[0025] The following describes some embodiments of the present invention in detail with reference to the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.

[0026] Combine Figure 1The massage core of the present application can be used in a massage chair. The massage core is installed on the body and can be controlled to move on the body to move between the user's waist and back. It should be understood that the massage core of the present application can also be applied to other massage machines, such as vertical massage machines or wall-mounted massage machines. Figures 2 to 13 In one embodiment, the massage movement of the present application includes a frame 1, a massage device 2, a travel drive device 3, a forward tilt adjustment device 4, and a body pressure detection device 5. The control mechanism of the massage movement is omitted in the figure, and the control mechanism is installed on the frame 1, for example.

[0027] [Frame] The frame 1 is roughly in the shape of a square frame, and the massage device 2, the travel drive device 3, the forward tilt adjustment device 4, and the body pressure detection device 5 are installed on the frame 1. The upper side beam of the frame 1 is provided with a mounting portion 1A. Figure 6 Mounting portion 1A is equipped with a position detector Q11, which is electrically connected to the massage mechanism's control mechanism (not shown). The right beam of frame 1 has a travel position detector Q21, which cooperates with the displacement sensing element on the body to assist in determining the massage mechanism's position within the body.

[0028] [Massage Device] The massage device 2 includes a support frame P0, a massage arm P1, a kneading drive mechanism P2, and a percussion drive mechanism P3. The support frame P0 is rotatably connected to the lower travel shaft 3B. In this embodiment, the massage arm P1 includes an upper arm portion and a lower arm portion arranged in a V-shape. Both arms are equipped with massage wheels, namely an upper massage wheel and a lower massage wheel. In another embodiment, it may only include the upper arm portion and the upper massage wheel. The kneading drive mechanism P2 is used to drive the massage arm P1 to swing in the left and right directions to perform kneading massage. It includes a kneading drive motor P21 and a kneading shaft P22. The kneading drive motor P21 drives the kneading shaft P22 to rotate. The massage arms P1 are connected to the left and right sides of the kneading shaft P22. In this embodiment, the left and right sides of the kneading shaft P22 are inclined. The knocking drive mechanism P3 is used to drive the massage arm P1 to vibrate back and forth and perform knocking massage. It includes a knocking drive motor P31, a knocking shaft P32 and a knocking connector P33. The knocking drive motor P31 drives the knocking shaft P32 to rotate, and the knocking shaft P32 is connected to the massage arm P1 through the knocking connector P33. The kneading drive mechanism P2 and the knocking drive mechanism P3 are common structures and will not be described in detail. Figure 9 In the vertical direction, the kneading drive motor P21 is located between the striking drive motor P31 and the body pressure detection device 5. The body pressure detection device 5 is located between the support frame P0 and the swing seat 4E.

[0029]

Travel drive device

[0030] [Tilt Adjustment Device] The tilt adjustment device 4 includes a tilt drive motor 4A, a tilt shaft 4B, a tilt gear 4C, an arcuate rack 4D, and a swing base 4E. The tilt drive motor 4A and tilt shaft 4B are mounted on the frame 1. The tilt gear 4C is mounted on the tilt shaft 4B and rotates therewith. The arcuate rack 4D is mounted on the swing base 4E and meshes with the tilt gear 4C. The lower side of the swing base 4E is pivotally connected to the frame 1 so that it can swing back and forth. In this embodiment, the lower side of the swing base 4E is rotatably mounted on the lower travel shaft 3B. When the tilt drive motor 4A is in operation, it drives the tilt shaft 4B and tilt gear 4C to rotate. The tilt gear 4C drives the swing base 4E to swing via the arcuate rack 4D. As the swing base 4E swings back and forth, it drives the massage device 2 to swing accordingly, thereby adjusting the massage intensity of the massage device 2. In this embodiment, the support frame P0 and the swing seat 4E of the massage device 2 are both sleeved on the lower travel shaft 3B, and the rotation axis of the massage device 2 and the swing seat 4E coincide with each other. Figure 5 In this embodiment, the swing seat 4E includes a longitudinal extension member M1 provided in the upper and lower parts, and a transverse extension member M2 provided in the front and rear parts. The front side of the transverse extension member M2 is connected to the upper side of the longitudinal extension member M1, the arc-shaped rack 4D is installed on the left and right sides of the transverse extension member M2, and the body pressure detection device 5 is installed between the longitudinal extension member M1 and the massage device 2. The upper side of the longitudinal extension member M1 has a limit member M11, and the rear side of the transverse extension member M2 has a limit member M21. When the limit member M11 swings backward and contacts the forward tilting gear 4C, it is hindered and cannot continue to swing, thereby preventing the swing seat 4E from excessively tilting backward; when the limit member M21 swings forward and contacts the forward tilting shaft 4B, it is hindered and cannot continue to swing, thereby preventing the swing seat 4E from excessively tilting forward. Combined Figure 5 The lateral extension M2 of the pendulum seat 4E has a front magnetic element Q12 and a rear magnetic element Q13. The position detection element Q11 is a Hall effect sensor that works with the front and rear magnetic elements Q12 and Q13. By combining the magnetic element and the position detection element, the massage movement controller can detect the forward and backward swing position of the pendulum seat 4E.

