[0053] The following describes the embodiments of the present invention in detail with reference to the accompanying drawings.

[0054] like Figure 1-18 A foldable baby stroller is shown, comprising a baby stroller body 1 having an unfolded state and a folded state, and further comprising a lateral folding device 2 connected to the baby stroller body 1. The lateral folding device 2 comprises a lateral support assembly 21 connected to the baby stroller body 1. When the baby stroller body 1 is in the folded state, the lateral support assembly 21 is retracted to allow the baby stroller body 1 to retract laterally.

[0055] The stroller body 1 includes a first body 11 and a second body 12 connected to the first body 11. The lateral support assembly 21 includes a first locking device 211 that supports the first and second bodies 11 and keeps them in an unfolded state.

[0056] The first locking device 211 is in a locked state, so that the first body 11 and the second body 12 are fixed in a laterally expanded state. When the first locking device 211 is in an unlocked state, the first body 11 approaches the second body 12 or the first body 11 and the second body 12 approach each other in both directions, so that the stroller body 1 contracts laterally.

[0057] The present invention adds a lateral folding device 2 to the stroller main body 1, so that the stroller can be further folded by contracting laterally in the folded state, thereby further reducing the volume of the foldable stroller. It is not only convenient for users to carry and travel, but also meets the size restrictions of airline boarding luggage, thereby improving the portability and practicality of the stroller.

[0058] The lateral folding device 2 is provided on the main body 1 of the baby carriage, so that the baby carriage can be retracted laterally in the folded state, thereby further reducing the size of the baby carriage. This arrangement is not only convenient for users to carry and travel, but also meets the size restrictions of airline carry-on luggage, thereby greatly improving the portability and practicality of the baby carriage. Specifically, the side folding device 2 includes a side support assembly 21 connected to the main body 1 of the baby carriage. When the main body 1 of the baby carriage is in the folded state, the side support assembly 21 is retracted, so that the main body 1 of the baby carriage can be retracted laterally and further folded, thereby achieving a more compact folding effect. This arrangement makes the volume of the baby carriage after lateral retraction even smaller, which is not only convenient for users to carry when going out, but also enables the baby carriage to meet the size requirements of airlines for carry-on items. In addition, the lateral retraction arrangement also makes the baby carriage take up less space when stored at home, thereby improving the utilization rate of home space. Furthermore, the arrangement of the side folding device 2 makes it convenient for users to unfold and fold The process of folding the stroller is smoother and more convenient, and the complexity of folding the stroller is simplified. This setting not only improves the user's operating experience, but also reduces the jamming or failure that may occur during the folding process, thereby increasing the durability of the stroller. Furthermore, the utility model divides the stroller body 1 into a first body 11 and a second body 12, and sets a first locking device 211 between the two. By locking the first locking device 211, the first body 11 and the second body 12 are placed in and fixed in the unfolded state. When the stroller is not needed, the unfolded state of the first body 11 and the second body 12 is released by unlocking the first locking device 211, so that the first body 11 and the second body 12 can be close to each other, thereby realizing lateral contraction of the stroller. This setting enables the stroller body 1 to flexibly maintain the unfolded state or realize lateral contraction, which not only simplifies the folding process of the stroller, but also ensures the stability of the stroller in the unfolded state, further improving the convenience and safety of the use of the stroller.

[0059] Further, such as Figure 1-18A foldable baby carriage is shown, wherein the first locking device 211 includes a first connecting rod 2111, a connecting assembly 2110 rotatably connected to one end of the first connecting rod 2111, and a first locking member 2113 movably connected to the connecting assembly 2110 near one end of the first connecting rod 2111, the other end of the first connecting rod 2111 is rotatably connected to the first main body 11, and the other end of the connecting assembly 2110 is rotatably connected to the second main body 12, when the first locking device 2111 is in a locked state, the first locking member 2113 fixes the relative positions of the first connecting rod 2111 and the connecting assembly 2110.

