[0027] Example 1: like Figure 1-6 As shown, the present invention proposes a detachable structure for a stroller canopy, including a stroller body 3, a stroller frame 4, and wheels 5. The stroller body 3 has an upward opening and is fixed inside the stroller frame 4. The four wheels 5 are all installed at the bottom of the stroller frame 4. It also includes a canopy 2, which is detachably connected to the upper side of the stroller body 3. A second mounting strip 16 is fixed to the bottom edge of the car roof 2, and a first magnetic alignment component is provided at the bottom of the second mounting strip 16; a first mounting strip 7 adapted to the second mounting strip 16 is installed on the upper edge of the stroller body 3, and a second magnetic alignment component matching the first magnetic alignment component is mounted on the first mounting strip 7. The outer end face of the stroller body 3 is fixed with a mounting shell 6, and the mounting shell 6 is provided with a drive limiting mechanism. The upper end of the mounting shell 6 is symmetrically provided with a through first insertion hole 602 on both sides. The outer ends of the second mounting strip 16 are fixed with plugs 8 that can be inserted into the first insertion hole 602. The middle of the plugs 8 is provided with a through second insertion hole 801, and the plugs 8 can cooperate with the drive limiting mechanism.

[0028] In this invention, the car roof 2 is first positioned quickly and initially by means of a magnetic alignment component, and then a stable locking is achieved by means of a drive limiting mechanism and a plug 8, which ensures the stability of the car roof 2 after installation. At the same time, the layout of each component is adapted to the structure of the stroller body 3 and the stroller frame 4. It should be noted that the first magnetic alignment component and the second magnetic alignment component ensure that the magnetic attraction force of the two is uniform and sufficient to support the positioning of the roof 2, while the magnetic attraction force needs to be controlled within a reasonable range; the adaptation of the second mounting strip 16 and the first mounting strip 7 not only refers to the size fit, but also ensures that after the contact surfaces of the two are aligned, the plug 8 can be aligned with the first plug hole 602 of the mounting housing 6.

[0029] When using the stroller, a removable baby safety pad and a five-point safety harness must first be placed inside the stroller body 3.

[0030] In an optional embodiment, the drive limiting mechanism consists of a plug rod 15, a connecting rod 13, a moving block 12, and a drive assembly; the mounting housing 6 has a U-shaped structure, the moving block 12 is located in the middle of the inner cavity of the mounting housing 6, and the two ends of the moving block 12 are connected to the plug rod 15 respectively through the connecting rod 13, and the plug rod 15 can be inserted into the corresponding second insertion hole 801.

[0031] It should be noted that when the insert rod 15 is inserted into the second insertion hole 801, it can mechanically limit the insertion block 8, thereby fixing the car canopy 2 to the stroller body 3.

[0032] In an optional embodiment, the drive assembly includes a threaded rod 14 and a rotating handle 10; one end of the threaded rod 14 is vertically rotatably connected to the outer wall of the stroller body 3 and located inside the mounting housing 6, and the other end passes through the outer wall of the mounting housing 6 and is coaxially fixed to the rotating handle 10; the middle part of the threaded rod 14 passes through the moving block 12 through the thread, and the outer wall of the threaded rod 14 adopts a triangular thread design.

[0033] It should be noted that the user only needs to turn the rotary handle 10 to drive the threaded rod 14 to rotate. Since the threaded rod 14 and the moving block 12 are connected by a thread, the rotation of the threaded rod 14 will be converted into the linear movement of the moving block 12 along the axial direction of the threaded rod 14, thereby driving the insertion rod 15 to complete the insertion or extraction action.

[0034] The triangular thread design has good self-locking properties, which can effectively prevent the moving block 12 from sliding on its own when not in operation.

[0035] In an optional embodiment, the device further includes a mounting block 9 and a sliding rod 11; the mounting block 9 is slidably sleeved on the outer wall of the connecting rod 13 and fixedly connected to the inner wall of the mounting housing 6; a plurality of sliding rods 11 slide through the moving block 12, the moving block 12 being located between the outer wall of the stroller body 3 and the inner wall of the mounting housing 6, and the sliding rods 11 and the threaded rod 14 remain parallel.

[0036] It should be noted that the mounting block 9 serves as a guide for the connecting rod 13, restricting the connecting rod 13 to move only in the horizontal direction, preventing the connecting rod 13 from shifting during movement, and ensuring that the insertion rod can be aligned and inserted into the second insertion hole.

[0037] In an optional embodiment, a mounting slot 601 is also included; the mounting slot 601 is formed on the inner wall of the mounting housing 6, and the insertion rod 15 can pass through the second insertion hole 801 and be inserted into the mounting slot 601.

