[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0033] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.
[0034] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
[0035] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.
[0036] See also Figure 1 As shown, according to an embodiment of the utility model, a top cover 100 of an air conditioner outdoor unit is provided, and a first main pressure rib 1 and a second main pressure rib 2 are provided on the top cover 100 of the air conditioner outdoor unit. The first main pressure rib 1 and the second main pressure rib 2 both extend along the length direction of the top cover 100 of the air conditioner outdoor unit. There are two second main pressure ribs 2, and one second main pressure rib 2, the first main pressure rib 1 and another second main pressure rib 2 are arranged in sequence along the width direction of the top cover 100 of the air conditioner outdoor unit.
[0037] The first main pressure rib 1 has first grooves 12 on both sides along the width direction of the air conditioner outdoor unit top cover 100, and each second main pressure rib 2 extends into the corresponding first groove 12. The first main pressure rib 1 has second grooves 11 on both ends along the length direction of the air conditioner outdoor unit top cover 100, and the air conditioner outdoor unit top cover 100 is provided with first local pressure ribs 3 in each second groove 11.
[0038] In the above example, the first main rib 1 has a second groove 11 at both ends along the length direction of the top cover 100 of the air conditioner outdoor unit. The first main rib 1 forms a double-headed deep fork main rib in the length direction of the top cover 100 of the air conditioner outdoor unit. The first main rib 1 divides the top cover 100 of the air conditioner outdoor unit into four areas, two first groove areas and two second groove areas. The top cover 100 of the air conditioner outdoor unit is provided with a first local rib 3 in each second groove 11, which can play a role in strengthening the strength and improve the strength of the first main rib 1 at the double forks at both ends. The second main ribs 2 on both sides of the first main rib 1 point to the four corners of the top cover 100 of the air conditioner outdoor unit, and each second main rib 2 is substantially the same length as the first main rib 1. Among them, the first main rib 1, the two second main ribs 2 and the two first local ribs 3 cooperate, and the overall ribs of the top cover 100 of the air conditioner outdoor unit of this structure are sharp-edged, not only have good rigidity and strength, but also have very small rebound warping deformation after stamping.
[0039] In some embodiments, Figure 1 As shown, each of the second main pressure ribs 2 has no concave on the side facing away from the first main pressure rib 1, which is suitable for the case where the maximum width of the second main pressure rib 2 is greater than 100 times the material thickness. At this time, although the strength of the second main pressure rib 2 is weak and easy to deform, the overall rigidity of the air conditioner outdoor unit top cover 100 is still good, and the stamping warping is small, which does not affect the use.
[0040] Of course, in other embodiments, such as Figure 2 As shown, each of the second main pressure ribs 2 has a third groove 21 on the side facing away from the first main pressure rib 1. The top cover 100 of the air conditioner outdoor unit is provided with a second local pressure rib 4 in each third groove 21.
[0041] In the above example, by providing the second local rib 4 , the local strength of the air-conditioning outdoor unit top cover 100 at the third groove 21 can be further improved to further reduce the forming warping of the air-conditioning outdoor unit top cover 100 .
[0042] Figure 4 A stress effect diagram of a top cover of an air conditioner outdoor unit in the prior art is disclosed. When the top cover of the air conditioner outdoor unit in the prior art is formed of a material with a yield strength of more than 240 MPa, its distortion is more than 20 mm.
[0043] Figure 5A stress effect diagram of a top cover 100 of an air conditioner outdoor unit of the utility model is disclosed. In the figure, the top cover 100 of the air conditioner outdoor unit of the utility model has a first main pressure rib 1 and two second main pressure ribs 2, both ends of the first main pressure rib 1 have a first groove 12, and each second main pressure rib 2 has a third groove 21 on the side away from the first main pressure rib 1. The top cover 100 of the air conditioner outdoor unit has a first local pressure rib 3 in each first groove 12, and the top cover 100 of the air conditioner outdoor unit has a second local pressure rib 4 in each second groove 11. When the top cover 100 of the air conditioner outdoor unit is formed by a material with a yield strength below 350MPa, its forming distortion is within 4mm, which has obvious advantages.
[0044] In some embodiments, Figure 3 As shown, each of the first partial pressure ribs 3 has a fourth groove 31 on a side away from the first main pressure rib 1. The top cover 100 of the air conditioner outdoor unit is provided with a third partial pressure rib 6 in each fourth groove 31.
[0045] In the above example, by adding the third local rib 6, although the stamping force of the air conditioner outdoor unit top cover 100 is increased, too dense ribs may easily cause excessive thinning of the material, but no cracking occurs during forming, and the stamping warping is small, which does not affect the use.
