[0029] The technical solutions in the implementations of this application will be clearly and completely described below with reference to the accompanying drawings. It is clear that the implementations described are merely a part of, and not all of, the implementations of this application. All other implementations that can be obtained by those skilled in the art based on the implementations of this application without creative effort are within the scope of protection of this application.

[0030] Note that when one assembly is said to be "fastened" to another, that assembly may be directly on top of the other, or there may be an assembly between them. When one assembly is said to be "connected" to another, that assembly may be directly connected to the other, or there may be an assembly between them.

[0031] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as those commonly understood by those skilled in the art relating to this application. Terms used herein are intended solely to describe specific embodiments and are not intended to limit this application. The term "and / or" as used herein includes any combination of one or more related enumerated items.

[0032] In the following, several implementations of this application will be described in further detail with reference to the attached drawings. Where there is no conflict, the following embodiments and features in the embodiments may be combined with each other.

[0033] For related technical information, see Figure 1. The transparent window 2' and the lampshade body 1' of the lampshade 10' are arranged in parallel. When a user views the lampshade 10', they can directly see the component construction on the opposite side of the lampshade 10' through the transparent window 2', which affects the aesthetic appearance of the in-car refrigerator.

[0034] Refer to Figures 2 and 3. To solve the aforementioned problems, this application provides a lampshade 100. The lampshade 100 includes a lampshade body 101. The lampshade body 101 has a first side surface 1011 and a second side surface 1012 that are opposite to each other. The lampshade 100 includes a recessed structure 102 that is recessed toward the first side surface 1011. The recessed structure 102 includes a transparent portion 1021. The transparent portion 1021 is capable of transmitting light from a germicidal lamp 400 disposed on the first side surface 1011 outward from the second side surface 1012.

[0035] In the technical solution of this application, the lampshade body 101 of the lampshade 100 has a first side surface 1011 facing the germicidal lamp 400 and a second side surface 1012 facing outward. The lampshade 100 is provided with a recessed structure 102 that is recessed toward the first side surface 1011, so that a visual blind spot area may be formed on the second side surface 1012 of the lampshade body 101, and a transparent portion 1021 is disposed in the blind spot area. Light from the germicidal lamp 400 can be transmitted to the outside of the lampshade 100 through the transparent portion 1021. From a normal viewpoint, the user cannot clearly see the component structure disposed on the first side surface 1011 of the lampshade body 101 through the transparent portion 1021. This enhances the aesthetic appearance of the vehicle, the in-car refrigerator 10000 (see Figure 10), or the lamp assembly 1000 (see Figure 6), including the lampshade 100, and improves the user experience.

[0036] The lampshade 100 includes a lampshade body 101. The lampshade body 101 is configured to block the user's line of sight, preventing the user from seeing the component structure on the opposite side of the lampshade body 101 through the lampshade body 101, thereby enhancing the overall aesthetic appearance of the object on which the lampshade 100 is provided.

[0037] The lampshade body 101 is provided with a recessed structure 102 to create a visual blind spot, and the transparent portion 1021 is disposed within the recessed structure 102. The recessed structure 102 further includes a support portion 1022. One end of the support portion 1022 is connected to the lampshade body 101, and the other end is connected to the transparent portion 1021. The support portion 1022 is configured to support the transparent portion 1021 and is configured to improve the connection strength between the transparent portion 1021 and the lampshade body 101.

[0038] The support portion 1022 may be connected to any position on the transparent portion 1021 in order to provide support for the transparent portion 1021. In a possible implementation of this application, one end of the transparent portion 1021 is connected to the lampshade body 101 and the other end is connected to the support portion 1022. The support portion 1022 is connected to the furthest end of the transparent portion 1021 (the end of the transparent portion 1021 away from the lampshade body 101) in order to minimize obstruction of the transparent portion 1021 by the support portion 1022 and to increase the light transmission area of ​​the transparent portion 1021.

