[0019] Example 1

[0020] See also Figure 1 The present embodiment provides a robot nodding movement structure, which includes a head 10, a neck connector 20 and a linkage component 30. The neck connector 20 is fixed to the robot trunk and movably connected to the head 10. The linkage component 30 is arranged in the head 10. The linkage component 30 is connected to the neck connector 20 and drives the head 10 to move. The linkage component 30 includes a fixing unit 31 and a driving unit 32 respectively arranged in the fixing unit 31 and a movement linkage unit 33 connected to the neck connector 20 and driven by the driving unit 32 to drive the head 10 to move.

A signal trigger switch is sleeved on the axis.

[0023] To summarize, since the neck bottom fixing part 1-332 is fixedly connected to the neck connecting part 20, when the driving unit 32 is started and the driving unit 32 performs forward rotation and reverse rotation alternately, it drives the driving gear 1-331 to rotate counterclockwise or clockwise, thereby making the first driven gear 1-330 meshing with the driving gear 1-331 transmit the transmission to each other, and the end face of the neck bottom fixing part 1-332 is formed with a convex tooth 1-333 meshing with one of the first driven gears 1-330 for transmission, thereby driving the head part 10 to move in the direction of the convex tooth 1-333 arranged on the circular connecting part to realize the nodding action.

By providing the microwave sensor and the sounder 50, when a person approaches a certain distance, the microwave sensor will sense it and feed back signals to the PCB board 40, and the PCB board 40 controls the driving unit 32 to drive the movement linkage unit 33 to realize nodding to the person, and the nodding can also be voice broadcast, such as hello, welcome, congratulations and good luck. It should be noted that the PCB board 40 is provided with a voice recognition module, and some simple voice dialogue programs will be input into the voice recognition module, so that the product has a simple voice dialogue function of a few sentences.

[0025] In this embodiment, the sound generator 50 adopts a speaker, the driving unit 32 includes a micro motor, the micro motor adopts a 280 micro motor, and the lithium battery 60 adopts a 18650 lithium battery 60; it should be noted that a charging interface passing through the head 10 is provided on the PCB board 40, and the lithium battery 60 can be charged by connecting the external connection through the charging interface.

[0027] The difference from Embodiment 1 is that in this embodiment, please refer to Figure 3 , the movement linkage unit 33 includes several second driven gears 2-330 that are meshed and driven within the fixed unit 31. One second driven gear 2-330 near one end of the drive unit 32 is provided with a first long shaft that passes through the fixed unit 31 at one end. A first driven large pulley 2-331 is connected to the first long shaft. The output end of the drive unit 32 passes through the fixed unit 31, and the output end of the drive unit 32 is provided with a first driving small pulley 2-332 that is connected to the first driven large pulley 2-331 through a belt. One second driven gear 2-330 far from the drive unit 32 is provided with a second long shaft that passes through the fixed unit 31 at both ends. Both ends of the second long shaft are rotatably connected to a U-shaped rotating frame 2-333 whose one end is connected to the neck connecting piece 20. By driving the belt by the drive unit 32, several second driven gears 2-330 are meshed and driven, thereby driving the U-shaped rotating frame 2-333 to swing, and pushing the head 10 to swing in one direction to achieve nodding of the head 10.

[0028] Embodiment 3

[0029] The differences from Embodiment 1 and Embodiment 2 are that in this embodiment, please refer to Figure 4 , the movement linkage unit 33 includes several third driven gears 3-330 that are meshed and driven within the fixed unit 31. One third driven gear 3-330 near one end of the drive unit 32 is provided with a third long shaft that passes through the fixed unit 31 at one end. A second driven large pulley 3-331 is connected to the third long shaft. The output end of the drive unit 32 passes through the fixed unit 31, and the output end of the drive unit 32 is provided with a second driving small pulley 3-332 that is connected to the second driven large pulley 3-331 through a belt. One third driven gear 3-330 far from the drive unit 32 is provided with a fourth long shaft that passes through the fixed unit 31 at one end. The fourth long shaft is provided with a swing arm 3-333, and one end of the swing arm 3-333 is hinged to a fixed arm 3-334 whose one end is connected to the neck connecting piece 20. By driving the belt by the drive unit 32, several third driven gears 3-330 are meshed and driven, thereby causing the fourth long shaft to drive the swing arm 3-333 to swing. Since one end of the swing arm 3-333 is hinged to the fixed arm 3-334, the head 10 can be pushed to swing to achieve nodding.

[0030] In summary, the utility model integrates the movement linkage unit 33 and the driving unit 32 in the fixing unit 31 so as to be installed in the head 10. The utility model has the advantages of simple production, simple and convenient assembly, good debugging, low cost, and is conducive to mass production.
