[0058] The present invention provides a transfer device 100 .

[0059] Please refer to Figures 1 to 5 In some embodiments of the transfer device 100 of the present application, the transfer device 100 includes:

[0060] Rack 10;

[0061] a supporting bracket 20 slidably disposed on the frame 10 , with a fork channel 13 formed between the supporting bracket 20 and the frame 10 ;

[0062] a locking and releasing structure 30 , the locking and releasing structure 30 being provided on the frame 10 to lock the supporting bracket 20 with the frame 10 ; and

[0063] The fork assembly 40 is provided with a connecting structure 41, and the connecting structure 41 can enter and exit the fork channel 13. When the connecting structure 41 enters the fork channel 13, it is transmission-connected with the supporting bracket 20 to enable the supporting bracket 20 to disengage from the locking and releasing structure 30 and drive the supporting bracket 20 to slide.

[0064] The transfer device 100 proposed in the present application includes a frame 10 as a guide and bearing base and a supporting bracket 20 arranged on the frame 10 for supporting goods. The supporting bracket 20 is slidably arranged on the frame 10. The supporting bracket 20 and the frame 10 can be connected by a guide rail 11 slider mechanism, or the supporting bracket 20 can be connected by a roller 4331 and a guide rail 11 structure in the following embodiment, so that the supporting bracket 20 can slide on the frame 10 along a preset direction; in addition, a locking and releasing structure 30 is provided on the frame 10, and the locking and releasing structure 30 is used to lock the supporting bracket 20 on the frame 10 to prevent the supporting bracket 20 from sliding under the action of external force when the transfer device 100 is idle or needs to be positioned; wherein the locking and releasing structure 30 can be a magnetic attraction structure (which can be at least one of a permanent magnet attraction structure and an electromagnet attraction structure), a snap structure, a plug-in structure, a vacuum adsorption structure or a combination structure including at least two locking and releasing methods, which is not specifically limited here.

[0065] In addition, the support bracket 20 is placed on the frame 10, and a fork channel 13 is formed between the support bracket 20 and the frame 10, through which at least a portion of the fork assembly 40 can enter, thereby connecting the fork assembly 40 to the support bracket 20, so that the support bracket 20 can be pulled by the fork assembly 40 to slide on the frame 10. Specifically, a connecting structure 41 is provided at the front end of the fork assembly 40. When cargo needs to be transferred, the fork assembly 40 drives the connecting structure 41 into the fork channel 13. This can be done by moving the fork assembly 40 as a whole forward or backward to allow the connecting structure 41 to enter and exit the fork channel 13, or by using a telescopic structure 43 or the like to drive the connecting structure 41 to move in and out of the fork channel 13. The above is not limited to this. When the connecting structure 41 enters the fork channel 13, the connecting structure 41 is connected to the supporting bracket 20, thereby pulling the supporting bracket 20 to move. In the process of the connecting structure 41 being connected to the supporting bracket 20 and pulling the supporting bracket 20 to slide, the supporting bracket 20 is disengaged from the locking structure 30. The connection and release between the locking structure 30 and the supporting bracket 20 may be consistent with the sliding direction of the supporting bracket 20, for example, the locking is performed in the sliding direction of the supporting bracket 20, so that the contact locking relationship is reached when the supporting bracket 20 slides away from the locking structure 30; or when the magnetic structure is used for locking, the supporting bracket 20 slides away from the locking structure 30, causing the supporting bracket 20 and the locking structure to be released. The magnetic attraction between the release structure 30 decreases and the release structure 30 contacts and connects; of course, a trigger portion can also be provided on the connection structure 41, and the trigger portion acts on the release structure 30 to make the release structure 30 contact and lock the support bracket 20. For example, in the following embodiment, the driving member 411 can be used as a trigger portion to push the release structure 30 to release the plug-in fit between the support bracket 20 and the release structure 30, or the release structure 30 can adopt a structure such as an elastic protrusion. When the elastic protrusion protrudes, it can limit the support bracket 20. When the trigger portion presses down the elastic protrusion to make it retract, it can release the limit on the support structure. The locking and releasing method between the release structure 30 and the support bracket 20 is not specifically limited here. In addition, the connection method between the connection structure 41 and the support bracket 20 can adopt a magnetic attraction structure (which can be at least one of a permanent magnet attraction structure and an electromagnet attraction structure), a snap structure, a plug-in structure, or a combination structure including at least two connection methods, which is not limited here. The connecting structure 41 is allowed to enter and exit from the fork channel 13 below the supporting bracket 20 to connect to the supporting bracket 20, which can avoid collision between the connecting structure 41 and the goods above the supporting bracket 20 and cause damage, thereby improving the safety of the goods transfer process.

