According to the scheme, the torsion is gradually and mainly matched with a pair of supports, when the torsion assembly breaks down, parts can be conveniently replaced, the massage assembly does not need to be internally disassembled, and the maintenance convenience of the machine core is improved.

Description

Technical Field

[0001] The utility model relates to the field of massage devices, in particular to a foldable massage mechanism. Background Art

[0002] With the increasing attention of people to the quality of daily life, in daily work, people often suffer from neck, shoulder and back pain due to maintaining a certain posture without moving. As a popular massage device at present, the massage device for neck, shoulder and back (such as a massage chair) is sought after by many consumers because of its advantages of convenient operation and reliable massage. However, most of the current commercially available massage devices achieve massage by directly rotating and pressing or pressing back and forth deeply and shallowly. At the same time, during the massage process, the object to be massaged needs to keep in contact with the massage component of the massage device through the back to achieve continuous massage. This requires the user to learn and adapt their posture to some extent when using. Although there are some commercially available products on the market that improve the contact reliability between the massage component and the user's back, neck and shoulders by setting elastic components, most of them involve complex cooperation structures. For adult users, due to the relatively large body weight of adults, when the elastic component maintains the contact between the massage component and the user, after long-term use under pressure, certain abnormal conditions such as part deformation and damage may occur, affecting the use reliability of the massage mechanism. And the complex cooperation structure will lead to high maintenance costs. Therefore, how to simplify the structural form of the massage mechanism and at the same time make it capable of adapting to the user's posture and providing reliable contact maintenance between the massage component and the user is a research topic with very positive practical significance. Summary of the Utility Model

[0004] In order to achieve the above technical purpose, the technical solution adopted by the present utility model is as follows:

[0005] A foldable massage mechanism, comprising:

[0006] Brackets, a pair of which are both U-shaped frame structures, and the U-shaped open ends of the pair of brackets face each other;

[0007] Torque components, a pair of which are respectively connected between the two sides of the U-shaped open ends of the pair of brackets to rotationally and constraint-connect the pair of brackets;

[0009] Wherein, there are a first state and a second state that cooperate with each other between the pair of brackets,

[0010] In the first state, an included angle α is formed between a pair of the brackets, and the torsion assembly is in an initial state;

[0011] In the second state, at least one of a pair of the brackets rotates and unfolds around the torsion assembly under the action of a force, so that the torsion assembly is deformed by the drive of the brackets, and it changes from the initial state to a deformed state.

[0012] As a possible implementation manner, further, limiting pieces for cooperating with the torsion assembly are arranged on both sides of the open end of the bracket in this solution. First connection through holes are arranged on both sides of the open end of one bracket, and extension pieces extending to both sides of the open end of one bracket are arranged on both sides of the open end of the other bracket. Second connection through holes are arranged on the extension pieces corresponding to the first connection through holes; a pair of the torsion assemblies are respectively connected in cooperation with the first connection through holes, the second connection through holes and the limiting pieces on both sides of the open ends of a pair of the brackets;

[0013] The torsion assembly includes a bolt, a nut and a torsion spring.

The nut is threadedly connected to the screw part of the bolt and confines the torsion spring on the screw part of the bolt.

[0014] As a better implementation option, preferably, the torsion assembly in this solution further includes a gasket. The gasket is sleeved on the screw part of the bolt and is located between the torsion spring and the nut.

[0015] As a possible implementation manner, further, limiting blocks are arranged on both sides of the open end of one bracket in this solution. The limiting blocks are used for limiting the amplitude of the mutual approach of a pair of the brackets under the action of the torsion assembly.

[0016] As a possible implementation manner, further, the included angle α in this solution is greater than 120 degrees and less than 180 degrees.

[0017] As a better implementation option, preferably, the massage assembly in this solution includes:

[0018] A first outer shell, fixed on one of the brackets, and provided with a pair of opposite mounting parts thereon;

[0019] Worm gears, the number of which corresponds to the pair of the mounting parts one by one, and are respectively rotatably connected to the mounting parts through rotating shafts;

[0020] A drive motor is fixed on the first housing. The drive motor is a dual-axis motor, and worms are provided on both of its two drive shafts.

When the massage mechanism does not receive an external force, the torsion assembly can make the pair of brackets maintain a certain included angle. When the user leans their back against the pair of massage assemblies of the mechanism, the pair of brackets will drive the torsion assembly to deform due to the force transmitted by the massage assemblies, so that the pair of massage assemblies rotate following the pair of brackets, and keep in contact with the user's back, avoiding causing back discomfort to the user because the massage assemblies cannot adapt to the user's back leaning posture; it improves the application humanization and reliability of the massage mechanism. In addition, the torsion of this solution is mainly coordinated with the pair of brackets. Therefore, when the torsion assembly fails, it is convenient to replace the components without having to disassemble the inside of the massage assembly, improving the maintenance convenience of the mechanism.

[0035] Massage components 300, which are a pair and are respectively connected to the pair of brackets 100a and 100b;

[0036] Among them, there are a first state and a second state that cooperate with each other between the pair of brackets 100a and 100b,

[0037] In the first state, an included angle α is formed between the pair of brackets 100a and 100b, and the torsion component 200 is in an initial state;

[0038] In the second state, at least one of the pair of brackets 100a and 100b is subjected to a force and rotates and unfolds around the torsion assembly 200, causing the torsion assembly 200 to deform under the drive of the bracket 100, changing it from the initial state to the deformed state.

[0039] Wherein, on both sides of the open end of the bracket 100 in this solution, there are limit pieces 101 for cooperating with the torsion assembly 200.
