2 corresponding to the misclosed compartment 3, or wait for an operation instruction to open it.

[0069] According to an embodiment of the present invention, after triggering a control instruction to open the cabinet door 2 corresponding to the misclosed compartment 3, identify the corresponding information of the cabinet door 2 that was closed before triggering the control instruction to open the cabinet door 2 corresponding to the misclosed compartment 3, and sort the cabinet doors 2 according to the corresponding information. Establish a corresponding relationship between the number of times of triggering the control instruction to open the cabinet door 2 corresponding to the misclosed compartment 3 and the sorted cabinet doors 2 to open the corresponding cabinet doors 2.

[0070] As a specific embodiment of the above embodiment, the on-vehicle delivery cabinet control method further includes:

[0071] After triggering a control instruction to open the cabinet door 2 corresponding to the misclosed compartment 3, identify the sequence of the cabinet doors 2 that were closed before triggering the control instruction to open the cabinet door 2 corresponding to the misclosed compartment 3, and arrange them in order from near to far at time intervals. Of course, it can also be arranged in the order from far to near; establish a correspondence between the number of times of triggering the control instruction to open the cabinet door 2 corresponding to the misclosed compartment 3 and the misclosed cabinet doors 2 arranged in order from near to far at time intervals to open the corresponding cabinet doors 2. For example, if the control instruction to open the cabinet door 2 corresponding to the misclosed compartment 3 is triggered once, then open the cabinet door 2 that was misclosed most recently. If the control instruction to open the cabinet door 2 corresponding to the misclosed compartment 3 is triggered twice, then open the cabinet door 2 that was misclosed the time before the most recently misclosed cabinet door 2, and so on.

[0072] As another specific embodiment in the above embodiments, after triggering the control instruction to open the cabinet door 2 corresponding to the misclosed compartment 3, identify the cargo information in the compartment 3 corresponding to the cabinet door 2 that was closed before triggering the control instruction to open the cabinet door 2 corresponding to the misclosed compartment 3 (i.e., an embodiment of the corresponding information of the cabinet door 2 mentioned above), and arrange the cabinet doors 2 in sequence according to the cargo information; open the corresponding cabinet doors 2 by the number of times of triggering the control instruction to open the cabinet door 2 corresponding to the misclosed compartment 3 corresponding to the arranged cabinet doors 2. Among them, the cargo information can specifically refer to information such as the brand of the cargo, the price of the cargo, the putting time, the importance level, etc., or the status information of whether there is cargo, so as to establish a preferred level order for the information of the cargo. Trigger the control instruction to open the cabinet door 2 corresponding to the misclosed compartment 3 once, then open the cabinet door 2 of the compartment 3 corresponding to the highest priority level of the cargo, and so on. Establishing the corresponding relationship with the corresponding information of the cabinet door 2 can be completely customized according to different needs.

[0073] According to an embodiment of the present invention, the on-vehicle delivery cabinet control method further includes: triggering the control instruction to open the cabinet door 2 corresponding to the misclosed compartment 3 to open all cabinet doors 2 or all misclosed cabinet doors 2. That is to say, the present invention can not only precisely control the opening of the required misclosed cabinet doors 2, but also can open all misclosed cabinet doors 2 at one time through one instruction. In addition, since all misclosed cabinet doors 2 are opened, the cabinet door 2 corresponding to the misclosed compartment 3 is also opened, so this solution also belongs to the category of controlling the opening of the cabinet door 2 corresponding to the misclosed compartment 3. By adding such an operation, all cabinet doors 2 or all misclosed cabinet doors 2 can be quickly and conveniently opened, so as to meet the more efficient door-opening requirements.

[0074] According to a specific embodiment of the present invention, the on-vehicle delivery cabinet control method further includes: continuously triggering the control instruction to open the cabinet door 2 corresponding to the misclosed compartment 3 for a predetermined time or more to open all misclosed cabinet doors 2. For example, if the control instruction to open the cabinet door 2 corresponding to the misclosed compartment 3 is triggered for more than 5s, then all misclosed cabinet doors 2 are opened at one time. If the control instruction to open the cabinet door 2 corresponding to the misclosed compartment 3 is triggered less than 5s each time, only the action of opening the required cabinet door 2 is executed.

