[0039] The present invention provides a storage device 100 .

[0040] Reference Figures 1 to 7As shown, in one embodiment of the present invention, the storage device 100 includes: an outer shell 20, a driving mechanism 40 and a placement mechanism 30, the outer shell 20 includes a cabinet body 21 and a door body 22, the cabinet body 21 is provided with a cavity 211 and an opening connected to the cavity 211, the door body 22 is rotatably connected to the cabinet body 21 to open or cover the opening, a support assembly 10 is provided on the side of the door body 22 facing the opening, the driving mechanism 40 is provided in the cavity 211, the placement mechanism 30 is movably provided in the cavity 211 and is connected to the driving mechanism 40, wherein the driving mechanism 40 can drive the placement mechanism 30 to push the door body 22 to rotate relative to the cabinet body 21, so that the placement mechanism 30 is supported on the support assembly 10 and slides along the support assembly 10.

[0041] The storage device 100 of the present invention is provided with support assemblies 10 on the inner surfaces of the two door bodies 22, so that when the storage mechanism 30 extends out of the cabinet body 21, the front end of the storage mechanism 30 can be supported by the two support assemblies 10. The storage device 100 drives the storage mechanism 30 through the driving mechanism 40, so that the storage mechanism 30 moves forward and gradually extends out of the cabinet body 21. At this time, the two door bodies 22 rotate under the drive of the storage mechanism 30 and are in an open state. As the driving mechanism 40 continues to drive, the two ends of the storage mechanism 30 contact the two support assemblies 10 respectively and slide on the two support assemblies 10, so that the two support assemblies 10 both support the storage mechanism 30. In this way, the storage mechanism 30 can still be supported by the support assemblies 10 on the door body 22 after extending out of the cabinet body 21, effectively improving the load capacity of the storage mechanism 30 and the stability of the overall movement process.

[0042] It can be understood that the storage mechanism 30 is used to place and store items. The driving mechanism 40 can be a cylinder. The driving mechanism 40 can also be a driving structure of a motor 41 and a ball screw, a structure of a motor 41 and a gear 42 and a rack 43, etc. As long as it is a structure that can realize the movement of the storage mechanism 30 relative to the cabinet 21, it is not limited here.

[0043] Reference Figures 3 to 4 As shown, in one embodiment, the support assembly 10 includes a first slide rail 11 and a first rotating assembly 12. The first slide rail 11 is arranged on the side of the door body 22 facing the opening. The first slide rail 11 cooperates with the door body 22 to form a support step. The first rotating assembly 12 is rotatably arranged on the support step, wherein the placement mechanism 30 is slidably supported on the support step and rollingly abuts against the first rotating assembly 12.

[0044] As can be understood, the storage mechanism 30 moves horizontally, while the door body 22 rotates vertically. In this embodiment, the first slide rail 11 extends along the direction of movement of the storage mechanism 30. The first slide rail 11 is connected to the door body 22, formed and protruding on the surface of the door body 22, so that the first slide rail 11 cooperates with the surface of the door body 22 to form a support step for supporting the storage mechanism 30. As the storage mechanism 30 continues to move outward, the first rotating assembly 12 rolls against the storage mechanism 30. This rolling friction reduces the friction experienced by the storage mechanism 30 during movement, which helps improve the smoothness of the movement of the storage mechanism 30.

[0045] It is understandable that the first slide rail 11 may be integrally formed with the door body 22 , may be detachably assembled on the door body 22 by screwing, or may be fixed to the door body 22 by welding.

[0046] Optionally, two or more first slide rails 11 may be provided, and the two or more first slide rails 11 are spaced apart in the vertical direction. Such arrangement can reduce the force exerted on a single first slide rail 11 , thereby increasing the service life of the first slide rail 11 .

