Description

Technical Field

[0001] This application relates to the field of baby strollers, and more particularly to a folding mechanism for a baby stroller and the baby stroller itself. Background Technology

[0002] In the stroller industry, typical automatic snap-fit ​​structures usually feature articulated mechanisms that interlock with each other. These mechanisms, controlled by linkages or external force, create a locking and releasing system. The primary purpose of this system is to control the unfolding and folding of the stroller frame. Typically, the automatic snap-fit ​​assembly and tray are separate and cannot be connected. Because of the complex articulated structure of this type of stroller, it is inconvenient to use and prone to causing folding difficulties and damaging the internal structure. Furthermore, the separate tray and automatic snap-fit ​​assembly are cumbersome and awkward, and interference during folding makes folding very difficult. Therefore, there is an urgent need for a simpler folding mechanism that allows for smooth and convenient unfolding and folding. Summary of the Invention

[0003] This application aims to at least solve one of the technical problems existing in the prior art. Therefore, one object of this application is to provide a folding mechanism for a stroller, wherein the folding mechanism is provided with an elastic element that enables the automatic folding of the front guard.

[0004] This application further proposes a stroller employing the aforementioned folding mechanism.

[0005] According to an embodiment of this application, the stroller folding mechanism includes a connecting seat, a handlebar connector pivotally connected to the connecting seat, a front leg connector pivotally connected to the handlebar connector, a rear leg connector pivotally connected to the front leg connector, and a front guard pivotally connected to a rotating member. The rear leg connector is foldable and unfoldable relative to the front leg connector. The folding mechanism includes a rotating member, and connecting rods extend from both ends of the front guard. The rotating member is pivotally connected to the connecting seat, and the connecting rods are detachably engaged with the rotating member. The rotating member has a first extension portion, and the connecting seat has a first connecting portion. The folding mechanism further includes an elastic element, one end of which is connected to the first extension and the other end of which is connected to the first connecting post. During the unfolding of the rear foot connector, the rear foot connector abuts against the first extension, and the rear foot connector pushes the rotating member to rotate counterclockwise, causing the rotating member to rotate and unfold the front guard. During the folding of the rear foot connector, the rear foot connector disengages from the first extension, and the elastic element pulls the rotating member to rotate clockwise, causing the rotating member to rotate and fold.

[0006] According to the folding mechanism of the stroller according to the embodiments of this application, by setting a rotating member and an elastic member, the front guard can be unfolded and automatically folded. When the stroller is unfolded, the rear leg connector pushes the first extension, causing the rotating member to rotate counterclockwise relative to the connecting seat. The counterclockwise rotation of the rotating member drives the front guard, which is engaged with it, to unfold and rotate counterclockwise, so that the front guard and the stroller unfold synchronously, making the unfolding smoother and the operation more convenient. After the stroller is unfolded, the rear leg connector can abut against and support the rotating member, and the elastic member connects the first extension and the first... The connecting column can limit the first limiting part, preventing unstable shaking of the rotating part and further improving the stability of the rotating part, thereby improving the stability of the front guard when unfolded. When the stroller is folded, the rear leg connecting part disengages from the first extension part, and the rotating part is no longer supported by the rear leg connecting part. At this time, the elastic part returns to its original length, and the elastic part drives the rotating part to rotate clockwise. The clockwise rotation of the rotating part drives the front guard to fold. By setting the elastic part, the automatic folding of the front guard is realized, and the folding is smoother, improving the convenience of use.

[0007] In some embodiments, the rear foot connector has a bent portion that bends toward the rotating member. During the unfolding of the rear foot connector, the bent portion abuts against the first extension of the rotating member, and during the retraction of the rear foot connector, the bent portion disengages from the first extension.

[0008] Specifically, the rotating component further includes: a body and a second extension, wherein the first extension and the second extension protrude from the side of the body away from the connecting seat, the first extension and the second extension are connected, and the first extension and the second extension extend in opposite directions.

[0009] Furthermore, the first extension has a first contact surface located on the inner side of the first extension. During the unfolding of the rear foot connector, the bent portion contacts the first contact surface, and during the retraction of the rear foot connector, the bent portion disengages from the first contact surface.

