Description

[Technical Field]

[0001] The present disclosure relates to a vibration damping device for an antenna device, and more particularly to a vibration damping device for a vibration antenna device for seismic design of antenna structures. [Background technology]

[0002] The material described in this section merely provides background information related to the present disclosure and may not constitute prior art.

[0003] Antennas for wireless communication are often installed on rooftops of buildings to improve the quality of wireless signal transmission and reception. In this case, the antenna structure is directly exposed to the weather and climate, so measures are taken to protect the antenna structure from various external factors.

[0004] Meanwhile, in recent years, abnormal weather events due to global warming and other factors have become more frequent around the world, and natural disasters such as earthquakes and typhoons not only cause loss of life but also have a significant impact on the performance of various information and communication facilities.

[0005] On the rooftop of a building, an antenna device is installed and fixed to a solid support, and various reinforcing structures are additionally installed to protect the antenna structure from the above-mentioned external factors. In particular, vibrations caused by earthquakes, typhoons, etc. can reduce the quality of wireless signal transmission and reception and the lifespan of the antenna device, so a method for attenuating such vibrations is required.

[0006] However, most antenna structures have to increase the rigidity of the structure itself or add a separate heavy reinforcing structure to dampen vibrations, which results in excessive weight and increased costs for the entire structure. Summary of the Invention [Problem to be solved by the invention]

[0007] Therefore, the present disclosure is intended to solve such problems, and its main objective is to provide a vibration damping device for an antenna device that can improve the earthquake resistance performance of an antenna structure without excessively increasing its weight. [Means for solving the problem]

[0008] To achieve this object, one embodiment of the present disclosure provides a vibration damping device comprising: a first fixing member having a predetermined thickness and having a first recessed area formed by at least a portion being recessed; a second fixing member having a predetermined thickness, configured to be coupled to the first fixing member, and having a second recessed area formed by at least a portion being recessed; and at least one elastic member disposed between the first fixing member and the second fixing member.

[0009] Furthermore, the present invention provides an antenna apparatus including the at least one vibration damping device, characterized in that the antenna apparatus includes a support fixture coupled to one side of the at least one vibration damping device, and an antenna module coupled to the other side of the at least one vibration damping device. [Effects of the Invention]

[0010] As described above, according to this embodiment, it is possible to improve the earthquake resistance of the antenna structure without excessively increasing its weight. [Brief explanation of the drawings]

[Figure 2]1 is an exploded perspective view of a vibration damping device according to an embodiment of the present disclosure. FIG. [Figure 3] 1 is a top view of a vibration damping device according to an embodiment of the present disclosure. FIG.

[0012] Some embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. When assigning reference numerals to components in each drawing, please note that the same reference numerals are used for the same components even if they appear in different drawings. In describing the present disclosure, if a detailed description of related known structures or functions is deemed to obscure the gist of the present disclosure, such a detailed description will be omitted.

[0013] In describing components of the embodiments of the present disclosure, reference numerals such as 1, 2, i), ii), a), b) may be used. Such reference numerals are used only to distinguish the components from other components, and do not limit the essence or order or sequence of the components. When a part in the specification is said to "include" or "comprise" a certain component, this does not mean that other components are excluded, but that the part may further include other components, unless explicitly stated to the contrary.

[0014] FIG. 1 is an assembly diagram of a vibration damping device according to one embodiment of the present disclosure.

[0015] FIG. 2 is an exploded perspective view of a vibration damping device according to one embodiment of the present disclosure.

[0016] FIG. 3 is a top view of a vibration damping device according to one embodiment of the present disclosure.

[0017] 1 to 3, a vibration reduction apparatus 10 according to one embodiment of the present disclosure includes a first fixing member 100, a second fixing member 200, and all or part of at least one elastic member 300, 320, 340.

[0018] The first fixing member 100 has a predetermined thickness and includes a first recessed area 120 formed by recessing at least a portion of the first fixing member 100. Here, the predetermined thickness means a thickness sufficient to withstand the load of an antenna module (450 in FIG. 4), which will be described later.

[0019] The second fixing member 200 has a predetermined thickness, is configured to be coupled to the first fixing member 100, and includes a second recessed area 220. Here, the thickness of the second fixing member 200 is preferably configured to be the same as the thickness of the first fixing member 100, but is not necessarily limited thereto.

