Abstract
Description
Technical Field
[0001] This application relates to the field of antenna technology, and more specifically, to a sealed housing and an antenna device. Background Technology
[0002] External antenna devices are used outdoors and are exposed to severe weather such as rain, requiring strong waterproof capabilities to prevent rainwater from entering and causing damage. Currently, the waterproof rating of internal and external antenna devices in the industry is generally above level 7. The sealing method involves machining a U-shaped groove on the end face of the lower housing, placing the end face of the upper housing inside the U-shaped groove, and then filling the U-shaped groove with glue.
[0003] However, the presence of the U-shaped groove leads to uneven wall thickness in the lower housing, resulting in thickness marks and stress lines at the corresponding areas of the injection-molded lower housing. After the lower and upper housings are assembled, these thickness marks and stress lines are exposed, degrading the user experience. To improve these issues, continuous mold modifications and adjustments to process parameters are necessary, but it is still impossible to completely eliminate thickness marks and stress lines, resulting in significant costs in materials, manpower, and time. Utility Model Content
[0004] The purpose of this application is to address the shortcomings of the prior art by providing a sealed housing and antenna device that can greatly reduce the probability of surface thickness marks and stress marks, thereby reducing processing costs and material costs.
[0005] To achieve the above objectives, the technical solutions adopted in the embodiments of this application are as follows:
[0006] In one aspect of this application, a sealing housing is provided, comprising: a first housing and a second housing mating with the first housing. The first housing includes a first shell plate, a first annular rib disposed on the surface of the first shell plate, and a second annular rib disposed on the end face of the first annular rib facing away from the first shell plate. The second housing includes a second shell plate and a third annular rib and a fourth annular rib disposed on the surface of the second shell plate. The fourth annular rib surrounds the third annular rib. The heights of the third annular rib and the fourth annular rib in the mating direction are both less than 2.5 mm. The second annular rib is disposed between the third annular rib and the fourth annular rib.

[0008] Optionally, the height of the fourth annular girders in the mating direction is greater than the height of the third annular girders in the mating direction.
[0009] Optionally, the gap between the inner wall of the second annular girders and the outer wall of the third annular girders is 0.1 mm to 0.2 mm larger than the gap between the outer wall of the second annular girders and the inner wall of the fourth annular girders.
[0010] Optionally, the gap between the end face of the second annular surrounding bone and the second shell plate is 0.1mm-0.3mm.
[0011] Optionally, the end face of the second annular rib facing away from the first shell plate is inclined from the outer wall of the second annular rib toward the first shell plate. There is no chamfer at the connection between the end face of the second annular rib facing away from the first shell plate and the outer wall of the second annular rib. A chamfer is provided at the connection between the end face of the second annular rib facing away from the first shell plate and the inner wall of the second annular rib.
[0012] Optionally, the maximum distance between the end face of the second annular rib facing away from the first shell plate and the end face of the third annular rib facing away from the second shell plate is greater than 0.3 mm.

[0014] Optionally, the height of the first annular rib in the mating direction is greater than 6 mm.
[0015] In another aspect of the embodiments of this application, an antenna device is provided, including a sealed housing as described in any of the above and an antenna disposed within the sealed housing.
[0016] The beneficial effects of this application include:
[0017] This application provides a sealing housing, comprising: a first housing and a second housing mating with the first housing. The first housing includes a first shell plate, a first annular rib disposed on the surface of the first shell plate, and a second annular rib disposed on the end face of the first annular rib facing away from the first shell plate. The second housing includes a second shell plate and a third and a fourth annular rib disposed on the surface of the second shell plate. The fourth annular rib surrounds the third annular rib. The heights of both the third and fourth annular ribs in the mating direction are less than 2.5 mm. The second annular rib is disposed between the third and fourth annular ribs. After mating, the second annular rib of the sealing housing is concealed between the third and fourth annular ribs. The exposed portion of the first housing does not have a sudden change in wall thickness, thus preventing the exposure of thickness marks and stress marks. The third and fourth annular ribs of the second housing are relatively short, minimizing the appearance of thickness marks and stress marks during injection molding, and requiring less adhesive during sealing. Therefore, the above-mentioned sealing housing can significantly reduce the probability of surface thickness marks and stress marks, thereby reducing processing costs and material costs.

