DETAILED DESCRIPTION OF THE INVENTION

[0023] In order to make the objectives, technical solutions and advantages of the present disclosure clearer, the present disclosure will be described in more detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present disclosure and do not limit the protection scope of the present disclosure.

[0024] When an element is defined as "fixed to" another element, it should be understood that the element is either directly on the other element or indirectly on the other element through an intervening element. When an element is considered to be "connected" to another element, the element may be directly connected to the other element or indirectly connected to the other element through an intervening element. Terms such as "vertical," "horizontal," "left," and "right" used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0025] 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 disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed objects.

[0026] 1 and 2, an embodiment of the present disclosure provides a child carrier, such as a child safety seat. The child safety seat includes a protector 10, a seat 20, and a connection adjustment mechanism 30 disposed between the protector 10 and the seat 20. The connection adjustment mechanism 30 can realize a detachable connection between the protector 10 and the seat 20 and an arrangement of a seating space between the protector 10 and the seat 20. The connection adjustment mechanism 30 has a simple structure and is easy to operate.

[0027] Specifically, as shown in FIGS. 3 to 5, the protector 10 may have a lightweight solid block structure or housing structure made of a foam material such as expanded polystyrene (EPS), expanded polypropylene (EPP), or expanded polyethylene polystyrene (EPO). In this embodiment, the protector 10 has a first surface 11 facing the seat 20. The first surface 11 is concave and surrounds and forms a seating space for accommodating a child in the seat 20. The protector 10 also has a second surface 12 facing away from the seat 20. The second surface 12 is convex and partially approximately spherical. As shown in FIG. 5, vertical reinforcements 13 and horizontal reinforcements 14 are arranged in a cross shape on the second surface 12 to increase the compressive strength of the protector 10. The protector 10 may be covered with a layer of flexible cover, such as a fabric cover 15 (shown in FIG. 4), to prevent the user from being scratched by the longitudinal reinforcements 13 and transverse reinforcements 14 on the surface of the protector 10. This also makes the protector 10 more pleasing to the eye.

[0028] Specifically, as shown in FIGS. 6 to 8, the seat 20 includes a base 21 and a backrest 22 connected to each other. The base 21 includes a base support 21a and a connecting rod 21b. The connecting rod 21b is inclined relative to the base support 21a, and one end of the connecting rod 21b is fixed to the base support 21a by welding, and the other end of the connecting rod 21b is provided with a first connecting portion 21c and a first abutment surface 21d. In this embodiment, the base support 21a, the connecting rod 21b, and the backrest 22 are all covered with a layer of seat cover to improve the riding comfort of children. The seat cover may be made of a plastic material. Optionally, the seat cover may cover the other end of the connecting rod 21b and form the first abutment surface 21d.

[0029] Specifically, as shown in FIGS. 9 and 10, the connection adjustment mechanism 30 includes a slide tube 100, a slide assembly, an operating member 300, and a slide housing 400.

[0030] Optionally, as shown in Figures 4, 9, and 10, the slide tube 100 is provided with a plurality of positioning portions 110 along its extending direction, and one end of the slide tube 100 is fixedly connected to the protector 10. In this embodiment, the lateral stiffener 14 has a U-shaped tubular structure and is arranged along the lateral direction of the protector 10. One end of the slide tube 100 is fixedly connected to the end of the lateral stiffener 14.

[0031] 10 to 14, the slide assembly includes a slide member 210, a connecting member 220, an adjusting member 230, and an elastic member 240. The slide member 210 is slidably disposed on the slide tube 100, and the connecting member 220 is movably disposed on the slide member 210. The operating member 300 is movably disposed on the slide member 210. When the operating member 300 slides or rotates in a first direction D1, the connecting member 220 can slide or rotate relative to the slide member 210. When the operating member 300 slides or rotates in a second direction D2, the slide member 210 can slide relative to the slide tube 100. The first direction D1 is opposite to the second direction D2. In this embodiment, the operating member 300 is slidably disposed on the operating member 210. The first direction D1 corresponds to the right direction in FIG. 14, and the second direction D2 corresponds to the left direction in FIG. 14. In another embodiment, the operating member 300 may be pivotally connected to the slide member 210 .

