Description

Technical Field

[0001] This invention relates to the field of furniture-related technology, and in particular to a flexible percussion core. Background Technology

[0002] In current related technologies, the driving method of the rhythmic core of rhythmic furniture is based on the crank connection to realize the reciprocating linear motion of the rhythmic frame relative to the fixed frame, thereby realizing the core rhythmic function of the rhythmic core.

[0003] However, because the relevant technology uses crank drive to directly connect to the rhythm frame, the transmission characteristics result in a strong mechanical feel, excessively fast reversal speed, and instantaneous switching action when the rhythm frame reverses direction. This not only causes abrupt jerking and discomfort for the user, but more seriously, this instantaneous directional change generates a violent impact that acts directly on the rhythm frame, leading to severe mechanical vibration and noise, and significantly accelerating the wear of components. Summary of the Invention

[0004] This invention provides a flexible rhythmic core to solve the problems in related technologies where the user experience is poor due to the instantaneous reversal of the rhythmic frame during front-to-back reversal, and it is also prone to causing severe mechanical vibration and noise, and significantly aggravating the wear of components.

[0005] This invention provides a flexible percussion core, comprising: Fixture; The rhythm frame can reciprocate back and forth relative to the fixed frame; The drive assembly is located on the fixed frame; The transmission assembly includes a first transmission component and a second transmission component. The first transmission component is eccentrically connected to the output end of the drive assembly, and the second transmission component is connected to the rhythm frame. The flexible reversing structure includes an elastic transmission component, wherein the first transmission component and the second transmission component are connected by the elastic transmission component. The motion transmission path between the first transmission component and the second transmission component is non-linearly arranged through the elastic transmission member. During the change of the motion direction of the rhythm frame, the elastic transmission member undergoes elastic deformation, so that the change of the motion direction of the rhythm frame is a continuous transition.

[0006] According to a flexible actuator provided by the present invention, the two ends of the elastic transmission member are in contact or connected with the force-bearing surfaces of the first transmission member and the second transmission member, respectively, so as to transmit thrust or pull between the first transmission member and the second transmission member; The second transmission component is integrally formed with the rhythm frame or is fixedly connected separately.

[0007] According to a flexible actuator provided by the present invention, a preset gap is provided between the first transmission member and the second transmission member, and the projection of at least a portion of the elastic transmission member on the horizontal plane is located within the orthographic projection of the preset gap on the horizontal plane.

[0008] According to a flexible actuator provided by the present invention, on the orthographic projection on a horizontal plane, the projection area of ​​at least one of the first transmission member and the second transmission member is independently set from the projection area of ​​the elastic transmission member. Alternatively, on a horizontal plane, the projection area of ​​at least one of the first and second transmission members and the projection area of ​​the elastic transmission member at least partially overlap.

[0009] According to the present invention, a flexible actuator core is provided in which the elastic deformation of the elastic transmission member is at least one of compression deformation, tensile deformation or bending deformation.

[0010] According to the present invention, a flexible pulsator core is provided, wherein the elastic transmission component has a U-shaped structure, the elastic transmission component includes an arc segment, a first vertical segment and a second vertical segment, the first vertical segment and the second vertical segment are spaced apart and arranged in parallel, one end of the arc segment is connected to the first vertical segment and the other end is connected to the second vertical segment; The first transmission component and the second transmission component are spaced apart along the reciprocating motion direction. The first transmission component is connected to the first vertical segment, and the second transmission component is connected to the second vertical segment.

[0011] According to a flexible actuator provided by the present invention, the elastic transmission member has an L-shaped structure and includes a vertical part and a horizontal part connected to the vertical part; The first transmission component and the second transmission component are stacked vertically and their orthographic projections on the horizontal plane are independent of each other. One of the first transmission component and the second transmission component is connected to the vertical part, and the other is connected to the horizontal part.

[0012] According to the present invention, a flexible pulsator core is provided, wherein the elastic transmission member has an I-shaped structure, and the first transmission member and the second transmission member are stacked one on top of the other and at least a portion of their orthogonal projections on the horizontal plane coincide. The first transmission member and the second transmission member have a gap between their opposite sides, one of the first transmission member and the second transmission member is connected to the upper end of the elastic transmission member, and the other is connected to the lower end of the elastic transmission member.

[0013] According to a flexible pulse core provided by the present invention, a first reinforcing plate is provided on one side of the first transmission member, and a second reinforcing plate is provided on one side of the second transmission member; The lengths of the first transmission component and the second transmission component are consistent with the forward and backward movement direction of the rhythm frame. The first reinforcing plate extends along the first transmission component, and the second reinforcing plate extends along the second transmission component.

[0014] According to the present invention, a flexible actuator core is provided, wherein the driving component comprises: A direct drive motor is mounted on the fixed frame, and the direct drive motor has a rotating shaft; The bearing housing is provided on the fixed frame; A crankshaft is rotatably mounted on the bearing housing, and one end of the crankshaft is connected to the rotating shaft via a coupling. The first transmission component is eccentrically connected to the crankshaft.

[0015] According to a flexible actuator core provided by the present invention, the driving assembly further includes: A transmission sleeve is rotatably mounted on the crankshaft, and the rotation center line of the transmission sleeve is eccentrically set with respect to the rotation center line of the crankshaft. The transmission sleeve is fixedly connected to the first transmission component.

