Description

Technical Field

[0001] The present application relates to the technical field of infant products, and in particular to a connection structure and an infant carrier. Background Art

[0002] A car child safety seat, also known as a child restraint system (CRS), is a seat designed for children of different ages (or weights) and installed in a car to effectively improve the safety of children riding in a car. Usually, it is necessary to choose a suitable safety seat style according to the age or body shape of the child. For infants aged 0 to 1 year old (within about 10 kilograms), a bed-type safety seat, i.e., an infant safety carrier, is generally suitable, so that young infants can be ideally protected in a suitable special seat.

[0003] At present, common infant safety carriers generally consist of a carrier and a base assembly, wherein the base assembly is formed at the bottom of the carrier. When infants and young children need to ride in a car, the infant safety carrier is directly placed on the car seat and connected to the car seat through the base assembly. However, due to structural limitations, the above-mentioned infant safety carrier is heavy and not lightweight enough. When a user carries the infant safety carrier and walks, it is easy to make the user tired, which increases the walking burden. Summary of the invention

[0154] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0155] Figure 1 A perspective view of a baby carrier 1000 according to an embodiment of the present application is shown, and the baby carrier 1000 may include a baby carrier body 100 and a connection structure 200 according to an embodiment of the present application. The connection structure 200 will be described together with the baby carrier 1000 hereinafter.

[0156] See also Figures 1 to 5In one embodiment, the baby carrier body 100 is described by taking a baby safety carrier as an example. The baby safety carrier has a plurality of snap-fitting parts, one of which is used to be detachably connected to the connection structure 200 provided in one embodiment of the present application. According to the different setting positions of the snap-fitting parts, each snap-fitting part can be divided into a front snap-fitting part 101 and a rear snap-fitting part 102, wherein the front snap-fitting part 101 is located at the front end of the bottom of the baby safety carrier, and the rear snap-fitting part 102 is located at the rear end of the bottom of the baby safety carrier. The front snap-fitting part 101 and the rear snap-fitting part 102 are both rod-shaped. The baby safety carrier is detachably connected to the connection structure 200 provided in one embodiment of the present application through the front snap-fitting part 101, and the connection structure 200 can also be detachably connected to the car seat 2000, so that the baby safety carrier can be installed on the car seat 2000. Specifically, two mounting ribs 104 are provided at the bottom of the baby carrier body 100, and the two mounting ribs 104 are spaced apart in the left-right direction, so that a mounting groove 105 can be formed between the two mounting ribs 104, and the front engaging member 101 and the rear engaging member 102 are both located in the mounting groove 105, wherein the width of the mounting groove 105 at the front engaging member 101 is different from the width of the mounting groove 105 at the rear engaging member 102, so as to avoid confusion of the front and rear directions when the baby carrier body 100 is installed on a connecting structure such as a base. In this embodiment, the width of the mounting groove 105 at the front engaging member 101 is greater than the width of the mounting groove 105 at the rear engaging member 102. In other words, the length W3 of the front engaging member 101 is greater than the length W2 of the rear engaging member 102 (see Figure 4 ). It should be noted that the left and right directions here can refer to the second direction F2 described below. It should be noted that the above-mentioned "front end" and "rear end" are distinguished based on the lying position of the infant when the infant is lying in the infant safety carrier. For example, the "front end" refers to the end of the infant safety carrier where the infant's feet are placed, and the "rear end" refers to the end where the infant's head is placed.

[0157] In order to improve the safety of infants and young children riding in infant safety baskets, infant safety baskets are usually installed in reverse on the car seat 2000 (see Figure 5 ), it can be understood that when an infant is sitting in an infant safety carrier, the infant's face is facing away from the direction of the vehicle, which is equivalent to the face facing the rear of the vehicle. Figure 1 and Figure 5 As shown, the front end of the baby safety carrier is formed with an abutting inclined surface 103. When the baby safety carrier is installed on the car seat 2000, the abutting inclined surface 103 is used to abut against the backrest of the car seat 2000, which can improve the stability of the baby safety carrier installed on the car seat 2000. Of course, in another embodiment, such as Figure 33 to Figure 35As shown, a push-up member 106 is provided at the front end of the infant safety carrier. The front end of the push-up member 106 has a vertical abutting surface 1061, which is used to abut against the backrest of the car seat 2000 (see Fig.36 and Fig.37 In this way, the contact area between the baby safety carrier and the backrest of the car seat 2000 is increased, preventing the baby safety carrier from flipping backward relative to the car seat 2000, thereby improving the safety of the baby safety carrier.

[0158] See also Figure 5 , an embodiment of the present application provides a connection structure 200, which is used to connect an infant carrier body 100 (for example, an infant safety carrier) to a car seat 2000. Specifically, as Figures 2 to 4 As shown, the connection structure 200 may include a base assembly 20, a first connection mechanism 40 and a second connection mechanism 50. The first connection mechanism 40 and the second connection mechanism 50 are respectively connected to the base assembly 20, and the first connection mechanism 40 is used to be detachably connected to the car seat 2000, and the second connection mechanism 50 is used to be detachably connected to the front engaging member 101 on the infant carrier body 100. Further, the shape of the second connection mechanism 50 is configured to be suitable for connecting to the front engaging member 101. In this embodiment, in order to avoid the problem of misconnection (for example, connecting the rear engaging member 102 to the second connection mechanism 50), in one embodiment, the width W1 of the second connection mechanism 50 along the left-right direction (that is, the width W1 of the base assembly 20 along the left-right direction at the second connection mechanism 50) is greater than the length W2 of the rear engaging member 102 along the left-right direction (see Figure 4 ), so that the rear engaging member 102 cannot be connected to the second connecting mechanism 50. It should be noted that in another embodiment, the second connecting mechanism 50 can be engaged with the rear engaging member 102; or, in some other embodiments, the second connecting mechanism 50 can be engaged with any one of the front engaging member 101 and the rear engaging member 102, which is not limited in this application.

[0159] In the above-mentioned connection structure 200, since the first connection mechanism 40 can be detachably connected to the car seat 2000, and the second connection mechanism 50 can be detachably connected to the front engaging member 101 on the baby carrier body 100, when the baby carrier body 100 needs to be installed on the car seat 2000, the baby carrier body 100 can be directly connected to the base assembly 20 through the second connection mechanism 50, and then the base assembly 20 can be connected to the car seat 2000 through the first connection mechanism 40; or, the base assembly 20 can be first connected to the car seat 2000 through the first connection mechanism 40, and then the baby carrier body 100 can be connected to the base assembly 20 through the second connection mechanism 50 to achieve the connection between the baby carrier body 100 and the car seat 2000. In addition, when the baby carrier body 100 needs to be carried alone, the baby carrier body 100 can be directly separated from the base assembly 20 without carrying the entire connecting structure 200 , which can effectively reduce the burden on the user when carrying the baby carrier body 100 .

[0160] See also Figure 6 and Figure 7 In one embodiment, the base assembly 20 includes a first base 201 and a second base 202 that can slide back and forth relative to the first base 201. Specifically, the second base 202 is slidably mounted outside the first base 201. Of course, in another alternative embodiment, the first base 201 is slidably mounted outside the second base 202. Of course, in another embodiment, the first base 201 is fixedly connected to the second base 202, and the two cannot slide relative to each other. Figure 6 and Figure 7 In one embodiment, the first connecting mechanism 40 is connected to the first base 201, and the second connecting mechanism 50 is connected to the second base 202. In this way, the length of the base assembly 20 along the front-to-back direction (which can be regarded as the first direction F1) can be adjusted by sliding the second base 202 relative to the first base 201, so that the connecting structure 200 can adapt to car seats 2000 of different sizes. Of course, in another alternative embodiment, the first connecting mechanism 40 is connected to the second base 202, and the second connecting mechanism 50 is connected to the first base 201. Specifically, in this embodiment, Figure 6 and Figure 7 The second base 202 is shown to be sleeved outside the first base 201, and the first connecting mechanism 40 is connected to the first base 201, and the second connecting mechanism 50 is connected to the second base 202. In one embodiment, Figure 1 and Figure 4As shown, in order to make the structure of the base assembly 20 more compact, the width of the second base 202 of the base assembly 20 is smaller than the width of the mounting groove 105 of the baby carrier body 100. When the connecting structure 200 is connected to the front engaging member 101 of the baby carrier body 100, the second base 202 of the base assembly 20 is engaged in the mounting groove 105 of the baby carrier body 100. At this time, the two mounting ribs 104 at the bottom of the baby carrier body 100 are respectively located on both sides of the second base 202 (see FIG. Figure 1 ).

[0161] Of course, in another embodiment, if Fig.33 , Fig.38 and Fig.40 As shown, the width of the second base 202 can be greater than the width of the mounting groove 105 of the baby carrier body 100, or the width of the second base 202 can be greater than the width of the baby carrier body 100. Specifically, two receiving grooves 204 are provided on the second base 202, and the two receiving grooves 204 are respectively located on both sides of the second connecting mechanism 50. Therefore, when the connecting structure 200 is connected to the front engaging member 101 of the baby carrier body 100, the middle part of the second base 202 of the base assembly 20 (i.e., the part where the second connecting mechanism 50 is provided) is engaged in the mounting groove 105, and the two mounting ribs 104 are respectively accommodated in the two receiving grooves 204 (see Fig.33 ). In this way, the contact area between the baby carrier body 100 and the base assembly 20 can be increased, and the stability of the support for the baby carrier body 100 can be improved. It should be noted that, unless otherwise specified, the directional terms such as "front" and "rear" in the embodiments of the present application are based on the directions shown in the figures. The arrows B and P in each figure indicate the forward and rear directions respectively. These directional terms are only used to make the description of the embodiments of the present application clearer, and are not used to improperly limit the scope of protection of the present application. Specifically, the front and rear directions in the present embodiment can specifically refer to the directions of the car when it is driving normally.

[0162] See also Figures 6 to 9 The first base 201 includes a first upper shell 201A and a first lower shell 201B that are buckled together, and the first upper shell 201A and the first lower shell 201B are enclosed to form a first chamber 201C with an opening. The second base 202 includes a second upper shell 202A and a second lower shell 202B that are buckled together, and the second upper shell 202A and the second lower shell 202B are enclosed to form a second chamber 202C with an opening, and the first chamber 201C and the second chamber 202C are connected through the opening to form a receiving chamber 203.

[0163] See also Figures 8 to 11In one embodiment, the base assembly 20 further includes a fixed frame 210 and a sliding frame 220. The fixed frame 210 and the sliding frame 220 are both contained in the accommodating cavity 203, the fixed frame 210 is connected to the first base 201, and the sliding frame 220 is connected to the second base 202 and is slidably connected to the fixed frame 210. The sliding frame 220 can slide forward and backward relative to the fixed frame 210. Of course, in another alternative embodiment, the fixed frame 210 is connected to the second base 202, and the sliding frame 220 is connected to the first base 201. In this way, the relative position between the sliding frame 220 and the fixed frame 210 can be changed, thereby changing the relative position between the second base 202 and the first base 201, which is equivalent to changing the length of the base assembly 20 in the front-to-back direction (first direction F1).

