Description

Backrest support structure for massage chair

Technical Field

The utility model belongs to the technical field of massage armchair technique and specifically relates to a back bearing structure for massage armchair.

Background

The common riding feeling of the massage armchair on the market at present is poor because the back part of the massage armchair falls into the hollow area of the backrest of the massage armchair. The backrest leaves an unsupported, empty area for the massage device to move up and down. When the massage armchair is used by a customer, the massage armchair has two states, namely sitting and massage. When a client takes the massage, the massage device moves up and down to support the human body at different positions. When a client sits on the chair without massage, the inner hollow area of the backrest is only the surface sleeve to hold the human body, the whole rear part of the human body sinks, and the sitting feeling is poor.

Disclosure of Invention

The utility model overcomes prior art's is not enough, provides a back bearing structure for massage armchair, and it is when the human body does not massage, can effectually support the human body, holds up whole back, alleviates the crooked oppression of vertebra and waist, convenient activity, the comfort level that great improvement was taken.

In order to realize the purpose, the utility model discloses a technical scheme is: a backrest supporting structure for a massage chair comprises a backrest frame, wherein a cavity for an external massage device to move up and down is formed in the backrest frame, a supporting plate is arranged at the cavity of the backrest frame in a lifting mode, and the backrest supporting structure further comprises a driving assembly for driving the supporting plate to lift; when the supporting plate is lowered, the external massage device can move up and down at the cavity.

By adopting the scheme, when the external massage device moves up and down to massage, the driving component drives the supporting plate to descend, so that a space for the external massage device to move up and down is reserved; when the external massage device moves downwards and is not used for massage, the driving assembly drives the supporting plate to rise, the front surface of the supporting plate can be used for supporting a human body, the whole back part is supported, bending and pressing of the spine and the waist are relieved, the movement is convenient, the riding comfort degree is greatly improved, and the supporting plate can be stopped at any position according to personal requirements in the lifting process.

The utility model discloses a further setting is: the backup pad passes through the connecting rod and is connected with the back frame, and the articulated cooperation of first articulated shaft and backup pad is passed through to the one end of connecting rod, and the other end of connecting rod passes through the articulated cooperation of second articulated shaft and back frame, and when the connecting rod uses the second articulated shaft to overturn as articulated fulcrum, can drive the backup pad and go up and down.

Through adopting above-mentioned scheme, the length of connecting rod has decided the biggest rise height of backup pad, drives the backup pad through the connecting rod is indirect and goes up and down, simple structure, and the transmission is stable.

The utility model discloses a further setting is: the driving assembly comprises an electric push rod, a body of the electric push rod is hinged and matched with the backrest frame, and the end part of a telescopic rod of the electric push rod is hinged and matched with the supporting plate.

By adopting the scheme, when the telescopic rod of the electric push rod extends, the supporting plate descends; when the telescopic rod of the electric push rod retracts, the supporting plate rises, the structure is simple, and the control is convenient.

The utility model discloses a further setting is: the connecting rods are four, four corners of the supporting plate are respectively provided with a hinged seat matched with the corresponding connecting rod, the backrest frame extends downwards to form a support, the upper end of each connecting rod is hinged and matched with the corresponding hinged seat, and the lower end of each connecting rod is hinged and matched with the support.

By adopting the scheme, the four connecting rods are uniformly distributed at the four corners of the supporting plate, the stress of the supporting plate is more uniform, and the supporting plate is more stable and is not easy to move when supporting a human body.

The present invention will be further described with reference to the accompanying drawings.
