[0116] The embodiment provides a bed frame, as shown in FIG. 8, the bed frame includes a bed frame body 100b and a headboard, and the headboard is connected to the bed frame body 100b. The bed frame body 100b is used for supporting a mattress, and the bed frame body 100b may include side plates, a footboard and support plates.

[0117] In actual usage, a side of the headboard faces a wall, and the wall may provide a certain support force for the headboard arranged upright; another side of the headboard faces the bed frame body 100b, to facilitate the user to lean against it and improve comfort for the usage.

[0118] If the headboard is in an integral structure, the headboard may have a relatively large volume during transportation, resulting in that it is difficult to carry and disassemble the headboard. In view of this, the embodiment provides a headboard, as shown in FIG. 9 to FIG. 11, the headboard includes connection members 2b and multiple headboard frames 1b, adjacent headboard frames 1b are connected there-between by connection members 2b respectively, and the adjacent headboard frames 1b are rotatable relative to each other around their corresponding connection member 2b, such that two adjacent headboard frames 1b are switched between a folded state and an unfolded state.

[0119] The multiple headboard frames 1b are arranged along a width direction of the headboard frames 1b, that is, an arrangement direction of the multiple headboard frames 1b is the width direction of the headboard frames 1b. Exemplarily, two headboard frames 1b are provided, the two headboard frames 1b may have the same width or different widths, and in the embodiment, it is preferable that the two headboard frames 1b have the same width. The two adjacent headboard frames 1b are connected there-between by a connection member 2b, that is, the headboard frames are provided in a two-fold style; in some other embodiments, three headboard frames 1b are provided, and any two adjacent headboard frames 1b are connected there-between by the connection member 2b respectively, that is, the headboard frames are provided in a three-fold style; furthermore, the headboard frames may also be provided in other multi-fold styles.

[0120] The connection member 2b is a flexible belt. Since the flexible belt has a certain flexibility, it facilitates the two adjacent headboard frames 1b to rotate relative to each other, thereby improving convenience of operations.

[0121] Exemplarily, the flexible belt is a PP woven belt or a PA nylon belt, the PP woven belt may also be referred to as a braided belt made of polypropylene, and the PA nylon belt may also be referred to as polyamide. Preferably, material of the flexible belt is a PP woven belt, the PP woven belt has an advantage of cheap price. Of course, the material of the flexible belt may also select a PA nylon belt or a flexible belt-shaped material of other components.

[0122] Optionally, the connection member 2b is fixed to the headboard frames 1b by nailing or pasting thereto, which facilitates fixation and installation of the connection member 2b and has a relatively low safety cost.

[0123] When the unfolded state is required, side surfaces of the two adjacent headboard frames 1b facing the bed frame body 100b are rotated along a direction in which they go away from each other through the connection member 2b, sides of the headboard frames 1b away from the bed frame body 100b usually abut against a wall, sides of the headboard frames 1b close to the bed frame body 100b are connected by the connection member 2b, such that side surfaces of the headboard frames 1b close to the bed frame body 100b form a flat surface with each other, that is, a backrest surface for the user to lean against it may be formed into a flat surface, which has good comfort.

[0124] When the folded state is required, side surfaces of the headboard frames 1b away from the bed frame body 100b are separated from each other, and side surfaces of the two adjacent headboard frames 1b facing the bed frame body 100b are rotated along a direction in which they are close to each other through the connection member 2b, such that the two adjacent headboard frames 1b are folded to form a stacked structure, which facilitates carrying and transporting them subsequently.

[0125] The connection member 2b of the headboard is arranged at sides of the headboard frames 1b facing the bed frame body 100b.

[0126] In this way, there is a gap between side surfaces of the two adjacent headboard frames 1b away from the bed frame body 100b, which facilitates folding the two adjacent headboard frames 1b, that is, rear side parts of the headboard may be separated from each other in the folded state; there is no gap between side surfaces of the two adjacent headboard frames 1b facing the bed frame body 100b due to presence of the connection member 2b, that is, front side parts of the headboard may not be separated from each other no matter in the folded state or the unfolded state, which is equivalent to covering or blocking the gap between two adjacent bed frame bodies 100b by the connection member 2b in the unfolded state, such that there are good usage performance and beautiful appearance.

[0127] If there is a gap between the two adjacent headboard frames 1b in the unfolded state, not only the connection member 2b spans across the two adjacent headboard frames 1b, but also a portion of structures of the connection member 2b is located between the two adjacent headboard frames 1b. Since the connection member 2b is made of a relatively soft material, there may be a situation where the headboard frames 1b do not have enough support strength and easily fall down.

[0128] In view of this, as shown in FIG. 12, in the unfolded state, the two adjacent headboard frames 1b abut against each other, and a projection of the connection member 2b on a reference plane is located within projections of the two adjacent headboard frames 1b on the reference plane; the reference plane is a plane where contact surfaces between the headboard frames 1b and the connection member 2b are located, that is, the reference plane may also be a plane where side surfaces of the headboard frames 1b facing the bed frame body 100b are located.

[0129] In this way, the connection member 2b completely covers the two adjacent headboard frames 1b, there is no gap between the two adjacent headboard frames 1b in the unfolded state, sides of the two adjacent headboard frames 1b that are close to each other may abut against each other, and the two adjacent headboard frames 1b may support each other, thereby increasing support strength of the headboard frames 1b and reducing a risk of the headboard frames 1b falling down.

[0130] If a side surface of the headboard frame 1b facing a bed body is non-flat or provided with a concave-convex structure, side surfaces of the two adjacent headboard frames 1b facing a bed body cannot completely fit with each other or parallel to each other in the folded state, such that the headboard may form a V-shaped structure as a whole, resulting in that the two adjacent headboard frames 1b occupy a relatively large space when they are stacked and are easy to tilt.

