Description

Technical Field

[0001] The present invention relates to the technical field of intelligent sensing terminals, and in particular to an antenna structure capable of maintaining a vertical upward state. Background Art

[0002] Beidou intelligent sensing terminal is a device based on the Beidou satellite navigation system (BDS) independently developed by China. It can receive signals from Beidou satellites to determine information such as location, speed and time. This type of terminal usually integrates multiple functions and technologies. Beidou intelligent sensing terminal has the characteristics of high-precision positioning, short message communication, sensor fusion, Internet of Things interface 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 refers to the ability to send short messages without other communication means; sensor fusion technology refers to the integration of various types of sensors (such as accelerometers, gyroscopes, magnetometers, etc.) in intelligent sensing terminals, and improves positioning accuracy and service performance through sensor data fusion technology; in order to adapt to 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 the need for portability and long-term work, these terminals often use 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 global navigation satellite systems that may be supported (such as GPS, GLONASS, Galileo, etc.). The antenna is always facing upward to receive signals better. The BT-3707A antenna is a four-star multi-frequency aviation antenna with high gain and low wind type characteristics. It is small in size, exquisite in appearance, high in sensitivity, and low in power consumption. It greatly improves the accuracy and speed of positioning high-speed moving carriers. It can be used with a variety of receivers and is widely used in navigation scheduling, tracking monitoring, measurement and control, etc. It is especially suitable for high-speed mobile systems and fields, such as civil drones and vehicle-mounted high-precision applications.

[0004] The antenna can also be used with a variety of satellite navigation receivers to meet the requirements of positioning and speed measurement of moving carriers in high dynamic environments, and is widely used in navigation scheduling, tracking monitoring, measurement and control, and military fields. It has the following advantages: 1. Low noise and high gain, can be connected to long-distance antennas; 2. The outer cover is made of high-temperature resistant plastic material, and the internal circuit is protected by heat insulation design; 3. It adopts an overall waterproof design, and the waterproof level reaches I F67.

[0005] In order to keep the antenna always pointing upward, the antenna is adjusted by rotating the connecting rod. After the adjustment, the antenna and the connecting rod are fixed together by a locking mechanism to prevent the antenna from rotating away from the upper side. However, most traditional locking mechanisms use screws to pass through the connecting rod to fix the connecting rod and the antenna. When the antenna needs to be fine-tuned, the screws need to be unscrewed first, and the locking mechanism needs to be removed before adjustment. After adjustment, the screws need to be tightened again, and then the locking mechanism needs to be fixed to the connecting rod, which is more troublesome to operate. Summary of the invention

[0047] The adjusting nut 13 is sleeved on the right end of the adjusting rod 12 and is threadedly connected to the adjusting rod 12. The adjusting nut 13 is rotatably connected to the outer wall of the support 11. The slots 14 are all located on the outer circle of the right end of the adjusting rod 12.

[0052] The spring 344 is located in the slide groove 342 , one end of the spring 344 is fixedly connected to the left end of the locking block 341 , and the other end of the spring 344 is fixedly connected to the protruding rod 331 , and the clamping parts 343 are rotatably arranged on both sides of the locking 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 locking block 341. A first torsion spring for resetting the connecting shaft 3432 is provided in the connecting shaft 3432. The column 3433 is rotatably arranged on the outer side of the tail of the clamping body 3431. The convex ring 3434 is fixedly sleeved on the column 3433. The outer ring of the convex ring 3434 is provided with a spring for resetting the column 3433. The outer ring of the convex ring 3434 is fixed with a plurality of conical blocks 3435. The conical blocks 3435 have the same shape as the conical groove 334 and are located opposite to the conical groove 334. When the push rod 332 contacts the convex ring 3434, the conical blocks 3435 are inserted into the corresponding conical groove 334 to prevent the push rod 332 and the convex ring 3434 from rotating relative to each other, and thus cannot drive the column 3433 to rotate, resulting in the pulling. The rope 348 cannot be wound around the column 3433. The outer ring of the convex ring 3434 is fixed with a rubber protective layer to increase the friction between the convex ring 3434 and the push rod 332, further preventing the relative movement between the two and preventing the convex ring 3434 from being unable to rotate. The groove 346 is provided on the side of the front end of the clamping body 3431, and the locking part 345 is rotatably arranged in the groove 346. The clamping body 3431 is provided with a cavity 349, which is connected to the groove 346, and the cavity 349 is provided with a pull rope 3 48 and a plurality of guide wheels 347, the guide wheels 347 are rotatably connected to the clamping body 3431, one end of the pull rope 348 is fixedly connected to the convex ring 3434, and after passing around the connecting shaft 3432 and each guide wheel 347 in turn, the other end is fixedly connected to the pull rod 3453, the guide wheel 347 guides the pull rope 348 to make it reciprocate horizontally, the cross-section of the guide wheel 347 is V-shaped, the pull rope 348 is located in the V-shaped groove of the guide wheel 347, to prevent the pull rope 348 from falling off from the guide wheel 347.

