Description

Technical Field

[0001] The utility model relates to an infant product, in particular to a child seat and a child stroller provided with the seat. Background Art

[0002] A child stroller is mainly used for infants and young children to ride in. A traditional child stroller includes a frame and a seat arranged on the frame. Some seats are detachably and reversibly connected to the child stroller frame through a mounting seat, that is, the seat is connected to the mounting seat, and the mounting seat is detachably connected to the child stroller frame. After the seat and the mounting seat are removed from the frame, the mounting seat can be detachably connected to the frame again by reversing the front and back directions.

[0003] Some seats are fixedly connected to the mounting seat, so that during use, the seat cannot be adjusted relative to the mounting seat, that is, relative to the frame, making the use of the seat inconvenient. In addition, in order to make the use more convenient, the frame and the seat can be folded, but due to structural reasons, in order to prevent the seat from interfering with the folding of the frame, the existing child stroller either needs to remove the seat from the frame before folding, or the seat must be in one of the forward and rearward positions to avoid interfering with the folding of the frame after the seat is folded. If it is in the other direction, the seat will still interfere with the folding of the frame even after folding, so before the frame is folded, it is necessary to ensure that the seat is in the specified direction. In this way, the folding operation of the entire child stroller is very cumbersome. Utility Model Content

[0004] The purpose of the present invention is to overcome the above-mentioned disadvantages and to provide a child seat and a child stroller provided with the seat. No matter whether the child seat is in the forward position or the rearward position, it can be rotated to an angle position after being folded so as not to interfere with the folding of the child stroller frame, thereby making the overall folding operation of the child stroller of the present invention very simple.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A child seat which can be switched between an expanded state and a folded state, and the child seat is connected to a child stroller frame via a mounting seat in a detachable and forward and backward reversible manner; the child seat is rotatably connected to the mounting seat, and a locking mechanism for limiting relative rotation between the two and a limiting mechanism for limiting the relative rotation angle between the two are provided between the child seat and the mounting seat; the locking mechanism and the limiting mechanism are configured so that the locking mechanism and the limiting mechanism can be unlocked in a linked manner during the folding process of the child seat.

[0007] A first linkage device is further provided between the child seat and the locking mechanism. One side of the first linkage device is cooperatively arranged with the locking mechanism, and the other side is cooperatively arranged with the child seat; during the folding process of the child seat, the first linkage device can be linked to unlock the locking mechanism.

[0008] The child seat includes a first frame and a second frame pivotally connected to opposite sides. During the folding process of the child seat, the second frame rotates relative to the first frame; preferably, both the locking mechanism and the limiting mechanism are arranged between the first frame and the mounting seat; preferably, when the second frame rotates relative to the first frame, the locking mechanism and the limiting mechanism can be linked to be unlocked; preferably, the other side of the first linkage device is cooperatively arranged with the second frame, and when the second frame rotates relative to the first frame, the first linkage device can be linked to unlock the locking mechanism.

[0009] The first linkage device includes a driving part arranged on the second frame and a linkage member rotatably cooperatively arranged with the locking mechanism. A linkage part is arranged on the side of the linkage member facing the second frame, and the linkage part is cooperatively arranged with the driving part; when the second frame rotates relative to the first frame, the linkage member is driven to rotate through the cooperation between the driving part and the linkage part to unlock the locking mechanism.

[0010] The second frame and the mounting seat are respectively pivotally connected to the left and right sides of the first frame; the locking mechanism includes a first tooth groove, a second tooth groove respectively arranged on the opposite sides of the first frame and the mounting seat, a gear movably connected in the first tooth groove and the second tooth groove, and a first elastic member arranged between the first tooth groove and the gear. Under the action of the first elastic member, the gear meshes with the first tooth groove and the second tooth groove at the same time, and the locking mechanism is in a locked state.

[0011] A blocking part is arranged on the second frame, and the blocking part and the limiting mechanism are arranged such that when the child seat is in the unfolded state, the blocking part contacts the limiting mechanism, so that the limiting mechanism remains in the locked state; when the second frame rotates relative to the first frame until its blocking part is separated from the limiting mechanism, the limiting mechanism is unlocked.

