Description

Technical Field

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

[0002] Existing robots have complex internal structures but relatively simple heat dissipation devices. Due to design considerations and structural compactness, air inlets and outlets are typically located on the same side of the casing, relying on cooling fans to drive airflow and achieve convective heat exchange between the inside and outside air. However, the hot air exhausted by the cooling fans tends to diffuse disorderly within the casing, reducing heat dissipation efficiency and potentially causing hot air to flow back to the air inlet area, mixing with the airflow at the inlet and severely limiting improvements in heat dissipation efficiency.

A heat dissipation assembly includes a guide pipe and a heat dissipation fan disposed within the receiving cavity. The guide pipe includes a first guide section made of a rigid material and a second guide section made of a flexible material. The first guide section and the second guide section are connected. The inlet end of the first guide section is disposed on the air outlet side of the heat dissipation fan. The second guide section is connected between the first guide section and the air outlet. The guide pipe forms a guide channel connecting the air outlet side of the cooling fan and the air outlet, and the guide channel turns at least once as it extends from the air outlet side of the cooling fan to the air outlet.

[0010] In a robot according to one embodiment of this application, the robot further includes a heating component disposed within the receiving cavity; the heat dissipation component further includes a radiator, the radiator having a first end face and a second end face opposite to each other, the heating component being arranged on the side facing the first end face, the heat dissipation fan being fixed to the second end face, and the first guide section being fixedly connected to the radiator. The heating component includes an electronic component, which includes a circuit board and heating electronic elements disposed on the circuit board.

[0011] In a robot according to one embodiment of this application, the radiator has a fan base and a heat sink base, the heat sink bases are respectively disposed on both sides of the fan base, the heat dissipation fan is mounted on the fan base, and the first guide section is mounted on the heat sink base.

[0012] In a robot according to one embodiment of this application, the extending directions of both heat sinks are approximately perpendicular to the central axis of the outlet end of the second guide section; or, the line connecting the two heat sinks is approximately perpendicular to the central axis of the outlet end of the second guide section.

[0013] In one embodiment of the robot of this application, the robot includes a heat-conducting component, and the heat-generating electronic component is connected to the heat sink through the heat-conducting component.

Even if there are other components or structural interferences within the casing, the second guide section can be appropriately bent and adjusted according to actual installation needs, reducing the requirements for installation precision within the casing and simplifying the assembly process. Furthermore, the flexible material also has a certain vibration damping effect, absorbing some of the vibration generated during the operation of the cooling fan and reducing the transmission of vibration to other parts of the casing, thus helping to reduce overall operating noise.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0024] 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.

[0025] like Figures 1 to 3 As shown, this application provides a robot including a housing 10 and a heat dissipation assembly 20. The housing 10 has a receiving cavity 13 and an air inlet 11 and an air outlet 12, both communicating with the receiving cavity 13. The air inlet 11 and the air outlet 12 are not arranged opposite each other along the front-rear direction of the housing 10, so that after gas enters the receiving cavity 13 from the air inlet 11, it flows along the airflow path formed within the receiving cavity 13 to the heat dissipation fan 21 and is discharged through the air outlet 12. The heat dissipation assembly 20 is disposed within the receiving cavity 13 and is at least used to discharge gas from the receiving cavity 13 to the outside of the housing 10 through the air outlet 12, and to introduce gas from outside the housing 10 into the receiving cavity 13 from the air inlet 11, enabling gas exchange between the receiving cavity 13 and the gas outside the housing 10.

[0026] It should be noted that the air inlet 11 and the air outlet 12 not being arranged opposite each other along the front and rear direction of the housing 10 means that the air inlet 11 and the air outlet 12 cannot form a straight airflow path that directly runs through the front and rear direction of the robot, including but not limited to situations where the air inlet 11 and the air outlet 12 are located on the same side of the housing 10, are staggered vertically, are staggered horizontally, or are arranged at an angle.

[0027] After adopting the above technical solution, the air inlet 11 and the air outlet 12 do not need to be arranged on the front and rear sides of the housing 10 respectively, which is conducive to flexibly setting the positions of the air inlet 11 and the air outlet 12 according to the internal structure and appearance requirements of the housing 10; the airflow flows along a non-linear path in the receiving cavity 13, which is conducive to flowing through the area to be cooled.

