When the support member 11 and the rear foot 12 are in the folded position shown in FIG. 10, and before they are fully deployed to the unfolded position shown in FIG. an intermediate state between switching), the rear foot 12 is separated from the support member 11, and then the rear foot 12 is separated from the push of the lower end of the push member 34, thereby providing enough space for the lower end of the push member 34 to allow the push member 34 and drive The member 32 slides along the length direction of the support member 11 in a direction protruding from the support member 11 (that is, in a direction close to the rear foot 12 ). The blocking member 31 can protrude from the supporting member 11 to block the stroke so as to block the pivoting of the push frame 20 . Moreover, it should be noted that, as long as the supporting member 11 is not fully supported by the rear foot 12 , that is, when the frame body 10 is not fully unfolded, the blocking member 31 is located in the blocking stroke and keeps blocking the pivoting of the push frame 20 .

Please refer to FIG. 9 and FIG. 11 , in this embodiment, the blocking mechanism 30 also includes an elastic member 35, the elastic member 35 abuts between the supporting member 11 and the pushing member 34, and the elastic member 35 constantly drives the pushing The member 34 drives the driving member 32 to slide along the length direction of the support member 11 in a direction protruding from the support member 11 (that is, in a direction close to the rear foot 12 ). When the frame body 10 is folded, the pushing member 34 can be driven by the elastic force of the elastic member 35 to automatically protrude from the support member 11 along the length direction of the support member 11 (that is, toward the direction closer to the support member 11). The direction of rear foot 12) slides to drive the driving part 32 to drive the stopper 31 to slide and protrude from the support part 11 to be in the blocking stroke, so as to realize the automatic reset of the stopper 31 and protrude out from the support part 11 to be in the blocking stroke without manual operation by the user The operation is more convenient and labor-saving. Specifically, in this embodiment, the elastic member 35 is preferably a spring, and the elastic member 35 is compressed and abuts between the support member 11 and the push member 34, so that the elastic member 35 can constantly drive the push member 34 to drive The member 32 slides along the length direction of the support member 11 toward the direction protruding from the support member 11 (that is, toward the direction close to the rear foot 12), and the structure is simpler and more compact. However, it is not limited to this.

With reference to Fig. 1 to Fig. 11, the working principle of the infant carrier 100 of this embodiment will be described in detail:

When the frame body 10 of the baby carrier 100 of this embodiment is in the collapsed state shown in FIG. The supporting member 11 and the pushing member 34 can be driven by the elastic force of the elastic member 35 to automatically protrude from the supporting member 11 along the length direction of the supporting member 11 (that is, toward the direction close to the rear foot 12) Sliding, thereby driving the driving member 32 to drive the stop member 31 to slide and protrude out of the support member 11 to be in the blocking stroke, so that the stop member 31 is blocked on the front side of the first side protrusion 22, so as to prevent the push frame 20 from pivoting away from the The forward use position prevents the push frame 20 from pivoting and toppling.

When it is necessary to expand the frame body 10 of the baby carrier 100 of this embodiment from the collapsed state shown in FIG. 10 to the unfolded position shown in FIG. The frame 20 drives the support member 11 to pivot synchronously, and at the same time, the operating armrest 14 pivots toward the front of the frame body 10 . Then the support member 11 is linked with the rear foot 12 to pivot and unfold relative to the armrest 14 through the connecting member 15 , and the support member 11 is linked with the front foot 13 to pivot and unfold relative to the armrest 14 through the seat tube 16 at the same time. Then the lower end of the pushing member 34 first pivots away from the rear foot 12 gradually, and then gradually pivots close to the rear foot 12. After the frame body 10 passes through the intermediate state shown in FIG. Push the lower end of the push member 34 by the rear foot 12 to drive the push member 34 to overcome the elastic force of the elastic member 35, and move toward the direction of retreating into the support member 11 along the length direction of the support member 11 (that is, toward the direction away from the rear foot 12 )slide.

