Description

Technical Field

[0001] The utility model relates to the technical field of toys, in particular to an electronic animal toy. Background Art

[0002] Currently, there are various electronic toys that simulate animals on the market. They are equipped with movements inside, and the motor drives some internal parts of the movement to perform mechanical movements, and cooperate with music to achieve the effect of simulating the swinging hands, feet, and heads of humans and animals. This kind of toy that uses simple internal mechanical movements to produce dynamic and vivid simulation effects on the outside is gradually gaining favor in the market.

[0003] For example, CN202120148465.7 discloses a multi-action electric toy dog, including a head, a trunk, a left forelimb, a right forelimb, a left hind limb, a right hind limb and a tail. A driving mechanism that can drive the head, limbs and tail to swing is arranged inside the trunk, the head is connected to the trunk, a bracket is arranged inside the trunk, and the driving mechanism is arranged on the bracket. The driving mechanism includes a driving motor, a limb driving unit, a head driving unit and a tail driving unit. A housing notch that can extend the limbs, the tail and the head driving unit is arranged on the trunk. The limb driving unit includes a gear set, and an output gear is arranged on the output shaft of the driving motor. The output gear is meshed with the gear set. The driving motor is connected to a selection switch that can control the forward rotation, reverse rotation and shutdown of the driving motor, and the gear set is connected to the head driving unit and the tail driving unit respectively. The advantages of this patent are: it can imitate the dog's walking, tail wagging, and nodding movements, and the user can manually control the type of movement made by the toy dog.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Embodiment 1: As shown in the figure, an electronic animal toy includes a head 2, a trunk 3, two forelimbs 4, two hind limbs 5 and a tail 6. A frame 1 is arranged inside the trunk 3, and a driving movement 7 that can drive the head 2, two forelimbs 4, two hind limbs 5 and tail 6 to move is installed in the frame 1. It also includes a sound-generating airbag 30 and a flip mechanism 8. The head 2 is hinged at the front end of the frame 1, and a swing mechanism 31 for driving the head 2 to swing up and down is arranged between the driving movement 7 and the head 2, so that a mounting cavity with a variable cavity volume is formed between the head 2 and the frame 1. The sound-generating airbag 30 is arranged in the mounting cavity and is used to make a sound when the volume of the mounting cavity is reduced. A flip mechanism 8 for making the electronic animal toy flip is also arranged between the hind limbs 5 and the frame 1.

[0028] Embodiment 2: As shown in the figure, different from Embodiment 1, the swing mechanism 31 includes a driving shaft 32, a curved rod 33 and a hinge 34, one end of the hinge 34 is fixed to the head 2, the middle axis of the hinge 34 is connected to the frame 1, and a connecting rod is fixed to the other end of the hinge 34. The driving shaft 32 is rotatably connected to the side wall of the frame 1 and is controlled by the driving movement 7. An eccentric rod 35 is fixed to the driving shaft 32, one end of the curved rod 33 is movably connected to the eccentric rod 35, and the other end of the curved rod 33 is movably connected to one end of the connecting rod 38.

[0029] In the above structure, one end of the hinge 34 is fixedly connected to the head 2 to realize the rotation of the head 2. The middle part is hinged on the frame 1 so that the head 2 can rotate up and down relative to the frame 1. The driving shaft 32 is rotatably set on the side wall of the frame 1 and can be rotated by the drive of the driving movement 7. An eccentric rod 35 is provided thereon to transmit the rotational motion to the curved rod 33. One end of the curved rod 33 is movably connected to the eccentric rod 35 to facilitate receiving its eccentric motion and converting it. The other end is connected to the connecting rod 38 through a movable joint to realize the driving of the head 2 to rise and fall relative to the frame 1. The eccentric torque provided by the driving shaft 32 is converted into the up and down twisting motion of the head 2 through the curved rod 33. This ensures the flexible movement of the head 2 without affecting the structural rigidity of the whole machine.

[0030] In this embodiment, a pressure rod 36 for contacting the sound-generating airbag 30 is also fixed on the hinge 34 , and a pressure plate 37 is fixed on the side wall of the pressure rod 36 .

[0031] In the above structure, a pressure plate 37 is fixed on one side wall of the pressure rod 36, and the sound-generating airbag 30 is arranged in the installation cavity formed between the head 2 and the frame 1. When the head 2 is pressed downward by the rocking mechanism 31, the hinge 34 drives the pressure rod 36 to move downward. At this time, the pressure plate 37 of the pressure rod 36 will press on the airbag, causing the volume of the airbag to become smaller. Since the gas in the airbag is squeezed, a certain sound will be generated, thereby realizing the sound-generating function.

