Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of children's entertainment equipment, and in particular to a swinging device and a wooden horse rocking chair. BACKGROUND

[0002] Children's entertainment facilities are special equipment designed to promote the physical development, sensory coordination and psychological pleasure of children, and are widely used in families, kindergartens, early education centers and public places. Among them, the wooden horse rocking chair, as a classic and popular rocking toy for infants and young children, is usually composed of a bionic horse-shaped seat and an arc-shaped base, which simulates horseback riding by reciprocating forward and backward, and has both entertainment and early exercise training functions. Its simple structure and easy operation can effectively exercise the children's balance, core muscle control and spatial perception ability, while bringing a sense of safety and emotional comfort, so it occupies an important position in the toy market for young children.

[0003] The swinging function of the existing wooden horse rocking chair mainly depends on the transmission assembly at the bottom of the rocking chair. The assembly is usually composed of two or more articulated arms, which are connected to each other by a pin shaft or a rotating shaft, and form a movable connection structure with the seat and the base. When the child swings back and forth on the rocking chair, the articulated arms make reciprocating swing around the hinge point, driving the overall structure to move along an arc trajectory, thereby realizing the effect of up and down or forward and backward swing, mainly relying on mechanical linkage to ensure the stability and repeatability of the movement, which is the most common driving mode in current wooden horse rocking chairs.

[0004] However, in actual use, the existing articulated transmission assembly has obvious structural defects. Since the articulated arms are connected by hinges and the freedom of turning direction is limited when transmitting, when the child swings quickly or is pushed by external force, the system is prone to out-of-sync movement of the two sides of the articulated arms due to inertia, resulting in incorrect swing direction or phase deviation. This out-of-sync phenomenon not only destroys the smoothness of the swing, produces obvious jerking and abnormal noise, and affects the riding comfort, but in severe cases, it may cause deformation of the swing arm, wear and even breakage of the hinge pin, resulting in structural instability or connection failure, and safety hazards. In addition, long-term asynchronous swing can also accelerate the fatigue damage of the hinge part and shorten the service life of the equipment. SUMMARY

[0005] The present application provides a swinging device and a wooden horse rocking chair, which solves the technical problem of motion interference caused by incorrect swing direction in the existing wooden horse rocking chair with multiple articulated transmission assemblies by adopting an eccentric rotation driving combined with a lever type link transmission structure, and realizes stable and smooth swinging movement. The technical scheme is as follows:

[0006] In a first aspect, the embodiments of the present application provide a swinging device, comprising: a base; a driving mechanism mounted on the base, the driving mechanism comprising: a rotating shaft and two adapter wheels, the rotating shaft being driven to rotate by the driving mechanism, and the two adapter wheels being eccentrically arranged at two ends of the rotating shaft respectively; a supporting mechanism mounted on the base and located on a radial side of the rotating shaft, both sides of the supporting mechanism being provided with supporting components; and two connecting rods, the middle parts of the connecting rods being supported on the corresponding supporting components respectively to divide the connecting rods into first segments and second segments; the first segments being located between the supporting components and the adapter wheels, and the end parts of the first segments being rotationally connected with the adapter wheels on the same side, and the second segments being located on the sides of the supporting components away from the adapter wheels;

[0007] The two adapter wheels are driven to synchronously eccentrically rotate by the rotating shaft to drive the two connecting rods to swing around the corresponding supporting components, and the swinging directions of the first segments are opposite to the swinging directions of the second segments.

[0008] In an embodiment, the swinging device further comprises: a mounting bracket connected to the second segments of the two connecting rods and located above the supporting mechanism, for performing up-and-down movement with the swinging of the connecting rods; and a bidirectional buffer component hingedly connected at one end to the mounting bracket and at the other end to the base, for providing two opposite-direction buffer forces to the up-and-down movement of the mounting bracket.

[0009] In an embodiment, the base is provided with a first guide sliding groove extending along a first direction; and the supporting mechanism is slidably mounted on the base through the first guide sliding groove, so as to adjust the supporting positions of the supporting components on the connecting rods by moving the supporting mechanism.

[0010] In an embodiment, the sidewall of the first guide sliding groove is provided with a plurality of lock holes arranged along the first direction; and the supporting mechanism is provided with a locking assembly matched with the lock holes, for locking the supporting mechanism to the base.

[0011] In an embodiment, the locking assembly comprises: a pin rod telescopically mounted on the supporting mechanism, for selectively inserting into the lock holes; and a third elastic element supported between the pin rod and the supporting mechanism by elastic force, for springing back to reset the pin rod when the pin rod is retracted into the supporting mechanism to compress the third elastic element to form elastic potential energy.

