Description
Technical Field
The present disclosure relates to a device for sensing tilt and direction and an antenna assembly using the same.
Background
The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.
The mobile communication base station determines an appropriate antenna installation position according to the network design result. Based on the vertical up/down tilt of the antenna beam and the sector direction angle of the horizontal direction, an appropriate antenna tilt angle and azimuth angle can be designed. In order to adapt the installed antenna to the propagation environment in the field, the tilt angle and azimuth angle can be optimized by testing.
The wireless signal in the 3.5GHz frequency band of 5G has stronger propagation linearity, so that the preset service coverage can be obtained only by installing an antenna in a preset antenna azimuth angle, and the same index can be adopted for design and optimization in the later capacity expansion. The minimization of the higher the band azimuth error appears more important.
The tilt angle and azimuth angle of the antenna must be readjusted according to a change in the wireless environment, etc., and the tilt of the mast (post) to which the antenna is mounted may be changed or a clamp for coupling the antenna and the mast may be twisted in a horizontal direction due to an influence of an external environment such as strong wind.

Fig. 1 is a perspective view of an antenna assembly according to an embodiment of the present disclosure.
Referring to fig. 1, an antenna assembly (antenna assembly) 1 of the present disclosure may include all or a portion of an antenna device (antenna apparatus) 12 and a device (tilt and direction detecting apparatus) 11 for sensing tilt and direction.
The means 11 for sensing tilt and direction is fixed to the antenna means 12 and is capable of measuring three-dimensional spatial direction information of the antenna means 12 in real time.

Fig. 2 is a perspective view of an apparatus for sensing tilt and direction according to an embodiment of the present disclosure.
Fig. 3 is an exploded perspective view of an apparatus for sensing tilt and direction according to an embodiment of the present disclosure.
Fig. 4 is a cross-sectional view of an apparatus for sensing tilt and direction according to an embodiment of the present disclosure.
Referring to fig. 2 to 4, the apparatus 11 for sensing tilt and direction may include all or a part of a cover structure (FPCB) 111, a flexible circuit board (flexible printed circuit board) 112, a cover member (cover member) 113, and a main board 114.
The cap structure 111 may include a spherical surface 1111 and a through hole 1112. The spherical surface 1111 may include a plurality of support surfaces 1111a, and a base portion 1121 of the flexible circuit substrate 112 is disposed on each support surface 1111 a.
The spherical surface 1111 of the cover-like structure 111 may be constituted by a plurality of polyhedrons such as a circle, a triangle, a pentagon, a hexagon, or a combination thereof. However, the present disclosure is not limited thereto, and the spherical surface 1111 of the cover-like structure 111 may be entirely curved.
The flexible circuit board 112 may encase at least a portion of the spherical surface 1111 of the cap structure 111. The flexible circuit substrate 112 includes a base portion 1121, and a photo sensor 1121a capable of receiving sunlight is arranged on the base portion 1121. Next, the structure of the flexible circuit board 112 will be described in detail.
The device 11 for sensing tilt and direction of the present disclosure arranges the plurality of photo sensors 1121a on the hood-like structure 111 using the flexible circuit substrate 112, so that the production efficiency of the device 11 for sensing tilt and direction can be improved. The flexible circuit board 112 is provided to encase the hood-like structure 111, so that the plurality of photo sensors 1121a can be easily mounted on the plurality of support surfaces 1111 a.
The device 11 for sensing inclination and direction is more easily assembled than the prior art, i.e., the technology of mounting the unit substrates having the photo sensor modules on the respective support surfaces, respectively, and as a result, the production efficiency of the device 11 for sensing inclination and direction can be improved.
In a state where the flexible circuit substrate 112 is arranged on the spherical surface 1111, the plurality of photo sensors 1121a may be arranged to face mutually different directions, respectively. Each of the light sensors 1121a may receive sunlight from a direction in which each of the light sensors 1121a is directed. For example, the light sensor 1121a may receive sunlight from a normal direction of each support surface 1111 a.
The cover member 113 may be disposed on the base portion 1121, the base portion 1121 being disposed on the support surface 1111 a. The cover member 113 may include a light receiving hole 1131 corresponding to the light sensor 1121a. The light receiving hole 1131 may allow the photo sensor 1121a to receive only sunlight incident from a specific direction. For example, the light receiving hole 1131 may allow the photo sensor 1121a to receive only sunlight incident from the normal direction of the support surface 1111a and the direction adjacent thereto. The light receiving hole 1131 can block sunlight incident from directions other than the normal direction of the support surface 1111a and the direction adjacent thereto.
