Description

[0001] This utility model is a divisional application of Chinese patent application filed on May 13, 2024, with application number 2024210361363 and invention title "Adjustment Mechanism, Adjustment Device for Baby Carrier and Baby Carrier". Technical Field

[0002] This utility model relates to the field of children's products technology, and in particular to an adjustment mechanism and an infant carrier. Background Technology

[0003] Infant vehicles, such as infant car seats and car carriers, generally consist of a seat and a backrest. To improve the comfort of infants and toddlers, the backrest is usually pivotable relative to the seat, allowing the angle between the two to be adjusted as needed, so that the infant or toddler can sit or lie down in the vehicle. However, currently common infant vehicles cannot meet the different riding posture needs of infants and toddlers of different ages, such as sitting, reclining, and lying flat, thus reducing the comfort of infants and toddlers and hindering the promotion of infant vehicles. Although some infant vehicles on the market (such as car seats) have adjustable tilt angles between the backrest and seat, the internal angle adjustment mechanism is relatively complex, prone to jamming during adjustment, and inconvenient to operate, resulting in poor stability of the infant vehicle's angle adjustment. Furthermore, too many parts can lead to excessive weight, affecting the user experience. Utility Model Content

For example, Figure 1 and 3 The first use configuration of the backrest 200 and the housing 110 is suitable for infants and young children lying down. Figure 4 and Figure 5 The second usage state of the backrest 200 and housing 110 is suitable for an infant sitting upright. It should be understood that the angle positions of the backrest 200 and housing 110 can be set to more or fewer than two as needed, and this invention does not impose any limitations on this. Furthermore, it should be understood that the correspondence between the first and second usage states of the backrest 200 and housing 110 and the posture of the infant on the infant carrier 1000 is merely exemplary and does not necessarily correspond to the infant's lying or sitting states, respectively. For example, the first usage state can also be suitable for the infant sitting upright, and the second usage state can also be suitable for the infant lying down, etc., and this invention does not impose any limitations on this.

[0119] In some embodiments, when the backrest 200 of the infant carrier 1000 is adjusted relative to the housing 110 to a supine position suitable for the infant, the angle between the backrest and the horizontal direction is greater than the angle between the leg rest and the horizontal direction, so that the infant's legs will not be higher than the head when lying flat, thus improving the comfort of the infant lying flat.

[0120] The seat section 100 has a locking member 800 on the side opposite to the seating space 300. This locking member 800 is mainly used to engage with the vehicle base on the car seat so that the infant carrier can be stably fixed to the car seat. Specifically, the locking member 800 is a rod-shaped structure, which is fixedly connected to the bottom of the seat section 100 by fasteners (screws or bolts, etc.) or directly integrally formed into the bottom of the seat section 100.

[0121] To make it easier for users to move baby carriers, in some examples, such as Figure 1 and Figure 3 As shown, the infant carrier also includes a handle 7000, which is connected to the seat portion 100 or the backrest portion 200. Optionally, the handle 7000 is detachably or non-detachably mounted to the seat portion 100 or the backrest portion 200. In this first embodiment, the housing 110 is provided with a handle connecting portion 102 (see...). Figure 6 The handle 7000 is detachably pivotally connected to the handle joint 102 of the seat 100. Thus, when the infant carrier needs to be moved, the handle 7000 can be rotated away from the seat 100 or backrest 200 for easier gripping; when the infant carrier does not need to be moved, the handle 7000 can be rotated closer to the seat 100 or backrest 200 to prevent the handle 7000 from obstructing the infant's view, while also facilitating the user to place or remove the infant from the infant carrier.

[0122] In this first embodiment, the seat portion 100 may also be pivotally connected to the backrest portion 200. In other embodiments, the seat portion 100 and the backrest portion 200 may also be fixedly connected, meaning that the seat portion 100 and the backrest portion 200 cannot move relative to each other. Specifically, in this first embodiment, one end of the seat portion 100 is pivotally connected to one end of the backrest portion 200, which means that the angle between them can be adjusted, thus allowing the infant carrier to have at least two usage states. For example... Figure 1 and Figure 3 The first usage position shown (in which the infant is lying down in the infant carrier) or Figure 4 and Figure 5The second usage state is shown (in which the infant is sitting in the carrier). Of course, at least one transition state can be provided between the first and second usage states. In this way, the user can adaptively adjust the angle between the seat 100 and the backrest 200 according to the infant's state (e.g., sleeping or awake), thereby improving the comfort of the infant in the carrier.

[0123] See Figures 4 to 7 In some examples, the backrest 200 and the seat 100 are pivotally connected via the pivot structure 400. Specifically, the front end of the backrest 200 and the rear end of the seat 100 are pivotally connected via the pivot structure 400. More specifically, the pivot structure 400 includes a first pivot engagement portion, a second pivot engagement portion, and a connecting member. The first pivot engagement portion is provided on one of the seat 100 and the backrest 200, and the second pivot engagement portion is provided on the other. The seat 100 and the backrest 200 are pivotally connected via the first and second pivot engagement portions. The connecting member pivotally connects the first and second pivot engagement portions.

[0124] Specifically, the first pivoting engagement portion includes a pivot member 420, and the second pivoting engagement portion includes a pivot seat 430. The pivot seat 430 is provided with a first engaging groove 431. The engaging connector includes a pivot cover 440, which is provided with a second engaging groove 441. The first engaging groove 431 and the second engaging groove 441 surround each other to form a pivot groove 410. At least a portion of the pivot member 420 is inserted into the pivot groove 410 and can rotate within the pivot groove 410, so that the infant carrier 1000 can switch between a first use state and a second use state. In this first embodiment, as... Figure 6 and Figure 7 As shown, the pivot seat 430 is provided in the backrest portion 200, and the pivot member 420 is provided in the seat portion 100.

[0125] It should be noted that, as used herein, "front end" refers to the end of the seat 100 away from the backrest 200, and "rear end" refers to the end of the backrest 200 away from the seat 100. More specifically, "front end" refers to the end of the infant carrier closer to the infant's feet, and "rear end" refers to the end closer to the infant's head. Furthermore, unless otherwise explicitly specified and limited, the "front," "rear," "left," and "right" orientations of the infant carrier (i.e., the infant carrier 1000) in various embodiments of this utility model can be represented by arrows F, B, L, and R in the figures. 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.

[0126] See Figures 6 to 10Specifically, the pivot cover 440 is detachably mounted on the pivot seat 430. For example, the pivot cover 440 is mounted on the pivot seat 430 by a snap-fit ​​connection; or, the pivot cover 440 is mounted on the pivot seat 430 by a threaded connection. Specifically, in this first embodiment, as... Figure 6 and Figure 8 As shown, the pivot seat 430 is provided with a first connecting hole 432, and the pivot cover 440 is provided with a second connecting hole 442. The pivot cover 440 and the pivot seat 430 are connected by fasteners such as connecting screws passing through the second connecting hole 442 and the first connecting hole 432 in sequence.

