[0002] With the growth of communication demand, mobile signals need to be enhanced in blind spots and weak areas that are difficult to cover by communication networks. Currently, the commonly used signal enhancement devices are mostly signal amplifiers, also called repeaters. Repeaters are used as one of the necessary means to achieve the goal of "small capacity, large coverage". The main reason is that the use of repeaters can ensure network coverage without increasing the number of base stations, and secondly, its cost is much lower than that of micro-cellular systems with the same effect. Repeaters are a preferred solution to solve the problem of extending the coverage of communication networks. Compared with base stations, they have the advantages of simple structure, less investment and easy installation. They can be widely used in blind spots and weak areas that are difficult to cover, such as shopping malls, hotels, airports, docks, stations, gymnasiums, entertainment halls, subways, tunnels, highways, islands and other places to improve communication quality, solve the problem of dropped calls, and optimize wireless communication networks.

[0041] The bracket 1 includes a main shaft 6, a mounting seat 7 is provided on the top of the main shaft 6, and the mounting seat 7 is fixedly mounted on the top wall of the bracket cavity 18. A sleeve 2 is slidably connected to the main shaft 6, a locking screw 8 is threadedly connected to the sleeve 2, and a group of telescopic rods 3 are rotatably connected to the circumferential outer wall of the sleeve 2. The telescopic rod 3 is a triangular support frame structure, and the three support frames are all telescopic structures. The central pull rod 5 of the middle sleeve of the three support frames can adjust and control the opening degree of the three support frames. When the three support frames are closed, the central pull rod 5 is also retracted and closed. The surface of the locking screw 8 is provided with anti-slip grooves, which is convenient for the user to hold the head of the locking screw 8 and twist it. After the locking screw 8 is locked, the sleeve 2 and the main shaft 6 can be fixed to prevent the sleeve from slipping on the main shaft 6.

[0042] The mounting seat 7 is connected to the top wall of the bracket cavity 18 through a detachable connector, and corresponding positions of the mounting seat 7 and the bracket cavity 18 are provided with connecting holes, and bolts, screws and other connectors are inserted into the corresponding connecting holes of the mounting seat 7 and the bracket cavity 18 to achieve the connection between the mounting seat 7 and the bracket cavity 18, thereby fixing the bracket 1 in the bracket cavity 18. When the bracket 1 is damaged or fails, the mounting seat 7 can be removed from the bracket cavity 18 and replaced with a new bracket 1, or the bracket 1 can be disassembled and repaired and then installed back into the bracket cavity 18.

[0043] Working principle of this embodiment:

[0044] This embodiment is used in pairs, with the repeater 21 in one box 9 serving as a remote machine and the repeater 21 in the other box 9 serving as a near-end machine. The plate antenna 12 on one side of the box 9 serves as a forward antenna for receiving mobile signals, and the remote machine amplifies the useful signal, suppresses the noise signal in the signal, and improves the signal-to-noise ratio S / N; then it is down-converted to an intermediate frequency signal, filtered by a filter, amplified by the intermediate frequency, and then up-converted to a radio frequency by frequency shifting, amplified by a power amplifier, and transmitted to the rear machine by the plate antenna 12 on the other side of the box 9 as a backward antenna retransmission antenna to transmit to the mobile station; at the same time, the backward antenna receives the uplink signal of the mobile station, and is processed by the uplink amplification link along the opposite path: that is, it is transmitted to the base station through a low noise amplifier, a down converter, a filter, an intermediate amplifier, an up converter, and a power amplifier. Thus, two-way communication between the base station and the mobile station is achieved.

[0045] In this embodiment, the battery 20 is used as a mobile power source to power the plate antenna 12 and the repeater 21, and can be used without plugging in. The touch screen 22 is used to control the device power on and off, and to adjust related parameters. The bracket 1 in the bracket cavity 18 provides support for the device after being unfolded. When unfolding, the sleeve 2 is first pulled out of the bracket cavity 18, and then the sleeve 2 is locked by the locking screw 8. After the locking is completed, the telescopic rod 3 is extended, and the telescopic length of the telescopic rod 3 is selected according to actual needs. This embodiment has a simple structure and is portable, and can be used for signal enhancement outdoors or other temporary occasions.

[0046] Example 2: Please refer to Figure 7 , a mobile signal enhancement device, which differs from Example 1 in that a hinge seat 13 is fixedly connected to the top of the antenna cavity 11, a plate antenna 12 is hinged on the hinge seat 13, and an antenna deployment electric push rod 14 is hinged between the bottom of the antenna cavity 11 and the lower end of the plate antenna 12.

[0047] In this embodiment, the antenna deployment electric push rod 14 is used to control the deployment and folding of the plate antenna 12 .

[0048] The two ends of the antenna deployment electric push rod 14 are respectively hinged at the bottom of the antenna cavity 11 and the lower end of the plate antenna 12. When the antenna deployment electric push rod 14 pushes the plate antenna 12 to move outward, the antenna deployment electric push rod 14 will rotate with the bottom of the antenna cavity 11 and the lower end of the plate antenna 12. As the antenna deployment electric push rod 14 extends, the lower end of the plate antenna is rotated and pushed outward around the hinge seat until it opens to a suitable position. When it is necessary to retract the plate antenna 12, the antenna deployment electric push rod 14 retracts, the hinge seat returns to its original position, and the plate antenna is retracted to its original position. As a portable mobile signal enhancement device, the recovery characteristics of the plate antenna 12 make it easy to store, move and use.

