[0055] In order to make the purpose, technical scheme and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0056] In some embodiments, Figure 1 and Figure 2 The storage device 100 shown in the figure comprises a cabinet 1. The cabinet 1 has Figure 5 and Figure 6 The storage device 100 here can be a cabinet with storage function such as a courier cabinet, a cargo container, a wardrobe, etc. The traditional structure of the above cabinet is usually fixed in its internal storage space, which may cause space waste for some small objects that need to be stored separately. Therefore, in order to make reasonable use of the space of the inner cavity 1C, the present application has made some relevant improvements to the traditional cabinet, which are described in detail below:

[0057] like Figure 1 and Figure 2 As shown, the mouth of the inner cavity 1C is located at the front end face of the cabinet 1; it is assumed that the space has a three-coordinate system consisting of an X-axis, a Y-axis and a Z-axis that are orthogonal to each other, that is, a three-coordinate system constructed by virtual X-axis, Y-axis and Z-axis along the width, depth and height directions of the cabinet 1, and the width direction of the cabinet 1 is assumed to be the X-axis, the depth direction is the Y-axis, and the height direction is the Z-axis.

[0058] The height direction of the inner cavity 1C is arranged along the Z axis, the depth direction of the inner cavity 1C is arranged along the Y axis, and the width direction of the inner cavity 1C is arranged along the X axis.

[0059] like Figure 2 and Fig.16 As shown, the storage device 100 further includes a first partition 6 and a second partition 7. The first partition 6 is movably connected to the inner cavity 1C, and divides the inner cavity 1C into a plurality of first storage cavities 1C1 arranged along the X-axis direction through a first adjustment movement, and divides adjacent first storage cavities 1C1 into a plurality of first storage cavities 1C1 arranged along the X-axis direction through a first adjustment movement. Fig.18 The second partition 7 is movably connected to the first storage cavity 1C1, and the first storage cavity 1C1 is divided into a plurality of second storage cells arranged along the Y-axis direction by a second adjustment movement, and the adjacent second storage cells are merged by a second adjustment movement. In this way, the inner cavity 1C can be adjusted in space in the X-axis direction by merging / separating adjacent first storage cavities 1C1, and the first storage cavity 1C1 can be adjusted in space in the Y-axis direction by merging / separating adjacent second storage cells, thereby achieving free adjustment of the internal space of the entire cabinet 1, that is, ensuring maximum space utilization.

[0060] The first adjustment movement and the second adjustment movement here are both preset movement rules, which are used to define the movement trajectory and movement mode of the first partition 6 and the second partition 7. The different active connection modes of the first partition 6 and the second partition 7 with the inner cavity 1C also determine the specific types of the first adjustment movement and the second adjustment movement. The following is an example:

[0061] For example, the first partition 6 and the second partition 7 are movably connected to the top of the inner cavity 1C in a manner similar to a rolling door structure. The first partition 6 and the second partition 7 can be gradually unfolded and drooped from the top of the inner cavity 1C like a rolling door, or gradually rolled back and stored at the top of the inner cavity 1C from the bottom of the inner cavity 1C, so as to realize the division of the inner cavity 1C into a plurality of first storage chambers 1C1, and the division of the first storage chamber 1C1 into a plurality of second storage compartments. Then the first adjustment movement and the second adjustment movement are both the mutual switching between the unfolding and drooping / rolling and storing states of a rolling door.

[0062] For another example, the movable connection between the first partition 6, the second partition 7 and the inner cavity 1C adopts a sliding fit, so that the movement paths of the first partition 6 and the second partition 7 are constrained. Specifically, the first adjustment movement is to make the first partition 6 slide along the X-axis in the inner cavity 1, and the second adjustment movement is to make the second partition 7 slide along the Y-axis in the inner cavity 1C. The position change is achieved through the translation and sliding of the two, so that the storage space in the inner cavity 1C is adjustable. Of course, it is also possible to adopt a combination of setting the first adjustment movement as a translation and sliding, and the second adjustment movement as a rotational movement, or setting the first adjustment movement as a rotational movement, and the second adjustment movement as a translation and sliding combination to achieve space adjustment, etc. Any movement method to achieve the adjustment of the storage space of the inner cavity 1C is not described in detail here. As a further preferred structure, multiple first partitions 6 can be set along the X-axis direction, so that the inner cavity 1C can be divided into more first storage cavities 1C1 along the X-axis direction to better meet the needs of storing items.

