Description

[Technical field]

[0001] The present invention relates to a baby product, and more particularly to an unlocking device and a stroller equipped with the unlocking device. [Background technology]

[0002] Strollers are means of transportation designed to provide convenience for infants' outdoor activities, and have been widely used for a long time. Currently, some strollers include a frame, a frame folding mechanism, front wheels, rear wheels, and a wheel rotation orientation mechanism. The frame folding mechanism is configured to fold the frame. In this way, when the stroller is not in use, the stroller can be folded into a smaller volume for easy carrying and storage. The wheel rotation orientation mechanism is configured to lock and unlock the rotatable rear wheels. The wheel rotation orientation mechanism unlocks the rear wheels so that the rear wheels can rotate freely. When inverting, the rear wheels can rotate at a certain angle to facilitate changing the orientation of the stroller. After changing the orientation, the wheel rotation orientation mechanism can be used to lock the rear wheels and reposition the rear wheels to move forward. However, the above-mentioned mechanism takes up more space in the stroller, the operation is very inconvenient, and the stroller looks bad, which may reduce consumers' purchase intention. Summary of the Invention

[0003] SUMMARY OF THE DISCLOSURE In order to solve the above-mentioned problems, the present invention provides an unlocking device and a stroller equipped with the unlocking device.

[0004] According to an embodiment of the present invention, an unlocking device includes at least one operating member, a first unlocking module, and a second unlocking module. The at least one operating member is movably disposed on a frame, and the frame includes a first locking mechanism and a second locking mechanism. The first unlocking module is movably disposed on the frame and connected to the first locking mechanism. The second unlocking module is movably disposed on the frame and connected to the second locking mechanism. The at least one operating member is moved to drive and move the first unlocking module to unlock the first locking mechanism or drive and move the second unlocking module to unlock the second locking mechanism.

[0005] In another embodiment, the unlocking device may further include a selection member movably disposed on the frame. The selection member moves between a first position and a second position relative to the frame. When the selection member is disposed in the first position, the at least one operating member drives and moves the first unlocking module to slide to unlock the first locking mechanism. When the selection member is disposed in the second position, the at least one operating member drives and moves the second unlocking module to slide to unlock the second locking mechanism.

[0006] In another embodiment, the at least one operating member may include a first operating member and a second operating member, the first operating member driving and moving the first unlocking module to slide to unlock the first locking mechanism, and the second operating member driving and moving the second unlocking module to slide to unlock the second locking mechanism.

[0007] In another embodiment, the unlocking device may further include a retention mechanism disposed on the at least one operating member. The retention mechanism retains the at least one operating member in the unlocked position when the at least one operating member slides to unlock one of the first locking mechanism and the second locking mechanism. The retention mechanism releases the at least one operating member when the at least one operating member is actuated from the unlocked position.

[0008] According to an embodiment of the present invention, a stroller includes a frame, a wheel socket, a first locking mechanism, a second locking mechanism, and the aforementioned unlocking device. The wheel socket is rotatably disposed on a leg of the frame. The first locking mechanism is disposed on the frame and configured to fold the frame. The second locking mechanism is disposed on the frame and configured to lock the wheel socket. The unlocking device is configured to unlock the first locking mechanism and the second locking mechanism.

[0009] As described above, the present invention uses at least one operating member to drive and move the first unlocking module to unlock the first locking mechanism or drive and move the second unlocking module to unlock the second locking mechanism. In an embodiment, the selection member may be movably disposed on the frame and may be movable between a first position and a second position relative to the frame. When the selection member is disposed in the first position, the first locking mechanism corresponds to the operating member such that the operating member can slide to drive and move the first unlocking module to unlock the first locking mechanism. When the selection member is disposed in the second position, the second locking mechanism corresponds to the operating member such that the operating member can slide to drive and move the second unlocking module to unlock the second locking mechanism. Thus, the present invention does not need to dispose two independent unlocking devices to unlock the first and second locking mechanisms. That is, the present invention can unlock two different locking mechanisms using one single unlocking device. Therefore, the manufacturing cost is reduced, the unlocking device of the present invention occupies less space in the stroller, and is easy and convenient to operate.

[0010] In another embodiment, the at least one operating member may include a first operating member and a second operating member configured to unlock the first locking mechanism and the second locking mechanism, respectively. In other words, the present invention may use two operating members to unlock two different locking mechanisms.

