Specific embodiments

[0033] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0034] As Figure 1-4 shown, the present utility model discloses an automobile antenna base, comprising:

[0035] An antenna base 1, provided with a plurality of card slots 3 for installing an upper housing 2 around it, and a protruding portion 4 is provided on the lower surface. An installation groove 5 is provided on the front side of the protruding portion 4. The installation grooves 5 are symmetrically arranged, and a retaining strip 6 is provided in the installation groove 5; an installation hole 11 is also provided on the side surface of the protruding portion 4;

[0036] A mounting block 7, comprising a main body portion 71 and a bending portion 72. The main body portion 71 is provided with a fixing portion; the bending portion 72 is provided with an abutting surface 76 facing the antenna base 1. During installation, the main body portion 71 extends into the installation groove 5 for fixing, and the bending portion 72 abuts against the vehicle roof 8.

[0037] The advantage of adopting the above technical solution is to achieve rapid installation, ensure the installation efficiency and installation quality, and reduce abnormal noises.

[0038] In some embodiments, the main body portion 71 is provided with a hollowed-out portion 73, and the fixing portion is arranged within the hollowed-out portion 73. The fixing portion is an elastic piece 74 protruding outward. The elastic piece 74 is arranged along the length direction from one end of the main body portion 71 and protrudes outward as a whole towards the direction of the stop bar 6. An abutting portion 75 is arranged at the end of the elastic piece 74. During installation, the abutting portion 75 contacts the stop bar 6. The arrangement of the abutting portion 75 enables the elastic piece 74 to better contact the stop bar 6, ensuring stable installation, effectively preventing the installation block 7 from shaking, and reducing abnormal noises during driving.

[0039] In some embodiments (as Figure 5 shown), the close-fitting surface 76 is located in the middle of the bent portion 72. Both ends of the close-fitting surface 76 are bent downward. One end is connected to the main body portion 71, and the connection part with the main body portion 71 also has a bend, making the bent portion 72 reverse into an "N" shape. There is a certain elasticity between the bent portion 72 and the main body portion 71. During installation, the vehicle roof 8 is located between the close-fitting surface 76 and the antenna base 1, enabling the bent portion 72 to generate an upward pressing force on the vehicle roof 8, making the installation of the antenna base 1 and the vehicle roof 8 stable, effectively reducing abnormal noises, and facilitating installation at the same time.

[0040] In other embodiments (as Figure 6 shown), the close-fitting surface 76 is located at one end of the bent portion 72. The side surface of the close-fitting surface 76 is bent downward and then horizontally bent to be connected to the main body portion 71. The bent portion 72 forms an inverted "U" shape, and the close-fitting surface 76 is the side surface of the "U" shape. During installation, the close-fitting surface 76 also tightly adheres to the vehicle roof 8, increasing the elasticity of the entire bent portion 72, and at the same time increasing the contact area with the vehicle roof 8, reducing the local pressure on the vehicle roof 8, and can be applicable to the connection of vehicle roofs 8 with different thicknesses, expanding the scope of use.

[0041] In some embodiments, a connecting strip 61 is arranged on the side surface of the stop bar 6. A receiving portion 62 for accommodating the fixing portion is arranged within the connecting strip 61. The connecting strip 61 is also arranged within the hollowed-out portion 73 and is at a 90-degree angle to the stop bar 6, playing a connecting role, enhancing the strength of the stop bar 6, and ensuring that the stop bar 6 is not easily damaged.

[0042] The advantage of adopting the above technical solution is that the arrangement of the connecting strip 61 plays a fixing role, ensuring that the stop bar 6 is firm and not easily damaged. At the same time, the arrangement of the receiving portion 62 is used to limit the position of the elastic piece 74, enabling the elastic piece 74 to be easily installed in place.

[0043] Furthermore, the protruding portion 4 is provided with symmetrically arranged clamping blocks 9, and a plurality of reinforcing ribs 91 are arranged on the outer side of the clamping blocks 9.

[0044] The advantage of adopting the above technical solution is that the arrangement of the clamping blocks 9 is used to clamp other shells, and the arrangement of the reinforcing ribs 91 ensures the installation strength and extends the service life.

[0045] Further, the mounting block 7 is an integrally formed part.

[0046] The advantage of adopting the above technical solution is that the integrally formed part is convenient for processing and has a long service life.

[0047] In some embodiments, the antenna base 1 is further connected with a circuit board and an antenna body. The upper shell 2 is provided with a buckle for connecting with the antenna base 1. At the same time, a sealing ring is arranged inside the upper shell 2 to prevent water from entering. A plurality of fixing grooves 12 are arranged inside the antenna base 1 for installing the circuit board and the antenna body.

[0048] During the installation process, first, the mounting block 7 is installed on the antenna base 1. Then, one end of the antenna base 1 is inserted into the hole opened in the vehicle roof 8. At this time, it is limited by the protruding part 4, and the bending part 72 on the mounting block 7 is located on the lower side of the vehicle roof 8. Then, the antenna 1 base is pressed tightly against the vehicle roof 8. Bolts are installed in the mounting holes 11 to fix the other end of the antenna base 1. At this time, the mounting block 7 exerts an upward force on the vehicle roof 8, effectively reducing abnormal noise and facilitating installation.

[0049] For those of ordinary skill in the art, without departing from the creative concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
