Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of warning devices for new energy vehicles, in particular to a pedestrian warning device for new energy vehicles. BACKGROUND

[0002] The warning device refers to a sound unit for sounding and warning. New energy vehicles do not include driving components such as engines, so the sound emitted by new energy vehicles during driving is too small to attract the attention of pedestrians, which may lead to collision hazards. The warning device sounds during low-speed driving of new energy vehicles to alert pedestrians of the approaching vehicle.

[0003] The utility model with publication number CN220220568U discloses a sound channel pipe device for pedestrian warning of new energy vehicles. The sound channel pipe device has the functions of reducing sound pressure loss, improving sound stability and reliable precision, and provides a set of early warning device for pedestrians and drivers when new energy vehicles are driving at low speed, greatly improving the safety of new energy vehicles when driving at low speed.

[0004] The utility model with publication number CN208291076U discloses a low-speed pedestrian reminder for electric vehicles. The waterproof and air-permeable membrane is arranged at the air-permeable hole of the low-speed pedestrian reminder for electric vehicles to ensure the waterproof and air-tightness of the low-speed pedestrian reminder for electric vehicles. The upper shell and the lower shell are connected by a snap-fit structure, which is convenient for assembly and maintenance.

[0005] However, the above-mentioned warning device for low-speed driving of new energy vehicles has the following problems in actual use: although the buzzer sound unit arranged inside the shell is used to warn pedestrians, the sound and sound amplification directions of such warning devices are single, and some pedestrians may not notice the warning of the warning device due to environmental influences. In addition, the new energy vehicle warning device is installed at the lower position, which may be affected by water when the vehicle is driving in water, affecting the normal operation and service life of the warning device.

[0006] Therefore, we propose a pedestrian warning device for new energy vehicles to solve the above-mentioned problems. SUMMARY

During the water driving process, the buoyancy horizontal plate at the bottom moves upward, the abutting push arc plate moves upward, and the push arc plate slidingly arranged in the guide sliding groove arranged on the bottom surface of the abutting ring, so that the push arc plate can drive the abutting ring and the abutting column to rise, and it will not be affected by the abutting ring, ensuring the normal warning work of the loudspeaker shell.

[0024] The conflict column drives the sealing sliding disc and the sealing plug column connected to the upper part to move upward, and then the sealing plug column blocks the sound amplification slot hole in the sound amplification shell, thereby avoiding the influence of the service life of the loudspeaker unit and the main control circuit board when splashing into the warning device.
