Description

Vehicle license plate coupling device {COUPLING APPARATUS FOR NUMBER PLATE OF VEHICLE}

The present invention relates to a license plate coupling device for a vehicle, and more particularly, to a coupling device usable when coupling a license plate to a vehicle.

The license plate of a vehicle means that the registration number for each vehicle, which is given by a combination of letters and numbers, is engraved on a rectangular plate. The license plate of such a vehicle is usually attached to a designated place of the vehicle, for example, on the front and rear of the vehicle, respectively.

A seal is installed on the license plate of a vehicle according to domestic laws and regulations. Sealing is to prevent forgery or theft of the license plate of a vehicle, and once installed, it is impossible to reinstall unless it is intentionally damaged.

In order to comply with domestic laws and regulations, a structure for installing a seal is prepared in advance for domestic vehicles when the vehicle is manufactured. For example, a through hole through which a sealing bolt for fixing the seal can pass is formed in a vehicle body such as a trunk cover or a rear beam. Accordingly, the seal can be installed by passing the sealing bolt coupled with the nut through the through hole formed in the vehicle body and the license plate, and fixing it using a washer and a pin from the opposite side.

On the other hand, imported vehicles do not have a through-hole through which a sealing bolt can be installed in advance in the vehicle body. Therefore, in imported vehicles, unlike domestic vehicles, a seal is installed using a short sealing bolt for imported vehicles and a license plate coupling device (auxiliary plate) with built-in nut for imported vehicles.

In this current situation, there are things that need to be improved in several aspects.

First, there is a growing demand for using a license plate coupling device for various reasons. When a license plate coupling device with a built-in nut for imported vehicles is installed in a domestic vehicle, it is inevitable to use a thick license plate coupling device due to unnecessary nuts. .

The above problem can be solved by simply applying the license plate coupling device without a built-in nut to domestic vehicles, but if the license plate coupling device for license plate protection is divided into domestic vehicles and imported vehicles, unity cannot be provided. , which may cause confusion for consumers. In addition, when the vehicle model is changed from a domestic vehicle to an imported vehicle or vice versa, there is a problem of wasting resources that the license plate coupling device cannot be reused.

In addition, the nut-embedded license plate coupling device can be manufactured by insert injection that performs injection while inserting the nut into the mold after manufacturing the nut of a metal material. In this case, compared to general injection rather than insert injection, the manufacturing process This is complicated, and the production cost is high. Also, if rust or corrosion occurs in the metal nut, the entire license plate coupling device must be replaced.

It is an object of the present invention to propose a license plate coupling device that can be used universally regardless of domestic or imported vehicles.

In particular, the present invention is to propose a license plate coupling device having a smaller thickness than the prior art while having a nut structure that can be fastened with a sealing bolt. Furthermore, the present invention is to propose a structure that can make the thickness of the license plate coupling device thinner than in the prior art, even when the license plate coupling device mountable on imported vehicles is applied to domestic vehicles.

It is an object of the present invention to provide a license plate coupling device of a structure that can be manufactured by a simpler process than the prior art, and can be installed by a simple operation.

An object of the present invention is to propose a license plate coupling device having a structure that can be reused without replacing the entire license plate coupling device when rust or corrosion occurs in a nut made of a metal material.

In order to achieve such an object of the present invention, a vehicle license plate coupling device according to an embodiment of the present invention includes: a base plate mounted on the vehicle; an edge portion protruding along the edge of the base plate to form a license plate accommodating part in which a license plate displaying a vehicle registration number is accommodated together with the base plate; at least one through hole passing through the base plate; and a sealing bolt coupling member mounted on the base plate, wherein the sealing bolt coupling member includes a main body disposed parallel to the base plate, a hole disposed in the main body, and a flange protruding from the periphery of the hole. and a fitting portion into which at least one corner of the main body is fitted is formed on the base plate so that the sealing bolt is fastened through the sealing bolt coupling member, and a thread corresponding to the sealing bolt is formed on the inner circumferential surface of the flange. do.

The flange is a burring part protruding from one surface of the main body by burring, and the thread is a burring tab.

The main body is made of a metal material capable of burring.

The flange is formed at the center of the main body or at a position eccentric to one side from the center.

The fitting portion has a first fitting groove and a second fitting groove disposed on both sides of the through hole, and both edges of the main body are fitted into the first fitting groove and the second fitting groove, respectively, and the flange is the through hole. inserted into the hole.

