[0037] To make the above objects, features, and advantages of the present application more apparent and understandable, the following describes the specific embodiments of the present application in detail with reference to the accompanying drawings. Many specific details are set forth in the following description to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0038] In the description of the present application, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. These are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present application.

[0039] In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of these features. In the description of the present application, "a plurality" means at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0040] In the present application, unless otherwise clearly specified and limited, the terms "mounted", "connected", "coupled", "fixed", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0041] In the present application, unless otherwise clearly specified and limited, the first feature being "on" or "under" the second feature can be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over", and "on top of" the second feature can be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature.

The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation.

[0043] The operating conditions of the end load of the robot vary in different application scenarios. Moreover, as the load demand of the robot 10 increases and the operation accuracy requirement becomes higher and higher, it is required that its motor has a higher power to meet the necessary motion capabilities such as sufficient torque, speed, and acceleration provided by the robot joints. At the same time, the installation position and narrow space of the motor and its transmission mechanism inside the robot require it to have a more compact and lightweight structure. High power and small space make the heat generation and heat dissipation of the robot motor more severe than those in other application scenarios of the motor. The insulating materials and permanent magnets in the motor are more sensitive to temperature changes. Excessive temperature rise will cause demagnetization of the permanent magnets and failure of the insulating materials, thereby reducing the working performance and lifespan of the motor. Therefore, the temperature rise and heat dissipation of the robot motor have become the key issues restricting the application and development of the robot motor.

[0044] To solve the problems of low heat dissipation efficiency and single heat dissipation method for the motor inside the robot in the related art, the present application provides a robot to improve the heat dissipation efficiency of the motor.

[0045] Refer to Figure 1 As shown, the robot 10 provided by the present application includes a housing 2, a motor body 1, and a heat conduction layer group 11. The housing 2 defines an accommodation cavity. The motor body 1 is disposed in the accommodation cavity. The heat conduction layer group 11 is disposed between the housing 2 and the motor body 1. And the side of the heat conduction layer group 11 facing the housing 2 is in contact with the inner wall of the housing 2, and the side of the heat conduction layer group 11 facing the motor body 1 is in contact with the side wall of the motor body 1. The inner wall of the housing 2 is opposite to the side wall of the motor body 1. The heat conduction layer group accelerates the heat conduction between the motor body 1 and the housing 2 of the robot 10, and improves the heat dissipation efficiency of the motor body 1.

[0046] In some embodiments, the heat conduction layer group 11 includes multiple heat conduction layers stacked between the housing 2 and the motor body 1. The multiple heat conduction layers are disposed between the bottom wall of the housing 2 and the side wall of the motor body 1, wherein the side wall of the motor body 1 faces the bottom wall of the housing 2. In some embodiments, the multiple heat conduction layers can also be disposed between any inner side wall or inner top wall of the housing 2 and any peripheral wall, upper top wall or lower bottom wall of the motor body 1, as long as it is ensured that the opposite sides of the multiple heat conduction layers are in contact with the motor body 1 and the housing 2 respectively, so as to increase the heat conduction cross-sectional area of the multiple heat conduction layers and achieve efficient heat conduction between the motor body 1 and the housing 2. There is no limitation here.

[0047] Continuing to refer to Figure 1 , the multiple heat conduction layers include a first heat conduction layer 7 and a second heat conduction layer 6.

[0048] In some embodiments, a second heat conduction layer 6 is provided between the first heat conduction layer 7 and the motor body 1. The side of the first heat conduction layer 7 facing away from the second heat conduction layer 6 is in contact with the inner wall of the housing 2, and the side of the second heat conduction layer 6 facing away from the first heat conduction layer 7 is in contact with the side wall of the motor body 1, so as to improve the heat conduction efficiency between the motor body 1 and the housing 2 through the first heat conduction layer 7 and the second heat conduction layer 6.

[0049] In some embodiments, a second heat conduction layer 6 is provided between the first heat conduction layer 7 and the housing 2. The side of the first heat conduction layer 7 facing away from the second heat conduction layer 6 is in contact with the side wall of the motor body 1, and the side of the second heat conduction layer 6 facing away from the first heat conduction layer 7 is in contact with the inner wall of the housing 2, so as to improve the heat conduction efficiency between the motor body 1 and the housing 2.