[0164] See also Figure 8 and Fig. 9 In one embodiment, the fixed frame 210 can be detachably or fixedly disposed in the first chamber 201C; the sliding frame 220 can be detachably or fixedly disposed in the second chamber 202C.

[0165] Continue to see Figure 8 and Fig. 9 In one embodiment, one of the sliding frame 220 and the fixed frame 210 is provided with a plurality of locking portions 221, and the plurality of locking portions 221 are sequentially spaced apart along the sliding direction (i.e., the front-to-back direction) of the sliding frame 220. The base assembly 20 also includes a first locking member 230, which is movably supported on the other of the sliding frame 220 and the fixed frame 210 to allow the first locking portion 231 of the first locking member 230 to engage with and disengage from the locking portion 221. The locking portion 221 is, for example, a locking hole or a locking tooth. Specifically, in this embodiment, the locking portion 221 is taken as an example of a locking hole. When a plurality of locking holes 221 are provided on the sliding frame 220 (see for details), Fig.12 and Fig.13 ), the first locking member 230 is pivotally disposed on the fixed frame 210. Alternatively, when the fixed frame 210 is provided with a plurality of locking holes 221, the first locking member 230 is pivotally disposed on the sliding frame 220. Figures 10 to 13 The sliding frame 220 is provided with a plurality of locking holes 221, and the first locking member 230 is pivotally disposed on the fixing frame 210. Specifically, as Fig.10 and Fig.11 As shown, the first locking portion 231 has a guide slope 2311 (see Fig.15), the guiding inclined surface 2311 faces forward. When the first locking member 230 is engaged with the locking hole, that is, when the first locking member 230 extends into the locking hole, the first locking portion 231 of the first locking member 230 can limit the forward extension movement of the sliding frame 220 relative to the fixed frame 210, and the guiding inclined surface 2311 of the first locking portion 231 can be pushed by the edge of the locking hole 221 so that the first locking portion 231 exits the locking hole 221, thereby allowing the sliding frame 220 to retract backward relative to the fixed frame 210. In other words, when the first locking portion 231 of the first locking member 230 is inserted into the locking hole 221, under the action of the guiding slope 2311, the sliding frame 220 (i.e. equivalent to the second base 202) can be allowed to move backward relative to the fixed frame 210 (i.e. equivalent to the first base 201), thereby shortening the length of the base assembly 20 along the front-to-back direction (the first direction F1), but the sliding frame 220 (i.e. equivalent to the second base 202) is not allowed to move forward relative to the fixed frame 210 (i.e. equivalent to the first base 201), thereby limiting the increase in the length of the base assembly 20 along the front-to-back direction (the first direction F1).

[0166] Specifically, in this embodiment, Fig.10 and Fig.11 As shown, the first locking member 230 is pivotally connected to the fixing frame 210, and the guiding inclined surface 2311 faces forward.

[0167] In order to improve the convenience of adjusting the length of the base assembly 20 along the front-to-back direction (first direction F1), as shown in FIG. Figures 8 to 11 As shown, in one embodiment, the base assembly 20 may further include a first release mechanism 240. The first release mechanism 240 is operably connected to the first locking member 230, and is used to drive the first locking portion 231 of the first locking member 230 to exit from the locking hole 221. In this way, after the first locking portion 231 exits the locking hole 221, the sliding between the sliding frame 220 and the fixed frame 210 is not restricted, and the sliding frame 220 (equivalent to the second base 202) can be pushed to move forward relative to the fixed frame 210 (equivalent to the first base 201) to increase the length of the base assembly 20.

[0168] See also Fig.10 and Fig.11 In one embodiment, the first release mechanism 240 may include a driving member 241. The driving member 241 is slidably disposed in the fixing frame 210 and has a first position and a second position, and the driving member 241 is provided with a driving inclined surface 2411 (see Fig.16 Specifically, the driving member 241 slides on the fixing frame 210 along the front-to-back direction (the first direction F1). The fixing frame 210 is provided with a first guide hole 214 (see Fig.14 ), the driving member 241 is provided with a guide post 2412 (see Fig.16), the guide column 2412 is slidably matched with the first guide hole 214 to guide the movement of the driving member 241. More specifically, the first locking member 230 is pivotally connected to the fixing frame 210 and has a locking position and an unlocking position. The first locking member 230 also has a driving portion 232, and the driving portion 232 is used to abut against the driving inclined surface 2411 and slide along the driving inclined surface 2411, so that the first locking member 230 can switch between the locking position and the unlocking position. More specifically, when the driving member 241 is located in the first position, the first locking member 230 is located in the locking position and is in a locked state. When the driving member 241 moves from the first position to the second position, the driving portion 232 slides along the driving inclined surface 2411, thereby driving the first locking member 230 to pivot from the locking position to the unlocking position. When the driving member 241 is located at the second position, the first locking member 230 is located at the unlocking position, and the first locking portion 231 exits the locking hole 221 to allow the sliding frame 220 to move forward relative to the fixing frame 210 .

[0169] To facilitate the control of the driving member 241 switching between the first position and the second position, in one embodiment, Figure 8 and Fig. 9 As shown, the first release mechanism 240 may further include a first operating member 242, a linkage assembly 243 and a first traction assembly 244. Specifically, the first operating member 242 is operably disposed on the second base 202. The linkage assembly 243 is at least partially located in the first base 201 and connected to the driving member 241. The first traction assembly 244 is connected to the first operating member 242 and the linkage assembly 243, respectively. More specifically, when the first operating member 242 is operated, the first operating member 242 can drive the driving member 241 to move from the first position to the second position through the first traction assembly 244 and the linkage assembly 243.

[0170] See also Figure 8 and Fig. 9 In one embodiment, the first operating member 242 is movably disposed on the second base 202, and the moving direction of the first operating member 242 is parallel to the moving direction of the driving member 241, that is, the first operating member 242 can move along the front-to-back direction (first direction F1) on the second base 202.

[0171] Specifically, Figure 3 and Figure 4 As shown, the second base 202 is provided with an operation hole 2021, and the operation hole 2021 is located on a side of the second base 202 away from the first base 201. Figure 8 and Fig. 9 As shown, the first operating member 242 passes through the operating hole 2021 and is connected to the first traction sleeve 2442 .

[0172] Continue to see Figure 8 and Fig. 9 In one embodiment, the first traction assembly 244 includes a first traction rope 2441 and a first traction sleeve 2442 movably sleeved outside the first traction rope 2441. The first traction sleeve 2442 has a first sleeve end 24421 and a second sleeve end 24422, and the first traction rope 2441 has a first rope end (not shown) adjacent to the first sleeve end 24421 and a second rope end 24412 adjacent to the second sleeve end 24422. Specifically, the first rope end of the first traction rope 2441 is connected to the second base 202, and the second rope end 24412 of the first traction rope 2441 is connected to the linkage assembly 243. The first sleeve end 24421 of the first traction sleeve 2442 is connected to the first operating member 242, and the second sleeve end 24422 of the first traction sleeve 2442 is connected to the first base 201. When the first operating member 242 is operated, the first traction sleeve 2442 is bent and deformed so that the first traction rope 2441 drives the driving member 241 to move from the first position to the second position by pulling the linkage assembly 243 .

[0173] Specifically, in this embodiment, the first traction sleeve 2442 is a bendable wire sleeve. It should be noted that the first traction sleeve 2442 can be made of a hard but bendable material, such as a bendable tubular structure made of a metal material (such as steel) or a plastic (such as PVC).

[0174] In one embodiment, if Fig.14 As shown, the fixing frame 210 is provided with an avoidance hole 211, and the avoidance hole 211 extends along the sliding direction of the driving member 241. Figure 8 and Fig. 9 As shown, the linkage assembly 243 includes a linked linkage block 2431 and a linkage rod 2432. The second rope end 24412 of the first traction rope 2441 is connected to the linkage block 2431, and the linkage rod 2432 passes through the avoidance hole 211 and is drivingly connected to the driving member 241, so as to allow the first traction assembly 244 to drive the linkage block 2431 to move through the second rope end 24412, and then drive the driving member 241 to move through the linkage rod 2432.

[0175] In one embodiment, if Fig.17 As shown, the first operating member 242 is provided with a first fixing portion 2421 and a second guide hole 2422. Figure 8 and Fig. 9As shown, the first fixing portion 2421 is used to connect the first sleeve end 24421 of the first traction sleeve 2442. The second guide hole 2422 extends along the moving direction of the first operating member 242. More specifically, a column 245 is provided in the second chamber 202C, and the column 245 is inserted into the second guide hole 2422. Through the guiding cooperation between the column 245 and the second guide hole 2422, the first operating member 242 can be prevented from shifting during movement. In this embodiment, the number of the second guide holes 2422 is two, and the two second guide holes 2422 are distributed on both sides of the first fixing portion 2421. The column 245 is formed by a threaded connector (for example, a screw, a bolt, etc.) connected to the second base 201. The number of the columns 245 is two, and the two columns 245 are respectively guided and cooperated with the corresponding second guide holes 2422.

[0176] See also Figure 8 and Fig. 9 In one embodiment, the first release mechanism 240 further includes a first reset member 250, which abuts against the linkage assembly 243 and is used to drive the linkage assembly 243 to reset so that the driving member 241 remains in the first position. The first reset member 250 is, for example, a spring, which is sleeved outside the first traction rope 2441 and abuts between the linkage block 2431 and the second sleeve end 24422. Further, in one embodiment, the first release mechanism 240 further includes an operating reset member (not shown in the figure), which abuts against the first operating member 242 and is used to drive the first operating member 242 to reset.

[0177] Continue to see Figure 8 and Fig. 9 In one embodiment, the base assembly 20 further includes a second reset member 260, which abuts between the fixing frame 210 and the first locking member 230 and is used to drive the first locking member 230 to reset so that the first locking member 230 remains in the locked position. The second reset member 260 is, for example, a torsion spring, which is sleeved on the first connecting member 223 and abuts between the fixing frame 210 and the first locking member 230.

[0178] Combine the following Figures 8 to 11 The working principle and process of the first unlocking mechanism 240 are described below.

[0179] See also Fig.10 Specifically, when it is necessary to reduce the length of the base assembly 20 along the front-to-back direction, the user can directly push the second base 202 backwards, and the edge of the locking hole 221 pushes the guide slope 2311 of the first locking portion 231 to make the first locking portion 231 exit the locking hole 221, thereby allowing the sliding frame 220 to retract backward relative to the fixed frame 210, thereby shortening the length of the base assembly 20 along the front-to-back direction (first direction F1).

