DETAILED DESCRIPTION

[0026] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and cannot be understood as limiting the specific scope of protection of the present application.

[0028] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0029] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0030] At present, automobile manufacturers are constantly optimizing and upgrading their cars, which has led to significant differences in the seat designs of different car models, especially the different heights of the fixed anchor points on the car seats. With the continuous improvement of the fixed anchor point design, it is difficult for existing child safety seats to perfectly adapt to the fixed anchor points of all car models. This incompatibility has brought many inconveniences to users when purchasing child safety seats.

[0031] Therefore, based on the above analysis, the present application provides an ISOFIX assembly 100 and a child safety seat having the same, so that the child safety seat can better adapt to fixed anchor points of different heights.

[0032] In some embodiments, the specific structure of the ISOFIX assembly 100 is as follows: Figure 1 As shown, the fixed end 120 can slide back and forth in the sleeve 110, so that the user can adjust the appropriate position when installing the child safety seat, and the installation is more convenient; the rotating end 130 is rotatably connected to the fixed end 120, and the height of the hook 131 in the vertical direction is adjusted by adjusting the size of the angle of the rotating end 130 in the horizontal direction. The fixed anchor point position of some vehicles may be too high or too low. By adjusting the angle of the rotating end 130 in the horizontal direction, the height of the hook 131 is adjusted, which can help users easily find the best connection position, ensure that the child safety seat can be firmly fixed to the seat of the vehicle, avoid shaking of the child safety seat during use, and reduce safety hazards during use.

[0033] In some embodiments, Figure 4 As shown, a flexible connector 140 is further provided between the fixed end 120 and the rotating end 130. Figure 5As shown, the rotating end 130 is provided with a first transmission member 133, and the fixed end 120 is provided with a second transmission member 123. The flexible connecting member 140 can be deformed, so that when the rotating end 130 rotates, the flexible connecting member 140 rotates and deforms accordingly to cooperate with the rotation of the rotating end 130 to avoid position interference; the first transmission member 133 is installed on the rotating end 130, and the second transmission member 123 is installed on the fixed end 120. One end of the flexible connecting member 140 along the axial direction of the sleeve 110 is fixedly connected to the first transmission member 133, and the other end is fixedly connected to the second transmission member 123; the flexible connecting member 140 forms a constraint between the fixed end 120 and the rotating end 130. Even if the hook 131 of the rotating end 130 becomes loose in some extreme cases, the flexible connecting member 140 can also play a certain pulling and fixing role to prevent the child safety seat from accidentally loosening and increase safety during use.

[0034] In some embodiments, Figure 2 and Figure 3 As shown, the rotating end 130 can swing upward or downward on a vertical plane, so that the height of the hook 131 in the vertical direction changes to adapt to the fixed anchor point of more models of cars.

[0035] In some embodiments, Figure 1 As shown, the fixed end 120 is provided with a flange portion 121, and the flange portion 121 blocks at least a portion of the rotating end 130 so that the end of the rotating end 130 close to the fixed end 120 can extend into the fixed end 120. On the one hand, it can prevent foreign matter from entering and causing the rotating end 130 to get stuck during rotation. On the other hand, the flange portion 121 is rotatably connected to the rotating end 130, and the flange portion 121 is provided with a first through hole for connecting the rotating end 130. A second through hole is provided at a position corresponding to the rotating end 130. The first through hole and the second through hole overlap with each other. A screw passes through the two through holes, so that the flange portion 121 is rotatably connected to the rotating end 130, so that the user can adjust the angle of the rotating end 130 in the horizontal direction, and then adjust the height of the hook 131 in the vertical direction to adapt to the fixed anchor points of more models of cars.

[0036] In some embodiments, Figure 5As shown, the two ends of the flexible connector 140 have a first protrusion 141 and a second protrusion 142, the end of the first transmission member 133 close to the flexible connector 140 is provided with a first recessed portion 1331, the first protrusion 141 is embedded in the first recessed portion 1331, and the end of the second transmission member 123 close to the flexible connector 140 is provided with a second recessed portion 1231, and the second protrusion 142 is embedded in the second recessed portion 1231, so that the flexible connector 140 is fixedly connected to the first transmission member 133 and the second transmission member 123 respectively, effectively preventing the flexible connector 140 from loosening or falling off during use, and ensuring the connection The connection is firm and the connection method is simple and intuitive. The connection can be completed by aligning the first protrusion 141 and the second protrusion 142 with the first recessed portion 1331 and the second recessed portion 1231 respectively and embedding them, which greatly improves the assembly efficiency. The connection is made by embedding, and no screws, glue or other auxiliary fixing tools are required, which reduces the assembly cost and complexity and facilitates disassembly and replacement. The protrusion fits tightly with the recessed portion, so that the friction and stress distribution of the flexible connector 140 during use is more uniform, which reduces the wear at both ends of the flexible connector 140 and increases the service life of the flexible connector 140.

