Description

Technical Field

[0001] This invention belongs to the field of furniture and home furnishings, specifically a balance positioning component, a drive mechanism, and a folding rocker. Background Technology

[0002] Currently, the mainstream baby rockers on the market are mainly divided into two categories: traditional manual curved rockers and motor-driven electric rockers. Although these products can soothe babies to some extent, their structural design has obvious flaws, especially in adapting to the needs of modern small-sized homes and frequent travel. When attempting to introduce a folding function into electric rockers, considering ease of operation, a core technical challenge arises: how to precisely control the output position of the drive mechanism so that it connects to the drive mechanism when the folding bed is fully unfolded and disengages when the folding bed is folded up. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0004] A balancing positioning component, comprising:

[0005] Relative active components one and two,

[0006] Component three is rotatably connected to Component One and Component Two;

[0007] Component four consists of two sets, both of which are movably mounted on component three. The two sets of component four are connected to or always in contact with component one and component two, respectively.

[0008] In the aforementioned drive mechanism, component four includes a linkage pin disposed on component three;

[0009] Component three is provided with a space slot, and a spring is installed in the space slot;

[0010] One end of the linkage pin is movably installed in the space slot and abuts against the spring in the space slot, while the other end is connected to or always in contact with component one or component two.

[0011] In the aforementioned drive mechanism, the ends of the linkage pin that contact component one and component two are arc-shaped.

[0012] In the aforementioned drive mechanism, a locking pin groove is provided along the length direction on the linkage pin, and a pin body is movably installed in the locking pin groove. The pin body is installed on component three.

[0013] In the aforementioned drive mechanism, component three is provided with a mounting groove, and components one and two are distributed within the mounting groove.

[0014] A drive mechanism includes a balance positioning component and a panning drive component as described above, the panning drive component being mounted on component three.

[0015] In the aforementioned drive mechanism, the rocking drive assembly includes a motor unit and a guide rail installed inside component three. A rocker arm is installed at the output end of the motor unit. One end of the rocker arm is hinged to a connecting rod and a connecting piece. The connecting piece and the guide rail are movably installed.

[0016] A folding rocker bed, comprising:

[0017] The driving mechanism and the slewing mechanism that can be detached from the output end of the driving mechanism, as described above.

[0018] The folding rocker also includes a support mechanism, and the rocking mechanism rotates and moves relative to the support mechanism.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. This invention connects component one and component two of the balance positioning assembly to component three via a rotating shaft, and uses two sets of component four (linkage pins and springs) to achieve synchronous movement of component one and component two. Simultaneously, in the folded state, the connecting piece automatically separates from the joint of the rocking mechanism. This structure allows the entire drive mechanism to adaptively adjust its posture to the folding motion when the rocker is folded and stored. On one hand, component one and component two can rotate synchronously relative to component three, avoiding skewness of component three due to uneven force on one side, thus ensuring that the connecting piece does not shift left or right relative to the joint. On the other hand, after the connecting piece separates from the joint, the rocking drive assembly no longer bears the constraint force from the rocking mechanism, and the motor, linkage, and guide rails are in a free state, preventing misalignment, pulling, or jamming due to the closing of the support mechanism. This ensures both the accuracy and stability of power transmission during rocking and the automatic adaptation to the relative movement of each component during folding, thus combining the electric rocking function and convenient folding and storage function of the rocker.

[0021] 2. This invention designs the rocking mechanism and drive mechanism as a separable structure. When the rocker is unfolded for use, the joints and connecting parts are connected, and the rocking drive assembly can drive the rocking mechanism to perform reciprocating linear motion, achieving a smooth electric rocking function. When folding and storage are required, the joints and connecting parts separate, and the folding body can rotate relative to the joints to complete vertical folding. At the same time, components one and two can rotate relative to component three to complete horizontal folding. This structure effectively solves the technical contradiction in existing electric rockers where the drive module and folding function cannot be simultaneously achieved, realizing the organic unity of electric rocking and convenient folding.

