Technical Field

[0001] The present application relates to the technical field of luggage cases, and in particular to a foldable trolley case. Background Art

[0002] Luggage, also known as a suitcase or trolley case, is a box used to carry belongings and is an essential item for daily travel and business trips. However, currently, the size of luggage cannot be controlled, making it inconvenient to check in. Despite the fact that luggage is essential for daily travel and business trips, existing luggage on the market is fixed in size and bulky.

[0003] Publication number CN100415136C discloses a foldable luggage case comprising a foldable wall and first and second shielding surfaces, the first and second shielding surfaces being connected to the periphery of the wall. A pull rod and caster assembly are rigidly and detachably connected to the wall to form a supporting structure for the case. To fold, the suitcase is first detached from the connections between some of the surfaces before folding, resulting in a smaller volume.

[0004] Before folding, the above-mentioned suitcase needs to manually disassemble the structure of the connection between some surfaces and then fold it. After folding, the volume of the suitcase is reduced, but the area in the longitudinal direction of the suitcase remains unchanged, which requires improvement. Summary of the Invention

[0005] In order to reduce the area and volume of the suitcase after folding, thereby reducing the space occupied by the suitcase, the present application provides a foldable trolley case.

[0006] The present application provides a foldable suitcase, which adopts the following technical solution:

[0007] A foldable trolley case includes a storage bag, a first base and a second base, there is a gap between the first base and the second base, the first base and the second base are both located on the bottom wall of the storage bag, a sliding sleeve is installed on the side wall of the first base, an abutment rod is slidably connected to the inner wall of the sliding sleeve, a driving rod is rotatably connected to the first base, the abutment rod is rotatably connected to the driving rod, there is a distance between the abutment rod and the rotating part of the driving rod, and a driving component for driving the driving rod to rotate is provided on the side wall of the first base.

[0008] By adopting the above technical solution, the storage bag is made of foldable nylon or Oxford cloth, the driving component drives the driving rod to rotate, and the abutment rod slides under the traction of the traction piece and the sliding of the sliding sleeve, and the abutment rod supports the gap between the first base and the second base, so that the support strength of the suitcase is stronger. At this time, the user puts the luggage items into the suitcase; when the suitcase needs to be folded, the driving component drives the driving rod to rotate, so that the abutment rod slides to the first base, and the suitcase can be folded at this time, pushing the first base and the second base closer, and the storage bag is attached to the first base and the second base, thereby reducing the volume of the suitcase while reducing the area of ​​the suitcase, thereby reducing the space occupied by the suitcase during the storage process.

[0009] Optionally, a connecting rod is fixed on the outer wall of the driving rod, a first support rod is fixed on the outer wall of the connecting rod, a second support rod is rotatably connected to the outer wall of the second base, and a linkage assembly for driving the first support rod and the second support rod to rotate is provided on the outer wall of the first support rod.

[0010] By adopting the above technical solution, the first support rod and the second support rod are set to support the inner wall of the storage bag, so that the storage bag appears to be more upright, reducing the possibility of the storage bag being deformed due to the support of the items in the storage bag. The driving rod is rotated, and the first support rod and the second support rod are rotated under the action of the linkage assembly, so that when the abutment rod slides between the first base and the second base, the first support rod and the second support rod support the inner cavity of the storage bag. When the abutment rod slides onto the first base, the first support rod rotates toward the upper surface close to the first base, and the second support rod rotates toward the direction of the second base, which makes it easy to fold the suitcase.

[0011] Optionally, a receiving rod is fixed on the outer wall of the second support rod, and the receiving rod is eccentrically arranged with respect to the rotating shaft of the support rod. The linkage assembly includes a first connecting block hinged to the end of the receiving rod, a second connecting block hinged to the end of the connecting rod, a traction rod connecting the first connecting block and the second connecting rod, and a return piece fixed to the end of the first connecting block away from the receiving rod, one end of the return piece is fixedly connected to the first connecting block, and the other end is fixedly connected to the second connecting block, and the traction rod is slidably connected to the first connecting block and the second connecting block.

