DETAILED DESCRIPTION
The technical solutions in the embodiments of the present application will be described clearly and completely hereinafter in conjunction with the drawings in the embodiments of the present application. Apparently, the described embodiments are only one part of the embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all of other embodiments, made by those skilled in the art without any creative efforts, fall into the scope of the present application.
A control device for a power window switch is provided according to the present application, and a structure thereof is shown in Figure 1. The control device for the power window switch includes:
an infrared transmitting device 11, an infrared receiving device 12, a control device 13 connected to the infrared receiving device 12, and a structural member 14 arranged between the infrared transmitting device 11 and the infrared receiving device 12.
The infrared receiving device 12 may include a first infrared receiving unit 121 and a second infrared receiving unit 122.
The infrared transmitting device 11 is configured to transmit infrared signals, and the infrared transmitting device 11 may be configured to transmit an infrared signal in real time or at a fixed interval of time, and may also be configured to start transmitting an infrared signal when the control device for the power window switch receives an operation instruction sent by a user.
The structural member 14 receives the operation instruction of the user, and moves according to the operation instruction of the user, to control whether the first infrared receiving unit 121 and the second infrared receiving unit 122 are allowed to receive the infrared signals transmitted by the infrared transmitting device 11 or not.
That is, the user sends different operation instructions, and the operation instructions are recognized by the recognition unit as different electric signals, thus controlling the raising and lowering of a power window glass.
Specifically, the operation instructions may include a manual raising operation instruction, a quick automatic raising operation instruction, a manual lowering operation  instruction, and a quick automatic lowering operation instruction, etc. . The final positions of the structural member 14 include an initial position, a position corresponding to the manual raising operation, a position corresponding to the quick automatic raising operation, a position corresponding to the manual lowering operation, and a position corresponding to the quick automatic lowering operation etc..
The structural member 14 may specifically be of a U-shaped structure, and the first infrared receiving unit 121 and the second infrared receiving unit 122 are arranged at an empty position between two side walls of the U-shaped structure. In such a case, the U-shaped structure is in the initial position, and it is not difficult for the U-shaped structure to block the infrared signals transmitted by the infrared transmitting device 11 to the infrared receiving device 12. The two side walls of the U-shaped structure are respectively configured to block the infrared signal transmitted by the infrared transmitting device 11 to the infrared receiving device 12 when the U-shaped structure moves.
The first infrared receiving unit 121 and the second infrared receiving unit 122 respectively output a level signal according to the movement of the structural member.
In the case that the structural member moves to a position which does not allow the first infrared receiving unit 121 to receive the infrared signal transmitted by the infrared transmitting device 11, the first infrared receiving unit 121 outputs a high-level signal. In the case that the structural member moves to a position which allows the first infrared receiving unit 121 to receive the infrared signal transmitted by the infrared transmitting device 11, the first infrared receiving unit 121 outputs a low-level signal.
In the case that the structural member moves to a position which does not allow the second infrared receiving unit 122 to receive the infrared signal transmitted by the infrared transmitting device 11, the second infrared receiving unit 122 outputs a high-level signal. In the case that the structural member moves to a position which allows the second infrared receiving unit 122 to receive the infrared signal transmitted by the infrared transmitting device 11, the second infrared receiving unit 122 outputs a low-level signal.
The infrared transmitting device 11 and the infrared receiving device 12 together constitute an infrared sensor configured to detect a level signal. That is, when the user outputs an operation instruction to cause the level signal to change, the control device 13 is allowed to receive level signals at various stages, namely, the level signals changing from moment to  moment.
The control device 13 receives the level signal, and generates a control instruction according to changes of the level signal during the movement of the structural member 14, to control the raising and lowering of the power window glass.
Since the structural member 14 is configured to change from the initial position to the position corresponding to the manual raising operation, the position corresponding to the quick automatic raising operation, the position corresponding to the manual lowering operation, or the position corresponding to the quick automatic lowering operation, during the above position changes of the structural member 14, the level signals transmitted by the infrared receiving device and received by the control device 13 change along with the position changes of the structural member, i.e., the level signals received by the control device 13 follows a change law, and a final control instruction is determined by the change law.
