Description

Leg rest structure, child safety seat and storage mechanism Technical Field

[0001] This application relates to the field of infant and toddler products technology, and in particular to a leg rest structure, a car seat, and a storage mechanism. Background Technology

[0002] Child safety seats, also known as Child Restraint Systems (CRS), are seats specifically designed for children and installed inside cars to effectively improve children's safety while traveling. To enhance comfort, leg rests are typically added to these seats. However, most current leg rests are not adjustable, limiting the seat's ability to accommodate a wider range of seating needs and thus reducing the child's overall comfort.

[0003] In addition, child safety seats often include storage mechanisms, such as cup holders and shelves, to conveniently hold items like water cups, bottles, and snacks. However, these mechanisms are usually fixed in place and cannot be removed, thus encroaching on the user's seating space and reducing the user experience. Furthermore, because different child safety seat storage mechanisms can interfere with each other, it is impossible to install multiple child safety seats side by side in the same row of vehicles. Moreover, when switching between different usage modes, such as from upright to reclined, the storage mechanisms tilt with the child safety seat, which may cause liquids from water cups to spill, further inconveniencing the user.

The seat reinforcement 240b extends along the front-to-back direction of the seat body 200, while the back reinforcement 240a extends along the height direction of the seat body 200. With a child normally seated on the seat body 200 as a reference, the child's face is facing forward of the seat body 200.

[0104] It should be noted that in this embodiment, the reinforcing member 240 can be, for example, a reinforcing tube, which has a hollow structure. Of course, in other embodiments, the reinforcing member 240 can also be, for example, a reinforcing rod, which has a solid structure; no specific limitation is made here.

[0105] In one embodiment, the backrest reinforcement 240a and the seat reinforcement 240b are a single component, i.e., they are integrally formed. Of course, in other embodiments, the backrest reinforcement 240a and the seat reinforcement 240b can also be two independent components, connected by means such as welding, bonding, or snap-fitting; no specific limitation is made here. Optionally, the number of reinforcements 240 can be one, two, or three, etc., without specific limitation. In this embodiment, as shown in Figures 1 and 2, two reinforcements 240 are provided, arranged on the left and right sides of the seat body 200. This enhances the strength of the seat body 200, thereby increasing its service life. A groove 251 is provided on the surface of the seat body 200 facing the seating space 230, which is used to accommodate the reinforcements 240. When the reinforcing member 240 is placed in the groove 251, the reinforcing member 240 may be flush with the surface of the seat body 200 facing the seating space 230, or lower than the surface of the seat body 200 facing the seating space 230, or protrude from the surface of the seat body 200 facing the seating space 230, without any specific limitation.

[0106] It should be noted that, in order to intuitively understand the fore-and-aft direction of the safety seat 1000 and the seat body 200, arrows F and B are used to schematically indicate the "fore" and "rear" directions in the accompanying drawings, respectively. These directional terms are only used to make the description of the embodiments of the present invention clearer and are not intended to unduly limit the scope of protection of the present invention.

[0107] Referring to Figures 1 to 3, in one embodiment, the leg rest structure 100 is primarily used for mounting to the seat body 200. When a child sits in the seating space 230 of the seat body 200, the leg rest structure 100 can support the child's legs and feet (specifically, the lower legs and feet), thus improving the child's seating comfort. In one embodiment, the leg rest structure 100 may include, for example, a leg rest member 110 and a locking mechanism 120. The leg rest member 110 is mounted on the seat body 200 and is movable relative to the seat body 200, thus changing the length of the leg rest member 110 extending relative to the seat body 200. The locking mechanism 120 is provided on the leg rest member 110 and selectively engages with one of a plurality of locking parts 241 on the seat body 200, thus fixing the leg rest member 110 relative to the seat body 200 at the desired extension length position. More specifically, in this embodiment, the leg rest 110 is slidably mounted to the seat portion 210, and the leg rest 110 can extend or retract relative to the front end of the seat portion 210 (i.e., the end away from the backrest portion 220). When the leg rest 110 slides relative to the seat portion 210 and extends from the front end of the seat portion 210, the length of the seat portion 210 along the front-rear direction of the seat body 200 can be considered to have increased (specifically, the increased portion is the portion of the leg rest 110 that extends relative to the front end of the seat portion 210). In this way, necessary support can be provided for the child's lower legs and feet that were originally dangling at the front end of the seat portion 210, thereby improving the comfort of the child's seating.

[0108] In one embodiment, the leg rest 110 has an extended state (see Figures 2 and 4) and a retracted state (see Figures 1 and 3), and the leg rest 110 can switch between these two states. Specifically, the leg rest 110 extends further beyond the seat body 200 in the extended state than in the retracted state. In simpler terms, when the leg rest 110 is in the extended state, its extension length relative to the front end of the seat portion 210 is L1 (see Figure 4); when the leg rest 110 is in the retracted state, its extension length relative to the front end of the seat portion 210 is L2 (see Figure 3), where L2 ≥ 0 and L1 > L2. It should be noted that in this embodiment, the specific value of L1 is not fixed. In other words, the extension length of the leg rest 110 relative to the front end of the seat portion 210 is adjustable, specifically, it can be adjusted according to the user's actual needs. Therefore, regardless of the value of L1, as long as the extension length of the leg rest 110 is greater than L2, the leg rest 110 can be considered to be in the extended state. Of course, in other embodiments, the specific value of L1 can also be fixed, that is, when the leg rest 110 is in the extended state, its extension length relative to the front end of the seat 210 is fixed, and no specific limitation is made here. When it is necessary to support the child's lower legs and / or feet in an elevated state, the user can adjust the leg rest structure 100 to make the leg rest 110 extend. In narrower carriages, due to space limitations, the leg rest structure 100 can be adjusted to make the leg rest 110 retracted; or, according to the child's needs, the leg rest 110 can be adjusted to the retracted state.

[0109] Referring to Figures 3 to 6, in one embodiment, the leg rest 110 may include, for example, a leg rest plate 111 and a slider 112, wherein the leg rest plate 111 is mounted on the slider 112, and the slider 112 is slidably connected to the reinforcement 240 (specifically, the seat reinforcement 240b). It should be noted that the slider 112 may be, for example, a sliding tube with a hollow structure; or, the slider 112 may be a sliding rod with a solid structure. Specifically, in this embodiment, both the reinforcement 240 and the slider 112 are hollow structures, and they are slidably connected. Specifically, when the slider 112 slides relative to the seat reinforcement 240b, the slider 112 causes the leg rest plate 111 to slide relative to the seat body 200 to change the length of the leg rest plate 111 extending relative to the seat body 200. Specifically, when the leg rest 110 is in the extended state, the leg rest plate 111 is mainly used to support the child's lower legs and / or feet. Along the front-rear direction of the seat body 200, the end of the leg rest 111 closest to the backrest 220 is referred to as the first end 111a, and the end of the leg rest 111 furthest from the backrest 220 is referred to as the second end 111b; in other words, the first end 111a and the second end 111b of the leg rest 111 are arranged opposite to each other along the front-rear direction of the seat body 200. Based on this, the aforementioned "extension length of the leg rest 110 relative to the front end of the seat 210" can also be understood as the distance of the second end 111b of the leg rest 111 from the front end of the seat 210. In this embodiment, the leg rest 110 includes two sliding members 112, which are slidably connected (specifically, slidably sleeved) to the two aforementioned seat reinforcement members 240b, and the leg rest 111 is connected between the two sliding members 112. This improves the stability of the leg rest 110 during sliding and also increases the structural strength of the leg rest 110, preventing deformation of the leg rest 111 during support. In one embodiment, the leg rest plate 111 can be installed on the sliding member 112 by bolts, screws, etc. Of course, the leg rest plate 111 can also be installed on the sliding member 112 by welding, bonding, etc., and no specific limitation is made here.

[0110] It should be noted that the "sliding connection between the sliding member 112 and the reinforcing member 240" includes two implementation methods: first, the sliding member 112 is sleeved outside the reinforcing member 240 to achieve relative sliding between the two; second, the sliding member 112 is inserted inside the reinforcing member 240 to achieve relative sliding between the two. Specifically, in this embodiment, the sliding member 112 is inserted inside the reinforcing member 240, that is, the reinforcing member 240 is sleeved outside the sliding member 112.

[0111] Please refer to Figures 3 through 6. In one embodiment, the surface of the seat portion 210 facing the seating space 230 has an arc-shaped surface 211. The reinforcing members 240 and sliding members 112 located on the left and right sides of the seat portion 210 both adopt an arc-shaped design. Correspondingly, the leg rest 111 is an arc-shaped plate that curves towards the seat portion 210, and the curvature of the arc-shaped plate matches the curvature of the arc-shaped surface 211. When the leg rest 110 is in the retracted state, the leg rest 111 can closely conform to the arc-shaped surface 211 of the seat portion 210. This design allows the leg rest 111 to be properly stored when not in use, thereby reducing interference with children and improving the comfort of the seat body 200.

[0112] Referring to Figures 3 and 4, in one embodiment, the seat reinforcement 240b is provided with a plurality of locking portions 241. The locking mechanism 120 includes a locking member 121, which is movably disposed on the slider 112 and has a locked position and an unlocked position. Specifically, as shown in Figures 3 and 4, when the locking member 121 is in the locked position, the locking member 121 inserts into the locking portion 241 to lock and engage with the locking portion 241, thereby restricting the slider 112 from sliding relative to the seat reinforcement 240b. In this way, the leg rest 110 can be fixed relative to the seat portion 210, preventing the two from sliding relative to each other. Thus, the leg rest 110 can be fixed in a retracted state or an extended state. As shown in Figure 7, when the locking member 121 is in the unlocked position, it retracts from the locking part 241 to release the lock on the locking part 241, allowing the sliding member 112 to slide relative to the seat reinforcement 240b. This allows the leg rest 110 to switch between a retracted state and an extended state, and allows adjustment of the extension length of the leg rest 110 relative to the seat part 210. In this embodiment, multiple locking parts 241 are provided, and each locking part 241 can be, for example, a lock hole, with multiple lock holes spaced apart along the length direction of the seat reinforcement 240b. When the locking member 121 is in the locked position, it is inserted into the lock hole, and the sliding member 112 is restricted from sliding relative to the seat reinforcement 240b. When the locking member 121 is in the unlocked position, it retracts from the lock hole, and the sliding member 112 is allowed to slide relative to the seat reinforcement 240b. When the locking member 121 engages with different locking parts 241, the extension length of the leg rest 111 relative to the front end of the seat part 210 will change accordingly. The more locking parts 241 there are, the more adjustment gradients the extension length of the leg rest 111 has, thereby improving the adaptability of the leg rest 111.

[0113] It should be noted that the aforementioned "locking member 121 is movably disposed on sliding member 112" includes, but is not limited to, the following two methods: the locking member 121 is pivotally connected to the sliding member 112; or, the locking member 121 is slidably disposed on the sliding member 112. In other words, the locking member 121 may, for example, be pivotally connected to the sliding member 112 to be able to switch between a locked position and an unlocked position; or, the locking member 121 may also be slidably disposed on the sliding member 112 to be able to switch between a locked position and an unlocked position.

