Description

Technical Field

[0001] This application relates to the field of vehicle technology, specifically to a lamp and a vehicle. Background Technology

[0002] Vehicle lighting fixtures, such as through lights that extend and run through the width of the vehicle, can enhance aesthetics while providing illumination, thus meeting the diverse needs of users.

[0003] The housing of a lamp typically consists of two parts, which are bonded together to form a mounting cavity for the light-emitting part. However, since the lamp is placed in a vehicle, the structural stability and sealing between the two parts of the housing cannot be guaranteed after long-term use. If moisture enters the housing, it will cause water mist to form inside the housing, affecting the lighting effect and thus the user experience.

[0004] Therefore, for vehicle-mounted lights, ensuring the overall structural stability and sealing of the lights, as well as guaranteeing the lighting effect and improving the user experience, are technical problems that urgently need to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this application is to provide a lamp and vehicle that can ensure the overall structural stability and sealing of the lamp, guarantee the lighting effect of the lamp, and improve the user experience.

[0006] To solve the above-mentioned technical problems, this application provides a lamp, including a housing and a light-emitting part disposed in the housing; the housing includes a first housing and a second housing, the first housing includes a first edge, the second housing includes a second edge, one of the first edge and the second edge is provided with a circumferential protrusion, and the other is provided with a circumferential recess, the first edge and the second edge are engaged and bonded together by the protrusion and the recess.

[0007] The protrusion is at least partially inserted into the recess, forming a labyrinthine sealing structure from the outside to the inside between the first edge and the second edge. Combined with adhesive bonding, this ensures the seal between the first edge and the second edge, preventing external dust, water, etc., from entering the mounting cavity through the gap between the first edge and the second edge. This keeps the mounting cavity clean and dry, thus preventing damage to the light-emitting part located in the mounting cavity. It also prevents moisture from entering the mounting cavity, which could cause fogging on the inner walls of the first and second housings when the ambient temperature is low, affecting the lighting effect of the lamp. This effectively improves the user experience.

[0008] Furthermore, since the protrusion is at least partially located within the recess and is fixed by adhesive bonding, the bonding area between the first edge and the second edge can be increased, thereby ensuring the bonding stability and the structural stability of the housing. Even if the lamp is exposed to the outside of the vehicle for a long time, the service life of the lamp can be effectively extended.

[0009] Optionally, the first housing includes a light-transmitting substrate, the surface of which is provided with a light-shielding coating, and a portion of the surface of the light-transmitting substrate is provided with a laser-engraved area, the surface of which is provided with a light-transmitting protective layer and forms a light-transmitting area.

[0010] Optionally, the light-shielding coating and the laser-engraved area are both disposed on the inner surface of the first housing, and the light-transmitting protective layer is disposed on both sides of the light-transmitting area.

[0011] Optionally, the light-shielding coating and the laser-engraved area are both located on the outer surface of the first housing, and the light-transmitting protective layer is provided on the outer surface of the light-transmitting area.

[0012] Optionally, both the first housing and the second housing are single-layer injection molded parts.

[0013] Optionally, the second housing has an extension on one side wall away from the first housing, and the extension has bolt mounting holes.

[0014] Optionally, the second housing may also be integrally formed with a fixing post, the fixing post having a threaded hole, or the fixing post having a stud pre-embedded in it.

[0015] Optionally, it also includes a seal disposed on the outer peripheral wall of the second housing.

[0016] Optionally, the seal is integrally injection molded with the second housing.

[0017] This application provides a vehicle including the lamps described above.

[0018] Vehicles equipped with the aforementioned lights have similar technical effects to those lights, and will not be described in detail here to save space. Attached Figure Description

[0029] To enable those skilled in the art to better understand the technical solutions of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] This application provides a lighting fixture and a vehicle, wherein the vehicle includes the aforementioned lighting fixture 10, as shown below. Figure 1 As shown, the vehicle also includes a hood 20, with a light fixture 10 connected to the hood 20. Of course, the light fixture 10 can also be installed in other locations on the vehicle, such as the top, rear, or side doors.

[0031] like Figure 2 As shown, the lamp 10 specifically includes a housing 1 and a light-emitting part 2. The housing 1 includes two housing parts: a first housing 11 and a second housing 12. The first housing 11 and the second housing 12 are circumferentially sealed and fixed together, and a mounting cavity is formed between the first housing 11 and the second housing 12. The light-emitting part 2 is installed in the mounting cavity.

