Description

Technical Field

[0001] This utility model relates to the field of trolley case technology, specifically to a multifunctional trolley case for strollers with children. Background Technology

[0002] A suitcase, also known as a travel case or rolling suitcase, is a box carried when traveling to store belongings; it is a type of luggage. Suitcases are typically used to store clothing, personal care items, and souvenirs needed for a trip. Currently, most suitcases on the market only have the function of carrying luggage. When people travel with children, it is often very inconvenient, and sometimes they have to carry a folding stroller for children, which brings inconvenience to their travels. To solve the above problems, a multi-functional trolley suitcase with a seat (publication number "CN209711854U") is disclosed. It includes a suitcase body, a frame, two large wheels, a seat plate connector, a seat plate, a seat plate button, a telescopic rod, and a pull rod button. The suitcase body and the frame are detachably connected for carrying travel items. The two large wheels are respectively located on both sides of the lower end of the frame for moving the frame and the suitcase body. The seat plate connector is fixedly sleeved in the middle of the frame for connecting the frame and the seat plate. The seat plate is rotatably connected to the seat plate connector for infants and toddlers to sit on. The seat plate button is located on the seat plate for the user to press to combine and separate the frame and the suitcase body. The telescopic rod is located on the upper part of the frame for extending and retracting the frame for easy pushing and pulling. The pull rod button is located at the top of the telescopic rod for the user to press to extend and retract the telescopic rod.

[0003] However, the aforementioned document describes a structure where, when the enclosure is not in use, pressing the seat button lifts the seat up, causing the latches to disengage from the enclosure and separating it from the frame. However, it does not disclose the specific structure of how the frame separates from the enclosure. Furthermore, existing technology has been found to cause the enclosure to tip over easily when the user presses the button with one hand and lifts the seat with the other, as the seat's locking mechanism disappears. This results in both hands being occupied, making it difficult to quickly remove the enclosure and potentially causing confusion and cumbersome steps during disassembly. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a multifunctional baby stroller suitcase that improves the ease of use, addressing the shortcomings of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional stroller suitcase, comprising a suitcase body and a frame detachably mounted on the suitcase body. Two large wheels are provided on both sides of the lower end of the frame. A seat plate connecting part is provided on the frame, and a telescopic pull rod is slidably mounted on the seat plate connecting part. The seat plate connecting part is characterized by: an integrally formed seat plate; the seat plate includes a housing and a first pressing member slidably mounted laterally on the top of the housing; a first locking member is slidably mounted on the bottom of the housing through a through hole; and a first linkage member is provided at the bottom of the first pressing member, enabling the first locking member to extend out of and retract from the housing, thereby causing the first locking member to combine or separate from the suitcase body.

[0006] The above technical solution is adopted: By setting the first pressing part, when the user needs to separate the frame from the box, he only needs to press the first pressing part, which will drive the first linkage part to cause the first locking part to retract into the shell, and the box can be disassembled. Moreover, the design of this structure allows the user to press the first pressing part with one hand and move the box out with the other hand, which is convenient to use and the disassembly steps are simple.

[0007] A further feature of this invention is that: the housing has an installation cavity for mounting the first pressing member, the first linkage member, and the first locking member; a connecting post is provided in the middle of the installation cavity; a first elastic member is provided between the connecting post and the first linkage member; a pressing part is provided opposite to the end of the first linkage member near the first locking member; the pressing part is inclined; a linkage part is provided opposite to the top of the first locking member and abuts against the inclined surface of the pressing part; and a second elastic member is provided between the first locking member and the connecting post.

[0008] The above technical solution is adopted: During use, the first pressing member is pressed to drive the first linkage member to move laterally in the mounting cavity. At this time, the first elastic member is compressed. At the same time, the linkage part on the first locking member is set at an angle due to the squeezing part, so that the first locking member moves vertically upward and retracts into the housing and compresses the second elastic member, thereby separating it from the housing. Conversely, when the first pressing member is released, the force that compresses the first elastic member and the second elastic member disappears, so that the first linkage member and the first locking member are reset, and the first locking member extends out of the housing, thereby realizing the locking function.