[0114] Referring to Figures 3 and 4, in this embodiment, the locking portion 241 on the seat reinforcement 240b furthest from the front end of the seat portion 210 is referred to as the first locking portion 241a, and the locking portion 241 on the seat reinforcement 240b closest to the front end of the seat portion 210 is referred to as the second locking portion 241b. When the locking member 121 is locked with the first locking portion 241a, the leg rest 110 remains in the retracted state; while when the locking member 121 is locked with the second locking portion 241b, the leg rest 110 is in the extended state at its maximum extension length, that is, at this time the extension length of the leg rest 110 relative to the front end of the seat portion 210 reaches its maximum value.

[0115] Referring to Figures 4, 7, and 8, in this embodiment, a mounting base 113 is provided within the slider 112, and the locking member 121 is pivotally connected to the mounting base 113 to switch between a locked position and an unlocked position. Specifically, the mounting base 113 is located at the end of the slider 112, and the locking member 121 can extend out of the slider 112 through a tube opening at the end of the slider 112 to be inserted into the locking part 241. Of course, in other embodiments, the mounting base 113 may also be located at other positions on the slider 112 besides the end, and the locking member 121 may extend out of the slider 112 through a hole provided in the slider 112; no specific limitation is made here.

[0116] Referring to Figures 4, 7, and 8, in one embodiment, the locking member 121 includes a pivot portion 1211 and a locking hook portion 1212 connected together. The pivot portion 1211 is rotatably disposed on the sliding member 112, and the locking hook portion 1212 is used for locking engagement with the locking part 241. In this embodiment, the pivot portion 1211 is pivotally connected to the mounting base 113, allowing it to rotate relative to the sliding member 112. Specifically, the mounting base 113 has a columnar structure, specifically a cylindrical structure, and its diameter is adapted to the inner diameter of the sliding member 112. This allows direct insertion into and engagement with the sliding member 112, quickly completing the connection between the mounting base 113 and the sliding member 112. In this embodiment, a mounting cavity 1131 is formed inside the mounting base 113. The locking member 121 is installed in the mounting cavity 1131 and connected to the mounting base 113 via a first pin 114 passing through a pivot part 1211. The locking member 121 is rotatable around the first pin 114. Specifically, one end of the mounting base 113 is provided with a through hole 1132 communicating with the mounting cavity 1131. The locking hook part 1212 of the locking member 121 passes through the through hole 1132 to extend out of the mounting base 113 and the sliding member 112 and lock into the locking part 241.

[0117] In one embodiment, the locking mechanism 120 further includes a first reset member 122 (see FIG. 8). The first reset member 122 may be an elastic element such as a spring or torsion spring, which abuts against the locking member 121 to provide an elastic restoring force to the locking member 121, so that the locking member 121 is held in the locked position. Specifically, the first reset member 122 is a torsion spring, which is sleeved outside the first pin 114 and abuts against the mounting base 113 and the locking member 121, so that the locking member 121 can automatically reset to the locked position. Therefore, when the locking hook portion 1212 is opposite to any of the locking portions 241 (i.e., the lock hole), under the restoring force of the first reset member 122, the locking member 121 can be pivoted so that the locking hook portion 1212 can automatically insert into the locking portion 241 to lock and engage.

[0118] To facilitate user control of the position of the locking member 121, in other words, to facilitate user release of the locking member 121, in one embodiment, the leg rest structure 100 further includes a first release mechanism 130. This first release mechanism 130 is movably mounted on the leg rest member 110 and operably connected to the locking member 121, allowing the locking member 121 to switch from a locked position to an unlocked position. Referring again to Figures 4 to 7, specifically, the first release mechanism 130 includes a first drive member 131, a first operating member 132, and a first traction member 133. The first drive member 131 is movably disposed within the sliding member 112, specifically on a mounting base 113 movably disposed within the sliding member 112, and has a first position and a second position. The first drive member 131 engages in a driving cooperation with the locking member 121. When the first driving member 131 switches from the first position to the second position, it pushes against the locking member 121, causing the locking member 121 to switch from the locked position to the unlocked position (switching from Figure 4 to Figure 7). More specifically, the first operating member 132 is operably disposed on the leg rest member 110, and the first traction member 133 is connected between the first operating member 132 and the first driving member 131. When the first operating member 132 is operated, it can drive the first driving member 131 to switch from the first position to the second position via the first traction member 133, thereby causing the locking member 121 to switch from the locked position to the unlocked position. Therefore, when the user needs to unlock the locking member 121, they only need to operate (e.g., press) the first operating member 132. In this embodiment, the moving direction (specifically the sliding direction) of the first operating member 132 can be approximately perpendicular to the leg rest member 110, i.e., the leg rest plate 111 or the sliding member 112. It has an initial position and a pressing position. When the first operating member 132 switches from the initial position to the pressing position, the first driving member 131 can switch from the first position to the second position through the transmission of the first traction member 133.

[0119] Referring to Figures 6, 9, and 10, in one embodiment, the second end 111b of the leg rest 111 is provided with a mounting step 115. This mounting step 115 is generally vertical and protrudes from the side of the leg rest 111 facing the ground, and a mounting through hole 1151 is provided within the mounting step 115. The first operating member 132 is movably disposed within the mounting through hole 1151. To prevent the first operating member 132 from falling out of the mounting through hole 1151 and detaching from the leg rest 110 during the switching process from the initial position to the pressing position, a limiting member 116 is provided at the bottom of the mounting through hole 1151, and a limiting cavity 1161 is provided within the limiting member 116. Specifically, the first release mechanism 130 also includes a third reset member 134. The first operating member 132 has a connected pressing head 1321 and a push rod 1322. The push rod 1322 can be inserted into the limiting cavity 1161 and move up and down within the limiting cavity 1161. The pressing head 1321 is adapted to be pressed, and its size is larger than the size of the limiting cavity 1161. The third reset member 134 can be an elastic element such as a spring or a spring sheet, which is used to abut against the first operating member 132 to provide elastic restoring force for the first operating member 132. Specifically, the third reset member 134 is a spring, which is sleeved outside the push rod 1322 and abuts against the pressing head 1321 and the limiting member 116. When the pressing head 1321 is pressed to switch the first operating member 132 to the pressing position, the push rod 1322 gradually inserts into the limiting cavity 1161, and the spring is compressed. When the user releases the pressing head 1321, the spring returns to its original position to push the first operating member 132 back to its initial position. Of course, in other embodiments, the direction of movement of the first operating member 132 may also be parallel to the leg rest plate 111 or the sliding member 112, and no specific limitation is made here.

[0120] It should be noted that, since the mounting step 115 protrudes from the side of the leg rest 111 facing the ground, the leg rest is approximately in contact with the upper surface of the seat portion 210 (i.e., the side facing the seating space 230). Therefore, when the leg rest 110 is in the retracted state, the mounting step 115 will abut against the front end of the seat portion 210.

[0121] Please refer again to Figures 4 and 7. In one embodiment, the locking member 121 further includes a pushing portion 1213, which is disposed on the side of the pivot portion 512 opposite to the hook portion 1212. In other words, the pivot portion 512 can be considered as connecting the hook portion 1212 and the pushing portion 1213. The first driving member 131 is provided with a driving ramp 1311, which is adapted to abut against the pushing portion 1213. Specifically, the driving ramp 1311 extends obliquely relative to the moving direction of the first driving member 131. When the first driving member 131 switches from the first position to the second position, the driving ramp 1311 pushes against the pushing portion 1213, thereby pivoting the locking member 121 to the unlocking position. In this embodiment, the mounting base 113 is provided with a second reset member 135. The second reset member 135 may be an elastic element such as a spring or a sheet, which is used to abut against the first driving member 131 to provide elastic restoring force to the first driving member 131 so that the first driving member 131 is held in the first position. Therefore, when the user releases the first operating member 132, the first operating member 132 can be automatically reset to the initial position under the action of the third reset member 134; at the same time, the first driving member 131 can be automatically reset to the first position under the action of the second reset member 135, and the locking member 121 can be pivoted to the locked position under the action of the first reset member 122.

[0122] In one embodiment, two locking mechanisms 120 are provided, each located within one of the two sliding members 112 to lock or unlock with the corresponding locking portion 241. This enhances the stability of the leg rest 110 locked onto the seat portion 210. In this embodiment, a first unlocking mechanism 130 is provided, comprising two first traction members 133 and two first driving members 131. The two first driving members 131 are respectively driven to engage with the two locking members 121. One end of each of the two first traction members 133 is connected to a first operating member 132, and the other end of each is connected to the two first driving members 131. When the first operating member 132 is operated, both locking members 121 can be unlocked simultaneously, thus improving the ease of unlocking. Of course, in other embodiments, one locking mechanism 120 and one first release mechanism 130 may be provided; or, two locking mechanisms 120 and two first release mechanisms 130 may be provided, with the two first release mechanisms 130 respectively driving and cooperating with the locking elements 121 of the two locking mechanisms 120. No specific limitation is made here.

[0123] It should be noted that in this embodiment, the first operating member 132 is located in the middle of the second end 111b of the leg rest plate 111. This allows for convenient control of the simultaneous release of the two locking members 121 when the first operating member 132 is operated. Since the first operating member 132 is located in the middle, it is not visible in the cross-sectional views along the U1-U1 line or the U2-U2 line (e.g., Figures 3, 4, and 7), but it is visible in the cross-sectional views along the U3-U3 line (e.g., Figures 9 and 10).

[0124] To enhance the comfort of children using the leg rest structure 100 to support their lower legs and / or feet, in one embodiment, the leg rest structure 100 may further include a pad (not shown) that covers the leg rest plate 111 or the side of the leg rest plate 111 that contacts the leg. In this embodiment, as shown in FIG11, the leg rest plate 111 is provided with a connecting portion 117 for connecting the pad. Specifically, the connecting portion 117 may be, for example, one of the loop side and hook side of a pair of Velcro; or one of the zipper teeth and chain teeth of a pair of zippers; or one of the snap fasteners and loops of a pair of snap fasteners. The pad is provided with a mating portion (not shown), which may be, for example, the other of the loop side and hook side of a pair of Velcro; or the other of the zipper teeth and chain teeth of a pair of zippers; or the other of the snap fasteners and loops of a pair of snap fasteners. Specifically, the sleeve and the leg rest 111 are connected by a snap fastener, meaning the sleeve is equipped with snaps, and the leg rest 111 is equipped with corresponding buckles, and the two are connected by snapping together. More specifically, to make the connection more stable and reliable, the sleeve is equipped with multiple snaps, and the leg rest 111 is equipped with multiple buckles, which are spaced apart along the circumference of the leg rest 111.

[0125] The following section, with reference to relevant illustrations, briefly explains the usage process and principle of the leg rest structure 100.

[0126] Referring to Figures 1 and 3, in one embodiment, when the leg rest 110 is in the retracted state, the locking member 121 engages with the first locking portion 241a on the sliding member 112. At this time, the leg rest 111 is in close contact with the upper surface of the seat portion 210. In one embodiment, the leg rest 111 almost completely covers the seat portion 210. This design effectively saves space occupied by the child safety seat 1000 in the vehicle compartment.

