Description

Technical Field

[0002] Currently, existing massage chairs, massage beds, massage sofas, etc. generally use walking massage mechanisms to massage the human body. Moreover, the walking path of the massage mechanism is restricted by the rail track, and the massage range of most massage chairs is generally between the user's buttocks and the back of the neck. At this time, it is necessary to ensure that the massage mechanism can massage each point between the buttocks and the back of the neck to meet the comfort requirements of the user.

[0003] After retrieval, a Chinese patent with the application number 201810509747.8 discloses a walking track for a massage mechanism, including a guide rail. The guide rail includes a first guide rail and a second guide rail respectively fixedly arranged on a seat frame and a back frame. The first guide rail and the second guide rail are connected by a third guide rail. The third guide rail is a flexible guide rail that can be bent and deformed in the length direction, and the third guide rail is integrally formed with the first guide rail and the second guide rail; the third guide rail is supported on a flexible connecting plate that can be deformed in the length direction, and the flexible connecting plate is connected between the seat frame and the back frame; at least two convex columns are arranged at intervals on the back surface of the third guide rail, and the flexible connecting plate is also provided with a limit hole for accommodating the convex columns. The limit hole is an oval hole, and the limit hole and the convex column are loosely fitted so that the convex column can slightly slide in the limit hole after the third guide rail is deformed when adjusting the angle.

Moreover, since the travel screw 15 and the linkage part 16 are both located on the plane of the frame structure, the entire linear travel frame 1 is a flat plane structure as a whole, which is small in size and occupies less internal space of the sofa, and is very practical.

[0042] The adjustable scissors structure 2 includes a movement chassis 26, wherein the running wheels include a first roller 261 located on both sides of the front end of the movement chassis 26 and a second roller 263 located on both sides of the rear end of the movement chassis 26, the first roller 261 is connected to the side of the movement chassis 26 through a first rotating shaft 262, and the second roller 263 is connected to the side of the movement chassis 26 through a second rotating shaft 264.

[0044] Moreover, the fixing bracket includes a square sleeve 162 and multiple reinforcing plates 163. The periphery of the internal thread sleeve 161 is fixedly connected to the inner peripheral wall of the square sleeve 162 through multiple reinforcing plates 163.

Among them, there are four reinforcing plates 163, and the four reinforcing plates 163 are respectively vertically connected to the four inner side walls of the square sleeve 162, and the four reinforcing plates 163 are arranged in a "cross" shape. The linkage part 16 designed as above has a simple and firm structure, is convenient to install, and is not easily deformed by force.

[0045] In this embodiment, the traveling power part 17 includes a speed reduction and direction change gearbox 171 and a traveling brushless motor 172. The output end of the speed reduction and direction change gearbox 171 is connected to the end of the traveling lead screw 15, and the output shaft of the traveling brushless motor 172 is connected to the input end of the speed reduction and direction change gearbox 171. Among them, the output shaft of the traveling brushless motor 172 is vertically arranged with the traveling lead screw 15, and the maximum thickness of the traveling power part 17 does not exceed 2.5 times the thickness of the square frame structure.

Moreover, both ends of the front end plate 13 are provided with first connecting pieces 131, and both ends of the rear end plate 14 are provided with second connecting pieces 141. The first connecting pieces 131 and the second connecting pieces 141 are fixedly connected to the ends of the guide rail 12 through multiple groups of bolts. The square frame structure designed as above has a simple and stable structure, is convenient to assemble, and is not easily deformed or damaged.

[0047] In this embodiment, the adjustable scissors structure 2 further includes two sets of scissors forks 21, an adjustment driving part 22 and a guide block 23. The middle parts of the scissors forks 21 are hinged, and the four corners form a first moving point, a second moving point, a third moving point and a fourth moving point. The two sets of scissors forks 21 are respectively located on the opposite sides of the bottom tray 3.

The adjustment driving part 22 is installed on the movement chassis 26 and drives the sliding plate 266 to slide back and forth.

