Description

Technical Field

[0001] This utility model relates to the field of swing device technology, and in particular to an electric swing device. Background Technology

[0002] Strollers, cradles, or cribs are indispensable tools in childcare. To soothe infants and toddlers, especially to help them fall asleep peacefully, consistent and rhythmic rocking is a very effective method. In long-term practice, parents or caregivers often need to manually push and pull the stroller or cradle repeatedly to create rocking. This method not only consumes a great deal of the caregiver's time and energy, preventing them from handling other tasks simultaneously, but also makes it difficult to maintain a steady and even rocking frequency and amplitude after prolonged rocking, potentially affecting the soothing effect due to sudden changes in the rocking rhythm.

[0003] Of course, some electric swing devices have also appeared on the market. However, the structural design of these devices is generally relatively simple. For example, they use eccentric wheel transmission, which results in problems such as high noise, uneven vibration, and easy damage.

[0004] Therefore, it is necessary to further improve and perfect the existing technology to overcome these shortcomings, and this utility model is made based on this situation. Utility Model Content

[0019] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, wherein:

[0020] Figure 1 This is one of the three-dimensional structural schematic diagrams of this utility model;

[0021] Figure 2 This is the second three-dimensional structural schematic diagram of this utility model;

[0022] Figure 3 This is an exploded view of the present invention. Detailed Implementation

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Please see Figures 1 to 3 This embodiment discloses an electric rocking device, which is designed to provide a smooth, gentle and lasting automatic rocking power for childcare products such as strollers, cribs and cradles.

[0025] As shown in the figure, the overall structure of this electric rocking device includes a fixed base 1 and a movable base 6, which are dynamically connected by a planetary gear reduction structure and a crank-rocker structure. In use, the fixed base 1 and the movable base 6 are fixed at different positions on the object to be driven (such as the frame of a stroller). Through the operation of the device, the relative reciprocating motion between the two is realized, thereby driving the entire object to rock.

[0026] The mounting base 1 houses the drive motor 2, power supply assembly 3, and planetary gear reduction structure 4. This integrated design makes the entire device compact, easy to carry, and easy to install.

[0027] In this embodiment, the power supply component 3 is preferably one or more rechargeable batteries or dry cell batteries disposed inside the mounting base 1. This built-in power supply design eliminates the need for external power cords, avoiding the inconvenience and safety hazards caused by tangled wires, and greatly enhancing the portability and flexibility of the device.

[0028] The core transmission component of the device is a planetary gear reduction structure 4. The output shaft of the drive motor 2 is directly connected to the sun gear 41 of this structure. The planetary gear reduction structure 4 also includes a housing 43, which is detachably fixed to the mounting base 1 by screws or other fasteners for easy inspection and maintenance. An internal gear ring 431 is fixedly mounted on the inner wall of the housing 43. A planet carrier 42 is rotatably mounted on the mounting base 1, and at least one (shown as one in the figure) planet gear 44 is rotatably connected thereto. The planet gear 44 meshes with both the central sun gear 41 and the peripheral internal gear ring 431.

[0029] When the drive motor 2 starts, its power is transmitted to the planetary gears 44 via the sun gear 41. Since the internal gear ring 431 is stationary, the planetary gears 44, driven by the sun gear 41, will rotate on their own axis and revolve around the sun gear 41 along the trajectory of the internal gear ring 431, thus driving the planet carrier 42 to rotate as a whole. Compared with the traditional eccentric wheel structure, this transmission method has significant advantages such as a large transmission ratio, extremely smooth operation, extremely low noise, strong load-bearing capacity, and compact structure. It can output a gentle yet powerful rocking motion, perfectly simulating the rhythm of artificial soothing, providing the best comfort experience for the baby.

[0030] One end of the rocker arm 5 is rotatably connected to the central axis of the planetary gear 44 via a pin. It is worth noting that this pin is preferably designed as a detachable structure, facilitating the separation of the rocker arm 5 from the planetary gear 44 for product storage. The other end of the rocker arm 5 is rotatably connected to the movable seat 6. Through this crank-rocker structure design, the complex compound rotation (rotation plus revolution) of the planetary gear 44 is converted into the reciprocating oscillation of the movable seat 6 relative to the fixed seat 1, with a specific trajectory and frequency.

