[0025] The utility model is described in further detail below in conjunction with the accompanying drawings.

[0026] Those skilled in the art will readily come up with other embodiments of the utility model after considering the specification and practicing the utility model disclosed herein. This application is intended to cover any variation, use or adaptation of the utility model, which follows the general principles of the utility model and includes common knowledge or customary technical means in the art that are not disclosed in this disclosure. The specification and examples are to be regarded as exemplary only, and the true scope and spirit of the utility model are indicated by the claims.

[0027] The bed structure described in the utility model is mainly a bed board that is hinged to each other and is arranged on the bed frame. The bed board is lifted or flipped by a power device. The most common is an electric bed structure, which drives the bed board to flip by a driving motor; but the utility model can also be applied to structures that flip the bed board by other power structures. In addition, the table board of the utility model is not limited to the table top. This is just a description of its use to facilitate the description of the specification. Other auxiliary structures such as armrests, medical water hanging or storage structures, if applicable to the linkage structure of the utility model, can be replaced with the table board of the utility model with equivalent technical features.

[0028] like Figure 1 As shown, a bed structure with a table board assembly 4 includes: a first bed board 1 and a second bed board 2 that are hinged to each other, a bed frame 3 arranged below the first bed board 1 and the second bed board 2, and the second bed board 2 is fixedly connected to the bed frame 3; the table board assembly 4 is arranged on one side of the first bed board 1, and the table board assembly 4 is fixedly connected to the back of the first bed board 1 and is hingedly connected to one side of the bed frame 3; when the first bed board 1 is lifted, the first table board assembly 4 moves upward and forward, and when the first bed board 1 is lowered, the first table board mechanism moves downward and backward. In this embodiment, the first bed board 1 and the second bed board 2 form a hinged relationship, and at least the first bed board 1 can be flipped relative to the second bed board 2, and the power for flipping is not limited to electricity or human power. The table board assembly 4 is arranged on one side or both sides of the first bed board 1, and is connected to the back of the first bed board 1 and the frame of the bed frame 3 respectively. When the first bed board 1 is flipped up and down, the table board assembly 4 will rise and fall in conjunction with the movement trajectory of the first bed board 1, so that the table board assembly 4 and the shoulder joint of the user lying on the first bed board 1 are relatively stable; the user can use the table board assembly 4 more fully.

[0029] like Figure 1 , 2As shown, the table board assembly 4 includes a table top board 41, a first connecting rod mounting block 42, a second connecting rod mounting block 43, a linkage shaft 44, a shaft mounting seat 45 and a linkage connecting rod 46; the first connecting rod mounting block 42 is mounted on the back of the table top board 41 and close to one side of the first bed board 1; the second connecting rod mounting block 43 is arranged on the back of the table board, close to the middle area; the shaft mounting seat 45 is arranged on the back of the first bed board 1, one end of the linkage shaft 44 is arranged in the first connecting rod mounting block 42, and the other end is arranged in the shaft mounting seat 45; the first connecting rod mounting block 42 and the shaft mounting seat 45 are both provided with a first through hole 451 matching the linkage shaft 44; one end of the linkage connecting rod 46 is hinged to the second connecting rod mounting block 43, and the other end is hinged to the frame of the bed frame 3. In this embodiment, the table top 41, the linkage connecting rod 46 and the bed frame 3 of the table top assembly 4 are hinged to each other, and the linkage shaft 44 is fixedly connected to the back of the first bed board 1 along its length direction, extending one end of the outer side of the first bed board 1 and extending into the first connecting rod mounting block 42; the first connecting rod mounting block 42 is arranged on the back of the table top 41, close to the side of the first bed board 1, and can better accommodate one end of the linkage connecting rod 44. A second connecting rod mounting block 43 is arranged in the middle area of ​​the table top 41, which is hinged to one end of the linkage connecting rod 46, and the other end of the linkage connecting rod 46 is hinged to the frame of the bed frame 3, and a groove for the linkage connecting rod 46 to be hinged can be provided on the frame. If the center of the table top assembly 4 and the frame of the bed frame 3 are not in the same plane in the vertical direction, the linkage connecting rod 46 needs to be arc-shaped, gradually bending toward the side of the bed frame 3 from top to bottom until it is hinged to the side of the bed frame 3. Figure 3 As shown, when observed from the side of the bed, a stable parallelogram structure can be formed between the table top 41, the linkage rod 46, the bed frame 3 and the first bed board 1, thereby ensuring that the table top 41 can be synchronously linked when the first bed board 1 is raised or lowered, and the table top 41 maintains a horizontal direction and moves forward and upward or backward and downward.

