Problems solved by technology

[0003] For example, the Chinese patent with the notification number CN105818152B discloses a robot head motion system, which includes a vertical shaft, the upper part of the vertical shaft extends into the head, and the lower part of the vertical shaft is rotatably fixed on the torso, thereby realizing the level of the robot head. Rotation, there is a horizontal axis in the head, the head can rotate around the horizontal axis, a gear is rotatably connected to the column, and a rack meshing with it is set under the gear, and the rack is fixed to the head, so that through Driving the gear to rotate can drive the rack to move to complete the pitching action of the head. Although the transmission method of the gear and the rack can achieve good transmission, there will be a large gap between the gear and the rack. Finally, due to the existence of large gaps, it is easy to cause shaking and poor stability, which needs further improvement

Embodiment 2

[0049] Embodiment 2: a pitch mechanism, such as Figure 5 and Figure 6 As shown, it includes the movable body 17 and embodiment 1, wherein the movable body 17 is hollow inside and the structures such as the motor 5, the gear 2 and the rack 3 are all arranged in the movable body 17, so that the built-in concealment of the transmission structure is better, so that The external integrity of the pitch mechanism is better, and it is more beautiful; wherein the movable body 17 is fixed to the rack 3, the base 1 is provided with a penetrating portion 18 passing through the movable body 17, and the movable body 17 is provided with a sliding opening for the penetrating portion 18. The movable groove 19, so that when it is necessary to drive the movable body 17 to complete the pitching action, it is enough to turn on the motor 5 to drive the gear 2 to rotate, and the movable body 17 has the advantage of good stability.

Embodiment 3

[0050] Embodiment 3: a kind of intelligent robot, such as Figure 7 As shown, it includes a fuselage 20 and embodiment 2, wherein the movable body 17 is the robot head, and the bottom of the base 1 is horizontally connected to the fuselage 20, so that the robot head can not only rotate horizontally relative to the fuselage 20 , and at the same time, the movable body 17 can be pitched to switch between wake-up and sleep states.

Abstract

The invention discloses an intelligent robot, a pitching mechanism and a transmission structure thereof. The intelligent robot comprises a substrate, a rack and a gear. The gear is rotatably connectedto the substrate, the gear is engaged to the rack, the rack is slidably connected to the substrate, an elastic supporting part leaning against the rack is arranged on the substrate, the rack is arc-shaped, and the head of the robot is fixed to the rack, so that the gear rotates to drive the rack to move to pitch the robot head. In the transmission process of the gear and the rack, the elastic supporting part can be driven properly to shrink toward the substrate, so that the gear and the rack can transmit normally by means of an enough gap. After transmission, the elastic supporting part willrehabilitate under an elastic restoring force, so that the gap between the gear and the rack is reduced, and therefore, the stability of the gear and the rack after transmission is better, the condition of swinging is easily avoided, and the stability is better.

Description

technical field [0001] The invention relates to the field of mechanical transmission, more specifically, it relates to an intelligent robot, a pitching mechanism and a transmission structure thereof. Background technique [0002] Mechanical transmission is widely used in mechanical engineering. It mainly refers to the transmission of power and motion by mechanical means. The transmission mode of gear and rack is a common transmission structure, which is widely used in various mechanical products. [0003] For example, the Chinese patent with the notification number CN105818152B discloses a robot head motion system, which includes a vertical shaft, the upper part of which extends into the head, and the lower part of the vertical shaft is rotatably fixed on the torso, thereby realizing the level of the robot head. Rotation, a horizontal axis is set in the head, the head can rotate around the horizontal axis, a gear is rotatably connected to the column, and a rack meshing with ...