[0009] A further feature of this invention is that: a first pressing groove is provided on the top of the housing at the first pressing member, and a pressing auxiliary groove is provided on the top of the housing corresponding to the first pressing groove.

[0010] The above technical solution is adopted: the setting of the first pressing groove makes it easy for the user's fingers to insert and press, and the setting of the pressing auxiliary groove, together with the first pressing groove, makes the structure more ergonomic. The user's index and middle fingers are located in the pressing auxiliary groove, which makes it easier and less strenuous for the user's thumb to apply force to the first pressing part.

[0011] A further feature of this invention is that: a rear support is rotatably provided at both ends of the seat plate connecting part; two small wheels are provided on both sides of the lower end of the rear support; when the rear support is unfolded, it forms a triangular support structure with the lower part of the frame and the ground; and a rear support button assembly is provided on the seat plate connecting part to lock and unlock the rotation of the rear support.

[0012] The above technical solution employs large and small wheels to drive the rear support, frame, and case. Preferably, both large and small wheels are omnidirectional casters, allowing users to easily turn the case at any time. When the rear support is unfolded, it forms a triangular support structure with the lower part of the frame and the ground, ensuring the stability of the rear support after unfolding. This allows children to sit stably on the seat when the user pulls the suitcase. Furthermore, the rear support button assembly allows the user to unfold and retract the rear support by pressing it.

[0013] A further feature of this invention is that the rear support button assembly includes a second pressing member slidably disposed on the seat plate connecting part. Two second pressing members are arranged opposite each other, and a third elastic member is provided between the second pressing members. A second locking member is provided on the ends of the second pressing members that are far apart from each other. Locking blocks are provided at the hinge points on both sides of the upper end of the rear support and the seat plate connecting part. The locking blocks are provided with a plurality of locking grooves along their circumference that can engage with the second locking members.

[0014] The above technical solution is adopted as follows: During use, by pressing the second pressing member, the two are brought close to each other. At this time, the third elastic member is compressed and drives the second locking member to disengage from the locking groove, so that the rear bracket can rotate relative to the seat plate connection part, thereby realizing the unfolding and storage of the rear bracket. When the rear bracket is unfolded or stored and rotated to a certain position, the second pressing member is released, and the third elastic member drives the second locking member to reset and re-lock with the locking groove, so that the rear bracket can no longer rotate, thus completing the locking.

[0015] A further feature of this invention is that a second pressing groove is provided at the top of the seat plate connecting part corresponding to the second pressing member.

[0016] The above technical solution allows users to easily insert their fingers to press the second pressing groove, ensuring effective use.

[0017] A further feature of this invention is that: a frame support is provided at the bottom of the frame, two large wheels are located on the outer sides of both ends of the frame support, and two small wheels are located on the inner sides of both ends of the frame support, and can be partially or completely hidden inside the frame support.

[0018] The above technical solution allows the small wheels to be partially or completely hidden inside the frame support when the rear frame is folded up, thus improving the aesthetics.

[0019] A further feature of this invention is that the back of the housing is provided with a groove that mates with the frame and the rear support, so that the frame and the rear support can be folded up to fit the back of the housing. The top of the housing is also provided with a combination groove that engages with the first locking member.

[0020] The above technical solution is adopted: by setting the box groove and the combination groove, the frame and the rear support can be folded up and fit against the back of the box, and the combination groove cooperates with the first locking part to complete the combination and separation between the box and the frame, so as to realize the detachable function.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Attached Figure Description

The seat plate connecting part 3 is integrally formed with a seat plate 31. The seat plate 31 includes a housing 311 and a first pressing member 312 that is slidably mounted laterally on the top of the housing 311. A first locking member 314 is slidably mounted on the bottom of the housing 311 through a through hole. The bottom of the first pressing member 312 has a first linkage member that can link the first locking member 314 to extend out of the housing 311 and retract the housing 311, thereby causing the first locking member 314 to combine or separate from the suitcase body 1.