[0060] The present invention ensures that the stroller body 1 can be firmly locked in the expanded or laterally retracted state by arranging the first connecting rod 2111, the connecting assembly 2110 and the first locking member 2113 in the first locking device 211. When the stroller body 1 is in the expanded state or the laterally retracted state, the first locking member 2113 can fix the relative position between the first connecting rod 2111 and the connecting assembly 2110, thereby ensuring that the stroller body 1 can be firmly locked regardless of whether it is in the expanded state or the laterally retracted state. This arrangement not only ensures the safety of the stroller when in use, but also makes it difficult for the stroller to be accidentally expanded due to external force after being laterally retracted, thereby further improving the portability.

[0061] Further, such as Figure 1-18 In the foldable baby stroller shown, when the first body 11 and the second body 12 are in the unfolded state, the first locking member 2113 is locked with the first connecting rod 2111.

[0062] The utility model provides a first connecting rod 2111 and a first locking member 2113 in the first locking device 211. When the first body 11 and the second body 12 are in the unfolded state, the first locking member 2113 and the first connecting rod 2111 are locked together, thereby ensuring the stability of the baby carriage body 1 in the unfolded state, effectively preventing structural loosening or folding failure caused by unexpected external forces during use, and improving the safety and reliability of the baby carriage.

[0063] Further, such as Figure 1-18 The foldable baby carriage shown in the figure has a first locking member 2113 that is rotatably connected to the connecting component 2110 near one end of the first connecting rod 2111. The connecting component 2110 is provided with a limiting end 21121 and includes a second connecting rod 2112.

The first connecting rod 2111 is provided with a limiting surface 21112 and the limiting surface 21112 corresponds to the limiting end 21121 and abuts against the limiting end 21121.

[0064] The utility model sets a connecting component 2110 and a first connecting rod 2111 in the first locking device 211. When the first body 11 and the second body 12 are in the unfolded state, the first connecting rod 2111 and the second connecting rod 2112 form a certain angle, and the limiting end 21121 of the connecting component 2110 is abutted against the limiting surface 21112 of the first connecting rod 2111, which effectively prevents loosening in the unfolded state and ensures the stability of the stroller body 1.

[0065] Further, such as Figure 1-18 A foldable baby stroller is shown, wherein the connecting assembly 2110 includes a second connecting rod 2112 and a connecting shell 2115 fixedly connected to the second connecting rod 2112, the connecting assembly 2110 is provided with a limiting end 21121 on one side of the connecting shell 2115, the second connecting rod 2112 is rotatably connected to the second main body 12, one end of the connecting shell 2115 is respectively rotatably connected to the first connecting rod 2111 and movably connected to the first locking member 2113, the first locking member 2113 is provided with a clamping end 21131 at one end close to the first connecting rod 2111, the first connecting rod 2111 is provided with an avoidance groove 21113 located near one end of the connecting shell 2115 and a first clamping groove 21111 abutting against the clamping end 21131;

[0066] When the engaging end 21131 is disengaged from the first engaging groove 21111 , the stroller body 1 contracts laterally, and the avoiding groove 21113 cooperates with the engaging end 21131 to avoid or lock.

[0067] The present invention can effectively fix the relative position between the first connecting rod 2111 and the connecting assembly 2110 by arranging the engagement end 21131 in the first locking device 211 and cooperating with the first engagement groove 21111, thereby ensuring the stability and reliability of the baby stroller body 1 in the unfolded state; further, by arranging the avoidance groove 21113 on the first connecting rod 2111, the lateral contraction process of the baby stroller can avoid possible structural interference, thereby enabling the baby stroller to achieve a tighter lateral contraction effect; further, in other embodiments, the avoidance groove 21113 can also be buckled with the engagement end 21131, thereby increasing the locking and further stabilizing the lateral contraction state of the baby stroller.

[0068] Further, such as Figure 1-18The first connecting rod 2111 and the first locking piece 2113 are rotatably connected to the swing cavity 21122, and the first locking device 211 further comprises a first reset assembly 2114 located in the swing cavity 21122 and used for resetting the first locking piece 2113.

[0069] The first connecting rod 2111 and the first locking piece 2113 are rotatably connected to the swing cavity 21122, and the first locking device 211 further comprises a first reset assembly 2114 located in the swing cavity 21122 and used for resetting the first locking piece 2113.

