Automatic reset device, swing module, simulation toy and decorative ornament

Abstract

The present disclosure provides an automatic reset device, a swing module, a simulation toy and a decorative ornament. The automatic reset device comprises a swing mechanism, the swing mechanism comprises a swing piece capable of reciprocating swing, and the swing piece is configured to reciprocate within a predetermined angle range; the automatic reset device further comprises an elastic reset mechanism connected to the swing piece, and the elastic reset mechanism is configured to elastically recover when power is off, so as to drive the swing piece to swing to a preset position. The swing piece overcomes the elastic force of the elastic reset mechanism during the swing process, and when the driving mechanism is powered off, the swing piece loses the driving force of the driving mechanism. If the swing piece deviates from the preset position, the elastic force of the elastic reset mechanism will drive the swing piece to swing to the preset position, thereby avoiding the swing piece from presenting an unnatural posture after power is off. In addition, the swing piece can be swung to the preset position without manual operation, which not only improves the convenience of product use, but also reduces the risk of internal mechanism damage caused by improper operation.

Description

Technical Field

[0001] This disclosure relates to the technical field of rocking modules, and in particular to an automatic reset device, a rocking module, a simulation toy, and a decorative ornament. Background Technology

[0002] Animal-shaped lifelike toys (such as pet dogs, cats, and bears), human-shaped lifelike toys, and decorative ornaments often feature swinging parts (such as the toy's tail, head, ears, and forelimbs) to enhance fun, interactive experience, and decorative effect. These parts use motors in conjunction with linkages, slides, or cams to achieve periodic swinging (such as the tail swinging left and right, or the head swaying up and down) to simulate natural behavior or create a dynamic atmosphere, thereby enhancing the product's vividness and appeal.

[0003] In related technologies, when power is applied, the motor drives the swinging component to move synchronously; however, after power is cut off, the motor stops immediately, and the swinging component remains at the position it was at the moment of power failure, easily deviating from the preset position. Once it deviates from the preset position, the product will exhibit an uncoordinated state such as a crooked tail and a drooping head, ruining the overall visual aesthetics. Although the swinging component can be manually reset to the preset position, this method relies on user operation, is inconvenient, and carries the risk of damaging the internal mechanism due to improper operation. Therefore, there is an urgent need for a device that can achieve automatic reset.

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

[0005] The purpose of this disclosure is to overcome at least one of the above-mentioned technical defects and to provide an automatic reset device, a rocking module, a simulation toy, and a decorative ornament.

[0006] The purpose of this disclosure is achieved through the following technical solution:

[0011] In some implementations, the mounting element is provided with a position adjustment groove; the elastic reset mechanism includes:

[0012] An elastic element is connected to the swinging element;

[0013] The fastener, connected to the elastic element and abutting against the mounting element, is provided with a connecting hole corresponding to the position adjustment groove; and

[0014] A locking element is inserted into the position adjustment groove. One end of the locking element is fixedly connected to the connection hole, and the other end of the locking element abuts against the side of the mounting component away from the fixing component.

[0015] In some implementations, the mounting component is provided with a limiting groove, the position adjustment groove is disposed within the limiting groove, and the fixing component is limited to the limiting groove.

[0016] In some implementations, the first end of the connector is rotatably connected to the second end of the driving member, and the second end of the connector is rotatably connected to the swing member, so that the connector and the swing member are connected in a transmission manner.

[0017] In some implementations, the elastic reset mechanism is connected at the connection between the swing member and the connecting member.

[0018] In some implementations, the connector is slidably connected to the swing member along the extension direction of the swing member, so that the connector and the swing member are connected in a transmission manner.

[0019] In some implementations, the automatic reset device further includes a damper disposed on one of the driving member, the connecting member, and the oscillating member.

