Description

Technical Field

[0001] This utility model relates to the field of infant and toddler products technology, and in particular to a connecting structure and an infant carrier. Background Technology

[0002] A car child safety seat, also known as a Child Restraint System (CRS), is a seat designed specifically for children of different ages (or weights) and installed in a car to effectively improve children's safety while traveling. Generally, the appropriate safety seat style needs to be selected based on the child's age or size. For infants aged zero to one year (approximately under ten kilograms), a reclining safety seat, also known as an infant car seat, is generally suitable, allowing the young infant to receive ideal protection within a suitable, dedicated seat.

[0003] Currently, common infant car seats generally consist of a car seat and a base assembly, with the base assembly formed at the bottom of the car seat. When infants need to travel by car, the infant car seat is placed directly on the car seat and connected to the car seat via the base assembly. However, due to structural limitations, these infant car seats are relatively heavy and not lightweight enough. When users carry these infant car seats, it can easily cause fatigue and increase the burden of walking. Utility Model Content

A pushing protrusion is provided within the receiving groove, and the pushing protrusion is located on the pushing wall surface and on the movement path of the front engaging member on the pushing wall surface.

[0083] In one embodiment, the base assembly further includes a second release mechanism operably connected to the limiting member for driving the limiting member to move from the fifth position to the sixth position.

[0084] In one embodiment, the second release mechanism includes: a second operating member slidably disposed on the base assembly and having a seventh position and an eighth position; and a second traction assembly connected between the second operating member and the limiting member. When the second operating member is in the seventh position, the limiting member is in the fifth position; when the second operating member is in the eighth position, the limiting member is in the sixth position. The second traction assembly includes a second traction rope and a second traction sleeve movably sleeved outside the second traction rope. The second traction sleeve has a first sleeve end and a second sleeve end, and the second traction rope has a first rope end adjacent to the first sleeve end and a second rope end adjacent to the second sleeve end. The first rope end of the second traction rope is connected to the limiting member, and the second rope end of the second traction rope is connected to the base assembly; the first sleeve end of the second traction sleeve is connected to the base assembly, and the second sleeve end of the second traction sleeve is connected to the second operating member. When the second operating member switches from the seventh position to the eighth position, the second traction sleeve deforms to cause the second traction rope to pull the limiting member to switch from the fifth position to the sixth position. The release mechanism also includes a fourth reset member, which provides an elastic restoring force to the second operating member so that the second operating member remains in the seventh position.

[0085] In one embodiment, the base assembly has a release indicator area that indicates whether the first locking member is in the locked position or the released position based on the relative position of the second operating member and the base assembly.

[0086] In one embodiment, the second connecting mechanism includes two engaging hooks spaced apart along the extending direction of the limiting groove. The locking and retaining mechanism includes two limiting members corresponding to the two engaging hooks, each limiting member being pivotally connected to the base assembly, and the two limiting members being movably connected to each other.

[0087] In one embodiment, the unlocking mechanism includes a second operating member slidably disposed at the connecting outer tube, the second operating member being positioned laterally outside the second base. The second operating member has a seventh position and an eighth position arranged along the length of the connecting outer tube. When the second operating member is in the seventh position, the first base and the second base are locked in relative sliding; when the second operating member is in the eighth position, the first base and the second base are unlocked.

[0088] According to another aspect of the present invention, an infant carrier is also provided, comprising: an infant carrier body and a connecting structure as described in any of the above embodiments, wherein the front end of the infant carrier body has a plurality of engaging members, one of which is detachably connected to the second connecting mechanism of the connecting structure.

[0089] In one embodiment, the plurality of engaging members include a front engaging member disposed at the front end of the infant carrier body and a rear engaging member disposed at the rear end of the infant carrier body, wherein the width of the second connecting mechanism in the left-right direction is greater than the width of the rear engaging member in the left-right direction.

[0090] In one embodiment, the front end of the infant carrier body has an abutment ramp for abutting against the car seat.

[0091] In one embodiment, the bottom surface of the infant carrier body has a mounting groove, the front engaging member is located in the mounting groove, and when the connecting structure is connected to the infant carrier body, the base assembly engages in the mounting groove.

[0092] In the connection structure and infant carrier having the connection structure according to the embodiments of the present invention, 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 latching member on the infant carrier body, when it is necessary to install the infant carrier body onto the car seat, the infant carrier body can be directly connected to the base assembly via the second connection mechanism first, and then the base assembly can be connected to the car seat via the first connection mechanism; or, the base assembly can be connected to the car seat via the first connection mechanism first, and then the infant carrier body can be connected to the base assembly via the second connection mechanism to achieve the connection between the infant carrier body and the car seat. Furthermore, when it is necessary to carry the infant carrier body separately, the infant carrier body can be directly detached from the base assembly without carrying the entire connection structure, thus effectively reducing the burden on the user when carrying the infant carrier body.

[0155] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0156] Figure 1 A perspective view of an infant carrier 1000 according to an embodiment of the present invention is shown. The infant carrier 1000 may include an infant carrier body 100 and a connecting structure 200 according to an embodiment of the present invention. The connecting structure 200 will be described in conjunction with the description of the infant carrier 1000 below.

[0157] See Figures 1 to 5 In one embodiment, the infant carrier body 100 is described using an infant safety carrier as an example. The infant safety carrier has multiple engaging members, one of which is detachably connected to the connection structure 200 provided in one embodiment of the present invention. Depending on the location of the engaging members, they can be divided into a front engaging member 101 and a rear engaging member 102. The front engaging member 101 is located at the front end of the bottom of the infant safety carrier, and the rear engaging member 102 is located at the rear end of the bottom of the infant safety carrier. Both the front engaging member 101 and the rear engaging member 102 are rod-shaped. The infant safety carrier is detachably connected to the connection structure 200 provided in one embodiment of the present invention via the front engaging member 101. The connection structure 200 can also be detachably connected to a car seat 2000, thereby allowing the infant safety carrier to be installed on the car seat 2000. Specifically, the bottom of the infant carrier body 100 is provided with two mounting ribs 104, which are spaced apart in the left-right direction. This creates a mounting groove 105 between the two ribs. Both the front latching member 101 and the rear latching member 102 are located within the mounting groove 105. The width of the mounting groove 105 at the front latching member 101 is different from the width of the mounting groove 105 at the rear latching member 102 to avoid confusion regarding the front-back direction when the infant 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 latching member 101 is greater than the width of the mounting groove 105 at the rear latching member 102. In other words, the length W3 of the front latching member 101 is greater than the length W2 of the rear latching member 102 (see...). Figure 4It should be noted that the left and right directions here can be referred to as the second direction F2 described below. It should also be noted that the terms "front end" and "rear end" are distinguished based on the infant's lying position within the infant car seat. For example, "front end" refers to the end of the car seat where the infant's feet rest, while "rear end" refers to the end where the infant's head rests.

[0158] To enhance the safety of infants and toddlers riding in infant car seats, infant car seats are typically installed rear-facing in the 2000mm position of the car seat (see [reference]). Figure 5 It can be understood that when an infant is seated in a car seat, their face is turned away from the direction the car is traveling, which is equivalent to their face facing the rear of the vehicle. In one embodiment, such as Figure 1 and Figure 5 As shown, the front end of the infant car seat has an abutment ramp 103. When the infant car seat is installed on the car seat 2000, the abutment ramp 103 abuts against the backrest of the car seat 2000, thereby improving the stability of the infant car seat installed on the car seat 2000. Of course, in another embodiment, as... Figures 33 to 35 As shown, the front end of the infant car seat is provided with a stop member 106, and the front end of the stop member 106 has a vertical abutment surface 1061, which is used to abut against the backrest of the car seat 2000 (see...). Figure 36 and Figure 37 This increases the contact area between the infant car seat and the backrest of the car seat 2000, preventing the infant car seat from tipping backward relative to the car seat 2000 and improving the safety of the infant car seat.

[0159] See Figure 5 One embodiment of this utility model provides a connection structure 200 for connecting an infant carrier body 100 (e.g., 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. The first connection mechanism 40 is detachably connected to the car seat 2000, and the second connection mechanism 50 is detachably connected to the front latching member 101 on the infant carrier body 100. Further, the shape of the second connection mechanism 50 is configured to connect to the front latching member 101. In this embodiment, to avoid misconnection (e.g., connecting the rear latching member 102 to the second connection mechanism 50), in one embodiment, the width W1 of the second connection mechanism 50 in the left-right direction (i.e., the width W1 of the base assembly 20 in the left-right direction at the second connection mechanism 50) is greater than the length W2 of the rear latching member 102 in the left-right direction (see...). Figure 4 This prevents the rear latching member 102 from connecting to the second connecting mechanism 50. It should be noted that in another embodiment, the second connecting mechanism 50 may engage with the rear latching member 102; or, in some other embodiments, the second connecting mechanism 50 may engage with either the front latching member 101 or the rear latching member 102, and this invention does not limit the scope of the invention.

[0160] In the aforementioned 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 latching member 101 on the infant carrier body 100, when it is necessary to install the infant carrier body 100 onto the car seat 2000, the infant carrier body 100 can be directly connected to the base assembly 20 via the second connection mechanism 50, and then the base assembly 20 can be connected to the car seat 2000 via the first connection mechanism 40; or, the base assembly 20 can be connected to the car seat 2000 via the first connection mechanism 40, and then the infant carrier body 100 can be connected to the base assembly 20 via the second connection mechanism 50 to achieve the connection between the infant carrier body 100 and the car seat 2000. Furthermore, when it is necessary to carry the baby carrier body 100 separately, the baby carrier body 100 can be directly separated from the base assembly 20 without having to carry the entire connecting structure 200. This effectively reduces the burden on the user when carrying the baby carrier body 100.

