Abstract
Description
Technical Field
[0001] This invention relates to the field of children's products technology, specifically to a children's stroller. Background Technology
[0002] Strollers are essential transportation tools for children's travel. To adapt to various usage scenarios, strollers are typically reversible, meaning they can be used in a forward-facing mode with the child facing away from the parent and a rear-facing mode with the child facing the parent. However, in existing technologies, when reversing a stroller, there is a problem of the push rod and base frame gap causing the stroller's hand to be pinched or squeezed. Summary of the Invention
[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a stroller that avoids pinching a person's hand during reversing operations.
[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A stroller for children includes: The base support includes the front support and the rear support; A push rod is rotatably disposed relative to the base support about a first axis extending in a left-right direction, and the push rod has a pushing position and a reversing position when rotatable about the first axis; A connector is movably disposed at the lower part of the push rod; When the push rod is in the pushing position, the connector is sequentially connected to the front support or the rear support; when the push rod is in the reversing position, the connector can move away from the front support or the rear support so that there is a set interval distance between the connector and the bottom support; or, when the push rod is in the reversing position, there is a set interval distance between the connector and the bottom support.
[0005] In some embodiments, when the push rod is in the push position, the front or rear support, the connector, and the push rod extend in the same straight direction.
[0006] In some embodiments, the stroller has a forward-facing use state and a rearward-facing use state. When the stroller is in both the forward-facing and rearward-facing use states, the push rod is in the push position, and the front support, the connector, and the push rod extend in the same straight line direction.
[0007] In some embodiments, the stroller further includes a seat assembly rotatably mounted on the base support about a second axis extending vertically, and a push rod rotatably mounted on the seat assembly about a first axis.
[0008] In some embodiments, the stroller further includes a movable member movably disposed on the push rod, the movable member having a first position and a second position relative to the push rod; The movable component is connected or cooperates with the connecting component to drive the connecting component to move away from the front support or the rear support when the movable component moves from the first position to the second position.
[0009] In some embodiments, the stroller further includes a limiting structure for limiting the push rod in a pushing position. The limiting structure includes a limiting member slidably disposed on the push rod and a limiting groove disposed on the seat assembly. The limiting member is provided with a limiting portion. When the push rod is in the pushing position, the limiting portion is located in the limiting groove. When the limiting portion is disengaged from the limiting groove, the push rod is rotatable to a reversing position. The connector is slidably disposed at the lower part of the push rod along the length extension direction of the push rod. The limiting member is connected or cooperates with the connecting member to drive the connecting member to slide a first stroke away from the front bracket or the rear bracket when the limiting part is disengaged from the limiting groove. The movable component is the limiting component.
[0010] In some embodiments, when the push rod moves from the push position to the reversing position, the connector slides relative to the push rod to move the connector away from the front bracket or the rear bracket; The seat assembly is also provided with a guide groove extending in the circumferential direction of the push rod rotating around the second axis. The guide groove is connected to the limiting groove. When the limiting part is disengaged from the limiting groove, the limiting part enters the guide groove. When the push rod rotates to the reversing position, the limiting part slides along the guide groove. The limiting member is connected or cooperates with the connecting member to drive the connecting member to slide a second stroke away from the front bracket or the rear bracket when the limiting part slides along the guide groove.
[0011] In some embodiments, the limiting member has a first mating part, and the connecting member has a second mating part. When the push rod moves from the pushing position to the reversing position, the first mating part and the second mating part cooperate, causing the connecting member to slide relative to the push rod in a direction away from the front support or the rear support.
[0012] In some embodiments, the first mating part is located below the second mating part, and when the push rod moves from the pushing position to the reversing position, the first mating part abuts against the lower part of the second mating part.
[0013] In some embodiments, the sliding stroke of the limiting member is less than the sliding stroke of the connecting member. When the push rod is in the reversing position, the limiting member can continue to slide a third stroke away from the front bracket or the rear bracket, and the limiting member disengages from the connecting member. Alternatively, the sliding stroke of the limiting member is the same as the sliding stroke of the connecting member; Alternatively, the sliding stroke of the limiting member is greater than the sliding stroke of the connecting member.
