Handle head and carrier with the same

The present disclosure relates to a handle component of a fully automatic or semi-automatic logistics vehicle, in particular to a handle head and a carrier in with the same.

Carriers, for example in the form of pallet trucks and the like, are widely used in the field of logistics transportation. The conventional handle heads of electric carriers are large in size and complex in function. The internal functional components and wiring harnesses are staggered, and the internal structural configuration tends to be disorganized. In turn, this makes the assembly process cumbersome, and the electromagnetic elements are more easily subject to failure. In addition, when a handle fails in a given work location, it can be difficult to repair. Most carrier vehicles require at least the transportation function, although maintaining an operational lifting function also is desirable. Thus, there is a problem in the art with the probability of handle operational failure and a need to reduce the maintenance difficulty of a handle head, some of which relates back to present technical difficulties with handle assembly in this field.

In order to solve the above technical problems, a first object of the disclosure is to provide an improved handle head. The handle head is divided into a plurality of functional areas by an isolation component.
