[0082] Stacking is a good way to reduce space usage; however, simple stacking carries the risk of falling. Therefore, a stacking method that can both lock the stack and make it easy to unlock and retrieve items is needed.

[0083] In related technologies, stacking systems require manual unlocking while picking up stacked components. This operation is inconvenient and poses certain safety risks when the stacked components are heavy.

[0084] Please see Figures 1-43 To address the inconvenience of unlocking and retrieving stacked components in existing stacking systems, this application provides a stacking system 100, which can be used in storage, transportation, and other fields.

[0085] It should be noted that in the following embodiments, the X, Y and Z directions correspond to the three three-dimensional directions of the stacking system 100, but the X, Y and Z directions in this application are not limited to the forms shown in the embodiments.

[0086] Please continue reading. Figures 1-11The stacking system 100 provided in this application includes a first stacking device 10 and a second stacking device 20, which are stacked along the Z-direction. The first stacking device 10 has a first mating structure 30, and the second stacking device 20 has a second mating structure 40. The first mating structure 30 and the second mating structure 40 have a locked state and an unlocked state. In the locked state, the first mating structure 30 and the second mating structure 40 are locked to connect the first stacking device 10 and the second stacking device 20. In the unlocked state, the first mating structure 30 and the second mating structure 40 can be unlocked. The first mating structure 30 and the second mating structure 40 achieve unlocking and / or locking through magnetic force.

[0087] It is understood that by setting the first mating structure 30 and the second mating structure 40, this application can effectively connect the first stacking device 10 and the second stacking device 20 by utilizing the mating between the first mating structure 30 and the second mating structure 40, thereby improving the stability of the stacking system 100 during stacking, making full use of storage space, and ensuring transportation stability and safety after stacking.

[0088] In one embodiment, the positions of the first mating structure 30 and the second mating structure 40 in the locked state are defined as the locked positions, and their positions in the unlocked state are defined as the unlocked positions. The first mating structure 30 and the second mating structure 40 are positioned by magnetic force to achieve the unlocked and / or locked positions. When the first mating structure 30 and the second mating structure 40 are in the unlocked position, they are magnetically positioned so that the first stacking device 10 and the second stacking device 20 can be at least partially unlocked and separated. When the first stacking device 10 and the second stacking device 20 are separated, and the magnetic force between the first mating structure 30 and the second mating structure 40 decreases or disappears, at least one of the first mating structure 30 and the second mating structure 40 can return to the locked position. When the first stacking device 10 is stacked on top of the second stacking device 20 under its own weight or external pressure, the first mating structure 30 and the second mating structure 40 automatically lock. Thus, the overall cooperation of the first stacking device 10 and the second stacking device 20 is simpler, effectively improving operational efficiency.

[0089] The number of the first stacking device 10 and the second stacking device 20 can be set to one or more, and can be reasonably set according to actual needs. For example, this application describes the situation with the first stacking device 10 below and the second stacking device 20 above, and both the first stacking device 10 and the second stacking device 20 can be set as follows... Figure 1 and Figure 11 The rectangular box or box-shaped structure shown has the same dimensions and structure, but it can also be set to other shapes such as polygonal prisms or cylinders. Furthermore, the dimensions and structures of the first stacking device 10 and the second stacking device 20 can also be as shown... Figures 7-12 The settings shown are different. Specifically, when the sizes of the first stacking device 10 and the second stacking device 20 are different, the length of the first stacking device 10 can be set to an integer multiple of the length of the second stacking device 20 to facilitate matching.

[0090] To further improve the reliability of the stacking connection between the first stacking device 10 and the second stacking device 20, in one embodiment, such as Figure 2 , Figure 3 , Figure 9 , Figure 10 and Figure 11 As shown, the first stacking device 10 is further provided with a third mating structure 50, which is located on the side of the first stacking device 10 opposite to the first mating structure 30 along the Y or X direction. The second stacking device 20 is further provided with a fourth mating structure 60, which is located on the side of the second stacking device 20 opposite to the second mating structure 40 along the Y or X direction. The third mating structure 50 and the fourth mating structure 60 are mated together, and when the third mating structure 50 and the fourth mating structure 60 are mated, and the first mating structure 30 and the second mating structure 40 are mated, the movement of the first stacking device 10 and the second stacking device 20 is restricted at least along the Z direction.

[0091] It is understandable that the cooperation between the third cooperation structure 50 and the fourth cooperation structure 60, combined with the cooperation between the first cooperation structure 30 and the second cooperation structure 40, can ensure that the two ends of the first stacking device 10 and the second stacking device 20 can be connected, thereby restricting the movement of the first stacking device 10 and the second stacking device 20 at least in the Z direction.

[0092] Here, as Figure 3 As shown, the third mating structure 50 can adopt the same structure as the first mating structure 30, and the fourth mating structure 60 can adopt the same structure as the second mating structure 40. In this way, the mating between the third mating structure 50 and the fourth mating structure 60 is more robust, and can be adapted to the first stacking device 10 and the second stacking device 20, which have larger internal space and greater load-bearing capacity.

[0093] Of course, the third mating structure 50 and the fourth mating structure 60 can also adopt different structures, for example, such as Figure 10 and Figure 11As shown, one of the third mating structure 50 and the fourth mating structure 60 can be configured as a hook and the other as a slot. By inserting the hook into the slot, it engages with the first mating structure 30 and the second mating structure 40 to restrict the movement of the second stacking device 20 at least along the Z direction. This simplifies the engagement between the third mating structure 50 and the fourth mating structure 60, effectively improving the efficiency of locking or unlocking the first stacking device 10 and the second stacking device 20.

[0094] To further limit the movement of the first stacking device 10 relative to the second stacking device 20 along the X and Y directions, in one embodiment, as follows: Figure 8 and Figure 9 As shown, one of the first stacking device 10 and the second stacking device 20 protrudes along the Z direction to form a limiting protrusion 22, and the other is recessed along the Z direction to form a limiting groove 101. The limiting protrusion 22 is inserted into the limiting groove 101. In this way, the first stacking device 10 and the second stacking device 20 are more stable and reliable when stacked and locked.

[0095] Specifically, in this embodiment, the limiting protrusion 22 is disposed on the second stacking device 20, and the limiting groove 101 is formed on the first stacking device 10.

