Description

Technical Field

[0001] This utility model relates to the technical field of luggage racks for rail transit, and in particular to a luggage rack structure with adjustable torque and opening angle. Background Technology

[0002] Most existing rail transit vehicles have wall-mounted, open-type luggage racks, whose main structure consists of end brackets, profile frames, and partitions. The profile frame typically has a curved aluminum plate in the middle to support the luggage. However, due to the open design of the luggage racks, there is a risk that items stored on them may fall and injure passengers due to severe vibrations of the vehicle, incorrect placement of the racks, or loose bag openings. Furthermore, passengers cannot easily see inside the overhead luggage racks when storing or retrieving their luggage, and collisions with other luggage during this process may cause items to fall. Additionally, the open luggage racks are often messy and unsightly, negatively impacting the passenger experience. Utility Model Content

[0003] The purpose of this utility model is to provide an adjustable torque and opening angle luggage rack structure to address the shortcomings of existing technologies, so as to facilitate passengers to quickly and safely store and retrieve their luggage while preventing luggage from falling off. The luggage racks are also uniform, simple and beautiful when opened.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: it includes a closed luggage rack body, an adjustable hinge, flap profiles, and a spring lock; the flap profiles are openably mounted on the closed luggage rack body via the adjustable hinges, and each flap profile is provided with a corresponding locking baffle. When the spring lock is pulled open, the locking tongue moves upward to outside the slot of the locking baffle to open the flap profile; the adjustable hinge has a torque to open the flap profile to its maximum angle, and the flap profiles automatically spring open when the spring lock is pulled open.

[0005] Furthermore, the adjustable hinge is provided with a torque adjusting bolt for adjusting the rotational torque.

[0006] Furthermore, the torque adjusting bolt adjusts the torque of the adjustable hinge by reducing friction during hinge rotation.

[0007] Furthermore, the adjustable hinge is also equipped with an angle adjustment bolt for adjusting the maximum opening angle.

[0008] Furthermore, the angle adjusting bolt limits the maximum opening angle of the flap profile by increasing the protruding portion of the bolt.

[0009] Furthermore, the bottom of the enclosed luggage rack body is provided with semi-transparent tempered glass.

[0010] Furthermore, the bottom of the enclosed luggage rack is also equipped with LED lights.

[0011] The luggage rack comprises an enclosed main body, adjustable hinges, flap profiles, and spring locks. The flap profiles are detachably mounted on the enclosed main body via the adjustable hinges. Each flap profile has a corresponding locking plate. When the spring lock is pulled open, the locking tongue moves upward beyond the slot of the locking plate to open the flap profile. The adjustable hinges have the torque to open the flap profiles to their maximum angle. When the spring lock is pulled open, the flap profiles automatically spring open. This design allows passengers to quickly and safely access their luggage while preventing luggage from falling out. The luggage racks also create a neat, uniform, and aesthetically pleasing appearance when all are opened. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] In the description of this utility model, it should be noted that the orientation or positional relationship indicated by terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.

[0023] An adjustable torque and opening angle luggage rack structure, such as Figures 1-6 As shown, the luggage rack includes a closed-type main body 1, an adjustable hinge 2, flap profiles 3, and a spring lock 4. The flap profiles 3 are movably mounted on the closed-type main body 1 via the adjustable hinge 2. Each flap profile 3 is provided with a corresponding locking baffle. When the spring lock 4 is pulled open, the locking tongue moves upward to the outside of the slot of the locking baffle to open the flap profile 3. The adjustable hinge 2 has a torque to open the flap profile 3 to the maximum angle. When the spring lock 4 is pulled open, the flap profile 3 automatically springs open.

[0024] Specifically, the closed luggage rack body 1 replaces the traditional open luggage rack. When storing luggage, it is completely enclosed inside the body, physically eliminating the risk of items falling and injuring passengers due to vehicle vibration, improper luggage placement, or loose bag openings. The adjustable hinge 2 provides a preset constant opening torque for the flap profile 3, ensuring that when the spring lock 4 is pulled open or unlocked, the flap profile 3 can automatically spring open to the preset maximum angle without requiring passengers to manually lift it. During the opening process and after reaching the maximum angle, the hinge torque can stably support the flap profile 3, preventing it from closing accidentally and avoiding pinching or colliding with luggage. The spring lock 4 has a simple design; passengers only need to pull the lock body outward. When pulled, the lock tongue moves upward and disengages from the slot on the corresponding lock baffle on the flap profile 3, thus unlocking the luggage. The unlocking action is intuitive and effortless, and the flap profile 3 automatically opens instantly upon unlocking, ensuring a seamless operation. The flap profile 3 automatically opens to its maximum angle, improving visibility and operational safety. Once unlocked, the flap profile 3 automatically opens and stabilizes at its maximum angle, fully opening the luggage rack entrance and providing passengers with a clear, unobstructed view, allowing them to easily observe the entire interior of the luggage rack and the arrangement of their luggage. In the closed state, the locking tongue of the spring lock 4 is firmly engaged in the slot of the flap profile 3 locking plate under the action of the spring force, forming a mechanical interlock. This reliably withstands vibrations and impacts during train operation, ensuring that the flap profile 3 remains tightly closed throughout the journey, safely sealing the luggage. Passengers no longer need to support the luggage with one hand and operate it with the other, as with traditional cover plates, greatly reducing the risk of luggage falling due to collisions caused by inconvenient operation.

