[0057] Those skilled in the art should understand that in the disclosure of this application, the orientation or positional relationships indicated by the terms "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings. These are only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting this application.

[0058] The following further elaborates on this application in conjunction with the drawings. Refer to, for example, Figures 1 to 10 the description.

[0059] This application provides a baby strolling suitcase (hereinafter referred to as the suitcase). As shown in, for example, Figures 1 to 3 Figure, the suitcase 1 includes a box body 2 and a frame 3. The frame 3 is detachably connected to the box body 2, enabling the separate use function of the box body 2. Thus, when placing and taking items in the box body 2, the box body 2 can be detached for use, avoiding operating on the entire suitcase 1, reducing clumsiness, and facilitating the operation of the box body 2, thereby improving the user experience. Further, as shown in, for example, Figure 5 Figure, the frame 3 includes a seat cushion 5. The seat cushion 5 is located at the upper end of the box body 2. The box body 2 is provided with a limiting structure that can limit and fix the seat cushion 5 relative to the box body 2, thereby ensuring the stability of the connection between the seat cushion 5 and the box body 2. When a child sits on the seat cushion 5 of the suitcase 1, the stability of the child sitting on the suitcase 1 can be ensured, improving safety. Moreover, for the convenience of detaching the seat cushion 5 from the box body 2, the suitcase 1 is also provided with an unlocking mechanism 7. The unlocking mechanism 7 is connected to the seat cushion 5. Through the unlocking mechanism 7, the user can conveniently unlock the box body 2 and the seat cushion 5, enabling the seat cushion 5 to be detached from the box body 2 for the convenience of using the box body 2 alone.

[0060] Specifically, as shown in, for example, Figures 3 to 5 Figure, the frame 3 further includes a connecting seat 4 and a connecting rod 6. The connecting rod 6 is connected to the upper end of the connecting seat 4. The lower end of the connecting seat 4 is provided with rotating wheels for assisting in pushing the suitcase 1 to rotate. The main body of the connecting seat 4 is in a "field" shape. The box body 2 is provided with a mounting groove 31. As shown in, for example, Figure 4As shown in the figure, the installation groove 31 is divided into a part provided on the back of the box body 2 and a part provided at the upper end. The structure of the installation groove 31 on the back of the box body 2 corresponds to the structure of the connecting seat 4 for installing the connecting seat 4; the cushion 5 is connected to the front end of the connecting seat 4, and the installation groove 31 at the upper end part of the box body 2 is used for installing the cushion 5; wherein, a limiting structure is provided at the upper end of the box body 2, and an installation structure is provided on the lower end surface of the cushion 5. The limiting structure cooperates with the installation structure so that the cushion 5 can be stably connected to the box body 2, ensuring that when a child sits on the cushion 5, the cushion 5 can remain stable relative to the box body 2 and is not easily shaken, thus guaranteeing the safety of the child's ride.

[0061] In this embodiment, the cushion 5 is rotatably connected to the connecting seat 4, and the luggage case 1 is provided with an unlocking mechanism 7. The unlocking mechanism 7 is connected to the cushion 5 and is used to unlock the lock between the cushion 5 and the box body 2 by operating the unlocking mechanism 7. The user can operate the luggage case 1 independently, which is more convenient for the user and improves the usability.

[0062] As Figure 4 、 Figure 6 、 Figure 9 As shown in the figure, the limiting structure includes a limiting protrusion 21 provided on the upper end surface of the box body 2 and protruding towards the cushion 5. Among them, a placement groove 30 is provided at the upper end of the box body 2 for placing the cushion 5. The placement groove 30 is recessed towards the bottom of the box body 2, and the width of the placement groove 30 is smaller than the length of the box body 2. As a result, the side of the upper end of the box body 2 protrudes relative to the placement groove 30. When the cushion 5 is placed on the placement groove 30, it can limit the side of the cushion 5 and further prevent the cushion 5 from shifting, improving the safety of use; the limiting protrusion 21 is provided at the middle position of the end surface of the placement groove 30. The installation structure of the cushion 5 includes a locking groove 22 that cooperates with the limiting protrusion 21. The locking groove 22 is recessed in the direction away from the box body 2, and the shape of the locking groove 22 is adapted to the structure of the limiting protrusion 21. When the cushion 5 is placed in the placement groove 30, the limiting protrusion 21 is located in the locking groove 22, and the limiting protrusion 21 plays a guiding and locking role for the cushion 5. With the cooperation of the placement groove 30 and the limiting protrusion 21, the horizontal displacement and the vertical downward displacement of the cushion 5 are both limited. When a child sits on the cushion 5, the stability of the cushion 5 can be ensured, and the cushion 5 will not be easily displaced, guaranteeing the safety of use of the luggage case 1; one end of the limiting protrusion 21 away from the connecting rod 6 protrudes upward by a certain height, then extends towards the connecting rod 6 direction and is connected to the upper end surface of the placement groove 30. The inside of the limiting protrusion 21 is hollowed out, which can reduce the weight and manufacturing cost.

