[0032] In order to make the technical problems, technical solutions and beneficial effects solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0033] See also Figures 1 to 9 A foldable baby stroller includes a release mechanism 1, a frame body 2, and an armrest assembly 3 hinged to the frame body 2. The release mechanism 1 is respectively connected to the frame body 2 and the armrest assembly 3 and is used to restrict or release the folding of the armrest assembly 3 relative to the frame body 2, and restrict or release the folding of the frame body 2.

[0034] The foldable baby stroller of the present application connects a frame body and an armrest assembly through a lock release mechanism, thereby limiting or releasing the folding of the armrest assembly relative to the frame body, and limiting or releasing the folding of the frame body at the same time, thereby simplifying the folding operation of the baby stroller, solving the problem of complicated folding operation in the prior art, and making the baby stroller more convenient when folding.

[0035] Furthermore, as a preferred embodiment of the present invention but not a limitation thereof, the release mechanism 1 includes a pressing block 11 arranged on the armrest assembly 3, a sliding block 12 arranged in the armrest assembly 3 and abutting against the pressing block 11 along an inclined surface, a connecting member 13 arranged in the armrest assembly 3 and connected to the sliding block 12 by a steel wire rope, a locking member 14 sleeved on the outside of the armrest assembly 3, and a locking groove 15 arranged on the frame body 2 for the locking member 14 to be engaged, a first elastic member 16 is arranged between the pressing block 11 and the inner wall of the armrest assembly 3, a second elastic member 17 is arranged between the connecting member 13 and the frame body 2, and a sliding groove 18 is provided on the armrest assembly 3 for the connecting member 13 to slide through to connect to the locking member 14.

[0036] In this embodiment, the folding restriction and release of the armrest assembly 3 relative to the frame body are realized. When the pressing block is pressed down, the slider slides along the inner wall of the armrest assembly, and through the connection between the connecting piece and the wire rope, the locking piece is driven to slide out of the locking groove, thereby releasing the folding restriction on the armrest assembly and the frame body. At the same time, the first elastic piece and the second elastic piece are compressed. When the pressing block is released, under the elastic force of the first elastic piece and the second elastic piece, the connecting piece drives the locking piece to slide into the locking groove, and the folding of the armrest assembly and the frame body is re-restricted. This design makes the folding and unfolding operation of the baby carriage more convenient and reliable.

[0037] Furthermore, as a preferred implementation mode of the present invention but not a limitation thereof, when the pressing block 11 is pressed downward, the sliding block 12 is pushed to slide along the inner wall of the armrest assembly 3, thereby pulling the connecting member 13 to drive the locking member 14 to slide out of the locking groove 15 to release the restriction on the armrest assembly 3 to be folded relative to the frame body 2, and release the restriction on the frame body 2 to be folded; at the same time, the first elastic member 16 and the second elastic member 17 are compressed, and the connecting member 13 drives the locking member 14 to slide into the locking groove 15 under the elastic force of the second elastic member 17 to limit the armrest assembly 3 to be folded relative to the frame body 2, and limit the frame body 2 to be folded, and the pressing block 11 is reset to the initial state under the elastic force of the first elastic member 16.

[0038] Furthermore, as a preferred embodiment of the present invention but not a limitation, it also includes a two-way lock mechanism 4 for limiting or releasing the restriction on the movement of the pressing block 11, the two-way lock mechanism 4 includes a two-way lock member 41 partially inserted into the armrest assembly 3, an abutment block 42 provided on the two-way lock member 41 and abutting against the pressing block 11, and a third elastic member 43 and a fourth elastic member 44 respectively provided at both ends of the moving direction of the two-way lock member 41 and abutting against the inside of the armrest assembly 3, the moving direction of the two-way lock member 41 is perpendicular to the moving direction of the pressing block 11.

[0039] In this embodiment, when the two locks move to either end, the contact block and the pressing block are misaligned. At this time, the pressing block and the contact block are not in contact with each other, so as to release the restriction on the movement of the pressing block. This structural setting provides an additional locking function to increase the safety of the baby stroller. When the two locks are in the locked position, the contact block and the pressing block are in contact with each other to limit the movement of the pressing block, thereby preventing the baby stroller from accidentally unfolding due to misoperation. And because the setting of the two locks may increase the complexity of the operation, the pressing block and the two locks can be respectively arranged on both sides of the armrest assembly. When the baby stroller needs to be folded, the operator can move the two locks with the thumb to release the lock, so that the pressing block can move normally, and then directly press the pressing block with the other four fingers to release the restriction on the folding of the baby stroller.

[0040] Furthermore, as a preferred implementation mode of the present invention but not limitation, a downwardly extending sinking platform 411 is provided in the middle of the second locking member 41 .

[0041] In this embodiment, in order to facilitate the operation of the two-way locking mechanism, a sunken platform is provided on the two-way locking member to facilitate the operator's finger placement, facilitate the user to perform locking and unlocking operations, and provide a force point.

[0042] Furthermore, as a preferred embodiment of the present invention but not a limitation thereof, the slider 12 is provided with a first inclined surface 121 and a second inclined surface 122 which are symmetrically arranged with each other, and the release mechanism 1 includes two sliders 12 respectively abutting against the first inclined surface 121 and the second inclined surface 122, two connecting members 13 respectively arranged on both sides of the frame body 2 and connected to the two sliders 12 by steel wire ropes, two locking members 14 sleeved on the outside of the armrest assembly 3 and respectively located on both sides of the frame body 2, and two locking grooves 15 arranged on the frame body 2 and respectively engaged with the two locking members 14.

