[0041] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0042] The embodiment of the present application provides a storage mechanism 100, such as Figure 1 As shown, the storage mechanism 100 includes a mounting frame 1, a first drawer 2, and a second drawer 3. The first drawer 2 is slidably mounted on the mounting frame 1 along a first direction X; the second drawer 3 is slidably mounted on the mounting frame 1 along the first direction X. The first drawer 2 and the second drawer 3 can be opened or closed by sliding relative to the mounting frame 1 along the first direction X. When the first drawer 2 and the second drawer 3 are closed, they are located within the mounting frame 1 to store goods. When the first drawer 2 and the second drawer 3 are opened, they at least partially extend from the mounting frame 1 to facilitate the retrieval and placement of goods. In the embodiment of the present application, the first direction X is a horizontal direction.

[0043] For the above-mentioned mounting frame 1, if Figure 1 As shown, the mounting frame 1 includes a support plate 11, a cover plate 12 and a support column 13. The support plate 11 and the cover plate 12 are spaced apart along the second direction Y, and the support plate 11 and the cover plate 12 are both perpendicular to the second direction Y. The two ends of the support column 13 are respectively connected to the edge of the support plate 11 and the edge of the cover plate 12, thereby forming a space between the support plate 11 and the cover plate 12 that can accommodate the first drawer 2 and the second drawer 3. The second direction Y is perpendicular to the first direction X. In the embodiment of the present application, the second direction Y is a vertical direction. Optionally, as Figure 1 As shown, the support plate 11 and the cover plate 12 are both rectangular, and arc chamfers are provided at the corners. Figure 1 As shown, there are multiple support columns 13, and the multiple support columns 13 are arranged at intervals to enhance the connection strength between the support plate 11 and the cover plate 12. Optionally, the support columns 13 are provided with slide rails 131, and the slide rails 131 extend along the first direction X. The first drawer 2 and the second drawer 3 are slidably connected to the support columns 13 via the slide rails 131, so as to be slidably arranged on the mounting frame 1 along the first direction X.

[0044] In the embodiment of the present application, when the second drawer 3 is closed, the opening of the second drawer 3 is positioned opposite the cover 12, thereby preventing the goods in the second drawer 3 from leaving the second drawer 3 and improving the safety of the goods in the second drawer 3. When the second drawer 3 is opened, the opening of the second drawer 3 is at least partially positioned opposite the cover 12, that is, when viewed along the second direction Y, the opening of the second drawer 3 is at least partially exposed, facilitating the removal of goods from the second drawer 3. The length of the cover 12 is greater than or equal to the length of the second drawer 3, and the width of the cover 12 is greater than or equal to the width of the second drawer 3, so that the cover 12 can cover the opening of the second drawer 3.

[0045] In the embodiment of the present application, when the first drawer 2 and the second drawer 3 are closed, the opening of the first drawer 2 is positioned opposite the bottom of the second drawer 3, thereby preventing the goods in the first drawer 2 from leaving the first drawer 2 and improving the safety of the goods in the first drawer 2. When the first drawer 2 is open and the second drawer 3 is closed, the opening of the first drawer 2 is at most partially positioned opposite the bottom of the second drawer 3. That is, when viewed along the second direction Y, the opening of the first drawer 2 is at least partially exposed, making it easier to take goods into and out of the first drawer 2.

[0046] For the first drawer 2, Figure 2 and Figure 3 As shown, the first drawer 2 is in the shape of a rectangular shell, and an opening is provided on the side of the first drawer 2 facing the second drawer 3. Figure 2 As shown, the opening of the first drawer 2 is arranged upward, that is, the top of the first drawer 2 is provided with an opening.

[0047] For the second drawer 3, as Figure 2 and Figure 3 As shown, the second drawer 3 is in the shape of a rectangular shell, and an opening is provided on the side of the second drawer 3 facing away from the first drawer 2. Figure 2 As shown, the opening of the second drawer 3 is arranged upward, that is, the top of the second drawer 3 is provided with an opening. The length of the second drawer 3 is equal to the length of the first drawer 2, and the width of the second drawer 3 is equal to the width of the first drawer 2. Therefore, when the first drawer 2 and the second drawer 3 are stacked, the second drawer 3 can cover the opening of the first drawer 2. It is understood that the length of the second drawer 3 can also be greater than the length of the first drawer 2, and the width of the second drawer 3 can also be greater than the width of the first drawer 2.

