Description

Technical Field

[0001] The utility model relates to the technical field of infant and toddler appliances, in particular to a child seat. Background Art

[0002] With the rapid development of the automotive industry and growing awareness of child safety in vehicles, child safety seats are becoming increasingly common. Currently, the two main child safety seat anchorage methods on the market are ISOFIX and LATCH. ISOFIX stands for "International Standards Organisation FIX," which means "International Organization for Standardization (Child Safety Seat) Anchorage." It is a standardized child safety seat interface design implemented in Europe since 1990, designed to make installation and removal of child seats quick and easy. Car seats using ISOFIX have two clips on the base, making installation extremely convenient. LATCH, short for Lower Anchors and Tethers for Children, is a mounting method specifically designed for child safety seats. Designed in accordance with relevant US government regulations, LATCH differs from ISOFIX in that, in addition to the two anchor points below the seat, it also has an additional anchor point above it, for a total of three anchor points. The LATCH system requires that the seat belt be connected to both the anchor point below and the anchor point above the seat to ensure the seat's stability while the vehicle is in motion.

[0003] In the LATCH system, the seat belt is one of the key components that connects the child safety seat to the car seat. These seat belts are usually made of high-strength materials and can withstand considerable tension and impact.

[0004] In the related art, when a vehicle stops suddenly, the seat belt will violently collide with its limiting hole under the influence of the child's torso. This may cause the structure related to the seat belt limiting hole to deform or be damaged, making it difficult to ensure the safety of the child seat. Utility Model Content

[0009] In some embodiments, the first limiting hole has a chamfer, and along the protruding direction of the chamfer, the first reinforcing rib abuts against the reinforcing flange, and / or the second reinforcing rib abuts against the reinforcing flange.

[0010] In some embodiments, the reinforcement flange further includes a third reinforcement rib, the third reinforcement rib is connected to the reinforcement flange, and an extension direction of the third reinforcement rib is parallel to an extension direction of the first reinforcement rib; or,

[0011] The third reinforcing rib is connected to the reinforcing flange, and an extending direction of the third reinforcing rib is parallel to an extending direction of the second reinforcing rib.

[0012] In some embodiments, the thickness of the first reinforcing rib is not less than 2 mm, and / or the thickness of the second reinforcing rib is not less than 2 mm.

[0013] In some embodiments, the reinforcing flange has an inner wall facing the axis of the first limiting hole, and the inner wall is parallel to the axis of the first limiting hole.

[0014] In some embodiments, the child seat includes a steel wire, the seat body is provided with the first limiting hole and the second limiting hole, the child seat has a forward use mode and a rearward use mode, in the forward use mode, the first limiting hole is suitable for passing the safety belt, in the rearward use mode, the second limiting hole is suitable for passing the safety belt, the steel wire and the seat body cooperate together to define a travel space, the travel space is suitable for the safety belt to move between the first limiting hole and the second limiting hole, so that the child seat can switch between the forward use mode and the rearward use mode.

[0015] In some embodiments, the seat body includes a seat portion and a backrest tube, the backrest tube and the seat portion are spaced apart, the steel wire is located between the seat portion and the backrest tube, and the seat portion, the backrest tube and the steel wire cooperate to define the travel space;

[0016] The seat portion has an upper surface suitable for carrying a child. The steel wire includes a bent portion that protrudes toward a side away from the upper surface. Compared to the ground, the bent portion is lower than the upper surface.

[0017] In some embodiments, the backrest tube includes a mounting column, which is used to install the steel wire. The steel wire includes a first segment and a second segment. The first segment includes the bending portion. One end of the second segment is connected to the first segment. The second segment protrudes from the first segment toward the mounting column.

[0018] According to the above embodiments, the beneficial effects of the present invention are:

[0019] The child seat provided by this utility model significantly improves the safety performance of the child seat through the cooperation of the reinforced flange, the first reinforcing rib, and the second reinforcing rib. Specifically, the seat body is provided with a first limiting hole for passing the seat belt. The seat belt is restricted in its movement within the first limiting hole. Therefore, when the vehicle stops suddenly, the child's torso deviates significantly from the seat, causing the seat belt to move significantly, and the seat belt will violently impact the edge of the first limiting hole.

[0020] A reinforcing flange is provided at the edge of the first limiting hole, and first and second reinforcing ribs are provided near the reinforcing flange to enhance the stability of the first limiting hole structure. Specifically, the first and second reinforcing ribs are both provided on the side of the first flange facing away from the first limiting hole, and both the first and second reinforcing ribs abut the side of the reinforcing flange facing away from the first limiting hole. The first and second reinforcing ribs are provided crosswise in the thickness direction.

