Description

Technical Field

[0001] This invention relates to the field of infant and toddler products technology, and in particular to a car seat. Background Technology

[0002] Some car seats offer Harness and Booster modes. In Harness mode, the vehicle's seatbelt secures the car seat, while the seat's harnesses (including lap belts, shoulder straps, and crotch straps) restrain the child. When the car seat is in forward-facing mode, it typically has a forward clamp for securing the seatbelt. When the car seat is in rear-facing mode, it typically has a rear clamp for securing the seatbelt. When the car seat can switch between forward-facing and rear-facing modes, it typically has both forward and rear clamps for securing the seatbelt.

[0003] In Booster mode, the vehicle's seatbelt is used to restrain children sitting in car seats. Since the harness is not needed in Booster mode, the harness portion (such as the lap belt) needs to be removed before it can be stored. As a result, the design layout of the rear-facing clamp is affected by the harness removal structure, making the existing clamp structure complex and space-consuming. Summary of the Invention

[0004] Therefore, it is necessary to provide a clamp structure and a safety seat that are simple in design and occupy little space to address the above problems.

[0005] According to a first aspect of the present invention, a safety seat is provided, comprising a housing and a clamping structure, the clamping structure including a rotating rod and a clamping rod. The rotating rod is rotatably connected to the housing. The clamping rod is fixedly connected to the rotating rod and is rotatable relative to the housing between a first position and a second position. The clamping rod has a clamping portion. When a strap is inserted into the clamping portion and the clamping rod rotates from the second position to the first position, the clamping rod tensions the strap through the clamping portion.

[0006] In some embodiments, the shape of the clamping portion is configured such that when the belt is passed through the clamping portion and the clamping rod rotates from the second position to the first position, a portion of the belt passing through the clamping portion wraps around the clamping portion, thereby tensioning the belt.

[0007] In some embodiments, the clamp structure includes a locking element that can be detachably locked to the housing when the clamp rod is in the first position.

[0095] Figure 1 and Figure 2 A perspective view of a safety seat 1000 according to a first embodiment of the present invention is shown. The safety seat 1000 includes a seat body 2000 and a base (not shown in the first embodiment, but can be seen in the second embodiment). Figure 12 (The base 5000 is shown). The seat body 2000 and the base 500 may each have a housing. The safety seat 1000 also includes a clamp structure 100. The clamp structure 100 can be mounted on the housing of the seat body 2000 (hereinafter referred to as the seat body housing) 200, or on the housing of the base (hereinafter referred to as the base housing). The following description of the safety seat 1000 takes the clamp structure 100 mounted on the seat body housing 200 as an example.

[0096] Please see Figure 1 and Figure 2 In one embodiment, the seat body housing 200 includes a seat portion 210, a backrest portion 220, and a headrest portion 230. The seat portion 210 and the backrest portion 220 are connected and arranged at an angle. The headrest portion 230 is connected to the upper end of the backrest portion 220. The seat portion 210 is mainly used to support the child's buttocks and legs, the backrest portion 220 is mainly used to support the child's back, and the headrest portion 230 is mainly used to support the child's head. The seat portion 210 and the backrest portion 220 may be integrally formed; alternatively, they may be separate components assembled together. The seat portion 210 includes a seat portion 211 and seat side portions 212 extending upward on opposite sides (first side and second side) of the seat portion 211. The backrest portion 220 includes a backrest 221 and backrest side portions 222 extending forward on opposite sides (first side and second side) of the backrest 221. The seat side portion 212 of the seat portion 210 and the backrest side portion 222 of the backrest portion 220 form the side portion of the seat body shell 200.

[0097] In one embodiment, the child safety seat 1000 includes a forward clamp structure 1001 and a rearward clamp structure 1002. The forward clamp structure 1001 and the rearward clamp structure 1002 are respectively used to secure the child safety seat 1000 to the vehicle seat via a strap 900, such as the strap of a vehicle seat belt, when the child safety seat 1000 is in a forward-facing use mode and a rearward-facing use mode (see [link]). Figure 2 and Figure 6 (For clarity, the strap is omitted in the other figures). Specifically, the forward clamp structure 1001 is disposed on the backrest 221, and each of the two backrest sides 222 has a forward through hole 2221, which are arranged opposite to each other. When the child safety seat 1000 is installed on the vehicle seat in forward-facing mode, the strap 900 can pass through one forward through hole 2221, the forward clamp structure 1001, and the other forward through hole 2221 in sequence and connect to a fastener on the vehicle seat, such as a seat belt buckle, thereby securing the child safety seat 1000 to the vehicle seat. The rearward clamp structure 1002 is disposed on the seat 211, and each of the two seat sides 212 has a rearward through hole 2121, which are arranged opposite to each other. When the child safety seat 1000 is installed on the vehicle seat in rear-facing mode, the belt body 900 (e.g., the belt body of a vehicle seat belt) can pass through a rear-facing through hole 2121, a rear-facing clamp structure 1002 and another rear-facing through hole 2121 in sequence and connect to a fastener on the vehicle seat (e.g., a vehicle seat belt buckle), thereby securing the child safety seat 1000 to the vehicle seat.

[0098] In one embodiment, the rear clamp structure 1002 adopts the clamp structure 100 provided according to an embodiment of the present invention.

[0099] Please refer to the following: Figure 3 and Figure 6The clamp structure 100 includes a rotating rod 110, a clamp rod 120, and a locking member 130. The rotating rod 110 is rotatably connected to the seat 211 relative to the seat 211. The clamp rod 120 is fixedly connected to the rotating rod 110 and can rotate with the rotating rod 110 relative to the seat 211 between a first position and a second position. The clamp rod 120 has a clamping portion 128 through which the belt 900 passes. The locking member 130 is provided at the end of the clamp rod 120 away from the rotating rod 110. When the clamp rod 120 is in the first position, the locking member 130 can be detachably engaged with the seat 211, thereby locking or unlocking the rotation of the clamp rod 120 relative to the seat 211. When the clamp rod 120 is in the second position, the belt 900 can be passed through or removed from the clamping portion 128. When the belt 900 is inserted into the clamping part 128 and the clamping rod 120 rotates from the second position to the first position, the clamping rod 120 tensions and compresses the belt 900 through the clamping part 128. Specifically, when the belt 900 sequentially passes through a rear through hole 2121, the clamping part 128 of the clamping rod 120, and another rear through hole 2121 and is connected to the fastener on the vehicle seat, the user can rotate the clamping rod 120 from the second position to the first position. During this process, the rotation of the clamping part 128 causes a portion of the belt 900 inserted therein to wrap around the clamping part 128, thereby tensioning the entire belt 900. When the clamping rod 120 reaches the first position, the clamping rod 120 presses the tensioned belt 900 onto the seat part 211, at which point the belt 900 can be used to securely fasten the safety seat 1000.

[0100] Specifically, the seat portion 211 is provided with a rotating rod receiving groove 201 and a rotating rod mounting hole portion 202 communicating with the rotating rod receiving groove 201. The rotating rod 110 is received in the rotating rod receiving groove 201 and rotatably inserted into the rotating rod mounting hole portion 202. The rotating rod mounting hole portion 202 can prevent the rotating rod 110 from disengaging from the top of the rotating rod receiving groove 201, for example, from disengaging from the top of the rotating rod receiving groove 201 in a direction perpendicular to the seat surface 2110 of the seat portion 211. It should be understood that the number of rotating rod mounting holes 202 can be one or more. In the illustrated embodiment, the seat portion 211 is provided with two rotating rod mounting holes 202.

