Description

Technical Field

[0001] The utility model relates to a bed structure, in particular to a bed structure with a table board component. Background Art

[0002] As the popularity of electric beds increases, more and more users begin to need to use the auxiliary functions of electric beds, such as setting a table on one side of the electric bed so that it is convenient to use a computer or eat food when it is lifted up. However, the table or armrest structures on both sides of the current electric beds are relatively fixed to the bed frame. In the electric bed, when the bed board is lifted or lowered by the driving device, the table or armrest structure cannot be lifted or lowered with the bed board. When getting up, the user cannot fully use the table or armrest structure.

[0003] In the patent application number: 202110961422.5, the application date: 2021.08.20, the patent name: an emergency acupuncture auxiliary device; it shows an emergency acupuncture auxiliary device linked to the bed board, which is composed of a parallelogram-like structure through a railing 2, a support arm 3, a support needle assembly 5, and an adjustment rod 4, which is used to link with the back bed board. The adjustment rod is pushed up and down by a linkage rod, and an adjustment block and an adjustment frame are provided on the adjustment rod for the horizontal height of the support needle assembly separately. The problem with this structure is that the horizontal linkage effect of the support needle assembly is not good. When the linkage rod pushes the adjustment rod to rise, when the back bed board is lifted to a higher angle, the support needle assembly cannot remain horizontal, and the rear end will tilt up. The support needle assembly needs to be adjusted to a horizontal level through the adjustment block and the adjustment frame. The linkage effect is relatively general and the operation is relatively complicated. Utility Model Content

[0028] Embodiment 1

[0029] 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 slidably 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 raised, 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 drive. 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 back of the second bed board 2 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.

[0030] like Figure 1 , 2As shown, the table top assembly 4 includes a table top plate 41, a first connecting rod connecting base, a first linkage connecting rod 43, a second connecting rod base 44, a second linkage connecting rod 45, a linkage rotating shaft 46 and a rotating shaft mounting seat 47; the first connecting rod base 42 and the second connecting rod base 44 are arranged below the table top plate 41, the first linkage connecting rod 43 and the second linkage connecting rod 45 are in an "L" shape, and the first linkage connecting rod 43 and the second linkage connecting rod 45 are in an "L" shape. One end of 45 is hinged to the first link base 42 and the second link base 44 respectively, and the other end is hinged to one side of the bed frame 3 respectively; one end of the linkage shaft 46 is slidably connected with the first linkage link 43 in the vertical direction, and the other end of the linkage shaft 46 is fixedly connected to the back of the first bed board 1 through the shaft mounting seat 47. When the first bed board 1 is lifted or lowered, the linkage shaft 46 slides on the first linkage link 43, thereby driving the table board assembly 4 to maintain horizontal linkage during the lifting process. In this embodiment, the table board 41, the first linkage link 43, the second linkage link 45 of the table board assembly 4 and the bed frame 3 form a parallelogram mechanism. The back of the first bed board 1 is slidably connected with the first linkage link 43 in the vertical direction through the linkage shaft 46. When the back board rises, it pushes the parallelogram mechanism to rise. Due to the relative motion relationship between the table board and the link, the linkage shaft 46 can slide along the vertical direction of the first linkage link 43 or the first bed board 1. In the initial state, the upper surface of the table top assembly 4 is horizontal, which is used to prevent objects from being placed. Sometimes there are some protrusions or depressions, which are mainly used to better place cups, mobile phones, controllers, etc.

[0031] like Figure 3 As shown, in this embodiment, a quadrilateral structure is formed by the desktop 41, the first linkage link 43, the second linkage link 45 and the center line of the bed frame 3. When the desktop 41 is raised, the vertical parts of the first linkage link 43 and the second linkage link 45 are always kept horizontal, and their lengths are equal (similar to each other in a parallelogram), and the two are parallel (similar to each other in a parallelogram). When the parallelogram mechanism moves, the angles between the first linkage link 43 and the second linkage link 45 and the horizontal plane remain the same, that is, the second side of the parallelogram moves in translation but not in rotation. Since the desktop assembly 4 is a rigid structure, the horizontal plane angle of the desktop remains unchanged and remains horizontal. Its working principle is: construct a parallelogram mechanism so that the angle between the desktop 41 and the linkage link remains unchanged, that is, the desktop 41 maintains the initial angle state. In this structure, the table top 41 is initially in a horizontal state, the first linkage link 43 and the second linkage link 45 always remain horizontal, and the table top 41 rises as the first bed board 1 rises, and its angle remains unchanged.