[0012] A baby stroller includes a foldable frame, and further includes the child seat as described above. The child seat is detachably connected and can be connected to the frame in a front-back reversible manner through a mounting seat.

[0013] Because the present utility model adopts the above technical solutions, the following beneficial effects are achieved:

[0014] 1. Regardless of whether the child seat is in the forward position or the rearward position, it can be rotated relative to the frame to an angle position that does not interfere with the folding of the child stroller frame after being folded. Therefore, before the frame is folded, there is no need to remove the child seat from the frame, nor is there any need to adjust the child seat to a required orientation position, thereby making the overall folding operation of the child stroller of the utility model very simple;

[0015] 2. When the child seat is folded, the locking mechanism for limiting the relative rotation between the child seat and the mounting seat can be unlocked, and the limiting mechanism for limiting the rotation angle of the seat relative to the mounting seat can also be unlocked, so that the folding operation of the seat as a whole is also very simple, thus further simplifying the folding operation of the child stroller as a whole of the utility model;

[0016] 3. The seat and the mounting seat can be relatively rotatable. When the child seat is in use, the locking mechanism can be unlocked by the unlocking device to adjust the inclination angle of the child seat relative to the mounting seat, so that the child seat is more convenient to use; and when doing so, it will not affect the first linkage device and will not cause the seat to be folded, thereby ensuring the safety of the child seat in use;

[0017] 4. The setting of the limiting mechanism ensures that even if the child seat is adjusted to rotate relative to the frame, it can only rotate within the angle limited by the limiting mechanism and cannot rotate infinitely, thereby further ensuring the safety of the child seat in use.

[0033] like Figure 1 , 2 As shown, the utility model discloses a child seat 1, which can be converted between an unfolded state and a folded state, and the child seat 1 is detachably and front-to-rear reversibly connected to a child stroller frame 3 through a mounting seat 2; the child seat 1 is rotatably connected to the mounting seat 2, and a locking mechanism for limiting the relative rotation of the two and a limiting mechanism for limiting the relative rotation angle of the two are provided between the child seat 1 and the mounting seat 2; and the locking mechanism and the limiting mechanism are configured so that the child seat 1 can be linked to unlock the locking mechanism and the limiting mechanism during the folding process.

[0034] A first linkage device is also provided between the child seat 1 and the locking mechanism. One side of the first linkage device is provided in cooperation with the locking mechanism, and the other side of the first linkage device is provided in cooperation with the child seat 1. During the folding process of the child seat 1, the first linkage device can drive the first linkage device to unlock the locking mechanism.

[0035] The child seat 1 comprises a first frame 11 and a second frame 12 pivotally connected at opposite sides. During the folding process of the child seat 1, the second frame 12 rotates relative to the first frame 11. The locking mechanism and the limiting mechanism are both arranged between the first frame 11 and the mounting seat 2, and the other side of the first linkage device is arranged in cooperation with the second frame 12. During the folding process of the child seat, the second frame 12 rotating relative to the first frame 11 drives the first linkage device to unlock the locking mechanism.

[0036] In this embodiment, the second frame 12 and the mounting seat 2 are respectively pivotally connected to the left and right sides of the first frame 11. Preferably, the first frame 11, the second frame 12, and the mounting seat 2 are coaxially pivotally connected, so that the assembly operation is easier.

[0037] The first linkage device includes a driving part 120 arranged on the second frame 12 and a linkage member 4 arranged in cooperation with the locking mechanism, wherein a linkage part 41 is arranged on the side of the linkage member 4 facing the second frame 12, and the linkage part 41 is arranged in cooperation with the driving part 120; during the folding process of the child seat 1, the second frame 12 rotating relative to the first frame 11 drives the linkage member 4 to rotate through the cooperation between the driving part 120 and the linkage part 41 to unlock the locking mechanism.

[0038] In this embodiment, the driving portion 120 is a driving hole provided on the second frame 12, and the linkage portion 41 can be relatively rotatably inserted into the driving hole 120. Therefore, during the rotation of the second frame 12, when the side wall of the driving hole 120 is rotated to contact the linkage portion 41, the second frame 12 continues to rotate, which can drive the linkage portion 41 to rotate together, that is, drive the linkage member 4 to rotate together, and the rotating linkage member 4 can drive the locking mechanism to unlock.

