[0039] First embodiment, reference Figures 1-7 .

[0040] This embodiment provides a baby stroller, including a stroller body 1 and a bassinet 2. The stroller body 1 includes a base frame 11, a movable frame 12, and a lifting assembly 13. The movable frame 12 includes a pull handle 1211 and a space for placing the bassinet 2, which is detachably placed inside the movable frame 12. The base frame 11 includes a first support rod 111, a second support rod 112, and a third support rod 113 that is horizontally arranged and connects the first support rod 111 and the second support rod 112. The bottom of the movable frame 12 is provided with a first connecting seat 123 and a second connecting seat 124 corresponding to the positions of the first support rod 111 and the second support rod 112. The first connecting seat 123 is connected by... The pivot is rotatably connected to the first support rod 111, and the second connecting seat 124 is movably engaged with the second support rod 112; the lifting assembly 13 is disposed on the third support rod 113, and the driving end of the lifting assembly 13 is connected to the bottom of the movable frame 12. The lifting assembly 13 is used to lift the movable frame 12 upward or downward; during the lifting or lowering of the movable frame 12, the first connecting seat 123 rotates relative to the first support rod 111 around the pivot, and the second connecting seat 124 separates from the second support rod 112; when the movable frame 12 is lowered to the horizontal position of the sleeping basket 2, the second connecting seat 124 is connected to the second support rod 112. The base frame 11, movable frame 12, and lifting assembly 13 of the stroller body 1 work together. The first support rod 111 and the second support rod 112 of the base frame 11 provide stable support. The movable frame 12 is used to place the bassinet 2 and realize angle adjustment. The lifting assembly 13 drives the movable frame 12 to be raised or lowered. The first connecting seat 123 and the second connecting seat 124 cooperate with the first support rod 111 and the second support rod 112 respectively to realize the rotation function of the movable frame 12. By setting the lifting assembly 13, the problem of fixed angle and inability to adjust the bassinet 2 of traditional baby strollers is solved. It can realize flexible angle adjustment function, which makes it convenient for parents to adjust the stroller according to different usage scenarios (such as the baby lying flat when sleeping, adjusting the height or angle when going out to take care of the baby, etc.), thus improving the convenience and comfort of use.

[0041] A locking element 16 is provided at the upper end of the second support rod 112. When the second connecting seat 124 is connected to the second support rod 112, the locking element 16 is used to lock the second connecting seat 124 and the second support rod 112 in a movable engagement to limit the lifting of the movable frame 12. When the locking element 16 releases the lock on the movable engagement between the second connecting seat 124 and the second support rod 112, the movable frame 12 can be raised or lowered. When the movable frame 12 is lowered to a horizontal position on the bassinet 2, the locking element 16 is used to limit the lifting of the movable frame 12 to ensure the stability and safety of the stroller during use. When parents need to adjust the angle of the bassinet 2, they can release the lock on the second connecting seat 124 through the locking piece 16, so that the second connecting seat 124 can be detached from the second support rod 112. At this time, the lifting component 13 can be operated to adjust the angle of the bassinet 2. When no adjustment is needed, the movable frame 12 is lowered to place the bassinet 2 horizontally, and the second connecting seat 124 is connected and locked to the second support rod 112 by the locking piece 16. This can prevent children from accidentally operating the lifting component 13 and causing the crib to tilt, thus playing a safety protection role.

[0042] The base frame 11 is equipped with movable wheels 14 at the bottom, making it easy for parents to move the stroller when going out. The movable wheels 14 are omnidirectional wheels, and the omnidirectional wheels are equipped with locking mechanisms 141, which can be used to lock the omnidirectional wheels. The movable frame 12 includes a pull handle 1211, which makes it easy for parents to operate the stroller, improving the practicality and flexibility of the stroller.

[0043] like Figure 4 Specifically, the lifting assembly 13 includes a first pressure plate 131, a first traction rope 132, a first return spring, and a first lifting gas spring 133. One end of the first traction rope 132 is connected to the first lifting gas spring 133, and the other end is connected to the first pressure plate 131. The first lifting gas spring 133 is mounted on the third support rod 113, and the driving end of the first lifting gas spring 133 is connected to the bottom of the movable frame 12, providing lifting power for the movable frame 12. A first mounting shell 125 is provided on the bottom surface of the pull part 1211, and the first pressure plate 131 is mounted on the first mounting shell 125. The first return spring is installed inside the first mounting shell 125 and is connected to the first pressure plate 131. The first return spring (not shown in the figure) plays a reset role, so that the lifting assembly 13 can automatically return to its initial state after use, ensuring the normal operation of the lifting assembly 13.

