[0054] 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 application belongs. The terminology used in the description herein is for describing particular embodiments only and is not intended to be limiting of the application.

[0055] Embodiment 1

[0056] Referring to Figure 1 and Figure 2 The utility model discloses a kind of foldable storage's baby care equipment, for the baby, it includes: bottom support mechanism 1, two support arms 2, two seat surrounding rods 3, connecting structure 4, second locking mechanism 5, bottom support mechanism 1 can be used to support on ground, two support arms 2 are connected to bottom support mechanism 1, each support arm 2 connects a seat surrounding rod 3, bottom support mechanism 1 supports two support arms 2, two support arms 2 respectively support two seat surrounding rods 3, two seat surrounding rods 3 as the seat frame main component of the baby care equipment.

[0057] Specifically, two support arms 2 are arranged along seat front-back direction, two seat surrounding rods 3 are arranged along seat front-back direction, one end of two support arms 2 is respectively pivoted to the opposite sides of bottom support mechanism, limiting structure 8 that supports arm 2 and bottom support mechanism 1 between is also provided, which limits the folding of support arm 2 downward rotation, the other end of two support arms 2 is respectively pivoted to different seat surrounding rods 3, two seat surrounding rods 3 are connected by connecting structure 4, second locking mechanism 5 is arranged between each support arm 2 and bottom support mechanism 1, the function of second locking mechanism 5 is to lock support arm 2 and bottom support mechanism 1 to form fixed connection or unlock.

[0058] Among them, it can be understood that seat front-back direction refers to the overall length direction after two seat surrounding rods 3 form seat frame or the overall length direction after two seat surrounding rods 3 combine other auxiliary components (such as the upper portion of support arm 2 in the embodiment), and seat left-right direction refers to the overall width direction after two seat surrounding rods 3 form seat frame or the overall width direction after two seat surrounding rods 3 combine other auxiliary components (such as the upper portion and intermediate pivot piece 42 of support arm 2 in the embodiment).

[0059] Further, the baby care device has a using state and a folding state. In the using state, the support arms 2 are unfolded relative to the bottom support mechanism 1, the seat surrounding rods 3 are unfolded relative to the support arms 2, the second locking mechanism 5 locks the support arms 2 and the bottom support mechanism 1 to form a fixed connection, the rotation of the seat surrounding rods 3 is limited when the support arms 2 are locked with the bottom support mechanism 1, or the two seat surrounding rods 3 are locked to form a fixed connection through the connecting structure 4 so as to limit the rotation of the seat surrounding rods 3; in the folding state, the second locking mechanism 5 unlocks the support arms 2 and the bottom support mechanism 1, and the support arms 2 are folded upward relative to the bottom support mechanism 1, and the seat surrounding rods 3 are folded downward relative to the support arms 2.

[0060] When the baby care device is used, the two support arms 2 provide support force for the two seat surrounding rods 3 in the front-rear direction of the seats, and the load acting on the two seat surrounding rods 3 is transmitted to the two support arms 2 in the front-rear direction, thereby forming front-rear support. Compared with the cantilever support and left-right support in the prior art, the support stability of the present application is better, the strength requirement of the connection between the support arms 2 and the seat surrounding rods 3 is lower, the structure is simple, and the cost is low. When folding and storing or carrying out, the two support arms 2 are folded upward, and the two seat surrounding rods 3 are folded downward, that is, the two support arms 2 and the two seat surrounding rods 3 can be folded inward and attached. Compared with the intermediate support structure in the prior art (when it is folded downward, if it is accidentally unlocked, the baby will fall out, and the safety is poor, so the intermediate support structure is folded upward), the space occupied after folding can be greatly reduced. Moreover, even if the device is accidentally unlocked during use, due to the action of the limiting structure 8, the support arms 2 can only be folded upward, and the baby will not accidentally fall out, and the safety is high.

[0061] Referring to Figure 1 , Figure 2 and Figure 4The two seat surrounding rods 3 of the embodiment are connected in a rotating manner. Preferably, the connecting structure 4 comprises a first locking mechanism 41 and an intermediate pivot piece 42. The two ends of the intermediate pivot piece 42 are pivotally connected to the one end of different seat surrounding rods 3 respectively. The first locking mechanism 41 is arranged between the two seat surrounding rods 3. The first locking mechanism 41 is used to lock the two seat surrounding rods 3 to form a fixed connection or to be unlocked. In the use state, the first locking mechanism 41 locks the two seat surrounding rods 3 to form a fixed connection. In the folding state, the first locking mechanism 41 unlocks the two seat surrounding rods 3, so that the intermediate pivot piece 42 rotates relative to the two seat surrounding rods 3. The seat surrounding rods 3 rotate downward relative to the support arm 2 to be folded. In this way, two pivot points are formed by the intermediate pivot piece 42. When the two seat surrounding rods 3 rotate downward relative to the support arm 2 to be folded, the folding angle is large, the operation is easy, the fit is good, and the hand is not easy to be pinched. In the use state, the connection part of the two seat surrounding rods 3 does not protrude upward, and the flatness is good.

