Description
[Technical Field]
[0001] This utility model relates to a children's stroller with a luggage compartment. [Background Technology]
[0002] Strollers have become a common tool for parents when traveling with children, but existing strollers are relatively simple in function, usually only providing a place for children to sit. When parents travel with children, they often also need to carry suitcases or other personal items, which requires operating both the stroller and the suitcase simultaneously. This not only increases the burden of carrying things but also easily causes inconvenience, especially in scenarios that require frequent movement or changes of transportation. Existing strollers fail to meet users' needs for convenience and multifunctionality.
[0003] Currently, there are already children's stroller products on the market with luggage compartments. The luggage compartments are detachably connected to the stroller frame, and the two are connected and locked by a locking mechanism. However, the traditional locking mechanism between the luggage compartment and the stroller frame is relatively complicated, and the unlocking operation is inconvenient, making it difficult to assemble and disassemble the luggage compartment.
[0004] Therefore, this utility model was created based on the above-mentioned shortcomings. [Utility Model Content]

The first return spring 45 is compressed. Once the locking hook 44 and the locking groove 41 are fully aligned, the first return spring 45 extends and returns to its original position, pushing the locking hook 44 into the locking groove 41, at which point the suitcase 2 is securely installed onto the main support member 1. Therefore, when installing the suitcase 2, simply engage the engaging part 46 and the locking position 47, and then push the suitcase 2; the operation is very convenient and quick. When it is necessary to disassemble the suitcase 2, simply push the handle 43 upwards to disengage the locking hook 44 from the locking groove 41, and then pull the suitcase 2 outwards to remove it; the operation is also very convenient and quick. Furthermore, the handle 43 is located under the seat 12 to prevent children from accidentally touching it, avoiding accidental locking and ensuring safety. In this embodiment, the engaging part 46 is two protrusions on the suitcase 2, and the locking position 47 is two grooves on the main crossbar 13.
[0035] like Figure 1 and Figure 2As shown, the upper end of the suitcase 2 is provided with a first insertion groove 22 into which the seat plate 122 can be inserted.

The side of the luggage compartment 2 is also provided with a second insertion slot 24 that communicates with the snap-fit slot 23 and allows the secondary support member 3 to be inserted when folded relative to the main support member 1, so that the stroller occupies less space when folded and is easy to store.
[0037] like Figure 8 and Figure 9 As shown, the secondary support rod 31 is rotatably connected to the fixed base 121 via the connecting seat 34 at its upper end. The second locking mechanism 5 includes a button 51 that is slidably disposed in the fixed base 121 and exposed. The button 51 is provided with a transverse locking pin 52. The fixed base 121 is provided with a straight groove 53 for the locking pin 52 to slide inside. The connecting seat 34 is provided with a first engaging groove 54 that extends radially and can engage with the locking pin 52 to lock the secondary support member 3 in the unfolded position. The connecting seat 34 is provided with an arc-shaped groove 55 that communicates with the first engaging groove 54 and allows the locking pin 52 to move relative to it after it is withdrawn from the first engaging groove 54. The connecting seat 34 is also provided with a second engaging groove 56 that communicates radially with the arc-shaped groove 55 and can engage with the locking pin 52 to lock the secondary support member 3 in the folded position. A second return spring 57 that can push the button 51 to reset is also provided between the fixed base 121 and the button 51. When the secondary support 3 needs to be folded, press button 51 to allow locking pin 52 to slide within the straight groove 53. Locking pin 53 then exits from the first engaging groove 54 on the connecting seat 34 and enters the arc-shaped groove 55. At this point, the secondary support 3 can be rotated relative to the main support 1. When the secondary support 3 moves closer to the main support 1, locking pin 52 aligns with the second engaging groove 56. Release button 51, and the second return spring 57 extends and returns to its original position. Locking pin 52 then enters the second engaging groove 56, locking the folded state of the secondary support 3 and the main support 1 together, preventing accidental unfolding and facilitating the storage of the stroller. When the secondary support 3 needs to be unfolded again, simply press button 51 again and rotate the secondary support 3 outwards. When the secondary support 3 is fully unfolded, locking pin 52 engages again within the first engaging groove 54, locking the unfolded state of the stroller.
