Description

Technical Field

[0001] This utility model relates to the field of vehicle antenna technology, and in particular to an integrated folding antenna for vehicle terminals. Background Technology

[0002] An antenna is a device used to transmit and receive electromagnetic waves. It plays a vital role in wireless communication, broadcasting, television, radar, and navigation. The integrated foldable antenna for vehicle terminals is an antenna specifically designed for vehicle communication equipment. It integrates multiple antenna functions and has a foldable feature to meet the usage needs of vehicles in different scenarios.

[0003] Current antenna technology involves mounting an integrated folding antenna body onto a base and securing it with screws to prevent shaking or loosening during use. However, vehicles vibrate continuously during operation, and prolonged vibration can cause the screws securing the antenna to gradually loosen. Once the screws loosen, the antenna will wobble, affecting the stability of signal reception. Existing technology uses anti-loosening washers, which consist of two washers: an inner washer with serrations and an outer washer that is smoother. When the screw is tightened, the serrated inner washer embeds itself between the screw and the fastened component, increasing friction and preventing loosening. However, after repeated disassembly and installation, the serrations of the anti-loosening washer wear down, reducing its embedding ability and friction-increasing effect. This gradually diminishes its anti-loosening performance, causing the secured antenna to loosen and hindering subsequent information reception and transmission. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an integrated folding antenna for vehicle terminals, which aims to improve the problem that in the prior art, after repeated disassembly and installation, the teeth of the serrated inner washer will wear down, causing the anti-loosening performance to gradually decrease and leading to the problem of the installed and fixed antenna becoming loose.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an integrated folding antenna for a vehicle-mounted terminal, comprising a base, a circular ring fixedly connected to the bottom of the inner wall of the base, a central inner sliding groove ring rotatably connected to the top of the circular ring, multiple arc-shaped plates rotatably connected at equal intervals around the inner wall of the central inner sliding groove ring, semi-circular blocks fixedly connected to adjacent sides of the outer wall of each arc-shaped plate, multiple fixed short posts rotatably connected at equal intervals to the top of the circular ring, the top of each fixed short post being fixedly connected to a semi-circular block, a fixed short plate fixedly connected to the inner bottom wall of the base, a threaded rod rotatably connected to the middle of the outer wall of the fixed short plate, a movable plate threadedly connected to the outer wall of the threaded rod, the right side of the outer wall of the movable plate being fixedly connected to the outer wall of the central inner sliding groove ring, a hollow inner sliding plate fixedly connected to the front side of the inner wall of the base, a receiving antenna installed inside the base, and a protective mechanism installed on the top of the base, the protective mechanism being used to cover and protect the rotating connection of the receiving antenna.

[0006] As a further description of the above technical solution:

[0007] The protective mechanism includes a hollow circular block, which is installed on the top of the base. Multiple tension springs are fixedly connected at equal intervals to the bottom end of the hollow circular block. A telescopic sleeve is fixedly connected to the other end of the outer wall of each tension spring. An L-shaped support plate is fixedly connected to the front side of the outer wall of the receiving antenna. A fixed column is rotatably connected to the front side of the outer wall of the L-shaped support plate. A coiled rope is fixedly connected to the outer wall of the fixed column. The other end of the outer wall of the coiled rope is fixedly connected to the outer wall of the telescopic sleeve. A spring column is installed on the top of the L-shaped support plate.

[0008] As a further description of the above technical solution:

[0009] A screw is threadedly connected to the top right side of the base, and a warning sign is threadedly connected to the outer wall of the screw.

[0010] As a further description of the above technical solution:

[0011] A hollow box is fixedly connected to the bottom front side of the base, and a drawer is slidably connected inside the hollow box.

[0012] As a further description of the above technical solution:

[0013] A handle is fixedly connected to the front side of the outer wall of the drawer, and a protective sleeve is fixedly connected to the outer wall of the handle.

[0014] As a further description of the above technical solution:

[0015] A circular throttle handle is fixedly connected to the right end of the outer wall of the threaded rod, and an anti-slip sleeve is fixedly connected to the outer wall of the circular throttle handle.

[0016] As a further description of the above technical solution:

[0017] A circular throttle is fixedly connected to the front end of the outer wall of the fixed column, and a protective sleeve is fixedly connected to the outer wall of the circular throttle.

