Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cab interior, in particular to a turnover pull-out baffle structure, a sleeping berth and a vehicle. BACKGROUND

[0002] In the field of commercial vehicles, a storage box is usually arranged under the sleeping berth for storing personal items of passengers, so as to improve the space utilization and use convenience of the vehicle cabin. The mainstream storage box structures in this field are mainly divided into two types, namely fixed baffle type and drawer type, each of which has limitations in use experience.

[0003] The fixed baffle type storage box has the advantages of simple structure, but also has obvious defects. When the passenger takes or puts the items, the bedding needs to be arranged first and then the sleeping berth is turned over, which is cumbersome. If there is a passenger resting on the sleeping berth, this process will directly interfere with the passenger, seriously affecting the comfort of the ride.

[0004] The drawer type storage box realizes the storage and taking of items through the sliding of the drawer, which effectively avoids the problem of turning over the sleeping berth and does not need to interfere with the resting passenger, but the storage space is greatly compressed due to the design characteristics of the sliding structure, which is difficult to meet the storage demand of more items. SUMMARY

[0005] Embodiments of the present application provide a turnover pull-out baffle structure, a sleeping berth and a vehicle to solve the problem that the sleeping berth cannot achieve a balance between the storage space, use convenience and ride comfort in the related art.

[0006] In a first aspect, a turnover pull-out baffle structure is provided, which comprises: a guide rail assembly comprising symmetrically arranged guide rails, and a sliding part slidingly connected to the guide rails; a baffle assembly comprising a baffle and a limiting part symmetrically arranged on both sides of the baffle, and the limiting part is rotationally connected to the sliding part through a pin shaft; wherein a limiting groove is arranged on the sliding part, and a locking pin is arranged on the limiting part; when the baffle is turned around the pin shaft to be parallel to the guide rail assembly, the locking pin is clamped into the limiting groove.

[0007] In some embodiments, the limiting groove is made of an elastic material, and / or the locking pin is made of an elastic material.

[0008] In some embodiments, at least one end of the guide rail is provided with a first locking part. When the sliding part slides to contact the first locking part, the first locking part provides a locking force to limit the movement of the sliding part.

[0009] In some embodiments, the first locking part is an elastic protruding point or an elastic arm protruding towards the inner side of the guide rail.

[0010] In some embodiments, the guide rail is rotatably connected with a pulley on one side.

[0011] In some embodiments, the limiting groove protrudes from the sidewall of the guide rail.

[0012] In some embodiments, the baffle is provided with a handhold.

[0013] In a second aspect, a bunk is provided, which is installed with the turnover pull-out baffle structure.

[0014] In some embodiments, the bunk comprises: a bunk support beam assembly, on which the guide rail assembly is fixedly installed; the baffle assembly is provided with a locking tongue; when the baffle assembly is turned over to be perpendicular to the guide rail assembly, the locking tongue is engaged with the bunk support beam assembly.

[0015] In a third aspect, a vehicle is provided, which is installed with the bunk.

[0016] The embodiments of the present application provide a turnover pull-out baffle structure, a bunk and a vehicle. Since a limiting part is fixedly connected to the baffle, a sliding part is provided on the guide rail, and the limiting part and the sliding part are rotatably connected through a pin shaft, the baffle can rotate around the pin shaft. In the initial state, the baffle is perpendicular to the guide rail, forming a closed state. When it is needed to take out the articles, the baffle is turned over around the pin shaft to be parallel to the guide rail assembly, so that the locking pin on the baffle is clamped into the limiting groove of the sliding part to achieve locking; then the baffle is pushed in the direction of the guide rail, driving the sliding part to move to the other end, so that the baffle is folded, facilitating the user to store and take out the articles.

[0017] Compared with the traditional drawer mode, the present application does not need to set a square box body structure, but only needs to turn over and slide a baffle to achieve the opening and closing of the storage space, which not only simplifies the structure, but also significantly improves the utilization rate of the storage space. At the same time, the user does not need to get up when taking out the articles, effectively improving the convenience and comfort of use. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0021] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described below in connection with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0022] The embodiments of the present application provide a flip-pull baffle structure, which can solve the problem that a sleeping berth cannot achieve a balance between storage space, use convenience and ride comfort in the related art.

