Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of swing modules, and in particular to an automatic reset device, a swing module, a simulation toy and a decorative ornament. BACKGROUND

[0002] Simulation toys in the shape of animals (such as pet dogs, cats, bears, etc.), simulation toys in the shape of humans and decorative ornaments are usually provided with swing components (such as the tail, head, ears and forelimbs of the toy) to enhance interest, interactive experience and decorative effect. These components are driven by a motor in combination with a connecting rod, a sliding groove or a cam to achieve periodic swinging (such as left and right swinging of the tail, up and down swinging of the head, etc.) to simulate natural behavior or create a dynamic atmosphere, thereby enhancing the liveliness and attractiveness of the product.

[0003] In the related art, the motor drives the swing component to move synchronously when powered on. However, after power-off, the motor stops immediately and the swing component remains at the position at the instant of power-off, which is likely to deviate from the preset position. Once deviated from the preset position, the product will exhibit an uncoordinated state such as a tilted tail or a drooping head, which destroys the overall visual aesthetics. Although the swing component can be manually reset to the preset position, this method relies on user operation, is inconvenient and has the risk of damaging the internal mechanism due to improper operation. Therefore, there is an urgent need for a device capable of automatic reset.

[0004] It should be noted that the information disclosed in the above background section is intended to enhance the understanding of the background of the present disclosure and may therefore contain information that does not constitute prior art. SUMMARY

DETAILED DESCRIPTION

[0040] For the purpose of promoting the understanding of the present disclosure, the present disclosure will be described in further detail below with reference to the attached drawings. The preferred embodiments of the present disclosure are shown in the drawings. However, the present disclosure can be realized in many different forms and is not limited to the embodiments described herein. The purpose of providing these embodiments is to make the reader more thoroughly and comprehensively understand the present disclosure.

[0041] It should be noted that when an element is referred to as being "fixed" to another element, it can be directly on the other element or there can be an intervening element. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or there can be an intervening element. The terms "vertical", "horizontal", "left", "right", and similar expressions used herein are for the purpose of illustration only and are not intended to be the only implementation.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used in the description herein is for describing particular embodiments only and is not intended to be limiting of the disclosure. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0043] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure will be further described in detail below in combination with specific embodiments:

[0044] As Figure 1 and Figure 2As shown, the automatic reset device 10 of this disclosure includes a swing mechanism 100, which includes a reciprocating swing member 110. The swing member 110 is configured to reciprocate within a predetermined angle range. The swing member 110 is also configured to be connected to an exposed swing component 30 to drive the exposed swing component 30 to reciprocate, thereby simulating natural behavior or creating a dynamic atmosphere. Specifically, the swing mechanism 100 is configured to be driven by the output end of a drive mechanism 20. Under the drive of the drive mechanism 20, the swing member 110 reciprocates within a predetermined angle range, thereby causing the swing component 30 to reciprocate within the predetermined angle range.

[0045] It is understandable that the swinging component 30 can be a body part of an animal simulation toy, such as a tail, ears, head, forelimbs, hindlimbs, etc. The swinging component 30 can also be a body part of a human simulation toy, such as upper limbs, lower limbs, head, etc. The swinging component can also be the entire human simulation toy; for example, if the entire human simulation toy swings back and forth around an upright steel pipe, then the swinging component 30 is the entire human simulation toy. The swinging component 30 can also be a dynamic component of a decorative ornament, such as leaves or branches.

[0046] like Figure 2 As shown, the automatic reset device 10 also includes an elastic reset mechanism 200, which is connected to the swing member 110. The swing member 110 overcomes the elastic force of the elastic reset mechanism 200 during swinging. The elastic reset mechanism 200 is configured to elastically recover when power is off, thereby driving the swing member 110 to swing to a preset position. That is, when the drive mechanism 20 is de-energized, the elastic reset mechanism 200 elastically recovers to drive the swing member 110 to the preset position. In this embodiment, when the automatic reset device 10 is working, the drive mechanism 20 drives the swing member 110 to reciprocate within a predetermined angle range, and the swing member 110 overcomes the elastic force of the elastic reset mechanism 200 during swinging. When the drive mechanism 20 is de-energized, if the swing member 110 deviates from the preset position, the elastic force of the elastic reset mechanism 200 acting on the swing member 110 will drive the swing member 110 to swing to the preset position.

