Description

Technical Field

[0001] This utility model relates to the field of horn control technology, and in particular to a horn control system for an electric two-wheeled vehicle. Background Technology

[0002] Electric two-wheelers have become the preferred mode of transportation for many people due to their low price, lightweight design, ease of use, and wide applicability on various roads.

[0003] The horn, turn signals, and alarm of an electric two-wheeler are all independently operated. While traditional electric two-wheeler horns use iron horns, which have high sound pressure levels and a clear, crisp sound, their drawbacks are also obvious:

[0004] 1. The iron horn has a limited timbre and can only produce a fixed sound;

[0005] 2. Meanwhile, the turn signal, remote control prompts, and alarm prompts are two independent sound-emitting structures, requiring the configuration of horns and buzzers to produce sound, and also requiring separate control. This undoubtedly increases the usage cost and the workload of vehicle assembly and wiring for vehicle manufacturers. Utility Model Content

[0006] The purpose of this utility model is to solve the problems existing in the prior art by proposing a horn control system for electric two-wheeled vehicles.

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

[0008] An electric two-wheeled vehicle horn control system includes:

[0009] A piezoelectric loudspeaker uses a piezoelectric ceramic disc as a sound-producing unit, and can emit sound by driving a signal.

[0010] A multi-effect piezoelectric horn driver includes a drive module. The drive module is connected to the control system of an electric two-wheeled vehicle through several level selection ports and can realize several different output signals. The output end of the drive module is electrically connected to the piezoelectric horn and is used to send drive signals to the piezoelectric horn.

[0011] Preferably, the electric two-wheeler control system includes a control module and a switch assembly, wherein the switch assembly is electrically connected to the low beam headlight, piezoelectric horn, turn signal, high beam headlight, low beam headlight, and brake light through the control module.

[0012] Preferably, it also includes a storage battery, which is electrically connected to the electric two-wheeler control system and the multi-effect piezoelectric horn driver.

[0013] Preferably, the battery is electrically connected to the electric two-wheeler control system and the multi-effect piezoelectric horn driver via a DC-DC step-down module.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention uses a single piezoelectric horn in conjunction with a multi-effect piezoelectric horn driver, which can replace the iron horn of traditional electric vehicles and output several different output signals to achieve multiple sound effects. It solves the problem that in the prior art, the iron horn has a single timbre and can only produce a fixed sound. Furthermore, turning, remote control prompts, and alarm prompts require separate control, which increases costs. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example 1

[0021] An electric two-wheeled vehicle horn control system includes:

[0022] A piezoelectric loudspeaker uses a piezoelectric ceramic disc as a sound-producing unit, and can emit sound by driving a signal.

[0023] like Figure 1 and Figure 2As shown, the multi-effect piezoelectric speaker driver includes a driver module. The driver module has ten connection ports: VDD, OUT2, OUT1, PEND / GND, DIN, VDD / VR, VSS, P60, P61, and P62. OUT2 and OUT1 are connected to the positive and negative terminals of the piezoelectric speaker respectively through 24R resistors R6 and R7, and resistors R9 and R10. VDD is connected to a 12V battery, which is grounded through a 10uF / 25V capacitor EC1 and a 0.1uF capacitor C5. PEND / GND is grounded. VDD / VR and VSS are connected to the two ends of a 1uF capacitor C8, with C8 close to VSS. With one end grounded, the drive module is connected to the electric two-wheeler control system through three level selection ports: P60, P61, and P62. Each level selection port has an external pin set to 0 and 1 levels, which can realize up to 8 different output signals. The output end of the drive module is electrically connected to the piezoelectric horn to send drive signals to the piezoelectric horn. The multi-effect piezoelectric horn driver can have multiple built-in horn sounds, such as turn signals, lock signals, unlock signals, and alarm signals. With the level selection ports, different horn sound effects can be output.

[0024] In this embodiment, the battery is electrically connected to the electric two-wheeler control system and the multi-effect piezoelectric horn driver via a DC-DC step-down module.

[0025] In this embodiment, the electric two-wheeled vehicle control system includes a control module and a switch assembly. The switch assembly is electrically connected to the low beam headlight, piezoelectric horn, turn signal, high beam headlight, low beam headlight, and brake light through the control module.

[0026] In actual use, when the electric vehicle key is inserted into the lock and started, the unlocking recognition port of the electric two-wheeler control system detects the unlocking status and sends a level signal corresponding to the unlocking sound effect to the multi-effect piezoelectric horn driver. After receiving the signal, the multi-effect piezoelectric horn driver generates a corresponding sound effect driving signal to drive the piezoelectric horn to emit the unlocking sound effect.

[0027] During operation, when the horn needs to be sounded, pressing the horn button will cause the electric two-wheeler control system to detect the horn's level signal and quickly send the corresponding selection level to the multi-effect piezoelectric horn driver, thereby driving the piezoelectric horn to emit a horn sound.

[0028] If a turn is required while driving, in addition to illuminating the corresponding turn signal, the piezoelectric horn will also emit a warning sound synchronized with the turn signal.

[0029] In addition, the vehicle enters anti-theft alarm mode after being locked. When the alarm button on the remote control is pressed, if the vehicle is moved illegally, the electric two-wheeler control system will use a multi-effect piezoelectric horn driver to make the piezoelectric horn emit an alarm sound, thus serving as a warning.

[0030] This allows for a unified structure for steering, remote control prompts, and alarm prompts, eliminating the need for horns and buzzers and separate control. This reduces usage costs and the workload of vehicle assembly and wiring for vehicle manufacturers.

[0031] Example 2

[0032] like Figure 3 As shown, the difference between this embodiment and Embodiment 1 is that:

[0033] This embodiment uses a 48-60V battery for direct power supply, and a step-down module is required in the middle. The step-down module includes a 200Ω resistor in series and a 5.1V diode. Other sound effect control parts are the same as the 12V application version.

[0034] This control system operates within a wide voltage range of 12-60V.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
