Detailed Implementation

[0016] In this embodiment, a vehicle window glass is provided. The front view of the vehicle window glass, that is, the view of the vehicle interior from outside the vehicle, perpendicular to the line of sight of the window glass, after the window glass has been installed in the vehicle door, is shown below. Figure 1 As shown, this is a top view of the car window, that is, a view taken from a line of sight perpendicular to the ground after the car window has been installed in the door. Figure 2 As shown. (Refer to...) Figure 1 and Figure 2 Car window glass consists of an outer layer, an inner layer, and an interlayer. The outer and inner layers can have the same shape, material, and dimensions (length, width, thickness, etc.). For example, they can be made from materials such as silicate glass or acrylic glass. The outer layer is the glass layer installed behind the car door, facing outwards, while the inner layer is the glass layer installed behind the car door, facing inwards.

[0017] Reference Figure 1 The intermediate layer includes components such as the power generation winding module, transparent wires, and transparent light-emitting elements. The transparent light-emitting element can be a transparent organic light-emitting diode (TOLED) or an inorganic electroluminescent film (IEL). Taking an inorganic electroluminescent film as an example, a transparent light-emitting element made using an inorganic electroluminescent film has a sandwich structure of "transparent electrode + zinc sulfide (ZnS)-based light-emitting layer (doped with manganese / copper) + transparent electrode". When the two transparent electrodes are not energized, both the transparent electrodes and the light-emitting layer are transparent. When energized, i.e., when a sufficient voltage is applied to the two transparent electrodes, the light-emitting layer emits light due to the electroluminescence (EL) effect.

[0018] In this embodiment, the power generation winding module is a coil winding. When a time-varying magnetic field acts on the power generation winding module, the magnetic flux through the power generation winding module changes. Due to the principle of electromagnetic induction, an electromotive force is generated at both ends of the power generation winding module, i.e., the current output terminal. If the current output terminal of the power generation winding module is connected to the load, the power generation winding module can output current to the load through the current output terminal, thereby realizing the power generation of the power generation winding module.

[0019] In this embodiment, refer to Figure 1 Multiple transparent light emitters can be set, with each emitter's two transparent electrodes serving as its current input terminals. The current input terminals of each transparent light emitter can be connected in parallel and then connected to the current output terminal of the power generation winding module. Figure 1 To keep things simple, only one transparent light-emitting element is shown connected to the power generation winding module via a transparent wire. The current input terminals of the other transparent light-emitting elements are connected to the current output terminals of the power generation winding module via transparent wires.

[0020] In this embodiment, transparent conductive oxide (TCO) materials can be used to fabricate the transparent wires. Specifically, transparent conductive oxides such as indium tin oxide (ITO), fluorine-doped tin oxide (FTO), or aluminum-doped zinc oxide (AZO) can be used to fabricate the transparent wires. The transparent wires can guide the current output from the current output terminal of the power generation winding module to the current input terminal of the connected transparent light-emitting element, while the transparent wires themselves remain transparent regardless of whether they are energized.

[0021] In this embodiment, refer to Figure 2 The intermediate layer is sandwiched between the outer and inner glass layers.

[0022] In this embodiment, the transparent light-emitting element is the load of the power generation winding module, and the power generation winding module is the sole power source for the transparent light-emitting element. When no time-varying magnetic field acts on the power generation winding module, the power generation winding module does not generate electricity, that is, it does not output current to the transparent light-emitting elements, and the transparent light-emitting elements remain transparent without emitting light. When a time-varying magnetic field acts on the power generation winding module, the power generation winding module generates electricity, that is, it outputs current through its current output terminal. The current is conducted through transparent wires to the current input terminals of the transparent light-emitting elements, thereby causing the transparent light-emitting elements to emit light.

[0023] In this embodiment, in addition to connecting the current input terminal of the transparent light-emitting element directly to the current output terminal of the power generation winding module via a transparent wire, it is also possible to refer to... Figure 1 The current input terminal of the transparent light-emitting element is connected to the current output terminal of the power generation winding module through a transparent wire and a resistor. That is, for any transparent light-emitting element, the transparent light-emitting element, the resistor, and the power generation winding module are connected in series. By setting the resistor, the voltage output by the power generation winding module can be reduced, preventing the voltage generated by the power generation winding module from being directly applied across the transparent light-emitting element.

