Description

[0001] This application claims priority to Chinese Patent Application No. 202521363017.3, filed with the Chinese Patent Office on June 30, 2025, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This utility model relates to the field of children's products technology, and in particular to an unlocking component and a children's product. Background Technology

[0003] When designing children's products, especially those that need to be frequently unfolded and folded (such as strollers, highchairs, and cribs), a key design consideration is how to effectively achieve compact storage. To achieve this, many products employ foldable designs. However, such designs typically involve multiple moving parts and joints that need to remain stable during use to ensure the product's safety and functionality. In practice, these joints are usually secured by some form of locking mechanism. When the product needs to be transformed from an unfolded state to a folded state, or vice versa, the user must manually unlock these joints. If each joint needs to be unlocked or locked individually, this not only increases operational complexity but also may lead to safety risks due to users forgetting to unlock or lock certain parts. For example, an incompletely locked joint could cause the product to fold accidentally during use, posing a potential hazard to children.

[0004] Finding a way to simplify the joint locking and unlocking process, enabling users to complete the operation more conveniently and quickly, and ensuring that all relevant parts are correctly locked or unlocked, has become an important challenge for designers in this field. Utility Model Content

[0005] The main objective of this invention is to provide an unlocking component and a child-friendly device, which aims to provide an unlocking component that simplifies the process of locking and unlocking joints.

[0006] To achieve the above objectives, the unlocking component proposed in this utility model includes:

[0024] The second locking structure includes a second locking member movably disposed in the second connecting portion and a second mating portion disposed in the second mounting portion. The second locking member has a second locking position and a second unlocking position during its active stroke.

[0025] The first locking member is convex with the second locking member so that when the first locking member is reset and moved, the second locking member is driven to move toward the second unlocked position.

[0026] In one embodiment, the child-friendly device includes a carrier, the carrier comprising:

[0027] Support frame; and,

[0028] A pusher includes at least one push rod and a connecting rod. The push rod extends vertically and its lower end is rotatably connected to the support frame about a transverse axis, so that the push rod can be folded toward the support frame. The connecting rod is rotatably connected to the upper end of the push rod.

[0029] The push rod has a first connecting part and a second connecting part at both ends, the support frame has a first mounting part, and the connecting rod has a second mounting part at the end near the push rod.

[0030] In one embodiment, the pusher includes:

[0031] The handle extends laterally; and,

[0032] The two push rods have their upper ends connected to both ends of the handle rod, and the upper ends of the two push rods are rotatably connected by a connecting rod.

[0033] The connecting rod is bent, with one end rotatably sleeved on the second connecting part about a longitudinally extending axis, and the other end rotatably connected to the second mounting part about a longitudinally extending axis.

[0034] In one embodiment, a third locking structure is provided between the connecting rod and the handle rod, the third locking structure comprising:

[0035] A third mating part is provided on the handle bar; and

[0036] The third locking element is movably disposed on the connecting rod and has a third locking position and a third unlocking position during its active stroke;

[0037] The first locking member is also drively connected to the third locking member so as to drive the third locking member to move toward the third unlocking position when the first locking member is reset.

[0038] In one embodiment, the support frame includes a first bracket and a second bracket, corresponding to a first leg and a second leg. One end of the first leg and the second leg are rotatably connected about a laterally extending axis to form a first joint. The first leg and the second leg can be folded together and unfolded apart in the longitudinal direction.

[0039] The vehicle also includes:

[0040] The first rolling part and the second rolling part are respectively installed on the first support leg and the second support leg.

[0043] The sliding member is connected to the first bracket via a transmission mechanism, and the second rolling part is hinged to the sliding member with a linkage rod, so that when the fourth locking structure is in the fourth unlocked state, the second rolling part can swing towards the first leg under its own gravity, thereby driving the sliding member to slide towards the first leg. The sliding member drives the first leg to fold towards the second leg through the transmission mechanism.

[0044] In one embodiment, the vehicle includes a treadmill.

[0045] In the technical solution of this utility model, during the relative movement of the first connecting part and the first mounting part, the first mating part can rotate to abut against the first locking member and push the first locking member to move. As the first connecting part and the first mounting part continue to rotate, the thrust of the first mating part on the first locking member is removed. At this time, the first reset member drives the first locking member to reset and move. Since the first locking member and the second locking member are connected by transmission, when the first locking member resets and moves, it drives the second locking member to move toward the second unlocking position. During the rotation of the first movable connecting structure, the first locking structure is unlocked, and the second locking structure is unlocked synchronously. It is not necessary to unlock each locking structure one by one, which simplifies the user's operation steps and provides an unlocking component that can simplify the joint locking and unlocking process.

