Description

A method for setting a key code of a mechanical key groove is disclosed in US Pat.

The present invention relates to a method of setting a key code of a mechanical key groove groove, more particularly, to a method of setting a key code of a groove groove of a mechanical key as many as possible And a key code setting method of the key-groove groove.

Generally, a vehicle is provided with a starter key device including a lock cylinder for starting an engine on one side of a driver's seat, and a mechanical key carried by an operator through a key insertion hole formed in the starter key device is inserted into the lock cylinder And is configured to start the engine by operating.

In recent years, when the driver approaches the vehicle while carrying a portable radio device (e.g., KEY FOB) due to the introduction of the immobilizer system, when a predetermined authentication signal is received from the approaching portable radio device and is read as a normal user The driver can be provided with an unlocking function of the vehicle door and the driver can operate the engine by simply pushing the start button switch provided at one side of the driver's seat.

However, even if the key is not inserted and rotated at all through the key insertion hole as described above, there is a risk that the driver loses the portable wireless device, and at this time, a separate emergency key (mechanical key) is used So that a rotary operation is required.

1 is an exploded perspective view showing an example of a starter key device for a vehicle according to the prior art.

A starter key device (1) is provided on one side of a steering wheel (not shown) of a driver's seat so that a mechanical key carried by a driver can be inserted.

1, the starter key device 1 includes an assembly holder 10 for mediating engagement with a vehicle, and a hollow portion 15 formed in the assembly holder 10, The rotor 20 is provided with a plurality of lock plates 45 to be movable through a plate insertion hole 40 formed to penetrate the rotor 20 in a direction orthogonal to the rotation axis direction of the rotor 20 And a key insertion hole 30 into which a mechanical key 100 having a predetermined shape is inserted is formed in the rotation axis direction of the rotor 20.

The plurality of lock plates 45 and 55 are formed with penetration portions (not shown) through which the mechanical key 100 passes. When the mechanical key 100 is inserted, the plurality of lock plates 45,55) are aligned in a direction orthogonal to the rotation axis direction of the rotor 20 by being hooked according to the shape of the groove groove 120 formed on any one of the wide surfaces 110 of the mechanical key 100.

However, the groove groove 120 needs to be manufactured as much as possible with respect to a vehicle manufactured to enhance security. For example, assuming that 100,000 vehicles are manufactured, the groove groove 120 has a shape peculiarly matching with the star key device installed in 100,000 vehicles, And the key must not be able to operate the starter key device (1) of the own vehicle with the key (100).

2 is a conceptual diagram for explaining a key code setting method of a mechanical key groove sub-groove inserted in a starting key device of a vehicle according to the related art.

The mechanical key groove 120 is formed on one of the wide surfaces 110 of the mechanical key 100 in a recessed shape recessed in the thickness direction.

In the mechanical key groove groove 120, the maximum number of machinable shapes is determined according to a basic unit of a tool (not shown) for machining it.

For example, as shown in FIG. 2, when a minimum unit of a shape that can be changed to a basic unit of the tool is set and is expressed by a matrix, it is assumed that the matrix consists of 5 rows and 8 columns. The maximum number of fabricatable grooves 120 is

Figure 112015061339204-pat00001
As a result, 390,625 possible shapes can be obtained.

However, in practice, the maximum number of the mechanical key groove grooves 120 can not all be applied to actual products. This is because the regulations related to the manufacture of the mechanical key 100, the insertion feeling of the mechanical key 100 to the lock cylinder (not shown), and the machinability of the mechanical key 100 The key code for making the shape of the groove groove 120 unsatisfactory in consideration of the predetermined condition will be deleted.

3 is a schematic view illustrating a key code setting method of a mechanical key groove groove according to the related art.

As an example of a key code setting method of a conventional key groove groove according to the related art, as shown in FIG. 3, all the matrices displayed in the case of being composed of 5 rows and 8 columns are listed. For example, And the row B, C, D, ... are compared in descending order to delete the key code from which the shape satisfying the predetermined condition is manufactured.

However, as shown in FIG. 3, since the C row and the F row deleted compared with the A row are already deleted rows, there is a possibility that the comparison row or the comparison target row which can be compared with the other row in the above- And the reliability is deteriorated, which is different from the number of remaining key codes in the ascending order comparison, which is performed in reverse order from the last row to the above-mentioned A row.

In addition, the number of remaining key codes remaining available due to deletion of the key code by the key code setting method of the conventional key groove groove according to the related art is only about 1000, The number of the star key devices 1 that can be operated through the mechanical key 100 of the key switch 1 is more than ten, and the security is deteriorated.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned technical problems, and it is an object of the present invention to provide a key code of a mechanical key groove groove capable of enhancing security by generating a key code of a groove groove of a great number of mechanical keys as much as possible.

A preferred embodiment of the key code setting method of the mechanical key groove groove according to the present invention is such that, as shown in FIGS. 1, 2, and 4, the locking cylinder (not shown) of the mechanical key 100 The number of arbitrary equal sections dividing the width of the groove groove 120 formed in a direction orthogonal to the inserting direction of the lock cylinder 120 becomes a row, So that the number of the lock plates (45, 55) sequentially arranged in the inserting direction of the mechanical key (100) inside the lock cylinder is aligned in a matrix so as to be moved in a direction orthogonal to the inserting direction (Hereinafter, referred to as a "first setting row") and the remaining rows among the matrices set by the matrix setting step (S10) Dissatisfied with the condition of A step of imposing a condition (S20) for displaying the number of the steps, and a step of removing a row having the largest number of the comparison row indicated by the condition imposing step (hereinafter referred to as a 'removed row') (Hereinafter, referred to as a 'second setting row') of the remaining rows except for the first set row among the remaining rows excluding the removed row by the deletion step S30, (S40) of repeating the condition imposing step (S20) and the deleting step (S30) using the remaining rows except for the row in which the comparison is performed, and the comparing step (S30) in the repeating step (S40) And an ending step S50 when the number of the rows is all '0'.