[0032] 11 , the slide member 210 includes a sleeve portion 211, a slide sheet portion 212, and a bushing 213. The sleeve portion 211 and the slide sheet portion 212 are connected to each other, and the sleeve portion 211 is disposed outside the slide tube 100. The slide sheet portion 212 is substantially elongated, and is provided with a first through hole 212a, a second through hole 212b, a third through hole 212c, and a fourth through hole 212d in this order along its longitudinal direction. Two bushings 213 are provided, both of which are disposed outside the slide tube 100 and fixedly connected to both sides of the sleeve portion 211.

[0033] 10, 14, and 15, both the connecting member 220 and the adjusting member 230 are pivotally connected to the sliding seat portion 212 and are spaced apart from each other. Two ends of the operating member 300 abut against the connecting member 220 and the adjusting member 230, respectively. The connecting member 220 is provided with a second connecting portion (shown in FIG. 12) that is detachably coupled to the first connecting portion 21c of the connecting rod 21d. The adjusting member 230 is provided with an adjusting portion 231 (shown in FIG. 13) that is detachably connected to the positioning portion 110. When the operating member 300 slides in the first direction D1, the connecting member 220 rotates in the third direction relative to the sliding member 210. When the operating member 300 rotates in the second direction D2, the adjusting member 230 rotates in the third direction D4 relative to the sliding member 210. The third direction D3 and the fourth direction D4 are, for example, counterclockwise and clockwise, respectively. The middle portion of the elastic member 240 is fixed to the main dry cell member 210, and its two ends abut against the connecting member 220 and the adjusting member 230, respectively. The elastic member 240 constantly urges the connecting member 220 to rotate in the fourth direction D4. The elastic member 240 constantly urges the adjusting member 230 to rotate in the third direction D3.

[0034] In this embodiment, as shown in FIGS. 10, 14, and 15, the elastic member 240 includes a double torsion spring, and two spring coils 241 of the double torsion spring are fixed to the slide seat portion 212. In this embodiment, the slide assembly further includes a first fixing pin (not shown) and a second fixing pin (not shown). The first fixing pin is inserted into and fixed in the second through hole 212b (shown in FIG. 11), and the second fixing pin is inserted into and fixed in the third through hole 212c (shown in FIG. 11). Two spring coils 241 are disposed on the first fixing pin and the second fixing pin, respectively, thereby realizing the fixation of the two spring coils 241 on the slide member 210. Two ends 242 of the double torsion spring abut against the connecting member 220 and the adjusting member 230, respectively. In this way, the rotation of the connecting member 220 and the adjusting member 230 is simultaneously driven by one operating member 300, realizing the detachment between the seat 20 and the protector 10 and the adjustment of the size of the seating space between the seat 20 and the protector 10. The elastic member 240 allows the connecting member 220 or the adjusting member 230 to smoothly return to its original position after rotation, whereby the connecting member 220 is reconnected to the seat 20 and the adjusting member 230 is reconnected to the slide tube 100.

[0035] In this embodiment, as shown in Fig. 12, the connecting member 220 has a substantially irregular sheet-like structure. The connecting member 220 includes a first protrusion 223, a second protrusion 224, and a third protrusion 225. The connecting member 220 is provided with a first mounting hole 222. The first protrusion 223, the second protrusion 224, and the third protrusion 225 are arranged along the circumferential direction of the first mounting hole 222. Referring to Figs. 11 and 15, the slide assembly further includes a first rotation shaft (not shown), which passes through the first mounting hole 222 and the first through-hole 212a and realizes a pivotal connection between the connecting member 220 and the slide member 210. The first protrusion 223 abuts against the operating member 300, the second protrusion 224 abuts against the end 242 of the double torsion spring, and the third protrusion 225 is provided with a second connecting portion configured to be detachably coupled to the seat 20. Alternatively, the first protrusion 223 and the second protrusion 224 are arranged on the side of the first mounting hole 222 and proximal to the adjustment member 230. The first protrusion 223 is close to the operating member 300, and the second protrusion 224 is close to the slide tube 100. The third protrusion 225 is arranged on the side of the first mounting hole 222 and distal to the adjustment member 230.

