The support 1 includes a pivot base 12, and the rotary base 4 is connected to the upper side of the pivot base 12 in a relatively horizontal rotatable manner. The second locking device may be disposed between the pivot seat 12 and the rotating seat 4 or/and the first connecting member 5. Specifically, the lower side of the second locking member 91 is connected to the pivot base 12 in a manner of moving up and down relatively, and the second elastic member 92 is disposed between the second locking member 91 and the pivot base 12. In this embodiment, the pivot seat 12 is provided with an accommodating groove 121 with an upward opening, the lower side of the second locking element 91 is connected to the accommodating groove 121 in a manner of moving up and down relatively, the second elastic element 92 is a compression spring, the compression spring is disposed in the accommodating groove 121, the upper end of the compression spring abuts against the second locking element 91, and the lower end of the compression spring abuts against the bottom wall of the accommodating groove 121. So that the second locking member 91 always maintains the upward movement tendency under the action of the compression spring. When the upper side of the second locking member 91 extends into the second locking hole 93, the rotating base 4 and the pivoting base 12 cannot rotate horizontally relative to each other, so that the seat 2 and the frame 1 cannot rotate horizontally relative to each other, i.e. the seat 2 cannot be reversed back and forth relative to the frame 1.

The support 1 further comprises a moving member 13 which is connected to the pivot base 12 in a relatively vertically movable manner and extends vertically, and the rotating base 4 is sleeved outside the upper side of the moving member 13 in a relatively horizontally rotatable manner. Said second locking means can also be provided between said moving member 13 and the rotating seat 4 or/and the first connecting member 5. Specifically, the third locking hole is formed in the moving member 13, and when the locking portion 841 of the third driving member 84 is inserted into the third locking hole of the moving member 13, the first connecting member 5 and the rotary base 4 cannot horizontally rotate with respect to the moving member 13, so that the seat 2 cannot horizontally rotate with respect to the bracket 1.

The support 1 is configured to be convertible between a folded state and an unfolded state, and the support 1 further includes a front leg 14 having a rear end pivotally connected to the pivot base 12, a rear leg 15 having a front end pivotally connected to the pivot base 12, a front support member 16 having a rear end pivotally connected to the moving member 13, and a rear support member 17 having a front end pivotally connected to the moving member 13, wherein the front end of the front support member 16 is pivotally connected to the front leg 14, the rear end of the rear support member 17 is pivotally connected to the rear leg 15, and positions where the rear end of the front support member 16 and the front end of the rear support member 17 are pivotally connected to the moving member 13 are located at a lower side of the pivot base 12. With such an arrangement, when the moving member 13 moves upward relative to the pivot base 12, the rear end of the front support member 16 and the front end of the rear support member can be driven to move upward, so that the front leg 14, the rear leg 15, the front support member 16 and the rear support member 17 can be drawn together in the direction of the vertical extension of the moving member 13, and the support 1 can be folded like an umbrella.

The second locking hole is formed in the moving member 13, and when the locking portion 841 is engaged in the third locking hole of the moving member 13, the seat 2 cannot rotate horizontally relative to the bracket 1, and the moving member 13 cannot move up and down relative to the rotating base 4 or the pivot base 12, so that the bracket 1 cannot be folded. That is, when the locking portion 841 is engaged in the third locking hole of the moving member 13, the seat 2 and the bracket 1 are prevented from being horizontally rotated relative to each other, and the bracket 1 is also prevented from being folded. Similarly, through the above arrangement, the unlocking first locking device can not only unlock the locking device for limiting the horizontal rotation of the seat 2 relative to the support 1 in a linkage manner, but also unlock the locking device for limiting the folding of the support 1, namely, the operation of one unlocking first locking device can enable the driver 3 to rotate back and forth relative to the seat 2, further enable the seat 2 to rotate horizontally relative to the support 1, and enable the support 1 to be folded, thereby achieving multiple purposes.

