Description

Technical Field

[0001] This utility model relates to the field of vehicle antenna technology, and in particular to an installation and fixing structure and a vehicle antenna. Background Technology

[0002] As an indispensable component of modern vehicles, vehicle antennas undertake many critical tasks such as receiving broadcast, television, satellite navigation, mobile communication networks, and dedicated wireless communication signals. The stability of their performance directly affects the reliability of in-vehicle entertainment systems, navigation and positioning accuracy, and remote information processing.

[0003] Existing vehicle antenna mounting solutions commonly employ threaded connections, strong magnetic adsorption, or adhesive bonding. Threaded connections typically require pre-embedded or drilled threaded holes in the vehicle body. During installation, the antenna's threaded portion must be screwed in and tightened with tools. While this method offers high connection strength, the installation process is cumbersome, requires sufficient installation space, and may loosen under prolonged vibration, leading to unstable signal reception or even abnormal noise. Disassembly and maintenance also require tools, making it inconvenient. Magnetic adsorption is convenient, but its connection strength is limited, making it prone to displacement or detachment at high speeds or in harsh road conditions, posing safety hazards. Furthermore, the magnet may cause electromagnetic interference to the antenna's internal precision electronic components. Adhesive bonding suffers from long initial curing times, adhesion strength highly dependent on ambient temperature and humidity, and difficulty in cleaning residual adhesive after removal, potentially damaging the vehicle paint. These issues result in lower connection strength and installation convenience.

[0004] Therefore, in order to address the above problems, the applicant needs to design an installation and fixing structure and a vehicle-mounted antenna to solve the problem. Utility Model Content

[0005] On one hand, this application provides an installation and fixing structure, including a fixing plate, and a spring piece is fixedly disposed below the fixing plate.

The conical block is locked and connected to an external fixing object through the locking surface. A connecting rod is fixedly disposed above the fixing plate, and a sliding groove is disposed on the inner side of the connecting rod. A return spring is fixedly disposed on the inner side of the sliding groove, and a slider is fixedly disposed at one end of the return spring.

[0006] Preferably, the slider is provided with an inclined surface, which allows the slider to slide into the positioning more smoothly during installation and reduces installation resistance.

[0007] Preferably, multiple spring clips are provided and evenly distributed along the circumference of the fixing plate, providing a balanced clamping force and ensuring the stable fixing of the fixing plate.

[0017] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0018] Please refer to Figures 1-3 This utility model provides an installation and fixing structure, including a fixing plate 20, with a spring piece 21 fixedly disposed below the fixing plate 20. A conical block 22 is fixedly disposed on the outer surface of the spring piece 21, and a locking surface 23 is formed at the connection between the conical block 22 and the spring piece 21. The conical block 22 is locked and connected to an external fixing object through the locking surface 23. A connecting rod 24 is fixedly disposed above the fixing plate 20, and a sliding groove 240 is disposed on the inner side of the connecting rod 24. A return spring 241 is fixedly disposed on the inner side of the sliding groove 240, and a slider 242 is fixedly disposed at one end of the return spring 241. The end of the slider 242 away from the connecting rod 24 extends out of the end of the connecting rod 24. The cooperation between the spring piece 21 and the conical block 22 realizes the quick self-locking fixation of the lower part, and the spring-driven slider 242 realizes the automatic locking of the upper part. Together, they form an installation solution that does not require tools, is easy to operate, and has a stable connection, effectively overcoming the shortcomings of traditional threaded connections being cumbersome and magnetic adsorption being weak.

[0019] To allow the slider 242 to slide into position more smoothly during installation, the slider 242 is provided with an inclined surface 243.

[0020] like Figure 2 As shown, multiple spring pieces 21 are provided and evenly distributed along the circumference of the fixed plate 20. The material of the spring pieces 21 is spring steel. Multiple high-elasticity spring steel spring pieces 21 provide a balanced clamping force, ensuring the stable fixation of the fixed plate 20.

[0021] Please refer to Figure 4On the other hand, this application also provides a vehicle-mounted antenna with a mounting and fixing structure, including a mounting base 1, and a mounting hole 13 is provided on the mounting base 1. The mounting hole 13 cooperates with the fixing plate 20 and the slider 242 in the mounting and fixing mechanism to engage and connect the mounting base 1 and the mounting and fixing mechanism. A connector 10 is provided on the top of the mounting base 1, and an extension line 11 is provided inside the connector 10. A receiver head 12 is provided at the end of the extension line 11 away from the connector 10, and the receiver head 12 is used to receive external signals. This enables a quick and non-destructive engagement connection between the antenna body and the fixing base, greatly simplifying the antenna assembly and disassembly process, facilitating daily maintenance or replacement, and ensuring the stability of the electrical connection.

[0022] The mounting base 1 houses a signal processor, which is connected to a connecting cable 15. A connector 16 is located at the end of the connecting cable 15 furthest from the signal processor, and the connector 16 is electrically connected to the vehicle controller. A protective shell 14 is provided on the outside of the connecting cable 15, and the protective shell 14 is integrally connected to the mounting base 1. The radio frequency signal captured by the antenna receiver 12 is transmitted to the signal processor inside the mounting base 1 through the extension cable 11. The signal processor performs optimization processing such as amplification, filtering, or demodulation on the original signal, and then transmits it to the vehicle controller through the connecting cable 15 and the standardized connector 16 for use by in-vehicle entertainment, navigation, and other systems.

[0023] In summary, during use and installation, the spring piece 21 below the mounting plate 20 is aligned with the conical block 22 and pressed into the mounting hole on the vehicle body. The conical block 22 is pressed, causing the spring piece 21 to elastically deform and retract to pass through the hole. Subsequently, the spring piece 21 rebounds, causing the locking surface 23 to tightly lock onto the back of the mounting hole, achieving lower self-locking. At the same time, the mounting hole 13 of the antenna mounting base 1 is fitted onto the connecting rod 24 of the mounting plate 20 and pressed down. The inclined surface 243 of the slider 242 of the connecting rod 24 is squeezed inward and compresses the return spring 241. When the mounting base 1 is in place, the slider 242 quickly pops out under the action of the spring and locks into the slot in the mounting hole 13, thereby completing the upper locking of the antenna body and the fixed structure. When the antenna is working, the signal captured by the receiver head 12 is transmitted to the signal processor in the mounting base 1 through the extension line 11 for processing, and finally output to the vehicle controller through the connecting line 15 with the protective shell 14.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
