Description

Technical Field

[0001] This invention relates to the field of aircraft design, specifically to the field of aircraft baggage compartment structure design, and particularly to a baggage tray for an aircraft cabin baggage compartment and an aircraft cabin baggage compartment. Background Technology

[0002] Aircraft baggage compartments are an important part of modern civil aircraft, mainly used to store passengers' baggage and cargo.

[0003] With the rapid development of the air travel industry, passengers have increasingly higher demands for the flight experience, especially for the convenience of baggage storage and the efficiency of space utilization.

[0004] The floor of existing aircraft baggage compartments is typically flat, resulting in direct contact and friction between luggage and the compartment floor. Passengers need to exert considerable force to drag luggage, especially heavy items, within the compartment when retrieving or placing them, leading to a poor user experience and potentially causing excessive time spent on baggage retrieval and aisle congestion. The high position of the baggage compartment further exacerbates the difficulty of handling luggage due to the friction between the luggage and the floor. Furthermore, this issue not only increases the difficulty of operation for passengers but also causes severe wear and tear on the compartment floor, shortening its lifespan.

[0005] Existing luggage compartments are single, fixed spaces, which cannot meet the diverse needs of passengers for luggage placement, such as luggage that cannot be compressed or requires separate small spaces. A common problem is that when multiple layers of luggage are stacked in the compartment, the luggage on top easily slips off.

[0006] The current problem is that, especially when the baggage compartment lids are closed, passengers and crew cannot directly see the remaining space in each baggage compartment. Summary of the Invention

[0007] In view of the above-mentioned deficiencies of the prior art, the present invention aims to provide a baggage tray for use in the baggage compartment of an aircraft cabin. include: The first board assembly includes: A substrate, the substrate defining a working surface facing the luggage to be placed; and A protruding member, the protruding member extending beyond the working surface of the substrate by a certain height; The second board assembly includes: A slotted plate, the slotted plate defining a support surface facing the luggage to be placed and a switching surface opposite to the support surface and opposite to the base plate, and the slotted plate having a slot through the thickness of the plate, and the second plate assembly being positioned such that the slot is substantially aligned with the protrusion. A tray shape switching mechanism is configured to allow the relative positioning of the substrate and the slotted plate to switch between an undulating state and a flat state. In the undulating state, the convex member extends a first volume through the slot from the support surface of the slotted plate. In the flat state, the convex member either does not extend through the slot from the support surface of the slotted plate or extends through the slot from the support surface of the slotted plate by a second volume smaller than the first volume. An elastic recovery mechanism provides an elastic force configured to cause the substrate and the slotted plate to move relative to each other toward the undulating state.

[0008] According to a preferred, but not limiting, embodiment of the baggage tray for an aircraft cabin baggage compartment of the present invention, the protruding member includes at least a portion of a spherical member protruding from the working surface of the substrate.

[0009] According to a preferred, but not limiting, embodiment of the baggage tray for an aircraft cabin baggage compartment of the present invention, the working surface of the substrate is provided with a receiving slot, and the protruding member includes a ball that can be rolled and received in the receiving slot. The slots in the perforated plate are circular; and In the flat state, the spherical surface of the convex member is substantially tangent to the supporting surface of the slotted plate.

[0010] According to a preferred, but not limiting, embodiment of the baggage tray for an aircraft cabin baggage compartment of the present invention, an anti-slip pad is provided on the support surface of the perforated plate so that, in the flat state, baggage placed on the support surface can contact the anti-slip pad.

[0011] According to a preferred, but not limiting, embodiment of the baggage tray for an aircraft cabin baggage compartment of the present invention, the tray shape switching mechanism includes an abutment sliding surface on one of the working surface of the base plate and the switching surface of the slotted plate, extending from a distant end toward the other end along a switching direction, and an abutment member fixedly extending from the other of the working surface and the switching surface to engage with the abutment sliding surface, such that when the abutment member engages with the distant end of the abutment sliding surface, the baggage tray is in the flat state, and when the abutment member engages with the near end of the abutment sliding surface, the baggage tray is in the undulating state.

[0012] According to a preferred, but not limiting, embodiment of the baggage tray for an aircraft cabin baggage compartment of the present invention, a slot extending along the switching direction is provided on the base plate, and the abutment sliding surface is arranged on a slider that can be engaged in the slot and can slide relative to the base plate between a remote position and a near position along the switching direction. When the slider is in the remote position, the abutment engages with the remote end of the abutment sliding surface, and when the slider is in the near position, the abutment engages with the near end of the abutment sliding surface.

