Embodiment 1

[0042] Embodiment 1: A kind of external rotor motor drive booster, see Figure 1-6 , including traction force acquisition mechanism, load force acquisition mechanism, outer rotor motor assist mechanism, rotational speed acquisition mechanism, and body frame.

[0043] The traction force collection mechanism includes a traction fixed pulley 3 and a traction pressure sensor 5 ; the load force collection mechanism includes a load fixed pulley 2 and a load pressure sensor 4 . One end of the wheel shaft of the traction fixed pulley 3 is connected with the frame 11 through the joint bearing 14, the joint bearing 14 can realize the swing of the wheel shaft within a certain angle and the rotation of the wheel shaft, and the other end is installed on the frame 11 through the rolling bearing 10. At the hole, the left and right swing of the wheel shaft is restricted, and the up and down swing is not limited. Using the rolling bearing 10 can effectively reduce the resistance of the wheel s...

Abstract

The invention discloses a power assisting device driven by an external rotor motor. The labor-saving mechanism aims to solve the technical problems that an existing labor-saving mechanism of a movement protection belt is complex, limited in working stroke, incapable of adapting to rapid working condition changes and the like. The device comprises a cable, a traction wheel pressure sensor, a load wheel pressure sensor, a traction wheel rotating speed sensor, a load wheel rotating speed sensor, an outer rotor motor, a controller and the like. The controller is electrically connected with the pressure sensors and the rotating speed sensor, and the rotating speed and the output torque of the outer rotor motor are controlled through a real-time control algorithm, so that the assisting effect on the pulling force of the cable is achieved. The traction stroke is kept unchanged while the labor-saving effect is achieved, the structure is compact, the integration degree is high, the self-adaption to different driving friction conditions can be achieved, and normal work is kept under the rapidly-changed working condition.

Description

technical field [0001] The invention relates to the technical field of hoisting equipment, in particular to an external rotor motor-driven booster. Background technique [0002] In the field of sports training, protective belts are required in the training process of many sports, such as diving, gymnastics, trampoline, rock climbing and so on. Protective belt is a kind of commonly used sports protection equipment, and its one end is bound on athlete's body, and the other end is held by coach. The coach's control of the protection belt can not only protect the safety of the athletes, but also change the rotation speed of the athletes in the air, prolong the time of the athletes in the air, etc., and help the athletes complete aerial skills. Pulling the protective belt is not only a heavy physical labor, but also the human body required to pull is definitely more important than the person being pulled. These limiting factors have caused many female coaches and old coaches to...
