[0027] like Figure 1-6As shown, this embodiment discloses a robot body heat dissipation structure, including a torso shell 1, a heat dissipation component 2, and a fan component 3. Mounting positions 12 for mounting joint motor modules 4 are respectively constructed at the front and rear parts of the torso shell 1. The heat dissipation component 2 is mounted on the outer side wall of the torso shell 1. The fan component 3 is mounted on the outer side wall between at least one mounting position 12 and the heat dissipation component 2, and can draw in air located next to the heat dissipation component 2 and blow air onto the joint motor module 4 on that side mounting position 12. Specifically, the torso shell 1 is a hollow frame structure. Its outer wall has a flat mounting surface corresponding to the installation area of ​​the heat dissipation component 2. The flat mounting surface has a mounting part for connecting and fixing to the heat dissipation component 2. The heat dissipation component 2 can be detachably fixed to the corresponding position on the torso shell 1 through a fixing structure. The front of the torso shell 1 has a front mounting position 12, and the rear has a rear mounting position 12, used for installing the front joint motor module 4 and the rear joint motor module 4, respectively. The mounting position 12 for installing the joint motor module 4 forms a receiving cavity, into which the joint motor module 4 can be embedded. The fan assembly 3 is fixed on the outer wall between the receiving cavity and the heat dissipation component 2, so that the air inlet corresponds to the air outlet of the heat dissipation component 2, and the air outlet corresponds to the joint motor module 4. When working, after the fan assembly 3 starts, a negative pressure is formed at the air inlet; external air, under the action of negative pressure, passes through the heat dissipation component 2 and is drawn in by the fan, blown towards the joint motor module 4 in the receiving cavity to achieve cooling. This structure, through the coordinated operation of heat dissipation component 2 and fan component 3, forms a directional heat dissipation airflow circulation, which can simultaneously and efficiently cool the torso shell 1 and joint motor module 4, avoiding local overheating that could affect the robot's operational stability. The detachable installation method facilitates later maintenance and replacement, ensuring that the robot can maintain good performance even under long-term high-load operation.

[0028] In this embodiment, two sets of fan assemblies 3 can be arranged on both sides of the torso shell 1. Each set of fan assemblies 3 includes two fan assemblies 3 that blow air onto the front leg joint motor module 4 on the same side and the rear leg joint motor module 4 on the same side, respectively. The fan assembly 3 includes a cooling fan 31 installed on the outer wall of the torso shell 1 and a fan cover 32 covering the cooling fan 31. The fan cover 32 has an air outlet channel 321 on the side near the corresponding joint motor module 4. A joint motor module 4 is arranged on the front and rear sides of the torso shell 1. On the outer walls of both sides of the torso shell 1, and between the cooling assembly 2 and each skeleton motor module, a set of fan assemblies 3 is installed. One fan assembly is used to blow air onto the front leg joint motor module on the same side, and the other fan assembly is used to blow air onto the rear leg joint motor module on the same side. The fan assembly 3 includes a cooling fan 31 fixedly installed on the outer wall of the torso shell 1 and a fan cover 32 covering the cooling fan 31. The fan cover 32 adopts an airflow guiding design, with an air outlet channel 321 with a specific guiding angle on the side near the corresponding joint motor module 4, which is used to concentrate the cooling airflow to the heat dissipation surface of the target motor module. By setting independent fan units for the front and rear leg motors on the same side, precise directional heat dissipation of the limb joint motors is achieved, avoiding mutual airflow interference and significantly improving the cooling effect and uniformity of each joint motor module 4; the fan cover 32 design with airflow guiding channel can effectively constrain and guide the airflow direction and reduce airflow diffusion loss.

[0029] In this embodiment, a first air intake space of a predetermined height is constructed between the bottom of the cooling fan 31 and the outer wall of the body housing 1, and the outer wall and the bottom of the cooling fan 31 form a first air intake channel 33 around the side near the heat dissipation component 2. Air in the area surrounding the heat dissipation component 2 can be drawn into the bottom first air intake space through the first air intake channel 33 under the negative pressure generated when the cooling fan 31 is working, and then completely sucked in by the cooling fan 31 and accelerated and blown towards the corresponding joint motor module 4. Through the first air intake channel 33, air flowing through the heat dissipation component 2 can be actively extracted, realizing the effective utilization of cooling airflow and significantly improving the cooling potential and heat dissipation efficiency of the airflow entering the motor module; the cooperation between the first air intake space and the directional air intake channel effectively avoids airflow short-circuiting and turbulence, ensuring smooth air intake and stable airflow.

[0030] In this embodiment, the cooling fan 31 is a turbine cooling fan 31. The air inlet of the turbine cooling fan 31 is oriented towards the outer wall, and the air outlet 34 of the turbine cooling fan 31 is directly aligned with and faces the air outlet channel 321 opened on the fan cover 32. This orientation configuration allows the turbine cooling fan 31 to efficiently draw airflow from the first air intake space and, through its unique guiding effect, force the airflow towards the air outlet channel 321. In some preferred embodiments, the turbine cooling fan can be an FB04010S12H blower or other 5010 type turbine blowers. By selecting a turbine cooling fan, the airflow direction can be effectively controlled, avoiding the problem of scattered airflow and the inability to concentrate the airflow towards the air intake side when using traditional axial fans.

