Description

Technical Field

[0001] The present disclosure relates to a vibration damping device for an antenna device. More specifically, it relates to a damping device for a vibration antenna device for the seismic design of an antenna structure.

Background Art

[0002] The content described in this part merely provides background information related to the present disclosure and does not constitute the prior art.

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

[0004] On the other hand, in recent years, abnormal climates due to global warming, etc. have become increasingly frequent worldwide. For example, natural disasters such as earthquakes and typhoons not only cause casualties but also have a significant impact on the performance of various information and communication facilities.

[0005] On the rooftop of a building, etc., the antenna device will be installed and fixed on a sturdy support base, and various reinforcing structures will be additionally installed to protect the antenna structure from the aforementioned external factors. In particular, vibrations caused by earthquakes and typhoons, etc. cause a decline in the quality of wireless signal transmission and reception and the lifespan of the antenna device, so a solution for attenuating such vibrations is necessary.

[0006] However, most antenna structures use a method of increasing the rigidity of the structure itself or adding a separate heavy reinforcing structure for vibration attenuation, and there is a problem that the weight of the entire structure is excessively increased and the cost also rises.

Summary of the Invention

Problems to be Solved by the Invention

[0008] According to one embodiment of the present disclosure for achieving such objectives, a vibration damping device is provided, comprising: a first fixing member having a predetermined thickness and a first recessed area formed by at least a portion of it being recessed; a second fixing member having a predetermined thickness and configured to be coupled with the first fixing member, and a second recessed area formed by at least a portion of it 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 a vibration damping device comprising, in an antenna apparatus including at least one vibration damping device, 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 explained above, this embodiment has the effect of improving the seismic resistance of the antenna structure without an excessive increase in weight. [Brief explanation of the drawing]

[0011] [Figure 1] This is a coupling diagram of a vibration damping device according to one embodiment of the present disclosure. [Figure 2]This is an exploded perspective view of a vibration damping device according to one embodiment of the present disclosure. [Figure 3] This is a top view of a vibration damping device according to one embodiment of the present disclosure. [Figure 4] This figure illustrates a part of an antenna device according to one embodiment of the present disclosure. [Modes for carrying out the invention]

[0012] Hereinafter, some embodiments of this disclosure will be described in detail using illustrative drawings. Note that when assigning reference numerals to components in each drawing, efforts have been made to ensure that identical components have the same reference numeral whenever possible, even when shown in different drawings. Furthermore, in describing this disclosure, if a specific description of a related known configuration or function is deemed to obscure the gist of this disclosure, such detailed description will be omitted.

[0013] In describing the components of the embodiments described herein, reference numerals such as 1st, 2nd, i), ii), a), b), etc. may be used. Such reference numerals are used solely to distinguish a component from other components, and do not limit the nature, order, or sequence of the component in question. When a part of the specification says that it "includes" or "companies" a component, this means that, unless explicitly stated otherwise, it may include other components rather than excluding them.

[0014] Figure 1 is a coupling diagram of a vibration damping device according to one embodiment of the present disclosure.

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

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

[0017] Referring to Figures 1 to 3, a vibration reduction apparatus 10 according to one embodiment of the present disclosure includes all or part of a first fixing member 100, a second fixing member 200, and 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 it. Here, the predetermined thickness means a sufficient thickness to withstand the load of the antenna module (450 in Figure 4), which will be described later.

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

[0020] On the other hand, in Figure 2, the first depression region 120 and the second depression region 220 are depressions that form a rhombus shape in cross-section, but the shape is not necessarily limited to this. Furthermore, it is preferable that the first depression region 120 and the second depression region 220 are configured to have the same shape, but the shape is not necessarily limited to this.

[0021] The first recessed area 120 includes a first recessed floor surface 122 formed at one end in the direction of recession. For example, the direction in which the first recessed area 120 is recessed is parallel to the Z-axis in Figures 1 and 2, but is not necessarily limited to this.

[0022] Furthermore, the second recessed area 220 includes a second recessed floor surface 222 formed at one end in the recessed direction. For example, the recessed direction of the second recessed area 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 such that the first recessed floor surface 122 and the second recessed floor surface 222 face each other. For example, the second recessed floor surface 222 of the second fixing member 200 is coupled to face the upper part of the first recessed floor surface 122 of the first fixing member 100. In this case, at least a part of the second fixing member 200 is coupled in a manner that covers at least a part of the first fixing member 100.

[0024] However, it is not necessarily required that the second recessed floor surface 222 be coupled to face the upper part of the first recessed floor surface 122. Conversely, the first recessed floor surface 122 may be coupled to face the upper part of the second recessed floor surface 222.

[0025] The vibration damping device 10 according to an embodiment of the present disclosure is configured such that at least a part of one of the first fixing member 100 and the second fixing member 200 covers at least a part of the other fixing member, and has a multilayer structure. Therefore, when supporting the antenna module 450 described later, the vibration damping device 10 prevents bending from occurring due to the vertical load of the antenna module 450 itself or the vertical force due to 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 specifically, at least one biasing member 300, 320, 340 is disposed within the first recessed area 120 and the second recessed area 220.

[0027] In Figure 2, the system consists of three biasing members 300, 320, and 340, but it is not necessarily limited to three biasing members; it may consist of 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, and at the same time, at least one biasing member 300, 320, 340 can act as a damper, thus eliminating the need for a separate reinforcing structure for the seismic design of the antenna device.