[0161] See 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 sleeved on the outside of the first base 201. Alternatively, in another embodiment, the first base 201 is slidably sleeved on the outside of the second base 202. In yet another embodiment, the first base 201 and the second base 202 are fixedly connected and cannot slide relative to each other. (Continue to see...) 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. Thus, the length of the base assembly 20 in the front-rear direction (which can be considered the first direction F1) can be adjusted by sliding the second base 202 relative to the first base 201, thereby allowing the connecting structure 200 to 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 7This illustration shows a configuration where a second base 202 is fitted over a first base 201, with a first connecting mechanism 40 connected to the first base 201 and a second connecting mechanism 50 connected to the second base 202. In one embodiment, as... Figure 1 and Figure 4 As shown, to make 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 infant carrier body 100. When the connecting structure 200 is connected to the front engaging member 101 of the infant carrier body 100, the second base 202 of the base assembly 20 engages within the mounting groove 105 of the infant carrier body 100. At this time, the two mounting ribs 104 at the bottom of the infant carrier body 100 are located on both sides of the second base 202 (see Figure 105). Figure 1 ).

[0162] Of course, in another embodiment, such as Figure 33 , Figure 38 and Figure 40 As shown, the width of the second base 202 can be greater than the width of the mounting groove 105 of the infant carrier body 100, or the width of the second base 202 can be greater than the width of the infant carrier body 100. Specifically, the second base 202 is provided with two receiving grooves 204, which are 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 infant 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) engages in the mounting groove 105, and the two mounting ribs 104 are respectively accommodated in the two receiving grooves 204 (see...). Figure 33 This increases the contact area between the infant carrier body 100 and the base assembly 20, improving the stability of the infant carrier body 100. It should be noted that, unless otherwise specified, the directional terms such as "front" and "rear" in the embodiments of this utility model are based on the directions shown in the figures. Arrows B and P in each figure indicate the forward and backward directions, respectively. These directional terms are only used to make the description of the embodiments of this utility model clearer and are not intended to unduly limit the scope of protection of this utility model. Specifically, the forward and backward directions in this embodiment can be referred to as the orientation of a car during normal driving.

[0163] See Figures 6 to 9The first base 201 includes a first upper shell 201A and a first lower shell 201B that are interlocked together. The first upper shell 201A and the first lower shell 201B enclose 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 interlocked together. The second upper shell 202A and the second lower shell 202B enclose a second chamber 202C with an opening. The first chamber 201C and the second chamber 202C communicate through the opening to form a receiving cavity 203.

[0164] See Figures 8 to 11 In one embodiment, the base assembly 20 further includes a fixed frame 210 and a sliding frame 220. Both the fixed frame 210 and the sliding frame 220 are housed within a receiving cavity 203. The fixed frame 210 is connected to a first base 201, and the sliding frame 220 is connected to a second base 202 and slidably connected to the fixed frame 210. The sliding frame 220 is capable of sliding back and forth relative to the fixed frame 210. Alternatively, in another embodiment, the fixed frame 210 is connected to the second base 202, and the sliding frame 220 is connected to the first base 201. Thus, by changing the relative position between the sliding frame 220 and the fixed frame 210, the relative position between the second base 202 and the first base 201 can be changed, which is equivalent to changing the length of the base assembly 20 in the front-back direction (first direction F1).

[0165] See Figure 8 and Figure 9 In one embodiment, the fixing frame 210 is detachably or fixedly disposed in the first chamber 201C; the sliding frame 220 is detachably or fixedly disposed in the second chamber 202C.

[0166] See also Figure 8 and Figure 9 In one embodiment, one of the sliding frame 220 and the fixed frame 210 is provided with a plurality of locking portions 221, which are arranged sequentially at intervals 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 and disengage from the locking portion 221. The locking portion 221 is, for example, a locking hole or a locking tooth. Specifically, this embodiment uses a locking hole as an example for the locking portion 221. When the sliding frame 220 is provided with a plurality of locking holes 221 (see details...), the locking portion 221 is used for further information. Figure 12 and Figure 13 The first locking member 230 is pivotally mounted on the fixed frame 210. Alternatively, when the fixed frame 210 has multiple locking holes 221, the first locking member 230 is pivotally mounted on the sliding frame 220. In this embodiment, referring to reference... Figures 10 to 13The sliding frame 220 is provided with multiple locking holes 221, and the first locking member 230 is pivotally mounted on the fixed frame 210. Specifically, as shown in... Figure 10 and Figure 11 As shown, the first locking part 231 has a guide slope 2311 (see details). Figure 15 The guide ramp 2311 faces forward. When the first locking member 230 engages with the locking hole, that is, when the first locking member 230 extends into the locking hole, the first locking part 231 of the first locking member 230 can restrict the forward extension movement of the sliding frame 220 relative to the fixed frame 210. The guide ramp 2311 of the first locking part 231 can be pushed by the edge of the locking hole 221 to make the first locking part 231 exit the locking hole 221, thereby allowing the sliding frame 220 to retract relative to the fixed frame 210. In other words, when the first locking part 231 of the first locking member 230 is inserted into the locking hole 221, under the action of the guide slope 2311, the sliding frame 220 (i.e., equivalent to the second base 202) is 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 in the front-back direction (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 in the front-back direction (first direction F1).

[0167] Specifically, in this embodiment, such as Figure 10 and Figure 11 As shown, the first locking member 230 is pivotally connected to the fixing frame 210, and the guide slope 2311 faces forward.

[0168] To improve the ease of adjusting the length of the base assembly 20 along the front-to-back direction (first direction F1), such as Figures 8 to 11 As shown, in one embodiment, the base assembly 20 may further include a first unlocking mechanism 240. The first unlocking 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 out of the locking hole 221. Thus, when the first locking portion 231 exits the locking hole 221, the sliding between the sliding frame 220 and the fixed frame 210 is unrestricted, thereby pushing the sliding frame 220 (i.e., equivalent to the second base 202) forward relative to the fixed frame 210 (i.e., equivalent to the first base 201) to increase the length of the base assembly 20.

[0169] See Figure 10 and Figure 11 In one embodiment, the first unlocking mechanism 240 may include a driving member 241. The driving member 241 is slidably disposed within the fixing frame 210 and has a first position and a second position, and the driving member 241 is provided with a driving ramp 2411 (see details). Figure 16 Specifically, the drive member 241 slides on the fixed frame 210 in the front-rear direction (first direction F1). The fixed frame 210 is provided with a first guide hole 214 (see...). Figure 14 The drive component 241 is provided with a guide post 2412 (see...). Figure 16 The guide post 2412 slides with the first guide hole 214 to guide the movement of the drive member 241. More specifically, the first locking member 230 is pivotally connected to the fixing frame 210 and has a locked position and an unlocked position. The first locking member 230 also has a drive portion 232, which abuts against and slides along the drive ramp 2411 to allow the first locking member 230 to switch between the locked and unlocked positions. More specifically, when the drive member 241 is in the first position, the first locking member 230 is in the locked position and is in a locked state. When the drive member 241 moves from the first position to the second position, the drive portion 232 slides along the drive ramp 2411, thereby driving the first locking member 230 to pivot from the locked position to the unlocked position. When the drive member 241 is in the second position, the first locking member 230 is in the unlocked position, and the first locking part 231 disengages from the locking hole 221 to allow the sliding frame 220 to extend forward relative to the fixed frame 210.

[0170] To facilitate the switching of the drive unit 241 between the first and second positions, in one embodiment, such as Figure 8 and Figure 9 As shown, the first release mechanism 240 may further include a first operating member 242, a linkage component 243, and a first traction component 244. Specifically, the first operating member 242 is operably disposed on the second base 202. The linkage component 243 is at least partially located within the first base 201 and connected to the drive member 241. The first traction component 244 is connected to both the first operating member 242 and the linkage component 243. More specifically, when the first operating member 242 is operated, the first operating member 242 can drive the drive member 241 to move from a first position to a second position via the first traction component 244 and the linkage component 243.

[0171] See Figure 8 and Figure 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 on the second base 202 in the front-back direction (first direction F1).

[0172] Specifically, such as Figure 3 and Figure 4 As shown, the second base 202 is provided with an operating hole 2021, which is located on the side of the second base 202 opposite to the first base 201. Figure 8 and Figure 9 As shown, the first operating member 242 passes through the operating hole 2021 and is connected to the first traction sleeve 2442.

[0173] See also Figure 8 and Figure 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. 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 bends and deforms 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.

[0174] Specifically, in this embodiment, the first traction sleeve 2442 is a flexible cable sleeve. It should be noted that the first traction sleeve 2442 can be made of a rigid but flexible material, such as a flexible tubular structure made of metal (e.g., steel) or plastic (e.g., PVC).

[0175] In one embodiment, such as Figure 14 As shown, the mounting bracket 210 is provided with a clearance hole 211, which extends along the sliding direction of the driving member 241. Figure 8 and Figure 9 As shown, the linkage assembly 243 includes a linkage block 2431 and a linkage rod 2432 connected together. The second end 24412 of the first traction rope 2441 is connected to the linkage block 2431, and the linkage rod 2432 passes through the clearance hole 211 and is driven to connect with the drive member 241, so as to allow the first traction assembly 244 to drive the linkage block 2431 to move through the second end 24412, and then drive the drive member 241 to move through the linkage rod 2432.

