The transition frame 4 is equipped with a transition rack P3 for the movement of the massage mechanism's traveling gears. The transition rack P3 is located between the seat rack P1 and the backrest rack P2. Figure 5 and Figure 13 In this embodiment, the transition frame 4 includes a rack support 4A, a pressure member 4B, a connecting rod 4C, a first pin 4D, a second pin 4E, a seat frame sliding sleeve 4F, a backrest frame sliding sleeve 4G, and a side mounting plate 4H.

[0034] The rack support 4A is generally arc-shaped, having an upper wall, a lower wall, and a side wall located between the upper and lower walls. The transition rack P3 is mounted on the rack support 4A (mounted on the lower wall), and the pressure-applying component 4B is mounted on the rack support 4A (mounted on the upper wall). The pressure-applying component 4B applies pressure to the traveling wheels of the massage mechanism, preventing the traveling rollers from bouncing at the transition frame 4 position. A connecting rod 4C is positioned along the left-right direction X on the outside of the rack support 4A, and the connecting rod 4C and the side mounting plate 4H are spaced apart along the left-right direction X. A pivot rod T is located between the connecting rod 4C and the side mounting plate 4H. First pins 4D and second pins 4E extend along the left-right direction X, connecting the connecting rod 4C, the seat frame sliding sleeve 4F, and the backrest frame sliding sleeve 4G to the side mounting plate 4H. Figure 7 The first pin 4D passes through the first waist hole S1, and the seat frame sliding sleeve 4F is fitted onto the first pin 4D. The seat frame sliding sleeve 4F is in sliding engagement with the first waist hole S1, so that the first pin 4D rotates and slides with the first waist hole S1 of the seat frame 2 through the seat frame sliding sleeve 4F, thus allowing the transition frame 4 to rotate and slide with the seat frame 2. The second pin 4E passes through the second waist hole S2, and the backrest frame sliding sleeve 4G is fitted onto the second pin 4E. The backrest frame sliding sleeve 4G is in sliding engagement with the second waist hole S2, so that the second pin 4E rotates and slides with the second waist hole S2 of the backrest frame 3 through the backrest frame sliding sleeve 4G, thus allowing the transition frame 4 to rotate and slide with the backrest frame 3. Compared to a round hole, this application uses a design with a first waist hole S1 and a second waist hole S2, which facilitates the assembly of the transition frame 4 with the seat frame 2 and the backrest frame 3.

[0035] [Drive Mechanism] The drive mechanism 5 is used to drive the seat frame 2 and backrest frame 3 to move relative to the base frame 1.

The first positioning component 7A includes a first positioning rack M1 and a first positioning gear N1. The first positioning rack M1 is mounted on the seat frame 2, and the first positioning gear N1 is sleeved on the first pin 4D and clamped between the connecting rod 4C and the side mounting plate 4H. The first positioning rack M1 is located outside the seat rack P1 and the transition rack P3 in the left-right direction X and corresponds to their positions. The first positioning gear N1 is disposed on the transition frame 4 and meshes with the first positioning rack M1.

[0039] The second positioning component 7B includes a second positioning rack M2 and a second positioning gear N2. The second positioning gear N2 is sleeved on the second pin 4E and clamped between the connecting rod 4C and the side mounting plate 4H. The second positioning rack M2 is mounted on the backrest frame 3. The second positioning rack M2 is located outside the backrest rack P2 and the transition rack P3 in the left-right direction X and corresponds to their positions. The second positioning gear N2 is disposed on the transition frame 4 and meshes with the second positioning rack M2. The parameters of the first positioning rack M1 correspond to the parameters of the seat rack P1 and the transition rack P3. The parameters of the second positioning rack M2 correspond to the parameters of the backrest rack P2 and the transition rack P3. The parameters of the first positioning gear N1 and the second positioning gear N2 correspond to the parameters of the walking gear of the massage mechanism.

[0040] [Limiting Mechanism] The limiting mechanism 8 is used to prevent the running wheels of the massage mechanism from bouncing at the junction of the seat frame 2 and the transition frame 4, and at the junction of the backrest frame 3 and the transition frame 4. Specifically, in this embodiment, the limiting mechanism 8 includes a seat-side pressure strip 8A and a back-side pressure strip 8B. The seat-side pressure strip 8A is disposed on the seat frame 2 to prevent the running wheels of the massage mechanism from bouncing at the junction of the seat frame 2 and the transition frame 4. The back-side pressure strip 8B is disposed on the backrest frame 3 to prevent the running wheels of the massage mechanism from bouncing at the junction of the backrest frame 3 and the transition frame 4.