[0043] In this embodiment, by providing a first inclined plane and a second inclined plane symmetrical to each other on the slider, the operation of the release mechanism can be made more balanced and stable. The symmetrical inclined plane design allows the two sliders to abut against the inclined plane in the same way. The slider located on the first inclined plane pulls the connecting piece close to the second inclined plane side through the steel wire rope, and the slider located on the second inclined plane pulls the connecting piece close to the first inclined plane side through the steel wire rope, which not only improves the synchronization and coordination of the mechanism, but also helps to reduce structural damage or functional failure caused by improper operation. In addition, since the two sliders are respectively located on both sides of the frame body and are connected to the corresponding connecting piece through the steel wire rope, such a layout enables the release mechanism to apply force evenly during operation, thereby improving the stability and reliability of the folding and unfolding of the baby stroller. In addition, the two locking pieces are respectively located on both sides of the frame body and are engaged with the two locking grooves. Such a design further enhances the stability and safety of the baby stroller. When folding or unfolding the baby stroller, the locking pieces on both sides can work simultaneously, ensuring the symmetry and balance of the entire structure and reducing accidents that may be caused by uneven force on one side.

[0044] Furthermore, as a preferred embodiment of the present invention but not a limitation, the frame body 2 includes a backrest bracket 21 hinged to the armrest assembly 3, a seat cushion bracket 22 hinged to the backrest bracket 21, a rear wheel group bracket 23 hinged to the backrest bracket 21, a front wheel group bracket 24 hinged to the rear wheel group bracket 23 and the seat cushion bracket 22, and a support bracket 25 whose two ends are respectively hinged to the rear wheel group bracket 23 and the armrest assembly 3.

[0045] In this embodiment, the design of the frame body forms a stable structural frame through multiple hinge points, providing the strength and durability required for a baby stroller. The hinged design of the backrest bracket, the seat bracket and the rear wheel bracket allows the main body of the baby stroller to be folded, which greatly reduces the space occupied by the baby stroller during storage and transportation and improves its portability. Moreover, during the folding process, it works in coordination with the rear wheel bracket and the seat bracket to ensure the smoothness of the folding action and the compactness of the overall structure. The two ends of the support bracket are respectively hinged to the rear wheel bracket and the armrest assembly. Such a design provides additional stability and support for the baby stroller, especially when the baby stroller is unfolded for use, which can ensure the firmness of the overall structure.

[0046] Furthermore, as a preferred implementation mode of the present invention but not a limitation, a limiting mechanism 5 for keeping the armrest assembly 3 folded relative to the frame body 2 is provided at the hinge between the support bracket 25 and the armrest assembly 3 .

[0047] In this embodiment, a limit mechanism is provided at the hinge between the support bracket and the armrest assembly for keeping the armrest assembly folded relative to the frame body. This design can effectively limit the position of the armrest assembly, so that it can remain stable after being folded and will not be randomly unfolded, thereby improving the safety of the baby stroller, so that it will only unfold when subjected to external force applied by the operator.

[0048] Furthermore, as a preferred implementation mode of the present invention but not a limitation, the limiting mechanism 5 includes a protrusion 51 provided at one end of the supporting bracket 25 and a hinge 52 provided on the armrest assembly 3, and the hinge 52 is provided with a flange 53 for the protrusion 51 to be engaged, and when the protrusion 51 is engaged with the flange 53, the armrest assembly 3 is kept folded relative to the frame body 2 without being affected by external forces.

[0049] In this embodiment, the limiting mechanism includes a protrusion provided at one end of the support bracket and a hinged member provided on the armrest assembly, and a flange for the protrusion to engage is provided on the hinged member. When the protrusion is engaged with the flange, the armrest assembly is kept folded relative to the frame body without being affected by external forces. This design can effectively limit the position of the armrest assembly, so that it can remain stable after being folded and will not be unfolded at will, thereby improving the safety and stability of the baby carriage. When the armrest assembly needs to be folded, the protrusion can be engaged with the flange, so that the armrest assembly will be fixed in the folded position and will not be unfolded under the influence of external forces. This design is simple and reliable, and can effectively prevent the armrest assembly from being accidentally unfolded, thereby avoiding possible injuries to children.

[0050] Furthermore, as a preferred implementation mode of the present scheme but not a limitation, the armrest assembly 3 is folded clockwise toward the rear wheel assembly bracket 23, driving the backrest bracket 21 to fold clockwise toward the rear wheel assembly bracket 23, and at the same time driving the seat cushion bracket 22 to fold counterclockwise toward the front wheel assembly bracket 24 and driving the support bracket 25 to fold clockwise toward the rear wheel assembly bracket 23, thereby driving the front wheel assembly bracket 24 to fold counterclockwise toward the rear wheel assembly bracket 23, and then the armrest assembly 3 is folded counterclockwise toward the support bracket 25 to complete the folding of the frame body 2.

[0051] The working principle of this embodiment is as follows:

[0052] The foldable baby stroller of the present application connects a frame body and an armrest assembly through a lock release mechanism, thereby limiting or releasing the folding of the armrest assembly relative to the frame body, and limiting or releasing the folding of the frame body at the same time, thereby simplifying the folding operation of the baby stroller, solving the problem of complicated folding operation in the prior art, and making the baby stroller more convenient when folding.

[0053] The above are implementation methods provided in combination with specific contents, and it is not intended that the specific implementation of this application is limited to these descriptions. Any method structure similar to the present application, or a number of technical deductions or replacements based on the concept of the present application, should be considered as the protection scope of this application.
