Abstract

The utility model relates to an automobile combined switch with a control rear fog lamp. Aiming at the fact that a plurality of the existing automobiles are provided with independently controlled switches for the rear fog lamp, yet the control requirements of national standards GB-4785-1998 on the rear fog lamp can not be met; namely, only when a headlamp on full beam and a dipped headlamp are switched on, the rear fog lamp can be switched on, and the rear fog lamp can be switched on and off independently of any other lamp. The utility model achieves the requirements of the national standards by adding a normally open relay and a sampling control switch in a combined switch; the utility model does not change the existing whole vehicle circuit or influence the other functions of the combined switch; besides, the utility model can meet the requirements of whole vehicle assembly and maintenance markets.

Description

Combined switch

The utility model relates to a kind of automobile combined switch, especially band control fog tail lamp and in positive and negative two-polar combined switch is arranged.

The existing automobile that has fog tail lamp, great majority have taked to be provided with the circuit that independent fog tail lamp switch is controlled fog tail lamp, such as: vehicles such as SC6331, HFJ6350.Come into effect GB GB4785-1998 from October 1st, 1999, wherein 4.3.1.4.7 requires: have only when country beam, when passing light is opened, fog tail lamp just can be opened, and fog tail lamp can be independent of any other lamp and closes, and fog tail lamp can continuous working, till the position lamp is closed.Open once more, then repeat above-mentioned requirements.Obviously, new GB requires to fog tail lamp the logic self-retaining function to be arranged, and needs this function, and existing most of automobiles do not reach.Resetting new car load circuit can be up to standard, but can cause maintenance market inconvenience.

The purpose of this utility model is not changing existing car load circuit exactly, keeps the repertoire of existing combined switch again, can also reach the combined switch that 4.3.1.4.7 requires among the GB GB4785-1998.

Technical solution of the present utility model is, increased by a cover current sample and a treatment circuit in combined switch, realizing the logic self-sustaining controllable function to fog tail lamp, thereby reaches the requirement of GB.This circuit is made up of a normally opened relay and a controlling of sampling unit, and is installed on the existing combined switch base, and the no any difference of the manipulation of handle component control.There is multiple way of realization controlling of sampling unit in the circuit, and commonly used have two kinds of dry-reed tube and voltage comparators, and division is as follows:

Do the controlling of sampling unit with voltage comparator, the termination K of resistance R s ₂With a contact of normally opened relay, the other end is external to the fog tail lamp K switch ₃With the positive input of comparator, be used for setting up the datum of comparator positive input.The other end of the negative sense control termination Rs of comparator is when connecting K ₂After, when the voltage on the comparator negative sense control end was higher than datum, comparator just transferred conducting state to by off condition.Connect the B end behind the mouth tandem drive modules A M of comparator, the normally opened relay coil, then electric current passes through K ₂With the comparator of conducting to relay coil, make the normally opened relay closing of contact, because another termination K of normally opened relay contact ₁Mouth, the closure of relay contact, thus conducting K ₁Passage to comparator.If closed K again ₁, from K ₁Electric current just can replace K ₂, at this moment disconnect K again ₂, from K ₁Electric current still can keep K ₃Electric current output and keep the closure of normally opened relay, therefore formed self-hold circuit.Work as handle component like this and be in the OFF shelves, be i.e. position light switch K ₁With the K switch that is subjected to Der StandlichtScheinwerfer und Parkleuchtenschalter control ₂All be in off-state, at this moment if the fog tail lamp K switch ₃Closure, but no current passes through, and fog tail lamp can not be opened; When handle component is in the lampet shelves, i.e. position light switch K ₁Connect, because of not adhesive of relay, this moment, fog tail lamp still can not be opened; When handle component is in the headlight shelves, i.e. position light switch K ₁With the K that is subjected to Der StandlichtScheinwerfer und Parkleuchtenschalter control ₂All connect, because the Rs value is less, so the fog tail lamp K switch ₃Closure just has electric current to pass through, and fog tail lamp is opened, and electric current makes the voltage of comparator control end be higher than datum by behind the Rs simultaneously, the comparator conducting, and electric current is through K ₂, comparator, relay coil to combined switch inner exist hold opposite polarity B point with B, make the relay adhesive, from K ₁Electric current also received on the comparator; When handle component is retracted into lampet shelves, K ₂Disconnect, by from K ₁Electric current form self-hold circuit by comparator to relay coil, also keep fog tail lamp work simultaneously; When handle component is retracted into the OFF shelves, circuit is in full off-position again, and fog tail lamp can not conducting.

Make the controlling of sampling unit with dry-reed tube, the coil one termination K of dry-reed tube ₂With a contact of normally opened relay, the other end is external to the fog tail lamp K switch ₃Form sample circuit; When connecting K ₂After, the two-terminal of dry-reed tube transfers conducting state to by off condition; The terminal 11 of dry-reed tube with connect the normally opened relay contact after dry-reed tube coil one end is in parallel, connect the B end behind the another terminal 12 series connection normally opened relay coils, when connecting K ₂After, then electric current passes through K ₂, dry-reed tube is to relay coil, makes the normally opened relay closing of contact.Because another termination K of normally opened relay contact ₁Mouth, because of the closure of relay contact, thus conducting K ₁Passage to dry-reed tube.If closed K again ₁, from K ₁Electric current just can replace K ₂, at this moment, disconnect K again ₂, from K ₁Electric current still can keep K ₃Electric current output and keep the closure of normally opened relay, therefore form self-hold circuit, it is same that its principle of work and voltage comparator are made the controlling of sampling unit class.

As shown from the above technical solution, the automobile combined switch of band that the utility model provides control fog tail lamp has not only satisfied national standard, and does not change existing car load circuit and accessory, if offer society's maintenance, to the transformation of old car, up to standard, real is preferred plan.