[0024] In this embodiment, refer to Figure 1 When multiple transparent light-emitting elements are used, they can be arranged to form the shape of a first character. In this embodiment, the first character is text indicating a request for help, for example... Figure 1 Chinese "Help" as shown, or English "HELP", etc.

[0025] In this embodiment, when only one transparent light-emitting body is provided, this one transparent light-emitting body can be made into a sufficiently large area, and the shape of this one transparent light-emitting body can be made into the shape of the above-mentioned first character.

[0026] In this embodiment, referring to Figure 1 , the power generation winding module can be set at the position corresponding to the edge of the outer glass and the inner glass, and each transparent light-emitting body is located at the position corresponding to the center of the outer glass and the inner glass. In this way, even if the power generation winding module is not transparent, it will only make a part of the edge of the overall window glass opaque, and when the power generation winding module is not affected by the time-varying magnetic field, the transparent light-emitting body and the transparent wire are both transparent. Therefore, the central part of the overall window glass, that is, the other part of the overall window glass except the edge part, is transparent.

[0027] In this embodiment, the Figure 1 shown window glass can be installed on the door, and a window regulator and a magnet can be installed on the door, thus jointly forming a door system.

[0028] In this embodiment, the structure of the door system is as shown in Figure 3 . Referring to Figure 3 , the door system includes a door, and the door is provided with a window frame and a receiving cavity. The window frame encloses the window of this door, which is the position where the window glass extends out of the receiving cavity; the receiving cavity is the space inside the door, which can provide a receiving space for the window glass, so that the window glass can retract into the receiving cavity. When the window glass extends out of the receiving cavity to the space enclosed by the window frame, it corresponds to the action of closing the window; when the window glass retracts from the space enclosed by the window frame into the receiving cavity, it corresponds to the action of opening the window.

[0029] In this embodiment, referring to Figure 3 , the window regulator is installed in the receiving cavity. The Electronic Control Unit (ECU) on the vehicle can send a control command to the window regulator, thereby controlling the window regulator to drive the window glass to rise or fall. When the electronic control unit sends a rising control command to the window regulator, the window regulator drives the window glass to rise to the area within the window frame, thereby automatically performing the action of closing the window; when the electronic control unit sends a falling control command to the window regulator, the window regulator drives the window glass to fall and thus enter the receiving cavity, thereby automatically performing the action of opening the window.

[0030] In this embodiment, a permanent magnet or an electromagnet can be used as the magnet. Referring to Figure 3Multiple magnets can be set up and placed in the accommodating cavity. The magnets are arranged in the direction of the power generation winding module in the window glass when the window glass is raised or lowered, so that the magnetic lines of force generated by each magnet can pass through the power generation winding module.

[0031] In this embodiment, it can be said that Figure 3 The door system shown is installed on the car, making the door system an integral part of the car with other components. The electronic control unit on the car is configured so that it can execute a control method for the door system.

[0032] In this embodiment, refer to Figure 4 The control method executed by the electronic control unit includes the following steps: S1. Detect emergency situations in the vehicle; S2. If no emergency event is detected, detect the window lift command; S3. In response to a window lifting command, control the window regulator to drive the window glass to rise or fall at a second lifting rate; S4. When an emergency is detected, control the window regulator to drive the window glass to repeatedly rise and fall at a first lifting rate.

[0033] In step S1, the electronic control unit (ECU) can utilize sensors on the vehicle to detect emergency events. Emergency events include events that cause driver incapacity, or the event of driver incapacity itself. Specifically, the ECU can utilize collision sensors for detection. When a collision exceeding a threshold is detected between the vehicle and an external obstacle, an emergency event is confirmed. The ECU can also utilize occupant status sensors to detect the driver's vital signs, facial expressions, and limb movements. If the detected vital signs, facial expressions, and limb movements exhibit characteristics of cardiovascular diseases or other conditions that can lead to incapacity, or if driver incapacity is directly detected based on these vital signs, facial expressions, and limb movements, an emergency event is confirmed.

[0034] If no emergency event is detected during step S1, then step S2 is triggered. Specifically, the electronic control unit can access the window control buttons located on the doors or other parts of the vehicle. These buttons can be pressed by the driver or other occupants to generate window raising / lowering commands. For example, if the driver wants to raise the window, they can press one side of the window control button, triggering the electronic control unit to generate a command to raise the window; if the driver wants to lower the window, they can press the other side of the button, triggering the command to lower the window; if the driver wants to keep the window open, they can leave the window control button undone, in which case the electronic control unit will not generate a command.