[0025] As a preferred embodiment of the above, such as Figures 1-6 As shown, the adjustable hinge 2 is provided with a torque adjusting bolt 7 for adjusting the rotation torque.

[0026] As a preferred embodiment of the above, such as Figures 1-6 As shown, the torque adjusting bolt 7 adjusts the torque of the adjustable hinge 2 by reducing the friction during hinge rotation.

[0027] Specifically, the torque of the adjustable hinge 2 is adjusted by reducing friction during hinge rotation via the torque adjusting bolt 7. The reduction in friction corresponds more directly to the reduction in torque, resulting in high adjustment precision and more accurate, linear torque control. This avoids stress relaxation or fatigue issues caused by adjusting only the spring, ensuring the set torque is reliable and durable for more stable long-term performance. Reduced friction also makes the opening and closing of the flap profile 3 smoother and less jammed, resulting in a smoother operating feel. By reducing frictional loss, more torque is used to drive the cover movement, ensuring a fast and powerful opening and maximizing opening efficiency. Simultaneously, it avoids unstable opening speed or force due to friction fluctuations, improving action consistency. Furthermore, reduced friction means reduced wear, significantly improving the durability of the adjustable hinge 2. The torque adjusting bolt 7 reduces friction to a reasonable level, making it easier and less strenuous for passengers to manually close the flap profile 3. Even when the adjustable hinge 2 provides a large supporting torque, passengers can easily close the cover with less force.

[0028] As a preferred embodiment of the above, such as Figures 1-6 As shown, the adjustable hinge 2 is also provided with an angle adjusting bolt 8 for adjusting the maximum opening angle.

[0029] As a preferred embodiment of the above, such as Figures 1-6 As shown, the angle adjusting bolt 8 limits the maximum opening angle of the flap profile 3 by increasing the protruding part of the bolt.

[0030] Specifically, the maximum opening angle of the flap profile 3 is limited by increasing the protruding part of the bolt by the angle adjustment bolt 8. The angle adjustment bolt 8 is set on the adjustable hinge 2, which allows the amount of protrusion relative to the hinge body to be adjusted by rotating the bolt. When the flap profile 3 automatically opens under the torque drive of the adjustable hinge 2, its movement will eventually be physically blocked by a specific part of the protruding angle adjustment bolt 8, such as the bolt head or screw. By increasing the protruding part of the bolt, the maximum opening angle of the flap profile 3 can be reduced; conversely, reducing the protruding part (unscrewing the bolt) can increase the maximum opening angle, thus achieving fine and continuous adjustment of the maximum opening angle of the flap profile 3. The roof space of different vehicle models or installation locations, such as lights, air conditioning ducts, and roof curvature, may vary, which will limit the maximum opening angle of the luggage rack cover. The angle adjustment bolt 8 allows installers or maintenance personnel to quickly adjust the maximum opening angle on-site, perfectly avoiding obstacles above and preventing the flap profile 3 from hitting the roof equipment or structure during the pop-out process, ensuring equipment safety and avoiding abnormal noise. At the same time, the adjustable angle can ensure that the luggage rack opens uniformly, neatly and beautifully.

[0031] As a preferred embodiment of the above, such as Figures 1-6As shown, the bottom of the enclosed luggage rack body 1 is provided with semi-transparent tempered glass 5.

[0032] As a preferred embodiment of the above, such as Figures 1-6 As shown, the bottom of the enclosed luggage rack body 1 is also equipped with an LED light 6.

[0033] Specifically, the enclosed luggage rack body 1 features a semi-transparent tempered glass 5 at its bottom and an LED light 6 at its bottom. This semi-transparent tempered glass 5, positioned at the bottom of the enclosed luggage rack body 1 in the passenger's natural line of sight, allows passengers to clearly observe the general outline and location of items inside the rack without opening the flaps 3. This understanding of the internal layout before accessing items significantly reduces the risk of bumping into other luggage. The semi-transparency ensures visibility while avoiding the cluttered feeling that complete transparency might create, maintaining the aesthetics of the cabin. The LED light 6, located near the semi-transparent tempered glass 5, diffuses light evenly and softly through the glass, providing internal illumination. In dimly lit environments (such as at night or in tunnels), it illuminates the interior of the luggage rack, enhancing visibility through the glass 5 and ensuring passengers can clearly identify items. It also provides ambient lighting, offering comfortable indirect light to the area above passengers' heads, enhancing the cabin's nighttime atmosphere and sense of luxury. In addition to location guidance, the illuminated bottoms of the luggage racks become natural visual landmarks in the dark, making it easier for passengers to find their way.