[0013] According to a preferred, and not limiting, embodiment of the baggage tray for an aircraft cabin baggage compartment of the present invention, the elastic return mechanism includes a first elastic member disposed between the slider and the base plate, the first elastic member providing the slider with an elastic force relative to the base plate toward the approach position.

[0014] According to a preferred, but not limiting, embodiment of the baggage tray for an aircraft cabin baggage compartment of the present invention, the elastic recovery mechanism includes a second elastic member disposed between the base plate and the slotted plate, the second elastic member providing a second elastic force to the slotted plate relative to the base plate toward the undulating state.

[0015] The present invention also provides an aircraft cabin baggage compartment, including a baggage tray according to any of the foregoing embodiments, wherein the tray configuration switching mechanism includes a baggage compartment cover, and the tray configuration switching mechanism is configured such that when the baggage compartment cover is closed in place, the baggage tray is switched to the flat state.

[0016] According to a preferred, but not limiting, embodiment of the aircraft cabin baggage compartment of the present invention, the base plate of the baggage tray is fixedly installed at the bottom of the aircraft cabin baggage compartment, and the aircraft cabin baggage compartment further includes: A movable baggage tray is arranged on a scissor-mounted telescopic frame. The scissor-mounted telescopic frame is suspended from the top of the baggage compartment of the aircraft cabin and can drive the movable baggage tray to move vertically. The movable baggage tray includes multiple sub-movable baggage trays that can be stacked vertically and unfolded in a direction perpendicular to the vertical direction. The bottom end of the telescopic frame is fixed with a locking and limiting device that cooperates with the limiting recess in the movable baggage tray. The locking and limiting device includes a limiting pin, a locking knob, and a limiting elastic element. The limiting pin can extend into the limiting recess along the limiting direction under the action of the limiting elastic element, and can move away from the limiting recess in the opposite direction of the limiting direction against the action of the limiting elastic element. The locking knob cooperates with the limiting pin and can rotate between a locked position and an unlocked position. In the locked position, the limiting pin is restricted from moving away from the limiting recess. In the unlocked position, the limiting pin can move freely relative to the movable baggage tray. And / or The luggage compartment occupancy detection device includes multiple bottom sensors distributed on the luggage tray, multiple high sensors distributed on the side walls of the luggage compartment, and an occupancy indicator. The bottom sensors are configured to detect luggage occupancy in the vertical upward direction at their location, and the high sensors are configured to detect luggage occupancy in the horizontal direction towards the opposite side wall at their location. The occupancy indicator displays the corresponding luggage occupancy status based on the sensing data from the bottom sensors and / or the high sensors. The occupancy indicator is located in a position that can be observed even when the luggage compartment lid is fully closed.

[0017] The advantages of the luggage tray and luggage compartment according to the preferred embodiment of the present invention are at least as follows: 1) By installing protruding parts such as multiple sets of universal rollers on a fixed first plate assembly, the present invention makes it more convenient to pick up, put down and move luggage, which not only improves the convenience of luggage picking up and putting down, but also reduces the wear and tear between luggage and the bottom wall of the cabin.

[0018] 2) By incorporating features such as movable perforated plates, and elastic return mechanisms implemented through mechanisms like spring-loaded return elements and supports, the perforated plates can automatically rise or fall according to the opening and closing of the hatch. Because the movement of the perforated plates is linked to the hatch, no additional operation is required, significantly improving ease of use. After luggage is placed, closing the hatch triggers the supports to lift the perforated plates upwards. At this point, the upper surface of the perforated plates is flush with the top of the casters, creating friction between the luggage and the perforated plates, preventing relative slippage and ensuring the luggage remains stable within the hatch. When luggage needs to be retrieved, opening the hatch removes the support force on the perforated plates, allowing them to descend under their own weight. Simultaneously, the elastic return mechanism ensures the perforated plates remain in a low position, with the top of the casters higher than the perforated plates, facilitating easy access to luggage.

[0019] 3) This invention, by configuring a baggage compartment occupancy detection device, allows passengers and staff to visually understand the placement of baggage inside the compartment from the outer wall of the compartment, without having to open each compartment cover to check for available space. This significantly improves baggage storage efficiency and space utilization.