[0070] Further, as shown in Figure 1-18 The first connecting rod 2111 and the first locking piece 2113 are rotatably connected to the swing cavity 21122, and the first locking device 211 further comprises a first reset assembly 2114 located in the swing cavity 21122 and used for resetting the first locking piece 2113.

[0071] The first connecting rod 2111 and the first locking piece 2113 are rotatably connected to the swing cavity 21122, and the first locking device 211 further comprises a first reset assembly 2114 located in the swing cavity 21122 and used for resetting the first locking piece 2113.

[0072] Further, such as Figure 1-18 A foldable baby stroller is shown, wherein the baby stroller body 1 includes a first body 11 and a second body 12 connected to the first body 11, the lateral support assembly 21 includes a support assembly 212 that supports the first and second bodies 11, 12 and keeps them in an unfolded state, and the first locking device 211 is used to lock or unlock the support assembly 212;

[0073] The support assembly 212 includes a first support rod 2121 and a second support rod 2122 connected to the first body 11 and the second body 12 respectively. The first support rod 2121 and the second support rod 2122 are rotatably connected and arranged in an X shape.

[0074] The present invention divides the stroller body 1 into a first body 11 and a second body 12, and provides a support assembly 212 and a first locking device 211 capable of locking and unlocking the support assembly 212 between the two. By unfolding the support assembly 212, the first body 11 and the second body 12 are in the unfolded state. At the same time, the first locking device can lock the support assembly 212 in the unfolded state to ensure that the first body 11 and the second body 12 can be stably fixed in the unfolded state. When the stroller is not needed, the first locking device 211 is unlocked to release the unfolded state of the support assembly 212, so that the first body 11 and the second body 12 can be moved closer to each other, thereby achieving lateral contraction of the stroller. This arrangement enables the stroller body 1 to flexibly maintain the unfolded state or achieve lateral contraction, which not only simplifies the folding process of the stroller, but also ensures the stability of the stroller in the unfolded state, further improving the convenience and safety of the stroller.

[0075] Furthermore, the support assembly 212 in the present invention includes a first support rod 2121 and a second support rod 2122, and the two are connected in an X-shaped rotation, ensuring the smoothness of the stroller body 1 during the unfolding and lateral contraction process. First, the X-shaped setting enables the first support rod 2121 and the second support rod 2122 to form a stable support structure in the unfolded state. This structure not only provides sufficient supporting force to maintain the stability of the stroller body 1 during use, but also because the two support rods are rotatable at the middle intersection, this provides the necessary space for the support rods to move when folded. When the stroller body 1 needs to be converted from the unfolded state to the lateral contraction state, the first support rod 2121 and the second support rod 2122 can rotate around their intersection, thereby achieving compact stacking, ensuring that the stroller can effectively reduce the space occupied.

[0076] Further, such as Figure 1-18A folding baby carriage is shown, wherein the first body 11 is provided with a first connecting rod 111, the second body 12 is provided with a second connecting rod 121, the support assembly 212 is further provided with a third support rod 2123 rotatably connected to one end of the first support rod 2121, and a fourth support rod 2124 rotatably connected to one end of the second support rod 2122, the other end of the first support rod 2121 is movably connected to the first connecting rod 111, the other end of the third support rod 2123 is movably connected to the second connecting rod 121, the first support rod 2121 and the second support rod 2122 are symmetrically arranged, and the third support rod 2123 and the fourth support rod 2124 are symmetrically arranged.

[0077] The present invention adds a third support rod 2123 rotatably connected to one end of the first support rod 2121, a fourth support rod 2124 rotatably connected to one end of the second support rod 2122, the first connecting rod 111 and the second connecting rod 121 to the support assembly 212. This arrangement enables the various support rods to work together when the baby stroller is unfolded and folded, thereby ensuring the stability of the baby stroller body in the unfolded state. Furthermore, the present invention arranges the first support rod 2121 and the second support rod 2122 to be symmetrically arranged, the third support rod 2123 and the fourth support rod 2124 to be symmetrically arranged, and the entire support assembly 212 forms an X-shaped structure after unfolding. This symmetrical arrangement not only can It can evenly distribute the pressure on the baby carriage when in use, and can also ensure that the baby carriage can maintain good balance under various terrain conditions. When the baby carriage is in use, the X-shaped support assembly 212 can effectively support both sides of the baby carriage, ensuring the stability of the baby carriage body, and also making the baby carriage more stable during driving; further, after the support assembly 212 is retracted, the support assembly 212 is located on the side where the third support rod 2123 is connected to the first support rod 2121, and on the side where the fourth support rod 2124 is connected to the second support rod 2122 to form a W-shaped arrangement, so that the volume of the entire support assembly 212 after folding is greatly reduced, which is not only convenient for storage, but also convenient for carrying.

