Technical Field

[0001] The present disclosure relates to a mobile two-way disinfection device, and more particularly, to a vehicle equipped with a mobile two-way disinfection device for simultaneously emitting visible light with a wavelength of 405 nm in the up and down directions of the mobile device. Background Art

[0002] In recent years, there has been an increasing trend to integrate mobile disinfection devices that combine charging and disinfection functions into vehicles.

[0003] This development stems from the growing concern about hygiene issues associated with various bacteria, including E. coli, Pseudomonas aeruginosa and Staphylococcus aureus, as people frequently use their hands to operate mobile devices, such as smartphones and mobile phones.

[0004] The mobile disinfection device is designed to solve the hygiene problem and is strategically placed within the center dashboard of the vehicle, specifically in front of the console armrest. The device includes an ultraviolet C (UVC) light emitting diode (LED) unit equipped for disinfection, a mobile base designed for mobile devices such as smartphones and mobile phones, and a reflector made of aluminum material.

[0005] The UVC LED unit emits UVC light to mobile devices (eg, smart phones and mobile phones) placed on the mobile base, and the reflector improves disinfection efficiency by concentrating and reflecting the emitted UVC light.

[0006] However, it is worth noting that UVC light with a wavelength range of 100nm to 280nm used for disinfection can pose potential health hazards and exhibit directional limitations depending on where the LED is installed. It also encounters difficulties in light transmission and diffusion.

[0007] Furthermore, since the UVC LED unit emits UVC light from top to bottom, the mobile disinfection device faces the challenge of disinfecting both the front and rear surfaces of mobile devices such as smartphones and mobile phones at the same time. Summary of the invention

[0010] In some examples, the visible light may have a wavelength of 405 nm generated by a light emitting diode (LED) mounted on a printed circuit board (PCB) substrate.

[0011] In some examples, downward, upward, and lateral emissions can be generated in a light guide plate made of a light guide film that is configured to diffuse visible light while forming a travel path for the visible light.

[0012] In some embodiments, the light guide plate may diffuse visible light using a light emitting surface coated with optical ink, and include a reflector configured to reflect the visible light to a surface opposite the light emitting surface.

[0013] In some embodiments, the light guide plate may form the light guide plate extension portion as a bent connection portion.

[0014] The present disclosure also relates to a vehicle equipped with a mobile two-way disinfection device, comprising: a center dashboard; a center dashboard charger that charges a mobile device and in which visible light of a second light emitting diode (LED) is diffused at a second light guide plate made of a light guide film and emitted toward a rear surface of the mobile device; and a console bracket located above the center dashboard charger, in which visible light of a first LED is diffused at a first light guide plate made of a light guide film and emitted toward a front surface of the mobile device.

[0015] In some embodiments, the center dashboard charger may be built-in and disposed at the center dashboard, and include a charging unit configured to charge the mobile device and a heat dissipation fan configured to cool heat generated by the charging unit.

[0022] Reference Figure 1 The mobile two-way disinfection device 1 uses the vehicle power supply (i.e., battery) in the center dashboard 200 of the vehicle 100 to perform the charging function of the mobile device 300, and at the same time, removes germs transmitted by human hands by disinfecting with visible light of 405nm wavelength, thereby enhancing the sanitation function. In this case, the center dashboard 200 is the location where the shift lever is installed and is connected to the console box (i.e., armrest) on the driver's seat side of the vehicle.

[0023] To this end, the mobile two-way disinfection device 1 is divided into a detachable mobile disinfection device 10-1 and a fixed mobile two-way disinfection device 10-2, the detachable mobile two-way disinfection device 10-1 is a type that is separated from the vehicle 100 and can be carried and moved by the user, and the fixed mobile two-way disinfection device 10-2 is integrated with the vehicle 100 and is attached to the center dashboard 200 of the vehicle 100 in a built-in manner so as not to be carried and moved by the user. In this case, the center dashboard 200 is only an example, and the mobile two-way disinfection device 1 can be installed using a squeeze pad or a console.

[0024] Specifically, the detachable mobile bidirectional disinfection device 10-1 includes a power charger 11, a movable cover (or hinged cover) 13, a disinfection light generator 20 and a light guide plate extension 50, and uses the power charger 11 to achieve a charging function, and uses the disinfection light generator 20 and the light guide plate extension 50 to achieve a disinfection function.