[0127] Referring to Figures 3, 4, 7, 9, and 10, when a user needs to use the leg rest structure 100 to support a child's legs, they can first operate (e.g., press) the first operating member 132 to switch it to the pressing position. During this process, the first operating member 132 drives the first traction member 133 to move, thereby causing the first driving member 131 to move from the first position to the second position. Simultaneously, the first driving member 131 pushes against the pushing part 1213 of the locking member 121, causing the locking member 121 to switch from the locked position to the unlocked position, ultimately realizing that the locking hook part 1212 retracts from the first locking part 241a. After unlocking, the user can push or pull the leg rest member 110 to move the sliding member 112 relative to the seat reinforcement member 240b, thereby adjusting the extension length of the leg rest plate 111 relative to the front end of the seat part 210. When the leg rest plate 111 reaches the position desired by the user (at this time, the locking hook part 1212 should be opposite the corresponding locking part 241), the user releases the first operating member 132. The first operating member 132 automatically resets to its initial position under the restoring force of the third reset member 134. At the same time, the first driving member 131 is no longer pulled by the first traction member 133 and automatically resets to the first position under the action of the second reset member 135. At this time, the first driving member 131 separates from the pushing part 1213 of the locking member 121. The locking member 121 is no longer pressed by the driving inclined surface 1311 of the first driving member 131 and automatically pivots to the locked position under the action of the first reset member 122. The locking hook part 1212 is re-inserted into other locking parts 241 except for the first locking part 241a.

[0128] When the user no longer needs the leg rest structure 100, the first operating member 132 can be operated again to switch it back to the pressing position. At this time, the locking member 121 is released, and the leg rest member 110 can move relative to the seat portion 210. Subsequently, the user pushes or pulls the leg rest member 110 to retract it to the upper surface of the seat portion 210. When the locking member 121 moves with the sliding member 112 to be opposite the first locking part 241a, the first operating member 132 is released. Under the action of the reset members (such as the first reset member 122, the second reset member 135, and the third reset member 134), the locking member 121 automatically resets to the locked position, and the locking hook 1212 re-inserts into the first locking part 241a. In this way, the leg rest member 110 can be kept in the retracted state.

[0129] Referring to Figures 12 and 13, in one embodiment, the child safety seat 1000 also includes a safety harness 300 disposed within the seating space 230. When a child is seated on the seat body 200 of the child safety seat 1000, the safety harness 300 can be secured to the child's shoulders, waist, and / or hips, thereby improving the child's safety while seated. Typically, one end of the safety harness 300 (referred to as the connecting end 310) is secured to the seat body 200, while the other end (referred to as the movable end 320) passes through the backrest portion 220 of the seat body 200 to extend into the cavity 252 of the seat body 200. The portion of the safety harness 300 exposed within the seating space 230 is referred to as the effective securing section 330, which is typically directly secured to the child's shoulders, waist, and / or hips. Typically, the movable end 320 is movable, which allows the length of the effective fixing section 330 to be adjusted. Therefore, the safety harness 300 can be adapted to children of different ages and different usage scenarios. For example, the length of the effective fixing section 330 differs when a child is being taken out of the seat body 200 from the length of the effective fixing section 330 when the child is seated. Specifically, as shown in Figures 13 and 14, the car seat 1000 also includes an adjusting webbing 400 and a webbing adjustment mechanism 500, both of which are located on the seat body 200. One end of the adjusting webbing 400 is connected to the movable end 320 of the safety harness 300, and the other end slides through the webbing adjustment mechanism 500. Thus, the length of the effective fixing section 330 in the safety harness 300 can be controlled by adjusting the length of the adjusting webbing 400 on both sides of the webbing adjustment mechanism 500.

[0130] Please refer to Figures 13 and 14. In one embodiment, the webbing adjustment mechanism 500 has a locked state and an unlocked state. When the webbing adjustment mechanism 500 is in the locked state, the adjusting webbing 400 is allowed to be pulled in one direction (the specific principle is explained below). When the webbing adjustment mechanism 500 is in the unlocked state, the adjusting webbing 400 is allowed to be pulled in both directions (the specific principle is explained below). It should be noted that "the adjusting webbing 400 is allowed to be pulled in one direction" means that one end of the adjusting webbing 400 can be pulled, while the other end is restricted from being pulled. "The adjusting webbing 400 is allowed to be pulled in both directions" means that both ends of the adjusting webbing 400 can be pulled.

[0131] Referring to Figures 12 to 14, in one embodiment, the adjusting webbing 400 and the webbing adjusting mechanism 500 are both located in the inner cavity 252 of the seat body 200. This not only prevents children from accidentally touching the webbing adjusting mechanism 500 when sitting on the seat body 200, thus improving safety, but also effectively protects these components from damage, simplifies the appearance of the seat body 200, and makes it more concise and beautiful.

[0132] In this embodiment, the adjusting webbing 400 has a free end (not shown) and a fixed end 410. The fixed end 410 is connected to the movable end 320 of the safety harness 300, while the free end passes through the webbing adjustment mechanism 500 and extends beyond the seat body 200 for easy user operation. Specifically, the adjusting webbing 400 also has a locking portion 420 located between the fixed end 410 and the free end. The section of the adjusting webbing 400 between the fixed end 410 and the locking portion 420 is referred to as the first section 430. When the free end is pulled, the fixed end 410 causes the movable end 320 to move closer to the webbing adjustment mechanism 500. This shortens both the length of the first section 430 and the length of the effective fixed section 330, thereby tightening the safety harness 300. This helps to restrain the child and prevents the child from slipping off due to an excessively long effective fixed section 330, thus losing its safety protection function. Conversely, when the fixed end 410 is pulled, the length of the first section 430 gradually increases, which allows the movable end 320 to be pulled, thus extending the length of the effective fixed section 330. As the length of the effective fixed section 330 increases, it is suitable for older children and also makes it easier for users to quickly remove the child from the seat body 200.

[0133] It should be noted that, in this embodiment, as shown in Figure 11, the leg rest 110 is provided with a through hole 111d, and the free end of the adjusting webbing 400 can pass through the seat body 200 and extend out from the through hole 111d. Specifically, the leg rest 111 is provided with a through hole 111d, and the free end, after passing through the seat body 200, extends out from the through hole 111d to rest on the side of the leg rest 111 facing away from the seat body 200, so as to facilitate direct operation by the user. When the leg rest 111 slides relative to the reinforcing member 240 of the seat body 200 via the sliding member 112, the free end will also extend outward as the leg rest 111 extends outward, so as to facilitate operation by the user. Of course, in another embodiment, the free end of the adjusting webbing 400 can be directly inserted outside the seat body 200 for user operation.

[0134] Specifically, in this embodiment, when the webbing adjustment mechanism 500 is in the locked state, the free end is allowed to be pulled out, while the fixed end 410 is restricted from being pulled out. When the webbing adjustment mechanism 500 is in the unlocked state, both the free end and the fixed end 410 are allowed to be pulled out. Therefore, before a child sits on the seat body 200, the webbing adjustment mechanism 500 can be unlocked, and the fixed end 410 can be pulled to increase the length of the first section 430. This increases the length of the effective fixed section 330, making it easier for the user to quickly place the child into the seating space 230 covered by the full-body harness 300. It should be noted that since the movable end 320 of the safety harness 300 is connected to the fixed end 410 of the adjusting webbing 400, when it is necessary to increase the length of the effective fixing section 330, with the webbing adjustment mechanism 500 in the unlocked state, the effective fixing section 330 can be pulled directly from the outside of the seat body 200. The movable end 320 will then move the fixed end 410 away from the webbing adjustment mechanism 500. After the child is seated in the seat body 200, tightening the safety harness 300 is considered to shorten the length of the effective fixing section 330, thus confining the child within the seating space 230. At this time, the movable end 320 can be pulled regardless of whether the webbing adjustment mechanism 500 is locked or unlocked. Therefore, the user only needs to pull the movable end 320 outwards.

[0135] Referring to Figures 13 and 14, in one embodiment, the webbing adjustment mechanism 500 includes a locking member 510, which is rotatable relative to the seat body 200 and has a locked position and an unlocked position. When the locking member 510 is in the locked position, it presses against the adjusting webbing 400 to restrict the fixed end 410 from being pulled out while allowing the free end to be pulled out (the specific principle is explained below). When the locking member 510 is in the unlocked position, it releases the pressure on the adjusting webbing 400, allowing both the fixed end 410 and the free end to be pulled out (the specific principle is explained below). Specifically, the webbing adjustment mechanism 500 also includes a mounting bracket 520 disposed within the seat body 200, to which the locking member 510 is pivotally connected to the mounting bracket 520 to pivot relative to the seat body 200. Specifically, the mounting bracket 520 is U-shaped and includes two opposing support plates 521 and a base plate 522 connected between the two support plates 521. A locking member 510 is disposed between two support plates 521 and pivotally connected to the support plates 521 via a second pin 530. A sliding channel 523 is formed between the locking member 510 and the mounting bracket 520 (specifically, the base plate 522), and the adjusting webbing 400 slides through this sliding channel 523. When the locking member 510 is in the locked position, it presses the adjusting webbing 400 against the base plate 522 but allows the adjusting webbing 400 to move in one direction. When the locking member 510 is in the unlocked position, it releases the pressure on the adjusting webbing 400, allowing the adjusting webbing 400 to move bidirectionally within the sliding channel 523.

[0136] Referring again to Figures 13 and 14, in one embodiment, the webbing adjustment mechanism 500 further includes a second drive member 540, which is pivotally connected to the mounting bracket 520 to be rotatable relative to the seat body 200. Specifically, the second drive member 540 has a first linkage 541 (see Figure 15) for pivotal connection with a second pin 530, so that the second drive member 540 and the locking member 510 can pivot about the same pin. In this embodiment, the second drive member 540 pivots and has a third position and a fourth position. When the second drive member 540 pivots from the third position to the fourth position along the first steering direction W1, the second drive member 540 can push the locking member 510 to pivot from the locked position to the unlocked position along the first steering direction W1. Therefore, in this embodiment, the user can indirectly control the locking member 510 by directly controlling the second drive member 540. In this embodiment, the locking member 510 includes a pushing part 511, a pivoting part 512, and a pressing part 513. The pivoting part 512 connects the pushing part 511 and the pressing part 513, and is pivotally connected to the mounting frame 520 via a second pin 530. The second driving member 540 is adapted to engage with the pushing part 511, and the pressing part 513 is adapted to press against the adjusting webbing 400 to restrict the pulling of the fixed end 410. When pivoting, the locking member 510 generally forms a "seesaw" structure; that is, when the pushing part 511 is pressed down or pushed, the pressing part 513 tilts upwards to move away from the bottom plate 522 of the mounting frame 520. This prevents the pressing part 513 from pressing the adjusting webbing 400 firmly against the bottom plate 522 of the mounting frame 520, allowing both ends of the adjusting webbing 400 to be pulled freely.

[0137] In one embodiment, the webbing adjustment mechanism 500 further includes a fourth reset member (not shown) and a fifth reset member (not shown). The fourth and / or fifth reset members can be elastic elements such as springs or torsion springs. The fourth reset member abuts against the locking member 510 to provide an elastic restoring force to the locking member 510, thereby holding the locking member 510 in the locked position. The fifth reset member abuts against the second driving member 540 to provide an elastic restoring force to the second driving member 540, thereby holding the second driving member 540 in a third position. Specifically, in this embodiment, the fourth reset member is a torsion spring, which is sleeved outside the second pin 530 and abuts against the mounting bracket 520 and the locking member 510, so that the locking member 510 can automatically reset to the locked position. The fifth reset member is a torsion spring, which is sleeved outside the second pin 530 and abuts against the mounting bracket 520 and the second driving member 540, so that the second driving member 540 can automatically reset to the third position. Specifically, when the second driving member 540 is not subjected to a force applied by the user, the second driving member 540 can automatically pivot from the fourth position to the third position along the second steering direction W2 under the elastic restoring force of the fifth reset member. During this process, the second driving member 540 releases its pressure on the locking member 510, and the locking member 510 can automatically pivot from the unlocked position to the locked position along the second steering direction W2 under the elastic restoring force of the fourth reset member.