[0016] According to the present invention, a flexible actuator core is provided, wherein the transmission sleeve comprises: Two sets of transmission units are spaced apart and rotatably sleeved on the crankshaft. One end of each set of transmission units is fixedly connected to the first transmission component, and a linkage plate connecting the two sets of transmission units is provided between the other ends of the two sets of transmission units.

[0017] The flexible rhythmic actuator provided by this invention drives a first transmission component to move, and a second transmission component to move through a flexible reversing structure, causing the rhythmic frame to reciprocate back and forth relative to a fixed frame. For example, when the first transmission component moves forward, it pushes the second transmission component forward through an elastic transmission member. When switching from front to back, the elastic transmission member continues to transmit thrust gently, driving the second transmission component to move in the opposite direction.

[0018] Compared to the instantaneous direction switching of traditional crank transmission structures, this invention introduces an elastic transmission component during transmission, transforming the reversal into a gradual process with time and duration. This results in a slight blunting, less abrupt rebound, absorption of high-frequency vibrations, and smoother directional changes without any mechanical knocking sensation. Simultaneously, the elastic transmission component absorbs the inflection point impact at the peak and the speed spike during the acceleration phase of crank engagement, which greatly enhances the experience of relaxation, sleep aid, and anxiety relief. Overall, users can directly feel a gentle and elastic rhythm.

[0019] In addition, the elastic transmission components can absorb the steering impact and mechanical noise of the crank drive, making the rhythmic sound of the motor core lower and closer to the texture of the hydraulic system, thus making it more suitable for high-end product applications.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0033] The following is combined with Figure 1 - Figure 10 Describe the flexible percussion core of the present invention.

[0034] Understandably, referring to Figure 1 , Figure 3 , Figure 5 and Figure 8 In some examples of the present invention, the flexible rhythmic core includes a fixing frame 100, a rhythmic frame 200, a drive assembly 300, a transmission assembly, and a flexible reversing structure.

[0035] The rhythm frame 200 can reciprocate back and forth relative to the fixed frame 100; the drive assembly 300 is disposed on the fixed frame 100; the transmission assembly includes a first transmission component 410 and a second transmission component 420, the first transmission component 410 is eccentrically connected to the output end of the drive assembly 300, and the second transmission component 420 is connected to the rhythm frame 200 in a transmission manner. The flexible reversing structure includes an elastic transmission element 500, and the first transmission component 410 and the second transmission component 420 are connected by the elastic transmission element 500. The motion transmission path between the first transmission component 410 and the second transmission component 420 is non-linearly set through the elastic transmission component 500. During the change of the motion direction of the rhythm frame 200, the elastic transmission component 500 undergoes elastic deformation, so that the change of the motion direction of the rhythm frame 200 is a continuous transition.

[0036] The flexible rhythmic actuator provided by this invention drives the first transmission member 410 to move via the drive assembly 300, and drives the second transmission member 420 to move via a flexible reversing structure. The rhythmic frame 200 reciprocates back and forth relative to the fixed frame 100. For example, when the first transmission member 410 moves forward, it pushes the second transmission member 420 forward via the elastic transmission member 500. When switching from front to back, the elastic transmission member 500 continues to transmit thrust continuously and gently, driving the second transmission member 420 to move in the opposite direction.

[0037] Compared to the instantaneous direction switching of traditional crank transmission structures, this invention introduces an elastic transmission component 500 during transmission, transforming the reversal into a gradual process with time and duration. This results in a slight blunting, less sudden rebound, absorption of high-frequency vibrations, and smoother directional changes without any mechanical knocking sensation. Simultaneously, the elastic transmission component 500 absorbs the inflection point impact at the peak and the speed spike during the acceleration phase of crank engagement, which greatly enhances the experience of soothing, aiding sleep, and relieving anxiety. Overall, users can directly feel a gentle and elastic rhythm.

[0038] In addition, the elastic transmission component 500 can absorb the steering impact and mechanical noise of the crank drive, making the rhythm sound of the motor core lower and closer to the texture of the hydraulic system, thus making it more suitable for high-end product applications.

[0039] It should be emphasized that the motion transmission path between the first transmission component 410 and the second transmission component 420 is set in a non-linear manner through the elastic transmission component 500, such as an inclined, broken line or a curve arrangement. The core is to utilize the lateral flexibility and displacement conversion effect of the elastic transmission component 500 when it is under tension / compression to construct an intelligent force transmission chain of linear drive-curved buffer-target following.

[0040] On the one hand, the non-linear path forces the elastic transmission component 500 to undergo controllable bending / torsional deformation before transmitting force. This "pre-deformation" process naturally absorbs sudden loads (such as sudden start / stop and reversing impacts) in the movement of the first transmission component 410, transforming rigid impacts into flexible stress release. On the other hand, the angle or curvature design of the path can amplify the micro-displacement response of the elastic transmission component 500. The small linear motion of the first transmission component 410, after being amplified by the deformation of the non-linear elastic transmission component 500, can drive the second transmission component 420 to follow more smoothly, avoiding "jamming" or "overshooting" caused by direct rigid connection. At the same time, the non-linear arrangement also provides a certain degree of angle self-adaptation capability, which can compensate for the installation deviation or centering error between the first transmission component 410 and the second transmission component 420, ensuring that the force transmission always proceeds along the optimal force surface.

