[0044] In combination with Figures 1-5 As shown in the drawings, the utility model provides a kind of baby swing bed gear box device, comprising:

[0045] X-axis movement mechanism and Y-axis movement mechanism are respectively used to control the movement of baby swing bed in X-axis and Y-axis direction;

[0046] Photoelectric sensor is installed on the track of X-axis and Y-axis movement, for real-time acquisition of movement data;

[0047] A grating is also installed on the track of the X-axis and Y-axis movement, which is used in cooperation with the photoelectric sensor to improve the accuracy of position feedback.

[0048] A central processor is used to process the movement data collected by the photoelectric sensor and the grating, and control the movement speed and position of the X-axis and Y-axis through a preset graphic trajectory.

[0049] The X-axis movement mechanism and the Y-axis movement mechanism each comprise a box body 1, a motor 2, a worm 3, a first gear 4, a secondary gear 5, a second gear 6, and a swing arm 7.

[0060] The principle of the utility model is as follows:

[0061] Motion Control: The X-axis and Y-axis motion mechanisms are responsible for controlling the motion of the baby swing bed in two perpendicular directions within the horizontal plane. Each motion mechanism is driven by a motor 2, which transmits power to the swing arm 7 through a transmission system composed of a worm 3, a first gear 4, a secondary gear 5, and a second gear 6, and then moves the swing bed in the set direction. According to the design, one end of the swing arm 7 is installed on the second gear 6 (it can be the center position or a position deviating from the center), and the other end is connected to the swing bed, so that the swing bed can perform complex motion patterns such as sine wave, ellipse, or polygon trajectory according to the pre-set trajectory.

[0063] Intelligent Adjustment: The central processor receives and processes data from photoelectric sensors and gratings, and controls the motion speed and position of X-axis and Y-axis according to the pre-set graphical trajectory, ensuring that the motion of the swing bed meets the expectations. In addition, the pressure sensor array integrated under the carrying surface of the swing bed can detect the weight distribution of the baby and feed the information back to the central processor, so as to dynamically adjust the motion pattern of the swing bed and optimize the comfort and safety of the baby.

[0064] Low-noise operation: In order to reduce the noise generated during operation, the worm 3 adopts a helical tooth structure, and a 0.05-0.1mm thick polytetrafluoroethylene noise reduction coating is applied on its meshing surface.

[0066] In summary, the baby swing bed gear box device realizes multi-dimensional, accurate and quiet control of the baby swing bed through precise mechanical structure design, intelligent control system and humanized design concept, providing a safe and comfortable sleep environment for the baby.