[0138] It should be noted that the first steering direction W1 and the second steering direction W2 are opposite. For example, when the first steering direction W1 is clockwise, the second steering direction W2 is counterclockwise. When the first steering direction W1 is counterclockwise, the second steering direction W2 is clockwise. Furthermore, it should be noted that in this embodiment, when the second drive member 540 pivots along the first steering direction W1 to the fourth position, it is restricted from continuing to pivot along the first steering direction W1. When the second drive member 540 pivots along the second steering direction W2 to the third position, it is restricted from continuing to pivot along the second steering direction W2. In simpler terms, the third and fourth positions are two critical positions within the pivoting range of the second drive member 540. Therefore, when the second drive member 540 is in the third position, the locking member 510 is restricted from continuing to rotate along the second steering direction W2 from the locked position, thereby remaining in the locked position, but is allowed to pivot along the first steering direction W1 from the locked position to the unlocked position. Considering the adjusting webbing 400, even when the webbing adjusting mechanism 500 is in the locked state (i.e., the locking member 510 is in the locked position), when the free end of the adjusting webbing 400 is pulled in one direction, the adjusting webbing 400 can drive the locking member 510 to pivot along the first steering direction W1 towards the unlocked position. However, when the fixed end 410 of the adjusting webbing 400 is pulled in one direction, the locking member 510 is restricted to the locked position due to the obstruction of the second driving member 540. Therefore, when the webbing adjusting mechanism 500 is in the locked state, the free end of the adjusting webbing 400 is allowed to be pulled in one direction, while the fixed end 410 is restricted from being pulled. In this embodiment, as shown in FIG13, the pressing part 513 has an arc-shaped pressing edge, and the arc-shaped pressing edge is provided with a ratchet 5131, which can improve the reliability of the locking member 510 locking the adjusting webbing 400.

[0139] Referring to Figures 13 to 15, in one embodiment, the second driving member 540 includes two opposing support plates 542 and a connecting plate 543 connected between the two support plates 542. The connecting plate 543 has a pressing rib 544 adapted to push against the locking member 510. The two support plates 542 are pivotally connected to two bracket plates 521 respectively via second pins 530. Specifically, the two support plates 542 are located inside the corresponding bracket plates 521, so that the connecting plate 543 can be completely accommodated between the two bracket plates 521 to facilitate the pressing rib 544 pushing against the locking member 510.

[0140] To facilitate user control of the position of the second drive member 540, in one embodiment, the webbing adjustment mechanism 500 further includes a second release mechanism 600. The second release mechanism 600 is operably connected to the second drive member 540, allowing the second drive member 540 to pivot from the third position to the fourth position. Optionally, the second release mechanism 600 can be disposed on the seat body 200 or on the leg rest structure 100 (see Figures 6 and 11), without specific limitations. In this embodiment, the second release mechanism 600 is disposed on the leg rest structure 100. Specifically, as shown in Figures 13 and 14, the second release mechanism 600 includes a second operating member 610 and a second traction member 620. The second operating member 610 is operably disposed on the leg rest structure 100, specifically movably disposed on the leg rest plate 111. The second traction member 620 connects the second operating member 610 and the second drive member 540. When the second operating member 610 is operated (e.g., pulled or pushed), the second operating member 610 drives the second driving member 540 to switch from the third position to the fourth position via the second traction member 620. Specifically, as shown in Figures 13 to 15, the second driving member 540 also has a second linkage part 545, which is provided with a connecting rod 550. The end of the second traction member 620 away from the second operating member 610 is connected to the connecting rod 550. In other words, the second traction member 620 can be indirectly connected to the second linkage part 545 via the connecting rod 550. When the second operating member 610 is operated, the second driving member 540 can be pivoted around the second pin 530 from the third position to the fourth position through the transmission of the second traction member 620. Specifically, the direction of movement of the second operating member 610 can be referenced to the direction of movement of the first operating member 132, for example, perpendicular to or parallel to the leg rest plate 111. In this embodiment, the second operating member 610 moves parallel to the leg rest 111 and has an initial position and an end position. The moving direction of the second operating member 610 is different from the moving direction of the first operating member 132, thus avoiding user misoperation. Specifically, when the second operating member 610 switches from the initial position to the end position, the second driving member 540 can switch from the third position to the fourth position through the transmission of the second traction member 620.

[0141] It should be noted that, in this embodiment, the second operating member 610 is designed to be movably mounted in the middle of the leg rest 111, or between the middle and the second end 111b, or at the second end 111b. This ensures that when a child sits in the seating space 230 and uses the leg rest structure 100, the second operating member 610 is located near the child's feet, facilitating user operation and avoiding inconvenience caused by the second operating member 610 being pressed against the child's legs (e.g., thighs). Furthermore, when the leg rest 111 slides relative to the reinforcement 240 of the seat body 200 via the slider 112, the second operating member 610 also extends outwards along with the extension of the leg rest 111, facilitating user operation. Since the second operating member 610 is disposed on the leg rest 110, the distance between the second operating member 610 and the webbing adjustment mechanism 500 will change as the leg rest 110 moves relative to the seat body 200. Because the second operating member 610 is operably connected to the webbing adjustment mechanism 500 through the second traction member 620, when the leg rest 110 moves relative to the seat body 200, the second operating member 610 can still drive the webbing adjustment mechanism 500 to switch to the unlocked state with the help of the second traction member 620.

[0142] Referring to Figures 16 and 17, in this embodiment, the second operating member 610 is provided with a guide hole 611, which is an oblong hole extending along the moving direction of the second operating member 610. Bolts or screws are inserted into the guide hole 611 to mount the second operating member 610 to the leg rest plate 111. It should be noted that while the bolts or screws can prevent the second operating member 610 from detaching from the leg rest plate 111, they allow the second operating member 610 to move along the extending direction of the guide hole 611, thus preventing offset during movement. Specifically, multiple guide holes 611 are provided, spaced circumferentially along the second operating member 610, which further improves the stability of the second operating member 610 mounted on the leg rest plate 111 and the reliability of its movement. In this embodiment, referring to Figures 6 and 11, the leg rest 111 is provided with an operation hole 111c, and the second operating member 610 is mounted on the leg rest 111 and is at least partially exposed in the operation hole 111c. Furthermore, the second operating member 610 is also provided with an operation recess 612 (see Figure 16), which is opposite to the operation hole 111c (Figures 6 and 11). When the user needs to operate the second operating member 610, they can directly insert their finger through the operation hole 111c into the operation recess 612, and move the second operating member 610 by pushing against the side wall of the operation recess 612.

[0143] In one embodiment, the second release mechanism 600 further includes a sixth reset member 630 (Figures 13 and 14). The sixth reset member 630 may be an elastic element such as a spring or sheet, which abuts against the second operating member 610 to provide an elastic restoring force to the second operating member 610. Specifically, the sixth reset member 630 is a spring that abuts against the leg rests 110 of the second operating member 610. When the second operating member 610 is operated to move to its end position, the sixth reset member 630 is compressed. When the user releases the second operating member 610, the sixth reset member 630 returns to its original position to push the second operating member 610 back to its original position.

[0144] In one embodiment, as shown in FIG6, a retaining protrusion 118 is provided on the leg rest 111, which surrounds the operating hole 111c. This prevents children from accidentally touching the second operating member 610 while riding, causing the second operating member 610 to move to the end position. Of course, in another embodiment, as shown in FIG11, the retaining protrusion 118 can be omitted. This can improve the flatness of the surface of the leg rest 111 and prevent the retaining protrusion 118 from abutting against the legs, thus affecting the comfort of the child.

[0145] The following diagrams briefly explain the process and principle of length adjustment of the effective fixing section 330 of the safety harness 300.

[0146] Referring to Figures 12 to 14, when a user needs to increase the length of the effective fixing section 330 of the safety harness 300, their hand reaches into the operating recess 612 to push the side wall of the operating recess 612, causing the second operating member 610 to move from its original position to its endpoint position. During this process, through the transmission action of the second traction member 620, the connecting rod 550 can be pulled to drive the second driving member 540 to pivot around the second pin 530 to the fourth position. During the pivoting process, the second driving member 540 pushes the locking member 510 to pivot around the second pin 530 to the unlocked position, so that the webbing adjustment mechanism 500 is in the unlocked state. In this way, the adjusting webbing 400 is no longer pressed by the locking member 510 and can be pulled in both directions. At this time, the user can directly pull the effective fixing section 330 to increase its length. When the length of the effective fixed section 330 is adjusted to the appropriate length, the user releases the second operating member 610. The second operating member 610 automatically resets to the original position under the restoring force of the sixth reset member 630. The second driving member 540 automatically resets to the third position under the restoring force of the fifth reset member. The locking member 510 automatically resets to the locked position under the restoring force of the fourth reset member. The webbing adjustment mechanism 500 is in the locked state.

[0147] When the webbing adjustment mechanism 500 is locked, and the user needs to appropriately shorten the length of the effective fixing section 330 to secure the safety harness 300 to the child, the locking member 510 is restricted from pivoting around the second steering direction W2 due to the obstruction of the second driving member 540, but is allowed to pivot around the first steering direction W1 from the locked position. This allows the free end of the adjusting webbing 400 to be pulled in one direction. Therefore, the user can directly pull the free end to reduce the length of the first section 430, and thus the length of the effective fixing section 330, without needing to operate the second operating member 610.

[0148] Please refer to Figures 18 and 19. A second embodiment of the first aspect of the present invention also provides a safety seat 1000, which is similar to the safety seat 1000 in the first embodiment of the first aspect of the present invention. It includes a seat body 200 and a leg rest structure 100 provided by the second embodiment of the first aspect of the present invention. The leg rest structure 100 provided in the second embodiment of the first aspect of the present invention is also similar to the leg rest structure 100 in the first embodiment of the first aspect of the present invention. Therefore, the leg rest structure 100 and the safety seat 1000 of this embodiment can be considered as variations of the leg rest structure 100 and the safety seat 1000 of the first embodiment of the first aspect. Unless otherwise specified, the components and their connections in this embodiment can be referred to in the description of the first embodiment of the first aspect above. Therefore, when referring to the structure, connection relationships, etc., of the same components as in the first embodiment of the first aspect in this embodiment, the relevant illustrations can be referred to in the corresponding illustrations in the first embodiment of the first aspect. The following mainly describes the differences between this embodiment and the first embodiment of the first aspect above.

[0149] This embodiment differs from the first embodiment of the first aspect described above in the following ways.

