Description

Technical Field

[0001] This utility model relates to the field of robot heat dissipation technology, and in particular to a body heat dissipation structure and a quadruped robot. Background Technology

[0002] Quadruped robots possess high flexibility and stability, easily handling complex and varied terrains such as mountains, forests, ruins, and narrow passages. Furthermore, with continuous advancements in motion control technology, quadruped robots can now perform complex actions such as rapid running, jumping, and climbing, demonstrating excellent dynamic motion performance.

[0003] Currently, the main factors affecting the stability of quadruped robots are the walking control algorithm and the mechanical performance of the robot body. Among the mechanical performance of the robot body, the problem of motor heat dissipation is particularly prominent. If the motor overheats, the quadruped robot will enter a self-protection state and stop working. It may even cause problems such as burnt-out circuits, which will greatly affect its performance and stability. Utility Model Content

[0004] Therefore, it is necessary to provide a body heat dissipation structure and a quadruped robot to address the problem of motor heat dissipation in existing quadruped robots.

[0005] The technical solution is as follows:

[0006] On the one hand, a heat dissipation structure for the chassis is provided, including:

[0007] The main body of the unit is provided with a first mounting cavity and a first air inlet and an air outlet communicating with the first mounting cavity;

[0008] The motor is installed in the first mounting cavity, and together with the inner wall of the first mounting cavity, a first heat dissipation channel and a second heat dissipation channel are formed. The first heat dissipation channel and the second heat dissipation channel are arranged along the circumference of the motor and are both connected to the first air inlet and the air outlet. The path length of the first heat dissipation channel is greater than the path length of the second heat dissipation channel, and the wind resistance of the first heat dissipation channel is less than the wind resistance of the second heat dissipation channel.

[0009] A first airflow drive component is installed on the main body of the unit and is used to drive the gas in the first heat dissipation channel and the second heat dissipation channel to flow toward the air outlet.

[0010] The technical solution will be further explained below:

[0011] In one embodiment, there are two first air inlets, which are respectively located on opposite sides of the main body. Two motors are installed in the first mounting cavity. The two motors and the inner wall of the first mounting cavity form a first heat dissipation channel and a second heat dissipation channel. One end of the two first heat dissipation channels and one end of the two second heat dissipation channels are connected to the air outlet. The other end of the two first heat dissipation channels and the other end of the two second heat dissipation channels are respectively connected to the two first air inlets.

[0012] In one embodiment, the air outlet is located at the bottom of the main body of the unit, and the first airflow drive component is installed at the air outlet.

[0013] In one embodiment, the inner wall of the first heat dissipation channel on the side away from the motor is provided with a first guide portion, and the inner wall of the second heat dissipation channel on the side away from the motor is provided with a second guide portion, wherein the distance between the first guide portion and the motor is greater than the distance between the second guide portion and the motor.

[0014] In one embodiment, the main body of the fuselage is further provided with a second air inlet, which is located between the first air inlet and the air outlet and is connected to the first heat dissipation channel.

[0015] In one embodiment, the heat dissipation structure of the fuselage further includes a second airflow drive component, which is installed at the second air inlet and is used to drive gas to flow toward the air outlet.

[0016] In one embodiment, the main body of the fuselage is further provided with a second mounting cavity, a third mounting cavity and a third heat dissipation channel located between the second mounting cavity and the third mounting cavity, and the fuselage heat dissipation structure further includes a battery installed in the second mounting cavity, a control motherboard installed in the third mounting cavity and a third airflow drive component installed in the third heat dissipation channel.

[0017] In one embodiment, the inner wall of the third mounting cavity is provided with a heat dissipation port communicating with the third heat dissipation channel, and the body heat dissipation structure further includes a heat dissipation component, which is installed on the heat dissipation port to seal the heat dissipation port.

[0018] In one embodiment, the heat sink has at least one heat sink fin on the side facing away from the control motherboard, and each heat sink fin extends into the third heat dissipation channel and is spaced apart along the extension direction perpendicular to the third heat dissipation channel.

[0019] On the other hand, a quadruped robot is provided, including the aforementioned body heat dissipation structure. The two ends of the main body are provided with the first mounting cavity, the first air inlet and the air outlet. The number of motors is four, and the four motors are respectively installed in two of the first mounting cavities.

