Description

Technical Field

[0001] This utility model relates to the field of robotics technology, specifically to a multi-expression robot head mechanical structure. Background Technology

[0002] Humanoid robots, also known as androids, are robots designed to mimic human appearance and behavior, especially those with similar physiques to humans. These robots can mimic a variety of human expressions by controlling the movement of their eyebrows, eyes, and mouth.

[0003] Currently, in order to achieve multiple facial expressions, some robot heads usually have a large number of servo motors inside. However, the servo motors generate heat when they are working. Furthermore, due to the large number of servo motors and the fact that various control mechanisms are packed inside the head, the robot head is prone to heat buildup, which can affect its lifespan. Utility Model Content

[0004] The purpose of this invention is to provide a multi-expression robot head mechanical structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-expression robot head mechanical structure, including a front shell and a heat dissipation assembly, wherein a rear shell is provided at the rear of the front shell, and a frame is provided at the bottom of the rear shell, the heat dissipation assembly is provided at the upper part of the frame, and the heat dissipation assembly includes a heat dissipation frame, a clearance opening, a connecting hole, a first filter screen and a second filter screen, the heat dissipation frame is provided at the upper part of the frame, the clearance opening is provided inside the heat dissipation frame, and a connecting hole is provided at the outer end of the middle part of the heat dissipation frame, the first filter screen is provided at the middle part of the rear shell, and the second filter screen is fixed at the middle part of the front shell.

[0006] Furthermore, the skeleton is n-shaped, and a mounting base is fixed to the middle of the inner side of the skeleton.

[0007] Furthermore, a reinforcing plate is fixed to one side of the mounting base, and the reinforcing plate is U-shaped.

[0008] Furthermore, the upper part of the frame is symmetrically provided with connecting plates, and the connecting plates are arc-shaped.

[0009] Furthermore, a nose bridge is mounted at the lower end of the frame, and the nose bridge is M-shaped.

[0010] Furthermore, a first connecting rib is provided on one side of the middle part of the skeleton, and a second connecting rib is connected to the lower end of the skeleton.

[0011] Furthermore, the end of the second connecting rib is connected to a ring, and the ring is annular and fixedly connected to the first connecting rib.

[0012] Furthermore, connecting seats are provided on both sides of the ring, and the connecting seats are triangular in shape.

[0013] This utility model provides a multi-expression robot head mechanical structure, which has the following beneficial effects:

[0014] 1. This utility model, through the setting of heat dissipation components, allows the outer shell of the cooling fan to be installed on the heat dissipation frame through the connection hole using fasteners. At this time, the clearance can avoid the air outlet of the fan, and the outer shell of the cooling fan will be tightly attached to the rear shell and aligned with the first filter screen. Thus, after the skin of the robot's face is covered, when the cooling fan is working, it will deliver the externally filtered air into the robot's head, so that the airflow flows out from the robot's eyes, nose, and mouth, taking away the heat generated by the control mechanism. Some air will also be discharged through the second filter screen, thereby avoiding heat accumulation caused by the robot's head having many servo motors due to multiple facial expressions, which is beneficial to extending the service life of the robot's head.

[0015] 2. This utility model can install and fix the front and rear ends of the eyebrow control mechanism through the setting of the mounting base and connecting plate, while the nose bracket can support and position the eye control mechanism, and the front and rear positions of the mouth control mechanism can be connected and installed through the middle of the nose bracket and the connecting base. This can separate the various mechanisms, make them distributed in an orderly manner, facilitate air circulation, and avoid the whole assembly being piled up together and affecting heat dissipation.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] like Figures 1 to 4 As shown, a multi-expression robot head mechanical structure includes a front shell 1 and a heat dissipation assembly 4. A rear shell 2 is provided at the rear of the front shell 1, and a frame 3 is mounted at the bottom of the rear shell 2. The heat dissipation assembly 4 is located on the upper part of the frame 3, and the heat dissipation assembly 4 includes a heat dissipation frame 401, a clearance opening 402, a connection hole 403, a first filter screen 404, and a second filter screen 405. The heat dissipation frame 401 is mounted on the upper part of the frame 3, and a clearance opening 402 is provided inside the heat dissipation frame 401. The middle part of the heat dissipation frame 401 is externally... The end has a connection hole 403, which can be used to install the housing of the cooling fan on the heat sink 401 through the connection hole 403 using fasteners. When the cooling fan is working, it will deliver filtered air from the outside to the inside, so that the airflow flows out from the robot's eyes, nose and mouth, and takes away the heat generated by the control mechanism. A first filter screen 404 is installed in the middle of the rear shell 2, and a second filter screen 405 is fixed in the middle of the front shell 1. The first filter screen 404 and the second filter screen 405 prevent dust from entering the robot's head.

[0023] like Figure 1 , Figure 3 and Figure 4 As shown, the skeleton 3 is n-shaped, and a mounting base 5 is fixed to the middle of the inner side of the skeleton 3. The rear part of the eyebrow control mechanism is positioned by the mounting base 5. A reinforcing plate 6 is fixed to one side of the mounting base 5, and the reinforcing plate 6 is U-shaped. The reinforcing plate 6 improves the stability of the skeleton 3. A connecting plate 7 is symmetrically arranged on the upper part of the skeleton 3, and the connecting plate 7 is arc-shaped. The front end of the eyebrow control mechanism is installed and fixed by the connecting plate 7. A nose bridge 8 is placed at the lower end of the skeleton 3, and the nose bridge 8 is M-shaped. The nose bridge 8 can support and position the eye control mechanism. A first connecting rib is provided on one side of the middle part of the skeleton 3. 9. The lower end of the frame 3 is connected to a second connecting rib 10, and the end of the second connecting rib 10 is connected to a support ring 11. The support ring 11 is annular and is fixedly connected to the first connecting rib 9. While improving the support strength, the first connecting rib 9 and the second connecting rib 10 have a large space, which facilitates airflow. The support ring 11 is provided with connecting seats 12 on both sides. The connecting seats 12 are triangular. The front and rear positions of the mouth control mechanism can be connected and installed through the middle of the nose bracket 8 and the connecting seats 12. The triangular connecting seats 12 can improve the support stability.

[0024] In summary, the mechanical structure of this multi-expression robot head, during use, firstly, uses fasteners to mount the cooling fan housing onto the heat sink 401 via the connecting hole 403. At this point, the clearance opening 402 can avoid obstructing the fan's air outlet. Next, the mounting base 5 and connecting plate 7 are used to install and fix the front and rear ends of the eyebrow control mechanism. The nose bracket 8 supports and positions the eye control mechanism, and the middle of the nose bracket 8 and connecting base 12 connect and install the front and rear positions of the mouth control mechanism. This allows for the separation and orderly distribution of the various mechanisms. To facilitate air circulation, after the front shell 1 and the rear shell 2 are fixed to the frame 3, the cooling fan housing will be tightly attached to the rear shell 2 and aligned with the first filter 404. Finally, after the skin is applied to the robot's face, the cooling fan will deliver the filtered air to the robot's head, allowing the airflow to flow out from the robot's eyes, nose, and mouth, carrying away the heat generated by the control mechanism. Some air will also be discharged through the second filter 405, thus preventing heat buildup caused by the numerous servo motors on the robot's head due to its many facial expressions, which helps extend the lifespan of the robot's head.
