Description

Technical Field

[0001] The utility model relates to the technical field of racing car front wings, in particular to a FSAE racing car front wing main wing skeleton. Background Art

[0002] In the world of FSAE (Formula SAE, or Formula Student Racing) racing, optimizing car performance is a constant theme. The front wing, a crucial component of a car's aerodynamics package, has a crucial impact on its handling, stability, and speed.

[0003] The front wing consists of a main wing structure and a number of additional components. The horizontal flaps at the front are called the main wing, while the angled flaps above and behind them are called flaps or ailerons. Most racing cars choose to install flaps on the outside of the span, thus achieving greater downforce through the long-chord straight main wing.

[0004] However, the wind resistance of the front wing of this design is relatively large, and the load on the outer side of the main wing is relatively large, resulting in large deformation of the front wing when the vehicle body is excited by the road at high speed. The lift and drag of the front wing are relatively low, and the general front wing cannot play a guiding role, and cannot increase the efficiency of the aerodynamic kit behind it. In addition, the current technology used to delay flow separation is to place a baffle-type vortex generator in the normal direction of the important aerodynamic surface, using its sharp edge to induce vortexes, thereby delaying flow separation. However, existing vortex generators used in racing cars cannot accurately induce vortices upstream of the wing's stall point, increasing the car's frontal area and drag.

[0005] Therefore, it is necessary to design a FSAE racing car front wing main wing skeleton with high spoiler effect, small frontal area and resistance to solve the above problems. Utility Model Content

[0006] The utility model provides a FSAE racing car front wing main wing frame, which solves the above-mentioned technical problems.

[0007] To solve the above technical problems, the present invention provides a FSAE racing car front wing main wing frame, comprising a main wing frame body and a racing car front. Support plates are fixed on both sides of the middle portion of the main wing frame body, and the racing car front is fixedly connected between the two support plates. A main spoiler structure is fixed to the rear of the main wing frame body near both sides of the racing car front, and a secondary spoiler structure is fixed to the front of the main spoiler structure. Pressure retaining strips are fixed to both side ends of the main wing frame body, and a vortex generating structure is fixed to the top of the pressure retaining strips.

[0008] Preferably, the main spoiler structure includes three fixing plates fixed to the top rear of the main wing frame body, and the three fixing plates are divided into two spoiler areas. One spoiler area has two outer flaps installed in an upper and lower staggered manner, and the other spoiler area has three inner flaps installed in an upper and lower staggered manner.

[0009] Preferably, the two outer flaps form an outer composite wing, and an outer channel is formed between the two outer flaps.

[0010] Preferably, the three inner flaps form an inner synthetic wing, and two upper and lower inner channels are formed between the three inner flaps.

[0011] Preferably, the secondary spoiler structure includes an arc-shaped spoiler provided on the main wing frame body and two connecting plates fixed to the top front portion of the main wing frame body, and small flaps are fixed between the two connecting plates in an upper and lower staggered manner.

[0012] Preferably, the two small flaps form an outer composite wing, and the lower small flap is inclined outward to form a diversion channel with the upper small flap.

[0013] Preferably, the vortex generating structure includes a primary vortex generator fixed on the front of the racing car, and a secondary vortex generator is fixed on the top front side of the primary vortex generator. The primary vortex generator is a pentahedral structure, and the secondary vortex generator is teardrop-shaped.

[0014] Compared with related technologies, the FSAE racing car front wing main wing frame provided by the present invention has the following beneficial effects:

[0015] The utility model provides a main wing frame body that is installed at the front of a racing car through two support plates. A main spoiler structure, a secondary spoiler structure, and a vortex generating structure are symmetrically installed on the main wing frame body, which can significantly increase the downforce of the racing car, enhance the grip of the tires, and thus improve the handling performance and stability of the racing car.

[0021] Embodiment 1, by Figure 1-4 A FSAE racing car front wing main wing frame is provided, comprising a main wing frame body 1 and a racing car head 2, support plates 3 are fixed on both sides of the middle part of the main wing frame body 1, and the racing car head 2 is fixedly connected between the two support plates 3, a main spoiler structure 4 is fixed to the rear part of the main wing frame body 1 near both sides of the racing car head 2, and a secondary spoiler structure 5 is fixed to the front part near the main spoiler structure 4, pressure maintaining strips 6 are fixed to both side ends of the main wing frame body 1, and a vortex generating structure 7 is fixed to the top of the pressure maintaining strip 6.

[0022] Specifically, the main wing frame body 1 is installed at the front 2 of the racing car through two support plates 3. The main spoiler structure 4, the secondary spoiler structure 5 and the vortex generating structure 7 are symmetrically installed on the main wing frame body 1, which can significantly increase the downforce of the racing car and enhance the grip of the tires, thereby improving the handling performance and stability of the racing car. Through the carefully arranged airflow channels and diversion channels, the airflow can be effectively managed, the impact of turbulence generated by the rotation of the front wheels on the performance of the racing car can be reduced, and the aerodynamic efficiency of the racing car can be improved.

[0023] In this embodiment, the main spoiler structure 4 includes three fixed plates 41 fixed to the top and rear part of the main wing frame body 1. The three fixed plates 41 are divided into two spoiler areas. One spoiler area is staggered with two outer flaps 42 installed up and down, and the other spoiler area is staggered with three inner flaps 43 installed up and down. The two outer flaps 42 form an outer synthetic wing, and an outer channel is formed between the two outer flaps 42. The three inner flaps 43 form an inner synthetic wing, and two upper and lower inner channels are formed between the three inner flaps 43.

