[0044] Please refer to Figures 1 to 7The embodiment of the present application provides an antenna bracket, including a base assembly 100, a column 200, a support assembly and an attachment member 400; the base assembly 100 is suitable for being installed on an installation object 01, and the installation object 01 has a certain angle with the horizontal plane; the support assembly includes at least one telescopic rod 310, and the two ends of the telescopic rod 310 are respectively hinged to the column 200 and the base assembly 100; the attachment member 400 is fixedly connected to the base assembly 100, and the attachment member 400 includes a column support member 410, and the column support member 410 includes three support surface parts and three curved surface parts, the three support surface parts are respectively recorded as a first support surface part 414, a second support surface part 415 and a third support surface part 417, and the three curved surface parts are respectively recorded as a first curved surface part 412 and a third curved surface part 413, and the two side extension surfaces of the three support surface parts are arranged to form a prism-shaped pyramid, and the two sides of the curved surface part are respectively connected to and tangent to two adjacent support surface parts; the bottom of the column 200 is a cylindrical structure, and the inner circumference of the bottom of the column 200 is in contact with the three curved surface parts.

[0045] It should be understood that if Figure 1 and Figure 2 As shown, the installation object 01 can be the sloping roof of a house. By installing the base assembly 100 on the sloping roof, the antenna bracket can be installed on the house with a sloping roof. In addition, the signal strength of the antenna is best when the antenna bracket is substantially perpendicular to the horizontal plane. However, since the roof is not parallel to the horizontal plane, it is difficult to ensure that the antenna bracket is substantially perpendicular to the horizontal plane. The antenna bracket provided in this embodiment, since the angle between the column 200 and the base assembly 100 can be adjusted by the support assembly, after the base assembly 100 of the antenna bracket is installed on the sloping roof, the angle between the column 200 and the bracket of the base assembly 100 can be adjusted so that the column 200 is substantially perpendicular to the ground plane, so that the antenna at the top of the column 200 can be substantially perpendicular to the horizontal plane, thereby ensuring that the antenna has a better signal strength. It can be seen that the antenna bracket provided in the embodiment of the present application can be well applied to houses with sloping roofs.

[0046] In this embodiment, the antenna bracket provided by the embodiment of the present application includes a base assembly 100, a column 200 and a support assembly, and the support assembly includes at least one telescopic rod 310, and the two ends of the telescopic rod 310 are respectively hinged to the column 200 and the bracket of the base assembly 100. When it is necessary to adjust the angle α between the column 200 and the base assembly 100, the telescopic rod 310 is extended or shortened to adjust the length of the telescopic rod 310, and the telescopic rod 310 is adaptively rotated; after the adjustment is completed, the length of the telescopic rod 310 is locked, thereby locking the angle α between the column 200 and the base assembly 100. This implementation method has the advantages of simple structure and convenient operation.

[0047] During specific implementation, the telescopic rod 310 can be driven to extend and retract by electric, pneumatic, hydraulic or manual power.

[0048] In addition, the antenna bracket provided in the embodiment of the present application also includes an attachment member 400. The base assembly 100 is reliably connected to the column 200 through the attachment member 400, which can provide reliable support for the column 200 and prevent the column 200 from shaking. Specifically, the attachment member 400 includes a column support member 410, and the column support member 410 includes three supporting surface parts and three curved surface parts. The two side extension surfaces of the three supporting surface parts are arranged in a prism shape. The two sides of the curved surface part are respectively connected and tangent to the two adjacent supporting surface parts. The inner circumference of the bottom of the column 200 is in contact with the three curved surface parts. In other words, the column support member 410 can be regarded as a prism shape with an overall profile that shrinks from bottom to top. The three supporting surfaces are the outer side surfaces of the prism surface, and the curved surface part is the rounded surface between the outer side surfaces of the two adjacent prism surfaces. The column support member 410 can be set as a hollow thin-walled structure, and its cross section is a triangular ring. The column support member 410 can also be set as a solid structural member.

