Description

Technical Field

[0001] The utility model relates to the technical field of intelligent nursing mattresses, specifically to a mechanism for changing magnetic field effects by horizontal rhythmic movement and horizontal movement of a nursing mattress. Background Art

[0002] In reality, both China and the international community are rapidly approaching an aging society. The functions of nursing mattresses for the elderly are quite lacking. The bodies of the elderly have various degrees of chronic diseases, such as poor sleep quality, constipation, osteoporosis, muscle soreness and sclerosis, etc.

[0003] Rhythm technology is a physical therapy; after people lie down, through the physical action of reciprocating horizontal movement, it can change the musculoskeletal nervous system of the body, affect the endocrine and other physiological systems, and produce various beneficial health effects. This exercise method is not only suitable for young people, but also especially suitable for the elderly, because it can significantly enhance muscle activity ability, improve constipation, promote sleep, prevent osteoporosis, reduce fat, etc., and also has a positive relieving effect on cardiovascular diseases, prostate, etc.

[0004] The use of rhythmic movement has no restrictions on age, time, and location. For sedentary elderly people, especially those who are bedridden for a long time, it is particularly suitable. They can effectively "move" on their own beds and easily enjoy the fun of rhythm while standing, sitting, or even lying down, achieving many benefits that traditional exercises cannot achieve.

[0005] Existing rhythmic movements are all one-way reciprocating back-and-forth movements or up-and-down vertical movements, and the movement frequency is relatively high, with high costs, and is not very suitable for the use of the elderly and sub-healthy people; the utility model innovatively proposes a rhythmic movement that can move horizontally in both the X direction and the Y direction at a certain frequency.

[0006] Existing physiotherapy devices and physiotherapy beds on the market basically form a fixed magnetic field effect or a rotating magnetic field effect, which has certain limitations for the physical therapy of the human body; the utility model innovatively proposes a new method for changing the magnetic field effect by horizontal movement.

The fixed bracket assembly 3 and the mattress sponge pad 2 are respectively disposed inside the mattress outer cover 1. The motor eccentric wheel assembly 8 is disposed inside the fixed bracket assembly 3 and the slide rail assembly 4 that reciprocally slides in the X and Y directions. The battery assembly 10, the horizontal sensor 11, and the control box 12 are respectively disposed inside the fixed bracket assembly 3. The slide rail assembly 4 that reciprocally slides in the X and Y directions is disposed directly above the fixed bracket assembly 3 and is fixedly connected with screws 15. The slide rail assembly 4 that reciprocally slides in the X and Y directions is disposed directly above the fixed bracket assembly 3 and is fixedly connected with screws 15. The magnetic object 6 is disposed directly above the upper bracket assembly 5 or inside the upper bracket assembly 5. The magnetic objects 6 are arranged in a sequential manner to generate a corresponding magnetic field. When the upper bracket assembly 5 moves horizontally in the X direction, it will effectively cut the existing magnetic field in the X direction by dislocation. When the upper bracket assembly 5 moves horizontally in the Y direction, it will effectively cut the existing magnetic field in the Y direction by dislocation. One side of the mattress outer cover 1 is provided with a corresponding interface for charging that is docked with the battery assembly (10) and a corresponding interface for docking with the hand controller 13. The hand controller 13 is disposed outside the mattress outer cover 1 and is connected to the corresponding interface on the mattress outer cover 1. The battery assembly 10 and the control box 12 are installed at the middle position of the fixed bracket assembly 3. The horizontal sensor 11 is composed of one or more groups and is respectively installed at both ends of the fixed bracket assembly 3.

[0031] Furthermore, the fixed bracket assembly 3 can be composed of one first fixed mounting bracket assembly 3-1 or multiple second fixed mounting bracket assemblies 3-2. When the fixed bracket assembly 3 is composed of multiple second fixed mounting bracket assemblies 3-2, they can be connected by the rotational connection assembly 7.

[0032] Further, the upper bracket assembly 5 can be composed of one upper first mounting upper bracket assembly 5-1 or multiple upper second mounting upper bracket assemblies 5-2. When the upper bracket assembly 5 is composed of multiple parts, it can be connected by a rotating connection assembly 7. There are multiple first slots 5-5 for mounting the magnetic object 6 on the upper bracket assembly 5, and the first slots 5-5 are combined and arranged in a certain order. The magnetic object 6 is fixed in the corresponding first slot 5-5 with screws 15 or glue respectively, or the magnetic object 6 is fixed above the upper bracket assembly 5.