[0062] Referring to Figure 4 In order to facilitate packaging and transportation, in the embodiment, the seat surrounding rod 3 comprises two sub-surrounding rods 31 arranged along the left-right direction of the seat. One end of the sub-surrounding rod 31 is pivotally connected to the intermediate pivot piece 42. The other end of the sub-surrounding rod 31 is pivotally connected to the other end of the support arm 2. Specifically, the one end of the two sub-surrounding rods 31 is pivotally connected to the two ends of the intermediate pivot piece 42 through a second pivot shaft 32 respectively. The other end of the sub-surrounding rod 31 is pivotally connected to the other end of the support arm 2 through a third pivot shaft 33. That is, the whole comprises four sub-surrounding rods 31. The sub-surrounding rod 31 is substantially L-shaped or has a certain curvature. After the four sub-surrounding rods 31 are connected to each other through the intermediate pivot piece 42 and connected to the upper parts of the two support arms 2, a seat frame substantially in the shape of a rectangle or an ellipse is formed. After a bag is installed on the seat frame, a seat for a baby or a child to sit or lie is formed.

[0063] It can be understood that, based on production needs and further facilitating packaging and transportation, the sub-surrounding rod 31 can also be made of multiple components, which will not be described here.

[0064] It can also be understood that, without considering packaging and transportation too much, the seat surrounding rod 3 can also be made as a whole that is not convenient to disassemble or cannot be disassembled.

[0065] In combination Figure 4 and Figure 5 Based on the rotating connection between the two seat surrounding rods 3 described above, as a preferred example of the first locking mechanism 41, the first locking mechanism 41 comprises a first connecting piece 411, a second connecting piece 413, a first locking block 414, a first elastic reset piece 415, a second elastic reset piece 416, and a first blocking block 417.

[0066] The first connecting piece 411 and the second connecting piece 413 are respectively fixed to different seat surrounding rods 3, the first connecting piece 411 is provided with a first lock hole 412, and the second connecting piece 413 is movably provided with a first lock block 414. When the two seat surrounding rods 3 are rotated and unfolded, the first lock block 414 is inserted into the first lock hole 412, so that the two seat surrounding rods 3 are locked to form a fixed connection. Thus, when unlocking is needed, the first lock block 414 is pulled to make it disengage from the first lock hole 412, so that the two seat surrounding rods 3 can be relatively rotated and folded. Specifically, the first lock block 414 is slidingly arranged on the second connecting piece 413, and the two ends of the first elastic return piece 415 are respectively connected to the first lock block 414 and the second connecting piece 413. The first elastic return piece 415 is preferably a spring. The first elastic return piece 415 mainly provides an elastic force acting on the first lock block 414, so that the first lock block 414 remains inserted into the first lock hole 412. A certain force is needed to overcome the elastic force of the first elastic return piece 415 to unlock, so as to avoid the stress acting on the first lock block 414 from making it slide out of the first lock hole 412 due to vibration or accidental contact.

[0067] In addition, during the switching from the folded state to the use state, in order to facilitate the locking of the first locking mechanism 41, the first lock block 414 can be provided with a first guide inclined surface. When the two seat surrounding rods 3 are relatively unfolded, the first connecting piece 411 can press the first lock block 414 through the first guide inclined surface to compress the first elastic return piece 415, until the first lock block 414 is in position with the first lock hole 412. Under the action of the elastic force of the first elastic return piece 415, the first lock block 414 is inserted into the first lock hole 412. Thus, it is not necessary to manually pull the first lock block 414 to compress the first elastic return piece 415, and the operation is convenient.

