Description

Technical Field

[0001] This utility model relates to the field of bedding, and more specifically, to an electric bed structure that enhances mattress support. Background Technology

[0002] Electric beds offer two usage postures: one is similar to a traditional bed, where the user lies on the bed; the other is with the headboard raised, allowing the user to recline semi-reclined. Traditional electric beds consist of a raised headboard and a connecting frame, with a motor driving the headboard to rotate relative to the connecting frame. However, this design has the following problems: When the backrest is raised, the mattress is forced to deform, causing it to no longer conform to the body at the lumbar region, resulting in a loss of lumbar support. This phenomenon is referred to as "unsupported" in the following description. Another problem is that in order to achieve a proper posture, the rotation angle between the backrest and the buttocks is relatively large. This rotation angle can damage the quality of the mattress, causing excessive deformation or tearing in the lumbar region.

[0003] Based on the above shortcomings, this application aims to provide an electric bed structure that improves mattress support by setting a segmented back panel, which enables the mattress to provide effective support for the lower back and reduces damage to the mattress. Utility Model Content

[0004] This invention overcomes the problem in existing electric bed structures where the mattress is suspended in the lumbar region when the backrest is raised, resulting in poor lumbar support and significant damage to the mattress. It provides an electric bed structure that improves mattress support, effectively enhancing the user's support experience, especially providing more ergonomic support in the lumbar region, and also protecting the mattress during use.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: An electric bed structure for improving mattress support includes a driver, a base, a backrest and a backrest mounted on the base. The driver drives the backrest to rotate relative to the base. The backrest includes a first backrest and a second backrest. The second backrest is hinged to the backrest. The first backrest and the second backrest are rotatably connected by a limiting hinge. The limiting hinge has a limiting angle β, which is an obtuse angle. The driver drives the first backrest to rotate relative to the second backrest to the limiting angle β. After that, the first backrest and the second backrest rotate together relative to the backrest.

[0006] The electric bed structure provides lumbar support and protects the mattress during the lifting process. During rotation, the first backrest first rotates relative to the second backrest, then its angle with the second backrest is fixed by a limiting hinge, and finally it rotates together with the second backrest relative to the headboard, thus providing lumbar support. The advantages of this structure are twofold: firstly, when the first and second backrests rotate together, the second backrest acts as a transition between the first and headboards, providing lumbar support in a more ergonomic way; secondly, when the first backrest rotates to the same angle as the headboard, the presence of the second backrest makes the angles between the first and second backrests, and between the second backrest and the headboard, smaller than the angle between the backrests directly connecting to the headboard, thus being more mattress-friendly and preventing deformation or tearing during use.

[0007] Preferably, the driver is connected to a rotating rod, which is hinged to the base. The rotating rod is driven to rotate around its axis via telescopic movement. An abutment rod is fixedly connected to the rotating rod, and an abutment roller is provided at the free end of the abutment rod. The abutment roller abuts against and slides against the first back plate to drive the first back plate. The abutment rod, driven by the rotating rod, abuts against the first back plate, thus pushing the first back plate. The abutment roller is designed to prevent damage to the first back plate.

[0008] Preferably, the actuator includes an extension rod, the length of which is adjusted by an external input. A rocker arm is hinged to the free end of the extension rod, and a rotating rod is connected to the other end of the rocker arm. The actuator inputs torque to the rotating rod by extending and retracting the extension rod. Power transmission and conversion are achieved via this path: extension rod - rocker arm - rotating rod - abutment rod.

[0009] Preferably, the length of the rocker arm is shorter than the length of the abutment rod. This length setting of the rocker arm and abutment rod creates a lever that requires less effort, reducing the space needed for movement of components including the actuator, rocker arm, rotating rod, and abutment rod.

[0010] Preferably, there are two or more abutment rods, symmetrically arranged on the rotating rod. This ensures even load distribution and avoids excessive local stress.

[0011] Preferably, the driver is hinged to the base.

[0012] Preferably, the driver is a linear motor, and the external input is electrical energy.