[0066] It should be noted that when the supporting bracket 20 is moved into place, a locking structure 30 can also be provided at the end position, so that when the fork assembly 40 is withdrawn, the supporting bracket 20 is locked by the locking structure 30 to prevent the supporting bracket 20 from sliding.

[0067] Therefore, it can be understood that in the transfer device 100 of the present invention, a combined structure of the frame 10 and the supporting bracket 20 is used to carry and transport goods. The supporting bracket 20 is slidably arranged on the frame 10 and can be used to place goods. When there is no need to transfer goods, the supporting bracket 20 is locked with the frame 10 by the locking and releasing structure 30 provided on the frame 10 to prevent the supporting bracket 20 from sliding under the action of external force, thereby improving the safety of the transfer device 100 when it is idle or only carrying goods; when it is necessary to transfer goods, the fork assembly 30 is locked. The connecting structure 41 of the component 40 enters the fork channel 13 and is connected to the supporting bracket 20, so that the supporting bracket 20 is disengaged from the lock-release structure 30. At this time, the fork assembly 40 can drive the supporting bracket 20 to slide on the frame 10. With this arrangement, the fork assembly 40 only needs to overcome the friction of the support during the transfer process, and the weight of the supporting bracket 20 and the cargo does not produce a vertical pressure effect on the fork assembly 40, thereby reducing the risk of damage to the fork assembly 40 and improving the safety of the transfer device 100 during the transfer of cargo.

[0068] Please refer to Figure 5 and Figure 6 In some embodiments of the transfer device 100 of the present application, the supporting bracket 20 is provided with a connecting member 21, the connecting member 21 is located in the fork channel 13, and the connecting member 21 is provided with one of a latch 4111 and an insertion port 215;

[0069] The connecting structure 41 is provided with a driving mechanism 413 and a driving member 411. The driving member 411 is provided with one of a latch 4111 and an insertion port 215. The driving mechanism 413 can drive the driving member 411 to slide so that the latch 4111 moves in and out of the insertion port 215, so as to connect or separate the connecting structure 41 and the supporting bracket 20. The sliding direction of the driving member 411 is perpendicular to the sliding direction of the supporting bracket 20.

[0070] In this embodiment, the supporting bracket 20 is provided with a connecting member 21. The connecting member 21 is provided at the bottom of the supporting bracket 20 and is located in the cargo fork channel 13. The connecting member 21 is used to connect with the connecting structure 41 so that the supporting bracket 20 can be pulled by the cargo fork assembly 40 and slide to realize the transfer of cargo. Specifically, the sliding direction of the supporting bracket 20 is defined as a first direction, and the horizontal plane has a second direction perpendicular to the first direction; the connecting structure includes a driving mechanism 413 and a driving member 411. The driving mechanism 413 can drive the driving member 411 to slide back and forth along the second direction. The driving mechanism 413 can be a cylinder pushing mechanism, a connecting rod transmission mechanism, a screw transmission mechanism or the transmission rod 4133 structure of the following embodiment, which is not limited here; at the same time, the driving member 411 and the connecting member 21 are respectively provided with a latch 4111 and an insertion port 215. The connecting member 21 can be provided with a protruding latch 4111, and the driving member 411 can be provided with an insertion port 215; or the driving member 411 can be provided with a plug 215. The moving member 411 is provided with a protruding pin 4111, and the connecting member 21 is provided with an insertion port 215. When the connecting structure 41 enters the fork channel 13, the driving member 411 and the connecting member 21 are arranged relative to each other, so that the pin 4111 and the insertion port 215 are arranged relative to each other. At this time, the driving member 411 is driven by the driving mechanism 413 to approach the connecting member 21 so that the pin 4111 is inserted into the insertion port 215, so that the connecting member 21 and the connecting structure 41 are connected and matched with each other using a plug-in structure, and in the sliding direction of the supporting bracket 20, the side walls of the pin 4111 and the insertion port 215 abut against each other, so that the supporting bracket 20 can be pulled by the fork assembly 40 and slide. When the supporting bracket 20 is moved into place, the driving mechanism 413 drives the driving member 411 to slide away from the connecting member 21, so that the pin 4111 disengages from the plug interface 215, thereby releasing the connection between the fork assembly 40 and the supporting bracket 20. At this time, the fork assembly 40 can be moved away alone to increase the operating space.

[0071] Please refer to Figure 16 In some embodiments of the transfer device 100 of the present application, the plug-in port 215 is formed by two mounting portions 216 arranged opposite to each other, and the two mounting portions 216 can be close to or far away from each other.