[0048] like Figures 3 to 5As shown, the second drawer 3 includes an annular wall 31 and a bottom plate 32. The bottom plate 32 is movably or removably disposed on the annular wall 31. The bottom plate 32 and the annular wall 31 together form the second drawer 3. For example, the annular wall 31 includes an opening and a through-hole 311 disposed opposite to each other. The bottom plate 32 is disposed at the through-hole 311 to cooperate with the annular wall 31 to enclose the second drawer 3. It is understood that the bottom plate 32 can be opened or closed. When the bottom plate 32 is closed, it means that the bottom plate 32 is located at the through-hole 311 and closes the through-hole 311. When the bottom plate 32 is open, it means that at least one end of the bottom plate 32 is away from the through-hole 311 and the through-hole 311 is open. Figure 3 The midsole plate 32 is in a closed state. Figure 4 and Figure 5 The midsole plate 32 is in an open state.

[0049] In the embodiments of this application, Figure 3 As shown, when the first drawer 2 and the second drawer 3 are stacked, the bottom plate 32 is positioned relative to the opening of the first drawer 2. That is, the through-hole 311 is positioned relative to the opening of the first drawer 2. In this case, by moving the bottom plate 32 away from the through-hole 311, the first drawer 2 and the second drawer 3 are connected, allowing the first and second drawers 2 and 3 to store goods together, such as large goods whose height is greater than both the first and second drawers 2 and 3. When large goods are no longer needed, the bottom plate 32 can be repositioned at the through-hole 311, allowing the first and second drawers 2 and 3 to store goods separately, increasing the amount of goods that can be stored. This allows for flexible control over whether the first and second drawers 2 and 3 store goods together, depending on the number of large goods. This not only meets the requirements for storing large goods but also increases the amount of goods that can be stored, thereby improving the space utilization of the storage structure 100. The connection between the first and second drawers 2 and 3 refers to the connection between the storage space within the first drawer 2 and the storage space within the second drawer 3, allowing the first and second drawers 2 and 3 to store goods together.

[0050] In some embodiments, the storage mechanism 100 includes multiple second drawers 3. When any two second drawers 3 are stacked, the bottom plate 32 of one second drawer 3 is positioned relative to the opening of another second drawer 3. Taking the arrangement of multiple second drawers 3 along the second direction Y as an example, any two adjacent second drawers 3 can be connected by moving the bottom plate 32 of the upper second drawer 3 away from the through-opening 311. Furthermore, since any two adjacent second drawers 3 can be connected, multiple adjacent second drawers 3 can also be connected, and multiple adjacent second drawers 3 and a first drawer 2 can also be connected, further improving the space utilization of the storage mechanism 100.

[0051] For the above-mentioned ring wall 31, Figures 3 to 5As shown, a support member 312 is provided on the side of the annular wall 31 adjacent to the first drawer 2. The support member 312 abuts against the side of the bottom plate 32 adjacent to the first drawer 2. The support member 312 provides support to the bottom plate 32 to support the goods in the second drawer 3. The support member 312 can extend in an annular shape along the inner surface of the annular wall 31 to abut against the edges of the bottom plate 32 and improve support stability. Alternatively, the support member 312 extends from the inner surface of the annular wall 31 toward the center of the annular wall 31. Optionally, the support member 312 defines a through-opening 311.

[0052] like Figures 3 to 5 As shown, the annular wall 31 is provided with a first magnetic member 313. When the bottom plate 32 is closed, the bottom plate 32 is magnetically connected to the first magnetic member 313. The first magnetic member 313 can be a magnet, and the bottom plate 32 can be, so that when the bottom plate 32 is close to the first magnetic member 313, the bottom plate 32 can be magnetically attracted to the first magnetic member 313 to limit the position of the bottom plate 32 relative to the annular wall 31 and limit the bottom plate 32 to a closed state, thereby improving the problem of the bottom plate 32 accidentally opening. Among them, the annular wall 31 is provided with a first mounting groove 314, and the first magnetic member 313 is set in the first mounting groove 314. The first mounting groove 314 can be set on the support member 312.

[0053] Ferromagnetic materials are substances that can produce significant magnetization in the presence of an external magnetic field. These materials have high magnetization, high saturation magnetization, high magnetic permeability, and are easily magnetized and demagnetized. Ferromagnetic materials typically include iron, cobalt, nickel, and their alloys, such as FeCrCo, FePt, SmCo, NdFeB, and Alnico.

