It should also be understood that the term “and / or” as used herein refers to and includes any and all possible combinations of one or more of the associated listed items.

[0041] In the related art, the components such as motors and chips of electronic devices generate heat during use, and a fan needs to be arranged to dissipate heat of the heat generating components to ensure normal operation of the electronic device. Taking a robot as an example, with the acceleration of the bionics process such as vision and touch of the robot, the chip computing power requirement is gradually increased, thereby causing a significant heat dissipation problem. However, the fan with the expected heat dissipation capacity usually has a noise problem, which affects the user experience.

[0042] The present disclosure provides a heat dissipation assembly. Figure 1 is an exploded structural schematic diagram of a heat dissipation assembly in an exemplary embodiment of the present disclosure, as Figure 1 As shown, the heat dissipation assembly 1 includes a fan body 11, a damping support 12, and a fixing support 13. The damping support 12 is arranged between the fan body 11 and the fixing support 13, and the damping support 12 includes a main body structure 121 and at least one elastic cantilever 122 arranged on the main body structure 121. The main body structure 121 is assembled and cooperated with the fixing support 13, the main body structure 121 is provided with an air outlet passage 123, and the fan body 11 is assembled and cooperated with the elastic cantilever 122, so that the air outlet of the fan body 11 is aligned and cooperated with the air outlet passage 123 in the axial direction of the fan body 11.

[0043] In the above embodiment, the fixing support 13 can be used to fix and assemble the heat dissipation assembly 1 at a mounting position of a robot or other electronic device.

[0044] The heat dissipation assembly 1 includes the damping support 12 arranged between the fan body 11 and the fixing support 13. The main body structure 121 of the damping support 12 is assembled and cooperated with the fixing support 13, and the fan body 11 is assembled and cooperated with the elastic cantilever 122 of the damping support 12. The elastic potential energy generated by the elastic cantilever 122 relative to the main body structure 121 under stress is used to absorb the vibration of the fan body 11, thereby reducing the overall amplitude of the heat dissipation assembly 1. Without changing the size of the fan, the performance of the fan, and without increasing the external sound insulation structure, the noise problem of the heat dissipation assembly 1 is alleviated, which helps to reduce the space occupation and cost of the heat dissipation assembly 1. In addition, the demand for reducing the fan power to reduce the noise is also released, and the heat dissipation capacity of the heat dissipation assembly 1 is strengthened. Based on the above heat dissipation assembly 1, the fan body 11 can be selected to have a small impeller diameter, which is beneficial to save space and realize miniaturization of the whole machine.

[0045] It should be noted that the elastic suspension arm 122 refers to a structure capable of generating elastic potential energy relative to the main body structure 121 after being stressed. The structure parameters of the elastic suspension arm 122 can be matched and calculated through the vibration parameters of the fan body 11. The thickness, width, and length of the elastic suspension arm 122 are designed and calculated to obtain the expected stiffness. When the vibration of the fan body 11 is transmitted to the elastic suspension arm 122, the kinetic energy is absorbed by the elastic arm and converted into elastic potential energy, thereby reducing the system amplitude of the heat dissipation assembly 1. The elastic suspension arm 122 can have various setting schemes to achieve the installation of the fan body 11. For example:

[0046] In some embodiments, the elastic suspension arm 122 can be arranged at the inner edge of the main body structure 121 surrounding the air outlet channel 123 and extend towards the air outlet channel 123. The above scheme not only avoids the occupation of the elastic suspension arm 122 to the peripheral space of the main body structure 121, which helps to reduce the size of the damping support 12 in the plane perpendicular to the axial direction of the fan body 11, but also avoids the occupation of the elastic suspension arm 122 to the axial space, which helps to further reduce the size of the heat dissipation assembly 1 and the robot or electronic device using the heat dissipation assembly 1.

[0047] In some embodiments, the inner edge of the main body structure 121 can include a corner region, and the elastic suspension arm 122 is arranged at the corner region. The corner region provides sufficient extension space for the elastic suspension arm 122 and reduces the interference between the structure of the elastic suspension arm 122 and the fan body 11 at the arranged position. In addition, the support of the fan body 11 is realized from the corner region of the main body structure 121, which helps to improve the installation stability of the fan body 11.

[0048] In other embodiments, the elastic suspension arm 122 can also be arranged at the side of the main body structure 121 facing the fan body 11, and one end of the elastic suspension arm 122 is connected to the main body structure 121 to form a cantilever. The vibration of the fan body 11 can be converted into potential energy of the elastic suspension arm 122 by utilizing the cantilever feature.

[0049] In other embodiments, the elastic suspension arm 122 can also be arranged at the outer edge of the main body structure 121 or other positions, which is not limited in the present disclosure.

[0050] In some embodiments, as shown in Figure 2 , Figure 3 In the axial direction of the fan body 11, the projection of the air outlet channel 123 covers the projection of the fan body 11 to avoid the structural interference between the fan body 11 and the main body structure 121 affecting the buffering effect of the elastic suspension arm 122 on the fan body 11. In addition, the above structural arrangement helps to simplify the structure of the heat dissipation assembly 1 and improve the structural compactness of the heat dissipation assembly 1.