[0039] The lampshade body 101, the transparent portion 1021, and the support portion 1022 may be made from a variety of materials. For example, in a possible implementation of this application, the lampshade body 101 is made from a light-transmitting but opaque material so as to allow light to pass through while blocking the user's line of sight. The light-transmitting but opaque material may be, and is not limited to, frosted glass, light-transmitting cloth, or dyed plastic formed by injection molding of dyes and plastics. The support portion 1022 may be made from a light-shielding material or a light-transmitting but opaque material so as to provide support for the transparent portion 1021 while preventing the user from clearly seeing the component structure disposed on the first side surface 1011 of the lampshade body 101 through the support portion 1022. The support portion 1022 may be made from metal or plastic, and is not limited to this application. The support portion 1022 is preferably made from metal. Compared to plastics, metals have higher hardness and a more stable molecular structure. Therefore, if the support portion 1022 is made of metal, the support portion 1022 can not only better support the transparent portion 1021, but can also avoid its own degradation and deterioration over time caused by long-term exposure to light from the germicidal lamp 400. The transparent portion 1021 is made of a colorless transparent material to facilitate the transmission of light from the germicidal lamp 400. The colorless transparent material may be quartz glass, transparent plastic, or transparent resin, and is not limited to this application. The light from the germicidal lamp 400 is mostly ultraviolet light. Taking this into consideration, in possible implementations of this application, the transparent portion 1021 is made of a cyclic block copolymer (CBC). Compared to other materials, the transparent portion 1021 made of a cyclic block copolymer has a higher ultraviolet transmittance.In addition, compared to other materials, cyclic block copolymers have a more stable molecular structure, so the transparent portion made from cyclic block copolymers can effectively reduce the rate of degradation of the transparent portion 1021 under light from the germicidal lamp 400, extend the service life of the lampshade 100, and guarantee the germicidal effect of the germicidal lamp 400.

[0040] The lampshade body 101, the transparent portion 1021, and the support portion 1022 may be made from the same material. Specifically, in another possible implementation of this application, the lampshade body 101, the transparent portion 1021, and the support portion 1022 are all made from a colorless, transparent material. The colorless, transparent material may be quartz glass, transparent plastic, transparent resin, or acrylic, and is not limited to this application. In a possible implementation of this application, the lampshade body 101, the transparent portion 1021, and the support portion 1022 are all made from a cyclic block copolymer (CBC) having a more stable molecular structure, thereby avoiding premature deterioration and changes over time of the lampshade body 101, the transparent portion 1021, and the support portion 1022 under light from the germicidal lamp 400. The surfaces of the lampshade body 101, the transparent portion 1021, and the support portion 1022 are further coated with a light-transmitting coating to block the user's line of sight and prevent the user from seeing structures on the opposite side of the lampshade 100 through the lampshade body 101 and support portion 1022. The light-transmitting coating may be made from ultraviolet (UV) resistant paint or matte transparent paint, and is not limited to this application. In possible implementations of this application, the lampshade body 101 and support portion 1022 are coated with ultraviolet (UV) resistant paint, thereby further reducing the adverse effects of light from the germicidal lamp 400 on the lampshade body 101 and support portion 1022 and improving the service life of the lampshade 100.

[0041] When the lampshade body 101, the transparent portion 1021, and the support portion 1022 are all made from the same material, the lampshade body 101, the transparent portion 1021, and the support portion 1022 may be integrally formed or separately arranged, and this is not limited to the present application. In possible implementations of the present application, the lampshade body 101, the transparent portion 1021, and the support portion 1022 are integrally formed, thereby reducing the manufacturing cost of the lampshade 100.

[0042] The recessed structure 102 may have various shapes. Refer to Figure 3. Figure 3 shows a first embodiment of the recessed structure 102. For ease of explanation, in this embodiment, the transparent portion 1021, the support portion 1022, and the lampshade body 101 are all considered to be plate structures having flat surfaces. The lampshade body 101 is constructed as a first plate. The transparent portion 1021 is constructed as a third plate. The support portion 1022 is constructed as a second plate. Based on this, in this embodiment, the extensions of the transparent portion 1021, the support portion 1022, and the lampshade body 101 jointly surround a triangular structure. A second narrow angle A is formed between the lampshade body 101, which is constructed as a first plate, and the transparent portion 1021, which is constructed as a third plate. If the second angle A is excessively small, it should be understood that the light emitted by the germicidal lamp 400 will not easily pass outward through the transparent portion 1021. If the second angle A is excessively large, the transparent portion 1021 may be visible to the user. Therefore, in possible implementations of this application, the second angle A satisfies 60° ≤ A ≤ 150°. When A = 90°, it can be ensured that the transparent portion 1021 is located within the user's visual blind spot, allowing light from the germicidal lamp 400 to pass through. In this way, when the user views the lampshade body 101 from point S, the user can see only the support portion 1022 connected to the lampshade body 101, but not the transparent portion 1021 located behind the lampshade body 101, thereby preventing the user from clearly seeing the component structure disposed on the first side surface 1011 of the lampshade body 101 through the transparent portion 1021.