[0054] like Figures 3 to 5 As shown, the annular wall 31 is provided with a second magnetic member 315. When the bottom plate 32 is opened, the bottom plate 32 is magnetically connected to the second magnetic member 315. The second magnetic member 315 can be a magnet, and the bottom plate 32 can be a ferromagnetic material, such as iron, cobalt or nickel, so that when the bottom plate 32 is close to the second magnetic member 315, the bottom plate 32 can be magnetically attracted to the second magnetic member 315 to limit the position of the bottom plate 32 relative to the annular wall 31 and limit the bottom plate 32 to an open state, thereby improving the problem of shaking and accidental closure of the bottom plate 32. Among them, the annular wall 31 is provided with a second mounting groove 316, and the second magnetic member 315 is arranged in the second mounting groove 316. The second mounting groove 316 can be located on the outer surface of the annular wall 31.

[0055] For the above-mentioned bottom plate 32, as Figures 3 to 5As shown, the bottom plate 32 is hinged to the annular wall 31 and can rotate relative to the annular wall 31. When the first drawer 2 and the second drawer 3 are stacked and the bottom plate 32 is open, the first drawer 2 and the second drawer 3 are connected. When the first drawer 2 and the second drawer 3 are stacked and the bottom plate 32 is closed, the first drawer 2 and the second drawer 3 can store goods separately. The bottom plate 32 can be hinged to the inner surface of the annular wall 31. When the bottom plate 32 is open, the bottom plate 32 can be in contact with the inner surface of the annular wall 31, thereby reducing the space occupied by the bottom plate 32 in the second drawer 3.

[0056] In some embodiments, as Figures 3 to 5 As shown, the bottom plate 32 includes a first plate 321 and a second plate 322, both of which are hinged to the annular wall 31. When the first drawer 2 and the second drawer 3 are stacked, the first plate 321 is disposed opposite a portion of the opening of the first drawer 2, and the second plate 322 is disposed opposite another portion of the opening of the first drawer 2. The first plate 321 and the second plate 322 can jointly open or close the through-opening 311 of the annular wall 31. Alternatively, only one of the first plate 321 and the second plate 322 can be opened, so that while the first drawer 2 and the second drawer 3 are connected, the second drawer 3 can also hold goods, thereby increasing the storage function of the storage mechanism 100.

[0057] In some embodiments, as Figures 3 to 5 As shown, the bottom plate 32 is provided with a third magnetic member 323. The third magnetic member 323 is a magnet or ferromagnetic material. When the third magnetic member 323 is a magnet, the first magnetic member 313 can be a ferromagnetic material. The third magnetic member 323 is used to magnetically connect with the first magnetic member 313 to limit the position of the bottom plate 32 relative to the annular wall 31. The bottom plate 32 is provided with a third mounting groove 324, and the third magnetic member 323 is disposed in the third mounting groove 324. It is understood that when the bottom plate 32 is closed, the third magnetic member 323 is disposed opposite the first magnetic member 313.

[0058] In some embodiments, as Figures 3 to 5 As shown, the bottom plate 32 is provided with a fourth magnetic member 325. The fourth magnetic member 325 is a magnet or ferromagnetic material. When the fourth magnetic member 325 is a magnet, the second magnetic member 315 can be a ferromagnetic material. The fourth magnetic member 325 is used to magnetically connect with the second magnetic member 315 to limit the position of the bottom plate 32 relative to the annular wall 31. The bottom plate 32 is provided with a fourth mounting groove 326, and the fourth magnetic member 325 is disposed in the fourth mounting groove 326. It is understood that when the bottom plate 32 is opened, the fourth magnetic member 325 is disposed opposite the second magnetic member 315.

[0059] In some embodiments, as Figure 3As shown, the first plate 321 and the second plate 322 can be relatively opened and closed; when viewed along the stacking direction of the first drawer 2 and the second drawer 3, that is, when viewed along the second direction Y, the first plate 321 and the second plate 322 at least partially overlap. This can reduce the gap between the first plate 321 and the second plate 322, and improve the problem of sheet-like goods in the second drawer 3 falling into the first drawer 2. Figure 6 As shown, the first plate 321 and the second plate 322 have equal thicknesses. A first overlapping portion 3211 is provided on the side of the first plate 321 facing the second plate 322, and a second overlapping portion 3221 is provided on the side of the second plate 322 facing the first plate 321. The thickness of the first overlapping portion 3211 is less than the thickness of the first plate 321, and the thickness of the second overlapping portion 3221 is less than the thickness of the second plate 322. The first plate 321 and the second plate 322 overlap via the first overlapping portion 3211 and the second overlapping portion 3221, thereby reducing the thickness of the first plate 321 and the second plate 322 at the intersection and improving the flatness of the first plate 321 and the second plate 322 when they overlap. Optionally, the sum of the thicknesses of the first overlapping portion 3211 and the second overlapping portion 3221 is equal to the thickness of the first plate 321.

