Description

Technical Field

[0001] This utility model relates to the field of toy technology, and more particularly to an electric drive mechanism for an animal toy. Background Technology

[0002] Existing animal toys generally fall into two categories: plush toys, which are stationary and suitable for young children; and moving toys, which use a drive mechanism to move their limbs and walk on the ground. Existing drive mechanisms can also perform multiple movements. For example, Chinese patent application CN213159372U discloses an electric doll that can stick out its tongue. A mechanism within the frame drives a rotating shaft, which in turn moves a transmission mechanism, causing the head to move. The transmission mechanism also moves a connecting plate, which in turn moves and resets the tongue assembly. When the doll walks on the ground, its head moves and it sticks out its tongue, enhancing its fun. However, the electric doll's movements are not varied enough; it cannot simultaneously perform a tail-wagging motion, resulting in low entertainment value. Furthermore, it cannot separately control the head and tongue or the legs for walking, indicating an unreasonable design and a poor user experience. Utility Model Content

When the drive gear of the drive gear group rotates in a reversing direction, one of the follower gears can move to engage with another follower gear, thereby driving the corresponding follower gear to rotate, and then driving the corresponding first action gear group or second action gear group to rotate and work. Ultimately, the first action gear group can drive the head and tongue assembly to move synchronously and the tail to swing simultaneously through the first and second rotating shafts, or the second action gear group can drive the legs to walk through the third rotating shaft. It can be seen that the electric drive mechanism of the animal toy provided by this utility model can achieve the purpose of separately controlling the synchronous movement of the head and tongue assembly and the walking movement by driving the drive gear to rotate in different directions. The player's operability is better, the game experience is better, and the tail swinging movement is added, which can improve the richness of the movement and increase the fun of the toy.

[0031] Please refer to Figures 1 to 9 This embodiment provides an electric drive mechanism for an animal toy, including a torso 100, a head 200, feet 300, and a tail 400. The head 200 is provided with a tongue assembly 500, and the torso 100 is provided with a drive assembly 600. The drive assembly 600 is used to drive the head 200, tongue assembly 500, tail 400, and feet 300 to make corresponding movements through a first linkage assembly 700, a second linkage assembly 800, and a third linkage assembly 900.

[0032] In this embodiment, the torso 100 includes an outer shell 110 and an inner shell 120 fixed within the outer shell 110. The outer shell 110 has a movably disposed head 200, feet 300, and tail 400 to simulate the shape of an animal. The inner shell 120 is used to fix and install the drive assembly 600, as well as the first linkage assembly 700, the second linkage assembly 800, and the third linkage assembly 900. It is understood that both the outer shell 110 and the inner shell 120 are constructed by splicing two shells together for ease of installation. In other embodiments of this invention, the torso 100 may consist of only a single-layer shell.

[0033] Understandably, the head 200 is also composed of two shells joined together. One side of the head 200 is rotatably connected to the inner shell 120 via a support rod 210, with both ends of the support rod rotatably connected to the head 200 and the inner shell 120 respectively. The other side of the head 200 opposite to the support rod 210 is rotatably connected to the outer shell 110 via the first link of the first linkage assembly 700, allowing the head 200 to swing relatively stably up and down on the torso 100 under the drive of the first link. It should be noted that two limiting blocks 220 are also provided on the head 200, respectively, located adjacent to the support rod 210 and the first link. The limiting blocks 220 are in contact with the support rod 210 and the first link to ensure that the amplitude of each up and down swing of the head 200 is basically consistent.

[0034] The foot 300 includes two front feet 310 and two rear feet 320 arranged opposite to each other, and the front feet 310 and rear feet 320 are controlled to swing synchronously via a third linkage component 900.

[0035] The tail section 400 includes a rotating rod 410, a first swing rod 420 and a second swing rod 430 fixed to both ends of the rotating rod 410. Both the first swing rod 420 and the second swing rod 430 are fixed to the rotating rod 410 in a manner intersecting the centerline of the rotating rod 410. The rotating rod 410 is rotatably connected to the inner wall of the outer casing 110 along its centerline. The first swing rod 420 is movably connected to the fifth link of the second linkage assembly 800 so that it pushes the rotating rod 410 to rotate. The second swing rod 430 swings on the outer casing 110 as the rotating rod 420 rotates, thus exhibiting a tail-wagging motion.

