Description

Technical Field

[0001] This invention relates to a device and structure, and more particularly to an antenna device and a waterproof structure. Background Technology

[0002] Most existing waterproof structures for antennas consist of a closed-loop soft rubber (e.g., a circular rubber ring) fitted between the upper and lower brackets to achieve waterproofing. However, during the hot-pressing process, the shrinkage rate of this closed-loop soft rubber is often difficult to control accurately, affecting the waterproofing effect (especially for large-sized products). Furthermore, the dimensions of the molded closed-loop soft rubber are difficult to measure precisely, making it impossible to estimate the amount of stretching and deformation when installed on the upper and lower brackets, which also leads to poor reliability of the waterproofing.

[0003] Therefore, the inventor believed that the above-mentioned defects could be improved, and thus devoted himself to research and applied scientific principles, and finally proposed an invention that is reasonably designed and effectively improves the above-mentioned defects. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an antenna device and a waterproof structure that address the shortcomings of the prior art.

[0005] This invention discloses an antenna device, comprising: an antenna; and a waterproof structure for housing the antenna. The waterproof structure includes: a first housing having a plurality of elongated slots arranged in a geometric shape and interconnected, one of the elongated slots having: two connecting segments and two fixed segments, one end of each of the two connecting segments being connected to an adjacent elongated slot, one end of each of the two fixed segments being connected to the other end of the respective two connecting segments, each of the two fixed segments having an interior angle, and the interior angles of the two fixed segments pointing toward each other; and a plurality of protrusions formed on opposite inner surfaces of each of the fixed segments; a waterproof member disposed on the plurality of elongated slots, the waterproof member having two opposite free ends, the two free ends being abutted by the plurality of protrusions located within the two fixed segments; and a second housing mounted on the first housing, the second housing abutting against the waterproof member, and together with the first housing forming a waterproof space for housing the antenna.

[0006] This invention also discloses a waterproof structure for housing an antenna. The waterproof structure includes: a first housing having a plurality of elongated slots arranged in a geometric shape and interconnected, one of the elongated slots having: two connecting sections and two fixing sections, one end of each of the two connecting sections being connected to an adjacent elongated slot, one end of each of the two fixing sections being connected to the other end of the respective two connecting sections, each of the two fixing sections having an interior angle, and the interior angles of the two fixing sections pointing toward each other; and a plurality of protrusions formed on opposite inner surfaces of each of the fixing sections; a waterproof member disposed on the plurality of elongated slots, the waterproof member having two opposite free ends, the two free ends being abutted by the plurality of protrusions located in the two fixing sections respectively; and a second housing mounted on the first housing, the second housing abutting against the waterproof member, and together with the first housing forming a waterproof space for housing the antenna.

[0007] In summary, the antenna device and waterproof structure disclosed in the embodiments of the present invention can be designed to be strip-shaped and non-enclosed by the design of "the inner angles of the two fixed segments facing each other and the plurality of protrusions forming on the opposite inner surfaces of each fixed segment" and "the two free ends of the waterproof component being abutted by the plurality of protrusions located in the two fixed segments respectively".

[0036] The following specific embodiments illustrate the implementation of the "dual-polarized antenna structure" disclosed in this invention. Those skilled in the art can understand the advantages and effects of this invention from the content disclosed in this specification. This invention can be implemented or applied through other different specific embodiments, and various details in this specification can also be modified and changed based on different viewpoints and applications without departing from the concept of this invention. Furthermore, the accompanying drawings of this invention are for simple illustrative purposes only and are not depictions of actual dimensions; this is stated beforehand. The following embodiments will further describe the relevant technical content of this invention in detail, but the disclosed content is not intended to limit the scope of protection of this invention.

[0037] It should be understood that while terms such as "first," "second," and "third" may be used in this document to describe various components or signals, these components or signals should not be limited by these terms. These terms are primarily used to distinguish one component from another, or one signal from another. Furthermore, the term "or" as used herein should, as appropriate, include any combination of one or more of the related listed items.

[0038] See Figures 1 to 10 As shown, this embodiment provides an antenna device 100. Figure 1 and Figure 2 As shown, the antenna device 100 includes an antenna 1 and a waterproof structure 2 for housing the antenna 1. It should be noted that although the antenna 1 and the waterproof structure 2 are collectively defined as the antenna device 100 in this embodiment, the present invention is not limited thereto. For example, the waterproof structure 2 can be used alone (e.g., implemented, manufactured, sold, etc.) or in conjunction with other components. The structure of each component of the antenna device 100 will be described below, and the connection relationships between the components of the antenna device 100 will be explained as appropriate.

