Description

Technical Field

[0001] The invention relates to the technical field of mattress stabilization, and in particular to an anti-dislocation mattress which is convenient for multi-directional adjustment. Background Art

[0002] Traditional mattress designs are often relatively fixed, which cannot meet people's diverse needs for comfortable sitting postures when performing non-sleeping activities in bed (such as reading, watching TV, etc.). In order to create a more comfortable and healthy sleeping and resting environment, multi-directional adjustable mattresses came into being. This type of mattress allows users to flexibly adjust the angle and shape of the mattress according to their preferences, so that they can easily find the sleeping posture that suits them best. Whether they prefer the solid support of a hard mattress or the gentle wrapping of a soft mattress, they can all be satisfied through simple adjustments.

[0003] However, there is a common problem in the use of products on the market: the mattress and the bed are prone to sliding and misalignment. In order to solve this problem, existing designs usually use anti-slip mats, mattress fixing belts or mattress pads to try to maintain the stability of the mattress by increasing the friction between the mattress and the bed. Although these methods can reduce the misalignment of the mattress to a certain extent, they cannot fundamentally solve the problem. Once the mattress is misaligned, the user often still needs to adjust it manually, which undoubtedly reduces the use experience. In addition, when the mattress itself is subjected to external forces, the internal structure is prone to displacement and deformation, which will not only seriously affect the support and comfort of the mattress, but also may shorten its service life. Secondly, in some bed frames, due to unreasonable bed frame design or small mattress thickness, the height of the mattress does not match the depth of the bed. When the bed frame is too high, such a bed frame appears too bulky and not beautiful from a visual point of view. From the user experience, it will be inconvenient to get in and out of bed, and may even cause the user to be injured after touching the harder bed frame while sleeping; when the bed frame is too low, or even the thickness of the mattress exceeds the depth of the bed frame, the mattress will easily slide or shift during use, which will not only affect the sleep comfort, but also cause damage to the mattress, and even lead to the risk of people falling due to mattress shifting during sleep.

[0032] The lifting mechanism 3 is also provided with a piezoelectric ceramic power generation module 316, which is evenly distributed on the upper surface of the lead plate 31, and the lower end of the mattress 2 is closely attached to the piezoelectric ceramic power generation module 316. The piezoelectric ceramic power generation module 316 is connected to a battery. When a person lies on the mattress 2, the piezoelectric ceramic power generation module 316 is pressurized to generate electricity and is stored in the battery. The battery is electrically connected to the air pump, the drive motor 315 and the reset mechanism 4, thereby improving the power support for the entire anti-misalignment mattress. The user's gender is judged by the pressure distribution pattern (the pressure concentration of male shoulders is 18-22% higher than that of females), so as to dynamically adjust the hardness of the lumbar support area (the default hardness for males is +15%, and the default curvature radius for females is +10%) to meet different customer needs.

[0033] The reset mechanism 4 includes a fixed shell 41, a connecting shaft 42, a cable guide wheel 43, a retaining spring block 44, a torsion spring 45, a torque sensor 46 and a reset rope 47. The fixed shell 41 is installed on the lower end surface of the lead plate 31, the connecting shaft 42 is rotatably set in the fixed shell 41, the cable guide wheel 43 is sleeved on the connecting shaft 42, the torque sensor 46 is installed on the end of the connecting shaft 42, the torsion spring 45 is sleeved on the connecting shaft 42, the retaining spring block 44 is fixedly mounted on the end of the cable guide wheel 43, and the retaining spring block 44 abuts against the torsion spring 45, one end of the reset rope 47 is fixedly mounted on the lead plate 31, wound around the cable guide wheel 43, and after passing through the fixed shell 41 and the bed 1 in sequence, the other end of the reset rope 47 is fixedly mounted on the bed 1.

[0034] A movable groove is provided at the bottom of the inner cavity of the fixed shell 41, a snap-in groove is provided on the outer surface of the fixed shell 41, a built-in motor is arranged inside the connecting shaft 42, the built-in motor is electrically connected to the external controller, the end of the torque sensor 46 away from the torsion spring 45 is fixedly connected to the inner wall of the fixed shell 41, the torque sensor 46 is electrically connected to the external controller, the reset rope 47 is wrapped around the outer surface of the guide wheel 43 and passes through the movable groove, and a snap-in block is provided at the end of the reset rope 47 away from the top of the inner cavity of the fixed shell 41, and the snap-in block is snap-connected to the snap-in groove.

