Description

Technical Field

[0001] This utility model relates to the field of automotive component technology, and in particular to a thin and waterproof illuminated welcome pedal for automobiles. Background Technology

[0002] Car door sill plates (or door sill plates) are a crucial component transitioning between the interior and exterior of a vehicle. Their function has evolved from simple protection to a vital interior element enhancing vehicle quality, brand recognition, and user experience. To further elevate the owner's sense of prestige, most door sill plates are designed to be illuminated. However, familiar car door sill plates are often limited in function, primarily made of metal or plastic, and their illuminated designs are subject to many limitations. Furthermore, known illuminated door sill plates suffer from issues such as excessive thickness (affecting aesthetics and installation compatibility), poor waterproofing (prone to short circuits from rain or car washes), and uneven illumination. These limitations make it difficult to meet diverse styling and design requirements. Utility Model Content

[0003] The purpose of this invention is to provide a thin and waterproof illuminated car door sill plate, so as to achieve the requirement of making the illuminated car door sill plate thin while having a good waterproof effect.

[0004] The thin and waterproof illuminated car door sill provided by this utility model includes the following technical means: an outer frame having a closed body with perforations around its perimeter and a plurality of bent tabs formed on the underside of the body; a light-transmitting cover having a convex surface and a concave edge surrounding the convex surface, the light-transmitting cover being assembled to the underside of the outer frame such that the convex surface is correspondingly accommodated in the perforations, the body is located on the concave edge, and the bent tabs are located around the periphery of the light-transmitting cover; and a first waterproof tape adhered to the underside of the body of the outer frame and the light-transmitting cover. The structure includes: a recessed edge; a light-diffusing paper disposed below the light-transmitting cover; a light guide plate disposed below the light-diffusing paper; a reflective paper disposed below the light guide plate; a light source electrical assembly comprising a circuit board and LEDs electrically connected to the circuit board, the light source electrical assembly being disposed below the reflective paper, and the circuit board being fixed to the light guide plate such that the LEDs align with the side of the light guide plate to project light into the light guide plate; and a second waterproof tape adhered to the underside of the light source electrical assembly; wherein a bending piece is bent to press against the underside of the second waterproof tape. With this structure, both the top and bottom of the illuminated welcome pedal achieve good sealing and waterproofing, and because the base traditionally found in similar products is omitted, the overall thickness of the illuminated welcome pedal is reduced, freeing up more space in the car for other applications.

[0005] Preferably, the present invention can be fixed between the lower two sides of the light-transmitting cover and the upper two sides of the light-diffusing paper using a first adhesive tape; the lower two sides of the light-diffusing paper and the upper two sides of the light guide plate using a second adhesive tape; and the lower two sides of the light guide plate and the upper two sides of the reflective paper using a third adhesive tape. This avoids increasing the thickness due to the use of mechanical fixing components.

[0006] Preferably, the present invention includes two circuit boards disposed on opposite sides of the light source electrical assembly, each circuit board having an LED. These LEDs project light from opposite ends of the light guide plate and conduct it within the light guide plate. Accordingly, a longer illuminated welcome tread can achieve a uniform illumination effect without increasing its thickness.

[0007] Preferably, through holes can be provided on opposite sides of the light guide plate, and the LEDs are located within these through holes. The light emitted by the LEDs is projected into the light guide plate from the side of the through holes and conducted. Accordingly, the thickness of the entire illuminated welcome pedal can be reduced because the LEDs are housed within the through holes.

[0008] Compared with the prior art, the beneficial effects of this utility model are: this utility model is provided with an outer frame, a light-transmitting cover, a first waterproof tape, a light-diffusing paper, a light guide plate, a reflective paper, a light source electrical assembly, a second waterproof tape and other structures, which can realize the thinning of the car's illuminated welcome pedal, while also having a good waterproof effect.

Detailed Implementation

[0011] To facilitate understanding of this utility model, it will be described in detail below with reference to the accompanying drawings and embodiments. The drawings show some, but not all, embodiments of this utility model. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to enable those skilled in the art to gain a more thorough and comprehensive understanding of the contents of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without inventive changes are within the scope of protection of this utility model.

[0012] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0013] like Figures 1 to 4 As shown, the thin and waterproof car illuminated welcome pedal provided by this utility model includes: an outer frame 10, a first waterproof tape 20, a light-transmitting cover 30, a light-diffusing paper 50, a light guide plate 70, a reflective paper 90, a light source electrical assembly 100, and a second waterproof tape 110. The outer frame 10 serves as a protective frame for the illuminated welcome pedal and can be made of steel plate by stamping into a body 101 with a closed perimeter. Figure 1 The outer frame 10 is a rectangular frame. Holes are formed between the area enclosed by the body 101, and a plurality of bent pieces 102 are formed on the bottom of the body 101, such that the bent pieces 102 are distributed and arranged around the body 101.

