[0022] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0023] The utility model provides an ISOFIX integrated sleeve structure, combined with Figure 1 , Figure 2 , Figure 3 As shown, it includes a sleeve body 1 and a fixing ear 2, the sleeve body 1 and the fixing ear 2 are both made of metal, and the fixing ear 2 is integrally formed with the sleeve body 1.

[0024] The sleeve body 1 is made of metal material, which has high strength and durability and can withstand large external forces; the fixing ear 2 is also made of metal material and is integrally formed with the sleeve body 1 through sheet metal processing; during the manufacturing process, the sleeve body 1 and the fixing ear 2 are integrally formed by a molding process such as casting, forging or stamping, so that the two become a whole in terms of physical structure; after molding, the edges of the sleeve body 1 that contact each other can be connected by welding. Figure 3 As shown, the maximum force value of the tested straight pull force can reach 10.1KN, while the original casing can only reach about 9KN, and the strength is significantly increased.

[0025] The ISOFIX integrated sleeve structure in this embodiment does not require additional welding steps because the sleeve body 1 and the fixing ear 2 are integrally formed, which simplifies the manufacturing process and improves production efficiency. The one-piece structure eliminates seams or welding points between the sleeve body 1 and the fixing ear 2, reducing potential structural weaknesses, thereby improving the overall connection strength and durability, and also improving safety.

[0026] Optionally, the fixing ear 2 and the sleeve body 1 are integrally formed by a sheet metal process; using the sheet metal process, through stamping, bending, cutting and other process steps, the metal material is processed into a structure integrating the sleeve body 1 and the fixing ear 2. This process can ensure the accuracy and consistency of the structure without additional welding or seams, thereby improving the strength and reliability of the overall structure and improving the overall strength.

[0027] Optionally, combined Figure 1 , Figure 2 As shown, the fixing ear 2 includes a first fixing plate 21 and a second fixing plate 22. Before molding, the first fixing plate 21 and the second fixing plate 22 are respectively located at the upper and lower sides of the sleeve body 1. After molding, the first fixing plate 21 and the second fixing plate 22 are stacked on each other.

[0028] Before molding, the first fixing plate 21 is located on the upper side of the sleeve body 1, and the second fixing plate 22 is located on the lower side of the sleeve body 1, and they are two separate sheet structures; after integral molding through sheet metal processing, the first fixing plate 21 and the second fixing plate 22 are stacked on each other to form an integral fixing ear 2 structure. This stacking arrangement increases the thickness and strength of the fixing ear 2, and further improves the firmness and reliability of the overall connection.

[0029] Optionally, combined Figure 1 , Figure 2 As shown, after molding, the first fixing plate 21 and the second fixing plate 22 are overlapped with each other; the first fixing plate 21 and the second fixing plate 22 have the same appearance, size and shape, and after integral molding, the first fixing plate 21 and the second fixing plate 22 are overlapped with each other, which enhances the connection strength of the overall structure, and the overall appearance after molding is neater and more beautiful; the overlapping structure makes the fixing ear 2 more sturdy and durable, can maintain stable performance for a long time, and prolongs the service life of the product.

[0030] Optionally, combined Figure 1 , Figure 2 As shown, the first fixing plate 21 is provided with a first mounting hole 211, and the second fixing plate 22 is provided with a second mounting hole 221. After molding, the first mounting hole 211 and the second mounting hole 221 are correspondingly arranged. Before molding, the first mounting hole 211 on the first fixing plate 21 and the second mounting hole 221 on the second fixing plate 22 are already designed. After integral molding, the first mounting hole 211 and the second mounting hole 221 are correspondingly arranged, that is, they are located at the overlapping part of the fixing ear 2 and are in the same position. The corresponding arrangement makes the installation process more convenient and can be accurately installed on the vehicle base.

[0031] Optionally, combined Figure 1 As shown, the first mounting hole 211 is a waist-shaped hole, and the second mounting hole 221 is a circular hole.

[0032] Among them, the waist-shaped hole has a certain fault tolerance, making the installation process more flexible and simple, reducing the strict requirements for installation accuracy, and helping to reduce the cost and complexity of the manufacturing process; at the same time, the circular hole can ensure a firm connection between the fixing ear 2 and the base. The design of the circular hole needs to ensure that the hole on the installation object is completely matched with the diameter of the circular hole, so as to obtain the best connection effect and ensure the stability and safety of the entire system. The first installation hole 211 is a waist-shaped hole, and the second installation hole 221 is a circular hole. The combined design of the waist-shaped hole and the circular hole achieves a good balance in the ISOFIX integrated sleeve structure, giving full play to their respective advantages, which not only improves the flexibility and simplicity of installation, but also ensures the firmness of the connection, while reducing the manufacturing cost and complexity.

Before molding, the connecting piece 3 has been designed and cut, and the third mounting hole 31 has also been designed. After molding, the third mounting hole 31 is completely retained on the connecting piece 3; the tail of the sleeve body 1 refers to the end away from the fixing ear 2; the design of the connecting piece 3 enables the tail of the sleeve body 1 to form a protruding structure in the length direction, which can be more firmly connected to the base, thereby improving the stability and reliability of the overall connection.

[0034] Optionally, combined Figure 1 , Figure 2 As shown, after forming, the connecting piece 3 is bent to form a connecting surface 32 and a bending surface 33, wherein the connecting surface 32 is located on the top surface, the bending surface 33 is located on the side surface, and the third mounting hole 31 is provided on the connecting surface 32. After forming, the connecting piece 3 presents a bent shape, and is formed with two parts, the connecting surface 32 and the bending surface 33. The connecting surface 32 is located on the top surface of the connecting piece 3 and is the main contact surface connected with the base, and the bending surface 33 is located on the side surface of the connecting piece 3. A bend is formed between the connecting surface 32 and the bending surface 33, so that the connecting piece 3 can better adapt to the shape of the seat; after the connecting surface 32 is formed, the third mounting hole 31 is completely retained on the connecting surface 32 for installing and connecting the seat; the bending design of the connecting piece 3 and the position of the third mounting hole 31 make the ISOFIX integrated sleeve structure more universal and applicable, and can be more conveniently used with different types of seats.

[0035] Optionally, combined Figure 1 , Figure 2 As shown, the sleeve body 1 is further provided with a gear hole 11. After molding, the gear hole 11 is located on the top surface, and the gear hole 11 and the third mounting hole 31 are located on the same straight line; the gear hole 11 is used to fix the length of the ISOFIX extending relative to the base, and the position of the gear hole 11 is on the same straight line as the third mounting hole 31, so that the connection between the connecting piece 3 and the base is more stable, thereby improving the stability and safety of the overall structure.