[0020] In some implementations, the damper includes a cylinder and a piston rod, the piston rod being movably disposed within the movable cavity of the cylinder;

[0021] The component equipped with the damper includes a first transmission part and a second transmission part, the cylinder body is fixedly connected to one of the first transmission part and the second transmission part, and the piston rod is fixedly connected to the other of the first transmission part and the second transmission part.

[0022] In some implementations, the cylinder body has a first connecting hole and a second connecting hole at both ends, the first connecting hole and the second connecting hole are connected, and the two ends of the movable cavity are connected to the first connecting hole and the second connecting hole, respectively.

[0023] In some implementations, the automatic reset device further includes a first limiting member and a second limiting member, which are respectively disposed on opposite sides of the swing member to limit the swing stroke of the swing member.

[0024] In some implementations, the swing mechanism further includes an active member, a connecting member, and a mounting member.

[0029] Compared with the prior art, this disclosure has at least the following advantages:

[0030] During the swinging process, the oscillating component overcomes the elastic force of the elastic reset mechanism. When the drive mechanism is de-energized, the oscillating component loses its driving force. If the oscillating component deviates from the preset position, the elastic force of the reset mechanism will cause it to swing back to the preset position. This prevents the exposed oscillating component from exhibiting an unnatural posture after power failure, thus preventing a reduction in the product's aesthetic appeal and realism due to power loss. Furthermore, the oscillating component can be swung to the preset position without manual manipulation, improving ease of use and reducing the risk of damage to the internal mechanism due to improper operation.

Detailed Implementation

[0040] To facilitate understanding of this disclosure, a more complete description will be provided below with reference to the accompanying drawings. Preferred embodiments of this disclosure are shown in the drawings. However, this disclosure can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to provide the reader with a more thorough and complete understanding.

[0041] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may 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 may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible 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 herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0043] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0044] like 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] In the aforementioned automatic reset device 10, the swinging component 110 overcomes the elastic force of the elastic reset mechanism 200 during swinging. When the drive mechanism 20 is de-energized, the swinging component 110 loses the driving force of the drive mechanism 200. If the swinging component 110 deviates from the preset position, the elastic force of the elastic reset mechanism 200 will drive the swinging component 110 to swing back to the preset position. This prevents the exposed swinging component 30 from exhibiting an unnatural posture after power failure, thus preventing a reduction in the product's aesthetic appeal and realistic effect due to power failure. Furthermore, the swinging component 110 can be swung to the preset position without manual manipulation, improving the product's ease of use and reducing the risk of damage to the internal mechanism due to improper operation.

[0049] like Figure 2 As shown, in some embodiments, the swing mechanism 100 further includes an active member 120, a connecting member 130, and a mounting member 140. The first end of the active member 120 is configured to be driveably connected to the power output end of the drive mechanism 20. The connecting member 130 is rotatably connected to the second end of the active member 120 and driveably connected to the swing member 110. The swing member 110 is rotatably connected to the mounting member 140, causing the swing member 110 to reciprocate within a predetermined angle range. In this embodiment, the drive mechanism 20 is mounted on the mounting member 140. When the drive mechanism 20 is driven, the active member 120 rotates cyclically in a certain direction, driving the connecting member 130 to move, and the connecting member 130 drives the swing member 110 to swing within a predetermined angle range.

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

[0051] like Figure 2 As shown, in 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 decreases due to prolonged use, the elastic force of the elastic reset mechanism 200 can be adjusted to restore its initial value, thereby ensuring that the elastic reset mechanism 200 can drive the swing member 110 to swing to a preset position when the power is off.

[0052] like 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, by adjusting the position of the elastic reset mechanism 200 on the mounting member 140, the elastic force of the elastic reset mechanism 200 is adjustable. When the elastic force of the elastic reset mechanism 200 decreases, its elastic force 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 a preset position when the power is off.