[0180] See also Figure 8 and Fig. 9 When the length of the base assembly 20 along the front-to-back direction needs to be increased, the user needs to push the first operating member 242 backward along the front-to-back direction. When the first operating member 242 moves backward, it will drive the first sleeve end 24421 of the first traction sleeve 2442 to move together, so that the first traction sleeve 2442 bends, and thus the first traction rope 2441 bends along with the first traction sleeve 2442. Since the first rope end of the first traction rope 2441 is fixed, when the first traction rope 2441 bends, the distance between the first rope end and the second rope end 24412 is shortened, so that the second rope end 24412 moves toward the first rope end (that is, the second rope end 24412 moves forward along the front-to-back direction). In other words, when the first operating member 242 moves backward, it will drive the first sleeve end 24421 of the first traction sleeve 2442 to move together, and the distance between the first sleeve end 24421 and the first rope end will be longer. The length of the first traction rope 2441 between the first sleeve end 24421 and the second sleeve end 24422 remains unchanged, so the distance between the second sleeve end 24422 and the second rope end 24412 is shortened, which is equivalent to the second rope end 24412 moving forward in the front-to-back direction. In this way, the linkage assembly 243 can be driven to move forward in the front-to-back direction through the second rope end 24412, which is also regarded as driving the driving member 241 forward, so that the driving member 241 moves from the first position to the second position. Since the driving inclined surface 2411 is against the driving portion 232, when the driving member 241 moves forward, the first locking member 230 can be rotated counterclockwise around the first connecting member 223 (by Fig.10 The status of Fig.11 The first locking portion 231 is withdrawn from the locking hole 221, which is equivalent to the first locking member 230 being switched from the locking position (see Fig.10 ) to the unlocked position (see Fig.11 At this time, the relative movement between the sliding frame 220 and the fixed frame 210 is not restricted, and the length of the base assembly 20 can be freely adjusted, for example, the length of the base assembly 20 can be increased.

[0181] When the moving position of the sliding frame 220 relative to the fixed frame 210 is confirmed, which is equivalent to the moving position of the second base 202 relative to the first base 201 being confirmed, the first operating member 242 is released, and the first reset member 250 is reset to push the linkage assembly 243 to move backward along the front-to-back direction, thereby causing the driving member 241 to move backward, which is equivalent to causing the driving member 241 to move from the second position to the first position. At this time, under the action of the second reset member 260, the first locking member 230 can rotate clockwise around the first connecting member 223 (by Fig.11 The status of Fig.10The first locking portion 231 extends into the locking hole 221, which is equivalent to switching the first locking member 230 from the unlocking position (see Fig.11 ) to the locked position (see Fig.10 At this time, the sliding frame 220 is allowed to move backward relative to the fixed frame 210 (i.e., shorten the length of the base assembly 20), while the sliding frame 220 is restricted from moving forward relative to the fixed frame 210 (i.e., restricting the increase in the length of the base assembly 20).

[0182] See also Fig.41 and Fig.42 In other embodiments, the first release mechanism 240 includes a driving member 241, a first operating member 242 and a linkage assembly 243. Fig.41 and Fig.42 ) and the above embodiment (see Fig.10 and Fig.11 )There are at least the following differences.

[0183] like Fig.41 and Fig.42As shown, in another embodiment, the first base 201 (such as the first lower shell 201B) is provided with an operating hole 2021, and the first operating member 242 is movably arranged at the operating hole 2021, and the moving direction of the first operating member 242 is the same as the moving direction of the driving member 241, that is, it moves along the front-to-back direction (first direction F1). The linkage assembly 243 is located in the first base 201 (first chamber 201C) and is connected between the first operating member 242 and the driving member 241. Therefore, when the first operating member 242 is operated, for example, when the first operating member 242 is pushed and pulled along the front-to-back direction, the first operating member 242 drives the linkage assembly 243 to move, so as to drive the driving member 241 to move from the first position to the second position. It should be noted that, in this embodiment, the linkage assembly 243 can only include the linkage rod 2432. In this embodiment, the first release mechanism 240 further includes a first reset member 250, which abuts against the driving member 241 and is used to drive the driving member 241 to reset so that the driving member 241 remains in the first position. Specifically, the first reset member 250 is, for example, a spring. The driving member 241 is provided with a driving groove 2413, and the extending direction of the driving groove 2413 is substantially the same as the moving direction of the driving member 241, that is, the driving groove 2413 extends along the front-to-back direction (first direction F1). The fixed frame 210 is provided with an abutting portion 215, and the abutting portion 215 at least partially extends into the driving groove 2413. The first reset member 250 is arranged in the driving groove 2413, one end of the first reset member 250 abuts against the abutting portion 215, and the other end of the first reset member 250 abuts against the inner side wall of the driving groove 2413 away from the driving inclined surface 2411. In this way, the first reset member 250 pushes the driving member 241 to move backward along the front-to-back direction. The first unlocking mechanism 240 in this embodiment has a simple structure and is relatively convenient to operate.

[0184] Continue to see Fig.41 and Fig.42 In another embodiment, the base assembly 20 further includes an elastic member 350. A first stopper 206 is provided in the first base 201, and a second stopper 207 is provided in the second base 202. The elastic member 350 abuts between the first stopper 206 and the second stopper 207, so that the first base 201 and the second base 202 have a tendency to move away from each other. In this way, when the first locking portion 231 of the first locking member 230 withdraws from the locking hole 221, the relative movement between the sliding frame 220 and the fixing frame 210 is not restricted. Therefore, under the push action of the elastic member 350, the second base 202 can directly slide relative to the first base 201, so that the length of the base assembly 20 can be automatically increased.

[0185] Specifically, Fig.41 and 42As shown, at least one of the first stopper 206 and the second stopper 207 is provided with a guide rod 208. The elastic member 350 is, for example, a compression spring, and the elastic member 350 is sleeved outside the guide rod 208, and both ends of the elastic member 350 are respectively in contact with the first stopper 206 and the second stopper 207. In this way, when the sliding frame 220 moves relative to the fixing frame 210 to reduce the length of the base assembly 20, the guide rod 208 can prevent the elastic member 350 from being deflected or bent during the compression process.

[0186] like Fig.10 and Fig.11 As shown, in one embodiment, in order to prevent the sliding frame 220 from deviating when it moves relative to the fixed frame 210, and to prevent the two from being separated due to sliding transition, the sliding frame 220 is provided with a first limiting groove 222, the first limiting groove 222 extends along the sliding direction of the sliding frame 220, and a first connecting member 223 for connecting the fixed frame 210 is slidably arranged in the first limiting groove 222. The first locking member 230 is pivotally connected to the fixed frame 210 through the first connecting member 223. In this embodiment, the fixed frame 210 is further provided with a second limiting groove 212, the second limiting groove 212 extends along the sliding direction of the sliding frame 220, and a second connecting member 213 for connecting the sliding frame 220 is slidably arranged in the second limiting groove 212. In this way, the sliding frame 220 can slide more stably relative to the fixed frame 210, and further prevent the sliding frame 220 from shaking or deviating when it moves relative to the fixed frame 210. In this embodiment, the second connecting member 213 is located at a position slightly above the rear side of the first connecting member 223 (i.e., located at a rear upper position of the first connecting member 213). The first locking portion 231 of the first locking member 230 is located at the rear side of the first connecting member 223, and at least a portion of the first locking member 230 is located below the second connecting member 213. When the first locking member 230 is located at the locking position, the first locking member 230 is spaced apart from the second connecting member 213. When the first locking member 230 is pushed by the driving member 241 and pivoted to the unlocking position, the first locking member 230 is stopped by the second connecting member 213, thereby limiting the further pivoting of the first locking member 230, and further limiting the moving stroke of the driving member 241.

[0187] See also Figure 8 and Fig. 9In one embodiment, two sliding frames 220 and two fixed frames 210 are provided in the accommodating cavity 203, and the two correspond to each other one by one and are slidably connected. Specifically, the two fixed frames 210 are arranged at intervals along the left-right direction (which can be regarded as the second direction F2). The second direction F2 is not parallel to the first direction F1, and more specifically, the second direction F2 is substantially perpendicular to the first direction F1. Further, the number of the first locking member 230 and the driving member 241 are both two, and each fixed frame 210 is pivotally connected to a first locking member 230, and each fixed frame 210 is provided with a driving member 241. More specifically, the first operating member 242, the linkage assembly 243 and other components are arranged between the two fixed frames 210, and the two ends of the linkage rod 2432 are respectively drivingly connected to the two driving members 241. Thus, when the first operating member 242 is pushed, the two driving members 241 can be switched from the first position to the second position at the same time under the action of the linkage assembly 243, which is equivalent to driving the two first locking members 230 to switch from the locked position to the unlocked position at the same time.

[0188] It should be noted that, unless otherwise specified, the directional terms such as "left" and "right" in the embodiments of the present application are based on the directions shown in the figures. The left and right directions are indicated by arrows L and R in each figure, respectively. These directional terms are only used to make the description of the embodiments of the present application clearer and are not used to improperly limit the scope of protection of the present application. Specifically, the left and right directions in the present embodiment can specifically refer to the width direction of the car.

[0189] See also Figure 5 As shown, when the aforementioned connection structure 200 is used, the base assembly 20 can be first installed on the car seat 2000 of the car through the first connection mechanism 40. Subsequently, the first locking member 230 can be switched to the unlocked position by manipulating (such as pressing or pushing) the first operating member 242, thereby releasing the restriction on the sliding frame 220, and the second base 202 can move forward relative to the first base 201, so that the length of the base assembly 20 is at a larger value, thereby leaving a larger operating space between the base assembly 20 and the backrest of the car seat 2000, so as to quickly install the baby carrier body 100 on the base assembly 20 through the second connection mechanism 50. After the baby carrier body 100 is installed on the base assembly 20, the position of the baby carrier body 100 can be adjusted through the base assembly 20 according to actual conditions. For example, when the baby carrier body 100 needs to be moved backward so that the abutting inclined surface 103 of the baby carrier body 100 can abut against the backrest of the car seat 2000, the second base 202 can be directly pushed backward. It can be seen that when the base assembly 20 is a retractable structure, it is conducive to the rapid installation of the baby carrier body 100, and at the same time, the connection structure 200 can be adapted to car seats 2000 of different sizes.

[0190] See also Fig.18 and Fig.19 or Fig.34 and Fig.35 In one embodiment, the first connecting mechanism 40 can be movably connected to the base assembly 20 and has an expanded state and a folded state. When the first connecting mechanism 40 is in the expanded state, the projection length of the connecting structure 200 on the horizontal plane is greater than the projection length of the connecting structure 200 on the horizontal plane when the first connecting mechanism 40 is in the folded state. In this embodiment, the horizontal plane is roughly parallel to the front-to-back direction (i.e., the first direction F1) and parallel to the left-to-right direction (i.e., the second direction F2 hereinafter). Of course, when the first connecting mechanism 40 is in the folded state, the first connecting mechanism 40 will overlap with the base assembly 20 in the first direction F1; when the first connecting mechanism 40 is in the expanded state, the first connecting mechanism 40 protrudes from the base assembly 20 in the first direction. Of course, in other embodiments, the first connecting mechanism 40 is fixedly mounted on the base assembly 20.

[0191] It should be noted that the above-mentioned "movable" may refer to the first connecting mechanism 40 being pivotally connected to the base assembly 20 so that the first connecting mechanism 40 has an unfolded state and a folded state; or it may refer to the first connecting mechanism 40 being telescopically connected to the base assembly 20 so that the first connecting mechanism 40 has an unfolded state and a folded state.

