DETAILED DESCRIPTION

[0047] Here, the technical solutions in the embodiments (or "implementations") of the present application will be described clearly and completely 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 involving directional indications or positional relationships in the embodiments of the present 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 under a certain 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", "second", etc. involved in the embodiments of the present application are only used for the purpose of convenience of description and cannot be understood as indicating or implying relative importance.

[0049] refer to Figures 1 to 4 The present application provides a vehicle (not shown) including a floor 210 and a bed assembly 100. The bed assembly 100 of the present application includes a mattress portion 1, a support portion 2, and a base 3. The mattress portion 1 includes 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 includes an expanded state and a contracted state: when the bed assembly 100 is in the expanded state, the size of the deformable mattress 12 in the first direction X is a first distance D1; when the bed assembly 100 is in the contracted state, the size 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] By such a configuration, the mattress portion 1 of the bed assembly 100 of the present application can change its size in the first direction X, so that the occupants of the vehicle can choose the width of the mattress portion 1 according to their rest needs, which is conducive to improving the comfort of rest. At the same time, the configuration 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 configuration of the bed assembly 100. The mattress portion 1 is usually composed of materials with certain flexibility and elasticity such as springs and sponges, or rubber, so the configuration 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 configuration of the base 3 raises the distance between the mattress portion 1 and the floor 210, not only forming a storage space 4 of the bed assembly 100 between the floor 210 and the support portion 2, but also improving the space utilization rate in the height direction Z, and the elevated mattress portion 1 can also facilitate the occupants to lie down and get up.

[0052] It should be noted that, for the sake of simplicity and clarity of description, the present application sets a first direction X, a second direction Y, and a 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 should be taken as an example and not a limitation. In other embodiments, any two of the first direction X, the second direction Y, and the height direction Z can be at any angle. The present application does not limit this.

[0053] When the bed assembly 100 is assembled in a vehicle, the fixed mattress 11 is disposed close to the rear panel (not shown) of the vehicle. Thus, a three-way surrounded storage space 4 is formed between the rear panel, the floor 210 and the support portion 2, which can ensure that the position of the items in the storage space 4 is fixed, and prevent the items in the storage space 4 from leaving the storage space 4 from one side of the fixed mattress 11 in the first direction X due to the change in speed during the driving of the vehicle under the action of inertia.

[0054] Further, 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 disposed on a side of the bed assembly 100 away from the fixed mattress 11, and closes the storage space 4 together with the rear panel 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 items in the storage space 4 from leaving the storage space 4 due to inertia caused by speed changes during vehicle driving. At the same time, this arrangement can prevent 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 closed storage space 4, in some embodiments, the closing plate may be a multi-piece structure, and a corresponding guide rail is provided on the floor 210 to achieve translational movement of the closing plate, for example, along the second direction Y. Alternatively, the closing plate may also be pivotally connected to the floor 210 or other structures, so as to achieve opening and closing movement of the closing plate under the action of a force in the first direction X.

[0056] In an optional embodiment, the bed assembly 100 further includes a pivoting portion 6. The pivoting portion 6 includes a first connecting portion 61 and a second connecting portion 62 that are pivotally connected. The first connecting 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 connecting portion 62 is connected to the rear panel of the vehicle. Figure 1 As shown, by setting the pivoting part 6, the support part 2 and the mattress part 1 can be pivoted with the second connecting part 62 under the action of the first connecting part 61, that is, pivoted with the rear panel. Then, in this embodiment, the connection relationship between the base 3 and the support part 2 is abutting connection relationship, and there is no fixed connection relationship.

[0057] In this way, the support part 2 and the mattress part 1 can be pivoted away from the base 3 to expose the storage space 4; or they can be pivoted toward the base 3 to close the storage space 4. This arrangement does not require adding a guide rail or other structure in the vehicle to enable the closing plate to move to expose the storage space 4. At the same time, the pivoting and opening of the first connecting part 61 and the second connecting part 62 requires the application of a force away from the floor 210 in the height direction Z, and when the vehicle is hit by an external force, the direction of the force is usually toward the first direction X or the second direction Y. Therefore, this embodiment can, to a certain extent, prevent the items in the storage space 4 from leaving the storage space 4 when the vehicle is hit by an external force, thereby improving the storage safety of the items.

