When connecting the seat fixing rod on the seat group with the base group, the user does not need to perform additional corresponding operation on the hook. The user can place the seat fixing rod on the seat group in the guide slot, and the hook linkage mechanism is triggered by the seat group during the process of placing the seat fixing rod in the guide slot to release the locking action of the hook in the second use state. The hook switches from the second use state to the first use state and cooperates with the guide slot to lock the seat fixing rod, thereby realizing the automatic locking function. Therefore, only one connection action is required, which has the characteristic of convenient operation.

[0081] like Figure 3 , 4 As shown, in order to ensure the stability and reliability of the seat locking mechanism 5, the seat locking mechanism 5 also includes a safety locking mechanism 55, and the safety locking mechanism 55 is configured to lock the hook linkage mechanism 54 when the seat group 1 is connected and cooperated with the base group 2 to make the hook 53 enter the first use state.

[0082] Furthermore, in order to ensure a stable and reliable connection, the hook 53 is configured to have a rotation tendency to maintain elastic reset to the guide slot 52, and the hook linkage mechanism 54 is also configured so that when the seat group 1 is connected to the base group 2 or has not separated from the guide slot 52, the hook 53 is in a state of keeping the seat fixing rod 10 engaged and locked or maintaining a tendency to engage and lock the seat fixing rod 10.

[0083] like Figure 3 , 4 As shown, the hook linkage mechanism 54 includes a trigger linkage member 541, a trigger elastic member 542 and a linkage seat 543; the trigger linkage member 541 is movably arranged on the support seat 51 and is configured to be resisted by the seat group 1 when the seat group 1 is connected to the base group 2 and to move accordingly; the trigger elastic member 542 is located between the trigger linkage member 541 and the support seat 51 to drive the trigger linkage member 541 to automatically reset; the linkage seat 543 is movably located between the trigger linkage member 541 and the hook 5 3, a linkage seat limiting assembly 544 for limiting the movement of the linkage seat 543 is provided between the linkage seat 543 and the trigger linkage member 541, and the linkage seat limiting assembly 544 is configured to release the limitation of the linkage seat 543 when the trigger linkage member 541 is abutted by the seat group 1; a hook linkage assembly 545 for linking the hook 53 with the corresponding rotation movement is provided between the linkage seat 543 and the hook 53; the safety locking mechanism 55 is located between the trigger linkage member 541 and the linkage seat 543. When the seat group is connected to the base group so that the seat fixing rod is placed in the guide groove, the seat group presses the trigger linkage member to release the limitation of the linkage seat limiting assembly on the linkage seat 543 (i.e., release the locking state of the hook in the second use state), and the linkage seat 543 rotates correspondingly with the hook through the hook linkage assembly 545, so that the hook automatically resets and locks the seat fixing rod, which is convenient to operate and use.

[0084] like Figure 3 , 4As shown, in order to make the seat engagement mechanism 5 linkage accurate and reliable, the trigger linkage member 541 can be slidably arranged on the support seat 51 up and down, and the linkage seat 543 can be slidably located between the trigger linkage member 541 and the hook 53; the linkage seat limiting assembly 544 includes a linkage seat limiting vertical groove 5441 arranged on the trigger linkage member 541 or the linkage seat 543 and a linkage seat limiting rod 5442 arranged on the linkage seat 543 or the trigger linkage member 541 and limited by the linkage seat limiting vertical groove 5441. There is also a linkage seat transverse groove 5443 which is communicated with the linkage seat limit vertical groove 5441 and in which the linkage seat limit rod 5442 can move; the hook linkage assembly 545 includes a hook linkage vertical groove 5451 arranged on the linkage seat 543 or the hook 53 and a hook linkage rod 5452 arranged on the hook 53 or the linkage seat 543 and limitedly matched with the hook linkage vertical groove 5451; the safety locking mechanism 55 is formed by the corresponding side wall of the linkage seat transverse groove 5443 which is used to limitly match with the linkage seat limit rod 5442 to prevent the trigger linkage member 541 from sliding upward and resetting. When the seat group 1 is connected to the base group 2 so that the seat fixing rod 10 is placed in the guide groove 52, the seat group 1 presses the trigger linkage part 541 so that the trigger linkage part 541 drives the linkage seat limiting rod 5442 to slide downward relative to the support seat 51, thereby separating the linkage seat limiting rod 5442 from the linkage seat limiting vertical groove 5441 to release the restriction state of the linkage seat 543, and then the linkage seat 543 slides back to the support seat 51 along the front and rear directions, so that the linkage seat transverse groove 5443 and the linkage seat limiting rod 5442 slide in cooperation (at this time, the upper side wall of the linkage seat transverse groove 5443 and the linkage seat limiting rod 5442 block and cooperate to prevent the trigger linkage part 541 from sliding upward and returning to the original position), and at the same time, the hook linkage vertical groove 5451 cooperates with the hook linkage rod 5452 to drive the hook 53 to automatically return to the original position and lock the seat fixing rod 10, and the linkage is stable and reliable.