[0101] The clamping rod 120 includes a first rod portion 121, a second rod portion 122, and a third rod portion 123 connected in sequence. The first rod portion 121 and the second rod portion 122 form a clamping portion 128 through which the belt 900 passes. In the illustrated embodiment, the clamping portion 128 is U-shaped, and the belt 900 can enter or exit the clamping portion 128 from the open end of the clamping portion 128. Because the clamping portion 128 is U-shaped, when the clamping rod 120 turns from the second position to the first position, a portion of the belt 900 passing through the clamping portion 128 forms additional windings on the first rod portion 121 and the second rod portion 122, thereby tensioning the entire belt 900. It should be understood that the clamping portion 128 can also have other shapes, such as V-shaped, an open ring, elliptical, etc., without limitation, as long as it can achieve tensioning and compression of the belt 900. The extending directions of the first rod portion 121 and the second rod portion 122 are parallel to the extending direction of the rotating rod 110. The second rod portion 122 is fixedly connected to the rotating rod 110, for example, by welding, bonding, or through an intermediate connector (not shown). It should be understood that the second rod portion 122 may also be integrally formed with the rotating rod 110. The third rod portion 123 extends from the second rod portion 122 away from the rotating rod 110 at the open end of the clamping portion 128. More specifically, the extension direction of the third rod portion 123 is transverse to (e.g., perpendicular to) the plane containing the clamping portion 128. A locking member 130 is provided at the end of the third rod portion 123 away from the rotating rod 110. The seat portion 211 is also provided with a clamping portion receiving groove 203 communicating with the rotating rod receiving groove 201, a third rod portion receiving groove 204 communicating with the clamping portion receiving groove 203, and a locking member receiving groove 205 communicating with the third rod portion receiving groove 204. When the clamping rod 120 is in the first position, the clamping part 128, the third rod part 123, and the engaging member 130 are respectively located in the clamping part receiving groove 203, the third rod part receiving groove 204, and the engaging member receiving groove 205, and the clamping part 128 is hidden in the seat part 211, that is, the clamping part 128 is not visible from above the seat part 211. For example, when the clamping rod 120 is in the first position, the clamping part 128 is arranged perpendicular to the seat surface 2110 of the seat part 211 and is located below the second rod part 122, so that when viewed from above the seat part 211, the clamping part 128 is obscured by the second rod part 122. When the clamping rod 120 is in the first position, since the rotating rod 110, the clamping rod 120, and the engaging member 130 are all located in the groove of the seat part 211, the seat part 211 can remain substantially flat without affecting the child's riding. When the engaging member 130 disengages from the seat 211, the clamping rod 120 can be rotated upwards, thereby rotating the clamping rod 120 from a first position to a second position. The rotation of the clamping rod 120 from the first position to the second position is a rotation about the central axis of the rotating rod 110.When the clamping lever 120 is in the second position, the clamping part 128, the third lever part 123, and the engaging member 130 disengage from the clamping part receiving groove 203, the third lever part receiving groove 204, and the engaging member receiving groove 250, so that the clamping part 128 is exposed in the seat part 211. At this time, the belt body 900 can be easily passed through or removed from the clamping part 128.

[0102] See Figure 6 , Figure 8A and 8B , Figure 9A and 9B as well as Figure 10 In one embodiment, the engaging member 130 includes an engaging body 131 and a locking portion 132 protruding from the engaging body 131. The engaging body 131 has an inner cavity, and the end of the third rod portion 123 away from the rotating rod 110 is inserted into the inner cavity of the engaging body 131. A limiting hole 1312 is provided on the side wall defining the inner cavity of the engaging body 131. A limiting pin 133 is fixedly connected to the third rod portion 123 through the limiting hole 1312, for example, by threading it to a fastening hole 1231 of the third rod portion 123. The extending direction of the limiting hole 1312 is perpendicular to the extending direction of the third rod portion 123. When the clamping rod 120 is in the first position, the engaging body 131 can be in a locked position relative to the limiting pin 133 and the third rod portion 123 along the extending direction of the limiting hole 1312 (see...). Figure 3 ) and unlock location (see Figure 4 The movement between the locking holes 1312 and 1312 is limited. The two ends of the limiting hole 1312 can engage with the limiting pin 133 to limit the travel of the locking body 131. A locking component 213 (see [reference]) can be provided on the seat 211. Figure 10When the clamp lever 120 is in the first position, and the engaging body 131 is in the locked position, the locking part 132 engages with the matching part 213, thereby locking the rotation of the clamp lever 120. When the engaging body 131 is in the unlocked position, the locking part 132 disengages from the matching part 213, thereby unlocking the rotation of the clamp lever 120. In the illustrated embodiment, the matching part 213 is the inner edge of a crotch strap buckle storage groove (which also serves as an engaging part storage groove 205) provided on the seat 211. The locking part 132 protrudes from the engaging body 131 in a direction perpendicular to the extending direction of the third lever 123. When the clamp lever 120 is in the first position, the locking part 132 is located on the side of the engaging body 131 facing the seat 211. Furthermore, the locking part 132 is hook-shaped, and the hook-shaped locking part 132 can form a snap-fit ​​engagement with the inner edge of the crotch strap buckle storage groove 205 (i.e., the clip 213). Furthermore, the hook-shaped locking part 132 is provided with a locking protrusion 1321 on the side facing the engaging body 131, and a locking recess 2131 is provided at the corresponding position of the inner edge of the crotch strap buckle storage groove 205. When the locking part 132 and the clip 213 are engaged together, the locking protrusion 1321 can be engaged in the locking recess 2131, so that the locking of the rotation of the clamp rod 120 is more secure.

[0103] Furthermore, the engaging member 130 also includes an engaging body reset member 134, which provides an elastic force to bias the engaging body 131 toward the locked position. In the illustrated embodiment, the engaging body reset member 134 is an elastic rib that abuts against the end wall of the limiting hole 1312 and the limiting pin 133, and biases the engaging body 131 away from the limiting pin 133 along the extending direction of the limiting hole 1312. In some embodiments, the elastic rib may be integrally connected to the engaging body 131. In some embodiments, a spring may also be used instead of the elastic rib.

[0104] Furthermore, the engaging member 130 also includes an operating block 135. The operating block 135 is fixedly connected to the end of the third lever portion 123 away from the rotating lever 110, and movably connected to the engaging body 131, allowing the user to easily unlock the engaging member 130 and the seat portion 211 by holding the operating block 135 and pressing the engaging body 131 with their fingers. In the illustrated embodiment, the operating block 135 has a U-shaped receiving cavity 1351 (see...). Figure 10The engaging body 131 is movably accommodated in the receiving cavity 1351 of the operating block 135 and extends from the open end of the receiving cavity 1351. A limiting pin 134 passes sequentially through the side wall of the limiting cavity 1351, the limiting hole 1312, and the fastening hole 1231 of the operating block 135, thereby fixing the operating block 135 to the end of the third rod portion 123. In the illustrated embodiment, the end of the third rod portion 123 away from the rotating rod 110, the receiving cavity 1351 of the operating block 135, and the inner cavity of the engaging body 131 all have a generally rectangular cross-section, thus restricting the rotation of the engaging body 131 relative to the operating block 135 and the rotation of the end of the third rod portion 123 relative to the engaging body 131. It should be understood that the cross-sections of the end of the third rod portion 123 away from the rotating rod 110, the receiving cavity of the operating block 135, and the inner cavity of the engaging body 131 can also be other shapes that have the effect of restricting rotation.

[0105] See Figure 6 and Figure 7 In one embodiment, the rotating rod 110 can be used as a second waist belt fastener 310. A second waist belt (e.g., a second-side waist belt, such as a left waist belt) can be fitted onto the rotating rod 110, which can limit and fix the second waist belt fitted onto it. When the clamp rod 120 is in the second position, the rotating rod 110 is movably accommodated in the rotating rod receiving groove 201 between the third and fourth positions along the direction parallel to the seat surface 2110 of the seat portion 211. When the rotating rod 110 is in the third position, the first end of the rotating rod 110 is rotatably inserted into the rotating rod mounting hole portion 202. When the rotating rod 110 is in the fourth position, the first end of the rotating rod 110 exits the rotating rod mounting hole portion 202 and forms a gap with the rotating rod mounting hole portion 202. The second waist belt can be fitted onto or removed from the first end of the rotating rod 110 through this gap.