The through hole is made of a long hole so that the flange is inserted to allow movement of the main body.

The long hole extends along both edges of the main body.

A recess groove is formed on one surface of the base plate, the through hole is disposed at the bottom of the recess groove, and a fitting cover covering at least one corner of the main body is provided at an upper entrance of the recess groove. formed parallel to

A communication hole passing through the base plate and communicating to the rear surface of the base plate is formed at a position facing the fitting cover at the bottom of the recess groove.

At the bottom of the recess groove, limiting protrusions for limiting separation of the main body from the fitting cover protrude from positions spaced apart from the fitting cover, and the limiting protrusions are respectively disposed on both sides of the through hole.

The limiting projection has an inclination in a direction facing the fitting cover and in a direction opposite to the fitting cover, respectively, and the inclination in the direction toward the fitting cover is steeper than the inclination in the direction opposite to the fitting cover.

In addition, the license plate coupling device of the vehicle proposed in the present invention in order to realize the above object, the base plate mounted on the vehicle; an edge portion protruding along the edge of the base plate to form a license plate accommodating part in which a license plate displaying a vehicle registration number is accommodated together with the base plate; a sealing bolt coupling member having a main body formed parallel to the base plate, a hole disposed in the main body and having a thread corresponding to the sealing bolt, and a flange formed at an edge of the hole; a fitting portion disposed on the front surface of the base plate covered by the license plate and formed to fit the main body; and a through hole passing through the base plate and into which the flange is inserted.

According to the present invention of the configuration as described above, by inserting the sealing bolt coupling member into the fitting portion, or by simply withdrawing from the fitting portion, the license plate coupling device can be universally used for both imported and domestic vehicles.

In addition, according to the present invention, the license plate coupling device can implement a thinner thickness than the prior art, while having a function of a nut that can be fastened with a sealing bolt. Through this, various shapes, in particular, it is possible to implement a license plate coupling device that can be mounted on the curved mounting portion. That is, versatility can be expanded.

Specifically, since a thread is formed on the inner circumferential surface of the flange, the sealing bolt coupling device provides a nut function that can be fastened with the sealing bolt.

And a thinner thickness than the prior art is implemented by the license plate coupling device. The conventional nut-built license plate coupling device formed by double injection had no choice but to have a thick overall thickness due to the length of the nut required for solid coupling with the sealing bolt, and the length of the synthetic resin to prevent the nut from being separated.

However, according to the present invention, the plate-shaped main body is fixed by the fitting cover and the recess groove, and the flange is integrally formed with the main body by the burring. When comparing the thickness required to prevent the hollow pillar-shaped nut from being separated with the thickness required to prevent the plate-shaped main body from being separated, the latter is thinner. In addition, an independent structure for preventing separation of the flange integrally formed with the main body is unnecessary.

Due to this, a plate coupling device having a thinner thickness than the prior art can be implemented. In addition, there may be provided a license plate coupling device capable of bending or bending in response to various shapes through this.

In addition, when the license plate coupling device of the present invention is applied to a domestic vehicle, since the sealing bolt coupling device can be excluded, the thickness of the sealing bolt coupling device is not reflected in the license plate coupling device. Therefore, when the license plate coupling device of the present invention is applied to a domestic vehicle, it can be implemented with the same thickness as the license plate coupling device without a built-in nut function.

In addition, according to the present invention, the base plate composed of synthetic resin is formed by injection, and the license plate coupling device composed of metal is formed by burring. Therefore, since the process of double injection is unnecessary, the license plate coupling device can be manufactured in a simplified process than in the prior art.

In addition, according to the present invention, when rust or corrosion occurs in a metal material, it can be easily seen that the rust or corrosion occurs only in the sealing bolt coupling device and not in the base plate. In addition, since the sealing bolt coupling device is a subject that is detachably coupled to the base plate, rust or corrosion problems can be solved only by replacing the sealing bolt coupling device. According to the present invention, there is no need to replace the entire license plate coupling device in order to solve the rust or corrosion problem.

As used herein, the singular expression includes the plural expression unless the context clearly dictates otherwise.

1 is a perspective view showing the use state of the license plate coupling device (CA) of the vehicle 10 proposed by the present invention.

