[0035] As shown in Figures 1, 2 and 5, an embodiment of the present application provides a docking mechanism, including a base 1, a tray 2, a support frame 3 and a drive assembly 4; the drive assembly 4 includes a driving member (not shown in the figure), a transmission member 41 and a driving wheel 42 and a driven wheel 43 that are both rotatably mounted on the support frame 3, the driving member is mounted on the support frame 3 and connected to the driving wheel 42, and the transmission member 41 is sleeved on the driving wheel 42 and the driven wheel 43; it can be understood that the transmission member 41 includes but is not limited to belts, wire ropes, chains, etc.; the driving member includes but is not limited to motors, etc.; preferably, the driving wheel 42, the driven wheel 43 and the transmission member 41 constitute a synchronous wheel and synchronous belt mechanism.

[0036] The support frame 3 is slidably mounted on the base 1 and connected to the transmission member 41, and the tray 2 is slidably mounted on the support frame 3 and connected to the transmission member 41; the driving assembly 4 is used to drive the support frame 3 and the tray 2 to move, and the moving speed of the tray 2 is N times the moving speed of the support frame 3 (for example, 2≤N≥5), N is a positive integer greater than or equal to 2 (for example, N is 2, 3, 4, etc.), N is a positive integer greater than or equal to 2 (for example, N is 2, 3, 4, etc.). It can be understood that the tray 2 is connected to the transmission member 41 above the driving wheel 42 and the driven wheel 43, and the base 1 is connected to the transmission member 41 below the driving wheel 42 and the driven wheel 43; in unit time, the moving stroke of the tray 2 is twice the moving stroke of the support frame 3.

[0037] In this application, the driving assembly 4 includes a driving member, a driving wheel 42 and a driven wheel 43 both rotatably mounted on the support frame 3, and a transmission member 41 sleeved on the driving wheel 42 and the driven wheel 43. The driving member is mounted on the support frame 3 and connected to the driving wheel 42; the support frame 3 The tray 2 is slidably mounted on the base 1 and connected to the transmission member 41. The tray 2 is slidably mounted on the support frame 3 and connected to the transmission member 41. Thus, the transmission member 41, the tray 2, and the support frame 3 are similar to a movable pulley mechanism. During the process of the driving component 4 driving the tray 2 and the support frame 3 to move, the moving speed of the tray 2 is an integer multiple (for example, twice) of the moving speed of the support frame 3, and the moving stroke of the tray 2 is an integer multiple (for example, twice) of the moving stroke of the support frame 3. The tray 2 has a large moving stroke, so that the tray 2 can be extended to the outside of the docking cabinet or retracted into the inside of the docking cabinet. The user does not need to reach into the docking cabinet to pick up and place the items to be docked from the tray 2, which improves the convenience of the user in picking up and placing the items to be docked from the tray 2. In addition, installing the driving component 4 on the support frame 3 improves the compactness of the docking mechanism.

[0038] In one embodiment, as shown in Figures 6 to 8, the docking mechanism further includes a limiting assembly 5 and a limiting block 6 mounted on the base 1. It is understood that the limiting block 6 is mounted on the side of the base 1. Preferably, the limiting block 6 is provided with an inclined surface so that the first roller 53 can move along the inclined surface.

[0039] The limiting assembly 5 includes a torsional elastic member 51, a limiting frame 52 and a first roller 53 rotatably mounted on the limiting frame 52. The limiting frame 52 is rotatably mounted on the tray 2. The torsional elastic member 51 is mounted on the tray 2 and abuts against the limiting frame 52. It can be understood that the torsional elastic member 51 includes but is not limited to torsion, etc. When the limiting frame 52 is in an automatic state, the torsional elastic force of the torsional elastic member 51 will mobilize the limiting frame 52 to be in an upright state.

