Description

Technical Field

[0001] The invention relates to the technical field of hidden furniture, in particular to a flip connection structure of a hidden bed. Background Art

[0002] Now, with the increase in population, housing prices are getting higher and higher, and apartment types are getting smaller and smaller, and people have higher and higher requirements for the utilization and multi-functionality of housing space.

[0003] The invisible bed is also called a wall bed or a flip bed; when not being used for sleeping, the invisible bed looks like a wardrobe and can be turned into a desk or a sofa; when you need to sleep, just flip the bed down and the bed can be used for sleeping; the invisible bed has a compact structure, diverse functions, and reasonable use of space, making it suitable for modern times.

[0004] The existing invisible bed structure, such as the Chinese utility model patent with authorization announcement number CN208822078U, discloses a flip-up invisible bed, which includes a main frame and a bed frame, wherein the main frame is provided with a receiving groove, and the internal space of the receiving groove forms a receiving space; the bed frame is directly and / or indirectly mounted on the main frame through a hinge, and the bed frame can be switched between an unfolded state and a stowed state by rotating relative to the main frame: in the stowed state, the bed frame is located in the receiving space as a whole; in the unfolded state, the bed frame reaches outside the receiving space; the bed frame includes a bed frame and a flat bottom plate; the flat bottom plates are all fastened to the bed frame, and in the unfolded state, the flat bottom plate is located at the lower end surface of the bed frame. This invisible bed can be switched between the unfolded state and the stowed state. In actual application, the bed can be flipped and hidden during the day to save space.

[0005] However, when the bed board is flipping, the change in its opening angle affects the required supporting force. The closer it is to the vertical state, the smaller the pushing force is. On the contrary, the closer it is to the horizontal state, the heavier the weight is, resulting in a faster falling speed. The above-mentioned invisible bed is supported by a single pneumatic rod. The supporting force for balancing the weight of the bed board is provided by the pneumatic rod, and the supporting force of the pneumatic rod on the bed board is constant. If it is necessary to open the bed board more conveniently, the supporting force of the pneumatic rod is relatively small. Then, when the bed board moves to the horizontal state, the supporting force required by the hand gradually increases, which may cause the bed board to fall sharply and may injure people or the ground. If the pneumatic rod is required to provide a larger supporting force when the bed board is close to the horizontal state, a pneumatic rod with a large supporting force is required. However, when the bed board is folded, the speed of the bed board will be very fast when it is close to the vertical state, and there is a possibility of the hand being pinched. Moreover, a larger pulling force is required when opening the bed board, which is very inconvenient to use. Summary of the invention

[0006] In view of the deficiencies in the prior art, an object of the present invention is to provide a flip connection structure for an invisible bed, which can adjust the supporting force of the bed board during the opening process to facilitate opening and folding.

[0007] The above technical purpose of the present invention is achieved through the following technical solutions: a flip connection structure of an invisible bed, including a bed frame and a bed board rotatably connected to the bed frame, side panels are provided on both sides of the bed frame, and a rotating push plate connected to the bed board is rotatably connected on the side panels, and at least two telescopic balancing parts that make the bed board have a tendency to retract are provided between the rotating push plate on each side and the corresponding side panel, and the working number of the telescopic balancing parts on each side is positively correlated with the opening angle of the bed board.

[0008] By adopting the above technical solution, when the bed board is in the process of opening, the rotating push plate will be linked with the bed board and rotate. At this time, the telescopic balance member will hinder the bed board when it rotates, thereby providing support. As the opening angle of the bed board gradually increases, the total number of telescopic balance members working will gradually increase, thereby increasing the supporting force for the bed board. When the bed board moves to a horizontal state, the number of telescopic balance members working reaches a maximum value, reducing the supporting force required for the hand, and the bed board will not drop rapidly in the open state. At the same time, when it is folded, the number of telescopic balance members working will gradually decrease. When folded into the bed frame, the number of telescopic balance members working reaches a minimum value, and the bed board can be slowly folded to reduce the possibility of pinching the hand. At the same time, it is also more convenient to open the bed board, and the supporting force for the bed board can be adjusted during the opening process, which is convenient for opening and folding.

[0009] In a preferred example, the present invention can be further configured as follows: the telescopic balance member is a follower pneumatic rod, and multiple follower pneumatic rods are arranged in sequence outward from the rotation center point of the rotating push plate, and the two ends of the follower pneumatic rod are respectively hinged to the rotating push plate and the side plate.

[0010] By adopting the above technical solution, when the bed board rotates, the rotating push plate will also rotate accordingly. During the rotation, the distance between the rotating push plate and the side plate will gradually decrease. At this time, the follower pneumatic rod far away from the rotation center of the rotating push plate will be compressed first, thereby playing a supporting effect. As the rotation continues, the remaining follower pneumatic rods will work in turn, and the follower pneumatic rods will move relatively.