[0014] In some embodiments, when the push rod moves from the push position to the reversing position, the limiting part moves from bottom to top along the guide groove, and the limiting groove is located at the lower part of the guide groove. When the push rod is in the reversing position, the limiting part is located at the upper part of the guide groove. The limiting grooves are respectively provided at both ends of the guide groove.
[0015] In some embodiments, the limiting groove extends along the sliding direction of the limiting member, and when the push rod is in the pushing position and drives the limiting member to slide relative to the push rod, the limiting part disengages from the limiting groove.
[0016] In some embodiments, the stroller further includes a drive assembly for driving the limiting portion out of the limiting groove, the drive assembly including an operating member movably disposed on the push rod and a flexible connector with one end connected to the operating member, the other end of the flexible connector being connected to the limiting member; And / or, the stroller further includes a first elastic member for driving the limiting member to slide in the direction of causing the limiting portion to enter the limiting groove, the two ends of the first elastic member being respectively disposed on the push rod and the limiting member.
[0017] In some embodiments, the stroller further includes a locking mechanism disposed between the seat assembly and the base support to lock their relative positions, and the stroller further includes an actuation mechanism disposed between the push rod and the locking mechanism to drive the locking mechanism to unlock when the push rod moves from the push position to the reversing position.
[0018] In some embodiments, the stroller further includes a second elastic member for driving the connector toward the front support or the rear support, the two ends of the second elastic member being respectively disposed on the push rod and the connector.
[0019] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art: When the stroller of the present invention is in the reversing operation, after the push rod moves from the pushing position to the reversing position around the first axis, the connecting part and the bottom bracket can have an interval distance that is adapted to the human hand, thereby avoiding injury to the human hand during the rotation of the push rod when the stroller is in the reversing operation.

Detailed Implementation
[0022] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0023] In the following description, the directions such as "front," "back," "left," "right," "up," and "down" are defined according to the conventional observation perspective of a stroller in its unfolded state as viewed by those skilled in the art. The definitions of directions are merely for the convenience of describing the invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the invention.
[0024] like Figures 1-9 As shown, the stroller in this embodiment includes a base frame, a seat assembly 2, and a push rod 3.
[0025] In this embodiment, the base support includes a front support 11 and a rear support 12, which are connected at their upper parts. A front wheel assembly is provided at the bottom of the front support 11, and a rear wheel assembly is provided at the bottom of the rear support 12.
[0026] The seat assembly 2 is rotatably mounted on a base support about a second axis 42 extending vertically. Specifically, the base support also includes a cross brace 13 extending horizontally, and at least one of the front support 11 and the rear support 12 is connected to the cross brace 13. The seat assembly 2 is rotatably mounted on the cross brace 13 about the second axis 42.
[0027] When the seat assembly 2 rotates relative to the base support around the second axis 42, the stroller can be configured for both forward-facing and rear-facing use. When the stroller is in the forward-facing position, the child sits in the seat assembly 2 with their back to the parent, as shown in the image. Figure 1 As shown. When the stroller is in rear-facing use, the child sits in the seat assembly 2 facing the parent, as shown. Figure 9 As shown.
[0028] The stroller also includes a locking mechanism that is locked in both forward-facing and rearward-facing positions. This locking mechanism secures the relative position between the seat assembly 2 and the base frame, preventing the seat assembly 2 from rotating relative to the base frame around the second axis 42. When the locking mechanism is unlocked, the seat assembly 2 can rotate around the second axis 42, allowing the stroller to switch between forward-facing and rearward-facing positions.
[0029] The push rod 3 is rotatably mounted on the seat assembly 2 around a first axis 41, which extends in the left-right direction. When the seat assembly 2 rotates relative to the base support around a second axis 42 to change the direction of the stroller, it drives the push rod 3 to rotate synchronously around the second axis 42 relative to the base support.
[0030] A linkage mechanism is provided between the push rod 3 and the locking mechanism. When the stroller is in forward or backward use, the push rod 3 rotates around the first axis 41, and the locking mechanism can be unlocked through the linkage mechanism.