[0031] Regarding one aspect of the embodiments of this application, please refer to Figure 1 A sealed housing 100 is provided, comprising: a first housing 110 and a second housing 120 that engages with the first housing 110, wherein after the first housing 110 and the second housing 120 engage, an accommodating space 130 is formed inside both.
[0032] Please refer to the reference. Figure 2The first shell 110 includes a first shell plate 111, a first annular surrounding bone 112 disposed on the surface of the first shell plate 111, and a second annular surrounding bone 113 disposed on the end face of the first annular surrounding bone 112 opposite to the first shell plate 111. The first shell plate 111 has two opposing surfaces and a side surface connecting the two surfaces. The first annular surrounding bone 112 has an inner wall and an outer wall surrounding the inner wall, and two end faces connecting the inner wall and the outer wall. The second annular surrounding bone 113 also has an inner wall and an outer wall surrounding the inner wall, and two end faces connecting the inner wall and the outer wall. One end face of the first annular surrounding bone 112 is connected to the first shell plate 111, and the opposite end face is connected to the end face of the second annular surrounding bone 113. Optionally, the surface of the first shell plate 111 is an arc surface, and the outer wall of the first annular surrounding bone 112 smoothly transitions to the side surface of the first shell plate 111.
[0033] Please refer to the reference. Figure 3 The second shell 120 includes a second shell plate 121 and a third annular surrounding bone 122 and a fourth annular surrounding bone 123 disposed on the surface of the second shell plate 121, with the fourth annular surrounding bone 123 surrounding the third annular surrounding bone 122. The second shell plate 121 has two opposing surfaces and a side surface connecting the two surfaces. The third annular surrounding bone 122 has an inner wall and an outer wall surrounding the inner wall, and two end faces connecting the inner wall and the outer wall. The fourth annular surrounding bone 123 also has an inner wall and an outer wall surrounding the inner wall, and two end faces connecting the inner wall and the outer wall. The end faces of both the third annular surrounding bone 122 and the fourth annular surrounding bone 123 are connected to the surface of the second shell plate 121. Optionally, the surface of the second shell plate 121 is planar, and the outer wall of the fourth annular surrounding bone 123 smoothly transitions to the side surface of the second shell plate 121.
[0034] Please refer to the reference. Figure 4 The outer wall of the third annular rib 122, the inner wall of the fourth annular rib 123, and the surface of the second shell plate 121 together form a sealing groove 140. The second annular rib 113 is disposed within the sealing groove 140 between the third annular rib 122 and the fourth annular rib 123 to achieve the mating of the first shell 110 and the second shell 120. The gap between the second annular rib 113 and the sealing groove 140 is used to fill with adhesive 200 for sealing and fixing. It is understood that the distance between the outer wall of the third annular rib 122 and the inner wall of the fourth annular rib 123 needs to match the factory's adhesive dispensing process.
[0035] After mating, the second annular rib 113 is concealed between the third annular rib 122 and the fourth annular rib 123. The exposed portion of the first shell 110 does not have a sudden change in wall thickness, thus preventing the exposure of thickness marks and stress lines. The heights H2 of the third annular rib and H3 of the fourth annular rib in the mating direction of the second shell 120 are both less than 2.5 mm, resulting in relatively low heights. This minimizes the likelihood of thickness marks and stress lines during injection molding, and also reduces the amount of adhesive 200 used during sealing. Therefore, the aforementioned sealing shell 100 significantly reduces the probability of surface thickness marks and stress lines, thereby lowering processing costs and material costs.
[0036] It should be noted that the height H2 of the third annular circumference in the mating direction refers to the distance between the two opposite end faces of the third annular circumference 122. Similarly, the height of other annular circumferences in the mating direction also refers to the distance between the two opposite end faces of the annular circumference.
[0037] Alternatively, please refer to Figure 3 and Figure 5 The wall thickness T2 of the third annular rib is greater than half the wall thickness T1 of the second shell plate, and the wall thickness T3 of the fourth annular rib is greater than half the wall thickness T1 of the second shell plate. This further avoids uneven wall thickness of the second shell 120 caused by the formation of the sealing groove 140, which would lead to appearance problems and increased costs.
[0038] It should be noted that the wall thickness T2 of the third annular surrounding bone refers to the vertical distance between the inner and outer walls of the third annular surrounding bone 122. Similarly, the wall thickness of other annular surrounding bones also refers to the vertical distance between the inner and outer walls of the annular surrounding bone.