[0068] The first block 417 is movably arranged on the second connecting piece 413, and the two ends of the second elastic return piece 416 are respectively connected to the first block 417 and the second connecting piece 413. The first block 417 is used to lock or unlock the first lock block 414. Specifically, the sliding direction of the first block 417 intersects with the sliding direction of the first lock block 414. The second elastic return piece 416 is preferably a spring. The second elastic return piece 416 mainly provides an elastic force acting on the first block 417, so that the first block 417 remains in a pop-up state. When the first lock block 414 is inserted into the first lock hole 412, the first block 417 is popped up under the action of the second elastic return piece 416 to lock the first lock block 414, so as to limit the first lock block 414 from disengaging from the first lock hole 412. When the first block 417 is pressed to unlock the first lock block 414, the first lock block 414 is allowed to be pulled to disengage from the first lock hole 412. Thus, the double-locking structure is adopted to prevent misoperation and improve safety.

[0069] Referring toFigure 1 and Figure 4 In the present embodiment, preferably, in the use state, the first connecting piece 411 and the second connecting piece 413 are both located below the middle pivot piece 42, and one end surface of the first connecting piece 411 and one end surface of the second connecting piece 413 abut against each other, so that the seat surrounding rod 3 can be prevented from rotating upwardly loose in the use state, and the seat surrounding rod 3 can also be prevented from being upwardly folded by mistake to cause the space occupation when folding is needed; further, the abutment position of the first connecting piece 411 and the second connecting piece 413 is located between the pivot points at the two ends of the middle pivot piece 42, so that the longest span of each connecting piece can be reduced, the strength of the connecting piece is better, the stability of the locking is higher, and under the abutment effect of the two connecting pieces, the seat surrounding rod 3 will not have a loose feeling, and the baby sitting or lying thereon will not be frightened.

[0070] In addition, the rotation connection mode adopted in the present embodiment has the advantages that after the cloth pocket is installed, the unlocking and locking operations can be conveniently realized without affecting or with less affecting the wrapping rate of the cloth pocket on the seat surrounding rod 3.

[0071] Referring to Figures 6 to 8 In the present embodiment, the bottom support mechanism 1 comprises a first mounting seat 11, and the first mounting seat 11 is provided with a connecting arm 12, and the connecting arm 12 is used for being pivotally connected with one end of the support arm 2. Specifically, the two ends of the connecting arm 12 are respectively pivotally connected with one end of one support arm 2 through a first pivot shaft 21.

[0072] Preferably, the relative position of the connecting arm 12 on the first mounting seat 11 is adjustable, so as to move the connecting arm 12 together with the support arm 2 and the seat surrounding rod 3 relative to the first mounting seat 11 by adjusting the connecting arm 12, so as to change the reclining angle of the seat. The first mounting seat 11 is provided with an arc-shaped sliding groove 111, and the connecting arm 12 is slidingly arranged in the arc-shaped sliding groove 111. The first mounting seat 11 is further provided with a third locking mechanism 6, and the third locking mechanism 6 is used for locking the connecting arm 12 at a preset position to limit the sliding of the connecting arm 12 relative to the first mounting seat 11, or unlocking the connecting arm 12 to allow the sliding of the connecting arm 12 relative to the first mounting seat 11.

[0073] Specifically, the first mounting seat 11 comprises a seat body 112 and an upper cover 113, and the upper cover 113 is detachably connected with the seat body 112 by screws or the like. The arc-shaped sliding groove 111 is formed between the seat body 112 and the upper cover 113, and the arc-shaped sliding groove 111 is mainly arranged on the seat body 112. In assembly, the connecting arm 12 is embedded on the seat body 112, and then the upper cover 113 is installed, so that the connecting arm 12 is clamped between the seat body 112 and the upper cover 113 and can slide on the arc-shaped sliding groove 111.

[0074] As a preferred example of the third locking mechanism 6, the third locking mechanism 6 comprises a knob 61, a screwing block 62 and a pressing block 63, the screwing block 62 is arranged on the first mounting base 11, the pressing block 63 is slidingly arranged on the first mounting base 11, the knob 61 is threadedly connected with the screwing block 62, the knob 61 and the pressing block 63 are abuttingly matched, the axial direction of the knob 61 and the sliding direction of the pressing block 63 are intersected; specifically, the seat body 112 is provided with an upwardly open mounting groove, the mounting groove is communicated with the arc-shaped sliding groove 111, the screwing block 62 is inserted into the mounting groove from top to bottom, the screwing block 62 is limited to be immovable by the abutting pressure of the upper cover 113, the pressing block 63 is slidingly arranged in the mounting groove, the pressing block 63 is located on one side of the screwing block 62, the side surface of the seat body 112 is further provided with an avoiding hole communicated with the mounting groove, one end of the knob 61 is penetrated out of the avoiding hole, the other end of the knob 61 is formed in a taper shape, the axial line of the knob 61 is horizontally arranged, that is to say, the moving direction of the knob 61 and the moving direction of the pressing block 63 are intersected, the lower side of the pressing block 63 is provided with a slope matched with the other end of the knob 61, when the knob 61 is twisted, the knob 61 drives the pressing block 63 to move towards the connecting arm 12 to form a pressing locking. In the third locking mechanism 6, the transverse movement of the knob 61 is converted into the up-and-down movement of the pressing block 63, the operation is simple and convenient, and loosening is not easy to occur.

