Description

Technical Field

[0001] This utility model relates to the field of automotive antenna technology, and in particular to a spoiler-integrated combined antenna. Background Technology

[0002] Currently, automotive antenna technology, including AM / FM+DAB radio antennas, GNSS navigation antennas, and 4G & 5G communication antennas, primarily utilizes shark fin antenna integration, separate glass antenna modules, or built-in integrated separate module antennas. However, the widespread use of window tinting in modern cars, employing metal films and coating technologies, can shield these antennas from signals, increasing the demand for external antennas. Therefore, integrated antenna designs reduce the number of antennas and installation positions, lowering automotive wiring costs and signal loss. For example, patent CN217507638U discloses a multi-functional integrated spoiler automotive antenna, which further integrates the antenna design into the car spoiler, conformally designing it to the spoiler structure. However, this patent uses ordinary plug-in connectors, resulting in poor overall waterproofing and insufficient environmental adaptability. Utility Model Content

[0003] To address the problem of poor waterproofing performance of existing integrated spoiler vehicle antennas, this invention provides a spoiler-integrated combined antenna that improves waterproofing performance.

[0004] The technical solution adopted by this utility model to solve its technical problem is: A spoiler-integrated combined antenna includes a housing, a base, a waterproof gasket, a PCB circuit board, a GNSS dielectric antenna, an AM / FM antenna, a DAB antenna, a 4G & 5G communication antenna, an output line, and a connector. The GNSS dielectric antenna, AM / FM antenna, DAB antenna, and 4G & 5G communication antenna are all integrated and mounted on the PCB circuit board, and the PCB circuit board is fixedly mounted on the base. The PCB circuit board has a power feeding hole for each antenna, and each antenna is electrically connected to the PCB circuit board. The PCB circuit board is connected to an output line, which extends to the outside and is fitted with the connector. The outer shell and the base are fixed together to form an integral encapsulation structure, and the waterproof gasket is assembled between the outer shell and the base to achieve a seal and waterproofing.

[0005] Furthermore, the base is provided with several limiting grooves for limiting the waterproof rubber pad. The edge of the waterproof rubber pad is integrally provided with a limiting piece that matches the shape of the limiting groove for being inserted into the limiting groove. The limiting groove is open on the outside, and the width of the limiting groove is greater than the width of the opening, thereby locking the waterproof rubber pad to prevent it from deforming and shifting. A limiting groove is provided on the base, and a limiting piece matching the shape of the limiting groove is integrally set on the edge of the waterproof gasket. The waterproof gasket is fixed to the base by the limiting piece snapping into the limiting groove, which can effectively prevent the waterproof gasket from deforming and shifting during assembly and use, keeping the waterproof gasket in the set position, which helps maintain the stability of the seal and ensures reliable waterproof effect. The outer opening of the limiting groove is wider than the inner width of the opening, forming a snap-fit ​​structure that is wider inside and narrower outside. After the limiting piece is snapped into the limiting groove from the outside, it is limited by the groove wall and is not easy to fall out. This not only ensures the firmness of the snap-fit, but also facilitates the assembly operation without the need for additional fixing parts. The limiting piece and the waterproof gasket are set as one piece, eliminating the process of separately processing and assembling fixing parts, which helps to simplify the structure, facilitate manufacturing and assembly, and reduce production costs. The base has several limiting grooves. Through the multi-point cooperation of multiple limiting pieces and limiting grooves, multiple parts of the waterproof gasket can be simultaneously limited, further preventing local deformation and shifting and improving the reliability of the limiting.

[0006] Furthermore, the limiting groove is a T-shaped groove. After the limiting piece is inserted, it is not only restricted along the opening direction, but also limited by the groove wall in the width direction of the groove. This provides multi-directional limiting for the waterproof gasket, further preventing deformation and displacement of the waterproof gasket and ensuring a stable sealing position. The T-shaped groove structure is simple; the limiting piece can be inserted from the opening side of the T-shaped groove to complete the assembly without the need for additional fasteners. This simplifies the assembly process, facilitates installation, and reduces manufacturing and assembly costs.

[0007] Furthermore, the base is equipped with shielding cavity mounting wall columns to form a partitioned shielding structure. These wall columns are primarily positioned below the GNSS dielectric antenna to protect the receiving front-end from interference from other signals.

[0008] Furthermore, the base is equipped with PCB support bosses and screw mounting posts. The screw mounting posts are used to engage screws to secure the PCB circuit board.

[0009] Furthermore, the 4G & 5G communication antenna is mounted on the PCB circuit board in a T-shape. The T-shape consists of a horizontal extension and a vertical extension, which allows the antenna radiator to be effectively deployed within the plane of the circuit board. The overall height is low, which is beneficial for hiding the antenna in the narrow space inside the vehicle, adapting to hidden installation inside the vehicle, and meeting the requirements for roof-mounted antennas.

[0010] Furthermore, the 4G & 5G communication antenna adopts a metal vibrator antenna or a PCB vibrator antenna.

[0011] Furthermore, the PCB circuit board is provided with two 4G & 5G communication antennas and antenna mounting matching slots corresponding to each antenna. Each antenna is fixed to the PCB circuit board and connected by soldering.

[0012] Furthermore, the outer shell is a cuboid structure made of plastic, and the outer shell is provided with mounting studs. The outer shell and the base are locked and fixed together by self-tapping screws.

[0013] Furthermore, the output line is a coaxial line, which is led out from the outlet on the base, and the connector is crimped to the end of the coaxial line.