[0176] In one embodiment, such as Figure 17 As shown, the first operating member 242 is provided with a first fixing part 2421 and a second guide hole 2422. Wherein, as... Figure 8 and Figure 9As shown, the first fixing part 2421 is used to connect to the first 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 engagement of the column 245 and the second guide hole 2422, the movement of the first operating member 242 can be prevented from deviating. In this embodiment, there are two second guide holes 2422, which are distributed on both sides of the first fixing part 2421. The column 245 is formed by a threaded connector (e.g., screw, bolt, etc.) connected to the second base 201. There are two columns 245, and each column 245 is guided and engaged with the corresponding second guide hole 2422.

[0177] See you again Figure 8 and Figure 9 In one embodiment, the first release mechanism 240 further includes a first reset member 250, which abuts against the linkage assembly 243 to drive the linkage assembly 243 to reset, thereby keeping the driving member 241 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 also includes an operation reset member (not shown in the figure), which abuts against the first operation member 242 to drive the first operation member 242 to reset.

[0178] See also Figure 8 and Figure 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, for driving the first locking member 230 to reset so that the first locking member 230 is held 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.

[0179] The following is combined Figures 8 to 11 This will explain the working principle and process of the first release mechanism 240.

[0180] See Figure 10 Specifically, when it is necessary to reduce the length of the base assembly 20 in the front-rear direction, the user can directly push the second base 202 backward. The edge of the locking hole 221 abuts against the guide slope 2311 of the first locking part 231, causing the first locking part 231 to disengage from the locking hole 221, thereby allowing the sliding frame 220 to retract relative to the fixed frame 210, thereby shortening the length of the base assembly 20 in the front-rear direction (first direction F1).

[0181] See Figure 8 and Figure 9 When it is necessary to increase the length of the base assembly 20 in the front-to-back direction, the user needs to push the first operating member 242 backward in the front-to-back direction. When the first operating member 242 moves backward, it will cause the first end 24421 of the first traction sleeve 2442 to move together, causing the first traction sleeve 2442 to bend, thereby causing the first traction rope 2441 to bend along with the first traction sleeve 2442. Since the first end of the first traction rope 2441 is fixed, when the first traction rope 2441 bends, the distance between the first end and the second end 24412 shortens, causing the second end 24412 to move closer to the first end (i.e., the second end 24412 moves forward in the front-to-back direction). In other words, when the first operating member 242 moves backward, it will cause the first sleeve end 24421 of the first traction sleeve 2442 to move together, increasing the distance between the first sleeve end 24421 and the first rope end. The length of the first traction rope 2441 located between the first sleeve end 24421 and the second sleeve end 24422 remains unchanged. Therefore, the distance between the second sleeve end 24422 and the second rope end 24412 shortens, which is equivalent to the second rope end 24412 moving forward in the front-back direction. Thus, the second rope end 24412 can drive the linkage assembly 243 to move forward in the front-back direction, which is also considered as driving the driving member 241 to move forward, causing the driving member 241 to move from the first position to the second position. Since the driving inclined surface 2411 abuts against the driving part 232, when the driving member 241 moves forward, the first locking member 230 can rotate counterclockwise around the first connecting member 223 (from...). Figure 10 state towards Figure 11 (State switching) to disengage the first locking part 231 from the locking hole 221, which is equivalent to moving the first locking member 230 from the locked position (see Figure 10 To the unlock position (see) Figure 11 Switching. At this time, the relative movement between the sliding frame 220 and the fixed frame 210 is unrestricted, and the length of the base assembly 20 can be freely adjusted, for example, the length of the base assembly 20 can be increased.

[0182] Once the sliding frame 220's position relative to the fixed frame 210 is confirmed (equivalent to the second base 202's position relative to the first base 201 being confirmed), the first operating member 242 is released, and the first reset member 250 resets to push the linkage assembly 243 backward in the front-back direction, thereby causing the driving member 241 to move backward, equivalent to moving the driving member 241 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 (from...). Figure 11 state towards Figure 10(State switching) so that the first locking part 231 extends into the locking hole 221, which is equivalent to changing the first locking member 230 from the unlocked position (see Figure 11 To the locked position (see) Figure 10 Switching. 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., the length of the base assembly 20 is restricted).

[0183] See Figure 41 and Figure 42 In other embodiments, the first release mechanism 240 includes a drive member 241, a first operating member 242, and a linkage assembly 243. This embodiment (see...) Figure 41 and Figure 42 ) and the above embodiments (see Figure 10 and Figure 11 At least the following differences exist.

[0184] like Figure 41 and Figure 42As shown, in another embodiment, the first base 201 (such as the first lower shell 201B) is provided with an operation hole 2021. The first operating member 242 is movably disposed at the operation 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-back direction (first direction F1). The linkage component 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 or pulled along the front-back direction, the first operating member 242 drives the linkage component 243 to move, thereby driving the driving member 241 to move from the first position to the second position. It should be noted that in this embodiment, the linkage component 243 may 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 is held 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, the extension direction of the driving groove 2413 being approximately the same as the movement direction of the driving member 241, that is, the driving groove 2413 extends along the front-back direction (first direction F1). The fixing frame 210 is provided with an abutment portion 215, which at least partially extends into the driving groove 2413. The first reset member 250 is disposed in the driving groove 2413, one end of the first reset member 250 abuts against the abutment portion 215, and the other end of the first reset member 250 abuts against the inner sidewall of the driving groove 2413 facing away from the driving inclined surface 2411. Thus, the first reset member 250 pushes the driving member 241 to move backward along the front-back direction. The first release mechanism 240 in this embodiment has a simple structure and is relatively easy to operate.

[0185] See also Figure 41 and Figure 42 In another embodiment, the base assembly 20 further includes an elastic element 350. A first abutment 206 is provided in the first base 201, and a second abutment 207 is provided in the second base 202. The elastic element 350 abuts between the first abutment 206 and the second abutment 207, causing the first base 201 and the second base 202 to tend to move away from each other. Thus, when the first locking part 231 of the first locking member 230 is withdrawn from the locking hole 221, the relative movement between the sliding frame 220 and the fixed frame 210 is unrestricted. Therefore, under the pushing action of the elastic element 350, the second base 202 can directly slide relative to the first base 201, thereby automatically increasing the length of the base assembly 20.

[0186] Specifically, such as Figure 41 and 42As shown, at least one of the first abutment 206 and the second abutment 207 is provided with a guide rod 208. The elastic element 350, for example, is a compression spring, sleeved on the guide rod 208, with both ends of the elastic element 350 abutting against the first abutment 206 and the second abutment 207 respectively. Thus, when the sliding frame 220 moves relative to the fixed frame 210 to reduce the length of the base assembly 20, the guide rod 208 can prevent the elastic element 350 from shifting or bending during compression.

[0187] like Figure 10 and Figure 11 As shown, in one embodiment, to prevent the sliding frame 220 from shifting relative to the fixed frame 210 and to prevent them from separating due to excessive sliding, 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 disposed within the first limiting groove 222. The first locking member 230 is pivotally connected to the fixed frame 210 via the first connecting member 223. In this embodiment, the fixed frame 210 is also provided with a second limiting groove 212, which extends along the sliding direction of the sliding frame 220. A second connecting member 213 for connecting the sliding frame 220 is slidably disposed within the second limiting groove 212. In this way, the sliding frame 220 can slide more stably relative to the fixed frame 210, further preventing the sliding frame 220 from shaking or shifting relative to the fixed frame 210. In this embodiment, the second connector 213 is located slightly above and behind the first connector 223 (i.e., above and behind the first connector 213). The first locking portion 231 of the first locking member 230 is located behind the first connector 223, and at least a portion of the first locking member 230 is located below the second connector 213. When the first locking member 230 is in the locked position, the first locking member 230 and the second connector 213 are spaced apart. When the first locking member 230 is pushed and pivoted to the unlocked position by the driving member 241, the first locking member 230 is stopped by the second connector 213, thereby restricting further pivoting of the first locking member 230, and thus restricting the travel of the driving member 241.

[0188] See Figure 8 and Figure 9In one embodiment, the accommodating cavity 203 is provided with two sliding frames 220 and two fixed frames 210, which are respectively corresponding to each other and 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 generally perpendicular to the first direction F1. Further, there are two first locking members 230 and two driving members 241. 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 all arranged between the two fixed frames 210, and the two ends of the linkage rod 2432 are respectively drivenly connected to the two driving members 241. Thus, when the first operating member 242 is pushed, under the action of the linkage component 243, the two driving members 241 can be switched from the first position to the second position at the same time, which is equivalent to simultaneously driving the two first locking members 230 to switch from the locked position to the unlocked position.

[0189] It should be noted that, unless otherwise specified, the directional terms such as "left" and "right" in the embodiments of this utility model are based on the directions shown in the figures. Arrows L and R in each figure indicate the left and right directions, respectively. These directional terms are only used to make the description of the embodiments of this utility model clearer and are not intended to unduly limit the scope of protection of this utility model. Specifically, the left and right directions in this embodiment can be specifically referred to as the width of a car.

[0190] See Figure 5 As shown, when using the aforementioned connection structure 200, the base assembly 20 can first be installed onto the car seat 2000 via the first connection mechanism 40. Subsequently, by manipulating (e.g., pressing or pushing) the first operating member 242, the first locking member 230 can be switched to the unlocked position, thereby releasing the restriction on the sliding frame 220. The second base 202 can then move forward relative to the first base 201, allowing the base assembly 20 to have a larger length, thus providing ample operating space between the base assembly 20 and the backrest of the car seat 2000 for quickly installing the infant carrier body 100 onto the base assembly 20 via the second connection mechanism 50. After the infant carrier body 100 is installed onto the base assembly 20, its position can be adjusted via the base assembly 20 as needed. For example, when it is necessary to move the infant carrier body 100 backward so that the abutment slope 103 of the infant carrier body 100 can abut against the backrest of the car seat 2000, the second base 202 can be pushed backward directly. It is evident that when the aforementioned base assembly 20 is a telescopic structure, it facilitates the rapid installation of the infant carrier body 100, and also allows the connecting structure 200 to be adapted to car seats 2000 of different sizes.

