Description

Compound locomotive parking light control module

The invention relates to a composite locomotive parking lamp control module. The parking lamp control module is connected in parallel with the locomotive directional lamp control circuit, and can realize the functions of electric power output and parking warning by using the original power supply and the directional light of the locomotive.

The general locomotive direction light control circuit includes a directional light switch connected to the power source and a flasher. When the directional light switch is switched to the right side, the right direction directional light flashes by starting the flasher, so that other occupants can know the locomotive. Prepare to turn right; for the same reason, if the direction light switch is switched to the left side, the left direction light will flash.

In addition to the left and right switching blinking as a direction indication, the locomotive direction light has added a parking warning function in the prior art. In short, when the parking light switch is turned on, all the directional lights can be flashed at the same time through the flasher, or In addition, the parking warning circuit drives all the direction lights to flash the warning, so when the user stops the locomotive, it can warn other passers-by to avoid danger when the night light is insufficient; similarly, if the locomotive runs at night When there is insufficient lighting, heavy rain causes the sight to be unclear, or the road is upside down, you can also use the parking to warn other passers-by.

Although the above-mentioned locomotive direction light can be combined with the direction indication and the parking warning function by adding a parking light switch, the control of the two functions in practice may be in conflict under certain conditions. For example, when the parking light switch is turned on and all the directional lights are blinking at the same time, if the locomotive is preparing to turn right and the directional light switch is switched to the right side, at this time, since all the directional lights are blinking at the same time, the directional light cannot be Right-turning instructions, other passers-by can’t predict that the locomotive is preparing for the right turn.

In addition, with the extensive use of electronic products such as smart phones, setting up USB charging on the locomotive is also the direction of R&D and design of the new generation of locomotives.

(2) The above-mentioned electric door switch and the parking light switch are turned on, so that the left and right direction lights are simultaneously blinking, and if the locomotive is in a running state, and the directional light control circuit is started due to the need to turn left or right, the directional light control circuit outputs left and right. One of the terminals outputs a signal to the control unit through the corresponding two-way transmission end, so that the control unit stops the parking warning, and the left or right direction light can operate the left or right direction light according to the original setting of the locomotive. Perform the direction indication function to avoid the directional light failure when the parking warning light is blinking.

(3) When the switch is turned on, the parking light switch is turned off, and the locomotive is in normal running state, the control unit obtains the vehicle speed signal from the second input terminal. At this time, if the vehicle speed signal indicates that the vehicle speed drops sharply, for example, the vehicle speed is running normally. Suddenly falling from 60km/hr to 20km/hr in 1 second, or using gravity acceleration sensor to sense gravity acceleration, indicating that an emergency may be encountered in an emergency. At this time, the control unit can pass the third input.

Electrically connected, the directional light control circuit 200 has left and right output ends 202, 203 electrically connected to the left and right direction lamp input ends 402, 403 of the left and right direction lights 420, 430, respectively. When the switch 100 is turned on, the switch input 301 is powered by the battery 500, and is output to the directional light control circuit input terminal 201 through the switch output 302, so that when the locomotive is in the normal running state, the directional light control circuit 200 is activated. When one of the left and right output terminals 202, 203 is turned on, the left direction light 420 or the right direction light 430 can be blinked by the left and right direction light input ends 402, 403; the direction light control circuit 200 is provided with a flash that controls the blinking frequency. This is a general technique and will not be described here.

The present invention relates to a composite locomotive parking lamp control module 100 comprising: a USB controller 10, and a control unit 30 electrically connected to the parking light switch 20, wherein:

The USB controller 10 has a power input terminal 11 electrically connected to the output of the circuit switch 302, and has a USB output port 12 capable of outputting power. When the switch 300 is turned on, it is powered by the switch output 302. USB output 埠12; The USB output 埠12 is set outside the locomotive for the convenience of the locomotive rider, and may be short-circuited due to rain or moisture. Therefore, the USB controller 10 can be controlled by the control unit 30 and short-circuited to the USB output 埠12. The power supply is stopped until the short circuit is removed.

The parking light switch 20 has a parking light switch input end 21 electrically connected to the electric door switch output end 302, and a parking light switch output end 22 capable of outputting a parking signal. When the electric door switch 300 is turned on and the parking light switch 20 is turned on The parking signal can be output from the parking light switch output 22 to the control unit 30.

The control unit 30 includes: a first input end 31 electrically connected to the parking light switch output end 22, a second input end 32 connected to the vehicle speed signal 321, a third input end 33 electrically connected to the electric door switch input end 301, and The two bidirectional transmission ends 342, 343 are electrically connected between the left and right output ends 202, 203 of the direction light control circuit 200 and the left and right direction lamp input ends 402, 403; the third input end 33 is electrically connected to the electric door switch input end 301, The power can be obtained independently from the battery 500. In implementation, the vehicle speed signal 321 is provided by an original vehicle speed detecting unit on a locomotive or by a gravity accelerometer (G Sensor) built in the control unit (not shown).

As shown in the second figure, when the electric door switch 300 is turned on, the locomotive only needs to turn on the parking light switch 20, whether it is in the running state, or the idle state or the flameout state, and can sequentially pass the electric door switch output end 302 and park. The light switch 20, the first input end 31 of the control unit 30, the two bidirectional transmission ends 342, 343, and the left and right direction lamp input ends 402, 403 cause the left and right direction lights 420, 430 to flash simultaneously to achieve the parking warning function. The parking warning function also includes road conditions during driving Warnings such as subtlety, lack of nighttime lighting, heavy rain or fogging make the line of sight unclear.

As shown in the third figure, the above-mentioned electric door switch 300 and the parking light switch 20 are turned on, so that the left and right direction lights 420, 430 are simultaneously blinking, if the locomotive is in a running state, and the left or right turn is required to start the directional light control circuit. 200, when one of the left and right direction lights 420, 430 is flashed to indicate the direction, the left and right output ends 202, 203 of the direction light control circuit 200 output a signal to the control unit 30 through the corresponding one of the two-way transmission ends 342, 343, The control unit 30 stops the parking warning.