[0075] See Figure 2 and Figure 3 Corresponding to the above on-vehicle delivery cabinet control method, the present invention also provides an on-vehicle delivery cabinet control system. The on-vehicle delivery cabinet includes a cabinet body 1 provided with a plurality of compartments 3 and cabinet doors 2 corresponding to each compartment 3. Each compartment 3 matches a target location. Among them, the on-vehicle delivery cabinet control system includes:

[0076] A status information acquisition module 4, configured to acquire the initial status of the compartment 3 matched by the target location;

[0077] The actuator 5 is used to unlock the cabinet door from the cabinet body or to lock the cabinet door to the cabinet body 1, and to keep the cabinet door 2 and the cabinet body 1 at a second preset angle after the cabinet door 2 is unlocked from the cabinet body 1 and before the compartment 3 is loaded and / or unloaded. When the compartment 3 is loaded and / or unloaded, the cabinet door 2 is kept at a first preset angle relative to the cabinet body 1, and the first preset angle is greater than the second preset angle;

[0078] The general control unit 6 can adopt a known control circuit board, PLC, etc., can be connected to a background server for identifying target location information, and can also be connected to a voice control system, a lighting system, and a cabinet disinfection system, etc., which will not be described in detail here. It is connected to the status information acquisition module 4 and the actuator 5 by signal, so that according to the relevant information obtained by the status information acquisition module 4, control instructions can be sent to the actuator 5 in a targeted manner to operate the cabinet door 2 to unlock or lock it in the cabinet 1, operate the cabinet door 2 to maintain a preset angle, etc.

[0079] According to one embodiment of the present invention, the status information acquisition module 4 includes a door opening and closing status detection sensor 41 and a cargo detection sensor 42, which are used to detect and obtain the initial state of the compartment 3 used at the target location, compare the state of the compartment 3 when the cabinet door 2 is mistakenly closed, identify the mistakenly closed compartment 3, etc. The door opening and closing status detection sensor 41 and the cargo detection sensor 42 can both adopt known technologies, which will not be elaborated here.

[0080] According to one embodiment of the present invention, the vehicle-mounted distribution cabinet control system further includes a mis-closed compartment opening control unit 7;

[0081] The mistakenly closed compartment opening control unit 7 is connected to the main control unit 6 by signal. The mistakenly closed compartment opening control unit 7 is used to receive a control instruction for triggering the opening of the cabinet door 2 corresponding to the mistakenly closed compartment 3. Specifically, the mistakenly closed compartment opening control unit 7 includes an operation button installed on the vehicle-mounted delivery cabinet. For example, pressing the button once will open the cabinet door 2 that was most recently mistakenly closed. Pressing the button twice will open the cabinet door 2 that was mistakenly closed before the most recent mistakenly closed cabinet door 2, and so on. Alternatively, pressing the button for more than 5 seconds will open all the mistakenly closed cabinet doors 2 at once. If the button is pressed for less than 5 seconds, only the action of opening the required cabinet door 2 will be performed.

[0082] According to one embodiment of the present invention, the actuator 5 includes an electric door switch actuator for unlocking or locking the cabinet door 2 to the cabinet body 1 and an electronic component and / or mechanical component for maintaining the cabinet door 2 at a first preset angle. The electric door switch actuator adopts known technology, which will not be described in detail here. The mechanical component can be various known technologies, such as various known mechanisms containing torsion springs, springs, etc. that can keep two hinged objects (cabinet door 2 and cabinet body 1 hinged to each other) at a certain angle to each other, which will not be repeated here.

