Description

Technical Field

[0001] This disclosure relates to the field of antenna technology, and in particular to a housing structure and antenna module for antenna packaging. Background Technology

[0002] Antennas are an indispensable component of wireless communication systems. They are responsible for converting the high-frequency electrical energy generated by the transmitter into electromagnetic waves that are radiated into space, or for converting the received electromagnetic waves into high-frequency electrical energy for the receiver to process.

[0003] Antennas typically consist of a circuit board and a radiating component for transmitting and receiving signals. For antennas used outdoors, the circuit board and radiating component are usually installed inside the housing for protection and ease of assembly. In existing technologies, considering that metal housings can generate electromagnetic interference, antenna shells are often injection molded. To ensure the housing also has heat dissipation capabilities, a grid heat dissipation structure is often installed around the perimeter or top of the housing. This structure includes multiple grid strips, and for better heat dissipation and a more aesthetically pleasing appearance, these grid strips are often angled towards the housing. This results in difficulties in demolding the integrally molded grid strips during injection molding, and may even lead to cracking of the grid heat dissipation structure during demolding, resulting in a decrease in product yield.

[0004] Therefore, there is an urgent need for an antenna structure that is easy to demold and has good heat dissipation. Utility Model Content

[0005] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a housing structure and antenna module for antenna packaging that is easy to demold and has better waterproof performance.

[0006] The purpose of this disclosure is achieved through the following technical solution:

[0007] A housing structure for antenna packaging, comprising:

[0008] The housing and the grille assembly are provided. The housing has a clearance groove on its periphery. The grille assembly includes multiple grille members, all of which are located in the clearance groove. The multiple grille members and the housing together form a receiving cavity that communicates with the clearance groove. The receiving cavity is used to receive the antenna.

[0009] Multiple grille members are stacked and arranged, and each grille member is detachably connected to the housing. Each grille member has a bent shielding part formed on the side away from the relief groove. Each bent shielding part has a preset angle with the corresponding grille member so that a heat dissipation channel communicating with the accommodating cavity is formed between two adjacent grille members. The heat dissipation channel is used for ventilation and heat dissipation.

[0010] In one embodiment, each of the grille members includes a connecting post and an annular bar, the connecting post being connected to the annular bar, the bent shielding portion being formed on the side of the annular bar away from the connecting post, and the connecting posts of two adjacent grille members abutting each other so that the two adjacent grille members form the heat dissipation channel.

[0011] The connecting post has a first screw hole, and the first screw holes of two adjacent connecting posts are arranged opposite each other. The housing has a second screw hole corresponding to the first screw hole. The first screw hole and the second screw hole are used for screws to pass through so that the grid strip is screwed to the housing.

[0012] In one embodiment, the annular strip is inclinedly disposed on the connecting post so that the cross-section between the annular strip and the bent blocking portion is "V" shaped.

[0013] In one embodiment, one end of the connecting post is provided with a guide portion, and the guide portion and the connecting post together form an embedding groove. When two adjacent connecting posts abut each other, one end of one of the connecting posts is embedded in the embedding groove.

[0014] In one embodiment, the connecting column and the annular strip are integrally injection molded structures.

[0015] In one embodiment, there are multiple connecting posts, which are spaced apart on the inner side of the annular strip.

[0016] In one embodiment, the housing includes a bottom cover and an upper cover, the bottom cover and the upper cover being detachably connected, the clearance groove being formed at the periphery of the upper cover, and the grille assembly being located between the bottom cover and the upper cover.

[0017] In one embodiment, the housing structure for antenna packaging further includes a decorative shell, the top of which has an accommodating groove, and a portion of the decorative shell is located within the accommodating groove and connected to the upper shell.

[0018] In one embodiment, a portion of the bottom cover is recessed inward to form a groove, and the bottom wall of the groove has a connecting hole for a screw to pass through so that the end of the screw is located within the groove.

[0019] An antenna module includes a signal antenna and a housing structure for antenna encapsulation as described in any of the above embodiments, wherein the signal antenna is installed inside the housing.

