Description

Technical Field

[0001] The present invention belongs to the technical field of speaker triggering structures, and in particular relates to a two-stage speaker triggering structure. Background Art

[0002] With the rapid development of the automobile industry, cars have become an indispensable means of transportation in modern society, greatly facilitating people's travel. However, with the surge in the number of cars, urban traffic problems have become increasingly prominent, among which the use of car horns is particularly prominent. The design of traditional car horns is simple and direct, using a press-and-sound method, triggering the horn to sound through the contact between the metal dome in the steering wheel and the contact ring. Although this design is simple and effective, it exposes many disadvantages in actual application.

[0003] First, from the perspective of pedestrian experience, the high-decibel sound of traditional horns is often sudden and causes unnecessary fright to pedestrians. On urban roads, pedestrians are one of the traffic participants, and their safety and feelings are equally important. However, due to the lack of volume adjustment mechanism in traditional horns, drivers often find it difficult to grasp the right degree when using them, resulting in pedestrians being frequently disturbed by high-volume horn sounds, which not only affects their mood, but may also cause unnecessary panic and conflicts, especially in areas with dense traffic, such as schools, hospitals, residential areas, etc., where high-volume horn sounds have become a serious noise pollution; secondly, from the perspective of drivers From a personal perspective, the use of traditional horns also has certain limitations. In daily driving, drivers may need to use horns to alert other vehicles or pedestrians, but not all situations require the use of high-volume horn sounds. For example, on congested city roads, drivers may just want to use the horn to gently remind the vehicle in front to start or the vehicle behind to keep a safe distance. At this time, the use of a high-volume horn sound is obviously inappropriate. However, since traditional horns lack a multi-stage trigger mechanism, drivers are often forced to choose to use a high-volume horn sound, which not only wastes energy, but may also cause disgust from other drivers. Summary of the invention

[0004] The object of the present invention is to provide a two-stage speaker triggering structure to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A two-stage speaker triggering structure, comprising:

[0007] A steering wheel base, a steering wheel cover plate is movably mounted on the top of the steering wheel base, and a plurality of springs are connected between the steering wheel base and the steering wheel cover plate;

[0008] A trigger assembly is arranged inside the steering wheel base and the steering wheel cover plate. The trigger assembly includes a metal contact ring fixedly installed inside the steering wheel base, and two metal springs are fixedly installed inside the steering wheel cover plate.

[0009] Preferably, a connector is fixedly installed on one side of the steering wheel cover plate close to the spring, and two metal springs are fixedly installed on one side of the connector.

[0010] Preferably, the two metal springs are arranged in one high and one low position.

[0011] Preferably, the two metal spring sheets are both arranged corresponding to the metal contact ring.

[0012] Preferably, the metal contact ring is connected to the automobile circuit system so that the electrical signal is transmitted to the speaker system.

[0013] Preferably, the two metal springs are in contact with the metal contact ring, so that the speaker system forms a circuit loop and activates the speaker sound unit.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) The horn triggering structure of the present invention can respond quickly to the driver's operation. The two metal springs correspond to the circuit loop of one horn respectively. Pressing the steering wheel lightly will cause the lower metal spring to contact the metal contact ring and make the lower decibel horn sound. Pressing the steering wheel hard will cause both metal springs to contact the metal contact ring. At this time, both the normal decibel horn and the low decibel horn will sound. By pressing the steering wheel hard, the two horn sounding units are activated at the same time, and other vehicles and pedestrians are reminded with a higher decibel and stronger warning effect, thereby effectively avoiding the occurrence of traffic accidents. At the same time, due to the existence of the low-volume horn, the driver can also issue a slight sound reminder by pressing the steering wheel lightly in non-emergency situations, which will not cause disgust to other drivers and can effectively convey their intentions. This flexible way of using the horn not only improves the driving safety of the driver, but also promotes the harmony and order of road traffic.

[0016] (2) The present invention significantly reduces the fright and disturbance to pedestrians by lowering the horn volume in non-emergency situations. When the driver needs to remind pedestrians to pay attention, he only needs to lightly press the steering wheel to issue a low-decibel sound reminder, which not only achieves the purpose of reminder but also does not cause unnecessary panic to pedestrians. This humanized design not only improves the travel experience of pedestrians, but also promotes harmonious interaction between drivers and pedestrians.