[0013] Preferably, the limiting hinge includes a first mounting plate, a second mounting plate, a hinge shaft, and a limiting plate. The hinge shaft includes two relatively rotating bodies, one of which is fixedly connected to the first mounting plate, and the other is fixedly connected to the second mounting plate. The limiting plate is fixedly connected to the hinge shaft and includes a first limiting plate and a second limiting plate. The angle between the first and second limiting plates is a limiting angle β. The first limiting plate is positioned on the movement path of the first mounting plate, and the second limiting plate is positioned on the movement path of the second mounting plate. The structure of the first mounting plate, the second mounting plate, and the hinge shaft enables relative rotation of the first and second back plates. The limiting plate achieves the function of limiting the angle β between the first and second back plates. The first and second limiting plates, which constitute the limiting plate, exist on the movement paths of the first and second mounting plates, respectively, such that the minimum angle between the first and second mounting plates is the limiting angle β. Similarly, the first back plate connected to the first mounting plate and the second back plate connected to the second mounting plate also have a minimum angle β.

[0014] Preferably, the surfaces of the first mounting plate and the second mounting plate are provided with a plurality of connection holes along their length. The connection holes enable the fixed connection between the first back plate and the first mounting plate, and the fixed connection between the second back plate and the second mounting plate.

[0015] Preferably, the length of the first back panel in the base length direction is greater than or equal to the length of the second back panel in the base length direction. This arrangement is ergonomic, as the length of the lower back section requiring support is less than that of the upper back section.

[0016] Compared with the prior art, the beneficial effects of this utility model are: (1) Through the segmented back panel design, combined with the limiting hinge, the back panel first forms an ergonomic support angle during the lifting process, and then the whole panel is lifted, which effectively improves the support of the mattress. (2) The driver achieves stable driving of the first back plate through the transmission structure of the rotating rod and the abutment rod, and the operation is smooth and reliable; (3) The structure of the limiting hinge is simple and reliable, and can accurately control the included angle between the first back plate and the second back plate; (4) The overall structure is reasonably designed and the components are closely matched, which can meet the needs of different users and improve the user experience.

[0030] Embodiment: See Figure 1 as shown, the electric bed structure for improving mattress support performance of the present utility model mainly includes a driver 1, a base 2, a thigh plate 3 and a back plate 4, wherein the back plate 4 is composed of a first back plate 5 and a second back plate 6. The driver 1, the thigh plate 3 and the back plate 4 are all arranged on the base. The second back plate 6 is hingedly connected with the thigh plate 3, the first back plate 5 and the second back plate 6 are rotatably connected through a limit hinge member 12, and the limit hinge member 12 makes the minimum included angle between the connected first back plate 5 and the second back plate 6 be a limit included angle β, and the limit included angle β is an obtuse angle. The driver drives the first back plate 5 to move.

[0031] See Figure 2 and Figure 3 as shown, in the actual use process, the first back plate 5 is driven by the driver 1, the first back plate 5 rotates relative to the second back plate 6, and after the angle between the two reaches the preset limit included angle β, the first back plate 5 and the second back plate 6 will rotate as a whole relative to the thigh plate 3. The mattress 21 above the back plate 4 and the thigh plate 3 has elasticity, and is forced by the back plate 4 and the thigh plate 3 to deform accordingly. To reach the same included angle X between the first back plate 5 and the thigh plate 3, the deformation of the mattress 21 in this solution is smaller than that in the solution where a single back plate is arranged to connect the thigh plate 3. In this solution, the included angle between the first back plate 5 and the second back plate 6 and the included angle between the second back plate 6 and the thigh plate 3 are both smaller than X, so the deformation degree of the mattress 21 at the corresponding position is smaller, which can better protect the mattress 21. Such a design can provide better support for the user's waist during the lifting process, while protecting the mattress 21 from excessive deformation or tearing.