[0049] Example 3: Please refer to Figure 1 , a mobile signal enhancement device, which differs from Example 1 in that a solar photovoltaic panel 17 is hinged on the top of the left and right side walls of the box body 9, and the solar photovoltaic panel 17 is equipped with an inverter. The solar photovoltaic panel 17 charges the battery 20, and side mounting cavities 15 are provided on the left and right sides of the bracket cavity 18, and a photovoltaic panel unfolding electric push rod 16 is hinged between the side mounting cavity 15 and the lower end of the solar photovoltaic panel 17.

[0050] In this embodiment, the solar photovoltaic panel 17 charges the battery 20 to increase the battery life of the device, and the photovoltaic panel deployment electric push rod 16 controls the deployment of the solar photovoltaic panel 17 .

[0051] The two ends of the solar photovoltaic panel 17 are respectively hinged to the box body 9 and the lower end of the solar photovoltaic panel 17. In the process of the photovoltaic panel deployment electric push rod 16 pushing the solar photovoltaic panel 17 outward, the photovoltaic panel deployment electric push rod 16 will rotate with the box body 9 and the lower end of the solar photovoltaic panel 17. As the photovoltaic panel deployment electric push rod 16 extends, the upper end of the solar photovoltaic panel 17 is rotated and pushed outward around the connection with the box body until it opens to a suitable position. When the solar photovoltaic panel 17 needs to be retracted, the photovoltaic panel deployment electric push rod 16 retracts to retract the plate antenna to its initial state. As a convenient mobile signal enhancement device, the solar photovoltaic panel 17 is deployed outward when in use to obtain a larger irradiation area, and is easy to store and move after retraction.

[0052] Example 4: Please refer to Figure 8 , a mobile signal enhancement device, which differs from Example 1 in that a locking buckle 4 is provided at the end of each section of the telescopic rod 3.

[0053] In this embodiment, the locking buckle 4 is used to lock a single section of the telescopic rod 3. The telescopic rod is a multi-section telescopic structure, and the telescopic length of the telescopic rod can be adjusted according to the use requirements, and the adjusted telescopic rod is locked and fixed. The locking buckle 4 adopts an existing locking buckle structure, which can be a spiral locking buckle structure or a clamp locking buckle structure.

[0054] Example 5: Please refer to Figure 8 , a mobile signal enhancement device, which is different from Example 1 in that a rod sleeve is sleeved at the lower end of a main shaft 6, and a center pull rod 5 is hinged between the end of the uppermost section of a telescopic rod 3 and the rod sleeve.

[0055] In this embodiment, the central pull rod 5 is used to control the expansion angle of the telescopic rod 3. When the central pull rod 5 is pulled upward, the expansion angle of the telescopic rod is larger, and when the central pull rod is pulled downward, the expansion angle of the telescopic rod is smaller. The central pull rod can limit the expansion of each telescopic rod 3 to achieve a stable triangular support.

[0056] Example 6: Please refer to Figure 1 , a mobile signal enhancement device, which is different from Example 1 in that a handle 10 is provided on the top of the box body 9.

[0057] In this embodiment, the handle 10 is convenient for carrying the case 9. The handle 10 can be integrally formed with the case 9, or fixed to the upper end surface of the case 9 by welding. The case 9 can be integrally formed of lightweight plastic, which helps to reduce the weight of the mobile signal enhancement device and facilitates the user to move.

[0058] Example 7: Please refer to Figures 5 to 7 , a mobile signal enhancement device, which is different from Example 1 in that the box body 9 is set as a closed box structure, and the bottom of the box body 9 is provided with heat dissipation holes, which are connected to the bracket cavity 18.

[0059] In this embodiment, the box body 9 is set as a closed box structure with good waterproof performance, and the heat dissipation holes are used to ensure the heat dissipation performance of the device. The heat dissipation holes at the bottom can prevent rain from entering the box body 9 and causing damage to various components, and ensure that the heat of each working component during the working process can be dissipated outward through the heat dissipation holes, thereby avoiding overheating damage to the working components and improving the service life of the mobile signal enhancement device.

[0060] Example 8: Please refer to Figure 8 , a mobile signal enhancement device, which is different from Example 1 in that a ground nail hole is provided at the end of the lowermost section of the telescopic rod 3, and the ground nail hole is used to penetrate the ground nail.

[0061] In this embodiment, the ground nail hole is used to insert the ground nail, which can improve the stability of the bracket 1. After the mobile signal enhancement device is placed at the designated location, the ground nail is inserted into the ground nail hole, and the ground nail hole is inserted into the ground, thereby completing the fixation of the mobile signal enhancement device to prevent pedestrians from knocking over the mobile signal enhancement device or strong winds from overturning the mobile signal enhancement device.

[0062] Example 9: Please refer to Figure 8, a mobile signal enhancement device, which differs from Example 1 in that a hook is provided at the lower end of the main shaft 6, and the hook is used to hang a counterweight.

[0063] In this embodiment, the hook is convenient for hanging a counterweight, thereby further improving the stability of the bracket 1.

[0064] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application.