[0020] In the above embodiments, the body heat dissipation structure and quadruped robot, during use, are driven by a first airflow drive component that directs the gas in the first and second heat dissipation channels toward the air outlet. This allows gas from the external environment to enter the first air inlet. The gas at the first air inlet is then split and flows through the first and second heat dissipation channels to the air outlet. During its flow within the first and second heat dissipation channels, the gas carries away the heat generated by the motor. The heated gas converges at the air outlet and is then discharged into the external environment, thus cooling the motor. Furthermore, because the path length of the first heat dissipation channel is greater than that of the second heat dissipation channel, the air resistance of the first heat dissipation channel is designed to be lower than that of the second heat dissipation channel. This results in a greater airflow entering the first heat dissipation channel than the second, allowing for uniform heat dissipation on all four sides of the motor. This improves the heat dissipation performance of the body heat dissipation structure, ensuring the quadruped robot can operate continuously and stably. Attached Figure Description

[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] like Figure 1 and Figure 2 As shown, in one embodiment, a fuselage heat dissipation structure 10 is provided, including a fuselage body 100, a motor 200, and a first airflow drive component 300. The fuselage body 100 has a first mounting cavity 110 and a first air inlet 120 and an air outlet 130 communicating with the first mounting cavity 110. The motor 200 is mounted within the first mounting cavity 110, forming a first heat dissipation channel 410 and a second heat dissipation channel 420 with the inner wall of the first mounting cavity 110. The first heat dissipation channel 410 and the second heat dissipation channel 420 are arranged circumferentially along the motor 200 and are both connected to the first air inlet 120 and the air outlet 130. The path length of the first heat dissipation channel 410 is greater than the path length of the second heat dissipation channel 420, and the air resistance of the first heat dissipation channel 410 is less than the air resistance of the second heat dissipation channel 420. The first airflow drive component 300 is mounted on the fuselage body 100 and is used to drive the gas in the first heat dissipation channel 410 and the second heat dissipation channel 420 to flow towards the air outlet 130.

[0034] In the above embodiment, the body heat dissipation structure 10, when in use, the first airflow driving component 300 drives the gas in the first heat dissipation channel 410 and the second heat dissipation channel 420 to flow toward the air outlet 130, so that the gas in the external environment enters the first air inlet 120. The gas at the first air inlet 120 is split and flows to the air outlet 130 through the first heat dissipation channel 410 and the second heat dissipation channel 420 respectively. During the process of the gas flowing in the first heat dissipation channel 410 and the second heat dissipation channel 420, it will carry away the heat generated by the motor 200. The gas with heat is gathered at the air outlet 130 and discharged to the external environment through the air outlet 130, thereby achieving heat dissipation for the motor 200. In addition, since the path length of the first heat dissipation channel 410 is greater than that of the second heat dissipation channel 420, the wind resistance of the first heat dissipation channel 410 is designed to be smaller than that of the second heat dissipation channel 420. This results in the air volume entering the first heat dissipation channel 410 being greater than that entering the second heat dissipation channel 420, thereby enabling the motor 200 to dissipate heat evenly on all four sides of its circumference and improving the heat dissipation performance of the body heat dissipation structure 10.

[0035] The number and position of the first mounting cavity 110, the number and position of the first air inlet 120, the number and position of the air outlet 130, and the number of motors 200 can all be flexibly adjusted according to actual usage needs.

[0036] like Figure 2 As shown, optionally, there are two first air inlets 120. The two first air inlets 120 are respectively located on opposite sides of the main body 100. Two motors 200 are installed in the first mounting cavity 110. Each of the two motors 200 forms a first heat dissipation channel 410 and a second heat dissipation channel 420 with the inner wall of the first mounting cavity 110. One end of each of the two first heat dissipation channels 410 and one end of each of the two second heat dissipation channels 420 communicates with an air outlet 130. The other ends of each of the two first heat dissipation channels 410 and the two second heat dissipation channels 420 communicate with the two first air inlets 120 respectively. Thus, the two motors 200 are installed in the same first mounting cavity 110, allowing them to share the first airflow drive component 300, saving space and facilitating a compact and integrated design of the body heat dissipation structure 10.

[0037] The first airflow drive component 300 can be configured as a cooling fan, blower, or other structure capable of driving gas flow. The first airflow drive component 300 can be directly installed at the first air inlet 120 or air outlet 130, or it can be installed on the main body 100 and connected to the first air inlet 120 or air outlet 130. The number of first airflow drive components 300 can be flexibly adjusted according to actual usage needs. For example, when there is one first airflow drive component 300, it is installed at the air outlet 130; when there are two first airflow drive components 300, they are installed at the two first air inlets 120 respectively; when there are three first airflow drive components 300, they are installed at the two first air inlets 120 and one air outlet 130 respectively.

