DETAILED DESCRIPTION

[0047] Here, the technical solutions in the embodiments (or "implementations") of the present application will be clearly and completely described in conjunction with the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0048] If there are terms related to directional indications or positional relationships in the embodiments of this application (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationship, movement, etc. between the components in a specific posture (as shown in the accompanying drawings); if the specific posture changes, the directional indication or positional relationship will also change accordingly. In addition, the terms "first" and "second" in the embodiments of this application are only used for the purpose of convenience of description and should not be understood as indicating or implying relative importance.

[0049] refer to Figures 1 to 4 The present application provides a vehicle (not shown) comprising a floor 210 and a bed assembly 100. The bed assembly 100 of the present application comprises a mattress portion 1, a support portion 2, and a base 3. The mattress portion 1 comprises a fixed mattress 11 and a deformable mattress 12 abutting against each other in a first direction X. The support portion 2 is connected to the mattress portion 1. The base 3 is disposed on a side of the support portion 2 away from the mattress portion 1 and extends along a height direction Z. One end of the base 3 is connected to the support portion 2, and the other end is connected to the floor 210.

[0050] The bed assembly 100 has an expanded state and a collapsed state. When the bed assembly 100 is in the expanded state, the dimension of the deformable mattress 12 in the first direction X is a first distance D1. When the bed assembly 100 is in the collapsed state, the dimension of the deformable mattress 12 in the first direction X is a second distance D2. The first distance D1 is greater than the second distance D2.

[0051] Through this configuration, the mattress portion 1 of the bed assembly 100 of the present application can change its size in the first direction X, allowing vehicle occupants to select the width of the mattress portion 1 according to their rest needs, thereby improving rest comfort. Furthermore, the provision of the deformable mattress 12 allows the bed assembly 100 to be retracted and stored when not in use, thereby freeing up space in the vehicle cabin and avoiding the space occupation problem caused by the widening of the bed assembly 100. The mattress portion 1 is typically composed of a material with a certain degree of flexibility and elasticity, such as springs and sponge, or rubber. Therefore, the provision of the support portion 2 can provide a certain degree of rigidity support for the mattress portion 1, further improving the lying comfort of the bed assembly 100. In addition, the provision of the base 3 raises the distance between the mattress portion 1 and the floor 210, not only forming a storage space 4 between the floor 210 and the support portion 2 of the bed assembly 100, improving space utilization in the height direction Z, but also making it easier for the occupants to lie down and stand up.

[0052] It should be noted that for the sake of simplicity and clarity, this application uses the first direction X, the second direction Y, and the height direction Z as reference directions. In the embodiment shown in the accompanying drawings, the first direction X, the second direction Y, and the height direction Z are perpendicular to each other. However, this is intended to be illustrative and not restrictive. In other embodiments, any two of the first direction X, the second direction Y, and the height direction Z can be at any angle. This application does not limit this.

[0053] When the bed assembly 100 is assembled in a vehicle, the fixed mattress 11 is positioned adjacent to the vehicle's rear panel (not shown). This creates a three-way enclosed storage space 4 between the rear panel, floor 210, and support portion 2. This ensures that items in the storage space 4 remain fixed in place, preventing items in the storage space 4 from moving out of the storage space 4 in the first direction X from one side of the fixed mattress 11 due to inertia caused by changes in vehicle speed during travel.

[0054] Furthermore, in an optional embodiment, the vehicle includes a closing plate (not shown). One end of the closing plate is connected to the floor 210, and the other end abuts the support portion 2. The closing plate is provided on the side of the bed assembly 100 away from the fixed mattress 11, and together with the rear panel, closes the storage space 4 in the first direction X. In other words, the storage space 4 is closed on both sides in the first direction X by the rear panel and the closing plate, respectively. This embodiment can further ensure that items are placed in the storage space 4, and prevent the items in the storage space 4 from leaving the storage space 4 due to inertia due to speed changes during vehicle driving. At the same time, this arrangement can prevent the items in the storage space 4 from leaving the storage space 4 when the vehicle is hit, causing secondary injuries to the occupants, thereby helping to improve the safety of the vehicle.

[0055] As for how to store and retrieve items from the enclosed storage space 4, in some embodiments, the enclosing panel may be a multi-piece structure, and corresponding guide rails are provided on the floor 210 to enable translational movement of the enclosing panel, for example, along the second direction Y. Alternatively, the enclosing panel may be pivotally connected to a structure such as the floor 210, thereby enabling opening and closing movement of the enclosing panel under the action of a force in the first direction X.