[0192] See also Figure 8 , Fig. 9 or Fig.21 , Fig. 22 In one embodiment, the first connecting mechanism 40 may include a plug connecting component 410 and at least one connecting plug 420. The plug connecting component 410 is pivotally connected to the base assembly 20, specifically, pivotally connected to the first base 201. The connecting plug 420 is fixedly connected to the plug connecting component 410, and is mainly used for detachable connection with the car seat 2000. Specifically, two connecting plugs 420 are provided, and the two connecting plugs 420 are respectively arranged at both ends of the plug connecting component 410. More specifically, in one embodiment, when the first connecting mechanism 40 is in the unfolded state, the angle α1 between the connecting plug 420 and the base assembly 20 is substantially 180 degrees (see Figure 8 and Fig.18 or Fig.34 and Fig.38 When the angle α1 is about 180 degrees, the connecting structure 200 is mainly used to install the baby carrier body 100 on the car seat 2000 with the seat surface in a horizontal state (the installation situation can be seen later). Of course, when the first connecting mechanism 40 is in the unfolded state, the angle α1 can also be greater than 180 degrees, for example, 200 degrees, 220 degrees, etc. (see Fig.37When the angle α1 is greater than 180 degrees, the connection structure 200 is mainly used to install the baby carrier body 100 on the car seat 2000 with the seat surface in an inclined state (the installation situation can be seen later). When the first connection mechanism 40 is in the folded state, the angle α1 between the connection plug 420 and the base assembly 20 is substantially 0 degrees (see Fig.19 or Fig.35 Thus, when the connecting structure 200 is used to install the baby carrier body 100 on the car seat 2000, the first connecting mechanism 40 is directly unfolded to be in the unfolded state (see FIG. Fig.18 or Fig.34 ), and then the connection between the baby carrier body 100 and the car seat 2000 is realized through the first connection mechanism 40 and the second connection mechanism 50. When the connection structure 200 needs to be carried together with the baby carrier body 100, the connection between the baby carrier body 100 and the base assembly 20 can be maintained, and then the connection plug 420 is rotated to rotate the plug connection component 410 in the first base 201 by nearly 180 degrees, so that the first connection mechanism 40 is in a folded state, which can be regarded as folded on the baby carrier body 100 (see Fig.19 or Fig.35 ), which makes it easy to carry.

[0193] See also Fig. 20 In one embodiment, the first connecting mechanism 40 also has a half-folded state. When the first connecting mechanism 40 is in the half-folded state, the angle α1 between the connecting plug 420 and the base assembly 20 is an acute angle, and the base assembly 20 abuts against the backrest of the car seat 2000. After the baby carrier body 100 is separated from the connecting structure 200, the base assembly 20 can be rotated so that the base assembly 20 and the plug connecting component 410 are relatively rotated until the angle α1 between the connecting plug 420 and the base assembly 20 is an acute angle, which can reduce the occupied area of ​​the connecting structure 200 on the car seat 2000, thereby not affecting the normal use of the car seat 2000.

[0194] As can be seen from the above description, the first connecting mechanism 40 has a first pivot position, a second pivot position, a third pivot position and a fourth pivot position relative to the base assembly 20. And the first connecting mechanism 40 can also remain locked at each pivot position, that is, the first connecting mechanism 40 can be locked at the first pivot position, the second pivot position, the third pivot position and the fourth pivot position. Specifically, when the first connecting mechanism 40 is at the first pivot position (see Fig.19 ), the first connecting mechanism 40 is in a folded state, at which the angle α1 is about 0 degrees. When the first connecting mechanism 40 is in the second pivot position (see Fig.18 or Fig.36 or Fig.50), the first connecting mechanism 40 is in the unfolded state, and the angle α1 is about 180 degrees. When the first connecting mechanism 40 is in the third pivot position (see Fig.37 or Fig.51 ), the first connecting mechanism 40 is in the unfolded state, the first connecting mechanism 40 is not parallel to the extension direction of the base assembly 20, and the angle α1 is greater than 180 degrees. Fig. 20 ), the first connecting mechanism 40 is in a half-folded state, and the base assembly 20 is suitable for abutting against the backrest of the automobile seat 2000, and the angle α1 is greater than 180 degrees.

[0195] See also Fig.21 In one embodiment, the base assembly 20 has a second locking member 270. The second locking member 270 is used to limit the first connecting mechanism 40 to an expanded state or a folded state.

[0196] See also Figure 21 to Figure 24 In one embodiment, a stop groove 430 is provided on the plug connection assembly 410, and the second locking member 270 is a stop convex. The second locking member 270 is movably arranged relative to the plug connection assembly 410, so that the second locking member 270 has a third position extending into the stop groove 430 and a fourth position retracted from the stop groove 430. Specifically, in this embodiment, the plug connection assembly 410 includes a connector 411 and two connecting inner tubes 412 fixedly connected to both ends of the connector 411. Among them, the two connecting inner tubes 412 are connected to the connector 411 by fasteners such as screws. Specifically, the connector 411 and the connecting inner tubes 412 connected to both ends of the connector 411 can be rotatably arranged in the first base 201. More specifically, the connector 411 can rotate about the rotation axis XX. The connector 411 is provided with a stop groove 430, and the second locking member 270 is movably arranged relative to the connector 411. One end of each connecting inner tube 412 away from the connector 411 is connected to the corresponding connecting plug 420. In one or more embodiments, the second locking member 270 may be a limiting groove, and the plug connection assembly 410 may include only one complete connecting inner tube, and a limiting protrusion is provided in the middle of the connecting inner tube.

[0197] In one embodiment, if Fig.21 and Fig.24As shown, the limiting groove 430 includes a first groove body 431 and a second groove body 432, and the first groove body 431 and the second groove body 432 are arranged opposite to each other. When the second locking member 270 extends into the first groove body 431, the first connecting mechanism 40 is limited to the expanded state. When the second locking member 270 extends into the second groove body 432, the first connecting mechanism 40 is limited to the folded state. Of course, in another embodiment, when the second locking member 270 extends into the first groove body 431, the first connecting mechanism 40 is limited to the folded state, and when the second locking member 270 extends into the second groove body 432, the first connecting mechanism 40 is limited to the expanded state.

[0198] See also Fig.21 In one embodiment, the base assembly 20 further includes a third reset member 280, which abuts against the second locking member 270 and is used to drive the second locking member 270 to remain in the third position. The third reset member 280 is, for example, a spring, which abuts against the second locking member 270.

[0199] See also Fig.24 In one embodiment, the edges of the first slot body 431 and the second slot body 432 are respectively provided with a guiding slope 433 to allow the second locking member 270 to exit the first slot body 431 or the second slot body 432 along the guiding slope 433. In this way, when the user needs to change the state of the first connecting mechanism 40, that is, switch from the folded state to the unfolded state or from the unfolded state to the folded state, there is no need to release the lock, and the connecting plug 420 can be directly rotated, so that the connecting plug 420 drives the connecting inner tube 412 and the connector 411 to rotate around the rotation axis XX, thereby improving the convenience of switching between the states. In addition, after the baby carrier body 100 is installed on the car seat 2000 through the connecting structure 200, if the car accelerates suddenly, the baby carrier body 100 and the base assembly 20 have a tendency to tip backward in the clockwise direction under the action of the inertia force. At this time, under the action of the guiding inclined surface 433, the second locking member 270 can withdraw from the first groove 431, and the base assembly 20 forms a tendency to rotate around the rotation axis XX relative to the connecting inner tube 412 and the connector 411, thereby preventing the baby carrier body 100 from being separated from the base assembly 20 due to the separation of the second connecting mechanism 50 when the baby carrier body 100 tips backward.

[0200] See also Fig.21 and Fig. 22In one embodiment, the plug connection assembly 410 further includes a connection outer tube 413 and a rotation locking mechanism 415. The connection outer tube 413 is sleeved outside the connection inner tube 412 and fixedly connected to the base assembly 20, and the connection inner tube 412 can rotate relative to the connection outer tube 413. The tube wall of the connection outer tube 413 is provided with an insertion hole for the second locking member 270 to pass through, and the second locking member 270 can extend into the first groove body 431 or the second groove body 432 after passing through the insertion hole. The rotation locking mechanism 415 is connected between the connection inner tube 412 and the connection outer tube 413, and the rotation locking mechanism 415 has a locking state and a release state. When the rotation locking mechanism 415 is in the locking state, the connection inner tube 412 is restricted from rotating relative to the connection outer tube 413, and when the rotation locking mechanism 415 is in the release state, the connection inner tube 412 is allowed to rotate relative to the connection outer tube 413. The rotation locking mechanism 415 includes a second locking member 270 disposed on the connecting inner tube 412 and a second matching portion 4131 disposed on the connecting outer tube 413. The second locking member 270 can be locked and matched with the second matching portion 4131 to limit the connecting inner tube 412 from rotating relative to the connecting outer tube 413. How the second locking member 270 and the second matching portion 4131 are locked and matched will be described in detail below, and will not be repeated here.

[0201] See also Fig.21 and Fig.25 In one embodiment, the plug connection assembly 410 further includes a wear-resistant sleeve 414. The wear-resistant sleeve 414 is sleeved between the connecting outer tube 413 and the connecting inner tube 412. The wear-resistant sleeve 414 is connected to one of the connecting outer tube 413 and the connecting inner tube 412, and can pivot relative to the other of the connecting outer tube 413 and the connecting inner tube 412. In this way, the smoothness of the rotation of the connecting inner tube 412 is improved, and at the same time, the service life of the connecting inner tube 412 and the connecting outer tube 413 is improved. Specifically, in this embodiment, the wear-resistant sleeve 414 is connected to the connecting outer tube 413, and can pivot relative to the connecting inner tube 412. More specifically, the wear-resistant sleeve 414 is provided with an elastic arm 4141, and a limiting structure 4142 is provided on the elastic arm 4141. The connecting outer tube 413 is provided with a bayonet, and the bayonet is used to be engaged with the limiting structure 4142. In one embodiment, the connecting outer tube 413 and the connecting inner tube 412 are made of metal such as steel or aluminum, and the wear-resistant sleeve 414 is made of resin, polyethylene or other materials. The hardness of the wear-resistant sleeve 414 is less than the hardness of the connecting outer tube 413 or the connecting inner tube 412.

[0202] See also Figure 43 to Figure 46In another embodiment, the second locking member 270 may be, for example, a sleeve structure. The second locking member 270 is sleeved outside the connecting inner tube 412 and is slidable relative to the connecting inner tube 412, so that the second locking member 270 has a third position and a fourth position on the connecting inner tube 412. Specifically, a limiting portion 271 is provided on the second locking member 270, and the limiting portion 271 is used to limit the rotation of the second locking member 270 relative to the connecting inner tube 412. The tube wall of the connecting inner tube 412 is provided with a strip hole 4121, and the limiting portion 271 may be, for example, a convex strip formed on or detachably connected to the second locking member 270, and the convex strip passes through the strip hole 4121 to extend into the interior of the connecting inner tube 412. In this way, when one of the connecting inner tube 412 and the second locking member 270 rotates, the other rotates accordingly, and at the same time does not affect the sliding of the second locking member 270 on the connecting inner tube 412. As Fig.45 and Fig.46 As shown, the second locking member 270 is further provided with a locking portion 272, and the connecting outer tube 413 is provided with a second matching portion 4131, which is used to lock and match with the locking portion 272. Specifically, when the second locking member 270 is in the third position (see Fig.45 ), the locking portion 272 is locked with the second matching portion 4131, and the connecting inner tube 412 and the connecting outer tube 413 are relatively fixed. When the second locking member 270 is in the fourth position (see Fig.46 ), the locking portion 272 is separated from the second matching portion 4131, and the connecting inner tube 412 and the connecting outer tube 413 can rotate relative to each other. It should be noted that one of the locking portion 272 and the second matching portion 4131 is a locking convex, and the other is a locking concave, and the locking concave cooperates with the locking convex to achieve relative fixation of the second locking member 270 and the connecting outer tube 413.