In this embodiment, preferably, the lower end of a rotating cylinder 130 is horizontally and rotatably connected to the pivot base 12, the upper side of the rotating cylinder 130 extends into the rotating base 4, and the moving member 13 extends into the rotating cylinder 13; the drum 130 can be horizontally and rotatably connected with the pivot base 12 through a bearing, and when the seat 2 rotates relative to the frame 1, the rotating base 4 rotates relative to the frame 1 together with the drum 130. Thereby making the seat 2 rotate more smoothly with respect to the frame 1 and less prone to wear. A through hole is provided on the side wall of the drum 130 at a position corresponding to the locking portion 841, the locking portion 841 passes through the through hole and is inserted into the third locking hole, and the third driving member 84 is not disengaged from the locking portion 841 after unlocking. So that the rotary base 4 rotates together with the drum 130 relative to the support 1.

The front lower part of the front leg 14 is connected with a front wheel 141, and the rear lower part of the rear leg 15 is provided with a rear wheel 151.

The lower side of the seat 2 is connected with a connecting seat 21, the connecting seat 21 is connected to the upper side of the rotating seat 4, so that the purpose of connecting the seat 2 and the rotating seat 4 is achieved, and one side of the connecting seat 21 is pivoted with the rotating seat 4. The connection manner of the seat 2 and the connection seat 21 can adopt any known and feasible structure, and is not the invention point of the invention, so the description is omitted here.

Referring to fig. 21 to 23, the upper side of the moving member 13 passes through the rotating base 4 and is pivotally connected to the connecting base 21, the upper side of the moving member 13 and the rotating base 4 are pivotally connected to different positions of the connecting base 21, and the moving member 13 is further configured to horizontally rotate relative to the connecting base 21. With the arrangement, when the support 1 is not folded, the rotating seat 4, the connecting seat 21 and the seat 2 can horizontally rotate relative to the support 1, namely, the seat 2 can horizontally rotate relative to the support 1, so that the seat 2 is arranged in a forward and backward reversing manner relative to the support 1; when the frame 1 is folded, when the moving member 13 moves upward, the side of the connecting base 21 not pivoted with the rotating base 4 can be pushed upward and rotate toward the side pivoted with the connecting base 21, that is, the seat 2 can rotate together with the frame 1 to move close to each component of the frame 1, so that the whole folding operation of the stroller is simpler and more convenient.

In this embodiment, the moving member 13 is connected to the connecting seat 21 through a second linkage device, the second linkage device includes a pivot member 131 connected to the upper side of the moving member 13 in a relatively horizontal rotation manner, and a second linkage member 132 having one end pivotally connected to the pivot member 131, the other end of the second linkage member 132 is pivotally connected to the connecting seat 21, and the other end of the second linkage member 132 and the rotating seat 4 are pivotally connected to different positions of the connecting seat 21. With such an arrangement, when the moving member 13 moves upward, one side of the connecting seat 21 pivotally connected to the second linkage member 132 can be pushed upward by the moving member 13, so that the connecting seat 21 rotates about the pivot shaft pivotally connected to the rotating seat 4.

A T-shaped mating piece 133 is fixedly connected to the upper end of the moving piece 13, and a transverse part 1331 of the T-shaped mating piece 133 is positioned outside the upper end of the moving piece 13; the pivoting member 131 comprises a bottom member 1311 and a top member 1312 fixedly connected to one side of the bottom member 1311, wherein the bottom member 1311 is relatively horizontally and rotatably connected to the T-shaped mating member 133 or/and the moving member 13 and is located below the transverse portion 1331 of the T-shaped mating member 133, and one side of the top member 1312 is relatively horizontally and rotatably located above the transverse portion 1331 of the T-shaped mating member 133; the second linkage member 132 has one end pivotally connected to the bottom member 1311. With this arrangement, the pivot member 131 can rotate horizontally relative to the moving member 13 and will not fall upward, and when the moving member 13 moves upward, the moving member pushes the top member 1312 to move upward, i.e. the pivot member 131 is driven to move upward, so as to drive the other end of the pivot member pivoted to the second link member 132 to move upward, so as to rotate the connecting base 21 pivoted to the other end of the second link member 132 relative to the rotating base 4.

