[0029] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Embodiment 1

[0031] like Figure 1As shown in Figure 2, in this embodiment, a bionic motion structure of the head of a bionic animal doll is mainly disclosed, including a head shell 1, an ear component 2, a mouth component 3 and an eye component 4. The head shell 1 is provided with a window 5 for displaying the ear component 2, the mouth component 3 and the eye component 4. The head shell 1 is provided with a head bionic motion structure, and the bionic motion of the ear component 2, the mouth component 3 and the eye component 4 is driven by the head bionic motion structure and displayed through the window 5. For the window 5, in this embodiment, it can be a through hole or a notch; it should also be noted that in this embodiment, the head shell 1 is generally made of a hard material, and can also be made of a softer material. In order to ensure the feel of the head, granular fillers such as foam particles can be appropriately filled inside the head shell 1.

[0032] Further, such as Figure 2 , 3, 4, the head bionic motion structure includes: a shell 6, the outer surface of the shell 6 is symmetrically provided with a first plane 7 and a second plane 8, the shell 6 is provided with a drive assembly 9, and the first plane 7 and / or the second plane 8 are provided with a first transmission assembly 10 and a second transmission assembly 11 on at least one side; that is to say, the first plane 7 can be provided with one or both of the first transmission assembly 10 and the second transmission assembly 11, and the second plane 8 is the same. Of course, one of the first plane 7 and the second plane 8 can also be symmetrically arranged due to the structure being a mirror surface (the symmetry plane of the head shell 1). In this embodiment, only one situation is described, as follows; the shell 6 is used to isolate the drive assembly 9 and the first transmission assembly 10 and the second transmission assembly 11. The shell 6 is generally made of hard material, such as PVC; wherein the drive assembly 9 is composed of a motor, a gear set and a worm. Specifically, the motor includes a servo motor, a DC motor or a motor; the shaft of the worm is connected to the output shaft of the servo motor or the DC motor or the motor, and the worm is engaged with the gear set. Different gear ratios can be set according to the transmission requirements to achieve this. This is a conventional operation in this field and will not be explained one by one. In this embodiment, the driving assembly 9 is provided with two groups, one group drives the ear member 2 and the mouth member 3 to move through the first transmission assembly 10, and the other group drives the eye member 4 to move through the second transmission assembly 11. It should be noted that in this embodiment, the first transmission assembly 10 and the second transmission assembly 11 should be arranged in a flat manner to reduce the space occupied, and can be better used in dolls with smaller faces such as cats, and at the same time, it is convenient to fill the face with stuffing and enhance the feel of the doll.

[0033] Specifically, in order to achieve flattening, in this embodiment, Figure 2, 3, 4, 5, the first transmission assembly 10 includes: a wheel disc 12, a first driven rod 13, a second driven rod 15, and a frame 17; wherein the wheel disc 12, the frame 17 and the first driven rod 13 constitute a shaped closed cam mechanism; the wheel disc 12, the frame 17 and the second driven rod 15 constitute a shaped closed cam mechanism; further, the wheel disc 12 is a cylindrical structure and a wheel disc slide groove 36 is provided on the top surface, and the wheel disc slide groove 36 is constructed with a curved profile along the axial direction of the wheel disc 12. In other embodiments, the curved profile can be realized by a boss. In order to ensure the formation of a shaped closed cam mechanism, the curved profile of the side wall of the boss and the first driven rod 1 3 and the second follower rod 15 need to use a spring to maintain long-term contact to complete the "shape closure", or use magnetic adsorption to maintain long-term contact to complete the "shape closure". It should be emphasized that in the cam structure, whether it is a spring or magnetic adsorption to ensure long-term contact between the follower rod and the curved profile is common knowledge for those skilled in the art. For example, a compression spring (not shown in the figure) can be set between the frame and the first follower rod and the second follower rod; in this embodiment, the first follower rod 13 is arranged parallel to the top surface of the wheel disc 12 and a first slider 14 is fixed at its first end, and the first slider 14 slides upward in the wheel disc slot 36 The second end of the first driven rod 13 drives the ear component 2 to move. It should be noted that the rods involved in this embodiment are all long strips, and their cross-sections can be rectangular, circular or any polygonal. In addition, in this embodiment, the first end and the second end refer to the two ends of the long strip that are away from each other; the second driven rod 15 is arranged parallel to the top surface of the wheel disc 12 and a second slider 16 is fixedly provided at its first end, and the second slider 16 also slides in the wheel disc slot 36; the second end of the second driven rod 15 drives the mouth component 3 to move; the frame 17 is detachably fixedly arranged on the housing 6 to limit the first driven rod 13 and the second driven rod 1 5 makes linear reciprocating motion. It should also be noted that for the frame 17, its structure is not limited, but preferably, the frame 17 includes two parts, one part is a cover body that fits the wheel disc 12, and the other part is a limit structure fixedly arranged on the shell 6 (limiting the first driven rod 13 and the second driven rod 15 to make linear reciprocating motion); in addition, the wheel disc 12 is fully wrapped by the first part, the second part and the shell 6 of the frame 17, and only the first end of the first driven rod 13 and the second driven rod 15 is exposed, so that the influence of the filler can be avoided, and the volume can be further reduced, the space utilization rate can be improved, and the service life can be improved. The driving component 9 drives the rotating shaft of the wheel disc 12 to rotate through the gear set.

