Description

Technical Field

[0001] This utility model relates to the field of electronic product technology, and in particular to a projector. Background Technology

[0002] In today's electronics market, projectors, speakers, and other devices not only pursue superior performance, but their appearance design is also receiving increasing attention, becoming one of the important factors in attracting consumers. Currently, the means of decorating the appearance of these electronic products are relatively limited, mostly using static materials and textures, or adding LED light strips.

[0003] To enhance visual appeal, some high-end products incorporate colored LED light strips on the front panel or around the lens. This design serves a decorative purpose, enriching the product's attributes beyond its functionality and allowing customers to perceive greater product value. For instance, colored LED light strips can create a unique ambiance, enhancing the user experience.

[0004] However, this common decorative solution has significant shortcomings. Firstly, it requires additional LED chips, circuit boards, controllers, and power supplies, increasing hardware costs and complicating product structure, posing challenges to production and assembly. Secondly, if the color and effects of the LED strips are fixed and cannot be synchronized with the projected content in real time, the decorative effect will appear monotonous and lack dynamic variation, failing to meet the increasingly diverse aesthetic needs of users. Furthermore, the additional electronic components increase power consumption and introduce more potential points of failure, affecting product stability and reliability.

[0005] Therefore, there is an urgent need for a projector to solve the aforementioned problems. Utility Model Content

[0006] Based on the above, the purpose of this utility model is to provide a projector in which the color and brightness of the light-emitting surface are directly derived from the projected image, and can follow the changes in the image content in real time, ultimately forming a uniform and bright colored light band at the edge; achieving a truly "zero-cost" enhancement of decorative effect and improving product reliability; the decorative panel itself is part of the appearance surface, with a strong sense of unity, and will not destroy the integrated design aesthetics of the product.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A projector, comprising:

[0009] A housing assembly having a cavity, the housing assembly including a transparent decorative panel disposed on one side of the housing assembly, the decorative panel having a receiving hole extending toward one side of the cavity;

[0010] A projection lens module is installed in the cavity, and the light-emitting part of the projection lens module is located in the end of the receiving hole near the cavity. The inner wall of the receiving hole forms a light-incident surface, and the edge of the decorative panel forms a light-emitting surface. The light-incident surface can receive the light emitted by the light-emitting part.

[0011] As a preferred technical solution for a projector, the end face of the receiving hole away from the cavity is transitioned to the inner wall of the receiving hole by a rounded corner.

[0012] As a preferred technical solution for a projector, the projection lens module is fitted with the receiving hole with a clearance.

[0013] As a preferred technical solution for a projector, the light-incident surface is uniformly provided with multiple protrusions.

[0014] As a preferred technical solution for a projector, the raised surface is arc-shaped or prismatic.

[0015] As a preferred technical solution for a projector, the light-emitting surface is a frosted surface.

[0016] As a preferred technical solution for a projector, the light-emitting surface is serrated.

[0017] As a preferred technical solution for a projector, the distance between the end face of the receiving hole away from the cavity and the end face of the light-emitting part is 12mm-20mm.

[0018] As a preferred technical solution for a projector, the housing assembly further includes a housing body and a connecting frame. An opening is provided on one side of the housing body, the connecting frame is connected to the opening, and the decorative panel is snapped into the connecting frame.

[0019] As a preferred technical solution for a projector, the decorative panel is an acrylic panel or a polycarbonate panel.

[0020] The beneficial effects of this utility model are as follows:

[0021] This invention provides a projector in which the light-emitting part of the projection lens module emits light during operation. The inner wall of the receiving hole forms a light-incident surface, which receives large-angle light rays emitted from the light-emitting part of the projection lens module in various directions. The optical fiber then undergoes continuous total internal reflection between the front and rear surfaces of the decorative panel, achieving long-distance light transmission. The edge of the decorative panel forms a light-emitting surface, which breaks the total internal reflection condition, allowing the light to escape. Firstly, this invention achieves a complete "capture-conduction-emission" light path within the decorative panel. The color and brightness of the light-emitting surface directly originate from the projected image, allowing it to change in real-time with the image content, ultimately forming a uniform and bright colored light band at the edge, resulting in a vivid and immersive decorative effect. Secondly, this projector completely eliminates the need for traditional LED light strips, driver circuits, and related control modules, achieving true "zero-cost" decoration. It requires no additional electronic components, reducing potential failure points and improving product reliability. Furthermore, its structure is easily integrated into existing projector housing designs. Thirdly, the decorative panel itself is part of the overall appearance, creating a strong sense of unity and preserving the product's aesthetic design. Attached Figure Description

[0031] Currently, there are significant shortcomings in using colored LED light strips to create unique atmospheres. Firstly, they require additional LED chips, circuit boards, controllers, and power supplies, increasing hardware costs and complicating product structure, posing challenges to production and assembly. Secondly, if the colors and effects of the LED light strips are fixed and cannot be synchronized with the projected content in real time, the decorative effect will appear monotonous and lack dynamic variation, failing to meet the increasingly diverse aesthetic needs of users. Furthermore, the additional electronic components increase power consumption and introduce more potential points of failure, affecting product stability and reliability.