[0109] The implementation of this embodiment is as follows:

[0110] Example 1:

[0111] See also Figures 1-6 In this embodiment, the foldable stroller is folded sideways by unlocking the first locking device 211. The specific steps are as follows: the first locking device 211 includes a first connecting rod 2111, a connecting assembly 2110, and a first locking member 2113. When the first locking device 211 is in a locked state, the first locking member 2113 fixes the relative position of the first connecting rod 2111 and the connecting assembly 2110. When the first locking device 211 is unlocked, the user presses the first locking member 2113 to disengage the engaging end 21131 of the first locking member 2113 from the first engaging groove 21111 of the first connecting rod 2111. At this time, the first support rod 2121 and the second support rod 2122 can rotate around their central connection intersection, thereby allowing the first body 11 and the second body 12 to move closer to each other and retract. When the first body 11 and the second body 12 reach the predetermined retracted position, the engaging end 21131 on the first locking member 2113 cooperates with the avoidance groove 21113 on the first connecting rod 2111 to lock the support assembly 212 in the lateral retracted state, thereby realizing the lateral retraction process of the folding stroller.

[0112] During the deployment step, the first locking member 2113 is pressed, causing the engaging end 21131 of the first locking member 2113 to disengage from the avoidance groove 21113 of the first linkage rod 2111. At this point, the first support rod 2121 and the second support rod 2122 can rotate about their central intersection, thereby allowing the first body 11 and the second body 12 to move away from each other, thereby returning to the deployed state. When reaching the deployed position, the support assembly 212 forms a stable X-shaped support structure, and the engaging end 21131 of the first locking member 2113 engages with the first engaging groove 21111 of the first linkage rod 2111, thereby locking the stroller body 1 in the deployed state.

[0113] Example 2:

[0114] See also Figures 1-9 Compared with the first embodiment, this embodiment further adds a guide assembly 22 and a second locking device 23. The steps for lateral contraction of the folding stroller in this embodiment are as follows: First, the user needs to unlock the first locking device 211. The specific operation is to press the first locking member 2113 so that the engaging end 21131 of the first locking member 2113 is disengaged from the first engaging groove 21111 of the first connecting rod 2111. Then, the user also needs to unlock the second locking device 23. Through the pushing portion 2323, the buckle end 2322 on the pressing block 232 is disengaged from the fixed end 2311 of the fixing seat 231, and then the pressing end 2321 on the pressing block 232 is disengaged from the elastic pressing block 2221, thereby releasing the locking state between the first guide rod 221 and the second guide rod 222. After the first locking device 211 and the second locking device 23 are unlocked, the first support rod 2121 and the second support rod 2122 can rotate about their intermediate intersection, and the first guide rod 221 can slide within the second guide rod 222, causing the first body 11 and the second body 12 to move closer to each other and retract. When the first body 11 and the second body 12 reach the predetermined retracted position, the engaging end 21131 on the first locking member 2113 cooperates with the avoidance groove 21113 on the first linkage rod 2111, locking the support assembly 212 in the lateral retracted state. Subsequently, the buckle end 2322 of the pressure block 232 in the second locking device 23 is pressed against the fixed end 2311 of the fixing seat 231, so that the pressing end 2321 on the pressure block 232 presses the elastic pressing block 2221, thereby locking the relative position between the first guide rod 221 and the second guide rod 222, and realizing the lateral retraction process of the folding baby stroller.