[0011] In a preferred example, the present invention can be further configured as follows: a supporting pneumatic rod is also provided on the side plate, and the two ends of the supporting pneumatic rod are respectively hinged on the rotating push plate and the side plate, and the supporting pneumatic rod is located on one side of the plurality of follower pneumatic rods close to the rotation center point of the rotating push plate.

[0012] By adopting the above technical solution, the supporting gas pressure rods always remain in a working state when in the open and folded states. When the bed board is retracted into the bed frame, the supporting gas pressure rods on both sides can work together. The effect here is that the bed board can be kept in the bed frame, which can help to bring the bed board together when closing.

[0013] In a preferred example, the present invention can be further configured as follows: a follower sleeve is sleeved on the follower pneumatic rod, one end of the follower sleeve is hinged to the side panel, the length of the follower pneumatic rod gradually shortens from the rotation center point of the rotating push plate toward the outside, and when the bed board is in a vertical state, there is a gap between the end of the follower pneumatic rod and the bottom of the follower sleeve.

[0014] By adopting the above technical solution, when the bed board is opening, the follower pneumatic rod at one end away from the rotation center of the rotating push plate will move upward and slide in the follower sleeve. When the top of the follower pneumatic rod is pressed against the bottom of the follower sleeve, the follower pneumatic rod starts to work, and the bed board continues to flip down, which will compress the follower pneumatic rod that has been pressed against the follower sleeve. The number of follower pneumatic rods working will gradually increase, and finally the bed board will be supported; and when the bed board is folded, the originally compressed pneumatic rod will gradually extend, and when it is fully extended, it will slide in the follower sleeve as a whole. At this time, the follower pneumatic rod will not exert any force on the bed board.

[0015] In a preferred example, the present invention can be further configured as follows: the follower pneumatic rods on both sides are divided into a first follower group and a second follower group, and when the opening angle of the bed board gradually increases, the follower pneumatic rods of the first follower group and the follower pneumatic rods of the second follower group alternately and sequentially abut against the bottom of the follower sleeve.

[0016] By adopting the above technical solution, during the opening process, one follower pneumatic rod in the first follower group will be compressed first, and then another follower pneumatic rod in the second follower group will be compressed, and they will be alternately pressed in sequence, which can double the original number of force decomposition segments. In a smaller space, it can have a double segmented force effect, making the opening effect of the entire bed board smoother, reducing the sense of frustration when opening the bed board, and improving the comfort of use.

[0017] In a preferred example, the present invention can be further configured as follows: when the bed board is in a horizontal state, the piston rod supporting the gas pressure rod has a free stroke.

[0018] By adopting the above technical solution, when the bed board is in a horizontal state, the supporting gas pressure rod will not be in a suffocated state and can still provide support. When the bed board is likely to continue to fall, the free travel section of the supporting gas pressure rod can play a buffering role.

[0019] In a preferred example, the present invention can be further configured as follows: a rubber buffer block is provided at the end of the follower gas pressure rod located in the follower sleeve.

[0020] By adopting the above technical solution, when the top of the follower gas pressure rod hits the bottom of the follower sleeve, the rubber buffer block will play a buffering role, reducing the frustration of the follower gas pressure rod hitting the follower sleeve, and also reducing the possibility of damage.

[0021] In a preferred example, the present invention may be further configured as follows: the side plate is provided with a limiting protrusion for abutting against the rotating push plate, and the limiting protrusion is located at the end of the rotation path of the rotating push plate.

[0022] By adopting the above technical solution, when the bed board is in a horizontal state, if the telescopic balance member fails, the bed board will continue to rotate downward, and the rotating push plate will also continue to rotate and will contact the limiting protrusion, thereby forming a subsequent supporting effect and preventing the bed board from directly hitting the ground.

[0023] In a preferred example, the present invention can be further configured as follows: a limiting hole is provided on the side plate, and a gap is provided between the limiting hole and the limiting protrusion for the rotating push plate to be embedded.

[0024] When installing the bed board, it needs to be kept in a horizontal state, and at this time the gas pressure rods are in a working state, and no mattress is placed on the bed board at this time, so it is necessary to manually keep it in a horizontal state. By adopting the above technical solution, the limiting rod can be inserted into the limiting hole, so as to hold the rotating push plate against the bed board, so that the bed board is kept in a horizontal state, which is convenient for installation.

[0025] In a preferred example, the present invention can be further configured as follows: the rotating push plate is located on the side opposite to the two side plates, and there is a mounting cavity between the bed frame and the side plates.

