The utility model relates to a kind of automobile door lock anti-joyride device, particularly a kind of cipher automobile door lock anti-joyride device.

(2) background technology

General automobiles door lock anti-theft security is poor, can open car door as long as obtain key; And existing cipher automobile anti-theft lock existing problems are that password input key is too small, status requirement to user's finger when password is imported is very accurate, some deviations a little just may cause the password of actual input and setting code inconsistent, and cause very big inconvenience for car owner's use, especially out of doors or night insufficient light situation under, the inconvenience that this situation is brought will be bigger.

(3) utility model content

The purpose of this utility model is at above-mentioned existing problems, and the cipher automobile door lock anti-joyride device that a kind of theftproof performance is good, password input convenience is accurate, installation is simple, safe and reliable is provided.

The technical solution of the utility model

A kind of cipher automobile door lock anti-joyride device, it is characterized in that: form by Digiplex, wireless receiver, executive circuit, micro controller system, power supply and infrared ray input keyboard, Digiplex and infrared ray input keyboard are controlled the input of password jointly, and whether correct micro controller system be used to judge password input and the action by executive circuit control electromagnetism unlocking mechanism; The circuit of infrared ray input keyboard is by power supply; the ground connection position; infrared light emitting diode; infrared receiver diode; aerotron and resistance R 1～11 constitute; wherein R1～10 are played and are protected diode to act on; it is as follows that the arranging of infrared ray input keyboard is provided with: six groups of infrared transmitting devices and six groups of infrared receivers are installed on the position, edge of automobile door glass; utilize this plane of automobile door glass and 12 groups of infrared; interface for password input of the common composition of receiving device; wherein three groups of infrared transmitting devices and three groups of infrared receivers on level attitude in twos over against; three groups of infrared transmitting devices and three groups of infrared receivers on vertical position in twos over against; cross altogether and form nine zones; assignment is nine numerals of 1-9 respectively; two infrared rays in arbitrary group receive or emitting diode between spacing equate and adjacent diode between distance be not more than 1cm; the object that promptly guarantees finger or other corresponding sizes can shelter from one or more than one infrared ray light paths when dropping in this zone the optional position; thereby as long as will point or the object of other corresponding sizes drop on any one position in certain zone will make by the level of this position and have an infrared ray light path to be blocked vertically to cause the cooresponding level in this zone simultaneously at least and vertical two groups of infrared receivers on certain any current potential produce saltus step simultaneously, just can finish the input of the numeral of relevant position by drawing and write down this jump in potential.

The utility model has the advantages that: 1. theftproof performance is good, must obtain remote-control key and password simultaneously and just can open car door and start engine; 2. the password input is accurately convenient, utilizes this plane of vehicle window to increase the face area of each digital keys greatly, has solved conventional combination lock because the problem of input error that the finger position inaccuracy causes or password input inconvenience in evening; 3. install simply, because infrared ray has the naked eyes invisibility, so can not influence the outward appearance of car.

(5) specific embodiment

Embodiment:

A kind of cipher automobile door lock anti-joyride device, as shown in Figure 1, form by Digiplex 11, wireless receiver 12, executive circuit 13, micro controller system 14, power supply 15 and infrared ray input keyboard 10, Digiplex 11 and the 10 common inputs of controlling passwords of infrared ray input keyboard, micro controller system 14 are used to judge whether the password input correctly also controls the action of electromagnetism unlocking mechanisms by executive circuit 13; The circuit of infrared ray input keyboard 10; as shown in Figure 2; by power supply 15; ground connection position 16; infrared light emitting diode 17; infrared receiver diode 18; resistance R 1～11 constitutes; wherein R1～10 are played and are protected diode to act on; resistance is 2.2k ohm; R11 is 10k ohm; infrared ray input keyboard 10 is by 1～9 numeral; i.e. emission group of six groups of infrared transmitting devices 1～6 and the i.e. reception group of six groups of infrared receivers 1～6 constitute and are installed on the position, edge of automobile door glass; common form an interface for password input, two infrared rays in arbitrary group receive or emitting diode between spacing equate and adjacent diode between be not more than 1cm apart from d.When the infrared ray light path in the actv. input area 20 all is not blocked, 22 is high potential, when finger drops in the zone 20 during the optional position, can block one or more light path, infrared receiver diode on the light path that is blocked will conducting, 22 can become active potential, and 22 current potentials are finished from height-low saltus step.This installs operating control procedure, as shown in Figure 3, the user at first uses Digiplex 11 to send unlock command and follows and send one group of password, after wireless receiver 12 is received password, send micro controller system 14 to and judge whether this group password is correct, mal is then cancelled this operation, correctly then opens 5V voltage 15, and the user just can input password by input keyboard then.As shown in Figure 1, when finger drops on regional 7 the time, will make that one or more than one infrared ray light paths are blocked in reception group 1 and the reception group 6, thereby in high-low jump in potential of 22,25 two output, through after the combination of joint denial gate 28, the numeral of input micro controller system is 7, promptly finishes the input of numeral 7.After the user inputed password successively, micro controller system 14 judged whether password is correct, and mal is then cancelled this operation, correctly then controls executive circuit 13 and finishes unlocking action.Equally, when locking, the user uses Digiplex 11 to send to lock order and follows and send one group of password, after wireless receiver 12 is received password, send micro controller system 14 to and judge whether this group password is correct, and mal is then cancelled this operation, correctly then controls executive circuit 13 and finishes the action of locking.
