[0025] In order to more clearly understand the above-mentioned objects, features and advantages of the present application, the solutions of the present application will be further described below. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0026] Many specific details are set forth in the following description in order to provide a thorough understanding of the present application, but the present application may be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present application, rather than all the embodiments.

[0027] For the existing point-supporting support bridge, when supporting an antenna, multiple support bridges are often required, which not only occupy the internal space of the radome, but also have poor support effect. At the same time, in order to fix the radome, a card seat is also required when using the support bridge, increasing the use of materials; in order to solve the problem of poor point-supporting effect, a surface-supporting support bridge has been designed, but the existing surface-supporting support bridge can only support a radome with a specific size, and support bridges of different sizes cannot share a pair, so the versatility is poor.

[0028] As Figures 1 to 4 described, to solve the above technical problems, the embodiment of the present application provides an adjustable-size support bridge 1, including a support body 10 and a first support section 20 located at both ends of the support body 10. The support body 10 is strip-shaped, and the outer surface of the support body 10 is an outer support surface that is consistent with the inner wall contour of the radome, so as to ensure that the outer support surface of the support body 10 can fit with the inner wall of the radome.

[0029] Two first support segments 20 are located on the same side of the support body 10 and intersect with the support body 10. The outer surface of the first support segment 20 and the support body 10 at the intersection is an arc surface. The support body 10 includes a second support segment 101 and a third support segment 102 arranged in sequence along the length direction. The second support segment 101 and the first support segment 20 connected thereto are of an integral structure, and the third support segment 102 and the first support segment 20 connected thereto are of an integral structure. A first clamping portion is provided at one end of the second support segment 101 away from the first support segment 20, and a second clamping portion cooperating with the first clamping portion is provided at one end of the third support segment 102 away from the first support segment 20. The number of the first clamping portions and / or the second clamping portions is multiple, and the multiple first clamping portions or the multiple second clamping portions are arranged in sequence along the length direction of the support body 10. The first clamping portions with different numbers and different positions cooperate with the second clamping portions with different numbers and different positions to realize the adjustment of the length of the support body 10, and thus it can be applicable to radomes with different cross-sectional widths.

[0030] Exemplarily, the number of the first clamping portions is 3, and the number of the second clamping portions is 1. When the second clamping portion cooperates with different first clamping portions, the formed lengths of the support body 10 are different.

[0031] Further, in some embodiments of the present application, the first clamping portion includes a first buckle 50, the second clamping portion includes a first buckle hole 30 that is clamped and cooperated with the first buckle 50, and the first buckle 50 and the first buckle hole 30 are clamped and cooperated along the direction perpendicular to the length direction of the support body 10. Specifically, the first buckle 50 is inserted into the first buckle hole 30 along the direction perpendicular to the length direction of the support body 10 and is locked by the first buckle hole 30, so as to realize the interlocking of the second support segment 101 and the third support segment 102, and the length of the support body 10 is fixed. When the length of the support body 10 needs to be adjusted, the first buckle 50 is disengaged from the first buckle hole 30, the first buckle 50 and the first buckle hole 30 are unlocked, and there is no mutual fixing relationship between the second support segment 101 and the third support segment 102, and they can move relatively, so that different first buckles 50 cooperate with different first buckle holes 30 to adjust the length of the support body 10.

[0032] Further, in some embodiments of the present application, the outer support surfaces of the second support segment 101 and the second support segment 101 are flush, so as to ensure that when the support bridge 1 is located in the radome, the second support segment 101 and the third support segment 102 can be simultaneously attached to the inner wall of the radome and support the radome at the same time.

[0033] Further, in some embodiments of the present application, the first buckle 50 includes a first connecting portion and a first elastic arm. The first connecting portion extends in a direction perpendicular to the length direction of the support body 10. The first end of the first elastic arm is connected to the end of the first connecting portion away from the support body 10, and the second end gradually moves away from the first connecting portion in a direction close to the support body 10. The number of the first elastic arms is multiple, and the multiple first elastic arms are arranged at intervals along the circumferential direction of the first connecting portion. When the second end of the first elastic arm is squeezed, it can move in a direction close to the first connecting portion to adjust the distance between the first elastic arm and the first connecting portion, thereby adjusting the size of the first buckle 50 in the circumferential direction.

