[0036] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
[0037] This embodiment relates to a delivery robot that can be lifted, opened and closed. Figure 1-Figure 7 , including: a mobile carrier 100, a lifting device 200, a placement platform 300 and a box 400. The lifting device 200 is mounted on the mobile carrier 100; the placement platform 300 is mounted on the upper side of the lifting device 200 for placing items 700; the lifting device 200 can lift the placement platform 300 to raise the items 700, and the user does not need to bend over or turn sideways to take the items 700, which reduces physical energy consumption and is more convenient for users to take the items 700; the box 400 is mounted on the mobile carrier 100, and wraps the lifting device 200 and the placement platform 300, and the box 400 is configured to have an openable and closable top surface; after the lifting device 200 is lowered, a space for placing the items 700 is left between the top surface of the placement platform 300 and the box 400. In this embodiment, the box 400 is designed in such a way that, on the one hand, it protects the items 700 and prevents them from falling during transportation; on the other hand, the box 400 is configured with an openable and closable top surface, which can make full use of the vertical space. Compared with some delivery robots with side door designs, it is more suitable for scenes with narrow space in production and life.
[0038] In this embodiment, refer to Figure 1-Figure 4The box 400 includes: a first shell 410 whose lower end is rotatably mounted on the mobile vehicle 100 and a second shell 420 whose lower end is rotatably mounted on the mobile vehicle 100. The first shell 410 and the second shell 420 cooperate with the package lifting device 200 and the placement platform 300; when the first shell 410 and the second shell 420 rotate outward, the top surface of the first shell 410 is away from the top surface of the second shell 420, so that the top surface of the box 400 is opened. Therefore, when the user needs to take out the item 700 in the box 400 or place the item 700 into the box 400, it is only necessary to rotate the first shell 410 and the second shell 420 to open, which is simple, convenient and fast to operate. In addition, the first shell 410 and the second shell 420 are rotated to both sides to open and combine with the lifting device 200 to rise, and the item 700 is gradually displayed, which can increase the sense of ritual and provide emotional value to the user when taking the item 700. In this embodiment, a rotating shaft is disposed at the lower end of the first shell 410 and the second shell 420, and a rotating shaft seat corresponding to the rotating shaft is disposed on the mobile carrier 100, so that the first shell 410 and the second shell 420 can rotate outward, so that the top surface of the box body 400 is opened. In other embodiments, the first shell 410 and the second shell 420 can also be rotated and opened in other forms.
[0039] In this embodiment, refer to Figure 1-Figure 4 The lifting and opening distribution robot also includes: a first connecting rod 500, one end of which is rotatably mounted on the placement platform 300 and the other end of which is rotatably mounted on the first shell 410, and a second connecting rod 600, one end of which is rotatably mounted on the placement platform 300 and the other end of which is rotatably mounted on the second shell 420; when the placement platform 300 is driven to rise by the lifting device 200, the first shell 410 is driven to expand outward by the first connecting rod 500, and the second shell 420 is driven to expand outward by the second connecting rod 600; when the placement platform 300 is driven to descend by the lifting device 200, the first shell 410 is driven to be retracted inward by the first connecting rod 500, and the second shell 420 is driven to be retracted inward by the second connecting rod 600, so as to close the box body 400.
[0040] Specifically, refer to Figure 1-Figure 4 When the lifting device 200 lifts the placement platform 300 to the highest point, the placement platform 300 is close to the top surface of the box 400, and one end of the first connecting rod 500 and the second connecting rod 600 rotatably assembled on the placement platform 300 is higher than one end of the first connecting rod 500 and the second connecting rod 600 rotatably assembled on the first shell 410 and the second shell 420. When the lifting device 200 lowers the placement platform 300 to the lowest point, the placement platform 300 is close to the lower end of the box 400, and one end of the first connecting rod 500 and the second connecting rod 600 rotatably assembled on the placement platform 300 is lower than one end of the first connecting rod 500 and the second connecting rod 600 rotatably assembled on the first shell 410 and the second shell 420.
[0041] In this process, the lifting device 200 is driven to rise or fall, driving the placement platform 300 to rise or fall, and at the same time, the first shell 410 and the second shell 420 are driven to expand outward or retract inward through the first connecting rod 500 and the second connecting rod 600, so as to realize the lifting and lowering linkage of the lifting device 200 and the opening and closing of the box 400, so that the lifting device 200 can be driven to rise and fall by one driving device and the opening and closing of the box 400 can be completed, thereby saving time, saving production costs and simplifying the work process. In some embodiments, the lifting device 200 can be fixed at a set height during the lifting process. Therefore, during the expansion or retraction process of the first connecting rod 500 and the second connecting rod 600 linked to the lifting device 200, the box 400 can also be partially expanded or fully expanded, so as to meet the needs of users to take and place different items 700 or display items 700, and to be more suitable for items 700 of different sizes.
[0042] In this embodiment, the lifting device 200 is a multi-stage retractable column. The multi-stage retractable column vertical design does not occupy too much space on the mobile vehicle 100, ensuring that the first shell 410 and the second shell 420 are at a set distance, ensuring that the first connecting rod 500 and the second connecting rod 600 can respectively drive the first shell 410 and the second shell 420 to expand outward and retract inward. In other embodiments, the lifting device 200 can also be a scissor structure.
