It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present application.

[0058] The following further elaborates on this application in conjunction with the attached drawings. Refer to, for example, Figures 1 to 8 for the description.

[0059] This application provides a child safety seat for use by infants. As shown in, for example, Figure 1 , Figure 2 it includes a housing, a handle, a backrest support 12, and a leg support 13. The handle is in an 'n' shape and spans above the opening of the housing, with both ends of the handle connected to both sides of the housing. The backrest support 12 and the leg support 13 are provided on the upper surface of the opening of the housing. Among them, the backrest support 12 and the leg support 13 are arranged along the lying direction of the housing. One end of the leg support 13 is rotatably connected to the housing, and the other end is connected to the backrest support 13. Moreover, the backrest support 12 is located above the leg support 13, and the backrest support 12 and the leg support 13 at least partially overlap. The end of the leg support 13 away from the backrest support 12 is rotatably connected to the housing. Among them, in this application, an adjustment mechanism 14 is also provided. The adjustment mechanism 14 is arranged at the connection between the backrest support 12 and the leg support 13. The backrest support 12 is movably connected to the leg support 13 through the adjustment mechanism 14. The adjustment mechanism 14 is used to adjust the connection angle between the backrest support 12 and the leg support 13, thereby changing the lying posture of the child safety seat 1, enabling the child safety seat 1 to have multiple lying postures, so as to improve the use comfort and flexibility of the child safety seat 1.

[0060] Specifically, as shown in, for example, Figures 1 to 4 the adjustment mechanism 14 includes an adjustment seat 141 and an adjustment member 142. The adjustment seat 141 is connected to the end face of the backrest support 12 facing the leg support 13. The adjustment seat 141 is fixedly connected to or integrally formed with the backrest support 12, and the adjustment seat 141 is movably connected to the leg support 13. As shown in, for example, Figure 6As shown, there are two adjusting seats 141, which are respectively located at both ends of the back support seat 12; the adjusting member 142 is connected to the back support seat 12 through the adjusting seat 141, and the end of the adjusting member 142 away from the back support seat 12 is movably connected to the housing. Among them, when the child safety seat 1 is placed on a horizontal plane, the height of the connection between the adjusting member 142 and the housing is higher than the height of the connection between the adjusting member 142 and the back support seat 12. By pulling the adjusting member 142 at the connection with the housing, the back support seat 12 can be driven to displace in the vertical direction, and then through the connection between the adjusting seat 141 and the leg support seat 13, the leg support seat 13 is driven to move in the vertical direction. Since the ends of the back support seat 12 and the leg support seat 13 away from the adjusting mechanism 14 are rotatably connected to the housing, when the height of the connection ends of the back support seat 12 and the leg support seat 13 with the adjusting mechanism 14 changes in the vertical direction, the angle between the back support seat 12 and the leg support seat 13 changes, so that the child safety seat 1 can achieve different lying postures for the convenience of children's use.

[0061] In another alternative embodiment of the present application, the adjusting mechanism 14 is further described; as Figures 3 to 6 shown, the adjusting seat 141 is basically a triangular structure; a limiting slide bar 143 is provided at the lower end of the adjusting seat 141, and both ends of the limiting slide bar 143 are respectively connected to the two adjusting seats 141. An installation space is formed between the limiting slide bar 143 and the bottom surface of the back support seat 12, and this installation space is used for the leg support seat 13 to be inserted, so as to relatively limit the leg support seat 13 and the back support seat 12 to prevent the leg support seat 13 from separating from the back support seat 12; among them, the limiting slide bar 143 is rotatably connected to the adjusting seat 141. As Figure 3 、 Figure 7 shown, an adjusting chute 131 is provided on the leg support seat 13, and the adjusting chute 131 opens towards the direction of the limiting slide bar 143. The adjusting chute 131 is in contact with the limiting slide bar 143, and the length extension direction of the adjusting chute 131 is the same as the length extension direction of the leg support seat 13. The limiting slide bar 143 can slide along the adjusting chute 131; when the height of the back support seat 12 driven by the adjusting member 142 changes in the vertical direction, the fitting position between the limiting slide bar 143 and the adjusting chute 131 changes, and the overlapping area between the leg support part and the back support part changes. At the same time, due to the limitation of the leg support seat 13 by the limiting slide bar 143, the angle between the leg support part and the back support part changes, so as to realize the adjustment of different lying postures of the child safety seat 1.