The license plate 110 has a prescribed shape, and must be installed at a designated location. For example, the license plate 110 may be formed in the shape of a rectangular plate, or a rectangular plate with rounded vertices. On the license plate 110 , a vehicle registration number 114 uniquely assigned to each type of vehicle 10 is embossed or engraved.

In addition, the license plate 110 is installed in a designated position of the vehicle 10, for example, the front and rear of the vehicle (10). The license plate 110 is installed to visually expose the vehicle registration number 114 to the front or rear of the vehicle 10 . A license plate mounting unit 15 is formed on the front and rear surfaces of the vehicle 10 , respectively, and the license plate 110 is mounted on the vehicle 10 in a state coupled to the license plate coupling device CA of the vehicle 10 .

The license plate coupling device (CA) is a device for protecting the license plate 110 or installing the license plate 110 to the license plate mounting part 15 of the vehicle 10 . The license plate coupling device (CA) of the vehicle 10 is formed to be coupled with the license plate 110, and is formed to be installed on the vehicle body. The license plate coupling device CA of the vehicle 10 has a slightly larger circumference than the license plate 110 , and is formed to fix the license plate 110 .

In a state in which the license plate coupling device CA is mounted on the license plate mounting unit 15 of the vehicle 10 , the license plate 110 is coupled to the license plate coupling device CA. Then, when the seal 120 is installed, the operation of installing the license plate 110 to the vehicle 10 is completed.

2 is an exploded perspective view of the license plate 110 and the license plate coupling device shown in FIG.

A rectangular plate constituting the license plate 110 may be referred to as a body 112 .

The license plate 110 may have an edge line 116 formed along the edge of the body 112 . The edge line 116 is embossed or engraved along the edge of the body 112 . The border line 116 is formed in a closed curve to surround the vehicle registration number 114 engraved on the license plate 110 . The body 112 of the license plate 110, the vehicle registration number 114, and the edge line 116 may all be integrally formed.

The license plate coupling device includes a base plate 130 . The base plate 130 is mounted on the vehicle 10 , and the license plate 110 is detachably coupled to the base plate 130 . In the operation of installing the license plate 110 to the vehicle 10 , the license plate 110 of the vehicle 10 may be mounted before the base plate 130 is combined with the license plate 110 .

The base plate 130 may have a shape corresponding to the shape of the license plate 110 . For example, the base plate 130 may be formed in a rectangle, or a rectangle with rounded vertices, like the license plate 110 .

The base plate 130 may be implemented with synthetic resin (plastic). However, the present invention is not necessarily limited thereto, and the base plate 130 is not excluded from being formed of a metal or other material.

The base plate 130 may be provided with an information display unit for displaying information such as characters and figures. The information display unit, for example, may be formed to be recessed in the thickness direction of the base plate 130 . Inside the information display unit, for example, a member on which a trade name and/or a logo is displayed may be attached.

The license plate coupling device includes a rim portion 131 protruding along the edge of the base plate 130, and a license plate receiving portion 132 recessed along the thickness direction of the license plate coupling device to accommodate the license plate 110. . Here, the thickness direction refers to the front-back direction of the base plate 130 .

The license plate accommodating part 132 is formed in an area defined by the edge part 131 . When the edge portion 131 protrudes from the edge of the base plate 130, the region corresponding to the license plate receiving portion 132 has a structure that is naturally recessed in the thickness direction. Therefore, it may be understood that the license plate accommodating part 132 is formed as the rim part 131 protrudes, or the rim part 131 is formed as the license plate accommodating part 132 is depressed.

The license plate accommodating part 132 may be recessed into a rectangular shape or a rectangular shape with rounded vertices to correspond to the shape of the license plate 110 , and the license plate 110 is accommodated.

A plurality of through-holes 135 may be formed in the license plate receiving portion 132 so that the fastening elements 161 and 162 coupled to the vehicle 10 may be inserted. The concept of the fastening elements 161 and 162 may include bolts, pins, and the like. When the fastening elements 161 and 162 pass through the base plate 130 and are fastened to the vehicle 10 , the base plate 130 may be fixedly coupled to the vehicle 10 .

The plurality of through-holes 135 may be formed in a greater number than the number of fastening elements 161 and 162 coupled to the vehicle 10 , and their positions are also varied. For example, when the fastening elements 161 and 162 are bolts, the coupling positions of the bolts are different for each type of vehicle 10 , so that the base plate 130 is universally used.

