Description

TECHNICAL FIELD

[0002] In the existing rail train seats, the handrails are mainly divided into fixed type and reversible type. The fixed type handrails are commonly seen in high-speed rail first-class seats, while the reversible type handrails are commonly seen in second-class seats, and the upper half part of the reversible type handrails can be flipped to the direction of the backrest. However, both of the two types of handrail structures have a significant defect, that is, they cannot provide stable article placing space. If a passenger directly places a mobile phone or other small articles on the handrail, the articles are likely to slide off due to train vibration, and the natural placement of the arm is also affected, which reduces the riding comfort.

[0057] To enable those skilled in the art to better understand the technical solutions of this disclosure, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments.

[0058] Figure 1 The diagram schematically illustrates the structure of the armrest storage shelf in its unfolded state. Figure 2 This schematic diagram illustrates the structure of the armrest shelf of this disclosure in its folded state; Figure 3 A schematic diagram of the internal structure of the armrest shelf of this disclosure is shown. Figure 4 An exploded view of the armrest shelf of this disclosure is shown schematically.

[0059] This disclosure provides, in one aspect, an armrest storage rack 2, such as... Figures 1 to 4 As shown, it includes: a handrail body 1 and a shelf 2. The shelf 2 is rotatably mounted on the handrail body 1 via at least one pivot assembly 3, and has a horizontally extended state and a retracted state close to the handrail body 1.

[0060] Furthermore, the pivot assembly 3 includes a damping shaft, two connecting rods 31, an eccentric wheel 32, and an elastic unit 33. The two connecting rods 31 are respectively disposed on the armrest body 1 and the shelf 2, and the two connecting rods 31 are coaxially rotatably connected by the damping shaft; the eccentric wheel 32 is rotatably sleeved on the damping shaft and is configured to rotate with the shelf 2; the elastic unit 33 abuts against the circumference of the eccentric wheel 32; wherein, when the shelf 2 switches between the unfolded state and the retracted state, the degree of compression of the elastic unit 33 by the eccentric wheel 32 shows a trend of first increasing and then decreasing.

[0061] According to an embodiment of the present disclosure, the damping shaft is configured to keep the torsion value stable at 2 N when the two connecting rods 31 are relatively rotated.

[0062] According to the above setting mode, the rotation shaft assembly 3 realizes the convenient unfolding and automatic folding functions of the storage rack 2. The cooperation structure of the eccentric wheel 32 and the elastic unit 33 enables the storage rack 2 to be automatically positioned in the unfolded and folded states during the rotation process, and the stability can be maintained without an additional locking mechanism 5. At the same time, the coaxial rotation connection of the damping shaft and the connecting rod 31 ensures the smoothness and damping feeling of the operation process, which not only meets the convenience requirement of one-hand operation, but also avoids accidental folding caused by train vibration, effectively improving the convenience of placing small items and the riding comfort of passengers.

[0063] Specifically, the relative compression between the eccentric wheel 32 and the elastic unit 33 on the damping shaft improves the bearing capacity of the storage rack 2 in the unfolded state. The eccentric wheel 32 rotates synchronously with the storage rack 2, and the two are relatively fixed and stationary. The distance from the eccentric wheel 32 to the elastic unit 33 changes with the relative angle, and when it changes from the unfolded state to the folded state, the pressure curve of the elastic unit 33 is convex parabolic. The effect of this feature is that the force applied to the storage rack 2 needs to reach an upper limit before it can force the storage rack 2 to rotate, and the force increases synchronously with the increase of the rotation angle, so it can carry objects within a certain weight range.

[0064] In an illustrative embodiment, as shown in Figure 3 the positioning groove 21 is arranged in the storage rack 2; the first protrusion 321 of the eccentric wheel 32 is arranged at the first end of the eccentric wheel 32 and rotates synchronously with the eccentric wheel 32; and the first protrusion 321 and the positioning groove 21 are in clamping cooperation, so that the eccentric wheel 32 can rotate synchronously with the storage rack 2.

[0065] According to the above setting mode, the clamping cooperation between the positioning groove 21 in the storage rack 2 and the first protrusion 321 of the eccentric wheel 32 realizes the synchronous rotation of the eccentric wheel 32 and the storage rack 2, and ensures the coordination of the movement of the components of the rotation shaft assembly 3.