[0040] As shown in FIG7 , when the driving assembly 4 drives the supporting frame 3 and the tray 2 to be folded onto the base 1 , the first roller 53 moves onto the limiting block 6 and drives the limiting frame 52 to rotate until the end of the limiting frame 52 away from the first roller 53 is folded onto the tray 2 ;

[0041] Specifically, the driving assembly 4 drives the pallet 2 to be folded onto the support frame 3, and the support frame 3 is folded onto the base 1, and the first roller 53 will move to the limit block 6, so that the limit block 6 will drive the limit frame 52 to rotate and compress the torsional elastic member 51, and the end of the limit frame 52 away from the first roller 53 will be folded onto the pallet 2 (that is, the end of the limit frame 52 away from the first roller 53 will not be higher than the top surface of the pallet 2); therefore, when the pallet 2 is folded onto the base 1 (that is, the pallet 2 is folded into the docking cabinet), the limit frame 52 is folded onto the pallet 2, so that the limit frame 52 will not restrict the parts to be docked on the pallet 2 from moving out of the pallet 2.

[0042] As shown in Figure 8, when the driving component 4 drives the support frame 3 and the tray 2 to be in the extended state, the first roller 53 disengages from the limit block 6, and the torsional force of the torsional elastic member 51 drives the limit frame 52 to rotate until the end of the limit frame 52 away from the first roller 53 is erected and limited on the tray 2.

[0043] Specifically, the driving component 4 drives the pallet 2 to move out of the support frame 3, and the support frame 3 moves out of the base 1, the first roller 53 will move out of the limit block 6, so that the limit block 6 will release the restriction on the limit frame 52, and the torsional elastic force of the torsional elastic member 51 will drive the limit frame 52 to rotate until the end of the limit frame 52 away from the first roller 53 is erected on the pallet 2 (that is, the end of the limit frame 52 away from the first roller 53 is higher than the top surface of the pallet 2); therefore, when the pallet 2 extends out of the support frame 3 (that is, the pallet 2 extends out of the docking cabinet), that is, when the pallet 2 is folded on the base 1, the limit member is in an upright state, thereby avoiding the accident of the parts to be connected on the pallet 2 falling off.

[0044] Furthermore, a removal outlet 25 is provided on the pallet 2, and the limiting assembly 5 is arranged at the removal outlet 25; so that when the limiting frame 52 is erected and limited on the pallet 2 at one end away from the first roller 53, the limiting frame 52 in the erected state can limit the part to be connected from moving out of the pallet 2 from the removal outlet 25.

[0045] In one embodiment, as shown in Figure 6, the limiting assembly 5 includes a hinge 54, which includes a first hinge plate mounted on the tray 2 and a second hinge plate rotatably connected to the first hinge plate. The limiting frame 52 is mounted on the second hinge plate. The torsional elastic member 51 abuts the second hinge plate and is used to drive the limiting frame 52 to rotate via the second hinge plate. It can be understood that the limiting frame 52 is rotatably mounted on the tray 2 via the hinge 54, and the torsional elastic member 51 drives the limiting frame 52 to rotate via the hinge 54. In this embodiment, the design of the hinge 54 ensures the stability of the limiting frame 52 when rotatably mounted on the tray 2.

[0046] In one embodiment, the docking mechanism further includes a support plate 9 provided on the tray 2, and the first hinge plate is mounted on the support plate 9. It can be understood that the support plate 9 is provided with a sunken groove recessed toward the support frame 3, and the first hinge plate is fixed to the bottom wall of the sunken groove.

[0047] In one embodiment, as shown in Figures 2 and 6, the limiting assembly 5 further includes a second roller 55, which is rotatably mounted on an end of the limiting frame 52 away from the first roller 53. It is understood that the limiting frame 52 can drive the second roller 55 to stand upright on the pallet 2, or drive the second roller 55 to retract on the pallet 2; and when the limiting frame 52 drives the second roller 55 to retract on the pallet 2, the robot or the like drives the docking object to be docked out of the pallet 2, and the docking object can move on the second roller 55, thereby ensuring the stability of the docking object when it is removed from the pallet 2.