[0127] See Figures 6 to 9 In some examples, both the first engaging groove 431 and the second engaging groove 441 are arc-shaped grooves. For example... Figure 6 and Figure 10 As shown, the pivot member 420 has an arc-shaped surface 421, the curvature of which matches the curvature of the pivot groove 410 wall. This improves the smoothness of the pivot member 420's rotation within the pivot groove 410. Specifically, in this first embodiment, both the first engaging groove 431 and the second engaging groove 441 are semi-circular grooves, so that a circular pivot groove 410 can be formed when they are closed together. Of course, in other alternative embodiments, the first engaging groove 431 and the second engaging groove 441 can be other arc-shaped grooves, as long as the first engaging groove 431 and the second engaging groove 441 can form a complete circular pivot groove 410. For example, when the first engaging groove 431 is a 2 / 3 circular arc groove, the second engaging groove 441 is a 1 / 3 circular arc groove.

[0128] In some examples, one of the pivot seat 430 and the pivot member 420 is integrally formed on the seat portion 100, and the other is integrally formed on the backrest portion 200. In other words, when the pivot seat 430 is integrally formed on the seat portion 100, the pivot member 420 is integrally formed on the backrest portion 200; and when the pivot seat 430 is integrally formed on the backrest portion 200, the pivot member 420 is integrally formed on the seat portion 100. Specifically, according to the foregoing, in this first embodiment, as... Figure 8 and Figure 10As shown, the pivot seat 430 is integrally formed on the backrest portion 200, and the pivot member 420 is integrally formed on the seat portion 100. This improves the structural strength of the pivot structure 400, thereby enhancing the reliability of the pivot. Of course, in some alternative embodiments, one of the pivot seat 430 and the pivot member 420 is detachably connected to the seat portion 100, and the other is detachably connected to the backrest portion 200. By integrally forming the pivot structure 400 with the seat portion 100 and the backrest portion 200, a pivot connection between the backrest and the seat is achieved, eliminating the need for separate pivot shafts and pivot holes. This reduces the number of parts, simplifies the reclining function, makes adjustment more stable and reliable, and reduces the overall weight of the infant carrier.

[0129] In this first embodiment, the pivot seat 430 is located at one end of the backrest portion 200 near the seat portion 100, that is, at the front end of the backrest portion 200. The pivot member 420 is located at one end of the seat portion 100 near the backrest portion 200, that is, at the rear end of the seat portion 100.

[0130] Specifically, the pivot seat 430 includes through portions 433 formed on both sides of the first engaging groove 431, and the aforementioned first connecting hole 432 has two portions 433 respectively disposed on the two through portions 433. In this first embodiment, a bracket 120 is formed on the seat portion 100. The bracket 120 includes a bracket body 121, a bracket bottom wall 122, and two bracket side walls 123. The bracket body 121 is connected to the bracket bottom wall 122 at an angle, and the two bracket side walls 123 are connected to both sides of the bracket body 121 and the bracket bottom wall 122 and are disposed opposite to each other. A pivot member 420 is connected between the two bracket side walls 123. A through hole 130 is defined between the pivot member 420, the bracket body 121, the bracket bottom wall 122, and the two bracket side walls 123. The through portions 433 are adapted to be received in the through hole 130 for forming a connection between the backrest portion 200 and the seat portion 100.

[0131] See Figure 8 and Figure 10 In this first embodiment, the infant carrier is provided with two sets of the aforementioned pivoting structures 400, which are spaced apart along the left-right direction of the infant carrier. This improves the stability of the backrest 200 pivoting relative to the seat 100. Of course, one or more sets of the aforementioned pivoting structures 400 may be provided as needed, and this invention is not limited thereto.

[0132] Please see Figures 11 to 14An adjustment mechanism 500 is disposed between the seat portion 100 and the backrest portion 200 to adjust the included angle between the seat portion 100 and the backrest portion 200 and to maintain the included angle between them. Specifically, the adjustment mechanism 500 includes a locking member 510, a locking member 520, and a first operating member 530. The locking member 510 is mounted on one of the seat portion 100 and the backrest portion 200, and the locking member 510 is provided with a locking recess 511. In this first embodiment, the locking member 520 is a locking pin. The locking member 520 is mounted on the other of the seat portion 100 and the backrest portion 200. The locking member 520 can engage and disengage with the locking recess 511 to lock and unlock the backrest portion 200 to the seat portion 100. In this first embodiment, the moving direction of the locking member 520 is perpendicular to the lateral width direction of the seat portion 100 or the backrest portion 200. The locking member 520 moves in a direction perpendicular to the lateral width direction of the seat portion 100 or the backrest portion 200 to lock and unlock the seat portion 100 and the backrest portion 200, making the setting of the moving stroke and path of the locking member 520 more flexible. Specifically, the locking member 510 has a sheet-like structure and the plane on which the locking member 510 is located is perpendicular to the lateral width direction of the seat portion 100 or the backrest portion 200. The locking recess 511 and the sliding recess 512 are both provided on the sheet-like locking member, so the plane on which the locking recess 511 and the sliding recess 512 are located is also perpendicular to the lateral width direction of the seat portion 100 or the backrest portion 200.

[0133] The first operating member 530 is movably mounted on either the seat portion 100 or the backrest portion 200, and has a locked position and an unlocked position along its movement path. The first operating member 530 is operably connected to the locking member 520 to drive the locking member 520 to move on the locking member 510. Specifically, when the first operating member 530 is in the locked position, the locking member 520 is located within the locking recess 511, and the backrest portion 200 is fixed relative to the seat portion 100, meaning that the backrest portion 200 cannot rotate relative to the seat portion 100, thereby allowing the infant carrier to remain in a specific use state, such as a first use state or a second use state. When the first operating member 530 is in the unlocked position, the locking member 520 retracts from the locking recess 511, and the backrest portion 200 can pivot relative to the seat portion 100, meaning that the angle between the backrest portion 200 and the seat portion 100 can be adjusted. Meanwhile, the locking member 510, located on the seat portion 100, effectively strengthens the adjustment mechanism 500. Since the adjustment mechanism 500 of the backrest portion 200 and seat portion 100 experiences significant force during a collision, strengthening the adjustment mechanism 500 with the locking member 510 helps prevent deformation of the infant carrier upon impact. In this first embodiment, the locking member 510 is installed on the seat portion 100, but it can also be integrally formed on the seat portion 100, as long as it serves to strengthen the structural strength at that location. Furthermore, the locking member 510 is located at the upper edge of the seat portion 100 or backrest portion 200, as far away from the pivot structure 400 as possible. This arrangement disperses the force distribution across the entire infant carrier, resulting in more even force distribution, avoiding stress concentration, and ensuring the impact performance of the infant carrier during impact.