[0039] Preferably, the first frame 11 is provided with a through hole 110 at a corresponding position, and the linkage part 41 can be relatively rotatably passed through the through hole 110 and then inserted into the driving hole 120. In this way, the linkage member 4 is located within the first frame 11, the second frame 12 and the mounting seat 2, and does not leak out, thereby preventing the linkage member 4 from being interfered with by foreign objects and affecting the folding of the seat and the linkage unlocking of the locking mechanism.

[0040] Furthermore, in order to make the force on the linkage member 4 more uniform, two driving holes 120 are symmetrically provided, and two linkage parts 41 are correspondingly provided, and the two linkage parts 41 extend into the two linkage members 4 respectively.

[0041] In this embodiment, the locking mechanism includes a first tooth groove 111 and a second tooth groove 21 arranged on opposite sides of the first frame 11 and the mounting base 2, a gear 5 relatively movably connected to the first tooth groove 111 and the second tooth groove 21, and a first elastic member (not shown) arranged between the first tooth groove 111 and the gear 5. Under the action of the first elastic member, the gear 5 is simultaneously engaged with the first tooth groove 111 and the second tooth groove 21, and the locking mechanism is in a locked state, and the child seat and the mounting base 2 cannot rotate relative to each other.

[0042] The linkage 4 and the gear 5 are rotatably matched, and the cooperation between the two is configured so that when the linkage 4 is driven to rotate by the rotating second frame 12 during the folding process of the child seat, the gear 5 can be driven to move into the first tooth groove 111 and disengage from the second tooth groove 21, thereby unlocking the locking mechanism, so that the child seat as a whole can rotate relative to the mounting base 2.

[0043] Specifically, the linkage member 4 is relatively rotatable and is located in the inner ring of the gear 5, and a boss 51 is convexly provided on the inner wall of the gear 5, and a driven inclined surface 52 is provided on the side of the boss 51 away from the first tooth groove 111; a groove is provided on the outer wall of the linkage member 4, and the side wall of the groove is provided as an active inclined surface 42, the boss 51 is adapted to the groove, and the active inclined surface 42 is adapted to the driven inclined surface 52. When the linkage member 4 rotates, the gear 5 is driven to move into the first tooth groove 111 through the cooperation of the active inclined surface 42 and the driven inclined surface 52.

[0044] Preferably, an arc groove 53 is provided on the end surface of the gear 5 facing the second tooth groove 21, and correspondingly, a protrusion 43 is provided on the linkage member 4, and the protrusion 43 extends out of the linkage member 4 and is relatively rotatably located in the arc groove 53. The arrangement of the arc groove 53 and the protrusion 43 can prevent mistakes during assembly and assist in quickly and correctly assembling the gear and the linkage member 4.

[0045] The linkage portion 41 is disposed on a side facing the second frame 12 , and the through hole 110 is disposed on a bottom wall of the first tooth groove 111 .

[0046] Preferably, the mounting seat 2 is also movably connected with an unlocking device for unlocking the locking mechanism, and the unlocking device, the locking mechanism and the first linkage device are configured so that when the child seat is in the unfolded state, when the locking mechanism is unlocked by the unlocking device, the first linkage device remains stationary. That is to say, the locking mechanism can be unlocked when the child seat is folded, but when the child seat is in use, when the locking mechanism is unlocked by the unlocking device and the inclination angle of the child seat relative to the mounting seat 2 is adjusted, the first linkage device will not be affected and the seat will not be folded, thereby ensuring the safety of the seat in use.

[0047] In this embodiment, the unlocking device includes a button 20 movably connected to the mounting base 2 in a left-right direction. One side of the button 20 extends into the second tooth groove 21 and abuts against the gear 5. Pressing the button 20 in the direction towards the first tooth groove 111 can push the gear 5 to move into the first tooth groove 111 and disengage from the second tooth groove 21, thereby unlocking the locking mechanism.

[0048] Preferably, the cooperation between the linkage 4 and the gear 5 is also set such that when the child seat 1 is in the unfolded state, when the gear 5 is driven to move into the first tooth groove, the linkage 4 remains stationary, that is, only when the linkage 4 is driven to rotate by the first frame 11 can it drive the gear 5 to move, but the movement of the gear 5 will not drive the linkage 4.