[0203] See also Fig.43 and Fig.44 In another embodiment, the base assembly 20 further includes a third release mechanism 370. The third release mechanism 370 is operably connected to the second locking member 270 and is used to drive the second locking member 270 to move from the third position to the fourth position. In this way, the user can directly control the position of the second locking member 270 through the third release mechanism 370. Specifically, Figure 43 to Figure 46As shown, the third release mechanism 370 includes a driving wheel 371, a third operating member 372 and a third traction assembly 373. More specifically, the second locking member 270 is provided with a tooth groove 273, the driving wheel 371 is rotatably disposed in the base assembly 20 and is provided with a meshing tooth 3711, and the driving wheel 371 is engaged with the tooth groove 273 through the meshing tooth 3711 to drive the second locking member 270 to move. The third operating member 372 is slidably disposed on the base assembly 20, and the third traction assembly 373 is connected between the third operating member 372 and the driving wheel 371. When the third operating member 372 is operated, the third operating member 372 can drive the driving wheel 371 to rotate through the third traction assembly 373, so as to drive the second locking member 270 to move from the third position to the fourth position.

[0204] like Figure 43 to Figure 46 As shown, in another embodiment, the third traction assembly 373 includes a third traction rope 3731 and a third traction sleeve 3732 movably sleeved outside the third traction rope 3731. The third traction sleeve 3732 is a bendable wire sleeve and has a first sleeve end 37321 and a second sleeve end 37322. The third traction rope 3731 has a first rope end 37311 adjacent to the first sleeve end 37321 and a second rope end 37312 adjacent to the second sleeve end 37322. The first rope end 37311 of the third traction rope 3731 is connected to the driving wheel 371, and the second rope end 37312 of the third traction rope 3731 is connected to the base assembly 20. The first sleeve end 37321 of the third traction sleeve 3732 is connected to the base assembly 20, and the second sleeve end 37322 of the third traction sleeve 3732 is connected to the third operating member 372. When the third operating member 372 is operated, the third traction sleeve 3732 is deformed so that the third traction rope 3731 pulls the driving wheel 371 to rotate, thereby driving the second locking member 270 to move from the third position to the fourth position.

[0205] It should be noted that the third traction sleeve 3732 and the first traction sleeve 2442 are both bendable wire sleeves.

[0206] See also Figure 43 to Figure 46In another embodiment, the first base 201 is generally in a T-shaped structure, the driving wheel 371 is rotatably disposed in the vertical portion of the T-shaped structure, the connecting outer tube 413 is fixedly disposed in the horizontal portion of the T-shaped structure, and the third operating member 372 moves in the horizontal portion of the T-shaped structure along the left-right direction (the second direction F2). When the second locking member 270 needs to be switched from the third position to the fourth position, the third operating member 372 is pushed toward the inner side of the base assembly 20 along the second direction F2, and the third operating member 372 drives the second sleeve end 37322 to move, and at the same time, the second traction sleeve 3122 is squeezed and bent, so that the third traction rope 3731 is bent along the third traction sleeve 3732. Since the second rope end 37312 of the third traction rope 3731 is fixed, when the third traction rope 3731 is bent, the distance between the first rope end 37311 and the second rope end 37312 is shortened, so that the first rope end 37311 moves toward the first sleeve end 37321 to drive the driving wheel 371 to rotate. In other words, when the third operating member 372 is pushed toward the inner side of the base assembly 20 along the second direction, the third operating member 372 drives the second sleeve end 37322 to move, and the length of the section L3 of the third traction rope 3731 between the second sleeve end 37322 and the second rope end 37312 increases (see FIG. 2 ). Figures 44 to 46 At the same time, under the transmission effect of the third traction sleeve 3732, the length of the section L4 of the third traction rope 3731 between the first rope end 37311 and the first sleeve end 37321 is reduced (see Figures 44 to 46 ), the first rope end 37311 pulls the driving wheel 371 to rotate, so that the second locking member 270 switches from the third position to the fourth position.

[0207] Optionally, in this embodiment, the connecting inner tube 412 may include two detachably connected short sections. Of course, in other embodiments, the connecting inner tube 412 may also be a complete connecting inner tube 412, that is, a long section.

[0208] Continue to see Figure 43 to Figure 46 In another embodiment, two connecting outer tubes 413 are provided, and the two connecting outer tubes 413 are arranged at intervals along the length direction of the connecting inner tube 412. Two second locking members 270 are provided, and the two second locking members 270 are located between the two connecting outer tubes 413 and correspond to the two connecting outer tubes 413 respectively. Two third release mechanisms 370 are provided and are operably connected to the corresponding second locking members 270 respectively. Specifically, the two driving wheels 371 in the two third release mechanisms 370 are meshed. Therefore, when one of the driving wheels 371 rotates, it will drive the other driving wheel 371 to rotate, so that the two second locking members 270 move simultaneously. In this way, the user can manipulate any one of the third operating members 372 to change the positions of the two second locking members 270 at the same time.

[0209] like Figure 43 to Figure 46 As shown, in another embodiment, in order to enable the second locking member 270 to automatically reset, that is, automatically move from the fourth position to the third position, the base assembly 20 further includes an eighth reset member 380. The two second locking members 270 are arranged at intervals, and the eighth reset member 380 abuts between the two second locking members 270 to provide elastic restoring force for the two second locking members 270, so that the two second locking members 270 are both kept in the third position.

[0210] Combine the following Figure 43 to Figure 46 The switching process between the unfolded state and the folded state of the first connecting mechanism 40 provided in another embodiment of the present application is described.

[0211] When the first connecting mechanism 40 is kept in the unfolded state, the second locking member 270 is located in the third position. At this time, the locking portion 272 of the second locking member 270 is engaged with the second matching portion 4131 on the connecting outer tube 413 (see FIG. Fig.43 and Fig.45 ), the connecting inner tube 412 and the connecting outer tube 413 remain relatively fixed.

[0212] When it is necessary to switch the first connection mechanism 40 from the unfolded state to the folded state, the user can directly push any third operating member 372 inward, for example, push the third operating member 372 on the left side inward, and the third operating member 372 moves rightward along the left-right direction (the second direction F2). Under the transmission effect of the third traction rope 3731 and the third traction sleeve 3732, the driving wheel 371 on the left side can be rotated in the counterclockwise direction. Since the driving wheel 371 is engaged with the tooth groove 273 on the second locking member 270, when the driving wheel 371 on the left side rotates in the counterclockwise direction, it will drive the second locking member 270 on the left side to move rightward, so that the locking portion 272 of the second locking member 270 is separated from the second matching portion 4131 on the connecting outer tube 413 (see FIG. 2 ). Fig.46 ). When the locking portion 272 is disengaged from the second matching portion 4131, the rotation of the connecting inner tube 412 is not restricted, and the user can hold the connecting plug 420 to drive the connecting inner tube 412 to rotate around the rotation axis XX. It should be noted that, since the two driving wheels 371 are engaged, when the driving wheel 371 on the left rotates in the counterclockwise direction, the driving wheel 371 on the right will rotate in the clockwise direction, and thus, the second locking member 270 on the right will be driven to move to the left, so that the locking portion 272 of the second locking member 270 is disengaged from the second matching portion 4131 on the corresponding connecting outer tube 413.

[0213] When the first connection mechanism 40 switches to the folded state, the second matching portion 4131 on the connecting outer tube 413 is aligned with the locking portion 272 of the second locking member 270 again. Since the eighth reset member 380 is provided between the two second locking members 270, after the user releases the third operating member 372, the second locking member 270 on the left side moves to the left, and the second locking member 270 on the right side moves to the right, so that the locking portions 272 of the two second locking members 270 will be again engaged with the second matching portions 4131 on the corresponding connecting outer tube 413, so that the rotation of the two second locking members 270 and the connecting inner tube 412 is restricted, thereby keeping the first connection mechanism 40 in the folded state.

[0214] Similarly, when the first connecting mechanism 40 needs to be switched from the folded state to the unfolded state, its working principle is the same as when the first connecting mechanism 40 is switched from the unfolded state to the folded state, and the working process is opposite, which will not be repeated here.

[0215] See also Fig.47 In another embodiment, the second locking member 270 and the third unlocking mechanism 370 can be omitted. In this case, the connecting inner tube 412 can rotate freely relative to the connecting outer tube 413. When the first connecting mechanism 40 can freely switch between the folded state and the unfolded state, after the connecting structure 200 connects the baby safety carrier to the car seat 2000, if the car accelerates suddenly, the baby safety carrier and the base assembly 20 have a tendency to tip backward in the clockwise direction relative to the seat 2000 under the action of inertia. To avoid the above problems, refer to Figures 48 to 51 The connection structure 200 also includes an abutment rod 60, which is used to abut against the backrest of the car seat 2000. Optionally, the abutment rod 60 can be directly set on the base assembly 20 (for example, the first base 201). Alternatively, the abutment rod 60 can pass through the base assembly 20 to be connected to the connecting outer tube 413. Alternatively, the abutment rod 60 can pass through the base assembly 20 and the connecting outer tube 413 to be connected to the connecting inner tube. Since the angle between the abutment rod 60 and the base assembly 20 remains fixed, when the abutment rod 60 abuts against the backrest, the base assembly 20 cannot flip backward relative to the car seat 2000, so that the stability of the baby safety basket after installation can be improved.

[0216] It should be noted that the abutment rod 60 can be fixedly mounted on the base assembly 20 or the connecting outer tube 413 or the connecting inner tube 412. Of course, the abutment rod 60 can be pivotally connected to the base assembly 20 or the connecting outer tube 413 or the connecting inner tube 412. When the abutment rod 60 can be pivotally connected relative to the base assembly 20 or the connecting outer tube 413 or the connecting inner tube 412, the base assembly 20 also has another locking mechanism for locking the abutment rod 60. Of course, the abutment rod 60 can also be connected to the base assembly 20 or the connecting outer tube 413 or the connecting inner tube 412 in a detachable manner.

[0217] Of course, if Fig.49 As shown, in another embodiment in which the base assembly 20 has a second locking member 270 and a third unlocking mechanism 370, the connecting structure 200 may still include the above-mentioned abutting rod 60, which is equivalent to the above-mentioned abutting rod 60 still being provided on the base assembly 20. Compared with the case where the abutting rod 60 is not provided, the abutting rod 60 is provided to indirectly increase the abutting area between the baby safety basket and the backrest, so that the stability of the baby safety basket after installation can be further improved. It should be noted that when the connecting structure 200 includes the abutting rod 60, that is, when the base assembly 20 is provided with the abutting rod 60, the abutting member 106 at the front end of the baby carrier body 100 can be omitted.