[0031] Specifically, the push rod 3 rotates around the first axis 41 to have a pushing position and a reversing position. When the stroller is in the forward-facing or rearward-facing use mode, the push rod 3 is in the pushing position and the locking mechanism is in the locked state. When the push rod 3 rotates around the first axis 41 to the reversing position, the locking mechanism is in the unlocked state.
[0032] The specific structural forms of the locking mechanism and the linkage mechanism can adopt the structures in the existing technology, which will not be described in detail here.
[0033] The stroller also includes a limiting structure. When the push rod 3 is in the push position, the limiting structure limits the position of the push rod 3 so that it cannot rotate relative to the seat assembly 2 around the first axis 41.
[0034] The limiting structure includes a limiting member 5 slidably mounted on the push rod 3. The limiting member 5 includes a limiting part 51, and a limiting groove 21 is provided on the seat assembly 2. When the push rod 3 is in the pushed position, the limiting part 51 is located in the limiting groove 21, such as... Figure 1 , Figure 2 and Figure 9 As shown. After the limiting part 51 disengages from the limiting groove 21, the push rod 3 can rotate relative to the seat assembly 2 around the first axis 41, as shown. Figures 3-8 As shown.
[0035] The seat assembly 2 is also provided with a guide groove 22, which extends along the circumferential direction of the push rod 3 rotating around the first axis 41, and communicates with the limiting groove 21. When the limiting part 51 disengages from the limiting groove 21, the limiting part 51 enters the guide groove 22, as... Figures 3-8As shown. When the push rod 3 rotates around the first axis 41 to the reversing position, the limiting part 51 slides along the extension direction of the guide groove 22, and at the same time, the limiting member 5 slides relative to the push rod 3.
[0036] In this embodiment, the limiting groove 21 is located at the lower part of the guide groove 22. When the push rod 3 moves from the pushing position to the reversing position, the limiting part 51 moves from bottom to top along the guide groove 22. When the push rod 3 is in the reversing position, the limiting part 51 is located at the upper part of the guide groove 22.
[0037] In this embodiment, the limiting grooves 21 are respectively disposed at both ends of the guide groove 22. When the stroller is in a forward-facing use state and a backward-facing use state, the limiting part 51 is located in different limiting grooves 21, such as... Figure 1 and Figure 9 As shown.
[0038] The limiting groove 21 extends along the sliding direction of the limiting member 5. When the push rod 3 is in the pushing position and drives the limiting member 5 to slide relative to the push rod 3, the limiting part 51 is dislodged from the limiting groove 21 and enters the guide groove 22.
[0039] The stroller also includes a drive assembly, which is connected to or cooperates with the limiting member 5. When the push rod 3 is in the push position, operating the drive assembly causes the limiting member 5 to slide relative to the push rod 3, thereby causing the limiting part 51 to disengage from the limiting groove 21 and enter the guide groove 22.
[0040] In this embodiment, the driving assembly includes an operating member 61 movably mounted on the push rod 3 and a flexible connector 62 with one end connected to the operating member 61. The other end of the flexible connector 62 is connected to the limiting member 5. Figure 13 As shown. When the push rod 3 operates the operating component 61 in the pushed position, that is, the limiting component 5 is pulled to slide relative to the push rod 3 through the flexible connecting component 62.
[0041] The stroller also includes a first elastic element 7, with its two ends respectively mounted on the push rod 3 and the limiting element 5. When the push rod 3 moves from the reversing position to the pushing position along the guide groove 22, when the limiting element 5 moves to the position where the limiting part 51 is directly opposite the limiting groove 21, the elastic force of the first elastic element 7 drives the limiting element 5 to slide automatically, so that the limiting part 51 enters the limiting groove 21.
[0042] like Figures 1-13As shown, the stroller also includes a connector 8, which is movably disposed at the lower part of the push rod 3. When the push rod 3 is in the push position, the connector 8 is sequentially connected to the front support 11 or the rear support 12. Preferably, the front support 11 or the rear support 12, the connector 8, and the push rod 3 extend in the same straight line direction, making the stroller's external structure complete, neat, and aesthetically pleasing. In this embodiment, when the stroller is in the forward-facing and backward-facing use states, the front support 11, the connector 8, and the push rod 3 all extend in the same straight line direction, such as... Figure 1 and Figure 9 As shown.