[0106] In one embodiment, when the rotating rod 110 is in the third position, the second end of the rotating rod 110 is abutted by an elastic limiting finger 216 provided on the seat 211. The bottom wall of the rotating rod mounting hole 202 for inserting the second end of the rotating rod 110 and the elastic limiting finger 216 together restrict the movement of the rotating rod 110 in a direction parallel to the seat surface 2110 of the seat 211. When it is necessary to install or remove the second belt, the user can press down on the elastic limiting finger 216, causing the elastic limiting finger 216 to disengage from the second end of the rotating rod 110, thereby allowing the rotating rod 110 to move from the third position to the fourth position. When the second belt has been installed or removed, the user can move the rotating rod 110 from the fourth position to the third position. At this time, the elastic limiting finger 216 can return to its original shape and abut against the second end of the rotating rod 110. Furthermore, the limiting clamping block 215 is fixedly connected to the seat portion 211 above the rotating rod receiving groove 201 to further restrict the rotating rod 110 from disengaging from the top of the rotating rod receiving groove 201. Furthermore, when the rotating rod 110 moves from the third position to the fourth position, the clamping portion 128 of the clamping rod 120 can abut against the limiting clamping block 215, thereby preventing the rotating rod 110 from disengaging from the front end of the rotating rod receiving groove 201.

[0107] See Figure 5In one embodiment, the safety seat 1000 further includes a first lap belt fastener 320 for securing a first lap belt (e.g., a lap belt on a first side, such as a right lap belt). The first lap belt fastener 320 may include a lap belt fastening rod 321 and an operating lever 322 fixedly connected to a second end of the lap belt fastening rod 321. The extending direction of the operating lever 322 may be transverse to (e.g., perpendicular to) the extending direction of the lap belt fastening rod 321. In the illustrated embodiment, the lap belt fastening rod 321 and the operating lever 322 are integrally connected, and the lap belt fastening rod 321 and the operating lever 322 together form an L-shaped structure. It should be understood that in other embodiments, the lap belt fastening rod 321 and the operating lever 322 may also be two separate components fixedly connected together. The seat portion 211 may be provided with a lap belt fastening rod receiving groove 206 and a lap belt fastening rod mounting hole portion 207 and an operating lever receiving groove 208 communicating with the lap belt fastening rod receiving groove 206. The belt fixing rod 310 is received in the belt fixing rod receiving groove 206 and rotatably inserted into the belt fixing rod mounting hole 207 relative to the seat 211. The belt fixing rod mounting hole 207 prevents the belt fixing rod 310 from dislodging from the belt fixing rod receiving groove 206 above it. It should be understood that there can be one or more belt fixing rod mounting holes 207; in the illustrated embodiment, the seat 211 has two belt fixing rod mounting holes 207. The operating lever 322 can rotate between a fifth position and a sixth position relative to the seat 211 via the belt fixing rod 321. When the operating lever 322 is in the fifth position, it is received in the operating lever receiving groove 208 and engaged in the buckle 323 provided on the seat 211. When the operating lever 322 is rotated upwards, it disengages from the operating lever receiving groove 208 and the buckle 330 and rotates from the fifth position to the sixth position. The belt fixing rod 310 is movably accommodated in the belt fixing rod receiving groove 206 between the seventh and eighth positions along the direction parallel to the seat surface 2110 of the seat portion 211. When the belt fixing rod 310 is in the seventh position, the first end of the belt fixing rod 310 is inserted into the belt fixing rod mounting hole portion 207. When the operating lever 322 is in the sixth position, the operating lever 322 can be pulled to move the belt fixing rod 310 from the seventh position to the eighth position. At this time, the first end of the belt fixing rod 310 is disengaged from the belt fixing rod mounting hole portion 207 and forms a gap with the belt fixing rod mounting hole portion 207. The first belt can be fitted onto one end of the belt fixing rod 310 through this gap, or removed through this gap. When installing or removing the first belt, the operating lever 322 can be pulled again to move the belt fixing rod 310 from the eighth position to the seventh position, and the operating lever 322 can be rotated from the sixth position to the fifth position, thereby fixing the first belt or removing the first belt.The seat 211 is also provided with a relief groove 2010 located at the end of the operating lever receiving groove 208 and communicating with the operating lever receiving groove 208. The size of the relief groove 2010 is usually larger than the diameter of the operating lever 322. The function of the relief groove 2010 is to facilitate the user to bend the end of the operating lever 322 by hand.

[0108] It should be understood that in other embodiments, the operating lever 322, the operating lever receiving groove 208, and the buckle 330 may be omitted, and a component similar to the elastic limiting finger 216 may be used to unlock and lock the movement of the belt fixing lever 310 between the seventh and eighth positions. It should be understood that in this case, the first end of the belt fixing lever 310 can be non-rotatably inserted into the belt fixing lever mounting hole 207 relative to the seat 211.

[0109] It should be understood that other types of first and second belt fasteners can also be used in this invention. Because the clamp structure 100 of this application has a simple structure and small size, its arrangement will not affect the arrangement of other types of first and second belt fasteners. Furthermore, when the rotating rod 110 of the rear clamp structure 100 is used simultaneously as a first or second belt fastener, the space occupied by the rear clamp structure and the first and second belt fasteners can be further saved.

[0110] Figure 11 and Figure 12 A perspective view and a side view of a safety seat 1000' provided according to a second embodiment of the present invention are shown respectively. The safety seat 1000' includes a seat body 2000', a base 5000, and clamp structures 100' and 100'' provided according to an embodiment of the present invention. The seat body 2000' has a seat body housing 200'. The base 5000 has a base housing 500. The clamp structures 100' or 100'' can be mounted on the seat body housing 200' or on the base housing 500. The safety seat 1000' will be described below with the clamp structures 100' and 100'' mounted on the seat body housing 200' as an example.

[0111] Please see Figure 11 and Figure 12In one embodiment, the seat body housing 200' includes a seat portion 210', a backrest portion 220', and a headrest portion 230'. The seat portion 210' includes a seat portion 211' and seat side portions 212' extending upwards on opposite sides of the seat portion 211'. The backrest portion 220' includes a backrest 221' and backrest side portions 222' extending forward on opposite sides of the backrest 221'. The seat side portions 212' of the seat portion 210' and the backrest side portions 222' of the backrest portion 220' form the sides of the seat body housing 200'. The arrangement, connection relationship, and function of the seat portion 210', backrest portion 220', and headrest portion 230' can be referred to the connection relationship and function of the seat portion 210, backrest portion 220, and headrest portion 230 in the first embodiment of the present invention, and will not be repeated here.

[0112] In one embodiment, the safety seat 1000' includes a forward clamp structure 1001' and a rearward clamp structure 1002'. The forward clamp structure 1001' is disposed on the backrest 221', and each of the two backrest sides 222' has a forward through hole 2221'. The rearward clamp structure 1002' is disposed on the seat 211', and each of the two seat sides 212' has a rearward through hole 2121'. The arrangement, cooperation relationship, and function of the forward clamp structure 1001', the rearward clamp structure 1002', the forward through hole 2221', and the rear through hole 2121' can be referred to the arrangement, cooperation relationship, and function of the forward clamp structure 1001, the rearward clamp structure 1002', the forward through hole 2221, and the rear through hole 2121 in the first embodiment of the present invention, and will not be repeated here.

[0113] In one embodiment, the forward clamp structure 1001' adopts the clamp structure 100' provided according to an embodiment of the present invention, and the rear clamp structure 1002' adopts the clamp structure 100'' provided according to an embodiment of the present invention. The clamp structures 100' and 100'' are substantially the same in structure. It should be understood that the clamp structures 100' and 100'' may have the same or different dimensions.

