[0035] Please see Figures 1 to 4 This embodiment provides a delivery robot, including: a body 1, a linear motion mechanism 2, and a push plate 3;

[0036] The main body 1 is equipped with a storage compartment 11 for storing express packages and a controller 4;

[0037] The linear motion mechanism 2 is located inside the storage cavity 11 and is connected to the controller 4;

[0038] The push plate 3 is mounted on the linear motion mechanism 2 and moves linearly under the drive of the linear motion mechanism 2 to push the express delivery stored in the storage cavity 11 out of the storage cavity 11.

[0039] It should be noted that "body 1" refers to the main structure of the delivery robot, which bears the overall load-bearing function. The bottom of body 1 is equipped with drive wheels and a steering mechanism, controlled by controller 4, enabling autonomous movement, turning, and obstacle avoidance. Body 1 houses a power system (such as a lithium battery pack) to provide power to controller 4, linear motion mechanism 2, walking motors, communication modules, etc. Controller 4 is responsible for processing sensor data, performing path planning, receiving remote commands, and controlling the movement of pusher 3 to achieve automated operation.

[0040] It should be noted that the linear motion mechanism 2 is a component capable of linear reciprocating motion. It receives drive signals from the controller 4 to start or stop. When it is necessary to retrieve a package from the storage cavity 11, the controller 4 controls the corresponding linear motion mechanism 2 to move, driving the push plate 3 forward and pushing the target package out of the storage cavity 11. The target package falls to the ground for the user to retrieve.

[0041] Unlike existing technologies, the above-mentioned technical solution can complete the delivery action without anyone being present. The delivery robot pushes the package to the designated location through the linear motion mechanism 2, and the user can then pick it up at any convenient time without having to synchronize with the delivery process, which significantly improves the flexibility of delivery.

[0042] Please see Figure 2 and Figure 3 In some embodiments, the linear motion mechanism 2 includes a linear guide rail 21 with a linearly movable slider 22. A push plate 3 is mounted on the slider 22 and moves along with it. When the controller 4 receives a push command, a drive signal is transmitted to the linear motion mechanism 2, and the slider 22 moves in a directional linear motion. Since the push plate 3 is connected to the slider 22, it moves forward synchronously, pushing the express package out of the storage cavity 11. After the push action is completed, the slider 22 returns to its original position, and the push plate 3 also resets, ready for the next operation.

[0043] Preferably, the linear motion mechanism 2 uses a lead screw and nut transmission to achieve the linear movement of the slider 22. Specifically, the motor drives the lead screw to rotate, and the lead screw and nut form a transmission relationship through a threaded engagement; the slider 22 is fitted onto the nut and forms a sliding guide engagement with the guide rail through a linear groove, thereby converting the rotational motion of the lead screw into the reciprocating linear motion of the slider 22 along the guide rail. The push plate 3 is firmly connected to the slider 22 by bolts or other fasteners and moves synchronously with the slider 22 to realize the pushing action of the express delivery in the storage cavity 11.

[0044] In some embodiments, the linear motion mechanism 2 may be a hydraulic cylinder, a pneumatic cylinder, or the like.

[0045] In some embodiments, the linear motion mechanism 2 further includes a linear bearing 23, which is mounted on the storage cavity 11 and connected to the push plate 3 via a connecting shaft. The linear bearing 23 and the linear guide rail 21 are arranged in the same direction, jointly constraining the motion freedom of the push plate 3, allowing it to move linearly only along the depth direction of the storage cavity 11. This depth direction is generally consistent with the front-rear direction of the body 1, and the storage cavity 11 extends to the front of the body 1, facilitating smooth ejection from the front. When the linear motion mechanism 2 drives the slider 22 to move, the push plate 3 moves accordingly and is guided by the linear bearing 23 during the movement, effectively preventing path deviation caused by uneven force and ensuring the linearity and stability of the motion trajectory.

[0046] Please see Figure 2 and Figure 3 In some embodiments, there are two linear bearings 23, which are symmetrically arranged on both sides of the push plate 3. Optionally, the two linear bearings 23 are respectively installed on the left and right sides of the push plate 3 in the storage cavity 11, and each linear bearing 23 is provided on a connecting shaft that mates with it. The connecting shaft is arranged horizontally along the front and rear direction of the machine body 1 and is parallel to the linear guide rail 21.

[0047] Please see Figure 1 and Figure 4 In some embodiments, the delivery robot also includes a sliding mechanism 24, which is located on the bottom of the storage cavity 11, on the bearing surface of the delivery placement area. When the delivery is stored, the bottom surface of the delivery directly contacts the surface of the sliding mechanism 24; when the push plate 3 pushes the delivery to move, relative sliding occurs between the delivery and the sliding mechanism 24, effectively reducing the motion resistance when the delivery is pushed out.

[0048] Please see Figure 1 and Figure 4 Preferably, the sliding mechanism 24 is a roller mechanism. The roller mechanism includes multiple rotatable rollers distributed along the express delivery movement path at the bottom of the storage cavity 11. The rollers are mounted on the bottom of the storage cavity 11 via a pivot and protrude to contact the express delivery. The rollers combine wear resistance, shock absorption, and low noise characteristics, making them suitable for automated delivery scenarios with frequent start-stop operations.

[0049] Please see Figure 1 and Figure 4 In some embodiments, the roller mechanism includes at least two sets of roller groups 25, arranged side by side. Each set of roller groups 25 includes multiple rollers spaced apart along the delivery direction, and the multiple sets of roller groups 25 are arranged in parallel to form a multi-row rolling support structure. When the package is placed into the storage cavity 11, its bottom surface spans across the at least two sets of side-by-side roller groups 25, achieving multi-point support.

[0050] In some embodiments, the sliding mechanism 24 may employ a slider structure made of a low-friction material, such as a material with self-lubricating or low-friction properties, such as polytetrafluoroethylene (PTFE), nylon (PA), polyoxymethylene (POM), or stainless steel cladding.

[0051] In some embodiments, the robot body 1 is also equipped with a camera, which is connected to the controller 4. The camera can be installed in a visible position, such as the front, top, or side of the robot body 1, facing the outlet of the storage cavity 11 or the working area in front of the robot. The camera can acquire image or video information in real time and transmit the data to the controller 4 for processing. The camera can take photos of the package at a designated location and then upload them to the platform for delivery to the user. The camera can also be used by the robot to obtain information about its surrounding environment to enable driving and obstacle avoidance functions.

[0052] In some embodiments, the housing 1 is further provided with an electric cabinet door, which is located in the storage cavity 11 and connected to the controller 4, for closing or opening the retrieval port of the storage cavity 11. The electric cabinet door may adopt a flip-type, sliding, or double-opening structure, and is automatically opened and closed by a servo motor or stepper motor.

[0053] The control logic of this application is as follows:

[0054] Delivery robots are suitable for indoor and outdoor two-wheeled or multi-wheeled delivery. When customers are unable to pick up their packages in person, they have the ability to deliver the packages to the locations designated by the customers.

[0055] The courier loads the package at the courier station (the robot's starting point) and operates the robot to the designated location (the customer's delivery address). When the robot arrives at the location, the main controller opens the cabinet door and controls the stepper motor controller to push out the push plate, placing the package out of the cabinet and onto the ground.

[0056] After the package is delivered to the designated location, the robot's built-in camera takes a picture of the package at the designated location and uploads it to the platform so that it can be sent to the customer.

[0057] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
