Abstract
Disclosed herein are a cart handle assembly with power assist function, which enables a user to easily move a cart by detecting a direction, in which a user's force is applied, to assist power in that direction, and a cart having the same. According to the disclosure, it is possible to improve user's convenience since a user can easily move a cart by detecting a direction, in which a user's force is applied, to provide an assist force (power assist function) in that direction.

-18. (canceled)
A cart handle assembly, comprising:
- a handle bar locatable at one side of a cart to receive an external force in a direction of movement of the cart, the handle bar including a first side and a second side;
- and
- a force sensing module including:
- a connection bracket located at the first side and the second side of the handle bar and configured to be provided on a body of the cart, the connection bracket being moved in a direction of the external force to the handle bar;
- a force sensor coupled to the connection bracket to detect a direction of movement of the connection bracket;
- and
- a support frame supporting the force sensor.
