Description

Technical Field

[0001] This utility model relates to the field of ambient lighting technology, specifically to a single-source three-dimensional luminous cup holder ambient light. Background Technology

[0002] With the rapid advancement of automotive technology, more and more car models are incorporating ambient lighting to enhance the ambiance and premium feel of the car's interior.

[0003] Please refer to Chinese utility model patents with publication numbers CN223411915U and CN222629205U. The applicant in this case designed two different types of cup holder ambient lights. One type uses multiple light sources to form a relatively uniformly bright annular light-emitting band on the side wall of the cup holder, while the other uses a single light source to form multiple annular light-emitting bands at the bottom of the cup holder. However, regardless of the type of cup holder ambient light, its luminous area is very small, resulting in a lack of three-dimensional lighting effect and failing to meet customers' increasingly higher demands for ambient lighting effects. Utility Model Content

[0004] To address the technical problem that existing cup holder ambient lights cannot achieve a three-dimensional lighting effect, this utility model provides a single-source three-dimensional luminous cup holder ambient light.

[0005] The technical solution is as follows:

[0006] The first aspect of this application relates to a single-source three-dimensional luminous cup holder ambient light, including a cup holder and an ambient light optical assembly. The cup holder is a cylindrical structure with an opening at the top and is made of a light-transmitting material. The ambient light optical assembly includes a light guide and a lamp head. The light guide includes a linear light guide strip and a light guide tube adapted to the cup holder. The light guide tube has an annular light guide section that is cylindrically fitted on the circumferential outer wall of the cup holder. The annular light guide section gradually narrows at one end near the bottom of the cup holder to form a transition section that is integrated with the upper end of the light guide strip. The light guide tube has optical patterns distributed on at least the circumferential outer wall of the annular light guide section for guiding light to the cup holder. The lower end face of the light guide strip is a light-inlet face. The lamp head is located at the lower end of the light guide strip, and the light emission direction of the light source in the lamp head is directly facing the light-inlet face.

[0007] The above-mentioned single-source three-dimensional luminous cup holder ambient light utilizes a newly designed light guide and an overall translucent cup holder. Through the optical coordination of a single lamp head and the light guide, a large-area ambient lighting effect can be achieved on the side wall of the cup holder, thus achieving a large-area three-dimensional luminous effect. This not only meets customers' increasingly higher requirements for ambient lighting effects, but also has a relatively low cost.

[0008] In some embodiments, a cup holder reflective sleeve is also provided on the outside of the cup holder. The inner wall of the cup holder reflective sleeve is reflective. The cup holder reflective sleeve and the cup holder together form a light guide mounting cavity adapted to the light guide. The light guide is confined in the light guide mounting cavity. The lamp head is mounted on the bottom of the cup holder reflective sleeve by a lamp head bracket. The lower end of the light guide strip extends into the lamp head after passing through the light guide mounting cavity.

[0009] In some embodiments, the bottom of the cup holder reflector is tapered to form a cylindrical connecting section with a cylindrical structure. The lamp holder bracket has a lamp holder mounting groove adapted to the lamp holder and a reflector sleeve snap-fit ​​groove adapted to the cylindrical connecting section. The lamp holder is fixedly installed in the lamp holder mounting groove. The cylindrical connecting section snaps into the reflector sleeve snap-fit ​​groove. The lower end of the light guide strip extends into the lamp holder after passing through the cylindrical connecting section.

[0010] In some embodiments, the lamp holder mounting groove is provided with a screw mounting seat, and the lamp holder housing is integrally formed with a screw connecting seat adapted to the screw mounting seat, and the screw connecting seat is locked to the screw mounting seat by a screw.

[0011] In some embodiments, the upper edge of the cup holder is integrally formed with an outwardly folded cup holder retaining ring, the outer diameter of which is greater than or equal to the outer diameter of the cup holder reflective sleeve, thereby blocking the upper edge of the light guide tube and the cup holder reflective sleeve.

[0012] In some embodiments, the optical pattern is optical teeth evenly distributed on the annular light guide section, and the cup holder is integrally molded from milky white translucent plastic.

