The components of the embodiments of this utility model described and shown in the accompanying drawings can be arranged and designed in various different configurations. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0018] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other.

[0019] Combination Figure 1 In one embodiment, the massage chair K of this application includes a massage mechanism and a flexible support bar Q. The illustrations only show a portion of the massage chair's structure. The massage chair K has a mechanism travel space K1, in which the massage mechanism is adapted to be installed and controlled to travel along a predetermined path. In this embodiment, the predetermined path extends generally in the vertical direction, allowing the massage mechanism to move primarily between the user's waist and back. In this embodiment, the flexible support bar Q is a generally flat, elastic, telescopic bar that extends along the aforementioned predetermined path. The flexible support bar Q assists in supporting the user. In this embodiment, the flexible support bar Q is positioned approximately in the middle of the mechanism travel space K1 in the horizontal direction. At least one of the upper and lower sides of the flexible support bar Q can be designed to be detachably connected to the massage chair's body. The specific structure of the massage mechanism will be further described below with reference to the illustrations.

[0020] Combination Figures 2 to 11 In one embodiment, the massage mechanism of this application includes a mechanism frame 1, a massage mechanism 2, a walking drive mechanism 3, a strong / weak drive mechanism 4, a kneading drive mechanism 5, a tapping drive mechanism 6, and a support bar mating member P. The control mechanism of the massage mechanism is omitted in the figure; the control mechanism is, for example, mounted on the mechanism frame 1.

[0021] [Mechanism Frame] The mechanism frame 1 is roughly square in shape. The massage mechanism 2, walking drive mechanism 3, strong and weak drive mechanism 4, kneading drive mechanism 5, and tapping drive mechanism 6 are mounted on the mechanism frame 1. Figure 5 The movement frame 1 has two longitudinal supports 1A spaced apart on the left and right, an upper support 1B connecting the upper side of the two longitudinal supports 1A, a lower support 1C connecting the lower side of the two longitudinal supports 1A, a swing seat pivot 1D located on the lower support 1C, and a strong and weak shaft mounting seat 1E located on the upper support 1B.

[0022] [Massage Mechanism] The massage mechanism includes two massage mechanisms 2, spaced apart from each other. In this embodiment, the massage mechanism 2 includes an upper arm portion and a lower arm portion that are roughly distributed in a V-shape, and each arm portion is equipped with a massage roller, namely an upper massage roller and a lower massage roller. In another embodiment, it may only include an upper arm portion and an upper massage roller.

[0023] [Walking Drive Mechanism] The walking drive mechanism 3 is mounted on the core frame 1. It includes a walking drive motor 3A, a lower walking shaft 3B, and a strong / weak shaft 4B that also serves as an upper walking shaft. The walking drive motor 3A is mounted on the core frame 1 and drives the lower walking shaft 3B to rotate. Walking gears (not shown) are provided on the left and right sides of the lower walking shaft 3B. These gears can mesh with the rack and pinion guide rail (not shown) on the massage chair, allowing the massage mechanism to move along the rack and pinion guide rail. The rotation of the lower walking shaft 3B drives the walking gears to rotate. Lower walking rollers can also be provided on the left and right sides of the lower walking shaft 3B, located outside the walking gears. The rotation of the lower walking shaft drives the lower walking rollers to rotate. The strong / weak shaft 4B, which also serves as an upper walking shaft, is connected to both sides by upper walking rollers (not shown). The upper walking rollers and the strong / weak shaft 4B can rotate relative to each other. The strong / weak shaft 4B also serves as an upper walking shaft, making the overall structure of the massage mechanism more compact.

[0024]

Strong and Weak Drive Mechanism

[0025] A strong / weak drive motor 4A and a strong / weak shaft 4B are mounted on the mechanism frame 1. The strong / weak shaft 4B passes through the strong / weak shaft mounting seat 1E. A strong / weak gear 4C is sleeved on the strong / weak shaft 4B and rotates accordingly. An arc-shaped rack 4D is mounted on the swing seat 4E and meshes with the strong / weak gear 4C. The lower side of the swing seat 4E is pivotally connected to the swing seat pivot member 1D of the mechanism frame 1, which can swing back and forth (in another embodiment, the lower side of the swing seat 4E can be adjusted to be rotatably sleeved on the lower travel shaft 3B). When the strong / weak drive motor 4A is working, it drives the strong / weak shaft 4B and the strong / weak gear 4C to rotate. The strong / weak gear 4C drives the swing seat 4E to swing through the arc-shaped rack 4D. When the swing seat 4E swings back and forth under the control of the strong / weak gear 4C, it drives the massage mechanism 2, the kneading drive mechanism 5, and the tapping drive mechanism 6 to swing accordingly, thereby adjusting the massage intensity of the massage mechanism 2. Because the pivot 1D of the swing seat is located in front of the lower traveling shaft 3B, and the rotation center of the swing seat 4E is located in front of the lower traveling shaft 3B, in this embodiment, the height of the pivot 1D of the swing seat in the vertical direction is lower than that of the lower traveling shaft 3B. This method makes the distance between the upper side of the swing seat 4E and the upper support 1B larger, ensuring that there is more space between the upper side of the swing seat 4E and the upper support 1B for configuring the strong and weak shafts 4B, the strong and weak gears 4C, and the arc rack 4D.