[0150] The structure of the leg rest structure 100 is slightly different from that of the leg rest structure 100 in the first embodiment of the first aspect. Referring again to Figures 18 and 19, in this embodiment, the leg rest structure 100 is also mounted on the seat body 200 and includes a leg rest member 110, a locking mechanism 120 (see Figures 3 and 4), and a first unlocking mechanism 130. The leg rest member 110 is also slidably mounted to the seat portion 210 and can extend or retract relative to the front end of the seat portion 210, having an extended state (see Figure 19) and a retracted state (see Figure 18). The locking mechanism 120 is also provided on the leg rest member 110 and selectively engages with one of the plurality of locking portions 241 on the seat body 200 (see Figures 3 and 4). The structure and working principle of the locking mechanism 120 in this embodiment are the same as those of the locking mechanism 120 in the first embodiment of the first aspect described above, and will not be repeated here. The first unlocking mechanism 130 is also movably mounted on the leg rest 110 and operably connected to the locking member 121 of the locking mechanism 120. More specifically, the first unlocking mechanism 130 also includes a first driving member 131 (see Figures 4 and 7), a first operating member 132 (see Figures 20 and 21), and a first traction member 133 (see Figures 26 and 27). The structure and working principle of the first driving member 131 are the same as in the first embodiment described above, and will not be repeated here. Similarly, the first operating member 132 is operably mounted on the leg rest 110, and the first traction member 133 is connected between the first driving member 131 and the first operating member 132. The difference lies in the structure and working principle of the first operating member 132, which differ from the structure and working principle of the first operating member 132 in the first embodiment described above, as detailed below.

[0151] Please refer to Figures 20 and 21. In this embodiment, the first operating member 132 is pivotally connected to the leg rest member 110 and has an initial position (see Figure 20) and an end position (see Figure 21). Referring to Figures 4, 7, 20, and 21, when the first operating member 132 pivots from the initial position to the end position, the first traction member 133 is pulled. Through its transmission action, the first driving member 131 can be switched from the first position to the second position, thereby allowing the locking member 121 to be switched from the locked position to the unlocked position (see below for details).

[0152] Referring to Figures 20 to 23, in one embodiment, the second end 111b of the leg rest 111 is provided with a mounting step 115, which is generally vertical and protrudes from one side of the leg rest 111. The mounting step 115 has a receiving recess 1152, within which a first operating member 132 can be mounted using a pivot 119 (see Figure 23). When the first operating member 132 is in its initial position, it is located within the receiving recess 1152, and its surface is flush with the outer surface of the mounting step 115. Of course, in other embodiments, when the first operating member 132 is in its initial position, its surface may slightly protrude from the outer surface of the mounting step 115; this is not specifically limited here. When the first operating member 132 rotates about the pivot axis 119 relative to the mounting step 115 to the end position, the first operating member 132 flips outward about the pivot axis 119 so that the end of the first operating member 132 away from the pivot axis 119 disengages from the receiving recess 1152 and protrudes from the surface of the mounting step 115.

[0153] Please refer to Figures 22 to 24. In this embodiment, the mounting step 115 includes a mounting portion 115a and a cover plate 115b. The mounting portion 115a protrudes from the second end 111b of the leg rest 111 towards the ground. The mounting portion 115a has a cavity 115c, which communicates with the interior of the sliding member 112. The cover plate 115b is detachably connected to the mounting portion 115a to cover the cavity 115c. Specifically, the mounting portion 115a is integrally formed on the second end 111b of the leg rest 111, and the mounting portion 115a and the leg rest 111 are a single integrated structure. Optionally, in other embodiments, the mounting portion 115a may also be detachably connected to the second end 111b of the leg rest 111; no specific limitation is made here. Specifically, the mounting portion 115a is provided with a receiving groove 1153, and the cover plate 115b is provided with a notch 1154 corresponding to the receiving groove 1153. The notch 1154 and the receiving groove 1153 together form the aforementioned receiving recess 1152. Along the left-right direction of the seat body 200, at least one of the left side wall 1153b and the right side wall 1153c of the receiving groove 1153 is provided with a first pivot hole 1155. The pivot end 1323 of the first operating member 132 is provided with a second pivot hole 1324, and the pivot shaft 119 passes through the first pivot hole 1155 and the second pivot hole 1324, so that the first operating member 132 can pivot relative to the mounting step 115. When the first operating member 132 is in the initial position, it abuts against the bottom 1153a of the receiving groove 1153, and the bottom 1153a is one of the critical positions for the first operating member 132 to pivot relative to the mounting step 115.

[0154] In this embodiment, both the left side wall 1153b and the right side wall 1153c of the accommodating groove 1153 are provided with first pivot holes 1155. This improves the stability of the first operating member 132 when it is pivotally connected to the mounting step 115. It should be noted that there may be one second pivot hole 1324, which is a through hole penetrating the left and right sides of the first operating member 132; or there may be two second pivot holes 1324, which are blind holes or through holes, and the two second pivot holes 1324 are located on the left and right sides of the first operating member 132 respectively. When the second pivot hole 1324 is a through hole 1132 penetrating the left and right sides of the first operating member 132, there may be one or two pivot shafts 119. When there is one pivot shaft 119, the left and right ends of the pivot shaft 119 penetrate the first operating member 132 and are respectively inserted into the two first pivot holes 1155. When there are two pivot shafts 119, one pivot shaft 119 passes through the first pivot hole 1155 on the left and extends into the left end of the second pivot hole 1324, and the other pivot shaft 119 passes through the first pivot hole 1155 on the right and extends into the right end of the second pivot hole 1324. When there are two second pivot holes 1324, there can also be one or two pivot shafts 119. For example, when there are two pivot shafts 119, one pivot shaft 119 passes through the first pivot hole 1155 and the second pivot hole 1324 on the left, and the other pivot shaft 119 passes through the first pivot hole 1155 and the second pivot hole 1324 on the right.

[0155] Referring to Figures 3, 25, and 26, in this embodiment, the first traction member 133 includes a first traction rope 1331 and a first traction sleeve 1332 sleeved outside the first traction rope 1331. Specifically, the first traction sleeve 1332 has a first sleeve end 1332a and a second sleeve end 1332b, and the first traction rope 1331 has a first rope end 1331a adjacent to the first sleeve end 1332a and a second rope end 1331b adjacent to the second sleeve end 1332b. The first rope end 1331a is connected to the first operating member 132, and the second rope end 1331b is connected to the first driving member 131. Further, a fixing member 140 is provided at the receiving recess 1152 of the mounting step 115, which is used to fix the first sleeve end 1332a to the mounting portion 115a. The second end 1332b extends into the cavity 115c of the mounting portion 115a and the interior of the sliding member 112, connecting with the mounting base 113 (see Figure 3). When the first operating member 132 pivots outward relative to the mounting step 115, the first rope end 1331a is pulled, and the pull is transmitted through other sections of the first traction rope 1331. Simultaneously, the second rope end 1331b is pulled, thereby driving the first driving member 131 to move from the first position to the second position. Specifically, when the first operating member 132 pivots outward relative to the mounting step 115, the length of the section of the first traction rope 1331 between the first rope end 1331a and the first end 1332a increases. Since the position of the first traction sleeve 1332 is fixed, the length of the section of the first traction rope 1331 between the second rope end 1331b and the second end 1332b is correspondingly shortened, thereby causing the second rope end 1331b to pull the first driving member 131 to move from the first position to the second position. Of course, in other embodiments, the first traction sleeve 1332 may be omitted, and no specific restrictions are imposed here.

[0156] Specifically, as shown in Figures 22 and 26, the bottom 1153a of the accommodating groove 1153 has an opening 1156. The first rope end 1331a passes through the opening 1156 from the first side 1153d of the bottom 1153a to the second side 1153e of the bottom 1153a and connects with the first operating member 132. The first side 1153d and the second side 1153e of the bottom 1153a are positioned opposite each other. The first side 1153d refers to the side of the bottom 1153a away from the first operating member 132, and the second side 1153e refers to the side of the bottom 1153a facing the first operating member 132. More specifically, as shown in Figures 27 and 28, the first operating member 132 includes a first body 132a, and the first body 132a has a latch 132a1. A locking head 1333 is connected to the first rope end 1331a, and the size of the locking head 1333 is larger than the size of the locking opening 132a1. Thus, when the first rope end 1331a passes through the locking opening 132a1, the locking head 1333 can abut against the edge of the locking opening 132a1 to prevent the first rope end 1331a from detaching from the first main body 132a. Furthermore, when the first operating member 132 is installed on the mounting step 115, the locking opening 132a1 faces the ground. The first operating member 132 also includes a second main body 132b detachably connected to the first main body 132a. The second main body 132b is provided with a locking protrusion 132b1, which engages with the locking opening 132a1 to connect one end of the first traction member 133 (specifically the first rope end 1331a) to the first operating member 132. Specifically, the protrusion 132b1 is adapted to be inserted into the slot 132a1 to close the slot 132a1, thereby preventing the first rope end 1331a and the locking head 1333 from sliding towards the ground and detaching from the first body 132a. Of course, in other embodiments, the first rope end 1331a can also be directly connected to the first operating member 132 by other means (such as bonding), and the first operating member 132 can also be a single component, which is not specifically limited here.

[0157] Similarly, in this embodiment, a first unlocking mechanism 130 may be provided, comprising two first traction members 133 and two first driving members 131. The two first driving members 131 are respectively driven to engage with two locking members 121. One end of each of the two first traction members 133 (specifically, two first rope ends 1331a) is connected to a first operating member 132, and the other end of each of the two first traction members 133 (specifically, two second rope ends 1331b) is respectively connected to the two first driving members 131. When the first operating member 132 is operated, both locking members 121 can be unlocked simultaneously, thus improving the ease of unlocking. Of course, in other embodiments, one locking mechanism 120 and one first unlocking mechanism 130 may be provided; or, two locking mechanisms 120 and two first unlocking mechanisms 130 may be provided, with each first unlocking mechanism 130 driving to engage with the locking members 121 of the two locking mechanisms 120 respectively. No specific limitation is made here.

[0158] Please refer back to Figure 18. In this embodiment, the surface of the seat body 200 facing the seating space 230 is also provided with an inwardly recessed storage groove 253. This storage groove 253 is suitable for storing the Latch assembly 700 or the safety harness 300, etc. It should be noted that in this embodiment, the Latch assembly 700 is connected to the seat body 200 and is mainly used for connecting to the car seat, so that the seat body 200 can be installed on the car seat. When the Latch assembly 700 or the safety harness 300 is not needed, the Latch assembly 700 or the safety harness 300 can be folded and placed in the storage groove 253. This improves the flatness of the surface of the seat body 200.

[0159] Please refer to Figures 18, 29, and 30. In this embodiment, the seat body 200 includes armrests 260. Two armrests 260 are provided and are located on the left and right sides of the seat portion 210, respectively. When a child is seated in the seating space 230, the armrests 260 are adapted to support the child's hands and arms to improve seating comfort. In one embodiment, the safety seat 1000 also includes a storage mechanism 800, which can be located on one side of the safety seat 1000 or on both sides. Specifically, in this embodiment, storage mechanisms 800 are provided on both the left and right sides of the safety seat 1000. The storage mechanism 800 includes a movable mounting component 810 and a container 820, which can be connected by snap-fit ​​or adhesive methods, without specific limitations. In one embodiment, the storage mechanism 800 can be detachably connected to the armrest 260; of course, the storage mechanism 800 can also be fixedly connected to the armrest 260, without specific limitations.

