Abstract
Description
Technical Field
[0001] The present disclosure relates to a shock-absorbing device for an antenna device. More specifically, it relates to a shock-absorbing device for an antenna device for seismic design of an antenna structure. Background Art
[0002] The content described in this section is only used to provide background information for the present utility model and does not constitute prior art.
[0003] Antennas for wireless communication are often installed on the rooftops of buildings to improve the quality of wireless signal transmission and reception, etc. In such cases, since the antenna structure is directly exposed to the environment such as climate and weather, measures are usually taken to protect the antenna structure from being damaged by various external factors.
[0004] In addition, recently, due to the greenhouse effect of the earth, etc., extreme climates occur frequently. Natural disasters such as earthquakes and typhoons not only cause personal injuries but also have a significant impact on the performance of various information and communication facilities.
[0005] On the rooftops of buildings, etc., the antenna device is usually installed and fixed on a firm support platform. As described above, in order to protect the antenna structure from being damaged by external factors, various reinforcement structures will be additionally installed. In particular, vibrations caused by earthquakes and typhoons, etc., will reduce the quality of wireless signal transmission and reception and the lifespan of the antenna device. Therefore, a solution for attenuating such vibrations is urgently needed.
[0006] However, in most antenna structures, in order to achieve shock absorption, methods such as increasing the strength of the structure itself or adding additional heavy object reinforcement structures are adopted, which will lead to problems of excessive increase in the overall weight of the structure and rising costs. Summary of the Invention
[0007] (I) Technical Problems to be Solved
[0008] Therefore, in order to solve the above problems, the purpose of the present disclosure is to provide a shock-absorbing device for an antenna device that can improve the seismic performance of the antenna structure without excessive weight increase.
[0009] (II) Technical Solutions
[0010] To achieve the above object, according to an embodiment of the present disclosure, a shock absorption device is provided, including: a first fixing member having a predetermined thickness and having a first recessed area formed by at least a part thereof being sunken; a second fixing member having a predetermined thickness and capable of being combined with the first fixing member, having a second recessed area formed by at least a part thereof being sunken; and at least one elastic member disposed between the first fixing member and the second fixing member.
[0011] In addition, an antenna apparatus having at least one shock absorption device is provided. The antenna apparatus includes: a support fixture combined on one side of the at least one shock absorption device; and an antenna module combined on the other side of the at least one shock absorption device.

[0017] Figure 4 is a view showing a part of an antenna apparatus according to an embodiment of the present disclosure. Detailed Description of the Embodiment
[0018] Hereinafter, some embodiments of the present disclosure will be described in detail with reference to the drawings. When labeling the reference numerals in the respective drawings, even if the same constituent elements appear in different drawings, the same reference numerals are used as much as possible. Throughout the specification, if a detailed description of related known constituent elements and functions is considered likely to obscure the subject matter of the present disclosure, its detailed description is omitted.
[0019] In the process of describing the components according to embodiments of the present disclosure, symbols such as first, second, i), ii), a), b), etc. may be used. Such symbols are only used to distinguish components from other components, and do not limit the essence, order, or sequence of the corresponding components based on such symbols. Throughout the specification, if a component "includes" or "has" another component, unless there is a particularly contrary record, it can be understood that a component further includes another component, rather than understanding that a component excludes another component.
[0020] Figure 1 is an assembly diagram of a vibration reduction apparatus according to an embodiment of the present disclosure.
[0021] Figure 2 is an exploded perspective view of a vibration reduction apparatus according to an embodiment of the present disclosure.
[0022] Figure 3 is a top view of a vibration reduction apparatus according to an embodiment of the present disclosure.
[0023] Referring to Figures 1 to 3 , a vibration reduction apparatus 10 according to an 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.
[0024] The first fixing member 100 has a predetermined thickness and may have a first recessed area 120 formed by at least a part thereof being sunken. Among them, the predetermined thickness may refer to a thickness that can sufficiently withstand the load of the antenna module ( Figure 4 450) described later.
[0025] The second fixing member 200 has a predetermined thickness and can be combined with the first fixing member 100, and has a second recessed area 220. Among them, the thickness of the second fixing member 200 is preferably set to be the same as the thickness of the first fixing member 100, but is not limited thereto.
