In addition, in the step of printing the electrical wiring, the thickness of the electrical wiring may be adjusted with respect to a region in which the plan view is contracted, relaxed, or bent.

In addition, the printing of the electrical wiring may include printing a plurality of electrical wirings printed in an area in which the planar drawing is contracted, relaxed or bent, spaced apart from each other, and when the planar drawing is contracted, relaxed, or bent, the shrinkage Alternatively, a plurality of printed electrical wirings spaced apart from each other in the relaxed or bent region may be connected to each other.

In addition, in the printing of the electrical wiring, the electrical wiring is printed on at least one of both surfaces of the plan view, so that the electrical wiring is printed on at least one of an outer surface and an inner surface of the outer case.

In addition, the printed electrical wiring has heat resistance to the heat treatment performed on the plan view.

Hereinafter, the present invention will be described in more detail with reference to the drawings. And, in describing the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted. And, the terms to be described later are terms defined in consideration of functions in the present invention, which may vary depending on the intention or relationship of a user or an operator. Therefore, the definition should be made based on the content throughout this specification.

1A and 1B are views illustrating a smart helmet and the inside of the smart helmet according to an embodiment of the present invention.

1A and 1B , the smart helmet 100 according to an embodiment of the present invention includes an outer case 110 and an inner case 120 . Here, electronic components such as the microphone unit 111 and the button manipulation unit 112 may be inserted into the smart helmet 100 .

And, the outer case 110 includes the printed electrical wiring 113 . The printed electrical wiring 113 refers to an electrical wiring printed on the inner surface of the outer case 110 .

In addition, the inner case 120 includes the electronic components 111 and 112, and is injection-molded with a filler for cushioning impact. Here, when the electric wiring 113 is printed on the inner surface of the outer case 110 to form the helmet by injecting the inner case material, that is, the filler or EPS, there is no need to separately fix the electric wire inside the helmet, and artificial manipulation is not required. In this way, it is possible to avoid the problem of low fixing efficiency by fixing the lower part of the wire directly to the outer case. In addition, when the inner case material is injected and injection molded, it is possible to avoid that the electric wire moved under the influence of pressure and temperature is exposed out of the outer case, affecting the aesthetics and quality of the product.

Therefore, due to the electrical wiring 113 being printed on the outer case 110, the electric wire is exposed outside the outer case 110, or when the inner case material is injected, the electric wire is peeled off or the electric wire is broken due to problems such as contact It is possible to reduce the defect rate by solving the problem of defects occurring.

On the other hand, the printed electrical wiring 113 may perform an electrical connection between the microphone unit 111 and the button operation unit 112, and, like the printed electrical wiring 114 shown in FIG. 1B , within the outer case 110 . It can be printed in various forms at various locations.

The printed electrical wiring may be changed in design according to the design of the outer case 110 , the type of electronic component inserted into the smart helmet 100 , and the arrangement position.

2A is a diagram illustrating electrical wiring printed inside an outer case according to an embodiment of the present invention.

Referring to FIG. 2A , the inside of the outer case 110 is shown, and the inside of the outer case 110 varies according to the design of the outer case 110 and the arrangement position of electronic components inserted into the smart helmet 100 . Electrical wiring 114 , 115 , 116 may be printed in place.

For example, in the case of a bicycle helmet, the design of the outer case 110 may include a plurality of openings for wind flow and ventilation. can be printed.

Alternatively, electrical wires 114 , 115 , and 116 may be printed in consideration of positions of a microphone, a speaker, a manipulation unit, a charging port, etc. inserted into the smart helmet 100 .

Meanwhile, the printed electrical wiring according to an embodiment of the present invention may include a flexible printed circuit board (FPCB).

2B is a diagram illustrating a flexible printed circuit board (FPCB) according to an embodiment of the present invention.

Referring to FIG. 2B , the flexible printed circuit board 200 is flexible, light and thin, and thus can be easily bent or folded. In addition, due to the characteristics of raw materials, heat resistance, bending resistance, chemical resistance, etc. are excellent, and the thermal deformation rate is small.

Accordingly, when most curved surfaces such as helmets are used, it is more efficient to directly print circuits on the helmet using the flexible printed circuit board 200 rather than attaching wires to the surface of the outer case 110 one by one and artificially fixing them. And the fixing force and adhesion of the electric wiring to the outer case 100 are excellent.

