Description

Technical Field

[0001] This invention relates to the field of electrically adjustable antenna technology, and in particular to an antenna electrical downtilt angle display component and antenna. Background Technology

[0002] Antenna downtilt is the angle at which a mobile communication base station antenna tilts relative to the horizontal line. Adjusting this angle directly changes the antenna's beam coverage. Antenna downtilt can be divided into mechanical downtilt and electrical downtilt based on the method of implementation.

[0003] Base station antennas typically require electrical downtilt adjustment during operation. To allow operators to visually observe the downtilt angle on the antenna, designers usually incorporate a readable downtilt display device. Patent CN202210296874.0 discloses an electrical downtilt adjustment device; however, this patent does not specify the display method for the downtilt angle. Therefore, it is necessary to provide a highly versatile and simple antenna downtilt display component for easy operator reading. Summary of the Invention

[0004] The purpose of this invention is to provide a highly versatile and simple antenna electrical downtilt angle display component for easy reading by operators. To achieve this purpose, the following technical solution is adopted:

[0005] The first aspect of this invention provides an antenna electrical downtilt angle display assembly, including a support base, a transmission component, an end cap, and a scale. The transmission component is installed in the support base via a guide groove. The scale is elongated and has graduation markings on its surface. The tail of the scale extends beyond the end cap, and the head of the scale is slidably mounted on the transmission component and located between the tail end of the transmission component and the support base. The scale does not move with the movement of the transmission component. When the transmission component moves back and forth in the guide groove, the slidable length of the scale head on the transmission component can be changed. Thus, when the scale is manually stretched so that the scale head reaches the limiting end face of the tail end of the transmission component, the real-time antenna electrical downtilt angle is displayed through the graduation markings extending beyond the end cap.

[0006] A further improvement is that a spring is fitted onto the scale, one end of the spring is connected to one end of the scale head, and the other end of the spring abuts against the back of the end cap. A limit block is provided on the support base. Under the action of the spring force, the scale head collides with the limit block, so that the scale does not move with the movement of the transmission component. The limit end face and the limit block together limit the sliding length of the scale head on the transmission component.

[0007] A further improvement is that the scale head is symmetrically provided with a front collision point and a rear collision point on the left and right sides respectively. The front collision point is used to collide with the limiting end face for limiting, and the rear collision point is used to collide with the limiting block for limiting.

[0008] A further improvement is that one end of the scale is provided with a slanted boss, and a groove is formed between the slanted boss and the head of the scale, and one end of the spring slides into the groove through the slanted boss.

[0009] A further improvement is that the top surface of the transmission component is provided with a groove for the scale to slide, and the scale head is symmetrically provided with buckles on the left and right sides. The transmission component is provided with long protrusions on the left and right sides, and the top of the long protrusions is provided with a guide surface. The two buckles of the scale are pressed against the guide surface and then locked onto the long protrusions.

[0010] A further improvement is that several sets of sliding ribs are provided on the outer surface of the scale head, which are used to reduce the sliding resistance between the scale and the transmission component.

[0011] A further improvement is that a chamfer is provided on the limiting end face of the transmission component, which is used to prevent the spring from rubbing against the limiting end face when it extends or retracts.

[0012] A further improvement is that a threaded column is installed in the support base through a stud groove, and when the threaded column rotates, it can drive the transmission component to move back and forth in the guide groove of the support base.

[0013] A further improvement is that the transmission component is located above the threaded post, and the bottom surface of the transmission component is provided with a thread that matches the threaded post.

[0014] A second aspect of the present invention provides an antenna, including a base plate, a transmission mechanism, and a phase shifter, and further including an antenna electrical downtilt angle display component as described in any of the foregoing. The transmission mechanism is used to drive a transmission component to move back and forth, and the head end of the transmission component is connected to a corresponding phase shifter so as to adjust the tilt angle of the phase shifter when the transmission component moves back and forth.

[0015] The beneficial effects of this invention are:

[0016] The present invention provides an antenna electrical downtilt angle display component. By manually stretching the scale compression spring, the head of the scale reaches the limiting end face of the tail end of the transmission component. The front collision point collides with the limiting end face to limit the scale so that it can no longer be stretched. At this time, the scale mark value displayed on the protruding end cover of the tail end of the scale is read to achieve the purpose of reading the corresponding scale data after the movement of the transmission component. It has the advantages of high versatility, simple structure and convenient reading by operators.

