[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, thus reducing labor costs and facilitating the management of hotels and upscale residential communities.

[0003] Existing delivery robots typically consist of a walking mechanism and a transfer container mounted on the walking mechanism. The transfer container has a sealing cover to open its interior. A locking mechanism is installed on either the sealing cover or the transfer container to secure it in place. During cargo transfer, the delivery robot arrives at the designated location and opens the transfer container. A person then places the goods into the interior of the transfer container, closes the sealing cover, and the delivery robot uses its navigation and walking systems to deliver the goods to the receiving location. The recipient then needs to open the sealing cover and manually remove the goods from the interior of the transfer container. This design cannot eliminate the need for manual assistance in placing or retrieving goods, thus affecting the delivery efficiency of the delivery robot.

[0004] Therefore, how to design a delivery robot that can automatically unload goods has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] A delivery robot unloading device is provided, which is installed on the delivery robot and includes a sealing cover. The sealing cover is installed on the side wall of the transfer box and switches between a first state and a second state to close or open the inner cavity of the transfer box. A driving component is installed on the transfer box. The output end of the driving component is poweredly connected to the sealing cover. The driving component pushes the sealing cover from a first state to a second state and causes the sealing cover in the second state to move up and down along a first direction. A first conveyor and a second conveyor, one of which is installed in the inner cavity of the transfer box and the other is installed on the sealing cover. In the second state, the sealing cover is arranged horizontally, and the first conveyor and the second conveyor are located on the same horizontal plane, so that the goods are transferred on the first conveyor and the second conveyor.

[0007] In one embodiment, the driving component includes a driving source and a reversing structure. The driving source is mounted on the transfer box, and the output end of the driving source is poweredly connected to the sealing cover. The reversing structure is mounted on the sealing cover or the transfer box, and the sealing cover switches from a first state to a second state under the driving force of the driving source and the reversing action of the reversing structure.

[0008] In one embodiment, the drive source is one of an electric push rod, a cylinder, or a hydraulic cylinder. The housing of the drive source is fixedly mounted on the transfer box, and the output end of the drive source is rotatably connected to the sealing cover and extends along a first direction.

[0009] In one embodiment, a first support rod extending along a second direction is fixedly provided on the side wall of the sealing cover. The first support rod is rotatably connected to the output end of the drive source, and the drive source pushes the first support rod up and down along a first direction.

[0010] In one embodiment, the reversing structure includes a guide groove, a second support rod, and a carrier frame. The second support rod is fixedly installed on the side wall of the sealing cover, and a first gap is formed between the second support rod and the first support rod. The carrier frame is disposed on the transfer box, and the carrier frame is located on one side of the extension line of the drive source output end. The carrier frame and the extension line of the drive source output end form a second gap, and the first gap and the second gap are equal. The guide groove is disposed on the side wall of the transfer box, the second support rod extends into the guide groove and forms a sliding connection, and one side opening of the bearing frame is opposite to the end opening of the guide groove.

[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 100 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 robot transfer box 100 has a sealing cover 10 on its top wall to seal the inner cavity of the transfer box 100. When the sealing cover 10 is opened, the goods need to be placed in the inner cavity of the transfer box 100 manually, and then the sealing cover 10 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 10 to take out the goods from the inner cavity of the transfer box 100, thus completing the delivery process. Existing delivery robots cannot achieve the purpose of autonomous picking up and unloading.

[0024] Therefore, this application mainly adjusts the transfer box 100 and the sealing cover 10 of the delivery robot so that the delivery robot can autonomously complete the purpose of unloading goods.

[0025] like Figure 1 and Figure 2As shown, the transfer box 100 has an opening on its side wall to allow goods to enter its inner cavity. A sealing cap 10 is disposed on the side wall of the transfer box 100 to seal its inner cavity. During this process, the sealing cap 10 has a first state and a second state. In the first state, the sealing cap 10 closes the inner cavity of the transfer box 100; in the second state, the sealing cap 10 opens the inner cavity of the transfer box 100.

[0026] Under normal circumstances, the sealing cover 10 can be hinged to the transfer box 100. In the first case, the sealing cover 10 is hinged to the transfer box 100 via a rotating shaft. The axis of the rotating shaft is set along the first direction X, where the first direction X refers to the vertical direction. Alternatively, the axis of the rotating shaft can be set along the horizontal direction so that the sealing cover 10 can switch between the vertical and horizontal states.

[0027] In this application, after the inner cavity of the transfer box 100 is opened, the sealing cover 10 is used to support the goods and then transfer the goods to the ground. Therefore, the sealing cover 10 will not be installed on the transfer box in a hinged manner in this application.

