DETAILED DESCRIPTION

[0009] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0010] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here. In addition, the "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally represents that the objects associated with each other are in an "or" relationship.

[0011] The spotlight antenna provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0012] refer to Figures 1 to 9 The embodiment of the present application discloses a spotlight antenna, which includes a lamp tube 100, a protective cover 200, a lens 300 and a radiator 400. The radiator 400 is arranged in the lamp tube 100. The radiator 400 is located in the accommodating cavity of the lamp tube 100, that is, the radiator 400 is arranged on the inner wall of the lamp tube 100. Optionally, the radiator 400 can be arranged on the bottom wall of the lamp tube 100 or on the side wall of the lamp tube 100, and no specific limitation is made here. The lens 300 is arranged on the protective cover 200, that is, the lens 300 and the protective cover 200 are modularly arranged. In the process of installing the spotlight antenna, the radiator 400 can be first installed in the accommodating cavity of the lamp tube 100, and then the lens 300 can be installed on the protective cover 200, and then the lens 300 and the protective cover 200 can be installed on the lamp tube 100 together. At this time, the protective cover 200 and the lamp tube 100 are detachably connected so that the lens 300 faces the radiator 400. When the electromagnetic wave radiated by the radiator 400 passes through the lens 300, the lens 300 converts the spherical wave or cylindrical wave of the point source or line source into a plane wave, thereby obtaining a pencil-shaped, fan-shaped or other shaped electromagnetic wave beam, which is emitted toward the protective cover 200 and passes through the protective cover 200 to be emitted.

[0013] In the embodiment of the present application, when the spotlight antenna needs to be repaired, the protective cover 200 is disassembled from the lamp tube 100, and the lens 300 is removed from the lamp tube 100 together with the protective cover 200, so as to avoid the lens 300 blocking the radiator 400, the feeding structure and other components, so that the radiator 400, the feeding structure and other components are exposed, thereby facilitating the maintenance personnel to perform maintenance. Therefore, the embodiment of the present application can solve the problem of the difficulty in repairing the spotlight antenna at present.

[0014] In an optional embodiment, the protective cover 200 includes a detachably connected cover plate 210 and a bracket 220, and the lens 300 is detachably connected to the bracket 220, that is, the cover plate 210 and the bracket 220 and the lens 300 and the bracket 220 are both detachably connected, which is convenient for later disassembly, maintenance and replacement. Of course, the bracket 220 and the cover plate 210 can also be fixedly connected.

[0015] Optionally, the bracket 220 may be an integrated structure; or, the bracket 220 may be a split structure, and the bracket 220 includes at least two deformable members 221, each of which is disposed on the cover plate 210, and each of which is arranged at intervals around the lens 300, and each of which abuts against the peripheral surface of the lens 300, so that each of the deformable members 221 is deformed to clamp the lens 300. In this solution, the bracket 220 is composed of a plurality of separately disposed deformable members 221, and at this time, the size of each of the deformable members 221 can be set smaller, thereby reducing the space occupied, so that the structures disposed in the accommodating cavity of the lamp tube 100 are more compact, which is conducive to reducing the volume of the spotlight antenna; in addition, since the bracket composed of a plurality of deformable members 221 fixes the lens 300 by clamping, it is possible to avoid opening other types of connection structures such as connection holes on the lens 300, thereby facilitating the processing and manufacturing of the lens 300. Of course, the bracket 220 and the lens 300 may also be connected by snap-fit ​​connection or other methods.

[0016] Optionally, when the number of deformable members 221 changes, the arrangement of each deformable member 221 may be different accordingly, for example: when the number of deformable members 221 is two, each deformable member 221 is arranged in a straight line, and each deformable member 221 is clamped from two opposite sides of the lens 300; when the number of deformable members 221 is three, each deformable member 221 is arranged in an equilateral triangle; when the number of deformable members 221 is four, each deformable member 221 is arranged in a square layer. The number of deformable members 221 can be selected according to actual needs, and the embodiment of the present application does not impose any specific restrictions on this.