[0050] In some embodiments, it can also be set that a second heat conduction layer 6 is provided on both the side of the first heat conduction layer 7 facing the housing 2 and the side of the first heat conduction layer 6 facing the motor body 1. One side of one of the two second heat conduction layers 6 is in contact with the first heat conduction layer 7, and the other side is in contact with the inner wall of the housing 2. One side of the other of the two second heat conduction layers 6 is in contact with the first heat conduction layer 7, and the other side is in contact with the side wall of the motor body 1. Second heat conduction layers 6 are provided on both sides of the first heat conduction layer 6 relative to the housing 2 and the motor body 1. The heat dissipated by the motor body 1 can be quickly conducted to the housing 2 through the second heat conduction layer 6 - the first heat conduction layer 7 - the second heat conduction layer 6, accelerating the heat conduction between the motor body 1 and the housing 2.

[0051] It can be understood that a first heat-conducting layer 7 is provided between the motor body 1 and the housing 2. The second heat-conducting layer 6 can be provided between the first heat-conducting layer 7 and the motor body 1, or the second heat-conducting layer 6 can also be provided between the first heat-conducting layer 7 and the housing 2. Two second heat-conducting layers 6 can also be provided, and the two second heat-conducting layers 6 are respectively provided on both sides of the first heat-conducting layer 7, that is, one of the two second heat-conducting layers 6 is provided between the first heat-conducting layer 7 and the motor body 1, and the other of the two second heat-conducting layers 6 is provided between the first heat-conducting layer 7 and the housing 2.

[0052] In some embodiments, the first heat-conducting layer 7 includes a metal heat conductor, and the second heat-conducting layer 6 includes a flexible heat-conducting medium. That is, the first heat-conducting layer 7 can select a metal material with a higher thermal conductivity, such as metals and alloys such as aluminum and copper. It is arranged in the form of a metal heat-conducting layer and laid between the motor body 1 and the housing 2. The heat-conducting path has a shorter distance and a larger cross-sectional area, which can greatly improve the heat dissipation efficiency. The material of the second heat-conducting layer 6 is selected as a flexible heat-conducting medium, such as a silica gel pad or silicone grease, so that it serves as a buffer area between the first heat-conducting layer 7 and the inner surface of the motor body 1 and / or the housing 2 of the robot 10. After being pressed, the second heat-conducting layer 6 can produce a certain deformation, which can fill the gaps between the motor body 1 and the first heat-conducting layer 7 and between the first heat-conducting layer 7 and the inner surface of the housing 2, thereby improving the heat dissipation efficiency.

[0053] In some embodiments, both sides of the second heat-conducting layer 6 have a certain viscosity, which plays a role in preventing the first heat-conducting layer 7 from moving, and can also play a role in adhering to the first heat-conducting layer 7, adjusting the gap between the first heat-conducting layer 7 and the inner surface of the motor body 1 and / or the housing 2 of the robot 10, and filling the contact gap, so as to further improve the heat dissipation efficiency.

[0054] In some embodiments, the size of the side surface of the heat-conducting layer group 11 facing the motor body 1 or the housing 2 is similar to the size of the corresponding side surface of the motor body 1 or the housing 2, so as to be able to improve the contact area between the heat-conducting layer group 11 and the motor body 1 or the housing 2 as much as possible, and thus improve the heat dissipation efficiency.

[0055] The combination operation between the heat-conducting layer group 11 of the present application and the housing 2 and the motor body 1 is simple. The heat-conducting layer group 11 is attached to the side of the housing 2 or the motor body 1 facing each other, and then pressed tightly between the motor and the housing 2, which reduces the process complexity of installation and debugging and is beneficial to improving production efficiency.

[0056] Refer to Figure 2As shown, the first heat-conducting layer 7 is provided with a plurality of first heat-dissipating portions 7b, and the first heat-dissipating portions 7b are provided on the peripheral side of the first heat-conducting layer 7. The peripheral side of the first heat-conducting layer 7 is an axial side of the first heat-conducting layer 7 provided between the motor body 1 and the housing 2. In some embodiments, the plurality of first heat-dissipating portions 7b are provided as a grid structure provided on the peripheral side of the first heat-conducting layer 7, which can increase the contact area between the first heat-conducting layer 7 and the air in the accommodating cavity, and improve the heat convection area between the air in the accommodating cavity and the motor body 1 and the housing 2, thereby improving the heat dissipation efficiency. In some embodiments, the first heat-dissipating portion 7b can be integrally formed on the first heat-conducting layer 7, and can also be formed separately from the first heat-conducting layer 7 and then spliced ​​together, such as Figure 2 The layer body 7a and the first heat dissipation portion 7b can be formed separately and then the two can be spliced ​​together.

