[0019] In order to further understand the content, features and effects of the present invention, the following embodiments are cited and described in detail in conjunction with the accompanying drawings.

[0020] The structure of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] As Figures 1 to 12 shown, a kind of anti-shake vehicle-mounted router provided by an embodiment of the present invention includes a housing 1. A processor and a wireless communication module are arranged inside the housing 1. A plurality of interfaces 13 are arranged at one end of the housing 1. An antenna 12 is arranged at the other end of the housing 1. Heat dissipation holes 11 are arranged on both sides of the housing 1. A mounting block 15 is fixedly connected to the bottom of the housing 1. The mounting block 15 is inserted into the anti-shake base 2. A mounting plate 4 is fixedly connected to the bottom of the anti-shake base 2. Connection blocks 14 are fixedly connected to the four corners of the lower surface of the housing 1.

[0022] Furthermore, the anti-shake base 2 includes a baffle 21, a limit seat 22 and a movable seat 24. The limit seat 22 is fixedly connected to one side of the baffle 21. The movable seat 24 is inserted into the limit seat 22. A slot 2101 is formed in the baffle 21. One end of the movable seat 24 is fixedly connected with a plug 2401, and the plug 2401 is correspondingly inserted into the slot 2101. An installation groove 2201 is formed at the top of the limit seat 22, and the installation block 15 is inserted into the installation groove 2201. A threaded rod 23 is fixedly connected to one side of the limit seat 22. A clamping block 2301 is movably connected to the threaded rod 23 through an elastic piece 2302. Rack bars 27 are fixedly connected to both side walls at the opening of the movable seat 24. A first gear 26 is meshed and connected in the middle of the two rack bars 27. The first gear 26 is rotatably connected to a fixed block 25, and the fixed block 25 is fixedly connected to the side wall of the movable seat 24. The first gear 26 is threadedly sleeved on the threaded rod 23, and the clamping block 2301 is clamped to one side of the first gear 26.

[0023] Specifically, the housing 1 is detachably installed on the limit seat 22 and the movable seat 24 through the installation block 15. During use, the installation block 15 is placed in the installation groove 2201, the movable seat 24 is correspondingly inserted into the limit seat 22, and the movable seat 24 is moved towards the direction close to the baffle 21. The movable seat 24 pushes the installation block 15 to move, so that one end of the installation block 15 abuts against the side wall of the installation groove 2201. At the same time, the plug 2401 is correspondingly inserted into the slot 2101, and the first gear 26 is sleeved on the threaded rod 23. Through the threaded cooperation between the first gear 26 and the threaded rod 23, the first gear 26 rotates during the process of following the fixed block 25 and the movable seat 24. The two rack bars 27 are meshed and connected with the first gear 26. When the first gear 26 rotates, the two rack bars 27 move relatively, so that the inner side walls of the movable seat 24 are tightly attached to the limit seat 22, making the connection between the movable seat 24 and the limit seat 22 tight, avoiding deviation or shaking during the vehicle driving process, and ensuring the stability of the device.

[0024] As the first gear 26 advances, the clamping block 2301 compresses the elastic piece 2302 inward, causing the elastic piece 2302 to deform. The clamping block 2301 retracts into the threaded rod 23. When the first gear 26 passes over the protruding part of the clamping block 2301, the clamping block 2301 pops out outward under the elastic force of the elastic piece 2302 and is stuck outside the first gear 26, preventing the movable seat 24 from moving back and forth, and also ensuring the pressing effect of the movable seat 24 on the installation block 15. Through the above technical solution, the device can be quickly installed or disassembled, realizing multi-directional limiting of the device.

[0025] Further, a stabilizing mechanism 3 is connected to the connecting block 14. The stabilizing mechanism 3 includes a first rotating shaft 31 and a second rotating shaft 32. The first rotating shaft 31 and the second rotating shaft 32 are respectively rotatably connected to the connecting blocks 14 on both sides. Fixed sleeves of transmission wheels 33 are sleeved on the shaft bodies at one ends of the first rotating shaft 31 and the second rotating shaft 32. A transmission belt 34 is sleeved on the two transmission wheels 33. Threaded connection parts 3101 are arranged on the shaft bodies at the other ends of the first rotating shaft 31 and the second rotating shaft 32. A limiting plate 35 is threadedly connected to the threaded connection part 3101. The limiting plate 35 abuts against one side of the movable seat 24. Worms 36 are fixedly sleeved at both ends of the first rotating shaft 31 and the second rotating shaft 32. Worm wheels 37 are meshed and connected to the bottoms of the worms 36. The worm wheels 37 are rotatably connected to the connecting blocks 14. A limiting tooth plate 38 is fixedly connected to one side of the worm wheel 37. A positioning block 39 is fixedly connected to the lower surface of the limiting tooth plate 38.

[0026] Specifically, synchronous transmission is achieved between the first rotating shaft 31 and the second rotating shaft 32 through the transmission wheels 33 and the transmission belt 34. When the first rotating shaft 31 is rotated, the second rotating shaft 32 rotates synchronously. Through the threaded fit between the threaded connection part 3101 and the limiting plate 35, the limiting plate 35 moves towards the direction close to the movable seat 24 until the movable seat 24 is tightly abutted, so that the movable seat 24 is fixed between the limiting plate 35 and the baffle 21, further improving the stability and reliability of the movable seat 24.