[0053] like 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 the fixing member 220 also abuts against the mounting member 140. The fixing member 220 is provided with a connecting hole 221, which corresponds to the position adjustment groove 141. The locking member 230 passes through the position adjustment groove 141. One end of the locking member 230 is fixedly connected to the connecting hole 221, that is, one end of the locking member 230 is located in the connecting hole 221 and fixedly connected to the fixing member 220. The other end of the locking member 230 abuts against the side of the mounting member 140 opposite to 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 decreases due to long-term use, the position of the elastic reset mechanism 200 relative to the mounting member 140 can be adjusted so that the elastic force of the elastic reset mechanism 200 returns to its initial value, thereby ensuring that the elastic reset mechanism 200 can drive the swing member 110 to swing to a preset position when the power is off.

[0054] It is understood that the locking element 230 can be connected to the connecting hole 221 via a threaded structure, interference fit, snap-fit, or other existing connection structure. The elastic element 210 can be a spring, a rubber structure, a silicone structure, or other existing elastic structure.

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

[0056] like Figure 3As shown, in some embodiments, the mounting member 140 is provided with a limiting groove 142, and a position adjustment groove 141 is disposed within the limiting groove 142. The size of the limiting groove 142 is adapted to the size of the fixing member 220, and the fixing member 220 is limited in the limiting groove 142. The limiting groove 142 restricts the position of the fixing member 220, ensuring that the connecting hole 221 of the fixing member 220 is aligned with the position adjustment groove 141. This improves the convenience of connecting the locking member 230 and the fixing member 220, and improves the convenience and efficiency of installing the elastic reset mechanism 200 onto the mounting member 140.

[0057] like Figure 2 As shown, in some embodiments, the first end of the connector 130 is rotatably connected to the second end of the driving member 120, and the second end of the connector 130 is rotatably connected to the swing member 110, making the connector 130 and the swing member 110 drively connected. The two rotatable connections of the swing member 110 are spaced apart, thus making the rocking mechanism 100 a crank-rocker four-bar linkage. This allows the swing member 110 to reciprocate within a predetermined angle range when the driving member 120 rotates in the same direction. Preferably, the swing member 110, the driving member 120, and the connector 130 are all rod-shaped, making the structure of the rocking mechanism 100 more compact and improving space utilization.

[0058] like Figure 2 As shown, in some embodiments, the elastic reset mechanism 200 is connected to the connection between the swing member 110 and the connector 130, making it easier for the elastic reset mechanism 200 to drive the swing member 110, reducing the elastic force required by the elastic reset mechanism 200, which helps to reduce the performance requirements of the elastic reset mechanism 200 and thus reduce costs.

[0059] like Figure 3 As shown, in some embodiments, the rocking mechanism 100 further includes a hinge 150, the second end of the connector 130 is rotatably connected to the rocking member 110 via the hinge 150, and the elastic reset mechanism 200 is connected to the hinge 150, such that the elastic reset mechanism 200 is connected between the rocking member 110 and the connector 130.

[0060] like Figure 2 As shown, in some embodiments, the swing mechanism 100 further includes a damper 300, which is disposed in one of the driving member 120, the connecting member 130, and the swing member 110. In this embodiment, when energized, the driving mechanism 20 drives the swing mechanism 100 to move, so that the instantaneous speed inside the damper 300 is greater than or equal to a preset value. At this time, the damper 300 cannot play a damping effect, that is, the damper 300 will not absorb the energy generated by the movement of the swing mechanism 100, thus avoiding the interruption of the transmission chain and ensuring that the swing member can swing back and forth within a preset 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 back to the preset position. Because the elastic force of the elastic reset mechanism 200 is small, the instantaneous velocity inside the damper 300 is less than the preset value. The damper 300 can absorb the energy generated by the swing of the swing member 110, causing the transmission chain to be interrupted at the damper 300. At this time, the swing member 110 can swing without the need for the reverse drive mechanism 20, meaning the drive mechanism 20 will not generate resistance to the swing of the swing member 110. Even if the reverse drive force required by the drive mechanism 20 is large, it will not affect the swing of the swing member 110 when power is off, ensuring that the elastic reset mechanism 200 can drive the swing member 110 to the preset position when power is off. Simultaneously, since the drive mechanism 20 does not affect the swing of the swing member 110 when power is off, the drive mechanism 20 can include a reduction mechanism, eliminating the need for a motor without a reduction mechanism, such as a direct-drive motor, which has the same torque but is more expensive and larger. This not only reduces product cost but also facilitates product miniaturization.