[0010] Furthermore, the first extension has a second connecting post, which protrudes from the side of the first extension near the connecting seat, and the two ends of the elastic member are respectively connected to the first connecting post and the second connecting post.

[0011] Specifically, the second extension has a second contact surface located on the outer side of the second extension. The driver connector has a protruding locking block corresponding to the second extension. When the front guard is unfolded into a horizontal position, the locking block abuts against the second contact surface.

[0012] In some embodiments, a receiving area is defined at the connection between the first extension and the second extension, and an abutment is provided in the receiving area. The abutment protrudes from the side of the body away from the connector and fits against the first extension and the second extension.

[0013] In some embodiments, the folding mechanism further includes a support plate, which has a bent structure. One end of the support plate is fixedly connected to the connecting seat, and the other end of the support plate is pivotally connected to the rotating member.

[0014] Specifically, the support plate includes a fixing part, which bends and extends toward the rotating member to form a support part. The fixing part is fixedly connected to the connecting seat, and the support part is pivotally connected to the rotating member.

[0015] Furthermore, the rotating member is provided with a limiting groove, and the support part is disposed in the limiting groove. When the front guard is unfolded into a horizontal position, the support part abuts against one wall of the limiting groove; when the front guard is fully retracted, the support part abuts against the other wall of the limiting groove.

[0016] In some embodiments, the folding mechanism further includes a fixing member, which is pivotally connected to the connecting seat, the rotating member is connected to the fixing member, and the connecting rod is detachably engaged with the fixing member.

[0017] Specifically, the rotating member and the fixing member are detachably engaged. The rotating member has a connecting portion extending toward the fixing member. The fixing member has a mounting groove corresponding to the connecting portion. The connecting portion is inserted into the mounting groove for engagement.

[0018] The stroller according to an embodiment of this application includes a connecting seat, a rider connector connected to a rider, a front foot connector connected to a front foot, a rear foot connector connected to a rear foot and pivotally connected to the front foot connector, the rider connector being connected to the connecting seat, the front foot connector being pivotally connected to the rider connector, the rear foot connector being pivotally connected to the front foot connector, the rear foot connector being foldable and unfoldable relative to the front foot connector, and further including a folding mechanism as described in any of the above embodiments.

[0051] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0052] The front guard 60 can be any type of guard that restrains the infant or toddler on the seat of the stroller 100. For example, taking a tray as a specific embodiment, the stroller 100 of this application will be described in detail below:

[0053] like Figure 1-8As shown, the stroller 100 of this application includes a connecting seat 20, a handlebar connector 30 connected to a handlebar, a front leg connector 40 connected to a front leg, a rear leg connector 50 connected to a rear leg, and a tray pivotally connected to the connecting seat 20. The handlebar connector 30 is connected to the connecting seat 20, the front leg connector 40 is pivotally connected to the handlebar connector 30, and the rear leg connector 50 is pivotally connected to the front leg connector 40. The rear leg connector 50 is foldable and unfoldable relative to the front leg, that is, the rear leg is foldable and unfoldable relative to the front leg, thereby making the stroller 100 of this application a foldable stroller 100. The stroller 100 of this application also includes a folding mechanism 10, which enables the tray to be folded and unfolded synchronously with the stroller 100.

[0054] The following continues to combine Figures 1-15 A further detailed description is provided of the folding mechanism 10 of this application and the stroller 100 having the folding mechanism:

[0055] Combination such as Figures 4-11 As shown, the folding mechanism 10 of the stroller 100 of this application includes a rotating member 11. Taking the front guard 60 as a tray as an example, connecting rods 61 extend from both ends of the tray. The rotating member 11 is pivotally connected to the connecting seat 20. The connecting rods 61 of the tray and the rotating member 11 are detachably engaged. The tray and the rotating member 11 are pivotally connected. The rotating member 11 rotates to drive the tray to unfold or fold. The rotating member 11 has a first extension 112. The connecting seat 20 has a first connecting post 21. The folding mechanism 10 has an elastic member 12. One end of the elastic member 12 is connected to the first extension 112, and the other end is connected to the first connecting post 21.