[0023] As shown in Figures 1 to 8 A flip-pull baffle structure, comprising: A guide rail assembly 1, comprising symmetrically arranged guide rails 101, each guide rail 101 being provided with a starting end and a terminal end and being slidingly connected with a sliding part 102, the sliding part 102 being capable of performing pull-out movement along the extension direction of the guide rail 101, wherein the starting end is the end close to a person and the terminal end is the end away from the person; The baffle assembly 2 includes a baffle 201 and limiting parts 202 symmetrically arranged on both sides of the baffle 201, and the limiting parts 202 are rotationally connected with the sliding parts 102 through pin shafts 203, so that the whole baffle 201 can be flipped around the axis of the pin shaft 203. The limiting groove 104 is arranged on the sliding part 102, and the locking pin 204 is arranged on the limiting part 202; when the baffle 201 is flipped to be parallel to the guide rail assembly 1, the locking pin 204 is clamped into the limiting groove 104. This design can make the baffle 201 and the sliding parts 102 on both sides form a relatively stable whole, avoid the baffle from deviating or jamming due to uneven force on both sides when the sliding parts 102 are pulled along the guide rail 101, ensure the synchronization and smoothness of the whole pulling process, and effectively improve the stability of the structure movement and the operation feeling.

[0024] The embodiment of the application provides a flipping and pulling baffle structure. The baffle 201 is fixedly connected with the limiting part 202, the guide rail 101 is provided with the sliding part 102, the limiting part 202 is rotationally connected with the sliding part 102 through the pin shaft 203, so that the baffle 201 can rotate around the pin shaft 203. In the initial state, the baffle 201 is perpendicular to the guide rail 101, forming a closed state. When the article needs to be taken out, the baffle 201 is flipped around the pin shaft 203 to be parallel to the guide rail assembly 1, so that the locking pin 204 on the baffle 201 is clamped into the limiting groove 104 of the sliding part 102 to realize locking; then the baffle 201 is pushed in the direction of the guide rail 101, driving the sliding part 102 to move to the other end, so that the baffle 201 is folded, facilitating the user to store and take out the article.

[0025] Compared with the traditional drawer mode, the application does not need to set a square box body structure, but only needs to flip and slide a baffle 201 to realize the opening and closing of the storage space, which not only simplifies the structure, but also significantly improves the utilization rate of the storage space. At the same time, the user does not need to get up when taking out the article, effectively improving the convenience and comfort of use.

[0026] Further, the limiting groove 104 is made of elastic material, and / or the locking pin 204 is made of elastic material.

[0027] In some embodiments, the limiting groove 104 is made of plastic or rubber with elastic performance. When the baffle 201 is flipped to be parallel to the guide rail assembly 1, the locking pin 204 moves and is pressed into the entrance of the limiting groove 104. The elastic limiting groove 104 is slightly elastically deformed under the extrusion of the locking pin 204, so as to generate a certain clamping force, so that the locking pin 204 is tightly held in the groove, realizing the clamping action with damping feeling and the stable locking state, and avoiding the noise generated by rigid collision.

[0028] In some embodiments, the locking pin 204 is made of elastic material itself, which can be designed as a solid elastic column or a pin with a hollow buffer structure. When the baffle 201 is flipped to the locking position, the elastic locking pin 204 first contacts the rigid groove wall of the limiting groove 104. Through its compression or bending deformation, the locking pin 204 can smoothly slide into the limiting groove 104. Its springback characteristics can effectively fill the fitting gap, eliminate the swing, and make the locking more stable and quiet.

[0029] In some embodiments, the limiting groove 104 and the locking pin 204 are both made of elastic material. During the locking process, both of them undergo a slight elastic deformation, and the locking pin 204 is clamped into the limiting groove 104. This double elastic structure provides excellent tolerance capability, which can effectively compensate for the slight deviation in part manufacturing and assembly, and is suitable for scenes with high frequency operation or higher vibration environment requirements.

