[0030] The embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0031] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or may also have an intervening component. When a component is considered to be "placed" on another component, it can be directly placed on the other component or may also have an intervening component. The terms "top," "bottom," "upper," "lower," "left," "right," "front," "back," and similar expressions used in this article are for illustrative purposes only.

[0032] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0033] Please see Figures 1-6This application provides a mobile monitoring robot 100 capable of switching facial expressions, comprising: a housing 10, a contact plate 20, an expression display screen 30, and an expression integrated chip 40. The contact plate 20 is integrally formed with the housing 10. The contact plate 20 is located within the housing 10 and separately separates an expression display area 11 and a circuit board mounting area 12. The expression display screen 30 is located in the expression display area 11. The expression display screen 30 abuts against the contact plate 20. The expression integrated chip 40 is electrically connected to the expression display screen 30. The expression integrated chip 40 is located in the circuit board mounting area 12. The expression integrated chip 40 includes multiple expression packs. The expression integrated chip 40 is electrically connected to the expression display screen 30, and the expression display screen 30 can display any one of the expression packs.

[0034] Specifically, the shell 10 serves as the main structure of the robot, providing necessary protection and support. It not only protects the internal electronic components from damage by the external environment but also provides a stable physical foundation for the robot. The shell 10 is integrally formed with the abutment plate 20, ensuring the structural stability and integrity.

[0035] The abutment plate 20 is located inside the housing 10 and is tightly connected to the housing 10 by integral molding. The main function of the abutment plate 20 is to separate the expression display area 11 and the circuit board mounting area 12, ensuring that each component can work independently and efficiently.

[0036] The abutment plate 20 is integrally formed with the housing 10 and abuts against the expression display screen 30, providing stable support for the display screen. In addition, it maintains an appropriate distance from components (such as the expression integrated chip 40) within the circuit board mounting area 12 to ensure the reliability and safety of electrical connections.

[0037] The facial expression display screen 30, located in the facial expression display area 11, is a key component for visual interaction between the user and the robot. It can display a wide variety of facial expressions according to instructions provided by the facial expression integrated chip 40, thereby enhancing the robot's emotional expression capabilities.

[0038] The facial expression display screen 30 abuts against the abutment plate 20 and is electrically connected to the facial expression integrated chip 40. This connection method ensures that the display screen can accurately and timely receive the facial expression data sent by the chip and present it in a visual form.

[0039] The facial expression integrated chip 40 is one of the core components of the robot, containing various facial expression data. This facial expression data can be switched according to user commands or preset conditions and transmitted to the facial expression display screen 30 for display via electrical connection.

[0040] The expression integrated chip 40 is located within the circuit board mounting area 12 and is electrically connected to the expression display screen 30. Furthermore, the chip may also be connected to other control components (such as processors, memory, etc.) to achieve more complex functions and higher performance.

[0041] The integrated facial expression chip 40 provides the robot with a wealth of facial expression data. These expressions can be switched according to different scenarios and user needs, thereby enhancing the robot's interactivity and user-friendliness.

[0042] In one specific embodiment, the mobile monitoring robot includes a circuit board 50 located within the expression display area 11 and the circuit board mounting area 12. The expression integrated chip 40 is vertically connected to the circuit board 50, the expression display screen 30 is connected to the circuit board 50, and the abutment plate 20 abuts against the circuit board 50.

[0043] Specifically, circuit board 50, as the core component of the robot, is responsible for connecting and controlling various electronic components. Circuit board 50 not only connects the expression integrated chip 40 and the expression display screen 30, but may also connect other key components such as processors, memory, sensors, and power supplies to realize the overall function and performance of the robot.

[0044] The facial expression integrated chip 40 is vertically connected to the circuit board 50. This vertical connection helps save planar space on the circuit board 50, making the layout of the circuit board 50 more compact. At the same time, the vertical connection may also improve the stability and reliability of the electrical connection, because vertical insertion generally has better resistance to vibration and insertion / removal forces.

[0045] Vertical connectivity ensures that the expression integrated chip 40 can efficiently and accurately transmit signals with other components on the circuit board 50, which is crucial for achieving rapid switching and accurate display of expressions.