In addition, the plurality of through-holes 135 may be formed of, for example, a long hole having a long length in one side. Thereby, it is possible to appropriately respond to variations in the positions of the fastening elements 161 and 162 . In this way, the base plate 130 may be coupled to the license plate mounting portion 15 of the vehicle 10 using the fastening element.

Next, a structure for coupling the license plate 110 to the base plate 130 coupled to the vehicle 10 will be described.

The edge portion 131 of the base plate 130 or the edge of the license plate accommodating part 132 has a fixing protrusion 133 to prevent the license plate 110 inserted into the license plate accommodating part 132 from being separated. can be formed. The fixing protrusion 133 may be formed to protrude from the edge portion 131 so as to cover one side of the front side of the license plate 110 .

For example, the fixing protrusion 133 may protrude from one side of the edge part 131 toward the other side of the edge part 131 . FIG. 2 shows that the fixing protrusion 133 protrudes from the lower edge of the edge part 131 toward the upper edge. As such, the fixing protrusion 133 may be formed integrally with the edge portion 131 , but the present invention is not necessarily limited thereto.

The fixing protrusion 133 may be formed, for example, on a long side and/or a short side of the license plate accommodating part 132 . Here, the long side refers to one side extending along the longitudinal direction of the license plate accommodating part 132 , and the longitudinal direction refers to a direction formed along a longer edge in the base plate 130 . In FIG. 3 , the longitudinal direction corresponds to the horizontal direction of the license plate accommodating part 132 . On the other hand, the short side portion may be an edge extending along the width direction (or the height direction, or the vertical direction) of the license plate receiving portion 132 .

According to this structure, the lower side of the license plate accommodating part 132 has a side wall of the fixing protrusion 133 and the edge part 131 and a bottom surface of the license plate accommodating part 132 on one side of the license plate 110 . An arrangement space or an insertion space in which this insertion is arranged is formed.

In this way, the fixing protrusion 133 is configured to protrude from the edge portion 131 or coupled to the edge portion 131 or the base plate 130, and to be hooked on one side of the front side of the license plate 110 . In this case, the plurality of fixing protrusions 133 may be formed, and the plurality of predetermined protrusions 133 may be disposed at positions spaced apart from each other in the longitudinal direction.

Meanwhile, the fixing member 150 corresponding to the fixing protrusion 133 is coupled to the base plate 130 . The fixing member 150 is inserted and coupled to the base plate 130 from the opposite side of the fixing protrusion 133 with respect to the license plate receiving part 132 .

A fixing member receiving groove 134 in which the fixing member 150 can be accommodated is formed on the opposite side of the fixing protrusion 133 with respect to the license plate receiving portion 132 . When the fixing member 155 slides within the fixing member receiving groove 134 , the fixing member 150 may be inserted and coupled to the base plate 130 .

At least a portion of the fixing member 150 is formed to protrude so as to overlap the license plate 110 accommodated in the license plate receiving portion (132).

The fixing member 150 is formed to be elastically deformable in the direction pressed by the license plate 110 , and the license plate 110 is restored to its original position the moment it passes the reference point so that the license plate 110 is in close contact with the license plate receiving part 132 . pressure to do

Thereby, after inserting the lower edge of the license plate 110 in the drawing between the bottom surface of the fixing protrusion 133 and the license plate receiving part 132 first, the lower edge of the license plate 110 as a central axis When the upper edge of the license plate 110 is rotated, the fixing member 150 is pressed by the license plate 110 and the license plate 110 passes the reference point at the moment the fixing member 150 is restored to the position before the pressing, and the license plate It is possible to accommodate the license plate 110 in the receiving portion 132 .

After the license plate 110 is inserted into the license plate receiving part 132, the seal 120 and the fastening member 170 are coupled to fix the license plate.

The seal 120 may have a different configuration depending on whether the installation target is a domestic vehicle or an imported vehicle. For example, if the installation target vehicle is a domestic vehicle, the seal 120 is a long type sealing bolt (not shown), a sealing nut (not shown), a washer 122, a pin (not shown) and a sealing cover 123. is composed of

On the other hand, if the installation target vehicle 10 is an imported vehicle, the seal 120 may be composed of a short type sealing bolt 121 , a washer 122 , and a sealing cover 123 , and the pin may be configured in some cases. may optionally be included. In FIG. 2, the structure of the seal 120 for the installation of an imported vehicle is shown.