[0131] In order to solve this problem, as shown in FIG. 13 to FIG. 15, for the headboard provided in the embodiment, in the unfolded state, the connection member 2b has a connection position 20b for the connection member to connect with at least one of the two adjacent headboard frames 1b, and an interval is provided between the connection position 20b and each of side edges of the two adjacent headboard frames 1b that are close to each other along an arrangement direction of multiple headboard frames 1b in the unfolded state.

[0132] Exemplarily, the connection positions 20b between the connection member 2b and the headboard frames 1b are not arranged along edges of the two adjacent headboard frames 1b abutting against each other in the unfolded state; instead, at the edges of the two adjacent headboard frames 1b abutting against each other, move along the arrangement direction of the multiple headboard frames 1b and toward a side where the two adjacent headboard frames 1b go away from each other, to form the connection positions 20b between the connection member 2b and the headboard frames 1b.

[0133] A clearance space is formed by the interval. In the folded state, non-flat or protruded parts of side surfaces of the headboard frames 1b facing the bed body may be avoided by the clearance space, such that side surfaces of the two adjacent headboard frames 1b facing the bed body are parallel to each other as much as possible, to reduce space occupied by the two adjacent headboard frames 1b when they are stacked, and also reduce a tilting risk.

[0134] Furthermore, in the folded state, there may be a certain movable space between the two adjacent headboard frames 1b with an action of the interval, the connection member 2b may be substantially rolled into an arc structure, and bending force may be dispersed at different positions of the connection member 2b, such that apparent crease may not appear in a middle portion of the connection member 2b.

[0135] Exemplarily, each of the headboard frames 1b is provided with a first edge 101b, a second edge 102b, a third edge 103b and a fourth edge 104b connected end to end, the first edge 101b and the second edge 102b are arranged opposite to each other and distributed along the arrangement direction of the multiple headboard frames 1b, the third edge 103b and the fourth edge 104b are arranged opposite to each other. In the unfolded state, the first edges 101b of two adjacent headboard frames 1b abut against each other, and an interval is provided between the connection position 20b between the connection member 2b and each of the headboard frames 1b and the first edge 101b corresponding to the connection member 2b.

[0136] In an embodiment, the connection member 2b may have a connection position 20b for the connection member to connect with one of the two adjacent headboard frames 1b. That is, one of the two adjacent headboard frames 1b may be connected to the connection member 2b through the connection position 20b, and another one of the two adjacent headboard frames 1b may be connected to the connection member 2b in other connection ways, to achieve a single-sided connection of the connection member 2b, such that there are good freedom and flexibility.

[0137] In an embodiment, the connection member 2b has a connection position 20b for the connection member to connect with each of the two adjacent headboard frames 1b. That is, the connection member 2b is connected to the two adjacent headboard frames 1b at two sides along the arrangement direction of the multiple headboard frames 1b respectively, to achieve a double-sided connection of the connection member 2b, achieve good connection consistency, save assembly time and reduce production cost.

[0138] In an embodiment, the connection member 2b is bent or folded along the connection position 20b, when the two adjacent headboard frames 1b are in the folded state.

[0139] Since the connection member 2b is fixed to the headboard frames 1b at the connection position 20b, the connection position 20b plays a role of a rotation shaft actually, such that the connection member 2b and the headboard frames 1b are rotatable relative to each other, while the connection member 2b and the headboard frames 1b may not be separated from each other completely. Furthermore, in this way, a position where the connection member 2b is bent or folded is not limited to a middle position of the connection member 2b, to avoid a situation where crease appears only at the middle position of the connection member 2b, thereby improving overall aesthetics in the unfolded state.

[0140] In an embodiment, as shown in FIG. 16, the interval provided between the connection position 20b and each of side edges of the two adjacent headboard frames 1b that are close to each other along the arrangement direction of the multiple headboard frames 1b in the unfolded state is d, here d ≥ 1 cm. With the interval d ≥ 1 cm, the connection member 2b obtains a movable space with a width of at least 1 cm in the folded state, thereby improving an avoidance effect.

[0141] Furthermore, 1.5 cm ≤ d ≤ 5 cm. For example, d may be 1.5 cm, 2 cm, 3 cm, 5 cm, etc.

[0142] If each of the headboard frames 1b is provided with a relatively large protruded part, the thicker the thickness of the protruded part, the larger the required avoidance space. The interval d is set between 1.5 cm and 5 cm, and the interval d is matched with the protruded part of each of the headboard frames 1b to the maximum extent, thereby improving flatness of the headboard and bed frame 1 in the folded state.

[0143] The connection member 2b has a width D along the arrangement direction of the multiple headboard frames 1b; for example, the flexible belt has a width of 10 mm to 10 mm, for example, the flexible belt may select to have a width of 8 cm.

[0144] It may be understood that the connection position 20b between the connection member 2b and each of the headboard frames 1b cannot be too close to a corresponding edge of the connection member 2b, since when the headboard frames 1b are switched between the unfolded state and the folded state, one of the headboard frames 1b may drive another one of the headboard frames 1b to swing through the connection member 2b due to heavy weights of the headboard frames 1b, inducing a situation where tearing appears between the connection member 2b and the headboard frames 1b. Along an arrangement direction of the two adjacent headboard frames, there is a certain distance between the connection position 20b between the connection member 2b and each of the headboard frames 1b and the corresponding edge of the connection member 2b, such that a certain margin of activity may be added.

