[0034] It should be noted that the features in the embodiments of the present application can be combined with each other without conflict.

[0035] As described in the background art, a child safety seat is a safety device specifically designed for children of different ages or body types. Installed in a vehicle, it can effectively improve the safety of children when riding. The ISOFIX system refers to a structure for connecting a child safety seat to a vehicle seat. When installing a child safety seat, since the child safety seat is only connected to the vehicle seat through the ISOFIX system, if the ISOFIX system is not installed in place, there will be a greater safety hazard.

[0036] In the prior art, to check whether the ISOFIX system is installed in place, the user usually pulls and tugs after the child safety seat is installed to make a judgment. However, the child safety seat itself has a certain weight, and the method of pulling and tugging is time-consuming and laborious.

[0037] In view of this, referring to Figures 1-5 , the ISOFIX system with self-checking working status provided in the embodiments of the present application, that is, the child safety seat, can solve this problem, and a detailed description thereof will be given below.

[0038] See Figure 1 and Figure 2 , an embodiment of the present utility model provides an ISOFIX system with self - checkable working state, including a housing 1, a prompt button 2 and a chuck 3.

[0039] Among them, the housing 1 is in a long strip shape, and a bayonet 11 for clamping the connecting component of the vehicle seat is provided at one end of one side thereof; the prompt button 2 is installed on the outer side wall of the housing 1 and has a reset state and a pressed state; the chuck 3 is rotatably connected to the housing 1 and is in transmission connection with the prompt button 2, and has a locking state and an unlocking state. Since the chuck 3 is installed inside the housing 1, it has better structural stability and aesthetics, so it is taken as a further preference.

[0040] When the chuck 3 is in the locking state, one side of the chuck 3 rotates and clamps into the bayonet 11 to engage with the connecting component of the vehicle seat, and the prompt button 2 is in the reset state and gives a warning; when the chuck 3 is in the unlocking state, the chuck 3 rotates away from the bayonet 11 to separate from the connecting component of the vehicle seat, and the prompt button 2 is in the pressed state and stops warning. Thus, the ISOFIX system judges whether it is installed in place through the warning of the prompt button 2, thereby realizing self - check.

[0041] See Figure 3 and Figure 4 , the housing 1 of this embodiment is mainly composed of a front half - shell 1a and a rear half - shell 1b spliced together, so as to facilitate the disassembly and assembly of the chuck 3 inside it. In addition, it can also be assembled with other structures that are convenient for disassembly and assembly. In order to further increase the structural stability between the front half - shell 1a and the rear half - shell 1b, they can also be further fixedly connected by fasteners such as bolts.

[0042] Optionally, see Figure 4 and Figure 5 , the prompt button 2 includes a button base 21 and a button body 22. The button base 21 is fixed on one side of the housing 1. The button base 21 can be fixed by fasteners such as bolts or fixed by adhesives such as glue, mainly to provide good support for the button body 22. In this embodiment, the button base 21, the front half - shell 1a and the rear half - shell 1b are fixed by passing through the same bolt.

[0043] A part of the button body 22 is inserted into the button base 21. Thus, the button body 22 can slide horizontally (in the direction parallel to the X - axis) under the limiting action of the button base 21. Another part of the button body 22 extends outside the button base 21 and is in transmission connection with the chuck 3. Thus, during the sliding process of the button body 22, the chuck 3 rotates accordingly.

[0044] Since the light inside the vehicle is usually poor and the feedback signal given by ordinary warnings to the user is weak, the prompting button 2 of this embodiment further includes a sound prompter 23 and a light prompter 24 installed in the button base 21. Correspondingly, a light-transmitting opening 211 for the light of the light prompter 24 to pass through is provided on the button base 21, or a button base 21 made of a light-transmitting material is selected. The drawings of this embodiment are shown taking the former as an example. When the chuck 3 is in the locked state, the sound prompter 23 and the light prompter 24 give sound and light reminders at the same time, giving the user a clearer feedback and a full sense of security.

[0045] On this basis, since the prompting button 2 is provided outside the housing 1, its warning effect is more obvious and effective. There are many types of the sound prompter 23 and the light prompter 24, as long as they can achieve the corresponding warning effect. The sound prompter 23 of this embodiment is specifically shown taking a buzzer as an example, and the light prompter 24 is specifically shown taking a lamp bead as an example. The lamp bead is inserted into the light-transmitting opening 211 so as to facilitate checking whether the lamp bead is lit.

[0046] Optionally, in order to achieve the simultaneous warning of the sound prompter 23 and the light prompter 24, the prompting button 2 of this embodiment further includes a circuit board 25 installed in the button base 21, a power supply 26 and a switch 27 connected to the circuit board 25. The sound prompter 23 and the light prompter 24 are installed on the circuit board 25. Thus, when the chuck 3 is in the locked state, the switch 27 is closed, and the power supply 26 supplies power to the sound prompter 23 and the light prompter 24 through the circuit board 25, which has the characteristics of simple structure and convenient operation.

