Abstract

Presented is an automatic trailer hitch for enabling removable coupling between a towing vehicle and a towed vehicle. The automatic trailer hitch includes a base module, a vertical climbing module, linchpin modules configured for selectively driving the linchpins in an engaged position and a disengaged position, and a rotation module. The vertical climbing module is configured to vertically displace a hitch along a single axis. The plurality of linchpin modules is configured for selectively driving the linchpins in an engaged position and a disengaged position. A controller module is operatively coupled to each of the vertical climbing module, the linchpin modules, and the rotation module to monitor and control the multiple-axis position adjustment of the hitch(s) of the automatic trailer hitch.

2 . The automatic trailer hitch ( 100 ) according to claim 1 , wherein the block ( 20 ) is substantially L-shaped.

3 . The automatic trailer hitch ( 100 ) according to claim 1 , wherein the hitch receiver is connected to at least one of: a towing vehicle and/or a towed vehicle.

4 . The automatic trailer hitch ( 100 ) according to claim 1 , wherein the carriage ( 30 ) is substantially U-shaped.

5 . The automatic trailer hitch ( 100 ) according to claim 1 , wherein the motion-sensing mechanism includes an optical rotary encoder that is configured to sense movement of at least one of: the output gear ( 238 ) and/or the input gear ( 234 ).

6 . The automatic trailer hitch ( 100 ) according to claim 1 , wherein the vertical climbing module ( 200 ) is configured to vertically adjust the hitch(s) ( 450 ) along a single axis.

7 . The automatic trailer hitch ( 100 ) according to claim 1 , wherein the vertical climbing module ( 200 ) further comprises a plurality of bearings and screws.

8 . The automatic trailer hitch ( 100 ) according to claim 1 , wherein the motor ( 220 ) includes at least one of: a servomotor and a stepper motor.

9 . The automatic trailer hitch ( 100 ) according to claim 1 , wherein the motor ( 220 ) further comprises a potentiometer that is configured to act as a motion sensing mechanism of the vertical climbing module ( 200 ).

10 . The automatic trailer hitch ( 100 ) according to claim 1 , wherein the mechanical linkage ( 230 ) includes at least one of: chain and sprocket linkage, gear linkage, rope and pulley linkage, and belt and pulley linkage.

11 . The automatic trailer hitch ( 100 ) according to claim 1 , wherein the linchpin module ( 300 ) comprises a brace plate ( 320 ) and a nut plate ( 330 ) actuated by a rotating lead screw ( 340 ) and a driving motor ( 360 ).

12 . The automatic trailer hitch ( 100 ) according to claim 1 , wherein the motion sensing mechanism of the linchpin module ( 300 ) comprises a plurality of terminal roller-actuated micro-switches ( 350 ).

13 . The automatic trailer hitch ( 100 ) according to claim 1 , wherein the rotation motor ( 410 ) includes at least one of: a servomotor and/or a stepper motor.

14 . The automatic trailer hitch ( 100 ) according to claim 1 , wherein the rotation motor ( 410 ) further comprises a potentiometer that is configured to act as a motion sensing mechanism of the rotation module ( 400 ).

15 . The automatic trailer hitch ( 100 ) according to claim 1 , wherein the hitch(s) ( 450 ) is selected from a group of hitches comprising of: ball hitch, pintle hitch, gooseneck hitch, boom hitch, receiver hitch, hook type hitch, lunette ring hitch, and Janney couplers.

16 . The automatic trailer hitch ( 100 ) according to claim 1 , wherein the user interface ( 510 ) of the controller module ( 500 ) includes at least one of: touchscreen interface, joystick interface, remote, keyboard interface, switch interface, and button interface.

17 . The automatic trailer hitch ( 100 ) according to claim 1 , wherein the controller module ( 500 ) further comprises a camera ( 510 ) to visually assist the user in enabling coupling between a towing vehicle and a towed vehicle.