[0025] In addition, in the detachable mobile two-way disinfection device 10 - 1 , an external light indicator indicating that the mobile device 300 is charged and disinfected can be equipped with the power charger 11 or the movable cover 13 .

[0026] As an example, the power charger 11 is formed of a charging body of a built-in charging unit 11a and a heat dissipation fan 11b, the charging unit 11a is electrically connected to a jack or cable inserted into a power port installed in the vehicle 100, and charges the mobile device 300 and generates visible light from the disinfection light generator 20 using the supplied power, and the heat dissipation fan 11b cools the power charger 11 to resist the heat generated due to power supply at the lower part of the charging unit 11a.

[0027] Specifically, the charging unit 11 a may be powered by plugging a jack or a cable into a power port of a center dashboard charger 15 installed in the center dashboard 200 .

[0028] In addition, in the power charger 11 , a wireless charging pad capable of charging the mobile device 300 without inserting a cable or a plug may be applied to the charging unit 11 a .

[0029] As an example, the movable cover 13 is connected to one end of the charging body by the hinge pin 14 to form an integral structure with the charging body of the power charger 11, and in the closed state of the cover, the inner space of the cover surrounding the mobile device 300 is formed similarly to the upper surface of the charging body of the power charger 11. A quadrilateral enclosed space.

[0030] As an example, the disinfecting light generator 20 includes a first disinfecting light generator 20-1 and a second disinfecting light generator 20-2, the first disinfecting light generator 20-1 is placed and fixed on the cover inner wall 13a protruding into the movable cover 13, and the second disinfecting light generator 20-2 is connected and fixed to the support protrusion 11c protruding from one side of the charging body of the power charger 11.

[0031] As an example, by using the integrated structure of the first disinfection light generator 20-1 and the second disinfection light generator 20-2, the light guide plate extension 50 is formed as a curved connection portion in which the light guide plates 41 of the first disinfection light generator 20-1 and the second disinfection light generator 20-2 are connected (see Figure 2 and Figure 3 ).

[0032] Therefore, in the detachable mobile bidirectional disinfection device 10-1, when the power charger 11 and the movable cover 13 are closed, the first disinfection light generator 20-1 emits downward visible light from the movable cover 13 toward the power charger 11, and the second disinfection light generator 20-2 emits upward visible light from the power charger 11 toward the movable cover 13. In addition, the light guide plate extension 50 emits visible light generated by the first disinfection light generator 20-1 and the second disinfection light generator 20-2 laterally from one side of the movable cover 13 to the internal space of the cover.

[0033] Specifically, the fixed mobile bidirectional disinfection device 10 - 2 includes a center dashboard charger 15 , a console bracket 17 and a disinfection light generator 20 , and the center dashboard charger 15 is used to implement a charging function and the disinfection light generator 20 is used to implement a disinfection function.

[0034] In addition, in the fixed type mobile two-way disinfection device 10 - 2 , an exterior light indicator indicating completion of charging and disinfection of the mobile device 300 is applied to the center dashboard charger 15 or the console bracket 17 .

[0035] As an example, the center dashboard charger 15 is formed of a charging body having a built-in charging unit 15a that charges the mobile device 300 and generates visible light by the disinfection light generator 20 using power supplied through a center dashboard 200 provided in the vehicle 100, and the cooling fan 15b that cools the center dashboard charger 15 to resist heat generated by power supplied from a lower portion of the charging unit 15a.

[0036] In particular, the center dashboard charger 15 may be provided with a power port into which a jack or cable is plugged to supply power to the charging unit 11 a .

[0037] In addition, in the center dashboard charger 15 , a wireless charging pad capable of charging the mobile device 300 without inserting a cable or a plug may be equipped with a charging unit 15 a .

[0038] As an example, the console bracket 17 is formed in the console portion on the upper side of the center dashboard 200 to be separated from the center dashboard charger 15 and form a partition space with the center dashboard charger 15 so that the mobile device 300 can be placed on the upper surface of the center dashboard charger 15 .

[0039] As an example, the disinfecting light generator 20 includes a first disinfecting light generator 20-1 and a second disinfecting light generator 20-2, the first disinfecting light generator 20-1 is placed and fixed on a bracket protrusion 17a protruding into the console bracket 17, and the second disinfecting light generator 20-2 is connected and fixed to a support protrusion 15c protruding from one side of the charging body of the center dashboard charger 15.

