Description

Technical Field

[0001] This utility model relates to the field of automotive lamp housing technology, specifically to a vehicle lamp housing that facilitates stable sealing. Background Technology

[0002] Automotive headlights are mainly composed of a lamp housing, a lamp cover, and a light-emitting element. The light-emitting element is generally installed in the mounting groove of the lamp housing, while the lamp cover and the lamp housing are connected by sealant to ensure that the lamp cover and the lamp housing can form a sealed space.

[0003] For example, Chinese patent document CN210014314U discloses a lamp housing and an automobile, including: a lamp housing body and a glue groove. The glue groove is provided around the edge of the mounting surface of the lamp housing body. The glue groove includes a side wall, a bottom wall, and a glue groove opening formed by the side wall. Multiple mounting feet are provided along the extension trajectory of the glue groove. The mounting feet include a connecting part and a mounting plate. The connecting part includes a first connecting plate, a second connecting plate, and a third connecting plate connected in sequence. The first connecting plate, the second connecting plate, and the third connecting plate form an opening groove. The first connecting plate is connected to the side of the bottom wall away from the glue groove opening. The end of the third connecting plate away from the second connecting plate is connected to the mounting plate. The mounting plate is used to connect to the vehicle body.

[0004] As disclosed above, in the aforementioned technical solution, when connecting the lampshade and the lamp housing body, sealant is applied to the adhesive groove, allowing the lampshade to be placed over the lamp housing body. Once the sealant solidifies, the lampshade and lamp housing body are fixed together. However, in actual assembly, it was found that the amount of sealant applied depends primarily on the width of the adhesive groove. Since the width of the groove is constant, the amount of sealant applied at the junction of the lampshade and the lamp housing body is limited, thus affecting the sealing stability between them. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a vehicle lamp housing that is easy to seal stably, which can improve the sealing performance of the connection between the lamp cover and the lamp housing body.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vehicle lamp housing that facilitates stable sealing, comprising a lamp housing body, wherein the lamp housing body is provided with a mounting groove for mounting a light-emitting component, the end face of the lamp housing body is provided with a glue groove surrounding the mounting groove, the inner wall of the lamp housing body is provided with a protruding frame, the frame being multiple and spaced apart from each other along the path of the glue groove, and a cavity for increasing the amount of sealant applied in the glue groove is formed between the frame and the glue groove, the cavity being connected to the glue groove.

[0007] The present invention is further configured such that: a baffle is provided on the outer periphery of the lamp housing body, and the baffle is provided in multiple ways and spaced apart from each other along the outer extension of the lamp housing body; the baffle is used to laterally limit the lampshade connected to the end face of the lamp housing body.

[0008] The present invention is further configured such that: the baffle includes a fixing part and a limiting part, the fixing part is fixed to the outer wall of the lamp housing body, and the limiting part and the fixing part are detachably connected.

[0009] The present invention is further configured such that: the fixing part is provided with a sliding groove, the bottom end of the limiting part is provided with a protruding slider, the slider is coupled to the sliding groove, and can form a sliding fit between the two.

[0010] The present invention is further configured such that: the outer wall of the slider is provided with a protruding locking block, the locking block being used to improve the stability of the connection between the fixing part and the limiting part.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] By incorporating multiple frames distributed along the adhesive groove on the inner wall of the lamp housing, these frames create cavities that increase the amount of sealant applied within the groove. After the sealant is injected into the groove, it extends along these cavities, forming multiple laterally widened bonding points. This increases the contact area between the lampshade and the lamp housing when bonding them, improving the connection stability and ensuring a tight seal. Therefore, this effectively solves the technical problem in existing technologies where the limited amount of sealant applied at the junction of the lampshade and the lamp housing affects the sealing stability. Furthermore, this solution avoids directly widening the entire adhesive groove laterally to increase the contact area, thus preventing the need for a thicker lampshade to accommodate the sealant width, which would increase the light transmittance requirements of the light-emitting element.

[0017] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] like Figures 1 to 4 As shown, this utility model discloses a vehicle lamp housing that facilitates stable sealing, including a lamp housing body 1. The lamp housing body 1 is provided with a mounting groove 101 for installing a light-emitting component. The open end face of the mounting groove 101 is provided with a glue groove 102 extending circumferentially around the mounting groove 101. The glue groove 102 is used to fill sealant to achieve a sealed connection between the lamp housing body 1 and the lamp cover.

[0020] Inside the adhesive groove 102 (on the side near the mounting groove 101), the inner wall of the lamp housing body 1 is provided with multiple protruding frames 2. These frames 2 are spaced apart along the annular path of the adhesive groove 102, forming a cavity 21 between the frames 2 and the sidewall of the adhesive groove 1023. The cavity 21 communicates with the adhesive groove 102, allowing the sealant injected into the adhesive groove 102 to flow into the cavity 21. Therefore, after the sealant is injected into the adhesive groove 102, it extends along the direction of the cavity 21, forming multiple laterally widened bonding points. This increases the contact area between the lampshade and the lamp housing body 1 when bonding them, thereby improving the connection stability and ensuring the seal between them. In addition, the reason why this solution does not directly widen the glue groove 102 horizontally to increase the contact area between the lampshade and the lamp housing body 1 is that it can avoid the problem of increasing the light transmission requirements of the light-emitting element by thickening the lampshade to match the width of the sealant.

[0021] Furthermore, multiple baffles 3 are provided on the outer periphery of the lamp housing body 1, with each baffle 3 spaced apart along the outer edge of the lamp housing body 1. The baffles 3 are used to laterally limit the sides of the lamp cover, preventing horizontal displacement of the lamp cover after installation. The baffle 3 includes a fixing part 31 and a limiting part 32, wherein the fixing part 31 is fixed to the outer wall of the lamp housing body 1 by integral molding, and the limiting part 32 is connected to the fixing part 31 by a detachable connection structure. Specifically, a groove 311 is provided in the fixing part 31, and a slider 321 matching the groove 311 is provided at the bottom end of the limiting part 32. During installation, the slider 321 slides into the groove 311 to achieve quick assembly of the baffle 3 as a whole. Therefore, when connecting the lampshade to the lamp housing body 1, the limiting part 32 is first assembled to the fixing part 31, and then the lampshade is pressed down to squeeze the limiting part 32. Since the limiting part 32 is made of plastic, it will deform after being pressed. The elastic force generated by the deformation of the limiting part 32 can act on the lampshade to achieve lateral limiting of the lampshade. When replacing the lampshade, the limiting part 32 can be removed from the fixing part 31 first. This can avoid the limiting part 32 squeezing the lampshade and causing inconvenience in disassembling the lampshade.

[0022] In addition, a protruding locking block 4 is provided on the outer wall of the slider 321. When the slider 321 slides into the slide groove 311, the locking block 4 is squeezed by the inner wall of the slide groove 311 and undergoes elastic deformation. This can increase the friction generated by the contact between the slider 321 and the slide groove 311, improve the tightness of the connection between the slider 321 and the slide groove 311, thereby enhancing the connection stability between the fixing part 31 and the limiting part 32 and preventing the limiting part 32 from accidentally coming out.

[0023] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
