Detailed Description

Embodiments of the present invention will be described in detail below, the embodiments described with reference to the drawings being illustrative, and the embodiments of the present invention will be described in detail below.

A cab 1 of a vehicle 2 according to an embodiment of the present invention is described below with reference to fig. 1 to 4, the cab 1 being provided on the vehicle 2, and the vehicle 2 being an electric truck.

As shown in fig. 1 and 2, a cab 1 of a vehicle 2 according to an embodiment of the present invention includes: a dash panel 10, a back panel 20, a left side panel 30, and a right side panel 40. The dash panel 10 is disposed at the front side of the cab 1, and the dash panel 10 may be used to mount a front windshield, through which a driver can see the road condition ahead. The back panel 20 is disposed at the rear side of the cab 1, the back panel 20 may perform an installation and fixing function, and an air conditioner external unit of the vehicle 2 may be fixed at the outer side of the back panel 20. The left and

right coamings

30 and 40 are disposed on left and right sides of the cab 1, and the left and

right coamings

30 and 40 are respectively provided with a left door and a right door, so that a driver in the cab 1 can get in and out of the cab 1 through the left door and the right door.

As shown in fig. 1 and 2, the back panel 20 is disposed opposite to the front panel 10 in the front and rear direction, and a sufficient space is left between the back panel 20 and the front panel 10, so that a sufficient facility space and a movement space for the primary driver and the secondary driver are available in the front and rear direction of the cab 1, and in addition, the left side panel 30 and the right side panel 40 are respectively disposed between the front panel 10 and the back panel 20, so that a specific space of the cab 1 can be defined, and the space should meet normal requirements, and by such arrangement, the structure of the cab 1 can be more reasonable and meet the requirements of regulations.

Wherein, as shown in fig. 1 and fig. 2, the dash panel 10 is constructed as an arc-shaped panel with a front convex middle part, that is, the middle part of the front baffle is convex outwards, when the vehicle 2 moves forwards, the convex part of the middle part of the front baffle can be in contact with the air flow before the cab 1, the dash panel 10 is constructed as an arc-shaped panel, the arc-shaped structure has better diversion effect, so that the air flow can be guided to the two sides of the cab 1 along the arc-shaped structure of the arc-shaped panel, thereby reducing the contact of the air flow and the main body part of the cab 1, and further reducing the air resistance encountered when the vehicle 2 moves.

As shown in fig. 1 and 2, it should be noted that, in the prior art, the wind resistance coefficient of the water drop is the lowest and is only 0.05, the wind resistance coefficient of the vertical plane object is the highest and is 1.0, and the wind resistance coefficient of the common truck is about 0.6-0.8, and the truck encounters a larger wind resistance. In the front-to-rear direction, each of the left and

right coamings

30 and 40 is configured as an arc gradually protruding outward, that is, the length of the dash panel 10 in the left-to-right direction of the cab 1 is smaller than the length of the dash panel 20 in the left-to-right direction of the cab 1, and each of the left and

right coamings

30 and 40 is configured as an arc gradually protruding outward between the dash panel 10 and the dash panel 20.

As such, the overall shape of cab 1 may resemble a "water-drop" or "bullet" shape in plan view, and a "water-drop" or "bullet" shaped cab 1 may reduce wind resistance. Specifically, when vehicle 2 moves forward, the air current can be earlier than dash panel 10 contact, and dash panel 10 is less in the length of the left and right sides direction of driver's cabin 1, reduce the windward side of driver's cabin 1 like this, most air current can contact with dash panel 10 left side bounding wall 30 and right side bounding wall 40 of the left and right sides, left side bounding wall 30 and right side bounding wall 40 are all constructed as the convex arc of outside gradually again, and is same, the arc structure has better water conservancy diversion effect, the air current can be guided to the rear side of driver's cabin 1 along the arc structure of arc always, thereby can reduce the air current and the main part contact of driver's cabin 1, and then can reduce the air resistance that meets when vehicle 2 moves.

From this, through in the direction from the front to the back, all construct left coaming 30 and right coaming 40 for the convex arc in outside gradually, the whole appearance of driver's cabin 1 can be similar to "water droplet" form or "bullet head" form like this, and left coaming 30 and right coaming 40 have better water conservancy diversion effect to can reduce vehicle 2's air resistance coefficient, reduce air resistance, and then can promote vehicle 2's whole dynamic nature and economic nature.

As shown in fig. 1 and 2, the dash panel 10 and the left side panel 30 are in arc transition, and the dash panel 10 and the right side panel 40 are in arc transition. Through the circular arc transition of the front coaming 10 and the left coaming 30 and the right coaming 40, the connection between the front coaming 10 and the left coaming 30 and the right coaming 40 can be smoother and more natural, and when the air current contacts the front coaming 10, part of the air current can be guided to the left coaming 30 and the right coaming 40, so that the air resistance of the front coaming 10 can be reduced, and further the whole air resistance of the vehicle 2 is reduced.

Of course, as shown in fig. 1 and 2, the cab 1 of the vehicle 2 further includes: the cowl panel 10 is provided with a flow guide portion 11, an upper end of the flow guide portion 11 is connected to the cowl panel 50, and the flow guide portion 11 is configured as an arc portion extending rearward in a direction from below.