[0017] In a further optional embodiment, each deformable member 221 is a plate-shaped structure, and each deformable member 221 includes a connected connecting portion 221a and an abutting portion 221b, the connecting portion 221a is detachably connected to the cover plate 210 to facilitate the disassembly and assembly of the deformable member 221, and the abutting portion 221b is bent relative to the connecting portion 221a, and optionally, the angle between the connecting portion 221a and the abutting portion 221b can be less than 90°, in which case the connecting portion 221a is opposite to the abutting portion 221b; or, the connecting portion 221a The angle between the abutting portion 221b and the abutting portion 221b is greater than 90°. When the abutting portion 221b abuts against the peripheral surface of the lens 300, the abutting portion 221b is close to the connecting portion 221a, causing the deformable member 221 to deform. The connecting portion 221a is located on the side of the abutting portion 221b away from the center of the lens 300. This can prevent the connecting portion 221a from interfering with the installation of the lens 300 and the transmission of electromagnetic waves. In addition, each deformable member 221 in the present scheme is a plate-like structure, which has a simple structure and is easy to manufacture.

[0018] Optionally, the angle between the connecting portion 221a and the abutting portion 221b may be 100-110°, which may be selected according to actual needs, and the embodiment of the present application does not impose any specific limitation on this.

[0019] Optionally, the length of the abutting portion 221b may be much greater than that of the connecting portion 221a, that is, the length of the connecting portion 221a is smaller, thereby avoiding that the connecting portion 221a occupies a larger space in the radial direction of the cover plate 210, so as to reduce the width of the spotlight antenna.

[0020] Optionally, the side of the abutment portion 221b facing the lens 300 can directly contact the lens 300, and the two can be in point contact; or, in other embodiments, the abutment portion 221b is provided with an abutment surface 221b1, and the abutment surface 221b1 is fitted with the peripheral surface of the lens 300 for positioning cooperation. At this time, since the abutment portion 221b and the lens 300 are in surface contact, the contact area between the two is large, which is beneficial to improving the positioning stability between the abutment portion 221b and the lens 300. Optionally, the abutment portion 221b is also provided with a hollow area 221b2 spaced apart from the abutment surface 221b1, and the hollow area 221b2 and the abutment surface 221b1 are arranged sequentially in a direction away from the connecting portion 221a. The hollow area 221b2 can reduce the weight of the deformable member 221 to facilitate the installation of the protective cover 200 and the lens 300 to the lamp tube 100, and can save the manufacturing material of the deformable member 221.

[0021] Optionally, the abutment portion 221b includes a first plate segment, a second plate segment and a third plate segment connected in sequence, the first plate segment is connected to the connecting portion 221a, the abutment surface 221b1 is arranged on the third plate segment, the width of the first plate segment and the width of the third plate segment are both greater than the width of the second plate segment, and the width of the first plate segment is set to be larger so as to increase the connection strength between the abutment portion 221b and the connecting portion 221a, and the width of the third plate segment is set to be larger. At this time, the size of the abutment surface 221b1 can be increased, thereby improving the stability of the positioning fit between the abutment portion 221b and the lens 300. In an optional embodiment, the lens 300 is a spherical structure, and the side of the abutment portion 221b facing the lens 300 may be provided with an arcuate concave surface, which is adapted to the surface of the lens 300 for positioning and matching, and the arcuate surface forms an abutment surface 221b1; or, optionally, the abutment portion 221b is provided with a positioning hole 221b3, the positioning hole 221b3 is positioned and matched with the arcuate surface of the lens 300, and a portion of the lens 300 extends through the positioning hole 221b3 to the side of the abutment portion 221b away from the center of the lens 300, that is, the distance between the center of the positioning hole 221b3 and the center of the lens 300 is less than the radius of the lens 300, and the abutment portion 221b is sleeved on the lens 300 through the positioning hole 221b3, which is conducive to further improving the stability of the lens 300. At least part of the inner wall of the positioning hole 221b3 forms the above-mentioned abutting surface 221b1, that is, the abutting surface 221b1 is an annular surface, which fits the arc surface of the lens 300 to ensure a larger contact area between the abutting portion 221b and the lens 300.

[0022] Optionally, the lens 300 may be a Luneburg lens, or other types of lenses, which is not specifically limited in the embodiments of the present application.

