Description

A box assembly and a storage assembly

[0001] Cross Reference to Related Applications

[0002] The present disclosure claims priority to the Chinese patent application No. 2024223117589, filed on September 20, 2024, and entitled "A box assembly and a storage assembly", the entire content of which is incorporated herein by reference. TECHNICAL FIELD

[0003] The present disclosure relates to the field of tools, in particular to a box assembly and a storage assembly. BACKGROUND

[0004] At present, since the number of accessories such as bits that can be used in cooperation with tools such as screwdrivers is large, there are storage boxes for storing bits.

[0005] Since the current storage boxes are independent of each other, when multiple storage boxes are used at the same time, the placement between the storage boxes is random, which leads to the problem of messy workbench surface.

[0006] Practical new type content

[0007] The purpose of the present disclosure is to provide a box assembly and a storage assembly, which can be connected by magnetic attraction during the use of the storage box, so as to better facilitate and regular placement, and improve the neatness of the workbench surface.

[0008] Embodiments of the present disclosure are implemented as follows:

[0009] In a first aspect, the embodiments of the present disclosure provide a box assembly, comprising a storage box, wherein the storage box comprises a box body and a magnet arranged on the box body, the opposite upper surface and lower surface of the box body have magnetic force, and at least two opposite side surfaces of the box body have magnetic force.

[0010] In the technical solution, the upper surface and the lower surface of the box body have magnetic force due to the magnets, so that when multiple storage boxes are placed at the same time, the storage boxes can be stacked vertically by magnetic force, and the storage boxes can be arranged in order to improve the neatness of the workbench. The at least two opposite side surfaces of the box body have magnetic force due to the magnets, so that when multiple storage boxes are used at the same time, the storage boxes can be connected horizontally by magnetic force, and the storage boxes can be arranged in order to improve the neatness of the workbench. Compared with the mechanical structure, the magnetic connection between the storage boxes is more convenient.

[0011] In a second aspect, the embodiments of the present disclosure provide a box assembly, which includes at least two storage boxes, each of which includes a box body and a magnet arranged on the box body. The opposite upper surface and the lower surface of the box body have magnetic force, so that the storage boxes have magnetic attraction when stacked. The at least two opposite side surfaces of the box body have magnetic force, so that the storage boxes have magnetic attraction when horizontally connected.

[0012] The box assembly provided by the technical solution includes at least two storage boxes, and the magnets in the storage boxes make the storage boxes have magnetic force on the upper surface, the lower surface and the opposite side surfaces. When the storage boxes are placed, the storage boxes can be stacked with other storage boxes by magnetic force, and the storage boxes can be horizontally connected with other storage boxes by magnetic force. By connecting the storage boxes, the problem of messy workbench caused by random placement of the storage boxes can be improved.

[0013] In some optional embodiments, the magnets are arranged at the edges of the box body, and the axial direction of each magnet extends from the upper surface to the lower surface.

[0014] In the technical solution, the edges of the box body include the side surfaces of the box body and the corner positions of the box body. By arranging the magnets at the edges of the box body and arranging the axial direction of the magnets to extend from the upper surface to the lower surface (i.e., the end surface of the magnet faces the upper surface of the box body or the lower surface of the box body), the magnets can easily make the side surfaces of the box body have magnetic force, and the magnets can easily make the upper surface and the lower surface of the box body have magnetic force, so that relatively fewer magnets can be used to stack or horizontally connect the storage boxes by magnetic force.

[0015] In some optional embodiments, the magnets include four magnets, the projections of the four magnets on the upper surface form a quadrilateral, one end of the magnet makes the upper surface have magnetic force, and the other end of the magnet makes the lower surface have magnetic force.

[0016] In the technical solution, the magnets are arranged at the edges of the box body, and the projections of the four magnets on the upper surface form a quadrilateral. Therefore, at least two opposite sides of the box body are provided with magnets, so that the at least two opposite sides of the box body have magnetic force. Since one end of the magnet makes the upper surface have magnetic force and the other end makes the lower surface have magnetic force, that is, the whole magnet is arranged vertically, the number of magnets can be reduced, and installation is facilitated.

[0017] In some optional embodiments, the box body is square, and the four magnets are arranged at the four corners of the box body, respectively.

[0018] In the technical solution, the magnets are arranged at the four corners of the box body, respectively. Therefore, each magnet can make the two adjacent sides of the box body have magnetic force, and make the upper and lower surfaces of the box body have magnetic force. The four magnets can make the two opposite sides of the box body in two directions have magnetic force, that is, the four sides of the box body have magnetic force. Therefore, the horizontal splicing mode between the storage boxes is more diverse, and use is more convenient.

[0019] In some optional embodiments, among the four magnets, the magnetic poles of the two adjacent magnets in the circumferential direction of the upper surface are opposite.

[0020] According to the arrangement of the magnets in the technical solution, the upper surface of one box body can be connected with another box body, and the lower surface of the box body in another storage box can also be connected. Therefore, any surface of the adjacent two storage boxes can be overlapped, so that the overlapping mode between the storage boxes is more diverse, and use is more convenient. Similarly, one side of the storage box can be horizontally spliced with any one of the two opposite sides corresponding to the box body in another storage box, and the horizontal splicing mode is also more flexible.

[0021] In some optional embodiments, two magnets are included, and the axial direction of each magnet extends from the upper surface to the lower surface; and a ferromagnetic structural member is further included.

[0022] The box body is square, and the two magnets and the ferromagnetic structural member are arranged at the four corners of the box body, respectively. In the circumferential direction of the upper surface, the magnets and the ferromagnetic structural member are arranged alternately.

[0023] In some optional embodiments, at least two opposite sides of the box body are provided with the magnets.

