Description

Technical Field

[0001] The utility model relates to the field of lighting vehicle lamps, and more specifically, to a fixing structure between a decorative ring and a lampshade and a lamp thereof. Background Art

[0002] In the prior art, the connection method between the combined decorative ring and the lampshade is not stable enough. Since there are no ribs to fix the decorative ring and the diffuser cover, and the decorative ring and the diffuser cover are relatively large and thin, they are prone to deformation, and there is a risk of vibration, dislocation or abnormal noise. At the same time, the screw connection requires a large space.

[0003] Chinese patent CN201821380679.1 discloses a fixing structure of a combined headlight decorative frame and a lampshade, which realizes the clamping and fixing of the decorative frame and the lampshade by setting the lamp shell glue groove, the lampshade clamping groove, the decorative frame clamping groove and the melt glue. Compared with the traditional clamping or screw connection, this fixing method is more firm and stable, and saves installation space. However, the melt glue will gradually lose its viscosity over time and with vibration, resulting in light leakage and low efficiency of the melt glue.

[0004] In view of the deficiencies of the prior art, the present application aims to provide a fixing structure, which can achieve reliable connection in a narrow space, resist forces from multiple directions, and realize locking with multiple degrees of freedom. Summary of the invention

The two cooperate to achieve multi-degree-of-freedom positioning, thereby better resisting forces from multiple directions, maintaining a reliable connection, and avoiding the possibility of light leakage through gaps.

[0011] Preferably, the spacing between adjacent first limit buckles and second buckles is the same. The structure can evenly distribute stress on each engaging structure to avoid excessive stress on a local engaging structure.

[0012] Preferably, the locking structure comprises a third connecting ear on the lampshade and a screw hole column on the decorative ring, and the locking member connects the third connecting ear and the screw hole column. The screw hole on the third connecting ear is opposite to the screw hole column and is threadedly connected with a screw to achieve fixation.

[0013] Preferably, the first direction is the normal direction of the window.

[0014] Preferably, the first limiting buckle is arranged on the side wall of the decorative ring, and a limiting space for inserting the first limiting protrusion is provided below the first limiting buckle.

[0015] Preferably, the lampshade and the decorative ring are located on both sides of the window in the width direction, and the second direction is the width direction of the window.

[0016] Preferably, the second fastening member comprises two clips arranged along the length direction, and the grooves respectively abut against two side walls of the second groove in the length direction.

[0017] Preferably, the first limit buckle and the second buckle are integrated with the decorative ring; the first limit protrusion and the second groove are integrated with the lampshade. Compared with the connection form of the adhesive connection, the buckle structure has a longer life and strength.

[0018] A lamp comprises a decorative ring and a lampshade, wherein a fixing structure for fixing the decorative ring and the lampshade as described above is arranged between the decorative ring and the lampshade.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] (1) The device obtained by connecting in the form of snap-on and fasteners has reliable connection strength and adapts to narrow connection edges;

[0021] (2) The buckle structure can resist forces in multiple degrees of freedom, making the fixed structure more reliable;

[0022] (3) By first connecting the snap-fit ​​structure and then connecting the locking structure, installation is easier and more efficient. BRIEF DESCRIPTION OF THE DRAWINGS