[0020] 2, the first and second depressed regions 120 and 220 are recessed so that their cross sections are rhombic, but are not necessarily limited to this shape. Also, it is preferable that the first and second depressed regions 120 and 220 be configured to have the same shape, but are not necessarily limited to this.

[0021] First recessed region 120 includes a first recessed floor surface 122 formed at one end of the recessed direction. For example, the recessed direction of first recessed region 120 is parallel to the Z axis in FIGS. 1 and 2, but is not necessarily limited thereto.

[0022] Furthermore, second recessed region 220 includes a second recessed floor surface 222 formed at one end of the recessed direction. For example, the recessed direction of second recessed region 220 is parallel to the Z axis in FIGS. 1 and 2, but is not necessarily limited thereto.

[0023] The first fixing member 100 and the second fixing member 200 are coupled together such that the first depressed floor surface 122 and the second depressed floor surface 222 face each other. For example, the second depressed floor surface 222 of the second fixing member 200 is coupled to face the upper part of the first depressed floor surface 122 of the first fixing member 100, and in this case, at least a portion of the second fixing member 200 is coupled to cover at least a portion of the first fixing member 100.

[0024] However, it is not necessary that the second depressed floor surface 222 be connected to face the top of the first depressed floor surface 122; conversely, the first depressed floor surface 122 may be connected to face the top of the second depressed floor surface 222.

[0025] The vibration damping device 10 according to one embodiment of the present disclosure has a multi-layer structure in which at least a portion of either the first fixing member 100 or the second fixing member 200 covers at least a portion of the other fixing member. Therefore, when supporting the antenna module 450 described below, the vibration damping device 10 prevents deflection due to a vertical load on the antenna module 450 itself or a vertical force caused by an earthquake.

[0026] At least one biasing member 300, 320, 340 is disposed between the first fixing member 100 and the second fixing member 200. More particularly, at least one biasing member 300, 320, 340 is disposed within the first recessed area 120 and the second recessed area 220.

[0027] In FIG. 2, at least one of the biasing members 300, 320, 340 is configured with three biasing members, but the number is not necessarily limited to three, and the biasing member may be configured with one or more biasing members.

[0028] Therefore, the vibration damping device 10 according to one embodiment of the present disclosure can support the antenna module 450 while at the same time at least one of the biasing members 300, 320, 340 can act as a damper, so that a separate reinforcing structure for the earthquake-resistant design of the antenna device is not required.

[0029] Meanwhile, the first fixing member 100 and the second fixing member 200 are connected by a screw 150. In this case, the screw 150 can pass through the center of the first recessed floor surface 122 and the second recessed floor surface 222, thereby connecting the first fixing member 100 and the second fixing member 200.

[0030] Referring again to FIG. 2, the first fixing member 100 includes a first opening 125 penetrating the first recessed floor surface 122 in a direction parallel to the Z-axis direction, and the second fixing member 200 includes a coupling hole 225 that is closed on one side and extends in a direction parallel to the Z-axis direction.

[0031] Here, at least a portion of the coupling hole 225 is inserted into and fixed within the first opening 125, and the screw 150 is coupled to the coupling hole 225, thereby coupling the first fixing member 100 and the second fixing member 200.

[0032] However, the first opening 125 and the connecting hole 225 do not necessarily have to be included in the first fixing member 100 and the second fixing member 200, respectively, and it is also possible for the first fixing member 100 to be configured to include the connecting hole 225 and the second fixing member 200 to be configured to include the first opening 125.

[0033] Meanwhile, the first fixing member 100 is formed symmetrically with respect to a first reference surface (not shown) perpendicular to the first depressed floor surface 122, and the second fixing member 200 is formed symmetrically with respect to a second reference surface (not shown) perpendicular to the second depressed floor surface 222.

[0034] Although the first and second reference planes are not shown in the drawings, when referring to Figures 1 and 2, the plane parallel to the YZ plane and passing through the center of the first depressed floor surface 122 is the first reference plane, and the plane parallel to the YZ plane and passing through the center of the second depressed floor surface 222 is the second reference plane.

[0035] The first reference plane and the second reference plane are identical, and at least one biasing member 300, 320, 340 is configured to provide a restoring force to the first fixing member 200 and the second fixing member when a torque is applied about a central axis 250 that is perpendicular to the first recessed floor surface 122 and is included in the first reference plane.