[0056] In an optional embodiment, the bed assembly 100 further includes a pivot portion 6. The pivot portion 6 includes a first connection portion 61 and a second connection portion 62 that are pivotally connected. The first connection portion 61 is connected to the support portion 2 at one end away from the deformable mattress 12 in the first direction X. The second connection portion 62 is connected to the rear panel of the vehicle. Figure 1 As shown, by providing the pivot portion 6, the support portion 2 and the mattress portion 1 can pivot under the action of the first connection portion 61 and the second connection portion 62, that is, pivot with the rear panel. In this embodiment, the connection between the base 3 and the support portion 2 is abutting connection, not a fixed connection.

[0057] In this manner, the support portion 2 and mattress portion 1 can pivot away from the base 3 to expose the storage space 4, or pivot toward the base 3 to enclose the storage space 4. This arrangement eliminates the need for additional rails or other structures in the vehicle to enable the closing panel to move and expose the storage space 4. Furthermore, the pivoting and opening of the first and second connecting portions 61, 62 requires the application of a force in the height direction Z away from the floor 210. Since the force applied to a vehicle by an external impact is typically directed in the first direction X or the second direction Y, this embodiment can, to a certain extent, prevent items in the storage space 4 from leaving the storage space 4 when the vehicle is impacted, thereby improving storage security.

[0058] It should be noted that in the embodiment where the bed assembly 100 includes the pivot portion 6, the deformable mattress 12 and the fixed mattress 11 are connected in the first direction X, which should be understood as the connection state when the mattress portion 1 is not pivoted away from the base 3, and should not be understood as the connection state when the mattress portion 1 is Figure 1 The connection status at the indicated state.

[0059] In order to satisfy passengers of different ages, body shapes and genders to be able to operate the pivoting of the mattress part 1 and the support part 2, in one embodiment, as shown in FIG. Figure 5As shown, the bed assembly 100 includes a gas strut 7. The gas strut 7 includes a first end 71 connected to the base 3 and a second end 72 connected to the support portion 2. The gas strut 7 is configured to apply a force from the first end 71 toward the second end 72 to the support portion 2. When the mattress portion 1 and the support portion 2 need to pivot away from the base 3, the gas strut 7 applies a force from the first end 71 toward the second end 72 to the support portion 2, thereby assisting the occupant in pushing the mattress portion 1 and the support portion 2 away from the base 3. When the occupant needs to close the mattress portion 1 and the support portion 2, the gas strut 7 continues to apply a force from the first end 71 toward the second end 72 to the support portion 2, slowly moving the mattress portion 1 and the support portion 2 toward the base 3. This prevents the mattress portion 1 and the support portion 2 from closing quickly due to insufficient strength, which could cause unusual noises or even pinching or bruising to the occupant. Thus, the provision of the gas strut 7 helps improve the safety of the bed assembly 100 during pivoting and opening, as well as ease of operation.

[0060] The bed assembly 100 can be connected to the vehicle by the base 3 alone, or by the base 3 and the rear panel alone in an embodiment with a pivot 6. Figures 2 to 4 As shown, in some embodiments, the vehicle includes a side panel 220 and a first supporting portion 230 provided on the side panel 220. The first supporting portion 230 is connected to the support portion 2 at the end portion in the second direction Y of the fixed mattress 11. The provision of the first supporting portion 230 can further distribute the weight of the bed assembly 100 to the side panel 220 for stress bearing, thereby reducing the requirements for the structural strength of the base 3, and further improving the connection stability of the bed assembly 100 in the vehicle. In addition, since the position of the fixed mattress 11 in the first direction X remains unchanged, the first supporting portion 230 is correspondingly provided at the end portion of the fixed mattress 11 in the second direction Y, and there is no need to consider the need for the connection between the support portion 2 and the first supporting portion 230 to allow the relative positions of the two to change.

