Description

Technical Field

[0001] The utility model belongs to but is not limited to the technical field of vehicle-mounted whip antennas, and in particular relates to a multi-angle shortwave blind-zone-free adjustable vehicle-mounted whip antenna lodging device. Background Art

[0002] Vehicle-mounted whip antennas are a key component in retrofitting communications vehicles. However, early-generation vehicles often installed fixed whip antennas. These require disassembly and reinstallation when navigating height-restricted environments like culverts, which is laborious and complex. Replacing these antennas is also expensive. For short-range communications, the whip antenna is often bent and positioned prone, utilizing the reflection effect of the vehicle roof to increase high-elevation-angle radiation and improve communication in blind spots.

[0003] Therefore, it is necessary to design a multi-angle shortwave blind-spot-free adjustable vehicle-mounted whip antenna lodging device. Utility Model Content

[0004] In response to the problems existing in the prior art, the utility model provides a low-cost, reliable and stable, simple to install and easy to use multi-angle shortwave blind-spot-free adjustable vehicle-mounted whip antenna lodging device.

[0005] The utility model is realized in this way: a multi-angle manually adjustable vehicle-mounted whip antenna retraction device comprises a retraction base, a retraction rod, and a locking device;

[0006] The lodging base is composed of a lower support rod and a lodging plate welded together, the lodging plate is in the shape of a large cut circle, a hinge hole is provided at the center of the lodging plate, and limiting holes are evenly distributed in a semicircle on the lodging plate; the lower support rod is movably connected to the lodging rod; a positioning shaft hole is provided at the lower end of the lodging rod, the positioning shaft passes through the positioning shaft hole at the lower end of the lodging rod and the hinge hole at the center of the lodging plate in sequence, the ball nut is installed into the threaded part of the positioning shaft, and tightened to complete the hinge;

[0007] The locking device is composed of a side nut, a pin with a pull ring and a spring. The spring pushes the pin with the pull ring to pass through the inverted plate to form a perforated pin connection.

[0008] Furthermore, before the inverted plate is welded to the lower support rod, a cylindrical pin is installed inside.

[0009] Furthermore, an internal thread is provided in the lower support rod, and fixing screws are provided on both sides. The internal thread can be screwed together with the external thread on the upper part of the non-fallover antenna base, and then reinforced by the fixing screws.

[0010] Furthermore, 7 limiting holes are evenly distributed in a semicircle on the inverted plate, with an interval of 30° between each hole. The front section of the whip antenna is fixed to the front of the vehicle at a 60° inversion. The whip antenna can be bent to achieve two polarization modes: horizontal polarization and vertical polarization.

[0011] In combination with the above technical solutions and the technical problems solved, the advantages and positive effects of the technical solutions to be protected by the present utility model are as follows:

[0012] First, the utility model provides a multi-angle manually adjustable vehicle-mounted whip antenna retraction device, which uses the original assembly holes of the antenna base and the vehicle body, without the need to drill new holes, avoiding water leakage caused by inappropriate vehicle body hole size or improper waterproofing.

[0013] The utility model provides a multi-angle manually adjustable vehicle-mounted whip antenna retraction device. After the lower support rod and the original antenna base are screwed together, tightening screws are installed on both sides. The retraction rod is fixedly connected once and the other side is movably connected. The movable part and the tail rod of the antenna rod can realize fixed-axis rotation, thereby realizing multi-angle adjustment under different conditions. The cylindrical pin is installed and the tightening screw is installed in advance, which greatly increases the reliability of the utility model.

[0014] The utility model provides a multi-angle manually adjustable vehicle-mounted whip antenna retracting device. The locking device consists of a side nut, a cylindrical pin with a pull ring, and a spring. The relative stillness of the retracting plate and the retracting rod is achieved through the compression of the spring, thereby achieving a fixed angle of the antenna rod. When the angle needs to be changed, it is only necessary to pull the pin to disengage the pin from the pin hole of the retracting plate, and the device can be easily rotated. The angle change can be completed by one person, which is easy and labor-saving, and the installation is simple and quick.

[0015] The utility model provides a multi-angle manually adjustable vehicle-mounted whip antenna tumbling device. By installing the whip antenna on this device and fixing the top of the tumbled antenna pole to the front bumper of the vehicle, the high-elevation-angle radiation component can be increased, the blind spot communication effect can be improved, and blind spot-free communication within a specific range can be achieved.

[0016] Second, the expected revenue and commercial value of this utility model after its technical solution is implemented are as follows: Since there are still a large number of old communication vehicles in use on the market, installing this device is inexpensive, quick, and convenient. The expected revenue is in the millions, and the potential commercial value is enormous.

[0017] The technical solution of this utility model fills the technical gap in the industry at home and abroad: in the past, antenna retraction devices mostly removed the original antenna base and used the existing improved device to achieve the retraction function. The original antenna base could not be reused, which wasted resources. This solution only needs to install an antenna retraction device between the original antenna base and the antenna pole, avoiding waste, realizing the transformation of old objects and product innovation.

