Description

Technical Field

[0001] This utility model relates to the field of rocking bed technology, and in particular to a novel adjustable electric rocking bed for children. Background Technology

[0002] Baby rocking cradles are commonly used auxiliary tools in infant care, used to soothe babies and help them fall asleep.

[0003] Most existing products lack automatic rocking functionality, relying entirely on caregivers to manually apply external force to push the rocker. This not only consumes the caregiver's energy and is difficult to maintain for extended periods, but also fails to provide sustained comfort at night or when the caregiver needs to leave briefly. Furthermore, the rocker lacks an effective rocking position locking mechanism. When the rocker needs to be placed still or stored, it will swing freely, making it difficult to stably fix at a specific angle or position, resulting in inconvenient operation and certain safety hazards.

[0035] Example 2

[0036] Reference Figure 1 , Figures 5-7 This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that: the support leg 8 includes a retractable arm 81 and a storage arm 83, and the retractable arm 81 is located inside the storage arm 83 and is snapped into the storage arm 83. A fixing frame 85 is fixed inside the retractable arm 81 near the storage arm 83. Mounting cylinders 84 are fixed at both ends of the fixing frame 85. An elastic element is installed inside the mounting cylinder 84. The elastic element is a spring or a rubber column. A locking block 86 is fixed to the outward end of the elastic element, and the end of the locking block 86 away from the elastic element is set in a semi-circular ball end. A column hole for the locking block 86 to pass through is opened at the position of the retractable arm 81 opposite to the two locking blocks 86. A fixing hole 88 for snapping into the locking block 86 is opened at the end of the storage arm 83 near the retractable arm 81.

[0037] A retaining sleeve 82 is sleeved on one end of the storage arm 83 near the retracting arm 81. A pressing block 87 is provided on the periphery of the retaining sleeve 82 and at the position opposite to the fixing hole 88. When the pressing block 87 is pressed, it contacts the locking block 86.

[0038] The support leg 8 also includes a mounting block 89 installed inside the housing 1, and two rotating shafts 811 that rotate inside the housing 1 and are located on both sides of the mounting block 89. The end of the retractable arm 81 away from the storage arm 83 is sleeved on the rotating shaft 811. A limiting shaft 813 is fixed to the end face of the mounting block 89 near the retractable arm 81. Two arm sleeves 810 are sleeved on the limiting shaft 813, and the arm sleeves 810 have vertical cavities for the limiting shafts 813 to pass through. The arm sleeves 810 are sleeved on the end of the retractable arm 81 near the mounting block 89, and the arm sleeves 810 have reserved holes for the rotating shafts 811 to pass through.

[0039] Both arm sleeves 810 have a mounting base 812 installed at the bottom of their opposite sides. One mounting base 812 has two slots 1 on the side away from the arm sleeve 810, and the other mounting base 812 has three slots 2 on the side away from the arm sleeve 810. Slots 1 and 2 are staggered, and the two mounting bases 812 are connected by slots 1 and 2. The retractable arm 81 rotates around the rotating shaft 811, rotating both retractable arms 81 on the same side towards the center. When the two retractable arms 81 on the same side are in a vertical position, the two mounting bases 812 are in a locked state, bringing the two retractable arms 81 together and fixing them, further folding the support leg 8.

[0040] During use, when the support leg 8 needs to be retracted, the compression block 87 is pressed. The compression block 87 applies pressure to the locking block 86 in the direction of the fixing frame 85. The locking block 86 compresses the elastic element, causing the locking block 86 to disengage from the fixing hole 88. At this time, the retractable arm 81 can be quickly retracted into the storage arm 83.

[0041] The remaining structure is the same as that in Example 1.

[0042] Based on embodiments 1-2, the working principle of this utility model is as follows: When the retractable arm 81 is retracted into the storage arm 83, the semi-circular ball end of the mounting cylinder 84 abuts against the inner wall surface of the storage arm 83 and compresses the elastic element, pulling the retractable arm 81 out from the storage arm 83. When the locking block 86 passes through the fixing hole 88, the locking block 86 releases the compression on the elastic element. Under the buffering effect of the elastic element, the mounting cylinder 84 enters the fixing hole 88 and fixes the retractable arm 81 and the storage arm 83 together, thus unfolding the support leg 8.

[0043] When the rotary switch 3 is in the unlocked state, the locking pin 27 is not in contact with the limiting hole 13. At this time, the servo motor 15 drives the connecting frame plate 20 to rotate, which in turn drives the rotating sleeve 2, the swing arm 4 and the bed 6 to rotate, realizing the swing state of the bed 6. The rotary switch 3 is driven to rotate clockwise to lock the rotary switch 3. During the rotation of the rotary switch 3, the position of the V-groove 24 is in a state of rotational change. When the V-groove 24 is engaged with the mating edge 17, the rotation of the rotary switch 3 will abut against the mating edge 17 and drive the linkage hollow column 18 to move towards the limiting hole 13. The linkage hollow column 18 compresses the spring 26 and causes the locking pin 27 to enter the locking of the limiting hole 13. At this time, the rotating sleeve 2 is locked, so that the rotating sleeve 2 cannot swing.

[0044] Rotate the knob switch 3 to the unlocked state. Under the elastic reset action of the spring 26, the locking pin 27 moves out of the limit hole 13, restoring the swingable state of the rotating sleeve 2.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