[0032] To solve the above problems, such as Figure 1 and Figure 2As shown, this embodiment provides a projector, which includes a housing assembly 1 and a projection lens module 2. The housing assembly 1 is provided with a cavity and includes a transparent decorative panel 11. The decorative panel 11 is disposed on one side of the housing assembly 1 and has a receiving hole 111 extending toward one side of the cavity. The projection lens module 2 is installed in the cavity, and the light-emitting part of the projection lens module 2 is located in the receiving hole 111 at one end near the cavity. The inner wall of the receiving hole 111 forms a light-incident surface 112, and the edge of the decorative panel 11 forms a light-emitting surface 113. The light-incident surface 112 can receive the light emitted by the light-emitting part.

[0033] When the projector is working, the light-emitting part of the projection lens module 2 emits light. At this time, the inner wall of the receiving hole 111 forms a light-incident surface 112. The light-incident surface 112 receives large-angle light rays emitted from the light-emitting part of the projection lens module 2 in various directions. Then, the optical fiber undergoes total internal reflection between the front and rear surfaces of the decorative panel 11, thereby achieving long-distance light transmission. The edge of the decorative panel 11 forms a light-emitting surface 113, which is used to break the total internal reflection condition and allow the light to be emitted. Firstly, a complete light path of "capture-transmission-emission" is realized within the decorative panel 11. The color and brightness of the light-emitting surface 113 are directly derived from the projected image and can follow the changes in the image content in real time, ultimately forming a uniform and bright colored light band at the edge, resulting in a vivid and immersive decorative effect. Secondly, this projector completely eliminates the need for traditional LED light strips, drive circuits, and related control modules, achieving a truly "zero-cost" addition of decorative effects. It requires no additional electronic components, reduces potential failure points, improves product reliability, and its structure is easy to integrate into existing projector housing designs. Thirdly, the decorative panel 11 is part of the exterior surface, giving it a strong sense of unity and not compromising the product's integrated design aesthetics.

[0034] Preferably, the end face of the receiving hole 111 away from the cavity transitions to the inner wall of the receiving hole 111 through a fillet 114. This makes the light-receiving surface 112 as smooth and transparent as possible to improve light transmittance and better capture large-angle light from the lens.

[0035] In this embodiment, the projection lens module 2 is fitted with the receiving hole 111 with a clearance. On the one hand, this facilitates the projection lens module 2 to extend into the receiving hole 111; on the other hand, there is a clearance between the receiving hole 111 and the projection lens module 2 so that the receiving hole 111 does not affect the extension and retraction of the projection lens module 2 when it is focusing.

[0036] In this embodiment, the light-incident surface 112 is uniformly provided with multiple protrusions. The multiple protrusions form a microstructure array, which can receive more light. Among them, the surface of the protrusions is arc-shaped or prismatic.

[0037] Preferably, the light-emitting surface 113 is a frosted surface, and the light-emitting surface 113 is treated with a frosting process to disperse the light, such as by creating a textured surface, microstructure, or frosted texture, thereby improving the uniformity of light emission from the light-emitting surface 113. In other embodiments, the light-emitting surface 113 is serrated.

[0038] In this embodiment, the distance between the end face of the receiving hole 111 away from the cavity and the end face of the light-emitting part is 12mm-20mm, ensuring that the area of ​​the light-receiving surface 112 receiving light is large enough so that the light-receiving surface 112 on the inner wall of the receiving hole 111 can receive large-angle light emitted from all directions of the light-emitting part.

[0039] The housing assembly 1 also includes a housing body 12 and a connecting frame 13. An opening is provided on one side of the housing body 12, and the connecting frame 13 is connected to the opening. The decorative panel 11 is snapped into the connecting frame 13, thus fixing the decorative panel 11. In this embodiment, the light-emitting surface 113 of the decorative panel 11 faces the connecting frame 13. When the projector is working, the edge of the decorative panel 11 can generate a colored light strip. The user can observe the colored light strip illuminating the connecting frame 13 through the transparent decorative panel 11, enhancing the decorative effect.

[0040] In this embodiment, the decorative panel 11 is an acrylic sheet or a polycarbonate sheet. The decorative panel 11 can also be optical glass, and its shape is adapted to the front appearance of the projector. It can be a flat panel, a curved mask, or other decorative shapes.

[0041] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