[0034] In addition, in the present embodiment, the first transmission assembly 10 drives the ear component 2 to swing through the first swinging mechanism. It should be noted that in other embodiments, the first driven rod 13 can be directly connected to the ear component 2 to realize the movement of the ear component 2. However, in the present embodiment, in order to improve the effectiveness of the simulation, a swinging method is adopted. Specifically, the first swinging mechanism is provided with two groups and is respectively arranged on the first plane 7 and the second plane 8. The two groups of first swinging mechanisms include an ear rod 18, a sleeve 19, and a moving rod 20 that are fixedly connected in sequence. The sleeve 19 is fixed to the housing 6 through the first rotating shaft 23. The moving rod A first slide groove 21 is provided on 20. It should be noted that, only one first slide groove 21 is required, that is, one moving rod 20 on the two groups of first swinging mechanisms only needs to be provided with a first slide groove 21; the second end of the first driven rod 13 is provided with a third slider 22, the third slider 22 is slidably set in the first slide groove 21 and drives the first swinging mechanism to swing around the first rotation axis 23 under the movement of the first driven rod 13; the ear component 2 is fixedly set on the ear rod 18; therefore, under the reciprocating linear motion of the first driven rod 13, the first swinging mechanism swings back and forth around the first rotation axis 23, thereby realizing the swing of the ear component 2.

[0035] Similarly, in this embodiment, the first transmission assembly 10 drives the mouth member 3 to swing through the second swing mechanism. In other embodiments, the second driven rod 15 can be directly connected to the mouth member 3 to achieve the movement of the mouth member 3. However, in this embodiment, in order to improve the effectiveness of the simulation, a swinging method is adopted. Specifically, the second mechanism includes a second rotating shaft 24, a fixing sleeve 25 for fixing the second rotating shaft 24 is provided on the housing 6, an external gear 27 is provided at the first end of the second rotating shaft 24, and a rack 26 is provided at the second end of the second driven rod 15. The rack 26 is meshed with the external gear 27 and drives the external gear 27 to rotate under the linear motion of the rack 26; the mouth member 3 is fixedly arranged on the second rotating shaft 24. Therefore, under the reciprocating linear motion of the second driven rod 15, the external gear 27 swings back and forth, thereby driving the mouth member 3 to swing, and performing bionic simulation.