[0145] Since the connection member 2b is located between the two adjacent headboard frames 1b, a transitional connection part between the headboard frames 1b and the connection member 2b may be seen from the front side of the headboard, which affects aesthetics. In view of this, the headboard further includes a first covering layer 3b (as shown in FIG. 12), the first covering layer 3b is arranged at sides of the headboard frames 1b facing the connection member 2b, and the first covering layer 3b covers outer sides of the two adjacent headboard frames 1b and the connection member 2b corresponding to the two adjacent headboard frames 1b respectively.

[0146] The entirety of the two adjacent headboard frames 1b and the connection member 2b between the two adjacent headboard frames 1b is covered by the first covering layer 3b, to hide a transitional connection part between the two adjacent headboard frames 1b and the connection member 2b, such that there is no gap at the connection between the two headboard frames 1b after assembly; in the unfolded state, the side of the headboard facing the bed frame body 100b is still in an integral structure, thereby achieving a beautiful appearance.

[0147] Furthermore, the first covering layer 3b also achieves the connection between the two adjacent headboard frames 1b, a connection effect between the two adjacent headboard frames 1b is improved with a combined action of the connection member 2b and the first covering layer 3b, and abrasion of the connection member 2b is reduced in a process of switching between the unfolded state and the folded state, thereby extending a service life of the connection member 2b.

[0148] Exemplarily, the first covering layer 3b may be a soft outer skin, and material of the soft outer skin may be a leather material, a cloth material, etc. The first covering layer 3b may be fixed to outer sides of the headboard frames 1b by nailing or pasting thereto, or may detachably cover outer sides of the headboard frames 11a. For example, the headboard frames 1b and the first covering layer 3b may be connected there-between by Velcro.

[0149] In an embodiment, the first covering layer 3b includes multiple covering parts (not shown in the figures), and the multiple covering parts cover outer sides of the multiple headboard frames 1b correspondingly, such that each of the headboard frames 1b may be completely covered and blocked by a covering part corresponding thereto, to avoid a situation where the headboard frames 1b are exposed, thereby achieving good aesthetics.

[0150] The first covering layer 3b further includes a connection part (not shown in the figures), the connection part is arranged between two adjacent covering parts from the multiple covering parts, and the adjacent headboard frames 1b are rotatable relative to each other around the connection part.

[0151] The gap between the two adjacent headboard frames 1b is hidden by the connection part of the first covering layer 3b, such that there is no gap between the two adjacent headboard frames 1b after assembly, when it is viewed from a front side facing the bed frame body 100b; in the unfolded state, the side of the headboard facing the bed frame body 100b is still in an integral structure, thereby achieving a beautiful appearance.

[0152] Furthermore, the connection part also achieves the connection between the two adjacent headboard frames 1b, and a connection effect between the two adjacent headboard frames 1b is improved. Furthermore, the connection part also provides a rotation center for the two adjacent headboard frames 1b, such that the two adjacent headboard frames 1b are rotatable relative to each other through the connection part, to achieve switching between the unfolded state and the folded state.

[0153] The covering parts and the connection part are in an integrally formed structure.

[0154] In this way, processes of processing the covering parts and the connection part separately and assembling and connecting the covering parts with the connection part are reduced, and production cost is saved. Furthermore, the first covering layer 3b in an integrally formed structure has good overall consistency and strong aesthetics.

[0155] In an embodiment, the connection part has a fixed position for the connection part to connect with at least one of the two adjacent headboard frames 1b, or the connection part has a fixed position for the connection part to connect with a covering part from the multiple covering parts corresponding to at least one of the two adjacent headboard frames 1b, and a distance is provided between the fixed position and each of side edges of the two adjacent headboard frames 1b that are close to each other along the arrangement direction of the multiple headboard frames 1b in the unfolded state.

[0156] It should be particularly noted that the fixed position may substantially coincide with the connection position 20b, then the distance is the same as the interval d at this time; of course, in some other embodiments, the fixed position may also coincide with the connection position 20b, then the distance may be greater than the interval d at this time, to achieve avoidance.

[0157] In an embodiment, as shown in FIG. 17, each of the headboard frames 1b is provided with an abutment part 12b at a side of each of the headboard frames 1b away from the connection member 2b, and the abutment parts 12b corresponding to the two adjacent headboard frames 1b abut against each other in the unfolded state. In this way, a contact area between the two adjacent headboard frames 1b is increased in the unfolded state, thereby improving abutment stability and support strength.

[0158] It may be understood that the two adjacent headboard frames 1b are in a split structure, then the abutment parts 12b corresponding to the two adjacent headboard frames 1b are also in a split structure, and an edge of each of the abutment parts 12b is flush with an edge of a corresponding one of the headboard frames 1b along a direction in which the two adjacent headboard frames 1b are close to each other. In the unfolded state, the two adjacent headboard frames 1b are located on the same horizontal line, and the abutment parts 12b corresponding to the two adjacent headboard frames 1b abut against each other, thereby effectively improving strength and support performance of the two adjacent headboard frames 1b at a position where they are arranged in sections.

[0159] The abutment part 12b may be arranged at any position of each of the headboard frames 1b along a height direction of the headboard frames 1b, or the abutment part 12b and an extension part 11b may be in an integrally formed structure, thereby reducing assembly processes of parts and saving production cost.

[0160] In an embodiment, as shown in FIG. 18, the headboard further includes a fixation member 4b, the fixation member 4b is arranged at a side of each of the headboard frames 1b away from the connection member 2b, and the two adjacent headboard frames 1b are detachably connected there-between by the fixation member 4b.

