Description

Technical Field

[0001] The utility model relates to the technical field of roof antenna structures, in particular to a roof antenna structure and a vehicle. Background Art

[0002] At present, with the rapid development of the vehicle industry, a large number of electronic devices are installed inside the vehicle, which requires a corresponding number of antennas. The antenna is usually installed on the roof of the vehicle and exposed upward by penetrating the skin of the roof. In the prior art, when waterproofing the antenna, a threading hole is usually directly opened on the skin surface and then sealed with waterproof sealant. The roof will not leak in a short time, but the elastic deformation of the vehicle body caused by the long-term bumpy operation of the vehicle will cause the wiring harness and sealant on the roof skin to become invisible loose, and then the roof will leak, which not only corrodes the vehicle interior, but also because of the roof leakage characteristics: the water at the leaking point will flow along the top cover frame to the far leaking point and leak into the car, so it takes a lot of time to find the invisible leaking point, so it needs to be improved and optimized.

[0030] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0031] like Figures 1 to 4As shown, the present embodiment provides a roof antenna structure, including a vehicle body skin 900, an antenna unit 200 and a protective cover 100; the vehicle body skin 900 is penetrated with a threading hole 901, and the edge of the threading hole 901 is bent to form a first water retaining ring 910; the antenna unit 200 includes an antenna body 210 and a wiring harness 220, the antenna body 210 is fixedly connected to the outer surface of the vehicle body skin 900, one end of the wiring harness 220 is connected to the end of the antenna body 210 close to the vehicle body skin 900, and the wiring harness 220 passes through the threading hole 901; the protective cover 100 is detachably connected to the outer surface of the vehicle body skin 900, and the protective cover 100 is arranged outside the threading hole 901, the vehicle body skin 900 and the protective cover 100 surround a protective cavity, the end of the antenna body 210 away from the vehicle body skin 900 extends out of the protective cavity, and the first water retaining ring 910 is located in the protective cavity.

[0032] The roof antenna structure achieves the purpose of protecting the threading hole 901 by setting a protective cavity, reducing the risk of water entering the threading hole 901. In conjunction with the setting of the first water retaining ring 910, the probability of water in the protective cavity flowing into the threading hole 901 is reduced, reducing the hidden danger of water entering the vehicle. The limitation that the end of the antenna body 210 away from the vehicle body skin 900 extends out of the protective cavity optimizes the positioning method of the antenna body 210, so that the antenna body 210 can be directly set on the vehicle body skin 900, thereby ensuring the positioning effect of the antenna body 210, reducing the hidden danger of the antenna body 210 being separated due to accidents, and ensuring the long-term stable operation of the antenna unit 200; the design of the protective cover 100 detachably connected to the vehicle body skin 900 helps to improve the disassembly and assembly speed of the roof antenna structure, thereby ensuring the convenience of installation and maintenance. The above improvements solve the problem of installing exposed antennas, and achieve the purpose of waterproofing and dustproofing while meeting the use requirements.

[0033] Specifically, the antenna body 210 is bonded to the outer surface of the vehicle body skin 900 by glue.

[0034] In this embodiment, the roof antenna structure further includes a plurality of locking bolts 300, the vehicle body skin 900 is penetrated with mounting holes 902, the mounting holes 902 are the same in number and correspond one to one with the locking bolts 300, the protective cover 100 is fixed with fixing units 110, the fixing units 110 are the same in number and correspond one to one with the locking bolts 300, and each locking bolt 300 passes through a mounting hole 902 and is screwed to a fixing unit 110. Specifically, all fixing units 110 are evenly spaced at the edge of the protective cover 100, and two locking bolts 300 are provided.

[0035] The locking bolt 300 and the fixing unit 110 are screwed together to realize the detachable connection of the protective cover 100 on the vehicle body skin 900. The above structure is simple and reliable, easy to assemble and disassemble, low in production cost, high in connection stability and long in service life.

[0036] Furthermore, the fixing unit 110 includes a bending plate 111 and a locking nut 112. The bending plate 111 is bent at an edge of the protective cover 100 close to one end of the vehicle body skin 900. The locking nut 112 is fixed to the bending plate 111. The locking nut 112 is threadedly matched with the locking bolt 300.

[0037] The structure of the bent plate 111 and the locking nut 112 ensures that the relative position of the locking nut 112 and the protective cover 100 remains unchanged, thereby ensuring that the locking bolt 300 can be stably connected to the fixing unit 110. The above structure is simple and reliable, occupies a small space and has a low production cost. Among them, the design of the bent plate 111 bent at the edge of the protective cover 100 reduces the processing cost and improves the structural strength of the fixing unit 110. Specifically, the locking nut 112 is welded to the bent plate 111.

