Description

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 base and a backrest. The base is used to support the mattress and provide comfortable support for the user, and the backrest can be leaned on by the user to provide leaning support. The existing backrest includes a back panel and a covering layer provided on the back panel. The existing covering layer is usually ordinary sponge, doll cotton, down, etc., which not only causes the softness and hardness of each area of the backrest to have no difference, and cannot provide differential support for the user's back and waist, affecting the leaning comfort, but also easily collapses after long-term use, resulting in the deformation of the backrest contour and unable to fit with the user's back, affecting the use experience. In addition, when using doll cotton or down, the situation of cotton running is likely to occur, resulting in the loss of raw materials of the backrest and affecting the comfort. Content of the Utility Model

[0003] In order to solve the deficiencies of the existing technology, the utility model provides a bed frame, on which a 3D filling layer is arranged on the backrest, which can not only recover the deformation in time after pressure relief, but also set partitions with differential hardness according to needs, and can also avoid the situation of cotton running, improving the use experience.

[0004] The utility model is realized in the following way: A bed frame includes a base and a backrest. A back panel is arranged inside the backrest, and a 3D filling layer is arranged on the leaning surface of the back panel. The 3D filling layer includes multiple partitions with differential hardness. By arranging the 3D filling layer on the leaning surface of the back panel and utilizing the characteristics of good elasticity and controllable softness and hardness of the 3D filling layer, it not only ensures that the 3D filling layer can recover its original shape in time when the pressure is released, preventing the backrest from collapsing, but also can form partitions with differential hardness in different areas to provide differential support for each area of the user's waist and back, and can also prevent the situation of cotton running by replacing the original material, effectively improving the use experience.

[0005] Preferably, the partitions obtain the preset hardness by setting differential density. Different densities can be set during the processing of the 3D filling layer. The greater the density, the harder it is, and vice versa, the smaller the density, the softer it is, thus forming partitions with differential hardness to improve the leaning comfort.

[0006] Preferably, the partitions obtain the preset hardness by setting differential thickness. Different thicknesses can be set during the processing of the 3D filling layer. The greater the thickness, the softer it is, and vice versa, the smaller the thickness, the harder it is, thus forming partitions with differential hardness to improve the leaning comfort.

[0007] Preferably, an arc-shaped surface bulging outward in the middle is formed on the outer side wall of the partition facing away from the back plate. By providing the arc-shaped surface to fit the surface of the user's waist and back, the contact area is increased to improve the comfort of leaning and support.

[0008] Preferably, at least two layers with different densities are provided in the partition, so that each layer in the partition has different hardness. The layers are stacked to form the partition, and each layer has a different density, so that the support performance of the partition has diversity. The harder layer is used to provide support, and the softer layer is used to provide comfort.

[0009] Preferably, the 3D filling layer is divided into two partitions, including an upper partition and a lower partition, and the hardness of the upper partition is less than that of the lower partition. The upper partition is for the user's back to lean on, and the lower partition is for the user's waist to lean on. Since the hardness of the lower partition is greater than that of the upper partition, the user's waist will obtain better support, and the back will obtain better comfort.

[0010] Preferably, a sponge layer is provided between the back plate and the 3D filling layer. By providing the sponge layer, the thickness of the backrest is increased, the thickness of the 3D filling layer is reduced to lower the raw material cost, and the decoration requirement is met. It can also play a role in isolating the back plate and the 3D filling layer, and use the deformation of the sponge layer itself to offset the deformation generated by the 3D filling layer to improve the comfort of leaning.

[0011] Preferably, a flexible layer with equal thickness is provided on the side of the 3D filling layer facing away from the back plate. The flexible layer completely covers the outer side wall of the 3D filling layer facing away from the back plate. The flexible layer is a sponge layer or a fiber filling layer, and the fiber filling layer is preferably made of silk floss. The flexible layer matches and fits the user's surface through its own deformation, and disperses the leaning force exerted by the user on the backrest by increasing the contact area between the backrest and the user.

[0012] Preferably, the backrest includes an external covering layer. The peripheral edge of the covering layer is connected to the back plate to form a receiving cavity, so that the sponge layer, the 3D filling layer and the flexible layer are stacked in sequence and wrapped in the receiving cavity. The covering layer not only plays a role of clamping and positioning the sponge layer, the 3D filling layer and the flexible layer by being fixedly connected to the back plate, but also plays a role of hiding and protecting the sponge layer, the 3D filling layer and the flexible layer to prevent foreign dirt from entering, and also plays a role of decorating the backrest. The peripheral edge of the covering layer is fixedly connected to the peripheral edge of the back plate, so that the sponge layer, the 3D filling layer and the flexible layer are wrapped in the receiving cavity to prevent the sponge layer, the 3D filling layer and the flexible layer from shifting during pressure release and reset.

[0013] Preferably, a horizontally penetrating partition belt is provided in the middle of the coating layer. The partition belt penetrates through the coating layer and is fixedly connected to the sponge layer, the 3D filling layer, and the flexible layer, which not only plays a fixing role in the middle of the sponge layer, the 3D filling layer, and the flexible layer to prevent force offset, but also shapes the backrest contour, provides leaning support for different regions of the user's waist and back respectively, and improves comfort and aesthetics.

[0014] The beneficial effects of the present utility model are as follows: A 3D filling layer is provided on the leaning surface of the back panel. By utilizing the characteristics of good elasticity and controllable softness and hardness of the 3D filling layer, it not only ensures that the 3D filling layer can promptly return to its original shape when relieving pressure to prevent the backrest from collapsing, but also can form partitions with different hardnesses in different regions to provide different supports for different regions of the user's waist and back, and can also prevent cotton running by replacing the original material, effectively improving the use experience.