[0020] 4) This invention incorporates movable luggage trays, including, for example, a main partition and a secondary partition. In its initial state, the main partition is folded and stored at the top of the cabin, without affecting the normal storage of luggage. Only when there is remaining space in the upper level can the main partition be unfolded downwards, thereby dividing the cabin into layers. This effectively prevents luggage from sliding due to stacking, ensuring stable storage and avoiding space waste caused by lower-level luggage being less resistant to pressure, thus optimizing space utilization efficiency and storage safety. Furthermore, the pull-down height of the main partition can be precisely adjusted using a scissor-type telescopic rack to better suit the actual height requirements of the stored luggage. The secondary partition can be flexibly unfolded depending on the size of the luggage, further optimizing space division and making the entire cabin more efficient in its use.

[0091] Embodiments of the invention will now be described in detail, examples of which are shown in the accompanying drawings and described below.

[0092] Although the invention will be described in conjunction with exemplary embodiments, it should be understood that this specification is not intended to limit the invention to the embodiments illustrated. Rather, the invention is intended to cover not only these exemplary embodiments, but also various alternatives, modifications, equivalents, and other embodiments that may be included within the spirit and scope of the invention.

[0093] To facilitate explanation and precise definition of the technical solutions of the present invention, the terms "upper," "lower," "inner," and "outer" are used to describe these features with reference to the positions of features in the exemplary embodiments shown in the accompanying drawings.

[0094] The present invention provides a multi-functional layered aircraft baggage compartment that facilitates baggage retrieval and loading, including a compartment body 1 and a baggage compartment cover 2.

[0095] The inner top wall of the cabin 1 is provided with an installation groove 11, the luggage compartment cover 2 is hinged to the upper front end of the cabin 1, and two or more sets of base plates 3 are fixedly connected to the inner bottom of the cabin 1.

[0096] The base plate 3 can be fixed. Multiple sets of universal rollers 4 are detachably connected to the upper working surface of the base plate 3, and a slotted plate 5 is slidably connected above the base plate 3. The slotted plate 5 can be movable. The universal rollers 4 are only a preferred embodiment shown in the accompanying drawings. According to the concept of the present invention, the fixed base plate 3 can be provided with any protruding member extending from the working surface of the base plate 3, including but not limited to a rounded conical end, at least a portion of a spherical member, etc.

[0097] The slotted plate 5 has multiple sets of slots 51 that cooperate with the universal rollers 4 on the upper support surface. Multiple sets of elastic return mechanisms 6 are provided on the left and right sides of the slotted plate 5 to make the slotted plate 5 move down through elasticity. Their function is to press the slotted plate 5 down through elastic force.

[0098] The working surface of the substrate 3, located below the slotted plate 5, is also connected to multiple sets of support members 6 that can drive the slotted plate 5 to rise relative to the substrate 3.

[0099] When the luggage compartment cover 2 is closed, it triggers the support member 6 to lift the slotted plate 5, making the supporting surface of the slotted plate 5 level with the highest point of the universal roller 4; when the luggage compartment cover 2 is opened, it triggers the elastic return mechanism 6 to press the slotted plate 5 down, making the supporting surface of the slotted plate 5 lower than the highest point of the universal roller 4. In this text, the state where the supporting surface of the slotted plate 5 is level with the highest point of the universal roller 4 is referred to as the flat state of the luggage tray, while the state where the supporting surface of the slotted plate 5 is lower than the highest point of the universal roller 4 is referred to as the undulating state of the luggage tray. It is easy to understand that the luggage compartment cover 2 at this time can be regarded as part of a tray shape switching structure for switching the shape of the luggage tray. Figure 6 and Figure 7 As clearly shown, the tray shape switching mechanism is configured to allow the relative positioning of the substrate 3 and the slotted plate 5 to switch between an undulating state and a flat state. In the undulating state, the convex member extends through the slot from the supporting surface of the slotted plate 5 into a first volume ( Figure 7 In a flat state, the convex member does not extend beyond the support surface of the slotted plate 5 through the slot; for example, the surface of the convex member is tangent to the support surface of the slotted plate 5. Figure 6 ) or through the slot, extending from the supporting surface of the slotted plate 5 into a second volume smaller than the first volume ( Figure 6 and Figure 7 (The state between).

