Description

Technical Field

[0001] This utility model relates to the field of children's products technology, and in particular to an infant care device. Background Technology

[0002] For families with infants and toddlers, there is a great need for parents who can both care for their children and have time to work or do housework, so placing their children on a rocking baby care device has become a significant demand.

[0003] Existing rocking infant care equipment generally includes a base, a rocking arm, and a support frame. One end of the rocking arm is pivotally connected to the base via a first pivot, and the other end of the rocking arm is pivotally connected to a second pivot. The support frame is connected to the second pivot, and the infant can be placed on the support frame. When the rocking arm swings, it drives the support frame to swing. In order to control the angle of the support frame's swing, a groove is set on the base, and a roller is eccentrically set on the second pivot. The roller is engaged in the groove. When the rocking arm swings, the roller moves in the groove, thereby controlling the angle of rotation of the second pivot relative to the rocking arm, and thus controlling the angle of the support frame's swing. Furthermore, to enable the support frame to have multiple swing modes, the slide is pivotally connected to the base, and a mechanism for adjusting the state of the slide is also provided. For example, in Chinese patent CN117530564A, an infant high chair has an adjustment switch that swings around the pivot point between the slide and the base for adjustment. If the adjustment switch is located on the outside of the side wall of the shell, when the shell is not circular, or when the center of curvature of the shell and the pivot point between the slide and the base do not coincide or are not close, it is difficult for the adjustment switch to fit well with the outside of the side wall of the shell when adjusting different modes. In order to avoid the space required for the adjustment switch, the adjustment switch needs to maintain a large gap with the shell, which can easily lead to dust entering the shell and is also unsightly. Utility Model Content

[0029] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0030] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0032] See Figures 1 to 9This embodiment discloses an infant care device, including a housing 1, a base 2, a support frame 3, a swing arm 4, a first rotating shaft 5, a second rotating shaft 6, a limiting member 7, a mating member 8, a mode conversion mechanism 9, and a locking / unlocking mechanism 10. The base 2 is used to support the child on the ground. One end of the swing arm 4 is pivotally connected to the base 2 via the first rotating shaft 5, allowing the swing arm 4 to swing relative to the base 2 around the axis of the first rotating shaft. The base 2 supports the swing arm 4. The second rotating shaft 6 is pivotally connected to the other end of the swing arm 4 and swings with the swing arm 4. The support frame 3 is connected to one end of the second rotating shaft 6, and the swing arm 4 supports the support frame 3 via the second rotating shaft. The support frame 3 is used to carry an infant, so that when the swing arm 4 swings, it can drive the support frame. The frame 3 swings to soothe or entertain infants; the limiting member 7 is connected to the other end of the second rotating shaft 6, and the mating member 8 is installed on the base 2. Specifically, the mating member 8 is pivotally connected to the fourth rotating shaft 22 of the base 2. Of course, the fourth rotating shaft 22 can also be set on the mating member 8 and rotate relative to the base 2. The mating member 8 can rotate and change position relative to the base 2 to switch different swing modes. The limiting member 7 and the mating member 8 cooperate, and the limiting member 7 can move relative to the mating member 8. When the second rotating shaft 6 swings with the swing arm 4, the limiting member 7 moves relative to the mating member 8 to control the angle of rotation of the second rotating shaft 6 relative to the swing arm 4, thereby controlling the angle of the support frame 3 when it swings. This is the angle control during the swing process.

[0033] Preferably, the housing 1 is connected to the base 2, and the housing 1 encloses the swing arm 4, the first rotating shaft 5, the limiting member 7, and the mating member 8. The side wall of the housing 1 has a through-hole 11. The mode conversion mechanism 9 is connected to the mating member 8, and the mode conversion mechanism 9 is used to drive the mating member 8 to change position, thereby switching between different swing modes. The locking and unlocking mechanism 10 is disposed between the mode conversion mechanism 9 and the base 2, and the locking and unlocking mechanism 10 is used to lock or unlock the position of the mating member 8, so that the mating member 8 is fixed in different swing modes, allowing the support frame 3 to... The mechanism performs a swinging motion; wherein, the mode conversion mechanism 9 includes a first rotating member 91, a second rotating member 92, and an adjustment switch 93. The first rotating member 91 is pivotally connected to the mating member 8, and the pivot point between the first rotating member 91 and the mating member 8 is offset from the pivot point between the mating member 8 and the base 2. One end of the second rotating member 92 is pivotally connected to the first rotating member 91, and the pivot point between the second rotating member 92 and the first rotating member 91 is offset from the pivot point between the first rotating member 91 and the mating member 8. The other end of the second rotating member 92 extends through the through-hole 11 and is connected to the adjustment switch 93.