[0041] Ultimately, it achieves a triple effect of impact attenuation, displacement softening, and deviation compensation, preserving the effectiveness of power transmission while significantly improving the stability and lifespan of the beater core. It should also be emphasized that the aforementioned elastic transmission component 500 not only makes the reversal smooth, but also, during the eccentric transmission process of the drive assembly 300, the first transmission component 410 swings up and down while moving back and forth. Therefore, during the power transmission process from the first transmission component 410 to the second transmission component 420, the elastic transmission component 500 adapts to the up and down swing of the first transmission component 410, can absorb and buffer the up and down swing of the first transmission component 410, making the transmission smoother, which is beneficial to reducing noise. Moreover, it has a simple structure and low manufacturing cost.

[0042] Understandably, referring to Figure 1 , Figure 3 , Figure 5 and Figure 8 In some examples of the present invention, a connecting structure 600 is provided between the fixing frame 100 and the rhythm frame 200 to connect the two.

[0043] In this embodiment, the connection structure 600 can be arranged in a hanging or supporting manner to connect the fixed frame 100 and the rhythm frame 200.

[0044] In this embodiment, the arrangement of the connecting structure 600 is described as a hanging arrangement.

[0045] It should be noted that two sets of connecting structures 600 are provided between the front end of the fixed frame 100 and the front end of the rhythm frame 200, and two sets of connecting structures 600 are provided between the rear end of the fixed frame 100 and the rear end of the rhythm frame 200, which enhances the overall integrity and stability of the structure. The two connecting structures 600 share the load, effectively suppressing stress concentration and structural torsion that may occur at a single connection point, thereby improving the smoothness and reliability of equipment operation.

[0046] It should also be noted that, in this embodiment, since the fixed frame 100 and the rhythm frame 200 move relative to each other in the spatial direction, and the rhythm frame 200 is arranged to cover the fixed frame 100, the connecting structure 600 is arranged vertically, with the upper end of the connecting structure 600 engaging with the upper end of the fixed frame 100 and the lower end of the connecting structure 600 engaging with the lower end of the rhythm frame 200; of course, the connecting structure 600 can also be arranged horizontally. When the relative movement direction of the fixed frame 100 and the rhythm frame 200 switches to the up-down direction, the connecting structure 600 can be arranged horizontally, which is not limited here.

[0047] It is understood that in this embodiment, the connecting structure 600 is a swing member, one end of which is rotatably connected to the fixed frame 100, and the other end is rotatably connected to the rhythm frame 200; By designing the connecting structure 600 as a swinging component, the reciprocating rhythm frame 200 can be effectively guided, and the relative positions of the fixed frame 100 and the rhythm frame 200 in the vertical direction can be limited. After assembly, the end of the swinging component can rotate relative to the fixed frame 100 and the rhythm frame 200, which can accommodate the structural accuracy errors of the fixed frame 100 or the rhythm frame 200. This helps to reduce the mechanical stress between the end of the swinging component and the fixed frame 100 and the rhythm frame 200, improves reliability, and extends service life.

[0048] Specifically, in this embodiment, both the rhythm frame 200 and the fixed frame 100 are provided with bearing mounting seats, connecting columns, and positioning columns. The bearing mounting seats are provided with mounting channels. The connecting columns are rotatably mounted in the mounting channels through bearings. A clamping space is formed between the connecting columns and the positioning columns to clamp the end of the swinging component. The connecting columns, positioning columns, and swinging components are sequentially inserted through connecting bolts and threadedly connected to connecting nuts, thereby fixing the relative positions of the connecting columns, positioning columns, and swinging components, providing support and guidance for the swinging component, reducing friction and wear, and ensuring smooth rotation of the swinging component.

[0049] Of course, in some other examples, the connecting structure 600 is a spring sheet, one end of which is fixedly connected to the fixing frame 100 and the other end is fixedly connected to the rhythm frame 200; With the above configuration, when the rhythm frame 200 swings, it forces the spring to bend. The spring, like a flat spring, generates a strong restoring force when bent, attempting to return to its original shape. This restoring force always points towards the equilibrium position (i.e., the center position of the fixed frame 100). This structure ensures that the swinging of the rhythm frame 200 is a regular reciprocating motion around a defined equilibrium point, rather than random swaying. It provides the core power and guidance for the rhythm of the entire rhythmic core.

[0050] It is understood that in the above embodiments, the two ends of the spring are directly fixed to the fixing frame 100 and the rhythm frame 200 by means of pins, bolts, etc., which makes disassembly convenient and easy to maintain and replace the spring.

[0051] Understandably, referring to Figure 2 , Figure 4 , Figure 6 , Figure 7 and Figure 9 In some examples of the present invention, the two ends of the elastic transmission member 500 are in contact with or connected to the force-bearing surfaces of the first transmission member 410 and the second transmission member 420, respectively, so as to transmit thrust or pull between the first transmission member 410 and the second transmission member 420.

[0052] By directly contacting or connecting the two ends of the elastic transmission component 500 with the force-bearing surfaces of the first transmission component 410 and the second transmission component 420, a linkage mechanism that combines efficient force transmission and intelligent buffering is constructed. This mechanism reliably transmits both forward thrust and reverse pull, ensuring the integrity of power output. Furthermore, leveraging the deformation characteristics of the elastic transmission component 500, it automatically absorbs impacts and compensates for displacement errors when the motion states of the two components switch or when there are assembly / load deviations, transforming rigid collisions into a flexible, continuous force application process. This not only significantly reduces transmission noise and component wear, improving operational smoothness and durability, but also achieves a smooth transition during directional changes.

