and an initial tail 3 connected to the extension assembly for guiding the flow of the airflow and bearing the pressure of the airflow.
In one case of the embodiment, by arranging the extension assembly connected with the initial tail wing 3, when the automobile runs, airflow flowing through the automobile body impacts the extension assembly, the extension assembly pushes the initial tail wing 3 to move, the hidden plate 2 is exposed and forms a new tail wing with a larger area with the initial tail wing 3, as the speed of the automobile increases, the flow velocity of the airflow increases, the extension assembly drives the initial tail wing 3 to increase in displacement, so that the area of the new tail wing increases as the speed of the automobile increases, the grasping capacity of the automobile is improved by the tail wing with the increased area, and when the speed is lower, the friction between the automobile and the ground is less, so that fuel is saved; when the speed of a motor vehicle reaches a certain degree, the extension component drives the fixed rotating component to start displacement, the fixed rotating component pushes the initial tail wing 3 to rotate, and at the moment, the initial tail wing 3 rotates while moving horizontally, so that the included angle between the initial tail wing 3 and the airflow is increased, the airflow pressure borne by the initial tail wing 3 is increased, and the ground grabbing capacity and the stability of the motor vehicle are further improved. The problem that the effect of the fixedly installed tail wing on the automobile can only be positive within a certain speed range, and when the speed of the automobile exceeds or is lower than the speed range, the effect of the tail wing is weakened or negative influence is caused is solved.
In one aspect of this embodiment, two sets of extension assemblies and two sets of top rotation assemblies are symmetrically disposed on two sides of the mounting base 1, and a hidden plate 2 mounted on the mounting base 1 is disposed between two initial tail fins 3 in the two sets of extension assemblies. Let extension subassembly and decide the equal symmetry setting of subassembly, be in order to guarantee that car both sides atress can be balanced, and when the car turned, the air current that the car both sides received strikes differently, both sides extension subassembly and decide the subassembly and be different to the promotion effect of initial fin 3, make the pressure that leans on inboard initial fin 3 to receive great, the ability of grabbing of the inboard tire of car is stronger, avoid the car to skid when the turn, the security increases.
As shown in fig. 1 and 2, in one embodiment, the expansion component includes:
the shell 6 is connected with the mounting seat 1;
a baffle 7 installed inside the case 6 for dividing an inner space of the case 6; a gap is reserved between one end of the guide plate 7, close to the mounting seat 1, and the shell 6, the other end of the guide plate is fixed with the shell 6, and an opening communicated with the outside is formed between the other end of the guide plate 7 and the shell 6;
one end of the support part 4 is arranged in the shell 6 in a sliding and sealing mode, and the other end of the support part penetrates through the shell 6 to be connected with the initial tail wing 3 and is used for driving the initial tail wing 3 to move;
and the two ends of the elastic part 8 are respectively connected with the supporting part 4 and one end of the shell 6 close to the mounting seat 1 and used for drawing the supporting part 4 back to the initial position.
When the airflow enters the shell 6 from the opening continuously, the airflow is guided by the guide plate 7 and impacts the support part 4 continuously, so that the support part 4 moves towards two sides to drive the initial tail wing 3 to move towards two sides, the hidden plate 2 positioned below the initial tail wing 3 is exposed at the moment to form a new tail wing with the initial tail wing 3, the area of the tail wing is increased, and the pressure is increased. When the vehicle speed is low, the airflow is not enough to push the support piece 4 to move, so that the pressure of the airflow on the automobile is mainly generated by the pressure generated by the initial tail wing 3 when the vehicle speed is low, the pressure is low, and the fuel is saved. When the automobile stops running, the airflow impact is reduced along with the reduction of the speed of the automobile, and the support piece 4 resets under the pulling of the elastic piece 8 to drive the initial tail wing 3 to return to the initial position. The extension component can also be a component such as an air cylinder or an oil cylinder which can push the initial tail wing 3 to move. The elastic member 8 may be a spring, and may also be replaced by other elastic members, such as a silica gel column, an elastic sheet, and the like, which is not specifically limited in this embodiment.
