An integrated RFID low-frequency and high-frequency composite antenna structure

Abstract

This utility model discloses an integrated RFID low-frequency and high-frequency composite antenna structure, including an antenna base, an mounting bracket fixedly installed on the outer wall of the antenna base, an antenna body sleeved inside the antenna base, and a processing component disposed outside the antenna body. The processing component includes a protective component disposed outside the antenna body, and an auxiliary component disposed outside the protective component. When the antenna body is in use and encounters severe weather, the protective box is pulled down, and the locking block, which is set at an angle between the outer wall and the end of the protective box, squeezes it, causing the locking block to drive the sleeve plate to slide on the outer wall of the pole frame and compress the spring sleeved on the outer wall of the pole frame. When the locking block is aligned with the locking hole opened on the outer wall of the protective box, the sleeve plate is pushed under the elastic action of the spring, so that the locking block is engaged with the protective box. The antenna body can be protected by the protective box. Under the restriction of the retaining ring, the protective box can be precisely slid and squeezed with the angled surface of the locking block.

Description

Technical Field

[0001] This utility model relates to the field of antenna technology, specifically to an integrated RFID low-frequency and high-frequency composite antenna structure. Background Technology

[0002] An antenna is a key device that converts electrical signals into electromagnetic waves. The integrated RFID low-frequency (LF) and high-frequency (HF) composite antenna structure refers to a technical solution that uses physical integration design and circuit co-optimization to achieve compatible reception and transmission of dual-band signals by a single antenna structure, covering both low-frequency (125-134kHz) and high-frequency (13.56MHz) RFID antennas. This solves the problems of size differences, impedance matching, and electromagnetic interference between antennas of different frequency bands.

[0003] Existing integrated RFID low-frequency and high-frequency composite antennas are exposed to the outside environment during use, making them difficult to protect in severe weather and thus prone to damage.

[0004] Therefore, we propose an integrated RFID low-frequency and high-frequency composite antenna structure that can protect the exposed integrated RFID low-frequency and high-frequency composite antenna from damage and extend its service life. Utility Model Content

[0005] The purpose of this invention is to provide an integrated RFID low-frequency and high-frequency composite antenna structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an integrated RFID low-frequency and high-frequency composite antenna structure, including an antenna base, an mounting bracket fixedly installed on the outer wall of the antenna base, an antenna body sleeved inside the antenna base, and a processing component disposed outside the antenna body. The processing component includes a protective component disposed outside the antenna body, and an auxiliary component disposed outside the protective component.

[0007] Preferably, the protective assembly includes a slide rod fixedly installed on the top surface of the antenna mount, a first magnetic ring fixedly installed at the top of the slide rod, a sleeve block slidably disposed on the outer wall of the slide rod, a second magnetic ring fixedly installed on the top surface of the sleeve block, a protective box fixedly installed on the outer wall of the sleeve block, a pole frame disposed on the outside of the protective box, a retaining ring fixedly installed on the outer wall of the pole frame, a sleeve plate slidably disposed on the outer wall of the pole frame, a spring fixedly installed on the side wall of the sleeve plate, and a locking block fixedly installed on the side of the sleeve plate away from the spring.

[0008] Preferably, the auxiliary component includes a frame fixedly installed on the outer wall of the antenna mount, a first magnetic frame fixedly installed on the inner wall of the frame, a second magnetic frame slidably disposed inside the frame, and a protective frame fixedly installed on the side wall of the second magnetic frame.

[0009] Preferably, the end of the locking block away from the sleeve plate is set at an angle, and the outer wall of the locking block engages with the locking hole opened on the outer wall of the protective box. The locking block with the angled end can make the protective box and the locking block be smoothly pressed and engaged.

[0010] Preferably, the end of the pole is fixedly installed to the top surface of the antenna base. There are two sets of poles, which are symmetrically distributed around the center line of the top surface of the antenna base. Under the constraint of the poles, the sleeve plate can be stably supported and slid.

[0011] Preferably, the second magnetic ring is slidably disposed inside the outer wall of the slide bar, and the second magnetic ring and the first magnetic ring are magnetically attracted to each other. Under the restriction of magnetic attraction, the protective box is stably placed above the antenna body.

[0012] Preferably, the first magnetic frame and the second magnetic frame are magnetically attracted to each other, and the outer wall of the protective frame is slidably disposed with respect to the inside of the frame. Under the restriction of magnetic attraction, the protective frame and the frame can stably protect the connection between the wire harness and the antenna mount.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This integrated RFID low-frequency and high-frequency composite antenna structure comprises a protective component. When the antenna body encounters severe weather during use, pulling the protective box downwards causes a locking block, positioned at an angle on the outer wall and end of the protective box, to press against it. This locking block causes a sleeve plate to slide against the outer wall of the pole, compressing a spring fitted onto the outer wall of the pole. When the locking block aligns with a locking hole on the outer wall of the protective box, the spring's elasticity pushes the sleeve plate, engaging the locking block with the protective box. The protective box thus protects the antenna body. The retaining ring ensures precise sliding between the protective box and the angled locking block. The operator can observe whether the antenna body is damaged through the observation window fixed inside the protective box. When the antenna body does not need protection, pull the sleeve plate so that the locking block is no longer locked to the protective box. Pull the protective box upward so that the sleeve block slides on the outer wall of the sliding rod. Under the magnetic attraction between the second magnetic ring and the first magnetic ring, the sleeve block can be stably placed above the antenna body, and the antenna body can work normally. This structure can quickly protect the antenna body and avoid damage to it (the antenna body is an integrated RFID low-frequency and high-frequency composite antenna, which is a known technology, so its structure is not fully described).