[0057] It can be understood that if the distance between the motor body 1 and the shell 2 is relatively far, and the size of the first heat-conducting layer 7 along the stacking direction of the heat-conducting layer group 11 is relatively large, then multiple first heat dissipation parts 7b can be set on the first heat-conducting layer 7. If the distance between the motor body 1 and the shell 2 is relatively close, then the first heat dissipation part 7b may not be set, and there is no limitation here.

[0058] In some embodiments, the plurality of first heat dissipation portions 7b may be configured as structures of different forms such as protrusions, groove structures, rib structures or holes to increase the contact area between the first heat conducting layer 7 and the air in the accommodating cavity.

[0059] like Figure 3 The robot 10 further includes at least one heat sink 8, which is disposed on the end surface of the motor body 1 away from the heat-conducting layer group 11 and / or on the peripheral side of the motor body 1, that is, the heat sink 8 can be disposed on a single side of the motor body 1 or wrap multiple sides of the motor body 1. The heat sink 8 can improve the efficiency of heat dissipation from the motor body 1 to the air in the accommodating cavity. The heat sink 8 is fixed to the motor body 1 by screws and fits with the motor body 1. A soft heat-conducting medium can also be used to fill the gap between the heat sink 8 and the motor body 1 to achieve the effect of filling the gap and further improve the heat dissipation efficiency.

[0060] In some embodiments, the heat sink 8 can be made of metal materials with high thermal conductivity, such as aluminum, copper and other metals and alloys.

[0061] In some embodiments, a plurality of second heat dissipation parts 8a are provided on the side of the heat dissipation member 8 facing away from the motor body 1, and the second heat dissipation parts 8a are provided on the heat dissipation member 8. The plurality of second heat dissipation parts 8a can be provided with a grid structure similar to the plurality of first heat dissipation parts 7b, or can be provided with different forms of structures such as protrusions, holes, grooves, etc. to increase the contact area between the heat dissipation member 8 and the air in the accommodating cavity.

[0062] See also Figure 4As shown, the heat sink 8 is provided with a cable binding plate 8b, which can be set to a metal heat conductor material, such as aluminum, copper and other metals and alloys, to further improve heat conduction and heat dissipation effect, and the cable binding plate 8b is provided with a plurality of mounting holes for fixing the motor body 1 and the cables in the accommodating cavity, improving the regularity of the cables and preventing the mess of the cables from affecting the heat dissipation efficiency. The heat sink 8 is combined with the cable binding plate 8b, and the cables are fixed through the mounting holes. While improving the heat dissipation effect, it saves unnecessary materials for fixing other cables, saves energy, and simplifies the process flow, without the need to set other cable fixing parts.

[0063] See also Figure 5 As shown, the inner surface of the shell 2 is provided with a plurality of third heat dissipation parts 2a, and the third heat dissipation parts 2a are provided to increase the heat convection efficiency between the air in the housing chamber of the robot 10 and the inner surface of the housing 2 of the robot 10. The third heat dissipation parts 2a can be provided as a grid structure similar to the plurality of first heat dissipation parts 7b, or can be provided with different forms of structures such as protrusions, holes, grooves, etc. to increase the contact area between the inner surface of the shell 2 and the air in the housing chamber. In some embodiments, the third heat dissipation parts 2a can be processed integrally with the housing 2 of the robot 10, or can be processed separately and assembled to the housing 2 of the robot 10.

[0064] Continue reading Figure 5 The robot 10 further includes a transmission member 3, which is disposed at the output end of the motor body 1. The transmission member 3 is provided with a plurality of blades 3b, and the transmission member 3 is configured to drive the blades 3b to rotate as the motor body 1 is driven to increase the gas flow rate in the accommodating chamber.

[0065] The robot 10 further includes a reducer 5 and a synchronous belt 4 , which are connected to the reducer 5 and the motor body 1 through the synchronous belt 4 and the transmission member 3 to achieve transmission connection between the reducer 5 and the motor body 1 .

[0066] In some embodiments, the transmission member 3 includes two pulleys, one of which is arranged at the output end of the motor body 1, and the other is arranged at the input end of the reducer 5, and the synchronous belt 4 is connected between the two pulleys to realize the external drive output of the motor body 1.

