Problems solved by technology

However, if the speaker is installed at the rear of the vehicle, the warning sound from there is absorbed by the rear seat, for example, so that the sound pressure reaching the driver is reduced, so it is also possible that the driver's judgment is delayed.

Embodiment approach 1

[0033] figure 1 , 2 The rear configuration of the vehicle 2 is shown, in particular the configuration of the hatchback 4 . Rear seats 6 are arranged in front of the tailgate 4 , and a luggage compartment 10 constituting a part of the cabin 8 is formed between the tailgate 4 and the rear seats 6 .

[0034] Additionally, the present invention is not limited to liftback tailgates. As we all know, the opening and closing methods of the tailgate 4 are hatchback, side-opening and double-opening, and the present invention is also applicable to side-opening and double-opening tailgates.

[0035] The tailgate 4 of this embodiment includes a hinge mechanism (not shown) on the upper end of the tailgate 4 and the corresponding vehicle body, and the tailgate 4 can be lifted (opened) relative to the vehicle body by the hinge mechanism. In addition, a lock mechanism (not shown) is provided in a vehicle body portion corresponding to the lower end of the tailgate 4 , and the tailgate 4 can ...

Embodiment approach 2

[0046] In Embodiment 1 above, one speaker is arranged at the center position in the vehicle width direction, but if Figure 5 As shown, the two speakers 70 may be arranged substantially symmetrically. As described in Embodiment 1, the arrangement of each speaker 70 is preferably such that the sound emitted by the speaker 70 is reflected by the tailgate glass 20 and travels beyond the upper part of the rear seat to the front thereof. At this time, the traveling direction of the reflected sound is as described in Embodiment 1, and it is preferable to travel in a direction higher than the horizontal plane.

[0047] Specifically, in Embodiment 2, two brackets 72 are fixed to the inner panel 22 , and the two brackets 72 are substantially bilaterally symmetrical, and speakers 70 are respectively fixed to the brackets 72 . Like Embodiment 1, the bracket 72 is preferably fixed on the inner panel 22 through several fastening points, more preferably fixed on the inner panel 22 through ...

Abstract

The invention provides a vehicle back door, a vehicle warning method and a system. A loudspeaker is arranged on the back door and sends a warning sound as large as possible to a position in the frontpart of a vehicle interior. The vehicle back door 4 includes a back door main body 12 having a window opening 18 and a back door pane 20 attached to the window opening. The back door main body has a speaker 38. The speaker is disposed below the back door pane and the angle [alpha]1 formed by a vehicle height direction axis 42 and a central axis 40 of the speaker is set to a value smaller than theinclination angle [alpha]2 of the back door pane with respect to the vehicle height direction axis. Accordingly, the sound emitted by the speaker is reflected by the back door pane and then transmitted to the front part of the vehicle interior.

Description

technical field [0001] The invention relates to a vehicle tailgate, a vehicle warning method and a system. Background technique [0002] Patent Document 1 discloses an assist system. When the shift lever of the vehicle is set to go backward, when a sensor located at the rear of the vehicle detects an obstacle behind the vehicle, the assist system will activate The speaker next to the passenger seat emits a warning tone. [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Patent Laid-Open No. 2000-177512. [0006] From a more realistic point of view, preferably, an alarm sound is emitted from the rear of the cockpit when alerting attention to the existence of an obstacle behind the vehicle. This is to make it easy for the front seat occupants (especially the driver) to intuitively understand that there is a risk of collision on the rear side. However, if the speaker is installed at the rear of the vehicle, the warning sound from t...