In order to ensure that the supporting piece 4 always keeps the sealing performance of the shell 6 in the moving process, telescopic pieces 9 are arranged between the two sides of the supporting piece 4 and the shell 6. The telescopic member 9 may be a corrugated plate, a rubber member with elasticity, or a multi-stage nested telescopic assembly, etc., as long as the support member 4 can maintain the sealing performance of the housing 6 during the movement.
In addition, said support 4 is provided with at least one secondary support 19, each of said secondary supports 19 being associated with the initial tail 3. The addition of the secondary support 19 can increase the stability of the initial rear wing 3 so that the initial rear wing 3 is less vibrated during the movement of the vehicle.
In a preferred embodiment, as shown in fig. 2 and 3, the top rotating assembly comprises:
a guide cover 10 mounted on the housing 6 and communicating with the inside of the housing 6;
a piston 11 slidably and hermetically installed in the guide cover 10 for dividing the guide cover 10 and sealing the guide cover 10;
one end of the ejector rod 12 is mounted on the piston 11, and the other end penetrates the guide cover 10.
When the support member 4 is continuously moved to both sides, the support member 4 compresses the air between the support member 4 and the piston 11, so that the piston 11 moves upwards, and since the ram 12 is spaced from the initial tail fin 3, the ram 12 has no influence on the initial tail fin 3 within a certain distance from the support member 4 and the piston 11, that is, the jacking assembly does not work within a certain speed range. After the top bar 12 contacts the initial tail 3, the support 4 pushes the piston 11 and the top bar 12 to move, and the top bar 12 pushes the initial tail 3 to rotate. When the vehicle speed drops, the initial tail fin 3 falls back under the action of gravity. In addition, under the condition of not considering linkage, the jacking component can also be a telescopic component such as an oil cylinder or an air cylinder.
As shown in fig. 2 and 3, in a preferred embodiment, the mount 1 is provided with a guide 5, the guide 5 is disposed between the initial tail 3 and the guide cover 10, the support 4 and the lift pin 12 penetrate the guide 5, the support 4 moves in the guide 5 in vertical and horizontal directions, and the lift pin 12 moves in the guide 5 in vertical direction. The guide part 5 is added to further strengthen the stability of the expansion assembly and the jacking assembly and prevent the support part 4 and the ejector rod 12 from shaking in the process of moving the automobile.
In one aspect of the present embodiment, as shown in fig. 2-4, a reset member 13 is disposed between the initial tail 3 and the guide 5, and one end of the reset member 13 is fixedly mounted on the guide 5, and the other end is slidably mounted on the initial tail 3. The restoring member 13 is added to enhance the ability of the initial rear wing 3 to restore and enable the initial rear wing 3 to fall back immediately after the vehicle speed has dropped. The reset element 13 may be a spring, and may also be replaced by other elastic elements, such as a silica gel column, an elastic sheet, etc., which is not specifically limited in this embodiment.
In addition, the other end of the reset piece 13 is fixedly provided with a slide block 14, and the slide block 14 is slidably clamped in a slide rail 15 on the initial tail wing 3. The sliding block 14 and the sliding rail 15 are added to ensure that the reset piece 13 is not deformed, and prolong the service life of the reset piece 13.
As shown in fig. 1 and 5, in another preferred embodiment, a wind-collecting cover 16 is installed at an opening formed between the other end of the flow guide plate 7 and the housing 6, at least one air hole 17 is formed in the wind-collecting cover 16, and an induced draft plate 18 is installed on the wind-collecting cover 16. The wind-collecting cover 16 is added to increase the sensitivity of the whole adjusting mechanism to the change of the air flow, so that more air flow enters the wind-collecting cover 16 through the air holes 17 under the guidance of the air-inducing plate 18 and further enters the shell 6. And the diameter size of the air hole 17 can also be changed according to the demand, the size of the air hole 17 can be changed, and the sensitivity of the adjusting mechanism can also be changed.