[0060] In some embodiments, as Figure 1 As shown, the storage mechanism 100 also includes a plurality of drive assemblies 4, which are arranged on the mounting frame 1. Each drive assembly 4 is connected to a first drawer 2 or a second drawer 3 by transmission, and the drive assembly 4 is used to drive the first drawer 2 or the second drawer 3 to slide relative to the mounting frame 1 along the first direction X. The first drawer 2 and the second drawer 3 can be driven to open or close by the drive assembly 4, which is convenient for taking and placing goods, and the drive assembly 4 can also lock the first drawer 2 and the second drawer 3 without the need for additional locks. Each drive assembly 4 controls a first drawer 2 or a second drawer 3 separately. For the first drawer 2 and the second drawer 3 that are interconnected, the drive assembly 4 can drive them synchronously so that they are opened or closed synchronously, thereby improving the problem of damage to goods caused by the asynchronous opening or closing of the first drawer 2 and the second drawer 3 that are interconnected. Optionally, the drive assembly 4 is arranged on the support plate 11 or the cover plate 12. The driving assembly 4 arranged on the cover plate 12 is located on the side of the cover plate 12 away from the second drawer 3. The cover plate 12 is provided with a clearance hole 121, which extends along the first direction X. The driving assembly 4 is connected to the second drawer 3 through the clearance hole 121.

[0061] like Figure 7As shown, the drive assembly 4 includes a mounting base 41, a transmission wheel 42, a transmission belt 43, a connector 44, and a driver 45. The mounting base 41 is mounted on the support plate 11 or the cover plate 12, and the transmission wheel 42 is rotatably mounted on the mounting base 41 so as to rotatably mount the transmission wheel 42 on the mounting frame 1. There are at least two transmission wheels 42, and the transmission belt 43 is sleeved on at least two transmission wheels 42. One end of the connector 44 is connected to the transmission belt 43, and the other end of the connector 44 is connected to the first drawer 2 or the second drawer 3 to transmission-connect the transmission belt 43 to the first drawer 2 or the second drawer 3. The driver 45 is mounted on the mounting frame 1 and is transmission-connected to the transmission wheel 42. The driver 45 is configured to drive the transmission wheel 42 to rotate relative to the mounting frame 1 and drive the transmission belt 43 to move, thereby driving the first drawer 2 or the second drawer 3 to slide relative to the mounting frame 1 along the first direction X. At least two transmission wheels 42 are spaced apart along the first direction X. The portion of the transmission belt 43 located between the two transmission wheels 42 is connected to a connector 44, thereby driving the connector 44 to translate along the first direction X. The connector 44 of the drive assembly 4, disposed on the cover 12, is connected to the transmission belt 43 at one end and connected to the second drawer 3 at the other end through the clearance hole 121. Optionally, the driver 45 is a servo motor.

[0062] In some embodiments, the driver 45 is arranged on the mounting seat 41, and the transmission wheel 42 is arranged on the output shaft of the driver 45, so that the transmission wheel 42 is rotatably arranged on the mounting frame 1, and the driver 45 is connected to the transmission wheel 42 in a transmission manner, which is conducive to simplifying the structure of the drive component 4.

[0063] The present application also provides a robot (not shown) comprising a robot body and a storage mechanism 100 as described above, wherein the storage mechanism 100 is disposed on the robot body. The robot has the structural features and beneficial effects of the storage mechanism 100, which will not be described in detail here.

[0064] In the storage mechanism 100 and robot of the embodiment of the present application, the first drawer 2 and the second drawer 3 can be connected. The first drawer 2 and the second drawer 3 can store goods together or separately, thereby improving the space utilization of the storage mechanism 100. The number of second drawers 3 can be multiple, and multiple adjacent second drawers 3 can be connected. Multiple adjacent second drawers 3 can also be connected to one first drawer 2, further improving the space utilization of the storage mechanism 100. The first drawer 2 and the second drawer 3 are driven to open or close by the drive assembly 4 to facilitate the retrieval and placement of goods.