[0191] See Figure 18 and Figure 19 or Figure 34 and Figure 35 In one embodiment, the first connecting mechanism 40 is movably connected to the base assembly 20 and has an unfolded state and a folded state. When the first connecting mechanism 40 is in the unfolded state, the projected length of the connecting structure 200 on the horizontal plane is greater than the projected 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 approximately parallel to the front-back direction (i.e., the first direction F1) and parallel to the left-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 overlaps with the base assembly 20 in the first direction F1; when the first connecting mechanism 40 is in the unfolded 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 installed on the base assembly 20.

[0192] It should be noted that the aforementioned "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.

[0193] See Figure 8 , Figure 9 or Figure 21 , Figure 22 In one embodiment, the first connecting mechanism 40 may include a plug connecting assembly 410 and at least one connecting plug 420. The plug connecting assembly 410 is pivotally connected to the base assembly 20, specifically to the first base 201. The connecting plug 420 is fixedly connected to the plug connecting assembly 410 and is mainly used for detachable connection with the car seat 2000. Specifically, there are two connecting plugs 420, which are respectively disposed at both ends of the plug connecting assembly 410. More specifically, in one embodiment, when the first connecting mechanism 40 is in the deployed state, the included angle α1 between the connecting plug 420 and the base assembly 20 is approximately 180 degrees (see...). Figure 8 and Figure 18 or Figure 34 and Figure 38 When the included angle α1 is approximately 180 degrees, the connecting structure 200 is mainly used to install the infant carrier body 100 onto the car seat 2000 where the seat surface is horizontal (this installation situation can be seen later). Of course, when the first connecting mechanism 40 is in the unfolded state, the included angle α1 can also be greater than 180 degrees, such as 200 degrees, 220 degrees, etc. (see...) Figure 37When the included angle α1 is greater than 180 degrees, the connecting structure 200 is mainly used to install the infant carrier body 100 onto the car seat 2000 with the seat surface in a tilted position (see below for this installation situation). When the first connecting mechanism 40 is in the folded state, the included angle α1 between the connecting plug 420 and the base assembly 20 is approximately 0 degrees (see below for details). Figure 19 or Figure 35 Thus, when it is necessary to use the connecting structure 200 to install the infant carrier body 100 onto the car seat 2000, the first connecting mechanism 40 is directly unfolded to put it in the unfolded state (see...). Figure 18 or Figure 34 The infant carrier body 100 is then connected to the car seat 2000 via the first connecting mechanism 40 and the second connecting mechanism 50. When the connecting structure 200 needs to be carried with the infant carrier body 100, the connection between the infant carrier body 100 and the base assembly 20 is maintained. Then, the connecting plug 420 is rotated to rotate the plug connecting assembly 410 nearly 180 degrees within the first base 201, thereby putting the first connecting mechanism 40 in a folded state, which can be considered as folding it onto the infant carrier body 100 (see...). Figure 19 or Figure 35 This makes it easy to carry.

[0194] See Figure 20 In one embodiment, the first connecting mechanism 40 also has a semi-folded state. When the first connecting mechanism 40 is in the semi-folded state, the included 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 infant 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 assembly 410 rotate relative to each other until the included angle α1 between the connecting plug 420 and the base assembly 20 is an acute angle. This reduces the area occupied by the connecting structure 200 on the car seat 2000, thus not affecting the normal use of the car seat 2000.

[0195] As described above, the first connecting mechanism 40 has a first pivoting position, a second pivoting position, a third pivoting position, and a fourth pivoting position relative to the base assembly 20. Furthermore, the first connecting mechanism 40 can be locked in each pivoting position, meaning that the first connecting mechanism 40 can be locked in the first pivoting position, the second pivoting position, the third pivoting position, and the fourth pivoting position. Specifically, when the first connecting mechanism 40 is in the first pivoting position (see...), Figure 19 When the first connecting mechanism 40 is in the folded state, the included angle α1 is approximately 0 degrees. When the first connecting mechanism 40 is in the second pivot position (see...), Figure 18 or Figure 36 or Figure 50When the first connecting mechanism 40 is in the deployed state, the included angle α1 is approximately 180 degrees. When the first connecting mechanism 40 is in the third pivot position (see...), Figure 37 or Figure 51 When the first connecting mechanism 40 is in the deployed state, and its extension direction is not parallel to that of the base assembly 20, the included angle α1 is greater than 180 degrees. When the first connecting mechanism 40 is in the fourth pivot position (see...), Figure 20 When the first connecting mechanism 40 is in a half-folded state, the base assembly 20 is adapted to rest against the back of the car seat 2000, and the included angle α1 is greater than 180 degrees.

[0196] See Figure 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 unfolded state or a folded state.

[0197] See Figures 21 to 24 In one embodiment, the plug connection assembly 410 is provided with a limiting groove 430, and the second locking member 270 is a limiting protrusion. The second locking member 270 is movably disposed relative to the plug connection assembly 410, so that the second locking member 270 has a third position extending into the limiting groove 430 and a fourth position retracting from the limiting 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. 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 are rotatably disposed within the first base 201. More specifically, the connector 411 is capable of rotating about the rotation axis X. The connector 411 is provided with a limiting groove 430, and the second locking member 270 is movably disposed relative to the connector 411. The 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 consist of only a complete connecting inner tube with a limiting protrusion in the middle of the connecting inner tube.

[0198] In one embodiment, such as Figure 21 and Figure 24As shown, the limiting groove 430 includes a first groove 431 and a second groove 432, with the first groove 431 and the second groove 432 positioned opposite to each other. When the second locking member 270 extends into the first groove 431, the first connecting mechanism 40 is limited to an unfolded state. When the second locking member 270 extends into the second groove 432, the first connecting mechanism 40 is limited to a folded state. Alternatively, in another embodiment, when the second locking member 270 extends into the first groove 431, the first connecting mechanism 40 may be limited to a folded state, and when the second locking member 270 extends into the second groove 432, the first connecting mechanism 40 may be limited to an unfolded state.

[0199] See Figure 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 a third position. The third reset member 280 is, for example, a spring that abuts against the second locking member 270.

[0200] See Figure 24 In one embodiment, the edges of the first groove 431 and the second groove 432 are respectively provided with guide slopes 433 to allow the second locking member 270 to exit the first groove 431 or the second groove 432 along the guide slopes 433. Thus, when the user needs to change the state of the first connecting mechanism 40, i.e., switch from the folded state to the unfolded state or vice versa, there is no need to release the lock; the connecting plug 420 can be directly rotated to cause the connecting plug 420 to drive the connecting inner tube 412 and the connector 411 to rotate around the rotation axis XX, thereby improving the convenience of switching between states. Furthermore, when the infant carrier body 100 is installed on the car seat 2000 via the connecting structure 200, if the car accelerates rapidly, the infant carrier body 100 and the base assembly 20 will tend to tilt backward in a clockwise direction under the action of inertial force. At this time, under the action of the guide slope 433, the second locking member 270 can be disengaged from the first groove 431, and the base assembly 20 will tend to rotate relative to the connecting inner tube 412 and the connector 411 around the rotation axis XX, thereby preventing the infant carrier body 100 from separating from the second connecting mechanism 50 when it tilts backward and thus preventing the infant carrier body 100 from detaching from the base assembly 20.

[0201] See Figure 21 and Figure 22In one embodiment, the plug connection assembly 410 further includes an outer connecting tube 413 and a rotation locking mechanism 415. The outer connecting tube 413 is sleeved around the inner connecting tube 412 and fixedly connected to the base assembly 20. The inner connecting tube 412 is rotatable relative to the outer connecting tube 413. The wall of the outer connecting tube 413 is provided with a socket for a second locking member 270 to pass through. After passing through the socket, the second locking member 270 can extend into the first groove 431 or the second groove 432. The rotation locking mechanism 415 is connected between the inner connecting tube 412 and the outer connecting tube 413. The rotation locking mechanism 415 has a locked state and an unlocked state. When the rotation locking mechanism 415 is in the locked state, the inner connecting tube 412 is restricted from rotating relative to the outer connecting tube 413. When the rotation locking mechanism 415 is in the unlocked state, the inner connecting tube 412 is allowed to rotate relative to the outer connecting tube 413. The rotation locking mechanism 415 includes a second locking member 270 disposed on the inner connecting tube 412 and a second mating part 4131 disposed on the outer connecting tube 413. The second locking member 270 can lock into the second mating part 4131 to restrict the rotation of the inner connecting tube 412 relative to the outer connecting tube 413. How the second locking member 270 and the second mating part 4131 achieve the locking engagement will be described in detail below, and will not be repeated here.

[0202] See Figure 21 and Figure 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, and 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. This improves the smoothness of rotation of the connecting inner tube 412, and at the same time, increases the service life of both the connecting inner tube 412 and the connecting outer tube 413. 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 the elastic arm 4141 is provided with a limiting structure 4142. The connecting outer tube 413 is provided with a bayonet for engaging with the limiting structure 4142. In one embodiment, the connecting outer tube 413 and the connecting inner tube 412 are made of metals such as steel or aluminum, and the wear-resistant sleeve 414 is made of materials such as resin or polyethylene. The hardness of the wear-resistant sleeve 414 is less than that of the connecting outer tube 413 or the connecting inner tube 412.