[0096] This application specifically illustrates the case where the third mating structure 50 and the first mating structure 30 have the same structure, and the fourth mating structure 60 and the second mating structure 40 have the same structure. Specifically, to achieve the stacking effect of the stacking system 100, the second mating structure 40 and the fourth mating structure 60 can be provided at the bottom of the second stacking device 20, and the first mating structure 30 and the third mating structure 50 can be provided at the top of the second stacking device 20.

[0097] In one embodiment, the first mating structure 30 includes a first mating member 31, and the second mating structure 40 includes a second mating member 41. The first mating member 31 and the second mating member 41 are mated by magnetic attraction or magnetic repulsion. Thus, different magnetic mating methods can be used to achieve locking and unlocking between the first mating structure 30 and the second mating structure 40.

[0098] Furthermore, in one embodiment, one of the first mating structure 30 and the second mating structure 40 is configured with a magnet, and the other is configured with a ferromagnetic material. That is, one of the first mating member 31 and the second mating member 41 is configured as a magnet, and the other is configured as a ferromagnetic material. In this way, magnetic attraction between the first mating member 31 and the second mating member 41 can be achieved.

[0099] It should be noted that a magnet is an object that can generate its own magnetic field. A ferromagnet, on the other hand, is an object that is ferromagnetic and can be attracted by a magnetic field. It is usually made of materials such as iron, cobalt, nickel, or alloys, or a single piece of polymer material containing these components, such as iron-plastic parts.

[0100] In another embodiment, magnets may also be configured in both the first mating structure 30 and the second mating structure 40. That is, both the first mating member 31 and the second mating member 41 are configured as magnets, so that magnetic attraction or magnetic repulsion can be achieved between the first mating member 31 and the second mating member 41.

[0101] In other embodiments, electromagnets may also be configured within the first mating structure 30 and / or the second mating structure 40. That is, the first mating member 31 and / or the second mating member 41 are configured as electromagnets, and magnetism is generated in the first mating member 31 and / or the second mating member 41 by energizing them, resulting in more flexible mating. Here, the example of both the first mating member 31 and the second mating member 41 being electromagnets will be used for explanation. Correspondingly, corresponding electrical components 70 are provided on the stacking system 100.

[0102] For example, energizing the first mating member 31 and the second mating member 41 can generate a magnetic attraction force. The strong magnetic interaction between the first mating member 31 and the second mating member 41 directly attracts the first mating structure 30 and the second mating structure 40, thereby achieving locking. When unlocking is required, de-energizing causes the magnetic attraction force to disappear, thus unlocking the device.

[0103] In one embodiment, the stacking system 100 further includes a control module 71, which is signal-connected to the first mating member 31 and is used to control the magnetic and non-magnetic states of the first mating member 31, and / or, the control module 71 is signal-connected to the second mating member 41 and is used to control the magnetic and non-magnetic states of the second mating member 41.

[0104] This facilitates the control of magnetic generation in the first mating part 31 and / or the second mating part 41.

[0105] Specifically, in this embodiment, the control module 71 includes a control switch 711. Of course, the control module 71 may also include an operation screen 712. Both of these configurations facilitate manual operation and greatly improve control convenience. The control switch 711 and the operation screen 712 can be reasonably arranged according to space requirements.

[0106] For example, such as Figure 5 As shown, a control switch 711 can be provided on the first mating structure 30 to control the magnetic and non-magnetic state of the first mating member 31, or, as... Figure 6 As shown, an operation screen 712 is provided on the first stacking device 10 to control the magnetic and non-magnetic states of the second mating member 41.

[0107] Furthermore, in one embodiment, as Figure 6 As shown, the stacking system 100 also includes a wireless communication module 72 and a remote operation module 73. The wireless communication module 72 is installed in the first stacking device 10 and / or the second stacking device 20, and is signal-connected to the control module 71 and the remote operation module 73, respectively. Thus, the stacking system 100 can be switched between locked and unlocked states via electronic remote control, further enhancing convenience.

[0108] Specifically, the wireless communication module 72 can be configured as wireless WiFi, Bluetooth, cellular network, satellite communication, NFC, mobile communication technology or long-range wireless broadcasting, etc., which will not be listed here.

[0109] In one embodiment, such as Figure 6 As shown, the stacking system 100 also includes a display module 74, which is used to indicate whether the stacking system 100 is in a locked or unlocked state. In this way, the locked and unlocked states of the stacking system 100 are more intuitive, thereby reducing the probability of operational errors and preventing damage to the first stacking device 10 and the second stacking device 20.

[0110] For example, the display module 74 can be configured as an indicator light, wherein red indicates that the stacking system 100 is in a locked state, and green indicates that the stacking system 100 is in an unlocked state. Of course, the light of the indicator light can also be set to other colors, as long as it can serve the same indication function.

[0111] This paper introduces a first embodiment of the mating of the first mating structure 30 and the second mating structure 40 of this application:

[0112] Please see Figure 3 and Figure 4 In one embodiment, the first mating structure 30 further includes a first movable member 32, which is movably connected to the first stacking device 10. The first mating member 31 is mounted on the first movable member 32. That is, in this embodiment, the first movable member 32 can drive the first mating member 31 to move, thereby achieving locking and unlocking between the first mating structure 30 and the second mating structure 40.

[0113] To further enhance convenience, in one embodiment, such as Figure 4As shown, the first mating structure 30 also includes a first elastic element 33, which is connected to the first movable element 32 and the first stacking device 10 respectively, so as to apply force to the first movable element 32. The elastic force of the first elastic element 33 can cooperate with the magnetic force of the first mating element 31 and the second mating element 41, as well as the external force, to lock or unlock the stacking device. For example, during the stacking process, when the second stacking device 20 is stacked on the first stacking device 10, it is only necessary to directly transport and place the second stacking device 20 on the first stacking device 10. At this time, the second stacking device 20 can automatically form a locked state by its own weight, reducing the cumbersomeness of the locking operation and effectively improving work efficiency and the convenience of stacking positioning. This application specifically describes the structure with the first elastic element 33. If the first elastic element 33 is not provided, the movement of the first movable element 32 can also be achieved directly by manual means.

