[0018] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0019] like Figures 1-4 As shown, a bracketless ambient light includes a lampshade fixing base 1 and a lampshade base 2 formed in the inner ring of the lampshade fixing base 1. The lampshade fixing base 1 has an installation gap 4 in the middle for mounting a light guide 3. Both the lampshade fixing base 1 and the lampshade base 2 are connected end to end in a ring structure. The light guide 3 rests on the ring structure of the lampshade base 2. The outer ring of the lampshade fixing base 1 has a lampshade buckle 11 for pressing the light guide 3.

[0020] The lampshade mounting bracket 1 and the lampshade base 2 are an integral structure. The lampshade base 2 is formed in the inner ring of the lampshade mounting bracket 1, and the lampshade mounting bracket 1 is located in the outer ring of the lampshade mounting bracket 1. The light guide 3 is installed along the annular length direction of the lampshade mounting bracket 1.

[0021] The light guide 3 is supported by the lampshade base 2 and pressed by the lampshade buckle 11, thus clamping the light guide 3 within the installation gap 4. Under the action of the ring structure lampshade base 2 and lampshade fixing seat 1 set according to actual needs, the light guide 3 is stably set along the length direction of the lampshade base 2.

[0022] The light guide 3 can be made of transparent PMMA or transparent PC material. The back of the light guide 3 has optical teeth, which are used to emit light from the light guide 3 to achieve the lighting effect of ambient light.

[0023] The lampshade base 2 includes a bottom support 21 and a side support 22 that is misaligned with the bottom support 21. A mounting position for placing the light guide 3 is formed between the bottom support 21 and the side support 22. The mounting position is located within the mounting gap 4.

[0024] The lampshade base 2 forms a stepped structure connected by a bottom support 21 and a side support 22. The light guide 3 is placed at the mounting position of the stepped structure lampshade base 2, and the bottom support 21 provides bottom support for the light guide 3.

[0025] The light guide 3 is placed on the bottom support 21, and the bottom support 21 has a bottom support rib 23 for reducing the contact area with the light guide 3. The bottom support rib 23 is arranged along the width direction of the installation gap 4, and the cross section of the bottom support rib 23 is arc-shaped.

[0026] The bottom support 21 supports the bottom of the light guide 3, thereby limiting the vertical movement of the light guide 3 within the installation gap 4. The bottom support rib 23 is a raised rib formed on the surface of the bottom support 21. The number of bottom support ribs 23 is set according to actual needs. The bottom support rib 23 supports the bottom of the light guide 3. At the same time, the bottom support rib 23 with an arc-shaped cross-section minimizes the contact area between the bottom support rib 23 and the light guide 3, thereby reducing the occlusion between the bottom support rib 23 and the light guide 3.

[0027] The bottom support rib 23 can be a semi-cylindrical or hemispherical structure. Under the action of the bottom support rib 23, the surface contact between the bottom support base 21 and the light guide 3 is changed to a line contact or point contact, which greatly reduces the contact area between the bottom support rib 23 and the light guide 3.

[0028] At the connection between the bottom support 21 and the side support 22, a side support rib 24 is formed to limit and support the side of the light guide 3. The side support rib 24 is connected to the bottom support rib 23, and the cross section of the side support rib 24 is arc-shaped.

[0029] Under the action of the side support seat 22, the side support seat 22 and the lamp cover fixing seat 1 are used to guide the irradiation direction of the light guide 3. At the same time, the side support seat 22 is used to support the side support rib 24, thereby realizing the horizontal positioning of the light guide 3 within the installation gap 4. The side support rib 24 is a convex rib formed at the connection between the bottom support seat 21 and the side support seat 22. The number of side support ribs 24 is set according to actual needs. Under the action of the side support rib 24, the light guide 3 is supported from the side. At the same time, under the action of the side support rib 24 with the arc-shaped cross section, the contact area between it and the light guide 3 is minimized as much as possible, thereby reducing the obstruction between the side support rib 24 and the light guide 3.

[0030] The side support rib 24 can be a semi-cylindrical or hemispherical structure. Under the action of the side support rib 24, the surface contact between the side support rib 24 and the light guide 3 is changed to a line contact or point contact, which greatly reduces the contact area between the side support rib 24 and the light guide 3.

[0031] The top of the light guide 3 has an installation entrance 5 located between the lamp cover mounting base 1 and the side support base 22, and a light-transmitting gap 6 connected to the installation entrance 5 is formed between the side support base 22 and the light guide 3.

[0032] The light-transmitting gap 6 is located at the installation entrance 5. Under the action of the light-transmitting gap 6, the light guide 3 does not contact the side support 22. When the lampshade at the side support 22 satisfies the requirement of uniform light output from the light guide 3, the contact between the side support 22 and the light guide 3 is reduced. The installation entrance 5 has an outwardly extending connecting protrusion 31 on the side of the light guide 3. The lampshade fixing seat 1 has a lampshade buckle 11 for pressing the connecting protrusion 31. Under the action of the lampshade buckle 11, the light guide 3 is pressed from top to bottom, and the light guide 3 is pressed on the bottom support 21. Thus, under the action of the lampshade fixing seat 1 and the lampshade base 2, a stable clamping installation of the light guide 3 is achieved.

[0033] The lamp cover mounting base 1 has several positioning pieces 12 formed on its outer side for fixing the lamp cover mounting base 1. Positioning holes 13 are formed on the positioning pieces 12. Bolts are installed in the positioning holes 13 to fix the lamp cover mounting base 1 to the vehicle frame.

[0034] In actual use, the lampshade fixing seat 1 is first set at the required position on the frame, and then the strip light guide 3 is installed to the installation gap 4 through the installation inlet 5. The light guide 3 is pressed down, and at the same time, the bottom of the light guide 3 abuts against the lampshade base 2. The light guide 3 is pressed tightly by the lampshade buckle 11. Under the support of the side support rib 24 and the bottom support rib 23 of the lampshade base 2, the spatial position of the light guide 3 is positioned and locked. The positioning piece 12 is locked on the frame by bolts to lock the lampshade fixing seat 1. At this time, the lampshade fixing seat 1 is in a relatively fixed state. The lampshade fixing seat 1 restricts the outward movement of the light guide 3. Under the structural strength of the ring structure of the lampshade base 2, the lampshade base 2 restricts the inward movement of the light guide 3. Under the action of the lampshade buckle 11 and the bottom support seat 21, the light guide 3 is limited in the vertical direction, so as to achieve stable installation of the light guide 3.

[0035] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention; therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.

[0036] Although this document frequently uses reference numerals from the accompanying drawings, such as lampshade fixing base 1, lampshade buckle 11, positioning piece 12, positioning hole 13, lampshade base 2, bottom support 21, side support 22, bottom support rib 23, side support rib 24, light guide 3, installation gap 4, installation entrance 5, and light transmission gap 6, the possibility of using other terms is not excluded.