[0085] In addition, the linkage seat limit rod cooperates with the linkage seat limit vertical groove and the linkage seat limit rod respectively, and the hook linkage vertical groove cooperates with the hook linkage rod, which can play the role of guiding and limiting, ensuring the smooth and stable use of the corresponding parts of the utility model.

[0086] like Figure 3 , 4As shown, in order to facilitate unlocking, the base group 2 is movably provided with a hook unlocking mechanism 56 that can automatically reset. The hook unlocking mechanism 56 is configured to link each hook 53 to open simultaneously relative to the corresponding guide slot 52 to release the locking action of the seat fixing rod 10, and when the seat group 1 is connected to the base group 2, the hook unlocking mechanism 56 is released, so that each hook 53 automatically returns to the state of locking the seat fixing rod 10. The hook unlocking mechanism 56 includes a hook unlocking linkage frame 561 movably placed on the base group 2, and the hook unlocking linkage frame 561 is connected to the hook 53 on the support seat 51 located at the front and rear of the base group 2. A hook unlocking elastic member 562 is provided between the hook unlocking linkage frame 561 and the base group 2 for driving the hook unlocking linkage frame 561 to automatically reset. In this embodiment, the linkage seat 543 can be formed by the corresponding end of the unlocking linkage frame 561. Figure 4 As shown, the trigger linkage members 541 on the two support seats 51 at the front or rear are respectively connected by connecting rods. When the seat group 1 is connected to the base group 1, the seat group 1 presses the trigger linkage member 541 to ensure that the trigger linkage members 541 on the two support seats 51 slide smoothly and synchronously, while improving their structural strength. The hooks of the two support seats 51 are also connected by connecting rods to ensure that the hooks of the two front support seats 51 rotate synchronously, which is conducive to synchronous unlocking and locking. Figure 3 , 4 As shown, a seat unlocking handle 564 is movably provided on the base assembly 2 , and the seat unlocking handle 564 is connected to the hook unlocking linkage frame 561 through a seat unlocking pull rope 563 .

[0087] The difference between Example 2 in Scheme 1 and Example 1 in Scheme 1 is that, Fig.14 As shown, the child product further includes a connecting rod 4 with one end rotatably connected to the seat group 1. In the first use state, the connecting rod 4 can be used as a push rod of the child stroller. In the second use state, the connecting rod 4 is folded and moved closer to the seat group 1. In this embodiment, when the seat group 1 is separated from the base group 2 and in the use state of the basket, the connecting rod 4 is used as a handle bar of the basket.

[0088] Option 2:

[0089] like Figure 15-19As shown, the utility model is a multifunctional children's product with easy use, comprising: a seat frame 100, a child safety seat body 200, a base group 2 and a frame group 3; the seat frame 100 is used for infants and young children to sit on, and the seat frame 100 is configured to have a five-point safety belt and can be rotated, folded and unfolded; the child safety seat body 200 is used for infants and young children to sit on; the base group 2 is configured to be selectively detachably connected to the seat frame 100 or the child safety seat body 200; the frame group 3 is connected to the base group 2, and the frame group 3 has an unfolded use state and a folded use state relative to the base group 2; when the base group 2 is selected to be connected to the seat frame 100, the seat frame 100 and the frame group 3 are in an unfolded state, so that the children's product is switched to a simple baby stroller mode; when the base group 2 is selected to be connected to the child safety seat body 200, the frame group 3 is in an unfolded state, so that the children's product is switched to a child stroller mode.

