Description

Technical Field

[0001] This application relates to the field of robotics, and more particularly to a robot. Background Technology

[0002] With the continuous development of robotics technology, robots are no longer limited to indoor applications such as shopping malls and engineering projects, but may also be used in outdoor environments. Due to the unpredictable nature of outdoor weather, robots are frequently exposed to rain, snow, and other extreme conditions, thus requiring high levels of sealing and waterproofing. Robots integrate control boards, which generate considerable heat during operation. If the control boards are not cooled in a timely manner, the circuit boards may fail due to excessive heat.

[0003] To ensure stable robot operation, a heat dissipation mechanism is installed on the robot to cool the control board. This mechanism includes a fan and heat dissipation channels. The fan blows air onto the circuit board, which then flows into the external environment through the heat dissipation channels. In related technologies, the openings of the heat dissipation channels face the sides of the robot, allowing external moisture to easily enter the channels and then the robot's interior, potentially damaging the internal circuit boards and failing to meet the robot's waterproofing requirements. Furthermore, the air duct mechanism on the robot occupies a significant amount of space, leaving insufficient space for other functional components, resulting in low space utilization on the robot. Utility Model Content

[0004] This application provides a robot designed to improve the technical problem of low waterproof rating of heat dissipation channels in existing robots.

[0005] This utility model provides a robot, including a shell and a heat dissipation module; The heat dissipation module includes: A fan, disposed within the internal space of the housing, includes an air inlet and an air outlet. The air inlet is used to draw air from the internal space. When the robot is in an upright position, the air inlet is oriented horizontally or tilted downwards relative to the horizontal direction. The air duct includes an inlet and an outlet. The air duct is disposed in the internal space. The inlet of the air duct is connected to the air outlet of the fan. The outlet of the air duct is configured to connect to the external environment, and the outlet of the air duct faces the bottom of the robot. The air duct includes a heat-conducting component on part or all of its sidewall. The heat-conducting component is used to conduct heat from the heating component. The heating component is disposed in the internal space. The air blown out by the fan outlet can conduct the heat from the heat-conducting component to the external environment through the air duct inlet and outlet. The air duct includes a first part and a second part arranged along the airflow direction within the air duct. The first part includes the heat-conducting component, and the second part includes an air duct shell. The first part and the second part are connected. The second part includes an upper air duct and a first lower air duct and a second lower air duct, both connected to the upper air duct. The first lower air duct and the second lower air duct are spaced apart, and a receiving space is provided between the first lower air duct and the second lower air duct.

[0006] Optionally, the thermal conductivity of the air duct shell is lower than that of the thermal conductivity of the thermally conductive component.

[0007] Optionally, the first part of the air duct further includes a covering, and the heat-conducting component forms part of the sidewall of the first part of the air duct in the circumferential direction. The covering cooperates with the heat-conducting component to enclose and form the first part of the air duct.

[0008] Optionally, the robot also includes a camera, which is mounted in the housing space.

[0009] Optionally, the second part of the air duct is part of the robot's outer shell.

[0010] Optionally, when the robot is in an upright position, the air duct is arranged vertically downwards, and the inlet of the air duct is higher than the outlet of the air duct.

[0011] Optionally, the heating element includes a control board, and the heat-conducting element is mounted on the control board.

[0012] Optionally, there are at least two heat dissipation modules, which are spaced apart in the internal space.

[0013] Optionally, the number of heat dissipation modules is two, and when the robot is in an upright state, the two heat dissipation modules are respectively located on the front and rear sides of the internal space.

[0014] Optionally, the robot further includes a motor capable of controlling at least a portion of the robot to move, the motor being disposed between the two heat dissipation modules.

[0015] In this invention, the fan's inlet draws in gas, and the fan's outlet blows gas out towards the duct inlet. The gas carries away the heat from the heat-conducting components in the duct and is then blown into the external environment through the duct outlet. The heat-conducting components are used to conduct heat from the heat-generating components, thereby improving the heat dissipation efficiency of the heat-generating components. Furthermore, a closed-loop forced convection circulation is established inside the robot, significantly reducing the internal temperature of the joints and allowing the robot to work continuously under higher loads.

[0016] Furthermore, when the robot is in an upright position, the fan's air inlet is positioned horizontally or tilted downwards relative to the horizontal direction. Since moisture typically flows vertically downwards under gravity, it is less likely for moisture to enter the fan's air inlet, and consequently, the fan is less likely to blow moisture into the heat-conducting components and air ducts. The air duct's outlet is configured to connect to the external environment, and the outlet faces downwards towards the robot's bottom, further reducing the likelihood of moisture entering the air duct and improving the robot's waterproof capabilities.