[0160] It should be noted that the container 820 can be any suitable type of container 820, such as a cup holder or a shelf, and no specific limitation is made here. In this embodiment, the container 820 is a cup holder, which is generally cylindrical in shape, but this is only an example, and those skilled in the art can choose any other suitable shape for the container 820 according to the needs of use.

[0161] Referring to Figures 29 and 30, in this embodiment, the storage mechanism 800 and the handrail 260 are detachably connected. Specifically, the movable mounting component 810 has at least one fixing hole 811, and the handrail 260 has at least one elastic protrusion 261. The elastic protrusion 261 has a guide slope 2611, which is adapted to guide the elastic protrusion 261 into the fixing hole 811, thereby realizing the detachable connection between the movable mounting component 810 and the handrail 260. When it is necessary to separate the storage mechanism 800 from the handrail 260, press the elastic protrusion 261 to make the elastic protrusion 261 retract from the fixing hole 811, thereby separating the storage mechanism 800 from the handrail 260. After releasing the elastic protrusion 261, the elastic protrusion 261 returns to its original position to facilitate engagement with the fixing hole 811 next time. It should be noted that in this embodiment, when the fixing hole 811 is fitted onto the elastic protrusion 261, the fixing hole 811 is fitted onto the elastic protrusion 261 with an interference fit.

[0162] Referring to Figures 29 and 30, in this embodiment, the left and right armrests 260 each have a recess 262. When the storage mechanism 800 is installed on the armrest 260, a portion of the cup of the container 820 is accommodated within the recess 262. This reduces the outward protrusion of the container 820 relative to the outside of the armrest 260, reducing the possibility of interference between the storage mechanism 800 and other mechanisms within the vehicle. In this embodiment, the container 820 can be made of, for example, an elastic material (such as silicone, rubber, etc.), making it easily deformable. Specifically, a portion of the cup on the side of the container 820 away from the armrest 260 can be recessed inward to allow the container 820 to be in a folded state (not shown in the figures). When the container 820 is in the folded state, the outward protrusion of the container 820 relative to the outside of the armrest 260 is less than the outward protrusion relative to the outside of the armrest 260 when it is in use (see Figure 29). In this embodiment, the material of the movable mounting component 810 can be the same as that of the container 820; of course, the material of the movable mounting component 810 can also be different from that of the container 820, and no specific limitation is made here.

[0163] The aforementioned leg rest structure 100 and child safety seat 1000 have at least the following technical effects:

[0164] In the aforementioned leg rest structure 100, the leg rest plate 111 is mounted on the slider 112 to form the leg rest member 110. By sliding the leg rest member 110 onto the seat body 200, it can extend outward relative to the seat body 200, providing support for the child's legs and feet, making the child more comfortable. Specifically, the leg rest member 110 is slidably mounted on the seat body 200 via the slider 112. This allows the user to flexibly adjust the position of the leg rest member 110 (i.e., adjust the length of the leg rest member 110 extending relative to the seat body 200) according to the child's height, leg length, and comfort needs when the leg rest member 110 is needed, thus making the leg rest structure 100 highly adaptable. When the leg rest member 100 is not needed, the leg rest plate 111 can slide relative to the reinforcing member 240 via the slider 112 to retract relative to the seat body 200, thereby reducing the space occupied by the leg rest member 110. It should be noted that the leg rest 110, with the aid of the reinforcing member 240, can extend outward or retract inward relative to the seat body 200. The reinforcing member 240 provides a stable sliding track for the leg rest 110, which guides and supports the movement of the leg rest 110, making its movement relative to the seat body 200 more stable. Furthermore, by providing a locking mechanism 120 on the leg rest 110 and multiple locking parts 241 on the seat body 200, the user can selectively lock the locking member 121 with one of the multiple locking parts 241, thereby firmly fixing the leg rest 110 in a specific position, effectively preventing the leg rest 110 from sliding during use and ensuring the stability of the entire safety seat 1000. Users can quickly adjust the position of the leg rest 110 through simple operation, which greatly improves ease of use.

[0165] Traditional child safety seats, while featuring both webbing adjustment and leg support structures, suffer from inconvenience when adjusting the extension length or retracting the leg support. Furthermore, the webbing adjustment and leg support structures operate independently and are not linked. In contrast, the safety seat 1000 of this invention links the leg support structure 100 with the webbing adjustment mechanism 500 via a second release mechanism 600. The free end of the adjusting webbing 400 can pass through the through hole 111d and rest on the leg support plate 111, making operation more convenient for the user. This allows for easy adjustment of the webbing 400, and consequently, the safety harness 300. Moreover, regardless of whether the leg support member 110 in the leg support structure 100 is extended or retracted, the user can operate the second release mechanism 600 on the leg support structure 100 to release the webbing adjustment mechanism 500, significantly improving operational convenience. In this invention, the leg rest 111 slides relative to the reinforcing member 240 of the seat body 200 via the sliding member 112. This allows the extension length of the leg rest 111 relative to the seat body 200 to be adjustable, with various adjustment gradients. Furthermore, when the leg rest member 110 is in the retracted state, the leg rest 111 almost completely covers the seat portion 210, meaning there is a large overlap. This makes the safety seat 1000 compact in size when not in use, making storage or transportation easier.

[0166] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to and integrated with the other component, or there may be an intervening component present. The terms "mounted," "one end," "the other end," and similar expressions used in this document are for illustrative purposes only.

[0167] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0168] Referring also to Figures 31 to 33, one embodiment of the second aspect of this application provides a storage mechanism B2 for a child safety seat B1. The child safety seat B1 includes a base B16 and a seat body B15 disposed on the base B16. Optionally, the seat body B15 is movably disposed on the base B16 such that the seat body B15 can switch between an upright position (e.g., referring to Figure 37) and a reclining position (e.g., referring to Figure 39) relative to the base B16, thereby giving the child safety seat B1 at least one upright mode and / or at least one reclining mode. It is understood that the terms "upright position" and "reclining position" as used in this application should be understood according to the general concepts in the art of this application. The term "upright position" does not mean that the seat body B15 must be perpendicular to the base B16; similarly, the term "reclining position" does not mean that the seat body B15 must be parallel to the base B16. For example, when the seat body B15 is in the "upright position," the tilt angle of the seat body B15 relative to the base B16 allows the user (e.g., a child) sitting in the seat body B15 to feel that they are in a roughly upright sitting posture. Similarly, when the seat body B15 is in the "reclined position," the tilt angle of the seat body B15 relative to the base B16 allows the user sitting in the seat body B15 to feel that they are in a roughly reclining sitting posture. Therefore, the "upright position" is not the only position, but rather a series of positions that allow the user sitting in the seat body B15 to feel that they are in a roughly upright sitting posture. Accordingly, the child safety seat B1 can have a series of upright modes. Likewise, the "reclined position" is not the only position, but rather a series of positions that allow the user sitting in the seat body B15 to feel that they are in a roughly reclining sitting posture. Accordingly, the child safety seat B1 can have a series of reclining modes. It is also understandable that switching between an upright and reclining position between the seat body B15 and the base B16 refers to changing the tilt angle of the seat body B15 relative to the base B16, so that the user sitting in the seat body B15 can feel the change in their posture between an upright and reclining position. Optionally, the seat body B15 is provided with armrests B12 for the user to place their arms and hands.

[0169] For ease of description, the following reference directions are defined in this application. The left-right direction of the seat body B15 is defined with reference to the relative positions of the left and right sides of the user's body sitting in the seat body B15; the up-down direction of the seat body B15 is defined with reference to the relative positions of the user's head and buttocks sitting in the seat body B15.

[0170] Referring again to Figures 31 to 33, it should be noted that although the storage mechanism B2 is provided only on one side of the child safety seat B1 in the embodiments shown in Figures 31 to 33, this is merely exemplary. The storage mechanism B2 can also be provided on the other side of the child safety seat B1, or on both sides of the child safety seat B1. The storage mechanism B2 includes a movable mounting component B21 and a container B22. The movable mounting component B21 is pivotally connected to the body side wing B11 of the seat body B15, thereby allowing the movable mounting component B21 to pivot about a pivot axis X1 in a first direction D1. Optionally, the pivot axis X1 extends approximately along the vertical direction of the seat body B15. Optionally, the movable mounting component B21 can also be pivotally connected to the armrest B12. The container B22 can be any suitable type of container, such as a cup holder or a shelf, and this application does not limit this. It is understood that although the container B22 is generally cylindrical in the embodiments shown in Figures 31 to 33, this is merely exemplary, and those skilled in the art can choose any other suitable shape for the container B22 according to their needs. In the storage mechanism B2 provided in one embodiment of this application, the container B22 can pivot about the pivot axis X1 in the first direction D1 with the movable mounting assembly B21 to change the position of the container B22 in the left-right direction of the seat body B15, thereby realizing the adjustment of the usage position of the container B22 relative to the seat body B15.

[0171] Referring again to Figures 31 to 33, container B22 is pivotally connected to movable mounting assembly B21, thereby allowing container B22 to pivot about pivot axis X2 in a second direction D2 to change the vertical angle of container B22 relative to seat body B15, thus adjusting the usage angle of container B22 relative to seat body B15. Optionally, pivot axis X2 extends approximately along the horizontal direction of seat body B15. Optionally, pivot axis X1 is orthogonal to pivot axis X2. In this embodiment, both the first direction D1 and the second direction D2 are pivot directions. It should be noted that, in this application, the terminology indicating direction, unless explicitly stated otherwise, refers to two opposite directions. For example, a straight line direction refers to two opposite directions along that straight line, and a pivot direction refers to two opposite directions about a corresponding pivot axis. In the storage mechanism B2 provided in the embodiments shown in Figures 31 to 33, the container B22 can pivot about the pivot axis X1 in a first direction D1 with the movable mounting assembly B21, thereby adjusting the usage position of the container B22 relative to the seat body B15; the container B22 can also pivot about the pivot axis X2 in a second direction D2 relative to the movable mounting assembly B21, thereby adjusting the usage angle of the container B22 relative to the seat body B15. This will be explained in further detail below.

[0172] Referring to FIG. 32, in one embodiment of this application, the movable mounting assembly B21 includes a pivot axis B211. The pivot axis B211 is fixedly connected to the body side wing B11. Optionally, the pivot axis B211 may also be fixedly connected to the armrest B12. The pivot axis X1 is collinear with the axial direction of the pivot axis B211. A container B22 is connected to the pivot axis B21, thereby allowing the container B22 to pivot about the pivot axis X1 relative to the pivot axis B211 in a first direction D1, thereby adjusting the usage position of the container B22 relative to the seat body B15. Optionally, the pivot axis B211 is fixedly connected to the edge of the body side wing B11 or the edge of the armrest B12, thereby allowing the container B22 to move between a position located inside the body side wing B11 or the armrest B12 and a position located outside the body side wing B11 or the armrest B12. This will be described in detail below with reference to FIGS. 34 to 36.

[0173] Referring again to Figure 32, optionally, a mounting groove B13 is provided on the edge of the body side wing B11 or the edge of the armrest B12, and the pivot shaft B21 is accommodated in the mounting groove B13. By providing the mounting groove B13, movement space is provided for the mechanism (e.g., container B22) connected to the pivot shaft B21, allowing the container B22 to move between a position located inside the body side wing B11 or the armrest B12 and a position located outside the body side wing B11 or the armrest B12.