[0021] When the vehicle stops suddenly and the seat belt collides with the edge of the first limiting hole, the part that contacts the seat belt is not only the hole wall of the first limiting hole, but also the inner wall of the first flange facing the seat belt. When the seat belt impacts the first limiting hole, the force-bearing area of ​​the structure related to the first limiting hole increases, so the impact force of the seat belt on the first limiting hole can be dispersed and absorbed, thereby reducing the possibility of damaging the first limiting hole. The first reinforcement rib and the second reinforcement rib are arranged crosswise in the thickness direction. This cross-arrangement allows the first reinforcement rib and the second reinforcement rib to support each other and disperse stress when subjected to impact force, thereby further improving the impact resistance of the first limiting hole and reducing the possibility of deformation or damage to the first limiting hole structure after impact, thereby ensuring that the child seat can provide due protection at critical moments and enhancing the safety of children riding in the vehicle.

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical utility model in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0044] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0045] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or", "and / or" or "and / or" appear in the full text, its meaning includes three parallel utility models. Taking "A and / or B" as an example, it includes A utility model, or B utility model, or a utility model that satisfies both A and B. In addition, the technical utility models between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in this field can realize it. When the combination of technical utility models is mutually contradictory or cannot be realized, it should be deemed that such a combination of technical utility models does not exist and is not within the scope of protection required by the present invention.

[0046] In the related art, when a vehicle stops suddenly, the seat belt will violently impact its limiting hole under the influence of the child's torso. This may cause the structure related to the seat belt limiting hole to deform or be damaged, making it difficult to ensure the safety of the child seat.

[0047] Reference below Figures 1 to 12 The child seat according to an embodiment of the present invention is described below. The child seat according to the present invention includes a seat body 10, which is provided with a first retaining hole 110. The edge of the first retaining hole 110 is provided with a reinforcing flange 120 protruding in a direction parallel to the axis of the first retaining hole 110. A first reinforcing rib 130 and a second reinforcing rib 140 are provided on the side of the reinforcing flange 120 facing away from the first retaining hole 110. The first and second reinforcing ribs 130 and 140 abut against the reinforcing flange 120, and the thickness directions of the first and second reinforcing ribs 130 and 140 intersect. This structure strengthens the structure of the first retaining hole 110, making it more stable. Even when the safety belt violently collides with the edge of the first retaining hole 110, the related structure of the first retaining hole 110 can maintain its original structure, thereby ensuring the safety of the child seat.

[0048] Reference Figure 1 and Figure 2In a first embodiment, a child seat includes a seat body 10 having a first retaining hole 110 formed therein. The first retaining hole 110 is used to thread a seat belt. A reinforcing flange 120 is provided at the edge of the first retaining hole 110. The reinforcing flange 120 protrudes parallel to the axis of the first retaining hole 110, enhancing the structural strength of the first retaining hole 110. The reinforcing flange 120 has an inner wall 121 oriented toward the axis of the first retaining hole 110. The inner wall 121 is parallel to the axis of the first retaining hole 110, ensuring a smooth transition between the first retaining hole wall and the reinforcing flange 120. This allows the seat belt to slide smoothly along the wall of the first retaining hole 110 or the inner wall 121 of the reinforcing flange 120. Specifically, this design ensures that when the vehicle makes an emergency stop and the seat belt collides with the edge of the first retaining hole 110, the portion of the seat belt that contacts the first retaining hole 110 is not only the wall of the first retaining hole 110, but also the inner wall 121 of the first flange facing the seat belt. When the safety belt impacts the first limiting hole 110 , the force-bearing area of ​​the structure related to the first limiting hole 110 increases, so the impact force of the safety belt on the first limiting hole 110 can be dispersed and absorbed, thereby reducing the possibility of damaging the first limiting hole 110 .

[0049] In this embodiment, in order to further improve the load-bearing capacity and impact resistance of the seat, Figure 2 A first reinforcing rib 130 and a second reinforcing rib 140 are provided on the side of the reinforcing flange 120 that faces away from the first limiting hole 110. Specifically, the first reinforcing rib 130 and the second reinforcing rib 140 are both provided on the seat body. Along the length of the first reinforcing rib 130, the first reinforcing rib 130 extends toward the side of the reinforcing flange 120 that faces away from the first limiting hole 110. Along the length of the second reinforcing rib 140, the second reinforcing rib 140 extends toward the side of the reinforcing flange 120 that faces away from the first limiting hole 110. Furthermore, the sides where the first and second reinforcing ribs 130 and 140 connect to the seat body are thickened. This arrangement ensures the structural rigidity of the first and second reinforcing ribs 130 and 140.