[0067] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0068] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0069] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0070] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0071] When designing children's products, especially those that need to be frequently unfolded and folded (such as strollers, highchairs, and cribs), a key design consideration is how to effectively achieve compact storage. To achieve this, many products employ foldable designs. However, such designs typically involve multiple moving parts and joints that need to remain stable during use to ensure the product's safety and functionality. In practice, these joints are usually secured by some form of locking mechanism. When the product needs to be unfolded to folded, or vice versa, the user must manually unlock these joints. If each joint needs to be unlocked or locked individually, this not only increases the complexity of operation but also may lead to safety risks due to users forgetting to unlock or lock certain parts. For example, an incompletely locked joint could cause the product to fold accidentally during use, posing a potential hazard to children. Therefore, finding a method to simplify the joint locking and unlocking process, allowing users to complete the operation more conveniently and quickly, and ensuring that all relevant parts are correctly locked or unlocked, has become a significant challenge for designers in this field.

[0072] This invention proposes an unlocking component, which aims to provide an unlocking component that can simplify the joint locking and unlocking process.

[0073] Please see Figures 1 to 4 In one embodiment of this utility model, the unlocking component includes a connecting component, a first locking structure 50, a first reset member, and a second locking structure 70. The connecting component includes a first movable connecting structure and a second movable connecting structure. The first movable connecting structure includes a first mounting portion 10 and a first connecting portion 20 that are rotatably connected. The second movable connecting structure includes a second mounting portion 30 and a second connecting portion 40 that are rotatably connected. The first locking structure 50 includes a first locking member 501 that is movably disposed in the first connecting portion 20, and a first mating portion 502 disposed in the first mounting portion 10 (for coupling). Figure 5 The first mating part 502 is rotatable to abut against the first locking member 501 and push the first locking member 501 to move; the first reset member is disposed between the first connecting part 20 and the first mounting part 10, and is used to drive the first locking member 501 to reset and move after the pushing force of the first mating part 502 on the first locking member 501 is removed; the second locking structure 70 includes a second locking member 701 movably disposed in the second connecting part 40 and a second mating part disposed in the second mounting part 30, the second locking member 701 having a second locking position and a second unlocking position in its active stroke; wherein, the first locking member 501 and the second locking member 701 are connected in a transmission manner, so that when the first locking member 501 resets and moves, the second locking member 701 is driven to move toward the second unlocking position.

[0074] It should be noted that the first mounting part 10 and the first connecting part 20 achieve rotational locking in the unfolded state of the vehicle. This is specifically achieved through the engagement of an electric bell tooth. When the vehicle needs to be folded, the electric bell tooth is unlocked, allowing the first mounting part 10 and the first connecting part 20 to rotate relative to each other. The electric bell tooth is a mechanical component that can impede or unlock joint rotation. When installed, the electric bell tooth needs to work in conjunction with a slider, elastic elements, etc., to achieve stable locking and convenient unlocking of the joint. In the locked state, both ends of the electric bell tooth are simultaneously inserted into two tooth slots, impeding the rotation of the first mounting part 10 and the first connecting part 20. In the unlocked state, flipping the first connecting part 20 causes the first end of the electric bell tooth to completely disengage from one tooth slot and the slider, thus unlocking the first mounting part 10 and the first connecting part 20.

[0075] The first locking member 501 is movably disposed in the first connecting part 20. The first locking member 501 is normally fixed relative to the first connecting part 20. Through the first mating part 502 and the first reset member, the first locking member 501 has two states:

[0076] After the first mating part 502 pushes the first locking member 501 to move, the first connecting part 20 is allowed to move freely.

[0077] After the pushing force of the first mating part 502 on the first locking member 501 is removed, it moves under the action of the first reset member, and the first locking member 501 can be reset and moved.

[0078] Understandably, when the carrier 1000 is in the unfolded state, the first locking structure 50 has the first locking member 501 in a normal state and fixed relative to the first connecting part 20. During the folding process of the carrier 1000, the first connecting part 20 can rotate relative to the first mounting part 10, and the first mating part 502 can be driven to rotate by the first mounting part 10, thereby rotating to abut against the first locking member 501 and pushing the first locking member 501 to move. Then, the first reset member drives the first locking member 501 to reset and move. During this process, based on the transmission connection between the first locking member 501 and the second locking member 701, the second locking member 701 unlocks in conjunction, and the second connecting part 40 and the second mounting part 30 can rotate, realizing the folding of the carrier.

[0079] Please see Figure 1 , Figure 13 and Figure 14 The second locking structure 70 includes a second mating part and a second locking member 701. The second mating part is disposed in the second mounting part 30. The second locking member 701 is movably disposed at the upper end of the first connecting part 20 and has a second locking position and a second unlocking position in its active stroke. The first locking member 501 is convexly connected to the second locking member 701 so that when the first locking member 501 is reset and moved, the second locking member 701 is driven to move toward the second unlocking position.

[0080] Understandably, the second mating part is provided on the second mounting part 30 for mating with the second locking member 701.

[0081] The second locking member 701 is movably disposed at the upper end of the first connecting part 20 and has two movable positions:

[0082] Second locking position: In this position, the second locking member 701 cooperates with the second mating part to lock the connection between the second mounting part 30 and the first connecting part 20.