[0072] In this embodiment, two mounting portions 216 are provided on the connector 21 or the lock-release structure 30, and an insertion port 215 is formed between the two mounting portions 216. The two mounting portions 216 can be moved closer to or farther away from each other, so that the opening size of the insertion port 215 can be adjusted. At least one of the mounting portions 216 can be movable and adjustable. For example, the mounting hole for fixing the mounting portion 216 is a bar-shaped hole, or a plurality of mounting holes are provided, one of which is selected to fix the mounting portion 216. This makes the size of the insertion port 215 adjustable and can be used to cooperate with pins 4111 of different sizes.

[0073] Please refer to Figure 3In some embodiments of the transfer device 100 of the present application, the lock-release structure 30 and the connecting member 21 are relatively slidable, the connecting member 21 is provided with one of a positioning hole 217 and an inserting portion 37, and the lock-release structure 30 is provided with one of a positioning hole 217 and an inserting portion 37;

[0074] The driving member 411 can drive the locking and releasing structure 30 and the connecting member 21 to slide relative to each other, so that the plug-in portion 37 moves in and out of the positioning opening 217 to lock or release the supporting bracket 20 .

[0075] The locking mechanism 30 is configured to lock the support bracket 20 by locking the connecting member 21 of the support bracket 20, and the locking mechanism 30 and the support bracket 20 are plugged together using a plug-in structure, wherein the locking mechanism 30 and the connecting member 21 are respectively provided with a positioning hole 217 and a plug-in portion 37, and the positioning hole 217 can be provided on the locking mechanism 30 and the plug-in portion 37 can be protruded on the connecting member 21, or the plug-in portion 37 can be provided on the locking mechanism 30 and the positioning hole 217 can be provided on the connecting member 21. This is not limited here, and only the plug-in portion 37 can enter and exit the positioning hole 217 along the second direction. In addition, in this embodiment, the locking mechanism 30 and the connecting member 21 can slide relative to each other in the second direction. The connecting member 21 can be slidably provided at the bottom of the support bracket 20, or the locking mechanism 30 can be slidably provided on the frame 10. When the connecting member 21 is slidable, it can be understood that in the technical solution of the aforementioned embodiment, the driving member 411 and the connecting member 21 When the locking structure 30 is slidable, the driving member 411 can directly push the connecting member 21 to make the connecting member 21 slide relative to the locking structure 30; when the locking structure 30 is slidable, the driving member 411 can slide to insert the latch 4111 into the plug-in port 215, and the driving member 411 can simultaneously push the locking structure 30 to slide so that the plug-in portion 37 slides out of the positioning port 217, or the driving member 411 can first push the locking structure 30 to slide so that the plug-in portion 37 slides out of the positioning port 217. After locking the supporting bracket 20, the driving member 411 continues to move forward to insert the pin 4111 into the plug-in port 215; the connecting member 21 can also be made slidable. At this time, after the driving member 411 slides to insert the pin 4111 into the plug-in port 215, the driving member 411 continues to move forward to push the locking structure 30 to slide so that the plug-in portion 37 slides out of the positioning port 217. The specific matching structure of the locking structure 30, the driving member 411 and the connecting member 21 is not limited here.

[0076] When the supporting bracket 20 is moved into position and another locking and releasing structure 30 is provided at the end position, the driving mechanism 413 drives the driving member 411 to slide away from the connecting member 21, so that the latch 4111 disengages from the plug-in port 215, thereby releasing the connection between the fork assembly 40 and the supporting bracket 20. At this time, the driving member 411 can make the connecting member 21 and the locking and releasing structure 30 at the end position plug and mate to lock the supporting bracket 20 at the end position.

[0077] Please refer to Figure 7 In some embodiments of the transfer device 100 of the present application, the locking structure 30 is slidably provided on the frame 10, the sliding direction of the locking structure 30 is perpendicular to the sliding direction of the supporting bracket 20, and the driving mechanism 413 drives the driving member 411 to drive the locking structure 30 to slide.

[0078] The technical solution of the aforementioned embodiment enables the connecting member 21 and the lock-release structure 30 to slide relative to each other so that the connecting member 21 and the lock-release structure 30 are connected or separated; at the same time, the connecting member 21 needs to be used to connect with the connecting structure 41 so that the supporting bracket 20 can be pulled by the fork assembly 40 and slide on the frame 10 to realize cargo transfer. In this embodiment, the locking structure 30 is slidably provided on the frame 10, so that the connecting member 21 is fixed to the bottom of the supporting bracket 20. At this time, the driving member 411 pushes the locking structure 30 to slide during the process of sliding and plugging with the connecting member 21 so that the locking structure 30 releases the lock on the connecting member 21; it can be understood that if the connecting member 21 is slidable, and the fork assembly 40 abuts against the connecting member 21 to pull the supporting bracket 20 to move, it is easy to cause the sliding connection structure 41 of the connecting member 21 to be overstressed and damaged, affecting the performance stability and safety of the transfer device 100; the connecting member 21 is fixed, and locking and releasing are achieved by sliding the locking structure 30. At this time, the connection strength between the connecting member 21 and the main body of the supporting bracket 20 is high, the structural stability is strong, and it is not easy to be damaged. The transfer process is more stable and safer.