[0075] It can be understood that the screwing block 62 can also be directly fixed on the first mounting base 11; or the screwing block 62 is integrally formed on the first mounting base 11, the screwing block 62 is a part of the first mounting base 11 to realize the cooperation with the knob 61, that is to say, it can be understood that an internal thread matched with the knob 61 is arranged on the first mounting base 11, the part with the internal thread is the screwing block 62, when the knob 61 is twisted, the knob 61 is moved to drive the pressing block 63.

[0076] Referring to Figures 6 to 8As a preferred example of the second locking mechanism 5, the second locking mechanism 5 comprises a first sliding sleeve 51, a third elastic reset member 52, and a second blocking block 53. The first sliding sleeve 51 is slidingly arranged on the support arm 2. When the support arm 2 is unfolded, the first sliding sleeve 51 slides towards the connecting arm 12 and is sleeved to the connecting arm 12, thereby locking the support arm 2 and the bottom support mechanism 1 to form a fixed connection. When it is necessary to unlock, the first sliding sleeve 51 is actuated to be separated from the connecting arm 12, thereby allowing the support arm 2 to rotate and fold. The second blocking block 53 is arranged on the support arm 2 and is used to lock or unlock the first sliding sleeve 51 to prevent accidental unlocking of the first sliding sleeve 51. The two ends of the third elastic reset member 52 are connected to the support arm 2 and the second blocking block 53, respectively. The third elastic reset member 52 is preferably a spring. The third elastic reset member 52 mainly provides an elastic force acting on the second blocking block 53, so that the second blocking block 53 is kept in a pop-up state. When the first sliding sleeve 51 is sleeved to the connecting arm 12, the second blocking block 53 is popped up under the action of the third elastic reset member 52 to lock the first sliding sleeve 51, thereby limiting the first sliding sleeve 51 from being separated from the connecting arm 12. When the second blocking block 53 is pressed to unlock the first sliding sleeve 51, the first sliding sleeve 51 is allowed to be actuated to be separated from the connecting arm 12.

[0077] In the above-mentioned scheme of the second locking mechanism 5, the first sliding sleeve 51 is used to realize the locking and unlocking between the support arm 2 and the connecting arm 12. Since the cross section of the first sliding sleeve 51 is large, compared with other locking modes, the first sliding sleeve 51 can provide strong shear stress, so that good support strength can be provided in the use state, and the overall structure is simple and the production cost is low. By arranging the second blocking block 53, the situation of accidental unlocking of the first sliding sleeve 51 can be avoided.

[0078] In addition, in order to facilitate the first sliding sleeve 51 to switch from the unlocked state to the locked state, a second guide inclined surface is arranged on the side of the second blocking block 53 away from the connecting arm 12. In this way, when the first sliding sleeve 51 slides towards the connecting arm 12, the first sliding sleeve 51 can press the second locking block 72 through the second guide inclined surface to compress the third elastic reset member 52, so that it is not necessary to manually press the second blocking block 53 to compress the third elastic reset member 52, and the operation is convenient.

[0079] In addition, in order to avoid the first sliding sleeve 51 from sliding everywhere in the folded state to cause abnormal sound, or to avoid the first sliding sleeve 51 from loosening and resetting towards the connecting arm 12 when it is unlocked but not folded, a positioning hole 511 cooperating with the second locking block 72 is further arranged on the first sliding sleeve 51. When the first sliding sleeve 51 is in the unlocked state, the second blocking block 53 is embedded in the positioning hole 511, thereby positioning the first sliding sleeve 51 in the unlocked state.

[0080] In another preferred embodiment, the second locking mechanism 5 can also adopt a way of a latch or a bolt to form locking or unlocking to the support arm 2. For example, a latch is arranged on one of the support arm 2 and the connecting arm 12, and a corresponding latch hole is arranged on the other one of the support arm 2 and the connecting arm 12; or a corresponding latch hole is arranged on each of the support arm 2 and the connecting arm 12, and a bolt is used to pass through the two latch holes to form locking.