[0046] The facial expression display screen 30 is connected to the circuit board 50 via appropriate electrical connectors (such as flexible circuit board 50, connectors, etc.). This connection ensures that the display screen can receive signals from the facial expression integrated chip 40 and convert them into visual facial expression images.

[0047] The reliable connection between the expression display screen 30 and the circuit board 50 enables the expression display screen 30 to display the expression data sent by the expression integrated chip 40 in real time and accurately, thereby enhancing the robot's interactivity and user-friendliness.

[0048] The abutment plate 20 abuts against the circuit board 50 to ensure the stable installation of the circuit board 50. As a structural component within the housing 10, the abutment plate 20 provides necessary support and protection for the circuit board 50, preventing loosening or damage to the connection due to vibration or impact.

[0049] In one specific embodiment, the mobile monitoring robot includes a gold finger 60, one end of which is connected to the expression display screen 30, and the other end of which is plugged into the circuit board 50.

[0050] Specifically, one end of the gold finger 60 is connected to the expression display screen 30. The connection between the gold finger 60 and the expression display screen 30 is achieved through soldering, plugging, or other suitable electrical connection methods. The gold finger 60 ensures good stability and reliability of the electrical connection with the expression display screen 30.

[0051] The connection to the expression display screen 30 allows the gold finger 60 to receive signals from the expression display screen 30, which may include display commands, image data, etc. Through the transmission of the gold finger 60, these signals can be efficiently transmitted to the circuit board 50 for processing and display.

[0052] The other end of the gold finger 60 is inserted into the circuit board 50. This insertion method typically has a self-locking or locking mechanism to ensure that the connection between the gold finger 60 and the circuit board 50 is secure and not easily loosened. At the same time, the insertion design of the gold finger 60 also facilitates installation and removal, and makes subsequent maintenance and upgrades easier.

[0053] The connection between the gold finger 60 and the circuit board 50 allows the gold finger 60 to transmit the received signals to the processor or other related components on the circuit board 50 for further processing. This efficient signal transmission ensures that the robot can display the facial expression data sent by the facial expression integrated chip 40 in real time and accurately.

[0054] The gold finger 60 ensures efficient signal transmission, reduces signal loss and latency, and improves the robot's response speed and performance. Simultaneously, the connection between the gold finger 60, the expression display screen 30, and the circuit board 50 exhibits excellent stability and reliability, resisting the effects of external factors such as vibration and impact, ensuring the robot's long-term stable operation. Furthermore, the plug-in design of the gold finger 60 facilitates installation, disassembly, and maintenance, reducing the robot's maintenance costs and complexity.

[0055] In one specific embodiment, the abutment plate 20 is connected to the top of the mobile monitoring robot and is disposed along the inside of the housing 10 away from the top of the mobile monitoring robot.

[0056] Specifically, the abutment plate 20 is connected to the top of the mobile monitoring robot and is disposed within the housing 10 in a direction away from the top of the robot. This means that the abutment plate 20 is located inside the housing 10, with its top edge connected to the outer top of the robot, while the rest extends downward into a deeper part of the housing 10.

[0057] The abutment plate 20 may be connected to the top of the robot and the housing 10 by screws, clips, or other fastening methods. This installation method ensures the stability and reliability of the abutment plate 20 and prevents loosening or detachment due to vibration or impact.

[0058] The abutment plate 20, as a structural component within the housing 10, provides necessary support and protection for the circuit board 50. It prevents damage or deformation of the circuit board 50 due to vibration, impact, or other external factors, ensuring the normal operation of the circuit board 50.

[0059] The abutment plate 20 divides the interior of the housing 10 into different areas, such as the expression display area 11 and the circuit board mounting area 12. This separation helps optimize space utilization, allowing for the orderly installation and wiring of various components, thus improving the overall performance and reliability of the robot.

[0060] The abutment plate 20 may also be combined with a heat dissipation system to help dissipate heat from the circuit board 50 through heat conduction or heat convection. When the circuit board 50 is working, the heat generated is transferred to the housing 10 through the abutment plate 20 and then dissipated through natural convection or forced cooling, thereby maintaining the normal operating temperature of the circuit board 50.

