Description

Technical Field

[0001] The present disclosure generally relates to child carriers, and more particularly to an adjustment mechanism for ISOFIX connectors, a safety seat base, and a safety seat.

Background Art

[0002] Some currently commercially available safety seat bases can often engage with both infant safety seats and child safety seats. Child safety seats are generally rotatably engaged with a vehicle seat base so that they can be rotated for forward or rearward use as needed, and infant safety seats can only be rotated for rearward use.

[0003] In addition, the safety seat can be attached to the vehicle through the ISOFIX system. The ISOFIX system generally includes connectors such as ISOFIX connecting rods arranged on the safety seat and anchors such as ISOFIX snap rings arranged on the vehicle. To adapt to different vehicle models and adjust the angle of the safety seat, the safety seat is provided with an adjustment mechanism for controlling the ISOFIX connector to extend from the bottom of the safety seat or retract into the bottom. The adjustment mechanism is generally arranged as a multi-stage adjustment structure to facilitate the user to adjust the distance between the safety seat and the ISOFIX connector during the installation of the safety seat. In known safety seats, operating members for operating the adjustment mechanism, such as operating keys, are arranged on both sides of the bottom of the safety seat, so that the user can unlock the adjustment mechanism by pressing the operating members on both sides of the safety seat, enabling the user to adjust the distance between the safety seat and the ISOFIX connector. When the user releases the operating member and stops operating the operating member, the adjustment mechanism can self-lock and lock the ISOFIX connector in the target position.

DETAILED DESCRIPTION OF THE INVENTION

[0011] To make the objectives, technical solutions, and advantages of the present disclosure more apparent, the present disclosure will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to interpret the present disclosure and are not intended to limit the protection scope of the present disclosure.

[0012] Note that when an element is referred to as being "fixed to" another element, that element may be disposed directly on the other element or there may be intervening elements. When an element is considered to be "connected to" another element, that element may be directly connected to the other element or intervening elements may coexist. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not mean a specific embodiment.

[0013] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which the present disclosure belongs. The terms used in the description of the present disclosure herein are for the purpose of describing specific embodiments only and are not intended to limit the present disclosure. The term "and / or" used herein includes any and all combinations of one or more of the associated listed items.

[0014] As shown in FIG. 1, an embodiment of the present disclosure provides a safety seat. The safety seat includes a safety seat base 1 and a safety seat body 2. The safety seat body 2 is a safety seat body for infants suitable for infants or children under about 4 years old, or a safety seat body for children suitable for children over about 4 years old.

[0015] The safety seat base 1 includes a mounting base 101, a rotating plate 102, an engaging mechanism 100, a connecting mechanism 200, an operating mechanism 300, and an indicating mechanism 400. As shown in FIGS. 2 and 3, the rotating plate 102 is rotatably disposed on the mounting base 101, and the rotating plate 102 has a first rotating position as shown in FIG. 2 and a second rotating position as shown in FIG. 3. Specifically, as shown in FIGS. 2, 5, and 11, the rotating plate 102 includes an upper cover 108 and a lower cover 109 that fit together. Substantially the central portion of the mounting base 101 includes a circular mounting receptacle 106. The mounting base 101 includes an annular mounting rib 107 disposed along the wall of the mounting receptacle 106. The mounting rib 107 is disposed between the upper cover 108 and the lower cover 109 to realize a rotatable connection between the rotating plate 102 and the mounting base 101.

[0016] As shown in FIG. 4, the engaging mechanism 100 is configured to engage the rotating plate 102 with the safety seat body 2. Therefore, when the safety seat body 2 is engaged with the rotating plate 102, the safety seat body 2 can rotate with the rotating plate 102 relative to the mounting base 101. As shown in FIG. 2, when the safety seat body 2 rotates to the first rotating position together with the rotating plate 102, the safety seat body 2 is in a rear-facing state. That is, in this case, the front of the safety seat body 2 of the safety seat installed on the vehicle seat faces the rear of the vehicle. As shown in FIG. 3, when the safety seat body 2 rotates to the second rotating position together with the rotating plate 102, the safety seat body 2 is in a forward-facing state. That is, in this case, the safety seat body 2 of the safety seat installed on the vehicle seat faces the front of the vehicle. It should be understood that the safety seat body for infants can only be used in the rear-facing state to ensure the safety of infants or children under 4 years old. However, the safety seat body for children can be used in both the rear-facing state and the forward-facing state. In the safety seat according to the present disclosure, the safety seat body for children or the safety seat body for infants can only be removed from the safety seat base 1 in the rear-facing state, preventing misuse and potential safety risks.

[0017] Specifically, as shown in FIGS. 3 and 4, an engagement groove 103 is provided in the upper cover 108 of the rotary plate 102. The engagement mechanism 100 is mounted inside the rotary plate 102, that is, positioned within the space defined by the upper cover 108 and the lower cover 109, and a lock hook 110 (to be described in detail later) of the engagement mechanism 100 protrudes into the engagement groove 103. At the bottom of the safety seat body 2, an engagement rod (not shown) for engaging with the lock hook 110 is provided. The engagement rod engages with the engagement groove 103 and is locked by the lock hook 110, realizing the engagement and locking between the rotary plate 102 and the safety seat body 2. When the engagement rod is disengaged from the lock hook 110, the safety seat body 2 can be removed from the rotary plate 102.

[0018] In the present disclosure, as shown in FIGS. 2 and 3, the rotating plate 102 is provided with four engaging grooves 103. Two engaging grooves 103 are respectively provided at the front end portion and the rear end portion of the rotating plate 102. The two engaging grooves 103 at each end portion are spaced apart from each other. It should be noted that the front end portion and the rear end portion in this specification do not refer to the front and rear of the rotating plate 102 with respect to the traveling direction of the vehicle, but refer to the front and rear of the rotating plate 102. Specifically, the front end portion of the rotating plate 102 refers to the end portion that engages with the end portion away from the backrest of the safety seat body 2, and the rear end portion of the rotating plate 102 refers to the end portion that engages with the end portion adjacent to the backrest of the safety seat body 2. For example, as shown in FIG. 2, when the safety seat body 2 rotates to the first rotation position together with the rotating plate 102, the safety seat body 2 is in a rear-facing state. In the rear-facing state, the rear end portion of the rotating plate 102 is adjacent to the display screen 101a such that the higher end portion of the rotating plate 102 shown in FIG. 2 is adjacent to the display screen 101a (to be described in detail later), while the front end portion of the rotating plate 102 is away from the display screen 101a such that the lower end portion of the rotating plate 102 shown in FIG. 2 is away from the display screen 101a. As shown in FIG. 3, when the rotating plate 102 rotates from the first rotation position to the second rotation position, the front end portion of the rotating plate 102 is adjacent to the display screen 101a, while the rear end portion of the rotating plate 102 is away from the display screen 101a. Correspondingly, four engaging mechanisms 100 are provided, and each engaging mechanism 100 is arranged corresponding to one engaging groove 103, and the locking hook 110 of each engaging mechanism 100 protrudes into one engaging groove 103. Four or two engaging rods are provided at the bottom of the safety seat body 2. Correspondingly, four or two engaging rods engage with the four engaging grooves 103. Naturally, the number of the engaging grooves 103 and the engaging rods is not limited to this, and can be flexibly set as required.

[0019] As shown in FIGS. 4 and 5, in the present disclosure, the four engagement mechanisms 100 have the same structure. Also, the two engagement mechanisms 100 arranged at the front end of the rotary plate 102 are symmetrically arranged, and the two engagement mechanisms 100 arranged at the rear end of the rotary plate 102 are symmetrically arranged. More specifically, the safety seat base 1 is provided with a fixed assembly 104 extending vertically. The engagement mechanism 100 is correspondingly arranged on the fixed assembly 104. Specifically, each fixed assembly 104 includes a first fixed plate 104a and a second fixed plate 104b that face each other and are fixed to the safety seat base 1. For example, the fixed assembly 104 is arranged on the rotary plate 102. Hereinafter, in order to describe the specific structure of the engagement mechanism 100 in detail, one of the engagement mechanisms will be taken as an example.

[0020] As shown in FIGS. 5 and 7, the engagement mechanism 100 includes a locking hook 110, a fixing member 120, a third reset member 130, a stopper 140, and a fourth reset member 150.

[0021] Specifically, as shown in FIGS. 6 and 8, the locking hook 110 is pivotally connected between the first fixed plate 104a and the second fixed plate 104b through a first pivot shaft 113 and has a release position and a closed position. The locking hook 110 has a generally E-shaped structure including a second connection portion 114, a hook portion 111 continuously connected to one side of the second connection portion 114, a first pressing portion 115, and a second pressing portion 116. A locking groove 112 is formed between the hook portion 111 and the first pressing portion 115. The hook portion 111 protrudes into the engagement groove 103. When the locking hook 110 is in the closed position, the engagement rod can be restricted within the locking groove 112. When the locking hook 110 is in the release position, the engagement rod can be disengaged from the locking groove 112.

