Description

Technical Field

[0001] This utility model belongs to the field of traffic facility technology, and in particular relates to an acoustic and optical traffic cone. Background Technology

[0002] Sound and light traffic cones are intelligent traffic safety devices that combine the physical warning function of traditional traffic cones with sound and light prompts. They are mainly used in scenarios such as road construction, accident scenes, and temporary traffic control to enhance the warning effect at night or in low visibility environments.

[0003] The disclosed acoustic-optical road cones in related technologies still have some shortcomings. Traditional loudspeakers are large and heavy. In order to stabilize the overall center of gravity of the acoustic-optical road cone, the loudspeaker is installed in the bottom cavity of the cone. However, this arrangement causes the sound transmitted by the loudspeaker to be affected by the ground absorption, shortening the propagation distance. If the loudspeaker is moved upwards directly inside the cavity of the acoustic-optical road cone, it is easy to cause the center of gravity of the cone to be unstable, affecting the stability of use. Utility Model Content

[0004] To overcome the problems existing in related technologies, this application provides an acoustic-optical road cone.

[0005] This utility model provides a sound and light road cone, including a conical shell, on which a power supply device, a horn and a warning light are installed. The power supply device is installed in the bottom cavity of the conical shell, and the horn is installed in the middle cavity of the conical shell. The horn is a strong magnetic horn.

[0006] In some embodiments, a counterweight stabilizing block mounting position is also preset in the bottom cavity of the conical shell.

[0007] In some embodiments, the conical housing is fitted with a sound cavity cover, and the main body of the speaker is disposed within the sound cavity cover.

[0008] In some embodiments, the tail end of the horn is connected to the lower end of the horn mounting bracket, the upper end of the horn mounting bracket is fixedly connected to the conical housing, and a reinforcing pad is provided on the conical housing at the position where it connects to the horn mounting bracket.

[0009] In some embodiments, a centralized control module and a radar sensing module are also installed on the conical housing, with the radar sensing module installed in the upper recess of the conical housing.

[0010] In some embodiments, the horn, the warning light, and the radar sensing module are located on the same side of the conical housing.

[0011] In some embodiments, the centralized control module and the horn are located on opposite sides of the conical housing.

[0012] In some embodiments, the conical housing is a one-piece molded housing, and the conical housing is provided with a power supply device mounting port, a horn mounting port, a centralized control module mounting port, and a radar sensing module mounting port. The power supply device is installed into the bottom cavity of the conical housing through the power supply device mounting port, the horn is installed into the middle cavity of the conical housing through the horn mounting port, the centralized control module is installed into the conical housing through the centralized control module mounting port, and the radar sensing module is installed into the upper recess of the conical housing through the radar sensing module mounting port.

[0013] In some embodiments, the conical shell is manufactured using a blow molding process.

[0014] In some embodiments, the centralized control module includes a sealing cover, a control panel, and a fastener, the control panel being connected to the middle of the fastener, the sealing cover being threadedly located on the outer side of the middle of the fastener, and the fastener being circumferentially sealed to the mounting port of the centralized control module.

[0015] The sound and light traffic cone provided by this utility model has two advantages. First, the horn position is moved upwards compared to the horn position in traditional sound and light traffic cones. The horn is no longer located at the bottom of the conical shell, reducing interference from the ground and increasing the sound propagation distance and decibel level, thereby enhancing the penetration effect through vehicle windows and improving warning effectiveness. Second, the horn uses a strong magnetic horn, which is small in size and lightweight, solving the problem of instability caused by the upward movement of the horn in traditional models. Therefore, the sound and light traffic cone provided by this utility model has the advantages of both good horn warning effect and good operational stability. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please refer to Figures 1 to 4 , Figure 1 A three-dimensional structural schematic diagram of the acoustic-optical road cone provided in a specific embodiment of this utility model; Figure 2 This is a schematic diagram of the right cross-sectional structure of an acoustic-optical road cone provided in a specific embodiment of the present invention. Figure 3 This is a schematic diagram of the main structure provided for a specific embodiment of the present utility model; Figure 4 This is a schematic diagram showing the relative positions of the horn, warning light, centralized control module, and radar sensing module in a sound and light road cone according to a specific embodiment of this utility model.