[0017] (3) The present invention introduces a differentiated sound design, allowing the driver to choose the appropriate horn volume and mode according to different situations, thereby effectively reducing noise pollution. In non-emergency situations, the driver can choose to use a low-volume horn to alert other vehicles or pedestrians; in emergency situations, a high-volume horn can be used to ensure the effective communication of safety information. This flexible horn usage method not only helps to reduce the level of noise pollution, but also helps to improve the quality of life of urban residents. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Embodiment 1:

[0024] See also Figure 1 - Figure 3 As shown, a two-stage speaker trigger structure includes:

[0025] A steering wheel base 1, a steering wheel cover 11 is movably mounted on the top of the steering wheel base 1, and a plurality of springs 12 are connected between the steering wheel base 1 and the steering wheel cover 11;

[0026] The trigger component 2 is arranged inside the steering wheel base 1 and the steering wheel cover 11 . The trigger component 2 includes a metal contact ring 21 fixedly installed inside the steering wheel base 1 . Two metal springs 23 are fixedly installed inside the steering wheel cover 11 .

[0027] Specifically, a connector 22 is fixedly installed on one side of the steering wheel cover 11 near the spring 12, and two metal springs 23 are fixedly installed on one side of the connector 22. The two metal springs 23 are positioned one high and one low, and the two metal springs 23 are arranged corresponding to the metal contact ring 21. The metal contact ring 21 is connected to the automobile circuit system so that the electrical signal is transmitted to the speaker system. The two metal springs 23 are in contact with the metal contact ring 21, so that the speaker system forms a circuit loop and activates the speaker sound unit.

[0028] As can be seen from the above, the spring 12 is a necessary structure of the steering wheel and is a prior art, which will not be elaborated here. The metal spring 23 and the metal contact ring 21 are also prior art. Pressing the steering wheel makes the metal spring 23 contact the metal contact ring 21 to realize the sound of the speaker. In this embodiment, there are two speaker sounding units, and the circuit structure of the two speakers is parallel. The volume of one speaker is lower than that of the normal speaker, and the two metal springs 23 correspond to the two speaker systems respectively. Since the heights of the two metal springs 23 are different, they are a low trigger spring and a high trigger spring respectively. The low trigger spring is located at a lower position, and the high trigger spring is located above it. The metal contact ring 21 is connected to the car circuit system and is responsible for transmitting electrical signals to the speaker system.

[0029] Working principle: When the driver presses the steering wheel lightly, only the low-trigger spring contacts the metal contact ring 21, forming a circuit loop, activating the low-volume speaker sound unit, and emitting a low-decibel sound as a friendly reminder or polite communication, reducing interference to pedestrians. In an emergency, the driver presses the steering wheel hard, and the high-trigger spring and the low-trigger spring contact the metal contact ring 21 at the same time, activating the two speaker sound units at the same time, the low-volume speaker continues to sound, and the high-volume speaker joins in at normal decibels, forming a strong warning signal together to ensure the effective communication of emergency information.

[0030] Embodiment 2:

[0031] For some models that hope to improve the driving experience and pedestrian-friendliness without changing the original steering wheel structure, this embodiment proposes a design scheme for adding an independent horn button in the cab. This design is particularly suitable for models with strict cost control or highly integrated steering wheel design.

[0032] Choose a place in the cab close to the driver (such as the blank area below the instrument panel, on the side of the center console, or below the steering wheel) that is easy to reach and does not affect driving operations, and install an independent horn button. The button must have clear markings and good tactile feedback so that the driver can quickly identify and accurately operate it during driving. Connect the independent horn button to the independent speaker output port of the vehicle audio system through a dedicated line. This independent speaker can be a low-volume speaker pre-installed somewhere in the vehicle, or a newly added speaker customized for the button. Ensure that the circuit connection is stable and reliable to avoid electromagnetic interference and short circuit risks. This structure can be used not only in motor vehicles, but also in non-motor vehicles. The principle structure does not change, and an independent horn button can be designed at the handle.

[0033] Embodiment three:

[0034] For vehicles that pursue the ultimate driving experience and operational convenience, this embodiment proposes a design of adding a horn button on the outer surface of the steering wheel. This design allows the driver to easily trigger the low-volume horn without changing the hand position during driving, thereby improving driving safety and comfort.