[0022] Specifically, as shown in FIGS. 6 and 8, the fixing member 120 and the locking hook 110 are fixedly connected and are both pivotally connected between the first fixing plate 104a and the second fixing plate 104b through the first pivot shaft 113. As shown in FIGS. 13 and 14, the third reset member 130 abuts against the fixing assembly 104 and the locking hook 110, and the third reset member 130 biases the locking hook 110 to rotate toward the release position. Specifically, the third reset member 130 has two end portions on one side. The two end portions are fixed to a rivet 104c passing through the first fixing plate 104a and the second fixing plate 104b. The end portion on the other side of the third reset member 130 is fixed to the joint portion between the second connecting portion 114 and the second pressing portion 116. In this embodiment, the third reset member 130 is a torsion spring.

[0023] Specifically, as shown in FIG. 14, one end portion of the stopper 140 is pivotally connected between the first fixing plate 104a and the second fixing plate 104b. The second pivot shaft 142 of the stopper 140 is parallel to the first pivot shaft 113 of the locking hook 110. The other end portion of the stopper 140 protrudes toward the fixing member 120 and is configured to abut against the fixing member 120 so that the locking hook 110 is held in the release position to prevent the rotation of the locking hook 110 toward the closed position during manual pressing. The fourth reset member 150 is mounted on the second pivot shaft 142 of the stopper 140, and the two end portions thereof abut against the first fixing plate 104a and the stopper 140 respectively. The fourth reset member 150 biases the stopper 140 in the direction of abutting against the fixing member 120. More specifically, the stopper 140 includes a protruding portion 141 protruding toward the locking hook 110. The protruding portion 141 protrudes into the engaging groove 103. In this embodiment, the fourth reset member 150 is a torsion spring.

[0024] As shown in FIG. 14, when the engagement rod moves into the engagement groove 103, the engagement rod first presses the stopper 140. Therefore, the stopper 140 rotates against the elastic force of the fourth reset member 150, and the stopper 140 no longer abuts against the fixed member 120. Next, when the engagement rod presses the first pressing portion 115, the lock hook 110 rotates against the elastic force of the third reset member 130, and the hook portion 111 rotates upward relative to the engagement rod, and the lock hook 110 reaches the closed position. In this case, as shown in FIG. 8, the slide member 210 (to be described in detail later) in the connection mechanism 200 engages with the second pressing portion 116 of the lock hook 110, and the lock of the lock hook 110 is maintained in a stable state.

[0025] Correspondingly, as shown in FIG. 14, after the slide member 210 moves and is disengaged from the second pressing portion 116 of the lock hook 110, the stopper 140 rotates under the elastic force of the fourth reset member 150. At the same time, the lock hook 110 rotates to the release position under the elastic force of the third reset member 130, so that the stopper 140 abuts against the fixed member 120 fixed to the lock hook 110 again. The lock hook 110 is held in the release position due to the stopper 140 abutting against the fixed member 120. Due to the combined effect of the third reset member 130 and the fourth reset member 150, the lock hook 110 can rotate quickly to the release position, so that it is more labor-saving and rapid to remove the engagement rod, and the rapid removal of the safety seat body 2 is realized.

[0026] As shown in FIGS. 18 to 20, the connection mechanism 200 is disposed between the rotating plate 102 and the mounting base 101. The connection mechanism 200 includes a slide member 210, a second reset member 220, a drive member 230, a reinforcing pin 240, and a fifth reset member 250.

[0027] Specifically, as shown in FIGS. 9 to 12, the slide member 210 is movably disposed within the rotary plate 102. For example, the slide member 210 is movable along the front-rear direction of the rotary plate 102, and the slide member 210 is configured to rotate together with the rotary plate 102. As shown in FIG. 7, the slide member 210 is configured to abut against the four lock hooks 110 and simultaneously hold the four lock hooks 110 in the closed position.

[0028] As shown in FIGS. 5 to 7, the slide member 210 is generally rectangular in shape. Block portions 211 are provided at the four corners of the slide member 210, respectively. Correspondingly, the four block portions 211 abut against the four locking hooks 110, respectively. As shown in FIGS. 8 and 12, the block portion 211 is provided with a pressing slope 211a and an engaging rib 211b, respectively. The slide member 210 has a locked position and an unlocked position. As shown in FIGS. 5 and 8, when the slide member 210 is in the locked position, its four block portions 211 simultaneously hold the four locking hooks 110 in the closed position, and the engaging ribs 211b on the four block portions 211 engage with the second pressing portions 116 of the four locking hooks 110, respectively. As shown in FIGS. 9 and 12, when the rotary plate 102 is in the first rotational position (the state where the safety seat body 2 faces backward) and the slide member 210 slides to the unlocked position in the direction indicated by F1 in FIG. 9, the engaging ribs 211b on the four block portions 211 are disengaged from the second pressing portions 116 of the four locking hooks 110, respectively, and the four locking hooks 110 pivot to their released positions. In this embodiment, while the slide member 210 slides to the unlocked position, the pressing slopes 211a on the four block portions 211 press the second connecting portions 114 of the fourth locking hooks 110, respectively, to prevent the third reset member 130 from being unable to drive the locking hooks 110 to the released position due to the locking hooks 110 being accidentally caught. In some embodiments, the pressing slope 211a is alternatively omitted. As shown in FIGS. 9 and 12, the four locking hooks 110 then abut against the four block portions 211 again, respectively, to hold the slide member 210 in the unlocked position. In this way, one slide member 210 drives the four locking hooks 110 simultaneously, realizing synchronized locking and unlocking, and simplifying the structure.

[0029] Furthermore, one end of the second reset member 220 is fixed to the slide member 210, and the other end is fixed to the upper cover 108. Specifically, as shown in FIGS. 17 and 18, a fixing hook 214 is provided at the bottom of the slide member 210, and a fixing post 108a is provided at the bottom of the upper cover 108. One end of the second reset member 220 is disposed on the fixing hook 214, and the other end of the second reset member 220 is sleeve-connected to the fixing post 108a. The second reset member 220 biases the slide member 210 and slides it toward its locked position. Due to the elastic force of the second reset member 220, the slide member 210 always receives a biasing force to abut against the locking hook 110, so that the slide member 210 can hold the locking hook 110 in the closed position.

[0030] As shown in FIG. 5, the second reset member 220 is a tension spring, but the present disclosure is not limited thereto. In the present disclosure, two second reset members 220 are provided and are spaced apart. One end of each second reset member 220 is connected to the slide member 210, and the other end is connected to the upper cover 108. The second reset member 220 always applies a force to pull the slide member 210 to the rear end of the upper cover 108 of the rotary plate 102, that is, always biases the slide member 210 to move to the rear end of the upper cover 108 of the rotary plate 102.

[0031] Referring to FIGS. 5 to 8, when the engagement rod presses the stopper 140, the stopper 140 rotates and no longer contacts the fixing member 120. Then, when the engagement rod presses the first pressing portion 115, the lock hook 110 rotates upward relative to the engagement rod, and the lock hook 110 reaches the closed position. In this process, both the third reset member 130 and the fourth reset member 150 are deformed. When the lock hook 110 is in the closed position, it is held in the closed position due to the engagement of the slide member 210 with the second pressing portion 116 of the lock hook 110. As shown in FIGS. 9 to 12, when the slide member 210 slides to the unlocking position in the direction indicated by F1, the slide member 210 does not apply a force to the lock hook 110, the fourth reset member 150 returns to its original form, drives the stopper 140 to rotate, the third reset member 130 returns to its original form, and drives the lock hook 110 to automatically pivot to the release position in the direction indicated by F3 in FIG. 8, thereby releasing the lock of the lock hook 110 with respect to the engagement rod and enabling the engagement rod to move out of the engagement groove 103, thereby enabling the safety seat body 2 to be removed from the rotating plate 102. As shown in FIGS. 13 and 14, when the lock hook 110 is in the release position, the stopper 140 contacts the fixing member 120 fixed to the lock hook 110, holds the lock hook 110 in the release position, and the slide member 210 moves in the direction opposite to the direction indicated by F1 under the force of the second reset member 220 until the four block portions 211 respectively contact the second pressing portions 116 of the four lock hooks 110 and are held in the unlocking position.

[0032] Further, as shown in FIGS. 19 and 20, the slide member 210 includes a transmission rib 212 on the side facing the mounting base 101. The transmission rib 212 penetrates the lower cover 109 and protrudes into the mounting base 101. In this embodiment, the transmission rib 212 is positioned at a position near the front end of the lower cover 109 on the rotary plate 102. In this embodiment, the transmission rib 212 is a part of the slide member 210, that is, the slide member 210 including the transmission rib 212 has an integrally formed structure. In this way, on the one hand, the manufacturing and assembly steps can be simplified, and on the other hand, the strength of the transmission rib 212 can also be ensured. In other embodiments, the transmission rib 212 is an element independent of the slide member 210 and is fixed to the slide member 210 by riveting, welding, etc. In order to further improve the strength of the transmission rib 212, a reinforcing pin 240 is further embedded and fixed in the transmission rib 212 so as to extend the life of the transmission rib 212. A pressing convex portion 213 extending toward the mounting base 101 is provided at a substantially central portion of the slide member 210.

[0033] Specifically, as shown in FIGS. 19 and 20, the drive member 230 is movably disposed on the mounting base 101 at a position adjacent to the rear end thereof. For example, the drive member 230 is movable along the front-rear direction of the mounting base 101. The drive member 230 is generally rectangular in shape. The side of the drive member 230 adjacent to the rear end of the mounting base 101 is connected to the operation assembly 300 (see FIG. 32), and a second pressing groove 231 is provided on the other side of the drive member 230. It should be noted that in this specification, since the mounting base 101 is fixed to the vehicle, the front end and the rear end of the mounting base 101 coincide with the front and rear in the traveling direction of the vehicle. When the rotary plate 102 rotates to the first rotation position, that is, when the rotary plate 102 is disposed rearward, the transmission rib 212 is positioned in the second pressing groove 231, and the transmission rib 212 is configured to abut against the groove wall of the second pressing groove 231.