[0026] In addition, Figure 2 in the first recessed area 120 and the second recessed area 220 are sunken with an end face in a rhombus shape, but are not limited to the said shape. In addition, the first recessed area 120 and the second recessed area 220 are preferably formed in the same shape, but are not limited thereto.
[0027] The first recessed area 120 may include a first recessed floor surface 122 formed at one end in the recessed direction. For example, the recessed direction of the first recessed area 120 may be parallel to Figure 1 and Figure 2 the Z-axis direction shown, but is not limited thereto.
[0028] In addition, the second recessed area 220 may include 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 may be parallel to Figure 1 and Figure 2 the Z-axis direction shown, but is not limited thereto.
[0029] The first fixing member 100 and the second fixing member 200 can be combined such that the first recessed floor surface 122 and the second recessed floor surface 222 face each other. For example, they can be combined in such a form that the second recessed floor surface 222 of the second fixing member 200 faces the upper part of the first recessed floor surface 122 of the first fixing member 100. In this case, they can be combined in such a way that at least a part of the second fixing member 200 covers at least a part of the first fixing member 100.
[0030] However, it is not limited to being combined in the form that the second recessed floor surface 222 faces the upper part of the first recessed floor surface 122. On the contrary, they can also be combined in the form that the first recessed floor surface 122 faces the upper part of the second recessed floor surface 222.
[0031] According to an embodiment of the present disclosure, the shock-absorbing device 10 can have a multi-layer structure by covering at least a part of one of the first fixing member 100 and the second fixing member 200 with at least a part of the other fixing member. Therefore, during the process of supporting the antenna module 450 described later, it is possible to prevent the shock-absorbing device 10 from sagging due to the vertical load of the antenna module 450 itself or the vertical force generated by an earthquake.
[0032] At least one elastic member 300, 320, 340 may be disposed between the first fixing member 100 and the second fixing member 200. More specifically, at least one elastic member 300, 320, 340 may be disposed within the first recessed area 120 and within the second recessed area 220.
[0033] Figure 2 Among them, at least one of the elastic members 300, 320, 340 is composed of three, but is not limited to being composed of three elastic members, and may be composed of one or more elastic members.
[0034] Therefore, in the shock absorption device 10 according to an embodiment of the present disclosure, since at least one elastic member 300, 320, 340 can support the antenna module 450 while acting as a damper, no additional reinforcing structure is required in the seismic design of the antenna device.
[0035] In addition, the first fixing member 100 and the second fixing member 200 can be coupled 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 coupling the first fixing member 100 and the second fixing member 200.
[0036] Referring back 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 may include a coupling hole 225 that is closed on one side and extends along a direction parallel to the Z-axis direction.
[0037] Among them, at least a part of the coupling hole 225 can be inserted into the inside of the first opening 125 for fixation, and the screw 150 is coupled to the coupling hole 225 to realize the coupling of the first fixing member 100 and the second fixing member 200.
[0038] However, the first opening 125 and the coupling hole 225 do not have to be included in both the first fixing member 100 and the second fixing member 200. It is possible that the first fixing member 100 includes the coupling hole 225 and the second fixing member 200 includes the first opening 125.
[0039] In addition, the first fixing member 100 is symmetrically formed with reference to a first reference surface (not shown) perpendicular to the first recessed floor surface 122, and the second fixing member 200 can be symmetrically formed with reference to a second reference surface (not shown) perpendicular to the second recessed floor surface 222.
[0040] Although the first reference surface and the second reference surface are not shown, when referring to Figure 1 and Figure 2 , the plane parallel to the YZ plane and passing through the center of the first recessed floor surface 122 can be the first reference surface, and the plane parallel to the YZ plane and passing through the center of the second recessed floor surface 222 can be the second reference surface.
[0041] The first reference plane and the second reference plane can be the same one, and at least one of the elastic members 300, 320, 340 is arranged to provide a restoring force to the first fixing member 100 and the second fixing member 200 when a torque centered on the central axis 250 perpendicular to the first recessed floor surface 122 and included in the first reference plane is applied.
[0042] That is, the shock absorption device 10 according to an embodiment of the present disclosure can return to the initial state even when a torque is applied due to an earthquake or the like, so that an effective earthquake-resistant design of the antenna device can be achieved.
