[0030] The adjustment mechanism 5 includes a slide groove 501 opened on both sides of the beam 1, and a slider 502 is slidably connected inside the slide groove 501. A locking structure 503 is provided on both sides of the slider 502. The inner side of the slider 502 is fixedly connected to an adjustment plate 504. The adjustment plate 504 is located at the top of the beam 1. A rotation structure 505 is provided on the top of the adjustment plate 504. The interior of the front rotation structure 505 is fixedly connected to the passive director 4, and the interior of the rear rotation structure 505 is fixedly connected to the passive reflector 2 and the active vibrator 3 respectively.

[0031] In this embodiment, an adjustment mechanism 5 is provided, and the slide groove 501 and the slider 502 in the adjustment mechanism 5 cooperate to provide a movable foundation for the passive reflector 2, the active vibrator 3 and the passive director 4. The user can slide the slider 502 as needed to adjust the position of each component. After the slider 502 is adjusted to the appropriate position, the locking structure 503 fixes it in the slide groove 501 to prevent the components from moving during use. The adjustment plate 504 is connected to the slider 502 to provide support for the adjustment structure 505. The turning structure 505 can make the passive reflector 2, the active vibrator 3 and the passive director 4 perform steering adjustments to better receive the FM signal. Through the coordinated action of various components, efficient and stable FM signal reception is achieved. When carrying, the turning structure 505 is rotated to make the passive reflector 2, the active vibrator 3 and the passive director 4 present an oblique angle state, and then the sliding block 502 is moved inward, so that the passive reflector 2, the active vibrator 3 and the passive director 4 are close to each other, so as to facilitate carrying and use.

[0032] Specifically, such as Figure 4 As shown, the rotation structure 505 includes a rotating column 5051 torsionally connected to the top of the adjustment plate 504, the interior of the front rotating column 5051 is fixedly connected to the passive director 4, and the interior of the rear rotating column 5051 is fixedly connected to the passive reflector 2 and the active oscillator 3 respectively.

[0034] Specifically, such as Figure 4 As shown, a torsion gear ring 5053 is bolted to the inner side of the ring sleeve 5052 , and the inner side of the torsion gear ring 5053 is in contact with the outer side of the rotating column 5051 .

[0035] In this embodiment: by twisting the rotating column 5051 connected to the top of the adjustment plate 504, the passive director 4 on the front side and the passive reflector 2 and active vibrator 3 on the rear side can be easily adjusted in direction. This design greatly improves the adaptability of the antenna to different signal source directions. The user can quickly and accurately align the antenna with the optimal signal reception direction according to actual conditions, thereby significantly improving the signal reception quality. In addition, the ring sleeves 5052 on both sides of the top of the adjustment plate 504 provide stable support for the rotating column 5051, ensuring that the rotating column 5051 remains stable during rotation without shaking or offsetting. At the same time, the torsion gear ring 5053 bolted to the inside of the ring sleeve 5052 contacts the outside of the rotating column 5051, and can provide a certain resistance after the rotating column 5051 is adjusted to the appropriate angle, preventing the rotating column 5051 from accidentally rotating, thereby ensuring the angular stability of the passive director 4 and the passive reflector 2 and active vibrator 3 on the rear side during use.

[0036] Specifically, such as Figure 5 As shown, the locking structure 503 includes a locking bolt 5031 threadedly connected to the outside of the slider 502 , and the locking bolt 5031 is located on the outside of the beam 1 .

[0037] Specifically, such as Figure 5 As shown, a positioning pad 5032 is bonded to the inner side of the locking bolt 5031 , and the inner side of the positioning pad 5032 is in contact with the outer side of the beam 1 .

[0038] In this embodiment: the locking bolt 5031 connected by the outer thread of the slider 502 can firmly lock the slider 502 in the slide groove 501 of the beam 1 after the slider 502 is adjusted to the appropriate position. This design ensures that the passive director 4, the passive reflector 2 and the active vibrator 3 will not be displaced due to external force or vibration during use, thereby ensuring structural stability and reliability of signal reception. At the same time, the positioning pad 5032 bonded to the inner side of the locking bolt 5031 contacts the outer side of the beam 1, which increases the friction and makes the locking more secure.

