[0022] To make the objectives, technical solutions, and advantages of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with specific embodiments of the present utility model and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be a direct connection, or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0024] In order to solve the technical problems in the prior art, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments:

[0025] As Figures 1 to 3 shown, an injection molding mechanism with a rib structure according to an embodiment of the present utility model includes a first rib 2 and a second rib 3. The first rib 2 and the second rib 3 are formed on the outer periphery of the water injection port 1. The first rib 2, the second rib 3, and the water injection port 1 form an integrally molded structure. The first rib 2 and the second rib 3 are arranged in a cross pattern, and both the first rib 2 and the second rib 3 are higher than the end face of the water injection port 1.

[0026] By providing the first rib 2 and the second rib 3 on the outer periphery of the water injection port 1 and arranging the first rib 2 and the second rib 3 in a cross pattern, the first rib 2 and the second rib 3 themselves form a part of the housing 7 during injection molding, thereby improving the rigidity and strength around the water injection port 1. The design that both the first rib 2 and the second rib 3 are higher than the end face of the water injection port 1 makes the water injection port 1 sink below the first rib 2 and the second rib 3 during the injection molding process. That is to say, the area around the water injection port 1 left on the audio housing 7 after injection molding will not show a large depression in appearance. Through the structure formed by the first rib 2 and the second rib 3, the appearance of the water injection port 1 of the housing 7 is changed, improving the overall aesthetics.

[0027] The first rib 2, the second rib 3, the water injection port 1, and the housing 7 itself are integrally injection molded. Adopting a rib structure at the outer periphery of the water injection port 1 is different from the original direct connection of the water injection port 1 and the housing 7 in one piece. The first rib 2 and the second rib 3 are added between the water injection port 1 and the housing 7, improving the strength and rigidity of the side of the housing 7 with the water injection port 1 left.

[0028] The end faces of the first rib 2 and the second rib 3 are not higher than the end face of the side of the housing 7 with the water injection port 1 left, that is, the first rib 2, the second rib 3, and the housing 7 visually form a whole, without an overly uneven appearance, ensuring the aesthetics of the housing 7.

[0029] In some embodiments, a side wall rib 4 is further provided. The side wall rib 4 surrounds the periphery formed by the first rib 2 and the second rib 3, and the side wall rib 4 is higher than the end face of the water injection port 1.

[0030] The side wall reinforcing rib 4 is provided on the outer periphery formed by the first reinforcing rib 2 and the second reinforcing rib 3, that is, the first reinforcing rib 2 and the second reinforcing rib 3 extend outward and are connected to the side wall reinforcing rib 4. The reinforcing rib area formed by the side wall reinforcing rib 4, the first reinforcing rib 2, and the second reinforcing rib 3 is formed on the outer periphery of the water injection port 1, and the water injection port 1 sunken inside the housing 7 is beautified by the reinforcing ribs, and at the same time, the rigidity and strength of the water injection port 1 are enhanced.

[0031] The reinforcing rib area can be in the shape of a rectangle, a circle, a rhombus, etc., and its area can be specifically adjusted according to the area of the housing 7 and the size of the water injection port 1.

[0032] In some embodiments, a central reinforcing rib 5 is further provided, and the central reinforcing rib 5 surrounds the outer contour of the water injection port 1. After injection molding, the water injection port 1 is formed with a slightly sunken nest shape. By adding the central reinforcing rib 5 at the outer contour of the water injection port 1, both the strength and rigidity of the sunken part of the water injection port 1 are improved, and the aesthetics of the sunken part of the water injection port 1 is also improved.

[0033] The central reinforcing rib 5 can be circular, rectangular, etc. The first reinforcing rib 2, the second reinforcing rib 3, and the central reinforcing rib 5 are integrally injection molded.

[0034] The central reinforcing rib 5 is formed on the outer contour of the water injection port 1, and the water injection port 1 is decorated by the central reinforcing rib 5. And the outer periphery of the central reinforcing rib 5 is connected to at least one of the first reinforcing rib 2 and the second reinforcing rib 3, and the first reinforcing rib 2 and the second reinforcing rib 3 extend downward and are connected to the outer periphery of the water injection port 1. Also by integral injection molding, the central reinforcing rib 5, the first reinforcing rib 2, the second reinforcing rib 3, and the side wall reinforcing rib 4 form an integrally molded structure, and jointly act to improve the strength and rigidity of the housing 7 at the water injection port 1.