[0024] In the technical solution, the magnets are arranged at the at least two opposite sides of the box body, so that the at least two opposite sides of the box body have magnetic force.

[0025] In some alternative embodiments, the box is square, and the box has two opposite sides in length and width directions, and the four sides of the box are provided with the magnets.

[0026] In the above technical solution, the four sides of the box are provided with the magnets, so that the four sides of the magnet have magnetic force, and any side of the storage box can be spliced with the side of the box in another storage box.

[0027] In some alternative embodiments, the number of the magnets is four, and the projections of the four magnets on the upper surface form a quadrilateral.

[0028] In some alternative embodiments, the number of the magnets on each side is two, and the magnetic poles of the two adjacent magnets are opposite; and the magnets are symmetrically arranged along the center line of the upper surface.

[0029] According to the arrangement of the magnets in the above technical solution, one side of the storage box can be horizontally spliced with any side of the corresponding two opposite sides in another storage box, and the splicing direction is not limited.

[0030] In some alternative embodiments, the magnets are arranged at the edges of the box, and the axial direction of each magnet extends along the direction of the two opposite sides.

[0031] In the above technical solution, the axial direction of each magnet extends along the direction of the two opposite sides, that is, the magnet extends from one side to the other opposite side, and the magnet is transversely arranged on the box.

[0032] In some alternative embodiments, one end of the magnet makes one side of the box have magnetic force, and the other end makes the other opposite side of the box have magnetic force.

[0033] In the above technical solution, one end of the magnet makes one side of the box have magnetic force, and the other end makes the other opposite side of the box have magnetic force, that is, the whole magnet is transversely arranged, which can reduce the number of magnets and facilitate installation.

[0034] In some alternative embodiments, the box is square, and the number of the magnets is four, and the end portions of the four magnets are projected on the four corners of the side.

[0035] In the above technical solution, the projection of the magnet on the side of the box is located at the four corners of the side, and the magnet is transversely arranged, so that two magnets can make the same side have magnetic force, so that when the boxes in two storage boxes are connected by magnetic force, the connection is more reliable. Four magnets can make the six sides of the square box have magnetic force, and a smaller number of magnets can realize the splicing or overlapping of each side.

[0036] In some alternative embodiments, the magnetic poles of two adjacent magnets are opposite along the circumferential direction of the arrangement of the four magnets.

[0037] In the above technical solution, either side of a receiving box can be horizontally spliced with either of the two opposite sides of the box body in another receiving box, and the splicing direction is not limited.

[0038] In some alternative embodiments, the box body includes a box body configured to accommodate accessories, and connecting members arranged at both ends of the box body in the length direction, and the magnets are arranged in the connecting members, and the upper surface, the lower surface, and the two opposite sides in the width direction of the connecting members all have magnetic force.

[0039] In the above technical solution, the box body is configured to accommodate accessories, and the magnets are arranged in the connecting members (at both ends of the box body in the length direction), which can reduce the influence of the installation of the magnets on the accommodation of the accessories.

[0040] In some alternative embodiments, the connecting members are detachably connected to the box body.

[0041] In the above technical solution, the connecting members can be replaced, and the connecting members and the box body can be manufactured separately, so that the same connecting members can be assembled with box bodies of different lengths.

[0042] In some alternative embodiments, along the width direction of the box body, the two ends of the connecting members are connected to the box body from the two opposite sides of the box body.

[0043] In some alternative embodiments, the two ends of the connecting members are connected to the box body by screws.

[0044] In some alternative embodiments, the two ends of the connecting members and the heads of the two screws form grooves and protrusions, respectively; and the grooves and the protrusions can be matched in structure.

[0045] In the above technical solution, one end of the connecting member forms a groove with the head of a screw, and the other end forms a protrusion with the head of a screw; when the sides of the box bodies in two receiving boxes are spliced, positioning can be achieved by matching the grooves and the protrusions.

[0046] In some alternative embodiments, the grooves and the protrusions are arranged alternately in the circumferential direction of the box body.

[0047] In the above technical solution, the grooves and the protrusions are arranged alternately in the axial direction of the box body, so that when the side of a box body is spliced with either of the two opposite sides of the corresponding box body in another receiving box, positioning can be achieved by the groove and the protrusion structure.

[0048] In some alternative embodiments, the connecting piece is provided with a cavity, and the magnet is arranged in the cavity.

[0049] In some alternative embodiments, the cavity has an opening arranged in the connecting piece, and the magnet is inserted into the cavity from the opening and bonded to the inner wall of the cavity.

[0050] In some alternative embodiments, the connecting piece is provided with an upper protrusion and a lower protrusion, the end surface of the upper protrusion is the upper surface, and the end surface of the lower protrusion is the lower surface; one end of the cavity penetrates through the upper protrusion to form the opening, and the other end is located in the lower protrusion.

[0051] In the above technical solution, the cavity configured to mount the magnet is arranged in the upper protrusion and the lower protrusion of the connecting piece, which can reduce the volume of the connecting piece and save materials.

[0052] In some alternative embodiments, the distance between one end of the magnet and the upper surface is 0-2mm, and the distance between the other end of the magnet and the lower surface is 0-2mm.

[0053] In the above technical solution, the distance between the magnet and the upper surface and the distance between the magnet and the lower surface are within the above range, which can make the upper surface and the lower surface have a stronger magnetic force.

[0054] In some alternative embodiments, the end surface of the upper protrusion is flush with one surface of the box body, and the end surface of the lower protrusion is flush with another surface of the box body.

[0055] In the above technical solution, when the two receiving boxes are overlapped by contacting the upper and lower surfaces of the box bodies, there is almost no gap between the two box bodies, which can make the magnetic attraction of the two box bodies stronger, so as to better the magnetic attraction when overlapped.

