Description

Technical Field

[0001] This utility model belongs to the field of horn technology, specifically referring to a car horn with a light warning function. Background Technology

[0002] Car horns are crucial active safety devices in vehicles, and their acoustic warning function is of paramount importance. With the trends towards intelligent and personalized automobiles, integrating lighting functions to enhance the interactive experience and visual appeal has become an important development direction for car horns.

[0003] In existing technologies, such as the "car horn with a semi-transparent paper cone" disclosed in Chinese patent CN217985317U, the light-emitting area is successfully expanded from the traditional outer ring to the entire vibrating surface by using a semi-transparent paper cone and designing a light-transmitting pattern, achieving significant progress in increasing the light-emitting area and pattern diversity. However, its lamp board is mainly attached to the frame and rear cover with screws, lacking effective shock absorption and efficient heat dissipation path design. Under the continuous high-frequency vibration and temperature change conditions of the car horn, this fixing method is prone to screw loosening, lamp board deformation, and even poor soldering of the LED beads, causing the light to flicker or not light up; at the same time, heat accumulation will accelerate LED light decay and shorten its service life. Therefore, how to optimize the fixing and heat dissipation structure of the lamp board to ensure the long-term stability of the acoustic and optical performance is a key problem that has not yet been properly solved by existing technologies. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a car horn with a lighting warning function. The technical problem this invention aims to solve is how to optimize the fixing and heat dissipation structure of the light panel to ensure long-term stability of its acoustic and visual performance.

[0005] The objective of this utility model can be achieved through the following technical solution: A car horn with a light warning function includes a horn frame, in which a paper cone is fixedly installed, and a magnet is installed at its bottom. A first light-emitting element is fixedly connected to the middle of the horn frame, and the wire of the first light-emitting element passes through the magnet and extends outward. A shell is assembled on the top of the horn frame, and the shell has multiple light-transmitting and heat-dissipating holes. The inner wall of the shell is integrally formed with positioning posts and fixing holes. The horn frame is provided with several adjustment holes. During assembly, the positioning posts are inserted into the adjustment holes to achieve pre-positioning, and the shell and the horn frame are firmly connected by fixing parts passing through the adjustment holes and fixing holes. The light-transmitting and heat-dissipating holes are arranged opposite to the first light-emitting element. The raised structure of the positioning posts and fixing holes provides a larger space between the shell and the first light-emitting element, allowing for better heat dissipation and better positioning and fixing of the horn frame and the shell.

[0006] Furthermore, the speaker frame includes an annular flat plate fixing part, and the adjustment holes are evenly distributed circumferentially on the flat plate fixing part; the outer periphery of the flat plate fixing part extends towards the outer shell to form a positioning flange; the positioning post includes a first cylinder and a second cylinder coaxially arranged, and the diameter of the second cylinder is smaller than that of the first cylinder; after assembly, the surface of the flat plate fixing part abuts against the end face of the first cylinder, the inner surface of the positioning flange fits against the outer peripheral surface of the first cylinder, and the second cylinder passes through the adjustment hole. This solution enables precise pre-positioning and multiple limiting between the outer shell and the speaker frame.

[0007] Furthermore, a mounting hole is provided in the middle of the outer shell, and a light-transmitting element is fixedly installed in the mounting hole; the light-transmitting element has multiple refractive microstructures for diffuse reflection of light inside.

[0008] Furthermore, the outer shell is integrally formed from a light-transmitting heat dissipation part, a cylindrical fixing part, and a circular part that radially protrudes from the outer periphery of the cylindrical fixing part; the light-transmitting heat dissipation hole is provided on the light-transmitting heat dissipation part; and the positioning post and fixing hole are provided on the inner surface of the light-transmitting heat dissipation part.

[0009] Furthermore, a second light-emitting element is fixedly connected to the outer periphery of the cylindrical fixing part, and a protective cover is fixedly connected to the outside of the cylindrical fixing part by a buckle, the protective cover covering the second light-emitting element.

[0010] Furthermore, the annular portion is provided with at least two through holes, which are arranged opposite to the second light-emitting element.

[0011] Compared with existing technologies, the technical effects of this utility model are as follows: 1. By integrally forming a positioning post on the inner wall of the outer shell and setting matching adjustment holes and positioning flanges on the speaker frame, precise pre-positioning and multiple limiting between the outer shell and the speaker frame are achieved. This stepped positioning fit combined with fastener locking significantly enhances the rigidity and stability of the overall assembly, effectively resisting continuous vibration during vehicle operation and preventing displacement, poor welding, or failure of the light panel due to loosening, thereby ensuring the long-term stable operation of the audible and visual warning function. 2. Multiple light-transmitting and heat-dissipating holes on the outer shell face the first light-emitting element, forming a direct and efficient air convection heat dissipation channel, which can quickly dissipate the heat generated by the first light-emitting element during operation to the external environment. This active heat dissipation design avoids the accumulation of heat in the confined space, effectively slowing down the light decay process of the first light-emitting element and extending its service life. 3. By setting a central light-transmitting element with internal refractive microstructures and adding a second light-emitting element to the outer cylindrical fixing part and protecting it with a protective cover with through holes, a multi-level lighting system of a central surface light source plus an outer ring light source is constructed. The refractive structure of the central light-transmitting element causes diffuse reflection of light, creating a soft and uniform surface-emitting effect that avoids glaring spots; the outer secondary light-emitting element expands the warning range. This three-dimensional, layered lighting effect not only has a stronger visual impact and a more technological aesthetic, but also provides more conspicuous visual warnings in complex lighting environments, further enhancing driving safety.