[0083] Second unlocked position: In this position, the second locking member 701 is disengaged from the second mating part, allowing free movement between the second mounting part 30 and the first connecting part 20.

[0084] Understandably, since the first reset member is located between the first locking member 501 and the first connecting portion 20, it is typically a spring or other elastic element. When the first connecting portion 20 is unfolded, the first locking member 501 is reset and moved under the action of the first reset member.

[0085] When the pushing force of the first mating part 502 on the first locking member 501 is removed, the first reset member will push the first locking member 501 to reset and move. The first locking member 501 is connected to the second locking member 701 in a transmission manner: when the first locking member 501 resets and moves, it will drive the second locking member 701 to move towards the second unlocking position, and finally unlock the connection between the second mounting part 30 and the first connecting part 20.

[0086] The user operates the relevant structure to first unlock the first mounting part 10 and the first connecting part 20, and then unlock the first locking member 501 during their rotation, thereby simultaneously unlocking the second locking member 701, and finally unlocking the connection between the second mounting part 30 and the first connecting part 20.

[0087] It should also be noted that, in order to enable the second locking member 701 to automatically switch from the second unlocking position to the second locking position, a return spring can be provided between the second locking member 701 and the first connecting part 20. When the second locking member 701 switches from the second locking position to the second unlocking position, the return spring stores elastic potential energy. When locking is required, the return spring can automatically switch the second locking member 701 from the second unlocking position to the second locking position to achieve automatic locking.

[0088] In the technical solution of this utility model, during the relative movement of the first connecting part 20 and the first mounting part 10, the first mating part 502 can rotate to abut against the first locking member 501 and push the first locking member 501 to move. As the first connecting part 20 and the first mounting part 10 continue to rotate, the pushing force of the first mating part 502 on the first locking member 501 is removed. At this time, the first reset member drives the first locking member 501 to reset and move. Since the first locking member 501 is connected to the second locking member 701, when the first locking member 501 resets and moves, it drives the second locking member 701 to move toward the second unlocking position. During the rotation of the first movable connecting structure, the first locking structure 50 is unlocked, and the second locking structure 70 is unlocked synchronously. It is not necessary to unlock each locking structure one by one, which simplifies the user's operation steps, so as to provide an unlocking component that can simplify the joint locking and unlocking process.

[0089] Specifically, please refer to Figure 1 and Figure 2 In one embodiment, the connecting component includes a connector 90, the two ends of which are movably connected to the first mounting portion 10 and the second mounting portion 30 to form a first connecting portion 20 and a second connecting portion 40.

[0090] Thus, by providing a first locking structure 50 and a second locking structure 70 at both ends of the connector 90, both ends of the connector 90 can move freely relative to the first mounting part 10 and the second mounting part 30.

[0091] For example, when applied to children's beds, a first locking structure 50 and a second locking structure 70 can be set at both ends of a guardrail, allowing the guardrail to be unlocked simultaneously and enabling the guardrail to quickly release the restriction on movement.

[0092] The first locking member 501 is able to reciprocate due to the action of the first reset member.

[0093] Specifically, please refer to Figure 4 In this embodiment, the first locking member 501 is movably disposed in the direction close to the first mounting portion 10, the first reset member includes a first reset spring (not shown); the first mating portion 502 includes a protrusion disposed on the first connecting portion 20.

[0094] Initially, the first locking member 501 is separated from the first mating part 502. As the first connecting part 20 moves, the first mating part 502 comes into contact with the first locking member 501 until it pushes the first locking member 501 to move in the direction close to the first mounting part 10. As the first locking member 501 moves and the first connecting part 20 continues to move, the first locking member 501 is separated from the first mating part 502 again. At this time, the first locking member 501 is mainly subjected to the traction force of the first reset member, so that it can move and reset in the opposite direction.

[0095] The first locking element 501 can be returned to its original position by the action of the first return spring so that it can be locked next time.

[0096] Further, please refer to Figures 8 to 9 In this embodiment, the second locking member 701 is movably disposed in the direction close to the second mounting portion 30; a connecting portion 110 is provided between the first locking member 501 and the second locking member 701. Thus, when it is necessary to lock the connecting member 90 relative to the first mounting portion 10 and the second mounting portion 30, the second locking member 701 is moved in the direction close to the second mounting portion 30 to achieve locking engagement with the second mating portion; when it is necessary to rotate the connecting member 90 relative to the first mounting portion 10 and the second mounting portion 30, the second locking member 701 is moved in the direction away from the second mounting portion 30 to disengage from the second mating portion.

[0097] By connecting the first locking member 501 and the second locking member 701 through the connecting part 110, the second locking structure 70 can be unlocked simply by having the first locking member 501 move the second locking member 701 away from the second mounting part 30 via the connecting part 110.