[0161] In the unfolded state, the two adjacent headboard frames 1b are connected there-between by the fixation member 4b, such that the adjacent headboard frames 1b do not rotate relative to each other during usage. In the folded state, the fixation member 4b is removed, the two adjacent headboard frames 1b are rotated along a direction in which they are close to each other and folded together, such that the headboard has a small package volume to facilitate transportation and storage.

[0162] Exemplarily, the fixation member 4b is connected to the headboard frames 1b by at least one of bolt connection or snap-fit connection, to facilitate installation and disassembly, and achieve more flexible switching between the unfolded state and the folded state.

[0163] Exemplarily, the fixation member 4b is at least one of a rod-shaped structure or a U-shaped buckle. When the fixation member 4b is a U-shaped buckle, an open end of the U-shaped buckle faces the headboard frames 1b and clamps edges of the two adjacent headboard frames 1b. When the fixation member 4b is in a rod-shaped structure, the fixation member 4b may span across the two adjacent headboard frames 1b, and the fixation member 4b is fixed to the two adjacent headboard frames 1b by bolts, such that the headboard may be stably used in the unfolded state.

[0164] Exemplarily, the fixation member 4b includes multiple fixation members, the multiple fixation members 4b are arranged along a height direction of the headboard frames 1b, and the height direction of the headboard frames 1b is perpendicular to the arrangement direction of the multiple headboard frames 1b.

[0165] For example, the fixation member 4b includes two fixation members, the two fixation members 4b are located above and below at sides of the headboard frames 1b away from the connection member 2b respectively, thereby improving a fixing effect between the two adjacent headboard frames 1b in the unfolded state.Fifth embodiment

[0166] The embodiment is similar to the fourth embodiment, and a difference of the embodiment compared to the fourth embodiment lies only in a specific structure of the first covering layer 3b.

[0167] As shown in FIG. 19 to FIG. 21, the first covering layer 3b provided in the embodiment includes an upholstery structure 5b. The upholstery structure 5b may be a foam, which may provide good support and cushion functions for the user's back.

[0168] Exemplarily, the upholstery structure 5b and the first covering layer 3b may be in an integral structure, that is, the first covering layer 3b is a soft outer skin with the upholstery structure 5b, and the soft outer skin may directly cover outer sides of the headboard frames 1b.

[0169] Exemplarily, the upholstery structure 5b and the first covering layer 3b may also be in a split structure, the upholstery structure 5b may be fixed to the headboard frames 1b first, and then the first covering layer 3b is fixed to outer sides of the headboard frames 1b covered with the upholstery by nailing, pasting or detachably connecting thereto. Alternatively, after the first covering layer 3b covers the headboard frames 1b, the upholstery structure 5b is detachably connected to the first covering layer 3b, for example, the upholstery structure 5b is adhered to the first covering layer 3b by Velcro.

[0170] It should be particularly noted that since in the unfolded state, an interval is provided between the connection position 20b between the connection member 2b and each of the headboard frames 1b and each of side edges of the two adjacent headboard frames 1b that are close to each other, bulge of the upholstery structure 5b at a folded position may be prevented by the clearance space, and a situation where the upholstery structure 5b cannot be completely folded or the upholstery structure 5b is folded too long to induce deformation of the upholstery structure 5b may also be reduced.

[0171] If the first covering layer 3b is provided with an upholstery structure 5b, when the first covering layer 3b wraps the edges of the headboard frames 1b, there may be a situation where the first covering layer 3b cannot be folded or it is difficult for the first covering layer 3b to wrap the edges since the first covering layer 3b has a too thick thickness. In view of this, the headboard further includes a second covering layer (not shown in the figures), the second covering layer is arranged between the headboard frames 1b and the first covering layer 3b, and the second covering layer covers outer sides of the two adjacent headboard frames 1b and the connection member 2b corresponding to the two adjacent headboard frames 1b respectively.

[0172] Specifically, the second covering layer may be a soft foam layer, the soft foam layer has a relatively thin thickness, to have a certain cushion effect and increase the user's comfort during usage. Since the thickness of the second covering layer is thinner than that of the upholstery structure 5b, it facilitates wrapping the edges of the headboard frames 1b when the second covering layer may cover the edges of the headboard frames 1b, to avoid a situation where it is difficult to cover the edges since it is difficult to bend the second covering layer. Furthermore, the entirety of the two adjacent headboard frames 1b and the connection member 2b between the two adjacent headboard frames 1b is wrapped by the second covering layer, to hide a transitional connection part between the two adjacent headboard frames 1b and the connection member 2b, such that there is no gap at the connection between the two headboard frames 1b after assembly; in the unfolded state, the side of the headboard facing the bed frame body 100b is still in an integral structure, and no folded gap may be seen, thereby achieving a beautiful appearance.

[0173] In an embodiment, each of the headboard frames 1b is provided with an extension part 11b at a side of each of the headboard frames 1b away from the connection member 2b, and the second covering layer further covers the extension part 11b.

[0174] In this way, after the second covering layer covers front end surfaces at sides of the headboard frames 1b facing the bed frame body 100b, the second covering layer further extends to rear end surfaces at sides of the headboard frames 1b away from the bed frame body 100b through the extension parts 11b, such that edge positions of the second covering layer may be hidden behind the headboard frames 1b; in the unfolded state, the headboard looks like an integral headboard in terms of its appearance, and no folded seam may be seen, thereby further improving aesthetics.

[0175] Exemplarily, the extension part 11b may be arranged at an edge of each of the headboard frames 1b, for example, the extension part 11b is arranged at an upper end and / or a lower end of each of the headboard frames 1b along the height direction of the headboard frames 1b, or the extension part 11b is arranged at a left end and / or a right end of each of the headboard frames 1b along the width direction of the headboard frames 1b. The extension part 11b also plays a role of increasing structural strength of each of the headboard frames 1b to a certain extent. Furthermore, an accommodation cavity is formed between the extension part 11b and each of the headboard frames 1b, and the accommodation cavity is used for receiving the bed frame body 100b in the folded state, to improve space utilization, reduce space occupied during transportation, and save transportation cost.

