BACKGROUND

1. Technical Field

The present disclosure relates to a locking module and a locking module attachment device including the locking module, and more particularly, to a locking module that is attached to a product whose part is selectively spaced apart from the rest of the product and disposed close to the rest of the product and provides a fastening function, and a locking module attachment device including the locking module.

2. Description of the Related Art

Recently, as small portable wireless earphones have been released on the market and are popularly used, charging cases that can safely store wireless earphones and charge the wireless earphones are also sold together with the wireless earphones.

However, conventional charging cases on sale have a problem in that wireless earphones are lost or damaged as the wireless earphones are separated from a charging case when the lid of the charging case is opened by impact. In the case where a separate case covering a charging case is employed, there is a disadvantage in that the aesthetics of the design of a product decreases as the volume and weight of the product increase.

In addition, in the case of cases used for various products as well as cases used for electronic products such as smartphones and tablets, a lid may be easily separated by external impact in a state in which the inner space of a case is sealed with the lid. Accordingly, there is a demand for a technology for improving the fixing force of a lid by adding a separate device for fixing the lid within the range without damaging the exterior of the case.

In connection with this, Korean Patent No. 10-2355920 entitled “Functional Wireless Earphone Case” discloses a technology for improving the fixing force of the lid of a charging case by being coupled to the charging case in a form surrounding the overall charging case for wireless earphones. Korean Patent No. 10-2345619 discloses a “Wireless Earphone Cradle Case Accessory Providing User Convenience.”

However, conventional technologies do not disclose a technology for improving the fixing force of a lid while suppressing an increase in the volume and weight of a product case itself.

DETAILED DESCRIPTION

The configurations, operations and effects of a locking module and a locking module attachment device including the locking module according to embodiments will be described below with reference to the accompanying drawings. For reference, in the accompanying drawings, each component is omitted or schematically illustrated for convenience and clarity of description, and the size of each component does not reflect the actual size thereof. Furthermore, like reference numerals denotes like components throughout the present specification, and some reference numerals for like components may be omitted in each of the drawings.

As shown in FIGS. 1 to 9, a locking module attachment device 100 includes a locking module 200, a first adhesive member 310, a second adhesive member 320, a first protective member 330, a jig 400, and a second protection member 600.

The locking module attachment device 100 is used to rapidly, accurately, and conveniently attach the locking module 200 to a specific position of a product 10 in which an electronic product such as wireless earphones is stored and charged.

The product 10 includes a first body 11 and a second body 12. The second body 12 is detachably coupled to or detached from the first body 11 through rotation to seal the electronic product stored therein from the outside or to open it to the outside.

The electronic product is accommodated only in either the first body 11 or the second body 12. Alternatively, the electronic product may be accommodated in the product 10 in such a manner that a part of the electronic product is stored in the first body 11 and the rest of the electronic product is stored in the second body 12.

In a state in which the first and second bodies 11 and 12 are in close contact with each other to seal the space inside the product 10, the top surfaces of the first and second bodies 11 and 12 are connected to each other to form a flat surface.

A top groove 13 is formed by depressing portions of the top surfaces of the first and second bodies 11 and 12 extending to both sides in a state in which the first and second bodies 11 and 12 are in close contact with each other. The top groove 13 is used to detach the second body 12 from the first body 11.

Meanwhile, the first and second bodies 11 and 12 may be coupled by moving through sliding rather than rotation. The first and second bodies 11 and 12 may have a structure that exposes the electronic product to the outside in the state of being coupled to each other. The first and second bodies 11 and 12 may be connected to each other so that they can be moved to be selectively spaced apart from each other and disposed close to each other.

Although the product 10 disclosed in FIG. 1 is a charging case used for wireless earphones, the product 10 may include a foldable terminal, a case product with a lid, and a case product with a sliding door.

More specifically, the product 10 may be formed in any one of a structure including first and second bodies that are rotatably coupled to each other, a structure including first and second bodies that are slidably coupled to each other, and a structure including first and second bodies that are separate from each other but are selectively brought into close contact with each other and spaced apart from each other through a separate bracket.

The locking module 200 includes first and second locking units 220 and 240 that are separate from each other. The first and second locking units 220 and 240 are attached to the top surfaces of the first and second bodies 11 and 12, respectively.

In a state in which the locking module 200 is attached to the product 10, when the second body 12 is rotated and spaced apart from the first body 11, the first and second locking units 220 and 240 detachably coupled to each other are detached from each other, and the electronic product is exposed to the outside.

In a state in which the locking module 200 is attached to the product 10, when the second body 12 is rotated and moved to a position adjacent to the first body 11, the first and second locking units 220 and 240 are fastened to each other, and the electronic product is safely stored inside the product 10 by the combination of the first and second bodies 11 and 12 through the locking module 200.