[0012] In an embodiment, the pin rod is provided with a give-way notch and a first inclined surface located in the give-way notch; and the locking assembly further comprises: a pull rod slidably mounted on the supporting mechanism and passing through the give-way notch, the pull rod being provided with a second inclined surface matched with the first inclined surface and a limiting part facing the pin rod;

[0013] The pull rod is pulled to slide on the supporting mechanism, so as to force the pin rod to retract out of the lock hole by the cooperation of the second inclined surface and the first inclined surface, until the limiting part is supported on the retracted pin rod to limit the maximum sliding stroke of the pull rod on the supporting mechanism.

[0014] In one embodiment, the supporting mechanism comprises: a sliding base slidably arranged in the first guide slot, the sliding base being provided with a second guide slot extending in a second direction, the second direction being perpendicular to the first direction and being capable of pointing to the base; a rotating shaft base mounted on the sliding base through the second guide slot, and the supporting component being rotatably mounted on the rotating shaft base.

[0015] The rotating shaft base is capable of sliding along the second guide slot to adjust the supporting height of the supporting component.

[0016] In one embodiment, the supporting mechanism further comprises: a nut member arranged at the bottom of the sliding base and provided with a threaded hole extending in the second direction; a lead screw member penetrating the threaded hole of the nut member and connected with the rotating shaft base, the lead screw member being provided with an external thread matched with the threaded hole;

[0017] The nut member and the lead screw member form a lead screw and nut pair, and rotating the lead screw member is capable of driving the rotating shaft base to move in the second guide slot.

[0018] In one embodiment, the supporting component comprises: a first rotating shaft member arranged on the rotating shaft base, two first supporting wheels rotatably mounted at two ends of the first rotating shaft member for bearing against the lower side wall of the connecting rod; a second rotating shaft member arranged on the rotating shaft base and located above the first rotating shaft member; and two second supporting wheels rotatably mounted at two ends of the second rotating shaft member and arranged in the second direction away from the first supporting wheels for pressing against the upper side wall of the connecting rod.

[0019] The first supporting wheels and the second supporting wheels jointly limit the maximum turning angle of the connecting rod with the rotating joint as the center.

[0020] In the second aspect, the embodiments of the present application provide a wooden rocking chair, which at least comprises the rocking device in the above technical solution.

[0021] Compared with the prior art, the swing device and the rocking horse rocking chair provided in the technical scheme have a transmission system composed of a rotating shaft, eccentrically arranged transfer wheels, a supporting mechanism and a connecting rod. The rotating shaft is driven to rotate by a driving mechanism, the two ends of the transfer wheels are driven to perform synchronous eccentric motion, and the connecting rod is driven to perform regular swing around the fulcrum of the supporting member. The complex transmission structure relying on multiple hinged arms is abandoned, and the coordination and stability of the movement process are significantly improved. Specifically, the first section is connected with the transfer wheels as a power arm, and the second section is connected with the rocking chair seat as a resistance arm, so that the two ends of the connecting rod always present a reverse swing relationship. The design makes the entire transmission process have a unique motion trajectory, does not need to rely on the linkage cooperation between multiple hinged points, greatly simplifies the mechanical structure, and reduces the failure points. At the same time, the mechanical interference, jamming or stress concentration phenomenon between the traditional hinged arms due to phase deviation is eliminated, the risk of structural damage such as deformation of the swing arm and breakage of the pin shaft is effectively prevented, and the durability and safety of the equipment are improved.

[0022] In summary, the swing device has compact structure, rapid response and smooth operation, and can maintain smooth fluctuation rhythm under the active swing of children or external force, significantly reduces the jerk feeling and abnormal sound, and improves the riding comfort. It is suitable for various types of rocking horse rocking chairs and similar swing type children's entertainment facilities, and has good industrial application prospect and market promotion value.

[0059] In the following, certain example embodiments are simply described. As those skilled in the art will recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. The drawings and description are therefore to be considered in an illustrative, rather than a restrictive, sense.