[0036] In this embodiment, a driving rod 28 is also provided, which is arranged through the housing 6 and driven to rotate by the driving assembly 9; the driving assembly 9 drives the driving rod 28 to rotate in such a way that a gear is sleeved on the driving rod 28, and the driving assembly 9 drives it to rotate through the gear set. The second transmission mechanism is provided with two groups, which are respectively arranged on the first plane 7 and the second plane 8, and the two groups of second transmission mechanisms have the same structure and include: a driving disk 29, an upper eyelid structure 31 and a lower eyelid structure 32, a first driving rod 34 and a second driving rod 35; specifically, a driving shaft 30 is provided on the driving disk 29, and the driving shaft 30 and the driving rod 28 are not arranged on the same axis, and the driving rod 28 is located in the middle of the driving disk 29; generally speaking, the driving shaft 30 is relatively short, and its length does not exceed the outer edge of the frame 17; the first end of the upper eyelid structure 31 is sleeved with an eye rotation shaft 33, and the eye rotation shaft 33 is fixed to the housing 6, and the first end of the lower eyelid structure 32 is sleeved on the eye rotation shaft 33, and the eye component 4 is sleeved on the eye rotation shaft 33 and is located between the upper eyelid structure 31 and the lower eyelid structure 32. The eyelid structure 32; the first end of the first driving rod 34 is sleeved on the driving shaft 30, and the second end is sleeved on the upper eyelid structure 31; the first end of the second driving rod 35 is sleeved on the driving shaft 30, and the second end is sleeved on the lower eyelid structure 32; the connecting line of the driving shaft 30 and the driving rod 28, the connecting line of the two ends of the first driving rod 34, the connecting line between the first driving rod 34 and the eye rotation axis 33, and the connecting line between the eye rotation axis 33 and the driving rod 28, the four components form a four-bar structure, and the upper eyelid structure 31 is driven to swing through the four-bar mechanism; the lower eyelid structure 32 is similar, so under the rotation of the first driving disk 29, the first driving rod 34 and the second driving rod 35 drive the upper eyelid structure 31 and the lower eyelid structure 32 to achieve a blinking action.

[0037] In summary, in this embodiment, a group of drive components 9 arranged inside the shell 6 drives the first transmission component 10 to drive the ear component 2 and the mouth component 3 to move, and another group of drive components 9 drives the second transmission component 11 to drive the eye component 4 to move; the entire mechanism is integrated and miniaturized.

[0038] In addition, for the first transmission assembly 10, the wheel 12 drives the movement of the first driven rod 13 and the second driven rod 15 to drive the movement of the ears and the mouth, thereby simulating the movement of the animal; the adjustment of this movement process is achieved by changing the wheel slide 36, specifically, as Figure 6 As shown, the wheel chute 36 is an involute chute, a non-closed loop chute, with only a lift but no return stroke, and the return stroke is achieved by reversing the wheel 12; Figure 6As shown, the wheel slide 36 has two repose angles, which are 0°~143° and 233°~379° respectively, and the lift is 143°~233°; at this time, the wheel 12 rotates forward, and the lift angle is 90°; the wheel 12 rotates reversely, and the original lift angle becomes a return angle of 90°, and the angle between the first driven rod 13 and the second driven rod 15 is greater than 90° and less than 143°; Figure 6 As shown, 120° is used in this embodiment.

[0039] The whole movement process is: Figure 6 As shown, in the initial state, the first slider 14 is at 140°; the second slider 16 is at 260°, at this time, the wheel 12 is rotated counterclockwise, the first slider 14 enters the lift, driving the first driven rod 13 to move, the first driven rod 13 drives the ear component 2 to move, and the second slider 16 still moves within the far rest angle, so the mouth component 3 does not move; continue to rotate the wheel 12 counterclockwise, the first slider 14 enters the far rest angle, the second slider 16 still moves within the far rest angle, at this time, neither the ear component 2 nor the mouth component 3 moves. When the wheel 12 is rotated clockwise, the first slider 14 enters the return stroke (that is, the lift in counterclockwise rotation) from the far rest angle, driving the first driven rod 13 to move, and the first driven rod 13 drives the ear component 2 to move, and the second slider 16 still moves within the near and far stop angles, so the mouth component 3 does not move; continue to rotate the wheel 12 clockwise, the first slider 14 enters the near rest angle, so the ear component 2 does not move, the second slider 16 enters the return motion angle (lift in counterclockwise rotation) from the far rest angle and drives the second driven rod 15 to move, and the second driven rod 15 drives the mouth component 3 to move, and by repeatedly rotating the wheel 12 counterclockwise and clockwise, different movements of the ear component 2 and the mouth component 3 can be achieved.

