Description

Technical Field

[0001] This application belongs to the field of RTK technology, and specifically relates to an RTK antenna device. Background Technology

[0002] Currently, there are two main methods for fixing RTK antennas in the market: one is direct plugging and unplugging, which can cause the RTK antenna to wobble under radial force; the other is threaded fixing, where the antenna is directly screwed onto the RTK socket. This method can lead to failure of the threaded connection after repeated installations. Furthermore, fixing the RTK antenna directly to the external device can cause the antenna to be too close to the device, and the signal may be affected by magnets or electrical signals inside the device. In addition, other components in the RTK antenna device are usually fixed with glue, but glue is easily affected by high and low temperatures and / or aging over time, which can lead to fixation failure.

Detailed Implementation

[0018] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0019] An embodiment of this application provides an RTK antenna device, which includes: Base module 1 is used to be mounted on the device 2 to be connected; Extension rod module 3 is mounted on base module 1; RTK antenna 4 is located at the end of extension rod module 3 away from base module 1, and the length of extension rod module 3 is at least twice the length of RTK antenna 4; The connecting line 5 is located inside the base module 1 and the extension rod module 3, and its two ends are connected to the device to be connected 2 and the RTK antenna 4 respectively. The connecting line 5 is used to transmit signals between the device to be connected 2 and the RTK antenna 4.

[0020] Specifically, such as Figures 1-2As shown, in this embodiment, the RTK antenna 4 has a dome-shaped structure (i.e., the upper part is a dome-shaped structure, and the lower part is a cylindrical structure, with the upper and lower parts connected to form the RTK antenna 4). In this embodiment, the length of the RTK antenna 4 is 100mm, and the length of the extension rod module 3 is 200mm. The overall orientation of the extension rod module 3 is perpendicular to the orientation of the side of the device 2 to be connected to the RTK antenna device (e.g., ...). Figure 1 , Figure 3 , Figure 5 As shown), the connecting cable 5 passes through the base module 1 and the extension rod module 3 and can transmit signals between the RTK antenna 4 and the device to be connected 2. The overall installation process of this RTK antenna device is as follows: Figures 8-16 As shown.

[0021] In this embodiment, the RTK antenna device, by setting the extension rod module 3 and the connecting line 5, keeps the RTK antenna 4 away from the device to be connected 2, effectively avoiding the influence of the magnetic or electrical signals of the device to be connected 2 on the RTK antenna 4. At the same time, the connecting line 5 is located inside the base module 1 and the extension rod module 3 and is not exposed in appearance. This internal wiring setting improves the appearance and reliability of the RTK antenna device.

[0022] In one embodiment of this application, the base module 1 is detachably connected to the device 2 to be connected.

[0023] Specifically, the base module 1 and the device to be connected 2 are connected by bolt assembly, which ensures the reliability of the connection between the base module 1 and the device to be connected 2. At the same time, the detachable connection makes the base module 1 easy to disassemble and maintain.

[0024] In one embodiment of this application, the base module 1 includes: The base 101 is connected to the device 2 to be connected via the first bolt assembly 102; The bottom of the first housing 103 is connected to the base 101 via the second bolt assembly 104; The first fixing bracket assembly 105 is disposed inside the first housing 103 and includes a first fixing bracket 106 and a first fixing cover 107. The first fixing bracket 106 and the first fixing cover 107 are distributed opposite to each other and connected to the first housing 103 by a fourth bolt assembly 109. The first fixing bracket 106 is connected to the first fixing cover 107 by a third bolt assembly 108 and together with the first fixing cover 107, forms a first installation space 110. A portion of the extension rod module 3 passes through the top wall of the first housing 103 and extends into the first installation space 110. The first fixing bracket 106 is connected to the extension rod module 3 by a fifth bolt assembly 111.

[0025] Specifically, such as Figure 2 , Figure 8As shown, when installing the base module 1 of the RTK antenna device, the base 101 is first fixed to the device 2 to be connected using the first bolt assembly 102. In this embodiment, the first bolt assembly 102 can be selected as two M2x4 screws; as Figure 10 As shown, the fifth bolt assembly 111 can be selected as two M3x5 screws. The first fixing bracket 106 has two vertically distributed M3 threaded holes, and the extension rod module 3 has two mounting holes corresponding to the positions of the M3 threaded holes. The two M3x5 screws pass through the M3 threaded holes and the mounting holes respectively, so that the first fixing bracket 106 is fixed by the fifth bolt assembly 111, and self-tapping threads are formed in the mounting holes; as shown. Figure 11 As shown, the third bolt assembly 108 can be selected as four M2x4 screws. The first fixing bracket 106 and the first fixing cover 107 each have four M2 threaded holes formed on their axial sides. The four M2x4 screws pass sequentially through the M2 threaded holes on the first fixing bracket 106 and the first fixing cover 107 to connect the first fixing bracket 106 and the first fixing cover 107. The first fixing bracket 106 and the first fixing cover 107 together form a cylindrical first mounting space 110. Figure 12 As shown, the fourth bolt assembly 109 can be selected as four M2x4 screws. The bottom ends of the first fixing bracket 106 and the first housing 103 each have four M2 threaded holes. The four M2x4 screws pass through the first fixing bracket 106 and the first housing 103 in sequence, allowing the first housing 103 to be fitted onto the outside of the first fixing bracket assembly 105 and fixed in place. The bolt assembly further ensures the reliability of the RTK antenna device's connection and the convenience of disassembly and maintenance by connecting the above components. The first housing 103 covers part of the bolt assembly, enhancing the aesthetic appearance of the RTK antenna device.

