Description

Technical Field

[0001] This application relates to the field of delivery robots, and more particularly to a delivery robot pickup structure. Background Technology

[0002] Hotels, upscale residential communities, and other venues are using delivery robots to replace manual labor, transporting goods to designated locations and completing the last few hundred meters of delivery, reducing labor costs and facilitating the management of hotels and upscale communities.

[0003] Existing delivery robots typically include a walking mechanism and a transfer box mounted on the walking mechanism. The transfer box is equipped with a sealing cover to open its inner cavity. At this point, the goods need to be manually placed into the inner cavity of the transfer box, and then the sealing cover needs to be closed. This design cannot eliminate the need for manual assistance in placing the goods.

[0004] like Figure 1 As shown, a belt drive 1 can be installed on the sealing cover 10 of the transfer box to transfer the goods in the inner cavity of the transfer box to the sealing cover 10 in a horizontal state. When the sealing cover 10 is lowered to the ground, although the belt drive 1 can transfer the goods to the ground, the belt drive 10 cannot transfer the goods on the ground to the sealing cover 10 at this time, so the goods cannot be retrieved and cannot be moved into the inner cavity of the transfer box.

[0005] Therefore, how to design a pickup structure that can be integrated with a delivery robot has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] This application provides a delivery robot pickup structure to at least solve the above-mentioned technical problems existing in the prior art.

[0007] A delivery robot picking structure is provided, which is installed on the sealing cover of a transfer box and includes a belt drive component installed on the inside of the sealing cover to support the goods and realize the transfer of the goods; The picking component is located between the belt drive component and the sealing cover. The picking component and the sealing cover are slidably connected along a first direction and switch between a first state and a second state. In the first state, the picking component is stored inside the sealing cover. In the second state, the picking component extends out of the sealing cover and is inserted into the bottom of the goods. The picking item also includes a limiting structure, which hooks the goods and switches from the second state to the first state to transfer the goods to the belt drive component; A drive unit, the output of which is poweredly connected to the pickup item to drive the pickup item to move along a first direction.

[0008] In one embodiment, the belt drive includes a first rotating shaft, a second rotating shaft, a first drive motor, and a conveyor belt; The first rotating shaft and the second rotating shaft are distributed along a first direction; the axes of the first rotating shaft and the second rotating shaft are parallel and extend along a second direction, and the plane formed by the first rotating shaft and the second rotating shaft is parallel to the sealing cap; The conveyor belt is sleeved on the outside of the first rotating shaft and the second rotating shaft; the output end of the first drive motor is poweredly connected to the first rotating shaft or the second rotating shaft to drive the conveyor belt to move.

[0009] In one embodiment, a placement space is provided between the belt drive component and the sealing cover, and the retrieval component is installed in the placement space.

[0010] In one embodiment, the picking component includes a pusher frame and a picking plate. The pusher frame is slidably connected to the sealing cover along a first direction. The picking plate forms a first angle with the first direction. The picking plate is rotatably connected to the pusher frame. The limiting structure is disposed on the picking plate on the side away from the pusher frame.

[0011] In one embodiment, the limiting structure is provided with a guide surface that forms an angle with the picking plate, and the limiting structure is also provided with a hooking surface.

[0012] In one embodiment, the sealing cover is provided with a sliding groove arranged along a first direction, the pusher is inserted into the sliding groove, and the outer wall of the pusher and the inner wall of the sliding groove are slidably connected along the first direction.

[0013] In one embodiment, a lifting component is also included, which is fixedly installed on the transfer box along a third direction. The output end of the lifting component is poweredly connected to the sealing cover to push the sealing cover up and down along the third direction.

[0014] In one embodiment, a flipping component is also included, which is installed between the side wall of the transfer box and the side wall of the sealing cover, so that the sealing cover switches between a closed state and an open state.

[0015] In one embodiment, a horizontally arranged transfer member is also provided in the inner cavity of the transfer box. The transfer member receives the goods on the belt drive member and supports the goods.