[0134] The structure and working principle of the aforementioned adjustment mechanism 500 are relatively simple. By controlling the position of the first operating member 530, the locking member 520 can enter or exit the locking recess 511, thereby adjusting the angle between the seat part 100 and the backrest part 200. This process is convenient to operate and is not prone to jamming, which can effectively improve the stability of angle adjustment.

[0135] See Figures 13 to 15 In some examples, the locking recess 511 includes at least two locking grooves 5111. The locking member 510 also has a sliding recess 512, which connects to each locking groove 5111, and the groove wall of the sliding recess 512 and the groove wall of each locking groove 5111 form a closed structure. The locking member 520 is movably disposed within the sliding recess 512 and each locking groove 5111. When the first operating member 530 is in the locked position (see...), Figure 11 and Figure 13At this time, the locking member 520 is located in one of the locking slots 5111, and the backrest 200 is fixed relative to the seat 100. When the locking member 520 is successively located in each locking slot 5111, the angle between the backrest 200 and the seat 100 is different, which is equivalent to the infant carrier presenting different backrest angle states. When the first operating member 530 is in the unlocked position (see...), Figure 14 At this time, the locking member 520 is located in the sliding recess 512, and the backrest 200 can pivot relative to the seat 100.

[0136] Specifically, in this first embodiment, as Figure 15 As shown, one locking groove 5111 is referred to as the first locking groove 5111A, and the other locking groove 5111 is referred to as the second locking groove 5111B. The sliding recess 512 connects the first locking groove 5111A and the second locking groove 5111B. Thus, the locking member 520 is considered to be movably inserted into the sliding recess 512, the first locking groove 5111A, and the second locking groove 5111B. Specifically, when the first operating member 530 is in the locked position, the locking member 520 can be located in either the first locking groove 5111A or the second locking groove 5111B. More specifically, when the locking member 520 is located in the first locking groove 5111A, the seat portion 100 and the backrest portion 200 are at a first angle, and the infant carrier 1000 is in a first use state. When the locking member 520 is located within the second locking groove 5111B, the seat portion 100 and the backrest portion 200 are at a second angle, and the first angle is greater than the second angle, thus the infant carrier 1000 is in a second usage state. In this first embodiment, as... Figure 11 and Figure 13 As shown, when the locking member 520 is located in the first locking groove 5111A, the infant carrier is in the first use state. At this time, the angle between the backrest 200 and the seat 100 is called the first angle. When the locking member 520 is located in the second locking groove 5111B, the infant carrier is in the first use state. At this time, the angle between the backrest 200 and the seat 100 is called the second angle. The first angle is greater than the second angle.

[0137] See Figures 13 to 15In some examples, when the number of locking slots 5111 is greater than three, the locking slots 5111 other than the first locking slot A and the second locking slot B can be considered as transition slots 5111C. These transition slots 5111C are located between the first locking slot A and the second locking slot B and are connected to the sliding recesses 512. For example, in this first embodiment, there are three locking slots 5111, including the first locking slot A, the second locking slot B, and the transition slot C, which is located between the first locking slot A and the second locking slot B. In other embodiments, the locking slots 5111 may also be, for example, four, including the first locking slot A, the second locking slot B, and two transition slots 5111C. Both transition slots 5111C are located between the first locking slot A and the second locking slot B. When the locking member 520 is located within the transition groove 5111C, the seat portion 100 and the backrest portion 200 are at a third angle, which is greater than the second angle and less than the first angle. The infant carrier is in a transitional state between a first and second use state; that is, when the infant carrier is in this transitional state, the angle between the backrest portion 200 and the seat portion 100 is between the first and second angles. Specifically, the more transition grooves 5111C there are, the smaller the adjustment interval of the angle between the backrest portion 200 and the seat portion 100, allowing the user to more precisely adjust the angle between the backrest portion 200 and the seat portion 100, making the infant carrier's position more suitable for the infant's seating needs and providing greater comfort.

[0138] See Figure 7 as well as Figures 13 to 15 The sliding recess 512 is located above the first locking groove 5111A, the second locking groove 5111B, and the transition groove 5111C. That is, the locking recess 511 is closer to the pivot structure 400 (or the axis of rotation X1-X1 between the seat part 100 and the backrest part 200) than the sliding recess 512. When it is necessary to adjust the included angle between the seat part 100 and the backrest part 200, the locking member 520 needs to be moved upward along the first locking groove 5111A, the second locking groove 5111B, or the transition groove 5111C into the locking recess 511. When it is necessary to lock the included angle between the seat part 100 and the backrest part 200, the locking member 520 needs to be moved downward from the locking recess 511 into the first locking groove 5111A, the second locking groove 5111B, or the transition groove 5111C.

[0139] In some examples, the locking slots 5111 (i.e., the first locking slot 5111A, the second locking slot 5111B, and the transition slot 5111C) are spaced apart circumferentially around the rotation axis X1-X1 between the seat portion 100 and the backrest portion 200. It should be noted that this rotation axis X1-X1 is the same rotation axis on which the pivot member 420 pivots within the pivot slot 410. The sliding recess 512 has an arc-shaped structure, and the center of the arc of the sliding recess 512 is located on the rotation axis X1-X1. Thus, when the locking member 520 exits from the first locking slot 5111A, the second locking slot 5111B, or the transition slot 5111C into the sliding recess 512, the locking member 520 can be moved within the sliding recess 512 by rotating the backrest portion 200.

[0140] In this first embodiment, as Figure 15 As shown, since the arc of the sliding recess 512 is relatively short, the sliding recess 512 will be approximately straight. In other embodiments, the sliding recess 512 can also be set to be straight, as long as the sliding of the locking member 520 in the sliding recess 512 is not blocked by the respective locking grooves 5111A, 5111C, and 5111B.

[0141] In some examples, the first actuating element 530 may be directly operably connected to the locking element 520. Of course, in other alternative embodiments, the first actuating element 530 may be indirectly operably connected to the locking element 520. For example, as... Figure 13 and Figure 14 As shown, the adjusting mechanism 500 may further include a sliding transmission member 540, through which the first operating member 530 is operably connected to the locking member 520. Specifically, the sliding transmission member 540 is provided with a connecting portion 541 and a transmission portion 542. The locking member 520 is provided in the connecting portion 541, and the transmission portion 542 is provided with a guide groove 543, which extends obliquely relative to the moving direction (first direction F1) of the first operating member 530. More specifically, in this first embodiment, as... Figures 11 to 14As shown, the locking member 510 is mounted on the seat portion 100. The first operating member 530 is movably mounted on the backrest portion 200 and has a driving part 531. The driving part 531 can slide within the guide groove 543 to drive the sliding transmission member 540 to move the locking member 520 relative to the locking member 510 along the second direction F2, so that the locking member 520 switches between the sliding recess 512 and the locking recess 511. It should be noted that in this first embodiment, the moving direction of the first operating member 530 (i.e., the first direction F1) is the same as the extending direction of the backrest portion 200 in the front-rear direction, and the first direction F1 is perpendicular to the lateral width direction of the seat portion 100 or the backrest portion 200. The moving directions of the sliding transmission member 540 and the locking member 520 (i.e., the second direction F2) are perpendicular to both the first direction F1 and the lateral width direction of the seat portion 100 or the backrest portion 200. In most existing infant carriers, the locking element 520 moves in the lateral direction of the seat portion 100 or the backrest portion 200 to lock and unlock the seat portion 100 and the backrest portion 200. However, in this first embodiment, the locking element 520 moves in a direction perpendicular to the lateral direction of the seat portion 100 or the backrest portion 200 to lock and unlock the seat portion 100 and the backrest portion 200, making the setting of the movement stroke and path of the locking element 520 more flexible.

