Description

Technical Field

[0001] This utility model relates to the field of massage mechanism technology, and in particular to a massager and massage mechanism with adjustable massage intensity. Background Technology

[0002] As people's living standards improve, their pursuit of health and comfort is also increasing. Massage equipment, as a health care device that can relieve physical fatigue and promote blood circulation, has been widely favored by consumers. The massage mechanism, as the core component of massage equipment, directly affects the massage effect and user experience.

[0003] Currently, there are many types of massage mechanisms on the market, and their functions are becoming increasingly diverse. Common massage mechanisms mainly use drive components to move massage components in various ways to massage different parts of the body. Among them, the lifting and lowering movement of the massage components is a relatively common massage method. By moving the massage heads up and down, it simulates the pressing action of a human hand, thereby achieving the purpose of relaxing muscles and relieving fatigue.

[0004] Existing massage mechanisms have several shortcomings in terms of massage head lifting and lowering. Structurally, most massage mechanisms use a simple connection between the drive and massage components, with the rotating part directly driving the lifting shaft, lacking an effective mechanism to limit the massage head's rotation. This makes it easy for the massage head to follow the rotating part during the lifting process, leading to uncontrolled massage direction. In practical use, when the massage head cannot massage in the preset linear direction, it cannot accurately target the target muscle groups or acupoints, failing to achieve the desired relaxation effect. For example, when massaging the neck and shoulders, if the massage head rotates, it may not effectively stimulate key acupoints in the neck and shoulders, failing to adequately relieve neck and shoulder pain and stiffness. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a massager and massage mechanism with adjustable massage intensity.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A massage mechanism with adjustable massage intensity includes a housing, a drive assembly, and a massage assembly. The massage assembly includes a lifting shaft and a massage head fixed to the lifting shaft. The drive assembly includes a rotating component that drives the lifting shaft to move vertically between a first position and a second position, the first position and the second position being spaced apart axially from the lifting shaft. The massage assembly further includes: A damping mechanism is configured to apply a damping force to the massage head during the lifting and lowering of the lifting shaft, thereby limiting the massage head and the lifting shaft from rotating with the rotating component; The damping mechanism includes: A damping element that presses against the massage head and maintains frictional contact with the massage head during the lifting and lowering of the lifting shaft; and A positioning element is used to position and install the damping element to limit the damping element from rotating with the massage head.

[0007] Furthermore, when the massage head is driven to move up and down to the first or second position, it is configured to rotate with the rotating member to perform a massage action.

[0008] Furthermore, the rotating component has an arc-shaped groove extending both circumferentially and axially, and a shaft pin adapted to the arc-shaped groove is fixedly connected to the lifting shaft. During the rotation of the rotating component, the arc-shaped groove drives the shaft pin to move up and down.

[0009] Furthermore, the upper closed end of the arc-shaped groove defines a first position of the massage head, and its lower closed end defines a second position of the massage head.

[0010] Furthermore, a central hole is defined within the rotating component, the lifting shaft is inserted into the central hole, and a drive gear is attached to the rotating component, the drive gear being connected to a motor.

[0011] Furthermore, the rotating component and the lifting shaft are connected by a threaded transmission, so that when the rotating component is driven to rotate, the lifting shaft can move up and down through the threaded transmission.

[0012] Furthermore, the positioning element is configured to follow the up-and-down movement of the massage head, but is restricted to follow the rotation of the massage head.

[0013] Furthermore, the massage head, lifting shaft, and rotating component are all configured as a pair spaced apart in the left-right direction; the positioning component extends in the space between the pair of massage heads, and its two ends are respectively movably sleeved on the two massage heads.

[0014] Furthermore, each end of the positioning member has an annular fitting portion, which allows the rotating member to be rotatably supported on the rotating member.

[0015] Furthermore, the damping element and the positioning element are in abutting contact through a wedge structure, and the damping element abuts against the positioning element by means of an elastic element, the elastic element causing the damping element to apply force to the damping element in the direction of approaching the massage head under the action of the wedge structure.

[0016] Furthermore, the wedge structure includes an inclined surface disposed on the damping member and a pressing portion disposed on the positioning member, wherein the pressing portion and the inclined surface are in pressing contact.

[0017] Furthermore, the positioning member has a positioning post, and the damping member has a sliding groove adapted to the positioning post. The sliding groove is configured to allow the damping member to move closer to or further away from the massage head under the combined action of the elastic member and the wedge structure. The elastic member is sleeved on the positioning post and presses against the damping member.