[0011] In another embodiment, the present invention may use a retaining mechanism to retain the operating member in an unlocked position when the operating member slides to unlock the first locking mechanism and the second locking mechanism. Thus, the first locking mechanism and the second locking mechanism can be retained in an unlocked state until the operating member is actuated from the unlocked position. For example, the second locking mechanism may be a wheel rotation orientation mechanism, and the retaining mechanism may retain the operating member in the unlocked position when the operating member slides to unlock the second locking mechanism. When the user presses the operating member to unlock the wheel rotation orientation mechanism, the wheel rotation orientation mechanism is retained in the unlocked position so that the wheels can still rotate freely even if the user releases the operating member. Furthermore, when the operating member is actuated from the unlocked position, the retaining mechanism allows the operating member to slide to lock the wheel rotation orientation mechanism and then release the operating member so that the wheels are locked.

[0012] These and other objectives of the present invention will no doubt become obvious to those of ordinary skill in the art after reading the following detailed description of the preferred embodiment that is illustrated in the various figures and drawings. [Brief description of the drawings]

[0041] 1 to 3, a stroller 100 of the present invention includes a frame 2, a wheel socket 3, a first locking mechanism 4, a second locking mechanism 5, and an unlocking device 1. In this embodiment, the first locking mechanism 4 may be, but is not limited to, a frame folding mechanism, and the second locking mechanism 5 may be, but is not limited to, a wheel rotation orientation mechanism. The frame 2 includes a handle 21, a front leg 22, and a rear leg 23, where the front leg 22 and the rear leg 23 are legs of the frame 2, and each wheel socket includes a wheel. The first locking mechanism 4 is disposed on the frame 2 and configured to fold the frame 2, and the first locking mechanism 4 is well known to those skilled in the art. In general, the first locking mechanism 4 may include a wire and a locking member. One end of the wire is connected to the locking member, and the locking member is engaged between the handle 21 and the rear leg 23 of the frame 2. When the other end of the wire is pulled, the wire drives the locking member out of engagement, unlocking the frame 2 so that the frame 2 can be folded. The first locking mechanism 4 is well known to those skilled in the art, so the figures only illustrate the wire of the first locking mechanism 4.

[0042] In an exemplary embodiment, the first locking mechanism 4 and the second locking mechanism 5 may be, but are not limited to, one of the locking mechanisms of handle conversion, wheel braking, handle angle adjustment, frame folding and wheel rocking lock, but their functions do not overlap with each other.

[0043] 1 and 8, the wheel socket 3 is rotatably disposed on the rear leg 23 through the central shaft 32 so that the wheel socket 3 can drive the wheel to rotate around the central shaft 32. The second locking mechanism 5 is disposed on the frame 2 and configured to lock the wheel socket 3. The second locking mechanism 5 includes a link mechanism member 51 and two positioning assemblies 52 connected to the link mechanism member 51. The positioning assembly 52 includes a first drag member 521, a second drag member 522, a positioning member, and a return member 524. The wheel socket 3 has a positioning portion, which may be a positioning hole 31. The positioning member may be a positioning pillar 523 configured to cooperate with the positioning hole 31. The positioning pillar 523 may be telescopically disposed in the positioning hole 31. The link mechanism member 51 is slidably disposed on the frame 2. An end of the first drag member 521 is connected to the link mechanism member 51, and another end of the first drag member 521 is connected to the positioning member. The positioning member is movably arranged on the leg of the frame 2, and can be connected to the positioning part, or can be separated from the positioning part. The return member 524 provides an elastic force to push the positioning member toward the positioning part. The second drag member 522 is connected between the second locking module 14 and the link mechanism member 51. When the second drag member 522 is pulled, the second drag member 522 pulls the link mechanism member 51 to slide relative to the frame 2 to drive the two first drag members 521 to pull the two positioning posts 523, so that the two positioning posts 523 retract into the rear leg 23 and compress the return member 524 (e.g., a spring). At this time, the two positioning posts 523 are ejected from the positioning holes 31 of the wheel socket 3 to unlock the wheel socket 3. As a result, the wheel socket 3 can rotate around the central shaft 32.