[0032] Furthermore, a sliding sleeve 48 is provided at one end of the linkage shaft 46. The sliding sleeve 48 is provided with a slot hole of a size matching the first linkage link 43, and is sleeved on the vertical part of the first linkage link 43 to slide along the vertical direction of the first linkage link 43. In the first embodiment, one end of the linkage shaft 46 and the first linkage link 43 adopt a sliding sleeve 48 provided at the end of the linkage shaft 46, which is sleeved on the vertical part of the first linkage link 43; the other end of the linkage shaft 46 is fixed to the back of the first bed board 1. When the first bed board 1 is raised or lowered, the linkage shaft 46 slides on the first linkage link 43, and the friction between the sliding sleeve 48 and the first linkage link 43 is used to drive the entire table board assembly 4 to be raised or lowered synchronously. The structure is simpler than the prior art, and when the first bed board 1 is linked, the upper surface of the table board 41 always maintains a horizontal angle and does not tilt, and the linkage effect is better.

[0033] like Figure 1 As shown, further, the linkage shaft 46 is fixedly connected to the back of the first bed board 1 through a shaft mounting seat 47; the shaft mounting seat 47 is assembled from a male block 471 and a female block 472, and a semicircular groove 473 is formed between the male block 471 and the female block 472, and a plurality of annular notches 474 are also provided on the semicircular groove 473. Figure 5 As 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 473 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 474 in the middle of the semicircular groove 473, 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.

[0034] Furthermore, the two sides of the rotating shaft mounting seat 47 are fixedly provided with limit plates 49, and the linkage rotating shaft 46 is passed through the middle of the limit plates 49. In this embodiment, the limit plates 49 are installed on both sides of the rotating shaft mounting seat 47, and the limit plates 49 adopt a sleeve with a large diameter and a small diameter combination, the small diameter is embedded in the semicircular groove 473, and the large diameter is against the side of the rotating shaft mounting seat 47, so as to prevent the linkage rotating shaft 46 from sliding left and right.

[0035] 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 rotating shaft bracket and a linkage rotating shaft 46 are provided on the lower panel of the storage drawer or storage slot.

[0036] Further, a driving device is provided inside the bed frame 3. The driving device includes a driving motor 50 and a fixing bracket 51 fixed to the back of the first bed board 1. The driving motor 50 is used to drive the first bed board 1 to lift and lower. In this embodiment, a fixing bracket 51 is provided on the back of the first bed board 1, and a driving motor 50 is equipped to drive the bed board to flip. The fixing bracket 51 is arranged below the linkage rotating shaft 46 and will not interfere with the linkage rotating shaft 46.

[0037] Further, at least three groups of the rotating shaft mounting seats 47 are arranged side by side up and down on the back of the first bed board 1 to facilitate adjusting the mounting position of the table board assembly 4 according to the user's height. In this embodiment, a plurality of rotating shaft mounting seats 47 can be provided on the bed backboard. According to different user heights and usage habits, the table board assemblies 4 at different positions can be set. By disassembling the male and female parts, the table board assembly 4 can be installed conveniently and quickly.

[0038] Further, the movement track of the table board assembly 4 is an arc-shaped lifting movement with the hinge point of the first bed board 1 and the second bed board 2 as the center of the circle. In this embodiment, the table board assembly 4 relies on the linkage rotating shaft 46 and the linkage pull rod, so that the table board 41 can take the hinge point of the first bed board 1 and the second bed board 2 as the center of the circle. When the first bed board 1 is lifted, the table board 41 can move in an arc along the movement track of the first bed board 1. The linkage between the table board 41 and the first bed board 1 is realized, and the table board 41 can move upward and forward or backward and downward.

[0039] Embodiment 2

[0040] As Figure 4 shown, in Embodiment 2, the same bed body structure as that in Embodiment 1 is adopted. The main difference lies in the way of the sliding connection between the linkage rotating shaft 46 and the first linkage rod 43. The rotating shaft mounting seat 47 adopts a "U"-shaped slide rail 6, with the opening facing the table board assembly 4. One side of the rotating shaft installation is fixedly connected to the back of the first bed board 1; one end of the linkage rotating shaft 46 is slidably connected to the rotating shaft mounting seat 47, and the other end is fixedly connected to the first linkage rod 43. In this embodiment, the linkage rotating shaft 46 and the first linkage rod 43 are relatively fixed. By providing a "U"-shaped connecting piece on the back of the first bed board 1, the rotating shaft mounting seat 47 is set in the form of a slide rail, and a slider is provided at one end of the linkage rotating shaft 46 connected thereto. The slider can slide up and down in the rotating shaft mounting seat 47 in the form of a slide rail. Thus, with the lifting or lowering of the first bed board 1, the table board 41 assembly can be driven to move horizontally upward and forward or horizontally downward and backward, and better linkage between the table board assembly 4 and the first bed board 1 can also be realized.

[0041] It should be understood that the present invention is not limited to the exact structure already described and shown in the drawings, and various modifications and changes can be made without departing from its scope.