[0030] Further, at least one end of the guide rail 101 is provided with a first locking portion 105; When the sliding part 102 slides to contact the first locking portion 105, the first locking portion 105 provides a locking force to limit the movement of the sliding part 102.

[0031] In the present embodiment, the starting end and the ending end of the guide rail 101 are both provided with the first locking portion 105.

[0032] As shown in Figure 1 , the baffle 201 is pulled to the starting end of the guide rail 101 by the handle 206 on the baffle 201, the sliding part 102 is clamped by the first locking portion 105, then a downward rotating force is applied to the baffle 201, the locking pin 204 on the baffle 201 is disengaged from the limiting groove 104, rotates around the pin shaft 203, the locking tongue 205 is engaged with the bunk support beam assembly 3, and the locking of the baffle 201 in the vertical direction is realized.

[0033] As shown in Figure 2 , when the baffle 201 is flipped, the handle 206 is pulled, the locking tongue 205 is disengaged from the bunk support beam assembly 3, and the handle 206 is continuously pulled to rotate around the pin shaft 203 until the locking pin 204 is clamped into the limiting groove 104.

[0034] As shown in Figure 3 , the baffle 201 is extended and retracted, the baffle 201 is pushed to make the sliding part 102 overcome the resistance of the first locking portion 105 and slide in the guide rail 101 until the sliding part 102 abuts against the first locking portion 105 of the ending end.

[0035] When the baffle 201 is engaged with the bunk support beam assembly 3 by rotating the locking tongue 205, it is necessary to ensure that the sliding part 102 is completely fixed at the starting end. If there is no first locking part 105 at this position, the baffle 201 may slide along the guide rail 101 unexpectedly under vertical force, resulting in that the baffle 201 cannot be rotated, the locking tongue 205 cannot be engaged with the bunk support beam assembly 3, the vertical locking function is lost, and a safety hazard is caused. When the baffle 201 slides to the terminal end, i.e. in the telescopic storage state, the first locking part 105 at the terminal end is used to limit the movement of the sliding part 102, so as to prevent the baffle from sliding back and forth due to inertia under the condition of vehicle driving bumping, vibration and the like, prevent collision and damage to surrounding people who take things, reduce the friction between the sliding part and the guide rail, reduce the degree of component wear, prolong the service life of the overall structure, and the like.

[0036] In some embodiments, the first locking part 105 is an elastic protrusion or an elastic arm protruding towards the inner side of the guide rail 101.

[0037] When the sliding part 102 slides along the guide rail 101 to the end of the guide rail, the elastic protrusion at the end of the guide rail 101 is contacted, an interference fit is formed, and a locking force is generated by the combined action of friction and deformation restoring force.

[0038] In some optional embodiments, the bottom of the sliding part 102 is provided with a groove corresponding to the first locking part 105. When the sliding part 102 is in contact with the first locking part 105, the elastic protrusion is slightly deformed, and then the protrusion is clamped into the groove of the sliding part 102, so as to limit the sliding of the sliding part 102.

[0039] In some optional embodiments, the first locking part 105 adopts a magnetic locking mode. Specifically, a permanent magnet is embedded at the terminal end of the guide rail 101, and a piece of ferromagnetic material (such as iron or steel) is embedded at the corresponding contact position of the sliding part 102. When the sliding part 102 slides to the end of the guide rail, the magnetic attraction force starts to act, and automatically guides it to the final position and is adsorbed. The whole locking process is completely contactless and wearless.

[0040] Further, the guide rail 101 is rotatably connected with a pulley 106 on one side.

