Description

Technical Field

[0001] This application relates to the technical field of equipment heat dissipation, and in particular to a body heat dissipation structure and a delivery robot. Background Technology

[0002] Delivery robots are automated devices capable of autonomous navigation and obstacle avoidance. They are primarily used for the automated handling and delivery of goods in various scenarios. They can operate in places such as restaurants, hospitals, large shopping malls, and logistics centers, significantly improving efficiency, reducing labor costs, and increasing delivery accuracy. Delivery robots have internal compartments for storing and retrieving items to be delivered.

[0003] Due to the need for protection, delivery robots typically adopt a closed structure design. However, the body usually integrates heat-generating components such as CPUs and GPUs to perform data processing and logic control, which generates a lot of heat. Especially when working continuously for a long time or in high-temperature environments, the heat generated and accumulated inside the body will be even greater. Conventional heat dissipation methods are not effective enough, causing the delivery robot to operate in an overheated state for a long time, which can easily lead to malfunctions and damage, affecting its service life and reliability. Utility Model Content

[0004] Therefore, it is necessary to provide a body heat dissipation structure and a delivery robot to address the problem of poor heat dissipation, which affects service life and reliability.

[0005] A first aspect of this application proposes a fuselage heat dissipation structure, comprising:

[0006] The fuselage body includes a compartment and an outer shell that are assembled together. The outer shell is located outside the compartment and cooperates with the compartment to form an air inlet duct, a receiving cavity, and an air outlet duct. The air inlet duct, the receiving cavity, and the air outlet duct are sequentially connected to form a heat dissipation channel. The fuselage body also has an air inlet and an air outlet. The air inlet is connected to the air inlet duct, and the air outlet is connected to the air outlet duct. A heating element is installed inside the receiving cavity.

[0007] A wind-driven assembly is installed within the heat dissipation channel to drive airflow within the heat dissipation channel.

[0008] The heat dissipation structure of this solution is applied to delivery robots. When the robot is working, the heat-generating components installed inside the main body generate a large amount of heat. The wind-driven component is activated to create a suction force in the heat dissipation channel, thereby drawing cool air from the external environment into the air intake duct. The cool air then flows into the receiving cavity, where it exchanges heat with the heat-generating components, absorbing their heat to form hot air. This hot air further flows into the air outlet duct and is finally discharged to the external environment through the air outlet. This cycle ensures a continuous flow of cool air into the heat dissipation channel to participate in cooling the heat-generating components, effectively dissipating heat to the outside of the robot, improving heat dissipation efficiency, preventing the delivery robot from operating in an overheated state for extended periods, preventing malfunctions and damage, and ensuring service life and reliability.

[0032] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0033] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, 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, and therefore should not be construed as a limitation of this application.

[0034] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0035] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0036] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0037] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0038] See Figure 1 , Figure 1 The present application illustrates a delivery robot 100, which includes a chassis 20, a body 10, a column 30, a first robotic arm 40, a second robotic arm 50, and an interactive screen 60. The body 10 is mounted on the chassis 20, the column 30 is mounted on the body 10, the first robotic arm 40 and the second robotic arm 50 are respectively mounted on the left and right sides of the column 30, and the interactive screen 60 is mounted on the top of the column 30.

[0039] During operation, the chassis 20 provides the necessary mobility for the delivery robot 100 to remotely and autonomously deliver items.

[0040] The chassis 20 can be any of the following: wheeled chassis, tracked chassis, or footed chassis, and the specific type can be flexibly selected according to actual needs. The chassis 20 is equipped with visual sensors, navigation components, and other functional components to achieve autonomous navigation, obstacle avoidance, and other safe operation.

[0041] The body 10 is the main structure of the delivery robot 100, serving to house the integrated column 30, the first robotic arm 40, the second robotic arm 50, and the interactive screen 60.

[0042] The first robotic arm 40 and the second robotic arm 50 are multi-axis robotic arms, such as any one of three-axis robotic arms or five-axis robotic arms, which have a high degree of freedom of movement and can perform operations such as flexibly grasping and transferring objects, as well as performing operations such as pressing ladders, to meet the needs of various usage scenarios.

[0043] The interactive screen 60 can be used by the delivery robot 100 to interact with users, enabling the delivery robot 100 to perform user requests. For example, the interactive screen 60 can be, but is not limited to, a touch screen.

