DETAILED DESCRIPTION

The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

As shown in Figure 1-4,

A calf-linked leisure massage chair, comprising

Base 1;

A connecting seat 2 is connected to the base 1 in a horizontally rotatable manner;

The backrest bracket 3 is slidably mounted on the connecting seat 2;

A driving component 4 is mounted on the connecting seat 2 and connected to the chair support 3 to drive the chair support 3 to slide back and forth on the connecting seat 2;

A calf support 5, which is reversibly connected to the chair support 3;

The connecting rod assembly 6 is connected between the calf support member 5 and the connecting seat 2 and is linked with the backrest bracket 3. As the backrest bracket 3 slides back and forth on the connecting seat 2, the calf support member 5 is driven to be lifted or retracted.

The conventional calf support 5 is driven by an electric push rod 42 or a hydraulic push rod 42, or the calf support 5 is lifted or retracted by the extension of a rack. This existing solution has the problems of complex structure, heavy weight, and easy exposure of parts. Especially as a leisure massage chair, the seat part can generally rotate horizontally, and the seat part and the base 1 are connected by a rotating shaft. The bottom space is small and cannot accommodate a structure with a large volume. The final effect of the product is easily affected by weight and aesthetic issues.

This solution links the calf support 5 and the backrest bracket 3 through the connecting rod assembly 6. The connecting rod assembly 6 has a simple structure and is easy to install. It only needs to be hinged through multiple connecting rods, and the calf support 5 can be lifted or retracted by rotating, folding and unfolding. It occupies a small volume and is light in weight. It is not easy to affect the balance of the backrest bracket 3 and the stress state of the base 1 and the connecting seat 2. In addition, the small volume can better hide the components and the aesthetic effect is better. The backrest bracket 3 slides on the connecting seat 2, mainly used to produce a tilting posture, so that the user is more in a lying position and increases comfort. Moreover, sliding and tilting will produce displacement, which is used to cooperate with the connecting rod assembly 6 to drive the calf support 5 to lift or retract. The linkage method is simple, the operation is stable, and the maintenance and installation are also convenient. Moreover, only the driving component 4 on the backrest bracket 3 needs to be driven to produce linkage, so that the calf support 5 can produce the action of lifting or retracting. There is no need to add additional driving components to the calf support 5, which can also have the effect of reducing costs.

Specifically, as shown in Figure 2, the connecting rod assembly 6 includes a first connecting member 61, a second connecting member 62, and a third connecting member 63. The first connecting member 61 is hinged to the calf support member 5 and is used to lift the calf support member 5; the second connecting member 62 cooperates with the connecting seat 2 to support the first connecting member 61, and the first connecting member 61 and the second connecting member 62 are hinged to each other; the third connecting member 63 is hinged to the backrest bracket 3, and is hinged to the second connecting member 62 or the node where the first connecting member 61 and the second connecting member 62 are hinged; when the backrest bracket 3 is reset, the third connecting member 63 is reset with the backrest bracket 3, and brings the first connecting member 61 and the second connecting member 62 to retract the calf support 5; when the backrest bracket 3 slides and tilts, the third connecting member 63 moves with the backrest bracket 3, and brings the first connecting member 61 and the second connecting member 62 to unfold and lift the calf support 5.

The first connecting member 61 is used to support the calf component, the second connecting member 62 is used to cooperate with the connecting seat 2 to provide support through the connecting seat 2, and the third connecting member 63 can move with the chair support 3, and the calf support member 4 is pushed to lift by lifting the second connecting member 62. In this way, the calf support member 4 and the chair support 3 form a linkage, simplifying the structure of the massage chair and reducing the weight.

In the specific movement process, after the backrest bracket 3 is in the initial state and starts the lying down action, the backrest bracket 3 slides, and at this time, the position where the third connecting member 63 is hinged to the backrest bracket 3 moves with the backrest bracket 3 (at this time, the third connecting member 63 rotates counterclockwise relative to the backrest bracket 3), and lifts the second connecting member 62 (at this time, the second connecting member 62 rotates clockwise relative to the connecting seat 2), allowing the second connecting member 62 and the first connecting member 61 to open (at this time, the first connecting member 61 rotates counterclockwise relative to the second connecting member 62), and lifts the calf support member 4, thereby generating a linkage effect. At this time, the calf support member 4 can be lifted with the state switching of the backrest bracket 3 without an additional driving source. When the backrest bracket 3 is reset, the backrest bracket 3 moves in the opposite direction, and at this time, the position where the third connecting member 63 is hinged to the backrest bracket 3 moves with the backrest bracket 3, and retracts the second connecting member 62, the first connecting member 61 and the second connecting member 62 begin to fold, and retract the calf support member 4.

In further configuration, in order to further reduce the occupied space and exposed parts and improve the aesthetics, the following methods can be selected for implementation:

1 and 3, the connecting rod assembly 6 also includes a fourth connecting member 64 and a fifth connecting member 65, and the second connecting member 62 forms a movable fulcrum through the combination of the fourth connecting member 64 and the fifth connecting member 65; the fourth connecting member 64 is hinged to the second connecting member 62 and to the connecting seat 2; the fifth connecting member 65 is hinged to the backrest bracket 3, and is hinged to the node where the second connecting member 62 and the fourth connecting member 64 are hinged or to the fourth connecting member 64; the second connecting member 62 supports the first connecting member 61 through the combination of the fourth connecting member 64 and the fifth connecting member 65; when the backrest bracket 3 slides and resets, the fifth connecting member 65 moves with the backrest bracket 3, and folds the second connecting member 62 and the fourth connecting member 64; when the backrest bracket 3 slides and tilts, the fifth connecting member 65 moves with the backrest bracket 3, and unfolds the second connecting member 62 and the fourth connecting member 64.