[0022] 3. The drive mechanism of this invention is equipped with two sets of symmetrically distributed linkage pins and springs. The two sets of linkage pins maintain constant contact with component one and component two, respectively. During the unfolding or folding of the balance bar, the linkage pins, under the action of the springs, force the two balance bars to move synchronously, thereby automatically balancing the angle and posture of component three, ensuring that component three moves smoothly and linearly in the horizontal direction, and avoiding angular deviation of component three. This balancing and positioning function effectively ensures that the joint components can be accurately inserted into the connecting components during unfolding, improving the reliability and stability of the folding rocker after repeated unfolding and folding.

[0023] 4. The folding mechanism of the present invention includes a movable body and a synchronizing rod. The movable body is movably mounted on the shaft and can move axially. The movable body is rotatably connected to the first folding body and the second folding body respectively through two synchronizing rods. During folding or unfolding, the two sets of folding bodies achieve synchronous rotation through the linkage of the synchronizing rod and the movable body, avoiding the problem of inconsistent deflection angles on both sides of the joint, preventing angular deviations in the joint, and further ensuring that the joint can be accurately inserted into the connecting piece, thus improving the smoothness of movement and docking accuracy of the folding mechanism.

[0024] 5. In this invention, both the connecting parts and the joint parts (shafts) have chamfered or tapered structures on their opposite sides. During unfolding and docking, the chamfer or tapered surface acts as a guide and automatically aligns the parts, allowing for smooth insertion even with slight positional deviations. Similarly, during folding and separation, the chamfered structure facilitates smooth disengagement. This design reduces docking accuracy requirements, simplifies user operation, and improves ease of use.

[0025] 6. This invention provides a translation component at the end of each of the two sets of folding bodies furthest from the joint. The translation component includes a support base, a translation base, a guide rod, and a guide wheel. In the panning mode, the folding body drives the translation base to move horizontally back and forth relative to the support base, with the guide wheel and guide rod working together to achieve smooth guidance. In the folding mode, the folding body can flip up and down relative to the translation base. This translation component satisfies the requirements of smooth, low-damping horizontal guidance for the panning function, while also accommodating the rotational freedom required for the folding function. The overall structure is compact and rationally designed.

[0026] 7. Through the separate design of the rocking mechanism and the drive mechanism and the linkage folding mechanism of each component, the electric rocking bed of the present invention can bring the two side support mechanisms close to each other in the folded state, and the fence assembly, rocking mechanism and drive mechanism can be folded in sync, greatly reducing the overall volume, making it convenient for home storage and transportation, and effectively solving the problems of fixed structure and large space occupation of existing electric rocking beds.

[0044] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0045] like Figure 1 As shown, a folding electric rocking bed includes support mechanisms 10 located on both sides, a fence assembly 20 for connecting the two sets of support mechanisms 10, a rocking mechanism 30, and a drive mechanism 40, with the rocking mechanism 30 located above the drive mechanism 40.

[0046] like Figure 2 As shown, taking two sets of folding bodies as an example, the horizontal rocking mechanism 30 includes a first folding body 31, a second folding body 32 and a joint. One end of the first folding body 31 and the second folding body 32 rotates relative to the joint.

[0047] like Figure 6 As shown, taking two sets of balance bars as an example, the drive mechanism 40 includes component 41 (first balance bar), component 42 (second balance bar), and a sway drive assembly. One end of component 41 and component 42 is rotatably connected to the sway drive assembly for folding and unfolding. A connector 44 is installed at the output end of the sway drive assembly. The joint and the connector 44 are compatible.

[0048] Component 1 41 and Component 2 42 rotate relative to the horizontal rocking drive assembly and follow the rotation of the first folding body 31 and the second folding body 32 relative to the joint.

[0049] Component 1 41 and Component 2 42 rotate in the up-down direction relative to the horizontal rocking drive assembly, while the first folding body 31 and the second folding body 32 rotate in the horizontal direction relative to the joint.