[0050] The first and second reinforcing ribs 130, 140 both abut against the reinforcing flange 120, and are arranged crosswise in the thickness direction. This crosswise arrangement of the first and second reinforcing ribs 130, 140 forms a three-dimensional support structure. This three-dimensional support structure allows the first and second reinforcing ribs 130, 140 to support each other and disperse stress when subjected to impact, thereby further improving the impact resistance of the first retaining hole 110 and reducing the possibility of structural deformation or damage to the first retaining hole 110 after an impact. This ensures that the child seat provides the necessary protection at critical moments, enhancing the safety of the child seat.

[0051] In particular, refer to Figure 2In this embodiment, the intersection of the first and second reinforcing ribs 130, 140 coincides with their abutment against the reinforcing flange 120, and the thickness of the first reinforcing rib 130 is perpendicular to that of the second reinforcing rib 140. This design further strengthens the mutually supporting structure of the first and second reinforcing ribs 130, 140, enabling them to jointly withstand forces from different directions, thereby improving the seat's load-bearing capacity and deformation resistance. For example, when the first retaining hole 110 is subjected to an impact force from the seat belt in a certain direction, if the force parallel to the thickness of the first reinforcing rib 130 is greater than the force parallel to the thickness of the second reinforcing rib 140, the first reinforcing rib 130 primarily bears the force. The first reinforcing rib 130 overcomes the force through its own deformation and stress distribution, thereby maintaining the structural integrity of the first retaining hole 110. The thickness of the second reinforcing rib 140 is perpendicular to that of the first reinforcing rib 130, and the first and second reinforcing ribs 130, 140, together form a three-dimensional support structure. At this time, when the first reinforcing rib 130 is subjected to a significant impact force, the second reinforcing rib 140 not only maintains its own structural stability but also provides support and, to a certain extent, shares the applied force for the first reinforcing rib 130. Therefore, the second reinforcing rib 140 and the first reinforcing rib 130 can jointly withstand the force applied by the seat belt to the first retaining hole 110, thereby achieving a more stable structure for the first retaining hole 110 and ensuring the safety of the child seat. If the force parallel to the thickness direction of the first reinforcing rib 130 is less than the force parallel to the thickness direction of the second reinforcing rib 140, the second reinforcing rib 140 primarily bears the applied force. In this case, the principle of the first and second reinforcing ribs 130, 140, working together to maintain the structural stability of the first retaining hole 110 has been previously explained and will not be repeated here.

[0052] Reference Figure 2 In this embodiment, the first limiting hole 110 also has a chamfer 111 design. Along the protruding direction of the chamfer 111, the first reinforcing rib 130 and / or the second reinforcing rib 140 abut against the reinforcing flange 120. The chamfer 111 can guide the movement direction of the seat belt and reduce its direct impact force on the first limiting hole 110. This design not only makes the connection between the first reinforcing rib, the second reinforcing rib 140 and the reinforcing flange 120 more secure, but also effectively reduces stress concentration and improves the service life of the seat. It can be understood that the first limiting hole 110 may include one chamfer 111, and the first limiting hole 110 may also include multiple chamfers 111, and the first reinforcing rib 130 and the second reinforcing rib 140 are provided at the protrusions of the multiple chamfers 111 to strengthen the structure of the first limiting hole 110.

[0053] As a preferred embodiment, the thickness of the first reinforcing rib 130 is not less than 2 mm. Specifically, the thickness of the first reinforcing rib 130 can be 2 mm, 4 mm, 6 mm, etc. The thickness of the second reinforcing rib 140 is not less than 2 mm. Specifically, the thickness of the second reinforcing rib 140 can be 2 mm, 4 mm, 6 mm, etc. By setting the minimum thickness of the first reinforcing rib 130 and the minimum thickness of the second reinforcing rib 140 to 2 mm, on the one hand, the material cost of the first reinforcing rib 130 and the second reinforcing rib 140 is reduced, and on the other hand, the first reinforcing rib 130 and the second reinforcing rib 140 are ensured to have sufficient structural strength to withstand the impact force that a child may encounter during use, and the stability of the first limiting hole 110 structure is further guaranteed.

