Abstract

The utility model relates to an electronic combination lock, in particular to a pressure sensing type electronic combination lock, which structurally comprises a code display screen, a confirm button, an upper tuning button, a lower tuning button and a pressure sensing button. The pressure sensing button is connected to an internal circuit of the code display screen through a chip, and the confirm button, the upper tuning button and the lower tuning button assist work of the pressure sensing button, and the code display screen is provided with a shield. The pressure sensing type electronic combination lock is simple in structural design, the risk of code disclosing is eliminated since the mode of inputting codes by the aid of code keys is omitted, and sensing codes can be input quickly.

Description

A kind of pressure inductive electronic password lock

Technical field

The utility model relates to a kind of electronic password lock, especially relates to a kind of induction type electronic coded lock.

Background technology

Coded lock is a kind of of lock, and what use during unlatching is a series of numeral or symbol.The password of coded lock all is to arrange but not real combination usually.The partial password lock only uses a rotating disk, several video discs or the cam rotation in the lock; Also some coded lock be rotate one group several be carved with the thumb wheel circle of numeral, directly drive the machinery of lock inside.

Mechanical code lock is common in the bicycle lock that lower security is set, and generally uses a plurality of groups of circles.There is recess the centre of each circle.The axle at center of lock, on the tooth of several protrusions is arranged, be used for blocking and dial circle.When group circle forwarded correct password combination to, lock just can be opened.This lock is opened the most easily.A lot of this type locks need not at all to know that password can both open.Only if its internal component is made perfectly, otherwise as long as be pulled outwardly axle, one of them tooth just can more be strained than other and dial circle.At this moment the circle of dialling that moves in turn and be tightened up until hearing slight " card " sound, representes that this tooth has got into correct recess.Heavily cover this step, just can open lock very soon.

Electronic password lock then is a kind ofly to come control circuit or chip operation through password input, thus the closure of control mechanical switch, accomplish unblank, the electronic product of locking task.Its kind is a lot, and easy circuit product is arranged, and the cost performance high product based on chip is also arranged.Using wider electronic password lock now is to be core with the chip, realizes through programming.

To sum up state no matter be mechanical code lock or electronic password lock, this cryptographic key all exposes undoubtedly in the time of its input password, if there is the people on the next door when opening coded lock, then this password is easy to stolen.So this is the common fault of all coded locks.

Summary of the invention

The utility model technical problem to be solved is: provide a kind of simple in structure, suitable general population to use, avoid the side if having the people to input password also is difficult for stolen safe coded lock, thereby solve the common fault that all import the coded lock of passwords.

In order to reach above-mentioned purpose; Technical scheme below the utility model has adopted: a kind of pressure inductive electronic password lock; Its structure comprises: password display screen, acknowledgement key, on finely tune key, finely tune key, pressure sensitive key down, the described pressure sensitive key chip that was connected with password display screen internal wiring; Acknowledgement key, on finely tune key, finely tune key down and assist in the work of pressure sensitive key.

Above-mentioned password display screen is provided with door.

The beneficial effect of the utility model: simple, the no cryptographic key input of project organization, the risk, the induction password that do not exist password to leak are imported fast.

Description of drawings

Fig. 1 is the utility model pressure inductive electronic password lock structural representation.

1-password display screen among the figure, the 2-acknowledgement key, the last fine setting of 3-key, 4-be the fine setting key down, 5-pressure sensitive key.

The specific embodiment

Do a detailed explanation below in conjunction with the specific embodiment of 1 pair of the utility model of accompanying drawing.

Embodiment:: a kind of pressure inductive electronic password lock, its structure comprises: password display screen 1, acknowledgement key 2, on finely tune key 3, finely tune key 4, pressure sensitive key 5 down, described pressure sensitive key 5 chip that was connected with password display screen 1 internal wiring; Acknowledgement key 2, on finely tune key 3, finely tune key 4 down and assist in pressure sensitive key 5 work.

Described password display screen 1 is provided with door.

When user's press pressure sensor key 5; Inner setting through pressure sensitive and System on Chip/SoC; Its chip can be confirmed the data on rising or the decline password display screen 1 according to the dynamics of pushing; When password approaches the numerical value of former setting, can be through last fine setting key 3, finely tune that key 4 is auxiliary confirms code datas down.When password is shown as former setting value, presses acknowledgement key 2 and promptly get into the unlatching secrecy.

Password demonstration amount on the general password display screen 1 is six, because the dynamics of this pressing force is descending, the password value that institute is former four is confirmed the most easily.When confirming preceding four password values, chip can let password display screen 1 forbid showing the password of firm affirmation at 0.6-0.8 in the time of second, so just further guaranteed the safety of password.

Claims

1. pressure inductive electronic password lock; Its structure comprises: password display screen (1), acknowledgement key (2), on finely tune key (3), finely tune key (4), pressure sensitive key (5) down, it is characterized in that: pressure sensitive key (5) chip that was connected with password display screen (1) internal wiring; Acknowledgement key (2), on finely tune key (3), finely tune key (4) down and assist in pressure sensitive key (5) work.