[0036] The tongue assembly 500 includes a first push rod 510, a second push rod 520, a tongue seat 530, and a connecting rod 540. The first push rod 510 is in the shape of an irregular triangular plate and has a first limiting hole 511 for movably connecting with the fourth link of the first linkage assembly 700. The first limiting hole 511 is an elongated hole. One end of the first push rod 510 is rotatably connected to the second link of the first linkage assembly 700, and the other end is rotatably connected to one end of the second push rod 520. The other end of the second push rod 520 is rotatably connected to one end of the tongue seat 530. The other end of the tongue seat 530 extends along the direction of tongue movement and has a sliding hole 531. A limiting rod horizontally positioned in the head 200 is movably connected within the sliding hole 531. One end of the connecting rod 540 is rotatably connected to the inner wall of the head 200, and the other end is rotatably connected to the middle of the tongue seat 530.

[0037] It should be noted that the first push rod 510 can be controlled to rotate relative to the second link during the linear movement of the fourth link, so as to drive the tongue seat 530 to move via the second push rod 520. Under the restriction of the sliding hole 531 and the limiting rod, the tongue seat 530 can be pushed by the second push rod 520 to extend and retract outward from the head 200. During this process, the tongue seat 530 can also rotate slightly relative to the limiting rod under the drive of the connecting rod 540, thereby making the tongue extension action of the tongue assembly 500 more flexible and improving the stability and reliability of the action execution.

[0038] In this embodiment, the drive assembly 600 includes a motor 610, a transmission group 620, a drive gear group 630, a first actuating gear group 640, and a second actuating gear group 650. The motor 610 is fixedly installed in the inner housing 120. The transmission group 620 includes a first rotating wheel 621, a second rotating wheel 622, and an output gear 623. The first rotating wheel 621 and the second rotating wheel 622 are rotatably mounted on the outer wall of the inner housing 120, and the output gear 623 is rotatably mounted within the inner housing 120. It is understood that the first rotating wheel 621 is fixed to the output shaft of the motor 610, the second rotating wheel 622 is connected to the first rotating wheel 621 via a transmission belt 624, and the output gear 623 is coaxially fixed with the second rotating wheel 622 and meshes with the drive gear of the drive gear group 630. The transmission group 620 and the drive gear form a reduction transmission system, used to increase torque and drive the drive gear to rotate at reduced speed. In other embodiments of this invention, the drive assembly 600 may omit the transmission group 620. In this case, the drive gear group 630 can be directly connected to the output shaft of the motor 610, allowing the drive gear group 630 to be driven to rotate by the motor 610. The transmission group 620 may employ other transmission structures, such as multiple gears meshing sequentially.

[0039] In this embodiment, the drive gear assembly 630 includes a driving gear 631, two follower gears 632, and a meshing gear 633. The driving gear 631 meshes with the output gear 623 to be driven to rotate, and is movably connected between the two follower gears 632. The two follower gears 632 are coaxially connected, and each has a first beveled end block 634 on its opposite side. Correspondingly, the driving gear 631 has second beveled end blocks 635 on its opposite sides. When the driving gear 631 rotates in the opposite direction, the second beveled end block 635, guided by the first beveled end block 634 it engages with, can move to engage with the other first beveled end block 634, thereby driving the corresponding follower gear 632 to rotate. In other words, when the driving gear 631 is controlled to rotate continuously in one direction, it can engage with one of the follower gears 632 and drive it to rotate. When the driving gear 631 is controlled to rotate continuously in the opposite direction, it can be guided to engage with the other follower gear 632 and drive it to rotate. Thus, the drive gear set 630 can cause different follower gears 632 to rotate after the motor 610 changes direction.