The license plate 110 has a through hole 118 through which the sealing bolt 121 can pass through is machined at a predetermined position. For example, a through-hole 118 is formed on the left side of the first number where the vehicle registration number 114 starts. The sealing bolt 121 passes through the through hole 118 formed in the license plate 110 and is fastened to the license plate coupling member 140 . On the other hand, the fastening member 170 is inserted into the right through hole 119 of the last number where the vehicle registration number 114 ends.

The license plate coupling member 140 provided in the present invention corresponds to a nut coupled with the short-type sealing bolt 121 . The license plate coupling member 140 is configured to be fitted to the fitting portion 136 of the base plate 130 , and the detailed structure of the license plate coupling member 140 and the fitting portion 136 will be described with reference to FIG. 3 .

3 is a partial enlarged view showing before the sealing bolt coupling member 140 is fitted into the fitting portion 136 of the base plate 130 by sliding movement.

The sealing bolt coupling member 140 includes a main body 141 and a flange 142 . The main body 141 has a flat circular or polygonal plate shape to correspond to the flat base plate 130 . The sealing bolt coupling member 140 is mounted at a predetermined position on the base plate 130 , and at this time, the main body 141 is disposed parallel to the base plate 130 .

A hole H passing through the main body 141 in the thickness direction is formed at the center of the main body 141 or at a position eccentric to one side from the center of the main body 141 . However, the present invention is not limited thereto, and it is also possible to form the hole H in the center of the main body.

And a flange 142 is formed around the hole (H). The flange 142 protrudes in the thickness direction of the main body 141 around the hole H. The outer diameter of the flange 142 is larger than the inner diameter of the hole (H).

If the protrusion length of the flange 142 is excessively thick, it causes an increase in the distance at which the license plate 110 protrudes from the vehicle body. Therefore, the protruding length of the flange 142 should protrude by a smaller length than the nut of the conventional nut-built license plate coupling device. In consideration of this point, the length of the protrusion of the flange 142 is preferably 2.5 times or less of the thickness of the main body 141 .

The flange 142 may be formed by burring the main body 141 in a state in which a hole is not processed. In general, when a plate is penetrated in the thickness direction using a tool called a burring drill or a flow drill, a hole (H) is formed in the plate, and a burr called a burr or a burring part is formed around the hole (H). is formed as a result of The flange 142 corresponds to a burring portion protruding from one surface of the main body 141 by burring.

A thread 143 corresponding to the sealing bolt 121 is formed on the inner circumferential surface of the flange 142 . The thread 143 formed on the inner circumferential surface of the flange 142 corresponds to a burring tab formed by burring. When a burring drill or a flow drill in which a thread is formed on the outer peripheral surface is used to form a burring tab during burring, a thread 143 is naturally formed on the inner peripheral surface of the burring part. At this time, when a precision burring drill or a flow drill is used to form a burring tab of a size that can be screwed with the sealing bolt 121, the inner peripheral surface of the flange 142 has a thread 143 corresponding to the sealing bolt 121. is formed

In order to enable burring, the sealing bolt coupling member 140 may be made of a metal material. However, the present invention is not limited thereto, and the sealing bolt coupling member may be made of a synthetic resin material.

The sealing bolt coupling member 140 having the above structure is mounted at a predetermined position of the base plate 130 . Here, the determined position refers to a position facing the through hole 135 of the license plate 110 in the thickness direction of the base plate 130, and the fitting portion 136 is formed at this position.

The fitting portion 136 formed on the base plate 130 is an area provided for mounting the sealing bolt coupling member 140 , and at least one of the corners of the main body 141 is fitted to the fitting portion 136 .

A recess groove 136a into which the sealing bolt coupling member 140 can be inserted is formed in the fitting portion 136 . The license plate receiving portion 132 of the base plate 130 is formed by being depressed in the thickness direction of the base plate 130 compared to the edge portion 131 , the recessed groove 136a of the fitting portion 136 is the base plate 130 . ) is formed more depressed than the license plate receiving part 132 in the thickness direction.

In order for the main body 141 of the sealing bolt coupling member 140 to slide in the recess groove 136a, the size of the recess groove 136a is larger than the main body 141 of the sealing bolt coupling member 140 . is formed If the horizontal and vertical lengths of the main body 141 and the horizontal and vertical lengths of the recess groove 136a are compared based on the rectangular shape, any one of the horizontal and vertical lengths is similar to each other, but the other is the recess groove 136a. ) is formed to be larger than that of the main body 141 in length.

