Description

Technical Field

[0001] The present invention relates to the technical field related to furniture packaging, and in particular to a packaging device and a packaging method for an electric unit bed. Background Art

[0002] In modern home life, electric unit beds are popular among consumers for their adjustable bed angles, convenient operation methods and comfortable sleeping experience. However, the structure of electric unit beds is relatively complex, usually consisting of multiple independent but interrelated parts, including the bed board part, bed board support part, bed board drive part and connecting parts part. These parts need to be properly packaged during transportation and storage to prevent damage and ensure safe delivery to consumers.

[0003] Traditional packaging methods often package electric unit beds as a whole, which not only makes the packaging bulky and difficult to fit into standard shipping dimensions, but also increases transportation costs and difficulties. In addition, overall packaging may also lead to damage caused by vibration or impact during transportation, further increasing after-sales costs and user dissatisfaction. Summary of the invention

[0004] In order to overcome at least one of the defects of the prior art, the present invention provides a packaging device and a packaging method for an electric unit bed, which can solve the problem of oversized packaging size, and can greatly reduce the shipping size, transportation cost and transportation difficulty through modular design and accurate calculation of packaging size.

[0005] The technical solution adopted by the present invention to solve the problem is:

[0006] A packaging device for an electric unit bed comprises: an electric bed, wherein the electric bed comprises a bed board portion, a bed board support portion, a bed board drive portion and a connecting parts portion which can be disassembled into independent individuals, wherein the bed board portion comprises at least a calf section bed board, a thigh section bed board, a seat section bed board and a back section bed board; the bed board support portion comprises at least a calf support member, a thigh support member, a seat support member and a back support member, wherein the bed board drive portion comprises at least a back drive member for driving the back support member and a leg drive member for driving the calf support member or the thigh support member; a packaging bottom shell, wherein the packaging bottom shell has a storage slot for accommodating the bed board portion, the bed board support portion, the bed board drive portion and the bed frame portion, wherein the small The maximum length of the leg section bed board, thigh section bed board, seat section bed board and back section bed board is X1, and the maximum height is H1. The maximum length of the calf support, thigh support, seat support and back support is X2, and the maximum thickness is H2. The motor axis in the bed board driving part is defined as the height direction, and the maximum height of the back driving part and the leg driving part is H3. Then the length M, width N and depth L of the storage groove satisfy: M≥X1; N≥X2; X1≥X2; 2·(H1+H2)+H3≥L>2·H1+H3; a packaging cover body, wherein the packaging cover body has a wrapping groove for accommodating at least part of the packaging bottom shell, so as to wrap and cover the storage groove of the packaging bottom shell.

[0007] By adopting the above solution, the electric bed can be disassembled into multiple modules. According to the size of each component, the minimum length M, minimum width N and minimum depth L of the storage slot of the packaging bottom shell can be accurately calculated to ensure that the size of the storage slot meets the accommodation requirements of all components while avoiding unnecessary waste of space; modular design and precisely calculated packaging size greatly reduce the volume of a single package, making it easier to adapt to standard transportation sizes. Small-volume packaging reduces the occupancy of transportation space, reduces the difficulty of loading and unloading and transportation, and reduces transportation costs and postage.

[0008] Furthermore, the calf section bed board, thigh section bed board, seat section bed board and back section bed board each include at least two minimum bed board units of consistent specifications and sizes, the width of the minimum bed board unit is Y1, and the height is Z1, the width of the back driving component and the leg driving component is Y3, Y3≤Y1×3, and the number S of the minimum bed board units in the storage slot satisfies: N÷Y1×3>S≥N÷Y1×2.

[0009] By adopting the above solution, the minimum unit of the bed board can be set up in two to three layers, and the two layers are arranged at intervals to cover the middle layer, so that the back driving parts and the leg driving parts can be inserted into the middle layer. The back driving parts and the leg driving parts are within three times the width Y3, so the back driving parts and the leg driving parts can pass through the middle layer smoothly, saving the longitudinal space of the packaging while meeting the storage needs of the minimum unit of the bed board.

[0010] Furthermore, the minimum unit of the bed board is divided into at least two layers along the storage groove, wherein at least two layers are staggered with the back driving member and the leg driving member in the depth direction of the storage groove.

[0011] By adopting the above solution, the design of the smallest unit of the bed board being layered and staggered along the storage slot brings the advantages of optimized space utilization and convenient transportation and storage.

