Description

Technical Field

[0001] The present disclosure relates to wireless communication devices. Background Art

[0002] The contents described in this section are merely used to provide background information for the present disclosure and do not constitute prior art.

[0003] The wireless communication device is equipped with built-in components and can perform wireless communication functions based on them.

[0004] In order to smoothly send and receive wireless signals, wireless communication devices are often exposed to outdoor environments, such as the top of a building, etc. Therefore, it is very important to protect the internal components of the device from external foreign objects, especially water or moisture.

[0005] In the prior art, the radome and the lower box body are arranged close to each other at the upper part and then connected by bolts.

[0006] Figure 1 This is a front view of a conventional radome connected by bolts. Figure 1 There may be gaps in the screw holes (not shown) formed on the radome 1 of the wireless communication device connected by bolts, so there is a possibility that rainwater or the like may penetrate into the device.

[0007] Furthermore, when the operator performs bolt fastening, there is a possibility that the radome 1 may be deformed due to over-tightening.

[0008] Furthermore, since the operator needs to personally perform bolt connection on the plurality of bolts 2 , the assembly process of the wireless communication device may be very cumbersome.

[0009] In addition, the radome 1 manufactured by bolt connection includes a bolt connection area for bolt connection. As a result, the area occupied by the bolt connection area in the area for arranging the assembled parts inside the radome 1 is reduced. Therefore, the space utilization rate is reduced, resulting in the problem of having to increase the weight of the wireless communication device. Summary of the invention

[0010] 1. Technical issues to be resolved

[0011] Based on this, the main object of the present disclosure is to provide a wireless communication device with a simple manufacturing process.

[0012] Furthermore, a main object of the present disclosure is to provide a wireless communication device having excellent airtightness.

[0013] The technical problems that the present invention is intended to solve are not limited to the technical problems described above, and unmentioned or other technical problems can be clearly understood by a person skilled in the art based on the following description.

[0014] (II) Technical solution

[0015] According to one embodiment of the present disclosure, a wireless communication device is provided, which includes: an antenna cover, which includes a sealing protrusion and a first snap portion formed along at least one side end; a lower box body, which includes a sealing protrusion groove and a second snap portion formed along at least one side end and at least a portion of which can accommodate at least a portion of the sealing protrusion; and a fastener connected to the first snap portion and the second snap portion to fix the lower box body and the antenna cover.

[0024] Hereinafter, some embodiments of the present disclosure are described in detail through exemplary drawings. When assigning reference numerals to the components of each drawing, it should be noted that the same reference numerals are used as much as possible even when the same components are marked in another drawing. Moreover, in the process of describing the present disclosure, if it is considered that the detailed description of the relevant well-known structure or function will confuse the main purpose of the present disclosure, its detailed description will be omitted.

[0025] In the process of describing the components involved in the embodiments of the present disclosure, symbols such as first, second, i), ii), a), b) may be used. The symbols are only used to distinguish the component from other components, and the nature, turn or order of the corresponding components cannot be limited based on the symbols. When the specification records that a part 'includes' or 'has' a component, if there is no clear contrary record, it means that other components are further included rather than excluded.

[0026] In the present disclosure, the 'first direction' refers to the length direction of the radome 110 when the radome 110 is formed roughly in an elongated shape, or the drawing direction of the radome 110 during manufacturing. In addition, the 'bend portion' in the present disclosure refers to a portion where the direction of one surface and another surface adjacent to the one surface changes, and is defined to include all gentle bends or sharp corners. In addition, 'above' and 'below' in the present disclosure refer to the directions in which the height of the lower box body 130 increases and decreases. In addition, 'side' refers to the area between the top and the bottom. However, the definitions of these terms are for the convenience of explanation, and the scope of rights of the present disclosure should not be limited by the above terms.

[0027] In addition, although the integrated components for communication other than the coupling structure of the wireless communication device 100 are omitted in the description of the present invention, a person skilled in the art should be able to easily understand that the present disclosure is an illustration of the wireless communication device 100 .

[0028] Figure 2 is a front view of a wireless communication device according to an embodiment of the present disclosure. Figure 3 is an exploded perspective view of a wireless communication device according to an embodiment of the present disclosure.

[0029] Reference Figure 2 and Figure 3 According to an embodiment of the present disclosure, a wireless communication device 100 may include a radome 110 , a lower box body 130 , and a fastener 150 .

