[0001] This invention relates to the field of robot packaging boxes, and more particularly to a robot packaging box, an autonomous charging system, and a charging method. Background Technology

[0002] Currently, to ensure the safety of quadruped robots during transportation, they need to be properly packaged in boxes. However, traditional quadruped robot packaging boxes have a limited function, only handling storage and transport. For example, a robot dog packaging structure (Chinese Patent Publication No. CN218368869U) is disclosed in the prior art. This packaging structure has a storage box and side covers, and uses clips and padding inside the storage box to secure the loaded robot dog. However, this type of packaging box has a single function, only protecting the robot dog from damage during transportation. Once unpacked, it is discarded or left idle, resulting in significant resource waste. Furthermore, quadruped robot charging stations are often independently installed, requiring the robot to have a dedicated charging station installed at the work site. This occupies space and increases purchase costs. Additionally, charging stations directly fixed to the ground at the production site are easily damaged by collisions. Summary of the Invention

Similarly, the terms “an” or “a” and similar terms do not indicate a limitation of quantity, but rather indicate the presence of at least one.

[0035] In this embodiment, as Figure 1-5 As shown, a robot packaging box is disclosed, including a box body 2 with an opening at the top and a cover 1 that can close the opening. The box body 2 has a charging area 3, which is configured to house a charging device. A positioning element 11 is installed on the cover 1, and it can switch between a transport posture and a charging posture by changing its relative position to the box body 2. In the transport posture, the cover 1 closes onto the opening, forming a storage space for loading the robot around the box body 2. In the charging posture, the cover 1 is vertically connected to the box body 2, making the positioning element 11 visible to guide the robot into the charging area 3. Thus, by switching the cover between the transport and charging postures, the packaging box not only fulfills traditional storage and transportation functions but can also be used as a charging facility after the robot has finished its work, avoiding idleness and improving resource utilization. The charging area inside the box can house the charging device, and the positioning element can be installed by raising the cover, eliminating the need for a separate charging device on the ground. The box body also provides some protection for the internal charging device.

[0036] In this embodiment, as Figure 6As shown, the packaging box also includes an upper liner 5, grounding rollers 21, and support members 22. Multiple grounding roller positioning grooves 12 are provided near the upper surface of the upper cover 1, their specific positions corresponding to the grounding rollers 21. The grounding rollers 21 can be omnidirectional wheels. Multiple support members 22 can be provided along the width direction at the bottom of the box body 2. The grounding rollers 21 can be connected to the grounding roller positioning grooves 12. By connecting the grounding rollers 21 and the positioning blocks, two or more packaging boxes can be stacked, saving storage space. The positioning grooves also improve the stability during stacking and prevent accidents.

[0037] In this embodiment, as Figure 5 As shown, the top of the upper pad 5 is provided with a placement slot. In this embodiment, a robot remote control terminal placement slot 51, a charger placement slot 52 and an extension placement slot 53 are provided to organize and store the remote control terminal, charger and other extension components of the quadruped robot 4, so as to avoid the situation that the components are easily lost due to too many components.

[0038] In this embodiment, as Figure 12 As shown, the charging area 3 can be composed of a lower end pad or it can be directly on the bottom plate of the housing. A through hole for accommodating the charging device 35 is provided in the center of the charging area 3, and the through hole is also used to fix the charging base 34.

[0039] In this embodiment, at least one positioning element 11 is installed on the inner side of the upper cover 1. When in the charging posture, the upper cover 1 is vertically connected to one side of the housing 2, and the positioning element 11 is higher than the housing 2 and faces towards the opening. Two positioning elements 11 are installed side by side along the length direction on the inner side of the upper cover 1. The positioning element 11 is a long strip-shaped positioning plate. The box 2 has an openable and closable side door 23 that allows the robot to enter and exit autonomously. When in the charging posture, the upper cover 1 is vertically connected to the side of the box 2 away from the side door 23, and the positioning component 11 is higher than the box 2 to guide the robot to enter the charging area 3 through the side door 23.