[0115] During the deployment step, the user first needs to press the first locking member 2113 to disengage the engaging end 21131 of the first locking member 2113 from the avoidance groove 21113 of the first linkage rod 2111. Subsequently, the user uses the pushing portion 2323 to separate the snap end 2322 on the pressing block 232 from the fixed end 2311 of the fixing seat 231, thereby causing the pressing end 2321 on the pressing block 232 to disengage from the elastic pressing block 2221. At this point, the first support rod 2121 and the second support rod 2122 can rotate around their central intersection, while the first guide rod 221 can slide freely within the second guide rod 222, thereby allowing the first body 11 and the second body 12 to move away from each other and return to the deployed state. When the support assembly 212 reaches the fully deployed position, it forms a stable X-shaped support structure, and the engaging end 21131 of the first locking member 2113 engages with the first engaging groove 21111 of the first connecting rod 2111, thereby locking the support assembly 212. Next, the buckle end 2322 of the pressing block 232 in the second locking device 23 is pressed against the fixed end 2311 of the fixing seat 231, so that the pressing end 2321 of the pressing block 232 presses against the elastic pressing block 2221, thereby locking the relative position between the first guide rod 221 and the second guide rod 222, thereby ensuring that the stroller body 1 is locked in the deployed state.

[0116] Example 3:

[0117] See also Figures 1-18Compared to the second embodiment, this embodiment further adds a folding handle 154 and a third locking device 151. The steps for folding and laterally retracting the folding handle 154 of the folding stroller in this embodiment are as follows: First, the user needs to slide the second locking member 1512 to the unlocking area, and then press the pressing member 1511 to disengage the first engaging member 1514 and the second engaging member 1515 from the first engaging groove 15411 of the first folding handle 1541 and the second engaging groove 15421 of the second folding handle 1542, respectively, thereby achieving folding of the folding handle 154 in the direction of the first body 11 and the second body 12. Then, the user needs to unlock the first locking device 211. The specific operation is to press the first locking member 2113 to disengage the engaging end 21131 of the first locking member 2113 from the first engaging groove 21111 of the first connecting rod 2111. Next, the user also needs to unlock the second locking device 23. The pushing portion 2323 causes the buckle end 2322 of the pressing block 232 to disengage from the fixed end 2311 of the fixing seat 231, thereby causing the pressing end 2321 of the pressing block 232 to disengage from the elastic pressing block 2221, thereby releasing the locking state between the first guide rod 221 and the second guide rod 222. After the folding handle 154 is folded and the first locking device 211 and the second locking device 23 are unlocked, the first support rod 2121 and the second support rod 2122 can rotate around their middle intersection. At the same time, the first guide rod 221 can slide within the second guide rod 222, and the folding handle 154 will fold toward the first and second bodies 11 and 12 as the first and second bodies 11 and 12 shrink laterally, causing the first and second bodies 11 and 12 to shrink closer to each other. When the first and second bodies 11, 12 reach the predetermined retracted position, the engaging end 21131 of the first locking member 2113 engages with the avoidance groove 21113 of the first linkage rod 2111, locking the support assembly 212 in the lateral retracted state. Subsequently, the buckle end 2322 of the pressure block 232 in the second locking device 23 is pressed against the fixed end 2311 of the fixing seat 231, causing the pressing end 2321 of the pressure block 232 to press against the elastic pressing block 2221, thereby locking the relative position between the first guide rod 221 and the second guide rod 222, and completing the lateral retraction process of the foldable stroller.

[0118] During the deployment step, the user first presses the first locking member 2113, disengaging the engaging end 21131 of the first locking member 2113 from the escape groove 21113 of the first linkage rod 2111. Subsequently, the user uses the pushing portion 2323 to separate the snap end 2322 of the pressure block 232 from the fixed end 2311 of the fixing seat 231, thereby disengaging the pressing end 2321 of the pressure block 232 from the elastic pressing block 2221. At this point, the first support rod 2121 and the second support rod 2122 are able to rotate about their central intersection, while the first guide rod 221 is able to slide freely within the second guide rod 222, allowing the first and second bodies 11, 12 to move away from each other and return to the deployed state. During the deployment of the first and second bodies 11, 12, the first and second folding handles 1541, 1542 automatically move to the deployed position as the first and second bodies 11, 12 deploy. When the fully unfolded state is reached, the first engaging member 1514 will automatically be inserted into the first engaging groove 15411, and the second engaging member 1515 will automatically be inserted into the second engaging groove 15421, so that the folding handle 154 remains in the unfolded state, and the second locking member 1512 will automatically reset to the locking area under the action of the second reset component 1516, thereby locking the pressing member 1511. At the same time, the support component 212 forms a stable X-shaped support structure, and the engaging end 21131 of the first locking member 2113 cooperates with the first engaging groove 21111 of the first connecting rod 2111, thereby locking the support component 212. Next, the buckle end 2322 of the pressure block 232 in the second locking device 23 is pressed against the fixed end 2311 of the fixing seat 231, so that the pressing end 2321 on the pressure block 232 presses the elastic pressing block 2221, thereby locking the relative position between the first guide rod 221 and the second guide rod 222, ensuring that the unfolded state of the stroller body 1 is locked.