[0015] 2. This integrated RFID low-frequency and high-frequency composite antenna structure consists of auxiliary components. When the antenna body is in use, the connecting wire harness is plugged into the socket on the outer wall of the antenna base. To prevent foreign objects from colliding with the connection between the wire harness and the antenna base, protection is required. At this time, the protective frame is pulled, which causes the second magnetic frame to slide outward from the frame. Under the magnetic attraction between the first and second magnetic frames, the protective frame and the frame stabilize and protect the connection, preventing foreign objects from colliding with the connection and causing signal instability.

[0023] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0024] Example 1: A preferred embodiment of the integrated RFID low-frequency and high-frequency composite antenna structure provided by this utility model is as follows: Figures 1 to 6 As shown: An integrated RFID low-frequency and high-frequency composite antenna structure, including an antenna mount 1;

[0025] The antenna mount 1 is fixedly mounted on the outer wall with a mounting bracket 2;

[0026] The antenna body 3 is housed inside the antenna mount 1;

[0027] The antenna body 3 is provided with a processing assembly 4. The processing assembly 4 includes a protective assembly 41 provided outside the antenna body 3. The protective assembly 41 includes a slide rod 411 fixedly installed on the top surface of the antenna base 1. A first magnetic ring 412 is fixedly installed on the top of the slide rod 411. A sleeve block 413 is slidably provided on the outer wall of the slide rod 411. A second magnetic ring 414 is fixedly installed on the top surface of the sleeve block 413. A protective box 415 is fixedly installed on the outer wall of the sleeve block 413. A pole frame 416 is provided on the outside of the protective box 415. A retaining ring 417 is fixedly installed on the outer wall of the pole frame 416. A sleeve plate 418 is slidably provided on the outer wall of the pole frame 416. A spring 419 is fixedly installed on the side wall of the sleeve plate 418. A locking block 420 is fixedly installed on the side of the sleeve plate 418 away from the spring 419.

[0028] In this embodiment, when the antenna body 3 is in use and encounters severe weather, the protective box 415 is pulled downwards. The outer wall of the protective box 415 and the end of the inclined locking block 420 are pressed together, causing the locking block 420 to drive the sleeve plate 418 to slide on the outer wall of the pole frame 416 and compress the spring 419 sleeved on the outer wall of the pole frame 416. When the locking block 420 is aligned with the locking hole on the outer wall of the protective box 415, the sleeve plate 418 is pushed under the elastic action of the spring 419, so that the locking block 420 is engaged with the protective box 415. The protective box 415 can protect the antenna body 3. Under the restriction of the retaining ring 417, the protective box 415 can be precisely slid and pressed against the inclined surface of the locking block 420. Personnel can observe whether the antenna body 3 is damaged through the observation window fixedly installed inside the protective box 415. When the antenna body 3 does not need to be protected, pull the sleeve plate 418 so that the locking block 420 is no longer locked with the protective box 415. Pull the protective box 415 upward so that the sleeve block 413 slides on the outer wall of the slide rod 411. Under the magnetic attraction between the second magnetic ring 414 and the first magnetic ring 412, the sleeve block 413 can be stably placed above the antenna body 3, and the antenna body 3 can work normally. This structure can quickly protect the antenna body 3 and avoid its damage (the antenna body 3 is an integrated RFID low-frequency and high-frequency composite antenna, which is a known technology, so its structure is not fully described).

[0029] Furthermore, the end of the locking block 420 away from the sleeve plate 418 is set with an angle, and the outer wall of the locking block 420 is engaged with the locking hole opened on the outer wall of the protective box 415. The locking block 420 with the angled end can make the protective box 415 and the locking block 420 be smoothly pressed and engaged.

[0030] Furthermore, the end of the pole 416 is fixedly installed on the top surface of the antenna base 1. There are two sets of poles 416, which are symmetrically distributed around the center line of the top surface of the antenna base 1. Under the constraint of the poles 416, the sleeve 418 can be stably supported and slid.

[0031] Furthermore, the second magnetic ring 414 is slidably disposed inside the outer wall of the slide bar 411, and the second magnetic ring 414 and the first magnetic ring 412 are magnetically attracted to each other. Under the restriction of magnetic attraction, the protective box 415 is stably placed above the antenna body 3.

[0032] Example 2: Based on Example 1, a preferred embodiment of the integrated RFID low-frequency and high-frequency composite antenna structure provided by this utility model is as follows: Figures 1 to 6 As shown: The auxiliary component 43 includes a frame 431 fixedly installed on the outer wall of the antenna mount 1, a first magnetic frame 432 fixedly installed on the inner wall of the frame 431, a second magnetic frame 433 slidably arranged inside the frame 431, and a protective frame 434 fixedly installed on the side wall of the second magnetic frame 433.

[0033] In this embodiment, when the antenna body 3 is in use, the connecting wire harness is plugged into the socket on the outer wall of the antenna base 1. To prevent foreign objects from colliding with the connection between the wire harness and the antenna base 1, protection is required. At this time, the protective frame 434 is pulled, causing the second magnetic frame 433 to slide outward from the frame 431. Under the magnetic attraction between the first magnetic frame 432 and the second magnetic frame 433, the protective frame 434 and the frame 431 stably protect the connection, preventing foreign objects from colliding with the connection and causing signal instability.

[0034] In addition, the first magnetic frame 432 and the second magnetic frame 433 are magnetically attracted to each other, and the outer wall of the protective frame 434 is slidably disposed with respect to the inside of the frame 431. Under the restriction of magnetic attraction, the protective frame 434 and the frame 431 stably protect the connection between the wire harness and the antenna mount 1.

[0035] The above are merely illustrative embodiments of this utility model and are not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to the points of this utility model.