[0048] In one embodiment, as shown in FIG2 , the tray 2 includes a base plate 21 and a panel 22 disposed on the base plate 21. The space defined by the base plate 21 and the panel 22 forms a receiving slot 23 for receiving items to be connected. The tray 2 is provided with a removal opening 25 connected to the receiving slot 23. The limiting frame 52 is in an upright position and is used to prevent items to be connected in the receiving slot 23 from falling out of the removal opening 25. It is understood that the panel 22 is disposed on three sides of the base plate 21, with no panel 22 disposed on the side of the base plate 21 facing the removal opening 25. The limiting frame 52 is rotatably mounted on the base plate 21 and is located at the removal opening 25. In this embodiment, when the end of the limit frame 52 away from the first elastic member 72 is erected on the pallet 2, the limit frame 52 can play a role in blocking the removal outlet 25, so that the limit frame 52 and the enclosure 22 can limit the parts to be connected on the bottom plate 21, ensuring the stability of the pallet 2 driving the parts to be connected to move.

[0049] In one embodiment, as shown in Figures 2 to 4, the tray 2 is provided with a mounting groove 24 (recessed) facing the support frame 3; it can be understood that the mounting groove 24 can be set on the bottom wall of the accommodating groove 23, or on a connecting frame, and the connecting frame is installed on the lower surface of the tray 2.

[0050] The docking mechanism also includes a locking assembly 7, which includes an electromagnet 71, a first elastic member 72, and a guide rod 73. The guide rod 73 is slidably inserted into the mounting groove 24, and the electromagnet 71 is mounted on the guide rod 73. Alternatively, the guide rod 73 is mounted in the mounting groove 24, and the electromagnet 71 is slidably mounted on the guide rod 73. The first elastic member 72 is sleeved on the guide rod 73, and the opposite ends of the first elastic member 72 respectively abut against the electromagnet 71 and the bottom wall of the mounting groove 24. The electromagnet 71 is used to attract the docking object to the tray 2. It is understandable that the first elastic member 72 includes but is not limited to a spring. When the electromagnet 71 is in a free state, the electromagnet 71 protrudes above the tray 2. It should be noted that when the guide rod 73 is slidably inserted into the mounting groove 24 , the electromagnet 71 is fixed on the top of the guide rod 73 ; when the guide rod 73 is fixedly inserted into the mounting groove 24 , the electromagnet 71 is slidably installed on the guide rod 73 .

[0051] In this embodiment, when the electromagnet 71 is energized, it attracts the object to be docked, thereby adsorbing it onto the tray 2. When the electromagnet 71 is de-energized, it releases its attraction to the object to be docked, allowing it to be removed from the tray 2. The design of the electromagnet 71 ensures the stability of the object to be docked on the tray 2 and improves the convenience of removing the object from the tray 2. In addition, the electromagnet 71 can move up and down via the first elastic member 72, and the rebound force of the first elastic member 72 ensures that the electromagnet 71 is firmly adsorbed onto the object to be docked.

[0052] In one embodiment, the docking mechanism further includes a load cell (not shown) mounted on the support frame 3. The load cell is used to measure the weight of the pallet 2. Specifically, when the pallet 2 is collapsed onto the support frame 3, the pallet 2 is positioned above the load cell, which can weigh the pallet 2 and the docking component mounted on the pallet 2. In this embodiment, the design of the load cell enhances the automation level of the docking mechanism.

The second sensor is configured to detect labels on the docking pieces on the tray 2. It is understood that the second sensor includes, but is not limited to, a laser scanner, etc. The second sensor can identify labels on the docking pieces, further improving the automation level of the docking mechanism.

[0055] In one embodiment, the docking structure further includes a photoelectric switch (not shown in the figure) installed on the base 1 , and the photoelectric switch is used to control the starting position and the ending position of the support frame 3 moving on the base 1 .

In addition, the design of the first slide rail assembly 8 and the second slide rail assembly increases the load capacity of the tray 2.

[0057] Another embodiment of the present application further provides a docking cabinet, comprising a cabinet body and the aforementioned docking mechanism, wherein the docking mechanism is mounted within the cabinet body.
