Description

Technical Field

[0001] The invention relates to the technical field of backpack antennas, and in particular to a portable anti-interference backpack antenna. Background Art

[0002] An antenna is a converter that converts guided waves propagating on a transmission line into electromagnetic waves propagating in an unbounded medium (usually free space), or performs the opposite conversion. It is a component used to transmit or receive electromagnetic waves in radio equipment.

[0003] There are many types of antennas. In order to facilitate carrying, people have invented a backpack antenna, which is carried and moved by hand. It is extremely portable and can achieve communication in any area. When using traditional backpack antennas, they often need to be carried and moved around manually, and the antenna rod is extended too long and inconvenient to adjust, which greatly reduces the passability of the user after carrying the antenna and makes it inconvenient to move. In view of this, we propose a portable anti-interference backpack antenna. Summary of the invention

[0004] The object of the present invention is to provide a portable anti-interference backpack antenna to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a portable anti-interference backpack antenna, comprising a backpack main body, a nylon shoulder strap is symmetrically fixedly installed on the rear surface of the backpack main body, an antenna seat is fixedly installed on the upper surface of the backpack main body, and the number of the antenna seats is several groups, a buffer spring is fixedly installed on the upper surface of the antenna seat, a lifting sleeve is fixedly installed on the upper end of the buffer spring, a lifting threaded bolt is spirally inserted inside the lifting sleeve, an antenna rod body is fixedly installed on the upper end surface of the lifting threaded bolt, a clamping mechanism with an opening and closing function is provided on the outer surface of the lifting sleeve near the upper end surface, a lifting drive mechanism with an elastic function is provided on the lower end surface of the lifting threaded bolt, and a square rod mechanism with a transmission function is provided inside the lifting sleeve near the lower surface.

[0006] Preferably, the clamping mechanism includes a light rod bracket fixedly installed on the outer surface of the lifting sleeve, and a track light rod is fixedly installed inside the light rod bracket, and an arc clamping sleeve is sleeved on the outer surface of the track light rod. There are two arc clamping sleeves in total, and they are installed symmetrically.

[0007] Preferably, the inner surfaces of the arc-shaped ferrules are respectively provided with matching threads, and the other sides of the two arc-shaped ferrules are respectively provided with threaded through holes, and the threaded through holes are coaxial, and double threaded columns are spirally inserted in the threaded through holes, and the threads on the surfaces of the double threaded columns are symmetrically arranged at the middle position of the double threaded columns, and the two threads rotate in opposite directions.

[0008] Preferably, limit stops are fixedly installed on the surface positions at both ends of the double-threaded column, a drive motor is fixedly installed on the surface position of one side of the limit stop, the rotating shaft of the drive motor is fixedly connected to the double-threaded column, a motor bracket is fixedly installed on the outer surface position of the lifting sleeve, the drive motor is fixedly installed on the motor bracket, and a limit stop ring is fixedly installed on the inner surface of the lifting sleeve near the upper end.

[0009] Preferably, the lifting drive mechanism includes a spring pressure plate fixedly installed on the lower end surface of the lifting threaded bolt, and an extension spring is provided on the lower surface of the spring pressure plate, and a spring bottom plate is fixedly installed inside the lifting sleeve at the lower end of the extension spring.

[0010] Preferably, the square rod mechanism includes a square blind hole opened at the center position of the lower end surface of the lifting threaded bolt, and a transmission square rod is inserted inside the square blind hole, a bottom plate through hole is opened at the center position of the upper surface of the spring bottom plate, the transmission square rod passes through the bottom plate through hole, and a lifting motor is fixedly installed at the lower end of the transmission square rod, and the rotating shaft of the lifting motor is fixedly connected to the transmission square rod.

[0011] Preferably, the extension spring and the lifting threaded bolt are both made of antenna signal conducting material, the backpack main body is connected to the extension spring through a signal wire, and the extension spring is connected to the antenna rod body through a lifting threaded bolt.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The controllable thread fit and release with the lifting thread bolt can be achieved through the clamping sleeve mechanism. When the driving motor drives the double thread column to rotate, the two arc-shaped clamping sleeves can be displaced to both sides at the same time, so that the arc-shaped clamping sleeve and the lifting thread bolt lose thread fit, thereby realizing the opening and closing adjustment of the thread fit of the lifting thread bolt;

[0014] The lifting drive mechanism can always apply an upward driving force to the lifting thread bolt, and when the lifting thread bolt loses the thread fit with the arc-shaped sleeve, the extension spring can drive the lifting thread bolt to pop out quickly, and the extension spring can achieve a contact connection with the lifting thread bolt, so that the signal transmission between the main body and the antenna rod body can be maintained while realizing the above-mentioned active structure;

[0015] The transmission square rod in the square rod mechanism cooperates with the square blind hole, so that the lifting motor can drive the lifting thread bolt to rotate through the transmission square rod without affecting the up and down movement of the lifting thread bolt;

[0016] The above structure allows the antenna pole to be freely adjusted in height, which reduces interference of the pole with the user's movements when the user carries the antenna on his back. When necessary, the antenna pole can be instantly extended to the highest position to improve signal reception strength. BRIEF DESCRIPTION OF THE DRAWINGS

The rotating shaft of the drive motor 506 is fixedly connected to the double-threaded column 505. A motor bracket 507 is fixedly installed on the outer surface position of the lifting sleeve 5, and the drive motor 506 is fixedly installed on the motor bracket 507. A limit stop ring 509 is fixedly installed on the inner surface of the lifting sleeve 5 near the upper end. The limit stop ring 509 can prevent the lifting threaded bolt 6 from detaching from the lifting sleeve 5 after reaching the limit position, thereby blocking the spring pressure plate 601.

[0026] The lifting drive mechanism includes a spring pressure plate 601 fixedly installed on the lower end surface of the lifting threaded bolt 6.

When it is necessary to adjust the height of the antenna rod body 7, by applying current to the lifting motor 607, the lifting motor 607 runs forward and reverse, and the lifting motor 607 drives the transmission square rod 605 to rotate, and the transmission square rod 605 drives the lifting threaded bolt 6 to rotate through the square blind hole 604. Since the arc-shaped ferrule 503 is in a clamped state at this time, the matching The mating thread 504 is screwed together with the lifting thread bolt 6, so that the lifting thread bolt 6 moves up and down, and the lifting thread bolt 6 will drive the antenna pole body 7 to adjust the height. When the road is flat and there is no external object interfering with the antenna pole body 7, the driving motor 506 can be powered on and controlled so that the driving motor 506 drives the double-thread column 505 to rotate, so that the arc-shaped sleeve 503 moves apart to both sides at the same time, and the lifting thread bolt 6 loses the threaded cooperation with the mating thread 504. Therefore, it will be driven upward and popped out quickly under the pressure of the extension spring 602, so that the antenna pole body 7 instantly reaches the optimal height, thereby enhancing the signal interaction strength.
