[0031] Reference Figure 1A baby stroller includes: a rotating joint 300; a handle 500, a first leg support 100, a second leg support 200, a linkage assembly 700, and a mounting structure 900. The handle 500, the first leg support 100, and the second leg support 200 are all connected to the rotating joint 300, and at least two of the three are rotatable relative to the rotating joint 300. When one of the handle 500, the first leg support 100, and the second leg support 200 rotates relative to the handle 500, at least another of the handle 500, the first leg support 100, and the second leg support 200 can be rotated via the linkage assembly 700. The mounting structure 900 is disposed outside at least two of the handle 500, the first leg support 100, and the second leg support 200, and the linkage assembly 700 is mounted outside at least two of the handle 500, the first leg support 100, and the second leg support 200 via the mounting structure 900. The 700 connecting rod assembly is externally mounted, thus avoiding damage to the internal structure of the frame tubes and maintaining the integrity and original strength of the components. This design allows the frame to better support the baby's weight and various external forces, improving the stroller's overall load-bearing capacity and stability, and extending the product's lifespan. The external mounting method avoids complex welding processes, reducing reliance on specialized welding equipment and personnel. Therefore, this stroller effectively simplifies the manufacturing process, increases production efficiency, and consequently reduces production costs, making it more competitive in the market.

[0032] In some embodiments, reference is made to Figure 2 The mounting structure 900 includes a mounting base 910, which is connected to the outer wall of the first support leg 100 or the second support leg 200. The connecting rod assembly 700 is rotatably mounted on the mounting base 910 and connected to the push handle 500. The mounting base 910 can form a mounting position on the outer wall of the first support leg 100 or the second support leg 200, thereby achieving the mounting effect of the connecting rod assembly 700 by means of drilling holes in the mounting base 910, and effectively reducing the amount of machining required on the first support leg 100 or the second support leg 200, thus ensuring that it has sufficient strength and stability.

[0033] In some embodiments, reference is made to Figure 3 The mounting base 910 is provided with multiple connecting pins 940 and is mounted to the first support leg 100 via these pins. The multiple connecting pins 940 are distributed along the length of the mounting base 910. The multiple connecting pins 940 can be used to install and fix the mounting base 910 and the first support leg 100 from different positions on the mounting base 910, thereby ensuring that the mounting base 910 is stably and reliably mounted to the first support leg 100 and preventing problems such as the mounting base 910 tilting.

[0034] Specifically, there are two connecting pins 940, which are respectively installed at both ends of the mounting base 910. Of course, there can also be three, four or other numbers of connecting pins 940. The specific implementation is not unique, but can be adjusted accordingly according to the actual situation, and no limitation is made here.

[0035] In some embodiments, reference is made to Figure 3 The mounting base 910 is provided with a connecting rivet 950, and the connecting rod assembly 700 is mounted on the connecting rivet 950. The connecting rivet 950 and the mounting base 910 are positioned between each other, and / or, the connecting rivet 950 and the connecting rod assembly 700 are rotatable relative to each other. The connecting rivet 950 not only smoothly and effectively connects the mounting base 910 and the connecting rod assembly 700, but also allows the connecting rod assembly 700 to rotate relative to the mounting base 910 via the connecting rivet 950. Furthermore, the riveting operation between the mounting base 910 and the connecting rod assembly 700 effectively avoids the first support leg 100, thereby reducing the processing of the first support leg 100 and ensuring its sufficient strength and stability.

[0036] Specifically, the linkage 700 includes a first link 710 and a second link 720, with the lower middle part of the first link 710 connected to the mounting base 910 via a connecting rivet 950.

[0037] In some embodiments, reference is made to Figure 3 A pad 920 is provided between the connecting rod assembly 700 and the mounting base 910, and a washer 930 is provided between the end of the connecting rod assembly 700 and the connecting rivet 950. The pad 920 and the washer 930 can relatively separate the mounting base 910 and the connecting rod assembly 700, and also separate the connecting rod assembly 700 and the first support leg 100 by a certain distance, thereby preventing the connecting rod assembly 700 from rubbing against the first support leg 100 during movement, and thus improving the stability of the connecting rod assembly 700, the first support leg 100 and the mounting base 910 during operation.

[0038] In some embodiments, reference is made to Figure 4 The linkage assembly 700 includes a first linkage 710 and a second linkage 720, with a mounting base 910 located on the first support leg 100. Both the push handle 500 and the mounting base 910 are rotatably connected to the first linkage 710, and both the second support leg 200 and the first linkage 710 are rotatably connected to the second linkage 720. When the push handle 500 rotates, the first linkage 710 moves along with it, causing the first support leg 100 and the second linkage 720 to move together. The second linkage 720 then moves the second support leg 200. This allows the push handle 500, the first support leg 100, and the second support leg 200 to fold or unfold synchronously, making the folding and unfolding of the stroller smoother and more convenient.

[0039] Specifically, the two ends of the first link 710 are bent relative to its middle part, so that the first link 710 can generate multi-directional forces during movement to avoid jamming.

