Description

Technical Field

[0001] This invention relates to the field of electric bionic toys, and more particularly to a simple dual-mode driven electric bionic toy and its control method. Background Technology

[0002] Electric bionic toys are toys that mimic the shapes of various animals such as dinosaurs and lizards and can be driven. Because they can arouse children's interest in nature and the animal world, electric bionic toys are increasingly becoming an important choice among children's toys. In order to achieve a realistic effect, electric bionic toys must not only closely imitate the shape of various animals, but also have corresponding walking, mouth opening and closing, tail wagging and other motor functions.

[0003] Currently, to achieve the walking and mouth-opening / closing functions of electric bionic toys, one possible approach is to use two sets of drive components, each containing a motor. One set drives the mouth's opening and closing, while the other controls the leg movements, thus enabling multiple actions. However, this approach is not only structurally complex and costly, but also limited in its ability to drive complex movements of the bionic components. Another approach is to use a single-motor drive component, with a linked transmission mechanism to synchronously control the leg movements and mouth opening and closing. The drawback of this approach is that it can only control the synchronized movements of the legs and mouth, reducing user engagement and making the simulated movements appear stiff and unnatural.

[0004] It is evident that existing technologies for imitating animal movements suffer from problems such as complex structure, high cost, poor controllability, and rigid movement simulation. Summary of the Invention

[0005] In view of this, the main objective of the present invention is to provide a simple dual-mode driven electric bionic toy and its control method, which can realize the movement drive of the head and legs based on a single drive mechanism, thereby simplifying the structure, reducing costs, and improving the toy's controllability and realism.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] In a first aspect, the present invention provides an electric simulation toy, including a head, a torso, legs, and a first drive mechanism, wherein the head and legs are movably connected to the torso, and the first drive mechanism includes a first motor, a first gear set, and a second gear set.

[0008] The first gear set is used to output rotational power to the legs to drive leg movement, and the second gear set is used to output rotational power to the head to drive head movement.

[0009] The first gear set is provided with at least a first input gear, and the second gear set is provided with at least a second input gear;

[0010] The first input gear is rotatably mounted on one side of the output gear of the first motor, so that the first input gear meshes with the output gear of the first motor when the first motor rotates in a first direction, and moves away from the output gear of the first motor when the first motor rotates in the opposite second direction.

[0011] The second input gear is rotatably mounted on the other side of the output gear of the first motor, so that the second input gear meshes with the output gear of the first motor when the first motor rotates in the second direction, and moves away from the output gear of the first motor when the first motor rotates in the first direction.

[0012] Optionally, the first drive mechanism further includes a linkage rod, with the shafts of the first input gear and the second input gear respectively limited and connected to both ends of the linkage rod, so that when the first motor rotates in the first direction, the meshing of the output gear of the first motor with the first input gear will simultaneously push the second input gear away from the output gear of the first motor, and when the first motor rotates in the second direction, the meshing of the output gear of the first motor with the second input gear will simultaneously push the first input gear away from the output gear of the first motor.

[0013] Optionally, the first drive mechanism further includes a gearbox, the gearbox being provided with a first guide groove and a second guide groove respectively located on both sides of the first motor, the first input gear being rotatably mounted in the first guide groove, and the second input gear being rotatably mounted in the second guide groove, the first guide groove being an arc centered on the stage gear following the first input gear, and the second guide groove being an arc centered on the stage gear following the second input gear.

[0014] Optionally, the first drive mechanism further includes a swing assembly, and the legs are provided in two and respectively hinged to both sides of the body. The first gear set is used to provide rotational power to the swing assembly, and the swing assembly drives the two legs to swing around the hinge point.