[0083] As a specific embodiment, see Figures 4 to 7 , the detailed structure and working principle of the electric control switch door actuator are as follows:

[0084] The hinge between the cabinet door 2 and the cabinet body 1 can be achieved by a door shaft 8 or a hinge, etc. The electric-controlled door switch actuator includes a lock hook 9 hinged on the cabinet door 2, and a lock buckle 10 cooperating with the lock hook 9 is provided on the cabinet body 1. The electric-controlled door switch actuator also includes a driving mechanism, a sliding mechanism 22, and an unlocking mechanism 18 for driving the lock hook 9 to swing. The unlocking mechanism 18 and the sliding mechanism 22 are both connected to the driving mechanism, and a support rod 16 for driving the cabinet door 2 to open the door is provided between the sliding mechanism 22 and the cabinet body.

[0085] The electric control door opening and closing actuator uses the driving mechanism to provide power to drive the unlocking mechanism 18 and the sliding mechanism 22 to move. The unlocking mechanism 18 drives the lock hook 9 to swing, and the sliding mechanism 22 drives the support rod 16 to move. When the lock hook 9 is connected to the lock buckle 10, the cabinet door 2 can be locked, and the lock hook 9 can be unlocked after being separated from the lock buckle 10; since the length of the support rod 16 itself will not change, and the two ends are respectively connected to the cabinet body and the sliding mechanism 22, after the unlocking mechanism 18 completes the unlocking, the sliding mechanism 22 slides to drive the support rod 16 to move with the sliding mechanism 22, and the position of the connection between the support rod 16 and the sliding mechanism 22 relative to the cabinet door 2 will change, thereby changing the angle of the cabinet door 2, that is, realizing the opening and closing of the cabinet door 2, with a high degree of automation, and no need for the user to manually close the door.

[0086] Furthermore, the sliding mechanism 22 includes a sliding sleeve 23 sleeved on the driving mechanism and a slip ring 24 sleeved on the sliding sleeve 23 and capable of sliding relative to the sliding sleeve 23. The driving mechanism is provided with a stopper 12 (the stopper 12 preferably adopts a stopper nut, which has a reliable structure and is convenient for disassembly, assembly and adjustment). The side of the sliding sleeve 23 away from the stopper 12 is provided with a stopper 25 for driving the slip ring 24 to slide, and an elastic buffer 13 is provided between the stopper 12 and the slip ring 24. When the driving mechanism drives the unlocking mechanism 18 to unlock, the sliding sleeve 23 slides under the drive of the driving mechanism. At this time, the stopper 25 does not contact the slip ring 24, and the slip ring 24 remains motionless under the action of the elastic buffer 13. Accordingly, the support rod 16 does not move, and the cabinet door 2 remains motionless. After the unlocking mechanism 18 completes the unlocking, the driving mechanism continues to drive the sliding sleeve 23 to slide. At this time, the limiting part 25 contacts the sliding ring 24. When the force applied by the limiting part 25 on the sliding ring 24 exceeds the elastic force of the elastic buffer 13, the sliding ring 24 can be driven to move. The elastic buffer 13 is compressed, and the position of the connection between the support rod 16 and the sliding mechanism 22 relative to the cabinet door 2 will change. The cabinet door 2 is opened under the action of the support rod 16, and the action of unlocking first and then opening the door is automatically realized. The structure is simple and effective.

[0087] Further, the sliding sleeve 23 is provided with a guiding convex part, and the inner side of the sliding ring 24 is provided with a guiding groove that cooperates with the guiding convex part. Through the cooperation of the guiding convex part and the guiding groove, the relative rotation of the sliding ring 24 with respect to the sliding sleeve 23 can be prevented, and at the same time, a guiding function is provided to ensure smooth movement and high movement accuracy when the sliding sleeve 23 and the sliding ring 24 slide relative to each other.

[0088] As a preferred embodiment, one end of the support rod 16 is hinged to the sliding ring 24, and the other end is hinged to the cabinet body. The structure is simple and reasonable, which is beneficial to ensuring smooth opening and closing of the door.

[0089] As a preferred embodiment, the elastic buffer 13 is a helical spring and is sleeved on the driving mechanism. The driving mechanism can provide a guiding function for the elastic buffer 13, which is beneficial to preventing the elastic buffer 13 from being twisted after being compressed.