[0035] In some embodiments, the end faces of the first reinforcing rib 2, the second reinforcing rib 3, and the central reinforcing rib 5 are flush. In this regard, the end faces of the first reinforcing rib 2, the second reinforcing rib 3, and the central reinforcing rib 5 together form a flat surface.

[0036] In a specific example, the end face of the side wall reinforcing rib 4 is higher than the end faces of the first reinforcing rib 2, the second reinforcing rib 3, and the central reinforcing rib 5. The end face of the side wall reinforcing rib 4 is flush with the plane of the housing 7. This end face is the face of the first reinforcing rib 2, the second reinforcing rib 3, the central reinforcing rib 5, and the side wall reinforcing rib 4 facing the outside of the housing 7.

[0037] The side wall reinforcing rib 4 is higher than the first reinforcing rib 2, the second reinforcing rib 3 and the central reinforcing rib 5. The side wall reinforcing rib 4 is arranged on the periphery. The side wall reinforcing rib 4 and the first reinforcing rib 2, the second reinforcing rib 3 and the central reinforcing rib 5 form a positioning portion 6. Further, the water injection port 1 sinks below the central reinforcing rib 5, and the first reinforcing rib 2, the second reinforcing rib 3 and the central reinforcing rib 5 jointly sink below the side wall reinforcing rib 4.

[0038] Preferably, a covering member 8 is provided on the positioning portion 6. The thickness of the covering member 8 is the same as the depth of the positioning portion 6. The covering member 8 completely covers the positioning portion 6, covering the reinforcing rib structure composed of the first reinforcing rib 2, the second reinforcing rib 3, the central reinforcing rib 5 and the side wall reinforcing rib 4, making the entire plane of the housing 7 look flat from the outside.

[0039] In practical applications, a label can be pasted in the positioning portion 6. The thickness of the label is the same as the depth of the positioning portion 6. After the label is pasted on the positioning portion 6, the first reinforcing rib 2, the second reinforcing rib 3, the central reinforcing rib 5 and the side wall reinforcing rib 4 are covered by the label, and the plane of the label is flush with the plane of the housing 7, and the overall outer tube of the housing 7 is flat and smooth.

[0040] Preferably, the thickness of the label is 0.10 cm - 0.20 cm and it is made of PET material. That is, the depth of the positioning portion 6 is 0.10 cm - 0.20 cm, and the distance between the end face of the first reinforcing rib 2 and the end face of the side wall reinforcing rib 4 is 0.10 cm - 0.20 cm. Further, the end face of the first reinforcing rib 2 is 0.10 cm - 0.20 cm below the plane of the housing 7. In this way, the reinforcing rib structure composed of the first reinforcing rib 2, the second reinforcing rib 3, the central reinforcing rib 5 and the side wall reinforcing rib 4 is basically flush with the outer surface of the housing 7, and the overall appearance is flat.

[0041] More preferably, the distance between the end face of the first reinforcing rib 2 and the end face of the side wall reinforcing rib 4 / housing 7 is 0.15 cm.

[0042] In some embodiments, the first reinforcing rib 2 and the second reinforcing rib 3 form a grid-like structure. Specifically, the included angle between the first reinforcing rib 2 and the second reinforcing rib 3 is designed to be 90°. The first reinforcing rib 2 is distributed horizontally, and the second reinforcing rib 3 is distributed vertically. The numbers of the first reinforcing rib 2 and the second reinforcing rib 3 are specifically adjusted according to strength and rigidity requirements.

[0043] Generally speaking, the water injection port 1 sinks below the central reinforcing rib 5 and is exposed on the outside of the housing 7. Other places on the inner side of the housing 7 are also provided with structures for enhancing rigidity and strength. The places on the outside of the housing 7 except the water injection port 1 are usually flat and smooth. Using the grid-like reinforcing ribs not only shows a certain degree of aesthetics, avoiding pits at the exposed part of the water injection port 1 of the housing 7 and affecting the overall beauty of the housing 7, but also can overall improve the rigidity and strength at the water injection port 1 of the housing 7.

[0044] In some embodiments, the first reinforcing rib 2, the second reinforcing rib 3, the central reinforcing rib 5, the water injection port 1 and the side wall reinforcing rib 4 are integrally injection-molded.

[0045] It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present invention described here can be implemented in an order other than those illustrated or described here. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device comprising a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0046] In summary, after those of ordinary skill in the art read the documents of the present invention, all other corresponding transformation schemes made without creative mental labor according to the technical solutions and technical concepts of the present invention fall within the scope protected by the present invention.