[0203] See Figures 43 to 46In another embodiment, the second locking member 270 may be, for example, a sleeve structure. The second locking member 270 is sleeved on the outside of 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, the second locking member 270 is provided with a limiting portion 271, which is used to restrict the rotation of the second locking member 270 relative to the connecting inner tube 412. The wall of the connecting inner tube 412 is provided with a strip-shaped hole 4121, and the limiting portion 271 may be, for example, a protrusion formed on or detachably connected to the second locking member 270, which passes through the strip-shaped hole 4121 to extend into the interior of the connecting inner tube 412. Thus, when one of the connecting inner tube 412 and the second locking member 270 rotates, the other rotates accordingly, without affecting the sliding of the second locking member 270 on the connecting inner tube 412. Figure 45 and Figure 46 As shown, the second locking member 270 is further provided with a locking part 272, and the connecting outer tube 413 is provided with a second mating part 4131, which is used to lock into the locking part 272. Specifically, when the second locking member 270 is in the third position (see...), Figure 45 The locking part 272 engages with the second mating part 4131, fixing the inner tube 412 and the outer tube 413 relatively. When the second locking part 270 is in the fourth position (see...), Figure 46 The locking part 272 separates from the second mating part 4131, allowing the inner connecting tube 412 and the outer connecting tube 413 to rotate relative to each other. It should be noted that one of the locking part 272 and the second mating part 4131 is a locking protrusion, and the other is a locking recess. The locking recess engages with the locking protrusion to achieve relative fixation between the second locking member 270 and the outer connecting tube 413.

[0204] See Figure 43 and Figure 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 a third position to a fourth position. Thus, the user can directly control the position of the second locking member 270 via the third release mechanism 370. Specifically, as... Figures 43 to 46As shown, the third unlocking mechanism 370 includes a drive wheel 371, a third operating member 372, and a third traction assembly 373. More specifically, the second locking member 270 is provided with a toothed groove 273, and the drive wheel 371 is rotatably disposed within the base assembly 20 and is provided with meshing teeth 3711. The drive wheel 371 drives the second locking member 270 to move by meshing with the toothed groove 273 through the meshing teeth 3711. 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 drive wheel 371. When the third operating member 372 is operated, the third operating member 372 can drive the drive wheel 371 to rotate through the third traction assembly 373, thereby moving the second locking member 270 from the third position to the fourth position.

[0205] like Figures 43 to 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 flexible 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 drive 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 deforms to cause the third traction rope 3731 to pull the drive wheel 371 to rotate, thereby driving the second locking member 270 to move from the third position to the fourth position.

[0206] It should be noted that the third traction sleeve 3732 mentioned above is the same as the first traction sleeve 2442, both being flexible cable sleeves.

[0207] See Figures 43 to 46In another embodiment, the first base 201 is generally T-shaped. The drive wheel 371 is rotatably disposed in the vertical part of the T-shaped structure, and the connecting outer tube 413 is fixedly disposed in the horizontal part of the T-shaped structure. The third operating member 372 moves along the left-right direction (second direction F2) on the horizontal part of the T-shaped structure. When it is necessary to switch the second locking member 270 from the third position to the fourth position, the third operating member 372 is pushed towards the inside of the base assembly 20 along the second direction F2. 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 bends with the third traction sleeve 3732. Since the second end 37312 of the third traction rope 3731 is fixed, when the third traction rope 3731 bends, the distance between the first end 37311 and the second end 37312 shortens, causing the first end 37311 to move closer to the first sleeve end 37321, thereby driving the drive wheel 371 to rotate. In other words, when the third operating member 372 is pushed inward toward 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 end 37312 increases (see...). Figures 44 to 46 Meanwhile, under the transmission action of the third traction sleeve 3732, the length of section L4 of the third traction rope 3731 between the first rope end 37311 and the first sleeve end 37321 decreases (see...). Figures 44 to 46 The first rope end 37311 pulls the drive wheel 371 to rotate, so that the second locking member 270 switches from the third position to the fourth position.

[0208] 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 single, continuous connecting inner tube 412, i.e., a single long section.

[0209] See also Figures 43 to 46 In another embodiment, two connecting outer tubes 413 are provided, spaced apart along the length of the connecting inner tube 412. Two second locking members 270 are provided, located between the two connecting outer tubes 413 and corresponding to each of the two connecting outer tubes 413. Two third unlocking mechanisms 370 are provided and operably connected to their respective second locking members 270. Specifically, the two drive wheels 371 in the two third unlocking mechanisms 370 are engaged. Therefore, when one drive wheel 371 rotates, it drives the other drive wheel 371 to rotate, causing the two second locking members 270 to move simultaneously. Thus, the user can simultaneously change the position of the two second locking members 270 by manipulating either of the third operating members 372.

[0210] like Figures 43 to 46 As shown, in another embodiment, in order to enable the second locking member 270 to automatically reset, that is, to 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 spaced apart, and the eighth reset member 380 abuts between the two second locking members 270 to provide elastic restoring force to the two second locking members 270, thereby keeping both second locking members 270 in the third position.

[0211] The following is combined Figures 43 to 46 To illustrate the switching process between the unfolded state and the folded state of the first connecting mechanism 40 provided according to another embodiment of the present invention.

[0212] When the first connecting mechanism 40 is in the extended state, the second locking member 270 is in the third position. At this time, the locking part 272 of the second locking member 270 engages with the second mating part 4131 on the connecting outer tube 413 (see...). Figure 43 and Figure 45 The inner tube 412 and the outer tube 413 are kept relatively fixed.

[0213] When it is necessary to switch the first connecting mechanism 40 from the unfolded state to the folded state, the user can directly push any of the third operating members 372 inwards. For example, pushing the third operating member 372 located on the left side inwards will cause the third operating member 372 to move to the right in the left-right direction (second direction F2). Under the transmission action of the third traction rope 3731 and the third traction sleeve 3732, the drive wheel 371 located on the left side can be rotated counterclockwise. Since the drive wheel 371 meshes with the toothed groove 273 on the second locking member 270, when the drive wheel 371 on the left side rotates counterclockwise, it will drive the second locking member 270 on the left side to move to the right, causing the locking part 272 of the second locking member 270 to separate from the second mating part 4131 on the connecting outer tube 413 (see...). Figure 46 When the locking part 272 disengages from the second mating part 4131, the rotation of the inner connecting tube 412 is unrestricted, and the user can hold the connecting plug 420 to drive the inner connecting tube 412 to rotate around the rotation axis XX. It should be noted that since the two drive wheels 371 are engaged, when the left drive wheel 371 rotates counterclockwise, the right drive wheel 371 will rotate clockwise. This will cause the right second locking member 270 to move to the left, so that the locking part 272 of the second locking member 270 disengages from the second mating part 4131 on the corresponding outer connecting tube 413.

[0214] When the first connecting mechanism 40 switches to the folded state, the second mating part 4131 on the connecting outer tube 413 aligns again with the locking part 272 of the second locking member 270. Since an 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 moves to the left and the second locking member 270 on the right moves to the right. In this way, the locking parts 272 of the two second locking members 270 will once again engage with the corresponding second mating part 4131 on the connecting outer tube 413, thereby restricting the rotation of the two second locking members 270 and the connecting inner tube 412, and thus keeping the first connecting mechanism 40 in the folded state.

[0215] Similarly, when it is necessary to switch the first connecting mechanism 40 from the folded state to the unfolded state, its working principle is the same as when the first connecting mechanism 40 switches from the unfolded state to the folded state, but the working process is reversed, and will not be described again here.

[0216] See Figure 47 In another embodiment, the second locking member 270 and the third unlocking mechanism 370 can be omitted. In this case, the inner connecting tube 412 can rotate freely relative to the outer connecting tube 413. When the first connecting mechanism 40 can freely switch between the folded and unfolded states, the connecting structure 200, after connecting the infant car seat 200 to the car seat 2000, will tend to tilt backward in a clockwise direction relative to the seat 2000 under the action of inertial force if the car accelerates rapidly. To avoid the above-mentioned problems, refer to [reference needed]. Figures 48 to 51 The connecting structure 200 also includes an abutment rod 60 for abutting against the backrest of the car seat 2000. Optionally, the abutment rod 60 may be directly mounted on the base assembly 20 (e.g., the first base 201). Alternatively, the abutment rod 60 may pass through the base assembly 20 and connect to the connecting outer tube 413. Or, the abutment rod 60 may pass through the base assembly 20 and the connecting outer tube 413 and connect to the connecting inner tube. Because the angle between the abutment rod 60 and the base assembly 20 remains fixed, the base assembly 20 cannot tilt backward relative to the car seat 2000 when the abutment rod 60 abuts against the backrest, thus improving the stability of the infant car seat after installation.

[0217] It should be noted that the abutment member 60 can be fixedly installed on the base assembly 20, the connecting outer tube 413, or the connecting inner tube 412. Alternatively, the abutment member 60 can be pivotally connected to the base assembly 20, the connecting outer tube 413, or the connecting inner tube 412. When the abutment member 60 is pivotable relative to the base assembly 20, the connecting outer tube 413, or the connecting inner tube 412, the base assembly 20 also has another locking mechanism for locking the abutment member 60. Furthermore, the abutment member 60 can also be detachably connected to the base assembly 20, the connecting outer tube 413, or the connecting inner tube 412.