[0056] In some alternative embodiments, the box body has a square structure, the upper surface of the box body is provided with protruding structures and recessed structures that can cooperate with each other in structure, the protruding structures and the recessed structures are distributed at the four corners of the rectangle, and the protruding structures and the recessed structures are alternately arranged along the circumference of the rectangle.

[0057] In the above technical solution, since the upper surface of the box body is provided with protruding structures and recessed structures that can cooperate with each other in structure, when the box bodies in the two receiving boxes are spliced, the protruding structures in one box body can cooperate with the recessed structures in the other box body, thereby playing a positioning role. Since the protruding structures and the recessed structures are alternately arranged, the stacking direction of the upper surfaces of the box bodies in the two receiving boxes is not limited, and the stacking of the receiving boxes is more convenient.

[0058] In some optional embodiments, the upper surface of the box body is concavely provided with an accessory groove configured to accommodate an accessory.

[0059] In a third aspect, the embodiments of the present disclosure provide a storage assembly, a host storage bin, and the box assembly provided in the first aspect or the second aspect, the host storage bin is located outside the box body and is detachably connected with the box body.

[0060] In combination with the third aspect, in some optional embodiments, the host storage bin is provided with a magnetic body, and the host storage bin is detachably connected with the box body through the magnetic body and the magnet. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0091] In order to make the objects, technical solutions, and advantages of the embodiments of the present disclosure clearer, the following will be combined with the accompanying drawings for the embodiments of the present disclosure to make a clear and complete description of the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure and not all the embodiments. The components of the embodiments of the present disclosure described and shown in the accompanying drawings can be arranged and designed in various different configurations.

[0092] Therefore, the following detailed description of the embodiments of the present disclosure provided in the accompanying drawings is not intended to limit the scope of the claimed present disclosure, but only represents selected embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present disclosure without creative labor are within the scope of protection of the present disclosure.

[0093] It should be noted that similar reference numerals and letters in the following drawings represent similar items, and therefore, once an item is defined in one drawing, it need not be optionally defined and explained in subsequent drawings.

[0094] In the description of the present disclosure, it should be noted that the terms "center", "upper", "lower", "vertical", "horizontal", "inner", "outer", and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the application is usually placed, and are only for the convenience of describing the present disclosure and simplifying the description, and therefore cannot be understood as indicating or implying that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present disclosure. In addition, the terms "first", "second", "third", and the like are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0095] In addition, the terms "horizontal", "vertical", "overhanging", and the like do not mean that the components must be absolutely horizontal or overhanging, but can be slightly inclined. For example, "horizontal" only means that it is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0096] In the description of the present disclosure, it also needs to be explained that, unless explicitly specified and limited, the terms "arrange", "mount", "connect", "connect" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium, or the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present disclosure can be understood according to the specific circumstances.

[0097] The present disclosure provides a storage assembly, as shown in FIGS. 1-4, comprising a host storage bin 200 and a cartridge assembly 10. The host storage bin 200 is configured to store a host. As shown in FIGS. 5-14, the cartridge assembly 10 comprises a storage cartridge 100, which is configured to accommodate accessories. Different hosts can be combined with different storage cartridges 100 or different accessories in the storage cartridge 100, or the same host can be combined with different storage cartridges 100 or different accessories in the storage cartridge 100, to adapt to different use requirements. In the storage assembly provided by the present disclosure, the host that can be stored in the host storage bin 200 can be a screwdriver, an electric screwdriver, or other tools that can be used with replaceable accessories. Alternatively, the host storage bin 200 is located outside the storage cartridge 100, and the user can directly take and place the host from the host storage bin 200, which is more convenient to operate. Alternatively, the host storage bin 200 is detachably connected with the storage cartridge 100, so that the user can combine the host storage bin 200 with the storage cartridge containing the accessories needed for use, and carry and use it conveniently.

[0098] As shown in FIGS. 5-23, the storage cartridge 100 comprises a cartridge body 110 and a magnet 120 arranged on the cartridge body 110. The upper surface and the lower surface of the cartridge body 110 have magnetic force, and at least two opposite side surfaces of the cartridge body 110 have magnetic force. It is not difficult to understand that the cartridge body 110 is configured to accommodate accessories, and the magnet 120 can be configured to connect the cartridge body 110 with other objects. Alternatively, the host storage bin 200 is detachably connected with the cartridge body 110. The cartridge body 110 has an accessory slot 1113 (see FIG. 10) configured to accommodate accessories. The accessory slot 1113 should have an access opening 11131 to configure the accessories to be taken out. When the access opening 11131 is placed upward, the upper surface of the cartridge body 110 is the surface above in the cartridge body 110, and the lower surface is the surface opposite to the upper surface. When the access opening 11131 is placed upward, the side surface of the cartridge body 110 is the surface extending in the vertical direction. Taking the case that the cartridge body 110 is square, i.e. the cartridge body 110 is generally cuboid, the cartridge body 110 has one upper surface, one lower surface, and four side surfaces.