[0060] First Embodiment

[0061] Reference Figures 1 to 4As shown, the embodiment of the present application proposes a bidirectional buffer which can include: a sleeve component 61 arranged as a hollow structure and provided with an end opening 601; a blocking component 63 arranged on the end opening 601 to form a sliding chamber 602 between the bottom of the sleeve component 61 and the blocking component 63; a shaft component 62 slidably arranged on the blocking component 63, both ends of the shaft component 62 are provided with a first abutting portion and a second abutting portion, and the first abutting portion is located in the sliding chamber 602; a first elastic element 64 supported between the first abutting portion and the blocking component 63, and when the first abutting portion is displaced towards the blocking component 63, the first elastic element 64 is prompted to accumulate first elastic potential energy; and a second elastic element 65 supported between the second abutting portion and the blocking component 63, and when the second abutting portion is displaced towards the blocking component 63, the second elastic element 65 is prompted to accumulate second elastic potential energy. In the technical solution adopted in the present application, the sleeve component 61 can be provided with an end opening 601 at one end thereof, and the blocking component 63 is arranged on the end opening 601, so as to form a sliding chamber 602 between the bottom of the sleeve component 61 and the blocking component 63 inside the sleeve component 61, thereby the maximum displacement distance of the sliding chamber 602 can be limited by the bottom of the sleeve component 61 and the blocking component 63. The shaft component 62 is arranged in the sleeve component 61 through the blocking component 63, and the first abutting portion of the shaft component 62 is located in the sliding chamber 602, so that the first abutting portion can be prevented from moving out of the sliding chamber 602 through the end opening 601 by the blocking component 63, and the second abutting portion is located outside the sliding chamber 602, i.e. on the side of the blocking component 63 away from the sliding chamber 602, which can be understood that the shaft component 62 can be extended and retracted in the sleeve component 61. The design key of the bidirectional buffer lies in that the first elastic element 64 is elastically supported between the first abutting portion and the blocking component 63, and the second elastic element 65 is elastically supported between the second abutting portion and the blocking component 63.In use, the shaft component 62 is telescoped on the sleeve component 61 in the height direction based on the blocking component 63, when the shaft component 62 is extended out of the sleeve component 61, then the first abutting part is displaced in the sliding chamber 602 in the direction close to the blocking component 63, so that the distance between the first abutting part and the blocking component 63 is shortened to compress the first elastic element 64 to accumulate the first elastic potential energy, which can be used as the first buffer force in the opposite direction in the bidirectional buffer of the present application; on the contrary, when the shaft is retracted into the sleeve component 61, then the second abutting part is displaced in the direction close to the blocking component 63, at the same time, the first abutting part is displaced in the sliding chamber 602 in the direction away from the blocking component 63, so that the distance between the first abutting part and the blocking component 63 is increased, the first elastic element 64 is in the state of not being applied with force, while the distance between the second abutting part and the blocking component 63 is reduced to compress the second elastic element 65 to accumulate the second elastic potential energy, which can be used as the second buffer force in the opposite direction of the first buffer force in the bidirectional buffer of the present application. Thus, the bidirectional buffer of the present application can provide two opposite direction buffer forces, and the first elastic element 64 and the second elastic element 65 can not affect each other in the process of buffering. It can be used in scenes requiring two opposite directions; for example: applied to a child rocking horse, it can be explained that although the swinging direction of the rocking horse is mostly set as a circular arc swing, the swinging amplitude is in two opposite directions, the present application can be used in the rocking horse by using the bidirectional buffer, i.e. connected between the mounting bracket 5 and the base 1 in a hinged manner, so that when the swinging amplitude approaches the highest point and the lowest point, the first buffer force and the second buffer force in the opposite direction can offset the jerk feeling in the switching direction in the swinging process, which can effectively improve the stability and softness, make the swinging process more comfortable, and avoid physiological discomfort caused by obvious jerk feeling.

[0062] Further, in some embodiments, the shaft rod component 62 comprises: a rod body 621 arranged in a strip shape; a first spring seat 622 sleeved on one end of the rod body 621 and located in the sliding chamber 602, and the first spring seat 622 forms a first abutting portion on the side facing the blocking component 63; and a second spring seat 623 sleeved on the other end of the rod body 621 and located on the side of the blocking component 63 away from the sliding chamber 602, and the second spring seat 623 forms a second abutting portion on the side facing the blocking component 63. In the technical solution adopted in the present application, in order to enable the shaft rod component 62 to compress the first elastic element 64 or the second elastic element 65 to accumulate elastic potential energy during sliding, the rod body 621 is arranged in a strip shape, which is adapted to the blocking component 63, i.e., capable of sliding in the blocking component 63 along the height direction of the sleeve component 61, and the first spring seat 622 and the second spring seat 623 are respectively sleeved on the two ends of the rod body 621, the first spring seat 622 is located in the sliding chamber 602, and the second spring seat 623 is located on the side of the blocking component 63 away from the sliding chamber 602, the first spring seat 622 is used to abut against the first elastic element 64, and the second spring seat 623 is used to abut against the second elastic element 65.

[0063] Further, in some embodiments, the first elastic element 64 and the second elastic element 65 are both arranged as compression springs, the first elastic element 64 is sleeved on the rod body 621 and elastically supported between the first spring seat 622 and the blocking component 63, and the second elastic element 65 is sleeved on the rod body 621 and elastically supported between the second spring seat 623 and the blocking component 63. In the technical solution adopted in the present application, in order to enable the first elastic element 64 and the second elastic element 65 to play a more stable elastic support role, the first elastic element 64 and the second elastic element 65 can be selected as compression springs and respectively sleeved on the rod body 621 of the shaft rod component 62, so that when the first elastic element 64 is elastically supported between the first spring seat 622 and the blocking component 63, the two elastic ends of the first elastic element 64 can be aligned with the one end of the first spring seat 622 and the blocking component 63 facing the sliding chamber 602 through the limiting of the rod body 621, and when the second elastic element 65 is elastically supported between the second spring seat 623 and the blocking component 63, the two elastic ends of the second elastic element 65 can also be aligned with the one end of the second spring seat 623 and the blocking component 63 away from the sliding chamber 602 through the limiting of the rod body 621.