Then, the driving member 32 drives the stopper 31 to gradually slide away from the hand push frame 20, but the stopper 31 is still located in the blocking stroke and keeps blocking the first side projection 22, so as to prevent the push stand 20 from being deployed. Pivot to dump in process. Until the lower end of the support 11 is supported by the rear foot 12, that is, the frame body 10 is fully deployed to the unfolded state shown in FIG. 11, the driving part 32 is finally driven to drive the stop part 31 to shrink to the supporting part 11 to prevent the push frame 20 from pivoting, and finally complete the unfolding operation of the frame body 10 of the infant carrier 100 of this embodiment.

When the frame body 10 is fully expanded to the unfolded state shown in FIG. 1 , the reversing sliding sleeve 21 can be operated to disengage from the lock with the forward positioning member 18, so that the push frame 20 can be used in the forward direction shown in FIG. 1 position and the rearward use position shown in FIG. 6 , and the reversing sliding sleeve 21 is locked to the forward positioning member 18 or the rearward positioning member 19 to realize the forward use position of the push frame 20 or locking positioning in the rearward use position.

When it is necessary to collapse the frame body 10 of the baby carrier 100 of this embodiment from the unfolded position shown in FIG. 1 to the folded state shown in FIG. In the forward use position shown, operate a release mechanism to release the frame body 10 . Then, the push frame 20 is operated to pivot toward the front of the frame body 10, the push frame 20 drives the support member 11 to pivot synchronously, and at the same time, the armrest 14 is operated to pivot toward the rear of the frame body 10, and the support member 11 is linked by the connecting member 15. The rear foot 12 pivots and folds relative to the armrest 14 , and the support member 11 simultaneously moves the front foot 13 to pivot and fold relative to the armrest 14 through the seat tube 16 . At the same time, the lower end of the support member 11 is gradually pivoted away from the rear foot 12, and the pushing member 34 is driven by the elastic force of the elastic member 35 to automatically protrude from the support member 11 along the length direction of the support member 11. (That is to say, slide towards the direction close to the rear foot 12) to drive the driving member 32 to drive the stopper 31 to slide and protrude from the support member 11 to be in the blocking stroke, so that the stopper 31 is blocked on the front side of the first side projection 22 , to prevent the push frame 20 from pivoting away from the forward use position, and prevent the push frame 20 from pivoting and falling.

Strictly speaking, as long as the lower end of the support member 11 breaks away from the rear foot 12, the elastic member 35 immediately drives the pushing member 34 toward the direction protruding from the support member 11 along the length direction of the support member 11 (that is, toward the direction close to the rear foot 12). ) slides, so that the stopper 31 also immediately protrudes out of the support member 11 and is located at the front side of the blocking stroke blocked by the first side bump 22, so as to prevent the push frame 20 from pivoting away from the forward use position and prevent the push frame 20 pivot to pour. And in the process of the frame body 10 being gradually closed, the stopper 31 continues to slide and protrude toward the push frame 20 until the pusher 34 breaks away from the conflict with the rear foot 12, so that the stopper 31 continues to block the push stand 20 pivot. After the frame body 10 passes through the intermediate state shown in FIG. 8, until it is completely collapsed to the collapsed state shown in FIG. The folding operation of the frame body 10 of the tool 100.

Please refer to FIG. 12 to FIG. 16 , showing a baby carrier 100 ′ of the second embodiment of the present invention. The structure of the baby carrier 100 ′ of this embodiment is basically the same as that of the baby carrier 100 of the first embodiment, the only difference is that : The blocking mechanism 30 ′ in this embodiment only includes a stop member 31 ′, a push member 34 ′ and an elastic member 35 ′, and the driving member 32 and the linkage rod 33 in the first embodiment are not provided. Moreover, the setting structure of the stopper 31 ′ on the support member 11 in this embodiment, and the connection structure between the stopper 31 ′ and the pusher 34 ′ are the same as those of the stopper 31 in the first embodiment. The arrangement structure on the support member 11 and the interlocking structure of the stop member 31 and the push member 34 are different. The arrangement structure of the stopper 31 ′ on the support member 11 and the connection structure of the stopper 31 ′ and the support member 11 in this embodiment will be described in detail below.

