Technical Field
[0001] The utility model relates to the field of bedding, and particularly to a bed frame. Background Art
[0002] The existing bed frame includes a bed body and a backrest arranged at the front edge of the bed body. The width of the backrest is equal to or slightly larger than the width of the bed body, which can not only provide a leaning function for users, but also play a decorative role. However, this bed frame structure has the following defects: the small width of the backrest not only results in a single function of the backrest, but also leads to too small a display area of the backrest, affecting the decorative beauty and the use experience. Content of the Utility Model
[0003] In order to solve the deficiencies of the existing technology, the utility model provides a bed frame, in which a secondary backrest that can swing and switch between a guardrail state and a display screen state is arranged on the side edge of the main backrest. The secondary backrest in the guardrail state can be used to play a guarding role, improving the practicality, and the secondary backrest in the display screen state can be used to play a decorative role, improving the beauty.
[0004] The utility model is realized in the following way: a bed frame includes a bed body and a backrest assembly arranged at the front edge of the bed body. The backrest assembly includes a central main backrest and a secondary backrest arranged on the side edge of the main backrest. The secondary backrest can swing and switch between a guardrail state and a display screen state. Arranging a secondary backrest that can swing and switch between a guardrail state and a display screen state on the side edge of the main backrest can not only use the secondary backrest in the guardrail state to play a guarding role for children, preventing falls by restricting the activity range of children, improving the practicality, but also use the secondary backrest in the display screen state to play a decorative role. The secondary backrest and the main backrest are combined to form a display surface, effectively improving the beauty.
[0005] Preferably, the included angle between the secondary backrest and the main backrest is A, and 90°≤A≤180°, so that the secondary backrest can swing and switch between a guardrail state and a display screen state. The included angle between the rear wall of the secondary backrest and the rear wall of the main backrest is A, and the secondary backrest can swing reciprocally within a preset angle range, which is convenient for the secondary backrest to switch between different states to achieve different functions. The parameter A is set between 90° and 180°, and the swing range of the secondary backrest can be limited by the wall surface and the side edge of the bed body to ensure that the secondary backrest swings freely within the preset range.
[0006] Preferably, when the secondary backrest is in the guardrail state, A = 90°, and the secondary backrest is attached to the side edge of the bed body and is perpendicular to the main backrest. The secondary backrest is attached to the side edge of the bed frame, preventing children from falling by eliminating the gap between them, improving the use safety.
[0007] Preferably, when the secondary backrest is in the screen display state, 90° < A ≤ 180°, and the rear walls of the secondary backrest and the main backrest are joined together to form a display surface that is open towards the bed body. The parameter A is adjustable. By increasing the parameter A, the width of the display surface can be effectively increased, thereby enhancing the aesthetics. By decreasing the parameter A, the anti-tipping performance of the backrest assembly can be improved.
[0008] Preferably, there are two secondary backrests symmetrically disposed on both side edges of the main backrest. The secondary backrests can swing independently and freely switch between the guardrail state and the screen display state. The symmetrical arrangement of the secondary backrests not only enhances the aesthetics by increasing the width of the display surface but also ensures that both sides of the bed body can be blocked by the secondary backrests in the guardrail state, improving the safety in use.
[0009] Preferably, the width of the main backrest is the same as the width of the front edge of the bed body to form an activity space for the secondary backrest to swing on both sides outside the front part of the bed body. The secondary backrest can swing around the side edge of the main backrest. The side edge of the main backrest is located at the end of the front edge of the bed body, ensuring that the secondary backrest can swing freely within the activity space outside the bed body.
[0010] Preferably, the main backrest includes a main board, and the secondary backrest includes a secondary board. The side edge of the main board is connected to the corresponding side edge of the secondary board through a hinge. The connection between the main board and the secondary board through the hinge not only ensures the firm connection between the main backrest and the secondary backrest but also ensures that the secondary backrest can swing freely around the hinge.
[0011] Preferably, horizontal installation grooves are provided on the rear wall side edges of both the main board and the secondary board. The end of the hinge is inserted into the corresponding installation groove and fixed and locked by a fastener, so that the secondary backrest swings and switches under the guidance of the hinge. The installation groove provides an installation space for the end of the hinge. It not only improves the connection reliability by increasing the contact area between the end of the hinge and the corresponding installation groove, ensuring that the secondary board swings around the hinge, but also hides the end of the hinge through the installation groove, ensuring the flatness of the rear wall surfaces of the main board and the secondary board, effectively eliminating the sense of foreign objects and improving the comfort of leaning.
[0012] Preferably, an assembly operation groove is formed by upward extension in the middle of the installation groove. The fastener passes through the assembly operation groove and screws and locks the end of the hinge on the bottom wall of the installation groove. The fastener passes through the end of the hinge in a vertically oriented posture and is screwed and locked with the groove wall of the installation groove. The assembly operation groove can provide the space required for the vertical placement of the fastener, facilitating disassembly, installation, and maintenance.
