Description

An additional forward-moving zero-gravity massage chair frame

Technical field:

The utility model relates to an additional forward-moving zero-gravity massage chair frame, especially when the seat is upturned and the backrest is reclined to simulate the state of weightlessness, the seat and the backrest will move forward to reduce the rear space occupied by the backrest.

Background technique:

In existing massage chairs, when the seat is upturned and the backrest is reclined to a certain position, the human body will feel weightless, that is, a zero-gravity state is simulated, and a simple zero-gravity mechanism is easy to realize, which is also the basic structure of most massage chairs; As we all know, the reclining chair with adjustable backrest, when the backrest angle is adjusted, that is, when the backrest is properly leveled, the backrest will tilt backward, and there needs to be enough space at the rear, otherwise it will hit other objects or walls This is especially true for large massage chairs. It is obviously very troublesome to adjust the position of the seat every time you use it. Most of the places of use cannot meet this condition of use at home. How to improve the structure of the existing backrest adjustable seat, when adjusting zero gravity, the mechanism that the backrest can move forward becomes the object of the utility model research.

Invention content:

The purpose of this utility model is to design an additional forward-moving zero-gravity massage chair frame in which the backrest frame and the cushion frame are installed on the sliding frame of the base, the process of backrest reclining is adjusted, and the sliding frame is driven forward through the linkage rod group.

The technical scheme of the utility model is realized in the following way: an additional forward-moving zero-gravity massage chair frame includes a base, a cushion frame, a backrest frame, an electric push rod and a linkage rod group, the cushion frame is installed on the base, and the lower part of the backrest frame It is hinged with both sides of the rear part of the cushion frame. It is characterized in that a sliding frame is movably positioned on the base. The front part of the sliding frame is equipped with ground pulleys, and the two sides of the rear part are respectively equipped with sheaves. The sheaves are set on the tracks on both sides of the base. In the groove, it can not only slide back and forth along the track groove, but also be constrained by the track groove; the rear part of the sliding frame is fixed with a longitudinal pillar, and one end of the electric push rod is hinged at the front; the rear part of the cushion frame is articulated at the upper end of the longitudinal pillar , the front part is hinged on the other end of the electric push rod, and is supported by the electric push rod; the linkage group is composed of upper link, front link and rear link One end of the rod is hinged together, the other end of the upper link is hinged at the front of the cushion frame, the other end of the front link is hinged at the base, and the other end of the rear link is hinged at the sliding frame; The cushion frame, the upper link and the front link are opened around the hinge point, and the rear link pulls the sliding frame to move forward to form a linkage structure.

There is also a guide mechanism between the base and the sliding frame, which includes a slideway in the middle of the base and a slide rail fixed on the slide frame, which is embedded in the slideway by means of the slide rail to form a forward-moving guide and a pair of sliding frames. limit structure.

The track groove on the base is in an upright rectangular structure, and the front and rear ends are the stroke end points of the sheave on the sliding frame, corresponding to the two limit points of the backrest frame for sitting and lying adjustment.

The cushion frame and the backrest frame of the utility model are installed on the sliding frame, the sliding frame can move forward relative to the base, the electric push rod is stretched, and the upturning of the cushion frame and the lying process of the backrest frame are adjusted, and the sliding frame is driven forward by the linkage rod group to realize When zero-gravity is adjusted, the forward movement is added to achieve the purpose of not occupying the rear space during the backrest lying flat; and it is driven by a single electric push rod, which has the characteristics of ingenious structure, reasonable linkage and flexible driving, and is very suitable as a massage chair. shelf.

Detailed ways:

Referring to Figure 1, Figure 2 and Figure 3, the additional forward-moving zero-gravity massage chair frame includes a base 1, a cushion frame 2, a backrest frame 3, an electric push rod 4, and a matching calf frame 5 and linkage rod group 6; The bottom of the back frame 3 is hinged with the both sides of the rear portion of the cushion frame 2, and a sliding frame 7 is movable on the base 1. The front portion of the sliding frame 7 is provided with a pulley 71 on the ground, and both sides of the rear portion are respectively provided with a sheave 72. 72 is erected in the track grooves 11 on both sides of the base 1, which can slide back and forth along the track grooves 11 and is constrained by the track grooves; The travel end point of 72 corresponds to the two limit points of the adjustment of the backrest frame 3 when sitting or lying down. The rear part of the sliding frame 7 is fixed with a longitudinal strut 73 and one end of the front hinged electric push rod 4; Supported by the electric push rod 4, the electric push rod 4 is stretched, so that the cushion frame 2 can be wound around the hinge point of the longitudinal pillar 73 to realize the front part tilting action, and the backrest frame 3 is then tilted backward to realize zero-gravity adjustment.

Described link group 6 is made up of upper link 61, front link 62 and rear link 63, and one end of upper link 61, front link 62 and rear link 63 is movably hinged together, and the other end of upper link 61 One end is hinged on the front of the cushion frame 2, the other end of the front connecting rod 62 is hinged on the base 1, and the other end of the rear connecting rod 63 is hinged on the sliding frame 7; Rod 61 and front link 62 open around the hinge point, and the rear link 63 pulls the sliding frame 7 to move forward to form a linkage structure; since the cushion frame 2 is installed on the sliding frame 7, the cushion frame 2 and the backrest frame 3 together Moving forward along with the slide frame 7, the backrest frame 3 that reduces the reclining adjustment takes up the rear space.

As shown in Fig. 1 and Fig. 2, a guiding mechanism is also provided between the base 1 and the sliding frame 7, and the guiding mechanism includes a slideway 12 in the middle of the base 1 and a sliding rail 74 fixed on the sliding frame 7, by means of the sliding rail 74 embedded In the slideway 12, a forward-moving guide and a position-limiting structure for the sliding frame 7 are formed, that is, to avoid left and right deviation when moving forward, so that the movement is more smooth and coherent.

In addition, the above-mentioned calf frame 5 is driven by an independent electric push rod 4, as shown in Figure 4, one end of the electric push rod 4 is hinged at the rear part of the cushion frame 2, or the rigid triangle between the cushion frame 2 and the backrest frame 3. On the frame 21, the other end is hinged at the middle part of the outreach arm 22. One end of the outreach arm 22 is hinged at the front part of the cushion frame 2, and the other end is equipped with a top wheel 23, which is forwarded by the electric push rod 4 by means of the outreach arm 22. When pushing away, the calf frame 5 is held up, and the calf frame 5 is retracted to fall according to its own weight.