[0026] By adopting the above technical solution, the follower pneumatic rod and the supporting pneumatic rod are placed in the installation cavity, so that the overall connection structure can be hidden to avoid the connection structure being exposed to the outside.

[0027] In summary, the present invention includes at least one of the following beneficial technical effects:

[0028] 1. When the bed board is opened, each follower gas pressure rod will gradually support the bed board as the opening angle increases. As the required support force of the bed board increases, the total support force of the follower gas pressure rod will gradually increase, and the number of follower gas pressure rods will gradually decrease when the bed board is folded, so that it can provide better support and facilitate opening and folding;

[0029] 2. When the bed board is in the process of opening, the follower pneumatic rods in the first follower group and the second follower group will work in sequence, so that the bed board can be supported in multiple sections during the whole process, and the process of opening and closing will be smoother.

[0036] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0037] The present invention discloses a flip connection structure of an invisible bed, in order to solve the problem of constant supporting force of the existing bed board 110 during the opening process. The constant supporting force will cause the bed board 110 to be difficult to open during the opening process or the supporting force required when it is close to the horizontal state is too large.

[0038] The flip connection structure of the invisible bed disclosed in this embodiment is shown in FIG. Figure 1 , including a bed frame 100, and a bed board 110 rotatably connected to the bed frame 100, telescopic balancing members are arranged between both sides of the bed board 110 and both sides of the bed frame 100, the telescopic balancing members can make the bed board 110 have a tendency to fold, and there are no less than two telescopic balancing members on each side, and the working number of the telescopic balancing members on each side is positively correlated with the opening angle of the bed board 110, so that the supporting force can be adjusted according to the angle when opening.

[0039] Reference Figure 2 , Figure 3, the side panels 120 are fixedly installed on both sides of the bed frame 100 by bolts, and the side panels 120 are rotatably connected with the rotating push plates 121 through bearings. In order to make the overall structure hidden in the bed frame 100, in this embodiment, the rotating push plates 121 are installed on the opposite sides of the two side panels 120, and there is an installation cavity 122 between the bed frame 100 and the side panels 120. The bed board 110 is coaxially connected with the rotating push plates 121 through a linkage shaft 123. One end of the linkage shaft 123 is a polygonal body, which is a regular hexagon in this embodiment. One end of the linkage shaft 123 is embedded in the inner ring of the bearing, and the end of the linkage shaft 123 away from the bearing will be fixed to the bed frame 100 by bolts, so that when the bed board 110 rotates, the rotating push plates 121 rotate accordingly.

[0040] Reference Figure 2 The telescopic balancing member is arranged between the rotating push plate 121 and the side plate 120. In this embodiment, the telescopic balancing member is a follower pneumatic rod 130. Multiple follower pneumatic rods 130 are arranged in sequence from the rotation center point of the rotating push plate 121 toward the outside, and each follower pneumatic rod 130 is sleeved with a follower sleeve 131, one end of the follower sleeve 131 is hinged on the side plate 120, and the end of the follower pneumatic rod 130 away from the follower sleeve 131 is hinged on the rotating push plate 121, and the length of the follower pneumatic rod 130 becomes shorter in sequence from the rotation center point of the rotating push plate 121 toward the outside. When the bed board 110 is in a vertical state, there is a gap between the end of the follower pneumatic rod 130 and the bottom of the follower sleeve 131.

[0041] At the same time, a supporting pneumatic rod 140 is also provided on the side panel 120. The supporting pneumatic rod 140 always remains in a working state during the opening process of the bed board 110. The two ends of the supporting pneumatic rod 140 are respectively hinged on the rotating push plate 121 and the side panel 120, and the supporting pneumatic rod 140 is located on the side of the rotation center point of the multiple follower pneumatic rods 130 close to the rotating push plate 121.

[0042] Reference Figure 2 , Figure 4When the bed board 110 is opened from the vertical state, the rotating push plate 121 rotates, and its free end will rotate toward the upper end of the side plate 120. At this time, the supporting gas pressure rod 140 will be compressed, thereby exerting a reverse force on the rotating push plate 121. However, the combined force exerted on the rotating push plate 121 will still cause the bed board 110 to continue to rotate and move toward the horizontal state. At this time, the rotating push plate continues to rotate, and the follower gas pressure rod 130 in the original length state slides in the follower sleeve 131. When the longest follower gas pressure rod 130 hits the bottom of its corresponding follower sleeve 131, this follower gas pressure rod 130 will be compressed, thereby The supporting force for the bed board 110 is increased, and the follower pneumatic rods 130 of different lengths will work step by step in sequence. As the supporting force required for the bed board 110 increases, the follower pneumatic rod 130 can provide corresponding supporting force, so that the force exerted by the human hand can be less in the whole process; and in the process of folding, the follower pneumatic rod 130 will first rebound, then maintain its original length and slide in the follower sleeve 131, and exit the working state one by one, and finally rely on the force of the supporting pneumatic rod 140 to retract the bed board 110 into the bed frame 100. When retracting, the bed board 110 moves slowly and the force is small, which is also convenient for opening later.