[0034] Exemplarily, in some embodiments of the present application, the number of the first elastic arms is two. The two first elastic arms are symmetrically arranged with respect to the first connecting portion, and the two first elastic arms are arranged in a V shape on both sides of the first connecting portion. The width of the first buckle hole 30 is smaller than the distance between the second ends of the two first elastic arms. When the first buckle 50 is engaged with the first buckle hole 30, the first end of the first elastic arm first enters the first buckle hole 30. Along the direction of approaching each other, the second ends of the first elastic arms slowly enter the first buckle hole 30. The two first elastic arms are arranged in a V shape. On the one hand, it can play a guiding role when engaged with the first buckle hole 30. On the other hand, it is convenient to be deformed by extrusion to form an interlocking effect with the first buckle hole 30.

[0035] The first buckle 50 can pass through the first buckle hole 30, that is, axially pass from one side of the first buckle hole 30 to the other side of the first buckle hole 30. When the first buckle 50 reaches the other side of the first buckle hole 30, the extrusion force on the first elastic arm disappears, and the first elastic arm resets under its own elastic force to form a clamping effect with the other end of the first buckle hole 30. When it is necessary to unlock the second support section 101 and the third support section 102, manually pinch the two first elastic arms in a direction close to each other to make the distance between the second ends of the two first elastic arms smaller than the width of the first buckle hole 30, so that the first buckle 50 can be withdrawn from the first buckle hole 30 in the reverse direction.

[0036] Specifically, the number of the first elastic arms can also be 3, 4 or more, and the principle is the same as when the number of the first elastic arms is 2.

[0037] Further, in some embodiments of the present application, the second support segment 101 includes a second support body segment 101b and a second clamping and fitting segment 101a arranged in sequence along the length direction. The first clamping portion is located on the second clamping and fitting segment 101a. The second clamping and fitting segment 101a includes a first card slot 101a1 and a first snap hole 30 arranged in sequence along the direction perpendicular to the length direction of the second support segment 101. The third support segment 102 includes a second support body segment 101b and a third clamping and fitting segment 102a arranged in sequence along the length direction. The second clamping portion is located on the third clamping and fitting segment 102a. The third clamping and fitting segment 102a is inserted into the first card slot 101a1, and the second clamping portion correspondingly cooperates with the first clamping portion.

[0038] Specifically, the dimension of the first card slot 101a1 along the length direction of the support body 10 is equal to the dimension of the third clamping and fitting segment 102a along the length direction. The third clamping and fitting segment 102a is inserted into the first card slot 101a1 along the direction perpendicular to the length direction of the support body 10. In the first card slot 101a1, the second clamping portion on the third clamping and fitting segment 102a selectively cooperates with the first clamping portion at the bottom of the first card slot 101a1 to achieve the mutual locking between the second support segment 101 and the third support segment 102.

[0039] The outer support surface of the second clamping and fitting segment 101a is flush with the outer support surface of the second support body segment 101b. A step is formed between the outer support surface of the third clamping and fitting segment 102a and the outer support surface of the third support body segment 10. The thickness of the step is equal to the thickness of the wall of the first card slot 101a1. When the third clamping and fitting segment 102a is inserted into the first card slot 101a1, the outer support surface of the third support body segment 10 is flush with the outer support surface of the second clamping and fitting segment 101a.

[0040] Further, in some embodiments of the present application, one of the first clamping portion and the second clamping portion further includes a second card slot 60, and the other includes a second clamping rib 40 that cooperates with the second card slot 60. The insertion direction of the second card slot 60 and the second clamping rib 40 is the same as the insertion direction of the first snap 50 and the first snap hole 30, and the number of the second card slots 60 and / or the second clamping ribs 40 is multiple. The multiple second card slots 60 or the multiple second clamping ribs 40 are arranged at intervals along the length direction of the support body 10.