[0081] Referring to Figure 8 In the embodiment, the limiting structure 8 includes a limiting block 81 and a limiting slot 82 which are in abutting cooperation, wherein the limiting block 81 is arranged on the support arm 2, and the limiting slot 82 is arranged on the connecting arm 12. When the support arm 2 is rotated downward to the use state, the limiting block 81 is embedded in the limiting slot 82 and forms abutting, so as to limit the support arm 2 from continuing to rotate downward, and thus the support arm 2 can only be folded upward but not downward when switching from the use state to the folding state. Based on that the limiting block 81 is arranged on the support arm 2 and the limiting slot 82 is arranged on the connecting arm 12, the limiting block 81 and the limiting slot 82 are located below.

[0082] Of course, the arrangement objects of the limiting block 81 and the limiting slot 82 can also be interchanged, for example, the limiting block 81 is arranged on the connecting arm 12, and the limiting slot 82 is arranged on the support arm 2. At this time, the limiting block 81 and the limiting slot 82 are located above.

[0083] By using the cooperation of the limiting block 81 and the limiting slot 82, the flatness of the connecting arm 12 and the support arm 2 at the connection position can be conveniently controlled, so as to facilitate the sliding of the first sliding sleeve 51.

[0084] In other preferred embodiments, other known limiting structures 8 can also be used, for example, the end faces of the support arm 2 and the connecting arm 12 are abutted to provide limiting, so as to meet the function of limiting the support arm 2 from rotating downward to fold, and thus no further elaboration is made herein.

[0085] It can be understood that, based on the production needs and further facilitating packaging and transportation, the support arm 2 and the connecting arm 12 can be made of multiple components, and thus no further elaboration is made herein, and the specific component structure of the support arm 2 and the connecting arm 12 is not limited in the utility model.

[0086] In summary, the above-mentioned folding scheme mainly solves the folding problem of the seat structure, and has less relevance with the bottom support mechanism 1, and thus the application scenarios are limited.

[0087] In order to further reduce the space occupied by the infant care equipment when being folded and stored, the embodiment also provides a foldable scheme of the support leg 14 in the bottom support mechanism 1.

[0088] Referring to Figure 3 , Figures 9 to 13As a preferred example of the bottom supporting mechanism 1, the bottom supporting mechanism 1 comprises a first mounting base 11, a second mounting base 13, a driving device 16, a plurality of supporting legs 14, a shell 15, the supporting legs 14 are connected with the second mounting base 13, the driving device 16 is mounted on the second mounting base 13, the first mounting base 11 is connected with the driving device 16, the supporting legs 14 support the second mounting base 13, the second mounting base 13 supports the driving device 16, the driving device 16 supports the first mounting base 11, the shell 15 is connected with the second mounting base 13 and wraps the second mounting base 13, and the shell 15 also wraps most parts of the driving device 16. The supporting legs 14 are pivoted to the second mounting base 13, the rotation axis between the supporting legs 14 and the second mounting base 13 extends along the left-right direction of the seat, and the supporting legs 14 can be folded upward relative to the second mounting base 13; the fourth locking mechanism 7 is further arranged on the second mounting base 13, and is used for locking the supporting legs 14 in the folded position or the unfolded supporting position.

[0089] In the above scheme, the folding direction of the supporting legs 14 corresponds to the folding direction of the supporting arms 2, and both are folded upward to the middle, so that the overall folded volume is small, and the overall storage and carrying during travel can be facilitated.

[0090] Specifically, the supporting legs 14 are provided in two, the two supporting legs 14 are arranged along the front-rear direction of the seat, the supporting legs 14 are substantially in U shape, each of the supporting legs 14 is provided with a gear tooth 141, and the gear teeth on the two supporting legs 14 are engaged with each other, so that the two supporting legs 14 are synchronously rotated when being folded or unfolded, thereby facilitating the operation.

[0091] It can be understood that, based on the production needs and further facilitating the packaging and transportation, the supporting legs 14 can be made of a plurality of components, which will not be described here, and the specific component structure of the supporting legs 14 is not limited in the utility model.