[0053] It should be noted that, in some examples of the present invention, the second transmission component 420 is integrally formed with the rhythm frame 200 or is fixedly connected separately.

[0054] It can be understood that the second transmission component 420 and the rhythm frame 200 are integrally formed, with seamless structural connection, high strength, good stability, precise transmission and convenient assembly.

[0055] The second transmission component 420 is fixed separately to the rhythm frame 200 by bolts / welding, allowing for individual part replacement, convenient maintenance, and flexible processing and design.

[0056] In some examples of the present invention, a predetermined gap exists between the first transmission member 410 and the second transmission member 420, and the projection of at least a portion of the elastic transmission member 500 onto the horizontal plane lies within the orthographic projection of the predetermined gap onto the horizontal plane. By reserving a predetermined gap between the two transmission members and placing the horizontal projection of the elastic transmission member 500 within this gap, dedicated arrangement space can be provided for the elastic transmission member 500 during flexible reversing, achieving smooth power transmission across the gap.

[0057] In some examples of the present invention, on the orthographic projection on the horizontal plane, the projection area of ​​at least one of the first transmission member 410 and the second transmission member 420 is set independently from the projection area of ​​the elastic transmission member 500.

[0058] The above can be understood as referring to Figure 2 and Figure 4 The projection area of ​​the first transmission component 410 does not overlap with the projection area of ​​the elastic transmission component 500, i.e., they are independent; refer to Figure 2 , Figure 4 and Figure 9 The projection area of ​​the second transmission component 420 does not overlap with the projection area of ​​the elastic transmission component 500, i.e., they are independent; or, referring to... Figure 2 and Figure 9 The projection areas of the first transmission component 410 and the second transmission component 420 do not overlap with the projection area of ​​the elastic transmission component 500, i.e., they are independent.

[0059] By adopting the above structure, at least one of the first transmission component 410 and the second transmission component 420 is independently set in the projection area of ​​the elastic transmission component 500 on the horizontal plane. This allows for flexible reversing while the first transmission component 410 and the second transmission component 420 are rigid transmission components compared to the elastic transmission component 500. The rigid transmission component and the elastic transmission component 500 are effectively separated in layout. This utilizes the compliance characteristics of the elastic transmission component 500 to absorb impact, compensate for installation errors, and achieve smooth reversing. Furthermore, the independent projection avoids spatial interference and vibration coupling between the two, thereby improving the smoothness of the reversing process and the reliability of the system. It also facilitates the separate optimization of the layout, assembly, maintenance, and protection design of the elastic transmission unit 341 and the rigid transmission unit 341. Ultimately, while maintaining the advantages of flexible reversing, a clearer spatial structure, higher operational stability, and more convenient engineering implementation are achieved.

[0060] By misaligning the horizontal projection, a clear partitioning of the transmission layout is achieved, thereby improving interference resistance, assembly and maintenance, space utilization, and operational reliability.

[0061] Of course, in some other examples, refer to Figure 4 and Figure 7 On the orthographic projection onto the horizontal plane, the projection area of ​​at least one of the first transmission member 410 and the second transmission member 420 at least partially overlaps with the projection area of ​​the elastic transmission member 500.

[0062] On the horizontal plane, at least one of the first transmission component 410 and the second transmission component 420 overlaps at least partially with the projection area of ​​the elastic transmission component 500. This allows the rigid transmission component and the elastic transmission component 500 to form a direct coupling zone in spatial layout during the flexible reversing process. The compliant characteristics of the elastic transmission component 500 absorb the reversing impact, compensate for axial deviation, and smoothly transmit power. At the same time, the overlapping projection shortens the force flow path and reduces the axial and radial dimensions of the reversing mechanism, making the structure more compact and the dynamic response more direct. This arrangement also enhances the phase coordination and synchronization between multiple components during the reversing process, reduces additional friction and vibration caused by misalignment, and thus improves the space utilization efficiency, transmission continuity, and overall operational reliability of the system while leveraging the advantages of flexible reversing vibration reduction, correction, and smooth transition.

[0063] Understandably, referring to Figure 2 , Figure 4 , Figure 6 , Figure 7 and Figure 9 In some examples of the present invention, the elastic deformation of the elastic transmission member 500 is at least one of compression deformation, tensile deformation or bending deformation.

[0064] With the above configuration, when the elastic transmission component 500 needs to switch the power direction from forward to backward, the compression, tension or bending deformation (at least one) that occurs can gradually absorb and release kinetic energy during the reversal process through the reversible elastic deformation characteristics. The compression deformation offsets the instantaneous reverse impact with axial buffering, the tension deformation delays the sudden change of force through longitudinal deformation, and the bending deformation guides the smooth transition of the power direction with curvature change. Through at least one of the above, the jerky feeling of rigid reversal is avoided. By utilizing the gradualness of deformation and the restoring force, the power output changes from forward to reverse in a continuous and gentle gradient, ultimately achieving a smooth reversal effect with no impact and low vibration from forward to backward movement.