[0035] Select a suitable position on the outer surface of the steering wheel (such as the left or right edge of the steering wheel), use special tools to install and fix the horn button in place, ensure that the button is installed in a position that is convenient for the driver to operate and does not affect the overall appearance and safety of the steering wheel, and connect the newly added horn button to the independent horn output port of the vehicle audio system through a dedicated line (the same as the design of the above-mentioned independent horn button).

[0036] Embodiment 4:

[0037] The present invention can also realize a stepless trigger structure of the speaker based on the electronic stepless speed regulation switch, which can adjust the volume of the speaker in real time according to the force with which the driver presses the steering wheel button, thereby realizing more delicate and intuitive sound control.

[0038] Select an electronic stepless speed regulating switch with stable performance, fast response speed and high adjustment accuracy as the core component. The switch should be able to adjust its output state in real time according to the size of the input signal (such as voltage or current), so as to achieve stepless adjustment of the horn volume. Integrate the electronic stepless speed regulating switch into the control circuit of the vehicle horn system to ensure that the electrical connection between it and the steering wheel buttons, horn sound unit and other components is correct. At the same time, according to the specific circuit design and layout of the vehicle, arrange the installation position of the switch reasonably to facilitate the driver's operation and maintenance.

[0039] A pressure sensor is installed under the steering wheel button to detect the force of the driver pressing the button. The sensor should be able to convert the driver's pressing action into an electrical signal output, and the size of the signal is proportional to the pressing force. A signal processing circuit is designed to receive the output signal of the pressure sensor and convert it into a control signal that can be recognized by the electronic stepless speed regulation switch. The circuit should be able to filter out noise interference and improve the accuracy and stability of the signal.

[0040] When the driver presses the steering wheel button, the pressure sensor will output an electrical signal corresponding to the pressing force. After being processed by the signal processing circuit, the signal is sent to the electronic stepless speed control switch. The switch adjusts its output state in real time according to the size of the received signal, thereby controlling the power supply voltage or current of the speaker sound unit to achieve stepless adjustment of the volume. The vehicle horn system can adjust the volume in real time according to the force of the driver pressing the steering wheel button, realizing more delicate and intuitive sound control. This design not only improves the driver's driving experience and comfort, but also provides new ideas and directions for the safety and intelligent development of vehicles.

[0041] The following is a description of the application of this application in the urban public transportation system:

[0042] In a rapidly developing city, the public transportation system is an important artery for urban operation. Its safety and comfort are directly related to the travel experience of citizens. In order to further improve the safety of buses and the satisfaction of passengers and pedestrians, the urban public transportation system decided to introduce the structure of this application to optimize the use of bus horns, reduce noise pollution, and improve driving safety. The specific implementation steps are as follows:

[0043] S1, first, the steering wheel of the bus is modified, and two metal springs 23 (low trigger spring and high trigger spring) of different heights and a metal contact ring 21 are installed. At the same time, two independent speaker sounding units are installed inside the bus, corresponding to the low volume mode and the high volume mode respectively;

[0044] S2, integrate the control logic of the two-stage horn trigger structure into the bus control system, and realize the function of automatically selecting the horn sounding mode according to the driver's pressure by writing the corresponding control program;

[0045] S3, conduct special training for bus drivers, including the working principle, usage and application strategies of the two-stage horn triggering structure in different scenarios. Through simulation exercises and actual operation, drivers can master the skills of using the two-stage horn triggering structure and ensure that they can use it flexibly in actual driving;

[0046] S4, after sufficient testing and adjustment, buses equipped with a two-stage horn triggering structure will be officially put into operation;

[0047] S5, according to the actual driving situation, the driver lightly presses the steering wheel to sound the low-decibel horn, achieving the purpose of friendly reminder, and pedestrians can also feel the driver's intention. When encountering an emergency, the driver presses the steering wheel hard and both horns sound, alerting other vehicles and pedestrians with a higher decibel and stronger warning effect, thereby effectively avoiding traffic accidents.

[0048] Through the above implementation steps, the application of the two-stage horn trigger structure in the urban public transportation system has been smoothly promoted and achieved remarkable results. It not only improves the safety and comfort of buses, but also reduces noise pollution and improves the travel experience of citizens.