[0033] like Figure 3-6The housing 311 shown has a mounting cavity 311a for mounting the first pressing member 312, the first linkage member, and the first locking member 314. A connecting post 311b is provided in the middle of the mounting cavity 311a. A first elastic member 315 is provided between the connecting post 311b and the first linkage member. The first linkage member has a pressing part 313a opposite to the end near the first locking member 314. The pressing part 313a is set at an angle. The top of the first locking member 314 has a linkage part 314a that abuts against the angle of the pressing part 313a. A second elastic member 316 is provided between the first locking member 314 and the connecting post 311b. A connecting cavity for mounting the second elastic member 316 is provided in the connecting post 311b. A first pressing groove 311c is provided at the top of the housing 311 at the first pressing member 312. A pressing auxiliary groove 311d is provided at the top of the housing 311 opposite to the first pressing groove 311c.

[0034] like Figure 1 The seat plate connecting part 3 shown has a rear support 4 rotatably mounted at both ends. The lower end of the rear support 4 has two small wheels 41 on both sides. When the rear support 4 is unfolded, it forms a triangular support structure with the lower part of the frame 2 and the ground. The seat plate connecting part 3 is equipped with a rear support button assembly 32 that can lock and unlock the rotation of the rear support 4.

[0035] like Figure 7-8 The rear support button assembly 32 shown includes a second pressing member 321 slidably disposed on the seat plate connecting part 3. There are two second pressing members 321 arranged opposite each other, and a third elastic member 322 is provided between the second pressing members 321. A second pressing groove 33 is provided on the top of the seat plate connecting part 3 corresponding to the second pressing member 321. A second locking member 323 is provided on the ends of the second pressing members 321 that are far apart from each other. Locking blocks 42 are provided at the hinge points on both sides of the upper end of the rear support 4 and the seat plate connecting part 3. The locking blocks 42 are provided with a plurality of locking grooves 421 along their circumference that can engage with the second locking members 323.

[0036] like Figure 1 The frame 2 shown has a frame support 21 at the bottom. Two large wheels 22 are located on the outer sides of both ends of the frame support 21, and two small wheels 41 are located on the inner sides of both ends of the frame support 21, and can be partially or completely hidden inside the frame support 21. The back of the housing 1 is provided with a groove (not shown in the figure) that cooperates with the frame 2 and the rear support 4, so that the frame 2 and the rear support 4 can be folded up and fit against the back of the housing 1. The back of the housing 1 is also provided with a combination groove (not shown in the figure) that engages with the first locking member 314.

[0037] In use, when the housing 1 needs to be combined or separated from the frame 2, pressing the first pressing member 312 causes the first linkage member to move laterally within the mounting cavity 311a. At this time, the first elastic member 315 is compressed, and simultaneously, due to the inclined surface of the pressing part 313a on the first locking member 314, the first locking member 314 moves vertically upward and retracts into the housing 311, compressing the second elastic member 316, thus separating it from the housing 1. Conversely, releasing the first pressing member 312 removes the force compressing the first elastic member 315 and the second elastic member 316, causing the first linkage member and the first locking member 314 to reset. The first locking member 314 extends out of the housing 311 and engages with the combination groove on the housing 1 to achieve the locking function. At the same time, during use, by pressing the second pressing member 321, the two are brought close to each other. At this time, the third elastic member 322 is compressed, which drives the second locking member 323 to disengage from the locking groove 421, so that the rear bracket 4 can rotate relative to the seat plate connecting part 3, thereby realizing the unfolding and retraction of the rear bracket 4. When the rear bracket 4 is unfolded or retracted to a certain position, the second pressing member 321 is released, and the third elastic member 322 drives the second locking member 323 to reset and re-lock with the locking groove 421, so that the rear bracket 4 can no longer rotate, thus completing the locking.