[0032] The first housing 11 includes a first edge 111 arranged circumferentially, and the second housing 12 includes a second edge 121 arranged circumferentially. The first edge 111 and the second edge 121 are sealed and fixed circumferentially, and as shown... Figure 3 As shown, the first edge 111 has a circumferentially recessed portion 13, and the second edge 121 has a circumferentially protruding portion 14. After the first housing 11 and the second housing 12 are closed, the protruding portion 14 is located within the recessed portion 13, and the first edge 111 and the second edge 121 are also fixed together by adhesive. Of course, it is also possible for the first edge 111 to have a protruding portion 14 and the second edge 121 to have a circumferentially recessed portion 13; no specific limitation is made here.

[0033] The protrusion 14 is at least partially inserted into the recess 13, forming a labyrinthine sealing structure from the outside to the inside between the first edge 111 and the second edge 121. Combined with adhesive bonding, this ensures the seal between the first edge 111 and the second edge 121, preventing external dust and water from entering the mounting cavity through the gap between the first edge 111 and the second edge 121. This keeps the mounting cavity clean and dry, preventing damage to the light-emitting part 2 located within the mounting cavity. It also prevents moisture from entering the mounting cavity, which could cause fogging on the inner walls of the first housing 11 and the second housing 12 at low ambient temperatures, affecting the lighting effect of the lamp and thus effectively improving the user experience. Here, "outside" refers to the side outside the mounting cavity, and "inside" refers to the side facing inwards from the mounting cavity.

[0034] Furthermore, since the protrusion 14 is at least partially located within the recess 13 and is fixed by adhesive bonding, it can also increase the bonding area between the first edge 111 and the second edge 121, thereby ensuring the bonding stability and the structural stability of the housing. Even if the lamp 10 is exposed to the outside of the vehicle for a long time, it can effectively extend the service life of the lamp 10.

[0035] In this embodiment, both the first shell 11 and the second shell 12 are single-layer structural components, specifically single-color injection molded parts, which makes the overall thickness of the first shell 11 and the second shell 12 relatively thin. Compared with the solution of forming a double-layer structure shell through a two-color injection molding process, the structural strength of the first shell 11 and the second shell 12 is relatively weak.

[0036] When the lamp 10 is installed on the hood 20 of a vehicle, it can reduce the injury to the human body caused by the lamp 10 and improve safety if the vehicle collides with a pedestrian.

[0037] Furthermore, since the first edge 111 and the second edge 121 are bonded together by the convex part 14 and the concave part 13, the installation stability at the edge of the shell part 1 can be guaranteed even when the thickness is relatively thin.

[0038] like Figure 2 As shown, the second housing 12 is positioned facing the side of the vehicle, while the first housing 11 is exposed. From the outside, the first housing 11 is visible, but the second housing 12 is not. The first housing 11 is provided with a light-transmitting area 112 and a light-shielding area 113. The light emitted by the light-emitting part 2 can pass through the light-transmitting area 112, and the light-shielding area 113 can block the light, thereby enabling a beam of light with a special shape to be seen from the outside, so as to meet the diverse needs of users and improve the user experience.

[0039] Specifically, the first housing 11 includes a light-transmitting substrate, which can be a light-transmitting PP (Polypropylene) sheet, a light-transmitting PC (Polycarbonate) sheet, or a light-transmitting PMMA (polymethyl methacrylate) sheet, etc. A portion of the light-transmitting substrate has a light-shielding layer on its surface to form the aforementioned light-shielding area 113, while the remaining portion of the light-transmitting substrate does not have a light-shielding layer on its surface, forming a light-transmitting area 112. The light-shielding layer can be a light-shielding coating sprayed onto the surface of the light-transmitting substrate, and the color of the coating can be customized according to user needs to meet diverse user requirements and enhance the user experience.

[0040] The area without a light-shielding coating can be formed by shielding it with a shielding component when spraying the light-shielding coating onto the light-transmitting substrate surface, so that this area is not sprayed with the light-shielding coating, or by spraying the light-shielding coating onto the entire light-transmitting substrate surface and then removing part of the light-shielding coating through laser engraving or other processes to restore its light-transmitting properties, thereby forming the light-transmitting area 112.