[0040] In this embodiment, as Figure 9 As shown, the two positioning elements 11 can be reflectors and / or positioning codes. The positioning elements 11 are arranged parallel to each other along the length direction on the inner side of the upper cover 1 near the cover edge in the width direction. The spacing between the positioning elements 11 is equal to the spacing between the guide elements 33. In this way, when the quadruped robot 4 is charging and positioning, the spacing between the positioning elements 11 can be obtained by the sensing element 43, and the spacing between the four legs can be adjusted by the spacing between the positioning elements 11 to align with the guide elements 33, which helps to improve the accuracy and convenience of the quadruped robot 4 charging and positioning.

[0041] In this embodiment, as Figure 7As shown, the box 2 also includes an uphill guide 32, which has a guide portion 321 for the robot's feet to step on; the bottom of the side door 23 is hinged to the box 2 and can be flipped downwards to open the robot's entry channel; the uphill guide 32 is connected to the inside of the side door 23 and can rotate downwards with the side door 23 to one side of the box 2, so that the guide portion 321 is located above the ground for the robot to step on and enter the box 2. Specifically, the side door 23 is hinged to the bottom of the box 2 and can be flipped downwards to form a channel for the quadruped robot 4 to enter the packaging box, the uphill guide 32 is the side door 23, and the guide portion 321 is a ramp set at the bottom of the side door 23.

[0042] In another embodiment, such as Figure 8 As shown, the side door 23 can be hinged to the box 2 and rotated to one side to open the robot's entry channel; the ramp guide 32 can detach from the box 2 and be fixed to one side of the box 2, so that the guide part 321 is located above the ground for the robot to step on and enter the box 2. Specifically, side rollers can also be added to the bottom of the side door 23, which can be used to open from one side of the box and place the ramp guide inside the box above the ground for the robot to step on and enter the box. The uphill guide 32 can be a detachable pad. The bottom of the uphill guide 32 is provided with an extension block 323 along the flat direction. The height of the extension block 323 is lower than the height of the bottom plate of the box. It can be used to fix the uphill guide in the space between the bottom of the box and the ground. The uphill guide 32 is provided with an end abutment pad 322 in the middle, which can be used to provide abutment for the head of the robot dog when it is packed. The uphill guide 32 is provided with guide parts 321 on both sides. The height of the guide parts 321 is lower than the height of the bottom plate of the box, so as to form a step for the robot dog to step into the box.

[0043] In this embodiment, as Figure 9 As shown, the upper cover 1 also includes multiple housing connectors 14. When in the charging position, the cover edges at both ends of the upper cover 1 in the width direction are connected to the outside of the housing 2 via the housing connectors 14. Specifically, as... Figure 9 As shown, the housing connector 14 can be a locking structure, specifically a strip-shaped locking structure. The locking buckle is located on the outer edge of the cover 1 along its length, and the locking hook is located on the surface of the housing 2 along its length. Other connecting components can also be used. In the charging posture, the cover 1 is locked to the housing 2 via the housing connector 14, always remaining perpendicular to the housing 2. This ensures that the positioning component 11 remains visible and does not move relative to the housing 2, guaranteeing that the quadruped robot 4 can continuously identify the positioning component 11 for charging positioning, thus improving the stability of charging positioning.

[0044] In this embodiment, as shown in the appendix Figure 10-13As shown, a charging base 34 is installed in the charging area 3 inside the housing 2. The charging base 34 is provided with a charging electrode assembly 342 that matches the position of the charging interface 44 on the robot's abdomen. The charging electrode assembly 342 can be connected to an external power source through a power cord.