[0030] like Figure 4As shown, further, a hollow groove 47 is provided on the back of the desktop panel 41 along the edge to the middle area, and the second connecting rod mounting block 43 adopts a base 49 matching the hollow groove 47, and the base 49 allows the second connecting rod mounting block 43 to slide in the hollow groove 47, and a stop block 48 is provided at the edge of the hollow groove 47 to block the hollow groove 47 and prevent the second connecting rod mounting block 43 from sliding out. In this embodiment, the desktop panel 41 is further improved, mainly by adopting a slidable second connecting rod mounting block 43, and a hollow groove 47 is provided from the front end to the middle area of ​​the desktop panel 41. A slideway is provided on the back of the desktop panel 41, and the cross-section of the hollow groove 47 is similar to a concave shape. A flat base 49 is provided under the second connecting rod mounting block 43, and the hollow groove 47 can be inserted. The second connecting rod mounting block 43 can slide in the slideway, and the open end is blocked by a stop block 48. When the first bed board 1 is laid flat, there is a risk of pinching hands between the first bed board 1 and the table board 41. Whether it is the gap between the first table board and the table board 41, or the gradually shrinking space under the table board 41 when the table board 41 is laid down, it is easy to cause limb pinching. Figure 5 As shown, in order to prevent possible risks of pinching, a slidable second connecting rod mounting block 43 is provided. By sliding the second connecting rod mounting block 43 in the table top panel 41, the height of one end of the table top panel 41 can be raised, thereby increasing the space under the table top panel 41, so that the pinched limbs can be pulled out or the risk of pinching of limbs can be reduced.

[0031] Furthermore, when the first bed board 1 is in a flat state, the centers of the first through hole 451 of the shaft mounting seat 45 and the first through hole 451 of the first connecting rod mounting block 42 are at the same height. In this embodiment, the linkage shaft 44 is arranged in the first through hole 451 of the shaft mounting seat 45 and the first connecting rod mounting block 42. When the bed board is flat, the first through hole 451 is at the same height, and the shape of the linkage shaft 44 does not need to be deformed, and a straight line is sufficient. In this way, when the table board 41 is lifted or lowered in a linkage manner, it can be ensured that the table board 41 can be better kept in a horizontal state.

[0032] Furthermore, the linkage shaft 44 is fixedly connected to the back of the first bed board 1 through a shaft mounting seat 45; the shaft mounting seat 45 is assembled from a male block 452 and a female block 453, and a semicircular groove 454 is formed between the male block 452 and the female block 453, and a plurality of annular notches 455 are also provided on the semicircular groove 454. Figure 6As shown, in this embodiment, a bracket mounting seat is installed on the back of the first bed board 1, which is composed of two male and female shell-like parts, with a semicircular groove 454 in the middle, which is used to engage with the first linkage shaft and be fixed on the table board to form a fixed rotating shaft. There are also a number of annular notches 455 in the middle of the semicircular groove 454, which are mainly used to store grease and grinding chips, reduce friction at the shaft, and facilitate the rotation of the table board when the backboard is raised, thereby reducing the power consumption of the driving force of the driving backboard.

[0033] Furthermore, the two sides of the rotating shaft mounting seat 45 are fixed with limit plates, and the linkage rotating shaft 44 is passed through the middle of the limit plates. In this embodiment, limit plates are installed on both sides of the rotating shaft mounting seat 45, and the limit plates adopt a sleeve with a large diameter and a small diameter combination. The small diameter is embedded in the semicircular groove 454, and the large diameter is against the side of the rotating shaft mounting seat 45 to prevent the linkage rotating shaft 44 from sliding left and right.

[0034] Furthermore, the desktop panel 41 can be configured as a storage drawer or storage slot to store items when used on the bed. In this embodiment, the plate shape of the desktop panel 41 can also be replaced with a box-shaped three-dimensional structure, and a shaft bracket and a linkage shaft 44 are provided on the lower panel of the storage drawer or storage slot.

[0035] Furthermore, a driving device is provided in the bed frame 3, and the driving device includes a driving motor 51 and a fixing bracket 52 fixing the back of the first bed board 1, and the driving motor 51 is used to drive the first bed board 1 to rise and fall. In this example, a fixing bracket 52 is provided on the back of the first bed board 1, and a driving motor 51 is provided to drive the bed board to flip, and the fixing bracket 52 is arranged below the linkage shaft 44 and will not interfere with the linkage shaft 44.

[0036] Furthermore, the shaft mounting base 45 is provided with at least three groups arranged side by side up and down on the back of the first bed board 1, so as to adjust the installation position of the table board assembly 4 according to the height of the user. In this example, multiple shaft mounting bases 45 can be provided on the bed back board, and table board assemblies 4 at different positions can be provided according to different user heights and usage habits. The table board assembly 4 can be conveniently and quickly installed by disassembling the male and female pieces.

[0037] Furthermore, the motion trajectory of the table board assembly 4 is to make an arc-shaped lifting motion with the hinge point of the first bed board 1 and the second bed board 2 as the center. In this embodiment, the table board assembly 4 relies on the linkage shaft 44 and the linkage pull rod to make the table top board 41 take the hinge point of the first bed board 1 and the second bed board 2 as the center. When the first bed board 1 is lifted, the table top board 41 can make an arc motion along the motion trajectory of the first bed board 1. The linkage between the table top board 41 and the first bed board 1 can make the table top board 41 move upward and forward or backward and downward.

[0038] The table board assembly of the utility model can realize the linkage effect with the electric bed board through a simple structure, reduce the corresponding manufacturing cost, and is easy to install. It can also prevent the risk of possible pinching when the user lies on the bed.

[0039] It should be understood that the present invention is not limited to the exact structure that has been described above and shown in the drawings, and that various modifications and changes may be made without departing from the scope thereof.
