Description
Technical field
The utility model is technical field of automotive electronics, is specifically related to a kind of automobile one key and starts main frame.
Background technology
Its power supply part of ignition system traditional is on the market all contacts, and when work switches, contact point can produce spark, affects the life-span of power supply part, and reliable operation sexual needs are strengthened further.
Summary of the invention
For the deficiency that existing product exists, the utility model object is to provide automobile one key that a kind of reliability of service is higher to start main frame.
To achieve these goals, the utility model is achieved through the following technical solutions: a kind of automobile one key starts main frame, it is characterized in that, comprise host housing, main frame pcb board, main frame drain pan and screw, main frame pcb board is arranged between host housing and main frame drain pan, and connect into an entirety by screw, described main frame pcb board is welded with ON to power metal-oxide-semiconductor, ACC powers metal-oxide-semiconductor, starting relay, described ON metal-oxide-semiconductor of powering is composed in parallel by four metal-oxide-semiconductors, described ACC metal-oxide-semiconductor of powering is composed in parallel by two metal-oxide-semiconductors, described starting relay is composed in parallel by two relays, starting relay open contact connects startup mouth simultaneously, normally closed contact connects ON mouth.
The utility model has following beneficial effect:
(1), power supply part adopts metal-oxide-semiconductor to power, and mode belongs to system without deaerator, the loss of mechanical contact, can not produce spark, improves service life of power supply part;
(2), activation member composes in parallel by two relays, even if there is a relay damaged, circuit also can normally work, and improves host work reliability.
Accompanying drawing explanation
The utility model is described in detail below in conjunction with the drawings and specific embodiments
Fig. 1 is structural representation of the present utility model
Detailed description of the invention
The technological means realized for making the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with detailed description of the invention, setting forth the utility model further.
With reference to Fig. 1, this detailed description of the invention is by the following technical solutions: a kind of automobile one key starts main frame, it is characterized in that, comprise host housing (1), main frame pcb board (2), main frame drain pan (3), screw (7), main frame pcb board (2) is fixed between host housing (1) and main frame drain pan (3), and connect into an entirety with screw (7), described main frame pcb board (2) is welded with ON to power metal-oxide-semiconductor (4), ACC powers metal-oxide-semiconductor (5), starting relay (6), described ON metal-oxide-semiconductor (4) of powering composes in parallel control by four metal-oxide-semiconductors, described ACC metal-oxide-semiconductor (5) of powering composes in parallel control by two metal-oxide-semiconductors, described starting relay (6) is composed in parallel by two relays, starting relay (6) open contact connects startup mouth simultaneously, normally closed contact connects ON mouth.
This specific implementation process: when main frame does not detect actv. brake signal and oil circuit signal, when main frame first time detects that starting button presses, 2 ACC power metal-oxide-semiconductor conducting simultaneously, for car ACC subsequent conditioning circuit is powered; When main frame second time detects that starting button presses, 4 ON power metal-oxide-semiconductor conducting simultaneously, for car ON subsequent conditioning circuit is powered; When main frame third time detects that starting button presses, closedown ACC and ON powers by main frame; When main frame detects that starting button presses again, start the number of times of button carry out that ACC powers, ON powers, close ACC and ON powered operation respectively according to pressing again, circulate so successively.When Host Detection is to actv. brake signal and oil circuit signal, when main frame first time detects that starting button presses, 2 ACC power metal-oxide-semiconductor conducting simultaneously, for car ACC subsequent conditioning circuit is powered; When main frame second time detects that starting button presses, 4 ON power metal-oxide-semiconductor conducting simultaneously, for car ON subsequent conditioning circuit is powered; When main frame third time detects that starting button presses, main frame performs ignition operation, now closedown ACC powers and ON exports, two starting relays action simultaneously parallel connection performs igniting and exports by main frame, after execution igniting exports, stop again starting relay action to recover ACC simultaneously and power and ON output.When main frame detects that starting button presses for the 4th time, main frame will perform quenching operations, close ACC and ON and power; When main frame detects that starting button presses again, start the number of times of button carry out that ACC powers, ON powers, perform ignition operation, perform quenching operations respectively according to pressing again, circulate so successively.Perform ACC and the ON process of powering at main frame, employing be system without deaerator mode, the loss of mechanical contact, does not produce contact sparking, improves service life and the reliability of related components; Main frame is in the process performing ignition operation, and two starting relay action simultaneously parallel connections are carried out igniting and exported, even if there is relay damaged circuit also can normally work, improve the reliability of product work.
More than show and describe groundwork of the present utility model and principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