[0031] In order to reliably fix the device to objects such as strollers, this embodiment is designed with a first fastening structure 7 and a second fastening structure 8.

[0032] See Figures 1-3The first fastening structure 7 is used to fix the fixing seat 1 to the rod of the object. It includes a connecting seat 71, on which a lower clamping arm 72 is provided and rotatably connected to an upper clamping arm 73. Both the upper and lower clamping arms are designed to be arc-shaped to better fit the circular or elliptical rod. To enhance the clamping friction and stability, the inner surfaces of the lower clamping arm 72 and the upper clamping arm 73 facing each other are provided with anti-slip textures 721 and 731, or they can be configured to be fitted with an elastic pad made of rubber or silicone.

[0033] To achieve rapid locking, the structure incorporates a locking assembly. This assembly includes a knob 74 rotatably connected to the upper clamping arm 73, a pull rod 75 threadedly engaged with the knob 74, and a collar 751 at the end of the pull rod 75. Correspondingly, the lower clamping arm 72 has a pin 76, and the collar 751 is fitted onto the pin 76. During installation, after the upper and lower clamping arms grip the rod, rotating the knob 74 causes the pull rod 75 to shorten due to the threaded action, thereby firmly tightening the upper clamping arm 73 and the lower clamping arm 72, achieving reliable clamping and fixation.

[0034] To further enhance modularity and versatility, the connector 71 is preferably designed to be detachable from the mounting base 1. For example... Figure 3 As shown, the connection method is as follows: a plug-in protrusion 11 is provided on the fixed base 1, and a corresponding plug-in interface 711 is provided on one side of the connecting base 71. During installation, the plug-in interface 711 is first aligned with the plug-in protrusion 11 and inserted. A snap-fit ​​protrusion 712 is provided on the other side of the connecting base 71, and a corresponding snap-fit ​​77 is provided on the fixed base 1, with a snap-fit ​​tongue 771 on the snap-fit ​​tongue 771. When the connecting base 71 is inserted into place, the snap-fit ​​tongue 771 will automatically snap onto the snap-fit ​​protrusion 712, completing the locking. An elastic reset element 78 (such as a spring) is also provided between the two to continuously provide a reset force to the snap-fit ​​tongue 77, ensuring the reliability of the snap-fit. This "one-plug-one-snap" quick-release design makes it extremely convenient to change clamps of different specifications or to disassemble and store them.

[0035] A second fastening structure 8 is provided on the movable seat 6 for securing it to another location. In this embodiment, the second fastening structure 8 can be simplified to at least one strip-shaped mounting hole 81 opened on the movable seat 6. The user can use straps, cable ties, or fasteners (such as screws) to pass through the strip-shaped mounting hole 81 to bind or secure it to any suitable position on the stroller. Furthermore, the mounting surface of the movable seat 6 is preferably an arc-shaped mounting surface 82, which allows it to better fit rods of different diameters, resulting in a larger contact area and a more secure fixation.

[0036] Summary of working principles:

[0037] The user first securely installs the device onto the stroller frame using the first fastening structure 7 and the second fastening structure 8. After pressing the switch, the power supply component 3 supplies power to the drive motor 2, which in turn drives the planetary gear reduction structure 4. The smooth power after reduction and torque increase is transmitted to the rocker arm 5 through the planetary gear 44, causing the movable seat 6 to gently and regularly reciprocate, thereby achieving automatic rocking of the entire stroller.

[0038] Compared with existing technologies, this embodiment fundamentally solves the problems of strong swaying impact and high noise caused by traditional eccentric wheel transmission by adopting a planetary gear reduction structure, achieving highly stable and quiet gentle swaying. At the same time, the integrated compact design with built-in battery, the quick locking and quick-release design of the clamping structure, and the highly versatile fixing method together give this device extremely high portability, ease of use, and wide applicability, significantly improving the user experience.