[0063] In some embodiments, the movable connection between the first partition 6, the second partition 7 and the inner cavity 1C is preferably in the form of a hinge, and the first adjustment movement and the second adjustment movement are preferably rotational movements, which are described in detail below:

[0064] like Figure 2 , Figure 4 and Fig.10 As shown, the second partition 7 includes a second partition body 7A and a hanging portion 7B arranged on the top of the second partition body 7A; the hanging portion 7B can be hinged to the inner cavity 1C by means of a hinge or a hanging rod 8 at the top of the inner cavity 1C. A switching mechanism corresponding to the position of the second partition 7 is installed on the cabinet 1; the switching structure here is a structure that can rotate the second partition 7, that is, a second adjustment movement, for example, the switching mechanism can be a motor axially connected to the hanging portion 7B along the X-axis direction, and the second partition 7 is driven by the rotation of the motor to perform a second adjustment movement specifically rotation; the switching structure can also be a cylinder assembly, by connecting the switching mechanism of the cylinder assembly structure to the second partition 7 and forming a crank slider mechanism, so that the reciprocating movement of the piston rod in the cylinder assembly is converted into the rotational movement of the second partition 7; this application is preferably Figure 2 The limiting device 4 and the resetting device 5 are combined as shown, and the specific structures and movement modes of the limiting device 4 and the resetting device 5 will be described in detail later.

[0065] The second adjustment movement is a rotational movement of the rotation plane perpendicular to the X-axis, and can enable the second partition 7 to have a second unfolded state and a second retracted state that can be switched between each other. Fig.14 and Fig.15 As shown, the second partition body 7A is in a vertical position perpendicular to the Y axis, and the two adjacent second storage cells are separated; the second retracted state is as shown in FIG. Fig.16 and Fig.17As shown, the second partition body 7A is in a horizontal position perpendicular to the Z axis and located at the top of the inner cavity 1C, and two adjacent second storage cells are merged.

[0066] like Figure 2 , Fig.16 and Fig.17 As shown, the top of the first partition 6 is hinged to the top of the inner cavity 1C. The first adjustment movement is a rotation movement of the rotation plane perpendicular to the Y axis, and the first partition 6 has a first expanded state and a first retracted state. Fig.16 and Fig.17 As shown, the first partition 6 is in a vertical position perpendicular to the X axis, and the two adjacent first storage chambers 1C1 are separated. Fig.18 and Fig.19 As shown, the first partition 6 is located at a horizontal position perpendicular to the Z axis and at the top of the inner cavity 1C, and two adjacent first storage cavities 1C1 are merged.

[0067] In some embodiments, Figure 7 As shown, the first partition 6 includes a first partition body 6A and a first sealing plate 6B formed by extending the front end of the first partition body 6A in the lateral direction. The first partition body 6A and the first partition body 6A are perpendicular to each other. Figure 6 The cabinet 1 shown in the figure also includes a cantilever beam body 1E arranged on the top surface of the inner cavity 1C. The cantilever beam body 1E includes a cantilever beam ridge 1E2; the cantilever beam ridge 1E2 is a convex strip formed by extending along the Z axis to the bottom of the inner cavity 1C along the length direction of the Y axis. Figure 2 and Figure 3 As shown, it is hinged to the bottom of the cantilever beam 1E. Fig.18 and Fig.19 As shown, when the first partition 6 is in the first retracted state, it will be attached to the top surface of the inner cavity 1C through the first sealing plate 6B, and a gap cavity is formed between the side plate surface of the first partition body 6A and the top surface of the inner cavity 1C. In this way, when the first partition 6 is in the first storage state, and the corresponding second partition 7 is also in the second storage state at the same time, the gap cavity formed by the first partition 6 can re-store the second partition 7 at this time, ensuring that the two cooperate with each other to achieve the top surface of the inner cavity 1C without interfering with each other, and reasonably utilizing the space.

