DETAILED DESCRIPTION

[0045] Embodiment 1

[0046] Combine the following Figure 1-Figure 7 This embodiment is described in detail.

[0047] A multi-joint massage device is arranged on a massage chair frame to massage the front side of a human body, comprising a driving part, a massage part and a push rod 30 hinged at both ends to the driving part and the massage part, specifically:

[0048] The driving part includes a base 101, a first driving device, and a slide 102 slidably adapted to the base 101, the connecting end of the first driving device is hinged to the base 101, and the output end of the first driving device is connected to the slide 102 to drive the slide 102 to slide relative to the base 101;

[0049] The massage part includes a plurality of massage joints which are mutually transmission-connected, and the massage joints include at least a first massage joint 201 and a second massage joint 202 which are hinged to each other. The first massage joint 201 is hinged to the base 101, and one end of the push rod 30 is hinged to the slide 102, and the other end thereof is hinged to the first massage joint 201.

[0050] When in use, the first driving device drives the push rod 30 to move through the slide 102, and the push rod 30 acts on the massage part, thereby driving each massage section to move toward the human body to apply massage force. The force of each massage section is relatively concentrated, so that it can simulate the acupressure massage effect when massaging the user's chest, arms or other parts, thereby meeting the user's needs.

[0051] In this embodiment, the massage part further includes a second massage section 202 and a third massage section 203, and the first massage section 201, the second massage section 202 and the third massage section 203 are hinged in sequence; and further includes a small connecting rod 204 and a large connecting rod 205, the two ends of the small connecting rod 204 are hinged to the base 101 and the second massage section 202, and the two ends of the large connecting rod 205 are hinged to the first massage section 201 and the third massage section 203. Further, the first massage section 201, the second massage section 202 and the third massage section 203 are all connected with a massage plate 206, and each massage plate 206 presses on the user's body surface to form an arc-shaped massage surface convex outward, and the massage plate 206 is made of flexible silicone to avoid blunt pressure injury to the human body; or at least the arc-shaped surface part is made of flexible silicone.

[0052] In this embodiment, the mechanical diagram of the massage part is as follows: Figure 7 As shown, and as can be seen from the foregoing, the push rod 30 acts on the first massage joint 201, so the first massage joint 201 is equivalent to a driving member, and the motion chain formed by each massage joint, the small connecting rod 204 and the large connecting rod 205 is essentially a Watt motion chain. The Watt motion chain is one of the six-bar configurations with a degree of freedom of 1. Therefore, the Watt motion chain has a definite motion law, so that each massage joint reciprocates on a preset trajectory, thereby simulating acupressure massage effects.

[0053] In this embodiment, the first driving device includes a first motor 104, and the output end of the first motor 104 is provided with a screw 106, and the screw 106 is threadedly connected to the slide 102. It also includes a code disk 107 and a counter 108 that are adapted to each other, the code disk 107 is connected to the first driving device, and the counter 108 is connected to the slide 102. Further, the first driving device also includes a fixed seat 105, the code disk 107 is connected to the mounting seat, and the slide 102 is provided with a transmission seat 103, the screw 106 is threadedly adapted to the transmission seat 103, and the counter 108 is connected to the transmission seat 103. The first motor 104 drives the screw 106 to rotate clockwise or counterclockwise, thereby driving the slide 102 to move forward or backward, thereby driving each massage section to move within a preset trajectory. The code disk 107 is provided with a plurality of counting holes, and the counter 108 calculates the current moving distance through the counting holes. Its technical principle belongs to the prior art and will not be repeated here.

[0054] In this embodiment, the base 101 is provided with a slide groove, and the slide 102 is provided with a pulley 109 adapted to the slide groove.

[0055] The movement process of the multi-joint massage device proposed in this embodiment is as follows:

[0056] like Figure 6 As shown, the initial position of each massage section is as follows Figure 6The first motor 104 starts to drive the screw rod 106 to rotate, thereby driving the slide 102 to move, and then the push rod 30 pushes the first massage section 201, so that the second massage section 202 and the third massage section 203 move at the same time, as shown in position B; the first motor 104 continues to drive the slide 102 to move, and each massage section moves to the extreme position, as shown in position C. The first motor 104 reverses and drives each massage section to reset to the initial position, that is, position A.

[0057] The output direction of the first motor 104 is switched between forward rotation and reverse rotation, so that each massage section can move back and forth between the initial position and the limit position, thereby simulating the acupressure massage effect.

[0058] Embodiment 2

[0059] Combine the following Figure 8-Figure 14 This embodiment is described in detail.

[0060] In this embodiment, the first driving device is an inflatable and deflable airbag 401, which pushes the slide 102 to move when inflated; and further includes a return spring 404, one end of which is connected to the slide 102, and the other end of which is connected to the base 101. The use of the airbag 401 as the first driving device has a lower production cost than the first motor 104, thereby providing users with more choices and expanding its scope of application.

[0061] In this embodiment, a push plate 402 fixedly connected to the slide 102 and a fixed plate 403 fixedly connected to the base 101 are also included, and both ends of the return spring 404 can also be connected to the push plate 402 and the fixed plate 403, and the airbag 401 is located between the push plate 402 and the fixed plate 403. When in use, when the airbag 401 is inflated, the airbag 401 expands and pushes the push plate 402, so that the slide 102 slides relative to the base 101, thereby pushing each massage section in turn; when the airbag 401 is deflated, the pulling force of the return spring 404 pulls the slide 102 back through the push plate 402, thereby realizing that each massage section is reset to the initial position.

[0062] In this embodiment, the massage part includes a first massage joint 201, a second massage joint 202 and a third massage joint 203 which are hinged in sequence, and the first massage joint 201 is also hinged to the base 101; it also includes a small connecting rod 204 and a large connecting rod 205, one end of the large connecting rod 205 is hinged to the base 101, and the other end of the large connecting rod 205 is hinged to the third massage joint 203, the other end of the push rod 30 is hinged to the middle of the large connecting rod 205, and the two ends of the small connecting rod 204 are respectively hinged to the first massage joint 201 and the large connecting rod 205. Further, the first massage joint 201, the second massage joint 202 and the third massage joint 203 are integrally formed with an arc-shaped massage surface.

[0063] In this embodiment, the mechanical diagram of the massage part is as follows: Fig.14 As shown, and as can be seen from the foregoing, the push rod 30 acts on the large connecting rod 205, so the large connecting rod 205 is equivalent to a driving member, and the motion chain formed by each massage section, the small connecting rod 204 and the large connecting rod 205 is essentially a Stephenson motion chain. The Stephenson motion chain is one of another six-bar configurations with a degree of freedom of 1. The Stephenson motion chain has a definite motion law, so that each massage section reciprocates on a preset trajectory, thereby simulating acupressure massage effects.
