In addition, as shown in fig. 5 to 7, a torsion spring 233 is further disposed at a hinge joint of the first hinge link 231 and the lower rear frame 22, one side of the torsion spring 233 extends upward along the first hinge link 231, and an end portion of the torsion spring 233 is provided with a buckle portion sleeved on the first hinge link 231. The upper frame can be folded by the first hinged connecting rod and the second hinged connecting rod, and the lower front frame is linked to be folded towards the lower rear frame, so that the folding operation is convenient and simple, and the folding operation is completed in one step. And the torsional springs are arranged on the first hinged connecting rod and the second hinged connecting rod, pressure is applied to the first hinged connecting rod and the second hinged connecting rod when the front wheel is unfolded through the torsional springs, after the front wheel is unfolded when the front wheel is folded, the first hinged connecting rod and the second hinged connecting rod are changed into a movable state from a fixed state, the first hinged connecting rod and the second hinged connecting rod are transferred to the lower front frame under the action of pressure pre-applied in the moment of conversion, and the front wheel of the lower front frame can rotate 180 degrees under the action of self weight when the front wheel is suspended, so that the front wheel can be kept in a standing state. More directly say, because the bassinet is in the expansion user state for a long time, so because inertia front wheel probably is compressed tightly for a long time at normal unsettled state and leads to the automatic rotation malfunctioning, at this moment need similar manual work to beat down the front wheel, let it resume the rotation state, and this scheme is through setting up this torsional spring, in the twinkling of an eye of unsettled state, the pressure transmission of torsional spring just plays the state of letting down the preceding frame shake to preceding frame department down, thereby it can overturn automatically to have guaranteed the front wheel, simple structure has played the key effect, make this scheme more reliable, and is practical.
Still further, the lower rear frame 22, the upper frame 1 and the lower front frame 21 are provided with a folding locking structure for limiting the rotation of the upper frame 1 and the lower front frame 21, the armrest frame 101 is provided with a linkage locking structure for limiting the rotation of the armrest frame 101 relative to the upper frame 1 and unlocking the folding locking structure after unlocking and rotating, and the armrest frame 101 is further provided with an unlocking structure for unlocking the linkage locking structure. The locking and unlocking operation of the frame is convenient.
Specifically, as shown in fig. 5 to 11, the specific structure of the folding locking structure is that a first hinge 11 is arranged at the lower end of the upper frame 1, a second hinge 12 is arranged at the upper end of the lower front frame 21, a third hinge 13 is arranged at the upper end of the lower rear frame, and both the first hinge 11 and the second hinge 12 can rotate relative to the third hinge 13; a first cavity is arranged on one side of the first hinge part 11, which is opposite to the second hinge part 12, and a second cavity is arranged on one side of the second hinge part 12, which is opposite to the first hinge part 11; the folding locking structure includes a locking member 81 disposed between the first cavity and the second cavity to limit the first hinge member 11 to rotate relative to the second hinge member 12, a rotating member 82 disposed in the first cavity and capable of pressing one side of the locking member 81 after rotation to move the locking member 81 toward the second cavity, and a return spring disposed between the locking member 81 and the second cavity. In the unfolded state, the locking member 81 is locked between the first cavity and the second cavity, which results in that the first hinge member 11 cannot rotate relative to the second hinge member 12, thereby playing a role of locking, and after the rotating member 82 is pulled to rotate, the rotating member moves towards the second hinge member 12 in the rotating process, thereby the locking member 81 on one side of the rotating member is pressed to move together, so that the locking member is separated from the first cavity and falls into the second cavity, thereby completing unlocking. Specifically, in this scheme, the periphery of latch fitting sets up the latch, set up on first cavity and second cavity internal perisporium and can realize kayser and unblock with latch complex draw-in groove, and rotate the piece and set up the inclined plane structure in one side and can realize rotating the effect of displacement about the in-process. In addition, the other side of the clamping and locking piece is provided with a return spring, so that automatic return can be realized.
