Description

Technical Field

[0001] The invention relates to the technical field of character action simulation, and in particular to a mechanical mechanism for imitating a character's head shaking action. Background Art

[0002] Character motion simulation refers to the process of capturing, analyzing and reproducing character motions through computer technology or other means. Character motion simulation has broad application prospects in many fields. For example, in the field of robotics, it can be used to control the head swing of humanoid robots; in the field of entertainment, it can be used for head swing performances of toy dolls, cartoon character models, etc.; in the field of virtual reality and augmented reality, it can be used to simulate the head movement of real people to enhance the user's immersion and interactive experience.

[0003] Currently, common human motion simulations are usually separate hand, leg or head motion simulations, but are unable to demonstrate the linkage effects of the hands and legs during head motions. For example, CN105171750B discloses a humanoid neck motion mechanism, which includes a base, a shaking head mechanism part, a nodding mechanism part and a swinging head mechanism part. Shaking the head is achieved by a motor driving large and small gear transmissions; nodding and tilting the head are achieved by a motor driving a disc clamp, which moves the head support disc to achieve nodding and tilting head movements; swinging the head is achieved by rotating two swing head motors, and swinging the middle rod and the lower swing rod through a swing head connecting rod. The application has a simple structure and enhances the anthropomorphic effect of the humanoid robot; the angles of head tilt and nodding are both 15°, the angles of shaking head left and right are between -45° and 45°, and the maximum angle of head shaking is 90°. It can complete the shaking and bobbing movements that a normal person can achieve, and the neck can complete movements such as Xinjiang dance. It looks less stiff during exercise and is more humanoid. However, the application only simulates head movements and does not simulate the corresponding movements of the limbs.

[0004] Chinese patent 202110816087X discloses a character action simulation device based on a big data platform, including a base, the upper part of the base is movably connected with a boxing mechanism, the boxing mechanism includes an elastic plate, the lower end of the elastic plate is fixedly connected with a gear rod extending into the inner cavity of the base, and the upper periphery of the gear rod is provided with an annular groove. The application applies a force to the elastic plate by the user to make the gear rod vertically displaced, and the striking mold rod will be controlled to be horizontally and longitudinally offset accordingly under the influence of different forces on the hinged rod and the telescopic magnetic block to imitate the character's confrontation action. During the cooperation, the U-shaped shielding plate is driven to block the telescopic magnetic block on the corresponding side or be between the telescopic magnetic blocks on both sides to adjust the longitudinal offset angle of the striking mold rod, thereby ensuring the authenticity of the simulation and enhancing the simulation effect, and effectively improving the flexibility of the equipment simulation. However, the application only simulates the movements of the hands in the full set of actions, and does not simulate the linkage movements of other parts during the hand movements.

[0005] Therefore, the present application hopes to provide a mechanical mechanism that imitates the head-shaking action of a person, which can simulate the coordinated action of the hands and legs during the head-shaking action, so as to present the coordinated movement effect between various parts of the human body, rather than simulating and reproducing a single part.

[0082] The cable of the motor 43 is attached to the back of the legs of the back plate 45, extends to the base 46 and passes through the large hole at the rear to connect to the power supply. This ensures that after power is turned on, only the movement of the character stickers can be seen from the front of the mechanism, and no rear mechanism components can be seen, thereby improving the visual experience.

[0083] The working principle of the present invention is as follows:

[0084] The motor shaft of the motor 43 is connected to the upper body gear 33 and drives the upper body gear 33 to rotate. The upper body gear 33 is slidably connected to the first slide groove 118 on the chest plate 11 through the first swing pin. The upper part of the chest plate 11 is connected to the transmission plate 31, the head connecting rod 41, and the back plate 45 through the pin passing through the first pin hole 111. When the upper body gear 33 rotates, the first swing pin will drive the chest plate 11 to swing back and forth around the pin in the first pin hole 111.

[0085] Since the diameter of the left elbow hole 115 of the chest plate 11 is larger than the diameter of the third pin shaft, and the diameter of the right elbow hole 114 is larger than the diameter of the fourth pin shaft, the elbows of the left upper arm connecting rod 12 and the right upper arm connecting rod 13 will have slight reciprocating vibrations, and at the same time, the left forearm connecting rod 14 and the right forearm connecting rod 15 will reciprocate slightly around the pin shafts in their sliding grooves.

[0086] Since the head gear 32 is meshed with the upper body gear 33 for transmission, the upper body gear 33 is meshed with the waist gear 34 for transmission, and the waist gear 34 is meshed with the abdomen gear 35 for transmission, when the upper body gear 33 rotates, the head gear 32, the waist gear 34 and the abdomen gear 35 all start to rotate under the gear meshing transmission.

[0087] The head gear 32 is connected to the eighth slide groove 48 of the head connecting rod 41 through a pin shaft, and can drive the head connecting rod 41 to swing back and forth around its pin shaft hole.

[0088] The waist gear 34 is connected to the seventh slide groove 47 of the waist connecting rod 42 through a pin shaft, and can drive the waist connecting rod 42 to swing back and forth around its pin shaft hole.

[0089] The abdominal gear 35 is connected to the fourth slide groove 214 of the abdominal plate 21 through a pin shaft, which can drive the abdominal plate 21 to swing back and forth around the center of the second pin shaft hole 211. During the swinging process, the abdominal plate 21 will drive the left leg connecting rod 23 and the right leg connecting rod 22 to move, and the left leg connecting rod 23 is connected to the transmission plate 31 through the eighth swing pin shaft slidingly connected in the sixth slide groove 25, and the left leg connecting rod 23 swings left and right around the eighth swing pin shaft, and the right leg connecting rod 22 is connected to the transmission plate 31 through the seventh swing pin shaft slidingly connected in the fifth slide groove 24, and the right leg connecting rod 22 swings left and right around the seventh swing pin shaft, so that it shows a reciprocating leg shaking action.

[0090] During the simulation process, the rotation angle of the upper body gear 33 can be adjusted to control the distance that the first swing pin moves in the first slide groove 118, and the swing angle of the chest plate 11 can be adjusted. Other parts will also be adjusted accordingly under the action of gear transmission to ensure the coordination of various body parts during head movement.

[0091] The present invention provides a mechanical mechanism for imitating a head-shaking action of a character, and the simulation of the head-shaking action of the human body and the simulation of the linkage effect of various body parts in the head-shaking process are achieved through the cooperation of an upper body mechanism, an abdomen mechanism, a transmission mechanism and a back plate mechanism, so as to present the coordinated movement effect of various parts of the head, upper body, arms, waist, abdomen and legs in the head-shaking process, and also by setting a sticker assembly and pasting stickers on various corresponding parts, a front-back three-dimensional sense is presented through the character stickers, and each sticker part is planned and designed, so that each part will not interfere with each other when moving at the same time; moreover, the motor cable is hidden at the back of the mechanism, and after power is turned on, no movement of any rear mechanism can be seen when observing from the front of the mechanism, and only the movement of the character stickers can be seen, which has a good visual perception effect.