[0062] It should be emphasized that the working principle of the damper 300 is a conventional technology in this field, and this disclosure will not elaborate further.

[0063] It is understandable that the drive mechanism 20 needs to overcome the elastic force of the elastic reset mechanism 200 when driving the rocking mechanism 100. Therefore, the torque of the drive mechanism 20 must be large enough to ensure that the drive mechanism 20 can overcome the elastic reset mechanism 200 and drive the rocking mechanism 100.

[0064] like Figure 3 and Figure 5 As shown, in some embodiments, the damper 300 includes a cylinder 310 and a piston rod 320. The piston rod 320 movably passes through the movable cavity 311 of the cylinder 310, dividing the movable cavity 311 into a first cavity 311a and a second cavity 311b. The component with the damper 300 includes a first transmission part 131 and a second transmission part 132. 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 other of the first transmission part 131 and the second transmission part 132, such that the first transmission part 131 is connected to the second transmission part 132 through the damper 300. The first transmission part 131, the damper 300, and the second transmission part 132 together form the damping component 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 reverse drive refers to the situation where, when the drive mechanism 20 is de-energized, external torque acts on the power output end of the drive mechanism 20, causing the drive mechanism 20 to rotate internally. In the drive mechanism 20 with reduction gear, i.e., in the geared motor, since the torque output by the motor is amplified and output through the reduction mechanism, when the power is de-energized, the external torque is reduced by the reduction mechanism, resulting in a larger torque required for the reverse drive geared motor.

[0071] like Figure 5 As shown, in some embodiments, the cylinder body 310 has a first connecting hole 312 and a second connecting hole 313 at both ends, with the first connecting hole 312 and the second connecting hole 313 communicating with each other. The movable cavity 311 has both ends connected to the first connecting hole 312 and the second connecting hole 313, that is, the first cavity 311a is connected to the first connecting hole 312, and the second cavity 311b is connected to the second connecting hole 313. In this embodiment, the first cavity 311a is located at the end of the cylinder body 310 away from the extended end of the piston rod 320. When the piston rod 320 retracts 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 connecting hole 312. Simultaneously, the volume of the second cavity 311b increases, and the medium discharged from the first connecting hole 312 flows back to the second cavity 311b through the second connecting hole 313, ensuring that the piston rod 320 can move smoothly in the direction of retraction into the cylinder body 310. When the piston rod 320 extends out of the cylinder 310, the volume of the second chamber 311b decreases, and the medium in the second chamber 311b is discharged through the second connecting hole 313. Simultaneously, the volume of the first chamber 311a increases, and the medium discharged from the second connecting hole 313 flows back to the first chamber 311a through the first connecting hole 312, ensuring that the piston rod 320 can move smoothly in the direction of extending out of the cylinder 310.

[0072] Preferably, the damper 300 further includes a connecting pipe, which is disposed outside the cylinder body 310, and the first connecting hole 312 and the second connecting hole 313 are connected through the connecting pipe.

[0073] like Figure 5 As shown, in some embodiments, the damper 300 further includes a first switching valve (not shown), which is disposed within the first connecting hole 312 for limiting the exhaust rate of the first connecting hole 312.

[0074] like Figure 5 As shown, in some embodiments, the damper 300 further includes a second switching valve (not shown) disposed within the second communication hole 313 for limiting the exhaust rate of the second communication hole 313.