[0018] As a further description of the above technical solution:

[0019] The top of the spring column is threaded with a screw two, and the outer wall of the screw two is threaded with a protective sleeve one.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the moving plate on the outer wall is driven to move by rotating the threaded rod. The movement of the moving plate causes the inner sliding groove ring in the center to move to the right synchronously, thereby causing the semi-circular blocks on multiple arc plates to rotate and move closer to the receiving antenna, thus achieving clamping and fixing of the receiving antenna. This avoids the problem that the teeth of the serrated inner washer will wear down after repeated disassembly and installation, causing the anti-loosening performance to gradually decrease and leading to the problem of the fixed antenna becoming loose.

[0022] 2. In this utility model, by pulling the spring column to disengage it from the groove of the fixing column, and rotating the fixing column to rewind the rope, the sleeve extends downward to cover the rotating connection of the receiving antenna for protection. Then, the pulled spring column is released so that its bottom engages with the groove of the fixing column for fixation. This avoids the problem of damage to the receiving antenna due to prolonged use and erosion by external rainwater at the rotating connection of the receiving antenna. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 4 and Figure 5This utility model provides an embodiment of an integrated folding antenna for a vehicle-mounted terminal, comprising a base 1. A circular ring 23 is fixedly connected to the bottom of the inner wall of the base 1. A circular inner groove ring 20 is rotatably connected to the top of the circular ring 23. Multiple arc-shaped plates 18 are rotatably connected at equal intervals around the inner wall of the circular inner groove ring 20. Semi-circular blocks 17 are fixedly connected to adjacent sides of the outer wall of each arc-shaped plate 18. Multiple fixed short posts 24 are rotatably connected at equal intervals to the top of the circular ring 23. The fixed short posts 24 serve to fix and support the circular ring 23 for rotational clamping. The top of the fixed short posts 24 is fixedly connected to the semi-circular blocks 17. A fixed short plate 21 is fixedly connected to the inner bottom wall of the base 1. A threaded rod 5 is rotatably connected to the middle of the outer wall of the fixed short plate 21. A movable plate 19 is threadedly connected to the outer wall of the threaded rod 5. The right side of the outer wall of the movable plate 19 is connected to the outer wall of the circular inner groove ring 20. The base 1 is fixedly connected to a hollow inner sliding plate 22. A receiving antenna 16 is installed inside the base 1. A protective mechanism 2 is installed on the top of the base 1 to protect the rotating connection of the receiving antenna 16. A screw 4 is threadedly connected to the top right of the base 1. A warning sign 3 is threadedly connected to the outer wall of the screw 4. The warning sign 3 can serve as a warning to the surrounding staff and the surrounding public to reduce the probability of device damage. A hollow box 11 is fixedly connected to the bottom front of the base 1. A drawer 12 is slidably connected inside the hollow box 11. The drawer 12 can be used to store tools for daily use and maintenance for future use.

[0033] Specifically, by rotating the threaded rod 5, since the threaded rod 5 is threadedly connected to the moving plate 19, and the moving plate 19 is guided and limited by the hollow inner slider plate 22, the moving plate 19 can only move in a specific direction. As the threaded rod 5 rotates, the moving plate 19 moves to the right, thereby driving the inner circular groove ring 20 fixedly connected to it to move to the right synchronously. When the inner circular groove ring 20 moves to the right, the semi-circular blocks 17 fixed on the multiple arc-shaped plates 18 equidistantly rotatably connected around its inner wall can rotate by relying on the fixed short column 24, and then through multiple arc... The semi-circular blocks 17 on the plate 18 gradually approach the receiving antenna 16 from different directions, eventually clamping and fixing the receiving antenna 16. A screw 4 is threadedly connected to the top right side of the base 1, and a warning sign 3 is threadedly connected to the outer wall of the screw 4. The warning sign 3 can serve as a warning to the surrounding staff and the surrounding public to reduce the probability of device damage. A hollow box 11 is fixedly connected to the bottom front side of the base 1. A drawer 12 is slidably connected inside the hollow box 11. The drawer 12 can facilitate the storage of tools for daily use and maintenance for future use.

[0034] Reference Figure 2 , Figure 3 and Figure 6 The protective mechanism 2 includes a hollow circular block 201, which is installed on the top of the base 1. Multiple tension springs 202 are fixedly connected at equal intervals to the bottom end of the hollow circular block 201. A telescopic sleeve 203 is fixedly connected to the other end of the outer wall of each tension spring 202. An L-shaped support plate 206 is fixedly connected to the front side of the outer wall of the receiving antenna 16. A fixing post 205 is rotatably connected to the front side of the outer wall of the L-shaped support plate 206. A coiled rope 207 is fixedly connected to the outer wall of the fixing post 205. Rotating the fixing post 205 causes the coiled rope 207 on the outer wall to retract, thereby pulling the fixing post 205 to rotate the receiving antenna 16. The area is covered for protection. The other end of the outer wall of the spiral rope 207 is fixedly connected to the outer wall of the telescopic sleeve 203. A spring column 204 is installed on the top of the L-shaped support plate 206. A handle 14 is fixedly connected to the front side of the outer wall of the drawer box 12. The handle 14 makes it easy for the staff to open or close the drawer box 12. A protective sleeve 2 13 is fixedly connected to the outer wall of the handle 14. A circular handle 2 15 is fixedly connected to the right end of the outer wall of the threaded rod 5. The circular handle 2 15 makes it easy for the staff to rotate the threaded rod 5. An anti-slip sleeve 6 is fixedly connected to the outer wall of the circular handle 2 15.