[0049] The second tooth groove 21 is provided on the upper side of the mounting base 2, and the lower side of the mounting base 2 is connected to the vehicle frame 3.

[0050] Combined Figures 9 - 11 As shown, a blocking portion 121 is provided on the second frame 12, and the blocking portion 121 and the limiting mechanism are set such that when the child seat is in the unfolded state, the blocking portion 121 contacts the limiting mechanism, so that the limiting mechanism remains in the locked state; when the second frame 12 rotates relative to the first frame 11 until its blocking portion 121 disengages from the limiting mechanism, the limiting mechanism is unlocked.

[0051] The limiting mechanism includes a first limiting group and a second limiting group 22 which are cooperatively arranged. The first limiting group is movably connected to the first frame 11, and the second limiting group is provided on the mounting base 2; when the first limiting group and the second limiting group 22 cooperate with each other, the limiting mechanism is in the locked state, and when the two are disengaged from each other, the limiting mechanism is unlocked.

[0052] By the contact or disengagement of the blocking portion 121 with the first limiting group, the first limiting group can be kept in a state of cooperating with the second limiting group 22 or move relative to the first frame 11 to disengage from the cooperation with the second limiting group 22. Specifically, when the child seat 1 is in the unfolded state, the blocking portion 121 contacts the first limiting group to limit the movement of the first limiting group relative to the first frame 11, so that the first limiting group remains in a state of cooperating with the second limiting group 22, and thus the limiting mechanism is in the locked state; during the folding process of the child seat, when the second frame 12 rotates relative to the first frame 11 until its blocking portion 121 disengages from the first limiting group, the first limiting group can move relative to the first frame 11 to disengage from the cooperation with the second limiting group 22, and the limiting mechanism is unlocked.

[0053] The first limiting group includes a limiting member 61 movably connected to the first frame 11 relative to left and right, a second elastic member 62 disposed between the limiting member 61 and the first frame 11, and an acting member 63 disposed on a side of the limiting member 61 facing away from the mounting base 2 and movably connected to the first frame 11 in a mating manner. The second elastic member 62 can drive the limiting member 61 to move toward the side away from the mounting base 2. By the contact or disengagement of the blocking portion 121 and the acting member 63, the limiting member 61 can be maintained in a state of mating with the second limiting group 22 or move relative to the first frame 11 to disengage from the mating with the second limiting group 22.

[0054] Specifically, when the child seat 1 is in the unfolded state, the blocking portion 121 contacts the acting member 63, and the acting member cannot move toward the direction of the blocking portion 121. As a result, the limiting member 61 cannot move relative to the first frame either. Therefore, the limiting member 61 is maintained in a state of mating with the second limiting group 22, and the limiting mechanism is in the locked state. After the blocking portion 121 is disengaged from the acting member 63, the blocking portion 121 no longer blocks the movement of the acting member. Under the action of the second elastic member 62, the limiting member 61 moves relative to the first frame 11. Due to the cooperation between the acting member 63 and the limiting member 61, when the limiting member 61 moves relative to the first frame 11, it can push the acting member 63 to move in the direction where the blocking portion was before the second frame rotated. When one side of the limiting member 61 is disengaged from the mating with the second limiting group 22, the locking mechanism is unlocked.

[0055] In this embodiment, the second limiting group 22 is an arc-shaped limiting groove 22 provided on the mounting base 2 and extending in the front-rear direction. The locking and unlocking of the limiting mechanism are achieved by the limiting member 61 extending into or disengaging from the arc-shaped limiting groove 22.

[0056] The acting member 63 and one side of the limiting member 61 are respectively provided with a mating first inclined surface 630 and second inclined surface 610. Through the mutual cooperation of the first inclined surface 630 and the second inclined surface 610, when either the acting member 63 or the limiting member 61 moves, the other can also move relative to the first frame 11.