[0061] The first supporting portion 230 may be provided at only one end of the fixed mattress 11 in the second direction Y, or at both ends. There may also be multiple first supporting portions 230 at one end, thereby further improving the supporting stability of the first supporting portion 230 on the bed assembly 100. In addition, the first supporting portion 230 may be directly connected to the side panel 220. Or as Figure 4 As shown, the vehicle is equipped with a support bracket 231 connected to the floor 210 and disposed within the side panels 220. A first support portion 230 is disposed at the end of the support bracket 231 away from the floor 210. The support bracket 231, connected to the first support portion 230, is capable of bearing the force in the height direction Z exerted on the side panels 220 by the weight of the bed assembly 100, thereby preventing deformation of the side panels 220 and improving structural stability.

[0062] Because the side panels 220 are typically curved, it is difficult for the fixed mattress 11 to completely fill the gap between them and the side panels 220. This gap can easily cause small items placed on the bed assembly 100 by the occupant to fall into it. Therefore, in some embodiments, the mattress portion 1 also includes a deformable caulking pad 13. The caulking pad 13 is positioned between the fixed mattress 11 and the side panels 220. Due to its deformable nature, it can adapt to the shape of the side panels 220, thereby filling the gap between the fixed mattress 11 and the side panels 220. The caulking pad 13 can be made of materials such as sponge or rubber. Furthermore, there is no fixed connection between the caulking pad 13 and the fixed mattress 11. In other words, the occupant can remove the caulking pad 13 from the gap as needed. The provision of the caulking pad 13 not only prevents items from falling into the gap between the side panels 220 and the fixed mattress 11, but also further expands the reclining area of ​​the mattress portion 1 in the second direction Y, thereby improving space utilization.

[0063] Similarly, in order to achieve the movement of the deformable mattress 12 in the first direction X, it is difficult to set the deformable mattress 12 to a shape that "fits perfectly" with the multi-curved side panels 220. Therefore, the filling pad 13 can also be set between the deformable mattress 12 and the side panels 220 when the bed assembly 100 is in the unfolded state, and is used to fill the gap between the deformable mattress 12 and the side panels 220, thereby increasing the lying area of ​​the mattress part 1.

[0064] Regarding the size change of the deformable mattress 12 in the first direction X, in some embodiments, the deformable mattress 12 includes a plurality of through holes 12 extending along the height direction Z. When the bed assembly 100 switches between the expanded state and the collapsed state, the diameter of the through holes 12 changes. Figure 2 and Figure 3 As shown, Figure 2 The bed assembly 100 is in a contracted state, and the diameter of the through hole 12 of the deformable mattress 12 is significantly smaller than Figure 3 The bed assembly 100 is in its unfolded state. With this configuration, the deformable mattress 12 can be configured as a mattress with various materials, such as a sponge or rubber pad. Compared to air mattresses, mesh mattresses, and other mattresses, the deformable mattress 12 of this embodiment can further enhance sleeping comfort, thereby satisfying the occupant's rest needs. Furthermore, the through-holes 12 are simple to manufacture, reducing the manufacturing cost of the deformable mattress 12.

[0065] This application does not limit the number or diameter of through-holes 12. Increasing the number of through-holes 12 or increasing their diameters increases the deformability of the deformable mattress 12. Reducing the number of through-holes 12 or decreasing their diameters increases the support provided by the deformable mattress 12 to the human body. Those skilled in the art can determine the desired degree of deformation of the deformable mattress 12 based on the space within the vehicle cabin and select the number and diameter of through-holes 12 accordingly. Furthermore, the support of the deformable mattress 12 can also be adjusted by its thickness in the height direction Z.

[0066] In other embodiments, the deformable mattress 12 may also have a folding structure such as a fan shape, so as to achieve a size change of the deformable mattress 12 in the first direction X.

[0067] When the bed assembly 100 is switched to the unfolded state, the deformable mattress 12 can maintain its stability only by the support portion 2. Figure 2 and Figure 3 As shown, in some embodiments, the vehicle includes a second supporting portion 240 disposed on the side panel 220. When the bed assembly 100 is in the deployed state, the end of the second supporting portion 240 in the second direction Y of the deformable mattress 12 is connected to the support portion 2. In this way, the second supporting portion 240 can bear the force of the bed assembly 100 in the height direction Z when the bed assembly 100 is in the deployed state, preventing the bed assembly 100 from being damaged by the bending moment caused by gravity when the occupant lies or sits on the end of the deformable mattress 12 away from the fixed mattress 11. At the same time, the second supporting portion 240 is disposed on the side panel 220, so that when the bed assembly 100 is in the retracted state, the second supporting portion 240 does not excessively occupy space in the vehicle cabin.