[0032] Embodiment 3: As shown in the figure, different from Embodiment 2, the somersault mechanism 8 includes a tension spring 9, a pull rod 10, a rotating shaft 11 and a connecting rod 12. One end of the tension spring 9 is connected to the frame 1, and the other end of the tension spring 9 is connected to one end of the pull rod 10. The other end of the pull rod 10 is fixed to the rotating shaft 11. The rotating shaft 11 is horizontally rotatably connected to the rear part of the frame 1, and the end of the rotating shaft 11 passes through the frame 1 and is hinged to one end of the connecting rod 12. The other end of the connecting rod 12 is hinged to the upper part of the hind limb 5. A force release component 13 for driving the connecting rod 12 to rotate is also provided on the frame 1. When the force release component 13 drives the connecting rod 12 to rotate, the rotating shaft 11 rotates accordingly and drives the tension spring 9 to be compressed or stretched through the pull rod 10. When the force release component 13 suddenly releases the connecting rod 12, the tension spring 9 can release the restriction and transfer the potential energy to the hind limb 5 to realize the somersault action.

[0033] The force release assembly 13 includes a driving rod 14 and a driving shaft 15. A slide groove 16 is provided at one end of the driving rod 14. The other end of the driving rod 14 is hinged to the connecting rod 12. The driving shaft 15 is rotatably connected to the side wall of the frame 1 and is controlled by the driving movement 7. One end of the driving shaft 15 is slidably arranged in the slide groove 16. An arc block 17 is also provided on the driving shaft 15. A stopper 18 that cooperates with the arc block 17 is provided inwardly extending from the driving rod 14. The arc block 17 pushes the stopper 18 to move when the driving shaft 15 rotates. When the arc block 17 and the stopper 18 change from a pushing state to a disengaged state, the driving rod 14 is released.

[0034] In the above structure, the driving shaft 15 is rotatable through the control of the driving movement 7, and the arc block 17 thereon can push the block 18 set in the driving rod 14, and the driving rod 14 rotates accordingly. When the driving shaft 15 is at a certain angle, the arc block 17 can be separated from the block 18 due to the structural relationship. At this time, the block 18 can move flexibly with the driving rod 14, so that the two-stage change of the driving rod 14, i.e., the pushing and disengaging, is realized through a simple structural change. This design utilizes the motion coupling and disengagement between the structures to realize the driving control of the driving rod 14 at different stages, and can convert the smooth and orderly rotational motion of the driving shaft 15 into the intermittent push-pull motion of the driving rod 14, and finally release the restriction of the connecting rod 12.

[0035] In this device, the specific principle of realizing the backflip is as follows: one end of the tension spring 9 is connected to the frame 1, and the other end is fixed to the rotating shaft 11 through the pull rod 10. The rotating shaft 11 can rotate smoothly at the rear of the frame 1, thereby driving the tension spring 9 to accumulate momentum, and one end of the connecting rod 12 is connected to the rotating shaft 11, and the other end is hinged to the upper part of the hind limb 5, thereby realizing the linkage between the rotating shaft 11 and the hind limb 5;

[0036] The driving shaft 15 in the force release assembly 13 can rotate through the control of the driving movement 7. The driving shaft 15 is provided with an arc block 17 that pushes the stopper 18. The stopper 18 is arranged in the driving rod 14. When the driving shaft 15 rotates, the arc block 17 thereon pushes the stopper 18 on the driving rod 14, and the driving rod 14 rotates accordingly, driving the connecting rod 12 to rotate. One end of the connecting rod 12 is connected to the rear part of the frame 1 through the rotating shaft 11, which can realize the movement of the rotating shaft 11. The rotating shaft 11 tightens the tension spring 9 inward through the pull rod 10. In this process, the energy of the tension spring 9 is gradually accumulated and stored;

[0037] When the driving shaft 15 is at a certain angle, the arc block 17 disengages from the stop block 18, the driving rod 14 stops, and the tension spring 9 quickly releases energy, which is transmitted to the hind limbs 5 through the rotating shaft 11 and the connecting rod 12, so that the hind limbs 5 quickly rise beyond the balance point, achieving a flipping action, thereby cyclically driving the toy to achieve continuous free flipping of the hind limbs 5, completing the imitation flip effect.