[0025] This utility model provides a sound and light road cone comprising a conical shell 1, on which a power supply device (not shown in the figure), a horn 2, and LED warning lights 3 are mounted. The LED warning lights 3 are evenly distributed along the upper periphery of the conical shell 1, and normally flash normally to oncoming vehicles. The power supply device is installed in the bottom cavity of the conical shell 1, and can be a battery. The horn 2 is installed in the middle cavity of the conical shell 1. The horn 2 is a high-magnetic horn, which has higher electroacoustic conversion efficiency and greatly improves product stability. The horn 2 can be arranged along the upper periphery of the conical shell 1, with at least one horn, and can be activated for sound warning under specific circumstances.

[0026] In the sound and light traffic cone provided in this embodiment of the invention, on the one hand, the position of the horn 2 is moved upwards compared to the horn position in traditional sound and light traffic cones. The horn 2 is no longer located at the bottom of the conical housing 1, which reduces interference from the ground on the sound propagation of the horn 2, increases the sound propagation distance and decibel level, thereby enhancing the penetration effect through vehicle windows and improving the warning effectiveness. On the other hand, the horn 2 uses a strong magnetic horn, which is small in size and light in weight, solving the problem of instability caused by the upward movement of the horn in traditional designs. Therefore, the sound and light traffic cone provided in this embodiment of the invention has the advantages of both good horn warning effect and good operational stability.

[0027] Preferably, the circuit design of the strong magnetic speaker includes a power amplifier circuit to increase the speaker's output power to increase the decibel level and enhance sound penetration.

[0028] Based on the above embodiments, a counterweight stabilizing block mounting position is also pre-set in the bottom cavity of the conical shell 1. By pre-setting a counterweight stabilizing block mounting position in the bottom space of the conical shell 1, counterweights can be added as needed, lowering the overall center of gravity of the product and further enhancing the stability of the acoustic-optical road cone in this embodiment, as well as increasing its wind resistance.

[0029] In some embodiments, a sound cavity cover 4 is inlaid inside the conical housing 1, and the main body of the horn 2 is disposed inside the sound cavity cover 4. This arrangement allows the strong magnetic horn to be adapted to the sound cavity inside the sound cavity cover 4. The sound cavity cover 4 provides a directional sound cavity for the strong magnetic horn, optimizing sound propagation. The strong magnetic horn has high electroacoustic conversion efficiency, thereby further enhancing the penetration effect through the vehicle window and thus further improving the warning effectiveness of the horn. The sound cavity cover 4 is manufactured using injection molding, which improves the standardization of the sound cavity.

[0030] Based on the above embodiment, the tail of the speaker 2 is connected to the lower end of the speaker mounting bracket 21, and the upper end of the speaker mounting bracket 21 is fixedly connected to the conical housing 1. A reinforcing pad 11 is provided at the connection point between the conical housing 1 and the speaker mounting bracket 21. This improves the strength of the connection point between the conical housing 1 and the speaker mounting bracket 21, making the connection between the speaker mounting bracket 21 and the conical housing 1 more secure and increasing the product's service life. Simultaneously, the speaker 2 can be supported by the sound chamber cover 4 and the speaker mounting bracket 21 respectively, providing stable support for heavier, stronger magnetic speakers.

[0031] In some embodiments, a centralized control module 5 and a radar sensing module 6 are also installed on the conical housing 1, with the radar sensing module 6 installed in the upper recess of the conical housing 1. A power supply device is electrically connected to each of the horn 2, warning light 3, and centralized control module 5, specifically via a wire. The centralized control module 5 is electrically connected to the horn 2, warning light 3, and radar sensing module 6. In this embodiment, the centralized control module 5 is connected to the horn 2 and warning light 3 via wires, and the centralized control module 5 is wirelessly connected to the radar sensing module 6. The centralized control module 5 facilitates control of the operating modes of the warning light 3 and the horn 2.

