[0049] The technical solutions in the embodiments will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] In the description of the present invention, it should be understood that the terms "center", "lateral", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the scope of protection of the present invention.

[0051] like Figure 1 and Figure 2 As shown, in an illustrative embodiment of the ISOFIX connection device for a child safety seat provided by the present invention, the ISOFIX connection device includes a pair of ISOFIX connectors 10, which are respectively connected to a base 100 of the child safety seat and can be folded toward each other for storage.

[0052] Optionally, one of the pair of ISOFIX connectors 10 is connected to the left side of the base 100, and the other of the pair of ISOFIX connectors 10 is connected to the right side of the base 100. The two ISOFIX connectors 10 can be folded inward relative to each other to achieve storage. When folded, the two ISOFIX connectors 10 and the base 100 are always in the same plane.

[0053] In the above exemplary embodiment, a pair of ISOFIX connectors 10 can be folded toward each other, so that the ISOFIX connectors 10 can be stored by folding when not in use, which is convenient for transportation; and the pair of ISOFIX connectors 10 are folded toward each other in a direction close to each other, which is not only convenient and labor-saving to operate, but also safe.

[0054] Specifically, in the related art, the ISOFIX connector and the connecting rod connected to the ISOFIX connector are flipped backward 180° as a whole, so that the ISOFIX connector and the connecting rod are flipped as a whole to under the base of the child safety seat. Although this can also achieve the storage of the ISOFIX connector, this method requires the entire child safety seat to be completely lifted up when flipping, and sufficient flipping space must be reserved for the ISOFIX connector and the connecting rod as a whole, which is time-consuming and labor-intensive. In the embodiment of the present invention, the ISOFIX connector can be folded inward to achieve storage. The operation method is more in line with people's operating habits, and there is no need to completely lift the entire child safety seat, saving time and effort. In addition, when the child safety seat is hit in the forward direction, the child occupant will be tied up by the restraint system and the seat back will flip forward. At this time, all the forces that limit the seat flipping will fall on the connecting rod connected to the IOSFIX joint. If the storage method in the above-mentioned related technology is adopted, the connecting rod is rotatable in the force direction, which will increase the risk of the seat flipping. Therefore, the safety of this storage method is poor. In the embodiment of the present invention, even if the forces that limit the seat flipping all fall on the connecting rod connected to the IOSFIX joint, the risk of the seat flipping will not increase. The connecting rod can be rigidly connected in the forward flipping direction of the seat, which has good safety.

[0055] like Figure 3 As shown, the child safety seat ISOFIX connection device further includes a rotation mechanism 30, which is used to enable the ISOFIX connector 10 to be rotatably arranged relative to the base 100. By rotating the ISOFIX connector 10 relative to the base 100, the ISOFIX connector 10 can be folded.

[0056] There are many options for the specific structural form of the rotating mechanism 30 , as long as the ISOFIX connector 10 can be rotatably arranged relative to the base 100 .

[0057] Optionally, the child safety seat ISOFIX connection device further includes a first rod 20, one end of which is connected to the ISOFIX connector 10, and the other end of the first rod 20 is rotatably arranged relative to the base 100 through a rotating mechanism 30. By providing the first rod 20, firstly, it is convenient to connect with the rotating mechanism 30, and secondly, it is possible to reserve space for providing an unlocking mechanism 70 on the ISOFIX connector 10, and the unlocking mechanism 70 is used to achieve locking or unlocking between the ISOFIX connector 10 and the interface on the rear seat of the car.

[0058] The specific structure of the unlocking mechanism 70 is not limited herein, as long as it can achieve locking or unlocking between the ISOFIX connector 10 and the interface on the rear seat of the vehicle.

[0059] In an optional embodiment, the rotating mechanism 30 includes a sleeve 31 and a rivet 32, the sleeve 31 is sleeved on the rivet 32, and a rotating hinge is formed between the first rod 20 and the base 100, so that the first rod 20 can be rotatably arranged relative to the base 100. Figure 4 and Figure 5 As shown, when the first rod 20 rotates relative to the base 100 , the ISOFIX connector 10 can be driven to rotate relative to the base 100 , thereby achieving folding of the ISOFIX connector 10 .

[0060] Optionally, the rotation angle of the pair of ISOFIX connectors 10 when folded toward each other is greater than 0° and less than or equal to 180°. Preferably, the rotation angle is 90°.