[0114] Specifically, see Figure 16 and Figure 17The clamp structure 100' or 100'' includes a rotating rod 110' or 110'', a clamp rod 120' or 120'', and a locking member 130' or 130''. The clamp rod 120' or 120'' includes a first rod portion 121' or 121'', a second rod portion 122' or 122'', a third rod portion 123' or 123'', and a clamping portion 128' or 128''. The connection and cooperation relationship between the rotating rod 110' or 110'', the first rod portion 121' or 121'', the second rod portion 122' or 122'', the third rod portion 123' or 123'', and the clamping portion 128' or 128'' can be referred to the connection and cooperation relationship between the rotating rod 110, the first rod portion 121, the second rod portion 122, and the third rod portion 123 in the first embodiment of the present invention, and will not be repeated here.

[0115] The connection and mating relationship between the clamp structure 100' (i.e., the rear clamp structure 1002') and the seat 211' will be described in detail below.

[0116] See Figures 13 to 15 The rotating rod 110' is rotatably connected to the seat 211'. The clamp rod 120' can rotate with the rotating rod 110' relative to the seat 211' between a first position and a second position. A locking member 130' is provided at the end of the clamp rod 120'. When the clamp rod 120' is in the first position, the locking member 130' can be detachably locked onto the seat 211', thereby locking or unlocking the rotation of the clamp rod 120' relative to the seat 211'. When the clamp rod 120' is in the second position, the belt can be passed through or removed from the clamping part 128'. When the belt is passed through the clamping part 128' and the clamp rod 120' rotates from the second position to the first position, the clamp rod 120' tensions and compresses the belt through the clamping part 128'.

[0117] The seat 211' is provided with a rotating rod receiving groove 201' and a rotating rod mounting hole 202' communicating with the rotating rod receiving groove 201'. The rotating rod 110' is received in the rotating rod receiving groove 201', and the first end of the rotating rod 110' is rotatably inserted into the rotating rod mounting hole 202'. A limiting clamping block 215' is fixedly connected to the seat 211' from above the rotating rod receiving groove 201' at the second end of the rotating rod 110' to prevent the rotating rod 110' from disengaging from above the rotating rod receiving groove 201'. The rotating rod 110' can rotate relative to the limiting clamping block 215'. For example, the limiting clamping block 215' has an additional rotating rod receiving groove 2151' on the side facing the rotating rod receiving groove 201' (see...). Figure 18When the additional rotating rod receiving groove 2151' and the rotating rod receiving groove 201' together define the rotating rod receiving cavity that allows the rotating rod 110' to rotate, the limiting clamping block 215' is also provided with a locking hole 2152', and the seat 211' is provided with a fixing hole 1251' (see...). Figure 19 Fasteners can pass through locking hole 2152' and fixing hole 1251' to fix the limiting clamping block 215' onto the seat 211'.

[0118] The seat 211' is also provided with a clamping part receiving groove 203' communicating with the rotating rod receiving groove 201', a third rod receiving groove 204' communicating with the clamping part receiving groove 203', and a locking member receiving groove 205' communicating with the third rod receiving groove 204'. In the illustrated embodiment, the rotating rod receiving groove 201' and the clamping part receiving groove 203' are combined into one receiving groove. When the clamping rod 120' is in the first position, the clamping part 128', the third rod part 123', and the locking member 130' are respectively located in the clamping part receiving groove 203', the third rod receiving groove 204', and the locking member receiving groove 205', and the clamping part 128' is hidden in the seat 211', that is, the clamping part 128' cannot be seen from above the seat 211'. For example, when the clamping lever 120' is in the first position, the clamping part 128' is positioned perpendicular to the seat surface 2110' of the seat portion 211' and below the second lever part 122', so that when viewed from above the seat portion 211', the clamping part 128' is obscured by the second lever part 122'. When the clamping lever 120' is in the first position, since the rotating lever 110', the clamping lever 120', and the engaging member 130' are all located in the groove of the seat portion 211', the seat portion 211' can remain substantially flat without affecting the child's seating. When the engaging member 130' disengages from the seat portion 211', the clamping lever 120' can be rotated upwards, thereby rotating the clamping lever 120' from the first position to the second position. When the clamping lever 120' is in the second position, the clamping part 128', the third lever part 123', and the engaging member 130' disengage from the clamping part receiving groove 203', the third lever part receiving groove 204', and the engaging member 130', so that the clamping part 128' is exposed in the seat part 211'. At this time, the belt can be easily inserted into or removed from the clamping part 128'.

[0119] See Figure 16 and Figure 17In one embodiment, the engaging member 130' includes an engaging body 131' and a locking portion 132' protruding from the engaging body 131'. The engaging body 131' has an inner cavity, and the end of the third rod portion 123' remote from the rotating rod 110' is inserted into the inner cavity of the engaging body 131'. A limiting hole 1312' is provided on the side wall defining the inner cavity of the engaging body 131'. A limiting pin 133' is fixedly connected to the third rod portion 123' through the limiting hole 1312', for example, by threading it to the fastening hole 1231' of the third rod portion 123'. The engaging body 131' is movable between a locked position and an unlocked position relative to the limiting pin 133' and the third rod portion 123' along the extending direction of the limiting hole 1312'. The two ends of the limiting hole 1312' can cooperate with the limiting pin 133' to limit the travel of the engaging body 131'. See again Figures 13 to 15 A locking member 213' may be provided on the seat 211'. When the clamp rod 120' is in the first position, when the engaging body 131' is in the locked position, the locking part 132' engages with the locking member 213', thereby locking the rotation of the clamp rod 120'. When the engaging body 131' is in the unlocked position, the locking part 132' disengages from the locking member 213', thereby unlocking the rotation of the clamp rod 120'.

[0120] Unlike the first embodiment, in the second embodiment, the extending direction of the limiting hole 1312' is parallel to the extending direction of the third rod portion 123'. The locking portion 132' protrudes from the end of the engaging body 131' away from the third rod portion 123'. The engaging member 213' is disposed at one end of the engaging member receiving groove 205 away from the third rod portion receiving groove 204, and together with the bottom wall of the engaging member receiving groove 205, defines the locking portion receiving groove 2012' (see...). Figure 15 When the engaging member 130' is in the locked position, the locking part 132' extends into the locking part receiving groove 2012', thereby engaging with the matching member 213'. When the engaging member 130' moves from the locked position to the unlocked position, the locking part 132' exits the locking part receiving groove 2012', thereby disengaging from the matching member 213'. Furthermore, the locking part 132' is provided with a locking protrusion 1321', and the matching member 213' is provided with a locking recess 2131'. When the locking part 132' extends into the locking part receiving groove 2012', the locking protrusion 1321' and the locking recess 2131' engage together, making the engagement between the locking part 132' and the matching member 213' more secure. It should be understood that in other embodiments, a locking recess may be provided on the locking part 132', and a locking protrusion may be provided on the matching member 213'.

[0121] Furthermore, the engaging component 130' also includes an engaging body reset component 134', which provides an elastic force to bias the engaging body 131' toward the locked position. In the illustrated embodiment, the engaging body reset component 134' is a spring that abuts against the end wall of the limiting hole 1312' and the limiting pin 133', and biases the engaging body 131' away from the limiting pin 133' (i.e., toward the locked position) along the extending direction of the limiting hole 1312'. It should be understood that in some embodiments, a spring can be used instead of an elastic rib in a manner similar to the first embodiment. Furthermore, the engaging body 131' may also be provided with a relief groove 1313' to facilitate the user to move the engaging body 131'.

[0122] See Figure 11 and Figure 13-15 In one embodiment, the seat body housing 200' further includes a reinforcing tube 240' (see...). Figure 14 , Figure 13 and Figure 15 (The reinforcing tube is omitted in the original text). The reinforcing tube 240' extends from the backrest 221' to the seat portion 211' to enhance the strength of the seat body shell 200', thereby improving its service life. The reinforcing tube 240' is arranged on one side of the seat portion 211'. More specifically, the seat body shell 200' includes a reinforcing tube receiving groove 209' disposed between the backrest 221' and the seat portion 211' and the side portion of the seat body shell 200'. The reinforcing tube 240' is received in the reinforcing tube receiving groove 209'. The locking piece 213' may be a locking tab disposed between the reinforcing tube 240' and the side wall of the reinforcing tube receiving groove 209', and the locking piece 213' may be fixed to the reinforcing tube 240'.