[0014] Beneficial effects: This structure integrates multiple functional units, combining antennas and other components into a single integrated design. It meets customers' needs for roof-mounted antennas without external placement, simplifies the roof's appearance, avoids issues such as wind noise, appearance interference, and installation damage associated with external antennas, optimizes the roof structure layout, and uses waterproof gaskets between the outer shell and the base to form a seal at the joint, preventing external moisture and dust from seeping into the interior through the shell seams. This ensures the internal circuitry and antenna operate normally in humid and water-related environments, improving the product's environmental adaptability. The product adopts a modular design architecture, with each functional unit operating independently. Functions can be flexibly added, removed, or combined according to different vehicle models and customer configuration requirements, allowing for multiple functional options and strong versatility, facilitating derivative development. The overall assembly shape and installation interface have been optimized to fit multiple installation points within the vehicle, compatible with various vehicle models and interior space layouts, and not limited by a single installation location, resulting in wider adaptability.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0019] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0020] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0021] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0022] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0023] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0024] like Figure 1-6 The present invention relates to a spoiler-integrated combined antenna, comprising a housing 1, a base 2, a waterproof pad 3, a PCB circuit board 4, a GNSS dielectric antenna 5, an AM / FM antenna 6, a DAB antenna 7, a 4G & 5G communication antenna 8, an output line 9, and a connector 10.

[0025] The GNSS dielectric antenna 5, AM / FM antenna 6, DAB antenna 7, and 4G & 5G communication antenna 8 are all integrated and mounted on the PCB circuit board 4, which is fixedly mounted on the base 2.

[0026] Each antenna has a feed hole on the PCB circuit board 4, and each antenna is electrically connected to the PCB circuit board 4.

[0027] The PCB circuit board 4 is connected to an output line 9, which extends outward and is fitted with a connector 10. Specifically, the output line 9 is a coaxial cable, which is led out from the cable outlet 25 provided on the base 2. The end of the coaxial cable is crimped with a connector 10, preferably a FAKRA connector.

[0028] The outer shell 1 and the base 2 cooperate and fix each other to form an integral encapsulation structure, such as Figure 4 The waterproof gasket 3 is assembled between the outer shell 1 and the base 2 to achieve a seal and waterproofing. Preferably, the base 2 is provided with a plurality of limiting grooves 21 for limiting the waterproof gasket 3. The edge of the waterproof gasket 3 is integrally provided with a limiting piece 31 that matches the shape of the limiting groove 21 for engaging with the limiting groove 21. The limiting groove 21 has an opening on the outside, and the width of the inner side of the limiting groove 21 is greater than the width of the opening, thereby securing the waterproof gasket 3 and preventing its deformation and displacement. As a preferred embodiment, the limiting groove 21 is a T-shaped groove. The waterproof gasket 3 and the base 2 are secured by the locking piece 31 engaging with the locking groove 21. This effectively prevents the waterproof gasket 3 from deforming or shifting during assembly and use, ensuring that the waterproof gasket 3 remains in the set position. This helps maintain a stable seal and ensures reliable waterproofing. The locking groove 21 has an outer opening and an inner width greater than the opening width, forming a locking structure that is wider inside and narrower outside. Once the locking piece 31 is engaged with the locking groove 21 from the outside, it is restrained by the groove wall and is not easily dislodged. This ensures a strong connection and facilitates assembly without the need for additional fixing parts. The locking piece 31 and the waterproof gasket 3 are integrated, eliminating the need for separate processing and assembly of fixing parts. This simplifies the structure, facilitates manufacturing and assembly, and reduces production costs. The base 2 has several locking grooves 21. Through the multi-point engagement of multiple locking pieces 31 with the locking grooves 21, multiple points of the waterproof gasket 3 can be simultaneously locked, further preventing local deformation and shifting and improving the reliability of the locking mechanism.

[0029] like Figure 3 The base 2 is equipped with shielding cavity mounting wall columns 22 to form a partitioned shielding structure. The shielding cavity mounting wall columns 22 are mainly located below the GNSS dielectric antenna 5 to protect the receiving front end from interference from other signals, but they can also be located in other positions.

[0030] The base 2 is provided with a PCB support boss 23 and a screw mounting post 24. The screw mounting post 24 is used to fix the PCB circuit board 4 with screws.

[0031] The 4G & 5G communication antenna 8 is mounted on the PCB circuit board 4 in a T-shape. The 4G & 5G communication antenna 8 adopts a metal vibrator antenna or a PCB vibrator antenna.

[0032] The PCB circuit board 4 is equipped with two 4G & 5G communication antennas 8 and antenna mounting matching slots corresponding to each antenna. Each antenna is fixed and connected to the PCB circuit board 4 by soldering.

[0033] The outer shell 1 is a rectangular structure made of plastic. The outer shell 1 is equipped with mounting studs, and the outer shell 1 and the base 2 are locked together by self-tapping screws.

[0034] Installation Requirements: The antenna should be installed in the metal bracket 11 inside the spoiler or in another location inside the vehicle. The antenna must be installed and fixed horizontally, with an installation angle error of within 5 degrees relative to the horizontal plane. There should be no metal obstructions directly blocking the angle of installation above 120 degrees. All metal parts must be kept away from the antenna body, and there should be no metal within 50mm of the antenna body, or at low elevation angles. The antenna should be kept away from radiating interference components, such as transmitters and EMC interference sources. The antenna output line 9 should be secured with clips according to the pre-defined route and wrapped with foam to prevent abnormal noise. The antenna grounding must be adequate; poor grounding will affect the antenna performance and may even cause the antenna to malfunction.

[0035] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