[0054] When the push rod 332 pushes the convex ring 3434 to rotate, it drives the pull rope 348 to wrap around the column 3433, the pull rope 348 becomes shorter, and the pull rod 3453 is pulled to make the lock body 3451 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, the pull rope 348 rotates away from the column 3433 and becomes longer, the pulling force on the pull rod 3453 is reduced, and the second torsion spring drives the lock body 3451 to reset.

[0055] The locking portion 345 includes a locking body 3451, a locking tip 3452, a pull rod 3453 and a connecting column 3454. The locking tip 3452 is fixed at the front end of the locking body 3451, the pull rod 3453 is fixed at the middle of the locking body 3451, the connecting column 3454 is fixed at the rear end of the locking body 3451, and is rotatably connected to the locking body 3431. A second torsion spring is provided in the connecting column 3454 for resetting the connecting column 3454.

[0056] When the distance between the suction cup part 2 and the support part 1 needs to be adjusted, the outer ring 32 is pushed toward the suction cup part 2, and the outer ring 32 drives the convex rod 331 to slide backward along the slide groove 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 the outer surface of the convex ring 3434 is wrapped with a layer of rubber, the friction 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 to push the convex ring 3434 to rotate. The convex ring 3434 and the push rod 332 will not slide relative to each other. The push rod 332 drives the convex ring 3434 to rotate around the column 3433, and the clockwork spring in the column 3433 is tightened. The pull rope 348 is wound around the column 3433, the pull rope 348 becomes shorter, and the locking body 3451 is pulled to rotate around the connecting column 3454 through the pull rod 3453, the second torsion spring in the connecting column 3454 is deformed, the locking tip 3452 rotates out of the tip groove inside the slot 14, the convex ring 3434 is pushed to move backward by the push rod 332 during its rotation, and the convex ring 3434 pushes the column 3433 to move backward synchronously, and since the connecting shaft 3432 is rotationally connected with the locking block 341, the column 3433 drives the locking body 3431 to rotate around the connecting shaft 3432, the first torsion spring in the connecting shaft 3432 is deformed, the end of the locking body 3431 rotates out of the slot 14, and the locking portion 343 leaves the adjusting rod 12, losing the restriction on the adjusting rod 12;

[0057] The adjusting nut 13 is then manually held on the support 11, and the adjusting nut 13 is turned in the clockwise direction, and the adjusting nut 13 drives the adjusting rod 12 to move to the left, and the suction cup part 2 is away from the support part 1, and the distance between the two increases; the adjusting nut 13 is turned in the counterclockwise direction, and the adjusting nut 13 drives the adjusting rod 12 to move to the right, and the suction cup part 2 is close to 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, the suction cup 21 is rotated so that the suction cup 21 is in a vertical upward state, and the suction cup 21 is adsorbed on the vehicle, and the outer ring 32 is released, and the spring 344 rebounds, pushing the convex rod 331 to move forward along the slide groove 342, and the convex rod 331 drives the push rod 332 to move forward synchronously, and no longer squeezes the convex ring 3434, and the first torsion spring in the connecting shaft 3432 rebounds, driving the clamping body 3431 to rotate, and the tip of the clamping body 3431 is inserted into the clamping groove 14, and the locking mechanism 3 is fixed on the adjusting rod 12, and the suction cup 2 is sucked. The disk 2 is also fixed on the adjustment rod 12 by the locking mechanism 3, preventing the adjustment rod 12 from rotating and maintaining 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 to extend, the pulling force of the pull rope 348 on the pull rod 3453 is reduced, and the second torsion spring in the connecting column 3454 rebounds, driving the locking body 3451 to rotate, so that the locking tip 3452 extends into the sharp groove inside the slot 14, further strengthening the connection strength between the locking mechanism 3 and the adjustment rod 12. When the vehicle shakes, the support 11 drives the antenna body 5 to rotate around the adjustment rod 12. Since the adjustment rod 12 is located above the center of gravity of the support 11, the support 11 slowly stops under the action of its own weight, and makes the end with the antenna body 5 installed face upward. The antenna body 5 is located directly above the center of gravity of the support 11, so when the support 11 is stationary, the antenna body 5 is vertically upward.

[0058] Example 2

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

[0060] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