[0041] The side wall of the guide rail 101 is rotationally connected with a pulley 106. When the baffle 201 moves to the parallel state, the pulley 106 can be attached to the inner wall of the baffle 201 or a preset sliding groove. When the baffle 201 drives the sliding part 102 to slide along the guide rail 101, the pulley 106 rotates synchronously with the movement of the baffle 201, converting the sliding friction between the two into rolling friction. This can effectively reduce the resistance when the sliding part 102 moves, making the extension and retraction operation of the baffle 201 more convenient and labor-saving. Even after long-term use, it can maintain a smooth running state, avoiding operation jamming or obstruction caused by excessive friction resistance. At the same time, the wear caused by rolling friction is much smaller than that caused by sliding friction, which can reduce the wear of the contact part between the guide rail 101 and the baffle 201, prolong the service life of the components, and reduce the frequency and cost of maintenance and replacement.

[0042] Further, the limiting groove 104 protrudes from the side wall of the guide rail 101.

[0043] The limiting groove 104 protrudes from the side wall of the guide rail 101, and the protruding structure can form a fitting cooperation with the locking pin 204 on the sliding part 102. When the sliding part 102 moves to the target position along the guide rail 101, the locking pin 204 can be quickly clamped into the protruding limiting groove 104, and the locking pin 204 can be limited by the side wall edge of the protrusion to prevent the locking pin 204 from accidentally falling out in the case of vehicle bumping and the like.

[0044] Further, the baffle 201 is provided with a hand 206.

[0045] The baffle 201 is provided with a hand 206, and the hand 206 is divided into two groups and arranged on the upper surface and the lower surface of the baffle 201 respectively. The positions of the two groups of hands are adapted to different working states of the baffle 201. When the baffle 201 is in the vertical locking state, i.e. the locking tongue 205 is engaged with the bunk support beam assembly 3, the operation core is to rotate and unlock the baffle 201. The user can directly hold the hand 206 on the upper surface and pull the baffle 201 to rotate around the pin shaft 203 by using the force point provided by the hand, without the need to find an additional force position. When the baffle 201 is in the horizontal extension state, such as when the sliding part 102 moves along the guide rail 101, the operation focus is to pull the baffle to slide. The hand 206 on the lower surface is convenient for the user to hold and directly pull out the baffle 201, or to push the baffle to overcome the resistance of the first locking part 105 to slide. This design of upper and lower hands can make the user find the most convenient operation position in the vertical and horizontal states of the baffle, avoiding the awkwardness of the hand or the inconvenience of force when operating due to the single position of the hand. At the same time, the clear division of labor of the hands also reduces the operation misjudgment rate, and the user can quickly complete the rotation and sliding action of the baffle without repeated attempts, further improving the convenience of use. Especially when the internal space of the vehicle is limited and the operation posture is limited, the state switching of the baffle can be more efficiently completed.

[0046] The application also provides a sleeper provided with the turnover pull-out baffle structure, and the function and use experience of the sleeper are further improved through the matching design of the baffle structure and the sleeper body.

[0047] Specifically, as shown in the drawings, the sleeper comprises: Figures 1 to 3 The sleeper support beam assembly 3 provides stable support for the sleeper, and the guide rail assembly 1 is fixedly installed on the sleeper support beam assembly 3 by means of bolts or welding, so as to ensure that the guide rail does not displace during the sliding and turnover of the baffle; The baffle assembly 2 is provided with a locking tongue 205; When the baffle assembly 2 is turned over to the vertical state with the guide rail assembly 1, the locking tongue 205 is engaged with the sleeper support beam assembly 3.

[0048] The engagement design of the locking tongue 205 and the sleeper support beam assembly 3 can form a stable mechanical locking when the baffle assembly 2 is turned over to the vertical state, directly transfer the vertical force of the baffle to the sleeper support beam assembly 3, which is a load-bearing structure, avoid the baffle relying on the guide rail or the pin shaft alone to bear the load, prevent the deformation of local components caused by long-term stress, and significantly improve the structural stability of the baffle in the vertical state. At the same time, it can provide reliable shielding for the accommodation cavity. When the vehicle encounters bumps, sudden braking or turning, the clothes, tools and other items in the accommodation cavity below the sleeper are easy to displace due to vibration, and the vertically locked baffle can directly shield the opening of the accommodation cavity, and the engagement of the locking tongue and the support beam can ensure that the baffle will not be accidentally turned over or displaced due to vibration, so as to avoid the items from sliding out of the accommodation cavity and keep the vehicle clean.