[0049] For the convenience of description, the three supporting surface parts of the column support 410 are respectively recorded as the first supporting surface part 414, the second supporting surface part 415 and the third supporting surface part 417, and the three curved surface parts are respectively recorded as the first curved surface part, the second curved surface part 412 and the third curved surface part 413. The two sides of the first curved surface part are respectively connected to the first supporting surface part and the second supporting surface part 415, the two sides of the second curved surface part 412 are respectively connected to the second supporting surface part 415 and the third supporting surface part 417, and the two sides of the third curved surface part 412 are respectively connected to the third supporting surface part 417 and the first supporting surface part 414. Figure 1 Taking the placement orientation of the embodiment shown as an example, from bottom to top, the distances between the first curved surface portion 411, the second curved surface portion 412 and the third curved surface portion 413 gradually decrease, and the outer peripheral surfaces of the first curved surface portion 411, the second curved surface portion 412 and the third curved surface portion 413 can be regarded as surfaces composed of countless circular arc segments.

[0050] In a specific embodiment, see Figure 1, the base assembly 100 is installed on the installation object 01, and the attachment member 400 is installed with the base assembly 100. After that, the position and state of the base assembly 100 and the attachment member 400 are fixed; the angle between the installation object 01 and the horizontal plane is β. At this time, the column 200 is in the initial state before adjustment, and the angle α between the column 200 and the base assembly 100 is 90°. The axis of the column 200 is collinear with the center line of the column support 410 of the attachment member 400. This is because any cross-section of the column support 410 is a triangle, and the three vertices of any triangle are cocircular, and the orthographic projection of the inner circumference of the column 200 on the cross-section of the prism is a circle, that is, on the contact cross-section of the inner circumference of the column 200 and the column support 410, the inner circumference of the column 200 coincides with the three vertices of the column support 410, and the inner circumference of the column 200 and the column support 410 are in three-point contact. A plane is determined based on the three points, and the bottom end of the column 200 can be reliably abutted against the column support 410.

[0051] See also Figure 2 After the column 200 is adaptively adjusted, the column 200 is in a working state and is perpendicular to the horizontal plane. The center line of the column support 410 is not colinear with the axis of the column 200, but presents a certain angle. Because the first curved surface 411, the second curved surface 412 and the third curved surface 413 can all be regarded as curved surfaces including countless circular arc segments with different radial sizes, therefore, three different parts of the inner circumference of the column 200 can always contact with a certain part of the first curved surface 411, the second curved surface 412 and the third curved surface 413 respectively. In other words, the inner circumference of the column 200 is inscribed with the circular arc segments of the three curved surfaces, that is, the inner circumference of the column 200 is in point contact with different cross sections of the column support 410, and the number of point contacts is still three. According to the principle that three points determine a plane, the contact area between the column 200 and the column support 410 is on the same plane. Therefore, the bottom end of the column 200 can reliably abut against the column support 410. At this time, under the action of the gravity of the column 200 itself, the abutment of the column support 410 on the column 200 and the combined action of the telescopic rod 310 on the column 200, the six degrees of freedom of the column 200 are limited, and the column 200 and the base assembly 100 are reliably connected and are not easy to move or rotate.

[0052] Moreover, the inner circumference of the column 200 is inscribed with the arc segments of the three curved surfaces. Although in theory the tangent arcs are in point contact, in actual physical situations, due to the influence of factors such as the elastic deformation and surface roughness of the materials of the column support 410 and the column 200, the contact area will be slightly deformed, so that the contact part is not a geometric point in the strict sense, but will form a very small contact area, which is similar to the contact of a small arc segment. Therefore, the inner circumference of the column 200 and the three curved surfaces are actually in contact with three small arc segments. The contact stress between the column 200 and the column support 410 is distributed on the three small arc segments, and will not produce extreme stress concentration like point contact. When the column is subjected to external force, this contact method can better disperse the stress, so that the pressure at the contact point is relatively small; and when a certain degree of relative displacement and vibration occurs, the contact method of the small arc segment can provide a certain buffer, and is not easy to fail due to excessive local pressure, so the contact reliability is better.

[0053] It should be noted that, when the angle β between the installation object 01 and the horizontal plane is 0°, the initial state of the column 200 is also its working state. At this time, under the partial action of the column 200's own weight, the abutment of the column support 410 on the column 200, and the combined action of the telescopic rod 310 on the column 200, the six degrees of freedom of the column 200 are restricted, and the column 200 is reliably connected to the base assembly 100, and is not easy to move or rotate.

