Description

Technical Field

[0001] This utility model relates to the field of massage equipment technology, and in particular to a shoulder massage mechanism and a massage chair. Background Technology

[0002] Shoulder massage mechanisms on massage chairs typically use airbags to press directly on the shoulders. In this structure, the airbags are fixed in place, and the switching between the inactive and active states of the shoulder massage mechanism relies entirely on the inflation and deformation of the airbags. Arms and buttocks can directly utilize airbag massage mechanisms, either because the user's weight ensures good contact with the massage mechanism in areas like the buttocks, or because areas like the arms are more flexible and easily achieve good contact. Unlike these areas, the shoulders have limited mobility and cannot rely on the user's weight for effective contact. Therefore, existing shoulder massage mechanisms using airbags cannot achieve a satisfactory shoulder massage effect. Utility Model Content

[0003] In a first aspect, this utility model provides a shoulder massage mechanism, including a massage airbag assembly. The massage airbag assembly is mounted on a movable base plate, which is driven to swing by a swing assembly. The swing assembly includes a swing arm, a drive assembly, and a base. The first end of the swing arm is rotatably mounted on the base. The movable base plate and the first end of the swing arm are fixedly connected. The second end of the swing arm is provided with a groove. The drive assembly drives a rotating component to rotate. The rotating component is provided with a drive rod. The rotation centers of the drive rod and the rotating component are eccentrically set. The drive rod is slidably inserted into the groove of the swing arm.

[0004] In an optional implementation, the swing assembly further includes a swing stroke control mechanism.

[0005] In an optional embodiment, the swing stroke control mechanism includes an encoder that rotates synchronously with the rotating component. The encoder has a light-transmitting groove. The swing stroke control mechanism also includes a photoelectric sensor, which includes a transmitter and a receiver, which are respectively located on both sides of the light-transmitting groove.

[0006] In an optional implementation, the light-transmitting groove is arc-shaped.

[0007] In an alternative embodiment, the swing arm includes a removable slide plate with a slide groove disposed on it.

[0008] In an optional embodiment, the swing arm includes a swing base plate, the swing base plate is provided with a mounting groove, the slide plate includes a panel and a slide portion, the slide portion protrudes from the panel, the slide is provided in the slide portion, and the slide portion passes through the mounting groove.

[0024] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0025] This embodiment provides a shoulder massage mechanism, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the device includes a massage airbag assembly, which is mounted on a movable base plate 100. The movable base plate 100 is driven to swing by a swing assembly, which includes a swing arm 210, a drive assembly 220, and a base 270. The first end of the swing arm 210 is rotatably mounted on the base 270. The movable base plate 100 and the first end of the swing arm 210 are fixedly connected. The second end of the swing arm 210 is provided with a groove 211. The drive assembly 220 drives a rotary member 230 to rotate. The rotary member 230 is provided with a drive rod 231. The rotation centers of the drive rod 231 and the rotary member 230 are eccentrically set. The drive rod 231 is slidably inserted into the groove 211 of the swing arm 210.

[0026] in, Figure 1 This is a three-dimensional structural diagram of the shoulder massage mechanism provided in this embodiment in its closed state. Figure 2 This is a front view of the shoulder massage mechanism provided in this embodiment in its closed state. Figure 3 This is one of the structural schematic diagrams of the swing component of the shoulder massage mechanism provided in this embodiment in the closed state. Figure 4 This is the second schematic diagram of the swing component of the shoulder massage mechanism provided in this embodiment in the closed state. Figure 3 and Figure 4 The structure of the oscillating component is shown from different perspectives. Figure 6This is a frontal view of the shoulder massage mechanism provided in this embodiment in its open state.

[0027] Shoulder massage mechanism in closed state, such as Figure 2 As shown, in its working state, the shoulder massage mechanism is in the open position as follows: Figure 6 As shown, this indicates the non-working state. Figure 2 and Figure 6 These are all front-view diagrams, clearly showing the positional changes of the active base plate 100 and the massage direction of the massage airbag assembly. Figure 2 and Figure 6 Massages downwards from the active base plate 100, and the massage airbag assembly is mounted on the active base plate 100. Figure 2 and Figure 6 None of them are shown in the middle, in Figure 2 and Figure 6 In the closed state, the user's shoulder is located below the movable base plate 100. When the shoulder massage mechanism is closed, the movable base plate 100 is closer to the user's shoulder; when the mechanism is open, it is further away from the user's shoulder.

[0028] The shoulder massage mechanism provided in this embodiment uses a swing component to drive the movable base plate 100 to swing. In the non-working state, the swing component can drive the movable base plate 100 away from the user's shoulder position, which facilitates the user's shoulder movement and makes it easier for the user to sit in and get out of the massage chair. In the working state, the swing component can drive the movable base plate 100 closer to the user's shoulder position, so that the massage airbag component is closer to the user's shoulder. The massage airbag component can achieve a better contact effect with the user's shoulder and provide a better massage experience.