[0013] Preferably, the main board and the secondary board are connected by at least two separately disposed hinges. By increasing the number of hinges, it ensures that the secondary board swings in a preset posture and around a preset center, ensuring that the secondary board can be reliably positioned in the guardrail state and the screen display state. By restricting the number of hinges, it improves the assembly efficiency and reduces the cost.
[0014] Preferably, screw holes are provided on the bottom wall of the installation groove, and screw pipes with internal and external threads are embedded in the screw holes. The fasteners pass through the end of the hinge and are screwed and locked with the screw pipes. The screw pipes are screwed in the screw holes, and the fasteners are screwed and fixed with the screw pipes, which not only simplifies the on-site assembly process by embedding the screw pipes, but also effectively improves the connection reliability between the end of the hinge and the wall of the installation groove, and ensures the precise assembly of the end of the hinge with the installation groove, ensuring the precise swing of the auxiliary backrest.
[0015] Preferably, the main backrest includes a main sponge layer and a main surface cover layer that are sequentially wrapped and covered on the main board, and the auxiliary backrest includes an auxiliary sponge layer and an auxiliary surface cover layer that are sequentially wrapped and covered on the auxiliary board. By providing the main sponge layer and the auxiliary sponge layer, the elasticity of the backrest assembly is improved to provide comfortable support for the user, and by providing the main surface cover layer and the auxiliary surface cover layer, the decorative beauty is improved.
[0016] The beneficial effects of the present utility model are as follows: An auxiliary backrest that can swing and switch between the guardrail state and the display screen state is provided on the side edge of the main backrest. It can not only use the auxiliary backrest switched to the guardrail state to play a role in guarding children, prevent the occurrence of falling by restricting the activity range of children, and improve the practicality, but also use the auxiliary backrest switched to the display screen state to play a decorative role. The auxiliary backrest and the main backrest are combined to form a display surface, effectively improving the beauty. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0023] The following further illustrates the essential features of the present utility model in conjunction with the accompanying drawings of the specification and the specific embodiments.
[0024] As shown in Figure 1And 2 A bed frame as shown, including a bed body 1 and a backrest assembly 2 provided at the front edge of the bed body 1. The backrest assembly 2 includes a central main backrest 3 and auxiliary backrests 4 provided at the side edges of the main backrest 3. The auxiliary backrests 4 can swing and switch between a guardrail state and a display screen state. By providing the auxiliary backrests 4 that can swing and switch between a guardrail state and a display screen state at the side edges of the main backrest 3, not only can the auxiliary backrests 4 switched to the guardrail state play a role in guarding children, preventing falls by restricting the activity range of children, and improving practicality, but also the auxiliary backrests 4 switched to the display screen state can play a decorative role. The auxiliary backrests 4 and the main backrest 3 are combined to form a display surface, effectively improving the aesthetics.
[0025] In actual operation, the included angle A between the auxiliary backrest 4 and the main backrest 3 is such that 90° ≤ A ≤ 180°, so that the auxiliary backrest 4 can swing and switch between a guardrail state and a display screen state.
[0026] When the auxiliary backrest 4 is in the guardrail state, A = 90°. The auxiliary backrest 4 and the main backrest 3 are perpendicular to each other. The auxiliary backrest 4 is closely attached to the side edge of the bed body 1, and the main backrest 3 is closely attached to the front edge of the bed body 1, so that the front edge of the bed body 1 is covered by the backrest assembly 2, preventing children on the bed body 1 from falling by eliminating the gap between the backrest assembly 2 and the front edge of the bed body 1, ensuring the safety of children.
[0027] When the auxiliary backrest 4 is in the display screen state, 90° < A ≤ 180°. The rear walls of the auxiliary backrest 4 and the main backrest 3 are combined to form a display surface facing the bed body 1. The rear walls of the auxiliary backrest 4 and the main backrest 3 are combined to form a display surface, improving the aesthetics of the backrest assembly 2 by increasing the display surface. The parameter A can be adjusted as needed to obtain corresponding advantages: when A = 180°, the auxiliary backrest 4 and the main backrest 3 are in the same plane, not only can a larger-sized display surface be obtained, but also it is ensured that the auxiliary backrest 4 can be attached to the wall and the occupied space of the backrest assembly 2 is reduced; when 90° < A < 180°, the auxiliary backrest 4 and the main backrest 3 are in different planes, effectively increasing the thickness of the backrest assembly 2, and further improving the anti-tipping performance of the backrest assembly 2. The smaller the parameter A, the better the anti-tipping performance of the backrest assembly 2, and the larger the parameter A, the wider the display surface.