[0012] Furthermore, the minimum unit of the bed board is provided with three layers, namely the first bed board layer, the second bed board layer and the third bed board layer, the minimum unit of the back section bed board is located in the first bed board layer, the minimum unit of the thigh section bed board and the seat section bed board are located in the third bed board layer, the minimum unit of the calf section bed board and the driving part are located in the second bed board layer, the empty space between the first bed board layer and the second bed board layer forms a first storage layer, the empty space between the second bed board layer and the third bed board layer forms a second storage layer, and the bed board support part and the connecting parts part are located in the first storage layer and / or the second storage layer.

[0013] By adopting the above scheme, the layered design makes the bed board components more orderly and convenient during loading and unloading, and makes the positional relationship between the various components clearer. Users can more easily identify each component during assembly and assemble them in the correct order, reducing the complexity and time cost of operation. The optimized packaging size makes the electric unit bed more space-saving during storage and reduces storage costs.

[0014] Furthermore, a first extension layer is arranged above the first bed board layer, and a second extension layer is arranged below the third bed board layer, and the bed board supporting part is placed on the first storage layer and the second storage layer, or the bed board supporting part is placed on the first extension layer and the second extension layer, and the connecting parts part is placed on the first storage layer and the second storage layer.

[0015] By adopting the above solution, the addition of the first expansion layer and the second expansion layer provides additional storage space for the bed support part, the connecting parts part and other possible accessories, which helps to further reduce the space waste in the bottom shell of the package and improve the overall space utilization.

[0016] Furthermore, the calf section bed board includes at least two minimum bed board units and driven connecting rods vertically connected to the minimum bed board units, the driven connecting rods are provided with at least two groups and are symmetrically arranged under the calf section bed board, the height of the driven connecting rods is Z2, Z2≥X2, and the maximum height H3 of the back driving component and the leg driving component satisfies: Z2+Z1+2·X2<H3≤Z2+2·Z1+2·X2.

[0017] By adopting the above scheme, the setting of the driven connecting rod, especially the design of at least two groups and symmetrically, provides additional support for the calf section bed board. When the leg driving member of the electric bed controls the lifting of the thigh section bed board, the calf section bed board can be lifted accordingly to achieve a linkage effect. At the same time, the height relationship between H3 and the linkage rod is limited so that the driven rod can be staggered and set next to the back driving member and the leg driving member to complete the storage without occupying the longitudinal space.

[0018] Furthermore, the gap between two adjacent minimum units of the calf section bed board is Q, Q>Y1; the back driving component and the leg driving component are both push rod motors, and the push rod motor includes a push rod, a motor and a connecting seat, and the widths of the push rod, the motor and the connecting seat are A, B and C respectively, and A<B<C, C≤Q.

[0019] By adopting the above scheme, the gap Q between the two adjacent minimum units of the calf section bed board is greater than the width Y1 of the minimum unit of the bed board, and the maximum width C of the motor is less than or equal to the gap Q, so that the push rod motor can smoothly pass through the gap Q, which is conducive to storage.

[0020] Furthermore, the back driving component and the leg driving component are both arranged between the two bed boards of the calf section bed board, and the heights of the first storage layer and the second storage layer are H6 and H7 respectively, H3 / 2>H6≥H2, H3 / 2>H7≥H2, H3≥H6+H7+Z1+Z2.

[0021] By adopting the above solution, the driving part does not occupy additional external space, but is cleverly embedded in the bed board structure. This helps to optimize the overall space layout and improve space utilization. The height of the first storage layer and the second storage layer is neither too high nor too low, but is coordinated with the height of the driving part and the overall structure. Such a design not only ensures the practicality of the storage layer, but also avoids space waste.

[0022] Furthermore, the thigh support member includes at least two thigh bed board support rods for providing support for the thigh section bed board and a thigh rotating frame for connecting the leg driving member with the thigh bed board support rods, the back support member includes at least two back bed board support rods for providing support for the back section bed board and a back rotating frame for connecting the back driving member with the back bed board support rods, the thigh bed board support rods and the back bed board support rods are respectively placed on the first storage layer and the second storage layer, and the thigh rotating frame and the back rotating frame are respectively placed on the first extension layer and the second extension layer.

[0023] By adopting the above scheme, in the electric bed, the thigh rotating frame and the back rotating frame serve as bridges connecting the leg driving components and the back driving components with the bed board support rods. Their existence enables the driving components to smoothly drive the bed board to move. After disassembly, they are placed on the first expansion layer and the second expansion layer respectively, and can provide good support effect for the packaging cover on the first expansion layer and the packaging shell under the second expansion layer in the storage cavity to avoid collapse, while realizing effective use of space and compactness of structure.

