[0038] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.
[0039] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0040] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0041] Reference Figures 1 to 7 As shown, this utility model provides a wheeled service robot with expandable functions, including a wheeled chassis 1, a height adjustment module 2 disposed on the top of the wheeled chassis 1, an expansion application module 3 disposed on the height adjustment module 2, and a connection module 4 connecting the height adjustment module 2 and the expansion application module 3; the height adjustment module 2 is used to drive the connection module 4 to move the expansion application module 3 up and down to adjust the height.
[0042] Connecting module 4:
[0043] The connection module 4 includes a connection block 41 connected to the height adjustment module 1 and a connection seat 42 connected to the extended application module 3; the connection block 41 and the connection seat 42 are detachably connected. Furthermore, the connection module 4 also includes a locking and fixing component 44; the rear end face of the connection seat 42 has a slot 43 into which one end of the connection block 41 can be inserted; when the connection block 41 is inserted into the slot 43 of the connection seat 42, the locking and fixing component 44 is used to lock and fix the connection seat 42 and the connection block 41.
[0044] The connecting module 4 ensures a secure connection between the height adjustment module 2 and the extended application module 3 (such as the screen module, robotic arm, etc.). The plug-in structure of the connecting module 4 allows the extended application module 3 to be quickly fixed or disassembled, simplifying the structure of the service robot and the replacement process of the extended application module 3.
[0045] Specifically, the locking and fixing component 44 includes screws and nuts. One end of the connecting block 41 is fixed to the lifting slider 24, and the other end is inserted into the slot 43 of the connecting seat 42. The connecting block 41 and the connecting seat 42 are completely fixed by screws and nuts. The expansion application module 3 is installed on the connecting seat 42, and the structural design of the connecting seat 42 is adapted to the expansion application module 3. When the expansion application module 3 needs to be replaced, the connecting seat 42 is replaced together.
[0046] Furthermore, the slot 43 of the connector 42 is designed as a U-shaped slot, and correspondingly, the connector 41 is also designed as a U-shaped structure. By making the connector 41 a hollow structure, the weight of the connector module 4 can be reduced, the height adjustment accuracy of the extended application module 3 can be improved, and the production cost of the service robot can be reduced.
[0047] Charging station 5:
[0048] The service robot also includes a charging pile 5, which is designed separately from the wheeled chassis 1. The charging pile 5 has a charging port 51, and the wheeled chassis 1 has charging contacts 13 that match the charging port 51. The charging pile 5 has several infrared transmitters 6, and the front and rear of the wheeled chassis 1 each have several infrared receivers 7 that correspond one-to-one with the infrared transmitters 6. By setting up the charging pile 5 and the infrared transmitters 6 and infrared receivers 7, the service robot can achieve automatic recharging. Specifically, the charging pile 5 has three infrared transmitters 6, which are used to transmit coded infrared guidance signals to guide the wheeled chassis 1 in positioning and navigation. The charging pile 5 has a charging port 51. Correspondingly, the front and rear of the wheeled chassis 1 each have three infrared receivers 7 to receive the infrared guidance signals emitted by the charging pile 5. The wheeled chassis 1 completes automatic positioning based on the infrared guidance signals and connects with the charging port 51 of the charging pile 5 through the charging contacts 13 designed on the wheeled chassis 1 to complete the charging docking.
[0049] Extended Application Module 3:
[0050] Service robots can have their functional modules replaced and upgraded according to different task requirements.
[0051] Example 1:
[0052] The extended application module 3 includes a screen module 31 and a first pitch angle adjustment module 32 disposed between the screen module 31 and the connector 42. The first pitch angle adjustment module 32 includes a first rotation shaft hinged to the connector 42 and a first pitch drive motor for driving the first rotation shaft to pitch to adjust the angle of the screen module 31.
[0053] The screen module 31 has a built-in camera. The real-time images captured by the camera are transmitted to the service robot's processor. The processor controls the wheeled chassis 1, the height adjustment module 2, and the first pitch angle adjustment module 32 to perform actions. Controlling the service robot's actions can be compared to adjusting a person's posture, such as standing / squatting and looking up / down. The screen module 31 is used to display information, provide interactive services, or perform question-and-answer tasks.
[0054] The screen module 31 is mounted on the connecting block 41 via the first rotating shaft, and the screen module 31 performs a pitching motion under the control of the first pitch drive motor.
[0055] Example 2:
[0056] The extended application module 3 includes a robotic arm 33 mounted on the front end of the connecting base 42, a binocular camera 34 mounted on the top of the connecting base 42, a second pitch angle adjustment module 35 located between the binocular camera 34 and the connecting base 42, and a monocular camera located on the wrist of the robotic arm 33. The second pitch angle adjustment module 35 includes a second rotating shaft hinged to the connecting base 42, and a second pitch drive motor for driving the second rotating shaft to pitch to adjust the angle of the binocular camera 34.