The difference from the above scheme is that in the above scheme, the second connecting member 62 and the connecting seat 2 can be directly hinged, and the hinge point is used as a fixed fulcrum and will not move with the movement of the backrest bracket 3, and is used as a hinge support point to support the second connecting member 62. In this scheme, the second connecting member 62 is hinged with the fourth connecting member 64, and the fourth connecting member 64 is hinged with the connecting seat 2. The fourth connecting member 64 and the fifth connecting member 65 are used to support the second connecting member 62, and the supporting function of the connecting seat 2 is transmitted to the second connecting member 62. The second connecting member 62 and the fourth connecting member 64 can form a folded state as the state of the backrest bracket 3 changes, thereby reducing the occupied space, and can be better hidden after folding, reducing the exposed part of the connecting rod assembly 6. In addition, this folding scheme can also increase the swing stroke of the calf support member 4, increase the adjustment range of the calf posture, and allow the calf to be lifted higher. The human body posture can be more inclined to a lying state, allowing the user to be more relaxed during massage.

The fifth connecting member 65 moves with the movement of the chair support 3, and then folds or unfolds the second connecting member 62 and the fourth connecting member 64. The fourth connecting member 64 and the fifth connecting member 65 cooperate with each other to reduce the length requirement of the second connecting member 62, so the hiding effect is better.

During operation, when the backrest bracket 3 slides and tilts, referring to the changes in FIGS. 1 and 3 , the fifth connecting member 65 rotates counterclockwise relative to the backrest bracket 3, the fourth connecting member 64 rotates counterclockwise relative to the connecting seat 2, the third connecting member 63 rotates clockwise relative to the backrest bracket 3, the second connecting member 62 rotates clockwise relative to the fourth connecting member 64, and the first connecting member 61 rotates counterclockwise relative to the second connecting member 62. After this movement process, the folded connecting rod assembly 6 can be unfolded, and the second connecting member 62 can be supported by the fourth connecting member 64 and the fifth connecting member 65. In the case of a larger swinging formation of the calf support member 4, the volume of the connecting rod assembly 6 can be further reduced and the exposure can be reduced.

The connecting rod assembly 6 is constituted by the first, second, third, fourth and fifth connecting parts, and can cooperate with the chair bracket 3 to produce a linkage effect, so that the calf support member 5 is lifted when the chair bracket 3 slides and tilts. The simple structure can achieve the effect of convenient installation and maintenance, and has less exposed parts in appearance, good aesthetic effect, small occupied volume, reduced weight problem, easier to maintain the center of gravity, relieve the pressure on the base 1 and the shaft on the base 1, and help to extend the service life.

More preferably, the driving component 4 includes a driving seat 41 hinged on the connecting seat 2 and a push rod 42 telescopically arranged on the driving seat 41, the push rod 42 is hinged to the chair bracket 3, and the driving seat 41 is driven by electric, hydraulic or pneumatic pressure to telescope the push rod 42.

Of course, the driving seat 41 can also be hinged on the chair bracket 3, and the push rod 42 can be hinged on the connecting seat 2, which is equivalent to replacing the positions of the driving seat 41 and the push rod 42, but it does not affect the driving function.

This solution only needs one driving component 4 to drive the chair support 3 to slide, and uses the connecting seat 2 as a support. When rotating horizontally, it can rotate with the connecting seat 2 without affecting the sliding, tilting and resetting functions of the chair support 3.

For better coordination, as shown in FIG4 , a plurality of pulleys 21 are provided on both sides of the connecting seat 2, and an arc-shaped slide rail 31 is provided at the position of the chair bracket 3 corresponding to the pulley 21. The chair bracket 3 is installed on the connecting seat 2 through the arc-shaped slide rail 31 in coordination with the pulley 21. The slide rail 31 and the pulley 21 cooperate to guide the chair bracket 3 to slide on the connecting seat 2 along the arc-shaped track of the slide rail 31.

The arc-shaped slide rail 31 can produce a tilting effect during the sliding process, and can reduce the change of the center of gravity position to maintain better stability. In addition, as the sliding causes the legs to move upward, the third connecting member 63 and the fourth connecting member 64 can also produce an upward movement, which helps the first connecting member 61 and the second connecting member 62 to unfold. The pulley 21 cooperates with the slide rail 31 to make the sliding smoother.

In order to make the cooperation state between the slide rail 31 and the pulley 21 more stable, a groove 311 is provided on the side of the slide rail 31, and the pulley 21 enters the groove 311 from the side of the slide rail 31 and slides in the groove 311. The groove 311 cooperates with the pulley 21, and the upper groove wall of the groove 311 cooperates with the pulley 21.

In further optimization, the groove 311 is provided with ribs 312 on both sides near the opening, and the pulley 21 is restricted from sliding in the groove 311 by the ribs 312. The ribs 312 can prevent the pulley 21 from falling out, and the safety is better.

The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
