This invention discloses an infant rocker, including a support frame, a bassinet, a sliding mechanism, and a drive mechanism. The support frame has two vertically arranged support rods at its upper part, connected by a guide shaft. The sliding mechanism includes a connecting seat, a housing, and rolling elements. The housing is fixed to the connecting seat, and both ends of the housing have through holes. The guide shaft passes through both through holes. At least three rolling elements are evenly distributed around the guide shaft inside the housing, and the rolling elements abut against the outside of the guide shaft. The drive mechanism is located between the connecting seat and the support rods to drive the connecting seat to move back and forth along the axial direction of the guide shaft. The bassinet is fixed to the side of the connecting seat away from the housing. The bassinet in this application swings more smoothly and is less prone to large-amplitude shaking due to impacts. Simultaneously, due to the simple structure of the sliding mechanism, it occupies relatively little space, which helps to reduce the size of the infant rocker.

Description

Technical Field

[0001] This invention relates to the field of infant care equipment technology, and in particular to an infant rocker. Background Technology

[0002] Patent document CN217390331U discloses an automatic rocking device and a crib, which includes a base frame, a rocking mechanism, and a bassinet seat. The rocking mechanism enables the bassinet seat to rock automatically, thereby reducing the burden on parents.

[0003] The swing mechanism includes a drive base, a transmission assembly, and a first boom. The transmission assembly includes a driver, a first gear, a second gear, a third gear, a fourth gear, and a fifth gear, which drive the first boom to swing through the transmission of multiple gears, thereby realizing the swing of the sleeping basket seat.

[0004] Although the aforementioned rocking mechanism can achieve automatic rocking of the bassinet seat, its structure is too complex, resulting in excessive volume, difficulty in installation, and poor stability. Summary of the Invention

[0005] Therefore, the purpose of this invention is to provide a baby rocker with a simple and stable structure and a small size.

[0006] An infant rocker includes a support frame, a bassinet, a sliding mechanism, and a drive mechanism. Two support rods are vertically arranged on the upper part of the support frame, and a guide shaft is connected between the two support rods.

Therefore, they may vary depending on their location and usage. Consequently, these or other directional terms should not be interpreted as restrictive.

[0028] The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of embodiments consistent with some aspects of this disclosure.

[0029] The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. The singular forms “a,” “the,” and “the” as used herein are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any and all possible combinations of one or more of the associated listed items.

[0030] like Figures 1 to 5 As shown, the present invention relates to an infant rocker, including a support frame 1, a bassinet 2, a sliding mechanism 3, and a drive mechanism 4. The support frame 1 has two vertical support rods 11 on its upper part, and the two support rods 11 are connected to each other by a guide shaft 12.

[0031] The sliding mechanism 3 includes a connecting seat 31, a housing 32, and rolling elements. The housing 32 is fixed to the connecting seat 31. Both ends of the housing 32 are provided with through holes. The guide shaft 12 passes through the two through holes. At least three rolling elements are evenly distributed inside the housing 32 around the guide shaft 12, and the rolling elements abut against the outside of the guide shaft 12 so that when the housing 32 moves relative to the guide shaft 12, the rolling elements roll on the guide shaft 12.

[0032] The drive mechanism 4 is located between the connecting seat 31 and the support rod 11 to drive the connecting seat 31 to move back and forth along the axial direction of the guide shaft 12.

[0033] The sleeping basket 2 is fixed to the side of the connecting seat 31 away from the housing 32.

[0034] In this invention, when the driving mechanism 4 drives the sliding mechanism 3 to move back and forth, the rolling element can roll back and forth along the guide shaft 12, thereby allowing the connecting seat 31 to move smoothly along the guide shaft 12, so that the swing of the bassinet 2 is more stable and less prone to large-amplitude shaking due to impact; at the same time, since the sliding mechanism 3 has a simple structure, it occupies relatively little space, which is conducive to reducing the volume of the baby rocker.

[0035] In this embodiment, two guide shafts 12 are connected to each other between the two support rods 11. The upper and lower parts of the connecting seat 31 are provided with housings 32. The two guide shafts 12 are inserted into the two housings 32 in a one-to-one correspondence, so as to provide stable guiding sliding in the upper and lower parts of the connecting seat 31, so as to make the bassinet 2 swing more smoothly.

[0036] The housing 32 has rolling elements at both ends. That is, at least three rolling elements are provided at one end of the housing 32 along the circumferential direction, and at least three rolling elements are also provided at the other end of the housing 32 along the circumferential direction, so as to make the swing of the bassinet 2 more stable.

[0037] In this embodiment, at least three receiving grooves 33 are provided at the end of the housing 32 along the circumferential direction, and the rolling element is provided in each of the at least three receiving grooves 33.

[0038] The two opposite sidewalls of the receiving groove 33 are provided with connecting grooves 34 along the length direction. The rolling element includes a roller 35 and a rotating shaft 36. The rotating shaft 36 passes through the roller 35 and the roller 35 can rotate around the rotating shaft 36. The two ends of the rotating shaft 36 extend into the two connecting grooves 34 respectively.

[0039] Both ends of the housing 32 are open, and both ends of the housing 32 are covered with a cover 37. Both covers 37 are provided with through holes. At least three sets of abutment posts are evenly distributed on the inner side of the cover 37 around the through holes. The at least three sets of abutment posts correspond one-to-one with at least three receiving grooves 33. Each set of abutment posts includes two abutment posts 38. The two abutment posts 38 extend into the two connecting grooves 34 on both sides of the receiving groove 33 and abut against both ends of the rotating shaft 36.

[0040] Therefore, during assembly, the roller 35 is placed in the receiving groove, and the two ends of the rotating shaft 36 are respectively inserted into the two connecting grooves 34. Then, the cover 37 is covered over the opening of the housing 32 and locked with screws so that the abutment post 38 on the inner side of the cover 37 can hold the rotating shaft 36 in place, ensuring the stability of the position of the rotating shaft 36 and the roller 35 for smooth sliding.

[0041] In this embodiment, the driving mechanism 4 includes a drive motor 41, a rotating arm 42, and a connecting arm 43. The drive motor 41 is fixed on the connecting seat 31. The output shaft of the drive motor 41 is fixed to one end of the rotating arm 42. The other end of the rotating arm 42 is rotatably connected to the connecting arm 43. The end of the connecting arm 43 away from the rotating arm 42 is rotatably connected to a support rod 11. Thus, when the drive motor 41 drives the rotating arm 42 to rotate, it can drive the connecting seat 31 to swing back and forth along the guide shaft 12.

[0042] In this embodiment, the upper part of the connecting seat 31 away from the housing 32 is provided with a raised part 39, and the side of the sleeping basket 2 is provided with a mounting seat 21. The mounting seat 21 is provided with a hanging hole that can be hung on the raised part 39 so as to install the sleeping basket 2 on the connecting seat 31.

[0043] In this embodiment, the lower part of the support bracket 1 is provided with wheels 13 to facilitate the movement of the baby rocker.

[0044] In summary, compared with the prior art, the baby rocker of this application has a simpler structure, smaller size, stronger resistance, and smoother and more stable rocking motion.

[0045] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