[0024] A packaging method for an electric unit bed, which is applied to a packaging device for an electric unit bed, comprises the following packaging steps: S1, disassembling the electric bed into a bed board part, a bed board support part, a bed board drive part and a connecting parts part, wherein the bed board part is disassembled into four groups of a calf section bed board, a thigh section bed board, a seat section bed board and a back section bed board, and the bed board support part is disassembled into a calf support part, a thigh support part, a seat support part and a back support part; S2, bringing the minimum bed board units in the seat section bed board and the thigh section bed board closer to each other and arranging them linearly to form a single layer of a first bed board layer for standby use; bringing the minimum bed board units in the back section bed board closer to each other and arranging them linearly to form a single layer of a third bed board layer for standby use; keeping the calf section bed board connected to a driven connecting rod, and passing the disassembled back drive part and leg drive part through the minimum bed board units of the calf section bed board to form a second bed board layer located between the first bed board layer and the second bed board layer for standby use, and making the storage slot area of ​​the packaging bottom shell according to the largest area among the three bed board layers. The storage groove is sufficient to hold any layer; S3, the storage groove depth of the packaging bottom shell is made according to the stacking height of the first bed board layer, the second bed board layer and the third bed board layer, and the bed board support part and the connecting parts are placed on both sides of the second bed board layer to avoid the back drive member and the leg drive member; or, any two of the calf support member, the thigh support member, the seat support member and the back support member are separately formed into the first extension layer and the second extension layer, and the first extension layer and the second extension layer are placed above the first bed board layer and below the point bed board layer respectively, then the storage groove depth of the packaging bottom shell is made according to the stacking height of the first extension layer, the second extension layer, the first bed board layer, the second bed board layer and the third bed board layer, and the remaining bed board support parts and connecting parts are placed on both sides of the second bed board layer to avoid the back drive member and the leg drive member; S4, the filling member is made according to the storage cavity and the position of the parts of each layer, and the filling member is provided with an avoidance groove to avoid and fix the parts of each layer, and finally a packaging cover body that can cover the storage groove of the packaging bottom shell is made

[0025] By adopting the above scheme, the electric bed is divided into a bed board part, a bed board support part, a bed board drive part and a connecting parts part, and the bed board part is further subdivided into a calf section, a thigh section, a seat section and a back section, so that the disassembly and assembly process is more efficient and orderly, the operation process is simplified and the difficulty is reduced; by forming a first bed board layer, a second bed board layer and a third bed board layer, and determining the depth of the storage groove by judging the superposition height of the bed board layer height, the efficient use of space is achieved. This layered design not only reduces the occupied space, but also makes the overall structure more compact; placing fillers between each layer of bed boards not only maintains the relative stability of the bed board layer, but also plays a buffering and protective role. This helps to reduce the risk of damage to the bed board and its related components during transportation and storage. When placing the bed board support part and the connecting parts part, special attention is paid to avoiding the back drive and leg drive to avoid interference and damage between components.

[0026] In summary, the packaging device and packaging method of an electric unit bed provided by the present invention have the following technical effects:

[0027] 1. Through modular design and accurate calculation of the length, width and depth of the storage slots in the bottom shell of the packaging, it is ensured that the various components of the electric unit bed can be properly accommodated while avoiding unnecessary waste of space. This accurate calculation not only improves the compactness of the packaging, but also significantly reduces the volume of the packaging. Due to the reduction in packaging volume, the space occupied by the electric unit bed during transportation is also reduced accordingly, thereby reducing transportation costs. In addition, the small volume packaging also makes the loading and unloading and transportation processes more convenient, further improving transportation efficiency;

[0028] 2. Disassembling the electric unit bed into multiple independent modules for packaging not only simplifies the packaging process but also improves packaging efficiency. At the same time, the modular design also enables the various components to support and protect each other during transportation, reducing the risk of damage caused by vibration or impact;