[0064] Further, in some embodiments, the blocking component 63 is a sleeve component with a central hole 631, and the axis of the central hole 631 coincides with the axis of the sleeve component 61; the shaft component 62 is slid through the central hole 631. In the technical solution adopted in the present application, the rod body 621 of the shaft component 62 is threaded through the central hole 631 of the blocking component 63, and since the axis of the central hole 631 coincides with the axis of the sleeve component 61, the sliding direction of the shaft component 62 is limited by the blocking component 63 to be the axial direction of the sleeve component 61, which can also be understood as the height direction of the sleeve component 61.

[0065] Further, in some embodiments, a fastener is further included; the peripheral side of the blocking component 63 is provided with a first mounting hole 632; the barrel wall of the sleeve component 61 is provided with a second mounting hole 603 corresponding to the first mounting hole 632; the fastener is threaded through the first mounting hole 632 and the second mounting hole 603 to fix the blocking component 63 in the sleeve component 61. In the technical solution adopted in the present application, the sleeve component 61 can be sleeved on the blocking component 63, and the first mounting hole 632 and the second mounting hole 603 are adjusted to be in a coincident state, and then the fastener is threaded through the first mounting hole 632 and the second mounting hole 603, so as to fix the blocking component 63 in the sleeve component 61.

[0066] Further, in some embodiments, the fastener is a pin, and is installed in the first mounting hole 632 and the second mounting hole 603 in an interference fit. In the technical solution adopted in the present application, the fastener and the first mounting hole 632 and the second mounting hole 603 can be in an interference fit, so that the fastener can be a pin with a light rod structure; when the first mounting hole 632 and the second mounting hole 603 are adjusted to be in a coincident state, the pin can be embedded in the first mounting hole 632 and the second mounting hole 603, so as to fix the blocking component 63 in the sleeve component 61.

[0067] Further, in some embodiments, the fastener is a bolt, and the first mounting hole 632 and the second mounting hole 603 are both provided with internal threads, and the fastener is installed in the first mounting hole 632 and the second mounting hole 603 in a threaded fit. In the technical solution adopted in the present application, the fastener and the first mounting hole 632 and the second mounting hole 603 can also be in a threaded fit, so that the fastener can be a bolt with external threads, and the first mounting hole 632 and the second mounting hole 603 are provided with internal threads; when the first mounting hole 632 and the second mounting hole 603 are adjusted to be in a coincident state, the bolt can be screwed into the first mounting hole 632 and the second mounting hole 603, so as to fix the blocking component 63 in the sleeve component 61.

[0068] Further, in some embodiments, the sleeve component 61 is provided with a first mounting lug 611 at one end away from the end opening 601, and the first mounting lug 611 is used to connect a first target device; the second spring seat 623 is provided with a second mounting lug 623a at one end away from the blocking component 63, and the second mounting lug 623a is used to connect a second target device. In the technical scheme adopted in the present application, the first mounting lug 611 and the second mounting lug 623a can be connected to different devices respectively, for example, the first target device and the second target device, the first target device and the second target device move relative to each other, and the first mounting lug 611 is arranged on the sleeve component 61, while the second mounting lug 623a is arranged on the second spring seat 623 in the shaft component 62. Since the sleeve component 61 and the shaft component 62 can also move relative to each other, the sleeve component 61 can move synchronously with the first target device, while the shaft component 62 moves synchronously with the second target device, so as to apply the first buffering force and the second buffering force between the first target device and the second target device.

[0069] Further, in some embodiments, the first mounting lug 611 is integrally formed with the sleeve component 61; the second mounting lug 623a is integrally formed with the second spring seat 623. In the technical scheme adopted in the present application, the first mounting lug 611 can be formed on the sleeve component 61, and the second mounting lug 623a can be formed on the second spring seat 623. The integrally formed structure not only can reduce the assembly steps, but also can avoid unnecessary shaking due to loose mounting structure. It should be noted that if the first mounting lug 611 can shake on the sleeve component 61, or the second mounting lug 623a can shake on the shaft component 62, a significant jerk feeling will be generated on the swinging device. After the integrally formed structure is selected, the problem can be avoided. In the process of daily maintenance, once the first mounting lug 611 on the sleeve component 61 and the second mounting lug 623a on the second spring seat 623 are found to be broken, a new sleeve component 61 or second spring seat 623 can be replaced. Thus, frequent adjustment and maintenance are not needed, and only replacement and maintenance are needed.