[0062] Among them, as Figure 3 、 Figure 4As shown, limiting blocks 132 are provided at both ends of the adjusting chute 131. The limiting blocks 132 protrude towards the limiting slide rod 143. The protruding length of the limiting blocks 132 is greater than the thickness of the limiting slide rod 143, so that the limiting blocks 132 can limit the sliding length of the limiting slide rod 143 on the adjusting chute 131, preventing the limiting slide rod 143 from disengaging during sliding along the adjusting chute 131, and ensuring the safety of the angle adjustment of the child safety seat 1. In this application, taking the lying direction of the child safety seat 1 as the front-back direction, the length extension direction of the adjusting chute 131 is arranged along the front and back directions of the child safety seat 1, and the limiting blocks 132 are arranged at the front and back ends of the adjusting chute 131.

[0063] Further, as Figure 3 , Figure 4 , Figure 6 shown, a belt-passing portion 1411 through which the adjusting member 142 passes is provided on the adjusting seat 141. The belt-passing portion 1411 is open on both side walls of the adjusting seat 141, so that the adjusting member 142 can pass through; in this embodiment, the two side walls of the adjusting seat 141 are in the left-right direction, that is, the belt-passing portion 1411 is open on the end faces of the left and right side walls of the adjusting seat 141, so that the adjusting member 142 is arranged along the left-right direction at the lower end of the back support seat 12; in this embodiment, the adjusting member 142 is in a long strip shape or a rope shape. The two end joints of the adjusting member 142 respectively pass through the two adjusting seats 141 and are movably connected to the housing. Among them, a belt-passing opening 111 is provided on the housing, and the belt-passing opening 111 is located above the adjusting seat 141. In this embodiment, the belt-passing opening 111 is located at the upper end of the housing; the belt-passing opening 111 is open on the inner and outer side walls of the housing, so that after the adjusting member 142 passes through the belt-passing opening 111 inside the housing, it is exposed to the outside of the housing, so that the adjusting member 142 can be pulled outside the child safety seat 1 to adjust the lying angle of the child safety seat 1, which is convenient for the user to operate.

[0064] Among them, as Figure 3 , Figure 4 , Figure 6 shown, the belt-passing portion 1411 is located between the back support seat 12 and the limiting slide rod 143, that is, the adjusting member 142 is located between the back support seat 12 and the leg support seat 13, so that the adjusting member 142 only acts on the back support seat 12. The adjusting member 142 can drive the back support seat 12 to move up and down, and the displacement of the leg support seat 13 is driven by the common cooperation of the limiting slide rod 143 and the back support seat 12, ensuring the uniqueness of the force transmission and reducing interference.

[0065] It should be noted that in this embodiment, the adjusting member 142 is slidably connected to the adjusting seat 141, and the adjusting member 142 can slide in the belt-passing portion 1411. In another alternative embodiment, the adjusting member 142 can also be fixedly connected to the adjusting seat 141.

[0066] Based on the above embodiments, the adjustment seat 141 is further expanded; for example Figure 3 , Figure 4 , Figure 6 As shown, an installation part 1412 is further provided on the adjustment seat 141, and the installation part 1412 is open on the left and right side wall end faces of the adjustment seat 141; wherein, the installation part 1412 includes a first open end and a second open end, the first open end is communicated with the bottom of the belt passing part 1411, and the second open end is open on the end face of the adjustment seat 141 facing the leg support seat 13, that is, the installation part 1412 is arranged in the front-back direction as a whole, the first open end is the rear end of the installation part 1412, the second open end is the front end of the installation part 1412, and the second open end is open at the front end of the adjustment seat 141, so as to form a belt passing gap, so that the adjusting member 142 can move from the second open end towards the first open end direction, so as to insert the adjusting member 142 into the belt passing part 1411 to realize the installation of the adjusting member 142 and the adjustment seat 141.

