Detailed Description
The invention is further described below by means of specific embodiments.
Example one
Referring to fig. 5, a window regulator control apparatus includes a plurality of switches 10, a control module 20, a plurality of lift modules 30, a voltage stabilizing module 50, and the like. Each switch 10 is used to control one lift module 30, typically four sets, for controlling a left front door window, a left rear door window, a right front door window and a right rear door window, respectively. But not limited to this, the number may also be adjusted according to actual requirements, for example, two groups, three groups, or six groups.
The switch 10 is provided with a sliding end 11, and a button can be installed on the sliding end 11 for convenient operation by controlling the sliding end 11 to slide to output a signal related to the displacement. Referring to fig. 3 and 7, the switch 10 may employ an electronic component such as a potentiometer or an encoder for converting a linear displacement into an electrical signal, and the output signal related to the displacement may be a voltage signal, a resistance value, a current signal, a pulse signal, or the like.
The switch 10 of the present invention is mounted to a housing 12, and the housing 12 is fixed to the inside of the door of the driver's seat and the inside of the other doors. Referring to fig. 1 and 2, the surface of the housing 12 is provided with one or more grooves 13, the grooves 13 are open at the top, and one or two switches 10 can be installed in one groove 13. The switch is located within the housing 12 and its slidable end can pass through and be slidably engaged with the bottom side or side wall of the recess.
Furthermore, an inclined surface 14 may be disposed on one side wall of the groove 13, and a sliding groove 15 is disposed on the inclined surface 14. The switch 10 is mounted in the housing 12 with its sliding end 11 passing through and in sliding engagement with the sliding slot 15 of the ramp 14.
The lifting module 30 is used for driving a corresponding vehicle window to ascend or descend, and may adopt a common structure in the prior art, such as a window regulator, including an arm-type window regulator, a single-arm-type window regulator, a double-arm-type window regulator, a rope-wheel-type window regulator, a cross-arm-type window regulator, a flexible window regulator, and the like.
Take a rope wheel type glass lifter as an example, which comprises a motor, a speed reducer, a guide rope, a guide plate, a glass mounting bracket and the like. During installation, the car window is fixed on the glass installation bracket, and the glass guide groove is parallel to the steel wire rope guide plate. The motor is started, the reducer is driven by the motor to output power, the steel wire rope is pulled to move the glass mounting bracket, and the door and window glass is forced to do ascending or descending linear motion.
The control module 20 is connected to the switches 10 and the lifting modules 30, and is configured to convert the signals related to the displacement into a lifting command, and the lifting command is used to control the motor to operate to drive the window to ascend or descend, and is configured such that the window displacement is proportional to the displacement of the sliding end 11. The control module 20 can adjust the sensitivity through algorithms.
The moving speed of the car window can be set to be linear change or exponential change according to requirements, wherein the linear change means that the displacement of the car window is changed in equal proportion, namely the car window moves at a constant speed; the exponential change means that the change of the window displacement moves slowly in the first half and moves quickly in the second half, namely, the variable speed movement.
Furthermore, the invention can also set the window lifting time according to the requirements, such as: the switch moves, and then the window moves along with the switch, or the window begins to move after the switch stops moving. The two modes can be selected or switched automatically. When the switch corresponds to the position of the car window, the switch and the car window move synchronously; when the switch position does not correspond to the window position (for example, the switch position is moved when the window power supply is turned off, or the window is controlled to move by another switch because the window switch is double-controlled), the window starts to move after the switch is stopped.
The control module can adjust the reaction time and the moving distance precision, and the operation rule is not limited to the above, and other better operation rules can be set again.
Preferably, the control module 20 and the lifting module 30 of the present invention are connected and communicated through a bus transceiver 80, but not limited thereto, the voltage stabilizing module 50 is connected to the vehicle power supply and control module 20 for ensuring the supply voltage is stable.
The position detection module 40 is further included, and may be a displacement sensor or a hall sensor, for example, which may detect the rotation speed of the motor through the hall sensor, and further detect the position of the window. The position detection module 40 is connected to the control module 20 to control the operation of the lift module 30 to stop when the window is in position.
If the Hall sensor is adopted, the number of turns of the motor is in direct proportion to the movement distance of the vehicle window in the moving process of the vehicle window, and the Hall sensor can generate a square wave pulse signal when the motor rotor rotates for a circle. When the vehicle window rises from the lowest position to the top, the pulse signals output by the hall sensors can be counted through the control module 20, the pulse signals are repeated up and down for several times from the lowest end to the highest end of the vehicle window, the average value is taken as a calibration reference, then the vehicle window starts to run from the lowest end position, the counting starts from zero, the rising process is performed with the counting according to the current counting value, and the falling process is performed with the counting according to the current counting value. Therefore, the current position of the vehicle window can be determined in real time through the pulse output and counting scheme of the Hall sensor.
The position of the window can be determined through current ripple detection of the motor, the running current of the driving end of the motor is converted into a voltage signal through the sampling resistor, the signal is compared with a reference voltage through isolation, filtering, amplification, shaping and the like to obtain a square wave signal corresponding to the position, and the number of square wave pulses is recorded through the control module 20 to obtain the position of the window and door.
