Abstract
Description
Technical Field
[0001] The object of the present invention relates to an inductive coupling charging device for a window lift system of a vehicle door and a window lift system comprising said charging device. Background Art
[0002] Automotive side glass has traditionally been clear or, in some cases, permanently tinted.
[0003] Recently, technological developments from other technical fields, such as those of architecture or decoration, have reached the automobile, as in the example of active glass that darkens on demand and by receiving an electric current.
[0004] Active glass has begun to find its way into the sunroofs of vehicles. However, there are technical problems when it comes to inserting active glass in the side doors of vehicles because active glass is driven by an electric current, while conventional glass in the side doors of vehicles is mobile and is located on a window lift system that allows it to move (i.e. up and down). Therefore, replacing active glass with conventional glass in the window lift system and applying the electric current presents complex technical challenges.
[0005] The present invention proposes a solution to the aforementioned technical drawbacks of incorporating active glass into vehicle side doors. Summary of the invention
[0006] The invention obtains a solution to the technical problems associated with the implementation of active glass in the door of a vehicle by means of an inductively coupled charging device comprising a pair of inductive elements allowing the transmission of electrical energy to the active glass window in a manner that minimizes the problems to which the moving elements are subjected (noise, vibrations, humidity, direct ingress of water, dust, salt environment (corrosion), etc.).
[0007] The present invention allows the glass to be activated when two elements (ie a pair of inductive elements) are facing each other, typically when the glass is in a closed position.
[0008] Therefore, in a first aspect, the present invention relates to an inductively coupled charging device for a window lift system for a vehicle door. The window lift system comprises an active system comprising an active glass window.
[0009] The inductively coupled charging device comprises a transmitter coil including a connection connectable to a current source of the vehicle, wherein the transmitter coil is configured to be charged by the current source. The inductively coupled charging device also comprises a receiver coil connectable to an active system.
[0010] The inductive coupling charging device is configured to drive the active glass window by a current obtained by inductive coupling between the transmitter coil and the receiver coil in a charged state. The driving of the active glass window causes the active glass window to darken.
[0011] The inductively coupled charging device also includes control electronics configured to transfer energy between the transmitter coil and the receiver coil.
[0012] The window lift system may comprise a drag car, and wherein the receiving coil may be connected to the drag car.
[0013] In a second example, the receiving coil may be connected to an active glazing of an active system.
[0014] The window lift system comprises a track configured to allow the active glass window to be moved by a drag mechanism, and wherein a transmitting coil is connectable to the track.
[0015] In another example, the transmitter coil may be connected to a vehicle door.
[0016] In another example, the transmitter coil wiring may include a charging connector connectable to an energy source.
[0017] Another aspect of the present invention relates to a window lift system for a vehicle door, wherein the window lift system comprises an inductive coupling charging device according to the first aspect of the present invention. The active system comprises an active glass window, a drag mechanism for the active glass window, and a track on which the active glass window moves by the drag mechanism.
[0018] In one example, the transmitter coil is connected to the track. In another example, the transmitter coil is connected to a door of the vehicle.
[0019] In other examples, the receiving coil is connected to an active glazing pulling mechanism or directly to an active glazing of an active system. BRIEF DESCRIPTION OF THE DRAWINGS