[0016] Compared with existing technologies, the delivery robot pickup structure proposed in this application has the following advantages: This application involves placing a picking component between a sealing cover and a belt drive component. A driving component pushes the picking component from a first state to a second state along a first direction. At this point, the picking component extends beyond the sealing cover and reaches the bottom of the goods, lifting them up. A limiting structure on the picking component passes over the goods. When the driving component switches the picking component from the second state to the first state, the limiting structure hooks the goods and moves them toward the belt drive component together with the picking component. Under the continuous clamping of the belt drive component and the limiting structure, the friction between the belt drive component and the goods increases, thereby transferring the goods from the picking component to the belt drive component. When the picking component reaches the first state, the sealing cover lifts the goods, transferring them into the inner cavity of the transfer box. The sealing cover then closes the inner cavity of the transfer box, achieving automatic goods retrieval and solving the problem of manual assisted goods retrieval.

[0021] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] The delivery robot includes a walking mechanism and a transfer box mounted on top of the walking mechanism. It also includes a navigation system, a central control unit, a steering system, an environmental monitoring system, etc., to help the delivery robot adapt to complex road environments. Here, the above-mentioned systems all adopt existing technologies on the market without making any improvements to the systems. In this embodiment, the above-mentioned systems will not be described in detail.

[0023] Traditional delivery robots have a sealing cover on the top wall of the transfer box to seal the inner cavity. When the sealing cover is opened, the goods need to be placed in the inner cavity of the transfer box manually, and then the sealing cover is closed. With the cooperation of the navigation system and the walking mechanism, the delivery robot delivers the goods to the designated location. The recipient opens the sealing cover to take out the goods from the inner cavity of the transfer box, thus completing the delivery process. Existing delivery robots cannot achieve the purpose of autonomous picking up and unloading.

[0024] Therefore, in this embodiment, as Figure 2 As shown, the sealing cap 10 is positioned at the rear of the transfer box. The sealing cap 10 can switch between a vertical and a horizontal position, thereby closing or opening the inner cavity of the transfer box. It is worth noting that... Figure 2 The transfer box is in a closed state. Figure 3 The transfer box is in the open position.

[0025] Furthermore, such as Figure 2 and Figure 3 As shown, a belt drive component 1 is provided on the sealing cover 10, and a transfer component 6 is provided in the inner cavity of the transfer box. When the sealing cover 10 opens the inner cavity of the transfer box, the transfer component 6 and the belt drive component 1 are located on the same horizontal plane. The transfer component 6 can transfer the goods in the inner cavity of the transfer box to the belt drive component 1 of the sealing cover 10.

[0026] Specifically, in this embodiment, such as Figure 2 As shown, the transfer component 6 includes a third drive motor 61, a third rotating shaft 62, a fourth rotating shaft 63, and a transfer belt 64. The third rotating shaft 62 and the fourth rotating shaft 63 are on the same horizontal plane and distributed along the first direction X. The axes of the third rotating shaft 62 and the fourth rotating shaft 63 extend along the second direction Y. The transfer belt 64 is sleeved on the outside of the third rotating shaft 62 and the fourth rotating shaft 63. The third drive motor 61 is fixedly mounted on the transfer box, and the output shaft of the third drive motor 61 is fixedly connected to the third rotating shaft 62.

[0027] It is worth noting that the first direction X refers to the direction in which the delivery robot moves forward or backward, and can also be considered as the length direction of the delivery robot, while the second direction Y refers to the width direction of the delivery robot.

[0028] When the goods are inside the transfer box, they are supported by the transfer belt 64. When it is necessary to unload the goods, the third drive motor 61 drives the third rotating shaft 62 to rotate, which in turn drives the transfer belt 64 to feed, so that the goods move from the transfer belt 64 to the sealing cover 10 side, and move the goods out of the transfer box and onto the belt drive component 1 of the sealing cover 10.

[0029] Traditionally, the sealing cover 10 is usually installed on the body of the transfer box in a hinged manner, and then the sealing cover 10 is driven by a drive source to flip from a vertical state (the inner cavity of the transfer box is closed) to a horizontal state (the inner cavity of the transfer box is open).

[0030] However, although this setting can adjust the sealing cover 10 to a horizontal position, it is difficult to unload the goods on the sealing cover 10 to the ground because there is a certain height difference between the inner cavity of the transfer box and the ground.