[0114] Furthermore, in one embodiment, as Figure 5 and Figure 43 As shown, the first movable member 32 includes a base 321 and a first locking portion 322 disposed on the base 321. The base 321 is movably connected to the first stacking device 10. The second mating structure 40 includes a second locking portion 42 disposed on the second stacking device 20. The first locking portion 322 can be inserted into and engaged with the second locking portion 42 to form a locked state. In this way, the engagement of the first locking portion 322 and the second locking portion 42 is simple and can ensure the locking effect, thereby realizing the stacking limit between the first stacking device 10 and the second stacking device 20.

[0115] Specifically, the first locking part 322 can be configured as a locking plate, and the second locking part 42 can be provided with a corresponding locking groove. It can be understood that the locking plate and the locking groove can be configured one-to-one, or one locking groove can be used to engage with multiple locking plates. Here, the locking groove can be formed by directly slotting on the second locking part 42, or the second locking part 42 can be configured as a hook or other structure to utilize the space at the bend of the hook to form the locking groove.

[0116] The positions and engagement directions of the first locking part 322 and the second locking part 42 can be reasonably set according to the movement direction of the first movable member 32, which will be explained in detail below. It should also be noted that the engagement directions of the first mating structure 30 and the second mating structure 40 can be set opposite to the engagement directions of the third mating structure 50 and the fourth mating structure 60, which helps to prevent engagement failure.

[0117] Furthermore, in one embodiment, as Figure 4As shown, the first stacking device 10 has a movable slot 102, and the base 321 is movably installed in the movable slot 102. The movable slot 102 has two opposite side walls with second limiting portions 1021. Correspondingly, the first movable member 32 also includes a first limiting portion 326 connected to the opposite side walls of the base 321. The first limiting portion 326 can cooperate with the second limiting portion 1021 to limit the movement or rotation range of the first movable member 32 and prevent the first movable member 32 from disengaging from the movable slot 102.

[0118] Specifically, the second limiting part 1021 can be configured as a protruding structure protruding from the side wall of the movable groove 102, and the first limiting part 326 can be configured as an elastic snap-lock structure to facilitate the installation of the first movable part 32.

[0119] To facilitate the stacking of the first stacking device 10 and the second stacking device 20, the first movable member 32 can move automatically under the weight of the second stacking device 20. In one embodiment, such as... Figure 43 As shown, the first card part 322 is provided with a first guide slope 3221, which is located at one end of the first card part 322 near the second card part 42.

[0120] Furthermore, in one embodiment, as Figure 20 As shown, the second locking part 42 is provided with a second guide slope 421, which is located at one end of the second locking part 42 near the first locking part 322. Thus, when the second stacking device 20 is placed on the first stacking device 10, the engagement between the first locking part 322 and the second locking part 42 is smoother, thereby enabling rapid locking between the first stacking device 10 and the second stacking device 20.

[0121] To further improve the reliability of the card connection, in one embodiment, there are two first card portions 322, and the two first card portions 322 are spaced apart. Of course, the number of first card portions 322 can also be one or more, and can be reasonably set according to actual needs.

[0122] In one embodiment, such as Figure 43 As shown, the first movable member 32 also includes a first actuating part 323, which is connected to the base 321. The first actuating part 323 is used to provide a force application position to slide or rotate the first movable member 32. This makes it convenient for the user to apply force to pull or push the first movable member 32.

[0123] Specifically, the first actuating part 323 can be configured as any one of a protrusion, a groove, or knurling.

[0124] Furthermore, in one embodiment, two or all three of the base 321, the first card portion 322, and the first actuating portion 323 are configured as an integrally formed structure to facilitate processing and improve structural strength.

[0125] Please see Figures 12-23 In this embodiment, the second mating component 41 is installed on the second stacking device 20, and the first mating component 31 and the second mating component 41 are magnetically engaged. That is, the position between the second mating component 41 and the second stacking device 20 remains basically unchanged in this embodiment, so this embodiment requires external force to move the first movable component 32 to achieve unlocking.

[0126] Furthermore, such as Figures 12-23 As shown, the first movable member 32 is slidably connected to the first stacking device 10 along the Y direction. The first mating member 31 and the second mating member 41 are magnetically engaged along the Z direction. Here, the first mating member 31 and the second mating member 41 can be magnetically engaged in a locked state or in an unlocked state.

[0127] When the first mating member 31 and the second mating member 41 are magnetically engaged in the locked state, they can position the first mating structure 30 and the second mating structure 40 under the action of magnetic attraction. At this time, the first elastic member 33 deforms and maintains its shape under the action of magnetic attraction, and tends to move the first locking part 322 away from the second locking part 42. When unlocking is required, the first movable member 32 is moved by external force, causing the first mating member 31 and the second mating member 41 to be misaligned. The first elastic member 33 can then make the first movable member 32 move automatically, saving time and effort. Of course, an electromagnet can also be used to make the magnetic force of the first mating member 31 or the second mating member 41 disappear, and the first movable member 32 moves to achieve automatic unlocking.

[0128] When the first mating member 31 and the second mating member 41 are magnetically engaged in the unlocked state, in the locked state, the first mating member 31 and the second mating member 41 are misaligned, and there is insufficient magnetic attraction between them. Therefore, the first elastic member 33 can apply force to the first movable member 32, so that the first card portion 322 is inserted into the second card portion 42, achieving a snap-fit. When unlocking is required, the first movable member 32 can be moved to a certain position by external force, thereby achieving the attraction effect between the first mating member 31 and the second mating member 41 at the corresponding positions. At this time, the first elastic member 33 generates and maintains deformation under the action of magnetic attraction, and the first elastic member 33 has a tendency to drive the first card portion 322 towards the second card portion 42. At the same time, the first mating member 31 and the second mating member 41 can position the first mating structure 30 and the second mating structure 40 under the action of magnetic attraction, preventing the first movable member 32 from moving and resetting under the elastic force of the first elastic member 33, so that the first stacking device 10 and the second stacking device 20 are in an unlocked state. Therefore, in the unlocked state, there is no need to control the first movable part 32; stacking and disassembly can be achieved by directly picking up the second stacking part, making the operation simple. Furthermore, after disassembly, the magnetic attraction between the first mating part 31 and the second mating part 41 is lost due to the excessive distance, and the first movable part 32 can automatically reset under the elastic force of the first elastic part 33, making the overall operation even simpler.