[0020] The following further illustrates the substantial features of the present utility model in conjunction with the attached drawings and specific embodiments.

[0021] As Figure 1 shown, a bed frame includes a base 1 and a backrest 2. A back panel 10 is provided inside the backrest 2. A 3D filling layer 3 is provided on the leaning surface of the back panel 10. The 3D filling layer 3 includes multiple partitions with different hardnesses. By providing the 3D filling layer 3 on the leaning surface of the back panel 10 and utilizing the characteristics of good elasticity and controllable softness and hardness of the 3D filling layer 3, it not only ensures that the 3D filling layer 3 can promptly return to its original shape when relieving pressure to prevent the backrest 2 from collapsing, but also can form partitions with different hardnesses in different regions to provide different supports for different regions of the user's waist and back, and can also prevent cotton running by replacing the original material, effectively improving the use experience.

[0022] In actual operation, the 3D filling layer 3 is divided into two partitions, including an upper placement area 4 and a lower placement area 5, and the hardness of the upper placement area 4 is less than that of the lower placement area 5. The upper placement area 4 is for the user's back to lean on, and the lower placement area 5 is for the user's waist to lean on. The hardness of the upper placement area 4 is less than that of the lower placement area 5, which not only ensures that the user's waist obtains rigid support, but also ensures that the user's back obtains flexible support by squeezing the softer upper placement area 4. The user's back is effectively positioned by being embedded in the upper placement area 4, preventing the user from leaning on the backrest 2 and tilting laterally.

[0023] In actual operation, the 3D filling layer 3 is made of air fiber material, which is not only convenient for processing but also effectively reduces costs. During processing, the raw material is softened by heating and then extruded into raw material filaments, and the raw material filaments are stacked and cooled to form the 3D filling layer 3. The partition can be achieved in various forms, which not only ensures that the backrest 2 meets the user's usage requirements but also facilitates processing and production. Specifically, the formation of partitions with different hardnesses includes but is not limited to the following methods:

[0024] Method 1: The partition obtains a preset hardness by setting different densities. Since the 3D filling layer 3 is formed by stacking and extrusion of fiber materials during processing, different numbers of raw materials are stacked in a unit volume to obtain different densities, and then partitions with different hardnesses are obtained;

[0025] Method 2: The partition obtains a preset hardness by setting different thicknesses. Since the 3D filling layer 3 is formed by stacking and extrusion of fiber materials during processing, different thicknesses are stacked to obtain a preset hardness, and then partitions with different hardnesses are obtained;

[0026] Method 3: At least two layers with different densities are provided in the partition so that each layer in the partition has different hardnesses. On the basis of Method 1, further improvements are made by setting layers with different hard densities in the partition (as shown in Figure 4 ), so that each partition can show different hardnesses when compressed and deformed, thereby improving the leaning comfort.

[0027] The above methods can be implemented alone or in combination according to needs, so that the backrest 2 has diverse support characteristics, and all should be regarded as specific embodiments of the present invention.

[0028] In actual operation, the backrest 2 includes an external covering layer 8, and a horizontally penetrating partition belt 9 is provided in the middle of the covering layer 8 (as shown in Figure 3As shown in the figure. The backrest 2 is divided into the upper area 4 and the lower area 5 by the partition belt 9 to ensure that each partition area can effectively support the corresponding area of the user's waist and back, thereby improving the leaning comfort. During installation, the partition belt passes through the covering layer and is sewn and fixedly connected to the sponge layer 6, the 3D filling layer 3 and the flexible layer 7 to ensure the relative positions of the sponge layer 6, the 3D filling layer 3 and the flexible layer 7 are fixed.

[0029] In actual operation, a sponge layer 6 is provided between the back panel 10 and the 3D filling layer 3 (as Figure 2 shown in the figure). A flexible layer 7 is provided on the side of the 3D filling layer 3 facing away from the back panel 10. The periphery of the covering layer 8 is connected to the back panel 10 to form a receiving cavity, so that the sponge layer 6, the 3D filling layer 3 and the flexible layer 7 are stacked in sequence and wrapped in the receiving cavity. During installation, the sponge layer 6, the 3D filling layer 3 and the flexible layer 7 are sequentially covered on the back panel 10. The periphery of the covering layer 8 is fixedly connected to the periphery of the back panel 10, and the middle part abuts against the flexible layer 7. The covering layer 8 not only plays a role in clamping and positioning the sponge layer 6, the 3D filling layer 3 and the flexible layer 7 to prevent relative displacement between the sponge layer 6, the 3D filling layer 3 and the flexible layer 7, but also plays a protective role for the sponge layer 6, the 3D filling layer 3 and the flexible layer 7 to prevent dust from entering the receiving cavity, and can also play a decorative role to improve the aesthetics of the backrest 2.

[0030] In actual operation, when the flexible layer 7 is a fiber filling layer, the 3D filling layer 3 and the flexible layer 7 need to be wrapped and isolated by sleeving an outer cover to prevent the filamentous materials in the flexible layer 7 from being embedded in the 3D filling layer 3.

[0031] In actual operation, the outer side wall of the partition area facing away from the back panel 10 forms an arc surface bulging outwards in the middle. By setting the special-shaped flexible layer 7 to change the surface contour of the partition area, it is convenient for the surface of the partition area to fit with the user's waist and back, and the leaning comfort is improved by increasing the base area.

[0032] In actual operation, the flexible layer 7 completely covers the outer side wall of the 3D filling layer 3 facing away from the back panel 10. The flexible layer 7 is a silk cotton filling layer, a sponge layer or a fiber filling layer. The flexible layer 7 is easy to deform and can be deformed under force when the user leans on it, so as to match and fit with the user's waist and back.