The first adhesive member 310 is formed in a shape in which one side and the other side of a central portion formed in the shape of a film extending to both sides are vertically bent toward the front. The top surface of the first adhesive member 310 is attached to the bottom surface of the first locking unit 220.

The first adhesive member 310 is attached to the top surface located in the front and center of the first body 11 in a state of being separated from the first protective member 330 attached beneath it, thereby firmly attaching the first locking unit 220 to the first body 11.

The second adhesive member 320 is formed in a shape in which portions of one side and the other side of a central portion formed in the shape of a film extending to both sides are vertically bent toward the rear. The top surface of the second adhesive member 320 is attached to the bottom surface of the second locking unit 240.

The second adhesive member 320 is attached to the top surface located in the rear and center of the second body 12 in a state of being separated from the first protective member 330 attached underneath it, thereby firmly attaching the second locking unit 240 to the second body 12.

Accordingly, the first and second adhesive members 310 are attached to the bottom surfaces of the first and second locking units 220 and 240, respectively, and are used as adhesive members for attaching the product 10 and the first and second locking units 220 and 240 to each other at the bottoms of the first and second locking units 220 and 240.

In a state in which the first and second bodies 11 and 12 come into close contact with each other and seal the product 10, the first and second adhesive members 310 and 320 are disposed at adjacent positions to be spaced apart from each other, and the overall shape is formed in the shape of a rectangular ring with corners tapered.

One end of the first protective member 330 is formed in the shape of a rectangular film with corners tapered in an arc shape, and the top surface of the one end of the first protective member 330 is easily detachably attached to the bottom surface of the first and second adhesive members 310 and 320. The other end of the first protective member 330 extends from the center of the front of one end toward the front by a predetermined distance in a rectangular shape smaller than that of the one end.

When the other end of the first protective member 330 is moved downward while being held with one hand, one end of the first protective member 330 is separated from the first and second adhesive members 310 and 320, and the adhesive bottom surfaces of the first and second adhesive members 310 and 320 are exposed to the outside.

The bottom surface of one end of the jig 400 is detachably coupled to the locking module 200 in a state of being in close contact with the top surface of the locking module 200. The other end of the jig 400 is formed to extend downward from the edge and surround the product 10.

One end of the second protective member 600 is formed in the shape of a rectangular film with corners tapered in an arc shape, and the bottom surface of the one end of the second protective member 600 is attached to the top surface of one end of the jig 400 and a portion of the top surface of the locking module 200. The other end of the second protective member 600 extends from the front center of the one end toward the front by a predetermined distance in a rectangular shape smaller than that of the one end.

Referring to FIGS. 1 and 9, in the process of attaching the locking module 200 to the product 10 through the locking module attachment device 100, the first protective member 330 is separated from the locking module attachment device 100 and lowered toward the product 10, the first and second adhesive members 310 and 320 are attached to the product 10, and the locking module 200 is attached to the product 10 through the first and second adhesive members 310 and 320.

In a process in which the locking module 200 and the jig 400 are lowered and the locking module 200 is attached to the product 10, a portion of the inner surface of the jig 400 is lowered while being in close contact with the product 10, and thus guides the locking module 200 to a specific position located on the top of the product 10.

A portion of the locking module 200 is attached to the top surface of the first body 11 adjacent to a first opening through which a first space inside the first body 11 is connected to the outside, and the rest of the locking module 200 is attached to the top surface of the second body 12 adjacent to the first opening in a separated state.

More specifically, the bottom surface of the first locking unit 220 is attached to the top surface of the first body 11 through the first adhesive member 310, and the bottom surface of the second locking unit 240 is attached to the top surface of the second body 12 through the second adhesive member 320.

The locking module 200 is pressed downward through the second protective member 600, and the second protective member 600 is detached from the locking module 200 in a state in which the locking module 200 is firmly attached through the first and second adhesive members 310 and 320.

When the jig 400 is moved upward from the locking module 200 and the product 10 in a state in which the second protective member 600 is detached from the locking module 200, the jig 400 is detached from the locking module 200, and the locking module 200 is accurately attached to a specific position of the product 10.

Referring to FIGS. 2 to 5, the locking module 200 includes the first locking unit 220 and the second locking unit 240. The first locking unit 220 includes a first fixing member 222, a first fastening member 224, and a first protrusion 226, and the second locking unit 240 includes a second fixing member 242, a second fastening member 244, and a second protrusion 246.

One end of the first locking unit 220 is formed in a shape in which portions of both sides of the center thereof are bent forward. The other end of the first locking unit 220 extends in a plate shape by a predetermined distance forward from the center of the one end, and a portion of the other end protrudes upward and is detachably coupled with the second locking unit 240.

