When the outdoor unit of the air conditioner is transported, the outdoor unit of the air conditioner needs to be fixed on a chassis assembly of the air conditioner. The size of the base plate assembly often directly determines the packing size of the outdoor unit of the air conditioner. Because the whole weight of the air conditioner outdoor unit is larger, the bottom feet are arranged on the base plate assembly for fixing, and the base plate assembly plays a role in bearing and supporting the air conditioner outdoor unit. In the prior art, the bottom feet of the air conditioner outdoor unit have many problems. First, in order to fix the outdoor unit of the air conditioner or other components, the bottom feet of the outdoor unit of the air conditioner are provided with fixing holes. The fixing holes of the feet are usually exposed from the edge of the sidewall of the outdoor unit of the air conditioner, which results in an increase in the width dimension of the entire base plate assembly. Therefore, the overall packaging size is increased and the cabinet loading amount is reduced during transportation of the air conditioner outdoor unit. Secondly, during the transportation process of the outdoor unit of the air conditioner or the process of falling off due to improper operation, the feet are easy to bend and deform due to the larger weight of the outdoor unit of the air conditioner. Furthermore, the chassis assemblies of the prior art are provided with a plurality of feet, which are often arranged two by two. And two by two are connected together by the fixed section to increase its support intensity. However, with such a design, feet with different width sizes need to be manufactured separately for air conditioner outdoor units with different width sizes. That is, in the prior art, the chassis assembly of the air conditioner outdoor unit has a problem that the chassis assembly cannot adapt to air conditioner outdoor units with different widths. Therefore, it is necessary to improve the supporting strength, structural strength, etc. of the footing and the chassis on which the footing is mounted, by making a special structural design.

Referring to fig. 1 and 2, the present invention provides a base plate assembly 100 of an outdoor unit of an air conditioner, the base plate assembly 100 of the outdoor unit of the air conditioner includes a base plate 20 and at least 3 feet 10, at least 3 mounting grooves are formed on a bottom surface of the base plate 20, and the mounting grooves are formed by recessing a side wall of the base plate 20 toward the inside of the base plate 20; at least 3 footing 10 corresponds respectively and sets up in at least 3 the mounting groove, every footing 10 includes supporting part 11 and fixed part 12, supporting part 11 connects the bottom surface of chassis 20, fixed part 12 by supporting part 11 side orientation 20 lateral wall depressed part of chassis extends and forms, fixed part 12 is provided with fixed orifices 121, and at least part fixed orifices 121 follow 20 lateral wall depressed part of chassis exposes.

The foot 10 according to the present invention can be extended into the mounting groove more than the conventional foot 10, and the width of the chassis assembly can be further reduced. The supporting part 11 is disposed on the bottom surface of the chassis 20, and is connected to the bottom surface of the chassis 20 for supporting. In an alternative embodiment, the fixing portion 12 extends entirely out of the recess of the side wall of the chassis 20. In an alternative embodiment, the fixing portion 12 extends only partially out of the recess in the sidewall of the base plate 20. In this case, the fixing holes 121 provided in the fixing portion 12 may be entirely exposed from the recess of the side wall of the chassis 20, or partially exposed from the recess of the side wall of the chassis 20. The fixing holes 121 are used for fixing the air conditioner outdoor unit to the ground or other supporting surface by passing through fixing members, so as to improve the firmness and stability of the air conditioner outdoor unit or other workpieces fixed on the chassis assembly. In an alternative embodiment, only a portion of the fixing portion 12 is exposed from the recess of the sidewall of the bottom plate 20, and only a portion of the fixing hole 121 is exposed from the recess of the sidewall of the bottom plate 20. With this arrangement, since a portion of the fixing hole 121 is exposed from the recess of the side wall of the chassis 20, the chassis assembly can be assembled through the exposed portion of the fixing hole 121. Also, in this embodiment, the foot 10 is retracted into the mounting slot to the maximum extent that the width of the chassis assembly is further reduced.