[0034] In this way, when the rotating plate 102 rotates to the first rotation position, that is, when the rotating plate 102 is arranged backward as shown in FIGS. 2 and 20, if the driving member 230 is driven by the operation assembly 300 to move in the direction indicated by F2, the groove wall of the second pressing groove 231 presses the transmission rib 212 and moves it in the same direction F2, whereby the slide member 210 also moves in the direction F2. When the slide member 210 slides to the unlocking position in the direction F2, the slide member 210 does not apply force to the locking hook 110, the fourth reset member 150 returns to its original form, drives the stopper 140 to rotate, the third reset member 130 returns to its original form, and drives the locking hook 110 to automatically pivot to the unlocking position in the direction indicated by F3 in FIG. 12, thereby releasing the lock of the locking hook 110 on the engaging rod and enabling the engaging rod to move out of the engaging groove 103, thereby enabling the safety seat body 2 to be removed from the rotating plate 102.

[0035] When the rotating plate 102 rotates to the second rotation position, that is, when the rotating plate 102 is arranged forward as shown in FIG. 3, the slide member 210 and its transmission rib 212 rotate to a position away from the rear end of the mounting base 101 together with the rotating plate 102, that is, to a position away from the driving member 230. Therefore, even if the driving member 230 is driven by the operation assembly 300 to move, the driving member 230 cannot press and move the transmission rib 212, that is, the slide member 210 cannot be driven to move to unlock the engagement mechanism 100. In this way, the safety seat body 2 can only be removed when rotating to the first rotation position (that is, in the backward state), which can prevent the misuse that occurs when the user engages the infant safety seat body with the safety seat base 1 after the child safety seat body in the second rotation position is removed and the infant safety seat body is used with the front facing state, thereby improving the safety rate.

[0036] As shown in FIGS. 19 and 20, one end of the fifth reset member 250 abuts against the side of the drive member 230 adjacent to the rear end of the mounting base 101, and the other end abuts against the mounting base 101. The fifth reset member 250 biases the drive member 230 to move in a direction opposite to the direction in which the drive member 230 is pulled by the operation assembly 300, that is, in a direction opposite to the direction F2 in the figure. In this embodiment, the fifth reset member 250 is a spring. In this way, when the safety seat body 2 is removed from the safety seat base 1, the operation member 310 described later is released, and the drive member 230 is driven and reset by the fifth reset member 250, the groove wall of the second pressing groove 231 of the drive member 230 no longer presses the transmission rib 212 of the slide member 210. Thereby, the drive member 230 does not apply a force to the slide member 210, and the slide member 210 moves in a direction opposite to the direction indicated by F1 under the force of the second reset member 220 until the four block portions 211 respectively abut against the second pressing portions 116 of the four locking hooks 110 and are held in the unlocking position. In this embodiment, the direction F1 is substantially the same as the direction F2.

[0037] In another embodiment of the present disclosure, a connection mechanism 200' is provided. The connection mechanism 200' is disposed between the rotating plate 102 and the mounting base 101. The connection mechanism 200' includes a slide member 210', a second reset member 220', a drive member 230', a connection member 240', and a fifth reset member 250'.

[0038] Specifically, as shown in FIGS. 27 to 28, the slide member 210' is movably disposed within the rotating plate 102, and the slide member 210' is configured to abut against the four locking hooks 110 and hold the four locking hooks 110 in the closed position simultaneously.

[0039] The slide member 210' is generally rectangular in shape, and block portions 211 are respectively provided at the four corners of the slide member 210'. Correspondingly, the four block portions 211 respectively abut against the four locking hooks 110. The block portions 211 are respectively provided with a pressing slope 211a and an engaging rib 211b. The slide member 210' has a locked position and an unlocked position. When the slide member 210' is in the locked position, its four block portions 211 simultaneously hold the four locking hooks 110 in the closed position, and the engaging ribs 211b on the four block portions 211 respectively engage with the second pressing portions 116 of the four locking hooks 110. When the slide member 210' slides to the unlocked position in the direction indicated by F1 in the figure, the four locking hooks 110 pivot to their released positions. In this embodiment, while the slide member 210' slides to the unlocked position, the pressing slopes 211a on the four block portions 211 respectively press down the second connecting portions 114 of the four locking hooks 110, preventing the third reset member 130 from being unable to drive the locking hooks 110 to the released position due to the locking hooks 110 being accidentally caught. In some embodiments, the pressing slope 211a is alternatively omitted. Then, the four locking hooks 110 respectively abut against the four block portions 211 again to hold the slide member 210' in the unlocked position, and the four locking hooks 110 are simultaneously driven by the slide member 210' to achieve synchronous locking and unlocking, which simplifies the structure.

[0040] Furthermore, as shown in FIGS. 27 and 28, a first pressing groove 212' is provided on the side of the slide member 210' facing the mounting base 101. In this embodiment, the first pressing groove 212' is arranged at a position corresponding to the position of the lower cover 109 adjacent to the rear end portion of the lower cover 109. A pressing protrusion 213' extending toward the mounting base 101 is provided at approximately the central portion of the slide member 210'.

[0041] The second reset member 220' has one end fixed to the slide member 210' and the other end fixed to the upper cover 108. In addition, the specific structure and function of the second reset member 220' are the same as those of the second reset member 220 in the above embodiment, and the details thereof will not be repeatedly described here.

[0042] As shown in FIGS. 27 to 28, the drive member 230' is movably disposed at a position adjacent to the front end portion of the mounting base 101. The drive member 230' is generally rectangular in shape. The side of the drive member 230' adjacent to the front end portion of the mounting base 101 is connected to the operation assembly 300, and a second pressing groove 231' is provided on the other side of the drive member 230'.

[0043] The connecting member 240' is pivotally connected to the rotating plate 102. The drive member 230' is configured to be operable to drive the connecting member 240' to rotate when the rotating plate 102 rotates to the first rotation position. The rotation of the connecting member 240' drives the slide member 210' to slide, thereby driving the engagement mechanism 100 to release the lock. The connecting member 240' has, as a specific example, a first end portion and a second end portion. When the rotating plate 102 rotates to the first rotation position, the first end portion abuts against the slide member 210', and the second end portion abuts against the drive member 230'.

[0044] Specifically, as shown in FIGS. 27 and 28, the connecting member 240' is pivotally connected to the lower cover 109 and is positioned at a location adjacent to the rear end portion of the lower cover 109. The connecting member 240' is generally in a strip shape. The two end portions of the connecting member 240' are the first end portion 241' and the second end portion 242', respectively. The first end portion 241' is positioned within the first pressing groove 212'. When the rotating plate 102 rotates to the first rotation position, that is, when the rotating plate 102 is arranged rearward, the second end portion 242' is positioned within the second pressing groove 231' of the driving member 230', the first end portion 241' is configured to abut against the groove wall of the first pressing groove 212', and the second end portion 242' is configured to abut against the groove wall of the second pressing groove 231'. Thus, when the rotating plate 102 rotates to the first rotation position, that is, when the rotating plate 102 is arranged rearward, as shown in FIGS. 29 and 30, when the driving member 230' is driven by the operating assembly 300 to move in the direction indicated by F2' (opposite to the direction F2 shown in FIG. 20), the groove wall of the second pressing groove 231' presses down the connecting member 240' to move it in the direction F4 shown in FIG. 28, and the first end portion 241' of the connecting member 240' presses down the sliding member 210' to move it in the direction indicated by F1 toward the unlocking position. Since the sliding member 210' does not apply a force to the locking hook 110, the fourth reset member 150 returns to its original form, drives the stopper 140 to rotate, the third reset member 130 returns to its original form, and drives the locking hook 110 to automatically pivot to the unlocking position in the direction indicated by F3 in FIG. 12, thereby releasing the lock of the locking hook 110 on the engaging rod and enabling the engaging rod to move out of the engaging groove 103, thereby enabling the safety seat body 2 to be removed from the rotating plate 102.When the rotating plate 102 rotates to the second rotation position, that is, when the rotating plate 102 is arranged facing forward as shown in FIG. 31, the connecting member 240' rotates to a position away from the front end of the mounting base 101 together with the rotating plate 102, that is, to a position away from the driving member 230'. Therefore, even if the driving member 230' is driven by the operation assembly 300 and moves in the direction indicated by F2', the driving member 230' cannot push down and move the connecting member 240', that is, it cannot drive the slide member 210' to move and unlock the engagement mechanism 100. In other words, when the rotating plate 102 rotates to the second rotation position, the second end portion 242' and the driving member 230' are separated and cannot contact each other. In this way, the safety seat body 2 can only be removed from the safety seat base 1 when rotating to the first rotation position (that is, in the state facing backward), which can prevent the misuse that the infant safety seat body is used in the state facing forward, which is caused by the user engaging the infant safety seat body with the safety seat base 1 after the child safety seat body in the second rotation position is removed, thereby improving the safety rate.