[0028] In one alternative implementation, such as Figures 3 to 7 As shown, the heat dissipation assembly 20 includes a guide pipe 22 and a heat dissipation fan 21 disposed in the receiving cavity 13. The guide pipe 22 is connected between the air outlet side of the heat dissipation fan 21 and the air outlet 12, so that the hot air discharged by the heat dissipation fan 21 can be forcibly constrained in a predetermined path from the air outlet side to the air outlet 12, thereby guiding the hot air along the predetermined path to the air outlet 12 and discharged from the housing 10, reducing the possibility of hot air diffusion in the receiving cavity 13 and backflow to the air inlet 11.

[0029] In an optional embodiment, the guide pipe 22 includes a first guide section 22a made of rigid material and a second guide section 22b made of soft material, with the first guide section 22a and the second guide section 22b connected. The inlet end of the first guide section 22a is located on the outlet side of the cooling fan 21, and the second guide section 22b connects the first guide section 22a and the air outlet 12. This not only ensures a stable and reliable connection between the inlet end of the guide pipe 22 and the cooling fan 21, maintaining shape stability under the airflow impact and vibration environment generated by the high-speed operation of the cooling fan 21, preventing deformation or displacement due to airflow pressure, thus guaranteeing airtightness and accuracy of the guide direction; it also allows the guide pipe 22 to adapt to the complex spatial layout and curved surface orientation inside the housing 10. Even if there are other components or structural interferences inside the housing 10, the second guide section 22b can be appropriately bent and its orientation adjusted according to actual installation needs, reducing the requirements for installation accuracy inside the housing 10 and simplifying the assembly process. In addition, soft materials also have a certain vibration damping and buffering effect, which can absorb some of the vibration generated when the cooling fan 21 is running, reduce the transmission of vibration to other parts of the casing 10, and help reduce the overall operating noise.

[0030] In one optional embodiment, the robot includes a head assembly 100 and a body assembly 200, with a neck assembly 300 connecting the head assembly 100 and the body assembly 200. The housing 10 includes, but is not limited to, the housing 10 on the head assembly 100 or the body assembly 200. Since the interior of the robot housing 10 is often compact, has complex curved surfaces, and houses numerous functional components, the heat-generating component 30 and the cooling fan 21 within the housing cavity 13 are typically fixed using mounting brackets. That is, the air outlet 12 on the housing 10 and the cooling fan 21 on the mounting bracket are components on two different parts, and their relative spatial positions inevitably have accumulated tolerances. If the guide pipe 22 is entirely made of rigid material, any slight misalignment will result in significant assembly stress at the connection point, potentially causing deformation and air leakage at the opening of the guide pipe 22, or even breakage of the housing 10's clips or stripping of the screws. This application can utilize the elastic deformation capability of the second guide section 22b made of soft material, so that it can freely stretch and flex in both length and radial angle, adapt to the positional deviation between the cooling fan 21 and the air outlet 12, reduce assembly stress, and help improve the sealing of the connection between the guide pipe 22 and the air outlet 12.

[0031] In an optional embodiment, the guide pipe 22 forms a guide channel 221 connecting the air outlet side of the cooling fan 21 and the air outlet 12. The guide channel 221 extends from the air outlet side of the cooling fan 21 to the air outlet 12 and undergoes at least one turn, so that the kinetic energy direction of the hot air discharged from the cooling fan 21 is forcibly deflected during the discharge of the guide channel 221, thereby adapting to the spatial layout of the air outlet 12 being staggered relative to the cooling fan 21, and facilitating the discharge of the hot air away from the air inlet 11.

[0032] In an optional embodiment, the air inlet 11 and the air outlet 12 are both located on the same side of the housing 10, so that the air inlet 11 and the air outlet 12 are concentrated on one side of the housing 10. This helps to reduce the space occupied by the ventilation structure on other sides of the housing 10, and facilitates the placement of sensors, interactive screens, operation buttons, interfaces or speaker openings according to the layout requirements of appearance and internal components.

[0033] In an optional embodiment, the air inlet 11 and / or air outlet 12 are located at the bottom of the housing 10, which can hide the air inlet 11 and / or air outlet 12 at the bottom of the housing 10, reducing the impact of the ventilation openings on the front, top or side appearance of the housing 10.