[0075] like 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 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 of the drive mechanism 20 is large, it will not affect the swing of the swing member 110 when the power is off, ensuring 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.

[0086] 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.

[0087] It is understood that the specific structure of the rocking mechanism 100 is not limited to the structure of the above embodiment. For example, as Figure 7 As shown, in some embodiments, the rocking mechanism 100 further includes a rocking 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 driveably connected to the power output end of the drive mechanism 20. The connecting member 130 is rotatably connected to the second end of the driving member 120 and driveably connected to the rocking member 110. The rocking member 110 is rotatably connected to the mounting member 140. Further, the connecting member 130 is slidably connected to the rocking member 110 along its extension direction, thus creating a crank-slider mechanism. In this way, when the driving member 120 rotates in the same direction, the rocking member 110 can reciprocate within a predetermined angle range.

[0088] For example, in some embodiments, the rocking mechanism 100 further includes a cam (not shown), which is driven to the power output end of the drive mechanism 20 and to the rocking member 110, thereby driving the rocking member 110 to rock. In this embodiment, the drive mechanism 20 drives the cam to rotate, and the cam drives the rocking member 110 to rock.

[0089] For example, in some embodiments, the swing mechanism 100 further includes a drive cylinder (not shown), which is configured to be drively connected to the power output end of the drive mechanism 20. The surface of the drive cylinder is provided with a groove, and one end of the swing member 110 is slidably disposed in the groove. In this embodiment, when the drive mechanism 20 is driven, the drive cylinder rotates, causing the groove to drive the swing member 110 to swing.

[0090] like Figure 3 As shown, this disclosure also provides a swing module, including a drive mechanism 20 and an automatic reset device 10 as described in any of the above embodiments. The swing mechanism 100 is drively connected to the power output end of the drive mechanism 20. Further, the drive mechanism 20 includes a motor 700 and a reduction mechanism 800. The power input end of the 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 reduction mechanism 800.

[0091] In some embodiments, the drive mechanism 20 is a permanent magnet motor. Permanent magnet motors are relatively easy to reverse drive after power failure, and their output shaft can be rotated with a small external force. Thus, without omitting the damper 300, the elastic reset force can drive the swing mechanism 100, causing the swing mechanism 100 to reverse drive the drive mechanism 20, thereby ensuring that the elastic reset mechanism 200 can drive the swing member 110 to swing to a preset position. Preferably, the drive mechanism 20 is a direct drive motor.

[0092] This disclosure also provides a simulation toy, including limb parts and the rocking module described in any of the above embodiments. The limb parts are fixedly connected to the rocking member 110, and the rocking member 110 drives the limb parts to swing back and forth within a preset angle range to simulate the swinging of limbs. It is understood that the limb parts can be upper limbs, lower limbs, forelimbs, hind limbs, heads, tails, or other limb parts.

[0093] This disclosure also provides a decorative ornament, including a dynamic component and the swing module described in any of the above embodiments. The dynamic component is fixedly connected to the swing member 110, and the swing member 110 drives the dynamic component to swing back and forth within a preset angle range. It can be understood that the dynamic component can be a leaf, a branch, a pendulum, or a movable part of other existing decorative ornaments.

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

[0095] The aforementioned automatic reset device 10, swing module, simulation toy, and decorative ornament all feature a swing component 110 that overcomes the elastic force of the elastic reset mechanism 200 during swinging. When the drive mechanism 20 is de-energized, the swing component 110 loses its driving force. If the swing component 110 deviates from the preset position, the elastic force of the elastic reset mechanism 200 will cause the swing component 110 to swing back to the preset position. This prevents the exposed swing component 30 from exhibiting an unnatural posture after power failure, thus preventing a reduction in the product's aesthetic appeal and realism due to power loss. Furthermore, the swing component 110 can be swung to the preset position without manual manipulation, improving the product's ease of use and reducing the risk of damage to the internal mechanism due to improper operation.

[0096] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
