The utility model discloses an integrated pointing switch for vehicles the shell of which consists of a switch panel and an insulated shell. The switch panel is provided with a switch button and symbol display while the literal face of the insulated shell is fixed with an installing block button and the back is provided with a pencil of lines connecting connector. The self-reset switch button is the pointing switch with only a pair of normally open contacts. The controlling circuit is controlled by microcomputers. The emitting diode of the integrated pointing switch for vehicles of the utility model and a limiting current resistance are connected in series.
Description
(1) described technical field
The utility model belongs to the technical field of switch, the integrated point driving switch of particularly a kind of automobile.
(2) background technology
Present automotive department ignition distributor working method is controlled by the transforming gear of rocker switch.And the action form of rocker switch is multivariant, many gears, and electrical equipment in the course of the work, and the corresponding gear of rocker switch can not conversion, and is in running order always.Can be subjected to very big influence the useful life of rocker switch so; And the rocker switch of each function must be installed separately, makes it install and fix the hole and must repeat processing, and wire harness is pegged graft separately, is unfavorable for enhancing productivity; In addition, a rocker switch usually has several groups of contacts, the manufacturing process complexity, and cost is higher.
(3) summary of the invention
The utility model provides a kind of long service life in order to overcome the shortcoming of rocker switch, integrated point driving switch easy for installation.
The utility model is realized by following measure:
The utility model discloses the integrated point driving switch of a kind of automobile, its shell is made up of switch panel and insulation crust, shift knob and symbol are installed on the switch panel to be shown, the side of insulation crust is fixed with the installation buckle, the back is equipped with wire harness and connects connector, the microcomputer receiving inputted signal is by the corresponding electrical equipment action of corresponding program control; Shift knob is a point driving switch, has only a pair of normally opened contact, and shift knob is for resetting certainly.
The integrated point driving switch of automobile of the present utility model, symbol shows certain angle of inclination, and light source is the light-emitting diode that can send out different colours.
The integrated point driving switch of automobile of the present utility model is in series with current-limiting resistance on the light-emitting diode.
1. design principle:
1.1 along with Control Technique of Microcomputer large-scale application on automobile, the working forms of electrical equipment changes the software logic control mode into by control modes such as rocker switch, relays, behind the microcomputer control unit receiving key input signal, by the software control electricity consumption device of its establishment.In view of the foregoing, in conjunction with the automobile practical application, design a kind of integrated point driving switch, carry out the corresponding signal input, by respective logic software control corresponding electric appliance action, the integration mode of this crawl integrated switch determined by the rocker switch type of service on the present automobile, and its arrangement mode can horizontally-arranged, vertical setting of types, integrated quantity can be two or more, is in addition integrated according to the rocker switch behaviour in service of existing automobile in a word;
1.2 the signal of each point driving switch is directly sent into microcomputer, its working forms is a some dynamic formula, and the carrying out of one degree of freedom, the rated capacity of contact becomes the mA level by original A level.Can improve greatly the useful life of rocker switch so.
1.3 owing to adopt integrated, crawl, the design of mode such as altogether, significantly reduced the quantity with microcomputer interface, effectively utilize micro-processor controlled interface resource, existing interface is effectively utilized, and can realize expanding.
2. main design content and characteristics:
2.1 for the ease of installing and adapt to driver's operating habit, design a kind of integrated point driving switch, be installed under the situation that meets original rocker switch and arranged; Design the integrated point driving switch of a kind of different displaying symbol, and each point driving switch is common ground in integrated point driving switch inside; Inner each point driving switch of integrated point driving switch has only one group of normally opened contact, and only just closed under stressed situation, its one group of unique contact disconnects under the normal condition.
2.2 there is certain angle of inclination integrated point driving switch symbol display part, wake up in real work day, just ten driver's observation;
2.3 the light source of display part be for sending the light-emitting diodes of different colours, basic corresponding two light-emitting diodes of each switch, and a job when being corresponding switch work shows the corresponding electrical equipment of this switch at work; Another is a position display, shows the position of this switch.As for which kind of color is to require decision according to the switch of different performance and relevant laws and regulations.Each symbol has dividing plate between showing in addition, to avoid adjacent displaying symbol influence;
2.4 be low level during all switch connections, improve the reliability of whole electric system.
The beneficial effects of the utility model are, long service life is easy for installation, are convenient to operation.
(4) description of drawings
Below in conjunction with drawings and Examples the utility model is made specific description.
Fig. 1 is the main TV structure schematic diagram of a kind of embodiment of the present utility model
Fig. 2 is the left TV structure schematic diagram of Fig. 1
Fig. 3 is the backsight structural representation of Fig. 1
Fig. 4 is the electrical principle schematic diagram of Fig. 1
Among the figure, 1 symbol shows, 2 switch panels, and 3 shift knobs, 4 install bayonet socket, 5 insulation crusts, 6 wire harness connect connector, C1, D1, F1, G1, H1, D2, F2, G2, H2 are diode, Rc, Rd, Rf, Rg, Rh are current-limiting resistance
(5) embodiment
As Fig. 1-4 is structure and the circuit diagram of the utility model embodiment.
The integrated point driving switch of automobile shown in Fig. 1,2 and 3, its shell is made up of switch panel (2) and insulation crust (5), shift knob (3) and symbol are installed on the switch panel show (1), symbol shows that (1) has certain angle of inclination, light source is the light-emitting diode that can send out different colours, is in series with current-limiting resistance on the light-emitting diode.The side of insulation crust is fixed with installs buckle (4), and the back is equipped with wire harness and connects connector (6).Shift knob is a point driving switch, has only a pair of normally opened contact, and shift knob is for resetting certainly; Control circuit is by system controlled by computer.
As Fig. 4, when the driver puts the front fog lamp shift knob that makes a movement, its contacting, microcomputer receives corresponding electronic signal by the A3 terminal and latchs, when the driver stops crawl, contact 1,2 disconnects, microcomputer inner control program begins to carry out, and makes front fog lamp work, in the front fog lamp course of work, light-emitting diode D 1 works simultaneously, shows front fog lamp at work.Action implementation status and on off state are irrelevant.If will stop corresponding actions, mainly be to see that program receives the sort of signal and makes and stop action.Be to click the point driving switch button more generally speaking, light-emitting diode D1 quits work simultaneously simultaneously.When working as for D2 is according to relevant rules, in conjunction with actual conditions, and on-position lamp switch, software control, microcomputer control unit driving work.Wherein, Rc, Rd are current-limiting resistance, determine its parameter by diode operation electric current and system voltage.Critical alarm switch, main furnace building light switch among the figure, Rear Fog Lamp spare switch execution mode and front fog lamp are basic identical, no longer enumerate.