[0036] In this embodiment, as shown in FIG. 13 , the adjustment member 230 has a generally irregular sheet-like structure. The adjustment member 230 includes a fourth protrusion 233 and a fifth protrusion 234. The adjustment member 230 is provided with a second mounting hole 232. The fourth protrusion 233 and the fifth protrusion 234 are arranged along the circumferential direction of the second mounting hole 232. Referring to FIGS. 11 and 15 , the slide assembly further includes a second rotation shaft (not shown). The second rotation shaft passes through the second mounting hole 232 and the fourth through-hole 212d and realizes a pivotal connection between the adjustment member 230 and the slide member 210. The fourth protrusion 233 abuts against the operating member 300. The fifth protrusion 234 abuts against the other end 233 of the double torsion spring. The fifth protrusion 234 has an adjustment portion 231, which is detachably connected to the positioning portion 110. Both the fourth protrusion 233 and the fifth protrusion 234 are disposed on the side of the second mounting hole 232, proximal to the connecting member 220. The fifth protrusion 233 is adjacent to the operating member 300, and the fifth protrusion 234 is adjacent to the slide tube 100. As long as the above-mentioned features of detachment between the seat 20 and the protector 10 and size adjustment of the sitting space between the seat 20 and the protector 10 can be realized, the shapes and structures of the connecting member 220 and the adjusting member 230 may be other forms, such as an irregular polygonal shape.

[0037] 14 and 15, a slide housing 400 is slidably disposed in the slide tube 100 and fixedly connected to the slide member 210. Both the slide member 210 and the adjustment member 230 are disposed within the slide housing 400. One portion of the connecting member 220 is disposed within the slide housing 400. The other portion of the connecting member 220 has a second connecting portion 221 and protrudes from an opening in the slide housing 400 to connect with the first connecting portion 21c of the connecting rod 21b. One portion of the operating member 300 is disposed outside the slide housing 400 for user operation. The other portion of the operating member 300 extends into the slide housing 400 through another opening in the slide housing 400 and is slidably connected to the slide member 210. The slide housing 400 is provided to protect various components of the slide assembly from damage and falling. The slide housing 400 also prevents users from being scratched by some sharp parts.

[0038] Optionally, as shown in Figures 4 and 6, first connecting rod 21b has a first abutment surface 21d, and slide assembly has a second abutment surface 410. When first coupling portion 21c is coupled to second coupling portion 221, first abutment surface 21d abuts against second abutment surface 410. In this embodiment, second abutment surface 410 is located on a side of the slide housing, proximal to second coupling portion 221 (shown in Figures 14 and 15).

[0039] 13 and 15 , the positioning portion 110 may include a plurality of first female connectors arranged along the extension direction of the slide tube 100, and the adjustment member 231 may include a first male connector that is detachably coupled to the positioning portion 110. Alternatively, the positioning portion 110 may include a plurality of first male connectors arranged along the extension direction of the slide tube 100, and the adjustment member 231 may include a first female connector that is detachably coupled to the positioning portion 110.

[0040] In this embodiment, as shown in FIGS. 13 and 15 , the positioning portion 110 includes multiple positioning grooves arranged along the extension direction of the slide tube 100. The adjustment member 231 includes positioning protrusions arranged on the adjustment member 230, which can be clamped in the positioning grooves. When the multiple positioning protrusions are clamped in different positioning grooves, the slide assembly is positioned at different positions on the slide tube 100. At this time, the first connecting portion 21c and the second connecting portion 221 are connected, and the slide assembly and the seat 20 are fixed relative to each other. The protector 10, together with the slide tube 100, moves to positions spaced apart from the seat 20 by different distances, thereby adjusting the seating space between the protector 10 and the seat 20. The connecting structure between the positioning grooves and the positioning protrusions is relatively simple and easy to implement. In other embodiments, the positioning portion 110 may include multiple positioning protrusions, and the adjustment portion 231 may include corresponding positioning grooves, but this is not limited to this. Alternatively, the positioning portion 110 may include a plurality of positioning rings arranged along the extension direction of the slide tube 100, and the adjustment portion 231 may include a positioning hook arranged on the connection portion 220.

[0041] Optionally, at least two positioning protrusions may be provided, and the at least two positioning protrusions may be clamped simultaneously in the at least two grooves, respectively. In this way, the coupling and connection between the adjustment member 230 and the slide tube 100 may be more stable. The number of positioning protrusions may be set to more than two or less than two according to actual circumstances.