[0066] In detail, the first protrusion 321 of the eccentric wheel 32 is aligned with the positioning groove 21 in the storage rack 2 to form clamping cooperation; when the storage rack 2 is operated to rotate, the first protrusion 321 drives the eccentric wheel 32 to rotate synchronously, and the eccentric wheel 32 applies varying pressure to the elastic unit 33 through its eccentric structure, thereby realizing the smooth switching of the storage rack 2 between the unfolded and folded states. This process does not require additional operation steps, providing a convenient user experience.

[0067] In an illustrative embodiment, as shown in Figure 3As shown, the handrail body 1 is provided with a limiting gap 11; the second end of the eccentric wheel 32 is provided with a second protrusion 322, which rotates synchronously with the eccentric wheel 32; wherein the second protrusion 322 moves in the limiting gap 11, and abuts against one side wall of the limiting gap 11 when the storage rack 2 is in the unfolded state or the folded state.

[0068] According to the above setting mode, through the cooperation design of the limiting gap 11 of the handrail body 1 and the second protrusion 322 of the eccentric wheel 32, the accurate limiting of the unfolded and folded positions of the storage rack 2 is realized. The movement track of the second protrusion 322 in the limiting gap 11 ensures the controllability of the rotation angle of the storage rack 2, and the mechanical stop is formed when it abuts against the side wall of the limiting gap 11, which not only ensures the horizontal stability in the unfolded state, but also ensures the compact fit in the folded state, and at the same time enhances the reliability and service life of the overall structure.

[0069] In detail, the second protrusion 322 of the eccentric wheel 32 rotates in the limiting gap 11 to make a circular motion with the storage rack 2, and when the storage rack 2 rotates to the unfolded or folded position, the second protrusion 322 contacts the corresponding side wall of the limiting gap 11 to form mechanical limiting. This limiting structure can automatically realize position locking without additional operation, and cooperates with the mechanical properties of the eccentric wheel 32 and the elastic unit 33, so that the storage rack 2 can be stably kept in the required working state.

[0070] In an illustrative embodiment, as shown in Figure 4 The end of the connecting rod 31 away from the damping shaft is provided with a connecting plate 34, and the connecting plate 34 is connected with the storage rack 2 or the handrail body 1 through fasteners.

[0071] According to the embodiment of the present disclosure, one of the two connecting rods 31 is fixedly connected with the groove bottom surface of the positioning groove 21, and the other connecting rod 31 is directly fixedly connected with the handrail body 1, so that when relative rotation occurs, the damping between the damping shafts generates a rotating resistance between the handrail body 1 and the storage rack 2, and good hand feeling and quality feeling are provided.

[0072] In an illustrative embodiment, as shown in Figure 2 The storage rack 2 is provided with a limiting protrusion 22, and the limiting protrusion 22 abuts against the handrail body 1 when the storage rack 2 is in the folded state.

[0073] In detail, the limiting protrusion 22 is arranged at the bottom of the storage rack 2, and when the storage rack 2 is rotated downward and moves close to the handrail body 1, the limiting protrusion 22 abuts against the handrail body 1 to limit the storage rack 2 in the folded state, so as to avoid excessive rotation to cause structural damage.

[0074] In an illustrative embodiment, as shown in Figure 4As shown, the handrail body 1 is provided with a support table 12 for mounting the elastic unit 33; the elastic unit 33 includes an elastic pad 332 and a plastic pad 331, the elastic pad 332 is arranged on the support table 12; the plastic pad 331 is arranged on the elastic pad 332 and abuts between the elastic pad 332 and the eccentric wheel 32.

[0075] According to the above setting mode, a stable and reliable elastic support system is constructed through the combined design of the support table 12, the elastic pad 332 and the plastic pad 331. The elastic pad 332 provides the necessary elastic restoring force, while the plastic pad 331 plays a buffering and force transmission role, and the two work together to ensure that the eccentric wheel 32 can obtain a smooth damping effect when rotating. The plastic pad 331 is used as an intermediate part between the eccentric wheel 32 and the elastic pad 332, the friction between the plastic pad 331 and the eccentric wheel 32 is small, and the plastic pad 331 can evenly press the elastic pad 332 with the pressure generated by the eccentric wheel 32 on the contact surface between them. This layered elastic unit 33 structure not only improves the force transmission efficiency, but also prolongs the service life.