[0048] The adjustable scissors structure 2 designed above has a simple structure and stable operation. When the first moving point and the third moving point move to the end limit positions of the linear walking frame 1, the adjustment driving part 22 can be started, and then drive the sliding plate 266 and the second rotating shaft 264 to approach the first moving point (that is, the adjustable scissors structure 2 contracts), thereby driving the adjustment column 211 to slide in the linear groove 31 and the inclined groove 32 in sequence, and then the three working states in Figure 3 、 Figures 4 to 5 can be gradually realized, and it has a better massage effect.

[0049] In order to improve the stability of the entire system during operation, the adjustable scissors structure 2 further includes a bent plate 24 fixed to one side of the front end of the movement chassis 26. A buffer spring 25 arranged along the sliding direction of the adjustable scissors structure 2 is fixed on the outer side of the bent plate 24. When the adjustable scissors structure 2 gradually slides to the end limit position of the linear walking frame 1, the end of the buffer spring 25 away from the bent plate 24 abuts against the rear end plate 14. A guide wire 11 penetrating the bent plate 24 and the buffer spring 25 is also provided between the front end plate 13 and the rear end plate 14.

[0050] Through the adjustable scissors structure 2 designed with the above structure, it can at least realize driving the bottom tray 3 to move to the above three dynamic working positions, and by pre-customizing the lengths of the inclined groove 32 and the linear groove 31 and the inclination angle of the inclined groove 32, the massage limit position and the massage force magnitude of the massage unit 5 can be controlled.

The DC brushless motor 221 is installed on the movement chassis 26 and is located at the rear end of the movement chassis 26. The DC brushless motor 221 is drivingly connected to the adjustment lead screw 222. The adjustment driving part 22 designed as above has a simple structure, stable operation, simple and precise control.

[0052] In order to reduce the noise generated during the sliding process of the adjustment column 211, the bottom tray 3 is a metal part, and plastic spacer sleeves 33 are provided on the inner peripheral walls of the inclined slots 32 and the linear slots 31. The plastic spacer sleeves 33 are in direct contact with the adjustment column 211.

[0053] In this embodiment, there are two groups of massage units 5, and the two groups of massage units 5 are respectively located on opposite sides of the massage power part 4. The massage power part 4 includes a massage brushless motor 41 and a massage gearbox 42. Power output ends are respectively provided on both sides of the massage gearbox 42. The output shaft of the massage brushless motor 41 is connected to the input end of the massage gearbox 42. The two power output ends of the massage gearbox 42 are respectively connected to the two groups of massage units 5. The massage unit 5 includes a swinging fork arm 51 and two massage wheels 52. The bottom of the swinging fork arm 51 is rotatably connected to the bottom tray 3. The top of the swinging fork arm 51 has two rotation holes, and the two massage wheels 52 are respectively rotationally assembled in the rotation holes.

[0054] The massage unit 5 and the massage power part 4 designed as above have a simple structure and stable operation, simple and precise control, and have a good massage effect during the swinging process. The massage actions include a series of complex actions such as kneading and knocking. At the same time, the present invention can also adaptively adjust the massage angle according to the human body posture.

[0055] The beneficial technical effects of the dynamic massage device with a scissor structure in the embodiments of this application are roughly as follows:

[0056] Starting the power part of the linear walking frame 1 (i.e., the traveling power part 17) can drive the adjustment scissor structure 2 to move linearly, that is, it can move back and forth between the user's buttocks and the back of the neck. For the non-planar curved surface structure between the buttocks and the back of the neck, by starting the adjustment scissor structure 2, the bottom tray 3 is moved to multiple dynamic working positions, and the massage power part 4 is started to drive the massage unit 5 to swing reciprocally, especially suitable for the deeper massage positions at the back of the neck. It comprehensively realizes the dynamic massage effects at multiple different curved surface positions. And because the linear walking frame 1 is a linear motion structure with a simple structure, it has a small installation difficulty, a small installation space, is not easily damaged, and has a low maintenance difficulty.

[0057] The above are only the preferred embodiments of the present application and are not intended to limit the present application.