[0098] The connecting part 110 can be a rope, a connecting rod 32, or other connecting parts 110. Of course, other possible components can also be used. The specific components can be determined according to the actual situation. This specification does not limit this aspect in the embodiments.

[0099] Further, please refer to Figure 1 In one embodiment, the connecting portion 110 includes a cable; a second reset member is provided between the second locking member 701 and the second connecting portion 40 to reset the second locking member 701 to the second locking position.

[0100] By setting a cable, the first locking member 501 can drive the second locking member 701 to move away from the second mounting part 30 through the connecting part 110. However, when the second locking member 701 moves in the direction close to the second mounting part 30, it needs to be reset by the second reset member so that the second locking member 701 can automatically reset from the second unlock position to the second locking position.

[0101] This utility model also proposes a child's toy, which includes an unlocking component. The specific structure of the unlocking component is as described in the above embodiments. Since this child's toy adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0102] Specifically, please refer to Figure 1 , Figure 2 , Figure 6 , Figure 10 and Figure 15 The children's equipment includes a carrier 1000, which includes a support frame 100 and a pusher 3. The pusher 3 includes at least one push rod 31 and a connecting rod 32. The push rod 31 extends vertically and is rotatably connected to the support frame 100 about a transverse axis so that the push rod 31 can be folded towards the support frame 100. The connecting rod 32 is rotatably connected to the upper end of the push rod 31. The two ends of the push rod 31 form a first connecting part 20 and a second connecting part 40. The support frame 100 is provided with a first mounting part 10, and the end of the connecting rod 32 near the push rod 31 forms a second mounting part 30.

[0103] It should be noted that the specific direction of the longitudinal direction is not limited; it can be up and down, left and right, or forward and backward. The lateral direction is the direction perpendicular to the longitudinal direction. When the longitudinal direction is forward and backward, the lateral direction is left and right. The longitudinal and lateral directions are not limited here. In the actual use of vehicle 1000, the longitudinal direction can be regarded as the forward direction of vehicle 1000, that is, the forward and backward direction. The lateral direction is the width direction of vehicle 1000, that is, the left and right direction. The up and down direction can be regarded as the height direction of vehicle 1000.

[0104] It is understandable that the first connecting part 20 and the first mounting part 10 are rotatably connected about the laterally extending axis c, that is, the first connecting part 20 and the support frame 100 are rotatably connected at the hinge point.

[0105] It should be noted that axis c is not completely horizontal, but is set at a certain angle to the horizontal.

[0106] When the vehicle 1000 needs to be folded, the push rod 31 can be folded along direction B towards the support frame 100. The push rod 31 can change from an upright state to a folded state, moving closer to the support frame 100, thereby reducing the overall volume of the vehicle 1000. When the vehicle 1000 needs to be unfolded for use, the push rod 31 can return to an upright state, providing stable support.

[0107] By combining the folding action of push rod 31 with the overall folding action of vehicle 1000, the user's operation process is simplified. In use, push rod 31 provides stable support, and in the folded state, the folding of push rod 31 does not affect the compactness of the overall structure.

[0108] Furthermore, in this embodiment, the pusher 3 includes a handle 33 and two push rods 31. The handle 33 extends laterally. The two first connecting parts 20 are correspondingly hinged to the first mounting part 10, and their upper ends are connected to both ends of the handle 33.

[0109] The handle 33 extends laterally, that is, the handle 33 is parallel to the width direction of the vehicle 1000. In the unfolded state, the push rod 31 remains upright, and the handle 33 extends horizontally, so that the user can hold the handle 33 to easily push the vehicle 1000.

[0110] Furthermore, in this embodiment, the upper ends of the two push rods 31 are rotatably connected by a connecting rod 32; the connecting rod 32 is bent, with one end rotatably sleeved on the second connecting part 40 about the longitudinally extending axis, and the other end rotatably connected to the second mounting part 30 about the longitudinally extending axis.

[0111] It should be noted that in the folded state, when the two push rods 31 need to be folded inward along the lateral direction, the handle 33 and connecting rod 32 located between the two push rods 31 need to be folded inward along the lateral direction in order to avoid interference when the two push rods 31 are folded inward.

[0112] It is understandable that one end of the connecting rod 32 is rotatably sleeved onto the upper end of the push rod 31 about the longitudinally extending axis. That is, one end of the connecting rod 32 can rotate about the rotation axis b and is hinged to the upper end of the push rod 31.

[0113] The other end of the connecting rod 32 is rotatably connected to one end of the handle 33 about the longitudinally extending axis. That is, the other end of the connecting rod 32 can rotate about the rotation axis a and is hinged to one end of the handle 33.

[0114] In the deployed state, the push rod 31 remains upright, and the bent portion of the connecting rod 32 can adapt to the angle between the push rod 31 and the handle rod 33, keeping the handle rod 33 horizontal. The user can grip the handle rod 33 to push the vehicle 1000. At this time, both the first locking member 501 and the second locking member 701 are in the locked state.

