Description

Technical Field

[0001] The present invention relates to the technical field of intelligent sensing terminals, and particularly to an antenna structure that can maintain a vertically upward state. Background Art

[0002] The Beidou intelligent sensing terminal is a device based on the independently developed Beidou satellite navigation system (BDS) in China. It can receive signals from Beidou satellites to determine information such as position, speed, and time. Such terminals usually integrate multiple functions and technologies. The Beidou intelligent sensing terminal has characteristics such as high-precision positioning, short message communication, sensor fusion, Internet of Things (IoT) interfaces, and low-power design. High-precision positioning is reflected in the use of multi-frequency signals of the Beidou system to achieve centimeter-level or even higher positioning accuracy; short message communication means that short messages can be sent in the absence of other communication means; sensor fusion technology means that the intelligent sensing terminal integrates various types of sensors (such as accelerometers, gyroscopes, magnetometers, etc.), and improves positioning accuracy and service performance through sensor data fusion technology; to meet the development needs of the Internet of Things (IoT), many terminals provide rich interfaces to connect different IoT devices to form an intelligent network; considering portability and the need for long-term operation, these terminals often adopt efficient power management solutions to extend battery life.

[0003] The antenna is a key component for the Beidou intelligent sensing terminal to receive and send signals. It is responsible for communicating with the Beidou satellite navigation system (BDS) and other possible supported global navigation satellite systems (such as GPS, GLONASS, Galileo, etc.). Keeping the antenna always upward can better receive signals. The BT-3707A antenna is a four-star multi-frequency aviation antenna with characteristics of high gain and low wind resistance. It is small in size, beautiful in appearance, highly sensitive, and low in power consumption, greatly improving the accuracy and speed of positioning for high-speed moving carriers. It can be used with a variety of receivers and is widely applied in fields such as navigation scheduling, tracking and monitoring, and measurement and control. It is especially suitable for high-speed mobile systems and fields, such as civilian drones and vehicle-mounted high-precision applications.

[0004] This antenna can also be used with a variety of satellite navigation receivers to meet the requirements of positioning and speed measurement for moving carriers in high-dynamic environments, and is widely applied in fields such as navigation scheduling, tracking and monitoring, measurement and control, and military. It has the following advantages: 1. The low-noise amplifier has high gain and can be connected to a long cable; 2. The outer cover is made of high-temperature resistant plastic material and protects the internal circuit through heat insulation design; 3. It adopts an overall waterproof design with a waterproof level reaching IP67.

[0005] To maintain the antenna in an upward position at all times, the antenna is adjusted by rotating the connecting rod. After adjustment, the antenna and the connecting rod are fixed by a locking mechanism to prevent the antenna from rotating and deviating from directly above. However, most traditional locking mechanisms use screws to pass through the connecting rod to fix the connecting rod and the antenna. When fine adjustment of the antenna is required, the screws need to be unscrewed first, and the locking mechanism needs to be removed before adjustment. After adjustment, the screws need to be screwed on again, and the locking mechanism needs to be fixed on the connecting rod, which is rather troublesome to operate. Summary of the Invention

The limiting block slides in the limiting groove to prevent relative rotation between the outer ring and the support. Description of the Drawings

The end of the convex rod 331 is located in the chute 342 and is slidably connected to the lock block 341.

[0052] The spring 344 is located in the chute 342. One end of the spring 344 is fixedly connected to the left end of the lock block 341, and the other end is fixedly connected to the convex rod 331. The clamping parts 343 are rotatably arranged on both sides of the lock block 341.

[0053] The clamping part 343 includes a clamping body group, a locking part 345 and a groove 346. The clamping body group includes a clamping body 3431, a connecting shaft 3432, a column 3433 and a convex ring 3434. The connecting shaft 3432 is fixedly connected to the clamping body 3431 and is rotatably connected to the lock block 341. A first torsion spring for the reset of the connecting shaft 3432 is provided inside the connecting shaft 3432. The column 3433 is rotatably arranged outside the tail of the clamping body 3431. The convex ring 3434 is fixedly sleeved on the outer circle of the column 3433. A clockwork spring for the reset of the column 3433 is provided inside the column 3433. A number of conical blocks 3435 are fixedly provided on the outer circle of the convex ring 3434. The shape of the conical blocks 3435 is the same as that of the conical groove 334 and the position is opposite to that of the conical groove 334. When the push rod 332 touches the convex ring 3434, the conical blocks 3435 are inserted into the corresponding conical grooves 334 to prevent relative rotation between the push rod 332 and the convex ring 3434, so that the column 3433 cannot be driven to rotate, resulting in the pulling rope 348 not being able to be wound around the column 3433. A rubber protection layer is fixedly provided on the outer circle of the convex ring 3434 to increase the friction between the convex ring 3434 and the push rod 332, further preventing relative movement between the two and avoiding the convex ring 3434 being unable to rotate self. The groove 346 is arranged on the front side surface of the clamping body 3431. The locking part 345 is rotatably arranged in the groove 346. A cavity 349 is provided inside the clamping body 3431. The cavity 349 communicates with the groove 346. A pulling rope 348 and a number of guide wheels 347 are provided inside the cavity 349. The guide wheels 347 are all rotatably connected to the clamping body 3431. One end of the pulling rope 348 is fixedly connected to the convex ring 3434. After sequentially passing around the connecting shaft 3432 and each guide wheel 347, the other end is fixedly connected to the pull rod 3453. The guide wheels 347 guide the pulling rope 348 to reciprocate horizontally. The cross-section of the guide wheel 347 is V-shaped. The pulling rope 348 is located in the V-shaped groove of the guide wheel 347 to prevent the pulling rope 348 from falling off the guide wheel 347.