[0218] Of course, such as Figure 49 As shown, in another embodiment where the base assembly 20 has a second locking member 270 and a third unlocking mechanism 370, the connecting structure 200 may still include the aforementioned abutment member 60, meaning that the base assembly 20 is still provided with the aforementioned abutment member 60. Compared to the case where the abutment member 60 is not provided, the abutment member 60 indirectly increases the contact area between the infant car seat and the backrest, thus further improving the stability of the infant car seat after installation. It should be noted that when the connecting structure 200 includes the abutment member 60, that is, when the base assembly 20 is provided with the abutment member 60, the abutment member 106 at the front end of the infant carrier body 100 can be omitted.

[0219] See Figure 52 In some embodiments where the abutment member 60 is provided, the connecting structure 200 also includes a safety harness 70. The safety harness 70 includes a fixing part 710 and a connecting part 720. The fixing part 710 is connected to the abutment member 60, and the connecting part 720 is used to connect to the anchor point of the car seat 2000. This ensures the stability of the connecting structure 200 and the infant car seat 2000, preventing forward / backward and / or lateral sliding. Specifically, the fixing part 710 and / or the connecting part 720 are provided with connecting members 730, such as hooks, loops, etc., which improves the convenience and stability of the connection. More specifically, the safety harness 70 is provided with an adjuster 80 for adjusting the usable length of the safety harness 70.

[0220] See Figure 53 and Figure 54The abutment member 60 has a through portion 601. 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 carrier. The connecting portion 720 is still used to connect to the anchor point of the car seat 2000. Specifically, in this embodiment, the safety strap 70 has a Y-shaped structure, that is, one end of the safety strap with the connecting portion 720 extends outward with two branches, thereby forming two fixing portions 710. The two fixing portions 710 drive the two branches to surround the infant safety carrier, that is, to connect to the connecting buckle 107 on the back of the infant safety carrier in a "hugging" manner. Figure 4 and Figure 6 As shown, in one embodiment, the first base 201 is generally T-shaped, and the second base 202 is generally rectangular. The width of the second base 202 in the left-right direction can be considered as the width W1 of the second connecting mechanism 50. Of course, as... Figure 38 and Figure 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 open end is formed on each side of the base assembly 20. (See also 45 and...) Figure 46 Since the plug connection assembly 410 is located on the horizontal part of the T-shaped structure of the first base 201 (the connecting outer tube 413 is fixedly installed on the horizontal part of the first base 201, and the connecting inner tube 412 is rotatably installed on the horizontal part of the first base 201), and the end of the connecting inner tube 412 is connected to the connecting plug 420, when the connecting inner tube 412 is rotated to make the first connecting mechanism 40 folded, at least a portion of the connecting plug 420 is blocked at the opening of the slot 205 (see...). Figure 39 This allows users to easily reach into the slot 205 to hold the horizontal part of the T-shaped structure of the first base 201 or the connector 420, thus improving the portability of the connection structure 200.

[0221] See Figures 55 to 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 set at an angle, so that when the infant safety carrier is engaged with the second connecting mechanism 50, the bottom surface of the first base 201 does not contact the car seat 2000. Figure 36 and Figure 37As shown, when the base assembly 20 is connected to the car seat 2000 via the first connecting mechanism 40 (i.e., the connector 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 parts of the housings of the first lower shell 201B and the second lower shell 202B (i.e., the housings excluding the ends of the second lower shell 202B that are away from the first lower shell 201B) are suspended and do not contact the seat portion. This provides space for the connector 420 and the base assembly 20 to bend relative to each other.

[0222] See Figure 3 and Figure 5 Or see Figure 33 and Figure 34 In some of the above embodiments, the bottom of the mounting rib 104 of the infant carrier body 100 has an arc-shaped structure. This allows the user to soothe the infant carrier when it is placed on a horizontal surface by pressing up and down on the end of the carrier. Specifically, the front engaging member 101 can be located in the area between the front end of the arc-shaped structure and the middle of the arc-shaped structure along its circumference. When the front engaging member 101 is connected to the second connecting mechanism 50, the base assembly 20 (receiving groove 204) can support the front end area of ​​the arc-shaped mechanism. Thus, when the infant carrier is connected to the car seat 2000 via the connecting structure 200, the support area of ​​the seat portion of the car seat 2000 on the mounting rib 104 (bottom of the infant carrier) is indirectly increased, making it less prone to back-and-forth swaying after installation.

[0223] Currently, the seat section of car seats 2000 can be roughly divided into two types: one is where the seat section is parallel to the horizontal plane, that is, the seat surface is parallel to the horizontal plane (see...). Figure 36 or Figure 50 Secondly, the seat is tilted relative to the horizontal plane, that is, the seat surface is tilted to the horizontal plane (see...). Figure 37 or Figure 51 Since the connector 420 can rotate with the inner connector 412, when using car seats 2000 with different seat surfaces, the angle α3 between the connector 420 and the base assembly 20 can be changed by rotating the base assembly 20 or the connector 420, so that the infant car seat can be adapted to different car seats 2000. Specifically, as shown... Figure 36 As shown, when the seat is horizontal, the infant car seat is fixed to the car seat 2000 via the connecting structure 200. At this time, the angle α3 between the connecting plug 420 and the base assembly 20 is approximately 180°, and no bending is required between them. Figure 37As shown, when the seat is tilted, to ensure the infant car seat is directly supported on the seat, the base assembly 20 needs to be bent so that the angle α3 between the connector 420 and the base assembly 20 is approximately obtuse. Furthermore, the angle α3 between the connector 420 and the first base 201 can be adjusted adaptively according to different seat tilt angles, thus improving the adaptability of the connection structure 200 to different car seats 2000. In addition, rotating the inner connecting tube 412 to change the angle α3 between the connector 420 and the base assembly 20 can also be used to adjust the tilt angle of the infant car seat relative to the seat, thereby adjusting the pitch angle of the infant car seat relative to the car seat 2000, and consequently changing the infant's position (sitting or lying down) relative to the car seat 2000.

[0224] The connector 420 is, for example, an ISOFIX connector or other suitable connector. Specifically, such as... Figure 26 and Figure 27 As shown, in one embodiment, the connector 420 is an ISOFIX connector. The connector 420 may include a housing 421, a locking hook 422, and a locking member 423. A cavity 4211 is formed within the housing 421, and the end of the housing 421 away from the connector assembly 410 has a locking groove 4212 for accommodating a lever (not shown) on the car seat 2000. The groove wall of the locking groove 4212 has a through hole that connects the locking groove 4212 and the cavity 4211. The locking hook 422 is located within the cavity 4211 and pivotally connected to the housing 421, so that the locking hook 422 has a locked position and an unlocked position. Specifically, when the locking hook 422 is in the locked position (see... Figure 26 The locking hook 422 at least partially blocks the opening of the locking groove 4212 to lock and limit the lever, thereby achieving the connection between the first connecting mechanism 40 and the car seat 2000. When the locking hook 422 is in the unlocked position (see...), Figure 27The locking groove 4212 is open, allowing the locking lever to disengage from the locking hook 422. More specifically, the locking member 423 is located within the cavity 4211 and can slide relative to the locking hook 422 to approach or move away from it. One of the locking hook 422 and the locking member 423 facing the locking hook 422 has a slot 4221, and the other has a block 4231. When the locking hook 422 is in the locked position, the block 4231 engages within the slot 4221 to hold the locking hook 422 in the locked position. When the block 4231 disengages from the slot 4221, the locking hook 422 can pivot to switch to the unlocked position. Furthermore, a seventh reset member (not shown in the figures) is provided within the cavity 4211. This seventh reset member is, for example, a torsion spring. This seventh reset member abuts against the locking hook 422 and is adapted to bias the locking hook 422 to rotate towards the unlocked position. Therefore, when the card block 4231 retracts from the card slot 4221, the lock hook 422 automatically switches to the unlocking position under the action of the seventh reset component, so as to facilitate and smoothly unlock the device and prevent the lock hook 422 from locking up.

[0225] See Figure 28 and Figure 29 In one embodiment, the second connecting 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 receive the front locking member 101 of the infant carrier body 100, and the locking hook 510 is pivotally connected to the base assembly 20 and has a locked position and an unlocked position. When the locking hook 510 is in the locked position, the locking hook 510 extends at least partially into the slot of the limiting groove 520 (see...). Figure 28 This locks and limits the front latch 101. When the latch hook 510 is in the unlocked position, the opening of the limiting groove 520 is open (see...). Figure 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, i.e. the upper surface of the base assembly 20, abut against the lower surface of the infant carrier body 100 to prevent the infant carrier body 100 from pivoting relative to the base assembly 20.

[0226] See Figure 28 and Figure 29 In one embodiment, the groove wall of the limiting groove 520 is provided with a through hole (not shown in the figure), which connects the receiving cavity 203 and the limiting groove 520. Specifically, the engaging hook 510 is provided with a receiving groove 511 adapted to the front engaging member 101. The receiving groove 511 is U-shaped and its opposite side walls respectively form a locking wall surface 5111 and a pushing wall surface 5112 (see figure). Figure 30The abutting wall 5112 is adapted to be abutted by the front engaging member 101 to drive the engaging hook 510 to pivot from the unlocked position to the locked position. A portion of the engaging hook 510 is received within the receiving cavity 203 and pivotally connected to the side wall of the receiving cavity 203 via a pivot shaft 530. Specifically, in this embodiment, the engaging hook 510 is pivotally connected to the sliding frame 220 via a pivot shaft (see...). Figure 8 and Figure 9 Furthermore, the sliding frame 220 is provided with a locking groove 224 (see...). Figure 12 and Figure 13 The limiting groove 520 forms an engaging portion 2023 on the side wall of the receiving cavity 203 (see...). Figure 10 and Figure 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 locked position, the locking wall surface 5111 is located within the limiting groove 520 and blocks the opening of the limiting groove 520. When the engaging hook 510 is in the unlocked position, the pushing wall surface 5112 is located within the limiting groove 520, and the locking wall surface 5111 is located within the receiving cavity 203.