[0129] Specifically, the first movable member 32 can slide along the Y direction toward or away from the center of the first stacking device 10, thereby unlocking the first card part 322 and the second card part 42.

[0130] For ease of explanation, this application will only use the magnetic attraction between the first mating part 31 and the second mating part 41 in the unlocked state as an example for illustration.

[0131] When the first movable member 32 moves the first locking part 322 away from the center of the first stacking device 10 under the action of external force, so as to release the engagement of the first locking part 322 and the second locking part 42 and form an unlocked state, that is, when the first movable member 32 is pulled outward by external force, the engagement direction of the first locking part 322 and the second locking part 42 needs to be set along the Y direction towards the center of the first stacking device 10. Based on this, as Figure 12 and Figure 13 As shown, the snap-fit ​​requirement can be achieved by connecting one end of the first snap-fit ​​part 322 to the base 321 and extending the other end toward the center of the first stacking device 10. It is understood that the position of the second snap-fit ​​part 42 corresponds to that of the first snap-fit ​​part 322, which will not be elaborated upon here.

[0132] Specifically, in this embodiment, the first locking portion 322 can be disposed on the side of the first mating member 31 away from the center of the first stacking device 10, and the first locking portion 322 extends from the side of the base 321 away from the center of the first stacking device 10 toward the direction closer to the center of the first stacking device 10. Since the first mating member 31 and the second mating member 41 are in a magnetically engaged state in the unlocked state, the first elastic member 33 is in a compressed state, and the first elastic member 33 is kept in a compressed state due to the magnetic attraction.

[0133] Similarly, in another embodiment, when the first movable member 32 moves the first locking part 322 towards the center of the first stacking device 10 under the action of an external force, so as to release the engagement of the first locking part 322 and the second locking part 42 and form an unlocked state, that is, when the first movable member 32 is pushed inward by an external force, the engagement direction of the first locking part 322 and the second locking part 42 needs to be set along the Y direction away from the center of the first stacking device 10. Based on this, as Figure 14 and Figure 15 As shown, the snap-fit ​​requirement can be achieved by connecting one end of the first snap-fit ​​part 322 to the base 321 and extending the other end in a direction away from the center of the first stacking device 10.

[0134] Specifically, in this embodiment, the first locking portion 322 can be disposed on the side of the first mating member 31 away from the center of the first stacking device 10, and the first locking portion 322 extends from the side of the base 321 away from the center of the first stacking device 10 toward the direction away from the center of the first stacking device 10. Since the first mating member 31 and the second mating member 41 are in a magnetically engaged state in the unlocked state, the first elastic member 33 is in a stretched state, and is kept in a stretched state due to the magnetic attraction. Here, the unlocking method is specifically described by pulling the first movable member 32.

[0135] In one embodiment, such as Figures 12-15 As shown, the base 321 has an assembly groove 3201, and the first mating member 31 is accommodated within the assembly groove 3201. This allows the first mating member 31 to be installed on the first movable member 32. The assembly groove 3201 can be located in the center of the base 321 or arranged symmetrically. Alternatively, the assembly groove 3201 can be located on the first locking portion 322, and one or more such grooves can be used.

[0136] In another embodiment, such as Figures 16-19As shown, the first movable member 32 also includes a positioning block 324. The base 321 has an assembly groove 3201. The positioning block 324 is installed in the assembly groove 3201 and is movably connected to the base 321. At least a portion of the positioning block 324 can protrude from the assembly groove 3201. At least a portion of the positioning block 324 forms a first mating member 31, or the first mating member 31 is installed on the positioning block 324. This allows the first mating member 31 and the second mating member 41 to engage in the unlocked state.

[0137] The movement of the positioning block 324 within the assembly slot 3201 can be as follows: Figure 16 and Figure 17 As shown, one end of the positioning block 324 is rotatably connected to the base 321. In this case, the positioning block 324 and the second mating part 41 are in line contact or surface contact. Alternatively, as... Figure 18 and Figure 19 As shown, the positioning block 324 is guided to move along the inner wall of the assembly groove 3201. At this time, the positioning block 324 and the second mating part 41 are in surface contact, which effectively ensures the contact area and improves the reliability of magnetic attraction. In this way, the positioning block 324 can move along the Z direction, thereby satisfying the mating positioning of the first mating part 31 and the second mating part 41.

[0138] Furthermore, such as Figures 16-19 As shown, the second mating structure 40 also includes a stop portion 43 disposed on the second stacking device 20, which can be disposed close to the second mating member 41. When the first mating member 31 and the second mating member 41 are magnetically attracted, the positioning block 324 is at least partially stopped by the stop portion 43, thereby restricting the movement of the first movable member 32 and thus positioning it. This prevents the first elastic member 33 from driving the first movable member 32 to move, making the positioning effect more reliable.

[0139] In one embodiment, such as Figure 43As shown, the first mating structure 30 also includes a gear 34, a transmission plate 35, and a third rotating shaft 36. The first mating component 31, gear 34, transmission plate 35, and third rotating shaft 36 are all mounted within the base 321. The first mating component 31 is connected to the periphery of the third rotating shaft 36 and can rotate around the axis of the third rotating shaft 36. The end of the third rotating shaft 36 away from the first mating component 31 is connected to the gear 34. One end of the transmission plate 35 is connected to the gear 34, and the other end at least partially extends out of the outer surface of the base 321. In the locked state, the first mating component 31 and the second mating component 41 are magnetically engaged. When unlocking is required, the transmission plate 35 can move under external force, driving the gear 34, the third rotating shaft 36, and the first mating component 31 to rotate, causing the first mating component 31 to rotate away from the second mating component 41. For example, the first mating part 31 can be rotated 90° or 180° to eliminate the magnetic attraction between the first mating part 31 and the second mating part 41, or to reduce the magnetic attraction to a certain extent, thereby avoiding affecting each other's movement.

[0140] That is, in this embodiment, when unlocking, the first mating part 31 is rotated by the transmission of gear 34, thereby weakening the magnetic attraction between the first mating part 31 and the second mating part 41, so as to release the engagement between the first mating structure 30 and the second mating structure 40.