[0046] It should be noted here that: Figure 3 As shown, the two third local ribs 6 are symmetrically distributed, which is beneficial to balancing the stress on the top cover 100 of the air-conditioning outdoor unit and reducing the forming warping of the top cover 100 of the air-conditioning outdoor unit.
[0047] In some embodiments, Figure 1 As shown, the width of the end of the first main rib 1 is greater than or equal to 2 / 3 of the width of the air conditioner outdoor unit top cover 100. This is conducive to balancing the internal stress in each area divided by the first main rib 1 after stamping, and the rebound warping deformation is small.
[0048] In some embodiments, Figure 1 As shown, the two ends of the air conditioner outdoor unit top cover 100 in the length direction are respectively the first end 101 and the second end 102. The first main pressure rib 1 and the two second main pressure ribs 2 have one end in the length direction at an equal distance from the end surface of the first end 101, that is, the first main pressure rib 1 and the two second main pressure ribs 2 have one end in the length direction flush. The other end of the first main pressure rib 1 and the two second main pressure ribs 2 in the length direction have the same distance from the end surface of the second end 102, that is, the other end of the first main pressure rib 1 and the two second main pressure ribs 2 in the length direction flush.
[0049] In the above example, the lengths of the first main pressure rib 1 and the second main pressure rib 2 are equal, which significantly improves the overall rigidity of the air conditioner outdoor unit top cover 100.
[0050] In some embodiments, Figure 1 As shown, along the length direction of the air conditioner outdoor unit top cover 100 , the aforementioned first main pressure rib 1 is wide at both ends and narrow in the middle, which is conducive to forming the aforementioned first groove 12 on both sides of the first main pressure rib 1 .
[0051] In some embodiments, Figure 1 As shown, the two second main ribs 2 are symmetrically distributed, which is beneficial to balancing the stress on the top cover 100 of the air-conditioning outdoor unit and reducing the forming warping of the top cover 100 of the air-conditioning outdoor unit.
[0052] Similarly, the two aforementioned first local ribs 3 are also symmetrically distributed, which is also beneficial to balancing the stress on the top cover 100 of the air-conditioning outdoor unit and reducing the forming warping of the top cover 100 of the air-conditioning outdoor unit.
[0053] In some embodiments, the aforementioned ribs protrude from the upper end of the air conditioner outdoor unit top cover 100. The height of each rib is 3-8 mm. Preferably, the height of each rib is consistent and is 5.5 mm.
[0054] The draft angles of the aforementioned ribs are all above 20 degrees to facilitate drafting after stamping.
[0055] The edges of the aforementioned ribs have a rounded corner of more than 3 mm to reduce the sharp corners, which is beneficial to reducing the stress concentration phenomenon.
[0056] It should be noted here that the bottom 5 of the aforementioned air-conditioning outdoor unit top cover 100 has a folded edge or a flanged edge structure, which is beneficial for strengthening the side strength of the air-conditioning outdoor unit top cover 100 and plays a supporting role at the same time.
[0057] Among them, the top cover 100 of the air conditioner outdoor unit of the utility model can be processed by using a steel plate material with a yield strength of about 220-380MPa through reasonable design of the ribs, and the forming warping deformation is small, so that the steel plate material with high yield strength can be used to replace the steel plate material with low yield strength to produce the top cover 100 of the air conditioner outdoor unit, so that the strength of the top cover 100 of the air conditioner outdoor unit can be improved. The top cover 100 of the air conditioner outdoor unit with improved strength has obvious improvement in anti-fall and anti-trampling deformation capabilities, and at the same time, the thickness of the material of the top cover 100 of the air conditioner outdoor unit can be appropriately thinned, saving material costs, and having huge economic benefits.
[0058] The utility model also provides an air conditioner outdoor unit, which may include any of the above-mentioned air conditioner outdoor unit top covers 100. Among them, because the air conditioner outdoor unit adopts the above-mentioned air conditioner outdoor unit top cover 100, the air conditioner outdoor unit top cover 100 has clear edges and corners, and not only has good rigidity and strength, but also has very small rebound warping deformation after stamping.
[0059] It is easy for those skilled in the art to understand that, without conflict, the advantageous technical features of the above-mentioned methods can be freely combined and superimposed.
[0060] The above is only a preferred embodiment of the utility model, and is not intended to limit the utility model. Any modifications, equivalent replacements and improvements made within the spirit and principles of the utility model should be included in the protection scope of the utility model. The above is only a preferred implementation of the utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the utility model, and these improvements and variations should also be regarded as the protection scope of the utility model.
