The electric device may be an electric device having the compressor 21, such as a dehumidifier, an outdoor unit of an air conditioner, a refrigerator, or the like.

During assembly, when the operator is twisting the locking member 33, the stop head 312 and the non-circular sub-aperture 10c are engaged to prevent the bolt member 31 from rotating with the locking member 33, so that the locking member 33 can be tightened. The interference fit between the rod 311 and the mounting sub-hole 10b can enable the bolt 31 to be tightly connected to the chassis 10 and not to easily fall off, that is, the compressor fixing structure of the embodiment of the present application can ensure that the locking member 33 can be locked to the bolt 31 and also ensure that the bolt 31 can be stably connected to the chassis 10, when the electrical equipment is violently shaken or falls off, the bolt 31 and/or the locking member 33 are not easily loosened, and the reliability is good, so that the compressor 21 can be relatively firmly fixed to the chassis 10 without shaking to a large extent, and further, the probability that the compressor 21 impacts the appearance and/or other internal components can be greatly reduced.

In the embodiment of the present application, the number of the leg plates 220 may be one or multiple, and the number of the fixing assemblies 30 needs to be adjusted according to the number of the leg plates 220, as long as each leg plate 220 can be connected to the corresponding fixing assembly 30.

The non-circular sub-hole 10c of the chassis 10 may be polygonal, semicircular, elliptical, irregular, etc. as long as the non-circular sub-hole 10c can prevent the stopper 312 from rotating.

In one embodiment, referring to fig. 1-8, the rod 311 includes a knurled section 311a, a polished rod section 311b, and a threaded section 311c, wherein the polished rod section 311b is located between the knurled section 311a and the threaded section 311 c; the knurled section 311a penetrates through the mounting sub-hole 10b and is in interference fit with the mounting sub-hole 10b, the buffering foot pad 32 is sleeved on the light rod section 311b, and the locking piece 33 is in threaded connection with the threaded section 311 c.

The knurled sections 311a of the bolt members 31 facilitate increasing the contact area and the friction between the bolt members 31 and the corresponding side walls of the mounting sub-holes 10b, so that the bolt members 31 can be connected with the base plate 10 more tightly, and the polished rod sections 311b can reduce the friction between the bolt members 31 and the buffering foot pads 32, so that the buffering foot pads 32 can buffer and absorb the shock of the compressor 21 by extending and contracting in the axial direction. In addition, the bolt piece 31 has a simple structure and is convenient to process, and the manufacturing cost of the bolt piece 31 can be saved while the reliability of the bolt piece 31 is improved.

In one embodiment, referring to fig. 2 to 7, a stepped hole 10a is formed through the bottom plate 10, and a bolt 31 is inserted into the stepped hole 10a from the bottom side of the bottom plate 10.

Specifically, the chassis 10 in the embodiment of the present application is an injection molded part, and there are various ways of assembling the bolt piece 31 to the chassis 10, for example, when the chassis 10 is not completely cooled after injection molding, the bolt piece 31 is pressed into the stepped hole 10a from the bottom side of the chassis 10 by using a tool, and after the chassis 10 is completely cooled, the mounting sub-hole 10b forms an interference tight fit with the knurled section 311a on the bolt piece 31 due to expansion and contraction of the chassis 10. For another example, after the bottom plate 10 is completely cooled, the bolt member 31 is heated, and then the heated bolt member 31 is pressed into the stepped hole 10a from the bottom side of the bottom plate 10 by using a tool, and after the bolt member 31 is completely cooled, the installation sub-hole 10b forms an interference tight fit with the knurled section 311a on the bolt member 31. Both of the above-described manners can facilitate the fitting of the bolt member 31.

In other embodiments, the chassis 10 may be injection molded onto the bolt members 31. Specifically, the knurled sections 311a of the bolt pieces 31 and the limiting heads 312 are embedded in the injection mold of the chassis 10, and after the chassis 10 is injection molded, the bolt pieces 31 and the chassis 10 are combined together.

In one embodiment, referring to fig. 3 and 9, the locking member 33 is spaced from the cushion pad 32 along the axial direction of the bolt member 31 so that the cushion pad 32 has a free movement stroke along the axial direction.