[0065] Specifically, refer to Figure 1 and Figure 2 In this embodiment, the elastic transmission member 500 has a U-shaped structure. The elastic transmission member 500 includes an arc segment 511, a first vertical segment 512 and a second vertical segment 513. The first vertical segment 512 and the second vertical segment 513 are spaced apart and arranged in parallel. One end of the arc segment 511 is connected to the first vertical segment 512 and the other end is connected to the second vertical segment 513. The first transmission component 410 and the second transmission component 420 are arranged at intervals along the reciprocating motion direction. The first transmission component 410 is connected to the first vertical section 512, and the second transmission component 420 is connected to the second vertical section 513.

[0066] Based on the above, in the U-shaped elastic transmission component 500, the two ends of the arc segment 511 are respectively connected to the first vertical segment 512 and the second vertical segment 513 that are spaced apart and parallel, while the first transmission component 410 and the second transmission component 420, which are spaced apart along the reciprocating motion direction, are respectively connected to the two vertical segments.

[0067] When the direction of motion needs to be switched from forward to backward (or in the opposite direction), the U-shaped elastic transmission component 500 can flexibly adapt to the changes in the front and back positions of the two transmission components through the bending deformation of the arc segment 511. At the same time, the first vertical segment 512 and the second vertical segment 513 generate controllable tensile or compressive deformations respectively with the reciprocating motion of the transmission components. The three work together to guide the direction transition with the gradual change of curvature of the arc segment 511 and buffer the instantaneous impact force with the axial deformation of the vertical segment. By utilizing the continuity and reversibility of elastic deformation, the reverse process of power output is transformed into a smooth transition of gradient change, effectively eliminating the jolt and impact of rigid reversal. Finally, a smooth reversal effect with no sudden changes and low vibration is achieved in the forward and backward reciprocating motion.

[0068] Specifically, refer to Figure 3 and Figure 4 In some examples, the elastic transmission member 500 has an L-shaped structure, and the elastic transmission member 500 includes a vertical part 521 and a horizontal part 522 connected to the vertical part 521. The first transmission component 410 and the second transmission component 420 are stacked one on top of the other and their orthographic projections on the horizontal plane are independent of each other. The first transmission component 410 is connected to the vertical part 521 and the second transmission component 420 is connected to the horizontal part 522.

[0069] Using the above structure, when the direction of motion needs to be switched from forward to backward, the L-shaped right-angle bending structure can achieve a smooth and gentle reversal effect by the coordinated deformation of the vertical part 521 and the horizontal part 522. The vertical part 521 undergoes tensile or compressive deformation as the connected first transmission component 410 moves forward and backward to buffer the axial impact. The horizontal part 522 adapts to the independent projection position change of the stacked transmission components through lateral deformation. The two guide the reversal of the power direction with a flexible transition at the bend. By utilizing the complementary and gradual elastic deformation characteristics of the two orthogonal directions in the right-angle structure, the originally instantaneous reverse driving force is decomposed into a continuous buffering process along the vertical and horizontal directions, effectively eliminating the jerky feeling and impact load of rigid reversal, and finally achieving a smooth and gentle reversal effect from forward to backward motion.

[0070] Of course, in some other examples, the first transmission member 410 is connected to the horizontal part 522, and the second transmission member 420 is connected to the vertical part 521.

[0071] Specifically, refer to Figures 5 to 7In some examples, the elastic transmission member 500 has an I-shaped structure, and the first transmission member 410 and the second transmission member 420 are stacked one on top of the other and at least part of their orthographic projections on the horizontal plane coincide. The first transmission member 410 and the second transmission member 420 have a gap between their opposite sides. One of the first transmission member 410 and the second transmission member 420 is connected to the upper end of the elastic transmission member 500, and the other is connected to the lower end of the elastic transmission member 500.

[0072] With the above configuration, when the direction of motion needs to be switched from forward to backward, the deflection deformation of the I-shaped structure will act synchronously on the first transmission component 410 and the first transmission component 410 connected above and below. Since the projections of the two overlap and the side spacing limits the lateral offset range, the deflection deformation of the I-shaped structure can gradually transmit the reverse power through the elongation or shortening of the elastic transmission component 500, and can also buffer the instantaneous impact force with uniformly distributed axial stiffness at the moment of reversal. At the same time, the structural features of the overlapping projections make the reverse motion trajectories of the first transmission component 410 and the first transmission component 410 highly consistent, avoiding jamming or sudden changes caused by misalignment. By utilizing the linearity and continuity of the axial deformation of the I-shaped structure, the power switching from forward to backward is transformed into a smooth and gradual process along the axial direction, effectively eliminating the jolts and vibrations of rigid reversal, and finally achieving a smooth and stable reversal effect when the upper and lower stacked transmission components reverse direction.

[0073] Of course, refer to Figure 8 and Figure 9 In some other examples, the elastic transmission member 500 is a cylindrical spring member, the first transmission member 410 is connected to the second transmission member 420 through the cylindrical spring member, and the length direction of the cylindrical spring member is consistent with the transmission direction of the first transmission member 410.