[0044] The unlocking device 1 is configured to unlock the first locking mechanism 4 and the second locking mechanism 5. Referring to FIG. 2 and FIG. 3, the unlocking device 1 of the present invention includes at least one operating member 11, a selection member 12, a first unlocking module 13, and a second unlocking module 14. In this embodiment, the unlocking device 1 includes, but is not limited to, one operating member 11. The operating member 11 is movably arranged on the frame 2. The selection member 12 is movably arranged on the frame 2. The sliding direction of the selection member 12 may intersect with the sliding direction of the operating member 11. The first unlocking module 13 is movably arranged on the frame 2 and connected to the first locking mechanism 4. The second unlocking module 14 is movably arranged on the frame 2 and connected to the second locking mechanism 5. The selection member 12 can slide to drive and move the first unlocking module 13 and the second unlocking module 14 so that one of the first unlocking module 13 and the second unlocking module 14 moves to a position corresponding to the operating member 11. Then, the operating member 11 can move to drive and move the first unlocking module 13 to unlock the first locking mechanism 4, or drive and move the second unlocking module 14 to unlock the second locking mechanism 5.

[0045] In another embodiment, the at least one operating member may include a first operating member and a second operating member configured to unlock a first locking mechanism and a second locking mechanism, respectively, In other words, the present invention may use two operating members to unlock two different locking mechanisms.

[0046] 1 and 8, in this embodiment, the operating member 11 may slide upward and downward relative to the frame 2, and the selection member 12 may slide leftward and rightward relative to the frame 2. The selection member 12 abuts against the operating member 11 to avoid erroneous operation. The selection member 12 may slide away from the operating member 11 so that the operating member 11 may slide. Specifically, the selection member 12 has an abutment portion 123, and the abutment portion 123 abuts against the operating member 11 so that the selection member 12 may lock the operating member 11 by the abutment portion 123 to avoid erroneous operation. The first unlocking module 13 is disposed between the operating member 11 and the selection member 12. The first unlocking module 13 may be movably disposed on the selection member 12 and may slide upward and downward relative to the selection member 12. The first unlocking module 13 abuts against the operating member 11. The first unlocking module 13 is connected to the wire of the first locking mechanism 4 and can drive the wire of the first locking mechanism 4 to move. The second unlocking module 14 is disposed between the operating member 11 and the selection member 12. The second unlocking module 14 may be movably disposed on the selection member 12 and may slide upward and downward relative to the selection member 12. The second unlocking module 14 abuts against the operating member 11. The second unlocking module 14 is connected to the second drag member 522 of the second locking mechanism 5 and can drive the second drag member 522 to move. The first unlocking module 13 is located on the right side of the handle 21 of the frame 2, and the second unlocking module 14 is located on the left side of the handle 21 of the frame 2. However, the arrangement of the first unlocking module 13 and the second unlocking module 14 is not limited to the above-mentioned manner. For example, the positions of the first unlocking module 13 and the second unlocking module 14 may be changed relative to each other.

[0047] To unlock the first unlocking module 4 or the second unlocking module 5, the selection member 12 may slide to slide the first unlocking module 13 and the second unlocking module 14, so that the operation member 11 may slide to press one of the first unlocking module 13 and the second unlocking module 14. For further explanation, the selection member 12 may move between a first position (as shown in FIG. 6 ) and a second position (as shown in FIG. 4 ) relative to the frame 2. When the selection member 12 is located in the first position, the operation member 11 may slide to drive and move the first unlocking module 13 to unlock the first locking mechanism 4. When the selection member 12 is located in the second position, the operation member 11 may slide to drive and move the second unlocking module 14 to unlock the second locking mechanism 5. Needless to say, in other embodiments, the first unlocking module 13 and the second unlocking module 14 may not abut the operation member 11. For example, the operating member 11 may be disposed in the space between the first unlocking module 13 and the second unlocking module 14. At this time, the selection member 12 may not abut against the operating member 11.