Electrical Control Box

[0042] [Movable Shielding Component] The movable shielding component 10 is mounted on the base frame 1 and is located between the lower side of the rear cover G and the front side of the electrical control box 9. The movable shielding component 10 slides with the base frame 1, and an elastic element 11 is provided between it and the base frame 1. Figure 4 When the back cover G tilts backward relative to the base frame 1 as the backrest frame 3 tilts backward, it pushes the movable blocking assembly 10 to slide relative to the base frame 1, causing the elastic element 11 to elastically deform. Correspondingly, when the back cover G is lifted upward relative to the base frame 1 as the backrest frame 3 lifts upward, the elastic element 11 returns to its original position, causing the blocking assembly 10 to return to its original position. The elastic element 11 is a telescopic spring, one end of which is hooked to the hook end 1E of the base frame 1.

[0043] Combination Figures 9 to 11In this embodiment, the movable shielding assembly 10 includes a sliding cover 10A, an abutment 10B, a sliding joint 10C, a pin 10D, and a connector 10E.

The other end of the elastic member 11 is hooked to the connector 10E. The abutment 10B is mounted on the upper side of the sliding cover 10A and is located between the rear cover G and the sliding cover 10A. The rear cover G pushes the movable shielding assembly 10 to move by applying pressure to the abutment 10B. In this embodiment, both the abutment 10B and the sliding joint 10C are rollers. The sliding joint 10C, the pin 10D, and the connector 10E cooperate to form a sliding structure, through which the sliding cover 10A slides with the base frame 1. In this embodiment, two sliding structures are provided on the left and right sides of the sliding cover 10A. exist Figures 9 to 11 In the embodiment, the elastic member 11 is used to elastically extend and then reset to drive the sliding cover 10A to reset. However, it should be understood that the position of the elastic member 11 can also be adjusted so that the elastic member 11 elastically contracts when the back cover G tilts backward relative to the base frame 1 along with the backrest frame 3. Then the elastic member 11 can be used to reset to drive the sliding cover 10A to reset.

[0044] The above is a detailed description of the massage chair according to the first embodiment. The side frame 6 is rotatably engaged with the backrest frame 3, and simultaneously slidably engaged with the base frame 1, seat frame 2, and backrest frame 3. This allows the user's armrests, supported on the side frame 6, to move with the side frame. When an armrest massage structure is installed on the side frame 6, the armrest massage structure can massage the user's hands in a normal orientation, helping to ensure the massage effect. It should be understood that this application may also have other modified design embodiments.

[0045] [Second Embodiment] Unlike the first embodiment, the side frame 6 is slidably engaged with the base frame 1, the seat frame 2, and the backrest frame 3. In the second embodiment, only one or two of the base frame sliding joint 6B, the seat frame sliding joint 6C, and the backrest frame sliding joint 6D may be provided, and the side frame 6 is slidably engaged with one or two of the base frame 1, the seat frame 2, and the backrest frame 3.

[0046] [Third Embodiment] Based on the first embodiment, it can be adjusted to have only a first waist hole or a second waist hole.

[0047] [Fourth Embodiment] Based on the first embodiment, it can be adjusted to have only the first positioning component or the second positioning component.

[0048] [Fifth Embodiment] Based on the first embodiment, the base frame 1 can be adjusted to have only a seat frame guide rail 1A, and the seat frame guide rail 1A can be adjusted to be an arc-shaped guide rail. The seat frame 2 is still supported on the seat frame guide rail 1A of the base frame 1. An additional drive mechanism is provided between the seat frame 2 and the backrest frame 3 to drive the backrest frame 3 to move relative to the seat frame 2.

[0049] [Other] It should be understood that, in the first embodiment, the design concept of the movable shielding component 10 and the elastic element 11 can be applied to other massage chairs where the backrest frame 3 and the back cover G are movable relative to the base frame 1. For example, it can be applied to massage chairs where the seat frame 2 and the backrest frame 3 are integrated, and the seat frame 2 and the backrest frame 3 are installed on the base frame 1 as a whole and can move relative to the base frame 1.

[0050] 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.