[0047] It should be noted that the angle of the swinging component 110 when it is in the preset position can be arbitrarily selected within the predetermined angle range, but it is necessary to ensure that the product presents a symmetrical structure or other form that meets aesthetic requirements. For example, when the swinging component is a tail, the angle of the swinging component 110 at the preset position is the middle value of the predetermined angle range, or close to the middle value, so that the animal simulation toy has a symmetrical structure when it stops.

[0048] The automatic reset device 10, the swing member 110 overcomes the elastic force of the elastic reset mechanism 200 in the swing process, when the driving mechanism 20 is powered off, the swing member 110 loses the driving force of the driving mechanism 20, if the swing member 110 deviates from the preset position, at this time the elastic force of the elastic reset mechanism 200 will drive the swing member 110 to swing to the preset position, avoiding the exposed swing part 30 after power failure showing unnatural posture, preventing the visual angle beauty and realistic effect of the product due to power failure. And without manual bending can make the swing member 110 swing to the preset position, not only improves the product use convenience, but also reduces the risk of internal mechanism damage due to improper operation.

[0049] As shown in Figure 2 some embodiments, the swing mechanism 100 further comprises a driving member 120, a connecting member 130 and a mounting member 140, the first end of the driving member 120 is configured to be in transmission connection with the power output end of the driving mechanism 20, the connecting member 130 is in rotational connection with the second end of the driving member 120, the connecting member 130 is in transmission connection with the swing member 110, and the swing member 110 is in rotational connection with the mounting member 140, so that the swing member 110 reciprocates within a predetermined angle range. In this embodiment, the driving mechanism 20 is installed on the mounting member 140, when the driving mechanism 20 is driven, the driving member 120 rotates in a certain direction, the driving member 120 drives the connecting member 130 to move, and the connecting member 130 drives the swing member 110 to swing within a predetermined angle range.

[0050] As shown in Figure 2 some embodiments, the elastic reset mechanism 200 is installed on the mounting member 140, so as to ensure that the elastic reset mechanism 200 works at a predetermined position, thereby ensuring that the elastic reset mechanism 200 can drive the swing member 110 to swing to the preset position after power failure.

[0051] As shown in Figure 2 some embodiments, the elastic force of the elastic reset mechanism 200 is adjustable. In this embodiment, when the elastic force of the elastic reset mechanism 200 decays due to long-term use, the elastic force of the elastic reset mechanism 200 can be adjusted to return to the initial value, thereby ensuring that the elastic reset mechanism 200 can drive the swing member 110 to swing to the preset position when powered off.

[0052] As shown in Figure 2 and Figure 3As shown in some embodiments, the elastic reset mechanism 200 is connected to the mounting member 140, and the position of the elastic reset mechanism 200 on the mounting member 140 is adjustable. In this embodiment, the elastic force of the elastic reset mechanism 200 is adjustable by adjusting the position of the elastic reset mechanism 200 on the mounting member 140. When the elastic force of the elastic reset mechanism 200 is attenuated, the elastic force of the elastic reset mechanism 200 can be increased by adjusting the position of the elastic reset mechanism 200, thereby ensuring that the elastic reset mechanism 200 can drive the swing member 110 to swing to the preset position when power is off.

[0053] As shown in some embodiments, Figure 3 and Figure 4 As shown in some embodiments, the mounting member 140 is provided with a position adjustment groove 141. The elastic reset mechanism 200 includes an elastic member 210, a fixing member 220, and a locking member 230. The elastic member 210 is connected to the swing member 110. The fixing member 220 is connected to the elastic member 210 and abuts against the mounting member 140. The fixing member 220 is provided with a connecting hole 221, which is arranged in correspondence with the position adjustment groove 141. The locking member 230 is arranged in the position adjustment groove 141. One end of the locking member 230 is fixedly connected in the connecting hole 221, i.e., the one end of the locking member 230 is located in the connecting hole 221 and is fixedly connected to the fixing member 220. The other end of the locking member 230 abuts against the side of the mounting member 140 away from the fixing member 220, so that the elastic reset mechanism 200 is mounted on the mounting member 140, and the position of the elastic reset mechanism 200 on the mounting member 140 is adjustable, thereby making the elastic force of the elastic reset mechanism 200 adjustable. In this embodiment, when the elastic force of the elastic reset mechanism 200 is attenuated due to long-term use, the position of the elastic reset mechanism 200 relative to the mounting member 140 can be adjusted to restore the elastic force of the elastic reset mechanism 200 to the initial value, thereby ensuring that the elastic reset mechanism 200 can drive the swing member 110 to swing to the preset position when power is off.