[0039] Specifically, such as Figure 6 As shown, a mounting structure 6 is provided in the middle of the beam 1 , and the mounting structure 6 includes a fixing sleeve 601 fixedly connected to the outer side of the beam 1 , and a fixing plate 602 is fixedly connected to the bottom of the fixing sleeve 601 .

[0040] Specifically, such as Figure 6 As shown, a locking ring 603 is provided on the right side of the fixing plate 602 , and an anti-slip pad 604 is bonded to the right side of the fixing plate 602 .

[0041] In this embodiment: by fixing the fixing sleeve 601 fixedly connected to the outside of the beam 1 and the fixing plate 602 at the bottom, a convenient fixing point is provided for the installation of the beam 1. The user can quickly install the beam 1 in a suitable position through the fixing plate 602. At the same time, the locking ring 603 set on the right side of the fixing plate 602 can further enhance the stability of the installation and prevent it from loosening or falling off during subsequent use. At the same time, the anti-slip pad 604 bonded to the right side of the fixing plate 602 increases the friction with the installation surface, improves the firmness of the installation, and ensures that the passive director 4, passive reflector 2 and active vibrator 3 can work stably in various environments during use.

The user can slide the slider 502 as needed to adjust the position of each component. When adjusted to the appropriate position, the locking bolt 5031 threaded on the outside of the slider 502 firmly locks the slider 502 in the slide groove 501 of the beam 1. The positioning pad 5032 bonded to the inside of the locking bolt 5031 contacts the outside of the beam 1, increasing friction and making the locking more secure, ensuring that the passive director 4, the passive reflector 2 and the active vibrator 3 will not be displaced by external force or vibration during use, ensuring the structure Stability and reliability of signal reception. At the same time, the adjustment plate 504 is connected to the slider 502 to provide support for the adjustment structure 505. The rotating column 5051 in the adjustment structure 505 is twisted and connected to the top of the adjustment plate 504. The interior of the front rotating column 5051 is fixedly connected to the passive director 4, and the interior of the rear rotating column 5051 is fixedly connected to the passive reflector 2 and the active vibrator 3 respectively. The user can rotate the rotating column 5051 according to actual conditions to easily adjust the passive director 4 on the front side and the passive reflector 2 and the active vibrator 3 on the rear side, thereby greatly improving the adaptability of the antenna to different signal source directions, quickly and accurately aligning the antenna with the best signal reception direction, and significantly improving the signal reception quality. The ring sleeves 5052 on both sides of the top of the adjustment plate 504 provide stable support for the rotating column 5051, ensuring that the rotating column 5051 remains stable during rotation without shaking or offsetting. The torsion gear ring 5053 bolted to the inner side of the ring sleeve 5052 contacts the outer side of the rotating column 5051, and provides a certain resistance after the rotating column 5051 is adjusted to a suitable angle, preventing the rotating column 5051 from rotating accidentally, thereby ensuring the angular stability of the passive director 4 and the passive reflector 2 and active vibrator 3 on the rear side during use. In addition, the mounting structure 6 in the middle of the beam 1 includes a fixing sleeve 601 fixedly connected to the outer side of the beam 1 and a fixing plate 602 at the bottom, which provides a convenient fixing point for the installation of the beam 1, and the user can The beam 1 is quickly installed in the appropriate position through the fixing plate 602. The locking ring 603 set on the right side of the fixing plate 602 can further enhance the stability of the installation and prevent it from loosening or falling off during subsequent use. The anti-slip pad 604 bonded to the right side of the fixing plate 602 increases the friction with the installation surface, improves the firmness of the installation, and ensures that the passive director 4, passive reflector 2 and active vibrator 3 can work stably in various environments. When carrying, the rotation structure 505 is rotated to make the passive reflector 2, active vibrator 3 and passive director 4 in an oblique state, and then the sliding slider 502 is moved inward to make the passive reflector 2, active vibrator 3 and passive director 4 close to each other for easy carrying and use.