[0038] Embodiment 4: As shown in the figure, the difference from Embodiment 3 is that the stopper 18 has an inclined surface 19, and the inclined surface 19 is inclined relative to the pushing direction of the driving shaft 15.

[0039] The inclined surface 19 is set at an angle relative to the pushing direction of the driving shaft 15, so that when the driving shaft 15 pushes the stopper 18 through the arc block 17, the inclined surface 19 can smoothly guide the arc block 17 to push the stopper 18 inward, and the driving rod 14 can be pushed smoothly. At the same time, when the driving shaft 15 is at a certain position, the edge of the arc block 17 can be more smoothly embedded in the inner corner of the inclined surface 19 of the stopper 18, which makes it easy to separate the arc block 17 and the stopper 18 that were originally firmly connected. In summary, the use of this inclined surface 19 structure can not only ensure that the arc block 17 effectively pushes the stopper 18 during the driving process, but also make it faster and easier for the arc block 17 to leave the stopper 18 when needed, and the driving rod 14 can be released.

[0040] In this embodiment, a first sleeve 20 is vertically arranged at one end of the connecting rod 12, the first sleeve 20 extends into the frame 1 and is coaxially fixed with the rotating shaft 11, and a second sleeve 21 is vertically arranged at the other end of the connecting rod 12, and a hinge hole 22 for the second sleeve 21 to extend into is provided on the hind limb 5, the end of the second sleeve 21 is extended into the hinge hole 22, and a locking screw 23 is connected between the hind limb 5 and the second sleeve 21.

[0041] In the above structure, a first sleeve 20 is vertically arranged at one end of the connecting rod 12. The first sleeve 20 extends into the frame 1 and can be coaxially fixed with the rotating shaft 11, so as to realize a firm connection between the rotating shaft 11 and the connecting rod 12, and ensure that the rotational force can be efficiently transmitted. A second sleeve 21 is vertically arranged at the other end of the connecting rod 12, and a corresponding hinge hole 22 is also provided on the hind limb 5. The second sleeve 21 can accurately extend into the hinge hole 22. This nesting structure is both tight and gapless, and convenient for installation and disassembly. In addition, a locking screw 23 is also added between the hind limb 5 and the second sleeve 21 to further ensure that the two components will not fall off or slide during operation. This greatly improves the overall reliability of the structure, so that the transmission conversion process is smoother and the strength is sufficient. It avoids the loosening problem that may occur when the components are directly connected, and the structure is also more compact, which is more suitable for small-sized designs such as electronic toys.

[0042] Embodiment 5: As shown in the figure, the difference from Embodiment 4 is that a movable hole 24 is provided on the driving rod 14, and the second sleeve 21 passes through the movable hole 24 and is hinged to the hind limb 5.

[0043] In the above structure, when the force release assembly 13 drives the driving rod 14 to move, the second sleeve 21 disposed in the movable hole 24 can rotate freely along with the movement of the hole, thus ensuring that the force pushed by the driving rod 14 can be efficiently transmitted to the hind limb 5. At the same time, the movable hole 24 can also adjust the connection angle between the second sleeve 21 and the hind limb 5 by rotating, providing a wider range of motion for the hind limb 5, which is conducive to achieving a more realistic and smooth somersault action.

[0044] In this embodiment, a mounting base 25 is fixed on the frame 1, and a first protruding shaft 26 extends horizontally on the mounting base 25. One end of the tension spring 9 is sleeved on the first protruding shaft 26, and a first screw 27 for preventing the tension spring 9 from detaching from the first protruding shaft 26 is also screwed on the first protruding shaft 26. A second protruding shaft 28 is provided at one end of the pull rod 10, and one end of the tension spring 9 is sleeved on the second protruding shaft 28. A second screw 29 for preventing the tension spring 9 from detaching from the second protruding shaft 28 is also screwed on the second protruding shaft 28.

[0045] The first cam 26 is provided with a first screw 27 for fixing the tension spring 9, and the second cam 28 is provided with a second screw for fixing the tension spring 9. This can maximize the positioning and fixing performance of the tension spring 9 during work, and the buckling and fixing of the two ends of the tension spring 9 can be completed without other additional components. It also helps the extension and contraction of the tension spring 9, which is beneficial to the transmission of tension. This not only ensures the movement coordination of the mechanism, but also improves the reliability of the tension transmission, thereby realizing the entire flip function.

[0046] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