[0063] A further description of the unlocking mechanism 7 is as follows; as Figure 6 、 Figure 10As shown, an unlocking groove 8 is provided on the connecting seat 4. The unlocking mechanism 7 is arranged inside the seat cushion 5. The unlocking mechanism 7 is located at the middle position of the seat cushion 5. One end of the unlocking mechanism 7 close to the connecting seat 4 is located inside the unlocking groove 8. Both ends of the seat cushion 5 are rotatably connected to the connecting seat 4. The unlocking mechanism 7 is movably connected to the connecting seat 4. The unlocking mechanism 7 is arranged along the front-back direction of the seat cushion 5. An unlocking opening 9 is provided on the seat cushion 5. The unlocking opening 9 is open on the upper end surface of the seat cushion 5. One end of the unlocking mechanism 7 far from the connecting seat 4 passes through the unlocking opening 9 and is exposed outside the upper end surface of the seat cushion 5. The user can pull the exposed unlocking mechanism 7, and the unlocking mechanism 7 drives the seat cushion 5 to displace, so that the seat cushion 5 is disengaged from the locking with the box body 2 to achieve unlocking.

[0064] Specifically, as Figures 6 to 10 shown, the seat cushion 5 includes an upper seat board 17 and a lower seat board 18. The upper seat board 17 is connected to the lower seat board 18. An installation cavity for placing the unlocking mechanism 7 is formed between the upper seat board 17 and the lower seat board 18. Among them, the unlocking opening 9 is provided on the upper seat board 17. The unlocking opening 9 is located at the front end of the seat cushion 5. The unlocking opening 9 is open on the upper and lower end surfaces of the upper seat board 17. As Figure 6 shown, an opening for the unlocking mechanism 7 to pass through is provided at the rear end where the upper seat board 17 is connected to the lower seat board 18. The rear end of the unlocking mechanism 7 enters the unlocking groove 8 of the connecting seat 4 through this opening. The unlocking mechanism 7 can freely enter and exit the unlocking groove 8.

[0065] The unlocking mechanism 7 includes a pulling member 10, an elastic member 11 and a sliding member 12. As Figure 8As shown, the rear end of the sliding member 12 is provided with an outwardly protruding insertion portion 29. The insertion portion 29 is inserted into the unlocking groove 8 to achieve connection with the connecting seat 4. A sliding groove is provided in the middle of the sliding member 12, and the sliding groove penetrates through the upper and lower end faces of the sliding member 12. A limiting convex block is provided on the upper seat plate 17 or the lower seat plate 18, and the limiting convex block protrudes toward the sliding member 12 and enters the sliding groove, thereby limiting the sliding of the sliding member 12 to prevent the sliding member 12 from sliding without limitation. In this application, the length extension direction of the sliding groove is the sliding direction of the sliding member 12, and the sliding member 12 can slide between the unlocking opening 9 and the unlocking groove 8, that is, the sliding member 12 slides along the front-back direction of the box body 2. The front end of the sliding member 12 is provided with a mounting portion, and a support rod is mounted on the mounting portion. The pulling member 10 is sleeved on the support rod, thereby realizing the connection between the pulling member 10 and the sliding member 12. One end of the pulling member 10 away from the sliding member 12 passes through the unlocking opening 9 and is exposed outside the seat cushion 5. The user pulls the pulling member 10 exposed outside the seat cushion 5 and applies a vertical force to the pulling member 10. Through the transmission of the pulling member 10, it is converted into a force acting on the sliding member 12 in the sliding direction, so that the sliding member 12 can be pulled to slide. After the sliding member 12 moves to a certain position and stops moving, the force of the pulling member 10 acts on the upper seat plate 17, thereby driving the seat cushion 5 to move in the vertical direction (the direction of the force applied to the pulling member 10), and unlocking the lock between the seat cushion 5 and the box body 2, so as to facilitate the unlocking of the whole frame 3 and the box body 2.