[0141] Furthermore, in the locked state, the first elastic element 33 deforms, causing it to tend to move the first locking portion 322 away from the second locking portion 42. Thus, when the magnetic force between the first mating member 31 and the second mating member 41 is less than the elastic force of the first elastic element 33, the base 321 can automatically pop out, thereby releasing the latch and unlocking the first mating structure 30 and the second mating structure 40. Alternatively, the first elastic element 33 can be omitted, and unlocking can be achieved by manual pulling. Furthermore, depending on actual needs, the second mating structure 40 can also employ a gear 34 transmission method similar to that of the first mating structure 30 to achieve the rotation of the second mating member 41.

[0142] This paper introduces a second embodiment of the first mating structure 30 and the second mating structure 40 of this application:

[0143] The basic structure and concept of this embodiment are basically the same as those of the first embodiment, and the similarities will not be repeated. The difference lies in that, in this embodiment, as... Figures 20-23 As shown, the first movable member 32 is provided with a first rotating shaft 325, and the first movable member 32 is rotatably connected to the first stacking device 10 through the first rotating shaft 325. That is, the first movable member 32 in this embodiment is rotatably connected, so the movement of the first movable member 32 relative to the first stacking device 10 is relatively simple and quick.

[0144] Furthermore, the first elastic element 33 is configured as a torsion spring, and the first elastic element 33 is sleeved on the outer periphery of the first rotating shaft 325, and abuts against the first movable element 32 and the first stacking device 10 respectively, so as to apply force to the first movable element 32. In this way, when the first movable element 32 rotates under the action of external force, it will apply a force to the torsion spring, and the torsion spring will deform under the force. When the first movable element 32 rotates to a certain position, the first mating part 31 and the second mating part 41 are magnetically engaged and positioned. When the second stacking device 20 and the first stacking device 10 are disassembled, the magnetic attraction force that maintains the deformation of the torsion spring disappears, and the torsion spring can drive the first movable element 32 to automatically reset.

[0145] Similarly, in this embodiment, the first movable member 32 also has two rotation directions, namely, the first movable member 32 can rotate towards or away from the center of the first stacking device 10.

[0146] When the first movable member 32 moves the first locking part 322 towards the center of the first stacking device 10 under the action of external force, so as to release the engagement of the first locking part 322 and the second locking part 42 and form an unlocked state, that is, when the first movable member 32 is pushed upward and rotated by external force, the engagement direction of the first locking part 322 and the second locking part 42 needs to be set to approximately along the Y direction away from the center of the first stacking device 10. Based on this, as Figure 20 and Figure 21 As shown, the snap-fit ​​requirement can be achieved by connecting one end of the first snap-fit ​​part 322 to the base 321 and extending the other end in a direction away from the center of the first stacking device 10.

[0147] Specifically, in this embodiment, the first locking part 322 can be disposed on the side of the first mating member 31 away from the center of the first stacking device 10, and the first locking part 322 extends from the side of the base 321 away from the center of the first stacking device 10 toward the direction away from the center of the first stacking device 10.

[0148] Similarly, in another embodiment, when the first movable member 32 moves the first locking part 322 away from the center of the first stacking device 10 under the action of an external force, so as to release the engagement of the first locking part 322 and the second locking part 42 and form an unlocked state, that is, when the first movable member 32 is rotated downward by an external force, the engagement direction of the first locking part 322 and the second locking part 42 needs to be set to approximately along the Y direction towards the center of the first stacking device 10. Based on this, as Figure 22 and Figure 23 As shown, the snap-fit ​​requirement can be achieved by connecting one end of the first snap-fit ​​part 322 to the base 321 and extending the other end toward the center of the first stacking device 10.

[0149] Specifically, in this embodiment, the first locking part 322 can be disposed on the side of the first mating member 31 near the center of the first stacking device 10, and the first locking part 322 extends from the side of the base 321 near the center of the first stacking device 10 toward the direction near the center of the first stacking device 10.

[0150] Since the first elastic element 33 in this embodiment is a torsion spring, the structure and installation direction of the torsion spring can be adjusted so that after the first mating part 31 and the second mating part 41 are separated, the first elastic element 33 loses its magnetic constraint, thereby driving the first movable part 32 to rotate and reset.

[0151] This paper introduces a third embodiment of the first mating structure 30 and the second mating structure 40 of this application:

[0152] In this embodiment, the structure of the first movable member 32 is basically the same as that in the first embodiment, and the similarities will not be repeated. The difference is that, in this embodiment, as... Figures 24-33 As shown, the first mating member 31 is mounted on the first movable member 32, and the second mating structure 40 further includes a second movable member 44. The second mating member 41 is mounted on the second movable member 44, and the second movable member 44 is movably connected to the second stacking device 20. As the second movable member 44 moves, the second mating member 41 can magnetically engage with or be misaligned with the first mating member 31 to form a locked or unlocked state.

[0153] That is, in this embodiment, the magnetic engagement relationship between the first mating member 31 and the second mating member 41 is achieved by the two moving parts, thereby enabling the stacking system 100 to be locked or unlocked.

[0154] Furthermore, such as Figures 24-33 As shown, the first movable member 32 is slidably connected to the first stacking device 10, and the second movable member 44 is slidably connected to the second stacking device 20. The sliding direction of the first movable member 32 intersects the sliding direction of the second movable member 44. It can be understood that the intersecting sliding directions of the first movable member 32 and the second movable member 44 facilitate the engagement between the first mating member 31 and the second mating member 41. The sliding direction of the first movable member 32 can be perpendicular to the sliding direction of the second movable member 44, making sliding even simpler.

[0155] Specifically, the sliding direction of the first movable member 32 is approximately parallel to the Y direction, and the sliding direction of the second movable member 44 is set at an angle to the sliding direction of the first movable member 32, so as to facilitate the sliding of the second movable member 44.

[0156] Here, the first mating member 31 and the second mating member 41 can be magnetically attracted or magnetically repelled in the locked or unlocked state.

