Abstract

The invention provides a bottom plate structure, an air conditioning outdoor unit and an air conditioning device. The bottom plate structure comprises a bottom plate body and pump foot bolts, and thebottom plate body is connected with a front panel of the air conditioning outdoor unit through the pump foot bolts. The problems of more shaping processes and low production efficiency between an existing bottom plate structure and the front panel of the air conditioning outdoor unit are solved. The bottom plate structure is simple, the connection between the bottom plate body and the pump foot bolts and the integration of the bottom plate body and the front panel can be completed during the shaping process of the bottom plate body, shaping processes are reduced, the production efficiency is improved, and the stability between the bottom plate body and the overall structure of the front panel is enhanced.

Example Embodiment

[0068] Example 1
[0069] Such as figure 1 As shown, it is a schematic structural diagram of the pump foot bolt 25 of the present invention. Wherein, the pump foot bolt 25 includes a round table 252 and an annular protrusion 253. The annular protrusion 253 is arranged at the lower end of the round table 252. When pressure is applied, the annular protrusion 253 deforms toward the radial direction of the annular protrusion 253. extend.
[0070] In the process of forming the chassis, the annular protrusion 253 is inserted into the hole of the chassis, the upper mold of the chassis presses the circular platform 252 and moves downward, the lower mold resists the annular protrusion 253, and the upper mold moves downward through the circular platform 252 to the annular protrusion 253 is squeezed to deform the annular protrusion 253, and the material around the annular protrusion 253 extends radially toward it. The annular protrusion 253 is squashed to fit the bottom surface of the chassis. After the chassis is formed, the pump foot bolt 25 is also completed. Connect with the chassis.
[0071] In this way, due to the effect of the annular protrusion 253, the pump foot bolt 25 in this embodiment has the function of completing the connection between the pump foot bolt 25 and the chassis during the molding process of the chassis, which reduces the forming process of the chassis and the pump foot bolt 25 and improves Increased production efficiency. During the extrusion process, the pressure will have an impact on the internal stress structure of the annular protrusion 253. Since the annular protrusion 253 is inserted into the chassis hole, the chassis hole will generate a reaction force, which offsets part of the impact of the annular protrusion 253 stress structure and reduces The annular protrusion 253 is at risk of structural fracture during the extrusion process. And the annular protrusion 253 is provided at the lower end of the round table 252. The deformation of the annular protrusion 253 will not affect the main structure of the pump foot bolt 25, and will not affect the connection and fixing function of the pump foot bolt 25 as a fastener. The applicability of the bolt 25 is strong.
[0072] In addition, the annular protrusion 253 has a hollow structure, which can greatly reduce the extrusion force required during the molding process of the chassis, has low requirements on processing equipment, and has high fault tolerance; during the flattening process, the annular protrusion 253 is along the diameter Extending outwards, the stress structure changes little, further reducing the risk of structural fracture.

Example Embodiment

[0073] Example 2
[0074] As the pump foot bolt 25 described above, this embodiment differs from it in that it combines figure 1 As shown, the pump foot bolt 25 in this embodiment includes a bolt body 251, a round table 252 and an annular protrusion 253. The round table 252 is a solid cylinder, the annular protrusion 253 is a hollow ring, and the hollow structure of the annular protrusion 253 makes the annular protrusion 253 more likely to deform when subjected to force. Such as figure 2 As shown, the annular protrusion 253 in this embodiment includes a hollow portion 2531, the hollow portion 2531 is cylindrical, and the material around the annular protrusion 253 is evenly distributed, which facilitates the uniform extension of the material in the radial direction during the extrusion process.
[0075] The upper end of the round table 252 is integrally formed with the lower end of the bolt body 251, and the lower end of the round table 252 is integrally formed with the upper end of the annular protrusion 253, so that the connection between the bolt body 251, the round table 252, and the annular protrusion 253 is relatively stable and the structure is relatively stable. The diameter of the circular table 252 is larger than the annular protrusion 253. In this way, after the circular protrusion 253 is inserted into the hole of the chassis, the circular table 252 can abut against the upper surface of the chassis, thereby positioning the circular protrusion 253; and during the extrusion process, press The position of the annular protrusion 253 can be fixed by holding the circular table 252. The axis of the circular table 252 coincides with the axis of the annular protrusion 253, so that the annular protrusion 253 receives a more uniform force during the extrusion process and can extend more uniformly in the radial direction.
[0076] In this way, the hollow portion 2531 of the annular protrusion 253 in this embodiment is cylindrical, so that the material around the annular protrusion 253 can be uniformly extended in the radial direction during the extrusion process, so that the connection between the pump foot bolt 25 and the chassis is also Relatively strong.

Example Embodiment

[0077] Example 3
[0078] As with the pump foot bolt 25 described above, this embodiment differs from it in that a number of reinforcing ribs are provided inside the annular protrusion 253, and the reinforcing ribs are integrally formed with the inner wall of the hollow portion 2531. During the extrusion process, the reinforcing ribs can prevent the annular protrusion 253 from extending radially inwardly after being compressed. The ribs are evenly distributed inside the annular protrusion 253, parallel to each other in pairs, and the plane of the ribs is perpendicular to the cross section of the annular protrusion 253. This arrangement can ensure the use of a small number of ribs and give full play to the prevention of the ring The protrusion 253 functions to extend radially inwardly after being compressed. In this way, material is saved and the forming effect of the pump foot bolt 25 and the chassis is ensured.
