Technical Field

[0001] The utility model relates to the field of automotive antennas, and specifically to an automotive antenna. Background Art

[0002] An automotive antenna is a device assembled on an automobile for receiving radio signals, mainly used for aspects such as broadcasting, television, and mobile communication. The working principle of an automotive antenna is based on capturing radio wave signals from the surrounding environment, such as radio stations, television transmission towers, and other radio wave sources, and through the oscillation and amplification of the antenna elements, transmitting the signals to in-vehicle devices for use.

[0003] The existing installation methods of automotive antennas are roughly divided into several types. Specifically, they are: edge-clamping type, suction cup type, adhesive type, and bolt installation type. For the bolt installation form, this method not only has flexible installation points but also can ensure a stable rigid connection with the automobile. Therefore, it occupies a large sales share in today's market. However, the exposed bolt structure affects the aesthetic appearance of the mounting bracket and the automobile to a certain extent, which also limits the target audience of antenna products. Therefore, there is an urgent need to design a new antenna installation structure that can cover fastening components such as bolts while maintaining the stable installation form of bolts, improving the aesthetic appearance and practicality of the antenna support frame. Summary of the Utility Model

[0004] Based on this, the purpose of the present utility model is to provide an automotive antenna to solve the technical problem that the exposed bolt structure affects the aesthetic appearance of the mounting bracket and the automobile, and this installation method affects the target audience of the antenna to a certain extent.

[0005] To achieve the above purpose, the present utility model provides the following technical solution: an automotive antenna, including a bottom plate, a cover plate, and an antenna. A clamping mechanism is arranged between the bottom plate and the cover plate. The clamping mechanism includes a clamping plate. An installation groove is opened inside the cover plate, and the clamping plate is clamped with the installation groove. Installation holes are opened on the surface of the bottom plate, and bolts are arranged inside the installation holes. The cover plate is used to cover the bolts.

[0006] By adopting the above technical solution, the cover plate covers the bottom plate and the bolts thereon, which can effectively prevent the bolts from being directly exposed to the external environment.

[0007] Further, the clamping plate has an "L" - shaped structure, and the clamping plate is fixedly connected to the bottom plate.

[0008] By adopting the above technical solution, the connection stability with the bottom plate is enhanced. Since the clamping plate is fixedly connected to the bottom plate, this structure enables the clamping plate to firmly support the cover plate during installation or disassembly, preventing it from shaking or shifting.

[0009] Furthermore, the bolt is used for threaded installation of the bottom plate and the vehicle. There are two installation holes, and the installation holes are counterbore structures.

[0010] By adopting the above technical solution, the stability and reliability of the antenna installation are ensured. Through threaded connection, the bolt can firmly fix the bottom plate on the vehicle, effectively preventing the antenna from moving or falling off due to vibration or external force.

[0011] Furthermore, a movable groove is formed on the surface of the clamping plate, and a spring piece is arranged inside the movable groove. The movable groove is used to provide a movable space for the spring piece.

[0012] By adopting the above technical solution, the movable groove provides a necessary movable space for the spring piece, enabling the spring piece to deform flexibly during the clamping and unclamping processes, thereby achieving a firm connection or convenient separation between the bottom plate and the cover plate.

[0013] Furthermore, a clamping block is arranged on one side of the top end of the spring piece, and a clamping groove is formed on one side of the inner wall of the installation groove. The clamping block is engaged with the clamping groove.

[0014] By adopting the above technical solution, the clamping block at the top end of the spring piece is engaged with the clamping groove on the inner wall of the installation groove, ensuring the connection firmness between the bottom plate and the cover plate. This clamping structure effectively prevents the bottom plate and the cover plate from accidentally separating due to vibration during driving, thus guaranteeing the stability of the antenna installation structure.

[0015] Furthermore, through holes are formed on the surface of the cover plate for disengaging the clamping block and the clamping groove.

[0016] By adopting the above technical solution, the through holes provide a convenient operation method for disengaging the clamping block and the clamping groove. Through the through holes, users can easily press the spring piece with tools to disengage the clamping block from the clamping groove, achieving a quick separation between the bottom plate and the cover plate.

[0017] Furthermore, two mounting ears are arranged on one side of the cover plate. An installation seat is arranged between the two mounting ears, and a movable ear is arranged on one side of the installation seat. The movable ear is detachably connected to the antenna.

[0018] By adopting the above technical solution, the two mounting ears provide a stable support structure for the installation of the antenna, and the installation seat and the movable ear between the mounting ears further enhance the installation firmness of the antenna.

[0019] Furthermore, the movable ear is rotatably connected to the mounting base, and the antenna has two (but not limited to two) forms of angle installation performance.

[0020] By adopting the above technical solution, the rotatable connection mode between the movable ear and the mounting base enables the antenna to freely adjust the angle within a certain range, providing greater flexibility for users. The angle of the antenna can be adjusted according to actual needs to obtain the best signal reception effect.

[0021] In summary, the main beneficial effects of the present utility model are as follows:

[0022] 1. Through the cover plate and the clamping mechanism, the present utility model uses the cover plate to shield the bottom plate and the bolts, effectively preventing the bolts from being directly exposed. This not only improves the protection effect of the bolts and extends their service life, but also significantly enhances the aesthetics of the antenna installation structure. At the same time, the beauty and practicality make the antenna more attractive, which can expand the audience group and thus enhance the commercial value of the antenna. In short, it not only protects the installation structure but also enhances the market competitiveness of the product, playing a positive role in promoting and selling the antenna.

[0023] 2. By setting the spring piece, the clamping block and the clamping groove, as the clamping plate slides inside the installation groove, the spring piece deforms under the abutment of the inner wall of the installation groove, which enhances the flexibility and self - adaptability of the clamping mechanism. When the position of the clamping block and the clamping groove is opposite, the elastic force of the spring piece is used to achieve clamping, ensuring the firm connection between the bottom plate and the cover plate, effectively preventing the bottom plate and the cover plate from falling off, greatly improving the stability of the antenna installation structure. At the same time, this stable clamping method also enhances the anti - theft performance of the antenna because it is difficult for non - professionals to easily release the clamping, thus protecting the antenna from the threat of theft.
