Description

Technical Field

[0001] The utility model relates to the technical field of massage chairs, and specifically relates to a folding structure of a base plate of a massage chair manipulator. Background Art

[0002] In the "matrix vibration manipulator" proposed in view of the brittle bones of the elderly, in order to ensure that the matrix massage manipulator on the massage chair needs to walk on the S-shaped guide rail, its base plate needs to be adaptively bent along with the S-shaped guide rail. However, although the existing base plate can achieve the bending effect, the driving torque of the transmission shaft cannot be positively transmitted after bending, so that the transmission force can be transmitted to the manipulator after bending, so that the normal transmission of the manipulator can be realized at different bending angles.

[0003] The existing utility model patent with the patent number 201810035215.5 relates to a floating massage device, which includes a track frame and a massage mechanism. One end of the base plate of the massage mechanism is provided with a driving shaft, and the other end is provided with a following shaft; track wheels are arranged at both ends of the driving shaft and the following shaft, and the track wheels are slidably positioned on the tracks on both sides of the frame by means of the track wheels; a gear is further arranged on the side of a pair of track wheels of the driving shaft, and the gear meshes with the rack on the side of the track, and the gear is driven by the power on the massage mechanism to reciprocate up and down along the track; the feature is that: a floating mechanism is arranged between the following shaft and the base plate, and one end of the massage mechanism is lifted by means of the floating mechanism. Driven by the floating mechanism, the massage mechanism of the utility model can float to a greater extent, can not only touch the more sunken cervical vertebrae and waist, but also has a gentle finger pressure function. Cooperating with the walking drive, it can not only perform fixed-point finger pressure, but also perform walking sand scraping. By combining massage mechanisms with different functions, more diverse massage means can be realized.

[0004] However, although this patent realizes floating massage, it cannot bend the base plate to better fit the human body arc. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a folding transmission structure of a base plate, which can be bent when walking on the S-shaped track of a massage chair, so as to realize a manipulator massage that better fits the human back, aiming at the above-mentioned deficiencies of the prior art.

[0006] To achieve the above object, the following technical solution is adopted. A folding structure of a manipulator bottom plate of a massage chair includes a bottom plate and two drive shafts for the manipulator. A folding structure is provided on the bottom plate. The bottom plate is divided into a first bottom plate and a second bottom plate along the folding structure. The second bottom plate is rotatably arranged on one side of the first bottom plate through the folding structure. Each group of drive shafts includes a first drive shaft and a second drive shaft that are connected to each other at the folding structure. A folding component for folding the drive shafts is provided at the connection end of the first drive shaft and the second drive shaft. The first drive shaft is rotatably arranged on the first bottom plate, and the second drive shaft is rotatably arranged on the second bottom plate. When the first bottom plate and the second bottom plate are folded through the folding structure, the first drive shaft and the second drive shaft are synchronously folded through the folding component.

[0007] Adopting the above technical solution, since the guide rail of the massage chair has a certain curvature and the human back also has a certain curvature, in order to make the contact area between the manipulator on the bottom plate and the human body larger and the contact closer, the bottom plate needs to be able to fold. When the first bottom plate and the second bottom plate are on the same horizontal plane, the first drive shaft and the second drive shaft are on the same axis. When the bottom plate bends through the folding structure along with the S-shaped guide rail of the massage chair, at this time, the first drive shaft and the second drive shaft also fold in the same direction and at the same angle as the bottom plate through the folding component. Since it is necessary to make the massage manipulator driven on the drive shaft also fold and massage when the bottom plate folds, the folding of the bottom plate will not affect the transmission through the same-direction synchronous folding of the drive shaft and the bottom plate, thus realizing the manipulator massage that adapts to the S-shaped guide rail and fits the human body better.

[0008] A folding structure of a manipulator bottom plate of a massage chair can be further set as follows: The folding component includes a universal joint connecting piece arranged between the first drive shaft and the second drive shaft; a first rotating groove arranged on the first drive shaft for placing the universal joint connecting piece; a second rotating groove arranged on the second drive shaft at a position perpendicular to the first rotating groove.