[0029] On the other hand, the first fixing member 100 and the second fixing member 200 are joined by a screw 150. In this case, the screw 150 can pass through the centers of the first recessed floor surface 122 and the second recessed floor surface 222, thereby joining the first fixing member 100 and the second fixing member 200.

[0030] Referring again to Figure 2, the first fixing member 100 includes a first opening 125 that penetrates 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 inside the first opening 125, and the screw 150 is coupled to the coupling hole 225, thereby connecting 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. It is also possible for the first fixing member 100 to include the connecting hole 225 and the second fixing member 200 to include the first opening 125.

[0033] On the other hand, the first fixing member 100 is formed symmetrically with respect to a first reference surface (not shown) perpendicular to the first subsided 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 subsided floor surface 222.

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

[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 subsided floor surface 122 and included in the first reference plane.

[0036] In other words, the vibration damping device 10 according to one embodiment of the present disclosure is restored to its initial state even when rotational torque is applied due to an earthquake or the like, thus enabling efficient seismic design of the antenna device.

[0037] A method in which at least one biasing member 300, 320, or 340 provides a restoring force will be described later.

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

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

[0040] Furthermore, at least one biasing member 300, 320, 340 includes a first biasing member (first elastic member) 300 and a second biasing member (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 positioned to contact 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 positioned to contact 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] Since both the first biasing member 300 and the second biasing member 320 can provide restoring force to the first fixing member 100 and the second fixing member 200, a more effective seismic design is possible. However, at least one of the biasing members 300, 320, 340 does not necessarily have to include both the first biasing member 300 and the second biasing member 320; it is also possible to include only one of the biasing members, either the first biasing member 300 or the second biasing member 320.

[0044] On the other hand, the first recessed wall 124 may be concave or convex with respect to the first reference plane, and the second recessed wall 224 may be concave or convex with respect to the 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 with respect to the same reference plane.

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

[0046] However, the first recessed wall 124 and the first biasing member 300 do not necessarily have to be concave or convex in shape with respect to the first reference plane. As long as they can provide a restoring force to the first fixed member 100 and the second fixed member 200 when rotational torque is applied around the central axis 250, there are no restrictions on their shape. 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 biasing member 340 positioned between the first recessed area 120 and the second recessed area 220. More specifically, for example, at least one biasing member 300, 320, 340 is positioned between the first recessed floor surface 122 and the second recessed floor surface 222.

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

[0049] The third biasing member 340, like the first biasing member 300 and the second biasing member 320, also plays a role in providing a restoring force to the first fixing member 100 and the second fixing member 200.

[0050] Furthermore, the third biasing member 340 includes a second opening 345 that penetrates the third biasing member 340 in a direction parallel to the Z-axis direction for screw connection 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 coincides with the center of the first opening 125.

[0051] On the other hand, in Figure 2, at least one biasing member 300, 320, and 340 are formed separately before the first fixing member 100 and the second fixing member 200 are joined together, but the design is not necessarily limited to this.

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

[0053] In this case, at least one biasing member 300, 320, 340 is formed by the hardening of 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 have been joined together.

[0054] The method of providing restoring force for the first biasing member 300 will be described below with reference to Figures 1 and 3. The method of providing restoring force for the first biasing member 300, as described later, is also applied to the second biasing member 320.

[0055] When a rotational torque centered on the central axis 250 acts on the vibration damping device 10 according to one embodiment of the present disclosure, one side of the first biasing member 300 is compressed and the other side is pulled with respect to the central axis 250. For example, in Figure 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, which is 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. Such a restoring force is transmitted to the first fixed member 100 and the second fixed member 200, so that the vibration damping device 10 according to one embodiment of the present disclosure can maintain its original shape and effectively dampen 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] Referring again to Figure 2, the third biasing member 340 has a disc shape. Furthermore, for example, 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 projection 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 projection 346, 348 is configured to protrude perpendicular to the thickness direction from one side surface of the disk-shaped third biasing member 340.

[0060] On the other hand, as shown in Figure 2, at least one vertical projection 342, 344 and at least one horizontal projection 346, 348 are each composed of two, and the four projections are arranged at 90-degree intervals, but the number and spacing of the projections 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 fixing member 100 and the second fixing member 200 by at least one projection 342, 344, 346, 348.

[0062] Figure 4 is a diagram illustrating a part of an antenna device according to one embodiment of the present disclosure.

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

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

[0065] Furthermore, the antenna device 40 according to one embodiment of the present disclosure includes two vibration damping devices 10, which are located 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 faces of each other face each other in a direction parallel to the height direction of the support base 400.

[0066] In other words, the two vibration damping devices 10 are arranged in such a way that one vibration damping device is inverted above the other, thereby ensuring robust support and durability.

[0067] The above description is merely illustrative of the technical concept of this embodiment, and any person with ordinary skill in the art to which this embodiment belongs could make various modifications and variations without departing from the essential characteristics of this embodiment. Therefore, this embodiment is for illustrative purposes only, not to limit the technical concept of this embodiment, and the scope of the technical concept of this embodiment is not limited by such embodiment. The scope of protection of this embodiment should be interpreted by the claims, and all technical concepts within an equivalent scope should be interpreted as being included in the scope of rights of this embodiment.
