As shown in fig. 1, 2, 3 and 4, the present invention provides a movement of a massage chair capable of stopping automatically when meeting a block, comprising:
a movement frame 1;
the massage guide seat 2 is arranged on the movement frame 1, and the massage guide seat 2 is provided with a central hole;
the massage rotating shaft 3 is rotatably arranged in the center hole of the massage guide seat 2 in a penetrating way;
the massage head 4 is arranged at one end of the massage rotating shaft 3 extending out of the massage guide seat 2;
the detection system 5, the detection system 5 includes a controller 51, a hall sensor 52 and a magnetic field generator 53, the hall sensor 52 is connected with the controller 51 in a communication way and is arranged on the massage guide seat 2, the magnetic field generator 53 is arranged on the massage head 4, and the magnetic field generator 53 and the hall sensor 52 are matched in position in a direction parallel to the axial direction of the massage rotating shaft 3;
and the driving device 6, wherein the driving device 6 is in transmission connection with the massage rotating shaft 3 and is in communication connection with the controller 51.
In the invention, the massage guide seat 2 plays a role in restraining and guiding the massage rotating shaft 3 and does not rotate along with the massage rotating shaft 3. Since the hall sensor 52 is connected to the controller 51 in a communication manner and is disposed on the massage guide base 2, the magnetic field generator 53 is disposed on the massage head 4, and the magnetic field generator 53 and the hall sensor 52 are matched in position in a direction parallel to the axial direction of the massage rotary shaft 3, when the massage rotary shaft 3 rotates relative to the massage guide base 2, the distance between the magnetic field generator 53 and the hall sensor 52 changes periodically, so that the hall voltage generated by the hall sensor 52 changes periodically. The hall sensor 52 feeds back the current change period of the hall voltage to the controller 51 in real time (the controller 51 may comprise a single chip microcomputer), and if the current change period is greater than the preset change period, the controller 51 judges that the massage rotating shaft 3 rotates normally; if the current variation period is not greater than the preset variation period, the controller 51 determines that the massage rotary shaft 3 is blocked (for example, foreign matters are entangled in the massage rotary shaft 3 or the massage head 4), and the controller 51 controls the driving device 6 to stop. Therefore, the machine core of the automatic stop type massage armchair when meeting with a blockage can lead the driving device 6 to automatically stop when the massage head 4 or the massage rotating shaft 3 is blocked, thereby avoiding the damage of the machine core of the automatic stop type massage armchair when meeting with a blockage caused by the continuous operation of the driving device 6.
As shown in fig. 1 and 3, the massage head 4 includes an anti-hooking massage end 41 and a foreign object blocking cover 42, the anti-hooking massage end 41 is connected to the massage rotary shaft 3, the foreign object blocking cover 42 is connected to the anti-hooking massage end 41 and sleeved on the massage rotary shaft 3, the anti-hooking massage end 41 includes a pressing surface portion 411 and a spherical finger portion 412, and the spherical finger portion 412 protrudes smoothly and transitionally from the pressing surface portion 411. The spherical thumb portion 412 protrudes smoothly from the pressing face 411 to prevent the anti-hooking massage end 41 from hooking foreign objects.
Further, the foreign object blocking cover 42 is in a tapered tubular shape, the foreign object blocking cover 42 has a large diameter end and a large diameter end along the axial direction of the massage rotary shaft 3, the large diameter end of the foreign object blocking cover 42 is connected to the outer peripheral edge of the pressing surface 411, so as to be arranged, the foreign object blocking cover 42 can seal one side of the anti-hooking massage end 41 facing the massage guide seat 2, and surround part of the massage rotary shaft 3, thereby effectively preventing the massage rotary shaft 3 or the anti-hooking massage end 41 from hooking the foreign object.
The number of the spherical finger portions 412 is two, and the heights of the two spherical finger portions 412 protruding from the pressing surface portion 411 are different.
The magnetic field generator 53 is a magnet. Further, the magnet may be a permanent magnet.
The driving device 6 comprises a motor 61 and a transmission component, and the motor 61 is connected with the massage rotating shaft 3 through the transmission component.
The above-described magnetic field generators 53 have various arrangements: for example, the magnetic field generator 53 may be embedded in the outer wall of the massage head 4; for another example, the massage head 4 has an accommodating chamber therein, and the magnetic field generator 53 is disposed in the accommodating chamber and on a side of the massage head 4 close to the massage guide 2, so that the smoothness of the outer wall of the massage head 4 can be improved.
As shown in fig. 4, the core frame 1 is provided with a mounting hole 11 having a regular polygon shape, the massage guide 2 includes a main body column 21 and a tray 22, an outer contour of a cross section of the main body column 21 has a regular polygon shape, the main body column 21 is inserted into the mounting hole 11, the tray 22 is provided on the main body column 21, and the hall sensor 52 is provided on the tray 22. Since the outer contours of the cross sections of the mounting hole 11 and the main body column 21 are regular polygons, the main body column 21 cannot rotate relative to the movement frame 1.
In order to improve the comfort level of massage, the machine core of the resistance-meeting self-stopping massage chair also comprises a massage roller group 7, and the massage roller group 7 is arranged on the machine core frame 1.
The invention also provides a blockage detection method of the blockage self-stopping massage armchair movement, which comprises the following steps:
s1, setting a rotation period threshold of the massage rotating shaft 3 or the massage head 4 through the controller 51;
s2, starting the driving device 6, enabling the massage head 4 to synchronously rotate along with the massage rotating shaft 3, and the Hall sensor 52 inducts the position of the magnetic field generating body 53 in real time to measure the current rotation period of the massage rotating shaft 3 or the massage head 4;
s3, judging whether the current rotation period is larger than the rotation period threshold value, if so, the controller 51 judges that foreign matters are entangled in the movement of the self-stop massage chair when meeting the resistance and sends a stop instruction to the driving device 6, and the driving device 6 stops running; if not, the controller 51 determines that the movement of the self-stop massage chair normally operates when encountering a blockage, and jumps back to S2.
The jamming detection method can timely judge whether the massage rotating shaft 3 or the massage head 4 is jammed, if the current rotation period is larger than the threshold value of the rotation period, the controller 51 timely stops the driving device 6, and the damage of the movement of the self-stopping massage chair caused by jamming is avoided.
In summary, the movement of the automatic stop-when-meets massage chair and the jamming detection method thereof of the present invention can make the driving device automatically stop when the massage head or the massage rotating shaft is jammed, thereby preventing the movement of the automatic stop-when-meets massage chair from being damaged due to the continuous operation of the driving device. Therefore, the invention effectively overcomes various defects in the prior art and has high industrial utilization value.
The foregoing embodiments are merely illustrative of the principles and utilities of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or change the above-mentioned embodiments without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