[0067] Further, as Figure 3 , Figure 6 shown, the included angle between the belt passing direction of the belt passing part 1411 and the belt passing direction of the installation part 1412 is an acute angle, so as to prevent the adjusting member 142 from slipping into the installation part 1412 during the sliding process; and, the first open end is arranged at the rear end position of the belt passing part 1411, that is, the connection part of the installation part 1412 and the belt passing part 1411 is eccentrically arranged at the rear end of the belt passing part 1411, which can further reduce the probability of the adjusting member 142 slipping out of the installation part 1412. Among them, the installation part 1412 is located between the limit slide bar 143 and the belt passing part 1411, that is, the belt passing part 1411 is located above the installation part 1412, and the installation part 1412 is located above the limit slide bar 143.

[0068] As Figure 6 shown, the side walls of the belt passing part 1411 in contact with the adjusting member 142 are all set as smooth arc surfaces, which can reduce the wear on the adjusting member 142 and make the movement between the adjusting member 142 and the adjustment seat 141 smoother; wherein, the opening of the belt passing part 1411 on the end face facing the housing is larger than the opening of the belt passing part 1411 on the end face facing away from the housing, that is, the opening of the belt passing part 1411 on the end face facing the housing is a flared opening, so that when the user pulls the adjusting member 142, it has more flexible adjustability and avoids the adjusting member 142 being stuck with the adjustment seat 141 and affecting the adjustment effect.

[0069] Based on the above embodiments, the installation part 1412 is further expanded; for example Figure 3 , Figure 6As shown, the installation part 1412 is provided with an anti-slip groove 1412.1. The installation part 1412 includes a first side wall and a second side wall. The first side wall is arranged above the second side wall, and there is a space for the adjusting part 142 to pass through between the first side wall and the second side wall, that is, a gap for the adjusting part 142 to pass through is formed between the first side wall and the second side wall. Among them, the anti-slip groove 1412.1 is arranged at the middle position of the first side wall of the installation part 1412. The anti-slip groove 1412.1 opens on the upper and lower end faces of the first side wall, and the anti-slip groove 1412.1 opens on the side end of the first side wall facing the housing. Thus, when the adjusting part 142 slides out from the belt passing part 1411 towards the installation part 1412, the adjusting part 142 will fall into the anti-slip groove 1412.1, and the anti-slip groove 1412.1 will hold the adjusting part 142, preventing the adjusting part 142 from slipping out of the installation part 1412, thereby reducing the probability of the adjusting part 142 slipping off from the back support seat 12 and further improving the safety of the child safety seat 1.

[0070] The anti-slip groove 1412.1 opens on the side end of the first side wall facing the housing, which can facilitate the user to pull out the adjusting part 142 from the anti-slip groove 1412.1 and is convenient for operation.

[0071] Furthermore, as Figure 6 shown, there is an oblique guiding structure at the connection between the first opening end of the installation part 1412 and the belt passing part 1411. When the adjusting part 142 slides from the belt passing part 1411 into the installation part 1412, the oblique guiding structure will guide the adjusting part 142 into the anti-slip groove 1412.1, increasing the anti-detachment probability of the adjusting part 142.

[0072] Furthermore, as Figure 3 、 Figure 6 shown, a first anti-slip recess 1412.2 is provided on the first side wall. The first anti-slip recess 1412.2 recesses towards the direction away from the second side wall, that is, the first anti-slip recess 1412.2 recesses towards the bottom. The surface of the first anti-slip recess 1412.2 is a smooth arc surface. The first anti-slip recess 1412.2 is located between the anti-slip groove 1412.1 and the second opening end. Thus, the second opening end forms a protrusion relative to the first anti-slip recess 1412.2, which can further limit the displacement of the adjusting part 142 and can further prevent the adjusting part 142 from slipping out of the installation part 1412.