[0099] It should be noted that the upper surface and the lower surface of the box body 110 have magnetic force, which means that the box body 110 can connect other objects (such as another box body 110) on the upper surface thereof by magnetic force, and can also connect other objects (such as another box body 110) on the lower surface thereof by magnetic force; the at least two opposite sides of the box body 110 have magnetic force, which means that the box body 110 can connect other objects (such as another box body 110) on one side thereof by magnetic force, and can also connect other objects (such as another box body 110) on the other opposite side thereof by magnetic force. The magnetic force of the upper surface, the lower surface and the side of the box body 110 comes from the magnet 120, and the magnetic force of the upper surface, the lower surface and the side of the box body 110 can be directly generated by the magnetic field of the magnet 120, or can be generated by the object magnetized by the magnet 120, for example, in some embodiments, a ferromagnetic structural member is arranged on the upper surface of the box body 110, and the ferromagnetic structural member can also be magnetized under the action of the magnet 120 to generate magnetic force on other objects (such as the box body 110 in another storage box 100). In another embodiment, two box bodies 110 are connected by the mutual attraction of the magnets 120 in the box bodies 110. In some embodiments, the magnet 120 in one box body 110 can attract the ferromagnetic structural member (such as a metal structural member of iron, nickel, cobalt, etc.) in another box body 110, thereby connecting the two box bodies 110. Alternatively, the ferromagnetic structural member can be a columnar structure or a sheet structure. In the embodiment in which the ferromagnetic structural member is a columnar structure, the axial direction of the ferromagnetic structural member can extend from the upper surface to the lower surface. In the case where the ferromagnetic structural member is a sheet structure, the ferromagnetic structural member can be adhered to the upper surface and the lower surface of the box body 110, or recesses can be provided on the upper surface and the lower surface of the box body 110 to accommodate the ferromagnetic structural member.

[0100] Alternatively, a magnetic body is arranged on the host storage bin 200, and the host storage bin 200 and the box body 110 are detachably connected by the magnetic body and the magnet 120. The magnetic body is an object that can generate magnetic force with the magnet, for example, the magnetic body can be a magnet, or a ferromagnetic body structural member of iron, nickel, etc.

[0101] In some embodiments of the present disclosure, as shown in FIGS. 1, 2 and 4, the box assembly 10 has one storage box 100; in another embodiment, as shown in FIGS. 3, 8 to 14, the box assembly 10 has two storage boxes 100; in other embodiments, as shown in FIGS. 5 to 7, the box assembly 10 can also include more than two storage boxes 100.

[0102] Since the upper surface, the lower surface and the side surface of the box body 110 of the storage box 100 have magnetic force, when two or more storage boxes 100 are included in the box assembly 10, the box bodies 110 of different storage boxes 100 can be connected to each other, and the connection forms include splicing in the horizontal direction (i.e., as shown in FIGS. 8 to 10, the side surfaces of two box bodies 110 are attracted to and contact each other under the action of magnetic force) and stacking in the vertical direction (i.e., as shown in FIGS. 7, 11 to 14, the upper surface of one box body 110 is attracted to and contacts the upper surface or the lower surface of another box body 110 under the action of magnetic force). Therefore, when the box assembly 10 is used, the storage boxes 100 can be connected to each other according to the use needs, for example, during the use of the storage boxes 100, the storage box 100 containing the batch head to be used is stacked above other storage boxes 100; or the plurality of storage boxes 100 containing the batch head to be used are spliced in the horizontal direction, so that the storage boxes 100 are arranged in order and the neatness of the workbench surface is improved.

[0103] In some embodiments of the present disclosure, the structures of the storage boxes 100 in the box assembly 10 can be the same, i.e., the structures of any two storage boxes 100 are the same. In some other embodiments, as shown in FIG. 10, the structures of the storage boxes 100 can also be different. In the embodiment shown in FIG. 10, the main reason for the existence of two box bodies 110 is that the types of the accessories contained are different. Therefore, the main difference between the storage boxes 100 lies in the difference in the structure of the accessory groove 1113, and the setting position and the setting mode of the magnet 120 configured to realize the connection between the two box bodies 110 do not change with the types of the accessories contained in the box body 110. In the embodiment shown in FIG. 10, in the box body 110 of the storage box 100 configured to contain the batch head, the batch head is arranged at a fixed position in the batch head groove; and in the box body 110 of the storage box 100 configured to contain the electric grinder head, the electric grinder head is freely movable in the accessory groove 1113. Therefore, in the box body 110 configured to contain the electric grinder head, a cover plate (not shown in the figure) can be arranged on the access opening 11131 of the accessory groove 1113 to cover the access opening 11131 of the accessory groove 1113 to prevent the accessories from falling out. In the storage box 100 configured to contain the batch head and the storage box 100 configured to contain the electric grinder head shown in FIG. 10, the setting position and the setting mode of the magnet 120 configured to realize the connection between the box body 110 and other box bodies 110 are the same, so that the storage box 100 configured to contain the batch head and the storage box 100 configured to contain the electric grinder head can also be connected.

[0104] In some other embodiments, the structure of the box body 110 can also be as shown in FIG. 28. The box body 110 comprises an outer shell 114 and an inner liner 115 received in the outer shell 114. The accessory slot 1113 (not shown in the figure) is arranged on the inner liner 115. The accessories can be accessed by pulling out the inner liner 115 from the outer shell 114. In this embodiment, the upper surface and the lower surface of the box body 110 are two opposite surfaces of the outer shell 114. That is, when the box 100 is used, the surface of the outer shell 114 above the access opening 11131 of the accessory slot 1113 is the upper surface of the box body 110, and the surface opposite to the upper surface is the lower surface of the box body 110. When the access opening 11131 is placed upward, the surface of the outer shell 114 extending in the vertical direction is the side surface. The outer shell 114 is provided with a magnet 120, so that the upper surface and the lower surface of the outer shell 114 have magnetic force, and the two opposite side surfaces of the outer shell 114 also have magnetic force.

