[0015] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0016] In combination with Figures 1-8 As shown in the drawings, the embodiment of the present application provides a massage core, which comprises a base plate 1, a main control device, a kneading assembly 2 and an ejection assembly 3 are arranged on the base plate 1, the kneading assembly 2 comprises a kneading shaft 21, a kneading driving device 22, a massage swing arm 23 and a massage head 24, the massage head 24 is arranged at the end of the massage swing arm 23, the kneading shaft 21 and the kneading driving device 22 are arranged on the base plate 1, the massage swing arm 23 is rotatably arranged on the kneading shaft 21, and the kneading driving device 22 drives the kneading shaft 21 to rotate to drive the massage swing arm 23 to perform kneading massage on a user.

[0017] One end of the ejection assembly 3 is connected to the base plate 1, and the other end of the ejection assembly 3 is connected to the middle region of the massage swing arm 23, the main control device controls the ejection assembly 3 to push the middle region of the massage swing arm 23, so that the massage swing arm 23 rotates around the kneading shaft 21 and the massage head 24 at the end of the massage swing arm 23 performs massage on the user.

[0018] That is, the present application realizes the massage force adjustment function and amplifies the stroke of the massage swing arm through a double-rocker 4-bar mechanism, provides a larger ejection distance in a limited space, and improves the user experience.

[0019] Further, in one example, as Figure 2As shown, the ejector assembly 3 includes a drive unit 31, a first segment 32, and a second segment. The drive unit 31 is disposed on the substrate 1. One end of the first segment 32 is rotatably connected to the substrate 1, and the other end of the first segment 32 is connected to one end of the second segment. The other end of the second segment is connected to the middle region of the massage arm 23. The drive unit 31 can drive the first segment 32 to rotate relative to the substrate 1, thereby pushing the massage arm 23 to rotate through the second segment. Specifically, the first segment 32 is an elongated structure, and the drive unit 31 is an inflatable airbag. After the drive unit 31 is inflated, it pushes the first segment 32 to rotate relative to the substrate 1. Specifically, the second segment includes a tapping motor 331, a tapping shaft 332, and a connecting rod 333. The tapping shaft 331 is connected to the other end of the first segment 32. The tapping shaft 332 is provided with an eccentric cam. One end of the connecting rod 333 is sleeved on the eccentric cam. The tapping motor 331 drives the tapping shaft 332 to rotate, thereby driving the massage arm 23 to reciprocate through the connecting rod 333. In a specific connection, the other end of the connecting rod 333 is provided with a universal ball joint, and the middle area of ​​the massage arm 23 is provided with a universal bushing. The other end of the connecting rod is connected to the universal bushing through the universal ball joint. Specifically, in one example, one end of the first segment 32 can be connected to the base plate 1 through a rotating shaft 4. Under the action of the drive unit 31, the first segment 32 is pushed to rotate relative to the base plate 1 with the rotating shaft 4 as the rotation center, so that the connecting rod 333 pushes the massage arm 23 to perform an outward and retracting action.

[0020] Furthermore, in order to achieve massage intensity adjustment while amplifying the stroke of the massage arm through a dual-rocker 4-bar linkage, and to provide a larger ejection distance within a limited space, in one example, such as... Figure 2 As shown, the first segment 32 is spaced apart from the kneading shaft 21 at the connection point with the substrate 1, and the sum of the lengths of the first segment 32 and the second segment is greater than the length of the massage arm 23. This allows the flip angle of the first segment 32 and the ejection angle of the massage arm 23 to increase exponentially, further providing a larger ejection distance in a smaller space and improving the user experience.

[0021] Specifically, such as Figure 3 The diagram shows a dual-rocker mechanism. One end of connecting rods CD and BE is fixed to base plate 1, while the other end is hinged to connecting rod BC. Connecting rod BE acts as the driving member, rotating around axis E. The other connecting rod AD swings accordingly, and point A at the end of connecting rod AD performs an arc-shaped ejection motion as shown by the dotted line. When rod EB moves to position EB', point A reaches point A', achieving the maximum required ejection amount. Rod EB' rotates in the opposite direction; when point B' reaches point B, point A' returns to point A, realizing the retraction action. As shown... Figure 1The connecting rod BE forms an angle of 26° with the horizontal direction, the connecting rod CD forms an angle of 40° with the horizontal direction, and the difference is 14°; and the connecting rod B'E forms an angle of 75° with the horizontal direction after ejection, and the connecting rod C'D forms an angle of 96° with the horizontal direction, and the difference is 21°, which indicates that the connecting rods BE and CD are not increased equally, but the ejection angle is exponentially increased with the increase of the rotation angle.

