Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and embodiments.

First, the terms of orientation "inside" and "outside" related to the present embodiment will be described, in which the direction close to the center inside the electronic control box is "inside" and the direction away from the center inside the electronic control box is "outside" in the present embodiment.

Referring to fig. 1 to 3, an electronic control box 1 of the present embodiment is a sheet metal box, and includes a back panel 10, a maintenance area 11, a plurality of disassembly operation areas 12, and a plurality of mounting posts 13; the maintenance area 11 is formed on the rear back plate 10 by punching outwards, and the rear back plate 10 can be detached; the plurality of disassembling operation areas 12 are used for operating the disassembling maintenance areas 11, the number of the disassembling maintenance areas is not less than 3, the disassembling maintenance areas 11 are punched inwards, and the disassembling operation areas 12 are not positioned on the same straight line and form a polygonal figure in a surrounding mode; and a plurality of mounting posts 13 for mounting the disassembled maintenance area 12 on the backboard 10, wherein the mounting posts 13 are formed on the backboard 10, the number of the mounting posts is the same as that of the disassembling operation areas 12, and the shape of a figure (a figure surrounded by dotted lines in fig. 1) surrounded by the plurality of mounting posts 13 is the same as that of a figure (a figure surrounded by dotted lines in fig. 1) surrounded by the plurality of disassembling operation areas 12, and is partially overlapped.

Specifically, in the electrical control box 1 of the present embodiment, since it is a sheet metal box, and the maintenance area 11 and the detachment operation area 12 are both formed by stamping, if an electrical device near the rear side inside the box is to be maintained, a tool such as a screwdriver can be used to knock off the plurality of detachment operation areas 12, a detachment hole 14 is formed on the maintenance area 11, and then the screwdrivers penetrate into the detachment holes 14 one by one, or the screwdrivers penetrate into the detachment holes 14 simultaneously to tilt up the whole maintenance area 11 plate so as to separate from the backboard 10, as shown in fig. 2, correspondingly, a maintenance hole 15 having a shape adapted to the maintenance area 11 is formed on the backboard 10, so that the electrical device near the rear side inside the electrical control box can be maintained conveniently through the maintenance hole 15; after the maintenance is finished, the maintenance area 11 can be remounted on the back panel 10 by matching the mounting posts 13 with the dismounting holes 14 to shield a part of the maintenance hole 15, so as to ensure the use safety and play a certain waterproof and shielding function.

Further, each side of the figure surrounded by the mounting posts 13 and each side of the figure surrounded by the dismounting operation areas 14 are in one-to-one correspondence and parallel arrangement, so that the maintenance area 11 can be conveniently and realigned and mounted on the backboard 10 after being dismounted.

The top edge a of the figure (figure 1 enclosed by the dashed and dotted lines) enclosed by the mounting posts 13 is located below the top edge B of the figure (figure 1 enclosed by the dashed and dotted lines) enclosed by the dismounting operation areas 14, that is, after the maintenance is completed, the position of the remounted maintenance area 11 is lower than the original position, which is more in line with the operation habit.

Further, since the pattern shape defined by the plurality of mounting posts 13 partially overlaps the pattern shape defined by the plurality of disassembling operation areas 12, the repairing area 11 only covers a part of the repairing hole 15 after being remounted, and the other part C is exposed, and the part C can be used as a heat dissipation hole to dissipate heat of the electronic control box body, and then the exposed part C exists, so that the risk of mistakenly extending a hand is present, in order to avoid the problem as much as possible, a sawtooth part 16 is formed on the top edge of the repairing area 11, accordingly, when the repairing area 11 is tilted away from the back panel 10, the top edge of the repairing hole 15 is in a sawtooth shape, as shown in fig. 2, after the repairing area 11 is remounted on the back panel 10, the sawtooth-shaped top edge of the repairing hole 15 is located on the exposed part C, as shown in fig. 3, so as to avoid direct exposure, and the sawtooth-shaped structure is favorable for increasing the. The tooth shape of the serration 16 may be triangular, rectangular, T-shaped, etc., which is T-shaped in the present embodiment.

For the convenience of punch forming, the dismounting operation area 12 is circular, correspondingly, the formed dismounting hole 14 is a circular hole, the mounting column 13 is a threaded rivet with a diameter smaller than that of the dismounting operation area 12, after the maintenance area 11 is dismounted, the mounting column 13 can be sleeved with the dismounting hole 14, and then the maintenance area 11 is fixed through a nut 17, as shown in fig. 3 and 4, so that the sealing protection performance of the electric control box body 1 and the maintenance area 11 which can be dismounted repeatedly in the later period are ensured to carry out maintenance or replacement of electric devices in the box body.

The repair area 11 is of the simplest triangular shape to facilitate the stamping process, and preferably has an outward stamping projection depth of 0.1-0.2 mm.

The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or that equivalents may be substituted for elements thereof; such modifications and substitutions do not depart from the spirit and scope of the present invention, which is claimed.