[0058] It should be noted that in the embodiment where the bed assembly 100 includes the pivoting 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 the needs of 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 an air support portion 7. The air support portion 7 includes a first end 71 connected to the base 3 and a second end 72 connected to the support portion 2. The air support portion 7 is used 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 air support portion 7 applies a force from the first end 71 toward the second end 72 to the support portion 2, thereby assisting the occupant to push the mattress portion 1 and the support portion 2 away from the base 3. When the occupant needs to cover the mattress portion 1 and the support portion 2, the air support portion 7 still applies a force from the first end 71 toward the second end 72 to the support portion 2, thereby causing the mattress portion 1 and the support portion 2 to slowly approach the base 3, thereby avoiding abnormal noise caused by the rapid covering of the mattress portion 1 and the support portion 2 when the occupant is insufficient in strength, or even causing pinching or bruising to the occupant. It can be seen that the provision of the air support portion 7 is conducive to improving the safety of the bed assembly 100 when pivoting and opening and closing, as well as the ease of operation.

[0060] The bed assembly 100 may be connected to the vehicle only by the base 3, or in an embodiment with a pivot 6, only by the base 3 and the rear panel. Figures 2 to 4 As shown, in some embodiments, the vehicle includes a side panel 220 and a first supporting portion 230 disposed 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, reduce the requirements for the structural strength of the base 3, and further improve 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 disposed at the end portion of the fixed mattress 11 in the second direction Y, and it is not necessary 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 disposed only at 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 provided with a support frame 231 connected to the floor 210 and arranged in the side panel 220. The first support portion 230 is arranged at one end of the support frame 231 away from the floor 210. The support frame 231 is connected to the first support portion 230, and can bear the force in the height direction Z applied by the weight of the bed assembly 100 to the side panel 220, thereby avoiding deformation of the side panel 220 and improving the stability of the structure.

[0062] Since the side panels 220 are usually curved structures, it is difficult for the fixed mattress 11 to completely fill the gap between it and the side panels 220. The gap easily causes small and broken items placed on the bed assembly 100 by the occupant to fall in. Therefore, in some embodiments, the mattress portion 1 also includes a deformable caulking pad 13. The caulking pad 13 is arranged between the fixed mattress 11 and the side panels 220, and due to its deformable characteristics, it can be deformed according 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 and rubber. At the same time, there is no fixed connection between the caulking pad 13 and the fixed mattress 11. In other words, the occupant can take the caulking pad 13 out of the gap according to the use requirements. The setting of the caulking pad 13 can not only prevent items from falling into the gap between the side panels 220 and the fixed mattress 11, but also can further expand the lying area of ​​the mattress portion 1 in the second direction Y, which is conducive to improving the utilization of space.

[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 caulking 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, so as to fill the gap between the deformable mattress 12 and the side panels 220 and increase 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 contracted state, the apertures of the through holes 12 change. 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 an unfolded state. By configuring in this way, the deformable mattress 12 can be configured as a mattress such as a sponge pad, a rubber pad, etc. Compared with an inflatable pad, a mesh pad, etc., the deformable mattress 12 of this embodiment can further improve the lying comfort of the deformable mattress 12, thereby meeting the rest needs of the occupant. At the same time, the processing of the through hole 12 is simple, which reduces the processing cost of the deformable mattress 12.

[0065] The present application does not limit the number and diameter of the through holes 12. As the number of through holes 12 increases or the diameter of the through holes 12 increases, the deformability of the deformable mattress 12 increases. As the number of through holes 12 decreases or the diameter of the through holes decreases, the support of the deformable mattress 12 for the human body increases. Those skilled in the art can determine the required degree of deformation of the deformable mattress 12 based on the space in the vehicle cabin, and then select the number and diameter of the through holes 12. At the same time, 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 be 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 unfolded 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 unfolded state, and avoid the bending moment of the bed assembly 100 at the position of the fixed mattress 11 caused by gravity when the occupant lies or sits on the end of the deformable mattress 12 away from the fixed mattress 11, causing damage to the bed assembly 100. At the same time, the second supporting portion 240 is disposed on the side panel 220, and when the bed assembly 100 is in the retracted state, the second supporting portion 240 will not excessively occupy the space in the vehicle cabin.