Please refer to Fig. 12 and Fig. 13. In this embodiment, the stopper 31' of the stopper mechanism 30' is slid on the support 11 along the length direction of the support 11, and the stopper 31' approaches the trolley The direction of 20 protrudes out of the support member 11, and the blocking stroke and avoidance stroke of the stopper 31′ that can be switched relative to the frame body 10 are distributed along the length direction of the support member 11, and the stopper 31′ can be reciprocally slid to switch between the blocking stroke and Avoid between trips.

When the frame body 10 is in the collapsed state, and before it is fully deployed to the unfolded state shown in FIG. ), thereby realizing locking the trolley frame 20 in the forward use position. In detail, the same as the first embodiment, in this embodiment, the push frame 20 also protrudes toward the direction of the support member 11 with a first side protrusion 22 ′, when the stopper 31 ′ is in the blocking stroke, The blocking member 31 ′ is blocked by the front side of the first side protrusion 22 ′, so as to prevent the push frame 20 from pivoting toward the front of the frame body 10 , thereby realizing the function of blocking the push frame 20 from pivoting. Moreover, in this embodiment, the support member 11 also protrudes toward the direction of the push frame 20 with a second side projection 111 ′, and the push frame 20 also protrudes toward the direction of the support member 11 with a third side projection 23 ', the second side projection 111' is also blocked by the rear side of the third side projection 23', which is also to prevent the push frame 20 from crossing the support member 11 and continuing to pivot backwards and dumping. The structure is reasonable, the use is more convenient and Safe and reliable.

When the frame body 10 is in the expanded state shown in FIGS. Switch between backward use positions.

Please refer to FIG. 13 and FIG. 16. Specifically, in this embodiment, the support 11 is provided with an elongated guide hole 113' arranged along the length direction of the support 11, and the stopper 31' is arranged along the length of the support 11. The direction slide is arranged in the elongated guide hole 113'. The blocking stroke is close to the lower end of the elongated guide hole 113 ′, and the avoidance stroke is close to the upper end of the elongated guide hole 113 ′, thereby realizing the reciprocating sliding switching structure of the stopper 31 ′ between the blocking stroke and the avoiding stroke, and the structure is simple and reasonable. Moreover, the elongated guide hole 113 ′ not only plays a role of guiding the sliding of the stopper 31 ′, but also limits the sliding range of the stopper 31 ′ along the length direction of the support member 11 .

Please refer to Fig. 13, Fig. 14 and Fig. 16, because the setting structure of the push piece 34' and the elastic piece 35' on the support piece 11 in this embodiment is the same as that of the push piece 34 and the elastic piece 35 in the first embodiment. The setting structure on the support member 11 is the same, so details will not be repeated here. In this embodiment, the push piece 34' is slidably arranged on the support piece 11 along the length direction of the support piece 11, the stopper 31' is fixedly connected to the push piece 34', and the push piece 34' can drive the stopper 31' reciprocating sliding switch between the blocking stroke and the avoidance stroke. In detail, in this embodiment, the blocking member 31 ′ is fixedly connected to the pushing member 34 ′ through two lugs 311 ′, and the structure is more firm and reliable, but it is not limited thereto. Therefore, during the folding process of the frame body 10, the push piece 34' slides along the length direction of the support piece 11 in the direction protruding from the support piece 11, and the push piece 34' drives the stop piece 31' to slide to the blocking stroke. , to block the pivoting of the push frame 20 (as shown in FIG. 15 and FIG. 16 ), thereby realizing locking the push frame 20 in the forward use position shown in FIG. 15 . When the frame body 10 is fully deployed to the unfolded state, the pusher 34 ′ slides along the length direction of the support 11 toward the direction of retreating into the support 11, and the pusher 34 ′ drives the stopper 31 ′ to slide to the avoidance stroke, To prevent the push frame 20 from pivoting (as shown in FIG. 12 and FIG. 13 ), the push frame 20 is allowed to switch between the forward use position and the rear use position relative to the frame body 10 .

