Description

Technical Field

[0001] This utility model relates to the technical field of massagers, and in particular to a flexible massage mechanism. Background Technology

[0002] With the development of technology in the massager industry, a variety of massage devices for relieving human fatigue have emerged on the market, such as massage shawls and massage lumbar cushions for massaging the shoulders, neck, waist and back.

[0003] Massage mechanisms installed in some massage chairs or regular seats often need to move up and down. In order to better match the curvature of the backrest of the massage chair or regular seat, a flexible toothed rack that can be elastically deformed along the curvature of the backrest is used to cooperate with the mechanism so that the massage heads on the mechanism fit the back of the human body more closely. However, due to the curvature of the flexible toothed rack, the meshing degree between the gears on the mechanism and the flexible toothed rack is not ideal, which makes it easy to get stuck during massage. Therefore, it is necessary to develop a flexible massage mechanism that moves smoothly. Utility Model Content

[0004] The present invention aims to at least partially solve one of the technical problems in the aforementioned technologies. Therefore, one objective of the present invention is to provide a flexible massage mechanism that has a simple structure, smooth movement, and facilitates massage for the user.

[0005] To achieve the above objectives, embodiments of this utility model provide a flexible massage mechanism, which includes: a flexible rack and a mechanism assembly;

[0006] The movement assembly has a housing and a drive unit disposed within the housing. The housing defines a limiting channel that is open on one side. A gear of the drive unit extends into the limiting channel from the open portion of the limiting channel. A flexible rack is slidably disposed within the limiting channel. The inner sidewall of the limiting channel is provided with a first elastic protrusion that can elastically contact the flexible rack. The flexible rack is confined within the limiting channel and meshes with the gear so that when the gear rotates, it can drive the movement assembly to travel along the length direction of the flexible rack.

[0007] According to an embodiment of this utility model, a flexible massage mechanism comprises a flexible rack that passes through a limiting channel of a mechanism assembly and engages with a gear in the mechanism assembly. This allows the mechanism assembly to move up and down under the rotation of the gear, facilitating the movement of the massage heads on the mechanism assembly to massage the user's back. A first elastic protrusion within the limiting channel contacts the flexible rack, allowing the limiting channel to enclose the flexible rack and engage with the gear. Simultaneously, the channel provides space for the flexible rack to deform, ensuring smoother movement of the mechanism assembly in both straight lines and curves. This flexible massage mechanism has a simple structure, smooth movement, and is beneficial for the user's massage experience.

[0008] In addition, the flexible massage mechanism proposed in the above embodiments of this utility model may also have the following additional technical features:

[0009] Optionally, the flexible rack is provided with a limiting strip along its length, and the limiting channel has a limiting groove adapted to the limiting strip.

[0010] Optionally, the housing includes a movement housing and a first connector detachably connected to the movement housing, the limiting channel is disposed on the first connector, and the gear is disposed on the movement housing.

[0011] Optionally, it also includes a flexible strip disposed opposite to the flexible rack, and the housing is provided with a sliding channel disposed opposite to the limiting channel, the flexible strip being slidably inserted into the sliding channel.

[0012] Furthermore, the inner wall of the sliding channel is provided with a second elastic protrusion that can elastically contact the flexible strip.

[0013] Furthermore, both the flexible rack and the flexible strip are provided with weight-reducing grooves.

[0014] Optionally, the mechanism assembly further includes a massage head, the drive unit is connected to the massage head to drive the massage head to rotate, and the connection between the massage head and the drive unit is provided with a flexible joint so that the massage head fits against the back of the human body.

[0015] Optionally, the limiting channel has a clearance gap at the tooth position of the flexible rack.

Detailed Implementation

[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0028] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0029] The following is in conjunction with the appendix Figures 1-8 This invention provides a detailed description of a flexible massage mechanism, which includes a flexible rack 1 and a mechanism assembly 2.

[0030] Specifically, the movement assembly 2 has a housing 21 and a drive member disposed within the housing 21. The housing 21 defines a limiting channel 214 that is open on one side. The gear 23 of the drive member extends into the limiting channel 214 from the open portion of the limiting channel 214. The flexible rack 1 is slidably inserted into the limiting channel 214. The inner wall of the limiting channel 214 is provided with a first elastic protrusion 213 that can elastically contact the flexible rack 1. The flexible rack 1 is confined within the limiting channel 214 and meshes with the gear 23 so that when the gear 23 rotates, it can drive the movement assembly 2 to move along the length direction of the flexible rack 1.

[0031] In other words, the first elastic protrusion 213 in the limiting channel 214 is configured to elastically contact the flexible rack 1 in the limiting channel 214. This not only restricts the movement of the flexible rack 1 in the limiting channel 214, allowing the teeth of the flexible rack 1 to mesh with the teeth of the gear 23 of the mechanism assembly 2, but also provides the flexible rack 1 with elastic deformation space in the limiting channel 214. This allows the teeth of the flexible rack 1 to mesh with the gear 23 even when elastic deformation occurs, thus facilitating the movement of the entire mechanism assembly 2 up and down when the gear 23 rotates, and thus facilitating the massage head 22 on the mechanism assembly 2 to massage the back of the human body. The cross-sections of the flexible rack 1 and the limiting channel 214 can be square. The number of first elastic protrusions 213 can be multiple. Multiple first elastic protrusions 213 are spaced apart on the three inner walls of the limiting channel 214 except for the open part. The cross-section of the first elastic protrusion 213 can be semi-circular. Its arc surface can reduce the friction between the two when it contacts the flexible rack 1. The first elastic protrusion 213 can be made of rubber. The flexible rack 1 can be provided with two teeth that cooperate with the two limiting channels 214 provided on both sides of the housing 21.