[0029] This embodiment also provides a massage chair, including the shoulder massage mechanism described above.

[0030] In this embodiment, the structure of the oscillating component is as follows: Figure 3 and Figure 4 As shown, when the drive assembly 220 is working, it drives the rotating component 230 to rotate. Since the rotation centers of the drive rod 231 and the rotating component 230 are eccentrically set, the drive rod 231 will perform circular motion as the rotating component 230 rotates. Since the drive rod 231 is slidably inserted into the groove 211 of the swing arm 210, the groove 211 is located at the second end of the swing arm 210, and the first end of the swing arm 210 is rotatably mounted on the base 270, the drive rod 231 will drive the swing arm 210 to swing when it moves, and the swing arm 210 will in turn drive the movable base plate 100 fixedly connected to it to swing.

[0031] In this embodiment, the swing assembly further includes a swing stroke control mechanism, thereby causing the swing assembly to reciprocate within an adjustable stroke. In other embodiments, the swing assembly may also employ a fixed stroke swing.

[0032] like Figure 4 As shown, in this embodiment, the swing stroke control mechanism includes an encoder 240 that rotates synchronously with the rotary component 230. The encoder 240 has a light-transmitting groove 241. The swing stroke control mechanism also includes a photoelectric sensor, which includes a transmitter 251 and a receiver 252, respectively located on both sides of the light-transmitting groove 241. The light-transmitting groove 241 can be a hollow structure or have a light-transmitting material installed on it. The photoelectric sensor's transmitting end 251 emits a photoelectric signal. When the light-transmitting groove 241 is between the transmitting end 251 and the receiving end 252 of the photoelectric sensor, the receiving end 252 can receive the signal. When the encoder 240 rotates, causing the light-transmitting groove 241 to rotate away from the middle of the transmitting end 251 and the receiving end 252 of the photoelectric sensor, the receiving end 252 of the photoelectric sensor cannot receive the signal. By utilizing the signal change of the photoelectric sensor, the drive component 220 can be controlled. For example, when the photoelectric sensor changes from having a signal to having no signal, the drive component 220 reverses, and the encoder 240 moves in the opposite direction. In this way, the encoder 240 always moves within the position range that keeps the light-transmitting groove 241 between the transmitting end 251 and the receiving end 252 of the photoelectric sensor, and the swing component does not need to complete its full stroke according to its structural design. By setting multiple sets of photoelectric sensors and multiple light-transmitting grooves 241 and selecting control signals, the swing stroke of the swing mechanism can be adjusted and controlled, thereby adapting to the usage needs of different massage chairs.

[0033] In this embodiment, the light-transmitting groove 241 is arc-shaped. In other embodiments, the light-transmitting groove 241 can also be other curved shapes or rectangular shapes, etc.

[0034] like Figure 5 As shown, in this embodiment, the swing arm 210 includes a detachable slide plate 212, with a slide groove 211 disposed on the slide plate 212. The swing arm 210 includes a swing base plate 215, which has a mounting groove 216. The slide plate 212 includes a front panel 213 and a slide groove portion 214, which protrudes from the front panel 213. The slide groove 211 is disposed on the slide groove portion 214, and the slide groove portion 214 passes through the mounting groove 216. The front panel 213 and the swing base plate 215 of the slide plate 212 are connected by bolts. Figure 5 An exploded view of the swing arm 210 and the rotating component 230 in the swing assembly of the shoulder massage mechanism provided in the embodiment of this utility model in the closed state.

[0035] During the swinging process of the swing assembly, the drive rod 231 and the slide 211 are always in a state of friction. The slide 211 is mounted on a removable slide plate 212. The slide plate 212 can be replaced after excessive wear due to friction, or a more wear-resistant material can be used, thereby improving the wear resistance of the swing arm 210. Therefore, the removable slide plate 212 can extend the service life of the swing arm 210. The slide plate 212 enters the mounting groove 216 of the swing base plate 215 through the protruding slide portion 214, achieving a better positioning effect. Furthermore, the bolted connection between the panel 213 of the slide plate 212 and the swing base plate 215 facilitates the replacement of the slide plate 212.

[0036] like Figure 3 As shown, in this embodiment, the swing assembly includes a rotating shaft 260, which is rotatably mounted on the base 270. The first end of the swing arm 210 is connected to the rotating shaft 260. A connecting structure such as a bearing can be provided between the rotating shaft 260 and the base 270. Furthermore, the longer rotating shaft 260 can provide mounting space for the movable base plate 100. One end of the movable base plate 100 can be connected to the swing arm 210, and the other end can be connected to the rotating shaft 260, thereby enabling the movable base plate 100 to achieve a more stable swing effect.

[0037] In this embodiment, as Figure 4 As shown, the drive assembly 220 includes a drive motor 221 and a reducer 222. The output shaft of the reducer 222 is connected to the rotary component 230. At the same time, the encoder 240 is also connected to the output shaft of the reducer 222. The reducer 222 drives the rotary component 230 and the encoder 240 to rotate synchronously.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
