In other words, one of the grip group 0200 and the carrier group 0300 is movably coupled to the second sensor 0410 for relative motion, and the other is fixedly coupled to the second sensor 0410. Under this structure, when the holding group 0200 or the carrying group 0300 is slightly shaken or twisted, the second sensor 0410 still has a certain adaptive adjustment space, so as not to be stuck or broken.

Referring to FIG. 8, a handling device 10000 will be described herein. The handling device 10000 has a hoisting main body 2000, a rotating folding arm 3000 and the above-mentioned induction handle 1000. The hoisting main body 2000 is wound with a flexible member 4000 on the surface thereof, and the flexible member 4000 is tensioned on the rotating folding arm 3000 and the second End 0320 is connected.

In particular, the flexure 4000 can be in the form of a drive train, a drive belt, a drive line, and the like. In an exemplary embodiment, the flexure 4000 is a wire rope. The second end 0320 is provided with a collar 0325, and the flexible member 4000 is wound around the collar 0325. When the inductive handle 1000 senses the user's intent to move, the handling device 10000 will make a determination.

If the driving load of the user is in the horizontal direction, the turning arm 3000 rotates under the driving load, and the horizontal position of the weight changes.

If the driving load of the user is in the vertical direction, the sensing handle 1000 senses the measured displacement and outputs a detection signal to the hoisting host 2000. The hoisting main body 2000 retracts the flexure 4000 and applies a lifting load to the weight to change the vertical position of the weight.

At the same time, the sensing group 0400 can measure the displacement of the holding group 0200 under the driving load, and the control system can calculate the driving load size, and adjust the hoisting speed of the hoisting host 2000 accordingly, thereby achieving precise control of the lifting speed.

Since the second sensor 0410 is directly disposed on the sensing handle 1000, it belongs to the direct measurement mode, which can eliminate the interference of the switching mechanism gap and damping caused by the indirect measurement mode, and the data transmission path is short, thereby avoiding interference distortion during data transmission. The function of ensuring the user's intention of motion is accurate and sensitive.

Example 2

The difference between this embodiment and Embodiment 1 is that the second sensor 0410 of the present embodiment takes the form of a force sensor. Accordingly, the second penetration portion 0210 has a different structure.

Referring to FIGS. 9-10 together, the second sensor 0410 is a force sensor, which can directly measure the value of the driving load and convert it into an electrical signal and output it to the driving host. The driving host outputs the feedback force according to the data of the driving load, so that the weight obtains the corresponding displacement or moving speed, and realizes the handling of the heavy object.

Correspondingly, the second through portion 0210 remains integrally penetrated and has a clearance fit with the load transmitting portion 0330 so as to have a relative motion between the holding group 0200 and the carrying group 0300, providing a motion basis for acquiring the driving load of the user. Here, the force sensor has excellent sensitivity and quickly senses the driving load.