[0176] Since the connection member 2b is located between the first covering layer 3b and the headboard frames 1b, thickness at a position where the first covering layer 3b corresponds to the connection member 2b is greater than thickness at a position where the first covering layer 3b does not correspond to the connection member 2b, resulting in that in the unfolded state, a front end surface of the first covering layer 3b facing the bed frame body may be protruded at the position corresponding to the connection member 2b, which affects overall flatness.

[0177] In view of this, the second covering layer is provided with an avoidance structure (not shown in the figures) corresponding to the connection member 2b, and the avoidance structure is configured to avoid the connection member 2b such that in the unfolded state, sides of the first covering layer 3b away from the headboard frames 1b are flush to form a flat surface structure.

[0178] The avoidance structure may be a groove arranged in the second covering layer, that is, the groove is recessed at a side of the second covering layer facing the connection member 2b along a direction in which it goes away from the connection member 2b, and the groove is used for receiving and avoid the connection member 2b. A thickness difference between a portion of each of the headboard frames 1b corresponding to the connection member 2b and another portion of each of the headboard frames 1b not corresponding to the connection member 2b may be compensated by the avoidance structure, such that in the unfolded state, there is no situation where the front end surface of the first covering layer 3b facing the bed frame body may be protruded at the position corresponding to the connection member 2b, thereby improving overall flatness of appearance of the headboard.Sixth embodiment

[0179] The embodiment provides a bed frame, as shown in FIG. 22, the bed frame includes a bed frame body 100c and a headboard, and the headboard is connected to the bed frame body 100c. The bed frame body 100c is used for supporting a mattress, and the bed frame body 100c may include side plates, a footboard and support plates.

[0180] In actual usage, a side of the headboard faces a wall, and the wall may provide a certain support force for the headboard arranged upright; another side of the headboard faces the bed frame body 100c, to facilitate the user to lean against it and improve comfort for the usage.

[0181] If the headboard is in an integral structure, the headboard may have a relatively large volume during transportation, resulting in that it is difficult to carry and disassemble the headboard. In view of this, the embodiment provides a headboard, as shown in FIG. 23 to FIG. 26, the headboard includes a first covering layer 3c and multiple headboard frames 1c, and the first covering layer 3c covers outer sides of two adjacent headboard frames 1c from the multiple headboard frames respectively. The adjacent headboard frames 1c are connected there-between by the first covering layer 3c, and the adjacent headboard frames 1c are configured to be rotatable relative to each other around the first covering layer 3c, such that the two adjacent headboard frames 1c are switched between a folded state and an unfolded state.

[0182] The multiple headboard frames 1c are arranged along a width direction of the headboard frames 1c, that is, an arrangement direction of the multiple headboard frames 1c is the width direction of the headboard frames 1c. Exemplarily, two headboard frames 1c are provided, the two headboard frames 1c may have the same width or different widths, and in the embodiment, it is preferable that the two headboard frames 1c have the same width. The two adjacent headboard frames 1c are connected there-between by a first covering layer 3c, that is, the headboard frames are provided in a two-fold style; in some other embodiments, three headboard frames 1c are provided, and any two adjacent headboard frames 1c are connected there-between by the first covering layer 3c respectively, that is, the headboard frames are provided in a three-fold style; furthermore, the headboard frames may also be provided in other multi-fold styles.

[0183] Optionally, the first covering layer 3c is fixed to the headboard frames 1b by nailing or pasting thereto, which facilitates fixation and installation of the first covering layer 3c and has a relatively low safety cost.

[0184] The first covering layer 3c is arranged at sides of the headboard frames 1b facing the bed frame body 100c.

[0185] In this way, there is a gap between side surfaces of the two adjacent headboard frames 1c away from the bed frame body 100c, which facilitates folding the two adjacent headboard frames 1c, that is, rear side parts of the headboard may be separated from each other in the folded state; there is no gap between side surfaces of the two adjacent headboard frames 1c facing the bed frame body 100c due to presence of the first covering layer 3c, that is, front side parts of the headboard may not be separated from each other no matter in the folded state or the unfolded state, which is equivalent to covering or blocking the gap between two adjacent bed frame bodies 100c by the first covering layer 3c in the unfolded state, such that there are good usage performance and beautiful appearance.

[0186] When the unfolded state is required, side surfaces of the two adjacent headboard frames 1c facing the bed frame body 100c are rotated along a direction in which they go away from each other through the first covering layer 3c, sides of the headboard frames 1c away from the bed frame body 100c usually abut against a wall, sides of the headboard frames 1c close to the bed frame body 100c are connected by the first covering layer 3c, such that side surfaces of the headboard frames 1c close to the bed frame body 100c form a flat surface with each other, that is, a backrest surface for the user to lean against it may be formed into a flat surface, which has good comfort.

[0187] When the folded state is required, side surfaces of the headboard frames 1c away from the bed frame body 100c are separated from each other, and side surfaces of the two adjacent headboard frames 1c facing the bed frame body 100c are rotated along a direction in which they are close to each other through the first covering layer 3c, such that the two adjacent headboard frames 1c are folded to form a stacked structure, which facilitates carrying and transporting them subsequently.

