[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0037] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0038] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0039] Example 1

[0040] This is the first embodiment of the present invention, which provides a reflector for a base station antenna based on beam width adjustment.

[0041] Specifically, refer to Figure 3~Figure 6 , a reflector of a base station antenna based on beam width adjustment comprises: a reflector assembly 100, comprising a reflector 101, a radiation unit 102 arranged on the end surface of the reflector 101, a side plate 103 arranged on the outer wall of the reflector 101, and a corner plate 104 arranged at the end of the side plate 103;

[0042] The adjustment assembly 200 disposed on the end surface of the reflector 101 includes a fixed shell 201 and a rotating gear 202 disposed inside the fixed shell 201. The outer wall of the rotating gear 202 is provided with a control component, and the control component is in contact with the rotating gear 202. The rotating gear 202 is driven by the control component to rotate inside the fixed shell 201 and drive the gear rack 401 meshed therewith to move to both sides inside the fixed shell 201. The outer wall of the reflector 101 is provided with a moving component, and when the gear rack 401 moves, it pushes the moving component to drive the side plate 103 and the corner plate 104 of the outer wall of the reflector 101 to flip, so as to change the width of the beam and enhance the gain of the signal.

[0043] When the control component is not connected to the rotating gear 202, the control component pushes the rotating gear 202 and causes the reflecting plate 101 to tilt. By fine-tuning the tilt angle of the reflecting plate 101, the directivity and radiation pattern of the antenna can be optimized, thereby improving the coverage of the signal.

[0044] Among them, when the control component moves, the reflecting plate 101 can be pushed to make a slight angle adjustment as a whole, and the reflecting plate 101 can be flipped with the bottom of the reflecting plate 101 as the hinge point, thereby adjusting the signal coverage direction of the radiation unit 102 on the surface of the reflecting plate 101, and at the same time, the signal interference of adjacent frequencies and the same frequency can be reduced, and the signal quality can be improved. In addition, the control component can be used to control whether the rotating gear 202 is in contact with the control component and rotates together. When the two are not in contact, the simple movement of the control component is used to adjust the angle of the reflecting plate 101. When the rotating gear 202 rotates together, the side panels 103 and the corner panels 104 on both sides of the reflecting plate 101 are driven inward through the rack 401, so as to further transmit the signal more concentratedly to the front, and at the same time, the radiation from the back of the antenna can be reduced.

[0045] Example 2

[0046] This is the second embodiment of the present invention, which is implemented based on the previous embodiment.

[0047] Specifically, refer to Figure 6 , Figure 7The control component includes a screw 203, the end of the screw 203 is in contact with the rotating gear 202, the outer wall of the screw 203 is also provided with a friction plate 207, and the outer wall array of the friction plate 207 is provided with a friction block 2071, the friction block 2071 is in contact with the outer wall of the rotating gear 202, when the screw 203 rotates, the rotating gear 202 is driven to rotate on the inner wall of the fixed shell 201 through the friction block 2071.

[0048] The screw 203 is rotatably connected to the rotating gear 202, but is not a whole. The top of the screw 203 is connected to the connecting rod of the axis of the rotating gear 202, but the rotation of the screw 203 does not affect the rotating gear 202. The friction plate 207 is sleeved on the surface of the screw 203 and is not fixed. Figure 6 As shown, the friction plate 207 slides left and right outside the screw 203 and rotates with the rotation of the screw 203. The surface array of the friction plate 207 has a plurality of friction blocks 2071. When the friction blocks 2071 are in contact with the rotating gear 202, the rotating gear 202 is driven to rotate inside the fixed shell 201 through the contact between the friction blocks 2071 and the rotating gear 202.

[0049] Preferably, a pressure plate 206 is provided on the outer wall of the friction plate 207 and a pressure spring sheet 2062 is provided on the outer wall of the pressure plate 206. The end of the pressure spring sheet 2062 facing away from the friction plate 207 is connected to a fixed shell 204. The fixed shell 204 is screwed to the outer wall of the rotating gear 202. The pressure spring sheet 2062 pushes the pressure plate 206 to make it close to the rotating gear 202. The friction plate 207 is pushed by the pressure plate 206 to press against the outer wall of the rotating gear 202.

[0050] The fixed housing 204 is screwed to the outside of the rotating gear 202 and has a certain distance from the rotating gear 202. The pressure plate 206 is located between the fixed housing 204 and the friction plate 207. A plurality of pressure springs 2062 are fixed to the outer ring of the pressure plate 206. The pressure springs 2062 push the pressure plate 206 to the left. Figure 6 As shown in the figure, the pressure plate 206 is pushed toward the friction plate 207, and the friction plate 207 is pushed toward the rotating gear 202 and fits with the rotating gear 202 through the elastic force of the pressure spring plate 2062. At this time, when the screw 203 rotates, the rotating gear 202 can be driven to rotate together through the outer friction plate 207.