[0029] 3. The modular and layered design makes it more convenient and quick for users to install and disassemble the electric unit bed, greatly reducing the user's operating difficulty and time cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] 1 Embodiment of the present invention 1 See Figure 1-Figure 7As shown, a packaging device for an electric unit bed is disclosed, comprising an electric bed 1, a packaging bottom shell 2 and a packaging cover 3, wherein the electric bed 1 comprises a bed board portion 11, a bed board support portion 12, a bed board drive portion 13 and a connecting part portion 14 which can be disassembled into an independent individual, wherein the bed board portion 11 comprises at least a calf section bed board 111, a thigh section bed board 112, a seat section bed board 113 and a back section bed board 114 along the length direction of the electric bed 1, and the bed board support portion 12 comprises at least a calf support member 121, a thigh support member 122, a seat support member 123 and a back support member The bed board driving part 13 at least includes a back driving part 131 for driving the back support part 124, and a leg driving part 132 for driving the calf support part 121 or the thigh support part 122. The packaging bottom shell 2 has a storage slot 21 for accommodating the bed board part 11, the bed board support part 12, the bed board driving part 13 and the bed frame part. The maximum length of the calf section bed board 111, the thigh section bed board 112, the seat section bed board 113 and the back section bed board 114 is X1, and the maximum height is H1, wherein X1 is the maximum length of the calf section bed board 111, the thigh section bed board 112, the seat section bed board 113 and the back section bed board 114. 112, the maximum value of the projection length of the seat section bed board 113 and the back section bed board 114 in the width direction of the electric bed 1; the maximum length of the calf support 121, the thigh support 122, the seat support 123 and the back support 124 is X2, and the maximum thickness is H2, wherein X2 is the maximum value of the projection length of the calf support 121, the thigh support 122, the seat support 123 and the back support 124 in the length direction of the electric bed 1, and the motor axis in the bed board driving part 13 is defined as the height direction, and the back driving part 131 and the The maximum height of the leg driving member 132 is H3, and the length M, width N and depth L of the storage slot 21 satisfy: M≥X1; N≥X2; X1≥X2; Since the bed plate part 11 is divided into at least four parts, the length of X2 is set to not more than one-fourth of the length of the electric bed, and the width of the electric bed 1 determines the length of the storage slot 21, so the volume can be reduced by two to four times after packaging, and X1≥X2 is limited. In order to avoid the electric bed being too narrow, the height is limited to 2·(H1+H2)+H3≥L>2·H1+H3, which can effectively avoid the inability to put in all parts. The packaging cover 3 has a wrapping slot 31 that accommodates at least part of the packaging bottom shell 2, so as to wrap and cover the storage slot 21 of the packaging bottom shell 2. Since the length and width of the storage slot are controlled, the horizontal space occupied by the folding bed can be reduced by two to four times; and the height restriction of the storage slot 21 greatly reduces the height while ensuring that all parts are stored.With this arrangement, the electric bed 1 can be disassembled into multiple modules. According to the maximum length and maximum height of each component, the length M, width N and depth L of the storage slot 21 of the packaging bottom shell 2 can be accurately calculated to ensure that the size of the storage slot 21 meets the accommodation requirements of all components while avoiding unnecessary waste of space; the modular design and accurately calculated packaging size greatly reduce the volume of a single package, making it easier to adapt to standard transportation sizes, and small-volume packaging reduces the occupancy of transportation space, reduces the difficulty of loading and unloading and transportation, and reduces transportation costs and postage.

[0043] In some specific embodiments, the calf section bed board 111, the thigh section bed board 112, the seat section bed board 113 and the back section bed board 114 each include at least two bed board minimum units 115 of the same size, the width of the bed board minimum unit 115 is Y1, the height is Z1, the width of the back driving member 131 and the leg driving member 132 is Y3, Y3≤Y1×3, and the number S of the bed board minimum units 115 in the storage slot 21 satisfies: N÷Y1×3>S≥N÷Y1×2. The bed board minimum unit 115 is divided into at least two layers along the storage slot 21, wherein at least two layers are staggered with the back driving member 131 and the leg driving member 132 in the depth direction of the storage slot 21. The minimum unit 115 of the bed board can be arranged in two to three layers, and the two layers are arranged at intervals to cover the middle layer, so that the back driving component 131 and the leg driving component 132 can be inserted into the middle layer. The back driving component 131 and the leg driving component 132 are within three times the width Y3, so that the back driving component 131 and the leg driving component 132 can smoothly pass through the middle layer, saving the longitudinal space of the packaging while meeting the storage needs of the minimum unit 115 of the bed board.

