However, it should be understood that the present application can be presented in many different ways and is not limited to the embodiments described below. It should also be understood that the embodiments disclosed in the present disclosure may be combined in various ways so as to provide more additional embodiments. In all the attached drawings, the same reference signs may represent the same or functionally identical elements.
In the illustrated embodiment, the upper mounting support 40a and the lower mounting support 40b may be constructed the same or similarly. When they are constructed similarly, they can have different geometric parameters. For example, their first sections, which will be mentioned below, can have different lengths. In embodiments not shown, the upper mounting support 40a and the lower mounting support 40b may also be differently constructed. For example, the upper mounting support 40a may be a plate-like component, and the lower mounting support 40b may be a rod component.
The upper support member 40a may include a first section 41a. The first section 41a is configured to, in a mounted state of the base station antenna 10 and the holding pole 20, connect with the inner side 11 of the base station antenna 10 facing the holding pole 20 in the upper end section of the base station antenna 10. For example, the first section 41a can be connected to the inner side 11 of the base station antenna 10 at its free end, and thus the first section 41a is constituted as a cantilever. For this reason, in the upper end section of the base station antenna 10, the inner side 11 of the base station antenna 10 may have an upper connecting structure 15a. The first section 41a can be fastened on the connecting structure 15a. The connecting structure 15a may comprise a plurality of screw bolts fastened to the radome of the base station antenna, and the first section may comprise a plurality of mounting holes, through which the screw bolts can penetrate, and then respective nuts can be tightened onto the screw bolts, and thus the first section 41a is fastened on the radome. The first section 41a may extend parallel to the longitudinal direction of the base station antenna 10, wherein the first section 41a may extend parallel to or may abut against the flat inner side 11 of the base station antenna 10 at a very small distance. The first section 41a may be a plate-like component. For the purpose of reducing weight, the first section 41a may be provided with an array of holes.
The upper support member 40a may include a second section 42a. The second section is configured to, in the mounted state of the base station antenna 10 and the holding pole 20, extend from the first section 41a in a direction away from the holding pole 20 and extend beyond the end side 13 of the upper end section of the base station antenna 10 in a longitudinal direction of the base station antenna 10. Advantageously, the second section 42a may extend parallel to the upper end side 13 of the base station antenna 10. In particular, the second section 42a does not extend beyond the outer side 12 of the base station antenna 10 facing away from the holding pole 20 in the radial direction. The second section 42a may be a plate-like component. The second section 42a may be bent approximately 90° relative to the first section 41a.
The upper support member 40a may include a connecting portion 43a, which is connected with the second section 42a. The connecting portion 43a may be configured to be directly or indirectly connected with the holding pole 20 in the mounted state of the base station antenna 10 and the holding pole 20. Advantageously, the connecting portion 43a extends from the second section 42a in a direction away from the base station antenna 10, and the connecting portion 43a may be bent approximately 90° relative to the second section.
The three upper support members 40a can be connected to the holding pole 20 through a common structural assembly 50a, and this structural assembly is fastened to the holding pole 20. The structural assembly 50a will be described in more detail later.
In order to improve the overall stability of the three base station antennas 10 connected to the holding pole 20 by the three support members 40a, the first section 41a of the three support members 40a may have two opposing connecting members 44a, respectively. Each two adjacent support members 41a may be mutually connected through their two adjacent connecting members 44a, for example, through the connection of bolts, so that the three support members 41a can form a ring surrounding the holding pole 20, thus improving the overall strength of the three support members 40a.
The lower support member 40b may include a first section 41b. The first section 41b is configured to, in the mounted state of the base station antenna 10 and the holding pole 20, connect with the inner side 11 of the base station antenna 10 facing the holding pole 20 in the lower end section of the base station antenna 10. For example, the first section 41b can be connected to the inner side 11 of the base station antenna 10 at its free end, and thus the first section 41b is constituted as a cantilever. For this reason, in the lower end section of the base station antenna 10, the inner side 11 of the base station antenna 10 may have a lower connection structure 15b. The first section 41b can be fastened on the connecting structure 15b in a manner similar to fixing the first section 41a on the connecting structure 15a. The first section 41b may extend parallel to the longitudinal direction of the base station antenna 10, wherein the first section 41b may extend parallel to or may abut against the flat inner side 11 of the base station antenna 10 at a very small distance. The first section 41b may be a plate-like component. For the purpose of reducing weight, the first section 41b may be provided with an array of holes.
The lower support member 40b may include a second section 42b. The second section is configured to, in the mounted state of the base station antenna 10 and the holding pole 20, extend from the first section 41b in a direction away from the holding pole 20 and extend beyond the end side 14 of the lower end section of the base station antenna 10 in the longitudinal direction of the base station antenna 10. Advantageously, the second section 42b may extend parallel to the lower end side 14 of the base station antenna 10. In particular, the second section 42b does not extend beyond the outer side 12 of the base station antenna 10 facing away from the holding pole 20 in the radial direction. The second section 42b may be a plate-like component. The second section 42b may be bent approximately 90° relative to the first section 41b.
The lower support member 40b may include a connecting portion 43b, which is connected with the second section 42b. The connecting portion 43b may be configured to be directly or indirectly connected with the holding pole 20 in the mounted state of the base station antenna 10 and the holding pole 20. Advantageously, the connecting portion 43b extends from the second section 42b in a direction that faces away from the base station antenna 10, and the connecting portion 43b may be bent approximately 90° relative to the second section 42b.
The three lower support members 40b can be connected to the holding pole 20 through a common structural assembly 50b, and the structural assembly 50b is fastened to the holding pole 20. With regard to the structural component 50b, it will be described in more detail below.
In order to improve the overall stability of the three base station antennas 10 connected to the holding pole 20 by the three support members 40b, the first section 41b of the three support members 40b may have two opposing connecting members 44b, respectively. Each two adjacent support members 41b may be mutually connected through their two adjacent connecting members 44b, for example, through the connection of bolts, so that the three support members 41b can form a ring surrounding the holding pole 20, thus improving the overall strength of the three support members 40b.