[0054] It can be understood that the locking member 230 can be connected in the connecting hole 221 through a threaded structure, an interference abutment, a buckle, or other existing connection structures. The elastic member 210 can be a spring, a rubber structure, a silica gel structure, or other existing elastic structures.

[0055] In other embodiments, the elastic reset mechanism 200 can also omit the fixing member 220 and the locking member 230, the mounting member 140 can omit the position adjustment groove 141, and the elastic member 210 can be directly connected to the mounting member 140. Preferably, the elastic reset mechanism 200 can be a spring, a rubber structure, a silica gel structure, or other existing elastic structures.

[0056] As shown in some embodiments, Figure 3As shown in the drawings, in some embodiments, the mounting member 140 is provided with a limiting groove 142, and the position adjusting groove 141 is arranged in the limiting groove 142. The limiting groove 142 is sized to fit the fixing member 220, and the fixing member 220 is limited in the limiting groove 142, and the position of the fixing member 220 is limited by the limiting groove 142 to ensure that the connecting hole 221 of the fixing member 220 is aligned with the position adjusting groove 141, thereby improving the convenience of connecting the locking member 230 with the fixing member 220, and improving the convenience and efficiency of installing the elastic return mechanism 200 to the mounting member 140.

[0057] As shown in the drawings, Figure 2 In some embodiments, the first end of the connecting member 130 is rotatably connected with the second end of the driving member 120, and the second end of the connecting member 130 is rotatably connected with the swinging member 110, so that the connecting member 130 is in transmission connection with the swinging member 110, and the two rotatable connections of the swinging member 110 are arranged at intervals, thereby forming a crank rocker four-bar linkage mechanism.

[0058] As shown in the drawings, Figure 2 In some embodiments, the elastic return mechanism 200 is connected between the connecting position of the swinging member 110 and the connecting member 130, so that the elastic return mechanism 200 is more likely to drive the swinging member 110, and the required elastic force of the elastic return mechanism 200 is reduced, which is conducive to reducing the performance requirements of the elastic return mechanism 200, and thereby reducing the cost.

[0059] As shown in the drawings, Figure 3 In some embodiments, the swinging mechanism 100 further comprises a hinged member 150, and the second end of the connecting member 130 is rotatably connected with the swinging member 110 through the hinged member 150, and the elastic return mechanism 200 is connected with the hinged member 150, so that the elastic return mechanism 200 is connected between the swinging member 110 and the connecting member 130.

[0060] As shown in the drawings, Figure 2 In some embodiments, the swinging mechanism 100 further comprises a damper 300, and the damper 300 is arranged in one of the driving member 120, the connecting member 130 and the swinging member 110. In this embodiment, when energized, the driving mechanism 20 drives the swinging mechanism 100 to move, so that the instantaneous speed inside the damper 300 is greater than or equal to a preset value, at which time the damper 300 cannot produce damping effect, i.e. the damper 300 cannot absorb the energy generated by the movement of the swinging mechanism 100, thereby avoiding the interruption of the transmission chain, and ensuring that the swinging member can swing back and forth within a predetermined angle.