[0031] Therefore, in this embodiment, improvements are made to the opening and position adjustment of the sealing cap 10; specifically, as follows: Figure 3 and Figure 4 As shown, it also includes a lifting component 4. When the inner cavity of the transfer box is in the open state, the sealing cover 10 is arranged horizontally. The lifting component 4 extends along the third direction Z. The output end of the lifting component 4 is poweredly connected to the sealing cover 10 to push the horizontal sealing cover 10 to lift it.

[0032] The third direction Z refers to the vertical direction. The lifting component 4 can be one of an electric push rod, a linear cylinder, or a hydraulic cylinder; in this embodiment, an electric push rod is selected as the lifting component 4.

[0033] The electric push rod is fixedly installed on the body of the transfer box and extends along the third direction Z. The output end of the lifting component 4 is connected to the sealing cover 10.

[0034] Specifically, such as Figure 4 As shown, a first support rod 102 extending along the second direction Y is fixedly provided on the side wall of the sealing cover 10, and the output end of the lifting component 4 is hinged to the first support rod 102.

[0035] Since the lifting component 4 needs to push the sealing cover 10 to descend to the ground in a horizontal state, this embodiment also includes a flipping component 5 to ensure that the sealing cover 10 can still be lifted and lowered under the drive of the lifting component 4 after it can be flipped from a vertical state to a horizontal state.

[0036] Specifically, such as Figure 4 and Figure 5 As shown, it is worth noting that a second support rod 103 extending along the second direction Y is also fixedly provided on the side wall of the sealing cover 10. A first gap 71 is formed between the first support rod 102 and the second support rod 103. When the sealing cover 10 is in a vertical state, the first support rod 102 and the second support rod 103 are both on the extension line of the electric push rod, and the second support rod 103 is located below the first support rod 102.

[0037] like Figure 5 As shown, the flipping component 5 includes a support frame 51 with an opening on one side, and a guide groove 52 set on the side wall of the transfer box. When the sealing cover 10 is in a vertical state, the second support rod 103 extends into the guide groove 52 and slides along the trajectory of the guide groove 52. The guide groove 52 is arc-shaped, and the opening of the support frame 51 is aligned with the end of the guide groove 52. The support frame 51 is located at point O on one side of the extension line of the electric push rod. The intersection of the axis of the support frame 51 on the horizontal plane and the extension line of the electric push rod is point B. OB is the second spacing 72. Specifically, the second spacing 72 is equal to the first spacing 71.

[0038] With the above setup, during the process of changing the sealing cover 10 from a vertical state to a horizontal state, the electric push rod extends and pushes the sealing cover 10 downward along the third direction Z via the first support rod 102. Since the second support rod 103 is located in the guide groove 52, at this time, the second support rod 103 slides in the guide groove 52 and gradually deviates from the extension line of the electric push rod, thereby causing the sealing cover 10 to flip around the first support rod 102. As the electric push rod continues to push the sealing cover 10 downward along the third direction Z via the first support rod 102, the flipping angle of the sealing cover 10 gradually increases. When the second support rod 103 enters point O in the bearing frame 51 through the end of the guide groove 52, the first support rod 102 reaches point B on the extension line of the electric push rod. The first support rod 102 and the second support rod 103 are on the same horizontal plane, thereby keeping the sealing cover 10 in a horizontal state.

[0039] After the sealing cover 10 reaches a horizontal position, in order to allow the sealing cover 10 to slide along the third direction Z under the push of the lifting member 4, thereby bringing the sealing cover 10 into contact with the ground, therefore, in this embodiment, as follows... Figure 3 and Figure 5 As shown, the side wall of the transfer box is provided with a guide groove 104 extending along the third direction Z. A guide plate 53 extending along the third direction Z is fixedly provided on the bearing frame 51. A guide block 531 inserted into the guide groove 104 is fixedly provided on the guide plate 53. The side wall of the guide block 531 and the inner wall of the guide groove 104 are slidably connected along the third direction Z.

[0040] With the above configuration, the electric push rod continues to push the sealing cover 10 downward along the third direction Z via the first support rod 102. At this time, even if the sealing cover 10 has a tendency to flip around the first support rod 102, such as Figure 5 As shown, since the guide block 531 abuts against the side wall of the guide groove 104, it can limit the continued clockwise rotation of the sealing cover 10 to ensure that the sealing cover 10 is horizontal.