[0061] The design of the abutment plate 20 makes the robot's internal structure more compact and orderly, improving space utilization. Through a robust connection method and a reasonable layout, the abutment plate 20 enhances the robot's overall stability and reliability. The design of the abutment plate 20 also facilitates subsequent maintenance and upgrades, reducing maintenance costs and difficulty.

[0062] In one specific embodiment, the circuit board 50 is located at the end of the abutment plate 20 away from the top of the mobile robot. The abutment plate 20 abuts against the circuit board 50 along the top of the mobile monitoring robot. The abutment angle between the abutment plate 20 and the circuit board 50 is denoted as A1, and satisfies the following relationship:

[0063] A1 < 90°.

[0064] Specifically, the circuit board 50 is located at the end of the abutment plate 20 opposite to the top of the mobile robot. This means that the circuit board 50 is installed below or behind the abutment plate 20, maintaining a certain distance from the top of the robot.

[0065] The abutment plate 20 extends along the top of the mobile monitoring robot and abuts against the circuit board 50. This design ensures the secure installation of the circuit board 50 within the housing 10 while optimizing space utilization.

[0066] The contact angle between the abutment plate 20 and the circuit board 50 is denoted as A1. This angle is the included angle between the contact surfaces of the abutment plate 20 and the circuit board 50, and is used to describe their relative positional relationship.

[0067] A1 < 90°. This means that the angle between the abutment plate 20 and the circuit board 50 is an acute angle, i.e., the abutment plate 20 is tilted relative to the circuit board 50 towards the top of the robot. And the tilt angle is relative to the transparent portion 13 of the housing 10.

[0068] By adjusting the abutment angle A1, the space within the housing 10 can be utilized more effectively. When A1 is less than 90°, the space between the abutment plate 20 and the circuit board 50 is utilized more efficiently, helping to reduce the overall size of the robot. A smaller abutment angle A1 helps to enhance the stability of the circuit board 50 within the housing 10. Because the abutment plate 20 is tilted towards the top of the robot, it provides better support and fixation, preventing the circuit board 50 from loosening or falling off due to vibration or impact.

[0069] In one specific embodiment, the housing 10 includes a transparent portion 13, and the display surface of the expression display screen 30 is placed on the side of the transparent portion 13 that is away from the circuit board mounting area 12. The transparent portion 13 is used to provide feedback of the expression of the expression display area 11 to the user.

[0070] Specifically, a portion of the housing 10 is designed to be made of a transparent or translucent material; this portion is referred to as the transparent section 13. It allows light to pass through, enabling the user to clearly see the expression display screen 30 inside the housing 10.

[0071] The transparent portion 13 is located on the side of the expression display screen 30 that faces away from the circuit board mounting area 12. This means that the display surface of the expression display screen 30 is placed inside the transparent portion 13, which serves as the interface between the user and the display screen.

[0072] The main function of the transparent part 13 is to provide feedback on the expressions displayed in the expression display area 11 to the user. When the expression display screen 30 displays a specific expression, these expressions are clearly presented to the user through the transparent part 13, enhancing the robot's interactivity and user experience.

[0073] The transparent section 13 allows the content displayed on the expression display screen 30 to be presented directly and clearly to the user without the need for an additional display window or interface, thus improving the efficiency of information transmission. Since the transparent section 13 directly serves as the interface between the expression display screen 30 and the user, eliminating the need for additional display devices or components, this helps reduce the overall size and weight of the robot. The surface of the transparent section 13 is typically smooth, making it less prone to accumulating dust or stains, and therefore relatively easy to clean and maintain.

[0074] In one specific embodiment, the abutment plate 20 is located at the end of the expression display screen 30 opposite to the transparent shell.

[0075] Specifically, the mounting plate is located at the end of the expression display screen 30 that faces away from the transparent shell. This means that the mounting plate 20 is not directly exposed to the user's view, but is hidden behind the expression display screen 30 and connected to the expression display screen 30 through the internal structure of the shell 10.