[0056] During the unfolding process of the stroller 100, the rear legs unfold relative to the front legs in a clockwise direction. The unfolding of the rear legs causes the rear leg connector 50 to unfold synchronously. During the unfolding process, the rear leg connector 50 needs to overcome the force of the elastic member 12. The rear leg connector 50 abuts against the first extension 112 of the rotating member 11. Overcoming the force of the elastic member 12, it pushes the rotating member 11 to rotate counterclockwise. The counterclockwise rotation of the rotating member 11 causes the tray to unfold, thus realizing that the tray unfolds synchronously with the unfolding of the stroller 100.

[0057] During the folding process of the stroller 100, the rear legs fold relative to the front legs. The folding of the rear legs causes the rear leg connector 50 to fold synchronously. During the folding process, the rear leg connector 50 disengages from the first extension 112, and the rotating member 11 is no longer supported by the rear leg connector 50. The elastic member 12 returns to its original length and pulls the first extension 112 to make the rotating member 11 rotate clockwise. The clockwise rotation of the rotating member 11 causes the tray to fold, thus realizing that the tray folds automatically along with the folding of the stroller 100.

[0058] According to the folding mechanism 10 of the stroller 100 in this application embodiment, by providing a rotating member 11 and an elastic member 12, the tray can be unfolded and automatically folded. When the stroller 100 is unfolded, the rear leg connector 50 pushes the first extension 112, causing the rotating member 11 to rotate counterclockwise relative to the connecting seat 20. The counterclockwise rotation of the rotating member 11 drives the tray, which is engaged with it, to unfold and rotate counterclockwise, enabling the tray and stroller 100 to unfold synchronously, making the unfolding smoother and the operation more convenient. After the stroller 100 is unfolded, the rear leg connector 50 can abut against and support the rotating member 11, and the elastic member 12 connects to the first extension 112. The first connecting post 21 and the 12 can limit the first limiting part, preventing the rotating part 11 from wobbling unstablely, further improving the stability of the rotating part 11, and thus improving the stability of the tray when it is unfolded; when the stroller 100 is folded, the rear foot connecting part 50 disengages from the first extension part 112, and the rotating part 11 is no longer supported by the rear foot connecting part 50. At this time, the elastic part 12 returns to its original length, and the elastic part 12 drives the rotating part 11 to rotate clockwise. The clockwise rotation of the rotating part 11 drives the tray to fold. By setting the elastic part 12, the automatic folding of the tray is realized, and the folding is smoother, improving the convenience of use.

[0059] like Figures 1-7 and Figures 10-11 As shown, in some embodiments, the rear foot connector 50 has a bent portion 51 that bends toward the rotating member 11. During the unfolding process of the rear foot connector 50, the bent portion 51 abuts against the first extension portion 112 of the rotating member 11. During the retraction process of the rear foot connector 50, the bent portion 51 disengages from the first extension portion 112.

[0060] Specifically, during the unfolding process of the rear leg connector 50, its bent portion 51 contacts the first extension portion 112 surface-to-surface. The bent portion 51 pushes the rotating component 11 to rotate counterclockwise, thereby unfolding the plate. The bent portion 51 also supports the rotating component 11 to ensure the stability of the plate during unfolding. During the retraction process of the rear leg connector 50, its bent portion 51 disengages from the contact with the first extension portion 112. In this way, by providing the bent portion 51, the rear leg connector 50 can easily push the rotating component 11 to rotate, and the bent portion 51 and the first extension portion 112 are in surface-to-surface contact, which can support the rotating component 11 and limit the first extension portion 112 to prevent it from shaking, thereby improving the stability of the rotating component 11 and the plate.

[0061] like Figure 5 and Figure 15 As shown, specifically, the rotating member 11 further includes: a body 111 and a second extension 113. The first extension 112 and the second extension 113 are provided on the side of the body 111 away from the connecting seat 20. The first extension 112 and the second extension 113 are connected, and the first extension 112 and the second extension 113 extend in opposite directions.