[0054] Reference Figure 2 In the second embodiment of the present invention, to further enhance the structural strength and stability of the first limiting hole 110, the seat body 10 further includes a third reinforcing rib 150. The third reinforcing rib 150 is connected to the reinforcing flange 120 and can extend parallel to either the first reinforcing rib 130 or the second reinforcing rib 140. This design further improves support for the first limiting hole 110, thereby enhancing the structural stability of the first limiting hole 110.

[0055] The first reinforcing rib 130, the second reinforcing rib 140, and the third reinforcing rib 150 of the present invention are all used to improve the stability of the structure when the first limiting hole 110 is impacted, thereby ensuring the safety of the child seat of the present invention during use. Therefore, the first reinforcing rib 130, the second reinforcing rib 140, and the third reinforcing rib 150 only need to be able to withstand the force acting on the hole wall of the first limiting hole 110, that is, the first reinforcing rib 130, the second reinforcing rib 140, and the third reinforcing rib 150 can share the force acting on the hole wall of the first limiting hole 110.

[0056] Based on this principle and purpose, it can be understood that in some other embodiments, the thickness directions of the first reinforcing rib 130 and the second reinforcing rib 140 intersect, the first reinforcing rib 130 abuts the side of the reinforcing flange 120 facing away from the first limiting hole 110, and the second reinforcing rib 140 abuts the side of the reinforcing flange 120 facing away from the first limiting hole 110. The main body of the first reinforcing rib 130 and the main body of the second reinforcing rib 140 do not intersect, and the position where the first reinforcing rib 130 connects to the reinforcing flange 120 does not overlap with the position where the second reinforcing rib 140 connects to the reinforcing flange 120. In this arrangement, the first reinforcing rib 130 and the second reinforcing rib 140 can also form the three-dimensional support structure described above, and the first reinforcing rib 130 and the second reinforcing rib 140 work together to share the force acting on the hole wall of the first limiting hole 110.

[0057] It is understandable that in some other embodiments, the thickness directions of the first reinforcing rib 130 and the second reinforcing rib 140 intersect, the first reinforcing rib 130 abuts the first side of the reinforcing flange 120 facing away from the first limiting hole 110, and the second reinforcing rib 140 abuts the side of the reinforcing flange 120 facing away from the first limiting hole 110. The bodies of the first reinforcing rib 130 and the second reinforcing rib 140 intersect, but the bodies of the first reinforcing rib 130 and the second reinforcing rib 140 are not perpendicular to each other, and the position where the first reinforcing rib 130 connects to the reinforcing flange 120 does not overlap with the position where the second reinforcing rib 140 connects to the reinforcing flange 120. In this arrangement, the first reinforcing rib 130 and the second reinforcing rib 140 can also form the three-dimensional support structure described above, and the first reinforcing rib 130 and the second reinforcing rib 140 work together to share the force acting on the hole wall of the first limiting hole 110.

[0058] Of course, it is understandable that the third reinforcing rib 150 is not limited to being only one. If space permits, multiple third reinforcing ribs 150 can be set to cooperate with the first reinforcing rib 130 and the second reinforcing rib 140, so that the first reinforcing rib 130, the second reinforcing rib 140 and the third reinforcing rib 150 can jointly bear the force acting on the hole wall of the first limiting hole 110.

[0059] In order to maintain the stability of the structure of the first limiting hole 110, on the one hand, the supporting effect of the first limiting hole 110 is supplemented by reinforcing ribs, that is, the rigidity of the structure related to the first limiting hole 110 is increased, thereby counteracting the force acting on the hole wall of the first limiting hole 110, so that the stability of the structure related to the first limiting hole 110 is improved. On the other hand, the intensity of the force applied to the hole wall of the first limiting hole 110 can be reduced by elastic parts, that is, the stability of the structure related to the first limiting hole 110 is improved by a slow release method. Based on this, it can be understood that in some embodiments, the first limiting hole 110 has a chamfer 111, and a buffer structure, such as a buffer pad or a buffer spring, is added to the chamfer 111 of the first limiting hole 110. These buffer structures can absorb part of the impact force and reduce the direct impact of the safety belt on the limiting hole, so that the structure related to the first limiting hole 110 is not damaged.