[0017] Since the scale does not move with the transmission components, only a small section of the scale protrudes from the end cap when the scale is not manually stretched. When it is necessary to read the scale value, the scale is manually stretched and the value is read. After the scale is released, the scale automatically retracts under the action of the spring. The rear collision point of the scale collides with the limiting block of the support base to limit the scale and restore it to its original position. This makes most of the scale hidden inside the end cap, resulting in high space utilization and a neat appearance. Attached Figure Description

[0028] It should be noted that when a component is referred to as "fixed to," "set on," "fixed to," or "mounted to" another component, it can be directly on the other component or there may be an intermediate component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component. Furthermore, when a component is considered to be "transmittally connected" to another component, the two components only need to be able to transmit power; the specific implementation can be achieved using existing technologies, which will not be elaborated here. When a component is perpendicular or approximately perpendicular to another component, it means that the two components are ideally perpendicular, but due to manufacturing and assembly effects, there may be a certain degree of perpendicularity error. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only and do not represent the only possible implementation.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] In this invention, the terms "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0031] Please refer to the attached document. Figure 1 - Appendix Figure 7 This invention provides an antenna electrical downtilt angle display component, including a support base 3, a transmission component 5, an end cap 2, and a scale 6. The support base 3 is fixed, and the transmission component 5 is installed in the support base 3 through a guide groove 31. The scale 6 is elongated and has scale markings 61 on its surface, which are distributed along the length of the scale 6. The tail of the scale 6 extends out of the end cap 2, and the head of the scale 6 is slidably mounted on the transmission component 5 and located between the tail of the transmission component 5 and the support base 3. The scale 6 does not move with the movement of the transmission component 5. When the transmission component 5 moves back and forth in the guide groove 31, the slidable length of the head of the scale 6 on the transmission component 5 can be changed. Thus, when the scale 6 is manually stretched so that the head of the scale 6 reaches the limiting end face 53 of the tail of the transmission component 5, the real-time antenna electrical downtilt angle is displayed through the value of the scale markings 61 extending out of the end cap 2.

[0032] In this embodiment, a spring 7 is sleeved on the scale 6. One end of the spring 7 is connected to one end of the head of the scale 6, and the other end of the spring 7 abuts against the back of the end cap 2. A limit block 33 is provided on the support base 3. Under the elastic force of the spring 7, the head of the scale 6 collides with the limit block 33, so that the scale 6 does not move with the movement of the transmission member 5. The limit end face 53 and the limit block 33 together limit the sliding length of the head of the scale 6 on the transmission member 5.

[0033] In this embodiment, as Figure 4 As shown, the scale 6 has a front collision point 64 and a rear collision point 65 symmetrically arranged on the left and right sides of the head. The front collision point 64 is used to collide with the limiting end face 53 for limiting, and the rear collision point 65 is used to collide with the limiting block 33 for limiting.

[0034] The working principle of this invention is as follows: Figure 1 As shown, the tail of the scale 6 extends out of the end cover 2 through the through hole. The tail of the spring 7 is placed on the back of the end cover 2 and abuts against the back of the end cover 2. Under the action of the end cover 2 and the scale 6, the spring 7 has a certain amount of compression. The elastic force generated by this compression should not be less than the resistance generated when the scale 6 and the transmission component 5 slide against each other, so that the scale 6 does not move with the movement of the transmission component 5. At this time, only a small section of the tail of the scale 6 protrudes out of the end cover 2, and the scale mark 61 displayed by the protruding end cover 2 should be the designed starting degree (such as 0 degrees).

[0035] When the transmission component 5 moves back and forth in the guide groove 31 of the support base 3, the scale 6 does not move with the transmission component 5 under the elastic force of the spring 7. After the transmission component 5 moves, the sliding length of the head of the scale 6 on the transmission component 5 will change. At this time, the scale 6 can be manually stretched to compress the spring 7 so that the head of the scale 6 reaches the limiting end face 53 at the tail end of the transmission component 5. The front collision point 64 collides with the limiting end face 53 to limit the scale 6 so that it can no longer be stretched. Then, the scale mark 61 value displayed on the protruding end cap 2 at the tail end of the scale 6 can be read to achieve the purpose of reading the corresponding scale data after the transmission component 5 moves. After reading the value of scale mark 61, you can release your hand. When the scale 6 automatically retracts under the action of spring 7, the rear collision point 65 of the scale 6 collides with the limiting block 33 of the support base 3 to limit the scale 6 to return to its original position. At this time, the value of scale mark 61 displayed outside the end cap 2 at the tail of the scale 6 is the design starting degree (such as 0 degrees).