[0142] See Figure 11 and Figure 16 In some examples, the drive unit 531 includes a pin 5311 and a pull block 5312. The pull block 5312 has a U-shaped structure and a first holding cavity 5313, which is used to hold the transmission part 542 of the sliding transmission member 540. The pin 5311 passes through one side wall of the first holding cavity 5313 and the guide groove 543 in sequence, and then connects to the other side wall of the first holding cavity 5313. In this way, the pin 5311 is less likely to disengage from the guide groove 543 when sliding in the guide groove 543, thereby improving the stability of the drive connection between the first operating member 530 and the sliding transmission member 540.

[0143] See Figure 2 , Figure 13 as well as Figure 14 In some examples, the first operating member 530 also has an operating section 532. The operating section 532 is located on the side of the backrest 200 opposite to the seating space 300 and at the rear end of the backrest 200. The operating section 532 is exposed through the operating hole 201 of the backrest 200 for easy operation and connection to the drive section 531. In this way, the user can directly control the first operating member 530 to switch between the locked and unlocked positions through the operating section 532, thereby controlling the sliding of the drive section 531 within the guide groove 543.

[0144] See Figure 13 , Figure 14 as well as Figure 17In some examples, the guide groove 543 has a first groove end 5431 and a second groove end 5432 disposed opposite to each other. Specifically, the first groove end 5431 is closer to the locking member 510 relative to the second groove end 5432, and along the moving direction of the first operating member 530 (first direction F1), the second groove end 5432 is closer to the operating part 532 relative to the first groove end 5431. More specifically, when the first operating member 530 is in the locked position (see... Figure 13 The drive unit 531 is located at the first slot end 5431. When the first operating member 530 is in the unlocked position (see...), Figure 14 The drive unit 531 is located at the second slot end 5432. Specifically, when the user pulls the operating part 532 to move the driving part 531 from the first groove end 5431 to the second groove end 5432, the driving part 531 can drive the sliding transmission member 540 to move upward relative to the locking member 510 along the guide direction of the locking groove 5111 (first locking groove 5111A or second locking groove 5111B or transition groove 5111C), thereby driving the locking member 520 to move from the locking groove 5111 to the sliding recess 512. In this way, the locking member 520 is not restricted by the locking groove 5111, so that the locking member 520 can move in the circumferential direction along the rotation axis X1-X1 within the sliding recess 512. Therefore, when the first operating part 530 is in the unlocked position, that is, when the locking member 520 moves to the sliding recess 512, the user can adjust the state of the baby carrier by pushing the backrest 200 to rotate the backrest 200 around the rotation axis X1-X1.

[0145] See Figure 11 In some examples, when the locking member 510 is installed on the inner wall of the seat portion 100, a gap is left between it and the inner wall. The connecting portion 541 of the sliding transmission member 540 has a U-shaped structure and a second retaining cavity 544, which is used to retain the locking member 510. The locking member 520 passes through one side wall of the second retaining cavity 544, the locking recess 511 or the sliding recess 512 of the locking member 510 in sequence, and then connects to the other side wall of the second retaining cavity 544. In this way, the locking member 520 is prevented from disengaging from the locking recess 511 or the sliding recess 512 during movement, thereby improving the stability of the infant carrier angle adjustment.

[0146] In this first embodiment, as Figure 11 and Figure 12 As shown, the locking member 520 is connected to the connecting portion 541 of the sliding transmission member 540 via the latch 570. Specifically, the locking member 520 passes through a through hole 5441 on the side wall of the second holding cavity 544 (see...). Figure 17After that, it is connected to the latch 570. The size of the latch 570 (specifically the length L1) is larger than the diameter of the through hole 5441, so that the latch 570 can abut against the edge of the through hole 5441 to prevent the locking member 520 from disengaging from the through hole 5441 and the connecting part 541.

[0147] See Figure 11 and Figure 12 In some examples, the adjustment mechanism 500 may also include a mounting bracket 550. Optionally, the mounting bracket 550 is fixedly mounted to the backrest 200, or the mounting bracket 550 is detachably mounted to the backrest 200. Figure 12 and Figure 18 As shown, the mounting bracket 550 is provided with a strip-shaped groove 551, which extends from the locking recess 511 towards the sliding recess 512. Figure 12 and Figure 13 As shown, the locking member 520 passes through the strip groove 551 and the connecting portion 541 and is movably inserted into the sliding recess 512 or the locking recess 511. Furthermore, the size (specifically, the length L1) of the latch 570 is greater than the width L2 of the strip groove 551, thus preventing the locking member 520 from disengaging from the strip groove 551 during movement. When the locking member 520 moves to the sliding recess 512, the user pushes the backrest 200, causing the mounting bracket 500 to rotate together with the backrest 200 around the rotation axis X1-X1. Simultaneously, the mounting bracket 500 pushes the locking member 520 to rotate around the rotation axis X1-X1 within the locking recess 511, thereby changing the angle between the backrest 200 and the seat portion 100.

[0148] I've come to pay my respects again. Figure 11 and Figure 12 In some examples, the adjusting mechanism 500 may further include a reset member 560. This reset member 560 abuts between the mounting bracket 550 and the sliding transmission member 540, and is used to drive the sliding transmission member 540 to reset, causing the locking member 520 to move from the sliding recess 512 to the locking recess 511 (first locking groove 5111A, second locking groove 5111B, or transition groove 5111C). Specifically, the reset member 560 may be a spring or other type of elastic element. In this first embodiment, the reset member 560 is a spring. Figure 17 As shown, a third holding cavity 545 is formed on the sliding transmission member 540. (As indicated...) Figure 12 and Figure 13 As shown, the spring is housed within the third retaining cavity 545, with one end abutting against the bottom wall of the third retaining cavity 545 and the other end abutting against the mounting bracket 550. This prevents the spring from shifting during compression or reset. More specifically, the third retaining cavity 545 also contains a limiting protrusion 546, on which the spring is sleeved, further preventing the spring from shifting.

[0149] The following is combined Figure 6 , Figure 7 as well as Figures 12 to 14 This explains the process of adjusting the position of the infant carrier (the angle between the backrest 200 and the seat 100).

