Problems solved by technology

[0002] When HEV and EV vehicles are driven by electric motors (EV running), the sound produced by the vehicle is very small compared with conventional internal combustion engine vehicles, and sometimes it is impossible to convey information about the approach of the vehicle to pedestrians, etc. It senses the approach of the vehicle

Embodiment Construction

[0047] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0048] figure 1 It is a cross-sectional view of an embodiment of a vehicle sound generating device provided on a differential device, figure 2 It is a perspective view of the impact member mounted on the differential case and the vibrating plate mounted on the transmission case.

[0049] Such as figure 1 with figure 2 As shown, the sound generating device 10 for a vehicle has a pair of striking members 20 and a vibrating plate 30 , and the sound generating device 10 for a vehicle is provided on a differential gear device 50 .

[0050] First, the differential device 50 will be described. The differential device 50 is a device that transmits rotation of a driving source (not shown), such as an engine, to driving wheels (not shown) while absorbing a rotation difference. A differential case (hereinafter referred to simply as a differential case) 51 of the differe...

Abstract

A vehicle sound generator 10 includes a transmission case 52, a differential case 51 rotatable with respect to the transmission case 52, a striking member 20 disposed on the differential case 51, and a vibration plate 30 disposed on the transmission case 52. The striking member 20 is disposed so as to come in contact with the vibration plate 30 when the differential case rotates. The rotation of the differential case allows the striking member and the vibration plate to generate a striking sound. Therefore, the vehicle proximity sound can be made in a mechanical manner, and the reliability is higher.

Description

technical field [0001] The present invention relates to a sound generating device for a vehicle capable of emitting a notification sound for recognizing the approach of a vehicle with a quiet running sound, such as a vehicle running with an electric motor as a driving source, approaching. Background technique [0002] When HEV and EV vehicles are driven by electric motors (EV running), the sound produced by the vehicle is very small compared with conventional internal combustion engine vehicles, and sometimes it is impossible to convey information about the approach of the vehicle to pedestrians, etc. It senses the approach of a vehicle. Therefore, among conventional HEV and EV vehicles, there is known a vehicle that emits a vehicle approach notification sound (notification sound) in the form of an electronic sound from a speaker (for example, refer to Patent Document 1). The vehicle approach notification sound control device described in Patent Document 1 can respond to th...