[0188] In an embodiment, as shown in FIG. 26 to FIG. 29, the first covering layer 3c includes multiple covering parts 31c, and the multiple covering parts 31c cover outer sides of the multiple headboard frames 1c correspondingly, such that each of the headboard frames 1c may be completely covered and blocked by a covering part 31c corresponding thereto, to avoid a situation where the headboard frames 1c are exposed, thereby achieving good aesthetics.

[0189] The first covering layer 3c further includes a connection part 32c, the connection part 32c is arranged between two adjacent covering parts 31c from the multiple covering parts, and the adjacent headboard frames 1c are rotatable relative to each other around the connection part 32c.

[0190] The gap between the two adjacent headboard frames 1c is hidden by the connection part 32c of the first covering layer 3c, such that there is no gap between the two adjacent headboard frames 1c after assembly, when it is viewed from a front side facing the bed frame body 100c; in the unfolded state, the side of the headboard facing the bed frame body 100c is still in an integral structure, thereby achieving a beautiful appearance.

[0191] Furthermore, the connection part 32c also achieves the connection between the two adjacent headboard frames 1c, and a connection effect between the two adjacent headboard frames 1c is improved. Furthermore, the connection part 32c also provides a rotation center for the two adjacent headboard frames 1c, such that the two adjacent headboard frames 1c are rotatable relative to each other through the connection part 32c, to achieve switching between the unfolded state and the folded state.

[0192] The covering parts 31c and the connection part 32c are in an integrally formed structure.

[0193] In this way, processes of processing the covering parts 31c and the connection part 32 separately and assembling and connecting the covering parts 31c with the connection part 32c are reduced, and production cost is saved. Furthermore, the first covering layer 3c in an integrally formed structure has good overall consistency and strong aesthetics.

[0194] Exemplarily, the first covering layer 3c may be a soft outer skin, and material of the soft outer skin may be a leather material, a cloth material, etc. The first covering layer 3c may be fixed to outer sides of the headboard frames 1c by nailing or pasting thereto, or may detachably cover outer sides of the headboard frames 1c. For example, the headboard frames 1c and the first covering layer 3c may be connected there-between by Velcro.

[0195] If there is a gap between the two adjacent headboard frames 1c in the unfolded state, not only the first covering layer 3c spans across the two adjacent headboard frames 1c, but also a portion of structures of the first covering layer 3c is located between the two adjacent headboard frames 1c. Since the first covering layer 3c is made of a relatively soft material, there may be a situation where the headboard frames 1c do not have enough support strength and easily fall down.

[0196] In view of this, in the unfolded state, the two adjacent headboard frames 1c abut against each other, and a projection of the connection part 32c on a reference plane is located within projections of the two adjacent headboard frames 1c on the reference plane (as shown in FIG. 26); the reference plane is a plane where contact surfaces between the headboard frames 1c and the connection part 32c are located, that is, the reference plane may also be a plane where side surfaces of the headboard frames 1c facing the bed frame body 100c are located.

[0197] In this way, the connection part 32c completely covers the two adjacent headboard frames 1c, such that there is no gap between the two adjacent headboard frames 1c in the unfolded state. Furthermore, sides of the two adjacent headboard frames 1c that are close to each other may abut against each other, and the two adjacent headboard frames 1c may support each other, thereby increasing support strength of the headboard frames 1c and reducing a risk of the headboard frames 1c falling down.

[0198] If a side surface of the headboard frame 1c facing a bed body is non-flat or provided with a concave-convex structure, side surfaces of the two adjacent headboard frames 1c facing a bed body cannot completely fit with each other or parallel to each other in the folded state, such that the headboard may form a V-shaped structure as a whole, resulting in that the two adjacent headboard frames 1c occupy a relatively large space when they are stacked and are easy to tilt.

[0199] In order to solve this problem, as shown in FIG. 27 to FIG. 29, for the headboard provided in the embodiment, the connection part 32c has a connection position 20c for the connection part to connect with at least one of the two adjacent headboard frames 1c, or the connection part 32c has a connection position 20c for the connection part to connect with a covering part 31c from the multiple covering parts corresponding to at least one of the two adjacent headboard frames 1c, and an interval is provided between the connection position 20c and each of side edges of the two adjacent headboard frames 1c that are close to each other along an arrangement direction of multiple headboard frames 1c in the unfolded state.

[0200] Exemplarily, the connection positions 20c between the connection part 32c and the headboard frames 1c or the connection positions 20c between the connection part 32c and the covering parts 31c are not arranged along edges of the two adjacent headboard frames 1c abutting against each other in the unfolded state; instead, at the edges of the two adjacent headboard frames 1c abutting against each other, move along the arrangement direction of the multiple headboard frames 1c and toward a side where the two adjacent headboard frames 1c go away from each other, to form the connection positions 20c between the connection part 32c and the headboard frames 1c.

[0201] A clearance space is formed by the interval. In the folded state, non-flat or protruded parts of side surfaces of the headboard frames 1c facing the bed body may be avoided by the clearance space, such that side surfaces of the two adjacent headboard frames 1c facing the bed body are parallel to each other as much as possible, to reduce space occupied by the two adjacent headboard frames 1c when they are stacked, and also reduce a tilting risk.

[0202] Furthermore, in the folded state, there may be a certain movable space between the two adjacent headboard frames 1c with an action of the interval, the connection part 32c may be substantially rolled into an arc structure, and bending force may be dispersed at different positions of the connection part 32c, such that apparent crease may not appear in a middle portion of the connection part 32c.