[0119] Example 4:

[0120] See also Figures 1-18In this embodiment, the folding and lateral contraction steps of the folding handle 154 of the folding stroller are similar to those of Example 3. The difference is that compared with Example 3, this embodiment further adds a first handle connecting member 152 rotatably connected to one end of the first body 11 and a second handle connecting member 153 rotatably connected to one end of the second body 12. The folding handle 154 is connected to the first handle connecting member 152 and the second handle connecting member 153 respectively. When folding the stroller, the second locking member 1512 is first slid to the unlocking area, and then the pressing member 1511 is pressed to fold the folding handle 154 toward the first body 11 and the second body 12. At the same time, the first handle connecting member 152 can rotate toward the first body 11 around the end rotatably connected to the first body 11, and the second handle connecting member 153 can rotate toward the second body 12 around the end rotatably connected to the second body 12, so that the entire body consisting of the first handle connecting member 152, the second handle connecting member 153, the folding handle 154, and the third locking device 151 can be folded toward the first body 11 and the second body 12. In the unfolding step, the pressing member 1511 is pressed to restore the first handle connecting member 152 and the second handle connecting member 153 to the unfolded state.

[0121] Embodiment 5:

[0122] See also Figures 1-18 In this embodiment, the folding and lateral contraction steps of the folding handle 154 of the folding stroller are similar to those in Example 4. The difference is that the connecting assembly 2110 in this embodiment includes a second connecting rod 2112 rotatably connected to the second main body 12 and a connecting shell 2115 fixedly connected to the second connecting rod 2112, and the second connecting rod 2112 and the connecting shell 2115 are connected in a detachable manner. When the first locking device 211 needs to be repaired, this arrangement facilitates maintenance personnel to quickly disassemble and install the connecting shell 2115 without disassembling the entire connecting assembly 2110, thereby simplifying the maintenance and repair process.

[0123] Example 6:

[0124] See also Figures 1-18In this embodiment, the folding and lateral contraction steps of the folding handle 154 of the folding stroller are similar to those in Example 5, except that in this embodiment, a first connecting rod 111 movably connected to the first main body 11 and a second connecting rod 121 movably connected to the second main body 12 are further added, and the support assembly 212 is further provided with a third support rod 2123 rotatably connected to one end of the first support rod 2121, and a fourth support rod 2124 rotatably connected to one end of the second support rod 2122. The other end of the first support rod 2121 is movably connected to the first connecting rod 111, and the other end of the third support rod 2123 is movably connected to the second connecting rod 121. The first support rod 2121 and the second support rod 2122 are symmetrically arranged, and the third support rod 2123 and the fourth support rod 2124 are symmetrically arranged.

[0125] When the stroller is folded and laterally retracted, the support assembly 212 is located on the side where the third support rod 2123 is connected to the first support rod 2121, and on the side where the fourth support rod 2124 is connected to the second support rod 2122, forming a W-shaped arrangement, so that the volume of the entire support assembly 212 is further reduced after folding.

[0126] Embodiment seven:

[0127] See also Figures 1-18 In this embodiment, when the first body 11 and the second body 12 reach the predetermined retraction position, the avoidance groove 21113 is used to avoid the engaging end 21131 on the first locking member 2113, so that the lateral retraction process of the baby carriage can avoid possible structural interference, thereby enabling the baby carriage to achieve a tighter lateral retraction effect.