[0123] See Figure 13-15 In one embodiment, the safety seat 1000' further includes a first lap belt fastener 320' and a second lap belt fastener 310' respectively disposed between the sidewalls of the reinforcing tube 240' and the reinforcing tube receiving groove 209' on the first and second sides. The first lap belt fastener 320' and the second lap belt fastener 310' may each be a sheet having a slot allowing the lap belt to pass through. The first lap belt fastener 320' and the second lap belt fastener 310' may be fixedly connected to the reinforcing tube 240' on the first and second sides, respectively. The first lap belt fastener 320' may be disposed adjacent to the clip 213'. The clamp structure 100', the first lap belt fastener 320', and the second lap belt fastener 310' of this application all have simple structures and occupy less space.

[0124] The following will describe the connection and mating relationship between clamp structure 100'' (i.e., forward clamp structure 1001') and backrest 221'. Clamp structure 100'' is basically the same as clamp structure 100', and the connection relationship between clamp structure 100'' and backrest 221' is similar to the connection relationship between clamp structure 100' and seat 211'. The following mainly describes the differences between the two.

[0125] See Figure 13-15 The rotating rod 110'' is rotatably connected to the backrest 221'. The clamp rod 120'' can rotate with the rotating rod 110'' relative to the backrest 221' between a first position and a second position. When the clamp rod 120'' is in the first position, the engaging member 130' can be detachably engaged with the backrest 221', thereby locking or unlocking the rotation of the clamp rod 120'' relative to the backrest 221'. When the clamp rod 120'' is in the second position, the belt can be inserted into or removed from the clamping part 128''. When the belt is inserted into the clamping part 128'' and the clamp rod 120'' rotates from the second position to the first position, the clamp rod 120'' tensions and compresses the belt through the clamping part 128''.

[0126] The backrest 221' is provided with a rotating rod receiving groove 201'', a rotating rod mounting hole 202'', a clamping part receiving groove 203'', a third rod receiving groove 204'', a locking part receiving groove 205'', and a limiting clamping block 215''. The arrangement of the rotating rod receiving groove 201'', the rotating rod mounting hole 202'', the clamping part receiving groove 203'', the third rod receiving groove 204'', the locking part receiving groove 205'', and the limiting clamping block 215'', and their cooperation with the clamping structure 100'', are described above and will not be repeated here.

[0127] The engaging component 130'' includes an engaging body 131'', a locking part 132'', and an engaging body reset part 134''. The engaging body 131'' is provided with a limiting hole 1312'' and a clearance groove 1313''. The engaging body 131'' is fixedly connected to the third rod part 123'' via a limiting pin 133''. The locking part 132'' is provided with a locking protrusion 1321''. For the details of the engaging body 131'', locking part 132'', limiting pin 133'', engaging body reset part 134'', limiting hole 1312'', clearance groove 1313'', and locking protrusion 1321'', as well as their connection relationship with the clamp rod 120', please refer to the relevant description of the engaging component 130' above, which will not be repeated here.

[0128] A locking element 213'' is provided on the back of 221'. The bottom wall of the locking element 213'' and the engaging element receiving groove 205'' together define the locking part receiving groove 2012''. The locking element 213'' is also provided with a locking recess 2131''. For the configuration and mating relationship of the locking element 213'', the engaging element receiving groove 205'' and the locking part 132'', please refer to the relevant description of the engaging element 130' above, which will not be repeated here.

[0129] The locking piece 213'' is a locking tab located between the side wall of the reinforcing tube 240' and the reinforcing tube receiving groove 209' at the backrest 221'. The locking piece 213'' can be fixed to the reinforcing tube 240' located at the backrest 221'.

[0130] See Figure 20 and 21 In one embodiment, the seat body 2000' is mounted on the base 5000, and the tilt angle of the seat body 2000' relative to the base 5000 is adjustable. Specifically, the seat body housing 200' is mounted on the base housing 500, and the tilt angle of the seat body housing 200' relative to the base housing 500 is adjustable. The base housing 500 includes a top plate 510 for receiving the seat body housing 200'. The surface of the top plate facing the seat body housing 200' is a concave surface extending in the front-rear direction of the safety seat 1000', and the surface of the seat body housing 200' facing the base housing 500 is a convex surface matching the concave surface. The top plate 510 is provided with a guide groove 511 extending in the front-rear direction of the safety seat 1000'. The shape of the guide groove 511 extending in the front-rear direction of the safety seat 1000' is consistent with the shape of the concave surface extending in the front-rear direction of the safety seat 1000', that is, the guide groove 511 is an arc-shaped guide groove. The sliding piece 260 is fixedly disposed at the bottom of the seat body housing 200', inserted into the guide groove 511, and can slide along the guide groove 511, thereby slidably mounting the seat body housing 200' onto the top plate 510. When the seat body housing 200' slides along the guide groove 511 in the front-to-back direction, the tilt angle of the seat body housing 200' relative to the base housing 500 can change.

[0131] Furthermore, the base housing 500 includes side plates 520 extending from the left and right sides of the top plate 510 in a direction away from the seat body housing 200'. The sliding piece 260 includes a guide groove 511 extending from the side opposite to the seat body housing 200', extending towards the side plate 520, and forming an indicator piece 262 disposed opposite to the side plate 520. The side plate 520 is provided with a plurality of display holes 521 arranged in the front-rear direction of the safety seat 1000'. The position of the indicator piece 262 corresponds to the position of the plurality of display holes 521, such that when the seat body housing 200' slides along the guide groove 511, the indicator piece 262 can sequentially align with each of the plurality of display holes 521. The seat body housing 200' slides along the guide groove 511 to different positions such that when the indicator piece 262 slides to align with different display holes 521, the seat body housing 200' has different tilt angles relative to the base housing 500. Thus, multiple display holes 521 can represent different tilt positions, which represent different tilt angles of the seat body housing 200' relative to the base housing 500. When the user adjusts the tilt angle of the seat body housing 200' relative to the base housing 500, if the indicator 262 is seen through the indicator hole 521 indicating the desired tilt position, it means that the seat body housing 200' has slid to the corresponding tilt position. In this way, the user can easily adjust the tilt angle of the seat body housing 200'. The indicator 262 can be colored, for example, painted, so that the user can observe the position of the indicator 262.

[0132] Figure 22 A perspective view of a safety seat 1000A according to a third embodiment of the present invention is shown. The safety seat 1000A includes a seat body 2000A and a base (see base 5000 of the second embodiment). The seat body 2000A has a seat body housing 200A. The base has a base housing. The safety seat 1000A also includes clamp structures 100A and 100B. The clamp structures 100A or 100B can be mounted on the seat body housing 200A or on the base housing. The following description uses the example of clamp structures 100A and 100B mounted on the seat body housing 200A to illustrate the safety seat 1000A.

[0133] Please see Figure 22The seat body shell 200A includes a seat portion 210A, a backrest portion 220A, and a headrest portion 230A. The seat portion 210A includes a seat portion 211A and seat side portions 212A extending upwards on opposite sides of the seat portion 211A. The backrest portion 220A includes a backrest 221A and backrest side portions 222A extending forward on opposite sides of the backrest 221A. The seat side portions 212A of the seat portion 210A and the backrest side portions 222A of the backrest portion 220A form the sides of the seat body shell 200A. The arrangement, connection relationship, and function of the seat portion 210A, backrest portion 220A, and headrest portion 230A can be referred to the arrangement, connection relationship, and function of the seat portion 210, backrest portion 220, and headrest portion 230 in the first embodiment of the present invention, and will not be repeated here.