[0045] As shown in FIGS. 27 and 28, one end of the fifth reset member 250' abuts against the side of the driving member 230' adjacent to the rear end of the mounting base 101, and the other end abuts against the mounting base 101. The fifth reset member 250' biases the driving member 230' to move in a direction opposite to the direction in which the driving member 230' is pulled by the operation assembly 300, that is, in a direction opposite to the direction F2' in FIG. 28.

[0046] As shown in FIGS. 32 to 34, the operation assembly 300 includes an operation member 310, a tension member 320, a pivot shaft, and a sixth reset member 340 (see FIG. 33).

[0047] As shown in FIG. 32, two operating members 310 are provided to facilitate user operation. They are each movably arranged on two sides of the mounting base 101 and are exposed on the side surface of the mounting base 101. Of course, in other embodiments, the operating member 310 may also be arranged at the front end of the mounting base 101. The operating member 310 positioned at the side of the mounting base 101 is easier to operate compared to the operating member 310 positioned at the front end of the mounting base 101. The front end of the mounting base 101 is often difficult to reach due to the obstruction of the safety seat body 2 and the front vehicle seat. On the other hand, since the side of the mounting base 101 faces the operator directly, it is easier to operate. For example, the operating member 310 is a handle.

[0048] As shown in FIGS. 33 and 34, hereinafter, in order to specifically introduce the structure of the operating member 310, one operating member 310 will be taken as an example. The operating member 310 includes an operating portion 311 arranged continuously, a pivoting portion 312, and a first connecting portion 313. Pivoting shafts (not shown) are respectively provided on two sides of the mounting base 101. Each operating member 310 is pivotally connected to one of the pivoting shafts on the side through the pivoting portion 312, and the operating portion 311 and the first connecting portion 313 are respectively positioned on two sides of the pivoting shaft. The operating portion 311 is operable, and the first connecting portion 313 is configured to be connected to the tension member 320. In this way, when the operating portion 311 is operated to rotate around the pivoting shaft, the first connecting portion 313 can be simultaneously driven to rotate, and the tension member 320 can be pulled and moved.

[0049] As shown in FIG. 32, correspondingly, two tension members 320 are provided, and each tension member 320 is connected between the first connection portion 313 of the operating member 310 on one side and the driving member 230. As shown in FIGS. 37 and 38, when the safety seat base 1 includes the coupling mechanism 200', each tension member 320 is connected between the first connection portion 313 and the driving member 230'. When the operating portion 311 is operated, the operating member 310 is rotated around the pivot shaft, thereby driving and moving the tension member 320 through the first connection portion 313. Thereafter, the tension member 320 pulls the driving member 230 and moves it in the direction F2 in FIG. 24. In an alternative example, when the operating portion 311 is operated, the operating member 310 is rotated around the pivot shaft, thereby driving and moving the tension member 320 through the first connection portion 313. Thereafter, the tension member 320 pulls the driving member 230' and moves it in the direction F2' in FIG. 30. In this embodiment, the tension member 320 is configured to pull the driving member 230 by operating and moving the operating portion 311 upward as shown in FIG. 36, or the tension member 320 can pull the driving member 230' by operating and moving the operating portion 311 upward as shown in FIG. 38. Of course, in other embodiments, the operating portion 311 may be operated in other ways. The tension member 320 is a steel wire rope, but is not limited thereto, and may be other similar components having toughness and strength. Specifically, as shown in FIG. 36, a guide member 105 is provided on the mounting base 101. The guide member 105 is provided with an arc-shaped guide portion. One end of the tension member 320 is connected to both sides of the operating portion 311 of the operating member 310, and the other end of the tension member 320 enters the mounting base 101 along the direction indicated by F6 (that is, the lateral direction of the mounting base 101), bypasses the guide portion under the guidance of the guide member 105, and is connected to the driving member 230 along the direction indicated by F7 (that is, the longitudinal direction of the mounting base 101).

[0050] Furthermore, two sixth reset members 340 are also provided. Each sixth reset member 340 is disposed between one of the operating members 310 and the mounting base 101. The sixth reset member 340 constantly rotates the operating member 310 until the operating member 310 reaches a position where it is not operated. Specifically, the sixth reset member 340 is a torsion spring. A spring coil of the torsion spring is connected to the pivot shaft in a sleeve manner, and two ends of the torsion spring are respectively in contact with the operating portion 311 and the mounting base 101. Thus, when the operating portion 311 is moved upward (or downward), the torsion spring is deformed. When the external force applied to the operating portion 311 is removed, the operating portion 310 can be reset by receiving the elastic force of the sixth reset member 340.

[0051] Specifically, as shown in FIGS. 20, 22, and 40, the indicating mechanism 400 includes a detection unit 410, a first reset member 420, a sensor 430, and a controller (not shown). It should be understood that regardless of whether the safety seat base 1 includes the connecting mechanism 200 or the connecting mechanism 200', the indicating mechanism 400 has the same structure and can achieve the same function. That is, when comparing the embodiment in which the safety seat base 1 includes the connecting mechanism 200 with the embodiment in which the safety seat base 1 includes the connecting mechanism 200', the only difference lies in the different positions of the indicating mechanism 400 with respect to the connecting mechanism 200 and the connecting mechanism 200'. Therefore, hereinafter, the indicating mechanism 400 will be described by taking the example in which the safety seat base 1 includes the connecting mechanism 200.

[0052] As shown in FIG. 20, the detection unit 410 is specifically a push button movably disposed between the rotary plate 102 and the mounting base 101. For example, the detection unit 410 is specifically disposed to move vertically between the rotary plate 102 and the mounting base 101. A detection rib 411 is provided at one end of the detection unit 410 (i.e., the bottom end of the detection unit 410) positioned within the mounting base 101. In this embodiment, the sensor 430 is a photoelectric sensor 430. The photoelectric sensor 430 is disposed on the mounting base 101 and positioned below the detection unit 410. The photoelectric sensor 430 includes a transmitting end 431 and a receiving end 432 disposed opposite to each other. The transmitting end 431 is configured to send an optical signal to the receiving end 432. As shown in FIGS. 22, 26, and 40, a pressing block 414 is provided at substantially the central portion of the detection unit 410. The pressing block 414 can at least partially extend into the rotary plate 102 so as to abut against the pressing protrusion 213. The pressing block 414 includes a pressing slope 412. When the slide member 210 slides, it presses the pressing slope 412 of the pressing block 414 through the pressing protrusion 213, drives the detection unit 410, and moves it along a direction intersecting the sliding direction of the slide member 210. In this case, the detection rib 411 protrudes into the mounting base 101 and can be detected by the sensor 430. In this embodiment, the inclination direction of the pressing slope 412 is from the rear end portion to the front end portion of the mounting base 101.

[0053] As shown in FIGS. 39 and 40, a protrusion 413 protruding along the radial direction is provided at the end of the detection unit 410 positioned within the rotary plate 102 (i.e., the upper end of the detection unit 410). Two ends of the first reset member 420 are respectively in contact with the lower cover 109 and the protrusion 413. The first reset member 420 constantly moves the detection unit 410 in a direction opposite to the direction in which the detection unit 410 is pressed by the slide member 210. In other words, the first reset member 420 is disposed between the detection unit 410 and the rotary plate 102, and the first reset member 420 constantly rotates the detection unit 410 in a direction away from the mounting base 101. In this embodiment, the first reset member 420 is a spring. Optionally, a plurality of first reset members 420 are provided. For example, in this embodiment, four protrusions 413 are provided, spaced equidistantly in the circumferential direction, and correspondingly, four first reset members 420 are also provided. In other embodiments, more than four or less than four first reset members 420 may be provided.

[0054] When the safety seat body 2 is mounted on the safety seat base 1, that is, when the engagement rod engages with the lock hook 110, the slide member 210 moves to the lock position in a direction opposite to the direction indicated by F1 under the elastic force of the second reset member 220, thereby holding the lock hook 110 in the closed position. At the same time, as shown in FIGS. 20 and 22, the slide member 210 presses the detection unit 410 through the pressing convex portion 213 and moves it in the direction F5. That is, the detection rib 411 moves in the direction F5 and is interposed between the transmission end portion 431 and the reception end portion 432. The reception end portion 432 cannot receive the optical signal from the transmission end portion 431 due to the blocking by the detection rib 411, and sends information indicating that the rotary plate 102 and the safety seat body 2 are engaged at a fixed position to the controller.

[0055] When the operation assembly 300 is operated to drive the slide member 210 through the drive member 230 and slide it to the unlocking position along the direction indicated by F1, the lock hook 110 rotates to the release position, releasing the lock of the lock hook 110 on the engagement rod and enabling the safety seat body 2 to separate from the rotary plate 102. As shown in FIGS. 24 and 26, in this case, the pressing convex portion 213 no longer presses the detection portion 410, and the detection portion 410 is driven by the first reset member 420 and moves away from the sensor 430. Therefore, the detection rib 411 retreats from between the transmission end portion 431 and the reception end portion 432, and the reception end portion 432 stops sending information indicating that the rotary plate 102 and the safety seat body 2 are not engaged or sending information indicating that the rotary plate 102 and the safety seat body 2 are engaged at a fixed position to the controller. The stopper 140 abuts against the fixing member 120 fixed to the lock hook 110 to hold the lock hook 110 at the release position, so that the lock hook 110 cannot be closed. The slide member 210 can move in a direction opposite to the direction indicated by F1 under the elastic force of the second reset member 220 until the four block portions 211 respectively abut against the second pressing portions 116 of the four lock hooks 110 and are held at the unlocking position. In this case, the slide member 210 at the unlocking position is closer to the rear end portion of the mounting base 101 (i.e., the right side in FIG. 26) than the slide member 210 at the locking position, and since the pressing convex portion 213 still does not abut against the protrusion 413 of the detection portion 410, the detection rib 411 still does not intervene between the transmission end portion 431 and the reception end portion 432.