[0044] It should be noted that the structure and cooperation of the return spring, traction rope, and lifting gas spring are existing technologies and will not be elaborated on here. Through the cooperation of the first pressure plate 131, the first traction rope 132, the first return spring, and the first lifting gas spring 133, the movable frame 12 can be smoothly raised and lowered, which is simple and convenient to operate and improves the performance and user experience of the trolley.

[0045] When the first pressure plate 131 is pressed, the first return spring is compressed, and the first traction rope 132 pulls the drive end of the first lifting gas spring 133, activating the first lifting gas spring 133. The drive end of the first lifting gas spring 133 pushes the movable frame 12 upward, causing the first connecting seat 123 to rotate relative to the first support rod 111 around the pivot. The second connecting seat 124 separates from the second support rod 112, and the first lifting gas spring 133 lifts the movable frame 12 upward. After the first pressure plate 131 is released, the first return spring returns to its original deformation, pushing the first pressure plate 131 back to its original position. At the same time, the drive end of the first lifting gas spring 133 is released, closing the first lifting gas spring 133. At this time, the movable frame 12 remains in the tilted state after being lifted. When the lower movable frame 12 is needed, press down the first pressure plate 131 again and maintain the pressure. This activates the first lifting gas spring 133. Pressing down the movable frame 12 will cause the first lifting gas spring 133 to move downwards, pressing it down until the movable frame 12 is lowered to a horizontal position in the bassinet 2. Then release the first pressure plate 131. Positioning the first pressure plate 131 below the handle 1211 allows for easy pulling and pushing of the stroller, while also enabling manual operation to raise the first pressure plate 131. This reasonable positioning of the first pressure plate 131 facilitates manual control of the raising operation.

[0046] The bottom of the movable frame 12 is provided with a first hinge seat 126, and the third support rod 113 is provided with a second hinge seat 114. The driving end of the first lifting gas spring 133 is hinged to the first hinge seat 126, and the main body of the first lifting gas spring 133 is hinged to the second hinge seat 114. The arrangement of the first hinge seat 126 and the second hinge seat 114 ensures that the first lifting gas spring 133 can stably connect the movable frame 12 and the third support rod 113, ensuring that the movable frame 12 can rotate flexibly around the hinge point during lifting and lowering, while maintaining a stable connection with the base frame 11, thus preventing the movable frame 12 from shaking or being damaged due to improper connection methods.

[0047] like Figure 2The movable frame 12 includes an annular frame 121 and U-shaped support rods 122 connected to the annular frame 121 at both ends. The annular frame 121 and the U-shaped support rods 122 together form a space for placing the sleeping basket 2, and the sleeping basket 2 can be detachably placed in the space. The handle 1211 is installed on one side of the annular frame 121. The first connecting seat 123 and the second connecting seat 124 are provided at the bottom of the U-shaped support rods 122, and the driving end of the lifting component 13 is connected to the bottom of the U-shaped support rods 122.

[0048] The annular frame 121 includes an annular placement opening 1212. The bassinet 2 has an annular locking part 21 along its upper edge in the height direction, and the annular locking part 21 protrudes outward. The annular locking part 21 is engaged with the annular placement opening 1212. The U-shaped support rod 122 provides support for the bassinet 2, so that the bassinet 2 is fixed in the movable frame 12, ensuring that the bassinet 2 is stably fixed in the movable frame 12 and will not loosen or shift. This ensures that the bassinet 2 will not loosen during use, providing a stable sleeping environment for the baby. The bassinet 2 is detachably placed in the movable frame 12 by engaging the annular locking part 21 with the annular placement opening 1212. The bassinet 2 can be disassembled and installed as needed, making it convenient for parents to change or clean the bassinet 2 as needed. The cooperation between the annular locking part 21 and the annular placement opening 1212 achieves a stable connection between the bassinet 2 and the movable frame 12. Even during stroller movement or angle adjustment, the bassinet 2 will not easily loosen or fall off, ensuring the baby's safety and comfort.

[0049] like Figure 4 , Figure 6 The second connecting seat 124 is provided with a snap-fit ​​part 1241, and the end of the second support rod 112 is provided with a slot 1121. When the second connecting seat 124 is connected to the second support rod 112, the snap-fit ​​part 1241 is inserted into the slot 1121, thereby realizing the connection between the movable frame 12 and the base frame 11. Figure 7 The locking member 16 includes a lock seat 161 fixed on the second support rod 112, a pressing member 162 hinged to the lock seat 161, and a fastener 163 connected to the pressing member 162. The second connecting seat 124 is provided with a locking groove 1242. The fastener 163 includes a hook portion 1631, which cooperates with the locking groove 1242 to achieve locking. The pressing member 162 is used to lock the hook portion 1631 in the locking groove 1242 or to release the lock portion 1631 from the locking groove 1242.

