In a possible implementation manner of the first embodiment of the present application, the first fixing element 113 is located on the third corner 116 of the cover body 100; and/or the first fixing member 113 is located at a fourth corner point 117 of the cover body 100.

Through the above possible implementation manner of the first embodiment of the present application, as shown in fig. 3, the number of the first fixing elements 113 may be one, or may be two, when two first fixing elements 113 are provided, the first fixing elements 113 are respectively located at the third corner point 116 and the fourth corner point 117 of the cover plate body 100, and after the first fixing elements 113, the first positioning elements 112, and the first magnetic elements 111 are respectively connected with the second fixing elements 214, the second positioning elements 212, and the second magnetic elements 211 on the panel body, four corner points of the cover plate body 100 can be positioned and fixed, so that the stability of the cover plate body 100 on the panel enclosure frame 200 is improved.

In a possible implementation manner of the first embodiment of the present application, as shown in fig. 2 and fig. 3, the first fixing part 113 includes a buckle, and the second fixing part 214 includes a hook fixedly connected to the panel enclosure 200, and the buckle is fastened to the hook.

Through the above possible implementation manner of the first embodiment of the present application, the buckle has the slot 114, and after the hook is fastened to the buckle, the barb 215 on the hook is inserted into the slot 114 to hook the buckle, so as to limit the hook to be detached from the buckle. The mounting direction of the buckle and the hook is the same as the covering direction, so that the mounting directions of the first positioning element 112 and the second positioning element 212, the first magnetic element 111 and the second magnetic element 211, and the first fixing element 113 and the second fixing element 214 are the same, and as a whole, all the assembly work can be completed only by pressing the cover plate body 100 in the covering direction towards the direction close to the panel enclosure frame 200, so that the first positioning element 112 is inserted into the second positioning element 212, the first magnetic element 111 and the second magnetic element 211 are attracted, and the first fixing element 113 and the second fixing element 214 are fastened.

In a possible implementation manner of the first embodiment of the present application, as shown in fig. 3 and fig. 5, the first magnetic member 111 and the cover plate body 100 may be configured to be fixedly connected or detachably fixedly connected, when the first magnetic member 111 and the cover plate body 100 are configured to be detachably fixedly connected, for example, the first magnetic member 111 is configured to be a cylindrical pin structure, the cover plate body 100 is provided with a pin hole 118, the first magnetic member 111 can be inserted into the pin hole 118, and the first magnetic member 111 and the pin hole 118 are in interference fit and can be fixed to each other by means of friction resistance therebetween.

During installation, the first positioning part 112 and the second positioning part 212 are accurately positioned, the cover plate body 100 is attached to the panel enclosure frame 200, the pin holes 118 are aligned with the magnetic part installation holes 213, the installation without screws is realized, the cover plate body 100 only needs to be compressed on the panel enclosure frame 200, the buckle and the hook are buckled, and finally, the first magnetic part 111 only needs to be manually inserted into the magnetic part installation holes 213 to attract the first magnetic part 111 and the second magnetic part 211.

In the second embodiment of the present application, a motor cover plate is provided, as shown in fig. 3, including the first mounting structure 110 in the first embodiment of the present application.

The motor cover plate provided by the second embodiment of the application, set up in the second mounting structure 210 that first mounting structure 110 corresponds on panel encloses frame 200, only need to press apron body 100 towards the direction that is close to panel and encloses frame 200 along covering the direction in the installation, make first locating piece 112 peg graft with second locating piece 212, make first magnetic part 111 and second magnetic part 211 actuation, make first fixing piece 113 and second fixing piece 214 lock joint, accomplish all assembly work promptly, compared with the prior art, under the condition that installation accuracy and assembly steadiness are ensured, owing to need not use the screw to fasten, consequently, the work load is still less, the installation effectiveness is higher.

The "corner point" refers to an area near a corner of the motor cover plate, and may be a vertex of the corner, or a surface near the vertex of the corner (located on a side of the motor cover plate close to the panel enclosure 200 when the motor cover plate is installed).

Finally, it should be noted that: the above embodiments are only used for illustrating the technical solutions of the present application, and not for limiting the same; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present application.