[0083] The driving member 411 is provided with a pushing portion 4115, which can enter and exit the connecting channel 39. When the connecting structure 41 enters the fork channel 13, the pushing portion 4115 enters the connecting channel 39, so that the driving mechanism 413 can drive the pushing portion 4115 to drive the lock release structure 30 to slide.

[0084] In this embodiment, the locking and releasing structure 30 includes a support member 31 as a bearing base, and the support member 31 is slidably connected to the frame 10. Two guide portions arranged opposite to each other can be provided on the frame 10, so that the two side edges of the support member 31 can be slidably inserted into the two guide portions, or the support member 31 and the frame 10 can be connected through a guide rail 11 slider mechanism, which is not limited here; a locking and releasing portion 33 and a connecting portion 35 are convexly provided on the support member 31, and the locking and releasing portion 33 is used to cooperate with the connecting member 21, and one of the plug-in portion 37 and the positioning port 217 is provided on the locking and releasing portion 33, and the connecting portion 35 is used to cooperate with the driving member 411 so that the driving member 411 can pull the locking and releasing structure 30 to slide; specifically, the connecting member 31 A connecting channel 39 is provided on the connecting portion 35, and the connecting channel 39 extends and passes through in the first direction. A pushing portion 4115 is provided on the driving member 411 of the connecting structure 41. When the connecting structure 41 moves forward or backward, the pushing portion 4115 enters and exits the connecting channel 39 to connect or separate the driving member 411 and the lock-release structure 30. When the pushing portion 4115 is located in the connecting channel 39, the driving mechanism 413 can drive the driving member 411 to slide to drive the lock-release structure 30 to slide; when the fork assembly 40 pulls the supporting bracket 20 to slide or retract out of the fork channel 13, the pushing portion 4115 can exit the connecting channel 39 from one end opening of the connecting channel 39, so as not to interfere with the lock-release structure 30.

[0085] Please refer to Figures 5 to 8 In some embodiments of the transfer device 100 of the present application, the lock-release portion 33 and the connecting portion 35 are respectively provided on two sides of the support member 31 spaced apart along the sliding direction of the lock-release structure 30 ;

[0086] The connecting member 21 includes a positioning portion 211 and a fixing portion 213 spaced apart along the sliding direction of the lock-release structure 30. The positioning portion 211 is located on a side of the connecting portion 35 away from the connecting structure 41. The positioning portion 211 is provided with one of a positioning opening 217 and a plug-in portion 37. The fixing portion 213 is provided with one of a latch 4111 and a plug-in opening 215. The fixing portion 213 is arranged higher than the connecting portion 35.

[0087] The pushing portion 4115 is disposed at the bottom of the driving member 411 , and the latch 4111 or the plug port 215 is disposed at an end of the driving member 411 facing the connecting member 21 .

[0088] In this embodiment, the release portion 33 and the connecting portion 35 are spaced apart along the second direction, and the connecting portion 35 is arranged near the middle of the fork channel 13. At the same time, a positioning portion 211 and a fixing portion 213 spaced apart along the second direction are provided on the connecting member 21. The positioning portion 211 is arranged opposite to the release portion 33. The positioning portion 211 and the release portion 33 are respectively provided with a positioning port 217 and a plug-in portion 37 for connecting the release structure 30 and the connecting member 21. The fixing portion 213 is provided with one of a latch 4111 and a plug-in port 215 for connecting with the driving member 411. The latch 4111 is provided at the end of the driving member 411, and the pushing portion 4115 is provided at the bottom of the driving member 411, so that the fixing portion 213 is higher than the connecting channel 39. In this way, In the initial state, the locking structure 30 and the connecting member 21 are connected through the plug-in relationship between the plug-in portion 37 and the positioning port 217 to lock the supporting bracket 20. When the driving member 411 enters the fork channel 13 along the connecting structure 41, the fixing portion 213 and the driving member 411 are spaced apart in the second direction and are located above the connecting portion 35, and the pushing portion 4115 can directly enter the connecting channel 39. Then the driving member 411 slides toward the side of the connecting member 21 so that the pin 4111 is inserted into the plug-in port 215. At the same time, the pushing portion 4115 pushes the locking structure 30 to slide so that the plug-in portion 37 withdraws from the positioning port 217, thereby making the separation of the supporting bracket 20 from the locking structure 30 and the connection of the fork assembly 40 to the supporting bracket 20 completed synchronously, thereby improving work efficiency.