[0061] Optionally, the child safety seat ISOFIX connection device further includes a safety restriction structure, which is used to restrict the rotation of the ISOFIX connector 10, and the ISOFIX connector 10 can only rotate relative to the base 100 after the restriction of the safety restriction structure is released. By providing the safety restriction structure, the ISOFIX connector 10 can be prevented from accidentally rotating, causing unnecessary folding and affecting the stability of the child safety seat.

[0062] Optionally, the safety restriction structure includes a damping point arranged on the rotating mechanism 30 or the ISOFIX connector 10, and the ISOFIX connector 10 rotates relative to the base 100 after overcoming the resistance of the damping point. This restriction structure is simple, reliable and safe.

[0063] In addition, a damping point may also be provided at the connection between the ISOFIX connector 10 and the base 100. By providing the damping point, when the ISOFIX connector 10 is connected to the car seat, it is possible to effectively prevent the ISOFIX connector 10 from being separated from the base 100 due to pulling, which is conducive to improving the reliability of the connection.

[0064] like Figure 6 and Figure 7 As shown, the child safety seat ISOFIX connection device further includes a second rod 40, which is connected between the ISOFIX connector 10 and the base 100 and can be extended or retracted relative to the base 100. This arrangement can adjust the distance between the ISOFIX connector 10 and the base 100 as needed to adapt to the connection between the rear seats of cars of different types and sizes and the child safety seats, thereby increasing the scope of application.

[0065] Optionally, the child safety seat ISOFIX connection device further includes an adjustment mechanism 50, which is used to adjust the extension length of the second rod 40 relative to the base 100. By providing the adjustment mechanism 50, it is more convenient to adjust the extension length of the second rod 40 relative to the base 100. When the anchor point depth on the rear seat of the car is large, the extension length of the second rod 40 can be increased by the adjustment mechanism 50; and when the anchor point depth on the rear seat of the car is small, the second rod 40 can be retracted by the adjustment mechanism 50 to shorten the total length of the ISOFIX connection device.

[0066] There are many options for the specific structural form of the adjustment mechanism, as long as the adjustment purpose can be achieved.

[0067] Optionally, the adjustment mechanism 50 includes an adjustment button 52, which is used to release the lock when operated so that the second rod 40 can be extended or retracted relative to the base 100; the adjustment button 52 is also used to restore the locking effect after resetting so that the second rod 40 and the base 100 are relatively fixed.

[0068] Furthermore, the child safety seat ISOFIX connection device further includes a bracket 60, and the bracket 60 is connected to the base 100. After the bracket 60 is provided, the above-mentioned connection between the second rod 40 and the base 100 can be understood as the connection between the second rod 40 and the bracket 60.

[0069] The adjustment mechanism 50 further includes an adjustment base 53, which is sleeved on the bracket 60 and is rotatably connected to the middle of the adjustment button 52. The first end of the adjustment button 52 is provided with a lock rod that can be inserted into the lock hole 42 provided on the second rod 40, and the second end of the adjustment button 52 can be pressed. The adjustment base 53 and the adjustment button 52 form a lever structure, and the connection point between the adjustment base 53 and the adjustment button 52 is a fulcrum. When the second end of the adjustment button 52 is pressed, the adjustment button 52 rotates relative to the adjustment base 53, and the first end of the adjustment button 52 tilts upward, driving the lock rod to move upward and leave the connection position between the second rod 40 and the base 100, so that the second rod 40 and the base 100 are disconnected; and after the second end of the adjustment button 52 is reset, the first end of the adjustment button 52 is also reset, driving the lock rod to reset and reconnect the second rod 40 and the base 100.

[0070] Optionally, the second rod 40 is provided with a plurality of locking holes 42 arranged along the length direction, the bracket 60 is provided with a mounting hole 61, the bracket 60 is a hollow structure, the second rod 40 is inserted into the bracket 60, and when the locking rod is aligned with one of the locking holes 42, the locking rod is inserted into the locking hole 42 to achieve the connection between the second rod 40 and the bracket 60. When the locking rod is aligned with the other locking hole 42 and the locking rod is inserted into the locking hole 42, the extension length of the second rod 40 relative to the bracket 60 is changed, and the distance of the ISOFIX connector 10 relative to the base 100 is adjusted.

[0071] The above only provides a specific structural form that can achieve the adjustable relative position between the second rod 40 and the bracket 60. In other embodiments, other structural forms can also be used, which will not be listed here one by one.