[0036] That is, the vibration damping device 10 according to an embodiment of the present disclosure is restored to its initial state even when a rotational torque due to an earthquake or the like is applied, thereby enabling an efficient earthquake-resistant design of the antenna device.

[0037] The manner in which the at least one biasing member 300, 320, 340 provides the restoring force is described below.

[0038] The first recessed region 120 includes a first recessed wall 124 formed in a direction protruding from a first recessed floor 122. In this case, the first recessed wall 124 is perpendicular to the first recessed floor 122, but is not necessarily limited thereto.

[0039] The second recessed region 220 includes a second recessed wall 224 formed in a direction protruding from the second recessed floor 222. In this case, the second recessed wall 224 is perpendicular to the second recessed floor 222, but this is not necessarily limited to this.

[0040] Additionally, the at least one biasing member 300 , 320 , 340 includes a first elastic member 300 and a second elastic member 320 .

[0041] In this case, the first biasing member 300 has a shape corresponding to the first recessed wall 124 and is disposed so as to abut against at least a portion of the second fixing member 200 and the first recessed wall 124. The second biasing member 320 has a shape corresponding to the second recessed wall 224 and is disposed so as to abut against at least a portion of the first fixing member 100 and the second recessed wall 224.

[0042] Therefore, the first biasing member 300 can provide a restoring force to the first fixing member 100 and the second fixing member 200 by being compressed or pulled between the first recessed wall 124 and at least a portion of the second fixing member 200, and the second biasing member 320 can provide a restoring force to the first fixing member 100 and the second fixing member 200 by being compressed or pulled between the second recessed wall 224 and at least a portion of the first fixing member 100.

[0043] A more effective earthquake-resistant design is possible because both the first biasing member 300 and the second biasing member 320 can provide a restoring force to the first fixing member 100 and the second fixing member 200. However, the at least one biasing member 300, 320, 340 does not necessarily have to include the first biasing member 300 and the second biasing member 320, and it is also possible to include only one of the first biasing member 300 and the second biasing member 320.

[0044] Meanwhile, the first recessed wall 124 may be concave or convex about a first reference plane, and the second recessed wall 224 may be concave or convex about a second reference plane. When the first reference plane and the second reference plane are the same, the first recessed wall 124 and the second recessed wall 224 are formed symmetrically about the same reference plane.

[0045] In this case, the first biasing member 300 and the second biasing member 320 are also formed symmetrically about the same reference plane. For example, the first biasing member 300 and the second biasing member 320 are also configured to be concave or convex about the same reference plane. Therefore, when a rotational torque is applied about the central axis 250, the first biasing member 300 and the second biasing member 320 can efficiently provide a restoring force to the first fixing member 100 and the second fixing member 200.

[0046] However, the first recessed wall 124 and the first biasing member 300 do not necessarily have to have a concave or convex shape centered on the first reference plane, and there are no limitations on their shapes as long as they can provide a restoring force to the first fixing member 100 and the second fixing member 200 when a rotational torque is applied about the central axis 250. The same applies to the second recessed wall 224 and the second biasing member 320.

[0047] At least one biasing member 300, 320, 340 may include a third elastic member 340 disposed between first recessed area 120 and second recessed area 220. More particularly, for example, at least one biasing member 300, 320, 340 is disposed between first recessed floor surface 122 and second recessed floor surface 222.

[0048] The third biasing member 340 also includes at least one protruding portion 342, 344, 346, 348 protruding from one surface of the third biasing member 340.

[0049] The third biasing member 340 also serves to provide a restoring force to the first fixing member 100 and the second fixing member 200 in the same manner as the first biasing member 300 and the second biasing member 320 .

[0050] The third biasing member 340 also includes a second opening 345 that penetrates the third biasing member 340 in a direction parallel to the Z-axis direction for threaded coupling of the first fixing member 100 and the second fixing member 200. In this case, it is preferable that the center of the second opening 345 is configured to coincide with the center of the first opening 125.

[0051] On the other hand, in FIG. 2, at least one biasing member 300, 320, 340 is configured to be formed with a separate configuration before the first fixing member 100 and the second fixing member 200 are joined, but this is not necessarily limited to this.