[0038] like Figure 2 As shown, optionally, the air outlet 130 is located at the bottom of the main body 100, and the first airflow drive component 300 is installed at the air outlet 130. In this way, by adopting a downward exhaust method, the main body 100 is located above the first airflow drive component 300, which can prevent water from entering the first airflow drive component 300 and improve the reliability of the heat dissipation structure 10.

[0039] It should be noted that the path length of the first heat dissipation channel 410 refers to the length of the first heat dissipation channel 410 along its own extending direction. The path length of the second heat dissipation channel 420 refers to the length of the second heat dissipation channel 420 along its own extending direction.

[0040] The air resistance of the first heat dissipation channel 410 can be controlled by adjusting its cross-sectional dimensions, by incorporating a wind-blocking structure (such as a wind-blocking protrusion) within the first heat dissipation channel 410, or by other methods that can adjust air resistance. Similarly, the air resistance of the second heat dissipation channel 420 can be controlled by adjusting its cross-sectional dimensions, by incorporating a wind-blocking structure within the second heat dissipation channel 420, or by other methods that can adjust air resistance.

[0041] like Figure 2As shown, in one embodiment, the inner wall of the first heat dissipation channel 410 on the side away from the motor 200 is provided with a first airflow guide 430. The inner wall of the second heat dissipation channel 420 on the side away from the motor 200 is provided with a second airflow guide 440. The distance between the first airflow guide 430 and the motor 200 is greater than the distance between the second airflow guide 440 and the motor 200. Thus, by adjusting the distance between the first airflow guide 430 and the motor 200, the air resistance of the first heat dissipation channel 410 can be adjusted, and by adjusting the distance between the second airflow guide 440 and the motor 200, the air resistance of the second heat dissipation channel 420 can be adjusted. The operation is simple and convenient, and the practicality of the body heat dissipation structure 10 can be improved.

[0042] Specifically, in this embodiment, the first guide section 430 is configured as a first arc-shaped guide plate, and the second guide section 440 is configured as a second arc-shaped guide plate. The extension directions of both the first and second arc-shaped guide plates are the same as the circumferential direction of the motor 200. Thus, the arc-shaped design of both the first guide section 430 and the second guide section 440 can guide the gas flow towards the air outlet 130, preventing turbulence and eddies in the gas within the first and second heat dissipation channels 410 and 420. This ensures that the gas can smoothly pass through the first and second heat dissipation channels 410 and carry away the heat generated by the motor 200, improving the reliability of the body heat dissipation structure 10.

[0043] It should be noted that the distances between the first airflow guide 430 and the motor 200, and between the second airflow guide 440 and the motor 200, can be flexibly adjusted according to actual usage needs. For example, the distances between the first airflow guide 430 and the motor 200, and between the second airflow guide 440 and the motor 200, can be flexibly adjusted according to the overall dimensions of the heat dissipation structure 10 and the dimensions and power consumption of the motor 200.

[0044] Specifically, in this embodiment, the distance between the first guide section 430 and the motor 200 can be set to 4mm to 6.5mm; the distance between the second guide section 440 and the motor 200 can be set to 0mm to 2mm.

[0045] It should be noted that when the distance between the second air guide 440 and the motor 200 is 0mm, the second heat dissipation channel 420 cannot allow gas to pass through, and all the gas at the first air inlet 120 flows to the air outlet 130 through the first heat dissipation channel 410. In this way, while taking into account the heat dissipation of the motor 200, the stability of the motor 200 support can be ensured.

[0046] like Figure 3As shown, in one embodiment, the fuselage body 100 is further provided with a second air inlet 140. The second air inlet 140 is located on the airflow path and is connected to the first heat dissipation channel 410. Thus, the arrangement of the second air inlet 140 increases the airflow speed between the second air inlet 140 and the air outlet 130. According to Bernoulli's principle, the pressure between the second air inlet 140 and the air outlet 130 is correspondingly reduced, forming a negative pressure zone. This causes more gas in the external environment to pass through the first air inlet 120 and be diverted into the first heat dissipation channel 410 and the second heat dissipation channel 420, accelerating the transfer and dissipation of heat, effectively enhancing the convective heat transfer effect of the air, and improving the heat dissipation rate of the fuselage heat dissipation structure 10. In addition, based on the fuselage heat dissipation structure 10 utilizing Bernoulli's principle, greater airflow can be generated within the first heat dissipation channel 410 and the second heat dissipation channel 420, enabling the first airflow drive component 300 to achieve efficient heat dissipation with lower energy consumption. That is, while achieving the same heat dissipation effect, the power of the first airflow drive component 300 can be reduced, thereby reducing the noise generated by the first airflow drive component 300 during operation and improving the practicality of the fuselage heat dissipation structure 10.

