Luggage braking system and luggage with such braking system

Abstract

This invention provides a braking system and a luggage compartment incorporating the braking system. The luggage compartment includes a handle and a plurality of wheels. The braking system includes a signal transmitter mounted on the handle, a control unit, and a brake unit mounted on one of the wheels. The control unit has a signal receiver, a controller electrically connected to the signal receiver, a motor electrically connected to the controller, a gear driven by the motor, and a rack meshing with the gear. The brake unit has a brake cable linked to the rack and a brake element controlled by the brake cable. The signal transmitter can transmit a braking signal or a brake release signal to the signal receiver to control whether the brake element is engaged. Therefore, the user only needs to operate the signal transmitter on the handle to engage or disengage the brake.

Claims

1. A luggage braking system applied to a luggage, the luggage including a body, a handle assembly partially disposed in the body, and a plurality of wheels located on the bottom surface of the body, the braking system comprising: a signal transmitting unit disposed on the handle assembly and having an operating element, and a signal transmitter electrically connected to the operating element, wherein operating the operating element controls the signal transmitter to transmit a braking signal or a brake release signal; A control unit, disposed inside the housing, includes a signal receiver for receiving the braking signal and the brake release signal, a controller electrically connected to the signal receiver, a motor electrically connected to the controller, a gear driven by the motor to rotate, and a rack meshing with the gear; and a braking unit, disposed on a roller, including a brake cable connected to the rack, and a brake element disposed on the roller and controlled by the brake cable, wherein the braking signal causes the brake element to engage braking, and the brake release signal causes the brake element to release braking.

2. The braking system as described in claim 1, wherein, The operating element is a self-locking button or a slide switch.

3. The braking system as described in claim 1, wherein, The braking signal and the brake release signal are transmitted via infrared or Bluetooth.

4. The braking system as described in claim 3, wherein, The braking signal and the brake release signal are transmitted using infrared light.

5. The braking system as described in claim 4, wherein, The braking signal and the brake release signal are transmitted through a hollow channel within the handlebar assembly.

6. The braking system as described in claim 4, wherein, The handle assembly contains a positioning block made of a transparent material.

7. The braking system as claimed in claim 4 further includes an infrared transmission strip connecting the signal transmitter and the signal receiver.

8. The braking system as described in claim 1, wherein, The braking device has a brake connected to the brake cable and a retaining ring connected to the roller, the retaining ring having a plurality of grooves for engaging the brake.

9. The braking system as described in claim 8, wherein, It also includes an adjustment unit having an active member connected to the rack, a passive member connected to the brake cable, and an elastic body that abuts the active member and the passive member respectively.

10. The braking system as described in claim 9, wherein, The passive component has a frame connected to the brake cable and a passive protrusion located within the frame; the active component has a groove for sliding the passive component and an active protrusion extending outward from the groove into the frame, and the elastic body abuts against the passive protrusion and the active protrusion respectively.

11. The braking system as described in claim 1, wherein, It also includes a power supply unit having a power supply device and a power supply controller electrically connected to the power supply device and the controller respectively.

12. The braking system as described in claim 11, wherein, The power supply controller is a vibration detector.

13. A suitcase comprising: a case body; a handle assembly partially disposed within the case body; a plurality of wheels located on the bottom surface of the case body; and a braking system as described in any one of claims 1 to 12.