[0074] When the direction of motion needs to be switched from forward to backward, the cylindrical spring can undergo controllable tensile or compressive deformation in the transmission direction. When moving forward, the cylindrical spring is in a pre-compressed or pre-stretched state, storing elastic potential energy. At the moment of reversal, the reverse driving force causes the cylindrical spring to gradually deform in the reverse direction along the transmission direction, transforming the original instantaneous direction change into a gradual process of continuous change in the length of the cylindrical spring. Utilizing the high elastic restoring force and linear buffering characteristics of the spring's axial deformation, the reverse kinetic energy is gradually absorbed and released, avoiding the impact of rigid contact and ensuring a smooth connection of power in both directions, thus achieving a smooth and gentle reversal effect from forward to backward movement.

[0075] More importantly, the cylindrical spring component, with its compact cylindrical structure and axial arrangement, replaces the design of multiple components, complex linkages, or heavy brackets in traditional transmission and support structures. This significantly simplifies the overall layout and avoids the cumbersome problems caused by abnormally complex structures. It not only reduces the number of parts and assembly steps but also lowers the requirements for mold development and processing precision, fundamentally reducing unnecessary manufacturing costs and assembly difficulties. It achieves excellent smooth reversing performance while also taking into account lightweight and economy.

[0076] Specifically, refer to Figure 8 and Figure 9 Based on the above example, the flexible transmission structure also includes a first connector 710 and a second connector 720, wherein the first connector 710 is fixedly connected to the first transmission member 410; and the second connector 720 is fixedly connected to the second transmission member 420. The first connector 710 and the second connector 720 are spaced apart, and one end of the cylindrical spring is connected to the first connector 710 and the other end is connected to the second connector 720.

[0077] With the above structure, the first connecting member 710 and the second connecting member 720 are spaced apart and connected by a cylindrical spring, so that an elastic buffer space is formed between the first transmission member 410 and the second transmission member 420 during the reversing process. The space provides the necessary stroke for the spring deformation, which not only avoids rigid direct collision, but also gradually stores and releases energy through the cylindrical spring, which transforms the instantaneous impact into a smooth force transmission, significantly softening the reversing action. At the same time, the space, together with the adjustable preload of the cylindrical spring, can adaptively compensate for the transmission phase difference, further optimizing the smoothness and stability of the reversing.

[0078] More specifically, in some examples, both the first connector 710 and the second connector 720 have fixed connection holes, one end of the cylindrical spring is inserted through and fixed to the fixed connection hole of the first connector 710, and the other end of the cylindrical spring is inserted through and fixed to the second connector 720 and the fixed connection hole.

[0079] This can be understood as follows: each end of the cylindrical spring has a corresponding fixing hole for the connector. The cylindrical spring can be fixed to the connector by welding, which avoids the risk of loosening or falling off under vibration or impact. Welding also strengthens the end strength, extends fatigue life, simplifies assembly and makes the structure more compact, and does not affect the extension and contraction freedom of the cylindrical spring. It ensures that it can still effectively absorb the reversing impact through axial deformation, thereby ensuring the reliability and durability of the connection while maintaining the elastic buffer function required for smooth reversing.

[0080] Of course, in other examples, additional fasteners can be used to secure the cylindrical spring to the connector, which is not limited here.

[0081] Specifically, refer to Figure 8 and Figure 9 In this embodiment, both the first connector 710 and the second connector 720 are plate structures.

[0082] With the above configuration, when the first connector 710 and the second connector 720 are set as plate structures, the plate structure has high planar stiffness and bending resistance, which can provide a stable support surface for the cylindrical spring component. This makes the spring more evenly stressed during the extension and contraction process, less prone to lateral swaying or instability, thereby ensuring the stability of the direction and magnitude of the buffer force and improving the consistency of smooth reversal. At the same time, it is easy to process regular fixed connection holes on the plate, which facilitates the spring insertion and welding positioning, improving assembly accuracy and efficiency. The plate can also serve as an extension surface for force transmission, more effectively transmitting the buffering effect of the spring to the corresponding transmission component and reducing local stress concentration.

[0083] In addition, in other examples, the plate structure can also integrate other functions (such as installing sensors, reinforcing ribs, or connecting with other components) to enhance modularity and structural integrity, improve reliability while ensuring lightweight, and further optimize the smoothness and durability of the commutation process.

[0084] Of course, in other examples, the first connector 710 and the second connector 720 can also be rod-shaped structures.

[0085] Reference Figure 8 and Figure 9 In this embodiment, the projection of the first connector 710 along the front-back direction is the first projection, the projection of the second connector 720 along the front-back direction is the second projection, and the projection of the cylindrical spring along the front-back direction is the third projection. In the static state, the first projection coincides with the second projection, and both the first and second projections are located in the middle of the third projection.

[0086] The projections of the first connector 710 and the second connector 720 in the front-to-back direction coincide, that is, they are aligned on the plane. The physical distance between them, combined with the length of the cylindrical spring, provides sufficient axial extension and contraction stroke for the cylindrical spring. When reversing, the cylindrical spring can fully deform and absorb energy, avoiding hard jamming or insufficient buffering.

[0087] The projection of the cylindrical spring component covers the projection of the two connecting components and is centered. This can be understood as the axis of the cylindrical spring component being basically coaxial with the connecting force line of the two units. The force generated by the reversing impact can be evenly transmitted along the center of the spring, reducing lateral force and torsional effect, making the buffering process more stable and without off-center load.

[0088] Therefore, based on the above spatial relationship, it not only ensures the smooth relative displacement of the two units when the cylindrical spring extends and retracts, but also makes the energy absorption and release more linear through symmetrical force, and the change of commutation acceleration is more gradual, which significantly improves the smoothness and gentleness of the motion.