[0050] The operation of the locking member 16 is as follows: when the movable frame 12 is lowered to the horizontal position of the sleeping basket 2, the second connecting seat 124 is connected to the second support rod 112. After the snap-fit ​​part 1241 is inserted into the snap-fit ​​groove 1121, the hook part 1631 of the fastener 163 is hooked into the locking groove 1242. The pressing member 162 is pressed towards the second support rod 112, and the fastener 163 is tightened by pressing the pressing member 162. After the fastener 163 is tightened, the hook part 1631 is locked in the locking groove 1242 to achieve locking. To unlock, simply pry the pressing member 162 away from the second support rod 112 to release the tension on the fastener 163. After the fastener 163 is released, the hook part can be disengaged from the locking groove 1242 to unlock.

[0051] like Figure 2 , Figure 5 A storage box 3 is detachably mounted on one side of the movable frame 12, located below the pull handle 1211. The storage box 3 provides parents with extra storage space for baby items such as diapers and toys. Its detachable design allows the storage box 3 to be installed or removed as needed, making it more flexible to use.

[0052] like Figure 1 , Figure 3 The base frame 11 includes a bottom tray 15. The bottom tray 15 can be used to place baby's shoes, backpacks, and other items, increasing the stroller's storage function and also helping to keep the stroller tidy. The four corners of the bottom tray 15 are equipped with anti-collision silicone 151, which effectively prevents damage to the base frame 11 when the stroller collides with other objects during movement or parking. It also reduces noise from collisions, protects the baby's sleeping environment, and improves the stroller's durability and comfort.

[0053] The baby stroller provided in this embodiment achieves convenient raising and lowering of the movable frame 12 through the design of the lifting component 13 and the detachable bassinet 2, while ensuring the stable fixation of the bassinet 2. Furthermore, the lifting component and the storage box 3 further enhance the stroller's functionality and practicality. This stroller has a simple structure, is easy to operate, and can meet the needs of parents in different scenarios.

[0054] Second embodiment, such as Figure 8 .

[0055] Based on the first embodiment, a lifting assembly (not shown in the figure) is installed on the base frame 11. Both the first support rod 111 and the second support rod 112 are telescopic rods. The lifting assembly simultaneously drives the first support rod 111 and the second support rod 112 to extend and retract, and through the extension and retraction of the first support rod 111 and the second support rod 112, it drives the movable frame 12 to rise or fall, realizing the height adjustment function of the movable frame 12 to meet the height requirements of the stroller in different scenarios. This enriches the functionality of the baby stroller, providing multiple functions such as angle adjustment, height adjustment, and item storage, meeting the usage needs of parents in different scenarios.

[0056] Specifically, the telescopic rod includes a fixed rod and a movable rod; the lifting assembly includes a second pressure plate 128, a second traction rope, a second return spring, and a second lifting gas spring; one end of the second traction rope is connected to the second lifting gas spring, and the other end is connected to the second pressure plate; a connecting seat is installed on the driving end of the second lifting gas spring, and the connecting seat is connected to the movable rod; a second mounting shell 127 is provided on the bottom surface of the pull part 1211 (e.g., ...). Figure 8 The second pressure plate 128 is installed in the second mounting shell 127; the second return spring is installed in the second mounting shell 127 and is connected to the second pressure plate 128.

[0057] When the second pressure plate 128 is pressed, the second return spring is compressed, and the second traction rope pulls the drive end of the second lifting gas spring, activating the second lifting gas spring. This, through the connecting seat, causes the movable rod to rise. After the second pressure plate 128 is released, the second return spring returns to its original shape, pushing the second pressure plate back to its original position. Simultaneously, the drive end of the second lifting gas spring is released, closing the second lifting gas spring and completing the height adjustment. When it is necessary to lower the height, press down on the second pressure plate 128 and maintain the pressure; the movable frame will then lower.

[0058] The structure that simultaneously drives the first support rod and the second support rod to extend and retract is as follows: a second lifting gas spring is provided inside the first support rod 111 and the second support rod 112. The two second lifting gas springs are connected to the same second pressure plate 128 through two second traction ropes. The first support rod 111 and the second support rod 112 are simultaneously operated to extend and retract through the second pressure plate 128.

[0059] The above description is only a preferred embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model by those skilled in the art within the scope of the technology disclosed in the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
