Description
Technical Field
The invention relates to the field of automobile exterior trim, in particular to a movement mechanism for an active front lip.
Background
Along with the landing of energy saving and emission reduction policies, the requirements of vehicles on oil consumption are higher and higher. In order to reduce oil consumption, besides improving oil proportion and reducing the weight of the whole vehicle, a main engine factory considers that the front lip form is changed to improve the aerodynamic state of the whole vehicle, namely, the air vortex is reduced by reducing the air quantity flowing through the bottom of the vehicle, and the purposes of reducing wind resistance, saving fuel, saving energy and reducing emission are achieved by means of computer simulation and education.
The front lip of the whole vehicle on the market is fixed at present, as shown in fig. 1, because of the trafficability requirement of the whole vehicle, the Z-direction size of the front lip of the middle part is smaller, otherwise, the front lip is easy to collide with road obstacles. The size of the front lip is limited, so that the wind resistance reducing function of the front lip cannot meet the design requirement, and the aerodynamic performance of the whole vehicle is limited.
Aiming at the defects of the fixed front lip, the inventor develops an active front lip, but the active front lip is limited by the movement track of the active front lip and cannot meet the requirements of the trafficability and aerodynamic performance of the whole vehicle.

Detailed Description
The invention will be further described with reference to the accompanying drawings and examples which are to be understood as illustrative only and not limiting.
The active front lip is added on the basis of the fixed front lip, so that the Z-direction dimension of the middle part of the vehicle, which is lost due to the passing requirement of the whole vehicle, is compensated. As shown in fig. 2 (a), the active front lip 16 is recessed in the X-direction into the rear of the fixed front lip 15 and is exposed to the lower portion of the bumper skin 14.
The movement mechanism for the active front lip provided by the invention is shown in fig. 2 (b), and the movement mechanism 18 is connected with the lower leg protection beam 12 of the whole vehicle and is reversely arranged on the active front lip 16 along the direction X.
The explosion diagram of the moving mechanism and the active front lip assembly of the invention is shown in fig. 3, and the moving mechanism 18 comprises a motor 1, a framework 2, a side mounting plate 7 and a transmission mechanism 19. Wherein, the two ends of the framework 2 are pivoted with a transmission mechanism 19 and are provided with side mounting plates 7, and the middle part of the framework 2 is provided with a motor 1.
The transmission mechanism 19 comprises a driving shaft 4, a connecting rod 6, a first swing arm 20 and a second swing arm 21. As shown in fig. 4, the drive shaft 4 is mounted on the side mounting plate 7 at one end and connected to the motor 1 at the other end. The driving shaft 4 is pivoted with the first swing arm 20, and the first swing arm 20 is fixedly connected with the connecting rod 6. The connecting rod 6 is further fixedly connected with a second swing arm 21, and the second swing arm 21 is pivoted on the side mounting plate 7, so that the second swing arm 21 can rotate around the pivot 5.
As shown in fig. 5, which is a schematic diagram of the driving shaft structure, one end connected to the motor 1 is a motor torque input end 40, one end fixedly connected to the first connecting device is a torque output end 41, and the middle is a torque transmission rod 42. The design scheme can be divided into two types:
Firstly, a split type structure is adopted, a motor torque input end 40 and a torque output end 41 adopt a plastic injection molding method, and a torque transmission rod 42 adopts a metal rod, so that the loss during torque transmission can be reduced to the greatest extent;
second, the motor torque input 40 and torque output 41 are maintained in unison with the split structure using an integral structure, i.e., an integral injection molding, and the torque transfer rod 42 uses a reinforced structure to reduce torque loss due to the reduction of torsion generated by the rod itself.
The active front lip 16 includes an active front lip fascia 8, an active front lip backplate 11, and a mounting bracket 10. The active front lip decorative plate 8 is attached to the active front lip back plate 11 or is adhered together through a 3M adhesive tape, the mounting bracket 10 is mounted on the active front lip back plate 11, and the mounting bracket 10 is connected with the connecting rod 6.
The movement mechanism 18 with the components mounted is mounted on the mounting sheet metal 9, and the mounting sheet metal 9 is welded on the shank protective beam 12.
In the present embodiment, the motor 1 is provided with a motor protection cover 3, and both ends of the installation frame 2 are provided with mechanism protection covers 13.
After the installation, the motion mechanism 18 of the present invention needs to be debugged, and the position and the length of the torque transmission rod 42 are debugged to change the active front lip motion track, and the position and the length of the torque transmission rod 42 are finally determined by assisting in computer simulation so as to maximize the active front lip function.
The principle that the driving shaft 4 drives the driving front lip 16 to move is that the driving shaft 4 outputs torque to rotate, meanwhile, the first swing arm 20 and the second swing arm 21 are driven to rotate, and the connecting rod 6 moves according to a designed movement track under the combined action of the driving shaft 4 and the swing arms, so that the driving front lip 16 is driven to move obliquely in the Z direction and the X direction. When the automobile normally runs, the active front lip moves to a forward extending state, and the height of the automobile chassis is reduced at the moment, so that the air inlet quantity entering the automobile chassis is reduced, the down force of the automobile is increased, the wind resistance is reduced, and the aerodynamic performance of the whole automobile is improved. When an obstacle or a road is rugged, the active front lip moves to a retracted state, and the height of the automobile chassis is increased at the moment, so that the automobile can smoothly pass.
Further, in view of the appearance and sealing requirements, the present embodiment designs a convex hull 23 on the active front lip trim 8, as shown in fig. 6, so that the active front lip 16 and the fixed front lip 15 do zero clearance fit. The design can effectively relieve the deformation of the fixed front lip 15 under high-speed wind pressure, and enhance the tightness between the active front lip 16 and the fixed front lip 15, so that the whole vehicle achieves the expected aerodynamic performance.
The invention can also change the mode of the cooperation use of the active front lip and the fixed front lip into the full-active front lip, and the full-active front lip can be designed to increase the trafficability of the whole vehicle on the premise of ensuring the improvement of the aerodynamics of the whole vehicle.
The foregoing description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and various modifications can be made to the above-described embodiment of the present invention. All simple, equivalent changes and modifications made in accordance with the claims and the specification of this application fall within the scope of the patent claims. The present invention is not described in detail in the conventional art.