[0045] Specifically, the charging area 3 also includes a charging base 34 and a front end pad 31. The charging base 34 is higher than the charging area 3. The charging base 34 has one or more protrusions forming a charging positioning part 341. The charging positioning part 341 near the front of the quadruped robot 4 is the tallest of all the protrusions. The charging positioning part 341 can restrict the position of the quadruped robot 4's abdomen when adjusting from a standing posture to a crawling posture during charging positioning, so as to ensure the correct docking of the charging interface 44 and the charging electrode assembly 342 and improve the stability of charging. The charging electrode assembly 342 is a pair of metal cylinders, protruding and arranged side by side on both sides of the center of the charging base 34, in contact with the charging interface 44, and connected to the charging device 35 at the bottom through a conductive wire. The bottom of the charging base 34 has a cavity to accommodate the charging device 35. The front end pad 31 is located on the inner side of the box surface of the housing 2, away from the side door 23, along the width direction. The front end pad 31 has a groove that makes close contact with the front head of the quadruped robot 4, providing flexible protection for the front head, improving stability and safety during storage and handling, extending the lifespan of the quadruped robot, and saving costs. The corresponding charging interface 44 is a circular electrode plate located on the abdomen of the quadruped robot 4; the circular shape increases the contact area and improves charging efficiency.

[0046] In this embodiment, two guide members 33 are arranged side by side at the bottom of the housing 2, and the charging base 34 is arranged between the two guide members 33. The robot can move along the guide members 33 to the top of the charging base 34. Specifically, the two guide members 33 can be two V-shaped guide grooves or U-shaped guide grooves respectively arranged on both sides of the charging base 34, and the guide members 33 are arranged along the length of the housing 2. They play a role in precise positioning and guidance. Through the cooperative guidance mechanism of the guide grooves and positioning members, the robot can achieve precise docking by blind operation, which improves the charging success rate. The guide members 33 can be set in the charging area and run through the length direction. Anti-slip material can be laid in the guide groove of the guide member 33 to prevent slippage and improve the stability of the quadruped robot when entering the housing and positioning for charging.

[0047] In this embodiment, a heat dissipation device can be arranged at the bottom of the housing 2 corresponding to the charging area 3. The heat dissipation device includes an air guide channel 27 and a fan arranged within the air guide channel 27. The air guide channel 27 connects the inside of the charging base 34 and the outside of the housing 2. Specifically, several heat dissipation vents 25 can be arranged side by side on both sides of the center of the housing bottom plate 26. The housing bottom plate 26 is provided with grooves corresponding to the positions of the heat dissipation vents 25 to form the air guide channel 27. The cavity of the charging base 34 is located directly above the area formed by each heat dissipation vent 25, so that the cooling fan 24 can remove the heat generated by the charging device 35 during charging to the greatest extent, thereby protecting the charging device 35 and improving the safety and stability of charging. The charging device 35 is a power adapter that receives AC current from an external power source and outputs DC current to the quadruped robot battery and the cooling fan.

[0048] In this embodiment, a grounding roller 21 is installed at the bottom of the housing 2. The grounding roller 21 has a metal latch, which is connected to the grounding terminal of the charging circuit in the charging base 34 through a wire and can contact the ground when in the charging posture.

[0049] When the packaging box is in the transport posture, the metal latch is open, and the grounding roller 21 can move freely, which facilitates the transport of the quadruped robot 4; when the packaging box is in the charging posture, the metal latch is locked, and the metal latch contacts the ground to form a grounding circuit, which improves the safety of the packaging box and the charging process.

[0050] In another embodiment, the charging base arranged in the charging area can be in a high position, i.e., at a set height from the bottom of the box. This set height allows the quadruped robot to lie on the charging base in a semi-squatting posture. This allows the quadruped robot to be placed in a semi-squatting position, with its midsection resting on the charging base, which provides support to its lower body. This keeps the robot in a semi-squatting posture and securely fixed inside the packaging box, allowing it to be packed without needing to adjust its posture after squatting, thus improving packing speed and convenience.

[0051] In another embodiment, an autonomous charging system is also disclosed, including a robot packaging box and a mobile robot as described in any of the foregoing embodiments; when the upper cover is in a transport posture, the robot can be loaded and wrapped inside the robot packaging box; when the upper cover is in a charging posture, the robot can be guided to the charging area inside the box by recognizing the positioning element on the upper cover and connect to the charging device to perform charging operations. The mobile calculator may be an optional accessory. Figure 9 and 13 Similar to quadruped robots or other multi-legged robots, humanoid robots or other mobile unmanned vehicles can also be selected.