[0090] In the child stroller mode, when the child safety seat body 200 is separated from the base assembly 2, the child safety seat body 200 can be converted into a carrier for independent use or connected to a safety seat base and restrained on a car seat accordingly.

[0091] Since the base group in the utility model can be selectively connected to the seat frame to switch the child product to a simple baby stroller mode, and can also be selectively connected to the child safety seat body to switch the child product to a child stroller mode, at the same time, in the child stroller mode, the child safety seat body is separated from the base group to convert the child safety seat body into a carry basket for independent use or connected to the safety seat base to be restrained on the car seat. Therefore, the utility model can switch to the corresponding use mode according to different usage scenarios, and has the characteristics of fast switching, multi-function, strong applicability and easy carrying. In addition, it also has the characteristics of simple structure and overall lightweight.

[0092] The base assembly 2 in the second solution adopts a lightweight structure and can be integrally injection molded, which cannot meet the structural strength requirements of the child safety seat base.

[0093] like Figure 15-17 As shown, in order to facilitate transportation and packaging, when the children's product is switched to a simple stroller mode, the seat frame 100 and the frame assembly 3 can be folded relative to the base assembly 2 to form a complete vehicle, and a cavity for accommodating the seat frame 100 is provided on the upper surface of the base assembly 2. When the seat frame 100 is folded, it can be placed in the cavity, making the folded structure more compact.

[0094] like Figure 15-17As shown, for reliable locking, the seat frame 100 includes a seat plate 110 detachably connected to the base assembly 2 and a back plate 120 rotatably connected to the rear end of the seat plate 110, and a back plate locking mechanism 130 for locking the back plate 120 relative to the seat plate 110 is provided between the back plate 120 and the seat plate 110. Fig.16 As shown, the back panel locking mechanism 130 includes a backrest blocking portion arranged at the lower end of the back panel 120. When the back panel 120 is flipped backward relative to the seat panel 110 to an unfolded use state, the backrest blocking portion abuts against the rear end of the seat panel 110 to block and limit the back panel 120 from continuing to flip backward relative to the seat panel 110, and has the characteristics of reasonable and simple structure.

[0095] like Fig.15 , 16 As shown, in order to better lock the seat frame 100 relative to the base assembly, a seat frame locking mechanism 300 for locking the seat frame 100 relative to the base assembly 2 is provided between the seat frame 100 and the base assembly 2, and the seat frame locking mechanism 300 includes a seat frame locking hole 310 provided on the base assembly 2 and a seat frame locking tongue 320 which can be elastically slidably provided on the seat frame 100 and can be inserted into the seat frame locking hole 310.

[0096] like Fig.18 , 19 As shown, in order to better lock the child safety seat body 200 relative to the base assembly, a seat body locking mechanism 400 for locking the child safety seat body 200 relative to the base assembly 2 is provided between the child safety seat body 200 and the base assembly 2. The seat body locking mechanism 400 includes a seat body locking hole 410 provided on the base assembly 2 and a seat body locking tongue 420 slidably provided on the child safety seat body 200 and insertable into the seat body locking hole 410 to lock the child safety seat body 200 relative to the base assembly, and a seat body locking reset member 430 for driving the seat body locking tongue 420 to automatically reset is provided between the seat body locking tongue 420 and the child safety seat body 200. In order to facilitate unlocking, a seat body unlocking member is movably provided on the child safety seat body 200, and the seat body unlocking member is connected to the corresponding seat body locking tongue 420 through a seat body unlocking pull rope.

[0097] The related structures of the frame assembly, connecting rods, etc. in this scheme 2 can adopt the structure of scheme 1, and will not be repeated here.