[0100] By installing multiple sets of omnidirectional casters 4 on the base plate 3, the loading, unloading, and movement of luggage becomes more convenient. The omnidirectional casters 4 can rotate flexibly at multiple angles. When luggage needs to be placed, simply push the luggage inwards towards the compartment 1, and the luggage will cause the omnidirectional casters 4 to roll inwards. When luggage needs to be removed, simply pull the luggage outwards towards the compartment 1, and the luggage will cause the omnidirectional casters 4 to roll outwards. Furthermore, when the position of luggage within the compartment 1 needs to be adjusted, the luggage can cause the omnidirectional casters 4 to roll left or right. The omnidirectional casters 4 not only improve the convenience of loading and unloading luggage but also reduce wear and tear between the luggage and the inner wall of the compartment 1.

[0101] By incorporating a slotted plate 5, a flexible return mechanism 6, and a support member 6, the slotted plate 5 can automatically rise or fall according to the opening and closing of the luggage compartment lid 2. Since there is a linkage mechanism between the movement of the slotted plate 5 and the luggage compartment lid 2, no additional operation is required, significantly improving ease of use. After luggage is placed, closing the luggage compartment lid 2 triggers the support member 6 to lift the slotted plate 5 upwards. At this time, the supporting surface of the slotted plate 5 is flush with the top of the universal rollers 4, causing friction between the luggage and the slotted plate 5, thus preventing relative slippage between the luggage and the universal rollers 4 and ensuring the luggage remains stable and does not shift within the compartment. When luggage needs to be retrieved, opening the luggage compartment lid 2 removes the supporting force of the support member 6 on the slotted plate 5, and the slotted plate 5 will descend under its own weight. Simultaneously, the flexible return mechanism 6 ensures that the slotted plate 5 remains in a low position, so that the top of the universal rollers 4 is higher than the slotted plate 5, making it easy to retrieve luggage. In other words, the elastic force provided by the elastic recovery mechanism of the present invention causes the substrate and the slotted plate to move relative to each other in an undulating state.

[0102] Preferably, the universal roller 4 may include a base sleeve 41 and a universal ball 42. The base sleeve 41 is threadedly and detachably connected to the base plate 3. The universal ball 42 is rotatably connected inside the base sleeve 41. That is, the universal ball 42, acting as a ball bearing, can be rolled and accommodated in a receiving slot. The base sleeve 41 has a detachable structure, so that when a single universal roller 4 fails, it can be easily removed and replaced.

[0103] Side seats 32 are fixedly connected to both the left and right sides of the substrate 3, and guide grooves 321 are formed on the upper surface of the side seats 32. A fixing plate 322 is detachably connected to the upper opening of the guide groove 321 by bolts.

[0104] The elastic return mechanism 6 includes an L-shaped guide plate 53 and a second elastic element 54. The second elastic element 54 can be a spring. The L-shaped guide plate 53 is fixedly connected to one side of the slotted plate 5. The second elastic element 54 is fixedly connected to the upper end of the L-shaped guide plate 53, and the upper end of the second elastic element 54 abuts against the lower part of the fixed plate 322. Under the elastic action of the second elastic element 54, the slotted plate 5 moves downward, so that the supporting surface of the slotted plate 5 is lower than the highest point of the universal roller 4. The fixed plate 322 adopts a detachable structure, which facilitates the subsequent replacement of the spring in the guide groove 321. When the luggage compartment cover 2 is opened, the slotted plate 5 slides down by its own weight. At the same time, the second elastic element 54 restores its deformation and presses the L-shaped guide plate 53 downward, thus elastically pressing the slotted plate 5 downward through its elastic properties. When the luggage compartment cover 2 is closed, the trigger support 6 lifts the slotted plate 5. At this time, the second elastic element 54 is in a compressed state, thereby ensuring that when the luggage compartment cover 2 is subsequently opened, the slotted plate 5 can quickly descend under the elastic potential energy of the second elastic element 54. The above-mentioned arrangement of the second elastic element 54 is a preferred arrangement of the second elastic element. Those skilled in the art can also arrange other forms of the second elastic element 54 in other corresponding positions, as long as it can provide an elastic force between the substrate 3 and the slotted plate 5 to make both move in an undulating state, for example, it can be arranged between the working surface of the substrate 3 and the switching surface of the slotted plate 5, etc.

