Description

Technical Field

[0001] This utility model relates to the field of radio frequency antenna technology, and in particular to an anti-interference radio frequency antenna. Background Technology

[0002] As a key component in the front-end of signal transmission and reception, the performance of radio frequency (RF) antennas directly determines the quality and reliability of communication systems. However, with the increasing density of electronic devices and the growing complexity of the electromagnetic environment, RF antennas are highly susceptible to electromagnetic interference from external sources or other devices during operation, leading to signal distortion, decreased sensitivity, and even communication interruption. To address this issue, common practices include adding metal shielding to the antenna or employing special filtering circuits. However, these traditional methods often suffer from drawbacks such as bulky structures, inconvenient installation and disassembly, and low integration with the antenna body. Especially in applications requiring frequent maintenance or replacement of antenna components, the complex fixing and protection structures actually increase operational difficulty and maintenance costs.

[0003] In existing technologies, mechanical structures used to fix and protect antenna elements typically employ bolt fastening or direct locking with clips. While these structures provide a certain degree of fixation, under long-term vibration or impact conditions, bolts may loosen, and clips are prone to fatigue failure, leading to displacement of the antenna body or detachment of the protective cover, thus affecting the antenna's electrical performance and protective effectiveness.

[0004] Therefore, this application provides an anti-interference radio frequency antenna. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an anti-interference radio frequency antenna. This invention achieves convenient installation and stable anti-loosening of the radio frequency body through a mechanical interlocking structure, and integrates a protective cover and an anti-interference layer, effectively improving the structural reliability and signal anti-interference performance in complex environments.

[0006] This utility model is achieved through the following technical solution: This utility model discloses an anti-interference radio frequency antenna, characterized in that it includes: a substrate;

[0007] The main body of the radio frequency antenna is arranged in an array on the substrate;

[0008] The mounting mechanism is fixed on the substrate and surrounds the radio frequency antenna body for fixing the radio frequency antenna body;

[0009] An anti-interference component is detachably mounted on the mounting mechanism and covers the outside of the radio frequency antenna body.

[0010] Preferably, the mounting mechanism includes an annular fixing base, on which an annular groove and multiple communicating grooves are formed. The communicating grooves are evenly distributed along the circumference of the annular fixing base and communicate with the inner side of the annular fixing base. A limiting block is slidably disposed in each communicating groove. The edge of the radio frequency antenna body is provided with a limiting groove that matches the limiting block. When the anti-interference component is inserted into the annular groove, its inner wall can abut against the limiting block, so that the limiting block remains in the state of extending into the limiting groove.

[0011] Preferably, an L-shaped fixing plate is also fixed in the communicating groove, and a fixing rod is connected to the limiting block. The fixing rod passes through the through hole in the L-shaped fixing plate and is connected to an abutment plate. A second return spring is sleeved on the fixing rod. The two ends of the second return spring abut against the L-shaped fixing plate and the limiting block or the abutment plate, respectively, to provide the limiting block with an elastic force to extend into the limiting groove.

[0012] Preferably, the anti-interference component includes an anti-interference protective cover, the bottom of which is provided with an annular suction cup, and the anti-interference protective cover is adsorbed to the bottom of the annular groove by the annular suction cup.

[0013] Preferably, an anti-interference layer is fixed on the inner wall of the anti-interference protective cover.

[0014] Preferably, the inner wall of the anti-interference protective cover is provided with multiple locking units at equal intervals along its circumference;

[0015] Each of the locking units includes a sleeve fixed on the anti-interference protective cover. A sleeve rod is slidably disposed inside the sleeve by a return spring. One end of the sleeve rod extends to the outside of the sleeve and is connected to an L-shaped limiting block. The other end is connected to a connecting rod extending to the outside of the anti-interference protective cover.

[0016] After the anti-interference protective cover is inserted into the annular groove, under the action of the first reset spring, the L-shaped limiting block can hook onto the L-shaped fixing plate in the communicating groove.

[0017] Preferably, the two sides of the substrate are fixed with fasteners having fixing holes.