[0203] Exemplarily, as shown in FIG. 30, each of the headboard frames 1c is provided with a first edge 100c, a second edge 102c, a third edge 103c and a fourth edge 104c connected end to end, the first edge 101c and the second edge 102c are arranged opposite to each other and distributed along the arrangement direction of the multiple headboard frames 1c, the third edge 103c and the fourth edge 104c are arranged opposite to each other. In the unfolded state, the first edges 101c of two adjacent headboard frames 1c abut against each other, and an interval is provided between the connection position 20c between the connection part 32c and each of the headboard frames 1c and the first edge 101c corresponding to the connection part 32c.

[0204] In an embodiment, the connection part 32c may have a connection position 20c for the connection part to connect with one of the two adjacent headboard frames 1c. That is, one of the two adjacent headboard frames 1c may be connected to the connection part 32c through the connection position 20c, and another one of the two adjacent headboard frames 1c may be connected to the connection part 32c in other connection ways, to achieve a single-sided connection of the connection part 32c, such that there are good freedom and flexibility.

[0205] In an embodiment, the connection part 32c has a connection position 20c for the connection part to connect with each of the two adjacent headboard frames 1c. That is, the connection part 32c is connected to the two adjacent headboard frames 1c at two sides along the arrangement direction of the multiple headboard frames 1c respectively, to achieve a double-sided connection of the connection part 32c, achieve good connection consistency, save assembly time and reduce production cost.

[0206] In an embodiment, the connection part 32c is bent or folded along the connection position 20c, when the two adjacent headboard frames 1c are in the folded state.

[0207] Since the connection part 32c is fixed to the headboard frames 1c at the connection position 20c, the connection position 20c plays a role of a rotation shaft actually, such that the connection part 32c and the headboard frames 1c are rotatable relative to each other, while the connection part 32c and the headboard frames 1c may not be separated from each other completely. Furthermore, in this way, a position where the connection part 32c is bent or folded is not limited to a middle position of the connection part 32c, to avoid a situation where crease appears only at the middle position of the connection part 32c, thereby improving overall aesthetics in the unfolded state.

[0208] In an embodiment, as shown in FIG. 30, the interval provided between the connection position 20c and each of side edges of the two adjacent headboard frames 1c that are close to each other along the arrangement direction of the multiple headboard frames 1c in the unfolded state is d, here d ≥ 1 cm. With the interval d ≥ 1 cm, the connection part 32c obtains a movable space with a width of at least 1 cm in the folded state, thereby improving an avoidance effect.

[0209] Furthermore, 1.5 cm ≤ d ≤ 5 cm. For example, d may be 1.5 cm, 2 cm, 3 cm, 5 cm, etc.

[0210] If each of the headboard frames 1c is provided with a relatively large protruded part, the thicker the thickness of the protruded part, the larger the required avoidance space. The interval d is set between 1.5 cm and 5 cm, and the interval d is matched with the protruded part of each of the headboard frames 1c to the maximum extent, thereby improving flatness of the headboard and bed frame 1 in the folded state.

[0211] It may be understood that when the headboard frames 1c are switched between the unfolded state and the folded state, one of the headboard frames 1c may drive another one of the headboard frames 1c to swing through the connection part 32c due to heavy weights of the headboard frames 1c, inducing a situation where tearing appears between the connection part 32c and the headboard frames 1c. Along an arrangement direction of the two adjacent headboard frames 1c, there is a certain distance between the connection position 20c between the connection part 32c and each of the headboard frames 1c and the corresponding edge of each of the headboard frames 1c, such that a certain margin of activity may be added.

[0212] It may be understood that the bed frame may further include a connection member, the connection member is arranged between the headboard frames 1c and the first covering layer 3c, and the connection member is arranged between the two adjacent headboard frames 1c, such that there is no gap between the two adjacent headboard frames 1c in the unfolded state, thereby achieving a good appearance. Furthermore, the connection member as provided separately may also reduce a risk of easy abrasion of the connection part 32c in a process of unfolding and folding repeatedly.

[0213] In an embodiment, as shown in FIG. 31, each of the headboard frames 1c is provided with an abutment part 12c at a side of each of the headboard frames 1c away from the bed frame body 100c, and the abutment parts 12c corresponding to the two adjacent headboard frames 1c abut against each other in the unfolded state. In this way, a contact area between the two adjacent headboard frames 1c is increased in the unfolded state, thereby improving abutment stability and support strength.

[0214] It may be understood that the two adjacent headboard frames 1c are in a split structure, then the abutment parts 12c corresponding to the two adjacent headboard frames 1c are also in a split structure, and an edge of each of the abutment parts 12c is flush with an edge of a corresponding one of the headboard frames 1c along a direction in which the two adjacent headboard frames 1c are close to each other. In the unfolded state, the two adjacent headboard frames 1c are located on the same horizontal line, and the abutment parts 12c corresponding to the two adjacent headboard frames 1c abut against each other, thereby effectively improving strength and support performance of the two adjacent headboard frames 1c at a position where they are arranged in sections.

[0215] The abutment part 12c may be arranged at any position of each of the headboard frames 1c along a height direction of the headboard frames 1c, or the abutment part 12c and an extension part 11c may be in an integrally formed structure, thereby reducing assembly processes of parts and saving production cost.

[0216] In an embodiment, as shown in FIG. 32, the headboard further includes a fixation member 4c, the fixation member 4c is arranged at a side of each of the headboard frames 1c away from the bed frame body 100c, and the two adjacent headboard frames 1c are detachably connected there-between by the fixation member 4c.

[0217] In the unfolded state, the two adjacent headboard frames 1c are connected there-between by the fixation member 4c, such that the two adjacent headboard frames 1c do not rotate relative to each other during usage. In the folded state, the fixation member 4c is removed, the two adjacent headboard frames 1c are rotated along a direction in which they are close to each other and folded together, such that the headboard has a small package volume to facilitate transportation and storage.