[0134] The seat body housing 200A also includes a reinforcing tube 240A extending from the backrest 221A to the seat portion 211A to enhance the strength of the seat body housing 200A, thereby improving its service life. More specifically, the seat body housing 200A includes a reinforcing tube receiving groove 209A disposed between the backrest 221A and the seat portion 211A, and between two sides of the seat body housing 200A. The reinforcing tube 240A is received within the reinforcing tube receiving groove 209A.

[0135] The child safety seat 1000A may include a forward-facing clamp structure 1001A and a rearward-facing clamp structure 1002A. The forward-facing clamp structure 1001A and the rearward-facing clamp structure 1002A are respectively used to secure the child safety seat 1000A to the vehicle seat in the forward-facing and rearward-facing usage modes. Specifically, the forward-facing clamp structure 1001A is disposed on the backrest 221A, and each of the two backrest sides 222A has a forward through hole 2221A; the rearward-facing clamp structure 1002A is disposed on the seat portion 211A, and each of the two seat sides 212A has a rearward through hole 2121A. The arrangement, cooperation relationship and function of the forward clamp structure 1001A, the rear clamp structure 1002A, the forward through hole 2221A and the rear through hole 2121A can be referred to the arrangement, cooperation relationship and function of the forward clamp structure 1001, the rear clamp structure 1002, the forward through hole 2221 and the rear through hole 2121 in the first embodiment of the present invention, and will not be repeated here.

[0136] In one embodiment, the forward clamp structure 1001A adopts the clamp structure 100B provided according to the third embodiment of the present invention, and the backward clamp structure 1002A adopts the clamp structure 100A provided according to the third embodiment of the present invention. The clamp structure 100A provided in the third embodiment of the present invention will be described in detail below.

[0137] See Figure 23The clamp structure 100A includes a rotating rod 110A, a clamping rod 120A, a locking component 130A, a reinforcing plate 140A, and a clamping block 150A. (See reference...) Figures 29 to 32 The rotating rod 110A is rotatably connected to the seat 211A relative to the seat portion 211A. The rotating rod 110A extends substantially parallel to the seat surface 2110A of the seat portion 211A. The rotating rod 110A can rotate relative to the seat portion 211A about its central axis. Specifically, the seat portion 211A is provided with a rotating rod receiving groove 201A, and a rotating rod mounting hole 202A is provided on one end wall of the rotating rod receiving groove 201A. The rotating rod 110A is received in the rotating rod receiving groove 201A, and one end of the rotating rod 110A is rotatably inserted into the rotating rod mounting hole 202A, thereby making the rotating rod 110A rotatably connected to the seat portion 211A relative to the seat portion 211A. In one embodiment, a limiting clamping block, similar to that in the first embodiment, is fixedly connected to the seat 211A above the rotating rod receiving groove 201A and near the other end of the rotating rod 110A, to prevent the rotating rod 110 from disengaging from above the rotating rod receiving groove 201A. In another embodiment, the other end wall of the rotating rod receiving groove 201A is provided with another rotating rod mounting hole 202A, and the other end of the rotating rod 110A is rotatably inserted into the other rotating rod mounting hole 202A. It should be understood that the rotating rod 110A can also be rotatably connected to the seat 211A in other ways, and this is not limited herein.

[0138] See Figure 23 and Figures 29 to 32 The clamp rod 120A is fixedly connected to the rotating rod 110A and can rotate with the rotating rod 110A relative to the seat 211 in the first position ( Figure 30 ) and second position ( Figure 32 The clamp rod 120A has a clamping portion 128A through which the belt body passes. When the belt body is inserted into the clamping portion 128A and the clamp rod 120A rotates from the second position to the first position, the clamp rod 120A tensions and compresses the belt body through the clamping portion 128A. Specifically, when the belt body passes through a rear through hole 2121A, the clamping portion 128A of the clamp rod 120A, and another rear through hole 2121A in sequence and is connected to the fastener on the vehicle seat, the user can rotate the clamp rod 120A from the second position to the first position. During this process, the rotation of the clamping portion 128A causes a portion of the belt body inserted therein to wrap around the clamping portion 128A, thereby tensioning the entire belt body. When the clamp rod 120A reaches the first position, the clamp rod 120A presses the tensioned belt body onto the seat portion 211A, at which point the belt body can be secured to the safety seat 1000A. When the clamp rod 120A is in the second position, the belt can be inserted into or removed from the clamping part 128A.

[0139] In one embodiment, the clamping rod 120A includes a first rod portion 121A, a second rod portion 122A, and a third rod portion 123A connected in sequence. The first rod portion 121A and the second rod portion 122A form a clamping portion 128A through which the belt body passes. The structure of the rotating rod 110A, the first rod portion 121A, the second rod portion 122A, the third rod portion 123A, and the clamping portion 128A, as well as their connections and cooperation relationships, can be referred to the structure of the rotating rod 110, the first rod portion 121, the second rod portion 122, the third rod portion 123, and the clamping portion 128A in the first embodiment of the present invention, as well as their connections and cooperation relationships, and will not be repeated here.

[0140] See Figures 23 to 28 A reinforcing plate 140A covers the rotating rod 110A and the clamping rod 120A to provide protection for them. Specifically, the reinforcing plate 140A includes a first reinforcing portion 141A and a second reinforcing portion 142A that are interconnected. The first reinforcing portion 141A extends substantially parallel to the rotating rod 110A and covers the rotating rod 110A and the clamping portion 128A. The second reinforcing portion 142A extends substantially parallel to the third rod portion 123A and covers the third rod portion 123A. In the illustrated embodiment, the first reinforcing portion 141A and the second reinforcing portion 142A are integrally connected. It should be understood that in other embodiments, the first reinforcing portion 141A and the second reinforcing portion 142A may also be two separate components and fixedly connected by means of adhesive, fasteners, or other methods.

[0141] See also Figures 29 to 32 The reinforcing plate 140A is fixedly connected to the rotating rod 110A and / or the clamping rod 120A, and can rotate with the clamping rod 120A relative to the seat portion 211 between a first position and a second position. When the clamping rod 120A is in the first position, the reinforcing plate 140A is located on the side of the rotating rod 110A and the clamping rod 120A opposite to the seat surface 2110A of the seat portion 211A, and extends substantially parallel to the seat surface 2110A of the seat portion 211A. Further, when the clamping rod 120A is in the first position, the rotating rod 110A and the clamping part 128A are located directly below the first reinforcing part 141A and are blocked by the first reinforcing part 141A, while the third rod part 123A is located directly below the second reinforcing part 142A and is blocked by the second reinforcing part 142A.

[0142] In one embodiment, the seat portion 211A is further provided with a clamping portion receiving groove 203A communicating with the rotating rod receiving groove 201A. When the clamping rod 120A is in the first position, the first rod portion 121A and the second rod portion 121B, as well as the clamping portion 128A formed therethere, are located in the clamping portion receiving groove 203A. A third rod portion receiving groove 1421A is provided on the side of the second reinforcing portion 142A facing the clamping rod 120A (see...). Figure 25 The third rod portion 123A is accommodated in the third rod portion receiving groove 1421A. Thus, when the clamp rod 120A is in the first position, the entire clamp rod 120A is essentially shielded and protected by the reinforcing plate 140A. It should be understood that in other embodiments, the third rod portion receiving groove can also be provided on the seat portion 211A as in the first embodiment. When the clamp rod 120A is in the first position, the third rod portion 123A can be accommodated in this third rod portion receiving groove and shielded by the second reinforcing portion 142A, achieving the same effect of protecting the third rod portion 123A.