3 is a diagram illustrating a method of manufacturing a smart helmet according to an embodiment of the present invention.

Referring to FIG. 3 , in the method of manufacturing a smart helmet according to an embodiment of the present invention, a plan view corresponding to the outer case of the smart helmet is printed ( S310 ), and an electrical connection between electronic components inserted into the smart helmet on the plan view is performed.

Here, the step (S310) of printing a planar drawing corresponding to the outer case of the smart helmet is processed in the form of a three-dimensional outer case from a planar drawing by later heat treatment, and for this purpose, a planar drawing corresponding to the three-dimensional outer case It is printed on a flat panel made of polycarbonate (PC), which is a material constituting this outer case.

Polycarbonate, which is a material of the outer case, is suitable for molding the outer case by performing heat treatment from a plan view because it is strong in impact, chemical, and rigid in a wide temperature range and has good workability.

Most of these polycarbonate flat panels have a thickness of 0.5 mm to 1 mm, and a planar drawing corresponding to the outer case may be printed on one surface of the polycarbonate flat panel. Specifically, it will be described with reference to FIG. 4 .

4 is a view showing a plan view for an outer case according to an embodiment of the present invention.

Referring to FIG. 4 , a plurality of planar drawings 410 , 420 , 430 , 440 , 450 and 460 are printed on the flat panel 400 , and a plurality of planar drawings 410 , 420 , 430 , 440 , 450 , 460 are printed. ) each corresponds to each of the outer cases.

In addition, each of the plurality of plane drawings 410 , 420 , 430 , 440 , 450 , and 460 may be implemented in different shapes and colors according to the color or design of the outer case.

Also, for example, a three-dimensional outer case 470 may be formed by performing heat treatment as described above with respect to the plan view 440 .

And, for each of the plurality of flat drawings (410, 420, 430, 440, 450, 460) printed on the flat panel 400, the step of printing an electrical wiring for electrical connection between the electronic components inserted into the smart helmet is is performed (S320).

Here, the printed electrical wiring may be changed in design according to the design of the outer case, the type and arrangement position of the electronic component inserted into the smart helmet.

That is, according to the design of the outer case corresponding to each of the plurality of planar drawings 410, 420, 430, 440, 450, and 460, that is, the planar drawings 410, 420, 430, 440 according to changing factors such as the number and position of openings. , 450, 460), the length, width, position, etc. of the electrical wiring printed on each may be changed.

In addition, since the printed electrical wiring supports the electrical connection of the electronic component inserted into the smart helmet, it is in each of the plan drawings (410, 420, 430, 440, 450, 460) according to the arrangement position of the electronic component inserted into the smart helmet. The length, width, position, etc. of the printed electrical wiring may be changed. It will be described in more detail with reference to FIG. 5 .

5 is a view showing electrical wiring printed on a plan view for an outer case according to an embodiment of the present invention.

Referring to FIG. 5 , on one plan view 410 of a plurality of plan views 410 , 420 , 430 , 440 , 450 , and 460 printed on the flat panel 400 shown in FIG. 4 , Various electrical wirings (510, 520, 530, 540) are printed, taking into account placement locations (411-1, 411-2, 411-3, 411-4, 411-5) and enabling electrical connection of each electronic component. has been

These various electrical wirings 510, 520, 530, and 540 are printed on the plan view 410 corresponding to the three-dimensional outer case, and should be printed in consideration of the area to be contracted or relaxed through subsequent heat treatment, which will be described later. do it with

For example, an electrical wire 510 electrically connecting the position 411-1 of the microphone and the position 411-4 of the charging port on the plan view 410 corresponding to the outer case may be printed, and the right Electrical wiring 520 connecting the position 411-2 of the speaker and the position 411-4 of the charging port may be printed, the position of the left speaker 411-3 and the position of the charging port 411-4 ) may be printed with electrical wiring 530 connecting them.

In addition, an electrical wiring 540 connecting the position 411-3 of the left speaker and the position 411-5 of the button manipulation unit may be printed.

Meanwhile, the printed electrical wiring according to an embodiment of the present invention has been described above as including a flexible printed circuit board (FPCB), and various electrical wirings 510, 520, The process of printing 530 and 540 is similar to that of the flexible printed circuit board.