[0018] This utility model has the following advantages:

[0019] (1) This utility model achieves rapid and reliable installation and locking of the RF antenna body by cleverly combining the installation mechanism with the anti-interference component. After the RF antenna body is placed, the spring-driven limiting block in the installation mechanism can automatically lock into its limiting groove to complete the initial positioning; then, when the anti-interference component is inserted into the annular groove as a whole, its inner wall will abut against the other end of the limiting mechanism, firmly locking the limiting block in the groove, forming a double insurance. This mechanism not only ensures the stability of the antenna body in the vibration environment and prevents accidental loosening, but also eliminates the need for complicated tools in the entire assembly process, simplifying the installation and subsequent maintenance and replacement procedures and improving the ease of use.

[0020] (2) While providing excellent anti-interference performance, this utility model also takes into account the stability of the structure itself and overall protection. The anti-interference component itself forms a reliable hook and fixation with the annular groove and L-shaped fixing plate of the installation mechanism through the annular suction cup at its bottom and the L-shaped limiting block mechanism with spring on the inner side, ensuring that the protective cover itself is firmly installed.

These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific operation processes. However, the protection scope of this utility model is not limited to the following embodiments. In the description of this utility model, words such as "front," "rear," "left," and "right," which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] Example 1

[0028] Example 1 discloses an anti-interference radio frequency antenna, such as Figures 1-4 As shown, the device includes a substrate 100 and radio frequency antenna bodies 400 evenly spaced on the substrate 100. Each radio frequency antenna body 400 is equipped with an anti-interference component 200 for protection. Mounting mechanisms 300 for limiting the position of the radio frequency antenna bodies 400 and the anti-interference components 200 are fixed on the substrate 100 outside the radio frequency antenna bodies 400. The mounting mechanism 300 includes an annular fixing base 301 and an annular groove 302 formed in the annular fixing base 301. The annular groove 302 allows the anti-interference component 200 to be inserted into it. The annular groove 302 is evenly spaced along the circumference of the annular fixing base 301, allowing the annular groove 302 to engage with the annular fixing base 301. The inner side of the communicating groove 306 is connected, and the limiting block 304 is slidably arranged inside the communicating groove 306. The limiting groove 401 is opened at the edge of the radio frequency antenna body 400. The limiting block 304 is inserted into the limiting groove 401 to limit the radio frequency antenna body 400. When limiting the radio frequency antenna body 400, the radio frequency antenna body 400 is installed on the inner side of the annular fixing seat 301, and then the limiting block 304 and the limiting groove 401 correspond to each other to limit the radio frequency antenna body 400. Then, the anti-interference component 200 is inserted into the interior of the annular groove 302, and the inner wall of the anti-interference component 200 abuts against the limiting block 304 to prevent the limiting block 304 from disengaging from the limiting groove 401.

[0029] Furthermore, such as Figure 2 , Figure 3 and Figure 4As shown, in this embodiment, an L-shaped fixing plate 303 is also fixed inside the connecting groove 306, and a through hole is opened in the middle of the L-shaped fixing plate 303. A fixing rod 307 is connected to one side of the limiting block 304, and the fixing rod 307 passes through the through hole and is connected to an abutment plate 308. A second return spring 305 is sleeved on the fixing rod 307 on the left side of the L-shaped fixing plate 303. It is worth noting that the height of the limiting block 304 is higher than the height of the annular fixing seat 301, so that when the limiting block 304 limits the radio frequency antenna body 400, the elastic force of the second return spring 305 will move the limiting block 304 into the limiting groove 401. Inside, the radio frequency antenna body 400 is limited. When the limiting block 304 releases its limiting effect on the radio frequency antenna body 400, the limiting block 304 can be manually pushed to release its effect on the radio frequency antenna body 400, thereby allowing the radio frequency antenna body 400 to be replaced. During this process, one side of the L-shaped fixing plate 303 is not flush with the side wall of the L-shaped fixing plate 303, but a space is reserved to accommodate the contact plate 308. This allows the inner wall of the anti-interference component 200 to contact the contact plate 308 when the anti-interference component 200 is inserted into the annular groove 302, thereby preventing the limiting block 304 from disengaging from the limiting groove 401.

[0030] like Figure 1 and Figure 2 As shown, in this embodiment, a fixing member 101 is fixedly connected to the edge positions on both sides of the substrate 100, and a fixing hole is formed on the fixing member 101.

