Description

Technical Field

[0001] This utility model relates to the field of bed accessories technology, specifically to a soft bed accessory frame. Background Technology

[0002] Traditional upholstered bed frame systems have several shortcomings in use. Existing frame designs often have a simplistic cushioning structure, making it difficult to effectively address uneven pressure on users of different weights or mattresses, resulting in poor support and impacting sleep comfort. Furthermore, some frame systems have inadequate limiting mechanisms in their elastic components under pressure, leading to excessive displacement or structural wobbling. This not only reduces the frame's stability but can also generate noise, further affecting the user experience. In addition, traditional frame systems often use fixed connections for cushioning and support, lacking flexible linkage mechanisms and the ability to adaptively adjust to actual pressure. This can lead to structural fatigue over long-term use, shortening the lifespan of the mattress. Therefore, we propose a new upholstered bed accessory frame to address these issues. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a soft bed accessory frame, which solves the problems mentioned in the background art.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a soft bed accessory frame, including a frame, a buffer structure is provided in the frame, a groove is provided on the frame, a U-shaped plate is fixedly installed in the groove through a protruding block that is movably connected, and rectangular grooves are provided on the inner walls of the left and right sides of the frame. The buffer structure includes two support plates, with both ends of the support plates fixedly installed on the inner wall of the frame. Several limiting grooves are opened on the upper surface of the two support plates, and elastic components are movably installed in the several limiting grooves. A slat frame is movably installed on the elastic component, and a protruding plate is fixedly installed on the slat frame. The protruding plate is used to contact or cooperate with other components such as a mattress. The elastic component includes an arc-shaped elastic sheet, with limit blocks fixedly installed at both ends of the arc-shaped elastic sheet. The arc-shaped elastic sheet and the limit blocks are movably installed in a limit groove, which is used to limit the range of movement of the elastic component. The frame is movably abutted against the arc-shaped elastic sheet through a U-shaped plate, and the frame can slide left and right along the U-shaped plate.

[0005] Furthermore, limit post one and limit post two are fixedly installed at both ends of the frame, and buffer springs are sleeved on one end of the frame to provide buffering force.

[0006] Furthermore, the lower surface of the shaped plate is provided with several U-shaped holes, which are used to pass through the limiting post. The limiting post slides in conjunction with the U-shaped hole, allowing the limiting post to move up and down within the U-shaped hole. One end of the buffer spring is fixed inside the shaped plate, and the other end abuts against the bottom of the frame, forming a buffer connection of "shaped plate-spring-frame".

[0007] Furthermore, the lower surface of the frame is provided with several U-shaped holes, and the several U-shaped holes are connected to the rectangular groove. Several fixed cylinders are fixedly installed on the lower surface of the frame. A resistance spring is movably installed inside the fixed cylinder. One end of the resistance spring is fixedly connected to the inner wall of the fixed cylinder, and the other end is movably abutted against the bottom of the limiting post, forming a support structure of "fixed cylinder-spring-limiting post". One end of the buffer spring is fixed in the rectangular groove, and the other end abuts against the bottom of the frame.

[0008] Furthermore, the openings of the first U-shaped hole and the second U-shaped hole face the left and right sides of the support plate, and the rectangular groove is connected to the fixed cylinder.

[0009] Furthermore, the length of the first limiting post is less than the height inside the molded plate, so as to limit the first post from exceeding the accommodating range of the molded plate when sliding.

[0010] The beneficial effects of this utility model are: 1. The slatted frame of this upholstered bed accessory features a buffer structure consisting of a support plate, a limiting groove, an arc-shaped elastic sheet, and a U-shaped plate. When the slatted frame is under pressure, the arc-shaped elastic sheet undergoes arc deformation under the pressure of the slatted frame. The impact force is dispersed to the support plate through the U-shaped plate, and the limiting groove restricts excessive displacement of the elastic sheet, ensuring buffering stability. When the mattress is subjected to uneven force in certain areas, the slatted frame can slide left and right along the U-shaped plate, causing the limiting post to move laterally within the U-shaped hole, allowing the deformation area of ​​the arc-shaped elastic sheet to self-adaptively adjust and balance the force on each part.