[0068] More preferably, Figure 7As shown, the side edge of the first sealing plate 6B has a first support plate 6C extending in a direction parallel to the first partition body 6A, and a third lock 6D is provided on the side of the first support plate 6C. The third lock 6D is preferably a magnetic buckle, and the cabinet body 1 is preferably made of a magnetic metal material. When the first partition 6 is in the first retracted state, it can be magnetically fixed to the top surface of the inner cavity 1C through the adsorption effect of the third lock 6D. At the same time, in order to achieve a better magnetic effect, the first sealing plate 6B, the first support plate 6C and the third lock 6D should be symmetrically arranged at both ends of the first partition body 6A. When the first partition 6 is in the first retracted state, both ends of the first partition 6 can be adsorbed on the top surface of the inner cavity 1C to form a more stable fixing effect.

[0069] In some embodiments, the storage device 100 further includes Figure 2 and Figure 4 The hanging rod 8 shown. Figure 6 As shown, the two opposite side walls of the cabinet 1 and the suspension beam ridge 1E2 are provided with through hanging holes 1F arranged along the X-axis direction. The hanging rod 8 is sequentially arranged along the X-axis direction through the hanging holes 1F of one side wall of the cabinet 1, the suspension beam ridge 1E2 and the other side wall of the cabinet 1, and the two ends of the hanging rod 8 are fixedly connected to the hanging holes 1F of the two opposite side walls of the cabinet 1, and the middle section of the hanging rod 8 is suspended on the top of the inner cavity 1C. The hanging portion 7B is sleeved and rotatably connected to the hanging rod 8.

[0070] The switching mechanism preferably includes a limiting device 4 and a resetting device 5, both of which are arranged on the side of the second partition 7. The limiting device 4 can be any mechanism used to limit the second partition 7 so that the second partition 7 maintains the second expanded state; and the resetting device 5 can be any mechanism that can drive the second partition 7 to switch from the second expanded state to the second stored state after the limiting device 4 releases the limiting of the second partition 7. For example, the resetting device 5 is a torsion spring or a coil spring structure. When the second partition 7 is in the second expanded state, the resetting device 5 stores angular energy through torsional deformation. When the limiting device 4 releases the limiting of the second partition 7, the resetting device 5 will gradually restore the torsional deformation and release the angular energy, thereby driving the second partition 7 to switch to the second stored state. At the same time, based on the determination of the torsion spring or coil spring structure of the resetting device 5, the limiting device 4 can be set as follows Fig. 20A As shown in the electric control lock buckle located at the bottom surface of the inner cavity 1C, when the second partition 7 is in the second unfolded state, the electromagnetic lock buckle is spring-loaded to lock the second partition 7. When the electric control lock buckle is started, the electromagnet at the bottom of the electromagnetic lock buckle generates a downward adsorption force, so that the electromagnetic lock buckle is pressed downward as a whole, thereby releasing the limit, and then the reset device 5 resets the second partition 7 to the second storage state; for example, the limit device 4 is set to Fig. 20BThe wedge-shaped block shown on the bottom surface of the inner cavity 1C, when the second partition 7 is in the second expanded state, the spring bounces up to form a limit block on the back of the wedge-shaped block for the second partition 7, and when the second partition 7 is pressed, the blockage can be released and the second partition 7 can be reset to the second storage state through the reset device 5; of course, the limit device 4 can also be any other mechanism to achieve the above functions. The following describes a preferred structure and use method of the limit device 4 and the reset device 5 of the present application:

[0071] like Figure 5 As shown, the top wall of the cabinet 1 is provided with a through hole 1A corresponding to the position of the second partition 7. The second partition 7 also includes Fig.10 The second locking plate body 7C is shown in FIG. The second partition body 7A and the second locking plate body 7C are respectively arranged on the outer periphery of the hanging portion 7B. The second locking plate body 7C is shown in FIG. Fig.15 and Fig. 20 As shown, it is received in through hole 1A.