[0068] In order to achieve the movement of the deformable mattress 12 in the first direction X, in some embodiments, the bed assembly 100 also includes a slide rail portion 5. The slide rail portion 5 includes a first sliding unit 51 and a second sliding unit 52 that are slidably connected along the first direction X. The first sliding unit 51 abuts the base 3. The second sliding unit 52 is fixedly connected to the support portion 2. The provision of the slide rail portion 5 can reduce the friction between the support portion 2 and the base 3 during the movement of the deformable mattress 12 in the first direction X, which is beneficial to increasing the service life of the base 3 and the support portion 2 and reducing the noise generated by friction during movement. The provision of the slide rail portion 5 can also reduce the force required to move the deformable mattress 12, so that occupants of different body shapes, genders, and ages can easily switch the bed assembly 100 between the expanded state and the contracted state, thereby improving the occupant's user experience.

[0069] Compared to embodiments in which guide rails are provided on the side panels 220 to enable movement of the support portion 2, the provision of the slide rail portion 5 on the base 3 allows the bed assembly 100 to be assembled as a whole before being installed in the vehicle, eliminating the need to first assemble a portion of the guide rails on the vehicle and then assemble the corresponding guide rails of the bed assembly 100 onto the vehicle's guide rails. Furthermore, compared to the multi-curved side panels 220, the base 3 and support portion 2 can more conveniently be provided as a flat surface, serving as the mounting surface for the slide rail portion 5.

[0070] refer to Figure 5 and Figure 6 In some embodiments, the rail portion 5 includes a fixedly connected locking structure 53 and a rail handle 54. The first sliding unit 51 includes a first slot 511 and a second slot 512 distributed along the first direction X. When the bed assembly 100 is in the extended state, the locking structure 53 is located in the first slot 511. When the bed assembly 100 is in the collapsed state, the locking structure 53 is located in the second slot 512. The locking structure 53 is pivotally connected to the second sliding unit 52, and the rail handle 54 allows the locking structure 53 to pivot out of the first slot 511 or out of the second slot 512. The rail handle 54 and the locking structure 53 effectively lock the rail portion 5, preventing noise caused by the back-and-forth relative movement of the first and second sliding units 51, 52 in the first direction X during vehicle travel due to speed. Furthermore, the rail handle 54 provides a point of force for the occupant to apply to the bed assembly 100, making it easier for the occupant to push or pull the second sliding unit 52.

[0071] When the occupant needs to switch the bed assembly 100 from the retracted state to the expanded state, he first presses the slide rail handle 54, thereby driving the locking structure 53 and the second sliding unit 52 to pivot and leave the second slot 512, and then pulls the slide rail handle 54 to apply a force in the first direction X away from the fixed mattress 11 to the second sliding unit 52, thereby realizing the expansion of the deformable mattress 12.

[0072] When the occupant needs to switch the bed assembly 100 from the expanded state to the collapsed state, he first presses the slide rail handle 54, thereby driving the locking structure 53 and the second sliding unit 52 to pivot and leave the first slot 511, and then pushes the slide rail handle 54 to apply a force in the first direction X to the second sliding unit 52 to fix the mattress 11, thereby achieving the contraction of the deformable mattress 12.

[0073] Admittedly, in an embodiment where the locking structure 53 is not provided, a damping structure may also be provided between the first sliding unit 51 and the second sliding unit 52 to control the sliding damping force between the first sliding unit 51 and the second sliding unit 52, thereby avoiding unexpected relative movement of the first sliding unit 51 and the second sliding unit 52 during vehicle driving.

[0074] Furthermore, in an optional embodiment, the first sliding unit 51 further includes a plurality of intermediate slots 513. The plurality of intermediate slots 513 are disposed between the first slot 511 and the second slot 512 and are spaced apart from each other along the first direction X. The first slot 511 and the second slot 512 can be considered to have two positions: an expanded position and a collapsed position. By providing the plurality of intermediate slots 513, the second sliding unit 52 and the first sliding unit 51 can be fixed at different relative positions, allowing the deformable mattress 12 to be maintained at a plurality of positions between the first distance D1 and the second distance D2. In this manner, the bed assembly 100 allows the occupant to select the expanded size of the deformable mattress 12 based on the desired sleeping area. Furthermore, this arrangement allows the bed assembly 100 to be deployed within a limited space even when the cabin is occupied by objects, preventing it from being deployed, thereby enhancing the adaptability of the bed assembly 100 in various situations.

