Description

Technical Field

[0001] The present disclosure relates to the technical field of vehicle-mounted antennas, and in particular to a vehicle antenna with an anti-friction structure and a new energy vehicle. Background Art

[0002] Shark fin antennas have good comprehensive performance in appearance, wind resistance and safety, and more and more cars are using shark fin antennas as car antenna structures. Generally, when installing a shark fin antenna, the antenna is set in the space formed by the connection between the shell and the base. However, since the shark fin antenna needs to be installed through structures such as nuts, the antenna structure is unstable during the installation process, resulting in inconvenience in antenna installation.

[0003] In order to solve the above problems, a Chinese patent with publication number CN 112151942 A discloses a shark fin antenna with a pre-installation structure, including a shell, a pre-installation mechanism and a fixing mechanism, the shell includes an upper shell and a lower shell, the pre-installation mechanism and the fixing mechanism are both fixed to the outside of the lower shell; the pre-installation mechanism includes two groups of plug rods, the two groups of plug rods are arranged in parallel on the outside of the lower shell, the ends of the two groups of plug rods are provided with first clamping blocks, and the two groups of the first clamping blocks are both arranged on the outside of the plug rods. The shark fin antenna of the present invention is provided with a pre-installation mechanism and a fixing mechanism. When the shark fin antenna is installed on the roof, the shark fin antenna can be pre-installed on the roof through the pre-installation structure, and then the shark fin antenna can be completely fixed to the roof through the fixing mechanism, so that the shark fin antenna is more convenient to install and the installation position is more accurate.

[0004] The shark fin antenna is provided with a pre-installation mechanism and a fixing mechanism, so that the shark fin antenna is more convenient to install and the installation position is more accurate. The bottom of the antenna is electrically connected to the circuit board, and the top of the antenna is generally in contact with the shell to achieve a better fixing effect on the antenna. However, since the car vibrates during driving, especially when encountering a road with poor road conditions, the vibration amplitude is greater. In this way, the friction between the antenna and the shell is more intense during the vibration process, and the long-term friction between the antenna and the shell can easily cause damage to the antenna.

[0005] Therefore, there is a need for a car antenna that can prevent the antenna from being damaged due to friction between the antenna and the housing. Utility Model Content

Even if the antenna structure vibrates greatly, the antenna assembly will not directly rub against the outer shell, and the friction between the wear-resistant protective part and the antenna assembly is small, thereby avoiding damage to the antenna assembly due to friction.

[0029] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0030] like Figure 1 and Figure 2 As shown, an automobile antenna 10 with an anti-friction structure in one embodiment includes a housing 100, a base 200 and an antenna mechanism 300, wherein the housing 100 and the base 200 are detachably connected; the antenna mechanism 300 includes a circuit board 310, an antenna assembly 320 and a wear-resistant protective member 330, wherein the circuit board 310 is connected to the base 200, the antenna board is electrically connected to the circuit board 310, one side of the wear-resistant protective member 330 is connected to one end of the antenna assembly 320 adjacent to the housing 100, and the other side of the wear-resistant protective member 330 is in contact with the housing 100.

[0031] In this embodiment, the housing 100 is provided with a housing cavity 101, and the space of the housing cavity 101 is large enough so that the antenna mechanism 300 and the base 200 are both located in the housing cavity 101 and protected by the housing 100; the base 200 is provided with a through hole 201 so that the external wire can pass through the base 200 and be electrically connected to the circuit board 310. One side of the wear-resistant protective member 330 is connected to one end of the antenna assembly 320 adjacent to the outer shell 100. Specifically, the wear-resistant protective member 330 covers and is bonded to one end of the antenna assembly 320 adjacent to the outer shell 100, so that the antenna assembly 320 is completely isolated from the outer shell 100. The other side of the wear-resistant protective member 330 abuts against the outer shell 100. Specifically, the shape of the wear-resistant protective member 330 is adapted to the shape of the outer shell 100, so that the other side of the wear-resistant protective member 330 completely abuts against the outer shell 100, that is, the wear-resistant protective member 330 is clamped between the antenna assembly 320 and the outer shell 100, so that there is no direct contact between the antenna assembly 320 and the outer shell 100.