[0089] Of course, it should also be noted that, referring to Figure 8 and Figure 9 In this embodiment, a first spacer 810 is provided between the first transmission member 410 and the first connecting member 710. The first spacer 810 is configured to provide a first preset distance between the outer side wall of the cylindrical spring member and the adjacent side wall of the first transmission member 410. A second spacer 820 is provided between the second transmission member 420 and the second connecting member 720. The second spacer 820 is configured to provide a second preset distance between the outer wall of the cylindrical spring member and the adjacent side wall of the second transmission member 420.

[0090] A first preset distance and a second preset distance are reserved between the outer wall of the cylindrical spring and the adjacent side wall of the corresponding transmission component to form an independent buffer space for the extension and retraction of the cylindrical spring. On the one hand, this avoids interference between the cylindrical spring and the side wall of the transmission component when the cylindrical spring deforms, ensuring the freedom and stroke integrity of the axial extension and retraction of the cylindrical spring and providing sufficient deformation margin for smooth reversing. On the other hand, the isolation of the preset distance prevents friction or collision noise between the cylindrical spring and the transmission component during the extension and retraction process, while weakening the rigid coupling between the two, making the elastic buffering effect of the spring more pure, transmitting energy absorption only through axial force, rather than being interfered with by lateral constraints, further optimizing the absorption efficiency and smoothness of reversing impact, and strengthening the precise spatial adaptation and functional reliability of the spacing setting.

[0091] It should be noted that in this embodiment, the first spacer 810 and the second spacer 820 are hollow tubular columns. Of course, in other examples, the first spacer 810 and the second spacer 820 can also be plates or blocks, which are not limited here.

[0092] More specifically, in this embodiment, the first transmission member 410 and the second transmission member 420 are arranged at intervals along the reciprocating motion direction. The first transmission component 410 has a first reinforcing plate 411 on one side, and the second transmission component 420 has a second reinforcing plate 421 on one side. The lengths of the first transmission component 410 and the second transmission component 420 are consistent with the forward and backward movement direction of the rhythm frame 200. The first reinforcing plate 411 extends along the first transmission component 410, and the second reinforcing plate 421 extends along the second transmission component 420.

[0093] By adopting the above spatial arrangement, the first transmission component 410 and the second transmission component 420 are arranged at intervals along the reciprocating motion direction, and their length direction is consistent with the motion direction of the rhythm frame 200. With the first reinforcing plate 411 and the second reinforcing plate 421 extending along the length of the transmission component on the side, the overall rigidity and bending resistance of the component are significantly enhanced, giving it the stable force transmission characteristics of a rigid rocker arm. This can effectively suppress deflection and deformation during the motion process and ensure the accuracy of the reciprocating trajectory.

[0094] Meanwhile, the stable frame formed by the rigid body and the reinforcing plate forms a rigid-flexible coupling with the aforementioned elastic transmission components 500, such as U-shaped, L-shaped, I-shaped structures, and a cylindrical spring component: the rigid rocker arm is responsible for directly and reliably transmitting driving force and displacement, while the elastic transmission component 500, such as the U-shaped one, provides flexible buffering during the reversing phase. The two work together to enable the mechanism to maintain high positioning rigidity while having the dual advantages of impact absorption and smooth movement. This avoids the hard impact of a purely rigid structure and overcomes the positioning instability of a purely flexible structure, achieving the best match between rigidity and elasticity, thereby optimizing the smooth reversing effect and system durability.

[0095] It should be noted that in this embodiment, the elastic transmission component 500 can be fixed between the first transmission component 410 and the second transmission component 420 by means of bolts, snap-fit, etc.

[0096] Understandably, referring to Figure 2 , Figure 4 , Figure 6 and Figure 10 In some examples of the present invention, the drive assembly 300 includes a direct drive motor 310, a bearing housing 320, and a crankshaft 330.

[0097] A direct drive motor 310 is mounted on a fixed frame 100 and has a rotating shaft; a bearing housing 320 is mounted on the fixed frame 100; a crankshaft 330 is rotatably mounted on the bearing housing 320, and one end of the crankshaft 330 is connected to the rotating shaft via a coupling; and a first transmission component 410 is eccentrically connected to the crankshaft 330.

[0098] By adopting the above configuration, the drive component 300 is a direct drive structure. The direct drive configuration drives the first transmission component 410, which can eliminate the gaps and lags in the intermediate transmission links, realize the power transmission without delay and with high precision, and greatly improve the response speed and overall rigidity. It not only ensures the accuracy and stability of the motion trajectory, but also forms a rigid-flexible complementarity with the elastic buffer of the elastic transmission component 500. The precise drive of the direct drive is triggered in a timely manner, and the gradual energy absorption of the elastic transmission component 500 softens the impact. The two work together to simplify the structure and reduce energy consumption, while giving the reversing process the advantages of fast response and smooth transition, significantly optimizing the smooth reversing effect and system reliability.

[0099] Specifically, refer to Figure 2 , Figure 4 , Figure 6 and Figure 10 In this embodiment, the drive assembly 300 further includes a transmission sleeve 340, which is rotatably mounted on the crankshaft 330, and the rotation center line of the transmission sleeve 340 is eccentrically set with respect to the rotation center line of the crankshaft 330. The transmission sleeve 340 is fixedly connected to the first transmission component 410.

