Description

Technical Field

[0001] The present invention relates to the technical field of baby carriages, and particularly to an unlocking structure for a baby carriage. Background Art

[0002] Existing baby carriages generally include a frame having a folded state and an unfolded state, and a locking mechanism for locking the frame in the unfolded state; in addition, an unlocking mechanism is also required to unlock the locking mechanism to allow the baby carriage to be folded and rotated. In the prior art, most of them set the unlocking mechanism at the top of the push handle and connect it to the locking member in the locking mechanism through a traction cable. When the unlocking mechanism is operated to tension the traction cable, the locking member can be moved to unlock the locking mechanism.

[0003] However, due to the increasingly rich functions of existing baby carriages, multiple locking mechanisms are often set, so the number of unlocking components will also increase accordingly. This not only makes the operation inconvenient during use, but also makes the overall structure of the vehicle complex, with a high cost, and affects the overall aesthetics. Summary of the Invention

[0004] The object of the present invention is to provide an unlocking structure for a baby carriage, in which the first operating member cooperates with the first driving member or the second driving member correspondingly through the displacement of the second operating member, so as to drive the first unlocking linkage member or the second unlocking linkage member to unlock different locking mechanisms. The overall structure is simple, the cost is low, and the conversion operation is very convenient.

[0005] The technical solution of the present invention is: an unlocking structure for a baby carriage, which is used to unlock the first locking mechanism and the second locking mechanism of the baby carriage. The unlocking structure includes a first operating member that can move along a first direction, a second operating member arranged on the first operating member and capable of moving along a second direction, a first unlocking linkage member and a second unlocking linkage member respectively connected to the first locking mechanism and the second locking mechanism, and a first driving member and a second driving member for driving the first unlocking linkage member and the second unlocking linkage member to perform unlocking movement. The second operating member cooperates with the first driving member or the second driving member correspondingly through displacement.

[0006] Further, the unlocking structure includes a mounting seat that is relatively fixed to the baby carriage, and the mounting seat has a through hole for the first driving member and the second driving member to pass through;

[0007] The first unlocking linkage member includes a first sliding member that can slide relative to the mounting seat and a first traction cable connected between the first sliding member and the first locking mechanism; a first spring is arranged between the first driving member and the mounting seat, and the inner end of the first driving member is in inclined surface cooperation with the first sliding member.

[0008] The second unlocking linkage includes a second sliding member slidable relative to the mounting base and a second towing cable connected between the second sliding member and the second locking mechanism; a second spring is provided between the second driving member and the mounting base, and the inner end of the second driving member is in inclined surface cooperation with the second sliding member.

[0009] Further, in order to minimize the overall volume as much as possible, the first unlocking linkage and the second unlocking linkage, the first driving member and the second driving member are arranged symmetrically in parallel up and down; the outer ends of the first driving member and the second driving member respectively have a first avoidance groove and a second avoidance groove corresponding to the second operating member, and the first avoidance groove and the second avoidance groove are arranged staggeredly left and right.

[0010] Further, a housing is provided on one side of the mounting base close to the through hole. The first operating member is a button member, which is telescopically installed at the button hole of the housing. A sliding groove is provided at the exposed end of the first operating member. A sliding button slidably matched with the sliding groove is connected to the outer end of the second operating member, and a third spring is provided between the second operating member and the first operating member. In the figure of this embodiment, the first operating member slides telescopically back and forth relative to the mounting base, the second operating member slides left and right relative to the first operating member, and a convex block is formed at the inner end of the second operating member, and the convex block can slide back and forth in the first avoidance groove or the second avoidance groove.

[0011] Further, in order to increase the stability during the unlocking operation, there are two convex blocks, which are symmetrically arranged left and right at the inner end of the second operating member; the first avoidance groove and the second avoidance groove are respectively two corresponding to the two convex blocks.

[0012] Further, in order to facilitate the pushing of the second operating member, a protrusion for easy pushing is formed on the outer side surface of the sliding button.

[0013] Further, since the locking mechanisms of baby strollers are often arranged symmetrically left and right, in order to facilitate the simultaneous control of the locking mechanisms on both sides of the frame, the first sliding member and the second sliding member respectively have two and are symmetrically arranged left and right, and they are respectively slidably matched with the mounting base in the left and right directions; the left and right sides of the inner ends of the first driving member and the second driving member respectively have second guiding inclined surfaces matched with the first guiding inclined surfaces of the first sliding member and the second sliding member on both sides.

[0014] Further, the mounting base is arranged on the push rod of the baby stroller. The push rod is a hollow rod member, and an opening communicating with its inner cavity is provided on the push rod, and the mounting base is fixedly arranged in the opening.

