Description

Protective cover

Technical Field

The utility model relates to an automobile power generation machine field especially relates to a protective cover.

Background

With the development of society and the continuous progress of science and technology, the power of the automobile generator is larger and larger, and with the more and more rigorous requirements on environmental protection and energy conservation, the automobile generator tends to be miniaturized and developed with high power. In the field of commercial vehicles and engineering vehicles, an original single outer fan generator is gradually eliminated due to the large power and small volume, a double inner fan generator gradually goes to a stage, but the double inner fan generator adopts a heat dissipation mode of axial air inlet and radial air outlet of an end cover, so that the working environment of the commercial vehicles and the engineering vehicles is harsh, the air channel is easily blocked, and the design of a protective cover is a key influencing the air channel. Some manufacturers adopt a mode of adding sieve holes on the end cover, and because the die-casting process is limited, the end cover with the aperture smaller than 6mm cannot be cast out, and impurities can enter the motor to block the air duct; some manufacturers adopt a steel wire mesh mode, fix the steel wire mesh by rivets, and are inconvenient to assemble and inconvenient to clean.

Therefore, there is a need for a protective cover that is both easy to install and easy to clean.

The utility model provides a protective cover, including the circular shape apron of demountable installation on the generator end cover, the through-hole has been seted up to the centre of apron, be provided with a plurality of sieve meshes on the apron, the symmetry is provided with four group's buckles on the apron, just two bisymmetry distributions of four group's buckles are in on four directions of apron, the apron passes through the buckle is installed on the generator end cover, the aperture of sieve mesh is 2 mm.

In some embodiments of the present invention, four avoiding holes are formed in the outer side of the cover plate corresponding to the positions of the buckles.

In some embodiments of the present invention, the cover plate and the buckle are made by an injection molding process.

In some embodiments of the present invention, the buckle includes two buckle bodies with the buckle teeth oppositely arranged, the width of the buckle teeth is 2mm, and the height of the buckle body is 8 mm.

In some embodiments of the present invention, the edge of the through hole is further provided with an interference fit rib.

Compared with the prior art, the utility model discloses there is following advantage:

the embodiment of the utility model provides a protective cover passes through injection molding process one shot forming, and production convenient and fast can not need screw or fix with rivet and direct mount on generator end cover through setting up the buckle, when needs are cleared up, through buckling thereby elastic buckle can be dismantled fast, is convenient for carry out the dismouting clearance, and overall structure is simple reliable, and is with low costs, and the protecting effect is good.

Detailed Description

In order to make the technical field person understand the scheme of the present invention better, the following will combine the drawings in the embodiments of the present invention to clearly and completely describe the technical scheme in the embodiments of the present invention. It is to be understood that the embodiments described are merely exemplary of the invention, and that no limitations are intended to the details of construction or design herein shown. The present invention may be embodied in many different forms and is not limited to the embodiments described herein, which are provided for the purpose of providing a more thorough understanding of the present disclosure.

Refer to and show in figure 1, the protective cover includes demountable installation and laps 1 at the circular shape on the generator end cover, through-hole 4 has been seted up to the centre of apron 1, through-hole 4 is used for dodging the bearing that extends on the generator end cover, be provided with a plurality of sieve meshes 2 on the apron 1, the symmetry is provided with four group's buckles 3 on the apron 1, just 3 two bisymmetry distributions of four group's buckles are in on four directions of apron 1, apron 1 passes through buckle 3 is installed on the generator end cover, the aperture of sieve mesh 2 is 2mm, can effectively block debris, avoids getting into the generator and blocks up the wind channel.

Four avoidance holes 6 are formed in the outer side of the cover plate 1 corresponding to the positions of the buckles 3 and used for providing avoidance space for installation screw holes in the end cover of the generator.

The cover plate 1 and the buckle 3 are manufactured by an injection molding integrated forming process, are formed in one step, and are convenient and fast to produce.

As shown in fig. 2, the buckle 3 includes two buckle bodies 30 with opposite buckle teeth, the buckle bodies 30 are elastic components, the width of the buckle teeth is 2mm, the height of the buckle bodies 30 is 8mm, and when the buckle 3 is inserted into the generator end cover, the buckle teeth are clamped in the mounting holes at corresponding positions on the generator end cover by bending the buckle bodies 30, so that the cover plate 1 and the generator end cover are relatively fixed.

Certainly, it should be noted that, in some application scenarios, in order to further enhance the installation stability of the cover plate 1 and the generator end cover, an interference fit rib 5 is further convexly provided at the edge of the through hole 4, and the middle area of the cover plate 1 is installed in an interference fit manner with the generator end cover through the interference fit rib 5.

The embodiment of the utility model provides a protective cover passes through injection molding process one shot forming, and production convenient and fast can not need screw or fix with rivet and direct mount on generator end cover through setting up buckle 3, when needs are cleared up, through buckling elastic buckle 3 can dismantle fast, is convenient for carry out the dismouting clearance, and overall structure is simple reliable, and is with low costs, and the protecting effect is good.

Those not described in detail in this specification are within the skill of the art.
