Description

Technical Field

[0001] The utility model relates to a baby rocking chair frame.

Background Art

[0002] A baby rocking chair is a product for infants and young children to lie on and can perform reciprocating rocking. When the mood of infants and young children fluctuates, the rocking chair imitates the rocking of parents by performing reciprocating rocking movements to provide a spiritual comfort to infants and young children, which helps to calm their emotions. However, current rocking chairs are prone to jamming and pausing during reciprocating rocking, and the noise is relatively large.

[0003] Therefore, the present utility model is precisely produced based on the above deficiencies.

Detailed Embodiment

[0031] The present utility model will be further described below with reference to the drawings:

[0032] Such as Figures 1 to 11As shown in the figure, a baby rocking chair frame includes a bottom support frame 1 for supporting on the ground. The bottom support frame 1 includes an upper housing 11 and a lower housing 12 connected thereto. A fixed seat 2 is provided on the bottom support frame 1. The fixed seat 2 is arranged between the upper housing 11 and the lower housing 12. A movable seat 3 capable of moving horizontally therein is provided in the fixed seat 2. A movable frame 4 capable of moving with it is connected to the movable seat 3. An insertion joint 32 is provided at the upper end of the movable seat 3. A plug-in groove (not shown in the figure) capable of being plugged and matched with the insertion joint 32 is provided on the movable frame 4. Through the plugging and matching of the insertion joint 32 and the plug-in groove, the assembly is convenient. A seat support frame 5 for carrying a seat is connected to the movable frame 4, and a cloth cover can be sleeved on the seat support frame 5 for infants and young children to lie on. A driving mechanism 6 capable of driving the movable seat 3 to move horizontally back and forth is provided between the fixed seat 2 and the movable frame 4. A guiding mechanism is provided between the movable seat 3 and the fixed seat 2. The guiding mechanism includes a guiding column 71 provided on the fixed seat 2. The upper side of the guiding column 71 has a first horizontal plane 71a. The movable seat 3 is sleeved on the guiding column 71. First bearings 721 and second bearings 722 capable of rolling and mating with the first horizontal plane 71a when the movable seat 3 moves horizontally are provided on both sides of the movable seat 3. When the baby rocking chair is working, the driving mechanism 6 drives the movable frame 4 and the movable seat 3 to move horizontally back and forth relative to the fixed seat 2. During this process, the first bearings 721 and second bearings 722 on both sides of the movable seat 3 roll on the first horizontal plane 71a on the upper side of the guiding rod 71, which can make the movable seat 3 move smoothly along the guiding rod 71, and further make the movable frame 4 and the seat support frame 5 swing smoothly, and the noise is small during the moving process.

[0033] As Figure 8 shown, in order to further make the movable seat 3 move smoothly on the guiding rod 71, the lower side of the guiding column 71 has a second horizontal plane 71b. Third bearings 723 and fourth bearings 724 capable of rolling and mating with the second horizontal plane 71b when the movable seat 3 moves horizontally are provided on both sides of the movable seat 3. Therefore, the upper side of the guiding rod 71 cooperates with the first bearings 721 and second bearings 722, and the lower side cooperates with the third bearings 723 and fourth bearings 724, making the movable seat 3 move very smoothly. In this embodiment, the guiding column 71 is a metal column with a square longitudinal section. The first bearings 721, second bearings 722, third bearings 723 and fourth bearings 724 roll on the metal column, and the movement is smooth. The metal column can be an iron column.

[0034] As Figure 9As shown in the figure, the inner side wall of the fixed seat 2 has a first longitudinal plane 21. On both sides of the moving seat 3, there are a fifth bearing 725 and a sixth bearing 726 that can rollingly cooperate with the first longitudinal plane 21 when the moving seat 3 moves horizontally. The outer side wall of the moving seat 3 has a second longitudinal plane 31. On both sides of the fixed seat 2, there are a seventh bearing 727 and an eighth bearing 728 that can rollingly cooperate with the second longitudinal plane 31 when the moving seat 3 moves horizontally. Therefore, when the moving seat 3 moves horizontally, both the front and rear sides of the moving seat 3 are supported and limited, making the movement of the moving seat 3 smoother, more flexible, and with less noise.

[0035] As Figure 9 shown in the figure, both the fixed seat 2 and the moving seat 3 are integrally formed by injection molding, with a simple molding process and low cost. Metal sheets 8 are inserted into both the fixed seat 2 and the moving seat 3. The first longitudinal plane 21 and the second longitudinal plane 31 are formed by the surfaces of the corresponding metal sheets 8. Therefore, the fifth bearing 725, the sixth bearing 726, the seventh bearing 727, and the eighth bearing 728 all rollingly cooperate with the metal sheets 8, being smooth, flexible, and with less noise, avoiding the risk of easy deformation of the plastic caused by long-term rolling cooperation with the plastic and extending the service life of the product.

[0036] On the moving frame 4 and located at the rear side of the moving seat 3, there are two connecting seats 41. On the fixed seat 2, there are a ninth bearing 729 and a tenth bearing 720 that can rollingly cooperate with the lower surface of the connecting seats 41 when the moving seat 3 moves horizontally. The connecting seat 41 includes an injection-molded seat body 411. A iron sheet is provided on the lower side of the seat body 411. The ninth bearing 729 and the tenth bearing 720 are in contact with the lower surface of the iron sheet. Therefore, when the moving seat 3 moves horizontally, the ninth bearing 729 and the tenth bearing 720 also play a supporting role on the rear side of the moving frame 4, making the swinging of the moving frame 4 smooth.

[0037] As Figure 3 、 Figure 5 and Figure 10As shown in the figure, the drive mechanism 6 includes a drive motor 61 fixedly arranged in the moving frame 4. A transmission device 62 is connected to the output shaft of the drive motor 61. A protruding shaft 63 is fixedly connected to the output shaft of the transmission device 62. A connecting rod 64 hinged to both of them is arranged between the protruding shaft 63 and the fixed seat 2. The transmission device 62 includes a first pulley 621 arranged on the output shaft of the drive motor 61. The first pulley 621 is connected to a second pulley 622 through a belt. The second pulley 622 is connected to a worm and worm gear mechanism. The output shaft of the worm and worm gear mechanism is connected to the protruding shaft 63. When the baby rocker works, the drive motor 61 drives the first pulley 621 to rotate. The first pulley 621 drives the second pulley 622 to rotate through the belt, so that the worm and worm gear mechanism rotates, enabling the drive motor 61 to decelerate. And the output shaft of the worm and worm gear mechanism drives the protruding shaft 63 to rotate. The protruding shaft 63 drives the connecting rod 64 to rotate. Also, since the other end of the connecting rod 64 is rotatably connected to the fixed seat 2, when the connecting rod 64 rotates, it will push the drive motor 61, the worm and worm gear mechanism and the moving frame 4 to move reciprocally together. The moving seat 3 also moves reciprocally on the guide rod 71. The entire drive mechanism 6 has a compact structure and reliable and stable driving performance.

[0038] The above has described this embodiment in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiment. Within the scope of knowledge possessed by those of ordinary skill in the technical field, various changes can be made without departing from the gist of the present invention.