[0072] like Figure 2 and Fig.15 As shown, the position of the limiting device 4 corresponds to the first partition 6 and is arranged on the top surface of the cabinet 1. The limiting device 4 includes Fig.12 and Fig.13 The electromagnetic lock body 4A, the electromagnet 4D disposed in the electromagnetic lock body 4A, the return spring 4C and the wedge 4B whose tail is inserted in the electromagnetic lock body 4A. The two ends of the return spring 4C are respectively connected to the top of the electromagnet 4D and the tail of the wedge 4B; the wedge 4B is located directly above the through hole 1A. When the limit device 4 is started, the electromagnet 4D retracts the wedge 4B into the electromagnetic lock body 4A; when the limit device 4 is closed, the return spring 4C drives the head of the wedge 4B to extend out of the electromagnetic lock body 4A.

[0073] The reset device 5 is Fig.11 The torsion spring structure shown in FIG. 5 includes a torsion spring body 5B and a first torsion arm 5A and a second torsion arm 5C respectively disposed at both ends of the torsion spring body 5B. Figure 4 and Fig.15 As shown, it is sleeved on the hanging rod 8 and is always in a torsion deformation state, and the first torsion arm 5A is in contact with the back of the second partition 7, and the second torsion arm 5C is in contact with the top surface of the inner cavity 1C; contact means that multiple objects are squeezed and stressed against each other and keep in contact with each other. The following describes the use principle of the limit device 4 and the reset device 5:

[0074] like Fig.14 and Fig.15As shown, when the second partition 7 is in the second expanded state, the torsional deformation of the torsion spring body 5B will cause the second partition 7 to have a tendency to rotate clockwise, and at this time, the bottom surface of the wedge block 4B will prevent the second partition 7 from rotating clockwise by abutting against the top edge of the second lock plate body 7C. At the same time, when the second partition 7 tends to rotate counterclockwise due to external force, the torsional deformation of the torsion spring body 5B will prevent the second partition 7 from rotating counterclockwise, thereby keeping the second partition 7 fixed in the second expanded state.

[0075] like Fig.16 and Fig.17 As shown, when the limit device 4 is activated, the electromagnet 4D generates a magnetic attraction force to retract the wedge block 4B into the electromagnetic lock body 4A, thereby releasing the contact between the bottom surface of the wedge block 4B and the top edge of the second lock plate body 7C. At this time, the torsion spring body 5B gradually recovers the torsion deformation and releases the angular energy to drive the second partition plate 7 to start rotating clockwise, thereby switching from the second unfolded state to the second retracted state. Since the torsion spring body 5B always maintains the torsion deformation, it will keep the second partition plate 7 fixed in the second retracted state when no external force is applied.

[0076] When the second partition 7 needs to be switched from the second storage state to the second expansion state, an external force is applied to the second partition 7 to rotate it counterclockwise, such as manually pulling the second partition 7 to rotate. Fig. 20 As shown in the figure, the second lock plate body 7C will cause its top edge to hit the head end face of the wedge block 4B due to the rotational movement, and generate a horizontal component force to make the wedge block 4B start to be retracted into the electromagnetic lock body 4A. When the second lock plate body 7C moves as a whole to the bottom of the wedge block 4B and completely enters the through hole 1A, the wedge block 4B is pushed out again by the return spring 4C, and the second partition plate 7 returns to the Fig.15 The second deployed state is shown. It should be pointed out here that in order to enable the second lock plate body 7C to generate a larger horizontal component force when hitting the wedge block 4B, the angle between the second partition body 7A and the second lock plate body 7C is an obtuse angle of 110° to 160°, and preferably 135°, and the opening faces the cavity opening of the inner cavity 1C, while the head end face of the wedge block 4B is an inclined surface, and the angle between the head end face of the wedge block 4B and the bottom face of the wedge block 4B is an acute angle. More preferably, the sharp edge of the second lock plate body 7C is blunted to make it easier to generate relative movement when contacting the head end face of the wedge block 4B.

