Description

Technical Field

[0001] This utility model relates to the field of vehicle-mounted communication equipment technology, and in particular to a vehicle-mounted antenna that facilitates fixing a substrate. Background Technology

[0002] With the rapid development of intelligent connected vehicles and vehicle communication technology, vehicle antennas, as key components for realizing functions such as GPS positioning, 4G, 5G communication, vehicle networking, Bluetooth and Wi-Fi, are receiving increasing attention for their performance stability and installation reliability. Antennas are usually composed of antenna substrate, radiating element, feeding structure and external protective shell. Among them, the stable installation of antenna substrate directly affects the stability of signal transmission and the overall shock resistance of the product.

[0003] Currently, most vehicle antennas use screws or adhesive to fix the antenna substrate inside the mounting housing. While screw fixing provides a secure connection, it has the following drawbacks: First, the assembly process is complex, requiring tools for tightening, which increases production time, labor costs, and material costs. Second, it is not conducive to later maintenance and replacement, as disassembly is difficult and the substrate is easily damaged. While adhesive fixing can achieve screwless assembly, it has problems such as long curing time, adhesion strength being greatly affected by temperature and humidity, difficulty in disassembly and recycling, and difficulty in repairing once the adhesion fails.

[0004] Therefore, there is an urgent need to provide a vehicle-mounted antenna that is easy to fix the substrate, so as to achieve screwless installation, quick assembly and disassembly, and improve product production efficiency and service life. Utility Model Content

[0005] To overcome the drawbacks of traditional vehicle antennas that typically use screws or adhesives to fix the antenna substrate inside the housing, which involves complex assembly processes and requires additional tools, increasing production time, labor costs, and material costs, this invention provides a vehicle antenna that facilitates substrate fixing.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a vehicle-mounted antenna for easy fixing of a substrate, comprising a mounting housing, an antenna substrate mounted inside the mounting housing, a plurality of slots formed on the upper surface of the antenna substrate, a plurality of elastic U-shaped buckles matching the slots fixedly connected to the corresponding positions on the inner wall of the mounting housing, a plurality of limiting grooves formed on the middle surface of the antenna substrate, and a plurality of elastic inclined buckles matching the limiting grooves fixedly connected to the inner bottom of the mounting housing.

[0007] As an improvement to the above solution, the elastic U-shaped buckle and the elastic inclined buckle are made of elastic materials and designed as resettable buckle structures based on the principle of elastic deformation.

[0008] As an improvement to the above solution, the side of the elastic inclined buckle closest to the installation space is configured as a guide inclined surface.

[0009] As an improvement to the above solution, the inner wall of the mounting shell is fixedly provided with symmetrically distributed fixing seats, and the fixing seats are provided with arc-shaped buckles.

[0010] As an improvement to the above solution, a mounting hole is provided at one end of the mounting housing.

[0011] As an improvement to the above solution, a cross-shaped grid frame is provided at the bottom of the mounting housing. Multiple front limiting protrusions and multiple rear limiting protrusions are fixed to one end of the cross-shaped grid frame near the mounting space. The front limiting protrusions and the rear limiting protrusions are arranged opposite to each other to form a front and rear limiting and clamping design.

[0012] As an improvement to the above solution, both sides of the elastic U-shaped buckle are provided with chamfers.

[0013] As an improvement to the above solution, the arc-shaped buckle has an eight-shaped opening on the side near the center of the outer shell.

[0014] Compared with the prior art, the present invention has the following technical effects: 1. By setting elastic U-shaped buckles and elastic inclined buckles in the mounting housing, and cooperating with the slots and limiting slots on the antenna substrate, screwless installation of the substrate is realized. During assembly, the substrate only needs to be pushed into the housing along the guide direction, and the buckles will automatically engage and position. No tools are required, which simplifies the assembly process, reduces the difficulty of manual operation and production pace, and significantly improves the efficiency of automated assembly.