[0033] Further, the slide rail assembly 4 that reciprocally slides in the X and Y directions is composed of a set of first slide rail assemblies 4-1 or multiple sets of second slide rail assemblies 4-2, and is installed between the fixed bracket assembly 3 and the upper bracket assembly 5. A single set of the slide rail assembly 4 that reciprocally slides in the X and Y directions is composed of an upper slide rail member 41, a middle slide rail member A 42, a middle slide rail member B 43, a lower slide rail member 44, a ball 45, and a ball positioning member 46. When multiple components of the slide rail assembly 4 that reciprocally slides in the X and Y directions are combined, they are arranged in order. Dovetail grooves 4A are respectively provided on the upper slide rail member 41 and the lower slide rail member 44. The upper slide rail member 41 and the lower slide rail member 44 can be of the same or different shapes. A sliding positioning groove 4B is provided in the middle. The ball 45 is placed in the corresponding hole of the ball positioning member 46. The ball positioning member 46 is installed at the bottom in the dovetail groove 4A and fixed with screws 15. Convex male grooves corresponding to the dovetail groove 4A and provided with the sliding positioning groove 4B are respectively provided on the middle slide rail member A 42 and the middle slide rail member B 43, and the middle slide rail member A 42 and the middle slide rail member B 43 can be of the same or different shapes.

[0034] Further, the middle slide rail member A 42 and the middle slide rail member B 43 are installed and fixed in a cross shape, so that the dovetail convex male groove B direction surfaces on the middle slide rail member A 42 and the middle slide rail member B 43 are in a cross shape direction. Then, the installed lower slide rail member 44, ball positioning member 46, and ball 45 are slid and installed in place along the dovetail groove 4A, and then installed and positioned with a screw 15, so that the lower slide rail member 44 slides smoothly and with low noise under the middle slide rail member B 43, and can only slide horizontally in the direction of the dovetail groove 4A within the range of the positioning groove. Similarly, the upper slide rail member 41 can be installed; after installation, the sliding directions of the lower slide rail member 44 and the upper slide rail member 41 are in the X and Y directions.

[0035] Further, the motor eccentric wheel assembly 8 is composed of a single first eccentric wheel assembly 8-1 or multiple second eccentric wheel assemblies 8-2; the single first eccentric wheel assembly 8-1 is composed of a motor 81, an eccentric wheel 82, an eccentric wheel driving member 83 and a motor mounting bracket 84. The motor mounting bracket 84 is used to install and fix the motor 81, and the eccentric wheel 82 is installed on the motor shaft 8A and locked and fixed with a screw 15.

[0036] Further, the eccentric wheel driving member 83 is designed with a second slot 8B that cooperates with the movement of the eccentric wheel. The motor 81 drives the eccentric wheel 82 to rotate in the second slot 8B, so as to drive the eccentric wheel driving member 83 to move horizontally. The moving range is the eccentric dimension of the eccentric wheel 82. The eccentric wheel driving member 83 is fixedly connected to the upper bracket assembly 5. The motor mounting bracket 84 is fixed to the middle part of the fixed bracket assembly 3 with a screw 15. When driving the upper bracket assembly 5 to move horizontally in the X direction, a single or several motor eccentric wheel assemblies 8 are used. When driving the upper bracket assembly 5 to move horizontally in the Y direction, a single or several motor eccentric wheel assemblies 8 are used. When the motor 81 is charging, it drives the eccentric wheel 82 to rotate, so that the eccentric wheel driving member 83 makes a horizontal movement, and then drives the upper bracket assembly 5 to make a horizontal movement. The user lies on it for horizontal rhythmic movement.

[0037] Working principle: The motor eccentric wheel assembly 8 is responsible for driving the upper bracket assembly 5 to move horizontally in the X and Y directions, so as to generate a specific magnetic field effect and rhythmic movement. The motor eccentric wheel assembly 8 is composed of a motor 81, an eccentric wheel 82, an eccentric wheel driving member 83 and a motor mounting bracket 84. The motor mounting bracket 84 is fixed to the middle part of the fixed bracket assembly 3 with a screw 15 to ensure stable support. The eccentric wheel driving member 83 is designed with a second slot 8B that cooperates with the movement of the eccentric wheel 82. When the motor 81 is started, it drives the eccentric wheel 82 to rotate in the second slot 8B. Due to the eccentric design of the eccentric wheel 82, this rotation is converted into the horizontal movement of the eccentric wheel driving member 83, and the moving range is equal to the eccentric dimension of the eccentric wheel 82. The eccentric wheel driving member 83 is fixedly connected to the upper bracket assembly 5. Therefore, when the eccentric wheel driving member 83 moves, the upper bracket assembly 5 will also move accordingly. Magnetic objects 6 are installed on the upper bracket assembly 5, and these magnetic objects are arranged in a sequential manner, so as to generate a corresponding magnetic field. When the upper bracket assembly 5 moves in the X or Y direction, it will effectively cut the existing magnetic field in a staggered manner. In order to drive the upper bracket assembly 5 to move horizontally in the X direction, a single or multiple motor eccentric wheel assemblies 8 can be used. Similarly, in order to drive the upper bracket assembly 5 to move horizontally in the Y direction, a single or multiple motor eccentric wheel assemblies 8 can also be used. These motor eccentric wheel assemblies 8 can work independently or simultaneously according to needs to achieve the complex rhythmic movement of the mattress.

[0038] When the motor 81 is charged and started, it drives the eccentric wheel 82 to rotate. This rotation is then converted into the horizontal movement of the eccentric wheel driving member 83, which in turn drives the upper bracket assembly 5 to move horizontally. When the user lies on the mattress, they can feel this horizontal rhythmic movement, which helps to improve sleep quality, promote blood circulation, or provide other health benefits.
