Electric lumbodorsal region massage device

Abstract

The invention provides an electric lumbodorsal region massage device (200). The electric lumbodorsal region massage device (200) comprises a lumbodorsal region motor (201), a turbine case (202) and back opening arms (203). The back opening arms are driven to swing by the lumbodorsal region motor through the turbine case, long open holes are formed in bottoms of the back opening arms, the long openholes and a fixed crossbeam on a backrest bracket are in sliding connection through locating pins in the long open holes, so that the back opening arms can form scissors-opening-closing-similar sliding motion mode under the driving of the lumbodorsal region motor and locating of the locating pins in the long open holes, and opening-closing massage is achieved. According to the electric lumbodorsal region massage device, through a unique design that a seesaw-type massage head is of a falcate hook plate, the electric lumbodorsal region massage device is simpler in structure and convenient in assembly; through luffing of the back opening arms, the seesaw-type massage head can be driven to warp up back and forth sequentially, so that the effect of 3D massaging and back opening is effectivelyachieved; and the transmission efficiency is high, the force is appropriate, and thus, the requirements of a human body on comfort are better met.

[0002] Modern people live a busy life, and the only time they have free time is to go home and rest, so most people often don’t want to go out again when they get home, but there is no way to relieve the back pain caused by busy work and work pressure. Therefore, there is The industry has developed an existing massager to provide consumers with a massage at home to relieve fatigue and backaches

[0003] The existing massage movement includes a motor, a worm gear box and a kneading head. After the output of the motor is decelerated by the worm gear box, the output shaft drives the kneading head to rotate. It generally uses the massage head to rotate or swing to achieve the purpose of massage. Unable to satisfy people's pursuit of diversified massage techniques

[0004] CN201620563125X discloses a double-swing massage movement, including a frame, an open back arm, a turntable, a worm gear box and a motor. One end of the open back arm is movably sleeved on the eccentric shaft of the turntable, and the other end is slidably positioned on the frame beam. On the pin, a swing constraint is formed; wherein: the open back arm is provided with an arc-shaped slot, and the positioning pin passes through the arc-shaped slot to constrain one end of the open back arm, and a warp is positioned on the open back arm by the guide shaft. Plate-type massage head, although the patent realizes a certain self-adaptive 3D massage by means of the seesaw-type massage head and swing arm at the end of the open back arm, but the structure of the seesaw-type massage head is complicated to connect, and the three-dimensional concave-convex when installed in the seat The tilting effect is poor and cannot meet the comfort requirements of the human body

Moreover, its overall installation and disassembly are inconvenient, and the range of undulation and swing is not large, which cannot meet the needs of opening the back