[0057] Preferably, the limiting member includes a limiting seat 611 movably connected to the first frame in the left-right direction, a limiting pin 612 movably connected to the limiting seat 611 in the left-right direction, and a third elastic member 60 disposed between the limiting pin 612 and the limiting seat 611 to drive the limiting pin 612 to move toward the mounting seat 2. The locking and unlocking of the limiting mechanism are achieved by one side of the limiting pin 612 extending into or disengaging from the arc-shaped limiting groove 22. The acting member 63 is cooperatively arranged with the limiting seat 611, and the second elastic member 62 is disposed between the limiting seat 611 and the first frame 11. With such an arrangement, if the rotation angle of the child seat relative to the mounting seat is greater than the angle limited by the limiting mechanism, the limiting pin 612 will be outside the front or rear side of the arc-shaped limiting groove 22, rather than facing the arc-shaped limiting groove 22. Thus, when the child seat after unfolding and folding is rotated in the reverse direction, when the second frame 12 rotates until its blocking portion 121 contacts the portion of the acting member 63 extending out of the accommodating cavity, and the second frame 12 continues to rotate, the blocking member will push the acting member 63 to move into the accommodating cavity. Thus, through the cooperation of the first inclined surface and the second inclined surface, the limiting seat 611 will be driven to move toward the mounting seat 2, so that the limiting pin 612 also moves toward the mounting seat and extends out of the through hole 114. If the portion of the limiting pin 612 extending out of the through hole contacts the outer wall of the arc-shaped limiting groove 22, the outer wall will push the limiting pin 612 to move toward the limiting seat 611 and compress the third elastic member 60. When the limiting pin 612 faces the arc-shaped limiting groove 22 as the second frame 12 rotates, the restoring force of the third elastic member 60 drives the limiting pin 612 to move toward the mounting seat and extend into the arc-shaped limiting groove 22, and the limiting mechanism is in the locked state again.

[0058] In this embodiment, the limiting seat 611 is provided with a receiving cavity, and long holes 6111 extending in the left-right direction are provided on two opposite side walls of the receiving cavity; one side of the limiting pin 612 extends into the receiving cavity, and a pin shaft 6121 passes through the long hole 6111 and the limiting pin 612, so as to achieve the purpose of movably connecting the limiting pin and the limiting seat. The third elastic member 60 is disposed between the limiting pin 612 and the corresponding wall portion of the receiving cavity.

[0059] Preferably, a receiving portion 112 extending left and right is provided on the first frame 11. A receiving cavity 113 is provided in the receiving portion 112. A through hole 114 is provided on the side wall of the receiving cavity 113 facing the mounting base. The limiting member 61 and the second elastic member are placed in the receiving portion 112, and one side of the limiting member (the limiting pin 612 in the limiting member) can pass through the through hole 114 and extend into the arc-shaped limiting groove 22; a through hole is provided on the side wall of the receiving portion 112 facing the second frame 12. The acting member 63 is movably located in the receiving cavity 113, and one side thereof facing the second frame 12 can extend out of the receiving cavity 113 through the through hole. The acting member can be arranged such that when one side thereof facing the second frame 12 is flush with the upper end of the through hole, it contacts the blocking portion 121, or it can be arranged such that after one side thereof facing the second frame 12 extends out of the upper end of the through hole by a certain distance, it contacts the blocking portion 121. However, no matter which kind of contact, once the blocking portion 121 leaves, the acting member 63 will be driven by the moving limiting member and continue to move out of the through hole.

[0060] The side of the receiving portion 112 facing away from the mounting base is open, and a lid 66 is detachably connected to the receiving portion 112 to close the receiving cavity 113, thus facilitating the assembly of the first limiting assembly into the receiving cavity 113 and making the assembly more convenient.

[0061] In this embodiment, a guiding plate 117 protrudes from the first frame 11, and the lower side of the guiding plate 117 is arc-shaped; correspondingly, on the lower side of the mounting base 2, a guiding member 123 extends outward and upward on the side facing the first frame 11. A guiding groove 124 is formed between the corresponding portions of the guiding member 123 and the mounting base 2. When the child seat rotates relative to the mounting base 2, the lower side of the guiding plate 117 can rotate along the guiding groove 124. With such a setting, the relative rotation between the child seat and the mounting base is smoother.

[0062] Both the left and right sides of the child seat 1 are connected to the mounting base 2, that is to say, the corresponding sides of the left and right sides of the first frame 11 and the second frame 12 are respectively pivotally connected to a mounting base 2, and a locking mechanism and a limiting mechanism are provided between the left and right sides of the first frame and the corresponding mounting bases 2, and a first linkage device is provided between the right and left sides of the second frame and the corresponding locking mechanisms.

