Description

Technical Field

[0001] This utility model belongs to the field of luggage technology, specifically relating to a luggage with a concealed handle. Background Technology

[0002] With the popularization of the concept of smart mobility, rideable suitcases are gradually becoming an emerging tool for travel and short-distance commuting. These products typically combine the functions of a suitcase and an electric scooter, satisfying both luggage storage needs and providing the convenience of short-distance riding. However, existing rideable suitcases still have certain limitations in their structural design. For example, to achieve the riding function, the front of the suitcase usually has a retractable handle mechanism and a front wheel assembly, but when retracted, the handle often cannot be completely hidden, and some structures are still exposed outside the suitcase, which not only affects the overall aesthetics but also poses a risk of damage during transportation.

[0003] Currently, some designs attempt to improve the appearance through folding or partial concealment, but complete integration of the pull rod structure with the case body is still not achieved. In most products, the pull rod still protrudes significantly from the top of the case when folded, disrupting the integrity of the case's outline. Exposed mechanical parts are also prone to accumulating dust or accidental impacts. Furthermore, during riding, functional components such as the motor and pull rod base are usually directly exposed, lacking overall aesthetic considerations and failing to meet users' increasingly demanding requirements for product appearance.

[0004] Therefore, it is necessary to design a luggage structure that can completely hide the handle and front wheel assembly, so that the luggage body can maintain the same simple appearance as traditional luggage when not riding, while maintaining visual integrity and aesthetics when riding. Utility Model Content

[0005] To address the above issues, the purpose of this invention is to provide a luggage with a concealed handle, which maintains a simple appearance consistent with traditional luggage when not in use, while also preserving visual integrity and aesthetics when in use.

[0006] The present invention achieves the aforementioned technical effect through the following technical solution: This utility model provides a concealed handle suitcase, comprising: a suitcase body, the front end of which has a recessed receiving cavity; a pull rod handle mechanism, movably disposed at the front end of the suitcase body, including a retractable pull rod assembly and a handle assembly disposed on top of the pull rod assembly; a front wheel assembly, the bottom of which has at least one front wheel, and the pull rod handle mechanism disposed on the front wheel assembly; a telescopic mechanism is provided between the front wheel assembly and the suitcase body, and the pull rod handle mechanism and the front wheel assembly extend or retract into the receiving cavity with the telescopic mechanism.

[0007] Preferably, the pull rod handle mechanism has a decorative panel on the side opposite to the housing, and the outer contour of the decorative panel matches the entrance of the accommodating cavity.

[0008] Preferably, the accommodating cavity has at least one top wall and two opposing side walls, and the lever handle mechanism is concealed within the accommodating cavity under the drive of the telescopic mechanism.

[0009] Preferably, the handle assembly includes a handle base and grip portions symmetrically disposed at both ends of the handle base, the grip portions being rotatably connected to the handle base via a rotating shaft.

[0010] Preferably, a folding arm is provided between the grip and the handle base. The folding arm is connected to the handle base via a hinge, which is located outside the rotation axis. The folding arm can rotate around the hinge to fold or unfold the grip.

[0011] Preferably, the pull rod assembly includes an inner rod, an outer pull rod sleeved outside the inner rod, and a base sleeve sleeved outside the outer pull rod. The handle assembly is fixed to the top of the outer pull rod. The inner rod is connected to the handle assembly through the folding arm. The base sleeve is fixed to the front wheel assembly. The inner rod is driven to move up and down through a drive assembly. The drive assembly includes a motor and a lead screw that is driven by the motor, the lead screw being threadedly connected to the inner rod.

[0012] Preferably, the telescopic mechanism includes a telescopic rod, and the front wheel assembly is fixed to one end of the telescopic rod that extends out of the housing. The telescopic rod moves between a first limit position and a second limit position. When the telescopic rod is in the first limit position, the pull rod handle mechanism and the front wheel assembly extend out of the receiving cavity. When the telescopic rod is in the second limit position, the pull rod handle mechanism and the front wheel assembly retract into the receiving cavity, and the front wheel is located below the housing.

