Description
Technical field
The utility model relates to auto electric accessory technical field, specifically, relates to a kind of switch indicating circuit of vehicle hazard alarm lamp.
Background technology
In order to make the parts such as the electric switch button of automobile, rear overall appearance (face is poor) is more harmonious attractive in appearance before operation, switch many employings self-replaced type of present vehicle hazard alarm lamp, so bring a problem, namely after switch presses down, Driver Vision is not known whether this switching manipulation be effective, whether now just need an indicator lamp to carry out surface switches effectively to be connected, indicator lamp glimmers with the frequency identical with outside steering indicating light simultaneously, and warning function can be more obvious.
Prior art is generally realized by following three kinds of modes:
One, uses the independent I/O mouth of flasher relay (Input/Output, input/output port) to drive the switch indication light of danger alarm lamp, as shown in Figure 1.The application vehicle of this kind of scheme must have flasher relay, and in addition, switch indication light needs to take separately flasher relay I/O mouth, and in today that vehicle electronics electrical equipment control is integrated, integrated level not higher position means waste.
Its two, use BCM(Body Control Module, Body control module) separately I/O mouth drive the switch indication light of danger alarm lamp, as shown in Figure 2.Due to the develop rapidly of current automotive electronic technology, vehicle electronics electrical control is toward the future development of Highgrade integration, and the integrated level of existing BCM is very high, and I/O mouth resource is of great rarity, and this kind of scheme takies separately BCM I/O mouth and just seem and comparatively waste.
Its three, adopt the left and right turn lamp driving power source that BCM exports simultaneously, in the switch internal design AND circuit of danger alarm lamp, and then driving switch indicator lamp, as shown in Figure 3.This kind of scheme, owing to adding AND circuit electronic devices and components, make the switch internal circuit of hydropac lamp comparatively complicated, and device cost is also higher.
Utility model content
For overcoming the problems referred to above of the prior art, the switch indicating circuit of the vehicle hazard alarm lamp that the utility model provides a kind of structure simple, reasonable in design, with low cost.
To achieve these goals, the technical solution adopted in the utility model is as follows:
A kind of switch indicating circuit of vehicle hazard alarm lamp, comprise Body control module BCM, the left steering lamp DL be connected with the I/O mouth of Body control module BCM respectively and right steering lamp DR, wherein Body control module BCM accesses power supply driving power, the I/O mouth of described Body control module BCM is also connected with on-off signal branch road, this on-off signal branch road is also connected with the indicator lamp branch road with left steering lamp DL or right steering lamp DR common drive power supply; This on-off signal branch road comprise two-way gang switch K, resistance R1 and or door OR, wherein two-way gang switch K is in parallel with resistance R1, and one end series connection or door OR, the other end is connected with the I/O mouth of Body control module BCM.Described on-off signal branch road and indicator lamp branch road are all arranged in the shift knob of vehicle hazard alarm lamp.
Further, described two-way gang switch K comprises K switch 1 and the K switch 2 of interlock mutually, and wherein, K switch 1 is in parallel with resistance R1.
Particularly, described indicator lamp branch road comprises the K switch 2, resistance R2 and the indicator lamp LED that connect successively, and wherein K switch 2 also accesses the driving power of left steering lamp DL or right steering lamp DR.
As preferably, described two-way gang switch K is micro-switch.
Compared with prior art, the utility model has following beneficial effect:
The utility model is skillfully constructed, two-way gang switch is adopted in the switch of danger alarm lamp, make the on-off signal of one road output alarm lamp, the driving power break-make of another way control switch indicator lamp, ensure that the connection realizing indicator lamp driving power while switch output signal, simultaneously by the driving circuit of the driving power of indicator lamp branch road access left or right steering indicating light, make it common drive power supply, avoid the I/O mouth of indicator lamp branch road to BCM to take separately, save the I/O mouth resource of BCM preciousness, improve the integrated level of vehicle electronics electrical control, also ensure that the conformability of indicator lamp flicker frequency and steering indicating light flicker frequency, and its structure is simple, with low cost, be with a wide range of applications, be applicable to applying.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail, and embodiment of the present utility model includes but not limited to the following example.
Embodiment
As shown in Figure 4 and Figure 5, the switch indicating circuit of this vehicle hazard alarm lamp, comprise Body control module BCM, the left steering lamp DL be connected with the I/O mouth of Body control module BCM respectively and right steering lamp DR, wherein Body control module BCM accesses power supply driving power, also comprises on-off signal branch road and indicator lamp branch road.Described on-off signal branch road comprise K switch 1, resistance R1 and or door OR, wherein, K switch 1 is in parallel with resistance R1, and one end series connection or door OR, the other end is connected with the I/O mouth of Body control module BCM.Described indicator lamp branch road comprises the K switch 2, resistance R2 and the indicator lamp LED that connect successively, and wherein, K switch 2 accesses the driving power of left steering lamp DL, and as shown in Figure 4, or K switch 2 accesses the driving power of right steering lamp DR, as shown in Figure 5.Further, K switch 1 and K switch 2 link mutually, common formation two-way gang switch K, its preferred micro-switch.