[0089] Please refer to Figure 5 In some embodiments of the transfer device 100 of the present application, the pushing portion 4115 is provided with a guide wheel 4117. When the pushing portion 4115 enters and exits the connecting channel 39, the guide wheel 4117 rolls against the side wall of the connecting channel 39.

[0090] It will be appreciated that in the embodiment of the present application, the pushing portion 4115 enters and exits the connecting channel 39 to connect the driving member 411 with the lock-release structure 30, thereby driving the lock-release structure 30 to slide to lock and release the support bracket 20. At this time, the pushing portion 4115 will inevitably contact the sidewall of the connecting channel 39 during the process of entering and exiting the connecting channel 39. In this embodiment, the pushing portion 4115 is provided with a guide wheel 4117. The guide wheel 4117 is rotatable. When the pushing portion 4115 enters and exits the connecting channel 39, the guide wheel 4117 rolls along the sidewall of the connecting channel 39. This configuration reduces friction between the pushing portion 4115 and the connecting portion 35, preventing wear between the pushing portion 4115 and the connecting portion 35. Furthermore, during the rotation of the guide wheel 4117, the pushing portion 4115 is guided to accurately enter the connecting channel 39.

[0091] Please refer to Figure 8 In some embodiments of the transfer device 100 of the present application, the plug-in portion 37 is provided with a rolling member 38 , and when the plug-in portion 37 enters and exits the positioning port 217 , the rolling member 38 rolls against the side wall of the positioning port 217 .

[0092] It is understood that the locking mechanism 30 and the connector 21 of the present embodiment are connected by the plug-in fit of the plug-in portion 37 and the positioning opening 217. When the plug-in portion 37 is withdrawn from the positioning opening 217, the locking mechanism 30 locks the support bracket 20. At this time, the plug-in portion 37 may contact the side wall of the positioning opening 217 during the process of entering and exiting the positioning opening 217. In this embodiment, a rolling member 38 is provided on the plug-in portion 37. When the plug-in portion 37 enters and exits the positioning opening 217, the rolling member 38 can roll along the side wall of the positioning opening 217. This configuration can reduce friction between the plug-in portion 37 and the connector 21, preventing mutual wear between the plug-in portion 37 and the connector 21. In addition, during the rotation of the rolling member 38, it can also guide the plug-in portion 37 to accurately enter the positioning opening 217, thereby performing a positioning function.

[0093] Referring to the drawings, in some embodiments of the transfer device 100 of the present application, the positioning opening 217 is formed by enclosing two oppositely disposed limiting portions 218 , and the two limiting portions 218 can be moved closer to or farther away from each other.

[0094] In this embodiment, two limiting portions 218 are provided on the connecting member 21 or the locking and releasing structure 30, and a positioning opening 217 is formed between the two positioning portions 211, so that the two limiting portions 218 can be moved closer to or farther away from each other, that is, the opening size of the positioning opening 217 can be adjusted, and at least one of the limiting portions 218 can be movable and adjusted. For example, the mounting hole for fixing the limiting portion 218 is a strip hole, or a plurality of mounting holes are provided and one of them is selected to fix the limiting portion 218; the size of the positioning opening 217 is adjustable, and can be used to cooperate with plug-in portions 37 of different sizes, and the positioning accuracy of the supporting bracket 20 on the frame 10 can be adjusted according to the size of the positioning opening 217, thereby improving the flexibility of use.

[0095] Please refer to Figure 11 In some embodiments of the transfer device 100 of the present application, the connecting structure 41 further includes a base 415 and a guide mechanism 417 , wherein the guide mechanism 417 is provided between the base 415 and the driving member 411 to guide the sliding direction of the driving member 411 ;

[0096] The driving mechanism 413 includes a sliding member 4131 and a transmission rod 4133. The sliding member 4131 is slidably provided on the base 415. The sliding direction of the sliding member 4131 is consistent with the sliding direction of the supporting bracket 20. The two ends of the transmission rod 4133 are respectively hinged to the sliding member 4131 and the driving member 411 to drive the driving member 411 to slide when the sliding member 4131 slides.