[0047] Specifically, in this embodiment, the second air inlet 140 being located on the airflow path means that the second air inlet 140 is located on the airflow path between the first air inlet 120 and the air outlet 140.

[0048] Specifically in this embodiment, the second air inlet 140 is located at the top of the main body 100, between the two motors 200, and directly above the air outlet 130.

[0049] Optionally, the fuselage heat dissipation structure 10 also includes a second airflow drive component. The second airflow drive component is installed at the second air inlet 140 and is used to drive the gas to flow toward the air outlet 130. In this way, the second airflow drive component can further accelerate the airflow speed between the second air inlet 140 and the air outlet 130, further enhance the convective heat transfer effect of the air, and improve the heat dissipation performance of the fuselage heat dissipation structure 10.

[0050] The second airflow drive component can be configured as a cooling fan, a blower, or other structure capable of driving gas flow.

[0051] like Figure 4 and Figure 5As shown, in one embodiment, the main body 100 further includes a second mounting cavity 150, a third mounting cavity 160 spaced apart, and a third heat dissipation channel 170 located between the second mounting cavity 150 and the third mounting cavity 160. The body heat dissipation structure 10 also includes a battery 500 installed in the second mounting cavity 150, a control motherboard 600 installed in the third mounting cavity 160, and a third airflow drive component 700 installed in the third heat dissipation channel 170. Thus, the battery 500 and the control motherboard 600 share the third heat dissipation channel 170, achieving effective heat dissipation for both the battery 500 and the control motherboard 600, while also facilitating the integrated design of the body heat dissipation structure 10.

[0052] The third airflow drive component 700 can be configured as a cooling fan, blower, or other structure capable of driving gas flow; the battery 500 can be connected to the third heat dissipation channel 170 through heat transfer components such as a heat transfer plate.

[0053] Specifically, in this embodiment, there are two third airflow drive components 700, which are respectively installed at the air inlet and air outlet of the third heat dissipation channel 170. This further improves the heat dissipation performance of the chassis heat dissipation structure 10.

[0054] like Figure 4 and Figure 5 As shown, the inner wall of the third mounting cavity 160 is further provided with a heat dissipation vent 161 communicating with the third heat dissipation channel 170. The chassis heat dissipation structure 10 also includes a heat sink 800, which is installed at the heat dissipation vent 161 to seal the heat dissipation vent 161. Thus, since the heat generated by the control motherboard 600 is greater than that generated by the battery 500, the heat sink 800 is installed at the heat dissipation vent 161, and the control motherboard 600 can be in close contact with the heat sink 800, thereby accelerating the heat dissipation efficiency of the control motherboard 600 and improving the reliability of the chassis heat dissipation structure 10.

[0055] The heat sink 800 can be configured as a heat sink plate, heat sink cover, heat sink fin, or other heat dissipation structure.

[0056] In this specific embodiment, the heat sink 800 is a separately detachable component. Thus, waterproofing only needs to be applied to the contact surface between the heat sink 800 and the third heat dissipation channel 170, which simplifies manufacturing, enhances the waterproofing method, and improves the practicality of the chassis heat dissipation structure 10.

[0057] like Figure 4 and Figure 5As shown, optionally, the heat sink 800 has at least one heat dissipation fin 810 on the side facing away from the control motherboard 600. Each heat dissipation fin 810 extends into the third heat dissipation channel 170 and is spaced apart along the extension direction perpendicular to the third heat dissipation channel 170. In this way, the heat dissipation fins 810 can further increase the heat dissipation area of ​​the third heat dissipation channel 170, thereby improving the heat dissipation performance of the chassis heat dissipation structure 10.

[0058] like Figure 2 , Figure 6 and Figure 7 As shown, in one embodiment, a quadruped robot 1 is also provided, including the body heat dissipation structure 10 of any of the above embodiments. The main body 100 has a first mounting cavity 110, a first air inlet 120, and an air outlet 130 at both ends. There are four motors 200, each mounted in one of the two first mounting cavities 110. In this way, all four motors 200 can receive uniform and reliable heat dissipation, ensuring that the quadruped robot 1 can operate continuously and stably.

[0059] It should be noted that the heat dissipation structure 10 can also be applied to cleaning robots, delivery robots or other equipment.

[0060] Specifically, in this embodiment, the motor 200 can be configured as a side-swing motor. The side-swing motor is located inside the main body 100 and can cooperate with the main body 100 and the first airflow drive component 300 to dissipate heat, ensuring that the side-swing motor will not overheat during long-term operation and improving the reliability of the quadruped robot 1.