[0051] It should be noted that the elastic suspension arm 122 and the main body structure 121 can form an integrated structure to improve the processing convenience and structural reliability of the damping support 12. Alternatively, the elastic suspension arm 122 can be assembled on the main body structure 121 by bonding, clamping or the like to improve the assembly and replacement flexibility.

[0052] The material of the elastic suspension arm 122 and the main body structure 121 can be the same or different, so that the elastic suspension arm 122 can generate elastic potential energy relative to the main body structure 121 under stress. For example, the material of the elastic suspension arm 122 and the main body structure 121 can be plastic, which separates the fan body 11 and the fixed support 13 by plastic, and further absorbs the vibration generated by the fan body 11 by using the elastic performance of the plastic, which helps to further reduce the noise of the heat dissipation assembly 1. Alternatively, the elastic suspension arm 122 and the main body structure 121 can also be made of elastic materials such as rubber and silicone. Alternatively, the material of the main body structure 121 can be plastic, rubber or silicone, and the material of the elastic suspension arm 122 can be metal such as metal spring or spring, which can generate elastic potential energy. Alternatively, the material of the main body structure 121 can be metal or plastic, and the material of the elastic suspension arm 122 can be plastic, rubber or silicone.

[0053] In the above embodiment, as shown in Figure 3 The elastic suspension arm 122 can include a transition portion 1223 and a connecting portion 1222, and the connecting portion 1222 and the main body structure 121 are connected through the transition portion 1223. The width of the transition portion 1223 is narrower than that of the connecting portion 1222, and the structure of the connecting portion 1222 can be slightly larger than the cross-sectional size of the connecting member. For example, when the connecting member is a screw, the connecting portion 1222 can be a circular structure with a diameter slightly larger than that of the screw, and the circular structure is provided with a threaded hole. The transition portion 1223 can be a rectangular structure with a width smaller than the diameter of the circular structure, and the length of the transition portion 1223 is smaller than the width, so that the elastic suspension arm 122 is easy to deform under stress.

[0054] Alternatively, the elastic suspension arm 122 can also be a simple rectangle, circle, ellipse, irregular shape or the like to facilitate processing and manufacturing, and the present disclosure does not limit this.

[0055] The number of elastic suspension arms 122 can be set according to the specific installation requirements of the fan body 11, for example, four elastic suspension arms 122 can be provided for the damping support 12, and each elastic suspension arm 122 is arranged at the corner of the main body structure 121.

[0056] In some embodiments, as shown in Figures 1-3As shown, the elastic suspension arm 122 can be provided with a first assembly hole 1221, and the fan body 11 is provided with a second assembly hole 111, and the fan body 11 and the elastic suspension arm 122 are fixedly connected through a connecting piece passing through the first assembly hole 1221 and the second assembly hole 111, so as to improve the disassembly convenience of the fan body 11 through the above assembly mode. For example, the first assembly hole 1221 and the second assembly hole 111 can be threaded holes, and the connecting piece is a screw. The screw passing through the first assembly hole 1221 and the second assembly hole 111 realizes the fastening connection of the fan body 11 and the elastic suspension arm 122.

[0057] Alternatively, the above-mentioned fan body 11 can also be assembled and matched with the elastic suspension arm 122 through clamping, bonding, riveting and the like, and the present disclosure does not limit this. When the fan body 11 and the elastic suspension arm 122 adopt a detachable assembly scheme, it is convenient to replace the damping support 12 in combination with the specific use condition, so as to obtain an elastic suspension arm 122 with different stiffness to adapt to different specifications of the fan body 11.

[0058] In some embodiments, as shown in the drawings, Figures 1-3 As shown, the main body structure 121 is provided with a third assembly hole 1211, and the fixed support 13 is provided with a fourth assembly hole 132, and the main body structure 121 and the fixed support 13 are fixedly connected through a connecting piece passing through the third assembly hole 1211 and the fourth assembly hole 132, so as to improve the disassembly convenience of the damping support 12 through the above assembly mode. For example, the third assembly hole 1211 and the fourth assembly hole 132 can be threaded holes, and the connecting piece is a screw. The screw passing through the third assembly hole 1211 and the fourth assembly hole 132 realizes the fastening connection of the fan body 11 and the elastic suspension arm 122.

[0059] Alternatively, the above-mentioned main body structure 121 and the fixed support 13 can also be assembled and matched through clamping, bonding, riveting and the like, and the present disclosure does not limit this. When the main body structure 121 and the fixed support 13 adopt a detachable assembly scheme, it is convenient to replace the damping support 12 in combination with the specific use condition, so as to obtain an elastic suspension arm 122 with different stiffness to adapt to different specifications of the fan body 11.

[0060] In some embodiments, the heat dissipation assembly 1 can further include an elastic body 14, which is assembled between the elastic suspension arm 122 and the fan body 11 and abuts with the elastic suspension arm 122 and the fan body 11 respectively, so as to isolate the fan and the elastic suspension arm 122. The elastic body 14 is used to actively isolate vibration at the vibration source position, and the damping characteristics and elasticity of the elastic body 14 are used to absorb and convert vibration, which can reduce the system amplitude. The material of the above-mentioned elastic body 14 can be plastic, rubber, silicone and the like.