Specifically, a generation law for the control instruction is preset, that is, when the change law of the level signal is a first law, a first control instruction is generated, i.e., a manual lowering instruction. When the change law of the level signal is a second law, a second control instruction is generated, i.e., a quick automatic lowering instruction. When the change law of the level signal is a third law, a third control instruction is generated, i.e., an automatic raising instruction. When the change law of the level signals is a fourth law, a fourth control instruction is generated, i.e., a quick automatic raising instruction.
The control device for the power window switch according to this embodiment includes the infrared transmitting device, the infrared receiving device, the control device, and the structural member which is arranged between the infrared transmitting device and the infrared receiving device, and configured to block the infrared signal transmitted by the infrared transmitting device. The infrared receiving device includes the first infrared receiving unit and the second infrared receiving unit, and the first infrared receiving unit and the second infrared receiving unit are controlled by the movement of the structural member according to the operation instruction of the user, to receive or not receive the infrared signal, thus outputting different level signals. The control device controls the raising and lowering of the power window glass according to the changes of the level signal during the movement of the structural member. In this technical solution, the infrared receiving device transmits different level signals when the infrared receiving device is allowed to receive the infrared signal or not  allowed to receive the infrared signal, so as to realize recognition for the operation instructions of the user, thereby controlling the power window switch, thus avoiding a direct contact between the contact points, reducing the physical abrasion, and improving a service life of the control system.
A control device for a power window switch is provided according to another embodiment, the structure of which is shown in Figure 2. The control device for the power window switch includes an infrared transmitting device 21, an infrared receiving device 22, a control device 23 connected to the infrared receiving device 22, and a structural member 24 arranged between the infrared transmitting device 21 and the infrared receiving device 22. The infrared transmitting device 21 includes a first infrared transmitting unit 211 and a second infrared transmitting unit 212, and the infrared receiving device 22 includes a first infrared receiving unit 221 and a second infrared receiving unit 222.
In addition to the same structures as the control device according to the above embodiment, the first infrared transmitting unit 211 and the second infrared transmitting unit 212 are further provided according to this embodiment.
The first infrared transmitting unit 211 transmits an infrared signal to the first infrared receiving unit 221, and the second infrared transmitting unit 212 transmits an infrared signal to the second infrared receiving unit 222.
That is, the first infrared receiving unit 221 only receives the infrared signal transmitted by the first infrared transmitting unit 211, and the second infrared receiving unit 222 only receives the infrared signal transmitted by the second infrared transmitting unit 212.
In the case that the structural member 24 is of a U-shaped structure, the moving of the U-shaped structure may be implemented in the following ways: the U-shaped structure moves parallelly, i.e., two side walls of the U-shaped structure vertically block the infrared signal transmitted by the infrared transmitting device to the infrared receiving device. And the U-shaped structure may also swing about a center point, and the center point is a fixed point on the U-shaped structure.
The center point being a point at a center position of the body of the U-shaped structure is taken as an example.
As shown in Figure 3, which is a schematic view showing the structural member 24  in the initial position, supposed that the two side walls of the structural member 24 are respectively indicated by A and B, and a middle empty area between the two side walls of the structural member 24 is indicated by O.
In the case that the structural member 24 is located at the initial position, the first infrared receiving unit 221 and the second infrared receiving unit 222 are located at the middle empty area O between the two side walls of the structural member 24, and are not blocked by the two side walls of the structural member 24. No matter how the structural member 24 moves or swings, the physical positions of the first infrared receiving unit 221 and the second infrared receiving unit 222 are not changed, however, the relative positions of the first infrared receiving unit 221 and the second infrared receiving unit 222 with respect to the middle empty area O between the two side walls of the structural member 24 are changed.
In the case that the operation instruction sent by the user is the manual lowering operation instruction, i.e., in the case that the power window switch is adjusted to be in a manual lowering tap position, the structural member 24 swings from the initial position to the position corresponding to the manual lowering operation, and the position of the structural member 24 in this case is shown in Figure 4.
The side wall B of the structural member 24 may block the infrared signal transmitted by the first infrared transmitting device 211 to the first infrared receiving unit 221. At this moment, the first infrared receiving device 221 transmits a high-level signal, and the second infrared receiving device 222 transmits a low-level signal. In the case that the power window switch returns to the initial position from the manual lowering tap position, the side wall B of the structural member 24 may not block the infrared signal transmitted by the first infrared transmitting device 211 to the first infrared receiving device 221, and also may not block the infrared signal transmitted by the second infrared transmitting device 212 to the second infrared receiving device 222. At this moment, the first infrared receiving device 221 transmits a low-level signal, and the second infrared receiving device 222 transmits a low-level signal.
