Novel content
The technical problem to be solved by the utility model is to provide a toy dog structure with a flexible neck.
The novel neck movement mechanical structure of the machine dog comprises a head, a body and a neck, wherein the neck comprises a transmission device and a rotating shaft, a positioning groove is formed in the bottom of the head, and the rotating shaft and the positioning groove are fixed with each other to drive the head to rotate; the transmission device comprises a fixed shell, a driving motor, a first transmission gear, a second transmission gear and a third transmission gear, wherein the first transmission gear is fixed with a bearing of the driving motor, the third transmission gear is fixed with the rotating shaft, and the second transmission gear is meshed with the first transmission gear and the third transmission gear respectively and is fixed in the fixed shell.
As a further description of the neck movement mechanism of the robot dog, the neck further comprises a protective cover, the upper and lower parts of the protective cover are respectively provided with a protective edge extending inwards, and the tail end of the protective edge is in contact with the side surface of the head.
As a further description of the neck movement mechanical structure of the robot dog, the head is provided with two connected rotating beads, and the bottoms of the two rotating beads are respectively connected with the two transmission blocks.
As a further description of the neck movement mechanical structure of the above robot dog, a reinforcing plate is fixed at the bottom of the head, and the rotating shaft and the bottom surface of the middle part of the reinforcing plate are fixed to each other to drive the reinforcing plate to rotate.
As a further description of the neck movement mechanical structure of the robot dog, the bottom of the rotating shaft is provided with a stop edge protruding outwards, the bottom of the third transmission gear is located above the stop edge, and the top of the third transmission gear is attached to the head.
This neotype beneficial effect is: the combination position of the head, the body and the neck 3 is realized by a transmission device, three layers of transmission gears are arranged in the transmission device, 2 transmission gears are directly combined with a stress end and a force application end, and the middle transmission gear is positioned by the transmission device, so that the degree of cooperation among the 3 transmission gears is higher; moreover, the upper side and the lower side of the gear are positioned, so that the gear can be effectively prevented from jumping up and down, and the stability of transmission is ensured. The protection dustcoat that sets up in the neck outside can guarantee that joint position is inside not damaged by the external world to and prevent that the outside from getting into the aqueous vapor, reach higher waterproof dustproof effect.

FIG. 1 is a cross-sectional view of the present invention;
fig. 2 is a partial enlarged structural view of the transmission device of the present invention.
Detailed Description
The novel mechanical neck movement structure of the robot dog is adopted, and referring to fig. 1-2, the mechanical neck movement structure of the robot dog comprises a head part 1, a body 2 and a neck part 3, wherein the neck part 3 comprises a transmission device and a rotating shaft 31, a positioning groove 11 is arranged at the bottom of the head part 1, and the rotating shaft 31 and the positioning groove 11 are mutually fixed to drive the head part 1 to rotate; the transmission device comprises a fixed shell 32, a driving motor 33, a first transmission gear 34, a second transmission gear 35 and a third transmission gear 36, wherein the first transmission gear 34 is fixed with a bearing of the driving motor 33, the third transmission gear is fixed with the rotating shaft 32, and the second transmission gear 35 is meshed with the first transmission gear 34 and the third transmission gear 36 respectively and is fixed in the fixed shell. This is novel to have utilized 3 drive gear, on corresponding to the axis of rotation of motor and neck respectively, combines through second drive gear 35 and 2 other gears, plays very accurate transmission effect between 3 persons, utilizes driving motor's accurate control, and the head rotates and can carry out small rotation action control as required.
As a further description of the movable structure of the neck 3 of the mechanical toy dog, the neck 3 further includes a protective cover 4, the upper and lower portions of the protective cover 4 are respectively provided with a protective edge 41 extending inwards, and the end of the protective edge contacts with the side surface of the head 1. The protective outer cover coats the joint position between the head 1 and the body 2 in multiple directions, so that the interior of the joint position can be prevented from being damaged or water vapor can enter the joint position, and meanwhile, the transmission device coated by the protective outer cover can assist the joint position to rotate more smoothly.
As a further description of the movable structure of the neck 3 of the mechanical toy dog, the head 1 is provided with two connected rotatable beads 12, and the bottoms of the two rotatable beads are respectively connected with two transmission blocks 13. When the eyes are controlled, the eyes can be controlled only by controlling the transmission block 13, and meanwhile, the eyeball of the eyes is connected to effectively realize synchronous action.