[0157] When the first mating member 31 and the second mating member 41 are magnetically engaged in the locked state, they can position the first mating structure 30 and the second mating structure 40 under the action of magnetic attraction. At this time, under the action of magnetic attraction, the first movable member 32 can move the first locking part 322 to engage with the second locking part 42. The first elastic member 33 deforms and maintains its shape under the action of magnetic attraction, and tends to move the first locking part 322 away from the second locking part 42. That is, the first movable member 32 overcomes the elastic force through magnetic attraction to achieve the engagement of the first locking part 322 and the second locking part 42. When unlocking is required, the second movable member 44 moves the second mating member 41 to a misaligned position with the first mating member 31 under the action of external force. The magnetic attraction between them gradually weakens. At this time, the first movable member 32 can move back to its original position under the elastic action of the first elastic member 33 to release the engagement of the first locking part 322 and the second locking part 42.

[0158] It is understandable that, since the first mating part 31 and the second mating part 41 are magnetically engaged, when the second mating part 41 moves away from the first mating part 31, the magnetic force weakens, and the first movable part 32 can automatically slide and position under the elastic force of the first elastic part 33 to form an unlocked state. Therefore, no external force is required to operate the first movable part 32, and the unlocking process is simpler.

[0159] Furthermore, the first elastic member 33 deforms due to magnetic force in the locked state. This deformation can be either compressive or tensile. Taking compressive deformation as an example, the first movable member 32 can be moved closer to or further away from the center of the first stacking device 10 by changing the connection end between the first stacking device 10 and the first elastic member 33.

[0160] For example, to move the first movable member 32 closer to the center of the first stacking device 10, one end of the first elastic member 33 away from the center of the first stacking device 10 can be connected to the first stacking device 10, and the other end of the first elastic member 33 can be connected to the first movable member 32. At this time, the engagement direction of the first locking part 322 and the second locking part 42 is changed accordingly. Specifically, one end of the first locking part 322 is connected to the base 321, and the other end extends away from the center of the first stacking device 10; that is, the first locking part 322 engages with the second locking part 42 in a direction away from the center of the first stacking device 10. Thus, when the first movable member 32 moves towards the center of the first stacking device 10 under external force, the second mating member 41 can move away from the first mating member 31 to release the engagement of the first locking part 322 and the second locking part 42, forming an unlocked state.

[0161] The first locking part 322 may be specifically located on the side of the first mating member 31 away from the center of the first stacking device 10, and the first locking part 322 extends from the side of the base 321 away from the center of the first stacking device 10 toward the direction away from the center of the first stacking device 10.

[0162] Furthermore, to move the first movable member 32 away from the center of the first stacking device 10, one end of the first elastic member 33 near the center of the first stacking device 10 can be connected to the first stacking device 10, and the other end of the first elastic member 33 can be connected to the first movable member 32. At this time, the engagement direction of the first locking part 322 and the second locking part 42 is changed accordingly. Specifically, one end of the first locking part 322 is connected to the base 321, and the other end extends towards the center of the first stacking device 10; that is, the first locking part 322 engages with the second locking part 42 towards the center of the first stacking device 10. Thus, when the first movable member 32 moves away from the center of the first stacking device 10 under external force, the second mating member 41 can move away from the first mating member 31 to release the engagement of the first locking part 322 and the second locking part 42, forming an unlocked state.

[0163] The first locking part 322 may be specifically located on the side of the first mating member 31 away from the center of the first stacking device 10, and the first locking part 322 extends from the side of the base 321 away from the center of the first stacking device 10 toward the direction closer to the center of the first stacking device 10.

[0164] When the first elastic member 33 is in a locked state and undergoes tensile deformation, it is only necessary to change the ends of the first stacking device 10 and the first movable member 32 that are connected to the first elastic member 33 accordingly, which will not be elaborated here.

[0165] When the first mating member 31 and the second mating member 41 are magnetically engaged in the unlocked state, in the locked state, the first mating member 31 and the second mating member 41 are misaligned, and there is insufficient magnetic attraction between them. Therefore, the first elastic member 33 can apply force to the first movable member 32, so that the first locking part 322 is inserted into the second locking part 42, achieving a locking connection. When unlocking is required, the second movable member 44, under the action of external force, drives the second mating member 41 to move closer to the first mating member 31, and the magnetic attraction between them gradually increases. At this time, the magnetic attraction overcomes the elastic force of the first elastic member 33, causing the first movable member 32 to move, thereby releasing the locking connection between the first locking part 322 and the second locking part 42. Furthermore, in the unlocked state, the first mating member 31 and the second mating member 41 can position the first mating structure 30 and the second mating structure 40 under the action of magnetic attraction. At this time, the first elastic member 33 generates and maintains deformation under the action of magnetic attraction, and the first elastic member 33 has a tendency to drive the first card portion 322 towards the second card portion 42. It can be understood that since the first mating member 31 and the second mating member 41 are magnetically engaged, when the second mating member 41 moves towards the first mating member 31, the magnetic attraction is strengthened, and the first movable member 32 can automatically slide and position under the action of magnetic force to form the unlocked state. Therefore, no external force is required to operate the first movable member 32, and the unlocking process is simpler.

[0166] Furthermore, in the magnetic attraction mode of the first mating member 31 and the second mating member 41 in the unlocked state, the connection method of the first elastic member 33 and the setting position of the first card part 322 are similar to those in the magnetic attraction mode in the locked state. Only the structure needs to be changed accordingly, which will not be explained in detail here.

[0167] When the first mating member 31 and the second mating member 41 are magnetically repelled in the locked state, they can position the first mating structure 30 and the second mating structure 40 under the action of magnetic repulsion. At this time, under the action of magnetic repulsion, the first movable member 32 can move the first locking part 322 to engage with the second locking part 42. The first elastic member 33 deforms and maintains its shape under the action of magnetic repulsion, and tends to move the first locking part 322 away from the second locking part 42. That is, the first movable member 32 overcomes the elastic force through magnetic repulsion to achieve the engagement of the first locking part 322 and the second locking part 42. When unlocking is required, the second movable member 44 moves the second mating member 41 to a misaligned position with the first mating member 31 under the action of external force. The magnetic repulsion between them gradually weakens. At this time, the first movable member 32 can move back to its original position under the elastic action of the first elastic member 33 to release the engagement of the first locking part 322 and the second locking part 42.