[0044] Since the delivery robot 100 of this application is equipped with a first robotic arm 40 and a second robotic arm 50, it requires high computing power to perform visual recognition and arm control calculations. Therefore, it is necessary to continuously dissipate heat from the computing units arranged on the body 10. Based on this, this application proposes a body heat dissipation structure.

[0045] Please continue reading. Figures 1 to 3 The diagram shows a fuselage heat dissipation structure 10a according to one embodiment, which includes a fuselage body 11, a first air guide 13, a second air guide 14, and a wind drive assembly 15.

[0046] The fuselage body 11 includes a compartment 111 and an outer shell that are assembled together. The outer shell is located outside the compartment 111 and cooperates with the compartment 111 to form an air inlet duct 132, a accommodating cavity 113 and an air outlet duct 142. The air inlet duct 132, the accommodating cavity 113 and the air outlet duct 142 are connected in sequence and cooperate to form a heat dissipation channel.

[0047] In addition, the main body 11 is provided with an air inlet 131 and an air outlet 141. The air inlet 131 is connected to the air inlet duct 132, and the air outlet 141 is connected to the air outlet duct 142.

[0048] The heat dissipation structure 10a also includes a first air guide 13 and a second air guide 14 connected to the main body 11. The first air guide 13 is located on the first side of the main body 11, and the second air guide 14 is located on the second side of the main body 11.

[0049] More specifically, the first air guide 13 is installed between the shell body 116 and the cabin 111 and is located on the first side of the cabin 111, and the air inlet 131 is opened in the first air guide 13; the second air guide 14 is installed between the shell body 116 and the cabin 111 and is located on the second side of the cabin 111, and the air outlet 141 is opened in the second air guide 14.

[0050] The first side and the second side can be the left and right sides or the front and back sides of the delivery robot 100.

[0051] More specifically, the outer shell includes a shell body 116 and a cover 112 disposed above the shell body 116. The chamber 111 and the cover 112 cooperate to form a receiving cavity 113. A heat dissipation unit 12 is installed inside the receiving cavity 113, and the heat dissipation unit 12 is heat-transfer connected to the heat-generating device.

[0052] For example, the cabin 111 has a square box structure, and its interior has a compartment 1111 for storing items to be delivered.

[0053] In this application, the first side and the second side specifically refer to the left and right sides of the hull 111 (see reference). Figure 2 (From a product perspective). The first air guide 13 and the second air guide 14 can be integrally formed with the cabin 111 or they can be detached and assembled, depending on actual needs.

[0054] Specifically, the first air guide 13 and the second air guide 14 are made of square tube, round tube or other materials such as metal or plastic. They are simple in structure, easy to obtain, low in cost and light in weight. At the same time, the air inlet duct 132 and the air outlet duct 142 are easy to form.

[0055] The air drive assembly 15 is installed in the heat dissipation channel to drive the air to flow in the heat dissipation channel.

[0056] The accommodating cavity 113 is located above the air inlet duct 132 and the air outlet duct 142, and is arranged between the air inlet duct 132 and the air outlet duct 142, so that the heat dissipation channel forms an inverted U-shaped flow channel.

[0057] by Figure 2 From this perspective, the airflow path is as follows: it enters the first air guide 13 from the left and flows upward, then turns to the right and enters the receiving cavity 113, and finally turns downward and flows into the second air guide 14, and is finally discharged from the second air guide 14. The flow path is simple and smooth, which can improve airflow efficiency and thus help improve heat dissipation.

[0058] In summary, implementing the technical solution of this embodiment will achieve the following beneficial effects: The body heat dissipation structure 10a of this solution is applied to the delivery robot 100. When the delivery robot 100 is working, and the heating device installed in the body 11 generates a large amount of heat, the wind drive component 15 is activated to form a suction force in the heat dissipation channel, thereby drawing cold air from the external environment from the air inlet 131 into the air inlet duct 132, and flowing into the receiving cavity 113 along the air inlet duct 132. The heat dissipation unit 12 cooperates with the heat transfer of the heating device to absorb the heat generated by the heating device. The generated heat is simultaneously exchanged with the heat dissipation unit 12 by the cold air, thereby absorbing the heat from the heat dissipation unit 12 to form hot air. The hot air further flows into the air outlet duct 142 and is finally discharged to the external environment from the air outlet 141. This cycle ensures that a continuous flow of cold air into the heat dissipation channel participates in the heat dissipation and cooling of the heat-generating components, thereby dissipating heat to the outside of the machine in a timely manner, improving the heat dissipation effect, preventing the delivery robot 100 from operating in an overheated state for a long time, preventing malfunctions and damage, and ensuring service life and reliability.