[0092] Referring to Figure 12 and Figure 13As a preferred example of the fourth locking mechanism 7, the fourth locking mechanism 7 comprises a first sliding block 71, a second locking block 72, a third blocking block 73, a fourth elastic reset member 74, and a fifth elastic reset member 75. The first sliding block 71 is slidingly arranged in the second mounting seat 13 along a first direction. The second locking block 72 is slidingly arranged in the second mounting seat 13 along a second direction. The first sliding block 71 is connected with the second locking block 72. The first direction intersects with the second direction. The gear is provided with a first pin hole 142. The second locking block 72 is provided with a pin column 721. When the first sliding block 71 is actuated, the first sliding block 71 drives the second locking block 72 to slide, so that the pin column 721 is inserted into the first pin hole 142 to form a lock, thereby making the supporting leg 14 unable to rotate. The fifth elastic reset member 75 is connected with the second locking block 72 and the second mounting seat 13 at both ends, respectively. The fifth elastic reset member 75 is preferably a spring. The fifth elastic reset member 75 provides an elastic force acting on the second locking block 72, so that the pin column 721 on the second locking block 72 is kept inserted into the first pin hole 142 to form a lock, and the first sliding block 71 is kept in a reset state.

[0093] Preferably, the first pin hole 142 is provided with at least two first pin holes 142 corresponding to the folded position and the unfolded supporting position of the supporting leg 14. Of course, the first pin hole 142 can also be provided with a larger number, such as three, four, etc., to correspond to the locking of the supporting leg 14 at other required positions.

[0094] Among them, in order to realize that the first sliding block 71 can drive the second locking block 72 to slide, as a specific example, the first sliding block 71 is provided with an inclined slot 711, and the second locking block 72 is provided with a driving block 722. The driving block 722 is slidingly arranged in the inclined slot 711. When the first sliding block 71 slides along the first direction, the driving block 722 is driven to slide relative to the inclined slot 711, and the driving block 722 drives the second locking block 72 to slide along the second direction.

[0095] Of course, the setting objects of the inclined slot 711 and the driving block 722 can also be interchanged, such as the inclined slot 711 being arranged on the second locking block 72, and the driving block 722 being arranged on the first sliding block 71.

[0096] In other preferred embodiments, other known connection modes of the first sliding block 71 and the second locking block 72 can also be used to meet the function of limiting the driving of the first sliding block 71 to the second locking block 72, which will not be described here.

[0097] The third block 73 is used for locking or unlocking the first slider 71 to prevent misoperation. Specifically, the housing 15 is provided with a first through slot 151, and a portion of the first slider 71 extends out of the first through slot 151. The third block 73 is movably arranged on the first slider 71, and the fourth elastic reset member 74 has two ends respectively connected to the first slider 71 and the third block 73. The fourth elastic reset member 74 is preferably a spring, and mainly provides an elastic force acting on the third block 73. When the pin column 721 is inserted into the first pin hole 142, the third block 73 is popped out and located outside the first through slot 151 under the action of the fourth elastic reset member 74, and the third block 73 can abut against the housing 15 to prevent the first slider 71 from being moved, so that the pin column 721 remains inserted into the first pin hole 142.

[0098] It should be noted that the driving device 16 can be any structure for driving the seat to move, which is irrelevant to the utility model concept of the present application, and therefore, the specific scheme of the driving device 16 is not limited. In order to facilitate understanding and as an implementable example, the driving device 16 includes a motor, a swing arm, a limiting sliding groove, a limiting member, a first rotating shaft, and a second rotating shaft. The first rotating shaft is pivotally connected to the second mounting seat 13. One end of the swing arm is fixedly connected to the first rotating shaft. The second rotating shaft is pivotally connected to the other end of the swing arm. One end of the second rotating shaft is fixedly connected to the limiting member. One end of the second rotating shaft is fixedly connected to the first mounting seat 11. The limiting sliding groove is arranged on the second mounting seat 13. The limiting member cooperates with the limiting sliding groove. The motor is installed on the second mounting seat 13 and is in transmission connection with the first rotating shaft, or the motor can be in transmission connection with the swing arm.

[0099] Embodiment 2

[0100] Referring to Figure 14 and Figure 15 , the embodiment also discloses a foldable and storable baby care device. The difference between the embodiment and the embodiment 1 is that the two seat surrounding rods 3 are detachable.

[0101] In the embodiment, the opposite ends of the two seat surrounding rods 3 are relatively detachable. The connecting structure 4 includes a first locking mechanism 41 arranged between the two seat surrounding rods 3. In the use state, the first locking mechanism 41 locks the two seat surrounding rods 3 to form a fixed connection. In the folding state, the first locking mechanism 41 unlocks the two seat surrounding rods 3, so that the opposite ends of the two seat surrounding rods 3 are disconnected, and the seat surrounding rods 3 rotate downward to be folded relative to the supporting arms 2.