[0034] It should be noted that the specific fit between the limiting member 7 and the mating member 8 is known, and the innovation of this utility model does not lie in the specific fit between the limiting member 7 and the mating member 8. Therefore, the specific structure between the limiting member 7 and the mating member 8 is not limited here. For ease of understanding, one example of the limiting member 7 and the mating member 8 is as follows: the limiting member 7 includes a roller 71, which is offset from the pivot point between the second rotating shaft 6 and the swing arm 4, and the mating member 8 includes a groove 81 in which the roller 71 fits.

[0035] It should be noted that gravity can be used to make the swing arm 4 swing freely, or as... Figure 2 , Figures 5 to 7 The swing arm 4 is driven to swing electrically. The innovation of this utility model does not lie in the power source of the swing arm 4, so the specific structure of how to drive the swing arm 4 to swing is not limited here.

[0036] It should be noted that in other examples, the mating part 8 can also slide along a preset track on the base 2, and when the mating part 8 is in different positions, it corresponds to different swing modes; or, the mating part 8 can also be movably connected to the base 2 in other ways, so that the mating part 8 is in different positions and corresponds to different swing modes respectively.

[0037] In the above scheme, when it is necessary to switch between different swing modes, after unlocking, the second rotating component 92 is driven by the adjustment switch 93, the second rotating component 92 drives the first rotating component 91, and the first transmission component drives the mating component 8 to move relative to the base 2, thereby changing the position of the mating component 8. When the swing arm 4 swings and drives the support frame 3 to swing, the mating component 8, whose position has changed, will control the support frame 3 to produce a new angle change through the limiting component 7, thereby switching to different swing modes. Among them, since the second rotating component 92 is pivotally connected to the first rotating component 91, and the first transmission component is pivotally connected to the mating component 8, compared with the prior art, the torsional movement of the second rotating component 92 and the adjustment switch 93 is free relative to the mating component 8 and is not limited to a specific trajectory by the mating component 8 alone. This allows the position of the adjustment switch 93 to freely change relative to the housing 1, keeping the gap between the adjustment switch 93 and the housing 1 within a small range or close. The adjustment switch 93 can move more closely relative to the outside of the housing 1, making it less likely for dust to enter the housing 1 through the opening 11 on the housing 1, and the overall appearance is more aesthetically pleasing.

[0038] See Figure 3 and Figure 4Preferably, a stop 921 is provided on the second rotating member 92. The stop 921 is located inside the housing 1. The stop 921 and the regulating switch 93 are clamped on the inner and outer sides of the housing 1. In this way, by using the stop 921 to abut against the inner side of the housing 1, the distance that the other end of the second rotating member 92 extends outward from the opening 11 can be limited, so that the regulating switch 93 is kept in contact with the outer side of the housing 1, improving the sealing performance and the stability of the regulating switch 93.

[0039] See Figures 5 to 9 In this embodiment, locking or unlocking is achieved through the cooperation between the first rotating member 91 and the base 2. The first rotating member 91 slides along the pivot axis between the first rotating member 91 and the mating member 8. The locking / unlocking mechanism 10 includes a first insertion part and three spaced-apart second insertion parts. The first rotating member 91 has the first insertion part, and the base 2 has the second insertion parts. The first insertion parts and the second insertion parts are engaged to lock or disengaged to unlock. Of course, the placement of the first and second insertion parts can be interchanged; for example, the first insertion part can be located on the base 2, and the second insertion parts can be located on the first rotating member 91. The number of second insertion parts can also be two, four, five, etc., corresponding to different swing patterns. The specific number of second insertion parts is not limited here.