[0015] Optionally, the two eccentric shafts of the swing assembly and the two sliders are coaxially connected to the two eccentric shafts on both sides of the output gear of the first speed gear set. The eccentric shafts on both sides have different eccentric angles relative to the axial direction. The two sliders are respectively slidably positioned on the body. Each eccentric shaft is driven and connected to each slider in a one-to-one manner to limit the slider's sliding. Each slider is provided with a push rod, and each push rod extends into the leg at the eccentric body-leg hinge to drive the leg to swing around the body-leg hinge.

[0016] Optionally, the first drive mechanism further includes a tensioning assembly, and the second gear set is used to provide rotational power to the tensioning assembly, which is used to drive the upper jaw and lower jaw to move relative to each other.

[0017] Optionally, the second gear set is provided with a one-way transmission component, and the opening and closing assembly is provided with a reset component, so that when the first motor rotates, the first gear set can be transmitted to the opening and closing assembly via the one-way transmission component, and when the reset component drives the opening and closing assembly to reset, the one-way transmission component will idle.

[0018] Optionally, each leg is hinged to a palm on its lower side, and a walking wheel is provided on the bottom side of the palm. A second drive mechanism is provided inside the palm, and the second drive mechanism is driven and connected to the walking wheel.

[0019] In a second aspect, the present invention provides a control method for the aforementioned electric simulation toy, the control method comprising the steps of:

[0020] In response to a motion command on the legs of an electric bionic toy, the first motor is controlled to rotate in a first direction;

[0021] In response to a motion command on the head of an electric bionic toy, the first motor is controlled to rotate in the second direction.

[0022] In a third aspect, the present invention provides a driving device, including a first motor, a first gear set, and a second gear set, wherein the first gear set is provided with at least a first input gear, and the second gear set is provided with at least a second input gear.

[0023] The first input gear is rotatably disposed on one side of the output gear of the first motor, so that the first input gear meshes with the output gear of the first motor when the first motor rotates in a first direction, and moves away from the output gear of the first motor when the first motor rotates in the opposite second direction;

[0024] The second input gear is rotatably disposed on the other side of the output gear of the first motor, so that the second input gear meshes with the output gear of the first motor when the first motor rotates in a second direction, and moves away from the output gear of the first motor when the first motor rotates in a first direction.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] This invention, by incorporating a first motor, a first gear set, and a second gear set in the torso, allows the first motor to rotate in a first direction, driving the first gear set while the second gear set remains inactive, thus driving the legs to swing while the head remains stationary. Conversely, when the first motor rotates in a second direction, it drives the second gear set while the first gear set remains inactive, driving the head to open and close its mouth. This allows multiple toy simulation actions to be performed independently using a single drive mechanism, achieving a simplified structure and reduced costs while improving the toy's controllability and realism.

Detailed Implementation

[0037] To better illustrate the objectives, technical solutions, and advantages of the present invention, the specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0038] refer to Figures 1 to 8 This is an electric simulation toy according to an embodiment of the present invention. For example... Figure 1 As shown, the main body of this electric bionic toy consists of a head 10, a body 20, legs 30, palms 40, and a tail 50. The head 10, body 20, legs 30, palms 40, and tail 50 are all hollow shells mimicking the appearance of a dinosaur. The head 10 is located at the front of the body 20 and includes an upper jaw 11 and a lower jaw 12 that can open and close relative to each other. There are two legs 30, hinged to the left and right sides of the body 20. Each leg 30 has a palm 40 on its underside. The tail 50 is located at the rear of the body 20. Therefore, moving the upper jaw 11 and / or the lower jaw 12 can mimic the opening and closing of a mouth. Simultaneously, moving the two legs 30 around their hinges can mimic bipedal walking.

[0039] To achieve the purpose of the invention, the electric simulation toy also includes a first drive mechanism 60. The first drive mechanism 60 is disposed within the body portion 20. The first drive mechanism 60 includes a first motor 61, a first gear set 62, a second gear set 63, and a gearbox 66. The first gear set 62 is used to output rotational power to the legs 30 to drive their movement. The second gear set 63 is used to output rotational power to the head 10 to drive its movement.

