Abstract

Power machines and loaders having doors with an integrated display that allows the display of information, such as gauges, user inputs, mapped obstacles, boundaries, etc., that allows the operator of the machine to see the displayed information closer to the line of sight with the work area. The display can show augmented reality information about a worksite.

First claim

What is claimed is:

1. A power machine comprising:
a cab having a cab frame with an aperture formed on the cab to allow ingress into or egress from an operating station in the cab;
a cab door coupled to the cab and being positionable between a closed position, in which the cab door covers at least a substantial portion of the aperture to prevent ingress and egress and an open position, in which the cab door is positioned to allow ingress and egress, the cab door including a layer of transparent material;
a controller; and
a display integrated on the cab door and in electrical digital communication with the controller, the display having display material configured to allow at least partial visibility through the display material of a work area outside of the cab, the display further configured to display operational information to an operator of the power machine under control of the controller, wherein the display is attached to a surface of the layer of transparent material.

2. The power machine of claim 1 , and further comprising an electrical cable including a plurality of conductors in communication with the controller and the display integrated on the cab door, wherein the electrical cable is capable of moving to maintain communication between the controller and the display when the cab door moves between the open and closed positions.

3. The power machine of claim 2 , wherein the cab door is coupled to the cab by hinges such that the cab door is pivotable between the closed and open positions, and wherein the electrical cable extends between the cab door and the cab frame proximal to at least one of the hinges.

4. The power machine of claim 2 , wherein the cab door is coupled to the cab by rigid linkages that define a path of the cab door between the closed and open positions, wherein in the open position the cab door is located above a seat of the operator station.

5. The power machine of claim 1 , wherein the display integrated on the cab door is configured to display augmented control information including being configured to display mapped obstacles or obstructions from a pre-defined position of an operator positioned in the operating station of the cab.

6. The power machine of claim 1 , and further comprising a layer of input sensing material positioned in alignment with the display capable of sensing an operator's intention of selecting a portion of the display and in response to sensing an operator touching the material providing coordinates related to the display to the controller.

7. The power machine of claim 6 , wherein the display and controller are configured to allow the operator, by the input through the layer of input sensing material, to select areas on the door where operational information or user inputs are displayed.

8. The power machine of claim 6 , wherein the input sensing material is capable of sensing an operator touching the input sensing material.

9. The power machine of claim 6 , wherein the input sensing material is capable of sensing an operator or an object manipulated by an operator in close proximity to the input sensing material.

10. The power machine of claim 1 , wherein the display is integrated into a concave portion of the door.

11. The power machine of claim 1 , and further comprising a second display integrated on a glass window on a side of the power machine.

12. A power machine comprising:
a cab having a cab frame;
a controller; and
a transparent surface on a side of the cab, wherein the transparent surface includes a layer of transparent material; and
a display coupled to the transparent surface, the display having display material configured to allow at least partial visibility through the display material of a work area outside of the cab, the display further configured to display operational information, to an operator of the power machine, under control of the controller, wherein the display is attached to a surface of the layer of transparent material.

13. The power machine of claim 12 , wherein the transparent surface includes first and second layers of transparent material, and wherein the display is integrated between the first and second layers of transparent material.

14. The power machine of claim 12 , wherein the display coupled to the transparent surface is configured to display augmented control information.

15. The power machine of claim 14 , wherein the display being configured to display augmented control information includes the display being configured to display mapped obstacles or obstructions from a pre-defined position of an operator positioned in an operator seat of the cab.

16. The power machine of claim 12 , and further comprising infrared light curtain devices projecting an infrared light curtain proximate the transparent surface in alignment with the display and, in response to sensing an object interrupting the infrared light curtain, the infrared light curtain provides coordinates related to the display to the controller where the light curtain is interrupted.

17. The power machine of claim 16 , wherein the display and controller are configured to allow the operator, by input through the sensing the object using the infrared light curtain, to select areas on the door assembly where operational information or user inputs are displayed.

18. A power machine comprising:
a cab having a cab frame;
a transparent surface coupled to the cab frame;
a controller;
a display coupled to the transparent surface, the display having display material configured to allow at least partial visibility through the display material of a work area outside of the cab, the display further configured to generate images to display operational information, to an operator of the power machine, under control of the controller; and
a layer of input sensing material positioned in alignment with the display and configured to sense an operator touching the layer of input sensing material and to responsively provide information to the controller.

19. A power machine comprising:
a cab having a cab frame;
a controller; and
a transparent surface on a side of the cab; and
a display coupled to the transparent surface, the display having display material configured to allow at least partial visibility through the display material of a work area outside of the cab, the display further configured to generate images to display operational information, to an operator of the power machine, under control of the controller; and
infrared light curtain devices projecting an infrared light curtain proximate the transparent surface in alignment with the display and, in response to sensing an object interrupting the infrared light curtain, the infrared light curtain provides coordinates related to the display to the controller where the light curtain is interrupted.

20. The power machine of claim 19 , wherein the display and controller are configured to allow the operator, by input through the sensing the object using the infrared light curtain, to select areas on the door assembly where operational information or user inputs are displayed.