[0048] 3, 6 and 7, in this embodiment, the first unlocking module 13 includes a first rotating member 131 and a first sliding member 132. The first rotating member 131 is pivotally connected to the frame 2. The first locking mechanism 4 is connected to a position of the first rotating member 131 eccentric to the rotation center of the first rotating member 131. The first sliding member 132 is slidably disposed on the frame 2. The sliding direction of the first sliding member 132 is the same as the sliding direction of the operating member 11. Specifically, the selection member 12 has a first receiving hole 121, and an end of the first sliding member 132 is slidably inserted into the first receiving hole 121. The other end of the first sliding member 132 abuts against the operating member 11. The first sliding member 132 is configured to drive the first rotating member 131 to rotate. When the operating member 11 slides and presses the first slide member 132, the first slide member 132 drives the first rotating member 131 to rotate. Specifically, the first rotating member 131 has a first protruding portion 131a, and the first slide member 132 has a first engagement groove 132a. The first protruding portion 131a is slidably disposed in the first engagement groove 132a. The first slide member 132 can move to press the first protruding portion 131a to rotate the first rotating member 131. The first engagement groove 132a allows the first rotating member 131 to be stably disposed on the first slide member 132. More specifically, the first rotating member 131 has a first connecting member 131b, and the first connecting member 131b is eccentric with respect to the rotation center of the first rotating member 131 and is connected to the first lock mechanism 4. The first rotating member 131 may have two first connecting members 131b. The two first connecting members 131b may be symmetrically arranged on the first rotating member 131. The two first connecting members 131b are respectively connected to two wires of the first locking mechanism 4. In order to rotate the first rotating member 131, the operating member 11 may be actuated to slide and push the first sliding member 132 so that the first sliding member 132 slides and pushes the first protruding portion 131a.The first rotating member 131 rotates to pull the wire of the first locking mechanism 4 to unlock the frame 2. As a result, the frame 2 can be folded.

[0049] 3 to 5, in this embodiment, the second unlocking module 14 includes a second rotating member 141 and a second sliding member 142. The second rotating member 141 is pivotally connected to the frame 2. The second locking mechanism 5 is connected to a position of the second rotating member 141 eccentric to the rotation center of the first rotating member 141. The second sliding member 142 is slidably disposed on the frame 2. The sliding direction of the second sliding member 142 is the same as the sliding direction of the operating member 11. That is, the sliding directions of the first and second sliding members 132, 142 are both the same as the sliding direction of the operating member 11. Specifically, the selection member 12 has a second receiving hole 122, and an end of the second sliding member 142 is slidably inserted into the second receiving hole 122. The other end of the second sliding member 142 abuts against the operating member 11. The second slide member 142 is configured to drive the second rotating member 141 to rotate. When the operating member 11 slides and presses the second slide member 142, the second slide member 142 drives the second rotating member 141 to rotate. Specifically, the second rotating member 141 has a second protruding portion 141a, and the second slide member 142 has a second engagement groove 142a. The second protruding portion 141a is slidably disposed in the second engagement groove 142a. The second slide member 142 can move to rotate the second rotating member 141 by pressing the second protruding portion 141a. The second engagement groove 142a allows the second rotating member 141 to be stably disposed in the second slide member 142. More specifically, the second rotating member 141 has a second connecting member 141b, which is eccentric with respect to the rotation center of the second rotating member 141 and is connected to the second locking mechanism 5. To rotate the second rotating member 141, the operating member 11 may be actuated to slide and push the second sliding member 142 so that the second sliding member 142 slides and pushes the second protruding portion 141a. To unlock the wheel socket 3, the second rotating member 141 rotates to pull the second drag member 522 of the second locking mechanism 5 and eject the positioning post 523 from the positioning hole 31 of the wheel socket 3.As a result, the wheel socket 3 can rotate around the central shaft 32 .

[0050] Referring to FIG. 3, in this embodiment, the first unlocking module 13 and the second unlocking module 14 are arranged symmetrically. The first unlocking module 13 and the second unlocking module 14 may be realized by cooperation between a slide member and a rotating member, but this is not limited to such. In other embodiments, the first unlocking module 13 may only arrange the first slide member 132, and the first locking mechanism 4 is connected to the first slide member 132. The first slide member 132 may be pushed to slide to unlock the first locking mechanism 4. Alternatively, the second unlocking module 14 may only arrange the second slide member 142, and the second locking mechanism 5 is connected to the second slide member 142. The second slide member 142 may be pushed to slide to unlock the second locking mechanism 5. Alternatively, the first unlocking module 13 and the second unlocking module 14 may be arranged asymmetrically. One of the first unlocking module 13 and the second unlocking module 14 may be slidably disposed on the frame 2, and the other of the first unlocking module 13 and the second unlocking module 14 may be pivotally connected to the frame 2. For example, one of the first unlocking module 13 and the second unlocking module 14 may be a slide member slidably disposed on the frame 2, and the other of the first unlocking module 13 and the second unlocking module 14 may be a rotating member pivotally connected to the frame 2. The slide member and the rotating member are respectively connected to two different locking mechanisms and configured to unlock the two different locking mechanisms.

