As shown in FIGS. 1 to 13:

in an aspect of the present disclosure, there is provided an ISOFIX installation guide device capable of guiding an installation process of an ISOFIX hook 1 and an ISOFIX connecting rod 2, comprising:

a guide housing 3, which is provided with a first opening 31 and a second opening 32 at least partially penetrating each other, wherein the first opening 31 and the second opening 32 are respectively used for guiding the ISOFIX hook 1 and the ISOFIX connecting rod 2 to be inserted into the guide housing 3; and

and a locking hook 4 movably installed inside the guide housing 3, and capable of allowing the ISOFIX connecting rod 2 to be inserted into the guide housing 3 through the second opening 32 only when the ISOFIX hook 1 is inserted into a set position in the guide housing 3 from the first opening 31.

The first opening 31 and the second opening 32 formed in the guide housing 3 partially penetrate each other, so that the ISOFIX hook 1 and the ISOFIX connecting rod 2 can be connected to each other at a region where the first opening 31 and the second opening 32 penetrate each other.

Also, since the cross-sectional area of the ISOFIX hook 1 is much smaller than the cross-sectional area of the ISOFIX connecting rod 2, and the opening areas of the first opening 31 and the second opening 32 are respectively fitted to the ISOFIX hook 1 and the ISOFIX connecting rod 2, the first opening 31 and the second opening 32 preferably only need to partially penetrate each other.

In addition, the appearance of the horn mouth that less first opening 31 and great second opening 32 formed can also be convenient it is right to guide the guide housing 3 looks both sides to arrange the seat cushion and cushion ISOFIX couple 1's encirclement to stretch into smoothly to ISOFIX couple 1's position.

While the locking hook 4 is used to ensure that the ISOFIX connecting rod 2 is correctly mounted on the ISOFIX hook 1. Specifically, when the guide housing 3 is not properly connected to the ISOFIX hook 1, the locking hook 4 blocks the second opening 32, and prevents the ISOFIX connecting rod 2 from being inserted into the guide housing 3. When the guide housing 3 is correctly connected to the ISOFIX hook 1, the locking hook 4 will allow the ISOFIX connecting rod 2 to be inserted into the guide housing 3, so that the child safety seat can be correctly mounted on the seat.

Based on the above function of the locking hook 4, when the operator finds that the ISOFIX connecting rod 2 cannot be inserted into the guide housing 3, the connection relationship between the guide housing 3 and the ISOFIX hook 1 is naturally readjusted until the locking hook 4 allows the ISOFIX connecting rod 2 to enter the second opening 32. And when the first opening 31 of the ISOFIX installation guiding device is connected with the ISOFIX hook 1, the second opening 32 can be exposed outside the gap area between the back cushion and the seat cushion of the seat, an operator can conveniently judge whether the ISOFIX hook 1 is correctly assembled with the guiding shell 3 based on the visual inspection of the position of the locking hook 4, and the ISOFIX connecting rod 2 is inserted into the guiding shell 3 when the ISOFIX installation guiding device is correctly assembled, so that the fixed installation of the child safety seat is realized.

It can be seen that, because the ISOFIX installation guide device is previously secured before the child safety seat is installed, the ISOFIX connecting rod 2 can always be connected with the ISOFIX hook 1 under the guide effect of the inner cavity of the guide housing 3, the operation step of repeatedly carrying the child safety seat to adjust the position of the ISOFIX connecting rod 2 is avoided, and the operation is greatly facilitated for an operator.

As shown in fig. 1 to 7, in order to realize stable linkage between the ISOFIX hook 1 and the locking hook 4, in some embodiments, the locking hook 4 is hinged inside the guide housing 3 and can rotate with the insertion of the ISOFIX hook 1 into the first opening 31, so as to release the locking of the insertion of the ISOFIX connecting rod 2 into the second opening 32.

In particular, as shown in fig. 3 to 5, in some embodiments the locking hook 4 comprises:

a first lug 41, projecting radially outwards with respect to the hinging axis of the locking hook 4, able to abut against the ISOFIX hook 1 during the insertion of the ISOFIX hook 1 into the guide housing 3, so as to bring about the rotation of the locking hook 4 under the push of the hook; and

a second lug 42, located on the side of the first lug 41 close to the second opening 32 and extending to the second opening 32, is movable with the rotation of the locking hook 4 from a blocking position blocking the ISOFIX connecting rod 2 from entering the second opening 32 to a release position unblocking the ISOFIX connecting rod 2.

Wherein the first lug 41 projects radially outwards with respect to the hinge axis of the latching hook 4, acting as a linkage between the insertion movement of the ISOFIX hook 1 and the rotation movement of the latching hook 4; the second lug 42 extends to the second opening 32 and serves to block or allow passage through the second opening 32.