[0061] When power is off, if the swing member 110 deviates from the preset position, the elastic reset mechanism 200 elastically returns and drives the swing member 110 to swing to the preset position; since the elastic force of the elastic reset mechanism 200 is small, the instantaneous speed inside the damper 300 is < the preset value, the damper 300 can absorb the energy generated by the swing of the swing member 110, so that the transmission chain is interrupted in the damper 300, at this time the swing member 110 can swing without the counter-drive driving mechanism 20, that is, the driving mechanism 20 will not generate resistance to the swing of the swing member 110, even if the counter-drive force required by the driving mechanism 20 is larger, it will not affect the swing of the swing member 110 when power is off, which ensures that the elastic reset mechanism 200 can drive the swing member 110 to the preset position when power is off. At the same time, when power is off, since the driving mechanism 20 will not affect the swing of the swing member 110, the driving mechanism 20 can include a speed reduction mechanism, without using a motor without a speed reduction mechanism, such as a direct-drive motor, which has the same torque but higher cost and larger size, so that not only the cost of the product can be reduced, but also the product can be miniaturized.

[0062] It should be emphasized that the working principle of the damper 300 belongs to the conventional technology in the technical field, and the present disclosure will not be described in detail.

[0063] It can be understood that the driving mechanism 20 needs to overcome the elastic force of the elastic reset mechanism 200 when driving the swing mechanism 100, so the torque required by the driving mechanism 20 needs to be large enough to ensure that the driving mechanism 20 can overcome the elastic reset mechanism 200 and drive the swing mechanism 100.

[0064] As shown in FIGS. Figure 3 and Figure 5 In some embodiments, the damper 300 includes a cylinder body 310 and a piston rod 320, the piston rod 320 movably penetrates the movable cavity 311 of the cylinder body 310, so that the movable cavity 311 is divided into a first cavity 311a and a second cavity 311b. The parts provided with the damper 300 include a first transmission part 131 and a second transmission part 132, the cylinder body 310 is fixedly connected to one of the first transmission part 131 and the second transmission part 132, and the piston rod 320 is fixedly connected to the other one of the first transmission part 131 and the second transmission part 132, so that the first transmission part 131 is connected to the second transmission part 132 through the damper 300, and the first transmission part 131, the damper 300 and the second transmission part 132 together constitute a damping member 600.

[0065] It is understandable that when the instantaneous speed of the piston rod 320 relative to the cylinder 310 is less than the preset value, the piston rod 320 moves relative to the cylinder 310. At this time, the length of the damping member 600 will change, and the first transmission part 131 cannot be connected to the second transmission part 132 through the damper 300. That is, the damper 300 plays the role of absorbing energy. When the instantaneous speed of the piston rod 320 relative to the cylinder 310 is greater than or equal to the preset value, the piston rod 320 is fixed relative to the cylinder 310. The first transmission part 131 is connected to the second transmission part 132 through the damper 300, so that the damper 300 cannot play the role of absorbing energy.

[0066] It should be emphasized that whether the damper 300 has a damping effect depends on the instantaneous speed of the piston rod 320 relative to the cylinder 310. Its motion mechanism is a conventional technology in this field and will not be elaborated on in this disclosure.

[0067] like Figure 5 As shown, in this embodiment, when energized, the driving speed of the drive mechanism 20 is relatively large, so that the instantaneous speed of the piston rod 320 relative to the cylinder 310 is greater than or equal to a preset value, thereby making the first transmission part 131 connected to the second transmission part 132 through the damper 300. That is, the length of the damping member 600 will not change, so that the swing member 110 swings back and forth within a predetermined angle range.

[0068] When the power is off, the driving force of the drive mechanism 20 disappears. If the swing member 110 deviates from the preset position, the elastic reset mechanism 200 elastically recovers and drives the swing member 110 to swing towards the preset position. Since the elastic force of the elastic reset mechanism 200 is small, the swing speed of the swing member 110 is small, so that the instantaneous speed of the piston rod 320 relative to the cylinder 310 is less than the preset value. This causes the piston rod 320 to move relative to the cylinder 310, that is, the length of the damping member 600 changes, so that the damper 300 absorbs the energy generated by the swing of the swing member 110. At this time, the swing member 110 can swing without the reverse drive mechanism 20. That is, the drive mechanism 20 will not generate resistance to the swing of the swing member 110. Even if the torque required for the reverse drive mechanism 20 is large, it will not affect the swing of the swing member 110 when the power is off. This ensures that the elastic reset mechanism 200 can drive the swing member 110 when the power is off, so that the swing member 110 swings to the preset position.

