Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

With reference to fig. 1 to 7, an embodiment of the present invention provides a massage chair, which includes a base 1, a chair frame 2 and a push rod 3, wherein the chair frame 2 is slidably disposed on the base 1, the push rod 3 includes a guide 31 and a slider 32, the slider 32 is reciprocally slidably disposed on the guide 31, one end of the guide 31 is hinged to the base 1, and the slider 32 is hinged to the chair frame 2;

as shown in fig. 1, 6 and 7, a guide rail 11 is disposed on the base 1, a roller 21 is disposed on the chair frame 2, the roller 21 is rollably disposed in the guide rail 11, specifically, swing rods 22 are disposed on both sides of the chair frame 2, and the roller 21 is mounted on the swing rod 22 through a pin shaft, so that the whole chair frame 2 moves in the guide rail 11 under the rolling of the roller 21; the guide rail 11 comprises a lower sliding section 111, a horizontal section 112 and an upper lifting section 113, wherein a first end of the lower sliding section 111 is higher than a second end of the lower sliding section 111, the second end of the lower sliding section 111 is connected with a first end of the horizontal section 112, a second end of the upper lifting section 113 is higher than a first end of the upper lifting section 113, a first end of the upper lifting section 113 is connected with a second end of the horizontal section 112, and a second end of the upper lifting section 113 is higher than the first end of the lower sliding section 111;

when the sliding block 32 slides along the guide member 31 from the lower sliding section 111 to the upper sliding section 113, the sliding block 32 pushes the chair frame 2 to move along the lower sliding section 111, the horizontal section 112, and the upper sliding section 113, so that the chair frame 2 is changed from the sitting posture state to the zero gravity state.

In the embodiment of the utility model, realize the regulation of chair frame through both sides single guide rail, can let the massage armchair reach zero gravity and the effect that zero leaned on the wall.

As shown in fig. 7, specifically, the track 11 on the base 1 is divided into three sections on the track, the first section lower sliding section 111 can increase the stability of the chair frame 2 during initial movement, the second section horizontal section 112 has enough stroke for the forward movement of the chair frame 2, so as to realize a completely zero wall leaning, and the third section upper lifting section 113 allows the chair frame 2 to have a back-falling movement, so as to allow the chair frame 2 to realize a zero gravity posture. Wherein, first section gliding section 111 is the arc section, and the inclination angle scope relative this horizontal segment is 3-10 degrees, just so can be under gravity and push rod 3's pulling force for the initial effort of chair frame 2 preceding slip a needs, and in order to make chair frame 2 can not rock, so inclination can not be less than 3 degrees, simultaneously, inclination also can not be greater than 10, chair frame 2 can interfere with the wall body when falling back more than 10, loses the effect of totally zero leaning on the wall. Compare in current guide rail and do not provide initial effort when the chair frame is preceding smooth for increased the pulling force of push rod, the life of push rod also reduces, and this embodiment is owing to have initial effort, make full use of the influence of gravity, reduced the pulling force of push rod, improved the life of push rod.

The movement process of the massage chair for realizing the complete zero wall leaning action can be divided into the back leaning action and the forward movement action, and the complete zero wall leaning action is realized through the matching of the two actions. The embodiment of the present invention provides an implementation of the back-falling action: when the sitting posture of the massage chair reaches the zero gravity posture, the back of the massage chair is required to be inverted by 20-35 degrees, the angle of the first section lower sliding section 111 needs to be set to meet 3-10 degrees, so the angle of the third section upper lifting section 113 is adjusted according to the first section lower sliding section 111 and the set angle, in the embodiment, the range of the inclination angle between the third section upper lifting section and the horizontal section is set to be 17-25 degrees, and the total change value of the total angle is required to meet 20-35 degrees. And (3) realizing the forward movement action: the horizontal distance of the first section of the lower sliding section 111 is defined according to the length of the backrest of the chair frame 2 and the initial angle, which is the difference of the cosine value of the angle of the front backrest and the rear backrest, the distance of the proposal satisfies 42mm-134mm, meanwhile, in order to make the chair frame 2 have zero wall-leaning effect, the length of the second section of the horizontal section 112 should be close to the distance between the front idler wheel 21 and the rear idler wheel 21 on the chair frame 2, and the total horizontal distance of the second section of the horizontal section 112 and the third section of the upper lifting section 113 should be 400mm-540 mm. The implementation of the back-falling action: since the rising section 113 is inclined with respect to the horizontal section 112, the chair frame is adjusted to the inverted back state at the rising section 113 where the chair frame is pushed. It should be noted that the length of the horizontal segment 112 is set so that the minimum value of any wall surface at the back of the chair frame away from the back of the chair frame before and after the back of the chair frame is unchanged. Specifically, fig. 3 is a schematic view of an initial state of the massage chair, fig. 4 is a schematic view of a forward movement state of the massage chair, fig. 5 is a schematic view of a back-falling state of the massage chair,

further, in one example, the chair frame 2 is provided with a massage movement (not shown) for massaging a human body.

That is to say, the embodiment of the utility model provides a realize the regulation of chair frame through both sides single guide rail, under the prerequisite that realizes zero gravity and complete zero and lean on the wall for massage armchair chair frame structure is simpler, and the motion is more stable, and can reach and improve processing technology, reduce cost's effect.