[0115] In the folded state, both the first locking member 501 and the second locking member 701 are unlocked, allowing the push rod 31 to swing inward. At this time, the curved portion of the connecting rod 32 allows for an angle change between the push rod 31 and the handle rod 33, enabling both push rods 31 to fold inward and the handle rod 33 to fold accordingly, reducing the overall size. This further improves the comfort and stability of the vehicle 1000 during use, and also makes the vehicle 1000 more compact in the folded state, facilitating carrying and storage.

[0116] Furthermore, in this embodiment, a third locking structure 80 is provided between the connecting rod 32 and the handle rod 33. The third locking structure 80 includes a third mating part 802 and a third locking member 801. The third mating part 802 is disposed on the handle rod 33. The third locking member 801 is movably disposed on the connecting rod 32 and has a third locking position and a third unlocking position in its active stroke. The first locking member 501 is also connected to the third locking member 801 in a transmission manner so that when the first locking member 501 is reset and moved, the third locking member 801 is driven to move toward the third unlocking position.

[0117] Understandably, the third mating part 802 is provided on the handle lever 33 for mating with the third locking member 801.

[0118] The third locking element 801 is movably mounted on the connecting rod 32 and has two movable positions:

[0119] Third locking position: In this position, the third locking member 801 engages with the third mating part 802 to lock the connection between the connecting rod 32 and the handle rod 33.

[0120] Third unlocked position: In this position, the third locking member 801 is disengaged from the third mating part 802, allowing free movement between the connecting rod 32 and the handle rod 33.

[0121] When the first locking member 501 is movable relative to the first connecting part 20, it not only unlocks the connection between the push rod 31 and the first mounting part 10, and the connection between the push rod 31 and the connecting rod 32, but also unlocks the connection between the connecting rod 32 and the handle 33 through the transmission connection. The user only needs to perform one operation to unlock multiple parts.

[0122] It should also be noted that, in order to enable the third locking member 801 to automatically switch from the third unlocking position to the third locking position, a reset spring can also be provided between the third locking member 801 and the push rod 31 to achieve automatic locking.

[0123] The transmission connection between the first locking member 501 and the third locking member 801 enables the coordinated unlocking of the push rod 31, connecting rod 32, and handle rod 33. This design not only simplifies the user's operation but also improves the stability and safety of the vehicle 1000 during use and folding.

[0124] Specifically, in this embodiment, the first locking member 501 is elastically extended and retracted on the first connecting part 20 through the first elastic member. The first locking member 501 can be pushed by the first mating part 502 to overcome the elastic force. After the pushing force of the first mating part 502 is removed, it resets and moves under the action of the elastic force.

[0125] The first locking member 501 can extend or retract along the hole or track at the lower end of the push rod 31 under the action of the first elastic member.

[0126] When the vehicle 1000 is in the unfolded state, the first locking member 501 extends and engages with a slot, abutting against and fixing the push rod 31 to prevent it from moving during use.

[0127] The elastic telescopic installation method allows the first locking member 501 to securely lock the push rod 31 in the locked state, preventing accidental unlocking. Furthermore, the first locking member 501 is elastically telescopically mounted on the lower end of the push rod 31 via a first elastic element, allowing it to move flexibly in both locked and unlocked states, ensuring the stability of the carrier 1000 during use and its ease of folding.

[0128] Specifically, please refer to Figure 1 In this embodiment, the first locking member 501 is connected to the third locking member 801 by a cable.

[0129] The first locking member 501, the third locking member 801, and the third locking member 801 are interconnected by one or more cables. Through the connection of the cables, the movement of the first locking member 501 will simultaneously drive the movement of the third locking member 801.

[0130] The multiple locking components can be linked together via cable connections, ensuring that all relevant parts unlock synchronously during the unlocking process, thus improving the consistency and reliability of the operation.

[0131] Specifically, please refer to Figure 1 , Figure 2 , Figure 6 , Figure 10 , Figure 15 and Figure 17In this embodiment, the support frame 100 includes a first bracket 1 and a second bracket 2, correspondingly including a first leg 11 and a second leg 21. One end of the first leg 11 and the second leg 21 are rotatably connected around a laterally extending axis to form a first joint 111. The first leg 11 and the second leg 21 can be folded closer together and unfolded further apart in the longitudinal direction. The carrier 1000 also includes a first rolling part 41, a second rolling part 42, a slider 5, and a fourth locking structure 6. The first rolling part 41 and the second rolling part 42 are respectively installed on the first leg 11 and the second leg 21. The second rolling part 42 is connected to the second bracket 2 through a mounting part 9, and the second rolling part 42 can swing longitudinally relative to the mounting part 9. The slider 5 moves along the first... The second leg 21 is movably connected to the second leg 21 along its length, and the sliding member 5 is located between the first joint 111 and the second rolling part 42; the fourth locking structure 6 is disposed between the sliding member 5 and the second leg 21, and has a fourth locking state that restricts the sliding member 5 from sliding, and a fourth unlocking state that releases the restriction on the sliding member 5; wherein, the sliding member 5 is connected to the first bracket 1 by a transmission mechanism 7, and the second rolling part 42 is hinged to the sliding member 5 by a linkage rod 8, so that when the fourth locking structure 6 is in the fourth unlocking state, the second rolling part 42 can swing towards the first leg 11 under its own gravity, thereby driving the sliding member 5 to slide towards the first leg 11, and the sliding member 5 drives the first leg 11 to fold towards the second leg 21 through the transmission mechanism 7.