[0090] As a preferred embodiment, the driving mechanism includes a driving motor 11 and a lead screw 15 connected to the driving motor 11. The inner side of the sliding sleeve 23 is provided with a threaded hole that cooperates with the lead screw 15. When opening or closing the cabinet door 2, the driving motor 11 drives the lead screw 15 to rotate, and the sliding sleeve 23 cooperates with the lead screw 15 through the threaded hole to achieve sliding on the lead screw 15. The structure is simple and the technology is mature and reliable.

[0091] Further, the unlocking mechanism 18 includes a connecting rod 19 and a lead screw nut 20 provided on the lead screw 15. One end of the connecting rod 19 is hinged to the lead screw nut 20, and the other end is hinged to the locking hook 9. When the cabinet door 2 needs to be unlocked, the driving motor 11 drives the lead screw 15 to rotate, the lead screw nut 20 moves towards the side where the driving motor 11 is located, the connecting rod 19 acts under the drive of the lead screw nut 20, and the locking hook 9 is pulled by the connecting rod 19 to rotate and separate from the locking buckle 10; conversely, when it is necessary to lock the cabinet door 2, the driving motor 11 drives the lead screw 15 to rotate in the reverse direction, the lead screw nut 20 moves towards the side where the locking hook 9 is located, the connecting rod 19 moves under the drive of the lead screw nut 20, and the locking hook 9 is pushed by the connecting rod 19 to rotate in the reverse direction and connect with the locking buckle 10. The structure is simple and the reliability is good.

[0092] As a preferred embodiment, the unlocking mechanism 18 further includes an electric control switch door actuator torsion spring 21 provided on the hinge shaft of the locking hook 9 and the cabinet door 2. When the locking hook 9 needs to be opened, the electric control switch door actuator torsion spring 21 can provide a certain elastic force to assist the locking hook 9 to swing and separate from the locking buckle 10.

[0093] As a preferred embodiment, the support rod 16 is of a U-shaped structure and the opening faces the cabinet door 2. The driving mechanism is located between the two side walls 17 of the support rod 16, which can save space and avoid excessive occupation of the loading space inside the cabinet body.

[0094] 1) Door opening process: First, the driving motor 11 drives the lead screw 15 to rotate. The lead screw nut 20 moves towards the side where the driving motor 11 is located. The connecting rod 19 acts under the drive of the lead screw nut 20. The locking hook 9 is pulled by the connecting rod 19 to rotate and separate from the locking buckle 10. The torsion spring 21 of the electric control door opening and closing actuator provides elastic force to assist the rotation of the locking hook 9. At the same time, the sliding sleeve 23 also slides relative to the lead screw 15. At this time, since the limiting part 25 does not contact the sliding ring 24, the sliding ring 24 remains stationary under the action of the elastic buffer 13. Correspondingly, the support rod 16 does not act either, and the cabinet door 2 remains stationary. After the unlocking mechanism 18 completes unlocking, the driving motor 11 continues to drive the lead screw 15 to rotate. The lead screw nut 20 drives the sliding ring 24 to move to the left through the limiting part 25 on the right side, and the elastic buffer 13 is compressed. Driven by the sliding ring 24, the relative position of the connection point of the support rod 16 and the sliding ring 24 with respect to the cabinet door 2 will change, so that the cabinet door 2 can be opened, automatically completing the actions of unlocking first and then opening the door. The structure is reasonable and effective.

[0095] 2) Door closing action: The driving motor 11 drives the lead screw 15 to rotate in the reverse direction. The sliding sleeve 23 and the lead screw nut 20 move to the right under the action of the lead screw 15. The elastic buffer 13 in the compressed state provides elastic force to drive the sliding ring 24 to also move to the right. The support rod 16 pulls the cabinet door 2 towards the cabinet body, that is, closes the cabinet door 2. Then the driving motor 11 continues to drive the lead screw 15 to rotate. The connecting rod 19 continues to act under the drive of the lead screw nut 20. The locking hook 9 is pushed by the connecting rod 19 to rotate in the reverse direction and connect with the locking buckle 10, automatically completing the actions of closing the door first and then locking.

[0096] The above are only optional embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