[0056] In this embodiment, the controller sends information indicating that the rotating plate 102 and the safety seat body 2 are engaged in a fixed position, or information indicating that the rotating plate 102 and the safety seat body 2 are not engaged, which is sent by the sensor 430, to a mobile terminal such as a mobile phone to alert the user about the engagement state of the safety seat body 2. Alternatively, in other embodiments, as shown in FIGS. 2 and 3, the display screen 101a is disposed on the mounting base 101. The controller displays on the display screen 101a information indicating that the rotating plate 102 and the safety seat body 2 are engaged in a fixed position, or information indicating that the rotating plate 102 and the safety seat body 2 are not engaged, which is sent by the sensor 430, to alert the user about the engagement state of the safety seat body 2.

[0057] Although the connection mechanisms 200 and 200' have different structures, the connection mechanisms 200 and 200' can achieve the same function. Therefore, in this specification, only the example in which the connection mechanism 200 is applied to the safety seat is used to explain the use process of the safety seat, and the use process is used as a reference for understanding the use process of the safety seat to which the connection mechanism 200' is applied.

[0058] In the using process, when the rotating plate 102 rotates to the first rotation position (i.e., arranged facing backward), as shown in FIG. 2, when attempting to disassemble the safety seat body 2 from the safety seat base 1, the operating member 310 is operated so as to pull the driving member 230 and move in the direction F2 through the tension member 320. Next, the driving member 230 presses the slide member 210 and similarly moves it to the unlocking position in the direction F1, so that the slide member 210 does not apply force to the locking hook 110, the fourth reset member 150 returns to its original form, drives and rotates the stopper 140, the third reset member 130 returns to its original form, and drives the locking hook 110 to automatically pivot to the release position along the direction indicated by F3 in FIG. 8, so that the locking hook 110 releases the lock on the engaging rod, enables the engaging rod to move out of the engaging groove 103 of the locking hook 110, and enables the safety seat body 2 to move away from the rotating plate 102. In this case, the locking hook 110 is driven by the third reset member 130 and is held in the release position due to the stopper 140 abutting against the fixing member 120. By the user releasing the operating member 310, the slide member 210 can move in the direction opposite to the direction indicated by F1 under the elastic force of the second reset member 220 until the four block portions 211 respectively abut against the second pressing portions 116 of the four locking hooks 110 and are held in the unlocking position.

[0059] When it is necessary to reinstall the safety seat body 2 on the safety seat base 1, as shown in FIGS. 9 to 12, the stopper 140 is pressed on the engagement rod to rotate the stopper 140. After the pressing of the fixing member 120 stops, then the engagement rod presses the first pressing portion 115, so that the lock hook 110 rotates upward relative to the engagement rod, and the lock hook 110 reaches the closed position. In this process, both the third reset member 130 and the fourth reset member 150 are deformed. When the lock hook 110 is in the closed position, as shown in FIG. 8, due to the engagement between the slide member 210 and the second pressing portion 116 of the lock hook 110 driven by the second reset member 220, the lock hook 110 is held in the closed position. At the same time, the slide member 210 presses the detection portion 410 through the pressing convex portion 213, so that, as shown in FIG. 20, the detection portion 410 moves in the direction F5 until the detection rib 411 is sensed by the sensor 430. Then, the sensor 430 sends information indicating that the rotary plate 102 and the safety seat body 2 are engaged in a fixed position to the controller. The controller transmits the information indicating that the rotary plate 102 and the safety seat body 2 are engaged in a fixed position to a portable terminal such as the user's mobile phone, or displays the information indicating that the rotary plate 102 and the safety seat body 2 are engaged in a fixed position on the display screen 101a of the mounting base 101 to alert the user.

[0060] When the rotating plate 102 rotates to the second rotation position (i.e., is arranged facing forward), as shown in FIG. 3, the transmission rib 212 of the slide member 210 rotates together with the rotating plate 102 to a position away from the front end of the mounting base 101, that is, a position away from the drive member 230. Therefore, in this case, even if the drive member 230 is driven by the operation assembly 300 and moves along the direction indicated by F2, the drive member 230 and the transmission rib 212 are separated and cannot contact each other. Thus, the drive member 230 cannot press and move the transmission rib 212 to unlock the engagement mechanism 100. In this way, the safety seat body 2 can only be removed when rotating to the first rotation position (i.e., in the rearward state), which can prevent misuse caused by the fact that the safety seat body for children in the second rotation position (e.g., in the forward state) is removed and then the user engages the safety seat body for infants with the safety seat base 1 when the safety seat body for infants is in the forward state, thereby improving the safety rate.

[0061] Of course, the specific arrangement positions and orientations of the relevant parts of the above engagement mechanism 100 and connection mechanism 200 (or connection mechanism 200') are merely examples, and the adaptive modifications made by those skilled in the art to the above embodiments according to the general knowledge in the technical field based on the above are still included within the protection scope of the present disclosure. For example, the transmission rib 212 may also be positioned at a position adjacent to the rear end thereof within the lower cover 109, the drive member 230 is movably arranged corresponding to a position adjacent to the front end thereof within the mounting base 101, and the slide member 210 and the engagement mechanism 100 are correspondingly adjusted such that the movement of the slide member 210 along the opposite direction of F1 can unlock the engagement mechanism 100. In short, as long as the engagement mechanism 100 can be unlocked when the rotating plate 102 is in the first rotation position and the engagement mechanism 100 cannot be unlocked when the rotating plate 102 is in the second rotation position, any variant of the above embodiment can be realized.

[0062] In this specification, the technical effects of the above-mentioned safety seat are described only by way of an example in which the coupling mechanism 200 is applied to the safety seat, and the technical effects are used as a reference for understanding the technical effects of the safety seat to which the coupling mechanism 200' is applied.

[0063] Specifically, in the above-mentioned safety seat base 1, when the rotating plate 102 rotates to the first rotation position with respect to the mounting base 101 (for example, when it is in the rear-facing state), the driving member 230 in the coupling mechanism 200 becomes operable. Since the slide member 210 protrudes at least partially from the mounting base 101 and is drivingly connected to the driving member 230, or the driving member 230 protrudes at least partially from the rotating plate 102 and is drivingly connected to the slide member 210, the driving member 230 can directly drive and move the slide member 210 while moving it so as to drive the engaging mechanism 100 to unlock. In this case, the safety seat base 1 is disengaged from the safety seat body 2, and the safety seat body 2 can be removed from the safety seat base 1. However, when the rotating plate 102 rotates to the second rotation position with respect to the mounting base 101 (for example, until it faces forward), even if the driving member 230 is operated and moved, since the driving member 230 does not contact the slide member 210, the engaging mechanism 100 remains locked, the safety seat base 1 and the safety seat body 2 remain engaged, and the safety seat body 2 cannot be disassembled from the safety seat base 1. With this configuration, after the child safety seat in the second rotation position (for example, the forward-facing state) is removed, when the user engages the infant safety seat with the safety seat base 1, misuse caused by the infant safety seat being in the forward-facing state can be prevented, thereby improving the safety rate.

[0064] In addition, the safety seat base 1 according to the present application may be connected with an adjustment mechanism for the ISOFIX connector. Generally, the ISOFIX connector is adapted to be attached to a connection component adapted to the ISOFIX connector in a vehicle. The adjustment mechanism will be described in detail later with reference to FIGS. 41 to 49.

[0065] Figures 41 and 42 schematically illustrate a partial structure of a safety seat according to an embodiment of the present application. As shown in FIG. 41, the safety seat according to the present application includes an adjustment mechanism S10 and a safety seat base 1. The safety seat base 1 includes a base lower cover S201. The base lower cover S201 defines a mounting cavity S2011.

[0066] The adjustment mechanism S10 is positioned within the mounting cavity S2011 and includes a support portion S100. The support portion S100 is connected to the base lower cover S201. In addition, the adjustment mechanism S10 further includes a slide rod assembly S200. The slide rod assembly S200 includes two slide rods S210. The two slide rods S210 both extend along the length direction L of the safety seat (or the safety seat base 1) and may be spaced apart along the width direction (direction W shown in FIG. 41) of the safety seat. One end of each slide rod S210 is slidably connected to the support portion S100 and releasably locked to the support portion S100, and the other end of each slide rod S210 is connected to an ISOFIX connector S2 such as an ISOFIX connection rod. The ISOFIX connector S2 is adapted to be attached to a connection component compatible with the ISOFIX connector in the vehicle.

[0067] Since the ISOFIX connector S2 is slidably connected to the support portion S100 of the safety seat through the slide rod S210, by locking the slide rod S210 to the support portion S100, the distance between the tip of the ISOFIX connector S2 and the support portion S100 (i.e., the length of the ISOFIX connector S2 extending from the support portion S100) can be defined, and by releasing the slide rod S210 from the support portion S100, the distance between the tip of the ISOFIX connector S2 and the support portion S100 can be adjusted. In some embodiments, a connection component adapted to the ISOFIX connector S2 in the vehicle, such as an ISOFIX snap ring, may be disposed within the vehicle seat. In this way, by being able to attach the ISOFIX connector S2 to the vehicle seat, the safety seat can be attached to the vehicle seat.