[0014] The light-transmitting cover 30 has a convex surface 301 and a concave edge 302 surrounding the convex surface 301, that is, a step is formed between the convex surface 301 and the concave edge 302. The light-transmitting cover 30 can be manufactured using spray painting combined with laser engraving technology, that is, an opaque black paint is sprayed on the inner surface of the light-transmitting cover 30, and then the pattern or text that needs to be translucent is engraved on the black paint by laser engraving. The light-transmitting cover 30 is used to be assembled under the outer frame 10, so that the convex surface 301 is correspondingly accommodated in the hollow hole of the outer frame 10, while the body 101 is located on the concave edge 302, and the bent pieces 102 are arranged around the periphery of the light-transmitting cover 30. The light-transmitting cover 30 and the outer frame 10 are combined by attaching one side of the first waterproof tape 20 to the concave edge 302 of the light-transmitting cover 30, and the other side of the first waterproof tape 20 to the underside of the body 101 of the outer frame 10. The first waterproof tape 20 forms a seal between the periphery of the outer frame 10 and the light-transmitting cover 30 to prevent water seepage.

[0015] The light-diffusing paper 50 is a component used to generate a light-mixing effect. It can be a light-mixing film made of, for example, PET material, but is not limited to PET. The light-diffusing paper 50 can perform secondary light mixing processing, making the light distribution more uniform, avoiding uneven light spots, and improving the comfort of the lighting effect. The light-diffusing paper 50 is located below the light-transmitting cover 30, and is fixed between the lower two sides of the light-transmitting cover 30 and the upper two sides of the light-diffusing paper 50 by a first adhesive tape 40.

[0016] The light guide plate 70 is a component used to transmit light, also known as a "light guide". Its lower surface has reflective dots 702. The design of the reflective dots 702 reflects the light transmitted through the light guide plate 70, making the light emission from the light-emitting surface of the light guide plate 70 more uniform. The light guide plate 70 is disposed below the light-diffusing paper 50, and is fixed between the lower two sides of the light-diffusing paper 50 and the upper two sides of the light guide plate 70 using a second adhesive tape 60. Furthermore, through holes 701 can be provided on opposite sides of the light guide plate 70. To improve the reflectivity of the light guide plate 70, reflective paper 90 is also disposed below the light guide plate 70, and is fixed between the lower two sides of the light guide plate 70 and the upper two sides of the reflective paper 90 using a third adhesive tape 80.

[0017] The light source electrical assembly 100 is an electrical device used to provide a light source. It includes a circuit board 1001 and LEDs 1002 electrically connected to the circuit board 1001. In this embodiment, two circuit boards 1001 are included, each with a plurality of LEDs 1002. The two circuit boards 1001 are electrically connected by a power line, which connects to electrical components such as a transformer. The LEDs 1002 are controlled by a circuit to emit light. The light source electrical assembly 100 is located below the reflective paper 90 and can be fixed to the light guide plate 70 by thermal riveting. After fixing, the LEDs 1002 on the two circuit boards 1001 are respectively accommodated in the through holes 701 of the light guide plate 70, so that the optical axis of the LEDs 1002 corresponds to the side of the through hole 701, that is, the light generated by the LEDs 1002 is projected into the light guide plate 70 from the side of the through hole 701 and conducted.

[0018] The second waterproof tape 110 is a relatively large waterproof tape. After the light guide plate 70 and the light source electrical assembly 100 are fixed together, the second waterproof tape 110 is attached to the underside of the light source electrical assembly 100 to completely cover and shield the circuit board 1001 and some power lines. Finally, the bending piece 102 of the outer frame 10 is bent to press against the underside of the second waterproof tape 110 for auxiliary fixation.

[0019] When the aforementioned LED 1002 is controlled to emit light, the LED 1002 located in the through hole 701 of the light guide plate 70 projects light into the light guide plate 70 for conduction. The light is then reflected by the dot structure 702 and the reflective paper 90, and then the light is homogenized by the light-diffusing paper 50 before emitting light through the light-transmitting cover 30.

[0020] The aforementioned illuminated welcome pedal structure for automobiles has the following advantages: 1. The components are fixed together with adhesive tape, without the use of mechanical fixing components. This allows the overall luminous pedal to be thinner, providing more possibilities for designing luminous pedals in confined spaces.

[0021] 2. The light-transmitting cover 30 uses spray painting combined with laser engraving technology to form patterns or text, which can meet the needs of various complex shapes.

[0022] 3. The bottom is completely covered with a second waterproof tape 110, which meets certain waterproof requirements.

[0023] 4. Improved assembly process, such as the use of thermal riveting between the circuit board and the light guide plate, which makes the fixed positioning more stable, ensures the stability of light emission, and extends the life of the light-emitting pedal.

[0024] In summary, the luminous welcome pedal of this utility model uses LEDs to project light into the light guide plate in a side-emitting manner. Furthermore, the various parts are bonded together with adhesive tape and sealed with waterproof tape. This eliminates the need for extensive assembly structures and successfully enables the creation of various luminous patterns in limited spaces with certain waterproof requirements (such as car door sills).

[0025] The embodiments described above are merely preferred embodiments of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various changes and modifications without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