[0174] Referring again to FIG. 32, in one embodiment of this application, the movable mounting assembly B21 further includes a connector B212. The connector B212 is pivotally connected to a pivot axis B211, and a container B22 is connected to the connector B212. Therefore, the container B22 can pivot relative to the pivot axis B211 in a first direction D1 about a pivot axis X1. Optionally, a first end of the connector B212 is provided with a pivot hole B213, in which the pivot axis B211 is fitted, such that the connector B212 is pivotally connected to the pivot axis B211. The container B22 is connected to a second end of the connector B212 opposite to the first end. In the embodiment shown in Figure 32, when the first end of connector B212 pivots about the pivot axis X1 in the first direction D1, the second end of connector B212 also pivots about the pivot axis X1 in the first direction D1. Therefore, the pivot axis X2 also pivots about the pivot axis X1 in the first direction D1.

[0175] Referring again to Figure 32, in one embodiment of this application, the movable mounting assembly B21 further includes a mounting bracket B214, which is fixedly connected to the side wing B11 of the body. Optionally, the mounting bracket B214 may also be fixedly connected to the handrail B12. The mounting bracket B214 is also provided with a mounting hole B215, through which a pivot shaft B211 passes. Optionally, the mounting bracket B214 includes a main body B214a and a mounting boss B214b disposed on and protruding from the main body B214a. The mounting bracket B214 is fixedly connected to the side wing B11 of the body or the handrail B12 via the main body B214a. Optionally, the main body B214a is fixed to the side wing B11 of the body or the handrail B12 by a fastener B218. Optionally, the fastener B218 may be any suitable fixing mechanism such as a rivet, bolt, or nut. In the embodiment shown in Figure 32, two mounting bosses B214b are provided, spaced apart from each other along the extension direction of the main body B214a, thereby forming a receiving groove B214c between the two mounting bosses B214b. Optionally, only one mounting boss B214b may be provided, and the main body B214a may be configured as, for example, L-shaped. In such an embodiment, the mounting boss B214b and the L-shaped main body B214a together form the receiving groove B214c. A mounting hole B215 is provided in the mounting boss B214b, and the first end of the connector B212 is provided in the receiving groove B214c. The mounting hole B215 and the pivot hole B213 are aligned in a direction parallel to the pivot axis X1. The pivot shaft B211 passes through the mounting hole B215 and the pivot hole B213, thereby realizing a pivotable connection between the connector B212 and the mounting bracket B214.

[0176] Referring to Figures 31 and 32, in one embodiment of this application, the first ends of the mounting bracket B214 and the connector B212 are received in the mounting groove B13, and the second end of the connector B212 protrudes from the mounting groove B13. Since the mounting groove B13 is located at the edge of the body side wing B11 or the edge of the armrest B12, the second end of the connector B212 protrudes from the edge of the body side wing B11 or the edge of the armrest B12. In such an embodiment, the container B22 is connected to the second end of the connector B212 protruding from the mounting groove B13, thereby mounting the container B22 outside the mounting groove B13 to facilitate connection of the container B22 to the connector B212.

[0177] As shown in Figure 33, the mounting groove B13 may include an opening B131 and a fixing part B132 that are in communication with each other. A portion of the main body B214a of the mounting bracket B214 is accommodated in the fixing part B132 and is fixed to the fixing part B132 via a fastener B218. The mounting boss B214b and the receiving groove B214c of the mounting bracket B214 are provided in the opening B131. The opening B131 forms a notch on the edge of the side wing B11 of the main body or the edge of the armrest B12, and the second end of the connector B212 protrudes from the notch. When connector B212 pivots about axis X1 in the first direction D1, the notch provides rotational space for the pivoting of connector B212, allowing the second end of connector B212 to pivot between the inside of body wing B11 or handrail B12 and the outside of body wing B11 or handrail B12, thereby enabling container B22 to move between a position located inside body wing B11 or handrail B12 and a position located outside body wing B11 or handrail B12.

[0178] Referring again to Figure 32, in one embodiment of this application, a damping element (not shown) may be provided between the pivot hole B213 and the pivot shaft B211. For example, a damping sleeve may be provided on the inner wall of the pivot hole B213 and / or the outer wall of the pivot shaft B211 to increase the friction between the connector B212 and the pivot shaft B211. In this way, the connector B212 (and the container B22 connected to the connector B212) can be held at any pivot position during the pivot stroke of the connector B212 along the first direction D1, providing convenience for the user (e.g., a child sitting in the seat body B15). Optionally, a damping element B216 may also be provided between the connector B212 and the receiving groove B214c to increase the friction between the connector B212 and the receiving groove B214c. Optionally, as shown in Figure 32, the damping element B216 may be a damping pad. In this way, the connector B212 (and the container B22 connected to the connector B212) can be held at any pivot position during the pivot stroke of the connector B212 along the first direction D1, improving the user's ease of use.

[0179] Referring again to FIG. 32, in one embodiment of this application, container B22 is provided with a rotating connection portion B221, and a connecting rod B217 is provided at the second end of connector B212. By engaging the rotating connection portion B221 with the connecting rod B217, container B22 is connected to the second end of connector B212. In the embodiment shown in FIG. 32, the pivot axis X2 is collinear with the axial direction of connecting rod B217. Therefore, container B22 can pivot about the pivot axis X2 relative to connector B212 in the second direction D2.

[0180] Optionally, the rotating connection B221 may be provided with a hook having a generally "question mark" shape. The hook may include a pivot portion B221a and a locking portion B221b. The pivot portion B221a is configured as a generally arcuate structure, the inner diameter of which is equal to or slightly smaller than the outer diameter of the connecting rod B217, so as to allow the connecting rod B217 to be pivotally accommodated in the pivot portion B221a. The distance between the locking portion B221b and the outer wall of the container B22 is less than the outer diameter of the connecting rod B217. When the container B22 is installed, the user (e.g., a child sitting in the seat body B15, or the child's guardian) applies an external force to drive the locking portion B221b to press against the connecting rod B217, thereby forcing the rotating connection B221 to deform, such that the distance between the locking portion B221b and the outer wall of the container B22 increases to allow the connecting rod B217 to pass through the space between the locking portion B221b and the outer wall of the container B22 to enter the pivot portion B221a. Optionally, the hook is made of an elastic material. Optionally, the inner wall of the rotating connection B221 and / or the outer wall of the connecting rod B217 are provided with a damping part B222 to increase the friction between the rotating connection B221 and the connecting rod B217. In this way, the rotating connection B221 and the container B22 can be maintained at any pivot position in the pivot stroke of the rotating connection B221 along the pivot direction D2, improving the user's ease of use. In the embodiment provided with the damping part B222, when the seat body B15 switches between an upright position and a reclining position, the usage angle of the container B22 relative to the seat body B15 does not change automatically. Therefore, the user can adaptively adjust the usage angle of the container B22 relative to the seat body B15 while switching the seat body B15 between an upright position and a reclining position. In this way, the angle of use of container B22 relative to seat body B15 is always controlled, preventing container B22 from rotating on its own during the switching between upright and reclining positions of seat body B15, which could lead to accidental spillage of liquid in container B22.

[0181] The working principle of the storage mechanism B2 according to an embodiment of the second aspect of this application will be described below with reference to Figures 32, 34 to 40.

[0182] For illustrative purposes, the space between the side wings B11 or armrests B12 on both sides of the child safety seat B1 is defined as the inner side of the side wings B11 or armrests B12, and correspondingly, the side of the side wings B11 or armrests B12 away from the inner side is defined as the outer side of the side wings B11 or armrests B12. Referring also to Figures 34 to 36, which show the storage mechanism B2 in the first, second, and third use positions, respectively. It is understood that regardless of the location of the storage mechanism B2 in the first, second, or third use position, the user sitting in the seat body B15 can operate the container B22, such as placing or removing objects from the container B22, and changing the use position of the storage mechanism B2. The user can adjust the storage mechanism B2 to any of the first, second, and third use positions as needed.

[0183] In the first usage position shown in Figure 34, the container B22 is located almost entirely inside the side wing B11 or the armrest B12. The container B22 does not protrude from the side wing B11 or the armrest B12 and will not interfere with other mechanisms in the vehicle, such as the container of another child safety seat B1, thereby providing maximum installation space for installing multiple child safety seats side by side in the same row of vehicle seats.

[0184] A user (e.g., a child sitting in seat body B15, or the child's guardian) can drive container B22 and connector B212 to pivot about pivot axis X1 along the positive direction of first direction D1 from a first use position to a second use position, as shown in Figure 35. At this point, a portion of container B22 is located outside the body side wing B11 or armrest B12, and another portion is located inside the body side wing B11 or armrest B12. It is understood that the second use position is not a unique position; it can be any position between the first and third use positions. The user can flexibly adjust the storage mechanism B2 according to the needs of seating space, the need to install multiple child safety seats side-by-side, and the convenience of placing items, so that container B22 is in a suitable second use position.

[0185] The user (e.g., a child seated in seat body B15, or the child's guardian) can continue to drive container B22 and connector B212 to pivot about pivot axis X1 along the positive direction of first direction D1 from the second use position to the third use position, as shown in Figure 36. In this position, container B22 is approximately entirely located outside the body wing B11 or armrest B12. In the third use position, container B22 does not encroach on the space inside the body wing B11 or armrest B12, thus providing maximum seating space for the user. The third use position is particularly suitable for larger users. It is understood that the user can drive container B22 and connector B212, in either use position, to pivot about pivot axis D1 along the first direction D1.

[0186] Referring to Figures 37 to 40, Figures 37 and 38 show the first and second usage angles of container B22 when the child safety seat is in an upright position, respectively. Figures 39 and 40 show the third and fourth usage angles of container B22 when the child safety seat is in a reclined position, respectively. The description is based on the lower surface of base B16 as the horizontal plane. As shown in Figure 37, the child safety seat is in an upright position, and container B22 is at the first usage angle. At this time, the opening of container B22 is at an angle to the horizontal plane, posing a significant risk of liquid leakage from the cup placed inside. Therefore, the user (e.g., a child sitting in seat body B15, or the child's guardian) can pivot container B22 about the pivot axis X2 in the positive direction of the second direction D2 (i.e., the upper left direction in Figure 37) to the second usage angle, as shown in Figure 38. At this time, the opening of container B22 is substantially parallel to the horizontal plane, reducing the risk of liquid leakage from the cup placed inside. As shown in Figure 39, the child safety seat is in a reclining mode, and container B22 is in the third usage angle. At this time, the opening of container B22 is at an angle to the horizontal plane, posing a significant risk of liquid spillage from the cup placed inside. Therefore, the user can drive container B22 to pivot around the pivot axis X2 in the negative direction of the second direction D2 (i.e., the lower right direction in Figure 39) to the fourth usage angle, as shown in Figure 40. At this time, the opening of container B22 is basically parallel to the horizontal plane, reducing the risk of liquid spillage from the cup placed inside. It should be noted that the terms "first" to "fourth" used in the description of usage angles above are only to distinguish usage angles in different usage scenarios and do not imply any implication regarding the size or order of the angles. It is understood that in the storage mechanism B2 provided according to the embodiments of this application, the usage position and usage angle of container B22 can be adjusted independently.