[0068] In some embodiments, referring to FIG. 43, the slide rod assembly S200 further includes a connector S220. The two slide rods S210 are both connected to the connector S220. In this embodiment, the connector S220 is disposed between the two slide rods S210, and the connector S220 is formed by extending one of the slide rods S210 to the other of the slide rods S210. The synchronized sliding of the two slide rods S210 can be realized by connecting the two slide rods S210 together through the connector S220. The connector S220 is a connection sheet or a connection rod such as a connection iron sheet or a connection iron rod.

[0069] In some embodiments, referring to FIGS. 41 and 42, the support part S100 further includes two slide sleeves S120 corresponding to two slide rods S110. The two slide sleeves S120 are positioned on two opposite sides of the support part S100. Each of the two slide sleeves S120 is provided with a through hole (not shown), and one end of the corresponding slide rod S210 passes through the through hole and is slidably connected to the support part S100. In this way, the slide connection of the slide rod S210 to the support part S100 can be realized. Specifically, the slide sleeve S120 may be connected to the support part S100 by means such as welding, bolting, or engagement.

[0070] Referring to FIGS. 41 and 42, the adjustment mechanism S10 further includes an adjustment assembly S300 and an operation part S400. The adjustment assembly S300 and the operation part S400 are configured to control the locking or unlocking between the slide rod assembly S200 and the support part S100. In this embodiment, the adjustment assembly S300 includes a connecting part S320 and two engaging members S310. The two engaging members S310 may be spaced apart along the width direction of the safety seat. The two engaging members S310 are configured to releasably lock the slide rod assembly S200 to the support part S100, and the two engaging members S310 are movably connected to the connecting part S320. The connecting part S320 is adapted to drive one of the two engaging members S31 driven by the other of the two engaging members S310, so that the two engaging members S310 move synchronously to lock the slide rod assembly S200 to the support part S100 or release the slide rod assembly S200 from the support part S100.

[0071] Specifically, the connecting effect of the connecting part S320 can lock the slide rod assembly S200 to the support part S100 by synchronously moving the two engaging members S310, or release the slide rod assembly S200 from the support part S100, which can be achieved in various ways. In some embodiments, referring to FIG. 41, when each of the two engaging members S310 is driven by the connecting part S320 to move in a direction to lock the slide rod assembly S200 to the support part S100, the other of the two engaging members S310 is driven to move in a direction to lock the slide rod assembly S200 to the support part S100, thereby locking the slide rod assembly S200 to the support part S100. When each of the two engaging members S310 is driven by the connecting part S320 to move in a direction to release the slide rod assembly S200 from the support part S100, the other of the two engaging members S310 is driven to move in a direction to release the slide rod assembly S200 from the support part S100, thereby releasing the slide rod assembly S200 from the support part S100.

[0072] Referring to FIGS. 41 and 42, the operating part S400 includes two operating members S410 respectively connected to the two engaging members S310. Referring to FIG. 44, for simplicity of description, the two operating members S410 can be the first operating member S410a and the second operating member S410b, and the two engaging members S310 can be the first engaging member S310a and the second engaging member S310b. The first operating member S410a and the second operating member S410b may be spaced apart on two sides of the safety seat in the width direction of the safety seat. In addition, the first operating member S410a and the second operating member S410b are configured on opposite sides of the connecting part S320. The first engaging member S310a and the second operating member S410b are both configured on the same side of the connecting part S320, and the second engaging member S310b and the first operating member S410a are configured on the same side of the connecting part S320.

[0073] The operation part S400 is configured to operate either the first operation member S410a or the second operation member S410b. Thereby, the two engaging members S310 (that is, the first engaging member S310a and the second engaging member S310b) can synchronously release the slide rod assembly S200 from the support part S100. In this way, in the method of operating either the first operation member S410a or the second operation member S410b, by the transmission of the connecting part S320, the two engaging members S310 (that is, the first engaging member S310a and the second engaging member S310b) are driven to move synchronously, release the slide rod assembly S200 from the support part S100, and thereby realize the unlocking between the safety seat and the ISOFIX connector S2. The unlocking operation is simple and user-friendly, and has a simple structure and low manufacturing cost.

[0074] However, the present application is not limited to the above embodiments. In another embodiment, the operation part S400 may include only one operation member S410. Since the two engaging members S310 can be connected to each other, even if there is only one operation member S410, the two engaging members S310 can be driven synchronously to move synchronously, lock the slide rod assembly S200 to the support part S100, or release the slide rod assembly S200 from the support part S100. The operation member S410 may be positioned on both sides of the safety seat in the width direction of the safety seat, or may be configured at another position according to actual requirements, which is not limited in the present application.

[0075] In some embodiments, referring to FIG. 44, the adjustment assembly S300 further includes two elastic members S500 respectively corresponding to the two engaging members S310. Each of the two elastic members S500 is adapted to bias the respective engaging member S310 so that the engaging member S310 always has a tendency to move in a direction to lock the slide rod assembly S200 to the support part S100.

[0076] Thus, when the user does not operate the first operating member S410a and the second operating member S410b, the engaging member S310 is driven by the elastic action of the elastic member S500, and the engaging member S310 always tends to move in a direction to lock the slide rod assembly S200 to the support portion S100. This can ensure that the slide rod assembly S200 is always locked to the support portion S100 when no external force acts on the first operating member S410a and the second operating member S410b, thereby maintaining the length of the ISOFIX connector S2 protruding from the outer surface of the lower base cover S201.

[0077] When either the first operating member S410a or the second operating member S410b is operated, it can be easily understood that it is necessary to overcome the elastic force of the elastic member S500 so that the two engaging members S310 release the slide rod assembly S200 from the support portion S100. When the external force acting on the first operating member S410a and the second operating member S410b is removed, the engaging member S310 is driven by the elastic restoring force of the elastic member S500, and the slide rod assembly S200 is locked to the support portion S100. In an optional embodiment, the elastic member S500 is a spring. Preferably, the elastic member S500 is a coil spring.

[0078] In some embodiments, the safety seat base 1, particularly the base lower cover S201, is provided with at least one mounting port communicating with the mounting cavity. The at least one mounting port is positioned on at least one side of the safety seat and corresponds to the operation part S400. The operation part S400 extends from the at least one mounting port for the user to operate. Referring to FIGS. 41 and 44, when the operation part S400 includes the first operation member S410a and the second operation member S410b, the base lower cover S201 is provided with two mounting ports S2012 communicating with the mounting cavity S2011. The two mounting ports S2012 are positioned on two opposite sides of the safety seat and correspond to the first operation member S410a and the second operation member S410b respectively. Specifically, the first operation member S410a and the second operation member S410b extend from the two mounting ports S2012 respectively for the user to operate. In this way, when the user operates either the first operation member S410a or the second operation member S410b outside the safety seat, unlocking of the ISOFIX connector S2 and the safety seat can be realized, which is simple to operate and easy to use.

[0079] Specifically, referring to FIGS. 44 and 45, each of the first operating member S410a and the second operating member S410b is pivotally arranged. Further, each of the first operating member S410a and the second operating member S410b is pivotable between a reset position and a pressing position, and when pivoting from the reset position to the pressing position, each corresponding engaging member S310 is moved in a direction to release the slide rod assembly S200 from the support portion S100, and when pivoting from the pressing position to the reset position, each corresponding engaging member S310 is moved in a direction to lock the slide rod assembly S200 to the support portion S100. Thus, when the user presses one of the first operating member S410a and the second operating member S410b to pivot it from the reset position to the pressing position, the corresponding engaging member S310 can be driven to move in a direction to release the slide rod assembly S200 from the support portion S100, and the other engaging member S310 is driven by the connecting portion S320 to move synchronously in a direction to release the slide rod assembly S200 from the support portion S100, thereby enabling the length of the ISOFIX connector S2 protruding from the safety seat base 1 to be adjustable. When the user removes the pressing force and enables one of the first operating member S410a and the second operating member S410b to pivot from the pressing position to the reset position as described above, the corresponding engaging member S310 moves in a direction to lock the slide rod assembly S200 to the support portion S100, and the other engaging member S310 is driven by the connecting portion S320 to move synchronously in a direction to lock the slide rod assembly S200 to the support portion S100, thereby locking the slide rod assembly S200 to the support portion S100 so as to fix the length of the ISOFIX connector S2 protruding from the safety seat base 1.

[0080] In some embodiments, referring to FIG. 42, the adjustment assembly S300 further includes two elastic reset members S600 respectively corresponding to the two operating members S410. Each of the two elastic reset members S600 is adapted to bias the corresponding operating member S410 so that the operating member S410 always has a tendency to pivot from the pressing position to the reset position. In this way, when the user does not apply force to either of the two operating members S410, the elastic action of the elastic reset member S600 drives the operating member S410, so that the operating member S410 always has a tendency to pivot from the pressing position to the reset position. This ensures that when no external force acts on the operating member S410, the slide rod assembly S200 is always locked to the support portion S100, and the length of the ISOFIX connector S2 protruding from the safety seat base 1 is constant.