[0015] 2. By installing the cross-shaped grid frame, front limiting protrusion and rear limiting protrusion set at the bottom of the housing, a front and rear clamping structure is formed, which effectively restricts the movement of the substrate in the lateral and longitudinal directions. Combined with the continuous pressing action of the elastic buckle, the overall structure has excellent vibration and impact resistance, which can effectively avoid problems such as substrate loosening and friction noise caused by bumps or resonance during vehicle operation.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0024] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6A vehicle-mounted antenna for easy fixing of a substrate includes a mounting housing 1. One end of the mounting housing 1 has a mounting hole 3 for use with screws, rivets, or bolts to securely fix the entire vehicle-mounted antenna device to a vehicle bracket, metal base plate, or vehicle body structure, ensuring the structural stability and impact resistance of the antenna under complex driving conditions. The inner wall of the mounting housing 1 is fixedly provided with symmetrically distributed fixing seats 2. Each fixing seat 2 has an arc-shaped buckle 201 for clamping and fixing connecting wires extending from the antenna substrate 7. The arc-shaped buckle 201 has a figure-eight opening on its side near the center of the housing 1, facilitating the insertion of the connecting wires into the arc-shaped buckle 201. The antenna substrate 7 is installed inside the mounting housing 1, and the upper surface of the antenna substrate 7 has three... Each mounting housing 1 has a slot 8, and three elastic U-shaped buckles 9 are fixedly connected to the inner wall of the mounting housing 1 at the corresponding position. The elastic U-shaped buckles (9) have chamfers on both sides to facilitate the insertion of the antenna substrate 7 into the elastic U-shaped buckles 9. The middle surface of the antenna substrate 7 has two limiting grooves 10. The bottom of the mounting housing 1 has two elastic inclined buckles 11 that match the limiting grooves 10. The side of the elastic inclined buckle 11 closest to the installation space is set as a guide inclined surface to guide and position the antenna substrate 7 during installation. In addition, the elastic U-shaped buckles 9 and the elastic inclined buckles 11 are made of elastic material and are designed as resettable buckle structures based on the principle of elastic deformation, ensuring smooth insertion and reliable locking during assembly.

[0025] When the antenna substrate 7 is inserted vertically into the mounting housing 1, its bottom first contacts the inclined surface of the elastic inclined clip 11. Under the action of external force, the elastic inclined clip 11 is forced to undergo elastic deformation, allowing the antenna substrate 7 to slide smoothly. When the substrate reaches the predetermined position, the elastic inclined clip 11 is embedded in the limiting groove 10 on the substrate under the action of elastic restoring force, forming an axial limit, thereby preventing the substrate from falling off. This elastic structure can continuously apply a certain pre-tightening pressure to the substrate under different temperature environments, effectively compensating for dimensional changes caused by thermal expansion and contraction of materials, ensuring the stability of the connection. As the substrate is pressed down into place, the upper slot 8 gradually aligns and engages with the elastic U-shaped buckle 9 on the inner wall of the mounting housing 1. After the U-shaped buckle undergoes elastic deformation, it springs back, clamping the two sides of the slot 8 to achieve lateral positioning and prevent loosening. Through the above structural cooperation, the antenna substrate 7 can be quickly installed and firmly fixed without the use of screws, realizing tool-free assembly, simplifying the production process, and reducing material and labor costs. At the same time, during disassembly, only force needs to be applied to remove the substrate in the opposite direction to achieve quick maintenance and replacement, improving product maintainability and extending service life.

[0026] Example 2: Based on Example 1, please refer to... Figure 3 and Figure 4 The bottom of the mounting housing 1 is provided with a cross-shaped grid frame 4. Six front limiting protrusions 5 and six rear limiting protrusions 6 are fixed to one end of the cross-shaped grid frame 4 near the mounting space. The front limiting protrusions 5 and the rear limiting protrusions 6 are arranged opposite to each other to form a front and rear limiting and clamping design.

[0027] When the antenna substrate 7 is installed, it is first placed accurately in the predetermined position along the guide of the elastic inclined buckle 11 on the inner wall of the mounting housing 1 and the bottom cross grid frame 4. At this time, the front limiting protrusion 5 and the rear limiting protrusion 6 work together to limit the antenna substrate 7 from the front and rear directions, effectively preventing any movement of the substrate in the lateral and longitudinal directions. This ensures that even under complex working conditions, the antenna substrate 7 can remain stable and will not produce abnormal noise or displacement, thereby improving the vibration resistance and reliability of the entire device.