[0068] In order to realize 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 against 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 increase the service life of the base 3 and the support portion 2 and reduce the noise generated by friction during the 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 use experience.

[0069] Compared to the embodiment in which the guide rail is provided on the side panel 220 to realize the movement of the support part 2, the slide rail part 5 is provided on the base 3, so that the bed assembly 100 can be assembled as a whole before being assembled on the vehicle, without first assembling part of the guide rail on the vehicle and then assembling the guide rail corresponding to the bed assembly 100 on the guide rail of the vehicle. In addition, compared to the side panel 220 with multiple curved surfaces, the base 3 and the support part 2 can be more conveniently provided as a flat structure as the installation surface of the slide rail part 5.

[0070] refer to Figure 5 and Figure 6 In some embodiments, the slide rail portion 5 includes a locking structure 53 and a slide rail handle 54 that are fixedly connected. 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 unfolded state, the locking structure 53 is located in the first slot 511. When the bed assembly 100 is in the retracted 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 so that the locking structure 53 is pivoted away from the first slot 511 or away from the second slot 512 through the slide rail handle 54. By providing the slide rail handle 54 and the locking structure 53, the slide rail portion 5 can be effectively locked to avoid the noise caused by the back-and-forth relative movement of the first sliding unit 51 and the second sliding unit 52 in the first direction X due to the speed during the vehicle driving process. In addition, the provision of the slide rail handle 54 provides the occupant with a force application point for applying force to the bed assembly 100, so that the occupant can push or pull the second sliding unit 52 more easily.

[0071] When the occupant needs to switch the bed assembly 100 from the retracted state to the expanded state, the occupant 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 achieving 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] Indeed, 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 and avoid unexpected relative movement between the first sliding unit 51 and the second sliding unit 52 during vehicle driving.

[0074] Further, 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 arrangement of the first slot 511 and the second slot 512 can be regarded as two gears, namely, the unfolding gear and the retracting gear. By arranging a plurality of intermediate slots 513, the second sliding unit 52 and the first sliding unit 51 can be fixed at different relative positions, so that the deformable mattress 12 can be maintained at a plurality of positions between the first distance D1 and the second distance D2. In this way, the bed assembly 100 allows the occupant to select the unfolding size of the deformable mattress 12 according to the actual lying area required. At the same time, this arrangement also allows the bed assembly 100 to be unfolded in a limited space when the cabin is occupied by items in some cases and the bed assembly 100 cannot be switched to the unfolded state, thereby improving the applicability of the bed assembly 100 in different situations.

[0075] like Figure 4 and Figure 5 As shown, the number of bases 3 includes two. 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 embodiments 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 illustrated embodiment should be taken as an example rather than 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 parts 5, or the rail handles 54 may be arranged on the right side and the fixed handle 92 may be arranged on the left side. The present application does not limit this.

[0077] In some embodiments, the number of the support part 2 may be only one. The support part 2 can move with the deformable mattress 12 and is in a relative moving relationship with the fixed mattress 11. Alternatively, the support part 2 is fixedly connected to the fixed mattress 11, while the deformable mattress 12 and the support part 2 are in a relative moving relationship.

[0078] Or, if 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 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 fixedly connected to one side of the deformable mattress 12 in the first direction X. By such an arrangement, the deformable mattress 12 and the fixed mattress 11 have corresponding support portions 2 under them to achieve rigid support, which is beneficial to improving the structural stability of the mattress portion 1 and the human body support effect.