[0105] In some embodiments of the present disclosure, the axial direction of the magnet 120 configured to realize the connection between the two box bodies 110 extends from the upper surface of the box body 110 to the lower surface of the box body 110. That is, the magnet 120 is arranged vertically between the upper surface and the lower surface, and the magnet 120 is arranged at the edge of the box body 110, so that the magnetic force between the two box bodies 110 is larger when they are connected to each other, and the connection is more stable. The axial direction of the magnet 120 is the direction in which the N pole points to the S pole. When the magnet 120 is arranged vertically, the edge of the box body 110 includes the position close to the side surface of the box body 110 and the position close to the top corner of the box body 110. The magnet 120 arranged at the edge of the box body 110 includes the way that the magnet 120 is located inside the box body 110, and also includes the way that the magnet 120 is directly bonded to the side surface or the upper surface or the lower surface of the box body 110. It also includes the way that the magnet 120 is embedded in the box body 110 (as shown in FIG. 21). The surface of the magnet 120 can be flush with the side surface or the upper surface or the lower surface of the box body 110, or it can not be flush. As long as the surface and the side surface have magnetic force, it is acceptable.

[0106] When the magnet 120 is arranged vertically, the end surface of the magnet 120 faces the upper surface of the box body 110 or the lower surface of the box body 110, so that the magnetic force of the upper surface and the lower surface of the box body 110 is stronger. When the box 100 is stacked, the two box bodies 110 have a larger attractive force.

[0107] The direction perpendicular to the upper surface or lower surface of the box body 110 is the height direction of the box body 110, that is, the direction indicated by the arrow Z in FIG. 19. In the case where the magnets 120 are vertically arranged, as long as one magnet 120 or a column of magnets 120 arranged in the height direction of the box body 110 simultaneously magnetizes the upper surface, the lower surface, and two adjacent side surfaces of the box body 110, the magnet 120 or the column of magnets 120 is considered to be located close to the top corner of the box body 110; if one magnet 120 or a column of magnets 120 arranged in the height direction of the box body 110 simultaneously magnetizes the upper surface, the lower surface, and one adjacent side surface of the box body 110, the magnet 120 or the column of magnets 120 is considered to be located close to the side surface of the box body 110. The column of magnets 120 can include two magnets 120 or two or more vertically arranged magnets 120; preferably, the axes of the column of magnets 120 arranged in the height direction of the box body 110 are collinear.

[0108] In the case where a column of magnets 120 is arranged in the height direction of the box body 110, the magnet 120 close to the upper surface magnetizes the upper surface of the box body 110, and the magnet 120 close to the lower surface magnetizes the lower surface of the box body 110.

[0109] In the case where one magnet 120 is arranged in the height direction of the box body 110, one end of the magnet 120 is close to the upper surface of the box body 110, and the other end of the magnet 120 is close to the lower surface of the box body 110, that is, the same magnet 120 is used to magnetize the upper surface and the lower surface of the box body 110.

[0110] Optionally, in some embodiments in which the magnets 120 are vertically arranged, as shown in FIGS. 18 and 24, four magnets 120 are arranged at the edges of the box body 110, and the projections of the four magnets 120 on the upper surface of the box body 110 form a quadrilateral. It is understood that in the case where the magnets 120 are vertically arranged, the projection of the magnet 120 on the upper surface of the box body 110 is a point, and the projections of the four magnets 120 on the upper surface of the box body 110 form a quadrilateral means that the projections of the four magnets 120 can form a quadrilateral. Optionally, two magnets 120 can be located at one side surface of the box body 110, and the other two magnets 120 can be located at the other opposite side surface of the box body 110, so as to realize the vertical overlap of two box bodies 110 and the horizontal splicing of the two box bodies 110.

[0111] Optionally, in the case that the box 110 is also square, as shown in the embodiment of FIG. 14, the four magnets 120 can also be arranged at positions close to one side of the box 110 respectively (i.e., the four sides of the box 110 in the length and width directions are provided with the magnets 120), so that the two boxes 110 can be overlapped not only in the vertical direction, but also in two horizontal directions; as shown in the embodiments of FIGS. 18 and 24, the four magnets 120 can also be arranged at one corner of the box 110 respectively, i.e., the four magnets 120 are arranged at the four corners of the box 110 respectively, and the projections of the four magnets 120 on the upper surface of the box 110 can form a rectangle or an approximate rectangle, so that the two boxes 110 can be overlapped not only in the vertical direction, but also in two horizontal directions, i.e., the splicing mode shown in FIGS. 8 and 9. Among them, the two horizontal directions can be understood as the length direction and the width direction of the box 110, and the size of the box 110 in the length direction is greater than that in the width direction. As shown in FIG. 18, the length direction of the box 110 is the direction indicated by the arrow X, and the width direction of the box 110 is the direction indicated by the arrow Y. Of course, in other embodiments, the edges of the box 110 can also be provided with other numbers of magnets 120.

[0112] Optionally, among the four magnets 120, the adjacent two magnets 120 have opposite magnetic poles in the circumferential direction of the upper surface of the box 110. For example, the N pole of one magnet 120 is located at one corner of the quadrilateral, and the S pole of another magnet 120 is located at another adjacent corner of the quadrilateral. In this embodiment, more stacking modes of the two boxes 110 in the vertical direction can be achieved. Taking the magnetic pole arrangement mode of the magnet 120 shown in FIG. 24 as an example, when the upper surfaces of the two boxes 110 are in contact with each other to achieve stacking, the first end in the length direction of one box 110 can be aligned with the first end in the length direction of another box 110, or the second end in the length direction of one box 110 can be aligned with the first end in the length direction of another box 110; similarly, when the upper surface of one box 110 and the lower surface of another box 110 are in contact with each other to achieve stacking, the first end in the length direction of one box 110 can be aligned with the first end in the length direction of another box 110, or the second end in the length direction of one box 110 can be aligned with the first end in the length direction of another box 110.