The receiving range of the light receiving hole 1131 receiving the sunlight may be set to be different according to the number of the photo sensors 1121a of the device 11 for sensing inclination and direction. For example, if the number of the photo sensors 1121a is large, the light receiving hole 1131 may be designed to receive a relatively narrow range of sunlight or to receive sunlight in a specific direction, for example, a normal direction of the support surface 1111a, in order to improve the sensing accuracy of each photo sensor 1121a. Conversely, if the number of the photo sensors 1121a is small, the light receiving holes 1131 may be designed to receive a wider range of sunlight in order to expand the sensing range of each photo sensor 1121a. The receiving range of the light receiving hole 1131 to receive sunlight may be adjusted by changing the diameter or shape of the light receiving hole 1131.
The main board 114 may calculate an incident angle of sunlight from output information of the plurality of photo sensors 1121a. Motherboard 114 may include a first face 1141 adjacent to hood-like structure 111, a second face 1142 opposite first face 1141, and a through slot 1143.
At least a portion of the second connection portion 1124 of the flexible circuit substrate 112 may pass through the through groove 1143, and one end of the second connection portion 1124 may be connected to the second surface 1142 of the motherboard 114.
In the conventional device for sensing tilt and direction, the electric wires extending from each unit substrate can be electrically connected to the first surface of the main board by mounting the unit substrate having the photo sensor module on each supporting surface. In this case, since the electric wires are arranged scattered between the inner wall of the hood-like structure and the main board, the assemblability of the device for sensing tilt and direction may be reduced.
In contrast thereto, the device 11 for sensing tilt and direction of the present disclosure is provided to connect the second connection portion 1124 of the flexible circuit substrate 112 to the second face 1142 of the main board 114, so that the assemblability of the device 11 for sensing tilt and direction can be improved.
The device 11 for sensing tilt and orientation of the present disclosure may further include a housing 115, a protective cap 116, a voltage pad 117, and a control cable 118.
The housing 115 may form the outer shape of the device 11 for sensing inclination and direction, and may internally mount a plurality of components. The protective cap 116 may be arranged to completely encase the spherical surface 1111 of the cap-like structure 111. The protective cap 116 may protect the internal components from external force impact and may prevent foreign objects from flowing into the inside of the device 11 for sensing inclination and direction. The overvoltage disc 117 may be disposed at a lower portion of the main board 114. Also, the overvoltage disc 117 may supply power to various components of the device 11 for sensing inclination and direction. The means 11 for sensing tilt and direction can send and receive measurement data and control data via the control cable 118.
Fig. 5 is a bottom view of a cover member of an apparatus for sensing tilt and direction according to an embodiment of the present disclosure.
Referring to fig. 5, the cover member 113 may include all or a portion of the light receiving hole 1131, the plurality of support portions 1132, the protruding portion 1133, and the cover body 1135.
The light receiving hole 1131 may allow the light sensor 1121a to receive only sunlight incident from the normal direction of the support surface 1111a and the direction adjacent thereto. Further, the light receiving hole 1131 may block sunlight incident from outside the normal direction of the support surface 1111a and the direction adjacent thereto. At this time, the sensing range of the photo sensor 1121a may be widened.
However, the present disclosure is not limited thereto, and a receiving range of the light receiving hole 1131 to receive sunlight may be limited to a specific direction in order to improve sensing accuracy of the light sensor 1121a. For example, the light receiving range of the light receiving hole 1131 may be defined in the normal direction of the support surface 1111a or a narrower range adjacent thereto.
The plurality of support portions 1132 may be provided to extend from one surface of the cover member 113, and support the cover 1135 on the support surface 1111a of the cover-like structure 111. The support portion 1132 may be welded to the support surface 1111a by laser, but the present disclosure is not limited thereto. For example, the support portion 1132 may be fixed to the support surface 1111a by an adhesive or the like.
Each support portion 1132 of the plurality of support portions 1132 may be arranged around the light receiving hole 1131 at intervals. A space is formed between two adjacent support portions 1132 through which the first connection portion 1123 of the flexible circuit substrate 112 may pass.