[0040] refer to Figure 2 and Figure 3 In detail, the gearbox 66 is provided with a first guide groove 661 and a second guide groove 662 located on both sides of the first motor 61. The first transmission gear set 62 consists of a first input gear 621, a first output gear 622, and several other gears. The first input gear 621 is rotatably mounted on the first guide groove 661 of the gearbox 66. The first guide groove 661 is an arc shape with the rear gear of the first input gear 621 as its center. When the shaft of the first input gear 621 swings to the lower side of the first guide groove 661, the first input gear 621 meshes with the output gear of the first motor 61. When the shaft of the first input gear 621 swings to the upper side of the first guide groove 661, the first input gear 621 disengages from the output gear of the first motor 61. It can be seen that the first input gear 621 is rotatably mounted on the rear side of the output gear of the first motor 61.

[0041] Similarly, the second gear set 63 consists of a second input gear 631, a second output gear 632, and several other gears. The second input gear 631 is rotatably mounted on a second guide groove 662 of the gearbox 66. The second guide groove 662 is an arc shaped with the subsequent gear of the second input gear 631 as its center. When the shaft of the second input gear 631 swings to the lower side of the second guide groove 662, the second input gear 631 meshes with the output gear of the first motor 61. When the shaft of the second input gear 631 swings to the upper side of the second guide groove 662, the second input gear 631 disengages from the output gear of the first motor 61. Therefore, the second input gear 631 is rotatably mounted in front of the output gear of the first motor 61.

[0042] refer to Figure 2 and Figure 3 In detail, the pivot of the first input gear 621 is limited and connected to the rear side of the linkage rod 64, and the pivot of the second input gear 631 is limited and connected to the front side of the linkage rod 64. It can be understood that the first input gear 621 and the second input gear 631, under the influence of gravity, have a tendency to slide correspondingly to the lower side of the first guide groove 661 and the second guide groove 662. Figure 2As shown, when the first motor 61 rotates clockwise, the first input gear 621 can move to the lower side of the first guide groove 661 and mesh with the output gear of the first motor 61, driving the first input gear 621 to rotate counterclockwise, and further maintaining the meshing between the first input gear 621 and the output gear of the first motor 61. During this process, the linkage rod 64 will swing clockwise, driving the second input gear 631 to remain disengaged from the output gear of the first motor 61. Similarly, as... Figure 3 As shown, when the first motor 61 rotates counterclockwise, the second input gear 631 can move to the lower side of the second guide groove 662 and mesh with the output gear of the first motor 61, driving the second input gear 631 to rotate clockwise, and further keeping the second input gear 631 and the output gear of the first motor 61 meshed. During this process, the linkage rod 64 will swing counterclockwise, causing the first input gear 621 to remain separated from the output gear of the first motor 61, and preventing it from falling to the position where it meshes with the output gear of the first motor 61.

[0043] Therefore, when the first motor 61 rotates in the first direction, the first input gear 621 remains engaged with the first motor 61, while the first motor 61 is disengaged from the second input gear 631. The first motor 61 drives the leg 30 to swing only through the first gear set 62, while the second gear set 63 does not rotate or perform mouth opening and closing movements. Similarly, when the first motor 61 rotates in the opposite second direction, the second input gear 631 remains engaged with the first motor 61, while the first motor 61 is disengaged from the first input gear 621. The first motor 61 drives the upper jaw 11 and lower jaw 12 to perform mouth opening and closing movements only through the second gear set 63, while the first gear set 62 does not rotate or perform leg swinging movements. Therefore, based on the first motor 61, the first gear set 62 and the second gear set 63, this embodiment can drive the leg 30 to make a swinging motion or drive the head 10 to make a mouth opening and closing motion, thereby increasing the fun of operation for users in a simple structure.