[0187] Referring also to Figures 41 to 43, one embodiment of the second aspect of this application provides a storage mechanism B2 for a child safety seat B1. The child safety seat B1 includes a base B16 and a seat body B15 disposed on the base B16. Optionally, the seat body B15 is movably disposed on the base B16 such that the seat body B15 can switch between an upright position (e.g., referring to Figure 46) and a reclining position relative to the base B16, thereby giving the child safety seat B1 at least one upright mode and at least one reclining mode. In the embodiments shown in Figures 41 to 43, the terms "upright position," "upright mode," "reclining position," and "reclining mode" have the same meaning as in the embodiments shown in Figures 31 to 33 and will not be repeated here. Optionally, the seat body B15 is provided with armrests B12 to facilitate a user's (e.g., a child sitting in the seat body B15) placement of their arms and hands.

[0188] Referring again to Figures 41 to 43, it should be noted that although storage mechanisms B2 are provided on both sides of the child safety seat B1 in the embodiments shown in Figures 41 to 43, this is merely exemplary, and the storage mechanism B2 may also be provided only on one side of the child safety seat B1. The storage mechanism B2 includes a movable mounting component B21 and a container B22. The movable mounting component B21 is connected to the body side wing B11 and the armrest B12 located on the same side of the child safety seat B1. Optionally, the movable mounting component B21 may also be connected only to one of the body side wing B11 and the armrest B12. The movable mounting component B21 is made of an elastic material. When a user (e.g., a child sitting in the seat body B15, or the child's guardian) applies an external force to the movable mounting component B21, at least a portion of the movable mounting component B21 can deform in a first direction D1 to drive the container B22 to move in the first direction D1, thereby changing the usage position of the container B22. Optionally, the first direction D1 may be the left-right direction of the seat body B15. Container B22 can be any suitable type of container, such as a cup holder or shelf, and this application does not limit it. It is understood that although container B22 is generally cylindrical in the embodiments shown in Figures 40 to 43, this is only exemplary, and those skilled in the art can choose any other suitable shape for container B22 according to their needs.

[0189] In one embodiment of this application, container B22 is pivotally connected to movable mounting assembly B21, thereby allowing container B22 to pivot about pivot axis X2 in a second direction D2 to change the usage angle of container B22. In this embodiment, first direction D1 is a straight line direction, and second direction D2 is a pivot direction. Optionally, first direction D1 is the left-right direction of seat body B15, and pivot axis X2 extends in first direction D1. In the storage mechanism B2 provided in the embodiments shown in Figures 40 to 43, container B22 can move in first direction D1 with the deformation of movable mounting assembly B21, thereby adjusting the usage position of container B22 relative to seat body B15; container B22 can also pivot about pivot axis X2 in second direction D2 relative to movable mounting assembly B21, thereby adjusting the usage angle of container B22 relative to seat body B15. This will be described in further detail below.

[0190] Referring to Figure 42, in one embodiment of this application, the movable mounting component B21 is designed as a mounting plate B219. The mounting plate B219 is made of an elastic material. When a user (e.g., a child sitting in the seat body B15, or the child's guardian) applies an external force to the mounting plate B219, at least a portion of the mounting plate B219 deforms in a first direction, thereby driving the container B22 to move in the first direction. Optionally, the mounting plate B219 is made of an elastically deformable material such as silicone, rubber, or PE sheet. The mounting plate B219 is provided with a first mounting portion B219a, and at least one of the body side wing B11 and armrest B12 is provided with a second mounting portion B17. Through the cooperation of the first mounting portion B219a and the second mounting portion B17, the mounting plate B219 is fixed to the child safety seat B1. Optionally, the mounting plate B219 has a first mounting portion B219a at each of its opposite ends, and a second mounting portion B17 is provided on the body side wing B11 and the armrest B12 on the same side of the child safety seat B1. In this embodiment, one end of the mounting plate B219 is fixedly connected to the body side wing B11, and the other end of the mounting plate B219 is fixedly connected to the armrest B1, so as to fix the mounting plate B219 to the child safety seat B1. Optionally, one of the first mounting portion B219a and the second mounting portion B17 is a fixing hole, and the other of the first mounting portion B219a and the second mounting portion B17 is an elastic protrusion. When the fixing hole is fitted onto the elastic protrusion, the fixing hole fits the elastic protrusion with an interference fit.

[0191] Referring again to Figure 42, in one embodiment, the mounting plate B219 is further provided with a third mounting portion B219b. Optionally, the third mounting portion B219b is configured as a curved plate-like structure to form a generally U-shaped holding portion B219c together with the end of the mounting plate B219. The holding portion B219c clamps the body side wing B11 and the armrest B12 to fix the mounting plate B219 to the child safety seat B1. It should be noted that although the third mounting portion B219b is provided at both ends of the mounting plate B219 in the embodiment shown in Figure 32, this is only exemplary, and the third mounting portion B219b may only be provided at one end of the mounting plate B219; this application does not limit this.

[0192] In one embodiment, the first mounting portion B219a may be omitted, and instead, a third mounting portion B219b may be provided at at least one end of the mounting plate B219. The third mounting portion B219b is configured as a curved plate-like structure to form a generally U-shaped supporting portion B219c together with the end of the mounting plate B219. The supporting portion B219c clamps the body side wing B11 and / or the armrest B12 to secure the mounting plate B219 to the child safety seat B1.

[0193] Referring also to Figures 42 and 43, in one embodiment of this application, the mounting plate B219 is further provided with a connecting groove B219d for connecting the container B22. Correspondingly, the container B22 is provided with a mounting ring B223 for engaging with the connecting groove B219d. By inserting the mounting ring B223 into the connecting groove B219d, the container B22 is pivotally connected to the mounting plate B219. It is understood that, since the mounting ring B223 is configured to be approximately annular, and the pivot axis X2 is collinear with the axial direction of the mounting ring B223, the container B22 can pivot relative to the mounting plate B219 in a second direction D2, which is the pivoting direction around the axial direction of the mounting ring B223, i.e., around the pivot axis X2. Optionally, the connecting groove B219d includes a first groove B219e and a second groove B219f that are connected to each other, wherein the width of the first groove B219e is smaller than the width of the second groove B219f; the mounting ring B223 includes a first ring ring B223a and a second ring ring B223b that are connected to each other, wherein the diameter of the first ring ring B223a is smaller than the diameter of the second ring ring B223b, and the diameter of the second ring ring B223b is between the width of the second groove B219f and the width of the first groove B219e, and the diameter of the first ring ring B223a is smaller than the width of the first groove B219e. Therefore, when the mounting ring B223 is inserted into the connecting groove B219b, the first ring ring B223a can be inserted into the first connecting groove B219b, and the second ring ring B223b can be inserted into the second connecting groove B219b. In this way, in the direction parallel to the pivot axis X2, the connecting groove B219d restricts the mounting ring B223 from disengaging from the connecting groove B219d, while in the pivot direction around the pivot axis X2, the connecting groove B219d allows the mounting ring B223 to pivot.

[0194] The working principle of the storage mechanism B2 according to an embodiment of the second aspect of this application will be described below with reference to Figures 45 to 47.

[0195] For illustrative purposes, the space between the side wings B11 or armrests B12 on both sides of the child safety seat B1 is defined as the inner side of the side wings B11 or armrests B12. Correspondingly, the side of the side wings B11 or armrests B12 that faces away from the inner side is defined as the outer side of the side wings B11 or armrests B12. Referring to Figure 45, the container B22 and mounting plate B219, shown in dashed lines on the left side of Figure 45, are in the first use position; the container B22 and mounting plate B219, shown in solid lines in the middle of Figure 45, are in the second use position; and the container B22 and mounting plate B219, shown in dashed lines on the right side of Figure 45, are in the third use position. It is understood that regardless of whether the storage mechanism B2 is in the first, second, or third use position, the user sitting in the seat body B15 can operate the container B22, for example, by placing or removing objects from the container B22. Users can adjust the storage mechanism B2 to any of the first, second, and third usage positions as needed.

[0196] In the first usage position, at least half of the volume of container B22 is located outside the side wing B11 of the main body or the armrest B12, providing maximum seating space for the user. This first usage position is suitable for users with larger body sizes. Optionally, the first usage position is the initial position of the mounting plate B219 and container B22 in this embodiment, that is, the position of the mounting plate B219 and container B22 without applying any external force to the mounting plate B219.

[0197] A user (e.g., a child sitting in seat body B15, or the child's guardian) can apply an external force to mounting plate B219, causing it to deform in the first direction D1. This drives container B22 to move from a first use position to a second use position along the positive direction of the first direction D1 (i.e., to the right in Figure 45), as shown in Figure 45. Compared to the first use position, in the second use position, container B22 is positioned less outside the body side wing B11 or armrest B12, thus reducing the likelihood of interference with other mechanisms within the vehicle. The second use position is not a unique position; it can be any position between the first and third use positions. Users can flexibly adjust the storage mechanism B2 according to their needs for seating space, the need to install multiple child safety seats side-by-side, and the convenience of placing items, so that container B22 is in a suitable second use position.

[0198] The user (e.g., a child sitting in seat body B15, or the child's guardian) can continue to apply external force to mounting plate B219, causing it to deform in the first direction D1, thereby moving container B22 from the second use position to the third use position along the positive direction of the first direction D1, as shown in Figure 45. At this time, container B22 is approximately completely located inside the body side wing B11 or armrest B12. Container B22 does not protrude from the body side wing B11 or armrest B12 and will not interfere with other mechanisms in the vehicle, such as the container of another child safety seat B1, thus providing installation space for installing multiple child safety seats side-by-side in the same row of vehicle seats.

[0199] When the user removes the external force applied to the mounting plate B219 and there is sufficient space outside the main body side wing B11 or the armrest B12, under the action of the elastic restoring force of the mounting plate B219 itself, the mounting plate B219 drives the container B22 to move from the third use position, through the second use position, to the first use position along the negative direction of the first direction D1 (i.e., the leftward direction in Figure 45).

[0200] Referring also to Figures 46 and 47, which show the first and second usage angles of container B22 when the child safety seat is in an upright position, respectively. The explanation is based on the lower surface of base B16 as the horizontal plane. As shown in Figure 46, the child safety seat is in the upright position, and container B22 is at the first usage angle. At this time, the opening of container B22 is at an angle to the horizontal plane, posing a significant risk of liquid leakage from the cup placed inside. Therefore, the user (e.g., a child sitting in seat body B15, or the child's guardian) can pivot container B22 about the pivot axis X2 in the positive direction of the second direction D2 (i.e., the upper left direction in Figure 46) to the second usage angle, as shown in Figure 47. At this time, the opening of container B22 is substantially parallel to the horizontal plane, reducing the risk of liquid leakage from the cup placed inside. It is understandable that, although the above description of the adjustment of the usage angle of container B22 is based on the child safety seat B1 being in upright mode, these descriptions of the adjustment of the usage angle of container B22 also apply to the child safety seat B1 being in reclined mode. It should be noted that the terms "first" and "second" used in the above description of usage position and angle are only to distinguish usage angles in different usage scenarios and do not imply any implication regarding the size or order of the angles. It is understood that, in the storage mechanism B2 provided according to the embodiments of this application, the usage position and usage angle of container B22 can be adjusted independently.

[0201] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0202] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