[0040] It is understood that the meshing gear 633 meshes with one of the follower gears 632, and the meshing gear 633 is rotatably mounted on the inner wall of the inner shell 120 via a T-shaft 636. An elastic element 637 connects the end of the T-shaft 636 and the meshing gear 633. This arrangement can offset some of the noise and vibration of the drive gear assembly 630, thereby reducing the noise and vibration generated by the drive gear assembly 630 and improving the smoothness of its operation. In other embodiments of this invention, the drive gear assembly 630 may not have a meshing gear 633, and the number of meshing gears 633 may be adjusted to two, each meshing with one of the two follower gears 632.

[0041] The first actuating gear group 640 and the second actuating gear group 650 are respectively engaged with a follower gear 632. The first actuating gear group 640 has a first rotating shaft 641 and a second rotating shaft 642. The first rotating shaft 641 drives the head 200 and tongue assembly 500 to move synchronously via a first linkage component 700. The second rotating shaft 642 drives the tail 400 to swing via a second linkage component 800. The second actuating gear group 650 has a third rotating shaft 651, which drives the feet 300 to walk via a third linkage component 900. In other words, the drive component 600 can independently drive the head 200 and tongue assembly 500 to move synchronously and accompany the tail 400 to swing, and the drive component 600 can also independently drive the feet 300 to walk, improving player operability and the gaming experience. It also adds the swinging motion of the tail 400, increasing the richness of the movements and enhancing the toy's fun.

[0042] In this embodiment, the first actuating gear assembly 640 includes a first gear 643, a second gear 644, and a third gear 645 that are sequentially meshed. The first gear 643 meshes with one of the follower gears 632, and its axial center is fixedly connected to the second rotating shaft 632. The axial center of the third gear 645 is fixedly connected to the first rotating shaft 641. It can be understood that the first actuating gear assembly 640 and the follower gear 632 form a reduction gear system, used to increase torque and drive the first rotating shaft 641 and the second rotating shaft 642 to rotate at reduced speed. The rotational speed of the first rotating shaft 641 is less than the rotational speed of the second rotating shaft 642, and the rotational speed of the second rotating shaft 642 is 1.8 times the rotational speed of the first rotating shaft 641, used to make the frequency of the toy's licking action (i.e., the effect presented by the synchronous movement of the head 200 and the tongue assembly 500) and tail wagging action closer to reality. In other embodiments of this utility model, the first actuating gear assembly 640 may be composed of other numbers of meshing gears, such as two or more. The rotational speed of the second shaft 642 can be 1.5 to 2 times that of the first shaft 641, for example, it can be adjusted to 1.5 times, 1.6 times, 1.7 times, 1.9 times or 2 times, etc.

[0043] In this embodiment, the second actuating gear set 650 includes a fourth gear 652 and a fifth gear 653 that are sequentially meshed. The fourth gear 652 is meshed with another follower gear 632, and the axial position of the fifth gear 653 is fixedly connected to the third rotating shaft 651. It can be understood that the second actuating gear set 650 and the follower gear 632 form a reduction gear system, used to increase torque and drive the third rotating shaft 651 to rotate at a reduced speed. In other embodiments of this invention, the second actuating gear set 650 may be composed of other numbers of meshing gears, such as one or more.

[0044] The first linkage assembly 700 includes a first eccentric wheel 710, a second eccentric wheel 720, a first connecting rod 730, a second connecting rod 740, a third connecting rod 750, and a fourth connecting rod 760. Both the first eccentric wheel 710 and the second eccentric wheel 720 are fixed to a first rotating shaft 641. In this embodiment, the first rotating shaft 641 and the second eccentric wheel 720 are integrally formed, and the first eccentric wheel 710 and the third gear 645 are circumferentially fixed to the first rotating shaft 641 via a concave-convex structure. The second eccentric wheel 720 includes a first wheel body 721 and a second wheel body 722 stacked and fixed. The centerline of the first wheel body 721 is parallel to the centerline of the first rotating shaft 641, and the centerlines of the second wheel body 722, the first eccentric wheel 710, and the first rotating shaft 641 coincide. That is, the first rotating shaft 641 is fixedly located at the eccentric position of the first wheel body 721. In other embodiments of this utility model, the first rotating shaft 641 can be separated from the second eccentric wheel 720 and configured as two separate components. In this case, the second eccentric wheel 720 can also be circumferentially fixed to the first rotating shaft 641 through a concave-convex structure.