[0062] It should be noted that the main body 111 has a plate-like structure. The side of the main body 111 closest to the connecting seat 20 is connected to the connecting seat 20. The side of the main body 111 away from the connecting seat 20 has a first extension 112 and a second extension 113 protruding away from the connecting seat 20. The first extension 112 and the second extension 113 are connected and extend in opposite directions. The first extension 112 extends clockwise outward from the main body 111 and has a cantilever-like structure. The second extension 113 is formed circumferentially around the main body 111, with its outer wall partially overlapping the outer periphery of the main body 111. The second extension 113 extends counterclockwise, partially extending out of the main body 111. This design simplifies the structure of the rotating member 11 and facilitates its installation. The first extension 112 protruding from the main body 111 allows the bending portion 51 to push the first extension 112, causing the rotating member 11 to rotate.

[0063] like Figure 14 and 15 As shown, the first extension 112 further has a first contact surface 1121, which is located on the inner side of the first extension 112. During the unfolding process of the rear foot connector 50, the bent part 51 contacts the first contact surface 1121. During the retraction process of the rear foot connector 50, the bent part 51 disengages from the first contact surface 1121.

[0064] Specifically, the bent portion 51 is positioned opposite to the first contact surface 1121. When the rear leg connector 50 unfolds, it rotates clockwise, and the bent portion 51 rotates toward the first extension 112, pushing against the first contact surface 1121 of the first extension 112 to drive the rotating member 11 to rotate counterclockwise. When the rear leg connector 50 retracts, the bent portion 51 disengages from the first contact surface 1121, and the two no longer contact each other, thus avoiding interference with the clockwise rotation of the rotating member 11. This arrangement allows the rear leg connector 50 and the first extension 112 to contact each other surface-to-surface, so that the clockwise rotation of the rear leg connector 50 drives the rotating member 11 to rotate counterclockwise, making the unfolding process smoother and facilitating the automatic retraction of the plate.

[0065] like Figure 9 and Figure 14 As shown, the first extension 112 further includes a second connecting post 1122, which protrudes from the side of the first extension 112 near the connecting seat 20. The two ends of the elastic member 12 are connected to the first connecting post 21 and the second connecting post 1122, respectively.

[0066] It should be noted that a second connecting post 1122 protruding toward the connecting seat 20 is provided on the side of the first extension 112 near the connecting seat 20. The second connecting post 1122 is located at the free end of the first extension 112. The first connecting post 21 protrudes from the side of the connecting seat 20 away from the plate and extends toward the rear foot connector 50. One end of the elastic member 12 is connected to the second connecting post 1122 on the first extension 112, and the other end is connected to the first connecting post 21 on the connecting seat 20.

[0067] This configuration allows the first extension 112 to be connected to the connecting seat 20, so that when the plate is unfolded, the elastic element 12 can limit the first extension 112, preventing one end of the first extension 112 of the rotating member 11 from wobbling, thereby improving the stability of the rotating member 11. In addition, the first connecting post 21 is fixedly installed, which can fix one end of the elastic element 12. When the rear foot connecting member 50 is closed, the elastic element 12 drives the first extension 112 to rotate clockwise, thereby realizing the automatic folding of the plate.

[0068] like Figure 5 and Figure 15 As shown, specifically, the second extension 113 has a second contact surface 1131, which is located on the outer side of the second extension 113. A locking block 31 corresponding to the second extension 113 is protruding from the rider connector 30. When the front guard 60 is unfolded into a horizontal position, the locking block 31 abuts against the second contact surface 1131.

[0069] It should be noted that a locking block 31 is provided on the side of the driver connector 30 away from the connector seat 20. The locking block 31 extends in the direction away from the connector seat 20. When the rotating member 11 rotates counterclockwise, the second extension 113 gradually approaches the locking block 31. When the tray is unfolded, the second extension 113 cooperates with the locking block 31. The locking block 31 pushes against the second contact surface 1131 of the second extension 113 to limit the second extension 113. It abuts against the first extension 112 from the outer edge of the connector seat 20 to limit the counterclockwise rotation of the rotating member 11. At the same time, the limiting groove 115 also further limits the counterclockwise rotation of the rotating member 11.

[0070] In this way, by setting the locking block 31 and making it abut against the second contact surface 1131 of the second extension 113, the clockwise rotation of the rotating member 11 can be restricted. The locking block 31 can provide support and lock the plate. When the rear foot connector 50 is closed, the locking block 31 disengages from the second contact surface 1131 of the second extension 113, and the rotating member 11 can automatically retract clockwise, thereby driving the plate to retract. The locking block 31 and the bent part 51 push against the rotating member 11 from opposite directions to better limit the rotation of the rotating member 11, thereby preventing the plate from moving and improving the stability of the plate in the unfolded state.