[0043] The manner in which at least one of the elastic members 300, 320, 340 provides the restoring force will be described later.
[0044] The first recessed area 120 may include a first recessed wall 124 formed in a protruding direction from the first recessed floor surface 122. In this case, the first recessed wall 124 may be perpendicular to the first recessed floor surface 122, but is not limited thereto.
[0045] The second recessed area 220 may include a second recessed wall 224 formed in a protruding direction from the second recessed floor surface 222. In this case, the second recessed wall 224 may be perpendicular to the second recessed floor surface 222, but is not limited thereto.
[0046] In addition, at least one of the elastic members 300, 320, 340 may include a first elastic member 300 and a second elastic member 320.
[0047] In this case, the first elastic member 300 is formed in a shape corresponding to the first recessed wall 124 and may be arranged to contact at least a part of the second fixing member 200 and the first recessed wall 124. The second elastic member 320 is formed in a shape corresponding to the second recessed wall 224 and may be arranged to contact at least a part of the first fixing member 100 and the second recessed wall 224.
[0048] Therefore, the first elastic member 300 can provide a restoring force to the first fixing member 100 and the second fixing member 200 based on compression or tension between the first recessed wall 124 and at least a part of the second fixing member 200, and the second elastic member 320 can provide a restoring force to the first fixing member 100 and the second fixing member 200 based on compression or tension between the second recessed wall 224 and at least a part of the first fixing member 100.
[0049] Both the first elastic member 300 and the second elastic member 320 can provide a restoring force to the first fixing member 100 and the second fixing member 200, so a more effective seismic design can be achieved. However, at least one of the elastic members 300, 320, 340 is not limited to including the first elastic member 300 and the second elastic member 320, and may also include only any one of the first elastic member 300 and the second elastic member 320.
[0050] In addition, the first recessed wall 124 can be concave or convex with the first reference plane as the center, and the second recessed wall 224 can be concave or convex with the second reference plane as the center. When the first reference plane and the second reference plane are the same plane, the first recessed wall 124 and the second recessed wall 224 can be symmetrically formed with the same reference plane as the center.
[0051] In this case, the first elastic member 300 and the second elastic member 320 can also be symmetrically formed with the same reference plane as the center. For example, the first elastic member 300 and the second elastic member 320 can also be formed concave or convex with the same reference plane as the center. Therefore, when a torque is applied about the central axis 250, the first elastic member 300 and the second elastic member 320 can effectively provide a restoring force to the first fixing member 100 and the second fixing member 200.
[0052] However, the first recessed wall 124 and the first elastic member 300 are not limited to being concave or convex with the first reference plane as the center, and as long as they can provide a restoring force to the first fixing member 100 and the second fixing member 200 when a torque about the central axis 250 is applied, their shapes are not restricted. This also applies to the case of the second recessed wall 224 and the second elastic member 320.
[0053] At least one of the elastic members 300, 320, 340 may further include a third elastic member 340 disposed between the first recessed area 120 and the second recessed area 220. More specifically, for example, at least one of the elastic members 300, 320, 340 may be disposed between the first recessed floor surface 122 and the second recessed floor surface 222.
[0054] In addition, the third elastic member 340 may include at least one protruding portion 342, 344, 346, 348 protruding from one surface of the third elastic member 340.
[0055] The third elastic member 340, like the first elastic member 300 and the second elastic member 320, also serves to provide a restoring force to the first fixing member 100 and the second fixing member 200.
[0056] In addition, the third elastic member 340 may include a second opening 345 that penetrates the third elastic member 340 in a direction parallel to the Z-axis direction to screw-couple the first fixing member 100 and the second fixing member 200. In this case, the center of the second opening 345 is preferably set to coincide with the center of the first opening 125.
[0057] In addition, Figure 2 at least one of the elastic members 300, 320, 340 is set to be pre-formed as individual independent components before the first fixing member 100 and the second fixing member 200 are combined, but is not limited thereto.
[0058] For example, the first fixing member 100 and / or the second fixing member 200 may include a penetration injection hole 350 formed through at least one surface, and at least one of the elastic members 300, 320, 340 may be formed using a liquid injected through the penetration injection hole 350.