[0028] Specifically, the technical solution of this application is as follows: a first conveying component 3 is provided in the inner cavity of the transfer box 100, a second conveying component 4 is provided on the sealing cover 10, and a driving component 2 is also included. The driving component 2 pushes the sealing cover 10 from the first state to the second state. It can be understood that the sealing cover 10 switches from the vertical state to the horizontal state to open the inner cavity of the transfer box 100, and then the driving component 2 continues to push the sealing cover 10 to descend, so as to eliminate the height difference between the transfer box 100 and the ground, and the goods are transferred to the ground with the help of the sealing cover 10.

[0029] An explanation is needed here. Figure 1 With the inner cavity of the transfer box 100 closed, the sealing cover 10 is in its first state. Figure 2 With the inner cavity of the transfer box 100 open, the sealing cover 10 is in its second state. Figure 3 The sealing cover 10 is lowered to the ground using the drive unit 2, thereby facilitating the transfer of goods.

[0030] In order to switch the sealing cap 10 from the first state to the second state, in this embodiment, as follows: Figure 4As shown, the driving component 2 includes a driving source 21 and a reversing structure 22. The driving source 21 is fixedly installed on the side wall of the transfer box 100. The output end of the driving source 21 extends along the first direction X and is poweredly connected to the sealing cover 10, thereby pushing the sealing cover 10 to rise and fall along the first direction X. The reversing structure 22 is set on the transfer box 100 or the sealing cover 10. When the sealing cover 10 moves downward, the reversing structure 22 flips the sealing cover 10 from a vertical state to a horizontal state, thereby completing the switching of the state of the sealing cover 10.

[0031] Specifically, in this embodiment, such as Figure 4 and Figure 7 As shown, a first support rod 5 extending along the second direction Y is provided on the side wall of the sealing cover 10, wherein the output end of the drive source 21 is rotatably connected to the first support rod 5.

[0032] The reversing structure 22 includes a guide groove 221, a second support rod 222, and a bearing frame 223. The second support rod 222 is fixedly installed on the side wall of the sealing cover 10. Figure 4 As shown, when the sealing cover 10 is in the first state, the sealing cover 10 is vertically set, the second support rod 222 is located below the first support rod 5, the second support rod 222 is located on the extension line of the output end of the drive source 21, the guide groove 221 is arc-shaped and is set on the side wall of the transfer box 100, at this time the second support rod 222 is inserted into the guide groove 221, the inner wall of the guide groove 221 is slidably connected to the outer wall of the second support rod 222, a first gap 61 is formed between the first support rod 5 and the second support rod 222, the bearing frame 223 is set on the side wall of the transfer box 100 and is located on one side of the extension line of the output end of the drive source 21, wherein one side of the bearing frame 223 is provided with an opening and is aligned with the opening at the end of the guide groove 221 to support the second support rod 222 that slides out from the guide groove 221, the bearing frame 223 and the extension line of the output end of the drive source 21 form a second gap 62, wherein the second gap 62 is equal to the first gap 61. It is worth noting that the support frame 223 is closer to the opening of the transfer box 100 than the extension line of the output end of the drive source 21. The guide groove 221 here is arc-shaped.

[0033] With the above settings, as the drive source 21 pushes the sealing cover 10 downward along the first direction X via the first support rod 5, the first support rod 5 moves along the first direction X. At this time, the second support rod 222 slides towards the side of the carrier frame 223 within the guide groove 221. At this time, the second support rod 222 deviates from the extension line of the output end of the drive source 21. Therefore, the sealing cover 10 begins to tilt, gradually opening the inner cavity of the transfer box 100. When the first support rod 5 slides downward and is on the same horizontal plane as the carrier frame 223, the second support rod 222 slides into the carrier frame 223 and stops sliding, so that the sealing cover 10 remains in a horizontal state.

[0034] Furthermore, in order to allow the sealing cap 10 to continue moving downwards under the push of the drive source 21 while maintaining a horizontal position, it is necessary to restrict the sealing cap 10 from continuing to rotate around the first support rod 5, such as... Figure 5 and Figure 7 As shown, the cross-section of the support frame 223 is C-shaped to allow the second support rod 222 to slide in, and it also includes a guide structure 23 so that the support frame 223 can move only along the first direction X.