[0026] Furthermore, the first housing 103, the first fixing bracket 106, and the first fixing cover 107 are all made of aluminum alloy. Aluminum alloy has high strength and low density, which ensures the overall structural reliability of the RTK antenna device while making the RTK antenna device relatively lightweight.

[0027] In one embodiment of this application, the extension rod module 3 includes: Extension rod 301, the first end of extension rod 301 passes through the top wall of the first housing 103 and extends into the first mounting space 110, and the first fixing bracket 106 is connected to extension rod 301 by the fifth bolt assembly 111; The second mounting bracket assembly 302 is sleeved on the second end of the extension rod 301 and includes a second mounting bracket 303 and a second mounting cover 304. The second mounting bracket 303 and the second mounting cover 304 are distributed opposite to each other and connected by a sixth bolt assembly 305. One end of the connecting line 5 near the RTK antenna 4 is set on the second mounting bracket 303. The second mounting bracket 303 is connected to the extension rod 301 by an eighth bolt assembly 312. The second housing 306 is sleeved on the outside of the second fixing frame assembly 302 and connected to the second fixing frame 303 via the seventh bolt assembly 311.

[0028] Specifically, the first end of the extension rod 301 has two mounting holes corresponding to the positions of the M3 threaded holes on the first fixing bracket 106, and these holes can form self-tapping threads when the first fixing bracket 106 is connected to the extension rod 301; for example Figure 4 , Figure 7 , Figure 13 As shown, the eighth bolt assembly 312 can be selected as two M3x5 screws. The second fixing bracket 303 has two M3 threaded holes, and the second end of the extension rod 301 has two mounting holes corresponding to the positions of the M3 threaded holes on the second fixing bracket 303. The two M3x5 screws pass through the threaded holes and mounting holes respectively, forming a fixed connection between the second fixing bracket 303 and the extension rod 301. Simultaneously, a self-tapping thread is formed in the mounting hole at the second end of the extension rod 301. Figure 14 As shown, the sixth bolt assembly 305 can be selected as two M2x4 screws. Two M2 threaded holes are formed on both axial sides of the second fixing bracket 303 and the second fixing cover 304, respectively. The two M2x4 screws pass through the M2 threaded holes on the second fixing cover 304 and the second fixing bracket 303 in sequence, thus forming a fixed connection between the second fixing bracket 303 and the second fixing cover 304. Figure 15 As shown, before installing the second mounting bracket assembly 302 onto the extension rod 301, the second housing 306 is fitted onto the extension rod 301. After installing the second mounting bracket assembly 302 onto the extension rod 301, the second housing 306 is then connected to the second mounting bracket 303. The seventh bolt assembly 311 can be selected as four M2x4 screws. Four M2 threaded holes are formed on the top end face of the second mounting bracket 303, and four M2 threaded holes are formed inside the second housing 306. The four M2x4 screws pass through the M2 threaded holes on the second mounting bracket 303 and the M2 threaded holes on the second housing 306 in sequence, thus forming a fixed connection between the second housing 306 and the second mounting bracket 303. The bolt assembly connecting the above components further ensures the connection reliability and ease of disassembly and maintenance of the RTK antenna device. The second housing 306 covers the bolt assembly in the second mounting bracket assembly 302, enhancing the aesthetic appearance of the RTK antenna device.

[0029] Furthermore, the second housing 306, the second mounting bracket 303, and the second mounting cover 304 are all made of aluminum alloy, which further ensures the overall structural reliability of the RTK antenna device while making the RTK antenna device lighter overall.

[0030] In one embodiment of this application, a first positioning post portion 112 extending in the direction of the extension rod 301 is formed on the first fixing cover 107, and a first positioning hole 308 is formed for at least a portion of the first positioning post portion 112 to extend into.