[0218] See also Fig.52 In some embodiments in which the abutment rod 60 is provided, the connection structure 200 further includes a safety tether 70. The safety tether 70 includes a fixing portion 710 and a connecting portion 720. The fixing portion 710 is connected to the abutment rod 60, and the connecting portion 720 is used to connect to the anchor point of the car seat 2000. In this way, the stability of the connection structure 200 and the baby safety carrier fixed on the car seat 2000 can be ensured to avoid sliding forward and backward and / or left and right. Specifically, the fixing portion 710 and / or the connecting portion 720 are provided with a connecting member 730, such as a hook, a ring and other components, so that the convenience and stability of the connection can be improved. More specifically, the safety tether 70 is provided with an adjuster 80, which is used to adjust the available length of the safety tether 70.

[0219] See also Fig.53 and Fig.54, a through portion 601 is provided on the abutting rod 60. After the safety strap 70 passes through the through portion 601, its fixing portion 710 is used to connect to the connecting buckle 107 of the infant safety basket, and the connecting portion 720 is still used to connect to the anchor point of the car seat 2000. Specifically, in the present embodiment, the safety strap 70 is in a Y-shaped structure, that is, the safety strap has two branches extending outward from one end of the connecting portion 720, thereby forming two fixing portions 710. The two fixing portions 710 drive the two branches to surround the infant safety basket, which is equivalent to being connected to the connecting buckle 107 on the back of the infant safety basket in a "hugging" manner. As shown Figure 4 and Figure 6 As shown, in one embodiment, the first base 201 is generally T-shaped, the second base 202 is generally rectangular, and the width of the second base 202 along the left-right direction can be regarded as the width W1 of the second connecting mechanism 50. Fig.38 and Fig.39 As shown, in another embodiment, the second base 202 may also be generally T-shaped. Specifically, the vertical portion of the T-shaped structure of the first base 201 is connected to the vertical portion of the T-shaped structure of the second base 202, so that a slot 205 with one end open can be formed on both sides of the base assembly 20. Fig.46 Since the plug connection assembly 410 is arranged at the horizontal part of the T-shaped structure of the first base 201 (the connecting outer tube 413 is fixedly installed at the horizontal part of the first base 201, and the connecting inner tube 412 is rotatably installed at the horizontal part of the first base 201), the end of the connecting inner tube 412 is connected to the connecting plug 420. Therefore, when the connecting inner tube 412 rotates to put the first connecting mechanism 40 in the folded state, at least part of the connecting plug 420 is blocked at the opening of the empty slot 205 (see Fig.39 ), so that the user can easily put his hand into the empty slot 205 to hold the horizontal part of the T-shaped structure of the first base 201 or the connecting plug 420, thereby improving the portability of the connecting structure 200.

[0220] See also Figure 55 to Figure 58 In another embodiment, the bottom surface of the second base 202 is inclined relative to the bottom surface of the first base 201, that is, the first lower shell 201B and the second lower shell 202B are arranged at an angle, so that when the baby safety basket is engaged with the second connecting mechanism 50, the bottom surface of the first base 201 does not contact the car seat 2000. Fig.36 and Fig.37As shown, when the base assembly 20 is connected to the car seat 2000 through the first connection mechanism 40 (i.e., the connection plug 420), the opening of the angle α2 between the first lower shell 201B and the second lower shell 202B faces the seat portion of the car seat 2000, and the first lower shell 201B and part of the shell of the second lower shell 202B (i.e., except for the shell of the end of the second lower shell 202B away from the first lower shell 201B) are suspended and do not contact the seat portion. In this way, a movable space can be provided for the connection plug 420 and the base assembly 20 to bend relative to each other.

[0221] See also Figure 3 and Figure 5 Or see Fig.33 and Fig.34 In some of the above embodiments, the bottom of the mounting rib 104 of the baby carrier body 100 is an arc-shaped structure. In this way, when the baby safety basket is placed on a horizontal surface, the user can shake the baby safety basket by pressing the end of the baby safety basket up and down to comfort the infant lying in the baby safety basket. Specifically, the front engaging member 101 can be arranged in the area between the front end of the arc structure and the middle part along the circumferential direction of the arc structure. When the front engaging member 101 is connected to the second connecting mechanism 50, the base assembly 20 (accommodating groove 204) can support the front end area of ​​the arc mechanism. In this way, when the baby safety basket is connected to the car seat 2000 through the connecting structure 200, the supporting area of ​​the seat part of the car seat 2000 to the mounting rib 104 (the bottom of the baby safety basket) is indirectly increased, so that the baby safety basket is not prone to shaking back and forth after installation.

[0222] At present, the seat portion of the automobile seat 2000 can be roughly divided into two situations. One is that the seat portion is parallel to the horizontal plane, that is, the seat surface is parallel to the horizontal plane (see Fig.36 or Fig.50 ); the second is that the seat portion is inclined relative to the horizontal plane, that is, the seat surface is inclined to the horizontal plane (see Fig.37 or Fig.51 ). Since the connecting plug 420 can rotate with the connecting inner tube 412, when the car seat 2000 has different seat surfaces, the angle α3 between the connecting plug 420 and the base assembly 20 can be changed by rotating the base assembly 20 or the connecting plug 420, so that the baby safety carrier can adapt to different car seats 2000. Specifically, Fig.36 As shown, when the seat surface is horizontal, the baby safety carrier is fixed to the car seat 2000 through the connecting structure 200. At this time, the angle α3 between the connecting plug 420 and the base assembly 20 is approximately 180°, and there is no need to bend between the two. Fig.37As shown, when the seat surface is in an inclined state, in order to ensure that the baby safety basket can be directly supported on the seat surface, the base assembly 20 needs to be bent so that the angle α3 between the connecting plug 420 and the base assembly 20 is approximately an obtuse angle. Further, the angle α3 between the connecting plug 420 and the first base 201 can be adaptively adjusted according to the different inclination angles of the seat surface, so that the adaptability of the connecting structure 200 to different car seats 2000 can be improved. In addition, the method of rotating the connecting inner tube 412 to change the angle α3 between the connecting plug 420 and the base assembly 20 can also be used to adjust the inclination angle of the baby safety basket relative to the seat surface, so that the pitch angle of the baby safety basket relative to the car seat 2000 can be adjusted, and then the state (sitting or lying position) of the infant in the baby safety basket relative to the car seat 2000 can be changed.

[0223] The connection plug 420 is, for example, an ISOFIX plug or other suitable plug. Fig.26 and Fig. 27 As shown, in one embodiment, the connecting plug 420 is an ISOFIX plug. The connecting plug 420 may include a shell 421, a locking hook 422, and a locking member 423. A cavity 4211 is formed in the shell 421, and the end of the shell 421 away from the plug connecting assembly 410 has a locking groove 4212, and the locking groove 4212 is used to accommodate a locking rod on the car seat 2000 (not shown in the figure). The groove wall of the locking groove 4212 is provided with a through hole, and the through hole connects the locking groove 4212 and the cavity 4211. The locking hook 422 is located in the cavity 4211 and is pivotally connected to the shell 421, so that the locking hook 422 has a locking position and an unlocking position. Specifically, when the locking hook 422 is in the locking position (see Fig.26 ), the locking hook 422 at least partially blocks the notch of the locking groove 4212 to lock the clamping rod and achieve the connection between the first connecting mechanism 40 and the car seat 2000. When the locking hook 422 is in the unlocking position (see Fig. 27), the notch of the locking groove 4212 is open, and the latch rod can be separated from the lock hook 422. More specifically, the locking member 423 is located in the cavity 4211 and can slide relative to the lock hook 422 to approach the lock hook 422 or move away from the lock hook 422. One of the lock hook 422 and the locking member 423 facing the side of the lock hook 422 is provided with a latch groove 4221, and the other is provided with a latch block 4231. When the lock hook 422 is in the latching position, the latch block 4231 is latched in the latch groove 4221 to keep the lock hook 422 in the latching position. When the latch block 4231 withdraws from the latch groove 4221, the lock hook 422 can pivot so that the lock hook 422 can switch to the unlocking position. Further, a seventh reset member (not shown in the drawings) is provided in the cavity 4211, and the seventh reset member is, for example, a torsion spring. The seventh reset member abuts against the lock hook 422 and is suitable for biasing the lock hook 422 to rotate toward the unlocking position. Therefore, when the locking block 4231 withdraws from the locking slot 4221, the lock hook 422 automatically switches to the unlocking position under the action of the seventh reset member, thereby facilitating and smoothly unlocking, and the problem of the lock hook 422 being locked is not likely to occur.

[0224] See also Fig.28 and Fig.29 In one embodiment, the second connection mechanism 50 includes a locking hook 510 and a limiting groove 520 provided on the base assembly 20. The limiting groove 520 is used to accommodate the front locking member 101 of the infant carrier body 100. The locking hook 510 is pivotally connected to the base assembly 20 and has a locking position and a release position. When the locking hook 510 is in the locking position, the locking hook 510 at least partially extends into the notch of the limiting groove 520 (see FIG. Fig.28 ) to lock and limit the front engaging member 101. When the engaging hook 510 is in the unlocking position, the notch of the limiting groove 520 is open (see Fig.29 ), the front engaging member 101 can be disengaged from the engaging hook 510. When the front engaging member 101 is engaged in the limiting groove 520, the edges on both sides of the top of the limiting groove 520, that is, the upper surface of the base assembly 20, abut against the lower surface of the baby carrier body 100 to prevent the baby carrier body 100 from pivoting relative to the base assembly 20.

[0225] See also Fig.28 and Fig.29 In one embodiment, the groove wall of the limiting groove 520 is provided with a through hole (not shown in the figure), and the through hole connects the accommodating cavity 203 and the limiting groove 520. Specifically, the engaging hook 510 is provided with an accommodating groove 511 adapted to the front engaging member 101, and the accommodating groove 511 is U-shaped and the opposite two side walls respectively form a locking wall surface 5111 and a pushing wall surface 5112 (see Fig.30). The pushing wall surface 5112 is adapted to be pushed by the front engaging member 101 to drive the engaging hook 510 to pivot from the unlocking position to the locking position. A portion of the engaging hook 510 is accommodated in the accommodating cavity 203 and is pivotally connected to the side wall of the accommodating cavity 203 via the pivot axis 530. Specifically, in this embodiment, the engaging hook 510 is pivotally connected to the sliding frame 220 via the pivot axis (see Figure 8 and Fig. 9 ), and the sliding frame 220 is provided with a snap-fitting groove 224 (see Fig.12 and Fig.13 ), the limiting groove 520 forms a locking portion 2023 on the side wall of the accommodating cavity 203 (see Fig.10 and Fig.29 ), the shape of the engaging groove 224 is adapted to the engaging portion 2023, so that the engaging portion 2023 engages with the engaging groove 224. More specifically, when the engaging hook 510 is in the locking position, the locking wall surface 5111 is located in the limiting groove 520 and blocks the notch of the limiting groove 520. When the engaging hook 510 is in the unlocking position, the pushing wall surface 5112 is located in the limiting groove 520, and the locking wall surface 5111 is located in the accommodating cavity 203.