[0059] It should also be noted that the heat generated by the heating device is absorbed by the heat dissipation unit 12, and the heat exists in the accommodating cavity 113, which can form a certain heat preservation effect on the cabin 111 from the top, thereby enhancing the reliability of the delivery robot 100 in low-temperature environments.

[0060] Please continue reading. Figures 2 to 4More specifically, based on the above embodiments, the first air guide 13 is provided with a first mounting part 133, which extends to the bottom surface of the cabin 111. The first mounting part 133 is used to assemble with the chassis 20, and the air inlet 131 is provided on the first mounting part 133.

[0061] Similarly, the second air guide 14 is provided with a second mounting part 143, which extends to the bottom of the cabin 111. The second mounting part 143 is used to assemble with the chassis 20, and the air outlet 141 is provided on the second mounting part 143.

[0062] The first mounting part 133 and the second mounting part 143 extending below the bottom surface of the cabin 111 facilitate connection and fixation with the chassis 20, so as to realize the overall assembly of the fuselage 10 onto the chassis 20. The installation method is simple and the symmetrical connection structure makes the fuselage 10 have good stress stability.

[0063] For example, the installation method of the first mounting part 133 and the second mounting part 143 with the chassis 20 can be any one or at least a combination of two of them, such as screw connection, snap connection, magnetic connection, welding, riveting, or bonding, and can be flexibly selected according to actual needs.

[0064] The air inlet 131 and the air outlet 141 are respectively located on the first mounting part 133 and the second mounting part 143, and are not blocked by the cabin 111, which can ensure smooth airflow and heat dissipation channels.

[0065] Furthermore, the first mounting part 133 has a first mating surface facing the second air guide 14, the first mating surface is used to engage with the chassis 20 at intervals to form a first gap, and the air inlet 131 is used to be hidden in the first gap.

[0066] The second mounting part 143 has a second mating surface facing the first air guide 13. The second mating surface is used to engage with the chassis 20 at intervals to form a second gap. The air outlet 141 is used to be hidden in the second gap.

[0067] On the one hand, the air inlet 131 and the air outlet 141 are respectively hidden in the first gap and the second gap, which can achieve the effect of hidden installation. Users cannot directly observe them from the appearance, thus improving the aesthetics and simplicity of the whole machine. On the other hand, since the gaps of the first gap and the second gap are small, they can effectively block debris such as stones and rainwater from the external environment, preventing them from being sucked into the heat dissipation channel and causing pollution or damage to the heat dissipation unit 12 and the wind drive assembly 15.

[0068] For example, the air inlet 131 and the air outlet 141 can be circular, square, elliptical or other shapes of slotted structures.

[0069] Please continue reading. Figure 4 In other optional embodiments, the air inlet 131 and the air outlet 141 adopt a mesh structure. In this case, the air inlet 131 and the air outlet 141 do not need to be set in the gap. The mesh size of the mesh structure is small, which can achieve a good effect of blocking debris on its own, while not affecting air circulation.

[0070] Of course, depending on actual needs, the air inlet 131 and air outlet 141 of the mesh structure can also be set in the corresponding gaps. In this way, the gaps and the mesh structure can form two barriers to achieve a better protective effect.

[0071] Please continue reading. Figure 2 and Figure 3 Furthermore, based on any of the above embodiments, the wind drive assembly 15 includes a first fan 151, which is installed inside the air inlet duct 132. During heat dissipation operation, the first fan 151 starts to generate a suction effect, thereby continuously drawing cold air from the external environment into the air inlet duct 132 from the air inlet 131, while simultaneously enabling the cold air to overcome the frictional resistance of the sidewalls of the air inlet duct 132, ensuring smooth airflow.

[0072] Furthermore, the fuselage body 11 also includes a first air guide shroud 114, which is connected to the corner of the shell body 116 and the cover 112.

[0073] The wind drive assembly 15 also includes a second fan 152, which is disposed in the accommodating cavity 113 and arranged in conjunction with the first air guide shroud 114.