For example, in the flexible printed circuit board process, the guides required for the process and the by-hole for energization are processed (drilling step), and copper is plated on the surface and the inner wall of the by-hole to energize the circuit (copper plating step), and then dry Process with a brush (front step) to improve film adhesion and remove burrs, adhere dry film of the product using heat and pressure (dry film step), and irradiate UV to form a circuit on dry film ( exposure step), a circuit is completely formed (etching step) through the processes of development, etching, and peeling, and a coverlay is attached (C/L temporary bonding step) to protect the circuit, and then the temporarily attached coverlay is heated and pressure is added and completely compressed (hot press step).

Among the above-described flexible printed circuit board processes, various electrical wirings 510, 520, 530, 540) can be printed.

That is, in printing the electric wiring 510 on the plan view 410 , copper is plated on the surface to conduct electricity at the position where the electric wiring 510 is to be printed, and after processing with a brush, a flat surface using heat and pressure. Close the dry film to the drawing 410, irradiate UV to form the electrical wiring 510 on the dry film, and then completely form the electrical wiring 510 through the process of development, etching and peeling, and the formed electrical wiring 510 ), by attaching a coverlay to protect it and compressing it by applying heat and pressure, the electrical wiring 510 can be printed on the plan view 410 .

In addition, the flexible printed circuit board process includes a step of plating gold on the surface to prevent oxidation of the product and improving solderability, a printing step of machining a guide hole required for external processing, etc., and these processes are also of the present invention. It may be utilized to print various electrical wirings 510 , 520 , 530 , and 540 on the plan view 410 according to an embodiment.

On the other hand, in a state in which various electrical wirings 510, 520, 530, 540 are printed on the plan view 410, heat treatment is performed on the plan view 410 to form the outer case of the smart helmet (S330) ).

Specifically, the ductility of the flat panel 400 printed with the flat drawing 410 is increased by heat treatment at a predetermined temperature for the flat drawing 410 for a predetermined time, thereby making processing easier, and utilizing a mold or pressure. Thus, the planar drawing 410 with increased ductility is formed in the form of an outer case.

Then, the formed outer case is separated from the plan view 410 (S340). Specifically, the outer case formed through a laser, a diamond knife, etc. may be separated from the planar drawing 410 as a shell cutting, and may be cut and processed according to a design.

In addition, injection molding is performed by injecting the inner case material into the inner case mold to which the formed outer case is coupled (S350).

That is, the inner case mold for forming the inner case is coupled to the formed outer case, and the inner case material, for example, expanded styrene (EPS), is injection molded while fixing the inner case mold to the outer case while the inner case mold is coupled to the outer case. An inner case may be formed.

At this time, strong pressure may be exerted on the outer case during injection molding of expanded styrene, and if the electric wire is placed in the existing outer case, the position of the electric wire is changed or exposed outside the outer case by this pressure, and the electric wire itself may be abnormal. There is a problem that the defect rate increases.

However, according to the smart helmet manufacturing method according to an embodiment of the present invention, since the electrical wiring is printed in the formed outer case, no matter how strong pressure is applied during injection molding, the position of the printed electrical wiring is changed or exposed outside the outer case There is no problem, and there is no case where an abnormality occurs in the printed electrical wiring itself.

Accordingly, it is possible to reduce the process of unnecessarily fixing the electric wire to the outer case, thereby increasing the simplification and efficiency of the process.

On the other hand, in printing the electrical wiring, when the outer case is formed by performing heat treatment on the plan view 410, a region that is shrunk, relaxed, or bent may occur, and the electrical wiring is printed in the region where it is contracted, relaxed, or bent. In this case, the effect of these deformations should be considered.

Accordingly, in the step of printing the electrical wiring ( S320 ), the number of printing of the electrical wiring may be changed with respect to an area in which the plan view is contracted, relaxed, or bent when the outer case is formed from the plan view.

Specifically, the step of printing the electrical wiring (S320) is the printing of the electrical wiring in consideration of the degree of contraction of the area where the plan view is contracted, the degree of relaxation of the relaxed area, and the degree of curvature of the bent area when the outer case is formed from the plan view. You can change the number of times.