[0047] Optionally, referring to Figure 3 and Figure 4 , the ISOFIX system of this embodiment further includes a connecting member 4. The structure of the connecting member 4 can be adjusted according to the shape of the housing 1, and is specifically shown in a strip structure in the figure. One end of the connecting member 4 is vertically connected with a connecting shaft 41. One end of the connecting shaft 41 extends out of the housing 1 and is fixedly connected to the button body 22. A kidney-shaped hole 12 for the connecting shaft 41 to slide along the pressing direction of the prompting button 2 (the direction parallel to the X axis) is provided on the housing 1. Thus, when the button body 22 is pressed, the connecting member 4 horizontally slides along with the connecting shaft 41. In order to further improve the installation efficiency of the connecting member 4, the connecting shaft 41 of this embodiment is a bolt, and the bolt passes through the rear half shell 1b, the connecting member 4 and the front half shell 1a in sequence and is fixedly connected to the button body 22. The kidney-shaped holes are symmetrically provided on both the front half shell 1a and the rear half shell 1b so that the bolt is suitable for horizontal sliding inside the housing 1.

[0048] Optionally, the housing 1 is provided with an anti-rotation shaft 13 on the inner side wall of the rear half housing 1b. The anti-rotation shaft 13 is arranged in parallel and at an interval with the connecting shaft 41. The connecting member 4 is installed in the housing 1. The anti-rotation shaft 13 is limited above the middle part of the connecting member 4. Thus, the connecting member 4 is limited at two points through the anti-rotation shaft 13 and the connecting shaft 41, which helps to further increase the stability during the sliding process of the connecting member 4.

[0049] Optionally, referring to Figure 2 and Figure 3 , in order to realize the interlocking between the prompt button 2 and the chuck 3, the ISOFIX system of this embodiment further includes a return spring 5. One end of the return spring 5 is connected to the middle position of the connecting member 4, and the other end of the return spring 5 is connected to the chuck 3. The button body 22 of the prompt button 2 returns from the pressed state to the reset state through the return spring 5. Correspondingly, the chuck 3 also returns from the unlocked state to the locked state.

[0050] Optionally, the housing 1 is further provided with a rotating shaft 14 and a limiting shaft 15 on the inner side wall of the rear half housing 1b. The rotating shaft 14 and the limiting shaft 15 are located on the side of the housing 1 where the bayonet 11 is provided. The two are arranged in parallel and at an interval, and the other ends of both are fixedly passed through the front half housing 1a of the housing 1, thereby increasing its structural stability. The chuck 3 is provided with a rotating hole 31 for the rotating shaft 14 to pass through. The limiting shaft 15 abuts against the chuck 3 to limit the rotation of the chuck 3 when it is in the locked state. The chuck 3 is further provided with a fastening port 32, and the connecting member 4 is provided with a fastening tongue 42 adapted to the fastening port 32. The chuck 3 is provided with a guiding edge 33 at the opening edge of the fastening port 32 for guiding the fastening tongue 42 to be inserted into or disengaged from the fastening port 32.

[0051] The implementation principle of this embodiment is as follows:

[0052] When the prompt button 2 is pressed, the button body 22 drives the connecting member 4 to slide horizontally to the left (in the direction parallel to the positive X-axis) through the connecting shaft 41. The fastening tongue 42 slides out of the fastening port 32 along the guiding edge 33, and the return spring 5 is stretched, thereby driving the chuck 3 to rotate to the unlocked state. At this time, the switch 27 in the prompt button 2 is disconnected, so that no sound and light warning is issued, that is, the prompt button 2 is in the pressed state.

[0053] When the pressing force on the prompt button 2 is released, the restoring force of the return spring 5 pulls the connecting member 4 to slide horizontally to the right (in the direction parallel to the negative X-axis), thereby driving the button body 22 to reset. The fastening tongue 42 is guided along the guiding edge 33 and is snapped into the fastening port 32 to realize the fastening with the chuck 3. In this way, the chuck 3 is in the locked state. At this time, the switch 27 in the prompt button 2 is closed, so that a sound and light warning is issued, that is, the prompt button 2 is in the reset state.

[0054] In summary, when the ISOFIX system is installed in place in this embodiment, it will give both audible and visual reminders simultaneously, providing clear feedback and a full sense of security to the user. Especially in scenarios with weak light, the advantages of this technical point are particularly obvious.

[0055] Another embodiment of the present utility model provides a child safety seat, which includes the ISOFIX system whose working state can be self-checked in the above embodiment. Compared with the prior art, it has the same advantages as above and will not be elaborated here.

[0056] Although the present disclosure is disclosed as above, the protection scope of the present disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will all fall within the protection scope of the present utility model.