[0075] like Figure 4 and Figure 5 As shown, there are two bases 3. And the ends of the bases 3 away from the floor 210 are respectively provided with a slide rail portion 5. However, it should be noted that since the movement directions of the slide rail portions 5 are the same, the bed assembly 100 can have only one slide rail portion 5 provided with a locking structure 53 and a slide rail handle 54. Figure 4 The illustrated embodiment and Figure 4 , the left side slide rail portion 5 is provided with a slide rail handle 54, and the right side slide rail portion 5 is not provided with a slide rail handle 54. In this embodiment, the bed assembly 100 includes a fixed handle 92 fixedly connected to the support portion 2. The fixed handle 92 is provided on the right side, so that the occupant can apply a pulling force or a pushing force along the first direction X to the support portion 2 on both sides. The provision of the fixed handle 92 can further increase the occupant's force application points on the bed assembly 100, thereby improving the ease with which the occupant can operate the bed assembly 100 to switch between the expanded state and the retracted state.

[0076] Indeed, Figure 4 and Figure 5 The embodiment shown should be taken as an example and not as a limitation. In other embodiments, there may be only one base 3, and the number of the slide rails 5 provided on the base 3 may be only one or more. Figure 4 In the illustrated embodiment, the number of the rail handles 54 may correspond to the number of the rail sections 5, or the rail handles 54 may be provided on the right side and the fixed handle 92 may be provided on the left side. This application does not limit this.

[0077] In some embodiments, there may be only one support portion 2. The support portion 2 can move with the deformable mattress 12, moving relative to the fixed mattress 11. Alternatively, the support portion 2 can remain fixedly connected to the fixed mattress 11, while the deformable mattress 12 and the support portion 2 can move relative to each other.

[0078] Or, as Figure 4 As shown, in some embodiments, the support portion 2 includes a first support plate 21 and a second support plate 22. The first support plate 21 is disposed on the side of the fixed mattress 11 facing the base 3 and is connected to the fixed mattress 11. The second support plate 22 is disposed on the side of the deformable mattress 12 facing the base 3 and is fixedly connected to one side of the deformable mattress 12 in the first direction X. This arrangement provides rigid support for both the deformable mattress 12 and the fixed mattress 11, thereby improving the structural stability of the mattress portion 1 and the support provided to the user.

[0079] In the embodiment where the bed assembly 100 includes the slide rail portion 5, the second sliding unit 52 is fixedly connected to the second support plate 22. This arrangement allows the second sliding unit 52 to move the second support plate 22 without affecting the first support plate 21. Therefore, this arrangement further reduces the impact of the deformable mattress 12 on the fixed mattress 11 during movement.

[0080] Furthermore, the first sliding unit 51 can be fixedly connected to the base 3 or fixedly connected to the first support plate 21. In an embodiment in which the bed assembly 100 includes both the slide rail portion 5 and the pivot portion 6, the first sliding unit 51 is fixedly connected to the first support plate 21 and is detachable from the base 3. When the support portion 2 and the mattress portion 1 pivot away from the base 3, the slide rail portion 5 follows the support portion 2 and moves away from the base 3. When the support portion 2 and the mattress portion 1 pivot toward the base 3, the slide rail portion 5 follows the support portion 2 and approaches the base 3, and eventually the first sliding unit 51 abuts against the base 3, so that the base 3 supports the mattress portion 1 and the support portion 2 in the height direction Z.

[0081] In the embodiment where the bed assembly 100 further includes a gas strut 7, the second end 72 of the gas strut 7 is connected to the first sliding unit 51, and the gas strut 7 is indirectly connected to the support portion 2. In this way, the gas strut 7 can assist the support portion 2 in pivoting.

[0082] To further optimize the volume occupied by the bed assembly 100, as Figure 4As shown, in some embodiments, the second support plate 22 includes an escape groove 221 for circumventing the second sliding unit 52. The escape groove 221 extends away from the fixed mattress 11 along the first direction X at the end of the second support plate 22 facing the fixed mattress 11. This arrangement allows the slide rail portion 5 to be at least partially accommodated in the escape groove 221, thereby reducing the dimension occupied by the support portion 2 and the slide rail portion 5 in the height direction Z.