[0031] like Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, the anti-interference component 200 includes an anti-interference protective cover 206. By inserting the anti-interference protective cover 206 into the interior of the annular groove 302 and providing an annular suction cup 201 at the bottom end of the anti-interference protective cover 206, the anti-interference protective cover 206 is inserted into the annular groove 302 and then adsorbed to the bottom end of the interior of the annular groove 302 by the annular suction cup 201.

[0032] Furthermore, in this embodiment, an anti-interference layer is fixedly provided on the inner side of the anti-interference protective cover 206. The anti-interference protective cover and the anti-interference layer are combined to improve the anti-interference performance of the radio frequency antenna body.

[0033] like Figure 2 , Figure 3 and Figure 4As shown, in this embodiment, sleeves 204 are fixedly provided at equal intervals along the circumference of the inner side of the anti-interference protective cover 206, and the anti-interference protective cover 206 has a through opening at the position of the sleeve 204. A sleeve rod is slidably provided in the sleeve 204 by a return spring 203. One end of the sleeve rod extends to the outside of the sleeve 204 and is connected to an L-shaped limiting block 205. The other end of the sleeve rod is connected to a connecting rod 202, and the connecting rod 202 extends through the through hole to the outside of the anti-interference protective cover 206. When the anti-interference protective cover 206 is inserted into the annular groove 302, the L-shaped limiting block 205 must first be aligned with the connecting groove 306. Then, by pushing the connecting rod 202, the L-shaped limiting block 205 can enter from the top gap of the connecting groove 306 and be reset under the action of the return spring 203, so that the L-shaped fixing plate 303 and the L-shaped limiting block 205 are hooked together, thereby limiting and fixing the anti-interference protective cover 206.

[0034] In this embodiment, to ensure stable operation of the antenna bodies and resist external signal interference, each antenna body is equipped with a specially designed anti-interference component 200 for protection. Installation and positioning are accomplished using a mounting mechanism 300 mounted on the substrate 100. The core of this mechanism is an annular fixing seat 301 with an annular groove 302. Circumferentially, the annular fixing seat 301 has evenly spaced connecting grooves 306 that connect the inner and outer sides of the annular groove. Each connecting groove contains a sliding limiting mechanism with elastic reset force provided by a second reset spring 305, and its end limiting block 304 can extend outwards. When the RF antenna body 400 is placed in the center of the annular fixing seat 301, its edge limiting groove 401 aligns with the limiting block 304. Under the push of the second reset spring 305, the limiting block 304 automatically slides into the limiting groove, thus initially fixing the antenna body. Subsequently, the anti-interference component 200 needs to be inserted into the annular groove 302 as a whole. Its inner sidewall will just abut against the abutment plate 308 on the other side of the limiting mechanism, firmly "locking" the limiting block 304 in the limiting groove 401 to prevent it from accidentally coming out due to vibration or other reasons, thus achieving the final reliable limiting of the antenna body.

[0035] After the anti-interference protective cover 206 is inserted into the annular groove 302, the annular suction cup 201 at its bottom provides initial adsorption and fixation. More importantly, a locking mechanism with springs is evenly arranged along the circumference of its inner wall: the sleeve 204 contains a sleeve rod held by a return spring 203, and one end of the sleeve rod is connected to an L-shaped limiting block 205 that can extend outward from the protective cover. When inserting the protective cover into the annular groove, the L-shaped limiting block 205 needs to be aligned with the connecting groove 306 first, and the connecting rod 202 needs to be manually pressed inward to compress the return spring 203, so that the L-shaped limiting block 205 can enter the inner side of the annular groove through the gap above the connecting groove. Then the connecting rod is released, and under the action of the reset spring 203, the sleeve rod drives the L-shaped limiting block 205 to reset, so that its end just hooks onto the L-shaped fixing plate 303 fixed in the connecting groove, thereby firmly locking the entire anti-interference protective cover 206 onto the mounting mechanism 300. Through this dual locking design, the anti-interference component locks the limiting block of the mounting mechanism, while the mounting mechanism locks the main body of the radio frequency antenna, making the entire antenna unit structure stable, easy to disassemble and have good protection performance.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
