Abstract

The utility model relates to a no-passenger display board turning axle and positioning structure for taxi, which is composed of a turning axle, balls, a spring, etc., wherein, the turning axle is provided with two insulation positions which are different with 90 DEG at the direction of the turning axle; the twoballs can contact with the insulation positions respectively when the turning axle is rotated, which forms a switch structure and a positioning structure. The utility model has the advantage of simple structure, and overcomes the defects of the existing empty taxi. The joints of opening and closing are abrasion-proof and has a long service life.

Description

Taxi empty wagons direction board rotation axis and location structure

The utility model is mainly used in taxi industry, it usually and taximeter be used.

The empty wagons board is except being used for being used as the operation state indication (operation or empty wagons) of taxi, also have following function concurrently: 1, fee register interlock function: the switching signal that operation/empty wagons two states is provided for fee register, like this when fell " empty wagons board " enters operation, fee register enters the valuation state thereupon, and the way that realizes is to provide a switching signal over the ground by " empty wagons board " is movable to fee register usually.As Fig. 1, when erecting, the cutter of switch k1 engages with the e point " empty wagons board ", and for pilot lamp provides ground circuit, k2 closes as this moment, then+the 12v power supply enters through lampet, gets back to Y by the e contact from X, constitutes the loop, and lampet is bright.When overwhelming the empty wagons board, k1 cutter and f contact join, and for fee register provides earth signal, make fee register enter operation state, and k1 cutter and e point disconnect simultaneously, cut off the lampet current supply circuit, and lampet extinguishes thereupon.2, night indicator light switch: to night people do not see " empty wagons board ", at this moment just need open indicator light switch k2, light " empty wagons board " and ceiling light.Require but have: when falling " empty wagons board ", pilot lamp should extinguish, and represents carrying, clearly indication is provided for the night passenger, Fig. 1 indicated this function roughly through structure.

Great majority " empty wagons board " roughly all possess These characteristics through structure at present.The method and structure design that just realizes is bad, because the each operation of driver all will be pulled once, this structure rapid wear easily grinds, and fragile, and above-mentioned functions is affected.Its major failure is as follows: 1, the switch k1 among Fig. 1 makes switch member with microswitch, and microswitch itself exists many shortcomings, and major defect is not to be durable, after after a while, plastic key wearing and tearing, contact corrosion, loose contact, the contact heating.2, night, ceiling light, " empty wagons board " were when pilot lamp is bright, and the contact electric current that flows to microswitch is big, and the contact resistance after corrosion after a while strengthens, and when big electric current flows through, can generate heat, and burns out switch when serious.3, the location is malfunctioning, because driver's plate is moving often, the inevitable requirement rotational structure is durable, yet domestic main location structure as shown in Figure 2 at present: the pressure by the center pit rubber bar withstands ball, and ball is entered in recessed being pickled with grains or in wine of plastic stent, forms location structure, when driver's plate moves, ball enters another groove location, with feel along interior poor slip.But this structure time one length, slip number of times more than, groove reaches and easily polishes, and loses positioning function.Cause corresponding switch break-make shakiness back and forth thus, make the fee register job insecurity.See Fig. 3, Fig. 4.

The purpose of this utility model is to overcome above-mentioned shortcoming, and it is durable to design rotational structure, and for fee register provides the open and close signal accurate, and its durability is not subjected to empty wagons board rotation axis and location structure that night, ceiling light influenced.

The utility model be achieved in that by conductive characteristic good material rotate the axle 1, two insulation positions 2 are arranged on rotation axis 1,3, two insulation positions 2,3 are upwards differing 90 degree in 1 week of rotation axis, ball 4 and 5 withstands rotation axis 1 respectively under the pressure of spring 6 and 7, when ball 5 contacts with insulation position 3, ball 4 just in time changes in the groove 9, when ball 4 contacts with insulation position 2, ball 5 just in time changes in the groove 10, support 8 has contact B with spring 6 connecting places, support 8 has contact C with spring 7 connecting places, has lead that ball 4 is linked to each other with the B point in the spring 6, has lead to make ball 5 and C point in the spring 7, A is on the rotation axis 1 a bit, make insulation position 2 when contacting when rotation axis 1 forwards to, just make A-C conducting, A-B disconnection with ball 4, equally, make insulation position 3 when contacting when rotation axis 1 forwards to, just make A-B conducting, A-C disconnection with ball 5.Like this, when forming construction of switch, also formed location structure, combined together in the switch location.

Because the object that slides is between ball and the rotation axis 1 relatively, thus more wear-resisting than the slip between ball and the plastic processing frame, fundamentally solved problem easy to wear.Each spring center all is used to lead to lead, makes spring not undertake electric action.So just avoided spring resistance can be when big electric current the heating rapid wear.

Embodiment:

By conductive characteristic good copper product rotate the axle 1, two insulation positions 2 are arranged on rotation axis 1,3, two insulation positions 2,3 are upwards differing 90 degree in 1 week of rotation axis, ball 4 and 5 withstands rotation axis 1 respectively under the pressure of spring 6 and 7, when ball 5 contacts with insulation position 3, ball 4 just in time changes in the groove 9, and when ball 4 contacted with insulation position 2, ball 5 just in time changed in the groove 10, support 8 has contact B with spring 6 connecting places, support 8 has contact C with spring 7 connecting places, has lead that ball 4 is linked to each other with the B point in the spring 6, has lead to make ball 5 and C point in the spring 7, A is on the rotation axis 1 a bit, make insulation position 2 when contacting when rotation axis 1 forwards to, just make A-C conducting, A-B disconnection with ball 4, equally, make insulation position 3 when contacting when rotation axis 1 forwards to, just make A-B conducting, A-C disconnection with ball 5.Like this, when forming construction of switch, also formed location structure, combined together in the switch location.