[0076] The main function of the abutment plate 20 is to support and fix the expression display screen 30. It ensures the stable installation of the expression display screen 30 within the housing 10 and prevents loosening or detachment due to vibration, impact or other external factors.

[0077] In one specific embodiment, the mobile monitoring robot is equipped with an expression display screen 30. After the expression display screen 30 is connected to the expression integrated chip 40, the expression display screen 30 can display any expression.

[0078] Specifically, the mobile monitoring robot is equipped with one or more facial expression displays 30, each of which is connected to an facial expression integrated chip 40. This connection may be achieved through a physical interface (such as a slot or connector) or wirelessly (such as Bluetooth or Wi-Fi).

[0079] When the expression integration chip 40 receives an expression command from the robot control system or an external input, it generates corresponding expression data according to the command. This data is then sent to the expression display screen 30 connected to the expression integration chip 40, thereby displaying the expression.

[0080] The expression integration chip 40 may store multiple expression data, which can be static images, dynamic images, or video clips. When a command to switch expressions is received, the expression integration chip 40 selects a new expression from the stored expression data and sends it to the expression display screen 30 for display.

[0081] After receiving facial expression data from the facial expression integrated chip 40, the facial expression display screen 30 immediately decodes and renders the data, presenting the facial expression clearly to the user in the form of an image or video. This display may be continuous (such as animated facial expressions) or static (such as still images).

[0082] In one specific embodiment, the mobile monitoring robot is provided with two expression display screens 30, which are respectively connected to the expression integrated chip 40. The two expression display screens 30 are located on the same horizontal line and are arranged opposite to each other to form the eyes of the mobile monitoring robot.

[0083] One of the expression display screens 30 is used to display the left eye of the mobile monitoring robot, and the other expression display screen 30 is used to display the right eye of the mobile monitoring robot.

[0084] Specifically, the mobile monitoring robot is equipped with two facial expression displays 30, which are connected to the facial expression integrated chip 40. These two displays are located on the same horizontal line and are set opposite to each other, thus forming the robot's "eyes".

[0085] One of the expression displays 30 is used to show the robot's left eye, and the other is used to show the right eye. This design allows the robot to simulate human eye expressions, enhancing the realism and interactivity of the expressions.

[0086] In one specific embodiment, the mobile monitoring robot is provided with three expression display screens 30, which are respectively connected to the expression integrated chip 40. Each expression display screen 30 is used to display the left eye, right eye and mouth of the mobile monitoring robot respectively.

[0087] Specifically, the mobile monitoring robot is equipped with three facial expression displays 30, which are connected to the facial expression integrated chip 40. These three displays correspond to the robot's left eye, right eye, and mouth, respectively, thus forming a complete facial expression system.

[0088] The left and right eye displays are used to simulate the robot's eye expressions, while the mouth display simulates changes in mouth expressions. This design allows the robot to more comprehensively simulate human facial expressions, enhancing the richness and realism of its expressions.

[0089] All three facial expression displays 30 are connected to the same facial expression integrated chip 40, enabling them to display facial expressions synchronously. This means that when the robot needs to express a certain emotion or reaction, its eyes and mouth will simultaneously display the corresponding expression, thus ensuring the coherence and consistency of the facial expressions.

[0090] In addition to synchronized display, the three expression displays 30 can also achieve more refined coordinated movements through complex programming. For example, when the robot expresses a smile, its eyes will curve into crescent shapes, and its mouth will curve upwards, forming a vivid smiling expression. This coordinated movement makes the robot's expressions more natural and realistic.

[0091] Therefore, the aforementioned mobile monitoring robot 100 capable of switching facial expressions integrates an expression chip 40 and an expression display screen 30, enabling the mobile monitoring robot to flexibly switch and display multiple expressions, thus enhancing the robot's interactivity and user-friendliness. Simultaneously, since mobile robots are easily subject to collisions during patrols, a stop plate 20 is provided to fix the position of the expression display screen 30, improving the stability of the mobile monitoring robot.

[0092] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
