Description

Technical Field

[0001] This utility model relates to the field of vehicle antenna technology, and in particular to a vehicle antenna suitable for panoramic sunroofs. Background Technology

[0002] Common panoramic sunroofs typically consist of almost the entire roof made of glass and can be opened for ventilation. Some panoramic sunroofs, while not opening, are large enough to enhance the car's sense of openness. Because of the presence of a panoramic sunroof, traditional methods of installing a vehicle antenna in the sunroof area are not feasible. Poor placement can easily lead to poor antenna signal reception or interference from other devices.

[0003] Therefore, it is necessary to develop a vehicle-mounted antenna for panoramic sunroofs. On the one hand, the installation position of the antenna chassis should avoid the sunroof opening or glass area to avoid affecting the normal use of the sunroof, while ensuring that the antenna has a good signal reception environment. On the other hand, since panoramic sunroofs have high aesthetic requirements for some vehicles, the design of the antenna chassis should be integrated with the overall appearance of the vehicle as much as possible and should not be too abrupt.

For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. Additionally, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0019] Example 1, as Figures 1-11 As shown, a vehicle-mounted antenna suitable for panoramic sunroofs includes: a chassis body 1, with an outwardly extending fixing post 21 and a cable guide tube 22 on one side of the chassis body 1, and an outwardly protruding isolation platform 11 on the surface of the chassis body 1. The isolation platform 11 forms a waterproof protrusion around the fixing post 21 and the cable guide tube 22 on the chassis body 1. The fixing post 21 has a cable through hole 211, and the cable guide tube 22 has a cable through hole. Specifically, opposing clearance platforms 212 are provided on the mating protrusion, and the fixing post 21 spans the spaced clearance platforms 212, with a gap reserved between the spaced clearance platforms 212 that is longitudinally connected to the fixing post 21; the fixing post 21 has a thread 213.

[0020] Specifically, on the other side of the chassis body 1, a mating boss is provided to mate with the cover 5. A second isolation platform 12, embedded within the cover 5, is provided on the mating boss, forming a mounting cavity around the mating boss. The mounting cavity has through holes communicating with the wire hole 211 and the wire passage hole, respectively. A ring of outwardly extending peripheral protrusions 15 is formed on the outer edge of the mating boss of the chassis body 1. More specifically, the chassis body 1 has several cover assembly holes 31 arranged around the second isolation platform 12. The mating boss fits into the mounting ring platform 51 of the cover 5, and is assembled and connected to the mounting holes 52 on the mounting ring platform 51 via connectors through the cover assembly holes 31. On the side of the chassis body 1 where the fixing post 21 is located, several rings of peripheral protrusions 32 are also provided at intervals around the outer periphery of the first isolation platform 11.

[0021] Furthermore, an elastic coating layer 4 is provided on the side of the chassis body 1 where the mating boss is located. The elastic coating layer 4 has clearance grooves 41 corresponding to the wire passage holes and wire threading holes 211. The elastic coating layer 4 is made of TPV material, which is a material used in the prior art, and the shape of the elastic coating matches the shape of the side of the chassis body 1 where the mating boss is located.

[0022] In Example 2, based on Example 1, an elastic overlay layer 4 is injection molded onto the chassis body 1. The elastic overlay layer 4 is made of TPV material, a material used in the prior art, and its shape matches the shape of the side of the chassis body 1 where the mating boss is located.

[0023] In embodiment three, based on embodiment one or two, the isolation platform 2 12 is provided with several protruding positioning posts 13 and / or positioning holes 14, which are used to position and assemble the circuit board onto the chassis body 1. In this embodiment, both positioning posts 13 and positioning holes 14 are provided. The chassis body 1 has a boat-shaped structure that is narrow at both ends and wide in the middle.

[0024] Furthermore, in this embodiment, the adhesive of the elastic coating layer 4 is directly applied to the chassis body 1 using an existing injection molding process. The circuit board is assembled on the chassis body 1, which is covered with the elastic coating layer 4, and has mating bosses. Positioning is achieved by interlocking the positioning pins 13 with the positioning mounting holes of the circuit board, and the circuit board is screwed onto the positioning holes 14 using screws. The elastic coating layer 4 is made of SANTOPRENE 121-50M100TPV material for waterproof protection. This material is UV-resistant, a thermoplastic vulcanized elastomer, and has good physical properties and chemical resistance, resulting in a longer service life. The chassis body 1 of the vehicle antenna adopts an integrated die-casting process, and the flatness can reach less than 0.3mm. The chassis has a fixing post 21 with thread 213, which is convenient and stable for installation. The antenna through hole 211 and the ground wire through hole are designed separately, which reduces interference and increases safety. The waterproof material is UV resistant and soft TPV, which has a longer service life. This material is also easy to recycle and has little impact on the environment.

[0025] Working principle: This utility model discloses a vehicle-mounted antenna suitable for panoramic sunroofs, designed to work seamlessly with the sunroof without interfering with its opening and closing. The antenna chassis operates smoothly alongside the sunroof, and the side of the chassis body that connects to the cover is covered with an elastic rubber layer, improving waterproofing and extending service life. A threaded fixing post extends from the bottom of the antenna chassis, enhancing installation stability. The fixing post has a recessed cable routing hole in the middle for easy antenna wiring. A cable guide for the ground wire is also located next to the fixing post, allowing for separate routing of the antenna and ground wires to prevent static electricity generated during vehicle operation from affecting safety.