When the support member 11 and the rear foot 12 are in the unfolded position shown in FIG. Slide until the lower end of the support member 11 is supported by the rear foot 12 (as shown in Figure 13 and Figure 14 ). Therefore, the pushing member 34 ′ drives the blocking member 31 ′ to slide along the length direction of the supporting member 11 toward the direction of retreating into the supporting member 11 , and finally realizes driving the blocking member 31 ′ to slide to the avoidance stroke to avoid the pivoting of the push frame 20 .

When the support member 11 and the rear foot 12 are in the retracted position, and before they are fully deployed to the deployed position (with reference to an intermediate state in which the frame body 10 is switched between the deployed state and the collapsed state shown in FIG. 15 and FIG. 16 ) , the rear foot 12 is detached from the support member 11, and the rear foot 12 is detached from the push on the lower end of the pusher 34 ′, thereby providing enough space for the lower end of the pusher 34 ′ to allow the pusher 34 ′ and the stopper 31 ′ Sliding along the length direction of the support member 11 toward the direction protruding from the support member 11 . The blocking member 31 ′ can slide to the avoidance stroke, so as to block the pivoting of the push frame 20 . Moreover, it should be noted that, as long as the supporting member 11 is not completely opposed to the rear foot 12 , that is, when the frame body 10 is not fully unfolded, the stopper 31 ′ is located in the blocking stroke, so as to keep blocking the pivoting of the push frame 20 .

With reference to Fig. 12 to Fig. 16, the working principle of the baby carrier 100' of this embodiment will be described in detail:

When the frame body 10 of the baby carrier 100 ′ of this embodiment is in the folded state, the push frame 20 is in the forward use position, and the support member 11 and the rear foot 12 are in the folded position, and the rear foot 12 is detached from the support member 11. Driven by the elastic force of the elastic member 35 ′, the pushing member 34 ′ can automatically slide along the length direction of the support member 11 toward the direction protruding from the support member 11 (that is, toward the direction close to the rear foot 12 ), Thereby driving the stopper 31 ′ to slide to the blocking stroke, so that the stopper 31 ′ is blocked on the front side of the first side projection 22 ′, so as to prevent the push frame 20 from pivoting away from the forward use position and prevent the push stand 20 pivot to pour.

When it is necessary to expand the frame body 10 of the baby carrier 100' of this embodiment from the folded state to the unfolded position shown in FIG. The member 11 pivots synchronously, and at the same time, the operating armrest 14 pivots toward the front of the frame body 10 . Then the support member 11 is linked with the rear foot 12 to pivot and unfold relative to the armrest 14 through the connecting member 15 , and the support member 11 is linked with the front foot 13 to pivot and unfold relative to the armrest 14 through the seat tube 16 at the same time. Then the lower end of the push piece 34 ′ first pivots away from the rear foot 12 gradually, and then gradually pivots close to the rear foot 12. After the frame body 10 passes through the intermediate state shown in FIG. , and the rear foot 12 pushes the lower end of the push piece 34 ′ to drive the push piece 34 ′ to overcome the elastic force of the elastic piece 35 ′, and drives the stop piece 31 ′ to retreat into the support piece 11 along the length direction of the support piece 11 direction to slide gradually. Before the frame body 10 is fully expanded to the expanded state shown in FIG. 12 , the stopper 31 ′ is still located in the blocking stroke, so as to keep blocking the first side projection 22 ′ and prevent the push frame 20 from pivoting and falling during the unfolding process. . Until the lower end of the supporting part 11 is supported by the rear foot 12, that is, the frame body 10 is fully deployed to the unfolded state shown in Figure 12, and when the supporting part 11 and the rear foot 12 are fully deployed to the deployed position, the pusher 34' is completely retracted and hidden In the support member 11 (as shown in FIG. 13 and FIG. 14 ), the stopper 31 ′ is driven to slide to the avoidance stroke, so as to avoid the pivoting of the push frame 20 .