[0039] Optionally, the height H3 of the fourth annular rib in the mating direction is greater than the height H2 of the third annular rib in the mating direction, thereby preventing glue 200 from overflowing during assembly, affecting the appearance and increasing costs.
[0040] Furthermore, the height H3 of the fourth annular rib in the mating direction is more than 1.2 mm higher than the height H2 of the third annular rib in the mating direction. This further enhances the effect of preventing glue overflow during assembly.
[0041] Alternatively, please refer to Figure 1 and Figure 4 The gap G1 between the inner wall of the second annular rib and the outer wall of the third annular rib is 0.1mm-0.2mm larger than the gap G2 between the outer wall of the second annular rib and the inner wall of the fourth annular rib. This allows the adhesive 200 to flow more easily inward, reducing appearance problems caused by adhesive overflow and thus lowering processing costs.
[0042] Optionally, the gap G3 between the end face of the second annular rib and the second shell plate is 0.1mm-0.3mm, thereby greatly reducing the amount of glue 200 used and reducing material costs while ensuring that glue 200 can play a sealing and fixing role.
[0043] Optionally, the maximum distance between the end face 113a of the second annular rib facing away from the first shell plate and the end face 122a of the third annular rib facing away from the second shell plate is greater than 0.3 mm, so as to ensure that the glue 200 can fill the gap between the second annular rib 113 and the sealing groove 140, and ensure the sealing performance of the sealing shell 100.
[0044] Alternatively, please refer to Figure 4 and Figure 6 The end face 113a of the second annular rib facing away from the first shell plate slopes from the outer wall 113b of the second annular rib towards the first shell plate 111. There is no chamfer at the connection between the end face 113a of the second annular rib facing away from the first shell plate and the outer wall 113b of the second annular rib, but a chamfer is provided at the connection between the end face 113a of the second annular rib facing away from the first shell plate and the inner wall 113c of the second annular rib. This design allows the adhesive 200 to overflow as much as possible inwards, reducing appearance problems caused by adhesive overflow and thus lowering processing costs.
[0045] Alternatively, please refer to Figure 1 The height H1 of the first annular retaining rib in the mating direction is greater than 6 mm. Setting the height H1 of the first annular retaining rib to be larger can increase the accommodating space 130 of the sealing housing 100, thereby accommodating more parts.
[0046] Alternatively, please refer to Figure 2 and Figure 3 The inner wall of the first annular rib 112 and the inner wall of the third annular rib 122 are provided with a male buckle 150 and a female buckle 160 that mates with the male buckle 150. The male buckle 150 and the female buckle 160 are engaged to connect the first housing 110 and the second housing 120 without the need for a separate pressure-holding fixture for fixing with glue 200, thus reducing processing costs.
[0047] Furthermore, there are multiple male buckles 150 and multiple female buckles 160, and their positions correspond one-to-one. The multiple male buckles 150 and multiple female buckles 160 are distributed at intervals along the circumference of the first annular rib 112.
[0048] For example, please refer to Figure 1 , Figure 4 and Figure 5The height H1 of the first annular surrounding bone is 20 mm, the height H2 of the third annular surrounding bone is 1 mm, and the height H3 of the fourth annular surrounding bone is 2.2 mm. The distance between the outer wall of the third annular surrounding bone 122 and the inner wall of the fourth annular surrounding bone 123 is 1.4 mm. The wall thickness T2 of the third annular surrounding bone and the wall thickness T3 of the fourth annular surrounding bone are both 0.6 times the wall thickness T1 of the second shell plate. The angle between the end face 113a of the second annular surrounding bone away from the first shell plate and the horizontal plane is 8°. The gap G1 between the inner wall of the second annular surrounding bone and the outer wall of the third annular surrounding bone is 0.2 mm, the gap G2 between the outer wall of the second annular surrounding bone and the inner wall of the fourth annular surrounding bone is 0.08 mm, and the gap G3 between the end face of the second annular surrounding bone and the second shell plate is 0.25 mm.
[0049] Please refer to Figure 1 This embodiment also provides an antenna device 300, including a sealed housing 100 as described above and an antenna 310 disposed within the sealed housing 100.
[0050] The antenna device 300 includes the same structure and beneficial effects as the sealed housing 100 in the foregoing embodiments. The structure and beneficial effects of the sealed housing 100 have been described in detail in the foregoing embodiments and will not be repeated here.
[0051] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