[0102] Thus, when it is needed to use, after the support arm 2 is rotated to be unfolded and locked, the seat surrounding rods 3 are rotated to be unfolded upward relative to the support arm 2, the opposite ends of the two seat surrounding rods 3 are close to or adhere to or are embedded, and then the opposite ends of the two seat surrounding rods 3 are locked by the first locking mechanism 41 to be fixedly connected, so as to limit the rotation of the two seat surrounding rods 3, thereby enabling normal use; when it is needed to fold, the first locking mechanism 41 is unlocked to make the two seat surrounding rods 3 rotatable, so as to rotate the seat surrounding rods 3 downward to be folded.

[0103] Referring to Figure 16 In the embodiment, based on the aforementioned detachable structure between the two seat surrounding rods 3, as a preferred example of the first locking mechanism 41, the first locking mechanism 41 comprises a second sliding sleeve 43, a fourth stop block 418 and a sixth elastic reset member 419. The second sliding sleeve 43 is slidably arranged on one of the seat surrounding rods 3. When the seat surrounding rod 3 is rotated to be unfolded relative to the support arm 2, the second sliding sleeve 43 slides towards the other seat surrounding rod 3 and is sleeved to the other seat surrounding rod 3, so as to lock the two seat surrounding rods 3 to be fixedly connected. Thus, when the support arm 2 is locked and the seat surrounding rods 3 are locked, the freedom degree of the linkage structure formed thereby is zero, thereby providing stable support.

[0104] The fourth stop block 418 is slidably arranged on the seat surrounding rod 3 on which the second sliding sleeve 43 is arranged, and the sixth elastic reset member 419 is connected to the seat surrounding rod 3 and the fourth stop block 418 at two ends thereof. The fourth stop block 418 is used to lock or unlock the second sliding sleeve 43, so as to prevent misoperation. The sixth elastic reset member 419 is preferably a spring. The sixth elastic reset member 419 mainly provides elastic force acting on the fourth stop block 418, so that the fourth stop block 418 is kept in a pop-up state. When the second sliding sleeve 43 is sleeved to the other seat surrounding rod 3, the fourth stop block 418 is popped up under the action of the sixth elastic reset member 419 to lock the second sliding sleeve 43, so as to limit the second sliding sleeve 43 from being separated from the other seat surrounding rod 3. When the fourth stop block 418 is pressed to unlock the second sliding sleeve 43, the second sliding sleeve 43 is allowed to be actuated to be separated from the other seat surrounding rod 3.

[0105] In order to avoid the second sliding sleeve 43 from being separated from the seat surrounding rod 3 during the sliding process towards the other seat surrounding rod 3, a ring-shaped flange can be arranged at the end of the seat surrounding rod 3, which can be matched with the second sliding sleeve 43 to avoid the second sliding sleeve 43 from being separated.

[0106] In addition, the seat surrounding rod 3 on which the second sliding sleeve 43 is arranged can further be provided with a sixth stop block for limiting the sliding range of the second sliding sleeve 43 backward, so as to control the stroke of the second sliding sleeve 43 when the second sliding sleeve 43 is unlocked to the two seat surrounding rods 3.

[0107] It should be noted that other identical technical features can refer to the relevant description of Embodiment 1, which will not be repeated here.

[0108] Embodiment 3

[0109] Referring to Figures 16 to 18 , this embodiment also discloses a foldable baby care device. The difference between this embodiment and Embodiments 1 or 2 is that a single pivot point is used to achieve the rotating connection between the two seat surrounding rods 3.

[0110] In this embodiment, the two seat surrounding rods 3 rotate around a single pivot point. The connecting structure 4 includes a fourth pivot shaft 44 connected to the opposite ends of the two seat surrounding rods 3, so that the two seat surrounding rods 3 rotate relative to each other around the fourth pivot shaft 44.

[0111] In this way, when the two support arms 2 are locked and cannot rotate, since a single pivot point is formed between the two seat surrounding rods 3, the degree of freedom of the connecting rod structure formed by the support arms 2 is zero when the support arms 2 are locked, so that the two seat surrounding rods 3 cannot rotate relative to each other. That is, when the support arms 2 are locked with the bottom support mechanism 1, the rotation of the seat surrounding rods 3 is limited, thereby providing stable support. In order to meet the folding angle requirements, the structure of the end of the seat surrounding rods 3 can be changed accordingly, so that the position of the fourth pivot shaft 44 is moved upward.