Because the present invention is configured as above, when only the front-back direction of the rider 3 relative to the seat 2 is adjusted, the first locking device can be unlocked by the first unlocking device or the second unlocking device, and after the first locking device is unlocked, the rider 3 can be rotated back and forth, and after the rider 3 is rotated to a position, the positioning member 711 is inserted into the first locking hole 37 at the corresponding position under the action of the first elastic member 72, so that the rider 3 is locked at the relative angular position. Although the second locking device and the third locking device are also unlocked in a linkage manner when the first locking device is unlocked, the moving member 13 cannot move upwards because of gravity when a child sits on the seat 2, so that the support 1 cannot be folded, and the safety of the child in the seat 2 cannot be influenced; further, if the horizontal rider 3, the first link 5, or the seat 2 is not rotated, the seat 2 is not rotated horizontally with respect to the bracket 1, and thus the seat 2 is not reversed with respect to the bracket 1. When the rider 3 is on the same side of the back of the seat 2, the child is seated in the seat 2 facing away from the parent of the stroller, and when the rider 3 is adjusted to the other side, the child is seated in the seat 2 facing the parent of the stroller.

When the front and back directions of the seat 2 are to be adjusted, assuming that the seat 2 is in a forward setting state (i.e., a state shown in fig. 1) relative to the bracket 1, at this time, the rider 3 and the seat 2 are positioned on the same side by back, when the front and back directions of the seat 2 are to be adjusted, the first locking device is unlocked by the first unlocking device or the second unlocking device, so that the rider 3 can rotate relative to the first connection, and at this time, the rider 3 can rotate forward to a vertical state; and because the second locking mechanism is unlocked by the linkage of the unlocking first locking device, at the moment, the rotating seat 4, the connecting seat 21, the seat 2 and the rider 3 can rotate relatively horizontally, and at the moment, the rider 3 can rotate horizontally, so that the rider 3, the first connecting piece 5, the rotating seat 4, the connecting seat 21 and the seat 2 can rotate horizontally relative to the bracket 1; similarly, although the second locking device is unlocked, the moving member 13 will not move upwards because of gravity when a child sits on the seat 2, so that the support 1 will not be folded, and the safety of the child in the seat 2 will not be affected; when the seat 2 is rotated 180 degrees to be arranged backwards relative to the bracket 1, under the reset action of the second elastic piece 92, the second locking piece 91 moves upwards and extends into the second locking hole 93 corresponding to the position, the second locking device is in a locking state, the rotating seat 4 cannot horizontally rotate relative to the bracket 1, namely, the seat 2 is locked in a state arranged backwards relative to the bracket 1 and cannot horizontally rotate relative to the bracket 1, and the rider 3 is still in a vertical state (as shown in 19); meanwhile, the upward movement of the second locking member 91 pushes the second unlocking member to move upward, so that the third driving member 84 moves back to the side of the rider 3 through the cooperation of the third driven inclined surface 941 and the third driving inclined surface 840, until the locking portion 841 on the side of the third driving member 84 is inserted into the corresponding third locking hole of the moving member 13, and the third locking device is also in a locking state; and upon such movement of the third driving member 84, the first link member 81 moves toward the rider 3, thereby pressing the first elastic member 72 by pushing the carrier 712; at this time, the rider 3 can be rotated backward, and when the rider rotates to a certain angle, under the restoring force of the first elastic member 72, one side of the positioning member 711 extends into the corresponding first locking hole, the first locking device is in a locked state, and the rider 3 is locked at the angle position (as shown in fig. 20), so that the forward and backward directions of the seat 2 and the locking of the rider 3 are achieved again. In this state, the child is a parent facing the stroller when seated in the seat 2. That is, regardless of the orientation of the seat 2 with respect to the frame 1, the rider 3 can be adjusted to be in the same orientation as the rear wheel 151 of the stroller, so that the traveling convenience of the stroller is not affected regardless of the structure of the frame 1.

Preferably, the first unlocking device and the second unlocking device are also set to be not driven when the first unlocking device is operated to unlock the first locking device; when the second unlocking means is operated to unlock the first locking means, the first unlocking means is not driven. That is to say, the first unlocking device and the second unlocking device do not interfere with each other, so that the function of the other unlocking device is prevented from being influenced by operating one unlocking device, and the first locking device can be unlocked by operating the first unlocking device or the second unlocking device at any time.

