[0018] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0019] Reference Figs. 1 to 3 This utility model proposes a physical heat dissipation structure for a sweeping robot, including a shell 1, which is made of metal. The shell 1 has a front side 11 and a back side 12. The back side 12 is connected to a control motherboard 2, and a heat-conducting component 3 is partially filled between the control motherboard 2 and the back side 12.

[0020] It is understandable that the shell 1 is part of the external shell of the robot vacuum cleaner, which is made of metal material, which helps to improve the heat dissipation performance. Metal (such as aluminum or stainless steel) is a material with good heat conduction performance, which can effectively conduct the heat generated inside out, avoiding overheating of electronic components. The shell 1 has a front face 11 and a back face 12, the front face 11 is the exposed side, and the back face 12 is the inside, the control board 2 is located on the back face 12 of the robot vacuum cleaner and is fixed on the back face 12 by physical connection. The control board 2 is one of the core components of the robot vacuum cleaner, responsible for processing and controlling various tasks inside the robot (such as path planning, motion control, etc.).

[0021] Between the control board 2 and the back face 12 of the shell 1, a heat-conducting material is filled. The heat-conducting part 3 is usually a material with good heat conduction performance, such as heat-conducting silica gel, heat-conducting pad, heat-conducting copper, etc. Its role is to conduct the heat generated by the control board 2 to the back face 12 of the shell 1, thereby helping to dissipate heat to the outside. This can effectively prevent the main board from overheating and improve the stability and service life of the robot.

[0022] The metal shell 1 of the embodiment helps to conduct heat out, and the control board 2 is installed on the back face 12 and is strengthened by filling the heat-conducting part 3 to enhance the heat dissipation effect. Such design can effectively improve the heat dissipation performance of the robot vacuum cleaner, ensure that the internal electronic components will not be damaged due to overheating during operation, and does not require additional heat sinks and fans, effectively reducing the size of the robot, and helping to design light and thin.

[0023] Reference Figs. 1 to 2 In an embodiment of the present application, the shell 1 is divided into an upper cover part 13 and a lower cover part 1413 connected to each other, and the edge of the lower cover part 1413 is provided with a bending part 4, and a plurality of heat dissipation holes 41 are formed in the bending part 4.

[0024] It is understandable that the shell 1 is designed to be composed of two parts, the upper cover part 13 and the lower cover part 1413, which are connected together in a certain way, which may be fixed by screws, buckles or other structural forms, which are not limited here. The upper cover and the lower cover have different functions, the upper cover may contain some visual sensors, control panels or other functional areas, and the lower cover may carry the battery, power system and other components inside the robot. The bending part 4 is a special design of the edge of the lower cover part 1413, which can enhance the stability of the shell 1 installation, increase the bearing capacity, and make the lower cover part 1413 better fit with other components during installation. The existence of the bending part 4 can also increase the overall pressure resistance and protection of the shell 1, especially when the robot vacuum cleaner needs to contact the ground, encounter impact or vibration.

[0025] The bending part 4 is provided with heat dissipation holes 41, which are designed to improve heat dissipation efficiency. The heat dissipation holes 41 help to enhance air circulation, allowing hot air to flow out from the inside of the robot, thereby accelerating heat dissipation. Through these heat dissipation holes 41, the heat generated inside the robot can be quickly discharged, avoiding the influence of accumulated heat on the normal operation of the machine. The split design of the shell 1 (upper cover and lower cover) can help the internal electronic components and heat dissipation structure to be more reasonably distributed, ensuring that the heat is more effectively conducted to the outside. The design of the bending part 4 and the heat dissipation holes 41 provides additional heat dissipation function through structural optimization, which helps to improve air circulation and heat dissipation effect.

[0026] Referring to Fig. 3 In an embodiment of the present application, the control mainboard 2 is integrated with CPU and GPU, and the position of the heat conduction piece 3 corresponds to the position of the CPU and GPU.

[0027] It can be understood that the control mainboard 2 is the core component of the robot control system, responsible for executing instructions, calculations and controlling the overall operation of the robot, which processes information from sensors, controls how the robot moves and completes tasks. The GPU is used to process visual information such as map generation, obstacle detection, path planning, etc. and other tasks that require strong computing power.

[0028] Since these two components are part of the computing core of the robot, they will generate a lot of heat during work, and effective heat dissipation measures are needed. The position of the heat conduction piece 3 is designed to align with the position of the CPU and GPU, specifically, the heat conduction piece 3 is precisely placed below or around the CPU and GPU.

[0029] Since CPU and GPU are the main heat sources, it is very important to directly dissipate heat from them. By aligning the heat conduction piece 3 with the heat source position of these key components, it can be ensured that the heat conduction piece 3 can effectively absorb the heat from the CPU and GPU and conduct it to the shell 1 of the back 12 or the heat dissipation holes 41, quickly discharging the heat.

[0030] Referring to Fig. 1 In an embodiment of the present application, the front surface 11 of the upper cover part 13 is provided with a display screen 5, and the display screen 5 is electrically connected to the control mainboard 2.

[0031] It can be understood that the upper cover part 13 of the sweeping robot is equipped with a display screen 5. This display screen 5 can be used to show the user the status, working mode, remaining power, working progress and other information of the sweeping robot. For example, the sweeping robot can display the current cleaning mode (such as automatic cleaning, edge cleaning, etc.), battery power, whether it encounters obstacles and other data. The display screen 5 is one of the interfaces for the user to interact with the robot. In addition, the display screen 5 can also display internal temperature information as needed, so that the user can check the heat dissipation condition of the robot.

[0032] Referring to Fig. 3 In an embodiment of the present application, the heat-conducting member 3 is a heat-conducting silica gel sheet.

[0033] It can be understood that the heat-conducting silica gel sheet has high thermal conductivity, which can effectively conduct heat from the heat source to the shell 1, which helps to reduce the temperature of the mainboard and avoid performance degradation or damage due to overheating. The heat-conducting silica gel sheet has good softness and compressibility, which can fill the small gaps or uneven surfaces between electronic components and the shell 1, ensuring uniform heat conduction and providing better contact effect. The heat-conducting silica gel sheet has good electrical insulation performance, which can avoid electrical short circuit or leakage while conducting heat, so it is particularly suitable for applications in electronic devices that require both heat conduction and electrical insulation. The silica gel material usually has good high temperature resistance and can work stably in high temperature environment. It can withstand temperatures as high as 200°C or even higher without degradation or performance degradation. The heat-conducting silica gel sheet not only conducts heat, but also provides certain shock absorption and buffering effect, reducing the damage to internal components caused by vibration or external impact during device operation.

[0034] The technical scheme of the utility model discloses by utilizing the metal shell 1 to help the heat export, control mainboard 2 is installed at the back 12, and the heat-conducting member 3 is filled to strengthen the heat dissipation effect. Such design can effectively improve the heat dissipation performance of the sweeping robot, ensure that internal electronic components are not damaged due to overheating during operation, and does not require additional heat sinks and fans, effectively reducing the size of the robot and facilitating lightweight design.