[0032] Therefore, by means of a flexible rack 1 passing through the limiting channel 214 of the mechanism assembly 2 and engaging with the gear 23 of the mechanism assembly 2, the mechanism assembly 2 can move up and down under the rotation of the gear 23. This facilitates the up and down movement of the massage head 22 on the mechanism assembly 2 to massage the user's back. The first elastic protrusion 213 within the limiting channel 214 contacts the flexible rack 1, allowing the limiting channel 214 to enclose the flexible rack 1 and engage with the gear 23. Simultaneously, it provides space for the flexible rack 1 to deform, making the movement of the mechanism assembly 2 smoother, whether in a straight line or a curved path. This flexible massage mechanism has a simple structure, moves smoothly, and is beneficial for the user's massage experience.

[0033] Optionally, the flexible rack 1 is provided with a limiting strip 11 along its length, and the limiting channel 214 has a limiting groove 25 adapted to the limiting strip 11. Understandably, through the cooperation of the limiting strip 11 and the limiting groove 25, the relative distance between the teeth of the flexible rack 1 and the teeth of the gear 23 can be further limited, thereby ensuring that the flexible rack 1 and the gear 23 always remain in a meshing state. The limiting strip 11 can be located below the teeth of the flexible rack 1, and the cross-section of the limiting strip 11 and the limiting groove 25 can be square.

[0034] Optionally, the housing 21 includes a movement housing 211 and a first connector 212 detachably connected to the movement housing 211. A limiting channel 214 is disposed on the first connector 212, and a gear 23 is disposed on the movement housing 211. Understandably, the detachable connection between the first connector 212 and the movement housing 211 facilitates the installation of the flexible rack 1 and helps control manufacturing costs. The first connector 212 can be screwed to the bottom of the movement housing 211, and then connected to the movement housing 211 by a movement cover 215 plate, which improves the connection strength between the first connector 212 and the movement housing 211.

[0035] Optionally, the device also includes a flexible strip 3 disposed opposite to the flexible rack 1. The housing 21 has a sliding channel 216 disposed opposite to the limiting channel 214, and the flexible strip 3 is slidably inserted into the sliding channel 216. Understandably, the cooperation between the sliding channel 216 and the flexible strip allows the movement assembly 2 to be better supported, while avoiding the need for two flexible racks 1 and two gears 23 that cooperate with the flexible racks 1, which is beneficial for the miniaturization of the overall movement and for cost control.

[0036] Furthermore, the inner wall of the sliding channel 216 is provided with a second elastic protrusion 218 that can elastically contact the flexible strip 3. Understandably, the second elastic protrusion 218 facilitates the deformation of the flexible strip 3 and eliminates the gap between the flexible strip 3 and the sliding channel 216, making the sliding of the movement assembly 2 smoother. The second elastic protrusion 218 can have the same structure as the first elastic protrusion 213 described above. The second elastic protrusion 218 can be provided on the second connecting member 219, which is detachably connected to the housing 21. The second connecting member 219 and the housing 21 together construct a sliding channel 216 with a square cross-section.

[0037] Furthermore, both the flexible rack 1 and the flexible strip 3 are provided with weight-reducing grooves 12. Understandably, the weight-reducing grooves 12 significantly reduce the weight of the flexible rack 1 and the flexible strip 3, facilitating a lightweight design for the overall movement. This improves the flexibility of the flexible rack 1 and the flexible strip 3 while maintaining their strength. Multiple weight-reducing grooves 12 can be provided, with reinforcing ribs between each groove 12 to further enhance the strength of the flexible rack 1 and the flexible strip 3.

[0038] Optionally, the mechanism assembly 2 also includes a massage head 22. A drive unit connects to the massage head 22 to drive its rotation. A flexible connector 26 is provided at the connection between the massage head 22 and the drive unit to allow the massage head 22 to conform to the back of the user. Understandably, the flexible connector 26 at the connection between the massage head 22 and the drive unit allows the massage head 22 to rotate under the drive of the drive unit while simultaneously conforming to the back of the user, resulting in a more thorough massage. The flexible connector 26 can be a structure with metal or plastic ends and rubber in the middle, similar to a flexible connector in a pipe.

[0039] Furthermore, the limiting channel 214 has a clearance gap 217 at the tooth position of the flexible rack 1. Understandably, by setting the clearance gap 217, when the flexible rack 1 undergoes elastic deformation, the inner wall of the limiting channel 214 will not come into contact with the tooth of the flexible rack 1 and thus affect the relative movement between the movement assembly 2 and the flexible rack 1.