[0022] The Figure 3 double-rocker mechanism is evolved into the movement structure as shown in Figure 4 and Figure 5 , wherein point A is the massage head 24, point B is the knocking shaft 332, point C is the universal shaft sleeve support point (i.e. the universal ball socket), point D is the kneading shaft 21, point E is the rotating shaft 4, the connecting rod AD is the massage swing arm 23, the BE point is the first section 32, and the BC rod is the connecting rod 333; the specific action is that the inflatable air bag 31 is inflated to lift the first section 32, and the first section 32 is hinged to the rotating shaft 4, so that the first section 32 is rotated around the rotating shaft 4 while being lifted, and the connecting rod 333 is respectively hinged to the knocking shaft 332 and the universal shaft sleeve support point C, so that the massage swing arm 23 is lifted. As shown in Figure 6 , the angle between the massage swing arm 23 and the horizontal plane is increased by an unequal amount with the increase of the angle between the first section 32 and the horizontal plane, and the increase rule is that the angle of the next amplification is the sum of the angles of the previous two amplifications, i.e. x n+1 =x n +x n-1 , so that the lifting stroke is amplified. The existing 3D lifting structure is basically rotated around a certain rotation support point, and the rotation angle is equal to the rotation angle provided by the power source.

[0023] The stroke amplification rule can be shown in the following table:

[0024]

[0025] That is to say, the 3D lifting stroke amplification is realized by the 4-connecting-rod mechanism of the double-rocker, a larger lifting distance is realized in a limited space, and the user experience is improved.

[0026] It should be noted that the lifting is realized by the inflatable air bag in the technical scheme of the present application, so that the massage is not too stiff, the flexible massage effect is achieved, and the user experience effect is better.

[0027] The inflatable air bag is further provided with a pressure detector, and the main control device is electrically connected with the pressure detector. The pressure value detected by the pressure detector can be used to timely adjust the lifting amount, so as to provide better user experience for the user.

[0028] Further, in one example, in order to enrich the technical solution of the massage core provided by the present application, the ejection assembly can also have different implementation schemes, specifically, as shown in Figure 7 The driving part 31 includes a telescopic driving shaft 51, a sector gear 52, a telescopic driving motor device 53 and a telescopic gear 54. The telescopic driving shaft 51 is arranged on the base plate 1. The telescopic gear 54 is arranged on the telescopic driving shaft 51. One end of the sector gear 52 is rotatably arranged on the base plate 1. The other end of the sector gear 52 is engaged with the telescopic gear 54. The telescopic driving motor device 53 is connected with the telescopic driving shaft 51.

[0029] The telescopic driving motor device 53 drives the telescopic driving shaft 51 to rotate, so as to drive the telescopic gear 54 to rotate, and the sector gear 52 engaged with the telescopic gear 54 pushes the first section 32 to rotate relative to the base plate 1.

[0030] Similarly, in one example, as shown in Figure 8 The driving part 31 includes a push rod device 61 and a connecting rod 62. The push rod device 61 is arranged on the base plate 1. One end of the connecting rod 62 is hingedly connected with the push rod device 61. The other end of the connecting rod 62 is hingedly connected with the other end of the first section 32.

[0031] The push rod device 61 is telescopic, so as to drive the connecting rod 62 to push the first section 32 to rotate relative to the base plate 1.

[0032] Further, in one example, as shown in Figure 2 Further, in one example, as shown in The first walking shaft 7 is provided with a gear reduction box 71. The gear reduction box 71 is engaged with the gear 9 arranged on the kneading shaft 21. When the kneading driving device 22 drives the kneading shaft 21 to rotate, the gear 9 drives the gear reduction box 71 to rotate, so as to drive the first walking shaft 7 to rotate. The kneading and walking massage actions are realized by one kneading motor. Thus, the kneading, knocking and walking massage actions can be realized by two motors according to the technical solution of the present application, so as to reduce the cost of one motor, and the production cost is low and the processing is simple.

[0033] Further, the present application also provides a massage chair, which comprises the massage core and a chair frame. The main control device controls the massage core to move up and down on the chair frame.

Therefore, the appended claims are intended to be interpreted as including all the changes and modifications falling within the scope of the present application.

[0035] Obviously, numerous modifications and variations of the present application are possible in light of the above teachings. It is therefore to be understood that within the scope of the appended claims and their equivalents, the application can be practiced otherwise than as specifically described.