[0061] In some embodiments, as shown in the drawings, Figures 1-3In the illustrated embodiment, the elastic body 14 can be a rubber ring arranged between the elastic suspension arm 122 and the fan body 11, and a screw passes through the rubber ring to achieve elastic abutment of the elastic suspension arm 122 and the fan body 11.

[0062] In some embodiments, as Figures 4-6 As shown, the heat dissipation assembly 1 can further include an air guide support 15 assembled on a side of the fixed support 13 opposite to the damping support 12. In the axial direction of the fan body 11, the fixed support 13 is provided with an air outlet opening 131 arranged in position with the fan body 11, and the air guide region 154 of the air guide support 15 in position with the air outlet opening 131 is provided with at least one air guide plate 151 distributed around the axial direction, and the at least one air guide plate 151 is inclined towards the edge of the air guide support 15 relative to the air outlet direction. The air inlet end of the fan body 11 is the heat dissipation position of the heat generating device, and the air outlet is the external space of the whole machine. When the heat dissipation has no demand for the air pressure and air volume of the external space, the air pressure reduction can reduce the wind noise, and the inclination of the at least one air guide plate 151 towards the edge of the air guide support 15 relative to the air outlet direction can increase the air outlet area under the condition of the same air volume, thereby reducing the air speed, reducing the air pressure and further reducing the wind noise.

[0063] In the above embodiment, the air guide region 154 includes a central region, and the air guide plate 151 arranged in the central region is parallel to the air outlet direction, so as to ensure the air outlet direction of the central position through the air guide plate 151 parallel to the air outlet direction, and reduce the air outlet resistance.

[0064] In the above embodiment, among the air guide plates 151 distributed from the center of the air guide region 154 to the edge of the air guide region 154, the inclination angle of the air guide plate 151 relative to the air outlet direction gradually increases, so as to increase the air volume through the air guide plate 151 with gradually changing angle relative to the air outlet direction, and reduce the air outlet resistance.

[0065] For example Figure 6 As shown, Figure 6 The dashed arrows can represent the air outlet direction, one air guide plate 151 located in the central region is arranged parallel to the air outlet direction, and the inclination angle of the air guide plate 151 located in the periphery of the central region relative to the air outlet direction gradually increases from the center 152 to the edge 153, so as to reduce the air outlet resistance on the basis of increasing the air volume.

[0066] In other embodiments, the inclination angle of each air guide plate 151 relative to the air outlet direction can also be the same.

[0067] It should be noted that the air guide support 15 can be assembled on the side of the fixed support 13 opposite to the damping support 12 by screws, and can also be assembled and matched by clamping, bonding, riveting and the like, and the present disclosure does not limit this. When the main body structure 121 and the fixed support 13 adopt a detachable assembly scheme, the air guide support 15 can be replaced to obtain different air outlet areas according to specific use conditions. In addition, the fan main body 11 can be an axial fan.

[0068] The present disclosure further provides a robot, which comprises the heat dissipation assembly 1.

[0069] It should be noted that the robot can be one of a quadruped robot, a humanoid robot, a smart home robot, and a mechanical arm. The heat dissipation assembly 1 can be applied to the joints and main machine of the robot to dissipate heat from the motor, chip, battery and other heat generating components.

[0070] The present disclosure further provides an electronic device, which comprises the heat dissipation assembly 1.

[0071] It should be noted that the electronic device can be one of a mobile phone, a tablet computer, a computer, a vehicle-mounted device, a medical device, and a wearable device, and the present disclosure does not limit this. The heat dissipation assembly 1 can be used for heat dissipation of the mainboard and battery of the electronic device.

[0072] Since the heat dissipation assembly 1 comprises the damping support 12 arranged between the fan main body 11 and the fixed support 13, the main body structure 121 of the damping support 12 is assembled and matched with the fixed support 13, and the elastic suspension arm 122 of the fan main body 11 is assembled and matched with the damping support 12, the elastic potential energy generated by the elastic suspension arm 122 relative to the main body structure 121 under stress is used to absorb the vibration of the fan main body 11, the overall amplitude of the heat dissipation assembly 1 is reduced, the noise problem of the heat dissipation assembly 1 is reduced without changing the fan size, fan performance, and without increasing the external sound insulation structure, which helps to reduce the space occupation, cost, and strengthen the heat dissipation capacity of the heat dissipation assembly 1, and also improves the heat dissipation effect, thinness and use experience of the robot or electronic device using the heat dissipation assembly 1. Based on the heat dissipation assembly 1, the fan main body 11 can be selected to have a small impeller diameter, which is beneficial to save space and realize miniaturization of the whole machine.

[0073] The above merely describes the preferred embodiments of the present disclosure and is not intended to limit the present disclosure in any form. Although the present disclosure has been disclosed as the above preferred embodiments, it is not intended to limit the present disclosure, and any person skilled in the art can make some changes or modifications to the above disclosed technical contents without departing from the scope of the technical solutions of the present disclosure to obtain equivalent embodiments with equivalent changes.