[0052] In this embodiment, the mobile robot can be configured to obtain the position of the box by recognizing the positioning parts on the upper cover, and generate a charging path based on the box position and the current robot position; after entering the box according to the charging path, it moves to the charging area according to the guide groove on the box to complete the docking with the charging device, and starts charging after receiving the docking completion information.

[0053] In this embodiment, when a quadruped robot is selected as the mobile robot, a power switch 41 can be provided on the side of the rear head of the quadruped robot 4, and a charging indicator light 42 can be provided on the top of the rear head. When the quadruped robot 4 needs to be stored, the metal latches of the grounding rollers are fastened, the side door 23 is opened, the ramp guide 32 is set up, and the quadruped robot 4 is operated by the remote terminal to walk to the front of the packaging box. The positioning method is started, the quadruped robot 4's sensing element 43 scans the positioning element 11, the distance between the four legs is adjusted, and it drives into the packaging box through the box entry channel. When the quadruped robot needs to be transported, the metal latches of the grounding rollers of the packaging box are opened, the side door is closed and locked, the ramp guide is fixed to the rear head of the quadruped robot, the upper pad and the upper cover are placed on the upper part of the box and locked, and the transportation can begin. When the quadruped robot is in the charging state, the charging indicator light can indicate the charging status or charging failure through color and flashing frequency. This allows a single person to complete the packaging, storage, and charging of the quadruped robot. By combining the packaging box and charging station, costs are saved, space is reduced due to discarded packaging boxes, and the problem of resource waste caused by non-reusable packaging boxes is solved.

[0054] In another embodiment, as shown in the appendix Figure 14 As shown, a charging method is also disclosed, which can use the robot packaging box disclosed in the foregoing embodiments. The charging method specifically includes the following steps: Step S1: Fix and ground the housing, vertically connect and fix the upper cover to the housing to switch to the charging posture, so that the positioning components arranged inside the housing are visible outside the housing.

[0055] In step S2, after receiving the charging command, the robot identifies the position of the positioning component through sensors and generates a movement path to enter the charging area inside the box by identifying and tracking the positioning component.

[0056] Step S3: After the robot enters the charging area along the moving path, it performs a preset charging action to complete the docking with the charging device and begins the charging operation.

[0057] Specifically, this embodiment uses a quadruped robot as an example, but other types of robots can also be used. Before the quadruped robot needs to charge autonomously, open and remove the top cover of the packaging box, open the side door, and remove the top padding and set it aside. Open the top cover and connect it to the box body through the box body connector. The box cover is designed with a positioning code for the robot dog to identify charging. Flip the flip-top cover connected to the lower box body to the ground contact state. The inside of the flip-top cover is equipped with a ramp to facilitate the robot dog's entry and exit from the box body. When the packaging box is used as a charging station, the grounding roller needs to be locked with a metal latch to prevent the robot dog from shifting its position when entering and exiting the lower box body. At the same time, the grounding roller is connected to the ground through its own metal latch. The grounding roller is also grounded with the box body's charging electrodes inside the box body to prevent safety hazards in case of leakage. When the robot dog is charging, it identifies the positioning code on the box cover through the sensing positioning device, thereby realizing the robot dog's automatic charging positioning function.

[0058] When the quadruped robot enters the packaging box for charging, the abdominal electrode at the bottom of the quadruped robot connects with the charging electrode contacts on the charging base to complete the charging process.

[0059] When the quadruped robot enters the packaging box for charging, the robot can observe whether charging is complete or whether a charging malfunction has occurred through the charging status indicator lights. This realizes the function of combining the packaging box and the charging station, saving users purchase costs and overcoming the problems of traditional robot packaging boxes having a single function, only used for transportation protection, and the packaging box being discarded or idle after unpacking, resulting in resource waste; while charging stations are often set up separately, requiring robots to be equipped with additional dedicated charging stations, which occupy space and increase costs.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.

[0061] In summary, the above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made within the scope of the claims of the present invention should be covered by the present invention.