[0069] Meanwhile, when the power is off, since the drive mechanism 20 does not affect the swing of the swinging member 110, the drive mechanism 20 can include a reduction mechanism. There is no need to use a motor without a reduction mechanism, which has the same torque but is more expensive and larger in size. For example, a direct drive motor can reduce the cost of the product and also help to miniaturize the product.

[0070] It can be understood that the reverse drive refers to that the driving mechanism 20 is internally rotated under the action of the external torque on the power output end of the driving mechanism 20 in the power-off state. In the driving mechanism 20 with a reduction, i.e. in the reduction motor, the torque output by the motor is enlarged and output through the reduction mechanism, and in the power-off state, the external torque is reduced by the reduction mechanism, so that the torque required for the reverse drive of the reduction motor is large.

[0071] As shown in Figure 5 In some embodiments, the cylinder body 310 is provided with a first communication hole 312 and a second communication hole 313 at two ends thereof, and the first communication hole 312 communicates with the second communication hole 313. The two ends of the movable cavity 311 communicate with the first communication hole 312 and the second communication hole 313, respectively, i.e. the first cavity 311a communicates with the first communication hole 312, and the second cavity 311b communicates with the second communication hole 313. In this embodiment, the first cavity 311a is located at one end of the cylinder body 310 away from the extension end of the piston rod 320. When the piston rod 320 is retracted into the cylinder body 310, the volume of the first cavity 311a decreases, and the medium in the first cavity 311a is discharged through the first communication hole 312. At the same time, the volume of the second cavity 311b increases, and the medium discharged from the first communication hole 312 flows back to the second cavity 311b through the second communication hole 313, thereby ensuring that the piston rod 320 can smoothly move towards the direction of being retracted into the cylinder body 310. When the piston rod 320 extends out of the cylinder body 310, the volume of the second cavity 311b decreases, and the medium in the second cavity 311b is discharged through the second communication hole 313. At the same time, the volume of the first cavity 311a increases, and the medium discharged from the second communication hole 313 flows back to the first cavity 311a through the first communication hole 312, thereby ensuring that the piston rod 320 can smoothly move towards the direction of extending out of the cylinder body 310.

[0072] Preferably, the damper 300 further comprises a communication pipe, and the first communication hole 312 and the second communication hole 313 communicate with each other through the communication pipe.

[0073] As shown in Figure 5 In some embodiments, the damper 300 further comprises a first on-off valve (not shown) arranged in the first communication hole 312 and used for limiting the exhaust rate of the first communication hole 312.

[0074] As shown in Figure 5 In some embodiments, the damper 300 further comprises a second on-off valve (not shown) arranged in the second communication hole 313 and used for limiting the exhaust rate of the second communication hole 313.

[0075] As shown in Figure 5As shown, in some embodiments, the medium inside the cylinder 310 is gas. Of course, the medium inside the cylinder 310 is not limited to gas. For example, in some embodiments, the medium inside the cylinder 310 is liquid, which can be oil, water, etc., and the liquid is preferably hydraulic oil.

[0076] like Figure 5 As shown, in some embodiments, when the medium in the cylinder is liquid, the piston rod 320 has a double rod structure (not shown), that is, the piston rod 300 passes through the first cavity 311a and the second cavity 311b respectively, so that the piston rod 320 can extend and retract normally relative to the cylinder 310.

[0077] like Figure 3 As shown, in some embodiments, the damper 300 is disposed on the connector 130. Of course, in other embodiments, the damper 300 may be disposed on the driving member 120 or the oscillating member 110.

[0078] According to the above embodiments, when the power is off, if the swing member 110 deviates from the preset position, the length of the damping member 600 will change after the swing member 110 swings to the preset position; when the drive mechanism 20 is restarted, the swing stroke of the swing member 110 is different from the preset angle range because the length of the damping member 600 has changed.

[0079] To ensure that the oscillating component 110 can maintain its reciprocating oscillation within a preset angle range after being powered on again, such as Figure 6 As shown, in some embodiments, the automatic reset device 10 further includes a first limiting member 400 and a second limiting member 500, which are respectively disposed on opposite sides of the swing member 110 to limit the swing stroke of the swing member 110.