[0072] Optionally, the adjustment mechanism also includes a limit member 51, and a long groove 41 is provided on the opposite side of the second rod 40 where the lock hole 42 is set. The limit member 51 passes through the mounting hole of the adjustment base 53 and the bracket 60 and is inserted into the long groove 41 to connect the bracket 60 and the second rod 40, and enable the second rod 40 to slide relative to the bracket 60, while preventing the second rod 40 from detaching from the bracket 60 when it moves to the end of the stroke of the long groove 41.

[0073] By providing the limiting member 51 , the second rod 40 can be effectively prevented from being separated from the bracket 60 when the second rod 40 moves to the end of the travel of the long slot 41 , that is, when the second rod 40 extends the farthest distance relative to the bracket 60 .

[0074] Specifically, the limiting member 51 can be a limiting nail, which includes a rod body and a nail cap arranged at one end of the rod body, and the rod body can be inserted into the long slot 41 .

[0075] The long slot 41 is in the shape of a long strip, and the length and the setting position of the long slot 41 are adapted to the multiple locking holes 42 set on the other side of the second rod 40 .

[0076] Optionally, the adjustment mechanism 50 further includes an elastic member 54, and the elastic member 54 is used to reset the adjustment button 52 after being operated. By providing the elastic member 54, the limiting member 51 can also be in a state of connecting the second rod 40 and the base 100 under normal conditions, ensuring that the second rod 40 and the base 100 are relatively fixed under normal conditions.

[0077] The elastic member 54 may be disposed on the back side of the pressed surface of the adjustment button 52 to help the adjustment button 52 to reset after being pressed.

[0078] Optionally, the adjustment mechanism 50 further includes a gasket 55 , and the gasket 55 cooperates with the limiting member 51 to achieve a tight connection.

[0079] Optionally, the bracket 60 is Y-shaped, and the two forks of the bracket 60 are respectively connected to the corresponding second rod 40, and the middle extension part of the bracket 60 is installed in the base 100 and extends to the front end of the base 100. This can improve the stability and reliability of the connection between the ISOFIX connector 10 and the base 100, and improve the anti-rollover ability of the child safety seat.

[0080] like Figure 3 , Figure 8 and Fig. 9 As shown, the ISOFIX connection device for a child safety seat is characterized in that it also includes a limiting structure for limiting the maximum telescopic length of the second rod 40 relative to the base 100, thereby avoiding excessive adjustment of the second rod 40 relative to the base 100 and preventing the second rod 40 from detaching from the base 100.

[0081] There are many options for the specific structural form of the limiting structure. Optionally, the limiting structure includes a long groove 41 provided on the inner side of the second rod 40, and the above-mentioned limiting member 51 can be used as a specific implementation of the limiting structure. Through the cooperation of the long groove 41 and the limiting member 51, the maximum extension length or retraction length of the second rod 40 relative to the bracket 60 can be limited.

[0082] In the above-mentioned embodiments, the first rod 20, the second rod 40 and the bracket 60 may optionally but not limited to be hollow structures, which can reduce the overall weight of the child safety seat ISOFIX connection device and meet the lightweight design requirements.

[0083] Based on the above-mentioned child safety seat ISOFIX connection device, the present invention also proposes a child safety seat, which includes the above-mentioned child safety seat ISOFIX connection device. The positive technical effects of the child safety seat ISOFIX connection device in the above-mentioned embodiments are also applicable to child safety seats, which will not be repeated here.

[0084] Furthermore, the child safety seat also includes a base 100, the bottom surface of the base 100 is provided with a concave platform, and the ISOFIX connector 10 in the child safety seat ISOFIX connection device is stored in the concave platform after being folded. In this way, it can be ensured that the ISOFIX connector 10 does not protrude from the bottom surface of the base 100 after being folded, and the flatness of the bottom surface of the child safety seat is maintained.

[0085] The following is combined with Figures 1 to 9 The working process of an embodiment of the child safety seat ISOFIX connection device and the child safety seat of the present invention is described as follows:

[0086] like Figure 1 As shown, in normal use, the ISOFIX connector 10 is in an unfolded state; Figure 2As shown, when not in use, the ISOFIX connector 10 can be folded inward and stored in the recessed platform of the base 100 , and the step on the bottom surface of the base 100 can guide and control the folding limit of the ISOFIX connector 10 .

[0087] like Figure 3 to Figure 5 As shown, the child safety seat ISOFIX connection device includes an ISOFIX connector 10 , a first rod 20 , a rotating mechanism 30 , a second rod 40 , an adjusting mechanism 50 , a bracket 60 and an unlocking mechanism 70 .