The support portion 1132 may include a first support portion 1132a, a second support portion 1132b adjacent to the first support portion 1132a, and a third support portion 1132c adjacent to the second support portion 1132 b. The cover member 113 is supported at three points by the three support portions 1132, so as to be firmly fixed to the support surface 1111 a.
The first space 1134a may be larger than the second space 1134b, the first space 1134a is a space between the first support portion 1132a and the second support portion 1132b, and the second space 1134b is a space between the second support portion 1132b and the third support portion 1132c. The device 11 for sensing inclination and direction of the present disclosure may improve the degree of freedom of the extending direction of the first connection portion 1123 using the first space 1134 a.
The third support portion 1132c is disposed symmetrically to the second support portion 1132b with respect to the first support portion 1132 a. The third space 1134c is a space between the first support portion 1132a and the third support portion 1132c, and may have the same size as the second space 1134 b. However, the present disclosure is not limited thereto, and the third support portion 1132c may be disposed not to be symmetrical with the second support portion 1132b with respect to the first support portion 1132 a.
Referring to fig. 5, although the number of the stay 1132 is illustrated as three, the present disclosure is not limited thereto. For example, the covering member 113 may further include at least two or at least four support portions 1132.
The protruding portion 1133 may be provided so as to be capable of being inserted into the through hole 1112 of the cover-like structure 111. The projection 1133 is inserted into the through hole 1112, so that the cover member 113 can be fixed to the cover-like structure 111.
The through hole 1112 may include a first through hole 1112a and a second through hole 1112b, and the protrusion 1133 may include a first protrusion 1133a and a second protrusion 1133b, the first protrusion 1133a having a shape corresponding to the first through hole 1112a, and the second protrusion 1133b having a shape corresponding to the second through hole 1112b.
The first through hole 1112a may have a different size or shape than the second through hole 1112b, and thus, the first protrusion 1133a may have a different size or shape than the second protrusion 1133 b. For example, the first through hole 1112a and the first protrusion 1133a have larger dimensions than the second through hole 1112b and the second protrusion 1133b, respectively.
The first through hole 1112a and the first protrusion 1133a have different sizes or shapes from the second through hole 1112b and the second protrusion 1133b, respectively, so that the mounting direction of the cover member 113 on each support surface 1111a can be fixed in a specific direction.
When the mounting direction of the cover member 113 on each support surface 1111a is fixed in a specific direction, the direction in which the space between each support portion 1132 is formed is also fixed in a specific direction.
The mounting direction of each cover member 113 may be set to be different according to the shape of the flexible circuit substrate 112. Specifically, it may be set to be different according to the extending direction of the first connection portion 1123 of the flexible circuit substrate 112. Thereby, the degree of freedom in design of the flexible circuit substrate 112 according to an embodiment of the present disclosure can be further improved.
Fig. 6 is a top view of a flexible circuit substrate for an apparatus for sensing tilt and direction according to an embodiment of the present disclosure.
Referring to fig. 6, the flexible circuit substrate 112 of the device 11 for sensing tilt and direction of the present disclosure may include a plurality of base units (base units) 1121, a plurality of first connection portions 1123, and a plurality of second connection portions 1124.
The base portion 1121 may include a photo sensor 1121a, a circuit portion 1121b in which the photo sensor 1121a is arranged, and a reinforcing plate 1122 arranged at a lower portion of the circuit portion 1121 b. The reinforcing plate 1122 can strengthen the rigidity of the circuit portion 1121b by thickening the region of the flexible circuit board 112 where the circuit portion 1121b is formed. The reinforcing plate 1122 can minimize the problem of deformation or damage of the circuit portion 1121b due to external force or the like, and can also minimize the problem of damage of the photo sensor 1121a or the like disposed on the circuit portion.
Each base portion 1121 of the plurality of base portions 1121 may be disposed on each support surface 1111a of the plurality of support surfaces 1111 a. Each of the plurality of photo sensors 1121a may be disposed on each of the plurality of base portions 1121. For example, a plurality of photo sensors 1121a may be arranged on the circuit portion 1121b of the base portion 1121.
The base portion 1121 may have a thicker thickness than the first connection portion 1123 by reinforcing the rigidity of the circuit portion 1121b with the reinforcing plate 1122. Accordingly, the problem of damage to the photo sensor 1121a or the like disposed on the base portion 1121 due to unexpected bending of the base portion 1121 by external force or the like can be minimized.