Furthermore, a linkage steel rope connected with the rotating part 82 is arranged on the linkage locking structure, the unlocking structure is connected with the linkage locking structure through the unlocking steel rope, the linkage locking structure can be unlocked by pulling the unlocking steel rope through the unlocking structure, the armrest frame 101 can rotate relative to the upper frame 1 after unlocking, and the linkage steel rope is pulled during rotation to drive the rotating part 82 to rotate, so that the folding locking structure is unlocked. As shown in fig. 10 and 11, the lower end of the armrest frame 101 is provided with an armrest frame hinged seat 91, the upper end of the upper frame is provided with an upper hinged seat 92 hinged to the armrest frame hinged seat 91, the specific structure of the linkage locking structure is that the linkage locking structure comprises a second rotating member 93 arranged in the armrest frame hinged seat 91, a second locking member 94 arranged between the armrest frame hinged seat 91 and the upper hinged seat 92, and a third rotating member 95 arranged in the upper hinged seat 92 and rotating together with the armrest frame hinged seat 91, the locking and unlocking principle of the second locking member is similar to that of the folding locking structure, and the unlocking can be realized by pulling another steel rope. In the scheme, the first steel rope is pulled through the unlocking button 96 arranged on the armrest frame, the first steel rope pulls the second rotating piece to rotate to realize unlocking, after unlocking, the armrest frame rotates and is folded relative to the upper frame and drives the third rotating piece to rotate, and the third rotating piece is connected with the unlocking steel rope, so that the unlocking steel rope is pulled during rotation, and linkage unlocking of the folding and locking structure is realized.
In the scheme, as shown in fig. 6, fig. 12 and fig. 13, the specific structure of the seat is that the seat 3 comprises a seat frame 31 and a backrest frame 32 pivoted on the seat frame 31, two sides of the armrest frame 1 are provided with supporting members 4, two sides of the backrest frame 32 are provided with adapter members 5 which can be leaned on the supporting members 4 to prevent the backrest frame 32 from rotating backwards along the pivoting positions, and when the armrest frame 1 rotates backwards and folds relative to the lower frame 2, the supporting members 4 are separated from the adapter members 5, and the backrest frame 32 rotates backwards under the action of self gravity and folds together with the baby carriage. The invention provides a baby carriage capable of standing after being folded, compared with the mode of soft adjustment of the backrest of the existing baby carriage, the backrest of the baby carriage adopts the connection mode that an adapting piece is lapped on a bearing part on an armrest frame, so that the backrest frame is supported by the bearing part to keep the backrest inclined with the seat frame when the baby carriage is unfolded, and the baby carriage is convenient for the child to lean. When the frame is folded, the armrest frame rotates backwards to separate the bearing part from the adapting part, and the back rest frame loses support, so that the back rest frame also rotates backwards along the hinged part under the self gravity, and the back rest frame can be automatically folded together with the frame without being pressed by hands, so that the folding operation is simpler and more convenient. Similarly, when the frame is unfolded, the armrest frame is in contact with the adapting piece in the unfolding process, and the supporting piece and the adapting piece simultaneously drive the backrest frame to rotate and open together.
Furthermore, the supporting member 4 is provided with at least 2 blocking positions 41 for the adaptor member 5 to lean against, and the angle between the backrest frame 32 and the seat frame 31 can be changed when the supporting member 4 leans against different blocking positions 41. Most of the existing backrest adjusting methods adopt a soft adjusting method, such as the adjusting method disclosed in the patent "backrest stepless adjusting device applied to baby carriage seat" (application number CN201821472440.7), which adopts a method of contracting or loosening a binding belt to adjust the angle of the backrest. And because the tension of the binding belt on the two side rods in the adjusting process causes the two side rods to have the tendency of approaching or approaching each other, a cross rod cannot be arranged between the two side rods generally. In this scheme, adopt back frame card different screens on the supporting piece to carry out the hard mode of adjusting of angle modulation, need not to be taut to both sides pole, can accomplish angle modulation in the screens of difference through the card, certainly, current bassinet also has similar structure, but it sets up the screens mostly on the seat, also can accomplish angle modulation in the different screens of back frame card on the seat. However, the backrest frame can not be folded together when the frame is folded. In this scheme, the screens has set up 2, of course, can set up many adjustment gears and set up a plurality of screens according to the demand.
In addition, since the backrest frame of the present embodiment does not need to be tightened to the two side rods during adjustment, the backrest frame 32 includes a left side rod 321 and a right side rod 322 hinged to the seat frame 31 and an upper top rod 323 connected to the left side rod 321 and the right side rod 322, and the left side rod 321 and the right side rod 322 are provided with the adapter 5. Compared with the traditional soft adjustment, the horizontal upper ejector rod can be arranged between the two side rods, so that the headrest has a supporting function on the head position, and the headrest is more comfortable for children to use.