[0035] The material of the reset rope 47 is set to be rubber, which is convenient for the reset rope 47 to be wound around the surface of the bed body 1, thereby assisting in fixing the mattress 2 to the bed body 1, preventing the mattress 2 from being misplaced, and automatically correcting it when it is not in use and is misplaced.

[0036] Working principle:

[0037] In the initial state: the connecting rod 36 is inside the second raised groove block 311 and away from the second fixed block 310, the sliding block 34 is inside the first raised groove block 33 and away from the first fixed block 37, the torsion spring 45 is not tightened, and the end of the reset rope 47 away from the interior of the fixed shell 41 is located on the outer surface of the fixed shell 41, and the reset rope 47 is wrapped around the outer surface of the guide wheel 43.

[0038] When working:

[0039] Initial preparation: the user places the mattress 2 on the upper surface of the bed body 1. At this time, the second fixing plate 312 at the bottom of the mattress 2 will contact the inner surface of the bed body 1. At this time, the mattress 2 is placed above the bed body 1. The user can adjust the movement of the lifting mechanism 3 through the external controller to adapt the mattress 2 to the bed body 1. The head and foot of the bed body 1 in the invention are higher than the mattress 2. During the rising process, the mattress 2 will only be level with the frames on both sides of the bed body 1, thereby ensuring that the user can use it conveniently when getting on and off from both sides. During the use of the mattress 2, due to the higher limiting effect of the head and foot of the bed, the mattress 2 will move left and right, that is, the mattress 2 moves left and right on the upper surface of the bed body 1, and the second fixing plate 312 moves left and right on the inner surface of the bed body 1. In order to prevent the displacement of the mattress 2 from affecting the user's experience, the reset rope 47 inside the reset mechanism 4 will pass through the holes opened in the baffles on both sides of the bed body 1 or under the baffles on both sides of the bed body 1, and finally return to the clamping groove on the outer surface of the reset rope 47 to achieve the limited installation of the mattress 2 on the bed body 1. When the clamping block on the reset rope 47 is not clamped with the clamping groove, the torsion spring 45 inside the fixed housing 41 is in a non-powered state. When the user pulls the clamping block on the reset rope 47, the reset rope 47 is wound around the surface of the cable guide wheel 43. When the user pulls the clamping block, the reset rope 47 drives the cable guide wheel 43 to rotate, thereby reducing the reset rope 47 wound around the surface of the cable guide wheel 43. Since the cable guide wheel 43 is fixedly connected to the clamping spring block 44, the rotation of the cable guide wheel 43 drives the clamping spring block 44 to rotate. The rotation drives the torsion spring 45 to rotate, and then the rotation of the torsion spring 45 drives the torsion spring 45 itself to generate a tightening force, and at this time the tightening force of the torsion spring 45 itself is constant. At the same time, as the user pulls, the reset rope 47 passes through the hole opened in the baffle on one side of the bed body 1 or passes under the baffle on one side of the bed body 1, and then the clamping block is clamped with the clamping groove. When the clamping state is released, the reset rope 47 is affected by the torsion force of the torsion spring 45, and then returns to the initial state. At this time, the mattress 2 is no longer installed with the bed body 1 in a limited position.

[0040] The depth of the mattress 2 and the inner frame of the bed 1 is matched:

[0041] In some bed frame 1, due to unreasonable design of bed frame 1 or small thickness of mattress 2, the depth between bed frame 1 and mattress 2 does not match. When the depth difference is too large, that is, the four sides of bed frame 1 are too high, it will make getting in and out of bed inconvenient, and even cause the user to be injured after touching the harder bed frame 1 while sleeping. At this time, the user electrically controls the external drive device to start through the external controller, and the external drive device starts to drive the threaded rod 314 to rotate. Because the thread groove inside the fixing nut 313 is adapted to the thread on the outer surface of the threaded rod 314, when When the threaded rod 314 rotates, the fixing nut 313 moves in the direction of the thread rotation. The movement of the fixing nut 313 drives the connecting rod 36 to slide inside the second protruding groove block 311 toward the end close to the second fixing block 310. The sliding of the connecting rod 36 drives the first rotating rod 35 to slide toward the side close to the second fixing block 310. At the same time, the sliding block 34 at the top of the first rotating rod 35 slides inside the first protruding groove block 33 toward the side close to the first fixing block 37. Since the first rotating rod 35 is cross-rotated and connected with the second rotating rod 38, the first rotating rod 35 is rotated in a direction opposite to the first rotating rod 38. During the sliding process of the bottom end, the clamping rod 39 is rotated with the axis and cross-convexed with the second rotating rod 38. The first rotating rod 35 and the second rotating rod 38 cross-convexly converge to make the first fixing plate 32 lift upward, and the first fixing plate 32 lifts upward to drive the lead plate 31 fixedly connected thereto to lift upward, and the lead plate 31 lifts upward to drive the mattress 2 to lift upward, thereby achieving the adaptation of the mattress 2 to the internal frame of the bed body 1, and the threaded rod 314 rotates to drive the connecting rod 36 to slide in the second convex groove block 311, while driving the lead plate 31 to move up and down, thereby achieving the adaptation of the mattress 2 to the internal frame of the bed body 1. By adapting the depth between the mattress 2 and the internal frame of the bed body 1 and maintaining the depth matching between the bed body 1 and the mattress 2, the overall aesthetics of the bed body 1 is improved, the convenience of getting in and out of bed is ensured, and the risk of users being injured by touching the frame of the bed body 1 is avoided, thereby significantly enhancing the user experience and safety. At the same time, since the mattress 2 can be adjusted up and down, there is a smaller gap between the mattress 2 and the bed body 1. These gaps can play a better role, increase air flow, keep the mattress 2 dry and clean, and prevent moisture and mold.

[0042] Straighten the misaligned mattress 2:

[0043] When the mattress 2 is used by the user or is subjected to external force, it will be displaced from the bed body 1. In this process, due to the displacement of the mattress 2, the reset rope 47 is stretched again. After being stretched, the reset rope 47 drives the cable guide wheel 43 wound therewith to rotate, and the rotation of the cable guide wheel 43 drives the connecting shaft 42 to rotate. At the same time, the rotation of the cable guide wheel 43 drives the retaining spring block 44 to rotate, and the rotation of the retaining spring block 44 drives the torsion spring 45 to rotate, and the rotation drives the torsion spring 45 itself to generate a tightening force. In the above-mentioned preparation work, the torsion spring 45 has already generated a tightening force, and at this time the tightening force of the torsion spring 45 itself is constant. The torque sensor 46 sets the constant value at this time as a preset value. When the mattress 2 is displaced, the tightening force of the torsion spring 45 will undergo a new change, that is, gradually increase or instantaneously increase. As the tightening force of the torsion spring 45 increases, the torque sensor 46 will be sensed by the increase in the tightening force, and judge whether the tightening force of the torsion spring 45 changes in a large range outside the preset value. When it changes in a large range outside the preset value, the mattress 2 is displaced. At this time, the torque sensor 46 will send an electrical signal to the external controller. After receiving the electrical signal, the external controller drives the built-in motor to rotate. The rotation of the built-in motor drives the connecting shaft 42 to rotate. The connecting shaft 42 The rotation drives the cable guide wheel 43 to rotate, the rotation of the cable guide wheel 43 drives the clamping spring block 44 to rotate, the rotation of the clamping spring block 44 drives the torsion spring 45 to rotate, the rotation of the torsion spring 45 reduces its own torsional force and restores it to the initial state when the clamping block and the clamping groove are clamped, and at the same time, as the cable guide wheel 43 rotates, the reset rope 47 is wound around the outer surface of the cable guide wheel 43, at this time the reset rope 47 will be contracted, and the contraction of the reset rope 47 drives the mattress 2 to change its position relative to the bed body 1, thereby realizing the correction of the misaligned mattress 2, and the setting of the torque sensor 46 senses whether the torsion spring 45 generates torque, thereby judging whether the mattress 2 is relative to the bed body 1. When displacement occurs, the real-time detection function is realized. At the same time, after detecting that the torsion spring 45 generates torque, the torque sensor 46 sends an electrical signal to the external controller to control the built-in motor to drive the connecting shaft 42 to rotate, and then the reset rope 47 is wound around the guide wheel 43 and contracted, so as to straighten the misplaced mattress 2 and fit it to the bed body 1, realizing the automatic adjustment function. The user does not need to spend too much time and energy to manually adjust the mattress 2, and the mattress 2 can be quickly and accurately reset through the rotation control of the built-in motor, which is more accurate and faster than manual adjustment, ensuring that the mattress 2 is restored to the correct position and restores its original support and comfort.