[0143] See Figures 23 to 28 The clamping block 150A is sleeved on the first rod portion 121A. Specifically, the clamping block 150A is provided with a sleeve hole 151A, through which the clamping block 150A is sleeved on the first rod portion 121A. A closing portion 152A is provided at the end of the clamping block 150A near the open end of the clamping portion 128A. The clamping block 150A can be in a closed position relative to the clamping portion 128A (…). Figure 27 ) and open location ( Figure 26 The clamping block 150A rotates between the clamping and opening positions. In the closed position, the closing part 152A is located at the opening end of the clamping part 128A to prevent the belt in the clamping part 128A from disengaging from the opening end of the clamping part 128A. In the open position, the closing part 152A moves away from the opening end of the clamping part 128A, thereby allowing the belt to pass through the opening end of the clamping part 128A. When the clamping lever 120A is in the first position, the clamping block 150A is in the closed position. When the clamping lever 120A is in the second position, the clamping block 150A is in the open position. It should be noted that in the... Figures 26 to 28 In this context, the X direction corresponds to a first direction parallel to the seat surface 2110A of the seat portion 211A; the Y direction corresponds to a second direction parallel to the seat surface 2110A of the seat portion 211A, the second direction being, for example, perpendicular to the first direction; and the Z direction corresponds to a direction perpendicular to the seat surface 2110A of the seat portion 211A. Therefore, Figure 26 Although the clamp rod 120A is shown in a horizontal orientation, it corresponds to the configuration when the clamp rod 120A is in the second position.

[0144] In some embodiments, the belt can be threaded between the first rod portion 121A and the second rod portion 121B along a first direction (e.g., the X direction). In some embodiments, when the clamping rod 120A is in the second position, the belt can enter the clamping portion 128A from the opening end of the clamping portion 128A along a second direction (e.g., the Y direction). In some embodiments, when the clamping rod 120A is in the first position, the first rod portion 121A and the second rod portion 121B can be arranged along a third direction (e.g., the Z direction).

[0145] In one embodiment, the reinforcing plate 140A further includes a third reinforcing portion 143A extending from the first reinforcing portion 141A and / or the second reinforcing portion 142A above the closing portion 152A. In the closed position, the abutting portion 151A abuts against the third reinforcing portion 143A, thereby closing the opening end of the clamping portion 128A together with the abutting portion 151A to prevent the belt located in the clamping portion 128A from dislodging. In the open position, the abutting portion 151A separates from the third reinforcing portion 143A, thereby allowing the belt to pass through the opening end of the clamping portion 128A. Further, when the clamping rod 120A is in the first position, the clamping block 150A is also located in the clamping portion receiving groove 203A, and the closing portion 152A is clamped between the third reinforcing portion 143A and the bottom wall of the clamping portion receiving groove 203A, such that the clamping block 150A is held in the closed position.

[0146] See Figure 23 and Figure 25 In one embodiment, a clamping block reset member 160A is further provided between the clamping block 150A and the first rod portion 121, and the clamping block reset member 160A biases the clamping block 150A toward the open position. When the clamping structure 100A is in the second position, the clamping block 150A moves away from the clamping portion receiving groove 203A along with the first rod portion 121, and is held in the open position under the biasing force of the clamping block reset member 160A. In the illustrated embodiment, the clamping block reset member 160A is a torsion spring, a fixing protrusion 1211A is provided on the first rod portion 121A, the torsion spring is sleeved on the first rod portion 121A, and one torsion arm of the torsion spring is fixed to the fixing protrusion 1211A, while the other torsion arm abuts against the sleeve hole 151A to bias the clamping block 150A toward the open position. It should be understood that the implementation of the clamping block reset member 160A is not limited to this, as long as a biasing force toward the open position can be applied to the clamping block 150A.

[0147] See also Figure 26 , Figure 27 and Figure 30 In one embodiment, the reinforcing plate 140A further includes a fourth reinforcing portion 144A extending downward from the first reinforcing portion 141A to the end of the clamping block 150A away from the open end of the clamping portion 128A and abutting against that end. When the clamping structure 100A is in the first position, both ends of the clamping block 150A abut against the end walls of the fourth reinforcing portion 144A and the clamping portion receiving groove 203A, respectively, thereby retaining the clamping block 150A in the clamping portion receiving groove 203A.

[0148] See Figures 23 to 28The engaging member 130A is disposed at the end of the clamping rod 120A away from the rotating rod 110A. When the clamping rod 120A is in the first position, the engaging member 130A can be detachably engaged with the seat portion 211A, thereby locking or unlocking the rotation of the clamping rod 120A relative to the seat portion 211A. In a specific embodiment, the engaging member 130A may be disposed at the end of the second reinforcing portion 142A away from the rotating rod 110A, and located on the side of the second reinforcing portion 142A opposite to the third rod portion 123A. The engaging member 130A has an engaging groove 1301A on the side facing the third rod portion 123A (see...). Figure 25 The end of the second reinforcing part 142A away from the rotating rod 110A is slidably engaged in the engaging groove 1301A, so that the engaging part 130A can move relative to the second reinforcing part 142A between a locked position and an unlocked position.

[0149] See also Figure 30 and Figure 32 In one embodiment, the engaging member 130A has a locking end 132A, and a matching member 213A is provided on the seat portion 211A. The matching member 213A and the seat portion 211A together define a locking end receiving groove 2012A. When the clamping rod 120A is in the first position, when the engaging member 130A is in the locked position, the locking end 132A extends into the locking end receiving groove 2012A, and the matching member 213A restricts the locking end 132A and the clamping rod 120A from rotating relative to the seat portion 211A. When the engaging member 130A is in the unlocked position, the locking end 132A exits from the locking end receiving groove 2012A, thereby allowing the locking end 132A and the clamping rod 120A to rotate relative to the seat portion 211A. Furthermore, a locking protrusion 1321A is provided on the locking end 132A, and a locking recess 2131A is provided on the locking member 213A. When the locking end 132A extends into the locking end receiving groove 2012A, the locking protrusion 1321A and the locking recess 2131A engage together to restrict the sliding of the locking end 132A and the engaging member 130A relative to the second reinforcing part 142A, thereby preventing the locking end 132A from exiting the locking end receiving groove 2012A.

[0150] See Figure 30 and Figure 32 In one embodiment, the card-mounting member 213A includes a first card-mounting portion 2132A extending substantially perpendicular to the seat surface 2110A of the base portion 211A, and a second card-mounting portion 2133A extending substantially parallel to the seat surface 2110A of the base portion 211A toward the rotating rod 110A from the top of the first card-mounting portion 2132A toward the rotating rod 110A. The first card-mounting portion 2132A, the second card-mounting portion 2133A, and the base portion 211A together define a locking end receiving groove 2012A. A locking recess 2131A is provided on the second card-mounting portion 2133A. Further, see also Figure 22The first card-mounting part 2132A of the card-mounting component 213A is disposed between the sidewalls of the reinforcing tube 240A and the reinforcing tube receiving groove 209A. The first card-mounting part 2132A is, for example, fixed to the reinforcing tube 240A.

[0151] See Figure 23 and Figure 24 In one embodiment, the locking end 132A has an upper end face 1322A extending substantially parallel to the third rod portion 123A and a lower end face 1323A extending obliquely from the end of the upper end face 1322A toward the rotating rod 110A, and a locking protrusion 1321A is provided on the upper end face 1322A. See also... Figure 32 When the locking protrusion 1321A and the locking recess 2131A engage, a pressing space is formed between the lower end face 1323A and the bottom wall of the locking end receiving groove 2012A (i.e., between the lower end face 1323A and the seat portion 211). By pressing the locking end 132A downwards, the locking protrusion 1321A can be disengaged from the locking protrusion 1321A. Further, see [reference needed]. Figure 23 The locking protrusion 1321A has a limiting surface 1324A and a pushing surface 1325A. The limiting surface 1324A is substantially perpendicular to the upper end surface 1322A. The pushing surface 1325A is inclined from the top of the limiting surface 1324A in a direction away from the rotating rod 110A. When the engaging member 130A moves away from the rotating rod 110A relative to the third rod portion 123A (i.e., moves towards the locked position), the locking protrusion 1321A slides into the locking recess 2131A through the pushing surface 1325A. When the locking protrusion 1321A and the locking recess 2131A are engaged together, the limiting surface 1324A abuts against the side wall of the locking recess 2131A to restrict the engaging member 130A from moving towards the rotating rod 110A relative to the third rod portion 123A (i.e., moving towards the unlocked position).