[0049] Specifically, the locking tongue 205 on the baffle assembly 2 is connected to the side edge of the baffle 201 by means of integral molding or bolt fixation, and the end is provided with an outwardly protruding engagement part, the size of the engagement part is matched with the pre-set locking hole or groove on the sleeper support beam assembly 3, the end away from the baffle 201 is arc-shaped, and the arc-shaped structure can reduce the friction resistance with the side wall of the support beam during engagement, avoid the engagement from being stuck at the moment, and reduce the collision loss of the components. The root of the locking tongue 205 is elastically connected to the baffle 201 through an elastic connecting piece (such as a spring sheet), and in the natural state, the engagement part keeps the posture of extending outward; when the baffle assembly 2 is turned over to the vertical state with the guide rail assembly 1 around the pin shaft 203, the locking tongue 205 rotates synchronously with the baffle, the engagement part at the end gradually approaches the side wall of the vertical support beam of the sleeper support beam assembly 3, and finally is embedded into the locking hole (or buckled on the edge of the groove) on the support beam under the action of the elastic force, forming a mechanical locking.

[0050] ​In some embodiments, the lock tongue 205 can adopt a telescopic structure, with a hollow sleeve as its main body, a compression spring inside, and a latch pin that can slide axially within the sleeve. The sleeve is fixed to the side edge of the baffle 201, and the latch pin has a head that protrudes out of the sleeve for latching, and the other end is connected with the spring and limited within the sleeve. When the baffle assembly 2 is flipped to the vertical state, the latch pin head first contacts and is pressed by the side wall of the bunk support beam assembly 3, and the compression spring makes the latch pin retract into the sleeve. As the baffle continues to rotate to the preset position, the latch pin head is aligned with the locking groove on the support beam, and the spring resets to push the latch pin out and embed it into the groove, completing the locking.

[0051] In some embodiments, the lock tongue 205 and the latching structure of the bunk support beam assembly 3 adopt a magnetic attraction auxiliary design: the latching part of the lock tongue is embedded with a permanent magnet, and the locking position on the support beam is provided with an iron sheet or another permanent magnet with opposite polarity. When the baffle is flipped to the near-vertical state, the magnetic attraction force will actively guide the lock tongue to align with the locking position, assisting the latching part to accurately embed; and when unlocking, only a pulling force slightly larger than the magnetic attraction force is needed to separate them, which not only improves the smoothness of operation, but also enhances the stability of the locking when the vehicle is slightly shaken, avoiding accidental disengagement under non-human operation.

[0052] It can be understood that the main structure of the bunk is composed of a bunk panel for bearing, two side plates symmetrically arranged at the edges of the bunk panel, a bottom plate (not shown in the figure) located at the bottom, and the baffle 201, which cooperatively form a complete bunk body. Among them, the bunk panel as the core bearing surface can directly place a mattress for personnel to rest, or be used as a temporary storage plane when there is no mattress; the side plates extend vertically along the four edges of the bunk panel to provide vertical enclosure for the formation of the accommodating cavity; and the bottom plate is horizontally laid at the bottom of the bunk and parallel to the bunk panel, finally the bunk panel, the side plates and the bottom plate cooperatively enclose a closed accommodating cavity. The accommodating cavity is located below the bunk panel, fully utilizing the originally idle space below the bunk, and the interior can be used to classify and store articles such as clothes, bedding, travel supplies or maintenance tools, without occupying other storage areas in the car compartment, significantly improving the storage capacity and space utilization rate of the bunk.

[0053] The bunk support beam assembly 3 is the core load-bearing framework of the bunk, which is composed of a horizontal support beam and a vertical support beam: the horizontal support beam is arranged transversely and fixed with the vertical support beam, and the horizontal support beam is directly attached to the top of the bunk panel to provide uniform support force for the panel, avoiding deformation of the panel due to excessive local stress when a person lies down; the vertical support beam is vertically installed between the bottom plate and the horizontal support beam, responsible for transmitting the weight of the horizontal support beam and the bunk panel to the bottom, and enhancing the anti-shaking ability of the entire bunk structure, especially reducing the shaking amplitude of the bunk when the vehicle is driving on a bumpy road.

