Description

Technical Field

[0001] This utility model belongs to the field of robotics technology, specifically a robot head with a free-shaking mechanism after being touched. Background Technology

[0002] With the continuous development of technology, the development of robots has become increasingly mature. In existing technologies, the heads of most robots are fixed, meaning that their heads can only be rotated to face different directions through an electrically driven structure. However, for the purpose of biomimicry, the heads of robots in existing technologies cannot swing, which reduces the user experience. Utility Model Content

[0003] To address the problems mentioned in the background art, this utility model provides the following technical solution: a robot head with a free shaking mechanism after being touched, comprising a top assembly, a base assembly, a front face assembly, and a rear shell assembly. A central ball shaft passes through the central circular hole of the pitch rotating component and is fixed to the ball shaft fixing block on the back cover with screws. One end of the central ball shaft is spherical, so the spherical end of the central ball shaft can achieve arbitrary angle rotation within ±30° in three-dimensional space within the central circular hole of the pitch rotating component. The other end of the central ball shaft is hexagonal and is fixed to the top shaking component with screws.

[0004] Preferably, two metal washers are fixed at their respective positions on both ends of the pitch rotating component using screws.

[0005] Preferably, the drive module is fixed to the rotating base with drive module fasteners and screws, and the pitch rotating component with the central ball shaft installed is fixed to both sides of the rotating base with stepped cylindrical pins at both ends, and then fixed to the corresponding positions with screws and metal fixing plates.

[0006] Preferably, the long cylindrical pin passes through the rectangular slot of the pitch rotating component, and one end of the support arm is fixed to the cylindrical pin with screws, while the other end is also fixed to the output end of the drive module with screws.

[0007] Preferably, one end of the spring is installed at the relative position of the pitch rotating component and then fixed with screws by a metal pressure plate, while the other end of the spring is fixed to the boss of the head rocking component.

[0008] Preferably, the long rubber pad and the short rubber pad are fixed to the relative positions of the pitch rotating component with double-sided tape.

[0009] Preferably, the top part and the top rocker are fixed with screws, and the front face assembly and the rear shell assembly are respectively fixed with screws to the relative positions of the top rocker.

[0010] Preferably, the rotating base and the metal base are hinged together, and the metal base and the base assembly are fixed with screws.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention features a central support ball shaft that allows free rotation in three-dimensional space, and three-point support from two compression springs. When touched by hand, the robot's head can swing freely under the compression and elasticity of the springs, providing a better user experience.

[0013] Alternatively, the inertia of the drive module's rapid clockwise and counterclockwise rotation can be used to make the head rotate and sway, thus satisfying the user's experience. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Depend on Figure 1-4 This utility model discloses a robot head with a free-shaking mechanism after being touched, comprising the following components:

[0021] The robot head is composed of several parts, including a head assembly 101, a base assembly 201, a front face assembly 301, and a rear shell assembly 401, which together form a robot head with a free-shaking mechanism after being touched. A central ball shaft 101-3 passes through the central circular hole of the pitch rotating component 201-1 and is fixed to the ball shaft fixing block 201-2 with screws. One end of the central ball shaft 101-3 is spherical, allowing it to rotate at any angle within ±30° in three-dimensional space within the central circular hole of the pitch rotating component 201-1. The other end of the central ball shaft is hexagonal and is fixed to the head-shaking component 101-2 with screws.

[0022] Use screws to fix the two metal washers 201-3 to the relative positions of the two ends of the pitch rotating component 201-1;

[0023] The drive module 201-4 is fixed to the rotating base 201-6 with the drive module fixing part 201-5 and screws. The pitch rotating part 201-1 with the center ball shaft 101-3 installed is fixed to both sides of the rotating base 201-6 with the stepped cylindrical pins 201-7 at both ends. It is then fixed to the corresponding position of the rotating base 201-6 with screws and metal fixing pieces 201-8.

[0024] The long cylindrical pin passes through the rectangular slot 201-10 of the pitch rotating component 201-1. One end of the support arm 201-11 is fixed to the cylindrical pin 201-9 with screws, and the other end is also fixed to the output end of the drive module 201-4 with screws.

[0025] like Figure 2 As shown, after one end of the spring 201-12 is installed to the relative position of the pitch rotating component, it is fixed with screws by the metal pressure plate 201-13. The other end of the spring 201-12 is fixed to the boss of the head rocking component 101-2.

[0026] Long rubber pads 201-15 and short rubber pads 201-16 are fixed to their respective positions on the pitch-rotating component 201-1 using double-sided tape; the headpiece 101-1 and head-shaking component 101-2 are fixed with screws, and the front assembly 301 and rear shell assembly 401 are fixed to their respective positions on the head-shaking component 101-2 using screws. The rotating base 201-6 and the metal base 201-14 are hinged together, and the metal base 201-14 and the base assembly 201 are fixed with screws.

[0027] Since the front assembly 301, rear shell assembly 401, and head assembly 101-1 are all fixed to the head rocker 101-2 with screws, and the head rocker 101-2 and the pitch rotation assembly 201-1 are flexibly connected by a central ball shaft 101-3 and two springs 201-12, and the pitch rotation assembly 201-1 and the rotating base 201-6 are hinged by stepped cylindrical pins 201-7 at both ends; when the robot is not powered on, if you touch the front assembly 301 or the head assembly 101-1, due to gravity, the front spring 201-12 will be compressed, and the spherical end of the central ball shaft 101-3 can rotate at any angle within ±30° in three-dimensional space within the central circular hole of the pitch rotation assembly 201-1. Therefore, when you touch the robot's front assembly, the entire robot head will shake freely due to gravity until the shaking amplitude decreases and then stops.

[0028] Since the drive module 201-4 is fixed to the rotating base 201-6 with screws, and the output end of the drive module 201-4 and one end of the support arm 201-11 are fixed with screws, and the cylindrical pin 201-9 passes through the other end of the pitch rotating component 201-4 and the support arm 201-11 and is fixed with screws, when the drive module 201-4 rotates rapidly clockwise and counterclockwise, it drives the head-mounted rocking component 201-1 to rotate together. Due to the inertia generated by the rapid clockwise and counterclockwise rotation, the spring force generated by the compression of the entire robot head causes the entire robot head to rock freely until the rocking amplitude decreases and then stops.