[0011] 2. The slatted frame of this upholstered bed accessory limits the movement range of the elastic components through limiting grooves to prevent excessive displacement of the arc-shaped elastic sheet; the sliding fit between limiting post one and U-shaped hole one, and the abutting structure between limiting post two and fixed cylinder, allow the slatted frame to make buffered movements in the vertical direction, while preventing lateral swaying through geometric limiting. At the same time, the slatted frame can slide left and right along the U-shaped plate through movable abutting with the arc-shaped elastic sheet, and can achieve adaptive adjustment when the force is uneven, ensuring the stability of the overall support structure.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] Please see Figures 1-7 A soft bed accessory frame includes a frame 1, a buffer structure 2 inside the frame 1, and a groove 3 on the frame 1. A U-shaped plate 4 is fixedly installed in the groove 3 through a movable protrusion. The frame 1, U-shaped plate 4, buffer structure 2 and other components are modularly assembled, and quick installation is achieved through movable connection structures such as protrusion 26 and rectangular groove 6. When a certain elastic component (such as arc-shaped elastic sheet 231, buffer spring 29) is fatigued and damaged, the individual component can be directly disassembled and replaced without disassembling the entire frame 25, reducing maintenance costs and operation difficulty; rectangular grooves 6 are opened on the inner walls of the left and right sides of the frame 1. The cushioning structure 2 includes two support plates 21. The two ends of the support plates 21 are fixedly installed on the inner wall of the frame 1. Several limiting grooves 22 are opened on the upper surface of the two support plates 21. Elastic components are movably installed in the several limiting grooves 22. A slat frame 25 is movably installed on the elastic components. A protruding plate 26 is fixedly installed on the slat frame 25. The protruding plate 26 is used to contact or cooperate with other components such as a mattress. The elastic component includes an arc-shaped elastic sheet 231, with limit blocks 232 fixedly installed at both ends of the arc-shaped elastic sheet 231. The arc-shaped elastic sheet 231 and the limit blocks 232 are movably installed in the limit groove 22, which is used to limit the range of movement of the elastic component. The frame 25 is movably abutted against the arc-shaped elastic sheet 231 through a U-shaped plate 24, and the frame 25 can slide left and right along the U-shaped plate 24.

[0017] In this embodiment, the movement range of the elastic component is limited by the limiting groove 22 to prevent the arc-shaped elastic sheet 231 from deviating excessively; the sliding fit between the limiting post 27 and the U-shaped hole 5, and the abutting structure between the limiting post 28 and the fixed cylinder 8, allow the frame 25 to perform buffering movement in the vertical direction, and prevent its lateral swaying through geometric limiting. At the same time, the frame 25 can slide left and right along the U-shaped plate 24 through the movable abutting of the arc-shaped elastic sheet 231, and can achieve adaptive adjustment when the force is uneven, so as to ensure the stability of the overall support structure.

[0018] Reference Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, limit post 1 27 and limit post 28 are fixedly installed at both ends of the frame 25, respectively. A buffer spring 29 is sleeved on one end of the frame 25 to provide buffer force.

[0019] In this embodiment, by setting a buffer structure 2 consisting of a support plate 21, a limiting groove 22, an arc-shaped elastic sheet 231, and a U-shaped plate 24 within the frame 1, when the frame 25 is subjected to pressure, the deformation of the arc-shaped elastic sheet 231 can absorb the initial impact force, and the buffer springs 29 (the buffer springs 29 between the limiting post 27 and the U-shaped plate 4, and between the limiting post 28 and the rectangular groove 6) further provide continuous elastic support, forming a multi-level shock absorption system of "elastic sheet + double springs", which effectively reduces the vibration transmitted by the mattress and improves the comfort during sleep.

[0020] Reference Figure 5 As shown, the lower surface of the return plate 4 has several U-shaped holes 5, which are used to pass through the limiting post 27. The limiting post 27 slides in the U-shaped hole 5, allowing the limiting post 27 to move up and down within the U-shaped hole 5. One end of the buffer spring 29 is fixed inside the return plate 4, and the other end abuts against the bottom of the frame 25, forming a buffer connection of "return plate-spring-frame".