[0066] Further, Figure 6 、 Figure 7 As shown, when the unlocking mechanism 7 is in a natural state, the limiting convex block is located at the front end part of the sliding groove. The limiting convex block plays a limiting role and a guiding role for the sliding member 12. The elastic member 11 is located in the sliding groove, and the elastic acting force direction of the elastic member 11 is parallel to the sliding direction of the sliding member 12. The front end of the elastic member 11 is in contact with the limiting convex block, and the rear end is in contact with the inner rear wall of the sliding groove. That is, one end of the elastic member 11 exerts a force on the limiting convex block, and the other end exerts a force on the sliding member 12. With the cooperation of the elastic member 11, the limiting convex block and the sliding member 12, the connection between the sliding member 12 and the seat cushion 5 is a movable connection. After the sliding member 12 moves toward the unlocking opening 9, the elastic member 11 is compressed. When the force of the pulling member 10 disappears, the elastic member 11 generates an elastic acting force to push the sliding member 12 to move toward the connecting seat 4, so that the sliding member 12 has an automatic reset function to ensure the connection stability between the unlocking mechanism 7, the connecting seat 4 and the seat cushion 5, and ensure the unlocking function of the unlocking mechanism 7.

[0067] It should be noted that in this application, the unlocking mechanism 7 may only include the pulling member 10. One end of the pulling member 10 is fixedly connected to the lower seat plate 18, and the other end passes through the unlocking opening 9 and is exposed outside the seat cushion 5. Or the pulling member 10 is fixedly connected to the upper seat plate 17, and by driving the pulling member 10, unlocking can also be achieved. However, the purpose of further providing the pulling member 10 and the elastic member 11 in the unlocking mechanism 7 of this application is that when the unlocking mechanism 7 is pulled, when a force is first applied to the pulling member 10, the force first affects the sliding member 12, and the sliding member 12 moves first. And during the movement of the sliding member 12, it is necessary to overcome the acting force of the elastic member 11, that is, the unlocking force between the seat cushion 5 and the box body 2 increases, and the unlocking time increases, which plays a buffering role in the unlocking of the seat cushion 5 and the box body 2. Compared with the solution of only setting the pulling member 10, when only the pulling member 10 is set, once a force is applied, the unlocking of the seat cushion 5 and the box body 2 is instant and fast. While in the solution of simultaneously setting the sliding member 12 and the elastic member 11, while increasing the magnitude of the unlocking force, the buffering time is also increased, which can prevent the seat cushion 5 and the box body 2 from being immediately unlocked when a child accidentally drives the pulling member 10, improving the safety performance of the unlocking mechanism 7 and reducing the probability of accidents.

[0068] In this application, the pulling member 10 can be set as a rope or a belt, and the pulling member 10 can be set to have elasticity. In this embodiment, it is preferably a belt shape, having a certain width, increasing the force-bearing surface with the sliding member 12 and the upper seat plate 17, reducing the pressure at the force-bearing point, being beneficial to pulling the seat cushion 5, reducing wear, and improving the service life. As Figure 9 shown, the pulling member 10 includes a base portion 19 and a limiting portion 20. The thickness of the base portion 19 is less than the inner diameter of the unlocking opening 9, the outer diameter of the limiting portion 20 is greater than the inner diameter of the unlocking opening 9, the thickness of the limiting portion 20 is greater than the thickness of the pulling member 10, and the limiting portion 20 is arranged inside the seat cushion 5, that is, the limiting portion 20 is located below the unlocking opening 9. When the pulling member 10 is driven and the limiting portion 20 is about to enter the unlocking opening 9, since the thickness of the limiting portion 20 is greater than the inner diameter of the unlocking opening 9, therefore, after the pulling member 10 is pulled a certain distance, the pulling member 10 is fixed relative to the upper seat plate 17, and the pulling member 10 will stop extending outwards, that is, the sliding of the sliding member 12 stops, and the limiting portion 20 fits with the side wall of the unlocking opening 9, so that the acting force of the pulling member 10 on the upper seat plate 17 is concentrated at the position of the limiting portion 20. Since the thickness of the limiting portion 20 is relatively large, the extrusion and wear generated by the acting force between the upper seat plate 17 and the limiting portion 20 will not affect the use of the pulling member 10, increasing the durability and service life of the pulling member 10.