[0105] Preferably, multiple sets of anti-slip pads 52 can be adhered to the support surface of the slotted plate 5 to prevent items from sliding. The multiple sets of anti-slip pads 52 facilitate subsequent replacement of any worn anti-slip pads 52. Furthermore, when the support member 6 presses upwards against the slotted plate 5, the anti-slip pads 52 on the support surface of the slotted plate 5 will contact the bottom of the luggage and gradually compress. In other words, in the flat state of the luggage tray, luggage placed on the support surface of the slotted plate can contact the anti-slip pads 52. Moreover, the multiple sets of anti-slip pads 52 can automatically adjust the degree of compression according to the pressure exerted upon contact with the luggage, thereby optimizing the anti-slip effect between the slotted plate 5 and the luggage.

[0106] Preferably, multiple sets of slots 31 are formed through the surface of the substrate 3. The slots can be slots with one open end. The front side of the slot 31 is open, and multiple sets of abutment members 55 are fixedly connected to the switching surface of the slot plate 5. The abutment member 55 can be, for example, a fixed hemisphere. The support member 6 includes a fixed frame 61, a slider 62, and multiple sets of abutment sliding blocks 63 with inclined upper surfaces. The fixed frame 61 is slidably connected inside the slot 31, and the slider 62 is slidably connected inside the fixed frame 61. The multiple sets of abutment sliding blocks 63 are equidistantly fixed on the upper surface of the slider 62, and each abutment sliding block 63 corresponds to one abutment member 55. Pushing the slider 62 backward causes the abutment sliding block 63 to abut and lift the abutment member 55. The slider 62 can be plate-shaped. The abutment sliding block 63 can be triangular. The front opening design of the slot 31 facilitates the removal of the fixed frame 61. When a single support member 6 loses its supporting function, the fixed frame 61 can be directly removed from the slot 31. The raising and lowering of the slotted plate 5 relies on the coordinated action of the abutting slider 63 and the abutting member 55. As the slider 62 moves backward, the abutting slider 63 gradually lifts the abutting member 55, thereby indirectly raising the position of the slotted plate 5. The abutting member 55 ensures that excessive friction is not generated when it contacts the abutting slider 63. It should be noted that the aforementioned fixing frame 61 can be regarded as part of the slot. The aforementioned abutting member 55 is not necessarily a fixed hemisphere; as long as it can contact the abutting sliding surface to drive the movement of the slotted plate 5, it can be, including but not limited to, wedge-shaped members, columnar members, etc. Furthermore, the aforementioned abutting slider 63 can be roughly triangular in shape as shown in the figure, but it can also be in the form of other protrusions that gradually approach each other along the switching direction from the far end to the near end.

[0107] Preferably, a circular hole 612 is provided through the front side of the fixed frame 61, and a movable column 64 is fixedly connected to the front side of the slider 62. The movable column 64 is slidably connected inside the circular hole 612 and extends to the front side of the fixed frame 61. A first elastic member 65 is sleeved on the outer side of the movable rod 66. The front end of the first elastic member 65 is fixedly connected to the inner front side wall of the fixed frame 61, and the rear end of the first elastic member 65 is fixedly connected to the front side wall of the slider 62. Under the elastic action of the first elastic member 65, the slider 62 is located at the front side of the fixed frame 61, so that the abutting sliding block 63 is located at the lower front side of the corresponding abutting member 55 and the two are out of contact. The front ends of multiple sets of movable columns 64 are detachably connected to the movable rod 66. When the luggage compartment cover 2 is fastened, it pushes the movable rod 66 to move backward, so that the abutting sliding block 63 moves backward and lifts the corresponding abutting member 55. In this design, the first elastic element 65 initially pulls the slider 62 to the front position inside the fixed frame 61, leaving a certain clearance between the movable rod 66 and the fixed frame 61. The first elastic element 65 can be a spring. The movement of the slider 62 depends on the movable column 64 and the movable rod 66 connected to its front end. When the luggage compartment cover 2 is closed, it pushes the movable rod 66 backward, and the movable rod 66 drives the slider 62 to slide backward through multiple sets of movable columns 64. At this time, the abutting sliding block 63 interacts with the abutting member 55, pushing the slotted plate 5 upward. During this process, the first elastic element 65 is stretched. When the luggage compartment cover 2 is opened, the movable rod 66 loses its abutting force, and the first elastic element 65 quickly recovers its deformation, thereby resetting the slider 62 to the front position inside the fixed frame 61. At this time, the abutting sliding block 63 is away from directly below the abutting member 55, and the slotted plate 5 loses the lifting support force of the support member 6. The arrangement of the first elastic element 65 described above is a preferred arrangement of the first elastic element. Those skilled in the art can also arrange other forms of the first elastic element at other corresponding positions, as long as it can provide an elastic force between the slider and the substrate that causes the slider to move relative to the substrate towards a closer position. For example, it can be arranged between the inner side of the end of the slider extending from the edge of the substrate and the edge of the substrate, etc. In this document, the first elastic element 65 is also considered as an optional embodiment of the elastic recovery mechanism 6, because the first elastic element 65 essentially still realizes the downward pressure of the slotted plate 5 under elastic action.