[0063] In this embodiment, both the first frame 11 and the second frame 12 are arranged in a U shape, and the open ends of the two U shapes are pivotally connected to each other relatively.

[0064] The child seat 1 further includes an armrest 16, which is detachably connected to the first frame 11 or the second frame 12. Before the seat is folded, the armrest 16 can be detached first. Preferably, the armrest 16 is detachably connected to the side of the second frame 12 facing away from the first frame 11. In other embodiments, the armrest 16 can also be pivotally connected to the second frame 12. When the child seat 1 is folded, the armrest 16 can also rotate to a state close to the first frame 11 and the second frame 12. The specific connection between the armrest 16 and the first frame 11 or the second frame 12 can be any well-known and feasible structure, and it is not the inventive point of the present utility model, so it will not be elaborated here.

[0065] Specifically, an armrest seat 161 is connected to the side of the second frame 12 facing away from the first frame 11, and the armrest 16 is detachably connected to the armrest seat 161; or, the armrest seat 161 is pivotally connected to the second frame 12, and the armrest 16 is connected to the armrest seat 161, so as to achieve the purpose of being pivotally connected to the second frame 12.

[0066] In this embodiment, the child seat further includes a first connecting rod 13, a second connecting rod 14 and a third connecting rod 15. One side of the first connecting rod 13 and the third connecting rod 15 is pivotally connected to the first frame 11 at intervals, the upper side of the second connecting rod 14 is pivotally connected to the first connecting rod 13, and the lower side is pivotally connected to the third connecting rod 15. In this way, when the seat is in the use state, the third connecting rod 15 can be used as a seat tube, and the first connecting rod 13 and the second connecting rod 14 can play a role in pulling the seat tube. Moreover, when the seat is folded, the first connecting rod 13, the second connecting rod 14 and the third connecting rod 15 not only rotate relative to each other, but also can rotate relative to the first frame to be folded (as shown in Figure 12 , 15 ).

[0067] Preferably, a first blocking portion 115 protrudes from the first frame 11, and a second blocking portion 162 protrudes from the side of the armrest seat 161 facing the blocking portion 121; when the child seat is in the unfolded state, the first blocking portion 115 and the second blocking portion 162 are arranged at intervals, and one side of the first connecting rod is located between the first blocking portion 115 and the second blocking portion 162 and abuts against the first blocking portion 115 and the second blocking portion 162 (as shown in Figure 3 ). With such a setting, when the child seat is in the unfolded state, the first connecting rod 13 cannot rotate, so the second connecting rod 14 and the third connecting rod 15 cannot rotate either, thereby ensuring the stability and safety of the use of the child seat. When folding, as the second frame 12 rotates, the armrest seat 161 rotates together, so that the second blocking portion 162 disengages from the abutting block of the first connecting rod 13, and the first connecting rod 13 can rotate, so the second connecting rod 14 and the third connecting rod 15 can also rotate.

[0068] The first connecting rod 13, the second connecting rod 14 and the third connecting rod 15 are connected to both the left and right sides of the child seat 1. Preferably, the two sides of the third connecting rod 15 away from the first frame 11 are respectively connected to the left and right ends of a cross bar 151, so that the seat tube as a whole is U-shaped. Thus, when the child seat of the present invention is adjusted to the sleeping box state, the cross bar 151 can support the lower end of the sleeping box.

[0069] A seat locking mechanism for restricting relative rotation between the two is provided between the first frame 11 and the second frame 12. In this embodiment, the child seat 1 locking mechanism includes a card slot 116 provided on the side of the first frame 11 facing the second frame 12 (as Figure 8 shown), a locking member provided in the first frame 11, and a fourth elastic member (not shown in the figure) provided between the locking member and the second frame 12. Under the action of the fourth elastic member, one side of the locking member is snapped into the card slot 116, so that the first frame 11 and the second frame 12 cannot rotate relative to each other, and the seat cannot be folded. Preferably, the seat locking mechanism is provided between the corresponding sides of the left and right sides of the first frame 11 and the second frame 12. A seat unlocking mechanism for unlocking the seat locking mechanism is further provided on the second frame 12. The child seat 1 unlocking mechanism includes an unlocking assembly 122 provided on the second frame 12 and two steel wires, one ends of which are respectively connected to the unlocking assembly 122. The other ends of the two steel wires are respectively connected to the locking members on both sides. By operating the unlocking assembly 122, the two steel wires can be pulled, so as to drive the two locking members to move into the first frame 11 and disengage from the card slot 116, and the seat locking mechanism is unlocked. The first frame 11 and the second frame 12 can rotate relative to each other, and the seat can be folded.