[0069] Furthermore, the sliding member 12 is further expanded; as Figure 7 、 Figure 8As shown, the sliding groove is divided into a first sliding groove 13 and a second sliding groove 14. The first sliding groove 13 and the second sliding groove 14 are arranged in parallel at intervals. Among them, the length of the second sliding groove 14 is less than that of the first sliding groove 13. There are two second sliding grooves 14, which are symmetrically arranged on both sides of the first sliding groove 13. The rear ends of the second sliding groove 14 and the first sliding groove 13 are flush; the elastic member 11 is arranged in the first sliding groove 13; as Figure 7 shown, the limiting bump is cylindrical. The limiting bump is arranged on the lower seat plate 18. The limiting bump is divided into a first limiting bump 15 and a second limiting bump 16. The first limiting bump 15 is located in the first sliding groove 13, and the second limiting bump 16 is located in the second sliding groove 14, so as to realize the limitation of the first sliding groove 13 and the second sliding groove 14; the arrangement of the second sliding groove 14 limits the sliding length of the sliding member 12, avoiding the excessive sliding of the sliding member 12; at the same time, the symmetrical arrangement of the two second sliding grooves 14 also increases the force uniformity of the sliding member 12 being limited, enabling the sliding member 12 to slide smoothly, thus ensuring the unlocking stability of the unlocking mechanism 7.

[0070] Furthermore, as Figure 8 shown, limiting plates are provided on both the upper end surface and the lower end surface of the first sliding groove 13 to limit the upper and lower positions of the elastic member 11, ensuring the stability of the elastic member 11 in the first sliding groove 13 and preventing the elastic member 11 from being easily displaced up and down.

[0071] Furthermore, as Figures 1 to 3 、 Figure 5 shown, the baby stroller suitcase 1 further includes a backrest mechanism. The backrest mechanism includes a back pad 24 and a retaining ring 23. The retaining ring 23 is connected to the connecting rod 6, and the retaining ring 23 is located above the seat cushion 5. The retaining ring 23 is of a ring structure. One end of the retaining ring 23 away from the connecting rod 6 is connected to the back pad 24. The back pad 24 is connected to the inner side of the retaining ring 23 and is used to support the back of the child. The back pad 24 and the retaining ring 23 are detachably connected, and the retaining ring 23 and the connecting rod 6 are detachably connected, so that the distance between the retaining ring 23 and the seat cushion 5 can be adjusted to better support the back of the child. In this embodiment, the diameter of the retaining ring 23 is slightly larger than the diameter of the box body 2. The retaining ring 23 can provide comprehensive limitation for the upper body of the child, avoiding the child from tipping over. The backrest mechanism not only improves the safety protection for the child but also increases the comfort of the child's use.

[0072] Furthermore, as Figure 2As shown, the baby strolling suitcase 1 further includes a decorative block 25, which can be composed of different patterns and colors. A connecting portion 26 is provided on the surface of the box body 2. Among them, the connecting portion 26 can be a magnetic strip or a magic tape. The decorative block 25 is detachably connected to the box body 2 through the connecting portion 26, so that users can replace different decorative blocks 25, thereby adding interesting interactivity to the box body 2, improving the aesthetic appearance of the box body 2 during use, increasing children's acceptance of the baby strolling suitcase 1, and enhancing the parent-child interaction effect.

[0073] In addition, as Figure 1 , Figure 2 shown, a handle 27 is provided at the upper end of the connecting rod 6.