Thus, in the case that the operation instruction sent by the user is the manual lowering operation instruction, the change process of the level signals transmitted by the first infrared receiving device 221 is from the low-level signal, to the high-level signal, and then the to low-level signal； and the change process of the level signals transmitted by the second  infrared receiving device 222 is from the low-level signal, to the low-level signal, and then to the low-level signal.
Therefore, the control instruction transmitted by the control device 23 is the manual lowering instruction in the case that the change process of the level signal transmitted by the first infrared receiving device 221 is from the low-level signal, to the high-level signal, and then to the low-level signal, and the change process of level signal transmitted by the second infrared receiving device 222 is from the low-level signal, to the low-level signal, and then to the low-level signal.
In the case that the operation instruction sent by the user is the quick automatic lowering operation instruction, i.e., in the case that the power window switch is adjusted to be in a quick automatic lowering tap position, the structural member 24 swings from the position corresponding to the manual lowering operation to the position corresponding to the quick automatic lowering operation, and the position of the structural member 24 in this case is shown in Figure 5.
The side wall B of the structural member 24 may block the infrared signal transmitted by the first infrared transmitting device 211 to the first infrared receiving device 221, and infrared signal transmitted by the second infrared transmitting device 212 to the second infrared receiving device 222. At this moment, the first infrared receiving device 221 transmits a high-level signal, and the second infrared receiving device 222 transmits a high-level signal. In the case that the power window switch returns to the manual lowering tap position from the quick automatic lowering tap position, the side wall B of the structural member 24 may block the infrared signal transmitted by the first infrared transmitting device 211 to the first infrared receiving device 221. At this moment, the first infrared receiving device 221 transmits a high-level signal, and the second infrared receiving device 222 transmits a low-level signal.
Thus, in the case that the operation instruction sent by the user is the quick automatic lowering operation instruction, the change process of level signals transmitted by the first infrared receiving device 221 is: from a high-level signal, to a high-level signal and then to a high-level signal； and the change process of level signals transmitted by the second infrared receiving device 222 is: from a low-level signal, to a high-level signal and then to a low-level signal.
Therefore, the control instruction transmitted by the control device 23 is the quick automatic lowering instruction in the case that the change process of the level signals transmitted by the first infrared receiving device 221 is from a high-level signal, to a high-level signal, and then to a high-level signal, and the change process of level signals transmitted by the second infrared receiving device 222 is from a low-level signal, to a high-level signal, and then to a low-level signal.
In the case that the operation instruction sent by the user is the manual raising operation instruction, i.e., in the case that the power window switch is adjusted to be in a manual raising tap position, the structural member 24 swings from the initial position to the position corresponding to the manual raising operation, and the position of the structural member 24 in this case is shown in Figure 6.
The side wall A of the structural member 24 may block infrared signal transmitted by the second infrared transmitting device 212 to the second infrared receiving device 222. At this moment, the second infrared receiving device 222 transmits a high-level signal, and the first infrared receiving device 221 transmits a low-level signal. In the case that the power window switch returns to the initial position from the manual raising tap position, the side wall A of the structural member 24 may not block infrared signal transmitted by the first infrared transmitting device 211 to the first infrared receiving device 221, and also may not block infrared signal transmitted by the second infrared transmitting device 212 to the second infrared receiving device 222. At this moment, the first infrared receiving device 221 transmits a low-level signal, and the second infrared receiving device 222 transmits a low-level signal.
Thus, in the case that the operation instruction sent by the user is the manual raising operation instruction, the change process of level signals transmitted by the first infrared receiving device 221 is: from a low-level signal, to a low-level signal, and then to a low-level signal； and the change process of level signals transmitted by the second infrared receiving device 222 is: from a low-level signal, to a high-level signal, and then to a low-level signal.
Therefore, in the case that the change process of level signals transmitted by the first infrared receiving device 221 is from a low-level signal, to a low-level signal, and then to a low-level signal, and the change process of level signals transmitted by the second infrared receiving device 222 is from a low-level signal, to a high-level signal, and then to a low-level  signal, the control instruction transmitted by the control device 23 is the manual raising instruction.