[0041] Specifically, in some embodiments of the present application, the first clamping portion includes the second clamping rib 40, the second clamping portion includes the second card slot 60, the second clamping rib 40 is arranged on the side wall of the first card slot 101a1, the length direction of the second clamping rib 40 is arranged along the axial direction of the first snap hole 30, and the second card slot 60 is arranged on the third clamping and fitting segment 102a.

[0042] Exemplarily, the number of the second clamping ribs 40 is multiple, and the number of the second clamping grooves 60 is one. When the first buckle 50 is engaged with different first buckle holes 30, the second clamping groove 60 is engaged with different second clamping ribs 40. The engagement between the second clamping rib 40 and the second clamping groove 60 guides the engagement between the first buckle 50 and the first buckle hole 30, and guides the first buckle 50 into the corresponding first buckle hole 30.

[0043] Of course, the positions of the second clamping rib 40 and the second clamping groove 60 can also be interchanged, that is, the second clamping rib 40 is arranged on the third clamping and engaging section 102a, and the second clamping groove 60 is arranged on the inner side wall of the second clamping groove 60.

[0044] In some embodiments of the present application, the number of the second clamping ribs 40 is three, and the three second clamping ribs 40 are arranged at intervals along the length direction of the support body 10 on the upper side wall of the first clamping groove 101a1. The number of the second clamping grooves 60 is three, and the three second clamping grooves 60 are arranged at intervals along the length direction of the third clamping and engaging section 102a on the upper surface of the third clamping and engaging section 102a.

[0045] Further, in some embodiments of the present application, a protrusion 20a is provided on the outer support surface of the first support section 20, and the protrusion 20a forms a flat limiting surface toward the end of the first support section 20 away from the support body 10. The setting of the limiting surface is to realize the assembly relationship between the support bridge 1 and the radome.

[0046] Further, in some embodiments of the present application, a plurality of second buckles 201 are provided at one end of the first support section 20 away from the support body 10, and the plurality of second buckles 201 are arranged staggeredly along the direction perpendicular to the length direction of the support body 10.

[0047] Specifically, in some embodiments of the present application, the structure of the second buckle 201 is the same as that of the first buckle 50. The extending direction of the second buckle 201 is perpendicular to the extending direction of the first buckle 50. The second buckle 201 extends along the length direction of the first support section 20. In the direction perpendicular to the length direction of the support body 10, the plurality of second buckles 201 are arranged at intervals, and the plurality of second buckles 201 are not arranged in sequence along the direction perpendicular to the support body 10, but are staggered in sequence in the direction perpendicular to the support body 10.

[0048] Furthermore, some embodiments of the present application provide a radome, which includes a radome body 80, a bottom plate 70 located inside the radome body 80, and an adjustable-size support bridge 1 as described in the above embodiments. The bottom plate 70 is an inherent structure of the base station antenna for installing the antenna assembly. The bottom plate 70 is provided with second snap holes for cooperating with the second snaps 201. The number of adjustable-size support bridges 1 is two, and the two support bridges 1 are respectively disposed on both sides of the bottom plate 70.

[0049] Specifically, the purpose of staggeredly arranging the second snaps 201 on the first support section 20 is to install the support bridges 1 on both sides of the bottom plate 70 respectively.

[0050] Furthermore, in some embodiments of the present application, limiting rib strips 801 are provided on the side wall of the radome body 80. The end of the bottom plate 70 is bent upward to form a flange. The flange and the protrusion 20a on the first support section 20 located above the bottom plate 70 are located on both sides of the limiting rib strips 801 and are snap-fitted and fixed with the limiting rib strips 801.

[0051] Specifically, in some embodiments of the present application, the inner wall of the radome body 80 protrudes inward to form limiting rib strips 801. The end of the bottom plate 70 is bent upward and then bent downward to form a flanging. The flanging abuts against the lower surface of the limiting rib strips 801. Exemplarily, the end of the bottom plate 70 is first bent upward and then bent downward to form an arc-shaped flanging that abuts against the lower surface of the limiting rib strips 801. The protrusion 20a on the outer support surface of the first support section 20 is located above the limiting rib strips 801, and the limiting surface on the protrusion 20a cooperates with the upper surface of the limiting rib strips 801 to realize the assembly of the support bridge 1 and the radome body 80.