For example, the vertical length of the main body 141 is slightly smaller than the vertical length of the recess groove 136a. On the other hand, the horizontal length of the recess groove 136a is significantly longer than the horizontal length of the main body 141 . Due to this structure, the main body 141 may slide in the horizontal direction in the recess groove 136a.

The fitting portion 136 includes fitting covers 136b1 and 136b2 that form fitting grooves 136c1 and 136c2. The fitting grooves 136c1 and 136c2 refer to an area in which the main body 141 of the sealing bolt coupling member 140 is fitted. The fitting grooves 136c1 and 136c2 may include a first fitting groove 136c1 and a second fitting groove 136c2 on both sides based on the through hole 136e formed in the recess groove 136a.

The first fitting groove 136c1 and the second fitting groove 136c2 are formed at positions spaced apart from each other in a direction crossing or perpendicular to the sliding direction of the main body 141 in the recess groove 136a. For example, as shown in FIG. 3 , if the main body 141 slides in the horizontal direction in the recess groove 136a, the first fitting groove 136c1 and the second fitting groove 136c2 are the recess grooves 136a. ) are formed at positions spaced apart from each other in the longitudinal direction.

One of the two corners of the main body 141 is fitted into the first fitting groove 136c1, and the other is fitted into the second fitting groove 136c2. Here, the two corners of the main body 141 refer to corners extending along a direction parallel to the sliding direction of the main body 141 . 3 , since the main body 141 slides in the horizontal direction, the two corners indicate two corners extending in the horizontal direction.

The fitting grooves 136c1 and 136c2 are formed by the fitting covers 136b1 and 136b2. The fitting covers 136b1 and 136b2 are formed at the upper inlet of the recess groove 136a. As described above, the recess groove 136a is formed by being depressed in the thickness direction of the base plate 130 , and the starting point of the depression may be an upper entrance of the recess groove 136a. In order for the sealing bolt coupling member 140 to be fitted by sliding movement into the fitting grooves 136c1 and 136c2, it must first be inserted along the thickness direction of the base plate 130 at the point where the recess of the recess groove 136a starts. Therefore, it can be named like this. In addition, the concept of the upper side here is assuming that the depression direction of the recess groove 136a is the depth of the recess groove 136a, the starting point of the depression corresponds to the top in the depth direction of the recess groove 136a. can be derived from

Fitting cover (136b1, 136b2) is formed parallel to the base plate (130). More specifically, the fitting cover (136b1, 136b2) is formed in parallel with the license plate receiving portion 132 of the base plate (130). The fitting cover (136b1, 136b2) protrudes from the license plate receiving part 132 to form one surface with the license plate receiving part 132, and in the thickness direction of the base plate 130, the recess groove (136a) and spaced apart from each other have. Accordingly, fitting grooves 136c1 and 136c2 are formed between the recess groove 136a and the fitting covers 136b1 and 136b2.

Considering that the fitting grooves 136c1 and 136c2 are formed by the fitting covers 136b1 and 136b2, the fitting covers 136b1 and 136b2 are naturally formed at each position where the fitting grooves 136c1 and 136c2 are formed. For example, fitting covers 136b1 and 136b2 are formed at each position where the first fitting groove 136c1 and the second fitting groove 136c2 are formed, and accordingly, the fitting covers 136b1 and 136b2 are respectively attached to the first fitting cover 136b1. ) and the second fitting cover (136b2).

The first fitting cover (136b1) and the second fitting cover (136b2) are formed at positions spaced apart from each other in a direction crossing or perpendicular to the sliding direction of the main body 141 in the recess groove (136a). For example, if the main body 141 slides in the horizontal direction in the recess groove 136a as shown in FIG. 3 , the first fitting cover 136b1 and the second fitting cover 136b2 are recessed grooves 136a ) or is formed in a position spaced apart from each other in the longitudinal direction of the license plate receiving portion (132).

Each fitting cover (136b1, 136b2) covers at least one of the corners of the main body 141 fitted in the fitting groove (136c1, 136c2). As the fitting covers 136b1 and 136b2 cover the edges of the main body 141 in the thickness direction of the base plate 130, the sealing bolt coupling member 140 is arbitrarily separated along the thickness direction of the base plate 130. can be prevented.

