Description

Technical Field

[0001] This invention relates to the field of antenna technology, and in particular to an impact-resistant full-wave dipole antenna structure. Background Technology

[0002] Currently, due to the rapid development of wireless signals, there is a large demand for indoor and outdoor user receiving antennas. Since rainwater can affect the antenna's lifespan after entering the antenna element, ABS engineering plastic is used to integrally inject the microstrip circuit board and the joint of the two interface circular tubes welded by argon arc welding to achieve an effective waterproof effect.

[0003] However, in existing technologies, antenna structures lack the ability to resist shock and vibration during use, resulting in a significant reduction in the antenna's lifespan. Summary of the Invention

[0004] The purpose of this invention is to provide an impact-resistant full-wave dipole antenna structure, which aims to solve the technical problem that the antenna structure in the prior art does not have the ability to resist impact and reduce vibration during use, resulting in a significant reduction in the service life of the antenna.

[0005] To achieve the above objectives, the present invention employs an impact-resistant full-wave dipole antenna structure, comprising a base, an radome, a lower dipole, an upper dipole, a damping pad, a damping ring, and a damper. The lower dipole is disposed at one end of the base, the radome is disposed at one end of the base, and the lower dipole is disposed inside the radome. The damping ring is disposed inside the radome. The damper is fixedly connected to the damping ring and is located inside the radome. The upper dipole is disposed at one end of the damper, and the damping pad is disposed at one end of the upper dipole and is located inside the radome.

[0006] The shock-resistant full-wave dipole antenna structure also includes a connector, which is fixedly connected to the lower dipole and located at one end of the lower dipole.

[0007] The damper includes a ball bearing, a housing, a spring, and a set screw. The housing is fixedly connected to the damping ring and located inside the radome. The set screw is threadedly connected to the housing and located inside the housing. The ball bearing is located at the other end of the housing away from the set screw. The spring is located inside the housing and between the set screw and the ball bearing. The lower vibrator is threadedly connected to the set screw and located below the set screw. The upper vibrator is threadedly connected to the ball bearing and located above the ball bearing.

[0008] The base includes a sheath, an eccentric sleeve, an open cone, a frustum, and anti-rotation pins. The frustum is fixedly connected to the open cone and located inside the open cone. The lower vibrator passes through the frustum. The sheath is fixedly connected to the open cone and located on the outer wall of the open cone. The radome is disposed between the open cone and the sheath. The eccentric sleeve is disposed between the radome and the sheath. There are multiple anti-rotation pins, each of which passes through the sheath and the eccentric sleeve and is threadedly connected to the radome.

[0009] The open cone includes a cone plate, a cone body, and fixing bolts. The cone body is fixedly connected to the cone plate and is located on one side of the cone plate. The cone body is disposed between the radome and the cone platform. There are multiple bolts, each of which passes through the cone plate and is threadedly connected to the sheath.

[0010] The radome is made of 2mm thick fiberglass material.

[0011] The beneficial effects of the impact-resistant full-wave dipole antenna structure of the present invention are as follows: the choke structure adopts a screw connection method, which facilitates electrical adjustment at any position, simplifies assembly, ensures precise positioning, and provides reliable locking. Furthermore, it does not require additional custom-made special materials, reducing processing costs. The damping pads, damping rings, and dampers can effectively reduce the buffering force of the upper and lower dipoles, and achieve effective impact resistance without increasing the size and weight of the antenna bottom, thus realizing the lightweight design of the antenna.

Furthermore, in the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0020] Please see Figures 1 to 4 This invention provides an impact-resistant full-wave dipole antenna structure, including a base, an radome 1, a lower dipole 2, an upper dipole 3, a damping pad 4, a damping ring 5, and a damper. The lower dipole 2 is disposed at one end of the base, the radome 1 is disposed at one end of the base, and the lower dipole 2 is disposed inside the radome 1. The damping ring 5 is disposed inside the radome 1. The damper is fixedly connected to the damping ring 5 and is located inside the radome 1. The upper dipole 3 is disposed at one end of the damper, and the damping pad 4 is disposed at one end of the upper dipole 3 and is located inside the radome 1.

[0021] Furthermore, the shock-resistant full-wave dipole antenna structure also includes a connector 6, which is fixedly connected to the lower dipole 2 and located at one end of the lower dipole 2.

[0022] Furthermore, the damper includes a ball bearing 7, a housing 8, a spring 9, and a set screw 10. The housing 8 is fixedly connected to the damping ring 5 and is located inside the radome 1. The set screw 10 is threadedly connected to the housing 8 and is located inside the housing 8. The ball bearing 7 is disposed at the other end of the housing 8 away from the set screw 10. The spring 9 is disposed inside the housing 8 and is located between the set screw 10 and the ball bearing 7. The lower vibrator 2 is threadedly connected to the set screw 10 and is located below the set screw 10. The upper vibrator 3 is threadedly connected to the ball bearing 7 and is located above the ball bearing 7.

[0023] Furthermore, the base includes a sheath 11, an eccentric sleeve 12, an open cone, a frustum 13, and anti-rotation pins 14. The frustum 13 is fixedly connected to the open cone and located inside the open cone. The lower vibrator 2 passes through the frustum 13. The sheath 11 is fixedly connected to the open cone and located on the outer wall of the open cone. The radome 1 is disposed between the open cone and the sheath 11. The eccentric sleeve 12 is disposed between the radome 1 and the sheath 11. There are multiple anti-rotation pins 14, each of which passes through the sheath 11 and the eccentric sleeve 12 and is threadedly connected to the radome 1.

[0024] Furthermore, the open cone includes a cone plate 15, a cone body 16, and a fixing bolt 17. The cone body 16 is fixedly connected to the cone plate 15 and is located on one side of the cone plate 15. The cone body 16 is disposed between the antenna cover 1 and the cone 13. There are multiple bolts, each of which passes through the cone plate 15 and is threadedly connected to the sheath 11.

[0025] Furthermore, the radome 1 is made of 2mm thick fiberglass material.

[0026] In this invention, the internal vibration reduction of the antenna is achieved through the damper, which can achieve the required strength without increasing the size and weight of the antenna bottom, and also achieves the weight reduction of the antenna. The damping can be adjusted between the set screw 10 and the housing 8. When the antenna is subjected to vibration or shock wave, the spring 9 in the damper can play an effective buffering role and absorb the vibration, thereby preventing the upper vibrator 3 and the lower vibrator 2 from bending and deforming.

[0027] The radome 1 is made of 2mm thick fiberglass material, which ensures the strength and rigidity of the radome 1 itself. The radome 1 is a thin-walled component, and increasing the thickness of the radome 1 will affect the electrical performance. The radome 1 is limited by its shape and connection method, and there is no flip-up flange at the bottom. The conventional connection method is to insert the radome 1 into the inside of the sheath 11 and fill the gap with adhesive. In this invention, the gap between the radome 1 and the sheath 11 is eliminated by using the eccentric sleeve 12, and the radome 1 is fixed on the side wall of the sheath 11 by the anti-rotation pin 14, which restricts the degree of freedom of the radome 1. The cone 16 is deformed and collided by the extrusion of the frustum 13, so that the connection gap between the radome 1 and the open cone reaches an interference fit, thereby fixing the radome 1. The cone 16 is fixed to one side of the cone plate 15 by the fixing bolt 17.

[0028] The above description discloses only one preferred embodiment of the present invention, and should not be construed as limiting the scope of the present invention. Those skilled in the art will understand that all or part of the processes of the above embodiments can be implemented, and equivalent changes made in accordance with the claims of the present invention are still within the scope of the invention.