[0032] The above-mentioned automobile antenna 10 with an anti-friction structure is connected to one end of the antenna component 320 adjacent to the shell 100 through one side of the wear-resistant protective part 330, and the other side of the wear-resistant protective part 330 abuts against the shell 100, that is, the wear-resistant protective part 330 is clamped between the antenna component 320 and the shell 100, so that the antenna component 320 and the shell 100 cannot be in direct contact with each other. Even if the antenna structure vibrates greatly, the antenna component 320 will not directly rub against the shell 100, and the friction between the wear-resistant protective part 330 and the antenna component 320 is small, thereby avoiding damage to the antenna component 320 due to friction.

[0033] like Figure 1 and Figure 2 As shown, in one embodiment, the wear-resistant protective member 330 includes a fixing portion 331 and a wear-resistant portion 332, one end of the fixing portion 331 is connected to the circuit board 310, and the other end of the fixing portion 331 is connected to the wear-resistant portion 332, and the wear-resistant portion 332 covers the top of the antenna assembly 320.

In this embodiment, the wear-resistant portion 332 is in a strip shape and covers the top of the antenna assembly 320, so that the wear-resistant portion 332 completely covers the top of the antenna assembly 320, so that the protection effect of the wear-resistant portion 332 is better.

[0035] like Figure 2 As shown, in one embodiment, the wear-resistant portion 332 is an insulating protective rubber. In this embodiment, the wear-resistant portion 332 is made of rubber, which has good insulation and deformability. The insulation property makes the wear-resistant portion 332 not interfere with the normal operation of the antenna assembly 320, and the deformability makes the friction between the wear-resistant portion 332 and the antenna assembly 320 negligible, effectively preventing the antenna assembly 320 from being damaged due to friction.

[0036] like Figure 2 As shown, in one embodiment, the thickness of the wear-resistant portion 332 is 1 cm-2 cm. In this embodiment, the thickness of the wear-resistant portion 332 is 1.5 cm, so that the wear-resistant portion 332 is just clamped between the housing 100 and the antenna assembly 320. The thickness of the wear-resistant portion 332 can also be designed to other sizes according to the requirements of different products.

[0037] like Figure 2 As shown, in one embodiment, the width of the wear-resistant portion 332 is 3 cm-4 cm. In this embodiment, the width of the wear-resistant portion 332 is 3.5 cm, so that the wear-resistant portion 332 can completely cover the top of the antenna assembly 320, so that the protection effect of the wear-resistant portion 332 is better.

In this embodiment, the mounting post 400 is fixedly connected to the base 200, which facilitates the installation of the antenna, and the mounting post 400 also plays a role in fixing the base 200.

[0040] like Figure 2 As shown, in one embodiment, the car antenna 10 with an anti-friction structure further includes a first fastener 500, the circuit board 310 is provided with a first connection hole 310a, the base 200 is provided with a second connection hole (not shown), and the first fastener 500 passes through the first connection hole 310a and the second connection hole in sequence, so that the circuit board 310 is fixedly connected to the base 200. In this embodiment, the first fastener 500 is a screw, and the screw passes through the first connection hole 310a and the second connection hole, so that the circuit board 310 is installed on the base 200, thereby improving the connection strength between the circuit board 310 and the base 200.

[0041] The present application also provides a new energy vehicle, comprising a vehicle body and the vehicle antenna 10 with an anti-friction structure as described in any of the above embodiments, wherein the vehicle antenna 10 with an anti-friction structure is installed on the top of the vehicle body.

[0042] Compared with the prior art, the present invention has at least the following advantages:

[0043] The above-mentioned automobile antenna 10 with an anti-friction structure is connected to one end of the antenna component 320 adjacent to the shell 100 through one side of the wear-resistant protective part 330, and the other side of the wear-resistant protective part 330 abuts against the shell 100, that is, the wear-resistant protective part 330 is clamped between the antenna component 320 and the shell 100, so that the antenna component 320 and the shell 100 cannot be in direct contact with each other. Even if the antenna structure vibrates greatly, the antenna component 320 will not directly rub against the shell 100, and the friction between the wear-resistant protective part 330 and the antenna component 320 is small, thereby avoiding damage to the antenna component 320 due to friction.