[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. By such a configuration, the second sliding unit 52 drives the second support plate 22 to move without affecting the first support plate 21. Therefore, the configuration of this embodiment is conducive to further reducing the influence of the deformable mattress 12 on the fixed mattress 11 during the movement process.

[0080] Further, the first sliding unit 51 may be fixedly connected to the base 3, or may be fixedly connected to the first support plate 21. In the embodiment where 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 to move 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 to approach the base 3 and finally 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 part 2. In this way, the gas strut 7 can assist the support part 2 in pivoting.

[0082] In order 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 avoidance slide groove 221 for avoiding the second sliding unit 52. The avoidance slide groove 221 extends in a direction away from the fixed mattress 11 along the first direction X at one end of the second support plate 22 facing the fixed mattress 11. By such a configuration, the slide rail portion 5 can be at least partially accommodated in the avoidance slide groove 221, thereby reducing the size occupied by the support portion 2 and the slide rail portion 5 in the height direction Z.

[0083] In the embodiment where the support portion 2 includes a first support plate 21 and a second support plate 22, optionally, when the bed assembly 100 is in the expanded state and the contracted state, the first support plate 21 and the second support plate 22 at least partially overlap in the first direction X. In this way, when the deformable mattress 12 moves so that the bed assembly 100 switches to the expanded state, the first support portion 2 and the second support portion 2 can still fully support the fixed mattress 11 and the deformable mattress 12. Compared with the solution in which there is a gap between the first support plate 21 and the second support plate 22 in the first direction X when the bed assembly 100 is in the expanded state, this embodiment can further ensure the rigid support of the support portion 2 to the mattress portion 1, thereby improving the human body support comfort that the bed assembly 100 can bring.

[0084] exist Figure 4 In the illustrated embodiment, the first support plate 21 is disposed closer to the mattress portion 1 than the second support plate 22 in the height direction Z. Therefore, in order to facilitate the assembly of the bed assembly 100, the first support plate 21 is provided with an escape groove 211. The escape groove 211 can expose the second support plate 22, thereby facilitating the assembly and connection of the second support plate 22. In the embodiment where the second support plate 22 includes the escape groove 221, the escape groove 211 and the escape groove 221 can be directly connected in the height direction Z, thereby exposing the slide rail portion 5 or the base 3, which is convenient for installation.

[0085] In an optional embodiment, the bed assembly 100 further includes fabric and a rolling portion 8. The rolling portion 8 is disposed on a side of the deformable mattress 12 away from the fixed mattress 11. One end of the fabric is connected to a side of the fixed mattress 11 away from the deformable mattress 12, and the other end 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 shielding 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 of the bed assembly 100 when it is in the expanded state. However, when the bed assembly 100 is switched to the contracted state, there will be excess fabric. Therefore, the setting 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 may 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 may also be electric, and the retraction of the fabric may be achieved by rotating the motor. Alternatively, the retracting portion 8 may 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 stored 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 stored state to the deployed state, the occupant needs to overcome the force applied by the elastic member to achieve the state switching of the bed assembly 100.

[0087] In order to prevent the retracted portion 8 from affecting the comfort of the occupant when lying down, Figure 4 As shown, in one embodiment, the deformable mattress 12 includes a storage groove 122. The storage groove 122 is arranged on the side of the deformable mattress 12 facing the support part 2 and the side away from the fixed mattress 11. The retracting portion 8 is arranged in the storage groove 122. By such an arrangement, the retracting portion 8 can be hidden on the side of the deformable mattress 12 facing the base 3. At the same time, the storage groove 122 is also arranged on the side of the deformable mattress 12 away from the fixed mattress 11. This arrangement can minimize the coverage area of ​​the fabric on the side of the mattress part 1 facing the support part 2, which is conducive to reducing the cost of the fabric.

[0088] The connection between the fabric and the fixed mattress 11 can be a detachable connection. At the same time, the connection between the fabric and the retracting portion 8 can also be a detachable connection. In this way, the fabric can be removed from the bed assembly 100, so that the occupant can regularly clean the fabric, which is conducive to 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 sharp structure inside the retractor 8 from causing harm to the human body.
