Description

Technical Field

[0001] The utility model belongs to the field of automobile thick-wall parts, and in particular relates to a thick-wall part structure with optimized bright spots. Background Art

[0002] At present, in order to ensure the visual effect of the front and rear combination lights, automobile lights adopt a thick-walled structure with optical patterns on them. In order to achieve a reasonable process effect of mold and injection molding, smooth surfaces are required on the four sides of the pattern edge, and the smooth surface is not designed with a pattern surface. This smooth surface causes bright spots or bright lines to appear when the thick-walled parts are lit, which is different from the lighting effect of the pattern area, affecting the lighting effect of the front and rear combination lights. Utility Model Content

[0003] In order to solve the above problems existing in the prior art, the utility model provides a thick-walled component structure with optimized bright spots, and designs the smooth surface on the back of the optical pattern surface to improve the light output effect.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a thick-walled component structure with optimized bright spots, comprising a thick-walled component, a horizontal light guide block is arranged on the thick-walled component, an optical patterned surface is arranged at the front end of the light guide block, the optical patterned surface is entirely optically patterned, and a smooth surface is arranged on the light guide block and behind the optical patterned surface.

[0005] Furthermore, a light output head is arranged at the front end of the light guide block, the optical patterned surface is arranged in front of the light output head, the glossy surface is arranged on the outer circumference behind the light output head, the glossy surface protrudes outward from the outside of the light guide block, and the optical patterned surface is opposite to the light guide block below the light output head and has the same area.

[0006] Furthermore, the dimension of the light surface protruding from the outside of the light guide block is d, and d is between 0.1-0.2 mm.

[0007] Compared with the prior art, the utility model has the following beneficial effects: the utility model has a simple and ingenious structure, and the smooth surface is designed on the back of the optical pattern surface, so that there are no bright spots or bright lines on the surface of the thick-walled parts that affect the lighting effect. At the same time, the design of the smooth surface can also meet the reasonable process required by the mold and injection molding; in addition, the utility model designs the optical pattern surface and the light guide block below to have the same area and relative positions, so that the light output effect will not be affected.

[0011] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0012] See also Figure 1-3 The technical solution provided by the utility model is: a thick-walled component structure for optimizing bright spots, including a thick-walled component 1, a horizontal light guide block 3 is arranged above the thick-walled component 1, an optical pattern surface 2 is arranged at the front end of the light guide block 3, and the optical pattern surface 2 is a light emitting surface. The light is emitted through the pattern on the optical pattern surface 2, thereby achieving a uniform lighting effect. The optical pattern surface 2 is entirely optical patterns, which further improves the uniform lighting effect of the car lights, and there will be no different bright spots or bright lines. A light surface 31 is arranged on the light guide block 3 and behind the optical pattern surface 2, so as to meet the reasonable process required for the mold and injection molding.

[0013] Specifically, a light head 32 is provided at the front end of the light guide block 3, the optical patterned surface 2 is provided in front of the light head 32, the light surface 31 is provided on the outer peripheral circle behind the light head 32, the light surface 31 protrudes from the outside of the light guide block 3, and the side surface of the light head 32 is an inclined surface inclined from the front to the outside of the back. The setting of the light head 32 is to change the places on the four sides of the optical patterned surface 2 that were originally reserved for not designing patterns in order to achieve the reasonable process effect of the mold and injection molding to the back of the optical patterned surface 2. This also meets the reasonable process required for the mold and injection molding, and at the same time can further improve the uniform lighting effect of the car lights, and there will be no different bright spots or bright lines. The optical patterned surface 2 is directly opposite to the light guide block 3 below the light head 32 and has the same area, so that the light will be emitted according to the original light output path, avoiding the light output effect being affected by changing the position of the light surface 31.

[0014] Specifically, the dimension of the light surface 31 protruding from the outside of the light guide block 3 is d, and d is between 0.1-0.2 mm, which can meet the process requirements of the mold and injection molding.

[0015] Usually, a car lamp will use a thick-walled part 1, and the thick-walled part 1 will reserve a place without a pattern around the optical pattern surface 2 to meet the process requirements of the mold and injection molding. However, this place will cause the thick-walled part 1 to have a bright spot or bright line that is different from the lighting effect of the pattern surface area when it is lit. When the optical uniformity requirement is high, it cannot meet the needs of customers. Therefore, the utility model improves this defect, designs the optical pattern surface 2 to be all patterned, and designs a light surface 31 behind the optical pattern surface 2. The light surface 31 is arranged on the outer peripheral circle behind the light head 32, and the light surface 31 protrudes from the outside of the light guide block 3 by 0.1-0.2mm. In this way, the design of the light surface 31 can meet the process requirements of the mold and injection molding, and the design of the optical pattern surface 2 can improve the uniformity of the bright spot of the car lamp and meet the customer's higher requirements for optical uniformity. The structural design of the utility model is ingenious, and the optical pattern surface 2 and the light guide block 3 are designed to be opposite and have the same area, which will not affect the light output path of the original light, but will only improve the uniformity of the light output on the original basis.

[0016] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