[0097] In the technical solution of the aforementioned embodiment, a driving member 411 and a driving mechanism 413 are provided in the connecting structure 41, so that the driving mechanism 413 can drive the driving member 411 to slide along the second direction to connect or disconnect with the connecting member 21. Furthermore, in some embodiments, the locking and releasing structure 30 and the connecting member 21 can also be disconnected or connected at the same time. In this embodiment, the connecting structure 41 also includes a base 415 and a guide mechanism 417. The base 415 serves as the bearing base of the connecting structure 41 and can be used to carry the driving member 411 so that the driving member 411 slides on the base 415, and at the same time, the driving member 411 and the base 415 are slidably connected through the guide mechanism 417. The guide mechanism 417 can be two guide parts arranged opposite to each other on the base 415, so that the two side edges of the driving member 411 can be slidably inserted into the two guide parts respectively, or the driving member 411 and the base 415 can be connected through a guide rail 11 slider mechanism. No limitation is made here. The setting of the guide mechanism 417 can make the sliding process of the driving member 411 more stable, limit its sliding direction, and make the driving member 411 not easily deviated.

[0098] Furthermore, the driving structure includes a sliding member 4131 and a transmission rod 4133. The sliding member 4131 is slidably arranged on the base 415 and can be driven by a power member such as a driving motor or a cylinder, a hydraulic cylinder, etc., or at least one transmission mechanism such as a screw transmission mechanism, a gear 435 transmission mechanism, a belt transmission mechanism, etc. can be set between the power member and the sliding member 4131. For example, a driving motor is set, and a screw transmission mechanism is set between the driving motor and the sliding member 4131. The sliding member 4131 is connected to the screw nut. When the driving motor drives the screw to rotate, the screw nut drives the sliding member 4131 to slide, and the two ends of the transmission rod 4133 are respectively hinged to the driving member 411 and the sliding member 4131. At this time, the sliding member 4131 will synchronously drive the transmission rod 4133 to swing, thereby driving the driving member 411 to slide, and the driving member 411 and the base 415 have been limited by the guide mechanism 417. At this time, the process of the sliding member 4131 driving the driving member 411 to slide through the transmission rod 4133 is relatively stable.

[0099] In some embodiments, the supporting bracket 20 is provided with at least two connecting members 21, at least one connecting member 21 is provided on each side of the fork channel 13, and the connecting structure 41 is provided with at least two driving members 411, and each group of driving members 411 is arranged corresponding to a connecting member 21. At this time, two driving mechanisms 413 can be respectively provided, and two groups of power members and transmission mechanisms can be used to drive the driving mechanisms 413 and the driving members 411 to move; or one group of power members and transmission mechanisms can be provided to simultaneously drive the two driving mechanisms 413 and the driving members 411 to move. For example, a set of driving motors and screw transmission mechanisms is used, so that the sliding members 4131 of the two driving mechanisms 413 are fixed to the screw nuts of the screw transmission mechanism, so that the driving members 411 and the connecting members 21 on both sides are synchronously connected or separated.

[0100] Please refer to Figure 11 In some embodiments of the transfer device 100 of the present application, the driving member 411 is provided with a limiting groove 4119, and the side walls of the limiting groove 4119 are arranged at an angle. One end of the transmission rod 4133 is hinged between the side walls of the groove, and the groove side walls can be used to limit the rotation angle of the transmission rod 4133 relative to the driving member 411.

[0101] In this embodiment, a limiting groove 4119 is opened on the driving member 411, and the limiting groove 4119 has two groove side walls arranged opposite to each other, and one end of the transmission rod 4133 is hinged between the two groove side walls. At this time, when the sliding member 4131 slides and drives the transmission rod 4133 to rotate, the rotation angle of the transmission rod 4133 can be limited by the groove side wall, thereby limiting the sliding angle of the driving member 411 and preventing the driving member 411 from excessive extension or retraction.

[0102] Please refer to Figure 12In some embodiments of the transfer device 100 of the present application, the base 415 is provided with an avoidance opening 4151, the pushing portion 4115 is provided at the bottom of the driving member 411, and is passed through the avoidance opening 4151 to protrude from the base 415, and the pushing portion 4115 can slide in the avoidance opening 4151.

[0103] In the technical solution of the aforementioned embodiment, the driving member 411 is further provided with a pushing portion 4115 for cooperating with the connecting portion 35 of the lock release structure 30 to drive the lock release structure 30 to slide. In this embodiment, the pushing portion 4115 is disposed at the bottom of the driving member 411, and a clearance opening 4151 for the pushing portion 4115 to pass through is defined on the base 415. The clearance opening 4151 is larger than the pushing portion 4115 in the second direction, allowing the pushing portion 4115 to slide within the clearance opening 4151 and drive the lock release structure 30 to slide. This prevents the base 415 from interfering with the sliding of the pushing portion 4115 and also prevents the front end of the driving member 411 from being completely suspended due to the setting of the pushing portion 4115, thereby improving the load-bearing stability of the driving member 411.

[0104] Please refer to Figure 11 In some embodiments of the transfer device 100 of the present application, the latch 4111 is provided with a roller 4113 , and when the latch 4111 enters and exits the plug-in port 215 , the roller 4113 rolls against the side wall of the plug-in port 215 .