[0012] By adopting the above technical solution, the receiving rod is driven to rotate in the process of rotating the driving rod, and the receiving rod drives the first connecting block to move, drives the traction rod to move, drives the second connecting block to move, thereby driving the second support rod to rotate. After the suitcase is folded, the return part is in a compressed state. When the user unfolds the suitcase, the return part makes it easier to unfold the suitcase.

[0013] Optionally, the driving assembly includes a driving rod rotatably connected to the first base, a worm coaxially fixed to the outer wall of the driving rod and a worm wheel coaxially fixed to the end of the connecting rod, the worm wheel is engaged with the worm, the first connecting block is eccentrically arranged with the worm wheel, and a switch component for controlling the rotation of the driving rod is provided on the first base.

[0014] By adopting the above technical solution, the switch component drives the driving rod to rotate, the driving rod drives the worm to rotate, the worm engages with the worm wheel, drives the first connecting block to move, and thus drives the traction rod to move.

[0015] Optionally, the switch component includes a rotating handle rotatably connected to the first base, and the rotating handle is coaxially fixed to the driving rod.

[0016] By adopting the above technical solution, the user rotates the rotating handle to drive the driving rod to rotate, thereby driving the worm to rotate.

[0017] Optionally, a partition is fixed on the inner wall of the storage bag, one side of the partition is fixedly connected to the inner wall of the storage bag, and a zipper is fixed at the edge of the partition, and the zipper is fixedly connected to the inner wall of the storage bag.

[0018] By adopting the above technical solution, the setting of the partition separates the inner cavity of the storage bag from the first base, reducing the possibility of the items in the storage bag contacting the abutment rod, and plays a role in blocking external impurities, reducing the possibility of external impurities entering between the first base and the second base, causing difficulties for users to clean up the impurities.

[0019] Optionally, the first support rod includes a protective cover and a resilient member installed in the protective cover, both ends of the resilient member abut against the inner wall of the protective cover, and the second support rod and the first support rod are made of the same structure.

[0020] By adopting the above technical solution, when the first support rod is subjected to external force, the rebound member will bend, thereby causing the first support rod to bend and play a buffering role. When the user accidentally falls during travel, the support rod bends, protecting the user and reducing the possibility of the user being injured. Under the action of the rebound member's own rebound force, the first support rod and the second support rod can return to their original positions.

[0021] Optionally, several mounting shells are fixed on the outer wall of one end of the first base away from the second base, the mounting shells are located outside the storage bag, a mounting shaft is fixed on the inner wall of the mounting shell, a roller is rotatably connected to the outer wall of the mounting shaft, and the edge of the roller is located outside the mounting shell.

[0022] By adopting the above technical solution, the setting of the mounting shell facilitates the fixation of the roller. When the staff pushes the suitcase, the roller rotates around the mounting axis and rolls on the ground, making it convenient for the staff to carry the suitcase.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The possibility of the first base and the second base being close to each other is limited by the abutment of the abutment rod. At this time, the user puts the items to be carried into the storage bag; when the user needs to fold the suitcase, the driving assembly drives the driving rod to rotate, and the driving rod drives the abutment rod to slide on the sliding sleeve. At this time, the first base can slide toward the second base. The storage bag is made of nylon or Oxford cloth. The user presses the storage bag onto the first base and the second base. The proximity of the first base and the second base reduces the length of the suitcase, and the attachment of the storage bag to the first base reduces the distance in the height direction of the suitcase, thereby reducing the space occupied by the suitcase and making it more convenient to store the suitcase.

[0025] 2. The driving rod drives the abutment rod to slide, thereby driving the first support rod to rotate. The arrangement of the first support rod and the second support rod supports the inner wall of the storage bag, making the outer wall of the storage bag more upright, reducing the possibility of deformation of the outer wall of the storage bag under squeezing, and causing damage to the items in the storage bag; when the abutment rod slides toward the first support rod, the first support rod rotates toward the first base, thereby reducing interference with the folding of the suitcase.

[0026] 3. The first support rod includes a resilient member and a protective cover wrapped around the outer wall of the resilient member, so that the first support rod will bend when subjected to external force, and the first support rod will return to its original state under the action of the elastic force of the elastic member itself. The elastic first support rod has a certain buffering effect, reducing the damage caused by the user after falling; the second support rod and the driving rod both adopt the same structure as the first support rod.