[0051] The control component also includes a circular spring sheet 205, and the circular spring sheet 205 is located on the outer wall of the pressure plate 206. The outer wall of the pressure plate 206 is also provided with a fixing sheet 2061, and the end of the fixing sheet 2061 is close to the end face of the circular spring sheet 205. When the circular spring sheet 205 is squeezed at the axis, the outer wall rises and drives the pressure plate 206 to move, making it away from the friction plate 207.

[0052] Among them, the circular spring sheet 205 is in the middle of the pressure plate 206 and the fixed shell 204, and the outer ring edge of the circular spring sheet 205 is below the fixed sheet 2061 on the side of the pressure plate 206, and the circular spring sheet 205 is fixed to the outer surface of the pressure plate 206 through the fixed sheet 2061.

[0053] A ring 2051 is provided on the outer wall of the circular spring sheet 205 and a buckle 2052 is provided on the outer wall of the ring 2051. A fixing column 2053 is provided at the end of the buckle 2052 and the end of the fixing column 2053 is connected to the fixed shell 204. The position of the ring 2051 is fixed and serves as a fulcrum for the circular spring sheet 205 to tilt. A recess 2041 is provided on the outer wall of the fixed shell 204 and a connecting point 2042 is provided on the inner wall of the recess 2041. The connecting point 2042 is connected to the fixing sheet 2061 and limits the movement of the pressure plate 206.

[0054] Among them, a circular ring 2051 is arranged on each side of the circular spring sheet 205, and the circular rings 2051 on both sides are fixed to the outer side of the circular spring sheet 205 by means of a buckle 2052. At the same time, the outer side of the buckle 2052 is fixedly connected to the fixed shell 204 by a fixing column 2053. Therefore, the position of the buckle 2052 is fixed, and the position of the circular rings 2051 on both sides is also fixed, and the distance between the circular spring sheet 205 sandwiched between the two circular rings 2051 and the fixed shell 204 is also fixed.

[0055] A recess 2041 is provided on the outer side of the fixed shell 204, and the fixing plate 2061 and the pressure spring sheet 2062 on the surface of the pressure plate 206 are provided at the recess 2041, and the pressure spring sheet 2062 is connected to the connection point 2042 in the recess 2041, and the distance between the pressure plate 206 and the fixed shell 204 depends on the deformation degree of the pressure spring sheet 2062.

[0056] The control component also includes a moving sleeve 209 sleeved on the outer wall of the screw rod 203, a pushing ring 2091 is provided at the end of the moving sleeve 209, and an inclined groove 2092 is opened on the end face of the pushing ring 2091, and a rotating ring 301 is also provided on the outer wall of the pushing ring 2091, and a straight rod 3011 is provided on the end face of the rotating ring 301, and the end of the straight rod 3011 extends to the inner wall of the inclined groove 2092. When the rotating ring 301 rotates, the straight rod 3011 slides along the inner wall of the inclined groove 2092 and pushes the pushing ring 2091 to make it contact with the axis of the circular spring sheet 205, so that the outer wall of the circular spring sheet 205 is tilted and drives the pressure plate 206 to move.

[0057] Among them, the moving sleeve 209 is sleeved on the outside of the screw rod 203, moves outside the screw rod 203 and is not affected by the rotation of the screw rod 203. The pushing ring 2091 is fixed on the top of the moving sleeve 209. The two are a whole, and the surface array of the pushing ring 2091 is provided with a plurality of inclined grooves 2092. The surface of the pushing ring 2091 is attached to the inner side of the fixed shell 201. The rotating ring 301 is arranged on the outer side of the fixed shell 201. The straight rod 3011 on the surface of the rotating ring 301 passes through the arc groove on the surface of the fixed shell 201 and extends into the interior of the inclined groove 2092. By rotating the rotating ring 301, the bottom end of the straight rod 301 slides along the inner surface of the inclined groove 2092, so that the pushing ring 2091 moves in the direction of the circular spring sheet 205.

[0058] The axis center of the circular spring piece 205 is close to the bottom end of the moving sleeve 209. When the moving sleeve 209 moves toward the circular spring piece 205, the axis center of the circular spring piece 205 is pressed downward. Figure 6 As shown, the outer ring of the circular spring piece 205 is a disc, and the inner ring is composed of multiple spring pieces. When one end of the spring piece is squeezed downward, the circular ring 2051 fixed on both sides of the circular spring piece 205 is used as a fulcrum to tilt the outer disc upward.

[0059] When the outer ring of the circular spring sheet 205 tilts upward, the fixed sheet 2061 fixed on the outer ring moves together with the pressure plate 206 toward the fixed housing 204. At this time, the pressure plate 206 no longer squeezes the friction plate 207, and the squeezing force between the friction plate 207 and the rotating gear 202 is lost. When the screw 203 drives the friction plate 207 to rotate, the rotating gear 202 is stationary.