[0015] For the convenience of installing the first unlocking linkage and the second unlocking linkage, the mounting base includes a base body and a cover plate. The through hole is formed on the cover plate. The first unlocking linkage and the second unlocking linkage are installed in the base body, and the base body is provided with through holes for the first traction cable and the second traction cable to pass through.

[0016] The advantages of the present invention are as follows: In the mounting base of the present invention, there are provided a first unlocking linkage and a second unlocking linkage respectively connected to the first locking mechanism and the second locking mechanism. And a second operating member slidable relative to the first operating member is provided on the first operating member. The second operating member is correspondingly matched with the first driving member or the second driving member through sliding displacement. When the first operating member is pressed, the second operating member drives the first unlocking linkage or the second unlocking linkage to move through the correspondingly matched first driving member or second driving member, so as to release the locking of the corresponding first locking mechanism or second locking mechanism. The overall structure of the present invention is simple, the cost is low, and the conversion operation is very convenient. Unlocking of different locking mechanisms can be achieved with one hand.

It should be understood that these embodiments are for illustrating the present invention and not for limiting the scope of the present invention. The implementation conditions adopted in the embodiments can be further adjusted according to specific conditions, and the implementation conditions not specified are usually those in conventional experiments.

[0036] As Figures 1 to 4 shown, an unlocking structure of a baby stroller is used to unlock a first locking mechanism and a second locking mechanism of the baby stroller. The unlocking structure includes a mounting base 7 fixedly relative to the baby stroller, a first operating member 1 movable relative to the mounting base 7 along a first direction (front-back direction), a second operating member 2 disposed on the first operating member 1 and movable along a second direction (left-right direction), a first unlocking linkage member 3 and a second unlocking linkage member 4 respectively connected to the first locking mechanism and the second locking mechanism, and a first driving member 5 and a second driving member 6 for driving the first unlocking linkage member 3 and the second unlocking linkage member 4 to perform an unlocking movement. The second operating member 2 is correspondingly matched with the first driving member 5 or the second driving member 6 through displacement.

[0037] In the figure of this embodiment, the first unlocking linkage member 3 and the second unlocking linkage member 4 are installed in the mounting base 7, and the mounting base 7 has a through hole 7-1 for the first driving member 5 and the second driving member 6 to pass through. The first operating member 1 and the second operating member 2 are installed on the front side of the mounting base 7.

[0038] In this embodiment, the specific structures and installation methods of the first unlocking linkage 3 and the first driving member 5 are as follows: The first unlocking linkage 3 includes a first sliding member 3-1 that can slide relative to the mounting base 7 and a first towing cable 3-2 connected between the first sliding member 3-1 and the first locking mechanism; a first spring 8 is provided between the first driving member 5 and the mounting base 7, and the inner end of the first driving member 5 is in inclined surface cooperation with the first sliding member 3-1.

[0039] In this embodiment, the specific structures and installation methods of the second unlocking linkage 4 and the second driving member 6 are as follows: The second unlocking linkage 4 includes a second sliding member 4-1 that can slide relative to the mounting base 7 and a second towing cable 4-2 connected between the second sliding member 4-1 and the second locking mechanism; a second spring 9 is provided between the second driving member 6 and the mounting base 7, and the inner end of the second driving member 6 is in inclined surface cooperation with the second sliding member 4-1.

[0040] In order to minimize the volume of the overall structure as much as possible, the first unlocking linkage 3 and the second unlocking linkage 4, the first driving member 5 and the second driving member 6 are arranged symmetrically in parallel up and down; the outer ends of the first driving member 5 and the second driving member 6 respectively have a first avoidance groove 5-1 and a second avoidance groove 6-1 corresponding to the second operating member 2, and the above-mentioned first avoidance groove 5-1 and second avoidance groove 6-1 are arranged staggeredly left and right.

[0041] In this embodiment, the specific installation structures of the first operating member 1 and the second operating member 2 are as follows: A housing 10 is covered on one side of the mounting base 7 close to the through hole 7-1. The first operating member 1 is a button member, which is telescopically installed at the button hole 10-1 of the housing 10. A sliding groove 1-1 is provided at the exposed end of the first operating member 1. A sliding button 2-1 slidably matched with the sliding groove 1-1 is connected to the outer end of the second operating member 2. A third spring 11 is provided between the second operating member 2 and the first operating member 1. In the figure of this embodiment, the first operating member 1 moves back and forth relative to the mounting base 7, the second operating member 2 slides left and right relative to the first operating member 1, and a convex block 2-2 is formed at the inner end of the second operating member 2, and the convex block 2-2 can slide back and forth in the first avoidance groove 5-1 or the second avoidance groove 6-1.