[0013] Preferably, a protective shell is also fitted around the outer periphery of the pull rod assembly. The pull rod assembly is driven to rise and fall by a drive assembly located inside the protective shell. The protective shell is connected to the side of the decorative panel facing the receiving cavity. The height of the protective shell is lower than the height of the decorative panel, and the shape of the protective shell is adapted to the shape of the receiving cavity.

[0014] Preferably, the upper end of the protective shell is provided with recesses on both sides, the recesses being used to accommodate the folded handle assembly.

[0015] Preferably, after the pull rod handle mechanism is concealed within the accommodating cavity under the drive of the telescopic mechanism, the suitcase has a square shape.

[0016] The concealed handle luggage provided by this utility model has the following significant advantages compared with the prior art: 1. Achieve both aesthetic appeal and portability when not in use. The telescopic mechanism retracts the handle and front wheel assembly into the compartment of the suitcase, and the entrance is sealed with a decorative panel, giving the suitcase a neat, square appearance when folded, indistinguishable from a regular suitcase. This design completely avoids the problems of exposed handles in traditional rideable suitcases, such as an abrupt outline, susceptibility to bumps and damage, and inconvenience in transportation, greatly improving the product's aesthetics and ease of daily use.

[0017] 2. Improve the overall aesthetics and structural protection of the riding posture. The protective shell surrounding the pull rod assembly completely conceals the internal precision drive components, such as the motor, lead screw, and base sleeve, when the vehicle is in motion. This not only maintains the clean, streamlined, and high-tech appearance of the luggage compartment while riding, avoiding the cluttered look of exposed mechanical parts, but also effectively prevents dust and water droplets from entering and external impacts from damaging the critical internal mechanisms, thus extending its service life.

Detailed Implementation

[0023] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments. It should be understood that the embodiments described herein are only some, not all, of the embodiments of this utility model, and are merely used to explain the present utility model and are not intended to limit the present utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this utility model will be described in further detail below.

[0025] like Figures 1-4 As shown, this utility model provides a handle-concealed suitcase, comprising: a suitcase body 1, the front end of which has a recessed cavity 3; a pull rod handle mechanism 2, movably disposed at the front end of the suitcase body 1, including a retractable pull rod assembly 5 and a handle assembly 6 disposed on top of the pull rod assembly 5; a front wheel assembly 7, the bottom of which has at least one front wheel 8, and the pull rod handle mechanism 2 is disposed on the front wheel assembly 7; a telescopic mechanism 4 is provided between the front wheel assembly 7 and the suitcase body 1, and the pull rod handle mechanism 2 and the front wheel assembly 7 extend or retract into the cavity 3 with the telescopic mechanism 4. The cavity design provides dedicated space for completely accommodating the pull rod handle mechanism and the front wheel assembly, making the suitcase appear neat and free of protruding parts when not in use, facilitating storage and transportation, while protecting the internal structure from impacts.

[0026] In some specific embodiments, the pull rod handle mechanism 2 has a decorative panel 10 on the side opposite to the housing 1, and the outer contour of the decorative panel 10 matches the entrance of the accommodating cavity 3. The presence of this decorative panel perfectly conceals the entrance of the accommodating cavity when the housing is folded up, keeping the appearance of the housing intact and smooth, and combining aesthetics with a dustproof and moisture-proof sealing function.

[0027] In some specific embodiments, the accommodating cavity 3 has at least one top wall and two opposing side walls, and the lever handle mechanism 2 is hidden within the accommodating cavity 3 under the drive of the telescopic mechanism 4.

[0028] In some specific embodiments, the handle assembly 6 includes a handle base 13 and grip portions 14 symmetrically disposed at both ends of the handle base 13, the grip portions 14 being rotatably connected to the handle base 13 via a rotating shaft 17.