[0032] The radar sensing module 6 is installed on the upper part of the conical housing 1, which facilitates vehicle identification. The radar sensing module 6 can identify the left-hand fast lane, driving lane, and emergency lane. Under normal conditions, the LED warning light 3 flashes normally at oncoming vehicles. When the radar sensing module 6 detects an oncoming vehicle approaching in the warning lane, it triggers the strong magnetic horn to activate an audible warning until the vehicle changes lanes and there are no vehicles in the warning area, at which point the audible warning stops. Therefore, the radar sensing module 6 in this embodiment can achieve lane-specific warnings, accurately detect and trigger warnings for different lanes, reduce unnecessary sound interference, and improve the targeting and intelligence of the warnings.

[0033] In some embodiments, the horn 2, warning light 3, and radar sensing module 6 are located on the same side of the conical housing 1, which facilitates warning and identification of oncoming vehicles.

[0034] Based on the above embodiment, the centralized control module 5 and the horn 2 are installed on opposite sides of the conical housing 1. Placing the centralized control module 5 on the opposite side of the horn 2 allows it to avoid occupying the area of ​​the side of the conical housing 1 facing the vehicle, maximizing the number of functional modules. Furthermore, the opposite arrangement of the horn 2 and the centralized control module 5 also contributes to the overall balance of the product.

[0035] In some embodiments, the conical housing 1 is an integrally formed housing, and the conical housing 1 is provided with a power supply device mounting port 71, a horn mounting port 72, a centralized control module mounting port 73, and a radar sensing module mounting port 74. The power supply device is installed into the bottom cavity of the conical housing 1 through the power supply device mounting port 71, the horn 2 is installed into the middle cavity of the conical housing 1 through the horn mounting port 72, the centralized control module 5 is installed into the conical housing 1 through the centralized control module mounting port 73, and the radar sensing module 6 is installed into the upper recess of the conical housing 1 through the radar sensing module mounting port 74.

[0036] In this embodiment, the conical shell 1 is a one-piece molded structure, which significantly improves waterproof performance and extends the service life of the equipment compared to a split structure. It is equipped with a power supply mounting port 71, a horn mounting port 72, a centralized control module mounting port 73, and a radar sensing module mounting port 74, facilitating the installation of each functional module into the cavity of the conical shell 1 through these mounting ports.

[0037] In this embodiment, the central control module mounting port 73 is located above the opposite side of the speaker mounting port 72, which facilitates the installation of the tail of the speaker 2 and the speaker mounting bracket 21 through the central control module mounting port 73.

[0038] In some embodiments, the conical shell 1 is manufactured using a blow molding process. Compared to injection molding, blow molding reduces mold costs, and compared to rotational molding, it improves production efficiency, significantly optimizing overall manufacturing costs.

[0039] In some embodiments, the centralized control module 5 includes a sealing cover 51, a control panel 52, and a fixing member 53. The control panel 52 is connected to the middle of the fixing member 53, and the sealing cover 51 is threaded to the outer side of the middle of the fixing member 53. The fixing member 53 is circumferentially sealed to the mounting port 73 of the centralized control module. It is understood that the control panel 52 is also connected to the control motherboard. Sealing structures are also provided at the power supply mounting port 71 and the speaker mounting port 72, which can seal the mounting ports after the power supply device and speaker 2 are installed. The fixing member 53 can be made of injection molded material and can be fixed to the conical housing 1 with bolts using a sealing strip. This increases the overall waterproofness of the product.

[0040] In summary, when used in this application, the above-mentioned structure and design achieve more accurate, intelligent, and stable traffic warnings, while balancing cost and performance.
