Remote-controlled electric golf bag cart

摘要

A remote-controlled electric golf bag cart has a remote control, a support frame, an antenna set and a control module. The remote control transmits a distance measurement signal. The support frame has a wheel assembly, a golf bag stand and a motor assembly mounted thereon. The antenna set and the control module are mounted on the support frame. The antenna set receives the distance measurement signal. The control module determines an orientation and a distance of the remote control according to the distance measurement signal received by the antenna set, and drives the motor assembly to move the support frame forward toward the remote control, making the support follow a user having the remote control and preventing other in-field persons and obstacles from affecting the support frame to follow the remote control.

主权项

1. A remote-controlled electric golf bag cart comprising:
a remote control transmitting a distance measurement signal; a support frame having a wheel assembly, a golf bag stand and a motor assembly, wherein the motor assembly is connected with the wheel assembly to drive the wheel assembly; an antenna set mounted on the support frame, having:
a mounting base securely mounted on a top of a front end of the support frame;multiple antenna units securely and erectly mounted on the mounting base, and respectively facing to a front side, a left side, a right side, a left front side and a right front side of the support frame, and receiving the distance measurement signal transmitted from the remote control with the antenna units; andan antenna-switching unit electrically connected to the antenna units; and a control module mounted on the support frame, electrically connected to the antenna set and the motor assembly, and setting a minimum distance, determining an orientation of the remote control with respect to the antenna set after acquiring the distance measurement signal received from the antenna set, calculating a distance between the remote control and the antenna set, and comparing the distance with the minimum distance, and if the distance is greater than the minimum distance, controlling the motor assembly to drive the wheel assembly for the support frame to approach the remote control.