[0031] In another specific embodiment, when a turbine cooling fan is used, the air inlet of the turbine cooling fan is installed facing the top plate of the fan shroud, and the air outlet of the turbine cooling fan faces the air outlet channel. At this time, a second air intake space is constructed between the turbine cooling fan and the inner side of the top plate of the fan shroud; a second air intake channel is opened on the side of the fan shroud near the heat dissipation component. Air near the heat dissipation component can be drawn into the first air intake space through the second air intake channel by the cooling fan, and then drawn in by the cooling fan and blown towards the corresponding joint motor module through the air outlet channel. Because the air outlet of the turbine cooling fan is perpendicular to the fan shaft, the air inlet of the turbine cooling fan can be installed facing the outer wall of the torso housing as described in the previous embodiments, allowing air to enter between the turbine cooling fan and the outer wall of the torso housing; or it can be installed facing the top plate of the fan shroud, i.e., in reverse, as described in this embodiment, allowing air to enter between the turbine cooling fan and the top plate of the fan shroud, achieving a similar air intake effect.

[0032] In this embodiment, the fan shroud 32 has a second air intake channel 35 on the side near the heat dissipation component 2. The arrangement of this channel forms a diversified air intake path: air located near the heat dissipation component 2 can enter the first air intake space through the second air intake channel 35 under the strong negative pressure generated by the cooling fan 31; or air located near the heat dissipation component 2 can enter the first air intake space by sequentially passing through the second air intake channel 35 and the first air intake channel 33 under the attraction of the cooling fan 31, and finally be sucked in by the cooling fan 31 and blown towards the air outlet channel 321. By adding a second air intake channel 35, a diversified air intake system with dual or even multiple channels is constructed, significantly increasing the total air intake area and air volume. This effectively avoids the decrease in heat dissipation performance caused by partial blockage of a single channel, thus improving system reliability. The second air intake channel 35 provides a shorter and more direct suction path for the hot air flowing above the heat dissipation component 2, enabling timely discharge of hot air accumulated near the heat dissipation component 2, preventing hot air backflow, improving the cooling efficiency of the heat dissipation component 2 itself, and thus indirectly reducing the heat source. The dual-channel design gives the system stronger environmental adaptability, allowing for flexible adjustment of the air intake strategy based on internal heat generation and external environment, achieving a dynamic optimization balance between heat dissipation efficiency and energy consumption.

[0033] In this embodiment, an outwardly protruding edge strip 13 is constructed on the outer wall of the torso housing 1 near the mounting position 12. The vertical height of the edge strip 13 is designed such that its height is not lower than the bottom edge of the cooling fan 31 and not higher than the bottom edge of the air outlet channel 321 on the fan cover 32. This effectively prevents hot air from the joint motor module area from being drawn into the cooling fan, while not obstructing the air outlet channel from blowing air to the joint motor module for heat dissipation.

[0034] In this embodiment, the fan cover 32 has an outwardly protruding first mounting base 322 on the side with the air outlet channel 321. The first mounting base 322 is detachably and fixedly connected to the upper part of the edge strip by a fastener. This fastener can be a commonly used screw, thereby firmly installing the fan cover 32 onto the outer wall of the body shell 1. The direct fastening connection between the first mounting base 322 and the upper part of the edge strip 13 provides an additional and solid support point for the fan cover 32, significantly enhancing the structural stability and vibration resistance of the entire fan assembly 3 during robot movement, and preventing loosening or failure of the connection due to long-term vibration.

[0035] In this embodiment, second mounting bases 14 are respectively constructed at the upper and lower ends of the first air intake channel 33 on the outer side wall of the body shell 1. Correspondingly, connection holes 323 are provided on both sides of the second air intake channel 35 of the fan cover 32. Fasteners are connected to the second mounting base 14 in sequence through the connection holes 323 on the fan cover 32, the mounting holes 11 of the cooling fan 31, and finally locked to the second mounting base 14 on the outer side wall, thereby achieving a stable connection between the three. In addition, the second air intake channel 35 and the first air intake channel 33 on the same fan assembly 3 are arranged in a stacked manner in space. The stacked arrangement of the second air intake channel 35 and the first air intake channel 33 optimizes the spatial layout of the air intake, maximizes the effective air intake area within a limited projected area, and improves the air intake efficiency.

[0036] In this embodiment, the heat dissipation assembly 2 is composed of multiple metal heat sinks 21. These metal heat sinks 21 extend laterally along the outer wall of the body shell 1 and are arranged in parallel to form a dense fin array structure. Heat dissipation channels are formed between adjacent heat sinks 21. The multiple parallel heat sinks 21 significantly increase the effective heat dissipation surface area in contact with the air, greatly improving the heat exchange efficiency of the heat dissipation assembly 2 in a limited space, and can quickly dissipate the heat inside the shell to the surrounding environment. The laterally parallel arrangement of the heat sinks 21 is adapted to the airflow direction generated by the fan assembly 3, forming a parallel flow channel with low flow resistance, which is conducive to the smooth passage of air through the fin gaps, reduces wind pressure loss, and thus improves the effect of forced convection heat dissipation.

[0037] In this embodiment, the top of the metal heat sink 21 near the fan assembly 3 is provided with a specific inclined portion 211. This inclined portion is precisely constructed such that the top of the metal heat sink 21 slopes from the end near the fan assembly 3 toward the direction away from the fan assembly 3 and away from the outer wall of the body housing 1. This forms a guide slope with a compound angle. This compound inclined surface can efficiently guide the airflow drawn in by the fan assembly 3, smoothly guiding the airflow to the root of the heat sink 21 array and the internal flow channel. While ensuring that the heat sink has a sufficient heat dissipation area, it reduces the obstruction of the airflow attracted by the fan at the end of the heat sink near the fan. This can significantly reduce the eddies and resistance losses caused by the impact at the inlet of the heat sink 21, and improve the intake efficiency and the uniformity of the flow field.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.

[0039] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
