Description

Technical Field

[0001] The utility model relates to the technical field of lamps, in particular to a clamping structure for reverse glue application of lamps. Background Art

[0002] During the driving of a vehicle, automotive lamps have very important lighting functions and signal functions, and are the windows for the vehicle to interact with the external environment. In the design of automotive lamps, the lamp body of the front lamps is restricted by factors such as the styling design of the vehicle manufacturer's automotive lamps, the body-in-white structure, the grille styling, and the position of the vehicle body radar in new energy vehicle models. Therefore, designers must innovate the installation method of the internal parts of the lamps while meeting the requirements of the vehicle manufacturer's appearance styling. To meet the requirements of the vehicle manufacturer for the beautiful appearance and novel animation effect of the lamps, the front lamps are designed to have a smaller Z-direction space in the vehicle body for a more beautiful appearance, resulting in the inability to use screws to fix the light distribution mirror and the lamp body. Therefore, the form of reverse glue application is adopted. First, the lamp body is installed into the light distribution mirror. Generally, the lamp body and the light distribution mirror are roughly positioned together by a buckle, and then the reverse sides of the lamp body and the light distribution mirror are glued together with glue.

[0003] For reverse-glued lamps, due to the glue application form, it is not convenient to have a limiting structure in the X-direction, that is, the depth direction of the light distribution mirror. During the movement of the vehicle, the light distribution mirror and the lamp body may fall off. In particular, the lamp body is prone to shift to the reverse side of the light distribution mirror and to the opening side of the light distribution mirror. In view of this phenomenon, a clamping structure suitable for reverse-glued lamps is proposed to facilitate the limiting of the lamp body and the light distribution mirror to solve the technical problem that the lamp body is prone to shift to the reverse side of the light distribution mirror. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a clamping structure for reverse glue application of lamps that reduces the loosening phenomenon between the light distribution mirror and the lamp body.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A clamping structure for reverse glue application of lamps, including a light distribution mirror and a lamp body that are integrally pasted. One side of the light distribution mirror is open to surround the lamp body. The clamping structure further includes a plurality of protrusions fixed on the inner wall of the light distribution mirror. The side of the protrusion facing the lamp body is semi-circular arc-shaped;

[0007] The lamp body can be pressed by the protrusions and clamped into the interior of the light distribution mirror through the opening of the light distribution mirror.

[0008] Further, the radius of the side of the protrusion facing the lamp body is 0.5 mm.

[0009] Further, the length of the side of the protrusion facing the lamp body is 10 - 15 mm.

[0010] In the above technical solution, the utility model has the following beneficial effects:

[0011] The utility model provides a clamping structure for reverse glue application of a lamp, and a clamping structure is reserved at a suitable position in the light distribution mirror of the lamp. The clamping structure positions the lamp body through a protrusion, preventing the lamp body from shifting towards the opening direction of the light distribution mirror. The clamping connection between the light distribution mirror and the lamp body enables the lamp body to have a certain positioning in the X direction and the depth direction of the light distribution mirror. During the movement of the vehicle, the situation of the light distribution mirror and the lamp body falling off is reduced, and the glue consumption is reduced, thereby reducing costs.

[0018] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail in conjunction with the drawings.

[0019] It should be noted that the orientation or positional relationship indicated by the terms "above", "one end", "upper", etc. used in this article is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description. Similar expressions are only for the purpose of illustration and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model; in addition, the terms "one part", "two parts", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0020] As Figures 1-3A clamping structure for reverse glue application of a lamp, including a light distribution lens 1 and a lamp body 2 that are integrally pasted. The light distribution lens 1 has an opening on one side and is used to surround the lamp body 2. The outer surface of the lamp body 2 can be attached to the inner wall surface of the light distribution lens. It also includes a plurality of protrusions 3 fixed on the inner wall of the light distribution lens 1. The side of the protrusion 3 facing the lamp body 2 is semi-circular. The side of the protrusion 3 is a semi-circular curved surface. The contact gap between the protrusion 3 and the outer surface of the lamp body 2 decreases from large to small until extrusion occurs. After the outer surface of the lamp body 2 passes through the middle part of the side of the protrusion 3, the contact gap increases from small to large. In this way, the protrusion 3 restricts the lamp body 2 within the light distribution lens 1. The semi-circular shape will not scratch the lamp body 2.

[0021] The lamp body 2 can be clamped into the interior of the light distribution lens 1 through the extrusion of the protrusion 3 from the opening of the light distribution lens 1.

[0022] This new type has made technical improvements to the problem that the lamp body 1 may shift from the interior of the light distribution lens 1 towards the opening direction, causing the lamp body to become loose. By restricting the lamp body 2 within the light distribution lens through the protrusion 3, it can prevent glue from overflowing from the lamp body and causing vehicle appearance pollution, reduce the glue consumption, and lower the cost. Reserve a clamping structure with protrusions at an appropriate position in the light distribution lens of the lamp. The clamping structure of the light distribution lens is positioned with the lamp body as Figure 2 shown; the clamping of the light distribution lens and the lamp body enables the lamp body to be positioned in the X direction. During the vehicle movement process, the light distribution lens and the lamp body will not fall off.

[0023] Furthermore, the radius of the protrusion 3 is 0.5 mm. If the radius is too large, the outer surface of the lamp body 2 will be stuck on the protrusion 3 and cannot enter the interior of the light distribution lens. If the radius is too small, it cannot play the role of restricting the lamp body 2 within the light distribution lens.

[0024] Furthermore, the length of the protrusion 3 is 10 - 15 mm. Preferably, it is 12 mm.

[0025] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