[0020] Compared with the prior art, this disclosure has at least the following advantages:

[0021] 1. The aforementioned housing structure for antenna packaging has a recessed groove in the housing. The grille assembly includes multiple grille pieces, all of which are located within the recessed groove. The multiple grille pieces and the housing together form an accommodating cavity to accommodate the antenna within the accommodating cavity. The multiple grille pieces are stacked, and each grille piece is detachably connected to the housing. That is, the grille assembly is not integrally formed, but rather multiple grille pieces are formed and then assembled onto the housing. Compared to the integrally formed grille assembly in traditional technology, the grille assembly of this application is easier to demold, thereby ensuring product yield.

[0022] 2. In the aforementioned housing structure for antenna packaging, each grille has a bent shielding part formed on the side away from the clearance groove, and each bent shielding part has a preset angle with the corresponding grille, so that a heat dissipation channel is formed between two adjacent grilles, allowing the heat generated inside the housing to be discharged through the heat dissipation channel, thereby improving the heat dissipation effect of the housing structure, and also achieving the effect of waterproofing and dustproofing.

[0028] To facilitate understanding of this disclosure, a more complete description will be given below with reference to the accompanying drawings, which illustrate preferred embodiments of the present disclosure. However, this disclosure can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure.

[0029] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] This disclosure provides a housing structure for antenna packaging, including a housing and a grille assembly. The housing has a recessed groove around its periphery. The grille assembly includes multiple grille members, all located within the recessed groove. The multiple grille members and the housing together form a receiving cavity communicating with the recessed groove. The receiving cavity is used to house the antenna. The multiple grille members are stacked, and each grille member is detachably connected to the housing. Each grille member has a bent shielding portion on its side away from the recessed groove. Each bent shielding portion has a preset angle with its corresponding grille member, so that a heat dissipation channel communicating with the receiving cavity is formed between two adjacent grille members. The heat dissipation channel is used for ventilation and heat dissipation.

[0032] The aforementioned housing structure for antenna encapsulation includes a recessed groove in the housing. The grille assembly comprises multiple grille elements, all located within the recessed groove. These grille elements, together with the housing, form a receiving cavity to house the antenna. The multiple grille elements are stacked, and each grille element is detachably connected to the housing. This means the grille assembly is not integrally formed, but rather multiple grille elements are formed and then assembled onto the housing. Compared to the integrally formed grille assemblies of traditional technologies, the grille assembly of this application is easier to demold, thus ensuring product yield. Because each grille element has a bent shielding portion formed on the side away from the recessed groove, and each bent shielding portion has a preset angle with the corresponding grille element, a heat dissipation channel is formed between adjacent grille elements. This allows heat generated inside the housing to dissipate through the heat dissipation channel, resulting in better heat dissipation of the housing structure and also providing waterproofing and dustproofing.

[0033] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0034] like Figures 1 to 4 As shown, an embodiment of the housing structure for antenna packaging includes a housing 100 and a grid assembly 200. The housing 100 has a clearance groove 110 on its periphery. The grid assembly 200 includes a plurality of grid members 210, all of which are located within the clearance groove 110. The plurality of grid members 210 and the housing 100 together form a receiving cavity that communicates with the clearance groove 110. The receiving cavity is used to receive the antenna so as to cover the antenna within the housing 100 and the grid assembly 200.

[0035] Furthermore, multiple grille members 210 are stacked, and each grille member 210 is detachably connected to the housing 100. Each grille member 210 has a bent shielding part 220 formed on the side away from the relief groove 110. Each bent shielding part 220 has a preset angle with the corresponding grille member 210, so that a heat dissipation channel 230 communicating with the accommodating cavity is formed between two adjacent grille members 210. The heat dissipation channel 230 is used for ventilation and heat dissipation.