Specifically, when the electrical equipment is severely shaken or falls off, the buffering foot pad 32 can move axially on the polished rod section 311b of the bolt piece 31, and the foot supporting plate 220 sleeved on the buffering foot pad 32 can move together with the buffering foot pad 32 under the driving of the buffering foot pad 32, so that the buffering and shock-absorbing effects of the buffering foot pad 32 can be improved.

That is, the locking member 33 can limit the movement of the cushion pad 32 by means of the washer 332, so as to limit the movement of the cushion pad 32 within a certain range.

In one embodiment, referring to fig. 3 and 9, the minimum distance H1 between the cushion pad 32 and the washer 332 along the axial direction of the bolt member 31 is 0.5mm to 3 mm. This size range both can make buffering callus on the sole 32 can play better buffering cushioning effect, can avoid again that buffering callus on the sole 32 too big along axial motion amplitude and lead to compressor 21's the range of rocking to increase.

It is understood that in other embodiments, the locking member 33 may have only the nut 331 and no washer 332, and the nut 331 may be spaced from the cushion pad 32 to limit the cushion pad 32 to a certain range of movement.

In other embodiments, the locking member 33 and the buffering foot pad 32 may not be spaced apart from each other, for example, the locking member 33 may contact the buffering foot pad 32, and the locking member 33 may also abut against the buffering foot pad 32.

The projected contour of the washer 332 in the plane perpendicular to the axial direction of the bolt member 31 is not limited as long as it can support the cushion pad 32 over a large area. For example, it may be circular, polygonal, elliptical, etc.

When the electrical equipment is shaken or dropped violently, the turned-over edge 332a can press the leg plate 220 to prevent the shaking amplitude of the compressor 21 from being too large, thereby further reducing the possibility that the compressor 21 collides with the external appearance member and/or other internal components.

In one embodiment, referring to fig. 9, the distance H2 between the bottom end surface of the flange 332a and the top end surface of the leg plate 220 is 0.5mm to 3mm, which can not only ensure the normal vibration amplitude of the compressor 21 and achieve a better buffering and damping effect, but also better protect the compressor 21 from abnormal vibration.

In an embodiment, referring to fig. 3 and 9, the nut 331 and the washer 332 are an integrated structure, that is, the nut 331 and the washer 332 are an integrated structure connected together, which not only can improve the assembly efficiency, but also can prevent the nut 331 and the washer 332 from rubbing against each other to generate abnormal sound when the electrical equipment is in operation.

The shape of the pad 332 may be circular, rectangular, polygonal, irregular, etc., without limitation.

In other embodiments, the nut 331 and the washer 332 may be a separate structure and fixedly connected together, for example, the nut 331 and the washer 332 may be connected together by welding or the like.

In one embodiment, referring to fig. 3 and 9, the buffering foot pad 32 has a first shaft hole 32a and a second shaft hole 32b which are communicated with each other, the first shaft hole 32a is located at the bottom side of the second shaft hole 32b, the diameter of the first shaft hole 32a is smaller than that of the second shaft hole 32b, and the polish rod segment 311b is inserted into the first shaft hole 32a and the second shaft hole 32 b.

Specifically, the buffering foot pad 32 is generally made of an elastic material, and specifications of the bolt member 31 may be different according to models of electrical devices, for example, the electrical device a needs to use the bolt member 31 having a polished rod section 311B with a diameter of 8mm, and the electrical device B needs to use the bolt member 31 having a polished rod section 311B with a diameter of 10mm, so that the aperture of the first shaft hole 32a may be set to be about 8mm, the aperture of the second shaft hole 32B may be set to be about 10mm, after the bolt member 31 having a polished rod section 311B with a diameter of 8mm is inserted into the first shaft hole 32a and the second shaft hole 32B, the first shaft hole 32a may be matched with the polished rod section 311B, after the bolt member 31 having a polished rod section 311B with a diameter of 10mm is inserted into the first shaft hole 32a and the second shaft hole 32B, the second shaft hole 32B may be matched with the polished rod section 311B, and at the buffering foot pad 32 may also enable the polished rod section 311B to be in interference fit with the first shaft hole 32a through elastic deformation, that is, the first shaft hole 32a and the second shaft hole 32b having different diameters may facilitate the engagement of the cushion pad 32 with the bolt members 31 having different diameters of the polished rod section 311b, whereby the versatility of the cushion pad 32 may be improved.