[0108] It should be noted that the thrust applied to the luggage compartment cover 2 is sufficient to lift the perforated plate 5. This is because when luggage is placed inside the compartment 1, most of the weight is distributed through the casters 4, at which point the support 6 lifts the perforated plate 5, and the luggage does not exert additional pressure on the perforated plate 5.

[0109] Preferably, an inner slide rail 611 is fixedly connected to the inner bottom of the fixed frame 61, and a long slide bar 621 is fixedly connected to the lower surface of the slider 62. The long slide bar 621 is slidably connected inside the inner slide rail 611. The slider 62 drives the long slide bar 621 to slide inside the inner slide rail 611, providing positioning and guidance for the slider 62.

[0110] Please see Figures 1-5 In this embodiment, as another implementation of the present invention, a luggage compartment occupancy detection device (also called) 7 is installed on the inner and outer walls of the cabin 1 to intuitively determine the remaining space inside the cabin 1.

[0111] This invention, by configuring a baggage compartment occupancy detection device 7, allows passengers and staff to visually understand the placement of baggage inside the compartment from the outer wall of the compartment 1, without having to open each baggage compartment cover 2 to check for available space. This significantly improves baggage storage efficiency and space utilization.

[0112] Preferably, the luggage compartment occupancy detection device 7 includes multiple sets of bottom position sensors 71 and multiple sets of high position sensors 72. The multiple sets of bottom position sensors 71 are fixedly connected to the working surface of the base plate 3. Multiple sets of through holes 56 are formed through the supporting surface of the slotted plate 5, and each through hole 56 corresponds to a bottom position sensor 71. The multiple sets of high position sensors 72 are fixedly connected to the rear side wall of the compartment 1. A bottom capacity display light strip 73 is fixedly connected to the right outer wall of the compartment 1. The bottom capacity display light strip 73 cooperates with the multiple sets of bottom position sensors 71. A top capacity display light strip 74 is fixedly connected to the left outer wall of the compartment 1. The top capacity display light strip 74 cooperates with the multiple sets of high position sensors 72. The bottom capacity display light strip 73 and the top capacity display light strip 74 described above and shown in the figures are also collectively referred to as occupancy indication devices in this document. They are not necessarily light strips that display capacity in the form of light emission, but can also be broadly understood as indication devices that display capacity through one or more of various shapes, patterns, and text. In addition, the arrangement of the light strips 73 and 74 is only an example. Those skilled in the art can also arrange the light strips 73 and 74 in other positions that can be observed even when the luggage compartment lid is fully closed, according to actual needs.

[0113] The bottom position sensors 71 are installed at the bottom of the cabin 1, arranged in two rows, front and back. The perforated plate 5 has through holes 56 for the bottom position sensors 71 to detect objects. A transparent protective plate can be installed over the through holes 56 to prevent debris from obstructing or damaging the bottom position sensors 71. When luggage completely obscures all bottom position sensors 71, it indicates that the bottom space of the cabin 1 is full, and the bottom capacity indicator light bar 73 will all be red. If the bottom space of the cabin 1 is not full, the bottom capacity indicator light bar 73 will display both red and green (the length ratio of the red light bar is determined by the proportion of the number of obscured bottom position sensors 71 to the total number of bottom position sensors 71).

