Description

Technical Field

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

[0002] At present, luggage is an indispensable item in travel and daily life. The evolution of its function and design is always closely linked to people's needs. Therefore, the intelligent luggage that can be driven has come into being. The intelligent luggage has the ability to move autonomously. It usually has a built-in driving device. When the user sits on it, it can move with the user and reduce the burden on the user.

[0003] Since the drivable smart suitcase can be sat on by users, the materials of the smart suitcase are generally produced with relatively high-strength materials as raw materials. High-strength materials (such as aluminum) generally require high-cost processing to form grooves, which results in the handles, wheels, etc. of the suitcase only being exposed outside the suitcase body, making the suitcase look like a car rather than a suitcase. In addition, it is easy for suitcases of the same size to have their contents space greatly reduced due to the space occupied by the wheels and handles, thereby greatly reducing the practicality of the suitcase. Summary of the invention

[0004] In order to increase the content space of the smart suitcase while ensuring the overall strength of the smart suitcase, the present application provides a smart suitcase.

[0005] The present application provides a smart luggage, which adopts the following technical solution: A smart luggage case comprises a case body, a back side plate and a front side plate, wherein the case body is formed by integral injection molding, rollers are rotatably mounted at both ends of the bottom of the case body, and a driving mechanism for driving the rollers to rotate is mounted in the case body; both sides of the case body are open, and the back side plate and the front side plate are respectively mounted on both sides of the opening of the case body; a pulling telescopic rod and a traveling telescopic rod are respectively mounted on both sides of the case body in a forward direction, and the case body is concavely provided with accommodating grooves corresponding to the handles of the pulling telescopic rod and the handles of the traveling telescopic rod; a fixing seat is mounted in the case body at a position directly below the pulling telescopic rod, and the bottom end of the pulling telescopic rod is fixedly connected to the fixing seat by a first fastener; and the rollers are rotatably mounted at both sides of the fixing seat.

[0006] By adopting the above technical solution, when the user sits on the suitcase, the user will sit at a position away from one end of the traveling telescopic rod, that is, at a position corresponding to the position of pulling the telescopic rod; because the telescopic rod, the fixing seat and the roller are interconnected to form a whole, the pressure applied by the user to the suitcase is applied to the roller through the telescopic rod and the fixing seat, and the force applied to the suitcase itself will be greatly reduced, thereby improving the strength of the position where the user sits; therefore, even if the suitcase is formed by integral injection molding, the strength of the position where the user sits can be guaranteed, and at the same time, under the condition of the same overall suitcase occupation area, the content space of the suitcase is improved.

[0007] Preferably, a pair of telescopic pulling rods are provided, and the two telescopic pulling rods are spaced apart along the width direction of the box body; a connecting rod is provided at the bottom ends of the two telescopic pulling rods, and the bottom ends of the two outer tubes of the two telescopic pulling rods are fixedly connected to the connecting rod; a avoidance hole is provided at the bottom of the accommodating groove corresponding to the handle of the telescopic pulling rod, and the avoidance hole is provided at a position corresponding to the top end of the telescopic pulling rod, and the avoidance hole is located close to the groove wall of the accommodating groove, and the bottom end of the groove wall of the accommodating groove abuts against the top end of the outer tube of the telescopic pulling rod.

[0008] By adopting the above technical solution, a pair of telescopic rods are provided, thereby increasing the support area and further improving the support strength; since the bottom end of the groove wall of the accommodating groove abuts against the top end of the outer tube of the telescopic rod, the strength of the user's sitting position in the box can be improved through the existing structural design, and no reinforcing structure is added as a whole, thereby reducing the overall cost.

[0009] 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.

[0010] 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.

[0011] Preferably, it also includes a first fixing frame, a lining, a cover plate and a second fastener, wherein the first fixing frame extends circumferentially along the opening of the box body, and the first fixing frame is connected to the opening of the box body corresponding to the front side plate; the first fixing frame is provided with a snap-in groove extending circumferentially, the edge of the lining is snapped into the snap-in groove, and the cover plate is covered at the notch of the first fixing frame corresponding to the snap-in groove; the second fastener is used for synchronously and detachably installing the first fixing frame and the cover plate on the box body; the front side plate is covered on the side of the box body corresponding to the cover plate away from the first fixing frame.

[0012] By adopting the above technical solution, the edge of the lining is first inserted into the locking groove, and then the cover plate is set at the notch of the locking groove. Finally, the first fixing frame and the cover plate are detachably installed on the box body through the second fastener, so that the edge of the lining is stabilized in the locking groove, thereby fixing the lining, facilitating installation, and having high processing efficiency. When damage occurs during use and needs to be repaired, the second fastener is directly used to loosen the restraint on the fixing block and the cover plate, and then the lining can be directly taken out and replaced separately, so that the repair difficulty is lower than that of sewing.

