Description

Technical Field

[0001] The present application relates to the technical field of vehicle lamps, and more specifically, to a lampshade structure, a vehicle lamp, and a vehicle. Background Art

[0002] Currently, the industry generally uses a red inner lampshade made of PMMA (polymethyl methacrylate) material to achieve the steering function. However, when PMMA comes into contact with certain organic solvents, its surface easily swells and cracks, making it difficult to use spray painting or laser engraving. In addition, due to PMMA's poor impact resistance, it has limitations in assembly methods, making it difficult for a red inner lampshade made of PMMA to meet the functional requirements of steering.

[0003] Therefore, how to meet the requirements of the steering function of the vehicle lights has become a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0004] In view of this, the purpose of this application is to provide a lampshade structure to meet the requirements of the steering function of the vehicle lamp.

[0005] Another object of the present application is to provide a vehicle lamp having the above-mentioned lampshade structure.

[0028] The core of this application is to provide a lampshade structure to meet the requirements of the steering function of the vehicle lamp.

[0029] Another core of the present application is to provide a vehicle lamp having the above-mentioned lampshade structure.

[0030] Another core of the present application is to provide a vehicle having the above-mentioned headlight.

[0031] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0032] like Figure 1 As shown, an embodiment of the present application discloses a lampshade structure comprising an outer lampshade 100 and an inner lampshade assembly 200. By sequentially stacking the outer lampshade 100, the first inner lampshade 201, and the second inner lampshade 202, and by using a red transparent PC material for the first inner lampshade 201, light emitted by the light-emitting module 300 can sequentially pass through the second inner lampshade 202, the laser-engraved pattern 2011 of the first inner lampshade 201, and the outer lampshade 100, thereby meeting the requirements of the vehicle's steering function. Furthermore, compared to red PMMA materials used for steering functions, the red transparent PC material can improve the impact resistance of the inner lampshade and facilitate subsequent surface treatment. This allows the red transparent PC material to meet the optical requirements of the steering function while being suitable for a variety of assembly methods.

[0033] The following will be combined Figure 1 and Figure 2 The lampshade structure disclosed in the embodiment of the present application is specifically explained and illustrated.

[0034] Among them, such as Figure 1 As shown, the inner lampshade assembly 200 can be disposed between the outer lampshade 100 and the light-emitting module 300. The inner lampshade assembly 200 includes a first inner lampshade 201 and a second inner lampshade 202. The first inner lampshade 201 is stacked on the second inner lampshade 202 on the side closest to the outer lampshade 100. The first inner lampshade 201 can be made of red transparent PC material and has a laser-engraved pattern 2011 on it. This allows light emitted by the light-emitting module 300 to sequentially pass through the second inner lampshade 202, the laser-engraved pattern 2011 on the first inner lampshade 201, and the outer lampshade 100, thereby meeting the requirements of the vehicle light's steering function.

[0035] It will be understood by those skilled in the art that the red transparent PC material (polycarbonate) has better impact resistance than the traditional red PMMA material, which can make the first inner lampshade 201 easier to process the surface, thereby making the red transparent PC material suitable for a variety of assembly methods while meeting the optical requirements of the steering function.

[0036] In some embodiments, as Figure 1 and Figure 2As shown, the first inner lampshade 201 and the second inner lampshade 202 can be connected by a snap-fit connection. Specifically, a plurality of hooks 2014 can be provided on both sides of the first inner lampshade 201, while bayonet holes 2023 that mate with the hooks 2014 are provided on both sides of the second inner lampshade 202. When assembling the first and second inner lampshades 201, the hooks 2014 of the first inner lampshade 201 can be inserted into the bayonet holes 2023 of the second inner lampshade 202, thereby achieving a snap-fit connection between the first and second inner lampshades 201, 202. Of course, the bayonet holes 2023 can also be provided on the first inner lampshade 201, while the hooks 2014 are located on the second inner lampshade 202, thereby achieving a snap-fit connection between the first and second inner lampshades 201, 202. It should be noted that, in order to facilitate the insertion of the hook 2014 into the slot 2023, the hook 2014 has an inclined guide surface so that the hook 2014 can be inserted into the slot 2023 through the guide surface. In addition, there can be one or more hooks 2014 on each side of the first inner lampshade 201, and the slot 2023 is adapted to fit the hooks 2014.