[0031] [Body pressure detection device] The body pressure detection device 5 is used to detect the body pressure acting on the massage device 2. The body pressure detection device 5 is installed between the massage device 2 and the longitudinal extension M1 of the swing seat 4E. The swing seat 4E drives the massage device 2 to swing back and forth through the body pressure detection device 5. Figures 12 to 13 In this embodiment, the body pressure detection device 5 includes a body pressure sensor 5A, a first connecting member 5B, and a second connecting member 5C. The rear side of the body pressure sensor 5A is connected to the first connecting member 5B. The rear side of the first connecting member 5B is pivotally connected to a first pivot rod T1 and connected to the support frame P0 of the massage device 2 via the first pivot rod T1. The second connecting member 5C includes a first shell G1 and a second shell G2, which are joined together. The body pressure sensor 5A is clamped between the first shell G1 and the second shell G2. The front side of the first connecting member 5B passes through the second shell G2 and is connected to the rear side of the body pressure sensor 5A. The second shell G2 is pivotally connected to the second pivot rod T2 and connected to the swing seat 4E via the second pivot rod T2.

[0032] The massage mechanism of the present application, the massage device 2, and the pendulum seat 4E can each rotate about a predetermined axis (in this embodiment, about the lower travel axis 3B), and the two can produce a small relative displacement when the massage device 2 is subjected to body pressure. When the massage mechanism of the present application is used in a massage chair, in the initial state, the massage mechanism is not in operation and the body pressure detection device 5 is not subjected to force.

[0033] Combine Figure 9 and Figure 11When the massage device 2 is massaging the user's back (i.e., the massage device 2 is in the first massage zone and the massage mechanism is in normal operation), the tilt adjustment device 4 is in operation, causing the tilt shaft 4B and tilt gear 4C to rotate. The tilt gear 4C drives the meshed curved rack 4D, the pendulum seat 4E, the body pressure detection device 5, and the massage device 2 to rotate forward, centered around the lower travel axis 3B. When the upper massage wheel of the massage device 2 contacts the user's back, the massage device 2 stops tilting due to the force of the first body pressure F1. The curved rack 4D and the pendulum seat 4E remain stationary due to the action of the tilt gear 4C. As the tilt gear 4C continues to rotate, the first body pressure F1 exerted on the upper massage wheel of the massage device 2 gradually increases. This first body pressure F1 is transmitted to the body pressure detection device 5 via the first pivot rod T1, and the body pressure detection device 5 detects the corresponding first body pressure value F1'. During a back massage, the massage device 2 tilts slightly forward, and the body pressure sensor 5A of the body pressure detection device 5 is subjected to a backward pull. When the tension value detected by the body pressure sensor 5A reaches the set massage intensity value, the control mechanism of the massage movement controls the forward tilt adjustment device 4 to stop its action. When the tension value detected by the body pressure sensor 5A is greater than the set massage intensity value, the control mechanism of the massage movement controls the forward tilt adjustment device 4 to drive the massage device 2 backward until the tension value reaches the set massage intensity value; when the tension value is less than the preset massage intensity value, the control mechanism of the massage movement controls the forward tilt adjustment device 4 to drive the massage device 2 to continue moving forward until the tension value reaches the preset massage intensity value. The action of the forward tilt adjustment device 4 is adjusted by the tension value detected by the body pressure detection device 5 so that the massage device 2 maintains a constant massage intensity for the user (it should be understood that the design requirement of constant massage intensity is met if the tension value reaches the preset massage intensity value within the preset error range).

[0034] Combine Figure 10 and Figure 11 When the massage device 2 moves upward from the user's waist (i.e., the massage device 2 is in the second massage area, and the portion of the body located in this area is concave forward), the massage device 2 is in a forward tilted state with a relatively large amount of tilt (the user's waist is concave relative to the back and buttocks, so the massage device 2 must tilt forward a large amount to contact the user's waist). The massage device 2 presses against the user's waist. At this time, as the massage movement moves upward, the upper portion of the upper massage wheel of the massage device 2 is subjected to a second downwardly directed body pressure F2. This second body pressure F2 is transmitted to the body pressure detection device 5 via the first pivot rod T1. The body pressure detection device 5 detects the corresponding body pressure value F2', and the body pressure sensor 5A of the body pressure detection device 5 is subjected to a forward force. When the body pressure sensor 5A is subjected to the forward pressure, the massage movement's control mechanism controls the forward tilt adjustment device 4 to drive the massage device 2 backward until the forward pressure on the body pressure sensor 5A changes to a backward pulling force, at which point the forward tilt adjustment device 4 stops operating.

[0035] In the massage movement of the present application, the body pressure detection device 5 can detect the forward and reverse forces applied by the user (rearward pulling force and forward pressure, respectively, in the aforementioned embodiments). When the body pressure detection device 5 detects the forward force, the control mechanism maintains the massage force of the massage device 2 constant through the action of the forward tilt adjustment device 4. The body pressure detection device 5 of the massage movement is capable of real-time pressure detection. When the massage device 2 presses against the user's waist and moves upward, the upward movement of the massage device 2 presses against the user, causing discomfort to the human body. At this time, the body pressure detection device 5 detects the reverse force. When the control mechanism detects the reverse force, it controls the forward tilt adjustment device 4 to drive the massage device 2 backward until the force detected by the body pressure detection device 5 becomes the forward force.

[0036] In the massage machine of the present application, the body pressure detection device can assist in adjusting the massage intensity of the massage device, and assist in adjusting the upward movement of the massage movement on the body.

[0037] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