[0077] More preferably, Figure 5 As shown, a mounting seat 1B is provided on the top surface of the cabinet 1 for mounting and fixing the limiting device 4. Figure 1 and Figure 2 A sandwich body 2 with a cover structure is arranged on the top of the cabinet 1 to cover all the limit devices 4 to prevent dust. Here, the sandwich body 2 and the cabinet 1 are connected by bolts or other detachable connections, which is convenient for disassembling the sandwich body 2 to replace and maintain the limit devices 4.

[0078] In some embodiments, Figure 1 and Figure 2 As shown, the storage device 100 also includes a cabinet door 3. The cabinet door 3 can be a push-pull or draw-close cabinet door, and is movably connected to the cabinet body 1. The cabinet door 3 can be freely switched between the closed state and the open state to achieve the blocking or unblocking of the cavity 1C. In order to more conveniently realize the opening or closing of the cabinet door 3, a front side of the cabinet door 3 is provided with a Fig. 9 Door handle 3C shown.

[0079] More preferably, the side edge of the cabinet door 3 is hinged to the edge of the cavity opening of the inner cavity 1C. The cabinet door 3 is composed of a plurality of door units; each door unit blocks a corresponding first storage cavity 1C1. When the door unit blocks the first storage cavity 1C1, it can simultaneously form a detachable buckle with the first partition 6 and the cabinet body 1. The purpose of this arrangement is to ensure that when a door unit is opened and the goods stored in the first storage cavity 1C1 are taken out, the first partition 6 always remains fixed in the second unfolded state, thereby ensuring the privacy of the adjacent first storage cavity 1C1. For example Fig.16 As shown, when the door unit on the left is opened and the door unit on the right is closed, the door unit on the right is buckled with the cabinet body 1 and the first partition 6, so the first partition 6 will remain fixed in the second unfolded state. Therefore, when taking the goods from the first storage cavity 1C1 on the left, the first storage cavity 1C1 on the right is still in a fully enclosed private space, and vice versa, to ensure that they do not interfere with each other.

[0080] It should be pointed out here that multiple first storage cavities 1C1 and door units can be arranged side by side along the X-axis and correspond one to one. The side edges of the door units can be hinged to the upper edges of the cabinet 1, and can be connected to the side edges of the cabinet 1 and the first partition 6 by rotating up and down to open and close. This connection method is not shown in the schematic diagram.

[0081] A preferred structure given in this application is that the door unit of the cabinet door 3 is as follows Figure 2 The left cabinet door 31 and the right cabinet door 32 are mirror images of each other. Figure 2 and Fig.16 As shown, a first partition 6 is provided; the first partition 6 divides the inner cavity 1C into two first storage cavities 1C1 in the second unfolded state. The side edges of the cabinet body 1 are hinged to the side edges of the left cabinet door 31 and the side edges of the right cabinet door 32 respectively. Figure 8 The upper edges of the back sides of the left cabinet door 31 and the right cabinet door 32 are both provided with first door latches 3A, and the side edges away from the hinges are both provided with second door latches 3B. The left cabinet door 31 and the right cabinet door 32 each block a corresponding first storage cavity 1C1.