[0150] like Figure 13 As shown, when the locking member 520 is located in the first locking groove 5111A, the groove wall of the first locking groove 5111A can restrict the locking member 520 from moving into other locking grooves 5111, thereby restricting the backrest 200 from pivoting relative to the seat 100, and thus allowing the infant carrier to remain in a lying position.

[0151] like Figure 14 As shown, when the user needs to adjust the state of the infant carrier, that is, to switch the infant carrier from a lying position to a transitional position or to a sitting position, the user can pull the operating part 532 upward along the first direction F1, so that the operating part 532 drives the driving part 531 to move upward along the first direction F1. When the operating part 532 moves upward along the first direction F1, under the action of the guide groove 543, the driving part 531 can drive the sliding transmission member 540 and the locking member 520 to move upward relative to the locking member 510 along the second direction F2, thereby causing the locking member 520 to retract from the first locking groove 5111A into the sliding recess 512, and at the same time, the reset member 560 is compressed. When the locking member 520 moves into the sliding recess 512, it can push the backrest 200, causing the backrest 200 to rotate relative to the seat 100 about the rotation axis X1-X1. At the same time, the mounting bracket 550, while rotating with the backrest 200, pushes the locking member 520 to move about the rotation axis X1-X1 within the sliding recess 512. When the locking member 520 moves to directly above the transition groove 5111C or the second locking groove 5111B, the user can release the operating part 532. At this time, the reset member 560 resets and pushes the sliding transmission member 540 downward in the opposite direction of the second direction F2, so that the locking member 520 can enter the transition groove 5111C or the second locking groove 5111B from the sliding recess 512. Specifically, during the downward movement of the sliding transmission member 540 in the opposite direction of the second direction F2, the guide groove 543 causes the driving part 531 to move downward in the opposite direction of the first direction F1, thereby resetting the operating part 532 and placing the first operating member 530 in the locked position.

[0152] In some examples, there may be one or more adjustment mechanisms 500. Specifically, in this first embodiment, there are two adjustment mechanisms 500, which are spaced apart along the left-right direction of the infant carrier. In some examples, the first operating members 530 in each adjustment mechanism 500 are arranged side by side, and the operating parts 532 of each first operating member 530 are independent of each other. When it is necessary to adjust the state of the infant carrier, both operating parts 532 can be operated simultaneously. In this first embodiment, as... Figure 16 As shown, each of the first operating elements 530 shares a single operating unit 532, meaning that the drive units 531 of each of the first operating elements 530 are controlled through the same operating unit 532. Thus, the two drive units 531 can be controlled simultaneously through this operating unit 532, thereby simultaneously controlling the two sliding transmission members 540 and the two locking members 520.

[0153] The infant carrier and its adjustment mechanism 500 according to the first embodiment of the present invention have at least the following technical effects:

[0154] The aforementioned adjustment mechanism 500 is disposed between the seat portion 100 and the backrest portion 200 for adjusting the included angle between the two. A locking member 510 is mounted on either the seat portion 100 or the backrest portion 200, and a first operating member 530 is movably mounted on either the backrest portion 200 or the seat portion 100. Since the locking member 520 is movably disposed on the locking member 510, and the first operating member 530 is operably connected to the locking member 520, the position of the locking member 520 on the locking member 510 can be directly controlled by controlling the first operating member 530. Specifically, since the first operating member 530 has a locked position and an unlocked position on its movement path, when the first operating member 530 is in the locked position, the locking member 520 is confined within the locking recess 511 on the locking member 510, thus fixing the backrest 200 relative to the seat 100 and keeping the included angle between them constant. When the first operating member 530 moves to the unlocked position, it causes the locking member 520 to retract from the locking recess 511, allowing the backrest 200 to pivot relative to the seat 100 to adjust the included angle. The structure and working principle of the adjustment mechanism 500 described above are relatively simple. Controlling the position of the first operating member 530 allows the locking member 520 to enter or retract from the locking recess 511, thereby adjusting the included angle between the seat 100 and the backrest 200. This process is convenient to operate and less prone to jamming, effectively improving the stability of angle adjustment.

[0155] like Figures 19 to 21As shown, a second embodiment of the present invention provides an infant carrier 1000. Similar to the infant carrier of the first embodiment, the infant carrier of the second embodiment also includes a seat portion 100 and a backrest portion 200. Unlike the first embodiment, in the infant carrier of the second embodiment, the backrest portion 200 is pivotally connected to the seat portion 100 at a fixed first pivot point 101, and the infant carrier of the second embodiment further includes an adjustment mechanism disposed between the backrest portion 200 and the seat portion 100, allowing the backrest portion 200 to switch between at least two angular positions relative to the seat portion 100. In this second embodiment, to distinguish it from the first embodiment, the adjustment mechanism is referred to as an adjustment device 600. In other words, the adjustment device 600 is a variation of the adjustment mechanism 500.

[0156] Specifically, the seat portion 100 may include a housing 110 and a leg rest portion 150. The backrest portion 200 is pivotally connected to the housing 110 to form a seating space 300 for accommodating infants and toddlers. In this second embodiment, the leg rest portion 150 and the housing 110 are integrally formed.

[0157] The backrest 200 has at least two angular positions relative to the housing 110 to accommodate different seating needs of infants and toddlers. For example, Figure 19 The backrest 200 and the first angular position of the housing 110 are suitable for the sitting posture of infants and young children. Figure 20 The third angle position of the backrest 200 and the shell 110 is suitable for the reclining position of infants and young children. Figure 21 The second angular position of the backrest 200 and the housing 110 is suitable for the infant's lying posture, etc. It should be understood that the angular positions of the backrest 200 and the housing 110 can also be set to more or less three as needed, and this utility model does not limit this. In addition, it should be understood that the correspondence between the first angular position, the second angular position, and the third angular position of the backrest 200 and the housing 110 and the posture of the infant on the infant carrier 1000 is merely exemplary, and does not necessarily correspond to the infant's sitting posture, the infant's lying posture, and the infant's reclining posture, respectively. For example, the first angular position can also be suitable for the infant's lying posture, the second angular position can also be suitable for the infant's reclining posture, and the third angular position can also be suitable for the infant's sitting posture, etc., and this utility model does not limit this.

[0158] like Figures 22 to 24As shown, the housing 110 is provided with a handle connection portion 102, which is used to connect with the handle 7000 of the infant carrier 1000. With the direction facing the infant when riding in the infant carrier 1000 as "front," and the direction from the bottom edge of the housing 110 to the handle connection portion 102 as "upward," the first pivot point 101 is located in front of the handle connection portion 102, which is beneficial to the impact force performance of the infant carrier 1000. Furthermore, the first pivot point 101 is located near the bottom, which helps to lower the center of gravity of the infant riding in the infant carrier 1000, improving the safety of the infant. Figures 19 to 24 The accompanying diagrams will continue to use arrow "F" to indicate the front, arrow "B" to indicate the rear, arrow "U" to indicate the top, and arrow "D" to indicate the bottom. Arrow "F" points in the direction the infant is facing when riding in the infant vehicle 1000.