[0043] When the push rod 3 is in the reversing position, there may be no gap between the connector 8 and the base support, or the gap may be too small to accommodate a finger. However, when the connector 8 is subjected to external force, it can move away from the front support 11 or the rear support 12, thereby creating a set gap distance L between the connector 8 and the base support. The set gap distance L is adapted to the size of a human hand, so that when the seat assembly 2 drives the push rod 3 to rotate around the second axis 42 during the reversing process, when a human hand is inserted into the gap between the connector 8 and the base support, a force will be applied to the connector 8, causing it to move away from the front support 11 or the rear support 12 relative to the push rod 3, thereby creating the set gap distance L between the connector 8 and the base support, thus preventing the human hand from being pinched.
[0044] Alternatively, when the push rod 3 moves to the reversing position, there can be a set interval distance L between the connecting piece 8 and the base bracket.
[0045] The stroller also includes a movable member movably mounted on the push rod 3, which has a first position and a second position relative to the push rod 3. The movable member is connected to or cooperates with the connecting member 8, thereby driving the connecting member 8 to move away from the front support 11 or the rear support 12 when the movable member moves from the first position to the second position.
[0046] In this embodiment, the connecting member 8 is slidably disposed at the lower part of the push rod 3 along the length extension direction of the push rod 3. The movable member is the limiting member 5. When the limiting member 5 is in the first position, the limiting member 5 is located in the limiting groove 21. When the limiting member 5 is in the second position, the limiting member 5 is located in the guide groove 22, which can be located at the lower or upper part of the guide groove 22. When the push rod 3 moves from the pushing position to the reversing position, the limiting member 5 connects or cooperates with the connecting member 9, thereby driving the connecting member 8 to slide relative to the push rod 3 in a direction away from the front bracket 11 or the rear bracket 12 during the sliding process of the limiting member 5 relative to the push rod 3.
[0047] like Figures 10-13As shown, the limiting member 5 also has a first mating part 52, and the connecting member 8 is provided with a second mating part 81. When the push rod 3 moves from the pushing position to the reversing position, the first mating part 52 and the second mating part 81 cooperate, causing the connecting member 8 to slide relative to the push rod 3 in a direction away from the front support 11 or the rear support 12.
[0048] Specifically, during the process of the limiting part 51 disengaging from the limiting groove 21, through the cooperation of the first mating part 52 and the second mating part 81, the limiting member 5 drives the connecting member 8 to slide relative to the push rod 3 for a first stroke, such as... Figure 3 As shown. At this time, the gap between the connector 8 and the base bracket does not reach the set gap L, but the connector 8 will not block the push rod 3 from rotating relative to the seat assembly 2 around the first axis 41, so that the push rod 3 can rotate to the reversing position.
[0049] Of course, after the connector 8 slides the first stroke relative to the push rod 3, there can also be a set interval distance L between the connector 8 and the bottom bracket. At this time, the sliding stroke of the connector 8 is less than the sliding stroke of the limiter 5.
[0050] After the limiting part 51 enters the guide groove 22, it moves along the guide groove 22 to the upper part of the guide groove 22, that is, during the process of the push rod 3 rotating to the reversing position, through the cooperation of the first mating part 52 and the second mating part 81, the limiting part 5 drives the connecting part 8 to continue sliding relative to the push rod 3 for a second stroke, such as... Figure 4 As shown.
[0051] After the connecting piece 8 slides a second stroke relative to the push rod 3, the first mating part 52 and the second mating part 81 can disengage. The connecting piece 8 can then continue to slide a third stroke relative to the push rod 3, thereby creating a set interval distance L between the connecting piece 8 and the base bracket. During this process, the limiting member 5 remains stationary relative to the push rod 3, meaning that the sliding stroke of the connecting piece 8 is greater than the sliding stroke of the limiting member 5. Figure 5 and Figure 6 As shown.