[0036] In this embodiment, as Figure 2 and Figure 3As shown, one end of the scale 6 is provided with a slanted protrusion 62, and a groove 63 is formed between the slanted protrusion 62 and the head of the scale 6. One end of the spring 7 can easily slide into the groove 63 through the slanted protrusion 62, thereby assembling the spring 7 and the scale 6 into one piece, while the slanted protrusion 62 can prevent the spring 7 from falling off the scale 6.

[0037] In this embodiment, as Figure 2 , Figure 5 , Figure 7 As shown, the top surface of the transmission component 5 is provided with a groove 57 for the scale 6 to slide. The scale 6 has symmetrical buckles 66 on the left and right sides of its head. The transmission component 5 has long protrusions 56 on the left and right sides respectively. The top of the long protrusions 56 is provided with a guide surface 55. The two buckles 66 of the scale 6 are pressed against the guide surface 55 and then locked onto the long protrusions 56. Since the buckles 66 are locked onto the long protrusions 56, the scale 6 can slide freely along the direction of the groove 57 without disengaging, making the extension and retraction of the scale 6 more stable and smooth.

[0038] In one embodiment of the present invention, such as Figure 5 As shown, a number of sliding ribs 67 are provided on the outer surface of the head of the scale 6. By providing the sliding ribs 67, the contact area between the scale 6 and the transmission component 5 is reduced. Therefore, the sliding ribs 67 can be used to reduce the sliding resistance between the scale 6 and the transmission component 5.

[0039] In one embodiment of the present invention, such as Figure 2 As shown, the limiting end face 53 of the transmission component 5 is provided with a chamfer 54. The chamfer 54 is used to prevent the spring 7 from scraping against the limiting end face 53 during extension and retraction, thereby affecting the sliding of the scale 6.

[0040] In this embodiment, as Figure 2 As shown, a threaded post 4 is installed in the support base 3 through the stud groove 32. When the threaded post 4 rotates, it can drive the transmission component 5 to move back and forth in the guide groove 31 of the support base 3. The threaded post 4 is driven by an external transmission mechanism (not shown).

[0041] Specifically, the transmission component 5 is located above the threaded post 4, and the bottom surface of the transmission component 5 is provided with a thread that matches the threaded post 4.

[0042] The beneficial effects of this embodiment are as follows: The antenna electrical downtilt angle display component provided in this embodiment allows the scale 6 to be manually stretched to compress the spring 7 so that the head of the scale 6 reaches the limiting end face 53 at the tail end of the transmission component 5. The front collision point 64 then collides with the limiting end face 53 to limit the scale 6 so that it can no longer be stretched. At this time, the scale mark 61 displayed on the protruding end cover 2 at the tail end of the scale 6 is read to achieve the purpose of reading the corresponding scale data after the transmission component 5 has moved. It has the advantages of high versatility, simple structure, and convenient reading for operators.

[0043] Since the scale 6 does not move with the transmission component 5, only a small section of the tail of the scale 6 protrudes from the end cover 2 when the scale 6 is not manually stretched. When it is necessary to read the value of the scale mark 61, the scale 6 is manually stretched and the value of the scale mark 61 is read. After the hand is released, the scale 6 automatically retracts under the action of the spring 7. When the rear collision point 65 of the scale 6 collides with the limiting block 33 of the support base 3, the scale 6 returns to its original position, so that most of the scale 6 is hidden inside the end cover 2. The space utilization is high and the appearance is neat.

[0044] This invention also proposes an antenna, including a base plate 1, a transmission mechanism (not shown), and a phase shifter (not shown), and further including an antenna electrical downtilt angle display component as described in any of the foregoing embodiments. The transmission mechanism is used to drive the threaded column 4 to rotate circumferentially, thereby driving the transmission component 5 to move back and forth. The head end of the transmission component 5 is connected to the corresponding phase shifter so as to adjust the tilt angle of the phase shifter when the transmission component 5 moves back and forth.

[0045] It should be noted that since the transmission mechanism and other parts of the antenna are all existing technologies, this invention does not improve these parts of the structure. Therefore, this embodiment will not describe their structure in detail. Those skilled in the art can refer to the existing technology.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The embodiments described above are merely illustrative of specific implementations of the present invention, and while the descriptions are detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements are all protected by the present invention.