[0159] Figure 25 and Figure 26 A three-dimensional structural schematic diagram of the infant carrier 1000 in this embodiment is shown. Figure 25 The first angular position of the backrest 200 and the housing 110 of the infant carrier 1000 shown is suitable for an infant's sitting posture. Figure 26 The second angled position of the backrest 200 and housing 110 of the infant carrier 1000 shown is suitable for the infant's supine position. See also... Figure 27 The backrest 200 includes a backrest body 210, backrest side panels 220 connected to both sides of the backrest body 210, and a backrest extension 230 connected to the lower side of the backrest body 210. When the backrest 200 is pivotally connected to the housing 110, the backrest extension 230 is located on the side of the housing 110 facing the seating space. A headrest 280 for supporting the head of an infant is provided on the side of the backrest body 210 away from the backrest extension 230. The headrest 280 is slidably connected to the backrest body 210, so that the position of the headrest 280 relative to the backrest body 210 can be adjusted according to the size of the infant. Please refer to [further details omitted]. Figure 28 The shell 110 is a one-piece molded structure, generally including a shell body 112 and shell side plates 113 connected to both sides of the shell body 112. A leg rest 150 is fixed to the side of the shell body 112 away from the backrest extension 230, and is used to support the infant's legs. In this embodiment, the leg rest 150 and the shell body 112 are a one-piece molded structure.

[0160] like Figure 29 As shown, the two backrest side plates 220 of the backrest part 200 are pivotally connected to the two shell side plates 113 of the shell 110, respectively. Figure 30 for Figure 29The enlarged view at point A shows the specific pivoting structure between one of the back-side panels 220 and the corresponding shell side panel 113. At least the lower end of the back-side panel 220 is located inside the corresponding shell side panel 113. A pivot hole 221 is provided at the lower end of the back-side panel 220, and a pivot protrusion 1210 is provided on the inner side of the shell side panel 113. The pivot protrusion 1210 has a pivot groove (not shown in the figure), and a pivot shaft (not shown in the figure) passes through the pivot hole 221 and the pivot groove on the pivot protrusion 1210 to achieve the pivoting between the back-side panel 220 and the corresponding shell side panel 113. In other embodiments, the positions of the pivot hole 221 and the pivot protrusion 1210 can be interchanged. Alternatively, the back-side panel 220 and the corresponding shell side panel 113 can also be pivoted using other structures.

[0161] like Figure 31 As shown, the adjustment device 600 includes a locking mechanism 610 and an operating mechanism 620.

[0162] The locking mechanism 610 is disposed between the housing 110 and the backing portion 200. The locking mechanism 610 has a locked state that fixes the backing portion 200 at one of at least two angular positions (such as the first angular position or the second angular position) and an unlocked state that allows the backing portion 200 to switch between at least two angular positions (such as the first angular position and the second angular position).

[0163] In this embodiment, as Figure 31 As shown, the backrest side panels 220 and shell side panels 113 on both sides of the infant carrier 1000 are equipped with locking mechanisms 610 to achieve smooth adjustment of the angle position of the backrest 200. Figure 32 for Figure 31 The enlarged view at point B shows the specific structure of the locking mechanism 610 on one side. A mounting portion 710 is provided at the upper edge of the side of the housing 110 facing the seating space, and the mounting portion 710 has at least two engagement grooves 711. The at least two engagement grooves 711 include a third engagement groove 711 and a fourth engagement groove 711. The arrangement direction of the at least two engagement grooves 711 is staggered with the front-rear direction. Figures 32 to 35The locking mechanism 610 includes an actuator 611 and a locking pin 612. The actuator 611 includes an actuator body 6111 and a positioning protrusion 6112 protruding from one side of the actuator body 6111. In this embodiment, the actuator 611 is an integrally formed structure. In other embodiments, the actuator 611 can also be connected by the actuator body 6111 and the positioning protrusion 6112 by means of welding or riveting. The actuator body 6111 is generally rectangular in shape and has a first side 6111a, a second side 6111b, and a third side 6111c. The first side 6111a, the second side 6111b, and the third side 6111c are adjacent to each other. The first side 6111a of the actuator body 6111 is provided with a mounting hole 6111d, and one end of the locking pin 612 is inserted into the mounting hole 6111d. The second side surface 6111b of the actuating body 6111 has a generally rectangular mounting groove 6111e, which communicates with the mounting hole 6111d. In this embodiment, the mounting groove 6111e is a rectangular groove, and an elastic finger 6111f is connected to one side wall of the rectangular groove. One of the locking pin 612 and the elastic finger 6111f has a protrusion (not shown in the figure), and the other has a recess (not shown in the figure). When the locking pin 612 is inserted into the mounting hole 6111d, the protrusion and the recess engage, and the elastic force of the elastic finger 6111f presses and fixes the locking pin 612 into the mounting hole 6111d. In this embodiment, the elastic finger 6111f has a protrusion, and the locking pin 612 has a recess. The positioning protrusion 6112 protrudes from the third side surface 6111c of the actuating body 6111. The extending direction of the mounting hole 6111d intersects the extending direction of the positioning protrusion 6112. The portion of the locking pin 612 located outside the mounting hole 6111d forms a locking portion 6122. The locking portion 6122 can engage with one of at least two engaging grooves 711 (such as the third engaging groove 711 or the fourth engaging groove 711) to fix the backing portion 200 at a certain angle position (such as the first angle position or the second angle position).

[0164] Furthermore, the mounting portion 710 is located behind the handle joint 102. As mentioned earlier, the first pivot point 101 is located on the lower front side of the handle joint 102, meaning the first pivot point 101 and the mounting portion 710 are located on opposite sides of the handle joint 102. This creates a better load-bearing structure, which helps to disperse the impact force on the infant carrier 1000 in the event of a vehicle collision, making the infant carrier 1000 less prone to damage.

[0165] like Figure 33 and Figure 34 As shown, the operating mechanism 620 includes a second operating member 621, a traction member 622, a linkage member 623, and an operating reset member 624.

[0166] In this embodiment, the second operating member 621 is a handle, which is operably disposed on the side of the back of the main body 210 away from the back extension 230.

[0167] There are two linkage members 623, each driven and connected to the actuator 611 of the locking mechanism 610 on both sides. There are also two traction members 622, each with both ends connected to the second operating member 621 and the corresponding linkage member 623. Both linkage members 623 are movably mounted on the side of the backrest 200 facing away from the seating space. Each linkage member 623 includes an interconnected mounting bracket 6231 and a linkage part 6232.