[0105] It is understood that the connection structure 41 and the connecting member 21 of the present embodiment are connected by the plug-in cooperation between the latch 4111 and the plug-in interface 215. When the latch 4111 is withdrawn from the plug-in interface 215, the contact lock and release structure 30 locks the support bracket 20. At this time, the latch 4111 may contact the side wall of the plug-in interface 215 during the process of entering and exiting the plug-in interface 215. In this embodiment, the latch 4111 is provided with a roller 4113. When the latch 4111 enters and exits the plug-in interface 215, the roller 4113 can roll along the side wall of the plug-in interface 215. This configuration can reduce friction between the latch 4111 and the connecting member 21, preventing mutual wear between the latch 4111 and the connecting member 21. In addition, during the rotation of the roller 4113, the latch 4111 can also be guided to accurately enter the plug-in interface 215, thereby playing a positioning role.

[0106] Please refer to Figure 9 In some embodiments of the transfer device 100 of the present application, the supporting bracket 20 is provided with at least two connecting members 21, at least one connecting member 21 is provided on each side of the fork channel 13, and the connecting structure 41 is provided with at least two groups of the driving mechanisms 413 and the driving members 411, and each group of the driving mechanisms 413 and the driving members 411 is provided with one connecting member 21.

[0107] In this embodiment, two connecting members 21 are provided on the support bracket 20. The two connecting members 21 are respectively located on both sides of the fork channel 13. At the same time, a combination structure of two sets of drive mechanisms 413 and drive members 411 is provided on the connection structure 41 of the fork assembly 40. The two drive members 411 extend and retract in opposite directions to cooperate with the two connecting members 21 respectively. The two drive mechanisms 413 can be set as the same type of mechanism or different types. Each drive mechanism 413 can be a cylinder push mechanism, a connecting rod transmission mechanism, a screw transmission mechanism, or a transmission rod 4133 mechanism as in the aforementioned embodiment, which is not limited here. The two sides of the support bracket 20 are respectively provided with connecting members 21, and are respectively connected to a drive member 411, so that the fork assembly 40 is subjected to balanced force on both sides when pulling the support bracket 20 to slide, thereby improving the stability of the support bracket 20 during the sliding process, which is not limited here.

[0108] Please refer to Figure 11 In some embodiments of the transfer device 100 of the present application, the two sets of drive mechanisms 413 both include sliding members 4131 and transmission rods 4133, and the connecting structure 41 also includes a drive motor and a screw transmission mechanism, so that the sliding members 4131 of the two drive mechanisms 413 are fixed to the screw nuts of the screw transmission mechanism, so that the drive members 411 and the connecting members 21 on both sides are synchronously connected or separated; such a setting can reduce the number of components in the connecting structure 41, make the structure simpler, and improve the synchronization of the transmission process.

[0109] Please refer to Figure 7 In some embodiments of the transfer device 100 of the present application, at least two sets of the locking and releasing structures 30 are provided, and the frame 10 is provided with at least one locking and releasing structure 30 on both sides of the fork channel 13.

[0110] In this embodiment, at least two sets of locking and releasing structures 30 are provided on the frame 10. When the support bracket 20 does not need to move, each side of the support bracket 20 is locked by at least one locking and releasing structure 30. This improves the positional stability and locking strength of the support bracket 20 when locked, and prevents the support bracket 20 from loosening due to external forces. Furthermore, the locking and releasing structures 30 on both sides can have the same or different structures, which is not limited here.

[0111] Please refer to Figure 9 and Figure 10 In some embodiments of the transfer device 100 of the present application, the fork assembly 40 further includes a telescopic structure 43, the telescopic structure 43 including a fixed guide rail 431 and a telescopic carrier 433, the telescopic carrier 433 being slidably disposed on the fixed guide rail 431, and the telescopic direction of the telescopic structure 43 is consistent with the sliding direction of the supporting bracket 20;

[0112] The connecting structure 41 is disposed on the telescopic carrier 433 to move in and out of the fork channel 13 when the telescopic carrier 433 slides.

[0113] In this embodiment, the fork assembly 40 includes a telescopic structure 43 and a connecting structure 41. The telescopic structure 43 is used to drive the connecting structure 41 to slide in and out of the fork channel 13. This eliminates the need to move the entire fork assembly 40 to allow the connecting structure 41 to enter and exit the fork channel 13, improving operational convenience and extending the range of motion of the connecting structure 41, thereby preventing the range of motion of the connecting structure 41 from being limited by the overall structure of the fork assembly 40. Specifically, the telescopic structure 43 includes a fixed guide rail 431 and a telescopic carrier 433 disposed on the fixed guide rail 431. The connecting structure 41 is disposed at the free end of the telescopic carrier 433. When the telescopic carrier 433 slides relative to the fixed guide rail 431, it drives the connecting structure 41 to slide. The telescopic carrier 433 can be driven by a power element such as a drive motor, a pneumatic cylinder, or a hydraulic cylinder. Alternatively, at least one transmission mechanism such as a screw drive mechanism, a gear 435 transmission mechanism, or a belt transmission mechanism can be provided between the power element and the sliding member 4131 to provide sufficient driving force to drive the connecting structure 41, the supporting bracket 20, and the cargo.