[0018] A massager with adjustable massage intensity, the massager having the above-described massage mechanism.

[0019] Due to the adoption of the above technical solutions, this utility model has the following beneficial effects: 1. The massage mechanism of this utility model effectively solves the problem of the massage head following the rotation of the rotating parts in the prior art by setting a damping mechanism. During the lifting and lowering process of the lifting shaft, the damping element of the damping mechanism presses against the massage head and maintains frictional contact, while the positioning element restricts the damping element from rotating with the massage head, thereby applying a stable damping force to the massage head and ensuring that the massage head moves up and down between the first and second positions along a predetermined linear trajectory. This precise lifting and lowering movement allows the massage head to accurately act on the target muscle groups and acupoints, greatly improving the accuracy and effectiveness of the massage. For example, when massaging the shoulders, neck, waist, and other areas, it can accurately stimulate key acupoints, effectively relieve muscle fatigue and soreness, promote blood circulation, and bring users a better massage experience.

[0020] 2. When the massage head is driven to move up and down to the first or second position, it can rotate with the rotating component to perform massage actions. This feature allows the massage mechanism to not only perform linear massage with up and down movement, but also to perform rotational massage at specific positions, enriching the massage techniques and movements.

[0034] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other.

[0035] Example 1: Please see Figures 1-4This utility model discloses a massage mechanism with adjustable massage intensity, which is mainly used in massage pillows, cushions, or massage chairs. In this embodiment, the massage mechanism mainly consists of a housing 100, a drive assembly 200, and a massage assembly 300. The housing 100 serves as the support and protection structure for the entire massage mechanism, providing installation space and protection for other internal components, ensuring that each component operates in a stable environment. The drive assembly 200 is the power source and transmission core of the massage mechanism, driving the massage assembly 300 to perform specific movements, thereby achieving the massage function. The massage assembly 300 simulates massage actions through its own movement, providing users with a comfortable massage experience. In this embodiment, the drive assembly 200 includes a rotating component 210, a drive gear 230, and a motor 220. The rotating component 210 is the core component of the drive assembly, defining a central hole 211. The diameter of the central hole 211 matches the diameter of the lifting shaft 310, which is inserted into the central hole 211, allowing it to move up and down within the central hole 211. The rotating component 210 has an arc-shaped groove 410 extending both circumferentially and axially. The upper closed end 412 of the arc-shaped groove 410 defines a first position of the massage head 320, and the lower closed end 413 defines a second position of the massage head 320. In this embodiment, the first and second positions are spaced apart axially from each other on the lifting shaft 310. The arc-shaped groove 410 also includes a drive portion 411 disposed between the upper closed end 412 and the lower closed end 413. The drive portion 411 is inclined, allowing the arc-shaped groove 410 to drive the shaft pin 420 to move up and down during the rotation of the rotating component 210. A drive gear 230 is attached to the rotating component 210, and the two are fixed together by a gear connection to ensure that the drive gear 230 rotates synchronously when the rotating component 210 rotates. The drive gear 230 is connected to a motor 220, which acts as a power source, transmitting power to the rotating component 210 through the drive gear 230, thereby driving the rotating component 210 to rotate. The motor 220 can adjust its rotation speed according to different massage needs. The massage assembly 300 includes a lifting shaft 310, a massage head 320, and a damping mechanism 330. A pin 420 adapted to the arc-shaped slide groove 410 is fixed to the lifting shaft 310. The diameter of the pin 420 is slightly smaller than the width of the arc-shaped slide groove 410, allowing the pin 420 to slide smoothly within the arc-shaped slide groove 410. During the rotation of the rotating component 210, the arc-shaped slide groove 410 drives the pin 420 to move up and down, thereby causing the lifting shaft 310 to move up and down between a first position and a second position. The massage head 320 is fixed to the top of the lifting shaft 310. When the massage head 320 is driven to move up and down to the first position or the second position, it is configured to rotate with the rotating member 210 to perform a massage action.As the massage head 320 rotates along with the rotating part 210, it can perform kneading, rubbing, and other massage actions on the muscles of the human body, thereby relaxing the muscles and relieving fatigue.