[0082] like Figure 5The upper edge of the front face of the cabinet body 1 is symmetrically provided with a first cabinet latch 1D. The first partition plate 6 also includes Figure 7 The second plate latch 6E is symmetrically arranged on the first cover plate 6B. The first door latch 3A and the first cabinet latch 1D, as well as the second door latch 3B and the second plate latch 6E correspond to each other, and can be detachably fastened to each other in the form of magnetic locks or elastic locks, so as to be opened and closed according to user needs.

[0083] It should be pointed out here that two adjacent door units, such as Figure 2 The left cabinet door 31 and the right cabinet door 32 are shown. When the left cabinet door 31 is opened to take out the goods, in order to prevent the user who takes out the goods at this time from peeping into the privacy of the goods in the first storage cavity 1C1 blocked by the right cabinet door 32, or entering the first storage cavity 1C1 blocked by the right cabinet door 32 by other means, the cantilever beam body 1E also includes Figure 3 The beam sealing plate 1E1 shown in FIG. Figure 6 The support plate shown is vertically arranged on the head of the cantilever beam ridge 1E2 and extends to both sides of the cantilever beam ridge 1E2, and is used in conjunction with the first sealing plate 6B at the head end of the first partition body 6A. When the left cabinet door 31 is opened, it can form a larger surface contact with the side of the right cabinet door 32 that is closed at this time, thereby better ensuring the privacy of the first storage cavity 1C1 in the area where the right cabinet door 32 is located.

[0084] A preferred layout of the present application is as follows Figure 2 As shown in the figure, a total of one first partition 6 is arranged in the inner cavity 1C, and three second partitions 7 are arranged symmetrically on both sides of the first partition 6. In this way, the entire inner cavity 1C can be divided into at most Fig.14 and Fig.15 The 2×4 second storage compartments shown in the figure are used to store the goods in different areas. When taking out the goods, they are also taken out in order, that is, the goods located at the cavity opening of the inner cavity 1C are taken out first, and then the second partitions 7 at the rear are switched to the second storage state in turn, so as to take out the goods at the rear. When some goods are large, one of the second partitions 7 can be selectively switched to the second storage state to merge the adjacent second storage compartments to store the larger goods. When some larger goods are stored, they can be Fig.16 and Fig.17 As shown, first, all the second partitions 7 are switched to the second storage state, and then Fig.18 and Fig.19 As shown, the first partition 6 is switched to the first storage state, that is, all the partitions are stored to cancel the partition of the inner cavity 1C, so as to store and access larger goods; if it is necessary to re-partition the space of the inner cavity 1C, it can be as follows Fig.14 and Fig.15As shown, the first partition 6 is first switched to the second expanded state, and then the second partition 7 is selectively switched to the second expanded state according to access requirements.

[0085] Another preferred layout of the present application is to set a total of 1 first partition 6 in the inner cavity 1C, and set 1 second partition 7 on both sides of the first partition 6 symmetrically, so that the entire inner cavity 1C can be divided into 2×2 second storage compartments at most, and cabinet doors 3 are set at the head and tail ends of the cabinet body 1, so that users can take goods in any second storage compartment according to their needs without having to take them in order, thereby increasing convenience. A schematic diagram of this structure is not given, and technical personnel in this field can design and produce it according to the needs of the usage scenario and related descriptions.

[0086] Fig.21 This is an application scenario of the storage device 100. Multiple storage devices 100 are arranged in an array to form a storage cabinet assembly 1000. The storage cabinet assembly 1000 can be a storage center composed of multiple express containers, or a storage area of ​​other containers. The storage cabinet assembly 1000 also includes a control unit 200. Relevant personnel can set parameters for the control unit 200 to control the storage / expansion status of the first partition 6 and the second partition 7 in each storage device 100, so as to divide different space partitions to adapt to the storage of related goods, and can monitor the internal storage conditions of the relevant storage devices 100 to determine whether there are goods stored, etc., thereby increasing the intelligence of the storage cabinet assembly 1000.

[0087] As shown in this application and the claims, the words “a”, “an”, “an” and / or “the” are not intended to refer to the singular but include the plural unless the context clearly indicates an exception.