[0035] Specifically, by pulling the spring post 204, the bottom of the spring post 204 separates from the groove on the outer wall of the rotating fixed post 205. Then, the rotating fixed post 205 drives the coiled rope 207 fixed on the outer wall to wind up. Since the other end of the coiled rope 207 is connected to the telescopic sleeve 203, when the coiled rope 207 is wound up, it will pull the telescopic sleeve 203 connected to it, causing the telescopic sleeve 203 to extend downward to cover and protect the rotating connection of the receiving antenna 16. Finally, the pulled spring post 204 is released to allow the spring post to wind up. The bottom of the spring post 204 engages with the groove on the fixing post 205 to achieve fixation. A handle 14 is fixedly connected to the front side of the outer wall of the drawer box 12. The handle 14 makes it easy for the staff to open or close the drawer box 12. A protective sleeve 13 is fixedly connected to the outer wall of the handle 14. A circular handle 15 is fixedly connected to the right end of the outer wall of the threaded rod 5. The circular handle 15 makes it easy for the staff to rotate the threaded rod 5. An anti-slip sleeve 6 is fixedly connected to the outer wall of the circular handle 15.

[0036] Reference Figure 1 , Figure 2 and Figure 3A circular handle 9 is fixedly connected to the right end of the outer wall of the threaded rod 5. The circular handle 9 facilitates the operation of the threaded rod 5 by the operator. A protective sleeve 10 is fixedly connected to the outer wall of the circular handle 9. A screw 7 is threadedly connected to the top of the spring column 204. A protective sleeve 8 is threadedly connected to the outer wall of the screw 7. The protective sleeve 8 enhances the operator's comfort when pulling the protective sleeve 8 and prevents the slippage of the hand.

[0037] Specifically, a circular handle 9 is fixedly connected to the right end of the outer wall of the threaded rod 5. The circular handle 9 facilitates the operation of the threaded rod 5 by the operator. A protective sleeve 10 is fixedly connected to the outer wall of the circular handle 19. A screw 7 is threadedly connected to the top of the spring column 204. A protective sleeve 8 is threadedly connected to the outer wall of the screw 7. The protective sleeve 8 enhances the operator's comfort when pulling the protective sleeve 18 and prevents the slippage of the hand.

[0038] Working principle: By rotating the threaded rod 5, since the threaded rod 5 is threadedly connected to the moving plate 19, and the moving plate 19 is guided and limited by the hollow inner slider plate 22, the moving plate 19 can only move in a specific direction. As the threaded rod 5 rotates, the moving plate 19 moves to the right, which in turn drives the inner sliding ring 20 fixed to it to move to the right in sync. When the inner sliding ring 20 moves to the right, the semi-circular blocks 17 fixed on the multiple arc plates 18 that are equidistantly connected around its inner wall can rotate by relying on the fixed short column 24. Then, the semi-circular blocks 17 on the multiple arc plates 18 gradually approach the receiving antenna 16 from different directions, and finally achieve the clamping and fixing of the receiving antenna 16. This avoids the problem that the teeth of the serrated inner washer will wear down after multiple disassemblies and installations, which will gradually reduce the anti-loosening performance and cause the fixed antenna to loosen.

[0039] By pulling the spring post 204, the bottom of the spring post 204 is separated from the groove on the outer wall of the rotating fixed post 205. Then, the rotating fixed post 205 drives the coiled rope 207 fixed on the outer wall to wind up. Since the other end of the coiled rope 207 is connected to the telescopic sleeve 203, when the coiled rope 207 is wound up, it will pull the telescopic sleeve 203 connected to it, so that the telescopic sleeve 203 extends downward to cover and protect the rotating connection of the receiving antenna 16. Finally, the pulled spring post 204 is released so that the bottom of the spring post 204 engages with the groove on the fixed post 205 to achieve fixation, thereby avoiding the problem of damage to the receiving antenna 16 due to long-term use and external rainwater corrosion at the rotating connection of the receiving antenna 16.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