[0040] Therefore, in the fixed mobile bidirectional disinfection device 10-2, when the center dashboard charger 15 and the console bracket 17 are separated, the first disinfection light generator 20-1 emits visible light downward from the console bracket 17 toward the center dashboard charger 15, and the second disinfection light generator 20-2 emits visible light upward from the center dashboard charger 15 toward the console bracket 17.

[0041] Reference Figure 2 , each of the first sterilizing light generator 20 - 1 and the second sterilizing light generator 20 - 2 includes the visible light LED unit 30 and the light diffusion unit 40 as the same components.

[0042] In the following, when the visible light-LED unit 30 is applied to the first disinfecting light generator 20-1, the first printed circuit board (PCB) substrate 31, the first LED 32 and the first light guide plate joint 33 are described, and when the visible light-LED unit 30 is applied to the second disinfecting light generator 20-2, although the second PCB substrate 31, the second LED 32 and the second light guide plate joint 33 are described, the PCB substrate 31, the LED 32 and the light guide plate joint 33 will not be distinguished.

[0043] Specifically, the visible light-LED unit 30 includes a PCB substrate 31, an LED 32, and a light guide plate coupling portion 33. In this case, the PCB substrate 31 is a typical component in which various electronic device components including semiconductors are integrated to generate visible light.

[0044] As an example, the PCB substrate 31 is electrically connected to supply power from the power charger 11 and the center dashboard charger 15, and generates visible light by controlling the current relative to the LED 32. The LED 32 is electrically connected to the PCB substrate 31 to generate visible light having a wavelength of 405 nm. The light guide plate joint portion 33 is connected to the light guide plate 41 of the light diffusion unit 40, and for this purpose, the light guide plate 41 is attached to the LED housing in a state of facing the front surface of the LED 32 using the LED housing.

[0045] In particular, see Figure 2From the transmittance of each wavelength, it can be seen that visible light with a wavelength of 405nm is transmittance, thus solving the problem of light directionality and transmittance caused by insufficient transmittance of existing UVC light with a wavelength range of 100nm-280nm.

[0046] Specifically, the light diffusion unit 40 includes a light guide plate 41 , optical ink 42 , and a reflector 43 .

[0047] As an example, since the light guide plate 41 is made of a light guide film and has a predetermined width and a predetermined length, the light guide plate 41 connects the visible light from one end facing the LED 32 to the other end of the traveling path and forms a light emitting surface that diffuses the visible light to the outside while passing through the traveling path. In this case, the light guide film is manufactured by a roll stamping process using an extruded raw sheet.

[0048] In addition, an optical ink 42 is applied or coated on a light emitting surface formed on one surface of the light guide plate 41 to increase the light diffusion effect of visible light, and a reflector 43 is stacked or attached to the other surface of the light guide plate 41 (i.e., a surface not coated with the optical ink 42) so that visible light is completely directed only toward the light emitting surface. In this case, the reflector 43 may be made of aluminum material.

[0049] Reference Figure 3 , the light guide plate extension 50 is a curved connection portion, and forms an integrated structure in which the first disinfection light generator 20-1 and the second disinfection light generator 20-2 are connected to each other in a "U" shape. Therefore, the number of light diffusion units 40 can be reduced from two units applied to the first disinfection light generator 20-1 and the second disinfection light generator 20-2 to one unit.

[0050] However, when there is one light diffusion unit 40 , the length of the light diffusion unit 40 is longer than the length of the bent connection portion compared to the case of two light diffusion units.

[0051] Therefore, the light guide plate extension 50 includes the light guide plate 41 , the optical ink 42 , and the reflector 43 , which are the same components as the light diffusion unit 40 .

[0052] on the other hand, Figure 4 and Figure 5 The mobile bidirectional disinfection device 1 is shown in use.

[0053] Reference Figure 4 The detachable mobile two-way disinfection device 10-1 is placed on the center dashboard 200, the cable or jack is inserted into the connector of the power charger 11 to supply power to the vehicle, and the movable cover 13 is moved upward by the hinge pin 14 to expose the upper surface of the power charger 11.

[0054] Then, when the mobile device 300 is placed on the light guide plate 41 of the second disinfecting light generator 20-2 exposed to the upper surface of the power charger 11, and then the movable cover 13 is moved downward to form an airtight space inside the cover, the battery charging of the mobile device 300 is performed by the charging unit 11a of the power charger 11. In this case, the heat dissipation fan 11b is driven to cool the heat generated due to the charging process.