[0034] In an alternative embodiment, the air inlet 11 and / or the air outlet 12 are located on the rear side of the housing 10, thereby reserving space for the arrangement of sensor windows, interactive screens, cameras or infrared receiving windows on the front side of the housing 10 and reducing the impact of hot airflow on the area in front of the robot.

[0035] In one alternative implementation, the air inlet 11 and the air outlet 12 are offset or angled, so that a straight airflow path that runs directly through the robot in the front-back direction cannot be formed between the air inlet 11 and the air outlet 12.

[0036] In an optional embodiment, the housing 10 has an opening facing downwards from the robot, and an air inlet 11 and / or an air outlet 12 are disposed within the opening, such that the air inlet 11 and / or air outlet 12 are recessed relative to the outer surface of the housing 10, thereby reducing the impact of the air inlet 11 and / or air outlet 12 on the appearance of the housing 10 and providing space for airflow to enter and exit the housing 10.

[0037] In an optional embodiment, a dust cover is provided on the opening to prevent external dust or foreign objects from entering the receiving cavity 13, thereby reducing dust accumulation on the heating component 30 and the cooling fan 21.

[0038] In one optional embodiment, the housing 10 is a head housing 10 on the head assembly 100. The inner contour of the opening is adapted to the outer contour of the robot's neck, forming an annular gap between them for airflow. The robot's neck is typically a key joint for yaw and pitch, and its outer contour is often cylindrical, frustum-shaped, or truncated cone-shaped. When the inner contour of the opening at the bottom of the head housing 10 is adapted to the outer contour of the neck, the two form an annular gap after assembly, allowing airflow. This ensures that the hot air forced downwards from the head housing 10 by the cooling fan 21 must pass through this uniform annular gap to be discharged to the external environment. This annular gap maintains communication with the air outlet 12 when the head assembly 100 moves relative to the neck assembly 300, allowing hot air to be discharged.

[0039] In an optional embodiment, the robot further includes a yaw drive, a pitch drive, a motor bracket connected to the neck assembly 300, and a mounting bracket disposed within the receiving cavity 13. The mounting bracket has a movable slot, and the motor bracket is installed in the movable slot. The pitch drive is used to drive the motor bracket to rotate up and down relative to the mounting bracket, and the yaw drive is used to drive the motor bracket to rotate left and right relative to the neck assembly 300. In this application, the opening is located at the bottom of the head housing 10, and its outline is conformal to the shape of the neck assembly 300 to form an annular gap for airflow, and the annular gap remains connected when the head assembly 100 moves relative to the neck assembly 300.

[0040] It should be noted that the shell 10 can also be the body shell 10 on the body assembly 200. This application does not limit it. Its principle is the same as that of the head shell 10, and this application will not repeat it.

[0041] In one alternative implementation, such as Figure 3 , Figures 7 to 10 As shown, the robot also includes a heating component disposed within the receiving cavity. The heat dissipation component 20 further includes a radiator 23, which has a first end face 23a and a second end face 23b facing each other. The heating component 30 is arranged on the side facing the first end face 23a. The cooling fan 21 is fixed to the second end face 23b. The first guide section 22a is fixedly connected to the radiator 23, so that the heat generated by the heating component 30 can be conducted to the radiator 23 with the shortest vertical distance and diffused throughout the entire radiator 23. Then, the airflow generated by the cooling fan 21 carries away the heat on the surface of the radiator 23. At the same time, the fixed connection between the first guide section 22a and the radiator 23 ensures that the high-speed airflow thrown out from the cooling fan 21 can be completely guided into the first guide section 22a, reducing leakage and flow loss when the airflow enters the first guide section 22a from the radiator 23, thereby enabling the hot air to be quickly discharged from the air outlet 12.

[0042] In an optional embodiment, the heating component 30 includes an electronic component, which includes a circuit board 31 and a heating electronic element 311 disposed on the circuit board. The heat dissipation component 20 is disposed on the heating electronic element 311 and is used to quickly conduct the heat generated by the heating electronic element 311 during operation to the heat sink 23. Then, the heat is forced to be discharged through the air outlet 12 via the heat dissipation fan 21 through the guide pipe 22, thereby achieving effective cooling of the heating electronic element 311 and ensuring that the heating component 30 can operate stably for a long time within the allowable temperature range.