[0038] like Figure 1 and Figure 2 As shown, the secondary support rod 31 is also equipped with a foot pedal 35 that can be rotated and unfolded or folded relative to it. When the secondary support rod 31 is folded relative to the main support rod 1, the foot pedal 35 is folded relative to the secondary support rod 31 and placed into the second insertion slot 24. When the stroller is folded, the foot pedal 35 can be rotated and folded relative to the secondary support rod 31 and stored in the second insertion slot 24 on the luggage compartment 2, thereby reducing the space occupied by the stroller and making it easier to store.
[0039] like Figures 7 to 11As shown, the main support rod 11 has a sliding support rod 16 inside it, and a horizontal armrest 17 on the support rod 16, which children can hold when sitting in the seat to ensure safety. A third locking mechanism 6 is provided between the support rod 16 and the main support rod 11 to lock the two together. The support rod 16 also has a sliding push rod 18 inside it, and a push handle 19 is provided at the upper end of the push rod 18. A fourth locking mechanism 7 is provided between the push rod 18 and the support rod 16. The push rod 18 has an unlocking part 10 that can drive the fourth locking mechanism 7 to unlock. The lower end of the push rod 18 has a pushing part 181 that can drive the third locking mechanism 6 to unlock when it slides inward relative to the support rod 16. When using the stroller, the user pushes it using the handle 19. When folding the stroller, the user first unlocks the fourth locking mechanism 7 and then retracts the push rod 18 into the support rod 16. During the retraction process, the push part 181 at the lower end of the push rod 18 pushes the third locking mechanism 6, causing the third locking mechanism 6 to unlock. The support rod 16 then retracts into the main support rod 11, thereby realizing the folding of the support rod 16 and the push rod 18. Moreover, unlocking the fourth locking mechanism 7 and pushing the push rod 18 can achieve the linkage unlocking of the third locking mechanism 6, making the stroller folding convenient and quick. Specifically, the fourth locking mechanism 7 includes multiple locking holes 71 on the support rod 16. The push rod 18 has a locking block 72 that can move laterally and engage or disengage from the locking holes 71. The push rod 18 has a sliding block 73 that can slide along it. The sliding block 73 has a first V-shaped groove 74 that opens to one side. The locking block 72 has a first mating block 75 that engages with the first V-shaped groove 74 and can be pushed by the groove wall of the first V-shaped groove 74 when the sliding block 73 slides. A fourth return spring 76 that can push the sliding block 73 to slide back to its original position is also provided between the push rod 18 and the sliding block 73. A sixth return spring 77 that can push the locking block 72 to reset is provided between the locking block 72 and the push rod 18. The unlocking component 10 includes an unlocking block 101 exposed on the push handle 19. The unlocking block 101 has a push rod 102. The lower end of the push rod 102 has a push block 103 that can push the sliding block 73 to slide. When the user presses the unlocking block 101, the push rod 102 moves downward and pushes the sliding block 73 through the push block 103. The groove wall of the first V-shaped groove 74 on the sliding block 73 pushes the first mating block 75 on the locking block 72, thereby converting the longitudinal movement of the sliding block 73 into the lateral movement of the locking block 72, so that the locking block 72 disengages from the locking hole 71 on the support rod 16, thus unlocking the fourth locking mechanism 7. In this embodiment, the support rod 16 is provided with multiple locking holes 71, and the user can adjust the extension length of the push rod 18 to comfortably push the stroller.
[0040] like Figure 8 and Figure 11As shown, the third locking mechanism 6 includes a locking hole 61 on the main support rod 11, a fixing block 62 inside the support rod 16, a locking block 63 slidably disposed inside the fixing block 62 that can engage or disengage with the locking hole 61, a sliding seat 64 slidably disposed inside the support rod 16 that can slide relative to the fixing block 62, a second V-shaped groove 65 opening to one side on the sliding seat 64, a second mating block 66 on the locking block 63 that engages with the second V-shaped groove 65 and can be pushed by the groove wall of the second V-shaped groove 65 when the sliding seat 64 slides, a third return spring 67 that can push the sliding seat 64 to slide back to its original position between the fixing block 62 and the sliding seat 64, and a fifth return spring 68 that can push the locking block 63 to reset between the locking block 63 and the fixing block 62. When the push rod 18 retracts into the support rod 16, the pushing part 181 at the lower end of the push rod 18 pushes the sliding seat 64, and the groove wall of the second V-shaped groove 65 on the sliding seat 64 pushes the second mating block 66 on the locking block 63, so that the locking block 63 moves laterally and disengages from the locking hole 61 on the main support rod 11, thereby unlocking the third locking mechanism 6.