Furthermore, because the child leans against the backrest frame when in use and applies a backward pressure to the backrest frame, when the backrest frame is leaned in the blocking position, the backrest frame only needs to be limited to rotate backward in normal use. Of course, in order to maintain stability, in the present embodiment, the backrest frame 32 is fixed relative to the seat frame 31 when the adapter 5 is seated in the detent 41. Namely, when the backrest is clamped in the clamping position, the backrest frame is limited to rotate along the hinged position relative to the seat frame.
In addition, for convenience of use, the support member 4 can slide along the seat frame 31 relative to the adapter member 5, or the adapter member 5 can slide along the back frame 32 relative to the support member 4 to adjust different backrest angles by switching different positions. The adjusting of the angle of the backrest can be completed by separating the adapter from the original clamping position during sliding, rotating the backrest frame and then clamping the backrest frame into the clamping position of the other gear.
Specifically, the backrest frame 32 is further provided with an adjusting mechanism 6 which can pull the adaptor 5 to slide along the seat frame 31. Adopt the gliding mode of adapter 5 to adjust in this scheme, so its adjustment mechanism also sets up on the back frame for the structure is simpler, and it is more convenient to use.
More specifically, the adjusting mechanism 6 includes a connecting rod 61 connected to the two side adapters 5, an adjusting switch 62 disposed on the upper ejector 323, and a linkage 43 connected to the adjusting switch 62 and the connecting rod 61 and lockable by the adjusting switch, and the connecting rod 61 can be pulled by the linkage 43 to move the two side adapters 5 along the backrest frame 32. The linkage piece and the connecting rod simultaneously drive the adapting pieces on the two sides to synchronously move, and the device is simple in structure and convenient to operate. In the scheme, the linkage piece can adopt a binding band, and the adjusting switch adopts a connecting buckle for the binding band to pass through, so that after the switch is opened, the connecting rod on the other side can be pulled by pulling the binding band to adjust the length of the binding band, and the adjusting of the adapting piece is realized.
In addition, the adaptor 5 is provided with an elastic element 7 which is connected to the lower end of the adaptor and keeps downward tension when the adaptor is clamped in the clamping position. In this scheme, the elastic component is the spring for the adapter component remains throughout to push down the pressure in the screens, thereby prevents not hard up, can realize automatic re-setting moreover.
Still further, a rectangular hole is formed in the right side rod 322 along the length direction of the right side rod, and the adapter 5 is sleeved on the right side rod 322 and provided with a limit pin penetrating through the rectangular hole. When the adjusting device is used for limiting the adjusting angle, the adapter piece is prevented from being too large in sliding distance along the vertical sliding of the seat backrest, so that the adapter piece cannot be matched with a clamping position, and the tension is prevented from being too large, so that the spring on the lower side is too long to be stretched and lose efficacy. The simple structure is favorable for protecting the whole body and is more durable.
Besides, the adapter 5 on both sides is provided with a lug 51 which protrudes outwards and can be clamped in the clamping position 41, and the outer peripheral surface of the lug 51 is a circumferential surface or at least the lower side of the outer peripheral surface is provided with an arc surface. The arc-shaped surface or the circumferential surface is arranged to facilitate the clamping of the clamping plate in the clamping process to play a guiding role.
The invention provides a foldable baby carriage capable of standing, which takes the hinged part of an armrest frame and an upper frame as a first supporting point contacted with a placing surface and takes a front wheel or a rear wheel as a second supporting point after being folded, and the folded frame is in a standing state depending on the two supporting points, and the hinged part can not rotate, so that the baby carriage can keep standing stably and is not easy to displace. Therefore, the baby carriage can be easily placed in a standing mode after being folded, and other auxiliary objects are not needed to be used as supports, so that the baby carriage is convenient to transport and store.
The foregoing is illustrative of one or more embodiments provided in connection with the detailed description and is not intended to limit the practice of the invention to the particular forms disclosed. Similar or identical methods, structures and the like, or several technical deductions or substitutions on the premise of the conception of the invention, are considered to be the protection scope of the invention.