A communication hole 136d is formed at a position facing the fitting covers 136b1 and 136b2 from the bottom of the recess groove 136a. The communication hole 136d passes through the base plate 130 and communicates to the rear surface of the base plate 130 . The base plate 130 is manufactured by processing a synthetic resin material by a process called injection, and the communication hole 136d is a structure that occurs naturally in the process of forming the fitting covers 136b1 and 136b2 using the injection process.

In general, injection refers to the process of producing raw materials in a pre-designed shape in a mold by putting raw materials for injection into a mold and applying high heat and high pressure. At this time, in order to separate the mold for processing the object protruding from the recess groove 136a, such as the fitting covers 136b1 and 136b2, from the base plate 130, a hole such as the communication hole 136d must be formed. in need.

The communication hole 136d is formed at a position facing the fitting covers 136b1 and 136b2 in the thickness direction of the base plate 130 . And the shape of the communication hole (136d) is the same as or corresponding to the shape of the fitting cover (136b1, 136b2). The size of the communication hole (136d) is the same as or larger than the size of the fitting cover (136b1, 136b2).

As the first fitting cover (136b1) and the second fitting cover (136b2) are spaced apart from each other in the longitudinal direction of the base plate 130, the two communication holes 136d are also spaced apart from each other in the longitudinal direction of the base plate 130. . And the recess groove 136a is formed between the two communication holes 136d.

It has been described above that a plurality of through-holes penetrating the base plate 130 are formed in the base plate 130 in the thickness direction of the base plate 130. The through-holes 136e are also formed in the recess groove 136a. . The through hole 136e corresponds to a region into which the flange 142 of the sealing bolt coupling member 140 is inserted along the thickness direction of the base plate 130 . Accordingly, the inner diameter of the through hole 136e should be equal to or greater than the outer diameter of the flange 142 .

Since the flange 142 protrudes from one surface of the main body 141, when the main body 141 is inserted into the recess groove 136a, the flange 142 naturally forms the through hole ( 136e). The through hole 135 is formed of a long hole through which the flange 142 is inserted to allow movement of the main body 141 .

The through hole 136e should be formed to allow sliding movement of the flange 142 according to the sliding movement of the main body 141 . Therefore, the long hole has a shape that extends long along the direction in which both edges of the main body 141 extend so as to enable sliding movement of the main body 141 and the flange 142 .

Here, both corners refer to two corners fitted into the fitting grooves 136c1 and 136c2 of the fitting part 136 . The two corners extend along the horizontal direction corresponding to the sliding movement direction of the main body 141, and the long hole also extends along the horizontal direction corresponding to the sliding movement direction of the main body 141 and the flange 142. has

If the through hole (136e) is made of a long hole, the flange 142 is not located in the center of the main body 141, it is also possible to be formed at an eccentric position from the center of the main body 141 to one side. For example, even if it is eccentric in the sliding movement direction of the main body 141, the original function of the sealing bolt coupling member 140 is not affected. Therefore, the long hole gives a degree of freedom in design in manufacturing the sealing bolt coupling member 140 .

A limiting protrusion 136f is formed on the bottom of the recess groove 136a to limit the arbitrarily detaching of the main body 141 fitted in the fitting grooves 136c1 and 136c2 from the fitting grooves 136c1 and 136c2. The limiting protrusion 136f protrudes from the bottom of the recess groove 136a toward the front of the base plate 130 .

The limiting protrusion 136f may have an inclination. The slope is formed in the direction facing the fitting groove (136c1, 136c2) and the opposite direction. The two slopes are formed at positions facing opposite to each other in the sliding direction of the main body 141 .

The angles of the two slopes may be different from each other. For example, in the process in which the main body 141 is fitted into the fitting grooves 136c1 and 136c2, an inclination formed in a direction opposite to the fitting grooves 136c1 and 136c2 is in contact with one surface of the main body 141. Since the main body 141 is preferably inserted by a smooth movement in the process of being fitted into the fitting grooves 136c1 and 136c2, the inclination in contact with the main body 141 is preferably gentle.

On the other hand, after the main body 141 is fitted into the fitting grooves 136c1 and 136c2 , the inclination formed in the direction toward the fitting grooves 136c1 and 136c2 comes into contact with the main body 141 . After the main body 141 is fitted into the fitting grooves 136c1 and 136c2, it is necessary to limit the departure of the main body 141 through an abrupt inclination, so the angle of the inclination formed in the direction toward the fitting grooves 136c1 and 136c2 is Abrupt is preferable.