[0013] Preferably, the first fixed frame includes a positioning section and a connecting section, the positioning section extends in a direction parallel to the top wall of the box body, one end of the connecting section is connected to one end of the positioning section, and the other end of the connecting section extends in the direction of the box body, and the positioning groove is provided in the connecting section; one end of the positioning section away from the connecting section is bent to have a plug-in portion for inserting the edge of the box body.

[0014] By adopting the above technical solution, when installing the first fixing frame, the edge of the box body is inserted into the plug-in portion, which plays an initial positioning role for subsequent connection through the second fastener; and the thickness can also be increased, thereby improving the overall strength.

[0015] Preferably, a positioning rod is installed at a position of the first fixing frame located in the positioning groove, and the positioning rod extends in the length direction of the positioning groove. The positioning rod is used for the edge of the lining to be wound around, and there is a gap between the cover plate and the positioning section for the edge of the lining to be clamped in after the positioning rod is wound around.

[0016] By adopting the above technical solution, the edge of the lining is wrapped around the positioning rod, and then the positioning rod is inserted into the positioning groove, so that the edge of the lining can be inserted into the positioning groove; then the cover plate is placed on the connecting section, which not only stabilizes the positioning rod in the positioning groove, but also clamps the edge of the lining after wrapping around the positioning rod through the gap, thereby completing the positioning of the lining, thereby further improving the processing efficiency and ensuring the installation strength of the lining.

[0017] Preferably, the second fastener includes a first fastening bolt, and a plurality of the first fastening bolts are arranged at intervals along the extension direction of the first fixing frame. The first fastening bolt is sequentially passed through the lining, the cover plate and the first fixing frame and then threadedly installed on the box body.

[0018] By adopting the above technical solution, after the cover plate is installed, the first fastening bolt is directly passed through the lining, the cover plate and the first fixing frame in sequence and then threadedly installed on the box body, which can not only fix the cover plate and the fixing block, but also further fix the lining; when the lining needs to be replaced, the first fastening bolt can be directly unscrewed, and the maintenance difficulty is low.

Compared with the method of assembling by rivets using high-strength materials, the user's experience of sitting on the suitcase is improved; in addition, since the structure of the second fixing frame is consistent with that of the first fixing frame, mass production and processing can be achieved, and the positioning buckle corresponding to the back panel plays a role in fixing the second fixing frame, while the positioning buckle corresponding to the front panel plays a role in limiting the positioning rod in the positioning groove; the positioning groove corresponding to the back panel plays a role in limiting the back panel, while the positioning groove corresponding to the front panel plays a role in installing the positioning rod; the overall processing cost is greatly reduced.

[0021] Preferably, the third fastener comprises a connecting bolt, and the connecting bolt is passed through the second fixing frame and threadedly mounted on the box body.

[0022] By adopting the above technical solution, the installation of the second fixing frame is simple and stable.

[0024] By adopting the above technical solution, the fastening strip not only achieves the function of connecting the first fastening bolt and the connecting bolt to the box body, but also can enhance the structural strength of the box body while ensuring the lightness of the box body itself.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. When the user sits on the suitcase, the user will sit at a position far away from the end of the telescopic rod, that is, at the position corresponding to the pulling of the telescopic rod; because the telescopic rod, the fixing seat and the roller are connected to form a whole, the pressure applied by the user to the suitcase is applied to the roller through the telescopic rod and the fixing seat, and the force applied to the suitcase itself will be greatly reduced, thereby improving the strength of the user's sitting position; therefore, even if the suitcase is formed by injection molding, the strength of the user's sitting position can be guaranteed, and at the same time, the content space of the suitcase is improved under the same overall suitcase occupation area; 2. Since the bottom end of the groove wall of the receiving groove abuts against the top end of the outer tube of the pulling telescopic rod, the strength of the user's sitting position in the box can be improved through the existing structural design, and no reinforcement structure is added as a whole, thereby reducing the overall cost; 3. When damage occurs during use and needs to be repaired, the second fastener is used to loosen the restraints on the fixed block and the cover plate, and then the lining is directly taken out and replaced separately, so the repair difficulty is lower than that of sewing; 4. When installing the back side panel, directly place the back side panel cover at the opening on the side of the box body away from the front side panel, and insert the positioning buckle into the positioning hole to complete the positioning installation of the back side panel, so that no rivet structure can be seen from the appearance after installation. Compared with the method of assembling with high-strength materials through rivets, it improves the user's experience of sitting on the suitcase; 5. Since the structure of the second fixed frame is consistent with that of the first fixed frame, mass production and processing can be achieved. The positioning buckles corresponding to the back side panel play a role in fixing the second fixed frame, while the positioning buckles corresponding to the front side panel play a role in limiting the positioning rod in the positioning groove; the positioning grooves corresponding to the back side panel play a role in limiting the back side panel, while the positioning grooves corresponding to the front side panel play a role in installing the positioning rod; the overall processing cost is greatly reduced.