[0051] 3 and 9, in this embodiment, the first slide member 132 includes a first slide portion 132b, a first drive portion 132c connected to the first slide portion 132b, and a first limit portion 132d connected to the first drive portion 132c. The first slide portion 132b is slidably inserted into the selection member 12. The first drive portion 132c is connected to the first rotating member 131. The first limit portion 132d is disposed on the side of the first drive portion 132c. The second slide member 142 includes a second slide portion 142b, a second drive portion 142c connected to the second slide portion 142b, and a second limit portion 142d connected to the second drive portion 142c. The second slide portion 142b is slidably inserted into the selection member 12. The second drive portion 142c is connected to the second rotating member 141. The second limiting portion 142d is disposed on the side of the second driving portion 142c. When the operating member 11 slides to press one of the first unlocking module 13 and the second unlocking module 14 in order to prevent the other of the first unlocking module 13 and the second unlocking module 14 from interfering with the operating member 11, a first accommodation space 15 is formed between the first slide member 132 and the operating member 11, and a second accommodation space 16 is formed between the second slide member 142 and the operating member 11. When the operating member 11 slides to press one of the first unlocking module 13 and the second unlocking module 14, the operating member 11 may be accommodated in the first accommodation space 15 or the second accommodation space 16.

[0052] 10 to 13, the selection member 12 may move between a first position (as shown in FIG. 11) and a second position (as shown in FIG. 10) relative to the frame 2. As shown in FIG. 11, when the selection member 12 is located in the first position, the operating member 11 corresponds to the first unlocking module 13. As shown in FIG. 10, when the selection member 12 is located in the second position, the operating member 11 corresponds to the second unlocking module 14. During the operation of the selection member 12, the following misoperation may occur: The user essentially wants to operate and slide the selection member 12 toward the second position to make the operating member 11 correspond to the second unlocking module 14, and then operate and slide the operating member 11 to press the second unlocking module 14 to unlock the second unlocking module 5. However, the user may mistakenly operate the selection member 12 to slide toward the first position, causing the operation member 11 to correspond to the first unlocking module 13, and then push the operation member 11 to slide and press the first unlocking module 13. If there is a child sitting on the stroller 100, the frame 2 may be folded and may cause harm to the child sitting on the stroller 100. Therefore, in order to avoid the above-mentioned mistaken operation, an elastic member 17 may be disposed between the selection member 12 and the frame 2 and configured to move the selection member 12 away from the first position. Due to the elastic member 17, when the user mistakenly operates the selection member 12 to slide toward the first position, the selection member 12 compresses the elastic member 17. After the user releases the selection member 12, the selection member 12 returns to its original position due to the elastic force of the elastic member 17. Then, the selection member 12 drives the first slide member 132 of the first unlocking module 13 and the second slide member 142 of the second unlocking module 14 to return to their original positions so that the operating member 11 cannot slide and press the first unlocking module 13. As a result, the frame 2 is unlocked and cannot be folded, so as to enhance the safety of the stroller 100. After the selection member 12 returns to its original position, the selection member 12 abuts against the operating member 11 again to lock the operating member 11. Specifically, the elastic member 17 may be, but is not limited to, a spring.The elastic member 17 may be other elastic objects. In order to well position the elastic member 17, the frame 2 may have a protruding block 211, an end of the elastic member 17 may be sleeved in the protruding block 211 and abut the frame 2, and another end of the elastic member 17 may abut the selection member 12. However, the present invention is not limited to the above embodiment.

[0053] 10 and 11, in the second preferred embodiment of the present invention, the elastic member 17 provides an elastic force to make the selection member 12 return to the second position, and the second position of the selection member 12 may be set to be the initial state of the selection member 12. The operation member 11 may be directly pressed to press the second unlocking module 14 to unlock the second locking mechanism 5. When the frame 2 needs to be folded, the selection member 12 must slide from the second position to the first position and be held in the first position to make the operation member 11 correspond to the first unlocking module 13. Then, the operation member 11 can drive and slide the first unlocking module 13 to unlock the first locking mechanism 4. During the aforementioned operation, the elastic member 17 is compressed and deformed. When the selection member 12 is released, the selection member 12 returns to the second position due to the elastic force of the elastic member 17.