[0070] Second embodiment

[0071] Reference Figure 5 , Figure 7 and Figure 8As shown, the embodiment of the present application proposes a swinging device, which can include: a base 1; a driving mechanism 2 installed on the base 1, the driving mechanism 2 including: a rotating shaft 21 driven to rotate by the driving mechanism 2, and two transfer wheels 22 respectively eccentrically arranged on both ends of the rotating shaft 21; a supporting mechanism 3 installed on the base 1 and located on a radial side of the rotating shaft 21, both sides of the supporting mechanism 3 being provided with supporting components; and two connecting rods 4, the middle parts of the connecting rods 4 being respectively supported on the corresponding supporting components to divide the connecting rods 4 into first segments and second segments; the first segments being located between the supporting components and the transfer wheels 22, and the end parts of the first segments being rotationally connected with the transfer wheels 22 on the same side, and the second segments being located on the sides of the supporting components away from the transfer wheels 22.

[0072] Wherein, the two transfer wheels 22 are driven to synchronously eccentrically rotate by the rotating shaft 21 to drive the two connecting rods 4 to swing around the corresponding supporting components, and the swinging direction of the first segments is opposite to the swinging direction of the second segments.

[0073] Specifically, in the technical scheme adopted in the present application, the base 1 is used to be placed on a target site, and functions to carry driving function components and transmission function components required for realizing the swinging and undulating action, and to provide a stable installation foundation for the whole device. The driving mechanism 2 preferably adopts a motor and a worm gear assembly. The motor can serve as a power source of rotating mechanical energy, and the worm gear bears the function of power transmission, and can stably transmit the rotating mechanical energy of the motor output shaft to a target function component, such as the rotating shaft 21 in the embodiment of the present application. The two shaft end faces of the rotating shaft 21 are respectively eccentrically provided with adapter wheels 22, so as to ensure that when the rotating shaft 21 is driven to rotate by the driving mechanism 2, the two adapter wheels 22 can synchronously perform eccentric motion, and provide power input for the subsequent connecting rod 4 to swing. The base 1 is further provided with a supporting mechanism 3, which is located on one side of the driving mechanism 2, specifically on the radial side of the rotating shaft 21. The two sides of the supporting mechanism 3 are provided with supporting components corresponding to the two adapter wheels 22, forming a symmetrical supporting structure. The technical key point of the present application further comprises: two connecting rods 4, and the middle parts of each connecting rod 4 are respectively supported on the corresponding supporting components, so that the supporting components constitute a swinging fulcrum on the connecting rod 4. The fulcrum can divide the connecting rod 4 into two sections, wherein the first section between the supporting component and the adapter wheel 22 is a power arm, and the second section on the side of the supporting component away from the adapter wheel 22 is a resistance arm. The end of the first section is rotatably connected to the adapter wheel 22 on the same side in a sleeving manner, so as to ensure that the eccentric rotation of the adapter wheel 22 can stably transmit the force to the connecting rod 4, and further drive the connecting rod 4 to undulate and swing around the fulcrum formed by the supporting component. In the embodiment, the adapter seat 10 for connecting the rocking chair can be arranged on the second section of the connecting rod 4, and the undulating and swinging of the connecting rod 4 is directly converted into the rocking action of the rocking chair through the lever principle. This design greatly simplifies the complex transmission mechanism in the traditional rocking device, for example, the traditional structure often relies on multiple hinged swinging arms, effectively avoiding the problem of jamming or mechanical structure interference caused by the direction disorder of the swinging arm due to inertia in the rocking process. Since the connecting rod 4 of the present application is designed based on the lever principle and is limited by the supporting component, the first section and the second section of the connecting rod 4 can always swing in opposite directions around the fulcrum: when the first section rotates downward with the adapter wheel 22, the second section rotates upward after changing the direction of the force by the supporting component; conversely, when the first section rotates upward with the adapter wheel 22, the second section rotates downward. The motion law of the whole transmission process is unique and stable, which fundamentally eliminates the possibility of structural obstruction between the transmission components.

[0074] Further, referring to Figure 5 shown, in some embodiments, further comprising: a mounting bracket 5 connected to the second sections of the two connecting rods 4, located above the supporting mechanism 3, for undulating motion with the swinging of the connecting rods 4; a bidirectional buffer 6 hinged at one end to the mounting bracket 5 and at the other end to the base 1, for providing two opposite direction buffer forces to the undulating action of the mounting bracket 5.

