Description

Technical Field

[0001] This utility model relates to the field of automotive safety products technology, and more specifically, to a reinforced connection structure and a child safety seat. Background Technology

[0002] Child safety seats include a base assembly, a rotating disc assembly, and a backrest. The backrest is slidably mounted on the rotating disc assembly to allow for tilt angle adjustment. The rotating disc assembly is rotatably connected to the base assembly, and the backrest can rotate synchronously with the rotating disc assembly. Currently, the connection structure between the rotating disc assembly and the base assembly is concentrated in the middle and has relatively low strength. When the vehicle brakes suddenly, the backrest will cause the rotating disc assembly to generate a forward tilting force, resulting in low stability on the side of the rotating disc assembly facing the rear of the base assembly, making it prone to tilting up and affecting the riding experience and comfort. Utility Model Content

[0003] To address at least one of the aforementioned problems, this utility model first provides a reinforced connection structure, including a base module and a rotating module. The base module is adapted to be connected to a car seat, and the rotating module is located on top of the base module and rotatably connected to it. A turntable fixing frame is fixedly provided on the base module, and a reinforcing plate is fixedly provided on the rotating module. The turntable fixing frame is located above the reinforcing plate and is adapted to prevent the reinforcing plate from flipping relative to the base module.

[0004] Optionally, the rotating module is located on the front side of the turntable fixing frame, and the front and rear sides of the rotating module are provided with reinforcing plates suitable for cooperating with the turntable fixing frame.

[0005] Optionally, the base module includes a base cover and an ISOFIX assembly. The ISOFIX assembly is installed inside the base cover. One side of the turntable mounting bracket is fixedly connected to the ISOFIX assembly, and the other side is fixedly connected to the base cover.

[0006] Optionally, a connector is fixedly mounted on the ISOFIX assembly, and the turntable mounting bracket is fixedly connected to the connector.

[0007] Optionally, the turntable fixing frame includes a fixed base plate, an extension plate, and a blocking plate connected in sequence. The fixed base plate and the blocking plate are located at the upper and lower ends of the extension plate, respectively. The fixed base plate is fixedly connected to the base module, and the reinforcing plate is adapted to be located directly below the blocking plate.

[0008] Optionally, the extension plate has a clearance notch on the side near the rotating module, and the reinforcing plate is adapted to pass through the clearance notch and be located below the blocking plate.

[0009] Optionally, the rotating module includes a rotating disk and a slide rail fixing plate. The rotating disk is rotatably connected to the base module. The slide rail fixing plate is installed on the top of the rotating disk and rotates synchronously with the rotating disk. The slide rail fixing plate is adapted to be connected to the chair back. The reinforcing plate is fixedly connected to the slide rail fixing plate.

[0010] Optionally, the reinforcing plate includes a fixed mounting portion and a reinforcing mating portion. The fixed mounting portion is fixedly connected to the slide rail fixing plate, and the reinforcing mating portion is adapted to be located below the blocking plate. The width of the reinforcing mating portion is greater than the width of the fixed mounting portion.

[0011] Optionally, the end of the reinforcing mating part away from the fixed mounting part is bent upward with an upper folding plate, and the front side of the blocking plate is bent downward with a lower folding plate. The upper folding plate is adapted to be located behind the lower folding plate and hooked to the lower folding plate.

[0012] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0013] 1. Based on the original connection between the base module and the rotating module, an additional load-bearing structure turntable fixing frame and reinforcing plate are added. When the vehicle brakes suddenly, the turntable fixing frame can rotate the reinforcing plate to block the movement, while bearing part of the rotation force and dispersing the rotation force to avoid concentrated force in one place. This enhances the stability of the connection between the base module and the rotating module, improves the strength, makes the rotating module less likely to rotate and tilt, and improves the comfort of the ride.

[0014] 2. Typically, ISOFIX components are made of metal. The turntable bracket is fixedly connected to the ISOFIX component via connectors. The ISOFIX component can be fixedly connected to the car seat and has high stability after connection. Therefore, the connection between the turntable bracket and the ISOFIX component enhances the stability of the connection.

[0015] 3. The reinforcing part of the reinforcing plate mates with the turntable fixing frame. Therefore, the width of the reinforcing part is set to be greater than the width of the fixing part, which can increase the mating area with the turntable fixing frame and further improve the stability when the turntable fixing frame and the reinforcing plate are mated.

[0016] 4. The upper and lower bending plates are hooked together to form a snap-fit ​​structure, which can further improve the strength of the turntable fixing frame and the reinforcing plate after they are combined.

[0017] 5. When children of different ages ride in the chair, the backrest either faces forward or backward. Therefore, reinforcing plates are set on both the front and rear sides of the rotating module. Depending on the orientation of the backrest, the corresponding reinforcing plate cooperates with the turntable fixing frame, so that it has high connection strength and stability in both different usage scenarios.