For example, in the step of printing the electrical wiring ( S320 ), the number of printing of the electrical wiring may be decreased as the degree of contraction of the contracted region increases, and the number of printing of the electrical wiring may be increased as the degree of relaxation of the relaxed region increases. In addition, in the step of printing the electrical wiring ( S320 ), as the curvature of the bent region increases, the number of printing of the electrical wiring may be reduced.

That is, in the step of printing the electrical wiring ( S320 ), as the degree of contraction of the contracted region increases, the electrical wiring printed on the contracted region may become thicker as the length becomes shorter and thicker. As the number of times is decreased and the degree of relaxation of the relaxed area increases, the electrical wiring printed on the relaxed area may become thinner or break as the length increases. As a result, even if the length of the electric wiring is increased, it is possible to prevent it from becoming thinner or broken.

Similarly, in the step of printing the electrical wiring (S320), the greater the curvature of the bent area, the shorter the length of the electrical wiring printed on the bent area or the possibility of agglomeration. Considering this, the number of printing of the electrical wiring By printing the electrical wiring thinly by lowering the value, the influence of the thickened electrical wiring can be minimized even if the length of the electrical wiring is shortened or bundled.

6 is a view for explaining a printing method according to an embodiment of the present invention.

Referring to FIG. 6 , electrical wirings 510 , 520 , 530 , and 540 are printed on a plan view 410 in consideration of positions of various electronic components.

Here, when the outer case is formed through a later heat treatment, the electrical wiring 530 printed on the bent area 610 on the current plan view 410 is greater than the curvature printed on the plan view 410 on the outer case formed later. It may appear as the electrical wiring 530' bent with a large curvature.

In this way, when the electric wiring is printed on the bent region 610 when the outer case is formed through subsequent heat treatment, the length of the electric wiring may be shortened or agglomerated as described above, so that the number of printing of the electric wiring is lowered to print. do.

In addition, when the outer case is formed through later heat treatment, the electrical wiring 540 printed on the region 620 that is relaxed on the current plan view 410 is the electric wiring printed on the plan view 410 on the outer case formed later ( By being relaxed than the 540 , the length may be increased or may appear as the electric wiring 540 ′ having a curved shape.

As described above, when the electrical wiring is printed on the region 620 that is relaxed when the outer case is formed through subsequent heat treatment, as described above, the electrical wiring may be thinned or broken as the length of the electrical wiring is increased. is increased to print.

As described above, the printing of the electrical wiring ( S320 ) may be performed by adjusting the number of printing in consideration of the influence of the printed electrical wiring when the plan view is deformed such as being contracted, relaxed, or bent.

Meanwhile, in the step of printing the electrical wiring ( S320 ), the thickness of the electrical wiring may be adjusted with respect to a region in which the plan view is contracted, relaxed, or bent.

That is, the electrical wiring printed on the region 720 to be bent through subsequent heat treatment increases the length of the electrical wiring through bending as shown in FIG. 7 (720 ′), and thus the length of the electrical wiring increases In order to keep the thickness of the electrical wiring uniform, when printing the plurality of electrical wirings 710 on a plan view from the beginning, the thickness is printed to be relatively thick as shown in FIG. 7 .

Similarly, in order to keep the thickness of the electrical wiring uniform even when the length of the electrical wiring is shortened through subsequent heat treatment and agglomerated, the thickness of the electrical wiring may be thinly printed when printing a plurality of electrical wirings on a plan view from the beginning. can

A plurality of printed electrical wirings spaced apart from each other or bent may be connected to each other.

Specifically, in the step of printing the electrical wiring (S320), one electrical wiring is cut and printed to be spaced apart from each other at a predetermined interval on the plan view, so that when the outer case is formed through a later heat treatment, it is cut in an area that is shrunk, relaxed, or bent. It is possible to enable electrical wirings to be connected as one electrical wiring.

That is, the electrical wiring printed on the region 820 to be bent through subsequent heat treatment is bent as shown in FIG. In order to keep the thickness of the electrical wiring uniform even if the wiring is agglomerated or the interval is shortened, a plurality of electrical wirings 810 are spaced apart at a predetermined interval as shown in FIG. 8 when printing on a plan view from the beginning Can be printed.

As described above, in the step (S320) of printing the electrical wiring, in consideration of the effect on the printed electrical wiring when the plan view is deformed such as shrinking, relaxing or bending, the interval at which the electrical wiring is disconnected It can be adjusted and printed.