[0054] It should be understood that the radii of the three curved portions on the same cross section of the column support 410 may be equal or unequal. When the radii of the three curved portions on the same cross section of the column support 410 may be equal, the radii of the three curved portions on each cross section of the column support 410 in the direction from the top surface to the bottom surface of the column support 410 may be equal (see Figure 6 ), or gradually increase (see Figure 7 ).

[0055] See also, 3 and Figure 4 In some embodiments, the attachment member 400 further includes two relatively disposed connection units 420 , each connection unit 420 includes a horizontal plate 422 , and the bottom surface of the column support member 410 is fixedly connected to the upper surface of the horizontal plate 422 .

[0056] In this embodiment, the column support member 410 is located above the cross plate 422, and the bottom surface of the column support member 410 is fixedly connected to the plate surface of the cross plate 422. There is a large contact area between the bottom surface of the column support member 410 and the cross plate 422 of the connecting unit 420, which is beneficial to the structural stability of the column support member 410.

[0057] During specific implementation, the vertical plate 421 and the base assembly 100 can be fixedly connected by bolts, pins, welding or the like.

[0058] See also Figure 5 In some embodiments, a supporting surface portion is provided with an opening 416, and the opening 416 passes through from the top surface to the bottom surface of the column support member 410; the curved surface portions on both sides of the supporting surface portion with the opening 416 are respectively fixedly connected to two horizontal plates 422, and there is a gap between the two horizontal plates 422.

[0059] In this embodiment, by opening an opening 416 on a supporting surface, the elastic deformation ability of the column support member 410 can be improved, which is beneficial to increase the contact arc length between the column 200 and the column support member 410; in addition, the second curved surface portion and the third curved surface portion are respectively fixedly connected to the two horizontal plates 422, and there is a spacing between the two horizontal plates 422, and the opening 416 passes through the top surface to the bottom surface of the column support member 410, which can further improve the elastic deformation ability of the column support member 410, and thus help increase the contact arc length between the column 200 and the column support member 410, thereby further improving the connection reliability between the two.

[0060] In some embodiments, the pillar support 410 and / or the connecting unit 420 are an integrally formed structure, ensuring that the attachment member 400 has a high structural stability.

[0061] See also Figure 5 In some embodiments, each connection unit 420 further includes a vertical plate 421, and the vertical plate 421 is vertically fixedly connected to the bottom of the horizontal plate 422;

[0062] The base assembly 100 includes four support rods 110, which are arranged to form a rectangular structure parallel to the installation object 01. Two adjacent support rods 110 are connected by a connecting pair of plates. The structure of the base assembly 100 is stable, which is beneficial to the structural stability of the antenna bracket. The connecting pair of plates includes two oppositely arranged connecting sub-plates 111, and each connecting sub-plate 111 is fixedly connected to the end of one support rod 110.

[0063] A connecting pair of plates corresponds to the attachment member 400 , and a vertical plate 421 is fixedly connected to the corresponding connecting sub-plate 111 .

[0064] In this embodiment, the attachment member 400 is fixedly connected to the base assembly 100 by connecting the counter plate to the vertical plate 421 .

[0065] See also Figure 3 In some embodiments, among the four support rods 110, the opposite support rods 110 are connected by the reinforcing rods 120. In this way, relative movement between the four support rods 110 of the base assembly 100 is avoided, and the structural reliability, strength and stability of the base assembly 100 are further improved.

[0066] See also Figure 5 In some embodiments, the two vertical plates 421 in the attachment member 400 are connected by an assembly part, which is beneficial to improve the structural strength of the attachment member 400. The assembly part can be configured as a bolt, that is, the two vertical plates 421 are provided with through holes at corresponding positions, and the bolts are passed through the two through holes.

[0067] In some embodiments, the column 200 is configured as a retractable rod. Thus, the height of the antenna located at the top of the column 200 can be adjusted by adjusting the length of the column 200, ensuring that the antenna can adapt to different installation scenarios, which is conducive to improving the applicability of the antenna bracket.

[0068] See also Figure 6 and Figure 7 In some embodiments, the two side extension surfaces of the three supporting surface portions are arranged to be in the shape of a right prism, so that the three curved surface portions form an angle of 120°, and the three small arc segments between the column support member 410 and the inner circumference of the column 200 are evenly distributed, which is beneficial to dispersing the contact stress between the column support member 410 and the column 200, and further improving the contact reliability.