[0041] It is worth noting that when the sealing cover 10 is in a horizontal position, the second support rod 103 is closer to the rear of the transfer box than the first support rod 102. Both the first and second support rods 102 are located on one side of the rear of the transfer box. After the goods are moved onto the belt drive 1 via the transfer component 6, the center of gravity of the goods is further away from the transfer box than the first support rod 102, thus better maintaining the horizontal position of the sealing cover 10. With the push of the electric push rod, the sealing cover 10 lowers the goods to the ground position via the belt drive 1. At this point, the belt drive 1, driven by the belt drive 1, moves the goods along the first direction X, thereby transferring the goods to the ground.

[0042] After the goods are unloaded from the transfer container, the sealing cover 10 needs to be raised to seal the opening at the rear of the transfer container. At this time, the electric push rod applies an upward lifting force to the sealing cover 10 through the first support rod 102. Under the action of the guide block 531 and the guide groove 104, the bearing frame 51 of the sealing cover 10 rises synchronously with the first support rod 102 to maintain the horizontal state of the sealing cover 10 during the raising process. When the guide block 531 abuts against the top wall of the guide groove 104, the bearing frame 51 moves to the upper limit position. At this time, the electric push rod continues to drive the first support rod 102 to move upward. At this time, the second support rod 103 will transfer from the bearing frame 51 to the guide groove 52, thereby gradually flipping the sealing cover 10 from the horizontal state and slowly closing the opening at the rear of the transfer container. When the second support rod 103 moves to the extension line of the electric push rod, the closing action of the opening at the rear of the transfer container is completed.

[0043] It is worth noting that when the second support rod 103 detaches from the support frame 51, in order to prevent the support frame 51 from falling downwards under its own weight, in this embodiment, as follows: Figure 3 As shown, it also includes a spring 54, one end of which is fixedly connected to the guide block 531, and the other end of which is connected to the inner wall of the guide groove 104, thereby maintaining the carrier frame 51 at the end outlet position of the guide groove 52.

[0044] In order to enable the goods to move along the first direction X on the sealing cover 10, in this embodiment, as follows: Figure 6 and Figure 7 As shown, the belt drive component 1 includes a first rotating shaft 11, a second rotating shaft 12, a first drive motor 13, and a conveyor belt 14. With the sealing cover 10 in a horizontal position as a reference, the first rotating shaft 11 and the second rotating shaft 12 are distributed along a first direction X, and their axes are parallel and extend along a second direction Y. The conveyor belt 14 is sleeved on the outside of the first rotating shaft 11 and the second rotating shaft 12. The first drive motor 13 is fixedly mounted on the sealing cover 10, and its output shaft is fixedly connected to the first rotating shaft 11. The first rotating shaft 11 and the second rotating shaft 12 are rotatably connected to the sealing cover 10.

[0045] With the above configuration, when the first drive motor 13 is in operation, it can drive the first rotating shaft 11 to rotate. Since the conveyor belt 14 is mounted on the first rotating shaft 11 and the second rotating shaft 12, the conveyor belt 14 is driven by the first rotating shaft 11, thereby driving the movement of the goods on the conveyor belt 14.

[0046] It is worth noting that the first rotating shaft 11 is the driving shaft, and the second rotating shaft 12 is the driven shaft.

[0047] The first drive motor 13 and the third drive motor 61 are both stepper motors, which can realize the forward and reverse rotation of the conveyor belt 14 and the transfer belt 64, thereby facilitating the loading and unloading of goods.

[0048] like Figure 6 and Figure 8 As shown, a placement space 100 is left between the belt drive component 1 and the sealing cover 10. Inside the placement space 100, a picking component 2 is provided that slides along the first direction X. The picking component 2 switches between a first state and a second state along the first direction X via the drive component 3. Specifically, in the first state, the picking component 2 is stored in the placement space 100 to reduce interference during the unloading process. In the second state, the picking component 2 extends out of the sealing cover 10 along the first direction X and extends diagonally downwards, so that the picking component 2 forms a first angle 23 with the ground. As the picking component 2 extends outwards from the placement space 100, it gradually inserts into the bottom of the goods and lifts the goods upwards.