[0060] Better, refer to Figure 8 , Fig. 9 A limiting shell 208 is provided on the outer wall of the moving sleeve 209 and the limiting shell 208 is fixed to the inner wall of the fixed shell 201. A sliding groove is provided on the inner wall of the limiting shell 208. The sliding groove cooperates with the connecting rod on the outer wall of the pushing ring 2091 and limits the movement of the pushing ring 2091. A first elastic member 2093 is also provided on the outer wall of the moving sleeve 209 and the first elastic member 2093 is located on the inner wall of the limiting shell 208. When the pushing ring 2091 moves, the first elastic member 2093 is squeezed to deform it. When the pushing ring 2091 loses external force, the first elastic member 2093 restores its deformation and pushes the moving sleeve 209 to reset.

[0061] Among them, the limiting shell 208 is fixed on the inner wall of the fixed shell 201, and the screw 203 passes through the middle of the limiting shell 208. The sliding groove opened on the inner surface of the limiting shell 208 slides with the connecting rod on the outer surface of the pushing ring 2091. When the pushing ring 2091 is squeezed by the straight rod 3011 and moves downward, it moves along the sliding groove on the inner surface of the limiting shell 208, and the pushing ring 2091 is not affected by the rotation of the screw 203.

[0062] The first elastic member 2093 arranged below the push ring 2091 is located between the limiting shell 208 and the push ring 2091. When the push ring 2091 is squeezed by the straight rod 3011 to move laterally, the first elastic member 2093 is squeezed to deform. When the straight rod 3011 loses the force applied, the first elastic member 2093 recovers the deformation and returns to its original position, the push ring 2091 returns to its original position, and the rotating ring 301 located on the outer side of the fixed shell 201 also returns to its original position.

[0063] In summary, during use, under normal circumstances, since the fixed housing 204 and the rotating gear 202 are screwed together, the distance between the two is constant. The friction plate 207 is squeezed toward the friction plate 207 under the action of the outer pressure spring plate 2062 of the pressure plate 206, so that the friction block 2071 on the surface of the friction plate 207 is tightly attached to the outer surface of the rotating gear 202. When the screw 203 rotates, the friction plate 207 drives the rotating gear 202 to rotate together with the rotation of the screw 203. When the two need to be separated, the rotating ring 301 is rotated on the outer side of the fixed housing 201, and the straight rod 3011 on the surface of the rotating ring 301 moves in the inclined groove 2092 on the surface of the push ring 2091. The entire moving sleeve 209 moves laterally, and the bottom of the moving sleeve 209 is attached to the top of the middle spring sheet 205 and applies a downward force to the top. The circular ring 2051 on the outer surface of the circular spring sheet 205 is fixed to the inside of the fixed shell 204 by the buckle 2052, acting as a fulcrum for the flipping of the circular spring sheet 205. Therefore, when the spring sheet of the inner circle is squeezed and moved downward, the outer circle of the circular spring sheet 205 will tilt up and drive the pressure plate 206 to move toward the fixed shell 204 through the fixed plate 2061. At this time, the friction plate 207 loses the push of the pressure plate 206, and a gap appears between it and the rotating gear 202. Therefore, the rotation of the friction plate 207 no longer drives the rotating gear 202 to rotate.

[0064] Example 3

[0065] This is the third embodiment of the present invention, which is implemented based on the previous embodiment.

[0066] Specifically, refer to Fig.10The moving parts include a push rod 402 connected to the rack 401, a special-shaped rod 4021 is hinged at the end of the push rod 402, a special-shaped block 4022 is movably connected at the end of the special-shaped rod 4021, the special-shaped block 4022 is hinged to the outer wall of the side plate 103 and a groove 4023 is provided at one end of the special-shaped block 4022, a first connecting plate 4024 is hinged at the other end of the special-shaped block 4022 and a first pushing column 4025 is hinged at the end of the first connecting plate 4024. When the push rod 402 moves, the end of the special-shaped rod 4021 at the front end is engaged in the groove 4023 at the end of the special-shaped block 4022 and drives the special-shaped block 4022 to flip, and pushes the first pushing column 4025 to move through the first connecting plate 4024.

[0067] Among them, the push rod 402 and the rack 401 are connected as a whole. The rack 401 is fixed inside the fixed shell 201, extends from the opening 2011 on the side of the fixed shell 201, and meshes with the rotating gear 202. When the rotating gear 202 is driven by the friction plate 207 to rotate, the racks 401 on the upper and lower sides extend outward and drive the push rods 402 on both sides to push to both sides.