[0054] 2, in order to facilitate the operation of the unlocking device 1 of the present invention, the unlocking device 1 may be disposed on the upper side of the handle 21 of the frame 2. Of course, in other embodiments, the unlocking device 1 may be disposed in other positions on the frame 2.

[0055] It should be noted that the unlocking device 1 of the present invention is not limited to unlocking the frame folding mechanism and the wheel rotation orientation mechanism. The first connecting member 131b of the first unlocking module 13 and the second connecting member 141b of the second unlocking module 14 may be connected to other locking mechanisms of the stroller, such as a handle rotation locking mechanism. Furthermore, the unlocking device 1 of the present invention is not limited to being applied to a stroller. The unlocking device 1 may be used to unlock two different locking mechanisms in other fields.

[0056] 3 to 7, the operation of the unlocking device 1 of the present invention is depicted as follows. First, the operating member 11 abuts against the first slide member 132 and the second slide member 142 at the same time. When the first locking mechanism 4 needs to be unlocked, the selection member 12 is operated to move leftward, so that the selection member 12 is separated from the operating member 11 to unlock the operating member 11, driving the first unlocking module 13 and the second unlocking module 14 to move leftward, and the second slide member 142 of the second unlocking module 14 is also separated from the operating member 11, and the first slide member 132 of the first unlocking module 13 still abuts against the operating member 11. When the operating member 11 is pressed, the operating member 11 slides upward to push the first slide member 132 to slide. The first slide member 132 slides to push the first protruding part 131a to drive the first rotating member 131 to rotate. The first rotating member 131 rotates and pulls the wire of the first locking mechanism 4 so that the frame 2 is unlocked. As a result, the frame 2 can be folded. When the second locking mechanism 5 needs to be unlocked, the selection member 12 is separated from the operation member 11, and the selection member 12 is operated to slide rightward to drive the first unlocking module 13 and the second unlocking module 14 to move rightward, so as to unlock the operation member 11, and the first slide member 132 of the first unlocking module 13 is also separated from the operation member 11, and the second slide member 142 of the second unlocking module 14 is still adjacent to the operation member 11. When the operation member 11 is pressed, the operation member 11 slides upward to push the second slide member 142 to slide. The second slide member 142 slides and pushes the second protruding part 141a to drive the second rotation member 141 to rotate. The second rotating member 141 rotates to pull the second drag member 522 of the second locking mechanism 5, so that the positioning post 523 is ejected from the positioning hole 31 of the wheel socket 3, and then the wheel socket 3 is unlocked. As a result, the wheel socket 3 can rotate around the central shaft 32.

[0057] 14 and 15, the unlocking device 1 of the present invention may further include a retention mechanism 6 disposed on the operating member 11. The retention mechanism 6 can retain the operating member 11 in the unlocked position (as shown in FIG. 15) when the operating member 11 slides to unlock one of the first locking mechanism 4 and the second locking mechanism 5. Furthermore, the retention mechanism 6 can release the operating member 11 when the operating member 11 is actuated from the unlocked position.

[0058] In this embodiment, the holding mechanism 6 may include a first engagement member 61 and a second engagement member 62. The first engagement member 61 is fixed to the operating member 11. The second engagement member 62 is connected to the frame 2. If the unlocking device 1 is disposed on the handle 21 of the frame 2, the second engagement member 62 may be disposed on and connected to the handle 21 of the frame 2. The first engagement member 61 has a first inclined groove 611, a second inclined groove 612, a third inclined groove 613, and a fourth inclined groove 614 that are connected to each other. An end of the second engagement member 62 has an engagement portion 621.

[0059] When the user presses the operating member 11 to unlock the first locking mechanism 4 or the second locking mechanism 5, the engaging portion 621 of the second engaging member 62 moves along the first and second inclined grooves 611, 612, and then engages with the recess 615 between the second and third inclined grooves 612, 613 to hold the operating member 11 in the unlocked position (as shown in FIG. 15 ). At this time, the first locking mechanism 4 and the second locking mechanism 5 are held in the unlocked position. Furthermore, when the operating member 11 is actuated from the unlocked position (i.e., the operating member 11 located in the unlocked position is pressed again), the engaging portion 621 of the second engaging member 62 is disengaged from the recess 615 and moves along the third and fourth inclined grooves 613, 614 to release the operating member 11.