[0040] Of course, you can also use the following methods, such as Figure 7 As shown, the wheel slide groove 36 is a closed-loop slide groove with a return stroke and a lift stroke, and a distal repose angle and a proximal repose angle are provided between the return stroke and the lift stroke; specifically, in the present embodiment, in counterclockwise rotation, the lift stroke is A (0°~90°), the distal repose angle is B (90°~120°), the return stroke is C (120°~210°), and the proximal repose angle is D (210°~360°); in the present embodiment, the angle between the first driven rod 13 and the second driven rod 15 is at any position between 90°~150°.

[0041] like Figure 7As shown, when the angle between the first driven rod 13 (not shown in the figure) and the second driven rod 15 (not shown in the figure) is 90°, the third slide groove 81 can be controlled to reciprocate 340° to achieve the separate movement of the mouth and the ear. Specifically, when the first slider 14 is at 0°, the second slider 16 is at 90°, the wheel slide groove 36 rotates 90° clockwise, the lift A becomes a return stroke, and the second slider 16 drives the second driven rod 15 (not shown in the figure) to move, thereby driving the mouth member 3 (not shown in the figure) to move. At this time, the first slider 14 (not shown in the figure) is at a near rest angle of D (210°~360°) slides smoothly, and does not drive the ear component 2 (not shown in the figure) to move, and the mouth component 3 (not shown in the figure) is moved independently as a whole; when the wheel slide 36 continues to rotate clockwise to 150°, the first slider 14 enters C (120°~210°), driving the first driven rod 15 (not shown in the figure) to move, thereby driving the ear component 2 (not shown in the figure). At this time, the second slider 14 slides smoothly within the near repose angle D (210°~360°), and does not drive the mouth component 3 (not shown in the figure) to move. The mouth and ears are controlled independently; when the wheel slide 36 is rotated counterclockwise, the above movement is reversed.

[0042] like Figure 8As shown, when the angle between the first driven rod 13 (not shown in the figure) and the second driven rod 15 (not shown in the figure) is 120°, the third slide 81 rotates 360° counterclockwise to drive the first driven rod 13 (not shown in the figure) and the second driven rod 15 (not shown in the figure). In the initial state before the rotation starts, the first slider 14 is at 0°, ready to enter the lift A (0°~90°); the second slider 16 is at 120°, ready to enter the return C (120°~210°); the wheel slide 36 is rotated counterclockwise, the first slider 14 enters the lift A (0°~90°), and the second slider 16 enters the return C (120°~210°), driving the first driven rod 13 (not shown in the figure) and the second driven rod 15 (not shown in the figure) to move simultaneously, thereby realizing the simultaneous movement of the mouth component 3 and the ear component 2; the wheel slide 36 rotates 90° counterclockwise After the wheel slot 36 rotates 120° counterclockwise, the second slider 16 is still in D, and the first slider 14 is ready to enter C. At this time, only the first slider 14 drives the ear component 2 to move; after the wheel slot 36 rotates 210° counterclockwise, the first slider 14 and the second slider 16 are both in D, and the mouth component 3 and the ear component 3 are both stationary; when the wheel slot 36 rotates counterclockwise to 240°, the second slider 16 is ready to enter A, and the first slider 14 is still in D. At this time, only the mouth component 3 moves; when it rotates to 330°, the second slider 16 is ready to enter B, and the first slider 14 is still in D. Thereafter, the mouth component 3 and the ear component 2 do not move until they move to the same position as the initial state, and the process is repeated.

[0043] It should also be noted that, in the present embodiment, the rotating shaft is provided as a round shaft in order to ensure rotation, but a square shaft may also be used by adding a bearing or a bearing sleeve between the square shaft and the component.

[0044] Embodiment 2

[0045] like Fig. 9 , as shown in 10 and 11, in this embodiment, the main structure is consistent with that in the first embodiment, the difference is that, in this embodiment, the top and bottom surfaces of the roulette wheel 12 are provided with roulette wheel grooves 36 (not shown in the figure), which are respectively the first roulette wheel groove 37 and the second roulette wheel groove 38, wherein the first roulette wheel groove 37 is linked to the first driven rod 13, and the second roulette wheel groove 38 is linked to the second driven rod 15, so that long-term rotation in one direction can be realized. Of course, the first roulette wheel groove 37 and the second roulette wheel groove 38 are both annular grooves.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