[0067] The pulley includes a transmission part and a connection part. Along the axial direction of the pulley, the connection part is arranged on one side of the transmission part. On the end face of the transmission part facing away from the connection part, there are multiple fan blades 3b, and / or on the radial side surface of the transmission part along the pulley, there are multiple fan blades 3b. That is, the fan blades 3b can be arranged on the end face of the transmission part facing away from the connection part, can also be arranged on the radial side surface of the transmission part along the pulley, or there are fan blades 3b both on the end face of the transmission part facing away from the connection part and on the radial side surface of the transmission part along the pulley. The rotation of the pulley drives the rotation of the fan blades 3b. It should be noted that the connection part of the pulley refers to the area connected to the synchronous belt 4, and the transmission part of the pulley refers to the area not connected to the synchronous belt 4. Arranging multiple fan blades 3b on the transmission part of the pulley and arranging the multiple fan blades 3b around the axial direction of the pulley can avoid interference with the synchronous belt 4 during the rotation of the output end of the motor body 1 along with the fan blades 3b.

[0068] In some embodiments, the external connection method of the motor body 1 is not limited to belt drive through the pulley 3 and the synchronous belt 4. It can also be set that there is a gear drive between the motor body 1 and the speed reducer 5, or it can be set that the motor body 1 is directly connected to the speed reducer 5, and it can also be set that the motor body 1 is directly connected to the external component to be driven, etc.

[0069] In some embodiments, the transmission part includes a gear. The gear includes a toothed part and a mounting part. Along the axial direction of the gear, the mounting part is arranged on one side of the toothed part. On the end face of the mounting part facing away from the toothed part, there are multiple fan blades 3b, and / or on the radial side surface of the mounting part along the gear, there are multiple fan blades 3b. That is, the fan blades 3b can be arranged on the end face of the mounting part facing away from the toothed part, can also be arranged on the radial side surface of the mounting part along the gear, or there are fan blades 3b both on the end face of the mounting part facing away from the toothed part and on the radial side surface of the mounting part along the gear, so as to drive the rotation of the fan blades 3b through the rotation of the gear and increase the air flow speed in the accommodation cavity. It should be noted that the mounting part of the gear refers to the area other than the toothed part. Arranging multiple fan blades 3b on the mounting part of the gear and arranging the multiple fan blades 3b around the axial direction of the gear can avoid interference with the synchronous belt 4 during the rotation of the output end of the motor body 1 along with the fan blades 3b.

[0070] When the motor body 1 is working, the pulley or the gear drives the multiple fan blades 3b to rotate, which can increase the air flow speed in the accommodation cavity. Furthermore, by increasing the air flow speed in the accommodation cavity, the heat convection efficiency between the air in the cavity and the motor body 1, the inner surface of the housing 2 of the robot 10, and the heat conduction layer group 11 can be improved, and the heat in the accommodation cavity can be more efficiently dissipated to the outside of the housing 2, thereby improving the heat dissipation efficiency of the motor body 1 to the accommodation cavity and realizing the heat dissipation and cooling of the motor body 1.

[0071] As Figure 6 shown, the fan blades 3b on the transmission part 3 can be set in the shape of straight blades, such asFigure 7 As shown in Figure 7 , the fan blade 3b on the transmission member 3 can be set to other shapes such as curved blades. The fan blade 3b can be integrally processed with the transmission member 3, or can be embedded in the transmission member 3 by means of inlaying or the like.

[0072] In some embodiments, the heat conduction layer group 11 of the present application can be set as a single-layer flexible heat conduction medium layer to be applicable to the working condition where the distance between the motor body 1 and the housing 2 is very small. It is also possible to increase the heat conduction efficiency by applying a fluid heat conduction medium such as heat conduction silicone grease between the motor body 1 and the housing 2.

[0073] The present application sets the heat conduction layer group 11 between the housing 2 and the motor body 1, which has high heat dissipation efficiency and a simple installation method. At the same time, it has the advantages of simple structure, convenient operation, reducing the process complexity of installation and debugging, and being conducive to improving production efficiency. Combining the structures such as the first heat dissipation part 7b, the heat dissipation member 8, the second heat dissipation part 8a, the third heat dissipation part 2a provided in the present application, and the fan blade 3b on the belt pulley 3, etc., increases the heat convection area of the air in the accommodation cavity with the motor body 1 and the housing 2 of the robot 10, thereby improving the heat dissipation efficiency.

[0074] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the various technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0075] The above-described embodiments only represent several implementation manners of the present application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