[0168] It is understandable that, since the first mating part 31 and the second mating part 41 are magnetically repelled, when the second mating part 41 moves away from the first mating part 31, the magnetic repulsion weakens, and the first movable part 32 can automatically slide and position under the action of magnetic force to form an unlocked state. Therefore, no external force is required to operate the first movable part 32, and the unlocking process is simpler.

[0169] Furthermore, in the magnetic repulsion engagement of the first mating member 31 and the second mating member 41 in the locked state, the connection method of the first elastic member 33 and the setting position of the first card part 322 are similar to those in the magnetic attraction engagement in the locked state. Only the structure needs to be changed accordingly, which will not be explained in detail here.

[0170] When the first mating member 31 and the second mating member 41 are magnetically repelled in the unlocked state, in the locked state, the first mating member 31 and the second mating member 41 are misaligned, and there is insufficient magnetic repulsion between them. Therefore, the first elastic member 33 can apply force to the first movable member 32, so that the first locking part 322 is inserted into the second locking part 42, achieving a locking connection. When unlocking is required, the second movable member 44, under the action of external force, drives the second mating member 41 to move closer to the first mating member 31. The magnetic repulsion between them gradually increases. At this time, the magnetic repulsion overcomes the elastic force of the first elastic member 33, causing the first movable member 32 to move, thereby releasing the locking connection between the first locking part 322 and the second locking part 42. Furthermore, in the unlocked state, the first mating member 31 and the second mating member 41 can position the first mating structure 30 and the second mating structure 40 under the action of magnetic repulsion. At this time, the first elastic member 33 generates and maintains deformation under the action of magnetic repulsion, and the first elastic member 33 has the tendency to drive the first card part 322 to move closer to the second card part 42.

[0171] It is understandable that, since the first mating part 31 and the second mating part 41 are magnetically repelled, when the second mating part 41 moves closer to the first mating part 31, the magnetic repulsion force is enhanced, and the first movable part 32 can automatically slide and position under the action of magnetic force to form an unlocked state. Therefore, no external force is required to operate the first movable part 32, and the unlocking process is simpler.

[0172] Furthermore, in the magnetic repulsion engagement of the first mating member 31 and the second mating member 41 in the unlocked state, the connection method of the first elastic member 33 and the setting position of the first card part 322 are similar to the magnetic attraction engagement in the locked state. Only the structure needs to be changed accordingly, which will not be explained in detail here.

[0173] The above describes the basic principle of the movement of the first mating structure 30 and the second mating structure 40 in this embodiment. Based on this, this embodiment also provides several embodiments based on this principle, as follows:

[0174] In one embodiment, such as Figures 24-31 As shown, the second stacking device 20 also has an assembly hole 21, and the second movable member 44 is movably installed in the assembly hole 21. The second movable member 44 can slide under the action of external force to switch the first mating member 31 and the second mating member 41 between mating and non-matting states.

[0175] For example, both the mounting hole 21 and the second movable member 44 can extend along the Z direction. Installing the second movable member 44 within the mounting hole 21 can improve the movement stability of the second movable member 44. The second mating member 41 is connected to the end of the second movable member 44 along the Z direction near the first movable member 32.

[0176] Furthermore, the sliding direction of the second movable member 44 is perpendicular to the sliding direction of the first movable member 32, and the second movable member 44 can slide under the action of external force pulling or pushing, so as to switch the first mating member 31 and the second mating member 41 in a mating and non-matting state. In this way, the sliding of the second movable member 44 is simpler.

[0177] The movement of the second movable component 44 can be coordinated with the movement of the second stacking device 20. When the operator's hand grips the second stacking device 20, the hand can contact the second movable component 44. This is especially true when force is applied to lift the device, or just before lifting. Figures 24-29 As shown, pulling the second movable part 44 causes it to slide upwards, unlocking the device and allowing the second stacking assembly 20 to be easily removed. Alternatively, the hand can press the second movable part 44 while applying force to remove it, such as... Figure 30 and Figure 31 As shown, the second movable part 44 slides down to unlock, thereby enabling the smooth extraction of the second stacking device 20.

[0178] Please continue reading. Figures 24-31 The second movable member 44 has a mounting hole 4401 on its side wall. The second mating structure 40 also includes a positioning component 45, which is installed in the mounting hole 4401 and at least partially protrudes from the mounting hole 4401 and engages with the inner wall of the assembly hole 21. This facilitates the positioning of the second movable member 44 and improves its reliability.

[0179] Specifically, the positioning assembly 45 includes a second elastic element 451 and a ball 452. One end of the ball 452 is connected to the second elastic element 451, and the other end protrudes at least partially from the mounting hole 4401 to engage with the inner wall of the assembly hole 21. Thus, the positioning assembly 45 has a simple structure and is easy to manufacture.

[0180] Furthermore, such as Figures 24-31As shown, the inner wall of the mounting hole 21 has a first mating position 211 and a second mating position 212. The first mating position 211 is located on the side of the second mating position 212 closer to the first movable member 32. The first mating position 211 and the second mating position 212 correspond to the locked state and the unlocked state, respectively. When the second movable member 44 moves the positioning component 45, the ball bearing 452 on the positioning component 45 can engage with the first mating position 211 or the second mating position 212, respectively, thereby providing tactile feedback to ensure that the second movable member 44 moves into place.

[0181] For example, when the second movable member 44 slides upward in the Z direction to unlock under the action of an external force, that is, when the second movable member 44 is pulled, the second movable member 44 can drive the positioning component 45 to move from the first mating position 211 to the second mating position 212. Wherein, as Figure 26 and Figure 27 As shown, the first mating part 31 and the second mating part 41 are magnetically engaged and attracted to each other in the locked state. By pulling the second movable part 44, the two parts move away from each other, weakening the magnetic attraction. The first movable part 32 then moves under the action of the first elastic member 33, thus unlocking the mechanism. Meanwhile... Figure 28 and Figure 29 In the process, the first mating part 31 and the second mating part 41 are magnetically repelled and misaligned in the locked state. When the second movable part 44 is pulled, the two parts move closer to each other, and the magnetic repulsion force is enhanced, thereby overcoming the elastic force of the first elastic part 33 and pushing the first movable part 32 to move to achieve unlocking.