[0060] For example, the second locking mechanism 5 may be a wheel rotation orientation mechanism. When the operating member 11 is pressed to unlock the wheel rotation orientation mechanism, the retaining mechanism 6 retains the operating member 11 in the unlocked position so that the wheels can still rotate freely even if a user releases the operating member 11. Furthermore, when the operating member 11 is actuated from the unlocked position, the retaining mechanism 6 releases the operating member 11 so that the operating member 11 slides to lock the wheel rotation orientation mechanism and then the wheels are locked.

[0061] 16 and 17, the at least one operating member of the present invention may include a first operating member 111 and a second operating member 112, where the first operating member 111 drives and moves the first unlocking module 13 to slide to unlock the first locking mechanism 4, and the second operating member 112 drives and moves the second unlocking module 14 to slide to unlock the second locking mechanism 5. In other words, the present invention may use two operating members 111, 112 to unlock two different locking mechanisms 4, 5. In this embodiment, the retention mechanism 6 may be disposed in the second operating member 112, but is not limited to such. In another embodiment, the retention mechanism 6 may be disposed in the first operating member 111.

[0062] When a user presses the second operating member 112 to unlock the second locking mechanism 5, the engaging portion 621 of the second engaging member 62 moves along the first and second inclined grooves 611, 612, and then engages with the recess 615 between the second and third inclined grooves 612, 613 to hold the second operating member 112 in the unlocked position (as shown in FIG. 17). At this time, the second locking mechanism 5 is held in the unlocked position. Furthermore, when the second operating member 112 is actuated from the unlocked position (i.e., when the second operating member 112 located in the unlocked position is pressed again), the engaging portion 621 of the second operating member 62 is disengaged from the recess 615 and moves along the third and fourth inclined grooves 613, 614 to release the second operating member 112, so that the second operating member 112 slides to lock the second locking mechanism 5.

[0063] In an exemplary embodiment, the second locking mechanism 5 can be one of the locking mechanisms that need to hold or maintain a state, such as, but not limited to, wheel brake and wheel rocking lock, and the first locking mechanism 4 can be one of, but not limited to, handle translation, wheel brake, handle angle adjustment, frame folding and wheel rocking lock, but their functions do not overlap with each other.

[0064] 18 and 19, the retaining mechanism 7 is pivotally connected to the operating member 11 and includes an engagement portion 71 and an elastic portion 72. Furthermore, the frame 2 has an engagement hole 24. In this embodiment, the operating member 11 may be configured to unlock the above-mentioned second locking mechanism 5. As shown in FIG. 18, the engagement portion 71 of the retaining mechanism 7 abuts against the frame 2, and the elastic portion 72 of the retaining mechanism 7 is compressed by the frame 2 before the operating member 11 slides to unlock the second locking mechanism 5. As shown in FIG. 19, when the operating member 11 slides to unlock the second locking mechanism 5, the elastic portion 72 provides an elastic force that drives and rotates the retaining mechanism 7 so that the operating member 11 is held in the unlocked position, and the engagement portion 71 engages with the engagement hole 24. The user presses the retaining mechanism 7 to disengage the engagement portion 71 from the engagement hole 24 and release the operating member 11 so that the operating member 11 slides to lock the second locking mechanism 5.

[0065] 20 to 24, the at least one operating member of the present invention may include a first operating member 111 and a second operating member 112, and the first operating member 111 drives and moves the first slide member 132 to slide to unlock the first lock member, and the second operating member 112 drives and moves the second slide member 142 to slide to unlock the second lock mechanism 5. In this embodiment, the selection member 12 is movably disposed on the frame 2 so that it can move between a first position (as shown in FIG. 21) and a second position (as shown in FIG. 23) relative to the frame 2. First, the first slide member 132 and the second slide member 142 abut against the selection member 12 as shown in FIG. 20. When the first locking mechanism 4 needs to be unlocked, the selection member 12 is operated to move leftward (as shown in FIG. 21 ) so that the selection member 12 is separated from the first slide member 132 to unlock the first operating member 111, and the second slide member 142 still abuts against the selection member 12. At this time, the first accommodation space 15 is formed between the first slide member 132 and the selection member 12. When the first operating member 111 is pressed (as shown in FIG. 22 ), the first operating member 111 slides upward to push and slide the first slide member 132 to unlock the first locking mechanism 4. When the second locking mechanism 5 needs to be unlocked, the selection member 12 is operated to move rightward (as shown in FIG. 23 ) so that the selection member 12 is separated from the second slide member 142 to unlock the second operating member 112, and the first slide member 132 still abuts against the selection member 12. At this time, a second receiving space 16 is formed between the second slide member 142 and the selection member 12. When the second operating member 12 is pressed (as shown in FIG. 24 ), the second operating member 112 slides upward to push and slide the second slide member 142 to unlock the second locking mechanism 5. How to unlock the first and second locking mechanisms 4, 5 has been described in detail above, so a repeated description will not be repeated here.