[0080] like Figure 5 and Figure 6 As shown, in this embodiment, when the drive mechanism 20 is powered on again, if the length of the damping member 600 is different from the preset value, the swing stroke of the swing member 110 will be intersected with the preset swing stroke. During the swing, the swing member 110 will abut against the first limiting member 400 or the second limiting member 500. In order to restore the length of the damping member 600 to the preset value, before the swing member 110 abuts against the first limiting member 400 or the second limiting member 500, the drive speed of the drive mechanism 20 is reduced, so that when the swing member 110 abuts against the first limiting member 400 or the second limiting member 500, the instantaneous speed of the piston rod 320 relative to the cylinder 310 is less than the preset value, thereby causing the piston rod 320 to move relative to the cylinder 310, so that the length of the damping member 600 is restored to the preset value, and the swing member 110 swings back and forth within the preset angle range again.

[0081] It is understood that the aforementioned speed control belongs to the prior art and is not within the scope of protection of this disclosure, therefore this disclosure will not elaborate further.

[0082] like Figure 6 As shown, in some embodiments, the swing mechanism 100 includes a driving member 120, a connecting member 130, and a mounting member 140. The first end of the driving member 120 is configured to be driveably connected to the power output end of the drive mechanism 20. The connecting member 130 includes a first transmission part 131 and a second transmission part 132. The first transmission part 131 is rotatably connected to the swing member 110, which is also rotatably connected to the mounting member 140. The second transmission part 132 is rotatably connected to the second end of the driving member 120.

[0083] Furthermore, the automatic reset device 10 also includes a damper 300, which includes a cylinder 310 and a piston rod 320. The piston rod 320 is movably disposed in the movable cavity 311 of the cylinder 310. The cylinder 310 is fixedly connected to one of the first transmission part 131 and the second transmission part 132, and the piston rod 320 is fixedly connected to the first transmission part 131 and the other transmission part.

[0084] In this embodiment, when energized, the driving speed of the drive mechanism 20 is relatively high, so that the instantaneous speed of the piston rod 320 relative to the cylinder 310 is greater than or equal to a preset value. This causes the first transmission part 131 to be connected to the second transmission part 132 via the damper 300, meaning that the length of the damping member 600 does not change. At this time, the drive mechanism 20 drives the active member 120, the active member 120 drives one of the first transmission part 131 and the second transmission part 132, one of the first transmission part 131 and the second transmission part 132 drives the damper 300, the damper 300 drives the other of the first transmission part 131 and the second transmission part 132, and the other of the first transmission part 131 and the second transmission part 132 drives the swing member 110, causing the swing member 110 to swing back and forth within a predetermined angle range.

[0085] When power is off, the driving force of the driving mechanism 20 disappears, and if the swing member 110 deviates from the preset position, the elastic return mechanism 200 elastically returns and drives the swing member 110 to swing to the preset position. Since the elastic force of the elastic return mechanism 200 is small, the swing speed of the swing member 110 is small, so that the instantaneous speed of the piston rod 320 relative to the cylinder body 310 is less than the preset value, and thus the piston rod 320 moves relative to the cylinder body 310, i.e. the length of the damping member 600 changes, so that the damper 300 absorbs the energy generated by the swing of the swing member 110. At this time, the swing member 110 can swing without driving the driving mechanism 20, i.e. the driving mechanism 20 will not generate resistance to the swing of the swing member 110, even if the torque required to drive the driving mechanism 20 is large, it will not affect the swing of the swing member 110 when power is off, ensuring that the elastic return mechanism 200 can drive the swing member 110 to swing to the preset position when power is off.

[0086] At the same time, when power is off, the driving mechanism 20 will not affect the swing of the swing member 110, so the driving mechanism 20 can include a speed reduction mechanism, without using a motor without a speed reduction mechanism, such as a direct drive motor, which has the same torque but higher cost and larger size. Thus, not only can the cost of the product be reduced, but also the product can be miniaturized.