[0075] Specifically, in the technical scheme adopted by the present application, in order to realize the configuration of the adapter 10 on the connecting rod 4, a mounting bracket 5 can be fixedly installed on the connecting rod 4, the mounting bracket 5 can include a top plate and four supporting legs formed on the bottom of the top plate, the four supporting legs can be divided into two front supporting legs and two rear supporting legs according to the extension direction of the connecting rod 4, the two front supporting legs are connected with the end of the second section in a plug-in manner, and the two rear supporting legs are detachably installed on the upper side of the first section by fasteners, so that the mounting bracket 5 can move up and down with the connecting rod 4, thereby facilitating the detachable installation of the adapter 10 on the top of the mounting bracket 5. The bidirectional buffer 6 mentioned in the first embodiment can also be installed in a hinged manner between the mounting bracket 5 and the base 1, specifically, the first mounting lug 611 is hingedly connected to the mounting bracket 5, and the second mounting lug 623a is hingedly connected to the base 1, so that when the mounting bracket 5 moves up and down driven by the connecting rod 4, the bidirectional buffer 6 can provide two opposite and reverse buffer forces to relieve the jerk feeling during the up-and-down movement, thereby significantly improving the softness. For the specific structure of the bidirectional buffer 6, please refer to the content in the first embodiment, and thus it will not be repeated here.

[0076] Further, referring to FIG. 1, Figure 6 As shown in FIG. 1, in some embodiments, the base 1 is provided with a first guide chute 101 extending in the first direction; the supporting mechanism 3 is slidably installed on the base 1 through the first guide chute 101, so as to adjust the supporting position of the supporting part on the connecting rod 4 by moving the supporting mechanism 3.

[0077] Specifically, in the technical solution adopted in this application, the first direction can be the length direction of the base 1, which is also the arrangement direction of the drive mechanism 2 and the support mechanism 3. Thus, the support mechanism 3 slides on the first guide groove 101 to move away from or closer to the drive mechanism 2. In other words, the distance between the adapter wheel 22 and the support component can be adjusted by the first guide groove 101 to change the swing amplitude of the second section on the connecting rod 4. In use, when the support mechanism 3 slides towards the drive mechanism 2 via the first guide groove 101, the distance between the adapter wheel 22 and the support component decreases, and the fulcrum formed by the support component on the connecting rod 4 also moves synchronously. This causes the first segment of the connecting rod 4 to shorten and the second segment to lengthen. When eccentrically rotated via the adapter wheel 22, the swing amplitude of the second segment is significantly increased. Conversely, when the support mechanism 3 slides away from the drive mechanism 2 via the first guide groove 101, the distance between the adapter wheel 22 and the support component increases, and the fulcrum formed by the support component on the connecting rod 4 also moves synchronously. This causes the first segment of the connecting rod 4 to lengthen and the second segment to shorten. When eccentrically rotated via the adapter wheel 22, the swing amplitude of the second segment is significantly reduced. The technical solution in this embodiment effectively improves the adjustability of the swing device, and the adjustment method is simple, requiring no significant adjustments to the equipment drive or replacement of parts, making it more convenient and faster.

[0078] Furthermore, refer to Figure 6 and Figure 10 As shown, in some embodiments, the side wall of the first guide groove 101 is provided with a plurality of lock holes 102 arranged along the first direction; the support mechanism 3 is provided with a locking component that cooperates with the lock holes 102, for locking the support mechanism 3 to the base 1.

[0079] Specifically, in the technical solution adopted in this application, in order to fix the support mechanism 3, which has completed the sliding adjustment, onto the base 1, a plurality of locking holes 102 arranged along the first direction can be opened on the side wall of the first guide groove 101, and the arrangement shape of each locking hole 102 is set as a straight line; and a locking component that can be adapted to the locking hole 102 can be provided on the support mechanism 3. In use, when the support mechanism 3 slides along the first guide groove 101 to the target position, the locking component can cooperate with the locking hole 102 to limit the support mechanism 3 onto the base 1, thereby fixing the position of the support component supported on the connecting rod 4, and determining the maximum swing amplitude of the first and second segments of the connecting rod 4 around the fulcrum. This can effectively prevent the support mechanism 3 from sliding uncontrollably in the first limiting groove, causing unnecessary trouble.

[0080] Furthermore, refer to Figure 11As shown, in some embodiments, the locking assembly comprises: a pin rod 7 telescopically mounted on the supporting mechanism 3 for alternatively inserting into the locking hole 102; a third elastic element 8 elastically supported between the pin rod 7 and the supporting mechanism 3, and compressed to form elastic potential energy when the pin rod 7 is retracted into the supporting mechanism 3, for springing back to reset the pin rod 7.