[0017] In addition, the first lower air duct and the second lower air duct are spaced apart, and there is a space between the first lower air duct and the second lower air duct. The space can be used to install components such as cameras, sensors, and radar, which improves the robot's compactness and space utilization. Attached Figure Description

[0020] To make the technical problems, technical solutions, and beneficial effects solved by this application clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0021] like Figure 1 and Figure 2 As shown, this application provides a robot, including a shell 1 and a heat dissipation module 2; The heat dissipation module 2 includes: A fan 21 is disposed within the internal space of the housing 1. The fan 21 includes an air inlet and an air outlet. The air inlet of the fan 21 is used to draw air from the internal space. When the robot is in an upright position, the air inlet of the fan 21 is oriented horizontally or inclined downwards relative to the horizontal direction. The air duct includes an inlet and an outlet. The air duct is disposed in the internal space. The inlet of the air duct is connected to the air outlet of the fan 21. The outlet of the air duct is configured to connect to the external environment, and the outlet of the air duct faces the bottom of the robot. The air duct includes a heat-conducting component on part or all of its sidewall. The heat-conducting component can conduct heat from the heating component 3. The heating component 3 is disposed in the internal space. The air blown out by the air outlet of the fan 21 can conduct the heat from the heat-conducting component to the external environment through the air duct inlet and the air duct outlet. The air duct includes a first part 22 and a second part 23 arranged along the airflow direction within the air duct. The first part 22 includes the heat-conducting component. The second part 23 includes an air duct shell. The first part 22 and the second part 23 are connected. The second part 23 includes an upper air duct 231 and a first lower air duct 232 and a second lower air duct 233, both connected to the upper air duct 231. The first lower air duct 232 and the second lower air duct 233 are spaced apart, and a receiving space is provided between the first lower air duct 232 and the second lower air duct 233.

[0022] The fan 21 is a centrifugal fan. In one embodiment, the outer casing 1 is provided with a filter plate opposite to the air inlet of the fan 21. External air enters the air inlet of the fan 21 after being filtered by the filter plate. It can be understood that external air can also enter the air inlet of the fan 21 directly without passing through the filter plate. When the robot is in an upright position, the air inlet of the fan 21 is horizontal or oriented diagonally downwards, making it difficult for moisture to enter the air inlet of the fan 21. It can be understood that when the robot is in working condition, the robot's hardware generates heat during operation, and the temperature of the robot's internal space will rise. When the ambient temperature of the robot is low, water vapor in the robot's internal space will condense when it encounters the cooler outer casing. Since the air inlet of the fan 21 is oriented horizontally or diagonally downwards, it is difficult for the condensate to enter the heat dissipation module through the air inlet of the fan 21.

[0023] The outlet of the fan 21 faces the inlet of the air duct, and the outlet of the air duct is connected to the external environment; the outlet of the air duct can be vertical or inclined downwards. The heat-conducting components include, but are not limited to, radiators, heat-conducting cylinders, etc., and the heat-generating components 3 include, but are not limited to, control boards, motors, etc.; the air duct can be a through-hole structure formed by the heat-conducting components, or it can be a through-hole structure formed by the heat-conducting components and other components (such as housings).

[0024] Specifically, the air inlet of the fan 21 draws in gas, and the air outlet of the fan 21 blows gas out toward the air duct inlet. The gas carries away the heat of the heat-conducting component in the air duct and is blown into the external environment through the air duct outlet. The heat-conducting component is used to transfer heat to the heat-generating component 3, thereby improving the heat dissipation efficiency of the heat-generating component 3. Furthermore, a forced convection circulation is established inside the robot, which greatly reduces the temperature inside the joints and allows the robot to work continuously under higher loads.

[0025] In this invention, when the robot is in an upright position, the air inlet of the fan 21 is oriented horizontally or tilted downwards relative to the horizontal direction. Water typically flows vertically downwards under gravity, making it difficult for water to enter the air inlet of the fan 21. Consequently, the fan 21 is less likely to blow water into the heat-conducting components and the air duct. The outlet of the air duct is configured to connect to the external environment, and the outlet faces the bottom of the robot, thus preventing water from entering the air duct and improving the robot's waterproof rating.

[0026] Furthermore, the air outlet of the fan 21 blows air towards the first part 22 of the air duct. After absorbing heat from the heat-conducting component in the first part 22, the air enters the second part 23 of the air duct and is finally blown out to the external environment through the second part 23. The air duct includes the first part 22 and the second part 23. The air duct shell surrounds the second part 23. The heat-conducting component can be directly formed in the first part 22, or it can be inserted into the first part 22. The heat-conducting component does not need to be inserted into the second part 23 surrounded by the air duct shell, which facilitates the assembly and disassembly of the heat-conducting component.