The base plate assembly 100 of the outdoor unit of the air conditioner provided by the utility model has the characteristics of independent installation, flexible and controllable size and capability of adapting to outdoor units of air conditioners with different widths. In particular, for support stability requirements. The chassis 20 includes at least 3 feet 10. And at least 3 feet 10 are arranged at intervals. In the base plate assembly 100 of the outdoor unit of the air conditioner according to the present invention, a separate mounting groove is formed on the base plate 20 for each of the feet 10. With this arrangement, each of the feet 10 is individually installed, and there is no fixing section between the feet 10, i.e., there is no limitation in the width dimension thereof. The separately installed bottom foot 10 of the present invention solves the problem that the chassis assembly 100 of the outdoor unit of the air conditioner in the prior art cannot be adapted to outdoor units of air conditioners with different widths.

However, since the fixing section for connecting the two feet 10 and fixing the two feet to the bottom surface of the base plate 20 is eliminated, the supporting strength of the separately provided feet 10 is reduced. The foot 10 was subjected to simulation analysis and had a maximum stress of about 2.7346e8Pa for a conventional foot 10 inclined at 45 degrees. Whereas for the proposed separately provided foot 10 of the present invention the maximum stress is increased to 4.196e8 Pa. Thus, in an alternative embodiment, the foot 10, and in particular the support portion 11, is specially designed to increase its structural strength and thus its support capacity.

Referring to fig. 3, in an alternative embodiment, the height of the supporting portion 11 is greater than the height of the fixing portion 12. Specifically, the supporting portion 11 is used for supporting the chassis 20, and performing a load-bearing, fixing and supporting function on a workpiece mounted on the chassis 20. The fixing hole 121 is provided in the fixing portion 12 for mounting the foot 10 to the mounting surface. The mounting surface may be the chassis 20 when the cabinet is installed or other suitable mounting surface. The prior art foot 10, with its mounting holes completely exposed at the edge of the base plate 20, provides a somewhat increased width of the base plate assembly. And further, the width of the packaging structure of the air conditioner outdoor unit is increased, and the cabinet loading rate is reduced. In the bottom foot 10 of the present invention, since the bottom plate 20 is provided with the mounting groove recessed inwards from the side wall, the bottom foot 10 partially extends into the mounting groove. This reduces the width of the chassis assembly. Further, there is a height difference between the supporting portion 11 and the fixing portion 12. That is, the fixing portion 12 may partially extend into the mounting groove, and a gap may exist between the fixing portion 12 extending into the mounting groove and the bottom surface of the chassis 20. In this way, a certain installation space is left for the fixing hole 121 and the fixing member extending into the fixing hole 121. The fixing hole 121 may only partially protrude from the recess of the side wall of the chassis 20, as long as the fixing member can be inserted and installed.

In order to further increase the support strength of the support portion 11, the support portion 11 is specially designed and contributes to further miniaturization of the foot 10. Through experimental analysis, the foot 10 proposed by the present invention saves 30% of material compared to the conventional foot 10. Hereinafter, referring to fig. 4, there are 3 possible embodiments of the foot 10 after its structural design, and in an alternative embodiment, the top surface of the supporting portion 11 is formed with a reinforcing protrusion 113 protruding upward. On the basis of the above embodiment, the reinforcing boss 113 is formed in the middle of the top surface of the support portion 11. And the reinforcing bosses 113 may be disposed in a trapezoidal table shape.

Referring to fig. 5, in an alternative embodiment, the top surface of the supporting portion 11 is recessed downward to form a reinforcing groove 114. Alternatively, the reinforcing groove 114 may be a square groove or a circular groove. On the basis of the above alternative embodiment, the reinforcing groove 114 is a circular groove, and the reinforcing groove 114 is opened in the middle of the top surface of the supporting portion 11.

Referring to fig. 6, in an alternative embodiment, the supporting portion 11 includes a first supporting section 111 and a second supporting section 112, the second supporting section 112 is disposed between the first supporting section 111 and the fixing portion 12, and a height of the first supporting section 111 is smaller than a height of the second supporting section 112. On the basis of the above embodiment, a smooth transition section 115 is further disposed between the first transition section and the second transition section.