[0088] The ISOFIX connector 10 is connected to the first rod 20, and the unlocking mechanism 70 is arranged on the ISOFIX connector 10. The first rod 20 is connected to the second rod 40, and a rotating mechanism 30 is arranged between the first rod 20 and the second rod 40. The first rod 20 can rotate relative to the second rod 40 to drive the ISOFIX connector 10 to fold inward. The second rod 40 is inserted into the bracket 60, and the second rod 40 is a hollow structure. The inner side of the second rod 40 is provided with a long groove 41, the outer side of the second rod 40 is provided with a plurality of locking holes 42, and the inner side of the bracket 60 is provided with a mounting hole 61.

[0089] The rotating mechanism 30 includes a sleeve 31 and a rivet 32. A first connecting hole is provided on the first rod 20, and a second connecting hole is provided on the second rod 40. After the first connecting hole and the second connecting hole are aligned, the sleeve 31 is inserted into the first connecting hole and the second connecting hole, and the rivet 32 ​​is inserted into the sleeve 31, so that the first rod 20 can rotate relative to the second rod 40.

[0090] like Figure 4 As shown, the ISOFIX connector 10 is in an unfolded state; Figure 5 As shown, the ISOFIX connector 10 is in a folded state.

[0091] The adjustment mechanism 50 includes a limiter 51, an adjustment button 52, an adjustment base 53, an elastic member 54 and a gasket 55. The limiter 51 passes through the adjustment base 53, the mounting hole 61 on the bracket 60 and is inserted into the long slot 41. The limiter 51 can slide in the long slot 41 to adjust the extension length of the second rod 40 relative to the bracket 60, and at the same time limit the maximum extension length of the second rod 40 to prevent the second rod 40 from detaching from the bracket 60 when the second rod 40 is extended to the maximum length relative to the bracket 60. The adjustment base 53 is in the shape of an arch, sleeved and installed on the bracket 60, the middle part of the adjustment button 52 is rotatably connected to the adjustment base 53, the first end of the adjustment button 52 is provided with a locking rod, and the second end is connected to the elastic member 54. Before the adjustment button 52 is pressed, under the action of the elastic member 54, the locking rod is inserted into the locking hole 42, so that the second rod 40 and the bracket 60 remain relatively fixed; after the second end of the adjustment button 52 is pressed, the adjustment button 52 rotates relative to the adjustment base 53, and the first end tilts upward, driving the locking rod to leave the locking hole 42, so that the second rod 40 is disconnected from the bracket 60. At this time, the locking rod is aligned with the other locking hole 42 by pulling the second rod 40 outward or pushing the second rod 40 inward, and then the adjustment button 52 is released. Under the action of the elastic member 54, the locking rod is reinserted into the corresponding locking hole 42, so that the second rod 40 and the bracket 60 are reconnected. At this point, the extension length of the second rod 40 relative to the bracket 60 is adjusted.

[0092] like Figure 6 As shown, the second rod 40 is in a retracted state relative to the bracket 60; Figure 7 As shown, the second rod 40 is in an extended state relative to the bracket 60. Figure 8 As shown, the adjustment button 52 is disposed on the outer side of the second rod 40; Fig. 9 As shown, the long slot 41 is arranged on the inner side of the second rod 40 , and the locking hole 42 is arranged on the outer side of the second rod 40 .

[0093] Based on the above structural setting, when in use, the extension length of the second rod 40 relative to the bracket 60 can be adjusted by adjusting the button 52, thereby adjusting the extension length of the ISOFIX connector 10 relative to the base 100 to adapt to the anchor point depths on different rear seats of the car; when storing, the second rod 40 can be retracted to the shortest by adjusting the button 52, and then the first rod 20 can be rotated inwardly 90° relative to the second rod 40, thereby driving the ISOFIX connector 10 to fold inwardly, so that the ISOFIX connector 10 is stored in the recessed platform of the base 100.

[0094] Through the description of multiple embodiments of the child safety seat ISOFIX connection device and the child safety seat of the present invention, it can be seen that the child safety seat ISOFIX connection device and the child safety seat of the present invention have at least one or more of the following advantages:

[0095] 1. A pair of ISOFIX connectors can be folded towards each other for storage, which is easy to operate, saves time and effort, and has good safety;

[0096] 2. By setting a safety limit structure, the ISOFIX connector can be prevented from accidentally folding;

[0097] 3. The extension length of the ISOFIX connector relative to the base is adjustable and has a wide range of applications;

[0098] 4. By setting a limit structure, the telescopic length of the second rod can be limited to prevent the second rod from detaching from the bracket.

[0099] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention, which should be included in the scope of the technical solution for protection of the present invention.
