[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs.

[0021] The utility model embodiment provides a 4G module with a protection structure, combined with Figures 1 to 4 As shown, it includes a module body 1 and a mounting base plate 2 installed at the lower end of the module body 1, a protection structure 3 for protecting the module body 1 is arranged on the mounting base plate 2, and the module body 1 is located inside the protection structure 3, and the module body 1 is in contact with the protection structure 3, the module body 1 is fixedly connected to the mounting base plate 2, and the mounting base plate 2 is installed on the PCB board, a circular hole 4 is opened on the mounting base plate 2, and the circular hole 4 is located at the corner position of the mounting base plate 2, the lower end of the protection structure 3 is inserted into the circular hole 4 on the mounting base plate 2, and the protection structure 3 is fixed to the PCB board by screws.

[0022] Specifically, a circular hole 4 is opened on the installation base plate 2. When the entire 4G module and the protective structure 3 are installed, the supporting part in the protective structure 3 is aligned with the circular hole 4, and the screws pass through the supporting part and the circular hole 4 in the protective structure 3. The screws can be used to simultaneously fix the protective structure 3 and the installation base plate 2. There is no need to install the protective structure 3 on the installation base plate 2 separately, and the installation is convenient and quick.

[0023] During the installation process, the mounting base plate 2 with the module body 1 is set on the PCB board, and the protective structure 3 is placed on the mounting base plate 2, ensuring that the holes on the protective structure 3 are aligned with the circular holes 4 on the mounting base plate 2 and the holes on the PCB board, and the screws pass through the protective structure 3 and the mounting base plate 2 to connect to the PCB board, thereby completing the installation of the entire 4G module. During use, the protective structure 3 protects the module body 1 and can also dissipate heat, thereby improving the heat dissipation effect of the module body 1.

[0024] Through the above embodiment, the protection structure 3 includes a protection cover 301, a fixing column 302, a heat sink 305 and a connecting plate 306, the protection cover 301 is fixedly connected to the fixing column 302, and the lower end of the fixing column 302 is plugged into the circular hole 4, the protection cover 301 is provided with a strip hole, the heat sink 305 is fixedly connected to the connecting plate 306, and the heat sink 305 passes through the strip hole on the protection cover 301, and the lower end of the heat sink 305 contacts the module body 1, the protection structure 3 also includes a fixing rod 303, a limiting plate 304, a plug-in column 307, a tightening spring 308, a fixing plate 309 abutting plate 310 and a stabilizing spring 311, the fixing rod 303 It is fixedly connected to the limit plate 304, and the fixing rod 303 is installed on the protective cover 301, the limit plate 304 is provided with a through hole, the plug-in column 307 is fixed on the connecting plate 306, and the plug-in column 307 passes through the through hole on the limit plate 304, the clamping spring 308 is sleeved on the plug-in column 307, and the ends of the clamping spring 308 respectively contact the limit plate 304 and the connecting plate 306, the fixing plate 309 is fixedly installed on the fixing column 302, the abutting plate 310 and the stabilizing spring 311 are fixedly connected, and the abutting plate 310 and the stabilizing spring 311 are sleeved on the fixing column 302, and the upper end of the stabilizing spring 311 is fixedly connected to the fixing plate 309.

[0025] When installing the 4G module, after the installation base plate 2 is placed, the protective cover 301 is set above the installation base plate 2, and the fixing column 302 is inserted into the circular hole 4. At this time, the abutment plate 310 at the lower end of the stabilizing spring 311 below the fixing plate 309 contacts the installation base plate 2, and at the same time, the lower end of the heat sink 305 in the strip hole on the protective cover 301 contacts the module body 1. After the screws are passed through the fixing column 302 and connected to the PCB board, the protective structure 3 is fixedly installed with the installation base plate 2. At this time, the stabilizing spring 311 is in a compressed state, so that the abutment plate 310 exerts a certain force on the installation base plate 2, ensuring that the installation base plate 2 has good stability during subsequent use, and can effectively prevent loosening. In addition, during the installation process, as the protective cover 301 descends, the module body 1 has a limiting force on the heat sink 305. The blocking effect causes the heat sink 305 to rise with the connecting plate 306 relative to the protective cover 301, and the fixing rod 303 descends with the limiting plate 304 as the protective cover 301 does. The distance between the limiting plate 304 and the connecting plate 306 becomes smaller, and the abutting spring 308 is compressed. The abutting spring 308 ensures that the heat sink 305 is in close contact with the module body 1 while rising and falling relative to the protective cover 301, thereby ensuring the subsequent heat dissipation effect. After the 4G module is installed and put into use, the protective cover 301 protects the module body 1, and the heat sink 305 conducts and dissipates the heat generated by the module body 1, thereby improving the heat dissipation effect of the 4G module and ensuring the effective use of the module. The stabilizing spring 311 at the lower end of the fixing plate 309 enables the abutting plate 310 to stabilize the mounting base plate 2, and has an excellent anti-loosening effect.

[0026] Specifically, by setting up the protective structure 3, the protective cover 301 can be used to effectively protect the module body 1 to prevent the module body 1 from being damaged by impact. A fixing plate 309, an abutment plate 310 and a stabilizing spring 311 are set on the fixing column 302. After the module body 1, the mounting base plate 2 and the protective structure 3 are installed by screws, under the action of the stabilizing spring 311, the abutment plate 310 applies a force to the mounting base plate 2 at the lower end of the module body 1, which can prevent loosening. A heat sink 305 is set on the protective cover 301, which is used in conjunction with structures such as the connecting plate 306, the plug-in column 307, and the tightening spring 308. It can not only effectively dissipate heat, but also ensure that the heat sink 305 is in close contact with the module body 1, thereby ensuring the heat dissipation conduction effect.