[0227] In one embodiment, such as Figure 28 As shown, when the locking hook 510 is in the locked position, the front locking member 101 abuts against the pushing wall surface 5112, and a gap is formed between the locking wall surface 5111 and the front locking member 101. In this way, when the locking hook 510 pivots about the pivot axis 530 to switch the locking hook 510 to the unlocking position, it is convenient for the front locking member 101 to disengage from the locking hook 510.

[0228] In one embodiment, the base assembly 20 further includes a locking and retaining mechanism 290. For example... Figure 8 , Figure 9 as well as Figure 28 , Figure 29 As shown, the locking and retaining mechanism 290 is movably disposed within the receiving cavity 203. When the engaging hook 510 is driven to the locked position, the locking and retaining mechanism 290 is used to lock the engaging hook 510 in the locked position.

[0229] See Figure 8 and Figure 9In one embodiment, the locking and retaining mechanism 290 may include a limiting member 291, which is movably disposed within the receiving cavity 203 and has a fifth position and a sixth position. Specifically, the limiting member 291 is pivotally connected to the bottom wall of the base assembly 20 around the first pivot point Q1. One of the limiting member 291 and the engaging hook 510 has a locking recess 513, and the other has a first engaging portion 2911. In other words, when the limiting member 291 has the locking recess 513, the engaging hook 510 has the first engaging portion 2911; or, when the engaging hook 510 has the locking recess 513, the limiting member 291 has the first engaging portion 2911. Specifically, in this embodiment, the engaging hook 510 has the locking recess 513, and the locking recess 513 is a locking notch; the limiting member 291 has the first engaging portion 2911, which is a protrusion. More specifically, when the limiting member 291 is in the fifth position, the locking recess 513 engages with the first mating part 2911 to lock the engaging hook 510 in the locked position. When the limiting member 291 is in the sixth position, the locking recess 513 separates from the first mating part 2911 and the engaging hook 510 is in the unlocked position.

[0230] See also Figure 8 and Figure 9 In one embodiment, the locking and retaining mechanism 290 further includes a fifth reset member 292. The fifth reset member 292 provides an elastic restoring force to the limiting member 291 to drive the limiting member 291 to switch to a fifth position. The fifth reset member 292 is, for example, a spring, so that when the engaging hook 510 pivots from the unlocked position to the locked position, the limiting member 291 can automatically switch to the fifth position under the action of the fifth reset member 292, so that the first mating portion 2911 of the limiting member 291 extends into the locking recess 513 of the engaging hook 510 to lock the engaging hook 510 and keep the engaging hook 510 in the locked position.

[0231] Further, see Figures 8 to 10 In one embodiment, the second connecting mechanism 50 further includes a sixth reset member 330, which abuts against the locking hook 510 to hold 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. In this way, when the first engaging part 2911 retracts 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 smooth unlocking and reducing the risk of the locking hook 510 locking up.

[0232] The following is combined Figure 8 , Figure 9 , Figure 28 as well as Figure 29 This will explain the locking and unlocking principle of the locking hook 510 provided according to an embodiment of the present invention.

[0233] See Figure 9 and Figure 29 When the infant carrier body 100 is not installed on the base assembly 20, the locking hook 510 is held in the unlocked position by the action of the sixth reset member 330. At the same time, the limiting member 291 is in the sixth position, and the first mating part 2911 is disengaged from the locking recess 513.

[0234] See also Figure 9 and Figure 29 When the infant carrier body 100 needs to be installed onto the base assembly 20, that is, when the front locking member 101 needs to be connected to the second connecting mechanism 50, the user can first place the front locking member 101 into the limiting groove 520 and make the front locking member 101 abut against the pushing wall surface 5112. Then, push the front locking member 101 downward to drive the locking hook 510 to rotate clockwise around the pivot axis 530 until the pushing wall surface 5112 retracts from the limiting groove 520, and the locking wall surface 5111 extends into the limiting groove 520 to seal the opening of the limiting groove 520. At the same time, after the locking hook 510 rotates, the locking recess 513 is opposite to the first mating part 2911. The fifth reset member 292 drives the first mating part 2911 to move and extend into the locking recess 513, finally keeping the locking hook 510 in the locked position, realizing a stable connection with the front locking member 101.

[0235] See Figure 8 and Figure 28 When it is necessary to separate the infant carrier body 100 from the base assembly 20, that is, when it is necessary to disengage the front engaging member 101 from the second connecting mechanism 50, the user can move the limiting member 291 from the fifth position to the sixth position. During this process, the first engaging part 2911 gradually retracts from the locking recess 513. When the first engaging part 2911 is completely retracted from the locking recess 513, the engaging hook 510 automatically rotates counterclockwise around the pivot axis 530 under the action of the sixth reset member 330, and the locking wall surface 5111 retracts from the limiting groove 520, so that the opening of the limiting groove 520 is opened.

[0236] In one embodiment, such as Figure 29 and Figure 30As shown, the receiving groove 511 is provided with a push protrusion 512, which is disposed on the push wall 5112 and located on the movement path of the front engaging member 101 on the push wall 5112. The push protrusion 512 is adapted to be pushed by the front engaging member 101 so that the engaging hook 510 can pivot to the locked position. Specifically, when it is necessary to switch the engaging hook 510 from the unlocked position to the locked position, the user can push the push wall 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 5112 towards the bottom of the U-shaped receiving groove 511. At the same time, the locking recess 513 on the engaging hook 510 gradually approaches the first mating part 2911 of the limiting member 291. Since the push protrusion 512 is provided 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 pivot further, so that when the front engaging member 101 moves to the bottom of the receiving groove 511, the first mating part 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 mating part 2911. When the current engaging member 101 is at the top of the pushing protrusion 512, the middle of the locking recess 513 is directly opposite the first mating part 2911, allowing the first mating part 2911 to be inserted into the bottom of the locking recess 513 without contacting its sidewall. When the current engaging member 101 crosses the top of the pushing protrusion 512 and reaches the engaged position, the locking recess 513 pivots relative to the first mating part 2911, and one sidewall of the locking recess 513 abuts against the first mating part 2911, so that the locking recess 513 and the first mating part 2911 are tightly engaged. More specifically, when the engaging hook 510 is in the locked position, the pushing protrusion 512 and the front engaging member 101 are in an interference fit.

[0237] To facilitate user operation of the limiting member 291 to place the locking hook 510 in the unlocked position, in one embodiment, such as Figure 8 and Figure 9 As shown, the base assembly 20 also includes a second release mechanism 310. The second release mechanism 310 is operably connected to the limiting member 291 and is used to drive the limiting member 291 to move from the fifth position to the sixth position. In this way, the user can switch the limiting member 291 from the fifth position to the sixth position by operating the second release mechanism 310.

[0238] See Figure 8 and Figure 9In one embodiment, the second release mechanism 310 includes a second operating member 311 and a second traction 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 traction 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 which time the first engaging portion 2911 of the limiting member 291 extends into the locking recess of the engaging hook 510, so that the engaging hook 510 is held 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 which time the first engaging portion 2911 of the limiting member 291 disengages from the locking recess of the engaging hook 510, so that the engaging hook 510 can be switched to the release position.

[0239] See also Figure 8 and Figure 9 Specifically, in this embodiment, the second traction assembly 312 includes a second traction rope 3121 and a second traction sleeve 3122 movably sleeved 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 limiting member 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 part 3113 (see...). Figure 23 and Figure 31 The second fixing part 3113 is used to connect the second sleeve end 31222 of the second traction sleeve 3122. When the second operating member 311 switches from the seventh position to the eighth position, the second traction sleeve 3122 deforms so that the second traction rope 3121 pulls the limiting member 291 to switch from the fifth position to the sixth position.

[0240] It should be noted that the second traction sleeve 3122 and the first traction sleeve 2442 are both flexible cable sleeves.

[0241] See Figure 8 , Figure 9 and Figure 23In this embodiment, the base assembly 20 is generally T-shaped. The limiting member 291 slides within 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 within the base assembly 20 so that the first rope end 31211 is connected to the limiting member 291, and 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 along the left-right direction (second direction F2) on the horizontal portion of the T-shaped base assembly 20. When the limiting member 291 needs to be switched from the fifth position to the sixth position, the second operating member 311 is pushed towards the inside of the base assembly 20 along the second direction F2. 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 with the second traction sleeve 3122. Since the second 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 shortens, causing the first rope end 31211 to move closer to the first sleeve end 31221 (i.e., the first rope end 31211 moves forward in the front-back direction). In other words, when the second operating member 311 is pushed towards the inside 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...). Figure 23 Meanwhile, under the transmission action of the second traction sleeve 3122, the length L1 of the section of the second traction rope 3121 between the first rope end 31211 and the first sleeve end 31221 decreases (see...). Figure 8 and Figure 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.