[0044] It should be noted that, in this embodiment, X1 is the length of the minimum unit 115 of the bed board, the length direction of the minimum unit 115 of the bed board is the width direction of the electric bed 1, and X2 is the maximum length of the calf support 121, the thigh support 122, the seat support 123 and the back support 124. When the calf support 121, the thigh support 122, the seat support 123 and the back support 124 are non-rod-shaped structures, the length of X2 refers to the maximum length of the calf support 121, the thigh support 122, the seat support 123 and the back support 124 in the length direction of the electric bed. The vertical placement relationship between the bed board part 11 and the bed board support part 12 can be maintained during storage, which is convenient for disassembly and assembly.

[0045] Preferably, the bed board minimum unit 115 is provided with three layers, namely the first bed board layer 211, the second bed board layer 212 and the third bed board layer 213, the bed board minimum unit 115 of the back section bed board 114 is located in the first bed board layer 211, the bed board minimum unit 115 of the thigh section bed board 112 and the seat section bed board 113 are located in the third bed board layer 213, the bed board minimum unit 115 and the driving part of the calf section bed board 111 are located in the second bed board layer 212, the empty space between the first bed board layer 211 and the second bed board layer 212 forms a first storage layer 214, the empty space between the second bed board layer 212 and the third bed board layer 213 forms a second storage layer 215, and the bed board support part 12 and the connecting part part 14 are located in the first storage layer 214 and / or the second storage layer 215.

[0046] Since the calf section bed board 111, the thigh section bed board 112, the seat section bed board 113 and the back section bed board 114 each include at least two minimum bed board units 115, and the minimum bed board units 115 required for the back are usually twice that of other parts, taking each section of the bed board as an example with two minimum bed board units 115, there are a total of ten minimum bed board units 115. In order to enable the calf section bed board 111, the thigh section bed board 112, the seat section bed board 113 and the back section bed board 114 to be stacked in three layers, since it is necessary to design one of the bed boards in the storage slot 21 to be able to drive the back drive 131 and the leg drive 132, the number of bed boards in the cover layer needs to be at least two less than the number of bed boards in other layers, so the number of minimum bed board units 115 in the three layers is four, two and four respectively. In this way, the width of the storage slot 21 can be minimized. In the present embodiment 1, three minimum bed board units 115 are provided for the calf section bed board 111, three minimum bed board units 115 are provided for the thigh section bed board 112, three minimum bed board units 115 are provided for the seat section bed board 113, and six minimum bed board units 115 are provided for the back section bed board 114. Therefore, after disassembly, the number of minimum bed board units 115 is fifteen. In order to reserve storage positions for the back driving member 131 and the leg driving member 132 in one of the three-layer bed boards, the number of minimum bed board units 115 of the three-layer bed boards is six, three, and six, respectively. In order to avoid the back support member 124 under the back section bed board 114 being designed in sections, it is divided into two sections in the present embodiment, so as to ensure that the size is not much different from that of the other support members. Specifically, the length difference between the support members is at most 1.5 times of their own length, so as to ensure that the width of the storage slot 21 meets the requirement of being less than or equal to one quarter of the length of the electric bed 1.

[0047] It should be noted that, since the size of the frame cannot be reduced, the packaging device does not include the frame for storing the electric bed 1, and only includes the components within the frame.

[0048] In some embodiments, the calf section bed board 111 includes at least two minimum bed board units 115 and a driven connecting rod 1211 vertically connected to the minimum bed board units 115. The driven connecting rod 1211 is provided in at least two groups and is symmetrically arranged below the calf section bed board 111. The height of the driven connecting rod 1211 is Z2, Z2≥X2, and the maximum height H3 of the back driving member 131 and the leg driving member 132 satisfies: Z2+Z1+2·X2<H3≤Z2+2·Z1+2·X2, where Z1+Z2=H1. The above formula can limit the height range of the driven connecting rod 1211. In this embodiment 1, the calf section bed board 111 includes three minimum bed board units 115, and the driven connecting rod 1211 is provided in two groups.

[0049] Preferably, in order to facilitate the placement of the driving member and the leg driving member 132, the minimum bed board unit 115 of the calf section bed board 111 and the calf support member 121 are not disassembled when the electric bed 1 is disassembled. Optionally, these parts can be fixed, such as by welding, so that the length and width of the storage groove 21 can be made with reference to the length and width of the calf section bed board 111.