[0044] Continue to refer to Figures 1 to 3According to an embodiment of the present invention, there is also a control method for the above-mentioned electric bionic toy. The electric bionic toy of this embodiment is a remotely controlled toy. A battery compartment 25 and a control circuit board 24 are provided inside the body 20. The battery compartment 25 can be fitted with batteries to provide power. The control circuit board 24 is used to control the operation of the first drive mechanism 60. The user can send commands to the control circuit board 24 through a remote control that matches the control circuit board 24. The control method of this embodiment includes the following steps: (1) In response to a received command for the leg 30 to swing, the control circuit board 24 controls the first motor 61 to rotate in a first direction. (2) In response to a received command for the mouth to open and close, the control circuit board 24 controls the first motor 61 to rotate in a second direction.

[0045] For ease of understanding, in this embodiment, in step (1), after receiving the leg 30 swinging action command, the control circuit board 24 controls the first motor 61 to rotate clockwise. The first motor 61 meshes with the first input gear 621, and the first gear set 62 operates, pushing the legs 30 on both sides to swing. In step (2), after receiving the mouth opening and closing action command, the control circuit board 24 controls the first motor 61 to rotate counterclockwise. The first motor 61 meshes with the second input gear 631, and the second gear set 63 operates, pushing the upper jaw 11 and lower jaw 12 to perform mouth opening and closing actions.

[0046] Therefore, it can be seen that the control method of the electric bionic toy in this embodiment allows the leg 30 to swing and the mouth to open and close independently, which is interesting to operate.

[0047] refer to Figure 1 and Figure 5 To improve the simulation effect of the swinging motion, in this embodiment, each leg 30 is specifically hinged to a palm 40 on its lower side, and each palm 40 is provided with two walking wheels 41. The two walking wheels 41 are parallel to each other axially, with one walking wheel 41 located at the front along the direction of travel and the other walking wheel 41 located at the rear along the direction of travel. At least four auxiliary wheels 42 are also provided on the bottom side of the palm 40, one located in front of the front walking wheel 41, one located behind the rear walking wheel 41, and the remaining two located on the left and right sides of the direction of travel, respectively. A second drive mechanism 90 is provided in each palm 40. The second drive mechanism 90 is driven and connected to the walking wheels 41. The second drive mechanism 90 includes a second motor 91 and a third gear set 92. The second motor 91 is driven and connected to the front side of the third gear set 92, and the rear side of the third gear set 92 is driven and connected to both the front and rear walking wheels 41. Thus, as the left and right legs 30 swing, at least one of the two palms 40 can contact the walking surface and drive the toy to move, while the auxiliary wheel 42 will further provide rolling contact support for the toy's movement.

[0048] refer to Figure 4 and Figure 5 To improve the simulation effect of the swinging motion, this embodiment specifically includes a swing assembly 70 in the first drive mechanism 60. The swing assembly 70 includes two eccentric shaft wheels 71 and two sliders 72. The two sides of the first output gear 622 are coaxially connected to the two eccentric shaft wheels 71. The eccentric angle difference between the two eccentric shaft wheels 71 is 180 degrees. Each slider 72 is laterally linearly slidable on the body part 20 through a transverse groove. Each slider 72 converts the eccentric motion of the eccentric shaft wheel 71 into linear reciprocating motion through a longitudinal groove. Each slider 72 is provided with a push rod 73, which extends into the leg part 30 through the eccentric first hinge 43, so as to drive the leg part 30 to swing around the first hinge 43.

