Description

Technical Field

[0001] The present invention relates to the technical field of electric beds, in particular to an electric bed. Background Art

[0002] During the use of electric beds, the back board is generally flipped. Since the lumbar bed board is fixed, when the back board flips, the back board needs to be flipped along the joint between the back board and the lumbar bed board. This will cause a gap between the end of the back board and the wall, affecting the overall appearance and comfort of use. Some electric beds with a wall-mounted mechanism adopt a structure in which the upper and lower frames slide. However, due to the influence of various factors such as welding deformation and welding error, the wheels of the upper frame cannot be guaranteed to be on the same horizontal plane. When the vibrator is turned on, a single-sided wheel resonance phenomenon is prone to occur, generating noise; and when the upper and lower frame structures are installed, there are usually notches on the upper surface of the lower frame guide rail to facilitate the installation of the lower frame, but these notches affect the strength of the entire lower frame. Specifically, when the bed surface is subjected to severe impact, the notch of the lower frame guide rail plate begins to deform, affecting the inner width of the lower frame, and even causing the single-sided wheel of the upper frame to derail in severe cases, posing a safety hazard. To this end, we propose an electric bed with a wall-mounted structure to solve the above problems. Summary of the invention

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. This electric bed with a wall-leaning structure has a wall-leaning mechanism on the bed frame, and the wall-leaning mechanism drives the back board to rotate, so that the back board is close to the wall while rotating, replacing the upper and lower frame pulley rail structures of the traditional wall-leaning electric bed, thereby solving the problem of a gap between the back bed board and the wall when the back bed board is flipped along the joint between the back bed board and the waist bed board.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1 and Figure 2 The present invention provides an electric bed, comprising: a bed board 1 and a bed frame 2, wherein the bed board 1 and a wall-leaving mechanism are arranged on the bed frame 2; wherein, the bed board 1 comprises: a back board 11, wherein the wall-leaving mechanism drives the back board 11 to flip relative to the bed frame 2 and simultaneously drives the back board 11 to move toward the head A; the wall-leaving mechanism comprises: a connecting rod assembly 3 and a driver 4, wherein the tail B of the back board 11 is connected to the head A of the bed frame 2 through the connecting rod assembly 3, the head A of the driver 4 is hinged to the bed frame 2, and the tail B of the driver 4 is hinged to the connecting rod assembly 3.

[0031] When the wall-supporting mechanism drives the back plate 11 to flip upward, it also drives the back plate 11 to move toward its free end side, that is, toward the head A. By adopting the wall-supporting mechanism to control the flipping of the back plate 11 and the movement toward the head A, the back plate 11 is close to the head A while flipping, thereby solving the problem of the increased horizontal distance between the back plate 11 and the head A when it is square after flipping upward, improving the aesthetics and visual distance during use, allowing the user to watch TV at the maximum visual distance when lying down, and improving comfort; compared with the traditional technical solution, this solution supports the back plate 11 through the connecting rod assembly 3, and the connecting rod assembly 3 is also supported by the driver 4, so the deformation of the back plate 11 is smaller; the connecting rod assembly 3 replaces the upper frame in the traditional wall-supporting electric bed, and the material consumption is more economical; in the product process, the proportion of welded parts in the manufacturing process is reduced, the proportion of stamped parts is increased, the parts are integrally formed, the process is simple, the parts are more precise, and the assembly difficulty is lower. The overall structure reduces the manufacturing cost.

[0032] Furthermore, the connecting rod assembly 3 includes: a connecting rod fixing seat 31, a connecting rod 32, a connecting rod bracket 33 and a flip bracket 34; wherein the connecting rod fixing seat 31 is fixed to the tail B of the back plate 11; the length of the connecting rod bracket 33 is greater than that of the connecting rod 32, and both ends of the connecting rod 32 and the connecting rod bracket 33 are respectively hinged to the connecting rod fixing seat 31 and the head A of the bed frame 2 and form an "eight" shape structure; the head A of the flip bracket 34 slides against the back plate 11, and the tail B of the flip bracket 34 is hinged to the connecting rod bracket 33 or the bed frame 2; the tail B of the driver 4 is hinged to the flip bracket 34.

[0033] There are two sets of connecting rod fixing seats 31 symmetrically arranged on both sides of the back plate 11 . When the driver 4 is working, the length of the driver 4 increases, thereby pushing the flip bracket 34 to make a circular motion around the connection point between it and the connecting rod bracket 33, driving the back plate 11 to flip upward. Since the connecting rod fixing seat 31 is connected to the connecting rod 32 and the connecting rod bracket 33, the back plate 11 rotates clockwise around the connection point between the connecting rod bracket 33 and the connecting rod fixing seat 31, and the back plate 11 forms an angle with the horizontal plane. Since the connecting rod bracket 33 makes a circular motion, the back plate 11 moves forward as a whole. At this time, the back plate 11 moves against the wall as a whole, and the back is lifted, thereby realizing the wall-keeping operation. A more reliable direct connection method is used to replace the original upper and lower frame pulley rail structure, and the assembly is tighter. Compared with the upper and lower frames, the gap is smaller and the deformation is lower, which helps to improve the reliability of the electric bed; since the driver 4 is installed more forward, the size of the driver 4 installation is increased, and the movement trajectory of the driver 4 becomes a circular motion. Each stroke of the driver 4 extending has a more obvious effect on the lifting and movement of the back plate 11; the distance from the wall increases, and the angle of the back plate 11 rises.