[0050] It should be noted that the gap between two adjacent bed board minimum units 115 in the calf section bed board 111 is Q, Q>Y1, so that the number of bed board minimum units 115 in other layers can be more than twice the number of the layer where the calf section bed board 111 is located; preferably, the back driving member 131 and the leg driving member 132 are both push rod motors, and the push rod motor includes a push rod, a motor and a connecting seat. The motor is vertically connected to the push rod through the connecting seat, so that the motor axis is consistent with the height direction of the storage slot 21, and the push rod direction is placed along the length direction of the storage slot 21. At this time, the lengths of the push rod, the motor and the connecting seat in the width direction of the storage slot 21 are A, B and C respectively, and A<B<C, C≤Q. The gap Q between two adjacent bed board minimum units 115 in the calf section bed board 111 is greater than the width Y1 of the bed board minimum unit 115, and the maximum width C of the motor is less than or equal to the gap Q, so that the push rod motor can smoothly pass through the gap Q, which is conducive to storage. In other embodiments, the back driving member 131 and the leg driving member 132 can be replaced with other members that can be placed between two adjacent bed board minimum units 115 in the calf section bed board 111 .

[0051] Furthermore, the heights of the first storage layer 214 and the second storage layer 215 are H6 and H7, respectively, H3 / 2>H6≥H2, H3 / 2>H7≥H2, H3≥H6+H7+Z1+Z2, so that the remaining parts can be stacked on the first storage layer 214 and the second storage layer 215. This ensures that the drive component does not occupy additional external space, but is cleverly embedded in the second bed board layer 212, the first storage layer 214 and the second storage layer 215. This helps to optimize the overall space layout and improve space utilization. The heights of the first storage layer 214 and the second storage layer 215 are neither too high nor too low, but are coordinated with the height of the drive component and the overall structure. Such a design not only ensures the practicality of the storage layer, but also avoids space waste.

[0052] In some embodiments, before the electric bed 1 is disassembled, the thigh support 122, the seat support 123 and the back support 124 are all vertically connected below the minimum bed board unit 115. Specifically, the thigh support 122 includes at least two thigh bed board support rods 1221 for providing support for the thigh section bed board 112 and a thigh rotating frame 1222 for connecting the leg driving member 132 with the thigh bed board support rod 1221.

The back rotating frame 1242 of 1241 will cause chaotic storage of parts if all the parts are stacked in the first storage layer 214 and the second storage layer 215 due to the addition of the above-mentioned structure. For this purpose, a first expansion layer 216 is arranged above the first bed board layer 211, and a second expansion layer 217 is arranged below the third bed board layer 213. Optionally, the bed board supporting part 12 is placed on the first storage layer 214 and the second storage layer 215, or the bed board supporting part 12 is placed on the first expansion layer 216 and the second expansion layer 217, and the connecting part part 14 is placed on the first storage layer 214 and the second storage layer 215. In this embodiment 1, the thigh bed board support rod 1221 and the back bed board support rod 1241 are respectively placed on the first storage layer 214 and the second storage layer 215, and the thigh rotating frame 1222 and the back rotating frame 1242 are respectively placed on the first expansion layer 216 and the second expansion layer 217, which can provide good support effect for the packaging cover body 3 on the first expansion layer 216 and the packaging shell under the second expansion layer 217 in the storage cavity to avoid collapse, while realizing effective use of space and compactness of structure.

[0053] Preferably, in order to further provide stability and shock resistance of the parts in the storage slot 21, the storage slot 21 also includes a filling piece, and the filling piece is provided with an avoidance groove, and the avoidance groove is used to avoid the bed board part 11, the bed board support part 12, the bed board drive part 13 and the connecting part part 14, and the cross-sectional area of ​​the avoidance groove is less than or equal to the above parts, and can be clamped. The design of the filling piece and its avoidance groove reduces the collision between the bed board and its related parts and the inner wall of the storage slot 21 when moving or adjusting. This helps to reduce the risk of wear and damage of the parts and extend the service life of the product. The filling piece is usually made of soft or elastic materials, which can play a buffering role to a certain extent. When the bed board and its related parts are impacted by external forces, the filling piece can absorb part of the impact force, thereby protecting the parts from damage; the design of the filling piece and its avoidance groove makes it easier to position and align the bed board and its related parts during installation. This helps to simplify the installation process and reduce the difficulty and cost of installation. Optionally, the filling piece includes but is not limited to kraft paper, foam, sponge layer, etc.

[0054] In order to arrange a filling piece in the storage groove 21, in actual use, the length, width and height of the storage groove 21 are slightly larger than the parts inside. Preferably, the interval between the parts can be between 2mm-100mm to achieve the fixing and buffering effect.