In the case that the operation instruction sent by the user is the quick automatic raising operation instruction, i.e., in the case that the power window switch is adjusted to be in a quick automatic raising tap position, the structural member 24 swings from the position corresponding to the manual raising operation to the position corresponding to the quick automatic raising operation, and the position of the structural member 24 in this case is shown in Figure 7.
The side wall A of the structural member 24 may block the infrared signal transmitted by the first infrared transmitting device 211 to the first infrared receiving device 221, and the infrared signal transmitted by the second infrared transmitting device 212 to the second infrared receiving device 222. At this moment, the first infrared receiving device 221 transmits a high-level signal, and the second infrared receiving device 222 transmits a high-level signal. In the case that the power window switch returns to the manual raising tap position from the quick automatic raising tap position, the side wall A of the structural member 24 may block the infrared signal transmitted by the second infrared transmitting device 212 to the second infrared receiving device 222. At this moment, the first infrared receiving device 221 transmits a low-level signal, and the second infrared receiving device 222 transmits a high-level signal.
Thus, in the case that the operation instruction sent by the user is the quick automatic raising operation instruction, the change process of level signals transmitted by the first infrared receiving device 221 is: from a low-level signal, to a high-level signal and then to a low-level signal； and the change process of level signals transmitted by the second infrared receiving device 222 is: from a high-level signal, to a high-level signal, and then to a high-level signal.
Therefore, the control instruction transmitted by the control device 23 is the quick automatic raising instruction in the case that the change process of level signals transmitted by the first infrared receiving device 221 is from a low-level signal, to a high-level signal and then to a low-level signal, and the change process of level signals transmitted by the second infrared receiving device 222 is from a high-level signal, to a high-level signal, and then to a high-level signal.
Generally, the quick lowering position can be reached starting from the initial shift position and passing through the manual lowering position, and the quick raising position can be reached by starting from the initial position and passing through the manual raising position. Thus, the level signal transmitted when the structural member is at the position corresponding to the quick lowering operation can be realized only after realizing the level signal transmitted when the structural member is at the position corresponding to the manual lowering operation, and the level signal transmitted when the structural member is at the position corresponding to the quick raising operation can only be realized only after realizing the level signal transmitted when the structural member is at the position corresponding to the manual raising operation.
The control device for the power window switch according to this embodiment includes the infrared transmitting device, the infrared receiving device, the control device, and the structural member, which is arranged between the infrared transmitting device and the infrared receiving device, and configured to block the infrared signals transmitted by the infrared transmitting device. The infrared receiving device includes the first infrared receiving unit and the second infrared receiving unit. The structural member moves according to the operation instruction of the user, to control the first infrared receiving unit and the second infrared receiving unit to receive or not to receive the infrared signal, thus outputting different level signals. The control device controls the power window switch according to the changes of the level signal during the movement of the structural member. In this solution, the infrared receiving device transmits different level signals when the infrared receiving device is allowed or not allowed to receive the infrared signal, to achieve the recognition to the operation instruction of the user, thereby realizing controlling to the power window switch, thus avoiding the direct contact between the contact points, reducing the physical abrasion, and improving a service life of the control system.
The above embodiments are described in a progressive manner. Each of the embodiments is mainly focused on describing its differences from other embodiments, and references may be made among these embodiments with respect to the same or similar portions among these embodiments. For the device according to the embodiments, the description of the device is simple since it corresponds to the method according to the embodiments, and for the related parts, references may be made to the illustration of the method embodiments with respect to the related parts.

The steps of the methods or algorithms described in conjunction with the embodiments of the present application can be implemented with hardware, software modules executed by a processor, or a combination of both. The software modules may reside in a random access memory, an internal memory, a read only memory, an electrically programmable read only memory, an electrically-erasable programmable read only memory, a register, a hard disk, a removable disk drive, compact disc read only memory, or any other types of storage media well known in the technical field.
The description of the embodiments herein enables those skilled in the art to implement or use the present application. Various modifications to the embodiments will be apparent to those skilled in the art, and the general principle herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application is not limited to the embodiments described herein, but should be in accordance with the widest scope consistent with the principle and novel features disclosed herein.
