Description

Technical Field

[0001] The utility model relates to the technical field of automobile appearance, in particular to an automobile front decorative plate. Background Art

[0002] The front fascia of a car, also known as the front decorative panel or front face panel, is an external part covering the front end of the car, usually made of plastic or composite materials. It not only has an aesthetic effect, giving the car a unique appearance and brand image, but also plays an important role in terms of function.

[0003] The grille is part of the front fascia of a car. It is an important part that connects the hood, front bumper and left and right headlights. Its main function is ventilation and heat dissipation. The cooling water tank and air conditioning condenser are both heat dissipation components located behind the grille. The air passing through the grille can better dissipate heat. In addition, the grille can also protect the internal structure of the car body and prevent foreign objects from damaging the core parts of the car body while the car is driving.

[0004] In the prior art, the grille of the front fascia of a car usually does not have a buffer structure. When a low-speed collision occurs after a collision, the grille without a buffer cannot absorb and disperse the impact force, which may cause greater damage to the grille itself and its connected components such as the bumper and engine hood. Utility Model Content

[0005] The utility model aims to provide a front fascia of an automobile, which has the advantage of buffering the center grille of the front fascia of the automobile in the event of a collision, thereby solving the problem that in the event of a low-speed collision after a collision, the center grille without buffering cannot absorb and disperse the impact force, which may cause greater damage to the center grille itself and components connected thereto, such as the bumper and the engine hood.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a front trim panel of an automobile, comprising a center grid structure, a plurality of buffer mechanisms are fixedly installed on the rear side of the center grid structure, the center grid structure is fixedly installed on a vehicle frame through the plurality of buffer mechanisms, the buffer mechanisms comprise a buffer shell, a first buffer cover, a second buffer cover, and a conduit, the buffer shell is fixedly installed inside the first buffer cover and the second buffer cover, a buffer rod is movably installed inside the buffer shell, a piston is fixedly installed on one end of the buffer rod away from the center grid structure, a first liquid inlet hole is provided inside the second buffer cover, a second liquid inlet hole is provided inside the first buffer cover, a pump is fixedly installed on the top of the first buffer cover, the second liquid inlet hole is fixedly connected to one side of the pump through a conduit, the first liquid inlet hole is fixedly connected to one side of the pump through a conduit, and a buffer is arranged inside the buffer shell.

[0007] As a preferred automobile front trim panel of the utility model, a secondary buffer boss is fixedly installed on one end of the piston away from the buffer rod, a secondary buffer groove is opened inside the first buffer cover, the secondary buffer boss is movably installed inside the secondary buffer groove, and a plurality of guide grooves are opened on the surface of the secondary buffer groove.

[0008] As a preferred embodiment of the automobile front trim panel of the utility model, an adjusting screw is threadedly installed on one side of the guide groove.

[0009] As a preferred embodiment of the automobile front trim panel of the utility model, a sealing ring is fixedly installed inside the secondary buffer groove, and a plurality of sealing rings are fixedly installed on the outer wall of the piston.

[0010] As a preferred automobile front trim panel of the utility model, the bottoms of the first buffer cover and the second buffer cover are both fixedly mounted with second lugs, and one side of the pump is fixedly connected with a liquid storage tank.

[0011] As a preferred automobile front trim panel of the utility model, the center grid structure includes an outer frame, a plurality of air intake grilles are fixedly installed inside the outer frame, and a plurality of first lugs are fixedly installed on one side of the outer frame.

[0012] As a preferred embodiment of the automobile front fascia of the utility model, the edges of the outer frame and the air intake grille are both chamfered.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. In the event of a collision, the utility model pushes the piston toward the first buffer cover through the buffer rod. At this time, the buffer enters the side of the piston away from the first buffer cover through the second liquid inlet hole, the conduit, the pump, the first liquid inlet hole, and the second buffer cover. In this process, the force generated in the collision is converted into heat energy through the resistance and kinetic energy of the buffer flow, so as to absorb and mitigate the impact force. After the collision, the pump runs to make the buffer push the piston to move toward one side of the second buffer cover to complete the reset. The utility model has the advantage of buffering the front trim grille of the automobile in the event of a collision, and solves the problem that when there is a low-speed collision after a collision, the unbuffered grille cannot absorb and disperse the impact force, which may cause greater damage to the grille itself and the bumper, engine hood and other components connected thereto.

[0015] 2. During the collision process of the utility model, when the piston moves quickly at the end of the stroke, the secondary buffer protrusion is inserted into the secondary buffer groove to block the secondary buffer groove, and the buffer can only flow through the guide groove, so that the flow of the buffer is initially slowed down. When the secondary buffer protrusion is gradually displaced to one side of the guide groove, it will gradually block the liquid outlet of the guide groove, and finally stop the displacement of the buffer. By gradually increasing the flow resistance of the buffer, the piston speed can be steadily reduced when approaching the end point, thereby avoiding violent collision to damage the buffer mechanism body.

[0022] When a collision occurs, the grille structure 1 pushes the piston 203 to move toward the first buffer cover 204 through the buffer rod 202. At this time, the buffer enters the side of the piston 203 away from the first buffer cover 204 through the second liquid inlet hole 207, the conduit 208, the pump 209, the first liquid inlet hole 206, and the second buffer cover 205. In this process, the force generated in the collision is converted into heat energy through the resistance and kinetic energy of the buffer flow, thereby absorbing and mitigating the impact force. When the collision is over, the pump 209 runs to make the buffer push the piston 203 to move to one side of the second buffer cover 205 to complete the reset. It has the advantage of buffering the grille of the front trim panel of the car when a collision occurs, and solves the problem that when there is a low-speed collision after a collision, the grille without buffer cannot absorb and disperse the impact force, which may cause greater damage to the grille itself and the bumper, engine hood and other components connected to it.

When the secondary buffer protrusion 210 gradually moves to one side of the guide groove 212, it will gradually block the liquid outlet of the guide groove 212, and finally stop the displacement of the buffer solution. By gradually increasing the flow resistance of the buffer solution, the speed of the piston 203 can be steadily reduced when approaching the end point, thereby avoiding violent collision and damaging the buffer mechanism 2 body.