In this embodiment, a space capable of avoiding the first steel wire 310 is provided between the second unlocking device and the handle 3, and specifically, an avoiding groove (not shown) is provided on a side of the push handle 34 facing the first steel wire 310, so that the push handle 34 does not interfere with the first steel wire 310 when moving up and down; an avoiding groove 332 (as shown in fig. 9) is also formed at a lower side of the second driving member 33 toward the first wire 310, so that the second driving member 33 does not interfere with the first wire 310 even when moving up and down. Therefore, when the first unlocking device is operated, the second unlocking device cannot be driven, and similarly, when the second unlocking device is operated, the first unlocking device cannot be driven and does not interfere with each other.

The linkage member 333 is spaced apart from the first steel wire 310, and the avoidance groove 332 is provided on a side of the action member 334 facing the first steel wire 310.

In this embodiment, the rider 3 includes a rider tube 35 and a second connecting member 36 fixedly connected to a lower end of the rider tube 35, and the second accommodating space 30 is disposed in the second connecting member 36. So set up, be convenient for each relevant subassembly equipment. In other embodiments, the second accommodating space 30 may be formed at the lower side of an integral component.

The arrangement of the invention is that the orientation of the child sitting in the seat 2 and the parents of the stroller can be changed by only adjusting the front-back direction change of the handle 3, and the orientation of the child sitting in the seat 2 and the parents of the stroller can be changed by adjusting the front-back direction of the seat 2 and combining the rotation of the handle 3, namely, the adjustment modes are diversified, so that the function of adjusting the orientation of the child and the parents can be ensured more than a single adjustment mode.

In other operations, after the seat 2 is angularly adjusted, the handle 3 may be rotated forward, and when the handle is rotated to a certain angle, one side of the positioning member 711 may also extend into the corresponding first locking hole by the restoring force of the first elastic member 72, but only in this state, the handle 3 is located on the same side as the backrest, that is, on the front side with respect to the frame 1.

When the stroller of the present invention is to be folded, a child is firstly taken down from the seat 2, the first unlocking device or the second unlocking device unlocks the first locking device to unlock the third locking device in a linkage manner, then the handle 3 is rotated backward and downward, so that the positioning member 711 can not be inserted into the first locking hole, that is, the second locking device and the locking mechanism of the support 1 are all kept in an unlocked state, then the seat 4 and the connecting seat 21 are rotated upward and to one side relative to the pivot seat 12, the moving member 13 is driven by the second linkage device to move upward, so as to drive the front leg 14, the rear leg 15, the front support member 16 and the rear support member 17 to be folded in an umbrella shape, and the seat 2 can be rotated to one side of the folded support 1.

The first unlocking device and the second unlocking device are arranged at the same time, so that the first locking device can be unlocked in different modes, the situation that the first locking device cannot be unlocked due to the fact that one unlocking device is broken is avoided, and the arrangement is convenient to operate and more suitable for the operation habit of people. Specifically, when only the front-rear direction of the rider 3 is to be adjusted individually or the front-rear direction of the seat 2 is to be adjusted, it is more appropriate to unlock by operating the first unlocking means, and because the first operating member 31 is to be moved upward, it is relatively more appropriate to rotate the rider 3 forward after this operation; when the child stroller is folded, the second unlocking device is operated to unlock the stroller, and the handle 3 is rotated backwards and downwards after unlocking, and the handle 34 is required to move downwards relative to the handle 3 when the second unlocking device is operated to unlock the stroller, so that the operation of rotating the handle 3 backwards and downwards is more smooth.

In this embodiment, a handle 1313 is connected to the bottom part 1311 or/and the top part 1312, so that when the stroller of the present invention is folded, when the handle 3 is rotated backward and downward, and the handle 1313 is pulled upward, the moving member 13 is pulled to move upward, and by pushing the second linking member 132, the connecting seat 21 is rotated upward and toward the side pivoted with the rotating seat 4 to approach the folded frame 1, so that the frame 1 is folded, the seat 2 approaches each component of the frame 1 (as shown in fig. 24), and the backrest 22 approaches the seat 23, so that the stroller of the present invention is completely folded.