[0114] Please refer to Figure 13 In some embodiments of the transfer device 100 of the present application, the telescopic structure 43 further includes:

[0115] drive motor; the drive motor is provided on the fixed guide rail 431; and

[0116] The transmission mechanism includes a rack 437 and at least one gear 435. The gear 435 is arranged on the fixed guide rail 431 and is connected to the drive motor.

The gear 435 is arranged on the fixed guide rail 431, and the rack 437 is arranged on the telescopic carrier 433 and extends along the sliding direction of the telescopic carrier 433. At this time, the gear 435 and the rack 437 are engaged. When the driving motor drives the gear 435 to rotate, the rack 437 can be driven to slide and the telescopic carrier 433 can slide relative to the fixed guide rail 431; using a driving motor as a power component can provide sufficient torque for the gear 435 to drive the connecting structure 41 and the supporting bracket 20 and the cargo to move; using the gear 435 rack 437 transmission mechanism, the transmission accuracy is high, the power consumption of the transmission process is small, and the transmission process is more stable.

[0118] In some embodiments, at least two gears 435 are provided in the fixed guide rail 431, and the at least two gears 435 are arranged in sequence along the length direction of the fixed guide rail 431 and mesh with each other, and at least some of the gears 435 are meshed with the rack 437. With such a configuration, at least two gears 435 can be used to support the rack 437 and drive the rack 437 to slide, thereby improving the stability of the transmission process, and there is no need to set an overly long rack 437.

[0120] In this embodiment, the telescopic carrier 433 includes a top plate and two side plates arranged opposite to each other, so that the fixed guide rail 431 is located between the two side plates, and at least one roller 4331 is provided on the inner wall of the side plate of the telescopic carrier 433, and a track 4311 is provided on the outer wall of the fixed guide rail 431, so that the roller 4331 is rollably set in the track 4311. In this way, when the telescopic carrier 433 is driven by an external force to slide relative to the fixed guide rail 431, the roller 4331 rolls in the track 4311, thereby reducing the friction between the telescopic carrier 433 and the fixed guide rail 431, reducing the friction loss during the sliding process of the telescopic carrier 433, and avoiding mutual wear between the telescopic carrier 433 and the fixed guide rail 431, thereby improving the stability of the telescopic carrier 433 during the sliding process. In some embodiments, a plurality of rollers 4331 are provided on the inner walls of both side panels of the telescopic carrier 433. The plurality of rollers 4331 are arranged side by side along the length direction of the telescopic carrier 433, so that the force on the telescopic carrier 433 is balanced, thereby improving the stability of the telescopic carrier 433 supported on the fixed guide rail 431 and the stability of the sliding process.

[0121] Please refer to Figure 2 、 Figure 14 and Figure 15 In some embodiments of the transfer device 100 of the present application, guide rails 11 are respectively provided on both sides of the frame 10, and the fork channel 13 is formed between the two guide rails 11. Rolling wheels 23 are respectively provided on both sides of the bottom of the supporting bracket 20, and each rolling wheel 23 is provided on the guide rail 11 on the same side, so that the supporting bracket 20 can be slidably provided on the frame 10.

[0122] In this embodiment, guide rails 11 are protruding from both sides of the frame 10, and the guide rails 11 extend along the sliding direction of the supporting bracket 20. A fork channel 13 for the fork assembly 40 to enter and exit is formed between the two guide rails 11. In addition, rolling wheels 23 are respectively provided on both sides of the bottom of the supporting bracket 20. The rolling wheels 23 are supported on the guide rails 11 and can roll along the guide rails 11, so that the supporting bracket 20 can slide relative to the frame 10; the provision of the rolling wheels 23 can reduce the friction between the supporting bracket 20 and the frame 10, reduce the friction loss during the sliding process of the supporting bracket 20, and avoid mutual wear between the supporting bracket 20 and the frame 10, thereby improving the stability of the supporting bracket 20 during the sliding process.

[0123] In some embodiments, a rolling groove 231 is formed around the rolling wheel 23 , and the guide rail 11 is clamped in the rolling groove 231 to prevent the rolling wheel 23 from sliding off the guide rail 11 .