[0018] In addition, this utility model provides a child safety seat, including the reinforced connection structure described above.

[0019] Compared to existing technologies, the child safety seat described in this utility model has the same advantages as the aforementioned reinforced connection structure, which will not be repeated here. Attached Figure Description

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the following description is provided in conjunction with the appendix. Figure 1-8 This application will be described in further detail.

[0030] The accompanying drawings of this utility model embodiment provide a coordinate system XYZ, where the positive direction of the X-axis represents the right, the negative direction of the X-axis represents the left, the positive direction of the Y-axis represents the front, the negative direction of the Y-axis represents the back, the positive direction of the Z-axis represents the top, and the negative direction of the Z-axis represents the bottom.

[0031] In a first aspect, this utility model embodiment provides a reinforced connection structure, referring to... Figures 1 to 3 The reinforced connection structure includes a base module 1 and a rotating module 2. The base module 1 is suitable for fixed connection with a car seat. The rotating module 2 is located on top of the base module 1 and is rotatably connected to the base module 1. A seat back for a child to sit on is connected to the rotating module 2, and the seat back rotates synchronously with the rotating module 2. A turntable fixing frame 11 is fixedly provided on the base module 1, and a reinforcing plate 21 is fixedly provided on the rotating module 2. The turntable fixing frame 11 is located above the reinforcing plate 21. When the vehicle brakes suddenly, the turntable fixing frame 11 can prevent the reinforcing plate 21 from flipping relative to the base module 1, and at the same time bear part of the flipping force, dispersing the flipping force and avoiding concentrated force in one place. This enhances the stability of the connection between the base module 1 and the rotating module 2 and improves the strength of the connection between the base module 1 and the rotating module 2.

[0032] The base module 1 includes a lower base cover 12, ISOFIX components 13, and an upper base cover 14. Two sets of ISOFIX components 13 are provided, both located symmetrically within the lower base cover 12. Each ISOFIX component 13 includes a retaining sleeve and a telescopic rod, both made of metal. The retaining sleeve is fixedly installed inside the lower base cover 12, and the telescopic rod is slidably inserted into the retaining sleeve, adapted to extend from the rear of the lower base cover 12 and connect securely to the ISOFIX interface on the car seat. The upper base cover 14 is located above the lower base cover 12 and connected to it.

[0033] Reference Figures 1 to 3 In this embodiment, two turntable fixing brackets 11 are preferably provided, and the two turntable fixing brackets 11 are symmetrically arranged along the left and right direction of the base module 1. Both turntable fixing brackets 11 are located behind the rotating module 2, so that they can directly act on the rear of the rotating module 2. The two turntable fixing brackets 11 are fixedly connected to two fixing sleeves respectively. After the turntable fixing brackets 11 are fixedly connected to the metal fixing sleeves, the strength and stability of the turntable fixing brackets 11 after installation can be improved. The two turntable fixing brackets 11 have the same structure and the same connection structure with the corresponding fixing sleeves. The following description uses the structure of one turntable fixing bracket 11 and its connection structure with the fixing sleeve as an example.

[0034] Each fixed sleeve has a connector 15 bolted to its outer wall. In another embodiment, the connector 15 can be welded to the fixed sleeve. The connector 15 is a plate similar to the shape of a "7". The turntable fixing frame 11 is hooked to the connector 15 and fixed to it with bolts. The turntable fixing frame 11, the reinforcing plate 21, and the connector 15 are all made of metal, which improves the strength of the turntable fixing frame 11 and the connector 15 after connection; it also improves the strength of the turntable fixing frame 11 and the reinforcing plate 21 when they are in contact.

[0035] Reference Figures 2 to 4 The turntable fixing frame 11 includes a fixed base plate 111, an extension plate 112, and a blocking plate 113 connected in sequence. The fixed base plate 111, extension plate 112, and blocking plate 113 are formed by bending the same plate, thereby ensuring the strength of the turntable fixing frame 11 itself. The fixed base plate 111 and the blocking plate 113 are located at the upper and lower ends of the extension plate 112, respectively, and on the left and right sides of the extension plate 112, respectively. The blocking plate 113 is located on the side of the extension plate 112 closest to another turntable fixing frame 11. The fixed base plate 111 is located below the top plate of the connector 15 and hooked to the connector 15, and fixed by bolts. The reinforcing plate 21 is adapted to be located directly below the blocking plate 113, so that the blocking plate 113 blocks the reinforcing plate 21 from moving upward or flipping, thereby strengthening the connection strength between the base module 1 and the rotating module 2. In another embodiment, the turntable fixing frame 11 can be just a single plate, with the reinforcing plate 21 located below the turntable fixing frame 11.