[0043] In the possible implementation of this application, a first narrow angle B is formed between the first plate formed by the lampshade body 101 and the second plate formed by the support portion 1022. When 90° ≤ B ≤ 160°, the support portion 1022 can not only properly support the transparent portion 1021, but also ensure that light from the germicidal lamp 400 is properly transmitted outward from the transparent portion 1021.

[0044] Refer to Figure 4. Figure 4 shows a second embodiment of the recessed structure 102. In this embodiment, the support portion 1022 includes a first support plate 10221 and a second support plate 10222. One end of the first support plate 10221 is connected to the lampshade body 101, and the other end is connected to one end of the second support plate 10222. The other end of the second support plate 10222 is connected to the transparent portion 1021. The extensions of the transparent portion 1021, the support portion 1022, and the lampshade body 101 jointly enclose a rectangular structure. Similarly, in this embodiment, the second narrow angle A formed by the transparent portion 1021 and the lampshade body 101 satisfies 60° ≤ A ≤ 150°. In this way, when a user views the lampshade body 101 from point S, the user can only see the support portion 1022 connected to the lampshade body 101, and cannot see the transparent portion 1021 located behind the lampshade body 101.

[0045] Refer to Figure 5. Figure 5 shows a third embodiment of the recessed structure 102. In this embodiment, the support portion 1022 has an arc-shaped structure. The extensions of the transparent portion 1021, the support portion 1022, and the lampshade body 101 jointly surround the arc-shaped structure. In this embodiment, the second angle A formed by the transparent portion 1021 and the lampshade body 101 satisfies 60° ≤ A ≤ 150°. In this way, when viewing the lampshade body 101 from point S, the user also cannot see the transparent portion 1021 behind the lampshade body 101.

[0046] The lampshade 100 provided by this application may have various application scenarios. See, for example, Figure 6. In a possible implementation of this application, the lampshade 100 may be used in a lamp assembly 1000. The lamp assembly 1000 includes a base 200, a germicidal lamp 400, and the lampshade 100. The lampshade 100 is fixed to the base 200. The first side surface 1011 of the lampshade body 101 of the lampshade 100 is positioned corresponding to the base 200. The lampshade 100 and the base 200 jointly surround a cavity 300. The germicidal lamp 400 is positioned within the cavity 300. Light from the germicidal lamp 400 is transmitted outward through the transparent portion 1021 of the lampshade 100.

[0047] In this embodiment, the lampshade 100 is disposed on the base 200 of the lamp assembly 1000. The lampshade 100 and the base 200 jointly surround the cavity 300. The germicidal lamp 400 is disposed inside the cavity 300. Light from the germicidal lamp 400 is transmitted outward through the transparent portion 1021 of the lampshade 100. However, the presence of the recessed structure 102 prevents the user from seeing other internal structures of the lamp assembly 1000 through the transparent portion 1021 from a normal viewpoint, thereby improving the aesthetic appearance of the lamp assembly 1000.

[0048] The germicidal lamp 400 is configured to emit germicidal light outward to kill external bacteria. The germicidal lamp 400 may be, but is not limited to, a straight tube hot cathode low-pressure mercury ultraviolet lamp, an ozone ultraviolet lamp, or a UV ultraviolet lamp.

[0049] It should be understood that the lamp assembly 1000 may further include an illumination lamp 500. The illumination lamp 500 is configured to emit illumination light for everyday lighting. The illumination lamp may be an incandescent lamp or an LED lamp, and is not limited thereto in this application.

[0050] The base 200 is configured to form a space for mounting the germicidal lamp 400. The base 200 is provided with a mounting opening. The germicidal lamp 400 is mounted to the base 200 through the mounting opening. The base 200 may be made of metal or plastic, and is not limited to this application. The lampshade 100 covers the base 200. The lampshade 100 may be connected to the base 200 in a variety of ways. For example, the lampshade 100 may be connected to the base 200 by screws, or it may be connected to the base 200 in a magnetically attractive manner, and is not limited to this application. See Figure 7. In a possible implementation of this application, the lampshade 100 further includes a plurality of snap-fit ​​joints 103. The snap-fit ​​joints 103 are disposed on the first side surface 1011 of the lampshade body 101 and are fixed to the lampshade body 101. The base 200 includes a slot 201. The snap-fit ​​joint 103 of the lampshade 100 is snap-fitted into the slot 201 of the base 200 in order to fix the lampshade 100 to the base 200. Compared to other connection methods, using the snap-fit ​​joint 103 of the lampshade 100 can reduce the manufacturing cost of the lampshade 100 and improve assembly efficiency between the lampshade 100 and the base 200, thereby saving costs.

