In order to solve the above-mentioned problems, the present invention provides a flow guiding structure for being disposed on the front side of a windshield, and fig. 1 to 6 are specific embodiments of the flow guiding structure provided by the present invention.

Referring to fig. 1 to 3, the flow guiding structure 100 includes a flow guiding plate 1 extending in a left-right direction, the flow guiding plate 1 includes a first flow guiding section 1113, a second flow guiding section 12, and a third flow guiding section, the first flow guiding section 1113 extends in a front-back direction, the third flow guiding section extends obliquely upward from front to back, a front end of the second flow guiding section 12 is connected with a rear end of the first flow guiding section 1113, a rear end of the second flow guiding section 12 is connected with a front end of the third flow guiding section, and the third flow guiding section is used for guiding an air flow sequentially passing through the first flow guiding section 1113 and the second flow guiding section 12 upward.

In the technical scheme provided by the invention, the guide plate 1 is arranged at the front side of the windshield 200, the third guide section is upwards inclined, when the vehicle speed is higher, the third guide section can change the direction of the air flow, and apply a Z-direction upward force to the air flow, so that insects in the range change the original movement track, and after receiving the Z-direction upward force, the Z-direction height of the insect flying process can be higher, and the insect flying process leaves the visual field of the driver before reaching the front windshield 200, so that the interference on the sight of the driver is reduced, and the guide structure 100 capable of avoiding flying insect shielding or being adsorbed on the windshield 200 is provided.

And moreover, only by arranging the guide plate 1, the structure is simple, the cost is low, and the failure rate is low. During installation, other parts of the vehicle body are not required to be improved and damaged, and the original service performance is not affected.

Further, in order to enable the airflow to smoothly transition to the third flow guiding section, in this embodiment, the upper surface of the second flow guiding section 12 is configured as an arc surface. The second guiding section 12 performs arc transition when guiding the airflow flowing along the front-back direction to the third guiding section.

Further, in order to facilitate installation, in this embodiment, the baffle 1 is formed with a slot 1a, and the slot of the slot 1a is disposed forward. The baffle 1 is clamped at the rear end of the engine cover 300 through the clamping groove 1a, and is matched with the front water flowing groove, and it is understood that the size of the clamping groove 1a depends on the wall thickness of the engine cover 300, and the size of the clamping groove 1a is smaller than the thickness of the engine cover 300 in order to enable the baffle 1 to be stably clamped. And through the mode of clamping, when dismantling is required, can conveniently demolish baffle 1.

Specifically, in this embodiment, the baffle 1 further includes a cantilever 14 extending in a front-back direction, the rear end of the cantilever 14 is fixedly connected to the bottom of the second flow guiding section 12, the cantilever 14 and the first flow guiding section 1113 are disposed at intervals in an up-down direction, and the clamping groove 1a is formed between the cantilever 14 and the first flow guiding section 1113. In this way, the front end of the cantilever 14 can warp and deform up and down, and a clamping space is formed between the front end and the first diversion section 1113. The length of the cantilever 14 in the front-rear direction may be equal to the length of the first deflector segment 1113 or may be slightly shorter than the length of the first deflector segment 1113 (see fig. 5). The length of the boom 14 may be set according to the specific model of vehicle.

Further, in this embodiment, the first flow guiding section 1113, the second flow guiding section 12, and the third flow guiding section are integrally formed with the cantilever 14. The material of the baffle 1 includes rubber or plastic, so that the baffle 1 may be formed into the first baffle segment 1113, the second baffle segment 12, the third baffle segment and the cantilever 14 by injection molding, etc., and the baffle 1 may have a certain toughness and elasticity when being matched with the engine cover 300, so that the baffle 1 may have a better holding force.

In this embodiment, referring to fig. 6, the height of the third flow guiding section in the up-down direction is H, where H is less than or equal to 50mm; and/or the length of the cantilever 14 in the front-rear direction is D, wherein D is more than or equal to 15mm and less than or equal to 25mm; and/or the thickness of the cantilever 14 in the up-down direction is W1, wherein W1 is 2 mm.ltoreq.W1 is 3mm.

It can be understood that the height of the third diversion section in the up-down direction is set to be less than or equal to 50mm, so that the lowest part of the visual field line of the driver can be not exceeded, and the driving safety is ensured. The thicknesses of the cantilever 14 and the first diversion section 1113 are set to be more than or equal to 2mm and less than or equal to 3mm, so that the strength of the cantilever 14 and the first diversion section 1113 is ensured. The length of the cantilever 14 in the front-rear direction is set to be 15mm or more and 25mm or less, so that the contact area between the cantilever 14 and the engine cover 300 is larger, and the mounting stability is ensured.

Further, since the airflow of the front windshield 200 is large during the running of the vehicle, particularly at high speed, and there is a certain reaction force on the third guiding section by the airflow, so that the guiding plate 1 is at risk of being separated from the engine cover 300, in this embodiment, the guiding structure 100 further includes a connection portion for fixedly connecting the guiding plate 1 to the engine cover 300. In this way, in addition to the baffle plate 1 being fixed to the engine cover 300 by the force of the engagement groove 1a, the baffle plate 1 may be connected to the engine cover 300 by the connection portion.

Specifically, in this embodiment, the baffle 1 is formed with a slot 1a with a slot opening facing forward, and the connection portion includes adhesive coated on an inner wall of the slot 1a. Thus, by applying the adhesive to the opposite surfaces of the cantilever 14 and the first deflector segment 1113, the deflector 1 can be adhered to the engine cover 300 in the form of adhesive.

The present invention further provides an automobile, which includes the above-mentioned flow guiding structure 100, and the automobile further includes an engine cover 300, and since the automobile includes the flow guiding structure 100, the specific structure of the flow guiding structure 100 refers to the above-mentioned embodiment, and since the flow guiding structure 100 of the automobile adopts all the technical solutions of all the above-mentioned embodiments, at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments are not described in detail herein.