[0029] In some specific embodiments, a folding arm 15 is provided between the grip portion 14 and the handle base 13. The folding arm 15 is connected to the handle base 13 via a hinge 16. The hinge 16 is located outside the rotation shaft 17. The folding arm 15 can rotate around the hinge 16 to drive the grip portion 14 to fold or unfold.

[0030] In some specific embodiments, the pull rod assembly 5 includes an inner rod 18, an outer pull rod 19 sleeved outside the inner rod 18, and a base sleeve 20 sleeved outside the outer pull rod 19. The handle assembly 6 is fixed to the top of the outer pull rod 19. The inner rod 18 is connected to the handle assembly 6 via the folding arm 15. The base sleeve 20 is fixed to the front wheel assembly 7. The inner rod 18 is driven to move up and down via a drive assembly 21. The drive assembly 21 includes a motor and a lead screw 22 connected to the motor. The lead screw 22 is threadedly connected to the inner rod 18. In this embodiment, the motor is a servo motor, which has advantages such as high precision and fast response. This application adopts a nested sleeve structure (base sleeve 20, inner rod 18, outer pull rod 19), combined with the threaded connection between the lead screw 22 and the inner rod 18, integrating the driving, transmission, folding, and lifting functions into a coaxial layout, significantly reducing the structural space occupied, and is especially suitable for space-constrained scenarios such as electric suitcases. Furthermore, the complete cycle of "expanding + raising" and "retracting + lowering" can be achieved simply by rotating the drive unit in both directions, without the need for additional manual operation or multiple drive sources. This single-power-source-driven multi-action design simplifies the user's operation process and reduces the design complexity of the control system.

[0031] In some specific embodiments, the inner wall of the outer tie rod 19 is provided with an inwardly protruding limiting structure to restrict the rotation of the inner rod 18. By cooperating with the outer wall of the inner rod 18, the limiting structure can restrict the tendency of the inner rod 18 to rotate synchronously with the lead screw 22, ensuring that the rotational motion of the lead screw 22 is completely converted into the sliding motion of the inner rod 18 in the vertical direction.

[0032] When the inner rod 18 moves upward to its top and abuts against the handle seat 13, the folding arm 15 causes the grip part 14 to be in an unfolded state, and the inner rod 18 continues to move upward, causing the outer pull rod 19 to move upward in sync; when the inner rod 18 retracts downward to the point where the folding arm 15 abuts against the outer pull rod 19, the folding arm 15 causes the grip part 14 to be in a closed state.

[0033] When in riding mode, the handlebar assembly 6 and the lever assembly 5 need to be unfolded. At this time, the motor starts and its output shaft drives the lead screw 22 to rotate. Since the inner rod 18 is threadedly connected to the lead screw 22, the rotational motion of the lead screw 22 is converted into the upward sliding of the inner rod 18.

[0034] In the initial stage, when the inner rod 18 moves upward, the two sets of folding arms 15 pull the grips 14 on both sides respectively, so that the grips 14, which were originally in a folded state, rotate around the hinge point with the handle seat 13 and gradually change to an unfolded state.

[0035] When the grip part 14 is fully extended, the inner rod 18 continues to move upward. The top of the inner rod 18 contacts the handle seat 13, forcing the outer pull rod 19 to move upward synchronously. This causes the extended handle assembly 6 to rise together with the outer pull rod 19 until it reaches the preset working position, thereby raising the overall height of the handle assembly 6 and the pull rod assembly 5.

[0036] When the luggage needs to be switched from riding mode to non-riding mode, the drive assembly 21 drives the lead screw 22 to rotate in the opposite direction, and the inner rod 18 slides in the opposite direction (downward). The folding arm 15 pulls the grip 14 to rotate in the opposite direction, changing it from the unfolded state to the folded state, thus completing the handle folding process. Subsequently, the folding arm 15 on the inner rod 18 abuts against the outer pull rod 19, causing the outer pull rod 19 to move downward synchronously. Since the handle seat 13 is fixed to the top of the outer pull rod 19, the handle seat 13 and the folded grip 14 descend together with the outer pull rod 19 until they return to the initial working position.