[0043] In an optional embodiment, the heat-generating electronic component 311 is connected to the heat sink 23 via a thermally conductive component to ensure that the heat from the heat-generating electronic component 311 can be quickly transferred to the heat sink 23. The thermally conductive component includes, but is not limited to, thermally conductive adhesive.

[0044] In an optional embodiment, the radiator 23 has a fan base 231 and a heat sink 232. The heat sink 232 is respectively disposed on both sides of the fan base 231. The cooling fan 21 is mounted on the fan base 231, and the first guide section 22a is mounted on the heat sink 232. When the cooling fan 21 is running, the airflow discharged by the cooling fan 21 can flow through the heat sink 232 located on both sides of the fan base 231, so as to exchange heat with the airflow using the two heat sinks 232.

[0045] It should be noted that the heat sink 232 and the fan base 231 can be integrally formed structural components, or they can be separately designed structural components that are then fixed together by assembly. This application does not impose any limitations. In an optional embodiment, the extending directions of both heat sinks 232 are approximately perpendicular to the central axis of the outlet end of the second guide section 22b; or, the line connecting the two heat sinks 232 is approximately perpendicular to the central axis of the outlet end of the second guide section 22b, thereby accommodating the arrangement of the heat sink 232 and the air outlet 12 in different directions. The fact that the central axis of the outlet end of the second guide section 22b is approximately perpendicular to the extending direction of the heat sink 232 allows the air outlet 12 to be positioned at a location different from the extending direction of the heat sink 232, for example, at the bottom of the housing 10.

[0046] It should be noted that "approximately vertical" includes 90 degrees vertical or approximately 90 degrees vertical. Approximate 90 degrees includes angles such as 89 degrees or 91 degrees, and also includes angles ranging from 85 degrees to 90 degrees or from 90 degrees to 95 degrees.

[0047] In an optional embodiment, the fan base 231 is recessed relative to the heat sink base 232 to form a recess 2311. The recess 2311 is used to accommodate the cooling fan 21 and provide space for the operation of the cooling fan 21, so that the axial height of the cooling fan 21 is recessed into the thickness of the heat sink 23. This helps to reduce the axial size of the assembly formed by the cooling fan 21 and the heat sink 23, and reserves space for the arrangement of other components in the housing 10.

[0048] In an optional embodiment, the heat sink 232 has an air inlet 232a and an air outlet 232b. The air inlet 232a is formed on the air outlet side of the cooling fan 21, and the air outlet 232b is connected to the first guide section 22a, so that the heat sink 232 can form a closed or semi-closed flow channel with a rigid wall boundary. The air inlet 232a is located on the air outlet side of the cooling fan 21, which can guide the airflow discharged by the cooling fan 21 into the gas channel 23211 in the heat sink 232, so that the airflow generated by the cooling fan 21 can be forced to participate in convective heat transfer in the gas channel 23211 in the heat sink 232. The air outlet 232b is rigidly connected to the first guide section 22a, so that the airflow flowing through the gas channel 23211 can be guided into the guide pipe 22 and discharged from the air outlet 12 through the guide pipe 22.

[0049] In an optional embodiment, the heat sink 232 is provided with a plurality of sheet-like heat sinks 2321 spaced apart. A gas channel 23211 for gas flow is formed between adjacent heat sinks 2321. The first end of the gas channel 23211 is connected to the air outlet side, and the second end of the gas channel 23211 is connected to the first guide section 22a. This allows both sides of each heat sink 2321 on the heat sink 232 to be in direct contact with the flowing gas and participate in convective heat exchange. At the same time, the gas channel 23211 formed between two adjacent heat sinks is equivalent to an independent heat exchange pipe. Multiple gas channels 23211 can increase the contact area between the heat sink 2321 and the airflow, thereby improving the heat exchange capacity of the radiator 23.

[0050] In an optional embodiment, multiple heat sinks 2321 are arranged side by side and spaced apart along the extension direction of the heat sink 23, so that the total airflow discharged from the exhaust side of the cooling fan 21 can be evenly divided into multiple sub-airflows at the air inlet 232a of the heat sink 232. The airflows can flow through the gas channels 23211 between adjacent heat sinks 2321 respectively, thereby increasing the contact area between the airflow and the heat sinks 2321.