In the matrix setting step S10, the arbitrary equal interval set in the row may be determined by a regulatory rule relating to the manufacture of the mechanical key 100, a compacting condition of the lock cylinder, May be set in consideration of the insertion feeling of the lock cylinder 100 and the machining property of the mechanical key 100.

Regulatory regulations relating to the manufacture of the mechanical key 100 are not limited to the laws in the home country but also the laws and regulations that are commonly used worldwide are also applicable and it is desirable to satisfy the international regulations as much as possible.

On the other hand, the compacting condition of the lock cylinder is designed so that a lock cylinder of the minimum volume can be designed on the condition that the same basic tool is used. Generally, when the volume of the lock cylinder is reduced, In this case, it is of course possible to reduce the number of set lines.

The inserted sense of the mechanical key 100 with respect to the lock cylinder refers to a sense of latching when the key is inserted into the lock cylinder of the mechanical key 100 when the key is inserted into the lock cylinder 45 or 55 , Or at least a change in the shape of the groove groove 120 to such an extent that the user can feel the feeling of the latching.

The machining characteristic of the mechanical key 100 means the same tool size of the basic unit. However, when the basic unit of the tool is reduced at least, the number of the rows increases. However, This also means that the basic unit should be determined in consideration of the degree of workability.

In a preferred embodiment of the key code setting method of the mechanical key groove groove according to the present invention, the predetermined conditions are merely illustrative, and in various circumstances the predetermined conditions may be further added, It is natural that it is possible.

In addition, the predetermined condition may be used in the same concept as the predetermined condition used in the condition imposing step (S20).

For example, in the condition imposing step (S20), the predetermined condition is a condition that the regulation rule related to the manufacture of the mechanical key 100, the compacting condition of the lock cylinder, the lock of the mechanical key 100 (Hereinafter, referred to as 'setting column') of the first setting line or the second setting line is set in consideration of the insertion feeling on the cylinder and the machining characteristic of the mechanical key 100 And the difference from the same column of the comparison row being compared with the displacement according to the X, Y coordinate system.

According to a preferred embodiment of the key code setting method of the mechanical key groove groove according to the present invention, as shown in FIG. 4, in the condition imposing step (S20), the first setting line and the remaining rows are respectively And all of the comparison rows unsatisfying the predetermined condition are displayed.

This is because, in a preferred embodiment of the present invention, the key code setting method of the conventional mechanical key groove groove is compared with the key code setting method of the conventional key groove groove in descending order, And the comparison row which is not satisfied with the condition of the comparison row is displayed. Thus, the deletion of the comparison row which is not required to be deleted can be prevented in advance.

More specifically, after all the comparison rows unsatisfying the predetermined condition are indicated in the condition imposing step S20, only the row (removed row) showing the largest number of comparison rows is deleted in the deletion step S30 Thereby preventing unnecessary deletion of the remaining rows in which a number of comparison rows smaller than the removed row is displayed.

Here, after the removed row is removed by the deletion step S30, the remaining row excluding the removed row and the remaining row excluding the first setting row that has already been the comparison reference of the comparison row are used The condition imposing step (S20) and the deleting step (S30) are repeated.

The condition imposing step (S20) and the deleting step (S30) are terminated when no comparison row is unsatisfactory even though the remaining row is compared with the reference row to be compared. Hereinafter, this will be referred to as an 'end step (S50)' for convenience.

A preferred embodiment of the key code setting method of the mechanical key groove groove according to the present invention is characterized in that a key for obtaining the maximum number of the shape of the groove groove 120 by the number of the remaining rows in the ending step S50 And may further include a code acquiring step (unlabeled sign).

That is, since all of the remaining rows correspond to the key code satisfying the predetermined condition, the maker of the mechanical key 100 is able to manufacture the mechanical key 100 having more security do.

Actually, the mechanical key 100 made of 5 rows and 8 columns has 390,625 groove grooves 120 that can be manufactured, but according to the conventional key code setting method, only about 1,000 grooves 120 have security On the other hand, according to a preferred embodiment of the key code setting method of the mechanical key groove groove according to the present invention, it is possible to secure the shape of the groove groove 120 having approximately 7,000 to 10,000 security properties.

A key code setting method of a mechanical key groove groove according to the present invention will be described with reference to FIG.

First, as shown in Fig. 4, a comparison row is displayed which is dissatisfied with the predetermined condition by comparing each of the remaining rows based on the row A indicated by the first setting row. In FIG. 4, when the comparison is made on the basis of the row A, if it is assumed that the predetermined condition is the row B having the comparison row which is most unsatisfied, the row B is deleted by the deletion step S30.

Then, since the row B is the deleted row, it can not be the second setting row in the repeating step S40, but can not be the comparison row. Therefore, It is possible to prevent the deletion of a row unnecessarily deleted by deletion.

On the other hand, if a plurality of rows in the comparison row have the same number with a comparison row in which the predetermined condition is dissatisfied, it is preferable to delete all the rows in the deletion step S30. As a result, the repeating step S40 is repeated until the number of the comparison row unsatisfying the predetermined condition is zero (0) by the ending step S50.

A preferred embodiment of a key code setting method of a mechanical key groove groove according to the present invention has been described in detail with reference to the accompanying drawings. However, it should be understood that the embodiments of the present invention are not necessarily limited to the above-described preferred embodiments, and that various modifications and equivalents may be made by those skilled in the art something to do. Therefore, it is to be understood that the true scope of the present invention is defined by the appended claims.