[0066] 25 to 28, the at least one operating member of the present invention may include a first operating member 111 and a second operating member 112, where the first operating member 111 slides to drive the first slide member 132 to unlock the first locking mechanism 4, and the second operating member 112 slides to drive the second slide member 142 to unlock the second locking mechanism 5. In this embodiment, the selection member 12 is pivotally connected to the aforementioned frame 2 such that the selection member 12 can rotate between a first position (as shown in FIG. 27) and a second position (as shown in FIG. 25) relative to the aforementioned frame 2. Initially, the selection member 12 is disposed in the second position such that the selection member 12 is separated from the second slide member 142 to unlock the second operating member 112, and the first slide member 132 abuts against the selection member 12 to lock the first operating member 111. At this time, a second accommodation space 16 is formed between the second slide member 142 and the selection member 12. In this embodiment, a torsion spring or the like can be used to maintain the selection member 12 in the second position. When the second operation member 112 is pressed (as shown in FIG. 26), the second operation member 112 slides upward to push and slide the second slide member 142 to unlock the second locking mechanism 5. When the first locking mechanism 4 needs to be unlocked, the selection member 12 is operated to rotate counterclockwise (as shown in FIG. 27), such that the selection member 12 is separated from the first slide member 132 to unlock the first operation member 111, and the second slide member 142 abuts against the selection member 12 to lock the second operation member 112. At this time, a first accommodation space 15 is formed between the first slide member 132 and the selection member 12. When the first operating member 111 is pressed (as shown in FIG. 28), the first operating member 111 slides upwards to push and slide the first slide member 132 in order to unlock the first locking mechanism 4. It should be noted that if the selection member 12 is released from the first position shown in FIG. 27, the torsion spring rotates the selection member 12 to the second position shown in FIG. 25 to avoid accidental operation of the first operating member 111.How to unlock the first and second locking mechanisms 4, 5 has been described in detail above, so a repeated description will not be repeated here.

[0067] As described above, the present invention uses at least one operating member to drive and move the first unlocking module to unlock the first locking mechanism or drive and move the second unlocking module to unlock the second locking mechanism. In an embodiment, a selection member is movably disposed on the frame and can be moved between a first position and a second position relative to the frame. When the selection member is disposed in the first position, the first locking mechanism corresponds to the operating member such that the operating member can slide to drive and move the first unlocking module to unlock the first locking mechanism. When the selection member is disposed in the second position, the second locking mechanism corresponds to the operating member such that the operating member can slide to drive and move the second unlocking module to unlock the second locking mechanism. Thus, the present invention does not need to dispose two independent unlocking devices to unlock the first and second locking mechanisms. That is, the present invention can use one single unlocking device to unlock two different locking mechanisms. Therefore, the manufacturing cost is reduced, the unlocking device of the present invention takes up less space in the stroller, and is easy and convenient to operate.

[0068] In another embodiment, the present invention may use a retaining mechanism to retain the operating member in an unlocked position when the operating member slides to unlock the first locking mechanism and the second locking mechanism. Thus, the first locking mechanism and the second locking mechanism can be retained in an unlocked state until the operating member is actuated from the unlocked position. For example, the second locking mechanism may be a wheel rotation orientation mechanism, and the retaining mechanism may retain the operating member in the unlocked position when the operating member slides to unlock the second locking mechanism. When the user presses the operating member to unlock the wheel rotation orientation mechanism, the wheel rotation orientation mechanism is retained in the unlocked position so that the wheels can still rotate freely even if the user releases the operating member. Furthermore, when the operating member is actuated from the unlocked position, the retaining mechanism allows the operating member to slide to lock the wheel rotation orientation mechanism and then release the operating member so that the wheels are locked.

[0069] Those skilled in the art will readily observe that numerous modifications and variations of the apparatus and method may be made while retaining the teachings of this invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
