For example, the sensor bracket 164 may be bolted to the upper plate of the take-up reel bracket 151 or may be fixed to the guide wheel bracket 161. One of the proximity sensors 163 (e.g., the left or innermost sensor in fig. 6) is near the initial position of the pilot axle 165 sliding in the limit slot, and the other proximity sensor 163 is near the end position of the pilot axle 165 sliding in the limit slot.

In use, when the caregiver manually pulls the latch arm 130 outwardly, the flexible strap also moves outwardly, the guide wheel 162 is forced inwardly, and after the first proximity sensor 163 (corresponding to the leftmost initial position in the limiting slot) senses, the motor is reversed, releasing the flexible strap. When the buckling arm 130 extends out, the flexible belt is not pulled any more, the guide wheel 162 returns under the action of the elastic piece 166, the other proximity sensor 163 (corresponding to the end position at the rightmost side in the limit slot) senses that the motor stops rotating, and the number of the proximity sensors 163 can be 1 or replaced by a limit switch.

In order to solve the problem that the holding force of the hip holding device is changed along with the change of the gravity center of the shifter in the lifting process of carrying passengers, the tightening mechanism of the embodiment of the invention further comprises a force sensor for measuring the tightening degree of the flexible belt or indirectly measuring the holding force of the holding arm, the force sensor transmits a measured force signal to a processor, and the processor drives a controller to control a motor so as to change the winding force and length of the winding wheel, thereby forming a closed-loop control system. The force sensor may be a tension sensor, a pressure sensor, a torque sensor, or the like.

In some embodiments, as shown in fig. 5, a deformation member 171 is interposed between the reel bracket 151 and the rotation arm 120, for changing the distance between the reel bracket 153 and the rotation arm 120 when the tension applied to the reel 153 is changed. Wherein the deformation member 171 is a pressure sensor or a pressure sensor is installed at the deformation member 171. The pressure sensor is used for collecting the pressure between the winding wheel bracket 151 and the fixed rotating arm 120, and can measure the pressure born by the cohesion arm or the cohesion force applied by the cohesion arm. In some embodiments, the deformation member may be an elastic pad, a spring member, or the like.

In other embodiments, the force sensor may also be a tension-compression sensor, or may be a rigid structure to connect the left and right arms for achieving the purpose of rotating the arms at the same time. In embodiments of the present invention, the force sensor may be disposed in a rigid structural member herein. For example, a deforming member 171 is interposed between the reel bracket 151 and the rotating arm 120 for changing the distance between the reel bracket 153 and the rotating arm 120 when the tension applied to the reel 153 is changed. The force sensor 172 is mounted between the brackets of the reel 153 inside the two-sided clasping arms by a rigid link 173.

In the above embodiment, the force sensor may be disposed at the central axis of the winding reel 153, and in this case, the force sensor may be a torque sensor, and the force sensor may be disposed at the guide wheel 162 or the guide wheel support 161, and the feedback signal required for closed loop control may be obtained by converting the displacement of the guide wheel 162 or the guide wheel support 161 into a force signal.

According to the tightening mechanism, when the shifter bears the displacement of the shifter in the vertical direction or the horizontal direction in space, the phenomenon that the embracing effect is poor due to the change of the gravity center caused by the change of the angle position can be achieved, namely the induction type embracing device can achieve the function of real-time tightening, so that the shifter can ensure approximately the same embracing force in all shifting processes, and the comfort level of the shifter is increased. The hip-holding device in the embodiment of the invention is also beneficial to ensuring the stable cohesion of the whole displacement process, so that a person who moves can not loose the hip-holding device and the safety is improved.

In some embodiments, the buckling arm 130 may be configured as an arc arm with concave shape to adapt to the human body curve of the back waist or hip of the human body, and an anti-slip layer may be disposed on the inner side of the buckling arm 130, where the anti-slip layer may be a coating, a pitted surface layer, or an anti-slip material wrapping layer.

In the embodiment of the invention, the rotation of the embracing arm can be realized by manual assistance of a nursing staff and can be realized by downward pressing of the nursing staff. The belt wheel assembly 150, the guide wheel assembly 160, etc. of the hip-embracing device of the embodiment of the invention are arranged at the rear side of the lying platform, the front side of the embracing arm is only provided with the buckling arm 130, and the first connecting shaft is arranged at the rear part, so that the front part is light and the rear part is heavy. When the shifting process is finished, the person leaves the hip-holding device, and the rear part of the rotation center point is heavier than the front part of the rotation center point, so that the arm can return automatically after being pressed down to be released. The cohesion arms on both sides are same movement, namely pressing one side, the other side will follow the movement.