[0060] Reference Figure 5 and Figure 6 The embodiment of the third aspect of the present invention proposes that the child seat has a steel wire 20, and the steel wire 20 has a lower bend 310, thereby increasing the travel space for the seat belt to slide at the upper end of the steel wire 20. On the one hand, it makes the seat belt slide more smoothly, improving the user experience; on the other hand, it prevents the seat belt from getting stuck in the travel space in an emergency, or avoids the high risk of disconnection after long-term use due to the large friction force on the seat belt when sliding, which will affect the safety of the child seat. Specifically, referring to Figure 3 and Figure 4The child seat includes a steel wire 20 and a seat body 10. The seat body 10 includes a seat portion 100 and a backrest tube 200. The seat body 10 is provided with a first limiting hole 110 and a second limiting hole 160. The child seat is configured to have a forward use mode and a rearward use mode. In the forward use mode, the first limiting hole 110 is used to thread the safety belt. At this time, the child sits on the seat portion 100, the backrest tube 200 is connected to the backrest to provide support for the child, and the safety belt is fixed to the child through the first limiting hole 110 to ensure his safety during driving. In the rearward use mode, the second limiting hole 160 is used to thread the safety belt. At this time, the orientation of the child sitting on the seat portion 100 is opposite to that in the forward use mode. The safety belt is fixed to the child through the second limiting hole 160 to ensure his safety during driving. The steel wire 20 and the seat body 10 cooperate to define a travel space suitable for the safety belt to move between the first limiting hole 110 and the second limiting hole 160 so as to switch the child seat between a forward use mode and a rearward use mode.

[0061] Specifically, refer to Figure 7 and Figure 8 The backrest tube 200 is spaced from the seat portion 100, and the steel wire 20 is located between the seat portion 100 and the backrest tube 200. The seat portion 100, the backrest tube 200 and the steel wire 20 cooperate to define a travel space. Figure 9 and Figure 10 The seat portion 100 has an upper surface 170 suitable for supporting a child. The steel wire 20 includes a bent portion 310 that protrudes toward a side facing away from the upper surface 170 and is lower than the ground. The lower the bent portion 310 of the steel wire 20, the lower the steel wire 20 is from the upper surface 170 of the seat portion 100. This, on the one hand, provides a larger travel space for the steel wire 20, facilitating the sliding of the safety belt within this travel space, thereby improving the user experience. On the other hand, after a child sits in the seat portion 100, the safety belt is threaded through the travel space, pressing against the child to ensure that the child can move within a certain distance from the seat backrest. The lower the pressure line is from the upper surface 170 of the seat portion 100, the tighter the safety belt is pressed down after the child sits in the child seat. Therefore, the limiting effect of the steel wire 20 on the safety belt is strengthened. When the child leans forward violently, the steel wire 20 can relieve part of the impact force of the safety belt, thereby reducing the impact force of the safety belt on the first limiting hole 110 or the second limiting hole 160, thereby further ensuring the safety of the child seat of the present invention.

[0062] In this embodiment, in order to further expand the travel space limited by the steel wire 20, refer to Figure 5 and Figure 6 as well as Figure 12The backrest tube 200 includes a mounting post 210 for mounting the steel wire 20. The steel wire 20 includes a first segment 300 and a second segment 400. The purpose of the present invention, its functional features, and advantages will be further described in conjunction with the embodiments and with reference to the accompanying drawings. The first segment 300 includes a bent portion 310. One end of the first segment 300 is mounted to the seat body 10. The second segment 400 is connected to the first segment 300 at one end. The second segment 400 protrudes from the first segment 300 toward the mounting post 210. The other end of the second segment 400 is connected to the mounting post 210. The second segment 400 has a ring structure at one end for mounting on the mounting post 210, and the mounting post 210 has an internal thread. A threaded fastener passes through the ring structure of the second segment 400 and cooperates with the mounting post 210. The end of the threaded fastener presses the steel wire 20 to achieve the connection between the steel wire 20 and the mounting post 210. By shortening the distance from the central axis of the first segment 300 to the mounting post 210, that is, shortening the distance of the second segment 400, the steel wire 20 is further away from the seat body 10, thereby increasing the travel gap defined by the steel wire 20 and allowing the seat belt to slide more smoothly within the travel gap. As a preferred embodiment, the distance L from the center of the mounting post 210 to the axis of the first segment 300 is in the range of 13 mm ≤ L ≤ 18 mm, that is, L can be 13 mm, 14 mm, 15 mm, 16 mm, 17 mm or 18 mm, etc.

[0063] Of course, it is understandable that the structures of the first reinforcing rib 130, the second reinforcing rib 140 and the third reinforcing rib 150 mentioned above are also suitable for the second limiting hole 160. Figure 11 When the child seat is in rear-facing mode, the safety belt is threaded through the second limiting hole 160. The specific design and principle have been described above and will not be repeated here. The above are only preferred embodiments of the present invention and do not limit the scope of the patent. All equivalent structural changes made based on the content of the present invention specification and drawings, or direct or indirect application in other related technical fields, are included in the scope of patent protection of the present invention.