[0050] Among them, such as Figure 1 As shown, in some embodiments, the support mechanism 10 is a telescopic component that can further retract after the bed is folded to reduce the storage volume of the bed, making it convenient for storage and transportation. The fence assembly 20 is a folding component with a locking structure. The support mechanism 10 and the fence assembly 20 are mature products in the field of folding beds and will not be described in detail here.

[0051] A bed board can be installed on the first folding body 31 and the second folding body 32 to facilitate the baby's sleeping position.

[0052] The ends of components 41 and 42, which are furthest from the horizontal rocking drive assembly, are horizontally rotatably mounted on the support mechanism 10.

[0053] like Figure 12 As shown, in some embodiments, the joint includes a connecting body 33 and a shaft 34 that are vertically connected and have an overall T-shaped structure. The connecting body 33 has a plate-like structure, and the shaft 34 is mounted on the connecting body 33 facing downward.

[0054] like Figure 4 , 12 As shown, in some embodiments, in order to ensure that the two folded bodies can be synchronized during the folding action, a movable body 35 can be movably installed on the shaft 34. The movable body 35 can move along the length of the shaft 34. The movable body 35 is connected to the corresponding folded body via two synchronizing rods 36. One end of the synchronizing rod 36 is rotatably connected to the movable body 35, and the other end is rotatably connected to the corresponding folded body, thereby realizing the simultaneous folding action of the two folded bodies.

[0055] like Figure 12 As shown, the connector 33 is provided with a slot 331, and the movable body 35 is provided with a plug body 351 that is adapted to the slot 331 and has an arc-shaped top.

[0056] like Figure 4 As shown, in some embodiments, the movable body 35 can be a connecting sleeve that slides on the outside of the shaft 34, or it can be a slider hinged to the end of the synchronizing rod 36. The slider can slide along the length of the shaft 34, which can also realize the synchronous folding of the two folding bodies and ensure that the shaft 34 is always facing downward during the folding action. The bottom of the shaft 34 is provided with a chamfer or a tapered structure that is larger at the top and smaller at the bottom, which facilitates the insertion and adaptation with the connecting piece 44. The connecting piece 44 is a cylindrical structure, and the top of the inner side is provided with a chamfer or a tapered structure that is larger at the top and smaller at the bottom.

[0057] In some implementations, if the fence assembly 20 does not employ a locking structure, the following approach is used: Figure 4 As shown, a chamber is provided inside the shaft 34, and the top of the chamber is open. A locking tongue 311 is installed in the chamber through a rotating shaft. A locking groove is provided on the locking tongue 311, and a locking pin 313 is slidably fitted in the locking groove. The locking pin 313 is slidably fitted inside the shaft 34, and the sliding direction is the axial direction of the shaft 34. A side groove 312 is provided on the side of the shaft 34 for the locking tongue 311 to extend out.

[0058] A torsion spring is installed on the rotating shaft connecting the locking tongue 311 and the shaft 34 for resetting the locking tongue 311 and the locking pin 313. A pull strap is installed on the locking pin 313, extending from the top of the shaft 34 for operation. By lifting the pull strap, the locking pin 313 is driven upward. Under the guidance of the locking groove, the locking tongue 311 rotates from the side groove 312 into the cavity, facilitating the downward movement of the moving body 35 and the folding action of the two sets of folding bodies. When the two sets of folding bodies are fully unfolded, the locking tongue 311 locks them from the bottom of the moving body 35. When the moving body 35 is a sliding slider, there are two locking tongues 313, one at the front and one at the back, symmetrically distributed left and right. It should be noted that when the moving body 35 is a slider, the sliding path of the slider needs to partially cover the side groove 312.