[0168] The mounting bracket 6231 is generally rectangular in shape and extends along the longitudinal direction of the backrest 200. One end of the mounting bracket 6231 is connected to the traction member 622, and the other end is connected to the linkage member 6232. A receiving space 6231a is formed within the mounting bracket 6231, and the operating reset member 624 is accommodated in the receiving space 6231a. In this embodiment, the operating reset member 624 is a spring. One end of the operating reset member 624 is connected to or abuts against the linkage member 623, and the other end of the operating reset member 624 is connected to or abuts against the stop member 240 on the backrest 200. The operating reset member 624 is adapted to cause the linkage member 623 to drive the second operating member 621 to reset. In one embodiment, the stop member 240 is also arranged within the receiving space 6231a. The mounting bracket 6231 has a mounting base 6231b on the side near the linkage part 6232 (or near the locking mechanism 610). One end of the operation reset member 624 is fixed to the mounting base 6231b, and the other end is fixed to the stop member 240. Further, the mounting bracket 6231 or the stop member 240 is also provided with a guide member 241. The operation reset member 624 is sleeved on the guide member 241 to prevent displacement of the operation reset member 624 during biasing. The mounting bracket 6231 includes a first side portion 6231d and a second side portion 6231e disposed opposite to each other. A stop block 6231c is connected to approximately the middle of the first side portion 6231d and approximately the middle of the second side portion 6231e to prevent the operation reset member 624 from dislodging from the accommodating space 6231a.

[0169] like Figure 34As shown, the linkage part 6232 is also generally rectangular in shape. The extension direction of the linkage part 6232 is staggered with the extension direction of the mounting bracket 6231. For example, the extension direction of the linkage part 6232 and the extension direction of the mounting bracket 6231 can be set at a 45-degree angle. The linkage part 6232 is provided with a sliding groove 6233 extending along its extension direction. In other embodiments, the extension direction of the linkage part 6232 may not be staggered with the extension direction of the mounting bracket 6231, as long as the setting direction of the sliding groove 6233 is staggered with the extension direction of the mounting bracket 6231. The positioning protrusion 6112 of the actuator 611 forms a first sliding engagement part, and the sliding groove 6233 of the linkage part 623 forms a second sliding engagement part. The positioning protrusion 6112 is inserted into the sliding groove 6233 and can move along the sliding groove 6233, thereby realizing the sliding engagement of the actuator 611 and the linkage part 623.

[0170] Furthermore, combined Figure 32 and Figure 34 The locking part 6122 can move in a direction close to or away from the mounting part 710, that is, it can move in a direction close to or away from a certain engagement groove 711 (such as the third engagement groove 711 or the fourth engagement groove 711). The sliding groove 6233 is inclined to the direction of movement of the locking part 6122. Specifically, the sliding groove 6233 is inclined upward in a direction close to the mounting part 710, which in this embodiment means that the sliding groove 6233 is inclined upward in a direction from the inside to the outside.

[0171] Specifically, the backrest body 210 includes a backrest panel 211 and a cover 212 covering the side of the backrest panel 211 facing away from the seating space. The backrest panel 211 and the cover enclose an installation space. The actuator 611 and at least part of the locking pin 612 in the locking mechanism 610, and the traction member 622 and linkage member 623 in the operating mechanism 620 are all installed within this installation space, thereby making the appearance of the infant carrier neater and protecting the relevant components of the locking mechanism 610 and the operating mechanism 620 from damage.

[0172] When the second operating member 621 is pulled, the second operating member 621 can pull the linkage member 623 towards the direction closer to the second operating member 621 through the traction member 622, that is, pull the linkage member 623 upward. The linkage member 623 then drives the actuator 611 to move the locking pin 612 away from the mounting part 710 through the sliding engagement between the slide groove 6233 and the positioning protrusion 6112, that is, away from the corresponding engagement groove 711 (such as the third engagement groove 711), until the locking part 6122 of the locking pin 612 disengages from the corresponding engagement groove 711 (such as the third engagement groove 711), and the locking mechanism 610 is in the unlocked state. At this point, the backrest 200 can rotate relative to the housing 110. When the backrest 200 rotates to the desired angle position relative to the housing 110, and the locking part 6122 is aligned with another engagement groove 711 (such as the fourth engagement groove 711), the force pulling the second operating member 621 can be released. At this time, the linkage member 623 can move away from the second operating member 621 under the elastic force of the operating reset member 624, that is, move downward, so that the locking pin 612 moves towards the mounting part 710 or another engagement groove 711 (such as the fourth engagement groove 711) until the locking part 6122 of the locking pin 612 is inserted into the other engagement groove 711 (such as the fourth engagement groove 711). In this way, the backrest 200 achieves the adjustment of its angle position.

[0173] In one example, such as Figures 36 to 38 As shown, the infant carrier 1000 also includes a mounting plate 700 with a generally rectangular plate-like structure. The mounting plate 700 is fixedly connected to the housing 110, and mounting portions 710 and limiting ribs 720 are respectively provided on both sides of the mounting plate 700. Both the mounting portions 710 and the limiting ribs 720 protrude into the seating space. In this embodiment, there are two mounting plates 700, which are respectively fixedly connected to the inner sides of the two shell side plates 113 of the housing 110. The edges of the two backrest side plates 220 near the backrest extension 230, that is, the lower edges of the two backrest side plates 220, form stop surfaces 222. The backrest portion 200 can pivot relative to the housing 110 until the stop surface 222 abuts against the limiting rib 720 to limit the pivot angle between the backrest portion 200 and the housing 110. In this embodiment, the stop surface 222 abuts against the limiting rib 720 when the backrest portion 200 pivots relative to the housing 110 to a sitting position suitable for infants and young children. This prevents excessive pivoting of the backrest 200 relative to the shell 110 from causing safety hazards or an uncomfortable riding experience for infants and young children.

[0174] Furthermore, such as Figure 32 As shown, the mounting portion 710 protrudes toward the backrest portion 200, and the backrest portion 200 is provided with a relief recess 250 corresponding to the mounting portion 710 to allow the backrest portion 200 to pivot relative to the housing 110.

[0175] Furthermore, such as Figures 26 to 28 As shown, the backrest extension 230 is provided with a sliding hole 231. The portion of the shell body 112 that is relatively away from the leg rest 150, i.e., the portion of the shell body 112 that overlaps with the backrest extension 230, is provided with a connecting hole 111. One of the sliding hole 231 and the connecting hole 111 is a strip-shaped hole, and the sliding hole 231 and the connecting hole 111 at least partially overlap. A sliding pin (not shown in the figure) passes through the sliding hole 231 and the connecting hole 111 to guide the backrest 200 to move relative to the shell 110 in the front-back direction. When the backrest 200 rotates relative to the shell 110, the backrest extension 230 or the backrest 200 is driven to move relative to the shell body 112 in the front-back direction along the infant carrier 1000. The movement of the backrest extension 230 or the backrest 200 can be guided by the cooperation of the sliding pin, the sliding hole 231, and the connecting hole 111.

[0176] The infant carrier 1000 according to the second embodiment of the present invention can be adjusted to suit the infant's sitting posture simply by rotating the backrest 200, without involving the linkage between other parts (such as the backrest and the leg rest), making adjustment convenient and the structure simple.