[0030] The radome 110 is disposed above the wireless communication device 100 and has a structure that is a complete component that protects the wireless communication device 100 from the external environment.

[0031] The radome 110 can be manufactured by cutting during the drawing process. Figure 3 The shape shown in the figure is obtained by performing an initial drawing process on a continuous drawn object. At this time, the drawn object can be an elastically deformable material, such as a synthetic resin such as plastic. Afterwards, the drawn object is cut into a predetermined length. Thus, multiple Figure 2The radome 110 shown in FIG. If the manufacturing equipment as described above is provided, the radome 110 according to an embodiment of the present disclosure has the advantage of a simple manufacturing process. When the radome 110 is manufactured by a drawing process, the radome 110 may be arranged along at least a first direction and open at both ends.

[0032] The radome 110 includes at least one first bending portion 112 , a sealing protrusion 114 and a first buckling portion 115 .

[0033] The first bending portion 112 is formed along a direction parallel to the first direction. Based on the first bending portion 112, at least one end of the antenna cover 110 is directed downward. In addition, although the antenna cover 110 according to this embodiment is shown as including a pair of first bending portions 112 parallel to the first direction, the present disclosure is not necessarily limited thereto, and may also include only one first bending portion 112.

[0034] The sealing protrusion 114 has a structure that can be inserted into the sealing protrusion groove 132 formed in the lower case 130. The sealing protrusion 114 can prevent foreign substances such as water or moisture from entering the interior of the wireless communication device 100. The description of the sealing structure will be given in Figure 4 and Figure 5 Detailed description is given in .

[0035] The first buckle portion 115 is arranged at one end of the antenna cover 110, and at least a portion thereof extends along the first direction. The first buckle portion 115 has a structure that is coupled with at least a portion of the fastener 150 in a buckled manner. According to the present embodiment, although the first buckle portion 115 is formed in a form protruding toward the outside of the wireless communication device 100, it is not necessarily limited thereto, and may be formed in a form facing the inside of the wireless communication device 100. In this case, the first buckle portion 115 may be formed between the inner wall and the outer wall of the antenna cover 110.

[0036] The lower box body 130 has a structure that is combined with the radome 110 and forms a closed accommodation space therein. For example, if at least one side of the radome 110 is open, the lower box body 130 may include a side wall complementarily combined with the open side of the radome 110 .

[0037] In the accommodation space formed by the combination of the lower case 130 and the antenna cover 110, a substrate (not shown) and an antenna module (not shown) for communication may be arranged. Although the lower case 130 may be made of a metal material, it is not necessarily limited thereto.

[0038] The lower box body 130 includes a sealing protrusion groove 132. The sealing protrusion groove 132 has a structure for accommodating at least a portion of the sealing protrusion 114. The sealing protrusion groove 132 is formed along at least one side end of the lower box body 130. Since the sealing protrusion groove 132 is arranged close to the end, when the lower box body 130 and the antenna cover 110 are combined, the combined area does not infringe on the internal accommodation space. Therefore, it has the advantage of high space utilization.

[0039] During the assembly process of the radome 110 and the lower box body 130, the radome 110 can be properly guided when the sealing protrusion 114 is inserted into the sealing protrusion groove 132. In addition, there is no need to align the screw holes as in bolt connection, so there is an advantage of making the assembly process of the radome 110 and the lower box body 130 simple.

[0040] The fastener 150 may have a substantially clip-shaped shape. The fastener 150 includes a radome side snap-on portion 152 (see Figure 4 ) and the box body side buckle portion 154 (refer to Figure 3 ), the antenna cover side snap-in portion 152 is formed on one side of the fastener 150 for combining with the antenna cover 110 side, and the box body side snap-in portion 154 is formed on the other side of the fastener 150 and for combining with the lower box body 130.

[0041] In a state where the radome 110 and the lower case 130 are combined, the fastener 150 is respectively combined with at least a portion of the radome 110 and the lower case 130. Therefore, a greater reinforcement force can be provided when the radome 110 and the lower case 130 are combined.

[0042] In addition, the operator can easily assemble the wireless communication device 100 by inserting the fastener 150, thereby having the effect of improving assembly efficiency.

[0043] The wireless communication device 100 may further include a first sealing member 120 .