[0028] In actual operation, the secondary backrests 4 are two pieces and are symmetrically arranged on both side edges of the main backrest 3. The secondary backrests 4 can swing independently and freely switch between the guardrail state and the display screen state. The secondary backrests 4 are two pieces and are symmetrically arranged on both sides of the main backrest 3, which not only improves the aesthetics but also ensures that both sides of the front part of the bed frame can be blocked by the corresponding secondary backrests 4, effectively improving the guard effect. The secondary backrests 4 located on both sides of the main backrest 3 can be independently adjusted as needed. The situations where the two secondary backrests 4 can be respectively switched to the display screen state and the guardrail state should be regarded as specific embodiments of the present invention.
[0029] In actual operation, the width of the main backrest 3 is the same as the width of the front edge of the bed body 1 to form an activity space for the secondary backrest 4 to swing outside both sides of the front part of the bed body 1, which not only ensures that the secondary backrest 4 can swing freely in the activity space but also ensures that the secondary backrest 4 can be closely attached to the side edge of the bed body 1 when switched to the guardrail state, preventing children from getting stuck in the gap between the secondary backrest 4 and the side edge of the bed body 1.
[0030] As Figure 3 shown, the main backrest 3 includes a main board 5, a main sponge layer 11 and a main surface cover layer 12 that are sequentially wrapped and covered on the main board 5. The secondary backrest 4 includes a secondary board 6, a secondary sponge layer 13 and a secondary surface cover layer 14 that are sequentially wrapped and covered on the secondary board 6. By providing the main sponge layer 11 and the secondary sponge layer 13, it is ensured that the backrest assembly 2 has good elastic deformation to meet the comfort requirements of the user when leaning. By providing the main surface cover layer 12 and the secondary surface cover layer 14 with different materials and patterns, the decorative effect of the backrest assembly 2 is improved, thereby enhancing the aesthetics. The main surface cover layer 12 and the secondary surface cover layer 14 are leather or fabric covering the surface of the backrest assembly 2 and having decorative and protective functions. The thickness of the main sponge layer 11 covering the rear wall area of the main board 5 is greater than the thickness of the main sponge layer 11 covering the front wall area of the main board 5. The thickness of the secondary sponge layer 13 covering the rear wall area of the secondary board 6 is greater than the thickness of the secondary sponge layer 13 covering the front wall area of the secondary board 6. The comfort of the user when leaning is improved by increasing the deformable range.
[0031] In actual operation, the side edge of the main board 5 is connected to the side edge of the corresponding secondary board 6 through a hinge 7. Horizontal installation grooves 8 are provided on the rear wall side edges of the main board 5 and the secondary board 6 (as Figure 4 shown). The end of the hinge 7 is inserted into the corresponding installation groove 8 and is fixedly connected and locked by a fastener 15, so that the secondary backrest 4 swings and switches under the guidance of the hinge 7. One end of the hinge 7 is inserted and fixedly connected to the installation groove 8 provided on the side edge of the main board 5, and the other end is inserted and fixedly connected to the installation groove 8 provided on the side edge of the secondary board 6. The main board 5 and the secondary board 6 are connected through at least two separately arranged hinges 7. The two hinges 7 can rotate concentrically, ensuring that the secondary board 6 can swing along a preset path in a preset posture, thereby ensuring that the secondary backrest 4 accurately switches between the guardrail state and the display screen state.
[0032] In actual operation, the hinge 7 is a stepless hinge 7, which can not only arbitrarily adjust the included angle between the components at both ends of the hinge 7 according to needs to meet the swinging requirements of the auxiliary backrest 4, but also position the auxiliary backrest 4 after the auxiliary backrest 4 swings to a specified position to ensure the reliable positioning of the auxiliary backrest 4 and prevent the auxiliary backrest 4 from affecting the use experience due to deflection under force.
[0033] In actual operation, screw holes are provided on the bottom wall of the installation groove 8, and screw pipes 10 with internal and external threads are embedded in the screw holes. The fastener 15 passes through the end of the hinge 7 and is screwed and locked with the screw pipe 10. The screw pipe 10 is embedded, which not only facilitates the user to perform precise assembly at the assembly site, but also improves the connection reliability between the end of the hinge 7 and the installation groove 8. A plurality of separate screw pipes 10 are arranged between the end of the hinge 7 and the corresponding installation groove 8 to improve the connection reliability by increasing the number of fasteners 15.
[0034] In actual operation, the end of the hinge 7 is fixedly connected to the bottom wall of the installation groove 8 through the fastener 15. For the convenience of installation, an assembly operation groove 9 is formed by extending upward in the middle of the installation groove 8 (as Figure 5 shown), and the fastener 15 passes through the assembly operation groove 9 and screws and locks the end of the hinge 7 to the bottom wall of the installation groove 8. The assembly operation groove 9 provides a space for accommodating the vertically arranged fastener 15, facilitating the fastener 15 to pass through the end of the hinge 7 from top to bottom and be screwed and locked with the corresponding screw pipe 10.