[0081] Specifically, in the technical solution adopted in the present application, the pin rod 7 can be extended into the corresponding locking hole 102 by the elastic force of the third elastic element 8, to prevent the supporting mechanism 3 from sliding in the first guide chute 101, thereby fixing the supporting mechanism 3 at the target position on the base 1. In use, when the acting force makes the locking rod retract out of the locking hole 102, the locking state of the supporting mechanism 3 on the base 1 can be contacted; at the same time, the pin rod 7 compresses the third elastic element 8 to form elastic energy storage, and when the acting force applied on the pin rod 7 disappears, the third elastic element 8 can release the elastic energy storage to drive the pin rod 7 to pop out.

[0082] Further, referring to Figure 11 and Figure 12 As shown, in some embodiments, the pin rod 7 is provided with a let-go notch 701 and a first inclined surface 702 located in the let-go notch 701; the locking assembly further comprises: a pull rod 9 slidably mounted on the supporting mechanism 3 and passing through the let-go notch 701, the pull rod 9 being provided with a second inclined surface 901 cooperating with the first inclined surface 702 and a limiting portion 902 facing the pin rod 7;

[0083] Wherein, the pull rod 9 is pulled to slide on the supporting mechanism 3, to force the pin rod 7 to retract out of the locking hole 102 by the cooperation of the second inclined surface 901 and the first inclined surface 702, until the limiting portion 902 supports on the retracted pin rod 7, to limit the maximum sliding stroke of the pull rod 9 on the supporting mechanism.

[0084] Specifically, in the technical scheme adopted in the present application, in order to facilitate the extension and retraction of the pin rod 7, a clearance gap 701 is further formed on the pin rod 7, and a first inclined surface 702 is formed in the clearance gap 701, and the pull rod 9 is vertically installed on the supporting mechanism 3 and embedded in the clearance gap 701, and the end of the pull rod 9 is formed with a second inclined surface 901 matched with the first inclined surface 702 and a limiting portion 902 corresponding to the radial side surface of the pin rod 7. When the pull rod 9 slides in the clearance gap 701 based on the supporting mechanism 3, the pull rod 9 can gradually exert a pushing force on the first inclined surface 702 through the second inclined surface 901 to facilitate the retraction of the pin rod 7, and when the pin rod 7 is fully retracted, the limiting portion 902 can abut against the pin rod 7 in the retracted state, thereby limiting the maximum sliding stroke of the pull rod 9 to limit it in the supporting mechanism 3, avoiding the disconnection of the pull rod 9 and the supporting mechanism 3, so that the pin rod 7 can be released by pulling the pull rod 9. The limiting of the supporting mechanism 3 on the base 1, and the supporting mechanism 3 can be freely slid in the first direction in the first guide slot 101 to complete the adjustment of the distance between the supporting mechanism 3 and the driving mechanism 2.

[0085] Further, referring to Figure 8 In some embodiments, the supporting mechanism 3 includes a sliding seat 31 slidably arranged in the first guide slot 101, the sliding seat 31 being provided with a second guide slot 311 extending in a second direction, the second direction being perpendicular to the first direction and being capable of pointing to the base 1; a rotating shaft seat 32 being installed on the sliding seat 31 through the second guide slot 311, and the supporting component being rotatably installed on the rotating shaft seat 32.

[0086] The rotating shaft seat 32 can slide along the second guide slot 311 to adjust the supporting height of the supporting component.

[0087] Specifically, in the technical scheme adopted in the present application, the sliding seat 31 is slidably mounted on the base 1 through the first guide sliding groove 101, and the sliding seat 31 is provided with a mounting hole corresponding to the side wall of the first guide sliding groove 101, the pin rod 7 is telescopically arranged in the mounting hole, and the third elastic element 8 is elastically supported between the bottom of the mounting hole and the pin rod 7; the sliding seat 31 is provided with a second guide sliding groove 311 extending in the second direction, which can be the height direction of the base 1 after the sliding seat 31 is mounted on the base 1, and the rotating shaft seat 32 is slidably arranged in the second guide sliding groove 311, and the supporting component is rotatably mounted on the rotating shaft seat 32, so that when the rotating shaft seat 32 slides in the second direction based on the sliding seat 31 in the second guide sliding groove 311, the interval distance between the supporting component and the base 1 can be adjusted, that is, the supporting height of the supporting component is adjusted. Thus, the position of the second segment of the connecting rod 4 in the second direction is adjusted, and it can be understood that when the rotating shaft seat 32 slides away from the base 1, the supporting height of the supporting component is increased, so that the interval distance between the second segment of the connecting rod 4 and the base 1 is gradually increased, and thus the swing position of the connecting rod 4 in the second direction is increased; on the contrary, when the rotating shaft seat 32 slides towards the base 1, the supporting height of the supporting component is reduced, so that the interval distance between the second segment of the connecting rod 4 and the base 1 is gradually reduced, and thus the swing position of the connecting rod 4 in the second direction is reduced. It should be explained that when the rotating shaft seat 32 is adjusted based on the second guide sliding groove 311 on the sliding seat 31, the swing range of the second segment of the connecting rod 4 will not be greatly changed, but the swing position of the connecting rod 4 in the second direction is adjusted, which can be taken as a reference object based on the base 1, that is, the interval distance between the swing position of the connecting rod 4 and the base 1 is increased or reduced. By adjusting the swing position of the connecting rod 4, the swing device in the present embodiment can be adapted to more use scenarios, and by adjusting the supporting height of the supporting component on the connecting rod 4, different heights of the undulating motion and different pitch angles can be provided, so that the swing mode of the swing device is more diverse.