[0242] See Figure 5 Typically, when the infant carrier body 100 is connected to the base assembly 20 via the second connecting mechanism 50, the gap between the infant carrier body 100 and the base assembly 20 is small. In this embodiment, the ease of unlocking is improved by using an inward pushing method for the second operating member 311. In other words, by using an inward pushing method for the second operating member 311, the problem of inconvenient unlocking due to the small gap between the infant carrier body 100 and the base assembly 20 after installation can be solved. Specifically, in this embodiment, see the figure. Figure 5 , Figure 22 as well as Figure 31The second operating member 311 has a pushing part 3112. The pushing part 3112 protrudes from the sliding plane of the second operating member 311 on the base assembly 20. When operating the second operating member 311, the pushing part 3112 can be pushed by the finger.

[0243] Of course, in other embodiments, the second traction assembly 312 may only include the second traction rope 3121. The first end 31211 of the second traction rope 3121 is connected to the limiting member 291, and the second end of the second traction rope 3121 is connected to the second operating member 311. In this case, when it is necessary to switch the limiting member 291 from the fifth position to the sixth position, the second operating member 311 can be pulled outward along the second direction F2 towards the base assembly 20, causing the limiting member 291 to rotate so that the first mating part 2911 disengages from the locking recess 513.

[0244] See Figure 6 , Figure 8 as well as Figure 23 In one embodiment, the second release mechanism 310 further includes a fourth reset member 320. The fourth reset member 320 provides an elastic restoring force to the second operating member 311 to hold the second operating member 311 in the seventh position.

[0245] In one embodiment, such as Figure 6 As shown, the base assembly 20 has a release indicator area 340. The release indicator area 340 indicates whether the first locking member 230 is in the locked or unlocked position based on the relative position of the second operating member 311 and the base assembly 200. This release indicator area 340 is, for example, two colored blocks located on the base assembly 20 (e.g., one is green and the other is red). The second operating member 311 is provided with an observation hole 3111 for observing the release indicator area 340 (see...). Figure 7 , Figure 32 When the second operating member 311 slides on the base assembly 20, the observation hole 3111 can switch between two color blocks. Therefore, the user can determine whether the first locking member 230 is in the locked or unlocked position by the color displayed in the observation hole 3111. More specifically, in this embodiment, when the first locking member 230 is in the locked position, the color block displayed in the observation hole 3111 is green; when the first locking member 230 is in the unlocked position, the color block displayed in the observation hole 3111 is red. More specifically, the red color block is closer to the outer side of the base assembly 20 than the green color block.

[0246] See Figure 8 and Figure 9In one embodiment, the second connecting mechanism 50 includes two engaging hooks 510, which are spaced apart along the extending direction of the limiting groove 520. Specifically, the limiting groove 520 extends along a first direction F1. The locking and retaining mechanism 290 includes two limiting members 291 corresponding to the two engaging hooks 510 respectively. Each limiting member 291 is pivotally connected to the base assembly 20, and the two limiting members 291 are pivotally connected to each other. Specifically, the two limiting members 291 are pivotally connected around a second pivot point Q2. Correspondingly, the base assembly 20 is provided with two second operating members 311 and two second traction assemblies 312. The two second operating members 311 are slidably disposed at both ends of the horizontal portion of the T-shaped base assembly 20, and the second traction assemblies 312 are connected between the corresponding second operating members 311 and the corresponding limiting members 291. Therefore, when one of the limiting members 291 switches between the fifth position and the sixth position, the other limiting member 291 will switch between the fifth position and the sixth position simultaneously; in other words, when one of the limiting members 291 switches from the fifth position to the sixth position, the other limiting member 291 will switch from the fifth position to the sixth position simultaneously.

[0247] See Figures 55 to 59 Another embodiment of this utility model provides a second connecting mechanism 50. The second connecting mechanism 50 includes a locking hook 510 and a limiting groove 520 disposed on the base assembly 20. Specifically, the structure and position of the limiting groove 520 in this embodiment are the same as in the previous embodiment, and the position of the locking hook 510 in this embodiment is the same as in the previous embodiment, the only difference being a slight difference in the structure of the locking hook 510. Unless otherwise specified, the structure of the locking hook 510 and its connection relationship with other components in this embodiment can be found in the embodiments shown above, and will not be repeated here. The following mainly describes the differences between this embodiment and the above embodiments (i.e., the related embodiments concerning the second connecting mechanism 50).

[0248] See Figure 55 and Figure 56 In another embodiment, the engaging hook 510 is provided with a locking protrusion 514, omitting the locking recess 513 in the above embodiment. Correspondingly, in this embodiment, the base assembly 20 is provided with another locking and retaining mechanism 290, which is movably disposed in the receiving cavity 203 and is used to cooperate with the locking recess 513 to keep the engaging hook 510 in the locked position.

[0249] See also Figure 57The locking and retaining mechanism 290 includes a locking hook 293 and a ninth reset member 294. The locking hook 293 has a hook portion 2931 and is rotatably disposed within the receiving cavity 203, allowing the locking hook 293 to have 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 locked position, the hook portion 2931 is located on the rotation path of the engaging hook 510 and engages 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 to the locking hook 293, so that the locking hook 293 is held in the ninth position. More specifically, the ninth reset member 294 is located at the 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.

[0250] See Figure 55 and Figure 56 In another embodiment, the cavity wall (second lower shell 202B) of the accommodating cavity 203 is provided with a relief groove 2022, and the relief groove 2022 is located on the rotation path of the hook 2931. The relief groove 2022 can increase the rotation stroke of the locking hook 293, ensuring that the locking hook 293 can enter the relief groove 2022 during rotation to completely separate the hook 2931 from the locking protrusion 514, thereby releasing the restriction on the locking hook 510. Of course, in other embodiments, the relief groove 2022 can be omitted.

[0251] See also Figure 55 and Figure 56 The bottom of the locking protrusion 514 is provided with a pushing slope 5141. The pushing slope 5141 is adapted to abut against the hook portion 2931 so that the engaging hook 510 can pivot to the locking position. Specifically, after the user places the front engaging member 101 into the limiting groove 520, he will push down the pushing wall surface 5112 of the engaging hook 510. During the downward pressing process, the engaging hook 510 pivots so that the apex B1 of the locking protrusion 514 rotates to abut against the hook portion 2931 of the locking hook 293. When the apex B1 crosses the hook portion 2931, the hook portion 2931 directly contacts the pushing slope 5141. During this process, as the ninth reset member 294 continuously provides restoring force to the locking hook 293, the hook portion 2931 of the locking hook 293 tends to move upward. Therefore, after the hook portion 2931 contacts the pushing inclined surface 5141, the hook portion 2931 can move upward along the pushing inclined surface 5141 and push against the pushing inclined surface 5141 to make the locking hook 510 continue to pivot, so that the locking wall surface 5111 of the locking hook 510 is fully inserted into the limiting groove 520.

[0252] like Figure 57 and Figure 58As shown, in another embodiment, to facilitate user operation of the locking hook 293, the locking retaining mechanism 290 further includes an operating lever 295 and an operating handle 296. The operating lever 295 is installed within the receiving cavity 203 and connected to the locking hook 293. The end of the operating lever 295 passes through the base assembly 20 (e.g., the second base 202) and is connected to the operating handle 296. The operating handle 296 can be operated to switch the locking hook 293 from the ninth position to the tenth position. Specifically, the locking hook 293 is fixedly mounted on the operating lever 295; therefore, when the operating handle 296 is rotated, the operating lever 295 rotates accordingly, thereby allowing the locking hook 293 to rotate to switch between the ninth and tenth positions. More specifically, as... Figures 55 to 59 As shown, the user can rotate the operating handle 296 clockwise. This causes the operating lever 295 to rotate the locking hook 293 clockwise, allowing the hook portion 2931 to move approximately downwards, thereby disengaging it from the pivoting path of the engaging hook 510 (e.g., the locking protrusion 514). In this embodiment, the operating handle 296 is fixedly connected to the operating lever 295. For example, the operating handle 296 is engaged with the operating lever 295; alternatively, the operating handle 296 can also be fixedly connected to the operating lever 295 via a screw or other connecting member 730. Specifically, as... Figure 54 As shown, the operating handle 296 has an arc-shaped groove 2961 on the side facing the base assembly 20, and the end of the operating lever 295 has a locking part 2951. The locking part 2951 is set at an angle to the main body of the operating lever 295. The locking part 2951 is used to insert into the arc-shaped groove 2961 so that the operating lever 295 can rotate together with the operating handle 296.

[0253] like Figure 57 and Figure 58 As shown, the second connecting mechanism 50 includes two engaging hooks 510, which are spaced apart along the extending direction of the limiting groove 520. Correspondingly, the locking and retaining mechanism 290 includes two locking hooks 293 corresponding to the two engaging hooks 510, and both locking hooks 293 are mounted on the operating lever 295. Operating handles 296 are connected to both ends of the operating lever 295. Thus, when one of the operating handles 296 is rotated, the two locking hooks 293 can be controlled to rotate simultaneously under the linkage of the operating lever 295, thereby simultaneously unlocking the two engaging hooks 510.

[0254] In the connection structure and infant carrier having the connection structure according to the embodiments of the present invention, 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 latching member on the infant carrier body, when it is necessary to install the infant carrier body onto the car seat, the infant carrier body can be directly connected to the base assembly via the second connection mechanism first, and then the base assembly can be connected to the car seat via the first connection mechanism; or, the base assembly can be connected to the car seat via the first connection mechanism first, and then the infant carrier body can be connected to the base assembly via the second connection mechanism to achieve the connection between the infant carrier body and the car seat. Furthermore, when it is necessary to carry the infant carrier body separately, the infant carrier body can be directly detached from the base assembly without carrying the entire connection structure, thus effectively reducing the burden on the user when carrying the infant carrier body.

[0255] The technical features of the above embodiments can be combined in any way. For the sake of brevity, 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.

[0256] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
