Description

Technical Field

[0001] This utility model belongs to the field of vehicle communication equipment technology, specifically referring to a vehicle antenna that can be quickly replaced. Background Technology

[0002] Vehicle-mounted antennas are devices used to receive and transmit high-frequency radio waves. Their main functions include enhancing signals for navigation, radio, and 4G / 5G networks. They also provide additional benefits such as electrostatic discharge and aerodynamic optimization. Vehicle-mounted antennas need to be replaced or maintained periodically depending on the usage scenario and signal requirements. Traditional vehicle-mounted antenna installations have some drawbacks, such as:

[0003] 1. The installation and fixing structure is complex, often using multiple sets of bolts or adhesive bonding, and disassembly and replacement are time-consuming and labor-intensive.

[0004] 2. It is not easy to calibrate during installation, and deviations are prone to occur, affecting the use of the antenna.

[0005] To address this issue, a vehicle-mounted antenna that can be quickly replaced is proposed. Utility Model Content

[0006] The technical problem this invention aims to solve is that traditional vehicle-mounted antenna replacement operations are cumbersome, and calibration during installation is difficult, easily leading to deviations that affect antenna performance.

[0007] To achieve the above functions, the technical solution adopted by this utility model is as follows: a vehicle antenna that can be quickly replaced includes a mounting plate and a quick-release shell that is snapped onto the upper end of the mounting plate. An antenna is inserted into the upper end of the quick-release shell. A guide component for guiding the fit is provided between the mounting plate and the quick-release shell. A threaded groove is provided on the quick-release shell, and a bolt is threaded onto the threaded groove. The antenna is inserted into the bolt and is limited and rotated with it. A fixing component that cooperates with the bolt to achieve fixation is fixedly provided on the mounting plate.

[0008] Furthermore, the fixing component includes a reserved groove on the mounting plate that coincides with the threaded groove, and a base is fixedly installed in the groove. The bolt has a cylindrical groove and a frustum groove that are interconnected. A fixing shaft is fixedly connected to the inner wall of the end of the cylindrical groove, and the lower end of the fixing shaft extends into the interior of the base.

[0009] Furthermore, the base is provided with an array of multiple inclined bars. When the upper ends of the multiple inclined bars are squeezed together by the frustum groove, they form a frustum-shaped structure and clamp and fix the fixed shaft.

[0010] Furthermore, an annular block is fixedly connected to the lower end of the quick-release housing, and an annular groove adapted to the annular block is provided on the upper end of the mounting plate.

[0011] Furthermore, the annular block is made of magnetic material, and the inside of the annular groove is coated with a metal coating.

[0012] Furthermore, the antenna and the bolt are connected by a friction-damped rotating structure.

[0013] The beneficial effects of this utility model by adopting the above structure are as follows:

[0014] 1. Precise positioning and magnetic pre-fixing through the ring block and ring groove of the guide component, combined with the quick locking / unlocking of bolts and fixing components, eliminates the need for complicated tools, greatly improving antenna replacement efficiency and avoiding tedious operations;

[0015] 2. The oblique bars of the fixing component gather and clamp together with the spherical protrusions to form a double fixation. Combined with the magnetic adsorption of the guide component, it enhances the overall structural stability, effectively resists vehicle vibration, and ensures stable signal reception.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example 1:

[0024] like Figures 1 to 4 As shown, in order to achieve the above functions, the technical solution adopted by this utility model is as follows: a vehicle antenna that can be quickly replaced includes a mounting plate 1, a quick-release shell 2 is snapped onto the upper end of the mounting plate 1, an antenna 3 is inserted into the upper end of the quick-release shell 2, a guide component is provided between the mounting plate 1 and the quick-release shell 2, a threaded groove 8 is provided on the quick-release shell 2, a bolt 7 is threadedly connected to the threaded groove 8, the antenna 3 is inserted into the bolt 7 and is limited and rotatedly connected to it, and a fixing component is fixedly provided on the mounting plate 1.

[0025] like Figures 1 to 4 As shown, the fixing assembly includes a reserved slot on the mounting plate 1 that coincides with the threaded slot 8. A base 6 is fixedly installed in the slot. A cylindrical slot 9 and a frustum slot 10 that are interconnected are opened on the bolt 7. A fixing shaft 11 is fixedly connected to the inner wall of the end of the cylindrical slot 9. The lower end of the fixing shaft 11 extends into the interior of the base 6. Multiple inclined bars 14 are arranged in an array on the base 6. A limit slot 12 is opened on the fixing shaft 11. A spherical protrusion 13 is fixedly installed on the inner wall of the upper end of the inclined bar 14. The antenna 3 and the bolt 7 are connected by a friction damping rotation structure.

[0026] After the operator aligns the annular block 4 of the quick-release housing 2, they tighten the bolt 7, causing the fixing shaft 11 to extend into the base 6. The frustum groove 10 presses the upper end of the inclined strip 14 together, and the spherical protrusion 13 is engaged in the limiting groove 12 of the fixing shaft 11, thus completing the fixation. At this time, the antenna 3 can be rotated through the friction damping structure to adjust to a suitable receiving angle. When the antenna needs to be replaced, the bolt 7 is tightened in the opposite direction, the inclined strip 14 springs back, and the spherical protrusion 13 disengages from the limiting groove 12. The quick-release housing 2 can then be removed for replacement. The operation is convenient and efficient.

[0027] Example 2:

[0028] Based on Example 1, such as Figures 1 to 4 As shown, the guide assembly includes an annular block 4 fixed to the lower end of the quick-release housing 2. The upper end of the mounting plate 1 has an annular groove 5 that matches the annular block 4. The annular block 4 is made of magnetic material, and the annular groove 5 is coated with a metal coating. The annular groove 5 guides the annular block 4 of the quick-release housing 2, which facilitates subsequent installation.