[0040] Preferably, one end of the first rotating member 91 is provided with a corresponding third rotating shaft 911 and an auxiliary shaft 912. The third rotating shaft 911 and the auxiliary shaft 912 are arranged coaxially, with the third rotating shaft 911 located below and the auxiliary shaft 912 located above. The mating member 8 is provided with a third shaft hole 82, a clearance groove 85, and a guide member 83. The third shaft hole 82 passes through one end of the mating member 8 vertically. The third rotating shaft 911 is rotatably disposed in the third shaft hole 82 and can slide axially. The guide member 83 is detachably connected to the mating member 8 by means of screws or rivets, etc. The guide member 83 is located above the third shaft hole 82. The guide member 83 is provided with an auxiliary hole 84 corresponding to the third shaft hole 82. The third shaft hole 82 and the auxiliary hole 84 are also arranged coaxially. Similarly, the auxiliary shaft 912 passes through the auxiliary hole 84 and can also be rotatably disposed in the auxiliary hole 84 and can slide axially. The base 2 is provided with three The three insertion holes 21 are arranged in an arc-shaped interval around the pivot point between the mating member 8 and the base 2, since the mating member 8 is pivotally connected to the base 2. One end of the third rotating shaft 911 is used as the first insertion part, and the insertion hole 21 is used as the second insertion part. One end of the third rotating shaft 911 can be slidably inserted into the insertion hole 21 to form a lock or disengage from the insertion hole 21 to form an unlock. The clearance groove 85 is connected to the third shaft hole 82. The clearance groove 85 opens towards the mating member 8 to accommodate the first rotating member 91. One end of the first rotating member 91 is located in the clearance groove 85. The clearance groove 85 restricts the first rotating member 91 from swinging relative to the mating member 8 within a preset range.

[0041] To ensure that one end of the third rotating shaft 911 remains locked in the insertion hole 21 under normal conditions, an elastic element 94 is also included. One end of the elastic element 94 is connected to the mating part 8, and the other end of the elastic element 94 is connected to the first rotating part 91. The elastic element 94 provides elastic force to keep one end of the third rotating shaft 911 inserted into the insertion hole 21. Specifically, based on the presence of the guide part 83 and the auxiliary shaft 912, the elastic element 94 includes a spring, which is sleeved on the auxiliary shaft 912. One end of the spring abuts against one end of the first rotating part 91, and the other end of the spring abuts against the guide part 83. Thus, the installation of the elastic element 94 is achieved by using the guide part 83 and the auxiliary shaft 912. Its structure is simple and easy to assemble.

[0042] To limit the adjustment switch 93 to different positions on the housing 1 in different swing modes, see [reference needed]. Figure 3 and Figure 4 The port 11 has three spaced grooves 12. When one end of the third rotating shaft 911 is slidably inserted into the socket 21, the second rotating member 92 is embedded in the groove 12 and fixed. In this way, the current swing mode can be intuitively determined by adjusting the position of the switch 93. Moreover, the grooves 12 also limit the second rotating member 92 to prevent accidental unlocking and potential safety hazards. The number of grooves 12 is equal to the number of sockets 21. When the number of sockets 21 changes, the number of grooves 12 also changes accordingly.

[0043] In the above scheme, the significance of using one end of the third rotating shaft 911 as the first insertion part is that the positions of the first insertion part and the second insertion part are not affected by the rotation of the first rotating member 91 relative to the mating member 8, but are affected by the rotation of the mating member 8 relative to the base 2. That is to say, when the position of the mating member 8 relative to the base 2 is determined, no matter how much the first rotating member 91 rotates relative to the mating member 8, the position of the third rotating shaft 911 relative to the base 2 is determined, that is, the position of the first insertion part relative to the base 2 is determined, which facilitates the alignment of the position during the locking operation. Moreover, the locking and unlocking mechanism 10 is integrated into the mode conversion mechanism 9, resulting in a simple overall structure and low cost.

[0044] In the above scheme, the purpose of setting the guide member 83 is to guide the sliding of the first rotating member 91 on the mating member 8, so that the sliding action of the first rotating member 91 is stable; it also facilitates the assembly between the first rotating member 91 and the mating member 8. During assembly, the third rotating shaft 911 is first inserted into the third shaft hole 82 from top to bottom, the elastic member 94 is fitted into the auxiliary shaft 912, and then the guide member 83 is installed so that the auxiliary hole 84 fits into the upper end of the auxiliary shaft 912 and compresses the elastic member 94. In this way, the installation of the first rotating member 91 is completed, and the assembly is convenient and simple.

[0045] It should also be noted that, regarding the locking and unlocking mechanism 10, an insertion hole 21 can be provided at the end of the third rotating shaft 911, and at least two protrusions can be provided on the base 2. The locking or unlocking can be achieved by the insertion and engagement of the insertion hole 21 on the third rotating shaft 911 and the protrusions on the base 2, thereby realizing the position of the locking or unlocking mating part 8; or, the locking and unlocking mechanism 10 can also adopt other known methods, as long as they can realize the function of locking or unlocking the position of the mating part 8, which will not be elaborated here.

[0046] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