[0034] Furthermore, in terms of motor load, the upper and lower frames of the traditional wall-mounted electric bed are rotated by directly connecting the motor bracket on the bed frame. The motor's lever arm tends to gradually decrease during the movement, while the lever arm of the driver 4 of this solution is in a continuous increasing process during the movement. Throughout the entire movement process, the connecting rod assembly 3 has a smaller load on the driver 4, the driver 4 has a longer service life, and the probability of after-sales maintenance is reduced.

[0035] Furthermore, the connecting rod fixing seat 31 includes: a first connecting rod fixing seat 311 and a first connecting rod fixing seat 312, the first connecting rod fixing seat 311 and the first connecting rod fixing seat 312 are arranged in parallel with each other, the tail B of the first connecting rod fixing seat 311 is hinged to the tail B of the connecting rod 32, and the head A of the first connecting rod fixing seat 312 is hinged to the tail B of the connecting rod bracket 33.

[0036] The connecting rod fixing seat 31 is connected to the connecting rod 32 installed on the bed frame 2. At this time, the back panel 11 rotates clockwise around the connection point between the connecting rod bracket 33 and the second connecting rod fixing seat 312. The back panel 11 forms an angle with the horizontal plane. Since the connecting rod bracket 33 makes a circular motion, the back panel 11 moves forward as a whole. At this time, the back panel 11 moves as a whole to lean against the wall and lift the back, thereby realizing the wall-leaning operation and avoiding a series of problems caused by the sliding connection of the upper and lower frames.

[0037] Furthermore, the flip bracket 34 is in an “H”-shaped structure, a head portion A of the flip bracket 34 is provided with a roller that abuts against the back plate 11 , and a head portion A of the driver 4 is hinged to a middle crossbar of the flip bracket 34 .

[0038] This technical solution can improve the force between the flip bracket 34 and the driver 4 and enhance the stability of the wall-resting mechanism.

[0039] Furthermore, the position where the head portion A of the flip bracket 34 and the back plate 11 are slidably abutted against each other is located on the left side of the connecting rod assembly 3 along the direction from the head portion A to the tail portion B.

[0040] The position where the head A of the flip bracket 34 slides against the back plate 11 is best maintained on the left side of the connecting rod assembly, that is, on the left side of the connecting rod assembly 3 along the direction from the head A to the tail B. At this time, the force arm is most reasonable, the flipping process of the back plate 11 is more stable, the load on the driver 4 is relatively small, and the product service life is longer.

[0041] Furthermore, the bed board 1 also includes: a lower body board, and the back board 11 and the lower body board are sequentially arranged on the bed frame 2. Specifically, the lower body board includes: an arm board 12, a fixed board 13, a leg board 14 and a foot board 15, and the bed frame 2 includes: a front frame 21 and a rear frame 22; wherein, the back board 11 and the arm board 12 are sequentially arranged on the front frame 21, the arm board 12 is fixedly connected to the tail B of the front frame 21, and the tail B of the driver 4 is hinged to the tail B of the front frame 21; the fixed board 13, the leg board 14 and the foot board 15 are hingedly arranged on the rear frame 22 in sequence, and the fixed board 13 is fixedly connected to the head A of the rear frame 22; the front frame 21 and the rear frame 22 are foldably connected.

[0042] Further, see Figure 1 The electric bed with a wall-supporting structure also includes a leg flipping mechanism, which drives the leg plate 14 to flip relative to the rear frame 22. The leg flipping mechanism adopts various driving methods in the prior art and will not be described in detail. The leg flipping mechanism drives the leg plate to flip relative to the fixed plate to lift the legs, reduce the pressure on the legs of the human body, make the bed surface closer to the human body curve, and give the user a better sleeping experience.

[0043] Further, see Figure 1 and Figure 2 The electric bed with a wall-supporting structure also includes a foot connecting rod 5, and both ends of the foot connecting rod 5 are hinged to the rear frame 22 and the foot plate 15 respectively.

[0044] When the leg plate 14 changes in motion, the foot plate 15 is hinged with the leg plate 14 under the action of the pulling force of the leg plate 14 and the foot connecting rod 5, and the foot plate 15 is turned upward along with the tail B of the leg plate 14, and the foot plate is lifted as a whole. If the human arm is on the arm plate 12 and the fixed plate 13, the back is leaning on the back plate 11, and the knee joint is above the junction of the leg plate 14 and the foot plate 15, the change of the bed board can better adapt to the changing curve of the human body, avoiding the loss of support of the foot after the leg is turned over. This solution can realize the deformation of the leg plate 14 and the foot plate 15 only through a leg turning mechanism, saving the cost of the electric bed.

[0045] Furthermore, the driver 4 is a removable straight-rod motor.

[0046] The removable straight-rod motor only provides thrust for pushing, and does not generate pulling force. The corresponding part only relies on its own gravity to descend, which is safer and less likely to pinch the user.

[0047] Furthermore, the lengths of the front frame 21 and the rear frame 22 along the direction from the front portion A to the rear portion B are equal.

[0048] The middle of the bed frame 2 is the bisection point, and the driver 4 is arranged on one side of the bisection point of the bed frame 2. This technical solution can realize the integration of the wall-leaning and folding functions. The product can be folded without removing the wall-leaning mechanism, reducing transportation costs and improving the adaptability range of the wall-leaning mechanism.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