Further, in order to better achieve the blocking effect of the second lug 42 on the second opening 32, in some embodiments, the locking hook 4 further comprises:

a stop piece 43, located at the end of the second lug 42 and perpendicular to the protruding direction of the second lug 42, for enlarging the blocking area of the second lug 42 to the second opening 32.

Further, in order to prevent the ISOFIX hook 1 from falling out after being correctly connected and matched with the ISOFIX installation guide device, in some embodiments, the locking hook 4 further includes:

a hook portion 44 located on a side of the first boss 41 close to the first opening 31 and forming an accommodation space with the first boss 41 for restricting movement of the ISOFIX hook 1 when the ISOFIX hook 1 is inserted to a set position in the guide housing 3.

Once the ISOFIX connecting rod 2 is inserted into the guide housing 3, the rotation of the second lug 42 is limited, thereby limiting the position of the locking hook 4, so that the hook always remains limited to the ISOFIX hook 1, and the limiting effect of the ISOFIX connecting rod 2 to the ISOFIX hook 1 forms a double limitation, thereby making the connection of the child safety seat more secure.

Further, in order to facilitate the insertion of the guide housing 3 to the position where the ISOFIX hook 1 is located, in some embodiments, the guide housing 3 includes:

a lower base plate 34, perpendicular to the plane of rotation of the locking catch 4; and

an upper bottom plate 33 opposite to the lower bottom plate 34 and having a cambered surface structure;

wherein the cambered surface structure enables the upper bottom plate 33 to smoothly transition from an end near the first opening 31 to an end near the second opening 32.

Further, in order to ensure that the second opening 32 is in a closed state when the guide housing 3 is not properly connected to the ISOFIX hook 1, in some embodiments, the locking hook 4 has a tendency to move to maintain the blocking position when the guide housing 3 is in a posture in which the upper base plate 33 is on top and the lower base plate 34 is on bottom.

Further, in order to achieve that the locking hook 4 has a tendency to move while remaining in the blocking position, in some embodiments the centre of gravity of the locking hook 4 is located on the side of the hinge axis which is adjacent to the second opening 32. At this point, the locking hook 4 will have a tendency to move towards the lower plate 34 under the influence of gravity, as the second lug 42 moves.

Further, as shown in fig. 4, in order to adjust the position of the second lug 42 blocking the second opening 32, in some embodiments, the guide housing 3 includes:

and a first boss 35 provided inside the upper plate 33 and close to the first opening 31, for abutting against the ISOFIX hook 1 to limit a rotation angle of the lock hook 4 when the ISOFIX hook 1 is not inserted into the guide housing 3.

Further, as shown in fig. 9, in order to make the locking hook 4 have a more reliable locking capability for the ISOFIX hook 1 and a more reliable blocking effect for the ISOFIX connecting rod 2, in some embodiments, the ISOFIX installation guide device includes two locking hooks 4, and the two locking hooks 4 are respectively hinged to two opposite inner walls of the guide housing 3 and can synchronously prevent the ISOFIX connecting rod 2 from being inserted into the second opening 32 or synchronously unlock the ISOFIX connecting rod 2 from being inserted into the second opening 32.

Further, as shown in fig. 8, in order to improve the synchronization between the two locking hooks 4, in some embodiments, the same blocking piece 43 is connected to the side of the two locking hooks 4 close to the second opening 32.

Further, as shown in fig. 10, in order to adjust the mounting height of the ISOFIX mounting guide, in some embodiments, the ISOFIX mounting guide further includes:

the wedge-shaped structure 5 is provided with a guide groove 51 on the inclined surface of the wedge-shaped structure 5;

wherein the guide groove 51 can guide the guide housing 3 to a mounting position with the ISOFIX hook 1.

The wedge-shaped structure 5 can be firstly placed between the backrest and the cushion of the seat, the mounting height of the ISOFIX installation guide device is firstly heightened aiming at the position of the ISOFIX hook 1 of a specific vehicle, and the subsequent height adjustment operation of the ISOFIX guide shell 3 is reduced.

Further, in some embodiments, the guide slot 51 is detachably connected to the lower side of the guide housing 3, so that the wedge-shaped structure 5 can be removed after the guide housing 3 and the ISOFIX hook 1 are mounted in place.

As shown in fig. 11, further, in order to conveniently connect two of the guide housings 3 to two of the ISOFIX hooks 1 at the same time, in some embodiments, the ISOFIX installation guide device further includes:

two of said wedge-shaped structures 5;