[0026] In this embodiment, the pendulum base 4E includes two pendulum disks M1 spaced apart from each other and an upper connector M2 engaged with the upper side of the two pendulum disks M1. An arc-shaped rack 4D is provided on the upper side of the two pendulum disks M1. The lower side of the pendulum disks M1 is rotatably mounted on the pendulum base pivot connector 1D.

[0027] [Kneading Drive Mechanism] The kneading drive mechanism 5 is mounted on the swing base 4E and is used to drive the two massage mechanisms 2 to swing in the left and right direction for kneading massage. In this embodiment, the kneading drive mechanism 5 includes a kneading drive motor 5A, a kneading shaft 5B, and an eccentric hub 5C. The kneading drive motor 5A and the kneading shaft 5B are mounted on the swing base 4E, and the kneading drive motor 5A drives the kneading shaft 5B to rotate. The eccentric hub 5C is mounted on the kneading shaft 5B, and the two massage mechanisms 2 are sleeved on the eccentric hub 5C. When the kneading shaft 5B rotates, it drives the two massage mechanisms 2 to swing in the left and right direction through the eccentric hub 5C. The kneading drive mechanism is a common structure and will not be described in detail.

[0028] [Percussion Drive Mechanism] The percussion drive mechanism 6 drives the two massage mechanisms 2 to reciprocate and vibrate, performing percussion massage. It includes a percussion drive motor 6A, a percussion shaft 6B, a percussion connector 6C, and a transmission component 6D. The percussion drive motor 6A is connected to the percussion shaft 6B through the transmission component 6D to drive the percussion shaft 6B to rotate. In this embodiment, the transmission component 6D is a pulley structure. The percussion shaft 6B is connected to the massage mechanism 2 through the percussion connector 6C. The percussion drive mechanism 6 is a common structure and will not be described in detail.

[0029] [Supporting elements] combined Figure 1 and Figure 2 The support bar mating part P can move along the set path of the massage mechanism ( Figure 1 During the vertical movement, the flexible support bar Q is restricted from swaying left and right relative to the set path. In this embodiment, the support bar fitting P is installed on the swing seat 4E (specifically, located on the front side of the swing seat 4E) and is positioned between the two massage mechanisms 2 in the left-right direction. Because the support bar fitting P is installed on the swing seat 4E, when the swing seat 4E swings back and forth, it synchronously drives the support bar fitting P to move accordingly.

[0030] Combination Figure 10 and Figure 11 The support bar mating part P has an upper connecting part joint P1, a swing plate joint P2, a wire through hole P3, a mating part P4, and an arc-shaped cover part P5. The upper connecting part joint P1 is used to engage with the upper connecting part M2, and the two can be joined by fastening screws. The swing plate joint P2 is used to engage with the swing plate M1, and the two can be joined by fastening screws. The wire through hole P3 is used for the passage of electrical connection wires of the massage mechanism. For example, the massage roller of the massage mechanism 2 may have a heating element, and the electrical connection wire of the heating element passes through the wire through hole P3 and is electrically connected to the control mechanism. The mating part P4 is used to mate with the flexible support bar Q. In this embodiment, the mating part P4 is located above the wire through hole P3, and it is a through hole adapted to the width of the flexible support bar Q. There are two mating parts P4, spaced apart vertically. An arc-shaped cover P5 is positioned between the two massage mechanisms 2 in a left-right direction. The arc-shaped cover P5 arches forward to form a space on its rear side for the massage mechanism 2 to swing left and right. The mating part P4 is located on the arc-shaped cover P5. In this embodiment, the arc-shaped cover P5 has a guide slope P51 that guides the flexible support bar Q to extend to the mating part P4 (a through hole in this embodiment). The guide slope P51 helps to reduce the frictional resistance between the support bar mating part P and the flexible support bar Q when they move relative to each other.

[0031] The above is a detailed description of a massage chair and massage mechanism according to an embodiment of this application. However, it should be understood that the specific structure and position of the support bar fitting P of this application are not limited to the aforementioned embodiment. In another embodiment, the support bar fitting P is, for example, adjusted to be a generally U-shaped structure protruding from the front surface of the arc-shaped cover P5, and the generally U-shaped structure may have a notch for the flexible support bar Q to pass through.

[0032] When the massage mechanism of this application is installed in the movement space K1 of the massage chair, it can cooperate with the flexible support bar Q through the support bar mating part P to restrict the left and right swing of the flexible support bar Q relative to the set path, so that the flexible support bar Q can support the user more stably.

[0033] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