[0112] Based on the use of a single pivot point between the two seat surrounding rods 3, the entire device cannot rotate when the support arms 2 are locked. At this time, the first locking mechanism 41 can not be provided.

[0113] When the load acts on the two seat surrounding rods 3, the two seat surrounding rods 3 will generate an inward pulling force on the two support arms 2, causing the support arms 2 to elastically deform or bend, resulting in an unstable and loose feeling. Therefore, in this embodiment, the first locking mechanism 41 is preferably provided between the two seat surrounding rods 3. In the use state, the first locking mechanism 41 locks the two seat surrounding rods 3 to form a fixed connection. In the folded state, the first locking mechanism 41 unlocks the two seat surrounding rods 3, so that the two seat surrounding rods 3 rotate relative to each other around the fourth pivot shaft 44, and the seat surrounding rods 3 rotate downward relative to the support arms 2 to fold. At this time, one function of the first locking mechanism 41 is to share the load, thereby improving the stability in the use state, so that the seat surrounding rods 3 do not have a loose feeling, and the baby sitting or lying on them does not feel scared.

[0114] Specifically, referring to Figure 17 and Figure 18, based on the single pivot joint scheme described above, in this embodiment, as a preferred example scheme of the first locking mechanism 41, the first locking mechanism 41 includes a third locking block 4110, a seventh elastic reset member 4111, an eighth elastic reset member 4112, and a fifth stop block 4113. The third locking block 4110 and the fifth stop block 4113 are both slidably arranged at one end of one of the seat surrounding rods 3. The sliding direction of the third locking block 4110 intersects the sliding direction of the fifth stop block 4113. The two ends of the seventh elastic reset member 4111 are respectively connected to the seat surrounding rod 3 and the third locking block 4110. The two ends of the eighth elastic reset member 4112 are respectively connected to the seat surrounding rod 3 and the fifth stop block 4113. The fifth stop block 4113 is used to lock or unlock the third locking block 4110. The other end of the seat surrounding rod 3 is provided with a second lock hole 34 for plug-in cooperation with the third locking block 4110. When the two seat surrounding rods 3 are rotated and unfolded, the third locking block 4110 is inserted into the second lock hole 34 under the action of the seventh elastic reset member 4111, thereby locking the two seat surrounding rods 3 to form a fixed connection. The fifth stop block 4113 is popped out under the action of the eighth elastic reset member 4112 to lock the third locking block 4110, thereby limiting the third locking block 4110 from disengaging from the second lock hole 34. When the third locking block 4110 is unlocked by pressing the fifth stop block 4113, the third locking block 4110 is allowed to be moved to disengage from the second lock hole 34.

[0115] Referring to Figure 17 and Figure 18 , in order to facilitate the installation and locking cooperation of the first locking mechanism 41 on the seat surrounding rod 3, a joint member structure is adopted between the two seat surrounding rods 3. One of the seat surrounding rods 3 includes a first joint member 311, the other seat surrounding rod 3 includes a second joint member 312 and an auxiliary block 313, and the fourth pivot shaft 44 is arranged at one end of the first joint member 311 and the second joint member 312. Specifically, with the direction shown in Figure 17 as a reference, the other end of the first joint member 311 is inserted into one end of the left sub-surrounding rod 31, the other end of the second joint member 312 is inserted into one end of the right sub-surrounding rod 31, and the auxiliary block 313 is connected to the other end of the second joint member 312 away from the fourth pivot shaft 44. When the second joint member 312 is inserted into the right sub-surrounding rod 31, the auxiliary block 313 is also located inside the right sub-surrounding rod 31. The third locking block 4110, the seventh elastic reset member 4111, the eighth elastic reset member 4112, and the fifth stop block 4113 are installed on the second joint member 312 and the auxiliary block 313. The second lock hole 34 is arranged on the first joint member 311. In this way, the first locking mechanism 41 can be pre-installed on the second joint member 312 and then installed together in the corresponding sub-surrounding rod 31, thereby facilitating production and packaging and transportation.

[0116] It should be noted that other identical technical features can refer to the related description of Embodiment 1, which will not be repeated here.

[0117] The technical means disclosed in the utility model scheme are not limited to the technical means disclosed in the above-mentioned embodiments, and also include technical schemes composed of any combination of the above technical features. It should be pointed out that, for ordinary skilled persons in the art, without departing from the principles of the utility model, a number of improvements and refinements can be made, and these improvements and refinements are also considered to be within the protection scope of the utility model.