[0027] During the rotation of the first rotating shaft 31 and the second rotating shaft 32, the worm 36 rotates synchronously, driving the worm wheel 37 to rotate. The worm wheel 37 drives the limiting tooth plate 38 and the positioning block 39 to rotate. When the limiting tooth plate 38 meshes with the second gear 42, the positioning block 39 is correspondingly clamped with the positioning ball 43. Through the above technical solution, on the one hand, the positioning block 39 is clamped with the positioning ball 43, making the upper part of the limiting tooth plate 38 vertically fixed, playing a role in supporting and fixing the four corners of the housing 1, ensuring the smoothness of the four corners of the housing 1 and avoiding shaking. On the other hand, the limiting tooth plate 38 meshes with the second gear 42, which can prevent the second gear 42 and the bolt 41 from rotating, and further prevent the connection between the bolt 41 and the vehicle body installation part from loosening, further improving the stability of the mounting plate 4.

[0028] Further, bolts 41 penetrate through the four corners of the mounting plate 4. Second gears 42 are fixedly connected to the tops of the bolts 41. A positioning ball 43 is fixedly connected to one side of the upper part of the bolt 41. The limiting tooth plate 38 meshes with the second gear 42. The positioning block 39 abuts against the positioning ball 43. A ratchet wheel 310 is fixedly sleeved at one end of the first rotating shaft 31. A ratchet pawl 311 is meshed and connected to the upper end of the ratchet wheel 310. One end of the ratchet pawl 311 is fixedly connected to the connecting block 14.

[0029] Specifically, the positioning ball 43 is correspondingly clamped with the positioning block 39. By setting the positioning ball 43, the final orientation of the second gear 42 can be determined, ensuring good meshing between the limit tooth plate 38 and the second gear 42 after the limit tooth plate 38 rotates downwards.

[0030] In this application, by providing a ratchet 310 and a ratchet pawl 311 at one end of the first rotating shaft 31, the rotation of the first rotating shaft 31 can be avoided, improving the reliability of transmission and structural connection.

[0031] As Figures 1 - 12 shown, a usage method of an anti-shake vehicle-mounted router provided by an embodiment of the present invention includes the following steps: Fix the mounting plate 4 at a specified position on the vehicle, place the mounting block 15 in the mounting groove 2201, correspondingly insert the movable seat 24 into the limit seat 22, move the movable seat 24 in the direction close to the baffle 21, the movable seat 24 pushes the mounting block 15 to move, so that one end of the mounting block 15 abuts against the side wall of the mounting groove 2201. At the same time, the insertion block 2401 is correspondingly inserted into the slot 2101, the first gear 26 is sleeved on the threaded rod 23 and then rotates, the two racks 27 move relatively, so that the inner side walls of the movable seat 24 are close to the limit seat 22, making the connection between the movable seat 24 and the limit seat 22 tight. When the first gear 26 passes over the protruding part of the latch 2301, the latch 2301 pops outwards under the elastic force of the elastic piece 2302 and is stuck outside the first gear 26 to prevent the movable seat 24 from moving back and forth. Then rotate the first rotating shaft 31 to make the limit plate 35 move in the direction close to the movable seat 24 until the movable seat 24 is abutted tightly. At the same time, the worm 36 drives the worm wheel 37 to rotate, the worm wheel 37 drives the limit tooth plate 38 and the positioning block 39 to rotate, the limit tooth plate 38 meshes with the second gear 42, the positioning block 39 is correspondingly clamped with the positioning ball 43, the limit tooth plate 38 is vertically fixed, which plays a role in supporting and fixing the four corners of the housing 1, ensuring the stability of the four corners of the housing 1, and preventing the second gear 42 and the bolt 41 from rotating, thereby avoiding the loosening of the connection between the bolt 41 and the vehicle body installation part, and further improving the stability of the mounting plate 4.

[0032] When the vehicle starts, the vehicle-mounted power supply supplies power to the router, the processor starts to run, responsible for controlling and coordinating various functions of the router. The wireless communication module works under the instruction of the processor, transmits and receives signals through the antenna 12. The antenna 12 transmits the received external network signals to the wireless communication module, and after the wireless communication module processes these signals, it is transmitted to the processor for further data processing and analysis; When in-vehicle equipment needs to connect to the network, it establishes a connection with the router through the interface 13 at one end. After the processor recognizes the connection request of the equipment, it allocates network resources for it and realizes data interaction between the equipment and the external network through the wireless communication module and the antenna 12.

[0033] In summary, the anti-shake vehicle-mounted router can be conveniently installed and disassembled by setting the movable seat 24 and the limit seat 22 to be slidably plugged. The threaded rod 23 is threadedly matched with the first gear 26 to drive the two racks 27 to move relative to each other, so that the two inner side walls of the movable seat 24 are close to the limit seat 22, so that the movable seat 24 is tightly connected with the limit seat 22, and the deviation or shaking during the driving of the vehicle is avoided, and the stability of the equipment is ensured. The first rotating shaft 31 is rotated to make the limit plate 35 close to the movable seat 24, and the stability of the movable seat 24 is further improved. The worm 36 rotates with the first rotating shaft 31, driving the worm wheel 37 to rotate, so that the limit tooth plate 38 and the positioning block 39 rotate downward, and the limit tooth plate 38 is meshed with the second gear 42 to avoid the second gear 42 from rotating, thereby improving the stability of the installation. The positioning block 39 is engaged with the positioning ball 43, so that the upper part of the limit tooth plate 38 is vertically fixed, which plays a role in supporting and fixing the four corners of the shell 1, and ensures the stability of the four corners of the shell 1 to avoid shaking.