[0043] Reference Figure 4 In order to reduce the sense of frustration when the follower pneumatic rod 130 hits the bottom of the follower sleeve 131, a rubber buffer block 132 is installed at the end of the follower pneumatic rod 130 in this embodiment, which can absorb part of the kinetic energy of the follower pneumatic rod 130 hitting the bottom of the follower sleeve 131.

[0044] Since the bed board 110 needs to be opened as smoothly as possible, in this embodiment, the follower pneumatic rods 130 on both sides are divided into a first follower group and a second follower group. When the opening angle of the bed board 110 gradually increases, the follower pneumatic rods 130 of the first follower group and the follower pneumatic rods 130 of the second follower group are alternately pressed against the bottom of the follower sleeve 131. For example, in this embodiment, there are two follower pneumatic rods 130 on each side. In the first follower group, the follower pneumatic rods 130 and the follower pneumatic rods 130 are from the rotation center of the rotating push plate 121 to the other end. In the second follower group, the follower pneumatic rods 130 and the follower pneumatic rods 130 and the follower pneumatic rods 130 are from the rotation center of the rotating push plate 121 to the other end. The lengths from the longest to the shortest are the follower pneumatic rods 130, ... The pressure rod 130 and the No. 4 follower pneumatic rod 130 have a supporting pneumatic rod 140 on each side. When rotating, the two supporting pneumatic rods 140 work together, and then the No. 1 follower pneumatic rod 130 in the first follower group pushes to the bottom of the follower sleeve 131 for compression, and then No. 3, No. 2, and No. 4 work in turn, thereby further segmenting the open state of the bed board 110, and achieving the effect of multi-stage relay work in the limited installation cavity 122.

[0045] Reference Figure 2 In order to improve the safety after the bed board 110 is opened, when the bed board 110 is in a horizontal state, the piston rod supporting the gas rod 140 has a free stroke. When the gas rod fails, the supporting gas rod 140 can still provide support. At the same time, in order to further improve safety, the side plate 120 is provided with a limiting protrusion 124 for contacting with the rotating push plate 121. The limiting protrusion 124 is located at the end of the rotation path of the rotating push plate 121. The end referred to in this embodiment refers to the position of the rotating push plate 121 when the bed board 110 is in a horizontal state. When the gas rod fails, for example, when in use, the rotating push plate 121 will contact with the limiting protrusion 124 and temporarily play a supporting role. In normal use, when the bed feet on the bed board 110 fall on the ground, the rotating push plate 121 will not contact the limiting protrusion 124.

[0046] At the same time, in order to facilitate the installation of the bed board 110 on the bed frame 100, a limiting hole 125 is opened on the side plate 120. There is a gap between the limiting hole 125 and the limiting protrusion 124 for the rotating push plate 121 to be embedded. That is, when installing the bed board 110, it needs to be kept horizontal. At this time, each pneumatic rod is in a working state, which makes the installation troublesome. At this time, a rod-shaped object or a pin can be inserted into the limiting hole 125, which will abut against the lower side of the rotating push plate 121, thereby maintaining the state of the bed board 110 and facilitating installation.

[0047] The implementation principle of this embodiment is as follows: first, when the bed board 110 is opened from the bed frame 100, the force of the two supporting gas pressure rods 140 needs to be overcome, and one end of the rotating push plate 121 will move upward, but the combined force of the rotating push plate 121 will still cause the bed board 110 to continue to rotate and move toward a horizontal state. At this time, the rotating push plate continues to rotate, and each follower gas pressure rod 130 in the original length state slides in the follower sleeve 131. When the longest follower gas pressure rod 130 hits the bottom of its corresponding follower sleeve 131, this follower gas pressure rod 130 will be compressed, thereby increasing the support of the bed board 110. 0 supporting force, and the follower pneumatic rods 130 of different lengths will work step by step in sequence. As the supporting force required by the bed board 110 increases, the follower pneumatic rod 130 can provide corresponding supporting force, so that the force exerted by the human hand can be less in the whole process; and in the process of folding, the follower pneumatic rod 130 will first rebound, then maintain its original length and slide in the follower sleeve 131, and exit the working state one by one, and finally rely on the force of the supporting pneumatic rod 140 to retract the bed board 110 into the bed frame 100. When retracting, the bed board 110 moves slowly and the force is small, which is also convenient for opening later.

[0048] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