[0226] In one embodiment, if Fig.28 As shown, when the locking hook 510 is in the locked position, the front locking member 101 abuts against the pushing wall 5112, and a gap is formed between the locking wall 5111 and the front locking member 101. In this way, when the locking hook 510 pivots around the pivot shaft 530 to switch the locking hook 510 to the unlocking position, it is convenient for the front locking member 101 to be disengaged from the locking hook 510.

[0227] In one embodiment, the base assembly 20 further includes a locking and retaining mechanism 290. Figure 8 , Fig. 9 as well as Fig.28 , Fig.29 As shown, the locking and holding mechanism 290 is movably disposed in the accommodating cavity 203. When the locking hook 510 is driven to the locking position, the locking and holding mechanism 290 is used to lock the locking hook 510 in the locking position.

[0228] See also Figure 8 and Fig. 9In one embodiment, the locking and holding mechanism 290 may include a stopper 291, which is movably disposed in the accommodating cavity 203 and has a fifth position and a sixth position. Specifically, the stopper 291 is pivotally connected to the bottom wall of the base assembly 20 around the first pivot point Q1. One of the stopper 291 and the engaging hook 510 is provided with a locking recess 513, and the other is provided with a first matching portion 2911. In other words, when the stopper 291 is provided with a locking recess 513, the engaging hook 510 is provided with a first matching portion 2911; or, when the engaging hook 510 is provided with a locking recess 513, the stopper 291 is provided with a first matching portion 2911. Specifically, in this embodiment, the engaging hook 510 is provided with a locking recess 513, and the locking recess 513 is a locking notch, and the stopper 291 has a first matching portion 2911, and the first matching portion 2911 is a convex portion. More specifically, when the stopper 291 is in the fifth position, the locking recess 513 and the first matching portion 2911 are matched to lock the hook 510 in the locking position. When the stopper 291 is in the sixth position, the locking recess 513 is separated from the first matching portion 2911 and the hook 510 is in the unlocking position.

[0229] Continue to see Figure 8 and Fig. 9 In one embodiment, the locking and holding mechanism 290 further includes a fifth reset member 292. The fifth reset member 292 provides elastic restoring force for the limiting member 291 to drive the limiting member 291 to switch to the fifth position. The fifth reset member 292 is, for example, a spring. Thus, when the locking hook 510 pivots from the unlocking position to the locking position, the limiting member 291 can be automatically switched to the fifth position under the action of the fifth reset member 292, so that the first matching portion 2911 of the limiting member 291 extends into the locking recess 513 of the locking hook 510 to lock the locking hook 510, and the locking hook 510 is kept in the locked position.

[0230] Further, see Figures 8 to 10 In one embodiment, the second connection mechanism 50 further includes a sixth reset member 330, which abuts against the locking hook 510 to keep the locking hook 510 in the unlocked position. The sixth reset member 330 is, for example, a torsion spring, which is sleeved on the pivot shaft 530 and abuts against the locking hook 510. Thus, when the first matching portion 2911 is withdrawn from the locking recess 513, the locking hook 510 can automatically rotate around the pivot shaft 530 to be in the unlocked position, thereby facilitating and smoothly unlocking, and the locking hook 510 is not likely to be locked.

[0231] Combine the following Figure 8 , Fig. 9 , Fig.28 as well as Fig.29 The locking and releasing principles of the locking hook 510 provided according to an embodiment of the present application are described below.

[0232] See also Fig. 9 and Fig.29 When the infant carrier body 100 is not mounted on the base assembly 20 , the engaging hook 510 is kept in the unlocking position under the action of the sixth restoring member 330 . Meanwhile, the limiting member 291 is in the sixth position, and the first matching portion 2911 is separated from the locking recess 513 .

[0233] Continue to see Fig. 9 and Fig.29 When the baby carrier body 100 needs to be installed on the base assembly 20, that is, when the front engaging member 101 needs to be connected to the second connecting mechanism 50, the user can first put the front engaging member 101 into the limiting groove 520 and make the front engaging member 101 abut against the pushing wall 5112. Then, the front engaging member 101 is pushed downward to drive the engaging hook 510 to rotate clockwise around the pivot shaft 530 until the pushing wall 5112 withdraws from the limiting groove 520, and the locking wall 5111 extends into the limiting groove 520 to block the notch of the limiting groove 520. At the same time, the engaging hook 510 rotates so that the locking recess 513 is opposite to the first matching portion 2911, and the fifth restoring member 292 drives the first matching portion 2911 to move and extend into the locking recess 513, and finally the engaging hook 510 is kept in the locked position to achieve a stable connection with the front engaging member 101.

[0234] See also Figure 8 and Fig.28 When the baby carrier body 100 needs to be separated from the base assembly 20, that is, when the front engaging member 101 needs to be separated from the second connecting mechanism 50, the user can move the limiting member 291 from the fifth position to the sixth position, during which the first matching portion 2911 gradually withdraws from the locking recess 513. When the first matching portion 2911 completely withdraws from the locking recess 513, the engaging hook 510 automatically rotates counterclockwise around the pivot shaft 530 under the action of the sixth restoring member 330, and the locking wall surface 5111 withdraws from the limiting groove 520, so that the notch of the limiting groove 520 is opened.

[0235] In one embodiment, if Fig.29 and Fig.30As shown, a push convex point 512 is provided in the receiving groove 511, and the push convex point 512 is arranged on the push wall surface 5112 and is located on the moving path of the front engaging member 101 on the push wall surface 5112. The push convex point 512 is suitable for being pushed by the front engaging member 101 so that the engaging hook 510 can pivot to the locking position. Specifically, when the engaging hook 510 needs to switch from the unlocking position to the locking position, the user can push the pushing wall surface 5112 downward through the front engaging member 101. During the downward pressing process, the engaging hook 510 pivots, and the front engaging member 101 gradually moves on the push wall surface 5112 toward the bottom of the U-shaped receiving groove 511, and at the same time, the locking recess 513 on the engaging hook 510 gradually approaches the first matching portion 2911 of the limiting member 291. Since the push protrusion 512 is arranged on the moving path of the front engaging member 101 on the push wall 5112 and protrudes from the push wall 5112, when the front engaging member 101 crosses the push protrusion 512, it can drive the engaging hook 510 to further pivot, so that when the front engaging member 101 moves to the bottom of the accommodating groove 511, the first matching portion 2911 can be fully inserted into the locking recess 513. The width of the locking recess 513 is greater than the thickness of the first matching portion 2911. When the front engaging member 101 is at the top of the push convex point 512, the middle of the locking recess 513 is opposite to the first matching portion 2911, so that the first matching portion 2911 can be inserted into the bottom of the locking recess 513 without contacting the side wall of the locking recess 513; when the front engaging member 101 crosses the top of the push convex point 512 and reaches the engaging position, the locking recess 513 pivots relative to the first matching portion 2911, and a side wall of the locking recess 513 abuts against the first matching portion 2911, so that the locking recess 513 is tightly engaged with the first matching portion 2911. More specifically, when the engaging hook 510 is in the locking position, the push convex point 512 is interference-fitted with the front engaging member 101.

[0236] In order to facilitate the user to manipulate the limiting member 291 to place the locking hook 510 in the unlocking position, in one embodiment, Figure 8 and Fig. 9 As shown, the base assembly 20 further includes a second release mechanism 310. The second release mechanism 310 is operably connected to the limit member 291 and is used to drive the limit member 291 to move from the fifth position to the sixth position. In this way, the user can switch the limit member 291 from the fifth position to the sixth position by manipulating the second release mechanism 310.

[0237] See also Figure 8 and Fig. 9In one embodiment, the second unlocking mechanism 310 includes a second operating member 311 and a second pulling assembly 312. The second operating member 311 is slidably disposed on the base assembly 20 and has a seventh position and an eighth position. The second pulling assembly 312 is connected between the second operating member 311 and the limiting member 291. When the second operating member 311 is in the seventh position, the limiting member 291 is in the fifth position. At this time, the first matching portion 2911 of the limiting member 291 extends into the locking recess of the locking hook 510 to keep the locking hook 510 in the locked position. When the second operating member 311 is in the eighth position, the limiting member 291 is in the sixth position. At this time, the first matching portion 2911 of the limiting member 291 is disengaged from the locking recess of the locking hook 510, so that the locking hook 510 can be switched to the unlocking position.

[0238] Continue to see Figure 8 and Fig. 9 Specifically, in this embodiment, the second traction assembly 312 includes a second traction rope 3121 and a second traction sleeve 3122 movably mounted outside the second traction rope 3121. The second traction sleeve 3122 has a first sleeve end 31221 and a second sleeve end 31222 (see Figure 6 ), the second traction rope 3121 has a first rope end 31211 adjacent to the first sleeve end 31221 and a second rope end (not shown) adjacent to the second sleeve end 31222. More specifically, the first rope end 31211 of the second traction rope 3121 is connected to the stopper 291, and the second rope end of the second traction rope 3121 is connected to the base assembly 20. The first sleeve end 31221 of the second traction sleeve 3122 is connected to the base assembly 20, and the second sleeve end 31222 of the second traction sleeve 3122 is connected to the second operating member 311. Specifically, the second operating member 311 is provided with a second fixing portion 3113 (see Fig.23 and Fig.31 ), the second fixing portion 3113 is used to connect the second sleeve end 31222 of the second traction sleeve 3122. When the second operating member 311 is switched from the seventh position to the eighth position, the second traction sleeve 3122 is deformed so that the second traction rope 3121 pulls the limiting member 291 to switch from the fifth position to the sixth position.

[0239] It should be noted that the second traction sleeve 3122 and the first traction sleeve 2442 are both bendable wire sleeves.

[0240] See also Figure 8 , Fig. 9 and Fig.23In this embodiment, the base assembly 20 is generally T-shaped, the stopper 291 slides in the vertical portion of the T-shaped base assembly 20, and the second operating member 311 moves on the horizontal portion of the T-shaped base assembly 20. Correspondingly, the second traction rope 3121 and the second traction sleeve 3122 are bent in the base assembly 20 so that the first rope end 31211 is connected to the stopper 291, the first sleeve end 31221 is connected to the vertical portion of the base assembly 20; the second rope end is connected to the horizontal portion of the base assembly 20, and the second sleeve end 31222 is connected to the second operating member 311. More specifically, the second operating member 311 moves in the horizontal portion of the T-shaped base assembly 20 along the left-right direction (the second direction F2). When it is necessary to switch the limiting member 291 from the fifth position to the sixth position, the second operating member 311 is pushed toward the inner side of the base assembly 20 along the second direction F2, and the second operating member 311 drives the second sleeve end 31222 to move, and at the same time, the second traction sleeve 3122 is squeezed and bent, so that the second traction rope 3121 bends along the second traction sleeve 3122. Since the second rope end of the second traction rope 3121 is fixed, when the second traction rope 3121 bends, the distance between the first rope end 31211 and the second rope end is shortened, so that the first rope end 31211 moves toward the first sleeve end 31221 (that is, the first rope end 31211 moves forward along the front-to-back direction). In other words, when the second operating member 311 is pushed toward the inner side of the base assembly 20 along the second direction F2, the second operating member 311 drives the second sleeve end 31222 to move, and the length of the section L2 of the second traction rope 3121 between the second sleeve end 31222 and the second rope end increases (see Fig.23 At the same time, under the transmission effect of the second traction sleeve 3122, the length of the section L1 of the second traction rope 3121 between the first rope end 31211 and the first sleeve end 31221 is reduced (see Figure 8 and Fig. 9 ), the first rope end 31211 pulls the limiting member 291 to pivot, so that the limiting member 291 switches from the fifth position to the sixth position.

