Description

Technical Field

[0001] This disclosure relates to the field of delivery robot technology, and in particular to a delivery robot with warehouse cleaning function. Background Technology

[0002] The rapid and advanced development of sensors and 5G technology has led to the rapid advancement of unmanned delivery robots. These robots are widely used in restaurant delivery, outdoor food delivery, and courier services. While robots typically have radar installed at the front of their path for obstacle avoidance, the radar's detection range is often obstructed by the robot itself, limiting its detection to obstacles only in front of the robot's direction of movement and preventing 360° obstacle avoidance. This makes the robot prone to collisions. To address this issue, current delivery robots utilize a protruding lidar unit on the top surface of the delivery robot's housing, away from the self-propelled chassis. This protrudes the lidar's detection range, ensuring 360° obstacle avoidance and improving both efficiency and user experience.

[0003] However, in actual use, it has been found that current intelligent delivery robots cannot automatically clean the warehouse after use, especially in hotel scenarios. Since the delivered goods include beverages or meals, food residues or stains will remain in the warehouse, requiring manual wiping and cleaning before delivery. Therefore, the automation level of delivery robots needs to be improved. Summary of the Invention

[0004] The purpose of this disclosure is to provide a delivery robot with a warehouse cleaning function to solve the technical problem that in the prior art, because the delivered goods include beverages or meals, food scraps or stains will remain in the warehouse, requiring manual wiping and cleaning of the warehouse before delivery, and the degree of automation and delivery efficiency of the delivery robot need to be improved.

[0046] like Figure 1 and Figure 2 As shown, a through hole is provided between the two sets of cargo compartments 11, and a water outlet pipe 32 passes through the through hole. A water inlet is provided on the top of the water tank 31, which is used to replenish the water tank 31 with liquid for cleaning the cargo compartments 11.

[0047] like Figure 3 and Figure 5 As shown, a drain outlet 13 that runs through the side of the cargo compartment 11 is provided on one side of the pull-out cavity 12. A guide surface 14 for guiding sewage discharge is provided at the bottom of the drain outlet 13. The guide surface 14 is a rounded slope.

[0048] like Figure 5 As shown, a guide hole 16 penetrating the robot body 1 is opened on the side of the pull-out cavity 12 away from the drain outlet 13, and there are two guide holes 16 in each group; as shown Figure 1 As shown, the cable 79 passes through the guide hole 16 and is slidably disposed with respect to the inner wall of the guide hole 16. The cable 79 is located behind the sewage box 2, and the guide hole 16 is used to guide the cable 79 when it is pulled.

[0049] like Figure 4 As shown, the top of the sewage box 2 is connected to a handle 21. Two sets of sewage inlets 22 are opened on one side of the sewage box 2, which are respectively corresponding to two sewage outlets 13. The sewage inlets 22 are fitted with the sewage outlets 13 to collect sewage fully. The back of the pull-out cavity 12 is also connected to a drain outlet to discharge the sewage remaining in the pull-out cavity 12.

[0050] As shown in the figure Figure 5 As shown, each cargo compartment 11 has a guide groove 15 on its inner back side wall. The back of the second connecting block 710 is connected to the guide block 711. The guide block 711 is located in the guide groove 15 and is limited to slide. The cross-section of the guide groove 15 and the cross-section of the guide block 711 are both "T" shaped structures.

[0051] like Figure 5 and Figure 6 As shown, a spring 715 is connected to one side of the second connecting block 710, and the other end of the spring 715 is fixedly connected to the inner side wall of the cargo compartment 11. The spring 715 is provided to exert a certain restoring pull on one end of the cable 79 while the connecting plate 76 is moving back to its original position, so that the scraper 713 is reset.

[0052] like Figure 6 As shown, a movable hole 714 is provided on the fixed frame 71, and a fixed rod 712 is connected to the bottom of the second connecting block 710. The fixed rod 712 passes through the movable hole 714, and the bottom end of the fixed rod 712 is fixedly connected to the scraper 713. The diameter of the fixed rod 712 is smaller than the slot width of the movable hole 714, and the fixed rod 712 is slidably set along the inner wall of the movable hole 714.

[0053] One end of the lead screw 73 that passes through the fixed frame 71 is connected to the servo motor 72. The servo motor 72 is detachably connected to the back side wall of the cargo compartment 11 by bolts. After each time goods are taken out of the cargo compartment 11, the sensor detects that there are no goods and sends a start command to the control terminal of the servo motor 72 to start the servo motor 72 and the rinsing assembly 3.

[0054] like Figures 1 to 6 As shown, the side of the scraper 713 that is close to the connecting plate 76 is a pointed cone shape for scraping against the bottom wall of the cargo compartment 11. The height of the connecting plate 76 relative to the bottom inner wall of the cargo compartment 11 is higher than that of the scraper 713. The height relationship between the connecting plate 76 and the scraper 713 is set to avoid motion interference between the connecting plate 76 and the scraper 713.

[0055] Working principle: After each delivery by the robot body 1, the sensor installed in the cargo compartment 11 detects the absence of cargo weight and sends a command to the control terminals of the water pump and servo motor 72 in the rinsing assembly 3, activating them according to a pre-set start sequence. The water pump discharges cleaning liquid from the water tank 31 through the nozzle 34 to rinse the bottom wall of the cargo compartment 11. After rinsing, the servo motor 72 starts, rotating the lead screw 73. Under the limiting guidance of the guide rod 74 and the driving action of the lead screw 73, the connecting seat 75 moves horizontally along the fixed frame 71, thereby moving the connecting plate 76 from the side near the drain port 13 towards the rinsing assembly 3. The plastic brush connected to the bottom of the connecting plate 76 cleans the bottom inner wall of the cargo compartment 11. Due to the spraying of cleaning liquid, the stains are soaked, allowing them to be easily cleaned by the plastic brush at the bottom of the connecting plate 76. Simultaneously with the movement of the connecting plate 76 and the connecting seat 75, the support plate 77 and the first connecting block 78 connected to the top of the connecting seat 75 move synchronously. As the connecting block 78 moves closer to the rinsing assembly 3, one end of the cable 79 is pulled, causing the cable 79 to pull along the guide hole 16 and the other end to pull the second connecting block 710 in the opposite direction to the movement of the connecting plate 76, guided by the guide block 711 and the guide groove 15. Simultaneously, the fixing rods 712 and 173 move relative to the connecting plate 76. Since the scraper 713 is located below the connecting plate 76 and the plastic brush is a soft brush, the movement of the connecting plate 76 and the scraper 713... The robot's movement is undisturbed. The scraper 713 scrapes against the bottom inner wall of the cargo compartment 11, effectively removing stubborn stains and thoroughly cleaning them. The scraper 713 also pushes wastewater along the guide surface 14 into the drain outlet 13. Since a wastewater box 2 is located on one side of the drain outlet 13, the wastewater is collected in the wastewater box 2. Periodically, the wastewater box 2 is pulled out by pulling the handle 21 to empty the wastewater. A drain outlet is also located on the back of the pull-out cavity 12 to drain any remaining wastewater. After cleaning, the cargo compartment 11 is reset and ready for the next transport. The robot body 1 boasts high turnover efficiency, cleanliness, and practicality.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure, and are not intended to limit them. Although this disclosure 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 or all of the technical features therein. Such 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 this disclosure.