[0036] Please see Figures 5-7The damping mechanism 330 is an important part of this massage mechanism. It is configured to apply a damping force to the massage head 320 during the lifting and lowering of the lifting shaft 310, thereby limiting the rotation of the massage head 320 and the lifting shaft 310 following the rotation of the rotating component 210. The damping mechanism 330 includes a damping element 331 and a positioning element 332. The damping element 331 is made of POM material, which has excellent properties such as high strength, high rigidity, wear resistance, self-lubrication, and fatigue resistance. The damping element 331 presses against the massage head 320 and maintains frictional contact with the massage head 320 during the lifting and lowering of the lifting shaft 310. The positioning element 332 is used to position and install the damping element 331 to limit the rotation of the damping element 331 following the massage head 320. In this embodiment, the positioning element 332 is configured to be allowed to move up and down with the massage head 320, but is restricted from rotating with the massage head 320. Specifically, the positioning member 332 extends within the space between a pair of massage heads 320, and its two ends are movably fitted onto the two massage heads 320 to move synchronously with them. Each end of the positioning member 332 has an annular fitting portion 3321 fitted outside the massage heads 320, allowing the rotating member 210 to be rotatably supported on it. A limiting portion 3322 is disposed between the two annular fitting portions 3321, configured to restrict rotation of the mounting portion when the annular fitting portions 3321 move synchronously with the lifting shaft 310. When the motor 220 starts, it drives the rotating member 210 to rotate via the drive gear 230. The arc-shaped groove 410 on the rotating member 210 drives the shaft pin 420 to move up and down, thereby causing the lifting shaft 310 and the massage heads 320 to move up and down between a first position and a second position. During the lifting and lowering process, the damping element 331 of the damping mechanism 330 maintains frictional contact with the massage head 320, applying a damping force to the massage head 320 and restricting the massage head 320 and the lifting shaft 310 from rotating with the rotating member 210. When the massage head 320 is lifted to the first position or the second position, the massage head 320 can rotate with the rotating member 210 to perform a massage action. The damping element 331 and the positioning member 332 are in abutting contact through a wedge structure, and the damping element 331 abuts against the positioning member 332 by means of an elastic member 500. The elastic member 500 causes the damping element 331 to exert force on the damping element 331 in the direction of approaching the massage head 320 under the action of the wedge structure. The elastic member 500 is installed between a screw 600 and the damping element 331, and the bottom surface of the damping element 331 and the top surface of the screw 600 respectively provide abutting force to the elastic member 500. The wedge structure includes an inclined surface 3311 disposed on the damping member 331 and a pressing part 3323 disposed on the positioning member 332, with the pressing part 3323 and the inclined surface 3311 in abutting contact. This wedge structure design enables the damping member 331 to apply damping force to the massage head 320 more stably under the combined action of the elastic member 500 and the wedge structure.During the operation of the massage mechanism, the elastic element 500 always applies an upward elastic force to the damping element 331, so that the inclined surface 3311 of the damping element 331 and the pressing part 3323 of the positioning element 332 are in close contact.

[0037] Example 2: The difference between this embodiment and Embodiment 1 is that, in this embodiment, the lifting shaft 310 has an external thread that matches the internal thread of the rotating component 210. The rotating component 210 and the lifting shaft 310 are connected by a threaded transmission. When the rotating component 210 is driven to rotate, the lifting shaft 310 can move up and down via the threaded transmission. After the motor 220 starts, it drives the rotating component 210 to rotate. Because the rotating component 210 and the lifting shaft 310 are connected by a threaded transmission, the rotation of the rotating component 210 causes the lifting shaft 310 to move up and down, thereby driving the massage head 320 to rise and fall. During the rising and falling process, the damping element 331 of the damping mechanism 330 applies a damping force to the massage head 320, restricting its rotation following the rotating component 210. When the massage head 320 reaches a suitable position, it can rotate with the rotating component 210 to perform a massage action. By controlling the speed and direction of rotation of the motor 220, the rising and falling speed and rotation mode of the massage head 320 can be adjusted to meet different massage needs.

[0038] In other embodiments, there may be one or more massage components. When there are multiple massage components, the positioning member 332 has a positioning post configured to restrict the rotation of the mounting portion when the annular fitting portion 3321 moves synchronously with the lifting shaft 310. The damping member 331 has a sliding groove adapted to the positioning post, configured to allow the damping member 331 to move closer to or further away from the massage head 320 under the combined action of the elastic member 500 and the wedge structure. The elastic member 500 is sleeved on the positioning post and presses against the damping member 331. This structure makes the damping member 331 more stable during movement and can better adapt to the working needs of multiple massage components. When the massage head 320 moves up and down, the damping member 331 slides along the positioning post in the sliding groove, while the elastic member 500 always applies elastic force to the damping member 331, ensuring stable friction between the damping member 331 and the massage head 320, thereby effectively restricting the rotation of the massage head 320.

[0039] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