[0068] like Fig.11 As shown, a special-shaped rod 4021 is hinged at the top position of the push rod 402, one end of the special-shaped rod 4021 is hinged to the surface of the side plate 103, and the other end is a longer end extending out of the push rod 402. When the push rod 402 is extended outward, the end of the special-shaped rod 4021 hinged to the side plate 103 is subjected to tension, and the front end of the special-shaped rod 4021 is turned over with the hinge point of the special-shaped rod 4021 and the push rod 402 as the fulcrum, and the front end of the special-shaped rod 4021 is snapped into the groove 4023 at the end of the special-shaped block 4022, and as the push rod 402 is pushed, the front end of the special-shaped rod 4021 is moved in the special-shaped block 4022. The first connecting plate 4024 is pushed forward by the push rod 4021 to move the first connecting plate 4024. At the same time, a movable groove is provided at one end of the special-shaped rod 4021 hinged to the side plate 103. When the front end of the special-shaped rod 4021 presses down one end of the groove 4023 of the special-shaped block 4022, the hinged rod of the side plate 103 slides in the movable groove and is pushed by the push rod 402 to drive the side plate 103 to flip inward on both sides of the reflector 101.

When the first push column 4025 moves, the angle plate 4027 is driven to rotate through the second connecting plate 4026;

[0070] The end of the angle plate 4027 is hinged with an inclined rod 4028 and the end of the inclined rod 4028 is hinged with a second push column 4029, the end of the second push column 4029 is hinged with a universal shaft 403 and the other end of the universal shaft 403 is connected to a protrusion 1041 arranged on the outer wall of the angle plate 104. When the angle plate 4027 is flipped, the second push column 4029 is pushed to move by the inclined rod 4028 and finally the angle plate 104 is flipped on the outside of the side plate 103.

[0071] Among them, the front end of the first pushing column 4025 is hinged with the second connecting plate 4026, one end of the angular plate 4027 is hinged with the second connecting plate 4026, and the other end is hinged with the inclined rod 4028. When the second connecting plate 4026 is pushed forward by the first pushing column 4025, it drives one end of the angular plate 4027 to flip upward, and the inclined rod 4028 at the other end of the angular plate 4027 pushes the second pushing column 4029 to move to both sides as the angular plate 4027 flips. The second pushing column 4029 is fixed on the surface of the side plate 103, and a universal shaft 403 is rotatably set at the end. The other end of the universal shaft 403 is fixedly connected to the protrusion 1041 on the surface of the angle plate 104. Therefore, with the push of the second pushing column 4029, the angle plate 104 is flipped at the top end of the side plate 103.

[0072] Example 4

[0073] This embodiment provides a base station antenna, referring to Figure 1~Figure 5 A reflector for a base station antenna based on beam width adjustment is applied to a base station antenna, which includes a main body component 500, including a base station antenna 501, an inner wall of the base station antenna 501 is provided with a receiving cavity 502 for installing a reflector assembly 100 and an adjustment assembly 200, the reflector 101 is installed on the inner wall of the receiving cavity 502 and a fixing shell 201 is fixed to the outer wall of the base station antenna 501.

[0074] In summary, when in use, the fixed shell 201 is installed on the outer wall of the base station antenna 501, and one side is fixed to the reflector 101. The rotation of the screw 203 drives the friction plate 207 to rotate. At the same time, due to the threads on the surface of the screw 203, the length of the screw 203 on the outer wall of the base station antenna 501 changes, so that the fixed shell 201 moves inside the base station antenna 501, and pushes the reflector 101 to flip inside the accommodating cavity 502 of the base station antenna 501 with the hinge point below as the fulcrum. The reflector 101 adjusts the tilt angle inside the base station antenna 501, and at this time, the friction plate 207 is tightly attached to the rotating gear 202, the rotating gear 202 rotates, and drives the rack 401 inside the fixed shell 201 to move, and finally the side plates 103 on both sides of the reflector 101 are turned over. And the angle plate 104 on the top of the side plate 103 is flipped and moved inward on the surface of the reflecting plate 101, so that the signal of the radiation unit 102 at the front end of the reflecting plate 101 is reflected more concentratedly to the front. At the same time, when there is no need to adjust the side plates 103 and the angle plates 104 on both sides of the reflecting plate 101, by rotating the swivel 301, the friction plate 207 is not in contact with the rotating gear 202 through the movement of the moving sleeve 209, and only the inclination angle of the reflecting plate 101 inside the base station antenna 501 can be adjusted. By fine-tuning the inclination angle of the reflecting plate 101, the directivity and radiation pattern of the antenna can be optimized, thereby improving the coverage range of the signal. At the same time, it helps to direct the signal more concentratedly to the target area, thereby enhancing the signal strength in the area, and can also reduce adjacent frequency and same frequency interference, thereby improving communication quality.