[0024] Specifically, the main spoiler structure 4 is divided into two spoiler areas, one spoiler area is installed with two outer flaps 42 staggered up and down, and the other spoiler area is installed with three inner flaps 43 staggered up and down. The aerodynamic layout of the combination of the main wing frame body 1, the outer flaps 42 and the inner flaps 43 has a better spoiler effect, which can make the horizontal incoming flow converge toward the central axis of the vehicle body after passing through the front wing and enter the diffuser inlet located in the middle of the vehicle body, thereby increasing the efficiency of the diffuser. At the same time, such a design will allow part of the airflow to bypass the rolling wheels, greatly reducing the lift of the rolling wheels caused by the Magnus effect and the resistance caused by the high relative speed between the rolling wheels and the incoming flow.

[0025] Example 2, based on Example 1, the secondary spoiler structure 5 includes an arc-shaped spoiler 51 arranged on the main wing frame body 1 and two connecting plates 52 fixed to the top front part of the main wing frame body 1, and small flaps 53 are fixed alternately between the two connecting plates 52. The two small flaps 53 form an outer synthetic wing, and the lower small flap 53 is inclined outward to form a diversion channel with the upper small flap 53.

[0026] Specifically, the secondary spoiler structure 5 comprises a curved spoiler 51 mounted on the main wing frame 1 and two connecting plates 52 with small flaps 53 interlaced between them. The curved spoiler 51 and the interlaced small flaps 53 combine to form a diversion channel. This design further optimizes airflow and improves the aerodynamic efficiency of the canard. The lower small flaps 53 are tilted outward, forming a diversion channel with the upper small flaps 53, helping to guide airflow, reduce drag, and increase downforce.

[0027] In the third embodiment, based on the first embodiment, the vortex generating structure 7 includes a first-stage vortex generator 71 fixed on the front of the racing car 2, and a second-stage vortex generator 72 is fixed on the top front side of the first-stage vortex generator 71. The first-stage vortex generator 71 is a pentahedral structure, and the second-stage vortex generator 72 is teardrop-shaped.

[0028] Specifically, referring to the vortex generator based on the FSAE racing car with publication number CN213620003U, a vortex generating structure 7 is installed on the edges of both sides of the main wing frame body 1, and a structure combining a first-stage vortex generator 71 and a second-stage vortex generator 72 is adopted. The first-stage vortex generator 71 adopts a double-edge and wedge-shaped structure design, and the front windward surface and the tail of the vortex generator both adopt a sharp edge structure, which can simultaneously induce two vortices with opposite rotation directions in the negative direction of the vehicle body coordinate system X, with high induction efficiency. At the same time, the second-stage vortex generator 72 can reduce the flow separation of the airflow in the vortex generator plane and help to improve the strength of the vortex induced by the vortex generator body.

[0029] Working principle:

[0030] The main wing frame body 1 is mounted on the front 2 of the racing car via two support plates 3. The main spoiler structure 4, the secondary spoiler structure 5 and the vortex generating structure 7 are symmetrically mounted on the main wing frame body 1, which can significantly increase the downforce of the racing car and enhance the grip of the tires, thereby improving the handling performance and stability of the racing car. Through the carefully arranged airflow channels and diversion channels, the airflow can be effectively managed, reducing the impact of turbulence generated by the rotation of the front wheels on the performance of the racing car, and improving the aerodynamic efficiency of the racing car.

[0031] The secondary spoiler structure 5 comprises a curved spoiler 51 mounted on the main wing frame 1 and two connecting plates 52 with interlaced flaps 53 fixed between them. The curved spoiler 51 and the interlaced flaps 53 form a diversion channel. This design further optimizes airflow and improves the aerodynamic efficiency of the canard. The lower flaps 53 are tilted outward, forming a diversion channel with the upper flaps 53, helping to guide airflow, reduce drag, and increase downforce.

[0032] The main spoiler structure 4 is divided into two spoiler areas. Two outer flaps 42 are installed in a vertically staggered manner in one spoiler area, and three inner flaps 43 are installed in a vertically staggered manner in the other spoiler area. The aerodynamic layout of the main wing frame body 1, the outer flaps 42 and the inner flaps 43 has a better spoiler effect. It can make the horizontal incoming flow converge toward the center axis of the vehicle body after passing through the front wing and enter the diffuser inlet located in the middle of the vehicle body, thereby increasing the efficiency of the diffuser. At the same time, this design allows part of the airflow to bypass the rolling wheels, greatly reducing the lift of the rolling wheels caused by the Magnus effect and the resistance caused by the high relative speed between the rolling wheels and the incoming flow.

[0033] The vortex generating structure 7 is installed on the edges of both sides of the main wing frame body 1, and adopts a structure combining a first-stage vortex generator 71 and a second-stage vortex generator 72. The first-stage vortex generator 71 adopts a double-edge and wedge-shaped structure design, and the front windward surface and the tail of the vortex generator both adopt a sharp edge structure, which can simultaneously induce two vortices with opposite rotation directions in the negative direction of the vehicle body coordinate system X, with high induction efficiency. At the same time, the second-stage vortex generator 72 can reduce the flow separation of the airflow in the vortex generator plane, and help to improve the strength of the vortex induced by the vortex generator body.