[0045] The first connecting rod 730 is rotatably connected to the outer casing 110 at its middle part. One end of the first connecting rod 730 has a second limiting hole 731, which is an elongated hole and is movably fitted onto the eccentric block of the first eccentric wheel 710, allowing the first connecting rod 730 to swing left and right as the first eccentric wheel 710 rotates. Since the other end of the first connecting rod 730 is rotatably connected to the head 200, the first connecting rod 730 can drive the head 200 to swing up and down on the torso 100.

[0046] One end of the second connecting rod 740 is rotatably connected to the first wheel body 721, and the other end is rotatably connected to the first push rod 510. In this embodiment, the second connecting rod 740 is also provided with a first connecting block 741 between its two ends. One end of the third connecting rod 750 is rotatably connected to the eccentric block of the second wheel body 722, and the other end is rotatably connected to one end of the fourth connecting rod 760. The other end of the fourth connecting rod 760 is provided with a second connecting block 761, which is movably connected to the first limiting hole 511, so that the other end of the fourth connecting rod 760 can be movably connected to the first push rod 510. It is understood that the fourth link 760 has a third limiting hole 762 between its two ends. The third limiting hole 762 is an elongated hole and is movably sleeved on the first connecting block 741, so that the fourth link 760 can move up and down under the rotation of the third link 750, thereby pushing the first push rod 510 to swing left and right on the second link 740, and thus enabling the tongue seat 530 to achieve the extension and retraction of the tongue with the cooperation of other structural components. In other embodiments of this utility model, the first connecting block 741 may not be provided on the second link 740, and correspondingly, the third limiting hole 762 may not be provided on the fourth link 760.

[0047] It should be noted that since both the head 20 and the tongue assembly 500 are driven by the first linkage assembly 700, when the first rotating shaft 641 rotates, the first eccentric wheel 710 and the second eccentric wheel 720 rotate simultaneously in the same direction to synchronously drive the head 200 to swing up and down and the tongue assembly 500 to extend and retract, thereby presenting an imitation of an animal licking action.

[0048] The second linkage assembly 800 includes a third eccentric wheel 810 and a fifth link 820. The third eccentric wheel 810 is fixed to the second rotating shaft 642. One end of the fifth link 820 is rotatably connected to the eccentric block of the third eccentric wheel 810, while the other end of the fifth link 820 has a fourth limiting hole 821. The fourth limiting hole 821 is an elongated hole (or a frustum-shaped hole) and is movably fitted onto the first swing rod 420. It can be understood that the fifth link 820 can move up and down with the third eccentric wheel 810 during rotation, thereby pushing the first swing rod 420 to swing up and down along the rotating rod 410, causing the rotating rod 410 to rotate left and right, so that the second swing rod 430 can swing left and right on the body 100 to imitate the action of an animal wagging its tail.

[0049] The third linkage assembly 900 includes two fourth eccentric wheels 910, a sixth link 920, a pull rod 930, and a seventh link 940. The fourth eccentric wheel 910 is fixedly connected to the third rotating shaft 651. One end of the sixth link 920 is rotatably connected to the eccentric block of the fourth eccentric wheel 910 and fixedly connected to the front foot 310, allowing the sixth link 920 to swing the front foot 310 back and forth as the fourth eccentric wheel 910 rotates. The other end of the sixth link 920 has a fifth limiting hole 821, which is an elongated hole and movably fitted onto the inner shell 120, increasing the stability of the sixth link 920's movement. The two ends of the pull rod 930 are rotatably connected to one end of the sixth link 920 and one end of the seventh link 940, respectively. The other end of the seventh link 940 is rotatably connected to the inner shell 120 and fixedly connected to the rear foot 320. The lever 930 can swing back and forth with the sixth link 920, which in turn drives the seventh link 940 to swing left and right on the inner shell 120, so that the rear leg 320 can swing back and forth on the outer shell 110, cooperating with the front leg 310 to present the movement of simulating an animal walking.

[0050] For clarity, certain features described in individual embodiments of the present invention may be used in combination in a single embodiment. Furthermore, various features of the present invention described in individual embodiments may also be used individually or in any suitable form in sub-combinations.
