Description

Technical Field

[0001] This utility model relates to the technical field of baby products, specifically to an electric baby rocker. Background Technology

[0002] Early baby rockers were mostly manually operated, requiring parents to push or swing them to help soothe babies to sleep. However, manual rockers were labor-intensive, could not be used continuously, and required long-term parental supervision, failing to meet the modern family's demands for convenience and efficiency. With advancements in electrical and automation technologies, electric rockers emerged. Early electric cradles achieved automatic rocking through simple mechanical transmissions (such as a motor-driven crank-connecting rod mechanism), but their functionality was limited, their movement trajectory was singular, and the swing amplitude was fixed, resulting in a mediocre user experience. Utility Model Content

[0003] This invention proposes an electric baby rocker, which features a movable component connected to the bed frame on one side of the fixed frame, and a connecting sliding mechanism between the fixed frame and the movable component, including a vertical sliding assembly and a horizontal sliding assembly, enabling the bed frame to move vertically and horizontally. Simultaneously, a power mechanism on the fixed frame drives the movable component to alternately perform reciprocating movements in the vertical and horizontal directions according to a preset motion trajectory via a mechanical transmission assembly, causing the bed frame to ultimately exhibit a semi-elliptical motion trajectory. Compared to the single motion trajectory of traditional electric rockers, this design greatly enriches the bed frame's motion trajectory.

[0004] An electric baby rocker designed for this purpose includes a bed frame and a fixed frame, wherein one side of the fixed frame is provided with a movable part that is connected to the bed frame;

[0005] A connecting sliding mechanism is provided between the fixed frame and the movable component; the connecting sliding mechanism includes an up-down sliding component for guiding the bed and the movable component to move in the vertical direction, and a left-right sliding component for guiding the bed to move in the horizontal direction.

[0006] The fixed frame is equipped with a power mechanism, and a mechanical transmission component is provided on the transmission connection between the power mechanism and the moving part. The power mechanism drives the moving part to perform reciprocating motion in the up-down and left-right directions alternately according to the preset motion trajectory through the mechanical transmission component, so that the bed ultimately presents a semi-elliptical trajectory motion.

[0007] The mechanical transmission assembly includes a gear transmission component mounted on a movable part, and a first gear mounted on the output end of the power mechanism.

[0008] The gear transmission component is provided with a continuous elliptical gear ring, and the first gear meshes with the elliptical gear ring; the power mechanism drives the first gear to rotate, and through the meshing action of the first gear with the elliptical gear ring, it drives the gear transmission component to produce periodically changing displacement, thereby causing the moving parts to alternately produce compound motion in the up-down and left-right directions, so that the bed ultimately presents a semi-elliptical trajectory motion.

[0009] The bed and moving parts move in either the forward or reverse direction through a full circle of elliptical gears.

[0010] The bed and moving parts move back and forth in a semi-circular motion via a semi-circular elliptical gear ring.

[0011] The bed and the moving parts move back and forth through the straight section of the elliptical gear ring;

[0012] The gear transmission component and the moving component are either detachably connected or integrally formed.

[0014] The anti-jamming structure includes a bearing mounted on the drive shaft and an elliptical track groove mounted on the moving part. During the movement of the moving part, the bearing and the elliptical track groove form a rolling fit to avoid rigid jamming between the moving part and the fixed frame.

[0015] The vertical sliding assembly includes a vertical rod and a vertical block; the horizontal sliding assembly includes a horizontal rod and a fixed base.

[0016] The movable component is provided with vertical rods arranged at left and right intervals. Each vertical rod has vertical blocks at both its upper and lower ends, and the vertical blocks are fitted on the outside of the vertical rod.

[0017] The fixed frame has two fixed seats at vertically spaced intervals at the upper and lower ends of each vertical rod. The fixed frame is assembled with the movable part. Each fixed seat is located between the corresponding two vertical blocks and is connected in series by a horizontal bar to form a connecting sliding mechanism that allows the movable part to slide up and down and left and right relative to the fixed frame. The sliding cooperation between the vertical block and the vertical rod realizes the up and down reciprocating motion of the movable part, and the sliding cooperation between the fixed seat and the horizontal bar realizes the left and right reciprocating motion of the movable part. The up and down reciprocating motion and the left and right reciprocating motion operate independently and do not interfere with each other.

[0018] The cooperation between the vertical block and the inner side of the movable part forms a first limiting structure for up-and-down reciprocating motion, and the cooperation between the fixed seat and the two vertical blocks forms a second limiting structure for left-and-right reciprocating motion.