[0076] In detail, when the eccentric wheel 32 rotates, the pressure is evenly transmitted to the elastic pad 332 through the plastic pad 331, and the elastic pad 332 generates corresponding deformation and provides restoring force. This structure realizes smooth transmission and effective buffering of force, ensuring the smoothness of the rotating process of the shelf 2 and the accuracy of positioning.

[0077] In an exemplary embodiment, as shown in Figure 4 The bottom of the plastic pad 331 is provided with a protruding positioning convex 3311; the top of the elastic pad 332 is provided with a positioning groove 3321 matched with the positioning convex 3311, and the positioning convex 3311 and the positioning groove 3321 form a plug-in fit.

[0078] Specifically, through the plug-in fit design of the positioning convex 3311 at the bottom of the plastic pad 331 and the positioning groove 3321 at the top of the elastic pad 332, precise positioning and reliable connection between the two pads are realized. This mechanical interlocking structure not only ensures the positioning accuracy between the components of the elastic unit 33, but also effectively prevents the relative sliding between the pads when the eccentric wheel 32 rotates and exerts force, so that the pressure is evenly transmitted to the entire elastic unit 33, ensuring the stability of the rotating process of the shelf 2 and the positioning accuracy.

[0079] In an exemplary embodiment, the plastic pad 331 and the elastic pad 332 are made into an integrated structure by using an insert injection molding process. The side wall of the eccentric wheel 32 is provided with a protruding block in the tangent direction. When the eccentric wheel 32 is deflected to be in contact with the elastic unit 33, the top surface of the protruding block is in full contact with the elastic unit 33, thereby significantly increasing the contact area. This integrated design not only simplifies the assembly process, but also improves the structural strength and durability of the assembly, and ensures that the force transmission is more uniform and stable.

[0080] In an alternative exemplary embodiment, the elastic unit 33 is designed in a full-flexible structure, and the original plastic pad 331 is cancelled. The top of the elastic unit 33 is provided with a special wedge tooth structure. When the protruding block of the eccentric wheel 32 is in contact with the wedge tooth, the reverse rotation of the shelf 2 can be effectively limited. Only when the operator actively applies pressure to deform the wedge tooth, the restriction state can be released, and the reverse rotation of the shelf 2 can be realized. This design not only ensures the safety during use, but also maintains the convenience of operation, and further simplifies the overall structure.

[0081] Figure 5 An exemplary top view of the internal structure of the handrail shelf 2 of the present disclosure is shown.

[0082] In an exemplary embodiment, as shown in Figure 5 , the shelf 2 and the handrail body 1 are connected by two coaxially arranged shaft assemblies 3, and the two shaft assemblies 3 are symmetrically arranged on the two sides of the shelf 2 in the width direction.

[0083] According to the above arrangement, the structural stability and carrying capacity of the shelf 2 are significantly improved by the symmetrical arrangement of the double shaft assemblies 3. The coaxial arrangement of the double shafts ensures the synchronization and balance during rotation, effectively preventing the deflection or jamming phenomenon caused by single-sided stress.

[0084] According to the embodiments of the present disclosure, the damping shaft includes but is not limited to a character-shaped damping shaft.

[0085] Figure 6 An exemplary sectional view of the eccentric wheel 32 of the handrail shelf 2 of the present disclosure is shown.

[0086] In an exemplary embodiment, as shown in Figure 6 , the eccentric wheel 32 is a cylindrical structure, and the eccentric hole 323 is arranged in the center of the eccentric wheel 32. The axis of the eccentric hole 323 is offset from the axis of the eccentric wheel 32. When the shelf 2 is in the unfolded state, the major axis of the eccentric wheel 32 forms a 15° angle with the vertical direction.

[0087] According to the above setting mode, the eccentric hole 323 and the eccentric shaft of the eccentric wheel 32 are offset, which produces asymmetric mechanical properties. When the shelf 2 is in the unfolded state, the 15° angle design makes the elastic unit 33 produce the best righting moment, which not only ensures the horizontal stability of the unfolded state, but also provides a moderate operating moment, so that the shelf 2 can be stably kept in the working position and is not easy to be accidentally folded. This precise geometric parameter design not only ensures the functionality, but also optimizes the user's operation experience.