[0081] In addition, it can be easily understood that when the user presses either of the two operating members S410 to pivot from the reset position to the pressing position, it is necessary to overcome the elastic force of the elastic reset member S600. The elastic restoring force of the elastic reset member S600 drives one of the two operating members S410 to pivot from the pressing position to the reset position when the user removes the pressing force. In an optional embodiment, the elastic reset member is a spring. Preferably, the elastic reset member is a torsion spring.

[0082] In this specification, it should be understood that the operation portion S400 and the operation assembly 300 are separated from each other on two sides in the width direction of the safety seat (or the safety seat base), as shown in FIGS. 32 and 41. The operation portion S400 and the operation assembly 300 may each have two operating members. In this case, one operating member of the operation assembly 300, for example, the first operating member S410a, may be disposed on one side of the safety seat (or the safety seat base), and the other operating member of the operation assembly 300, for example, the second operating member S410b, may be disposed on the other side of the safety seat (or the safety seat base). In some embodiments, the operation portion S400 and the operation assembly 300 can each have one operating member. In this case, the operating member of the operation portion S400 and the operating member of the operation assembly 300 may be disposed on one side of the safety seat (or the safety seat base), or may be respectively disposed on two sides of the safety seat (or the safety seat base). The specific arrangements of the operation portion S400 and the operation assembly 300 are not limited thereto, and may be adaptively adjusted as necessary as long as the operation portion S400 and the operation assembly 300 can achieve their respective functions as described above.

[0083] In some embodiments, referring to FIGS. 41 and 44, the adjustment assembly S300 further includes two tension members S700. Each of the tension members S700 includes one of a steel rope, an iron rope, a plastic tension rope, a tension rope made of a polymer material, and a rope made of an organic fiber, or a combination thereof. The first operating member S410a and the second operating member S410b are respectively connected to the two engaging members S310 via the two tension members S700. Due to the tension effect of the tension members S700, when the first operating member S410a and the second operating member S410b pivot between the reset position and the pressing position, they can drive the corresponding engaging members S310 to move in a direction to release the slide rod assembly S200 from the support portion S100 or in a direction to lock the slide rod assembly S200 to the support portion S100.

[0084] In some embodiments, referring to FIG. 45, each of the first operating member S410a and the second operating member S410b includes an operating end S411 and a tension end S412 connected to a corresponding tension member S700. The operating end S411 and the tension end S412 are disposed at two opposite ends of the operating member S410 with respect to the pivot axis S413, respectively. The operating end S411 is configured to provide the user with a convenient force application point for the user to press the first operating member S410a and the second operating member S410b. By the operating end S411 and the tension end S412 being disposed at two opposite ends of the operating member S410 with respect to the pivot axis S413, when the user presses the operating end S411, the tension end S412 can be driven to pivot. The tension end S412 drives the tension member S700 connected to the tension end S412 to move, and drives the engagement member S310 to move by the tension effect of the tension member S700.

[0085] In this embodiment, the operating member S410 and the engaging member S310 connected to each tension member S700 are positioned on two opposite sides of the connecting portion S320, respectively. As shown in FIG. 44, for example, one tension member S700 is connected to the first operating member S410a and the first engaging member S310a, and the other tension member S700 is connected to the second operating member S410b and the second engaging member S310b. Therefore, when the operating end S411 of the first operating member S410a is pressed, the tension member S700 drives the first engaging member S310a and moves it toward the connecting portion S320. The movement of the first engaging member S310a can drive the connecting portion S320 to synchronously drive the second engaging member S310b and move it toward the connecting portion S320. In other words, in this embodiment, when the first operating member S410a is pressed, the first engaging member S310a and the second engaging member S310b are driven to approach each other via the tension member S700 and the connecting mechanism S320, and the lock between the support portion S100 and the slide rod assembly S200 can be released. Similarly, the same result can be achieved when the second operating member S410b is pressed, and thus the details thereof will not be described again here.

[0086] In some other embodiments, the operating end S411 and the tension end S412 may also be arranged at the same end of the operating member S410 with respect to the pivot axis S413 as long as the tension end S412 is driven to pivot when the user presses the operating end S411, and then the tension member S700 connected to the tension end S412 is driven to move.

[0087] In some embodiments, referring to FIG. 46, the adjustment assembly S300 further includes two steering struts S800. The two steering struts S800 correspond one-to-one with the two tension members S700. Each of the two tension members S700 is disposed around the corresponding steering strut S800 and changes the tension direction of the tension member S700. In different embodiments, referring to FIGS. 46 and 47, the positions of the first operating member S410a and the second operating member S410b with respect to the corresponding engaging member S310 may be different. Since the steering strut S800 is arranged to change the tension direction of the tension member S700, even in different arrangements, the first operating member S410a or the second operating member S410b can drive the corresponding engaging member S310 to move in a desired direction.

[0088] Furthermore, in the embodiment of FIG. 46, both the first operating member S410a and the first engaging member S310a are positioned on one side of the connecting portion S320. That is, the first engaging member S310a is closer to the first operating member S410a. In addition, both the second operating member S410b and the second engaging member S310b are positioned on the other side of the connecting portion S320. That is, the second engaging member S310b is closer to the second operating member S410b.

[0089] Specifically, referring to FIGS. 46 and 47, in some embodiments, the first operating member S410a, the second operating member S410b, and the two engaging members S310 are spaced apart along the width direction of the safety seat. The first operating member S410a and the second operating member S410b are respectively disposed at the two mounting ports S2012. The two engaging members S310 (the first engaging member S310a and the second engaging member S310b) are disposed within the mounting cavity S2011. The support portion S100 includes a first mounting rack S110a and a second mounting rack S110b. The first mounting rack S110a is releasably locked to the first slide rod S210a, and the second mounting rack S110b is releasably locked to the second slide rod S210b. The first slide rod S210a and the first mounting rack S110a are disposed between the first operating member S410a and the first engaging member S310a. The second slide rod S210b and the second mounting rack S110b are disposed between the second operating member S410b and the second engaging member S310b.

[0090] In one embodiment, referring to FIG. 46, the first operating member S410a is connected via a tension member S700 to a first engaging member S310a adjacent to one side where the first operating member S410a is disposed. The second operating member S410b is connected via a tension member S700 to a second engaging member S310b adjacent to one side where the second operating member S410b is disposed. In this case, the adjustment assembly S300 is provided with a steering column S800. Thus, when the first operating member S410a pivots from the reset position to the pressing position, the tension end portion S412 of the first operating member S410a moves in a direction away from the second operating member S410b, and the tension end portion S412 of the first operating member S410a drives the tension member S700 to move in a direction away from the second operating member S410b. Since the tension direction of the tension member S700 can be changed due to the presence of the steering column S800, the tension member S700 drives the first engaging member S310a to move closer to the second operating member S410b and away from the first operating member S410a, thereby driving the first engaging member S310a to move in a direction away from the first slide rod S210a and the first mounting rack S110a. Therefore, since the first engaging member S310a can be disengaged from the first slide rod S210a and the first mounting rack S110a, the first slide rod S210a can be released from the first mounting rack S110a. On the other hand, the connecting portion S320 enables the second engaging member S310b to move synchronously in a direction away from the second operating member S410b, so that the second engaging member S310b can be disengaged from the second slide rod S210b and the second mounting rack S110b, thereby releasing the second slide rod S210b from the second mounting rack S110b and realizing the unlocking between the support portion S100 and the slide rod assembly S200. As can be understood, the steering column S800 is arranged to control the tension direction of the tension member S700, so that even with different arrangements, the first operating member S410a or the second operating member S410b can drive the corresponding engaging member S310 to move in a desired direction.

[0091] In another embodiment, referring to FIG. 47, the first operating member S410a is connected to a second engaging member S310b adjacent to one side where the second operating member S410b is disposed via a tension member S700. The second operating member S410b is connected to a first engaging member S310a adjacent to one side where the first operating member S410a is disposed via a tension member S700. In this case, the adjustment assembly S300 is not provided with a steering column S800. Thus, when the first operating member S410a pivots from the reset position to the pressing position, the tension end portion S412 of the first operating member S410a moves in a direction away from the second operating member S410b, so that the tension member S700 drives the second engaging member S310b and moves it in a direction away from the second operating member S410b. That is, the second engaging member S310b moves in a direction away from the second slide rod S210b and the second mounting rack S110b, disengaging the second engaging member S310b from the second slide rod S210b and the second mounting rack S110b, and releasing the second slide rod S210b from the second mounting rack S110b. On the other hand, the connecting portion S320 enables the first engaging member S310a to move synchronously in a direction away from the first operating member S410a, so that the first engaging member S310a can be disengaged from the first slide rod S210a and the first mounting rack S110a, and the first slide rod S210a can be released from the first mounting rack S110a, thereby realizing the unlocking between the support portion S100 and the slide rod assembly S200.

[0092] In some embodiments, referring to FIGS. 42 and 44, the adjustment assembly S300 further includes two rolling members S900. The two tension members S700 are respectively disposed on the two rolling members S900. Thus, when the tension member S700 moves, the tension member S700 drives the rolling member S900 to roll by friction. Due to the synchronous rolling effect between the rolling member S900 and the tension member S700, the movement of the tension member S700 can be made smoother. The rolling member S900 includes a roller. The rolling member S900 is rotatably disposed on the base lower cover S201.