More specifically, the first fixing member 222 is formed such that portions of one side and the other side of the center thereof are vertically bent toward the front and surround both sides and rear of a deformation space 5. The upper portion of the outer edge of the first fixing member 222 is tapered and forms a first inclined surface 222a. A first side surface 222b is formed beneath the first inclined surface 222a.

In the center of the rear surface of the first side surface 222b, a portion is depressed forward and forms a first groove 222c. At positions in front of one side and the other side of the first side surface 222b, portions of the one side and the other side of the first side surface 222b are depressed and form second and third grooves 222d and 222e, respectively.

One end of the first fastening member 224 is formed in the shape of a rectangular plate with corners formed in an arc shape, and is elastically and vertically movably coupled to the top portion of the center of the first fixing member 222. The other end of the first fastening member 224 extends forward by a predetermined distance in a state in which both side surfaces thereof are spaced apart from the first fixing member 222 in the deformation space 5.

Both side surfaces of the first fastening member 224 are spaced apart from one side and the other side of the first fixing member 222 located on both sides with the side grooves 224a and 224b shown in FIG. 4 interposed therebetween, in the deformation space 5.

Referring to FIGS. 2, 3 and 5, one end of the first protrusion 226 extends forward and downward by a predetermined distance from the bottom of the other end of the first fastening member 224. The other end of the first protrusion 226 is bent and extends upward from the one end and surrounds a first catch groove formed in the top.

One end of the second locking unit 240 is formed in a shape in which portions of both sides of the center thereof are bent rearward. The other end of the second locking unit 240 is formed in a plate shape connecting the inner surface of the rear of the one end, and a portion of the other end of the second locking unit 240 protrudes downward and is detachably coupled to the other end of the first locking unit 220.

When one ends of the first and second locking units 220 and 240 are attached to the first and second bodies 11 and 12 through the pressing and guiding of the jig 400, the one ends of the first and second locking units 220 and 240 are connected to each other and formed in a shape surrounding the deformation space 5.

More specifically, the second fixing member 242 is formed such that portions of one side and the other side of the center thereof are vertically bent toward the rear. The upper portion of the outer edge of the second fixing member 242 is tapered and forms a second inclined surface 242a. A second side surface 242b is formed beneath the second inclined surface 242a.

Due to the shape of the second fixing member 242, the bottom surface of the second fixing member 242 is stably attached to the top surface of the second body 12 while surrounding a portion in front of the top groove 13. In this case, there is an advantage in that the fastening force between the first and second fastening members 224 and 244 is strengthened.

A portion of the second side surface 242b is depressed in the center of the front of the second side surface 242b and forms a fourth groove 242c. Portions of one side and the other side of the second side surface 242b are depressed on the rears of the one side and the other side of the second side surface 242b, respectively, and form fifth and sixth grooves 242d and 242e, respectively.

One end of the second fastening member 244 is formed in a plate shape and connected to the rear and top of the second fixing member 242. The other end of the second fastening member 244 extends from the one end to positions corresponding to the rear surfaces of one side and the other side of the second fixing member 242 while maintaining a state in which both side surfaces are connected to the inner surface of the rear of the second fixing member 242.

The second protrusion 246 protrudes downward from the other end of the second fastening member 244 by a predetermined distance and surrounds the second catch groove formed in the front. In a state in which the first and second locking units 220 and 240 are fastened to each other, the second protrusion 246 is inserted into the first catch groove. The first protrusion 226 is inserted into the second catch groove.

When the bottom surfaces of the first and second fixing members 222 and 242 are coupled to the top surfaces of the first and second bodies 11 and 12 through the pressing and guiding of the jig 400, the first and second fixing members 222 and 242 are formed to be connected to each other and surround the deformation space 5 in a rectangular shape with corners tapered in an arc shape.

Since the first and second fixing members 222 and 242 surround the deformation space 5, there are advantages in that foreign materials are prevented from penetrating into the deformation space 5, the first fastening member 224 moves smoothly up and down in the deformation space 5 regardless of the environment in which the product 10 is located, and the engagement or separation between the first and second fastening members 224 and 244 is stably performed.

Referring to FIGS. 5 and 9, in a state in which the second body 12 is rotated and coupled to the first body 11, the top surfaces of the first and second bodies 11 and 12 are arranged on the same horizontal line, and the first and second protrusions 226 and 246 are coupled to each other in a protrusion engagement manner over the first and second bodies 11 and 12.

In a state in which the first and second bodies 11 and 12 are brought into close contact with each other and coupled to each other, a portion of the bottom surface of the rear of the first fixing member 222 is attached to the center of the top of the first body 11, and the first protrusion 226 is coupled with the second protrusion 246 in a protrusion engagement manner over the second body 12 and is disposed spaced apart from each other over the first and second bodies 11 and 12.