[0059] In this case, at least one of the elastic members 300, 320, 340 may be formed by curing as the liquid injected into the space between the first fixing member 100 and the second fixing member 200 solidifies after the first fixing member 100 and the second fixing member 200 are combined.
[0060] Next, with reference to Figure 1 and Figure 3 , the manner of providing the restoring force of the first elastic member 300 will be described. The manner of providing the restoring force of the first elastic member 300 described below is equally applicable to the case of the second elastic member 320.
[0061] When a torque about the central axis 250 acts on the shock absorber 10 according to an embodiment of the present disclosure, one side of the first elastic member 300 may be compressed and the other side may be stretched with respect to the central axis 250. For example, Figure 3 one end portion of the first elastic member 300 in the positive X-axis direction is compressed, and one end portion of the first elastic member 300 in the negative X-axis direction may be stretched.
[0062] Accordingly, the first elastic member 300 can generate a restoring force to return to its original shape, which is a moment opposite to the torque acting on the shock absorption device 10 according to an embodiment of the present disclosure. This restoring force is transmitted to the first fixing member 100 and the second fixing member 200, so that the shock absorption device 10 according to an embodiment of the present disclosure can maintain its original shape while effectively attenuating external vibrations.
[0063] In addition, although not shown in the drawings, the third elastic member 340 also provides a moment opposite to the torque acting on the shock absorption device 10 according to an embodiment of the present disclosure, so as to provide a restoring force to the first fixing member 100 and the second fixing member 200.
[0064] Referring back to Figure 2 , the third elastic member 340 can be formed in a disc shape. In addition, for example, at least one of the protrusions 342, 344, 346, 348 may include at least one vertical protrusion portion 342, 344 and / or at least one horizontal protrusion portion 346, 348.
[0065] In this case, at least one of the vertical protrusion portions 342, 344 can be formed to protrude in the thickness direction from the upper or lower surface of the disc-shaped third elastic member 340, and at least one of the horizontal protrusion portions 346, 348 can be formed to protrude in a direction perpendicular to the thickness direction from one side surface of the disc-shaped third elastic member 340.
[0066] In addition, as Figure 2 shown, at least one of the vertical protrusion portions 342, 344 and at least one of the horizontal protrusion portions 346, 348 are each composed of two, and the four protrusions can be arranged at an angle of 90 degrees, but the number and angle of the protrusions are not limited thereto.
[0067] When a torque about the central axis 250 acts on the shock absorption device 10 according to an embodiment of the present disclosure, the third elastic member 340 can provide a restoring force to the first fixing member 100 and the second fixing member 200 through at least one of the protrusions 342, 344, 346, 348.
[0068] Figure 4 is a diagram of a part of an antenna device according to an embodiment of the present disclosure.
[0069] Referring to Figure 4, according to an embodiment of the present disclosure, an antenna apparatus 40 may include all or part of a support fixture 400, an antenna module 450, and at least one shock-absorbing device 10.
[0070] Among them, one side of at least one shock-absorbing device 10 may be coupled to the support fixture 400, and the other side may be coupled to the antenna module 450. Therefore, the antenna module 450 may be coupled to the support fixture 400 through at least one shock-absorbing device 10, so that the antenna apparatus 40 according to an embodiment of the present disclosure may also have the seismic resistance function as described above.
[0071] In addition, the antenna apparatus 40 according to an embodiment of the present disclosure may include two shock-absorbing devices 10, and the two shock-absorbing devices 10 may be arranged at the upper and lower parts of the antenna module 450. In this case, the two shock-absorbing devices 10 can be arranged such that the same surfaces face each other in a direction parallel to the height direction of the support fixture 400.
[0072] That is, the two shock-absorbing devices 10 can be arranged in a form in which one shock-absorbing device is turned upside down with respect to the other, so as to ensure firm support and durability.
[0073] The above description is only an exemplary illustration of the technical idea of this embodiment. For those with ordinary knowledge in the technical field to which this embodiment belongs, various modifications and deformations can be made without exceeding the essential features of this embodiment. Therefore, this embodiment is used to illustrate rather than limit the technical idea of this embodiment, and these embodiments are not used to limit the scope of the technical idea of this embodiment. The protection scope of this embodiment is interpreted based on the appended claims, and all technical ideas within the equivalent scope should be interpreted as belonging to the scope of the rights of this embodiment.
