[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] In the description of this utility model, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship when the product is in normal use.

[0024] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. The accompanying drawings of embodiments of this utility model provide a coordinate system XYZ, where the positive direction of the X-axis represents the left, the negative direction of the X-axis represents the right, the positive direction of the Y-axis represents the front, the negative direction of the Y-axis represents the rear, the positive direction of the Z-axis represents the top, and the negative direction of the Z-axis represents the bottom.

[0025] This utility model embodiment provides an ISOFIX assembly structure, as shown in Figures 1, 2, 3, and 4. It includes an ISOFIX body 1 and an ISOFIX sleeve 2. The ISOFIX sleeve 2 includes a base 21 and a stop element 22 connected to each other. The ISOFIX body 1 is slidably installed within the base 21. The stop element 22 has multiple spaced stop holes 221. The ISOFIX body 1 is movably connected to a stop tooth 11, and one of the multiple stop holes 221 engages with the stop tooth 11. The base 21 is made of plastic, and the stop element 22 is made of metal.

[0026] The base 21 is made of plastic and serves as a sliding mounting base for the ISOFIX body 1, providing a lightweight design. The stop component 22 is made of metal and has stop holes 221 for adjusting and fixing the position of the ISOFIX body 1. The stop teeth 11 cooperate with the multiple spaced stop holes 221 on the stop component 22 to adjust the different extension lengths of the ISOFIX. The base 21 occupies a much larger volume than the stop component 22. The plastic base 21 can also be used directly as an appearance component, which is aesthetically pleasing and reduces production steps and costs.

[0027] In this embodiment, the ISOFIX assembly structure separates the ISOFIX sleeve 2 into a base 21 and a stop component 22. Only the stop component 22 is made of metal, while the base 21 is made of plastic. Compared with the traditional all-metal structure, it is lighter, easier to handle and install, and also reduces production costs, making it more economical than the all-metal structure. Although the base 21 is made of plastic, the key stop component 22 is still made of metal, ensuring the strength and durability of the stop adjustment part without affecting the overall safety performance.

[0028] Optionally, as shown in Figures 3 and 4, the base 21 is provided with an upper opening 211, and the stop member 22 is connected to the upper opening 211. The upper opening 211 is located on the upper part of the base 21, and the stop member 22 is connected to the upper opening 211 to realize the installation and fixation of the stop member 22, and to form a space for the ISOFIX body 1 to slide back and forth, resulting in a compact structure.

[0029] Optionally, as shown in Figures 3 and 4, the base 21 is provided with a first fixing post 212 and a second fixing post 213 at its front and rear ends, respectively, and the stop member 22 is provided with a first mounting hole 222 and a second mounting hole 223 at its front and rear ends, respectively. The first mounting hole 222 cooperates with the first fixing post 212, and the second mounting hole 223 cooperates with the second fixing post 213.

[0030] The first fixing post 212 at the front end is inserted into the first mounting hole 222 at the front end of the stop component 22, and the second fixing post 213 at the rear end is inserted into the second mounting hole 223 at the rear end of the stop component 22. This makes the installation position of the stop component 22 more accurate, improves the installation precision, and ensures structural stability. The double fixing of the front and rear fixing posts and mounting holes increases the fixing points of the stop component 22 on the base 21, improves the overall structural stability and durability, and prevents loosening and displacement. The design of the fixing posts and mounting holes makes the installation process more intuitive and convenient, reduces installation steps and time, and improves production and assembly efficiency.

[0031] Optionally, as shown in Figures 1 to 5, the system also includes a base 3. The base 3 has a first fixing point 31 and a second fixing point 32. The first fixing post 212 passes through the first mounting hole 222 and connects to the first fixing point 31. The second fixing post 213 passes through the second mounting hole 223 and connects to the second fixing point 32. An ISOFIX assembly is installed on each of the left and right sides of the base 3, with the two ISOFIXs symmetrically arranged. The first fixing post 212 can be connected to the first fixing point 31 of the base 3 with screws, and the second fixing post 213 can be connected to the second fixing point 32 of the base 3 with screws, forming a more stable fixing structure. This significantly improves the stability and safety of the entire ISOFIX assembly structure, and the assembly process is also simpler and more efficient.

[0032] Optionally, as shown in Figures 3, 4, and 5, the top of the base 21 is provided with a positioning pin 214, and the base 3 is provided with a positioning hole that cooperates with the positioning pin 214. The design of the positioning pin 214 and the positioning hole enables the base 21 and the base 3 to be precisely aligned, ensuring accurate positioning during installation, improving the overall assembly accuracy, and allowing installers to quickly and accurately align and fix the base 21 and the base 3, simplifying the assembly process and improving production efficiency.

[0033] Optionally, as shown in Figures 3 and 4, the rear end of the base 21 is provided with a rear opening 215 for the ISOFIX body 1 to pass through; a part of the ISOFIX body 1 can extend through the rear opening 215 of the base 21 to ensure that the ISOFIX body 1 can be properly connected to the ISOFIX interface of the vehicle for fixing and installation.

[0034] Optionally, as shown in Figures 1, 3, and 4, the ISOFIX body 1 is provided with an unlock button 12, and the base 21 is provided with an elongated hole 216 that is slidably connected to the unlock button 12. The unlock button 12 passes through the elongated hole 216 and is connected to the ISOFIX body 1. The unlock button 12 is used to release or unlock the ISOFIX body 1, facilitating adjustment of the ISOFIX extension length. The sliding connection of the unlock button 12 through the elongated hole 216 makes the unlocking operation simpler, allowing easy unlocking or release of the ISOFIX body 1 without affecting other components. It also ensures the stability of the ISOFIX body 1 during operation, preventing positional shift due to improper operation.

[0035] Optionally, as shown in Figures 3 and 4, a notch 217 is provided on the side of the base 21 away from the elongated hole 216; when installed on the base 3, the unlock button 12 is on the outside and the notch 217 is on the inside, which is equivalent to the notch 217 being hidden, so it will not affect the overall appearance, and the design of the notch 217 can also reduce the overall weight.

[0036] Optionally, as shown in Figures 4 and 5, the base 21 also includes a base 3. Multiple screw posts 218 are provided on the side of the base 21 away from the elongated hole 216. The base 3 has multiple fixing holes 33 that mate with the screw posts 218. The screw posts 218 pass through the fixing holes 33 of the base 3 and are fixed to the base 3 by screws or other fasteners, ensuring a stable connection between the base 21 and the base 3. The multiple screw posts 218 mate with the fixing holes 33 on the base 3, providing multiple fixing points, further enhancing the stability of the connection between the base 21 and the base 3, and preventing loosening due to use or vibration.

[0037] Another embodiment of this utility model provides a child safety seat, including the ISOFIX assembly structure described above.

[0038] In this embodiment, the child safety seat separates the ISOFIX sleeve 2 into a base 21 and a shift mechanism 22. Only the shift mechanism 22 is made of metal, while the base 21 is made of plastic. Compared with the traditional all-metal structure, it is lighter, easier to transport and install, and also reduces production costs, making it more economical than the all-metal structure. Although the base 21 is made of plastic, the key shift mechanism 22 is still made of metal, ensuring the strength and durability of the shift adjustment part without affecting the overall safety performance.