[0073] Among them, as Figure 3 、 Figure 6As shown in the figure, anti-slip recesses can also be provided on the second side wall. Specifically, a second anti-slip recess 1412.3 is provided on the second side wall. The second anti-slip recess 1412.3 is recessed in a direction away from the first side wall, that is, the second anti-slip recess 1412.3 is recessed upward. The surface of the second anti-slip recess 1412.3 is a smooth arc surface. The second anti-slip recess 1412.3 can correspond to the position of the first anti-slip recess 1412.2 or not. The second anti-slip recess 1412.3 can cooperate with the first anti-slip recess 1412.2 on the first side wall to improve the anti-disengagement property of the adjusting member 142.

[0074] On the basis of any of the above embodiments, the children's safety seat 1 of the present application is further expanded; as Figure 1 、 Figure 5 、 Figure 8 shown, the children's safety seat 1 further includes a locking mechanism 15. The locking mechanism 15 is provided outside the housing. The locking mechanism 15 is used to lock or unlock the adjusting member 142 with the housing, so that the locking mechanism 15 can lock the adjusting member 142, that is, lock the current lying posture of the children's safety seat 1, effectively improving the use safety of the applicable children's safety seat 1, and improving the convenience of the user to adjust the angle of the children's safety seat 1.

[0075] Specifically, as Figure 5 、 Figure 8 shown, the housing includes an inner housing 11 and an outer housing 16. The outer housing 16 is provided outside the outer housing 16. The belt passing opening 111 is provided on the inner housing 11. The locking mechanism 15 includes a locking base 151, a locking member 152 and a locking piece 153. The locking base 151 is connected to the outer side wall of the inner housing 11. A locking groove for installing the locking member 152 is provided on the locking base 151. The locking member 152 is connected to the locking base 151. A belt passing gap for the adjusting member 142 to pass through is provided between the locking member 152 and the locking base 151. The locking mechanism 15 is located below the belt passing opening 111. After passing through the belt passing opening 111, the adjusting member 142 passes through the belt passing gap and then passes through the belt passing gap and is connected to a pull ring 154. Among them, the locking piece 153 is movably connected to the outer housing 16. The locking piece 153 can displace in the left-right direction to press the locking member 152 or loosen the locking member 152, so as to change the size of the belt passing gap and realize the locking or unlocking of the adjusting member 142, facilitating the user to adjust the lying angle of the children's safety seat 1.

[0076] Further, as Figure 5 、 Figure 8As shown in the figure, the locking member 152 is rotatably connected to the locking base 151 through a rotating shaft. Meanwhile, the locking member 152 includes a pressing portion 1521 and an unlocking portion 1522. The pressing portion 1521 is located below the unlocking portion 1522, and the angle between the pressing portion 1521 and the unlocking portion 1522 is an obtuse angle; a pressing protrusion is provided at the end of the pressing portion 1521 facing the locking base 151, and the pressing protrusion contacts the adjusting member 142 to increase the pressing effect on the adjusting member 142; while the locking member 153 is correspondingly arranged at the position of the unlocking portion 1522. When the locking member 153 moves in the left-right direction, a force is applied to the unlocking portion 1522 or the force is released; as Figure 8 shown in the figure, when the locking member 153 applies a pressure to the unlocking portion 1522, the unlocking portion 1522 moves closer to the locking base 151, driving the pressing portion 1521 to rotate, and the belt-passing gap between the pressing portion 1521 and the locking base 151 expands. The locking mechanism 15 unlocks the locking member 153, and the user can pull the adjusting member 142 to adjust the angle of the child safety seat 1; when the locking member 153 moves outwards and contacts the pressure applied to the unlocking portion 1522, the unlocking portion 1522 rotates outwards, the pressing portion 1521 rotates inwards, and the belt-passing gap between the pressing portion 1521 and the locking base 151 decreases. The locking mechanism 15 locks the locking member 153 to ensure the stability of the current lying posture of the child safety seat 1 and ensure the safety of the baby using the child safety seat 1.

[0077] Among them, a torsion spring is provided in the locking member 152, so that the pressing portion 1521 always has a tendency to rotate inwards, so that the locking member 152 always has a tendency to lock the adjusting member 142, ensuring the stability of the child safety seat 1 and improving the safety. And, in this embodiment, the locking member 153 is formed by a button. Pressing the locking member 153 can realize the locking or unlocking of the adjusting member 142 by the locking mechanism 15, which greatly facilitates the operation of the user.