[0044] When the sealing protrusion 114 is inserted into the sealing protrusion groove 132 , the first sealing member 120 may be disposed between the sealing protrusion 114 and the sealing protrusion groove 132 .

[0045] The first sealing member 120 has a structure that closely contacts with at least a portion of the sealing protrusion 114 and covers at least a portion of the sealing protrusion 114. Therefore, the inner surface of the first sealing member 120 has a shape corresponding to the outer surface of the sealing protrusion 114.

[0046] At least a portion of the first sealing member 120 is formed of a flexible material, such as silicon. However, the present disclosure is not necessarily limited thereto, and other flexible materials such as rubber may be selected.

[0047] Figure 41 is an enlarged cross-sectional view showing a state where the wireless communication device is longitudinally cut along IV-IV' according to an embodiment of the present disclosure.

[0048] Reference Figure 4 , the combination structure of the antenna cover 110, the lower box body 130 and the fastener 150 is described in detail.

[0049] The radome 110 may include a second bent portion 116 and a third bent portion 118 .

[0050] The second bending portion 116 is disposed between the first bending portion 112 and the first buckling portion 115. Due to the second bending portion 116, a portion of the radome 110 can protrude from an end of a side wall of the radome 110 toward the outside of the wireless communication device 100, specifically toward the side.

[0051] The third bending portion 118 is disposed between the second bending portion 116 and the first buckle portion 115. Based on the third bending portion 118, the protruding end of the radome 110 can protrude upward. A groove can also be formed between the second bending portion 116 and the third bending portion 118.

[0052] The lower case 130 may include a second locking portion 136 and a fastener slot 138 .

[0053] The second buckle portion 136 is arranged at the end of the lower box body 130, and at least a portion thereof extends along the first direction. The first buckle portion 115 has a structure that is coupled to the box body side buckle portion 154 in a buckled manner. According to the present embodiment, although the second buckle portion 136 can be formed in a form protruding toward the outside of the wireless communication device 100, it is not necessarily limited thereto, and can be formed toward the inside of the wireless communication device 100. In this case, the second buckle portion 136 can be formed between the inner wall and the outer wall of the lower box body 130.

[0054] The fastener groove 138 is close to the second locking portion 136 and is formed on at least one surface of the lower box body 130 , and at least a portion thereof extends along the first direction.

[0055] The fastener 150 includes a radome-side snap-in portion 152 and a box-body-side snap-in portion 154 .

[0056] The radome side buckle portion 152 has a structure facing at least a portion of one side of the first buckle portion 115. The radome side buckle portion 152 has at least one bending portion. When the radome side buckle portion 152 includes two or more bending portions, one end of the radome side buckle portion 152 can be arranged in the groove formed between the second bending portion 116 and the third bending portion 118.

[0057] The box body side buckle part 154 has a structure facing at least a part of one side of the second buckle part 136. The box body side buckle part 154 has at least one bending part. When the box body side buckle part 154 includes at least two bending parts, one end of the box body side buckle part 154 can be accommodated in the fastener groove 138.

[0058] Since the antenna cover side snap-in portion 152 and the box body side snap-in portion 154 include at least two bent portions, even if a force is applied to the side of the fastener 150 to release the connection, the antenna cover side snap-in portion 152 can be fixed and not detached from the first snap-in portion 115 .

[0059] The fastener 150 may also include a bend region 156 .

[0060] The bending region 156 may be formed at any one of at least one end of the antenna cover side buckle portion 152 or the box body side buckle portion 154. When the wireless communication device 100 needs to be disassembled, the fastener 150 needs to be separated from the antenna cover 110 and the lower box body 130. At this time, if pressure is applied to a surface formed between the bending region 156 and the end of the fastener 150, the surface in contact with the antenna cover 110 or the lower box body 130 can be separated from the contacting surface. Therefore, the operator can easily remove the fastener 150.

[0061] Figure 5 4 is a front view of a first sealing component according to an embodiment of the present disclosure.

[0062] Reference Figure 4 and Figure 5 , the sealing structure of the wireless communication device 100 according to an embodiment of the present disclosure will be described in detail.

[0063] Reference Figure 4 and Figure 5 The first sealing component 120 may include a sealing body 122 and at least one sealing pin 124 .

[0064] The sealing body 122 has a structure that is in close contact with at least a portion of the sealing protrusion 114 and covers at least a portion of the sealing protrusion 114. The sealing body 122 extends in the direction in which the sealing protrusion 114 extends.