[0032] The power of the driver 1 is transmitted to the first backboard 5 through a series of transmission structures. Specifically, the driver 1 is hingedly connected to the base 2, and this connection mode allows the driver 1 to freely adjust its angle during operation to adapt to position changes during the transmission process. The driver 1 includes a telescopic rod 10, the length of which can be adjusted by externally input electric energy. A free end of the telescopic rod 10 is hingedly connected with a rocker 11, and the other end of the rocker 11 is connected to a rotating rod 7. The rotating rod 7 is hingedly mounted on the base 2, and a plurality of abutting rods 8 are fixedly connected to the surface thereof. These abutting rods 8 are symmetrically distributed on the rotating rod 7 to ensure uniform load transmission. Abutting rollers 9 are mounted at the free end of each abutting rod 8, and these abutting rollers 9 are in direct contact with the first backboard 5 and drive the first backboard 5 through sliding friction. When the telescopic rod 10 of the driver 1 extends and retracts, the rocker 11 drives the rotating rod 7 to rotate around its axis, so that the abutting rods 8 and the abutting rollers 9 push the first backboard 5 to move.

[0033] In some embodiments, the driver 1 is connected with a hinge member. The hinge member has two rod bodies that can rotate relative to each other, and the two rod bodies are respectively connected to the driver 1 and the base 2. During the length change process of the telescopic rod 10, the angle between the driver 1 and the base 2 will change adaptively. Certainly, the hinged connection mode further includes arranging a bearing seat on the base 2, the driver 1 is fixedly connected to the inner ring of a bearing, and the outer ring of the bearing is rotatably connected to the bearing seat.

[0034] In some embodiments, the driver is an air cylinder, and kinetic energy input is realized by externally input air pressure or integrating an air pump in the bed body to provide high-pressure gas. In some embodiments, a rack and pinion can be used in cooperation to realize the length adjustment of the telescopic rod 10.

[0035] In some embodiments, the number of the abutting rods 8 is 2.

[0036] To optimize transmission efficiency and space utilization, the length of the rocker 11 is designed to be shorter than the length of the abutting rod 8, forming a force-reducing lever structure that reduces the movement space required for each component.

[0037] Reference Figure 4 to Figure 7As shown, the limiting hinge 12 mainly consists of a first mounting plate 13, a second mounting plate 14, a hinge shaft 15, and a limiting plate 16. The hinge shaft 15 includes two relatively rotating bodies 17, one of which is fixedly connected to the first mounting plate 13, and the other is fixedly connected to the second mounting plate 14. In some embodiments, the rotating body 17 is integrally formed with the first mounting plate 13, and the other rotating body 17 is integrally formed with the second mounting plate 14. The limiting plate 16 is fixedly mounted on the hinge shaft 15 and consists of a first limiting plate 18 and a second limiting plate 19. The included angle between them is the limiting angle β. The first limiting plate 18 is located on the movement path of the first mounting plate 13, and the second limiting plate 19 is located on the movement path of the second mounting plate 14. This design ensures that the minimum opening angle between the first back plate 5 and the second back plate 6 will not be less than the limiting angle β. As for the design of the limiting angle β, it can be set according to ergonomics. Its specific value is set according to the angle between the lower back and thighs of a person in a semi-sitting position. Those skilled in the art can set this value as needed, which is common knowledge to those skilled in the art.

[0038] The surfaces of the first mounting plate 13 and the second mounting plate 14 are provided with a plurality of connection holes 20 along the length direction. These connection holes 20 are used to realize the fixed connection between the first mounting plate 13 and the first back plate 5, and between the second mounting plate 14 and the second back plate 6. In addition, the length of the first back plate 5 in the length direction of the base 2 is designed to be greater than or equal to the length of the second back plate 6. This proportion is more ergonomic and can provide sufficient support for the upper back that requires more support.

[0039] This utility model's electric bed structure, which enhances mattress support, effectively solves the shortcomings of traditional electric beds in terms of support through a segmented back panel design and a unique transmission mechanism. It not only improves user comfort but also extends the lifespan of the mattress 21, and has broad application prospects.

[0040] The embodiments described above are merely preferred solutions of this utility model and are not intended to limit this utility model in any way. Other variations and modifications are possible without departing from the technical solutions described in the claims.