[0055] At the same time, the airtight space between the power charger 11 and the movable cover 13 is filled with downward visible light, upward visible light and lateral visible light. The downward visible light is emitted from the LED 32 of the first disinfecting light generator 20-1 set in the movable cover 13 and is emitted downward into the internal space of the cover due to light diffusion of the light guide plate 41 of the light diffusion unit 40. The upward visible light is emitted from the LED 32 of the second disinfecting light generator 20-2 set in the power charger 11 and is emitted upward into the internal space of the cover due to light diffusion of the light guide plate 41 of the light diffusion unit 40. The lateral visible light is emitted toward the inside of the internal space of the cover due to light diffusion of the light guide plate 41 of the light guide plate extension 50 located on one side of the movable cover 13.

[0056] Then, since all surfaces of the mobile device 300 are disinfected by the downward visible light, upward visible light and lateral visible light in the internal space of the cover, the upward, downward and lateral light diffused by the two light sources and the light guide film significantly enhances the disinfection effect, thereby enhancing the hygiene function through sterilization.

[0057] Then, when the external light indicator confirms that the charging and sterilization of the mobile device 300 is completed, the movable cover 13 moves upward again to open the cover inner space, unload the charged and sterilized mobile device 300, and then the movable cover 13 moves downward again.

[0058] Reference Figure 5 When the mobile device 300 is placed on the center dashboard charger 15 of the center dashboard 200, the battery is charged by the charging unit 15a of the center dashboard charger 15. In this case, the cooling fan 15b is driven to cool the heat generated by the charging process.

[0059] At the same time, the separation space is filled with downward visible light emitted from the LED 32 of the first disinfection light generator 20-1 set in the console bracket 17 that forms the separation space with the center dashboard charger 15 and emitted downward to the separation space due to light diffusion of the light guide plate 41 of the light diffusion unit 40, and upward visible light emitted from the LED 32 of the second disinfection light generator 20-2 set in the center dashboard charger 15 and emitted upward to the separation space due to light diffusion of the light guide plate 41 of the light diffusion unit 40.

[0060] Then, since the mobile device 300 is fully disinfected by separating the downward visible light and the upward visible light in the space, the disinfection effect is enhanced by the upward and downward light diffusion of the two light sources and the light guide film, so that the sanitation function can be enhanced through sterilization.

[0061] Thereafter, when completion of charging and disinfection of the mobile device 300 is confirmed by the exterior light indicator, the mobile device 300 is unloaded from the center dashboard charger 15 .

[0062] As described above, the mobile two-way disinfection device 1 used in the vehicle 100 may include: a detachable mobile two-way disinfection device 10-1, in which a light guide plate 41 made of a light guide film is connected from the power charger 11 to the movable cover 13 by bending the light guide plate extension 50 to emit visible light from the LED 32 to the front surface, rear surface and side surface of the mobile device 300; or a fixed mobile two-way disinfection device 10-2, in which the light guide plate 41 made of a light guide film emits the visible light of the LED 32 to the rear surface and front surface of the mobile device 300 located at the console bracket 17 and the center dashboard charger 15, solving the harm to the human body of the omnidirectional disinfection effect of the visible light of 405nm wavelength on the mobile device 300 as well as the problems of directionality and light transmittance, and in particular, since the light guide plate extension 50 amplifies the energy of the visible light, the disinfection effect of the amount of light is maximized and the production cost is reduced.

[0063] According to the mobile two-way disinfection device applied to a vehicle disclosed in the present invention, since the visible light with a wavelength of 405nm is used for disinfection, the problem of harm to the human body and the problems of the directionality and transmittance of light can be solved.

[0064] In addition, according to the mobile bidirectional disinfection device, the disinfection effect is enhanced by diffusing light in the upward, downward and lateral directions from the light-guiding film of the two light sources that emit visible light in two directions along the mobile device, which can enhance the hygiene function and expand the market by removing bacteria transmitted through human hands.

[0065] In addition, according to the mobile bidirectional disinfection device, the curved connection structure of the light-guiding film is adopted to integrate the two light sources, and the energy of the upper and lower light sources is amplified by the curved surface, which can maximize the disinfection effect of the amount of light passing through and reduce production costs.
