Abstract

The utility model belongs to vehicle arrangement technical field, and in particular to a kind of vehicle front windshield.Vehicle front windshield described in the utility model, bottom surface, first side, second side and top surface including windshield main body and around the windshield main body, the intermediate position of the bottom surface convexes to form and the matched arcwall face of hood of vehicle to the direction of the top surface, and the position of the peak of the arcwall face is higher than the first side and the second side position with the bottom surface junction respectively, to reduce windage.By using vehicle front windshield described in the utility model and vehicle, the middle and lower part of front windshield is improved, be conducive to drive room conditioning and enging cabin arrangement, the connection angle of front windshield and hood after improving simultaneously increases, the intermediate position air-flow for reducing windscreen generates turbulent flow, reduces windage.

Description

Vehicle front windshield and vehicle

Technical field

The utility model belongs to vehicle arrangement technical field, and in particular to a kind of vehicle front windshield and vehicle.

Background technology

Generally there are four angles for existing front windscreen for vehicle, as shown in Figure 1, the position of middle and lower part is relatively low, and driver's cabin Engine in interior air-conditioning and enging cabin is arranged in the centre position at Chinese herbaceous peony end, therefore existing windscreen is not Conducive to the arrangement of vehicle.

By the CFD of vehicle analysis shows, the connection of existing front windscreen for vehicle and hood at intermediate position Angle is smaller, causes the intermediate position air-flow of windscreen to generate turbulent flow, forms the first turbulent region A；Existing car front windshield windscreen The top both sides of glass are relatively flat, are hardly formed wedge angle with body side wall, form the second turbulent region B and third turbulent region C.The The presence of one turbulent region A, the second turbulent region B and third turbulent region C result in the increase of vehicle windage.

Utility model content

Purpose of the utility model is to solve above-mentioned at least one problem, which is by following technology What scheme was realized.

The utility model proposes vehicle front windshield, including windshield main body and it is located at the windshield The direction of bottom surface, first side, second side around main body and top surface, intermediate position to the top surface of the bottom surface is raised Formation and the matched mating surface of hood of vehicle, to reduce windage.

Further, the mating surface is arcwall face.

Further, the position of the peak of the arcwall face higher than the first side and the second side respectively with The position of the bottom surface junction.

Further, the top of the first side and the top of the second side are respectively to the middle part of the top surface Position is drawn close, to make the lengthwise dimension of the top surface reduce.

Further, it is equipped with rubber stop glue on the bottom surface, the first side, the second side and the top surface Item.

The utility model also proposed a kind of vehicle, including vehicle front windshield described above.

By using vehicle front windshield described in the utility model and vehicle, the middle and lower part of front windshield is carried Height is conducive to drive room conditioning and enging cabin arrangement, while the joint angle of the front windshield and hood after raising Degree increases, and the intermediate position air-flow for reducing windscreen generates turbulent flow, reduces windage.

By using vehicle front windshield described in the utility model and vehicle, behind the First Point of front windshield It moves, so as to driver's cabin integral forward lead, the space availability ratio of headstock is improved, and reduce the generation of vehicle body both sides turbulent flow, to drop Low windage.

Description of the drawings

By reading the detailed description of hereafter preferred embodiment, various other advantages and benefit are common for this field Technical staff will become clear.Attached drawing only for the purpose of illustrating preferred embodiments, and is not considered as to this practicality Novel limitation.And throughout the drawings, the same reference numbers will be used to refer to the same parts.In the accompanying drawings：

Fig. 1 is the structural schematic diagram of front windshield in the prior art；

Fig. 2 is the structural schematic diagram of the vehicle front windshield in the present embodiment.

Respectively label indicates as follows in attached drawing：

10：Windshield main body, 11：Bottom surface, 12：First side, 13：Second side, 14：Top surface；

A：First turbulent region, B：Second turbulent region, C：Third turbulent region.

Specific implementation mode

The illustrative embodiments of the disclosure are more fully described below with reference to accompanying drawings.Although showing this public affairs in attached drawing The illustrative embodiments opened, it being understood, however, that may be realized in various forms the disclosure without the reality that should be illustrated here The mode of applying is limited.It is to be able to be best understood from the disclosure on the contrary, providing these embodiments, and can be by this public affairs The range opened completely is communicated to those skilled in the art.

Fig. 2 is the structural schematic diagram of the vehicle front windshield in the present embodiment.As shown in Fig. 2, vehicle front windshield Glass includes windshield main body 10 and the bottom surface 11 around windshield main body 10, first side 12, second side 13 and top surface 14.The intermediate position of bottom surface 11 convexes to form and the matched cooperation of hood of vehicle to the direction of top surface 14 Face, to reduce windage.

The middle and lower part of front windshield is improved, is conducive to the arrangement for driving room conditioning and enging cabin, improves simultaneously The connection angle of front windshield and hood afterwards increases, and the intermediate position air-flow generation for reducing windscreen is disorderly Stream reduces windage.

In the present embodiment, turbulent flow is generated to be further reduced the intermediate position air-flow of front windshield, mating surface is set Set arcwall face.

In order to further enhance the space availability ratio of front of the car, the position of the peak of arcwall face is higher than first side 12 With the position with 11 junction of bottom surface respectively of second side 13, consequently facilitating driving the arrangement of room conditioning and enging cabin.

Further, the top surface of first side 12 and the top of second side 13 are leaned on to the intermediate position of top surface 14 respectively Hold together, to make the lengthwise dimension of top surface 14 reduce.

The top surface size of front windshield is reduced, to form three-dimensional wedge angle with driver's cabin gusset and head cover, is reduced The generation of vehicle body both sides turbulent flow, to reduce windage.

Since the intermediate position of the bottom surface 11 of front windshield is arranged to arcwall face, the entirety of front windshield is increased Faying face length, to increase the bonding strength of front windshield and car body.

Further, it is all provided on the bottom surface 11 of vehicle front windshield, first side 12, second side 13 and top surface 14 There is rubber stop adhesive tape.

The preferable specific implementation mode of the above, only the utility model, but the scope of protection of the utility model is not It is confined to this, any one skilled in the art within the technical scope disclosed by the utility model, can readily occur in Change or replacement, should be covered within the scope of the utility model.Therefore, the scope of protection of the utility model should be with Subject to the scope of the claims.