[0113] The two box bodies 110 can be stacked by the upper surfaces contacting each other, and the first end of one box body 110 can correspond to the first end of another box body 110, or the second end of one box body 110 can correspond to the first end of another box body 110. Meanwhile, one box body 110 can also be stacked with another box body 110 by the upper surface and the lower surface contacting each other, and in this stacking mode, the first end of one box body 110 can correspond to the first end of another box body 110, or the second end of one box body 110 can correspond to the first end of another box body 110, that is, the stacking direction of the two box bodies 110 is not limited. Similarly, the direction in which the box bodies 110 are spliced in the horizontal direction is not limited, that is, one box body 110 can be spliced with another box body 110 by the first side surface contacting the second side surface, and the first end of the box body 110 in the length direction can correspond to the first end of another box body 110 in the length direction, or the first end of the box body 110 in the length direction can correspond to the second end of another box body 110 in the length direction. In the case where one box body 110 can be spliced with another box body 110 by the first side surface contacting the first side surface, the first end of the box body 110 in the length direction can correspond to the first end of another box body 110 in the length direction, or the first end of the box body 110 in the length direction can correspond to the second end of another box body 110 in the length direction. The first side surface and the second side surface of the box body 110 are two opposite side surfaces.

[0114] In some embodiments, the box body 110 includes two magnets 120 and two ferromagnetic structural members (columnar structural members with ferromagnetism, such as iron columns, nickel columns, cobalt columns, etc.), and the axial direction of each magnet 120 and each ferromagnetic structural member extends from the upper surface to the lower surface. The box body 110 is square, and the two magnets 120 and the two ferromagnetic structural members are respectively arranged at the four corners of the box body 110, and on the circumferential direction of the upper surface of the box body 110, the magnets 120 and the ferromagnetic structural members are alternately arranged. In this embodiment, the end of the magnet 120 close to the upper surface of the box body 110 makes the upper surface of the box body 110 have a magnetic force, and the end of the magnet 120 close to the lower surface of the box body 110 makes the lower surface of the box body 110 have a magnetic force. In this embodiment, since the two magnets 120 and the two ferromagnetic structural members are respectively arranged at the four corners of the box body 110, and on the circumferential direction of the upper surface of the box body 110, the magnets 120 and the ferromagnetic structural members are alternately arranged, that is, the projection of the arrangement positions of the two magnets 120 and the two ferromagnetic structural members on the upper surface of the box body 110 is approximately rectangular, and the two adjacent corners in the rectangle are respectively provided with a magnet 120 and a ferromagnetic structural member, therefore, the stacking direction of the two box bodies 110 in this embodiment is not limited, and similarly, the direction in which the box bodies 110 are spliced in the horizontal direction is also not limited.

[0115] Of course, in another embodiment, the two magnets 120 at the first end of the length direction of the box body 110 are both S-pole magnets, and the two magnets 120 at the second end of the length direction of the box body 110 are both N-pole magnets. In this embodiment, when the two box bodies 110 are connected by the upper surfaces of the box bodies 110, the first end of one box body 110 should be aligned with the second end of the other box body 110.

[0116] It can be understood that, in the case where the magnets 120 are arranged at the corners of the box body 110 in the manner that the magnetic poles of the magnets 120 at adjacent corners are opposite (i.e., the arrangement of the magnets 120 shown in FIG. 24), the direction of the vertical overlap of the two box bodies 110 is not limited, and the direction of the horizontal connection of the two box bodies 110 is also not limited. The horizontal connection can be performed in the X direction and the Y direction (see FIGS. 9 and 10).

[0117] Optionally, in the embodiment where a column of magnets 120 is arranged along the height direction of the box body 110, the arrangement position of each column of magnets 120 and the magnetic poles of the magnets 120 at the corresponding height in each column of magnets 120 can also be arranged in the manner shown in FIG. 24. As shown in FIG. 26, in the embodiment where each column of magnets 120 includes two magnets 120 arranged along the height direction of the box body 110, there is a layer of magnets 120 (four magnets 120 in each layer) on the side close to the upper surface of the box body 110, and there is also a layer of magnets 120 on the side close to the lower surface of the box body 110. The arrangement manner of the magnetic poles of the two layers of magnets 120 is the arrangement manner of the magnetic poles shown in FIG. 24.

[0118] In some embodiments, as shown in FIG. 25, two magnets 120 are arranged at the position close to each side surface of the box body 110, and the attraction force generated when the two box bodies 110 are connected can be increased by using more magnets 120. Optionally, as shown in FIG. 26, the magnetic poles of the two adjacent magnets 120 are opposite, and the magnets 120 are symmetrically arranged along the center line of the upper surface of the box body 110. The center line of the upper surface of the box body 110 includes the center line in the length direction and the center line in the width direction. The distribution manner of the eight magnets 120 satisfies the symmetry with respect to the center line in the length direction and the center line in the width direction. It can be understood in combination with the arrangement manner of the magnetic poles shown in FIG. 24 that the direction of the horizontal connection and the vertical overlap of the two box bodies 110 in this embodiment is not limited.

[0119] In some other embodiments, as shown in FIG. 27, the magnets 120 can also be arranged laterally at the edges of the box 110, which means that the axial direction of the magnets 120 extends along the directions of two opposite sides. Specifically, the axial direction of the magnets 120 can extend along the directions of two opposite sides in the length direction, such as one end of the magnet 120 extending toward one side in the length direction of the box 110 and the other end of the magnet 120 extending toward the other side in the length direction of the box 110, or one end of the magnet 120 extending toward one side in the width direction of the box 110 and the other end of the magnet 120 extending toward the other side in the width direction of the box 110. In the state of lateral arrangement of the magnets 120, the edges of the box 110 include positions close to the upper surface or the lower surface of the box 110; the arrangement of the magnets 120 at the edges of the box 110 includes the manner that the magnets 120 are located inside the box 110; also includes the manner that the magnets 120 are directly bonded to the sides or the upper surface or the lower surface of the box 110; and also includes the manner that the magnets 120 are embedded in the box 110 and the surfaces of the magnets 120 are flush with the sides or the upper surface or the lower surface of the box 110.