[0038] Furthermore, the bent plate 111 is placed in the protective cavity. The above design can reduce the space occupied by the roof antenna structure, and also helps to improve the aesthetics of the roof antenna structure.

[0039] In this embodiment, one side of the bent plate 111 is attached to the outer surface of the vehicle body skin 900, and the other side is fixed with a locking nut 112. The above design optimizes the structure of the fixing unit 110, reduces the risk of deformation of the bent plate 111, ensures the connection stability of the locking nut 112 on the bent plate 111, and reduces the space occupied by the fixing unit 110.

[0040] For example, the bent plate 111 is penetrated with an avoidance hole, which is connected to the screw hole of the locking nut 112. With the above arrangement, the screw rod of the locking bolt 300 and the screw hole of the locking nut 112 are smoothly matched, the specific structure of the fixing unit 110 is simplified, the space occupied by the fixing unit 110 is reduced, and the protective cover 100 is smoothly disassembled and assembled on the vehicle body skin 900, thereby improving the convenience of installation and maintenance.

[0041] In this embodiment, the locking nut 112 is an M6 welding nut, and the locking bolt 300 is an M6×16 hexagonal flange bolt. The above definition is simple and effective, and while ensuring the connection stability between the locking nut 112 and the locking bolt 300, it also reduces the production cost and the difficulty of manufacturing.

[0042] In this embodiment, the edge of the mounting hole 902 is bent to form a second water retaining ring, and the second water retaining ring is located in the protective cavity.

[0043] By providing the second water retaining ring, the probability of water in the protective cavity flowing into the mounting hole 902 can be reduced, thereby further reducing the hidden danger of water entering the vehicle.

[0044] Exemplarily, the protective cover 100 is provided with a through hole 101 , the antenna body 210 is passed through the through hole 101 , and the projection of the through hole 101 on the outer surface of the vehicle body skin 900 is spaced apart from the projection of the threading hole 901 on the outer surface of the vehicle body skin 900 .

[0045] The limitation that the antenna body 210 is connected to the penetration hole 101 ensures the working effect of the antenna body 210 while ensuring the sealing effect of the protective cavity; the limitation that the projection interval between the penetration hole 101 and the threading hole 901 on the outer surface of the vehicle body skin 900 is set can prevent water entering from the penetration hole 101 from directly flowing into the threading hole 901, thereby greatly reducing the probability of water entering the threading hole 901.

[0046] Furthermore, the projection of the through hole 101 on the outer surface of the vehicle body skin 900 is spaced apart from the projections of all the mounting holes 902 on the outer surface of the vehicle body skin 900. The spaced apart projections of the through hole 101 and the mounting holes 902 on the outer surface of the vehicle body skin 900 can prevent water entering from the through hole 101 from directly flowing into the mounting holes 902, thereby greatly reducing the probability of water entering the mounting holes 902.

[0047] Exemplarily, the length direction of the antenna body 210 is perpendicular to the outer surface of the vehicle body skin 900. Specifically, the outer surface of the vehicle body skin 900 is horizontal to the ground.

[0048] The above design improves the specific structure of the roof antenna structure, helps to prevent water entering from the connection hole 101 from directly flowing into the threading hole 901 and the installation hole 902, and further reduces the probability of water entering the threading hole 901 and the installation hole 902. At the same time, the above improvement also simplifies the specific structure of the roof antenna structure, reduces the space occupied, and helps to improve the overall aesthetics.

[0049] This embodiment also provides a vehicle, including a communication module and the above-mentioned roof antenna structure, and the other end of the wiring harness 220 is connected to the communication module.

[0050] The vehicle uses a wiring harness 220 to connect the communication module and the antenna body 210, thereby ensuring the smooth transmission and reception of information by the vehicle. While reducing the risk of water entering the vehicle, it ensures the stable operation of the roof antenna structure, thereby improving the user experience of the vehicle.

[0051] This embodiment also provides a method for installing a roof antenna structure, which is applied to the above-mentioned roof antenna structure and includes the following steps:

[0052] Step 1: Install the antenna body 210 on the outer surface of the vehicle body skin 900 and pass the wire harness 220 through the threading hole 901 .

[0053] Step 2: Cover the protective cover 100 outside the threading hole 901 , and connect the antenna body 210 to the threading hole 101 .

[0054] Step 3: Make all the locking bolts 300 pass through the vehicle body skin 900 and threadably connect with the locking nuts 112 .

[0055] When disassembling the roof antenna structure, the antenna unit 200 and the protective cover 100 can be removed from the vehicle body skin 900 by performing the above steps in reverse. The specific operation steps are conventional technical means in this field and will not be described in detail here.

[0056] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here.