[0042] In order to increase the stability during the unlocking operation, there are two convex blocks 2-2, which are arranged symmetrically left and right at the inner end of the second operating member 2; the first avoidance groove 5-1 and the second avoidance groove 6-1 are respectively two corresponding to the above two convex blocks 2-2.

[0043] In order to facilitate the pushing of the second operating member 2, a protrusion 2-1-1 for easy pushing is formed on the outer side surface of the sliding button 2-1.

[0044] Since the locking mechanisms of baby strollers are often arranged symmetrically on the left and right, to facilitate the simultaneous control of the locking mechanisms on both sides of the stroller frame, the mounting seat 7 is provided on the push handle bar 12 of the baby stroller. The first sliding members 3-1 and the second sliding members 4-1 each have two and are arranged symmetrically on the left and right. They are respectively slidably engaged with the mounting seat 7 in the left-right direction. The left and right sides of the inner ends of the first driving member 5 and the second driving member 6 respectively have second guiding inclined surfaces that cooperate with the first guiding inclined surfaces 3-1-1 and 4-1-1 of the first sliding members 3-1 and the second sliding members 4-1 on both sides. Among them, the push handle bar 12 is a hollow rod member, and an opening 12-1 communicating with its inner cavity is formed on the push handle bar 12, and the mounting seat 7 is fixedly arranged in the opening 12-1.

[0045] To facilitate the installation of the first unlocking linkage member 3 and the second unlocking linkage member 4, the mounting seat 7 includes a seat body 7-2 and a cover plate 7-3. The through hole 7-1 is formed on the cover plate 7-3. The first unlocking linkage member 3 and the second unlocking linkage member 4 are installed in the seat body 7-2, and the seat body 7-2 has through holes 7-4 for the first towing cable 3-2 and the second towing cable 4-2 to pass through.

[0046] The working principle of the present invention is as follows:

[0047] When the second operating member 2 is in the first working position, the convex block 2-2 of the second operating member 2 cooperates with the outer end face of the first driving member 5, and the convex block 2-2 is aligned with the second avoiding groove 6-1 of the second driving member 6. At this time, when the first operating member 1 is pressed, the first operating member 1 moves along the first direction (front-back direction). The first operating member 1 drives the first driving member 5 to move inward through the second operating member 2 and drives the first sliding member 3-1 to slide and tighten the first towing cable 3-2, thereby unlocking the first locking mechanism. At the same time, the convex block 2-2 of the second operating member 2 that moves inward moves in the second avoiding groove 6-1 of the second driving member 6 (front-back direction), and the second driving member 6 remains stationary, and the corresponding second locking mechanism remains locked.

[0048] When the second operating member 2 moves along the second direction (left-right direction) to the second working position, the convex block 2-2 of the second operating member 2 cooperates with the outer end face of the second driving member 6, and the convex block 2-2 is aligned with the first avoiding groove 5-1 of the first driving member 5. At this time, when the first operating member 1 is pressed, the first operating member 1 moves along the first direction (front-back direction). The first operating member 1 drives the second driving member 6 to move inward through the second operating member 2 and drives the second sliding member 4-1 to slide and tighten the second towing cable 4-2, thereby unlocking the second locking mechanism. At the same time, the convex block 2-2 of the second operating member 2 that moves inward moves in the first avoiding groove 5-1 of the first driving member 5 (front-back direction), and the first driving member 5 remains stationary, and the corresponding first locking mechanism remains locked.

[0049] The mounting base 2 of the present invention is provided with a first unlocking linkage 3 and a second unlocking linkage 4 which are respectively connected to the first locking mechanism and the second locking mechanism. The first operating member 1 is provided with a second operating member 6 which can slide relative to it. The second operating member 6 is correspondingly matched with the first driving member 5 or the second driving member 6 through sliding displacement. When the first operating member 1 is pressed, the second operating member 2 drives the first unlocking linkage 3 or the second unlocking linkage 4 to move through the correspondingly matched first driving member 5 or the second driving member 6, so as to release the locking of the corresponding first locking mechanism or the second locking mechanism. The overall structure of the present invention is simple, the cost is low, and the conversion operation is very convenient. The unlocking of different locking mechanisms can be realized with one hand.

[0050] The above are only specific application examples of the present invention, which do not constitute any limitation to the protection scope of the present invention. In addition to the above embodiments, the present invention may also have other embodiments. Any technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection required by the present invention.
