Description

Technical Field

[0001] The utility model relates to the technical field of luminous shoe design, in particular to a shoe structure with a cold light sheet. Background Art

[0002] With the development of society and the improvement of people's living standards, when consumers choose shoes, they not only require the shoes to have the function of protecting the wearer's feet, but also require different appearances or styles. At present, for the luminous shoes on the market, the luminous light sources are mostly LED lights or small lamp beads. Both LED lights and small lamp beads emit light at single points, with poor luminous effects. Moreover, the energy consumption of LED lights and small lamp balls is relatively large, resulting in a short service life of the battery, and thus a short luminous use time of the shoes. The cold light sheet, abbreviated as EL (Electro Luminescent electro-luminescence), is a physical phenomenon in which a fluorescent substance emits light under the excitation of an electric field generated by an alternating voltage applied to the two end electrodes, that is, an electric field luminescence phenomenon. By combining various substances to produce light sources of different colors, it has the characteristics of low power consumption, soft light, no ultraviolet rays, diverse colors, long life, and no heat generation. Therefore, it is generally called a cold light source. Different from the traditional point or line light-emitting mechanism, the cold light source is a uniform and integral surface light-emitting body, and it is also a light source that will not cause glare to the vision, has no harm, is elastic, and can be cut into any complex shape.

[0003] In the prior art, the patent with the publication number of CN110934383A discloses a new type of artificial cold light shoe, including a shoe sole, a shoe upper and a shoe barrel. The shoe upper is fixed on the shoe sole; the shoe barrel is arranged at the rear end of the shoe upper, and a drawstring is arranged at the upper end of the shoe barrel. A plurality of cold light sheets are arranged outside the shoe barrel. Among them, the cold light sheet is connected to the outside of the shoe barrel through a detachable component. The detachable component includes a mounting part, an inlay block and a clamping part. The mounting part is fixedly connected to the inner side wall of the cold light sheet; the inlay block is snap-fitted into the side groove of the shoe barrel; the clamping part is installed on the outside of the inlay block through a screw. Since a detachable component is arranged on one side of the cold light sheet, through the connection and cooperation of the mounting part, the inlay block and the clamping part, it is relatively convenient to replace the cold light sheet.

[0004] The patent with the publication number CN203058549U discloses a light-emitting shoe, which includes a shoe body and a light-emitting device. The shoe body has a sole and an upper surface provided on the upper surface of the sole. The light-emitting device includes a cold light sheet and a control box. One side of the cold light sheet is attached to the outer surface of the upper surface, and a pattern layer is coated on the other side of the cold light sheet. The control box is installed inside the upper surface of the sole. The control box is provided with a power supply battery, a control switch, and a control module. The power supply battery, the control switch, and the control module are electrically connected to the cold light sheet in sequence, and the control switch extends outside the control box and extends to the lower bottom surface of the sole. Compared with the prior art, the cold light sheet is used as the light-emitting source. The cold light sheet consumes less energy than LED lights and small lamp beads, greatly reducing the power consumption of the light-emitting device and extending the service life of the light-emitting device. At the same time, the cold light sheet emits light in a whole-piece manner, and the light emission is relatively uniform, greatly improving the light-emitting effect. The pattern layer on the cold light sheet can be used to decorate the shoes, enhancing the overall beauty of the shoes.

[0005] In the above technical solution, although the cold light sheet is used as a light source and applied to the shoes, its forming process and pattern design of the cold light sheet are relatively complex and not suitable for mass production.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the protection scope of the present utility model.

[0028] Embodiment 1

[0029] Refer to Figures 1-4As shown in the figure, a shoe structure with a cold light sheet according to the present utility model includes a sole 20 and a shoe body 21. Generally, the shoe body 21 and the sole 20 are separately manufactured first and then fixedly connected to form a shoe. The shoe body 21 is provided with a common upper material of mesh or leather to meet the requirement that a light-emitting sheet 1 is hot-melt bonded to the shoe body 21. The light-emitting sheet 1 is electrically connected to a battery 3 through a wire 6. The battery 3 is embedded in a slot in the sole 20 and is connected to a control unit 4 through a wire 6. A control panel is built into the control unit 4, and a switch and a USB charging interface are externally connected and placed at the rear of the shoe body 21. The wire 6 connecting the battery 3 and the control unit 4 extends along the slot of the sole 20 to the rear of the shoe body 21; the light-emitting sheet 1 is formed by sequentially laminating a protective layer 10, a base layer 11, a pattern layer 12, a conductive layer 13, a light-emitting layer 14, a back electrode layer 15, and a connection layer 16. The protective layer 10 is laminated on the base layer 11 and a pattern is printed on the base layer 11. The conductive layer 13 and the back electrode layer 15 are electrodes, the light-emitting layer 14 is a fluorescent powder body, and the connection layer 16 is connected to the electrodes through flexible flat cables and is provided with connection ports.