[0071] like Figure 5 As shown, in some embodiments, the connection between the first extension 112 and the second extension 113 defines a receiving area, and an abutment 114 is provided in the receiving area. The abutment 114 protrudes from the side of the body 111 away from the connecting seat 20, and the abutment 114 fits against the first extension 112 and the second extension 113.

[0072] Specifically, an arc-shaped placement area is defined at the connection between the first extension 112 and the second extension 113, within which an abutment 114 is provided. The abutment 114 is constructed as a cylinder, with one end connected to the body 111 and the other end extending away from the connecting seat 20. The abutment 114 is made of rubber material, for example, it can be a wear-resistant washer sleeve. During the unfolding of the rear leg, the rear leg connector 50 rotates clockwise. During the rotation, the bending part 51 first pushes against the abutment 114. The abutment 114 can buffer part of the thrust and reduce the load, which can reduce the rotation angle of the rear leg connector 50. When the bending part 51 rotates to the first extension 112, its load is reduced, and it can push against the first extension 112 more gently.

[0073] In this way, the abutment part 114 can protect the rotating part 11, so that when the rear foot connector 50 rotates clockwise, it first pushes against the abutment part 114 and then against the first extension part 112, avoiding the bending part 51 directly pushing against the first extension part 112, causing it to wear out or break, thus improving the safety of the first extension part 112.

[0074] like Figures 9-11 As shown, in some embodiments, the folding mechanism 10 further includes a support piece 70. The support piece 70 has a bent structure, with one end fixedly connected to the connecting seat 20 and the other end pivotally connected to the rotating member 11. The support piece 70 includes a fixing portion 71, which bends and extends toward the rotating member 11 to form a support portion 72. The fixing portion 71 is fixedly connected to the connecting seat 20, and the support portion 72 is pivotally connected to the rotating member 11. The support portion 72 presses against the side of the body 111 away from the connecting seat 20 and is pivotally connected to the rotating member 11. The support piece 70 connects the rotating member 11 and the connecting seat 20, which can fix the rotating member 11 to the connecting seat 20, limit the position of the rotating member 11, prevent the rotating member 11 from loosening, and improve the stability of the connection between the rotating member 11 and the connecting seat 20.

[0075] like Figure 5 and Figure 15 As shown, the rotating member 11 is further provided with a limiting groove 115, and the support part 72 is provided in the limiting groove 115. When the front guard 60 is unfolded into a horizontal position, the support part 72 abuts against one side of the groove wall of the limiting groove 115; when the front guard 60 is fully retracted, the support part 72 abuts against the other side of the groove wall of the limiting groove 115.

[0076] Specifically, a limiting groove 115 is provided on the main body 111, and its structure is a fan-shaped groove. The limiting groove 115 cooperates with the support part 72, and the fan-shaped groove can limit the rotation angle of the support part 72. When the plate is unfolded and in a horizontal position, the support part 72 abuts against one side of the groove wall of the limiting groove 115; when the plate is fully closed, the support part 72 abuts against the other side of the groove wall of the limiting groove 115.

[0077] It should be noted that by setting the limiting groove 115, the support part 72 can be limited, so that when the tray is unfolded and used, if it is subjected to a pulling force in the unfolding direction, the contact between the groove wall of the limiting groove 115 and the support part 72 will prevent the tray from rotating in the unfolding direction, thus ensuring the stability of the tray when unfolded and used. By limiting the support part 72 with the limiting groove 115, when the tray is fully folded, if it is subjected to pressure in the folding direction, the contact between the groove wall of the limiting groove 115 and the support part 72 will prevent the tray from rotating in the folding direction, thus preventing the tray from interfering with the normal operation of other mechanisms of the stroller 100.

[0078] like Figure 3 and Figure 12 As shown, in some embodiments, the folding mechanism 10 further includes a fixing member 80, which is pivotally connected to the connecting seat 20. The rotating member 11 is connected to the fixing member 80, and the connecting rod 61 is detachably engaged with the fixing member 80.