[0054] When the push rod 332 pushes the convex ring 3434 to rotate, it drives the pulling rope 348 to wind around the column 3433. The pulling rope 348 becomes shorter and pulls the pull rod 3453, causing the locking body 3451 to rotate around the connecting column 3454. When the push rod 332 no longer pushes the convex ring 3434, the clockwork spring drives the convex ring 3434 to rotate back. The pulling rope 348 rotates away from the column 3433 and becomes longer, reducing the pulling force on the pull rod 3453. The second torsion spring drives the locking body 3451 to reset.

[0055] The locking part 345 includes a locking body 3451, a locking tip 3452, a pull rod 3453 and a connecting column 3454. The locking tip 3452 is fixedly provided at the front end of the locking body 3451. The pull rod 3453 is fixedly provided in the middle of the locking body 3451. The connecting column 3454 is fixedly provided at the tail of the locking body 3451 and is rotatably connected to the clamping body 3431. A second torsion spring for the reset of the connecting column 3454 is provided inside the connecting column 3454.

[0056] When it is necessary to adjust the distance between the suction cup part 2 and the support part 1, push the outer ring 32 towards the suction cup part 2. The outer ring 32 drives the convex rod 331 to slide backward along the chute 342, the spring 344 is compressed, and the convex rod 331 drives the push rod 332 to move backward synchronously. When the push rod 332 contacts the convex ring 3434, since a layer of rubber is wrapped on the outer surface of the convex ring 3434, the frictional force between the convex ring 3434 and the push rod 332 is relatively large. At the same time, the conical block 3435 is inserted into the corresponding conical groove 334, pushing the convex ring 3434 to rotate. There will be no relative sliding between the convex ring 3434 and the push rod 332. The push rod 332 pushes the convex ring 3434 to rotate around the column 3433, and the clockwork spring inside the column 3433 is tightened. The pull rope 348 between the column 3433 and the pull rod 3453 is wound around the column 3433, the pull rope 348 becomes shorter, and the pull rod 3453 pulls the lock body 3451 to rotate around the connecting column 3454. The second torsion spring inside the connecting column 3454 is deformed, and the lock tip 3452 rotates out of the pointed groove inside the card slot 14. When the convex ring 3434 rotates, it is pushed backward by the push rod 332. The convex ring 3434 pushes the column 3433 to move backward synchronously. Since the connecting shaft 3432 is rotatably connected to the lock block 341, the column 3433 drives the clamping body 3431 to rotate around the connecting shaft 3432. The first torsion spring inside the connecting shaft 3432 is deformed, and the end of the clamping body 3431 rotates out of the card slot 14. The clamping part 343 leaves the adjusting rod 12 and loses the restriction on the adjusting rod 12;

[0057] Then manually hold the support 11 and rotate the adjusting nut 13 in the clockwise direction. The adjusting nut 13 drives the adjusting rod 12 to move leftward, the suction cup part 2 moves away from the support part 1, and the distance between the two increases. Rotate the adjusting nut 13 in the counterclockwise direction, the adjusting nut 13 drives the adjusting rod 12 to move rightward, the suction cup part 2 approaches the support part 1, and the distance between the two decreases. After adjusting the distance between the suction cup part 2 and the support part 1, rotate the suction cup 21 to make the suction cup 21 in a vertically upward state, and adsorb the suction cup 21 on the vehicle. Loosen the outer ring 32, the spring 344 rebounds, pushing the convex rod 331 to move forward along the chute 342. The convex rod 331 drives the push rod 332 to move forward synchronously, no longer squeezing the convex ring 3434. The first torsion spring in the connecting shaft 3432 rebounds, driving the clamping body 3431 to rotate. The tip of the clamping body 3431 is inserted into the card slot 14, fixing the locking mechanism 3 on the adjusting rod 12. The suction cup part 2 is also fixed on the adjusting rod 12 through the locking mechanism 3, preventing the adjusting rod 12 from rotating and unable to maintain a fixed distance between the antenna body 5 and the support 11. At the same time, the clockwork spring in the column 3433 rebounds, driving the convex ring 3434 to reverse, the pull rope 348 elongates, the pulling force of the pull rope 348 on the pull rod 3453 decreases, the second torsion spring in the connecting column 3454 rebounds, driving the locking body 3451 to rotate, and the locking tip 3452 extends into the tip groove inside the card slot 14, further strengthening the connection strength between the locking mechanism 3 and the adjusting rod 12. When the vehicle shakes, the support 11 drives the antenna body 5 to rotate around the adjusting rod 12. Since the adjusting rod 12 is above the center of gravity of the support 11, the support 11 slowly stops under its own weight, and the end with the antenna body 5 installed faces upward. The antenna body 5 is directly above the center of gravity of the support 11. Therefore, in the stationary state of the support 11, the antenna body 5 is vertically upward.

[0058] Embodiment 2

[0059] The difference between this embodiment and Embodiment 1 is that a counterweight 6 is fixedly provided at the bottom inside the support 11. The counterweight 6 is used to increase the mass of the support part 1 and lower its center of gravity. When the vehicle is tilted, under the action of the gravity of the counterweight 6, the support 11 will automatically rotate back to its original position along the adjusting rod 12, so that the antenna body 5 always remains vertically upward.

[0060] The above is only the preferred embodiment of the present invention, and it does not impose any form of limitation on the present invention. Although the present invention has been disclosed as above with the preferred embodiment, it is not used to limit the present invention. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to make equivalent embodiments with equivalent changes within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any brief modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