[0152] It should be understood that in other embodiments, a locking recess may be provided on the locking end 132A, and a locking protrusion may be provided on the card fitting 213A.

[0153] See Figures 26 to 28 In one embodiment, the reinforcing plate 140A further includes a limiting portion 145A extending substantially parallel to the rotating rod 110A from the second reinforcing portion 142A, the limiting portion 145A being disposed between the rotating rod 110A and the engaging member 130A; see also Figure 31 as well as Figure 32 A limiting groove 2111A extending substantially parallel to the rotating rod 110A may be provided at the corresponding position of the seat 211. When the clamp rod 120A is in the first position ( Figure 31The limiting portion 145A engages in the limiting groove 2111 to restrict the movement of the second reinforcing portion 142A relative to the engaging member 130A. Thus, the limiting portion 145A, the limiting groove 2111, and the locking protrusion 1321A and locking recess 2131A form a double limiting of the engaging member 130A and the second reinforcing portion 142A, to more securely hold the clamping rod 120A in the first position. Furthermore, the limiting portion 145A can extend downward from the end of the fourth reinforcing portion 144A away from the rotating rod 110A, and the limiting groove 2111 can be provided on the side of the clamping portion receiving groove 203A away from the rotating rod 110A, thereby making the structure of the reinforcing plate 140A more compact and simple.

[0154] See Figure 25 and Figure 28 In one embodiment, a locking member reset member 134A is further provided between the locking member 130A and the second reinforcing portion 142A. The locking member reset member 134A provides a biasing force to bias the locking member 130A toward the locked position. In the illustrated embodiment, the locking member 130A has a reset member receiving groove 1302A and a first protrusion 1303A on the side facing the second reinforcing portion 142A. The first protrusion 1303A is located at one end of the reset member receiving groove 1302A and protrudes toward the second reinforcing portion 142A. The second reinforcing portion 142A has a second protrusion 1421A on the side facing the locking member 130A (see...). Figure 23 The second protrusion 1421A is located at the other end of the reset member receiving groove 1302A and protrudes toward the engaging member 130A. The engaging member reset member 134A is a spring, which is received in the reset member receiving groove 1302A, and its two ends abut against the first protrusion 1303A and the second protrusion 1421A, respectively. It should be understood that the arrangement of the engaging member reset member 134A is not limited to this, as long as it can provide a biasing force toward the locked position to the engaging member 130A.

[0155] See Figure 23 and Figure 25In one embodiment, a limiting hole 1422A is provided on the second reinforcing portion 142A. A limiting pin 133A passes through the limiting hole 1422A and is fixedly connected to the engaging member 130A, for example, by being threaded to a fastening hole 1304A of the engaging member 130A. The limiting hole 1422A is an elongated hole extending in a direction parallel to the extension of the second reinforcing portion 142A. The two ends of the limiting hole 1422A cooperate with the limiting pin 133A to limit the sliding stroke of the engaging member 130A relative to the second reinforcing portion 142A. Furthermore, the second reinforcing portion 142A is also connected to the engaging member 130A by another fastener 136. Specifically, the second reinforcing part 142A is provided with another elongated hole 1423A extending in a direction parallel to the extension of the second reinforcing part 142A. Another fastener 136 passes through the other elongated hole 1423A and is fixedly connected to the engaging part 130A. The length of the other elongated hole 1423A may be equal to or greater than the length of the limiting hole 1422A, so as not to hinder the sliding of the engaging part 130A relative to the second reinforcing part 142A within its sliding stroke. Through the cooperation of the limiting pin 133A and the other fastener 136, the connection between the engaging part 130A and the second reinforcing part 142A and their relative sliding can be made more stable. It should be understood that in other embodiments, the limiting hole 1422A and / or the other elongated hole 1423A may also be provided on the engaging part 130A, and the limiting pin 133A and / or the other fastener 136 may pass through the limiting hole 1422A and / or the other elongated hole 1423A and be fixedly connected to the second reinforcing part 142A.

[0156] See Figure 28 In one embodiment, a portion of the first reinforcing portion 142A extends beyond the end of the third rod portion 123A away from the rotating rod 110A, and a limiting hole 1422A and / or another elongated hole 1423A are provided on this portion of the first reinforcing portion 142A, so that the third rod portion 123A does not obstruct the connection between the limiting pin 133A and / or another fastener 136 and the engaging member 130A.

[0157] See Figure 23 In one embodiment, the engaging member 130A is further provided with an operating groove 1305A and / or an embossed pattern 1306A on the side away from the second reinforcing part 142A to facilitate the user's movement of the engaging member 130A. The embossed pattern 1306A may be provided on the side of the operating groove 1305A near the rotating rod 110A. More specifically, the embossed pattern 1305A and the locking protrusion 1321A may be located on opposite sides of the operating groove 1305A.

[0158] It should be understood that, in embodiments not shown, the reinforcing plate 140A may be omitted. In this case, when the clamping block 150A is in the closed position, the abutment portion 151A abuts against the second rod portion 121A of the clamping portion 128A, thereby closing the open end of the clamping portion 128A. When the clamping block 150A is in the open position, the abutment portion 151A separates from the second rod portion 121A, thereby opening the open end of the clamping portion 128A. When the clamping rod 120A is in the first position, the clamping block 150A can be held in the closed position by the limiting action of the second rod portion 121A and the side wall of the clamping portion receiving groove 203A. When the clamping rod 120A is in the second position, the clamping block 150A can be held in the open position by the action of the clamping block reset member 160A.

[0159] In another embodiment (not shown), the rotating rod 110A or the second rod portion 121A may also be provided with another abutting portion, the position and structure of which are similar to the third reinforcing portion 143A, replacing the third reinforcing portion 143A. This other abutting portion may be integrally formed with the rotating rod 110A or the second rod portion 121A, or it may be a separate component mounted on the rotating rod 110A or the second rod portion 121A.

[0160] The clamp structure 100B and clamp structure 100A are roughly the same, and will not be described in detail here. Correspondingly, the backrest 211A is provided with a rotating rod receiving groove, a rotating rod mounting hole, a clamping part receiving groove, a limiting groove, and a matching piece corresponding to the rotating rod receiving groove 201A, the rotating rod mounting hole 202A, the clamping part receiving groove 203A, the limiting groove 2111A, and the matching piece 213A. Their arrangement can be found in the description of clamp structure 100A, and will not be described in detail here.

[0161] It should be understood that clamp structure 100A and clamp structure 100B may have the same or different dimensions. Clamp structure 100A and clamp structure 100B may be used simultaneously, or one of clamp structure 100A and clamp structure 100B may be replaced by another clamp structure.

[0162] The following describes the operation of the clamp structure 100A.

[0163] When the user needs to secure the safety seat 1000A to the vehicle seat in a rearward manner, the user can press down on the locking end 132A and simultaneously push the engaging member 130A towards the first reinforcing part 141A, then rotate the second reinforcing part 142A upward, so that the clamp lever 120A is in the second position. At this time, the clamping block 150A is in the open position under the action of the clamping block reset member 160A, and the user can insert the strap into the clamping part 128A. Then, the user rotates the second reinforcing part 142A downward, so that a part of the strap is wrapped around the clamping part 128A, thereby tensioning the entire strap. When the clamp lever 120A is rotated to the first position, the user can push the engaging member 130A away from the first reinforcing part 141A, or under the biasing force provided by the engaging member reset member 134A that biases the engaging member 130A towards the locking position, the clamp lever 120A can be locked in the first position, thus securing the safety seat 1000A to the vehicle seat.

[0164] The operation of clamp structure 100B is roughly the same as that of clamp structure 100A, and will not be described in detail here.

[0165] 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.
