As shown, the plurality of mounting portions 11 are sequentially spaced along the peripheral edge of the cover plate, and it should be understood that the peripheral edge of the cover plate has a shape substantially identical to the corresponding structure of the box body, and the specific shape is not the core invention point of the present application, and does not substantially limit the claimed cover plate.
In the present embodiment, four sets of the first rib net 30 are provided on the inner surface of the cover plate body 20, and here, the first rib net 30 is disposed inside the peripheral edge 10 adjacent to the partial mounting portion 11; in other words, the first stiffener mesh group 30 is mainly disposed corresponding to the connection portion of the cover plate and the box body, so as to improve the restraining rigidity of the controller cover plate and enhance the bearing capacity of a relatively large load position.
As shown, four first sets of web of reinforcing bars 30 are arranged in pairs in vertically and horizontally opposed relationship. Here, the lateral and longitudinal directions are defined with reference to the cover plate in the orientation shown in fig. 2 as a description reference, and it is understood that the use of the above-described orientation words is only used to describe the relative positional relationship between the constituent parts of the present embodiment.
In addition, in other specific applications, the configuration is not limited to the four sets shown in the figure, and the configuration may be specifically determined as multiple sets according to the overall setting requirement of the actual product, and at least some sets of the multiple sets of the first reinforcing rib mesh sets 30 are configured to be arranged in a vertically and horizontally opposite manner. In addition, a one-to-many or many-to-many opposing arrangement may be employed in the transverse or longitudinal direction.
Wherein, first strengthening rib net group 30 includes profile strengthening rib 31 and inside strengthening rib 32, and profile strengthening rib 31 closes with the periphery 10 of apron and forms the reinforced area, and inside strengthening rib 32 sets up and is connected in this reinforced area and with profile strengthening rib 31. The first set of reinforcing bars 30, which can be locally reinforced, is formed as a whole. Further, the inner reinforcing rib 32 is provided in plurality, and the plurality of inner reinforcing ribs 32 are provided in parallel.

So set up, except great installation load position department, form the inside additional strengthening of integration through second strengthening rib net group 40, can increase the bearing capacity of each first strengthening rib net group 30, and both cooperate jointly and can further strengthen the bulk rigidity of controller apron.
Wherein the second set of reinforcing bars 40 comprises a plurality of second reinforcing bars 41. As shown, a second transverse reinforcing rib 41 is connected between the two first transversely opposite reinforcing rib net sets 30, and is connected with the two outer profile reinforcing ribs 31. Two second reinforcing bars 41 arranged longitudinally are connected between two first reinforcing bar network groups 30 arranged longitudinally opposite and are also connected to both profile reinforcing bars 31 respectively.
In this embodiment, the peripheral edge 10 of the cover plate includes a plurality of straight line segments, wherein the lengths of the segments a, B, C and D are longer, and correspondingly, the four first reinforcing rib net sets 30 are respectively disposed inside the four segments of the peripheral edge 10. Specifically, it is preferable to dispose the first net group of reinforcing beads 30 adjacent to the mounting portion 11 on the straight line section having a longer preset length in order to maximize the rigidity of the corresponding region.
It should be noted that, in the engineering implementation, for example, but not limited to, the specific configuration form of the reinforcing rib is determined by using topology optimization and professional finite element simulation software, so that the experience trial and error cost can be reduced, the product quality is greatly reduced, and the structural rigidity is improved.
Compared with a modal cloud chart formed by the traditional typical cover plate structure in the background technology, the first-order constraint mode of the modal cloud chart is 770.4Hz, and the mass of the cover plate is 1.15Kg; in the embodiment, the mode cloud chart formed by the cover plate structure of the topology optimization structure shown in fig. 1 has the first-order constraint mode of 1023.6Hz and the cover plate mass of 1.03Kg.