[0009] Adopting the above technical solution, the first drive shaft and the second drive shaft are directly connected through the universal joint connecting piece. The first drive shaft realizes multi-angle folding along with the folding angle of the bottom plate through the first rotating groove and the second rotating groove. The first drive shaft can be rotatably connected and limited to the first bottom plate through a bearing, and the second drive shaft can be rotatably connected and limited to the second bottom plate through a bearing. Therefore, when the bottom plate folds, the second drive shaft realizes folding through the universal joint connecting piece without affecting the transmission at both ends. The first rotating groove and the second rotating groove can also be set to be U-shaped, so as not to affect multi-angle folding, and at the same time, the torque of the first drive shaft and the second drive shaft can be normally transmitted.

[0010] A folding structure of a manipulator bottom plate of a massage chair can be further configured as follows: A first positioning pin is provided in the vertical direction of the first transmission shaft in the first rotating groove, passing through the universal joint connector and abutting against the outer wall of the first transmission shaft at both ends. A second positioning pin is provided at the vertical position of the second transmission shaft in the second rotating groove, with both ends inserted into and limiting the universal joint connector.

[0011] With the above technical solution, the insertion positions of the first positioning pin and the second positioning pin are perpendicular to each other. Therefore, the first positioning pin can be in two sections to insert the universal joint connector for limiting at both ends, while the second positioning pin can be in one section and directly pass through the universal joint connector. Therefore, the first positioning pin and the second positioning pin will not affect each other's insertion when positioning the universal joint connector, enabling the first transmission shaft and the second transmission shaft to be folded at multiple angles, and at the same time, it will not affect the torque transmission between the first transmission shaft and the second transmission shaft.

[0012] A folding structure of a manipulator bottom plate of a massage chair can be further configured as follows: The folding structure includes a notch provided on one side of the first bottom plate and a boss provided on one side of the second bottom plate. The boss is placed in the notch, and connecting plates are provided on both sides. A limit pin is inserted and fixed through the connecting plates. Limiting plates parallel to the connecting plates are provided on both sides of the boss, and arc-shaped grooves are formed on the limiting plates. The limit pin passes through the arc-shaped grooves and moves along the trajectory of the arc-shaped grooves.

[0013] With the above technical solution, by matching the first bottom plate and the second bottom plate through the notch and the boss, and the limit pin makes a circular arc folding along the trajectory of the arc-shaped groove, the folding is more gentle compared to directly hinging and rotating the two. The backs of the elderly are not suitable for sudden and rapid folding, but are suitable for this relatively gentle folding. If the first bottom plate and the second bottom plate are directly hinged, they will directly rotate upward or downward during rotation, which will cause discomfort to the human back. However, in this application, the first bottom plate and the second bottom plate move along the trajectory of the arc-shaped groove through the limit pin, so that the bottom plate rotates to form an arc, and will not directly bend to cause discomfort to the human body. The rotation is made more gentle through the limit pin and the arc-shaped groove, making it more suitable for the backs of the elderly.

[0014] A folding structure of a manipulator bottom plate of a massage chair can be further configured as follows: A horizontal groove and a vertical groove are provided between the boss and the notch. The connecting plates are vertically provided on both sides of the notch and are parallel to the vertical groove. The limiting plates are vertically provided on both sides of the boss and are parallel to the connecting plates.

[0015] With the above technical solution, through the transverse groove and the vertical groove, there is always a certain gap between the notch of the first bottom plate and the boss of the second bottom plate during rotation, so that the rotation is more gentle. By making the connecting plate perpendicular to the first bottom plate and the limiting plate perpendicular to the second bottom plate, and the connecting plate and the limiting plate are arranged in parallel, the positions of the first bottom plate and the second bottom plate are restricted, so that the rotation is more stable. And the limiting pin can be just fixed on the connecting plate, and the limiting pin makes a gentle winding movement in the arc groove. Description of the Drawings