[0023] In another optional embodiment, the spotlight antenna further includes at least two positioning members 500, each positioning member 500 is disposed on the side wall of the lamp tube 100, each positioning member 500 is located in the accommodating cavity, each positioning member 500 is arranged at intervals around the lens 300, the positioning member 500 is located between the side wall of the lamp tube 100 and the deformable member 221, and each positioning member 500 is positioned and matched with each deformable member 221 in a one-to-one correspondence. When the deformable member 221 abuts against the lens 300, the deformable member 221 is deformed in a direction away from the lens 300. At this time, the deformable member 221 is positioned by the positioning member 500, which can prevent the deformable member 221 from being excessively deformed. That is to say, the deformable member 221 is positioned and matched with the lens 300, and the positioning member 500 is positioned and matched with the deformable member 221, so as to avoid further deformation of the deformable member 221 relative to the lens 300, so as to improve the stability of the deformable member 221, which is conducive to further improving the positioning stability between the lens 300 and the deformable member 221; and when the positioning member 500 is positioned and matched with the deformable member 221, the protective cover 200 establishes a matching relationship with the lamp tube 100 through the deformable member 221 and the positioning member 500, which is conducive to increasing the connection firmness and stability between the protective cover 200 and the lamp tube 100. Of course, the positioning member 500 may not be provided. In a further optional embodiment, each deformable member 221 is a plate-like structure, and each deformable member 221 includes a connected connecting portion 221a and abutting portion 221b, the connecting portion 221a is detachably connected to the cover plate 210, the abutting portion 221b is bent relative to the connecting portion 221a, the abutting portion 221b abuts against the peripheral surface of the lens 300, and a positioning protrusion 221b4 is provided at one end of the abutting portion 221b away from the connecting portion 221a, the positioning member 500 is located between the side wall and the positioning protrusion 221b4, and each positioning member 500 can be a rigid structure; or, optionally, each positioning member 500 has a deformable portion 510, and the deformable portion 510 abuts against the positioning protrusion 221b4 to cause the deformable portion 510 to deform. When the lens 300 is installed on the bracket 220, the abutting portion 221b is deformed in a direction away from the lens 300 under the action of the lens 300, and the abutting portion 221b abuts against the lens 300 under the action of its own elastic potential energy to clamp the lens 300; when the protective cover 200 and the lens 300 are installed on the lamp tube 100, the positioning protrusion 221b4 interacts with the deformation portion 510, and the deformation portion 510 is deformed. At this time, the deformation portion 510 has the potential energy to restore the deformation, thereby applying a force to the positioning protrusion 221b4, and this force can make the abutting portion 221b further clamp the lens 300, thereby improving the stability of the lens 300.

[0024] Optionally, each positioning member 500 may be an elastic member; or, in another embodiment, each positioning member 500 includes a connected mounting plate 520 and a positioning plate 530, wherein the mounting plate 520 is connected to the side wall, and the two are in close contact with each other, thereby increasing the connection area between the positioning member 500 and the lamp tube 100, so as to improve the connection stability and firmness of the positioning member 500. Optionally, the positioning plate 530 includes a connected supporting portion 531 and a deforming portion 510, wherein an avoidance opening 532 is provided between the deforming portion 510 and the supporting portion 531, and a weight-reducing hole 531a is provided on the supporting portion 531 to reduce the weight of the positioning member 500, thereby facilitating the installation of the positioning member 500 and saving the manufacturing cost of the positioning member 500. Optionally, the thickness direction of the positioning plate 530 can be parallel to the thickness direction of the abutment 221b, or the positioning plate 530 can be parallel to the central axis of the accommodating cavity, that is, the thickness direction of the positioning plate 530 is perpendicular to the thickness direction of the abutment 221b, and the side of the positioning plate 530 abuts against the side of the abutment 221b away from the center of the lens 300. At this time, the size of the positioning plate 530 can be increased, thereby improving the structural strength of the positioning plate 530, and at the same time, there will be no interference between the positioning plate 530 and the inner wall of the lamp tube 100.

[0025] When the abutting portion 221b abuts against the lens 300 and the deformable portion 510 abuts against the positioning protrusion 221b4, the deformable portion 510 deforms and the width of the avoidance opening 532 becomes smaller, that is, the avoidance opening 532 provides a deformation space for the deformable portion 510 to deform freely.