[0182] When the second movable member 44 slides downward in the Z direction to unlock under the action of external force, that is, when the second movable member 44 is pressed, the second movable member 44 can drive the positioning component 45 to move from the second mating position 212 to the first mating position 211. For example, Figure 30 and Figure 31 As shown, the first mating part 31 and the second mating part 41 are magnetically repelled and misaligned in the locked state. Pressing the second movable part 44 causes them to move closer together, increasing the magnetic repulsion and overcoming the elastic force of the first elastic part 33, thus moving the first movable part 32 to unlock. Alternatively, the first mating part 31 and the second mating part 41 can be magnetically attracted and engaged in the locked state. Pressing the second movable part 44 causes them to move further apart, weakening the magnetic attraction, and the first movable part 32 moves under the action of the first elastic part 33 to unlock.

[0183] Specifically, the first mating position 211 and the second mating position 212 can be configured as a hole or groove structure that mates with the ball 452.

[0184] Please continue reading. Figures 26-31The second mating structure 40 also includes a third elastic element 46, which is connected to the end of the second movable member 44 away from the first movable member 32. The second movable member 44 can slide upwards or downwards along the Z direction under external force, and the third elastic element 46 can deform under external force, giving it a tendency to move and reset the second movable member 44. By providing the third elastic element 46, the second movable member 44 can automatically reset after the picking action is completed, eliminating the need for manual reset and further improving operational convenience.

[0185] In another embodiment, such as Figure 32 and Figure 33 As shown, the mounting hole 21 extends along the X direction, the second movable member 44 is configured as a shaft, and the second movable member 44 is movably connected to the second stacking device 20 and at least partially protrudes from the second stacking device 20. It is understood that moving the second mating member 41 via the shaft is also relatively simple. The second mating member 41 is connected to the periphery of the second movable member 44.

[0186] Furthermore, the second movable member 44 can slide inward or outward along the X direction under the action of external force, so as to switch the first mating member 31 and the second mating member 41 in a mating and non-matting state.

[0187] For example, the second movable member 44 can slide inward along the X direction under the action of an external force, that is, under the push of an external force, the second mating member 41 moves away from the first mating member 31, and the two change from a mating state to a non-matting state, thereby switching the locked state to an unlocked state. Of course, the second movable member 44 can also slide outward along the X direction under the action of an external force, that is, under the pull of an external force, the second mating member 41 moves away from the first mating member 31, and the two change from a mating state to a non-matting state, thereby switching the locked state to an unlocked state. It should be noted that this example specifically uses the magnetic attraction between the first mating member 31 and the second mating member 41, but when the two are magnetically repelled, only the pulling and pressing methods need to be changed accordingly.

[0188] Furthermore, such as Figure 24 , Figure 25 , Figure 32 and Figure 33 As shown, the first mating member 31 can be disposed on the side of the second mating member 41 along the Z direction. Of course, the first mating member 31 can also be as follows: Figures 26-31 As shown, it is located on the side of the second mating member 41 along the Y direction, so that the switching between the mating and non-matting states between the first mating member 31 and the second mating member 41 can be realized.

[0189] This paper introduces a fourth embodiment of the first mating structure 30 and the second mating structure 40 of this application:

[0190] The principle used in this embodiment is basically the same as that in the third embodiment, and the similarities will not be repeated. The difference is that, for example... Figures 34-42 As shown, in this embodiment, the second movable member 44 is rotatably connected to the second stacking device 20. The second movable member 44 can be configured as a shaft structure as in the third embodiment, wherein the second movable member 44 is threadedly connected to the second stacking device 20 and at least partially protrudes from the second stacking device 20. The axial direction of the second movable member 44 is perpendicular to the sliding direction of the first movable member 32.

[0191] That is, such as Figure 34 and Figure 35 As shown, when the second movable part 44 rotates, it can move axially through the thread, thereby driving the second mating part 41 to move closer to or further away from the first mating part 31. Specifically, it can be reasonably set according to the magnetic attraction or magnetic repulsion method, so as to realize the locking and unlocking of the stacking device.

[0192] Furthermore, the second movable element 44 in this embodiment and the third embodiment, as... Figures 32-35 As shown, a force-applying end 442 may be provided on the portion of the second movable member 44 that protrudes from the second stacking device 20. The force-applying end 442 is used to provide a force-applying position so that the operator can apply force to pull or push the second movable member 44.

[0193] However, this is not the only embodiment; in another embodiment, such as Figure 36 , Figure 37 , Figure 39 and Figure 40 As shown, the second movable member 44 can also be configured as a turntable, and the second movable member 44 is provided with a second rotating shaft 443, which allows the second movable member 44 to rotate around the axis of the second rotating shaft 443. The axial direction of the second rotating shaft 443 is the same as the sliding direction of the first movable member 32. The rotation of the turntable drives the second mating member 41 to rotate relative to the first mating member 31, which also facilitates the magnetic engagement between the two.

[0194] Furthermore, in the unlocked state, if the second mating part 41 and the first mating part 31 are positioned by magnetic attraction, then, in order to achieve automatic reset of the second movable part 44 after removal, as follows: Figure 39 and Figure 40 As shown, the second mating structure 40 also includes a fourth elastic element 47, which is configured as a torsion spring. The fourth elastic element 47 is sleeved on the outer periphery of the second rotating shaft 443 and is connected to the second movable element 44 and the second stacking device 20 respectively.

[0195] Please continue reading. Figures 36-42The second movable member 44 is provided with a second actuating part 441, which is used to provide a force application position to rotate the second movable member 44, thus facilitating the rotation of the second movable member 44.

[0196] Specifically, the second actuating part 441 can be configured as any one of a protrusion, a groove or knurling, which has a simple structure and is easy to process.

[0197] Furthermore, such as Figure 33 , Figure 34 , Figure 38 , Figure 41 and Figure 42 As shown, the first mating member 31 is located on the side of the second mating member 41 along the Y or Z direction. In this way, the first mating member 31 can rotate relative to the second mating member 41, thereby realizing the switching between mating and non-matting states.

[0198] It should be noted that the second movable part 44 can be configured as a shaft or a turntable.

[0199] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0200] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