[0070] In other embodiments, the child seat 1 locking mechanism and the seat unlocking mechanism can also be any other known and feasible structures, which are not the inventive points of the present invention, so they will not be elaborated here.

[0071] The present invention also discloses a baby stroller, which includes a collapsible vehicle frame 3 and the child seat 1. The child seat 1 is detachably connected and can be connected to the vehicle frame 3 in a front-back reversible manner through a mounting seat 2.

[0072] In this embodiment, the frame 3 includes two connected left and right side brackets 31, each side bracket 31 is provided with a matching seat 32, and the mounting seats 2 on both sides of the child seat 1 are configured to be detachable and reversibly connected to the matching seats 32 on the corresponding side. When the child seat is to be reversed, the mounting seats 2 on both sides of the child seat are removed from the matching seats 32 on both sides of the frame 3, and then after the child seat and the mounting seats 2 are reversed, the mounting seats 2 on both sides of the child seat are assembled to the matching seats 32 on the corresponding side of the frame 3.

[0073] The specific structure and folding method of the frame 3 (including the matching seat 32) can be any known and feasible structure, and the detachable connection and front-to-back reversible connection between the mounting seat 2 and the frame matching seat 32 can also be any known and feasible technology. Since it is not the invention point of the present utility model, it will not be described here.

[0074] When it is not necessary to fold the child seat 1 and the frame, but only to adjust the inclination angle of the child seat relative to the frame 3, the button 20 is pressed to push the gear 5 to move toward the first tooth groove 111. When the gear 5 moves to disengage the second tooth groove 21 on the mounting seat 2 and only engages with the first tooth groove 111, the locking mechanism is unlocked, and the child seat 1 as a whole can be rotated relative to the mounting seat 2. In this way, the child seat as a whole can be rotated to the required inclination angle. When the child seat is rotated to an angle where the first frame 11 and the second frame 12 are parallel to the ground, the seat cloth on the seat can be adjusted, so that the seat becomes a sleeping box. During the above operation, the linkage part remains stationary, so the child seat is not linked and folded, that is, the second frame 12 does not rotate relative to the first frame 11, so that the action member 63 is always suppressed by the blocking member on the second frame 12 and cannot move out of the accommodating cavity 113, so that the limit seat 611 and the limit pin 612 cannot move and disengage from the arc-shaped limit groove 22. During the rotation of the child seat as a whole relative to the mounting seat 2, the side of the limit pin 612 away from the action member 63 is always rotating and moving in the arc-shaped limit groove 22 of the mounting seat 2. When the limit pin 612 rotates and moves to either end of the arc-shaped limit groove 22, the child seat cannot continue to rotate in this direction. That is to say, under the premise of not being folded, the angle of rotation of the child seat as a whole relative to the frame 3 can only be within the travel range limited by the limit pin 612 and the arc-shaped limit groove 22. Therefore, during use, it can be ensured that the inclination angle of the entire seat relative to the mounting seat 2 (i.e., relative to the frame 3) is within a certain range, and the travel range limited by the limit pin 612 and the travel groove can be set according to relevant safety requirements, so that the inclination angle range is also within the safety range of relevant safety requirements, thereby ensuring the safety of the child seat in use, that is, ensuring the safety of the child in the child seat.

[0075] The connection of the seat cloth on the child seat 1 can be any well-known and feasible technology. The adjustment of the seat cloth in the two forms of the child seat and the sleeping box is also any well-known and feasible technology, and it is not the inventive point of the present utility model, so it will not be elaborated here.