[0035] If the electronic control unit generates a window lifting command in step S2, it sends the command to the window regulator in the door system, thereby executing step S3 and controlling the window regulator to raise or lower the window at a second lifting rate. In this embodiment, the second lifting rate is a rate that conforms to the commonly used window lifting rate. For example, since a commonly used window lifting rate is 100mm / s-200mm / s, the second lifting rate can be determined as a window lifting rate within the range of 100mm / s-200mm / s, such as 150mm / s.

[0036] In this embodiment, the effect of performing steps S2-S3 is as follows: Figure 5 As shown. (Refer to...) Figure 5 In the absence of an emergency, and without the driver operating the window control buttons to raise or lower the window, or even if the driver actively operates the window control buttons, the window remains at its original opening degree, or raises or lowers at a relatively small second raising / lowering rate as described in this embodiment. Thus, the power generation winding module within the window remains stationary relative to the magnet, or moves relative to the magnet at a relatively small second raising / lowering rate. The magnetic field generated by the magnet, passing through a portion of the power generation winding module, becomes a time-varying magnetic field relative to the power generation winding module, causing the power generation winding module to generate electricity. However, due to the small second raising / lowering rate, the rate of change of the time-varying magnetic field is small. The internal resistance of the transparent light-emitting element or the series resistor causes a voltage drop on the electromotive force generated by the power generation winding module, resulting in the transparent light-emitting element in the window not emitting light or having very low brightness. The window remains transparent and can be used normally.

[0037] If an emergency event is detected during step S1, then step S4 is triggered. Specifically, the electronic control unit generates a window lifting command indicating that the window glass is repeatedly raised and lowered at a first lifting rate, and sends the window lifting command to the window regulator, thereby controlling the window regulator to drive the window glass to repeatedly raise and lower at the first lifting rate.

[0038] In this embodiment, the first lifting rate can be set to twice or more than the second lifting rate. Thus, the car window, driven by the window regulator, rises at a relatively high first lifting rate, then falls at a relatively high first lifting rate, then rises again at a relatively high first lifting rate, then falls again at a relatively high first lifting rate… and so on, in a continuous cycle.

[0039] In this embodiment, the effect of performing step S4 is as follows: Figure 6 As shown. (Refer to...) Figure 6 In the event of an emergency, even if the driver becomes incapacitated, the repeated raising and lowering of the window at a relatively high initial rate causes the power generation winding module within the window to move relative to the magnet at a relatively high initial rate. The magnetic field generated by the magnet, passing through a portion of the power generation winding module, becomes a time-varying magnetic field, causing the power generation winding module to generate electricity. Moreover, due to the high initial rate of raising and lowering, the rate of change of the time-varying magnetic field is also high. The electromotive force generated by the power generation winding module, after passing through the internal resistance of the transparent light-emitting body or the voltage drop of the series resistor, is sufficient to drive the transparent light-emitting body in the window to emit light, thus creating a luminous graphic with the shape of the first character on the window. On one hand, the first character displayed by the luminous transparent light-emitting body is enough to attract the attention of people outside the vehicle, thereby increasing the possibility of rescue for occupants in an emergency. On the other hand, the repeated raising and lowering of the window at the initial rate of raising and lowering also attracts the attention of people outside the vehicle, further increasing the possibility of rescue for occupants in an emergency.

[0040] Therefore, the window glass, door system, and control method in this embodiment can, when a car encounters an emergency that causes the driver or other occupants to become incapacitated or in other dangerous situations, control the raising and lowering of the window glass to make the transparent light-emitting element in the window glass emit light, thereby attracting the attention of people outside the car and increasing the possibility of rescue for occupants in an emergency. When the car does not encounter an emergency, the window glass can remain transparent, allowing the window glass to be used normally. Therefore, the window glass, door system, and control method in this embodiment can effectively protect the safety of life and property during the use of a car.

[0041] In this embodiment, a car equipped with windows and door systems can achieve the same technical effects as a car with windows and door systems.

[0042] A computer program that executes the control method of the door system in this embodiment can be written into a computer device or storage medium. When the computer program is read out and run, the control method of the door system in this embodiment is executed, thereby achieving the same technical effect as the control method of the door system in the embodiment.