[0037] In some specific embodiments, the telescopic mechanism 4 includes a telescopic rod 9, and the front wheel assembly 7 is fixed to one end of the telescopic rod 9 extending out of the housing 1. The telescopic rod 9 moves between a first extreme position and a second extreme position. When the telescopic rod 9 is in the first extreme position, the pull handle mechanism 2 and the front wheel assembly 7 extend out of the receiving cavity 3. When the telescopic rod 9 is in the second extreme position, the pull handle mechanism 2 and the front wheel assembly 7 retract into the receiving cavity 3, and the front wheel 8 is located below the housing 1. When the telescopic rod 9 moves to the first extreme position, the suitcase is in a riding state, and the pull handle mechanism 2 and the decorative panel 10 move out of the receiving cavity 3 along with the telescopic rod 9. When the telescopic rod 9 moves to the second extreme position, the electric suitcase is in a push-pull state, the pull handle mechanism 2 retracts backward into the receiving cavity 5, and the decorative panel 10 closes the receiving cavity 3. It is understandable that when the suitcase is in the push-pull state, the handle mechanism 2 is completely retracted into the accommodating cavity 3 of the suitcase body 10, and the entrance is tightly sealed by the decorative panel 10. This ensures that when the suitcase is used as a traditional suitcase, there are no protrusions or redundant structures on the outside, maintaining a smooth and complete integrated appearance that meets current aesthetic requirements. In the storage state, the accommodating cavity 3 provides a protected sealed space for the handle mechanism 2, which also avoids the risk of damage to the handle mechanism due to collisions or scratches during transportation or handling. At the same time, the ingenious structural design of this application allows the suitcase to maintain the neat shape of a standard suitcase when it needs to be checked in or stored, making it easier to put into a corner of a vehicle, aircraft cargo hold, or home, saving storage space.

[0038] In some specific embodiments, a protective shell 11 is also fitted around the outer periphery of the pull rod assembly 5. The pull rod assembly 5 is driven to rise and fall by a drive assembly 21, which is located inside the protective shell 11. The protective shell 11 is connected to the side of the decorative panel 10 facing the accommodating cavity 3. Encapsulating the drive assembly 21 within the protective shell 11 forms an independent sealed or semi-sealed space, which can effectively isolate dust and other foreign objects from entering, prevent external dirt from corroding the circuit, and extend the service life of the front upright mechanism. At the same time, the protective shell 11 acts as an outer cover for the pull rod handle mechanism, protecting and supporting its internal precision components. The height of the protective shell 11 is lower than the height of the decorative panel 10, and the shape of the protective shell 11 is adapted to the shape of the accommodating cavity 3. When the pull rod assembly 5 is retracted and the handle assembly 6 is folded, they are both hidden behind the decorative panel 10. When the electric suitcase is not in riding mode, the pull rod assembly 5 is retracted and the handle assembly 6 is folded back and extended by the telescopic mechanism 4 at the bottom, moving both the pull rod assembly 5 and the handle assembly 6 into the accommodating cavity 3. At the same time, the decorative panel 10 covers the accommodating cavity 3, making the appearance of the suitcase a complete and smooth plane, no different from ordinary suitcases, with both practicality and aesthetics.

[0039] In some specific embodiments, recesses 12 are provided on both sides of the upper end of the protective shell 11. The recesses 12 are used to accommodate the folded handle assembly 6. This provides a dedicated storage location for the folded handle, avoids interference with other components, and further reduces the space required for storage.

[0040] In some specific embodiments, after the pull handle mechanism 2 is concealed within the accommodating cavity 3 under the drive of the telescopic mechanism 4, the suitcase takes on a square shape. This makes the product indistinguishable from a regular suitcase when folded, facilitating stacking, storage, and transportation, and meeting users' dual needs for aesthetics and practicality.

[0041] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