[0065] The sealing pin 124 protrudes from at least one side of the sealing body 122 toward one side of the sealing protrusion groove 132. In addition, the first sealing component 120 may further include at least one sealing pin 124, and the at least one sealing pin 124 protrudes from the other side of the sealing body 122 toward the other side of the sealing protrusion groove 132. At least a portion of the sealing pin 124 extends in the extension direction of the sealing body 122, that is, in a direction parallel to the first direction.

[0066] The first sealing member 120 may include a plurality of sealing pins 124. At this time, the plurality of sealing pins 124 may be separated from each other and arranged in parallel along a height direction of the sealing body 122.

[0067] Due to design reasons, there is a gap between the sealing protrusion 114 and the sealing protrusion groove 132. In this case, there is a possibility that foreign substances, such as water or moisture, etc., flow in through the gap. At this time, since the sealing pin 124 extends along the extending direction of the sealing protrusion 114, it is possible to prevent foreign substances from flowing in from the outside. In addition, if a plurality of sealing pins 124 are arranged in a stacked structure, the waterproof or shockproof effect can be increased.

[0068] The lower box body 130 may also include a sealing pin groove 134 for accommodating the sealing pin 124. The sealing pin groove 134 is formed on at least one side of the sealing protrusion groove 132 in a shape and position corresponding to the sealing pin 124. Thereby, the sealing effect can be increased. Furthermore, a snap-fit ​​structure is formed by the sealing pin 124 and the sealing pin groove 134, thereby increasing the contact area between the sealing pin 124 and the sealing pin groove 134. Based on this, the friction between the first sealing component 120 and the sealing protrusion groove 132 can be increased. Therefore, the fastening force between the antenna cover 110 and the lower box body 130 can be further improved.

[0069] In addition, the wireless communication device 100 may further include a second sealing member 140 .

[0070] When the sealing protrusion 114 is inserted into the sealing protrusion groove 132, the second sealing member 140 may be disposed between the sealing protrusion 114 and the sealing protrusion groove 132. In addition, when the sealing protrusion 114 is tightly combined with the first sealing member 120, the second sealing member 140 may be disposed between the first sealing member 120 and the sealing protrusion groove 132.

[0071] Before the sealing protrusion 114 is inserted into the sealing protrusion groove 132 , the second sealing member 140 may be applied to at least one surface of the sealing protrusion groove 132 .

[0072] Figure 6 is a front view of a wireless communication device according to another embodiment of the present disclosure. Figure 7 is an exploded perspective view of a wireless communication device according to another embodiment of the present disclosure.

[0073] Reference Figure 6 and Figure 7 According to another embodiment of the present disclosure, a wireless communication device 200 may include at least two pairs of first bending portions 212 and a first sealing member 220 formed along ends of each side wall.

[0074] Another pair of first bent portions 212 may be disposed between the pair of first bent portions 212 formed in a direction parallel to the first direction of the radome 210. Thus, four side walls may be formed, which have a structure with ends facing downward.

[0075] Sealing protrusions (not shown) may be formed on the ends of the four side walls along the length direction of each end.

[0076] The lower box body 230 includes a sealing protrusion groove 232 for the sealing protrusion to be inserted.

[0077] The first sealing member 220 may be formed to surround at least a portion of the end of each side wall. In this case, the first sealing member 220 may have a substantially annular structure.

[0078] In a state where the radome 210 and the lower case 230 are combined, the fastener 250 is respectively combined with at least a portion of the radome 210 and the lower case 230. Therefore, a greater reinforcement force can be provided when the radome 210 and the lower case 230 are combined.

[0079] Figure 8 is an enlarged cross-sectional view of an upper housing according to yet another embodiment of the present disclosure.

[0080] Reference Figure 8 According to another embodiment of the present disclosure, a sealing pin 324 may be attached to one side of the sealing protrusion 314. That is, the first sealing member 320 does not include a sealing body.

[0081] At least a portion of the sealing pin 324 extends parallel to the extending direction of the sealing protrusion 314, and a plurality of sealing pins 324 may be arranged separately from each other along the height direction of the sealing protrusion 314. In this case, although the sealing protrusion 314 and the sealing pin 324 may be manufactured in a double injection manner, they are not necessarily limited thereto.