[0088] Further, referring to Figure 9 In some embodiments, the supporting mechanism 3 further comprises: a nut member 33 arranged at the bottom of the sliding seat 31 and provided with a threaded hole extending in the second direction; a lead screw member 34 threaded in the threaded hole of the nut member 33 and connected with the rotating shaft seat 32, and the lead screw member 34 is provided with an external thread matched with the threaded hole.

[0089] The nut member 33 and the lead screw member 34 form a lead screw and nut pair, and rotating the lead screw member 34 can drive the rotating shaft seat 32 to move in the second guide sliding groove 311.

[0090] Specifically, in the technical scheme adopted by the present application, the rotation shaft base 32 can be driven to slide in the first guide sliding groove 101 of the sliding base 31 by the screw nut movement pair, so that unnecessary trouble caused by the random sliding of the rotation shaft base 32 in the sliding base 31 can be avoided. The nut member 33 can be fixedly arranged on the base 1 of the sliding base 31, and the nut member 33 has a threaded hole extending towards the second direction. The screw rod member 34 is arranged in the threaded hole of the nut member 33, and the screw rod member 34 is rotatably extended from the bottom of the sliding base 31 to the rotation shaft base 32, so that the rotation shaft base 32 can be locked at a target position in the second guide sliding groove 311 by the cooperation of the screw rod member 34 and the nut member 33. When it is necessary to adjust the position of the rotation shaft base 32, the screw rod member 34 is rotated to displace the rotation shaft base 32 in the second guide sliding groove 311 by the threaded cooperation.

[0091] Further, referring to FIG. 6, in some embodiments, the supporting member includes a first rotation shaft member 35 arranged on the rotation shaft base 32, two first supporting wheels 36 rotatably mounted at two ends of the first rotation shaft member 35 for bearing against the lower side wall of the connecting rod 4, a second rotation shaft member 37 arranged on the rotation shaft base 32 above the first rotation shaft member 35, and two second supporting wheels 38 rotatably mounted at two ends of the second rotation shaft member 37 and spaced apart from the first supporting wheels 36 along the second direction for pressing against the upper side wall of the connecting rod 4. Figure 8

[0092] In the above technical scheme, the first supporting wheels 36 and the second supporting wheels 38 jointly limit the maximum turning angle of the connecting rod 4 with the turning wheel 22 as the center of rotation.

[0093] ​Specifically, in the technical scheme adopted in the present application, the first rotating shaft member 35 is arranged in a penetrating manner on the rotating shaft seat 32, and the axial direction of the first rotating shaft member 35 is parallel to the rotating shaft direction of the rotating shaft 21, and two first supporting wheels 36 are rotatably arranged at the two ends of the first rotating shaft member 35, and the two first supporting wheels 36 are exposed on the two sides of the sliding seat 31 and the rotating shaft seat 32, so as to be capable of being supported on the side wall of the connecting rod 4, thereby forming a fulcrum on the connecting rod 4, and when the connecting rod 4 is driven to move up and down by the eccentric rotation of the adapter wheel 22, the first supporting wheels 36 can change the swing direction of the first section and the second section. In further embodiments, a second rotating shaft member 37 above the first rotating shaft member 35 can also be arranged on the rotating shaft seat 32, and the axial direction of the second rotating shaft member 37 is also parallel to the axial direction of the rotating shaft 21, and two second supporting wheels 38 are rotatably arranged at the two ends of the second rotating shaft member 37, and the two second supporting wheels 38 are located directly above the first supporting wheels 36, so that the first supporting wheels 36 and the second supporting wheels 38 can limit the maximum turning angle of the connecting rod 4 with the adapter wheel 22 as the rotating center, and when the connecting rod 4 is turned towards the second supporting wheels 38, the second supporting wheels 38 can be pressed on the upper side wall of the connecting rod 4, so as to avoid unnecessary risks caused by the arbitrary turning of the connecting rod 4. It should be noted that the first supporting wheels 36 and the second supporting wheels 38 in contact with the connecting rod 4 are rotatable, so that the rolling friction between the connecting rod 4 and the first supporting wheels 36 and the second supporting wheels 38 can be generated when the connecting rod 4 moves up and down, thereby reducing the wear of the connecting rod 4 and prolonging the service life.
