Description

Active lower spoiler for commercial vehicle

Technical Field

The utility model belongs to the technical field of the commercial vehicle front end air inlet system technique and specifically relates to a commercial vehicle is with active spoiler down.

Background

When the commercial vehicle is driven, the surrounding air flow can generate relative movement with the vehicle, thereby causing the pneumatic action of the commercial vehicle. The aerodynamic action comprises aerodynamic resistance and aerodynamic lift, wherein the aerodynamic resistance can directly influence the running speed and the fuel economy of the commercial vehicle, and is usually solved by arranging an AGS (absorption glass) on a front mask at the present stage; the aerodynamic lift force can reduce the adhesive force of the commercial vehicle to the ground, and can also generate induced resistance, so that the driving safety of the vehicle is directly influenced, and the problem to be solved is solved.

Based on the analysis, the utility model provides an arrange initiative spoiler in commercial car driver's cabin below, bumper rear, the spoiler under the initiative promptly, it can come the developments based on vehicle operating condition to retract and stretch out. For example, at lower vehicle speeds, the under spoiler retracts to a stowed position generally flush with the commercial vehicle chassis to reduce fluid resistance. When the commercial vehicle reaches a higher speed (about 50 to 60 miles per hour), the spoiler automatically expands to the extended position, so that an air dam for blocking air flow is formed, air flow entering the bottom of the vehicle can be reduced to the greatest extent, and the situation that the ground grabbing force of the rear wheels is weakened to influence the driving safety of the vehicle due to excessive air flow at the bottom of the vehicle is avoided.

Disclosure of Invention

The utility model provides a spoiler under active for commercial vehicle realizes intelligence according to the driving state of commercial vehicle and stretches out and the withdrawal to reduce the safety influence that pneumatic lift caused the commercial vehicle under the high speed.

In order to solve the technical problem, the technical scheme of the utility model is that: the utility model provides a spoiler under active for commercial vehicle which characterized in that: the lifting mechanism can be fixed on a chassis of the commercial vehicle, the working end of the lifting mechanism is detachably connected with the lower spoiler body, and the traveling crane computer is used for controlling the lifting mechanism to drive the lower spoiler body to do lifting action; the lifting mechanism is an electric push rod, and a circuit of the electric push rod can be connected with a driving computer of the commercial vehicle.

The technical scheme is further limited, and the electric push rods are symmetrically arranged.

Further inject above-mentioned technical scheme, be equipped with the connecting seat on electric putter's the work end, it has a plurality of bolt holes to equally divide cloth on the connecting seat, and the connecting seat passes through the bolt and realizes detachable the connection with lower spoiler body.

The technical scheme is further improved, in the electric push rod, a magnetic ring is arranged in the push rod, a magnetic inductor is arranged on the shell, and the magnetic ring and the magnetic inductor are matched to detect whether the electric push rod works normally or not.

The technical scheme is further limited, the lower spoiler is composed of an inner metal grid and an outer plastic surface layer, and the thickness of the lower spoiler is 5-8 mm.

The technical scheme is further limited, the top surface of the lower spoiler body is provided with a shallow groove, the shallow groove is used for positioning a connecting seat on the electric push rod, and the connecting seat is flush with the top surface of the lower spoiler body.

Has the advantages that: the utility model discloses apply under the initiative vortex technique to commercial car for weaken the air lift effect in the driving process, ensure ride comfort and security that commercial car went, the arrangement of spoiler is comparatively common on the current commercial car, and the technical scheme of spoiler under the commercial car has not seen the use yet; the utility model discloses according to stretching out and returning back of spoiler under car state signal control electric putter realizes, the electric putter product is comparatively ripe and can realize that the high position adjusts wantonly, can directly purchase on market to spoiler manufacturing cycle under the commercial car shortens.

Detailed Description

As shown in fig. 1 and 2, an active under spoiler for a commercial vehicle includes a lifting mechanism 1 and an under spoiler body 2, wherein the lifting mechanism can be fixed on a chassis of the commercial vehicle, a working end of the lifting mechanism is detachably connected with the under spoiler body, and a traveling computer is used for controlling the lifting mechanism to drive the under spoiler body to perform lifting action; the lifting mechanism is an electric push rod, and a circuit of the electric push rod is connected with a traveling crane computer through an LIN (local interconnect network) line of the commercial vehicle;

as shown in fig. 1 and 2, the electric push rods 1 are symmetrically arranged, so that the stability of the lower spoiler body can be improved, and the driving safety is ensured;

as shown in fig. 1 and 2, a connecting seat 3 is arranged on the working end of the electric push rod 1, a plurality of bolt holes are uniformly distributed on the connecting seat, and the connecting seat is detachably connected with the lower spoiler body through bolts 4; therefore, the structure is convenient to process and manufacture, is beneficial to reducing the production cost and is also convenient for later maintenance;

as shown in fig. 3, in the electric push rod 1, a magnetic ring 11 is arranged in the push rod, and a magnetic inductor 12 is arranged on the shell and can be connected with a traveling computer of a commercial vehicle; the magnetic ring is matched with the magnetic inductor to detect whether the electric push rod works normally or not, so that the driving safety is ensured;

as shown in fig. 3, the lower spoiler is formed by an inner metal grid 21 and an outer plastic surface layer 22 into a whole, and the thickness of the lower spoiler is 5-8mm, so that the structure is beneficial to light weight, the production cost is reduced, and the service life is not influenced; the inner metal grating is connected with the connecting seat, so that the connection is firmer; the plastic surface layer is made of PP +30% GF material;