[0019] The power mechanism includes a reducer mounted on a fixed frame, and the mechanical transmission assembly includes a first gear, a second gear, and a third gear for transmission connection with the moving parts. The power mechanism also includes a drive shaft rotatably mounted on the fixed frame.

[0020] The reducer is provided with an output shaft connected to the second gear, and the third gear is connected to the drive shaft;

[0021] The second gear meshes with the third gear, and the first gear and the third gear are either detachably connected or integrally formed.

[0022] The output shaft of the reducer operates by acting on the moving part through the second gear, the third gear, and the first gear, thereby driving the moving part to move.

[0023] The power mechanism includes a motor and a synchronous belt assembly mounted on a fixed frame. The motor is connected to a reducer via the synchronous belt assembly to increase the torque output by the motor.

[0024] The timing belt assembly includes a first timing pulley, a second timing pulley, and a timing belt covering the first timing pulley and the second timing pulley;

[0025] The reducer is provided with an input shaft connected to the second synchronous pulley, and the motor shaft of the motor is connected to the first synchronous pulley.

[0026] The movable component is provided with a fastening structure between itself and the bed frame to fix the movable component to the bed frame;

[0027] The fastening structure includes a connector mounted on the bed frame and a fastening component mounted on the movable component;

[0028] The connector is provided with a mounting groove, and the mounting groove is provided with an anti-detachment block; the fastener is provided with a slot and a groove.

[0029] The fastening element protrudes from the outside of the movable element. The movable element is assembled with the bed frame. The fastening element passes through the mounting groove of the connector. One end of the connector is limited in the slot of the fastening element. The anti-disengagement block is inserted into the slot to fix the movable element to the bed frame.

[0030] The fasteners and movable parts are either detachably connected or integrally formed.

[0031] The mounting frame is provided with a mounting slot for installing the power mechanism;

Compared to the single motion trajectory of traditional electric rocker beds, this design greatly enriches the bed frame's motion trajectory. Attached Figure Description

[0048] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. In order to make the above-mentioned objects, features and advantages of the present application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0049] See Figures 1-13 An electric baby rocker includes a bed frame 1 and a fixing frame 2, wherein a movable part 3 connected to the bed frame 1 is provided on one side of the fixing frame 2;

[0050] A connecting sliding mechanism is provided between the fixed frame 2 and the movable part 3; the connecting sliding mechanism includes an up-down sliding component 4 for guiding the bed 1 and the movable part 3 to move in the vertical direction, and a left-right sliding component 5 for guiding the bed 1 to move in the horizontal direction.

[0051] The fixed frame 2 is equipped with a power mechanism 6, and a mechanical transmission component 7 is provided on the power mechanism 6 and the movable part 3 for transmission connection. The power mechanism 6 drives the movable part 3 to perform reciprocating motion in the up and down and left and right directions alternately according to the preset motion trajectory through the mechanical transmission component 7, so that the bed 1 finally presents a semi-elliptical trajectory motion.

[0052] By installing a movable component 3 connected to the bed frame 1 on one side of the fixed frame 2, and a connecting sliding mechanism including a vertical sliding component 4 and a horizontal sliding component 5 between the fixed frame 2 and the movable component 3, the bed frame 1 can move in both vertical and horizontal directions. Simultaneously, the power mechanism 6 on the fixed frame 2 drives the movable component 3 to alternately perform reciprocating movements in the vertical and horizontal directions according to a preset motion trajectory via a mechanical transmission component 7, causing the bed frame 1 to ultimately exhibit a semi-elliptical trajectory movement. Compared to the single motion trajectory of traditional electric rocker beds, this design greatly enriches the motion trajectory of the bed frame 1.

[0053] The mechanical transmission assembly 7 includes a gear transmission component 8 disposed on the movable part 3, and a first gear 9 disposed on the output end of the power mechanism 6;

[0054] The gear transmission component 8 is provided with a continuous elliptical gear ring 10, and the first gear 9 meshes with the elliptical gear ring 10; the power mechanism 6 drives the first gear 9 to rotate, and through the meshing action of the first gear 9 with the elliptical gear ring 10, the gear transmission component 8 is driven to produce periodically changing displacement, so that the moving part 3 alternately produces compound motion in the up and down and left and right directions, so that the bed 1 ultimately presents a semi-elliptical trajectory motion.