[0057] The binocular camera 34 can achieve pitch movement via the second pitch angle adjustment module 35. The monocular camera is mounted on the wrist of the robotic arm 33. By combining the global field of view of the binocular camera 34 with the local field of view of the monocular camera, the service robot can perceive more comprehensive information. The real-time images captured by the binocular camera 34 and the monocular camera are transmitted to the service robot's processor, which controls the wheeled chassis 1, the height adjustment module 2, the second pitch angle adjustment module 35, and the robotic arm 33 to perform actions. The robotic arm 33 is used to perform more complex tasks, such as handling, cleaning, and gripping.
[0058] Meanwhile, the binocular camera 34 can also be used for visual perception in the automatic recharging function.
[0059] It is worth noting that the screen module 31 in Embodiment 1 and the robotic arm 33 in Embodiment 2 are only two embodiments of the extended application module, but are not limited to the application scope of these two embodiments.
[0060] Wheeled chassis 1:
[0061] The wheeled chassis 1 includes a base 11 and four omnidirectional wheels 12 located at the bottom of the base 11; the height adjustment module 2 is located at the top of the base 11. Equipped with four omnidirectional wheels 12, each wheel has two motors controlling direction and speed, enabling free movement in multiple directions, including forward, backward, turning, and lateral translation. This allows the service robot to maneuver flexibly in complex environments, providing higher mobility and precise positioning capabilities. Furthermore, the front of the base 11 is equipped with an audio module 8 and a microphone array, enabling voice operation prompts, task completion notifications, and fault alarms, optimizing the interactive experience between the service robot and the user.
[0062] Height adjustment module 2:
[0063] The height adjustment module 2 includes a lifting slide rail 21 and a lead screw assembly 22 mounted on the top of the wheeled chassis 1, a lifting drive component 23 driven by the lead screw assembly 22, and a lifting slider 24 connected to the lead screw assembly 22; the connecting block 41 is detachably connected to the lifting slider 24; the lifting drive component 23 is used to drive the lead screw assembly 22 to move the lifting slider 24 up and down along the lifting slide rail 21.
[0064] Furthermore, the height adjustment module 2 also includes a mounting bracket with an inner cavity. The lifting slide rail 21, lead screw assembly 22, lifting drive component 23, and lifting slider 24 are all mounted within the inner cavity of the mounting bracket. The mounting bracket has three grooves in the vertical direction, with the two side grooves for one end of the connecting block 41 to pass through and connect with the lifting slider 24, and the middle groove for extending the electrical connection for data interaction between the application module 3 and the service robot's processor.
[0065] The lifting slide rail 21 is fixed to the base 11 with screws, and the lifting slider 24 is fixed to the nut of the lead screw assembly 22. Specifically, the lifting drive component 23 is a lifting drive motor, which is installed on the top of the lead screw assembly 22. It can control the lifting slider 24 to move up and down along the lifting slide rail 21, thereby mimicking the squatting / standing posture of a human body. This allows the service robot to automatically adjust its working height when performing tasks, adapt to different operating spaces, and improve the accuracy and flexibility of operation.
[0066] The robot body, consisting of a shared wheeled chassis 1, height adjustment module 2, and connecting block 41, can be flexibly configured to meet different task requirements through combinations of the robot body and various extended application modules 3 (such as screen module 31 and robotic arm 33). Specifically, the robot body design is highly interchangeable; it can provide question-and-answer services by configuring the screen module 31, and perform complex tasks by configuring the robotic arm 33. This simplifies the service robot's structure, reduces costs, and improves its versatility and adaptability. Furthermore, the modular design allows users to quickly switch and upgrade according to actual needs, thereby extending the service robot's lifespan and multi-scenario applicability. It offers significant advantages in multi-functional expandability, modular design, and cost-effectiveness, meeting a wider range of service needs and enhancing the competitiveness of service robots in various fields.
[0067] This utility model provides a highly efficient and flexible wheeled service robot. Through shared core components and replaceable expansion application modules 3, it significantly improves the service robot's multifunctionality, flexibility, and autonomy, enabling it to adapt to multiple scenarios and task requirements.
[0068] 1. Functional expandability and flexibility: Through the modular design of the wheeled chassis 1 and the height adjustment module 2, as well as the detachable connection between the connecting block 41 and the connecting seat 42, the service robot can quickly replace the expansion application modules, such as the screen module 31 and the robotic arm 33, according to different task requirements, thereby completing a variety of tasks and improving the multifunctionality and flexibility of the service robot.
[0069] 2. Simplified structure and reduced cost: By sharing the wheeled chassis 1, height adjustment module 2, and connecting block 41, the overall structural design of the service robot is simplified, avoiding compatibility issues between different configurations and reducing manufacturing costs and complexity.