[0076] When the child seat 1 is to be folded, regardless of whether the child seat 1 is forward or backward arranged relative to the vehicle frame 3, first unlock the seat locking mechanism, and then rotate the second frame 12 in the direction towards the first frame 11 (if the seat is forward arranged, that is, rotate the second frame 12 forward and downward; if the seat is backward arranged, that is, rotate the first frame 11 backward and downward). Through the cooperation of the driving hole 120 and the linkage part 41, the linkage 4 is driven to rotate. When the linkage 4 rotates, through the cooperation of the active inclined surface 42 thereon and the driven inclined surface 52 on the gear 5, the gear 5 is driven to move towards the inside of the first tooth groove 111. When the second frame 12 rotates to be close to and overlap with the first frame 11 (as Figure 15 shown), the child seat is folded. At this time, the gear 5 is completely disengaged from the second tooth groove 21 on the mounting seat 2 and only meshes with the first tooth groove 111, so that the locking mechanism is unlocked, and the whole child seat 1 can rotate relative to the mounting seat 2; during the rotation of the second frame 12, when the rotation reaches that the blocking part 121 completely disengages from the contact with the acting part 63 and no longer blocks the acting part 63, under the action of the second elastic member, the limiting member 61 moves in the direction away from the arc-shaped limiting groove 22. Because of the cooperation of the second inclined surface on the limiting seat 611 and the first inclined surface 630 on the acting part 63, the acting part 63 is driven to move in the direction outside the accommodating cavity 113. When the limiting pin 612 disengages from the arc-shaped limiting groove 22, the limiting mechanism is unlocked, and the folded child seat can rotate 360 degrees relative to the mounting seat. That is to say, regardless of whether the child seat 1 is forward or backward arranged relative to the vehicle frame 3, during the folding process of the child seat, the second frame 12 rotating relative to the first frame 11 can not only unlock the locking mechanism in a linkage manner, but also unlock the limiting mechanism in a linkage manner, so that the folding operation of the whole child seat of the present utility model is very simple; and the whole folded child seat 1 can rotate 360 degrees forward and backward relative to the mounting seat 2, that is, rotate 360 degrees forward and backward relative to the vehicle frame 3.

[0077] When the baby stroller of the present utility model is to be folded, first fold the baby seat 1 according to the above operation. After the folded baby seat 1 is rotated as a whole to an angular position where it will not interfere with the folding of the frame 3, then fold the frame 3. Specifically, if the frame 3 is set such that the folded baby seat 1 must be in the angular position of the front lower side, then, if the baby seat 1 was originally set forward, when it is folded, the second frame 12 originally rotates forward and downward to lean against the first frame 11 on the front lower side, that is, the whole of the seat after folding is in the angular position of the front lower side; if the seat was originally set backward, after it is folded, the whole is in the angular position of the rear lower side, but because the folded baby seat as a whole can rotate 360 degrees relative to the mounting seat, therefore, the baby seat as a whole can be rotated forward to an angular position where it is in the front lower side. Similarly, if the frame 3 is set such that the folded baby seat must be in the angular position of the rear lower side before folding the frame 3, the same principle as above is also used to operate the baby seat; if the frame 3 is set such that the folded baby seat must be in a certain other angular position, the same principle as above is also used to operate the baby seat.

[0078] As described above, because of the above settings, regardless of whether the baby seat 1 is set forward or backward, the folded baby seat 1 can be rotated to an angular position where it does not interfere with the folding of the frame 3. Therefore, the present utility model does not need to remove the baby seat from the frame 3, and regardless of whether the baby seat 1 is set forward or backward relative to the frame 3, the frame 3 can be folded. There is no need to, like a conventional baby stroller, must remove the baby seat from the frame 3 or must adjust the baby seat to the forward position or the backward position to fold the frame 3, thus making the overall folding operation of the baby stroller of the present utility model more convenient.

[0079] Those skilled in the art should understand that the orientation or positional relationship indicated by the above front, back, left, right, up, and down is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the embodiments of the present utility model 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 cannot be construed as a limitation to the present utility model; and when the vision changes, the orientation will change accordingly.

[0080] The above has described the embodiments of the present utility model in detail, but the content described is only the preferred embodiments of the present utility model and cannot be considered as used to limit the scope of implementation of the present utility model. All equivalent changes and improvements made according to the scope of the application of the present utility model should still fall within the scope covered by the patent of the present utility model.