[0047] It is understood that the cross-section of the first slide rail 11 can be square, trapezoidal, or arc-shaped. The first slide rail 11 with a trapezoidal or arc-shaped cross-section has a limiting function, which can limit the horizontal movement of the door body 22. This prevents the door body 22 from further rotating due to external force, resulting in the placement mechanism 30 being unable to reset.

[0048] Reference Figure 1 、 Figure 6 and Figure 7 As shown, in one embodiment, the storage mechanism 30 defines a first sliding groove 311 that slides with the first slide rail 11 and rolls against the first rotating assembly 12. The first sliding groove 311 extends along the moving direction of the storage mechanism 30.

[0049] It can be understood that the shape of the first slide groove 311 is adapted to the outer shape of the first slide rail 11. When the placement mechanism 30 slides with the first slide rail 11, the first slide groove 311 covers the first slide rail 11. The upper surface of the first slide rail 11 abuts against the upper wall of the first slide groove 311, so that the placement mechanism 30 is supported on the first slide rail 11. When the placement mechanism 30 cooperates with the first rotating component 12, the first rotating component 12 rolls and abuts against the upper wall of the first slide groove 311. In this embodiment, the number of first slide grooves 311 is equal to the number of first slide rails 11. This structure is simple and does not require more complicated processing of the first slide rail 11.

[0050] In an embodiment, the storage mechanism 30 is provided with a protrusion extending along the sliding direction of the storage mechanism 30, the support step is provided with a second sliding groove, the protrusion is in sliding connection with the second sliding groove, and the protrusion is in rolling abutment with the first rotating assembly 12. The second sliding groove extends along the horizontal direction, and the shape of the second sliding groove is matched with the shape of the protrusion. When the storage mechanism 30 is in sliding connection with the first sliding rail 11, the protrusion is inserted into the second sliding groove and slides along the second sliding groove. The first rotating assembly 12 is in rolling abutment with the bottom surface of the protrusion. It can be understood that the number of the protrusions is equal to the number of the second sliding grooves.

[0051] Referring to Figure 4 In an embodiment, one end of the first sliding rail 11 is provided with a guide structure 111 adjacent to the end of the door body 22 and the cabinet body 21 connected in a rotating manner. The guide structure 111 is used to guide the storage mechanism 30. In this embodiment, the guide structure 111 is an inverted bevel or an inverted round corner. In this way, the first sliding rail 11 can be more smoothly inserted into the first sliding groove 311, thereby improving the smoothness when the drawer 31 moves outward.

[0052] It can be understood that the end of the first sliding groove 311 close to the door body 22 is provided with a chamfer to form a flared portion. In this way, the first sliding rail 11 can be more smoothly inserted into the first sliding groove 311.

[0053] Referring to Figure 4 In an embodiment, the first rotating assembly 12 includes a plurality of first rotating members 121 rotatably arranged on the support step and in rolling abutment with the storage mechanism. It can be understood that the first rotating members 121 can be rollers or balls. In this embodiment, the first rotating members 121 are rollers, which are rotatably connected to the first sliding rail 11 by a rotating shaft, and each roller rotates around a horizontal axis. The plurality of rollers are arranged at intervals along the extension direction of the first sliding rail 11. In this way, the rolling friction is used to reduce the frictional force when the storage mechanism 30 moves, which is beneficial to improve the smoothness when the storage mechanism 30 moves.

[0054] Referring to Figures 1 to 3 In an embodiment, two door bodies 22 are provided, which are symmetrically arranged and rotatably connected to the cabinet body 21 to cooperate with opening or closing the opening. The two door bodies 22 constitute a double-door structure, the rotating directions of the two door bodies 22 are opposite, and the two door bodies 22 are rotatably connected to the left and right ends of the cabinet body 21, respectively. The first sliding rail 11 is arranged on each of the two door bodies 22, and the first sliding groove 311 is arranged on the left and right end faces of the cabinet body 21. In this way, when the storage mechanism 30 moves outward and extends out of the cabinet body 21, the two ends of the storage mechanism 30 can be supported on the two first sliding rails 11, respectively, which greatly improves the stability and the load capacity of the storage mechanism 30.