[0059] In some implementations, to ensure that the two sets of balance bars remain in a balanced state relative to component 43 during the folding action without angular deviation:

[0060] like Figure 6 , 10 As shown in Figure 11, in some embodiments, the panning drive assembly includes component three 43 and a drive part located inside component three 43. Component three 43 is provided with a mounting groove 45, which is horizontally positioned. Two sets of balance bars are distributed within the mounting groove 45. The two balance bars share a common pivot and are connected to the base 43, or each balance bar can be connected to the base 43 via a separate pivot. Taking the two balance bars sharing a common pivot and being connected to the base 43 as an example, two spatial grooves 46 are provided in the mounting groove 45, symmetrically distributed around the pivot. Component four includes a linkage pin 47 installed in the spatial groove 46. A spring is installed in the spatial groove 46 to act on one end of the linkage pin 47. A locking pin groove 48 is provided along the length direction of the linkage pin 47. A pin body 481 is slidably installed in the locking pin groove 48. The pin body 481 is connected to component three 43 and is used to constrain the linkage pin 47 from separating from the spring in the spatial groove 46, so that the linkage pin 47... The other end of 7 is exposed on the outside of the space slot 46 and is always in contact with the corresponding balance bar (or in contact with it, but in a contacting state when in contact). The contact surface is an arc surface, so that when the two sets of balance bars are horizontally unfolded or folded, the component 3 43 can be linearly translated in the horizontal direction, and the position of the connector 44 is always parallel to the movement path of the component 3 43 and will not be angularly offset around the axis of rotation connecting the balance bar and the component 3 43. This ensures that the shaft 34 and the connector 44 are plugged in and connected when unfolded, so as to balance the position of the component 3 43.

[0061] In some embodiments, to enable the connecting member 44 and the shaft 34 to perform reciprocating linear motion after connection, the following scheme is adopted:

[0062] like Figures 7 to 8As shown, the drive unit includes a motor assembly 431 and a guide rail 434 installed inside component 3 43. A rocker arm 432 is installed at the output end of the motor assembly 431. One end of the rocker arm 432 is connected to a slider for mounting the connector 44 via a connecting rod 433 or is directly connected to the connector 44.

[0063] In some embodiments, in order to guide the linear movement of the connector 44, one method is that the slider or connector 44 can move linearly on the guide rail 434, which is fixedly set; another method is that the slider or connector 44 and the guide rail 434 are fixedly connected and move back and forth relative to the component 3 43, and the component 3 43 constrains the guide rail 434 so that it can only move linearly, and the direction of movement is horizontal back and forth.

[0064] Since the connector 44 moves horizontally back and forth and the shaft 34 moves vertically, there will be a positional deviation when the connector 44 and the shaft 34 are plugged in during actual use. The taper or chamfer at the bottom of the shaft 34 can be used to adaptively adjust the position of the connector 44 in its own direction of movement until the plugging connection is completed.

[0065] As the two sets of folding bodies fold and unfold in the vertical direction, and the two sets of balance bars fold and unfold in the horizontal direction, the bottom of the shaft 34 and the top of the connector 44 are used to automatically guide the position during the process of connecting the shaft 34 and the connector 44. During the guidance, the position of the connector 44 will change in the direction of movement. After the shaft 34 and the connector 44 are connected, the motor unit 431 can automatically drag the connector 44 back to its original position.

[0066] Similarly, when the shaft 34 and the connecting piece 44 separate, the connecting piece 44 will also change position in the direction of movement. After separation, the motor unit 431 can automatically drag the connecting piece 44 back to the initial set position.

[0067] In some embodiments, the following scheme is adopted to realize the translational and rotational folding actions of the lateral rocking mechanism 30 relative to the support mechanism 10:

[0068] like Figure 2 , Figure 5 As shown, each of the two sets of support mechanisms 10 is provided with a translation component on one side of the opposite side. The translation component is located below the fence assembly 20 and above the two sets of balance bars.

[0069] Two sets of translation components are rotatably connected to the corresponding folding bodies. The folding bodies flip up and down relative to the translation components to achieve folding. The translation components are used to drive the corresponding folding bodies to translate, and work with the drive mechanism 40 to achieve the panning action.