[0027] Furthermore, the air duct shell surrounds the upper air duct 231, the first lower air duct 232, and the second lower air duct 233; the end of the first lower air duct 232 away from the upper air duct 231 and the end of the second lower air duct 233 away from the upper air duct 231 are both provided with air duct outlets; the end of the upper air duct 231 away from the first lower air duct 232 is connected to the first part 22 of the air duct. In this embodiment, the first lower air duct 232 and the second lower air duct 233 are spaced apart, and there is a receiving space between the first lower air duct 232 and the second lower air duct 233. The receiving space can be used to install components such as the camera 4, sensors, and radar, which improves the compactness of the robot.

[0028] In one embodiment, such as Figure 1 and Figure 2 As shown, the thermal conductivity of the air duct shell is lower than that of the thermal conductivity of the thermally conductive component.

[0029] In one embodiment, such as Figure 1 and Figure 2 As shown, the first part 22 of the air duct also includes a covering (not shown in the figure). The heat-conducting component forms part of the sidewall of the first part 22 of the air duct in the circumferential direction. The covering cooperates with the heat-conducting component to enclose and form the first part 22 of the air duct.

[0030] The covering includes, but is not limited to, tape, and panels; the covering can wrap around the heat-conducting component, and the first part 22 of the air duct and the opposite ends of the covering are respectively connected to the air outlet of the fan 21 and the air duct shell.

[0031] Specifically, the gas blown out of the air outlet of the fan 21 enters the first part 22 of the air duct formed by the covering, and the gas is less likely to leak in the first part 22 of the air duct, which improves the heat dissipation efficiency of the heat-conducting component in the first part 22 of the air duct, thereby improving the heat dissipation efficiency of the heat-generating component 3.

[0032] In one embodiment, such as Figure 1 As shown, the robot also includes a camera 4, which is installed in the housing space.

[0033] In this embodiment, the camera 4 can be installed in the accommodating space between the first lower air duct 232 and the second lower air duct 233, which facilitates the installation and removal of the camera 4.

[0034] In one embodiment, such as Figure 1 and Figure 2 As shown, the second part 23 of the air duct is part of the outer shell 1 of the robot.

[0035] The air duct shell and the outer shell 1 are integrally formed, and the second part of the air duct 23 is integrated on the outer shell 1. There is no need to set up a separate shell for the second part of the air duct 23, which reduces the manufacturing cost of the robot.

[0036] In one embodiment, such as Figure 1 and Figure 2 As shown, when the robot is in an upright position, the air duct is set vertically downwards, and the inlet of the air duct is higher than the outlet of the air duct.

[0037] In this embodiment, the air duct is vertically downward, making it difficult for moisture to enter the air duct. That is, moisture is not easily able to enter the internal space through the air duct, thus improving the robot's waterproof effect.

[0038] In one embodiment, the heating component 3 includes a control board, and the heat-conducting component is mounted on the control board.

[0039] During operation, the control board generates a large amount of heat. The heat-conducting component absorbs the heat from the control board through heat conduction. Gas is blown onto the heat-conducting component in the air duct, thereby accelerating the heat dissipation efficiency of the heat-conducting component and the circuit board, and extending the service life of the control board.

[0040] In one embodiment, there are at least two heat dissipation modules 2, which are spaced apart in the internal space.

[0041] In this embodiment, at least two heat dissipation modules 2 are provided, and the at least two heat dissipation modules 2 can dissipate heat from at least two heat-generating components 3, thereby further improving the heat dissipation efficiency of the robot.

[0042] In one embodiment, there are two heat dissipation modules 2, and when the robot is in an upright state, the two heat dissipation modules 2 are respectively located on the front and rear sides of the internal space.

[0043] One of the air ducts is located at the front of the outer shell 1, and the other air duct is located at the rear of the outer shell 1. Heat dissipation modules 2 are provided at both the front and rear of the shell, further improving the robot's heat dissipation efficiency. It is understood that in some embodiments, the internal space of the robot's shell contains more than one circuit board. Different heat dissipation modules can target different circuit boards for heat dissipation. Simultaneously, a motor for the robot's waist can be placed between two heat dissipation modules to provide the robot with a compact design.

[0044] In one embodiment, the robot further includes a motor capable of controlling at least a portion of the robot to move, the motor being disposed between the two heat dissipation modules.

[0045] In this embodiment, the two heat dissipation modules can also dissipate heat from the motor, extending the service life of the motor.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0048] The terms “first,” “second,” “third,” “fourth,” etc., in this application (if present) are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0049] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0050] Unless otherwise specified, all steps in this application may be performed sequentially or randomly. For example, if the method includes steps A and B, it means that the method may include steps A and B performed sequentially, or it may include steps B and A performed sequentially. For example, if the method may also include step C, it means that step C may be added to the method in any order. For example, the method may include steps A, B, and C, or it may include steps A, C, and B, or it may include steps C, A, and B, etc.

[0051] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
