When a taxi is robbed, a driver can conveniently and invisibly operate the utility model in time because the utility model has the advantage of visual and flexible display, the driver can get help from passersby or traffic policemen, and the driver can effectively and actively perform self-defense.
Description
The utility model belongs to a kind of improved taxicar display alarm defence device, is particularly suitable for the taxi driver and is used to take precautions against criminal hijack, uses when avoiding suffering personal injury.
The method that existing taxicar is used to take precautions against criminal hijack normally installs protection railing additional behind driver's driver's seat, be used to isolate the ruffian near the driver; Perhaps mould a how bright bulb in the shell as the signal of reporting to the police, show the danger that the driver ran at the taxi board of roof.Also have and report to the police by the mode of radio transmit signal.But these modes all can not stop the ruffian to do violence, rob car, more can not carry out self-defence and self-protection.
The purpose of this utility model provides a kind of taxicar display alarm defence device, and it can demonstrate the state of hiring a car, and driver's energy hidden operation defense device, thereby has overcome above-mentioned defective.
The purpose of this utility model is to realize like this, it is made up of display alarm part, defence part and countersabotage protection part, its display alarm part is made up of telltale, control interlocking switch, monitor switch and stroboscopic controller, monitor switch divides two-way by the control interlocking switch, one the tunnel connects a telltale, another road serial connection stroboscopic controller and another telltale; The defence part is in series by boost master cock and high pressure generator and pulse-width controlled derailing switch, and the secondary receiving electrode cushion of high pressure generator is sat cover, and the base stage of pulse-width controlled switch connects the pulse-width controlled derailing switch; Countersabotage protection part is made up of signal relay switch, signal relay, signal relay normally open contact and 12V signal lamp; signal relay switch and signal relay are in series; be attempted by both ends of power then, be attempted by both ends of power after signal relay normally open contact and the indicator lamp series connection.High brightness LED is installed in hires out board and mould in the shell, and the control line that will control interlocking switch and monitor switch causes in the operator's compartment; The frequency and the pulse duty factor of stroboscopic controller are adjustable, are 2～3 seconds when being output as high level (12V), are 1 second short type wave impulse during low level (0V).The master cock of boosting is installed in the operator's compartment, and the 12V storage battery makes high pressure generator pay the limit and produces the adjustable high-voltage pulse of pulsewidth by pulse-width controlled derailing switch, pulse-width controlled switch, and outputs to and be installed in the car seat top electrode cushion and sit and put.The normally closed interlock of signal relay is connected with the 12V signal lamp, the parallel installation with electrode wires of 12V signal lamp lead-in wire.
The utility model intuitive display is flexible, and the driver operation defense device is convenient timely, hidden, so during the taxicar catastrophe, the driver can in time be helped, and can defend oneself effectively energetically.

Below in conjunction with accompanying drawing the utility model is described in further detail.
With reference to Fig. 1,2,12V storage battery [1] is in parallel with monitor switch [3], the master cock of boosting [8], signal relay switch [13] respectively through fuse [2].The display alarm part is by light-emitting diode or high brightness LED, and telltale of forming on the circuit plate [5] and telltale [7] one in front and one in back are installed in the taxi board and mould in the shell, and former installation site and fixed form that the taxi board is moulded in the shell are constant.Monitor switch is in parallel with often the opening of interlocking switch [4], normal-closed end respectively, the normally closed button of interlocking switch is connected with telltale [5], receive the negative terminal of 12V storage battery through telltale [5], after often the driving button and stroboscopic controller [6] and telltale [7] are connected of interlocking switch, connect the negative terminal of 12V storage battery.Interlocking switch [4] control telltale [5], [7] show different captions, just often show: " taxi ", " Taxi " captions; When running into the ruffian and rob car, the taxi driver can secretly move interlocking switch, and telltale demonstration is similar to " SOS " or other calls for help captions.The control of interlocking switch [4] causes in the operator's compartment, according to different situations operation interlocking switch, makes telltale show different captions by the driver.Letting alone under ruffian's the situation to warnings such as roadside pedestrian, traffic constables, so that get help and rescue.The frequency and the pulse duty factor of stroboscopic controller [6] are adjustable, are 2～3 seconds when being output as high level (12V), are 1 second short type wave impulse during low level (0V).
The master cock of boosting [8], pulse-width controlled derailing switch [9], high pressure generator [10], pulse-width controlled switch [11] and electrode cushion are sat cover [12] and have been formed the defence part, the master cock of boosting [8] is through the collecting electrode of high pressure generator [10] former edge joint pulse-width controlled switch [11], the emitter of pulse-width controlled switch connects the negative terminal of 12V storage battery, and the base stage of pulse-width controlled switch connects the negative terminal of 12V storage battery through pulsewidth master cock device [9]; The edge joint electrode cushion of paying of high pressure generator is sat cover [12].The 12V storage battery makes high pressure generator [10] pay the limit and produces the adjustable high-voltage pulse of pulsewidth by pulse-width controlled derailing switch [9], pulse-width controlled switch [11], and outputs on the electrode cushion seat cover [12] of seat, and the electrode cushion is sat in the cover [12] and added electrode wires.Under normal circumstances, high pressure generator does not produce high pressure, and when calculating suffers that the ruffian injures; produce high-tension current by the driver operation master cock high pressure generator that boosts, sit cover by the electrode cushion ruffian is temporarily subdued, but do not hinder its life; from reaching self-defence, protect the purpose of self.
Formed countersabotage protection part by signal relay [14], signal relay contact [15], 12V signal lamp [16] and signal relay switch [13]; signal relay switch [13] is with after signal relay [14] is connected; connect the negative terminal of [1]; signal relay contact [15] connects the negative terminal of [1] with after 12V signal lamp [16] is connected.The lead-in wire loop of 12V signal lamp [16] and the defence parallel installation of electrode wires partly.Destroy electrode wires as ruffian's desire, will destroy 12V signal lamp loop earlier, the lead-in wire of signal lamp must be destroyed prior to electrode wires, and the driver is can be by the 12V signal lamp bright or do not work to judge whether the defence part is destroyed, so that in time take corresponding defence measure.But the normally closed interlock and the signal lamp series connection of signal relay are adopted in signal indicating mode river, and indicator light colors was one red one green separating.