[0051] Refer to Figures 6 and 8. The lamp assembly 1000 further includes a circuit board 600. The circuit board 600 is connected to the base 200 via screws, magnetic attraction, or other fastening methods. The circuit board 600 is connected to a power supply. The illumination lamp 500 and the germicidal lamp 400 are electrically connected to the circuit board 600. By arranging the circuit board 600, the wiring of the illumination lamp 500 and the germicidal lamp 400 within the cavity 300 can be streamlined, reducing the amount of wiring harness used to electrically connect the illumination lamp 500 and the germicidal lamp 400, and thus reducing assembly costs. In addition, the circuit board 600 can provide support for the arrangement of the germicidal lamp 400. By changing the orientation of the circuit board 600 within the cavity 300, the irradiation direction of the germicidal lamp 400 can be changed.

[0052] It should be understood that if the angle between the germicidal lamp 400 and the transparent portion 1021 is excessively large, the ultraviolet light emitted by the germicidal lamp 400 may not reach the transparent portion 1021. If the angle is excessively small, the light transmitted outside the transparent portion 1021 may be directly refracted by the support portion 1022 and may not be transmitted outside the recessed structure 102. Therefore, in possible implementation modes of this application, an angle is formed between the lampshade body 101 and the circuit board 600. To facilitate the explanation of the beneficial effects of this embodiment, an example is used for explanation in which the outer contours of both the lampshade body 101 and the circuit board 600 are configured as plate-type structures having flat surfaces. In this structure, the lampshade body 101 is constructed as a first plate. A third angle C is formed between the circuit board 600 and the lampshade body 101. When 10° ≤ C ≤ 60°, the transparent portion 1021 exhibits the best refractive effect and maximum refractive range for ultraviolet light emitted by the germicidal lamp 400.

[0053] In a possible implementation of this application, a narrow angle D is formed between the lampshade body 101 and the support portion 1022 to prevent the light from the germicidal lamp 400 from reaching the support portion 1022 and causing deterioration of the support portion 1022. To facilitate the explanation of the beneficial effects of this embodiment, an example is used for explanation in which the outer contours of both the lampshade body 101 and the support portion 1022 are configured as plate-type structures having flat surfaces. In this structure, the lampshade body 101 is constructed as a first plate. The support portion 1022 is constructed as a second plate. A fourth narrow angle D is formed between the circuit board 600 and the support portion 1022. When 60°≦D≦120°, it can be ensured that the light from the germicidal lamp 400 is transmitted outward, while also ensuring that the light emitted by the germicidal lamp 400 does not reach the support portion 1022.

[0054] Refer to Figures 8 and 9. The lamp assembly 1000 further includes a light baffle 700. The light baffle 700 is fixed to the circuit board 600. The light baffle 700 is positioned between the germicidal lamp 400 and the lampshade body 101 to block the light from the germicidal lamp 400 to the lampshade body 101, thereby preventing the light from the germicidal lamp 400 from reaching the lampshade body 101 and reacting with the lampshade body 101 to cause deterioration and yellowing of the lampshade body 101.

[0055] In the possible implementations of this application, one end of the light baffle 700 is in contact with the transparent portion 1021. The statement that one end of the light baffle 700 is in contact with the transparent portion 1021 will be explained in detail as meaning that the light baffle 700 is completely fitted into the transparent portion 1021 without transmitting force to the transparent portion 1021, thereby preventing light from the germicidal lamp 400 from leaking outward from the contact point between the light baffle 700 and the transparent portion 1021 without damaging the transparent portion 1021, and thereby improving the blocking effect of the light baffle 700 against light from the germicidal lamp 400.

[0056] The light baffle 700 and the circuit board 600 may be fixed in various ways. The light baffle 700 may be directly screwed to the circuit board 600, or it may be fixed to the circuit board 600 by magnetic attraction, and this is not limited to this application. In a possible mounting configuration of this application, the light baffle 700 includes a hook portion 702 and a blocking portion 701 connected to the hook portion 702. The blocking portion 701 is configured to block light from the germicidal lamp 400 to the lampshade body 101. The hook portion 702 is configured to allow the light baffle 700 to be hooked onto the circuit board 600. Compared to other mounting configurations, the configuration of attaching the light baffle 700 to the circuit board 600 via the hook portion 702 is simpler and more efficient.