[0087] It can be understood that the specific structure of the swing mechanism 100 is not limited to the structure of the above-mentioned embodiments. For example, as shown in Figure 7 In some embodiments, the swing mechanism 100 further includes a swing member 110, a driving member 120, a connecting member 130, and a mounting member 140, the first end of the driving member 120 is configured to be in transmission connection with the power output end of the driving mechanism 20, the connecting member 130 is in rotational connection with the second end of the driving member 120, the connecting member 130 is in transmission connection with the swing member 110, and the swing member 110 is in rotational connection with the mounting member 140. Further, the connecting member 130 is slidingly connected to the swing member 110 along the extension direction of the swing member 110, so that the connecting member 130 is in transmission connection with the swing member 110, and the swing mechanism 100 forms a crank slider mechanism. In this way, when the driving member 120 rotates in the same direction, the swing member 110 can reciprocate within a predetermined angle range.

[0088] For example, in some embodiments, the swing mechanism 100 further includes a cam (not shown), the cam is in transmission connection with the power output end of the driving mechanism 20, and the cam is in transmission connection with the swing member 110, so that the cam drives the swing member 110 to swing. In this embodiment, the driving mechanism 20 drives the cam to rotate, and the cam drives the swing member 110 to swing.

[0089] For example, in some embodiments, the swing mechanism 100 further comprises a driving cylinder (not shown in the figure), which is configured to be in transmission connection with the power output end of the driving mechanism 20, and the surface of the driving cylinder is provided with a sliding groove, and one end of the swing piece 110 is slidably arranged in the sliding groove. In this embodiment, when the driving mechanism 20 is driven, the driving cylinder rotates, and the sliding groove drives the swing piece 110 to swing.

[0090] As shown in Figure 3 the present disclosure further provides a swing module, which comprises the driving mechanism 20 and the automatic reset device 10 according to any one of the above embodiments, and the swing mechanism 100 is in transmission connection with the power output end of the driving mechanism 20. Further, the driving mechanism 20 comprises a motor 700 and a speed reduction mechanism 800, the power input end of the speed reduction mechanism 800 is connected to the output shaft of the motor 700, and the power input end of the swing mechanism 100 is connected to the power output end of the speed reduction mechanism 800.

[0091] In some embodiments, the driving mechanism 20 is a permanent magnet type motor. The permanent magnet type motor is easier to reverse drive after power failure, and can be driven to rotate by a small external force. Therefore, in the case of omitting the damper 300, the elastic reset force can drive the swing mechanism 100 to reverse drive the driving mechanism 20, thereby ensuring that the elastic reset mechanism 200 can drive the swing piece 110 to swing to the preset position. Preferably, the driving mechanism 20 is a direct drive motor.

[0092] The present disclosure further provides a simulation toy, which comprises a limb component and the swing module according to any one of the above embodiments, the limb component is fixedly connected to the swing piece 110, and the limb component is driven by the swing piece 110 to reciprocate within a preset angle range, so as to simulate the swing of the limb. It can be understood that the limb component can be an upper limb, a lower limb, a forelimb, a hind limb, a head, a tail or other limb components.

[0093] The present disclosure further provides a decorative swing, which comprises a dynamic component and the swing module according to any one of the above embodiments, the dynamic component is fixedly connected to the swing piece 110, and the dynamic component is driven by the swing piece 110 to reciprocate within a preset angle range. It can be understood that the dynamic component can be a leaf, a branch, a pendulum or a movable component of other existing decorative swings.

[0094] Compared with the prior art, the present disclosure has at least the following advantages:

[0095] The automatic reset device 10, the swing module, the simulation toy and the decorative ornament described above, the swing piece 110 overcomes the elastic force of the elastic reset mechanism 200 in the swing process, when the driving mechanism 20 is powered off, the swing piece 110 loses the driving force of the driving mechanism 20, if the swing piece 110 deviates from the preset position, at this time the elastic force of the elastic reset mechanism 200 will drive the swing piece 110 to swing to the preset position, avoiding the exposed swing part 30 after power failure showing unnatural posture, preventing the visual angle beauty and the simulation effect of the product from being reduced due to power failure. And without manually moving, the swing piece 110 can be swung to the preset position, which not only improves the convenience of the product, but also reduces the risk of internal mechanism damage caused by improper operation.

[0096] The above-described embodiments only express several embodiments of the present disclosure, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the disclosed patent. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present disclosure, several modifications and improvements can be made, which belong to the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure patent should be subject to the appended claims.