[0040] In some embodiments, reference is made to Figure 5 and Figure 6 The push handle 500, the first support leg 100, and the second support leg 200 are all rotatably connected to the rotating joint 300. An operating handle 800 is rotatably connected to the push handle 500, and a linkage assembly 700 is rotatably connected to the operating handle 800. When the operating handle 800 rotates relative to the push handle 500, it drives the linkage assembly 700 to move relative to the push handle 500. A locking structure 600 is provided between the operating handle 800 and the push handle 500. Before and after the operating handle 800 rotates relative to the push handle 500, the positional relationship between the linkage assembly 700 and the push handle 500 will change, achieving the effect of locking and unlocking their relative movement. Therefore, by changing the positional relationship between the linkage assembly 700 and the push handle 500, the overall state of the trolley can be locked and unlocked, offering advantages such as convenient operation and simple structure.

[0041] Specifically, the push handle 500, the first support leg 100, and the first connecting rod 710 form a triangular shape. Only when the operating handle 800 is rotated to be flush with the push handle 500 does the push handle 500 and the first support leg 100 approach a right angle, thus stabilizing the overall torque and achieving a supporting effect in the unfolded state. Locking the operating handle 800 at this point locks the position of the first connecting rod 710, thereby fixing the trolley in its fixed state.

[0042] In some embodiments, reference is made to Figure 7The locking structure 600 includes a first mounting member 610 and a second mounting member 620. The first mounting member 610 is connected to the operating handle 800, and the second mounting member 620 is connected to the push handle 500. The first mounting member 610 and the second mounting member 620 are rotatably connected. One of the first mounting member 610 and the second mounting member 620 is equipped with a snap-fit ​​member 650. The other of the first mounting member 610 and the second mounting member 620 is provided with a snap-fit ​​portion 615, and the snap-fit ​​member 650 can snap and fix itself to the snap-fit ​​portion 615. A pusher 630 is provided between the first mounting member 610 and the second mounting member 620, and the pusher 630 can push the snap-fit ​​member 650 away from the snap-fit ​​portion 615. When locking is required, the state of the pusher 630 can be adjusted to prevent pushing the snap-fit ​​member 650. In this state, the latching member 650 can latch into the latching part 615, thereby achieving the latching and fixing effect of the first mounting member 610 and the second mounting member 620, and thus achieving the purpose of locking the operating handle 800 and the push handle 500. When unlocking is required, the latching member 650 can be pushed by the pushing member 630, thereby moving the latching member 650 away from the latching part 615 and canceling the latching effect between them, so that the first mounting member 610 and the second mounting member 620 can rotate relative to each other, and achieve the purpose of unlocking.

[0043] Specifically, the locking part 615 is disposed on the first mounting member 610, and the second mounting member 620 and the locking member 650 are locked together so that the locking member 650 can slide only relative to the second mounting member 620. A push spring 640 is disposed between the first mounting member 610 and the second mounting member 620, which can push the locking member 650 toward the locking part 615, thereby locking it in a timely manner.

[0044] In some embodiments, reference is made to Figure 7The pusher 630 is rotatably mounted on the first mounting member 610, and the pusher 630 and the first mounting member 610 are in contact via an arc-shaped inclined surface. The pusher 630 is connected to a pull rope 680, and the operating handle 800 or push handle 500 is equipped with an unlocking button 690. The pull rope 680 is connected to the unlocking button 690. The unlocking button 690 can smoothly and effectively drive the pull rope 680 to move, thereby driving the pusher 630 to rotate. When the pusher 630 rotates, its position relative to the first mounting member 610 will change due to the inclination effect of the arc-shaped inclined surface. This positional change pushes the locking member 650, thus achieving the effect of pushing the locking member 650 away from the locking part 615. When the pull rope 680 pulls the pusher 630 in the opposite direction, the pusher 630 moves closer to the first mounting member 610. At this time, the locking part 650 will automatically engage with the locking part 615 under the action of the push spring 640, thereby achieving a quick locking effect.

[0045] In some embodiments, reference is made to Figure 8 The operating handle 800 is connected to a grip 400, and an unlock button 690 is movably mounted on the grip 400. The grip 400 is equipped with a ramp slider 450. When the unlock button 690 moves relative to the grip 400, it pushes against the ramp slider 450. A pull cord 680 is connected to the ramp slider 450. The grip 400 is equipped with a return spring 670 for pushing the unlock button 690. When the unlock button 690 is pressed, it will drive the ramp slider 450 to move, thereby driving the pull cord 680 connected to the ramp slider 450 to move, thus achieving the operating effect of the locking part 615. The return spring 670 allows the unlock button 690 to automatically spring back after the force of pressing it is released, thus quickly restoring the locked or unlocked state.

[0046] Specifically, the grip 400 is equipped with a return spring 430, which is connected to the inclined slider 450 and can automatically and promptly return to its original position after the unlock button 690 is reset.

[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