Detailed Description of the Invention

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0026] Embodiment: As Figures 1-8A folding structure of a manipulator bottom plate of a massage chair is shown, which includes a bottom plate 1 and two drive shafts 2 for the transmission manipulator. A folding structure 3 is provided on the bottom plate 1. The bottom plate 1 is divided into a first bottom plate 11 and a second bottom plate 12 along the folding structure 3. The second bottom plate 12 is rotatably arranged on one side of the first bottom plate 11 through the folding structure 3. The folding structure includes a notch 111 provided on one side of the first bottom plate 11 and a boss 112 provided on one side of the second bottom plate 12. The boss 112 is placed in the notch 111 and connecting plates 113 are provided on both sides. A limit pin 116 is fixedly inserted through the connecting plates 113. Limit plates 115 parallel to the connecting plates 113 are provided on both sides of the boss 112. An arc-shaped groove 114 is formed on the limit plate 113. The limit pin 116 passes through the arc-shaped groove 114 and moves along the trajectory of the arc-shaped groove 114. A horizontal groove 117 and a vertical groove 118 are provided between the boss 112 and the notch 111. The connecting plates 113 are vertically arranged on both sides of the notch 111 and are parallel to the vertical groove 118. The limit plates 113 are vertically arranged on both sides of the boss 112 and are parallel to the connecting plates 113. By providing the horizontal groove 117 and the vertical groove 118 between the notch 111 and the boss 112, a connection gap is formed between the two, so that when folding, the slow folding of the bottom plate 1 is realized through the cooperation of the limit pin 116 and the arc-shaped groove 114, making the folding amplitude and strength of the bottom plate 1 more suitable for the elderly. Each group of drive shafts 2 includes a first drive shaft 21 and a second drive shaft 22 that are connected to each other at the folding structure 3. A folding assembly 5 for folding the drive shaft 2 is provided at the connection end of the first drive shaft 21 and the second drive shaft 22. The first drive shaft 21 is rotatably arranged on the first bottom plate 11. The second drive shaft 22 is rotatably arranged on the second bottom plate 12. The first drive shaft 21 is rotatably arranged on the first bottom plate 11. The second drive shaft 22 is rotatably arranged on the second bottom plate 12. While the first bottom plate 11 and the second bottom plate 12 are folded through the folding structure 3, the first drive shaft 21 and the second drive shaft 22 are synchronously folded through the folding assembly 5. The folding assembly 5 includes a universal joint connector 51 provided between the first drive shaft 21 and the second drive shaft 22; a first rotating groove 52 provided on the first drive shaft 21 for placing the universal joint connector 51;A second rotating groove 53 is provided on the second transmission shaft 22 at a position perpendicular to the first rotating groove 52. The shapes of the first rotating groove 52 and the second rotating groove 53 can be set as U-shaped. A first positioning pin 54 is provided on the first transmission shaft 21 in the vertical direction of the first rotating groove 52. The first positioning pin 54 passes through the universal joint connector 51 and its two ends abut against and limit the outer wall of the first transmission shaft 21. A second positioning pin 55 is provided on the second transmission shaft 22 at a position perpendicular to the second rotating groove 53. The two ends of the second positioning pin 55 are inserted into and limit the universal joint connector 51. When the bottom plate 1 reaches the S-shaped bending part of the massage chair guide rail, the first bottom plate 11 and the second bottom plate 12 move in the arc-shaped groove 114 through the limit pin 116 to form a soothing type of folding. At the same time, the first transmission shaft 21 and the second transmission shaft 22 also perform folding in the same direction and at the same angle as the bottom plate 1 through the universal joint connector 51, and it does not affect the torque transmission at both ends of the transmission shaft 2. Since the guide rail of the massage chair has a certain curvature and the human back also has a certain curvature, in order to make the contact area between the manipulator on the bottom plate 1 and the human body larger and the contact closer, the function of folding the bottom plate 1 is required. When the first bottom plate 11 and the second bottom plate 12 are on the same horizontal plane, the first transmission shaft 21 and the second transmission shaft 22 are kept on the same axis. When the bottom plate 1 folds along the folding structure 3 following the S-shaped guide rail of the massage chair, at this time, the first transmission shaft 21 and the second transmission shaft 22 also fold along the folding structure 3 and through the folding assembly 5 in the same direction and at the same angle as the bottom plate 1. Since it is necessary to make the massage manipulator on the transmission shaft 2 fold during the folding of the bottom plate 1, the folding of the bottom plate 1 does not affect the transmission through the same-direction and synchronous folding of the transmission shaft 2 and the bottom plate 1, so as to achieve the manipulator massage that adapts to the S-shaped guide rail and fits the human body more closely.;

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