[0132] It is understood that the first support 1 and the second support 2 are the main support structures of the carrier 1000. The first support 1 includes a first leg 11 and the second support 2 includes a second leg 21. The structure of the first support 1 is used for mounting the first rolling part 41 and the structure of the second support 2 is used for mounting the second rolling part 42. The first support 1 can rotate about the laterally extending axis so that the first leg 11 and the second leg 21 can be folded together and unfolded apart in the longitudinal direction.

[0133] One end of the first leg 11 and the second leg 21 are connected by a transverse axis, forming a rotatable first joint 111. The first joint 111 allows the two legs to move closer (folded) or further apart (unfolded) in the longitudinal direction (i.e., the forward direction of the vehicle 1000). The first joint 111 can be an integrally formed component with the first leg 11, with the second leg 21 rotatably connected to the first joint 111; it can also be an integrally formed component with the second leg 21, with the first leg 11 rotatably connected to the first joint 111; or it can be a separate component located between the first leg 11 and the second leg 21, enabling a rotatable connection, with both the first leg 11 and the second leg 21 rotatably connected to the first joint 111. In one embodiment, the first leg 11 has a protrusion, and the second leg 21 is rotatably connected to the protrusion via a pivot, with the protrusion forming the first joint 111.

[0134] The first rolling part 41 and the second rolling part 42 can be wheels or other rolling devices, respectively mounted on the first leg 11 and the second leg 21, so as to enable the vehicle 1000 to move when it is deployed.

[0135] The slider 5 can move along the length of the second leg 21 and is located between the first joint 111 and the second rolling part 42. It can be understood that the slider 5 and the second leg 21 can be in the form of sliding engagement with a slider through a groove. Of course, the slider 5 can also be in the form of a sleeve fitted on the second leg 21. Compared with the form of slider and groove engagement, the structure of the sleeve fitted on the second leg 21 is more stable, and the contact area is larger and the interaction force is more uniform.

[0136] The fourth locking structure 6 is disposed between the sliding member 5 and the second support leg 21. The fourth locking structure 6 can lock the position of the sliding member 5 (i.e., the fourth locking structure 6 is in a fourth locked state) or release the sliding member 5 (i.e., the fourth locking structure 6 is in a fourth unlocked state), allowing the sliding member 5 to move freely along direction E. The fourth locking structure 6 can be a slot and a hook respectively disposed on the sliding member 5 and the second support leg 21. When the hook and slot are engaged, the fourth locking structure 6 is in a fourth locked state; when the hook disengages from the slot, the fourth locking structure 6 is in a fourth unlocked state. Of course, the specific form of the fourth locking structure 6 is not limited to the above examples; the specific form can be determined according to the actual situation. This specification does not limit this embodiment.

[0137] It should also be noted that the fourth locking structure 6 can be unlocked by setting an unlocking component 61 that is connected to the fourth locking structure 6 in a transmission manner. In this embodiment, the fourth locking component of the fourth locking structure 6 can be unlocked by pulling the unlocking component 61 in the direction D.

[0138] The sliding member 5 is connected to the first support 1 through a transmission mechanism 7. When the sliding member 5 moves, the movement of the first leg 11 can be affected by the transmission mechanism 7. The transmission mechanism 7 can be a linkage mechanism, a gear chain mechanism, or a combination thereof to achieve transmission, so as to ensure that the mechanism can transmit in a reliable and efficient manner.

[0139] The two ends of the linkage rod 8 are hinged to the second rolling part 42 and the sliding member 5, respectively. Specifically, the linkage rod 8 is rotatably connected to the second rolling part 42 around the rotation axis L. When the fourth locking structure 6 is in the unlocked state, the second rolling part 42 will swing towards the first leg 11 due to its own gravity, and the linkage rod 8 will then drive the sliding member 5 to slide towards the first leg 11. Through the action of the transmission mechanism 7, the movement of the sliding member 5 will cause the first leg 11 to fold towards the second leg 21.