[0026] In another optional embodiment, the cover plate 210 is provided with at least two groups of mounting hole groups 211, and each mounting hole group 211 is arranged at intervals along the circumference of the cover plate 210. Optionally, each mounting hole group 211 is evenly arranged along the circumference of the cover plate 210, that is, the distance between adjacent mounting hole groups 211 is equal. The spotlight antenna also includes at least two connecting members 600, each mounting hole group 211 and each connecting member 600 is arranged in a one-to-one correspondence with each deformable member 221, each mounting hole group 211 includes a first mounting hole 211a and a second mounting hole 211b arranged at radial intervals along the cover plate 210, the first mounting hole 211a is close to the edge of the cover plate 210, one end of the connecting member 600 passes through the first mounting hole 211a to be connected to the deformable member 221, in a direction perpendicular to the cover plate 210, there is a first distance between the lens 300 and the radiator 400; or, one end of the connecting member 600 passes through the second mounting hole 211b to be connected to the deformable member 221, in a direction perpendicular to the cover plate 210, there is a second distance between the lens 300 and the radiator 400, wherein the first distance is greater than the second distance.

[0027] Specifically, when the size of the lens 300 is determined, when one end of the connecting member 600 passes through the first mounting hole 211a to be connected to the deformable member 221, since the first mounting hole 211a is close to the edge of the cover plate 210, the lens 300 is closer to the cover plate 210 at this time. Therefore, after the protective cover 200 and the lens 300 are installed to the lamp tube 100, the distance between the lens 300 and the radiator 400 in the accommodating cavity is larger; when one end of the connecting member 600 passes through the second mounting hole 211b to be connected to the deformable member 221, since the second mounting hole 211b is close to the center of the cover plate 210, the lens 300 is farther from the cover plate 210 at this time. Therefore, after the protective cover 200 and the lens 300 are installed to the lamp tube 100, the distance between the lens 300 and the radiator 400 in the accommodating cavity is smaller. Since the distance between the lens 300 and the radiator 400 will affect the radiation performance of the spotlight antenna, in practical applications, it can be selected according to actual work needs, so that one end of the connector 600 passes through the first mounting hole 211a or the second mounting hole 211b and is connected to the deformable member 221, thereby determining the distance between the lens 300 and the radiator 400 to improve the radiation performance of the spotlight antenna. Of course, each mounting hole group 211 can also include a third mounting hole, a fourth mounting hole, etc. In the radial direction of the cover plate 210, the first mounting hole 211a, the second mounting hole 211b, the third mounting hole and the fourth mounting hole are arranged in sequence, so as to provide more options for the installation position of the lens 300.

[0028] Optionally, the number of the first mounting hole 211a and the second mounting hole 211b can be one, or the number of the first mounting hole 211a and the second mounting hole 211b can be at least two, and the first mounting holes 211a are arranged in sequence and at intervals, and the distances between the first mounting holes 211a and the center of the cover plate 210 are equal. Similarly, the second mounting holes 211b are arranged in sequence and at intervals, and the distances between the second mounting holes 211b and the center of the cover plate 210 are equal, so as to facilitate the setting of the deformable member 221. This solution is conducive to improving the connection firmness between the deformable member 221 and the cover plate 210 by setting a plurality of first mounting holes 211a and second mounting holes 211b.

When it is necessary to adjust the pitch angle of the lamp tube 100, the fastener 800 can be loosened first, and then the inclination angle of the lamp tube 100 can be adjusted. At this time, the lamp tube 100 rotates together with the protective cover 200. After the angle adjustment of the lamp tube 100 is completed, the fastener 800 is then tightened to fix the lamp tube 100 relative to the mounting frame 700. This solution can flexibly adjust the radiation field direction of the spotlight antenna according to actual needs to increase the coverage of the radiation field, thereby improving the utilization rate of the spotlight antenna.

Optionally, the connecting frame 120 is further provided with a through hole spaced apart from the arc hole 121, and the through hole is located below the arc hole 121, that is, the through hole is provided close to the bottom plate 720.