[0093] In some embodiments, referring to FIGS. 44, 46, and 47, the connecting portion S320 is rotatably disposed, and the extending direction of the rotating shaft of the connecting portion S320 is different from the moving direction of the slide rod S210 and also different from the moving directions of the two engaging members S310. In this embodiment, the moving direction of the slide rod S210 is substantially parallel to the length direction L of the safety seat (or the safety seat base 1), and the moving directions of the two engaging members S310 are substantially parallel to the width direction W of the safety seat (or the safety seat base 1). In addition, in this embodiment, the two engaging members S310 and the connecting portion S320 are mainly driven by meshing, but the present application is not limited thereto. In other embodiments, the two engaging members S310 and the connecting portion S320 may also be connected to each other by other transmission methods.

[0094] In this embodiment, each of the two engaging members S310 is provided with a first meshing portion S311, and around the connecting portion S320, a second meshing portion S321 that fits the first meshing portion S311 is provided. Each of the two engaging members S310 is movably connected to the connecting portion S320 by the meshing of its respective first meshing portion S311 with the second meshing portion S321. In this way, when one of the two engaging members S310 is driven by the operating portion S400 to move, the first meshing portion S311 of this engaging member S310 moves, and the connecting portion S320 is driven to rotate by the mutual meshing between the first meshing portion S311 and the second meshing portion S321. While rotating, the connecting portion S320 drives the first meshing portion S311 of the other of the two engaging members S310, and moves it by the mutual meshing between the second meshing portion S321 and the first meshing portion S311 of the other of the two engaging members S310, thereby driving the other of the two engaging members S310 to move, and thereby realizing the synchronous movement of the two engaging members S310. Specifically, the first meshing portion S311 is a rack, the connecting portion S320 is a gear, and the second meshing portion S321 is the teeth of the gear. In an optional embodiment, the connecting portion S320 is rotatably connected to the base lower cover S201.

[0095] Specifically, referring to FIGS. 46 and 47, the two first meshing portions S311 of the two engaging members S310 are respectively positioned on two opposite sides of the connecting portion S320 and are meshing with the second meshing portion S321. The first meshing portions S311 and the connecting portion S320 of the two engaging members S310 are respectively positioned between the first slide rod S210a and the first mounting rack S110a, and between the second slide rod S210b and the second mounting rack S110b. The first engaging member S310a is positioned on the side adjacent to the first slide rod S210a and the first mounting rack S110a. The first engaging member S310a is configured to releasably lock the first slide rod S210a to the first mounting rack S110a. The second engaging member S310b is positioned on the side adjacent to the second slide rod S210b and the second mounting rack S110b. The second engaging member S310b is configured to releasably lock the second slide rod S210b to the second mounting rack S110b.

[0096] In this way, when the first engaging member S310a moves in a direction approaching the first slide rod S210a and the first mounting rack S110a to lock the first slide rod S210a to the first mounting rack S110a, the mutual engagement between the first engaging portion S311 of the first engaging member S310a and the second engaging portion S321 of the connecting portion S320, the rotation of the connecting portion S320, and the mutual engagement between the second engaging portion S321 and the first engaging portion S311 of the second engaging member S310b drive the second engaging member S310b to move in a direction approaching the second slide rod S210b and the second mounting rack S110b, and the second slide rod S210b can be locked to the second mounting rack S110b. When the first engaging member S310a moves in a direction away from the first slide rod S210a and the first mounting rack S110a to release the first slide rod S210a from the first mounting rack S110a, the mutual engagement between the first engaging portion S311 of the first engaging member S310a and the second engaging portion S321, the rotation of the connecting portion S320, and the mutual engagement between the second engaging portion S321 and the first engaging portion S311 of the second engaging member S310b drive the second engaging member S310b to move in a direction away from the second slide rod S210b and the second mounting rack S110b, and the second slide rod S210b can be released from the second mounting rack S110b.

[0097] Similarly, when the second engagement member S310b moves in a direction approaching the second slide rod S210b and the second mounting rack S110b to lock the second slide rod S210b to the second mounting rack S110b, the mutual engagement between the first meshing portion S311 and the second meshing portion S321 of the second engagement member S310b, the rotation of the connecting portion S320, and the mutual engagement between the second meshing portion S321 and the first meshing portion S311 of the first engagement member S310a drive the first engagement member S310a to move in a direction approaching the first slide rod S210a and the first mounting rack S110a, and lock the first slide rod S210a to the first mounting rack S110a. When the second engagement member S310b moves in a direction away from the second slide rod S210b and the second mounting rack S110b to release the second slide rod S210b from the second mounting rack S110b, the mutual engagement between the first meshing portion S311 and the second meshing portion S321 of the second engagement member S310b, the rotation of the connecting portion S320, and the mutual engagement between the second meshing portion S321 and the first meshing portion S311 of the first engagement member S310a drive the first engagement member S310a to move in a direction away from the first slide rod S210a and the first mounting rack S110a, and release the first slide rod S210a from the first mounting rack S110a. Therefore, driven by one of the two engagement members S310, the other of the two engagement members S310 can be driven by the connecting portion S320 to move, so that the two engagement members S310 move synchronously to lock the slide rod assembly S200 to the support portion S100 or release the slide rod assembly S200 from the support portion S100.

[0098] In some embodiments, referring to FIG. 44, the two engagement members S310 each correspond to two slide rods S210. Each of the two engagement members S310 (i.e., the first engagement member S310a and the second engagement member S310b) is provided with an engagement portion S312, and the engagement portion S312 is configured to releasably engage with the corresponding slide rod S210 and the support portion S100. Thus, the engagement member S310 releasably engages with the corresponding slide rod S210 and the support portion S100 through the engagement portion S312, thereby releasably locking the slide rod assembly S200 to the support portion S100. The engagement portion S312 and the engagement member S310 may be integrally formed or may be two separate parts connected to each other.

[0099] Specifically, referring to FIG. 44, the engaging portion S312 includes engaging pins, and the support portion S100 is provided with first engaging holes S111 corresponding to the two engaging members S310. Optionally, the two first engaging holes S111 are respectively provided in the two mounting racks S110. Referring to FIGS. 43 and 44, each of the two slide rods S210 is provided with a plurality of second engaging holes S211. All the second engaging holes S211 provided in each slide rod S210 may be spaced apart from each other along the length direction of the safety seat (for example, the direction L in FIG. 43). The engaging pin is adapted to penetrate through the corresponding first engaging hole S111 and be inserted into one of the second engaging holes S211 of the corresponding slide rod S210 so as to releasably lock the corresponding slide rod S210 to the support portion S100. In addition, since each of the two slide rods S210 is provided with a plurality of second engaging holes S211, the engaging pin can be selectively inserted into one of the second engaging holes S211, and the support portion S100 is connected to different positions of the slide rod assembly S200. Then, the relative position between the safety seat base 1 and the ISOFIX connector S2 becomes variable so as to adjust the length of the ISOFIX connector S2 protruding from the safety seat base 1. Referring to FIGS. 48 and 49, the change in the relative position between the ISOFIX connector S2 and the safety seat base 1 can be understood. According to the adjustment mechanism S10 of the embodiment of the present application, the relative positions of the two ISOFIX connectors S2 and the safety seat base 1 arranged in the width direction W of the safety seat base 1 can be synchronously adjusted, thereby adjusting the length of the ISOFIX connector S2 protruding from the outer surface of the safety seat base 1. The adjustment mechanism S10 according to the embodiment of the present application has a simple structure, is easy to use, and can reduce costs.

[0100] According to one aspect of the present disclosure, a safety seat base is provided. A safety seat body is attached to the safety seat base. The safety seat base includes a mounting base, a rotating plate rotatably disposed on the mounting base and having a first rotation position and a second rotation position, an engaging mechanism configured to engage the rotating plate with the safety seat body, and a connecting mechanism. The connecting mechanism includes a driving member slidably disposed on the mounting base and a sliding member slidably disposed on the rotating plate. The sliding member at least partially protrudes into the mounting base and abuts against the driving member, or the driving member at least partially protrudes into the rotating plate and abuts against the sliding member. When the rotating plate rotates to the first rotation position, the driving member is operable to move and drive the sliding member to slide so as to drive the engaging mechanism to unlock.

[0101] In the above safety seat base, when the rotating plate rotates to the first rotation position with respect to the mounting base (for example, when it is in the rear-facing state), the driving member in the connecting mechanism becomes operable. Since the slide member at least partially protrudes into the mounting base and is drivably connected to the driving member, or the driving member at least partially protrudes into the rotating plate and is drivably connected to the slide member, the driving member can directly drive and move the slide member while moving the slide member so as to drive the engaging mechanism to release the lock. In this case, the safety seat base is disengaged from the safety seat body, and the safety seat body can be removed from the safety seat base. However, when the rotating plate rotates to the second rotation position with respect to the mounting base (for example, until it is in the forward-facing state), even if the driving member is operated and moved, since the driving member does not contact the slide member, the engaging mechanism remains locked, the safety seat base and the safety seat body remain engaged, and the safety seat body cannot be disassembled from the safety seat base. With this configuration, after the child safety seat in the second rotation position (for example, the forward-facing state) is removed, when the user engages the infant safety seat with the safety seat base, misuse caused by the infant safety seat being in the forward-facing state can be prevented, thereby improving the safety rate.
