AI Technical Summary
Existing infant care equipment suffers from poor stability due to the wobbling of the seat frame caused by the gap between the rollers and the slide.
By setting an eccentric pivot connection between the slide and the mating part in the infant care equipment, the abutment part on the slide rolls or slides against the side wall of the mating part, controlling the rotation angle of the second rotating shaft relative to the swing arm, increasing the tightness between the slide and the mating part, and thus preventing the seat frame from shaking.
The stability of the seat frame of the infant care equipment has been improved when it swings, ensuring the safety and comfort of infants and children during use.

Abstract
Description
Technical Field
[0001] This invention relates to the field of infant and child products technology, and in particular to an infant and child 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 infant care equipment, such as infant rockers, generally includes a base, a swing arm, and a seat frame. One end of the swing arm is pivotally connected to the base via a first pivot, and the other end is pivotally connected to a second pivot. The seat frame is connected to the second pivot. When the swing arm swings, it drives the seat frame to rock. To control the angle of the seat frame's rocking motion, a groove is provided on the base, and a roller is eccentrically positioned on the pivot. The roller engages with the groove. When the swing arm swings, the roller moves within the groove, and one sidewall of the groove applies force to the roller, thereby controlling the angle of rotation of the second pivot relative to the swing arm, and thus controlling the angle of the seat frame's rocking motion. This single roller embedded in the groove means that during rocking, the roller rolls against one sidewall of the groove. However, a certain gap is created between the roller and the other sidewall of the groove, causing the seat frame to wobble and resulting in poor stability. Summary of the Invention
[0004] In order to overcome at least one of the defects described in the prior art, the present invention provides an infant care device with a seat frame that does not wobble when rocking, and has high stability.