[0037] In some embodiments, the flexible connector 140 is a steel rope, which has extremely high tensile strength, and can ensure that the flexible connector 140 is not easy to break during the use of the child safety seat, thereby increasing safety during use. Moreover, the steel wire can still maintain good performance under repeated stress conditions, thereby increasing the service life of the child safety seat. At the same time, the steel wire can deform to adapt to the rotation of the rotating end 130, avoiding position interference, and making the rotation of the rotating end 130 more flexible and smooth.

[0038] In some embodiments, the first transmission member 133 has a first extension end 1332, and the first extension end 1332 is disposed on a side of the first transmission member 133 away from the flexible connector 140, and the hook 131 has a second extension end 1311. Figure 7As shown, the first extension end 1332 and the second extension end 1311 abut against each other to limit the movement of the hook 131; the first extension end 1332 of the first transmission member 133 and the second extension end 1311 of the hook 131 abut against each other, so that the rotation of the hook 131 can be effectively limited, thereby enhancing the stability of the ISOFIX component 100 and preventing the hook 131 from rotating or shaking unnecessarily due to external force during use; the mutual abutment between the first extension end 1332 and the second extension end 1311 can disperse stress, reduce local stress concentration of the hook 131 when it is impacted, enhance the impact resistance of the ISOFIX component 100, and limit the hook 131 without adding additional fixing devices, thereby saving space and making the internal structure of the ISOFIX component 100 more compact, and can also reduce the direct friction between the hook 131 and the first transmission member 133, thereby reducing wear and extending the service life of the ISOFIX component 100.

[0039] In some embodiments, Figure 6 As shown, the fixed end 120 has a guide groove 122, and the extension direction of the guide groove 122 is consistent with the axial direction of the sleeve 110. The second transmission member 123 reciprocates along the guide groove 122, and the extension direction of the guide groove 122 is consistent with the axial direction of the sleeve 110, ensuring that the second transmission member 123 can only reciprocate along a predetermined direction, that is, the axial direction of the sleeve 110, avoiding the second transmission member 123 from deflecting or shaking in other directions, thereby improving the stability and reliability of the ISOFIX assembly 100.

[0040] In some embodiments, the second transmission member 123 has a fixing pin, which is embedded in the guide groove 122 to fix the second transmission member 123 on the guide groove 122. The fixing pin drives the second transmission member 123 to reciprocate along the direction in which the guide groove 122 extends, thereby simplifying the connection method between the second transmission member 123 and the guide groove 122 and reducing the difficulty of assembly. The connection is performed through a fixing pin with a simple structure, thereby reducing the production cost of the ISOFIX assembly 100.

[0041] In some embodiments, Figure 3 As shown, the ISOFIX assembly 100 further includes: an unlocking button 150, which is adapted to drive the flexible connector 140 to move from the first working position to the second working position, so that the first extension end 1332 and the second extension end 1311 are separated from each other.

[0042] Specifically, when the hook 131 is fixedly connected to the fixed anchor point, the first extension end 1332 of the first transmission member 133 and the second extension end 1311 of the hook 131 abut against each other. At this time, the flexible connecting member 140 is in the first working position, and the fixing pin of the second transmission member 123 is at the end of the guide groove 122 close to the first transmission member 133. The hook 131 cannot rotate, which can prevent the hook 131 from being separated from the fixed anchor point. When the child safety seat needs to be removed, the user presses the unlocking button 150, which drives the fixing pin to move from the end of the guide groove 122 close to the first transmission member 133 to the end away from the first transmission member 133, so that the first extension end 1332 and the second extension end 1311 are separated from each other. The first extension end 1332 no longer restricts the rotation of the hook 131, and the hook 131 swings, so that the fixed anchor point can be separated from the hook 131, thereby separating the hook 131 from the fixed anchor point, and removing the child safety seat. The disassembly method is simpler, convenient for users to operate, and more convenient during use.

[0043] In some embodiments, the guide groove 122 can limit the sliding travel of the fixing pin, the unlocking button 150 and the flexible connector 140, so that the fixing pin can slide between the first working position and the second working position, so that the hook 131 can switch back and forth between locking and unlocking.

[0044] In some embodiments, Figure 6 As shown, the sleeve 110 is provided with a slot 111, and the shift member 124 is rotatably installed in the fixed end 120. The shift member 124 has a snap-in portion, which can be embedded in the slot 111, thereby limiting the reciprocating sliding of the fixed end 120 in the sleeve 110, wherein the shift member 124 is also provided with a limit compression spring, which can abut against the shift member 124, thereby limiting the rotation of the shift member 124 to lock the fixed end 120; when disassembling the child safety seat, the user slides the unlocking button 150, and the first transmission member 133 pushes the shift member 124 to rotate, so that the snap-in portion disengages from the slot 111 to unlock the fixed end 120, so that the fixed end 120 resumes sliding.

[0045] The present application also provides a child safety seat, which includes the above-mentioned ISOFIX assembly 100. Therefore, the child safety seat has all the beneficial effects of any technical solution of the above-mentioned ISOFIX assembly 100, which will not be repeated here.

Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought.