When the frame body 10 is fully expanded to the unfolded state shown in FIG. 12 , the operating principle of the push frame 20 pivotally switching between the forward use position and the rear use position is the same as that of the push frame 20 in the first embodiment. The operating principle of the pivotal switching between the forward use position and the rear use position is the same, so details will not be repeated here.

When the frame body 10 of the baby carrier 100' of this embodiment needs to be folded from the unfolded position shown in FIG. In the use position, operate a release mechanism to release the lock of the frame body 10 . Then, the push frame 20 is operated to pivot toward the front of the frame body 10, the push frame 20 drives the support member 11 to pivot synchronously, and at the same time, the armrest 14 is operated to pivot toward the rear of the frame body 10, and the support member 11 is linked by the connecting member 15. The rear foot 12 pivots and folds relative to the armrest 14 , and the support member 11 simultaneously moves the front foot 13 to pivot and fold relative to the armrest 14 through the seat tube 16 . At the same time, the lower end of the support member 11 is gradually pivoted away from the rear foot 12, and the pushing member 34′ is driven by the elastic force of the elastic member 35′ to automatically protrude from the support member 11 along the length direction of the support member 11. direction (that is, the direction close to the rear foot 12) to drive the stopper 31' to slide to the blocking stroke, so that the stopper 31' is blocked on the front side of the first side protrusion 22' to block the hand push The frame 20 pivots out of the forward use position, preventing the push frame 20 from pivoting and tipping over.

To be more specific, as long as the lower end of the support member 11 is separated from the rear foot 12, the elastic member 35′ immediately drives the push member 34′ to slide along the length direction of the support member 11 in the direction protruding from the support member 11, so that the stop member 31′ It also immediately slides into the blocking stroke, and is blocked on the front side of the first side projection 22 ′ to block the pivoting of the push frame 20 from the forward use position, preventing the push frame 20 from pivoting and toppling over. And in the process of gradually retracting the frame body 10 , the stopper 31 ′ continues to be located in the blocking stroke, so that the stopper 31 ′ continues to keep blocking the pivoting of the push frame 20 . After the frame body 10 passes through the intermediate state shown in FIG. 15 , it continues to be folded to the fully folded state. At this time, the support member 11 and the rear legs 12 are completely folded to the folded position, and the baby carrier 100' of this embodiment is completed. The folding operation of the frame body 10.

Since the push frame 20 of the baby carrier 100, 100' of the present invention is pivotally connected to the frame body 10, the stop mechanism 30, 30' is movable on the frame body 10, and when the frame body 10 is in the retracted state, the stop The mechanism 30, 30' locks the pivoting position of the push frame 20, so as to prevent the push frame 20 from falling down on the ground, or falling to a wrong direction, so that the push frame 20 is in a wrong position. Furthermore, when the frame body 10 is in the folded state, the push frame 20 will not topple over, and the operation to ensure that the frame body 10 is unfolded to the unfolded state can be carried out smoothly, preventing user's wrong operation, making the operation more convenient, and greatly facilitating the user's life. Use; when the frame body 10 is in the unfolded state, the stop mechanism 30, 30' avoids the pivoting of the push frame 20 relative to the frame body 10, so that the user can adjust the position of the push frame 20 so as not to affect the user's hand push frame 20 pivot adjustment operations to meet the needs of users. Moreover, the infant carrier 100, 100' of the present invention also has the advantage of a simple and reasonable structure.