[0049] It is worth noting that the push rods 73 on both sides can move in a lateral reciprocating linear motion, thereby pushing the leg 30 to swing back and forth around the hinge. For example... Figure 5 As shown, the left push rod 73 moves to the rear, causing the left leg 30 to swing forward, while the right push rod 73 moves to the rear, causing the right leg 30 to swing backward. Due to the opposite phase, the angle of the left leg 30 swinging forward and the angle of the right leg 30 swinging backward are approximately the same. Under the action of the support link 31, the left palm 40 is pushed, increasing the angle between the left palm 40 and the leg 30. Similarly, the angle between the right palm 40 and the leg 30 decreases, so that the bottom plates of the left and right palms 40 are approximately on the same plane, thus ensuring that the walking wheel 41 contacts the ground. Figure 5 As shown, if the left push rod 73 moves from the rear to the middle, it will cause the left leg 30 to move from front to back to the middle. Simultaneously, the right push rod 73 moves from the front to the middle, causing the right leg 30 to move from back to front to the middle. At this time, the distance between both palms 40 and the torso 20 is the same, and both palms 40 can remain on the same plane. Figure 5 As shown, if the left push rod 73 moves from the middle to the front, it will cause the left leg 30 to move backward from the middle. At the same time, the right push rod 73 moves from the middle to the rear, causing the right leg 30 to move forward from the middle. At this time, the distance between the palms 40 on both sides and the torso 20 is the same, and the palms 40 on both sides can remain on the same plane.

[0050] refer to Figure 5Each of the two palm portions 40 has a first hinge 43 and a second hinge 44. A support link 31 is provided inside the leg portion 30. On either side, the upper side of the leg portion 30 is hinged to the body portion 20, and the lower side of the leg portion 30 is hinged to the first hinge 43 of the palm portion 40. The upper end of the support link 31 passes through the leg portion 30 and is hinged to the body portion 20, while the lower end of the support link 31 is hinged to the first hinge 43 of the palm portion 40. In other words, the palm portion 40 and the body portion 20 form a quadrilateral multi-link structure through the cooperation of the leg portion 30 and the support link 31, so that the palm portion 40 can maintain a relatively horizontal state as the leg portion 30 swings. With the symmetrical axis of the left and right legs 30, when the two legs 30 swing forward and backward at the same angle, the two palm portions 40 can be kept approximately on the same support plane.

[0051] It can be seen that by setting the support link 31 and the phase setting of the push rods 73 on both sides, the two legs 30 can make alternating swinging movements, while the two palms 40 can also provide stable omnidirectional motion capability.

[0052] refer to Figures 6 to 9 To improve the simulation effect of the swinging motion, in this embodiment, the first drive mechanism 60 specifically includes a tensioning assembly 80, and a second gear set 63 for providing rotational power to the tensioning assembly 80. The tensioning assembly 80 is used to drive the upper jaw 11 and lower jaw 12 to perform relative tensioning and opening movements. The second gear set 63 is provided with a one-way transmission member 65, and the tensioning assembly 80 is provided with a reset member, so that when the first motor 61 rotates, the first gear set 62 can be transmitted to the tensioning assembly 80 via the one-way transmission member 65, and when the reset member drives the tensioning assembly 80 to perform a reset movement, the one-way transmission member 65 will idle.

[0053] In detail, such as Figure 6 and Figure 7As shown, the jaw-opening assembly 80 includes a maxillary link 81, a mandibular link 82, an intermediate link 83, a transmission rocker arm 84, and a return torsion spring 85. The return torsion spring 85 is a return element. Specifically, the maxillary portion 11 and the mandibular portion 12 are hinged to the front end of the body portion 20, rotatably about the same axis. The maxillary portion 11 has a maxillary rocker arm 13 extending rearward from the hinge point, and the mandibular portion 12 has a mandibular rocker arm 14 extending rearward from the hinge point. The front end of the maxillary link 81 is hinged to the maxillary rocker arm 13, and the front end of the mandibular link 82 is hinged to the mandibular rocker arm 14. The rear end of the maxillary link 81 is hinged to the rear end of the mandibular link 82 and is hinged to the front end of the intermediate link 83. It is understandable that when the rear ends of the maxillary rocker arm 13 and the mandibular rocker arm 14 approach each other, they will cause the maxillary portion 11 and the mandibular portion 12 on the opposite side of the hinge to open. Therefore, by pulling the rear ends of the maxillary connecting rod 81 and the mandibular connecting rod 82 backward, the maxillary portion 11 and the mandibular portion 12 can achieve the opening movement. Similarly, when the rear ends of the maxillary rocker arm 13 and the mandibular rocker arm 14 move away from each other, the maxillary portion 11 and the mandibular portion 12 will perform a closing movement. Therefore, the rear ends of the maxillary connecting rod 81 and the mandibular connecting rod 82 can be pushed forward to achieve the closing movement. The rear end of the intermediate connecting rod 83 and the front end of the transmission rocker arm 84 are hinged to the rear end of the intermediate connecting rod 83. The rear end of the transmission rocker arm 84 is provided with a toothed structure and meshes with the output gear of the first transmission gear set 62. The reset torsion spring 85 is located in the middle of the intermediate connecting rod 83. One elastic end of the reset torsion spring 85 is attached to a column fixed relative to the toy body, and the other elastic end of the reset torsion spring 85 is attached to the front column of the transmission swing rod 84.