[0036] In this embodiment, a clearance groove 110 is provided on the periphery of the housing 100. The grille assembly 200 includes multiple grille pieces 210, all of which are located within the clearance groove 110. This allows the multiple grille pieces 210 and the housing 100 to form an accommodating cavity, so that the antenna is enclosed within the housing 100 and the multiple grille strips. The multiple grille pieces 210 are stacked, and each grille piece 210 is detachably connected to the housing 100. That is, the multiple grille pieces 210 are not integrally formed, but are assembled separately on the housing 100. Compared with the integral grille assembly 200 in the conventional technology, this application sets the grille assembly 200 as a separate unit, that is, by injection molding multiple grille pieces 210 separately and then assembling them on the housing 100, the demolding of the grille pieces 210 is simpler, avoiding the cracking problem that occurs when the product is demolded. Furthermore, on the side of the grille 210 away from the recess 110, that is, the outer side of the grille 210 after bending, a bent shielding part 220 is formed. The bent shielding part 220 and the corresponding grille 210 have a preset angle, so that a heat dissipation channel 230 is formed between two adjacent grille parts 210. The heat dissipation channel 230 is used for ventilation and heat dissipation, which improves the heat dissipation function of the housing 100 structure. Due to the shielding of the bent shielding part 220, a certain dustproof and waterproof effect is achieved, and the antenna inside the housing 100 is difficult to see with the naked eye through the shielding part, making the product more aesthetically pleasing.

[0037] The aforementioned housing structure for antenna encapsulation includes a housing 100 with a recessed groove 110. The grille assembly 200 comprises multiple grille elements 210, all located within the recessed groove 110. The multiple grille elements 210 and the housing 100 together form a receiving cavity to house the antenna. The multiple grille elements 210 are stacked, and each grille element 210 is detachably connected to the housing 100. That is, the grille assembly 200 is not integrally formed, but rather multiple grille elements 210 are formed and then assembled onto the housing 100. This differs from the integrally formed design in traditional technologies. The grid assembly 200 of this application is easier to demold, thereby ensuring product yield. Since each grid piece 210 has a bent blocking part 220 formed on the side away from the relief groove 110, and each bent blocking part 220 has a preset angle with the corresponding grid piece 210, a heat dissipation channel 230 is formed between two adjacent grid pieces 210, so that the heat generated inside the housing 100 can be discharged through the heat dissipation channel 230, thereby making the heat dissipation effect of the housing 100 structure better, and also playing a role in waterproofing and dustproofing.

[0038] like Figure 4 As shown, in one embodiment, each of the grille members 210 includes a connecting post 211 and an annular strip 212. The connecting post 211 is connected to the annular strip 212. The bent shielding portion 220 is formed on the side of the annular strip 212 away from the connecting post 211. The connecting posts 211 of two adjacent grille members 210 abut against each other so that the two adjacent grille members 210 form the heat dissipation channel 230.

[0039] The connecting post 211 has a first screw hole 211a. The first screw holes 211a of two adjacent connecting posts 211 are arranged opposite to each other. The housing 100 has a second screw hole corresponding to the first screw hole 211a. The first screw hole 211a and the second screw hole are used for screws to pass through so that the grid strip is screwed to the housing 100.

[0040] In this embodiment, the connecting posts 211 of two adjacent grid members 210 abut against each other, and there is a certain gap between two adjacent annular bars 212. The bent shielding part 220 is formed on the outside of the annular bar 212, so that the two adjacent grid members 210 form a heat dissipation channel 230 for ventilation and heat dissipation. The connecting post 211 is provided with a first screw hole 211a, and the first screw holes 211a of two adjacent connecting posts 211 are correspondingly provided. The housing 100 is provided with a second screw hole corresponding to the first screw hole 211a. During assembly, multiple grid members 210 are stacked and then the multiple grid members 210 and the housing 100 are fixed by screws. By setting the grid assembly 200 as a split structure, it is easier to demold the grid assembly 200 during injection molding.

[0041] Furthermore, in other embodiments, the grille can also be fixed to the housing by snap-fit.

[0042] like Figure 4 As shown, in one embodiment, the annular strip 212 is inclinedly disposed on the connecting post 211, so that the cross-section between the annular strip 212 and the bent shielding part 220 is V-shaped. It can be understood that the annular strip 212 is inclinedly disposed on the connecting post 211, and the outer side of the annular strip 212 is bent to form the bent shielding part 220. This makes the cross-section between the annular strip 212 and the bent shielding part 220 V-shaped, meaning the heat dissipation channel 230 is also V-shaped, increasing the area of ​​the heat dissipation channel 230 and resulting in better heat dissipation.