[0055] Referring to Figures 1 to 3 and Figure 5 As shown, in one embodiment, the storage device 100 further includes a stop mechanism 50, which is provided on the cabinet body 21 and is used to lock and release the door body 22. It is understandable that the stop mechanism 50 can be a structure in which a lock tongue and a lock hole cooperate, can be a magnetic module adsorption structure, or can be a combination of a magnetic module and a lock tongue and lock hole structure. As long as the structure can achieve locking and releasing the door body 22, it is not limited here. The stop mechanism 50 is provided so that when the storage mechanism 30 is stored in the cabinet body 21, the door body 22 is locked, thereby preventing the door body 22 from rotating and reducing vibration. At the same time, it can also prevent the items in the storage mechanism 30 from being stolen.

[0056] Reference Figures 1 to 3 and Figure 5 As shown, in one embodiment, the stop mechanism 50 includes a fixed seat 53, an electromagnetic assembly 52, and a stop assembly 51. The fixed seat 53 is disposed in the cavity 211. The electromagnetic assembly 52 and the stop assembly 51 are both disposed on the fixed seat 53. A stop member 23 is provided on the side of the door body 22 facing the opening. The electromagnetic assembly 52 and the stop assembly 51 cooperate so that the stop assembly 51 abuts against the stop member 23. In this embodiment, the fixed seat 53 is fixedly connected to the upper wall surface of the cabinet body 21. The fixed seat 53 is disposed adjacent to the opening and the center line of the cabinet body 21. The stop assembly 51 and the electromagnetic assembly 52 are both connected to the surface of the fixed seat 53 facing the center of the cabinet body 21. Since two door bodies 22 are provided, two stop members 23 are also provided. Two stoppers 23 are fixedly connected to the upper ends of the two door bodies 22, respectively. The stoppers 23 are located away from the corresponding ends of the door bodies 22 and the cabinet body 21, so that the stopper assembly 51 can simultaneously abut and limit the two stoppers 23 while reducing the size of the stopper assembly 51. The electromagnetic assembly 52 is provided to attract the stopper assembly 51 to achieve automatic locking of the door bodies 22, greatly improving practicality and convenience.

[0057] In one embodiment, the electromagnetic component 52 can generate a repulsive force and push the stop component 51, causing the stop component 51 to move upward, thereby releasing the two door bodies 22. When the two door bodies 22 are closed, the electromagnetic component 52 is powered off, and the stop component 51 can move downward by its own gravity and limit the position against the limit member 23.

[0058] As will be appreciated, the electromagnetic assembly 52 can generate both attractive and repulsive forces by changing the direction of the current. The electromagnetic assembly 52 uses the attractive force to attract the stopper assembly 51, forcing it to abut against the stopper 23, thereby locking the door 22. The electromagnetic assembly 52 uses the repulsive force to push the stopper assembly 51 away from the stopper 23, thereby releasing the door 22.

[0059] Reference Figure 5As shown, in one embodiment, two electromagnetic assemblies 52 and two stop assemblies 51 are each provided, and the two electromagnetic assemblies 52 correspond to the two stop assemblies 51, and the two stop assemblies 51 correspond to the two stop members 23. The stop assembly 51 includes a moving member 512, a first elastic member 513, and a first connecting rod 511. The first connecting rod 511 is movably connected to the fixed base 53, and the upper end of the moving member 512 is connected to one end of the first connecting rod 511. The moving member 512 is slidably provided with the corresponding electromagnetic assembly 52, and the first elastic member 513 is a spring. One end of the first elastic member 513 is elastically connected to the corresponding electromagnetic assembly 52, and the other end is elastically connected to the upper end of the corresponding moving member 512. When the two door bodies 22 are closed, the electromagnetic assembly 52 is energized to attract the first connecting rod 511, which drives the moving member 512 to move downward and limit against the stop member 23, at which time the first elastic member 513 is compressed. When the door body 22 needs to be released, the electromagnetic assembly 52 is powered off, and the moving member 512 moves upward under the action of the first elastic member 513 to reset.