[0241] See also Figure 5 , usually when the baby carrier body 100 is connected to the base assembly 20 through the second connection mechanism 50, the gap between the baby carrier body 100 and the base assembly 20 is small. In this embodiment, the convenience of unlocking can be improved by pushing the second operating member 311 inward. In other words, the problem of inconvenience in unlocking due to the small gap between the baby carrier body 100 and the base assembly 20 after the two are installed can be solved by pushing the second operating member 311 inward. Specifically, in this embodiment, as shown in FIG. Figure 5 , Fig. 22 as well as Fig.31The second operating member 311 has a push portion 3112. The push portion 3112 is convexly disposed on the sliding plane of the second operating member 311 on the base assembly 20. When operating the second operating member 311, the push portion 3112 can be pushed by a finger.

[0242] Of course, in other embodiments, the second traction assembly 312 may only include the second traction rope 3121. The first rope end 31211 of the second traction rope 3121 is connected to the stopper 291, and the second rope end of the second traction rope 3121 is connected to the second operating member 311. At this time, when the stopper 291 needs to be switched from the fifth position to the sixth position, the second operating member 311 can be pulled toward the outside of the base assembly 20 along the second direction F2, driving the stopper 291 to rotate so that the first matching portion 2911 is withdrawn from the locking recess 513.

[0243] See also Figure 6 , Figure 8 as well as Fig.23 In one embodiment, the second release mechanism 310 further includes a fourth restoring member 320. The fourth restoring member 320 provides elastic restoring force for the second operating member 311, so that the second operating member 311 is maintained at the seventh position.

[0244] In one embodiment, if Figure 6 As shown in FIG. 1 , the base assembly 20 has a release indication area 340. The release indication area 340 indicates that the first locking member 230 is in a locked position or a release position according to the relative position between the second operating member 311 and the base assembly 200. The release indication area 340 is, for example, two color blocks (for example, one is green and the other is red) located on the base assembly 20. The second operating member 311 is provided with an observation hole 3111 (see FIG. 1 ) for observing the release indication area 340. Figure 7 , Fig.32 ). When the second operating member 311 slides on the base assembly 20, the viewing hole 3111 can switch between the two color blocks, so the user can judge whether the first locking member 230 is in the locked position or the unlocked position by the color displayed in the viewing hole 3111. More specifically, in this embodiment, when the first locking member 230 is in the locked position, the color block displayed in the viewing hole 3111 is green; when the first locking member 230 is in the unlocked position, the color block displayed in the viewing hole 3111 is red. More specifically, the red color block is closer to the outside of the base assembly 20 than the green color block.

[0245] See also Figure 8 and Fig. 9In one embodiment, the second connecting mechanism 50 includes two engaging hooks 510, and the two engaging hooks 510 are spaced apart along the extending direction of the limiting groove 520. Specifically, the limiting groove 520 extends along the first direction F1. The locking and holding mechanism 290 includes two limiting members 291 corresponding to the two engaging hooks 510 respectively. Each limiting member 291 is pivoted to the base assembly 20, and the two limiting members 291 are pivotally connected to each other. Specifically, the two limiting members 291 are pivoted around the second pivot point Q2. Correspondingly, the base assembly 20 is provided with two second operating members 311 and two second traction assemblies 312. Among them, the two second operating members 311 are respectively slidably arranged at the two ends of the horizontal part of the T-shaped base assembly 20, and the second traction assembly 312 is connected between the corresponding second operating member 311 and the corresponding limiting member 291. Therefore, when one of the limit members 291 switches between the fifth position and the sixth position, the other limit member 291 will switch between the fifth position and the sixth position synchronously; in other words, when one of the limit members 291 switches from the fifth position to the sixth position, the other limit member 291 will switch from the fifth position to the sixth position synchronously.

[0246] See also Figure 55 to Figure 59 , another embodiment of the present application provides a second connecting mechanism 50. The second connecting mechanism 50 includes a snap hook 510 and a limiting groove 520 provided on the base assembly 20. Specifically, the structure and setting position of the limiting groove 520 in this embodiment are the same as those in the above-mentioned embodiment, and the setting position of the snap hook 510 in this embodiment is the same as that in the above-mentioned embodiment, and the only difference is that the structure of the snap hook 510 is slightly different. In the absence of conflict, the structure of the snap hook 510 in this embodiment and its connection relationship with other components can be referred to the embodiment shown above, and will not be repeated here. The following mainly describes the differences between this embodiment and the above-mentioned embodiment (i.e., the relevant embodiment of the second connecting mechanism 50).

[0247] See also Fig.55 and Fig.56 In another embodiment, the locking hook 510 is provided with a locking protrusion 514, and the locking recess 513 in the above embodiment is omitted. Correspondingly, in this embodiment, another locking and holding mechanism 290 is provided in the base assembly 20, and the locking and holding mechanism 290 is movably disposed in the accommodating cavity 203 and is used to cooperate with the locking recess 513 to keep the locking hook 510 in the locked position.

[0248] See also Fig.57The locking and holding mechanism 290 includes a locking hook 293 and a ninth reset member 294. The locking hook 293 is provided with a hook portion 2931, and the locking hook 293 is rotatably disposed in the accommodating chamber 203, so that the locking hook 293 has a ninth position and a tenth position. Specifically, when the locking hook 293 is in the ninth position and the engaging hook 510 is in the locking position, the hook portion 2931 is located on the rotation path of the engaging hook 510 and is limitedly engaged with the locking protrusion 514. When the locking hook 293 is in the tenth position, the hook portion 2931 deviates from the rotation path of the engaging hook 510 to allow the engaging hook 510 to rotate. Specifically, the ninth reset member 294 is mainly used to provide an elastic restoring force for the locking hook 293, so that the locking hook 293 is maintained at the ninth position. More specifically, the ninth reset member 294 is located at one end of the locking hook 293 away from the hook portion 2931. Optionally, the ninth reset member 294 can be a tension spring or a compression spring.

[0249] See also Fig.55 and Fig.56 In another embodiment, the cavity wall (second lower shell 202B) of the accommodating cavity 203 is provided with an escape groove 2022, and the escape groove 2022 is located on the rotation path of the hook portion 2931. The escape groove 2022 can increase the rotation stroke of the locking hook 293 to ensure that the locking hook 293 can enter the escape groove 2022 during the rotation process so that the hook portion 2931 is completely separated from the locking protrusion 514, thereby releasing the restriction on the locking hook 510. Of course, in other embodiments, the escape groove 2022 can be omitted.

[0250] Continue to see Fig.55 and Fig.56 , the bottom of the locking protrusion 514 is provided with a push-up inclined surface 5141. The push-up inclined surface 5141 is adapted to push against the hook portion 2931 so that the engaging hook 510 can pivot to the locking position. Specifically, after the user puts the front engaging member 101 into the limiting groove 520, the user pushes downward against the push-up wall surface 5112 of the engaging hook 510. During the downward pressing process, the engaging hook 510 pivots so that the vertex B1 of the locking protrusion 514 turns to abut against the hook portion 2931 of the locking hook 293. When the vertex B1 crosses the hook portion 2931, the hook portion 2931 directly contacts the push-up inclined surface 5141. During this process, since the ninth reset member 294 continues to provide restoring force for the locking hook 293, the hook portion 2931 of the locking hook 293 has a tendency to move generally upward. Therefore, after the hook portion 2931 contacts the push ramp 5141, the hook portion 2931 can move upward along the push ramp 5141 and push the push ramp 5141 to make the engaging hook 510 continue to pivot, so that the locking wall 5111 of the engaging hook 510 is fully extended into the limiting groove 520.

[0251] like Fig.57 and Fig.58As shown, in another embodiment, in order to facilitate the user to operate the locking hook 293, the locking and holding mechanism 290 also includes an operating rod 295 and an operating handle 296. The operating rod 295 is installed in the accommodating cavity 203 and is connected to the locking hook 293. The end of the operating rod 295 passes through the base assembly 20 (for example, the second base 202) and is connected to the operating handle 296. The operating handle 296 can be operated to drive the locking hook 293 to switch from the ninth position to the tenth position. Specifically, the locking hook 293 is fixedly arranged on the operating rod 295, so that when the operating handle 296 is rotated, the operating rod 295 can be rotated therewith, thereby enabling the locking hook 293 to rotate so as to switch between the ninth position and the tenth position. More specifically, as Figure 55 to Figure 59 As shown, the user can rotate the operating handle 296 in the clockwise direction, so that the operating rod 295 will drive the locking hook 293 to rotate in the clockwise direction, so that the hook portion 2931 can move generally downward, thereby retreating from the pivot path of the engaging hook 510 (for example, the locking protrusion 514). In this embodiment, the operating handle 296 is fixedly connected to the operating rod 295. For example, the operating handle 296 is engaged with the operating rod 295; or, the operating handle 296 can also be fixedly connected to the operating rod 295 by a connecting member 730 such as a screw. Specifically, as Fig.54 As shown, an arc groove 2961 is provided on the side of the operating handle 296 facing the base assembly 20, and a clamping portion 2951 is provided at the end of the operating rod 295. The clamping portion 2951 is arranged at an angle with the main body of the operating rod 295, and the clamping portion 2951 is used to be inserted into the arc groove 2961 so that the operating rod 295 can rotate together with the operating handle 296.

[0252] like Fig.57 and Fig.58 As shown, the second connection mechanism 50 includes two snap hooks 510, and the two snap hooks 510 are arranged at intervals along the extension direction of the limiting groove 520. Correspondingly, the locking and holding mechanism 290 includes two locking hooks 293 corresponding to the two snap hooks 510, and the two locking hooks 293 are both arranged on the operating rod 295. The two ends of the operating rod 295 are respectively connected to the operating handles 296. In this way, when one of the operating handles 296 is rotated, under the linkage action of the operating rod 295, the two locking hooks 293 can be controlled to rotate simultaneously, so that the two snap hooks 510 are unlocked at the same time.

[0253] In the connection structure and the baby carrier having the connection structure according to the embodiment of the present application, since the first connection mechanism can be detachably connected to the car seat, and the second connection mechanism can be detachably connected to the front engaging member on the baby carrier body, when the baby carrier body needs to be installed on the car seat, the baby carrier body can be directly connected to the base assembly through the second connection mechanism, and then the base assembly can be connected to the car seat through the first connection mechanism; or, the base assembly can be first connected to the car seat through the first connection mechanism, and then the baby carrier body can be connected to the base assembly through the second connection mechanism to achieve the connection between the baby carrier body and the car seat. In addition, when the baby carrier body needs to be carried alone, the baby carrier body can be directly separated from the base assembly without carrying the entire connection structure, which can effectively reduce the burden of the user when carrying the baby carrier body.

[0254] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0255] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