[0079] Specifically, a fixing member 80 is provided between the connecting rod 61 of the plate and the rotating part 11. The fixing member 80 is pivotally connected to the connecting seat 20. The rotating part 11 is connected to the fixing member 80. The connecting rod 61 of the plate and the fixing member 80 are detachably engaged. The fixing member 80 has an engagement hole, and the connecting rod 61 of the plate has a engagement protrusion corresponding to the engagement hole. The engagement protrusion is inserted into the engagement hole to engage and fix the plate with the fixing member 80, directly realizing the detachable engagement connection between the plate and the fixing member 80, and indirectly realizing the detachable engagement connection between the plate and the rotating part 11. This effectively improves the stability of the transmission between the plate, the rotating part 11 and the fixing member 80 of the plate in this application, as well as the convenience of installation and maintenance.

[0080] like Figures 13-14 As shown, specifically, the rotating member 11 and the fixing member 80 are detachably engaged. The rotating member 11 has a connecting portion 116 extending toward the fixing member 80. The fixing member 80 is provided with a mounting groove 81 corresponding to the connecting portion 116. The connecting portion 116 is inserted into the mounting groove 81 for engagement.

[0081] It should be noted that the rotating member 11 and the fixed member 80 are detachably engaged by the connecting part 116 being inserted into the mounting groove 81. The connecting part 116 is formed on the rotating member 11 and extends toward the fixed member 80. The mounting groove 81 is formed on the fixed member 80 and is recessed inward. The mounting groove 81 and the connecting part 116 have the same shape and are positioned opposite each other. The connecting part 116 is inserted into the mounting groove 81 for engagement. Alternatively, the connecting part 116 can be provided on the fixed member 80, and the mounting groove 81 can be provided on the rotating member 11.

[0082] In this way, the engagement of the connecting part 116 and the mounting groove 81 allows for a detachable engagement between the rotating part 11 and the fixed part 80, making the transmission more stable and reliable, the structure simpler, the practicality stronger, and the assembly and disassembly difficulty reduced, making assembly and disassembly more convenient and quick.

[0083] The stroller 100 according to an embodiment of this application includes a connecting seat 20, a handlebar connector 30 connected to a handlebar, a front foot connector 40 connected to a front foot, a rear foot connector 50 connected to a rear foot, and a front guard 60 pivotally connected to the connecting seat 20. The handlebar connector 30 is connected to the connecting seat 20, the front foot connector 40 is pivotally connected to the handlebar connector 30, and the rear foot connector 50 is pivotally connected to the front foot connector 40. The rear foot connector 50 can be folded and unfolded relative to the front foot connector 40. It also includes the folding mechanism 10 in the above embodiment.

[0084] Since the rotating component 11 is pivotally connected to the connecting seat 20, the tray is detachably engaged with the rotating component 11 via its connecting rod 61. The rotating component 11 has a protruding first extension 112. During the unfolding process, the rear leg connecting component 50 abuts against the first extension 112 of the rotating component 11. Therefore, when the stroller 100 unfolds, the rear leg connecting component 50 will drive the rotating component 11 to rotate relative to the connecting seat 20 by abutting against the first extension 112. The rotation of the rotating component 11 will drive the tray engaged with it to rotate relative to the connecting seat 20, thereby causing the rear leg connecting component 50 to drive the tray to rotate relative to the connecting seat 20 and unfold by abutting against the first extension 112. The unfolding of the tray is synchronized with the unfolding of the stroller 100, and the unfolding is smooth and easy to operate. Since the unfolded tray is supported by the abutting between the rear leg connecting component 50 and the first extension 112, the tray can be stably in the unfolded state.

[0085] During the folding process of the stroller 100, the rear leg connector 50 disengages from the first extension 112, the rotating member 11 is no longer supported by the rear leg connector 50, the elastic member 12 returns to its original length, and pulls the first extension 112 to make the rotating member 11 rotate clockwise. The clockwise rotation of the rotating member 11 drives the tray to fold, realizing that the tray automatically folds along with the stroller 100, making the folding process smoother and the operation more convenient. In summary, the folding mechanism 10 of this application and the stroller 100 having the folding mechanism 10 have a simple structure and are convenient and smooth to unfold and fold.