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] It should be noted that the descriptions of "up", "down", "left", "right", "top", "bottom", etc. in this utility model are defined based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device must be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] like Figures 1 to 5 As shown, the present invention provides a car horn with a light warning function, which mainly includes a horn frame 1, a paper cone 2, a magnet 3, a first light-emitting element 4, a shell 5, and a light-transmitting element 6.

[0021] The speaker frame 1 serves as the core support structure, with a paper cone 2 for sound generation fixedly mounted on its inner ring and a magnet 3 fixedly installed at its bottom. A first light-emitting element 4, preferably an LED light, is fixedly connected to the middle of the speaker frame 1. The connecting wire 9 of the first light-emitting element 4 passes through a pre-drilled hole in the center of the magnet 3 and extends outward to connect to the vehicle's power supply and control circuit.

[0022] The top of the speaker frame 1 is fitted with a housing 5. In this embodiment, the housing 5 is preferably integrally molded from light-transmitting plastic or polycarbonate material by injection molding, and its structure can be divided into three main parts: a light-transmitting heat dissipation part 51 located at the top, a cylindrical fixing part 52 connected to the light-transmitting heat dissipation part 51 and extending downward, and a circular ring part 53 protruding radially outward from the outer periphery of the cylindrical fixing part 52.

[0023] On the light-transmitting and heat-dissipating part 51, there are multiple light-transmitting and heat-dissipating holes 511 that combine light transmission and heat dissipation functions. These light-transmitting and heat-dissipating holes 511 can be in various shapes such as circular, triangular, square, grid-shaped, or rectangular, and are evenly arranged around the first light-emitting element 4, ensuring that they are vertically aligned with the first light-emitting element 4. This design allows the light generated by the first light-emitting element 4 to be emitted smoothly, while the heat generated during its operation can be quickly carried away by convection with the outside air through the light-transmitting and heat-dissipating holes 511, thereby creating an efficient active heat dissipation channel.

[0024] The key feature is that two positioning posts 512 and two fixing holes 513 are integrally formed on the inner surface of the light-transmitting and heat-dissipating part 51. The positioning posts 512 adopt a stepped shaft structure, including a first cylinder 5121 with a larger diameter and a second cylinder 5122 with a smaller diameter, which are coaxially arranged.

[0025] Correspondingly, the speaker frame 1 includes an annular flat plate fixing part 11. On this flat plate fixing part 11, adjustment holes 111 are evenly distributed circumferentially, matching the number and position of the positioning posts 512. The outer periphery of the flat plate fixing part 11 also extends towards the outer casing 5 to form a positioning flange 112.

[0026] During assembly, first align the outer casing 5 with the speaker frame 1, allowing the second cylinder 5122 of the positioning post 512 to pass through the adjustment hole 111 on the speaker frame 1, achieving initial radial pre-positioning. As the outer casing 5 continues to press down, the upper surface of the flat plate fixing part 11 will abut against the outer end face of the first cylinder 5121 of the positioning post 512, while simultaneously, the inner circumferential surface of the positioning flange 112 will fit against the outer circumferential surface of the first cylinder 5121. This combination of end face abutment and circumferential surface fit creates multiple limiting mechanisms, greatly enhancing the stability and torsional resistance of the assembly. Finally, screws or other fasteners are used to sequentially pass through the adjustment hole 111 and the fixing hole 513 on the outer casing 5 and lock them in place, thereby firmly and securely connecting the outer casing 5 and the speaker frame 1 together. Of particular importance is that, since the positioning post 512 and the fixing hole 513 are raised structures formed by protrusions from the inner surface of the outer shell 5, an ample heat dissipation space is formed between the inner cavity of the outer shell 5 and the first light-emitting element 4. This not only facilitates airflow and enhances the heat dissipation effect, but also ensures that the light from the first light-emitting element 4 can be emitted without obstruction.

[0027] Furthermore, a mounting hole is provided in the middle of the light-transmitting and heat-dissipating part 51 of the outer shell 5, and a light-transmitting element 6 is fixedly installed in the mounting hole by interference fit or adhesive. The interior of the light-transmitting element 6 is designed with multiple refractive microstructures, which enable the direct light emitted by the first light-emitting element 4 to undergo diffuse reflection, thereby forming a soft and uniform surface light emission effect, avoiding the generation of glaring light spots and enhancing the visual aesthetics.

[0028] To create a more three-dimensional lighting warning effect, a second light-emitting element 7, preferably an LED light strip, can be fixedly connected to the outer peripheral wall of the cylindrical fixing part 52 of the outer casing 5 via a slot or screw. A protective cover 8 is fixedly connected to the outside of the second light-emitting element 7 by a snap-fit ​​method. This protective cover 8 serves to prevent dust, water, and provide physical protection. Correspondingly, at least two through holes 531 are provided on the annular part 53, opposite to the position of the second light-emitting element 7.

[0029] The specific embodiments described herein are merely illustrative of the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