[0043] 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.
[0044] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., 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 invention 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 invention.
[0045] 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 in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0046] See Figures 1 to 4This invention discloses an infant care device, comprising: a base 1, a seat frame 2, a first rotating shaft 3, a swing arm 4, a second rotating shaft 5, a sliding seat 6, and a mating component 7. The base 1 is used to support the device on the ground. One end of the swing arm 4 is pivotally connected to the base 1 via the first rotating shaft 3. The swing arm 4 can swing relative to the base 1 around the axis of the first rotating shaft 3. The base 1 supports the swing arm 4. The second rotating shaft 5 is pivotally connected to the other end of the swing arm 4 and swings together with the swing arm 4. The seat frame 2 is connected to one end of the second rotating shaft 5. The swing arm 4 supports the seat frame 2 via the second rotating shaft 5. The seat frame 2 is used to carry an infant, so that when the swing arm 4 swings, it can drive the seat frame 2 to swing, thereby soothing or entertaining the infant.
[0047] The slide 6 is pivotally connected to the other end of the second rotating shaft 5, and the pivot axis between the slide 6 and the second rotating shaft 5 is offset from the pivot axis between the second rotating shaft 5 and the swing arm 4. The mating part 7 is disposed on the base 1. When the second rotating shaft swings with the swing arm 4, the slide 6 can move relative to the mating part 7, thereby controlling the angle of rotation of the second rotating shaft relative to the swing arm 4, and thus achieving the purpose of controlling the angle of the seat frame 2 when it swings. The mating part 7 has a first side wall 71 and a second side wall 72. The first side wall 71 and the second side wall 72 are arranged opposite to each other and are used to guide the movement of the slide 6. The slide 6 has at least three abutting parts 61, wherein at least two abutting parts 61 are arranged at intervals and abut against one of the first side wall 71 and the second side wall 72, and the remaining at least one abutting part 61 abuts against the other of the first side wall 71 and the second side wall 72.
[0048] In the above scheme, the slide 6 is eccentrically pivoted to the second rotating shaft. At least two abutting parts 61 arranged at intervals in the slide 6 abut against one of the guiding side walls of the mating parts 7, and at least one other abutting part 61 abuts against another guiding side wall of the mating parts 7. That is to say, during the process of guiding the slide 6 to move by the two side walls of the mating parts 7, the slide 6 abuts against the two opposite side walls of the mating parts 7 through at least three abutting parts 61, forming at least three abutting points on both sides, thereby increasing the tightness of the fit between the slide 6 and the mating parts 7, so that the seat frame 2 will not wobble when it swings, thus improving stability.
[0049] It is understandable that the abutting part 61 may also be provided in four, five, six, etc., and the multiple abutting parts 61 are divided into two groups to abut against the first side wall 71 and the second side wall 72 respectively.
[0050] See Figure 5 and Figure 6In order to make the pivot axis between the slide 6 and the second rotating shaft 5 deviate from the pivot axis between the second rotating shaft 5 and the swing arm 4, specifically, the second rotating shaft 5 includes a shaft body 51 and a transition body 52. One end of the shaft body 51 and the transition body 52 are fixedly connected. The shaft body 51 is used to pivotally connect to the other end of the swing arm 4. A third rotating shaft 8 is provided between the other end of the transition body 52 and the slide 6. The third rotating shaft 8 can be fixedly connected to the transition body 52 and pivotally connected to the slide 6, or the third rotating shaft 8 can be pivotally connected to the transition body 52 and fixedly connected to the slide 6, or the third rotating shaft 8 can be pivotally connected to both the transition body 52 and the slide 6, so that the slide 6 can rotate relative to the transition body 52. The shaft body 51 and the third rotating shaft 8 are preferably parallel and spaced apart.
[0051] The contact portion 61 of the present invention can be preferably implemented in at least two of the following ways (Solution 1 and Solution 2 below).
[0052] Option 1: Using rollers 602 as abutment parts 61. Specifically, the slide 6 includes a seat body 601 and at least three rollers 602. The rollers 602 are disposed on the seat body 601 and serve as abutment parts 61 for rolling abutment against the first side wall 71 or the second side wall 72. That is, at least two rollers 602 are arranged at intervals and abut against one of the first side wall 71 and the second side wall 72, while at least one remaining roller 602 abuts against the other of the first side wall 71 and the second side wall 72. More specifically, four rollers 602 are preferred, divided into two groups, with two rollers 602 in each group arranged at intervals. The two rollers 602 in one group roll abut against the first side wall 71, and the two rollers 602 in the other group roll abut against the second side wall 72. Of course, the number of rollers 602 can also be five, six, etc.
[0053] Rollers 602 are used as abutment parts 61 to form rolling abutment, and each roller 602 only rolls against one side wall. While ensuring a tight fit, it also helps to reduce friction, making the seat frame 2 swing more smoothly and effortlessly.
[0054] Option 2: Using ribs 604 as abutment parts 61. Specifically, the slide 6 includes a seat body 601 and at least three ribs 604. The ribs 604 are disposed on the seat body 601 and serve as abutment parts 61 for sliding abutment against the first sidewall 71 or the second sidewall 72. More specifically, four ribs 604 are preferred, divided into two groups, with two ribs 604 in each group arranged at intervals. The two ribs 604 in one group roll against the first sidewall 71, and the two ribs 604 in the other group roll against the second sidewall 72. Of course, the number of ribs 604 can also be five, six, etc.
[0055] The preferred embodiments of the mating component 7 of the present invention can be at least the following two (Solution 3 and Solution 4 below).
[0056] Option 3: The mating component 7 includes a slide rail 701, which guides the movement of the slide block 6. In this case, the two opposite outer sidewalls of the slide rail 701 serve as the first sidewall 71 and the second sidewall 72. Depending on the design requirements, the slide rail 701 can be arc-shaped, straight, or wavy. The extension trajectory of the slide rail 701 is not limited here.
[0057] Option 4: The mating part 7 includes a slide groove 702, which guides the movement of the slide block 6. In this case, the two opposing inner sidewalls of the slide groove 702 serve as the first sidewall 71 and the second sidewall 72. Similarly, depending on the design requirements, the slide groove 702 can be arc-shaped, straight, or wavy. The extension trajectory of the slide groove 702 is not limited here.
[0058] In addition, regarding the first sidewall 71 and the second sidewall 72, the surfaces of the first sidewall 71 and the second sidewall 72 can be flat, which can be considered as Scheme 5; the first sidewall 71 and / or the second sidewall 72 can also be provided with a recessed groove 73, the recessed groove 73 extends along the extension direction of the first sidewall 71 and / or the second sidewall 72, the abutting part 61 is embedded in the recessed groove 73 and slides or rolls relative to the recessed groove 73, the recessed groove 73 also provides support for the abutting part 61 to prevent the slide 6 from sinking, thereby avoiding the sinking feeling when the seat frame 2 is under load, which can be considered as Scheme 6.
[0059] See Figure 10 or Figure 15 or Figure 20 or Figure 25 Preferably, the recessed groove 73 has a first inclined surface for abutting against the abutting portion 61 to provide support, and the abutting portion 61 has a second inclined surface that matches the first inclined surface, so that when the seat frame 2 is under load and the recessed groove 73 provides support, the support force provided by the recessed groove 73 is inclined. Specifically, the first inclined surface is preferably the side wall of the recessed groove 73. Correspondingly, when the roller 601 is used as the abutting portion 61, the second inclined surface is provided around the roller 601 so that the shape of the roller 601 matches the shape of the recessed groove 73; when the rib 604 is used as the abutting portion 61, the second inclined surface is provided on the side of the rib 604 so that the shape of the rib 604 matches the shape of the recessed groove 73.
[0060] More preferably, the cross-sectional shape of the recessed groove 73 can be conical or trapezoidal, so that the sidewall of the recessed groove 73 is inclined, thus having a first inclined surface.
[0061] The above-mentioned solutions can be combined and linked.
[0062] For combinations of Schemes 1, 3, and 5, please refer to the appendix. Figures 5 to 7 The first embodiment is shown. This first embodiment is also shown in Figures 1 to 4 As shown in the attached diagram.
[0063] For combinations of Options 1, 3, and 6, please refer to the appendix. Figures 8 to 10 The second implementation shown.

[0070] It is understandable that there are other possible combinations, which will not be listed here.
[0071] Furthermore, based on the aforementioned use of slide rail 701 to guide the movement of slide block 6, it is also preferable that slide block 6 is provided with a through clearance groove 603, slide rail 701 is embedded in clearance groove 603, and abutment part 61 at least partially protrudes from the inner wall of clearance groove 603 and abuts against the outer wall of slide rail 701. Specifically, clearance groove 603 is provided in seat body 601, clearance groove 603 extends through two opposite sides of seat body 601 along the guiding direction of slide rail 701, and clearance groove 603 also extends through the lower side of seat body 601, thereby facilitating slide rail 701 to be embedded in clearance groove 603; when roller 602 is used as abutment part 61, roller 602 is pivotally connected to seat body 601 by pin, and seat body 601 is provided with mounting groove corresponding to the position of roller 602, communicating with clearance groove 603, roller 602 is located in mounting groove The roller 602 protrudes from the inner wall of the clearance groove 603 to abut against the outer wall of the slide rail 701. This arrangement provides better support for the roller 602 and avoids the permanent deformation or elastic deformation of the pin that is prone to cause gaps and wobbling when the roller 602 is installed by using a downwardly protruding pin. When a rib 604 is used as the abutment part 61, the rib 604 can be set on the inner wall of the clearance groove 603 and protrude so that the rib 604 abuts against the outer wall of the slide rail 701.