[0070] Specifically, such as Figure 5As shown, the translation component includes a support base 11 mounted on the support mechanism 10. A translation platform 12 is provided in the middle of the support base 11 near the translation mechanism 30. A set of guide rods 13 is provided on each of the front and rear sides of the translation platform 12. Each set of guide rods 13 includes two rods distributed vertically. A translation seat 37 is installed at the end of the first folding body 31 and the second folding body 32 away from the connecting body 33. Connecting parts 321 are installed at both ends of the translation seat 37. The connecting parts 321 are tubular, cylindrical, or sleeve-shaped structures. The connecting parts 321 and the corresponding folding bodies are connected by... The connecting pin is connected to the folding body. The end of the folding body away from the joint is provided with an arc-shaped groove 322 for the folding body to flip up and down. The arc-shaped groove 322 is located inside the connecting part 321. The connecting pin can move in the arc-shaped groove 322. The combination of the connecting pin and the arc-shaped groove 322 can control the folding body to have two extreme positions. One extreme position is that it is horizontal after unfolding. The other extreme position is that the distance between the two sets of support mechanisms 10 is the design distance when folding (that is, to meet the thickness requirements of the shaker after folding). This can facilitate the storage and transportation of the shaker.

[0071] The translation seat 37 is provided with a translation groove 38 on the side facing the translation platform 12. The translation platform 12 is movably installed in the translation groove 38, so that the translation seat 37 restricts the guide wheel 39 from disengaging from the guide rod 13 in the front and back. Each end of the translation groove 38 is provided with a set of guide grooves 310, and guide wheels 39 are installed in both sets of guide grooves 310. The guide wheels 39 and guide rods 13 are movably installed. The two rods are distributed on the upper and lower sides of the guide wheels 39, which are used to guide the translation seat 37 in the horizontal direction. The lower rod is used to support the folding body, so as to realize the overall horizontal rocking of the rocking mechanism 30 relative to the support mechanism 10.

[0072] like Figures 1 to 14 As shown, when unfolded, the connecting body 33 moves downward, and the two sets of support mechanisms 10 move away from each other synchronously. During the downward movement of the connecting body 33, the moving body 35 drives the two sets of folding bodies to unfold synchronously via the synchronizing rod 36, and the shaft 34 moves downward and gradually approaches the connecting piece 44. At the same time, the two sets of balance rods rotate horizontally relative to the support mechanism 10 and unfold. Under the action of the two linkage pins 47 on the left and right, the component 33 moves gradually downward towards the shaft 34. A chamfer or conical structure is provided at the end where the shaft 34 and the connecting piece 44 are connected to facilitate the connection between the two. During the connection between the two, the connecting piece 44 will change position in the direction of movement under the action of the shaft 34. After the shaft 34 and the connecting piece 44 are connected, the motor unit 431 can automatically drag the connecting piece 44 back to its original position.

[0073] When the folding mechanism is in motion, the motor unit 431 drives the crank 432 to rotate, which in turn drives the connecting piece 44 to reciprocate linearly relative to the component 34 via the connecting rod 433. Since the connecting piece 44 is connected to the shaft 34, under the guidance of the guide rod 13 and the guide wheel 39, the two sets of folding bodies drive the translation seats 37 at their ends to move back and forth relative to the support seat 11.

[0074] When folding, if a locking tongue 311 is provided on the shaft 34, the locking tongue 311 is released from the moving body 35 by pulling the locking pin with the operating strap, and then the connecting body 33 is moved upward; if a locking tongue 311 is not provided on the shaft 34, the connecting body 33 is moved upward directly; then the two sets of folding bodies rotate relative to the translation seat 37, and the support mechanisms 10 on both sides move closer to each other, while the two sets of balance bars move closer horizontally, and the component 43 moves horizontally. During the movement, the connecting piece 44 and the shaft 34 first keep sliding vertically. When they are disengaged, the motor unit 431 can automatically drag the connecting piece 44 back to the initial set position.

[0075] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made to the technical solutions and inventive concepts of the present invention should all be covered within the scope of protection of the present invention.