[0054] In this embodiment, the baffle 201 is arranged on the upper surface of the accommodating cavity, specifically below the horizontal support beam in the bunk support beam assembly 3, and cooperates with the guide rail assembly 1 to realize sliding and overturning. When the baffle 201 is overturned to the vertical state, the side wall opening of the accommodating cavity can be shielded, cooperates with the side plates on both sides, avoids the articles in the accommodating cavity from falling accidentally due to vehicle vibration, sudden braking and the like, and blocks external dust from entering, thereby keeping the storage space clean. When the articles in the accommodating cavity need to be taken, the baffle is only needed to be unlocked, overturned and opened, and pushed to slide along the guide rail, so that the baffle 201 is parallel to the bunk panel, neither occupies external space nor affects the normal use of the bunk panel, the baffle meets the protection function while minimizing the occupation of space, and the simple operation steps further improve the use convenience and structural rationality of the bunk.

[0055] The application also provides a drawer provided with the above-mentioned overturning and pulling baffle structure. Similar to the above-mentioned bunk structure, when the articles in the accommodating cavity need to be taken, the baffle is only needed to be unlocked, overturned and opened, and pushed to slide along the guide rail, so that the baffle 201 is parallel to the drawer panel, neither occupies external space nor affects the normal use of the drawer panel, the baffle meets the protection function while minimizing the occupation of space, and the simple operation steps further improve the use convenience and structural rationality of the drawer.

[0056] The application also provides a vehicle provided with the above-mentioned bunk structure. After the vehicle is provided with the above-mentioned bunk structure, firstly, the limited space inside the vehicle can be efficiently utilized, and the conflict between the storage and the rest function on the vehicle is solved. The accommodating cavity surrounded by the bunk panel, the side plates and the bottom plate can accommodate articles such as clothes, bedding and repair tools under the bunk, without the need of additionally installing an independent storage cabinet, thereby avoiding the occupation of the already tense activity space in the vehicle cabin, especially for vehicles such as trucks and caravans which have high requirements for space utilization, so that the layout inside the vehicle is more regular. Secondly, the rest convenience and operation convenience of the driver and passenger are significantly improved. The bunk panel can stably bear the mattress, thereby providing comfortable rest support for long-distance drivers. The overturning and pulling design of the baffle 201 is as follows. In the initial state, the baffle is perpendicular to the guide rail, thereby forming a closed state. When the articles need to be taken, the baffle is overturned around the pin shaft to be parallel to the guide rail assembly, so that the locking pin on the baffle is clamped into the limiting groove of the sliding part to realize locking. Then, the baffle is pushed in the guide rail direction, thereby driving the sliding part to move to the other end, so that the baffle is folded. The user does not need to get up when taking the articles, thereby effectively improving the convenience and comfort of use.

[0057] Compared with the traditional drawer storage device, on the one hand, the traditional drawer needs to rely on the outer box body to carry the articles, the inner box body is nested in the outer box body, the side plate, back plate and bottom plate of the inner box body have a fixed thickness, and in order to ensure smooth pulling, at least 5-10mm gap is reserved between the inner box body and the outer box body (to avoid pulling jam) - these inner box body structure thickness and reserved gap will occupy the actual available space of the storage area from two dimensions of horizontal and vertical, eventually leading to obvious difference between the storage size and the actual size of the articles that can be accommodated, and the space is wasted obviously.

[0058] And the present application does not need to set the inner box body, directly uses the face plate, side plate and bottom plate of the bunk as the main frame of the storage containing cavity, and only one baffle cooperates with the guide rail to realize the opening and closing of the containing cavity - neither the structure thickness of the inner box body occupies the space, nor the drawer type pulling gap is needed. The space wasted by the thickness of the inner box body and the gap between the box bodies is all converted into the actual available storage space, which greatly improves the space utilization rate, especially for the scene of compact internal space of vehicles.