[0031] Specifically, such as Figure 2 , Figure 4 , Figure 6 As shown, the first positioning post 112 on the first fixed cover 107 matches the cross-sectional size of the first positioning hole 308 on the first end of the extension rod 301. The first positioning post 112 extending into the first positioning hole 308 can make the first fixed cover 107 form an installation limit on the extension rod 301. The above settings enhance the overall installation accuracy of the RTK antenna device.

[0032] In one embodiment of this application, a second positioning post portion 309 extending in the direction of the extension rod 301 is formed on the second fixing cover 304, and a second positioning hole 310 is formed on the extension rod 301 for at least a portion of the second positioning post portion 309 to extend into.

[0033] Specifically, such as Figure 2 , Figure 4 , Figure 7 As shown, the second positioning post 309 on the second fixing cover 304 matches the cross-sectional dimensions of the second positioning hole 310 on the second end of the extension rod 301. The second positioning post 309 extending into the second positioning hole 310 can enable the second fixing cover 304 to form an installation limit on the extension rod 301. The above settings further enhance the accuracy of the overall installation of the RTK antenna device.

[0034] In one embodiment of this application, the first fixing frame 106 and the first fixing cover 107 are both interference-fitted with the extension rod 301, and the second fixing frame 303 and the second fixing cover 304 are both interference-fitted with the extension rod 301.

[0035] Specifically, the first mounting space 110 formed by the first mounting bracket 106 and the first mounting cover 107 is cylindrical, and the cross-sectional diameter of the first mounting space 110 is smaller than the diameter of the extension rod 301, thereby forming an interference fit between the first mounting bracket 106, the first mounting cover 107 and the extension rod 301; the second mounting bracket 303 and the second mounting cover 304 together form a cylindrical second mounting space, and the cross-sectional diameter of the second mounting space is smaller than the diameter of the extension rod 301, thereby forming an interference fit between the second mounting bracket 303, the second mounting cover 304 and the extension rod 301. The above configuration further enhances the reliability of the overall structure of the RTK antenna device.

[0036] In one embodiment of this application, the RTK antenna device further includes an adapter 6 that is inserted into a socket 7 of the device to be connected 2 and is communicatively connected to the socket 7. One end of the connecting line 5 near the device to be connected 2 is threadedly connected to the adapter 6 and is communicatively connected to the adapter 6. The other end of the connecting line 5 near the RTK antenna 4 protrudes from the top wall of the second mounting bracket 303 and is threadedly connected to the RTK antenna 4.

[0037] Specifically, such as Figure 2 , Figure 9 , Figure 16 As shown, after fixing the base 101 to the device 2 to be connected, one end of the adapter 6 is connected to the end of the connecting cable 5 near the device 2. The end of the connecting cable 5 near the device 2 has an internal thread, and this end of the adapter 6 has an external thread. The internal thread of the connecting cable 5 matches the external thread of the adapter 6, allowing them to form a fixed connection. Simultaneously, the adapter can transmit signals. Figure 2 , Figure 4 , Figure 10 As shown, an annular first groove is formed at one end of the connecting line 5 near the RTK antenna 4. The top of the second fixing bracket 303 can be partially inserted into the first groove, thereby limiting and fixing the connecting line 5 and the second fixing bracket 303. The part of the connecting line 5 protruding from the top wall of the second fixing bracket 303 has an external thread, and the bottom end of the RTK antenna 4 has an internal thread. The external thread of the connecting line 5 matches the internal thread of the RTK antenna 4 and enables the two to form a fixed connection.

[0038] In one embodiment of this application, the extension rod 301 is made of carbon fiber.

[0039] Specifically, carbon fiber has a much lower density than metal materials, and it also has high strength and high stiffness. These characteristics not only make the RTK antenna device lightweight, but also ensure the durability of the extension rod 301. In addition, carbon fiber is non-magnetic, which can avoid electromagnetic interference from the extension rod 301 to the RTK antenna 4, thus ensuring the quality of the transmitted signal.

[0040] In one embodiment of this application, the RTK antenna device further includes a buffer ring 8 disposed inside the second housing 306 for buffering impacts on the RTK antenna 4.

[0041] Specifically, such as Figure 2 , Figure 4 , Figure 16As shown, a second annular groove is formed on the top of the second housing 306, and a buffer ring 8 is placed in the second groove. When the connecting line 5 is connected to the RTK antenna 4, the top of the buffer ring 8 contacts the RTK antenna 4. In this embodiment, the buffer ring 8 can be made of silicone, which has a certain elasticity to buffer the impact of the RTK antenna 4. Furthermore, the depth of the second groove is less than the thickness of the buffer ring 8. When the buffer ring 8 contacts both the second housing 306 and the RTK antenna 4, the buffer ring 8 will be compressed, thereby generating a continuous axial clamping force. This increases the friction at the threaded connection between the connecting line 5 and the RTK antenna 4, thus preventing the screw from loosening.