[0055] The mechanical transmission assembly 7 includes a gear transmission component 8 mounted on the movable part 3. The gear transmission component 8 has a continuous elliptical gear ring 10, which meshes with the first gear 9 at the output end of the power mechanism 6. When the power mechanism 6 drives the first gear 9 to rotate, the meshing action of the two drives the gear transmission component 8 to produce periodically changing displacements, thereby causing the movable part 3 to alternately generate compound movements in the up-down and left-right directions, resulting in the bed 1 exhibiting a semi-elliptical trajectory movement. This gear transmission structure features accurate transmission ratio and high transmission efficiency, precisely converting the rotational motion of the power mechanism 6 into compound linear motion in the up-down and left-right directions of the movable part 3. Compared to other transmission methods, gear transmission has higher reliability, is less prone to slippage, and extends the service life of the electric rocker. Furthermore, by adjusting the gear parameters, the movement amplitude and frequency of the bed 1 can be easily changed.

[0056] The bed 1 and the movable part 3 move in the forward or reverse direction through a full circle of elliptical gear ring 10.

[0057] The bed 1 and the movable part 3 make a back-and-forth semi-circular motion through a semi-circular elliptical gear ring 10;

[0058] The bed 1 and the movable part 3 move back and forth through the straight part of the elliptical gear ring 10.

[0059] The gear transmission component 8 and the movable component 3 are either detachably connected or integrally formed.

[0060] The bed frame 1 and the moving part 3 can achieve various modes of movement through different parts of the elliptical gear ring 10, such as full-circle forward or reverse movement, back-and-forth semi-circular movement, and back-and-forth translational movement. This diverse range of movement provides a rich experience for the infant. Furthermore, the gear transmission component 8 and the moving part 3 can be detachably connected or integrally molded. Detachable connection facilitates the replacement of damaged parts, reducing maintenance costs; integral molding improves the overall structural strength and stability, ensuring reliable movement.

[0061] In this embodiment, the gear transmission component 8 has a cavity, the elliptical gear ring 10 is disposed in the cavity, and the first gear 9 is installed in the gear transmission component 8 and meshes with several teeth on the elliptical gear ring 10.

[0062] The power mechanism 6 and the movable part 3 are provided with an anti-jamming structure to prevent the movable part 3 from jamming during the movement. The power mechanism 6 includes a drive shaft 11 that forms the output end of the power mechanism 6 and is connected to the movable part 3 for transmission.

[0063] The anti-jamming structure includes a bearing 12 on the drive shaft 11 and an elliptical track groove 13 on the movable part 3. During the movement of the movable part 3, the bearing 12 and the elliptical track groove 13 form a rolling fit to avoid rigid jamming between the movable part 3 and the fixed frame 2.

[0064] The anti-jamming structure effectively prevents rigid jamming between the moving part 3 and the fixed frame 2, greatly improving the reliability and stability of the electric baby rocker. In traditional electric baby rockers, mechanical transmission components are prone to jamming after prolonged operation due to friction, wear, or installation errors. The rolling fit design of this product reduces frictional resistance between components and minimizes wear. Even under long-term continuous operation, it ensures that the moving part 3 moves smoothly along the preset trajectory, guaranteeing the normal operation of the baby electric rocker.

[0065] In this embodiment, the movable part 3 is provided with a mounting groove 36, and a mounting plate 37 is provided on one side of the mounting groove 36. The gear transmission part 8 is fixed on the other side of the mounting groove 36, and the mounting plate 37, the mounting groove 36 and the gear transmission part 8 are fixedly connected by screws.

[0066] The other side of the mounting groove 36 has a recess for mounting the gear transmission component 8.

[0067] In this embodiment, a mounting block 38 is provided on the side of the mounting plate 37 corresponding to the cavity of the gear transmission component 8. The mounting block 38 and the mounting plate 37 are fixedly connected by screws. An elliptical track groove 13 is formed at the step engagement between the inner side of the movable component 3 and the mounting plate 37, while an inner elliptical track groove 39 is formed at the step engagement between the mounting block 38 and the mounting plate 37. The bearing 12 is limited vertically between the elliptical track groove 13 and the inner elliptical track groove 39. This allows the bearing 12 to roll relative to each other along the elliptical track groove 13 and the inner elliptical track groove 39, making it less likely for them to disengage.

[0068] The vertical sliding assembly 4 includes a vertical rod 14 and a vertical block 15; the horizontal sliding assembly 5 includes a horizontal rod 16 and a fixed base 17.

[0069] The movable component 3 is provided with vertical rods 14 arranged at left and right intervals. Each vertical rod 14 has vertical blocks 15 at both its upper and lower ends, and the vertical blocks 15 are sleeved on the outside of the vertical rod 14.