[0114] The function of the high-level sensor 72 is to detect whether the upper space of cabin 1 is occupied. When the height of the placed luggage exceeds the position of the high-level sensor 72, the corresponding high-level sensor 72 will be blocked, indicating that the space is occupied. Conversely, if the height of the luggage is lower than the position of the high-level sensor 72, it means that there is still space available. Similarly, when the luggage completely blocks all the high-level sensors 72, it indicates that the upper space of cabin 1 is full, and the upper-level capacity indicator light bar 74 will all be displayed in red. If the upper space of cabin 1 is not full, the upper-level capacity indicator light bar 74 will be displayed in red and green (the length ratio of the red light bar is determined according to the proportion of the number of blocked high-level sensors 72 to the total number of high-level sensors 72).

[0115] Preferably, the bottom position sensor 71 and the high position sensor 72 can be infrared sensors.

[0116] refer to Figures 25-28 The diagram shows the possible display states of the bottom capacity indicator light bar 73 (right) and the top capacity indicator light bar 74 (left) corresponding to different numbers of luggage, which is easy to understand.

[0117] Please see Figures 1-5 and Figures 18-24 In this embodiment, as another implementation of the present invention, a vertically movable main bulkhead 8 is suspended and installed above the interior of the cabin 1. Scissor-type telescopic frames 9 for supporting the main bulkhead 8 are connected to both the left and right sides of the main bulkhead 8. The upper end of the scissor-type telescopic frames 9 is fixed to the mounting groove 11. The main bulkhead 8 can be raised and lowered by adjusting the scissor-type telescopic frames 9. The scissor-type telescopic frames 9 include two sets of lower fixing bars 91 and four sets of scissor frames 92. The two sets of lower fixing bars 91 are respectively fixedly connected to the left and right sides of the main bulkhead 8. The four sets of scissor frames 92 are respectively connected in pairs to the upper ends of the two sets of lower fixing bars 91. The two sets of scissor frames 92 on the same side are symmetrically arranged and their upper ends are connected to upper fixing bars 93. The two sets of upper fixing bars 93 are respectively fixedly connected to the left and right sides of the mounting groove 11. Sub-bulbs 10 are slidably connected to both the left and right sides of the lower surface of the main bulkhead 8.

[0118] This invention utilizes movable luggage trays, including a main partition 8 and a secondary partition 10. In its initial state, the main partition 8 is folded and stored at the top of the compartment 1, without affecting luggage storage. Only when there is remaining space in the upper layer can the main partition 8 be unfolded downwards, thus dividing the interior of the compartment 1 into layers. This effectively prevents luggage from sliding due to stacking, ensuring stable storage and avoiding space waste caused by lower-layer luggage being less resistant to pressure, thereby optimizing space utilization and storage safety. Furthermore, the pull-down height of the main partition 8 can be precisely adjusted using a scissor-type telescopic frame 9 to better suit the actual height requirements of the stored luggage. The secondary partition 10 can be flexibly unfolded depending on the size of the luggage: if only some luggage is tall, only the main partition 8 needs to be pulled down; while when all luggage is short, the secondary partition 10 can be unfolded to both sides while pulling down the main partition 8, further optimizing space division and making the entire compartment 1 more efficient to use. Adjustment methods for the main partition 8 and the secondary partition 10 corresponding to different luggage placement methods.

[0119] Preferably, long guide rails 81 are fixedly connected to both the front and rear sides of the main partition 8, and the front and rear sides of the sub-partition 10 are slidably connected to two sets of long guide rails 81 respectively. A sliding groove 811 is provided through the front side of the long guide rail 81 located on the front side, and a lever 101 is fixedly connected to the front side of the sub-partition 10. The lever 101 slides through the sliding groove 811 and extends to the front of the long guide rail 81. When it is necessary to unfold the sub-partition 10, the lever 101 can be manually moved to one side, and the lever 101 can drive the sub-partition 10 to move.