[0140] When the fourth locking structure 6 is in the fourth unlocked state, the restriction on the sliding member 5 is released, allowing the second rolling part 42 to swing towards the first support leg 11 under its own weight. A linkage rod 8 is hinged between the second rolling part 42 and the sliding member 5, allowing the second rolling part 42 to drive the sliding member 5 to slide towards the first support leg 11 via the linkage rod 8. A transmission mechanism 7 is provided between the sliding member 5 and the first support 1. When the sliding member 5 moves towards the first support leg 11 along the length direction of the second support leg 21, the transmission mechanism 7 causes the first support leg 11 of the second support 2 to rotate around the laterally extending axis. The rotation of the line allows the first leg 11 and the second leg 21 to fold together longitudinally, thereby allowing the first rolling part 41 and the second rolling part 42, which are respectively installed on the first leg 11 and the second leg 21, to fold together longitudinally. During the folding process, the second rolling part 42 can complete the folding of the vehicle 1000 by its own gravity, without requiring any additional operation from the user. The entire process is almost automatically completed by gravity and mechanical linkage. The user only needs to unlock the fourth locking structure 6 to trigger the folding process, thus improving the ease of folding the existing vehicle 1000.

[0141] Further, please refer to Figure 1 , Figure 2 and Figure 6In this embodiment, the transmission mechanism 7 includes a first connecting rod 71, a second connecting rod 72, and a transmission rod 73. Both the first connecting rod 71 and the second connecting rod 72 extend vertically. The lower end of the first connecting rod 71 is hinged to the upper end of the first extension 12, and the lower end of the second connecting rod 72 is hinged to the sliding member 5. The upper end of the second connecting rod 72 is hinged to the upper end of the first connecting rod 71 to form a second joint 74. The second joint 74 forms the first mounting portion 10. The transmission rod 73 extends longitudinally, and one end of it is hinged to the second connecting rod 72. The first bracket 1 also includes a first extension 12 extending upward from the first leg 11 at the first joint 111. The middle part of the first extension 12 is rotatably connected to the lower end of the first connecting rod 71 about a laterally extending axis to form a third joint 75. The first extension 12 has an upper end and a lower end that rotate about the third joint 75. The upper end of the first extension 12 is hinged to the other end of the transmission rod 73.

[0142] The second joint 74 is the hinge point between the first link 71 and the second link 72. The second link 72 can rotate about the rotation axis d relative to the second joint 74. When the slider 5 slides forward longitudinally, the lower end of the second link 72 can swing about its upper end along the direction H, thereby driving the upper end of the first link 71 to rotate about the rotation axis f of the lower end of the first link 71 through the second joint 74.

[0143] Understandably, referring to Figure 12 The second joint 74 can be an integrally formed component with the first connecting rod 71, with the second connecting rod 72 rotatably connected to the first joint 71; or it can be an integrally formed component with the second connecting rod 72, with the first connecting rod 71 rotatably connected to the second joint 74; or it can be a separate component located between the first connecting rod 71 and the second connecting rod 72 to achieve a rotatable connection, with both the first connecting rod 71 and the second connecting rod 72 rotatably connected to the second joint 74. In one embodiment, the upper ends of the first connecting rod 71 and the second connecting rod 72 are each provided with a separate mounting portion 9, and the upper ends of both the first connecting rod 71 and the second connecting rod 72 are rotatably connected to the mounting portion 9 via a pivot, with the second joint 74 formed at the mounting portion 9.

[0144] The third joint 75 is formed in the middle of the first extension 12 and the lower end of the first link 71. The middle of the first extension 12 rotates around the axis e of the third joint 75. When the first extension 12 rotates along the direction F, it can drive the first leg 11 to rotate around the axis e.

[0145] Understandably, when the second link 72 is driven by the slider 5 to slide toward the first leg 11, the rear end of the transmission rod 73 can rotate relative to the slider 5 around the rotation axis i, and the front end of the transmission rod 73 can rotate relative to the upper end of the first extension 12 around the rotation axis h, so that the transmission rod 73 moves forward longitudinally, thereby applying a forward force to the upper end of the first extension 12, so that the upper end of the first extension 12 can rotate forward longitudinally around its axis. At this time, the lower end of the first extension 12 can rotate backward longitudinally around its axis. Therefore, the lower end of the first extension 12 can drive the first leg 11 to rotate around the rotation axis of the first extension 12, and finally drive the first rolling part 41 to flip and fold backward longitudinally.

[0146] Combination Figure 11 , Figure 12 and 16 When the slider 5 moves, it transmits motion to the first link 71 via the second link 72. The first link 71 then transmits the motion to the first extension 12 via the transmission rod 73. The rotation of the first extension 12 drives the first leg 11 to move, thus enabling the folding or unfolding of the first leg 11 and the second leg 21. This design ensures smooth motion transmission while maintaining structural flexibility and reliability through multiple hinge points. This allows all components of the carrier 1000 to work collaboratively during folding and unfolding.

[0147] It should be noted that in actual use, in order to ensure the stability of the vehicle 1000, at least two second rolling parts 42 are generally set. The two second rolling parts 42 are arranged at intervals in the horizontal direction, and the distance between the two second rolling parts 42 is set to be greater than the horizontal dimensions of the first support 1 and the second support 2. Therefore, when folding, in addition to minimizing the space occupied by the first rolling part 41 and the second rolling part 42 in the vertical direction, it is also necessary to fold the second rolling part 42 inward in the horizontal direction as much as possible.