[0120] In the case of lateral arrangement of the magnets 120, as long as one magnet 120 or one row of horizontally arranged magnets 120 makes at least one side of the box 110 have magnetic force and at least one of the upper surface and the lower surface of the box 110 have magnetic force, the magnet 120 or the row of magnets 120 is considered to be located close to the edges of the box 110. The row of horizontally arranged magnets 120 can be a row of magnets 120 arranged along the width direction of the box 110 or a row of magnets 120 arranged along the length direction of the box 110.

[0121] In some embodiments, the magnets 120 used are relatively long, and one end of the magnet 120 makes one side of the box 110 have magnetic force and the other end of the magnet 120 makes the other side of the box 110 have magnetic force.

[0122] In some embodiments, the box 110 is square in shape, and the number of the horizontally arranged magnets 120 is four, and the projections of the four magnets 120 on one side face are located at the four corners of the side face, i.e., each top corner of the side face of the box 110 corresponds to the projection of one magnet 120. In the embodiment shown in FIG. 27, the axial directions of the four magnets 120 are parallel to the width direction of the box 110, and the projections of the magnets 120 on the end side of the width direction of the box 110 are located at the top corner positions of the box 110 and can form a quadrilateral. In this embodiment, since the projections of the four magnets 120 on the side face are located at the top corner positions of the box 110 and can form a quadrilateral (as shown in FIG. 27, the projections of the four magnets 120 on the forward side face of the box 110 form a quadrilateral), i.e., each top corner position has the projection of one magnet 120, correspondingly, two magnets 120 are arranged at the position close to the upper surface of the box 110 and the position close to the lower surface of the box 110, respectively, and each magnet 120 can generate magnetic force on one of the upper surface and the lower surface of the box 110, and can also generate magnetic force on one side face and the other two opposite side faces of the box 110. Therefore, the two boxes 110 can not only be stacked in the vertical direction, but also be spliced in two horizontal directions.

[0123] Optionally, as shown in the embodiment of FIG. 27, the circumferential direction along the arrangement direction of the four magnets 120, i.e., the circumferential direction in which the projections of the forward side face of the box 110 form a quadrilateral, the magnetic pole directions of the adjacent two magnets 120 are opposite, so that the horizontal splicing and the vertical stacking directions of the adjacent two boxes 110 are not limited, and more splicing modes are provided. For example, one end of the box 110 in the length direction can not only be spliced with the other end of the box 110 in the length direction, but also be spliced with the other end of the box 110 in the length direction.

[0124] In the above embodiments, the magnet 120 can be a strip-shaped structural member, or a block-shaped or sheet-shaped structure as shown in FIG. 21, or other shaped structural members.

[0125] In some embodiments, as shown in FIG. 15, the box body 110 includes a box body 111 configured to accommodate the accessory, and a connecting piece 112 arranged at both ends of the box body 111 in the length direction, and the magnet 120 configured to realize the mutual connection between the box bodies 110 is arranged on the connecting piece 112. The magnet 120 enables the upper surface, the lower surface, and the two sides in the width direction of the connecting piece 112 to have magnetic force, and further enables the upper surface, the lower surface, and the two sides in the width direction of the box body 110 to have magnetic force. It is understood that the width direction of the box body 110 and the width direction of the box body 111 are the same direction, the length direction of the box body 110 and the length direction of the box body 111 are the same direction, and the height direction of the box body 110 and the height direction of the box body 111 are the same direction; the upper surface of the box body 110 includes the upper surface of the connecting piece 112 and the upper surface of the box body 111, and the upper surface of the connecting piece 112 and the upper surface of the box body 111 are located on the same side; the lower surface of the box body 110 includes the lower surface of the connecting piece 112 and the lower surface of the box body 111, and the lower surface of the connecting piece 112 and the lower surface of the box body 111 are located on the same side. In this embodiment, the accessory is arranged on the box body 111, and the magnet 120 is arranged on the connecting piece 112, so that the influence of the magnet 120 on the accessory can be reduced.

[0126] Optionally, the magnet 120 arranged on the connecting piece 112 also enables the side of the connecting piece 112 away from the box body 111 to have magnetic force, so that the two opposite sides of the box body 110 in the length direction also have magnetic force.

[0127] In some embodiments, the connection between the connecting piece 112 and the box body 111 is detachable. Since the connecting piece 112 and the box body 111 are detachable, on the one hand, the connecting piece 112 can be replaced conveniently; on the other hand, the box body 110 is divided into the connecting piece 112 and the box body 111, and the two can be manufactured separately to reduce the production difficulty.

[0128] Optionally, as shown in FIG. 20, along the width direction of the box body 111, the two ends of the connecting piece 112 are connected to the box body 111 from the two opposite sides of the box body 111. That is, one end of the connecting piece 112 is connected to one side of the box body 111 in the width direction, and the other end of the connecting piece 112 is connected to the other side of the box body 111 in the width direction. In other embodiments, the two ends of the connecting piece 112 can also be connected to the box body 111 from the two sides of the box body 111 in the length direction.

[0129] In some embodiments, when the two ends of the connecting piece 112 are connected to the box body 111 from the two opposite sides of the box body 111, a through hole is formed between the connecting piece 112 and the box body 111, so as to facilitate the suspension of the box body 110.

[0130] Optionally, in some embodiments, both ends of the connecting member 112 are connected to the box body 111 by screws 113, so as to facilitate disassembly and assembly of the two.

[0131] Optionally, in some embodiments, between the two ends of the connecting member 112 and the heads of the two screws 113, respectively, structural recesses 1121 and protrusions 1122 are formed. For example, one end of the connecting member 112 and the head of the screw 113 form a protrusion 1122, and the other end of the connecting member 112 and the head of the screw 113 form a recess 1121.