[0013] In some embodiments, a light guide connecting sleeve adapted to the light guide strip is integrally formed on the lamp housing of the lamp head, the light guide strip is inserted into the light guide connecting sleeve, and a PCBA is installed in the lamp housing, with the light-emitting surface of an LED integrated on the PCBA facing the light-inlet end face.

[0014] In some embodiments, at least one anti-rotation protrusion and at least one positioning protrusion are integrally formed on the circumferential sidewall at the lower end of the light guide strip. Anti-rotation mating grooves that are adapted to each anti-rotation protrusion are provided on the inner wall of the light guide connecting sleeve along its axial direction. Each anti-rotation protrusion is embedded in the corresponding anti-rotation mating groove. Positioning slots that are adapted to each positioning protrusion are opened on the light guide connecting sleeve. Each positioning protrusion is snapped into the corresponding positioning slot.

[0020] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0021] like Figures 1-5 As shown, a single-source three-dimensional luminous cup holder ambient light mainly includes a cup holder 1 and an ambient light optical component.

[0022] The cup holder 1 is a cylindrical structure with an opening at the top, making it easy to place cups. Furthermore, the cup holder 1 is made of a translucent material, enabling the ambient lighting effect. In this embodiment, the cup holder 1 is integrally molded from a milky white, semi-transparent plastic, resulting in better light distribution and improved ambient lighting efficiency. Moreover, the cup holder 1 is preferably made of PC material, which is inexpensive, has high structural strength, and is durable.

[0023] The ambient lighting optical components mainly include a light guide 2 and a lamp head 3. The lamp head 3 has a conventional structure, that is, the lamp head 3 consists of a lamp housing 3a and a PCBA 3b installed in the lamp housing 3a, and an LED lamp bead 3b1 is integrated on the PCBA 3b.

[0024] The light guide 2 consists of a light guide tube 2a and a light guide strip 2b integrally formed by injection molding. In this embodiment, the light guide 2 is preferably made of transparent PC material. The light guide strip 2b has a linear structure, similar to a linear light guide. The light guide tube 2a is adapted to the cup holder 1. Specifically, the light guide tube 2a has an annular light guide section 2a1 with a cylindrical structure. The annular light guide section 2a1 is sleeved on the circumferential outer wall of the cup holder 1. The end of the annular light guide section 2a1 near the bottom of the cup holder 1 gradually narrows to form a transition section 2a2 that is integrated with the upper end of the light guide strip 2b. Furthermore, at least the circumferential outer wall of the annular light guide section 2a1 of the light guide tube 2a has optical patterns 2a11 distributed to guide light to the cup holder 1. That is, the annular light guide section 2a1 is provided with optical patterns 2a11, and the transition section 2a2 may or may not be provided with optical patterns 2a11.

[0025] In this embodiment, the optical pattern 2a11 preferably uses optical teeth that are evenly distributed on the annular light guide section 2a1, that is, the optical tooth array is distributed on the annular light guide section 2a1. Combined with the use of a milky white cup holder 1 with good light uniformity, the brightness of the cup holder 1 can be improved.

[0026] The lower end face of the light guide strip 2b is the light-inlet end face. The lamp head 3 is located at the lower end of the light guide strip 2b, and the light-emitting direction of the light source in the lamp head 3 is directly facing the light-inlet end face. Specifically, after the lower end of the light guide strip 2b is inserted into the lamp housing 3a, the light-emitting surface of the LED lamp bead 3b1 integrated on the PCBA3b is directly facing the light-inlet end face of the light guide strip 2b.

[0027] By utilizing a newly designed light guide and an overall translucent cup holder, the optical coordination between a single lamp head and the light guide can achieve a wide-area ambient lighting effect on the side wall of the cup holder, thus achieving a large-area three-dimensional luminous effect. This not only meets customers' increasingly higher requirements for ambient lighting effects, but also has a relatively low cost.

