It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0031] To address the technical problem that the large windward area of ​​a circular radome can easily lead to significant wind resistance, this invention provides a vehicle-mounted mobile satellite antenna that can reduce wind resistance and improve the stability of the vehicle-mounted mobile satellite antenna.

[0032] Please see Figure 1-6This utility model provides a vehicle-mounted satellite communication antenna for vehicle communication. The vehicle-mounted satellite communication antenna includes a chassis 1 and an antenna cover 2. The satellite antenna body 101 is mounted on the chassis 1. The antenna cover 2 includes a circular shell portion 21 and a pointed tail portion 22 arranged sequentially along the vehicle's driving direction. The pointed tail portion 22 is connected to one side of the circular shell portion 21. The two sides of the pointed tail portion 22 converge into a pointed tip in the direction away from the circular shell portion 21, forming a teardrop-shaped outer peripheral curved surface with the circular shell portion 21, thereby reducing the... The wind resistance of the entire radome 2 is reduced by the circular shell portion 21 covering the chassis 1, with an arc-shaped transition surface at its front end to the top surface. The top surface of the pointed tail portion 22 is inclined towards the ground in a direction away from the circular shell portion 21. The circular shell portion 21 covers the chassis 1, and an arc-shaped transition surface 2101 is formed on the side of the circular shell portion 21 away from the pointed tail portion 22, which connects to the top surface of the circular shell portion 21, so that the pointed tail portion 22 and the circular shell portion 21 form a teardrop-shaped structure, further reducing wind resistance.

[0033] In this embodiment, the chassis 1 is disc-shaped, with at least four bolt mounting ears 102 on its outer periphery. The chassis 1 retains the conventional disc shape and has at least four multi-point fixings, reducing the cost of modification and providing a certain degree of stability when installed on the vehicle body. The circular shell part 21 is placed on the chassis 1, and together with the pointed tail part 22, a teardrop-shaped streamline is formed in the top view, which can effectively reduce wind resistance. Furthermore, the arc transition surface 2101 and the inclined surface 2102 form a streamline shape in the front view, further reducing wind resistance.

[0034] In one embodiment, please refer to Figure 4 In order to enable quick assembly and disassembly of the chassis 1 and the radome 2 after the addition of the pointed tail 22, a nesting component 3 and a locking component 4 are provided between the chassis 1 and the radome 2, respectively located at the front and rear ends of the radome 2, for fastening the radome 2 and the chassis 1. The nesting component 3 fits the front end of the radome 2 onto the front end of the chassis 1 for positioning, and then covers the rear end of the chassis 1 with the radome 2 and locks it with the locking component 4, thereby achieving the purpose of quick assembly and disassembly.

[0035] Specifically, the nested component 3 includes an insert plate 31 and a limiting block 32. The insert plate 31 is fixedly connected to the bottom front end of the circular shell portion 21 and has the same curve as the outer curved surface of the circular shell portion 21. The limiting block 32 is fixedly connected to the side of the insert plate 31 near the chassis 1. The front end of the chassis 1 has an open groove 103 that communicates with the bottom of the chassis 1. A limiting groove 104 is formed at the bottom of the open groove 103. The insert plate 31 is inserted into the open groove 103. Next, the limiting block 32 is inserted into the limiting groove 104 and abuts against the inner top wall of the limiting groove 104. First, the insert plate 31 and the limiting block 32 are moved down, and the limiting block 32 is inserted into the limiting groove 104. Then, the antenna cover 2 is covered onto the chassis 1, and the insert plate 31 is inserted into the open groove 103. Through the insertion of the limiting block 32 into the limiting groove 104 and the insert plate 31 into the open groove 103, the front end is fitted and positioned. After fitting, the antenna cover 2 is also covered onto the chassis 1 and initially positioned.

[0036] Furthermore, the locking assembly 4 includes an extension frame 41 and a locking bolt 42. The extension frame 41 is fixedly connected to the tail end of the chassis 1. The top of the pointed tail portion 22 is provided with a mounting hole 2202. The extension frame 41 is provided with a screw hole 4101 that aligns with the mounting hole 2202. The locking bolt 42 passes through the mounting hole 2202 and is threadedly connected to the screw hole 4101. When the radome 2 is closed and initially positioned on the chassis 1, the pointed tail portion 22 closes onto the extension frame 41 and aligns the mounting hole 2202 with the screw hole 4101. At this time, the locking bolt 42 is installed to secure the connection between the radome 2 and the chassis 1, which is convenient to operate.

[0037] Furthermore, to prevent the locking bolt 42 from protruding above the inclined surface 2102, the locking bolt 42 is embedded inside the mounting hole 2202.

[0038] Furthermore, in order to prevent water from accumulating in the mounting hole 2202, the locking assembly 4 also includes a rubber plug 43, which is inserted into the mounting hole 2202.

[0039] Furthermore, in order to avoid the concavity affecting the streamline of the inclined surface 2102, the upper surface of the rubber stopper 43 is flush with the inclined surface 2102.

[0040] Furthermore, to facilitate manual assembly and disassembly, the locking bolt 42 includes a screw 421 and a hand-rotating part 422. The screw 421 is fixedly connected to the bottom of the hand-rotating part 422, and the top of the hand-rotating part 422 has two semi-circular grooves 423, which make it easy for fingers to grip and rotate the locking bolt 42.

[0041] In one embodiment, please refer to Figure 5 and Figure 6 In order to protect the plug from rainwater corrosion, the rear end of the chassis 1 is provided with a plug socket 105. The bottom of the pointed tail 22 is provided with an inner groove 2201. The plug socket 105 is inserted into the inner groove 2201. The pointed tail 22 forms a shield on the plug, thus forming protection for the data cable end connection.

[0042] Furthermore, the extension bracket 41 is fixed on the plug socket 105 and inserted into the inner groove 2201, making reasonable use of space.

[0043] To better understand this utility model, the following is combined with... Figures 1 to 6 The technical solution of this utility model is described in detail as follows: The antenna cover 2 is based on the circular shell part 21 with the addition of a pointed tail part 22, forming a teardrop shape with low wind resistance. The wind resistance is further reduced on the circular shell part 21 and the pointed tail part 22 by the arc transition surface 2101 and the inclined surface 2102, so that the wind resistance of the entire vehicle-mounted mobile satellite antenna is lower and more stable than that of the circular antenna cover. During installation, the limiting block 32 is first inserted into the limiting groove 104, the insert plate 31 is inserted into the open groove 103, and then the locking bolt 42 and the rubber plug 43 are installed. Disassembly and assembly are performed by reversing the above operations, which is convenient for disassembly and assembly.

[0044] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
