Abstract
A lower protection panel for vehicle engines: The utility model relates to a vehicle engine accessory to resolve the following problems in vehicle services: The chassis is easy to be damaged; the air flow below the chassis might bring forth wind sound and noise; engine radiation effect is no good because of flashed mud and sludge. The utility model provides a lower protection panel for vehicle engines; the lower protection panel is a board-shaped structure; the overall appearance match the shape of the chassis below the vehicle engine; the protection panel is provided with mounting screw holes, access holes, air inlet holes and reinforced ribs; the bottom surface of the air hole takes the shape of a triangular slope; the length of the air hole slope is between 125 mm and 175 mm; the opening width of the air hole is between 130 mm and 170 mm; the height of the air hole is between 10 mm and 40 mm. This structure of the lower protection panel for engines can effectively protect the chassis; the design of the bottom surface can make the air flow stably go through the chassis without resistance when the vehicle is running; meanwhile, the noise is rather low, so that the air holes can cool the engine with air flow.
Description
Technical field
The utility model relates to a kind of automotive engine accessory.
Background technology
Because automotive engine is positioned on the chassis, when automobile when rough and uneven in surface or heavy road face travel, ground-surface jut or bulk stone collides the chassis easily, damage engine or part on every side cause mortal injury to automobile; Simultaneously, automobile travels on the heavy road face, and a large amount of earth can splash, sticky on driving engine, influences engine radiating; In addition, automobile is when running at high speed, and air-flow forms vortex under car chassis, car is advanced cause obstruction on the one hand, causes bigger noise on the other hand, influences passenger and chaufeur mood.For addressing these problems, people are at automobile lower, design and installation time backplate, backplate respectively has characteristics under the existing automobile, effect has nothing in common with each other, and is unsatisfactory to the solution of the problems referred to above.
The utility model content
For solving the easy damaged in chassis in the running car, wind sound that the chassis downstream is brought and noise and the earth bad problem of engine radiating of splashing, the utility model provides a kind of car engine lower guard board, following backplate is tabular, shape is square, the middle part is curved to recessed, square front end the circular arc lines excision that concaved by two symmetrically of two angles, the chassis shape of whole profile and vehicle motor below matches, the installation screw at two ends is corresponding with the installation screw on the chassis before and after on the backplate, backplate is provided with service hatch and fresh air inlet and vertical reinforced rib of arranging, opening direction is over against headstock the place ahead of automobile, inclined-plane triangular in shape, the bottom surface in wind hole, protrude to the backplate lower end, air port inclined plane length is between 125 millimeters to 175 millimeters, wind hole A/F is between 130 millimeters to 170 millimeters, and the height of wind hole opening is between 10 millimeters to 40 millimeters, and this is corresponding for the discharge side of the position of service hatch and the gear oil of automobile engine lubricating oil.
Wind hole on the following backplate is no less than one at least.
Reinforced rib on the following backplate, width are between 10 to 40 millimeters, and the degree of depth is between 1 millimeter to 6 millimeters.
The radical of the reinforced rib on the following backplate is no less than two at least.
The engine lower guard board of said structure can effectively be protected the chassis, avoids ground-surface jut or bulk stone collision chassis, and the damage auto parts and components avoid earth to splash on the driving engine, influence engine radiating; Bottom surface design makes that the air-flow under the chassis can steadily flow through in the running car, can not form resistance, and noise is also very little; Wind hole and mainboard face gradient and wind hole opening yardstick can make on the backplate air-flow orientation of flowing through down and blow, and from fast, steadily passing through between backplate and the tray bottom down, thereby play the effect of cooled engine.
Description of drawings
Fig. 1 is the utility model scheme drawing.
The specific embodiment
Car engine lower guard board as shown in Figure 1, following backplate 1 is tabular, shape is square, the middle part is curved to recessed, square front end two angles cut symmetrically, tangent line is two circular arc lines that concave, the chassis shape of the profile of whole backplate and vehicle motor below matches, the installation screw 2 at two ends is corresponding with the installation screw on the chassis before and after on the backplate 1, and backplate is provided with service hatch 3 and wind hole 5 and vertical reinforced rib of arranging 4, and reinforced rib 4 has four, its width is 20 millimeters, the degree of depth is that 4 millimeters wind holes 5 have two, and inclined-plane triangular in shape, its bottom surface protrudes to backplate 1 below, opening direction is over against headstock the place ahead of automobile, wind hole 5 chamfer lengths are 150 millimeters, and wind hole opening 6 width are 140 millimeters, and the height of wind hole opening 6 is 20 millimeters; This is corresponding for the discharge side of the position of service hatch and the gear oil of automobile engine lubricating oil, has two.
