the windshield 30 provided to the meter housing 10, as shown in fig. 3, has a front panel and a rear panel in the traveling direction of the electric vehicle (as indicated by the solid arrow in fig. 3), the rear panel being provided with a sound pickup hole a connected to the opening of the microphone 20; the windshield 30 further has a first panel and a second panel disposed opposite to each other, and the second panel is disposed obliquely to the first panel, and a distance between a front end of the first panel and a front end of the second panel is smaller than a distance between a rear end of the first panel and a rear end of the second panel.
The present embodiment provides an electric vehicle meter, and specifically please refer to fig. 2 and fig. 3 continuously, the electric vehicle meter provided in the present embodiment includes a meter housing 10, a microphone 20, and a windshield 30, wherein the microphone 20 and the windshield 30 are both disposed in the meter housing 10. Since the electric vehicle meter is generally mounted on an electric vehicle, the windshield 30 has a front panel and a rear panel disposed opposite to each other and a first panel and a second panel disposed opposite to each other in a traveling direction of the electric vehicle (as indicated by solid arrows in fig. 3). When the user rides the electric vehicle, the direction of the wind moving relative to the vehicle (as indicated by the arrow of the broken line in fig. 3) is opposite to the traveling direction of the electric vehicle (as indicated by the arrow of the solid line in fig. 3), and thus it can be observed in conjunction with fig. 3 that the wind directly acts on the front panel of the windshield 30. After the wind acts on the front panel of the windshield 30, the wind can move in the direction of the first panel and the second panel toward the rear panel. It is noted that the second panel is obliquely arranged relative to the first panel, and the distance between the front end of the first panel and the front end of the second panel is smaller than the distance between the rear end of the first panel and the rear end of the second panel. In other words, the first panel and the second panel are in a splayed state. Therefore, with reference to fig. 3, the first panel and the second panel can guide the wind to a position away from the sound pickup hole a along the direction c in fig. 3.
The electric vehicle instrument that this application embodiment provided can reduce the amount of wind that flows in-process infiltration pick-up hole A through the wind-guiding effect of first panel and first panel to improve the awakening rate of electric vehicle instrument in the motion process.
It should be understood that the first and second panels can be one of the top panels of the windshield 30 and the other of the bottom panels of the windshield 30. Of course, the first and second panels may also be one left side panel of the windshield 30 and the other right side panel of the windshield 30.
The first panel and the second panel are a top panel and a bottom panel of the windshield 30, respectively, and will be described below as an example.
Referring to fig. 3, specifically, the first panel and the second panel diverge the wind direction in two directions, the top surface is inclined upward, the bottom surface is inclined downward, so as to guide the wind direction from the top surface and the bottom surface away from the sound pickup hole a, thereby preventing the wind from converging in front of the sound pickup hole a to form a vortex.
On the basis of the above technical solution, in order to improve the air guiding capability of the first panel and/or the second panel, as a preferred embodiment, please refer to the structure shown in fig. 4, the first panel and/or the second panel is provided with at least one air guiding groove 32, and the air guiding groove 32 connects the front panel and the rear panel.
It is noted that the first panel and the second panel may be provided with air guiding grooves 32, for example, as shown in fig. 4, two air guiding grooves 32 are provided on each side of the first panel and the second panel. It should be understood that the distance between the bottom of the air guiding groove 32 on the first panel and the bottom of the air guiding groove 32 on the second panel increases gradually from the front panel to the rear panel. In other words, the wind guide grooves 32 on the first panel and the wind guide grooves 32 on the second panel also guide the wind in a direction away from the sound pickup hole a to reduce the influence on the sound pickup hole a.
On the basis of the technical scheme, the sound pickup hole A is formed in the center of the rear end panel. Of course, the sound pickup hole a may be disposed at an approximate center instead of the center, and may be specifically disposed according to requirements, which is not described herein again.
In order to further reduce the occurrence of the phenomenon that the wind enters the sound pickup hole a along the edge position when the wind flows in the guiding direction, please continue to refer to the structure shown in fig. 4, the rear panel of the windshield 30 is provided with a sinking platform 31, and the sound pickup hole a is arranged on the sinking platform 31.
Of course, there will be some wind from the rear panel acting on the windshield 30 during the travel of the electric vehicle, and preferably, with continued reference to the configuration shown in fig. 4, the windshield 30 may be provided with a windshield 40 to filter and decelerate wind from this direction. Specifically, the windproof net 40 is mounted to the sinking platform 31. Illustratively, the windproof net 40 is attached to the bottom of the sinking platform 31.
In addition to the above technical solution, fig. 5 is a structural diagram observed along a direction d in fig. 4, and as shown in the structure of fig. 5, the windshield 30 further includes a third panel and a fourth panel which are oppositely arranged, and the first panel, the third panel, the second panel and the fourth panel are sequentially connected to form a ring structure. In order to further optimize the windshield 30 provided in the embodiment of the present application, it is possible to provide: the fourth panel is obliquely arranged relative to the third panel, and the distance between the front end of the fourth panel and the front end of the third panel is smaller than the distance between the rear end of the fourth panel and the rear end of the third panel.
It is worth noting that an outer splayed structure is also formed between the third panel and the fourth panel, and the wind acting on the third panel and the fourth panel can be guided to the direction far away from the sound pickup hole A, so that the influence on the sound pickup hole A is further reduced.
It should be noted that the windshield 30 can be individually assembled on the meter according to the shape and assembly manner of the electric vehicle meter, so as to facilitate the design of different guiding angles and heights of the side walls of the air guiding groove 32 for the windshield 30. Illustratively, as shown in fig. 3, the windshield 30 is removably attached to the meter housing 10.
If the electric vehicle instrument space size is enough, the instrument shell 10 can be integrated together to form an integrated structure, so that the cost is reduced.
An audio transmission channel B, as shown in fig. 2 and 3, may also be provided in the meter housing 10, and connects the outlet of the microphone 20 and the sound pickup hole a.
In a second aspect, an embodiment of the present application further provides an electric vehicle, where the electric vehicle is equipped with the electric vehicle meter in any of the above-mentioned first aspects.
It is worth noting that the electric vehicle provided by the embodiment of the application is provided with the electric vehicle meter provided by the embodiment of the application, and the electric vehicle meter can reduce wind resistance and weaken the influence of wind noise on voice interaction in a motion state, so that the voice awakening recognition probability of the electric vehicle meter in a high-speed motion state of the electric vehicle can be realized, and voice interaction awakening and recognition in a motion mode can be realized.