The reinforcement plate 1122 may not be disposed on the first connecting portion 1123. Accordingly, the second thickness W2 of the first connection portion 1123 may be smaller than the first thickness W1 of the base portion 1121. Since the first connection portion 1123 is thin and flexibly deformable, the flexible circuit substrate 112 can be easily disposed on the cover-like structure 111.
The circuit portion 1121b may include polyimide (polyimide) as a conventional material of the flexible circuit substrate 112. However, the present disclosure is not limited thereto, and the circuit portion 1121b may include other materials in addition thereto.
The reinforcement plate 1122 may include at least one of PET, glass epoxy, and polyimide. The present disclosure is not limited thereto and reinforcement plate 1122 may include other materials in addition thereto.
Although sixteen base portions 1121 are shown in fig. 6, this is merely illustrative for convenience of explanation, and the number of base portions 1121 of the present disclosure is not limited to sixteen. Accordingly, the flexible circuit substrate 112 according to the present disclosure may further include sixteen or more base portions 1121. In this case, the number of the photo-sensors 1121a arranged at the base portion 1121 or the number of the support surfaces 1111a of the cover-like structure 111 may also be set to be different depending on the number of the base portions 1121.
The first connection portion 1123 may connect two adjacent base portions 1121 among the plurality of base portions 1121. The first connection portion 1123 is different from the base portion 1121, does not have the reinforcing plate 1122, and thus may be relatively thin in thickness as compared to the base portion 1121. Accordingly, the first connection portion 1123 may be flexibly deformed, and the final flexible circuit substrate 112 may more easily encase the spherical surface of the cover-like structure 111.
The second connection portion 1124 may electrically connect the plurality of photo sensors 1121a and the motherboard 114. The second connection portion 1124 may include signal lines, power supply lines, and the like. Also, one end of the second connection part 1124 may have a terminal or connector for electrically connecting the main board 114.
The flexible circuit substrate 112 having the base portion 1121, the reinforcement plate 1122, the first connection portion 1123, and the second connection portion 1124 may be integrally formed. Therefore, wiring of the electric wires for supplying power to the plurality of photo sensors 1121a and for supplying power will become simpler.
The base portion 1121 may include mounting holes. The protrusion 1133 of the cover member 113 may penetrate the mounting hole. When the protrusion 1133 includes the first protrusion 1133a and the second protrusion 1133b having different sizes or shapes from each other, the mounting hole may include a first mounting hole 1121c corresponding to the first protrusion 1133a and a second mounting hole 1121d corresponding to the second protrusion 1133 b. When the cover member 113 is combined with the supporting surface 1111a, the first protrusion 1133a may penetrate the first mounting hole 1121c, and the second protrusion 1133b may penetrate the second mounting hole 1121d.
For example, when the cover member 113 is coupled with the support surface 1111a, the first protrusion 1133a may penetrate the first mounting hole 1121c of the base portion 1121 and the first through hole 1112a of the support surface 1111a, and the second protrusion 1133b may penetrate the second mounting hole 1121d of the base portion 1121 and the second through hole 1112b of the support surface 1111 a.
In addition, although the number of flexible circuit boards 112 disposed on the spherical surface 1111 of the cover-like structure 111 is illustrated as one in fig. 6, the present disclosure is not limited thereto. For example, a plurality of flexible circuit boards 112 may be disposed on the spherical surface 1111 of the cover-like structure 111. In this case, the plurality of photo sensors 1121a may be dispersedly arranged on the plurality of flexible circuit substrates 112.
In addition, the shape of the flexible circuit substrate 112 shown in fig. 6 is exemplarily illustrated for convenience of description, and the flexible circuit substrate 112 of the present disclosure may have a shape other than the embodiment shown in fig. 6.
The above is merely for illustrating the technical idea of the present embodiment, and it is obvious to those skilled in the art to which the present embodiment pertains that various modifications and variations can be made without exceeding the essential features of the present embodiment. Therefore, the present embodiment is not intended to limit the technical idea of the present embodiment but is intended to be illustrative, and the scope of the technical idea of the present embodiment is not limited by the embodiment. The scope of the present embodiment should be construed based on the following claims, and all technical ideas within the scope equivalent thereto should be construed to be all falling within the scope of the present embodiment.