[0054] In detail, such as Figure 8 and Figure 9As shown, to achieve unidirectional transmission, in this embodiment, the unidirectional transmission component 65 specifically includes a first gear 651, a transmission rod 652, a transmission block 653, a transmission disk 654, a second gear 655, and a transmission shaft 656. One side of the transmission disk 654 is coaxially and fixedly connected to the second gear 655, but not fixed to the transmission shaft 656. In other words, the transmission disk 654 and the second gear 655 can rotate together around the axis. A circular groove is provided on the other side of the transmission disk 654. At least two transmission blocks 653 are provided, and the radial outer edge of each transmission block 653 can abut against the inner side of the circular groove of the transmission disk 654. Specifically, the radial outer edge of each transmission block 653 is an arc shape with the same radius as the circular groove. A sliding groove extending radially from the inside to the outside is provided on the radial inner side of each transmission block 653. The center of the transmission rod 652 and the first gear 651 are respectively fixed to the transmission shaft 656. In other words, the transmission rod 652 and the first gear 651 can rotate together around the axis of the transmission shaft 656. The transmission rod 652 extends radially from the inside out into the groove of each transmission block 653, allowing the transmission block 653 to slide radially relative to the transmission rod 652. Thus, when the first gear 651 and the transmission rod 652 are driven to rotate around the axis, the transmission rod 652 will drive the transmission block 653 to rotate, while the transmission block 653 will make a centrifugal motion radially outward and finally abut against the inner side of the circular groove of the transmission disk 654. Under the action of friction, the transmission block 653 will drive the transmission disk 654 to rotate, and then the second gear 655 will also rotate. Thus, it can be seen that the unidirectional transmission component 65 in this embodiment can be used for forward transmission. At the same time, when the second gear 655 and the transmission disk 654 are driven to rotate around the axis, since the transmission block 653 and the transmission disk 654 are not in contact, the first gear 651 and the transmission rod 652 will not be driven in the reverse direction. Therefore, it can be seen that when the one-way transmission component 65 in this embodiment is in reverse transmission, the second gear 655 and the transmission disk 654 will rotate freely.

[0055] For ease of understanding, the operation of this embodiment is exemplarily described as follows: When the first motor 61 provides rotational power to the opening and closing assembly 80, the output gear of the first transmission gear set 62 drives the transmission rocker arm 84 to rotate counterclockwise around the hinge. The reset torsion spring 85 accumulates elastic potential energy, and simultaneously pulls the maxillary link 81 and the mandibular link 82 away from the head 10 through the intermediate connecting rod 83. The relative angle between the rear ends of the maxillary rocker arm 13 and the mandibular rocker arm 14 decreases, and the maxillary portion 11 and the mandibular portion 12 open. When the first motor 61 stops providing rotational power to the opening and closing assembly 80, the reset torsion spring 85 releases elastic potential energy and pushes the transmission rocker arm 84 to move clockwise around the hinge. Then, through the intermediate connecting rod 83, it pushes the maxillary link 81 and the mandibular link 82 to move closer to the head 10. The relative angle between the rear ends of the maxillary rocker arm 13 and the mandibular rocker arm 14 increases, and the maxillary portion 11 and the mandibular portion 12 close, thereby realizing the reset movement. It is understandable that during the clockwise movement of the transmission lever 84 around the hinge, it will drive the output gear of the first gear set 62 to rotate, and then drive the second gear 655 and the transmission disk 654 to rotate through the other gears, but the first gear 651 and the transmission rod 652 will not rotate.