[0043] like Figure 4 As shown, in one embodiment, one end of the connecting post 211 is provided with a guide portion 211b. The guide portion 211b and the connecting post 211 together form an embedding groove. The embedding groove is used so that when two adjacent connecting posts 211 abut, one end of one of the connecting posts 211 is embedded in the embedding groove. In this embodiment, the guide portion 211b and the connecting post 211 together form an embedding groove, and two adjacent connecting posts 211 are stacked, that is, one end of one connecting post 211 is embedded in the embedding groove, which makes the fixing effect between two adjacent grid members 210 better.

[0044] In one embodiment, the connecting post 211 and the annular strip 212 are integrally injection molded structures, so that the connecting post 211 and the annular strip 212 have higher structural strength and a more compact structure.

[0045] like Figure 3 and Figure 4 As shown, in one embodiment, there are multiple connecting posts 211, which are spaced apart and arranged inside the annular strip 212. It can be understood that each grid member 210 includes an annular strip 212 and multiple connecting posts 211, with the multiple connecting posts 211 spaced apart inside the annular strip 212. The connecting posts 211 between adjacent grid members 210 are correspondingly arranged, resulting in better fixing effect between adjacent grid members 210.

[0046] like Figure 2As shown, in one embodiment, the housing 100 includes a bottom cover 120 and an upper cover 130, the bottom cover 120 and the upper cover 130 being detachably connected, the recessed groove 110 being formed at the periphery of the upper cover 130, and the grille assembly 200 being located between the bottom cover 120 and the upper cover 130. In this embodiment, the bottom cover 120 and the upper cover 130 are screwed together for easy assembly and disassembly, and the grille assembly 200 is located between the bottom cover 120 and the upper cover 130 so that the antenna is covered by the bottom cover 120, the upper cover 130 and the grille assembly 200.

[0047] like Figure 1 and Figure 2 As shown, in one embodiment, the housing structure for antenna encapsulation further includes a decorative shell 300. A receiving groove 131 is formed on the top of the upper shell 130, and a portion of the decorative shell 300 is located within the receiving groove 131 and connected to the upper shell 130. In this embodiment, the decorative shell 300 is located within the receiving groove 131 and connected to the upper shell 130, serving a decorative function to make the housing 100 structure more aesthetically pleasing.

[0048] like Figure 1 As shown, in one embodiment, a portion of the bottom cover 120 is recessed inward to form a groove 121. A connecting hole is provided on the bottom wall of the groove 121 for a screw to pass through, so that the end of the screw is located within the groove 121. In this embodiment, the middle portion of the bottom cover 120 is recessed inward to form the groove 121. A connecting hole is provided at the bottom of the groove 121. After the screw passes through the connecting hole, the antenna is fixed to the bottom cover 120, and the end of the screw is hidden within the groove 121, further enhancing the aesthetics of the housing 100 structure.

[0049] This application also provides an antenna module, including a signal antenna and a housing structure for antenna encapsulation as described in any of the above embodiments, wherein the signal antenna is installed inside the housing 100.

[0050] Compared with the prior art, this disclosure has at least the following advantages:

[0051] 1. In the aforementioned housing structure for antenna packaging, the housing 100 has a recessed groove 110, and the grille assembly 200 includes multiple grille pieces 210, all of which are located within the recessed groove 110. The multiple grille pieces 210 and the housing 100 together form an accommodating cavity to accommodate the antenna within the accommodating cavity. The multiple grille pieces 210 are stacked, and each grille piece 210 is detachably connected to the housing 100. That is, the grille assembly 200 is not integrally formed, but rather multiple grille pieces 210 are formed and then assembled onto the housing 100. Compared to the integrally formed grille assembly 200 in the conventional technology, the grille assembly 200 of this application is easier to demold, thereby ensuring product yield.

[0052] 2. In the above-mentioned housing structure for antenna packaging, each grille 210 has a bent shielding part 220 formed on the side away from the relief groove 110, and each bent shielding part 220 has a preset angle with the corresponding grille 210, so that a heat dissipation channel 230 is formed between two adjacent grilles 210, so that the heat generated inside the housing 100 can be discharged through the heat dissipation channel 230, thereby making the heat dissipation effect of the housing 100 structure better, and also playing a role in waterproofing and dustproofing.

[0053] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this patent disclosure. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure.