In addition, the vehicle window can have an anti-pinch function, the anti-pinch function is prior to the switch, once the anti-pinch function is acted, the switch loses the action until the anti-pinch function stops working. The anti-pinch function can be realized by adopting the prior art.
In practical application, the specific circuit connection relationship of each module is as follows: referring to fig. 6, the control module 20 can be implemented by a single chip microcomputer S9S12G 128. Referring to fig. 8, 10, 12 and 14, the bus transceiver 80 may be a model TJA1024 corresponding to the number of the lifting modules 30, and includes a first bus transceiver, a second bus transceiver, a third bus transceiver and a fourth bus transceiver. Pins 55-61 of the control module 20 are operable to connect to the switch 10 and pins 78-81 are operable to connect to pins 8 of the first bus transceiver, the second bus transceiver, the third bus transceiver and the fourth bus transceiver, respectively. Pins 1 and 4 of the bus transceiver are connected to pins 92 and 93, respectively, of the control module 20.
The motors of the plurality of lifting modules 30, see fig. 9, 11, 13 and 15, are a first motor, a second motor, a third motor and a fourth motor, respectively, with pins 3, 4 connected to pins 7, 6 of the bus transceiver 80, respectively. The invention CAN select an Nimotion integrated closed-loop 42 stepping servo motor, the motor CAN carry out CAN bus control, has an absolute encoder, 14-bit resolution and control precision of 0.2 degree.
Referring to fig. 16 and 17, the first voltage stabilizing circuit and the second voltage stabilizing circuit of the voltage stabilizing module 50 of the present invention are respectively used for providing the working voltage VCC of 5V and 3.3V, so as to ensure that the corresponding modules operate normally.
The left front door window is taken as an example, the default window is in a closed state, and the working principle of the invention is as follows:
when the sliding end 11 of the control switch 10 moves to the middle position, the corresponding first switch PAD0 outputs a signal related to the displacement to the pin 55 of the control module 20, the control module 20 converts the signal related to the displacement into a lifting command, the lifting command is sent to the first bus transceiver, the first bus transceiver forwards the lifting command to the first motor, and the first motor operates according to the lifting command to drive the window to descend to the middle position and then stops operating.
Example two
A car window lifting control device is the same as the first embodiment in main structure, and is different from the first embodiment in that: and a touch switch is additionally arranged and is connected with the control module, and the touch switch is set to be pressed again within a certain time (such as one second) after the control switch slides, so that the lifting module can drive the car window to move, and the touch switch is ineffective after the specified time. Referring to fig. 18, the tact switch K is connected to a pin 63 of the control module, and this arrangement is used in order to prevent children from inadvertently clipping onto it to slide the switch. In addition, by pressing the tact switch for a long time, the tact switch function can be cancelled or turned on.
EXAMPLE III
Referring to fig. 4 and 19, a window lift control device has the same main structure as the first embodiment, except that: in order to increase the gear feeling of the switch 10, a plurality of teeth 16 are disposed on two opposite side walls of the sliding slot 15, and a gear slot is formed between two adjacent teeth 16. When the sliding end 11 of the operating switch 10 slides, the sliding end 11 of the switch 10 can be inserted into the gear slots, and the number of the gear slots can be set according to needs, including two, three, four, ten or more.
Further, a voice module 60 and a display module 70 are added, and the voice module 60 and the display module 70 are respectively connected with the control module 20. The number of the voice modules 60 can be one or correspond to the number of the vehicle windows, and the voice modules 60 are used for carrying out voice prompt on the displacement or gear position of the vehicle windows. The number of the display modules 70 is only one, and the display modules are installed at appropriate positions near the driver seat and used for displaying the current positions or gears of the windows.
The main working principle is also the same as that of the first embodiment, and the difference is that: when the window is lifted in place, the voice module 60 can broadcast the corresponding window position or gear information, and meanwhile, the display module 70 displays the position or gear information of each window.
Example four
Referring to fig. 20, a window lift control device has the same main structure as the first embodiment, except that: in order to increase the gear feeling of the switch 10, a plurality of teeth 16 are disposed on two opposite side walls of the sliding slot 15, a gear slot is formed between two adjacent teeth 16, and elastic members 17 are disposed at two ends of the inner wall of the sliding slot 15, wherein the elastic members 17 may be springs or elastic pieces. When the sliding end 11 of the operating switch 10 slides, the sliding end 11 of the switch 10 can be inserted into the gear slots, and the number of the gear slots can be set according to needs, including two, three, four, ten or more.
In this embodiment, it is set that the window is in a fully closed or fully open state when the sliding end is located in the region a-B. When the sliding end 11 is located at the left end B and the window is located at the middle position, if the window is to be closed, the compression elastic member 17 can be moved leftwards to be close to the position a, and after being released, the sliding end 11 rebounds for a short distance and stays at the point B, and the sliding process controls the window to move to the closed state. The problem that the operation of sliding back and forth is troublesome because the end is moved leftwards after moving a distance rightwards is avoided. When the sliding end 12 is at the right end of the sliding chute and the window is not closed, the operation principle of closing the window is the same.
