The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

As shown in fig. 1 to 5, the utility model discloses a front panel 10 of air conditioner shell, include: a front panel 1, a first fold 2 and a second fold 3. The upper edge of the front panel 1 forms a first folded edge 2 and a second folded edge 3, and the cross sections of the two folded edges are distributed in a mirror image of L shape, so that the structural strength of the front panel 10 of the outdoor unit is further enhanced. In addition, through setting up first hem 2 and second hem 3 on front panel 10, can be with air condensing units's motor support 60 connect with the second hem 3 on, can bear the motor on the motor support 60, the motor, the vibrations of motor support 60 can transmit to the second hem 3 on, and be connected by first hem 2 between second hem 3 and the front bezel 1, consequently, can reduce the vibrations that transmit on the front bezel 1 effectively, and, through setting up first hem 2 and second hem 3, can improve the structural strength of front panel 10, and then also can reduce the vibrations of front panel 10.

In addition, the first folding edge 2 and the second folding edge 3 are arranged in the application, so that the contact area between the motor support 60 of the outdoor fan 70 and the front panel 10 can be reduced compared with the traditional overlapping mode, the vibration of the front panel 10 can be further weakened, and the noise can be reduced.

Meanwhile, in the embodiment shown in fig. 1 and 4, the air conditioner front panel 10 includes the front panel 1, the first flange 2 and the second flange 3 which are integrally stamped, but in other embodiments, the three structures may be any other reasonable structures, such as welding, riveting, pinning, screwing or bolting, etc.

Preferably, in the embodiment shown in fig. 1, the front panel 10 has a plate shape made of 53-gauge steel. The steel No. 53 has a higher carbon content and a higher hardness than the conventionally used steel No. 54. Of course, in other embodiments, the selection of the steel material may be based on actual needs, and is not limited specifically herein. According to the attribute of panel and structure, on the basis of guaranteeing front panel 10 structural stability, can reduce the width of first hem 2 (first hem 2 also can be called as the support step here), be favorable to attenuate the fuselage, practice thrift installation space, improve outward appearance aesthetic measure.

In addition, to facilitate the thinning of the body and to secure the structural stability of the front panel 10, the width dimension of the first folded edge 2 in the front-rear direction may preferably be in the range of 15 mm to 20 mm. Depending on the material of the steel plate and its own hardness, this range may be reasonably preferred, for example, the range may be reduced to a width of less than 15 mm. Or to increase the space of the outdoor unit, the range can be increased moderately to make the width dimension larger than 20 mm.

Further, as shown in fig. 4, the second flange 3 is provided with a boss portion 31 projecting forward of the front surface of the second flange 3. One purpose of the bosses is to increase the strength of the structure. Meanwhile, another purpose of providing the boss is to reduce noise, for example, at both sides of the boss portion 31 or the boss in the left-right direction, screw holes are provided to fix the motor bracket 60 of the outdoor fan 70 system, and the space of the boss can effectively block the transmission of noise, thereby achieving the effect of vibration reduction and noise reduction. Of course, the pattern of the projections may be varied, for example, as shown in fig. 1 and 5, the projections are spaced apart in the left-right direction at the second flange 3. In other embodiments, the bosses may be designed as one or more bosses continuously distributed in the left-right direction, one or more bosses extending in the up-down direction at the second folded edge 3, one or more bosses spaced apart in the up-down direction at the second edge, one or more bosses arranged in an intersecting manner, and the like.

In addition, since the front panel 10 needs to be assembled with the top cover 40 to complete the assembly of the outdoor unit casing, at least one side edge of the top cover 40 of the outdoor unit casing is installed at the outer edge of the second flange 3 of the front panel 10, and the distance between the front surface of the second flange 3 and the front surface of the front panel 1 needs to be greater than the protruding height of the boss part 31 with respect to the second flange 3 in consideration of installation size, because when the protruding height of the boss part 31 is greater than the distance between the front surface of the second flange 3 and the front surface of the front panel 1, the boss will be pushed against the top cover 40 of the air conditioner, and the installation of the top cover 40 of the air conditioner is not facilitated on the premise that no space is reserved at the position of the boss of the top cover 40 with respect to the second flange 3.

Preferably, the ratio of the distance between the front surface of the second flange 3 and the front surface of the front panel 1 to the projection height of the boss portion 31 may be set in the range of 1:1 to 5: 1. Tests show that when the ratio of the distance between the front surface of the second flange 3 and the front surface of the front plate 1 to the projection height of the boss portion 31 is within this range, the structural stability is facilitated, and the phenomenon of excessive stress concentration is not easily caused when the top plate is bent and deformed, such as when the top plate is stepped on and suddenly pressed down. Of course, when the boss structure, the arrangement mode, the sheet metal material and the like are changed, the ratio of the distance between the front surface of the second flange 3 and the front surface of the front plate 1 to the projection height of the boss portion 31 may be less than 5:1, but not more than 1: 1.

Therefore, the motor bracket 60 is required to form an inward groove at the butt joint part where the positioning flange 32 extends backward, or a through hole 36 penetrating through the side wall of the motor bracket 60, so that the positioning flange 32 is inserted into the groove or the through hole 36 to form a preliminary pre-positioning. Therefore, the installation range of the fastening member can be rapidly positioned during installation, the motor bracket 60 and the front panel 10 are prevented from easily shifting during installation, the motor bracket 60 needs to be adjusted again, and the assembly efficiency of the motor bracket 60 of the outdoor unit can be improved regardless of the conventional manual assembly or the automatic machine assembly.

The pre-positioning of the motor bracket 60 and the second flange 3 may also be other connection manners, for example, a forward boss or through hole 36 is formed at the second flange 3, a forward snap or a folded edge is formed at the butt joint position of the motor bracket 60, and the snap or the folded edge extends forward into the boss or the through hole 36 on the second flange 3 of the front panel 10, so as to primarily position the motor bracket 60, but here, it should be noted that the forward protruding boss of the second flange 3 cannot affect the installation of the top cover 40 of the outdoor unit, in other words, the protruding height of the boss may not exceed the height from the second folded edge 3 to the front surface of the front panel 10, or the height of the folded edge formed on the motor bracket 60 may not be greater than the height from the second folded edge 3 to the front surface of the front panel 10. In addition, the specific structure of the positioning flange 32 is not limited, and may be, for example, a single-layer flange, a multi-layer flange, or other reasonable flange shapes.

As shown in fig. 1 and 2, the motor bracket 60 has a mounting hole 33 formed through the second flange 3 adjacent to the positioning flange 32. The fastening member is fastened to the motor bracket 60 through the mounting hole 33 of the motor bracket 60, such as a screw or bolt connection, a rivet or pin connection, or the like. And the fastener can be exposed on the front surface of the second flange 3 after being connected, and can also be sunk into the front surface of the second flange 3.

For example, in the embodiment shown in fig. 1 and 3, the second flange 3 is provided with a sinking platform structure 35 recessed backward, and the bottom wall of the sinking platform structure 35 is provided with a through hole 36; due to the structural design, the fastener connected with the motor bracket 60 can sink into the front surface of the second flange 3, so that the appearance is more attractive and elegant.