[0049] Specifically, in order to enable pickup item 2 to switch between the first state and the second state, in this embodiment, as follows: Figure 6 and Figure 9 As shown, the driving component 3 includes a second driving motor 31 and a lead screw 32. The lead screw 32 extends along the first direction X and is threadedly connected to the picking component 2. The second driving motor 31 is fixedly installed on the sealing cover 10, and the output shaft of the second driving motor 31 is fixedly connected to the lead screw 32.

[0050] Furthermore, such as Figure 4 and Figure 9 As shown, the picking component 2 includes a pusher frame 21 and a picking plate 22. The sealing cover 10 is provided with a slide groove 101 arranged along the first direction X. The pusher frame 21 passes through the slide groove 101 and is threadedly connected to the lead screw 32. The side wall of the pusher frame 21 is slidably connected to the inner wall of the slide groove 101 along the first direction X. One end of the picking plate 22 is rotatably connected to the pusher frame 21 along the second direction Y. The picking plate 22 is inclined and contacts the sealing cover 10 to form an included angle. As the picking plate 22 moves in the first direction X position, the angle of the first included angle 23 changes.

[0051] It is worth noting that the side of the picking plate 22 away from the push frame 21 abuts against the sealing cover 10. When the sealing cover 10 is in a vertical position and closes the inner cavity of the transfer box, the picking plate 22 abuts against the belt drive 1, thereby keeping the picking plate 22 within the placement space 100.

[0052] When it is necessary to pick up the goods, such as Figure 10As shown, the sealing cover 10 is lowered to the ground by the lifting component 4. At this time, the second drive motor 31 drives the lead screw 32 to rotate, and the pusher 21 moves along the slide 101 in the first direction X, thereby slowly pushing the picking plate 22 outward of the placement space 100. At this time, the bottom wall of the picking plate 22 abuts against the sealing cover 10. As the picking plate 22 moves forward, the first included angle 23 between the picking plate 22 and the horizontal plane gradually increases. The picking plate 22 is inserted into the bottom of the goods and lifts the goods. Then, the picking plate 22 is retracted to the placement space 100 by the lead screw 32, and the goods are transferred to the belt drive component 1 by the picking plate 22.

[0053] To address the issue that during the picking process, the goods move relative to the picking plate 22 and cannot be transferred to the belt drive 1, in this embodiment, as follows: Figure 6 , Figure 8 and Figure 9 As shown, a limiting structure 20 is provided at the end of the picking plate 22 away from the push frame 21. The limiting structure 20 is used to restrict the goods from slipping off the picking plate 22.

[0054] Specifically, the limiting structure 20 includes a guide surface 201 and a hook surface 202, wherein the hook surface 202 is perpendicular to the picking plate 22, and the guide surface 201 is used to connect the hook surface 202 and the end of the picking plate 22.

[0055] It is worth noting that when the picking plate 22 is inserted into the bottom of the goods, the guide surface 201 of the limiting structure 20 first contacts the goods to scoop them up. After the limiting structure 20 passes through the bottom of the goods, the hook surface 202 contacts the side wall of the goods.

[0056] With the above setup, when the picking plate 22 retracts into the placement space 100, the hook surface 202 pushes the goods along with the picking plate 22 towards the belt drive 1. The side wall of the goods away from the hook surface 202 contacts the conveyor belt 14 of the belt drive 1. As the picking plate 22 continues to retract, the friction between the conveyor belt 14 and the goods increases, thereby gradually transferring the goods to the upper part of the conveyor belt 14. When the goods are transferred to the designated position on the conveyor belt 14, the first drive motor 13 stops operating, and the second drive motor 31 retracts the picking plate 22 into the placement space 100 through the lead screw 32. The electric push rod drives the sealing cover 10 to rise through the first support rod 102. When the belt drive 1 and the transfer member 6 are on the same horizontal plane, the belt drive 1 continues to operate, thereby transferring the goods onto the transfer member 6. The third drive motor 61 operates, thereby adjusting the position of the goods on the transfer belt 64.

[0057] Subsequently, the electric push rod drives the first support rod 102 to move upward. At this time, the second support rod 103 moves out from the bearing frame 51 and moves towards the extension line of the electric push rod through the guide groove 52. At this time, the sealing cover 10 flips from the horizontal state to the vertical state, thereby sealing the inner cavity of the transfer box and completing the cargo retrieval operation.