[0056] As can be seen, the electric simulation toy of this embodiment can realize complex actions such as opening and closing the mouth, maintaining an open mouth and maintaining a closed mouth, forming a lively and realistic action imitation effect. The opening and closing posture and frequency can be controlled by the user, and the changes in action can be realized by the user's operation, thereby enhancing the fun of the toy.

[0057] Furthermore, in the control method of this embodiment, step (1) more specifically includes the following steps:

[0058] (11) In response to the received forward command, the control circuit board 24 controls the first motor 61 to rotate in the first direction, causing the left and right legs 30 to swing. The control circuit board 24 controls the second motor 91 of the two palms 40 to rotate in the third direction, causing the walking wheels 41 of the two palms 40 to rotate forward.

[0059] (12) In response to the received backward command, the control circuit board 24 controls the first motor 61 to rotate in the first direction, causing the left and right legs 30 to swing; the control circuit board 24 controls the second motor 91 of the two palms 40 to rotate in the fourth direction opposite to the third direction, causing the walking wheels 41 of the two palms 40 to rotate backward.

[0060] (13) In response to the received left turn command, the control circuit board 24 controls the first motor 61 to rotate in the first direction, causing the left and right legs 30 to swing; the control circuit board 24 controls the second motor 91 of the left palm 404 to stop rotating or rotate in the fourth direction opposite to the third direction, while the control circuit board 24 controls the second motor 91 of the right palm 40 to rotate in the third direction, causing the electric simulation toy to turn left.

[0061] (14) In response to the received right turn command, the control circuit board 24 controls the first motor 61 to rotate in the first direction, causing the left and right legs 30 to swing; the control circuit board 24 controls the second motor 91 of the right palm 40 to rotate in the third direction, while the control circuit board 24 controls the left palm 40 to stop rotating or rotate in the opposite fourth direction, causing the electric simulation toy to turn right.

[0062] like Figure 6 and Figure 7 As shown in this embodiment, the toy body also includes an atomizer 22, a water tank 21, and an LED bead 23. The water tank 21 is located on the body part 20 and has a cover. The atomizer 22 is located on the body part 20 and is situated behind the upper jaw 11 and lower jaw 12. The atomizer 22 communicates with the water tank 21, and the body part 20 is located to one side of the atomizer 22. In operation, for example, the control circuit board 24 controls the first motor 61 to operate and execute the command to open the mouth. Simultaneously, it also controls the atomizer 22 and the LED bead 23 to operate. The opened mouth will emit smoke colored by the light, thereby enhancing the toy's fun factor.

[0063] Furthermore, in the control method of this embodiment, step (2) more specifically includes:

[0064] In step (2), the control circuit board 24 receives the mouth opening and closing action command, and the control circuit board 24 controls the first motor 61 to rotate in the first direction, while controlling the atomizer 22 to run and controlling the lamp bead 23 to light up.

[0065] Therefore, the electric simulation toy of this embodiment can realize the leg swinging and mouth opening and closing movements respectively by using the different directions of the first motor 61. At the same time, when the leg 30 swings, the rotation direction of the second motors 91 on both sides can also be used to realize the omnidirectional movement of the toy. At the same time, when the mouth opens and closes, the LED beads 23 and the atomizer 22 are used to generate the effect of shooting flames.

[0066] The above embodiments mainly describe the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the present invention. Various changes and modifications can be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
