Description

Technical Field

[0001] The present invention relates to the field of luggage cases, and in particular to a supporting structure of an intelligent luggage case. Background Art

[0002] Smart luggage integrates advanced technologies, aiming to provide users with a more convenient, safe, and efficient travel experience. This is especially true for mobile smart luggage, which allows users to sit directly on the luggage while moving, reducing the physical burden. Therefore, the suitcase's strength directly impacts the user experience.

[0003] Existing smart luggage cases that can be driven include a case body, a driving handle, and a pull rod. The driving handle and the pull rod are respectively arranged on both sides of the top of the case body, and rollers are rotatably installed on the bottom of the case body. When a user sits on the case body, the load is only carried by the case body and the rollers. If the strength of the case body is insufficient, the load-bearing capacity will be insufficient, and the case body may be easily crushed. Summary of the Invention

[0004] In order to improve the bearing strength of a smart suitcase, the present application provides a support structure for a smart suitcase.

[0005] The support structure of a smart luggage provided in this application adopts the following technical solution:

[0006] A support structure for a smart suitcase includes a telescopic pull rod, a fixed seat, and a pair of rollers. The telescopic pull rod is used to be installed on the side of the suitcase body away from the driving handle; the fixed seat is arranged directly below the telescopic pull rod, and the bottom end of the telescopic pull rod is fixedly connected to the fixed seat via a fastener; and the two rollers are rotatably mounted on both sides of the fixed seat.

[0007] By adopting the above technical solution, when the user sits on the suitcase, he or she is located on the side of the suitcase away from the driving handle, that is, the side where the telescopic pull rod is provided; therefore, the telescopic pull rod, the fixing seat and the roller are interconnected to form a whole, thereby improving the strength of the user's sitting position; the pressure applied by the user to the suitcase is applied to the roller via the telescopic pull rod and the fixing seat, and the force applied to the suitcase itself will be greatly reduced, thereby achieving protection of the suitcase.

[0008] Preferably, a pair of telescopic pull rods are provided, and the two telescopic pull rods are spaced apart along the width direction of the box body.

[0009] By adopting the above technical solution, the support area can be increased and the support strength can be further improved.

[0010] Preferably, the telescopic pull rod includes an outer tube and a telescopic rod, and the telescopic rod is slidably installed in the outer tube; a connecting rod is provided at the bottom ends of the two telescopic pull rods, and the bottom ends of the two outer tubes of the two telescopic pull rods are fixedly connected to the connecting rod; a handle is connected between the tops of the two telescopic rods of the two telescopic pull rods.

[0011] By adopting the above technical solution, the bottom ends of the telescopic pull rods are connected by the connecting rod, and the top ends are connected by the handle, so that the telescopic pull rods are connected as a whole, further improving the supporting strength.

[0012] Preferably, it also includes a receiving groove preset in the box body for receiving the handle, and a avoidance hole is opened at the bottom of the receiving groove and at a position corresponding to the top of the outer tube. The avoidance hole is located close to the groove wall of the receiving groove, and the bottom end of the groove wall of the receiving groove abuts against the top of the outer tube.

[0013] By adopting the above technical solution, since the bottom end of the groove wall of the accommodating groove abuts against the top end of the outer tube, the strength of the user's sitting position in the box can be improved through the existing structural design.

[0014] Preferably, a positioning cylinder is installed at the position of the connecting rod corresponding to the outer cylinder, and the bottom end of the outer cylinder is plugged into the positioning cylinder.

[0015] By adopting the above technical solution, the design of the positioning cylinder makes the installation of the outer cylinder on the connecting rod more stable.

[0016] Preferably, the fastener includes a fastening bolt, which is passed through the connecting rod and threadedly mounted on the fixing seat.

[0017] By adopting the above technical solution, the connecting rod and the fixing seat can be fixedly connected by directly passing the fastening bolt through the connecting rod and then threadedly installed on the fixing seat. This connection method is simple and has high strength.

[0018] Preferably, the fixing seat is provided with a connecting tube at a position corresponding to each of the fastening bolts, and the fastening bolts are threadedly installed in the corresponding connecting tube; and a positioning ring for the connecting tube to be clamped is provided at a position of the connecting rod corresponding to the connecting tube.

[0019] By adopting the above technical solution, during installation, the connecting tube is directly inserted into the positioning ring, and then the fastening bolt is passed through the connecting rod and screwed into the connecting tube, which has high installation efficiency.

[0020] Preferably, a connecting shaft is passed through the fixing seat, two ends of the connecting shaft are respectively passed through the two rollers, and the rollers are rotatably mounted on the connecting shaft.

[0021] By adopting the above technical solution, the two rollers are installed on the same connecting shaft, and the connecting shaft is installed on the fixing seat, so that the fixing seat and the rollers form a whole, thereby improving the supporting stability of the rollers.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. When a user sits on the suitcase, they are on the side away from the travel handle, which is also the side where the telescopic rod is located. Therefore, the telescopic rod, fixed base, and rollers are connected to form a whole, thereby improving the strength of the user's sitting position. The pressure applied by the user to the suitcase is applied to the rollers through the telescopic rod and fixed base, greatly reducing the force applied to the suitcase itself, thereby achieving protection for the suitcase.

[0024] 2. Since the bottom end of the groove wall of the receiving groove abuts against the top end of the outer tube, the existing structural design can improve the strength of the user's sitting position in the box;

[0025] 3. The two rollers are installed on the same connecting shaft, and the connecting shaft is installed on the fixed seat, so that the fixed seat and the roller form a whole, improving the support stability of the roller. BRIEF DESCRIPTION OF THE DRAWINGS