[0051] In one alternative embodiment, the heat sink 2321 is wavy. Compared to a flat heat sink 2321 with the same bottom area, the wavy heat sink 2321 not only increases its surface area in contact with airflow, improving heat dissipation efficiency, but also enhances the mechanical strength of the radiator 23, making it more resistant to vibration and impact. Alternatively, the heat sink 2321 is continuously bent. Compared to a flat heat sink 2321 with the same bottom area, the continuously bent heat sink 2321 not only increases its surface area in contact with airflow, improving heat dissipation efficiency, but also enhances the mechanical strength of the radiator 23, making it more resistant to vibration and impact.

[0052] In one alternative implementation, such as Figures 6 to 9 As shown, the radiator 23 is provided with a first mounting part 2322, and the first flow guide section 22a is provided with a second mounting part 222. The first flow guide section 22a is detachably mounted on the radiator 23 through the cooperation of the second mounting part 222 and the first mounting part 2322, so that the first flow guide section 22a can be firmly fixed on the radiator 23.

[0053] In an optional embodiment, the first assembly part 2322 includes a flange connection part disposed on the radiator 23, and the second assembly part 222 includes a connecting flange disposed on the first guide section 22a. The connecting flange is connected to the flange connection part, so that the first guide section 22a can be fixedly connected to the radiator 23.

[0054] In an optional embodiment, the first assembly part 2322 includes a fixing post disposed on the radiator 23, and the second assembly part 222 includes a fixing hole formed on the first guide section 22a. The position of the fixing hole corresponds to the position of the fixing post, so that the locking member can pass through the fixing hole and be threadedly connected to the fixing post, thereby realizing the fixed connection between the first guide section 22a and the radiator 23.

[0055] In an optional embodiment, one of the first assembly part 2322 and the second assembly part 222 is a snap-fit ​​part, and the other of the first assembly part 2322 and the second assembly part 222 is a slot part. The slot part and the snap-fit ​​part are engaged, so that the first flow guide section 22a can be fixedly connected to the heat sink 23.

[0056] In one alternative implementation, such as Figure 4 , Figures 6 to 9 As shown, the second guide section 22b is integrally formed with the first guide section 22a through injection molding, or the second guide section 22b is integrally connected with the first guide section 22a through secondary injection molding or overmolding, so as to achieve a continuous and seamless connection between the second guide section 22b and the first guide section 22a, and ensure the sealing between the second guide section 22b and the first guide section 22a.

[0057] In an optional embodiment, the second guide section 22b and the first guide section 22a are separate components connected to each other. This allows the first guide section 22a to ensure the stability of the airflow path and its resistance to deformation, while the second guide section 22b can flexibly route its path within the compact space inside the robot, absorb vibrations, and compensate for installation tolerances, thus balancing guide performance and assembly adaptability. Furthermore, the second guide section 22b and the first guide section 22a can be manufactured with independent molds and molding processes, eliminating the need for expensive secondary injection molding or overmolding, thereby reducing manufacturing complexity and scrap rate. During use and maintenance, since the second guide section 22b is typically more prone to aging, damage, or blockage, this application, through a detachable design, allows for the replacement of only the damaged second guide section 22b when it is damaged, avoiding the high costs associated with replacing the entire guide tube 22 and significantly extending the service life of the entire guide tube 22.

[0058] In an optional embodiment, the first flow guide section 22a is made of plastic, metal, or composite material. Making the first flow guide section 22a of plastic material not only significantly reduces its weight but also allows for injection molding, thus reducing the likelihood of electrical connection between the first flow guide section 22a and conductive components on the circuit board 31.

[0059] In an alternative embodiment, the second guide section 22b is made of silicone, rubber or thermoplastic elastomer, which allows the second guide section 22b to flexibly route within the compact space inside the robot, absorb vibration and compensate for installation tolerances. It complements the first guide section 22a, which is made of rigid material, and takes into account both the guiding performance and assembly adaptability of the guide tube 22.

[0060] In an optional embodiment, there are at least two guide pipes 22. One guide pipe 22 is connected between the air outlet side of the cooling fan 21 and the air outlet 12, and the other guide pipe 22 is connected between the air inlet side of the cooling fan 21 and the air inlet 11. It is used to guide the gas outside the housing 10 from the air inlet 11 to the air inlet side of the cooling fan 21.