[0070] The fixed frame 2 has two fixed seats 17 arranged vertically at intervals at the vertical blocks 15 at the upper and lower ends of each vertical rod 14. The fixed frame 2 is assembled with the movable part 3. Each fixed seat 17 is located between the corresponding two vertical blocks 15 and is connected in series by a horizontal bar 16 to form a connecting sliding mechanism that allows the movable part 3 to slide up and down and left and right relative to the fixed frame 2. The sliding cooperation between the vertical blocks 15 and the vertical rod 14 realizes the up and down reciprocating motion of the movable part 3, and the sliding cooperation between the fixed seat 17 and the horizontal bar 16 realizes the left and right reciprocating motion of the movable part 3. The up and down reciprocating motion and the left and right reciprocating motion operate independently and do not interfere with each other.

[0071] In this embodiment, the movable part 3 has two spaced-apart mounting cavities 40 on its left and right inner sides, and a through hole at the top of the movable part 3 that connects to the mounting cavities 40 and is used to insert the vertical rod 14. A vertical block 15 is installed in each mounting cavity 40. The vertical block 15 can be formed by splicing two connecting blocks 41, which are fixedly connected by screws; or, the vertical block 15 can be formed by a single part with a receiving groove for rubbing the vertical rod 14. The outer side of the vertical block 15 has a first transverse through hole for inserting the horizontal rod 16. The fixed base 17 has a second transverse through hole for inserting the horizontal rod 16.

[0072] The vertical sliding assembly 4 consists of a vertical rod 14 and a vertical block 15, while the horizontal sliding assembly 5 consists of a horizontal rod 16 and a fixed seat 17. This unique structural design forms a connecting sliding mechanism that allows the movable part 3 to slide vertically and horizontally relative to the fixed frame 2. The sliding engagement between the vertical block 15 and the vertical rod 14 enables the vertical reciprocating motion of the movable part 3, while the sliding engagement between the fixed seat 17 and the horizontal rod 16 enables the horizontal reciprocating motion of the movable part 3. Furthermore, the vertical and horizontal reciprocating motions operate independently and do not interfere with each other. This independent operation mechanism makes the movement of the bed 1 more flexible and precise, enabling accurate achievement of the preset semi-elliptical trajectory movement.

[0073] The vertical block 15 and the inner side of the movable part 3 cooperate to form a first limiting structure for up-and-down reciprocating motion, and the fixed seat 17 and the two vertical blocks 15 cooperate to form a second limiting structure for left-and-right reciprocating motion.

[0074] The engagement between the vertical block 15 and the inner side of the movable part 3 forms a first limiting structure, while the engagement between the fixed seat 17 and the two vertical blocks 15 forms a second limiting structure. These two limiting structures provide reliable constraints and guidance for the movement of the movable part 3, ensuring that it will not deviate or misalign during its vertical and horizontal movements, further guaranteeing the accuracy and stability of the bed 1's movement trajectory. During the operation of the electric rocker, the limiting structures effectively prevent the movable part 3 from deviating from its normal movement track due to external forces or its own inertia.

[0075] The power mechanism 6 includes a reducer 18 mounted on the fixed frame 2, the mechanical transmission assembly 7 includes a first gear 9, a second gear 19 and a third gear 20 for transmission connection with the moving part 3, and the power mechanism 6 includes a drive shaft 11 rotatably mounted on the fixed frame 2.

[0076] The reducer 18 is provided with an output shaft 21 connected to the second gear 19, and the third gear 20 is connected to the drive shaft 11;

[0077] The second gear 19 meshes with the third gear 20, and the first gear 9 and the third gear 20 are either detachably connected or integrally formed.

[0078] The output shaft 21 of the reducer 18 operates through the second gear 19, the third gear 20 and the first gear 9, acting on the movable part 3 to drive the movable part 3 to move.

[0079] In this embodiment, both the reducer 18 and the motor 22 are fixed to a mounting bracket 42, the synchronous belt assembly 23 is mounted on the top of the mounting bracket 42, and the mounting bracket 42 is installed in the fixing slot 34 of the fixing frame 2.

[0080] In the power mechanism 6, the reducer 18 is connected to the second gear 19 via the output shaft 21, and the third gear 20 is connected to the drive shaft 11. The second gear 19 and the third gear 20 mesh, while the first gear 9 and the third gear 20 are detachably connected or integrally formed. This multi-stage gear transmission design effectively reduces the output speed of the power mechanism 6 while increasing torque, providing a stable and powerful driving force for the moving part 3. When driving the moving part 3 to achieve complex semi-elliptical trajectory motion, stable power output ensures the continuity and accuracy of the motion, avoiding motion stuttering or unevenness caused by insufficient power.