[0177] Furthermore, it should be understood that the backrest assembly 200 shown in the second embodiment can also be applied to the infant carrier of the first embodiment. Accordingly, the backrest extension 230 is provided with a sliding hole 231, and the portion of the housing 110 corresponding to the backrest extension is also provided with a connecting hole. A sliding pin (not shown in the figures) passes through the sliding hole 231 and the connecting hole to guide the backrest 200 to move relative to the housing 110 in the front-back direction. When the backrest 200 rotates relative to the housing 110, the backrest extension 230 or the backrest 200 is driven to move relative to the housing 110 in the front-back direction of the infant carrier 1000. The movement of the backrest extension 230 or the backrest 200 can be guided by the cooperation of the sliding pin, the sliding hole 231, and the connecting hole.

[0178] like Figure 39 and Figure 40As shown, the structure of the infant carrier 1000 proposed in the third embodiment of this utility model is largely the same as that in the second embodiment, except that the backrest 200 and leg rest 150 of the infant carrier 1000 are connected to the front and rear sides of the housing 110, and the leg rest 150 is fixedly connected to the housing 110. In this embodiment, the leg rest 150 is fixedly connected to the housing 110 by fasteners such as screws. The backrest 200 and the housing 110 are pivotally connected to a fixed first pivot point 101. One of the backrest 200 and the housing 110 may also be provided with a limiting protrusion 260 and the other with a limiting groove 1300. The limiting protrusion 260 is inserted into the limiting groove 1300. When the backrest 200 pivots relative to the housing 110, the limiting protrusion 260 slides in the limiting groove 1300, thereby guiding the rotation stroke of the backrest 200 and making the rotation more stable. Specifically, the limiting groove 1300 is provided in the arc-shaped groove on the rear edge of the shown shell side plate, the arc-shaped groove having a first end 131 and a second end 132. When the pivot angle between the backrest 200 and the shell 110 is at its minimum, that is, when the infant carrier 1000 is suitable for the infant's sitting posture, the limiting protrusion 260 moves to the first end 131 of the limiting groove 1300, as shown. Figure 39 As shown. When the pivot angle between the backrest 200 and the housing 110 is at its maximum, i.e., when the infant carrier 1000 is suitable for the infant's sitting or lying position, the limiting protrusion 260 moves to the second end 132 of the limiting groove 1300, as shown. Figure 40 As shown. In this embodiment, the first end 131 is located in front of and above the second end 132. The two backrest side plates 220 of the backrest portion 200 are provided with limiting protrusions 260, and the two shell side plates 113 of the shell 110 are respectively provided with limiting grooves 1300 that can slide and cooperate with the two limiting protrusions 260.

[0179] In this embodiment, the position of the first pivot point 101 between the backrest portion 200 and the housing 110, as well as the position of the engagement groove 711, are similar to those in the second embodiment. In this embodiment, the first pivot point 101 is located on the lower front side of the handle joint portion 102, and the mounting portion 710 is located behind the handle joint portion 102 and at the upper edge of the side of the housing 110 facing the seating space. Specifically, the first pivot point 101 is located slightly below the middle of the housing side plate 113. The limiting protrusion 260 and the limiting groove 1300 are located at the rear of the housing 110. In this embodiment, both housing side plates 113 are provided with mating holes 1220 located at the first pivot point 101, and both backrest side plates 220 are provided with corresponding pivot pins 223 that can be inserted and mated with the pivot holes 221, thus realizing the pivot connection between the housing side plate 113 (or housing 110) and the backrest side plate 220 (or backrest portion 200). In this embodiment, the position of the pivot point 101 is relatively fixed, that is, the pivot pin 223 can only pivot and cannot move up and down or back and forth.

[0180] like Figure 41 and Figure 42 As shown, the structure of the infant carrier 1000 proposed in the fourth embodiment of this utility model is largely the same as that in the third embodiment, except that the backrest 200 and the leg rest 150 are pivotally connected to the third pivot point 104 by a pin, and the leg rest 150 and the shell 110 are pivotally connected to the second pivot point 103. The leg rest 150 can rotate relative to the shell 110 around the second pivot point 103. Specifically, one of the leg rest 150 and the shell 110 may be provided with a rotating pin (not shown in the figure), and the other may be provided with a rotating hole (not shown in the figure). The leg rest 150 and the shell 110 are pivotally connected to the second pivot point 103 by the insertion and cooperation of the rotating pin and the rotating hole. The pin at the third pivot point 104 can slide along the height direction of the shell 110. Specifically, the front side of each of the two shell side plates 113 is provided with a mating hole 1220, which is arranged along the height direction of the shell 110. The rear sides of the two backrest side panels 220 are respectively pivotally connected to the leg rest 150 via two pivot pins 223. Each pivot pin 223 is inserted into a corresponding mating hole 1220 and can move along the mating hole 1220. Thus, when the leg rest 150 rotates relative to the housing 110, the leg rest 150 will cause the backrest 200 pivotally connected to it to flip backward, and the pivot pin 223 will slide along the height direction of the housing 110 within the mating hole 1220. In this embodiment, the position of the third pivot point 104 between the backrest 200 and the leg rest 150 and the setting position of the mounting part 710 are similar to those in the second embodiment. In this embodiment, the third pivot point 104 is located on the lower front side of the handle joint 102, and the mounting part 710 is located behind the handle joint 102 and at the upper edge of the side of the housing 110 facing the seating space.

[0181] Furthermore, the backrest 200 is movable relative to the housing 110. Specifically, a movable protrusion 270 can be provided on one of the backrest 200 and the housing 110, and a movable elongated groove 140 can be provided on the other. The movable protrusion 270 is inserted into the movable elongated groove 140 and can move along the movable elongated groove 140. When the leg rest 150 rotates relative to the housing 110, and the third pivot point 104 between the leg rest 150 and the backrest 200 moves in the height direction, the backrest 200 will move relative to the housing 110 in the front-back direction. The provision of the movable protrusion 270 and the movable elongated groove 140 can guide this relative movement between the backrest 200 and the housing 110.

[0182] The aforementioned adjustment device and infant carrier have at least the following technical effects:

[0183] The aforementioned infant carrier adjustment device 600 selectively restricts the angular position of the backrest 200 relative to the housing 110 via a locking mechanism 610 disposed between the housing 110 and the backrest 200. Simultaneously, an operating mechanism 620 switches the locking mechanism 610 from a locked state to an unlocked state. This allows the user to adjust the angular position of the backrest 200 simply by operating the operating mechanism 620, without requiring any other operations. It is convenient to use, and adapts to different sitting postures of infants and toddlers by adjusting only the angular position of the backrest 200 relative to the housing 110, without involving the linkage between other components. The structure is simple and easy to implement.

[0184] It is understood that the linkage arrangement of the backing component and the housing in the second to fourth embodiments of this utility model can be applied to the first embodiment, and the pivot structure of the first embodiment of this utility model can also be applied to the second to fourth embodiments. This utility model will not repeat the description in this regard.