[0021] Reference Figure 6 and Figure 7As shown, the lower surface of the frame 1 has several U-shaped holes 7, and the several U-shaped holes 7 are connected to the rectangular groove 6. Several fixed cylinders 8 are fixedly installed on the lower surface of the frame 1. A resisting spring 9 is movably installed in the fixed cylinder 8. One end of the resisting spring 9 is fixedly connected to the inner wall of the fixed cylinder 8, and the other end is movably abutting against the bottom of the limiting post 28, forming a support structure of "fixed cylinder-spring-limiting post 2". One end of the buffer spring 29 is fixed in the rectangular groove 6, and the other end abuts against the bottom of the frame 25.

[0022] In this embodiment, the dual support structure of "U-shaped plate 4-buffer spring 29-slat frame 25" and "fixed cylinder 8-resistance spring 9-limiting column 28" ensures that when the slat frame 25 is subjected to pressure, the buffer springs 29 at both ends are simultaneously stressed, distributing the pressure evenly to various parts of the frame 1. The opening orientation of U-shaped hole 1 5 and U-shaped hole 2 7, combined with the connecting structure of rectangular groove 6 and fixed cylinder 8, forms a through force transmission path, avoiding local stress concentration and extending the service life of the slat frame 25.

[0023] Reference Figures 5-7 As shown, the openings of U-shaped hole 5 and U-shaped hole 7 face the left and right sides of the support plate 21 to ensure that there is no interference when the limiting column moves laterally; the rectangular groove 6 is connected to the fixed cylinder 8.

[0024] Reference Figure 5 As shown, the length of the limiting post 27 is less than the height inside the return plate 4, so as to limit the limiting post 27 from going beyond the accommodation range of the return plate 4 when sliding.

[0025] In this embodiment, when a certain elastic component (such as the arc-shaped elastic sheet 231 or the buffer spring 29) suffers fatigue damage, the frame 25 is lifted upwards. The limiting post 27 at one end of the frame 25 disengages from the interior of the U-shaped hole 5, and at the same time, the limiting post 28 also disengages from the interior of the U-shaped hole 7. The frame 25 is then moved to one side of the molded plate 4, so that the frame 25 located at the end of the limiting post 28 disengages from the interior of the rectangular groove 6. Then, the frame 25 is pulled out from the molded plate 4, allowing the individual component to be disassembled and replaced directly without disassembling the entire frame 25, thus reducing maintenance costs and operational difficulty.

[0026] During use, when the mattress is pressed down, the arc-shaped elastic sheet 231 undergoes arc-shaped deformation under the pressure of the frame 25. The impact force is dispersed to the support plate 21 through the U-shaped plate 24, and the limiting groove 22 restricts excessive displacement of the elastic sheet, ensuring cushioning stability. When the mattress experiences uneven pressure in certain areas, the frame 25 can slide left and right along the U-shaped plate 24, causing the limiting post 27 to move laterally within the U-shaped hole 5, allowing the deformation area of ​​the arc-shaped elastic sheet 231 to adaptively adjust and balance the force on each part. At the same time, the two ends of the frame 25 will cause the limiting post 27 and the limiting post 28 to move downward. The limiting post 27 slides within the U-shaped hole 5, compressing the cushioning spring 29 in the retaining plate 4; the limiting post 28 compresses the cushioning spring 29 in the rectangular groove 6, while the bottom resistance spring 9 is compressed, forming triple elastic cushioning. When the pressure is released, the resistance spring 9 pushes the limiting post 28 upward. The rectangular groove 6 and the buffer spring 29 in the return plate 4 are moved and reset synchronously, driving the frame 25 to rise. The arc-shaped elastic sheet 231 recovers its deformation. The U-shaped plate 24 assists the frame 25 to return to its position, reducing vibration rebound. The length of the first limiting post 27 is less than the height inside the return plate 4. When a certain elastic component (such as the arc-shaped elastic sheet 231 or the buffer spring 29) is fatigued, the frame 25 is lifted upward. The first limiting post 27 at one end of the frame 25 disengages from the inside of the U-shaped hole 5. At the same time, the second limiting post 28 also disengages from the inside of the U-shaped hole 7, moving the frame 25 to one side of the return plate 4. This causes the frame 25 located at the end of the second limiting post 28 to disengage from the inside of the rectangular groove 6. Then, the frame 25 is pulled out from the return plate 4. Individual components can be directly disassembled and replaced without disassembling the entire frame 25, reducing maintenance costs and operational difficulty.