[0059] On the other hand, the traditional drawer is limited by the box body pulling track, and its opening mode needs to occupy 1.5-2 times the length of the box body outside space, for example, if the drawer is 500mm long, 750-1000mm operation space needs to be reserved in front when pulling open, which will lead to the space around the drawer cannot be fully utilized, and the pulling channel needs to be reserved. The baffle of the present application realizes opening by "turning over + sliding": after the baffle in vertical state is turned over to horizontal, it can be directly slid into the lower part of the bunk face plate, and the whole opening process does not need to occupy additional operation space outside the containing cavity, and the area around the bunk can be completely used for other functional layout.

[0060] Compared with the pure turning over type storage device, the storage space of the pure turning over type storage device is usually directly related to the face plate, and when taking the articles, the mattress, bedding, water cup and other articles placed on the face plate need to be completely cleaned and removed, so as to avoid the articles falling or hindering the face plate turning over in the turning over process. The operation steps are complicated and time-consuming; the baffle of the present application is independent of the bunk face plate, and the baffle is only responsible for controlling the opening and closing of the containing cavity below the bunk, and when taking the articles, it is not necessary to move or clean any article on the bunk face plate - only by turning over and pulling the baffle, the containing cavity can be opened, and the whole process will not affect the articles on the face plate, which greatly simplifies the taking process, especially suitable for the scene of quickly taking articles after long distance driving, and improves the use convenience.

[0061] In summary, compared to drawer-type drawers that require a gap for pulling out and have an inner box that encroaches on space, this invention has no box and no redundant gaps, resulting in a larger storage space. Compared to flip-type drawers that rely on a rotating panel, this invention's baffle is independent of the berth panel, eliminating the need to move objects on the panel when retrieving items, thus saving storage space and not occupying operating space. Drawer-type inner boxes are prone to jamming due to uneven force on both sides, and flip-type panels lack stable support after flipping, making them prone to wobbling. This invention uses a "locking pin + limiting groove" to form a stable whole between the baffle and the sliding part, ensuring that the sliding parts on both sides move synchronously along the guide rail and avoid jamming. At the same time, the locking parts at both ends of the guide rail, the locking tongue, and the engagement with the support beam can resist vehicle bumps and prevent the baffle from loosening and items from falling out.

[0062] The operational process for this application is as follows: like Figure 1 As shown, the baffle 201 is pulled to the starting end of the guide rail 101 by the handle 206 on the baffle 201, the sliding part 102 is locked by the first locking part 105, and then a downward rotational force is applied to the baffle 201. The locking pin 204 on the baffle 201 disengages from the limiting groove 104 and rotates around the pin shaft 203. The locking tongue 205 engages with the sleeper support beam assembly 3, thereby locking the baffle 201 in the vertical direction.

[0063] like Figure 2 As shown, when the baffle 201 flips, the handle 206 is pulled, and the locking tongue 205 disengages from the sleeper support beam assembly 3. The handle 206 is then pulled to rotate around the pin 203 until the locking pin 204 is engaged in the limiting groove 104.

[0064] like Figure 3 As shown, the baffle 201 extends and retracts, pushing the baffle 201 to make the sliding part 102 overcome the resistance of the first locking part 105 and slide in the guide rail 101 until the sliding part 102 abuts against the first locking part 105 at the end, so that the baffle 201 is locked in the horizontal direction.

[0065] In the description of this application, it should be noted that the terms "upper," "lower," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Unless otherwise expressly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0066] It should be noted that, in the present application, the relational terms such as "first" and "second", and the like, are used solely to distinguish one entity or action from another, without necessarily requiring or implying any actual relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can also include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element proceeded by "comprises... a" does not, without more constraints, exclude the existence of additional identical elements in the process, method, article, or apparatus that comprises the element.

[0067] The foregoing is considered as illustrative only of the principles of the application. Numerous modifications and changes will readily occur to those skilled in the art, and the generic principles defined herein can be applied to other embodiments without departing from the spirit or scope of the application. Therefore, the application is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