[0036] Reference Figures 2 to 6 The baffle plate 113 has a connecting side plate 114 formed by bending downwards on the side near the other turntable fixing frame 11. The connecting side plate 114 is fixedly connected to the lower cover 12 of the base by bolts, thus giving the turntable fixing frame 11 two fixing points and improving the stability of the turntable fixing frame 11 after installation. The front side of the baffle plate 113 has a downward bending plate 115, which can form a structure that hooks and connects with the reinforcing plate 21 in the front and back directions, further strengthening the locking structure for the front and back movement of the rotating module 2, and further limiting the front and back movement of the rotating module 2.

[0037] The top of the base cover 14 has a through hole that extends through the base cover 14. The rotating module 2 includes a rotating disk 22 and a slide rail fixing plate 23. The rotating disk 22 is located inside the through hole and is rotatably connected to the bottom cover 12 of the base, allowing the rotating disk 22 to rotate within the through hole. The slide rail fixing plate 23 is fixedly installed on the top of the rotating disk 22, and the chair back is connected to the slide rail fixing plate 23. Two slide rail fixing plates 23 are symmetrically spaced along the left-right direction on the rotating disk 22, and the slide rail fixing plates 23 are made of metal.

[0038] Reference Figures 3 to 7 The reinforcing plate 21 is fixedly connected to the slide rail fixing plate 23 by bolts. Both the reinforcing plate and the slide rail fixing plate 23 are made of metal, ensuring the strength of the connection. Reinforcing plates 21 are installed on both slide rail fixing plates 23, and each reinforcing plate 21 cooperates with one of the two turntable fixing frames 11. This further disperses the force, resulting in more even stress distribution and improved strength. Furthermore, reinforcing plates 21 are installed at both the front and rear ends of the two slide rail fixing plates 23. When children of the same age are riding, the seat back faces either forward or backward. Therefore, regardless of whether the seat back faces forward or backward, the reinforcing plate 21 on the same side of both slide rail fixing plates 23 can cooperate with the corresponding turntable fixing frame 11, providing high connection strength and stability in both different usage scenarios.

[0039] Reference Figures 3 to 8 The reinforcing plate 21 includes a fixed mounting part 211 and a reinforcing mating part 212. The fixed mounting part 211 is connected to the slide rail fixing plate 23 by bolts. The reinforcing mating part 212 protrudes from the slide rail fixing plate 23 and is cantilevered. The reinforcing mating part 212 is adapted to be located below the blocking plate 113. The width (length in the left-right direction) of the reinforcing mating part 212 is greater than the width (length in the left-right direction) of the fixed mounting part 211, so that the mating area between the reinforcing mating part 212 and the blocking plate 113 is larger, thereby improving the strength and stability of the turntable fixing frame 11 and the reinforcing plate 21 when they are mated.

[0040] The end of the reinforcing mating part 212 away from the fixed mounting part 211 is bent upwards with an upper folding plate 213. The upper folding plate 213 is adapted to rotate with the turntable 22 to be below the blocking plate 113 and located directly behind the lower folding plate 115. Thus, the upper folding plate 213 and the lower folding plate 115 are hooked together like two hooks, further improving the strength of the turntable fixing frame 11 and the reinforcing plate 21 after they are mated.

[0041] The extension plate 112 has a clearance notch 116 on the side near the rotating disk 22 (i.e. the front side of the extension plate 112). When the rotating disk 22 drives the reinforcing plate 21 to rotate, the reinforcing plate 21 can rotate through the clearance notch 116 to the area directly below the blocking plate 113, or rotate out from the area directly below the blocking plate 113 through the clearance notch 116.

[0042] The implementation principle of the reinforced connection structure in this application embodiment is as follows: the turntable fixing frame 11, the reinforcing plate 21, the connector 15, and the slide rail fixing plate 23 are all made of metal. The ISOFIX assembly 13 is also typically made of metal. The turntable fixing frame 11 is fixedly connected to the ISOFIX assembly 13 via the connector 15. The ISOFIX assembly 13 can be fixedly connected to the car seat, and the connection provides high stability. Therefore, the connection between the turntable fixing frame 11 and the ISOFIX assembly 13 results in high strength. Similarly, the strength is also increased after the reinforcing plate 21 is connected to the slide rail fixing plate 23.

[0043] Based on the original connection between base module 1 and rotating module 2, an additional load-bearing structure, turntable fixing frame 11 and reinforcing plate 21, are added. During sudden braking, the turntable fixing frame 11 can rotate with the reinforcing plate 21 to provide resistance, while also bearing part of the rotational force, dispersing the force and preventing concentrated stress in any one area. This enhances the stability and strength of the connection between base module 1 and rotating module 2. The upper bent plate 213 and lower bent plate 115 are hooked together to form a snap-fit ​​structure, further improving the strength of the turntable fixing frame 11 and reinforcing plate 21 when they are in contact.

[0044] Secondly, another embodiment of the present invention provides a child safety seat, including the reinforced connection structure described in the first aspect.