[0018] The technical solution of this utility model solves a technical problem that people have long desired but have never been able to solve: the old antenna base of old communication vehicles cannot be lowered. When passing through height-restricted environments such as culverts, it needs to be disassembled and reinstalled, which is laborious and complicated. To achieve easy lowering, the only way to achieve it is to drill holes again and replace the antenna base with a lowering device to lower the vehicle-mounted whip antenna. However, this solution can achieve the lowering of the vehicle-mounted whip antenna by installing this device without changing the hole position. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] like Figure 1 As shown, the present invention provides a multi-angle manually adjustable vehicle-mounted whip antenna retraction device, comprising a retraction base, a retraction rod 5, and a locking device. The retraction base and retraction rod 5 are hingedly connected on one side by a positioning shaft 4. The retraction rod 5 is movably connected on the other side, allowing it to be rotated to different angles and then locked by the locking device for use with the original antenna base. The original antenna base is bolted to the vehicle body using the mounting holes on the top of the vehicle body.

[0027] The lodging base is composed of a lower support rod 3 welded to a lodging plate 2; the lodging plate 2 is in the shape of a large cut circle, with a hinge hole 21 at the center of the lodging plate 2, and 7 limit holes 22 evenly distributed on the upper semicircle of the lodging plate 2, with an interval of 30° between each hole, to achieve multiple states. Among them, the front section of the whip antenna is fixed to the front of the vehicle at a 60° angle of retraction, and the whip antenna can be bent to achieve horizontal polarization and vertical polarization. The reflection effect of the roof is used to increase the high-elevation-angle radiation component, thereby improving the blind spot communication effect and solving the shortwave blind spot-free communication problem.

[0028] The locking device includes a side nut 6 screwed on the falling rod 5, a pin 7 with a pull ring 12 passing through the side nut, a spring 8 passing through the small hole end of the pin 7, a positioning shaft 4 passing through the falling plate 2 and the falling rod 5, and a ball nut 10 screwed on the external threaded end of the positioning shaft 4. The spring 8 is used to push the pin 7 with the pull ring 12 through the falling plate 2 to form a through-hole pin connection.

[0029] The entire body of this utility model is made of 304 stainless steel. The falling plate 2 is welded to the lower support rod 3, and a cylindrical pin 9 is installed inside before welding. The lower support rod 3 is provided with an internal thread, and there are tightening screws 11 on both sides. The internal thread can be tightened with the external thread on the upper part of the non-falling antenna base, and then reinforced by the tightening screws 11.

[0030] After the cam 18 is released, the pin 7 can pass through the limiting hole 22 on the reversing plate 2 of the reversing base to achieve fixation, and finally achieve fixation at multiple angles.

[0031] The utility model has a multi-angle manually adjustable vehicle-mounted whip antenna retraction device, which realizes the stable retraction of the antenna at different angles through the combination of the retraction base, the retraction rod, and the locking device, and can adjust the antenna angle according to different needs. First, the retraction base is welded by the lower support rod and the retraction plate. The retraction plate is in the shape of a large circle, with a hinge hole at the center of the circle. The retraction base is hinged to one side of the retraction rod through the positioning axis, allowing the retraction rod to rotate within a certain range, thereby realizing the angle adjustment of the antenna. There are 7 limiting holes distributed in the upper semicircle of the retraction plate, and the interval between each hole is 30°, which realizes a variety of angle adjustments in the range of 0° to 180°, adapting to different communication needs.

[0032] The other end of the reversing rod is flexibly connected to the reversing plate for angle adjustment. When the reversing rod is rotated to the desired angle, a locking device secures the rod, ensuring the antenna is securely positioned at the desired angle. The locking device is connected to a pin via a side nut. The pin passes through a selected stop hole in the reversing plate. A spring pushes the pin through the hole, where it is locked by a ball nut, securing the reversing rod and reversing plate at the preset angle. This design ensures that the reversing rod does not loosen during use, maintaining the stability and reliability of the antenna.

[0033] In addition, during the actual installation, the original antenna base is matched with the assembly holes on the top of the vehicle body, and the original antenna base is fixed to the vehicle body with bolts. The inverted base is fixed to the top of the vehicle body through the positioning axis and the original antenna base, ensuring that the structure of the entire inverted device is stable and tightly integrated with the vehicle body to avoid loosening or falling off during driving. At the same time, the inverted pole can be pulled to a 60° inverted state, fixing the front section of the antenna to the front of the vehicle. By adjusting the bending of the antenna, a dual-polarization mode of horizontal polarization and vertical polarization can be achieved. This design utilizes the reflective characteristics of the roof to effectively increase the high-elevation-angle radiation component, improve the blind spot problem of shortwave communication, and achieve blind-spot-free communication.

[0034] Finally, the locking and adjustment functions of the whip antenna's tilting mechanism are simple manual operations, requiring no additional tools. A spring pushes a pin through the tilting plate hole and the tilting rod's positioning axis, enabling quick manual adjustment and locking. This allows users to manually adjust the antenna angle and maintain stability for varying communication needs.