[0083] In embodiments where the support portion 2 includes a first support plate 21 and a second support plate 22 , the first support plate 21 and the second support plate 22 optionally at least partially overlap in the first direction X when the bed assembly 100 is in the deployed and collapsed states. This allows the first and second support portions 2 and 2 to still fully support the fixed mattress 11 and the deformable mattress 12 when the bed assembly 100 is in the deployed state. Compared to an embodiment in which a gap exists between the first and second support plates 21 and 22 in the first direction X when the bed assembly 100 is in the deployed state, this embodiment further ensures the rigid support provided by the support portion 2 to the mattress portion 1, thereby enhancing the comfort level provided by the bed assembly 100.

[0084] exist Figure 4 In the illustrated embodiment, the first support plate 21 is positioned closer to the mattress portion 1 than the second support plate 22 in the height direction Z. Therefore, to facilitate assembly of the bed assembly 100, the first support plate 21 is provided with a relief groove 211. The relief groove 211 exposes the second support plate 22, thereby facilitating assembly and connection of the second support plate 22. In embodiments where the second support plate 22 includes the relief chute 221, the relief groove 211 and the relief chute 221 can be directly connected in the height direction Z, thereby exposing the rail portion 5 or the base 3 for easier installation.

[0085] In an optional embodiment, the bed assembly 100 further includes fabric and a rolling portion 8. The rolling portion 8 is provided on the side of the deformable mattress 12 away from the fixed mattress 11. One end of the fabric is connected to the side of the fixed mattress 11 away from the deformable mattress 12, and the other side is connected to the rolling portion 8. The rolling portion 8 is used to roll up the fabric. The fabric is used to cover the mattress portion 1, thereby concealing the deformable structure of the deformable mattress 12 and improving the aesthetics of the bed assembly 100. Since the size of the deformable mattress 12 in the first direction X switches between the first distance D1 and the second distance D2, in order to completely cover the mattress portion 1, the fabric needs to be able to cover the mattress portion 1 when the bed assembly 100 is in the expanded state. However, when the bed assembly 100 switches to the contracted state, there will be excess fabric. Therefore, the provision of the rolling portion 8 can be used to roll up excess fabric, thereby maintaining the neatness of the bed assembly 100.

[0086] The retracting portion 8 can be manually operated, that is, the occupant needs to manually rotate the reel of the retracting portion 8 to achieve the retraction of the fabric. Alternatively, the retracting portion 8 can also be electric, and the fabric retraction is achieved by rotating the motor. Alternatively, the retracting portion 8 can also be provided with an elastic member that enables the reel to keep the fabric rolled up and recovered. When the bed assembly 100 switches from the deployed state to the stowed state, the action of the elastic member enables the reel to achieve the retraction of the fabric. When the bed assembly 100 switches from the stowed state to the deployed state, the occupant needs to overcome the force exerted by the elastic member to achieve the state switching of the bed assembly 100.

[0087] In order to avoid the retracted portion 8 affecting the comfort of the occupant when lying down, Figure 4 As shown, in one embodiment, the deformable mattress 12 includes a storage slot 122. The storage slot 122 is located on the side of the deformable mattress 12 facing the support portion 2 and on the side away from the fixed mattress 11. The roll-up portion 8 is located within the storage slot 122. This arrangement allows the roll-up portion 8 to be concealed on the side of the deformable mattress 12 facing the base 3. Furthermore, the storage slot 122 is also located on the side of the deformable mattress 12 away from the fixed mattress 11. This arrangement minimizes the amount of fabric covering the side of the mattress portion 1 facing the support portion 2, thereby reducing fabric costs.

[0088] The connection between the fabric and the fixed mattress 11 can be detachable. Simultaneously, the connection between the fabric and the retractable portion 8 can also be detachable. This allows the fabric to be removed from the bed assembly 100, allowing the occupant to regularly clean the fabric, thereby improving the hygiene of the bed assembly 100.

[0089] In some embodiments, the bed assembly 100 further includes a cover plate 91. The cover plate 91 is disposed at the end of the retractor 8 in the second direction Y, thereby shielding the internal structure of the retractor, improving the overall visual effect of the bed assembly 100, and also preventing the presence of sharp structures inside the retractor 8 from causing harm to the human body.

The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of this application shall be included in the scope of protection of this application.