[0042] 13 and 15, the side of the positioning protrusion that abuts against the groove wall of the positioning groove has an inclined surface 231a. Therefore, when the protector 10 moves toward or away from the seat 20, the user can directly push the protector 10 without operating the operating member 300, making operation easier. For example, the inclined surface 231c is disposed on the side of the positioning protrusion that is proximal to the protector 10. The inclined surface 231a is inclined so as to gradually approach the seat 20 in the direction away from the operating member 300. In this way, when the protector 10 is adjusted in a direction toward the seat 20, the need to operate the operating member 300 is eliminated, and the user can directly push the protector 10 in a direction toward the seat 20.

[0043] Alternatively, as shown in Figures 7, 13, and 15, one of the first connecting portion 21c and the second connecting portion 221 is a second male connecting portion, and the other of the first connecting portion 21c and the second connecting portion 221 is a second female connecting portion that is removably connected to the second male connecting portion.

[0044] In this embodiment, as shown in Figures 7, 13, and 15, the first connecting portion 21c is an engagement hole, and the second connecting portion 221 is an engagement hook that is detachably connected to the engagement hole. Attachment and detachment between the protector 10 and the seat 20 can be achieved through the detachable connection between the engagement hook and the engagement hole. In this way, the connection is stable, the structure is simple, and installation is easy. Alternatively, the first connecting portion 21c may be an engagement hook, and the second connecting portion 221 may be a corresponding engagement hole, but this is not limited thereto.

[0045] Optionally, as shown in Figures 1 and 9, two connection adjustment mechanisms 30 are provided. The slide tubes 100 of the two connection adjustment mechanisms 30 are fixed to both sides of the protector 10, respectively. The connection members of the two connection adjustment mechanisms 30 are detachably coupled to the two sides of the seat 20, which facilitates simultaneous position adjustment of the protector 10. The number of connection adjustment mechanisms 30 may be more than two, less than two, or more than two, and can be set according to actual needs and is not limited herein.

[0046] The connection adjustment mechanism 30 and the child carrier described above provide the following advantages.

[0047] The connection adjustment mechanism 30 is applicable to a child carrier. The slide tube 100 can be fixed to the protector 10, and the connecting member 220 can be removably connected to the seat 20. When the operating member 300 moves (slides or rotates) in the first direction D1, the connecting member 220 can move (slides or rotates) relative to the slide member 210. In this way, the connecting member 220 can be switched between a state engaged with the seat 20 and a state disengaged from the seat 20, thereby realizing a removably connected state between the protector 10 and the seat 20. When the operating member 300 moves (slides or rotates) in the second direction D2, the slide member 210 and the slide tube 100 can slide relative to each other. At this time, if the connecting member 220, which is swingably connected to the slide member 210, is in a connected state with the seat 20, the protector 10 can move toward or away from the seat 20 in association with the sliding of the slide tube 100. That is, it is possible to adjust the seating space between the protector 10 and the seat 20. In this way, the function of attaching and removing the protector 10 and the function of adjusting the seating space are achieved by a single operating member 300, which simplifies the structure and simplifies the operation.

[0048] In another embodiment, the function of the operating member 300 can be improved through two operating members. One of the two operating members is configured to drive the connecting member 220 so that the protector 10 and the seat 20 are connected to or separated from each other. The other of the two operating members is configured to drive the adjusting member 230 so that the seating space between the seat 20 and the protector 10 can be adaptively adjusted.

[0049] The technical features of the above embodiments can be combined in any manner. For the sake of simplicity, not all possible combinations of the technical features in the above embodiments are described. However, all combinations of these technical features should be considered within the scope of the present disclosure, provided that the combinations are not inconsistent with each other.

[0050] The above embodiments merely illustrate some embodiments of the present disclosure, and the description, although specific and detailed, should not be taken as a basis for limiting the scope of the present disclosure. It should be noted that a person skilled in the art can make some modifications and improvements without departing from the concept of the present disclosure, and all of these fall within the scope of protection of the present disclosure. Therefore, the scope of protection of the present disclosure shall be subject to the appended claims. [Explanation of symbols]
