Clutch drive intelligent following luggage box

Abstract

The invention discloses a clutch drive intelligent following luggage box. A UWB transmitter module is placed on a user, a UWB receiving module is fixed to the front part on the upper part in the luggage box, wheels on either side of the bottom of the luggage box are connected with one end of an axletree of a drive wheel system with the clutch damping function, transmitted signals are received by the UWB receiving module on the luggage box, the distance and the angel between the user and the luggage box are obtained after processing of a signal processing module and fed back to a control system, the signals are output by the control system, thus a clutch is electrified and a motor is driven to operate, a clutch coil is electrified to generate magnetic field adsorption friction plates, the power output by the motor is transmitted to the axletree by meshing with a gear, the wheels are driven to move, and the luggage box is driven to follow the user automatically. The clutch drive intelligent following luggage box has the advantages that the drive wheel structure capable of clutch is adopted, the two functions of pushing travelling and automatic following are achieved, a battery of the luggage is stored and taken from external, and a UWB locating technology with quick response and accurate locating is adopted.

Description

technical field [0001] The invention relates to the technical field of an intelligent following suitcase, in particular to a clutch-driven intelligent following suitcase. Background technique [0002] Most of the existing intelligent following suitcases adopt a six-wheel structure. When walking automatically, the driving wheel descends to fit the bottom surface; when pushing, the driving wheel rises away from the bottom surface. Two more driving wheels are added to the suitcase, which increases the weight of the suitcase; and because the liftable drive wheels must be lower and closer to the ground than the other four wheels, the suitcase will swing back and forth when driving automatically , producing noise and affecting life. [0003] Existing smart battery compartments that follow suitcases to store battery boxes are all placed inside the suitcase. When the power supply is insufficient and need to be charged, the suitcase needs to be opened and the battery box taken out ...

Problems solved by technology

However, the positioning system is complex because each group of radio frequency receiving units has AoA data and RSSI data, and the positioning results need to adopt a fusion strategy, resulting in high cost and low reliability of the system.