[0041] Preferably, after spraying a light-shielding coating onto the entire surface of the light-transmitting substrate, a portion of the light-shielding coating is removed using a laser engraving process to form the light-transmitting area 112. This makes the boundary of the light-transmitting area 112 more regular, avoids the presence of rough edges, and ensures the regularity of the light beam transmitted from the light-emitting part 2 through the light-transmitting area 112 when it is emitting light, thereby improving the user experience.

[0042] The surface of the laser-engraved area formed by laser engraving may be uneven. Therefore, a light-transmitting protective layer is also set on the surface of the laser-engraved area. This layer is a protective varnish to make the surface of the light-transmitting area 112 smooth and avoid affecting the emission of light.

[0043] The light-shielding coating can be applied to the surface of the first housing 11 facing the second housing 12, i.e., the inner surface of the first housing 11, or the light-shielding coating can be applied to the outer surface of the first housing 11 away from the second housing 12. The laser-engraved area and the light-shielding coating are located on the same side of the first housing 11.

[0044] In detail, when the light-shielding coating is applied to the inner surface of the first housing 11, the laser-engraved area is also located on the inner surface of the first housing 11. At this time, the inner and outer surfaces of the light-transmitting area 112 are respectively provided with light-transmitting protective layers. The light-transmitting protective layer on the inner surface can make the surface of the laser-engraved area relatively flat and reduce the influence on light. The light-transmitting protective layer on the outer surface can provide protection for the light-transmitting area 112 from the outside.

[0045] When the light-shielding coating is applied to the outer surface of the first housing 11, the laser-engraved area is located on the outer surface of the first housing 11. At this time, the surface of the light-transmitting substrate facing the second housing 12 is smooth and flat, and there is no problem of uneven surface caused by laser engraving. Furthermore, the mounting cavity inside the housing 1 is in a sealed state. Therefore, it is sufficient to apply a light-transmitting protective layer only to the surface of the laser-engraved area outside the light-transmitting area 112.

[0046] In other words, the laser-engraved area and the light-shielding coating are located on the same side surface of the light-transmitting substrate. They can be located on the inner or outer surface of the light-transmitting substrate, depending on the actual situation, offering good flexibility. Furthermore, the surface of the laser-engraved area is also provided with a light-transmitting protective layer, and the outer surface of the light-transmitting area 112 is also provided with a light-transmitting protective layer. This protects the surface of the light-transmitting area 112 and prevents it from affecting the transmitted light.

[0047] Of course, in this embodiment, the first housing 11 can also be configured to include a light-transmitting substrate and a light-shielding plate. The light-transmitting substrate can be made of light-transmitting PP (Polypropylene), PC (Polycarbonate), or PMMA (polymethyl methacrylate), etc., while the opaque substrate can be made of any opaque material, such as opaque PP, PC, or PMMA. The light-transmitting substrate and the light-shielding plate are assembled to form the first housing 11. When the first housing 11 is configured as a one-piece molded structure, the molding process of the first housing 11 can be simplified, the installation operation can be simplified, and the sealing performance and structural stability of the first housing 11 can be guaranteed.

[0048] Furthermore, in this embodiment, there are no specific limitations on the light-emitting part 2 located within the mounting cavity, such as... Figure 2 As shown, the light-emitting part 2 includes a light-emitting element 21 and a reflector 22. The light-emitting element 21 can be an LED light, laser light, etc. The light-emitting side of the light-emitting element 21 is positioned facing the reflector 22. After the light emitted by the light-emitting element 21 shines on the reflector 22, it is reflected by the reflector 22 and then transmitted through the light-transmitting area 112. This ensures that the light transmitted through the light-transmitting area 112 is a relatively regular straight beam, avoiding the divergence of the light transmitted through the light-transmitting area 112, improving the visual effect, and thus enhancing the user experience. Specifically, how to set the reflector 22 to reflect the light emitted by the light-emitting element 21 and make the reflected light transmit through the light-transmitting area 112 is already well known prior art to those skilled in the art, and will not be described in detail here for the sake of brevity.

[0049] Furthermore, after being reflected by the reflector 22, the light is transmitted through the light-transmitting area 112. The light-emitting element 21 and the lines connected to the light-emitting element 21 will not be visible from outside the light-transmitting area 112, thereby improving the overall neatness and aesthetics and further enhancing the user experience.