[0039] like Figure 2 and Figure 3 As shown, the waterproof structure 2 in this embodiment is a cuboid structure, but the present invention is not limited thereto. The waterproof structure 2 includes a first housing 21, a waterproof component 22 disposed on the first housing 21, and a second housing 23 disposed on the first housing 21 and covering the waterproof component 22.

[0040] like Figures 3 to 5 As shown, the first housing 21 has a plurality of straight elongated slots 211. These slots 211 are arranged along the four sides of the first housing 21 and are interconnected, forming a rectangular geometry. Notably, one of the elongated slots 211 is different from the others and can be used to fix the two free ends 221 of the waterproof component 22.

[0041] Specifically, one of the elongated slots 211 has two connecting segments 2111, two fixed segments 2112, and a plurality of protrusions 2113. One end of each of the two connecting segments 2111 is connected to an adjacent elongated slot 211, and one end of each of the two fixed segments 2112 is connected to the other end of the respective two connecting segments 2111. Each of the two fixed segments 2112 has an interior angle θ, and the interior angles θ of the two fixed segments 2112 point towards each other. Alternatively, it can be understood that each of the two fixed segments 2112 is roughly in the shape of a reclining V, and the openings of the two fixed segments 2112 face towards each other.

[0042] Preferably, the angles of each of the interior angles are between 80 degrees and 140 degrees. Accordingly, the waterproof element 22 located within the two fixed sections 2112 can more effectively achieve the purpose of waterproofing.

[0043] It is worth noting that, in one embodiment, the other end of the two fixed segments 2112 may be a connection between the two connecting segments 2111. For example... Figure 9 As shown, in another application example, the other end of the two fixed segments 2112 may not be connected to the two connecting segments 2111.

[0044] Cooperate Figure 5 As shown, a plurality of protrusions 2113 are formed on opposite inner surfaces of each of the fixing segments 2112. That is, in each fixing segment 2112, the plurality of protrusions 2113 may be staggered on the two inner surfaces. Accordingly, the plurality of protrusions 2113 located in each fixing segment 2112 can be used to abut against the free end 221 of the waterproof component 22. Preferably, the thickness of each protrusion 2113 is between 10% and 75% of the diameter of the waterproof component 22. This allows the plurality of protrusions 2113 located in the two fixing segments 2112 to securely limit the two free ends 221 and prevent water vapor from seeping in, but does not affect the smoothness of assembly of the waterproof component 22 (e.g., when the thickness of each protrusion 2113 is too thick, the waterproof component 22 is blocked by the plurality of protrusions 2113 and is not easy to insert into the elongated groove).

[0045] like Figure 3 and Figure 5As shown, the waterproof component 22 in this embodiment is a strip-shaped soft rubber with two opposite free ends 221, but the invention is not limited to this material. The waterproof component 22 is disposed on a plurality of elongated grooves 211, and the two free ends 221 are respectively abutted by a plurality of protrusions 2113 located in two fixed sections 2112, thereby restricting movement. In this embodiment, when the waterproof component 22 is disposed in the plurality of elongated grooves 211, a portion of the waterproof component 22 will protrude from the side of the first housing 21 facing the second housing 23 (e.g., Figure 8 (As shown).

[0046] Preferably, the diameter of the waterproof element 22 can be smaller than the width of each of the elongated grooves 211 and larger than the depth of the elongated grooves 211. Accordingly, the waterproof element 22 can be more easily disposed within the plurality of elongated grooves 211, and its parts can protrude outside the plurality of elongated grooves 211.

[0047] like Figure 2 and Figure 6 As shown, the second housing 23 is mounted on the first housing 21, and the second housing 23 abuts against the waterproof component 22, and together with the first housing 21, forms a waterproof space S for accommodating the antenna 1.

[0048] In one embodiment, the side 231 of the second housing 23 facing the first housing 21 is flat, and when the second housing 23 is disposed on the first housing 21, the side 231 can abut (or squeeze) the waterproof component 22 and deform, so that the waterproof component 22 seals the gap between the second housing 23 and the first housing 21.

[0049] In another practical application, such as Figure 10 As shown, the second housing 23' may also have a mating groove 232, the geometry of which corresponds to the plurality of elongated grooves 211, and the portion of the waterproof component 22 is located within the mating groove 232, deforming against the inner side of the mating groove 232. Accordingly, the waterproof component 22 fills the (partial) space within the plurality of elongated grooves 211 and the mating groove 232 to achieve a waterproof effect.
