[0019] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below in detail with reference to the accompanying drawings and embodiments.

[0020] System Example:

[0021] In order to solve the problems in the background technology, the utility model provides a multifunctional buzzer system for a loader, such as Figure 1 As shown:

[0022] It mainly consists of a buzzer 1 and a control box 2. The control box is connected to the buzzer 1 through the buzzer output terminal, and the power supply is connected to the control box 2 to power the entire loader multi-function buzzer system. In addition, the control box 2 is also connected to the control terminal for detecting the vehicle status. The control terminal includes a reverse control terminal and a reserved control terminal, which is used by the control box 2 to obtain the vehicle status. Specifically, the buzzer 1 is set outside the vehicle and the control box 2 is set in the cab. They are connected to the power supply and control terminals through the wiring harness 3 arranged throughout the vehicle. Figure 1 In the figure, the buzzer is connected to the wiring harness terminal 3.1 through the wiring terminal 1.2 of the transition wiring harness 1.1; the control box is connected to the wiring harness terminal 3.2 through the wiring terminal 2.2 on the control box transition wiring harness 2.1; the power supply is connected to the wiring harness terminal 3.3 through the wiring terminal of the transition wiring harness; and the control terminal is connected to the wiring harness terminal 3.4 through the wiring terminal of the transition wiring harness.

[0023] Among them Figure 2 The illustrated buzzer features a double-sided mounting hole structure and consists primarily of a buzzer body 1 and a transition harness 1.1. Different mounting surfaces can be selected depending on the specific situation. The buzzer boasts wide adaptability and multi-mode voice. This adaptability is reflected in its wide voltage range, which allows operation in environments ranging from 9V to 60V DC. It also boasts a sound level of 108±5dB and an IP67 waterproof rating, making it highly audible and suitable for various loader operating conditions. The multi-mode voice is also reflected in the controller's internal microcontroller, which generates AC power at varying frequencies to control the buzzer's various voice modes. These modes include "beep," "Reverse, please pay attention," and "Drive safely," which can be switched using the voice selection button 7 on the control box 2. Customers can also customize the voice modes by reprogramming the controller's microcontroller, such as "Left turn, please pay attention," or "Operation, please pay attention."

[0024] like Figure 3The control box shown is a snap-on structure, primarily consisting of a volume button / switch 4, a voice selection button 5, and a transition harness 2.1. It only requires drilling a hole for installation and can be conveniently placed anywhere. It features convenient switching, adjustable volume, multi-mode switching, and multi-mode control logic. The convenient switching and adjustable volume are reflected in the knob-type volume button / switch 4 on the control box. Rotating it clockwise switches it from off to on, and further rotation adjusts the volume from 0% to 100% of maximum volume. Rotating it counterclockwise adjusts the volume from 100% to 0%, and further counterclockwise rotation switches the switch state from on to off, disconnecting the buzzer circuit and preventing the buzzer from sounding. Multi-mode switching is reflected in the voice selection button 5 on the control box. It is a self-resetting structure. There are two voice modes under the reversing signal, namely the default "beep" sound and the "reversing, please pay attention" sound when pressed for the first time. Press it again to switch to the continuous driving mode of the whole vehicle, and the buzzer will emit a voice "vehicle driving, please pay attention to safety"; the multi-mode adjustable control logic is reflected in the two control logics of reversing signal triggering and vehicle driving continuous triggering, which can realize voice reminders when reversing and safety reminders when the vehicle is driving. This can be achieved through the voice selection button, and all the above voice mode states are automatically latched after power failure, and will be in the latched state when powered on next time. There is no need to switch multiple times, which is very convenient.

[0025] like Figure 4 The figure shows the wiring harness connection diagram for the control box. All functions are realized by simply drawing power externally and correctly connecting the control box and buzzer. The wiring harness design is simple and highly reliable. In addition, the control box has a reserved control terminal that can be used to detect the vehicle's driving status, such as connecting a driving detection signal. Specifically, the driving detection signal includes a speed signal and a gear position signal. When the speed signal is non-zero and the gear is in forward gear, the vehicle is considered to be in motion, and the buzzer will emit a driving safety reminder voice, such as "Vehicle driving, please pay attention to safety."