[0218] Exemplarily, the fixation member 4c is connected to the headboard frames 1c by at least one of bolt connection or snap-fit connection, to facilitate installation and disassembly, and achieve more flexible switching between the unfolded state and the folded state.

[0219] Exemplarily, the fixation member 4c is at least one of a rod-shaped structure or a U-shaped buckle. When the fixation member 4c is a U-shaped buckle, an open end of the U-shaped buckle faces the headboard frames 1c and clamps edges of the two adjacent headboard frames 1c. When the fixation member 4c is in a rod-shaped structure, the fixation member 4c may span across the two adjacent headboard frames 1c, and the fixation member 4c is fixed to the two adjacent headboard frames 1c by bolts, such that the headboard may be stably used in the unfolded state.

[0220] Exemplarily, the fixation member 4c includes multiple fixation members, the multiple fixation members 4c are arranged along a height direction of the headboard frames 1c, and the height direction of the headboard frames 1c is perpendicular to an arrangement direction of the multiple headboard frames 1c.

[0221] For example, the fixation member 4c includes two fixation members, the two fixation members 4c are located above and below at sides of the headboard frames 1c away from the connection part 32c respectively, thereby improving a fixing effect between the two adjacent headboard frames 1c in the unfolded state.Seventh embodiment

[0222] The embodiment is similar to the first embodiment, and a difference of the embodiment compared to the first embodiment lies only in a specific structure of the first covering layer 3c.

[0223] As shown in FIG. 33 to FIG. 35, the first covering layer 3c provided in the embodiment includes an upholstery structure 5c. The upholstery structure 5c may be a foam, which may provide good support and cushion functions for the user's back.

[0224] Exemplarily, the upholstery structure 5c and the first covering layer 3c may be in an integral structure, that is, the first covering layer 3c is a soft outer skin with the upholstery structure 5c, and the soft outer skin may directly cover outer sides of the headboard frames 1c.

[0225] Exemplarily, the upholstery structure 5c and the first covering layer 3c may also be in a split structure, the upholstery structure 5c may be fixed to the headboard frames 1c first, and then the first covering layer 3c is fixed to outer sides of the headboard frames 1c covered with the upholstery by nailing, pasting or detachably connecting thereto. Alternatively, after the first covering layer 3c covers the headboard frames 1c, the upholstery structure 5c is detachably connected to the first covering layer 3c, for example, the upholstery structure 5c is adhered to the first covering layer 3c by Velcro.

[0226] It should be particularly noted that since in the unfolded state, an interval is provided between the connection position 20c between the connection part 32c and each of the headboard frames 1c and each of side edges of the two adjacent headboard frames 1c that are close to each other, bulge of the upholstery structure 5c at a folded position may be prevented by the clearance space, and a situation where the upholstery structure 5c cannot be completely folded or the upholstery structure 5c is folded too long to induce deformation of the upholstery structure 5c may also be reduced.

[0227] If the first covering layer 3c is provided with an upholstery structure 5c, when the first covering layer 3c wraps the edges of the headboard frames 1c, there may be a situation where the first covering layer 3c cannot be folded or it is difficult for the first covering layer 3c to wrap the edges since the first covering layer 3c has a too thick thickness. In view of this, the headboard further includes a second covering layer (not shown in the figures), the second covering layer is arranged between the headboard frames 1c and the first covering layer 3c, and the second covering layer covers outer sides of the two adjacent headboard frames 1c and the connection part 32c corresponding to the two adjacent headboard frames 1c respectively.

[0228] Specifically, the second covering layer may be a soft foam layer, the soft foam layer has a relatively thin thickness, to have a certain cushion effect and increase the user's comfort during usage. Since the thickness of the second covering layer is thinner than that of the upholstery structure 5c, it facilitates wrapping the edges of the headboard frames 1c when the second covering layer may cover the edges of the headboard frames 1c, to avoid a situation where it is difficult to cover the edges since it is difficult to bend the second covering layer. Furthermore, the entirety of the two adjacent headboard frames 1c is wrapped by the second covering layer, to hide the gap between the two adjacent headboard frames 1c, such that there is no gap between the two headboard frames 1c after assembly; in the unfolded state, the side of the headboard facing the bed frame body 100c is still in an integral structure, and no folded gap may be seen, thereby achieving a beautiful appearance.

[0229] In an embodiment, each of the headboard frames 1c is provided with an extension part 11c at a side of each of the headboard frames 1c away from the connection part 32c, and the second covering layer further covers the extension part 11c.

[0230] In this way, after the second covering layer covers front end surfaces at sides of the headboard frames 1c facing the bed frame body 100c, the second covering layer further extends to rear end surfaces at sides of the headboard frames 1c away from the bed frame body 100c through the extension parts 11c, such that edge positions of the second covering layer may be hidden behind the headboard frames 1c; in the unfolded state, the headboard looks like an integral headboard in terms of its appearance, and no folded seam may be seen, thereby further improving aesthetics.

[0231] Exemplarily, the extension part 11c may be arranged at an edge of each of the headboard frames 1c, for example, the extension part 11c is arranged at an upper end and / or a lower end of each of the headboard frames 1c along the height direction of the headboard frames 1c, or the extension part 11c is arranged at a left end and / or a right end of each of the headboard frames 1c along the width direction of the headboard frames 1c. The extension part 11c also plays a role of increasing structural strength of each of the headboard frames 1c to a certain extent. Furthermore, an accommodation cavity is formed between the extension part 11c and each of the headboard frames 1c, and the accommodation cavity is used for receiving the bed frame body 100c in the folded state, to improve space utilization, reduce space occupied during transportation, and save transportation cost.
