Abstract
The invention relates to a part of an automotive alternator, and in particular relates to an automotive alternator protective cover. The automotive alternator protective cover comprises a cover body and an air vent which is formed on the cover body, wherein the inner side of the bottom surface of the cover body is provided with a plurality of locking bosses used for fixing; the ends of the locking bosses are in an arc shape; the diameter of the ends of the locking bosses is greater than the diameters of other parts of the locking bosses; and the diameter of the locking bosses is matched with the diameter of a through hole on an alternator rear cover. Compared with the background art, the automotive alternator protective cover has the advantages of fewer parts, fewer machining processes, convenience in assembly and stability and reliability in assembly, so that the automotive alternator protective cover has a good protective effect.
Description
Technical field
The present invention relates to a kind of parts of automobile current generator, particularly relate to a kind of automotive alternator protective cover.
Background technology
Protective cover is an important assembly in AC generator for vehicle, and the form of protective cover is varied, but fixed form leans on screw fastening substantially.Current known patent publication number CN3010902826, title " generator protective cover ", it has a housing, wherein this housing has 2 fixing holes and 10 ventilation holes, this generator protective cover is connected with generator by screw by 2 fixing holes, although this kind of protective cover also can effectively be fixed on generator, play the effect of protective power generation machine, but its weak point existed is: not only increase the small part such as screw and pad, need to arrange screwed hole on protective cover, increase manufacturing procedure, need to tighten screw in installation process simultaneously, make the loaded down with trivial details inefficiency of its assembly process, and be threaded in long-time vibrations process easily make its loosen.
Summary of the invention
The present invention, in order to the defect that solves above-mentioned prior art and exist and deficiency, provides that a kind of part is few, manufacturing procedure is few, simultaneously easy to assembly, and solid and reliable, thus the automotive alternator protective cover that protection effect is good.
Technical scheme of the present invention: a kind of automotive alternator protective cover, comprise cover body and be arranged on the ventilation hole on cover body, be provided with some for fixing locking boss inside described cover body bottom surface, the end of described locking boss is arc-shaped, and the end diameter of locking boss is greater than the diameter of locking boss other parts, the diameter compatible of through hole on the diameter of described locking boss and generator rear cover.
Preferably, described locking boss end is provided with opening, and described opening is connected with locking boss elasticity.
Preferably, the quantity of described locking boss is three, and is triangular in shapely distributed on cover body bottom surface.
Preferably, described locking boss bottom is provided with stay, and described locking boss is fixed on cover body bottom surface by stay.
Preferably, described ventilation hole is evenly distributed on cover body bottom surface.
Preferably, described three locking boss surroundings are equipped with some reinforcements.
Preferably, described opening is arranged on locking boss upper side, and the shape of through holes on open front shape and generator rear cover matches.
Preferably, the installing hole for installing is provided with in the middle part of described cover body bottom surface.
The present invention is by arranging three locking boss and the through hole interference fit on generator rear cover, and the opening that can produce micro-strain is set in boss upper side, thus ensure that locking boss can enter bonnet through hole smoothly, make it with hand, protective cover bonnet through hole of beating in can be reached the object of clamping when assembling, thus solve the problem that protective cover assembly process is loaded down with trivial details before this, greatly improve efficiency of assembling.
The present invention compared with background technology, 1. part few (reduce screw material consumption); 2. manufacturing procedure few (not needing to arrange screwed hole on cover body); 3. (saving the assembly process tightening screw with instrument) easy to assembly; 4. assembling solid and reliable (due to be locking boss coordinate with bonnet through hole is enjoyable after again by the structure that opening clamps, the probability that can reduce is threaded loosens because of vibrations).
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the partial sectional view of A-A in Fig. 1.
1. cover bodies, 2. ventilation hole in figure, 3. lock boss, 4. opening, 5. stay, 6. reinforcement, 7. installing hole.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further detailed explanation, but be not limiting the scope of the invention.
As shown in Figure 1-2, a kind of automotive alternator protective cover, comprises cover body 1 and is evenly distributed on ventilation hole 2 on cover body 1 bottom surface, is provided with three for fixing locking boss 3 inside cover body 1 bottom surface, and convex 3 of three locking is triangular in shapely distributed on cover body 1 bottom surface.The end of locking boss 3 be arc-shaped, and the end diameter of locking boss 3 is greater than the diameter of locking boss 3 other parts, locks the diameter compatible of through hole on the diameter of boss 3 and generator rear cover.Locking boss 3 upper side is provided with opening 4, opening 4 with lock boss 3 elasticity and be connected, and the shape of through holes on opening 4 front end geometry and generator rear cover matches.Be provided with stay 5 bottom locking boss 3, locking boss 3 is fixed on cover body 1 bottom surface by stay 5.Three locking boss 3 surroundings are equipped with some reinforcements 6.The installing hole 7 for installing is provided with in the middle part of cover body 1 bottom surface.
The present invention is by arranging three locking boss and the through hole interference fit on generator rear cover, and the opening that can produce micro-strain is set in boss upper side, thus ensure that locking boss can enter bonnet through hole smoothly, make it with hand, protective cover bonnet through hole of beating in can be reached the object of clamping when assembling, thus solve the problem that protective cover assembly process is loaded down with trivial details before this, greatly improve efficiency of assembling.
The present invention compared with background technology, 1. part few (reduce screw material consumption); 2. manufacturing procedure few (not needing to arrange screwed hole on cover body); 3. (saving the assembly process tightening screw with instrument) easy to assembly; 4. assembling solid and reliable (due to be locking boss coordinate with bonnet through hole is enjoyable after again by the structure that opening clamps, the probability that can reduce is threaded loosens because of vibrations).