[0052] Of course, after the connector 8 slides a second stroke relative to the push rod 3, there can also be a set interval distance L between the connector 8 and the bottom bracket. At this time, the sliding stroke of the connector 8 is the same as the sliding stroke of the limiter 5.
[0053] In this embodiment, the first mating part 52 is located below the second mating part 81. When the push rod 3 moves from the pushing position to the reversing position, the limiting member 5 slides upward along the extension direction of the push rod 3. The first mating part 52 abuts against the lower part of the second mating part 81, thereby pushing the connecting member 8 to slide upward relative to the push rod 3 in sync, that is, to slide the first stroke and the second stroke away from the front bracket 11 or the rear bracket 12.
[0054] In this embodiment, the limiting member 5 further includes a seat 53, a limiting part 51 is fixedly connected to the seat 53, and a first mating part 52 is integrally formed with the seat 53. Figure 13 As shown.
[0055] In this embodiment, the push rod 3 has a cavity extending along its length, and both the first mating part 52 and the seat 53 are located within the cavity of the push rod 3. A sliding groove 31 extending along its length is provided on the push rod 3, and a limiting part 51 extends from the sliding groove 31 to the outside of the cavity of the push rod 3 to insert into the limiting groove 21 or the guide groove 22. Figures 10-13 As shown.
[0056] like Figures 10-13 As shown, the stroller also includes a second elastic element 9, with its two ends respectively disposed on the push rod 3 and the connecting member 8. When the push rod 3 moves from the reversing position to the pushing position, the limiting member 5 slides downward along the push rod 3, causing the first mating part 52 to move away from the second mating part 81. The elastic force of the second elastic element 9 then drives the connecting member 8 downward, i.e., to slide towards the front support 11 or the rear support 12.
[0057] In other embodiments, the movable component can also be an operating component 61, which is connected to the connecting component 8 via a flexible connector. The initial position of the operating component 61 is the first position. When the operating component 61 is pressed, it moves to the second position. During the process of pressing the operating component 61 to move it from the first position to the second position, the limiting component 5 disengages from the limiting groove 21, and the connecting component 8 moves away from the front support 11 or the rear support 12.
[0058] The process of switching the stroller from a forward-facing to a rear-facing configuration is as follows: When the stroller is in forward-facing mode, operating the control element 61 pulls the limiting element 5 upward relative to the push rod 3 via the flexible connector 62, causing the limiting part 51 to disengage from the limiting groove 21 and enter the guide groove 22. This, in turn, causes the connector 8 to simultaneously slide upward relative to the push rod 3 for the first stroke. Figure 3 As shown.
[0059] The push rod 3 rotates forward relative to the seat assembly 2 around the first axis 41, causing the limiting part 51 to move upward along the guide groove 22, so that the limiting part 5 continues to slide upward relative to the push rod 3, driving the connecting part 8 to slide upward relative to the push rod 3 in a second stroke. Figure 4 As shown.
[0060] When the push rod 3 is held and the seat assembly 2 and the push rod 3 as a whole rotate relative to the base bracket around the second axis 42, when a finger is inserted into the gap between the connector 8 and the base bracket, the connector 8 continues to slide upward relative to the push rod 3 for a third stroke, such as... Figure 5 As shown.
[0061] The seat assembly 2 and push rod 3 are rotated 180° relative to the base support around the second axis 42, as follows: Figure 7 As shown.
[0062] The push rod 3 is rotated rearward relative to the seat assembly 2 around the first axis 41, causing the limiting part 51 to move downward along the guide groove 22, so that the limiting member 5 slides downward relative to the push rod 3 until the limiting part 51 is directly opposite the limiting groove 21. Figure 8 As shown.
[0063] Under the elastic force of the first elastic member 7, the limiting member 5 slides downward along the push rod 3, causing the limiting part 51 to enter the limiting groove 21. Under the elastic force of the second elastic member 9, the connecting member 8 slides downward along the push rod 3 and sequentially connects with the front bracket 11, so that the stroller is in a rear-facing use state. Figure 9 As shown.
[0064] The process of switching a stroller from rear-facing to front-facing use is the same as above.

They should not be construed as limiting the scope of protection of the present invention.