[0060] It is understood that in one embodiment, when the electromagnetic assembly 52 is energized, a repulsive force is generated to push the first connecting rod 511 away. The first connecting rod 511 drives the movable member 512 upward, causing the movable member 512 to disengage from the stopper 23, thereby releasing the door body 22. At this time, the first elastic member 513 is stretched. When the electromagnetic assembly 52 is de-energized, the movable member 512 moves downward under the action of the first elastic member 513 to reset.

[0061] In one embodiment, the limiting member 23 is provided with a limiting hole for the movable member 512 to be inserted, and the limiting hole is arranged along the height direction. The movable member 512 limits the movement of the limiting member 23 by being inserted into the limiting hole, thereby limiting the movement of the door body 22. It can be understood that the limiting hole can be a through hole or a blind hole, and the shape of the limiting hole can be circular, irregular, square or polygonal, as long as it is compatible with the shape of the movable member 512, and is not limited here. In this embodiment, the limiting hole is a through hole, and its shape is circular, and the lower end of the movable member 512 is provided with chamfers or fillets to allow the movable member 512 to be inserted into the limiting hole more smoothly. Setting the limiting hole as a through hole can reduce the noise generated when a collision occurs between the movable member 512 and the limiting hole.

[0062] Reference Figure 5As shown, in one embodiment, the locking mechanism 50 further includes a forced unlocking assembly 54, which is disposed on the fixed seat 53 and is interlocked with the locking assembly 51. In this embodiment, the forced unlocking assembly 54 includes a push rod 541 and a second elastic member 542, wherein the second elastic member 542 is a spring. The push rod 541 is slidably disposed through the fixed seat 53. Two electromagnetic assemblies 52 are symmetrically disposed on the left and right ends of the push rod 541, and two locking assemblies 51 are symmetrically disposed on the left and right ends of the push rod 541. Both electromagnetic assemblies 52 are rotatably connected to the fixed seat 53. One end of each of the two first connecting rods 511 is hingedly connected to the corresponding movable member 512, and the other end is hingedly connected to the lower end of the push rod 541 via a hinge shaft. The upper end of the push rod 541 is slidably disposed through the cabinet body 21. The middle portion of each of the two first connecting rods 511 is hingedly connected to the fixed seat 53. The hinged connection between the two first connecting rods 511 and the push rod 541 is provided with a strip hole, and the hinge shaft can slide through the strip hole. The two ends of the second elastic member 542 are elastically connected to the fixing seat 53 and the hinge shaft respectively, and the second elastic member 542 is arranged along the height direction.

[0063] When the door 22 needs to be opened, the electromagnetic assembly 52 is energized and generates a repulsive force to push the corresponding first connecting rod 511 open. The first connecting rod 511 drives the corresponding moving member 512 to move upward, so that the moving member 512 is disengaged from the limiting hole, thereby achieving the purpose of releasing the door 22. When the door 22 is opened, the electromagnetic assembly 52 is powered off, so that the moving member 512 is reset under the action of the first elastic member 513, which greatly saves energy. When the two door bodies 22 gradually close, the electromagnetic assembly 52 is energized, so that the moving member 512 moves upward. When the two door bodies 22 are completely closed, the electromagnetic assembly 52 is powered off, so that the moving member 512 is reset and inserted into the corresponding limiting hole. When the power supply is out of power or the circuit of the electromagnetic assembly 52 fails, the push rod 541 can be manually pressed. The push rod 541 moves downward to stretch the second elastic member 542 and drive the two first connecting rods 511 to rotate, thereby driving the two moving members 512 to move upward and disengage from the two limiting holes. After the push rod 541 loses its external force, it returns to its original position under the action of the second elastic member 542, driving the two first connecting rods 511 to rotate in opposite directions. The movable member 512, driven by the corresponding first connecting rod 511, then moves downward and inserts into the corresponding stop hole. This allows the storage device 100 of the present invention to be manually unlocked and locked even in the event of a power outage or a circuit failure in the electromagnetic assembly 52, significantly improving its practicality and flexibility.