[0074] During heat dissipation, the second fan 152 is activated to further draw in the cold air in the air intake duct 132, allowing the cold air in the air intake duct 132 to be directed and flow into the accommodating cavity 113 under the guidance of the first air guide shroud 114. The cold air then comes into contact with the heat dissipation unit 12, which has already absorbed heat from the heat-generating device, and absorbs the heat from the heat dissipation unit 12 through heat transfer, thereby achieving the effect of heat dissipation for the heat-generating device and the heat dissipation unit 12.

[0075] Specifically, the heat-generating device installed in the accommodating cavity 113 in this application includes at least a lower-level CPU and a higher-level CPU & GPU. The CPU (Central Processing Unit) and GPU (Graphics Processing Unit) are two crucial components of a computer system.

[0076] The CPU is the core processor of a computer system, responsible for executing instructions in computer programs and controlling and coordinating the various components of the computer system. It is primarily used for a wide range of computing tasks, such as running operating systems, browsing web pages, and running office software.

[0077] GPUs are dedicated processors designed for highly parallel computing tasks, emphasizing a large number of processing units and the ability to execute multiple simple tasks simultaneously.

[0078] Therefore, the CPU of the lower-level machine and the CPU & GPU of the upper-level machine will generate a lot of heat when the delivery robot 100 is working, and they are the objects that need to be focused on heat dissipation and cooling.

[0079] Based on this, the heat dissipation unit 12 in this application includes a first heat sink 121 and a second heat sink 122, and the wind drive assembly 15 also includes a third fan 153. The first heat sink 121 is disposed between the second fan 152 and the third fan 153, and the second heat sink 122 is disposed on the side of the third fan 153 away from the first heat sink 121.

[0080] During installation, the first heatsink 121 is configured to cool the lower-level CPU, meaning it cools the CPU. The second heatsink 122 is configured to cool the upper-level CPU and GPU, meaning it cools both the CPU and GPU. The first and second heatsinks operate independently, which helps ensure their cooling capacity, allowing heat to be absorbed and carried away by cool air in a timely manner.

[0081] For example, both the first radiator 121 and the second radiator 122 adopt a multi-fin structure, with a one-way channel formed between two adjacent fins to ensure smooth airflow.

[0082] Please continue reading. Figure 2 and Figure 3 In another embodiment, the main body 11 further includes a second air guide shroud 115, and the wind drive assembly 15 further includes a fourth fan 154 and a fifth fan 155. The second air guide shroud 115 is connected to the corner of the shell body 116 and the cover 112. The fourth fan 154 is disposed in the accommodating cavity 113 and is arranged in cooperation with the second air guide shroud 115. The fifth fan 155 is installed in the air outlet duct 142.

[0083] During heat dissipation, the fourth fan 154 is activated to create a suction effect on the hot air after heat exchange, allowing the hot air to overcome the resistance exerted by the first radiator 121, the second radiator 122, etc., and flow more effectively through the receiving cavity 113. Then, under the guidance of the second air guide shroud 115, it turns downward and flows into the air outlet duct 142. Immediately afterwards, the fifth fan 155 applies a blowing action to the hot air, so that the hot air can overcome the resistance of the side wall of the air outlet duct 142 and be discharged from the air outlet 141 more quickly.

[0084] In actual use, the items to be delivered stored in compartment 1111 may be liquid or contain liquid. During delivery, the delivery robot 100 may vibrate or shake due to uneven ground or other reasons, or due to temperature differences, which may cause spilled liquid or condensation in compartment 1111, which may easily produce odors; or the items to be delivered may have their own odor.

[0085] To address the aforementioned issues, in one optional embodiment, the cabin 111 has opposing first and second sidewalls. The first sidewall has a first through hole that connects the interior chamber 1111 of the cabin 111 to the air inlet duct 132. The second sidewall has a second through hole that connects the interior chamber 1111 of the cabin 111 to the air outlet duct 142. And / or, the first through hole is equipped with a sixth fan 16. And / or, the second through hole is equipped with a seventh fan 17.

[0086] When the sixth fan 16 and / or the seventh fan 17 are activated, air convection is created in the compartment 1111. This allows some of the air flowing into the air inlet duct 132 to enter the compartment 1111, carrying moisture and odors into the air outlet duct 142, and then expelling them to the external environment through the air outlet 141. This eliminates odors and ensures cleanliness and hygiene in the compartment 1111. Furthermore, the moisture discharged from the second through hole can be heated by the hot air discharged from the accommodating cavity 113, thus preventing the duct from becoming moldy due to dampness.

[0087] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0088] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
