The present specification generally relates to window controllers for motorized windows and, more particularly, to window controllers that are portable and can be carried between vehicles.
Window lift assemblies are often used in vehicles for raising and lowering of windows between open and closed positions using an actuator, such as a motor. Window regulators for use in automobiles often include a link mechanism or wire mechanism mounted in a door and coupled to a bracket fixed to a panel of window glass attached the door. When raising or lowering the window glass, the link mechanism or wire is moved by a motor-driven actuator to impart vertical movement to the bracket and the window glass connected thereto.
Sometimes during vehicle assembly, there may be an issue with the operation of a window lift assembly. It may be desirable to troubleshoot the window lift assembly. However, the window lift assembly may not yet be inside the vehicle or inside the vehicle, but not yet wired to controls and/or a battery.
Accordingly, a need exists for portable window controllers that can be used to operate window lift assemblies and actuate their associated window regulators.
In one embodiment, a portable window controller for operating window lift assemblies of multiple vehicles includes a controller housing that is sized to fit in a hand and a control switch that extends outward from the housing and can be actuated by the hand. The control switch is a momentary switch that is biased toward a home position and terminates power to a regulator motor when the control switch is placed in the home position.
In another embodiment, a method of operating a window regulator assembly is provided. The method includes actuating a control switch of a portable window controller that is electrically connected to a regulator motor of the window regulator assembly. The actuation of the control switch moves a regulator carriage of a regulator in a first direction. The control switch is released. The control switch is biased toward a home position. Power to the regulator motor is automatically terminated when the control switch returns to the home position.
These and additional features provided by the embodiments described herein will be more fully understood in view of the following detailed description, in conjunction with the drawings.
The embodiments set forth in the drawings are illustrative and exemplary in nature and not intended to limit the subject matter defined by the claims. The following detailed description of the illustrative embodiments can be understood when read in conjunction with the following drawings, where like structure is indicated with like reference numerals and in which:
Embodiments described herein generally relate to portable window controllers that are used to operate window lift assemblies of multiple vehicles. The portable window controllers include a controller housing that is sized to fit in a hand and a control switch that extends outward from the housing and can be actuated by the hand. The control switch may be a momentary switch that is biased toward a home OFF position. The control switch automatically cuts power to a regulator motor when the control switch is placed in the home position, either manually or by the bias provided by a biasing member, such as a spring.

A regulator cable 30 is connected to the regulator carriage 24. The regulator cable 30 slides around end pulleys 32. A regulator motor 34 moves the regulator cable 30 back and forth. The regulator cable 30 extends through protective sleeves 36 and 38 and is operatively connected to a drive mechanism 40 (e.g., a wheel) that is driven by the regulator motor 34. The regulator motor 34 also includes a motor housing 42 and an input 44 where power and a controller can be connected to regulator motor 34 for controlling the regulator motor 34.
A portable window controller 50 is connected to the input 44 by one or more cables 52 and a releasable connector, represented by element 54. The portable window controller 50 includes a controller housing 56 that is sized to fit in one's hand. A clip 57 or other suitable fastening device may be used to carry the portable window controller 50. A control switch 58 extends outward from the controller housing 56 and is accessible to be actuated by hand. The control switch 58 may be a momentary switch that is biased toward a home OFF position, as illustrated by
A display 60 is mounted to the controller housing 56. The display 60 may be any suitable type, such as an LED display. The display 60 may be connected to a power measuring module, represented by element 62 that can measure power properties, such as voltage, current, etc. (e.g., a Volt meter) of power coming into the portable window controller 50. Indicator lights 64 and 66 is also provided that can be located adjacent opposite sides 68 and 70 of the control switch 58. The indicator lights 64 and 66 may illuminate different colors to provide a visual indication of operation of the portable window controller 50, as will be described in greater detail below.
The portable window controller 50 connects to an external battery using one or more cables 72. Another releasable connector 74 is provided for connecting to a corresponding connection of the battery. The display 60 can display a power property of the battery during operation, such as a voltage. The display 60 can be used to determine an operating condition of the battery to readily see when the battery may need to be replaced. Once the portable window controller 50 is connected to both the regulator motor 34 and the battery, the portable window controller 50 can be used to operate the window regulator assembly 12.

The above-described portable window controllers provide a personal controller for operating window lift assemblies. The portable window controllers can be connected to regulator motors of different vehicles in order to troubleshoot an issue by operating the window lift assemblies. The portable window controllers can be light and small enough to carry by hand or be carried on a belt or belt loop for easy access. The portable window controllers may include a display connected to a power measurement module for measuring voltage or other power property and then displaying the measurement value. The personal window controllers may be operating using a momentary switch that automatically cuts power to the regulator motor when in the home position.
While particular embodiments have been illustrated and described herein, it should be understood that various other changes and modifications may be made without departing from the spirit and scope of the claimed subject matter. Moreover, although various aspects of the claimed subject matter have been described herein, such aspects need not be utilized in combination. It is therefore intended that the appended claims cover all such changes and modifications that are within the scope of the claimed subject matter.
