[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0026] like Figure 1-8As shown in the figure, an antenna installed using the gaps in a metal frame is provided in this embodiment of the present invention. It includes a metal frame 1, a PCB board 2 is installed inside the metal frame 1, and two gaps 3 are left between the PCB board 2 and the inner side of the metal frame 1. Both gaps 3 are gap antennas, and the two ends of the two gap antennas are divided into ANT4. Two antenna feed points 5 and two return points 6 are provided in each of the two gaps 3. Multiple slots 7 are opened at the two ends of the PCB board 2. Openings 8 connected to the slots 7 are opened at the two ends of the metal frame 1. A snap-fit assembly is installed in each of the two openings 8. The snap-fit assembly includes multiple snap blocks 9 that slide in the openings 8 and correspond to the snap blocks 7, a toothed plate 10 installed at one end of the multiple snap blocks 9, a rotating rod 11 that rotates in the openings 8, and multiple teeth 12 installed around the rotating rod 11 and meshing with the multiple toothed plates 10.
[0027] In this embodiment, a metal frame 1 is included; Specifically, rectangular slots 16 are provided at the four opposite corners of the lower side of the metal frame 1. The inner side of each of the four rectangular slots 16 is elastically and slidably fitted with a mounting plate 17, and multiple teeth 12 surround the periphery of the rotating rod 11. Through the rectangular slots 16, the mounting plate 17 can be retracted into the rectangular slots 16, thereby reducing unnecessary space occupation. At the same time, it can also be moved out of the rectangular slots 16 to prepare for the next step of bolt fixing. Specifically, mounting holes 18 are provided in the center of each of the four mounting plates 17, and limiting grooves 19 are provided on the inner sides of each of the four rectangular grooves 16. Specifically, each of the multiple limiting grooves 19 is equipped with a support rod 20, and each of the four mounting plates 17 is equipped with a limiting block 21 on one side of each other. Through the setting of the limiting block 21, the mounting plate 17 can only move horizontally along the periphery of the support rod 20, thereby guiding the mounting plate 17. Specifically, each of the multiple limiting blocks 21 has a slot in the middle, the support rod 20 is located in the slot and slides with it, and the limiting block 21 is elastic and slides with it in the limiting groove 19. Specifically, springs 22 are installed between the inner side of the multiple limiting grooves 19 and one end of the multiple limiting blocks 21. The springs 22 are sleeved on the periphery of the support rod 20. Through the springs 22, the mounting plate 17 can be elastically extended and retracted and automatically returned to its original position, so that it retracts into the rectangular groove 16, thereby avoiding occupying extra space.
[0028] In this embodiment, a PCB board 2 is installed inside the metal frame 1. Two gaps 3 are left between the PCB board 2 and the inner side of the metal frame 1. Both gaps 3 are slot antennas. The two ends of the two slot antennas are divided into ANT4. Two antenna feed points 5 and two return points 6 are provided in each of the two gaps 3. Multiple slots 7 are opened at the two ends of the PCB board 2. Openings 8 connected to the slots 7 are opened at the two ends of the metal frame 1. Specifically, the width of the two gaps 3 is 1mm, the frequency of the four ANT4 is 4.4GHz-5GHz, and the size of the metal frame 1 is 150mm. 76mm 5mm.
[0029] In this embodiment, both openings 8 are equipped with snap-fit components. The snap-fit components include multiple snap blocks 9 that are slidably fitted in the openings 8 and correspond to the snap slots 7, toothed plates 10 installed at one end of the multiple snap blocks 9, rotating rods 11 that are rotatably fitted in the openings 8, and multiple teeth 12 installed around the rotating rods 11 and meshing with the multiple toothed plates 10. Specifically, the snap-fit assembly also includes multiple sliding grooves 13 opened at the top of the opening 8, sliders 14 respectively installed on the upper ends of multiple toothed plates 10, and a turntable 15 installed at one end of the rotating rod 11. The sliders 14 are slidably engaged in the sliding grooves 13. Through the sliders 14, the toothed plates 10 can only move horizontally in the opening 8, thereby guiding the snap-fit block 9.
[0030] Working steps: 1. When PCB board 2 needs to be installed, first place PCB board 2 inside the metal frame 1, then rotate the two turntables 15, which can drive the two rotating rods 11 to rotate, and drive multiple teeth 12 to rotate synchronously, so that multiple teeth 12 mesh with multiple toothed plates 10 and rotate, thereby driving multiple toothed plates 10 and multiple locking blocks 9 to move horizontally synchronously, so that multiple locking blocks 9 extend into multiple locking slots 7 and make a locking relationship with them, thereby fixing PCB board 2 to the metal frame 1. At this time, multiple sliders 14 slide in multiple sliding grooves 13 to realize the installation of PCB board 2. When PCB board 2 needs to be disassembled, the operation is reversed. 2. After the PCB board 2 is installed, the two gaps 3 left between the PCB board 2 and the metal frame 1 on the opposite inner side can form two closed gap antennas, thereby generating the resonance of four ANT4. Changing the position of the return point 6 can shift the resonance to the left and right. At the same time, changing the position of the four antenna feed points 5 can change the bandwidth and also shift the resonance to the left and right. In addition, each side has a return point 6 with a width of 1mm to form a closed gap and isolate the interference between the four ANT4. 3. When the metal frame 1 needs to be installed, manually push the four mounting plates 17. At this time, the multiple limiting blocks 21 elastically and slidingly engage with the multiple limiting grooves 19. Simultaneously, the multiple limiting blocks 21 move horizontally along the periphery of the multiple support rods 20, and the multiple springs 22 elastically extend and retract at the same time. This allows the four mounting plates 17 to extend out of the rectangular grooves 16. Then, the bolts are inserted into the four mounting holes 18, thereby installing the metal frame 1 in the designated position. When the four mounting plates 17 are no longer needed for fixing, the multiple springs 22 drive the four mounting plates 17 to elastically extend and retract and automatically return to their original positions, causing the four mounting plates 17 to retract into the four rectangular grooves 16, thereby reducing unnecessary space occupation.
[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