[0100] The transmission sleeve 340 is eccentrically mounted on the crankshaft 330 and fixedly connected to the first transmission component 410. It can efficiently convert the rotational motion of the crankshaft 330 into the reciprocating linear motion of the first transmission component 410. The eccentricity determines the stroke and is flexibly adjustable. The force changes gradually during rotation. The rigid rocker arm and the elastic transmission component 500 can buffer the impact and make the motion smooth. The structure is compact and easy to integrate. The motion phase is precisely controllable by the crankshaft 330 speed, providing a stable and predictable motion input for smooth reversal.

[0101] Reference Figure 10 In this embodiment, the transmission sleeve 340 includes two sets of transmission units 341, which are spaced apart and rotatably sleeved on the crankshaft 330. One end of the two sets of transmission units 341 is fixedly connected to the first transmission component 410, and a linkage plate 342 connecting the two sets of transmission units 341 is provided between the other ends of the two sets of transmission units 341.

[0102] Two sets of transmission units 341 are spaced apart and rotatably mounted on the crankshaft 330. One end of each unit is fixed to the first transmission component 410, which makes the force distribution more uniform and the rigidity stronger, reducing the off-center load and deformation caused by unilateral load. The other end is connected by a linkage plate 342 to ensure that the two transmission units 341 rotate synchronously, avoiding uneven motion or jamming caused by phase difference. The whole structure forms a stable force transmission frame, which works with the eccentric structure to improve the smoothness and symmetry of reciprocating motion, further optimizing the smooth reversing effect and system durability.

[0103] It should be noted that, in this embodiment, a limiting plate 343 is also provided between the two sets of transmission units 341. The limiting plate 343 is used to limit the interval distance between the two sets of transmission units 341.

[0104] The limiting plate 343 limits the spacing between the two sets of transmission units 341, which can prevent eccentricity drift caused by changes in the unit spacing due to centrifugal force or load fluctuations during operation, and ensure the stability of the geometric relationship of the transmission sleeve 340. At the same time, it avoids interference or collision caused by excessive closeness between the transmission units 341, maintains force symmetry and motion synchronization, and makes the reciprocating motion stroke consistent with the force transmission characteristics, further improving the smoothness of system operation and the reliability of smooth reversal.

[0105] It should also be noted that, referring to Figure 10 In this embodiment, the crankshaft 330 is rotatably mounted on the bearing housing 320 via the first bearing, and the transmission unit 341 includes two detachably connected semicircular parts. The two semicircular parts are connected to each other to form a transmission channel that is sleeved on the crankshaft 330. The transmission channel is rotatably engaged with the crankshaft 330 via the second bearing.

[0106] It should also be noted that, in this embodiment, the transmission unit 341 and the first transmission component 410 can be fixedly connected by means of snap-fit, screw connection or welding.

[0107] Reference Figure 10 In this embodiment, the first transmission component 410 is provided with a snap-fit ​​through hole 412, and the transmission unit 341 is provided with a snap-fit ​​protrusion 344. The snap-fit ​​protrusion 344 is inserted into the snap-fit ​​through hole 412 and is adapted to it, and is fixedly connected by welding.

[0108] The fastening and pre-assembly are achieved by inserting the buckle protrusion 344 into the buckle through hole 412, which greatly simplifies the assembly process, reduces the dependence on high-precision fixtures, and improves production efficiency. The mechanical interlocking characteristics of the buckle can fix the relative position of the two before welding, avoiding misalignment caused by thermal deformation or external force during welding, and ensuring the positional accuracy and coaxiality of the connection after welding. Welding forms a rigid connection on the basis of the pre-fixed buckle, which has the advantages of reliable connection, vibration resistance and anti-loosening, and can withstand high-frequency forces under reciprocating motion and impact loads.

[0109] Meanwhile, this combined structure eliminates the need for additional fasteners such as bolts and pins, reducing the number of parts and assembly costs. While meeting the requirements for high-reliability connections, it achieves a balance between structural simplicity and manufacturing costs, further optimizing the economy and maintainability of the integration of the transmission sleeve 340 and the first transmission component 410.

[0110] Similarly, in this embodiment, the first transmission component 410 and the first reinforcing plate 411, as well as the second transmission component 420 and the second reinforcing plate 421, can be fixedly connected by means of snap-fit, screw connection or welding, such as the first transmission component 410 and the transmission unit 341, and are not limited here.

[0111] Understandably, referring to Figure 1 , Figure 3 , Figure 5 and Figure 8 In this embodiment, the aforementioned mounting bracket 100 is divided into two areas along the front-to-back direction. One area is used to install the drive assembly 300, the transmission assembly, and the flexible reversing structure, while the other area is used to install electrical components such as the control box. The mounting bracket 100 is divided into a mechanical zone 110 and an electrical zone 120 along the front-to-back direction. The mechanical zone 110 is used to centrally house the drive assembly 300, transmission assembly and flexible reversing structure, while the electrical zone 120 is dedicated to housing electronic components such as the control box. This partitioned design can effectively isolate mechanical vibration, dust and electromagnetic interference, improve the stability of system operation and the life of electrical components, while optimizing space utilization and assembly and maintenance efficiency, and making cable routing and heat dissipation paths more orderly.

[0112] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