[0052] For example, the first fixing member 100 and / or the second fixing member 200 includes a penetration injection hole 350 formed through at least one surface, and at least one of the biasing members 300, 320, 340 is formed using a liquid phase injected through the penetration injection hole 350.

[0053] In this case, at least one of the biasing members 300, 320, 340 is formed by hardening a liquid phase injected into the space between the first fixing member 100 and the second fixing member 200 after the first fixing member 100 and the second fixing member 200 are bonded together.

[0054] 1 and 3, a method of providing a restoring force of the first biasing member 300 will be described below. The method of providing a restoring force of the first biasing member 300 described below is similarly applied to the second biasing member 320.

[0055] When a rotational torque about the central axis 250 acts on the vibration damping device 10 according to an embodiment of the present disclosure, one side of the first biasing member 300 is compressed and the other side is pulled relative to the central axis 250. For example, in FIG. 3 , one end of the first biasing member 300 in the positive X-axis direction is compressed, and one end of the first biasing member 300 in the negative X-axis direction is pulled.

[0056] This generates a restoring force that causes the first biasing member 300 to return to its original shape, and this torque is in the opposite direction to the rotational torque applied to the vibration damping device 10 according to an embodiment of the present disclosure. This restoring force is transmitted to the first fixed member 100 and the second fixed member 200, and the vibration damping device 10 according to an embodiment of the present disclosure can maintain its original shape and effectively damp external vibrations.

[0057] On the other hand, although not shown in the drawings, the third biasing member 340 also provides a restoring force to the first fixed member 100 and the second fixed member 200 as a torque in the opposite direction to the rotational torque applied to the vibration damping device 10 according to one embodiment of the present disclosure.

[0058] 2, the third biasing member 340 is disc-shaped. Further, for example, the at least one protrusion 342, 344, 346, 348 includes at least one vertical protrusion portion 342, 344 and / or at least one horizontal protrusion portion 346, 348.

[0059] In this case, at least one vertical protrusion 342, 344 is configured to protrude in the thickness direction from the upper or lower surface of the disk-shaped third biasing member 340, and at least one horizontal protrusion 346, 348 is configured to protrude in a direction perpendicular to the thickness direction from one side of the disk-shaped third biasing member 340.

[0060] Meanwhile, as shown in FIG. 2, at least one vertical protrusion 342, 344 and at least one horizontal protrusion 346, 348 are each composed of two, and the four protrusions are arranged at 90-degree intervals, but the number and spacing of the protrusions are not necessarily limited to this.

[0061] When a rotational torque about the central axis 250 acts on the vibration damping device 10 according to one embodiment of the present disclosure, the third biasing member 340 can provide a restoring force to the first fixed member 100 and the second fixed member 200 through at least one protrusion 342, 344, 346, 348.

[0062] FIG. 4 is a diagram illustrating a portion of an antenna device according to an embodiment of the present disclosure.

[0063] Referring to FIG. 4, an antenna apparatus 40 according to one embodiment of the present disclosure includes a support fixture 400, an antenna module 450, and all or part of at least one vibration damping device 10.

[0064] Here, a support 400 is coupled to one side of at least one vibration damping device 10, and an antenna module 450 is coupled to the other side thereof. Therefore, the antenna module 450 is coupled to the support 400 by at least one vibration damping device 10, and thus the antenna device 40 according to an embodiment of the present disclosure can also have a vibration-resistant function as described above.

[0065] Furthermore, the antenna device 40 according to an embodiment of the present disclosure includes two vibration damping devices 10, which are arranged on the upper and lower parts of the antenna module 450. In this case, the two vibration damping devices 10 are arranged so that the same surfaces of the two vibration damping devices 10 face each other in a direction parallel to the height direction of the support base 400.

[0066] That is, the two vibration damping devices 10 are arranged such that one vibration damping device is upside down relative to the other, thereby ensuring robust support and durability.

[0067] The above description merely exemplifies the technical concept of the present embodiment, and various modifications and variations may be made by a person skilled in the art without departing from the essential characteristics of the present embodiment. Therefore, the present embodiment is intended to illustrate, not limit, the technical concept of the present embodiment, and the scope of the technical concept of the present embodiment is not limited by such an embodiment. The scope of protection of the present embodiment should be interpreted by the claims, and all technical concepts within the scope equivalent thereto should be interpreted as being included in the scope of the present embodiment.