[0120] Preferably, the lower fixing strip 91 includes a lower center plate 911 and two sets of limiting recesses 912, for example, in the form of slide rails. The lower center plate 911 is fixedly connected to one side of the main partition plate 8, and the two sets of limiting recesses 912 are respectively fixedly connected to the front and rear sides of the lower center plate 911. The upper fixing strip 93 includes an upper center plate 931 and two sets of upper slide rails 932. The upper center plate 931 is fixedly connected to the inner side of the mounting groove 11, and the two sets of upper slide rails 932 are respectively fixedly connected to the front and rear sides of the upper center plate 931. The scissor bracket 92 is composed of a first support rod 921 and a second support rod 922. The first support rod 921 and the second support rod 922 are rotatably connected at the middle position. The lower end of the first support rod 921 is hinged to a lower ear seat 9211, and the lower ear seat 9211 is fixedly connected to the lower center plate 911. On the upper surface of plate 1, the upper end of support rod 1 921 is hinged to an upper ear seat 9212, and the upper end of upper ear seat 9212 is rotatably connected to an upper pulley 9213. The upper pulley 9213 is slidably connected to the inner side of the upper slide rail 932 at the corresponding position. The upper end of support rod 2 922 is hinged to an upper ear seat 2 9221, and the upper ear seat 2 9221 is fixedly connected to the lower surface of the upper center plate 931. The lower end of support rod 2 922 is hinged to a lower ear seat 2 9222, and the lower end of lower ear seat 2 9222 is rotatably connected to a lower pulley 9223. The lower pulley 9223 is slidably connected to the inner side of the limiting recess 912 at the corresponding position. A locking limiting device 923 for limiting the relative position of the lower pulley 9223 and the limiting recess 912 is connected to the front side of the lower ear seat 2 9222 located on the front side. The locking limiting device 923 is preferably configured to be self-locking. When the main partition 8 needs to be pulled down, it will cause the scissor brackets 92 on both sides to deform. At this time, support rod 1 921 and support rod 2 922 will respectively drive upper ear seat 1 9212 and lower ear seat 2 9222 to move towards the center to adapt to the height change of the main partition 8. During the adjustment process, lower ear seat 2 9222 will drive the locking limit device 923 to slide. When it slides to the desired position, the system can achieve self-locking, thereby fixing the height of the main partition 8 and preventing it from shifting.

[0121] Preferably, the locking and limiting device 923 includes an extension plate 9231 and a hollow fixing seat 9232. The extension plate 9231 is fixedly connected to the front side of the lower ear seat 9222, and the fixing seat 9232 is fixedly connected to the upper surface of the extension plate 9231. Multiple sets of side holes 92321 are opened through the left and right sides of the fixing seat 9232. Connecting plates 9233 are slidably connected to the left and right sides of the interior of the fixing seat 9232. Multiple sets of limiting pins 9234 are fixedly connected to the side of the connecting plate 9233 near the side hole 92321. The limiting pins 9234 are slidably connected to the side hole 92321 at the corresponding position. Two sets of limiting elastic elements 9235 are sandwiched between the two sets of connecting plates 9233. Lower side plates 913 are fixedly connected to the left and right sides of the upper surface of the limiting recess 912. Multiple sets of limiting holes 9131 that cooperate with the limiting pins 9234 for limiting on the opposite side of the two sets of lower side plates 913. During the movement of the lower ear seat 9222, the extension plate 9231 and the fixed seat 9232 move synchronously. During this movement, the limiting pin 9234 is pressed by the lower side plate 913 and pushed into the fixed seat 9232, at which point the limiting elastic element 9235 is in a compressed state. After the position adjustment is completed, the limiting pin 9234 coincides with the corresponding limiting hole 9131, the limiting elastic element 9235 recovers its deformation, and elastically presses the limiting pin 9234 into the limiting hole 9131, thereby achieving the elastic self-locking function of the main partition 8 height.

[0122] Preferably, a rotating limiting post 9236 for restricting the movement of the two sets of connecting plates 9233 can be provided between the two sets of limiting elastic elements 9235 to form a locking knob. The rotating limiting post 9236 is located between the two sets of connecting plates 9233. The lower end of the rotating limiting post 9236 is rotatably connected to the inner bottom wall of the fixed base 9232, and the upper end of the rotating limiting post 9236 rotatably passes through the upper surface of the fixed base 9232. A knob 9237 is fixedly connected to the upper end of the rotating limiting post 9236. After the height of the main partition 8 is adjusted, the knob 9237 is rotated. The knob 9237 will drive the rotating limiting post 9236 to rotate from the unlocked position to the locked position, thereby limiting the position of the two sets of connecting plates 9233. At this time, the limiting pin 9234 will be unable to move, thereby indirectly achieving complete locking of the position of the main partition 8.