[0148] Furthermore, in order to reduce the lateral space occupied by vehicle 1000, please refer to... Figure 1 , Figure 6 and Figure 7 In this embodiment, the second rolling part 42 is rotatably connected to the mounting part 9 so that the second rolling part 42 can be oscillating in the longitudinal direction.

[0149] The second rolling part 42 can swing longitudinally relative to the mounting part 9. In this way, the second rolling part 42 can not only maintain the normal use position, but also swing inward or outward when folded, thereby reducing the occupancy of lateral space.

[0150] When the carrier 1000 is in the deployed state, the second rolling part 42 remains in the normal position, located outside the second bracket 2, to ensure normal use.

[0151] When the vehicle 1000 needs to be folded, the second rolling part 42 can swing inward. During the folding process, the second rolling part 42 will not hinder the movement of other parts, and at the same time, it will reduce the lateral size of the entire vehicle 1000, making it more compact.

[0152] By reducing the lateral space occupied, the lateral dimensions of the vehicle 1000 in the folded state are effectively reduced, making the folded vehicle 1000 easier to store and carry, thereby improving portability and simplifying the folding process.

[0153] Specifically, please refer to Figure 1 and Figure 6 In this embodiment, the rotation axis of the second rolling part 42 and the mounting part 9 is inclined to the lateral direction, so that the second rolling part 42 moves inward in the lateral direction when it swings toward the first support leg 11.

[0154] It is understandable that the rotation axis k between the second rolling part 42 and the mounting part 9 is not completely horizontal, but is inclined at a certain angle to the lateral direction. Therefore, the second rolling part 42 does not simply swing vertically or horizontally, but has a certain tilt angle when swinging around the direction G. It will not only move and fold in the longitudinal direction, but also move and fold inward in the lateral direction, which can further reduce the lateral dimension of the vehicle 1000.

[0155] The tilted rotation axis makes the path of the second rolling part 42 more reasonable during folding, reducing the complexity of the folding process and helping to maintain the stability of the structure during folding. This ensures that the components can move in coordination, improving portability and the smoothness of the folding process.

[0156] Further, please refer to Figure 1 , Figure 2 and Figure 6 In this embodiment, the rotation axes of the lower ends of the first link 71 and the second link 72 are inclined to the lateral direction, so that when the first link 71 and the second link 72 rotate in the longitudinal direction, they can move laterally inward.

[0157] It should be noted that you should refer to [link / reference]. Figure 1 and Figure 6 The rotation axes of the lower ends of the first link 71 and the second link 72 are inclined to the lateral direction, that is, the rotation axis f of the first link 71 is inclined to the lateral direction, and the rotation axis j of the second link 72 is inclined to the lateral direction.

[0158] To make it easier to understand, let's take the vehicle 1000 as a stroller as an example. The area corresponding to the first link 71 and the second link 72 in the lateral direction is the area where the child sits. Therefore, it needs to be set as spacious as possible. So, when folding, in order to avoid the first link 71 and the second link 72 occupying too much lateral space, the rotation axis of the lower end of the first link 71 and the second link 72 is set at an angle to the lateral direction, which can make the first link 71 and the second link 72 swing along the lateral direction.

[0159] Of course, to make the vehicle 1000 more robust, there are two of each of the first link 71 and the second link 72. The two first links 71 are spaced apart in the lateral direction, and the two second links 72 are also spaced apart in the lateral direction. The child's seating space is located between the two first links 71 and the two second links 72. The rotation axis of the lower end of the first link 71 and the second link 72 on each side can be symmetrically arranged about the axis of symmetry extending in the longitudinal direction. When folding, the two first links 71 can swing inward towards each other in the lateral direction, and the two second links 72 can swing inward towards each other in the lateral direction.

[0160] At this point, both push rods 31, handle rods 33, and two connecting rods 32 are unlocked, making way for the two first connecting rods 71 ​​to swing laterally toward each other and the two second connecting rods 72 to swing laterally toward each other.

[0161] In this embodiment, during the process of the vehicle 1000 changing from an unfolded state to a folded state, the push rod 31 moves closer to the first support leg 11, the first connecting rod 71 and the second connecting rod 72 move closer, the first rolling part 41 and the second rolling part 42 move closer, and the two second rolling parts 42 move closer, the two connecting rods 32 move closer, and the two connecting rods 32 and the handle rotate relative to each other, exhibiting a change in relative position. Finally, the vehicle 1000 presents a smaller folded state.

[0162] Specifically, in this embodiment, the carrier 1000 includes a treadmill. The treadmill is a stroller for conveniently carrying an infant during outdoor activities. The treadmill's quick-folding design allows the stroller to be easily stored or transported when not in use.

[0163] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