[0064] In one embodiment, the locking mechanism 50 includes a mounting base 53, an electromagnetic assembly 52, and an adsorbent. The mounting base 53 is mounted on the cabinet 21, and the electromagnetic assembly 52 is mounted on the mounting base 53. Two adsorbents are provided, each connected to the surface of the two doors 22 facing the center of the cabinet 21. When the two doors 22 are closed, the electromagnetic assembly 52 is energized and attracts the two adsorbents. In this embodiment, each adsorbent can be secured to the door 22 by welding or screwing. By using the electromagnetic assembly 52 to directly attract the adsorbents, the use of mechanical structures and parts can be reduced, thereby reducing production costs.

[0065] It is understandable that the door body 22 can be made of a magnetic metal. In this way, there is no need to use an adsorption component. The electromagnetic component 52 can directly adsorb the door body 22 after being energized, further reducing the difficulty of assembly.

[0066] Reference Figures 2 to 3 As shown, in one embodiment, the housing 20 further includes a linear guide assembly 24, which includes a second slide rail and a second slider slidably connected to the second slide rail. The second slide rail is disposed within the cavity 211 and extends along the direction of movement of the storage mechanism 30, which is disposed on the second slider. In this embodiment, two linear guide assemblies 24 are provided. Both second slide rails are removably connected to the bottom wall of the cabinet 21 and are located on the left and right ends of the drive mechanism 40, respectively. Both second sliders are removably connected to the bottom of the storage mechanism 30 and are located on the left and right ends of the storage mechanism 30, respectively. The linear guide assembly 24 utilizes rolling friction, which helps reduce the coefficient of friction and improves the smoothness of the movement of the storage mechanism 30. Furthermore, it serves as a guide for the storage mechanism 30. Providing two linear guide assemblies 24 reduces the force applied to a single linear guide assembly 24, thereby increasing the service life of the linear guide assemblies 24 and ensuring uniform force distribution within the storage mechanism 30.

[0067] Reference Figures 2 to 4 As shown, in one embodiment, one end of the door body 22 is rotatably connected to the cabinet body 21 via a rotating shaft 25, and an elastic reset member 26 is sleeved on the rotating shaft 25. The two ends of the elastic reset member 26 are elastically connected to the cabinet body 21 and the door body 22 respectively. In this embodiment, one end of each of the two door bodies 22 is rotatably connected to the cabinet body 21 via a rotating shaft 25, and the elastic reset member 26 is a coil spring. The storage mechanism 30 pushes the two door bodies 22 apart through thrust and causes the two door bodies 22 to rotate relative to the cabinet body 21. The coil spring is provided so that when the storage mechanism 30 is reset, the two door bodies 22 can be reset under the action of their respective elastic reset members 26 without the need to manually close the door, which greatly improves practicality.

[0068] Reference Figure 4 、 Figure 6 and Figure 7As shown, in one embodiment, the storage mechanism 30 includes a drawer 31 and an active member 32. A receiving cavity for placing items is provided at the top of the drawer 31. Two active members 32 are provided. The two active members 32 are fixedly connected to the bottom of the drawer 31 and are respectively located at the left and right ends of the drawer 31. The ends of the two active members 32 close to the opening are provided with an inclined surface 321. The inclined surface 321 gradually tilts toward the center of the opening from away from the opening to close to the opening. The second rotating member 27 is rotatably connected to the surface of the two door bodies 22 facing the opening. The second rotating member 27 is adjacent to the corresponding door body 22 and the end of the cabinet body 21 where it is rotatably connected. The driving mechanism 40 drives the drawer 31 and drives the two active members 32. The two active members 32 push the two second rotating members 27 respectively through the inclined surfaces 321 thereon, thereby driving the two door bodies 22 to rotate. This linkage method is simple and helps to reduce the difficulty of processing and assembly.