[0081] The power mechanism 6 includes a motor 22 and a synchronous belt assembly 23 mounted on the fixed frame 2. The motor 22 is connected to the reducer 18 through the synchronous belt assembly 23 to increase the torque output by the motor 22.

[0082] The timing belt assembly 23 includes a first timing pulley 24, a second timing pulley 25, and a timing belt 26 covering the first timing pulley 24 and the second timing pulley 25;

[0083] The reducer 18 is provided with an input shaft 27 connected to the second synchronous pulley 25, and the motor shaft of the motor 22 is connected to the first synchronous pulley 24.

[0084] The power mechanism 6 uses a motor 22 connected to a reducer 18 via a synchronous belt assembly 23. The synchronous belt assembly 23 includes a first synchronous pulley 24, a second synchronous pulley 25, and a synchronous belt 26. This design effectively increases the torque output of the motor 22, providing more power to the electric rocker. Synchronous belt drives offer advantages such as smooth transmission and low noise. Compared to traditional chain or gear drives, synchronous belt drives do not produce significant vibration or noise, creating a quiet sleeping environment for infants. Furthermore, synchronous belt drives have a simple structure, are easy to maintain, and do not require frequent lubrication, reducing usage and maintenance costs. In addition, by appropriately selecting the parameters of the synchronous belt assembly 23, the transmission ratio can be adjusted according to actual needs, matching the power output of the motor 22 with the operating requirements of the electric rocker.

[0085] The movable part 3 is provided with a fastening structure between it and the bed 1, so that the movable part 3 is fixedly connected to the bed 1;

[0086] The fastening structure includes a connector 28 disposed on the bed 1 and a fastening member 29 disposed on the movable member 3;

[0087] The connector 28 is provided with a mounting groove 30, and the mounting groove 30 is provided with an anti-detachment block 31. The fastener 29 is provided with a slot 32 and a slot 33.

[0088] The fastening element 29 protrudes outward from the movable element 3. The movable element 3 is assembled with the bed 1. The fastening element 29 passes through the mounting groove 30 of the connector 28. One end of the connector 28 is limited in the slot 32 of the fastening element 29. The anti-detachment block 31 is inserted into the slot 33 to fix the movable element 3 to the bed 1.

[0089] The fastener 29 and the movable part 3 are either detachably connected or integrally formed.

[0090] The fastening structure between the movable part 3 and the bed frame 1 consists of a connector 28 on the bed frame 1 and a fastening part 29 on the movable part 3. The mounting groove 30 and anti-detachment block 31 on the connector 28 cooperate with the slot 32 and slot 33 on the fastening part 29 to achieve a fixed connection between the movable part 3 and the bed frame 1. This fastening structure features a strong connection and convenient installation and disassembly. During installation, simply pass the fastening part 29 through the mounting groove 30 of the connector 28, so that one end of the connector 28 is limited in the slot 32, and insert the anti-detachment block 31 into the slot 33 to quickly fix the movable part 3 to the bed frame 1. The operation is simple and quick, requiring no additional tools. During disassembly, the two can also be easily separated, facilitating the maintenance or replacement of the bed frame 1 or the movable part 3. Furthermore, the robust connection ensures that the bed frame 1 and the movable part 3 will not loosen or fall off during the operation of the electric rocker, ensuring the safety of the baby and improving the reliability and stability of the product.

[0094] The fixed slot 34 within the fixed frame 2 is used to install the power mechanism 6. This design makes efficient use of the internal space of the fixed frame 2, resulting in a more compact overall structure for the electric rocker. Installing the power mechanism 6 within the fixed slot 34 not only protects it from dust and debris that could affect its normal operation, but also, the support rods 35 on both sides of the fixed frame 2 are fixedly connected to the base, enhancing the support strength and stability of the fixed frame 2.

[0095] In this embodiment, the movable part 3 has a triangular connecting part 44 protruding from the outside, and the fastening part 29 has a concave position corresponding to the connecting part 44. The movable part 3 and the fastening part 29 are fixedly connected by the cooperation of the connecting part 44 and the concave position, and then the connecting part 44 and the concave position are connected by bolts or connecting pins.

[0096] In this embodiment, the fixing frame 2 has fixing slots on the left and right sides for inserting connecting rods, and the support rod 35 is fixedly connected to the fixing frame 2 through the connecting rod.

[0097] In this embodiment, the reducer 18 is a worm gear reducer or a gear transmission reducer.