[0028] Furthermore, the transition section 2a2 is a curved structure as a whole, and both ends are connected to the annular light guide section 2a1 and the light guide strip 2b by arc transitions, thereby minimizing light scattering and increasing the brightness of the cup holder 1 when lit.

[0029] In this embodiment, a cup holder reflective sleeve 4 is also provided. The cup holder reflective sleeve 4 is located on the outside of the cup holder 1. The inner wall of the cup holder reflective sleeve 4 is reflective, thereby reflecting the light emitted from the outer wall of the light guide 2 back, thus improving the brightness of the cup holder 1. The cup holder reflective sleeve 4 can take many forms. It can be made of white PC material, which can reflect light back to the light guide 2 through diffuse reflection, and is inexpensive. The inner wall of the cup holder reflective sleeve 4 can also be coated with a reflective layer to improve the emissivity. Alternatively, the cup holder reflective sleeve 4 can be made entirely of a high-reflectivity metal material.

[0030] The cup holder reflector 4 and the cup holder 1 together form a light guide mounting cavity 5 that is compatible with the light guide 2. The light guide 2 is confined within the light guide mounting cavity 5, ensuring the reliability of the installation of the light guide 2. The lamp head 3 is mounted on the bottom of the cup holder reflector 4 via the lamp head bracket 6. The lower end of the light guide strip 2b extends from the light guide mounting cavity 5 into the lamp head 3.

[0031] In this embodiment, the bottom of the cup holder reflector sleeve 4 is tapered to form a cylindrical connecting section 4a with a cylindrical structure. The lamp holder bracket 6 has a lamp holder mounting groove 6a adapted to the lamp holder 3 and a reflector sleeve snap-fit ​​groove 6b adapted to the cylindrical connecting section 4a. The lamp holder 3 is fixedly installed in the lamp holder mounting groove 6a, the cylindrical connecting section 4a is snapped into the reflector sleeve snap-fit ​​groove 6b, and the lower end of the light guide strip 2b extends through the cylindrical connecting section 4a and into the lamp holder 3. The overall structure is simple, reliable, and easy to assemble.

[0032] The lamp holder mounting groove 6a is provided with a screw mounting seat 6a1. The lamp housing 3a of the lamp holder 3 is integrally formed with a screw connecting seat 3a2 that is compatible with the screw mounting seat 6a1. The screw connecting seat 3a2 is locked onto the screw mounting seat 6a1 by screws 7, ensuring the reliable installation of the lamp holder 3.

[0033] The lamp housing 3a of the lamp head 3 is integrally formed with a light guide connecting sleeve 3a1 that is adapted to the light guide strip 2b. The light guide strip 2b is inserted into the light guide connecting sleeve 3a1, and the LED lamp bead 3b1 is located at the inner end of the light guide connecting sleeve 3a1.

[0034] At least one anti-rotation protrusion 2b1 and at least one positioning protrusion 2b2 are integrally formed on the circumferential sidewall at the lower end of the light guide strip 2b. Anti-rotation mating grooves 3a11, each adapted to one of the anti-rotation protrusions 2b1, are provided along the axial direction of the inner wall of the light guide connecting sleeve 3a1. Each anti-rotation protrusion 2b1 is embedded in its corresponding anti-rotation mating groove 3a11. Positioning slots 3a12, each adapted to one of the positioning protrusions 2b2, are provided on the light guide connecting sleeve 3a11. Each positioning protrusion 2b2 is engaged in its corresponding positioning slot 3a12. This design not only ensures the stability and reliability of the connection between the light guide 2 and the lamp head 3, thus guaranteeing the luminous effect of the ambient light, but also provides a function to prevent assembly errors.

[0035] In this embodiment, the upper edge of the cup holder 1 is integrally formed with an outwardly folded cup holder retaining ring 1a, forming a retaining edge. Furthermore, the outer diameter of the cup holder retaining ring 1a is greater than or equal to the outer diameter of the cup holder reflective sleeve 4, thereby blocking the upper edge of the light guide tube 2a and the cup holder reflective sleeve 4. This not only avoids light leakage but also ensures the aesthetic appearance of the entire cup holder.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