[0069] It is understood that the second rotating member 27 can be a roller or a ball bearing. In this embodiment, the second rotating member 27 is a roller, which is rotatably connected to the corresponding door body 22 via a rotating shaft, and each roller rotates about a vertical axis. This arrangement helps improve the smoothness of the linkage between the active member 32 and the door body 22.

[0070] It can be understood that there is a predetermined distance between the first slide rail 11 and the corresponding rotating shaft 25. This arrangement allows the storage mechanism 30 to slide and cooperate with the first slide rail 11 only after the storage mechanism 30 fully opens the two door bodies 22. This design adopts intermittent linkage, so that the storage mechanism 30 only needs to move a short distance to fully open the two door bodies 22, without having to wait until the storage mechanism 30 moves to the extreme end of the stroke for the two door bodies 22 to be fully opened. In this way, users can take and put items in advance. It greatly improves the efficiency of taking and putting items, and at the same time does not wear out the user's patience, that is, the user does not need to watch the two door bodies 22 gradually open throughout the process, ensuring the user's needs.

[0071] In one embodiment, the drive mechanism 40 utilizes a pneumatic cylinder. Cylinders are conventional technology and will not be described in detail here. The cylinder is mounted within the cabinet 21 and is located on the bottom wall of the cavity 211. The telescopic end of the cylinder is positioned toward the opening. A push-pull plate is provided at the bottom end of the drawer 31 near the opening. The cylinder is positioned below the drawer 31, and the telescopic end of the cylinder is connected to the push-pull plate. This arrangement effectively utilizes space and reduces the size of the cabinet 21. The cylinder has a simple structure and is easy to maintain, which helps reduce assembly difficulty.

[0072] Optionally, the drive mechanism 40 utilizes an electric push rod, which is conventional technology and will not be described in detail here. The push rod is mounted within the cabinet 21 and located on the bottom wall of the cavity 211. The telescopic end of the push rod is positioned toward the opening. A push plate is provided at the bottom of the drawer 31, near the opening. The push rod is located below the drawer 31, and the telescopic end of the push rod is connected to the push plate.

[0073] Reference Figure 7 As shown, in one embodiment, the driving mechanism 40 includes a motor 41, a gear 42 and a rack 43. The motor 41 is installed in the cabinet 21 and is located on the bottom wall of the cavity 211. The motor 41 is linked to the gear 42. The rack 43 extends along the moving direction of the drawer 31 and is installed at the bottom of the drawer 31. The rack 43 is engaged with the gear 42. The motor 41 drives the drawer 31 to adjust the moving distance of the drawer 31. On the one hand, it can prevent the drawer 31 from moving too long, causing the drawer 31 to press against the door body 22, thereby causing damage to the door body 22, the rotating shaft 25, and the cabinet 21; on the other hand, it can prevent the drawer 31 from moving too short, causing the user to reach into the cabinet 21 to pick up items. The method of using the motor 41 to drive the gear 42 and the rack 43 can drive the drawer 31 to a suitable position to meet the user's experience.

[0074] The present invention also provides a delivery robot comprising the aforementioned storage device 100. The storage device 100 of this technical solution comprises support assemblies 10 disposed on the inner surfaces of the two doors 22, thereby enabling the front end of the storage mechanism 30 to be supported by the two support assemblies 10 when the storage mechanism 30 extends outside the cabinet 21. This ensures that the storage mechanism 30 remains supported by the support assemblies 10 on the doors 22 even after extending outside the cabinet 21, effectively improving the load capacity of the storage mechanism 30 and the stability of the overall movement process, greatly enhancing the practicality of the delivery robot.