[0035] Specifically, the guide structure 23 includes a guide groove 231, a guide plate 232, a guide block 233, and a spring 234. The guide groove 231 is disposed on the side wall of the transfer box 100 and extends along the first direction X. The guide block 233 and the support frame 223 are both fixedly mounted on the guide plate 232. The guide block 233 extends into the guide groove 231, and the outer wall of the guide block 233 is slidably connected to the inner wall of the guide groove 231 along the first direction X. It is worth noting that the guide block 233 is rectangular and abuts against the inner wall of the guide groove 231 to restrict the rotation of the support frame 223.

[0036] With the above settings, as Figure 5 As shown, when the sealing cap 10 is in the second state and is horizontal, the drive source 21 pushes the sealing cap 10 downward through the first support rod 5. At this time, the guide plate 232 and the second support rod 222 move downward synchronously, and the bearing frame 223 restricts the sealing cap 10 from flipping around the first support rod 5.

[0037] It is worth noting that both the first support rod 5 and the second support rod 222 are mounted on the side wall of the sealing cover 10 and are located on the side near the rear of the transfer box 100. When the goods are transferred from the inner cavity of the transfer box 100 to the sealing cover 10, the goods are located on the other side of the second support rod 222 relative to the axis of the first support rod 5.

[0038] When the drive source 21 drives the sealing cover 10 from Figure 3 state towards Figure 2 When the state changes, the guide structure 23 can maintain the stable lifting and lowering of the sealing cover 10. When the sealing cover 10 reaches... Figure 2 When the position is reached, the end of the support frame 223 is aligned with the end of the guide groove 221. The support frame 223 can no longer move upward along the first direction X. At this time, the drive source 21 continues to drive the sealing cover 10 to move upward along the first direction X. At this time, the first support rod 5 moves to above the horizontal plane of the support frame 223. The second support rod 222 starts to slide from inside the support frame 223 into the guide groove 221. When the drive source 21 can no longer drive the sealing cover 10 to rise, the second support rod 222 is back on the extension line of the output end of the drive source 21.

[0039] It is worth noting that when the sealing cover 10 is in the second state, the first conveying component 3 in the inner cavity of the transfer box 100 and the second conveying component 4 on the sealing cover 10 are on the same horizontal plane so as to transfer the goods on the first conveying component 3 to the second conveying component 4.

[0040] Specifically, such as Figure 1 and Figure 6 As shown, the first conveyor 3 includes a first drive motor 31, a first rotating shaft 32, a second rotating shaft 33, and a first conveyor belt 34. The first rotating shaft 32 and the second rotating shaft 33 are distributed along the third direction Z. The first rotating shaft 32 and the second rotating shaft 33 are rotatably connected to the transfer box 100. The first drive motor 31 is fixedly installed on the transfer box 100. The output end of the first drive motor 31 is fixedly connected to the first rotating shaft 32. The first conveyor belt 34 is sleeved on the first rotating shaft 32 and the second rotating shaft 33, and the first conveyor belt 34 carries the goods in the inner cavity of the transfer box 100.

[0041] The first conveyor belt 34 is connected end to end to form a ring. The support plate is inserted between the first rotating shaft 32 and the second rotating shaft 33 and is located within the ring of the first conveyor belt 34. The support plate is fixedly connected to the transfer box 100 to enhance the support capacity for goods.

[0042] like Figure 8 As shown, the second conveyor 4 includes a second drive motor 41, a third rotating shaft 42, a fourth rotating shaft 43, and a second conveyor belt 44. The third rotating shaft 42 and the fourth rotating shaft 43 are distributed along the third direction Z. The third rotating shaft 42 and the fourth rotating shaft 43 are rotatably connected to the sealing cover 10. The second drive motor 41 is fixedly installed on the sealing cover 10. The output end of the second drive motor 41 is fixedly connected to the third rotating shaft 42. The second conveyor belt 44 is sleeved on the outside of the third rotating shaft 42 and the fourth rotating shaft 43, and supports the goods on the sealing cover 10.

[0043] Both the first drive motor 31 and the second drive motor 41 are stepper motors, which can rotate in both directions to move goods.

[0044] When the second support rod 222 is detached from the bearing frame 223 and transferred to the guide groove 221, in order to prevent the bearing frame 223 from falling downward under the action of gravity, one end of the spring 234 is fixedly connected to the guide block 233, and the other end of the spring 234 is fixedly connected to the inner wall of the guide groove 231.

[0045] When the sealing cap 10 is not pushed by the driving member 2 in the first state, the spring 234 pushes the guide block 233 so that the opening on one side of the bearing frame 223 is aligned with the opening at the end of the guide groove 221.

[0046] The drive source 21 can be selected from one of the following: electric push rod, cylinder, or hydraulic cylinder. In this embodiment, the drive source 21 is selected from the electric push rod.