[0037] In order to facilitate the installation of the first inner lampshade 201 and the second inner lampshade 202, in some embodiments, as shown in FIG. Figure 1 and Figure 2 As shown, the first inner lampshade 201 includes a first positioning portion 2012 and first inner lampshade surfaces 2013 located on either side of the first positioning portion 2012. Meanwhile, the second inner lampshade 202 includes a second positioning portion 2021 and second inner lampshade surfaces 2022 located on either side of the second positioning portion 2021. The first inner lampshade surface 2013 mates with the second inner lampshade surface 2022. In this embodiment, the first inner lampshade surface 2013 may be formed with a bend, giving the first inner lampshade 201 an "M"-shaped structure. Meanwhile, the second inner lampshade surface 2022 includes a protruding surface that mates with the bend of the first inner lampshade surface 2013, thereby ensuring that the first inner lampshade surface 2013 mates with the second inner lampshade surface 2022, making the lampshade structure more compact. Of course, the first inner lampshade surface 2013 may also be a planar structure or other structural shapes, which are not limited herein. During installation, the first positioning portion 2012 of the first inner lampshade surface 2013 and the second positioning portion 2021 of the second inner lampshade surface 2022 cooperate in a concave-convex manner to achieve assembly and positioning of the first inner lampshade 201 and the second inner lampshade 202, thereby preventing the first inner lampshade 201 and the second inner lampshade 202 from shifting during installation. Specifically, the first positioning portion 2012 can be a protrusion facing the outer lampshade 100 to form a tapered cavity on the side of the first inner lampshade 201 facing away from the outer lampshade 100. At the same time, the second positioning portion 2021 can be a tapered protrusion that cooperates with the tapered cavity. By inserting the tapered protrusion of the second inner lampshade 202 into the tapered cavity of the first inner lampshade 201, the first inner lampshade 201 and the second inner lampshade 202 are positioned and installed.

[0038] In order to prevent the first inner lampshade 201 and the second inner lampshade 202 from rotating during installation, one or more ridges may be provided in the circumferential direction of the conical protrusion of the second inner lampshade 202, and at the same time, grooves cooperating with the ridges may be provided in the circumferential direction of the conical cavity wall of the first inner lampshade 201, so that the ridges on the second inner lampshade 202 may cooperate with the grooves of the first inner lampshade 201 to limit the rotation of the first inner lampshade 201 and the second inner lampshade 202.

[0039] It should be noted that, in the above embodiment, the first inner lampshade 201 and the second inner lampshade 202 may also be connected by fasteners such as bolts, which will not be described in detail herein.

[0040] In some embodiments, as Figure 2 As shown, the laser engraved pattern 2011 may include a plurality of geometric figures disposed on the first inner lampshade surface 2013, i.e., one or more geometric figures may be used. The geometric figures may include at least one of a triangle, a circle, and a rectangle, i.e., the geometric figures may be solely triangles, circles, or rectangles, or a combination of triangles, circles, and rectangles. In this embodiment, the laser engraved pattern 2011 may utilize a plurality of triangular figures, each of which is arranged in an array. The triangular figures may be identical, or may be of different sizes and the same shape, or the same size and different shape, or of different sizes and shapes. It should be noted that in the above embodiment, the laser engraved pattern 2011 may also utilize other figures, which are not limited herein.

[0041] It should be noted that, in the above embodiment, the outer lampshade 100 and the second inner lampshade 202 can be made of transparent PC material or transparent PMMA material.

[0043] In the above embodiment, the vehicle lamp further comprises a lamp housing, and the light-emitting module 300 comprises a PCB board 301 and LED particles 302 arranged on the PCB board 301. The LED particles 302 are arranged corresponding to the laser-engraved pattern 2011, that is, each triangular figure corresponds to an LED particle 302, so as to achieve the lighting effect of the laser-engraved pattern 2011. Among them, the PCB board 301, the outer lampshade 100 and the inner lampshade assembly 200 are respectively fixed to the lamp housing. Specifically, the PCB board 301 can be fixed to the lamp housing by a bracket, and can be fixed by fasteners such as screws or a snap-on method. At the same time, the outer lampshade 100 and the inner lampshade assembly 200 can be fixed to the lamp housing by fasteners such as screws or a snap-on method. It should be noted that the connection method of the PCB board 301, the outer lampshade 100 and the inner lampshade assembly 200 to the lamp housing is similar to that in the prior art and will not be repeated herein.
