Description

Desktop electronic locker {digital mobile locking box}

The present invention relates to the storage of personal items or items that you want to keep secretly, more specifically, the cover of the hinge hinged to the lower barrel is opened by entering the password, and lightly press the cover again to close and At the same time it relates to a desktop electronic locker that is automatically locked.

Conventional and similar technologies include safes or digital safes, and safes are designed to store and protect valuables or money with very high security, such as individuals or businesses. It is not easy, and it is difficult to keep it close to the user, and it cannot be used in daily living space such as a personal desk, book flower, table, etc., and the existing safe is very expensive to manufacture because it aims for high security. It is set high. As a result, there is an unreasonable way to hide items that do not require much security or to be kept in an exposed place.

In order to solve the above problems, the present invention is made of plastic material so that it is easy to move and carry, and the design of various designs is possible. In addition to the basic opening / closing function and password change function, the usual time display function and a specific time zone By providing alarm function and audio-visual event function by melody and LED when the lid is opened, it is possible to organize personal items or valuables that are not greatly considered for security in everyday spaces, but not for thieves or robbers. The purpose is to provide protection from the group without being exposed and to provide such daily and practical contents in the user's surrounding space.

In order to achieve the above object, the present invention is largely made of a plastic material, the lower barrel 10 and the lid assembly 11 are fastened by the hinge 33, and the clasps to perform the opening and closing function and the locking function ( 18), solenoid 15, metal push rod 17, springs 16, 22, etc. are built in the cover assembly 11 and the lower cylinder 10, respectively, the control of the input and output and the interface (interface) In order to cover the printed circuit board 24, the keypad 35, the LCD 30, the LED 37, the speaker 52 is installed inside and outside the assembly 11, the configuration.

When the desktop electronic locker according to the present invention will be described in detail the configuration and operation principle through the accompanying drawings as follows.

5 is a view showing the opening and closing state of the electronic locker implemented by the present invention to explain the opening and closing operation which is a basic operation.

Figure (a) of Figure 5 is an open state when pressing the cover 11 in the direction of the arrow is closed and locked as shown in Figure (b) and does not open unless the solenoid 15 is operated.

When the solenoid 15 is operated in the direction of the arrow in Fig. 5 (C) to retract the clasp 18, the clasp 18 caught on the clasp fixing protrusion 20 is squeezed out and the pusher 21 as shown in Fig. (D). ) Slide the cover (11) to open the cover automatically.

For the operation as described above, the clasp 18, the solenoid 15, the solenoid metal pusher 17, the solenoid spring 16 are basically provided in the cover assembly 11, and the lower barrel 10 has a push rod reciprocating. A passage 23 is formed and a push rod 21 reciprocating therebetween is provided with a push rod spring 22 for pushing up the push rod, and the lid assembly 11 and the lower portion as shown in FIGS. 4 and 1. The mechanical opening and closing function can be performed by fastening the barrel by the hinge 33 to form a rotating shaft of the lid assembly 11.

When the user wants to open or close the mechanical opening and closing operation as the user intends, that is, when the password is entered, the door is automatically opened and maintained, and when the cover is pressed by hand, the operation is closed and locked simultaneously. In order to be operated by the electric and electronic elements, the solenoid must be operated. The operation principle and its configuration for operating the solenoid will be described in detail as follows.

As shown in FIG. 2, the cover assembly 11 is provided with a keypad 35 and an LCD window 30, which provides a user interface for entering, modifying, and canceling a password, and printing therein for controlling each hardware. The circuit board 24 is built-in, and the battery socket 32 is formed on the outside of the cover as the power supply unit of the present invention.

It provides a control system as shown in Figure 7 for the interface and operation of the present invention formed as described above and will be described in detail as follows.

The microcontroller unit (MCU) of FIG. 6 is called a microcomputer or a microcomputer and controls all functions on hardware and recognizes a logic signal input from the keypad 35 to recognize a specific program (operation, input, output). Control the surrounding hardware. The EEPROM 38 communicates with the MCU 50 and provides the main initial value of the program. The EEPROM 38 has semi-permanent storage of passwords and main data. The SMPS 51 has many forms, but in the present invention, it is a DC / DC converter. The circuit is composed of ferrite core transformer, diode, and transistor, and it converts DC 3V to about DC 42V by high speed switching. In order to use electric energy as the driving power of the solenoid 15, the capacitor is charged to a capacitor of 220 microfarads or more, and a specific voltage for detecting the time when DC42V charging is completed in this capacitor is transmitted to the MCU 50. When the sensing unit (d) is configured and the DC42V charging is completed in this way, the MCU 50 transmits a trigger signal to the solenoid trigger unit (a) and the solenoid. De tree refused (a) operates the solenoid 15 is subjected to immediately trigger (trigger).

As described above, when the user inputs a password, the MCU 50 compares the input data with preset password data to induce boosting if true and operate the solenoid 15, and if not, to realize basic opening and closing operation. The predetermined password may be arbitrarily changed by the MCU 50 and the EEPROM 38.

Other functions as a daily use are basically provided with a clock function, alarm function, melody selection function, key button sound selection function, the melody is activated after the cover is opened, and the LED 37 blinks. The above-mentioned contents, that is, the audio-visual contents combining the blinking of the LED 37, the display of the LCD 30, the utterance of the speaker 52 can be realized by the control system of the configuration as shown in FIG. More specifically, the MCU 50 may be realized by receiving an input from the keypad 35 or outputting to the speaker 52, the LCD 30, and the LED 37 by internal calculation.

Looking at the effect of the desktop electronic locker according to the present invention.

Unlike general safes and security equipment aimed at security against unusual situations such as theft and robbery, the present invention is not subject to great limitations in production because it aims to secure daily privacy from family and colleagues. Therefore, the desktop electronic locker provided by the present invention can pursue various shapes by using plastic material, and it is easy to move and carry by the light material and smart size, as well as the clock function and alarm function around users. Providing audiovisual content can add to everyday practicality. In addition, the cover is automatically opened by password input, and the cover is lightly pressed again, providing a quick and easy opening and closing method that automatically closes and locks at the same time.