[0050] In this embodiment, the position between the lamp 10 and the hood 20 is not specifically limited, such as... Figure 1 As shown, the light fixture 10 can be located at the rear end of the hood 20, that is, the end facing the windshield 30, or it can be as follows: Figure 4 As shown, the light fixture 10 is located at the front end of the hood 20, that is, on the side away from the windshield. The specific location can be adjusted according to the actual situation. Preferably, the light fixture 10 is located at the rear end of the hood 20 to avoid the light fixture 10 causing leg injury in the event of a collision.

[0051] Taking the lamp 10 located at the rear end of the front hood 20 as an example, Figure 2 As shown, a groove 210 is provided at the edge of the hood 20, and the lamp 10 is located in the groove 210. The housing 1 of the lamp 10 is fixed to the groove wall of the groove 210. In the installed state, the height of the outer surface of the first housing 11 corresponds to the height of the outer surface of the hood 20, so that the outer surface of the first housing 11 and the outer surface of the hood 20 are roughly streamlined, avoiding the lamp 10 from protruding or being recessed excessively relative to the outer surface of the hood 20, thereby making the overall shape of the vehicle more regular.

[0052] The lamp also includes a sealing element 3, which is disposed on the outer peripheral wall of the housing 1. In the installed state, the sealing element 3 is located between the groove side wall 212 of the groove 210 and the side wall of the housing 1 (specifically the side wall of the second housing 1) to ensure the sealing between the housing 1 and the groove side wall 212 of the groove 210. At the same time, it can also avoid the gap between the two being too large, which would lead to problems such as poor overall structural consistency and poor aesthetics.

[0053] In this embodiment, the sealing element 3 and the sidewall of the second housing 12 are integrally injection molded. Of course, the sealing element 3 can also be set as a separate structure and installed separately. When the sealing element 3 and the second housing 12 are integrally molded, the lamp 10 can be directly placed in the mounting cavity and fixed during installation, without the need to install the sealing element 3 separately, thereby simplifying the number of parts and the installation operation.

[0054] Specifically, there are no restrictions on the specific fixing method of the lamp 10 and the front hood 20. To ensure installation stability, the shell 1 and the groove wall of the recess 210 are fixed together by fasteners. Along the front-rear direction of the vehicle, the shell 1 can be fixed to the groove wall of the recess 210 by two rows of fasteners, or the shell 1 can be fixed to the groove wall of the recess 210 by one row of fasteners. At the same time, the shell 1 is also fixed to the groove wall of the recess 210 by a row of snap-fit ​​structures. In this way, the installation operation is simplified while ensuring installation stability.

[0055] Of course, the shell 1 and the groove wall of the groove 210 can also be fixed by adhesive bonding, combined with fasteners to ensure the stability of the fixation. The combination of snap-fit ​​fixing and fastener fixing can also facilitate the disassembly operation between the lamp 10 and the front cover 20, thereby facilitating the maintenance and replacement of the lamp 10.

[0056] Specifically, there are no restrictions on the snap-fit ​​fixing method. The shell part 1 is provided with a snap protrusion and the groove wall of the groove 210 is provided with a snap groove, or the groove wall of the groove 210 is provided with a snap protrusion and the shell part 1 is provided with a snap groove.

[0057] For the bolt 4 fixing method, such as Figure 2 As shown, the second housing 12 has an extension 15 on the side wall away from the first housing 11. The extension 15 has a bolt mounting hole, which can be a through hole or a threaded hole. During installation, the bolt 4 passes through the bottom wall 211 of the groove 210 and is fixed by threaded engagement with the bolt mounting hole. Alternatively, the bolt 4 can pass through the groove 210, the bottom wall 211, and the bolt mounting hole and be fixed by a nut.

[0058] Alternatively, the second housing 12 may be integrally formed with a fixing post that protrudes into the mounting cavity and has a threaded hole. The bolt 4 passes through the bottom wall 211 of the groove 210 and is threadedly engaged with the threaded hole for fixation. Alternatively, a stud may be pre-embedded in the fixing post. During installation, the stud passes through the bottom wall 211 of the groove 210 and is engaged with a nut for fixation.

[0059] The extension 15, the fixing post, and the bolt 4 are used to fix the front cover 20, which can ensure the stability of the fixation while facilitating disassembly and assembly. At the same time, the bolt 4 is located outside the mounting cavity, so there is no need to set up additional sealing components to ensure the overall sealing of the shell 1.