[0038] It should be noted that when the insertion rod 15 passes through the second insertion hole 801 and is further inserted into the mounting slot 601, both ends of the insertion rod 15 are supported by the inner wall of the mounting housing 6 and the outer wall of the stroller body 3, respectively, which improves the limiting strength of the insertion rod 15 and enhances the installation stability of the stroller canopy 2.

[0039] In an optional embodiment, the outer wall of the stroller body 3 is made of a rigid material.

[0040] It should be noted that the rigid material can be 6061-T6 aluminum alloy, food-grade ABS plastic, or modified PP plastic, with 6061-T6 aluminum alloy being the preferred choice.

[0041] In an optional embodiment, the grip portion of the stroller frame 4 is fitted with a grip sleeve 1.

[0042] It should be noted that the grip sleeve 1 improves the comfort of holding the handle of the stroller frame 4.

[0043] In an optional embodiment, the four wheels 5 include two self-locking directional wheels and two omnidirectional wheels; the two directional wheels are mounted on the bottom of the stroller body 3 on the side away from the front of the stroller, and the two omnidirectional wheels are mounted on the bottom of the stroller body 3 on the side closer to the front of the stroller.

[0044] It should be noted that the self-locking wheels can lock the stroller in place when it stops, preventing the stroller from sliding and avoiding safety risks to the baby due to accidental sliding.

[0045] Example 2: like Figure 3 , 4 As shown in Figures 5 and 7, based on Embodiment 1, the bottom inner cavity of the second mounting strip 16 is provided with a plurality of second magnetic strips 1602 at intervals, and the second mounting strip 16 is provided with a plurality of through-holes 1601. The upper end of the first mounting strip 7 is embedded with a plurality of first magnetic strips 701 that cooperate with the second magnetic strips 1602 to magnetically attract each other, and the upper end of the first mounting strip 7 is fixed with a plurality of aligning rods 702 that can be inserted into the aligning holes 1601.

[0046] It should be noted that the multiple second magnetic strips 1602 are connected to the multiple first magnetic strips 701 by magnetic attraction, which can enhance the magnetic attraction between the second mounting strip 16 and the first mounting strip 7, play a role in initial positioning, and also avoid the unstable positioning of the roof liner 2 due to insufficient magnetic force of a single magnetic strip; the alignment hole 1601 cooperates with the alignment rod 702 on the first mounting strip 7 to achieve physical alignment before magnetic positioning, and guide the second mounting strip 16 to fit against the first mounting strip 7.

[0047] Working principle: When the car roof 2 needs to be installed, first align the second mounting strip 16 at the bottom of the car roof 2 with the first mounting strip 7 at the top of the stroller body 3, so that the alignment hole 1601 on the second mounting strip 16 is aligned with the alignment rod 702 on the first mounting strip 7. Insert the alignment rod 702 to achieve the initial alignment of the car roof 2 and the stroller body 3. Furthermore, the second magnetic strip 1602 inside the second mounting strip 16 and the first magnetic strip 701 embedded in the first mounting strip 7 attract each other due to magnetic force, so that the second mounting strip 16 and the first mounting strip 7 fit together, thus completing the positioning of the car roof 2.

[0048] At this time, the insert 8 on the outer side of the second mounting strip 16 is inserted into the first insertion hole 602 at the upper end of the mounting housing 6. At this time, the second insertion hole 801 on the insert 8 is aligned with the position of the insert rod 15 inside the mounting housing 6. Then, the user rotates the rotating handle 10, and the threaded rod 14, which is coaxially fixed with the rotating handle 10, rotates accordingly. It is connected to the moving block 12 through a threaded engagement, and the rotation of the threaded rod 14 is converted into the linear movement of the moving block 12 along the axial direction of the threaded rod 14.

[0049] When the movable block 12 moves, the connecting rods 13 at both ends drive the insertion rod 15 to move. After the insertion rod 15 passes through the second insertion hole 801 on the insertion block 8, it is inserted into the mounting groove 601 on the inner wall of the mounting housing 6, thus completing the mechanical limit locking of the roof 2.

[0050] When the car roof 2 needs to be removed, the user rotates the handle 10 in the opposite direction, causing the threaded rod 14 to rotate in the opposite direction. The moving block 12 moves along the axial direction of the threaded rod 14 away from the stroller body 3. The moving block 12 drives the insertion rod 15 to move in the opposite direction through the connecting rod 13. The insertion rod 15 gradually moves out of the mounting groove 601 and the second insertion hole 801 until it is completely removed from the second insertion hole 801, thereby releasing the limitation on the insertion block 8.

[0051] At this time, the user can lift the roof 2 upwards, and the second magnetic strip 1602 in the second mounting strip 16 will separate from the first magnetic strip 701 in the first mounting strip 7. The alignment rod 702 will be pulled out from the alignment hole 1601, and the roof 2 can be disassembled.

[0052] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