[0132] As shown in the embodiments of FIGS. 15-17, both ends of the connecting member 112 are provided with counterbores configured to accommodate the heads of the screws 113, wherein the edge of one counterbore protrudes outward to form a protrusion 1122, and the size of the protrusion 1122 can be accommodated by the other counterbore; the other counterbore can completely surround the head of the screw 113 inward to form a recess 1121. In other embodiments, both ends of the connecting member 112 are provided with counterbores configured to accommodate the heads of the screws 113; wherein the depth of one counterbore is less than the depth of the other counterbore, so that when the connecting member 112 is connected to the box body 111 using the screws 113, the head of the screw 113 at one end of the connecting member 112 is completely located in the corresponding counterbore and is lower than the surface of the connecting member 112, thereby forming a recess 1121 between the connecting member 112 and the head of the screw 113; the head of the screw 113 at the other end of the connecting member 112 is only partially located in the corresponding counterbore, and the head of the screw 113 is higher than the surface of the connecting member 112, thereby forming a protrusion 1122 between the connecting member 112 and the head of the screw 113.

[0133] Optionally, the edges of the counterbores forming the recesses 1121 can be chamfered to facilitate alignment between the recesses 1121 and the protrusions 1122.

[0134] It is not difficult to understand that the positions of the counterbores provided at both ends of the connecting member 112 can correspond to each other, so that when two box bodies 110 are spliced in the horizontal direction, the protrusion 1122 on the side of one box body 110 can cooperate with the recess 1121 on the side of the other box body 110, thereby serving as a positioning function.

[0135] Optionally, as shown in FIG. 18, the grooves 1121 formed by the connecting pieces 112 and the screws 113 are arranged alternately with the protrusions 1122 in the circumferential direction of the box body 110. The circumferential direction of the box body 110 can be understood as the direction along the closed edge of the upper surface or the lower surface of the box body 110. In this embodiment, the arrangement of the grooves 1121 and the protrusions 1122 is not limited in the direction of the horizontal splicing of the two box bodies 110, and it should be understood by those skilled in the art that, in order to better align the grooves 1121 of one box body 110 with the protrusions 1122 of another box body 110 when the two box bodies 110 are spliced, the grooves 1121 and the protrusions 1122 in the box body 110 are preferably arranged in a rectangular shape. As shown in FIGS. 15 to 19, the connecting pieces 112 and the screws 113 form the grooves 1121 and the protrusions 1122 on one side of the box body 110, and form the protrusions 1122 and the grooves 1121 on the corresponding positions on the other side of the box body 110; the grooves 1121 and the protrusions 1122 on one side of one box body 110 can be matched with the grooves 1121 and the protrusions 1122 on any side of another box body 110, that is, one box body 110 can be spliced with another box body 110 in the horizontal direction by contacting any one of the two side surfaces of the other box body 110 on which the grooves 1121 and the protrusions 1122 are arranged.

[0136] In some embodiments, as shown in FIG. 20, the connecting piece 112 is further provided with a cavity 1125 configured to accommodate the magnet 120, and the magnet 120 arranged in the cavity 1125 extends in the axial direction along the upper surface of the connecting piece 112 to the lower surface of the connecting piece 112, that is, one end of the magnet 120 has a magnetic force on the upper surface of the connecting piece 112, and the other end of the magnet 120 has a magnetic force on the lower surface of the connecting piece 112. In other embodiments, when the magnet 120 is directly bonded to the connecting piece 112, the cavity 1125 can not be arranged on the connecting piece 112.

[0137] Optionally, the cavity 1125 of the connecting piece 112 has an opening through which the magnet 120 can be inserted into the cavity 1125. Optionally, an adhesive layer can be formed between the magnet 120 and the inner wall of the cavity 1125 to reduce the possibility of the magnet 120 falling off.

[0138] Optionally, in some embodiments, the connecting piece 112 has an upper protrusion 1123 and a lower protrusion 1124, the end surface of the upper protrusion 1123 is the upper surface of the connecting piece 112, and the end surface of the lower protrusion 1124 is the lower surface of the connecting piece 112. One end of the cavity 1125 penetrates the upper protrusion 1123 to form an opening configured to pass the magnet 120, and the other end is located in the lower protrusion 1124. As can be seen from Figure 20, since the end surface of the upper protrusion 1123 is the upper surface of the connecting piece 112, and the end surface of the lower protrusion 1124 is the lower surface of the connecting piece 112, the solid structure of the connecting piece 112 at other positions is located between the upper surface and the lower surface, so that the volume of the connecting piece 112 is smaller, and therefore, the material consumption is less, and the material can be saved. Of course, in other embodiments, the connecting piece 112 can also be a structure without protrusion 1122 structure.

[0139] Optionally, in order to make the two boxes 110 have a larger attractive force when stacked vertically, the distance between one end of the magnet 120 and the upper surface of the connecting piece 112 is 0-2 mm, and the distance between the other end of the magnet 120 and the lower surface is 0-2 mm, so that the upper surface and the lower surface of the connecting piece 112 both have a larger magnetic force.

[0140] In some embodiments, the end surface of the upper protrusion 1123 is flush with one surface of the box body 111, and the end surface of the lower protrusion 1124 is flush with another surface of the box body 111. It can be understood that, that is, the upper surface of the connecting piece 112 is flush with the upper surface of the box body 111, and the lower surface of the connecting piece 112 is flush with the lower surface of the box body 111. Therefore, as shown in Figure 11, in the case where the upper surface of one box 110 and the upper surface of another box 110 are in contact with each other and connected by magnetic force, there is almost no gap between the upper surfaces of the two boxes 110, and the two boxes 110 can be better attached.