Therefore, the slope formed in the direction toward the fitting groove (136c1, 136c2) or the fitting cover (136b1, 136b2) of the two slopes of the limiting projection (136f) toward the fitting groove (136c1, 136c2) or the fitting cover (136b1, 136b2) toward the steeper than the slope formed on the opposite side of the direction.

The limiting protrusion 136f protrudes at a position spaced apart from the fitting covers 136b1 and 136b2. The separation direction between the limiting protrusion 136f and the fitting covers 136b1 and 136b2 is the thickness direction of the base plate 130 . The limiting protrusion 136f limits the departure of the main body 141 and should not prevent the sliding movement of the main body 141 . Therefore, the limiting protrusion (136f) should be spaced apart from the fitting cover (136b1, 136b2), so that the main body 141 can slide therebetween.

The limiting protrusions 136f are respectively disposed on both sides of the through hole 135 . Both sides of the through hole 135 refer to one side and the opposite side of the long hole in a direction crossing or orthogonal to the sliding movement direction of the main body 141 . Referring to FIG. 3 , it may be understood that the communication holes 136d described above are also formed on both sides of the long hole.

4 is a partial enlarged view showing after the sealing bolt coupling member 140 is fitted into the fitting portion 136 of the base plate 130 by sliding movement.

FIG. 5 is a cross-sectional view corresponding to a position A-A shown in FIG. 4 .

When the sealing bolt coupling member 140 is inserted into the fitting portion 136 of the base plate 130 , both edges of the main body 141 are fitted with the fitting covers 136b1 and 136b2 in the thickness direction of the base plate 130 and the communication hole. It is located between (136d). Accordingly, in the thickness direction of the base plate 130, the fitting covers 136b1 and 136b2, both edges of the main body 141, and the communication hole 136d overlap each other.

The hole (H) of the sealing bolt coupling member 140 is disposed between the first fitting cover (136b1) and the second fitting cover (136b2). And the flange 142 slides in the long hole, and maintains the inserted state in the long hole. Referring to FIG. 5 , the flange 142 may have a length that protrudes further to the rear of the base plate 130 than the long hole for solid fastening with the sealing bolt 121 .

Arbitrary movement of the sealing bolt coupling member 140 fitted in the fitting portion 136 is limited by the shape of the recess groove 136a, the limiting protrusion 136f, and the fitting covers 136b1 and 136b2. First, the longitudinal movement of the base plate 130 is limited by a structure in which the longitudinal length of the recess groove 136a is substantially equal to the longitudinal length of the main body 141 or slightly larger than that. And the horizontal movement of the sealing bolt coupling member 140 is limited by the inclination of the limiting projection (136f). Finally, the movement of the sealing bolt coupling member 140 in the thickness direction of the base plate 130 is limited by the fitting cover (136b1, 136b2) and the recess groove (136a).

Accordingly, the sealing bolt coupling member 140 can be fixed at a designated position, the sealing bolt 121 screwed to the sealing bolt coupling member 140, and the washer 122 coupled to the sealing bolt 121. And the sealing cover 123 may be fixed at a designated position.

When the seal 120 is to be installed without a seal nut like the imported vehicle 10 , the seal bolt coupling member 140 is essential. Therefore, the fitting portion 136 of the base plate 130 must be fitted with the sealing bolt coupling member 140 in advance.

On the other hand, when the sealing nut is disposed inside the vehicle body as in the domestic vehicle 10, the sealing bolt coupling member 140 is unnecessary. Therefore, when installing the license plate 110 and the seal 120 in the domestic vehicle 10, the sealing bolt coupling member 140 is pulled out from the fitting part 136, and the fitting part 136 is emptied, and the seal 120 ) is installed. In this case, since the protruding length of the flange 142 is eliminated, the thickness of the license plate coupling device 140 may be reduced and the license plate 110 may be disposed closer to the vehicle body.

In addition, according to the present invention, by simply inserting the sealing bolt coupling member 140 into the fitting part 136 or withdrawing it from the fitting part 136, the license plate coupling device 140 is installed in the imported vehicle 10 and the domestic vehicle. (10) It can be used universally for all.

The license plate coupling device of the vehicle described above is not limited to the configuration and method of the embodiments described above, the embodiments may be configured by selectively combining all or part of each embodiment so that various modifications can be made. have.