Referring to FIG. 5, in a state in which the first and second bodies 11 and 12 are brought into close contact with each other and coupled to each other, a portion of the bottom surface of the front of the second fixing member 242 is attached to the center of the top of the second body 12, the second protrusion 246 is engaged with the first protrusion 226 over the second body 12, and the front-rear thickness of the second fixing member 242 is formed to be smaller than the front-rear thickness of the first fixing member 222.

Referring to FIGS. 4 and 9, in a state in which the first and second bodies 11 and 12 are brought into close contact with each other and coupled to each other, the top surfaces of the first and second fixing members 222 and 242 are connected to each other and formed in the shape of a rectangular frame with corners tapered in an arc shape. Accordingly, there is an advantage in that the human body is prevented from being damaged.

In a state in which the first and second bodies 11 and 12 are brought into close contact with each other and coupled to each other, the first inclined surface 222a and the second inclined surface 242a are formed to be connected to each other and surround the deformation space 5.

Referring to FIGS. 5 and 9, the first fastening member 224 is lowered to separate the first protrusion 226 from the second protrusion 246. When the second body 12 is moved forward and downward around a lower rotation shaft 12a formed at the bottom of the second body 12, the inside of the product 10 is opened.

Conversely, in a state in which the inside of the product 10 is opened, when the second body 12 is brought into close contact with the first body 11 by moving the second body 12 rearward and upward around the lower rotation shaft 12a, the second protrusion 246 is moved rearward while pushing the upper inclined surface formed on the top of the first protrusion 226 downward, and is coupled with the first protrusion 226 while being inserted into the first catch groove.

Referring to FIGS. 1 to 7, the jig 400 includes a pressing part 410, a jig body 420, and a guide part 430.

One end of the jig 400 is formed in a shape surrounding the edge of the locking module 200, and the bottom surface of the jig 400 comes into close contact with the top of the edge of the locking module 200. The other end of the jig 400 extends outward and downward from the outside of the one end, is formed in the shape of a rectangular tube with corners tapered, and surrounds the locking module 200, the first adhesive member 310, the second adhesive member 320, the first protective member 330, and the product 10.

Referring to FIGS. 2, 3, 5 and 6, the pressing part 410 includes a side support member 411, an inclined surface pressing member 412, a first projection 413, a second projection 414, and third projections 415, 416, 417, and 418.

One end of the pressing part 410 is formed in a rectangular ring shape having outer corners tapered and surrounding a first hollow 1. The other end of the pressing part 410 extends by a predetermined distance while the thickness of the upper and lower portions decreases toward the first hollow 1 from the top of the one end, so that a lower inclined surface is formed on the inside thereof.

More specifically, referring to FIG. 5, the side support member 411 is formed in the shape of a rectangular ring surrounding the first hollow 1, and comes into close contact with the first and second side surfaces 222b and 242b in a state in which the locking module 200 and the jig 400 are coupled to each other.

The inclined surface pressing member 412 extends by a predetermined distance while the upper-lower thickness thereof decreases toward the first hollow 1 over the side support member 411, so that the sectional shape thereof is formed in a triangular shape. Accordingly, the lower inclined surface facing the first hollow 1 and being in close contact with the first and second inclined surfaces 222a and 242a is formed.

In a state in which the locking module 200 and the jig 400 are lowered such that the first and second adhesive members 310 and 320 come into close contact with the first and second bodies 11 and 12, respectively, the lower inclined surface presses the first and second inclined surfaces 222a and 242a. Accordingly, the attaching force between the first and second fixing members 222 and 242 and the first and second bodies 11 and 12 is strengthened.

Referring to FIGS. 2, 3, 5, 6 and 7, the first protrusion 413 is formed to protrude in a hemispherical shape forward from the inner surface of the center of the rear of the side support member 411 (the rear of the first hollow 1). In a state where the locking module 200 and the jig 400 are coupled to each other, the first protrusion 413 is inserted into the first groove 222c.

Referring to FIG. 6, the second protrusion 414 is formed to protrude in a hemispherical shape rearward from the inner surface of the center of the front of the side support member 411 (the front of the first hollow 1). In a state in which the locking module 200 and the jig 400 are coupled to each other, the second protrusion 414 is inserted into a fourth groove 242c (shown in FIG. 2) formed in the front of the second fixing member 242.

Referring to FIG. 6, the third protrusion 416 is formed to protrude in a hemispherical shape from the inner surface of one side of the side support member 411 on the front of the third protrusion 415 toward the other side. In a state in which the locking module 200 and the jig 400 are coupled to each other, the third protrusion 416 is inserted into the fifth groove 242d (shown in FIG. 2) of the second fixing member 242.
