Specific embodiment
It is carried out below with reference to technical effect of the embodiment and attached drawing to the design of the utility model, specific structure and generation
Clear, complete description, to be completely understood by the purpose of this utility model, scheme and effect.It should be noted that not conflicting
In the case where, the features in the embodiments and the embodiments of the present application can be combined with each other.
It should be noted that unless otherwise specified, when a certain feature referred to as " fixation ", " connection " are in another feature,
It can directly fix, be connected to another feature, and can also fix, be connected to another feature indirectly.In addition, this
The descriptions such as upper and lower, left and right used in utility model are only the phase relative to each component part of the utility model in attached drawing
For mutual positional relationship.
In addition, unless otherwise defined, the technology of all technical and scientific terms used herein and the art
The normally understood meaning of personnel is identical.Term used in the description is intended merely to description specific embodiment herein, without
It is to limit the utility model.Term " and or " used herein includes appointing for one or more relevant listed items
The combination of meaning.
Fig. 1 is the structural schematic diagram of one embodiment of the utility model, and cover plate 1 includes cover board body 2, for enhancing
The structural strength of cover board 1 is internally provided with latticed reinforcing rib 3 in cover board body 2.Wherein, latticed reinforcing rib 3 is by multiple groups
Grid reinforcing rib unit composition, grid reinforcing rib unit are provided with the item along 2 length direction of cover board body and width direction extension
Shape reinforcing rib 4, the strip reinforcing rib 4 have been encircled into multiple grid reinforcing rib units.As shown in Fig. 2, in the present embodiment,
On each section of strip reinforcing rib 4 of rebar element surrounding, one is respectively arranged with along 2 length direction of cover board body and width direction
A curved portion 5 to arch upward along 2 thickness direction of cover board body to cover board body.
It in other embodiments, can also be only in the strip reinforcing rib 4 of rebar element surrounding along the length side of cover board body 2
To or width direction be arranged curved portion 5.In addition, by adjusting the quantity and distribution of rebar element, it can be in rebar element 4 four
Multiple arcs portion 5 is set on each section of strip reinforcing rib 4 in week, similarly difference can also be respectively set on different extending directions
The curved portion 5 of quantity, or various sizes of curved portion 5 is set on different extending directions.
In use, the cover board 1 of curved portion 5 is provided with when being under pressure, since curved portion 5 is partial dome structure,
Therefore, the power being subject to can be transmitted to adjacent part when compression, with the latticed reinforcing rib of conventional strip for being not provided with curved portion 5
It compares, bigger pressure can be born by resisting the power that curved portion both ends are distributed.It can be seen that the motor control in the application
Water channel cover board 1 compared with prior art, has better structural strength, and when compression is less also easy to produce deformation.
It as in Figure 3-5, is the latticed reinforcing rib water channel cover board of conventional strip before the improvement of 6mm thickness by 0.2MPa
Pressure condition under equivalent strain figure, equivalent stress figure and total deformation figure.Wherein as seen from the figure, such conventional strip is latticed
The maximum Equivalent Elastic Strain (equivalent strain) of reinforcing rib water channel cover board is 0.0027855m/m,
Equivalent Stress (equivalent stress) is 1.92575e8Pa, and Total Deformation (total deformation) is
0.00023029m.And correspondingly, as shown in figs 6-8, for be similarly 6mm it is thick using the improved band arc in the present embodiment
The strip grid reinforcing rib water channel cover board in shape portion by under 0.2MPa pressure condition equivalent strain figure, equivalent stress figure and
Total deformation figure.Wherein as seen from the figure, accordingly based upon strip of the use with curved portion described in the embodiments of the present invention
Latticed reinforcing rib water channel cover board Equivalent Elastic Strain (equivalent strain) is 0.0018631m/m,
Equivalent Stress (equivalent stress) is 1.292e8Pa, and Total Deformation (total deformation) is 0.0001345m.
It follows that improved cover board possesses smaller strain, smaller equivalent stress and smaller under same stress condition
Total deformation, that is, under same stress condition, improved cover board is less susceptible to occur compared with the conventional cover plate before improvement
Deformation has better structural strength.
In use, as shown in Fig. 1,2 and 9, electric machine controller water channel cover board 1 is mounted on external box of microvave 6, can also covered
Multiple mounting holes are arranged in the edge of plate ontology 2, for the connection with external box of microvave 6.Use the motor control of the cover board 1 in the application
Device processed, when being pressurized, compared with prior art, is not likely to produce deformation, and then reduce since cover board 1 has more preferable structural strength
Gap between external box of microvave so that coolant liquid therein flows in the diversion trench of setting, and is avoided since gap is excessive
Lead to coolant liquid random flowing in gap, ensure that the effect to cool.
Therefore, cover board can also be reduced in practice based on higher structural strength to a certain extent as the case may be
1 thickness, and then material is saved, reduce cost.Meanwhile the molding of aluminium die-casting process can also be used when manufacture, effectively further
The structural strength of cover board 1 is improved, while reducing thickness and weight.In other embodiments, cover board is also by other metal material systems
At.
It is to be illustrated to the preferable implementation of the utility model, but the invention is not limited to the reality above
Example is applied, those skilled in the art can also make various equivalent variations without departing from the spirit of the present invention
Or replacement, these equivalent deformations or replacement are all included in the scope defined by the claims of the present application.