In an alternative embodiment, the support portion 11 is embedded in the inner wall of the mounting groove. Specifically, the top surface of the support portion 11 is provided with additional reinforcing structures, such as reinforcing grooves 114 and reinforcing bosses 113, for increasing the structural strength thereof. The bottom surface of the chassis 20 corresponding to the mounting groove is provided with a corresponding bulge or groove. So that the bottom foot 10 is more firmly installed in the installation groove.

By performing a stress analysis simulation on the embodiments, under the same parameter conditions as those of the previous tests, the maximum stress is about 9.223e7Pa, and the maximum stress is remarkably reduced by 4.196e8Pa compared with the foot 10 which is not structurally designed and is separately arranged. Compared with the traditional foot 10 with a fixed section, the maximum stress of the foot is reduced from 2.7346e8Pa to 9.223e7Pa, and the structural strength and the supporting capacity are also obviously improved. In summary, the footing 10 provided by the present invention is independently arranged, and the structural strength and the supporting capability are enhanced through a special structural design.

Referring to fig. 3, in an alternative embodiment, a smooth transition section 115 is disposed at a connection position of the supporting portion 11 and the fixing portion 12. In another embodiment, a smooth transition section 115 is also provided at the junction of the first support section 111 and the second support section 112. The rounded transition section 115 provides a more aesthetic appearance to the foot 10. In addition, the rounded transition section 115 gradually decreases in height from the supporting portion 11 to the fixing portion 12. The rounded transition 115 has the effect of distributing stress. The smooth transition section 115 improves the structural strength of the joint between the support part 11 and the fixing part 12. The effect of increasing the structural strength is also similar to the effect of providing a smooth transition section 115 between the first support section 111 and the second support section 112. In an alternative embodiment, the smooth transition section 115 gradually transitions from top to bottom, and reinforcing ribs are further disposed on two sides of the smooth transition section 115 to further increase the structural strength of the foot 10.

Referring to fig. 3, in an alternative embodiment, the supporting portion 11 is disposed in a trapezoidal shape. In another alternative embodiment, the supporting portion 11 may be in the shape of other regular or irregular cube. The trapezoidal shape is a relatively common structure of the support portion 11. The trapezoidal support portion 11 has a strong supporting ability with the same supporting strength as compared with the support portion 11 having other shapes. Meanwhile, the trapezoidal supporting part 11 also has the characteristics of easy processing and material saving. Which contributes to cost control and miniaturization of the foot 10.

Referring to fig. 3 to 6, in an alternative embodiment, a flange 116 is disposed on the outer periphery of the bottom foot 10. Specifically, the bottom foot 10 is in a trapezoidal shape. The flange 116 is formed by extending outwards from the periphery of the bottom of the foot 10. The provision of the flange 116 increases the stability of the foot 10, so that a larger contact area exists between the foot 10 and the mounting plane of the foot 10. On the basis of the last alternative embodiment, the flange 116 is parallel to the mounting plane of the foot 10. Furthermore, the length of the flange 116 extending from the outer periphery of the foot 10 depends on the size of the foot 10 itself.

Referring to fig. 1 and fig. 2, in an alternative embodiment, the chassis assembly includes 4 bottom feet 10, 4 mounting slots are correspondingly disposed on the chassis 20, the chassis 20 has two opposite side walls, and each side wall is provided with 2 mounting slots disposed at intervals. The manufacturing cost and the stability of the support are comprehensively considered. The number of the feet 10 is controlled between 3 and 8. The air conditioner outdoor unit and the packaging structure of the air conditioner outdoor unit are usually arranged in a cube shape. For ease of binning, the base pan 20 is also often rectangular in shape. Optionally, the bottom plate assembly includes 4 feet 10 symmetrically arranged two by two. The chassis 20 is provided with two opposite side walls, each side wall is recessed inwards to form 2 mounting grooves arranged at intervals, and 4 bottom feet 10 are correspondingly mounted in the mounting grooves. In another alternative embodiment, the bottom plate 20 may also be configured in a special shape, and the feet 10 are disposed at intervals on the bottom surface of the bottom plate 20. The opening position of the mounting groove can be determined according to the shape of the chassis 20, so that a chassis assembly with better supporting strength, supporting stability and stronger impact resistance can be obtained.