[0057] To block light, in possible implementations of this application, the blocking portion 701 includes a first blocking portion 7011 and at least two second blocking portions 7022. The first blocking portion 7011 and the second blocking portions 7022 may be integrally formed or separately arranged, and this is not limited to this application. To block light from the germicidal lamp 400 to the lampshade body 101, the first blocking portion 7011 and the second blocking portions 7022 jointly surround at least one barrier space, the germicidal lamp 400 is arranged within that barrier space.

[0058] Referring to Figures 10 and 11, the lampshade 100 provided by this application may be further used in a vehicle refrigerator 10000. In some possible implementations of this application, the lampshade 100 may be installed in the vehicle refrigerator 10000 via a lamp assembly 1000. Specifically, the vehicle refrigerator 10000 includes a refrigerator housing 11000 and a lamp assembly 1000. A refrigeration cavity 12000 is formed in the refrigerator housing 11000. A mounting hole 13000 is formed on the internal cavity surface of the refrigeration cavity 12000, penetrating the refrigerator housing 11000. The lampshade 100 of the lamp assembly 1000 covers the mounting hole 13000.

[0059] It should be understood that the vehicle refrigerator 10000 should further include a refrigeration system. The refrigeration system is configured to exchange heat in the refrigeration cavity 12000 in order to generate cold air within the refrigeration cavity 12000. The refrigeration system is a means of common art to those skilled in the art and is therefore not described in detail in this application.

[0060] In this embodiment, the refrigerated cavity 12000 of the vehicle refrigerator 10000 is configured to store food or other items that require refrigeration. The lamp assembly 1000 is configured to kill bacteria in the food or items stored in the refrigerated cavity 12000. The germicidal lamp 400 of the lamp assembly 1000 may emit light into the refrigerated cavity 12000 through the transparent portion 1021. The recessed structure 102 of the lampshade 100 prevents the user from clearly seeing the internal structure of the lamp assembly 1000 through the transparent portion 1021 from a normal viewpoint, thereby improving the overall aesthetic appearance of the vehicle refrigerator 10000.

[0061] In some other possible implementations of this application, the lampshade 100 may be directly mounted on the vehicle refrigerator 10000, which may allow light to pass through the vehicle refrigerator 10000 while preventing the user from seeing the internal structure of the vehicle refrigerator 10000, thereby improving the overall aesthetic appearance of the vehicle refrigerator 10000. It should be noted that the light in the vehicle refrigerator 10000 may be emitted by an ultraviolet lamp, an infrared lamp, or a lamp of another color, and this is not limited to this application.

[0062] The lampshade 100 provided by this application may be further used in a vehicle. Specifically, in some embodiments of this application, the application provides a vehicle. The vehicle includes an on-board refrigerator 10000, which includes a lampshade 100, or a lamp assembly 1000 having a lampshade 100.

[0063] In some embodiments of this application, the vehicle provided by this application may further include a lamp assembly 1000, which includes a lampshade 100. Light from the germicidal lamp 400 of the lamp assembly 1000 may be transmitted outward from the lampshade 100 into the interior of the vehicle for sterilization and disinfection. However, the presence of the recessed structure 102 of the lampshade 100 prevents the user from clearly seeing the internal construction of the lamp assembly 1000 from the outside, thereby improving the overall aesthetic appearance of the vehicle.

[0064] In some embodiments of this application, the lampshade 100 provided herein may be directly mounted on the vehicle, thereby allowing light to pass through the vehicle while preventing the user from seeing the vehicle's internal structure. The light in the vehicle may be emitted by ultraviolet lamps, infrared lamps, or other colored lamps, and this is not limited herein.

[0065] In the description of this application, orientations or positional relationships indicated by terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," and "circumferential" are orientations or positional relationships in the drawings and are intended solely to facilitate and simplify the description of the embodiments of this application, rather than indicating or implying that the devices or elements shown must have a particular orientation or must be constructed and operated in a particular orientation. Therefore, these terms should not be construed as limiting this application.

[0066] The foregoing disclosures are merely preferred embodiments of the present application and should not be construed as limiting the scope of the claims of the present application. A person skilled in the art will understand that implementing all or part of the steps of the foregoing embodiments and bringing about equivalent modifications in accordance with the claims of the present application still falls within the scope of the present application.