[0043] Reference Figure 2-Figure 7 , there are two first connecting rods 500 and two second connecting rods 600, the two first connecting rods 500 are located on the same side, and the two second connecting rods 600 are located on the other side, and in this embodiment, the two first connecting rods 500 and the two second connecting rods 600 are symmetrically distributed, so as to better connect the first shell 410 and the second shell 420, prevent the first shell 410 and the second shell 420 from falling during use, and the opening angles of the first shell 410 and the second shell 420 are the same. In other embodiments, the first connecting rod 500 and the second connecting rod 600 can be provided with one each and symmetrically distributed; or multiple first connecting rods can be provided each and symmetrically distributed around the circumference.
[0044] In some embodiments, the delivery robot that can be lifted and opened and closed further includes: a first telescopic rod with one end mounted on the placement platform 300 and the other end mounted on the first shell 410; and a second telescopic rod with one end mounted on the placement platform 300 and the other end mounted on the second shell 420; when the first telescopic rod is extended, the first shell 410 is driven to expand outward, and when the second telescopic rod is extended, the second shell 420 is driven to expand outward; when the first telescopic rod is retracted, the first shell 410 is driven to be retracted inward, and when the second telescopic rod is retracted, the second shell 420 is driven to be retracted inward. Further, one end of the first telescopic rod is rotatably mounted on the placement platform 300, and the other end is rotatably mounted on the first shell 410; one end of the second telescopic rod is rotatably mounted on the placement platform 300, and the other end is rotatably mounted on the second shell 420. Taking advantage of the telescopic rod's ability to be extended and retracted, during the process of the lifting device 200 rising or falling, the length of the first telescopic rod and the second telescopic rod is adjusted to expand or retract the first and second shells 420, so as to facilitate the user to take and place the items 700. In addition, the first telescopic rod and the second telescopic rod can also adjust the operating length of the telescopic rod according to different scene requirements, and only partially or completely unfold the box 400 to meet the needs of different users to take the items 700 and adapt to different scenes.
[0045] In other embodiments, the box 400 includes: a plurality of shells; the top surfaces of the plurality of shells can be relatively moved to open or close the top surface of the box 400. The box 400 is provided with a plurality of shells, and the top surface of each shell can be relatively moved, so that the top surface opening area of the box 400 is larger and the obstruction of the surrounding shells during the process of taking and placing the object 700 is less.
[0046] In some embodiments, the box 400 further includes: a shell with an opening on the top surface, and a cover mounted on the shell for opening or closing the opening; the user can directly take out the items 700 in the box 400 from the top surface by opening the cover on the shell, or after opening the cover, use the lifting device 200 to lift the items 700 on the placement platform 300, so that the user can take them out by himself, thereby improving the convenience of the user taking the items 700. During the lifting process, the lifting device 200 can be used to lift the placement platform 300 to the highest point, so that the placement platform 300 is slightly higher than the top surface of the box 400, which is more convenient for the user to take the items 700.
[0047] In this embodiment, refer to Figure 2-Figure 4 The lower ends of the sides where the first shell 410 and the second shell 420 are in contact are provided with avoidance slopes to avoid collisions during the outward rotation of the first shell 410 and the second shell 420, thereby limiting the rotation and opening angles of the first shell 410 and the second shell 420, thereby causing the top surface opening area of the box body 400 to be too small, affecting the taking and placement of the items 700.
[0048] In this embodiment, the box 400 is provided with a hollow structure so that the user can observe the items 700 in the box 400, and the hollow design of the box 400 increases the aesthetic appearance of the delivery robot when it is lifted, opened and closed. When the delivered items 700 are fresh food, the hollow structure design can provide a channel for air circulation and increase the amount of air circulation, thereby preventing the items 700 from spoiling or even dying due to lack of oxygen. In other embodiments, the box 400 can also be a transparent structure, which is more convenient for users to observe the items 700 in the box 400.
[0049] In this embodiment, the mobile carrier 100 is an AGV smart car, which can fully navigate autonomously, adopts two navigation methods, dual laser radar and visual navigation, and has the advantages of flexible planning path, accurate positioning, and can be applied to various environments, and can meet the needs of different delivery scenarios; and a dedicated QR code can be attached to the shell, and the user can only open the box 400 after scanning the dedicated QR code, thereby increasing the safety of the items 700 during the delivery process. In some embodiments, a scanning device can also be added to the shell, and the user can provide a dedicated QR code for scanning to open the box 400, thereby ensuring the safety of the items 700 in the box 400. In addition, in this embodiment, the mobile carrier 100 adopts a Mecanum wheel or a steering wheel, which can make any direction translation and self-rotation in the plane, realize omnidirectional movement, and is suitable for environments with limited space and some narrow working channels, thereby increasing the utilization of space. The mobile carrier 100 is designed to carry 100 to 500 kilograms of items 700 in terms of load, expand the load range of the delivery robot that lifts, opens and closes, and has a strong endurance. It can last for twelve hours after charging for two hours, ensuring a longer working time. In some embodiments, the mobile vehicle 100 may also be other movable devices.
[0050] The advantages of the utility model are as follows: the top surface of the box body 400 is configured to be openable and closable, and the articles 700 on the placement platform 300 are lifted or lowered by the lifting device 200, so that the user can take and place the articles 700, and the process is simple and convenient; at the same time, the opening and closing of the box body 400 is linked with the lifting and lowering of the lifting device 200, so that one driving device can drive the lifting and lowering of the lifting device 200 and complete the opening and closing of the box body 400, which saves time and effort and can also save production costs.