[0088] According to an embodiment of the present disclosure, the eccentric wheel 32 can be processed based on a round roller. The side walls of the round roller are cut so that the distances from the center of each side wall are not equal.

[0089] In an illustrative embodiment, as shown in Figure 4 The shelf 2 is internally integrated with a wireless charging module 4.

[0090] In detail, the wireless charging module 4 provides wireless charging function and provides charging function for mobile phones, smart watches or other terminal devices supporting wireless charging.

[0091] In an illustrative embodiment, as shown in Figure 6 The shelf 2 further includes a locking mechanism 5 for locking the shelf 2 during the wireless charging process of the wireless charging module 4. The locking mechanism 5 includes a positioning block 51, a positioning column 52, a limiting swing lever 53, a lock catch 54 and an electromagnetic attractor 55.

[0092] Specifically, the positioning block 51 is arranged on the side wall of the eccentric wheel 32, the positioning column 52 is arranged on the positioning block 51 and extends along the axis of the eccentric wheel 32, the limiting swing lever 53 is rotatably arranged in the shelf 2, and the positioning column 52 cooperates with the limiting swing lever 53 rotatably connected to the shelf 2. The limiting swing lever 53 has a limiting slot 531 with a limiting opening 532. The rotation shaft of the limiting swing lever 53 is parallel to the rotation shaft of the eccentric wheel 32. During the unfolding process of the shelf 2, the eccentric wheel 32 drives the positioning column 52 to enter the limiting slot 531 from the limiting opening 532.

[0093] Further, the lock catch 54 is elastically connected to the shelf 2 by a resilient member, and the rotation shaft of the lock catch 54 is arranged orthogonally to the rotation shaft of the limiting swing lever 53. The electromagnetic attractor 55 is electrically connected to the wireless charging module 4 to ensure the synchronization of the working state. When the wireless charging module 4 detects a charging device, the electromagnetic attractor 55 immediately attracts the lock catch 54, so that the lock catch 54 is in the rotation path of the limiting swing lever 53 and limits the further rotation of the limiting swing lever 53, and the automatic locking of the shelf 2 is realized by the mechanical cooperation of the positioning column 52 and the limiting slot 531.

[0094] The limiting opening 532 of the limiting slot 531 of the locking mechanism 5 is designed to allow the positioning column 52 to enter in one direction only, ensuring the reliability of the locking process. The entire system realizes the intelligent linkage of the wireless charging state and the locking state of the shelf 2, ensuring the safety of the device during charging and providing a convenient user experience.

[0095] According to an embodiment of the present disclosure, the locking buckle 54 and the limiting swing rod 53 are arranged with orthogonal rotating shafts, maximizing the space utilization while ensuring the accuracy of the mechanism action. The limiting opening 532 of the limiting slot 531 is designed with a special profile, allowing the positioning column 52 to enter smoothly but not to come out accidentally. The control circuit of the electromagnetic attractor 55 is deeply integrated with the wireless charging module 4, achieving a response speed of milliseconds.

[0096] Specifically, when the electromagnetic attractor 55 is working, the locking buckle 54 will rotate against the elastic force of the elastic member away from the electromagnetic attractor 55 and be tightly attracted to the attractor; when the charging is stopped, the locking buckle 54 is automatically reset under the action of the elastic member, releasing the restriction on the limiting swing rod 53. This intelligent design ensures that the shelf 2 remains stable during charging, effectively preventing valuable devices from being damaged by accidental impact.

[0097] According to an embodiment of the present disclosure, when the user unfolds the shelf 2 and places a terminal device supporting wireless charging, the system automatically enters the locked state; when the device is removed, the lock is automatically released, allowing the shelf 2 to be freely folded. This design not only solves the safety hazards of traditional shelves 2 during charging, but also greatly improves the reliability and service life of the product through mechatronic design.

[0098] Another aspect of the present disclosure provides a rail train comprising a car body handrail shelf 2, which is arranged on the side wall or seat of the car body.