[0030] Embodiment 2

[0031] Referring to Figures 1-4 As shown in the figure, on the basis of the technical solution of Embodiment 1, a shoe structure with a cold light sheet is as Figures 3-4 shown in the figure. A adapter 5 is provided on the wire 6 between the light-emitting sheet 1 and the battery 3. The adapter 5 is an element that converts direct current to alternating current, that is, it can convert the direct current of the battery 3 into the alternating current required when the light-emitting sheet 1 works. The joint parts at both ends of the adapter 5 are coated with a waterproof layer to enhance its waterproof function.

[0032] Furthermore, the switch is a waterproof push-button. A waterproof plug is inserted at the USB charging interface. This design is to improve the waterproof effect as much as possible and can also adapt to weather with high air humidity. Of course, in rainy days or when washing with water, it is generally not recommended to use or operate to avoid water seepage affecting the electronic components of the circuit and causing a short circuit and damage. In addition, a lifting ring is provided at the rear of the shoe body 21, and the control unit 4 is located inside the lifting ring. The design of the lifting ring plays a role in hiding the control unit 4 and has a certain decorative and aesthetic effect.

[0033] Embodiment 3

[0034] Referring to Figures 1-4 As shown in the figure, on the basis of the technical solution of Embodiment 1, a shoe structure with a cold light sheet is as Figure 2As shown, the base layer 11 is a TPU film or a TPE film, and the protective layer 10 is a release film with one of PET, PE, OPP, BOPET, and BOPP as the base material. Since the material of the base layer 11 has poor tensile resistance and is prone to elongation under the screen printing pressure during the printing process, which will affect the printing and light-emitting effect, it is necessary to laminate a protective layer 10 to prevent elongation. After the production process is completed, the protective layer 10 can be peeled off. Specifically, the protective layer 10 is laminated on the base layer 11 by double hot pressing wheels, and then wound and stored, which can reduce the printing deformation of the base layer 11 and improve the anti-breakage ability. After winding, they will not stick together. During subsequent printing and processing, the release film is adhesively bonded to the printing table to prevent contamination of the surface of the base layer 11.

[0035] Furthermore, the pattern layer 12 is formed by printing TPU ink on a screen, the light-emitting layer 14 is formed by printing phosphor powder on a screen, the conductive layer 13 and the back electrode layer 15 are both electrodes made of conductive silver, and the connection layer 16 is a printed flexible cable. The flexible cable is attached to the edges of the conductive layer 13 and the back electrode layer 15 and is provided with connection ports. In addition, the shoe upper material at the bonding part between the shoe body 21 and the light-emitting sheet 1 is a mesh cloth or a leather surface, and the light-emitting sheet 1 is adhesively fixed to the mesh cloth or the leather surface by hot pressing with a hot melt adhesive film, generally using a 0.1 - 0.35 mm hot melt adhesive film.

[0036] As Figures 1-2 shown, first design the shape and size of the light-emitting pattern required. The light-emitting sheet 1 must have positive and negative electrodes. Normal electrodes use copper or silver powder. The electrodes are only responsible for conducting electricity and not for emitting light. The light-emitting body is a fluorescent powder, and its color is different from that of the electrodes. When the two are printed together, two colors will appear. To ensure that all the patterns seen are light-emitting bodies, the electrodes need to be covered, and printing is carried out in two steps. To ensure clear edges, a 100 - 250 mesh screen is used to develop the printing screen for the light-emitting pattern. According to the size of the light-emitting pattern, 3 mm is added to the periphery of the pattern edge to print the electrodes of the conductive layer 13, and the printed pattern outer frame is obtained. An 80 - 200 mesh screen is used to develop the printing plate. According to the size of the light-emitting pattern, 2.2 - 2.5 mm is added to the periphery of the pattern edge to print the light-emitting layer 14, and the printing screen for the light-emitting layer 14 is obtained. A 100 - 200 mesh screen is used to develop the printing plate. According to the size of the light-emitting pattern, 3 mm is added to the periphery of the pattern edge to print the electrodes of the back electrode layer 15, and the printed pattern outer frame is obtained. A 100 - 200 mesh screen is used to develop the printing plate.

[0037] Modify the knife. According to the layout drawing, reduce the perimeter by 1 mm to obtain the fixture size. Open a high-frequency fusing mold, and mark alignment points on the mold. Using the opened high-frequency fusing mold, with the printed alignment line as the reference, fuse the printed light-emitting sheet 1 to the correct size. Or according to the layout drawing, reduce the perimeter by 1 mm to obtain the fixture size. Open a crystal knife mold. Using the opened crystal knife mold, with the printed alignment line as the reference, blank the printed light-emitting sheet 1 to the correct size.

[0038] Flat iron the shoe upper. According to the shoe upper lines, open a shoe upper flat iron mold. Sequentially place the light-emitting sheet 1, hot melt adhesive film, and shoe upper material. Place them on the platform machine for hot pressing. The machine temperature is 180 - 200 °C, the pressure is 15 - 30 KG, and the time is 15 - 24 seconds. Place them on the platform machine for cooling. The machine temperature is -10 - 15 °C, the pressure is 10 - 20 KG, and the time is 10 seconds. Take out the protective layer 10.
