Description
Technical field
The present invention relates to technical field of vehicle, in particular to a kind of engine protecting and motor vehicle.
Background technique
Engine protecting is the engine protective device that body design is determined according to various different automobile types, and design concept is primarily anti-
Only the stone impact of road surface protrusion and cause engine damage, followed by order to prevent in the process of moving soil and sewage intrusion
Enging cabin leads to engine failure.Existing engine protecting is easy to appear weak heat-dissipating, maintenance difficult and causes engine
The problem of bottom case damages.
Summary of the invention
The first purpose of this invention is to provide a kind of engine protecting, solves motor vehicle conventional engines backplate and radiate
The not strong problem of poor, not easy to repair and protectiveness.
Second object of the present invention is to provide a kind of motor vehicle, and it is high, easily to solve conventional motor vehicle engine failure rate
Damage the problem low with security performance.
The embodiment of the present invention is achieved in that
A kind of engine protecting, engine protecting include sequentially connected first backplate, the second backplate and lower backplate, and first
Backplate and the second backplate are configured to be mounted on engine radiator bottom, and the second backplate and lower backplate are detachably connected, the
One backplate has the first flow-guiding channel and heat release hole, and the first flow-guiding channel and the setting of heat release hole interval, the second backplate have second
Flow-guiding channel, the second flow-guiding channel are arranged in parallel with the first flow-guiding channel, and lower backplate is configured to be mounted on engine bottom, under
Backplate has the heat dissipation channel being arranged with engine tilts.
Inventor's discovery: although existing engine protecting prevents backing from causing to damage to engine sump to a certain extent
It is bad, but install backplate additional and the gas fluidity of entire engine nacelle is deteriorated, influence the heat dissipation of engine；On the other hand,
It installs backplate additional to be usually fixedly connected with engine sump, replacement not easy to disassemble also will affect the sinking of engine and cause safety
Accident.
For this purpose, inventor devises above-mentioned engine protecting, engine protecting includes sequentially connected first backplate, second
Backplate and lower backplate, wherein the second backplate and lower backplate are detachably connected, the first backplate and the second backplate are mounted on engine
Radiator bottom, lower backplate are mounted on engine bottom, and the first backplate has spaced first flow-guiding channel and heat release hole,
Second backplate have with the first flow-guiding channel the second flow-guiding channel disposed in parallel, lower backplate has to be arranged with engine tilts
Heat dissipation channel.
Specifically, the bottom of engine radiator will be mounted on after the first backplate and the connection of the second backplate, then by lower backplate
The bottom of engine is mounted on after connecting with the second backplate.When motor vehicle is in driving process, from engine below the gas that flows through
On the one hand stream is flowed upwardly toward the surrounding of engine body by the heat dissipation channel being obliquely installed, on the other hand by the second flow-guiding channel and
Above first flow-guiding channel pilot flow direction engine radiator, due to lower backplate and the detachably connected guarantee second of the second backplate
Backplate and lower backplate may be adjusted to suitable obliquity consequently facilitating the whole of thermal current circulates, while heat release hole is conducive to hot gas
The diffusion of stream is convenient for engine radiating to enhance the gas fluidity of engine nacelle.When shock accident occurs in motor vehicle
When engine sinks, since the lower backplate one end connecting with engine and the second backplate are detachably connected, which can quilt
Engine weight itself is destroyed, conducive to the quick sinking of engine.It is conveniently torn open in addition, lower backplate is detachably connected with the second backplate
Maintenance replacement is unloaded, lower backplate also has the work of the stone impact for preventing road surface protrusion and soil and sewage intrusion enging cabin
With.Engine protecting efficiently solves the problems, such as that motor vehicle conventional engines backplate weak heat-dissipating, not easy to repair and protectiveness be not strong.
